The effects of elastic tubing-based resistance training compared with conventional resistance training in patients with moderate chronic obstructive pulmonary disease: a randomized clinical trial

Objective: To investigate the effects of elastic tubing training compared with conventional resistance training on the improvement of functional exercise capacity, muscle strength, fat-free mass, and systemic inflammation in patients with chronic obstructive pulmonary disease.Design: A prospective, randomized, eight-week clinical trial.Setting: The study was conducted in a university-based, outpatient, physical therapy clinic.Subjects: A total of 49 patients with moderate chronic obstructive pulmonary disease.Interventions: Participants were randomly assigned to perform elastic tubing training or conventional resistance training three times per week for eight weeks.Main measures: The primary outcome measure was functional exercise capacity. The secondary outcome measures were peripheral muscle strength, health-related quality of life assessed by the Chronic Respiratory Disease Questionnaire (CRDQ), fat-free mass, and cytokine profile.Results: After eight weeks, the mean distance covered during six minutes increased by 73 meters (69) in the elastic tubing group and by 42 meters (+/- 59) in the conventional group (p < 0.05). The muscle strength and quality of life improved in both groups (P < 0.05), with no significant differences between the groups. There was a trend toward an improved fat-free mass in both groups (P = 0.05). After the first and last sessions, there was an increase in interleukin 1 (IL-1) and interleukin 10 (IL-10) in both groups, while tumour necrosis factor alpha (TNF-) was stimulated only in the conventional training group.Conclusion: Elastic tubing training had a greater effect on functional exercise capacity than conventional resistance training. Both interventions were equally effective in improving muscle strength and quality of life.

Efeito da silibinina sobre o fator de transcrição nuclear-kB e produção de citocinas inflamatórias por células mononucleares de gestantes portadoras de pré-eclâmpsia

Pre-eclampsia (PE) is a complication of human pregnancy characterized by hypertension and proteinuria after 20 weeks of gestation. Its incidence varies from 5% to 7% of pregnancies and is a major cause of morbidity and maternal and fetal mortality. This is a multisystemic disease, with focus on vascular dysfunction and is closely related to the exacerbated activation of the immune system. In addition to increased activation of monocytes and granulocytes, there is an elevated production of proinflammatory cytokines in pregnant women with PE. The nuclear transcription factor-kB (NF-kB) is present in the cells of the immune system and is responsible for transcription of genes related to inflammation. Whereas the PE is associated with intense inflammatory response, the use of substances modulating the activity of NF-kB factor could be useful in alleviating the inflammation present in these patients. Silibinin is the main component of silymarin, a polyphenolic extract obtained from fruits and seeds of Sylibum marianum with potent hepatoprotective, anti-inflammatory and anti-fibrotic activities. The silibinin mechanism of action includes the ability to inhibit NF-kB activation and, consequently, its migration to the nucleus. The objective of this study was to assess whether silibinin modulates the activity of NF-kB and the production of inflammatory cytokines in mononuclear cells of patients with PE. We evaluated 34 pregnant women with PE, 20 normotensive pregnant women (GN) and 15 non-pregnant women (NG). Peripheral blood mononuclear cells (PBMC) were obtained from those groups of women and cultured in the presence or absence of silibinin (5 uM or 50 uM) and stimulated or not with lipopolysaccharide (LPS) for 18 h to obtain supernatant for determination of tumor necrosis factor-alpha (TNF-α) and interleukin-1 (IL-1β) by enzyme immunoassay (ELISA). The cells were...(Complete abstract click electronic access below)

Antimicrobial photodynamic therapy as an adjunct to non-surgical treatment of aggressive periodontitis: a split-mouth randomized controlled trial

Background: The management of aggressive periodontitis (AgP) represents a challenge for clinicians because there are no standardized protocols for an efficient control of the disease. This randomized controlled clinical trial evaluated the effects of repeated applications of antimicrobial photodynamic therapy (aPDT) adjunctive to scaling and root planing (SRP) in patients with AgP. Methods: Using a split-mouth design, 20 patients with generalized AgP were treated with aPDT + SRP (test group) or SRP only (control group). aPDT was applied at four periods. All patients were monitored for 90 days. Clinical, microbiologic, and immunologic parameters were statistically analyzed. Results: In deep periodontal pocket analysis (probing depth [PD] >= 7 mm at baseline), the test group presented a decrease in PD and a clinical attachment gain significantly higher than the control group at 90 days (P < 0.05). The test group also demonstrated significantly less periodontal pathogens of red and orange complexes and a lower interleukin-1 beta/interleukin-10 ratio than the control group (P < 0.05). Conclusion: The application of four sessions of aPDT, adjunctive to SRP, promotes additional clinical, microbiologic, and immunologic benefits in the treatment of deep periodontal pockets in single-rooted teeth in patients with AgP.

Alterations in the water intake caused by central inhibition of angiotensin-converting enzyme in the rat

In the present study we investigated the effects of central (i.c.v.) and subcutaneous (s.c.) injections of a 2 μg dose of lisinopryl, an inhibitor of angiotensin I(ANGI)-converting enzyme (CE), on water intake. I.c.v. but not s.c. injection of lisinopryl abolished drinking in response to s.c. isoprenaline (100 μg/kg) and significantly reduced drinking in response to 24 h water deprivation or s.c. polyethylene glycol (30% w/v, 10 ml/kg). Lisinopryl had no effect on water intake induced by cellular dehydration (s.c. injection of hypertonic saline (2 M NaCl)). These results are consistent with the hypothesis that lisinopryl acts as a CE blocking agent in the brain. The thirst challenge induced by hypotension using isoprenaline acts primarily by generating ANGII systemically and centrally. The other thirst challenges such as cellular dehydration are independent of the ANGII in the brain. This conclusion was made possible by utilizing a new CE blocking agent at a smaller dose than normally used for other ANG I-CE inhibitors. © 1992.
