Tannase is a hydrolytic enzyme that is involved in the biodegradation of tannins and it has biotechnological potential in the pharmaceutical, chemical, food and beverage industries. Microorganisms, especially filamentous fungi, are important tannase producers. The aims of this work were to find a potential tannase producer and to improve the cultivation conditions. Three Aspergillus species (A. japonicus 246A, A. tamarii 3 and Aspergillus sp. GM4) were investigated in different culture media (Adams, Czapeck, Khanna, M5 and Vogel) and inducers (1% and 2% tannic acid;1% green tea;1% methyl gallate;1% gallic acid). Aspergillus sp. GM4 and Adams medium were selected. The tannase production by Aspergillus sp. GM4 in Adams medium was induced in the presence of 2% (w/v) tannic acid and gallic acid as carbon sources, while green tea was not able to induce tannase production. The Plackett-Burman screening design was performed with the variables MgSO4, KH2PO4, yeast extract, tannic acid, agitation rate and salt solution. The variables MgSO4 and agitation rate were selected for the optimization of tannase production using a Central Composite Rotatable Design. Under optimized conditions, a 2.66-fold increase in the enzyme production was observed with small modifications in the medium composition.

Previously,it was suggested that biological maturation(BM)could be linked to cardiac autonomic recovery(CAR)in the pediatric ***,this influence hasn’t been confirmed *** aim was to investigate the impact of BM on CAR in female volleyball *** study with a sample of 38 volleyball players,comprising 20 girls(age:[11.62.1]years)and 18 women(age:[24.55.5]years),we analyzed BM,comparing maturing subjects(girls)with mature subjects(women).Additionally,we assessed peak height velocity(PHV)in *** conducted a training session involving repeated sprints(3 rounds of 6 sprints interspersed by 5 min[min]of passive rest).Using short-range radio telemetry,we analyzed CAR during(at the end of the 1st and 2nd rounds)and after(following the 3rd round)the training session of repeated sprints by applying the 60-s to 300-s heart rate recovery index(HRR-Index).Girls exhibited superior CAR compared to women(round 2:60-s,120-s,240-s,and 300-s,p0.4,p0.4,p<0.05).We have concluded that biological maturation has a significant impact on cardiac autonomic recovery.

Evidence-Based Complementary and Alternative Medicine Effects of Capybara Oil on Cardiac Remodeling of C57bl/6 Mice

Journal of Biosciences and Medicines 2024年第5期12卷 213-232页

Cardiovascular diseases are the main cause of morbidity and mortality in the world, and obesity and the metabolic syndrome are risk factors for its development. One of the therapies to reduce cardiovascular risk is the use of polyunsaturated fatty acids. In Brazil, a source of such acid is the oil extracted from the fat of the capybara. The objective of this work is to study the effects of the capybara oil on lipid and glucose metabolism, as well as its effects on the adipose tissue and cardiac remodeling. We assessed the effects of capybara oil treatment on body mass, lipid and carbohydrate metabolism, systolic blood pressure, adipose tissue and cardiac remodeling, and performed an ultrastructural evaluation of the myocardium in C57Bl/6 mice treated with high-fat diet. Treatment with capybara oil reduced total cholesterol and triglyceride levels, systolic blood pressure, visceral and subcutaneous adipose tissue, and adipocyte diameter. In addition, cardiac remodeling was attenuated, preserving cardiomyocytes, increasing vascularization, reducing cardiomyocyte hypertrophy and the extracellular matrix, and preserving the morphological integrity of mitochondria. Capybara oil has several beneficial effects on the cardiovascular and metabolic system, and further studies are needed to better understand its role in the prevention or treatment of cardiovascular diseases.

Background: Alzheimer’s disease is a progressive and neurodegenerative disorder characterized by deterioration of brain functions. Psychosocial interventions such as music and photographic stimuli may contribute to cognitive and sensory exercise or rehabilitation. Objective: Evaluate musical and photographic stimuli in elderly people with Alzheimer’s disease. Methods: It is an uncontrolled clinical trial, before-after type, eleven subjects composing the sample. Participants were submitted to Katz Index, Autobiographical Memory Test, GDS-15, Mini-Mental State Examination. The collection instruments were used on the first and last day of intervention, individually. There were 2 sessions in the week with duration of 50 minutes totaling 20 sessions. Data were analyzed by descriptive and inferential statistics and as variables expressed as mean standard deviation. Results: There was a significant effect of cognitive activity (P , it was observed that a small advance (P = 0.05) of the daily life activities. With the analysis of GDS-15, it is verified that they are more effective for the increase of the previous self-estimation of the therapy (P = 0.94). In the application of the AMT, it is observed that there was a better recruitment of the memory for the neutral words. Conclusion: Musical and photographic stimuli had a positive effect on the cognitive level, daily life activities and autobiographical memory in seniors with Alzheimer’s disease.

In this case report, we present a male patient who arrived at the hospital for the first time at the age of 8 with giant keloids in both ears and diagnosed by the Dermatology and Plastic Surgery as having the “Disease of Jorge Lobo”, which is a fungal infection due to the story of the endemic characteristics. After the first surgical intervention, he received guidance from the team for keloids and left the hospital using elastic mesh and a request to change the place where he lived to reduce his contact with the fungi. Fourteen years later, the patient returned to the Plastic Surgery Service having even larger keloids in both ears, twice the size than the first time. We did the second surgical intervention to remove it, but with the patient’s commitment that he would correctly comply with the guidelines determined by the surgical team. After finishing all the steps and a post-operative for the case, we observed the satisfaction and the increase of the patient’s mood, happier and without the embarrassment of that physical defect.
