Knowledge of caregivers and factors associated with neuropsychomotor development in children.

Objectives: to analyze the knowledge of caregivers and the factors associated with neuropsychomotor development in children.

Methods: a cross-sectional study, with a quantitative approach, was conducted with 220 child-caregiver binomials attended in the public health services of the municipality of Parnaíba, State of Piauí. The study used the "Denver Test II" and the "Inventory of Child Development Knowledge".

Phosphatidylinositol 3-kinase gamma participates in nimesulide-induced hepatic damage.

Objective: To evaluate the participation of the phosphatidylinositol 3-kinase pathway in the liver damage caused by nimesulide.

Methods: Liver damage been induced by nimesulide. Mice were treated with either 2% dimethyl sulfoxide or AS605240, a phosphatidylinositol 3-kinase gamma pathway antagonist.

Photobiomodulation exerts anti-inflammatory effects on the vascular and cellular phases of experimental inflammatory models.

Photobiomodulation therapy (PBMT) is a non-thermal therapeutic procedure widely used in clinical practice. It is considered an effective modality of treatment for the control of various inflammatory conditions with fewer adverse effects as compared to conventional therapy. However, despite the clinical effects, the mechanisms of action and dosimetric parameters of PBMT are not fully understood.

Transcranial Direct Current Stimulation Combined With Therapeutic Exercise in Chronic Low Back Pain: Protocol of a Randomized Controlled Trial.

Objective: Although some studies have shown the clinical benefits of therapeutic exercise in chronic nonspecific low back pain, the effect sizes are generally small to moderate and recurrence rates are high. Transcranial direct current stimulation (tDCS) has been used to modulate pain-processing systems and motor outputs and has the potential to optimize the clinical benefits of therapeutic exercise. However, evidence for this combination is still lacking.

Chemical structure and anti-inflammatory effect of polysaccharide extracted from Morinda citrifolia Linn (Noni).

Polysaccharides extracted from plants are very promising molecules in the field of pharmacotherapy. Knowing this, the aim of this study was to extract, characterize and evaluate the action of the polysaccharide of Morinda citrifolia Linn (Noni-PLS) in biological models of inflammatory processes. The characterization tests shown that sample refers to a heteropolysaccharide composed mainly of homogalacturonan and rhamnogalacturonan.

Photobiomodulation reduces neutrophil migration and oxidative stress in mice with carrageenan-induced peritonitis.

The purpose of the study is to investigate the effects of two doses of photobiomodulation (PBM) on inflammatory parameters including cell migration and oxidative stress in carrageenan-induced peritonitis models. Twenty-eight mice were divided into four groups: saline; untreated carrageenan (Cg; inflammation induced); and PMB treatment groups L1 and L5 (inflammation induced with carrageenan followed by laser irradiation at 1 and 5 J/cm, respectively). After 30 min of inducing inflammation, laser irradiation was administered every hour, for 4 h.

Collagen-based silver nanoparticles: Study on cell viability, skin permeation, and swelling inhibition.

Collagen is considered the most abundant protein in the animal kingdom, comprising 30% of the total amount of proteins and 6% of the human body by weight. Studies that examine the interaction between silver nanoparticles and proteins have been highlighted in the literature in order to understand the stability of the nanoparticle system, the effects observed in biological systems, and the appearance of new chemical pharmaceutical products. The objective of this study was to analyze the behavior of silver nanoparticles stabilized with collagen (AgNPcol) and to check the skin permeation capacity and action in paw edema induced by carrageenan.

Effects of 5-fluorouracil in nuclear and cellular morphology, proliferation, cell cycle, apoptosis, cytoskeletal and caveolar distribution in primary cultures of smooth muscle cells.

Colon cancer is one of the most prevalent types of cancer in the world and is one of the leading causes of cancer death. The anti-metabolite 5- fluorouracil (5-FU) is widely used in the treatment of patients with colon cancer and other cancer types. 5-FU-based chemotherapy has been shown to be very efficient in the improvement of overall survival of the patients and for the eradication of the disease.
