We aimed to investigate preventive effects of All-trans retinoic acid (ATRA) on a lipopolysaccharide (LPS)-induced aged neuroinflammation model. We analyzed behavior, systemic nitric oxide (NO) production, cerebral NO synthase (NOS2) and β-amyloid (Aβ) 1-42 expression and tissue integrity in the neuroinflammation model pretreated with ATRA (150μg/ml/rat/day) for 30days. Our results showed that LPS treatment (500μg/kg/day) for 7days disturbed memory, enhanced systemic NO production, NOS2 and Aβ 1-42 cerebral expression and generated an Alzheimer's disease (AD)-like neuronal degeneration. Interestingly, ATRA pretreatment prevented the LPS-induced deleterious effects. ATRA could be a potent preventive approach in AD.

Acute promyelocytic leukaemia (APL) is a highly lethal haematological malignancy. It is rare in pregnancy and may be fatal if not managed promptly and appropriately. A woman in her 20s presented with high-grade fever at 16 weeks of her third pregnancy.

The limited availability of corneal tissue grafts poses significant challenges in the treatment of corneal blindness. Novel treatment utilizes stem cell grafts transplanted from the healthy side of the cornea to the damaged side. However, this procedure is only possible for those who have one-sided corneal blindness.

Aims: Acute promyelocytic leukemia (APL) progresses quickly and often leads to early hemorrhagic death. Treatment with all-trans retinoic acid (ATRA) promotes differentiation of APL cells and clinical remission, making APL a potentially curable malignancy. Understanding how ATRA works may lead to new treatments for other types of leukemia.

Currently, it is unclear which signals mediate the effects of light on myopia. All- retinoic acid (atRA) and dopamine (DA) oppositely influence experimental myopia and may be involved in the retino-scleral signaling cascade underlying myopic eye growth.
