Dendritic cells (DC) used in therapeutic cancer immunotherapy have to be able to stimulate T cells resulting in an immune response that can efficiently target the cancer cells. One of the critical hurdles has been the lack of IL-12p70 production when maturating the DC, which is rectified by using the bacterial preparation OK432 (trade name Picibanil) to mature the cells. In order to identify the mechanism behind OK432 stimulation of DC, we investigated the contribution of different TLR to examine their involvement in IL-12p70 production. By combining different inhibitors of TLR signaling, we demonstrate here that TLR3 is responsible for the IL-12p70 production of DC induced by OK432. Moreover, our data suggest that the ligand triggering IL-12p70 secretion upon TLR3 stimulation is sensitive to proteinase and partly also RNAse treatment. The fact that a bacterial compound like OK432 can activate the TLR3 pathway in human DC is a novel finding. OK432 demonstrates a critical ability to induce IL-12p70 production, which is of great relevance in DC based cancer immunotherapy. PMID:22363584

To determine the efficacy of OK-432 sclerotherapy in the treatment of lymphangiomas. The treatment was begun for 14 patients with lymphangioma. The age range of the patients at the time of the first injection was from 10 months to 42 years. Eleven of the lesions involved the head and neck region, two the thorax and one was localized in the extremity. Prior to treatment all patients were investigated with either magnetic resonance imaging, computed tomography, ultrasound or a combination of these modalities. The injections were performed with ultrasound and/or fluoroscopic guidance. Eight patients received OK-432 as first-line treatment; five were treated after surgery and one after medical therapy. On average, 2.2 intracystic injections were performed per patient. Nine of the lesions were macrocystic and five were mixed lesions. Eleven patients showed complete or marked response to the OK-432 sclerotherapy, two patients had moderate shrinkage of their lesions and only one patient showed no response to therapy. Macrocystic lesions showed the best response to therapy. Those patients who received OK-432 as first-line treatment showed complete or marked response. It was found that treatment of lymphangiomas with OK-432 was safe and effective.

Although surgery is the first choice of therapy for plunging ranula, it is associated with technical difficulties, morbidity and recurrence. Plunging ranula may be also primarily treated with nonsurgical sclerotherapy, but there is little experience in pediatric patients. We, therefore, assessed the efficacy of OK-432 sclerotherapy for pediatric plunging ranula. Nine children with plunging ranula were prospectively treated with intracystic injections of OK-432. At the outpatient clinic, the ranula was punctured in the neck and aspirated mucus was replaced with 0.1-0.2mg OK-432 solution. The size of the ranula was compared before and after sclerotherapy. Total or nearly total shrinkage was observed in 6 of 9 patients; marked reduction (>50% of original size) in 2; and partial reduction (<50% of original size) in 1. At a mean follow-up of 26 months after last sclerotherapy, recurrence was observed in only 1 patient; this patient showed complete response after reinjection of OK-432 solution. No significant complications were observed, with only fever and mild local pain observed in 4 patients for 2-4 days after treatment. OK-432 sclerotherapy is safe and effective in the treatment of pediatric plunging ranula. Sclerotherapy may become a primary treatment modality prior to surgery.

Nonsurgical treatments, such as sclerotherapy have been attempted for head and neck lymphagiomas. Of the available sclerosing agents, picibanil has shown satisfactory short-term treatment results in many studies, but no study has presented long-term treatment results. Accordingly, in the present study, the authors retrospectively reviewed the long-term treatment results of picibanil sclerotherapy. Fifty-five lymphangioma patients who underwent picibanil sclerotherapy were enrolled. Data about initial and long-term response, recurrence, and excision rate were collected. Initial response rates were 83.5 percent and long-term response rates were 76.3 percent. Initial and the long-term response rate were equally good for lymphangioma.

Lymphatic malformations (LM) are benign structural defects that can cause serious complications because of their size and location. Traditionally, surgical removal was the first treatment modality, but this could be associated with many complications and risks. Since Ogita introduced OK-432 (picibanil) in 1987 as a treatment method, this sclerosant has become popular. This paper is a review of the trials published so far on this topic. A literature search of English trials with 5 or more patients in it with LM who had never been treated before was done. The paper had to use the microcystic-macrocystic classification and have a mean follow-up of more than a year to be included in this review. Results were classified as "excellent" when the lesions show a regression of more than 90%, "good" when regression is more than 50%, and "poor" when shrinkage is less than 50% (this also includes no response at all). Twenty-seven percent of microcystic LMs show an excellent result; 33%, a good result; and 40%, a poor result. Of the macrocystic LMs, 88% have excellent results. Recurrence rates vary from 5% to 8%. The adverse effects are mostly mild. Most trials have a short follow-up; therefore, there are uncertainties when it comes to cure and regression. Mostly, the adverse effects of OK-432 are trivial and disappear after a week, but the need for a temporary tracheostomy has been described. Screening for allergic reactions to penicilline is needed, with the risk of anaphylactic shock in mind. It is difficult to compare the different techniques used by the authors, and none of the trials included in this study are randomized controlled trials; most are retrospective and were so-called level 4 studies. This review demonstrates that OK-432 is an effective way to treat LM. Because of a possible risk of airway obstruction, treatment should always take place in specialized treatment facilities. Macrocystic lesions show a better response to OK-432 treatment than microcystic lesions. Serious complications with OK-432 are infrequent, and this type of sclerotherapy seems to have no influence on future surgery. We therefore suggest the use of OK-432 as an effective first-line treatment of LMs.

We conducted a clinical trial of an NY-ESO-1 cancer vaccine using 4 synthetic overlapping long peptides (OLP; peptides #1, 79-108; #2, 100-129; #3, 121-150; and #4, 142-173) that include a highly immunogenic region of the NY-ESO-1 molecule. Nine patients were immunized with 0.25 mg each of three 30-mer and a 32-mer long NY-ESO-1 OLP mixed with 0.2 KE Picibanil OK-432 and 1.25 mL Montanide ISA-51. The primary endpoints of this study were safety and NY-ESO-1 immune responses. Five to 18 injections of the NY-ESO-1 OLP vaccine were well tolerated. Vaccine-related adverse events observed were fever and injection site reaction (grade 1 and 2). Two patients showed stable disease after vaccination. An NY-ESO-1-specific humoral immune response was observed in all patients and an antibody against peptide #3 (121-150) was detected firstly and strongly after vaccination. NY-ESO-1 CD4 and CD8 T-cell responses were elicited in these patients and their epitopes were identified. Using a multifunctional cytokine assay, the number of single or double cytokine-producing cells was increased in NY-ESO-1-specific CD4 and CD8 T cells after vaccination. Multiple cytokine-producing cells were observed in PD-1 (-) and PD-1 (+) CD4 T cells. In conclusion, our study indicated that the NY-ESO-1 OLP vaccine mixed with Picibanil OK-432 and Montanide ISA-51 was well tolerated and elicited NY-ESO-1-specific humoral and CD4 and CD8 T-cell responses in immunized patients.

The treatments previously used for lymphangiomas of the head and neck in children-surgery and intralesional injection of sclerosants-are associated with significant morbidity. A new treatment-intralesional injection of OK-432-was used for lymphangiomas of the head and neck in 11 children. The results were total shrinkage in two, marked shrinkage in two, slight shrinkage in five and no response in two. The results were not affected by previous surgery nor by whether aspiration prior to injection was possible. There were no recurrences in those children in whom shrinkage occurred and no child had subsequent surgery following injection. The results of this series support those of previous series showing that OK-432 injection is an effective and safe treatment for lymphangiomas of the head and neck in children.

Systemic immune responses after OK-432 (Picibanil) sclerotherapy in patients with head and neck lymphatic malformations (LM) were examined to achieve a better understanding of the mechanism of OK-432 sclerotherapy and to evaluate the long-term treatment outcome. Serum samples from 17 consecutive patients with head and neck LMs were collected during a total of 26 OK-432 treatment episodes. Serum C-reactive protein (CRP), interleukins (IL) 1β, 6, 8, 10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, RANTES, immune protein (IP)-10 and macrophage chemoattractant protein (MCP)-1 as well as blood leukocyte counts were determined. Clinical outcome of the treatment was evaluated at the last visit and from patient files. Elevated serum levels of IP-10 (means at baseline 702 ng/L, after 1 day 1180 ng/L, after 4 weeks 691 ng/L) were seen on day one after OK-432 sclerotherapy (p < 0.05). C-reactive protein and leukocyte counts 1 day after treatment differed statistically significantly (p < 0.05) from the baseline. No significant differences with other cytokines investigated were observed. Patients with macrocystic LM responded better than patients with microcystic LM (p = 0.01). The elevated levels of IP-10, C-reactive protein and leukocyte levels indicate that OK-432 sclerotherapy induces systemic immune responses in patients with LM. The mechanisms of OK-432 sclerotherapy are still not precisely understood, but the IP-10 elevation may reflect local antiangiogenetic properties of immunoactivation induced by OK-432.

In general, benign neck cysts are treated by surgical excision. This can present technical difficulties and frequent recurrences, because of insufficient surgery. Sclerosing agents such as OK-432 have been tested for the nonsurgical treatment of these cysts. We have assessed the efficacy of OK-432 sclerotherapy for benign neck cysts. The study group consisted of 75 patients (42 men, 33 women) diagnosed with and treated for benign neck cysts between March 2001 and December 2007 by intralesional injection of OK-432. The liquid content of each cyst was aspirated as much as possible, and the same volume of OK-432 solution was injected. Patients were assessed by ultrasonography or computerized tomography, and therapeutic outcomes and adverse effects were evaluated by patient age, sex, cyst type, and number of injections. Of the 75 treated patients, 31 (41.3%) showed total shrinkage, seven (9.3%) showed near-total shrinkage (>90% of cyst volume), five (6.6%) showed marked shrinkage (>70% of cyst volume), and 17 (22.7%) showed partial shrinkage (<70% of cyst volume). No response was seen in 15 patients (20%). Despite repeated sclerotherapy, eight patients (10.7%) showed recurrences. Minor adverse effects of therapy included fever, localized pain, and odynophagia but these complications spontaneously disappeared within several days. OK-432 sclerotherapy is a safe and effective primary alternative to surgery in patients with benign neck cysts.

Lymphangioma of the tongue is a rare and benign tumour involving congenital and cystic abnormalities derived from lymphatic vessels. Treatment modalities include surgery and a large number of different intralesional injections of sclerosing agents. Presently, OK-432 (Picibanil(®)) is the preferred sclerosant and when administered intralesionally will result in inflammation, sclerosis, and cicatricial contraction of the lesion. We report a case of microcystic lymphangioma of the tongue in a 5-year-old boy treated with an intralesional injection of OK-432. In the immediate postoperative period, the patient suffered severe diffuse swelling, progressive upper airway obstruction with inspiratory stridor, and respiratory distress requiring emergency fiberoptic nasotracheal intubation. Although OK-432 injections are found to be safe and effective as a first line of treatment for lymphangiomas, local swelling with potentially life-threatening airway compromise should be anticipated, especially when treating lesions near the upper airway.

Primary fetal hydrothorax (PFHT) is an uncommon condition with an estimated prevalence of 1 in 10,000/15,000 pregnancies. Therapeutic interventions include thoracocentesis, thoraco-amniotic shunting (TAS), and pleurodesis using OK-432. A review of the literature was performed to identify all cases of PFHT treated with TAS and OK-432. All cases of PFHT referred to the Fetal Maternal Unit at Royal Prince Alfred Hospital between 2002 and 2012 were retrospectively reviewed. In the cohort of fetuses treated with OK-432, the main perinatal outcomes evaluated were termination of pregnancy, live birth, neonatal death, and fetal death in utero. Secondary outcomes included gestational age (GA) at diagnosis, GA at treatment, GA at resolution, birth weight, and GA at birth. The development of the children was screened using the Ages and Stages Questionnaires, Version 3 (ASQ-3, 2009). Primary hydrothorax was diagnosed in 31 fetuses, of which 14 had treatment with OK-432. One pregnancy terminated after treatment with OK-432. Survival was 85% (11/13): 100% in fetuses treated with OK-432 without hydrops, and 78% in those treated with hydrops. This compares well to the cases of TAS in the literature with an average survival of 63%: 85% in fetuses without hydrops and 55% with hydrops. The mean GA at birth was 36(+4) weeks and mean birth weight 3,007 g. Eight of the 9 children screened with ASQ-3 scored well within the normal range. OK-432 appears to be a valid treatment option in fetuses with PFHT, particularly in those diagnosed at early GAs. © 2014 S. Karger AG, Basel.

Postoperative cervical chylous lymphoceles are extremely rare circumscribed collections of lymph which are usually treated by drainage or surgical exploration, but rarely by sclerotherapy. We investigated the efficacy of OK-432 (Picibanil, Chungai Pharmaceutical Co., Tokyo, Japan) sclerotherapy in the treatment of cervical lymphocele after neck dissection. Four patients with postoperative lymphocele who could not be cured by repeated percutaneous needle aspiration and pressure dressing were treated with intralesional injection of 0.1-0.2 mg OK-432 after aspiration of fluid. The aspirated fluid was assessed biochemically and cytologically, and regular palpation and ultrasonography/computed tomography were used to evaluate outcomes and recurrences. Two patients with chyle leak during neck dissection had lymphoceles in the left supraclavicular region 3 weeks later. The other two patients had lymphoceles on the right neck 9 and 12 months, respectively, after neck dissection. All aspirated fluids were chylous in origin without tumor cells. OK-432 sclerotherapy scored all four lesions with no major complications except for fever and local pain for several days. No lymphocele recurrences or metastatic cancers were observed in any patient for >1 year after sclerotherapy. Intralesional injection of OK-432 may be a safe and effective alternative to surgical exploration in the treatment of cervical lymphocele after neck dissection.

Dendritic cells (DCs) are potent antigen-presenting cells. OK432 (Picibanil®) was introduced as a potent stimulator of DC maturation in combination with prostaglandin-E2 and interferon-α. We compared the efficacy of a DC-prostate cancer vaccine using early-mature DCs stimulated with OK432, PGE2 and INF-α (OPA) with that of vaccines using other methods. On days 3 or 7 of DC culture, TNF-α (T), TNF-α and LPS (TL) or OPA were employed as maturation stimulators. DU145 cells subjected to heat stress were hybridized with mature DCs using polyethyleneglycol. T cells were sensitized by the hybrids, and their proliferative and cytokine secretion activities and cytotoxicity were measured. The yields of early-mature DCs were higher, compared to yields at the conventional maturation time (P<0.05). In the early maturation setting, the mean fusion ratios, calculated from the fraction of dual-positive cells, were 13.3%, 18.6%, and 39.9%, respectively (P=0.051) in the T only, TL, and OPA-treated groups. The function of cytotoxic T cells, which were sensitized with the hybrids containing DCs matured early with OPA, was superior to that using other methods. The antitumor effects of DC-DU145 hybrids generated with DCs subjected to early maturation with the OPA may be superior to that of the hybrids using conventional maturation methods. PMID:20808670

The management of lymphangioma using sclerotherapy has proven to be an effective therapeutic. Our aim was to evaluate the therapeutic efficacy of OK-432 (Picibanil) in patients with lymphagioma. The study was performed from November 2010 to July 2011. Fifteen patients of both genders were diagnosed with lymphangioma, 12 days to 12 years old. All patients were infiltrated with OK-432. The studied variables were: previous surgery, localization, type of lymphangioma, number of effective injections, reduction of mass valued as excellent (100% reduction), good (reduction > 50%) and bad (reduction < 50%), presence of recurrence and complications. 40% of pacients had prior surgery and 53.3% were located in the cervical-face region. The type of macrocystic lymphangioma was present in 40% of the series, mixed type in 46.6% and microcystic type in 13.4%. The number of effective infiltrations were 3. In 6 cases (40%) the result was excellent in 5 cases (33.4%) the result was good and in 4 cases (26.6%). We had 1 recurrence (6.6%) and we haven't had complications. Injection of OK-432 in macrocystic lymphangioma and mixed had a safe therapeutic modality with satisfactory results. So it is a valid alternative to conventional surgery.

Picibanil (OK-432) and bleomycin have been used as alternative sclerosing agents for lymphatic malformations. This study evaluated the clinical curative effect of sclerotherapy using fibrin glue combined with OK-432 and bleomycin for the treatment of macrocystic lymphatic malformations of the face and neck. Fifteen paediatric patients (6 males; 9 females, aged 13 months to 14 years) who had received percutaneous sclerotherapy for massive macrocystic lymphatic malformations of the face and neck were retrospectively reviewed. Affected regions included the neck, parotid region and parapharynx, mouth floor, face and cheek, and orbital regions. All patients showed preoperative symptoms of space-occupying lesions between 4 cm × 5 cm and 12 cm × 16 cm in size. Fibrin glue with OK-432 and bleomycin was injected under general anaesthesia. All patients received preoperative and follow-up CT scans. Outcomes were assessed by three surgeons. All patients exhibited mid-facial swelling for 3-4 weeks after surgery, but no major complications. Follow-up periods ranged from 8 to 16 months. Eight lesions were completely involuted, five were mostly involuted, and two were partially involuted. Percutaneous sclerotherapy using fibrin glue with OK-432 and bleomycin provided a simple, safe, and reliable alternative treatment for massive macrocystic lymphatic malformations of the face and neck.

To determine the efficacy and safety of the immunostimulant OK-432 (Picibanil) as a treatment option in the management of children with cervicofacial lymphatic malformations. A prospective, randomized, multi-institutional phase II clinical trial at 27 U.S. academic medical centers. 182 patients with lymphatic malformations (LM) were enrolled between January 1998 and November 2004. Of the 151 patients with complete case report forms, 117 patients were randomized into immediate or delayed treatment groups; 34 patients were nonrandomized and assigned to the open-label group. Treatment consisted of a four-dose intralesional injection series of OK-432 at eight-week intervals. Patients randomized into the delayed treatment group served as observational controls for spontaneous regression. Response to therapy was measured radiographically by quantitating change in lesion size and graded as complete (90%-100%), substantial (60%-89%), intermediate (20%-59%), or none (<20%). Of 117 patients randomized with intent-to-treat, 68% demonstrated a complete or substantial response to OK-432 immunotherapy. Response data for macrocystic LM were higher, with a complete or substantial response in 94% of patients; 63% of patients with mixed macrocystic-microcystic LM responded to treatment; no patients with microcystic LM responded to treatment. Spontaneous resolution occurred in less than 2% of patients. Median follow-up of 2.9 years demonstrated a 9% recurrence rate. Major adverse effects related to therapy occurred in 11 patients. As compared to historical surgical data on LM, OK-432 immunotherapy is more effective (P < .001) and has a lower morbidity (P < .001). OK-432 immunotherapy is an effective, safe, and simple treatment option for the management of macrocystic cervicofacial LM. ClinicalTrials.gov Identifier: NCT00010452.

A ranula is a pseudocyst caused by mucous extravasation from the sublingual gland. Recently, a sclerosing agent, OK-432 (picibanil), has been reported to be highly effective for treating lymphangioma and cervical cystic lesions. The present study assessed the effectiveness of OK-432 injection therapy for intraoral ranula to clarify whether it can be used as the primary treatment. The present study was a retrospective clinical study of patients with intraoral ranula who received OK-432 injection therapy from 2005 to 2015. The ranula size was measured on computed tomography or magnetic resonance imaging studies. We dissolved 1 Klinische Einheit (KE) unit of OK-432 powder in normal saline equal to the aspiration volume. The primary endpoint was the treatment results. The secondary endpoints were the relation between the treatment results and the lesion length and aspiration volume. A total of 23 patients received OK-432 injection therapy for an intraoral ranula. The mean lesion size was 19.96 mm. The mean aspiration volume was 2.14 mL. The number of injections was 1 to 4 (mean 1.70). The treatment results were complete regression (CR) in 18 (78.2%), partial regression (PR) in 3 (13.0%), and no response (NR) in 2 (8%) patients after the last injection. The overall efficacy rate was 91.2% (21 of 23). No serious complications were observed. The lesion length and aspiration volume of the CR group was 17.38 mm and 1.40 mL, respectively. The lesion length and aspiration volume of the PR/NR group was 29.20 mm and 4.80 mL, respectively. The PR/NR group lesions were significantly larger than the CR group lesions. OK-432 injection therapy for intraoral ranula is safe and effective compared with other surgical therapies. This therapy could potentially become a primary treatment of intraoral ranula.

Congenital cystic lymphangiomas are benign malformations due to a developmental disorder of lymphatic vessels. Besides surgical excision, sclerosant therapy of these lesions by intracavitary injection of OK-432 (Picibanil®), a lyophilized mixture of group A Streptococcus pyogenes, is a common therapeutical option. For an appropriate application of OK-432, a detailed knowledge about the structure and composition of the congenital cystic lymphangioma is essential. SonoVue® is a commercially available contrast agent commonly used in sonography by intravenous and intracavitary application. Here we report the case of 2 month old male patient with a large thoracic congenital cystic lymphangioma. Preinterventional imaging of the malformation was performed by contrast-enhanced ultrasound after intracavitary application of SonoVue® immediately followed by a successful sclerotherapy with OK-432. Contrast agent-enhanced ultrasound imaging offers a valuable option to preinterventionally clarify the anatomic specifications of a congenital cystic lymphangioma in more detail than by single conventional sonography. By the exact knowledge about the composition and especially about the intercystic communications of the lymphangioma sclerosant therapy becomes safer and more efficient.

TC-1 cell is a cell line with high expression of E7 antigen of HPV type 16 and its cell lysate has been demonstrated as an ideal inducer of E7-specific, antitumor immunity. OK-432 (Picibanil), a penicillin-killed Streptococcus pyogenes, has been reported with potent immunomodulation properties in cancer treatment by stimulating the maturation of dendritic cells (DCs) and secretion of Th-1 type cytokines. The current study demonstrated that a protocol to immunize the C57BL/6 mice with OK-432 followed by treatment with TC-1 lysate can generate markedly increased immune responses of E7-specific CD4(+) T cells and a moderate increase of natural killer (NK) cell, as well as a satisfactorily protective and therapeutic antitumor effect by triggering the DCs to prime T cells. Depletion of lymphocyte subset in vivo suggested that the antitumor effects could be dominantly executed by CD8+ T cells and followed by NK cells, and both of these reactions were induced by the generation of robust E7-specific CD4(+) T helper cell response. These findings warrant OK-432 combination with tumor-lysate as an effective and safe vaccine in future clinical application of cervical cancer.

The current prospective randomized study was designed to evaluate the safety and efficacy of combined intrapleural cisplatin and OK-432 (picibanil) plus hyperthermotherapy in patients with malignant pleural effusion (MPE). A total of 358 patients with MPE due to end-stage malignancies were enrolled and randomly divided into two groups, A and B: the intrapleural combination of cisplatin and OK-432 with hyperthermotherapy (n = 179) or without hyperthermotherapy (n = 179), respectively. Mild toxicities such as nausea, vomiting or anorexia, bone marrow depression, and pyrexia were similar in both groups. Patients in Group A (with hyperthermotherapy) showed a significantly higher overall response (93.4%) compared to those in Group B (79.8%, χ(2) = 43.11, p < .05). The median survival time for patients in Group A and Group B were 8.9 and 6.2 months, respectively (p > .05). After treatment, the quality of life scores were significantly increased in both groups as compared to prior treatment (p < .05). In conclusion, our study suggests that combined intrapleural cisplatin and OK-432 followed by hyperthermotherapy are more effective in the control of MPE and improve patients' quality of life.

This scoping review assesses the literature and summarizes the current evidence on sclerotherapy for the treatment of lymphatic malformations in pediatric patients. A comprehensive search of published and unpublished literature was conducted using multiple databases. Title, abstract, and full-text screening was conducted by 2 independent clinicians. All discrepancies were resolved during consensus meetings. A total of 182 articles were retrieved. Forty-four articles were removed as duplicates, and 11 articles were added after reviewing prominent studies. After full-text abstraction, 44 articles and 2 conference proceedings (N = 882 patients) were included in the final results. Twelve articles were classified as level II and 34 articles as level IV evidence. Picibanil (OK-432) was the primary agent used in most included studies. Postinjection symptoms with OK-432 were primarily fever, swelling, and erythema at the site. Life-threatening complications were uncommon and involved postinjection swelling of cervical lesions causing airway compromise. The literature regarding sclerotherapy for lymphatic malformations is of a low level of evidence and suffers from a lack of standardization. Randomized clinical trials focused on OK-432, bleomycin, or alcoholic solution of zein; standardized dosing protocols; and consistent and reliable outcome reporting will be necessary for further development of treatment guidelines.

Postoperative hepatic lymphorrhea is a very rare complication after abdominal surgery. Hepatic lymphorrhea, not containing chyle, involves an internal lymph fistula between the lymphatic channels toward the cisterna chyli and the peritoneal cavity. Over the past 20 years, 17 cases have been reported in Japan. Here, we report a further case, of a patient with successfully treated intractable hepatic lymphorrhea following gastrectomy for early gastric cancer. We review 18 cases, including the present case, with respect to the management of postoperative lymphorrhea refractory to conventional medical treatment.

We conducted a phase I clinical trial of a cancer vaccine using a 20-mer NY-ESO-1f peptide (NY-ESO-1 91-110) that includes multiple epitopes recognized by antibodies, and CD4 and CD8 T cells. Ten patients were immunized with 600 μg of NY-ESO-1f peptide mixed with 0.2 KE Picibanil OK-432 and 1.25 ml Montanide ISA-51. Primary end points of the study were safety and immune response. Subcutaneous injection of the NY-ESO-1f peptide vaccine was well tolerated. Vaccine-related adverse events observed were fever (Grade 1), injection-site reaction (Grade 1 or 2) and induration (Grade 2). Vaccination with the NY-ESO-1f peptide resulted in an increase or induction of NY-ESO-1 antibody responses in nine of ten patients. The sera reacted with recombinant NY-ESO-1 whole protein as well as the NY-ESO-1f peptide. An increase in CD4 and CD8 T cell responses was observed in nine of ten patients. Vaccine-induced CD4 and CD8 T cells responded to NY-ESO-1 91-108 in all patients with various HLA types with a less frequent response to neighboring peptides. The findings indicate that the 20-mer NY-ESO-1f peptide includes multiple epitopes recognized by CD4 and CD8 T cells with distinct specificity. Of ten patients, two with lung cancer and one with esophageal cancer showed stable disease. Our study shows that the NY-ESO-1f peptide vaccine was well tolerated and elicited humoral, CD4 and CD8 T cell responses in immunized patients. Copyright © 2011 UICC.

The effects of the anti-tumour agent OK-432 on the immune response to hamster erythrocytes (HRBC) and nucleated chicken erythrocytes (CRBC) were studied in inbred SL mice. Mice were treated repeatedly with OK-432 before immunization with erythrocytes in saline. The cytotoxicity of CRBC-primed spleen cells, as demonstrated by 51Cr release from labelled CRBC, was markedly increased by treatment with OD-432. The delayed footpad reaction to CRBC was significantly augmented by treatment with OK-432. These results in mice indicate that OK-432 can enhance the cellular immune responses which require the contribution of T cells. Such an activation of T cells by OK-432 was observed in the humoral immune response to a trinitrophenyl group. Augmentation of anti-hapten antibody production, suggesting the enhancement of helper T cell activity by OK-432, was noticed after immunization with trinitrophenyl conjugated to erythrocytes. Furthermore, this enhancement of helper T cell activity by OK-432 was confirmed by utilizing an adoptive transfer system. These results support the possibility that T cell activation may be one of the important effects of OK-432 as an immunopotentiator. PMID:314874

To investigate, by a multi-institutional randomized trial, the prognostic significance of the augmentation of tumour-infiltrating lymphocytes (TILs) by preoperative intratumoral injection of OK-432 (OK-432 it), a bacterial biological response modifier, in patients with gastric cancer. The 10-year survival and disease-free survival were examined and analysis of the factors showing survival benefit was performed. 370 patients who had undergone curative resection of gastric cancer were enrolled in this study and followed up for 10 years postoperatively. Patients were randomized into either an OK-432 it group or a control group. Ten Klinishe Einheit (KE) of OK-432 was endoscopically injected at 1 to 2 weeks before the operation in the OK-432 it group. Both groups received the same adjuvant chemoimmunotherapy consisting of a bolus injection of mitomycin C (0.4 mg kg−1i.v.) and administration of tegafur and OK-432 from postoperative day 14 up to 1 year later. Tegafur (600 mg day−1) was given orally and OK-432 (5 KE/2 weeks) was injected intradermally for a maintenance therapy. The TILs grades in resected tumour specimens and presence of metastasis and metastatic pattern in dissected lymph nodes were examined. Multivariate analysis was performed to determine the efficacy of OK-432 it on prognostic factors. All patients were followed up for 10 years. The overall 5- and 10-year survival rates and disease-free survival rates of the OK-432 it group were not significantly higher than those of the control group. However, OK-432 it significantly increased the 5- and 10-year survival rates of patients with stage IIIA + IIIB, moderate lymph node metastasis (pN2), and positive TILs. OK-432 it was most effective at prolonging the survival of patients who had both positive TILs and lymph node metastasis. The OK-432 it group with positive TILs showed a significant decrease in metastatic lymph node frequency and in the number of lymph node micro- metastatic foci when compared to the control group. This study showed that only one time preoperative OK-432 it, particularly when it triggers TILs, is effective for reduction of regional lymph node metastasis. OK-432 it probably acts partly by eliminating micro-metastatic foci in lymph nodes. Preoperative intratumoral injection of OK-432 is technically very easy and has no serious adverse effects, so it is a promising form of neoadjuvant immunotherapy for advanced gastric cancer. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11207036

OK-432, a Streptococcus-derived anticancer immunotherapeutic agent, has been applied in clinic for many years and achieved great progress in various cancers. In the present study, we investigated its anticancer effect on bladder cancer through tumor associated macrophages (TAMs). MTS assay validated OK-432 could inhibit proliferation in both T24 and EJ bladder cell lines. OK-432 also induced apoptosis of bladder cancer cells in vitro. Consequently, we demonstrated that OK-432 could suppress the bladder cancer cells migration and invasion by altering the EMT-related factors. Furthermore, using SD rat model, we revealed that OK-432 inhibited tumor growth, suppressed PCNA expression and inhibited metastasis in vivo. Taken together, these findings strongly suggest that OK-432 inhibits cell proliferation and metastasis through inducing macrophages to secret cytokines in bladder cancer.

Retiform hemangioendothelioma (RH) is a rare low-grade malignancy angiosarcoma, with a high rate of local recurrence and a low metastatic risk. A 6 year-old girl with a large cervical cystic lymphangioma diagnosed by ultrasound and Doppler ultrasound, which showed a large multiloculated anechoic cyst with no flow. The lymphangioma was treated with injections of Picibanil (OK-432). The tumor regressed, but after a year, she developed a poorly limited infiltrated plaque spreading out regularly over her chest, back, and shoulder. The biopsy showed a poorly limited dermal and subcutaneous vascular proliferation composed of elongated arborising vessels lined with ovoid endothelial cells in a hobnail pattern. In addition, the deep part of the lesion showed typical features of a papillary intralymphatic angioendothelioma pattern (PILA) or Dabska tumor. The endothelial cells strongly expressed podoplanin (D2-40). A diagnosis of RH with focal areas of PILA was reached. The girl died 8 months after surgery of hypovolemic shock in a context of diffuse lymphangiomatosis with pulmonary localization. To our knowledge, RH has hardly ever been described in children. This entity exhibits a continuum with the PILA, sharing not only morphological and immunohistochemical similarities but also its ability to develop in a context of a vascular anomaly, particularly a lymphangioma. The role of Picibanil in the development of this tumor can be discussed.

