Abstract
Endocrine physiology is a complex subject for students. Game-based learning (GBL) and case-based learning (CBL) are active methodologies that are widely used because of their potential for motivation and greater proximity to the reality of modern students. We evaluated the effectiveness of GBL and CBL among veterinary medicine students compared with a control group using peer tutoring. Students (n = 106) from two institutions volunteered to participate in this study. The participants were submitted to a pretest questionnaire and subsequently were divided into three paired groups by their performance on the pretest exam: 1) traditional class + peer tutoring, 2) traditional class + GBL, and 3) traditional class + CBL. After the students completed the activities, their performance was once again evaluated by applying a new test with the same initial 10 questions and another set of 10 different questions. The students' perceptions and satisfaction with the methodologies and learning strategies were assessed. Anxiety was assessed with the State-Trait Anxiety Inventory before and after the conventional class and after the active methodologies. The GBL group significantly improved their correct answers compared with the baseline (P < 0.05), with no significant difference from CBL and peer tutoring. Anxiety levels did not differ regardless of the time of evaluation or the teaching methodology applied. GBL promoted a greater perception of the stimulus for self-study and problem-solving ability and contributed to the development of group dynamics compared with the group who received CBL (P < 0.05). In conclusion, GBL showed better results than peer tutoring and CBL.NEW & NOTEWORTHY We compared the supplementary use of game-based learning, case-based learning, and peer tutoring in the study of endocrine physiology by veterinary students and observed a slight advantage for game-based learning over the other two methodologies. The game was developed by the authors and is an unprecedented tool that can prove useful to improve knowledge acquisition in students of veterinary medicine. Thus, game-based learning is an effective supplementary teaching strategy.

Abstract
AIMS We sought to analyze the impacts of social restriction measures imposed by the pandemic COVID-19 on the control of metabolic parameters in diabetic patients. METHODS We accessed the medical records of patients who underwent clinical follow-up in the public and private health systems between July 2019 and June 2021. The sample consisted of 288 patients (111 adults and 177 older individuals). A two-way ANOVA mixed model was used to test the effects of intra- (time: baseline and after 24 months) and inter-subject factors. Linear regression analysis was used to predict the difference in body weight considering age, sex, HbA1c, health care system and insulin use. RESULTS Among adults, we observed an increase in body weight and LDL-c levels, especially for insulin users (p ≤ 0.05). Adults assisted by the public health care system showed higher HbA1c levels (p = 0.001). Among older individuals using insulin, blood glucose levels decreased (p = 0.019). Body weight decreased in those assisted by the private system (p = 0.005), while glycemia decreased for patients assisted by both health care systems (p = 0.043). The linear regression model confirmed that the increase in body weight was more pronounced in adults than in older individuals. CONCLUSION The social restriction measures imposed by the pandemic affected the metabolic control of diabetic patients, especially adults assisted by the public health care system.

Abstract
The suspension of social activities combined with health insecurity, uncertainty and fear of COVID-19 may influence physical activity practice. We aimed to investigate the relationship between the fear of COVID-19 and anxiety on physical activity patterns during the pandemic period. This cross-sectional study was performed in a sample of 520 Brazilian participants recruited by online sampling and snowball method. We assessed demographic variables, health perceptions, anxiety, fear of COVID-19 and physical activity characteristics. Both fear scores and anxiety were higher in woman (p < 0.0001). We observed a remarkable reduction in the frequency and intensity of physical activity and a modification in the exercise practice environment (from gym or sports centers to home-based physical activity) (p < 0.05). Sedentary (sitting) behavior increased during pandemic both in the weekdays and in the weekend (p < 0.0001). Participants who have never been infected were more prone of being classified in higher levels for physical activity (OR: 1.916, CI = 1.043-3.521) versus those who were previously infected (p = 0.05). Participants with a low or moderate level of physical activity before the pandemic presented lower chances of being classified as high physical activity level during the pandemic in comparison to those with high level before pandemic (p < 0.001). The Fear of Covid-19 score was negatively associated with the physical activity level (the higher the fear, the lower the level of physical activity); that is, for every increase in scale score, the odds of vigorous physical activity decreased 3%. In conclusion, fear of COVID-19 and previous contact with the virus negatively influenced physical activity practice.

