Deoxyribonucleoside triphosphate pools in uninfected and herpes simplex virus type 1 (HSV-1)- and HSV-2-infected KB cells were analyzed to determine whether ribonucleotide reductase functions in vivo in the presence and absence of thymidine (TdR). Previously we showed that HSV-2 replication was inhibited in KB cells blocked in their capacity to synthesize DNA by TdR. HSV-1 replication was not i...
BACKGROUND Surveillance for HIV transmitted drug resistance (TDR) is performed using HIV genotype results from individual specimens. Pyrosequencing, through its massive parallel sequencing ability, can analyze large numbers of specimens simultaneously. Instead of using pyrosequencing conventionally, to sequence a population of viruses within an individual, we interrogated a single combined pool...
BACKGROUND Numerous studies have shown that baseline drug resistance patterns may influence the outcome of antiretroviral therapy. Therefore, guidelines recommend drug resistance testing to guide the choice of initial regimen. In addition to optimizing individual patient management, these baseline resistance data enable transmitted drug resistance (TDR) to be surveyed for public health purposes...
BACKGROUND Anterior cervical discectomy and fusion (ACDF) is the gold standard for treating symptomatic cervical disc degeneration. Cervical total disc replacements (TDRs) have emerged as an alternative for some patients. The purpose of this study was to evaluate the safety and effectiveness of a new TDR device compared with ACDF for treating single-level cervical disc degeneration. METHODS T...
Report of the joint TDR/EC expert consultation to evaluate the potential roles of biomarkers in the management of HIV-infected and HIV-uninfected patients with tuberculosis Report of the joint TDR/EC expert consultation to evaluate the potential roles of biomarkers in the management of HIV-infected and HIV-uninfected patients with tuberculosis Joint TDR/EC expert consultation on biomarkers in t...
Study design: In-vitro biomechanical study. Objective: To characterize cervical TDR kinematics above 2-level fusion, and to determine the effect of fusion alignment on TDR response. Summary of Background Data: Cervical total disc replacement (TDR) may be a promising alternative for a symptomatic adjacent level after prior multi-level cervical fusion. However, little is known about the TDR kinem...
استمرار خشکسالیهای اخیر استان آذربایجانشرقی باعث کاهش چشمگیر منابع آبی قابل دسترس شده و در همین زمان، سطح زیر کشت باغات و اراضی زراعی بهصورت بیرویه و نامتناسب با تغییرات اقلیمی توسعه پیدا کرده است. از آنجایی که بالاترین میزان مصرف آب مربوط به بخش کشاورزی است، لذا تحقیق در زمینه استفاده از منابع آب جایگزین و روشهای صرفهجویی در مصرف بهینه آن بسیار ضروری است. امروزه، استحصال آب باران یکی از...
گیاه سیاهتاغ(Haloxylon aphyllum) بهعنوان یکی از مهمترین گونههای مورد استفاده در تثبیت ماسههایروان و بیابانزدایی، در سطح وسیعی از اراضی بیابانی ایران کاشت شده است. توجه به نیازهای این گیاه، ازجمله نیاز آبی آن، برای استقرار و پایداری بلندمدت، امری ضروری است. در این تحقیق عکسالعمل اجزاء زیست توده، نسبت شاخه به ریشه (S/R)، حجم تاج پوشش گیاه و در نهایت نیاز آبی آن، در شرایط طبیعی با استفاده...
Loss of the protective function of telomeres has previously been hypothesized to cause a DNA damage response. Here, we report a genome-wide expression response, the telomerase deletion response (TDR), that occurs when telomeres can no longer be maintained by telomerase. The TDR shares features with other DNA damage responses and the environmental stress response. Unexpectedly, another feature o...
In male reproductive development in plants, meristemoid precursor cells possessing transient, stem cell-like features undergo cell divisions and differentiation to produce the anther, the male reproductive organ. The anther contains centrally positioned microsporocytes surrounded by four distinct layers of wall: the epidermis, endothecium, middle layer, and tapetum. Here, we report that the ric...
