Effects of Transcutaneous Electrical Nerve Stimulation on Pain, Pulmonary Function, and Respiratory Muscle Strength After Posterolateral Thoracotomy: A Randomized Controlled Trial.

Purpose: To evaluate the effects of transcutaneous electrical nerve stimulation (TENS) compared to placebo TENS and a control group on pain, pulmonary function, respiratory muscle strength, and analgesic medications in the postoperative period of thoracotomy in an Intensive care unit (ICU).

Methods: Patients who had undergone posterolateral thoracotomy were randomly allocated to receive TENS during ICU stay, or placebo TENS, or into the control group. All groups received conventional physiotherapy.

Safety and potential benefits of physical therapy in adult patients on extracorporeal membrane oxygenation support: a systematic review.

Scientific and technological advances, coupled with the work of multidisciplinary teams in intensive care units, have increased the survival of critically ill patients. An essential life support resource used in intensive care is extracorporeal membrane oxygenation. Despite the increased number of studies involving critically ill patients, few studies to date have demonstrated the safety and benefits of physical therapy combined with extracorporeal membrane oxygenation support.

Thiol/disulfide status regulates the activity of thiol-containing kinases related to energy homeostasis in rat kidney.

Considering that thiol-containing enzymes like kinases are critical for several metabolic pathways and energy homeostasis, we investigated the effects of cystine dimethyl ester and/or cysteamine administration on kinases crucial for energy metabolism in the kidney of Wistar rats. Animals were injected twice a day with 1.6 µmol/g body weight cystine dimethyl ester and/or 0.

Expiratory rib cage compression in mechanically ventilated adults: systematic review with meta-analysis.

Objective:: To review the literature on the effects of expiratory rib cage compression on ventilatory mechanics, airway clearance, and oxygen and hemodynamic indices in mechanically ventilated adults.

Methods:: Systematic review with meta-analysis of randomized clinical trials in the databases MEDLINE (via PubMed), EMBASE, Cochrane CENTRAL, PEDro, and LILACS. Studies on adult patients hospitalized in intensive care units and under mechanical ventilation that analyzed the effects of expiratory rib cage compression with respect to a control group (without expiratory rib cage compression) and evaluated the outcomes static and dynamic compliance, sputum volume, systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, peripheral oxygen saturation, and ratio of arterial oxygen partial pressure to fraction of inspired oxygen were included.

Alternative Physical Therapy Protocol Using a Cycle Ergometer During Hospital Rehabilitation of Coronary Artery Bypass Grafting: a Clinical Trial.

Objective: To compare the efficacy of a cycle ergometer-based exercise program to a standard protocol on the increment of the maximum distance walked during the six-minute walk test in the postoperative rehabilitation of patients submitted to coronary artery bypass grafting.

Methods: A controlled clinical trial pilot, blinded to the outcome, enrolled subjects who underwent coronary artery bypass grafting in a hospital from Southern Brazil. Subjects were designated for the standard physical rehabilitation protocol or to an alternative cycle ergometer-based protocol through simple random sampling.

The effect of exercise on the oxidative stress induced by experimental lung injury.

Aim: The effects of physical exercise on oxidative stress parameters and immunocontent of NF-кβ/p65 in lung of rats submitted to lung injury, as well as its possible protective effect on the changes in the alveolar-capillary barrier (total cell count, lactate dehydrogenase and total protein) in the bronchoalveolar lavage fluid (BALF) and the inflammatory infiltration in the pulmonary parenchyma were evaluated.

Main Methods: Wistar rats were submitted to two months of physical exercise and after this period, lung injury was induced by intratracheal instillation of lipopolysaccharide (dose of 100 μg/100 g body weight). Twelve hours after injury, the animals were sacrificed and lung and BALF were collected.

Effects of cysteamine on oxidative status in cerebral cortex of rats.

Cystinosis is a systemic genetic disease caused by a lysosomal transport deficiency accumulating cystine in most tissues. Tissue damage depends on cystine accumulation, but the mechanisms of this damage are still obscure. Cysteamine administration depletes cystine accumulated, increasing survive of affected patients.

Antioxidant effect of cysteamine in brain cortex of young rats.

Cysteamine is a cystine-depleting drug used in the treatment of cystinosis, a metabolic disorder caused by deficiency of the lysosomal cystine carrier. As a result, cystine accumulates within lysosomes in many tissues and organs, including the nervous system. Studies with cystine dimethyl ester loaded cells suggest that cystine might induce apoptosis through oxidative stress.

Evaluation of renal enzymuria and cellular excretion as an marker of acute nephrotoxicity due to an overdose of paracetamol in Wistar rats.

Introduction: The present study was conducted to determine whether the urinary levels of excreted enzymes, gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), aspartate (AST) and alanine aminotransferases (ALT), can efficiently indicate, within 24 h, an acute nephrotoxicity due to an overdose of paracetamol (PAR).

Methods: A baseline urine was collected from the experimental group. Thereafter, blood collected from the orbital sinus (1.

Proline reduces creatine kinase activity in the brain cortex of rats.

Type II hyperprolinemia is an inherited disorder caused by a deficiency of delta 1-pyrroline-5-carboxilic acid dehydrogenase, whose biochemical hallmark is proline accumulation in plasma and tissues. Although neurological symptoms occur in most patients, the neurotoxicity of proline is still controversial. The main objective of the present study was to investigate the effect of acute and chronic administration of proline on creatine kinase activity of brain cortex of Wistar rats.

Effect of proline on creatine kinase activity in rat brain.

Type II Hyperprolinemia is an inherited disorder caused by a deficiency of delta1-pyrroline-5-carboxilic acid dehydrogenase, whose biochemical hallmark is proline accumulation in plasma and tissues. Although neurologic symptoms occur in most patients, the neurotoxicity of proline is still controversial. The main objective of this study was to investigate the effect of acute and chronic administration of proline on creatine kinase activity in the homogenates of cerebellum and midbrain from Wistar rats.

Hyperphenylalaninemia reduces creatine kinase activity in the cerebral cortex of rats.

Phenylketonuria (PKU) is a metabolic disorder accumulating phenylalanine (Phe) and its metabolites in plasma and tissues of the patients. Considering that phenylalanine is the main neurotoxic metabolite, and brain energy homeostasis seems to be affected in phenylketonuria, our main objective was to investigate the effect of acute and chronic hyperphenylalaninemia (HPA) on creatine kinase (CK) activity in brain cortex of Wistar rats. Hyperphenylalaninemia was induced by subcutaneous administration of 5.