Generation of functional dendritic cells (DCs) with boosted immunity after the withdrawal of initial activation/maturation conditions remains a significant challenge. In this study, we investigated the impact of a newly developed maturation cocktail consisting of OK-432 and interferon-gamma (IFN-γ) on the function of human monocyte-derived DCs (MoDCs). We found that OK-432 plus IFN-γ stimulation could induce significantly stronger expression of surface molecules, production of cytokines, as well as migration of DCs compared with OK-432 stimulation alone. Most importantly, DCs matured with OK-432 plus IFN-γ-induced maintained secretion of interleukin-12 (IL-12)p70 in secondary culture after stimulus withdrawal. Functionally, OK-432 plus IFN-γ-conditioned DCs induce remarkable Th1 and Tc1 responses more effectively than OK-432 alone, even more than the use of α-type-1 cytokine cocktail. As a result, DCs matured with OK-432 plus IFN-γ can prime stronger cytotoxic lymphocyte (CTL) and natural killer (NK) cell response against tumor cells in vitro. Peripheral blood mononuclear cells activated by DCs matured with OK-432 plus IFN-γ also showed greater tumor growth inhibition in vivo in null mice. Molecular mechanistic analysis showed that DC maturation using IFN-γ in concert with OK-432 involves the activation of p38 and nuclear factor-kappa B (NF-κB) pathways. This study provided a novel strategy to generate more potent immune segments in DC vaccine.

The current study was designed to compare the effects of oral administration of the streptococcal preparation, OK-432, as an adjuvant immunotherapy versus those of intradermal administration of OK-432 on the survival of patients after surgery for gastric cancer. The patients were stratified into two groups after surgery: a curative surgery stratum and a palliative surgery stratum. Then the patients in each stratum were randomly assigned into three groups: an oral placebo group, an oral OK-432 group, and an intradermal OK-432 group. All of the patients were given fluoropyrimidines orally in combination with OK-432 or placebo for 2 years after surgery. A total of 1011 patients were registered between 1982 and 1985, and 970 patients were eligible for statistical analysis. The survival rate of the oral OK-432 group was significantly higher than those of the other two groups after curative surgery. There were no significant difference in the survival rates between the three groups after palliative surgery, however. The effect of oral OK-432 was quite pronounced in patients after curative surgery for stage II to IV gastric cancer, especially in those patients with regional node involvement. Furthermore, it was found that the spleen is necessary for effective immunotherapy with oral OK-432, because the survival rate of the oral OK-432 group was significantly improved in patients whose spleens were preserved, when compared with splenectomized patients. These results demonstrate that oral adjuvant immunotherapy with OK-432 is beneficial after curative surgery for gastric cancer. PMID:1632701

Background OK-432, penicillin-killed Streptococcus pyogenes, is used in treating lymphangiomas and carcinomas. We have studied in vitro the role of mononuclear phagocytes (MNPs), including purified monocytes (MOs), in the immune response to OK-432. MIP-1α/β and MCP-1 secretions were assessed in whole blood (WB), peripheral blood mononuclear cells (PBMCs) and purified MOs, after in vitro stimulation with OK-432 with or without adherence for 24 hours. Results OK-432 stimulated MNPs to secrete MCP-1 and MIP-1α/β in healthy individuals and in head and neck squamous cell carcinoma (HNSCC) patients, except for OK-432 stimulation of WB giving a minimal MIP-1α/β response. Upon culture on low-attachment wells, a spontaneous chemokine secretion was observed, with an unchanged secretion following OK-432 stimulation. Inhibition of Syk kinase and/or PI-3 kinase did not significantly change the chemokine response to OK-432, except for MIP-1α production being increased upon Syk inhibitor addition and an increased MCP-1 response upon addition of both inhibitors. Adhesion may possibly involve β1 and/or β3 integrins, not β2, whereas β1–3 integrins may act as co-stimulatory receptors for OK-432. Based on direct blockage of CD36 or CD18 by antibodies, MCP-1 production may be mediated by CD18 while MIP-1β and MCP-1 production may occur upon binding to CD36. Conclusion Adherent human MOs produce MCP-1 and MIP-1α/β upon stimulation with OK-432. CD36 modulates MIP-1β and MCP-1 response. Thus, to some extent OK-432 acts as a substance whereby only MOs adhered to surfaces secrete MCP-1 and MIP-1α/β, in part explaining why OK-432 is suited as a biological response modifying drug.

A variety of sclerotherapy agents are used to treat macrocystic lymphatic malformations (LMs). This retrospective study at a single institution was performed to compare the outcomes of pediatric macrocystic LMs of the head and neck that were treated with doxycycline or with OK432. The outcomes measured included early response to therapy, number of treatments required, operating room time, and adverse events. The rates of clinical success for OK432 and doxycycline were similar (83% and 82%, respectively; p > 0.05), although OK432-treated patients required more treatments than did doxycycline-treated patients (1.9 versus 1.0 injections; p = 0.01; 95% confidence interval, 1.57 to 0.27). The average operating room time for a single OK432 injection was significantly shorter than that for doxycycline (53.2 versus 98.1 minutes; p < 0.001); however, when the total number of treatments administered was considered, the overall times in the operating room were similar. Adverse events in the early postoperative period were more common in OK432-treated patients, who experienced marked postoperative swelling compared to doxycycline-treated patients. OK432 and doxycycline are both effective sclerosants for the treatment of predominantly macrocystic LMs. The administration time for OK432 is shorter than that for doxycycline, but OK432 required more treatments overall to achieve clinical success. Early adverse events were more common in OK432-treated patients, but longer follow-up is necessary to determine whether rates of recurrence and adverse events are similar, particularly in light of the risk of tooth discoloration in doxycycline-treated patients.

Purpose/aim: Modified radical mastectomy is the standard surgery for breast cancer in developing countries. However, seroma formation regarded as the most frequent postoperative complication limits the therapeutic benefit of mastectomy and axillary surgery. The purpose of this study was to evaluate the efficacy of OK-432 in reducing seroma formation after axillary dissection. This prospective cohort study included 80 patients with advanced breast cancer who underwent modified radical mastectomy. Patients were randomized into two groups, which differed with the OK-432 administration. N = 40 patients per group were treated with either OK-432 plus closed suction drainage or drainage-only. In comparison with the drainage-only group, we found that patients in the OK-432 group had a lower drainage volume (p = .030) and a shorter duration of axillary drainage (p < .01). Besides, the use of OK-432 could reduce the incidence of seroma formation (p < .01) and the volume of seroma (p = .040). There were also significant differences in reducing the chance of evacuative punctures (p = .036) and the healing time (p < .01) between control and OK-432 group. OK-432 not only shortened the suction drainage duration, but also significantly reduced seroma formation as well as the needs for aspiration punctures after modified radical mastectomy.

To define the changes in the pleural cavity after pleurodesis induced by talc or OK-432. A total of 30 rats were divided into three groups: a normal saline group (control group, n = 10), a group administered 400 mg/kg talc (talc group, n = 10), and a group administered 0.3 KE/kg OK-432 (OK-432 group, n = 10). Pleural cavities were examined and scored on the 30th day after the intrapleural administration of each agent. Both the talc group and OK-432 group showed significantly higher macroscopic or microscopic pleurodesis scores than the control group (P < 0.05). Upon microscopic evaluation, the pleurodesis scores in the talc group were significantly higher than those in the OK-432 group (P < 0.01).The majority of the pleural thickness was found on the visceral pleura, and the parietal pleura was very thin. The thickness of the visceral pleura in the talc group was significantly higher than that in the OK-432 group (P < 0.005). Pathologically, the pleural thickening in the talc group consisted of fibrous tissue with injury of the pleural mesothelium, and talc particles were seen in the submesothelial fibrotic tissue and inside the alveoli. Talc pleurodesis induces more marked changes in the pleural cavity than OK-432-induced pleurodesis.

Our results confirmed that OK-432 therapy is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of benign neck cysts. In OK-432 therapy, inflammatory cytokines may play important roles in shrinkage of the cystic spaces. The aim of this study was to evaluate the outcome and mechanism of action of OK-432 therapy in benign neck cysts. We tried OK-432 therapy in 83 patients with benign neck cysts between April 1997 and August 2009. We aspirated as much of the fluid content of each cystic lesion as possible, and then replaced the volume of aspirated fluid with about half the volume of OK-432 solution. We evaluated the mechanism of action of OK-432 in 43 of the patients. The intracystic fluid in the cysts was aspirated before and after OK-432 therapy, and cytokine production in each aspirate was analyzed by ELISA. Disappearance of the lesion was observed in 63 of 83 patients (76%). Marked reduction was observed in 13 of the 83 patients (16%). Partial reduction was observed in two patients (2%) and no response was seen in five (6%). Local discomfort at the injection site and low-grade fever were side effects observed in half of the patients, but such problems resolved within a few days. No local scarring or deformity of the injected sites occurred in any patient. We performed OK-432 therapy on an outpatient basis without hospitalization. Levels of various cytokines, including tumor necrosis factor, interleukin-8, interleukin-6, interferon gamma, and vascular endothelial growth factor, were significantly elevated in each aspirate after OK-42 therapy.

Eighty-one patients with oral squamous cell carcinoma (OSCC) received oral fluoropyrimidine UFT and radiotherapy (RT) with or without an immunotherapeutic agent OK-432. Both overall survival and progression-free survival of patients who received RT + UFT + OK-432 were significantly longer than those of patients who received RT + UFT (P = .0075 and P = .0175, respectively). Clinical response was also more favorable in RT + UFT + OK-432 group than in RT + UFT group (P = .0066). Next, in vitro experiments were conducted to examine the effect of 5-fluorouracil (5-FU) and X-ray irradiation in OK-432-induced immunity. Human peripheral blood mononuclear cells stimulated with OK-432 produced helper T cell 1 (Th1)-type cytokines as well as interleukin-10 (IL-10) and transforming growth factor-β (TGF-β), which are produced by Th2 and regulatory T cells (Tregs), respectively, and are inhibitory in antitumor immunity. OK-432-induced IL-10 and TGF-β but not Th1 cytokines were significantly inhibited by 5-FU and/or X-ray. 5-FU and X-ray also inhibited the expression of mRNAs for GATA-3 and Foxp3, which are transcription factors for Th2 and Tregs, respectively, but not for T-bet, a transcription factor for Th1. In addition, 5-FU and X-ray decreased the expression of mRNAs for suppressor of cytokine signaling 1 (SOCS1) and SOCS3. Antisense oligonucleotides for SOCS1 and SOCS3 markedly reduced OK-432-induced IL-10 and TGF-β. This is the first report clearly demonstrating that OK-432-based immunotherapy significantly enhanced the therapeutic effects of chemoradiotherapy in patients with OSCC as well as elucidating the mechanism of the synergistic effect of immunochemoradiotherapy in which 5-FU and radiation enhanced OK-432-induced Th1 response mediated by the inhibition of SOCS1 and SOCS3 gene expression.

OK432, an effective adjuvant, was mixed with viable human umbilical vein endothelial cells (HUVECs) to prepare a novel HUVECs-OK432 vaccine, which could have an improved therapeutic efficacy. In this study, HUVECs-OK432 was administrated in mice by subcutaneous injection in a therapeutic procedure. The results showed that a stronger HUVEC-specific Abs and cytotoxic T lymphocyte immune response were elicited, which resulted in significant inhibition on the growth of B16F10 melanoma and remarkably prolonged survival of B16F10 melanoma-bearing mice compared with HUVECs. Besides, parallel results were obtained in vitro showing a stronger inhibition of HUVEC proliferation by immune sera of HUVECs-OK432 than that of HUVECs. Moreover, histochemistry and immunohistochemistry analysis showed that HUVECs-OK432 induced large areas of continuous necrosis within tumors and significantly reduced the vessel density, correlating well with the extent of tumor inhibition. Our present results suggest that OK432 could be employed as an effective adjuvant for HUVEC vaccines and therefore should be useful for adjuvant immunotherapy of cancer.

The streptococcal antitumor agent OK-432 is commonly used as an immunopotentiator for immunotherapy in various types of malignant tumors including oral cancer. It has been demonstrated that OK-432 elicits an antitumor effect by stimulating immunocompetent cells, thereby inducing multiple cytokines including interferon (IFN)-γ, interleukin (IL)-2 and IL-12. Serum concentrations of IFN-γ in patients with oral cancer were examined 24 h after administration of OK-432. Serum concentrations of IFN-γ in patients with advanced cancer were significantly lower than those in patients with early cancer. These results suggested that some soluble factors produced by cancer cells may inhibit IFN-γ production with OK-432. Thus, in the present study, an in vitro simulation model was established for the immune status of patients with oral cancer by adding conditioned medium (CM) derived from oral cancer cell lines into a culture of peripheral blood mononuclear cells (PBMCs) derived from a healthy volunteer. We investigated whether soluble factors derived from oral cancer cells affected IFN-γ production from PBMCs following stimulation with OK-432. PBMCs stimulated with OK-432 produced a large amount of IFN-γ; however, both IFN-γ production and cytotoxic activity from PBMCs induced by OK-432 were inhibited by the addition of CM in a dose-dependent manner. In order to examine these inhibitory effects against IFN-γ production, the contribution of inhibitory cytokines such as IL-4, IL-6, IL-10, transforming growth factor-β and vascular endothelial growth factor was investigated. However, neutralization of these inhibitory cytokines did not recover IFN-γ production inhibited by CM. These results indicated that unknown molecules may inhibit IFN-γ production from PBMCs following stimulation with OK-432.

Herein, the authors aim to describe their findings of novel architectural types of lymphatic malformations (LM) and explain the relationship between these architectures and OK-432 treatment outcomes. A retrospective review was conducted of all patients diagnosed with a LM treated with OK-432 at the Vascular Anomalies Clinic at BC Children's Hospital from December 2002 to January 2012. Twenty-seven patients were included in the study. Sixty percent of lesions were present by 2 years of age with the majority located in the head and neck (59%). The average number of sclerotherapy procedures was 1.4 per patient. Treatment under fluoroscopic guidance revealed 3 new LM architectures: open-cell microcystic, closed-cell microcystic, and lymphatic channel. Response to treatment was complete or good for 14/19 macrocystic and for 1/2 mixed lesions. Open-cell microcystic LMs gave a complete or good response for 3/3, which was attributed to OK-432 freely communicating between cysts. Closed-cell microcystic LM had localized cysts that did not allow OK-432 to freely communicate and were associated with partial responses, 2/2. The lymphatic channel had a partial response. There were 2 minor complications and 1 instance of recurrence. The identification of 3 new LM architectures expands the current accepted classification to include: open-cell microcystic, closed-cell microcystic, and lymphatic channels. The majority of complete responses to OK-432 were found with macrocystic lesions. Open-cell microcystic lesions respond better to OK-432 than closed-cell microcystic lesions, and lymphatic channels may respond to OK-432. These key architecture-response relationships have direct clinical implications for treatment with OK-432 sclerotherapy.

No previous study to the best of our knowledge has examined the multiple factors related to the outcome of OK-432 sclerotherapy of lymphatic malformations. This study aimed to assess factors related to the successful outcome of OK-432 sclerotherapy for lymphatic malformations in the head and neck region. During a 6-year period, OK-432 sclerotherapy was performed in 26 patients with lymphatic malformations. Several factors related to the efficacy of OK-432 sclerotherapy were evaluated, including the type (macrocystic or microcystic), the maximum lesion diameter, amount and hemorrhagic cytology of the aspirate, degree of aspiration, injected dose of OK-432 and post-therapy inflammation-related symptom. In all cases, ultrasound (US) follow-up was performed. Of the 26 cases, 13 (50%) showed successful elimination of the lymphatic malformations in the follow-up US after the initial session, and all successful cases were of the macrocystic type. The type of lymphatic malformation and the success of OK-432 sclerotherapy were significantly related (P = 0.0149). Of the 16 cases of complete aspiration, 11 (68.8%) showed a successful outcome. Further, of the 17 cases with inflammation-related symptom, 13 (76.5%) showed a successful outcome. While the degree of aspiration and presence of inflammation-related symptom showed a significant relationship with the success of OK-432 sclerotherapy (P < 0.05), no other factors showed a significant relationship. The study results suggest that the macrocystic type and complete aspiration of cystic contents were important factors for the success of OK-432 sclerotherapy of lymphatic malformations, and that inflammation-related symptom was a predictor of a successful outcome.

Most dendritic cell (DC)-based vaccines have loaded the DC with defined antigens, but loading with autologos tumor-derived antigens would generate DCs that activate personalized tumor-specific T-cell responses. We hypothesized that DC matured with an optimized combination of reagents and loaded with tumor-derived antigens using a clinically feasible electroporation strategy would induce potent antitumor immunity. We first studied the effects on DC maturation and antigen presentation of the addition of picibanil (OK432) to a combination of zoledronic acid, tumor necrosis factor-α, and prostaglandin E2. Using DC matured with the optimized combination, we tested 2 clinically feasible sources of autologous antigen for electroloading, total tumor mRNA or total tumor lysate, to determine which stimulated more potent antigen-specific T cells in vitro and activated more potent antitumor immunity in vivo. The combination of tumor necrosis factor-α/prostaglandin E2/zoledronic acid/OK432 generated DC with high expression of maturation markers and antigen-specific T-cell stimulatory function in vitro. Mature DC electroloaded with tumor-derived mRNA [mRNA electroporated dendritic cell (EPDC)] induced greater expansion of antigen-specific T cells in vitro than DC electroloaded with tumor lysate (lysate EPDC). In a therapeutic model of MC38-carcinoembryonic antigen colon cancer-bearing mice, vaccination with mRNA EPDC induced the most efficient anti-carcinoembryonic antigen cellular immune response, which significantly suppressed tumor growth. In conclusion, mature DC electroloaded with tumor-derived mRNA are a potent cancer vaccine, especially useful when specific tumor antigens for vaccination have not been identified, allowing autologous tumor, and if unavailable, allogeneic cell lines to be used as an unbiased source of antigen. Our data support clinical testing of this strategy.

The streptococcal preparation OK432 was studied for its effects on natural killer (NK) activity of peripheral blood lymphocytes (PBL) from normal donors and from ovarian cancer patients, and of tumour-associated lymphocytes (TAL) from peritoneal effusions. OK432 augmented NK activity against the susceptible K562 line and induced killing of the relatively resistant Raji line. Freshly isolated ovarian carcinoma cells were relatively resistant to killing by unstimulated PBL and TAL. OK432 induced significant, though low, levels of cytotoxicity against 51Cr-labelled ovarian carcinoma cells. Augmentation of killing of fresh tumour cells by OK432 was best observed in a 20 h assay and both autologous and allogeneic targets were lysed. PBL were separated on discontinuous Percoll gradients. Unstimulated and OK432-boosted activity were enriched in the lower density fractions where large granular lymphocytes (LGL) and activity against K562 were found. Thus, OK432 augments NK activity of PBL and TAL in human ovarian carcinomas and induces low, but significant, levels of killing of fresh tumour cells. Effector cells involved in killing of fresh ovarian tumours copurify with LGL on discontinuous gradients of Percoll. PMID:6626452

A decrease in natural killer (NK) cell function has been related to the progression of human immunodeficiency virus (HIV) infection. In the present study, we assessed the ability of a streptococcus-derived biologic response modifier, OK-432, to augment NK lysis of uninfected K562 and U937 cells and HIV-infected U937 cells by peripheral blood mononuclear cells (PBMC) from HIV-seropositive homosexual men. Optimal two- to fourfold increases in lysis of the three targets were observed after pretreatment of PBMC from HIV-negative subjects for 4 h with 2 micrograms of OK-432 per ml. This effect was related primarily to gamma interferon (IFN-gamma) production induced by OK-432 and was not linked to production of tumor necrosis factors alpha and beta or to monocytes in the cultures. The enhancing effect of OK-432 on NK cell function was diminished but still evident in PBMC from subjects with relatively early-phase (< 3-year) HIV infection and high CD4+ cell counts and was lower in subjects with longer-term HIV infection (> 3 years), in association with reduced production of IFN-gamma. Augmentation of NK cell activity in HIV-infected men by OK-432 was comparable to that induced by treatment of cells with 1,000 U of IFN-alpha or interleukin 2 per ml. The data suggest that the NK cell-enhancing effects of OK-432 are at least in part mediated by IFN-gamma and that OK-432 may be effective in treatment of patients with early-phase HIV infection.

Interaction between the immune system and cancer cells allows for the use of biological response modifiers, like OK-432, in cancer therapy. We have studied the involvement of monocytes (MOs) in the immune response to OK-432 by examining MCP-1, MIP-1α and MIP-1β secretion, in vitro. OK-432-induced IL-6/TNF-α secretion has previously been shown to depend on mitogen-activated protein kinases (MAPKs) ERK1/2 and p38, and we therefore investigated the role of these MAPKs in OK-432-induced chemokine secretion. Here we demonstrate that pharmacological MEK1/2 kinase inhibition generally impaired chemokine secretion from MOs, whereas p38 MAPK inhibition in particular reduced MIP-1α production. Furthermore, simultaneous inhibition of MEK1/2 and Syk kinase was seen to have an additive impact on reduced MCP-1, MIP-1α and MIP-1β secretion. Based on single cell flow cytometry analyses, OK-432, lipoteichoic acid (LTA) and lipopolysaccharide (LPS) were seen to induce p38 MAPK and NF-κB phosphorylation in MOs with different time kinetics. LTA and LPS have been shown to induce ERK1/2 phosphorylation, whereas the levels of phosphorylated ERK1/2 remained constant following OK-432 treatment at the time points tested. Toll-like receptors (TLRs) recognize pathogen-associated molecular patterns, and we demonstrate increased TLR2 cell surface levels on the MO population, most profoundly following stimulation with LTA and OK-432. Together these results indicate that modulation of MEK1/2 and p38 MAPK signalling could affect the response to OK-432 treatment, having the potential to improve its therapeutic potential within cancer and lymphangioma treatment. © 2012 The Authors APMIS © 2012 APMIS.

Minimally invasive therapies, such as microwave ablation (MWA), are widely used for the treatment of solid tumors. Previous studies suggest that MWA is feasible for the treatment of small breast cancer, and thermal ablation may induce adaptive antitumor immunity. However, the induced immune responses are mostly weak, and the immunomodulation effects of MWA in breast cancer are unclear. Immunostimulant OK-432 can induce tumor-specific T-cell responses and may augment the immunity induced by MWA. We treated 4T1 breast cancer bearing BALB/c mice with MWA, OK-432, MWA plus OK-432, or left without treatment. Survival time was evaluated with the Kaplan-Meyer method comparing survival curves by log-rank test. On day 25 after ablation, surviving mice received tumor rechallenge, and the rechallenged tumor volumes were calculated every 5 days. Immunohistochemistry and flow cytometry were used to evaluate the T-cell immune responses in ablated tissues and spleens. The tumor-specific immunity was assessed by enzyme-linked immunospot assays. Besides, the cytokine patterns were identified from enzyme-linked immunosorbent assay. Microwave ablation plus OK-432 resulted in longer survival than single treatment and protect most surviving mice from tumor rechallenge. Both local and systemic T-cell responses were induced by MWA and were further enhanced by subsequent administration of OK-432. Moreover, the combination of MWA and OK-432 induced stronger tumor-specific immune responses than MWA alone. In addition, OK-432 and MWA synergistically promoted the production of Th1-type but not Th2-type cytokines, and polarized T-cell responses to Th1-dominant state. The T-cell immune responses were activated by MWA in breast cancer. Furthermore, the combination of MWA and OK-432 induced Th1-type response and elicited specific antitumor immunity.

Maturation of monocyte derived dendritic cells with OK432 boosts IL-12p70 secretion and conveys strong T-cell responses

2011-01-01

Background Design of tumour specific immunotherapies using the patients' own dendritic cells (DC) is a fast advancing scientific field. The functional qualities of the DC generated in vitro are critical, and today's gold standard for maturation is a cytokine cocktail consisting of IL-1β, IL-6, TNF-α and PGE2 generating cells lacking IL-12p70 production. OK432 is an immunotherapeutic agent derived from killed Streptococcus pyogenes that has been used clinically to treat malignant and benign neoplasms for decades. Methods In this study, we analysed the effects of OK432 on DC maturation, DC migration, cytokine and chemokine secretion as well as T-cell stimulatory capacity, and compared it to the cytokine cocktail alone and combinations of OK432 with the cytokine cocktail. Results OK432 induced a marked up-regulation of CD40 on the cell surface as well as a strong inflammatory response from the DC with significantly more secretion of 19 different cytokines and chemokines compared to the cytokine cocktail. Interestingly, secretion of IL-15 and IL-12p70 was detected at high concentrations after maturation of DC with OK432. However, the OK432 treated DC did not migrate as well as DC treated with cytokine cocktail in a transwell migration assay. During allogeneic T-cell stimulation OK432 treated DC induced proliferation of over 50 percent of CD4 and 30 percent of CD8 T-cells for more than two cell divisions, whereas cytokine cocktail treated DC induced proliferation of 12 and 11 percent of CD4 and CD8 T-cells, respectively. Conclusions The clinically approved compound OK432 has interesting properties that warrants its use in DC immunotherapy and should be considered as a potential immunomodulating agent in cancer immunotherapy.

Prolonged air leak is the most common complication after thoracoscopic operation for primary spontaneous pneumothorax (PSP), and the role of chemical pleurodesis in treating air leaks remains unclear. This study evaluated the safety and efficacy of chemical pleurodesis with a comparison between minocycline and OK-432. Between 1994 and 2011, 1083 PSP patients were treated by thoracoscopic operation. After the operation, patients with persistent air leak for 3 days or more were managed by minocycline or OK-432 pleurodesis. The demographic and outcome data for these patients were collected by retrospective chart review. Seventy-nine patients (7.3%) with prolonged air leak after thoracoscopy underwent minocycline pleurodesis (60 patients) or OK-432 pleurodesis (19 patients) as the primary treatment. The primary success rate was 63% (38/60) for minocycline pleurodesis and 95% (18/19) for OK-432 pleurodesis (p = 0.009). Postpleurodesis pain was common and comparable between the two groups. No major complications were noted after a total of 121 treatments. Patients undergoing primary OK-432 pleurodesis had shorter durations of postpleurodesis chest drainage (mean 8.5 vs. 2.3 days; p < 0.001) and postoperative hospital stay (mean 11.9 vs. 6.8 days; p < 0.001) than those undergoing primary minocycline pleurodesis. After a median follow-up of 16 months, recurrence was noted in one patient in the OK-432 group and none in the minocycline group. Long-term pulmonary function in the two groups was comparable. Chemical pleurodesis using OK-432 or minocycline is safe and convenient for prolonged air leak after thoracoscopic treatment for PSP. Our experience suggested that OK-432 may be more effective than minocycline in reducing air leak. Copyright © 2013. Published by Elsevier B.V.

OK-432 is an immunomodulator that has been reported to be efficacious as an injection therapy for cervical lymphomas and ranulas. We performed OK-432 injection therapy to treat a cystadenocarcinoma of the parotid gland in a 72-year-old man. The 50 × 46-mm tumor was located in the deep lobe of the gland. The tumor had compressed the glossopharyngeal, vagus, and hypoglossal nerves, causing neurally mediated syncope, hoarseness, dysphagia, and dysarthria. A concentration of 5 KE/2 ml of OK-432 was injected. Within 2 months, the cyst had disappeared; no recurrence was apparent during 59 months of follow-up. To the best of our knowledge, no previous report has described injection of OK-432 for malignant cystic disease. We describe the injection method, injection dose, and postinjection course in the hope that this information will prove useful for future applications against malignant cystic disease.

The mechanism of anti-tumor effect of transarterial Immuno-Embolization (TIE) using OK-432 has not been well elucidated. In this study, we aimed to investigate the tissue injury and immune response after portal venous embolization (PVE) with/without OK-432. Embolic materials (L group: lipiodol, LF group: lipiodol+fibrinogen, LO group: lipiodol+OK-432, LFO group: lipiodol+fibrinogen+OK-432) were administered via the right portal vein in Wistar rats. The histological findings in LFO group demonstrated liver damage with severe architectural changes. The concentrations of CD68(+) cells were observed in a time-dependent manner; it was significantly increased in the LO group on day 1 and in the LFO group on day 3. CD68(+)CD163(-) macrophages significantly increased in the LFO group on day 7 (P<0.05). In conclusion, PVE with fibrinogen and OK-432 markedly increased the CD68(+)CD163(-) infiltrating macrophages around the peri-portal area in the liver. This novel technique could be applied as immune-enhanced chemo-embolization of liver tumors. Copyright © 2016 Elsevier Inc. All rights reserved.

AIM—To treat orbital lymphangioma with an intralesional injection of OK-432 (group A Streptococcus pyogenes of human origin).
METHOD—A 14 year old boy had a right orbital cystic lymphangioma. The visual acuity in the eye was 20/28. In an initial treatment, 0.02 mg of OK-432, was injected into the tumour after aspiration of the fluid contents, but no effect was seen. The second treatment was performed with 0.04 mg of OK-432.
RESULT—4 months later, the lesion had totally shrunk to fibrous tissue. The side effects were fever, a local inflammatory reaction lasting 3 days, and increased intraocular pressure, which was managed by draining the fluid contents. Visual acuity improved to 20/15, and the visual field defect and restriction of eye movement seen before treatment disappeared. No recurrence was noted 1 year after treatment.
CONCLUSION—An intralesional injection of OK-432 shrunk the lymphangioma without functional disturbance and scar in the facial skin. OK-432 may be useful for orbital lymphangioma, but further studies are still warranted to determine efficacy, complications, and the optimal dose for safe treatment.

In patients with refractory pleural effusion or pneumothorax, fever and elevated level of white blood cell count (WBC) are frequently observed after chemical pleurodesis with intrapleural injection of OK-432, which make it difficult to differentiate whether it was from the side effects of OK-432 or concurrent bacterial infection. Procalcitonin (PCT) levels were measured before and after pleurodesis so as to discuss whether PCT is useful for distinguishing between the side effects of OK-432 and concurrent bacterial infection. Twenty-six patients with refractory pleural effusion or pneumothorax who underwent chemical pleurodesis with intrapleural injection of OK-432 at the First Affiliated Hospital of Sun Yat-sen University between August 2010 and August 2012 were included in our study. Levels of PCT and WBC were measured before and after pleurodesis. Of all 26 patients, 22 patients were with refractory pleural effusion, and the other four were with pneumothorax. The median serum levels of PCT and WBC elevated from 0.155 to 1.470 ng/mL (P = 0.009) and from 5.920 to 10.475 × 10(9) /L (P = 0.000), respectively. No patient was given antibiotics and fever subsided. Intrapleural injection of OK-432 could increase the serum level of PCT and WBC with no bacterial infection. The serum PCT level may not be useful to distinguish whether fever was caused by the side effects of OK-432 or concurrent bacterial infection. © 2013 John Wiley & Sons Ltd.

The aim of this study was to evaluate the indications for, and outcomes and limitations of, OK-432 therapy in various otolaryngological cystic diseases. A retrospective clinical study at Yamagata University School of Medicine and the Fukase Clinic in Japan. Between April 1996 and November 2009 we tried OK-432 therapy in 148 patients with otolaryngological cystic diseases. In cases of plunging ranulas, lymphangiomas, branchial cleft cysts, thyroglossal duct cysts, thyroid cysts, and cervical lymphocele, we aspirated as much of the fluid content of each cystic lesion as possible, and we then replaced the volume of aspirated fluid with about half the volume of OK-432 solution. Disappearance of the lesion was observed in 119 of 148 patients (80%). Marked reduction was observed in 20 of 148 patients (14%). Partial reduction was observed in four patients (3%), and no response was seen in five patients (3%). Plunging ranula, lymphangioma, thyroglossal duct cyst, thyroid cyst, auricular hematoma, and salivary mucocele showed better responses to OK-432 therapy than did branchial cleft cyst. Serious complications with OK-432 therapy were infrequent, and the therapy seemed to have no influence on future surgery. Our results confirmed that OK-432 therapy is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of various otolaryngological cystic diseases.

