Vasoactive intestinal peptide promotes hypophagia and metabolic changes: Role of paraventricular hypothalamic nucleus and nitric oxide.

Vasoactive intestinal peptide (VIP), a neuromodulator present in the hypothalamus, plays an important role in the regulation of food intake. Paraventricular nucleus of the hypothalamus (PVN) is involved in ingestive responses and regulates the nitric oxide (NO) pathway. The main objectives of this study were to investigate metabolic changes established after different doses and times of VIP microinjection on the PVN, and the effect of VIP microinjection on the PVN on food intake and the role of NO in this control.

Evaluation of hepatic and renal effects in rat dams and their offspring after exposure to paracetamol during gestation and lactation.

Paracetamol (PAR) is the analgesic and antipyretic of choice for pregnant and nursing women. PAR may reach the fetus and/or neonate through the placenta and/or milk and effect development. This study evaluated possible hepatic and renal effects in rat dams and their offspring exposed to PAR using a human-relevant route of administration and doses from Gestational Day 6 to Postnatal Day (PND) 21.

Effect of the platelet-rich plasma covering of polypropylene mesh on oxidative stress, inflammation, and adhesions.

Introduction And Hypothesis: Polypropylene mesh (PPM) is often used for urogynecological repair; however, it can cause complications. An approach to reduce complications is to coat PPM with anti-inflammatory and wound-healing molecules. Platelet-rich plasma (PRP) is inexpensive and improves wound healing.

The flavonoid quercetin inhibits titanium dioxide (TiO)-induced chronic arthritis in mice.

Titanium dioxide (TiO) is a common component of orthopedic prosthesis. However, prosthesis wear releases TiO, which induces inflammation and osteolysis in peri-prosthetic tissues. Quercetin is a flavonoid widely present in human diet, which presents biological activities such as antinociceptive, anti-inflammatory and antioxidant effects.
