For a long time, it was accepted that calcium and cephalin activate prothrombin. There were secondary questions about the identity of the phosphatide and whether it was important that the phosphatide be bound to protein. Otherwise the issue was closed. Now the basic premise is in sufficient doubt to warrant a restatement of the problem in the light of newer observations. " . . . I have come upo...

The physicochemical stability of an aqueous, phospholipid-based dispersion of itraconazole microcrystals was studied as a model water-insoluble drug suspension. The particle size, phospholipid concentrations, free fatty acid (FFA) content, pH, and zeta potential of two test suspensions were followed over 63 days at 5 and 40 degrees C storage conditions. Hydrolysis of a control suspension contai...

MOTIVATION RNA sequencing enables allele-specific expression (ASE) studies that complement standard genotype expression studies for common variants and, importantly, also allow measuring the regulatory impact of rare variants. The Genotype-Tissue Expression (GTEx) project is collecting RNA-seq data on multiple tissues of a same set of individuals and novel methods are required for the analysis ...

osting by E C BY-NCAbstract Lipoid proteinosis is an autosomal recessive disease of abnormal deposition of glycoprotein in various tissues. Symptoms may include a hoarse voice, lesions and scarring on the skin, easily damaged skin with poor wound healing, dry, wrinkly skin, and beading of the papules around the eyelids. Calcifications of brain tissue can lead to epilepsy and neuropsychiatric ab...

BACKGROUND Rodent approach-avoidance conflict tests are common preclinical models of human anxiety disorder. Their translational validity mainly rests on the observation that anxiolytic drugs reduce rodent anxiety-like behavior. Here, we capitalized on a recently developed approach-avoidance conflict computer game to investigate the impact of benzodiazepines and of amygdala lesions on putative ...

Lipoid proteinosis is a rare autosomal recessive inherited metabolic disorder characterized by deposition of a hyaline-like material in the skin, oral laryngeal mucosa, and in other sites. In this report, the author describes 2 Saudi siblings who had characteristic skin findings, oral and mucosal lesions, histological findings along with few rarely encountered manifestations including pathognom...

Silicosis remains a common occupational respiratory disease. Even in this era of highly sophisticated hygiene in European countries, new occupational cases of silicosis continue to be reported. Four cases of silicosis which developed after a relatively short occupational exposure to respirable silica among the members of one family are described. Four young men worked illegally abroad in mining...

Oxytocin (OT) is becoming increasingly established as a prosocial neuropeptide in humans with therapeutic potential in treatment of social, cognitive, and mood disorders. However, the potential of OT as a general facilitator of human learning and empathy is unclear. The current double-blind experiments on healthy adult male volunteers investigated first whether treatment with intranasal OT enha...

The amygdala is believed to play a major role in orienting attention towards threat-related stimuli. However, behavioral studies on amygdala-damaged patients have given inconsistent results-variously reporting decreased, persisted, and increased attention towards threat. Here we aimed to characterize the impact of developmental amygdala damage on emotion perception and the nature and time-cours...

Lipoid proteinosis, a rare autosomal recessive disorder, presents in early childhood with hoarseness, skin infiltration and thickening, beaded papules on eyelid margins, and facial acneiform or pock- like scars. Although
