Posttraumatic stress disorder (PTSD) is a serious mental health condition that affects some individuals who have witnessed or experienced a life-threatening or traumatic event. An enhanced or exaggerated acoustic startle response (ASR), reflecting heightened sensitivity to unexpected, loud sound, is a hallmark symptom of PTSD. Antidepressant medications, such as sertraline, are first-line pharmacotherapeutic agents in the treatment of PTSD, but concerns about potential side effects or taking synthetic drugs prompt discovery of naturalistic therapeutic agents...

Firefighters and military personnel are exposed to a variety of stressors. The combination of mental and physical stress (i.e., dual stress challenges [DSCs]) results in significant oxidative stress (OS), which may contribute to cardiometabolic dysfunction. Curcumin (CUR) is an exogenous antioxidant that may attenuate such OS. Fourteen trained men participated in a randomized, cross-over design to investigate the impact of CUR on markers of OS resulting from DSC. CUR or placebo was ingested three days prior to, and the morning of, testing...

Karma Pearce, Kelton Tremellen
Previous observational studies have suggested that β-cryptoxanthin, a micronutrient present in yellow and orange fruit and vegetables, may help delay the onset of menopause. Given the widespread social trend of delaying pregnancy, the possibility that β-cryptoxanthin supplementation may delay age-related loss of fertility and onset of menopause is of significant interest. In a parallel study, either saline or β-cryptoxanthin (5 µg/kg rat/day) was delivered to Wistar albino rats via an osmotic pump from 4 to 7 months of age...

Radiation protection research receives intense focus due to its significant impact on human health. The present study was undertaken to investigate the protective effect of pretreatment with tomato seed oil (TSO) against gamma radiation-induced damage in rats. Male Wistar rats were divided into four groups: (1) untreated control; (2) TSO-supplemented; (3) gamma-irradiated; (4) TSO-pretreated and gamma-irradiated. Acute exposure of animals to a single gamma radiation dose (6 Gy) induced oxidative stress in major body organs, altered serum lipid homeostasis, significantly increased serum testosterone and sorbitol dehydrogenase levels, and elicited a systemic inflammation as manifested by the induction of serum vascular cell adhesion molecule-1...

REVIEW
Stephen Adeniyi Adefegha
Functional foods describe the importance of foods in promoting health and preventing diseases aside their primary role of providing the body with the required amount of essential nutrients such as proteins, carbohydrates, vitamins, fats, and oils needed for its healthy survival. This review explains the interaction of functional food bioactive compounds including polyphenols (phenolic acids [hydroxybenzoic acids and hydroxycinnamic acids], flavonoids [flavonols, flavones, flavanols, flavanones, isoflavones, proanthocyanidins], stilbenes, and lignans), terpenoids, carotenoids, alkaloids, omega-3 and polyunsaturated fatty acids, among others with critical enzymes (α- amylase, α- glucosidase, angiotensin-I converting enzyme [ACE], acetylcholinesterase [AChE], and arginase) linked to some degenerative diseases (type-2 diabetes, cardiovascular diseases [hypertension], neurodegenerative diseases [Alzheimer's disease] and erectile dysfunction)...
