Orthopedic implants need to bond firmly with surrounding bone while resisting microbes that can grow on their surfaces. Implants used after bone-cancer surgery face another challenge: limiting how many bone cancer cells remain alive on the implant surface. Researchers tested whether an implant coating could address these problems by locally delivering curcumin, a compound from turmeric, and ginger extract. This preclinical study used a titanium alloy commonly studied for load-bearing implants, coated with hydroxyapatite, a bone-like calcium phosphate. Some coatings also contained zinc oxide an... bone cancer curcumin

Colds undermine the health and well-being of millions each year, yet few effective strategies exist to prevent infection or cut recovery time. Researchers in Japan tested whether a broccoli seed extract that supplies sulforaphane glucosinolate, a precursor of the phytochemical sulforaphane, could lessen cold symptoms in people who say they catch colds easily. The trial enrolled 66 healthy Japanese adults and randomly assigned them to take either the extract (100 mg sulforaphane glucosinolate per day) or a placebo powder for eight weeks. Broccoli seed extract improved several outcomes: On av... immune system sulforaphane virus

As the global population ages, the number of people at risk for Alzheimer's disease and other forms of dementia increases. A robust and growing body of evidence indicates that lifestyle influences the risk of developing dementia. A recent study found that multivitamin/mineral supplements improve memory and slow cognitive aging in older adults – roughly equivalent to reducing cognitive aging by two years. Researchers investigated the effects of multivitamin/mineral supplementation on cognitive function in a subset of participants enrolled in the COSMOS study, a randomized, double-blind, placebo... brain alzheimer's aging micronutrients dementia

Tooth decay – a risk factor for cavities and tooth loss – often begins as white spots on the enamel, an early sign of demineralization. Strategies that promote tooth remineralization can reduce the need for invasive dental procedures. A 2022 study found that vitamin D promotes tooth remineralization, potentially reducing the risk of cavities. Researchers gave 40 healthy adults vitamin D supplements (1,000 IU) for six weeks. They collected saliva samples from the participants at the beginning of the intervention and again at the third and sixth weeks. They exposed healthy, extracted teeth to a... vitamin d inflammation dental

Spermidine is a polyamine compound that may increase health span due to its ability to induce autophagy, the process by which the body removes damaged and dysfunctional cells. In animal models, spermidine supplementation has been shown to prevent memory loss. Findings from a recent report detail the first experiment exploring the effects of spermidine supplementation on memory in older adults without dementia. Episodic memory, which records specific events, situations, and experiences, declines with age, but this loss may be impeded by certain lifestyle interventions, such as caloric restricti... brain alzheimer's autophagy dementia supplements

Type 2 diabetes is a metabolic disorder characterized by high blood sugar and insulin resistance. Long-term complications from poorly controlled type 2 diabetes include heart disease, stroke, diabetic retinopathy (and subsequent blindness), kidney failure, and diminished peripheral blood flow, which may lead to amputations. An estimated 500 million people (https://diabetes.diabetesjournals.org/content/67/Supplement_1/202-LB) worldwide are living with type 2 diabetes. A 2017 study suggests that sulforaphane may be beneficial in treating the symptoms of type 2 diabetes. Sulforaphane is an isoth... diabetes sulforaphane insulin isothiocyanates blood sugar nrf2
