O objetivo do estudo foi investigar os efeitos da dieta hiperlipídica e do treinamento de natação e força sobre o tecido adiposo, perfil lipídico e sistema endocanabinóide de ratos obesos exógenos. Para isso, utilizamos sessenta ratos adultos machos divididos em seis grupos: Sedentário Padrão (SP); Sedentário Hiperlipídico (SH); Natação Padrão (NP); Natação Hiperlipídica (NH); Força Padrão (FP); Força Hiperlipídica (FH). Após três semanas recebendo dieta padrão ou hiperlipídica, os animais iniciaram os protocolos de exercício. Os grupos NP e NH nadaram 60 minutos/dia, 5 dias/semana com carga de 5% do peso corporal atada ao corpo, em tanques de 50x30 cm, durante 8 semanas. Os grupos FP e FH realizaram exercício de subida em escada com pesos atados às suas caudas, uma vez a cada três dias, durante 8 semanas. Os animais dos grupos SP e SH continuaram sedentários e alimentados com suas respectivas dietas. A dieta hiperlipídica aumentou o ganho de massa corporal, peso relativo dos tecidos adiposos (epididimal, retroperitoneal, visceral e subcutâneo) e área de adipócitos (epididimal, retroperitoneal e visceral). Também aumentou o percentual de gordura de todos os tecidos adiposos e fígado, além de aumentar a expressão gênica do receptor CB1. Os grupos treinados apresentaram menores valores de área de adipócitos, melhora do perfil lipídico, menores valores no percentual de gordura dos tecidos adiposos e fígado, menores ganhos de massa corporal, além de menores expressão gênica do receptor CB1. Assim nossos resultados indicam os potenciais benefícios do treinamento força e natação, como alternativas não farmacológicas para controlar os efeitos deletérios da dieta hiperlipídica sobre o tecido adiposo, perfil lipídico, conteúdo lipídico e controle do desequilíbrio do sistema endocanabinóide provocado pela dieta hiperlipídica.

Alopecia can be caused by a variety of reasons, both intrinsic (organic) and extrinsic (environmental), including a lack of vitamin complexes, stress, hormonal abnormalities, genetic inheritance, chemical effects, and medication use. The use of antioxidant shampoos and conditioners with hair stimulation has become common practise in Brazil.The most common is androgenetic alopecia (AGA), which causes premature fillet unit ageing, follicle micro-inflammation, and hair growth inhibition. (AGA) is a slow, painless and silent micro-inflammation triggered by factors such as climbing, chemical action caused by the use of cosmetics, body stress, hormonal disorders, menstrual irregularity, weight loss, systemic disease, use of medication to treat cancer and iron deficiency.The hair fibre growth cycle is harmed (catagen, telogen and anagen). So, a low-protein, low-vitamin diet is concerning; a multivitamin supplement is required. Today, medications are regarded as a watershed in the treatment of alopecia, associating a scheduled and targeted active induction technique. When using a mix of LED and Laser therapy, microagulching is vitally crucial. Calculated as men and women's complaints upon exposure to certain aspects of everyday life, as well as a decrease in the creation of reactive elements that might cause disruption and fall. It is recommended that nutritional supplements with antioxidant and anti-fall activity, as well as the use of growth factors, be used, as well as potential in-hibitors of hair ageing and with fall and alopecia. The goal of this study was to conduct a literature review on the scientific background and how aesthetic applications of antioxidants and growth factors in the treatment of alopecia can benefit patients.

