    TLDR Pigs can make some essential fats and don't need them all in their diet to grow and stay healthy.
    In a study with 29 5-week-old Yorkshire pigs, researchers found that pigs fed a fat-free diet for 28 days did not show significant differences in weight gain compared to those fed a normal diet with corn oil, and no skin lesions or alopecia were observed. However, the fat-free diet resulted in lower body dry matter and ether extract, and altered fatty acid concentrations, with higher palmitoleic and oleic acids and lower linoleic acid, despite synthesizing an average of 7 grams of linoleic acid. The study concluded that pigs can synthesize some linoleic acid and not all essential fatty acids are required in the diet for growth and maintenance.

      A user noticed non-itchy, non-bleeding spots on their scalp while experiencing hair loss. Replies suggest the spots are likely sunspots or liver spots and recommend seeing a dermatologist; hair loss is attributed to male pattern baldness.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      in Research/Science  64 upvotes 11 months ago
      Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.
