BackgroundThe National Health and Family Planning Commission of China (NHFPCC) issued the “Measures for the Management of Human Sperm Banks,” which was revised in 2003 and is still in effect today. One of the standard guidelines is that potential donors undergo laboratory testing to exclude infectious and genetic diseases and karyotype analysis. However, patient demands for donor genetic testing have also increased, and only karyotype analysis to exclude genetic diseases is not sufficient to meet these demands.ObjectiveTo examine donor genetic screening practices at sperm banks in China and to evaluate the qualifications and skills of genetic counselors at the banks.Materials and methodsAn electronic survey was distributed to twenty-seven sperm banks to examine donor genetic screening practices at sperm banks in China and to evaluate the qualifications and skills of genetic counselors at the banks. Twenty-six human sperm banks responded to a 32-question survey about their current practices related to genetic testing of sperm donors.ResultsThe 26 sperm banks reported that all qualified sperm donors undergo karyotype analysis; 22 banks (84.6%) collected three generations of family history from each qualified sperm donor; 10 (38.5%) reported that they attempted to accommodate special requests from donor semen recipients for particular genetic tests. Only 2 of the 26 (7.7%) sperm banks reported that they performed whole-exome sequencing. At all the sperm banks, consent for genetic testing was obtained as part of the overall contract for sperm donors. Nineteen (73.1%) sperm banks had genetic counselors on their staff, while six (23.1%) had no genetic counselors on their staff but had access to genetic counselors at the hospital. Only one (3.8%) sperm bank had no genetic counselors on their staff or at the hospital.ConclusionsThe need for larger scale genetic testing of donors and recipients and an extensive panel of genetic tests specific to the Chinese population. Additionally, professionally trained geneticists must be employed as genetic counsellors so that the results of genetic tests and their implications can be explained to donors.

BackgroundTo explore the underlying mechanism of programmed cell death (PCD)-related genes in patients with endometrial cancer (EC) and establish a prognostic model.MethodsThe RNA sequencing data (RNAseq), single nucleotide variation (SNV) data, and corresponding clinical data were downloaded from TCGA. The prognostic PCD-related genes were screened and subjected to consensus clustering analysis. The two clusters were compared by weighted correlation network analysis (WGCNA), immune infiltration analysis, and other analyses. The least absolute shrinkage and selection operator (LASSO) algorithm was used to construct the PCD-related prognostic model. The biological significance of the PCD-related gene signature was evaluated through various bioinformatics methods.ResultsWe identified 43 PCD-related genes that were significantly related to prognoses of EC patients, and classified them into two clusters via consistent clustering analysis. Patients in cluster B had higher tumor purity, higher T stage, and worse prognoses compared to those in cluster A. The latter generally showed higher immune infiltration. A prognostic model was constructed using 11 genes (GZMA, ASNS, GLS, PRKAA2, VLDLR, PRDX6, PSAT1, CDKN2A, SIRT3, TNFRSF1A, LRPPRC), and exhibited good diagnostic performance. Patients with high-risk scores were older, and had higher stage and grade tumors, along with worse prognoses. The frequency of mutations in PCD-related genes was correlated with the risk score. LRPPRC, an adverse prognostic gene in EC, was strongly correlated with proliferation-related genes and multiple PCD-related genes. LRPPRC expression was higher in patients with higher clinical staging and in the deceased patients. In addition, a positive correlation was observed between LRPPRC and infiltration of multiple immune cell types.ConclusionWe identified a PCD-related gene signature that can predict the prognosis of EC patients and offer potential targets for therapeutic interventions.

Objetivo desse estudo foi identificar e descrever os principais sintomas apresentados pela Síndrome Pós-COVID-19.Trata-se de uma pesquisa descritiva, de Revisão Bibliográfica, dando prioridade às publicações no período de 2019 a 2022. As buscas das fontes foram realizadas por meio bases de dados, Scielo e Google acadêmico, visando a recuperação de artigos que foram selecionados por meio das seguintes palavras-chave: Fadiga muscular, cefaleia e Covid-19. Os resultados encontrados apontam que os principais sintomas que permaneceram após a infecção pela covid-19, foram: fadiga, ageusia, anosmia e cefaleia. A fadiga apresentou uma maior incidência em pacientes que permaneceram em longos períodos sob tratamento em unidade de terapia intensiva. Em relação às alterações de olfatos e paladar, a colonização do vírus no sistema nasofaringe acaba acometendo suas funções devido a atividades de enzinas, que, posteriormente, tendem a adentrar ao Sistema Nervoso Central (SNC) gerando comprometimento em funções neurológicas e causando sinais e sintomas como a cefaleia, que também teve grande incidência no período pós-covid. Concluimos que os principais sintomas na Síndrome Pós-COVID-19 foram: fadiga muscular, cefaleia, perda do paladar e do olfato. Identificamos também que, após a fase aguda da doença, alguns pacientes permaneceram com sintomas mais graves, sendo que estes tiveram maior comprometimento no sistema neurológico, cardiovascular, pulmonar e neurológico. Por se tratar de uma condição recentemente descoberta na visão científica, são necessários novos estudos sobre o tema, além do devido acompanhamento em relação às novas descobertas sobre a doença.