The intrathoracic administration of OK-432, a lyophilized preparation of the heat- and penicillin-treated Su-strain of type 3, group A Streptococcus pyogenes, is performed in Japan for pleurodesis of malignant pleural effusion or pneumothorax. Persistent fever is often observed after pleurodesis. To elucidate whether procalcitonin (PCT) is useful for distinguishing between the side effects of OK-432 and infection, we measured the serum PCT levels before and after pleurodesis. We performed a prospective study of 12 patients with refractory pleural effusion or pneumothorax who required pleurodesis using OK-432 between August 2011 and February 2012. The serum PCT and C-reactive protein (CRP) levels were measured on days 1 and 3. Of the 12 patients, five had pneumothorax and seven had uncontrolled pleural effusion with carcinomatous pleurisy. The median serum levels of PCT and CRP increased from 0.055 to 1.59 ng/mL (p=0.0022) and from 1.52 to 16.82 mg/dL (p=0.0022), respectively. The fevers subsided without antibiotic administration. The serum PCT level may not be useful for distinguishing fever caused by side effects of OK-432 from that caused by bacterial infection. The intrathoracic administration of OK-432 increased the serum levels of both PCT and CRP in the absence of any bacterial infection.

OK-432 has been used as a cancer treatment for 40 years, and the immunostimulatory effects of OK-432 therapy have been intensely investigated in Japan. Recently, it has received attention as a possible booster for cancer vaccine treatments. Our previous meta-analysis based on summary measures revealed a significant improvement in the survival of patients with curatively resected gastric cancer. However, it is impossible to exclude the possibility of bias due to several prognostic factors. We collected individual data for patients with stage III or stage IV gastric cancer after curative resection from 14 trials that were identified in a previous meta-analysis. Immunochemotherapy with OK-432 was compared with treatment with standard chemotherapy on an intention-to-treat basis. The primary end point was overall survival. Stratified survival analyses were performed with the trial as the stratification factor. Subgroup analyses were also performed according to the potential prognostic factors, which included pathological factors, splenectomy, and delayed-type hypersensitivity. There were 796 and 726 patients in the OK-432 and control groups, respectively. The median overall survival was 42.6 months for the OK-432 group and 32.3 months for the control group. The overall hazard ratio was 0.88 (95 % confidence interval 0.77-1.00, p = 0.050). No factor showed a statistically significant interaction in the subgroup analyses. The results suggest that immunochemotherapy treatment with OK-432 could have a borderline significant effect for patients with stage III or stage IV gastric cancer after curative resection.

We investigated the efficacy of the streptococcal preparation OK-432 as an adjuvant for in vivo priming in induction of sensitized cells for adoptive immunotherapy of the poorly immunogenic B16-BL6 (BL6) melanoma. C57BL/6 (B6) mice were immunized subcutaneously (s.c.) with 3 x 10(6) viable BL6 tumor cells admixed with various doses of OK-432 ranging from 1 to 100 micrograms in the foot-pad. Draining popliteal lymph nodes (LNs) were harvested 7 days after immunization and LN cells were further sensitized with irradiated tumor cells in the presence of 60-300 IU/ml of IL-2 for 11 days. These in vitro sensitized (IVS) cells (2 x 10(6)) were transferred intravenously (i.v.) to B6 mice bearing 4-day pulmonary metastases established by i.v. injection of 2-4 x 10(5) viable BL6 cells. The mice were also received intraperitoneally (i.p.) 4 x 10(4) IU/day of IL-2 for 4 days after adoptive transfer. Transfer of IVS cells from mice immunized by s.c. injection of tumor cells admixed with 10 micrograms of OK-432 significantly reduced the numbers of BL6 pulmonary metastases compared with that of control IVS' cells without the administration of OK-432 (P = 0.003). These effective IVS cells also significantly prolonged the survival of treated animals (P = 0.003). Functional IVS cells required in vitro stimulation with tumor cells. However, addition of OK-432 in the vaccine resulted in no enhancement of in vitro cytotoxicity and no characteristic change of phenotype of IVS cells. These results suggest that in vivo priming of OK-432 facilitates the sensitization of tumor-reactive T-cells. The procedure of in vivo priming with OK-432 may be beneficial in the adoptive immunotherapy of melanoma.

To evaluate whether antitumor immunity is enhanced systemically by combining radiofrequency ablation (RFA) and local injection of an immunostimulant, OK-432. Experiments were approved by the institutional animal care committee. Experimental Japanese rabbits inoculated with VX2 tumors in the lung and the auricle were randomized into four groups of eight: control (supportive care), RFA (RFA of lung tumor), OK-432 (direct injection of OK-432 into lung tumor), and combination therapy (lung RFA and direct OK-432 injection into lung tumor). All procedures were performed 1 week after implantation of VX2 tumors (week 1). In addition, a VX2 tumor rechallenge test was performed in the RFA and combination therapy groups. Survival time was evaluated by means of the Kaplan-Meier method and by using the log-rank test for intergroup comparison. Mean auricle tumor volumes were calculated every week. Specific growth rates (SGRs) were calculated and compared by using the Mann-Whitney test. The median survival times of the control, RFA, OK-432, and combination therapy groups were 23, 36.5, 46.5, and 105 days, respectively. Survival was significantly prolonged in the combination therapy group when compared with the other three groups (P <.05). The mean auricle tumor volume decreased only in the combination therapy group. The mean auricle tumor volumes of the combination therapy group from week 1 to week 7 were 205, 339, 264, 227, 143, 127, and 115 mm(3). SGR in the combination therapy group became significantly smaller than those in the other three groups (P < .05). In the rechallenge test, the volume of all reimplanted tumors decreased. Combining RFA with local injection of immunostimulant OK-432 may lead to indirectly activation of systemic antitumor immunity. © RSNA, 2013.

Fetal exposure to inflammatory mediators is associated with a greater risk of brain injury and may cause endothelial dysfunction; however, nearly all the evidence is derived from gram-negative bacteria. Intrapleural injections of OK-432, a killed Su-strain of Streptococcus pyogenes, has been used to treat fetal chylothorax. In this study, we evaluated the neural and cardiovascular effects of OK-432 in preterm fetal sheep (104 ± 1 days, term 147 days). OK-432 (0.1 mg, n = 6) or saline vehicle (n = 7) was infused in the fetal pleura, and fetuses were monitored for 7 days. Blood samples were taken routinely for plasma nitrite measurement. Fetal brains were taken for histological assessment at the end of the experiment. Between 3 and 7 h postinjection, OK-432 administration was associated with transient suppression of fetal body and breathing movements and electtroencephalogram activity (P < 0.05), increased carotid and femoral vascular resistance (P < 0.05), but no change in blood pressure. Brain activity and behavior then returned to normal except in one fetus that developed seizures. OK-432 fetuses showed progressive, sustained vasodilatation (P < 0.05), with lower blood pressure after 4 days (P < 0.05), but normal heart rate. There were no changes in plasma nitrite levels. Histological studies showed bilateral infarction in the dorsal limb of the hippocampus of the fetus that developed seizures, but no injury in other fetuses. We conclude that a single low-dose injection of OK-432 can be associated with risk of focal cerebral injury in the preterm fetus and chronic central and peripheral vasodilatation that does not appear to be mediated by nitric oxide.

Though the lymphangioma is a benign neoplasm, it may make an invasion to vital structures by progressively growing. For lymphangioma, which progressed in such a way, surgical treatment has high morbidity and recurrence risk. On these cases, OK-432 is a frequently used sclerotherapy agent. The authors report the result they obtained by the use of single-dose OK-432 on an inoperable pediatric cervical macrocystic lymphangioma case and also their experiences.

[Effect of intravenous treatment with OK-432 on the bone marrow in patients with lung cancer].

We studied effects of OK-432 on the bone marrow and peripheral blood cells of lung cancer patients. The nuclear cell count of bone marrow increased in 5 to 7 patients upon intravenous treatment with OK-432 compared with 3 of 6 patients who were intramuscularly treated with OK-432. Serial neutrophil counts of bone marrow increased in all 7 patients treated intravenously compared with 3 of 6 patients treated intramuscularly. The mean nuclear cell count or the serial neutrophil count of bone marrow in intravenously treated patients was significantly higher than the pretreatment values (p less than 0.001). In the peripheral blood picture, the difference in white blood cells or neutrophils before and after intravenous treatment was also statistically significant (p less than 0.01). There was no change in the erythrocytic series count of bone marrow and the hemoglobin count. Our results support the superiority of intravenous OK-432 treatment over intramuscular treatment in the growth-accelerating effect on bone marrow cells, especially regarding the neutrophil series.

The bacterial immunopotentiator OK-432 induced natural killer cell activating factor (NKAF) from mouse spleen cells. OK-432-induced NKAF showed a single peak with an apparent mol. wt of 70 Kd by Sephadex G-100 chromatography and OK-432-induced interleukin 2 (IL-2) had the same mol. wt as NKAF. However, OK-432-induced interferon (IFN) showed molecular heterogeneity with two peaks at 90 Kd and 45 Kd. Further purification was achieved by Blue Sepharose affinity chromatography which copurified NKAF and IFN. The affinity-purified NKAF, however, was stable to heat (56 degrees C) and acid (pH 2) treatments. Moreover, anti-IFN failed to abolish NKAF activity and this activity was not absorbed by IL-2 dependent T cells. From isoelectric focusing analysis, a dissociation of NKAF and IFN was observed over the range of pI 6.5 to 8.0. Based on these results, KNAF appears to be a new kind of cytokine distinguishable from IFN and IL-2. PMID:6204667

Autoimmune kidney disease in MRL/Mp-lpr/lpr mice inhibited by OK-432, a streptococcal preparation.

Autoimmune MRL/Mp-lpr/lpr (MRL/l) mice were treated with the immunostimulating anti-cancer drug OK-432 (a streptococcal preparation), a potent inducer of tumour necrosis factor. Treatment was initiated at 8 weeks of age, before the onset of the autoimmune disease. OK-432 prevented the development of immune complex-mediated glomerulonephritis in a dose-dependent manner, and prolonged the life in this strain of mice. At 36 weeks of age, the incidence of proteinuria was 90% in the controls, 60% in the 0.5-KE(1 KE = 0.1 mg) treatment group, and 33% in the 2.0-KE group. The 50% survival time was 23 weeks for the controls; 32 weeks for the 0.5-KE group; and greater than 36 weeks for the 2.0-KE group. Immune complex deposition in glomeruli was significantly reduced in the treated groups. The IgM class of serum autoantibody levels was significantly increased by OK-432 treatment but the IgG class was almost unchanged. Furthermore, lymphadenopathy and splenomegaly were not suppressed. The results indicate that OK-432 may be useful in the treatment of autoimmune disease in humans. PMID:2805413

The choice of an optimal sclerosant for pleurodesis for malignant pleural effusion remains controversial. This retrospective clinical study compared the efficacy and safety of two sclerosants; talc slurry (talc-s) and OK-432. We compared the characteristics, 30/90-day success rates, and adverse events in patients with lung adenocarcinoma who underwent pleurodesis by using either OK-432 or talc-s. Propensity score matching was used to compare the two scelrosants. Ninety-four patients (mean age=71.6±9.6 years) were included in this retrospective study, of whom 64 received OK-432 and 30 received talc-s. Seventy-three patients (77.6%) were initially diagnosed with clinical stage IV lung cancer, with a 28.7% epidermal growth factor receptor mutation frequency. The propensity score-matched cohort included 26 patients from each group. The 30-day success rates for OK-432 and talc-s were 80.7% and 76.9%, respectively (odds ratio: 1.26, 95% confidence interval: 0.33-4.77, p=0.73). Neither the overall incidence of adverse events nor the 90-day success rates differed significantly. Multivariate logistic regression revealed that the predictors of 30-day success were lower drainage volume on the previous day, particularly <250mL/day, the presence of full lung expansion, and pre-therapy with an epidermal growth factor receptor-tyrosine kinase inhibitor. The median post-pleurodesis survival time was 6.9 months, which was not significantly different between the study groups. Propensity score-matched analyses showed that pleurodesis using OK-432 and talc-s demonstrated comparable efficacy and safety profiles in patients with lung adenocarcinoma. This indicated that OK-432 could be a viable alternative to talc-s in this procedure. Copyright © 2016. Published by Elsevier B.V.

Surgical excision is useful only for localized and limited lesions. The purpose of this study was to evaluate the clinical curative effect of percutaneous sclerotherapy of massive venous malformations of the face and neck using fibrin glue combined with OK-432 and pingyangmycin. Eighteen patients with massive venous malformations were treated with an injection of fibrin glue combined with OK-432 and pingyangmycin. All the patients had extreme swelling postoperatively with no major complications. The follow-up period ranged from 6 to 12 months. Twelve lesions were completely involuted, 4 lesions were mostly involuted, and 2 lesions were partially involuted. All of the patients had normal liver and kidney functions. None of the patients presented with hematologic toxic effects or signs of pulmonary involvement. Percutaneous sclerotherapy using fibrin glue combined with OK-432 and pingyangmycin provided a simple, safe, and reliable alternative treatment for massive venous malformations.

Sclerotherapy with OK-432 is recommended as a first-line treatment for lymphatic malformations. However, 40% of patients show poor response, defined by involution to <50% of the original size. It has been suggested that the OK-432 effect is highly dependent on the Toll-like receptor (TLR) 4-dependent expression of TLR7 in antigen-presenting cells. We hypothesized that the ability for TLR expression in monocytes after treatment with the TLR4-ligand lipopolysaccharide (LPS) can be used to predict successful OK-432 treatment. Blood was taken from children with low responder (LR, n = 6) and high responder (HR, n = 5) of previous OK-432 treatment. Monocytes were stimulated with LPS for 20 h. TLR expression was analyzed with fluorescence-activated cell sorting (mean fluorescence intensity). The level of significance was P ≤ 0.05. The mean age of patients in the HR group was 1.4 ± 0.9 y and in the LR group 2.8 ± 2.9 y (P = 0.31). The mean TLR4 upregulation after LPS stimulation in the HR group was significantly higher than in the LR group (factor 3.6 versus factor 1 compared with nonstimulated controls; P = 0.037). The mean TLR7 expression did not show significant differences between the groups. Dynamic TLR4 expression represents most probably a predictive parameter for the treatment of lymphatic malformations with OK-432 and should be further investigated. Copyright © 2014 Elsevier Inc.

We have recently reported that systemic and chronic administration of recombinant tumour necrosis factor alpha (TNF-alpha), as well as streptococcal preparation (OK-432), inhibits development of insulin-dependent diabetes mellitus (IDDM) in NOD mice and BB rats, models of IDDM. In this study we examined whether serum containing endogenous TNF induced by OK-432 injection could inhibit IDDM in NOD mice. Treatment twice a week from 4 weeks of age with OK-432-injected mouse serum, which contained endogenous TNF (75U), but not IL-1, IL-2 and interferon-gamma (IFN-gamma) activity, reduced the intensity of insulitis and significantly inhibited the cumulative incidence of diabetes by 28 weeks of age in NOD mice, as compared with the incidence in non-treated mice (P less than 0.01) and in mice treated with control serum (P less than 0.02). This inhibitory effect of the serum was diminished, although not significantly, by neutralization of serum TNF activity with anti-mouse TNF antibody. In the mice treated with the serum from OK-432-injected mice, Thy-1.2+ or CD8+ spleen cells decreased (P less than 0.01) and surface-Ig+ (S-Ig+) cells increased (P less than 0.05), whereas the proliferative response of spleen cells to concanavalin A (P less than 0.01) and lipopolysaccharide (P less than 0.05) increased. The results indicate that the inhibition by OK-432 treatment of IDDM in NOD mice was partially mediated by serum factors including endogenous TNF. PMID:1747949

Twenty patients with testicular hydrocele were treated with a new sclerosing therapy consisting of intrascrotal injection of OK-432 (group A Streptococcus pyogenes of human origin). The median observation period after treatment was 6 months (range 2-13 months). Eighteen patients required only one treatment. Two patients had recurrences and received repeat injection. There have been no serious side effects except for fever of 2-3 days' duration and local inflammatory reaction. Sclerotherapy with OK-432 is an efficient and easy method which can be recommended as a primary treatment for hydrocele.

Head and neck masses can present in different pathologies that usually vary according to the age of the patient. We report five cases of benign head or neck masses occurring among patients of different ages who were managed at the Bahrain Defence Force Royal Medical Services Hospital, Ar-Rifaa, Bahrain, between 2005–2014. All of the patients were treated using the sclerotherapeutic agent OK-432. Although surgical removal is usually considered optimal treatment in the management of such cases, OK-432 appears to be a promising alternative. PMID:29666687

The extended latissimus dorsi (LD) flap has become a preferred method of breast reconstruction. However, donor site seroma is the most common complication of LD flap reconstruction. The purpose of this study was to investigate the effectiveness of OK-432 on postoperative drainage and seroma formation in the site of the LD myocutaneous flap donor site. A retrospective study was conducted on 49 patients who underwent immediate breast reconstruction with extended LD flaps between July 2008 and September 2013. The patients received either OK-432 (OK-432 group, n = 24) or not (control group, n = 25) in the extended LD donor site. Outcome measures were obtained from the incidence and volume of postoperative seroma, total volume of back drains, the total drainage, indwelling period of drainage, and frequency of aspiration. There were no statistically significant differences between the two groups in terms of age, body mass index, and flap size. The incidence of seroma was 41.7% in the OK-432 group and 72% in the control group (P = 0.032). There were also significant reductions in volume of postoperative seroma (P = 0.021), total drainage volume (P < 0.001), total volume of back drains (P < 0.001), indwelling period of drainage (P = 0.004), and frequency of aspiration (P = 0.008). The use of OK-432 is a feasible option for the reduction or prevention of seroma formation at the donor site in patients undergoing immediate breast reconstruction using a LD myocutaneous flap for breast cancer.

Intralesional injection therapy with OK-432 was developed as a therapy for operatively difficult lymphangioma (cystic hygroma) and is currently becoming a first-choice treatment for this disease. The aim of this article was to evaluate the outcome and complications of the treatment of patients with auricular hematoma by OK-432 therapy. Case series with planned data collection. Yamagata University School of Medicine. We tried this therapy in 21 patients with auricular hematoma between January 2001 and February 2009. We injected OK-432 solution into the lesion with a 27-gauge needle to prevent the leak of the agent out of the hematoma. We performed this treatment on an outpatient basis without hospitalization. Disappearance or marked reduction of the lesion were observed in all patients who had this therapy, and local scarring and deformity of the auricle did not occur in any patients. As for side effects, local pain at the injection site and fever (37 degrees C-38 degrees C) were observed in a few of the patients who had this therapy, but such problems resolved within a few days. These results may allow us to speculate that intralesional injection therapy with OK-432 is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of auricular hematoma.

Radiofrequency ablation therapy (RFA) is a radical treatment for liver cancers and induces tumor antigen-specific immune responses. In the present study, we examined the antitumor effects of focal OK-432-stimulated dendritic cell (DC) transfer combined with RFA and analyzed the functional mechanisms involved using a murine model. C57BL/6 mice were injected subcutaneously with colon cancer cells (MC38) in their bilateral flanks. After the establishment of tumors, the subcutaneous tumor on one flank was treated using RFA, and then OK-432-stimulated DCs were injected locally. The antitumor effect of the treatment was evaluated by measuring the size of the tumor on the opposite flank, and the immunological responses were assessed using tumor-infiltrating lymphocytes, splenocytes and draining lymph nodes. Tumor growth was strongly inhibited in mice that exhibited efficient DC migration after RFA and OK-432-stimulated DC transfer, as compared to mice treated with RFA alone or treatment involving immature DC transfer. We also demonstrated that the antitumor effect of this treatment depended on both CD8-positive and CD4-positive cells. On the basis of our findings, we believe that combination therapy for metastatic liver cancer consisting of OK-432-stimulated DCs in combination with RFA can proceed to clinical trials, and it is anticipated to be markedly superior to RFA single therapy.

Life-Threatening Hemolytic Anemia after Intrapleural Instillation of OK-432 for Treatment of Congenital Chylothorax.

Recent reports have advocated treatment of congenital chylothorax with chemical pleurodesis via intrapleural administration of OK-432. Severe complications have not been reported, but recently we have encountered a life-threatening case of massive hemolysis after the procedure. The hemoglobin of the infant decreased from 8.7 to 3.1 g/dl within 48 h, with concomitant severe hyperbilirubinemia (472 μmol/l) requiring exchange transfusion. Frontline neonatologists should be aware of this rare but potentially life-threatening adverse reaction. In addition, it is possible that a longer indwelling time (3.5 vs. 0.5 h) for OK-432 pleurodesis may alter the therapeutic response. © 2016 S. Karger AG, Basel.

OK-432 is known to be a potent sclerosant of cystic lesions. The purpose of this study was to evaluate both its safety and pathologic effects after the infusion of OK-432 into the peritoneal cavity of rats. Twenty male rats were used in this study. Twelve rats were infused intraperitoneally with 0.2 Klinishe Einheit of OK-432 melted in 2 mL of normal saline (group 1: the treated group); four rats each were infused intraperitoneally with 0.5 mL of 99% ethanol (group 2) and normal saline (group 3), and served as the control groups. An abdominal ultrasonographic examination was performed both before and after the infusions in all rats. Three rats in group 1 and one rat in each of groups 2 and 3 were sacrificed each week following the infusion. Gross and microscopic evaluations of the peritoneum and abdominal cavity were performed on each rat. In group 1, the abdomen was clear on gross inspection and the peritoneum was unremarkable on microscopic examination. In group 2, mild-to-moderate peritoneal adhesions were revealed grossly, and inflammation and fibrosis of the peritoneum were demonstrated microscopically. In group 3, no specific abnormalities were noted on gross or microscopic examinations. Leakage or abnormal infusion of OK-432 solution into the peritoneal cavity during sclerotherapy of intra-abdominal or retroperitoneal cystic lesions does not result in any significant complications.

Gorham's disease (GD) is a rare and intractable disease characterized by marked progression of osteolysis associated with lymphangioma and/or hemangioma. Here, we describe a case of GD of the proximal tibia occurring in a 10-year-old boy. Although we could not correctly diagnose it at first, we finally diagnosed him as having GD. Progression of osteolysis of the tibia stopped 3 months after the local administration of OK-432. Thereafter, the huge bone defect with varus and extension deformity was reconstructed successfully by distraction osteogenesis using the Ilizarov method. The present case suggests that local administration of OK-432, followed by distraction osteogenesis is a treatment option for GD.

Abstract Postoperative chylothorax is a rare but well-known complication of general thoracic surgery. Medical treatment of chylothorax was reported in the past, but there is still considerable controversy on the appropriate management strategies. Two patients with esophageal cancer underwent esophagectomy, 2-field lymph node dissection, and resection of thoracic duct together with ileocolic reconstruction via the retrosternal route at our hospital. Chylothorax developed on the 32nd postoperative day (POD) in 1 patient and the 12th POD in the other, manifesting as a change in the character of thoracic drainage to turbid white. Both were immediately started on octreotide (300 μg/ day) and etilefrine (120 mg/day). When the amount of pleural effusion decreased to <50 mL/day, we performed pleurodesis with Picibanil (OK432). Thereafter, the patients gradually made satisfactory progress and resumed oral food intake, and the thoracotomy tubes were eventually removed. They have remained recurrence-free at the time of writing. In this report, we demonstrated the clinical efficacy of etilefrine for the management of postesophagectomy chylothorax. New medical treatment options for this condition are now broad and the usefulness of combined therapy consisting of a sclerosing agent, etilefrine, and octreotide is underscored, regardless of the status of the thoracic duct.

Postoperative chylothorax is a rare but well-known complication of general thoracic surgery. Medical treatment of chylothorax was reported in the past, but there is still considerable controversy on the appropriate management strategies.Two patients with esophageal cancer underwent esophagectomy, 2-field lymph node dissection, and resection of thoracic duct together with ileocolic reconstruction via the retrosternal route at our hospital. Chylothorax developed on the 32nd postoperative day (POD) in 1 patient and the 12th POD in the other, manifesting as a change in the character of thoracic drainage to turbid white. Both were immediately started on octreotide (300 μg/ day) and etilefrine (120 mg/day). When the amount of pleural effusion decreased to <50 mL/day, we performed pleurodesis with Picibanil (OK432). Thereafter, the patients gradually made satisfactory progress and resumed oral food intake, and the thoracotomy tubes were eventually removed. They have remained recurrence-free at the time of writing.In this report, we demonstrated the clinical efficacy of etilefrine for the management of postesophagectomy chylothorax. New medical treatment options for this condition are now broad and the usefulness of combined therapy consisting of a sclerosing agent, etilefrine, and octreotide is underscored, regardless of the status of the thoracic duct.

Our results confirmed that OK-432 therapy is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of ranula extending to the parapharyngeal space. The aim of this study was to evaluate the outcome and complications of the OK-432 treatment of patients with ranula extending to the parapharyngeal space. This was a case series with planned data collection at Yamagata University and Fukase clinic. We tried this therapy in six patients with ranula extending to the parapharyngeal space, between January 2001 and February 2012. We injected OK-432 solution into the lesion with an 18 or 27 gauge needle depending on the patient's condition (location and size of ranula and complications). This treatment was performed on an outpatient basis without hospitalization. Disappearance or marked reduction of the lesion were observed in all patients who had this therapy, and local scarring and deformity of the injection sites did not occur in any patients. As side effects, local pain at the injection site and fever (37-39°C) were observed in 40% of the patients who had this therapy, but such problems resolved within a few days.

We conducted a clinical trial of a cancer vaccine using NY-ESO-1 protein with polyinosinic-polycytidylic acid-poly-L-lysine carboxymethylcellulose (poly-ICLC) and/or OK-432 against solid tumors. A total of 15 patients were sequentially enrolled in 4 cohorts. Patients in cohort 1 received NY-ESO-1 protein; cohort 2a received NY-ESO-1 protein+OK-432; cohort 2b received NY-ESO-1 protein+poly-ICLC; cohort 3 received NY-ESO-1 protein+OK-432+poly-ICLC with Montanide ISA-51. The endpoints of this trial were safety, NY-ESO-1 immune responses, and clinical response. Vaccine-related adverse events observed were fever and injection-site reaction (grade 1). Two patients showed stable disease after vaccination. NY-ESO-1 antibodies were observed in 4 patients at the baseline (sero-positive) and augmented in all patients after vaccination. Eleven patients showed a conversion of negative antibody responses at baseline to positive after vaccination (seroconversion). The seroconversions were observed in all 11 sero-negative patients by the fourth immunization; in particular, it was observed by the second immunization in patients with poly-ICLC, and these induced antibody responses were stronger than those in patients immunized without poly-ICLC. The number of NY-ESO-1-specific interferon (IFN)γ-producing T cells was increased in patients immunized with poly-ICLC and/or OK-432, and furthermore, the increase of IFNγ-producing CD8 T cells in patients immunized with poly-ICLC was significantly higher than that in patients without poly-ICLC. Nonspecific activations of T-cell or antigen presenting cells were not observed. Our present study showed that poly-ICLC is a promising adjuvant for cancer vaccines.

Despite curative locoregional treatments for hepatocellular carcinoma (HCC), tumour recurrence rates remain high. The current study was designed to assess the safety and bioactivity of infusion of dendritic cells (DCs) stimulated with OK432, a streptococcus-derived anti-cancer immunotherapeutic agent, into tumour tissues following transcatheter hepatic arterial embolization (TAE) treatment in patients with HCC. DCs were derived from peripheral blood monocytes of patients with hepatitis C virus-related cirrhosis and HCC in the presence of interleukin (IL)-4 and granulocyte-macrophage colony-stimulating factor and stimulated with 0·1 KE/ml OK432 for 2 days. Thirteen patients were administered with 5 × 106 of DCs through arterial catheter during the procedures of TAE treatment on day 7. The immunomodulatory effects and clinical responses were evaluated in comparison with a group of 22 historical controls treated with TAE but without DC transfer. OK432 stimulation of immature DCs promoted their maturation towards cells with activated phenotypes, high expression of a homing receptor, fairly well-preserved phagocytic capacity, greatly enhanced cytokine production and effective tumoricidal activity. Administration of OK432-stimulated DCs to patients was found to be feasible and safe. Kaplan–Meier analysis revealed prolonged recurrence-free survival of patients treated in this manner compared with the historical controls (P = 0·046, log-rank test). The bioactivity of the transferred DCs was reflected in higher serum concentrations of the cytokines IL-9, IL-15 and tumour necrosis factor-α and the chemokines CCL4 and CCL11. Collectively, this study suggests that a DC-based, active immunotherapeutic strategy in combination with locoregional treatments exerts beneficial anti-tumour effects against liver cancer.

Lymphatic malformations (LMs) are rare congenital tumors of the lymphatic system often affecting the head and neck area. Because of cosmetic and functional symptoms most patients need to be treated. Traditionally surgical treatment has been considered to be the first-line treatment for LM. However, it is challenging because of the need for complete excision. The risk of poor cosmetic result and damage to surrounding structures is high. Since Ogita presented OK-432 as a treatment for LM in 1987, it has been widely used as the primary treatment. Many papers have been published on this topic but with relatively short follow-up times. We present a material of 36 LMs treated with OK-432 during the period of 1999-2009 and with an average follow-up time of 6 years. Immediate post-treatment results were compared with the late follow-up findings. Primary and late response to therapy was evaluated with an MRI scan by measuring the change in lesion size. At the follow-up visit, all patients were clinically examined and they answered a symptom questionnaire. Later 26/36 patients were also available for a quality of life questionnaire. Primarily 67% demonstrated a complete or marked response. At the follow-up 64% showed a complete or marked response, in 11% the final response was better than the initially observed and only 2 patients had relapsed. The initial response predicted the long-term outcome accurately and the effect of OK-432 sclerotherapy seems to be long lasting. According to the MRI evaluation 80% and subjectively 94% of the patients benefitted from the treatment. Quality of life questionnaire showed high post-treatment satisfaction. We found OK-432 sclerotherapy to be a safe and effective treatment with a long lasting effect in the management of macrocystic LMs.

Surgical treatment of extensive cervicofacial lymphatic malformations is often challenging due to a high rate of postoperative fluid re-accumulation and lesion recurrence resulting from incomplete resection. This study suggests a combined treatment of surgical resection and postoperative adjuvant OK-432 sclerotherapy via closed suction drainage. Using comparative analysis, this study aims to evaluate the efficacy of adjuvant sclerotherapy. A retrospective chart review was performed on patients who underwent surgical resection of cervicofacial lymphatic malformations between January 2009 and July 2013. Patients were divided into two groups based on whether or not adjuvant OK-432 sclerotherapy was administered via closed suction drainage after surgery. Both surgery-related and adjuvant sclerotherapy-related complications were assessed, and treatment effectiveness was measured based on the change in Cologne Disease Score (CDS) or the need for further treatment. A total of 17 patients underwent surgical resection. Nine of these patients underwent surgical resection only, while the other eight underwent surgical resection with adjuvant OK-432 sclerotherapy. The increase in total Cologne Disease Score (CDS) and change of progression parameters were significantly higher for the adjuvant sclerotherapy group compared to the surgery-only group. Additionally, there were no cases of postoperative lymphatic fluid retention among the adjuvant sclerotherapy group. The two groups exhibited similar complication rates with no statistically significant difference. Adjuvant OK-432 sclerotherapy via closed suction drainage is a safe and effective treatment modality. The combination of surgical resection and post-operative adjuvant sclerotherapy via closed suction drainage should be integrated into the treatment algorithm of extensive cervicofacial lymphatic malformation.

