Gene Doping Detection From the Perspective of 3D Genome.

Since the early 20th century, the concept of doping was first introduced. To achieve better athletic performance, chemical substances were used. By the mid-20th century, it became gradually recognized that the illegal use of doping substances can seriously endangered athletes' health and compromised the fairness of sports competitions.

Adsorption of fluorine from lepidolite hydrometallurgy wastewater by aluminum modified zeolite.

Fluoride contamination is a serious environmental problem in lepidolite hydrometallurgy wastewater. The treatment of fluoride-bearing wastewater is challenging because of the presence of coexisting ions including lithium (Li), rubidium (Rb), silicate (SiO), sulfate radical (SO). However, aluminum-modified zeolite (Al@zeolite) with sufficient hydroxyl groups and high adaptability has unique advantages for eliminating fluoride from lepidolite hydrometallurgy wastewater.

Intermittent Vibration Induces Sleep via an Allatostatin A-GABA Signaling Pathway and Provides Broad Benefits in Alzheimer's Disease Models.

While animals across species typically experience suppressed consciousness and an increased arousal threshold during sleep, the responsiveness to specific sensory inputs persists. Previous studies have demonstrated that rhythmic and continuous vibration can enhance sleep in both animals and humans. However, the neural circuits underlying vibration-induced sleep (VIS) and its potential therapeutic benefits on neuropathological processes in disease models remain unclear.

Two-photon pumped forward, backward and random lasing in a stilbazolium dye nanocomposite solution containing LAPONITE® as a scattering center.

Multiphoton upconversion lasing in scattering gain media has attracted considerable attention in recent years. LAPONITE® is a scattering medium consisting of 2-D nano-discs that can be dispersed as a transparent solution in aqueous media and forms a gel at high concentration. In this paper, we demonstrate two-photon pumped upconversion regular lasing along forward and backward directions as well as random lasing along all other directions.

Decoding Missense Variants by Incorporating Phase Separation via Machine Learning.

Computational models have made significant progress in predicting the effect of protein variants. However, deciphering numerous variants of uncertain significance (VUS) located within intrinsically disordered regions (IDRs) remains challenging. To address this issue, we introduce phase separation, which is tightly linked to IDRs, into the investigation of missense variants.

Simulated weightlessness procedure, head-down bed rest has reversible effects on the metabolism of rhesus macaque.

It is a consensus in the international manned space field that factors such as microgravity during the space flight can cause anxiety, depression and other important brain function abnormalities in astronauts. However, the neural mechanism at the molecular level is still unclear. Due to the limitations of research conditions, studies of biological changes in the primate brain have been comparatively few.

The Regulatory Role and Mechanism of Circadian Rhythm in Hemoglobin Co-cultured Neurovascular Unit.

Objective: Intracranial hemorrhage (ICH), the second most common subtype of stroke, exacerbates the disruption of the blood-brain barrier (BBB), leading to vasogenic edema, plasma protein extravasation, and infiltration of neurotoxic substances. The clearance capacity of the brain plays a crucial role in maintaining BBB homeostasis and facilitating patient recovery after hemorrhage. This study aimed to investigate the effect of circadian rhythms on BBB function, neuronal damage, and clearance capabilities.

Association between situs inversus and maternal SARS-CoV-2 infection at gestational age 4-6 weeks.

Background: A dramatic increase in fetal situs inversus diagnoses by ultrasound in the months following the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) surge of December 2022 in China led us to investigate whether maternal SARS-CoV-2 exposure could be associated with elevated risk of fetal situs inversus.

Methods: In this multi-institutional, hospital-based, matched case-control study, we investigated pregnant women who underwent ultrasonographic fetal biometric assessment at gestational weeks 20-24 at our hospitals. Each pregnant woman carrying a situs inversus fetus was randomly matched with four controls based on the date of confinement.

Unraveling schizophrenia's genetic complexity through advanced causal inference and chromatin 3D conformation.

Schizophrenia is a polygenic complex disease with a heritability as high as 80 %, yet the mechanism of polygenic interaction in its pathogenesis remains unclear. Studying the interaction and regulation of schizophrenia susceptibility genes is crucial for unraveling the pathogenesis of schizophrenia and developing antipsychotic drugs. Therefore, we developed a bioinformatics method named GRACI (Gene Regulation Analysis based on Causal Inference) based on the principles of information theory, a causal inference model, and high order chromatin 3D conformation.

pH selects for distinct NO-reducing microbiomes in tropical soil microcosms.

Nitrous oxide (NO), a greenhouse gas with ozone destruction potential, is mitigated by the microbial reduction to dinitrogen catalyzed by NO reductase (NosZ). Bacteria with NosZ activity have been studied at circumneutral pH but the microbiology of low pH NO reduction has remained elusive. Acidic (pH < 5) tropical forest soils were collected in the Luquillo Experimental Forest in Puerto Rico, and microcosms maintained with low (0.

Sustained bacterial NO reduction at acidic pH.

Nitrous oxide (NO) is a climate-active gas with emissions predicted to increase due to agricultural intensification. Microbial reduction of NO to dinitrogen (N) is the major consumption process but microbial NO reduction under acidic conditions is considered negligible, albeit strongly acidic soils harbor nosZ genes encoding NO reductase. Here, we study a co-culture derived from acidic tropical forest soil that reduces NO at pH 4.

Neurobrucellosis: laboratory features, clinical characteristics, antibiotic treatment, and clinical outcomes of 21 patients.

Background: Neurobrucellosis (NB) is a rare and serious complication of brucellosis. Its clinical manifestations vary, with no obvious specificity. At present, there is no clear clinical diagnosis or treatment for reference.

Magnetically driven Janus conical vertical array for all-weather freshwater collection.

The engineering of multifunctional structures with special surface wettability is highly desirable for all-weather freshwater production, but relevant research is scarce. In this study, a Janus conical vertical array was designed and fabricated a magnetically driven spray-coating method for the first time. Benefiting from the special structure and wettability enhancement of the array in terms of solar absorption, fog capture and merging, droplet movement and evaporation area, all-weather freshwater production consisting of high-quality daytime solar vapor generation (water evaporation rate approximately 2.

Macro-porous structured aerogel with enhanced ab/desorption kinetics for sorption-based atmospheric water harvesting.

Sorption-based atmospheric water harvesting (SAWH) has been proven to be a promising method to alleviate the impact of the water crisis on human activities. However, the low water-sorption capacity and sluggish ab/desorption kinetics of current SAWH materials make it difficult to achieve high daily water production. In this study, a photothermal porous sodium alginate-tannic acid-5/Fe@lithium chloride aerogel (SA-TA-5/Fe@LiCl) with macroporous structure (average pore diameter ∼43.

TULP4, a novel E3 ligase gene, participates in neuronal migration as a candidate in schizophrenia.

Background: TUB-like protein 4 (TULP4) is one of the distant members of tubby family proteins, whose function remains largely unknown. In the present study, we intend to identify the role of TULP4 in schizophrenia from human samples and animal models.

Methods: Whole-exome sequencing was used to detect the four schizophrenia families collected.

Population genetics of marmosets in Asian primate research centers and loci associated with epileptic risk revealed by whole-genome sequencing.

The common marmoset ( ) has emerged as a valuable nonhuman primate model in biomedical research with the recent release of high-quality reference genome assemblies. Epileptic marmosets have been independently reported in two Asian primate research centers. Nevertheless, the population genetics within these primate centers and the specific genetic variants associated with epilepsy in marmosets have not yet been elucidated.
