Initial treatment with a single capsule containing half-dose quadruple therapy vs standard-dose dual therapy in hypertensive patients (QUADUAL): a randomized, blinded, crossover trial.

Background: Guidelines recognized dual combination in initial antihypertensive therapy. Studies found that low-dose quadruple combination were superior to monotherapy. However, whether low-dose quadruple therapy is better than dual combination is unknown.

Dual Pathways of Photorelease Carbon Monoxide via Photosensitization for Tumor Treatment.

Carbon monoxide (CO) gas therapy, as an emerging therapeutic strategy, is promising in tumor treatment. However, the development of a red or near-infrared light-driven efficient CO release strategy is still challenging due to the limited physicochemical characteristics of the photoactivated carbon monoxide-releasing molecules (photoCORMs). Here, we discovered a novel photorelease CO mechanism that involved dual pathways of CO release via photosensitization.

Carbon nanotube paper with different polymer composition for laser ablation propulsion.

Laser ablation propulsion is an important micro-propulsion system for microsatellites. Polymers with carbon added and carbon-based nanomaterial have been demonstrated as propellants with high impulse coupling coefficient (C). Among them, the carbon nanotube film exhibits a low ablation threshold fluence of 25 mJ/cm, which shows its potential for propulsion under low laser fluence.

High combiner efficiency and self-aligned compact double-sided diffractive waveguide based on linear surface relief gratings.

A diffractive waveguide based on surface relief gratings demonstrates significant potential for augmented reality owing to its ultra-thin and lightweight design, as well as its feasibility for mass production using nanoimprint technology. However, traditional waveguides suffer from low combiner efficiency. To address this issue, we propose what we believe to be a novel double-sided surface relief grating waveguide (abbreviated as double-sided waveguide) with a high combiner efficiency, which comprises a double-sided in-coupler, two single-sided turners, and a double-sided out-coupler.

High anti-Müllerian hormone level as a predictor of poor pregnancy outcomes in women with polycystic ovary syndrome undergoing in vitro fertilization/intracytoplasmic sperm injection: a retrospective cohort study.

Objective: To study the correlation between anti-Müllerian hormone levels and pregnancy outcomes after in vitro fertilization/intracytoplasmic sperm injection in women with polycystic ovary syndrome, which remains controversial.

Methods: This retrospective cohort study recruited 4,719 women with infertility and polycystic ovary syndrome aged 20-40 years who underwent treatment at the Reproductive Center of Peking University Third Hospital between February 2017 and June 2023. We divided the participants into three groups according to the 25th and 75th percentile cutoffs of serum anti-Müllerian hormone: low (≤ 4.