Orbital lymphangiomas are mostly congenital, apparent vascular space-occupying lesions, which can lead to disfiguring swelling of the periorbital soft tissues, ocular motility disorders, optic nerve compression and keratopathy. The treatment is challenging because the disease is principally incurable. Lymphangiomatous tissue can be surgically partially reduced or treated by intralesional injection of various sclerosants. In this review we report the successful use of OK-432 for destruction of a macrocystic orbital lymphangioma.

Sclerotherapy is the primary treatment for lymphatic malformations. The aim of this study was to evaluate the long-term outcome in patients with lymphatic malformations treated with the immunostimulant OK-432 as a sclerosant. Between 1998 and 2013, we enrolled 131 of 138 eligible patients treated with OK-432 for lymphatic malformations in a retrospective study. The malformations were categorised according to the International Society for the Study of Vascular Anomalies. The outcome was assessed with a clinical examination and a questionnaire. The lymphatic malformations were localised to the head/neck (60%), the trunk (20%) and the extremities (6%) or involved with more than one region (14%). Patients with microcystic (10%), macrocystic (21%) and mixed lymphatic malformations (69%) underwent a median number of three, two and two injection treatments, respectively. The median age at the first injection was 3.4 years. Good or excellent clinical outcomes were seen in 70% of the patients. The number of injections, previous treatment and lesion localisation, but not time to follow-up and cyst size, predicted the clinical outcome. OK-432 treatment resulted in a successful outcome in 70% of patients with lymphatic malformations. The long-term outcome was comparable to the short-term outcome. ©2015 Foundation Acta Paediatrica.

Wilms' tumor 1 (WT1) peptide-based vaccination has been reported for its potential usefulness in targeting several cancers. The adjuvant drug OK-432 is known to have potent immunomodulation and therapeutic properties when applied in cancer treatment and may, thus, be important to trigger the appropriate immunological response in paediatric patients with a solid tumor that are vaccinated with a WT1 peptide. Paediatric patients with a solid tumor were vaccinated with a WT1 peptide and OK-432 once every 2 weeks, for a total of seven times. Of the 24 patients, 18 completed the scheduled vaccinations. Sixteen patients had local skin symptoms and/or fever. In 1 patient, anaphylactic symptoms emerged at the time of the final injection, but these quickly subsided after the treatment. WT1-specific immunological responses were observed in 4 patients (22.2%). WT1 and HLA class I expression were confirmed in 100% and 85% of primary tumors, respectively. WT1 peptide vaccine therapy combined with OK-432 appears to be relatively safe for children. However further studies in a larger number of patients are necessary to confirm its safety and efficacy.

Retroperitoneal lymphangioma is extremely rare. Although these neoplasms are benign, they can grow progressively with subsequent compression and infiltration of the adjacent structures. Surgical excision is demanding when the lesion surrounds vital structures and it is generally fraught with a high recurrence and morbidity rate. We report the case of a huge retroperitoneal lymphangioma in a newborn treated successfully with intracystic injection of OK-432. Copyright © 2013. Published by Elsevier B.V.

We evaluated the curative effect of fibrin glue combined with OK-432 (streptococcal pyrogenic exotoxin A, Picibanil™) and bleomycin on 9 patients with sialoceles after parotidectomy. The primary lesions included pleomorphic adenomas in 6 cases and Warthin's tumours in 3 cases. After a sialocele had been diagnosed each patient had repeated aspirations and pressure dressings for 3-4 weeks, but these treatments failed. The patients were then treated with percutaneous sclerotherapy with the injection of fibrin glue 8-10 ml combined with OK-432 5 mg and bleomycin 15 mg. All the sialoceles disappeared completely after a single procedure in 2-3 weeks. The patients have been followed up for more than 6 months with no evidence of recurrent sialocele or injury to the facial nerve related to sclerotherapy. This simple, safe technique can be successfully used to treat sialoceles after parotidectomy. Copyright © 2013 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Purpose The aim of this study was to demonstrate OK-432 sclerotherapy efficacy for treatment of simple renal cysts. Materials and Methods Twenty patients with 25 symptomatic or large simple cysts were treated by ultrasonography (US)-guided percutaneous aspiration and injection of OK-432 (8 men and 12 women, mean age 63.6 years, SD 9.5). Six patients presented with flank pain, 14 presented with renal mass; renal cyst location was right, left, or bilateral sided in 9, 8, and 8 kidneys, respectively. Patients were evaluated by clinical assessment, US, or CT scan 3 months following the procedure. Complete and partial success was defined as symptom resolution with either total cyst ablation or greater than 70% reduction, respectively. Failure was defined as 30% of cyst size recurrence and/or persistent symptoms. Results Average reduction was 93.0%. Complete and partial resolution occurred in 11 (44.0%) and 13 (52.0%) cysts, respectively. One case was defined as failure, with a 64.2% size reduction from 10.9cm to 3.9cm (volume reduction rate 95.4%). Renal pain improved in all patients, regardless of complete or partial resolution. Minor complications occurred in 3 patients, 2 developed leukocytosis and 1 had mild fever (< 38.5℃) following aspiration and sclerotherapy. Successful treatment was achieved with conservative measures and NSAID therapy. Conclusion Percutaneous treatment of simple renal cysts with OK-432 sclerotherapy was found to be a safe, effective and minimally invasive procedure. PMID:17461526

The occurrence of seroma formation after axillary lymphadenectomy for breast cancer cannot be ignored. Various approaches have been used in an effort to reduce it, but these results are still controversial. We aimed to describe a new method of application of OK-432 (Sapylin, heat-treated Su strain of Streptococcus) to reduce seroma formation after axillary lymphadenectomy for breast cancer and to verify the safety and efficacy of it as a beneficial supplement for conventional surgery. A prospective, randomized analysis of consecutive quadrantectomy or mastectomy plus axillary lymphadenectomy using or not using OK-432 was designed. From July 2010 to November 2011, a total of 111 patients were enrolled in this prospective, randomized study and completed the follow-up. OK-432 applied to the axillary fossa plus placement of closed suction drainage was used in 54 patients (the experimental group); placement of closed suction drainage was used in 57 patients (the control group). There were no statistical significance between the two groups in terms of age, body mass index, treatment received, tumor size, number of removed lymph nodes, and lymph node status. Postoperative drainage magnitude and duration were significantly reduced in the experimental group (P = 0.008 and 0.003, respectively). One week after hospital discharge, fewer patients developed a palpable seroma in the experimental group: 10 in the experimental group versus 28 in the control group (P = 0.001). Fewer seromas needed aspiration (mean 1 [range 0-3] in the experimental group vs. mean 4 [range 1-5] in the control group; P < 0.001). There were no significant differences in terms of the incidence of complications associated with axillary lymphadenectomy (P = 0.941). OK-432 is a feasible and safe option for axillary lymphadenectomy for breast cancer. The use of it does not always prevent seroma formation, but it can reduce drainage magnitude and duration, as well as decrease the incidence of seroma after the removal of drainage. It may be increasingly conducted in day surgery clinics.

Percutaneous sclerotherapy of pediatric lymphatic malformations: experience and outcomes according to the agent used.

Gallego Herrero, C; Navarro Cutillas, V

Analyze statistically the success, number of sessions required and complete duration of treatment of agents used in pediatric percutaneous sclerotherapy of lymphatic malformations, to determine the most suitable. Retrospective study based on outcomes from percutaneous sclerotherapy performed on lymphatic malformations of 56 patients conducted by pediatric interventional radiologist for 14 years. As first approach, the procedure consists of ultrasound-guided introduction of sclerosing agent. Sessions were repeated until clinical resolution. Success, number of sessions and the duration of treatment were recorded and statistical treatment of the data was performed to obtain further conclusions. Lost patients in follow up and other minority agents used were excluded from the data. Eventually, 52 patients treated with OK432 (n=29), Ethibloc (n=5) and combination therapy (n=18) were included. The average number of sessions and duration in months of treatment was respectively 2.38 and 8.6 for OK432, 1.4 and 5.6 for Ethibloc, and 1.83 and 2.30 for dual therapy. The results were statistically significant for the difference in duration between OK432 and dual therapy. Also, 60-80% of patients reached proper results related to success, but the difference was no significant among the agents. Other demographic and anatomical variables were analyzed, not showing any difference, which supports the homogeneity of the sample. Despite of no significant difference in success and number of sessions among agents, longer duration of treatment with OK432 than dual therapy could mean greater health costs and probably greater disturb for patient and family.

Chylothorax, a relatively rare complication of thoracic surgery, mostly occurs on the right side. We present a 16-year-old male who received thoracoscopic surgery for left spontaneous pneumothorax. Chylothorax developed on the postoperative 2(nd) day and resolved after diet control on the 4(th) day. Unfortunately, chylothorax recurred 2 weeks later. Chest drainage and nil per os with total parental nutrition were given but in vain. Thereafter, chemical pleurodesis with OK-432 was performed. Chylothorax resolved on the next day.

We have recently shown that the relative TLR4 expression on monocytes of low responding pediatric patients after OK-432 treatment is significantly reduced after stimulation with lipopolysaccharide (LPS) compared with high responding children. The aim of this study was to perform further analysis to explain this observation. Monocytes from children with high (HR, n = 5) and low response (LR, n = 6) after previous OK-432 treatment were stimulated with LPS for 20 h and analyzed with fluorescence-activated cell sorting (mean fluorescence intensity, MFI; level of significance P ≤ 0.05). Mean MFI after LPS stimulation was comparable in both groups (HR 1142 ± 652 units, LR 839 ± 427 units, P = 0.85). Significant changes after LPS stimulation are explained by higher pre-stimulation values in the LR group compared with the HR group (950 ± 718 vs. 477 ± 341, P = 0.25) with considerable differences of the mean expression changes after LPS stimulation (HR 665 ± 683 vs. LR -111 ± 605, P = 0.08). The previously shown reduced TLR4 upregulation on monocytes after LPS stimulation in the LR group compared with the HR group can be primarily explained by TLR preconditioning. This observation implies the use of absolute values with definite thresholds.

Talc pleurodesis is commonly performed to manage refractory pleural effusion or pneumothorax. It is considered as a safe procedure as long as a limited amount of large particle size talc is used. However, acute respiratory distress syndrome (ARDS) is a rare but serious complication after talc pleurodesis. We sought to determine the risk factors for the development of ARDS after pleurodesis using a limited amount of large particle size talc. We retrospectively reviewed patients who underwent pleurodesis with talc or OK-432 at the University of Tokyo Hospital. Twenty-seven and 35 patients underwent chemical pleurodesis using large particle size talc (4 g or less) or OK-432, respectively. Four of 27 (15%) patients developed ARDS after talc pleurodesis. Patients who developed ARDS were significantly older than those who did not (median 80 vs 66 years, P = 0.02) and had a higher prevalence of underlying interstitial abnormalities on chest computed tomography (CT; 2/4 vs 1/23, P < 0.05). No patient developed ARDS after pleurodesis with OK-432. This is the first case series of ARDS after pleurodesis using a limited amount of large particle size talc. Older age and underlying interstitial abnormalities on chest CT seem to be risk factors for developing ARDS after talc pleurodesis. © 2017 Asian Pacific Society of Respirology.

To investigate the efficacy and toxicity of immunomodulatory therapy (IMT) alone or as an add-on to palliative/salvage chemotherapy in patients with refractory/recurrent epithelial ovarian cancer (EOC). We retrospectively analyzed the efficacy and toxicity of IMT in 15 patients with refractory/recurrent EOC who had previously received multiple chemotherapy regimens. The median age of the patients was 56 years (range, 41-75 years). Three patients were platinum-sensitive, two were platinum-resistant, and the remaining 10 patients were refractory to platinum-based front-line chemotherapy. IMT consisted of picibanil (OK-432) on Day 1, interleukin-2 and/or interferon-α on Day 2 administered by subcutaneous injection (every week or 2-weekly). Five patients never received metronomic oral cyclophosphamide. After IMT, three patients achieved partial remission (PR, lasting for 11 months, ≥ 12 months, and 16 months), and six patients had stable disease (SD). The disease stabilizing rate (PR+SD) was 60% (3/3 in platinum-sensitive and 6/12 in platinum-resistant/refractory patients). The absolute lymphocyte count (ALC) at 1 month after IMT was significantly higher in the PR+SD group (median 1242.0/μL) than in the progression group (median 325.0/μL) (p = 0.012). No ≥ Grade 3 toxicities were observed. The median post-IMT survival time was 12 months (range, 2-39 months). IMT alone or add-on to palliative/salvage chemotherapy for refractory/recurrent EOC achieves a substantial disease stabilizing rate without severe toxicity, which might be a potential option in selected patients. The ALC 1 month after IMT could be an early indicator to disease stabilization. Copyright © 2015. Published by Elsevier B.V.

1992-01-01

Results of 6589 gastric cancer operations at the Department of Surgery, Seoul National University Hospital, from 1970 to 1990 were reported. About two thirds (76.6%) were advanced gastric cancer (stages III and IV). The 5-year survival rate of operated stage III gastric cancer was only 30.6%, with frequent recurrence. Conversely, cell-mediated immunities of advanced gastric cancer patients were significantly decreased. Therefore, to improve the cure rate and to prevent or delay recurrence, curative surgery with confirmation of free resection margins and systematic lymph node dissection of perigastric vessels were performed and followed by early postoperative immunotherapy and chemotherapy (immunochemosurgery) in stage III patients. To evaluate the effect of immunochemosurgery, two randomized trials were studied in 1976 and 1981. In first trial, 5-fluorouracil, mitomycin C, and cytosine arabinoside for chemotherapy and OK 432 for immunotherapy were used. The 5-year survival rates for surgery alone (n = 64) and immunochemosurgery (n = 73) were 23.4% and 44.6%, respectively, a significant difference. In the second trial, there were three groups: group I, immunochemosurgery (n = 159); group II, surgery and chemotherapy (n = 77); and group III, surgery alone (n = 94). 5-Fluorouracil and mitomycin C for chemotherapy and OK-432 for immunotherapy were administered for 2 years. The 5-year survival rate of group I was 45.3%, significantly higher than the 29.8% of group II and than the 24.4% of group III. The postoperative 1-chloro-2.4-dinitrobenzene test, T-lymphocyte percentage, phytohemagglutinin- and con-A-stimulated lymphoblastogenesis and the antibody-dependent cell-mediated cytotoxicity test showed more favorable values in the immunochemosurgery group. Therefore, immunochemosurgery is the best multimodality treatment for advanced gastric cancer. PMID:1417176

This study retrospectively reviews the results of sclerotherapy using several sclerosants for congenital lesions of the head and neck. Between May 1990 and May 2002, patients with lymphatic malformations were treated by sclerotherapy; 10 with bleomycin, and 25 with OK-432. OK-432 sclerotherapy was also applied in 9 patients with plunging ranula and in 1 patient with branchial anomaly. Percutaneous sclerotherapy with ethanolamine oleate was used in 29 patients with venous malformations, and 28 patients with pyriform sinus fistula were treated by trichloroacetic acid chemocauterization. Overall, two thirds of patients with these lesions showed marked to complete response. One case of mortality occurred in the bleomycin sclerotherapy group. However, no major complications by other sclerosants were found. In lymphatic malformations, history of excision before sclerotherapy was a poor prognostic factor. Sclerotherapy using these sclerosants is a safe and effective primary treatment for congenital lesions in the head and neck.

To evaluate survival and distant tumor growth after radiofrequency ablation (RFA) and local OK-432 injection at a single tumor site in a rabbit model with intra- and extrahepatic VX2 tumors and to examine the effect of this combination therapy, which we termed immuno-radiofrequency ablation (immunoRFA), on systemic antitumor immunity in a rechallenge test. Our institutional animal care committee approved all experiments. VX2 tumors were implanted to three sites: two in the liver and one in the left ear. Rabbits were randomized into four groups of seven to receive control, RFA alone, OK-432 alone, and immunoRFA treatments at a single liver tumor at 1 week after implantation. Untreated liver and ear tumor volumes were measured after the treatment. As the rechallenge test, tumors were reimplanted into the right ear of rabbits, which survived the 35 weeks and were followed up without additional treatment. Statistical significance was examined by log-rank test for survival and Student's t test for tumor volume. Survival was significantly prolonged in the immunoRFA group compared to the other three groups (P < 0.05). Untreated liver and ear tumor sizes became significantly smaller after immunoRFA compared to controls (P < 0.05). In the rechallenge test, the reimplanted tumors regressed without further therapy compared to the ear tumors of the control group (P < 0.05). ImmunoRFA led to improved survival and suppression of distant untreated tumor growth. Decreases in size of the distant untreated tumors and reimplanted tumors suggested that systemic antitumor immunity was enhanced by immunoRFA.

Pretreatment with two biological response modifiers (BRM), OK-432 and PS-K, protected mice from lethal infection by murine cytomegalovirus (MCMV). This was evidenced by an increase in 50% lethal doses and a decrease in titers of infectious viruses replicated in the liver and spleen. Spleen cells from the BRM-treated mice augmented the natural killer (NK) cell activity and suppressed the replication of MCMV in vitro. During MCMV infection, the NK cell activity of the spleen cells was maintained at a high level in the BRM-treated mice, whereas it was severely impaired in untreated mice. The BRM-induced protection was nullified by concomitant administration of antiasialo GM1 antibody. Interferon was neither induced by BRM treatment nor enhanced in BRM-pretreated and MCMV-infected mice. Thus, the protective effect of OK-432 and PS-K seems to be based on activation of NK cells and prevention of MCMV-induced inhibition of the NK cell activity. PMID:6202880

Therapeutic vaccination with dendritic cells (DCs) pulsed with tumor cell lysate vaccine (H-D) represents an attractive approach for hepatocellular carcinoma (HCC) treatment. However, the efficacy of this approach is not most satisfactory for the low levels of T helper 1 (Th1)-type cytokines secretion and weak T cell responses. In this study, in order to increase the potency of H-D, two tandem repeats of microbial HSP70 peptide epitope 407-426 (2mHSP70(407-426), M2) which has been demonstrated to be effective in enhancing DC maturation were applied. The DC vaccine (HM-D) which was HCC tumor cell lysate pulsed with M2 was developed. Nevertheless, the immunotherapeutic effect was still not satisfactory enough even some promotion was obtained. Therefore, OK-432 (OK), which is a useful anti-cancer agent and effectively in stimulating DC maturation, was introduced to HM-D. Our results demonstrated that treatment with the improved DC vaccine which was tumor cell lysate pulsed with M2 and OK (HMO-D), compared with H-D and HM-D, significantly increased cell surface markers (MHC-I and II, CD40, CD80, CD86 and CD11c) expression on DCs, enhanced Th1-type cytokines (IL-12, TNF-α and IFN-γ) production but not Th2-type cytokine (IL-5) production, induced remarkable high levels of lymphocytes proliferation and CD8(+) cytotoxic T-lymphocyte (CTL). Furthermore, immunization with HMO-D effectively reduced tumor progression and enhanced the survival of mice with H22 tumors. Besides, we also found that the capability of M2 in inducing the Th1 cytokines was stronger than OK. In view of these results, HMO-D vaccination provided a novel immunotherapeutic approach for the treatment of HCC. Copyright © 2011 Elsevier B.V. All rights reserved.

Immunogenicity of a long 20-mer NY-ESO-1f peptide vaccine was evaluated in a lung cancer patient TK-f01, immunized with the peptide with Picibanil OK-432 and Montanide ISA-51. We showed that internalization of the peptide was necessary to present CD8 T-cell epitopes on APC, contrasting with the direct presentation of the short epitope. CD8 T-cell responses restricted to all five HLA class I alleles were induced in the patient after the peptide vaccination. Clonal analysis showed that B*35:01 and B*52:01-restricted CD8 T-cell responses were the two dominant responses. The minimal epitopes recognized by A*24:02, B*35:01, B*52:01 and C*12:02-restricted CD8 T-cell clones were defined and peptide/HLA tetramers were produced. NY-ESO-1 91-101 on A*24:02, NY-ESO-1 92-102 on B*35:01, NY-ESO-1 96-104 on B*52:01 and NY-ESO-1 96-104 on C*12:02 were new epitopes first defined in this study. Identification of the A*24:02 epitope is highly relevant for studying the Japanese population because of its high expression frequency (60%). High affinity CD8 T-cells recognizing tumor cells naturally expressing the epitopes and matched HLA were induced at a significant level. The findings suggest the usefulness of a long 20-mer NY-ESO-1f peptide harboring multiple CD8 T-cell epitopes as an NY-ESO-1 vaccine. Characterization of CD8 T-cell responses in immunomonitoring using peptide/HLA tetramers revealed that multiple CD8 T-cell responses comprised the dominant response. Copyright © 2012 UICC.

The therapeutic gold standard of cystic hygroma is its complete resection. Because of its growth pattern and its main location in the head and neck region complete resection is not always possible. An alternative is the local injection of Picibanil, but only few cases have been published about its use in infants. We retrospectively analyzed the data of 8 infants (age: 2 weeks-12 months) who got Picibanil therapy because of cystic hygroma in the time period 2002 until 2006. Follow up ranged from 3 months up to 3 years. During the postoperative period all patients had local swelling, in 4 cases accompanied with local inflammation and fever. Tumor reduction of >50% was obtained in 7 of 8 patients. Local injection of Picibanil in infants with cystic hygroma seems to be a safe alternative to surgical therapy, especially when complete tumor resection means damage of important neighbouring structures. Prospective trials are necessary to confirm the better outcome after therapy with Picibanil compare to primary surgery.

Effects of some plant lectins on hydrogen peroxide release from macrophages induced with streptococcal preparation OK-432.

Concanavalin A and phytohemagglutinin were found to cause marked inhibition of H2O2 release from macrophages induced with killed streptococci (preparation OK-432). The inhibitory effect of these two lectins on the H2O2 release from macrophages was observed with spontaneous and wheat germ lectin-triggered H2O2 release. This suggests that the lectins act directly on the macrophage H2O2-releasing function, per se, but not on the wheat germ lectin-H2O2 release-enhancing process. Concanavalin A exhibited its inhibitory action on macrophage H2O2 release by specific binding to D-mannopyranoside receptor sites on the macrophage cell surface. Galactose-binding lectins, peanut agglutinin, and soybean agglutinin failed to inhibit, but, on the other hand, slightly enhanced macrophage H2O2 release. The effect of these five lectins on the phagocytosis of latex particles by macrophages was tested. Wheat germ lectin, concanavalin A, and phytohemagglutinin significantly depressed the macrophage phagocytosis, whereas peanut agglutinin and soybean agglutinin failed to show any inhibitory action.

Lymphatic disease is a rarely cause of some very unspecific genitourinary manifestations, assuming a diagnostic challenge in most cases. The aim of this paper is to warn about the possible etiology of these urological lymphatic presentations and discuss its management. Retrospective review of clinical data in pediatric patients with urological pathology of lymphatic origin between 2008-2014. Three patients, two boys and a girl, were included. The complaints were: redundant prepuce, inguinal scrotal tumor and urinary incontinence. Clinical, diagnosis and treatment protocol is described. The first case is a male with genital lymphedema presented at birth as a redundant prepuce and the subsequent emergence of lower limb lymphedema, treated with compression bandages. The second case, a groin lymphangioma which debuted as a sudden painless inguinal tumor simulating a cord cyst, it was sclerosed and treated with OK- 432. Finally, a preteen who consulted for involuntary leakage of urine, genital lymphedema likely primary cause (lymphodisplasia) or malformation was diagnosed, which improved with two Lipiodol® embolization. Genitourinary manifestations can be the debut of more complex lymphatic pathology, so it is necessary to consider this cause, uncommon and nonspecific. Its management must be conservative initially by compression bandages, OK-432 or embolization with Lipiodol®.

Surgical excision is thought to be the standard treatment of choice for lymphatic malformations. However, when the lesions are limited to the face only, surgical scar and facial nerve injury may impair cosmetics and facial expression. Sclerotherapy, an injection of a sclerosing agent directly through the skin into a lesion, is an alternative method. By evaluating facial nerve conduction, we observed the long-term effect of facial lymphatic malformations after intralesional injection of OK-432 and correlated the findings with anatomic outcomes. One 12-year-old boy with a lesion over the right-side preauricular area adjacent to the main trunk of facial nerve and the other 5-year-old boy with a lesion in the left-sided cheek involving the buccinator muscle were enrolled. The follow-up data of more than one year, including clinical appearance, computed tomography (CT) scan and facial nerve evaluation were collected. The facial nerve conduction study was normal in both cases. Blink reflex in both children revealed normal results as well. Complete resolution was noted on outward appearance and CT scan. The neurophysiologic data were compatible with good anatomic and functional outcomes. Our report suggests that the inflammatory reaction of OK-432 did not interfere with adjacent facial nerve conduction.

The current prospective randomized study was designed to compare the effects of intracavitary (i.c.) chemotherapy vs immunotherapy vs immunochemotherapy for malignant effusion. Between 1992 and 1995, a total of 42 patients with malignant effusion were registered, and 41 patients were eligible for statistical analysis. The primary diseases of the eligible patients included 27 gastric, four colorectal, four pancreatic, three lung, two liver and one oesophageal cancers. The patients with malignant effusion were randomly assigned into one of three i.c. therapeutic regimens: chemotherapy alone with weekly injection of anticancer agents (ACAs: cisplatin, mitomycin-C, adriamycin, etc.) (Group A, n = 13); immunotherapy alone with weekly injection of streptococcal preparation OK-432 (Group B, n = 14); or immunochemotherapy with ACAs and OK-432 (Group C, n = 14). The response of the effusion, patient survival and the kinetics of cytokines in the effusion were compared. There were no differences in the patients' backgrounds. The side-effects of the regimens included pain, anorexia, fever, leucopenia and anaemia and there were no differences in their incidence among the three groups. One patient died after cisplatin (CDDP) administration in Group A. Cytologic examination revealed that tumour cells in the effusion disappeared in 23% of Group A cases, 36% of Group B cases and 36% of Group C cases. The malignant effusion did not disappear in any of the Group A cases; however, the effusion disappeared in 29% of Group B cases and 43% of Group C cases (P = 0.03, Group A vs Group C). Furthermore, the 50% survival period was 1.6 months for Group A, 2.4 months for Group B and 3.5 months for Group C. The 6-month survival rate was 7% for Group A, 6% for Group B and 34% for Group C, and the 1-year survival rate was 0%, 0% and 17% respectively (P = 0.048, Group A vs Group C by the log-rank test). The analysis of the cytokine kinetics revealed a prominent increase in the level of interleukin-6 in the effusion in Group C. These results suggest that i.c. immunochemotherapy with OK-432 and ACAs may be more beneficial than i.c. chemotherapy alone or immunotherapy alone. © 1999 Cancer Research Campaign PMID:10360655

To determine the feasibility, safety and histological change of preoperative endoscopic ultrasound-guided fine-needle injection (PEU-FNI) of immature DCs (iDCs) with OK-432 in pancreatic cancer patients. Nine patients enrolled in the trial (DC group) and were compared with 15 patients operated on without iDC injection (non-DC group). Adverse events of PEU-FNI and postoperative complications were evaluated according to CTC-AE ver.3.0 and the Clavien-Dindo classification/ISGPF definition, respectively. Histological changes within the tumor and lymph nodes were evaluated by immunohistochemical examination of infiltrating inflammatory cells (CD4+, CD8+, Foxp3+ and CD83+). There were no severe toxicities following PEU-FNI, except for one transient grade 3 fever, and there were no significant differences in the incidence of postoperative complications between the two groups. Colliquative necrosis and diffusely scattered TUNEL-positive cells were observed at the injection sites. CD83+ cells significantly accumulated in the regional lymph nodes of the DC group as well as Foxp3+ cells in the regional and distant lymph nodes. The two DC group patients, one of which was stage IV with distant lymph node metastasis, survived more than 5 years without requiring adjuvant theraphy. PEU-FNI was feasible and safe, and further study needs to confirm and enhance antitumor responses.

OBJECTIVE: Here, we describe our experience with different therapeutic modalities used to treat cystic lymphangiomas in children in our hospital, including single therapy with OK-432, bleomycin and surgery, and a combination of the three modalities. METHODS: We performed a retrospective, cross-sectional study including patients treated from 1998 to 2011. The effects on macrocystic lymphangiomas and adverse reactions were evaluated. Twenty-nine children with cystic lymphangiomas without any previous treatment were included. Under general anesthesia, patients given sclerosing agents underwent puncture of the lesion (guided by ultrasound when necessary) and complete aspiration of the intralesional liquid. The patients were evaluated with ultrasound and clinical examinations for a maximum follow-up time of 4 years. RESULTS: The proportions of patients considered cured after the first therapeutic approach were 44% in the surgery group, 29% in the bleomycin group and 31% in the OK-432 group. These proportions were not significantly different. Sequential treatment increased the rates of curative results to 71%, 74% and 44%, respectively, after the final treatment, which in our case was approximately 1.5 applications per patient. CONCLUSION: The results of this study indicate that most patients with cystic lymphangiomas do not show complete resolution after the initial therapy, regardless of whether the therapy is surgical or involves the use of sclerosing agents. To achieve complete resolution of the lesions, either multiple operations or a combination of surgery and sclerotherapy must be used and should be tailored to the characteristics of each patient.

Venous malformations of the face and neck involve multiple anatomical spaces and encase critical neuromuscular structures, making surgical treatment difficult; high recurrence rates and high morbidity are well documented. The purpose of this study was to evaluate the clinical curative effect of combination compartmentalisation and sclerotherapy for the treatment of massive venous malformations of the face and neck. Sixteen patients with massive venous malformations of the face and neck region (12 males and four females; mean age: 14.9 years, range: 6-22 years) were treated with compartmentalisation using silk sutures followed by injections of 0.1 mg OK-432 and 8 mg pingyangmycin into each small compartment. The injections were performed every two weeks. All lesions received three to six treatments. All the patients had significant swelling and mild pain postoperatively for a period of one to two weeks with no major complications. One patient had transient facial paresis, which resolved spontaneously within two weeks. The follow-up period ranged from three to 14 months (median: 7.1 months). The treatments resulted in the following: four of the lesions were completely involuted, six were mostly involuted, five were partially involuted, and one experienced a small involution. All of the patients had normal liver and kidney functions and normal lung fields on chest X-ray. Compartmentalisation followed by injection of OK-432 and pingyangmycin into each compartment provided a simple, safe, and reliable alternative treatment for massive venous malformations of the face and neck.