Nowadays, the mesentery as a new organ was discovered. Mesenteric events may play an important role in the pathophysiology of several diseases. The aim of our study was investigate the synergic effects of ultrasound (US) and laser therapies on mesentery in obese-hyperglycemic rats. The 25 male Wistar rats were randomized into five groups. Obese nondiabetic (OND) group: obese rats without diabetes and no treatment conditions; SHAM group: obese-hyperglycemic rats treated with placebo; US group: obese-hyperglycemic rats treated with US; LASER group: obese-hyperglycemic rats treated with laser and; US+LASER group: obese-hyperglycemic rats treated with US plus laser. An animal model of type 2 diabetes based on a hyperlipidemic diet combined with a low dose of streptozotocin was used in this study. Body mass and biochemical measurements were performed. GOT and GPT level showed a significant reduction in the treated groups than SHAM. The total cholesterol, triglycerides and very low-density lipoprotein (VLDL) levels showed significantly lower values for the US+LASER group. There was also reduced risk of cardiovascular diseases evidenced by Castelli index in the treated groups than SHAM. This study showed that the US and laser treatment on mesentery resulted to an improvement in biochemical measurements of the obese-hyperglycemic rats, especially the total cholesterol, triglycerides and VLDL levels.

Obesity accumulates fat in the body may cause hypertension and change intracranial pressure waveform morphology (ICP). However, not clear how and when it occurs. Thus, our objective was to evaluate the ICP waveform morphology and P2/P1 ratio during the development of obesity. Sixteen 45-day-old male Wistar rats, after 60 days of adaptation were divided into non-obese (NOB, n = 7) and obese (OB, n = 9). The OB group received a high-fat diet and the NOB group received a standard diet for 24 weeks. ICP, body composition, blood pressure (BP), and heart rate(HR) were assessed every 4 weeks. Two-Way ANOVA was used for the area under the curve with Bonferroni's test, or Student's t-test for BP, and HR. Body mass(BM) and body fat(BF) and fat-free mass(FFM) were higher in OB rats. There was no difference in BP, but there was a difference in HR, greater in OB. The ICP decreased by NOB. These results suggest that the increase in BM and BF caused obesity, and BM can explain the increase in FFM. Although we did not find pathological states of ICP, NOB demonstrated better brain compliance, and the upward trend in the P2 waveform in OB may indicate impairment to the ICP of OB rats.

Obesity is an epidemic disease and the expansion of adipose tissue, especially visceral fat, promotes the secretion of factors that lead to comorbidities such as diabetes and cardiovascular diseases. Thus, diet and exercise have been proposed as an intervention to reverse these complications. An adipocytokine, known as irisin, mediates the beneficial effects of exercise. It has been proposed as a therapeutic potential in controlling obesity. In view of the above, this paper attempts to determine the modulation of irisin, visceral adiposity and biochemical markers in response to dietary intervention and aerobic exercise. To do this, 52 diet-induced obese male Wistar rats were divided into the following four groups: high-fat diet and exercise (HFD-Ex); HFD-Sedentary (HFD-Sed); chow-diet and exercise (CD-Exercise); and CD-Sed. The exercise-trained group performed a treadmill protocol for 60 min/day, 3 days/week for 8 weeks. Body mass (BM), body fat (BF), fat mass (FM), and fat-free mass (FFM) were analyzed. Mesenteric (MES), epididymal (EPI), and retroperitoneal (RET) adipose tissue was collected and histological analysis was performed. Biochemical irisin, triglycerides, glucose, insulin and inflammatory markers were determined and, FNDC5 protein expression was analyzed. In this study, the diet was the most important factor in reducing visceral adiposity in the short and long term. Exercise was an important factor in preserving muscle mass and reducing visceral depots after a long term. Moreover, the combination of diet and exercise can enhance these effects. Diet and exercise exclusively were the factors capable of increasing the values of irisin/FNDC5, however it did not bring cumulative effects of both interventions. Prescriptions to enhance the obesity treatments should involve reducing visceral adiposity by reducing the fat content in the diet associated with aerobic exercise.

