Knowledge and sexual behaviors: A path towards HIV/AIDS prevention among university students.

Despite the world's commitment to end HIV/AIDS by 2030, the disease is still prevalent in sub-Saharan Africa. Although awareness is high among the youth, they are the most vulnerable because of their susceptibility to risky behaviors. This cross-sectional correlational study examined HIV/AIDS awareness and sexual behaviors among university students.

Transport cost to port though Brazilian federal roads network: Dataset for years 2000, 2005, 2010 and 2017.

Transport costs can play a significant role in agricultural exports and businesses profitability. It can also influence farmers' decisions regarding cropland expansion, intensification or land abandonment. Thus, transport is useful to take into account when modeling and evaluating land use and cover change related to agriculture production.

In vivo confocal microscopy assessment of the corneoscleral limbal stem cell niche before and after biopsy for cultivated limbal epithelial transplantation to restore corneal epithelium.

Autologous cultivated limbal epithelial transplantation (CLET) is a successful therapy to restore corneal epithelium when limbal epithelial stem cells are damaged unilaterally, which can result in corneal blindness. We used in vivo confocal microscopy (IVCM) to identify the best location in the corneoscleral limbal niche and to harvest autologous epithelial stem cells for CLET. We also ascertained the completeness of limbal structure removal after biopsy and followed the healing process for any evidence of limbal structure reappearance.

Simplified progressive approach for the ablation of scar related atrial macroreentrant tachycardias.

Introduction: Radiofrequency ablation of scar related right atrial flutter is challenging. Long procedures, prolonged fluoroscopic times and high percentages of recurrences are of concern. We present a simple and progressive approach based on a single electroanatomic map of the right atrium.