Abstract
Selenium (Se) is an essential micronutrient known to play an important role in the antioxidant system that can potentially influence tumor growth. We aimed to investigate the effects of dietary Se supplementation after detection of 4T1 mammary tumor growth in BALB/c mice. Thirty female mice received subcutaneous inoculation of 4T1 cells. After five days, all animals presenting palpable tumors were randomly assigned to three groups: a control group (Se-control) receiving a diet with adequate Se (0.15 mg/kg) and two other groups that received Se-supplemented diets (1.4 mg/kg of total Se) with either Brazilian nuts (Se-Nuts) or selenomethionine (SeMet). Data were assessed by either One or Two-way ANOVA followed by Tukey's HSD or Bonferroni's post hoc tests, respectively. Both Se-supplemented diets reduced tumor volume from the thirteenth day of feeding compared with the Se-adequate (control) diet (p < 0.05). The SeMet group presented a higher Se blood concentration (p < 0.05) than the Se-control group, with the Se-Nuts group presenting intermediate values. Selenoprotein P gene expression in the liver was higher in the Se-Nuts group than in the Se-control group (p < 0.05), while the SeMet group presented intermediate expression. Dietary Se supplementation, starting after detection of 4T1 palpable lesions, reduced tumor volume in mice.

Abstract
BACKGROUND Candlenut (CN) has been used indiscriminately for weight loss. In vivo effects of CN in different doses are scarce. OBJECTIVE To evaluate the effects of CN ingestion in obese rats. DESIGN Thirty animals (obese and non-obese) received one of three different types of treatments: placebo, CN ingestion in a popular therapeutic regimen (8 days with oral administration of 0.2 mg/kg followed by 20 days with doses of 0.4 mg/kg), and ingestion of a doubled popular dose-called 2CN. Treatment was maintained for 28 days. RESULTS The fatty acid profile of CN indicated mainly linolelaidic and palmitoleic acids. Rats receiving CN and 2CN showed reduced plasmatic levels of glucose and lipoproteins (p < 0.05). A dose-dependent carcass fat reduction was observed (p < 0.05). Blood levels of aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) reduced with CN and increased with 2CN doses (p < 0.05). Alanine aminotransferase (ALT) and the atherogenic index remained similar among all treatments (p > 0.05). Hepatic vacuolation decreased with CN, but the 2CN dose produced mononuclear leucocyte infiltrate. CONCLUSIONS Although CN presented beneficial effects on the metabolism of rats, it also caused increased risk of liver damage.

Abstract
We investigated the fear of COVID-19 infection after proper translation and cultural adaptation of the "Fear of COVID-19 Scale" to the Brazilian Portuguese language. A sample of 1,743 Brazilian participants were included. The scale showed excellent psychometric characteristics. Women showed higher anxiety levels. Fear of COVID-19 scores were lower in males with occupational risk of contamination. On the other hand, women and younger individuals showed higher fear of COVID-19 infection scores. The Brazilian Fear of COVID-19 Scale proved to be a reliable tool with excellent psychometric properties for identifying fear of COVID-19 infection in the Brazilian population.

