    A 68-year-old male with macroscopic hematuria and constitutional symptoms as fever and weight loss. There was nothing interesting in the anamnesis or in the physical exploration. The laboratory test had an elevation of creatinine of 4 mg/dL and ten days before it had been 1.4 mg/dL. In the urine analysis: proteinuria of 1.5 G/24 h, and hematuria. On the second day we made a renal biopsy where we could seen segmental glomerular necrosis and crescent fromation in 80% of the glomeruli. In the immune study c-ANCA anti-PR3 was positive. In the complementary studies we didn't find other organs affected. With the diagnosis of pauci-immune glomerulonephritis limited to the kidney we began treatment with corticosteroids and cyclophosphamide. As the renal function was severely affected the patient needed one dialysis session. We began with 1 g intravenous methylprednisolone daily for 3 days followed by oral prednisone 60 mg daily tapering to 10 mg daily by 3 months. This was combined with 150 mg oral cyclophosphamide daily. Seven plasma exchanges were performed. At the beginning of treatment creatinine was 7 mg/dL, it was decreasing rapidly and three week after cretinine was 3 mg/Dl and he was asymptomatic. One year after treatment, creatinine is 1.4 mg/dL and the urine analysis is normal, C-ANCA are negative.

    Anomalous left coronary artery from the pulmonary artery (ALCAPA), or Bland-White-Garland syndrome, is a rare congenital coronary anomaly that results in altered myocardial perfusion and a left to right shunt. It occurs in 1:300000 live births and represents 0.24% to 0.46% of all congenital cardiac diseases. Despite its rarity, it is one of the most common causes of ischemia and infarction in children. Ninety percent of these patients will die within the first year of life if untreated and diagnosing this abnormality in adulthood is extremely rare. Of those patients who survive to adulthood, the average age of sudden cardiac death is 35 years. The initial symptoms of the adult presentation vary widely from progressive dyspnea to sudden cardiac death; therefore, immediate surgical correction is highly recommended upon diagnosis. Understanding the pathophysiology and nature of collateral coronary flow in this congenital anomaly is paramount to the safe anesthetic management of adults with ALCAPA. Here we describe the intraoperative management and echocardiographic findings in a 68-year-old with with recently diagnosed ALCAPA undergoing surgical repair.

    Introduction Takotsubo cardiomyopathy also known as transient left ventricular apical ballooning, stress-induced cardiomyopathy can present with retrosternal chest pain with EKG changes that can mimic a myocardial infraction. Case Presentation We present a 68 female with sudden onset retrosternal squeezing chest pain with positive cardiac enzymes and EKG changes suggestive of acute ST-elevation myocardial infraction. Patient was thrombolysed and cardiac cauterization done later showed normal coronaries with ballooning of the left ventricle apex. Conclusion Takotsubo cardiomyopathy is a very rare disease entity yet can present to the emergency room as acute myocardial infraction. PMID:18662406

    Fibroadenoma of the breast is an uncommon cause of breast lumps in men. Only a few cases have been reported in the literature, the majority of which were prescribed estrogen. We present herein the first case of a fibroadenoma of the breast in a 68-year-old man with adenocarcinoma of the rectum and polyposis coli. In this case, there was neither estrogen treatment nor any other medications which have been discussed in the literature as inducing fibroadenomas. Fibroadenomas in men without hormone treatment and with normal hormone levels are extremely rare and the developmental mechanism of the breast fibroadenoma in this man is under question.

    There are few reported cases of colorectal metastasis from cancers of other organs, particularly other segments of the colon. Here we describe the long-term survival of a 68-year-old male patient with metachronous rectal metastasis from cecal cancer who underwent repetitive resection and chemotherapy. The patient underwent ileocecal resection and hepatectomy for cecal cancer with liver metastasis (T3, N1a, M1a, Stage IVA) in 2006. The patient subsequently underwent splenectomy for splenic metastasis in 2007. In August 2008, barium enema revealed compression of the rectal wall, and abdominal computed tomography (CT) detected a mass along the rectum extending into the pelvis. Rectal metastasis from cecal cancer was suspected and Hartmann's operation with bilateral seminal vesicle dissection was performed. Histological examination of the excised tumor revealed moderately differentiated adenocarcinoma formed in the muscularis propria of the rectum and infiltrating the connective tissue between the seminal vesicle and rectum. However, no tumor was detected in the rectal mucosa or submucosa. These histological findings supported the diagnosis of rectal metastasis from cecal cancer. The patient has been monitored at our clinic for 60 months after surgical removal of the rectal metastasis. The findings from this case should alert oncologists to the potential danger of rectal metastasis from primary colon cancer and the benefits of timely complete resection in terms of improved patient outcomes.

    The association between eating behaviour and dietary factors has been studied narrowly in children. Therefore, we investigated whether eating frequency and food consumption are influenced by eating behaviour in a population sample of 406 children aged 6-8 years. We assessed features of eating behaviour by the Children's Eating Behaviour Questionnaire and dietary factors by a 4-day food record. The results showed that enjoyment of food was directly associated with a number of main meals (p = 0.041) and consumption of vegetables (p = 0.041), cheese (p = 0.005), and meat (p = 0.002). Food responsiveness was directly associated with consumption of fruit and berries (p = 0.013) and meat (p = 0.016). Desire to drink was directly associated with consumption of fat-containing milk (p = 0.002) and inversely associated with consumption of skimmed milk (p = 0.001). Food fussiness was inversely associated with a number of main meals (p = 0.013) and consumption of vegetables (p < 0.001), cheese (p = 0.001), and meat (p = 0.027). Satiety responsiveness was inversely associated with consumption of vegetables (p = 0.031), cheese (p = 0.010), and meat (p < 0.001) and directly associated with consumption of candies and chocolate (p = 0.026). Slowness in eating was inversely associated with consumption of meat (p = 0.018). Where sex differences existed the associations tended to be observed mostly in girls but not in boys. Our study shows that enjoyment of food and food responsiveness are directly associated with consumption of protein-rich foods and vegetables, fruit and berries, whereas food fussiness and satiety responsiveness are inversely associated with consumption of these foods. Assessment of eating behaviour can help in identifying children with various dietary needs.

  8. Evaluation of retention of pit and fissure sealants placed with and without air abrasion pretreatment in 6-8 year old children – An in vivo study

    Background The success of pit and fissure sealants is directly related to their retention. The purpose of this study was to assess and compare the retention of pit and fissure sealants placed using acid etch alone and a combination of air abrasion and acid etch techniques. Material and Methods 50 subjects aged 6-8 years were included in the study. Primary second molars and permanent first molars were sealed in all four quadrants using split mouth design. The right maxillary and mandibular molars (Group A) were treated by acid etching alone while the left maxillary and mandibular molars (Group B) were pretreated with air abrasion followed by acid etching before application of pit and fissure sealant. Retention of sealants was checked using Simonsen’s criteria of sealant retention after three and six months of sealant application. Results There was no significant difference in retention of sealants in Group A and Group B (p<0.05) after three and six months follow up. The difference in sealant retention in primary and permanent molars was not significant (p>0.05). Maxillary molars showed superior retention compared to mandibular molars, which was statistically significant at both three and six months (p<0.05). Conclusions Combining air abrasion pretreatment with subsequent acid etching did not result in statistically significant difference in sealant retention compared to acid etching alone in both primary and permanent molars after 3 and 6 months follow up. An additional air abrasion pretreatment step can be avoided in pediatric patients when placing sealants and the procedure can be completed faster with better behavior management using acid etching alone. Key words:Pit and fissure sealant, acid etching, air abrasion. PMID:28210438

    In the 1950s and 1960s, Wernher von Braun was famous as the man who led the West's journey into space. Some also remember him as the German engineer who developed the V-2 missile that bombarded Antwerp and London at the end of the Second World War. However, many still celebrate Von Braun, who died in 1977, as the man who put the astronauts on the Moon. While this is not strictly true, there is no doubt that Von Braun was one of the most influential engineers, lobbyists and personalities in the Moon-landing project.

  10. Remeasuring man.

    Weisberg, Michael

    2014-05-01

    Samuel George Morton (1799-1851) was the most highly regarded American scientist of the early and middle 19th century. Thanks largely to Stephen Jay Gould's book The Mismeasure of Man, Morton's cranial capacity measurements of different races is now held up as a prime example of and cautionary tale against scientific racism. A team of anthropologists recently reevaluated Morton's work and argued that it was Gould, not Morton, who was biased in his analysis. This article is a reexamination of the Morton and Gould controversy. It argues that most of Gould's arguments against Morton are sound. Although Gould made some errors and overstated his case in a number of places, he provided prima facia evidence, as yet unrefuted, that Morton did indeed mismeasure his skulls in ways that conformed to 19th century racial biases. Gould's critique of Morton ought to remain as an illustration of implicit bias in science.

    A remaining uncertainty in the U.S. cohort study of man-made vitreous fiber (MMVF) workers is whether asbestos exposure contributed to 10 questionable cases of mesothelioma. We report further details on one case from our previous mesothelioma investigation, including results of a recent lung tissue analysis. Case is a 68 year-old white male employed 1951-54 in a rock/slag wool plant where asbestos-containing products were manufactured. Cause of death was recorded as "mesothelioma, malignant, right pleural cavity" (ICD9: 163.9). Analysis for presence of asbestos bodies identified 18,300 asbestos bodies per gram of wet lung tissue (AB/gm), which greatly exceeds the normal range of 0-20 AB/gm. No MMVFs were identified in this sample. We conclude that this patient's tumor was not a mesothelioma, but a carcinoma possibly arising in the lung or mediastinum, and that this case supports the view that the few suspected mesotheliomas found in the U.S. cohort may have been caused by asbestos exposure.

    The contemporary presence of organomegaly, skin manifestations, polyneuropathy, endocrinopathy and monoclonal component characterises the POEMS syndrome, often associated with osteosclerotic myeloma and Castelman's disease and more frequent in the Japanese. Clinical manifestations seem to be related to the production of many interleukins, mainly IL-1, IL-6 and TNF. Several endocrinopathies have been described, the most frequent being diabetes. Only one previous case of hypoparathyroidism associated with the syndrome has been described in medical reviews. Polyneuropathy is often sensitivo-motory and skin disease accounts for Raynaud phenomenon, skin pigmentation, hypertricosis and others. We describe the case of a 74-year-old man who underwent clinical examination for weakness mainly in the legs. Clinical and instrumental data showed rhabdomyolysis due to hypoparathyroidism. The contemporary presence of a monoclonal band of light chains on proteic electrophoresis, organomegaly and distal leg neuropathy allowed us to make a diagnosis of POEMS syndrome.

    An overview of the conceptual design of manned engineering satellites is presented. The mission scenarios for developing manned engineering satellites involve: (1) selecting mission equipment to enable preferential development and validation of mandatory technologies among those for Environmental Control and Life Support System (ECLSS); (2) selecting mission equipment to enable development and validation of independent domestic technologies as well as utilizing to the utmost the manned space technology acquired through the Japanese Experimental Module (JEM); and (3) installing the most effective mission on the basis of relationships with Extravehicular Activity (EVA), robot, and retrieval-type spacecraft technologies, and trends of overseas manned space technology. The results of reviews on the system and subsystems, such as attitude and orbit control, structure, thermal control, electric power, communication, and data processing subsystems are outlined. The results of reviews on the structure, weight, and reentry phase operation are presented.

  4. Symbolism in prehistoric man.

    Facchini, F

    2000-12-01

    The aptitude for symbolization, characteristic of man, is revealed not only in artistic representations and funerary practices. It is exhibited by every manifestation of human activity or representation of natural phenomena that assumes or refers to a meaning. We can recognize functional symbolism (tool-making, habitative or food technology), social symbolism, (language and social communication) and spiritual symbolism (funerary practices and artistic expressions). On the basis of these concepts, research into symbolism in prehistoric man allows us to recognize forms of symbolism already in the manifestations of the most ancient humans, starting with Homo habilis (or rudolfensis). Toolmaking, social organization and organization of the territory are oriented toward survival and the life of the family group. They attest to symbolic behaviors and constitute symbolic systems by means of which man expresses himself, lives and transmits his symbolic world. The diverse forms of symbolism are discussed with reference to the different phases of prehistoric humanity.

    We report a case of benign senile seminal vesicle amyloidosis demonstrating intense Ga-prostate-specific membrane antigen (PSMA) uptake on PET/CT. A 68-year-old man underwent staging PSMA PET/CT and MRI for biopsy-proven prostate adenocarcinoma. There was an intense focus of Ga-PSMA uptake in the primary malignancy, as well as symmetrical intense uptake in the seminal vesicles bilaterally that was reported as multifocal disease with local invasion. Final histology after radical prostatectomy showed amyloidosis of the seminal vesicles without any evidence of prostate cancer. Care should be taken in the interpretation of seminal vesicle PSMA uptake to avoid overstaging.

    Perineal hernia is an uncommon complication following abdominoperineal rectum resection. Several surgical procedures have been proposed for perineal hernia repair, including perineal, laparoscopic and abdominal approaches. Repair techniques can be classified into primary suture techniques, mesh placements and repairs with autogenous tissue. We report a 68-year-old man with a perineal hernia, who underwent a pelvic floor reconstruction with a transperineal composite mesh and a gluteal fasciocutaneous rotation flap. We conclude that a combined approach with transperineal mesh reconstruction and gluteal fasciocutaneous flap could be an alternative choice in perineal hernia repair after abdominoperineal resection.

    With advances of combined modality therapy, prognoses in esophageal cancer have been improving. After resection of esophageal cancer, the development of gastric tube cancer is a risk. While such cancer in an early stage can be cured endoscopically, total gastric tube resection is indicated in advanced stages. A 68-year-old man underwent subtotal esophagectomy reconstructed with a gastric tube through the retrosternal route. Gastric cancer was found one and a half years postoperatively. The gastric tube was resected without sternotomy. This is the first report of a patient undergoing resection of the gastric tube reconstructed through the retrosternal route without sternotomy.

    The 70-kg Standard Man or Reference Man has been used in physiological models since at least the 1920s to represent adult males. It came into use in radiation protection in the late 1940s and was developed extensively during the 1950s and used by the International Commission on Radiological Protection (ICRP) in its Publication 2 in 1959. The current Reference Man for Purposes of Radiation Protection is a monumental book published in 1975 by the ICRP as ICRP Publication 23. It has a wealth of information useful for radiation dosimetry, including anatomical and physiological data, gross and elemental composition of the body and organs and tissues of the body. The anatomical data includes specified reference values for an adult male and an adult female. Other reference values are primarily for the adult male. The anatomical data include much data on fetuses and children, although reference values are not established. There is an ICRP task group currently working on revising selected parts of the Reference Man document.

  18. Typhoon Man-Yi

    2007-01-01

    Typhoon Man-Yi was pummeling the Japanese island of Okinawa with winds between 230 and 295 kilometers per hour (125-160 knots, 144-184 miles per hour) and heavy rain on the morning of July 13, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image. The immense storm covered hundreds of kilometers with spiraling bands of thunderstorms, though it had lost the distinctive cloud-free eye it exhibited the day before. Typhoons are common in Japan, but powerful typhoons usually strike the island nation later in the year. The Japan Meteorological Agency said that Man-Yi is the fourth typhoon of the 2007 season and may be the most powerful ever observed in the northwest Pacific in July, reported Kyodo News. The Joint Typhoon Warning Center expected the typhoon to strike Kyushu, a southern Japanese island, on July 14, and then curve northeast along the eastern shore of Japan. By the time the storm reaches Tokyo on July 15, it should be degraded to a tropical storm. As of July 13, Typhoon Man-Yi had injured eight and flooded twenty houses in Okinawa, and forced airlines to cancel hundreds of flights, said Kyodo News. The storm was expected to bring heavy rain to Japan's Pacific coast. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response team.

    A 65-year-old man with non-ischemic cardiomyopathy, underwent an autopsy 2 months after the successful ablation of a sustained left ventricular (LV) summit ventricular tachycardia (VT). The patient died due to interstitial pneumonia from amiodarone use. The earliest activation sites of the VT were documented from both inside the anterior interventricular vein (AIV) and epicardial surface. The diameter of the AIV was 3-4 mm, and the radiofrequency (RF) lesion inside the AIV was a slight lesion due to high impedance with a high temperature. The lesion from the epicardial surface was also superficial and insufficient due to neighboring coronary arteries and the existence of epicardial fat. A successful application was performed from the LV endocardium, and diffuse myocardial fibrosis was observed in the mid-myocardium including inside the RF lesions. The actual relationship between the myocardial fibrosis and LV summit VT remains unclear, but this case showed the difficulty of achieving a successful ablation from the epicardial side, when the focus exists in the mid-myocardium around the LV summit.

    Manned orbiting stopover round trips to Venus are studied for departure dates between 1975 and 1986 over a range of trip times and stay times. The use of highly elliptic parking orbits at Venus leads to low initial weights in Earth orbit compared with circular orbits. For the elliptic parking orbit, the effect of constraints on the low altitude observation time on the initial weight is shown. The mission can be accomplished with the Apollo level of chemical propulsion, but advanced chemical or nuclear propulsion can give large weight reductions. The Venus orbiting mission weights than the corresponding Mars mission.

    The resiliency and adaptive ability of microbial life in real time on Earth relies heavily upon horizontal gene transfer. Based on that knowledge, how likely is earth based microbial life to colonize extraterrestrial targets such as Mars? To address this question, we consider manned and unmanned space exploration, the resident microbiota that is likely to inhabit those vehicles, the adaptive potential of that microbiota in an extraterrestrial setting especially with regards to mobile genetic elements, and the likelihood that Mars like environments could initiate and sustain colonization.

    A viable power system technology for a surface transportation vehicle to explore the planet Mars is presented. A number of power traction systems were investigated, and it was found that a regenerative hydrogen-oxygen fuel cell appears to be attractive for a manned Mars rover application. Mission requirements were obtained from the Manned Mars Mission Working Group. Power systems weights, power, and reactants requirements were determined as a function of vehicle weights for vehicles weighing from 6,000 to 16,000 lb (2,722 to 7,257 kg), (Earth weight). The vehicle performance requirements were: velocity, 10 km/hr; range, 100 km; slope climbing capability, 30 deg uphill for 50 km; mission duration, 5 days; and crew, 5. Power requirements for the operation of scientific equipment and support system capabilities were also specified and included in this study. The concept developed here would also be applicable to a Lunar based vehicle for Lunar exploration. The reduced gravity on the Lunar surface, (over that on the Martian surface), would result in an increased range or capability over that of the Mars vehicle since many of the power and energy requirements for the vehicle are gravity dependent.

    The development and establishment of a manned space station represents the next major U.S. space program after the Space Shuttle. If all goes according to plan, the space station could be in orbit around the earth by 1992. A 'power tower' station configuration has been selected as a 'reference' design. This configuration involves a central truss structure to which various elements are attached. An eight-foot-square truss forms the backbone of a structure about 400 feet long. At its lower end, nearest the earth, are attached pressurized manned modules. These modules include two laboratory modules and two so-called 'habitat/command' modules, which provide living and working space for the projected crew of six persons. Later, the station's pressurized space would be expanded to accommodate up to 18 persons. By comparison, the Soviets will provide habitable space for 12 aboard a 300-ton station which they are expected to place in orbit. According to current plans the six U.S. astronauts will work in two teams of three persons each. A ninety-day tour of duty is considered.

    Objective The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden) heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump) as compared to Group 2 (off-pump). But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893), P>0.05 for bilateral pleural effusion (P=0.780)]. Left pleural effusion was encountered to be lower in Group 2 (off-pump). The difference was found to be statistically significant (P<0.05, P=0.006). Conclusion Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Light in the form of solar radiation influenced early civilisations and resulted in the independent development of a number of sun-worshipping dieties. These were of particular importance as hunter gatherers transformed into settled agricultural societies. All artificial light sources were synonymous with fire, and early civilisations began to expand their visual day by burning brands, oil, and candles. Fire-based light sources extended for thousands of years and were still present in the era of gas lighting. Light meant fire risk. The advent of incandescent bulbs and the era of electric lighting really only expanded in the early part of the twentieth century. Fluorescent lighting became available in the 1940s, and today the drive for low energy has resulted in a plethora of novel light sources—in particular, light-emitting diodes (LEDs). Evolution governed the development of the eye in relation to roughly 12 h of light gradually changing to 12 h of darkness. Today almost daylight levels can be achieved abruptly at the flick of a switch. Many studies have demonstrated the spectral dependence of eye health, with the retinal hazard zone associated with wavelengths in the blue, peaking at 441 nm— many of today's low-energy sources peak in this region. Given the increased longevity and artificial light sources emitting at biologically unfriendly wavelengths, attention has to be directed towards light in man's environment as a risk factor in age-related ocular diseases.

    Particle concentration measurements with underwing probes on aircraft are impacted by air compression upstream of the instrument body as a function of flight velocity. In particular for fast-flying aircraft the necessity arises to account for compression of the air sample volume. Hence, a correction procedure is needed to invert measured particle number concentrations to ambient conditions that is commonly applicable for different instruments to gain comparable results. In the compression region where the detection of particles occurs (i.e. under factual measurement conditions), pressure and temperature of the air sample are increased compared to ambient (undisturbed) conditions in certain distance away from the aircraft. Conventional procedures for scaling the measured number densities to ambient conditions presume that the particle penetration speed through the instruments' detection area equals the aircraft speed (True Air Speed, TAS). However, particle imaging instruments equipped with pitot-tubes measuring the Probe Air Speed (PAS) of each underwing probe reveal PAS values systematically below those of the TAS. We conclude that the deviation between PAS and TAS is mainly caused by the compression of the probed air sample. From measurements during two missions in 2014 with the German Gulfstream G-550 (HALO - High Altitude LOng range) research aircraft we develop a procedure to correct the measured particle concentration to ambient conditions using a thermodynamic approach. With the provided equation the corresponding concentration correction factor ξ is applicable to the high frequency measurements of each underwing probe which is equipped with its own air speed sensor (e.g. a pitot-tube). ξ-values of 1 to 0.85 are calculated for air speeds (i.e. TAS) between 60 and 260 m s-1. From HALO data it is found that ξ does not significantly vary between the different deployed instruments. Thus, for the current HALO underwing probe configuration a parameterisation of

    1995-02-01

    Poor man`s parallelism is a term to describe the harnessing of commonly available computational approaches containing a high degree of implicit or explicit parallelism with distributed computer resources to produce a large gain in processing time. The distinguishing features of poor man`s techniques are their accessibility and relatively low cost. In some circumstances, the clever exploitation of existing hardware and software may achieve as much improvement in the timely completion of tasks as do high-end, state-of-the-art parallel technologies. The ANN-GA approach to the optimization of environmental remediation strategies is an example of poor man`s parallelism: it integrates two well-known computational technologies, artificial neural networks (ANNs) and the genetic algorithm (GA), with a simple scheme for exploiting a network of Unix workstations to solve a nonlinear combinatorial optimization problem. Although this work has been motivated by the need to tame a computational tiger rather than to experiment with different flavors of parallelism, the approach has reached a level of maturity where it is instructive to examine how parallelism is embodied in its various components. It also stands as a demonstration of how even resource-lean organizations can take advantage of parallelism to solve problems.

    The potential costs of several options of a manned Mars mission are examined. A cost estimating methodology based primarily on existing Marshall Space Flight Center (MSFC) parametric cost models is summarized. These models include the MSFC Space Station Cost Model and the MSFC Launch Vehicle Cost Model as well as other modes and techniques. The ground rules and assumptions of the cost estimating methodology are discussed and cost estimates presented for six potential mission options which were studied. The estimated manned Mars mission costs are compared to the cost of the somewhat analogous Apollo Program cost after normalizing the Apollo cost to the environment and ground rules of the manned Mars missions. It is concluded that a manned Mars mission, as currently defined, could be accomplished for under $30 billion in 1985 dollars excluding launch vehicle development and mission operations.

    The objective of the present work was to study peculiarities of the analgesic action of therapeutic electrical stimulation (TES therapy) in the early postoperative period in the patients who underwent tonsillectomy. A total of 60 patients admitted for this surgery to the specialized otorhinolaryngological department were available for observation. They were divided into two groups depending on the pain relief strategy. The patients of the study group (n=30) underwent courses of transcranial electrical stimulation on a daily basis (from the onset of hospitalization) in addition to the administration of a standard analgetic. The standard dose of tramadol (2.0 ml) was given to the patients of the control group (n=30) who complained of strong pain. The results of the objective and subjective estimations indicate that the degree of pharyngeal pain in the patients treated with TES therapy and the standard analgetic was significantly different. The patients receiving TES therapy could sooner resume their habitual diet and required smaller amounts of the analgetic which makes this modality a cost-effective supplement to the standard postoperative treatment.

    Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD) newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB), has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN) measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P < 0.01) during CPB and at the end of the surgical procedure. Moreover, ADN showed a flat pattern and no significant differences (P > 0.05) have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Abstract To evaluate the clinicopathological characteristics and factors that lead to residual tumors in patients who underwent additional gastrectomy for incomplete endoscopic resection (ER) for early gastric cancer (EGC). Between 2003 and 2013, the medical records of patients underwent additional gastrectomy after incomplete ER were retrospectively reviewed. Those diagnosed with the presence of histologic residual tumor in specimens obtained by gastrectomy were assigned to the residual tumor (RT) group (n = 47); those diagnosed with the absence of histologic residual tumor were assigned to the nonresidual tumor (NRT) group (n = 33). In the multivariate analysis, endoscopic piecemeal resection, Helicobacter pylori infection, large tumor size (>2 cm), and both (lateral and vertical) marginal involvement were independent factors of the presence of residual tumor in additional gastrectomy after incomplete resection ER for EGC and the rates of independent factors were significantly higher in the RT group than in the NRT group (P < 0.05). Before ER, preexamination to accurately determine the GC invasion depth and the presence of LN metastasis is very important. During ER, surgeons should attempt to perform en bloc resection and to resect the mucous membrane with adequate safety margins to prevent tumor invasion into the lateral and vertical margins.

