20-HETE/GPR75 pairing modulates the expression and transcriptional activity of the androgen receptor in androgen-sensitive prostate cancer cells.

The androgen receptor (AR) and AR-driven genes are crucial in normal and neoplastic prostate tissue. Previous results showed a link between 20-hydroxyeicosatetraenoic acid (20-HETE) production and AR-driven prostate cancer (PCa) progression. This study aims to describe the contribution of GPR75, 20-HETE membrane receptor, in 20-HETE-mediated expression and transcriptional activity of AR in PCa.

[Assessment of ovarian reserve during gender affirmation hormone therapy in trans men].

Trans man is a biological female person with male gender identity, who can choose to receive a genderaffirming hormone treatment with testosterone. So far, the effects of this treatment on reproduction are unclear. Anti-müllerian hormone levels were evaluated in trans men during short-term testosterone treatment.

Type-I Cryoglobulinaemia Associated to Monoclonal Gammapathy of Undetermined Significance.

Cryoglobulins are immunoglobulins that undergo reversible precipitation at cold temperatures. Monoclonal type-I cryoglobulinaemia is the least frequent and is associated to hematological diseases such as multiple myeloma, Waldenström's macroglobulinaemia, chronic lymphocytic leukaemia and lymphoma. We describe the case of a 60-year-old female patient, who suffered from burning pain in her feet for ten months before her admission.

[Short-term safety profile of cross-hormonal therapy in trans-male subjects].

A trans-male (TM) is a biologically female person with male gender identity who wishes to acquire male sexual characteristics and fulfil a male social role. To achieve that purpose, both cross-hormonal therapy (CHT) and surgical phalloplasty can be used. We evaluated the short term (12 months) safety profile of CHT using different forms of testosterone available for prescription in Argentina.

[Chronic inflammatory demyelinating polyneuropathy in a diabetic patient with syphilis].

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a disorder characterized by motor symptoms such as weakness in both proximal and distal muscles with globally diminished or absent reflexes. Insulin neuritis is referred as an acute pain in the extremities, due to the damage of peripheral nerves affecting mainly small fibers, in diabetic patients treated with insulin who achieved rapid glycemic control. Pain is unusual in classic CIDP.

Role of 20-Hydroxyeicosatetraenoic Acid (20-HETE) in Androgen-Mediated Cell Viability in Prostate Cancer Cells.

20-Hydroxyeicosatetraenoic acid (20-HETE) is generated intracellularly through the ω-hydroxylation of arachidonic acid by the cytochrome P450 (in humans, CYP4A11 and CYP4F2). 20-HETE induces mitogenic responses in different cancer cells. The aim of this study was to analyze how 20-HETE impacts cell survival, proliferation, and apoptosis in prostate cancer cells.

[Body weight increase and quality of semen: a controversial association].

Background: Infertility is a public health disorder affecting 10% of the population worldwide. Research on the impact of body mass index (BMI) on male fertility is very limited as compared to the multiple studies evaluating the impact of overweight in women's fertility. Although 25%-30% of the cases of couples consulting for infertility are attributable to male factors, studies evaluating the association between semen parameters and BMI are controversial.