Abstract
BACKGROUND Periodontal disease is one of the most frequent comorbidities in diabetic patients and can contribute to poor blood glucose control. OBJECTIVE To evaluate the effects of ingesting different doses of beta-glucans (BG) isolated from Saccharomyces cerevisiae on alveolar bone loss (ABL) and inflammatory/metabolic parameters in normal and diabetic rats with ligature-induced periodontal disease (PD). DESIGN Sixty male rats were assigned into two groups: non-diabetic or diabetic (i.p. 70 mg/kg streptozotocin) with PD. Then, groups were subdivided into five subgroups according BG doses: 0 mg/Kg; 10 mg/Kg; 20 mg/Kg; 40 mg/Kg or 80 mg/Kg. Animals received BG for 28 days and ligatures were placed on lower first molars during the last 14 days. RESULTS ABL of diabetic and non-diabetic animals receiving BG 40 mg/kg (1.33 ± 0.03 mm and 0.77 ± 0.07 mm, respectively) and 80 mg/kg (1.26 ± 0.07 mm and 0.78 ± 0.05 mm, respectively) doses was lower (p < 0.05) in comparison to respective controls (1.59 ± 0.11 mm and 0.90 mm ±0.08). COX-2 (Control: 1.66 ± 0.12; 40 mg/kg: 1.13 ± 0.07; 80 mg/kg: 0.92 ± 0.18) and RANKL expressions (Control: 1.74 ± 0.34; 40 mg/kg: 1.03 ± 0.29 ;80 mg/kg: 0.75 ± 0.21), together with the RANKL/OPG ratio (Control: 1.17 ± 0.08; 40 mg/kg: 0.67 ± 0.09; 80 mg/kg: 0.63 ± 0.28) were attenuated above the same dose (p < 0.05). BG did not influence (p > 0.05) metabolic parameters in non-diabetic rats. In diabetic animals, doses above 40 mg/kg reduced IL-1β (Control: 387 ± 66; 40 mg/kg: 309 ± 27; 80 mg/kg: 300 ± 14) and TNF-α (Control: 229 ± 19; 40 mg/kg: 128 ± 53; 80 mg/kg: 71 ± 25), blood glucose levels (Control: 402 ± 49; 40 mg/kg: 334 ± 32; 80 mg/kg: 287 ± 56), total cholesterol (Control: 124 ± 8; 40 mg/kg: 120 ± 10; 80 mg/kg: 108 ± 9), LDL-c + VLDL-c (Control: 106 ± 8; 40 mg/kg: 103 ± 10; 80 mg/kg: 87 ± 10) and triacylglycerols (Control: 508 ± 90; 40 mg/kg: 301 ± 40; 80 mg/kg: 208 ± 61), whereas increased HDL-c (Control: 18 ± 0.5; 40 mg/kg: 19 ± 1; 80 mg/kg: 21 ± 1) (p < 0.05). Optimal dose needed to reduce ABL was higher in diabetic animals with PD. CONCLUSIONS BG ingestion reduced ABL and improved inflammatory profile in a dose-dependent manner. Best effects were achieved with doses above 40 mg/kg.

Abstract
Modern lifestyle and social demands induce changes in sleep routines that may not meet individual circadian preferences (chronotype). Such changes may be associated with the development of unhealthy lifestyles and the emergence of diseases relevant to public health services, such as obesity, hypertension, and diabetes mellitus, as well as sleep bruxism (SB) and awake bruxism (AB). The present study aimed to assess the relationship between the evening, morning or intermediate chronotypes with the report of possible SB and AB in adult individuals assisted by the Family Health Strategy (FHS). The selection of participants was performed through probabilistic cluster analysis. The sample size (n = 384) was calculated to include a representative sample of the 52,628 adults registered in the FHS of a countryside city located in the Southeast Region of Brazil. The Morningness-Eveningness Questionnaire (MEQ) was used to determine the chronotype, and Questionnaire-Based Self-Reported Bruxism was used for identifying possible SB and AB. The following clinical and social-behavioral variables were also evaluated: age, sex, BMI, income, physical activity, schooling, alcohol consumption and smoking, chronic diseases and depression. Two logistic regression models were used: one for SB and one for AB. Possible SB was associated with female sex, lack of physical activity and income above 2 minimum wages. Regarding chronotype, a 19% reduction in the chance of possible SB was observed in morning individuals compared to evening individuals (p = .017). Possible AB was associated with younger individuals, smoking and depression. In conclusion, compared with the evening circadian preference, the morning circadian preference was associated with greater protection against possible SB in an adult population assisted by the FHS.

Abstract
The COVID-19 pandemic caused several changes in the teaching-learning process, as it abruptly replaced the conventional classes into online classes despite social distancing requirements. Such changes may be associated with several mental health problems and negatively affect the quality of life and academic performance of university students. We performed a cluster analysis in a large sample of Brazilian undergraduate students, considering sociodemographic data, physical activity frequency, study areas, Burnout Syndrome (BS), Quality of Life (QoL) and perception of online learning (OL) during COVID-19 pandemic. Seven hundred and three students (between 17 and 62 years, from 67 higher education institutions) participated in the study. We identified three different profiles of students regarding psychological aspects and OL perception. The first profile, called as the 'Low QoL' group was composed of younger students, mainly females, with higher frequency of psychological disorders (as evidenced by the self-report of depression and/or anxiety), in addition to higher Burnout scores, lower QoL and worse OL perception. The second profile called 'Intermediate QoL' comprised participants with an average age of 45 years, with a greater number of men, married, with kids and working in addition to studying. They presented better OL scores than the 'Low QoL' group. The third profile called 'Better QoL' comprised students with higher scores in all domains of QoL and better OL perception, with greater frequency of physical activity and lower BS scores. Students from Health courses showed higher scores for general QoL, and also for the psychological and environmental domains in relation to the other areas. Besides, students of the Exact Sciences courses showed higher scores on all OL perception items in comparison to the other courses. Our results provide insights regarding the mental health profile of undergraduate students, allowing educational managers to outline specific coping strategies to assist students during the pandemic.

