Article Synopsis
  • Infertility affects millions and treatments like IVF and ICSI have low success rates (~35% per embryo transfer), prompting researchers to examine how lifestyle factors, particularly sleep, may impact outcomes.
  • A study with 174 women undergoing ART explored the link between sleep quality, stress levels, and the success of IVF/ICSI procedures by analyzing various reproductive metrics.
  • Results indicated that poor sleep quality significantly reduced the number of retrieved oocytes and matured oocytes, with excessive sleep (≥10 hours) leading to even worse outcomes in embryo quality.

Article Synopsis
  • Cadmium (Cd) is a trace metal essential for marine life but can be toxic in high amounts, affecting phytoplankton growth and its distribution closely follows that of phosphate (PO), though the reasons are not fully clear.
  • A study used advanced machine learning methods to create a detailed global dataset of dissolved cadmium (dCd), finding that the random forest algorithm was the most effective in accurately predicting dCd distribution.
  • The study revealed that the variability in Cd levels is shaped by biological processes in surface waters, mineralization in deeper seas, and how seawater layers mix, with a significant amount coming from high-nutrient, low-chlorophyll (HNLC) regions.

The indistinguishable photon-pair sources are valuable in many quantum information applications, such as quantum microscopy, quantum synchronization, and quantum metrology. Based on cascaded sum-frequency generation (SFG) and spontaneous parametric downconversion (SPDC) processes, we propose and demonstrate a scheme for the generation of spatially separated broadband indistinguishable photon pairs in the telecom band by using only one piece of a fiber-pigtailed periodically poled lithium niobate waveguide in a modified Sagnac loop. The measured joint spectral intensity of the generated entangled photon pairs is 7.

Epitaxy of rare-earth nitride films are crucial for studying their physical properties and offer significant potential for applications in spintronics and optoelectronics. However, synthesizing single-crystalline LuN presents significant challenges, leading to a limited understanding of its properties. In this study, we successfully achieved the epitaxial growth of (001)-oriented LuN films on YAlO (110) substrates by reactive magnetron sputtering epitaxy.

Purpose: To investigate the outcomes and risk factors for patients with hematologic malignancies (HM) following late-stage SARS-CoV-2 infection.

Background: Patients with HM such as lymphoproliferative malignancies (including acute lymphoblastic leukemia and multiple myeloma) and myeloproliferative malignancies (including acute myeloid leukemia, myeloproliferative neoplasm, and myelodysplastic syndrome) are at increased risk of severe illness and high mortality from COVID-19. This study examines the impact of SARS-CoV-2 infection severity on HM prognosis during the late phase of COVID-19, using data from 203 patients at Shanxi Bethune Hospital.

Glioma is one of the most common primary malignant tumors of the central nervous system, and the prognosis is getting worse with the improvement of tumor grade. In recent years, with the in-depth study of the disease, researchers have found that microvascular mimicry seems to be the key factor of poor prognosis, but its specific mechanism has not been thoroughly studied, and the expression of microvascular mimicry in high-grade gliomas is closely related to the expression of NDRG1 gene. This research project is expected to control the occurrence and development of HGG by exploring the factors that affect the expression of NDRG1 gene.

This study aimed to explore the dissemination of HIV/AIDS-related information and risk factors on social media during AIDS Weeks, helping policymakers and public health organizations understand how the public utilizes social media to formulate strategies for AIDS health campaigns better. This study used Latent Dirichlet Allocation (LDA) topic modeling and sentiment analysis to investigate the distribution of themes and people's reactions during AIDS Weeks. Additionally, Critical Discourse Analysis (CDA) was employed to further examine the social structures, cultural contexts, and power dynamics underlying the discourse.

Making use of novel materials to develop efficient catalysts is one of the research hotspots for CO hydrogenation to methanol. Herein, UiO-66, a typical Zr-MOF, was modified by ethylene diamine tetraacetic acid (EDTA) to serve as a substrate for the synthesis of AuCu bimetallic catalysts. The resultant AuCu@UiO-66-EDTA catalyst exhibited a superior methanol production rate, which delivered a high space-time yield of methanol (3.

The stratum corneum of the skin functions as a barrier, obstructing drug absorption and complicating the treatment of skin infections caused by pathogens such as bacteria, fungi, and viruses through topical methods. In this research, a microneedle patch was developed, which consists of gelatin-sucrose (SG) that encapsulates polydopamine-copper nanoparticles (PDA@Cu) at the tip for antibacterial purposes. Poly(ethylene glycol) diacrylate (PEGDA) served as the primary substrate for the microneedle shaft (PDA@Cu-SG/PEGDA).

Duplication of methyl-CpG-binding protein 2 (MECP2) gene causes MECP2 duplication syndrome (MDS). To normalize the duplicated MECP2 in MDS, we developed a high-fidelity Cas13Y (hfCas13Y) system capable of targeting the MECP2 (hfCas13Y-gMECP2) messenger RNA for degradation and reducing protein levels in the brain of humanized MECP2 transgenic mice. Moreover, the intracerebroventricular adeno-associated virus (AAV) delivery of hfCas13Y-gMECP2 in newborn or adult MDS mice restored dysregulated gene expression and improved behavior deficits.

The target of rapamycin (TOR) kinase is a central signaling hub that plays a crucial role in precisely orchestrating plant growth, development, and stress responses. This suggests that TOR is intricately involved in maintaining the balance between plant growth and stress responses. Nevertheless, despite the observed effects, the specific mechanisms through which TOR operates in these processes remain obscure.
