در سالهای اخیر تلاش زیادی برای سنتز کمپلکس های سوپرامولکول و پلیمرهای کوئوردیناسیونی بر مبنای لیگاندهای آلی چند دندانه شده است. این مواد به دلیل داشتن خواص منحصر به فرد، کاربردهای زیادی در صنعت دارند. سنتز پلیمرهای کوئوردیناسیونی جدید از سرب(ii) در ابعاد بالک(توده) و نانو با استفاده از روش گرادیان دمایی و به روش شاخه جانبی صورت گرفته و با روش طیف سنجی ir و پایداری گرمایی آن ها توسط آنالیزهای وز...
Neurospora fungi harbor a group of meiotic drive elements known as Spore killers (Sk). Spore killer-2 (Sk-2) and Spore killer-3 (Sk-3) are two Sk elements that map to a region of suppressed recombination. Although this recombination block is limited to crosses between Sk and Sk-sensitive (Sk(S)) strains, its existence has hindered Sk characterization. Here we report the circumvention of this ob...
The efficacy of three different treatment protocols was compared: 1) simple chest tube drainage (Drain); 2) adjunctive intrapleural streptokinase (IP-SK); and 3) an aggressive empirical approach incorporating SK and early surgical drainage (SK+early OP) in patients with pleural empyema and high-risk parapneumonic effusions. This was a nonrandomized, prospective, controlled time series study of ...
Using 13.4 fb of data collected with the CLEO detector at the Cornell Electron Storage Ring, we have observed 300 events for the two-photon production of ground-state pseudo-scalar charmonium in the decay ηc → K 0 SK π. We have measured the ηc mass to be (2980.4 ± 2.3 (stat) ± 0.6 (sys)) MeV and its full width as (27.0 ± 5.8 (stat) ± 1.4 (sys)) MeV. We have determined the two-photon partial wid...

Molecular subtype (MS) is one of the most used classifications breast cancer (BC). Four MSs are widely accepted according to receptor expression estrogen, progesterone, and HER2. The impact adipose tissue on BC MS metabolic impairment still unclear. present work aims elucidate alterations in cell lines representing different subjected adipocyte associated factors. Preadipocytes isolated from hu...
The mechanisms by which sphingosine kinase-1 (SK-1)/sphingosine 1-phosphate (S1P) activation contributes to imatinib resistance in chronic myeloid leukemia (CML) are unknown. We show herein that increased SK-1/S1P enhances Bcr-Abl1 protein stability, through inhibition of its proteasomal degradation in imatinib-resistant K562/IMA-3 and LAMA-4/IMA human CML cells. In fact, Bcr-Abl1 stability was...
Obesity is a risk factor for postmenopausal breast cancer and is associated with poor prognosis. Leptin, a cytokine synthesized in adipose tissue, has been implicated as a link between obesity and breast cancer. In the present study, the effects of leptin on cell proliferation and proteins associated with leptin signaling and/or breast cell growth were investigated in ER-positive, MCF-7, T47-D ...
