Deciphering transcription activity of mammalian early embryos unveils on/off of zygotic genome activation by protein translation/degradation.

Quantification of transcription activities in mammalian preimplantation embryos is challenging due to a huge amount of maternally stored transcripts and paucity of research materials. Here, we investigate genome-wide transcription activities of mouse and human preimplantation embryos by quantifying elongating RNA polymerase II. Two transcriptional waves are identified in early mouse embryos, with summits at the 2-cell and 8-cell stages.

Hydroxyl-induced structural defects in metal-organic frameworks for improved photocatalytic decontamination: Accelerated exciton dissociation and hydrogen bonding interaction.

The introduction of structural defects can improve the charge separation efficiency of metal-organic frameworks (MOFs)-based photocatalysts, which however come with suboptimal decontamination performance, due to steric hindrance and limited binding capacity of the involved modulators. In this work, hydroxyl group capturing the advantages of both worlds was utilized as new modulator to improve the photocatalytic performance of Fe-based defective MOFs. Benefited from its low steric effect and strong coordination bonding capability, hydroxyl-induced defects in Fe-MOF contributed to a nearly 8-fold increase of rate constant for the photocatalytic removal of hexavalent chromium (Cr(VI)) compared to that of pristine one, which also exceeded the defective one induced by acetic acid as modulator.

Identification of novel inhibitors targeting PI3Kα via ensemble-based virtual screening method, biological evaluation and molecular dynamics simulation.

PIK3CA gene encoding PI3K p110α is one of the most frequently mutated and overexpressed in majority of human cancers. Development of potent and selective novel inhibitors targeting PI3Kα was considered as the most promising approaches for cancer treatment. In this investigation, a virtual screening platform for PI3Kα inhibitors was established by employing machine learning methods, pharmacophore modeling, and molecular docking approaches.

Associations of Ureaplasma urealyticum infection with male infertility and intrauterine insemination outcomes.

Ureaplasma urealyticum (UU) is one of the most commonly occurring pathogens associated with genital tract infections in infertile males, but the impact of seminal UU infection in semen on intrauterine insemination (IUI) outcomes is poorly understood. We collected data from 245 infertile couples who underwent IUI at The First Affiliated Hospital of USTC (Hefei, China) between January 2021 and January 2023. The subjects were classified into two groups according to their UU infection status: the UU-positive group and the UU-negative group.

Temporal dynamics of immune cell patterns in bladder cancer patients receiving Bacillus Calmette-Guérin therapy.

Background: Bacillus Calmette-Guérin (BCG) is capable of enhancing the infiltration of immune cells into the tumour. However the temporal dynamics of immune cell patterns in patients receiving BCG instillation remains unclear.

Methods: Ninety-six patients who underwent intravesical BCG therapy, comprising 46 responders and 50 non-responders, were retrospectively enroled to explore the evolving immune landscape.

The catalytic performance of (ZrO) ( = 1-4, 12) clusters for Suzuki-Miyaura cross-coupling: a DFT study.

Superatoms are special clusters with similar physicochemical properties to individual atoms in the periodic table, which open up new avenues for exploring inexpensive catalysts. Given that the ZrO superatom possesses the same number of valence electrons as a Pd atom, the mechanisms of the Suzuki-Miyaura reaction catalyzed by (ZrO) ( = 1-4) clusters have been investigated and compared with the corresponding Pd ( = 1-4) species to explore superatom-based catalysts for the formation of C-C bonds a density functional theory (DFT) study. It was interesting to find that the catalytic activities of (ZrO) ( = 1-4) towards the Suzuki-Miyaura reaction gradually improved as the cluster size increased.

To compare the short-term efficacy of laparoscopic sleeve gastrectomy (LSG) combined with sharp His angle reconstruction (LSG-His) versus traditional LSG. In this retrospective cohort study we collected clinical data of patients with obesity who had undergone LSG or LSG-His in the Department of General Surgery, Beijing Chaoyang Hospital, Capital Medical University, from January to June 2022. After excluding patients with incomplete follow-up data and those with hiatal hernia, 83 obese patients, of which 39 who had undergone LSG (LSG group) and 44 who had undergone LSG-His (LSG-His group), were included in the study.

Exploring the effects of an online learning platform in stage III cardiac rehabilitation for individuals with coronary heart disease: Randomized controlled study.

The objective of this study is to assess the influence of blended education methodologies, utilizing an online education platform, among stage III cardiac rehabilitation (CR) patients diagnosed with coronary heart disease (CHD). Between June and August 2021, a cohort of 90 patients diagnosed with CHD, previously discharged from a second-class hospital 1 year earlier, were randomly allocated into 2 groups: the experimental and control groups, with each comprising 45 patients. Patients in the control group received out-of-hospital CR education via WeChat, while those in the experimental group received blended CR education utilizing an online education platform.

Effects of immunosuppression after limb fracture in mice on nociceptive, cognitive, and anxiety-related outcomes.

Introduction: Chronic pain is a common and problematic consequence of injuries with few proven methods for prevention or treatment. In addition to pain, functional limitations and neuropsychiatric changes such as cognitive impairment and anxiety worsen outcomes.

Objectives: To determine whether inhibiting activation of the adaptive immune response after limb fracture would reduce pain, functional loss, memory changes, and anxiety.

Magnetically Enhanced Oxygen Evolution Reaction in Mild Alkaline Electrolytes by Building Catalysts on Magnetic Frame.

Under large current densities, the excessive hydroxide ion (OH) consumption hampers alkaline water splitting involving the oxygen evolution reaction (OER). High OH concentration (≈30 wt.%) is often used to enhance the catalytic activity of OER, but it also leads to higher corrosion in practical systems.