Background Dendritic cells (DCs) play a pivotal role in the immune system. There are many reports concerning DC-based immunotherapy. The differentiation and maturation of DCs is a critical part of DC-based immunotherapy. We investigated the differentiation and maturation of DCs in response to various stimuli. Methods Thirty-one patients with malignant bone and soft tissue tumors were enrolled in this study. All the patients had metastatic tumors and/or recurrent tumors. Peripheral blood mononuclear cells (PBMCs) were suspended in media containing interleukin-4 (IL-4) and granulocyte-macrophage colony stimulating factor (GM-CSF). These cells were then treated with or without 1) tumor lysate (TL), 2) TL + TNF-α, 3) OK-432. The generated DCs were mixed and injected in the inguinal or axillary region. Treatment courses were performed every week and repeated 6 times. A portion of the cells were analyzed by flow cytometry to determine the degree of differentiation and maturation of the DCs. Serum IFN-γ and serum IL-12 were measured in order to determine the immune response following the DC-based immunotherapy. Results Approximately 50% of PBMCs differentiated into DCs. Maturation of the lysate-pulsed DCs was slightly increased. Maturation of the TL/TNF-α-pulsed DCs was increased, commensurate with OK-432-pulsed DCs. Serum IFN-γ and serum IL-12 showed significant elevation at one and three months after DC-based immunotherapy. Conclusions Although TL-pulsed DCs exhibit tumor specific immunity, TL-pulsed cells showed low levels of maturation. Conversely, the TL/TNF-α-pulsed DCs showed remarkable maturation. The combination of IL-4/GM-CSF/TL/TNF-α resulted in the greatest differentiation and maturation for DC-based immunotherapy for patients with bone and soft tissue tumors. PMID:23300824

Objective Pleurodesis is an effective therapy for malignant pleural effusion (MPE). While interstitial lung disease (ILD) has been regarded as a serious complication of pleurodesis, its clinicopathological characteristics have not been fully understood. This study was conducted to elucidate the incidence of ILD and the risk factors for ILD in patients who underwent pleurodesis to control MPE. Methods The medical records of patients who underwent pleurodesis in Aichi Medical University between March 2008 and February 2013, the period before the approval of talc in Japan, were retrospectively analyzed. Results A total of 84 patients underwent pleurodesis, all using OK-432. ILD occurred in 13 patients (15.5%). The development of ILD after pleurodesis was significantly associated with old age (odds ratio [OR]: 4.82, 95% confidence interval [CI]: 1.22-19.08) and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) treatment (OR: 5.97, CI: 1.7-20.9). A multivariate analysis revealed that >67 years of age (p=0.01) and EGFR-TKI treatment (p=0.02) were significantly associated with the development of pleurodesis-related ILD. Among the patients who received both pleurodesis and EGFR-TKIs (n=23), 8 patients developed ILD. All of these patients were receiving EGFR-TKI therapy at the time of pleurodesis or within 30 days after pleurodesis. In contrast, no cases of ILD were observed among the patients who stopped EGFR-TKIs before pleurodesis or started EGFR-TKIs at more than 30 days after pleurodesis. Conclusion ILD seemed to be a frequent complication of pleurodesis in patients using OK-432, especially elderly patients and those who underwent pleurodesis while receiving EGFR-TKI therapy or who started EGFR-TKI therapy within 30 days after pleurodesis.

Hamamoto et al (1) were able to demonstrate that combination therapy of a lung tumor by using radiofrequency ablation (RFA) with local injection of an immunostimulant, OK-432, resulted in improved survival when compared with other therapies tested in a VX2 rabbit model. In addition, not only was greater tumor regression seen in a second distant ear tumor implanted prior to the therapy, but also reduced tumor growth was seen when a second tumor implantation (ie, rechallenge) was attempted. These factors strongly suggest the successful activation of systemic antitumor immunity using this approach in this specific tumor model.

A phase I+II clinical trial of vaccination with MAGE-A4 protein complexed with cholesteryl pullulan melanoma antigen gene-A4 nanogel (CHP-MAGE-A4) is currently underway in patients with MAGE-A4-expressing cancer. In the present study, the primary phase I endpoint was to test the safety of the administration of 300 µg CHP-MAGE-A4 with and without OK-432. Another aim of the study was to clarify the details of the specific humoral immune response to vaccination. The 9 patients enrolled for phase I were vaccinated 6 times, once every 2 weeks: 3 patients with 100 µg and 3 patients with 300 µg CHP-MAGE-A4, and 3 patients with 300 µg CHP-MAGE-A4 plus 0.5 clinical units of OK-432. Toxicities were assessed using Common Terminology Criteria for Adverse Events v3.0. Clinical response was evaluated by modified Response Evaluation Criteria in Solid Tumours. Immunological monitoring of anti-MAGE-A4-specific antibodies was performed by ELISA of pre- and post-vaccination patient sera. The 6 vaccinations produced no severe adverse events. Stable disease was assessed in 4/9 patients. Anti-MAGE-A4 total immunoglobulin (Ig)G titers increased in 7/9 patients. Efficacious anti-MAGE-A4 IgG1, 2 and 3 antibody responses were observed in 7/9 patients. Among them, positive conversions to T helper 2 (Th2)-type antibody responses (IgG4 and IgE) were observed after frequent vaccination in 4/7 patients. The Th2 conversion was possibly associated with undesirable clinical observations, including progressive disease and the appearance of a new relapse lesion. The present study suggested that frequent vaccinations activated a Th2-dominant status in the cancer patients. The identification of a time-dependent IgG subclass and IgE antibody production during vaccination protocols may be a useful surrogate marker indicating a potentially undesirable change of the immunological environment for an effective antitumor immune response in cancer patients.

In the early period following radical hepatectomy for hepatoma, recurrences in the remaining liver are frequently found. In regenerating liver, implantation and growth of tumour cells released into the portal system during surgical treatment might be promoted. We examined the relationship between liver regeneration and the formation of metastases following hepatic resection. Intraportal injections of rat ascites containing hepatoma AH130 cells at a concentration of 1 x 10(5) cells 0.2 ml-1 were made at various periods following two thirds liver resection in rats. Tumour cell injections immediately at 24 h after surgery resulted in an increased number of hepatic metastases compared with control animals. Tumour cell injections 2 weeks after hepatectomy, however, had no significant difference in effect compared with control rats. In contrast, tumour cells injected immediately after removal of half of the caudate lobe resulted in the same number of metastases as control animals. These results demonstrate that the number of artificially induced hepatic metastases was increased during an initial period of active liver regeneration and was proportional to the volume of hepatectomy. The effect of 5-fluorouracil (5FU) or mitomycin C (MMC) as inhibitors of hepatic regeneration on liver metastasis after hepatectomy was studied. The administration of 5FU (20 mg kg-1) or MMC (0.2 mg kg-1) immediately, 24 and 48 h after hepatectomy resulted in a marked reduction in metastatic lesions. The administration of 5FU caused delays in weight gain and decreases in the wet weight of remaining liver, while MMC had no effect on either. Accordingly, results of 5FU administration may be due to inhibitory effects on liver regeneration whilst that of MMC administration may be due to cytocidal antitumour effect. The effect of OK-432 as an immunoactivator on the implantation and growth of tumour cells in regenerating liver was also studied. Pretreatment with OK-432, 0.5 mg intraperitoneally on 7 consecutive days, had no effect on hepatic metastases. The pathophysiology of liver regeneration may enhance hematogenous hepatic metastasis and release of tumour cells during surgical manipulation may represent an important cause of recurrence following hepatic resection.

Reported herein is the case of a terminal patient with advanced gastric cancer who was shown an extremely effective response to immunochemotherapy. The patient, a 62-year-old female, was determined as having a gastric cancer, Borr. type 2, originating in the pyloric antrum. The tumor was found to be H3P3S2N2 (stage IV), and its histology revealed a mucus-producing papillary adeno-carcinoma, ss gamma, n(+), ly2, and V1. Thus the patient underwent a distal gastrectomy, and was given an operative administration of MMC, followed by postoperative immunochemotherapy with FT 207 and OK 432. Consequently, no ascites were noticed throughout the recuperative course, and repeated CT scannings of the hepatic metastatic lesions, revealed a remarkable regression. Two years after this operation, she resumed normal daily life. Further, her preoperatively elevated tumor markers have returned to normal.

This study compared the effect of orthokeratology (OK) lens wear on corneal topography and microstructure between the 1-night and 30-night wearers to predict any adverse responses of the eyes to long-term OK lens wear. Nine rhesus monkeys with one eye wearing an OK lens and the fellow eye wearing a rigid gas permeable (RGP) lens were used in this study. The lenses were worn for 11 hours, with the measurement of corneal curvature and thickness and axial components of the eye at 0 night (n = 9), 1 night (n = 9), and 30 nights (n = 6). Histology was performed at 1 and 30 nights of lens wear. Corneal surface power in the 3-mm central region was reduced in the OK eye when compared with the RGP eye (P < 0.05). Central corneal thickness was only reduced in 30 nights of OK lens wear (P < 0.05). Under light microscopy, the 1-night OK or RGP eyes showed normal morphology in all layers of the cornea. The 30-night OK eyes showed a thinned central corneal epithelium and a thickened but less stratified paracentral corneal epithelium when compared with the 30-night RGP eyes. Under electron microscopy, intercellular junctions of corneal epithelium in the 30-night OK eyes were much looser than those in the 1-night OK eyes. However, the density and morphology of hemidesmosomes were similar between the OK and RGP eyes at 30 nights of lens wear. Overnight OK can change the corneal curvature through anterior corneal remodeling, resulting in an effective correction of myopia. However, a decrease in intercellular junctions during long-term wear may compromise the functions of the corneal epithelium as a border mechanical barrier.

This study demonstrates a significant correlation between the American Knee Society (AKS) Clinical Rating System and the Oxford Knee Score (OKS) and provides a validated prediction tool to estimate score conversion. A total of 1022 patients were prospectively clinically assessed five years after TKR and completed AKS assessments and an OKS questionnaire. Multivariate regression analysis demonstrated significant correlations between OKS and the AKS knee and function scores but a stronger correlation (r = 0.68, p < 0.001) when using the sum of the AKS knee and function scores. Addition of body mass index and age (other statistically significant predictors of OKS) to the algorithm did not significantly increase the predictive value. The simple regression model was used to predict the OKS in a group of 236 patients who were clinically assessed nine to ten years after TKR using the AKS system. The predicted OKS was compared with actual OKS in the second group. Intra-class correlation demonstrated excellent reliability (r = 0.81, 95% confidence intervals 0.75 to 0.85) for the combined knee and function score when used to predict OKS. Our findings will facilitate comparison of outcome data from studies and registries using either the OKS or the AKS scores and may also be of value for those undertaking meta-analyses and systematic reviews. ©2015 The British Editorial Society of Bone & Joint Surgery.

Kang, Pauline; Swarbrick, Helen

2016-09-01

To compare peripheral refraction changes along the horizontal and vertical meridians induced by three different orthokeratology (OK) lens designs: BE, Paragon CRT, and Contex lenses. Nineteen subjects (6M, 13F, mean age 28 ± 7 years) were initially fitted with BE OK lenses in both eyes which were worn overnight for 14 days. Central and peripheral refraction and corneal topography were measured at baseline and after 14 nights of lens wear. After a minimum 2-week washout period, one randomly selected eye was re-fitted with a Paragon CRT lens and the other eye with a Contex OK lens. Measurements were repeated before and after 14 nights of lens wear. The three different OK lenses caused significant changes in peripheral refraction along both the horizontal and vertical visual fields (VFs). BE and Paragon CRT lenses induced a significant hyperopic shift within the central ±20° along the horizontal VF and at all positions along the vertical meridian except at 30° in the superior VF. There were no significant differences in peripheral refraction changes induced between BE and Paragon CRT lenses. When comparing BE and Contex OK lens designs, BE caused greater hyperopic shifts at 10° and 30° in the temporal VF and at center, 10°, and 20° in the superior VF along the vertical meridian. Furthermore, BE lenses caused greater reduction in Flat and Steep K values compared to Contex OK. OK lenses induced significant changes in peripheral refraction along the horizontal and vertical meridians. Despite the clinically significant difference in central corneal flattening induced by BE and Contex OK lenses, relative peripheral refraction changes differed minimally between the three OK lens designs. If the peripheral retina influences refractive error development, these results suggest that myopia control effects are likely to be similar between different OK lens designs.

Spatial interpolation method is the basis of soil heavy metal pollution assessment and remediation. The existing evaluation index for interpolation accuracy did not combine with actual situation. The selection of interpolation methods needs to be based on specific research purposes and research object characteristics. In this paper, As pollution in soils of Beijing was taken as an example. The prediction accuracy of ordinary kriging (OK) and inverse distance weighted (IDW) were evaluated based on the cross validation results and spatial distribution characteristics of influencing factors. The results showed that, under the condition of specific spatial correlation, the cross validation results of OK and IDW for every soil point and the prediction accuracy of spatial distribution trend are similar. But the prediction accuracy of OK for the maximum and minimum is less than IDW, while the number of high pollution areas identified by OK are less than IDW. It is difficult to identify the high pollution areas fully by OK, which shows that the smoothing effect of OK is obvious. In addition, with increasing of the spatial correlation of As concentration, the cross validation error of OK and IDW decreases, and the high pollution area identified by OK is approaching the result of IDW, which can identify the high pollution areas more comprehensively. However, because the semivariogram constructed by OK interpolation method is more subjective and requires larger number of soil samples, IDW is more suitable for spatial prediction of heavy metal pollution in soils.

Microbial keratitis in overnight orthokeratology: review of the first 50 cases.

PubMed

Watt, Kathleen; Swarbrick, Helen A

2005-09-01

Despite growing evidence for clinical efficacy of orthokeratology (OK) for the temporary reduction of myopic refractive error, there has been an increasing number of reports of microbial keratitis (MK) in association with overnight wear of OK lenses. This article analyzes the first 50 cases of MK reported in overnight OK, in order to define the spectrum of the disease and to identify possible risk factors. All reported cases of presumed MK in overnight OK from 2001 onwards were included in the analysis. Demographic data of patients affected and lenses worn, and details of the disease process and possible risk factors were extracted from these reports. Most cases of MK in OK were reported from East Asia (80%) and most affected patients were Asian (88%). The peak age range was from 9 to 15 years (61%). Although Pseudomonas aeruginosa was the predominant organism implicated in this series of cases (52%), an alarmingly high frequency of Acanthamoeba infection (30%) was found. Inappropriate lens care procedures, patient noncompliance with practitioner instructions, and persisting in lens wear despite discomfort emerged as potential risk factors. The high frequency of MK in overnight OK in young Asian patients is likely to reflect the demographics of the OK lens-wearing population. The high frequency of Acanthamoeba infection strongly suggests that tap water rinsing should be eliminated from the lens care regimen for overnight OK. This study does not reveal the absolute incidence or relative risk of MK in overnight OK, and it is therefore premature to ascribe increased risk to this lens-wearing modality compared with other contact lens modalities.

The Oxford Knee Score (OKS) is a valid, short, self-administered, and site- specific outcome measure specifically developed for patients with knee arthroplasty. This study aimed to cross-culturally adapt and validate the OKS to be used in Turkish-speaking patients with osteoarthritis of the knee. The OKS was translated and culturally adapted according to the guidelines in the literature. Ninety-one patients (mean age: 55.89±7.85 years) with knee osteoarthritis participated in the study. Patients completed the Turkish version of the Oxford Knee Score (OKS-TR), Short-Form 36 Health Survey (SF-36), and Western Ontario and McMaster Universities Index (WOMAC) questionnaires. Internal consistency was tested using Cronbach's α coefficient. Patients completed the OKS-TR questionnaire twice in 7 days to determine the reproducibility. Correlation between the total results of both tests was determined by Spearman's correlation coefficient and intraclass correlation coefficients (ICC). Validity was assessed by calculating Spearman's correlation coefficient between the OKS, WOMAC, and SF-36 scores. Floor and ceiling effects were analyzed. Internal consistency was high (Cronbach's α: 0.90). The reproducibility tested by 2 different methods showed no significant difference (p>0.05). The construct validity analyses showed a significant correlation between the OKS and the other scores (p<0.05). There was no floor or ceiling effect in total OKS score. The OKS-TR is a reliable and valid measure for the self-assessment of pain and function in Turkish-speaking patients with osteoarthritis of the knee.

Time course of the effects of orthokeratology on peripheral refraction and corneal topography.

PubMed

To describe the time course of changes in both peripheral refraction and corneal topography in myopic adults wearing myopic orthokeratology (OK) lenses. Nineteen adult myopes were fitted with OK lenses in both eyes for overnight wear. Central and peripheral refraction and corneal topography were measured along the horizontal meridian at baseline and after 1, 4, 7 and 14 nights of lens wear. At baseline, refraction was myopic at all positions along the horizontal meridian. Two weeks of OK lens wear caused a significant change in refraction where the general trend was a hyperopic shift in spherical equivalent (M) except at 35° in the nasal visual field where there was instead a myopic shift in M. The most significant change in M occurred between baseline and after 1 night of OK lens wear and the effect became less dramatic across subsequent days of OK treatment. Similarly, OK caused significant change in corneal refractive power at all positions along the horizontal corneal chord. There was a reduction in corneal power or flattening of the cornea at all positions except at 2.4 mm and 2.8 mm on the nasal cornea where there was an increase in corneal refractive power or steepening of the cornea. This change was most apparent after 1 night of OK lens wear and, similar to changes in peripheral refraction, changes in corneal refractive power on subsequent days of OK treatment became less marked. Orthokeratology caused significant changes in both peripheral refraction and corneal topography. The greatest change in refraction and corneal refractive power across the horizontal corneal meridian occurred during the first night of OK lens wear. Subsequent changes in both peripheral refraction and corneal topography were less dramatic, in the same manner as reported changes in apical radius and central refraction after OK. This study confirms that with OK treatment, the peripheral retina experiences myopic defocus, which is conjectured to underlie the observed slowing of myopia progression.

The aim of the study was to assess the effects of optokinetic stimulation (OKS) on vestibular postural control in migraine patients with recurrent vertigo. 15 patients with vestibular migraine (VM) were enrolled in a posturographic study in eyes open (OE) and eyes closed (CE) condition. The tests were performed between attacks of headache and vertigo at three different time: before, during, and 60 min after OKS. Data of patients with VM were compared with those obtained from two control groups matched for sex and age (15 for each group): (a) normal subjects not suffering from migraine without history of recurrent vertigo (N group); (b) subjects suffering from migraine with no history of recurrent vertigo (M group). Mean sway path velocity and sway area were analyzed. OKS increased the instability in all groups during the stimulus, and both the velocity and area values were higher in M and VM group. However, there was not significant difference between these two groups when stability was examined in OE condition before, during and after OKS stimulation. Conversely, in CE condition a significant greater instability was induced after OKS stimulation only in VM. In particular, post-stimulus values were significantly higher than the pre-stimulus one only in this group, while no significant difference was observed in other groups. A spatial analysis of the sway area evidenced that the instability induced by the OKS in VM group occurred along the direction of OKS. We suggest that this enhanced instability observed after OKS during the intercritical period may be considered an useful marker to support the diagnostic definition of VM in the absence of other vestibular signs.

To determine whether contact lenses designed for orthokeratology (OK) are colonized by greater numbers of bacteria compared with standard (alignment fitted) design rigid gas permeable lenses before and after lens wear. Eighteen 1-year-old cats were randomly fitted with an OK lens in one eye and an alignment fitted (AF) lens in the other eye. Both lenses were made in the same diameter and central thickness and of the same material. Two separate wearing periods of 2 weeks and 6 weeks were used. After each wearing period, lenses were soaked in Pseudomonas aeruginosa (6294 or 6206) for 10 min. The lenses were then reinserted onto their respective corneas for a wearing period of 16 hours after which lenses were collected and remaining adhered bacteria quantified. Unworn control lenses were also soaked and bacteria enumerated for comparison. There were no significant differences in the number of bacteria adherent to unworn AF and OK lenses. Analysis of lenses after wear showed OK lenses retained significantly higher numbers of viable bacteria than AF lenses in all studies. OK lenses retain more bacteria than AF rigid gas permeable lenses after bacteria-loaded overnight lens wear. This may increase the risk for an infection in OK patients should suitable conditions be present. Specific education on the cleaning of OK lenses is essential.

This study investigated the effect of socioeconomic deprivation on preoperative disease and outcome following unicompartmental knee replacement (UKR). 307 Oxford UKRs implanted between 2008 and 2013 under the care of one surgeon using the same surgical technique were analysed. Deprivation was quantified using the Northern Ireland Multiple Deprivation Measure. Preoperative disease severity and postoperative outcome were measured using the Oxford Knee Score (OKS). There was no difference in preoperative OKS between deprivation groups. Preoperative knee range of motion (ROM) was significantly reduced in more deprived patients with 10° less ROM than least deprived patients. Postoperatively there was no difference in OKS improvement between deprivation groups (p=0.46), with improvements of 19.5 and 21.0 units in the most and least deprived groups respectively. There was no significant association between deprivation and OKS improvement on unadjusted or adjusted analysis. Preoperative OKS, Short Form 12 mental component score and length of stay were significant independent predictors of OKS improvement. A significantly lower proportion of the most deprived group (15%) reported being able to walk an unlimited distance compared to the least deprived group (41%) one year postoperatively. More deprived patients can achieve similar improvements in OKS to less deprived patients following UKR. Copyright © 2015 Elsevier B.V. All rights reserved.

Code OK3 - An upgraded version of OK2 with beam wobbling function

Ogoyski, A. I.; Kawata, S.; Popov, P. H.

2010-07-01

For computer simulations on heavy ion beam (HIB) irradiation onto a target with an arbitrary shape and structure in heavy ion fusion (HIF), the code OK2 was developed and presented in Computer Physics Communications 161 (2004). Code OK3 is an upgrade of OK2 including an important capability of wobbling beam illumination. The wobbling beam introduces a unique possibility for a smooth mechanism of inertial fusion target implosion, so that sufficient fusion energy is released to construct a fusion reactor in future. New version program summaryProgram title: OK3 Catalogue identifier: ADST_v3_0 Program summary URL:http://cpc.cs.qub.ac.uk/summaries/ADST_v3_0.html Program obtainable from: CPC Program Library, Queen's University, Belfast, N.

Phys. Comm. 161 (2004) 143 Does the new version supersede the previous version?: Yes Nature of problem: In heavy ion fusion (HIF), ion cancer therapy, material processing, etc., a precise beam energy deposition is essentially important [1]. Codes OK1 and OK2 have been developed to simulate the heavy ion beam energy deposition in three-dimensional arbitrary shaped targets [2, 3]. Wobbling beam illumination is important to smooth the beam energy deposition nonuniformity in HIF, so that a uniform target implosion is realized and a sufficient fusion output energy is released. Solution method: OK3 code works on the base of OK1 and OK2 [2, 3]. The code simulates a multi-beam illumination on a target with arbitrary shape and structure, including beam wobbling function. Reasons for new version: The code OK3 is based on OK2 [3] and uses the same algorithm with some improvements, the most important one is the beam wobbling function. Summary of revisions:In the code OK3, beams are subdivided on many bunches. The displacement of each bunch center from the initial beam direction is calculated. Code OK3 allows the beamlet number to vary from bunch to bunch. That reduces the calculation error especially in case of very complicated mesh structure with big internal holes. The target temperature rises during the time of energy deposition. Some procedures are improved to perform faster. The energy conservation is checked up on each step of calculation process and corrected if necessary. New procedures included in OK3 Procedure BeamCenterRot( ) rotates the beam axis around the impinging direction of each beam. Procedure BeamletRot( ) rotates the beamlet axes that belong to each beam. Procedure Rotation( ) sets the coordinates of rotated beams and beamlets in chamber and pellet systems. Procedure BeamletOut( ) calculates the lost energy of ions that have not impinged on the target. Procedure TargetT( ) sets the temperature of the target layer of energy deposition during the irradiation process. Procedure ECL( ) checks up the energy conservation law at each step of the energy deposition process. Procedure ECLt( ) performs the final check up of the energy conservation law at the end of deposition process. Modified procedures in OK3 Procedure InitBeam( ): This procedure initializes the beam radius and coefficients A1, A2, A3, A4 and A5 for Gauss distributed beams [2]. It is enlarged in OK3 and can set beams with radii from 1 to 20 mm. Procedure kBunch( ) is modified to allow beamlet number variation from bunch to bunch during the deposition. Procedure ijkSp( ) and procedure Hole( ) are modified to perform faster. Procedure Espl( ) and procedure ChechE( ) are modified to increase the calculation accuracy. Procedure SD( ) calculates the total relative root-mean-square (RMS) deviation and the total relative peak-to-valley (PTV) deviation in energy deposition non-uniformity. This procedure is not included in code OK2 because of its limited applications (for spherical targets only). It is taken from code OK1 and modified to perform with code OK3. Running time: The execution time depends on the pellet mesh number and the number of beams in the simulated illumination as well as on the beam characteristics (beam radius on the pellet surface, beam subdivision, projectile particle energy and so on). In almost all of the practical running tests performed, the typical running time for one beam deposition is about 30 s on a PC with a CPU of Pentium 4, 2.4 GHz. References:A.I.

Optokinetic and Vestibular Responsiveness in the Macaque Rostral Vestibular and Fastigial Nuclei

Bryan, Ayanna S.; Angelaki, Dora E.

2009-01-01

We recorded from rostral vestibular (VN) and rostral fastigial nuclei (FN) neurons that did not respond to eye movements during three-dimensional (3D) vestibular and optokinetic stimulation (OKS). The majority of neurons in both areas (76 and 69% in VN and FN, respectively) responded during both rotational and translational motion. Preferred directions scattered throughout 3D space for translation but showed some preference for pitch/roll over yaw for rotation. VN/FN neurons were also tested during OKS while monkeys suppressed their optokinetic nystagmus by fixating a head-fixed target. Only a handful of cells (VN: 17%, FN: 6%) modulated during 0.5-Hz OKS suppression, but the number of responsive cells increased (VN: 40%, FN: 48%) during 0.02-Hz OKS. Preferred directions for rotation and OKS were not matched on individual neurons, and OKS gains were smaller than the respective gains during rotation. These results were generally similar for VN and FN neurons. We conclude that optokinetic-vestibular convergence might not be as prevalent as earlier studies have suggested. PMID:19073813

To investigate changes in peripheral refraction, corneal topography, and aberrations induced by changes in orthokeratology (OK) lens parameters in myopes. Subjects were fitted with standard OK lenses that were worn overnight for 2 weeks. Peripheral refraction, corneal topography, and corneal surface aberrations were measured at baseline and after 14 nights of OK lens wear. Subsequent to a 2-week washout period, subjects were refitted with another set of lenses where one eye was randomly assigned to wear an OK lens with a smaller optic zone diameter (OZD) and the other eye with a steeper peripheral tangent. Measurements were taken again at a second baseline and after 14 days of overnight wear of the second OK lens set. Standard OK lenses with a 6-mm OZD and 1/4 peripheral tangent caused significant changes in both peripheral refraction and corneal topography. Significant hyperopic shift occurred in the central visual field (VF) while a myopic shift was found at 35 degrees in the nasal VF. OK induced significant reductions in corneal power at all positions along the horizontal corneal chord except at 2.4 mm nasal where there was no significant change and at 2.8 mm nasal where there was an increase in corneal refractive power. A positive shift in spherical aberration was induced for all investigated lens designs except for the 1/2 tangent design when calculated over a 4-mm pupil. Reducing OZD and steepening the peripheral tangent did not cause significant changes in peripheral refraction or corneal topography profiles across the horizontal meridian. OK lenses caused significant changes in peripheral refraction, corneal topography, and corneal surface aberrations. Modifying OZD and peripheral tangent made no significant difference to the peripheral refraction or corneal topography profile. Attempting to customize refraction and topography changes through manipulation of OK lens parameters appears to be a difficult task.

Vasoactive peptides are key early mediators of inflammation released through activation of different enzymatic systems. The mammalian kinin-kallikrein (K-KLK) system produces bradykinin (BK) through proteolytic cleavage of a kininogen precursor by enzymes named kallikreins. BK acts through specific ubiquitous G-protein coupled receptors (B1R and B2R) to participate in physiological processes and inflammatory responses, such as activation of mononuclear phagocytes. In chickens, the BK-like nonapeptide ornithokinin (OK) has been shown to promote intracellular calcium increase in embryonic fibroblasts and to be vasodilatory in vivo. Also, one of its receptors (B2R) was already cloned. However, the participation of chicken K-KLK system components in the inflammatory response remains unknown and was therefore investigated. We first showed that B1R, B2R and kininogen 1 (KNG1) are expressed in unstimulated chicken tissues and macrophages. We next showed that chicken B1R and B2R are expressed at transcript and protein levels in chicken macrophages and are upregulated by E. coli LPS or avian pathogenic E. coli (APEC) infection. Interestingly, exogenous OK induced internalization and degradation of OK receptors protein, notably B2R. Also, OK induced intracellular calcium increase and potentiated zymosan-induced ROS production and Dextran-FITC endocytosis by chicken macrophages. Exogenous OK itself did not promote APEC killing and had no pro-inflammatory effect. However, when combined with LPS or APEC, OK upregulated cytokine/chemokine gene expression and NO production by chicken macrophages. This effect was not blocked by canonical non-peptide B1R or B2R receptor antagonists but was GPCR- and PI3K/Akt-dependent. In vivo, pulmonary colibacillosis led to upregulation of OK receptors expression in chicken lungs and liver. Also, colibacillosis led to significant upregulation of OK precursor KNG1 expression in liver and in cultured hepatocytes (LMH). We therefore provide hitherto unknown information on how OK and its receptors are involved in inflammation and infection in chickens. Copyright © 2017 Elsevier B.V. All rights reserved.

Performance comparison of LUR and OK in PM2.5 concentration mapping: a multidimensional perspective

Methods of Land Use Regression (LUR) modeling and Ordinary Kriging (OK) interpolation have been widely used to offset the shortcomings of PM2.5 data observed at sparse monitoring sites. However, traditional point-based performance evaluation strategy for these methods remains stagnant, which could cause unreasonable mapping results. To address this challenge, this study employs ‘information entropy’, an area-based statistic, along with traditional point-based statistics (e.g. error rate, RMSE) to evaluate the performance of LUR model and OK interpolation in mapping PM2.5 concentrations in Houston from a multidimensional perspective. The point-based validation reveals significant differences between LUR and OK at different test sites despite the similar end-result accuracy (e.g. error rate 6.13% vs. 7.01%). Meanwhile, the area-based validation demonstrates that the PM2.5 concentrations simulated by the LUR model exhibits more detailed variations than those interpolated by the OK method (i.e. information entropy, 7.79 vs. 3.63). Results suggest that LUR modeling could better refine the spatial distribution scenario of PM2.5 concentrations compared to OK interpolation. The significance of this study primarily lies in promoting the integration of point- and area-based statistics for model performance evaluation in air pollution mapping. PMID:25731103

The Oxford Knee Score (OKS) is a short patient-reported outcome instrument that measures pain and physical activity related to knee osteoarthritis. The purpose of this study is to evaluate, construct validity and consistent reliability of the Persian version of the OKS. The case series consisted of 80 patients who were clinically diagnosed with having knee osteoarthritis. All patients were requested to fill-in the Persian OKS and Short-Form 36 Health Survey (SF-36). Correlation analysis between the Persian versions of these two instruments was then carried out. The scores of the Persian SF-36 were used to evaluate convergent and divergent validity of the 12-item Persian OKS. From a total of 80 patients, 63 were female (79%) and the remaining 17 were male (21%) with a mean age of 52.2 years. In the present study, high Cronbach's alpha of 0.95 confirms excellent internal consistency of the Persian OKS scale similar to previous investigations. The results confirm that the Persian version of this instrument is valid and reliable, similar to its English index and its subsequent translations in different languages. The Persian OKS is a reliable instrument to evaluate knee function in patients with knee osteoarthritis and is a useful tool for outcome measurement in clinical research.

