    TLDR Combining ATRA with TPO-RA effectively stabilizes platelet counts in ITP patients.
    The study investigated the effectiveness of combining all-trans retinoic acid (ATRA) with thrombopoietin receptor agonists (TPO-RA) to stabilize platelet counts in idiopathic thrombocytopenic purpura (ITP) patients. Conducted at Nanfang Hospital, the study included 15 patients after excluding 2 due to severe headaches. The results showed that ATRA, administered at 20 mg daily, successfully resumed platelet response in 86.67% of cases. The treatment was generally well-tolerated, with side effects such as dry lips, hair loss, headache, and rash occurring at low rates. The findings suggest that short-term ATRA treatment is both effective and safe for managing platelet fluctuations in ITP patients on TPO-RA therapy.

      community DLQ01: A Better "Minoxidil" PGF2a synthetic analogue.

      in Research/Science  3 upvotes 9 months ago
      DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

      Painkillers like Aspirin may reduce Minoxidil's effectiveness by inhibiting the enzyme PGHS-1, which is crucial for hair growth. Using NSAIDs that inhibit COX-2 or combining Minoxidil with PGF2/E2 analogues or retinoids may enhance its efficacy.

      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.
