Genotype-by-Environment Effects of Cis-Variations in the Atgl Promoter Mediate the Divergent Pattern of Phenotypic Plasticity for Temperature Adaptation in Two Congeneric Oyster Species.

Phenotypic plasticity plays an essential role in adaptive evolution. However, the molecular mechanisms of how genotype-by-environment interaction (G × E) effects shape phenotypic plasticity in marine organisms remain poorly understood. The crucial temperature-responsive trait triacylglycerol (TAG) content and its major gene adipose triglyceride lipase (Atgl) expression have divergent plastic patterns in two congeneric oyster species (Crassostrea gigas and Crassostrea angulata) to adapt to relative-cold/northern and relative-warm/southern habitats, respectively.

Emissions of HFC-23 do not reflect commitments made under the Kigali Amendment.

HFC-23 (trifluoromethane) is a potent greenhouse gas released to the atmosphere primarily as a by-product of HCFC-22 (chlorodifluoromethane) synthesis. Since 2020, the Kigali Amendment to the Montreal Protocol has required Parties to destroy their HFC-23 emissions to the extent possible. Here, we present updated HFC-23 emissions estimated from atmospheric observations.

Novel flame retardants (NFRs) in e-waste: Environmental burdens, health implications, and recommendations for safety assessment and sustainable management.

Novel flame retardants (NFRs) have emerged as chemicals of environmental health concern due to their widespread use as an alternative to polybrominated diphenyl ethers (PBDE) in electrical and electronic devices.

Unveiling the Synergy of Serum Lipoprotein-Associated Phospholipase A2 and PLA2G7 Gene Polymorphism (rs1805017) as Key Determinants of Coronary Artery Disease Risk and Severity: Implications for Early Intervention.

Background Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a key enzyme selectively expressed in unstable, rupture-prone atherosclerotic plaques. Previous research has established a strong link between the gene and the development of coronary artery disease (CAD). While traditional risk factors like cholesterol levels and blood pressure are valuable, there remains a need for more specific biomarkers to identify individuals at heightened risk of atherosclerosis before the onset of clinical symptoms.

Optimization of Subscapularis Tendon Repair in Stemless Shoulder Arthroplasty Using a Resorbable Pressure-Dissipating Onlay Suture Disk Implant.

Successful subscapularis repair in stemless shoulder arthroplasty is crucial to reduce complications and improve postoperative function. As stemless shoulder arthroplasty continues to grow in popularity, several subscapularis tendon repair techniques are being developed, with a current trend toward knotless devices and double-row anchor-based constructs. In this article, we present our technique for repair of a subscapularis tendon peel using a suture-capture construct that aids in compression of the tendon onto its footprint and then gradually releases the tension as the capture resorbs and tendon healing occurs.

Controlling the Hierarchical Assembly of DNA-Based Hexagonal Microstructures.

This paper discusses the controlled morphology of hierarchical liquid crystalline DNA assemblies. Through a process of heating and slow cooling, double-stranded DNAs (dsDNAs) having 23 complementary bases and two base overhangs (a pair of 25mer oligonucleotides) spontaneously assemble into micro-sized hexagonal platelets in a solution containing poly(ethylene glycol) (PEG) and salt. Remarkably, the addition of a shorter dsDNA with AA/TT overhangs (a pair of 18mer oligonucleotides) to a PEG-salt solution of 25mer DNA with AA/TT overhangs results in the formation of molecular tubes, each with a central blockage.
