The saccus vasculosus of the neotropical cichlid fish Cichlasoma dimerus: characterization, developmental studies and its response to photoperiod.

The saccus vasculosus is an organ present in gnathostome fishes, located ventral to the hypothalamus and posterior to the pituitary gland, whose structure is highly variable among species. In some fishes, this organ is well-developed; however, its physiological function is still under debate. Recently, it has been proposed that this organ is a seasonal regulator of reproduction.

Long Term Remission of Capillary Leak Syndrome Associated with Monoclonal Gammopathy with Progression to Multiple Myeloma After Autologous Stem Cell Transplantation: a Case Report and Review of the Literature.

Background: Clarkson's disease is a very rare entity characterised by acute episodes of systemic oedema and severe hypotension associated with paraproteinaemia. Its classical treatment relies on methylxanthine combined with terbutaline. Although this prophylactic therapy reduces the mortality rate, relapses are frequent.

Integrating morphology and physiology of the key endocrine organ during tadpole development: The interrenal gland.

Indirect development is widespread in anurans and is considered an ancestral condition. The metamorphosis of larvae into juveniles involves highly coordinated morphological, physiological, biochemical, and behavioral changes, promoted by the thyroid hormone and interrenal corticosteroids. Stress response to environmental changes is also mediated by corticosteroids, affecting the timing and rate of metamorphosis and leading to great developmental plasticity in tadpoles.

Aberrant RET expression affects normal mammary gland post-lactation transition, enhancing cancer potential.

RET is a receptor tyrosine kinase with oncogenic potential in the mammary epithelium. Several receptors with oncogenic activity in the breast are known to participate in specific developmental stages. We found that RET is differentially expressed during mouse mammary gland development: RET is present in lactation and its expression dramatically decreases in involution, the period during which the lactating gland returns to a quiescent state after weaning.

Dasatinib and FLAG-IDA Is an Effective Therapy for Initial Myeloid Blast Crisis but Involves a High Risk of Opportunistic Infections.

Blast crisis (BC) continues to be the major challenge in the treatment of chronic myeloid leukemia. Best results have been observed in a few patients who were successfully transplanted after returning to chronic phase. Recent studies focus on the combination of chemotherapy with imatinib, but results remain unsatisfactory.
