This study concluded that newborn screening for biotinidase deficiency effectively identified cases and likely prevented irreversible complications from the disorder in some infants.

This study analyzed soil, water, and carrot samples in Vietnam, and found that organic farming can reduce heavy metal levels in carrots compared to conventional methods, potentially improving their nutritional safety.

In this study, the average force required to pluck hair was significantly lower in malnourished adults, especially those with kwashiorkor, compared to well-nourished individuals.

Shampooing can affect the loss of minerals like calcium and iron from hair.

This study observed telogenic defluvium and dystrophic hair loss in patients with nutritional deficits, with reversible damage when diet improves and stress is alleviated.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

This study developed a high-throughput method that identifies bioactive chemicals influencing DHT production in prostate cancer cells, with potential nutraceutical candidates including fucoxanthin, phenethyl caffeate, and Curcuma longa L. extract.

This review discusses advancements in using dissolving microneedle systems for transdermal delivery of traditional Chinese medicine, highlighting potential benefits for simplifying application, enhancing safety, and increasing efficacy, and underscores its possible impact on modernizing traditional medicine practices.

This study found that senior dogs fed amino acid-complexed and lysine-glutamic acid-complexed trace minerals had longer, faster-growing hair and increased activity compared to those fed inorganic trace minerals.

This study reported that mice with more diverse gut microbiota showed higher hair levels of certain hormones and 1-AG compared to those with less diverse microbiota, though plasma differences were more complex and varied by stress and sex.

This study found that a machine-learning-driven strategy helped develop microneedles with high hardness and rapid dissolution, effectively promoting hair regrowth in androgenetic alopecia mice by activating the Wnt/β-catenin pathway, surpassing minoxidil's effects without biosafety risks.

This case report highlights that a restrictive rice milk diet in a young child led to kwashiorkor with severe malnutrition, skin changes, and developmental regression, which improved with a protein-rich therapeutic diet.

This study found that lead accumulated in the hair shafts of individuals exposed to mining environments, while iron, copper, and zinc levels remained stable, highlighting the significance of SRXRF micro-analysis for environmental health research.

This review discusses how changes in hair and skin may indicate underlying vitamin deficiencies and emphasizes the need to identify populations at risk for these deficiencies; it reports no new results.

This study observed that low levels of calcium and magnesium in blood serum were associated with health issues like hair loss and anxiety among participants from urban and rural Pakistan.

This study validated an HPLC-UV method to detect minoxidil in cosmetic products and found that 2 out of 9 analyzed products contained minoxidil, despite international regulations banning its inclusion due to potential systemic absorption.

In this study, more than half of elderly residents in geriatric homes were found to be overweight but did not regularly take vitamins and minerals.

This study reports that an electrochemical biosensor using a gold and palladium-modified electrode effectively detects levodopa and uric acid in various samples, offering improved performance over previous electrodes.

This study identified new oxidative derivatives of finasteride, including a newly discovered metabolite, by using the fungus Macrophomina phaseolina.

This study found that spraying melon plants with 0.1 mg·L–1 molybdenum significantly improved growth, photosynthetic characteristics, carbohydrate metabolism, and fruit quality under high-temperature stress, boosting fruit weight by 27.9% and yield per plant by 20.1% compared to untreated controls.

This study assessed nutritional status in residents of geriatric homes in Al-Furat Al-Awusat, finding that the majority were overweight and lacked routine vitamin and mineral intake.

In this study, zinc deficiency, iron depletion, and thyroid abnormalities were commonly observed in female pattern hair loss patients, suggesting the benefit of testing for these conditions.

This ex vivo study found that hair follicles in female pattern hair loss exhibited nutrient insufficiency and dormant metabolism, but maintained nutrient uptake capability, suggesting potential benefits of nutritional supplementation as an adjunct therapy.

This study reports that hair analysis could potentially monitor metformin use in diabetic patients, suggesting a possible correlation between daily dose and concentration in dark hair but not in light hair.

This study's simulations revealed the complex "onion-like" organization of a lipid nanoemulsion droplet containing vitamins A and E for skin delivery, showing distinct concentration patterns of these vitamins within different layers of the nanodroplet.

This study found that 83% of community participants use cosmetic nutritional supplements, with awareness of their appropriate use suggested to be increasing, as 73% took them after lab tests and 58% followed medical prescriptions.

This study found that a more liberal intake of restricted amino acids in patients with methylmalonic acidemia resulted in improved growth and fewer illness episodes.

This case report describes a 47-year-old male with rare total melanonychia linked to vitamin B12 deficiency, whose nail discoloration and constitutional symptoms improved following vitamin B12 supplementation.

This study observed a decrease in iodine, lithium, and lead concentrations in hair samples from Venezuelan subjects over 20 years, with regional variations noted for selenium, uranium, and mercury.

This study found distinct hair metal profiles in Parkinson's disease patients, with lower iron and copper, higher manganese and arsenic, and explored their link to gut dysfunction and microbiota dysbiosis, suggesting hair metal analysis as a promising diagnostic tool.