    ABSTRACT Objective To evaluate the incidence of Y-chromosome microdeletions in individuals born from vasectomized fathers who underwent vasectomy reversal or in vitro fertilization with sperm retrieval by epididymal aspiration (percutaneous epididymal sperm aspiration). Methods A case-control study comprising male children of couples in which the man had been previously vasectomized and chose vasectomy reversal (n=31) or in vitro fertilization with sperm retrieval by percutaneous epididymal sperm aspiration (n=30) to conceive new children, and a Control Group of male children of fertile men who had programmed vasectomies (n=60). Y-chromosome microdeletions research was performed by polymerase chain reaction on fathers and children, evaluating 20 regions of the chromosome. Results The results showed no Y-chromosome microdeletions in any of the studied subjects. The incidence of Y-chromosome microdeletions in individuals born from vasectomized fathers who underwent vasectomy reversal or in vitro fertilization with spermatozoa recovered by percutaneous epididymal sperm aspiration did not differ between the groups, and there was no difference between control subjects born from natural pregnancies or population incidence in fertile men. Conclusion We found no association considering microdeletions in the azoospermia factor region of the Y chromosome and assisted reproduction. We also found no correlation between these Y-chromosome microdeletions and vasectomies, which suggests that the assisted reproduction techniques do not increase the incidence of Y-chromosome microdeletions.

    Meralgia paresthetica is commonly caused by a focal entrapment of lateral femoral cuteneous nerve while it passes the inguinal ligament. Common symptoms are paresthesias and numbness of the upper lateral thigh area. Pregnancy, tight cloths, obesity, position of surgery and the tumor in the retroperitoneal space could be causes of meralgia paresthetica. A 29-year-old female patient underwent an emergency cesarean section under spinal anesthesia without any problems. But two days after surgery, the patient complained numbness and paresthesia in anterolateral thigh area. Various neurological examinations and L-spine MRI images were all normal, but the symptoms persisted for a few days. Then, electromyogram and nerve conduction velocity test of the trunk and both legs were performed. Test results showed left lateral cutaneous nerve injury and meralgia paresthetica was diagnosed. Conservative treatment was implemented and the patient was free of symptoms after 1 month follow-up. PMID:21286469

    Abstract Background: This prospective, randomized, and controlled study was performed to determine the benefits of prewarmed infusion in elderly patients who underwent bilateral hip replacement. Methods: Between September 2015 and April 2016, elderly patients who underwent bilateral hips replacement that met the inclusion and exclusion criteria were included in this study. After inclusion, patients were randomized into one of the study groups: in the control group, patients received an infusion of fluid kept at room temperature (22–23°C); in the warming infusion group, patients received an infusion of fluid warmed using an infusion fluid heating apparatus (35°C). Postoperative outcomes, including recovery time, length of hospital stay, visual analogue scale (VAS) score, and postoperative complications rate of patients from both groups, were compared. Results: A total of 64 patients were included in our study (71.2 ± 7.6 years, 53.1% males), with 32 patients in the control group and 32 patients in warming infusion group. No significant difference was found in terms of demographic data and intraoperative blood transfusion rate between 2 groups (P > 0.05). Patients receiving a prewarmed infusion had a significantly shorter time to spontaneous breath, eye opening, consciousness recovery, and extubation than the control group (P < 0.05). In addition, significant differences were found in Steward score and VAS score between 2 groups (P < 0.05). Moreover, warming infusion group also showed an obviously decreased incidence of shivering and postoperative cognitive dysfunction (P < 0.05). Conclusion: A prewarmed infusion could reduce the incidence of perioperative hypothermia and improve outcomes in the elderly during bilateral hip replacement. PMID:28353593

    Abstract Despite exhaustive efforts to detect early-stage ovarian cancers, greater than two-thirds of patients are diagnosed at an advanced stage. Although diaphragmatic metastasis is not rare in advanced ovarian cancer patients and often precludes optimal cytoreductive surgery, little is known about the mechanisms and predictive factors of metastasis to the diaphragm. Thus, as an initial step toward investigating such factors, the present study was conducted to characterize the pathological status of ovarian cancer patients who underwent debulking surgery in combination with diaphragmatic surgery. This is a retrospective and cross-sectional study of patients who underwent debulking surgery in combination with diaphragmatic surgery at our institution between January 2005 and July 2015. Clinicopathological data were reviewed by board-certified gynecologists, pathologists, and cytopathologists. The rates of various pathological findings were investigated and compared by Fisher exact test between 2 groups: 1 group that was pathologically positive for diaphragmatic metastasis (group A) and another group that was pathologically negative for diaphragmatic metastasis (group B). Forty-six patients were included: 41 patients pathologically positive and 5 pathologically negative for diaphragmatic metastasis. The rates of metastasis to the lymph node (95.8% vs 20%, P = 0.001) and metastasis to the peritoneum except for the diaphragm (97.6% vs 60.0%, P = 0.028) were significantly increased in group A compared with group B. However, no significant differences between the 2 groups were found for rates of histological subtypes (high-grade serous or non-high-grade serous), the presence of ascites, the presence of malignant ascites, exposure of cancer cells on the ovarian surface, blood vascular invasion in the primary lesion, and lymphovascular invasion in the primary lesion. Our study demonstrated that metastasis to the lymph node and nondiaphragmatic metastasis to the

    For normal eyes without history of any ocular surgery, traditional equations for calculating intraocular lens (IOL) power, such as SRK-T, Holladay, Higis, SRK-II, et al., all were relativley accurate. However, for eyes underwent refractive surgeries, such as LASIK, or eyes diagnosed as keratoconus, these equations may cause significant postoperative refractive error, which may cause poor satisfaction after cataract surgery. Although some methods have been carried out to solve this problem, such as Hagis-L equation[1], or using preoperative data (data before LASIK) to estimate K value[2], no precise equations were available for these eyes. Here, we introduced a novel intraocular lens power estimation method by accurate ray tracing with optical design software ZEMAX. Instead of using traditional regression formula, we adopted the exact measured corneal elevation distribution, central corneal thickness, anterior chamber depth, axial length, and estimated effective lens plane as the input parameters. The calculation of intraocular lens power for a patient with keratoconus and another LASIK postoperative patient met very well with their visual capacity after cataract surgery.

    Objective Postoperative vomiting (POV) is one of the most common problems following general anaesthesia, and many factors, either solely or in combination, may play a role in aetiology. Acupuncture is a technique that the World Health Organization has accepted as a complementary treatment. This study presents our experience with acupuncture for POV treatment in a study of paediatric tonsillectomy cases. Methods The study included ASA I–II patients (n=70) aged 2–14 years who underwent tonsillectomy and/or adenoidectomy under general anaesthesia. The patients were randomly divided into the following two groups: control and study group. In the study group, an acupuncture needle was intraoperatively applied to the P6 acupuncture point for 20 min. Antiemetics were not administered to either group because of the standard applications in the preoperative period. The patients were postoperatively evaluated by nurses who were unaware about the techniques used in either group. Results No statistically significant difference was determined between the groups with regard to age, sex, nature of the operation, duration of anaesthesia, duration of the operation, surgical method and ASA scores. A statistically significant difference was determined between the groups with respect to vomiting rates. The acupuncture group presented with 0.28-times fewer vomiting episodes than the control group. Conclusion The results of the study demonstrate that acupuncture has an apparent antiemetic efficacy in POV. Its routine use for POV may improve postoperative comfort and reduce drug use for prophylactic or therapeutic purposes. PMID:27366548

    Extramedullary disease (EMD), defined as an infiltrate of clonal plasma cells at an anatomic site distant from the bone marrow, is an uncommon manifestation of multiple myeloma. Six hundred and sixty-three consecutive patients with multiple myeloma who underwent stem cell transplantation between January 2005 and December 2011 were assessed for the presence of EMD. A cohort of 55 patients with biopsy-proven EMD was identified, comprising 8·3% of the total study population. EMD was present at the time of diagnosis in 14·5% of cases and at the time of relapse in 76% of patients. The most common EMD presentations at relapse were liver involvement and pleural effusions. EMD specimens had high expression of CD44 (92%) and moderate expression of CXCR4. The median overall survival from time of myeloma diagnosis was 4·1 years (95% CI: 3·1, 5·1) and the median overall survival from time of EMD diagnosis was 1·3 years (95% CI: 0·8, 2·3). This report demonstrates that the incidence of EMD has not increased with the introduction of novel agents and stem cell transplantation. The most common EMD presentations in the relapsed setting were liver and pleural fluid. The presence of CD44 and CXCR4 expression may represent new markers of EMD that warrant further investigation.

    The first of three X-43A hypersonic research aircraft and its modified Pegasus booster rocket recently underwent combined systems testing while mounted to NASA's NB-52B carrier aircraft at the Dryden Flight Research Center, Edwards, Calif. The combined systems test was one of the last major milestones in the Hyper-X research program before the first X-43A flight. The X-43A flights will be the first actual flight tests of an aircraft powered by a revolutionary supersonic-combustion ramjet ('scramjet') engine capable of operating at hypersonic speeds (above Mach 5, or five times the speed of sound). The 12-foot, unpiloted research vehicle was developed and built by MicroCraft Inc., Tullahoma, Tenn., under NASA contract. The booster was built by Orbital Sciences Corp., Dulles, Va.,After being air-launched from NASA's venerable NB-52 mothership, the booster will accelerate the X-43A to test speed and altitude. The X-43A will then separate from the rocket and fly a pre-programmed trajectory, conducting aerodynamic and propulsion experiments until it descends into the Pacific Ocean. Three research flights are planned, two at Mach 7 and one at Mach 10.

    Archaeological and genetic evidence concerning the time and mode of wild horse (Equus ferus) domestication is still debated. High levels of genetic diversity in horse mtDNA have been detected when analyzing the control region; recurrent mutations, however, tend to blur the structure of the phylogenetic tree. Here, we brought the horse mtDNA phylogeny to the highest level of molecular resolution by analyzing 83 mitochondrial genomes from modern horses across Asia, Europe, the Middle East, and the Americas. Our data reveal 18 major haplogroups (A–R) with radiation times that are mostly confined to the Neolithic and later periods and place the root of the phylogeny corresponding to the Ancestral Mare Mitogenome at ∼130–160 thousand years ago. All haplogroups were detected in modern horses from Asia, but F was only found in E. przewalskii—the only remaining wild horse. Therefore, a wide range of matrilineal lineages from the extinct E. ferus underwent domestication in the Eurasian steppes during the Eneolithic period and were transmitted to modern E. caballus breeds. Importantly, now that the major horse haplogroups have been defined, each with diagnostic mutational motifs (in both the coding and control regions), these haplotypes could be easily used to (i) classify well-preserved ancient remains, (ii) (re)assess the haplogroup variation of modern breeds, including Thoroughbreds, and (iii) evaluate the possible role of mtDNA backgrounds in racehorse performance.

    PTP1B is involved in the oncogenesis of breast cancer. In addition, neoadjuvant therapy has been widely used in breast cancer; thus, a measurement to assess survival improvement could be pathological complete response (pCR). Our objective was to associate PTP1B overexpression with outcomes of breast cancer patients who underwent neoadjuvant chemotherapy. Forty-six specimens were included. Diagnostic biopsies were immunostained using anti-PTP1B antibody. Expression was categorized as negative (<5%) and overexpression (≥5%). Patients’ responses were graded according to the Miller–Payne system. Sixty-three percent of patients overexpressed PTP1B. There was no significant association between PTP1B overexpression and pCR (P = 0.2). However, when associated with intrinsic subtypes, overexpression was higher in human epidermal growth factor receptor 2-positive-enriched specimens (P = 0.02). Ten-year progression-free survival showed no differences. Our preliminary results do not show an association between PTP1B over-expression and pCR; however, given the limited sample and heterogeneous treatment in our cohort, this hypothesis cannot be excluded.

    Background Transcatheter aortic valve implantation (TAVI) is a new treatment option for patients with severe aortic stenosis. Pre-TAVI procedure workup includes computed tomography angiography (CTA) of the heart and aorta from aortic annulus to the iliofemoral arteries. Frequently, there are a number of incidental non-cardiac findings (INCFs) in pre-TAVI CTA. However, the frequency and clinical significance of these INCFs are unknown. The aim of our study was to investigate the prevalence of INCFs and their clinical significance. Methods This was a retrospective review of 67 patients who underwent dedicated pre-TAVI CTA from 2010 till 2015. Non-cardiovascular INCFs were classified according to their clinical significance into three categories. The first category includes findings that may require urgent treatment. The second category includes findings that need further follow-up. The third category includes incidental findings that require no further follow-up or recommendation. Results The total number of patients was 67, and the mean age was 73 ± 8 years. All patients had INCFs and the total number was 248. Of the patients, 69% had chest findings, 85% had abdominal findings, and 33% had musculoskeletal findings. Results based on categorical classification were as follows: 9%, 25%, and 66% of these 248 findings belong to the first category, the second category, and the third category, respectively. Conclusion Non-cardiovascular INCFs are common in pre-TAVI CTA presumably due to increased age of such specific population. These findings have variable clinical significance and some of them might require acute treatment or additional evaluation, and should be managed properly taking into consideration patient’s life expectancy and comorbidities.

    Objective Possible reasons for hysterectomy in the initial surgical management of advanced invasive epithelial ovarian carcinoma (EOC) might be a high frequency of uterine involvement and its impact on survival. The aim of the present study was to describe the frequency of uterine involvement and its association with survival in an unselected population of EOC patients who underwent hysterectomy. Methods All incident cases of EOC diagnosed in Israeli Jewish women between March 1994 to June 1999, were identified within the framework of a nationwide case-control epidemiological study. The target population of the present report includes all stage II-IV EOC patients who had a uterus at the time of diagnosis. Of the 822 such patients, 695 fulfilled the inclusion criterion. Excluded were 141 patients for various reasons. The present analysis is based on the remaining 554 patients. Results Uterine involvement was present in 291 (52.5%) of the patients and it was macroscopic in only 78 (14.1%). The serosa was the most common site of isolated metastases. Multivariate analysis showed that advanced stage significantly increased the risk for uterine involvement. The overall median survival with any uterine involvement was significantly lower compared to those with no involvement (38.9 months vs. 58.0 months; p<0.001). Conclusion There is an association between uterine involvement, whether macro- or microscopic, and lower survival even after hysterectomy although residual tumor could not be included in the analysis. Further studies are required to establish whether uterine involvement itself is an unfavorable risk factor or merely a marker of other unfavorable prognostic factors. PMID:20922143

    We investigated the effects of lateral osteotomy on nasal sound intensity levels in 34 patients who underwent rhinoplasty. Four groups were evaluated: group 1, preoperative rhinoplasty with lateral osteotomy (Preop-RPwithLO); group 2, postoperative rhinoplasty with lateral osteotomy (Postop-RPwithLO); group 3, preoperative rhinoplasty without lateral osteotomy (Preop-RPwithoutLO); and group 4, postoperative rhinoplasty without lateral osteotomy (Postop-RPwithoutLO). By sound analysis, low-frequency (Lf; 500-1000 Hz), medium-frequency (Mf; 1-2 kHz), and high-frequency (Hf; 2-4 and 4-6 kHz) nasal sound intensities were defined. Mf-left values of Postop-RPwithLO were significantly lower than those of Preop-RPwithLO, and Mf-left values of Postop-RPwithoutLO were significantly higher than those of Postop-RPwithLO and Preop-RPwithoutLO. Hf-right values of Preop-RPwithoutLO were significantly higher than those of Postop-RPwithLO and Postop-RPwithoutLO. Hf-total values of Postop-RPwithoutLO were significantly lower than those of Preop-RPwithoutLO. Nasal airway width decreased and nasal sounds, especially Mf sound intensities, increased in the nonlateral osteotomy group (group 4). When lateral osteotomy is performed, the nasal air passage may be adjusted as required by the surgeon, the air passage in the nasal valve region may not be narrowed, and nasal sound intensities may decrease. During postoperative follow-ups, increased Mf and Lf nasal sound intensities should be considered for the narrowness of the nasal passage and lower patency of the nasal cavities. Nasal sound analysis is a noninvasive technique and can also be used to evaluate nasal patency in septoplasty and rhinoplasty patients and children and for cases in which official reports are needed in addition to acoustic rhinometry measurements.

    unexplained etiology differ from healthy and fertile women. These differences are mainly connected to the humoral immunity and manifested in absence of blocking antibodies in sera of women with RSA and in frequent occurrence of antinuclear and anticardiolipin antibodies. Among autoantibodies, only ACA at medium and high levels are the ones that can negatively influence on the pregnancy outcome in women with RSA who underwent paternal lymphocytes immunization. The clinical classification of women with RSA into primary and the secondary aborters is reflected neither in immunological results nor in efficacy of paternal lymphocytes immunization.

    Fewer than 20 patients with lymphocytic adenohypophysitis have been reported, all of them women, and it usually occurs during pregnancy or the postpartum period. We report the recognition of lymphocytic adenohypophysitis in a man. The patient presented with anterior hypopituitarism and an intrasellar mass on computed tomography. Antipituitary antibodies, found in only one of the previous patients, were not present in this man, although low titer antinuclear antibodies were found. The implications of this latter finding are unclear. The patient's histocompatibility antigen (HLA) types were A2, B8, Bw58, DR1, and DR5. The degree of pituitary failure seemed out of proportion to the size of the mass seen on computed tomographic scan.

    The two worlds of interactive graphics and realistic graphics have remained separate. Fast graphics hardware runs simple algorithms and generates simple looking images. Photorealistic image synthesis software runs slowly on large expensive computers. The time has come for these two branches of computer graphics to merge. The speed and expense of graphics hardware is no longer the barrier to the wide acceptance of photorealism. There is every reason to believe that high quality image synthesis will become a standard capability of every graphics machine, from superworkstation to personal computer. The significant barrier has been the lack of a common language, an agreed-upon set of terms and conditions, for 3-D modeling systems to talk to 3-D rendering systems for computing an accurate rendition of that scene. Pixar has introduced RenderMan to serve as that common language. RenderMan, specifically the extensibility it offers in shading calculations, is discussed.

The capabilities of the interactive software package being presently developed by the SRS for the mission/program analysis are described, and it is shown that the interactive package can be used to investigate the impact of various mission concepts on the sensitivity of mass required in LEO, schedules, relative costs, and risk. The results, to date, indicate the need for an earth-to-orbit transportation system much larger than the present STS, reliable long-life support systems, and either advanced propulsion or aerobraking technology.

    As the population is ageing globally, both ageing and obesity are recognized as major public health challenges. The aim of this narrative review is to present and discuss the current evidence on the changes in body composition, energy balance and endocrine environment that occur in the ageing man. Obesity in the ageing man is related to changes in both body weight and composition due to alterations in energy intake and total energy expenditure. In addition, somatopenia (decreased GH secretion), late-onset hypogonadism (LOH), changes in thyroid and adrenal function, as well as changes in appetite-related peptides (leptin, ghrelin) and, most importantly, insulin action are related to obesity, abnormal energy balance, redistribution of the adipose tissue and sarcopenia (decreased muscle mass). A better understanding of the complex relationship of ageing-related endocrine changes and obesity could lead to more effective interventions for elderly men.

    The quantity of online documentation and viewing tools is overwhelming, with the World Wide Web, vendor-supported and local-site documentation and tools, etc. Maintaining the information and tools is equally overwhelming. However, statistics show that MAN usage far exceeds usage of other online documentation tools. But as one knows, MAN has its own problems, and at the forefront are MAN`S many inconsistencies. MAN is the standard Unix (and POSIX) tool which provides good summary information for those already familiar with a command. Well-written manual pages provide a good overall documentation. However, when a particular manual becomes too long, it becomes a cumbersome method to use for reading documentation.

    1980-01-01

    The astronaut/Manned Maneuvering Unit interface, which presented a challenging set of requirements for a latching mechanism, is described. A spring loaded cam segment with variable ratio pulley release actuator was developed to meet the requirements. To preclude jamming of the mechanism, special precautions were taken such as spring loaded bearing points and careful selection of materials to resist cold welding. The mechanism successfully passed a number of tests which partially simulated orbital conditions.

  17. Multiple man-machine interfaces

    Stanton, L.; Cook, C. W.

    1981-01-01

    The multiple man machine interfaces inherent in military pilot training, their social implications, and the issue of possible negative feedback were explored. Modern technology has produced machines which can see, hear, and touch with greater accuracy and precision than human beings. Consequently, the military pilot is more a systems manager, often doing battle against a target he never sees. It is concluded that unquantifiable human activity requires motivation that is not intrinsic in a machine.

    Nine reports published in this volume study the uneasy coexistence of modern man and the complex society he has wrought. Man's apparent disorganized behavior is attributed to his inability to adapt readily to the charged pace of technological change. To combat the advancement of machine over man, he must, therefore, insist that moral and…

    1983-01-01

    Human capabilities and requirements on space missions are discussed. Utilitarian and humanistic motivations for manned missions are considered, and a general program of development from easy space access and return, to a permanent LEO presence, to the limited self-sufficiency of man in space, is proposed. Man's potential as scientific observer, operator, and engineer/technician is illustrated with examples from the Apollo and Skylab missions. It is shown that future increases in man's space presence will require significant improvements in habitation technology, crew comfort and safety, operational effectiveness and reliability, and man/machine interactions: man-tended systems must be standardized and adapted to (mainly EVA) human servicing; permanently manned systems must be designed to attain levels of comfort, privacy, and overall habitability more like those expected on the ground.

    1973-01-01

    The program for the Apollo 16 flight was designed to include both safeguards against and investigations of the physiological problems arising from increase in the period of manned space flight. Precautions included the provision of a controlled diet with high potassium content, carefully controlled work loads and work-rest cycles, and an emergency cardiology consultation service, and investigations were made to enable preflight vs postflight comparisons of metabolic, cardiovascular, and central nervous system data. Results of these investigations indicate that adjustment to weightlessness can be satisfactorily assisted by appropriate countermeasures, including attention to diet.

    Fibrodysplasia ossificans progressiva (FOP) is a rare hereditary connective tissue disease characterized by the progressive ectopic ossification of ligaments, tendons, and facial and skeletal muscles throughout life. Symptoms begin in childhood as localized soft tissue swellings. Immobility and articular dysfunction appear with involvement of the spine and proximal extremities. The temporomandibular joint (TMJ) is a critical component involved in the maxillofacial region, resulting in severe limitation of masticatory function, although TMJ involvement is rare. The aim of this article is to present a 28-year-old man with dental problems and slowly progressive limitation of motion in the jaw, knees, shoulders and hips as well as neck distortion.

  8. The rights of man and animal experimentation.

    PubMed

    Martin, J

    1990-09-01

    Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analogy. However, cruelty to animals is illicit and they should be protected, principally not because they have rights, but because he who is cruel to animals is more likely to be cruel to his fellowman. If there is a need for animal experimentation in science for the good of man, this approach gives philosophical justification for experimentation, since man's well-being must come before that of animals because of his unique possession of rights. However, those experiments should be carried out in the kindest way possible, to promote kindness towards man. To see man as solely part of a biological continuum in competition for rights with those beings close to him biologically, detracts from man's dignity.

  9. The Socio-Technical Man

    Moreno, Yamir

    In the last 20 years or so, the field of complexity science has entered a new age. The combination of new theoretical insights and the data revolution has prepared the ground for a number of conceptual milestones in many disciplines as diverse as biology, physics, engineering, and economic and social sciences. At the same time, we have been able to identify new challenges whose solutions will confer the science of complex systems an unprecedented applied dimension. Here I would like to focus on one of these challenges: the socio-technical man. With the ever-increasing growth of both the world population and new technologies, it is fundamental for the well-being of humanity and our society to understand how humans interact among them and with the new technological environment...

    Three male swimmers underwent 10-min resting and 20-min swimming (breaststroke) exposures in a swimming flume. Water temperatures in separate exposures were 18, 26, and 33 C. At each water temperature the subjects rested and swam at water velocities of 0.50, 0.75, and 0.95 m/sec, which were designed to produce around 40, 70, and 100% of maximal aerobic power. Measurements were made of esophageal temperature, four skin temperatures, water temperature, heat flow from five local skin surfaces (Hatfield-Turner disks), and oxygen uptake. Calculations were made of mean area-weighted skin temperature and heat flow, metabolic rate, and heat storage. Internal body temperature changes after 20 min of swimming were related to water temperature, swimming intensity, and body composition.

    A 68-year-old man underwent total cystectomy, urethrectomy preserving fossa navicularis, and an Indiana pouch urinary diversion in 1997. The histopathology was UC, G3, pT4 (prostate). Nine years after the operation, he had multiple metastases to the inguinal and paraaortic lymph nodes (LNs), and he complained of erosion around the glans. Histological diagnosis of the glans revealed recurrent UC to the urethra of the glans. We considered the possibility that the inguinal LN metastasis was due to lymphatic spread from a remnant urethral recurrence. Thus, a partial penectomy and inguinal LN dissection were undertaken. Systemic chemotherapy was administered. Remnant urethral recurrence after urethrectomy preserving the fossa navicularis and inguinal LN metastasis are rare.

