Acupuncture reduces peripheral and brainstem cytokines in rats subjected to lipopolysaccharide-induced inflammation.

Background: Lipopolysaccharide (LPS) endotoxins are activators of innate immunity inducing infection and inflammatory responses. Anti-inflammatory drugs can have undesirable side effects. Acupuncture may be an alternative for the treatment of inflammatory processes.

Physical and cognitive training are able to prevent recognition memory deficits related to amyloid beta neurotoxicity.

Alzheimer's disease (AD) is characterized by the presence of amyloid-β (Aβ), oxidative damage and neuronal degeneration, which, together with other pathological events, promote progressive memory loss and cognitive decline. Non-pharmacological strategies have been study to provide some protection against the development of AD. Considering that physical exercise neuroprotective effects on prevention of cognitive deficits are well elucidate, it is important clarify the effects of cognitive training, and verify if they are similar or comparable to those observed for physical exercise.

Electrical stimulation attenuates morphological alterations and prevents atrophy of the denervated cranial tibial muscle.

Objective: To investigate if electrical stimulation through Russian current is able to maintain morphology of the cranial tibial muscle of experimentally denervated rats.

Methods: Thirty-six Wistar rats were divided into four groups: the Initial Control Group, Final Control Group, Experimental Denervated and Treated Group, Experimental Denervated Group. The electrostimulation was performed with a protocol of Russian current applied three times per week, for 45 days.

Effects of controlled doses of Oxyelite Pro on physical performance in rats.

Background: OxyElite Pro (OEP) is a dietary supplement to increase metabolism which contains as key stimulant the ingredient 1,3-dimethylamylamine (DMAA). Serious adverse effects have been reported after OEP consumption however, these effects are related to poisoning or overdose. To our knowledge, no one studied the effects of OEP at controlled doses.

The new heterologous fibrin sealant in combination with low-level laser therapy (LLLT) in the repair of the buccal branch of the facial nerve.

This study aimed to evaluate the effects of low-level laser therapy (LLLT) in the repair of the buccal branch of the facial nerve with two surgical techniques: end-to-end epineural suture and coaptation with heterologous fibrin sealant. Forty-two male Wistar rats were randomly divided into five groups: control group (CG) in which the buccal branch of the facial nerve was collected without injury; (2) experimental group with suture (EGS) and experimental group with fibrin (EGF): The buccal branch of the facial nerve was transected on both sides of the face. End-to-end suture was performed on the right side and fibrin sealant on the left side; (3) Experimental group with suture and laser (EGSL) and experimental group with fibrin and laser (EGFL).
