Beta Irradiation Effects on Electrical Characteristics of Graphene-Doped PVA/n-type Si Nanostructures.

This study investigates the beta irradiation's impact on the electrical features of interfacial nanostructures composed of poly(vinyl alcohol) (PVA) doped with graphene. The integration of graphene, a 2D carbon allotrope renowned for its exceptional electrical conductivity, into PVA nanostructures holds significant promise for advanced electronic applications. Beta irradiation, as a controlled method of introducing radiation, offers a unique avenue to modulate the properties of these nanostructures.

Comparison of the rates for reaching the blastocyst stage between normal and abnormal pronucleus embryos monitored by a time-lapse system in IVF patients.

Objective: To compare the rates of blastocyst stage development between embryos fertilized after one (MPN) or more than two pronucleus (PN) (3PN, 4PN-multiPN) with those after 2PN in the same patients.

Material And Methods: The embryos of patients who had both abnormal PN (MPN, 3PN or 4PN) and normal fertilized (2PN) embryos after intracytoplasmic sperm injection (ICSI) fertilization, were followed with a time-lapse system following the ICSI procedure. The rates of reaching the blastocyst stage were compared between normal and abnormally fertilized embryos.

IVF outcomes after hysteroscopic metroplasty in patients with T- shaped uterus.

Background: T- shaped uterus may be associated with infertility and adverse pregnancy outcomes. Hysteroscopic metroplasty may improve the reproductivity for these cases. To our knowledge, there is no data in literature about the clinical consequences of in vitro fertilization (IVF) in patients undergoing hysteroscopic metroplasty for T-shaped uterus.

Anesthesia in multiple sclerosis and obstructive sleep apnea: case report and literature review.

While patients with obstructive sleep apnea (OSA) or multiple sclerosis (MS) are at high risk of developing postoperative complications, both of them have special anesthetic considerations in intraoperative and postoperative periods. A careful preoperative evaluation, use of the optimal anesthetic regimen and close postoperative care is essential for these patients. Rarity of coexistence of both obstructive sleep apnea and multiple sclerosis in a surgical patient necessitates careful anesthetic management.

Placental volume and vascularization flow indices by 3D power Doppler US using VOCAL technique and correlation with IGF-1, free beta-hCG, PAPP-A, and uterine artery Doppler at 11-14 weeks of pregnancy.

Aims: The purpose of this study was to investigate correlations between first trimester placental volume (PV) and blood flow indexes (FIs), bilateral uterine artery pulsatility indexes, notching, and biochemical parameters: pregnancy-associated plasma protein-A (PAPP-A), free beta-human chorionic gonadotropin (f-β-hCG), and insulin-like growth factor-1 (IGF-1) to predict the high-risk pregnancies in the first trimester.

Methods: We prospectively examined 310 patients at 11-14 weeks of pregnancy using transabdominal 3D gray scale and power Doppler ultrasound for assessing PV, vascularization index, FI, and vascularization FI (VFI). The acquired volumes were analyzed using VOCAL™ imaging software.

Spontaneous perforation of pyometra.

Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01-0.

Exposure to low outdoor temperature in the midtrimester is associated with low birth weight.

Background: Although seasonal variation of birth weight has been reported previously, contributing factors such as the meteorological factor and its specific period of exposure remain unclear.

Aim: To investigate the effect of season on birth weight and to determine the meteorological factor and its specific period of exposure which can contribute to any seasonal variation in birth weight.

Methods: Retrospective analysis of 3333 singleton live births after 36 completed weeks of pregnancy.