Abstract
We aimed to validate a Brazilian Portuguese version of the Obsession with COVID-19 Scale (BP-OCS) using a large sample of university students in Brazil (N = 1454). The scale showed solid psychometric characteristics in terms of internal consistency (α = .78), test-retest reliability (ICC = .86), factorial validity (PAF and CFA support), and construct validity. Additionally, BP-OCS scores were found to be higher among females, participants with diagnosed depression, anxiety, and self-reported anxiety. These findings suggest that the BP-OCS is a reliable and valid measure of persistent and disturbed thinking about COVID-19 for Brazilian university students.

Abstract
Resveratrol is an anti-inflammatory compound found in several foods. Periodontal disease (PD) is associated to other systemic diseases, and inflammation may be responsible for the association. Consequently, controlling inflammation not only may benefit oral health but also may assist with the management of other chronic inflammatory conditions. We aimed to investigate the effects of resveratrol administration on PD control in preclinical studies. A systematic search was performed for scientific articles using both electronic databases and a manual search using combinations of the following keywords: “resveratrol” OR “3,5,4′-trihydroxystilbene” AND “periodontal disease” OR “periodontitis” OR “gingivitis”. Only in vivo original studies investigating resveratrol treatment on experimental animal models of PD were selected. A quality assessment of the studies was performed using the Animal Research Reporting In Vivo Experiment (ARRIVE) guidelines, and the risk of bias was assessed using the Syrcle tool. The search returned 570 articles, and 11 matched the inclusion criteria. A meta-analysis showed that resveratrol treatment attenuated alveolar bone loss (τ2 = 0.0041; 95% CI: −0.14; −0.04). The ARRIVE criteria reported a good quality of studies in general (mean score 28.5 ± 2.5). However, five Syrcle domains indicated a high risk of bias or did not present information clearly. We concluded that, in preclinical studies, resveratrol treatment prevented PD progression.

Abstract
INTRODUCTION Diabetes mellitus is a metabolic disease characterized by high glycemic levels for long periods. This disease has a high prevalence in the world population, being currently observed an increase in its incidence. This fact is mainly due to the sedentary lifestyle and hypercaloric diets. Non-pharmacological interventions for glycemic control include exercise, which promotes changes in skeletal muscle and adipocytes. Thus, increased glucose uptake by skeletal muscle and decreased insulin resistance through modulating adipocytes are the main factors that improve glycemic control against diabetes. CONCLUSION It was sought to elucidate mechanisms involved in the improvement of glycemic control in diabetics in front of the exercise.

Abstract
This study evaluated the effect of the consumption of different levels and sources of lipids on metabolic parameters of Wistar rats. Animals were fed with high-fat diet (HFD) containing 20% of lard for 12 weeks to cause metabolic obesity. Subsequently, the animals were divided into six groups and were fed diets with lipid concentrations of 5% or 20% of lard (LD), soybean oil (SO) or fish oil (FO), for 4 weeks. Data were submitted to analysis of variance (two-way) followed by Tukey post hoc test (p < 0.05). The groups that consumed FO showed less weight gain and lower serum levels of triacylglycerol (TAG), total cholesterol and fractions, aspartate aminotransferase (AST) activity, atherogenic index, less amount of fat in the carcass, decreased Lee index and lower total leukocyte counting (p < 0.05). These same parameters were higher in LD treatment (p < 0.05). In the concentration of 20%, carcass fat content, blood glucose levels, as well as alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) decreased in FO groups (p < 0.05). The SO group had intermediate results regarding the other two treatments (FO and LD). We concluded that fish oil intake was able to modulate positively the metabolic changes resulting from HFD.

