Introduction: Vital dyes lymphography during laparoscopic varicocelectomy (LV) has been suggested to allow for lymphatic mapping thereby allowing for lymphatic sparing (LS) and subsequent reduction of hydrocele formation. Intratesticular injection of the dye seems to achieve the best lymphatic visualization, however, the potential toxicity of some agents, is a cause of concern for the risk of testicular pathological changes. We report our experience with LV, to test the hypothesis that Intraoperative lymphography with methylene blue (BL), is safe and reduces the rate of post-operative hydrocelectomy.

- Several studies have explored the neural correlates of trans individuals, revealing inconsistent findings. This particular study focused on comparing functional connectivity, cognitive profiles, and hormone levels among trans men with gender dysphoria, cisgender men, and cisgender women.
- A total of 42 participants underwent resting state fMRI and hormonal analysis, revealing that trans men showed reduced functional connectivity in various brain regions and performed worse in certain cognitive tasks compared to cisgender men, but similarly to cisgender women.
- The study found significant correlations between testosterone and specific brain areas in trans men, indicating potential neural differences that challenge binary gender models and highlight the unique neural characteristics present in those with gender dysphoria.
The production of ϒ(2S) and ϒ(3S) mesons in lead-lead (Pb-Pb) and proton-proton (pp) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The ϒ(3S) meson is observed for the first time in Pb-Pb collisions, with a significance above 5 standard deviations. The ratios of yields measured in Pb-Pb and pp collisions are reported for both the ϒ(2S) and ϒ(3S) mesons, as functions of transverse momentum and Pb-Pb collision centrality.

The search uses proton-proton collision data corresponding to an integrated luminosity of 138 fb^{-1} at sqrt[s]=13 TeV, collected at the CERN LHC. No significant deviations from the background predictions are observed between 1.