    A 68-year-old man underwent an inguinal orchiectomy for a right testicular tumor and the pathological diagnosis was atypical lipomatous tumor. Nine years later, a resection procedure was performed for local recurrence. Five years after that second surgery, abdominal computed tomography (CT) findings revealed a low density mass 40 mm in size on the back side of the right kidney and enlarged fat in the retroperitoneal space. We performed a laparoscopic tumor resection under a diagnosis of lipoma or liposarcoma recurrence, and the pathological diagnosis was well differentiated liposarcoma. Treatment with pazopanib was started, as a CT examination showed that the tumor remained, after which we performed an open nephroureterectomy and resected the remaining tumor portion. Pazopanib treatment was continued and no obvious signs of recurrence were seen at 8 months after the most recent surgery. Although well differentiated liposarcoma usually recurs in the original tumor region, multicentric recurrence in other parts is possible.

  14. Scintigraphic Evidence for Overdiagnosis of Small PE on CT Pulmonary Angiography.

    2017-03-01

    A 68-year-old man with recent history of a fall presented with dyspnea on exertion, and underwent computed tomography pulmonary angiography (CTPA) for possible pulmonary embolism (PE). The CTPA was first read by the radiology resident as nondiagnostic for segmental PE. Subsequent planar perfusion (Q) images were normal; meanwhile, the attending radiologist revised the CTPA results as subsegmental PE in the left upper lobe. Further Q-SPECT images were obtained and fused with CTPA for clarification, which showed normal perfusion in the region of PE. The patient was monitored without anticoagulation treatment and remained uneventful for 12 months. This case illustrates that CTPA can lead to overdiagnosis and overtreatment of nonocclusive subsegmental PE.

    2013-01-01

    Aortic prosthesis replacements including extra-anatomical bypass procedures, in situ revascularisations with the neoaortoiliac system, antibiotic bounded prostheses or allogeneic grafts have high graft reinfection rates. We described a case of a 68-year-old man with Samson group V Staphylococcus aureus infection of his aortobifemoral graft. He underwent an explantation of the infected graft, wound debridement and a hybrid in situ allogeneic aortoiliofemoral replacement. During surgery one of the limbs of the cryopreserved human aortic allogeneic graft was anastomosed with the endarterectomised left common iliac artery, which later was angioplastied and stented. The closed system Jackson-Pratt drains were used to prevent perigraft fluid collection. The groin wound was treated with the vacuum-assisted closure dressing. On review in 6 months he remained symptom free. We conclude that a hybrid management of infected aortic prosthesis may reduce graft reinfection. PMID:23897382

    Pulmonary blastoma is a very rare malignant tumor of the lungs. A biphasic pulmonary blastoma was histologically diagnosed by a characteristic finding as it was mainly constituted of immature tumor tissue that had both epithelial and mesenchymal components. We present a case of a 68-year-old man with biphasic pulmonary blastoma. The patient underwent cranial metastatectomy and left lung upper lobectomy. Although the tumor was resected, there was rapid metastasis to the cranial, liver, kidney and multiple bones. Although radiotherapy and chemotherapy were administrated, the patient died about 6 months postoperatively. Close follow-up and aggressive chemotherapy should be considered for such tumours. In the light of this case, the authors review the pathologic, clinical, radiological and therapeutic features of this very rare malignant lung tumor.

    Only a few studies have revealed using laparoscopic technique with limited resection of gastrointestinal stromal tumour (GIST) of the duodenum. A 68-year-old man was admitted to the hospital due to upper gastrointestinal (GI) bleeding. Evaluation revealed an ulcerated, bleeding GI tumour in the second part of the duodenum. After control of bleeding during gastroduodenoscopy, he underwent a laparoscopic wedge resection of the area. During 1.5 years of follow-up, the patient is disease free, eats drinks well, and has regained weight. Surgical resection of duodenal GIST with free margins is the main treatment of this tumour. Various surgical treatment options have been reported. Laparoscopic resection of duodenal GIST is an advanced and challenging procedure requiring experience and good surgical technique. The laparoscopic limited resection of duodenal GIST is feasible and safe, reducing postoperative morbidity without compromising oncologic results. PMID:28281485

    He was sitting on a large slab of rock. As he looked at the cloud of dust hanging hazily on the horizon, the piece of antler and the block of flint he held in his hand hung as if they were suspended from their previous rapid motion. The man gazed intently across the swaying grass which rose in wave-like billows across the distant hills. What was that dust - a herd of buffalo, a band of hunters, or were coyotes chasing the antelope again? After watching for a while he started again to chip the flint with a rapid twisting motion of the bone in his right hand. The little chips of flint fell in the grass before him. It is the same hill but the scene has changed. Seated on the same rock, holding the reins of a saddle horse, a man dressed in buckskin took the fur cap off his head and wiped his brow. He was looking intently across a brown and desolate landscape at a cloud of dust on the far horizon. Was it the hostile tribe of Indians? It could be buffalo. Nervously he kicked at the ground with the deerhide moccasin, pushing the flint chips out of the way. He wiped the dust from his long rifle. What a terrible place - no water, practically no grass, everything bare and brown. Now at sunset, slanting across the hills green with springtime, a cowman sits on a big rock, pushes his sombrero back on his head, and looks across the valley at a large but quiet herd of stock, moving slowly as each steer walks from one lush patch of grass to another, nibbling. Suddenly he stood up. Far on the horizon some dark objects were moving. Is it the sheepmen? Could it be the stage coach from Baggs to the Sweetwater Crossing?Same hill - a gray truck was grinding slowly toward the summit. It pulled up near a small fenced enclosure where there were some instruments painted a bright silver color. A man stepped out of the truck and turned to his younger companion, "You've never found an arrowhead? Maybe you have never thought about it correctly. If you want to find where an Indian camped long

    This study describes the peroperative endoscopic findings about the size, shape and mucosal changes of the middle turbinate in patients with chronic sinusitis who underwent total spheno-ethmoidectomy. Results confirmed the middle turbinate to be a useful landmark in performing extensive sinus surgery. The most frequent change due to chronic inflammation seems to be polypous degeneration followed by hyperplastic mucosa. Anatomical variations, being paradoxically bent turbinate and concha bullosa, are not seen frequently.

    Total hip replacement (THR) and total knee arthroplasty (TKA) carry a high risk of postoperative venous thromboembolism (VTE); therefore, anticoagulation prophylaxis is recommended in these patients. Unfortunately, there are no guidelines about VTE prophylaxis in patients with hemophilia who underwent these high-risk surgeries. To determine whether these patients have high risk of VTE, we conducted a retrospective study on patients with hemophilia who underwent elective THR/TKA at our institute from 2004 to 2012. Postoperatively, we collected information on duration and method of factor VIII/IX infusion, VTE-prophylaxis, and complications. There were 23 patients with hemophilia, 18 (78%) with hemophilia A and 5 (22%) with hemophilia B, who underwent high-risk surgeries (39% THR and 61% TKA). The VTE prophylaxis included sequential compression device, 12 (52%), and prophylactic enoxaparin, 1 (4%). Ten (43%) patients did not receive VTE prophylaxis. At 1-year follow-up, we did not find any evidence of clinical VTE in our patients. Better risk stratification is needed to identify patients who would benefit from pharmacological prophylaxis.

    The universe has always aroused people's curiosity. It fascinates and at the same time scares in its vastness. Encourages us to reflect of the meaning of human life. This begs the questions: whether there is a life beyond Earth? Whether is it possible that the man is alone in such a large space? These questions still remain unanswered, and topics concerning "the cosmos" constantly evoke many emotions. It is especially fascinating for the youngest students. Quite often, preschoolers can flawlessly name the planets according to their order of appearance in relation to the sun. They are happy to take the fun inspired by journeys into space. Teaching through action is extremely important for the development of the child-man* (Piaget, 2006). The thinking originates primarily from the action. Therefore, students should undertake independent research activities, perform experiments and conduct observations and thus raise questions about the world, looking for meanings and solutions. Adults (a teacher, a person with a passion) are to be the support in the search for knowledge, its processing and cleaning. Its role is to ensure a proper development of environment that is conducive to research activity. The answer to these requirements was to create in the oldest technical school in Poland (Railway Technical College, now Technical College No. 7) the astronomical observatory, which can be used by pupils of Warsaw's kindergartens and schools. There are organized activities for children and youth in this school, as well as trainings for teachers. Younger students during such an interdisciplinary courses are, among others, the opportunity to get acquainted with the construction of the telescope, they can build their own rockets and organize their racing or create your own star constellations. Older students as a result of observations and experiments may confirm or refute the hypothesis that the universe is within each of us. The classes are enriched using applications on

    Man's ability to live and perform useful work in space was demonstrated throughout the history of manned space flight. Current planning envisions a multi-functional space station. Man's unique abilities to respond to the unforeseen and to operate at a level of complexity exceeding any reasonable amount of previous planning distinguish him from present day machines. His limitations, however, include his inherent inability to survive without protection, his limited strength, and his propensity to make mistakes when performing repetitive and monotonous tasks. By contrast, an automated system does routine and delicate tasks, exerts force smoothly and precisely, stores, and recalls large amounts of data, and performs deductive reasoning while maintaining a relative insensitivity to the environment. The establishment of a permanent presence of man in space demands that man and machines be appropriately combined in spaceborne systems. To achieve this optimal combination, research is needed in such diverse fields as artificial intelligence, robotics, behavioral psychology, economics, and human factors engineering.

    A brief history of the development of electrical power systems from the earliest manned space flights illustrates a natural trend toward a growth of electrical power requirements and operational lifetimes with each succeeding space program. A review of the design philosophy and development experience associated with the Space Shuttle Orbiter electrical power system is presented, beginning with the state of technology at the conclusion of the Apollo Program. A discussion of prototype, verification, and qualification hardware is included, and several design improvements following the first Orbiter flight are described. The problems encountered, the scientific and engineering approaches used to meet the technological challenges, and the results obtained are stressed. Major technology barriers and their solutions are discussed, and a brief Orbiter flight experience summary of early Space Shuttle missions is included. A description of projected Space Station power requirements and candidate system concepts which could satisfy these anticipated needs is presented. Significant challenges different from Space Shuttle, innovative concepts and ideas, and station growth considerations are discussed. The Phase B Advanced Development hardware program is summarized and a status of Phase B preliminary tradeoff studies is presented.

  19. Hermes - A manned European system

    NASA Astrophysics Data System (ADS)

    Cretenet, J.-C.

    Features of a European hypersonic winged reentry vehicle, Hermes, are presented, together with the technology requirements for its development and the missions it would serve. LEO is beginning to hold promise for the manufacture of materials in microgravity and/or vacuum conditions in orbiting facilities which need to be serviced. A manned, reusable, winged reentry vehicle would permit the delivery and return of payloads from space, recovery of the first stage of the Ariane V rocket for reuse, and return of the Hermes to a landing at the Kourou launch site. The avionics would be similar to those of modern aircraft, as would the landing system. In-orbit operational techniques would be needed, as would an internal environment similar to Spacelab, a rigid turnaround time, high utilization rate, and a 10 yr lifetime. The length of the Hermes is projected as 12.5 m, wingtip to wingtip breadth of 7.4 m, and a total mass of 11,400 kg for a heliosynchronous orbit mission, while 15,400 kg are available for a circular, 490 m/sec orbit.

    Background: Female genital malformations represent miscellaneous deviations from normal anatomy. This study aimed to explore the clinical characteristics of patients who underwent surgery for genital tract malformations at Peking Union Medical College Hospital (PUMCH) during a 31-year period. Methods: We retrospectively reviewed surgical cases of congenital malformation of the female genital tract at PUMCH for a 31-year period, analyzed the clinical characteristics of 1634 hospitalized patients, and investigated their general condition, diagnosis, and treatment process. Results: The average patient age was 27.6 ± 9.9 years. The average ages of patients who underwent surgery for uterine malformation and vaginal malformation were 31.9 ± 8.8 years and 24.7 ± 9.0 years, respectively; these ages differed significantly (P < 0.01). Among patients with genital tract malformation, the percentages of vaginal malformation, uterine malformation, vulva malformation, cervical malformation, and other malformations were 43.9%, 43.5%, 7.4%, 2.3%, and 2.8%, respectively. Among patients with uterine malformation, 34.5% underwent surgery for the genital tract malformation, whereas in patients with vaginal malformation, the proportion is 70.6%; the difference between the two groups was statistically significant (P < 0.01). The percentage of complications of the urinary system in patients with vaginal malformations was 10.2%, which was statistically significantly higher than that (5.3%) in patients with uterine malformations (P < 0.01). Conclusions: Compared to patients with uterine malformations, patients with vaginal malformations displayed more severe clinical symptoms, a younger surgical age, and a greater need for attention, early diagnosis, and treatment. Patients with genital tract malformations, particularly vaginal malformations, tend to have more complications of the urinary system and other malformations than patients with uterine malformations.

    Abstract A retrospective analysis was conducted to investigate outcomes of elderly patients with resectable esophageal squamous cell carcinoma (ESCC) who underwent surgery or chemoradiotherapy (CRT). We performed a retrospective review of the records of elderly patients (≥70 years) with resectable ESCC who underwent esophagectomy or CRT between January 2009 and March 2013. According to the main treatment strategy, patients were allocated into either surgery group or CRT group. Overall survival (OS), cancer-specific survival and progression-free survival were calculated by the Kaplan–Meier method. Univariate and multivariate survival analyses were performed by the Kaplan–Meier method and Cox proportional hazards model, respectively. A total of 188 patients were enrolled. Eighty-eight patients underwent esophagectomy, and 100 patients underwent CRT. The median age of the patients was 73 years (range, 70–81 years) in the surgery group and 76 years (range, 70–88 years) in the CRT group. The median survival time (MST) for the whole cohort was 25.6 months, and 1-, 3-, and 5-year survival rates were 69.2%, 36.1%, and 21.9%, respectively. The MST in the surgery group and the CRT group was 36 months and 15 months, respectively. The 1-, 3-, and 5-year survival rates in the surgery group were 82.4%, 49.0%, and 33.3%, compared to 58.0%, 24.1%, and 7.8% in the CRT group (P < 0.0001). Multivariate analysis revealed that lymph node status (hazard ratio [HR] = 0.598, P = 0.011) and treatment strategies (HR = 0.538, P = 0.001) were independent and significant prognostic factors for OS in elderly patients. Surgery was the main treatment strategy for elderly patients with ESCC. Advanced age and comorbidities should not be the cause for elderly patients to avoid aggressive regimens. Delivered therapeutic approaches should be individualized on the basis of carefully evaluating the balance of benefits, risks, and life expectancy. PMID:27977606

    Systolic anterior motion (SAM) of the mitral apparatus is a relatively frequent complication of mitral valve repair. When significant SAM persists despite intraoperative medical therapies, a second repair is generally required. We describe a rare case of SAM due to a hypertrophic septum in a patient who underwent mitral valve repair, with no preoperative obstruction of the left ventricular outflow tract. The present case of SAM was successfully treated only with transaortic septal myectomy. Therefore, myectomy might be considered as an alternative solution for SAM that is suspected to be caused by a hypertrophic septum after mitral valve repair.

    As part of a propulsion/airframe integration program, tests were conducted in the Langley 16-Foot Transonic Tunnel to determine the longitudinal aerodynamic effects of installing flow through engine nacelles in the aft underwing position of a high wing transonic transfer airplane. Mixed flow nacelles with circular and D-shaped inlets were tested at free stream Mach numbers from 0.70 to 0.85 and angles of attack from -2.5 deg to 4.0 deg. The aerodynamic effects of installing antishock bodies on the wing and nacelle upper surfaces as a means of attaching and supporting nacelles in an extreme aft position were investigated.

    The lung is a common site of metastases, whose prevalence varies as a function of the primary tumor site, which is usually colorectal cancer (CRC), breast carcinoma, or genitourinary cancers, such as ovary, urinary bladder and renal cell carcinomas. The aim of the present study was to analyze whether the site of primitive tumor affects overall survival (OS) of patients with lung metastases (LMs) who underwent pulmonary metastasectomy. The data of 41 patients with surgically treated CRC (Group A=22 patients) and non-colorectal carcinomas (Group B=19 patients), who developed matachronous LMs and underwent pulmonary metastasectomy with curative intent, were analyzed. The origin of non-colorectal LMs was genitourinary cancer in nine and breast cancer in 10 patients. Overall, there were 22 men and 19 women, with a median age of 65 years (range=31-80); 18 patients had a solitary metastatic tumor, while 23 had two or more LMs. Twenty-nine patients underwent wedge resection, through thoracotomy or video-assisted thoracic surgery, while 12 underwent pulmonary lobectomy. Seventy-five LMs were resected with a 5-tear OS of 48.8%. No difference was found between elderly (≥65 year-old) and younger patients (p=0.26), and between those with solitary or multiple LMs (p=0.62) in terms of survival rate. The female patients had a worse OS (31.6% vs. 63.6%; odds ratio (OR)=3.79, 95% confidence interval (CI)=1.03-13.91, p=0.003) compared to males, independent of the origin of primary cancer. There was no difference in the cumulative survival rates (OR=1.65, 95%CI=0.48-5.69, p=0.42) between Groups and the log-rank test (p=0.75) was not significant. In conclusion, the main pathological characteristics of metastatic lesions and advanced age do not appear to be associated with a poor prognosis in patients with LMs, while the female gender is a negative prognostic factor. Thus, the primary tumor site should not be considered a major criterion in selecting patients for pulmonary

    Kennewick Man, referred to as the Ancient One by Native Americans, is a male human skeleton discovered in Washington state (USA) in 1996 and initially radiocarbon-dated to 8340–9200 calibrated years BP1. His population affinities have been the subject of scientific debate and legal controversy. Based on initial study of cranial morphology it was asserted that Kennewick Man was neither Native American nor closely related to the Claimant Plateau tribes of the Pacific Northwest, who claimed ancestral relationship and requested repatriation under the Native American Graves Protection and Repatriation Act (NAGPRA). The morphological analysis was important to judicial decisions that Kennewick Man was not Native American and that therefore NAGPRA did not apply. Instead of repatriation, additional studies of the remains were permitted2. Subsequent craniometric analysis affirmed Kennewick Man to be more closely related to circumpacific groups such as the Ainu and Polynesians than he is to modern Native Americans2. In order to resolve Kennewick Man’s ancestry and affiliations, we have sequenced his genome to ~1× coverage and compared it to worldwide genomic data including the Ainu and Polynesians. We find that Kennewick Man is closer to modern Native Americans than to any other population worldwide. Among the Native American groups for whom genome wide data is available for comparison, several appear to be descended from a population closely related to that of Kennewick Man, including the Confederated Tribes of the Colville Reservation (Colville), one of the five tribes claiming Kennewick Man. We revisit the cranial analyses and find that, as opposed to genomic-wide comparisons, it is not possible on that basis to affiliate Kennewick Man to specific contemporary groups. We therefore conclude based on genetic comparisons that Kennewick Man shows continuity with Native North Americans over at least the last eight millennia. PMID:26087396

    Introduction The role of the speech-language pathology in the multiprofessional team dealing with laryngology and the voice has been recognized for a long time. Scientific studies in this field recommend therapies for laryngeal microsurgeries; few of the studies, however, effectively evaluate the result of postoperative speech therapy. Objective To compare speech therapy evaluation and treatment among patients with phonotraumatic lesions and patients with lesions unrelated to phonotrauma who underwent laryngeal microsurgery. Methods This study was performed at IPO Hospital (Paranaense Institute of Otorhinolaryngology, Curitiba, Paraná, Brazil) between February 2010 and February 2011. Of 254 patients who underwent laryngeal microsurgery, 208 patients were included in the study and divided in two groups: group A with phonotraumatic lesions (n = 131) and group B with lesions unrelated to phonotrauma (n = 77). The number of sessions and the functional result after speech therapy were evaluated. Results The number of postoperative phonotherapy sessions after microsurgery was up to 10 sessions in 89.31% and 87.71% for groups A and B, respectively. Phonotherapy treatment showed a better functional evolution in group A (92.37%). Conclusion A significant difference was observed only in functional evolution, which was better in the group with phonotraumatic lesions (p < 0.0001). PMID:25992078

    A 2-year-and-4-month-old female infant, 12 kg in weight and 90 cm in height fell off from a table, which was about 1 m height with a toothbrush in her mouth without her parents noticing. Urgent CT scan showed that it penetrated the left side of her oropharyngeal wall to the bifurcation of her right carotid artery. According to the initial assessment, carotid artery seemed intact and there seemed to be no sign of CNS involvement. She underwent general anesthesia for further investigation and operation. We could detect vocal code with ease by inserting Glidescope between her tongue and the toothbrush. After the intubation, we administered fentanyl 25 μg rocuronium 15 mg and sevoflulane 3-5% to her, and then she underwent arteriography. The neurosurgeon found no sign of major arterial injury nor traumatic aneurysm nor CNS involvement. She went to the ICU intubated after the removal of the toothbrush. She was extubated 5 days after operation. One of the benefits of the Glidescope is that we can share the visual image, and we chose it this time. When we expect a difficult airway during management for oropharyngeal trauma, we have to consider the way to manage the airway.

    Antiplatelet agents are among the most important drug classes in reducing mortality in patients with acute coronary syndromes (ACS). Ticagrelor is the first reversible and direct acting P2Y(12) receptor inhibitor with an earlier onset of action compared to clopidogrel. The PLATO study (Platelet Inhibition and Patient Outcomes) with ticagrelor was conducted with a design providing consistency with the current clinical practice, including all forms of ACS and a wide spectrum of treatment options in 18624 patients from 862 centers in 43 countries. Of these patients, 13408 underwent interventional procedures (ticagrelor/clopidogrel; 6732/6676) (PLATO-INVASIVE). As reported by the investigator, non-invasive treatment strategy was planned for 5216 patients (ticagrelor/clopidogrel; 2601/2615). However, 2040 patients in this group received interventional treatment during the follow-up (PLATO-NON-INVASIVE/MEDICAL TREATMENT). 1261 patients requiring surgical treatment underwent coronary artery bypass grafting (CABG) within 7 days after the discontinuation of study treatment (ticagrelor/clopidogrel; 632/629) (PLATO-CABG). The results of these three subgroups were consistent with the main PLATO study results, demonstrating that ticagrelor reduced the primary (cardiovascular death, myocardial Infarction and stroke) and secondary composite endpoints without increasing bleeding compared with clopidogrel. Ticagrelor fulfills an important unmet need regarding antiplatelet effectiveness in patients with ACS. This review evaluates the INVASIVE and MEDICAL subgroup studies of the PLATO study.

    Objetive Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74) underwent surgery for atrial fibrillation associated with mitral valvular disease. All patients manifested atrial fibrillation, which started at least six months before the surgical intervention. The majority of patients (36 patients, 90%) were in NYHA class III; 34 (85%) patients had rheumatic heart disease. In addition to mitral valve surgery and radiofrequency ablation, coronary artery bypass, DeVega tricuspid annuloplasty, left ventricular aneurysm repair, and left atrial thrombus excision were performed. Following discharge from the hospital, patients' follow-up was performed as outpatient clinic examinations and the average follow-up period of patients was 18±3 months. Results While the incidence of sinus rhythm was 85.3% on the first postoperative day, it was 80% during discharge and 71% in the 1st year follow-up examination. Conclusion Radiofrequency ablation is an effective method when it is performed by appropriate surgical technique. Its rate for returning to sinus rhythm is as high as the rate of conventional surgical procedure. PMID:27849303

    QX MAN is a grid and solution file manipulation program written primarily for the PARC code and the GRIDGEN family of grid generation codes. QX MAN combines many of the features frequently encountered in grid generation, grid refinement, the setting-up of initial conditions, and post processing. QX MAN allows the user to manipulate single block and multi-block grids (and their accompanying solution files) by splitting, concatenating, rotating, translating, re-scaling, and stripping or adding points. In addition, QX MAN can be used to generate an initial solution file for the PARC code. The code was written to provide several formats for input and output in order for it to be useful in a broad spectrum of applications.

    1979-01-01

    This article gives an account of the filarial parasites found in man and their potential transmissibility to and from other vertebrate animals under natural and experimental conditions. Those species that are regarded as being primarily parasites of other vertebrates, but which also infect man, are then dealt with in greater detail. These include the subperiodic strain of Brugia malayi and perhaps also B. pahangi, both of which are found in wild and domestic carnivores and monkeys, and Dirofilaria species of dogs and racoons. The Brugia parasites develop to maturity with the production of microfilaraemia and clinical manifestations in man similar to those caused by periodic B. malayi in man. Human dirofilariasis, on the other hand, represents a transmission cul-de-sac for the parasite. Clinical manifestations are mild or absent and generally the worms do not mature and, even if they do, they rarely give rise to microfilaraemia. D. immitis causes pulmonary dirofilariasis, and D. repens and D. tenuis give rise to subcutaneous nodules in man. The diagnosis of dirofilariasis depends on an awareness of the infection in the animal reservoirs and of the possibility of man being exposed to bites of infected vectors.