Abstract
Physical activity and the ingestion of dietary fiber are non-drug alternatives commonly used as adjuvants to glycemic control in diabetic individuals. Among these fibers, we can highlight beta-glucans. However, few studies have compared isolated and synergic effects of physical exercise and beta-glucan ingestion, especially in type 2 diabetic rats. Therefore, we evaluated the effects beta-glucan (Saccharomyces cerevisiae) consumption, associated or not to exercise, on metabolic parameters of diabetic Wistar rats. The diabetes mellitus (DM) was induced by high-fat diet (HFD) associated with a low dose of streptozotocin (STZ-35 mg/kg). Trained groups were submitted to eight weeks of exercise in aquatic environment. In the last 28 days of experiment, animals received 30 mg/kg/day of beta-glucan by gavage. Isolated use of beta-glucan decreased glucose levels in fasting, Glycated hemoglobin (HbA1c), triglycerides (TAG), total cholesterol (TC), low-density lipoprotein (LDL-C), the atherogenic index of plasma. Exercise alone also decreased blood glucose levels, HbA1c, and renal lesions. An additive effect for reducing the atherogenic index of plasma and renal lesions was observed when both treatments were combined. It was concluded that both beta-glucan and exercise improved metabolic parameters in type 2 (HFD/STZ) diabetic rats.

Abstract
The relationship between type 2 diabetes oral physiology, nutritional intake and quality of life has not been fully elucidated. We assessed the impact of type 2 diabetes - exclusive or associated with hypertension with beta-blockers treatment - on oral physiology, mastication, nutrition and quality of life. This cross-sectional study was performed with 78 complete dentate subjects (15 natural teeth and six masticatory units minimum; without removable or fixed prostheses), divided into three groups: diabetics (DM) (n = 20; 45·4 ± 9·5 years), diabetics with hypertension and receiving beta-blockers treatment (DMH) (n = 19; 41·1 ± 5·1 years) and controls (n = 39; 44·5 ± 11·7 years) matched for gender, age and socioeconomic status. Blood glucose, masticatory performance, swallowing threshold, taste, food intake, stimulated and unstimulated salivary flow, pH and buffering capacity of saliva were assessed. Glycemia was higher in DM than in controls (P < 0·01). No differences were observed between DM and controls for nutrition and quality of life. Both stimulated and unstimulated salivary flow rate were lower in DMH (P < 0·01), which also presented the lowest number of teeth and masticatory units (P < 0·0001), and reduction in the number of chewing cycles (P < 0·01). Controls showed lower Decayed Missing Filled Teeth index (DMFT) scores in comparison with DMH (P = 0·021). Masticatory performance and saliva buffering capacity were similar among groups. Exclusive type 2 diabetes did not alter oral physiology, nutrition or quality of life. However, when hypertension and beta-blockers treatment were associated with diabetes, the salivary flow rate, chewing cycles and number of teeth decreased.

Abstract
We evaluated training adaptation and physical performance parameters in rats orally supplemented with glycerol, glucose, or saline, and submitted to moderate aerobic exercise. Thirty male rats were trained for 6 weeks and administered the supplements during the last 4 weeks of the experiment. Animals were distributed in a completely randomized factorial 2 × 3 design (with or without exercise and 3 substrates). Data were subjected to analysis of variance (ANOVA) and means were compared using the Student-Newmann-Keuls test at 5%. Among the trained animals, none of the substances caused differences in the percentages of protein, fat, or water content in the carcass. Compared with the sedentary animals, the trained animals supplemented with saline and glucose showed a higher protein percentage in the carcass. The relative mass of the heart and adrenal glands was higher in the trained animals. Glycerol improved the protein content in non-trained animals and increased the relative adrenal mass in both groups. Glycerol reduced the variation in levels of lactate and aspartate aminotransferase (AST) during the last exercise session. There was no difference between groups regarding the relative mass of the thymus and gastrocnemius or with the diameter of muscle fibers or the neutrophil-lymphocyte ratio. Supplementation with glycerol was efficient at attenuating variation in AST and lactate levels during exercise.