Pancreatic lesions can produce metabolic disorders. Light-emitting diode (LED) has been used as a safe and effective phototherapy for cell proliferation and regeneration. We investigate the effects of phototherapy using LED irradiation on the pancreas after the injection of streptozotocin (STZ) to induce experimental diabetes and evaluate that the β cells can regenerate in the pancreas in an in vivo model and observe its implications on the control of carbohydrate metabolism. Twenty Wistar rats were randomized into three groups: non-diabetic control, diabetic control, and diabetic treated with LED. Except for the non-diabetic control group, all were induced to diabetes type I by streptozotocin injection. Treated groups were irradiated by LED: λ = 805 nm; 40 mW, 22 s; spot diameter 5 mm, spot area 0.196 cm2, 0.88 J that it was applied on pancreas projection area for 5 consecutive days and monitored for 30 days. Diabetic group treated with LED showed regeneration of islets and ducts (p = 0.001) on the pancreas. Intraperitoneal insulin tolerance test showed differences between the diabetic control and diabetic treated groups (p = 0.03). In diabetic control group, the hepatic glycogen content was 296% lower when compared with diabetic treated with LED. Furthermore, in the diabetic control group, the glycogen content of the gastrocnemius muscle was 706% smaller when compared with diabetic treated with LED. This study shows that LED was able to modify morphological and metabolic features and also altered carbohydrate metabolism on irradiated pancreas in experimental model of diabetes.

This study aims to analyze the effects of resisted, aerobic, and combined exercises on omentin levels in visceral adipose tissue and muscle of rats with experimental diabetes to verify whether these adipokines are related to the glucose pathway and inflammation process in this model. Male Wistar rats received a high-fat diet for 4 weeks and a low dose of streptozotocin (35 mg/kg) to induce experimental diabetes. After inducing diabetes, the animals were divided into 4 experimental groups (n = 10): diabetic control (C); resistance training (RT); aerobic training (AT); and combined training (CT). The groups were exercised for 12 weeks, 3 times/week, where: RT means the stair climbing protocol until exhaustion; AT is the 30 min/day reaching 20 m/min protocol, and CT is the combination of RT and AT. The AT group showed reduced retroperitoneal and mesenteric adipose tissue and abdominal fat deposits. Our study also showed a possible control of blood glucose, as well as decreased Interleukin 6 (IL-6) and C-reactive protein, increased circulating adiponectin and increased omentin in visceral adipose tissue. In addition, the AT group affected the glucose pathway by stimulating phosphorylation of Akt in muscle tissue. Omentin also showed a strong positive correlation with adiponectin and a moderate negative correlation with IL-6. Thus, our findings indicated that omentin in type 2 diabetes is changed by AT. Furthermore, increased omentin levels had a close association with the glucose pathway by stimulating phosphorylation of Akt in muscle tissue and with IL-6 in serum, suggesting that omentin is likely to have anti-inflammatory and protective action in experimental diabetes.

Investigations suggest the benefits of low-level laser therapy (LLLT) to improve noninvasive body contouring treatments, inflammation, insulin resistance and to reduce body fat. However, the mechanism for such potential effects in association with exercise training (ET) and possible implications in browning adiposity processes remains unclear. Forty-nine obese women were involved, aged between 20 and 40 years with a body mass index (BMI) of 30–40 kg/m2. The volunteers were divided into Phototherapy (808 nm) and SHAM groups. Interventions consisted of exercise training and phototherapy applications post exercise for 4 months, with three sessions/week. Body composition, lipid profile, insulin resistance, atrial natriuretic peptide (ANP), WNT5 signaling, interleukin-6 (IL-6), and fibroblast growth factor-21 (FGF-21) were measured. Improvements in body mass, BMI, body fat mass, lean mass, visceral fat, waist circumference, insulin, HOMA-IR, total cholesterol, LDL-cholesterol, triglycerides, and ANP in both groups were demonstrated. Only the Phototherapy group showed a reduction in interleukin-6 and an increase in WNT5 signaling. In addition, it was possible to observe a higher magnitude change for the fat mass, insulin, HOMA-IR, and FGF-21 variables in the Phototherapy group. In the present investigation, it was demonstrated that exercise training associated with LLLT promotes an improvement in body composition and inflammatory processes as previously demonstrated. The Phototherapy group especially presented positive modifications of WNT5 signaling, FGF-21, and ANP, possible biomarkers associated with browning adiposity processes. This suggests that this kind of intervention promotes results applicable in clinical practice to control obesity and related comorbidities.

