It has been suggested that in systemic sclerosis (SSc) the primary fault is in the microcirculation.' If this were so, then topical glyceryl trinitrate (GTN) might favourably influence skin blood flow and elasticity in areas of sclerodermatous skin change. Ten patients (three men, seven women; median age 48 years, range 24-70) fulfilling the American Rheumatism Association criteria for SSc2 wer...

PURPOSE To evaluate the effects of aroeira (Schinus terebinthifolius) ointment on skin wound healing in rats. METHODS Adult male rats (n=20) were divided into four groups of five animals each, as follows: G4, G7, G14 and G21, which corresponds to 4th, 7th, 14th and 21th days postoperatively. Each animal were made two incisions on the skin, including the subcutaneous tissue, in the right and l...

Abstract It is estimated that one-fifth of the general population may have allergic contact dermatitis (ACD) to common environmental allergens. Skincare companies are increasingly advertising their products as ‘hypoallergenic’, targeting consumers who seek personal care (PCPs) less likely cause an reaction. However, there no Food and Drug Administration standards regulate use term hypoallergeni...

Infrared spectroscopy has been calibrated to provide a precise and accurate method for determining the concentrations of molecular water and hydroxyl groups in hydrous albitic glasses. At total water contents less than 4 wt. %, most of the water is dissolved as hydroxyl groups; at higher total water contents, molecular water becomes the dominant species. For total water cont~nts above 4 wt. %, ...

Current knowledge on the solidus temperature for carbonated eclogites suggests that carbonatitic liquids should not form from a subducted oceanic lithosphere at sub-arc depth. However, the oceanic crust includes a range of gabbroic rocks, altered on rifts and transforms, with large amounts of anorthite-rich plagioclase forming epidote on metamorphism. Epidote disappearance with pressure depends...

Exoelectrogenic bacteria have potential for many different biotechnology applications due to their ability to transfer electrons outside the cell to insoluble electron acceptors, such as metal oxides or the anodes of microbial fuel cells (MFCs). Very few exoelectrogens have been directly isolated from MFCs, and all of these organisms have been obtained by techniques that potentially restrict th...

Blossomiis frolmi several varieties of orchids fade prematurely when their pollinia are removed or disturbed (2,3, 7), and also if the 'flowers are gassed with ethylene (8, 9, 10), pollinated (3, /7), or treated with an auxin (3, 7). Durinig natural ifading as wel' as that indu'ced by removal, of the 'pollinia, ethylene is evolved (2, 3, 9, 10), and therefore it has been inferred that the gas i...

Various efforts have been made in past in order to predict the underlying mechanism of pesticide-induced toxicity using in vitro and animal models, however, these predictions may or may not be directly correlated with humans. The present study was designed to investigate the carbofuran induced genotoxicity and its amelioration by vitamins C and E by treating human peripheral blood lymphocytes (...

Experimental work involving artificial maturation of modern sediments was carried out to determine if diamondoids can be generated from biosynthetic precursors abundant in modern sediments. Mineral catalysts of distinctive properties, including montmorillonite K10, acidic aluminosilicate and CaCO3 were used in the hydrous pyrolysis of organic-rich modern sediments to examine which type of catal...