    Impaired right ventricular systolic function (RVSF) may complicate the treatment of constrictive pericarditis (CP) by pericardiectomy, which is a procedure that remains with significant morbidity and mortality. We evaluated RVSF in patients with CP who underwent pericardiectomy to determine the prognostic value of RVSF. RVSF was assessed by measuring Tricuspid Annular Plane Systolic Excursion (TAPSE) in 35 patients (mean age 52 ± 15.4 years) who underwent pericardiectomy. Thirty-one patients (88.6%) had reduced RVSF (TAPSE ≤1.8 cm). Eight patients (23%) had postoperative events (heart failure 3 and hospital mortality 5). Logistic regression showed that concomitant coronary artery bypass grafting (CABG) (p = 0.052), left ventricular ejection fraction (p = 0.059), left atrial diameter (p = 0.028), and TAPSE (p = 0.016) were borderline or significant univariate predictors of events. TAPSE (p = 0.018, odds ratio = 0.605 [0.40 to 0.92]) and CABG (p = 0.033, odds ratio = 20 [1.26 to 315]) were independent predictors of events on multivariate analysis. Stepwise analysis showed that TAPSE provided incremental prognostic value (p = 0.029, chi-square increase 11.6 to 16.3) to the combination of CABG, ejection fraction, and left atrial diameter. Receiver-operating characteristic curve analysis showed an area under the curve of 0.815 for TAPSE. TAPSE of 1.38 cm had a sensitivity of 88% and specificity of 67% for identifying patients with events. TAPSE was also inversely related to the length of hospital stay after pericardiectomy (p = 0.02, R = -0.424). Hence, our study showed that RVSF is frequently reduced in patients with CP who underwent pericardiectomy. In conclusion, TAPSE is an independent predictor of events and provides incremental prognostic value to other clinical and echocardiographic variables.

    Background: Patients who undergo cardiac surgery appear to be at increased risk for the development of Nosocomial infections (NIs). The development of antibiotic-resistant infections has been associated with significantly greater hospital mortality rates compared to similar infections caused by antibiotic-sensitive pathogens. Objectives: The purpose of this study is survey of Nis and antibiotic resistance patterns of causative bacteria among patients who underwent open heart surgery in the north of Iran during a 2-year period between September 2012 and September 2014. Methods: In this cross-sectional study we evaluated 187 patients that underwent open heart surgery with NIs. Demographic feature, clinical characteristics and risk factors of each infection were recorded. The antibiotic susceptibility test was performed using the Minimum inhibitory concentration (MIC) method according to the standard protocol of Clinical & Laboratory Standards Institute (CLSI). Detection of Extended-spectrum beta-lactamase (ESBL) producing bacteria was performed by the double-disk synergy (DDS) test; also Methicillin-resistant Staphylococcus (MRSA) strains were identified by MRSA Screen Agar. The collected data were analyzed using the SPSS software (ver. 16) and, descriptive statistics were used. Results: Out Of total of 2253 hospitalized patients who underwent open heart surgery, 187(5.05%) patients had NIs. 51.9% of the patients were female. The rates of surgical site infection (SSI), respiratory tract infection, endocarditis, Urinary tract infection (UTI), blood Infection and mediastinitis were 27.80, 25.66%, 17.64, 17.11% 8.55% and 3.20% respectively. E.coli and S.aureus were the most causative agents of NIs. The rate of ESBL-producing bacteria was 14.28- 71.42% among enterobacteriaceae and the rate of MRSA was 54.2% among S.aureus strains. All isolated Acinetobacter.spp were Multi-drug resistance (MDR). Conclusions: We showed that the rate of NIs among these high-risk patients

    We report a case of 70 years old male who underwent percutaneous nephrolithotomy for renal calculi. After an uneventful recovery from anaesthesia, the patient developed delirium which manifested as restlessness, agitation, irritability and combative behavior. All other clinical parameters including arterial blood gas, chest X-ray and core temperature were normal and the patient remained haemodynamically stable. But 45 min later the patient developed florid manifestations of septic shock. He was aggressively managed in a protocolized manner as per the Surviving Sepsis Guidelines in the Critical Care Unit and recovered completely. There are no case reports showing postoperative delirium as the only initial presentation of severe sepsis, with other clinical parameters remaining normal. Both urosepsis and sepsis associated delirium have very high mortality. High index of suspicion and a protocolized approach in the management of sepsis can save lives.

    Posterior reversible encephalopathy syndrome (PRES) usually manifests with severe headaches, seizures, and visual disturbances due to uncontrollable hypertension. A patient (age in the early 60s) with a history of renal cell cancer presented with lower-extremity weakness and paresthesias. Magnetic resonance imaging (MRI) of the thoracic spine revealed a T8 vertebral body metastatic lesion with cord compression at that level. The patient underwent preoperative embolization of the tumor followed by posterior resection and placement of percutaneous pedicle screws and rods. Postoperatively, the patient experienced decreased visual acuity bilaterally. Abnormal MRI findings consisted of T2 hyperintense lesions and fluid-attenuated inversion recovery changes in both occipital lobes, consistent with the unique brain imaging pattern associated with PRES. The patient's blood pressure was normal and stable from the first day of hospitalization. The patient was kept on high-dose steroid therapy, which was started intraoperatively, and improved within 48 hours after symptom onset.

    The congenital absence of a skeletal muscle is a rare cause of congenital muscular torticollis, and the condition is associated with various unusual anatomical structures. We describe a rare case of congenital absence of the sternocleidomastoid muscle associated with squamous cell carcinoma of the tongue in a patient who underwent neck dissection. In this case, both the external jugular vein and the spinal accessory nerve were absent. However, we found that branches of the C3 nerve extended from the cervical plexus to the trapezius muscle and seemed to be acting as trapezius muscle motor nerves in place of the accessory nerve. After the operation, the patient was able to lift and abduct his right arm, and his shoulder did not droop.

    Objectives: To compare clinical outcomes of cases who underwent deep anterior lamellar keratoplasty (DALK) and cases who were converted to penetrating keratoplasty (PKP) from DALK surgery. Materials and Methods: The records of 54 patients for whom DALK surgery was planned and were operated for different diagnoses between March 2013 and June 2015 were retrospectively analyzed. Patients were divided into two groups: group 1 (PKP group) consisted of 23 cases who were converted to PKP due to Descemet’s membrane perforation at any stage of surgery; group 2 (DALK group) consisted of 31 patients whose surgery could be completed as DALK. Preoperative and postoperative follow-up results were evaluated in each group. Results: Corrected distance visual acuity (CDVA) increased in the postoperative period according to baseline in both groups. However, there was no statistically significant difference in the rates of CDVA increase between the groups (p=0.142). The mean astigmatism measured by corneal topography at final examination was 5.8±2.3 diopters in group 1 and 5.4±1.8 diopters in group 2. The difference between groups was not statistically significant (p=0.430). The groups were not statistically different regarding postoperative pachymetry (p=0.453). The grafts in all 54 patients (100%) were clear at final postoperative examination. There were no statistically significant differences between the groups in terms of postoperative complications. Conclusion: Similar clinical outcomes were obtained in our study for patients who underwent DALK and those whose procedure was converted from DALK to PKP.

    Malnutrition has been identified as an important predictor of poor clinical outcomes in patients with heart failure. The aim of this study is to examine the prognostic impact of nutritional status in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). The impact of nutrition, assessed using the geriatric nutritional risk index (GNRI) calculated by serum albumin and body mass index, was evaluated in 2,853 patients with CAD who underwent their first PCI between 2000 and 2011. Patients were assigned to tertiles based on their GNRI levels. The incidences of all-cause death and cardiac death were assessed. The median GNRI values were 101 (interquartile range 95 to 106). Lower GNRI levels were associated with older age and higher prevalence of acute coronary syndrome and chronic kidney disease. During the median follow-up period of 7.4 years, Kaplan-Meier curves showed ongoing divergence in rates of mortality among tertiles (GNRI <98: 35.1%; 98 to 104: 20.6%; ≥104: 12.1%; log-rank p <0.0001). Stratification analysis by age also showed that the lowest GNRI tertile was associated with mortality in both patients <65 years and those ≥65 years. After adjusting for established cardiovascular risk factors, lower GNRI was an independent predictor of all-cause death (hazard ratio 1.55 per 10 decrease, 95% confidence interval 1.30 to 1.84, p <0.0001) and cardiac death (hazard ratio 1.44, 95% confidence interval 1.08 to 1.90, p = 0.01). In conclusion, nutritional status was associated with long-term clinical outcomes in CAD patients after PCI. Evaluation of GNRI carries important prognostic information and may guide the therapeutic approach to such patients.

    Abstract The prevalence of cognitive impairment and orthostatic hypotension (OH) increases with age, but the results of studies that assessed possible associations between them are inconsistent. The aim of this study is to assess possible associations between cognitive impairment and OH in patients ≥65 years of age who underwent a comprehensive geriatric assessment. A retrospective analysis was conducted of the computerized medical records of the study population from 2005 to 2013. Data collected included blood pressure measurements that enabled the calculation of OH, results of the mini-mental state examination (MMSE), results of the Montreal cognitive assessment (MoCA) test, and cognitive diagnoses that were determined over the course of the assessment. The rate of OH in the study population of 571 adults was 32.1%. The mean MMSE score was 22.5 ± 5.2 among participants with OH and 21.6 ± 5.8 among those without OH (P = 0.09). The absence of a significant association between OH and MMSE remained after adjusting the MMSE score for age and education level. The mean MoCA score was 16.4 ± 5.0 among participants with OH and 16.4 ± 4.8 among those without (P = 0.33). The prevalence of OH was 39% among participants without cognitive impairment, 28.9% among those with mild cognitive impairment (MCI), and 30.6% among those with dementia (P = 0.13). There was no association between OH and cognitive impairment in adults who underwent a comprehensive geriatric assessment. PMID:27442658

    The presence of the appendix within a femoral hernia (FH) sac is known as Garengeot's hernia (GH). We report on current study a rare case of an elderly man with a combined inguinal and Garengeot's hernia and discuss the clinical aspects. An 82-year-old man clinically stable, presented history of pain at the right inguinal region for over a week, without vomit, nausea, fever or any alteration of intestinal or urinary eliminations. Clinical examination revealed a FH and the ultrasonography confirmed the hernia sac. During the surgery, the appendix was recognized within the sac, and then, the patient underwent appendectomy and hernia repair. In conclusion, the presence of the vermiform appendix in a FH sac is rare, thus, requiring knowledge of the surgeon regarding this clinical entity. Prompt diagnosis and appropriate surgical treatment is the key to avoid complications. PMID:27381019

A CT scan of the neck performed with contrast showed a phlegmon in the region of the right parotid tail measuring approximately 2.5×2.4 cm. Cultures of the aspirated fluid grew Streptococcus pneumoniae and the S. pneumoniae urinary antigen test was also positive. The patient underwent surgical debridement and received antimicrobial therapy with complete resolution of the parotitis. Parotitis caused by S. pneumoniae is rare, and HIV infection should be suspected in any case of invasive pneumococcal disease.

    Stem cell transplantation (SCT) is an intensive therapy offering the possibility of cure for life-threatening conditions but with risk of serious complications and death. Outcomes associated with pediatric palliative care (PPC) for children who undergo SCT are unknown. Therefore, we evaluated whether PPC consultation is associated with differences in end-of-life (EOL) care patterns for children who underwent SCT and did not survive. Medical records of children who underwent SCT at Boston Children's Hospital/Dana-Farber Cancer Institute for any indication from September 2004 to December 2012 and did not survive were reviewed. Child demographic and clinical characteristics and PPC consultation and EOL care patterns were abstracted. Children who received PPC (PPC group) were compared with those who did not (non-PPC group). Children who received PPC consultation (n = 37) did not differ from the non-PPC group (n = 110) with respect to demographic or clinical characteristics, except they were more likely to have undergone unrelated allogeneic SCT (PPC, 68%; non-PPC, 39%; P = .02) or to have died from treatment-related toxicity (PPC, 76%; non-PPC, 54%; P = .03). PPC consultation occurred at a median of .7 months (interquartile range [IQR], .4 to 4.2) before death. PPC consultations most commonly addressed goals of care/decision-making (92%), psychosocial support (84%), pain management (65%), and non-pain symptom management (70%). Prognosis discussions (ie, the likelihood of survival) occurred more commonly in the PPC group (PPC, 97%; non-PPC, 83%; P = .04), as did resuscitation status discussions (PPC, 88%; non-PPC, 58%; P = .002). These discussions also occurred earlier in the PPC group, for prognosis a median of 8 days (IQR, 4 to 26) before death compared with 2 days (IQR, 1 to 13) in the non-PPC group and for resuscitation status a median of 7 days (IQR, 3 to 18) compared with 2 days (IQR, 1 to 5) in the non-PPC group (P < .001 for both of the timing

    Fifty-eight patients (mean age 18.4 years) who had received splint therapy for internal derangement of the temporomandibular joint (TMJ) were examined retrospectively to investigate the efficacy of occlusal reconstruction by orthodontic treatment. The subjects were divided into three groups: 18 patients (mean age 18.6 years) who underwent orthodontic treatment combined with the use of splints (ST group); 27 patients (mean age 18.2 years) who underwent orthodontic treatment without the use of splints (NST group); and 13 patients (mean age 17.9 years) who received only splint therapy for temporomandibular joint disorders (TMD; control group). TMJ sound, pain on movement and restriction of mandibular movement were examined at the initial examination (T1), at the end of the splint therapy for TMD or beginning of orthodontic treatment (T2), at the end of orthodontic treatment (T3), and at recall or 1 year after orthodontic treatment (T4). The following results were found. (1) The percentage of patients with no joint sound at T2 was 20-30 per cent. The percentage of such patients in both the ST and NST groups increased to over 50 per cent at T3, but slightly decreased to 39-50 per cent at T4. There were no significant inter-group differences at any time point. (2) The number of patients who had no pain on movement at T2 was 60-80 per cent. The percentage of such patients in both the ST and NST groups increased to over 90 per cent at T3, but then slightly decreased to 80 per cent at T4. There were no significant inter-group differences at any time point. (3) None of the patients showed restriction of movement of the TMJ at T2 or T4. One patient in the ST group was found to have restriction at T3. There were no significant inter-group differences at any time point. (4) The most frequent type of malocclusion in both ST and NST groups was anterior open bite. These results suggest that TMD symptoms that have been eliminated by splint therapy are not likely to recur due to

    The development of antimatter engines for spacecraft propulsion will allow man to expand to the nearest stellar neighbors such as the Alpha Centuri system. Compared to chemically powered rockets like the Apollo mission class which would take 50,000 years to reach the Centauri system, antimatter propulsion would reduce one way trip time to 30 years or less. The challenges encountered by manned interstellar travel are formidable. The spacecraft must be a combination of sublight speed transportation system and a traveling microplanet serving an expanding population. As the population expands from the initial 100 people to approximately 300, the terraformed asteroid, enclosed by a man-made shell will allow for expansion over its surface in the fashion of a small terrestrial town. All aspects of human life - birth; death; physical, emotional, and educational needs; and government and law must be met by the structure, systems, and institutions on-board.

    The start of the Third Millennium will be highlighted by the establishment of man's extraterrestrial civilization with three technical cornerstones leading to the off-planet expansion of the human resource base. These are (1) the availability of compact energy sources for power and propulsion, (2) the creation of permanent manned habitats in space, and (3) the ability to process materials anywhere in the Solar System. In the 1990s and beyond, nuclear reactors could represent the prime source of both space power and propulsion. The manned and unmanned space missions of tomorrow will demand first kilowatt and then megawatt levels of power. Various nuclear power plant technologies will be discussed, with emphasis on derivatives from the nuclear rocket technology.

    A computerized anatomical man (CAM) model, representing the most detailed and anatomically correct geometrical model of the human body yet prepared, has been developed for use in analyzing radiation dose distribution in man. This model of a 50-percentile standing USAF man comprises some 1100 unique geometric surfaces and some 2450 solid regions. Internal body geometry such as organs, voids, bones, and bone marrow are explicitly modeled. A computer program called CAMERA has also been developed for performing analyses with the model. Such analyses include tracing rays through the CAM geometry, placing results on magnetic tape in various forms, collapsing areal density data from ray tracing information to areal density distributions, preparing cross section views, etc. Numerous computer drawn cross sections through the CAM model are presented.

  15. The cost of landing man on Mars

    1984-01-01

    In a period where the space program budget is generally static at about 1/3 of the level reached during the Apollo program, manned planetary flight is not considered by NASA planners to be a realistic near term goal. Much of NASA's current planning is based on the perception that manned planetary flight would be more costly than the Apollo lunar landing. This paper demonstrates that with current technological improvements in avionics, structure, and space transportation, the landing of an American on Mars would cost only 1/3 to 2/3 of the lunar landing; on a per capita basis such a program would cost less than $200, compared to Apollo's $325 (all dollars in 1981 base). Given the fact that a manned Mars landing is the last such exploration feat left to this generation, the cost should clearly not be a major deterrent.

    Background: Bariatric operations have variable range of complications and postoperative benefits. Gastroesophageal reflux is considered potential factor that may result in damage to the esophageal mucosa and this subject is quite controversial in the literature. Aim : To evaluate patients who underwent to Roux-en-Y gastrojejunal bypass correlating epidemiologic and endoscopic findings in pre and postoperative periods. Method : A retrospective, paired study which evaluated 110 patients. Inclusion criteria were formal indication for bariatric surgery and patients with pre and postoperative endoscopy. Exclusion criteria were previous bariatric surgery, patients subjected to other types of bariatric surgery and those who had no pre or postoperative upper digestive endoscopy. The epidemiological variables were: sex, age, body mass index, type 2 diabetes mellitus or impaired glucose tolerance, and preoperative dyslipidemia. Results : The preoperative upper endoscopy was normal in 26.4% of the patients. Among endoscopic alterations, the hiatus hernia was the most prevalent followed by non-erosive gastritis. The postoperative upper endoscopy was normal in 40.9% and stenosis was the most prevalent followed by marginal ulcer. Correlation on pre and postoperative endoscopies, was found 100% reduction of hiatal hernias and 88% of esophagitis. There was no statistical significance in relationship to anastomotic stenosis with preoperative other variables. Conclusions: There was significant decrease in postoperative hiatus hernia, erosive esophagitis, non-erosive esophagitis, erosive gastritis and non-erosive gastritis with the operation. Stenosis of the gastrojejunostomy anastomosis was the most prevalent postoperative complication with no correlation with preoperative variables. PMID:27120737

    2016-01-01

    Patients who underwent resection of maxilla due to benign or malignant tumor, or accident will have defect in palatal area. They get retention, support and stability from remaining tissues which are hardly optimal. The advantage of swing-lock attachment design is having multiple contacts on labial and lingual side of the abutment teeth by retentive strut and palatal bracing component. Because the force is distributed equally to abutment teeth, abutment teeth of poor prognosis can be benefited from it. It is also more advantageous to cover soft tissue defects which are hard to reach with conventional prosthesis. A 56-year-old female patient who had undergone a maxillectomy due to malignant melanoma complaining of loose and unstable surgical obturator. Surveyed crowns were placed on #12, 26, and 27. Teeth #11, 21, 22, and 23 had lingual rest seat and #24 had mesial rest seat to improve stability and support of the obturator. This clinical report presents the prosthetic management of a patient treated with obturator on the maxilla using swing-lock attachment to the remaining teeth. PMID:27826392

    Background: The aim of this study was to evaluate the efficacy of low-level laser therapy for reducing the acute pain of sternotomy in patients who underwent a coronary artery bypass graft (CABG). Methods: This study was conducted with ninety volunteers who electively submitted to CABG. The volunteers were randomly allocated into three groups of equal size (n = 30): control, placebo, and laser (λ of 660 nm and spatial average energy fluency of 1.06 J/cm2). Pain when coughing was assessed by a visual analog scale (VAS) and McGill Pain Questionnaire, according to sensory, affective, evaluative, and miscellaneous domains. The patients were followed for 1 month after the surgery. Results: The laser group had a greater decrease in pain with analogous results, as indicated by both the VAS and the McGill questionnaire (P ≤ 0.05) on sensory and affective scores, on days 6 and 8 postsurgery compared to the placebo and control groups. Conclusion: Laser seems to be effective promoting pain reduction after coronary-arterial bypass grafting. PMID:28074796

    Conservative surgery is considered the procedure of choice for women who are affected by early stage tumours. The local recurrence of cancer as a consequence of breast tissue conservation is a growing concern. This study aimed to describe the sociodemographic and clinical profiles of women who had local recurrences of breast cancer after conservative surgery and to examine the associations between sociodemographic and clinical variables and the incidence of tumour recurrence in these women. The retrospective cohort included 880 women who were diagnosed with breast cancer and underwent conservative surgery between January 2000 and December 2010. Recurrences occurred in 60 patients, and the mean age of the women at diagnosis was 48.8 years. Predictive factors for local recurrence were young age (<39 years) (P = 0.028 and OR = 10.93), surgical margin involvement (P = 0.001 and OR = 3.66), and Her-2 overexpression (P = 0.045 and OR = 1.94). The establishment of sociodemographic and clinical characteristics might help to select optimum treatments, which is a crucial challenge for public health in Brazil, especially with regard to reductions of surgery and hospitalisation expenditures in the Unified Health System (Sistema Único de Saúde—SUS).

    To evaluate the effects of preoperative highly sensitive C-reactive protein (Hs-CRP) in serum on the prognostic outcomes of patients with hepatocellular carcinoma (HCC) following hepatic resection in Chinese samples.From January 2004 to December 2008, a total of 624 consecutive HCC patients who underwent hepatic resection were incorporated. Serum levels of Hs-CRP were tested at preoperation via a collection of venous blood samples. Survival analyses adopted the univariate and multivariate analyses.In our study, among the 624 screened HCC patients, 516 patients were eventually incorporated and completed follow-up. Positive correlations were found regarding preoperative serum Hs-CRP level and tumor size, Child-Pugh class, or tumor stage (all P < 0.0001). Patients with recurrence outcomes and nonsurvivors had increased Hs-CRP levels at preoperation (both P < 0.0001). When compared to the Hs-CRP-normal group, the overall survival (OS) and recurrence-free survival rates were evidently decreased in the Hs-CRP-elevated group. Further, preoperative serum Hs-CRP level might be having possible prediction effect regarding survival and recurrence of HCC patients after hepatic section in the multivariate analysis.Preoperative increased serum Hs-CRP level was an independent prognostic indicator in patients with HCC following hepatic resection in Chinese samples.

    Objective To determine what patient- and facility-level characteristics drive late specialized rehabilitation among veterans who already received immediate postoperative services. Design Data were obtained from 8 administrative databases for 2,453 patients who underwent lower extremity amputation in Veterans Affairs Medical Centers in 2002-2004. A Cox proportional hazards model was used to determine the hazards ratios and 95% confidence intervals of the factors associated with days to readmission for late services after discharge from the surgical hospitalization. Results There were 2,304 patients who received only immediate postoperative services, while 152 also received late specialized rehabilitation. After adjustment, veterans who were less disabled physically, residing in the South Central compared to the Southeast region, and had their surgeries in CARF accredited facilities were all more likely to receive late services. The hazards ratios for type of immediate postoperative rehabilitation were not constant over time. At hospital discharge, there was no difference in receipt, however, after 3 months, those who received early specialized rehabilitation were significantly less likely to receive late services. Conclusion The factors associated with late specialized rehabilitation were due mainly to facility-level characteristics and care process variables. Knowledge of these factors may help with decision-making policies regarding CARF accredited units. PMID:21389847

    NASA's Constellation Program is developing its next generation manned space systems for missions to the International Space Station (ISS) and the Moon. The Program is embarking on a path towards standards based Internet Protocol (IP) networking for space systems communication. The IP based communications will be paired with industry standard security mechanisms such as Internet Protocol Security (IPsec) to ensure the integrity of information exchanges and prevent unauthorized release of sensitive information in-transit. IPsec has been tested in simulations on the ground and on at least one Earth orbiting satellite, but the technology is still unproven in manned space mission situations and significant obstacles remain.

    Further evidence for a diagnosis of the Elephant Man's condition is reviewed. It is known that the Elephant Man had "mocassin" lesions, hyperostoses of the skull, and absence of café-au-lait spots, all of which are characteristic of Proteus syndrome. Recently, questions have been raised about his skeletal findings and their relevance to neurofibromatosis. However, other skeletal diagnoses have been entertained, including Maffucci syndrome, Paget's disease of bone, pyarthrosis, and fibrous dysplasia. These diagnostic possibilities are discussed and evaluated critically. It is concluded that the skeletal findings are most consistent with Proteus syndrome and coincidental hip disease secondary to childhood trauma.

The main objective of the current study was to investigate the effects of FLIRT (First Line Intermittent Recompression Technique) on bubble detection in man. 29 divers underwent 2 simulated dives in a dry recompression chamber to a depth of 40 msw (500 kPa ambient pressure) in random order. A Buehlmann-based decompression profile served as control and was compared to an experimental profile with intermittent recompression during decompression (FLIRT). Circulating bubbles in the right ventricular outflow tract (RVOT) were monitored by Doppler ultrasound and quantified using the Spencer scoring algorithm. Heat shock protein 70 (HSP70), thrombocytes, D-Dimers and serum osmolarity were analyzed before and 120 min after the dive. Both dive profiles elicited bubbles in most subjects (range Spencer 0-4). However, no statistically significant difference was found in bubble scores between the control and the experimental dive procedure. There was no significant change in either HSP70, thrombocytes, and D-Dimers. None of the divers had clinical signs or symptoms suggestive of DCS. We conclude that FLIRT did not significantly alter the number of microbubbles and thus may not be considered superior to classical decompression in regards of preventing DCS.

