Periodontal ageing and its management via pharmacological glucose modulation.

Periodontal disease (PD), a widespread non-communicable disease, affects over 90% of the global population with no known cure. Current management strategies focus on the stabilisation of disease progression, which is successfully achieved to a limited extent. Yet the never-ending battle between bacteria and the gingiva involves a complex interplay between genetic, microbial and environmental factors, demanding innovative approaches to improve the prevention and stabilisation of this disease.

Modulation of sirtuin expression by a high-sugar diet and regular swimming trained precedes the loss of kidney function.

Sirtuins (SIRTs) are key regulators of cellular metabolism, involved in a wide range of physiological and pathological processes. However, there is scarce knowledge about the effect of sugar consumption and physical activity on SIRTs in kidney disorders. Here, we evaluated the impact of prolonged consumption of an isocaloric high-sugar diet (HSD) and physical training on the modulation of renal Sirts and the link between these alterations and possible obesity-associated kidney damage.

The Use of Nanosecond Pulsed Fibre Laser Treatment to Improve the Corrosion Resistance of 316L SS Utilised as Surgical Devices.

The nanosecond pulsed fibre laser (NsPFL) treatment is extensively employed to distinguish hospital surgical instruments (micro-surgical forceps, surgical blades, orthopaedic drills, and high-precision laparoscopic tools), which are generally composed of stainless steel. Nevertheless, if the laser parameters are not properly optimised, this process may unintentionally provoke corrosion. Maintaining the structural integrity of these materials is essential for ensuring patient safety and minimising long-term costs.

vCPP2319 interacts with metastatic breast cancer extracellular vesicles (EVs) and transposes a human blood-brain barrier model.

Brain metastases (BM) are frequently found in cancer patients and, though their precise incidence is difficult to estimate, there is evidence for a correlation between BM and specific primary cancers, such as lung, breast, and skin (melanoma). Among all these, breast cancer is the most frequently diagnosed among women and, in this case, BM cause a critical reduction of the overall survival (OS), especially in triple negative breast cancer (TNBC) patients. The main challenge of BM treatment is the impermeable nature of the blood-brain barrier (BBB), which shields the central nervous systems (CNS) from chemotherapeutic drugs.

Predisposing factors for symptoms of anxiety, depression, and insomnia in university students.

Objectives: to characterize the sociodemographic and psychological aspects of university students who sought psychiatric care at a Student Support Center of a Federal University and to analyze associations between mental health issues and predisposing factors.

Methods: a retrospective analysis of 103 medical records was conducted. The statistical analysis consisted of two steps: a descriptive analysis and a predictive analysis using the Logistic Regression Model.
