Photonic platform coupled with machine learning algorithms to detect pyrolysis products of crack cocaine in saliva: A proof-of-concept animal study.

The non-invasive detection of crack/cocaine and other bioactive compounds from its pyrolysis in saliva can provide an alternative for drug analysis in forensic toxicology. Therefore, a highly sensitive, fast, reagent-free, and sustainable approach with a non-invasive specimen is relevant in public health. In this animal model study, we evaluated the effects of exposure to smoke crack cocaine on salivary flow, salivary gland weight, and salivary composition using Attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy.

Neonatal puppies and kittens have physiological and anatomical characteristics that differ from those of adult animals, which impacts the interpretation of physical examination and complementary tests. The veterinarian must be familiar with the clinical, laboratory, and imaging aspects observed in neonates. It is necessary to thoroughly evaluate the litter and the mother to notice the most subtle signs of illness and advise the owner to constantly monitor the newborns, quickly sending them to specialized care.

Histomorphometric and Micro-CT Evaluation of Cerabone and Bio-Oss in Maxillary Sinus Lifting: A Randomized Clinical Trial.

: The loss of teeth in the posterior maxillary region often leads to significant alveolar bone resorption and maxillary sinus pneumatization, complicating dental implant placement. Maxillary sinus grafting, typically using autogenous bone, is a common solution. However, autogenous bone grafts require additional surgical procedures, leading to increased morbidity.

The Methodological Quality of Studies on Physical Exercise in Adolescents with Cerebral Palsy: A Scoping Review of Systematic Reviews and Meta-Analyses.

Introduction: Systematic reviews and meta-analyses point to the benefits of physical exercise for adolescents with cerebral palsy, improving physical conditioning, muscle strength, balance, and walking speed. However, given the high number of reviews that include randomized and non-randomized studies, it is increasingly necessary to assess the methodological quality of these reviews. This scoping review investigated the methodological quality of systematic reviews and meta-analyses on the effects of physical exercise in adolescents with cerebral palsy to elucidate the methodological limitations of the research and the priorities to be observed in future research.

Influence of polymorphisms on the phenotype of TLR1, TLR4 and TLR9 genes and their association with cervical cancer: Bioinformatics prediction analysis and a case-control study.

Susceptibility to cervical cancer has been associated with Toll-like receptors (TLRs), which is an important component of innate immunity. According to previous studies, polymorphisms in TLRs genes can affect immune response pathways and lead to the development of cervical cancer. The present study aims to evaluate the functionality of polymorphisms in TLR1, TLR4 and TLR9 genes and their associations with cervical cancer.

The Multitarget Action of Vitamins in the Ischemic Stroke.

A stroke, also known as a cerebral hemorrhage, occurs when there is an interruption in the blood supply to a part of the brain, resulting in damage to brain cells. This issue is one of the leading causes of death in developed countries, currently killing about 5 million people annually. Individuals who survive ischemic stroke often face serious vision problems, paralysis, dementia, and other sequelae.

Analysis of environmental variables and deforestation in the amazon using logistical regression models.

In this study, we applied a multivariate logistic regression model to identify deforested areas and evaluate the current effects on environmental variables in the Brazilian state of Rondônia, located in the southwestern Amazon region using data from the MODIS/Terra sensor. The variables albedo, temperature, evapotranspiration, vegetation index, and gross primary productivity were analyzed from 2000 to 2022, with surface type data from the PRODES project as the dependent variable. The accuracy of the models was evaluated by the parameters area under the curve (AUC), pseudo R, and Akaike information criterion, in addition to statistical tests.