There are varieties of self-assessment questionnaire used for the evaluation of pain, functional disability, and health related quality of life in individuals with knee osteoarthritis (OA). The present study intended to adapt and translate the oxford knee score into the Arabic and investigated its psychometric properties in adult male with knee OA. Ninety-seven adult male (mean age 57.55 ± 11.49 years) with knee OA participated. Patients were requested to complete the adapted Arabic version of the Oxford knee score (OKS-Ar), reduced "Western Ontario and McMaster Universities Index (WOMAC)", and the Visual analogue scale (VAS). Patients were requested to complete 2 nd form of OKS-Ar at least 1 week apart to assess the reproducibility of the score. The OKS was adapted and translated into Arabic by two independent Arabic native speakers (one rehabilitation professional having experience of knee OA patients and another one a trained translator) according to the international guidelines. All the participants completed the 2 nd form of OKS-Ar (Response rate 100%). Reliability and internal consistency was high with an ICC of 0.97, and the Cronbach's alpha coefficient of 0.987, respectively. A significant relationship between the OKS-Ar and the WOMAC and VAS scores confirmed the construct validity (p < 0.001). The standard error of measurement (SEM) and the minimum detectable change (MDC) were 2.2 and 6.2, respectively. The adapted Arabic version of the OKS demonstrated acceptable psychometric properties, including reliability, internal consistency, and the validity. The present study indicates that the OKS-Ar is a suitable questionnaire to measure pain and physical function in the Arabic speaking adult male patients with knee OA.

A small proportion of patients with mobile unicompartmental knee arthroplasty (UKA) report poor functional outcomes in spite of optimal component alignment on postoperative radiographs. The purpose of this study is to assess whether there is a correlation between functional outcome and knee kinematics. From a cohort of consecutive cases of 150 Oxford medial UKA, patients with fair/poor functional outcome at 1-year postsurgery (Oxford Knee Score [OKS] < 34, n = 15) were identified and matched for age, gender, preoperative clinical scores, and follow-up period with a cohort of patients with good/excellent outcome (OKS ≥ 34, n = 15). In vivo kinematic assessment was performed using step-up and deep knee bend exercises under fluoroscopic imaging. The fluoroscopic videos were analyzed using MATLAB software to measure the variation in time taken to complete the exercises, patellar tendon angle, and bearing position with knee flexion angle. Mean OKS in the fair/poor group was 29.9 and the mean OKS in the good/excellent group was 41.1. The tibial slope, time taken to complete the exercises, and patellar tendon angle trend over the flexion range were similar in both the groups; however, bearing position and the extent of bearing excursion differed significantly. The total bearing excursion in the OKS < 34 group was significantly smaller than the OKS ≥ 34 group (35%). Furthermore, on average, the bearing was positioned 1.7 mm more posterior on the tibia in the OKS < 34 group. This study provides evidence that abnormal knee kinematics, in particular bearing excursion and positioning, are associated with worse functional outcomes after mobile UKA.

Preoperative transarterial immunoembolization (TIE) for hepatocellular carcinoma (HCC) is effective for preventing recurrence. We aimed to investigate the intratumoral and peritumoral M1 macrophage-induced immune response following TIE treatment. We compared 13 patients treated with TIE between 2003 and 2009 (TIE group) and 13 patients treated with surgery alone during the same period of time at our institute (control group) using an immunohistological study with CD68 and CD163 antibodies. No significant differences in clinicopathological characteristics, except for surgical time, were observed between the two groups. The 3-year recurrence-free survival outcome of the TIE group was quite different from that of the control group (100% vs. 38.5%, P = 0.034). In the histological investigation, lytic necrosis and coagulation necrosis of the main tumor along with the presence of multinuclear giant cells were observed in 10 of the 13 patients in the TIE group. The immunohistological study showed that not only the numbers of intratumoral CD68(+) cells, but also the numbers of intratumoral and peritumoral CD8(+) cells were significantly increased in the TIE group. The suppression of tumor recurrence induced by preoperative TIE might be induced by intratumoral M1 macrophages that are activated by OK-432 and fibrinogen. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

The American Knee Society score (AKSS) and the Oxford Knee score (OKS) are validated outcome measures for evaluation of total knee arthroplasties (TKAs). We investigated whether patient self-assessment using the OKS offers a viable alternative to clinical review using the AKSS. Preoperative, 2-year, 5-year, and 10-year postoperative OKS and AKSS were reviewed from TKA patients. The scores were analyzed using the Pearson correlation. There was good correlation of OKS and AKSS at 2 years. This implies that patient self-assessment is a viable screening tool to identify which patients require clinical review, at 2 years, after TKA. However, the moderate correlation at 5 and 10 years indicates that clinical evaluation remains necessary at these time points.

Evaluation of spatial and spatiotemporal estimation methods in simulation of precipitation variability patterns

NASA Astrophysics Data System (ADS)

Bayat, Bardia; Zahraie, Banafsheh; Taghavi, Farahnaz; Nasseri, Mohsen

2013-08-01

Identification of spatial and spatiotemporal precipitation variations plays an important role in different hydrological applications such as missing data estimation. In this paper, the results of Bayesian maximum entropy (BME) and ordinary kriging (OK) are compared for modeling spatial and spatiotemporal variations of annual precipitation with and without incorporating elevation variations. The study area of this research is Namak Lake watershed located in the central part of Iran with an area of approximately 90,000 km2. The BME and OK methods have been used to model the spatial and spatiotemporal variations of precipitation in this watershed, and their performances have been evaluated using cross-validation statistics. The results of the case study have shown the superiority of BME over OK in both spatial and spatiotemporal modes. The results have shown that BME estimates are less biased and more accurate than OK. The improvements in the BME estimates are mostly related to incorporating hard and soft data in the estimation process, which resulted in more detailed and reliable results. Estimation error variance for BME results is less than OK estimations in the study area in both spatial and spatiotemporal modes.

Seismogenic response to fluid injection operations in Oklahoma and California: Implications for crustal stresses

NASA Astrophysics Data System (ADS)

Goebel, T.; Aminzadeh, F.

2015-12-01

The seismogenic response to induced pressure changes provides insight into the proximity to failure of faults close to injection sites. Here, we examine possible seismicity rate changes in response to wastewater disposal and enhanced oil recovery operations in hydrocarbon basins in California and Oklahoma. We test whether a statistically significant rate increase exists within these areas and determine the corresponding timing and location based on nonparametric modeling of background seismicity rates. Annual injection volumes increased monotonically since ~2001 in California and ~1998 in Oklahoma. While OK experienced a recent surge in seismic activity which exceeded the 95% confidence limit of a stationary Poisson process in ~2010, seismicity in CA showed no increase in background rates between 1980 and 2014. A systematic analysis of frequency-magnitude-distributions (FMDs) of likely induced earthquakes in OK indicates that FMDs are depleted in large-magnitude events. Seismicity in CA hydrocarbon basins, on the other hand, shows Gutenberg-Richter type FMDs and b~1. Moreover, the earthquakes and injection operations occur preferably in distinct areas in CA whereas in OK earthquakes occur closer to injection wells than expected from a random uniform process. To test whether injection operations may be responsible for the strongly different seismicity characteristics in CA and OK, we compare overall well density, wellhead pressures, peak and cumulative rates as well as injection depths. We find that average injection rates, pressures and volumes are comparable between CA and OK and that injection occurs on average 0.5 km deeper in CA than in OK. Thus, the here tested operational parameters can not easily explain the vastly different seismogenic response to injection operations in CA and OK, and may only be of secondary importance for the resulting earthquake activity. The potential to induce earthquakes by fluid injection operations is likely controlled by the specific geologic setting and stress state on nearby faults.

Optokinetic and vestibular stimulation determines the spatial orientation of negative optokinetic afternystagmus in the rabbit.

Prolonged binocular optokinetic stimulation (OKS) in the rabbit induces a high-velocity negative optokinetic afternystagmus (OKAN II) that persists for several hours. We have taken advantage of this uniform nystagmus to study how changes in static head orientation in the pitch plane might influence the orientation of the nystagmus. After horizontal OKS, the rotation axis of the OKAN II remained almost constant in space as it was kept aligned with the gravity vector when the head was pitched by as much as 80 degrees up and 35 degrees down. Moreover, during reorientation, slow-phase eye velocity decreased according to the head pitch angle. Thereafter, we analyzed the space orientation of OKAN II after optokinetic stimulation during which the head and/or the OKS were pitched upward and downward. The rotation axis of OKAN II did not remain aligned with an earth vertical axis nor a head vertical axis, but it tended to be aligned with that of the OKS respace. The slow-phase eye velocity of OKAN II was also affected by the head pitch angle during OKS, because maximal OKAN II velocity occurred at the same head pitch angle as that during optokinetic stimulation. We suggest that OKAN II is coded in gravity-centered rather than in head-centered coordinates, but that this coordinate system may be influenced by optokinetic and vestibular stimulation. Moreover, the velocity attenuation of OKAN II seems to depend on the mismatch between the space-centered nystagmus rotation axis orientation and that of the "remembered" head-centered optokinetic pathway activated by OKS.

With the increasing number of patients with knee osteoarthritis undergoing TKAs in China, there is a clear need for a valid, short, joint-specific patient-reported outcome measure such as the Oxford Knee Score (OKS). To test the translated and cross-culturally adapted Chinese (Mandarin) version of the Oxford Knee Score (OKS-CV) and its (1) reliability, (2) construct validity, (3) dimensionality, and (4) responsiveness. Three native Chinese bilingual translators (a professional English translator, an experienced orthopaedic surgeon, an advanced-practice nursing specialist) translated the English-language OKS into Mandarin Chinese. A consensus panel created a synthesis of those efforts, which then was back-translated by two bilingual nonmedical, professional English-language translators. The OKS-CV was developed according to the guidelines of copyright holders. Between March 2013 and March 2015, 253 patients underwent TKAs. Among them, 114 Mandarin-speaking patients with knee osteoarthritis underwent primary unilateral TKA (age, 67 ± 7 years; range, 55-84 years; female, 80%; preoperatively 54% had moderate to severe knee osteoarthritis), completed the preoperative questionnaires, and were followed up, with a mean postoperative followup of 2.7 years (SD, 0.5 years). Eligibility criteria were (1) patients with knee osteoarthritis who were scheduled to have a primary unilateral TKA, (2) patients who were fluent in Mandarin, and (3) consent to participate. The exclusion criteria were: (1) lack of understanding of Mandarin, and (2) inability to comprehend the questionnaires owing to cognitive impairment. To evaluate test-retest reliability, another group of 35 Mandarin-speaking outpatients with knee osteoarthritis (age, 61 ± 10 years; range, 44-84 years; female, 77%) was recruited to complete the OKS-CV twice at a 1-week interval. Reliability was tested using Cronbach's alpha and intraclass correlation coefficient (ICC). Construct validity was evaluated using Spearman's rank correlation coefficient to quantify the correlations between the OKS-CV and the WOMAC, Short Form-8 Health Survey (SF-8 TM ), and EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D). Exploratory factor analysis was performed to clarify dimensionality. The eigenvalue indicates the importance of each factor obtained from factor analysis. Responsiveness was determined by standardized response mean (SRM) and effect size (ES) from preoperative and postoperative scores of the OKS-CV. Floor and ceiling effects also were analyzed. The internal consistency (Cronbach's alpha = 0.89) and test-retest reliability (ICC = 0.93; 95% CI, 0.87-0.97) proved good. Convergent construct validity was supported by moderate to strong correlations between the OKS-CV and the WOMAC (r = -0.80, p < 0.001), the SF-8 TM physical component summary (r = 0.65, p < 0.001), and the EQ-5D usual activities (r = -0.41, p < 0.001) and mobility (r = -0.35, p < 0.001). There also were correlations between the OKS-CV and the SF-8 TM mental component summary (r = 0.58, p < 0.001) and the EQ-5D anxiety/depression (r = -0.35, p < 0.001). The factor analysis yielded three factors with eigenvalues greater than 1. Responsiveness was excellent (SRM = 1.52; ES = 1.52). No floor or ceiling effect was observed. The OKS-CV showed good acceptability and psychometric properties for the intended population. Future studies are needed to evaluate the mental state of patients with knee osteoarthritis. The OKS-CV appears to be a reliable, valid, and responsive instrument for Chinese patients with knee osteoarthritis. Based on these results we believe the OKS-CV can be used as a valuable tool for the assessment of patient-reported outcomes in Chinese patients with knee osteoarthritis before and after TKA.

2011-06-01

To examine the morphological and biometric corneal changes produced over periods of 15 days and 1 month after overnight orthokeratology (OK). Prospective, single-center, longitudinal trial. Twenty-seven right eyes of 27 subjects (group 1) with low to moderate myopia wore OK lenses for 1 month. Ten right eyes of 10 subjects (group 2) with emmetropia to low myopia who did not wear any type of contact lens served as controls. Corneal morphometric measurements were obtained in vivo using a confocal microscope to examine the central and midperipheral cornea. Thickness measurements in the peripheral cornea were obtained by optical coherence tomography. Changes in visual acuity, refractive error, and corneal topography were also analyzed. No significant changes in either endothelial cell or stromal cell density were observed after 1 month of OK. Basal epithelial cells were, however, significantly reduced (P < 0.01), and epithelial wing and superficial cells showed enhanced visibility (P < 0.05). Superficial cells increased in height and width, the width increase after 1 month being significant (P < 0.01). Epithelial thickness was significantly reduced in the central cornea and 2 mm around the center. Corneal pachymetry increased significantly in the band from 5 to 10 mm from the corneal apex (P < 0.01). OK lenses for myopia induce significant structural and optical changes particularly in the central epithelium after 15 days or 1 month of wear. The central corneal epithelium responds to OK wear by undergoing significant epithelial cell shape and size alterations with no effects, however, on the cells of the corneal endothelium or the corneal stroma. Peripheral corneal thickness increased with respect to baseline values. These findings suggest that the corneal epithelium is the principal structure affected by the mechanical forces exerted by the OK lenses.

Localization of the Calcium Regulated Citrate Transport Process in Proximal Tubule Cells

Urinary citrate is an important inhibitor of calcium stone formation. Most of citrate reabsorption in the proximal tubule is thought to occur via a dicarboxylate transporter NaDC1 located in the apical membrane. OK cells, an established opossum kidney proximal tubule cell line, transport citrate but the characteristics change with extracellular calcium such that low calcium solutions stimulate total citrate transport as well as increase the apparent affinity for transport. The present studies address several fundamental properties of this novel process: the polarity of the transport process, the location of the calcium-sensitivity and whether NaDC1 is present in OK cells. OK cells grown on permeable supports exhibited apical > basolateral citrate transport. Apical transport of both citrate and succinate was sensitive to extracellular calcium whereas basolateral transport was not. Apical calcium, rather than basolateral, was the predominant determinant of changes in transport. Also 2,3-dimethylsuccinate, previously identified as an inhibitor of basolateral dicarboxylate transport, inhibited apical citrate uptake. Although the calcium-sensitive transport process in OK cells is functionally not typical NaDC1, NaDC1 is present in OK cells by Western blot and PCR. By immunolocalization studies, NaDC1 was predominantly located in discrete apical membrane or subapical areas. However by biotinylation, apical NaDC1 decreases in the apical membrane with lowering calcium. In sum, OK cells express a calcium-sensitive/regulated dicarboxylate process at the apical membrane which responds to variations in apical calcium. Despite the functional differences of this process compared to NaDC1, NaDC1 is present in these cells, but predominantly in subapical vesicles. PMID:24652587

Balance disorder and increased risk of falls in osteoporosis and kyphosis: significance of kyphotic posture and muscle strength.

This controlled trial was designed to investigate the influence of osteoporosis-related kyphosis (O-K) on falls. Twelve community-dwelling women with O-K (Cobb angle, 50-65 degrees measured from spine radiographs) and 13 healthy women serving as controls were enrolled. Mean age of the O-K group was 76 years (+/-5.1), height 158 cm (+/-5), and weight 61 kg (+/-7.9), and mean age of the control group was 71 years (+/-4.6), height 161 cm (+/-3.8), and weight 66 kg (+/-11.7). Quantitative isometric strength data were collected. Gait was monitored during unobstructed level walking and during stepping over an obstacle of four different heights randomly assigned (2.5%, 5%, 10%, and 15% of the subject's height). Balance was objectively assessed with computerized dynamic posturography consisting of the sensory organization test. Back extensor strength, grip strength, and all lower extremity muscle groups were significantly weaker in the O-K group than the control group (P <0.05), except right ankle plantar flexors (P =0.09). There was a significant difference in the anteroposterior and mediolateral displacements and velocities. The O-K subjects had less anteroposterior displacement, greater mediolateral displacement, reduced anteroposterior velocity, and increased mediolateral velocity compared with controls for all conditions of unobstructed and obstructed level walking. Obstacle height had a significant effect on all center-of-mass variables. The O-K subjects had significantly greater balance abnormalities on computerized dynamic posturography than the control group (P =0.002). Data show that thoracic hyperkyphosis on a background of reduced muscle strength plays an important role in increasing body sway, gait unsteadiness, and risk of falls in osteoporosis.

Initial application of a dual-sweep streak camera to the Duke storage ring OK-4 source

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lumpkin, A.H.; Yang, B.X.; Litvinenko, V.

1997-08-01

The visible and UV spontaneous emission radiation (SER) from the Duke OK-4 wiggler has been used with a Hamamatsu C5680 dual-sweep streak camera to characterize the stored electron beams. Particle beam energies of 270 and 500 MeV in the Duke storage ring were used in this initial application with the OK-4 adjusted to generate wavelengths from 500 nm to near 200 nm. The OK-4 magnetic system with its 68 periods provided a much stronger radiation source than a nearby bending magnet source point. Sensitivity to single-bunch, single-turn SER was shown down to 4 {mu}A beam current at {lambda} = 450more » nm. The capability of seeing second passes in the FEL resonator at a wavelength near 200 nm was used to assess the cavity length versus orbit length. These tests (besides supporting preparation for UV-visible SR FEL startups) are also relevant to possible diagnostics techniques for single-pass FEL prototype facilities.« less

We previously reported that the anti-tumour effect of OK-432 is considerably enhanced by its intratumoral injection together with fibrinogen. In the present study, we generated killer T cells by culturing tumour-infiltrating lymphocytes from thyroid cancer patients who had received this local immunotherapy. Phenotypic analysis revealed that the T cells were positive for CD3+, CD4+, Leu8-, CD45RO+ and T-cell receptor (TCR)alpha beta+, as well as showing strong surface expression of HLA-DR, CD25, LFA-1 and ICAM-1. The generated CD4+ T cells secreted interferon (IFN)-gamma, tumour necrosis factor (TNF)-alpha, TNF-beta, and interleukin (IL)-6 (but not IL-4), and exhibited a high level of cytolytic activity against several tumour cell lines. The cytolytic activity of these T cells for Daudi cells was inhibited by preincubation with an anti-intercellular adhesion molecule (ICAM)-1 antibody, but not by preincubation with anti-TCR alpha beta, anti-CD2, or anti-LFA-1 antibodies. Pretreatment with anti-ICAM-1 antibody inhibited T-cell cytolytic activity, but not conjugation with target cells. In addition, incubation with immobilised anti-ICAM-1 enhanced the secretion of IFN-gamma by T cells. We conclude that ICAM-1 expressed on the effector cytotoxic CD4+ T lymphocytes delivers regulatory signals that enhance IFN-gamma secretion. PMID:8554971

Estimating the spatial distribution of soil moisture based on Bayesian maximum entropy method with auxiliary data from remote sensing

Soil moisture (SM) plays a fundamental role in the land-atmosphere exchange process. Spatial estimation based on multi in situ (network) data is a critical way to understand the spatial structure and variation of land surface soil moisture. Theoretically, integrating densely sampled auxiliary data spatially correlated with soil moisture into the procedure of spatial estimation can improve its accuracy. In this study, we present a novel approach to estimate the spatial pattern of soil moisture by using the BME method based on wireless sensor network data and auxiliary information from ASTER (Terra) land surface temperature measurements. For comparison, three traditional geostatistic methods were also applied: ordinary kriging (OK), which used the wireless sensor network data only, regression kriging (RK) and ordinary co-kriging (Co-OK) which both integrated the ASTER land surface temperature as a covariate. In Co-OK, LST was linearly contained in the estimator, in RK, estimator is expressed as the sum of the regression estimate and the kriged estimate of the spatially correlated residual, but in BME, the ASTER land surface temperature was first retrieved as soil moisture based on the linear regression, then, the t-distributed prediction interval (PI) of soil moisture was estimated and used as soft data in probability form. The results indicate that all three methods provide reasonable estimations. Co-OK, RK and BME can provide a more accurate spatial estimation by integrating the auxiliary information Compared to OK. RK and BME shows more obvious improvement compared to Co-OK, and even BME can perform slightly better than RK. The inherent issue of spatial estimation (overestimation in the range of low values and underestimation in the range of high values) can also be further improved in both RK and BME. We can conclude that integrating auxiliary data into spatial estimation can indeed improve the accuracy, BME and RK take better advantage of the auxiliary information compared to Co-OK, and BME outperforms RK by integrating the auxiliary data in a probability form.

To characterize the axial and off-axis refraction across four meridians of the retina in myopic eyes before and after Orthokeratology (OK) and LASIK surgery. Sixty right eyes with a spherical equivalent (M) between - 0.75 to - 5.25 D (cylinder <- 1.00 D) underwent LASIK (n = 26) or OK (n = 34) to treat myopia. Axial and off-axis refraction were measured with an open-field autorefractometer before and after stabilized treatments. Off-axis measurements were obtained for the horizontal (35° nasal and temporal retina) and vertical (15° superior and inferior retina) meridians, and for two oblique directions (45-225° and 135-315°) up to 20° of eccentricity. The refractive profile was addressed as relative peripheral refractive error (RPRE). OK and LASIK post-treatment results showed an increase of myopic relative refraction at several eccentric locations. At the four meridians evaluated, the M component of the pre-treatment RPRE values was not statistically different ( p > 0.05) from the post-treatment RPRE within 30° and 20° of the central visual field after LASIK and OK, respectively. These results demonstrated that the treatment zone warrants an optimal central field of vision. The present study gives an overview of RPRE after refractive corneal reshaping treatments (OK and LASIK) across vertical, horizontal and two oblique meridians together. This allows a 3D representation of RPRE at the retina and shows that the myopic shift induced by both treatments is more relevant in horizontal directions.

Natural vestibular and optokinetic stimulation were used to investigate the possible role of the cerebellar nodulus in the regulation and modification of reflexive eye movements in rabbits. The nodulus and folium 9d of the uvula were destroyed by surgical aspiration. Before and after nodulectomy the vertical and horizontal vestibuloocular reflexes (VVOR, HVOR) were measured during sinusoidal vestibular stimulation about the longitudinal (roll) and vertical (yaw) axes. Although the gain of the HVOR (G(HVOR) = peak eye movement velocity/peak head velocity) was not affected by the nodulectomy, the gain of the VVOR (G(VVOR)) was reduced. The gains of the vertical and horizontal optokinetic reflexes (G(VOKR), G(HOKR)) were measured during monocular, sinusoidal optokinetic stimulation (OKS) about the longitudinal and vertical axes. Following nodulectomy, there was no reduction in G(VOKR) or G(HOKR). Long-term binocular OKS was used to generate optokinetic afternystagmus, OKAN II, that lasts for hours. After OKAN II was induced, rabbits were subjected to static pitch and roll, to determine how the plane and velocity of OKAN II is influenced by a changing vestibular environment. During static pitch, OKAN II slow phase remained aligned with earth-horizontal. This was true for normal and nodulectomized rabbits. During static roll, OKAN II remained aligned with earth-horizontal in normal rabbits. During static roll in nodulectomized rabbits, OKAN II slow phase developed a centripetal vertical drift. We examined the suppression and recovery of G(VVOR) following exposure to conflicting vertical OKS for 10-30 min. This vestibular-optokinetic conflict reduced G(VVOR) in both normal and nodulectomized rabbits. The time course of recovery of G(VVOR) after conflicting OKS was the same before and after nodulectomy. In normal rabbits, the head pitch angle, at which peak OKAN II velocity occurred, corresponded to the head pitch angle maintained during long-term OKS. If the head was maintained in a "pitched-up" or "pitched-down" orientation during long-term OKS, the subsequently measured OKAN II peak velocity occurred at the same orientation. This was not true for nodulectomized rabbits, who had OKAN II peak velocities at head pitch angles independent of those maintained during long-term OKS. We conclude that the nodulus participates in the regulation of compensatory reflexive movements. The nodulus also influences "remembered" head position in space derived from previous optokinetic and vestibular stimulation.

[Aleksandr Lwowicz Blok (1852 - 1909)--character-sketch of the man and scientist].

The article is an attempt of a new outlook first of all upon scientific output of many years' (the years 1878 - 1909) lecturer on Russian State Law in the Imperial University of Warsaw--Aleksandr Lwowicz Błok. Historians of literature, researchers of life and output of the scientist's son, an eminent poet-symbolist Aleksandr A. Błok, to a high degree were able to reconstruct lot of life and vicissitudes of the Warsaw professor. Thanks to the preserved university archival materials it was possible to add many details to Błok's biography, especially concerning his professional problems. They were connected with dramatic events in personal life of the professor. According to relations of the part of his university co-workers and students, the circumstances even brought about the symptoms of the mental illness. Prematurely elderly he was a man deeply miserable, lonely and deprived of understanding by associates. Up till now his scientific output has not been described precisely enough. Not numerous memories of his contemporaries (Szymon Askenazy, Nikołaj Dubrowskij) and even inconspicuous modern researches of the Polish (Janusz Woliński) brought about, in the author's opinion, too simplified and schematic character-sketch of Błok as a Russificator and nationalist, mediocre scholar and much worse lecturer. A scientific output of Błok is, indeed, inostensible--he published 2 books only--Master's thesis entitled: Władza państwowa w społeczeństwie europejskim. Poglad na polityczna teorie Lorenza Steina i na francuska rzeczywistość polityczna (1880) [State Authority in European Society. Outlook upon Political Theory of Lorenz Stein and French Political Facts (1880)] and Literatura polityczna w Rosj i o Rosji (1884) [Political Literature in Russia and on Russia (1884)] as an introduction to his course in State Law. Two thirds, so over 20 years of work, he gave to the not accomplished conception of creating a new classification of sciences that together with its assumptions was included in work of Blok's disciple--Jewgienij Spektorski. An attempt of objective, free of emotions look at Błok's output to some extent makes us verify one-sidedly its critical estimate. In Błok's writings one can observe several earlier unnoticed values--author's wide mind horizons, his erudition, interesting but not accomplished research conceptions, competence for analysing difficult issues fringing upon social, political and philosophical thought.

Dendritic cells (DCs) can be successfully generated from leukemic blasts in individual patients with AML or MDS: an evaluation of different methods.

Myeloid-leukemic cells (AML, MDS, CML) can be differentiated to leukemia-derived dendritic cell [DC (DCleu)] potentially presenting the whole leukemic antigen repertoire without knowledge of distinct leukemia antigens and are regarded as promising candidates for a vaccination strategy. We studied the capability of 6 serum-free DC culture methods, chosen according to different mechanisms, to induce DC differentiation in 137 cases of AML and 52 cases of MDS. DC-stimulating substances were cytokines ("standard-medium", "MCM-Mimic", "cytokine-method"), bacterial lysates ("Picibanil"), double-stranded RNA ["Poly (I:C)"] or a cytokine bypass method ("Ca-ionophore"). The quality/quantity of DC generated was estimated by flow cytometry studying (co) expressions of "DC"antigens, costimulatory, maturation, and blast-antigens. Comparing these methods on average 15% to 32% DC, depending on methods used, could be obtained from blast-containing mononuclear cells (MNC) in AML/MDS cases with a DC viability of more than 60%. In all, 39% to 64% of these DC were mature; 31% to 52% of leukemic blasts could be converted to DCleu and DCleu-proportions in the suspension were 2% to 70% (13%). Average results of all culture methods tested were comparable, however not every given case of AML could be differentiated to DC with 1 selected method. However performing a pre-analysis with 3 DC-generating methods (MCM-Mimic, Picibanil, Ca-ionophore) we could generate DC in any given case. Functional analyses provided proof, that DC primed T cells to antileukemia-directed cytotoxic cells, although an anti-leukemic reaction was not achieved in every case. In summary our data show that a successful, quantitative DC/DCleu generation is possible with the best of 3 previously tested methods in any given case. Reasons for different functional behaviors of DC-primed T cells must be evaluated to design a practicable DC-based vaccination strategy.

Mapping soil particle-size fractions: A comparison of compositional kriging and log-ratio kriging

NASA Astrophysics Data System (ADS)

Wang, Zong; Shi, Wenjiao

2017-03-01

Soil particle-size fractions (psf) as basic physical variables need to be accurately predicted for regional hydrological, ecological, geological, agricultural and environmental studies frequently. Some methods had been proposed to interpolate the spatial distributions of soil psf, but the performance of compositional kriging and different log-ratio kriging methods is still unclear. Four log-ratio transformations, including additive log-ratio (alr), centered log-ratio (clr), isometric log-ratio (ilr), and symmetry log-ratio (slr), combined with ordinary kriging (log-ratio kriging: alr_OK, clr_OK, ilr_OK and slr_OK) were selected to be compared with compositional kriging (CK) for the spatial prediction of soil psf in Tianlaochi of Heihe River Basin, China. Root mean squared error (RMSE), Aitchison's distance (AD), standardized residual sum of squares (STRESS) and right ratio of the predicted soil texture types (RR) were chosen to evaluate the accuracy for different interpolators. The results showed that CK had a better accuracy than the four log-ratio kriging methods. The RMSE (sand, 9.27%; silt, 7.67%; clay, 4.17%), AD (0.45), STRESS (0.60) of CK were the lowest and the RR (58.65%) was the highest in the five interpolators. The clr_OK achieved relatively better performance than the other log-ratio kriging methods. In addition, CK presented reasonable and smooth transition on mapping soil psf according to the environmental factors. The study gives insights for mapping soil psf accurately by comparing different methods for compositional data interpolation. Further researches of methods combined with ancillary variables are needed to be implemented to improve the interpolation performance.

[Spatial distribution prediction of surface soil Pb in a battery contaminated site].

Liu, Geng; Niu, Jun-Jie; Zhang, Chao; Zhao, Xin; Guo, Guan-Lin

2014-12-01

In order to enhance the reliability of risk estimation and to improve the accuracy of pollution scope determination in a battery contaminated site with the soil characteristic pollutant Pb, four spatial interpolation models, including Combination Prediction Model (OK(LG) + TIN), kriging model (OK(BC)), Inverse Distance Weighting model (IDW), and Spline model were employed to compare their effects on the spatial distribution and pollution assessment of soil Pb. The results showed that Pb concentration varied significantly and the data was severely skewed. The variation coefficient of the site was higher in the local region. OK(LG) + TIN was found to be more accurate than the other three models in predicting the actual pollution situations of the contaminated site. The prediction accuracy of other models was lower, due to the effect of the principle of different models and datum feature. The interpolation results of OK(BC), IDW and Spline could not reflect the detailed characteristics of seriously contaminated areas, and were not suitable for mapping and spatial distribution prediction of soil Pb in this site. This study gives great contributions and provides useful references for defining the remediation boundary and making remediation decision of contaminated sites.

Uptake of leptin and albumin via separate pathways in proximal tubule cells.

The adipokine leptin and oncotic protein albumin are endocytosed in the proximal tubule via the scavenger receptor megalin. Leptin reduces megalin expression and activates cell signalling pathways that upregulate fibrotic protein expression. The aim of this study was to investigate if leptin uptake in proximal tubule cells was via the albumin-megalin endocytic complex. In immortalised proximal tubule Opossum kidney cells (OK) fluorescent leptin and albumin co-localised following 5min exposure, however there was no co-localisation at 10, 20 and 30min exposure. In OK cells, acute exposure to leptin for 2h did not alter NHE3, ClC-5, NHERF1 and NHERF2 mRNA. However, acute leptin exposure increased NHERF2 protein expression in proximal tubule cells. In OK cells, immunoprecipitation experimentation indicated leptin did not bind to ClC-5. Leptin uptake in OK cells was enhanced by bafilomycin and ammonium chloride treatment, demonstrating that uptake was not dependent on lysosomal pH. Thus, it is likely that two pools of megalin exist in proximal tubule cells to facilitate separate uptake of leptin and albumin by endocytosis. Copyright © 2016 Elsevier Ltd. All rights reserved.

