The first complete hand-rearing of two neonatal finless porpoises.

PLoS One

January 2025

Laboratory of Veterinary Biochemistry, School of Veterinary Medicine, Rakuno Gakuen University, Ebetsu, Hokkaido, Japan.

Hand-rearing of marine mammals is an essential technique for the husbandry of orphans in captivity or the wild, especially endangered cetacean species. The purpose of the present study was to establish a method for successful hand-rearing and evaluate the nutritional state of neonatal finless porpoises. Two neonate finless porpoises maternally neglected at 5 days of age (Day 5) (neonate A, animal A) and Day 4 (neonate B, animal B) were hand reared.

Oxygen Activation Biocatalytic Precipitation Strategy Based on a Bimetallic Single-Atom Catalyst for Photoelectrochemical Biosensing.

Anal Chem

January 2025

Key Laboratory of Optic-Electric Sensing and Analytical Chemistry for Life Science, MOE; College of Chemistry and Molecular Engineering, Qingdao University of Science and Technology, Qingdao 266042, PR China.

Article Synopsis
  • The traditional biocatalytic precipitation (BCP) method has limitations due to HO's tendency to self-decompose, affecting its effectiveness in quantitative analysis.
  • Researchers discovered that a bimetallic single-atom catalyst (Co/Zn-N-C SAC) can activate dissolved oxygen to create reactive oxygen species, leading to improved detection methods.
  • The development of a new oxygen-activated photoelectrochemical (PEC) biosensor for chloramphenicol (CAP) detection demonstrates enhanced stability and accuracy by using Co/Zn-N-C SAC and cesium platinum bromide nanocrystals (CsPtBr NCs) without needing external reactants.

Boriranes, highly strained three-membered cyclic organoboron heterocycles, have emerged as potential synthons for the synthesis of many organoboron species. However, the synthesis of boriranes with tricoordinate, sp-hybridised boron and tetracoordinate, sp-hybridised carbon atoms is very challenging owing to their high Lewis acidity. Herein we describe the isolation of base-free triaminoboriranes from the room-temperature reaction of diaminoalkynes with an aminodistannylborane.

The amino acid permease contributes to tomato growth and salt tolerance by mediating branched-chain amino acid transport.

Hortic Res

January 2025

National Key Laboratory for Tropical Crop Breeding, School of Breeding and Multiplication Sanya Institute of Breeding and Multiplication, Hainan University, Sanya 572025, China.

Branched-chain amino acids (BCAAs) are essential amino acids in tomato () required for protein synthesis, which also modulate growth and abiotic stress responses. To date, little is known about their uptake and transport in tomato especially under abiotic stress. Here, the tomato () gene was identified as an amino acid transporter that restored mutant yeast cell growth on media with a variety of amino acids, including BCAAs.

Cotton is essential for the global textile industry however, climate change, especially extreme temperatures, threatens sustainable cotton production. This research aims to identify breeding strategies to improve heat tolerance and utilize stress-resistant traits in cotton cultivars. This study investigated heat tolerance for 50 cotton genotypes at the seedling stage by examining various traits at three temperatures (32 °C, 45 °C and 48 °C) in a randomized plot experiment.