AbstractRare earth elements (REEs) are essential for many clean energy technologies. Yet, they are a limited resource currently obtained through carbon‐intensive mining. Here, bio‐scaffolded proteins serve as simple, effective materials for the recovery of REEs. Surface expression of the protein lanmodulin (LanM) on E. coli, followed by freeze‐drying of the microbes, yields a displayed protein material for REE recovery. Four REE cations (Y3+, La3+, Gd3+, and Tb3+) are captured efficiently, with over 80% recovery even in the presence of competitive ions at one‐hundred‐fold excess. Moreover, these materials are readily integrated into a filter with high capture capacity (12 mg g−1 dry cell weight) for the selective isolation and recovery of REEs from complex matrices. Further, the proteins in the filter remain stable over ten bind‐and‐release cycles and a week of storage. To improve the deployability of this filter material, a simple colorimetric assay with the dye alizarin‐3‐methyliminodiacetic acid is incorporated. The assay can be performed in under 5 min, enabling rapid monitoring of REE recovery and filter efficiency. Overall, this low‐cost, robust material will enable environmentally friendly recycling and recovery of critical elements.

AbstractThe remarkable toughness (>70 MJ m−3) of silkworm silk is largely attributed to its hierarchically arranged nanofibrillar nanostructure. Recreating such tough fibers through artificial spinning is often challenging, in part because degummed, dissolved silk is drastically different to the unspun native feedstock found in the spinning gland. The present work demonstrates a method to dissolve silk without degumming to produce a solution containing undegraded fibroin and sericin. This solution exhibits liquid‐liquid phase separation above 10% (wt/wt), a behavior observed in the silk gland but not in degummed silk solutions to date. This partitioning enhances the stability of the undegummed solution, delaying gelation two‐fold compared with degummed silk at the same concentration. When spun under identical conditions, undegummed solutions produces fibers 8× stronger and 218× tougher than degummed silk feedstocks. Through ultrasonication, undegummed wet spun fibers are seen to possess hierarchical structure of densely packed ≈20 nm nanofibrils, similar to native silks, although completely absent from fibers wet‐spun from degummed silk solutions. This work demonstrates that the preservation of molecular weight, presence of sericin and stimulation of liquid‐liquid phase separation underpin a new pathway to recreate a hierarchical fiber with structures akin to native silk.
Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring

Published: January 2025

AbstractConventional microscopy‐driven sperm health monitoring systems suffer from high infrastructural costs and complex protocols. Here, a simple, economical sperm motility assessment system is proposed. Based on a cantilever‐deflection‐based direct force measurement system capable of detecting wetting forces in the range of ≈µN, it is found that the adhesion of live and motile sperm cell‐laden droplets is dependent on sperm motility in the suspension. Further, it is observed that the sperm motility inside the droplet decreases with time, and the adhesion of the concerned droplet with a master substrate demonstrates an increasing trend. Contrary to an immotile cell, the motile sperm, due to its inherent nature of swimming parallel to the contact line, induces a lower restrictive force on the receding triple contact line of the droplet. The study establishes a potential avenue by which sperm cell motility can be predicted via measuring the adhesion of the sperm‐cell‐laden droplets with a standard surface using the simple and automatable cantilever‐deflection method. These findings can pave a pathway toward developing a user‐friendly, expertise‐independent diagnostic platform for in‐house sperm health monitoring.

Published: January 2025

AbstractMultiple resonance thermally activated delayed fluorescence (MR‐TADF) materials offer narrowband emission and efficiency but suffer from spectral broadening and aggregation‐caused quenching (ACQ) at high doped concentrations. In this study, two novel silicic linkage‐based dual‐core MR‐TADF emitters, DMeSiB and DPhSiB, are introduced, which effectively mitigate both concentration quenching and spectral broadening. DMeSiB and DPhSiB exhibit bluish‐green emission peaking at 493 and 495 nm with full‐width at half‐maximum (FWHM) values of 21 and 22 nm in toluene and high photoluminescence quantum yields exceeding 90% in doped films. At a doping concentration of 5 wt%, the organic light‐emitting diodes (OLEDs) based on DMeSiB and DPhSiB achieve maximum external quantum efficiencies (EQEmaxs) of 27.2% and 28.6% with narrow FWHMs of 25 and 24 nm, respectively. Over a doping concentration range of 5 wt% to 20 wt%, the OLEDs maintain high EQEmax values of 23.5%, 21.4%, 19.2% and 24.9%, 22.7%, 19.3%, respectively. Even at a 20 wt% doping concentration, the FWHMs of the devices broaden by only 2 or 3 nm, reaching 27 nm. This structural design facilitates efficient luminescence while successfully suppressing spectral broadening and ACQ, leading to improved device performance.

AbstractLithium is becoming increasingly important due to its indispensable role in lithium‐ion batteries. The direct extraction of lithium from salt lakes, which are a main source of lithium, is challenging due to the coexistence of many interfering alkali and alkaline earth metals. In this work, we report that a synergistic solvent extraction (SSX) system containing 2,9‐dialkyl‐1,10‐phenanthroline and a hydrophobic anion ([NTf2]−) could extract lithium selectively with a high lithium loading capacity from solutions containing both alkali (sodium, potassium) and alkaline earth metals (magnesium, calcium), enabling the direct recovery of lithium from complex salt lakes. The outstanding lithium extraction performance of the SSX system is unprecedented, to the best knowledge of the authors. Through various characterizations and X‐ray diffraction of the complex crystals, the extraction mechanism has been revealed. This SSX system will potentially promote more efficient recovery of lithium from salt lakes.
