BACKGROUND Mild traumatic brain injury (MTBI) can sometimes lead to persistent postconcussion symptoms. One well accepted hypothesis claims that chronic PCS has a neural origin, and is related to neurobehavioral deficits. But the evidence is not conclusive. In the attempt to characterise chronic MTBI consequences, the present experiment used a group comparison design, which contrasted persons (...

AIMS To determine etiopathogenetic factors, predictors of in-hospital morbidity and mortality, and discharge status in a serially recruited cohort of PCS patients at a tertiary care hospital. Comparison of data between ACS and PCS groups was also done. METHODS Seventy six cases of PCS and 108 cases of ACS were serially recruited, within 48 hrs of stroke onset, over a 2 year period. Vascular t...

OBJECTIVE Altered anterior cingulate cortex activity has been consistently detected by functional imaging in schizophrenia patients. In the present study, we hypothesized that the detection of such local hypoactivity varies when the subjects' local gyrification is monitored. Using a group-statistical approach, we investigated whether the presence or absence of a paracingulate sulcus (PCS) does ...

Pneumocystis carinii f. sp. suis (PCS) nucleic acid and antibody profiles on two Austrian-farrow-to-finish farms were investigated. Furthermore, associations with other respiratory pathogens were evaluated. Respiratory specimen and sera from pigs of five age classes between the 1st week and the 3rd month of life as well as samples from sows were analyzed. On Farm A, PCS infection occurred early...

We investigated the morphological alterations in the Purkinje cells (PCs) of the cerebellar cortex of young adult (2–3 years old) and old cats (12–13 years old). Rapid Golgi staining was used to visualize dendritic arborizations and spines, and routine Nissl staining was applied to visualize the somatic configuration of the PCs. The height, width and area of the dendritic network were measured,...

Background. Postconcussion symptoms (PCSs)-such as fatigue, headache, irritability, dizziness, and impaired memory-are commonly reported in patients who have mild traumatic brain injuries (MTBIs). Evaluation of PCS after MTBI is proposed to have a diagnostic value although it is unclear whether PCS are specific to MTBI. After whiplash injuries, patients most often complain of headaches and neck...

Bacterial cellulose has been used in the food industry for applications such as low-calorie desserts, salads, and fabricated foods. It has also been used in the paper manufacturing industry to enhance paper strength, the electronics industry in acoustic diaphragms for audio speakers, the pharmaceutical industry as filtration membranes, and in the medical field as wound dressing and artificial s...

BACKGROUND & AIMS To determine the pathogenesis of liver nodules, and lesions similar to obliterative portal venopathy, observed after portosystemic shunts or portal vein thrombosis in humans. METHODS We conducted an experimental study comparing portacaval shunt (PCS), total portal vein ligation (PVL), and sham (S) operated rats. Each group were either sacrificed at 6 weeks (early) or 6 month...

Plants, like other organisms, have adaptive mechanisms whereby they are able to respond to both nutrient deficiencies and toxicities. Phytochelatins (PCs) play an essential role in heavy-metal detoxification in plants, fungi and worms. PCs chelate heavy metals and then PCmetal complexes are translocated across the tonoplast and sequestered in vacuoles. PCs are synthesized from glutathione by th...
