Abstract
Herein, we investigated the effect of fish oil supplementation combined with a strength-training protocol, for 6 weeks, on muscle damage induced by a single bout of strength exercise in untrained young men. Sixteen men were divided into two groups, supplemented or not with fish oil, and they were evaluated at the pre-training period and post-training period. We investigated changes before and 0, 24, and 48 h after a single hypertrophic exercise session. Creatine kinase (CK) and lactate dehydrogenase (LDH) activities, plasma interleukin-6 (IL-6) and C-reactive protein (CRP) levels, and the redox imbalance were increased in response to the single-bout session of hypertrophic exercises at baseline (pre-training period) and decreased during the post-training period in the control group due to the repeated-bout effect (RBE). The fish oil supplementation exacerbated this reduction and improved the redox state. In summary, our findings demonstrate that, in untrained young men submitted to a strength-training protocol, fish oil supplementation is ideal for alleviating the muscle injury, inflammation, and redox imbalance induced by a single session of intense strength exercises, highlighting this supplementation as a beneficial strategy for young men that intend to engage in strength-training programs.

Abstract
Coronavirus disease 2019 (COVID-19) is triggered by the SARS-CoV-2, which is able to infect and cause dysfunction not only in lungs, but also in multiple organs, including central nervous system, skeletal muscle, kidneys, heart, liver, and intestine. Several metabolic disturbances are associated with cell damage or tissue injury, but the mechanisms involved are not yet fully elucidated. Some potential mechanisms involved in the COVID-19-induced tissue dysfunction are proposed, such as: (a) High expression and levels of proinflammatory cytokines, including TNF-α IL-6, IL-1β, INF-α and INF-β, increasing the systemic and tissue inflammatory state; (b) Induction of oxidative stress due to redox imbalance, resulting in cell injury or death induced by elevated production of reactive oxygen species; and (c) Deregulation of the renin-angiotensin-aldosterone system, exacerbating the inflammatory and oxidative stress responses. In this review, we discuss the main metabolic disturbances observed in different target tissues of SARS-CoV-2 and the potential mechanisms involved in these changes associated with the tissue dysfunction.

Abstract
Brown adipose tissue (BAT) is a potential target to treat obesity and diabetes, dissipating energy as heat. Type 2 diabetes (T2D) has been associated with obesogenic diets; however, T2D was also reported in lean individuals to be associated with genetic factors. We aimed to investigate the differences between obese and lean models of insulin resistance (IR) and elucidate the mechanism associated with BAT metabolism and dysfunction in different IR animal models: a genetic model (lean GK rats) and obese models (diet-induced obese Wistar rats) at 8 weeks of age fed a high-carbohydrate (HC), high-fat (HF) diet, or high-fat and high-sugar (HFHS) diet for 8 weeks. At 15 weeks of age, BAT glucose uptake was evaluated by 18F-FDG PET under basal (saline administration) or stimulated condition (CL316,243, a selective β3-AR agonist). After CL316, 243 administrations, GK animals showed decreased glucose uptake compared to HC animals. At 16 weeks of age, the animals were euthanized, and the interscapular BAT was dissected for analysis. Histological analyses showed lower cell density in GK rats and higher adipocyte area compared to all groups, followed by HFHS and HF compared to HC. HFHS showed a decreased batokine FGF21 protein level compared to all groups. However, GK animals showed increased expression of genes involved in fatty acid oxidation (CPT1 and CPT2), BAT metabolism (Sirt1 and Pgc1-α), and obesogenic genes (leptin and PAI-1) but decreased gene expression of glucose transporter 1 (GLUT-1) compared to other groups. Our data suggest impaired BAT function in obese Wistar and GK rats, with evidence of a whitening process in these animals.

