Transcription elongation, especially RNA polymerase II (Pol II) pause-release, is less studied than transcription initiation in regulating gene expression during meiosis. It is also unclear how transcription elongation interplays with transcription initiation. Here, we show that depletion of NKAPL, a testis-specific protein distantly related to RNA splicing factors, causes male infertility in mice by blocking the meiotic exit and downregulating haploid genes.

Introduction: Prone positioning with head rotation can influence cerebral haemodynamics, potentially affecting cerebral perfusion and oxygenation. Elderly patients with impaired brain perfusion and oxygenation are at an increased risk of developing postoperative delirium (POD). Despite this, few studies have explored whether head orientation during prone positioning contributes to POD in older adults, an aspect often overlooked by clinicians.

The increasing development of new genetically modified organisms underscores the critical need for comprehensive safety assessments, emphasizing the significance of molecular evidence such as gene integration, copy numbers, and adjacent sequences. In this study, the maize nitrate-efficient utilization gene ZmNRT1.1 A was introduced into maize variety y822 using transgenic technology, producing transgenic maize events ND4401 and ND4403 with enhanced tolerance to low nitrogen stress.

Alternative splicing (AS) contributes to transcript and protein diversity, affecting their structure and function. However, the specific transcriptional regulatory mechanisms underlying AS in the context of hepatic ischemia reperfusion (IR) injury in mice have not been extensively characterized. In this study, we investigated differentially alternatively spliced (DAS) genes and differentially expressed transcripts (DETs) in a mouse model of hepatic IR injury using the high throughput RNA sequencing (RNA-seq) analysis and replicate multivariate analysis of transcript splicing (rMATS) analysis.

The induction of adipose thermogenesis plays a critical role in maintaining body temperature and improving metabolic homeostasis to combat obesity. β3-adrenoceptor (β3-AR) is widely recognized as a canonical β-adrenergic G-protein-coupled receptor (GPCR) that plays a crucial role in mediating adipose thermogenesis in mice. Nonetheless, the limited expression of β3-AR in human adipocytes restricts its clinical application.

Plants, various biological organisms, and certain marine organisms typically provide biopolymers, like cellulose. Some things that make them unique are that they are non-toxic, biodegradable, have high specific strength and specific modulus, are easy to change the surface of, are highly hydrophilic, and are biocompatible. Significantly, nanocellulose has emerged as a prominent development in the 21st century.

Background: The calcium-sensitive receptor (CaSR) has been identified as a key factor in the formation of kidney stones. A substantial body of research has illuminated the function of CaSR in stone formation with respect to oxidative stress, epithelial injury, crystal adhesion, and stone-associated proteins. Nevertheless, as a pivotal molecule in renal calcium excretion, its pathway that contributes to stone formation by regulating calcium supersaturation remains underexplored.

Background: In China, although policies promoting physical-medical integration have received widespread national attention, the existence and manifestation of health equity promotion within these policies still require further exploration.

Methods: This study used text analysis to examine 62 policy documents on physical-medical integration issued by various Chinese governmental departments from June 2016 to June 2023, utilizing KH Coder software for qualitative analysis.

Results: The analysis revealed a strong emphasis on public health, promoting health management and disease prevention across all age groups.

Backgroud: The high cost of blinatumomab in full doses of full treatments has led to dose reduction and fewer treatment cycles for most patients in China. With current needs for cost-efficiency and resource management in health care, we retrospectively evaluated the clinical effects of short-course blinatumomab treatment for R/R Ph- B-ALL at our center.

Methods: Blinatumomab was administered with 24-h continuous intravenous infusion (9 μg/day for the first 3 days and 28 μg/day for 6-10 days).

Visit-to-visit blood pressure variability is a factor for a series of cardiovascular diseases in hypertensive patients. Hypertension is a common complication of patients with type 2 diabetes mellitus. Our research demonstrated that blood pressure variability is more important than systolic blood pressure to be associated with the occurrence of coronary artery disease and stroke.

  • - Podocyte injury is a key factor in developing diabetic nephropathy, influenced by high blood sugar, oxidative stress, and inflammation.
  • - The protein SIRPα is crucial for maintaining the health of podocytes; its deletion worsens damage while overexpression helps protect against injury in experimental models.
  • - SIRPα regulates processes involving pyruvate kinase M2 (PKM2) that lead to oxidative stress and impaired cell metabolism; a compound called shikonin can reduce this damage by blocking harmful PKM2 activity and restoring normal metabolism.
