BACKGROUND Karoshi, or death due to overwork, has now become a serious social problem in China. Worsening of cardiovascular risks by stress might initiate karoshi. Many studies have examined the relationship between job stress and obesity, hypertension, and type 2 diabetes mellitus, but less evidence exists for dyslipidemia like hypo-high-density lipoproteinemia (hypo-HDL). The aim of this stud...

A continuing, sporadic incidence of vitamin E-selenium (Se) responsive disease among confinement-reared pigs believed to be fed complete and adequately supplemented diets prompted these studies on the potential genetic influence over vitamin E and Se metabolism in pigs. The initial study revealed a wide range of serum Se and vitamin E concentrations among age-matched, commonly housed and common...

We previously determined that both antecedent hypoglycemia and elevated cortisol levels blunt neuroendocrine and metabolic responses to subsequent hypoglycemia in conscious, unrestrained rats. The adrenal steroid dehydroepiandrosterone sulfate (DHEA-S) has been shown in several studies to oppose corticosteroid action. The purpose of this study was to determine if DHEA-S could preserve counterre...

AIMS We investigated whether rapid cooling instituted by total liquid ventilation (TLV) improves cardiac and mitochondrial function in rabbits submitted to ischaemia-reperfusion. METHODS AND RESULTS Rabbits were chronically instrumented with a coronary artery occluder and myocardial ultrasonic crystals for assessment of segment length-shortening. Two weeks later they were re-anaesthetized and...

Intracranial epidermoid cysts are generally located in the cerebellopontine and parasellar areas and appear hypo-dense on computed tomography and hypo-intense on T1-weighted magnetic resonance imaging. We report a case of an unusual epidermoid cyst of the cerebellopontine angle extending into the upper cervical canal that appeared hyper-dense on computed tomography scanning, hyper-intense on T1...

The resting potential of identified cells (Parker cells) in the abdominal ganglion of Elysia chlorotica (Gould) depolarizes by about 30 mV in response to a 50% reduction in osmolality and returns to the original potential in 20 min. Cell volume recovery requires approximately 2 h. Thus, recovery of the resting potential is not dependent on recovery of cell volume. The hypo-osmotic depolarizatio...

objective(s): genetic analysis of two consanguineous pakistani families with localized autosomal recessive hypotrichosis was performed with the goal to establish genotype-phenotype correlation. materials and methods: genomic dna extraction had been done from peripheral blood samples. extracted dna was then subjected to pcr (polymerase chain reaction) for amplification. linkage analysis was perf...

CONTEXT The initial diagnosis of pheochromocytoma relies on plasma fractionated metanephrines levels. Normal levels exclude pheochromocytoma, but positive tests have a low positive predictive value due to the disease's rarity. OBJECTIVES The objective of the study was to evaluate three approaches to distinguish between true-positive and false-positive tests: 1) increased cutoff for plasma fra...

rhinophyma is a severe late complication of rosacea, which is characterized by progressive hyperplasia of sebaceous glands and connective tissue involving the lower two-thirds of the nose. it can be an emotionally devastating disorder, and serve as a medium for occult cancers and other health problems. many surgical treatments have been advocated, as well as dermabrasion and laser therapy. in l...

The Reward Hypersensitivity Model of bipolar disorder argues that hypersensitivity to reward-relevant cues characterizes risk for hypo/mania. This hypersensitivity leads to increased goal-directed motivation during reward-relevant life events that, in the extreme, is reflected in hypo/manic symptoms. In line with this perspective, individuals with bipolar disorder display elevated activation in...