    Objective: To quantify the extent and complexity of residual coronary stenosis following PCI by the residual SYNTAX score, and to evaluate its impact on adverse ischemic outcomes in acute coronary syndrome(ACS) patients. Methods: From January 2013 to December 2013, a total of 1 414 consecutive moderate- and high-risk ACS patients who underwent any PCI with multi-vessel coronary artery disease were evaluated.Patients were stratified by rSS quartiles and their outcomes were compared. Results: The rSS was 4.8±6.7. 591 patients (41.8%) had rSS=0(CR), 233 patients (16.5%) had rSS>0 but ≤ 3, 296 patients (20.9%) had rSS>3 but ≤8 and 294 patients (20.8%) had rSS>8.Clinical risk factors were more frequent in patients with incomplete revascularization(IR) compared with complete revascularization(CR). The 2-year rates of all-caused death(1.2% vs 0.4%, 2.0%, 4.4%, P=0.003), cardiac death, revascularization and MACCE were significantly higher in high rSS group, compared to other groups.By multivariable analysis, rSS was a strong independent predictor of ischemic outcomes at 2-year, including all-cause mortality (HR=1.05, 95%CI 1.01-1.09, P=0.019), cardiac death, revascularization and MACCE. Conclusions: The rSS is a strong independent predictor of all-caused death, cardiac death, revascularization and MACCE and has moderated predictive ability for those ischemic outcomes.

    Background: The aim of the study was to determine the correlation between clinical and echocardiographic findings and risk factors of patients with suspected acute pulmonary thromboembolism (PTE) who underwent computed tomography pulmonary angiography (CTPA). Materials and Methods: In this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of PTE referred to imaging center of our hospital from different wards for CTPA were enrolled. The frequency of different clinical presentations, risk factors, items of Wells’ criteria, and echocardiographic findings was compared in patients with and without PTE, which have been diagnosed according to the CTPA results. Results: PTE was diagnosed in 53 (17.1%) of patients with suspected PTE. From clinical manifestations, tachypnea, pleuritic chest pain, and edema of lower extremities were significantly more frequent among patients with PTE (P < 0.05). Major surgery was the risk factor which was significantly more prevalent among patients with PTE (P < 0.05). Frequency of all criteria of Wells’ criteria, except hemoptysis, was significantly higher in patients with PTE (P < 0.05). The frequency of all studied echocardiographic variables was significantly higher in patients with PTE (P < 0.05). Conclusion: It is suggested that we could use the results of this study for utilizing the diagnostic process of PTE in patients with highly clinical suspicion of PTE and providing more validated decision. Using the results of this study, we could identify high-risk patients and made appropriate risk assessment for better management of patients with suspected PTE as well as reduce the rate of unnecessary CTPA and its related adverse consequences.

    2007-01-01

    Albert Schweitzer, the great missionary physician from the XXth century, had a versatile personality that integrated multiple talents, leading to the slightly frequent conjunction of the thinker with the man of action, and the humanist with the scientist and the artist. He studied all these disciplines in a brilliant manner: Philosophy, Theology, Music and Medicine; he was also a great scholar of Bach's work, Jesus Christ and the civilization history. In his maturity, this great man renounced to the fame and glory gained as intellectual and musician, to dedicate his life as a physician for the forgotten African natives. His deeply religious spirit allowed him to penetrate into the most recondite of the human soul; in his personality, he expressed in its entire dimension the eternally unsatisfied desire of the solitary man, against the immensity of the universe. His philosophy, based on the respect for life, was realized throughout the practice of the medical profession. His noble character and personality was based on the man as symbol, since it was not so much what he did helping people but what people could do to others due to him. His singular example represented a moral force in the world, superior to millions of men armed for a war. In 1953, he received the Nobel Peace Prize for his philanthropic work in Africa during more that fifty years, and for his deep love to the living beings. He was transformed in a perennial legend as the Lambaréné doctor.

  7. Animals, disease, and man: making connections.

    PubMed

    Hardy, Anne

    2003-01-01

    The intricate causal relationships between disease in man and disease in animals first began to be elucidated in the mid-19th century. Although the connections between animal and human disease are now generally understood, individuals as well as societies remain slow to act on this knowledge. This paper examines the gradual recognition of these disease connections and explores the parallel theme of man's reluctance to appreciate the implications of these connections. It identifies factors that have inhibited the realization of the links between disease in man and animals, and discusses several milestones in the scientific elucidation of these links. Beginning with emerging concerns over the relationship between bovine and human tuberculosis in the 1860s, it follows the discovery of insect vectors, animal reservoirs, and the links between animals, influenza, and man. Despite warnings of the potential significance for human disease of patterns of changes in the relationship with animals and the natural world, scientists have continued to treat human and animal health as largely independent disciplines, while historians too have neglected this important aspect of human disease.

    Since the first U.S. manned entry, Mercury (May 5, 1961), seventy-five manned entries have been made resulting in significant progress in the understanding and development of Thermal Protection Systems (TPS) for manned rated spacecraft. The TPS materials and systems installed on these spacecraft are compared. The first three vehicles (Mercury, Gemini, Apollo) used ablative (single-use) systems while the Space Shuttle Orbiter TPS is a multimission system. A TPS figure of merit, unit weight lb/sq ft, illustrates the advances in TPS material performance from Mercury (10.2 lb/sq ft) to the Space Shuttle (1.7 lb/sq ft). Significant advances have been made in the design, fabrication, and certification of TPS on manned entry vehicles (Mercury through Shuttle Orbiter). Shuttle experience has identified some key design and operational issues. State-of-the-art ceramic insulation materials developed in the 1970's for the Space Shuttle Orbiter have been used in the initial designs of aerobrakes. This TPS material experience has identified the need to develop a technology base from which a new class of higher temperature materials will emerge for advanced space transportation vehicles.

  16. Asphalt and risk of cancer in man.

    PubMed Central

    Chiazze, L; Watkins, D K; Amsel, J

    1991-01-01

    Epidemiological publications regarding the carcinogenic potential of asphalt (bitumen) are reviewed. In 1984 the International Agency for Research on Cancer (IARC) stated that there is "inadequate evidence that bitumens alone are carcinogenic to humans." They did, however, conclude that animal data provided sufficient evidence for the carcinogenicity of certain extracts of steam refined and air refined bitumens. In the absence of data on man, IARC considered it reasonable to regard chemicals with sufficient evidence of carcinogenicity in animals as if they presented a carcinogenic risk to man. Epidemiological data for man accumulated since the IARC report do not fulfil the criteria for showing a causal association between exposure to asphalt and development of cancer. The studies cited all suffer from a lack of data on exposure or potential confounders, which are necessary to establish whether or not such an association may or may not exist. In view of the evidence (or lack thereof) regarding asphalt today, an appropriate public health attitude suggests at least that action be taken to protect those working with asphalt by monitoring the workplace, taking whatever steps are possible to minimise exposures and to inform workers of potential hazards. At the same time, a need exists for well designed analytical epidemiological studies to determine whether a risk of cancer in man exists from exposure to asphalt. PMID:1878310

  18. How was the Turin Shroud Man crucified?

    PubMed

    Bevilacqua, M; Fanti, G; D'Arienzo, M; Porzionato, A; Macchi, V; De Caro, R

    2014-12-01

    As the literature is not exhaustive with reference to the way the Turin Shroud (TS) Man was crucified, and it is not easy to draw significant information from only a "photograph" of a man on a linen sheet, this study tries to add some detail on this issue based on both image processing of high resolution photos of the TS and on experimental tests on arms and legs of human cadavers. With regard to the TS Man hands, a first hypothesis states that the left hand of the TS Man was nailed twice at two different anatomical sites: the midcarpal joint medially to the pisiform between the lunate/pyramidal and capitate/uncinate bones (Destot's space) and the radiocarpal joint between the radio, lunate and scaphoid; also the right hand would have been nailed twice. A second hypothesis, preferred by the authors, states that the hands were nailed only once in the Destot's space with partial lesion of the ulnar nerve and flexion of the metacarpophalangeal joint of the thumbs. With regard to the TS Man feet, the imprint of the sole of the right foot leads to the conclusion that TS Man suffered a dislocation at the ankle just before the nailing. The entrance hole of the nail on the right foot is a few inches from the ankle, and excludes a double nailing. The nail has been driven between the tarsal bones. The TS Man suffered the following tortures during crucifixion: a very serious and widespread causalgia due to total paralysis of the upper right limb (paradoxical causalgia); a nailing of the left wrist with damage to the ulnar nerve; a similar nailing of the right wrist; and a nailing to both feet using one only nail that injured the plantaris medialis nerves. The respiratory limitation was probably not sufficient to cause death by asphyxiation. Also considering the hypovolemia produced by scourging and the many other tortures detectable on the TS, the principal cause of death can be attributed to a myocardial infarction.

    Human explorers had a fundamental role in the success of the APOLLO moon programme, they were at the same time the indispensable pilots, scientific operators and on the last missions lead scientists. Since, man did not either return to the moon or land on Mars but manned operation centres on the earth are now conducting extensive telescience on both celestial bodies. Manned flights to moon, Mars and asteroids are however still on the agenda and even if the main drive of these projects is outside science, it is to the planetary scientists to both prepare the data bases necessary for these flights and to ensure that the scientific advantage of conducting research in real time and in situ is exploited to the maximum. The current manned flight programme in Europe concentrates on the use of the International Space Station, the scientific activities can be roughly divided between the pressurized payloads and the external payloads. Technology developments occur also in parallel and prepare new exploration techniques. The current planning leads to exploitation up to 2020 but the space agencies study further extensions, the date of 2028 having already been considered. The relation of these programmes to future manned planetary exploration will be described both from the science and development point of view. The complementary role of astronauts and ground operation centres will be described on the basis of the current experience of operation centres managing the International Space Station. Finally, the NASA ORION project of exploration in the solar system will be described with emphasis on its current European participations. The science opportunities presented by independent ventures as Inspiration Mars or Mars One will be presented.

    The objective of the present study was to test whether a perioperative course of colchicine, in patients who underwent standard coronary artery bypass grafting, would result in reduced postoperative increase of myocardial injury biomarker levels. Patients were prospectively randomized to colchicine or placebo starting 48 hours before scheduled coronary artery bypass grafting and for 8 days thereafter (0.5 mg twice daily). The primary outcome parameter was maximal high-sensitivity troponin T (hsTnT) concentration within 48 hours after surgery. Secondary outcome measures were maximal creatine kinase-myocardial brain fraction (CK-MB) levels and area under the curve (AUC) of hsTnT and CK-MB concentrations; 59 patients were included. Maximal hsTnT was 616 pg/ml (396 to 986) in the colchicine group versus 1,613 pg/ml (732 to 2,587) in controls (p = 0.002). Maximal CK-MB was 44.6 ng/ml (36.6 to 68.8) and 93.0 ng/ml (48.0 to 182.3), respectively (p = 0.002). The median AUC for hsTnT was 40,755 pg h/ml (20,868 to 79,176) in controls versus 20,363 pg h/ml (13,891 to 31,661) in the colchicine group (p = 0.002). AUCs for CK-MB were 2,552 ng h/ml (1,564 to 4,791) in controls and 1,586 ng h/ml (1,159 to 2,073) in the colchicine group (p = 0.003). The main complaints associated with colchicine were, as expected, gastrointestinal, with 5 patients (16.7%) in the colchicine group reporting diarrhea versus 1 control (3.4%) (p = 0.195). In conclusion, a short perioperative course of colchicine was effective in attenuating postoperative increases of hsTnT and CK-MB compared with placebo. This finding, which needs confirmation in a larger clinical trial powered to assess clinical endpoints, suggests a potential role for this agent in reducing cardiac surgery-related myocardial damage.

    2016-01-01

    Background The world’s population is aging faster and the incidence of acute kidney injury (AKI) needing continuous renal replacement therapy (CRRT) is increasing in elderly population. The outcome of AKI needing CRRT in elderly patients is known to be poor. However, the definitions of elderly used in the previous literatures were diverse and, there were few data that compared the long-term mortality rates of these patients with middle aged patients. This study was aimed to evaluate this issue. Methods This study was a single-center, retrospective cohort study of patients who underwent CRRT from January 2013 to December 2015. The patients were divided into the following four age cohorts: middle-aged (55–64), young-old (65–74), middle-old (75–84), and old-old (≥85). The short- and long-term mortality rates for each age cohort were compared. Results A total of 562 patients met the inclusion criteria. The short-term mortality rate was 57.3% in the entire cohort. Compared with the middle-aged cohort, the middle-old cohort (HR 1.48 (1.09–2.02), p = 0.012) and the old-old cohort (HR 2.33 (1.30–4.19), p = 0.005) showed an increased short-term mortality rate along with an increased SOFA score, acidemia and a prolonged prothrombin time. When we analyzed the long-term mortality rate of the 238 survived patients, the middle-old cohort (HR 3.76 (1.84–7.68), p<0.001), the old-old cohort (HR 4.40(1.20–16.10), p = 0.025), a lower BMI, the presence of liver cirrhosis, the presence of congestive heart failure and a history of sepsis were independent risk factors for the prediction of long-term mortality. Conclusion Compared with the middle-aged cohort, the middle-old and the old-old cohort showed an increased short-term and long-term mortality rate. However, in the young-old cohort, neither the short-term nor the long-term mortality rate was increased. PMID:27875571

  6. Amyloidosis: diffuse involvement of the retroperitoneum.

    PubMed

    Glynn, T P; Kreipke, D L; Irons, J M

    1989-03-01

    Systemic amyloidosis diffusely involving the retroperitoneum has not, to the authors' knowledge, been previously reported. The computed tomographic scans of a 68-year-old man showed evidence of diffuse, nonenhancing thickening of the entire retroperitoneum. This appearance mimicked retroperitoneal fibrosis, but the diagnosis of amyloidosis was confirmed at autopsy.

  7. Three synergistic studies: A Manned Lunar Outpost, a Manned Mars Explorer, and an Antarctic Planetary Testbed

    1988-01-01

    The students at the University of Houston College of Architecture undertook three synergistic studies during the 1987-1988 academic year. These studies included a Manned Lunar Outpost, a Manned Mars Explorer Mission, and an Antarctic Planetary Testbed which would provide the necessary data and facilities for testing proposed missions to the Moon, Mars and beyond. All research was based on existing or near-term technology.

  8. Neural networks in support of manned space

    NASA Technical Reports Server (NTRS)

    Werbos, Paul J.

    1989-01-01

    Many lobbyists in Washington have argued that artificial intelligence (AI) is an alternative to manned space activity. In actuality, this is the opposite of the truth, especially as regards artificial neural networks (ANNs), that form of AI which has the greatest hope of mimicking human abilities in learning, ability to interface with sensors and actuators, flexibility and balanced judgement. ANNs and their relation to expert systems (the more traditional form of AI), and the limitations of both technologies are briefly reviewed. A Few highlights of recent work on ANNs, including an NSF-sponsored workshop on ANNs for control applications are given. Current thinking on ANNs for use in certain key areas (the National Aerospace Plane, teleoperation, the control of large structures, fault diagnostics, and docking) which may be crucial to the long term future of man in space is discussed.

  9. One man electrochemical air revitalization system

    Huddleston, J. C.; Aylward, J. R.

    1975-01-01

    An integrated water vapor electrolysis (WVE) hydrogen depolarized CO2 concentrator (HDC) system sized for one man support over a wide range of inlet air conditions was designed, fabricated, and tested. Data obtained during 110 days of testing verified that this system can provide the necessary oxygen, CO2 removal, and partial humidity control to support one man (without exceeding a cabin partial pressure of 3.0 mmHg for CO2 and while maintaining a 20% oxygen level), when operated at a WVE current of 50 amperes and an HDC current of 18 amperes. An evaluation to determine the physical properties of tetramethylammonium bicarbonate (TMAC) and hydroxide was made. This provides the necessary electrolyte information for designing an HDC cell using TMAC.

    1990-01-01

    A Manned Mars Mission (M3) design study is proposed. The purpose of M3 is to transport 10 personnel and a habitat with all required support systems and supplies from low Earth orbit (LEO) to the surface of Mars and, after an eight-man surface expedition of 3 months, to return the personnel safely to LEO. The proposed hardware design is based on systems and components of demonstrated high capability and reliability. The mission design builds on past mission experience, but incorporates innovative design approaches to achieve mission priorities. Those priorities, in decreasing order of importance, are safety, reliability, minimum personnel transfer time, minimum weight, and minimum cost. The design demonstrates the feasibility and flexibility of a Waverider transfer module.

  11. Manned versus unmanned - The implications to NASP

    NASA Astrophysics Data System (ADS)

    Wierzbanowski, Theodore; Kasten, Terry D.

    1990-10-01

    The assessment of unmanned approaches to experimental aerospace vehicles in general and to the NASP program in particular is summarized. Technical requirements for NASP demonstration are presented and unmanned options for satisfying requirements are discussed. The X-30 sensitivities to technical requirements are described. A correlation of the NASP program to prior flight test programs, both manned and unmanned, is also presented. It is noted that subscale vehicles may reduce risk by as much as 18 percent for approximately $200 M. It is concluded that half-scale vehicles may reduce program risk by 60 percent, while reducing X-30 costs by 40 percent. Also, an unmanned X-30 will probably cost more than a manned X-30 due to costs associated with additional software development and ground support systems costs.

  12. Hermes: A European manned space system

    NASA Astrophysics Data System (ADS)

    Cretenet, J. C.

    Designs for manned and automatic versions of the Hermes maneuverable reentry system are outlined. The reentry glider would go piggyback or the launcher's upper stage, with its own autonomous avionics. A round trip to low Earth orbit would take 10 days, with a touchdown in Europe or Guyana. The form would be similar to the NASA shuttle. Reentry trajectory would ensure a constant flux density of 500 kw/sqm on the nose, with thermal protection keeping structural temperature below 175C. Hydrogen oxygen fuel cells would be used for auxiliary power. A 15 kN propulsion unit with sixteen 400N attitude control engines would be mounted astern, and twelve 400N engines forward. Ariane 4 is not considered powerful enough for Hermes, except for low, circular orbits. Ariane 5 could take a 50 cu m hold automatic version, or 70 cu m manned.

    1993-01-01

    The ability to service satellites has thus far been limited to low earth orbit platforms within reach of the Space Shuttle. Other orbits, such as geosynchronous orbits containing high-value spacecraft have not been attainable by a servicing vehicle. The useful life of a satellite can be extended by replacing spent propellant and damaged orbital replacement units, forestalling the need for eventual replacement. This growing need for satellite on-orbits servicing can be met by the Manned On-Orbit Servicing Equipment (MOOSE). Missions requiring orbit transfer capability, precision manipulation and maneuvering, and man-in-the-loop control can be accomplished using MOOSE. MOOSE is a flexible, reusable, single operator, aerobraking spacecraft designed to refuel, repair, and service orbiting spacecraft. MOOSE will be deployed from Space Station Freedom, (SSF), where it will be stored, resupplied, and refurbished.

  14. Man-midwifery history: 1730-1930.

    PubMed

    Shelton, D C

    2012-11-01

    This paper seeks to determine whether the man-midwives William Smellie and William Hunter deserve continuing approbation as 'Founding Fathers' of the obstetrics profession. Scrutiny of their careers reveals their involvement in murders for dissection. In addition, the man-midwifery initiative of delivery in lying-in hospitals resulted in around 1 million more deaths in Britain and Ireland between 1730 and 1930, than would have occurred had home-births remained as the norm. While some may still credit Smellie and Hunter with obstetric discoveries, their knowledge was obtained by murder-for-dissection. That indictment, together with the lying-in hospital legacy, far outweighs their discoveries. The paper invites further constructive discussion and debate, but concludes the accolade of Founding Fathers is undeserved. Any continuing endorsement of Smellie and Hunter effectively demeans the high ethical standards and reputation of current obstetric professionals.

  15. Man-machine collaboration using facial expressions

    Dai, Ying; Katahera, S.; Cai, D.

    2002-09-01

    For realizing the flexible man-machine collaboration, understanding of facial expressions and gestures is not negligible. In our method, we proposed a hierarchical recognition approach, for the understanding of human emotions. According to this method, the facial AFs (action features) were firstly extracted and recognized by using histograms of optical flow. Then, based on the facial AFs, facial expressions were classified into two calsses, one of which presents the positive emotions, and the other of which does the negative ones. Accordingly, the facial expressions belonged to the positive class, or the ones belonged to the negative class, were classified into more complex emotions, which were revealed by the corresponding facial expressions. Finally, the system architecture how to coordinate in recognizing facil action features and facial expressions for man-machine collaboration was proposed.

  16. Potential teleoperator applications in manned aerospace systems

    NASA Technical Reports Server (NTRS)

    Johnsen, E. G.

    1973-01-01

    The trend of teleoperator development is toward digital computer controlled systems which utilize local sensor-computer-actuator loops to avoid obstacles and to sense manipulator grip-and-slip. The potential applications of advanced teleoperator technology to manned aerospace systems include long manipulator booms to be mounted on the shuttle. These can transfer cargo from the space shuttle and can acquire and retrieve objects in space. Free-flying teleoperators capable of acquiring, inspecting, repairing or refurbishing satellites in orbit are another space application. Another potential application of teleoperator technology is the concept of using an anthropomorphous teleoperator in lieu of man to control aircraft or spacecraft normally controlled by a human pilot.

  17. [Man's place and anthropology in bioethics].

    PubMed

    Tomar Romero, Francisca

    2013-01-01

    From the analysis of its epistemological status, the article focuses on the philosophical fundament of bioethics, stressing the need for an authentic anthropology as a reference or starting point. Being an applied ethics, the first fundament of bioethics is in ethics. It shows how only personalistic ethics, which takes as reference the nature or essence of man, can offer objective and universal criteria. Philosophical anthropology studies man as a whole, in an integral manner, from the perspective of its nature or fundamental aspects of his being. It analyzes the distinction and relationship between the philosophical anthropology and the positive anthropologies, as well as with the physical, human and social sciences. Finally, it reflects on the current anthropological crisis and its ethical consequences.

  18. Manning's roughness coefficient for Illinois streams

    USGS Publications Warehouse

    Soong, David T.; Prater, Crystal D.; Halfar, Teresa M.; Wobig, Loren A.

    2012-01-01

    Manning's roughness coefficients for 43 natural and constructed streams in Illinois are reported and displayed on a U.S. Geological Survey Web site. At a majority of the sites, discharge and stage were measured, and corresponding Manning's coefficients—the n-values—were determined at more than one river discharge. The n-values discussed in this report are computed from data representing the stream reach studied and, therefore, are reachwise values. Presentation of the resulting n-values takes a visual-comparison approach similar to the previously published Barnes report (1967), in which photographs of channel conditions, description of the site, and the resulting n-values are organized for each site. The Web site where the data can be accessed and are displayed is at URL http://il.water.usgs.gov/proj/nvalues/.

    1986-01-01

    The discussions of the Working Group (based in large part on working papers, which will shortly be published separately) are summarized. These papers cover a broad range of subjects which need to be addressed in the formulation of such a formidable enterprise as a manned Mars program. Science objective and operations; Mars surface infrastructure and activities; mission and system concepts and configurations; life sciences; impacts on the space infrastructure; and costs, schedules, and organizations are addressed.

  1. The Man-in-the-Middle Defence

    NASA Astrophysics Data System (ADS)

    Anderson, Ross; Bond, Mike

    Eliminating middlemen from security protocols helps less than one would think. EMV electronic payments, for example, can be made fairer by adding an electronic attorney - a middleman which mediates access to a customer’s card. We compare middlemen in crypto protocols and APIs with those in the real world, and show that a man-in-the-middle defence is helpful in many circumstances. We suggest that the middleman has been unfairly demonised.

    Sleep patterns were monitored in one subject aboard each of the manned Skylab missions. In all three subjects stage 3 sleep increased during the flight and consistently decreased postflight. Stage REM was elevated, and REM latency decreased in the late postflight period. The number of awakenings remained the same or decreased during flight. No changes were observed which could be expected to adversely affect performance capability.

    We report on the first two-photon in vivo brain tissue imaging study in man. High resolution in vivo histology by multiphoton tomography (MPT) including two-photon FLIM was performed in the operation theatre during neurosurgery to evaluate the feasibility to detect label-free tumor borders with subcellular resolution. This feasibility study demonstrates, that MPT has the potential to identify tumor borders on a cellular level in nearly real-time.

    Research issues and areas are identified where increased understanding of the human operator and the interaction between the operator and the avionics could lead to improvements in the performance of current and proposed helicopters. Both current and advanced helicopter systems and avionics are considered. Areas critical to man-machine interface requirements include: (1) artificial intelligence; (2) visual displays; (3) voice technology; (4) cockpit integration; and (5) pilot work loads and performance.

  9. Kimberlites of the Man craton, West Africa

    NASA Astrophysics Data System (ADS)

    Skinner, E. M. W.; Apter, D. B.; Morelli, C.; Smithson, N. K.

