Protease stimulation in cultured normal human epidermal keratinocytes (NHEK) due to sulfur mustard (SM) exposure is well documented. However, the specific protease(s) stimulated by SM and the protease substrates remain to be determined. In this study, we observed that SM stimulates several proteases and the epidermal-dermal attachment protein laminin-5 is one of the substrates. We propose that ...
Despite advances in control via snail eradication and large-scale chemotherapy using praziquental, schistosomiasis continues to spread to new geographic areas particularly in sub-Saharan Africa. Presently, there is no vaccine for controlling this disease. We have concentrated on a functionally important schistosome antigen Sm-p80 as a possible vaccine candidate for schistosomiasis. Here we repo...
The administration of certain monoclonal anti-Sm antibodies (2G7, 7.13) induced most MRL/lpr mice to become anti-Sm positive by 5 mo of age, although other anti-Sm monoclonals (Y2, Y12) suppressed the spontaneous response. Positive anti-Sm antibody enhancement occurred efficiently only in MRL/lpr mice and not in other systemic lupus erythematosus mice that have little spontaneous anti-Sm produc...
Hypertrophy was produced in the anterior latissimus dorsi (ALD) muscle of 5-wk-old chickens by application of a load to the humerus. After 4 wk, hypertrophied ALD muscles were greater than 2.5 times heavier than contralateral control ALD muscles. Two isomyosins are distinguishable in normal ALD muscles by their different electrophoretic mobilities. It is shown here that the faster migrating SM-...
این مقاله، حاصل پژوهشی گروهی است که هدف آن بررسی اهمیت و کاربرد شتاب دهنده ها در زندگی امروزی بوده است. در این مقاله علاوه بر بررسی کاربردهای گسترده شتاب دهنده ها در امور زندگی امروزی، رشد صعودی استفاده از آن ها در بخش های مختلف نیز به طور کمی گزارش شده است. ارائه آمار شتاب دهنده ها در کشورهای مختلف در کنار مقایسه وضعیت ایران در این زمینه، لزوم توجه بیشتر به این حوزه را نشان می دهد
The aim of this study was to compare a split marketing (SM) strategy, in which the heaviest pigs in a group are removed and slaughtered earlier than the others, with an all-out (AO) marketing strategy, in which all pigs are removed from the pen simultaneously and slaughtered on the same day, in terms of welfare, performance, and carcass traits of noncastrated (i.e., intact) male and female pigs...
Sulfur mustard (SM, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes DNA alkylation, protein modification and membrane damage. SM can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. Epigenetic regulation of gene expression is a growing research topic and is ...
SM-295291 and SM-369926 are new parenteral 2-aryl carbapenems with strong activity against major causative pathogens of community-acquired infections such as methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae (including penicillin-resistant strains), Streptococcus pyogenes, Enterococcus faecalis, Klebsiella pneumoniae, Moraxella catarrhalis, Haemophilus influenzae (includin...
Transcriptional activity of the smooth muscle (SM) α-actin gene is differentially regulated in SM vs. non-SM cells. Contained within the rat SM α-actin promoter are two MCAT motifs, binding sites for transcription enhancer factor 1 (TEF-1) transcriptional factors implicated in the regulation of many muscle-specific genes. Transfections of SM α-actin promoter-CAT constructs containing wild-type ...
Introduction. Most lunar meteorites have unique cosmic-ray exposure (CRE) histories with long exposure times on the Moon, followed by very short transfer times from the Moon to Earth, typically 10-10 yr. Due to these short transfer times of lunar meteorites in space, the inventories of most cosmogenic radionuclides with half-lives of 10-10 yr contain contributions from exposure in the lunar reg...
