Let's shed light on photogenotoxicity.

Photosensitization reactions caused by ultraviolet and visible radiation (UV-vis) absorbing chemicals can induce DNA damage through direct and indirect mechanisms. In this context, the investigation of phototoxicity is an essential part of the toxicological assessment programs for drugs, cosmetics and other chemicals that may be exposed to UV-vis light. The current battery of photosafety assessment tests includes an initial investigation of their photoreactive potential followed by in vitro phototoxicity testing.

The effect of hyperbaric oxygen therapy on psychological state and wound healing: a case report.

CRISPR technology towards genome editing of the perennial and semi-perennial crops citrus, coffee and sugarcane.

Gene editing technologies have opened up the possibility of manipulating the genome of any organism in a predicted way. CRISPR technology is the most used genome editing tool and, in agriculture, it has allowed the expansion of possibilities in plant biotechnology, such as gene knockout or knock-in, transcriptional regulation, epigenetic modification, base editing, RNA editing, prime editing, and nucleic acid probing or detection. This technology mostly depends on tissue culture and genetic transformation/transfection protocols, which sometimes become the major challenges for its application in different crops.

Use of in silico and in vitro methods as a potential new approach methodologies (NAMs) for (photo)mutagenicity and phototoxicity risk assessment of agrochemicals.

The increased use of agrochemicals raises concerns about environmental, animal, and mainly human toxicology. The development of New Approach Methodologies (NAMs) for toxicological risk assessment including new in vitro tests and in silico protocols is encouraged. Although agrochemical mutagenicity testing is well established, a complementary alternative approach may contribute to increasing reliability, with the consequent reduction of false-positive results that lead to unnecessary use of animals in follow-up in vivo testing.

Ergonomic risk assessment of surgeon's position during radical prostatectomy: Laparoscopic versus robotic approach.

Background And Objectives: Radical prostatectomy (RP) is a definitive surgical therapy for localized prostate cancer. Evidence suggests that the poor ergonomics of surgeons during RP may lead to work-related musculoskeletal disorders and loss of productivity. Since each surgery modality has its physical demands, we compared the ergonomic risk between laparoscopic (LRP) and robotic-assisted (RARP) radical prostatectomy.

Can SARS-CoV-2 screening in oral biopsies aid epidemiological surveillance?

Background: Three years after the first confirmed COVID-19 case in Brazil, the outcomes of Federal government omissions in managing the crisis and anti-science stance heading into the pandemic have become even more evident. With over 36 million confirmed cases and nearly 700 000 deaths up to January 2023, the country is one of the hardest-hit places in the world. The lack of mass-testing programs was a critical broken pillar responsible for the quick and uncontrolled SARS-CoV-2 spread throughout the Brazilian population.

Targeting N-type calcium channels in young-onset of some neurological diseases.

Calcium (Ca ) is an important second messenger in charge of many critical processes in the central nervous system (CNS), including membrane excitability, neurotransmission, learning, memory, cell proliferation, and apoptosis. In this way, the voltage-gated calcium channels (VGCCs) act as a key supply for Ca entry into the cytoplasm and organelles. Importantly, the dysregulation of these channels has been reported in many neurological diseases of young-onset, with associated genetic factors, such as migraine, multiple sclerosis, and Huntington's disease.
