Article Synopsis
- This study focuses on the presence of human polyomaviruses (HPyV) in head and neck squamous cell carcinoma (SCC) samples, particularly examining the role of these viruses alongside traditional risk factors like smoking and alcohol.
- Researchers analyzed 60 samples from different mouth and throat areas for four types of HPyV, finding a 60% positivity rate for JCPyV and low rates for MCPyV (5%) with no instances of BKPyV or TSPyV.
- The study concluded that while JCPyV is commonly present in oral cavity and oropharyngeal SCC, no strong links to patient demographics or clinical characteristics were found, except for a notable association between JCP
In this paper, we looked at the effect of mobility by students, post-doctorates and professors on science in Brazil. We analysed CAPES, CNPq, FAPESP and Incites data to examine the number of scholarships and their impact on posterior publishing. Decision trees, including the region of the country, length of stay by student and Professor, as well as institution abroad, were evaluated, along with logistic regressions.

Article Synopsis
- Brazil is a leading beef producer, and the Montana breed is favored for its high meat quality and adaptability to tropical climates, setting it apart from other breeds like Zebu and Taurine.
- A study mapped 16 farms in five Brazilian states to analyze the relationship between genetic data (SNP) and the geographical location of livestock using ArcGIS and AIS software.
- The findings indicate a correlation between genetic and geographical distances, highlighting how geography influences genetic diversity, which is important for improving agricultural practices in Brazil.*
In response to the growing need for sustainable analytical methods, this study explores the repurposing of screen-printed electrodes (SPEs) that would otherwise be discarded. This involves recoating the working electrode surface with a graphite (Gr) and chitosan (CTS) dispersion, creating a reusable SPE (SPE-Gr/CTS). Demonstrating its utility, SPE-Gr/CTS was employed for the detection of 4-bromo-2,5-dimethoxyphenethylamine (2C-B), a phenylethylamine commonly used for recreational proposes.

The study's objective was to determine if the infrared thermography is adequate for predicting the emission of CH in hair sheep and the best time after feeding to carry out the measurement. Twelve Santa Inês lambs (females, non-pregnant, with twelve months old and mean body weight of 39.
