Welfare assessment of stabled horses in five equestrian disciplines.

In Serbia, at present, there is very little information about the welfare of horses. The aim of this study was to identify the main welfare issues likely to be encountered in five different categories of horses (Western riding horses, riding school horses, leisure horses, jumping horses, and endurance horses) kept in stabled housing systems. A total of 50 horses were evaluated using the Animal Welfare Indicator (AWIN) welfare assessment protocol for horses.

An investigation into how ownership factors influence the lifestyle and health management of rabbits.

Gaps in skills, knowledge, and experience can hinder pet owners' ability to provide proper care and good animal welfare. This study aimed to examine how past and current experiences, reasons for acquiring rabbits, and methods of knowledge acquisition impact the lifestyle and health of pet rabbits in households. Among 306 rabbit owners surveyed, 25% had previous experience with rabbits, and 54% had owned rabbits for over 3 years.

Transcriptional Profiles of Mitochondrial Dynamics Markers Are Disturbed in Adrenal Glands of Stressed Adult Male Rats.

Mitochondrial dynamics plays a significant role in shaping the mitochondrial network and maintaining mitochondrial function. Imbalanced mitochondrial dynamics can cause mitochondrial dysfunction leading to a wide range of diseases/disorders. The aim of this study was to investigate the expression of mitochondrial dynamics markers and regulatory molecules in whole adrenal glands, cortices, and medullae obtained from adult male rats exposed to acute and repeated psychophysical stress, the most common stress in human society.

The prevalence and genotype of 21-hydroxylase deficiency in the Croatian Romani population.

Objective: Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency (21-OHD) is a rare autosomal recessive disorder caused by pathological variants in the gene. After a high prevalence of classic 21-OHD CAH in the Romani population was reported in the Republic of North Macedonia, we decided to estimate the prevalence of 21-OHD in Croatia and, if high, assess the possible causes and estimate the frequency of particular variants.

Design: Cross-sectional study.

A Historical Twist on Long-Range Wireless: Building a 103 km Multi-Hop Network Replicating Claude Chappe's Telegraph.

In 1794, French Engineer Claude Chappe coordinated the deployment of a network of dozens of optical semaphores. These formed "strings" that were hundreds of kilometers long, allowing for nationwide telegraphy. The Chappe telegraph inspired future developments of long-range telecommunications using electrical telegraphs and, later, digital telecommunication.
