Copy number variants (CNVs) are prevalent in both diploid and haploid genomes, with the latter containing a single copy of each gene. Studying CNVs in genomes from single or few cells is significantly advancing our knowledge in human disorders and disease susceptibility. Low-input including low-cell and single-cell sequencing data for haploid and diploid organisms generally displays shallow and highly non-uniform read counts resulting from the whole genome amplification steps that introduce amplification biases.

Objective: To develop an appropriate intervention utilizing acceptance and commitment therapy (ACT) tailored specifically for cancer patients undergoing radiotherapy, and to investigate its impact on hope, psychological resilience, psychological flexibility, and psychological distress among cancer patients receiving proton and heavy ion therapy.

Methods: Eighty participants were allocated into an intervention group (n = 40) or a control group (n = 40) based on their admission time. The control and intervention groups underwent a 3-week health education program, with the intervention group additionally participating in a 3-week, 6-session acceptance and commitment therapy (ACT) group psychological intervention.

Article Synopsis
  • The study highlights the ongoing challenges faced by ulcerative colitis (UC) patients in Japan despite existing treatments, focusing on their health-related quality of life (HRQoL) and productivity losses.
  • About 83.6% of participants were on non-biologic treatments, with a significant portion reporting persistent symptoms and a notable percentage experiencing anxiety and depression, which negatively impacted their work productivity by an average of 29.3%.

Introduction: Studies using cross-sectional data or with a short follow-up period fail to distinguish whether the associations between sleep duration and physical activity with cognitive function result from reverse causation.

Methods: The longitudinal study examined the individual and joint associations, with specific temporality, between sleep duration and physical activity with cognitive function, using time-lagged linear mixed models and generalized additive mixed models.

Results: A total of 14,694 participants aged ≥ 50 years were included, with an average lagged time of 4.

Tartary buckwheat, a protein-rich pseudocereal with anti-diabetic effects, has not yet been fully explored as a source of dipeptidyl peptidase-IV (DPP-IV) inhibitory peptides. This study aims to discover novel DPP-IV inhibitory peptides from tartary buckwheat protein (TBP). Five hydrolysis methods were employed, with simulated gastrointestinal digestion (SGID) releasing the most active DPP-IV inhibitory hydrolysates, showing both the highest degree of hydrolysis (22.

Hypoxia will accelerate tumors metastasis and deterioration, thereby limiting the effects of chemotherapy or radiotherapy. Thus, developing efficient techniques for detecting hypoxia in tumor cells is extremely important for cancer diagnosis and therapy. In this work, we reported a dicyanoisophorone-based probe (DCI-Azo) that specifically switched on its near infrared emission with hypoxia up-regulated azo-reductase (AzoR).

The emergence of spatial transcriptomic technologies has opened new avenues for investigating gene activities while preserving the spatial context of tissues. Utilizing data generated by such technologies, the identification of spatially variable (SV) genes is an essential step in exploring tissue landscapes and biological processes. Particularly in typical experimental designs, such as case-control or longitudinal studies, identifying SV genes between groups is crucial for discovering significant biomarkers or developing targeted therapies for diseases.

Article Synopsis
  • The study aimed to explore how Anti-ganglioside GM1 antibodies (Anti-GM1) affect the natural killer (NK) cells' ability to kill cancer cells in nude mice by altering their differentiation.
  • Researchers used a detailed staining method to identify NK cell characteristics in kidney cancer tissues and immunized mice with GM1 to produce Anti-GM1.
  • The results showed that Anti-GM1 significantly reduced NK cell activity, promoted their maturation, and decreased key signaling molecules (IFN-γ and GzmB) involved in their killing function compared to a control group.

As more multi-ancestry GWAS summary data become available, we have developed a comprehensive trans-ancestry pathway analysis framework that effectively utilizes this diverse genetic information. Within this framework, we evaluated various strategies for integrating genetic data at different levels-SNP, gene, and pathway-from multiple ancestry groups. Through extensive simulation studies, we have identified robust strategies that demonstrate superior performance across diverse scenarios.

Background: Exercise is recognized for its broad health benefits, influencing various physiological processes, including the behavior of adipose tissue macrophages (ATMs). While existing studies mainly associate ATM activity with obesity and metabolic syndrome, our study explores the impact of aerobic exercise on ATM microRNA expression profiling in a non-obese context, highlighting its general health-promoting mechanisms.

Methods: Sixty male C57BL/6 mice were randomly assigned to either a sedentary (S) or an exercise (E) group.

Topological properties of energy flow of light are fundamentally interesting and may introduce novel physical phenomena associated with directional light scattering and optical trapping. In this Letter, skyrmionlike structures formed by Poynting vectors are unveiled in the focal region of two pairs of counterpropagating cylindrical vector vortex beams in free space. The appearance of local phase singularities, and the distinct traveling and standing wave modes of different field components passing through the focal spot lead to a Néel-Bloch-Néel transition of Poynting vector skyrmion textures along the light propagating direction.

Organic electrochemical transistors (OECTs) can be used to create biosensors, wearable devices and neuromorphic systems. However, restrictions in the micro- and nanopatterning of organic semiconductors, as well as topological irregularities, often limit their use in monolithically integrated circuits. Here we show that the micropatterning of organic semiconductors by electron-beam exposure can be used to create high-density (up to around 7.

Imaging Photoplethysmography (IPPG) is an emerging and efficient optical method for non-contact measurement of pulse waves using an image sensor. While the contactless way brings convenience, the inevitable distance between the sensor and the subject results in massive specular reflection interference on the skin surface, which leads to a low Signal to Interference plus Noise Ratio (SINR) of IPPG. To ease this challenge, this work proposes a novel modulation illumination approach to measure the accurate arterial pulse wave via surface reflection interference isolation from IPPG.

The autonomic nervous system (ANS) plays a critical role in regulating not only cardiac functions but also various other physiological processes, such as respiratory rate, digestion, and metabolic activities. The ANS is divided into the sympathetic and parasympathetic nervous systems, each of which has distinct but complementary roles in maintaining homeostasis across multiple organ systems in response to internal and external stimuli. Early detection of ANS dysfunctions, such as imbalances between the sympathetic and parasympathetic branches or impairments in the autonomic regulation of bodily functions, is crucial for preventing or slowing the progression of cardiovascular diseases.

The 3D structured light field manipulated by a digital-micromirror-device (DMD)-based digital hologram has demonstrated its superiority in fast-fabricating stereo nanostructures. However, this technique intrinsically suffers from defects of light intensity in generating modulated focal spots, which prevents from achieving high-precision micro/nanodevices. In this Letter, we have demonstrated a compensation approach based on adapting spatial voxel density for fabricating optical metalenses with ultrahigh precision.

Purpose: Nowadays, cyclin-dependent kinase 4/6 (CDK4/6) inhibitors have been approved for treating metastatic breast cancer and have achieved inspiring curative effects. But some discoveries have indicated that CDK 4/6 are not the requisite factors in some cell types because CDK2 partly compensates for the inhibition of CDK4/6. Thus, it is urgent to design CDK2/4/6 inhibitors for significantly enhancing their potency.