Several experimental models of dietary manipulation have been created for the purpose of investigating chronic-degenerative diseases. In general, such models allow for the assessment of the qualitative and quantitative alterations of nutrients and substances contained in a food regimen. Recent studies have made use of alternative forms of dietary manipulation that have resulted in the experimental development of diseases such as diabetes, dyslipidemia, and obesity (Duarte et al. 2003; Estadella et al. 2004; Manzoni et al. 2005; Cheik 2005; Guerra 2005).

The aim of this study was to determine the effects of successive cycles of a moderately restrictive diet and refeeding with a high-fat diet on the metabolism of the adipose and hepatic tissues of obese rats. Rats were assigned to the following groups: a chow diet; a high-fat diet; a moderate caloric restriction; or a moderate caloric restriction plus refeeding. Some animals in each group were given [1-(14)C]triolein intragastrically, while others received an intraperitoneal injection of 3 mCi (3)H(2)O. All animals were killed by decapitation. The retroperitoneal, visceral epididymal and omental white adipose tissues, brown adipose tissue, liver and blood were immediately removed. The lipid uptake from the diet, in vivo rate of lipogenesis, percentage of fat, lipid profile and leptin concentration were analysed. The high-fat diet promoted an increase in fatty liver (P ≤ 0.05), adiposity mass (P ≤ 0.05) and the plasma concentration of leptin (P ≤ 0.05) and a decreased lipid uptake in white adipose tissue depots (P ≤ 0.05) in relation to the chow diet. The moderate caloric restriction did not reverse the changes promoted by the high-fat diet but induced a small decrease in adiposity, which was reversed after refeeding, and the animals maintained a dyslipidaemic profile and high fat deposition in the liver. We can conclude that the high-fat diet and subsequent moderate caloric restriction plus refeeding increased the risks of developing visceral obesity, dyslipidaemia and non-alcoholic fatty liver disease, which suggests that this type of experimental protocol can be used to study mechanisms related to the metabolic syndrome.

OBJETIVO: Investigar os efeitos do exercício de natação intermitente em relação ao exercício contínuo e ao sedentarismo, em ratos Wistar, após o desenvolvimento de obesidade exógena pela administração de uma dieta hiperlipídica palatável sobre: evolução do peso corporal, ingestão alimentar, adiposidade, percentual de gordura dos tecidos e perfil lipídico. MÉTODOS: Foram utilizados ratos adultos, mantidos em gaiolas individuais, com livre acesso a água e comida. O protocolo experimental incluiu: 1) desenvolvimento da obesidade exógena (3 semanas), os animais foram divididos em: P: sedentários alimentados com dieta padrão Primor® (n=8) e H: sedentários alimentados com dieta hiperlipídica (n=32); 2) tratamentos (8 semanas subseqüentes), os animais (n=24) passaram a receber dieta padrão e foram divididos em: sedentário; treinado contínuo e treinado intermitente. Treinamentos (5x semana): Contínuo (90 minutos/dia) e Intermitente (3x30min/dia). Os animais foram submetidos à eutanásia (3 e 8 semanas), sendo coletados os tecidos adiposos, o fígado e o sangue. Foram determinados a adiposidade e o percentual de gordura dos tecidos adiposos e do fígado, o ganho de peso corporal, o consumo alimentar e o perfil lipídico. RESULTADOS: A dieta hiperlipídica aumentou a adiposidade, o percentual de gordura acumulada no fígado e desenvolveu dislipidemias. A troca de dieta e os dois tipos de treinamento foram capazes de reverter o quadro de obesidade exógena. Contudo, o exercício intermitente foi mais eficiente na redução da adiposidade e de ganho de peso. CONCLUSÃO: Associados à dieta balanceada, os treinamentos aplicados neste estudo poderiam ser utilizados como estratégia no controle de peso e de dislipidemias, tanto em modelos experimentais quanto em seres humanos.

