Heightened activity of circulating Tissue Factor (TF) has been linked to a variety of macro- and microvascular cardiovascular complications commonly observed in diabetes mellitus. Systemic and localized vascular abnormalities comprise the most debilitating feature of diabetic pathophysiology. Blood monocytes are chronically activated in diabetes, and serve as the major source ...

By using a new type of a LaB6 hollow cathode tube, the abnormal properties of the electron energy distribution function are observed in the glow-arc transition. Besides the normal peak at low energy (~0.8 eV), another peak (~1-4 eV) appears and decays in this transition.

In patients with coronary arterial disease, stress imaging is able to demonstrate abnormalities in the motion of the ventricular walls, and abnormalities in coronary arterial perfusion not apparent at rest. It can also provide information on prognostic factors. In patients with congenitally malformed hearts, stress imaging is used to determine contractile ...

Lower urinary tract function consists of a complex interplay of neural input consisting of both involuntary and voluntary controls interacting with specialized anatomical structures. Damage to anatomical support structures may lead to derangements in urethral and bladder function. In addition, disorders related to physiological and ...

The role of this paper is to present the current concepts in anatomy and etiopathogenesis of pharyngeal diverticula. Precise anatomical considerations highly emphasizing the weak anatomic areas which predispose the pouch formation are discussed. Focus exposed in details will also be given upon the structural and functional characteristics of the upper esophageal sphincter as ...

Motion processing represents a perceptual domain in which dynamic visual information is encoded to support the perception of movement. Research over the last decade has found a variety of abnormalities in the processing of motion information in schizophrenia. The abnormalities span from discrimination of basic motion features (such as speed) to integration ...

Choristomas are tumor like masses consisting of tissues that are histologically normals but in abnormal location. These are rare in oral cavity and occur generally in tongue. There are seven categories of choristomas on the basis of types of tissues recognized. The presenting case in a gastric mucosal choristoma type, and the treatment was surgical excision. No recurrence of ...

Lipase (triacylglycerol acylhydrolases, E.C. 3.1.1.3.) is one of the most important enzymes applied to the broad range of industrial application field. Especially, lipases with abnormal functionality such as thermo stability, alkaline, acidic, cold-activity gain special attention because of their a...

The investigation of children with suspected inherited platelet disorders is challenging. The causes of mucocutaneous bleeding are many, and specialized testing for platelet disorders can be difficult to access or interpret. An algorithm developed for the investigation of suspected platelet disorders provides a sequential approach to evaluating both platelet ...

Skeletal growth is a dynamic process. A knowledge of the structure and function of the normal growth plate is essential in order to understand the pathophysiology of abnormal skeletal growth in various diseases. In this well-illustrated article, the authors provide a radiographic classification of abnormal growth plates and discuss ...

An officeworking population was surveyed to investigate respiratory symptoms and function abnormalities in relation to smoking and oxidant air pollution exposure. No effect of oxidant exposure on chronic bronchitis symptoms or function abnormalities could...

The detection of losses of special nuclear materials has been the subject of much research in recent years. The standard industry practice using ID/LEID will detect large magnitude losses. Time series techniques such as the Kalman Filter or CUSUM methods will detect small magnitude losses if they occur regularly over a sustained period of time. To date no technique has been ...

Insertion: A type of chromosomal abnormality in which a DNA sequence is inserted into a gene, disrupting the normal structure and function of that gene.

Infantile reflexes are tested and observed by medical professionals to evaluate neurological function and development. Absent or abnormal reflexes ...

Two energy conservation measures are described for supermarkets. These are: (1) multi-level photocell light controls; and (2) four set-point type demand limiters for special control after blackouts. The function and application of these new conservation measures are described in detail. The photocell light controls (which may be integrated into the energy ...

This article describes some of the newer techniques that are being used in the clinical assessment of patients following mild to moderate TBI, addresses their use in the acute setting, and explores their potential role in long-term follow-up. Also addressed are the challenges faced before some of these newer techniques can be incorporated into routine clinical management. Large studies are needed ...

Patients with sickle cell disease exhibits numerous kidney structural and functional abnormalities, changes that are seen along the entire length of the nephron. Changes are most marked in patients with homozygous sickle cell anemia, but are also seen in those with compound heterozygous states and the sickle cell trait. The renal features of sickle cell ...

Introduction: Early observations from lesion studies suggested right hemisphere (RH) dysfunction in ADHD. However, a strictly right-lateralized deficit has not been well supported. An alternatively view suggests increased R greater than L asymmetry of brain function and abnormal interhemispheric interaction. If true, RH pathology in ADHD should reflect ...

Radionuclide techniques are currently used to fully evaluate many congenital and acquired abnormalities of the gastrointestinal tract of children. Frequently, the anatomic and functional data provided by the nuclear examination are definitive. In the study of many disease entities, tracer techniques have replaced more cumbersome or invasive procedures. ...

The pathophysiology of dystonia has been best studied in patients with focal hand dystonia. A loss of inhibitory function has been demonstrated at spinal, brainstem and cortical levels. Many cortical circuits seem to be involved. One consequence of the loss of inhibition is a failure of surround inhibition, and this appears to directly lead to overflow and unwanted muscle ...

Alcohol induces a variety of changes in the liver: fatty change, hepatitis, fibrosis, and cirrhosis. The histopathological appearances of these conditions are discussed, with special attention to differential diagnosis. Many forms of alcoholic liver disease are associated with Mallory body formation and fibrosis. Mallory bodies are formed, at least in part, from intermediate ...