    2004-09-01

    The Man craton in West Africa is an Archaean craton formerly joined to the Guyana craton (South America) that was rifted apart in the Mesozoic. Kimberlites of the Man craton include three Jurassic-aged clusters in Guinea, two Jurassic-aged clusters in Sierra Leone, and in Liberia two clusters of unknown age and one Neoproterozoic cluster recently dated at ˜800 Ma. All of the kimberlites irrespective of age occur as small pipes and prolific dykes. Some of the Banankoro cluster pipes in Guinea, the Koidu pipes in Sierra Leone and small pipes in the Weasua cluster in Liberia contain hypabyssal-facies kimberlite and remnants of the so-called transitional-facies and diatreme-facies kimberlite. Most of the Man craton kimberlites are mineralogically classified as phlogopite kimberlites, although potassium contents are relatively low. They are chemically similar to mica-poor Group 1A Southern African examples. The Jurassic kimberlites are considered to represent one province of kimberlites that track from older bodies in Guinea (Droujba 153 Ma) to progressively younger kimberlites in Sierra Leone (Koidu, 146 Ma and Tongo, 140 Ma). The scarcity of diatreme-facies kimberlites relative to hypabyssal-facies kimberlites and the presence of the so-called transitional-facies indicate that the pipes have been eroded down to the interface between the root and diatreme zones. From this observation, it is concluded that extensive erosion (1-2 km) has occurred since the Jurassic. In addition to erosion, the presence of abundant early crystallizing phlogopite is considered to have had an effect on the relatively small sizes of the Man craton kimberlites.

    A number of medically oriented research and hardware development programs in support of manned space flights have been sponsored by NASA. Blood pressure measuring systems for use in spacecraft are considered. In some cases, complete new bioinstrumentation systems were necessary to accomplish a specific physiological study. Plans for medical research during the Skylab program are discussed along with general questions regarding space-borne health service systems and details concerning the Health Services Support Control Center.

  12. Manned Mars missions using propellant from space

    SciTech Connect

    Zuppero, A.C.; Olson, T.S. ); Redd, L.R. )

    1993-01-10

    .A recent discovery (8/14/92) of a near-earth object containing materials potentially useful for space activities could perhaps change the entire way humans access and operate in space. A near-Earth object ([number sign]4015, 1979 VA, comet Wilson-Harrington) contains water ice that could be used for space propulsion. In addition, this type of object may contain structural and lifesustaining materials (complex hydrocarbons, ammonia and/or bound nitrogen compounds) for space structures, manned planetary bases, or planetary surface terraforming. The retrieval and utilization of rocket propellant from near-Earth objects, for manned Mars missions in particular, has been investigated and the benefits of this scenario to over performing a Mars mission with terrestrial propellants have been documented. The results show water extracted from these objects and retrieved to Earth orbit for use in going to Mars may actually enable manned Mars exploration by reducing the number of Heavy Lift Launch Vehicle (HLLV) flights or eliminating the need for HLLV's altogether. The mission can perhaps be supported with existing launch vehicles and not required heavy lift capability. Also, the development of a nuclear thermal rocket for this alternate approach may be simplified substantially by reducing the operating temperature required.

  13. Freud, evolution, and the tragedy of man.

    PubMed

    Holmes, K R

    1983-01-01

    It is argued that Freud was not, as Sulloway (1979) contends, a "crypto-biologist" of the mind, but rather a cultural anthropologist of the mind. Freud's genetic conception of the psychic apparatus was neither exclusively nor critically derived from biology. Rather, it was based on an anthropogenetic approach to the archaic heritage of mind inspired in part by the moral philosophy of Nietzsche. The idea of tragedy was the unifying theme of Freud's cultural interpretation of evolutionary psychology. The historical search for the primal origins of neurosis led Freud to the unavoidable conclusion that neurosis was in the beginning a prehistoric moral dilemma which, over the course of mental evolution, eventually evolved into guilt, discontent, and neurosis as modern-day phylogenetically endowed facts of life. Freud (1930) made it clear that the source of man's biological and cultural evolutionary progress--self-denial--was also responsible for the tragedy of the human condition, namely, repression, eternal psychic ambivalence, and chronic mental illness. He believed that neurosis began, as Nietzsche (1887) exclaimed, with the "reduction of the beast of prey 'man' to a tame and civilized animal..." (p. 42). For both Freud and Nietzsche, the cause of the human tragedy was not merely the fall from Nature, but the inexorable knowledge that Man's denial of his biological heritage was the very basis for being human.

    A view of the facility and operational requirements involved in performing a manned thermal vacuum test is presented. The requirements fall into two major categories. The first category deals with placing the suited crewmen in a hazardous environment and assuring their safety. The second category deals with the constraints and special requirements involved with a suited crewman operating flight hardware in a 1-G environment. Design areas that deal with man rating a chamber, including fire suppression, emergency repress, emergency power, backups, reliable instrumentation and data systems, communications, television monitoring, biomedical monitoring, material compatibilities, and equipment supporting the Extravehicular Mobility Unit (EMU) are discussed. The operational issues that are peculiar to manned testing such as test rules, test procedures, test protocol, emergency drills, availability of hyperbaric facilities, test team training and certification engineering concerns for a safe mechanical and instrumentation buildup, hazard analysis, and Failure Modes and Effects Analysis are discussed. The constraints and special requirements involved with a suited crewman operating flight hardware in a 1-G environment are addressed.

    The Taurus Lightweight Manned Spacecraft (LMS) was developed by students of the University of Maryland's Aerospace Engineering course in Space Vehicle Design. That course required students to design an Alternative Manned Spacecraft (AMS) to augment or replace the Space Transportation System and meet the following design requirements: (1) launch on the Taurus Booster being developed by Orbital Sciences Corporation; (2) 99.9 percent assured crew survival rate; (3) technology cutoff data of 1 Jan. 1991; (4) compatibility with current space administration infrastructure; and (5) first flight by May 1995. The Taurus LMS design meets the above requirements and represents an initial step towards larger and more complex spacecraft. The Taurus LMS has a very limited application when compared to the Space Shuttle, but it demonstrates that the U.S. can have a safe, reliable, and low cost space system. The Taurus LMS is a short mission duration spacecraft designed to place one man into low earth orbit (LEO). The driving factor for this design was the low payload carrying capabilities of the Taurus Booster--1300 kg to a 300 km orbit. The Taurus LMS design is divided into six major design sections. The human factors system deals with the problems of life support and spacecraft cooling. The propulsion section contains the abort system, the Orbital Maneuvering System (OMS), the Reaction Control System (RCS), and power generation. The thermal protection systems and spacecraft structure are contained in the structures section. The avionics section includes navigation, attitude determination, data processing, communication systems, and sensors. The mission analysis section was responsible for ground processing and spacecraft astrodynamics. The systems integration section pulled the above sections together into one spacecraft and addressed costing and reliability.

  10. Man-caused seismicity of Kuzbas

    2009-04-01

    A natural seismicity of Kuznetsk Basin is confined in the main to mountain frame of Kuznetsk hollow. In this paper materials of experimental work with local station networks within sediment basin are presented. Two types of seismicity display within Kuznetsk hollow have been understood: first, man-caused seismic processes, confined to mine working and concentrated on depths up to one and a half of km; secondly, seismic activations on depths of 2-56 km, not coordinated in plan with coal mines. Every of studied seismic activations consists of large quantity of earthquakes of small powers (Ms=1-3). From one to first tens of earthquakes were recorded in a day. The earthquakes near mine working shift in space along with mine working, and seismic process become stronger at the instant a coal-plough machine is operated, and slacken at the instant the preventive works are executed. The seismic processes near three lavas in Kuznetsk Basin have been studied in detail. Uplift is the most typical focal mechanism. Activated zone near mine working reach in diameter 1-1,5 km. Seismic activations not linked with mine working testify that the subsoil of Kuznetsk hollow remain in stress state in whole. The most probable causes of man-caused action on hollow are processes, coupled with change of physical state of rocks at loss of methane from large volume or change by mine working of rock watering in large volume. In this case condensed rocks, lost gas and water, can press out upwards, realizing the reverse fault mechanism of earthquakes. A combination of stress state of hollow with man-caused action at deep mining account for activations nascent in Kuznetsk Basin. Today earthquakes happen mainly under mine workings, and damages of workings themselves do not register, but intensive shaking felt on surface calls for intent study of so dangerous phenomena.

    1984-01-01

    Although both the epidemiologic and experimental studies have led to the identification of chemical carcinogens, the limitations in epidemiologic approaches and the need for primary prevention of cancer require a greater reliance on experimental studies. Long-term carcinogenicity studies in experimental animals have been instrumental in identifying chemicals with carcinogenic activity, and, in some cases, the experimental evidence has preceded the epidemiologic evidence (for 4-aminobiphenyl, aflatoxin B1, diethylstilbestrol, melphalan, mustard gas, and vinyl chloride). A better understanding of the multistage process of carcinogenesis and the findings from various short-term tests available more recently may provide a more solid basis for extrapolating experimental findings to man.

    Clicks and other acoustic stimuli evoke time-locked responses from the brain of man. The properties of the waves recordable within the interval from 1 to 10 msec after the stimuli strike the eardrum are discussed along with factors influencing the waves in the 100 to 500 msec epoch. So-called brainstem responses from a normal young adult are considered. No waves were observed for clicks to weak to be heard. With increasing stimulus strength the waves become larger in amplitude and their latency shortens.

    Building manned lunar base is one of the core aims of human lunar exploration project, which is also an important way to carry out the exploitation and utilization of lunar in situ resources. The most important part of manned lunar base is the design and construction of living habitation and many factors should be considered including science objective and site selection. Through investigating and research, the scientific goals of manned lunar base should be status and characteristics ascertainment of lunar available in situ resources, then developing necessary scientific experiments and utilization of lunar in situ resources by using special environment conditions of lunar surface. The site selection strategy of manned lunar base should rely on scientific goals according to special lunar surface environment and engineering capacity constraints, meanwhile, consulting the landing sites of foreign unmanned and manned lunar exploration, and choosing different typical regions of lunar surface and analyzing the landform and physiognomy, reachability, thermal environment, sunlight condition, micro meteoroids protection and utilization of in situ resources, after these steps, a logical lunar living habitation site should be confirmed. This paper brings out and compares three kinds of configurations with fabricating processes of manned lunar base, including rigid module, flexible and construction module manned lunar base. 1.The rigid habitation module is usually made by metal materials. The design and fabrication may consult the experience of space station, hence with mature technique. Because this configuration cannot be folded or deployed, which not only afford limit working and living room for astronauts, but also needs repetitious cargo transit between earth and moon for lunar base extending. 2. The flexible module habitation can be folded in fairing while launching. When deploying on moon, the configuration can be inflatable or mechanically-deployed, which means under

    The literature dealing with the protection of man against rabies over the past 70 years in many parts of the world is reviewed, and the salient problems of our present state of knowledge analysed. The author discusses the measures currently in use for eliminating canine rabies by quarantine, regulation of the dog population, and—in particular—mass vaccination of dogs, with a detailed survey of the questions of immunological research which this method raises. Measures for suppressing the disease in other vectors are also described. It is concluded that, given effective education of the public and the widespread use of canine mass vaccination, human rabies is a preventable disease. PMID:13182607

    A one man inflatable life raft is described. The raft has an inflatable tube perimetrically bounding the occupant receiving space with a flexible floor member. A zippered opening in the floor allows entry and facilitates the use of a constant diameter tube. An airtight fabric bulkhead divides the peripheral tube longitudinally into inflatable tube sections, where if either tube section were punctured, the bulkhead would move into the punctured section to substitute for the punctured wall portion and maintain the inflatable volume of the tube. The floor member is attached to the central portion of the tube wall so that either side of the raft can be the up side.

    Inasmuch as orf, milker's nodules and bovine papular stomatitis pox are clinically identical in man and are induced by currently indistinguishable parapox viruses, we propose a new generic term 'farmyard pox' for these diseases. This affords the clinician a diagnosis based on a common set of clinical and electron microscopic findings rather than one based on an uncertain or even misleading history. A case in point is reported in which the history failed to reveal a specific animal source of the virus, but electron microscopy confirmed the presence of parapox infection.

    The kinetochore, located at the primary constriction or centromere in mammalian metaphase chromosomes, is the site of attachment of spindle microtubules to the mitotic chromosome, and is thus essential for correct chromosome movement and segregation at anaphase. Errors in organization of the kinetochore and/or centromere may therefore lead to non-disjunction and aneuploidy. The centromeres of most, if not all, mammalian chromosomes contain repetitive DNA sequences, which are observed at the cytogenetic level as heterochromatin. We have combined immunofluorescence with primed in situ hybridization (PRINS) techniques to study the organization of repetitive DNA families in relation to chromosomal proteins located at centromeres in both man and mouse species.

    A formidable challenge in modern respiratory healthcare is the accurate and timely diagnosis of lung infection and inflammation. The EPSRC Interdisciplinary Research Collaboration (IRC) `Proteus' seeks to address this challenge by developing an optical fibre based healthcare technology platform that combines physiological sensing with multiplexed optical molecular imaging. This technology will enable in situ measurements deep in the human lung allowing the assessment of tissue function and characterization of the unique signatures of pulmonary disease and is illustrated here with our in-man application of Optical Imaging SmartProbes and our first device Versicolour.

  6. Postural Control in Man: The Phylogenetic Perspective

    PubMed Central

    Gramsbergen, Albert

    Erect posture in man is a recent affordance from an evolutionary perspective. About eight million years ago, the stock from which modern humans derived split off from the ape family, and from around sixty-thousand years ago, modern man developed. Upright gait and manipulations while standing pose intricate cybernetic problems for postural control. The trunk, having an older evolutionary history than the extremities, is innervated by medially descending motor systems and extremity muscles by the more recent, laterally descending systems. Movements obviously require concerted actions from both systems. Research in rats has demonstrated the interdependencies between postural control and the development of fluent walking. Only 15 days after birth, adult-like fluent locomotion emerges and is critically dependent upon postural development. Vesttibular deprivation induces a retardation in postural development and, consequently, a retarded development of adult-like locomotion. The cerebellum obviously has an important role in mutual adjustments in postural control and extremity movements, or, in coupling the phyiogenetic older and newer structures. In the human, the cerebellum develops partly after birth and therefore is vulnerable to adverse perinatal influences. Such vulnerability seems to justify focusing our scientific research efforts onto the development of this structure. PMID:16097476

    1992-01-01

    GridMan is an interactive grid manipulation system. It operates on grids to produce new grids which conform to user demands. The input grids are not constrained to come from any particular source. They may be generated by algebraic methods, elliptic methods, hyperbolic methods, parabolic methods, or some combination of methods. The methods are included in the various available structured grid generation codes. These codes perform the basic assembly function for the various elements of the initial grid. For block structured grids, the assembly can be quite complex due to a large number of clock corners, edges, and faces for which various connections and orientations must be properly identified. The grid generation codes are distinguished among themselves by their balance between interactive and automatic actions and by their modest variations in control. The basic form of GridMan provides a much more substantial level of grid control and will take its input from any of the structured grid generation codes. The communication link to the outside codes is a data file which contains the grid or section of grid.

    Fourteen monogenic cutaneous disorders of man are compared to similar gene defects in animals. The traits are classified into two groups. In the first group, an identity (homology) of the underlying gene defects is likely. This group includes oculo-cutaneous albinism, Chédiak-Higashi syndrome, aplasia cutis congenita, Ehlers-Danlos syndrome (type I), hypohidrotic ectodermal dysplasia of the Christ-Siemens-Touraine type, X-linked dominant chondrodysplasia punctata, ichthyosis congenita gravis, Menkes syndrome, erythropoetic porphyria, porphyria cutanea tarda, and acrodermatitis enteropathica. In the second group, the traits are similar but the question of their homology cannot be settled. It includes alopecia congenita, hidrotic ectodermal dysplasia of the Clouston type, and hereditary lymphedema. The existence of identical mutations in man and animals provides evidence for the close relationship between the various mammalian species. Homologous traits affecting the skin are of practical importance since the use of these animal models may help to answer those questions which cannot be answered by performing research in human patients.

    1990-01-01

    The United States is in trouble in space. The costs of the proposed Space Station Freedom have grown beyond reach, and the present design is obsolete. The trouble has come from imagining that there are only two alternatives: manned vs. unmanned. Both choices have led us into designs that do not appear to be practical. On one side, the United States simply does not possess the robotic technology needed to operate or assemble a sophisticated unmanned space station. On the other side, the manned designs that are now under way seem far too costly and dangerous, with all of its thousands of extravehicular activity (EVA) hours. More would be accomplished at far less cost by proceeding in a different way. The design of a space station made of modular, Erector Set-like parts is proposed which is to be assembled using earth-based remotely-controlled binary-tree telerobots. Earth-based workers could be trained to build the station in space using simulators. A small preassembled spacecraft would be launched with a few telerobots, and then, telerobots could be ferried into orbit along with stocks of additional parts. Trained terrestrial workers would remotely assemble a larger station, and materials for additional power and life support systems could be launched. Finally, human scientists and explorers could be sent to the space station. Other aspects of such a space station program are discussed.

    2015-04-01

    Stiff Man syndrome or stiff-person syndrome is a rare autoimmune disorder. It is characterized by increased axial muscular tone and limb musculature, and painful spasms triggered by stimulus. The case is presented of a 44-year-old man with stiff-person syndrome undergoing an injection of botulinum toxin in the urethral sphincter under sedation. Before induction, all the surgical team were ready in order to minimise the anaesthetic time. The patient was monitored by continuous ECG, SpO2 and non-invasive blood pressure. He was induced with fractional dose of propofol 150 mg, fentanyl 50 μg and midazolam 1mg. Despite careful titration, the patient had an O2 saturation level of 90%,which was resolved by manual ventilation. There was no muscle rigidity or spasm during the operation. Post-operative recovery was uneventful and the patient was discharged 2 days later. A review of other cases is presented. The anaesthetic concern in patients with stiff-person syndrome is the interaction between the anaesthetic agents, the preoperative medication, and the GABA system. For a safe anaesthetic management, total intravenous anaesthesia is recommended instead of inhalation anaesthetics, as well as the close monitoring of the respiratory function and the application of the electrical nerve stimulator when neuromuscular blockers are used.

  14. Integrated shielding systems for manned interplanetary spaceflight

    George, Jeffrey A.

    1992-01-01

    The radiation environment encountered by manned interplanetary missions can have a severe impact on both vehicle design and mission performance. This study investigates the potential impact of radiation protection on interplanetary vehicle design for a manned Mars mission. A systems approach was used to investigate the radiation protection requirements of the sum interplanetary environment. Radiation budgets were developed which result in minimum integrated shielding system masses for both nuclear and non-nuclear powered missions. A variety of system configurations and geometries were assessed over a range of dose constraints. For an annual dose equivalent rate limit of 50 rem/yr, an environmental shielding system composed of a habitat shield and storm shelter was found to result in the lowest total mass. For a limit of 65 rem/yr, a system composed of a sleeping quarters shield was least massive, and resulted in significantly reduced system mass. At a limit of 75 rem/yr, a storm shelter alone was found to be sufficient, and exhibited a further mass reduction. Optimal shielding system results for 10 MWe nuclear powered missions were found to follow along similar lines, with the addition of a reactor shadow shield. A solar minimum galactic cosmic ray spectrum and one anomalously large solar particle event during the course of a two year mission were assumed. Water was assumed for environmental radiation shielding.

    Men in the United States are products of society's assumptions about what it means to "be a man." Throughout American history, these assumptions have supported aggression, conflict, and war. Seeing American troops in Iraq conjures comparisons not only to past military ventures but also to the changing face of the masculine warrior. One might see…

    2013-12-01

    A 73-year-old, previously healthy man presented with nausea, vomiting, diarrhea, dry mouth and febrile sensation 3 hours after eating boiled wild mushrooms. After admission, he showed progressive severe respiratory distress, pancytopenia, azotemia, hypotension, hypoxemia and consolidation of the entire left lung on chest radiography. With a preliminary diagnosis of necrotizing pneumonia, he underwent left pneumonectomy in order to remove all necrotic lung tissue. Lung histology showed extensive hemorrhagic necrosis, massive inflammatory cell infiltration, prominent proliferation of young fibroblasts and the formation of an early-stage hyaline membrane along the alveolar wall. Despite aggressive treatment, including mechanical ventilation, continuous renal replacement therapy and administration of granulocyte colony stimulating factor and broad spectrum antibiotics, he died on hospitalization day 13. Subsequently, the mushroom was identified as Podostroma cornu-damae. This is the first case of a histological evidence of lung involvement by Podostroma cornu-damae poisoning in Korea.

  19. Hepatocellular carcinoma in a young man with resting and postural tremors.

    Waqar, Mueez; Vohra, Anjum Habib

    2013-09-30

    A 25-year-old man who was normally fit and well, presented with a 2-year history of progressively worsening tremor. His tremor was generalised, affecting head, neck and all four limbs. One of the patient's brothers had suffered from similar problems, but never sought medical attention. Examination revealed a generalised tremor, of greater amplitude on the patient's left side, which increased in its amplitude upon exertion. Slit-lamp examination revealed bilateral Kayser-Fleischer rings and serum caeruloplasmin was found to be low, while 24 h urinary copper excretion was elevated. A diagnosis of Wilson's disease was made and an abdominal ultrasound was performed, revealing evidence of portal hypertension and a hyperechoic hepatic nodule, later confirmed to be hepatocellular carcinoma. The patient underwent partial hepatic resection and was started on D-penicillamine.

    2007-01-01

    A 20-year-old man presented to an emergency department with dramatic, sudden-onset, tearing chest pain. He also claimed to have been previously diagnosed with Ehler-Danlos syndrome and a previous Type I aortic dissection (intimal tear of ascending aorta), rapidly increasing his treating physician's suspicion of an emergent aortic dissection. The patient was quickly transferred to a large university hospital, where he underwent a median sternotomy and thoracotomy, with no aortic pathology found on operation and biopsy. After the patient's postoperative recovery, he was treated at a mental health facility, where he remained ambivalent about his psychiatric condition and did not respond well to treatment. This case report describes a unique case of factitious disorder that led to a serious operative intervention and subsequent psychiatric care and assesses factors that might have contributed to his hospital course.

  1. Man/computer communication in a space environment

    Hodges, B. C.; Montoya, G.

    1973-01-01

    The present work reports on a study of the technology required to advance the state of the art in man/machine communications. The study involved the development and demonstration of both hardware and software to effectively implement man/computer interactive channels of communication. While tactile and visual man/computer communications equipment are standard methods of interaction with machines, man's speech is a natural media for inquiry and control. As part of this study, a word recognition unit was developed capable of recognizing a minimum of one hundred different words or sentences in any one of the currently used conversational languages. The study has proven that efficiency in communication between man and computer can be achieved when the vocabulary to be used is structured in a manner compatible with the rigid communication requirements of the machine while at the same time responsive to the informational needs of the man.

  2. Design and finite element analysis of oval man way

    SciTech Connect

    Hari, Y.; Gryder, B.

    1996-12-01

    This paper presents the design of an oval man way in the side wall of a cylindrical pressure vessel. ASME Code Section 8 is used to obtain the design parameters of the oval man way, man way cover and bolts. The code calculations require some assumptions which may not be valid. A typical design example is taken. STAAD III finite element code with plate elements is used to model the oval man way, man way cover and bolts. The stresses calculated using ASME Code Section 8 and other analytical formulas for plate and shells are compared with the stresses obtained by Finite Element Modeling. This paper gives the designer of oval man way the ability to perform a finite element analysis and compare it with the analytical calculations and assumptions made. This gives added confidence to the designer as to the validity of his calculations and assumptions.

    The Calysto: Risk Management for Commercial Manned Spaceflight study analyzes risk management in large enterprises and how to effectively communicate risks across organizations. The Calysto Risk Management tool developed by NASA's Kennedy Space Center's SharePoint team is used and referenced throughout the study. Calysto is a web-base tool built on Microsoft's SharePoint platform. The risk management process at NASA is examined and incorporated in the study. Using risk management standards from industry and specific organizations at the Kennedy Space Center, three methods of communicating and elevating risk are examined. Each method describes details of the effectiveness and plausibility of using the method in the Calysto Risk Management Tool. At the end of the study suggestions are made for future renditions of Calysto.

    Sir Frederick Treves first showed Joseph Merrick, the famous Elephant Man, to the Pathological Society of London in 1884. A diagnosis of neurofibromatosis was suggested in 1909 and was widely accepted. There is no evidence, however, of café au lait spots or histological proof of neurofibromas. It is also clear that Joseph Merrick's manifestations were much more bizarre than those commonly seen in neurofibromatosis. Evidence indicates that Merrick suffered from the Proteus syndrome and had the following features compatible with this diagnosis: macrocephaly; hyperostosis of the skull; hypertrophy of long bones; and thickened skin and subcutaneous tissues, particularly of the hands and feet, including plantar hyperplasia, lipomas, and other unspecified subcutaneous masses.

  7. Rover technology for manned Mars missions

    NASA Technical Reports Server (NTRS)

    Klein, Gail

    1986-01-01

    A set of roving vehicle design requirements were postulated, corresponding to an idealized Mars transport vehicle operational scenario which could serve as a reference for a manned Mars mission. The ability of conventional vehicles to satisfy these requirements were examined. The study indicated that no conventional vehicle could satisfy all of the requirements, as the vehicles are presently configured. Consequently, the requirements have to either be relaxed and/or an alternative, less conventional vehicle design will have to be developed. A possible unconventional vehicle design which has received considerable attention for DARPA and the Army is the walker vehicle. The design issues associated with this vehicle are presented, along with a comparison of the performance capabilities of this technology vs. conventional vehicle technology.

  8. Urinary Excretion of Antidiuretic Hormone in Man

    NASA Technical Reports Server (NTRS)

    Miller, M.