Abstract
Background and Aim: The prebiotics, mannan-oligosaccharides (MOS), demonstrate the ability to increase probiotic microorganisms and fixation and removal of pathogens associated with chronic systemic inflammation in the digestive system. Inflammatory processes play an important role in modulating the brain-intestinal axis, including maintaining male reproductive function and spermatogenesis and regulating stress. The aim of the present study was to evaluate the action of MOS on testosterone and corticosterone concentrations and the reproductive system development of rats in the growth phase as an animal model. Materials and Methods: In total, 128 male rats were used, randomly divided into four experimental groups (n=32): Control; MOS 1; MOS 2; and MOS 3. From each group, eight animals were sacrificed in four experimental moments (14, 28, 42, and 56 days, respectively, moments 1, 2, 3, and 4) and hormonal measurements and histological evaluations were performed. Results: The results revealed the effect of diet, MOS, and timing on testicle weight (p<0.05). At moments 3 and 4, the groups supplemented with MOS showed higher concentrations of testosterone and decreased corticosterone levels throughout the experimental period. Groups supplemented with MOS showed an increase in the frequency of relative sperm and sperm scores. The radii of the seminiferous tubules presented a significant statistical effect of the diet, moments, and diet + moment interaction. Conclusion: It was concluded that the three different MOS prebiotics brought forward sexual maturity.

Abstract
Numerous conditions are involved in the equilibrium between protective and aggressive factors for gastric mucosa injuring. Among them the lysosomal membrane stability plays a very important role in the inflammatory process. Zinc ion is a well-known lysosomal membrane stabilizer. When given orally to animals or even to humans it protects gastric mucosa against erosive lesions induced by a variety of experimental conditions. Compared with the control group (8.45 +/- 1.49 mU/mg) the lysosomes isolated from samples of gastric mucosa obtained from patients suffering of erosive gastropathies, showed a great liability on their membranes (18.37 +/- 4.52 mU/mg). When these patients were treated orally with zinc sulfate (100 mg of zinc element, twice a day, for two weeks) the lysosomes isolated from their gastric mucosa showed a strong reduction on enzymatic activity (5.49 +/- 1.02 mU/mg), probably due to increasing on the membrane stability. Based on these experimental findings we propose the use of zinc ion as an important adjuvant in treatment of erosive gastropathies.

Abstract
OBJECTIVE Hypomagnesemia occurs in 25-38% of patients with type 2 diabetes. Several studies have suggested an association between magnesium (Mg) depletion and insulin resistance and/or reduction of insulin secretion in these cases. Our purpose was to evaluate if Mg supplementation (as magnesium oxide [MgO]) would improve metabolic control in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS We studied 128 patients with type 2 diabetes (32 men, 96 women, aged 30-69 years), treated by diet or diet plus oral antidiabetic drugs, in the Bahia Federal University Hospital, Brazil. Patients at risk for hypomagnesemia or with reduced renal function were excluded. This study was a clinical randomized double-blind placebo-controlled trial. Patients received either placebo, 20.7 mmol MgO, or 41.4 mmol MgO daily (elementary Mg) for 30 days. Mg concentrations were measured in plasma, in mononuclear cells, and in 24-h urine samples. Fasting blood glucose, HbA1, and fructosamine were used as parameters of metabolic control. RESULTS Of the patients, 47.7% had low plasma Mg, and 31.1% had low intramononuclear Mg levels. Intracellular Mg in patients with diabetes was significantly lower than in the normal population (62 blood donors; 1.4 +/- 0.6 vs. 1.7 +/- 0.6 micrograms/mg of total proteins). No correlation was found between plasma and intracellular Mg concentrations (r = -0.179; P = 0.15) or between Mg concentrations and glycemic control (r = -0.165; P = 0.12). Intracellular Mg levels were lower in patients with peripheral neuropathy than in those without (1.2 +/- 0.5 vs. 1.5 +/- 0.6 micrograms/mg). Similar findings were observed in patients with coronary disease (1.0 +/- 0.5 vs. 1.5 +/- 0.6 micrograms/mg). In the placebo and in the 20.7 mmol Mg groups, neither a change in plasma and intracellular levels nor an improvement in glycemic control were observed. Replacement with 41.4 mmol Mg tended to increase plasma, cellular, and urine Mg and caused a significant fall (4.1 +/- 0.8 to 3.8 +/- 0.7 mmol/l) in fructosamine (normal, 1.87-2.87 mmol/l). CONCLUSIONS Mg depletion is common in poorly controlled patients with type 2 diabetes, especially in those with neuropathy or coronary disease. More prolonged use of Mg in doses that are higher than usual is needed to establish its routine or selective administration in patients with type 2 diabetes to improve control or prevent chronic complications.