Geostatistical interpolation methods to estimate individual exposure to outdoor air pollutants can be used in pregnancy cohorts where personal exposure data are not collected. Our objectives were to a) develop four assessment methods (citywide average (CWA); nearest monitor (NM); inverse distance weighting (IDW); and ordinary Kriging (OK)), and b) compare daily metrics and cross-validations of interpolation models. We obtained 2008 hourly data from Mexico City's outdoor air monitoring network for PM10, PM2.5, O3, CO, NO2, and SO2 and constructed daily exposure metrics for 1,000 simulated individual locations across five populated geographic zones. Descriptive statistics from all methods were calculated for dry and wet seasons, and by zone. We also evaluated IDW and OK methods' ability to predict measured concentrations at monitors using cross validation and a coefficient of variation (COV). All methods were performed using SAS 9.3, except ordinary Kriging which was modeled using R's gstat package. Overall, mean concentrations and standard deviations were similar among the different methods for each pollutant. Correlations between methods were generally high (r=0.77 to 0.99). However, ranges of estimated concentrations determined by NM, IDW, and OK were wider than the ranges for CWA. Root mean square errors for OK were consistently equal to or lower than for the IDW method. OK standard errors varied considerably between pollutants and the computed COVs ranged from 0.46 (least error) for SO2 and PM10 to 3.91 (most error) for PM2.5. OK predicted concentrations measured at the monitors better than IDW and NM. Given the similarity in results for the exposure methods, OK is preferred because this method alone provides predicted standard errors which can be incorporated in statistical models. The daily estimated exposures calculated using these different exposure methods provide flexibility to evaluate multiple windows of exposure during pregnancy, not just trimester or pregnancy-long exposures. Many studies evaluating associations between outdoor air pollution and adverse pregnancy outcomes rely on outdoor air pollution monitoring data linked to information gathered from large birth registries, and often lack residence location information needed to estimate individual exposure. This study simulated 1,000 residential locations to evaluate four air pollution exposure assessment methods, and describes possible exposure misclassification from using spatial averaging versus geostatistical interpolation models. An implication of this work is that policies to reduce air pollution and exposure among pregnant women based on epidemiologic literature should take into account possible error in estimates of effect when spatial averages alone are evaluated.

2007-05-01

Mercuric chloride (HgCl(2)) is a highly toxic compound, which can cause nephrotoxic damage. In the present study effects of HgCl(2) on mitochondria integrity and energy metabolism, as well as antidotal effects of 2,3-dimercaptopropane-1-sulfonate (DMPS) were investigated in the opossum kidney derived cell line (OK). OK cell monolayers were incubated during 0, 1, 3, 6, and 9 h in serum-free culture medium containing 15 microM HgCl(2), either in the absence or in the presence of 60 microM DMPS in a 1:4 ratio. Intracellular ATP content, MTT reduction, and HSP70/HSP90 induction were studied; confocal, transmission electron microscopy, and light microscopy studies were also performed. For confocal analysis, a mitochondrial selective probe (MitoTracker Red CMXH2Ros) was used. Antioxidant activity of DMPS was also studied by the scavenging of the free radical 2, 2-diphenyl-1-picrylhydrazyl (DPPH) technique. A decrease of ATP content, an impaired ability to reduce tetrazolium, and dramatic changes on cellular and mitochondrial morphology, and energetic levels were found after either 6 or 9 h of HgCl(2) exposure. Increased expression of HSP90 and HSP70 were also seen. When OK cells were co-incubated with HgCl(2) and DMPS, cellular morphology, viability, intracellular ATP, and mitochondrial membrane potential were partially restored; a protective effect on mitochondrial morphology was also seen. DMPS also showed potent antioxidant activity in vitro. Mitochondrial protection could be the cellular mechanism mediated by DMPS in OK cells exposed to a toxic concentration of HgCl(2).

2017-02-14

Moso bamboo (Phyllostachys heterocycla (Carr.) Mitford cv. Pubescens) is an important timber substitute in China. Site specific stand management requires an accurate estimate of soil organic carbon (SOC) stock for maintaining stand productivity and understanding global carbon cycling. This study compared ordinary kriging (OK) and inverse distance weighting (IDW) approaches to study the spatial distribution of SOC stock within 0-60 cm using 111 soil samples in Moso bamboo forests in subtropical China. Similar spatial patterns but different spatial distribution ranges of SOC stock from OK and IDW highlighted the necessity to apply different approaches to obtain accurate and consistent results of SOC stock distribution. Different spatial patterns of SOC stock suggested the use of different fertilization treatments in Moso bamboo forests across the study area. SOC pool within 0-60 cm was 6.46 and 6.22 Tg for OK and IDW; results which were lower than that of conventional approach (CA, 7.41 Tg). CA is not recommended unless coordinates of the sampling locations are missing and the spatial patterns of SOC stock are not required. OK is recommended for the uneven distribution of sampling locations. Our results can improve methodology selection for investigating spatial distribution of SOC stock in Moso bamboo forests.

Update on Heavy-Meson Spectrum Tests of the Oktay--Kronfeld Action

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bailey, Jon A.; Jang, Yong-Chull; Lee, Weonjong

2016-01-18

We present updated results of a numerical improvement test with heavy-meson spectrum for the Oktay--Kronfeld (OK) action. The OK action is an extension of the Fermilab improvement program for massive Wilson fermions including all dimension-six and some dimension-seven bilinear terms. Improvement terms are truncated by HQET power counting atmore » $$\\mathrm{O}(\\Lambda^3/m_Q^3)$$ for heavy-light systems, and by NRQCD power counting at $$\\mathrm{O}(v^6)$$ for quarkonium. They suffice for tree-level matching to QCD to the given order in the power-counting schemes. To assess the improvement, we generate new data with the OK and Fermilab action that covers both charm and bottom quark mass regions on a MILC coarse $$(a \\approx 0.12~\\text{fm})$$ $2+1$ flavor, asqtad-staggered ensemble. We update the analyses of the inconsistency quantity and the hyperfine splittings for the rest and kinetic masses. With one exception, the results clearly show that the OK action significantly reduces heavy-quark discretization effects in the meson spectrum. The exception is the hyperfine splitting of the heavy-light system near the $$B_s$$ meson mass, where statistics are too low to draw a firm conclusion, despite promising results.« less

To determine the diagnostic accuracy of spot urine creatinine concentration (UCC) as a new test for the evaluation of differential renal function in obstructed kidneys (DRF(ok)) drained by percutaneous nephrostomy tube (PCNT). In patients with obstructed kidneys drained by PCNT, DRF(ok) was derived from UCC by comparing the value of UCC in the obstructed kidney to the value in the contralateral kidney, and was derived from dimercaptosuccinic acid (DMSA) renal scans and creatinine clearance (CCr) using standard methods. Subsequently, the results of UCC were compared to the results of DMSA and CCr. 61 patients were enrolled. Bland-Altman plots to compare DMSA and UCC showed that the upper limit of agreement was 14.8% (95% CI 10.7-18.5) and the lower limit was -19.9% (95% CI -23.8 to -16.1). The sensitivity and specificity of detecting DMSA DRF(ok) < or = 35% using UCC was 85.2 and 91.2%, respectively. When UCC was compared to CCr, Bland-Altman tests gave an upper limit of agreement of 10.4% (95% CI 7.9-12.8) and a lower limit of agreement of -11.3% (95% CI -13.8 to -8.9). UCC is accurate in the estimation of DRF(ok) drained by PCNT. 2008 S. Karger AG, Basel

Protein Polymerization into Fibrils from the Viewpoint of Nucleation Theory.

PubMed

Kashchiev, Dimo

2015-11-17

The assembly of various proteins into fibrillar aggregates is an important phenomenon with wide implications ranging from human disease to nanoscience. Using general kinetic results of nucleation theory, we analyze the polymerization of protein into linear or helical fibrils in the framework of the Oosawa-Kasai (OK) model. We show that while within the original OK model of linear polymerization the process does not involve nucleation, within a modified OK model it is nucleation-mediated. Expressions are derived for the size of the fibril nucleus, the work for fibril formation, the nucleation barrier, the equilibrium and stationary fibril size distributions, and the stationary fibril nucleation rate. Under otherwise equal conditions, this rate decreases considerably when the short (subnucleus) fibrils lose monomers much more frequently than the long (supernucleus) fibrils, a feature that should be born in mind when designing a strategy for stymying or stimulating fibril nucleation. The obtained dependence of the nucleation rate on the concentration of monomeric protein is convenient for experimental verification and for use in rate equations accounting for nucleation-mediated fibril formation. The analysis and the results obtained for linear fibrils are fully applicable to helical fibrils whose formation is describable by a simplified OK model. Copyright © 2015 Biophysical Society.

We present heavy-meson spectrum results obtained using the Oktay--Kronfeld (OK) action on MILC asqtad lattices. The OK action was designed to improve the heavy-quark action of the Fermilab formulation, such that heavy-quark discretization errors are reduced. The OK action includes dimension-6 and -7 operators necessary for tree-level matching to QCD through ordermore » $$\\mathrm{O}(\\Lambda^3/m_Q^3)$$ for heavy-light mesons and $$\\mathrm{O}(v^6)$$ for quarkonium, or, equivalently, through $$\\mathrm{O}(a^2)$$ with some $$\\mathrm{O}(a^3)$$ terms with Symanzik power counting. To assess the improvement, we extend previous numerical tests with heavy-meson masses by analyzing data generated on a finer ($$a \\approx 0.12\\;$$fm) lattice with the correct tadpole factors for the $$c_5$$ term in the action.

Fibrinogen residue B{beta}432Asp is part of hole 'b' that interacts with knob 'B,' whose sequence starts with Gly-His-Arg-Pro-amide (GHRP). Because previous studies showed B{beta}D432A has normal polymerization, we hypothesized that B{beta}432Asp is not critical for knob 'B' binding and that new knob-hole interactions would compensate for the loss of this Asp residue. To test this hypothesis, we solved the crystal structure of fragment D from B{beta}D432A. Surprisingly, the structure (rfD-B{beta}D432A+GH) showed the peptide GHRP was not bound to hole 'b.' We then re-evaluated the polymerization of this variant by examining clot turbidity, clot structure, and the rate of FXIIIa cross-linking.more » The turbidity and the rate of - dimer formation for B{beta}D432A were indistinguishable compared with normal fibrinogen. Scanning electron microscopy showed no significant differences between the clots of B{beta}D432A and normal, but the thrombin-derived clots had thicker fibers than clots obtained from batroxobin, suggesting that cleavage of FpB is more important than 'B:b' interactions. We conclude that hole 'b' and 'B:b' knob-hole binding per se have no influence on fibrin polymerization.« less

The Oktay-Kronfeld (OK) action extends the Fermilab improvement program for massive Wilson fermions to higher order in suitable power-counting schemes. It includes dimension-six and -seven operators necessary for matching to QCD through ordermore » $${\\mathrm{O}}(\\Lambda^3/m_Q^3)$$ in HQET power counting, for applications to heavy-light systems, and $${\\mathrm{O}}(v^6)$$ in NRQCD power counting, for applications to quarkonia. In the Symanzik power counting of lattice gauge theory near the continuum limit, the OK action includes all $${\\mathrm{O}}(a^2)$$ and some $${\\mathrm{O}}(a^3)$$ terms. To assess whether the theoretical improvement is realized in practice, we study combinations of heavy-strange and quarkonia masses and mass splittings, designed to isolate heavy-quark discretization effects. We find that, with one exception, the results obtained with the tree-level-matched OK action are significantly closer to the continuum limit than the results obtained with the Fermilab action. The exception is the hyperfine splitting of the bottom-strange system, for which our statistical errors are too large to draw a firm conclusion. Lastly, these studies are carried out with data generated with the tadpole-improved Fermilab and OK actions on 500 gauge configurations from one of MILC's $$a\\approx0.12$$~fm, $$N_f=2+1$$-flavor, asqtad-staggered ensembles.« less

In this study, we investigated the anti-obesity effects of kimchi (Korean traditional fermented vegetable) fermented either without starter culture or with a specific starter culture, Weissella koreensis OK1-6. C57BL/6J mice were divided into four groups (n = 7); normal diet, HF (high-fat diet), HF-KC (high-fat diet containing 3% kimchi manufactured without starter) and HF-KCO (high-fat diet containing 3% kimchi manufactured with the starter culture W. koreensis OK1-6). After 12 weeks of dietary intervention, the mice were killed, and serum and tissue samples were examined. Serum and hepatic lipid profile, insulin, leptin concentration and expression level of lipid anabolic genes like peroxisome proliferator-activated receptor γ, stearoyl-CoA desaturase-1, liver X receptor α and SREBP2 were significantly decreased (<0.05) along with body and epididymal fat pad weight in the HF-KCO group compared with the HF-KC and HF group. These results suggested that kimchi fermented with the starter W. koreensis OK1-6 has anti-obesity effects in HF-induced obese mice. These results may contribute to nutraceutical and food industries in developing functional food and probiotics based therapies for the treatment and prevention of obesity. © 2012 The Society for Applied Microbiology.

In this study, a radial basis function neural network model combined with ordinary kriging (RBFNN_OK) was adopted to predict the spatial distribution of soil nutrients (organic matter and total N) in a typical hilly region of Sichuan Basin, Southwest China, and the performance of this method was compared with that of ordinary kriging (OK) and regression kriging (RK). All the three methods produced the similar soil nutrient maps. However, as compared with those obtained by multiple linear regression model, the correlation coefficients between the measured values and the predicted values of soil organic matter and total N obtained by neural network model increased by 12. 3% and 16. 5% , respectively, suggesting that neural network model could more accurately capture the complicated relationships between soil nutrients and quantitative environmental factors. The error analyses of the prediction values of 469 validation points indicated that the mean absolute error (MAE) , mean relative error (MRE), and root mean squared error (RMSE) of RBFNN_OK were 6.9%, 7.4%, and 5. 1% (for soil organic matter), and 4.9%, 6.1% , and 4.6% (for soil total N) smaller than those of OK (P<0.01), and 2.4%, 2.6% , and 1.8% (for soil organic matter), and 2.1%, 2.8%, and 2.2% (for soil total N) smaller than those of RK, respectively (P<0.05).

We investigated socioeconomic differences in patient-reported outcomes after a hip or knee replacement and the contribution of health differences beforehand. Our sample included 121 983 patients in England who had an operation in 2009-2011. Socioeconomic status was measured with quintiles of the ranking of areas by the English Index of Multiple Deprivation. Outcomes at 6 months were the Oxford hip or knee score (OHS or OKS) that measure pain and disability on a scale from 0 (worst) to 48 (best), and the percentage reporting no improvement in problems. Adjustment was made for age, sex, ethnicity, comorbidity, general health, revision surgery, primary diagnosis, preoperative OHS or OKS and having longstanding problems. Comparing the most- with the least-deprived group, the mean OHS was 5.0 points lower and the OKS 5.4 lower. Adjusted differences, reflecting the differences in improvement in the condition, were 2.8 [95% confidence interval (CI): 2.5-3.0] on OHS and 2.4 (95% CI: 2.2-2.7) on OKS. Adjusted odds ratios for reporting no improvement were 1.4 (1.2-1.6) for the hip and 1.4 (1.3-1.5) for the knee. On average, patients living in socioeconomically deprived areas had worse outcomes after surgery, partly related to preoperative differences in health and disease severity and partly to less postoperative improvement.

Pedal peptide/orcokinin-type neuropeptide signaling in a deuterostome: The anatomy and pharmacology of starfish myorelaxant peptide in Asterias rubens.

PubMed

Lin, Ming; Egertová, Michaela; Zampronio, Cleidiane G; Jones, Alexandra M; Elphick, Maurice R

2017-12-15

Pedal peptide (PP) and orcokinin (OK) are related neuropeptides that were discovered in protostomian invertebrates (mollusks, arthropods). However, analysis of genome/transcriptome sequence data has revealed that PP/OK-type neuropeptides also occur in a deuterostomian phylum-the echinoderms. Furthermore, a PP/OK-type neuropeptide (starfish myorelaxant peptide, SMP) was recently identified as a muscle relaxant in the starfish Patiria pectinifera. Here mass spectrometry was used to identify five neuropeptides (ArPPLN1a-e) derived from the SMP precursor (PP-like neuropeptide precursor 1; ArPPLNP1) in the starfish Asterias rubens. Analysis of the expression of ArPPLNP1 and neuropeptides derived from this precursor in A. rubens using mRNA in situ hybridization and immunohistochemistry revealed a widespread pattern of expression, with labeled cells and/or processes present in the radial nerve cords, circumoral nerve ring, digestive system (e.g., cardiac stomach) and body wall-associated muscles (e.g., apical muscle) and appendages (e.g., tube feet and papulae). Furthermore, our data provide the first evidence that neuropeptides are present in the lateral motor nerves and in nerve processes innervating interossicular muscles. In vitro pharmacological tests with SMP (ArPPLN1b) revealed that it causes dose-dependent relaxation of apical muscle, tube foot and cardiac stomach preparations from A. rubens. Collectively, these anatomical and pharmacological data indicate that neuropeptides derived from ArPPLNP1 act as inhibitory neuromuscular transmitters in starfish, which contrasts with the myoexcitatory actions of PP/OK-type neuropeptides in protostomian invertebrates. Thus, the divergence of deuterostomes and protostomes may have been accompanied by an inhibitory-excitatory transition in the roles of PP/OK-type neuropeptides as regulators of muscle activity. © 2017 The Authors The Journal of Comparative Neurology Published by Wiley Periodicals, Inc.

[Influence of cations on the laser Raman spectra of silicate glasses].

PubMed

Xiong, Yi; Zhao, Hong-xia; Gan, Fu-xi

2012-04-01

Na2O(K2O)-CaO(MgO)-SiO2, Na2O(K2O)-Al2O3-SiO2, Na2O(K2O)-B2O3-SiO2, Na2O(K2O)-PbO-SiO2 and PbO-BaO-SiO2 glass systems were investigated using laser Raman spectroscopic technique. The modification of short-range structure of glass caused by network modifier cations will influence Raman signature. Alkali and alkali-earth ions can weaken the bridging oxygen bond, thus lower the frequency of Si-O(b)-Si anti-symmetric stretching vibration. When coordina ted by oxygen ions, B3+ can form [BO4] tetrahedron and enter the silicon-oxygen network, but this effect had little impact on the frequency of Raman peaks located in the high-frequency region. Al3+ can also be coordinated by oxygen ions to form [AlO4] tetrahedron. [AlO4] will increase the disorder degree of network while entering network. Ba2+ can increase the density of electron cloud along the Si-O(nb) bond when it bonds with non-bridging oxygen, which will lead to a higher peak intensity of O-Si-O stretching vibration. The Raman peaks of alkli- and alkali-earth silicate glasses are mainly distributed in the region of 400 - 1 200 cm(-1), while in the spectrum of Na2O(K2O)-PbO-SiO2 glass system a 131 cm(-1) peak existed. The authors assigned it to the Pb-O symmetric stretching vibration. Some of the samples were produced in the laboratory according to the average compositions of ancient glasses, so this research is very significant to discriminating ancient silicate glasses of different systems by Laser Raman spectroscopic technique.

Oviposition Deterrence Induced by Ocimum kilimandscharicum and Ocimum suave Extracts to Gravid Anopheles gambiae s.s (Diptera: Culicidae) in Laboratory

Background: In most of the past decades, mosquito control has been done by the use of indoor residual spray and insecticides-treated bed nets. The control of mosquitoes by targeting the breeding sites (larval habitat) has not been given priority. Disrupting the oviposition sensory detection of mosquitoes by introducing deterrents of plant origin, which are cheap resources, might be add value to integrated vector control. Such knowledge is required in order to successfully manipulate the behavior of mosquitoes for monitoring or control. Materials and Methods: Twenty gravid mosquitoes were placed in a cage measuring 30 × 30 × 30 cm for oviposition. The oviposition media were made of different materials. Experiments were set up at 6:00 pm, and eggs were collected for counting at 7:30 am. Mosquitoes were observed until they died. The comparisons of the number of eggs were made between the different treatments. Results: There was significant difference in the number of eggs found in control cups when compared with the number of eggs found in water treated with Ocimum kilimandscharicum (OK) (P=0.02) or Ocimum suave (OS) (P=0.000) and that found in water with debris treated with OK (P=0.011) or OS (P=0.002). There was no significant difference in the number of eggs laid in treated water and the number of eggs laid in water with debris treated either with OK (P=0.105) or OS (P=0.176). Oviposition activity index for both OS and OK experiments lay in a negative side and ranged from -0.19% to -1%. The results show that OS and OK deter oviposition in An.gambiae s.s. Conclusions: Further research needs to be done on the effect of secondary metabolites of these plant extracts as they decompose in the breeding sites. In the event of favorable results, the potential of these plant extracts can be harnessed on a larger scale. PMID:20927285

Linear nevus sebaceous syndrome (LNSS) is a rare neurocutaneous syndrome, characterized by nevus sebaceous,central nervous system (CNS), ocular and skeletal abnormalities. The present study describes KRAS somatic mosaic mutation in a case of LNSS with lymphatic malformations (LMs). A 4-month-old female with a clinical diagnosis of LNSS presented with infantile spasms, mental retardation, skull dysplasia, ocular abnormalities, congenital atrial septal defect, and LMs. Cervical ultrasonography revealed a 4.6 × 4.6 × 2.2cm no echo packet with clear boundary in the subcutaneous tissues of the right neck. The neck MRI indicated a cyst in the subcutaneous tissues of the right neck. Whole-exome sequencing revealed a low-level heterozygous mutation of the KRAS gene (c.35C > T; p.G12D, 19%) in the skin lesion sample. This mutation was not present in the blood samples of the patient and her parents. The patient received sclerotherapy with paicibanil (OK-432) injection for the cyst. Following 1 year of treatment, the patient exhibited fewer seizures. The mental and motor development was significantly improved. The patient can currently walk with assistance and speak simple words. LNSS is a rare, congenital neurocutaneous syndrome consisting of a spectrum of abnormalities involving the skin, central nervous system, eyes, LMs and other systems. LNSS can be caused by postzygotic somatic mutation in the RAS family of genes. Multidisciplinary evaluation and treatment is needed. Copyright © 2017 The Authors.

Relative elevation and stream power index were selected as auxiliary variables based on correlation analysis for mapping soil organic matter. Geographically weighted regression Kriging (GWRK) and regression Kriging (RK) were used for spatial interpolation of soil organic matter and compared with ordinary Kriging (OK), which acts as a control. The results indicated that soil or- ganic matter was significantly positively correlated with relative elevation whilst it had a significantly negative correlation with stream power index. Semivariance analysis showed that both soil organic matter content and its residuals (including ordinary least square regression residual and GWR resi- dual) had strong spatial autocorrelation. Interpolation accuracies by different methods were esti- mated based on a data set of 98 validation samples. Results showed that the mean error (ME), mean absolute error (MAE) and root mean square error (RMSE) of RK were respectively 39.2%, 17.7% and 20.6% lower than the corresponding values of OK, with a relative-improvement (RI) of 20.63. GWRK showed a similar tendency, having its ME, MAE and RMSE to be respectively 60.6%, 23.7% and 27.6% lower than those of OK, with a RI of 59.79. Therefore, both RK and GWRK significantly improved the accuracy of OK interpolation of soil organic matter due to their in- corporation of auxiliary variables. In addition, GWRK performed obviously better than RK did in this study, and its improved performance should be attributed to the consideration of sample spatial locations.

There is conflicting evidence about the merits of mobile bearings in total knee replacement, partly because most randomised controlled trials (RCTs) have not been adequately powered. We report the results of a multicentre RCT of mobile versus fixed bearings. This was part of the knee arthroplasty trial (KAT), where 539 patients were randomly allocated to mobile or fixed bearings and analysed on an intention-to-treat basis. The primary outcome measure was the Oxford Knee Score (OKS) plus secondary measures including Short Form-12, EuroQol EQ-5D, costs, cost-effectiveness and need for further surgery. There was no significant difference between the groups pre-operatively: mean OKS was 17.18 (sd 7.60) in the mobile-bearing group and 16.49 (sd 7.40) in the fixed-bearing group. At five years mean OKS was 33.19 (sd 16.68) and 33.65 (sd 9.68), respectively. There was no significant difference between trial groups in OKS at five years (-1.12 (95% confidence interval -2.77 to 0.52) or any of the other outcome measures. Furthermore, there was no significant difference in the proportion of patients with knee-related re-operations or in total costs. In this appropriately powered RCT, over the first five years after total knee replacement functional outcomes, re-operation rates and healthcare costs appear to be the same irrespective of whether a mobile or fixed bearing is used.

Applying spatial analysis techniques to assess the suitability of multipurpose uses of spring water in the Jiaosi Hot Spring Region, Taiwan.

The Jiaosi Hot Spring Region is one of the most famous tourism destinations in Taiwan. The spring water is processed for various uses, including irrigation, aquaculture, swimming, bathing, foot spas, and recreational tourism. Moreover, the multipurpose uses of spring water can be dictated by the temperature of the water. To evaluate the suitability of spring water for these various uses, this study spatially characterized the spring water temperatures of the Jiaosi Hot Spring Region by integrating ordinary kriging (OK), sequential Gaussian simulation (SGS), and Geographic information system (GIS). First, variogram analyses were used to determine the spatial variability of spring water temperatures. Next, OK and SGS were adopted to model the spatial uncertainty and distributions of the spring water temperatures. Finally, the land use (i.e., agriculture, dwelling, public land, and recreation) was determined using GIS and combined with the estimated distributions of the spring water temperatures. A suitable development strategy for the multipurpose uses of spring water is proposed according to the integration of the land use and spring water temperatures. The study results indicate that the integration of OK, SGS, and GIS is capable of characterizing spring water temperatures and the suitability of multipurpose uses of spring water. SGS realizations are more robust than OK estimates for characterizing spring water temperatures compared to observed data. Furthermore, current land use is almost ideal in the Jiaosi Hot Spring Region according to the estimated spatial pattern of spring water temperatures.

Microbial diarrheal diseases are one of the leading causes of child morbidity and mortality in developing countries. This study aimed to identify the main causes of non-bacterial diarrhea in Afghanistan. A total of 699 stools were collected from children aged under 5 years who presented with diarrhea at Indira Gandhi and Kandahar hospitals. Frozen aliquots were preserved for screening against rotavirus, astrovirus, adenovirus, norovirus, Cryptosporidium and Giardia, when bacterial cultures tested negative. Tests were performed at the hospitals after laboratory staff were trained and provided with enzyme-immunoassays and equipment. Results were confirmed at the U.S. Naval Medical Research Unit No. 3, Cairo, Egypt. Of the samples tested, 71.9% (503/699) were infected with one or more pathogens. However, the majority (85.8%; 432/503) showed single infections: rotavirus (72.2%; 329/432), Cryptosporidium (14.1%; 61/432), Giardia (5.1%; 22/432), astrovirus (2.3%; 10/432), adenovirus (1.6%; 7/432) and norovirus (0.7%; 3/432). The remaining 14% (71/503) showed mixed infections of the tested pathogens. Non-bacterial pathogens were identified that could enable health officials to adopt more effective treatment and control measures for diarrhea in Afghanistan.

Repeated Measurement of Absolute and Relative Judgments of Loudness: Clinical Relevance for Prescriptive Fitting of Aided Target Gains for soft, Comfortable, and Loud, But Ok Sound Levels.

This study was undertaken with the purpose of streamlining clinical measures of loudness growth to facilitate and enhance prescriptive fitting of nonlinear hearing aids. Repeated measures of loudness at 500 and 3,000 Hz were obtained bilaterally at monthly intervals over a 6-month period from three groups of young adult listeners. All volunteers had normal audiometric hearing sensitivity and middle ear function, and all denied problems related to sound tolerance. Group 1 performed judgments of soft and loud, but OK for presentation of ascending sound levels. We defined these judgments operationally as absolute judgments of loudness. Group 2 initially performed loudness judgments across a continuum of seven loudness categories ranging from judgments of very soft to uncomfortably loud for presentation of ascending sound levels per the Contour Test of Loudness; we defined these judgments as relative judgments of loudness. In the same session, they then performed the absolute judgments for soft and loud, but OK sound levels. Group 3 performed the same set of loudness judgments as did group 2, but the task order was reversed such that they performed the absolute judgments initially within each test session followed by the relative judgments. The key findings from this study were as follows: (1) Within group, the absolute and relative tasks yielded clinically similar judgments for soft and for loud, but OK sound levels. These judgments were largely independent of task order, ear, frequency, or trial order within a given session. (2) Loudness judgments increased, on average, by ∼3 dB between the first and last test session, which is consistent with the commonly reported acclimatization effect reported for incremental changes in loudness discomfort levels as a consequence of chronic bilateral hearing aid use. (3) Measured and predicted comfortable judgments of loudness were in good agreement for the individual listener and for groups of listeners. These comfortable judgments bisect the measured levels judged for soft and for loud, but OK sounds. (4) Loudness judgments within the same loudness category varied across listeners within group by as much as 50 to 60 dB. Such large variation in judgments of loudness is problematic, especially because hearing-impaired listeners are known to exhibit similarly large ranges of intersubject response variation and, yet, poplar prescriptive fitting strategies continue to use average rather than individual loudness data to fit nonlinear hearing aids. The primary conclusions drawn from these findings are that reliable absolute judgments of soft and loud, but OK are clinically practical and economical to measure and, from these judgments, good estimates of comfortable loudness can also be predicted for individuals or for groups of listeners. Such loudness data, as measured as described in this report, offer promise for streamlining and enhancing prescriptive fitting of nonlinear hearing aids to target gain settings for soft (audible), comfortable , and loud, but OK (tolerable) sound inputs for the individual listener.

Hydrogen Sulfide Emissions from Sow Farm Lagoons across Climates Zones.

PubMed

Grant, Richard H; Boehm, Matthew T; Lawrence, Alfred J; Heber, Albert J

2013-11-01

Hydrogen sulfide (HS) emissions were measured periodically over the course of 2 yr at three sow waste lagoons representing humid mesothermal (North Carolina, NC), humid microthermal (Indiana, IN), and semiarid (Oklahoma, OK) climates. Emissions were determined using a backward Lagrangian stochastic model in conjunction with line-sampled HS concentrations and measured turbulence. The median annual sow-specific (area-specific) lagoon emissions at the OK farm were approximately 1.6 g head [hd] d (5880 µg m s), whereas those at the IN and NC sow farms were 0.035 g hd d (130 µg m s), and 0.041 g hd d (260 µg m s), respectively. Hydrogen sulfide emissions generally increased with wind speed. The daily HS emissions from the OK lagoon were greatest during the first half of the year and decreased as the year progressed. Emissions were episodic at the NC and IN lagoons. The generally low emissions at the NC and IN lagoons were probably a result of significant populations of purple sulfur bacteria maintained in the humid mesothermal and humid microthermal climates. Most of the large HS emission events at the NC and IN lagoons appeared to be a result of either precipitation events or liquid pump-out events. The high emissions at the OK lagoon in a semiarid climate were largely a result of high wind speeds enhancing both lagoon and air boundary layer mixing. The climate (air temperature, winds, and precipitation) appeared to influence the HS emissions from lagoons.

Does circumpatellar electrocautery improve the outcome after total knee replacement?: a prospective, randomised, blinded controlled trial.