    1972-01-01

    It is shown that urinary excretion of ADH can be detected readily and quantitated accurately. The ADH excretion in normal subjects is inhibited following the administration of a water load and stimulated following water deprivation. It appears that measurement of ADH excretion in man provides a means of quantitating alterations in neurohypophyseal ADH secretion. By determining not only the basal excretion of ADH but also the response to such physiological influences as water loading and dehydration, it becomes possible to study the dynamics of ADH release. Thus, the ability to extract ADH efficiently from urine combined with a sensitive and specific technique for determination of ADH concentration allows the exploration of regulatory systems for ADH control in the normal state as well as the etiological role of altered ADH secretion in clinical disorders of water balance.

  9. Quetelet, the average man and medical knowledge.

    PubMed

    Caponi, Sandra

    2013-01-01

    Using two books by Adolphe Quetelet, I analyze his theory of the 'average man', which associates biological and social normality with the frequency with which certain characteristics appear in a population. The books are Sur l'homme et le développement de ses facultés and Du systeme social et des lois qui le régissent. Both reveal that Quetelet's ideas are permeated by explanatory strategies drawn from physics and astronomy, and also by discursive strategies drawn from theology and religion. The stability of the mean as opposed to the dispersion of individual characteristics and events provided the basis for the use of statistics in social sciences and medicine.

    Danon disease is a rare, codominant X-linked genetic disorder characterized by the triad of left ventricular hypertrophy, mental retardation, and peripheral myopathy. This disease is caused by mutations in the gene that encodes lysosomal associated membrane protein 2 (LAMP2), a deficiency of which results in the accumulation of autophagic granular débris within the vacuoles of muscle cells. This is a report of an asymptomatic 19-year-old man with Danon disease in the absence of mental retardation or clinically significant skeletal myopathy. This case underscores the importance of accurate diagnosis of unexplained left ventricular hypertrophy, in order to establish an appropriate treatment plan and to advise genetic counseling.

  12. Manned remote work station development article

    NASA Technical Reports Server (NTRS)

    1978-01-01

    The two prime objectives of the Manned Remote Work Station (MRWS) Development Article Study are to first, evaluate the MRWS flight article roles and associated design concepts for fundamental requirements and embody key technology developments into a simulation program; and to provide detail manufacturing drawings and schedules for a simulator development test article. An approach is outlined which establishes flight article requirements based on past studies of Solar Power Satellite, orbital construction support equipments, construction bases and near term shuttle operations. Simulation objectives are established for those technology issues that can best be addressed on a simulator. Concepts for full-scale and sub-scale simulators are then studied to establish an overall approach to studying MRWS requirements. Emphasis then shifts to design and specification of a full-scale development test article.

  13. Earth orbital operations supporting manned interplanetary missions

    Sherwood, Brent; Buddington, Patricia A.; Whittaker, William L.

    1989-01-01

    The orbital operations required to accumulate, assemble, test, verify, maintain, and launch complex manned space systems on interplanetary missions from earth orbit are as vital as the flight hardware itself. Vast numbers of orbital crew are neither necessary nor desirable for accomplishing the required tasks. A suite of robotic techniques under human supervisory control, relying on sensors, software and manipulators either currently emergent or already applied in terrestrial settings, can make the job tractable. The mission vehicle becomes largely self-assembling, using its own rigid aerobrake as a work platform. The Space Station, having been used as a laboratory testbed and to house an assembly crew of four, is not dominated by the process. A feasible development schedule, if begun soon, could emplace orbital support technologies for exploration missions in time for a 2004 first interplanetary launch.

    Goudie, A.

    1982-01-01

    Drawing upon worldwide examples, the author traces mankind's interaction with nature and examines human interference with environmental systems at various stages of social development. Succeeding chapters take up man's specific impact on vegetation, animals, the soil, the waters, landforms, climate, and the atmosphere. With the aid of maps, diagrams, and graphs, the book analyzes the causes and consequences of environmental changes associated with such large-scale events as agricultural expansion, domestication, deforestation, and urbanization, including the spread of salination, extinction, erosion, and pollution. Interrelations, often dynamic and unpredictable, between these phenomena make it difficult to isolate the causes of changes and to determine the resiliency of natural systems to change. 505 references, 82 figures, 97 tables.

    Methods involved in and results obtained with a new comprehensive ataxia test battery are described, and definitions of spontaneous and induced vestibular ataxia in man are given in terms of these findings. In addition, the topic of alcohol-induced ataxia in relation to labyrinth function is investigated. Items in the test battery comprise a sharpened Romberg test, in which the subject stands on the floor with eyes closed and arms folded against his chest, feet heel-to-toe, for 60 seconds; an eyes-open walking test; an eyes-open standing test; an eyes-closed standing test; an eyes-closed on-leg standing test; an eyes-closed walk a line test; an eyes-closed heel-to-toe walking test; and supplementary ataxia tests such as the classical Romberg test.

    Boyland, R. E.; Kline, R. L.

    1981-01-01

    From a study that identified over 100 possible geosynchronous orbit-related applications for manned orbit transfer vehicles (MOTV), a group of 20 are chosen for consideration. These generic missions can be grouped into five categories: (1) inspection service and repair, (2) operation of large systems, (3) debris removal, (4) construction, and (5) unmanned cargo. Among the findings of this study is that space basing permits more efficient use of Space Shuttle flights, since the core propulsion system, crew cabin and general purpose mission hardware need not be launched into space each time. A conservative traffic model shows that $600 million may be saved over five years by space basing, due to the decreased number of Shuttle flights needed to support the space-based MOTV. Crew information, payloads, characteristics of the vehicle, and mission requirements are covered in detail.

    1992-08-01

    A two-stage fully reusable rocked powered concept is defined and analyzed in detail for the Advanced Manned Launch System missions. The concept elements include a Mach 3 staging unmanned glideback booster and a 149-ft long winged orbiter with an external payload canister with a 15-ft diameter and 30-ft long payload bay. The booster and orbiter main propulsion system is a lightweight derivative of the current Space Shuttle Main Engine. The primary mission is the Space Station Freedom logistics mission, 40,000-lb payload with two crew members and eight passengers. The structural design and material selection, the thermal protection system, the integral cryogenic tanks and insulation, the propulsion system, and the modular payload canister system are described. The ground and flight operations approach analysis, the manufacturing and certification plan, and the technology development requirements are also discussed.

    PubMed

    Stolkowski, J; Choukroun, J

    1981-11-01

    The determination of sex is influenced by ionic factors. In man, ionic imbalance is responsible for the sex ratio in at least 80% of cases, the possible mechanism being one of selective fertilization. These facts constitute the scientific basis for the medicodietary method of selecting sex. The intervention of ions in ovarian metabolism is obtained by controlling the diet of the woman, the decisive factor being the ratio of K+ + Na+ to Ca2+ + Mg2+ in the daily diet. High values of this ratio lead to boys, and low values to girls. Using this method since 1970 in 47 births, only 7 of them failed to produce the expected sex. The interactions and the causes of failure are analyzed.

    1995-06-01

    Classical mechanics is based upon a mechanical picture of nature that is fundamentally incorrect. It has been replaced at the basic level by a radically different theory: quantum mechanics. This change entails an enormous shift in one`s basic conception of nature, one that can profoundly alter the scientific image of man himself. Self-image is the foundation of values, and the replacement of the mechanistic self-image derived from classical mechanics by one concordant with quantum mechanics may provide the foundation of a moral order better suited to today`s times, a self-image that endows human life with meaning, responsibility, and a deeper linkage to nature as a whole.

  20. Boscovich: scientist and man of letters

    NASA Astrophysics Data System (ADS)

    Proverbio, E.

    Ruggiero Giuseppe Boscovich (1711-1781) is known as one of the most important scientists of the second half of XVIII century, but he was active also as a man of letters, especially through an abundant production of poems in Latin verse. We try to interpret these two, apparently antinomic, aspects of his character in the framework of the culture of his epoch, in which science and literary productions were not considered as two separate or opposite fields, but only two different aspects of human knowledge. In particular we review the field of his poetic production in which this fundamental unity of knowledge is most evident, namely his poems with didactic-scientific subjects, which are examples of high-level popularization of the latest progresses in science (in particular astronomy and Newtonian physics) by means of elegant Latin verse.

  1. [Hemoptysis in a young man smoking cannabis].

    Monfort, M; Larakeb, A; Gouraud, F

    2013-06-01

    The respiratory toxicity of cannabis is well known today. Along with the classic cannabis 'joint', there are other ways of consuming it, which should be known. Smoking cannabis that has been cut with micro-particles of silicon dioxide may cause hemoptysis. We will describe here the case of a young 16-year-old man who was in the hospital because of hemoptic expectoration. The etiologic investigation was negative, in particular a thoracic scan and a bronchial fiberscope. Questioning the patient afterwards allowed us to discover the inhalation of cannabis 2 h before the hemoptysis, cannabis mixed with micro-particles of silicon dioxide. Stopping inhalation stopped the symptoms. Pediatricians should be familiarized with such practices. Silicon dioxide particles cause ENT problems or bronchial ones (coughing, spitting, hemoptysis, wheezing). Over the long term, the risk of silicosis cannot be excluded, although a longer and more complete exposure is necessary.

  2. Biomedical support of man in space

    NASA Astrophysics Data System (ADS)

    Pendergast, D. R.; Olszowka, A. J.; Rokitka, M. A.; Farhi, L. E.

    In its broadest sense, biomedical support of man in space must not be limited to assisting spacecraft crew during the mission; such support should also ensure that flight personnel be able to perform properly during landing and after leaving the craft. Man has developed mechanisms that allow him to cope with specific stresses in his normal habitat; there is indisputable evidence that, in some cases, the space environment, by relieving these stresses, has also allowed the adaptive mechanisms to lapse, causing serious problems after re-entry. Inflight biomedical support must therefore include means to simulate some of the normal stresses of the Earth environment. In the area of cardiovascular performance, we have come to rely heavily on complex feedback mechanisms to cope with two stresses, often combined: postural changes, which alter the body axis along which gravitational acceleration acts, and physical exercise, which increases the total load on the system. Unless the appropriate responses are reinforced continuously during flight, crew members may be incapacitated upon return. The first step in the support process must be a study of the way in which changes in g, even of short duration, affect these responses. In particular we should learn more about effects of g on the "on" and "off" dynamics, using a variety of approaches: increased acceleration on one hand at recumbency, immersion, lower body positive pressure, and other means of simulating some of the effects of low g, on the other. Once we understand this, we will have to determine the minimal exposure dose required to maintain the response mechanisms. Finally, we shall have to design stresses that simulate Earth environment and can be imposed in the space vehicle. Some of the information is already at hand; we know that several aspects of the response to exercise are affected by posture.

    We report here the case of a young man suffering from a rare germ cell tumour. The patient was a 25-year-old man who was referred to our centre for asthenia, stinging epigastric pain, and an iron deficiency anaemia. Gastroscopy revealed a circumferential vegetating lesion on the second portion of the duodenum. The lesion was indurated at the third portion of the duodenum, responsible for a tight stenosis. A computerized tomography-scan of the chest, abdomen and pelvis, and a pancreatic MRI showed a circumferential lesion with a bi-ductal dilatation (i.e., of the common bile duct and Wirsung’s duct) without metastatic localisation. The patient underwent a pancreaticoduodenectomy with lymph node dissection including all cellular adipose tissues of the hepatic pedicle from the hepatic common artery and of the retroportal lamina. Histological findings were suggestive of a duodenal embryonal carcinoma with pancreatic infiltration. This is the second published case highlighting the duodenal primitive localisation of an embryonal carcinoma with pancreatic infiltration. PMID:28216981

  14. NASA Laboratory Analysis for Manned Exploration Missions

    The Exploration Laboratory Analysis (ELA) project supports the Exploration Medical Capability Element under the NASA Human Research Program. ELA instrumentation is identified as an essential capability for future exploration missions to diagnose and treat evidence-based medical conditions. However, mission architecture limits the medical equipment, consumables, and procedures that will be available to treat medical conditions during human exploration missions. Allocated resources such as mass, power, volume, and crew time must be used efficiently to optimize the delivery of in-flight medical care. Although commercial instruments can provide the blood and urine based measurements required for exploration missions, these commercial-off-the-shelf devices are prohibitive for deployment in the space environment. The objective of the ELA project is to close the technology gap of current minimally invasive laboratory capabilities and analytical measurements in a manner that the mission architecture constraints impose on exploration missions. Besides micro gravity and radiation tolerances, other principal issues that generally fail to meet NASA requirements include excessive mass, volume, power and consumables, and nominal reagent shelf-life. Though manned exploration missions will not occur for nearly a decade, NASA has already taken strides towards meeting the development of ELA medical diagnostics by developing mission requirements and concepts of operations that are coupled with strategic investments and partnerships towards meeting these challenges. This paper focuses on the remote environment, its challenges, biomedical diagnostics requirements and candidate technologies that may lead to successful blood/urine chemistry and biomolecular measurements in future space exploration missions. SUMMARY The NASA Exploration Laboratory Analysis project seeks to develop capability to diagnose anticipated space exploration medical conditions on future manned missions. To achieve

  15. Operational Philosophy Concerning Manned Spacecraft Cabin Leaks

    NASA Technical Reports Server (NTRS)

    DeSimpelaere, Edward

    2011-01-01

    The last thirty years have seen the Space Shuttle as the prime United States spacecraft for manned spaceflight missions. Many lessons have been learned about spacecraft design and operation throughout these years. Over the next few decades, a large increase of manned spaceflight in the commercial sector is expected. This will result in the exposure of commercial crews and passengers to many of the same risks crews of the Space Shuttle have encountered. One of the more dire situations that can be encountered is the loss of pressure in the habitable volume of the spacecraft during on orbit operations. This is referred to as a cabin leak. This paper seeks to establish a general cabin leak response philosophy with the intent of educating future spacecraft designers and operators. After establishing a relative definition for a cabin leak, the paper covers general descriptions of detection equipment, detection methods, and general operational methods for management of a cabin leak. Subsequently, all these items are addressed from the perspective of the Space Shuttle Program, as this will be of the most value to future spacecraft due to similar operating profiles. Emphasis here is placed upon why and how these methods and philosophies have evolved to meet the Space Shuttle s needs. This includes the core ideas of: considerations of maintaining higher cabin pressures vs. lower cabin pressures, the pros and cons of a system designed to feed the leak with gas from pressurized tanks vs. using pressure suits to protect against lower cabin pressures, timeline and consumables constraints, re-entry considerations with leaks of unknown origin, and the impact the International Space Station (ISS) has had to the standard Space Shuttle cabin leak response philosophy. This last item in itself includes: procedural management differences, hardware considerations, additional capabilities due to the presence of the ISS and its resource, and ISS docking/undocking considerations with a

  15. Antibodies against Manα1,2-Manα1,2-Man oligosaccharide structures recognize envelope glycoproteins from HIV-1 and SIV strains

    PubMed Central

    Luallen, Robert J; Agrawal-Gamse, Caroline; Fu, Hu; Smith, David F; Doms, Robert W; Geng, Yu

    2010-01-01

    Design of an envelope glycoprotein (Env)-based vaccine against human immunodeficiency virus type-1 (HIV-1) is complicated by the large number of N-linked glycans that coat the protein and serve as a barrier to antibody-mediated neutralization. Compared to normal mammalian glycoproteins, high-mannose-type glycans are disproportionately represented on the gp120 subunit of Env. These N-glycans serve as a target for a number of anti-HIV molecules that bind terminal α1,2-linked mannose residues, including lectins and the monoclonal antibody 2G12. We created a Saccharomyces cerevisiae glycosylation mutant, Δmnn1Δmnn4, to expose numerous terminal Manα1,2-Man residues on endogenous hypermannosylated glycoproteins in the yeast cell wall. Immunization of rabbits with whole cells from this mutant induced antibodies that bound to a broad range of Env proteins, including clade A, B, and C of HIV and simian immunodeficiency virus (SIV). The gp120 binding activity of these immune sera was due to mannose-specific immunoglobulin, as removal of high-mannose glycans and α1,2-linked mannoses from gp120 abrogated serum binding. Glycan array analysis with purified IgG demonstrated binding mainly to glycans with Manα1,2-Manα1,2-Man trisaccharides. Altogether, these data demonstrate the immunogenicity of exposed polyvalent Manα1,2-Manα1,2-Man structures on the yeast cell wall mannan and their ability to induce antibodies that bind to the HIV Env protein. The yeast strain and sera from this study will be useful tools for determining the type of mannose-specific response that is needed to develop neutralizing antibodies to the glycan shield of HIV.

  16. Estimation of dose to man from environmental tritium

    SciTech Connect

    Rohwer, P S; Etnier, E L

    1980-01-01

    Factors important for characterization of tritium in environmental pathways leading to exposure of man are reviewed and quantification of those factors is discussed. Parameters characterizing the behavior of tritium in man are also subjected to review. Factors to be discussed include organic binding, bioaccumulation, quality factor and transmutation. A variety of models are presently in use to estimate dose to man from environmental releases of tritium. Results from four representative models are compared and discussed. Site-specific information is always preferable when parameterizing models to estimate dose to man. There may be significant differences in dose potential among geographic regions due to variable factors. An example of one such factor examined is absolute humidity. It is concluded that adequate methodologies exist for estimation of dose to man from environmental tritium although a number of areas are identified where additional tritium research is desirable.

  17. Modelling an infrared Man Portable Air Defence System

    NASA Astrophysics Data System (ADS)

    Birchenall, Richard P.; Richardson, Mark A.; Brian, Butters; Roy, Walmsley

    2010-09-01

    The global proliferation of shoulder launched IR Man Portable Air Defence Systems (ManPADS) has resulted in the existence of a serious threat to both civilian and military aircraft from terrorist attack. Some of the older generations of ManPADS can be defeated with modern countermeasures but even the most sophisticated protection still has vulnerabilities to the latest family of ManPADS. This paper describes the work undertaken by the authors to model a second generation ManPAD, based on the Russian SA-14, and assess the vulnerabilities of aircraft both with and without flare countermeasures from these systems. The conclusions are the results of over 11,000 simulated firings against targets of varying aspects, velocities and altitudes.

  18. Orthostatic vasomotor response in spinal man.

    PubMed

    Krebs, M; Ragnarrson, K T; Tuckman, J

    1983-04-01

    The cardiovascular adaptation of tetraplegics to the upright position has been previously demonstrated to be deficient. Presumably this is due to the interruption of the spinal pathways linking supraspinal control centres with the peripheral sympathetic motor neurons. Review of previous studies of this phenomenon reveals that vasomotor responses have been determined primarily from blood flow measurements in the extremities. Contradictory conclusions have been drawn. Study of the visceral circulation, in particular renal blood flow, could shed more light on this poorly understood area. Renal clearance tests were carried out on seven healthy controls and eight chronic, clinically complete tetraplegic patients. Renal blood flow, mean arterial pressure, and total renal vascular resistance in both supine and passive head-up tilt positions were calculated from collected data. Renal blood flow and total renal vascular resistance showed significant decrease and increase respectively during tilting in controls and tetraplegic subjects. Although the renal circulation is autoregulated, postural change causes profound alteration of the renal blood flow mediated through the haemodynamic effects of the renal nerves. Sympathetic renal vasoconstriction is mediated by the carotid sinus reflex through the vasomotor centre in the brainstem. In the absence of supraspinal influence the renal vasculature is shown to respond to an orthostatic stimulus with a vigorous vasoconstriction. The adaptation of spinal man to the upright position may involve the recovery of a spinal vasomotor reflex involving the splanchnic circulation.

The landing vehicles are considered in two categories: those having essentially vertical-descent paths, the parachute-supported vehicles, and those having essentially horizontal paths, the lifting vehicles. The energy-dissipation devices discussed are crushable materials such as foamed plastics and honeycomb for internal application in couch-support systems, yielding metal elements as part of the structure of capsules or as alternates for oleos in landing-gear struts, inflatable bags, braking rockets, and shaped surfaces for water impact. It appears feasible to readily evaluate landing-gear systems for internal or external application in hard-surface or water landings by using computational procedures and free-body landing techniques with dynamic models. The systems investigated have shown very interesting energy-dissipation characteristics over a considerable range of landing parameters. Acceptable gear can be developed along lines similar to those presented if stroke requirements and human-tolerance limits are considered.

    The Exploration Laboratory Analysis (ELA) project supports the Exploration Medical Capability Element under the NASA Human Research Program. ELA instrumentation is identified as an essential capability for future exploration missions to diagnose and treat evidence-based medical conditions. However, mission architecture limits the medical equipment, consumables, and procedures that will be available to treat medical conditions during human exploration missions. Allocated resources such as mass, power, volume, and crew time must be used efficiently to optimize the delivery of in-flight medical care. Although commercial instruments can provide the blood and urine based measurements required for exploration missions, these commercial-off-the-shelf devices are prohibitive for deployment in the space environment. The objective of the ELA project is to close the technology gap of current minimally invasive laboratory capabilities and analytical measurements in a manner that the mission architecture constraints impose on exploration missions. Besides micro gravity and radiation tolerances, other principal issues that generally fail to meet NASA requirements include excessive mass, volume, power and consumables, and nominal reagent shelf-life. Though manned exploration missions will not occur for nearly a decade, NASA has already taken strides towards meeting the development of ELA medical diagnostics by developing mission requirements and concepts of operations that are coupled with strategic investments and partnerships towards meeting these challenges. This paper focuses on the remote environment, its challenges, biomedical diagnostics requirements and candidate technologies that may lead to successful blood-urine chemistry and biomolecular measurements in future space exploration missions.

    Studies were conducted on 15 healthy young soldiers to evaluate the effect of a cold acclimatization schedule on the thermoregulatory and metabolic activity on exposure to acute cold stress. These men were exposed to cold (10‡C) for 4 h daily wearing only shorts for 21 days, in a cold chamber. They were subjected to a standard cold test at 10 ± 1‡C the day 1, 6, 11 and 21. The subjects were made to relax in a thermoneutral room (26 28‡C) for 1 h and their heart rate, blood pressure, oxygen consumption, oral temperature, mean skin temperature, mean body temperature, peripheral temperatures, and shivering activity were recorded. Then they were exposed to 10‡C and measurements were repeated at 30 min intervals, for 2 h. The cold induced vasodilatation (CIVD), cold pressor response and thermoregulatory efficiency tests were measured initially and at the end of acclimatization schedule. The data show that the procedure resulted in elevated resting metabolism, less fall in body temperature during acute cold stress, reduction in shivering, improvement in CIVD and thermoregulatory efficiency and less rise in BP and HR during cold pressor response. The data suggest the possibility of cold acclimatization in man by repeated exposure to moderately severe cold stress.

    Teleoperation experiments at JPL have shown that advanced features in a telerobotic system are a necessary condition for good results, but that they are not sufficient to assure consistently good performance by the operators. Two or three operators are normally used during training and experiments to maintain the desired performance. An alternative to this multi-operator control station is a man-machine interface embedding computer programs that can perform some of the operator's functions. In this paper we present our first experiments with these concepts, in which we focused on the areas of real-time task monitoring and interactive path planning. In the first case, when performing a known task, the operator has an automatic aid for setting control parameters and camera views. In the second case, an interactive path planner will rank different path alternatives so that the operator will make the correct control decision. The monitoring function has been implemented with a neural network doing the real-time task segmentation. The interactive path planner was implemented for redundant manipulators to specify arm configurations across the desired path and satisfy geometric, task, and performance constraints.

    Approximately 2 million people die each year from tuberculosis. One third of the world´s population is estimated to be infected with the tuberculosis bacillus, although only 5-10% will develop the disease in their lifetime. The disease progression risk depends on endogenous and exogenous factors. Indigenous communities are a high-risk group for infection and development of tuberculosis. In addition to factors such as geographical isolation, social and cultural neglect and malnutrition, susceptibility to genetic polymorphisms has been identified in them. Spinal tuberculosis is the most destructive form of the disease, which represents approximately half of all cases of skeletal tuberculosis. The case of an HIV negative, indigenous Colombian man is presented. His diagnosis was done based on clinical and image findings, and it was confirmed with the rapid molecular assay Genotype MTBDRplus® and IS6110 PCR.The culture in solid media was negative after 16 weeks. We briefly discuss the pathogenesis, diagnosis and treatment. Finally, we comment on some aspects of the situation of tuberculosis among indigenous Colombian communities.

    To assure national leadership in space operations and exploration in the future, NASA must be able to provide cost effective and operationally efficient space transportation. Several NASA studies and the joint NASA/DoD Space Transportation Architecture Studies (STAS) have shown the need for a multi-vehicle space transportation system with designs driven by enhanced operations and low costs. NASA is currently studying an advanced manned launch system (AMLS) approach to transport crew and cargo to the Space Station Freedom. Several single and multiple stage systems from air-breathing to all-rocket concepts are being examined in a series of studies potential replacements for the Space Shuttle launch system in the 2000-2010 time frame. Rockwell International Corporation, under contract to the NASA Langley Research Center, has analyzed a two-stage all-rocket concept to determine whether this class of vehicles is appropriate for the AMLS function. The results of the pre-phase A study are discussed.

  5. Enhanced performance for the manned maneuvering unit

    Bingham, Paul E.

