Sphingomyelin (SM) biosynthesis is believed to occur in the early Golgi apparatus, plasma membrane and recycling endosomes. In the present study, the localization of the SM synthesis that follows its hydrolysis upon activation of the SM signal-transduction pathway was investigated in human skin fibroblasts treated with tumour necrosis factor (TNF) alpha. After TNFalpha-induced degradation, the ...
B y now you should be familiar with position isomers wherein compounds of the same molecular formula differ because substituents, chain branches, and so on, are not at the same positions in the molecules. 1-Chloropropane and 2-chloropropane are straightforward examples of position isomers. A much more subtle form of isomerism is present when two dijfjrerent compounds have the same molecular for...
امروزه کاربرد دادههای سنجش از دور در منابع آب، بهویژه در مدیریت آبیاری بهطور گسترده‍ای مورد توجه محققان قرار گرفته است. در این تحقیق، امکان یابی کاربرد مدل توازن انرژی بهمنظور تخمین تبخیر- تعرق و ارزیابی بهرهوری آب کشاورزی با استفاده از دادههای ماهوارهای در منطقه وسیعی از شبکه آبیاری دشت قزوین مورد بررسی قرار گرفت. لذا، از الگوریتم بیلان انرژی سطح (sebal) برای محاسبه تبخیر- تعرق استفا...
Arteriolar growth is an important event in the adaptation of normal tissues as well as in important pathologies, but the site of origin of new arterioles remains unknown. The network pattern of arteriolar development in skeletal muscle was detected by use of a new immunohistochemical technique that is based on the observation that fully differentiated (mature) vascular smooth muscle (SM) cells ...
To explore mechanisms contributing to the clinical heterogeneity of systemic mastocytosis (SM) and to suboptimal responses to diverse therapies, we analyzed 39 KIT D816V mutated patients with indolent SM (n = 10), smoldering SM (n = 2), SM with associated clonal hematologic nonmast cell lineage disorder (SM-AHNMD, n = 5), and aggressive SM (n = 15) or mast cell leukemia (n = 7) with (n = 18) or...
Three types of Staphylococcus aureus strains were isolated with respect to streptomycin (SM) and spectinomycin (SPC) resistance, namely, SM(r)SPC(r), SM(r)SPC(s), and SM(s)SPC(r) (r, resistant; s, sensitive). Curing experiments and transduction analysis of strain MS7990 (SM(r).SPC(r).EM(r)) (EM, erythromycin) disclosed that the loci governing SM and SPC resistance are different and exist on dif...
Abstract. In this paper, we propose a family of surrogate maximization (SM) algorithms for multi-class logistic regression models (also called conditional exponential models). An SM algorithm aims at turning an otherwise intractable maximization problem into a tractable one by iterating two steps. The S-step computes a tractable surrogate function to substitute the original objective function, ...
Background: Using human skin-fibroblast cell line HF2FF, the efficacy of some drugs was evaluated against sulfur mustard (SM) cytotoxicity. The drugs were the sulfhydryl containing molecule including N-acetylcysteine (NAC), 2-oxo-thiazolidine-4-carboxylate (OTC) and acetaminophen as glutathione (GSH) stimulator pathway. Methods: The protective effects of NAC (0.1 mM), OTC (1.8 mM), and acetami...
Background and objective:Many biochemical features of sulfur mustard (SM) intoxication remained unknown. So far, the direct association between biochemical parameter changes and ocular problems in patients exposed to SM is not evaluated.The current study aimed at evaluating the associations between the ocular findings in patients with SM intoxication and the changes of...
PURPOSE To compare cryopreserved human corneal endothelial cells (HCECs) grown in human serum-supplemented media (HS-SM) with cryopreserved HCECs grown in fetal bovine serum-supplemented media (FBS-SM). METHODS Three pairs of human corneas from donors aged 8, 28, and 31 years were obtained from the eye bank. From each pair, one cornea was used to start a HCEC culture using HS-SM; the other co...