Abstract
The inflammatory processes that develop during the advanced stages of hepatic schistosomiasis mansoni have been related in this study to: (a) accumulation of siderosomes; (b) capacity of the ferrous/ferric ions to unleash the formation of free radicals; (c) peroxidation of membrane lipids and; (d) reduction of stability of the membranes of several components of the hepatic lysosomal compartment. The lysosomes isolated from the livers of infected mice by 100 cercariae, with 80 and 100 days of infection, were respectively 2.5 and almost 4 times weaker than the control ones isolated from livers of non-infected mice. The presence of a great quantity of siderosomes has been demonstrated by transmission electronic microscopy and X-ray spectrometry microanalysis.

Abstract
Aiming at investigating the changes on the lipidic constitution of hepatic lysosomal membranes at the initial phase of schistosomatic damage, mice have been infected with 30 cercarias and employed for essais in the 30th day of infection. The triacylglycerois decreased from 220 +/- 48 micrograms/mg of total proteins in the control mice, to 165 +/- 22 micrograms/mg in the infected ones. Similarly, the free cholesterol, also decreased from 539 +/- 80 to 396 +/- 54 micrograms/mg; the cholesterol esters from 270 +/- 35 to 216 +/- 36 micrograms/mg and the phosphatidylcholines from 44 +/- 5.7 to 31 +/- 4.9 micrograms/mg. The phosphatidylserines the phosphatidylethanolamines and the sphingomyelins increased, respectively from 58 +/- 9.7 to 60 +/- 8.5, from 72 +/- 7.8 to 111 +/- 15.7 and from 36 +/- 4.9 to 63 +/- 7.1 micrograms/mg. The free fatty acids showed no statistical significance on their variations. They varied from 1.7 +/- 0.25 microEq/g in the controls to 1.8 +/- 0.39 microEq/g in the infected animals. These results indicated that in the initial phase of hepatic schistosomiasis, before the formation of granulomas, important changes on the lipidic constitution of lysosomal membranes can be detected. It seems that they are provoked by the catabolic excreted by immature or adult worms of Schistosoma mansoni present in the portal vein system.

Abstract
O Schistosoma mansoni e/ou seus ovos causam uma hepatopatia muito importante e com aspectos anátomo-clínicos bem característicos. Uma vez carregados pela corrente circulatória, os vermes podem ocluir ramos dicotômicos de maior calibre do sistema portal e, quando mortos produzem lesões às vezes extensas, primeiro necróticas, depois inflamatórias e, posteriormente cicatriciais, sempre circunscritas e não sistematizadas. Os ovos, além de penetrarem no's ramúsculos não dicotômicos da rede periductal, alcançam os ramos de distribuição ou até mesmo as vênulas aferentes, ocluin- do muitas delas e, como conseqüência, formam os granulomas intravasculares que podem levar a uma interrupção da corrente sangüínea portal a esse nível e alterações da circulação intralobular. A diminuição da taxa de oxigênio disponível e conseqüentemente o decréscimo do pH intra e extracelular são potentes labilizadores das membranas dos diversos componentes do compartimento lisossômico. A saída de hidrolases ácidas, proteínas catiônicas e hidrolases neutras, a partir desses orgãnulos, acarreta agressões tissulares muito importantes, com o desencadeamento e/ou manutenção dos processos inflamatórios típicos desta parasitose. Neste trabalho estudou-se as atividades lisossômicas ligadas às diversas fases da esquistossomose mansônica hepática. Os resultados indicaram que a integridade funcional dos complexos membranosos do compartimento lisossômico foi significativamente alterada, já a partir do segundo mês da infecção e que parece haver um estreito relacionamento entre o agravamento das lesões inflamatórias hepáticas com uma maior labilidade lisossômica.

