Technologies for equine welfare and performance monitoring under field conditions – Where do we stand?

open access: yesEquine Veterinary Journal, EarlyView.
Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Quantitative assessment of gait alterations and variability in sulky‐driven Standardbred trotters after a standardised exercise test

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Assessment of equine metabolic and locomotory responses to quantified levels of physical exercise is needed to support the creation of tailored protocols for optimal training adaptation. The locomotory response to exercise in horses is not fully understood.

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

open access: yesThe FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Tolerance of Egg and Yolk‐Sac Larval Yellowfin Sole (Limanda aspera) to Ocean Warming and Acidification

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Yellowfin sole (Limanda aspera) support the largest flatfish fishery in the world and contribute substantially to the eastern Bering Sea (EBS) flatfish catch. The EBS has been warming and acidifying, trends that are expected to intensify into the future.

Dentine Regeneration With Calcium Strontium Silicate: In Vitro Odontogenic Differentiation, Antimicrobial Activity, Immunomodulation and In Vivo Pulpotomy in Rat Molars

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim This study examined the in vitro and in vivo performance of calcium strontium silicate (CSR) as a novel biomaterial for vital pulp therapy (VPT), assessing its odontogenic differentiation, antibacterial activity, immunomodulation, inflammatory response and dentine regeneration potential compared to calcium silicate (CS) and Mineral ...