Abstract
INTRODUCTION beta-glucans (BG) derived from plant tissues are reported to show metabolic effects. In contrast, those fibers isolated from yeast seem to be more related to immune response modulation. Since diabetic individuals are more susceptible to exacerbation of inflammatory signs, the ingestion of fibers that could conjugate both metabolic and immune effects would be of great importance. OBJECTIVE we investigated the effect of BG - Saccharomyses cerevisae - ingestion on glycemic and lipoprotein profile of diabetic rats. DESIGN twenty-four adult Wistar rats were used, distributed into 4 groups in a design of entirely casualized delineation with a 2 x 2 factorial model (with and without diabetes; with and without BG). Diabetes Mellitus was induced by an intraperitoneal injection of 80mg/kg of strepzotocin. Thus, animals with fasting glycemia of over 250 mg/dl were considered diabetic. Forty-eight hours after induction, the rats received daily doses of 30 mg/kg of BG or saline solution by gavage during 28 days. RESULTS AND DISCUSSION the Groups with DM presented a higher glycemic index and lower C peptide levels than the control groups, in addition to lower weight gain and higher ration consumption, water ingestion and urinary volume. Total cholesterol levels (CT), LDL-C + VLDL-C, plasma triacylglycerides (TAG) and alanine aminotransferase (ALT) were also higher in the diabetic animals (p < 0.05), and there were no alterations in the HDL-C levels. The ingestion of BG reduced blood glucose concentrations (30%), TAG (32%) and ALT (41%) (p < 0.05). No histopathological hepatic alterations were observed in any of the groups. Furthermore, the diabetic animals present increase in villous:crypt ratio (V:C) in the duodenum, without interference of BG. No alterations in the carcass were observed between the groups. CONCLUSION it was concluded that the use of BG significantly reduced the glycemic, TAG and ALT levels, showing its therapeutic potential.

Abstract
INTRODUCTION Cancer treatment can affect the health of the teeth and support structures, which are essential to the chewing process, which may change the nutritional status of the patient. OBJECTIVE The aim of this study was to evaluate the impact of oral physiology changes on quality of life (QoL) of patients submitted to cancer treatment. DESIGN Initially 84 cancer patients were screened and only those presenting at least 15 natural teeth were selected for oral physiology and quality of life tests. The final sample comprised 30 patients. Twenty subjects were selected as controls paired by age and gender. Dental caries status, salivary flow, masticatory performance (MP), location of tumor, duration of chemo and radiotherapy and World Health Organization Quality of Life (WHOQOL- bref) questionnaire were assessed. Linear regression models were used to test the relationship between the WHOQOL-bref domains (physical, psychological, social relationship, environmental and overall QoL) and independent variables under study. RESULTS AND DISCUSSION Number of teeth, MP and salivary flow were lower in cancer patients, as well as for the scores obtained in Social Relationship, Environment and Overall QoL domains (p<0.050). Breast cancer caused a negative impact on Psychological (p<0.001) and Overall QoL scores (p=0.017). A similar negative effect was found for the duration of radiotherapy on Psychological (p=0.012) and Environmental (p=0.039) domains. On the other hand, the maintenance of teeth had a positive impact on Psychological (p=0.012) and Environmental (p=0.024) scores. CONCLUSION Oral physiology changes may impact the QoL of oncological patients. The maintenance of teeth was of positive importance, especially for the psychological aspects.

We show that a small number of intentionally introduced defects can be used as a spectroscopic tool to amplify quasiparticle interference in 2H-NbSe2 that we measure by scanning tunneling spectroscopic imaging. We show, from the momentum and energy dependence of the quasiparticle interference, that Fermi surface nesting is inconsequential to charge density wave formation in 2H-NbSe2. We demonstrate that, by combining quasiparticle interference data with additional knowledge of the quasiparticle band structure from angle resolved photoemission measurements, one can extract the wave vector and energy dependence of the important electronic scattering processes thereby obtaining direct information both about the fermiology and the interactions. In 2H-NbSe2, we use this combination to confirm that the important near-Fermi-surface electronic physics is dominated by the coupling of the quasiparticles to soft mode phonons at a wave vector different from the charge density wave ordering wave vector.