Objective: This study aimed to examine and compare the effects of continuous or intermittent exercises on adiposity and fatty liver in rats fed with high-fat diet. Methods and Procedures: Wistar rats were divided according to diet composition—chow diet (C) or high-fat diet (H)—and kinds of exercise—sedentary (S), continuous (CE), or intermittent (IE) exercises. The CE group swam 90 min/day, and the IE group swam 3 × 30 min/day (at 4-h intervals between sessions); both groups exercised 5 days/week during 8 weeks. Body weight and food intake were recorded daily. Lipogenesis rate in vivo was determined by the incorporation of 3H2O into saponified lipids in retroperitoneal (RET), epididymal (EPI), and visceral (VIS) white adipose tissues, brown adipose tissue (BAT), liver (L), and gastrocnemius muscle (GAST) using the gravimetric method. Total cholesterol, high-density lipoprotein (HDL)-cholesterol, and triacylglycerol (TG) were analyzed. Results: The major finding of this study is that IE was more efficient than CE in reducing the adverse effects of high-fat diet and sedentarism. There was an improvement in the lipid profile and a reduction in food intake, body weight gain, visceral and central adiposity, and fatty liver, contributing to the control of obesity and other comorbidities, including nonalcoholic fat liver diseases. Discussion: Earlier studies have discussed the effects of diet consumption on adiposity and their relation to chronic diseases and obesity. This study discusses the effects of high-fat diet consumption and the different kinds of exercise on weight gain, adiposity, fatty liver, and lipid profile in rats. The results may depend on the exercise, time of each session, age, gender, and experimental period.

Objective We investigated the effects of severe caloric restriction and refeeding with a high-fat diet on lipid uptake by visceral adipose fat and lipid profile in rats. Methods Rats were assigned to six groups: a chow diet (C), a high-fat diet (H), severe caloric restriction (SC and SH), and severe caloric restriction plus refeeding (SC-r and SH-r) during 8 wk. All animals were killed by decapitation 4 h after intragastric administration of [1-14C] triolein (∼0.5 g, 0.3 μCi/rat). Liver; visceral retroperitoneal (RET), epididymal (EPI), and omental (VIS) white adipose tissues; brown adipose tissue; and intestine were immediately removed and weighed. The whole intestine was withdrawn and homogenized to determine lipid uptake. Total cholesterol, high-density lipoprotein (HDL), and triacylglycerol in plasma were determined enzymatically. Results The SC and SH groups showed reduced visceral adiposity, although this effect was more evident in the SC group. The SC group had greater lipid absorption in the VIS than the C group. The SH treatment increased RET and VIS lipid uptake in relation to the H group. The SH-r treatment increased RET and VIS adiposity. HDL cholesterol decreased with caloric restriction in the SC and SH groups. The SH-r treatment did not increase HDL cholesterol. Conclusion Severe caloric restriction decreased visceral adiposity even in rats in the H group but did not reduce the risk of development of dyslipidemia. Therefore, food restriction plus refeeding with a high-fat diet increase the risk of development of visceral adiposity and dyslipidemia.

