hepatitis c virus (hcv) encodes two envelope glycoproteins, e1 and e2. our previous work selected a specific aptamer ze2, which could bind to e2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting hcv. in this study, the binding sites between e2 and aptamer ze2 were further explored. e2 was truncated to 15...

conclusions this study revealed that lod in females with pcos with a serum e2 > 40 pg/ml was sufficient and safe to trigger development of ovarian follicles followed by clinical pregnancy. results there was significant difference in the average starting time of ovulation and continuing spontaneous ovulation of cases with pcos with e2 levels > 40 pg/ml, compared with ones with e2 ≤ 40 pg/ml (p =...

This work first showed that the skin anti-inflammatory activities of Eclipta prostrata L. (E. prostrata L.)n be increased through an ultrasonic extraction process at a frequency of 120 kHz with 70% ethanol at 40 ◦C for 6 h. The extract from the ultrasound extraction (UE) contained 378.6 mg/100 g of wedelolactone (a major bioactive substance in E. prostrata L.), compared with the 172.9 mg/100 g ...

BACKGROUND When performing the Valsalva maneuver (VM), adults and preadolescents produce the same expiratory resistance values. OBJECTIVE To analyze heart rate (HR) in preadolescents performing VM, and propose a new method for selecting expiratory resistance. METHOD The maximal expiratory pressure (MEP) was measured in 45 sedentary children aged 9-12 years who subsequently performed VM for ...

Abstract Korean black goat (Capra hircus coreanae) populations are dwindling and facing genetic erosion due to artificial insemination. Here, we introduced an estrus synchronization method for goats enable crossbreeding with non-native breeds on small farms investigated the application of insemination in goats. Semen was obtained using electro-ejaculation preserved a conventional simple freezin...

The aim of the study is to investigate the feasibility of pre-operative autologous blood donation (PABD) self-transfusion on the postpartum recovery and the endocrine in lying-in women. The PABD is carried out on 70 pregnant women who have high risk of postpartum hemorrhage. Those 70 subjects were divided into three groups: 33 cases of PABD self-transfusion during the Cesarean section; 16 cases...

a randomized clinical trial study was undertaken to evaluate the effect of intravenous oxytoxin (50 cases) and intracervical prostaglandin e2 (0.5 mg tab, 50 cases) on the ripening of the cervix and frequency of successful inductions in patients with low bishop score (<5). means of maternal age, gestational age, parity, bs at admission did not show any significant differences between the two gr...

Two possible isomers of some 1,3-diaryl-H-benzo[f]chromene have been studied using density functional theory. Structures of E1 and E2 isomers were optimized at the B3LYP and MP2 levels with different basis sets. The total electronic energies show that E2 isomer is about 3-5 kcal/mol more stable than E1 isomer and this energy difference is attributed to the planarity of heterocyclic ring and mor...

Bisphenol A (BPA) is a synthetic compound widely used in types of consumer goods and medical tools. It has been shown that BPA acts as an endocrine disruptor chemical casuing negative impact on reproductive functions. The present study used an in vitro approach to assess estrogenic transcriptional activity of BPA as a rapid and sensitive method. The cultured pieces of hepatic tissue of goldfish...