Abstract
We evaluated the effects of oral glycerol supplementation on trained rats fed a normal diet. Wistar rats were distributed among 6 groups in a completely randomized 2 × 3 factorial design. The animals were subjected to 6 weeks of aerobic training. In the last 4 weeks, the animals’ diet was supplemented with saline, glucose, or glycerol. Data were subjected to one-way analysis of variance (ANOVA) followed by a Student–Newmann–Keuls test, with values for P < 0.05 considered statistically significant. The change in body mass was lower in the trained groups, and their food and water consumption were higher. Glycerol supplementation resulted in an increase in the levels of triacylglycerol (TAG) and total cholesterol, as well as in the area and diameter of adipocytes. When associated with training, these parameters were similar to those of other trained groups. Levels of low-density lipoprotein + very-low-density lipoprotein cholesterol decreased in the trained animals that received glycerol compared with the non-trained ones. Glycerol consumption caused a reduction in food intake and increased the villous:crypt (V:C) ratio. No changes in glycemia, high density lipoproteins, or density of adipocytes were observed. Supplementation with glycerol together with aerobic physical training promoted beneficial metabolic effects. However, in non-trained rats glycerol increased the diameter and area of adipocytes, as well as the levels of TAG and total cholesterol.

Abstract
The use of glycerol in the diets for animals is of interest because it is a residue of biodiesel production and rich in energy. Thus, this study aimed to evaluate metabolic and physiological parameters of rats receiving supplemental pure glycerol by gavage. We used 30 Wistar rats (initial weight 202.7 ± 29.98 g) receiving 0 (control/saline), 200, 400, 800 and 1600 mg glycerol/kg of body weight (bidistilled glycerine, 99.85% glycerol) beside food and water ad libitum for 28 days. We used a completely randomised design with five treatments and six replicates. At the end of the experiment, the animals were killed, and the results showed that there was no change (p > 0.05) in the intake and excretion of water, the average daily weight gain, dry matter, ash and crude protein in the carcass or plasma triacylglycerols. There was a beneficial effect (p < 0.05) up to a dose of 800 mg/kg glycerol on feed intake, percentage of carcass fat, plasma levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), high-density lipoprotein (HDLc) and low-/very low-density lipoprotein (LDLc + VLDLc). The levels of total cholesterol and glucose were increased with up to a dose of 800 mg/kg glycerol (but remained within the normal range); they were reduced with the dose of 1600 mg/kg. The total leucocyte count tended to be reduced, although it was within the reference values for rats. There were no renal or pancreatic lesions. In conclusion, glycerol presented as a safe supplement at the studied doses, even having some beneficial effects in a dose-dependent manner in rats.

Abstract
INTRODUCTION Functional foods have been widely utilized to reduce the symptoms of various diseases such as diabetes mellitus (DM). Among the foods used to combat these effects are soluble fibres, mainly those rich in beta- glucans (BGs). OBJECTIVE To review the effects of beta-glucans (BGs) on glucose plasmatic levels of diabetic individuals. DESIGN A search was conducted using the Pubmed, Science Direct and Scielo databases using the keywords: diabetes mellitus and beta-glucan and glucose and glycaemia. As inclusion criteria, only studies on diabetic human individuals (type 1 or type 2) who consumed BGs were selected. RESULTS AND DISCUSSION Of the 819 initial articles retrieved, only 10 fit the inclusion criteria and were used in the study. It was observed that doses around 6.0g/person/ day, for at least 4 weeks were sufficient to provoke improvements in the blood glucose levels and also lipid parameters of individuals with DM. However, glucose levels do not reach normal levels using BG alone. Low doses of BG for at least 12 weeks were also reported to promote metabolic benefits. CONCLUSIONS Based on previous research, it was concluded that the ingestion of BGs was efficient in decreasing glucose levels of diabetic patients. The consumption of greater doses or smaller doses for longer periods of time produced better results.

Abstract
Os objetivos desse estudo quali-quantitativo foram verificar as experiências subjetivas relacionadas ao exercício em idosas antes e depois da realização de atividade física em ambientes real e virtual, bem como a preferência pelo ambiente. A amostra foi composta por 20 idosas (71,1±6,5 anos) que executaram sessões de dança nos dois ambientes e responderam ao instrumento Subjective Exercise Experiences Scale (SEES) antes e depois da prática. Na situação virtual foi utilizado o jogo Just Dance I do console Wii® da Nintendo. Na situação real, cada participante reproduziu os mesmos movimentos demonstrados pela pesquisadora. Para a análise dos dados da SEES foram utilizados os testes Wilcoxon e Mann-Whitney (p<0,05). Houve redução significativa na pontuação da subescala distress psicológico da SEES após ambas as situações experimentais e aumento no bem-estar positivo apenas em ambiente virtual. A maioria das idosas escolheu o ambiente real como o preferido.