PubMed

2012-09-01

The incidence of anterior knee pain following total knee replacement (TKR) is reported to be as high as 49%. The source of the pain is poorly understood but the soft tissues around the patella have been implicated. In theory circumferential electrocautery denervates the patella thereby reducing efferent pain signals. However, there is mixed evidence that this practice translates into improved outcomes. We aimed to investigate the clinical effect of intra-operative circumpatellar electrocautery in patients undergoing TKR using the LCS mobile bearing or Kinemax fixed bearing TKR. A total of 200 patients were randomised to receive either circumpatellar electrocautery (diathermy) or not (control). Patients were assessed by visual analogue scale (VAS) for anterior knee pain and Oxford knee score (OKS) pre-operatively and three months, six months and one year post-operatively. Patients and assessors were blinded. There were 91 patients in the diathermy group and 94 in the control. The mean VAS improvement at one year was 3.9 in both groups (control; -10 to 6, diathermy; -9 to 8, p < 0.001 in both cases, paired, two-tailed t-test). There was no significant difference in VAS between the groups at any other time. The mean OKS improvement was 17.7 points (0 to 34) in the intervention group and 16.6 (0 to 42) points in the control (p = 0.36). There was no significant difference between the two groups in OKS at any other time. We found no relevant effect of patellar electrocautery on either VAS anterior knee pain or OKS for patients undergoing LCS and Kinemax TKR.

Spatial interpolation methods and geostatistics for mapping groundwater contamination in a coastal area.

2017-04-01

Mapping groundwater contaminants and identifying the sources are the initial steps in pollution control and mitigation. Due to the availability of different mapping methods and the large number of emerging pollutants, these methods need to be used together in decision making. The present study aims to map the contaminated areas in Richards Bay, South Africa and compare the results of ordinary kriging (OK) and inverse distance weighted (IDW) interpolation techniques. Statistical methods were also used for identifying contamination sources. Na-Cl groundwater type was dominant followed by Ca-Mg-Cl. Data analysis indicate that silicate weathering, ion exchange and fresh water-seawater mixing are the major geochemical processes controlling the presence of major ions in groundwater. Factor analysis also helped to confirm the results. Overlay analysis by OK and IDW gave different results. Areas where groundwater was unsuitable as a drinking source were 419 and 116 km 2 for OK and IDW, respectively. Such diverse results make decision making difficult, if only one method was to be used. Three highly contaminated zones within the study area were more accurately identified by OK. If large areas are identified as being contaminated such as by IDW in this study, the mitigation measures will be expensive. If these areas were underestimated, then even though management measures are taken, it will not be effective for a longer time. Use of multiple techniques like this study will help to avoid taking harsh decisions. Overall, the groundwater quality in this area was poor, and it is essential to identify alternate drinking water source or treat the groundwater before ingestion.

Heterologous expression of pyrroloquinoline quinone (pqq) gene cluster confers mineral phosphate solubilization ability to Herbaspirillum seropedicae Z67.

Gluconic acid secretion mediated by the direct oxidation of glucose by pyrroloquinoline quinone (PQQ)-dependent glucose dehydrogenase (GDH) is responsible for mineral phosphate solubilization in Gram-negative bacteria. Herbaspirillum seropedicae Z67 (ATCC 35892) genome encodes GDH apoprotein but lacks genes for the biosynthesis of its cofactor PQQ. In this study, pqqE of Erwinia herbicola (in plasmid pJNK1) and pqq gene clusters of Pseudomonas fluorescens B16 (pOK53) and Acinetobacter calcoaceticus (pSS2) were over-expressed in H. seropedicae Z67. Transformants Hs (pSS2) and Hs (pOK53) secreted micromolar levels of PQQ and attained high GDH activity leading to secretion of 33.46 mM gluconic acid when grown on 50 mM glucose while Hs (pJNK1) was ineffective. Hs (pJNK1) failed to solubilize rock phosphate, while Hs (pSS2) and Hs (pOK53) liberated 125.47 μM and 168.07 μM P, respectively, in minimal medium containing 50 mM glucose under aerobic conditions. Moreover, under N-free minimal medium, Hs (pSS2) and Hs (pOK53) not only released significant P but also showed enhanced growth, biofilm formation, and exopolysaccharide (EPS) secretion. However, indole acetic acid (IAA) production was suppressed. Thus, the addition of the pqq gene cluster, but not pqqE alone, is sufficient for engineering phosphate solubilization in H. seropedicae Z67 without compromising growth under nitrogen-fixing conditions.

The purpose of this study was to conduct a meta-analysis comparing rigid gas permeable lenses (RGP) with soft contact lenses (SCL), spectacles and orthokeratology (OK) lenses for myopia control with respect to axial length elongation, spherical equivalent and measures of corneal curvature. Medline, Cochrane, EMBASE, and Google Scholar databases were searched to September 29, 2015 using the following keywords: rigid gas permeable contact lens; refractive error; and refractive abnormalities. Randomized controlled trials, two-arm prospective studies and retrospective studies of children with myopia treated with RGP lenses compared with spectacles, SCL, and OK lenses were included. Outcome measures were changes of axial length, spherical equivalent, flatter meridian, steeper meridian and corneal apical radius. Five studies were included. Three studies reported axial length change after 2-3 years of treatment with RGP lenses and SCL/spectacles and no difference between the groups was noted (pooled mean difference = -0.077, 95% confidence interval [CI]: -0.120 to 0.097, p = 0.840). Two studies reported a change of spherical equivalent after 2-3 years of treatment with RGP lenses and SCL/spectacles, and no difference between the groups was noted (pooled mean difference = 0.275, 95% CI: -0.390 to 0.941, p = 0.417). Two studies compared corneal curvature measures between RGP and OK lenses after 3-6 months of treatment and no differences in any measures of corneal curvature were seen. The effect of RGP lenses and SCL/spectacles on axial length elongation and spherical equivalent and of RGP and OK lenses on corneal curvature in children with myopia was similar.

Our previous work on wind power curve modeling using statistical models focused on a location with a moderately complex terrain in the Altamont Pass region in northern California (CA). The work described here is the follow-up to that work, but at a location with a simple terrain in northern Oklahoma (OK). The goal of the present analysis was to determine the gain in predictive ability afforded by adding information beyond the hub-height wind speed, such as wind speeds at other heights, as well as other atmospheric variables, to the power prediction model at this new location and compare the resultsmore » to those obtained at the CA site in the previous study. While we reach some of the same conclusions at both sites, many results reported for the CA site do not hold at the OK site. In particular, using the entire vertical profile of wind speeds improves the accuracy of wind power prediction relative to using the hub-height wind speed alone at both sites. However, in contrast to the CA site, the rotor equivalent wind speed (REWS) performs almost as well as the entire profile at the OK site. Another difference is that at the CA site, adding wind veer as a predictor significantly improved the power prediction accuracy. The same was true for that site when air density was added to the model separately instead of using the standard air density adjustment. At the OK site, these additional variables result in no significant benefit for the prediction accuracy.« less

The relationship between engagement in outpatient treatment facilities in the public sector and subsequent arrest is examined for clients in Connecticut, New York, Oklahoma and Washington. Engagement is defined as receiving another treatment service within 14 days of beginning a new episode of specialty treatment and at least two additional services within the next 30 days. Data are from 2008 and survival analysis modeling is used. Survival analyses express the effects of model covariates in terms of “hazard ratios,” which reflect a change in the likelihood of outcome because of the covariate. Engaged clients had a significantly lower hazard of any arrest than non-engaged in all four states. In NY and OK, engaged clients also had a lower hazard of arrest for substance-related crimes. In CT, NY, and OK engaged clients had a lower hazard of arrest for violent crime. Clients in facilities with higher engagement rates had a lower hazard of any arrest in NY and OK. Engaging clients in outpatient treatment is a promising approach to decrease their subsequent criminal justice involvement. PMID:24238717

Novel nickel-titanium rotary files with proprietary manufacturing techniques have recently been marketed. The purpose of this study was to assess multiple autoclave cycle effects on cyclic fatigue of GT Series X files (Dentsply Tulsa Dental Specialties, Tulsa, OK) and Twisted Files (SybronEndo, Orange, CA) METHODS: A jig using a 5-mm radius curve with 90° of maximum file flexure was used to induce cyclic fatigue failure. Files (n = 10) representing each experimental group (GT Series X 20/.04 and 20/.06; Twisted Files 25/.04 and 25/.06) were first tested to establish baseline mean cycles to failure (MCF). Experimental groups (n = 20) were then cycled to 25% of the established baseline MCF and then autoclaved. Additional autoclaving was accomplished at 50% and 75% of MCF followed by continual testing until failure. Control groups (n = 20) underwent the same procedures except autoclaving was not accomplished. The GT Series X (20/.04 and 20/.06) files showed no significant difference (p = 0.918/p = 0.096) in MCF for experimental versus control files. Twisted Files (25/.04) showed no significant difference (p = 0.432) in MCF between experimental and control groups. However, the Twisted Files (25/.06) experimental group showed a significantly lower (p = 0.0175) MCF compared with the controls. Under the conditions of this evaluation, autoclave sterilization significantly decreased cyclic fatigue resistance of one of the four file groups tested. Repeated autoclaving significantly reduced the MCF of 25/.06 Twisted Files; however, 25/.04 Twisted Files and both GT Series X files tested were not significantly affected by the same conditions.

There are limited options for the curative treatment of refractory bone and soft tissue sarcomas. The purpose of this phase 1/2 study was to assess the immunological and clinical effects of dendritic cells (DCs) pulsed with autologous tumor lysate (TL) in patients with advanced bone and soft tissue sarcomas. Thirty-seven patients with metastatic or recurrent sarcomas were enrolled in this study. Peripheral blood mononuclear cells obtained from the patients were suspended in media containing interleukin 4 (IL-4) and granulocyte-macrophage colony-stimulating factor. Subsequently, these cells were treated with TL, tumor necrosis factor α, and OK-432. The DCs were injected into the inguinal or axillary region. One treatment course comprised 6 weekly DC injections. The toxicity, clinical response (tumor volume, serum interferon-γ [IFN-γ], and serum IL-12), and oncological outcomes were observed. In total, 47 courses of DC therapy were performed in 37 patients. No severe adverse events or deaths associated with the DC injections were observed in the study patients. Increased serum IFN-γ and IL-12 levels were observed 1 month after the DC injection. Among the 37 patients, 35 patients were assessed for clinical responses: 28 patients showed tumor progression, 6 patients had stable disease, and 1 patient showed a partial response 8 weeks after the DC injection. The 3-year overall and progression-free survival rates of the patients were 42.3% and 2.9%, respectively. Although DC therapy appears safe and resulted in an immunological response in patients with refractory sarcoma, it resulted in an improvement of the clinical outcome in only a small number of patients.

Industrial wastes have a substantial impact on coastal environments. Therefore, to evaluate the impact of cooling water discharges from coastal power plants, we studied the kinetics of the degradative processes and the ecotoxicity of two antifouling products: (1) a classic antifouling product; sodium hypochlorite (NaClO) and (2) an alternative one; aliphatic amines (commercial under the registered trade mark Mexel432). To assess the persistence of both compounds the decay of sodium hypochlorite and the primary biodegradation rate of Mexel432 were determined in natural seawater at 20 degrees C. The results indicated a more rapid decay of NaClO than Mexel432. The degradation behavior of both chemicals was described following a logistic model, which permitted calculating kinetic parameters such as t(50) or t(90). The t(50) was 1h and 2d for NaClO and Mexel432, respectively. To evaluate the potential risks of the aforementioned treatments to marine organisms, the acute toxicity of both antifouling products was studied on the microalgae Isochrysis galbana and Dunaliella salina, and on the invertebrate Brachionus plicatilis, using growth inhibition and death tests as toxic response, respectively. For I. galbana, the 96-h EC(50) values were 2.91+/-0.15mg/L of NaClO and 4.55+/-0.11mg/L of Mexel432. D. salina showed values of 96-h EC(50) of 1.73+/-0.16mg/L of NaClO and 7.21+/-0.1mg/L of Mexel432. Brachionus plicatilis showed a 24-h LC(50) of 1.23+/-0.1mg/L of NaClO and 3.62+/-0.37mg/L of Mexel432. Acute toxicity was highly dependent on the chemical and species tested. NaClO presented more toxic effects than Mexel432, also B. plicatilis was the most sensitive species in both cases. The lowest NOECs obtained, 0.25mg/L for NaClO and 2.12mg/L for Mexel432, were similar to the theoretical residual concentrations of these biocides in cooling water discharges. Therefore, these discharges can cause undesirable negative effects upon the aquatic organisms present.

Tyrosyl DNA phosphodiesterase I (Tdp1) is a member of the phospholipase D superfamily and hydrolyzes 3′phospho-DNA adducts via two conserved catalytic histidines, one acting as the lead nucleophile and the second as a general acid/base. Substitution of the second histidine specifically to arginine contributes to the neurodegenerative disease SCAN1. We investigated the catalytic role of this histidine in the yeast protein (His432) using a combination of X-ray crystallography, biochemistry, yeast genetics and theoretical chemistry. The structures of wild type Tdp1 and His432Arg both show a phosphorylated form of the nucleophilic histidine that is not observed in the structure of His432Asn. The phosphohistidine is stabilized in the His432Arg structure by the guanidinium group that also restricts access of a nucleophilic water molecule to the Tdp1-DNA intermediate. Biochemical analyses confirm that His432Arg forms an observable and unique Tdp1-DNA adduct during catalysis. Substitution of His432 by Lys does not affect catalytic activity or yeast phenotype, but substitution with Asn, Gln, Leu, Ala, Ser and Thr all result in severely compromised enzymes and Top1-camptothecin dependent lethality. Surprisingly, His432Asn did not show a stable covalent Tdp1-DNA intermediate which suggests another catalytic defect. Theoretical calculations revealed that the defect resides in the nucleophilic histidine and that the pKa of this histidine is crucially dependent upon the second histidine and the incoming phosphate of the substrate. This represents a unique example of substrate-activated catalysis that applies to the entire phospholipase D superfamily. PMID:22155078

To study, at the cytological level, the basic concept of Chinese medicine that "the Kidney (Shen) controls the bone". Kaempferol was isolated form Rhizoma Drynariae (Gu Sui Bu, GSB) and at several concentrations was incubated with opossum kidney (OK) cells, osteoblasts (MC3T3 E1) and human fibroblasts (HF) at cell concentrations of 2×10(4)/mL. Opossum kidney cell-conditioned culture media with kaempferol at 70 nmol/L (70kaeOKM) and without kaempferol (0OKM) were used to stimulate MC3T3 E1 and HF proliferation. The bone morphological protein receptors I and II (BMPR I and II) in OK cells were identified by immune-fluorescence staining and Western blot analysis. Kaempferol was found to increase OK cell growth (P<0.05), but alone did not promote MC3T3 E1 or HF cell proliferation. However, although OKM by itself increased MC3T3 E1 growth by 198% (P<0.01), the 70kaeOKM further increased the growth of these cells by an additional 127% (P<0.01). It indicates that the kidney cell generates a previously unknown osteoblast growth factor (OGF) and kaempferol increases kidney cell secretion of OGF. Neither of these media had any significant effect on HF growth. Kaempferol also was found to increase the level of the BMPR II in OK cells. This lends strong support to the original idea that the Kidney has a significant influence over bone-formation, as suggested by some long-standing Chinese medical beliefs, kaempferol may also serve to stimulate kidney repair and indirectly stimulate bone formation.

Four series of borosilicate glasses modified by alkali oxides and doped with Tb 3+ and Sm 3+ ions were prepared using the conventional melt quenching technique, with the chemical composition 74.5B 2 O 3 + 10SiO 2 + 5MgO + R + 0.5(Tb 2 O 3 /Sm 2 O 3 ) [where R = 10(Li 2 O /Na 2 O/K 2 O) for series A and C, and R = 5(Li 2 O + Na 2 O/Li 2 O + K 2 O/K 2 O + Na 2 O) for series B and D]. The X-ray diffraction (XRD) patterns of all the prepared glasses indicate their amorphous nature. The spectroscopic properties of the prepared glasses were studied by optical absorption analysis, photoluminescence excitation (PLE) and photoluminescence (PL) analysis. A green emission corresponding to the 5 D 4 → 7 F 5 (543 nm) transition of the Tb 3+ ions was registered under excitation at 379 nm for series A and B glasses. The emission spectra of the Sm 3+ ions with the series C and D glasses showed strong reddish-orange emission at 600 nm ( 4 G 5/2 → 6 H 7/2 ) with an excitation wavelength λ exci = 404 nm ( 6 H 5/2 → 4 F 7/2 ). Furthermore, the change in the luminescence intensity with the addition of an alkali oxide and combinations of these alkali oxides to borosilicate glasses doped with Tb 3+ and Sm 3+ ions was studied to optimize the potential alkali-oxide-modified borosilicate glass.

Soil respiration inherently shows strong spatial variability. It is difficult to obtain an accurate characterization of soil respiration with an insufficient number of monitoring points. However, it is expensive and cumbersome to deploy many sensors. To solve this problem, we proposed employing the Bayesian Maximum Entropy (BME) algorithm, using soil temperature as auxiliary information, to study the spatial distribution of soil respiration. The BME algorithm used the soft data (auxiliary information) effectively to improve the estimation accuracy of the spatiotemporal distribution of soil respiration. Based on the functional relationship between soil temperature and soil respiration, the BME algorithm satisfactorily integrated soil temperature data into said spatial distribution. As a means of comparison, we also applied the Ordinary Kriging (OK) and Co-Kriging (Co-OK) methods. The results indicated that the root mean squared errors (RMSEs) and absolute values of bias for both Day 1 and Day 2 were the lowest for the BME method, thus demonstrating its higher estimation accuracy. Further, we compared the performance of the BME algorithm coupled with auxiliary information, namely soil temperature data, and the OK method without auxiliary information in the same study area for 9, 21, and 37 sampled points. The results showed that the RMSEs for the BME algorithm (0.972 and 1.193) were less than those for the OK method (1.146 and 1.539) when the number of sampled points was 9 and 37, respectively. This indicates that the former method using auxiliary information could reduce the required number of sampling points for studying spatial distribution of soil respiration. Thus, the BME algorithm, coupled with soil temperature data, can not only improve the accuracy of soil respiration spatial interpolation but can also reduce the number of sampling points.

Although a direct relationship between numerical allocation and spatial attention has been proposed, recent research suggests that these processes are not directly coupled. In keeping with this, spatial attention shifts induced either via visual or vestibular motion can modulate numerical allocation in some circumstances but not in others. In addition to shifting spatial attention, visual or vestibular motion paradigms also (i) elicit compensatory eye movements which themselves can influence numerical processing and (ii) alter the perceptual state of 'self', inducing changes in bodily self-consciousness impacting upon cognitive mechanisms. Thus, the precise mechanism by which motion modulates numerical allocation remains unknown. We sought to investigate the influence that different perceptual experiences of motion have upon numerical magnitude allocation while controlling for both eye movements and task-related effects. We first used optokinetic visual motion stimulation (OKS) to elicit the perceptual experience of either 'visual world' or 'self'-motion during which eye movements were identical. In a second experiment, we used a vestibular protocol examining the effects of perceived and subliminal angular rotations in darkness, which also provoked identical eye movements. We observed that during the perceptual experience of 'visual world' motion, rightward OKS-biased judgments towards smaller numbers, whereas leftward OKS-biased judgments towards larger numbers. During the perceptual experience of 'self-motion', judgments were biased towards larger numbers irrespective of the OKS direction. Contrastingly, vestibular motion perception was found not to modulate numerical magnitude allocation, nor was there any differential modulation when comparing 'perceived' vs. 'subliminal' rotations. We provide a novel demonstration that numerical magnitude allocation can be differentially modulated by the perceptual state of self during visual but not vestibular mediated motion. © 2016 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

This 5-week study was conducted to determine the effects of Enterococcus faecium (SLB 120) on growth performance, blood parameters, relative organ weight, breast muscle meat quality, excreta microbiota shedding, and noxious gas emission in broilers. A total of 816 one-day-old male broilers were allocated to 4 groups with 12 replications (17 broilers/pen) according to body weight (43.2 ± 0.32 g). Dietary treatment groups were: (1) CON, basal diet, (2) T1, CON + 0.05% E. faecium, (3) T2, CON + 0.10% E. faecium, (4) T3, CON + 0.20% E. faecium. From day 1 to 21, dietary E. faecium supplementation showed linear increase (P < 0.05) in gain:feed ratio. From day 21 to 35 and the overall period, dietary E. faecium supplementation showed a linear increase (P < 0.05) in body weight gain and gain:feed ratio. On day 35, dietary E. faecium supplementation showed a linear increase (P < 0.05) in the apparent total tract digestibility of dry matter and nitrogen, and the relative weight of bursa of Fabricius; no differences were observed in white blood cells, red blood cells or lymphocyte counts. Dietary E. faecium supplementation showed a linear decrease (P < 0.05) in excreta E.coli counts on day 7 and 35, while excreta Lactobacillus counts were linearly increased (P < 0.05) on day 35. On day 35, dietary E. faecium supplementation linearly decreased (P < 0.05) excreta NH3, H2S, and total mercaptans emission, but only H2S emission was linearly decreased (P < 0.05) on day 7. In conclusion, the supplementation of E. faecium improved growth performance, the digestibility of dry matter and nitrogen, the relative weight of bursa of Fabricius, and shifted excreta microbiota by increasing Lactobacillus and decreasing E.coli counts, as well as decreased excreta NH3, H2S, and total mercaptans gas emission. © 2017 Poultry Science Association Inc.

The Oktay-Kronfeld (OK) action was designed to reduce heavy-quark discretization errors to below 1%, or through O(λ3) in HQET power counting. Here we describe recent progress on bottom-to-charm currents improved to the same order in HQET as the OK action, and correct formerly reported results of our matching calculations, in which the operator basis was incomplete.

This study examined the effect of optokinetic stimulation on objective sleepiness, as measured by the Multiple Sleep Latency Test (MSLT). The Nightcap, a portable sleep monitor, was used in a novel way to perform MSLTs, as well as record sleep in the home. Subjects wore the Nightcap for seven consecutive nights. On days 3 and 5 of the protocol, subjects came into the lab for an MSLT. On the experimental day, subjects underwent 10 minutes optokinetic stimulation (OKS), resulting in moderate motion sickness prior to each MSLT trial. Although subjects in the OKS condition reported significantly more drowsiness than controls, this did not result in significantly reduced sleep latencies.

Hyperglycemia-induced oxidative stress is widely recognized as a key mediator in the pathogenesis of diabetic nephropathy, a complication of diabetes. We found that both expression and enzymatic activity of cytosolic NADP(+)-dependent isocitrate dehydrogenase (IDPc) were upregulated in the renal cortexes of diabetic rats and mice. Similarly, IDPc was induced in murine renal proximal tubular OK cells by high hyperglycemia, while it was abrogated by co-treatment with the antioxidant N-Acetyl-Cysteine (NAC). In OK cells, increased expression of IDPc by stable transfection prevented hyperglycemia-mediated reactive oxygen species (ROS) production, subsequent cellular oxidative stress and extracellular matrix accumulation, whereas these processes were all stimulated by decreased IDPc expression. In addition, production of NADPH and GSH in the cytosol was positively correlated with the expression level of IDPc in OK cells. These results together indicate that upregulation of IDPc in response to hyperglycemia might play an essential role in preventing the progression of diabetic nephropathy, which is accompanied by ROS-induced cellular damage and fibrosis, by providing NADPH, the reducing equivalent needed for recycling reduced glutathione and low molecular weight antioxidant thiol proteins.

The Turkish Family Health and Planning Foundation set out with the support of the US Agency for International Development in 1988 to develop a contraceptive social marketing program. It was designed to increase the availability and use of condoms and low-dose pills, while maximizing the participation of the private sector. The program would build a market using existing infrastructure; collaborate and participate with 4 major pharmaceutical companies; use all commercial products and nothing donated; and negotiate for commercial product prices without subsidy. Full cost recovery and self-sufficient operation was projected to be realized by the 4th year of sales. The OK condom brand was created for the program and marketed through television, open air advertisements, gifts, and sponsorship from mid-1991. 4.46 million units were sold over the period May-December 1991 and 5.76 million over January-November 1992; these figures were 127% and 115% above sales targets, respectively. The OK brand dominated the market of everusers with 41.1% having employed the brand. Data suggest that the condoms are effectively being used by the urban and comparatively poor segments of society. Sales volumes were so robust that the commercial sector expanded the product line on its own to offer OK Extra.

The ability to predict patients' functional outcomes will add value to preoperative counseling. The purpose of this study was to evaluate predictors of good outcomes following total knee arthroplasty (TKA) among Asian patients. Registry data from 2006 to 2010 were extracted. The Oxford Knee Score (OKS) and the Short Form (SF)-36 physical component summary (PCS) were used to evaluate outcomes. A "good outcome" was defined as an improvement in scores of greater than or equal to the minimal clinically important difference (MCID) in the primary analysis. The MCID for the OKS was 5, and the MCID for the PCS was 10. For the sensitivity analyses, a "good outcome" was defined as an OKS of <30 and a PCS score of >50. Clinical variables were used to develop a multiple logistic regression model for a good outcome following total knee arthroplasty at 5 years. Follow-up data were available for 3,062 patients who underwent primary TKA (mean age of 66.4 years; 79.5% female). Eighty-five percent had a good outcome on the basis of the OKS and 83%, on the basis of the SF-36 PCS. Age and preoperative Knee Society score (KSS) were found to be significant predictors. When outcomes were assessed by the MCID, lesser age and lower (worse) preoperative KSS predicted a good outcome at 5 years. When outcomes were assessed by absolute criteria (postoperative scores measured against OKS and PCS thresholds), a higher (better) preoperative KSS predicted a good outcome at 5 years. Body mass index, preoperative flexion range, SF-36 mental component summary (MCS) score, mechanical alignment, sex, education level, ethnicity, operative side, number of comorbidities, type of anesthesia, and type of implant were found not to be significant predictors. The majority of Asian patients with osteoarthritis had good outcomes according to the MCID criterion and benefitted from primary TKA. On the basis of our findings, we believe that older patients with a lower (worse) preoperative KSS can be informed that they have a high likelihood of improvement but a lower likelihood of achieving as good a functional outcome as those with better scores.

Lateral variation of H2O/K2O ratios in Quaternary Magma of the Northeastern Japan arc

NASA Astrophysics Data System (ADS)

Miyagi, I.

2012-12-01

Water plays a fundamental role in the magma genesis beneath subduction zones. In order to estimate a spatial distribution of the density of water flux in the wedge mantle of the Northeastern Japan arc, this study examines a lateral variation of pre-eruptive bulk rock H2O/K2O contents among volcanoes located both in the frontal and in back arc settings. The analytical targets are the frontal volcanoes Nigorikawa (N42.12 E140.45), Zenikame (N41.74 E140.85), Adachi (N38.22 E140.65), and Nanashigure (N40.07 E141.11), and the back arc ones Hijiori (N38.61 E140.17) and Kanpu (N39.93 E139.88). The bulk magmatic H2O content (TH2O) is calculated from a mass balance of hydrogen isotopic ratios among three phases in a batch of magma; dissolved water in melt, excess H2O vapor, and hydrous phenocrysts such as amphiboles (Miyagi and Matsubaya, 2003). Since the amount of H2O in hydrous phenocryst is negligible, the bulk magmatic H2O content can be written as TH2O = (30 XD CD) / (15 - dT + dMW), where dMW is the measured hydrogen isotopic ratio of hydrous phenocrysts, XD is a melt fraction of magma, CD is a water concentration of the melt, and dT is hydrogen isotopic ratios of a bulk magma (assumed to be -50 per-mil). Both XD and CD are estimated from bulk rock chemistry of the sample using the MELTS program (Ghiorso and Sack, 1995). Hydrogen isotopic fractionation factors are assumed to be -15 and -30 per-mil for vapor and hydrous mineral, and vapor and silicate melt, respectively. There observed a clear difference among the H2O/K2O ratios of bulk magmas from the frontal and back arc volcanoes. For instance higher H2O/K2O wt ratios was observed in the frontal volcanoes (Nigorikawa 5.3, Zenikame 11-12, Adachi 8-10, and Nanashigure 4-18), while lower H2O/K2O wt ratios was observed in the back arc ones (Kanpu 0-2.5 and Hijiori 1.4). The lateral variation of H2O/K2O ratios infer the higher water flux through the frontal side of wedge mantle, which can be a potential cause of the larger quantity of volcanic products along the frontal side of the NE Japan arc. This research project has been conducted under the research contract with Nuclear and Industrial Safety Agency (NISA). I thank Drs. H. Kawaraya, D. Ishiyama, and O. Matsubaya at Akita univ. for their help in the analysis of hydrogen isotopic ratios.

This research was conducted to study the performance and carcass parameters of broiler chickens fed diets supplemented with heat-treated non-starch polysaccharide degrading enzyme. A total of 432 one-day old Ross 308 broiler chickens were allocated to five treatments: (i) CON (basal diet), (ii) E1: CON + 0.05% multi-enzyme, (iii) E2: CON + 0.1% multi-enzyme, (iv) E3: CON + 0.05% thermo-resistant multi-enzyme and (v) E4: CON + 0.1% thermo-resistant multi-enzyme, each treatment consisted of six replications and 12 chickens in each replication. The chickens were housed in three floor battery cages during 28-day experimental period. On days 1-7, gain in body weight (BWG) improved by feeding the diets supplemented with thermo-resistant multi-enzyme. On days 7-21 and 1-28, chickens fed the diets containing thermo-resistant multi-enzyme showed improved (p < 0.05) BWG and feed conversion ratio (FCR) compared to CON group. Supplementing the diets with multi-enzyme or thermo-resistant multi-enzyme affected the percentage of drip loss on d 1 (p < 0.05). Drip loss percentage on days 3 and 5 and also meat colour were not affected significantly. Supplementing the diets with multi-enzyme or thermo-resistant multi-enzyme did not affect the relative weights of organs but compared to CON group, relative weight of breast muscle increased and abdominal fat decreased (p < 0.05). Among measured blood constituents, chickens fed supplemented diets with thermo-resistant multi-enzyme showed higher (p < 0.05) IgG. Counts of red and white blood cells and lymphocyte percentage were not affected. In conclusion, the results demonstrated that supplementing pelleted diets with thermo-resistant multi-enzyme improved performance of broiler chickens.

The Changing Pattern of the Splenic Lymphocyte Subsets in Tumor‐bearing Mice after Oral Treatment with OK‐432

PubMed Central

Fuchimoto, Sadanori; Orita, Kunzo

1992-01-01

The aim of this study was to investigate the influence of oral administration of OK‐432 on the tumor growth of tumor‐bearing mice. In addition, the changing pattern of the splenic lymphocyte subsets of tumor‐bearing mice was evaluated by flow cytometry. OK‐432 at a dose of 0.1, 1 or 10 KE was administered orally every 3 days or every other day for 30 days to subcutaneously Meth A tumor‐inoculated mice. The tumor growth was significantly inhibited in the 1 KE every 3 days group, in the 1 KE every other day group and in the 10 KE every 3 days group. In the 10 KE every other day group, OK‐432 inhibited the tumor growth on days 10 and 20, while the agent did not show a marked inhibitory effect on day 30. The percentages of splenic L3T4‐positive cells and splenic asialo GM1‐positive cells were significantly increased in the 1 KE every other day group, while the Lyt2+/ Thyl.2+ratio was decreased. On the other hand, in the 10 KE every other day group, OK‐432 showed no effect on the percentages of splenic L3T4‐positive cells and Lyt2+/Thyl.2+ratio on days 20 and 30. Our results suggest that the antitumor effect of oral administration of OK‐432 may be correlated with the changing pattern of L3T4‐positive cells and Lyt2+/Thyl.2+ratio. PMID:1353756