Abstract
In a prospective study of 50 patients with visceral leishmaniasis, laboratory abnormalities suggestive of renal involvement were not infrequent. Proteinuria and/or microscopic hematuria or pyuria were observed in 51% of such cases. Twenty-four hour urinary protein excretion was elevated in 57% of patients in all cases below 1g/24 hours. An abnormal acid-load test was demonstrated in 12 of 18 patients studied before therapy of the parasitic infection with N-methyl-glucamine. Of interest was the demonstration of tubulo-interstitial involvement in the renal histology of all seven patients studied; also, in five of seven patients there was a proliferative glomerulonephritis, usually mild, on histologic examination. In general, there was a tendency to subsidence of abnormal laboratory findings within one month after specific therapy. Renal involvement in visceral leishmaniasis was mild and seemed to revert with the cure of the leishmanial infection.

Abstract
Gold salts have been widely used in the past 70 years in the treatment of various connective tissue diseases and more particularly in rheumatoid arthritis. However their mechanism of action remains poorly understood. Gold salts are transported in the blood linked with several serum proteins including immunoglobulins. Methods of analytical electron microscopy (Castaing probe) have shown that gold is actively concentrated in the lysosomes of various cell types, including the proximal tubular cells of the kidney and certain bone marrow cells. These data, together with those provided by biochemical techniques, suggest that sodium aurothiopropanol sulfonate modifies the stability of lysosome membranes. In the present study it is shown that the stability of kidney lysosomes of treated rats was increased by 42.4 per cent after treatment for 3 days. This protective action was also seen when lysosomes were subjected to lysis by digitonin. The protective effect of gold salts on the lysosomal membrane may be explained by the formation of chemical complexes between gold and sulfhydryl groups present in the membrane, resulting in stable mercaptic bonds. These findings suggest that the increase in stability of lysosomal membranes plays a significant role in the anti-inflammatory action of gold salts.

Abstract
Foram estudadas mitocôndrias isoladas de fígados e rins de sagüis (Callitrix penicillata) infestados pela inoculação de 200 cercárias e entre 80 e 100 dias de infecção, nos aspectos relativos às suas atividades respiratórias endógenas, bem como frente ao succinato e ao alfa ceto glutarato de sódio. Cada experiência foi acompanhada de controle, usando-se mitocôndrias isoladas de fígados e rins de animais não infectados. As medidas das atividades respiratórias foram efetuadas polarograficamente e expressas em microlitros de oxigênio consumidos por miligrama de proteínas totais por minuto. Os resultados mostraram que as respirações endógenas das mitocôndrias isoladas dos animais infectados foram sempre maiores do que aquelas observadas nos controles. Detectou-se um estímulo para o fígado de 217% e para o rim de 84%. O succinato de sódio estimulou em 85% a respiração das mitocôndrias dos fígados dos animais controles, enquanto a inibiu de 39% nos infectados. Com referência aos rins, este mesmo substrato estimulou a referida respiração tanto nos controles quanto nos infectados, em 89% e 94% respectivamente. O alfa ceto glutarato estimulou as mitocôndrias hepáticas isoladas dos controles em 48% e as renais em 84%. Nos animais esquistossomóticos ou ele não modificou a capacidade respiratória mitocondrial como se observou para o rim, ou a inibiu de 58%, no caso do fígado. Os dados obtidos sugerem que o fígado sofre muito mais, em termos bioquímicos, com a esquistossomose mansônica do que os rins, pelo menos em nossas condições experimentais. As atividades do sistema enzimático succinato desidrogenase e do complexo alfa ceto glutarato desidrogenase permitiram identificar bioquimicamente, em nossos animais esquistossomóticos, vários graus de lesão celular, principalmente hepáticos, que vão desde os mais simples, decorrentes de modificações da físico-química dos sistemas de membranas, até os mais graves, tipo necrose.

