Hypothyroidism is the most commonly diagnosed endocrine disorder in dogs. It produces a deficiency of thyroid hormones which impacts negatively the dog's quality of life. The objective of this study is to evaluate the possible changes in the salivary metabolic profile in dogs with hypothyroidism. For this purpose, targeted metabolomics analysis performed by LC/MS analysis was made in saliva samples from a group of dogs with hypothyroidism and a group of healthy dogs. Twenty-three metabolites showed a significant decrease between hypothyroid and healthy dogs, most of these associated with thyroid hormone synthesis, catecholamine synthesis, and tyrosine and phenylalanine metabolism. Based on the results, it can be stated that hypothyroidism produces changes in the metabolome of saliva and some of them can reflect the metabolic changes presented in the disease and could serve as a potential biomarker of this condition.

Background: Puberty has been historically considered as a time of risk and vulnerability for young people. It is associated with rapid development in the hypothalamus, which is central in the production of both stress and sex steroids. While patterns of stress reactivity are calibrated in early life, this time of rapid development may provide a means for these patterns to change.

Introduction: Mumps is a vaccine-preventable disease caused by the paramyxovirus affecting the salivary gland and may be complicated by orchitis, oophoritis, and encephalitis. This study aims to describe the epidemiology, clinical presentation, and transmission of mumps cases in the Kingdom of Bahrain between 2012 and 2022.
Methodology: A retrospective cross-sectional study was conducted using national surveillance data of confirmed mumps cases, including all age groups and both Bahraini and non-Bahraini nationals, from January 2012 to December 2022.

Background: Individuals undergo significant stress throughout pregnancy and are at high risk for depressive symptoms. Elevated stress and depressive symptoms are associated with inflammatory processes and adverse maternal-infant outcomes. However, the biological processes associated with psychosocial outcomes and the maternal immune system remain unclear.

Characterized by a cascade of profound changes in nucleus pulposus (NP) cells, extracellular matrix (ECM), and biomechanics, intervertebral disc degeneration is a common multifactorial condition that may lead to various degenerative lumbar disorders. Therapeutic strategies targeting a single factor have shown limited efficacy in treating disc degeneration, and approaches that address multiple pathological ingredients are barely reported. In this study, engineered cell membrane-encapsulated keratin nanoparticles are developed to simultaneously alleviate NP cell senescence and promote ECM remodeling.

Circadian rhythms, intrinsic 24-h cycles that drive rhythmic changes in behavior and physiology, are important for normal physiology and health. Previous work in adults has identified sex differences in circadian rhythms of melatonin, temperature, and the intrinsic period of the human circadian timing system. However, less is known about sex differences in circadian rhythms at other developmental stages.
