OBJECTIVE To describe the prevalence of the L76V protease inhibitors resistance-associated mutation (PI-RAM) in relation with patients' characteristics and protease genotypic background in HIV-1 B- and "non-B"-infected patients. METHODS Frequency of the L76V mutation between 1998 and 2010 was surveyed in the laboratory database of 3 clinical centers. Major PI-RAMs were identified according to...
The prognostic value of proliferation index (PI) and apoptotic index (AI), caspase-8, -9 and -10 expression have been investigated in primary Ewing's sarcoma family of tumours (ESFT). Proliferating cells, detected by immunohistochemistry for Ki-67, were identified in 91% (91/100) of tumours with a median PI of 14 (range 0-87). Apoptotic cells, identified using the TUNEL assay, were detected in ...
OBJECTIVE To investigate whether the uterine artery pulsatility index (UtA PI) of hypertensive pregnancies is higher than that of normal pregnancies in the puerperium, as well as in the antepartum period. METHODS The UtA PI was measured in hypertensive (group 1) and normal pregnancies (group 2) during antepartum, immediate postpartum or late postpartum periods. Using the transvaginal approach...
The gyromagnetic factor of the low-lying ${E}_{x}=684.10(19)\phantom{\rule{4pt}{0ex}}\mathrm{keV}$ isomeric state nucleus $^{99}\mathrm{Mo}$ was measured using time-dependent perturbed angular distribution technique. This level is assigned a spin and parity ${J}^{\ensuremath{\pi}}=11/{2}^{\ensuremath{-}}$, with half-life ${T}_{1/2}=742(13)\phantom{\rule{0.16em}{0ex}}\mathrm{ns}$. interest popul...
CONTEXT Sustained-release naltrexone implants may improve outcomes of nonagonist treatment of opioid addiction. OBJECTIVE To compare outcomes of naltrexone implants, oral naltrexone hydrochloride, and nonmedication treatment. DESIGN Six-month double-blind, double-dummy, randomized trial. SETTING Addiction treatment programs in St Petersburg, Russia. PARTICIPANTS Three hundred six opioid-addicte...
در این مقاله تحلیل عملکرد کنترلکننده pi، فازی pi، و کنترلکننده موازی فازی + p فازی i برای پایدارسازی فرکانسی لیزرهای هلیوم – نئون با استفاده از ترکیب روشهای متعادلسازی توان و قفل فرکانس ارائه شده است. لیزر هلیوم – نئون را میتوان یک سیستم ناپایدار دانست که فرکانس خروجی آن از عوامل محیطی تاثیر میپذیرد. بنابراین پایدارسازی فرکانسی لیزرهای هلیوم – نئون در کاربردهای ابزاردقیق مانند تداخلسنجه...
In this paper, the $IJ=00, 11, 20$ partial wave $\pi\pi$ scattering phase shifts determined by lattice QCD approach are analyzed using a novel dispersive solution of S-matrix, i.e. PKU representation, in which unitarity and analyticity amplitudes automatically satisfied conveniently decomposed into contributions cuts various poles, including bound states, virtual states resonances. The contribu...
