Understanding how different body systems interact can improve how we prevent or treat frailty in aging.

MFN2 mutations cause mitochondrial problems, leading to more upper body fat and lower leptin levels.

Decursin shows promise for treating cancer, neuroprotection, inflammation, and hair loss.

Soy hull supplement does not affect sheep and lamb growth or reproductive performance compared to corn-based supplements.

MFN2 mutations cause mitochondrial problems, unusual fat distribution, and low leptin despite high body fat.

Cobalt is important for health but too much or too little can cause health problems, and its environmental buildup is a concern.

Finasteride modifies 5-alpha-reductases through a two-step process, affecting inhibitor potency and possibly causing side effects.

The document concludes that better biomarkers are needed to detect long-term oral testosterone use in athletes.

Scientists created a colored thread-like material containing a common hair loss treatment, which slowly releases the treatment over time, potentially offering an effective, neat, and visually appealing solution for hair loss.

Silver oxide nanoparticles help detect small molecules effectively.

Vitamin B can prevent hair from turning gray in rats.

Different drugs can treat high male hormone levels in women, but they have various effects and some may harm a fetus.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

Hair color and length affect metabolite profiles in hair, so they should be considered in hair analysis.

Hair analysis is better than urine and blood for detecting past drug use.

DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.

Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

Pyrene excimer nucleic acid probes are promising for detecting biomolecules accurately with potential for biological research and drug screening.

Finasteride irreversibly affects human steroid 5α-reductase 2, providing insight into its catalytic mechanism and disease-related mutations.

The research explains how a human enzyme binds and processes its substrate, which could relate to its role in biological functions and hair loss.

LY320236 is a strong blocker of two enzymes that change testosterone into dihydrotestosterone and might help treat conditions related to male hormones.

New signs like changes in blood markers, physical symptoms, and behavioral shifts may help detect hidden steroid use in athletes.

Rat skin takes up and processes testosterone differently than other organs, with testosterone being more important for the skin than its metabolite 5α-DHT.

Finasteride safely treats enlarged prostate and male-pattern baldness.

Taking Saw palmetto and Pygeum africana can change the levels of certain steroids in urine, which could cause confusion in doping tests.
