Xylitol is one of the most extensively studied sugar alcohols for oral health. Unlike regular sugar, it cannot be effectively metabolized by the primary bacteria responsible for dental caries (cavities), making it a valuable adjunct to good oral hygiene. What is Xylitol? Xylitol is a naturally occurring sugar alcohol found in small amounts in fruits, vegetables, and hardwood trees such as birch. It has approximately the same sweetness as sucrose but contains about 40% fewer calories . Unlike sugar, xylitol has a very low glycemic index and does not promote acid production by oral bacteria. How Xylitol Prevents Dental Caries 1. Reduces cavity-causing bacteria The major bacterium associated with dental caries is Streptococcus mutans. Normally: Sugar → bacteria ferment it Acid is produced Tooth enamel demineralizes Cavities develop With xylitol: Bacteria take up xylitol They cannot efficiently metabolize it Energy is wasted ...

Microplastics (particles <5 mm) and nanoplastics (typically <1 μm) are increasingly recognized as potential disruptors of mitochondrial function. Mitochondria produce over 90% of the body's ATP (energy), regulate oxidative stress, control apoptosis (programmed cell death), and influence immune responses. Experimental research suggests that microplastics can impair many of these functions, although evidence in humans remains limited. How Microplastics Reach Mitochondria Humans are exposed through: Food and drinking water Seafood Airborne dust Plastic food packaging Synthetic textiles Personal care products While larger microplastics are less likely to enter cells, nanoplastics can cross biological barriers, enter cells through endocytosis, and accumulate in organelles, including mitochondria in laboratory models. Mechanisms of Mitochondrial Damage 1. Excessive Reactive Oxygen Species (ROS) One of the earliest effects observed is increased mitochondri...

A comprehensive, peer-reviewed synthesis of preclinical and clinical evidence for H₂ therapy across 20 disease categories — 2026 Update Published: June 2026 Last Reviewed: June 2026   2026 Update References: 160+ citations Category: Integrative Medicine | Antioxidant Therapy Reading Time: ~18 min Peer-Reviewed Format Abstract Molecular hydrogen (H₂) has emerged over the past two decades as a uniquely versatile therapeutic agent, distinguished by its ability to selectively scavenge cytotoxic reactive oxygen species (ROS) while crossing all biological barriers, including the blood-brain barrier. Since the landmark 2007 Nature Medicine publication, more than 5,000 papers and over 100 registered clinical trials have examined H₂ across conditions spanning neurodegeneration, cancer, cardiovascular disease, metabolic syndrome, inflammatory disorders, and respiratory illness. This updated review synth...

Gynaecology or gynecology is the medical practice dealing with the health of the female reproductive systems (vagina, uterus and ovaries), breasts and pregnancy related management. Literally, outside medicine, it means "the science of women". Almost all modern gynaecologists are also obstetricians and therefore the term obstetricians & gynecologists or O&G or OBGYN in short. In many areas, the specialties of gynaecology and obstetrics overlap. Finding a trusted medical specialist is one of the most personal and critical healthcare decisions a woman can make. Whether you are navigating your first pregnancy, seeking treatment for reproductive health concerns, or exploring fertility options like IVF, choosing the right doctor matters deeply. In this completely updated guide, we highlight the leading obstetricians and gynecologists (O&G or OBGYN) in Johor . From major government referral institutions to premiu...
