Dopamine receptors in the brain influence itch-related scratching behavior.

Scientists created a new 3D skin model from cells of plucked hairs that works like real skin and is easier to get.

Procyanidins from grape seeds reduce nerve pain by blocking specific proteins and inflammation.

PEA reduces pain by increasing neurosteroid synthesis in the spinal cord.

Changing protein kinase levels in pituitary cells affects calcium flow and beta-endorphin release.

Hair can absorb and transfer opiates when soaked in water, with damaged hair absorbing more.

Olfactory receptors found outside the nose may offer new treatments for diseases like cancer and help in wound healing and hair growth.

Neuroactive steroids affect cocaine's rewarding effects through the ς₁ receptor.

Different soft tissue fillers can cause various skin reactions; biodegradable fillers are safer and non-biodegradable ones like silicone can lead to long-term problems.

Women with type 1 diabetes often have polycystic ovary syndrome and excess male hormones, which are frequently undiagnosed.

Stress and alcohol affect brain chemicals differently in rats, mice, and humans, influenced by genetic differences.

Selective Androgen Receptor Modulators (SARMs) are drugs that can control the effects of androgens in different tissues, potentially having fewer side effects and promising for treating various conditions.

New treatments for diabetes, central nervous system repair, and cartilage injury were found, and a way to create functional hair follicles from stem cells was developed.

Hair loss in Cronkhite-Canada syndrome may be due to an autoimmune response.

Acne can appear or persist in adulthood due to hormonal changes, external factors, or substance use, and requires appropriate treatment.

Antiyeast treatments work better for seborrheic dermatitis than steroids, and other findings include increased skin bacteria under plastic wrap, a nasal cell defect in Staphylococcus aureus carriers, quick resolution of certain skin reactions, high rubber latex allergy in spina bifida patients, and glyceryl monopentadecanoate's effectiveness for male hair loss.

Environmental factors can greatly reduce drug levels in hair.

Epimorphin helps shape and develop epithelial cells, like those in hair follicles.

Opioid use may lower PSA levels, suggesting a possible role in prostate cancer control; PSA testing is useful for detecting prostate cancer; serum triglycerides are not linked to prostate cancer risk; and higher urethral PSA levels may be associated with local hormone activity.
