HIV-1 reverse transcriptase (RT) connection subdomain mutations at positions 348, 369 and 376 have been associated with resistance to non-nucleoside RT inhibitors (NNRTIs). N348I may interfere with the initiation of (+)-strand DNA synthesis by reducing polypurine tract (PPT) removal in the presence of nevirapine. The effect of NNRTIs on the RNase H-mediated cleavage of PPT-containing template-p...

Effects of salinity on fertilization, embryonic, and early larval development and growth performances of long-spined black sea urchin (Diademasetosum) were investigated in a controlled laboratory condition. The experiment was carried out with seven salinity treatments (22, 25, 28, 31, 34, 37 and 40ppt), each of which was triplicated. Significantly highest fertilization success was achieved at 3...

Experiments were performed to determine the function of a 28-nucleotide untranslated sequence lying between the envelope gene and the polypurine tract (PPT) sequence in the Moloney murine leukemia virus (Mo-MuLV) genome. A mutant virus carrying a deletion of this sequence (Mo-MuLVDelta28) replicated more slowly than wild-type (wt) virus and reverted by recombination with endogenous sequences du...

Athlete recovery-adaptation is crucial to the progress and performance of highly trained athletes. The purpose of this study was to assess peristaltic pulse dynamic compression (PPDC) in reducing short-term pressure-to-pain threshold (PPT) among Olympic Training Center athletes after morning training. Muscular tenderness and stiffness are common symptoms of fatigue and exercise-induced muscle m...

We investigated the hypothesis that if the area, length, and mineralization of newly formed bone could be used to predict the healing quality of patella-patellar tendon (PPT) junction after partial patellectomy. Twenty-four rabbits underwent partial patellectomy and their PPT complexes of the operated limbs were harvested at weeks 6, 12, and 18 postoperatively. The area, length, and mineralizat...

OBJECTIVE To estimate the pressure pain threshold (PPT) of the craniocervical muscles in women with episodic migraine (EM) n=15 and chronic migraine (CM) n=14, and in healthy volunteers (C) n=15. METHOD A blinded examiner obtained the PPT bilaterally, by pressure algometry, for the following muscles: frontalis, temporalis, masseter, trapezius and sternocleidomastoid. ANOVA (p<0.05) was used f...

This paper defines the amortized entanglement of a quantum channel as the largest difference in entanglement between the output and the input of the channel, where entanglement is quantified by an arbitrary entanglement measure. We prove that the amortized entanglement of a channel obeys several desirable properties, and we also consider special cases such as the amortized relative entropy of e...

The aim of the present study was to investigate effects of short time treatment with estrogen receptor (ER) selective agonists on ERα, ERβ and G-protein coupled estrogen receptor-1 (GPER) expression in the uterus of ovariectomized rats. The rats were treated with either estradiol (E2), the specific ERα agonist PPT or the specific ERβ agonist DPN for 18 hrs. Uterine weights were higher after E2 ...

BACKGROUND Conditioned pain modulation (CPM), a phenomenon also known as diffuse noxious inhibitory control, is thought to be affected by various factors, including sex and level of physical activity. However, the involvement of these factors in CPM remains unclear. METHODS Eighty-six healthy young subjects (M/F, 43/43) participated in this study. Participants were assessed on the basis of th...