Abstract
The effect of the verapamil upon the stability of the membranes of lysosomes isolated from rabbit hearts was studied by means of the acid phosphatase activity, the mapping enzyme of the cytoplasmic organelles. A dose of 2.5 mg of verapamil was injected endovenously in each animal. After homogenization of a sample taken from the lower end of the heart, the lysosomes were isolated by fractionated centrifugation and refrigerated at 2 degrees C. The lysosomal activity of non treated animals was 43.1 +/- 8.9x10(-1)mU/mg. The activity of lysosomes isolated from verapamil treated animals without previous treatment "in vitro" with digitonin was 8.7 +/- 1.6x10(-1)mU/mg and the activity of those with previous treatment of digitonin was 9.1 +/- 2.1x10(-1)mU/mg. The activity of lysosomes isolated from the control group and treated "in vitro" by digitonin was 193.9 +/- 40.5x10(-10)mU/mg. Consequently, the verapamil proved to have a strong capacity of protection of the lysosome membranes when "in vivo".

Abstract
Using the cytoplasmic soluble fraction from rat brain as a source of glutamate decarboxilase, its enzymatic activity was induced by electrical stimulation and determined by gas release. Modified Warburg's flasks were used for such determination. The limits of frequency and the use of sinusoidal waves were based on normal cerebral rhythms. At low frequencies, GAD activity is markedly enhanced (1-10 Hz, 2v, 500 muA). Activation of the enzyme may be due to distortion of the tertiary structure promoting thus an increased coupling between the substrate and the enzyme complex.

Abstract
Acute uremia was induced in male Swiss albino mice by complete urethral ligation and the animals were sacrificed 2, 4-6, 24, and 48 h after operation. Sham-opeated animals (without the urethral ligation) were similarly treated. The blood urea levels of animals with total urinary tract obstruction went up to 175 mg/100 ml at 4-6 h of urethral ligation and reached an average level of 827 mg/100 ml at 48 h, while the control group exhibited and average blood urea level of 37 mg/100 ml. Lysosomes obtained from livers of uremic mice sacrificed at different time intervals demonstrated a lability of the lysosomal membranes (as determined by the acid phosphatase activity in mU/mg) which was maximal at 4-6 h of urethral ligation, declining towards normal at 24 and 48 h, despite an increase in the animal's blood urea. In vitro studies exposing liver lysosomes to progressively higher urea concentrations (differences of as much as 100,000 times) did not reveal any effect of urea upon the stability of lysosomal membranes. The reason for the lability of lysosomal membranes in the uremic group was not apparent in the present study.

Abstract
Modifications of the Warburg's flask were suggested for the study of the electric current effect upon enzymatic systems under directly stimulation "in vitro" and "in vivo" conditions. The proposed modifications made on the Warburg's flask were basically constituted by the insertion of two platinum and mercury electrodes in the principal reservoir. In order to demonstrate the efficiency and viability of the suggested modification, one experience concerning the effect of the electric current upon the cerebral glutamate decarboxylase activity was shown. The apoenzyme substrate system was activated 1.81 times by the electrical stimulation in absence of the coenzyme. In a similar way the complete system, that is, the apoenzyme-coenzyme-substrate was also stimulated. The physical phenomena seem to be of importance for the understanding of the physiology and biochemistry of the nervous tissue.

Abstract
The effect of acute uremia on the liver mitochondrial activity was studied in Swiss albino mice subjected to complete urethral obstruction and sacrificed at different time intervals. The specific respiratory coefficient (measured as microliters of oxygen utilized per milligram of total proteins X 10(-1)) was similar in uremic and sham-operated control groups. The utilization of succinate as substrate was also similar in uremic and controls. There was a tendency for decreasing utilization of alpha-glutarate as substrate by the uremic group, particularly after 48 h of total urinary obstruction. There was no correlation between the retention of urea and the degree of mitochondrial respiratory inhibition.

Abstract
Up to now, the activity of D.A.O. and M.A.O. in the gastric mucosa of rat stomach has not been yet detected. Employing a radioisotopic method, modified by us, it was possible to detect the activity of both enzymes in sufficient amount to study their topographic and intracellular localization. Topographically, the antral region showed the highest activity for the two enzymes, being the D.A.O. 20 times stronger than the M.A.O. The intracellular localization of M.A.O. seems to be in the lysosomes but the D.A.O. looks like to be homogeneously distributed, except in the mitochondrial fraction. The simple demonstration of gastric intracellular distribution of these enzymes in the rat stomach should stimulate further investigations to elucidate the metabolism of histamine and its enzymatic regulations.
