Heavy metal(loid)s are a group of elements present commonly in the environment, including Cr, Ni, Cu, Zn, Cd, Hg, Pb, and As elements, among others. While these elements could have their origins in natural sources, anthropogenic activities, such as mining, agriculture, industry, etc., are also responsible for enhancing the concentration of these elements in the ecosystems up to undesirable levels. A few of these metal(loid)s serve as necessary micronutrients for life, while the others are extremely harmful and migh [...]

Cerebral Palsy (CP) is the most frequent cause of childhood disability. CP occurs in 1 out of every 345 children in the United States. CP is primarily a motor disease that is the result of an insult to the brain that occurs during the prenatal or early postnatal period when the brain is still developing. CP is not a single disease but a physical description of motor impairments that originate from multiple etiologies. This article briefly discusses the etiologies, classification and management of the neurologic med [...]

The dominant narrative around dementia argues that progression cannot be halted or reversed. However, evidence on multimodal non-pharmacological treatments formulated around a ‘personalised medicine’ approach challenges this view. This paper reviews the current evidence for dementia prevention utilising such treatments and explains the logic of applying personalised medicine. The functional medicine treatment approach to ‘root cause’ analysis is presented as currently practiced with patients experiencing cognitive [...]

Obesity has historically been thought to simply be related to an imbalance between energy intake and expenditure. Weight loss recommendations have traditionally focused on reducing energy intake, maintaining either a high-carbohydrate low-fat diet or vice versa, and increasing physical activity typically through low to moderate intensity exercise. More recently, genetic, physiological, and behavioral factors have also been found to play a significant role in the etiology of obesity. For this reason, the prevention [...]

Bone tissue engineering (BTE) as a modern and more effective treatment for bone defects has recently received lots of attention. One of the pivotal parts of BTE is the “scaffold”, which functions as an indwelling carrier of cells and additives, as well as, providing a foundation for cell growth and eventually forming new, native-like bone. Up to now, many methods and materials have been employed to manufacture bone scaffolds. This review focuses on providing both basic knowledge of BTE as well as possible methods o [...]

Feline cancers have not been studied as extensively as canine cancers, though they may offer similar advantages, with cats being immunocompetent animals subject to similar conditions as their human counterparts. The most common feline cancers include lymphoma, squamous cell carcinoma, sarcoma, and mammary tumors, though mast cell tumors were also investigated in this review. As the pathogenesis of many feline cancers remains unclear, this study seeks to elucidate some molecular mechanisms behind feline cancers. Fel [...]

In the United States (US), menopause occurs at an average age of 52. Menopausal symptoms tend to be maximal during the few years before and the year after menopause (during perimenopause), except for symptomatic vulvovaginal atrophy, which may worsen over time. Up to 20% of bone density loss occurs during the first 5 years after menopause, followed by an age-related bone loss rate similar to that in men. Menopause should be considered confirmed if an age-appropriate woman who is not pregnant has not had a menstrual [...]

During February 2022 major riverine flooding occurred in an area which has the fastest population growth in Australia. This extended from the Mary River in Southeast Queensland (SEQ) to the Clarence River in Northeast NSW (NENSW). Two centres within this area were devastated by floods unprecedented in living memory. One was the Brisbane Metropolitan area where all-time record daily rainfall in the suburbs flooded creeks. This creek flooding was much worse than that caused by the Brisbane River itself where Wivenhoe [...]
