The impact of the integration of digital platforms and active teaching strategies (Kahoot!) on the performance of Brazilian medical course students in the discipline of histology.

Teaching human histology is part of understanding the tissues of the human body and, therefore, it is part of the training curriculum of all health courses. The increase in technologies and active teaching methodologies has a positive impact on student learning, as it reduces the challenges present in the subject. Therefore, this work aimed to compare the performance of students in the histology discipline, when compared to traditional teaching methodology and its association with game-based learning and a basic histology teaching platform.

Phytol as an anticarcinogenic and antitumoral agent: An in vivo study in swiss mice with DMBA-Induced breast cancer.

Phytol (PHY) (3,7,11,15-tetramethylhexadec-2-en-1-ol) exhibits various pharmacological properties including toxicity and cytotoxicity, and exerts antitumor activity. Owing to the urgent need of new pharmaceutical formulations for breast cancer therapy, this study aimed at the evaluation of antitumor activity of PHY in 7,12-dimethylbenzanthracene-cancer-induced animal model. Comet assay was employed to evaluate the cytogenetics, DNA repair, and antigenotoxic activities of PHY in neoplastic (breast) and non-neoplastic rodent cells (bone marrow, lymphocytes, and liver).

AMPK activation promotes gastroprotection through mutual interaction with the gaseous mediators HS, NO, and CO.

Activation of 5' adenosine monophosphate-activated protein kinase (AMPK) stimulates production of the gaseous mediators nitric oxide (NO) and carbon monoxide (CO), which are involved in mucosal defense and gastroprotection. As AMPK itself has gastroprotective effects against several gastric ulcer etiologies, in the present study, we aimed to elucidate whether AMPK may also prevent ethanol-induced injury and play a key role in the associated gastroprotection mediated by hydrogen sulfide (HS), NO, and CO. Mice were pretreated with AICAR (20 mg/kg, an AMPK activator) alone or with 50% ethanol.

This study aims at evaluation of the mutagenic effect of pesticide exposure to agricultural workers through chromosomal aberrations (CA) and micronucleus (MN) assay in peripheral blood lymphocytes and oral mucosal cells, respectively.

Diterpenes as lead molecules against neglected tropical diseases.

Nowadays, neglected tropical diseases (NTDs) are reported to be present everywhere. Poor and developing areas in the world have received great attention to NTDs. Drug resistance, safety profile, and various challenges stimulate the search for alternative medications.

Diminazene aceturate, an angiotensin-converting enzyme II activator, prevents gastric mucosal damage in mice: Role of the angiotensin-(1-7)/Mas receptor axis.

The angiotensin (Ang) II converting enzyme (ACE II) pathway has recently been shown to be associated with several beneficial effects in various organisms, including gastroprotection. ACE II is responsible for converting Ang II into an active peptide, Ang-(1-7), which in turn binds the Mas receptor. Recent studies have shown that diminazene aceturate (Dize) a trypanocidal used in animals, activates ACE II.

Pentoxifylline reduces the inflammatory process in diabetic rats: relationship with decreases of pro-inflammatory cytokines and inducible nitric oxide synthase.

Studies suggest that inflammation is a key factor in the pathogenesis of diabetes mellitus. Pro-inflammatory cytokines, such as IL-6 and TNF-alpha, are produced by adipose tissue in large quantities, in obese and especially in diabetic individuals. Pentoxifylline (PTX) is a non-selective phosphodiesterase inhibitor with anti-inflammatory and antioxidant actions that may contribute to alleviate diabetes side effects, as neuropathy, retinopathy and nephropathy.

Pentoxifylline decreases glycemia levels and TNF-alpha, iNOS and COX-2 expressions in diabetic rat pancreas.

Pentoxifylline (PTX), a methyl xanthine derivative, is a phosphodiesterase inhibitor with anti-inflammatory and renoprotective effects in diabetic patients, among other properties. We studied PTX actions and mechanisms in reducing blood biochemical parameters, in diabetic rats. For diabetes induction, alloxan was intravenously administered to male Wistar rats.