Introduction Obesity is one of the most important link factors to coronary artery disease development mainly due to the pro-inflammatory and pro-thrombotic states favoring atherosclerosis progression. The LLLT acts in the cellular metabolism and it is highly effective to improve inflammation. The same occur in response to different kinds of exercise. However, we have not known the associate effects using LLLT therapies with aerobic plus resistance training as strategy specifically with target at human obesity control and its comorbidities. Objective Investigate the effects of the LLLT associated with aerobic plus resistance training on cardiometabolic risk factors in obese women. Methodology Women aged 20–40 years (BMI ≥ 30 kg/m2), were divided into 2 groups: Phototherapy (PHOTO) and Placebo. They were trained aerobic plus resistance exercises (in a concurrent mode), 1 h, 3 times/week during 16 weeks. Phototherapy was applied after each exercise session for 16 min, with infrared laser, wavelength 808 nm, continuous output, power 100 mW, and energy delivery 50 J. The body composition was measured with bioimpedance. Inflammatory mark concentrations were measured using a commercially available multiplex. Results LLLT associated with aerobic plus resistance training was effective in decrease neck (P = 0.0003) and waist circumferences (P = 0.02); percentual of fat (P = 0.04); visceral fat area (P = 0.02); HOMA-IR (P = 0.0009); Leptin (P = 0.03) and ICAM (P = 0.03). Also, the reduction in leptin (P = 0.008) and ICAM-1 (0, 05) was much more expressive in the phototherapy group in comparison to placebo group when analyzed by delta values. Conclusion LLLT associated with concurrent exercise (aerobic plus resistance training) potentiates the exercise effects of decreasing the cardiometabolic risk factors in obese woman. These results suggest the LLLT associated with exercises as a new therapeutic tool in the control of obesity and its comorbidities for obese people, targeting to optimize the strategies to control the cardiometabolic risk factors in these populations.

Obesity affects approximately 20% of the world population, and exercise is the primary non-pharmacological therapy. The combined use of exercise and low-level laser therapy (LLLT) may potentiate the effects promoted by exercise. The objective of this study was to investigate the effects of exercise in combination with phototherapy on adipocyte area, activity of the enzyme citrate synthase and muscle morphological analysis. We used 64 Wistar rats, which were divided into eight groups with 8 rats each: sedentary chow-diet (SC); sedentary chow-diet plus laser therapy (SCL), exercised chow-diet (EC); exercised chow-diet plus laser therapy (ECL); sedentary high-fat diet (SH); sedentary high-fat diet plus laser therapy (SHL); exercised high-fat diet (EH); exercised high-fat diet, laser therapy (EHL). The animals were submitted to a program of swimming training for 90 min/5 times per week for 8 weeks and LLLT (GA-Al-AS, 830 nm) at a dose of 4.7 J/point and a total energy of 9.4 J/animal, with duration of 47 s, which was applied to both gastrocnemius muscles after exercise. We conclude that the combined use of exercise and phototherapy increases the activity of the enzyme citrate synthase and decreases the white adipocyte area epididymal, retroperitoneal and visceral in obese rats, enhancing the effects of exercise.

Obesity and associated dyslipidemia is the fastest growing health problem throughout the world. The combination of exercise and low-level laser therapy (LLLT) could be a new approach to the treatment of obesity and associated disease. In this work, the effects of LLLT associated with exercises on the lipid metabolism in regular and high-fat diet rats were verified. We used 64 rats divided in eight groups with eight rats each, designed: SC, sedentary chow diet; SCL, sedentary chow diet laser, TC, trained chow diet; TCL, trained chow diet laser; SH, sedentary high-fat diet; SHL, sedentary high-fat diet laser; TH, trained high-fat diet; and THL, trained high-fat diet laser. The exercise used was swimming during 8 weeks/90 min daily and LLLT (GA-Al-As, 830 nm) dose of 4.7 J/point and total energy 9.4 J per animal, applied to both gastrocnemius muscles after exercise. We analyzed biochemical parameters, percentage of fat, hepatic and muscular glycogen and relative mass of tissue, and weight percentage gain. The statistical test used was ANOVA, with post hoc Tukey–Kramer for multiple analysis between groups, and the significant level was p

The combination of exercise and high-fat diet promotes related effects on lipid metabolism, but opposite effects on the carbohydrate metabolism. The mechanisms of action of LLLT could alter these correlations for the carbohydrate metabolism.

The use of laser and ultrasound shows promising results as non-pharmacological pain treatment. This study evaluated the effects of laser and ultrasound on abdominal pain in mice.
