Importance: Patients with chronic kidney disease (CKD) are at high risk for cardiovascular disease, but their systematic underrepresentation in cardiovascular randomized clinical trials (RCTs) limits the generation of appropriate evidence to guide cardiovascular risk management (CVRM).

Objective: To evaluate the underrepresentation of patients with CKD in cardiovascular RCTs, and to highlight evidence gaps in CVRM medications in this population.

Evidence Review: A systematic search was conducted in ClinicalTrials.

Objectives: To determine whether clinical trial register (CTR) searches can accurately identify a greater number of completed randomized clinical trials (RCTs) than electronic bibliographic database (EBD) searches for systematic reviews of interventions, and to quantify the number of eligible ongoing trials.

Study Design And Setting: We performed an evaluation study and based our search for RCTs on the eligibility criteria of a systematic review that focused on the underrepresentation of people with chronic kidney disease in cardiovascular RCTs. We conducted a combined search of ClinicalTrials.

Article Synopsis
  • Weed infestations threaten global crop yields, and glyphosate is a common herbicide that targets the EPSPS enzyme, crucial for amino acid synthesis in plants.
  • Researchers used CRISPR/Cas9 gene editing to develop herbicide-resistant maize by replacing a part of the ZmEPSPS gene with a modified version, resulting in plants with triple amino acid substitutions that enhance glyphosate tolerance.
  • The edited maize showed similar agronomic performance to wild-type plants while containing higher levels of aromatic amino acids, indicating the potential for creating elite maize varieties that can withstand glyphosate without compromising yield.

Introduction: Despite growing awareness of post-coronavirus disease 2019 (COVID-19) cholangiopathy as one of the most serious long-term gastrointestinal consequences of COVID-19, the endoscopic features of this disease are still poorly characterized. This study aimed to more precisely define its endoscopic features and to outline the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of this entity.

Methods: In this observational study, 46 patients with confirmed post-COVID-19 cholangiopathy were included.

Prospectively, agroecosystems for the growth of crops provide the potential fertile, productive, and tropical environment which attracts infestation by weedy plant species that compete with the primary crop plants. Infestation by weed is a major biotic stress factor faced by pigeonpea that hampers the productivity of the crop. In the modern era with the development of chemicals the problem of weed infestation is dealt with armours called herbicides.

Article Synopsis
  • Maize, a critical global crop, uses complex gene regulation mechanisms to adapt to drought stress, with the HKI 335 inbred line showing notable resilience.
  • Reactive oxygen species (ROS) produced during drought can cause cellular damage, but the enzyme superoxide dismutase (SOD) plays a key role in defending against this damage.
  • Detailed analysis of the HKI 335 SOD2 protein revealed its similarity to a known thermostable SOD, with favorable structural properties and a low instability index, indicating its potential effectiveness in stress tolerance.

Article Synopsis
  • * Different isoforms of PAPs are found in various parts of the plant Setaria italica, and their expression increases when the plant is low on phosphorus, helping to improve phosphorus availability.
  • * Researchers isolated the SiPAP18 gene and created a protein model based on a similar structure from kidney beans, highlighting five important conserved features and seven metal-binding amino acids that are crucial for phosphorus enhancement under nutrient-poor conditions.

Only a select few L1 loci in the human genome are expressed in any given cell line or organ, likely to minimize damage done to the genome. The epigenetic features and requirements of expressed L1 loci are currently unknown. Using human cells and comprehensive epigenetic analysis of individual expressed and unexpressed L1 loci, we determined that endogenous L1 transcription depends on a combination of epigenetic factors, including open chromatin, activating histone modifications, and hypomethylation at the L1 promoter.

Stacking Glutathione-Ascorbate pathway genes (PgSOD, PgAPX, PgGR, PgDHAR and PgMDHAR) under stress inducible promoter RD29A imparts significant tolerance to drought and salinity stress in Solanum lycopersicum. Although the exposure of plants to different environmental stresses results in overproduction of reactive oxygen species (ROS), many plants have developed some unique systems to alleviate the ROS production and mitigate its deleterious effect. One of the key pathways that gets activated in plants is ascorbate glutathione (AsA-GSH) pathway.

Expression of L1 mRNA, the first step in the L1 copy-and-paste amplification cycle, is a prerequisite for L1-associated genomic instability. We used a reported stringent bioinformatics method to parse L1 mRNA transcripts and measure the level of L1 mRNA expressed in mouse and rat organs at a locus-specific resolution. This analysis determined that mRNA expression of L1 loci in rodents exhibits striking organ specificity with less than 0.

Article Synopsis
  • Alu elements are common in the human genome and play a significant role in causing genetic instability, particularly during DNA double-stranded breaks due to their high copy number and characteristics that affect recombination.
  • Using a reporter-gene assay, the study reveals that mismatches between Alu elements can lead to two main outcomes: either nonallelic homologous recombination (HR) or DNA breaks that can cause deletions through alternative repair processes.
  • The formation of these intermediates is dependent on RAD52, and the presence of defects in DNA repair genes like ERCC1 and MSH2 influences the types of deletions associated with Alu elements, which may contribute to different cancer types.

Genome editing (GE) technology has emerged as a multifaceted strategy that instantaneously popularised the mechanism to modify the genetic constitution of an organism. The clustered regularly interspaced short palindromic repeat (CRISPR) and CRISPR-associated (Cas) protein-based genome editing (CRISPR/Cas) approach has huge potential for efficacious editing of genomes of numerous organisms. This framework has demonstrated to be more economical in contrast to mega-nucleases, zinc-finger nucleases (ZFNs), and transcription activator-like effector nucleases (TALENs) for its flexibility, versatility, and potency.