Abstract
The intracellular fate of Toxoplasma gondii was studied in primary cultures of skeletal muscle cells (SMC). The labelling of secondary lysosomes with BSA-Au particles showed no phagolysosomal fusion with the vacuole containing the parasite. After internalization of the parasites, the parasitophorous vacuole became involved by closely apposed endoplasmic reticulum (ER) and mitochondria; within 18 h of interaction, microtubules were visualized in association with the parasitophorous vacuole, suggesting that they could form a barrier for the phagolysosomal fusion.

Abstract
We compared the peripheral and pulmonary response to assess the phagocytic activity of monocytes/macrophages and neutrophils and the lymphoproliferative response (LPR) against Mycobacterium tuberculosis antigens from 21 AIDS patients, presenting at diagnosis with active pulmonary tuberculosis (TB), other non-TB pulmonary infection, or no pulmonary infection, as well as patients with active pulmonary TB and healthy control subjects. Alveolar lymphocyte analysis demonstrated that AIDS/TB patients had more markedly reduced percentages of CD4(+) lymphocytes than AIDS/TB patients and an increase in the percentage of CD8(+) lymphocytes, probably reflecting the impairment of CD4(+) T lymphocytes in peripheral blood at the lungs. Moreover, alveolar lymphocytes from AIDS/TB patients demonstrated a two- to fourfold decrease in LPR against M. tuberculosis antigens. Interestingly, it was observed an enhanced migration of natural killer cells to the lungs in all patients group. The phagocytic activity in alveolar macrophages and neutrophils showed that AIDS/TB patients had a twofold decreased capacity to ingest inert particles compared with AIDS patients. Comparing the alveolar and peripheral lymphocyte number and functional activity to M. tuberculosis-antigens it was possible to demonstrate that in both sites these cells had similar profile. However, the innate immune response in lungs showed a reduced activation in the presence of HIV infection, regarding the M. tuberculosis coinfection. These findings suggest that the advanced impairment of CD4(+) T lymphocyte in HIV-1 infection may lead to a deactivation of alveolar macrophages, enhancing bacilli burden and HIV replication in the lungs and furthering dissemination.

Abstract
PURPOSE We compared our experience with ureteroscopic stone basket manipulation under fluoroscopic guidance to ultrasound ureterolithotripsy for distal ureteral stone removal. MATERIALS AND METHODS Retrospectively, we analyzed the medical records of 981 patients with ureteral calculi between January 1994 and December 1995, of whom 483 (49%) were treated for stones in the lower ureter and constituted our study group. The decision of when to perform lithotripsy (group 2) versus a basket procedure (group 1) was based on a prospective nonrandomized study and both groups were compared historically. All 322 patients in group 1 (mean age 49 years, range 14 to 86) primarily underwent ureteroscopic stone basket manipulation using the 4-wire Segura* basket. If the calculus could not be removed with the basket and another procedure was necessary, the case was considered a failure. The 161 patients in group 2 (mean age 37 years, range 14 to 74) underwent initially ultrasound ureterolithotripsy for stone fragmentation followed or not by removal of the fragments with the basket. Stone size did not differ significantly between groups 1 (mean 0.9 cm., range 0.6 to 1.7) and 2 (mean 0.8 cm., range 0.7 to 2.0). Ureteroscopy was performed in both groups with epidural anesthesia and on an outpatient basis in the majority of cases. RESULTS The stone-free rate after 1 procedure was 98.1 and 95.6% in group 1 and 2, respectively. For group 2 versus group 1 the operative time was longer (mean 50, range 25 to 90 versus mean 19 minutes, range 11 to 40, respectively, p < 0.001), the complication rate was greater (16.1 versus 4.3%, respectively, p < 0.001) and average hospital stay was longer (2.1 versus 0.15 day, respectively, p < 0.001). CONCLUSIONS Ureteroscopic stone treatment with basket manipulation under fluoroscopic guidance or ultrasound ureterolithotripsy provided a high stone-free rate. However, stone removal with the basket manipulation technique should be considered the first choice for treatment of small distal ureteral calculi based on the minimal morbidity, and short operative and recovery times.
