Understanding adherence to continuous positive airway pressure in patients with obstructive sleep apnea post-stroke: A prospective study based on the Andersen model.

Adherence to continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) post-stroke is often problematic, despite potential benefits. This study aimed to evaluate CPAP adherence in patients with OSA post-stroke based on the Andersen behavioral model of health services utilization. A total of 227 eligible participants were recruited from a Chinese hospital.

Clinical Application of Noninvasive Prenatal Testing for Pregnant Women with Assisted Reproductive Pregnancy.

Objective: This paper analyzes the clinical significance of noninvasive prenatal testing (NIPT) for fetal chromosome aneuploidy in the screening of in vitro fertilization-embryo transfer (IVF) pregnancies.

Methods: The study subjects consisted of 3163 IVF-pregnant women who underwent NIPT at the Women's Hospital, School of Medicine, Zhejiang University and Taizhou Hospital, Zhejiang Province from February 2015 to June 2019. Fetal or neonatal karyotype analysis was carried out in high-risk patients, with subsequent follow-up on pregnancy outcomes.

Transient thermal effect, nonlinear refraction and nonlinear absorption properties of graphene oxide sheets in dispersion.

The nonlinear refraction (NLR) properties of graphene oxide (GO) in N, N-Dimethylformamide (DMF) was studied in nanosecond, picosecond and femtosecond time regimes by Z-scan technique. Results show that the dispersion of GO in DMF exhibits negative NLR properties in nanosecond time regime, which is mainly attributed to transient thermal effect in the dispersion. The dispersion also exhibits negative NLR in picosecond and femtosecond time regimes, which are arising from sp(2)- hybridized carbon domains and sp(3)- hybridized matrix in GO sheets.

Hepal-6 derived RNA electroporated murine spleen B cells induced antitumor effects in vivo.

RNA electroporated CD40 ligand-activated B cells can induce cytotoxic T-lymphocyte response in vitro. In order to evaluate the effects in vivo, we applied murine spleen B cell vaccine in a mouse model of liver cancer. C57BL/6 mouse spleen B cells were activated by anti-mouse CD40 antibody, recombinant interleukin-4, and cyclosporin A, and then electroporated with total RNA from Hepal-6 cells (Hepal-6 RNA-CD40mAb-B cells).

Porphyrin and fullerene covalently functionalized graphene hybrid materials with large nonlinear optical properties.

The nonlinear optical properties of two novel graphene nanohybrid materials covalently functionalized with porphyrin and fullerene were investigated by using the Z-scan technique at 532 nm in the nanosecond and picosecond time scale. Results show that covalently functionalizing graphene with the reverse saturable absorption chromospheres porphyrin and fullerene can enhance the nonlinear optical performance in the nanosecond regime. The covalently linked graphene nanohybrids offer performance superior to that of the individual graphene, porphyrin, and fullerene by combination of a nonlinear mechanism and the photoinduced electron or energy transfer between porphyrin or fullerene moiety and graphene.

[Impact of NO in peritoneal fluid on sperm motility in patients with endometriosis].

Objective: To determine the level of NO in the peritoneal fluids in patients with endometriosis and to evaluate the impact of NO on human sperm motility.

Methods: Peritoneal fluids were taken from 19 patients with Endometriosis, 16 infertile patients with Endometriosis, and 21 patients without Endometriosis (control group). The macrophages in the peritoneal fluids were segregated and cultivated.

[Impact of progesterone in peritoneal fluid on sperm motility in infertile patients with endometriosis].

Objective: To evaluate the impact of progesterone in the peritoneal fluid on human sperm motility in the infertile patients with endometriosis.

Methods: Peritoneal fluids were collected from 41 patients by laparoscopy, of which 17 were infertile patients with endometriosis, 11 were fertile patients with endometriosis and 13 were fertile controls. The concentrations of progesterone in the peritoneal fluids were measured by the immulyze-enzyme amplified luminescence system.
