Introduction: (UU) is a common pathogen associated with genital tract infections in infertile males. However, its impact on semen quality, embryo development, and fertilization (IVF) outcomes remains underexplored. This study aims to evaluate the effect of male UU infection on semen parameters, embryo development, pregnancy outcomes, and neonatal health in infertile couples.

Herein, we overcome this challenge by constructing the NiFe hydroxide/NiMo alloy (NiFe-LDH/NiMo) heterojunction electrocatalyst, featuring the NiMo alloy as the oxygen pump to provide oxygenous intermediates and electrons for NiFe-LDH. The released lattice oxygen can be timely offset by the oxygenous species during the LOM process, balancing the regeneration of lattice oxygen and assuring the enhancement of the durability.

However, the protective mechanism of OMT on NSAID-associated small bowel mucosal injury remains unreported. We found that OMT could improve the clinical symptoms and pathological inflammation scoring, reduce the secretion of proinflammatory cytokines IL-1β, IL-6 and TNF-α and cell apoptosis, promote cell proliferation and protect intestinal mucosal barrier as compared with the Diclofenac Sodium (DS) group.

Understanding emotions from diverse contexts has received widespread attention in computer vision communities. The core philosophy of Context-Aware Emotion Recognition (CAER) is to provide valuable semantic cues for recognizing the emotions of target persons by leveraging rich contextual information. Current approaches invariably focus on designing sophisticated structures to extract perceptually critical representations from contexts.

Methods: In this study, 100 patients who underwent patella fracture surgery at Peking University People's Hospital between April 2018 and December 2019 were randomly selected and divided into a control group (n=50) and an experimental group (n=50) by lottery. The control group received exercise therapy, while the experimental group received alfacalcidol based on exercise rehabilitation.
Objective: To investigate the association of serum MMP-2, Siglec-1, and Th1/Th2 cell ratio with disease activity in rheumatoid arthritis (RA).
Methods: Between August and November 2020, Peking University People's Hospital recruited 40 patients with RA and 40 healthy individuals. Various methods such as ELISA, flow cytometry, and RT-PCR were used to assess the levels of sCR1, MMP-2, MMP-9, and Siglec-1 in the participants.
Animal models of authentic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection require operation in biosafety level 3 (BSL-3) containment. In the present study, we established a mouse model employing a single-cycle infectious virus replicon particle (VRP) system of SARS-CoV-2 that can be safely handled in BSL-2 laboratories. The VRP [ΔS-VRP(G)-Luc] contains a SARS-CoV-2 genome in which the spike gene was replaced by a firefly luciferase (Fluc) reporter gene (Rep-Luci), and incorporates the vesicular stomatitis virus glycoprotein on the surface.
