background: osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. osteoporosis can be diagnosed easily with the use of dual-energy x-ray absorptiometry (dxa) equipment. the aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine ls in pre- and post-menopausal women from isfaha...
The anticancer effect of (1S,2S,3E,7E,11E)-3,7,11,15-cembratetraen-17,2-olide (LS-1) from Lobophytum sp. has been already reported in HT-29 human colorectal cancer cells. In this study, we examined the effect of LS-1 on the apoptosis induction of SNU-C5/5-FU, fluorouracil-resistant human colon cancer cells. Furthermore, we investigated whether the apoptosis-induction effect of LS-1 could arise ...
نفوذگرهای چاه نفت، ابزارهای انفجاری هستند که در صنعت حفاری چاه های نفت و گاز و با هدف دستیابی به مخازن اطراف چاه و افزایش بازده آن مورد استفاده قرار می-گیرند. کارایی این نفوذگرها با عمق نفوذی که ایجاد می کنند مورد سنجش قرار می گیرد، به همین دلیل پارامتر عمق به عنوان پارامتر اصلی باید مورد بررسی قرارگیرد. در این مقاله، گزارش کاملی از شبیه سازی عددی و بهینه سازی عملکرد این ابزارها که در حقیقت، خر...
LEOPARD syndrome-associated SHP2 mutation confers leanness and protection from diet-induced obesity.
LEOPARD syndrome (multiple Lentigines, Electrocardiographic conduction abnormalities, Ocular hypertelorism, Pulmonary stenosis, Abnormal genitalia, Retardation of growth, sensorineural Deafness; LS), also called Noonan syndrome with multiple lentigines (NSML), is a rare autosomal dominant disorder associating various developmental defects, notably cardiopathies, dysmorphism, and short stature. ...
تعیین عامل توپوگرافی (ls) به دلیل پیچیدگی اثر آن بر پیش بینی تلفات خاک با مدل rusle بسیار دشوار است. هدف این تحقیق تعیین مناسبترین ابعاد سلولی نقشة dem برای محاسبة عامل ls به روش moore and wilson (1992) در منطقهای به مساحت 5326 هکتار در شمال غرب استان تهران بود. بدین منظور، با استفاده از dem با ابعاد سلولی 10 متر نقشههای dem با ابعاد سلولی 30 و 50 و 100 و 200 و 400 متر در محیط arcgis 9.3 ای...
Modification by SUMO-1 is proposed to play a role in protein targeting and/or stability. The SUMO-1-conjugating enzyme Ubc9 interacts with androgen receptor (AR), a ligand-activated transcription factor belonging to the steroid receptor superfamily. We show here that AR is covalently modified by SUMO-1 (sumoylated) in an androgen-enhanced fashion and identify the principal acceptor site in the ...
We newly prepared lipopolyplexes containing N-lauroylsarcosine (LS) as a hybrid vector for pulmonary gene delivery via the systemic route. Lipopolyplexes were composed of polyethylenimine (PEI), N-[1-(2,3-dioleyloxy)propyl]-N,N,N-trimethlylammonium chloride (DOTMA), LS, and plasmid DNA (pDNA). The particle size of lipopolyplex of PEI, DOTMA, and pDNA (lipopolyplex 2P-2D) was not largely changed...
OBJECTIVE Leucaena leucocephala (Leucaena) is a perennial tropical legume that can be directly grazed or harvested and offered to ruminants as hay, silage, or fresh. However, Leucaena contain phenolic compounds, which are considered anti-nutritional factors as these may reduce intake, digestibility and thus animal performance. Therefore, the objective of this experiment was to determine effects...
INTRODUCTION The true incidence of urethral involvement in patients with genital lichen sclerosus (LS) is unknown. We review the epidemiology and discuss the pathogenesis of LS and urethral stricture diseases. MATERIALS AND METHODS During the period 1991-2002, of 925 patients who underwent urethroplasty for anterior urethral stricture, 130 patients (14%) received the diagnosis of LS. In all p...
In this paper we introduced and analyzed the Log-Sigmoid (LS) multipliers method for constrained optimization. The LS method is to the recently developed smoothing technique as augmented Lagrangian to the penalty method or modified barrier to classical barrier methods. At the same time the LS method has some specific properties, which make it substantially different from other nonquadratic augm...