    We have all seen the Manned Maneuvering Unit (MMU) on television, in the newspaper, magazines and any number of other places. It is probably one of the most widely recognized articles ever put into orbit. This paper briefly describes the MMU. The description includes an overview of the controls and physical features and a discussion of the propulsion and electrical systems. Operational experience to date is briefly covered. The MMU was first used on STS 41-B for the first untethered space walk on February 7, 1984. Next usage was for the Solar Max mission on STS 41-C, followed by the retrieval of the Westar and Palapa communication satellites on mission STS 51-A in November, 1984. One of the "lessons learned" during these space operations was the need for enhanced performance by the MMU, and leads into a discussion of how that increased performance capability will be provided. Current work on a Propellant Tank Kit (PTK), which will provide enhanced performance, is shown. The PTK will provide sufficient propellant storage capability such that the MMU with PTK will have twice the previous delta velocity capability; i.e., double the MMU's maneuvering ability. Results of development testing in the NASA/JSC Weightless Environment Test Facility are included. Current status of PTK development is presented. This paper ends with a brief discussion of proposed space operations using the enhanced MMU performance in erecting space structures from the Space Shuttle, assembling and maintaining Space Station, rescue-transfer of astronauts and other space operations.

    The present review aimed to suggest approaches to prospective medical problems related to the health maintenance of space crews during future manned interplanetary, particularly Martian, missions up to 2-3 years with a possible stay on a planet with gravity different from that on Earth. The approaches are based on knowledge so far obtained from our analysis of the medical support of long-term orbital flights up to one year, as well as on the consideration of specific conditions of interplanetary missions. These specific conditions include not only long-term exposure to microgravity, but also a prolonged stay of unpredictable duration (2-3 years) on board a spacecraft or on a planet without direct contact with Earth, and living in a team with a risk of psychological incompatibility and the impossibility of an urgent return to Earth. These conditions necessitate a highly trained medical person in the crew, diagnostic tools and equipment, psychophysiological support, countermeasures, as well as the means for urgent, including surgical, treatment on board a spacecraft or on a planet. In this review, the discussion was focused on the following predictable medical problems during an interplanetary mission; 1) unfavorable effects of prolonged exposure to microgravity, 2) specific problems related to Martian missions, 3) medical monitoring, 4) countermeasures, 5) psychophysiological support and 6) the medical care system.

    Available in abstract form only. Full text of publication follows: One of the main tasks of the radiation safety guarantee is non-admission of the excess over critical radiation levels. In Russia they are man-caused radiation levels. Meanwhile any radiation measurement represents total radioactivity. That is why it is hard to assess natural and man-caused contributions to total radioactivity. It is shown that soil radioactivity depends on natural factors including radioactivity of rocks and cosmic radiation as well as man-caused factors including nuclear and non-nuclear technologies. Whole totality of these factors includes unpredictable (non-deterministic) factors - nuclear explosions and radiation accidents, and predictable ones (deterministic) - all the rest. Deterministic factors represent background radioactivity whose trends is the base of the radiation forecast. Non-deterministic factors represent man-caused radiation treatment contribution which is to be controlled. This contribution is equal to the difference in measured radioactivity and radiation background. The way of calculation of background radioactivity is proposed. Contemporary soils are complicated technologically influenced systems with multi-leveled spatial and temporary inhomogeneity of radionuclides distribution. Generally analysis area can be characterized by any set of factors of soil radioactivity including natural and man-caused factors. Natural factors are cosmic radiation and radioactivity of rocks. Man-caused factors are shown on Fig. 1. It is obvious that man-caused radioactivity is due to both artificial and natural emitters. Any result of radiation measurement represents total radioactivity i.e. the sum of activities resulting from natural and man-caused emitters. There is no gauge which could separately measure natural and man-caused radioactivity. That is why it is so hard to assess natural and man-caused contributions to soil radioactivity. It would have been possible if human

    Background Myocardial revascularization surgery is the best treatment for dyalitic patients with multivessel coronary disease. However, the procedure still has high morbidity and mortality. The use of extracorporeal circulation (ECC) can have a negative impact on the in-hospital outcomes of these patients. Objectives To evaluate the differences between the techniques with ECC and without ECC during the in-hospital course of dialytic patients who underwent surgical myocardial revascularization. Methods Unicentric study on 102 consecutive, unselected dialytic patients, who underwent myocardial revascularization surgery in a tertiary university hospital from 2007 to 2014. Results Sixty-three patients underwent surgery with ECC and 39 without ECC. A high prevalence of cardiovascular risk factors was found in both groups, without statistically significant difference between them. The group "without ECC" had greater number of revascularizations (2.4 vs. 1.7; p <0.0001) and increased need for blood components (77.7% vs. 25.6%; p <0.0001) and inotropic support (82.5% vs 35.8%; p <0.0001). In the postoperative course, the group "without ECC" required less vasoactive drugs, (61.5% vs. 82.5%; p = 0.0340) and shorter time of mechanical ventilation (13.0 hours vs. 36,3 hours, p = 0.0217), had higher extubation rates in the operating room (58.9% vs. 23.8%, p = 0.0006), lower infection rates (7.6% vs. 28.5%; p = 0.0120), and shorter ICU stay (5.2 days vs. 8.1 days; p = 0.0054) as compared with the group with ECC surgery. No difference in mortality was found between the groups. Conclusion Myocardial revascularization with ECC in patients on dialysis resulted in higher morbidity in the perioperative period in comparison with the procedure without ECC, with no difference in mortality though.

    The kinetics of the immunoglobulin (Ig) M type antibody to the hepatitis D virus (IgM anti-HD) were investigated in hepatitis B surface antigen (HBsAg) carriers with chronic hepatitis D treated with interferon (IFN) and in patients with terminal hepatitis delta virus (HDV) cirrhosis who underwent liver transplantation. The IgM antibody disappeared in each of 8 patients who responded to IFN therapy with the persistent normalization of aminotransferases and with the clearance of serum HBsAg and HDV-RNA. The IgM reactivity did not decline in the 45 treated patients who did not respond to the cytokine or who experienced a relapse after responding while on therapy. The antibody rapidly disappeared from serum post-transplantation in each of 10 examined patients with HDV who underwent transplantation. In 5 patients who underwent transplantation and who became reinfected with HDV, the antibody remained undetectable during the early reinfection phase, as marked by HDV replication and by the absence of liver damage; however, it rapidly raised to pre-transplantation levels with the recurrence of hepatitis D (HD) in the liver graft. Monomeric 7S IgM anti-HD predominated over pentameric 19S antibody in each of the two patients examined for IgM anti-HD molecular species. The IgM antibody to HDV raises in response to HDV-induced damage and represents a valid surrogate marker of liver damage which is immunopathologically related to HDV infection. Besides providing diagnostic information, it provides the best predictor of impending resolution of chronic HDV disease, whether spontaneous or IFN-induced.

    This prospective, single-center, observational study evaluated prognostic value of clinical SYNTAX score (CSS) on 2-year outcomes in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI). The SYNTAX score (SS) is a scoring system based on the complexity and severity of coronary lesions and is thought to be a prognostic tool to predict long-term outcomes. However, SS was a sole angiographic grading tool only with no consideration for clinical factors. There are few studies investigating the prognostic value of CSS in patients with ACS who underwent PCI. From January 2013 to December 2013, 6,099 consecutive patients with ACS admitted to FuWai hospital and underwent PCI were enrolled in this study. Based on CSS, patients were divided into low CSS group (CSS ≤ 6.5; 2,012 patients), mid-CSS group (6.5 < CSS < 13.8; 2,056 patients), and high CSS group (CSS ≥ 13.8; 2,031 patients). At 2-year follow-up, rates of cardiac death and major adverse cardiac events (MACE) were significantly higher in the high CSS group. Compared with baseline SS, CSS demonstrated significantly improved performance for 2-year cardiac death (receiver-operating characteristic curve C-statistic: 0.74 vs 0.62, p <0.001) but not for MACE (receiver-operating characteristic curve C-statistic: 0.60 vs 0.59, p = 0.29). By multivariable analysis, the CSS combined with PCI history and hypertension were strong predictors for cardiac death and CSS, intra-aortic balloon pump support, diabetes, and successful PCI were independent predictors for MACE. In conclusion, compared with the anatomic SS, CSS was suitable in risk stratifying and predicting 2-year clinical outcome among ACS population.

    Introduction To assess the clinical presentation of patients who underwent surgical exploration for acute scrotum and to investigate the potentially related factors for differential dignosis. Material and methods We retrospectively analyzed the medical records of 97 patients who underwent surgical exploration for acute scrotum between May 2007 and July 2013. The patients were divided into two groups as follows: Group1 included patients with testicular torsion (TT) and Group 2 contained patients with acute scrotal pathologies other than TT, including torsion of the testicular appendage, epididymo-orchitis, trauma and Henoch-Schönlein purpura. The physical examination findings, colour Doppler ultrasound (CDUS) and laboratory findings for the groups were compared. Results In total, 97 scrotal explorations were carried out for acute scrotum. Group 1 included 72 patients (74.2%) and Group 2 included 25 patients (25.8%). Group 2 was comprised of patients with torsion of the testicular appendage (n = 13), epididymo-orchitis (n = 8), testicular trauma (n = 2) and Henoch-Schönlein purpura (n = 2). In Group 1, 32 cases (44.4%) presented to a hospital less than 6 hours after onset of pain. More than half (64%) of Group 2's cases presented more than 24 hours after pain onset. Fever and pyuria appeared more frequently in Group 2 than in Group 1 and the results reached statistical significance (p = 0.001 and p = 0.044, respectively). Group 1 had more testicular tenderness than Group 2 (p <0.001). Our testicular salvage rate was 59.7%, and 40.3% of patients underwent orchiectomy. Conclusions CDUS predicted the diagnosis of TT (sensitivity 98.6%). Furthermore, clinical findings may also play a substantial role in the differential diagnosis of acute scrotum. PMID:26251755

    Pseudomyxoma peritonei is a rare, chronic relapsing disease in which tumor cells in the abdomen produce excessive mucin with a significant mortality rate. We describe a young unmarried nulligrava who underwent fertility preservation by in vitro fertilisation and embryo cryopreservation prior to radical surgery and adjuvant chemotherapy. Pregnancy was achieved, although complicated by obstructive uropathy. She delivered a healthy infant at 32 weeks' gestation. The few descriptions of fertility and pregnancy outcome in pseudomyxoma peritonei that appear in the literature are reviewed. PMID:22523631

    Acute renal failure associated with Plasmodium falciparum infection is already well recognized. Nevertheless, end-stage chronic renal failure and falciparum malaria comorbidity is a rare condition. We report a case of Plasmodium falciparum infection in a young male Javanese patient with end-stage chronic renal failure who underwent regular hemodialysis. This rare comorbidity led to rapid deterioration of consciousness and metabolic disturbances which had already existed in end-stage renal failure. Because of the immunosuppressive condition due to organ failure, the patient did not survive despite anti-malarial chemotherapy.

    We present the second case of paraparesis secondary to ossification of the ligamentum flavum at the midthoracic region in a black man. Ossification of the ligamentum flavum is frequently described in the Japanese population where the presentation is often in the lower thoracic region. The patient is a 37-year-old black man who, over the 6 months before admission, noticed progressive paraparesis. CT myelogram revealed severe thoracic stenosis by an ossified ligamentum flavum from T4 to T7 with most severe involvement at the T5, T6, and T7 levels. The patient underwent multilevel laminectomies and medial facetectomies from T4 to T7. Over the past decade, ossification of the ligamentum flavum has been reported with increasing frequency in non-Asian patients. This is the third case report in a black man. In addition, ossification of the ligamentum flavum in this particular location is rarely reported. The increased use of advanced neuroimaging techniques in the evaluation of "back pain" may reveal that the prevalence of this condition is higher than expected in non-Asian populations. Improvement in neurologic symptoms secondary to decompressive laminectomies will depend on the degree and duration of spinal cord compression.

  15. Pharmacokinetics of the penicillins in man.

    1976-01-01

    The purpose of this article is to review and summarise those aspects of the pharmacokinetic behaviour of the penicillins that may be of particular interest to the clinician. While these antibiotics differ markedly in their acid stability and oral absorption, misleading inferences may be drawn from simple inspection of the maximal serum concentrations produced by a given dose administered orally. A more accurate picture emerges when serum protein binding and intrinsic activity of the drugs are taken into account. All of the penicillins are readily and actively secreted by the renal tubles and most are eliminated, almost completely unchanged, in the urine. The majority are excreted in small quantities in the bile, but this is a major route for elimination of nafcillin from the body. Distribution of the penicillins in 'non-specialised' sites is excellent. In contrast, penetration of the central nevous system and eye are poor, and of the prostate, minimal. Inflammation reduces the barries to penetration of these areas. However, quantitative data related to this phenomenon in man are few. Probenecid actively competes with the 'export' pump of the meninges and renal tubular cells. This results in an increase in concentrations of the penicillins in the blood and cerebrospinal fluid. The effect of this agent on active secretion of these antibiotics from the eye and biliary tract is minimal. While elimination of the penicillins from the body takes place largely via renal excretion, penicillin V and oxacillin are extensively degraded as well. In contrast to the situation with respect to 'natural' and 'broad-spectrum' penicillins, the serum half-life of the isoxazolyl congeners and nafcillin is only minimally prolonged in the presence of renal failure. These agents are only weakly haemodialyzable, while the other penicillins are rapidly removed from the circulation by this procedure.

  16. Testosterone and aggressive behavior in man.

    Atavistic residues of aggressive behavior prevailing in animal life, determined by testosterone, remain attenuated in man and suppressed through familial and social inhibitions. However, it still manifests itself in various intensities and forms from; thoughts, anger, verbal aggressiveness, competition, dominance behavior, to physical violence. Testosterone plays a significant role in the arousal of these behavioral manifestations in the brain centers involved in aggression and on the development of the muscular system that enables their realization. There is evidence that testosterone levels are higher in individuals with aggressive behavior, such as prisoners who have committed violent crimes. Several field studies have also shown that testosterone levels increase during the aggressive phases of sports games. In more sensitive laboratory paradigms, it has been observed that participant's testosterone rises in the winners of; competitions, dominance trials or in confrontations with factitious opponents. Aggressive behavior arises in the brain through interplay between subcortical structures in the amygdala and the hypothalamus in which emotions are born and the prefrontal cognitive centers where emotions are perceived and controlled. The action of testosterone on the brain begins in the embryonic stage. Earlier in development at the DNA level, the number of CAG repeats in the androgen receptor gene seems to play a role in the expression of aggressive behavior. Neuroimaging techniques in adult males have shown that testosterone activates the amygdala enhancing its emotional activity and its resistance to prefrontal restraining control. This effect is opposed by the action of cortisol which facilitates prefrontal area cognitive control on impulsive tendencies aroused in the subcortical structures. The degree of impulsivity is regulated by serotonin inhibiting receptors, and with the intervention of this neurotransmitter the major agents of the neuroendocrine

    Owing to the increasing population of elderly patients, a large number of patients with degenerative spondylosis are currently being surgically treated. Although basic measures for decreasing postoperative surgical infections (PSIs) are considered, it still remains among the leading causes of morbidity and mortality. The aim of this retrospective analysis is to present possible causes leading to PSI in patients who underwent surgery for lumbar degenerative spondylosis and highlight how it can be avoided to decrease morbidity and mortality. The study included 540 patients who underwent posterior stabilization due to degenerative lumbar stenosis between January 2013 and January 2014. The data before and after surgery was retrieved from the hospital charts. Patients with degenerative lumbar stenosis who were operated upon in this study had >2 levels of laminectomy and facetectomy. For this reason, posterior stabilization was performed for all the patients included in this study. Determining the causes of postoperative infection (PI) following spinal surgeries performed with instrumentation is a struggle. Seventeen different parameters that may be related to PI were evaluated in this study. The presence of systemic diseases, unknown glove perforations, and perioperative blood transfusions were among the parameters that increased the prevalence of PI. Alternatively, prolene sutures, double-layered gloves, and the use of rifampicin Sv (RIS) decreased the incidence of PI. Although the presence of systemic diseases, unnoticed glove perforations, and perioperative blood transfusions increased PIs, prolene suture material, double-layered gloves, and the use of RIS decreased PIs.

    Pretest probability of coronary artery disease (CAD) facilitates diagnosis and risk stratification of CAD. Stress myocardial perfusion imaging (MPI) and chronic kidney disease (CKD) are established major predictors of cardiovascular events. However, the role of CKD to assess pretest probability of CAD has been unclear. This study evaluates the role of CKD to assess the predictive value of cardiovascular events under consideration of pretest probability in patients who underwent stress MPI. Patients with no history of CAD underwent stress MPI (n = 310; male = 166; age = 70; CKD = 111; low/intermediate/high pretest probability = 17/194/99) and were followed for 24 months. Cardiovascular events included cardiac death and nonfatal acute coronary syndrome. Cardiovascular events occurred in 15 of the 310 patients (4.8 %), but not in those with low pretest probability which included 2 CKD patients. In patients with intermediate to high pretest probability (n = 293), multivariate Cox regression analysis identified only CKD [hazard ratio (HR) = 4.88; P = 0.022) and summed stress score of stress MPI (HR = 1.50; P < 0.001) as independent and significant predictors of cardiovascular events. Cardiovascular events were not observed in patients with low pretest probability. In patients with intermediate to high pretest probability, CKD and stress MPI are independent predictors of cardiovascular events considering the pretest probability of CAD in patients with no history of CAD. In assessing pretest probability of CAD, CKD might be an important factor for assessing future cardiovascular prognosis.

    Comorbidities had considerable effects on the development of postoperative ileus (POI). The primary aim of the present study was to determine the influence of the age-adjusted Charlson comorbidity index (ACCI) score on the risk of prolonged POI in patients with colorectal cancer who underwent surgical resection. Using the electronic Hospitalization Summary Reports, we identified 11,397 patients with colorectal cancer who underwent surgical resection from 2013 through 2015. Logistic regression models were applied to evaluate the effect of the ACCI score on the risk of prolonged POI. The ACCI score had a positive graded association with the risk of prolonged POI in both colon and rectal cancer (P for trend < 0.05). Among patients with rectal cancer, after adjusting for potential confounders, those with an ACCI score of 4-5 had a 108% higher risk of prolonged POI than those with an ACCI score of 0-1 (odds ratio [OR], 2.08; 95% confidence interval [CI], 1.09-3.98), and those with an ACCI score of ≥ 6 had a 130% higher risk (OR, 2.30; 95% CI, 1.08-4.89). Among patients with colon cancer, those with an ACCI score of ≥ 6 had a 47% greater risk of prolonged POI than those with an ACCI score of 0-1 (OR, 1.47; 95% CI, 1.07-2.02). These findings suggested that a higher ACCI score was an independent predictor of the development of prolonged POI.

    A method to achieve man-in-the-control-loop simulation is presented. Emerging real-time dynamics simulation suggests a potential for creating an interactive design workstation with a human operator in the control loop. The recursive formulation for multibody dynamics simulation is studied to determine requirements for man-in-the-control-loop simulation. High speed computer graphics techniques provides realistic visual cues for the simulator. Backhoe and robot arm simulations are implemented to demonstrate the capability of man-in-the-control-loop simulation.

    Joseph Carey Merrick was born like all other children in his time, yet his life story was unlike those of other people due to an odd disfiguring disease that devastated his appearance. Despite his personal and social handicap caused by his deformity, Joseph Merrick did his best to survive the challenges of every-day living in a hostile and unsympathetic world. This is the story of a man who had to cover his face from the crows behind a mask, a man whose bones have yet to find eternal peace. This is the story of the "elephant man".

    Lenorovitz, Jeffrey M.

    1993-01-01

    A proprietary feasibility evaluation is presented for more cost-effective means of accomplishing manned lunar missions than those of the Apollo program. The proposal involves a series of flights employing the Space Shuttle Orbiter and an expendable launcher such as the Ariane 5, which would be supplied by the ESA. The crew module would be externally similar to the Apollo three-man capsule, but would be smaller due to a two-man crew. Cost projections are made which encompass hardware development, production, testing, and operations (including those of the Space Shuttle and Ariane 5).

    BurnMan determines seismic velocities for the lower mantle. Written in Python, BurnMan calculates the isotropic thermoelastic moduli by solving the equations-of-state for a mixture of minerals defined by the user. The user may select from a list of minerals applicable to the lower mantle included or can define one. BurnMan provides choices in methodology, both for the EoS and for the multiphase averaging scheme and the results can be visually or quantitatively compared to observed seismic models.

    A 68-year-old man underwent total gastrectomy for Type 3 gastric cancer with liver metastasis. The final finding was T3(SE), N1, H1, P0, CY0(class IV), Stage IV, Cur C. After surgery, he was treated with combination chemotherapy of weekly paclitaxel(PTX)/doxifluridine(5'-DFUR). Paclitaxel was administered at a dose of 80 mg/m(2) on day 1, 8 and 15, and doxifluridine was orally administered at a dose of 533 mg/m(2) day for five days followed by withdrawal for two days. This regimen was repeated every four weeks. After 2 courses, the tumor marker level normalized, and the size of the liver metastasis was remarkably decreased. After 5 courses, a CT scan revealed the liver metastasis had disappeared, and he has now survived without recurrence after the disappearance of the liver metastasis. No severe adverse reactions were observed, and the man can be treated as an outpatient. This therapy may thus be effective in the treatment of advanced gastric cancer following non-curative operation.

  7. Local Rhomboid Flap Reconstruction for Skin Defects After Excising Large Parotid Gland Tumors.

    2017-01-01

    Most parotid tumors grow slowly, and sometimes these patients do not request surgical treatment until the tumors become large and affect their appearance. The surgical treatment of these large tumors is usually accompanied by large skin defects after excision, and it is challenging for surgeons to close the defect primarily. This report describes the case of a 68-year-old man with a left parotid gland tumor (largest dimension, 110 mm) and the case of a 79-year-old man with a left parotid gland tumor measuring approximately 77 mm that had existed for decades. These patients underwent facial nerve dissection and parotidectomy with skin sacrifice. The large skin defects after the parotidectomy were successfully reconstructed with local rhomboid flaps. No facial palsy, wound disruption, flap edge loss, or major complications occurred after the surgeries. Except for the scars, the color of the cheek flap was not apparent from the periphery. In conclusion, local rhomboid flap reconstruction is a rapid and practical technique for reconstructing medium to large skin defects in the cheek and upper neck regions after tumor excisions. The flap was reliable in blood supply and cosmetic outcome.

  8. Physiologically constrained aerocapture for manned Mars missions

    NASA Technical Reports Server (NTRS)

    Lyne, James Evans

    1992-01-01

    Aerobraking has been proposed as a critical technology for manned missions to Mars. The variety of mission architectures currently under consideration presents aerobrake designers with an enormous range of potential entry scenarios. Two of the most important considerations in the design of an aerobrake are the required control authority (lift-to-drag ratio) and the aerothermal environment which the vehicle will encounter. Therefore, this study examined the entry corridor width and stagnation-point heating rate and load for the entire range of probable entry velocities, lift-to-drag ratios, and ballistic coefficients for capture at both Earth and Mars. To accomplish this, a peak deceleration limit for the aerocapture maneuvers had to be established. Previous studies had used a variety of load limits without adequate proof of their validity. Existing physiological and space flight data were examined, and it was concluded that a deceleration limit of 5 G was appropriate. When this load limit was applied, numerical studies showed that an aerobrake with an L/D of 0.3 could provide an entry corridor width of at least 1 degree for all Mars aerocaptures considered with entry velocities up to 9 km/s. If 10 km/s entries are required, an L/D of 0.4 to 0.5 would be necessary to maintain a corridor width of at least 1 degree. For Earth return aerocapture, a vehicle with an L/D of 0.4 to 0.5 was found to provide a corridor width of 0.7 degree or more for all entry velocities up to 14.5 km/s. Aerodynamic convective heating calculations were performed assuming a fully catalytic, 'cold' wall; radiative heating was calculated assuming that the shock layer was in thermochemical equilibrium. Heating rates were low enough for selected entries at Mars that a radiatively cooled thermal protection system might be feasible, although an ablative material would be required for most scenarios. Earth return heating rates were generally more severe than those encountered by the Apollo vehicles

    It is well known, that the president of the first Moldavian Parliament in 1918 was Ion Inculetz (borne on 5 april, 1884, Rezeni vill., Lapusna county, Basarabia - died on 19 november 1940, Bucharest, regraved in Barnova, near Iasi). On 24 January 1918 this Parliament claimed the independence of Basarabia from the Russia (The Democratic Republic of Moldova). On 27 march of the same year in a solennele session the Parliament claimed "The Democratic Republic of Moldova (Basarabia) in its borders between Prut, Dniester rivers, Black Sea, and old borders with Austria, rupted by Russia more than one hundred years from the body of old Moldova, due to the historical right and due to the right of the selfdetermination of peoples, is unifying forever with She's mother Romania ". After the Unification Ion Inculetz activated as representative of Basarabia in the Romanian Parliament. He was a man of democratic views, a partisan of social-democracy in Russia, as well as in Romania after the unification. The progress of peoples was one of His main political goals. It is less known, however, that Inculetz was a remarkable physicist. This is the subject of the conference. After the finish of the secondary studies in Chisinau, He entered to Jur'ev (actually Tartu- Estonia) University Medecine Department, but after one year of studies He moved to Sankt-Petersburg Imperial University, where He specialized in physics and mathematics. After the finish of the Physical Mathematical Department he became private-docent (Associate Professor). Concomittantly He taught methematics at one of the comercial schhols in Sankt Petersburg. In the same time he was a Scientific Secretary of the journal "Nauchnoie Obozrenie" ("Scientific Review") and a researcher at the Meteorological Observatory in Sankt-Petersburg (since 1914). Since 1912 till 1917 He published a series of papers in the fields of physics and meteorology, particularly concerned to anodic rays, Krooks tubes, radiactivity, Doppler effect
