Abstract
BACKGROUND Lychnophora ericoides Mart, also known as the Brazilian arnica or fake arnica, belongs to the Asteraceae family. Leaves and roots are used in alcoholic and hydroalcoholic preparations for the treatment of wounds, inflammation, and pain. PURPOSE The present study aimed to investigate the effects of L. ericoides ethanolic extract (EELE) on cutaneous wound healing and the mechanisms of action involved. METHODS A total of 72 C57BL/6 mice were randomly divided into four groups of six animals each. An excisional wound was made in the dorsal region of each mouse. The test groups were topically treated with the vehicle, a positive control commercial reference drug, EELE ointment (5%), and EELE ointment (10%). The treatments were applied over 14 days. The wound area was measured every two days to verify the wound closure kinetics. On days 3, 7, and 14 the wound tissue samples were processed for Hematoxylin and Eosin, Masson-Trichrome, and Toluidine blue staining. The expression of renin-angiotensin system (RAS) components, the vascular growth factor-A (VEGF-A), the basic fibroblast growth factor (FGF-2), and type I collagen genes were evaluated. Phytochemical analyses were performed using HPLC-DAD and HPLC-MS/MS. RESULTS The EELE (10%) significantly reduced the wound area compared to the treatments used for the other groups. Histological analysis demonstrated that wounds treated with L. ericoides for 14 days developed improved anatomical skin features, healed with hair follicles and sebaceous glands, increased collagen production and angiogenesis, and decreased the number of mast cells at the injury site. Real-time PCR data demonstrated that groups treated with EELE (10%) showed increased Type I collagen, VEGF-A, FGF-2, and AT1R and decreased ACE II and receptor MAS. The healing action of L. ericoides may be related to the presence of phenolic compounds, such as phenolic acids, chlorogenic acid derivatives, and C-glycoside flavonoids. CONCLUSION Topical treatment with EELE increases important factors for wound healing: FGF, VEGF, collagen formation, and the expression of the proliferative axis of the renin-angiotensin system. For the first time, the present study shows the healing action of L. ericoides at the molecular level in an animal model. This process can be used as an alternative therapy for wound healing and the development of herbal therapy.

Abstract
BACKGROUND Diet macronutrient heterogeneity hinders animal studies' data extrapolation from metabolic disorders to human diseases. OBJECTIVE The present study aimed to evaluate different fat-diet compositions' effect on inducing lipid/glucose metabolism alterations in mice. METHODS Swiss male mice were fed for 12 weeks with five different diets: Standard Diet (ST), American Institute of Nutrition 93 for growth (AIN93G) high-butter/high-sugar (HBHS), high-lard/high-sugar (HLHS), and high-oil/high-sugar diet (soybean oil) (HOHS). Several parameters, such as serum biochemistry, histology, and liver mRNA expression, were accessed. RESULTS The main findings revealed that the HLHS diet dramatically altered liver metabolism inducing hepatic steatosis and increased total cholesterol, triglycerides, VLDL, increasing liver CCAAT/enhancer binding protein (CEBP-α), Acetyl-CoA carboxylase (ACC) and Catalase (CAT) mRNA expression. Moreover, the HLHS diet increased glucose intolerance and reduced insulin sensitivity. CONCLUSIONS High-fat/high-sugar diets are efficient to induce obesity and metabolic syndrome-associated alterations, and diets enriched with lard and sugar showed more effective results.

Abstract
Obesity and metabolic disorders represent a significant global health problem and the gut microbiota plays an important role in modulating systemic homeostasis. Recent evidence shows that microbiota and its signaling pathways may affect the whole metabolism and the Renin-Angiotensin System (RAS), which in turn seems to modify microbiota. The present review aimed to investigate nutritional implications in the mechanistic link between the intestinal microbiome, renin-angiotensin system, and the development of obesity and metabolic syndrome components. A description of metabolic changes was obtained based on relevant scientific literature. The molecular and physiological mechanisms that impact the human microbiome were addressed, including the gut microbiota associated with obesity, diabetes, and hepatic steatosis. The RAS interaction signaling and modulation were analyzed. Strategies including the use of prebiotics, symbiotics, probiotics, and biotechnology may affect the gut microbiota and its impact on human health.

Abstract
PURPOSE This study aimed to compare the efficacy of Antimicrobial Photodynamic Therapy (aPDT) with 300 µmol/L of methylene blue and 8 µmol/L of curcumin on oral candidiasis patients with HNSCC undergoing treatment. METHODS A two-arm, single-blind clinical trial was performed. Following verification for eligibility (n = 447), 108 patients were included in the study. The study consisted of a group that received aPDT with methylene blue (n = 57) and another that received aPDT with curcumin (n = 51). The patients rinsed their mouths with an aqueous solution of 300 µmol/L of methylene blue and 8 µmol/L of curcumin in four sessions, and then the lesion was scraped for the subsequent RT-qPCR. The primary outcome was that no cure was presented for oral candidiasis after treatment. The secondary result was reducing the number of sites affected by oral candidiasis. RESULTS There was no difference in treatment failure evaluated by the necessity of drug prescription or Candida sp DNA quantification. However, clinically the methylene blue protocol reduced the number of infected anatomical sites compared to the curcumin protocol. CONCLUSION Methylene Blue aPDT reduced the number of infected anatomical sites compared to curcumin.

Abstract
Background:
Homeopathy is an alternative therapy that uses substances dilution. The homeopathic preparation of Syzygium jambolanum (SJ) has potential use in the treatment of glycemic disorders.
Objective:
In this context, the aim of the present study was to evaluate the use of the SJ homeopathic preparation on treating obesity and glycemic/metabolic disorders compared with metformin treatment (diabetes gold-treatment) in a mice model fed a high-fat diet.
Method:
A total of 48 male Swiss mice were divided into six groups with eight animals each, randomly distributed as follows: obese and non-obese groups (ST), treated and non treated with SJ or metformin. Obesity was induced by high-fat/high-sugar diet, while the control mice (ST) received a standard diet for 12 weeks, after which, for 30 days, the animals received a preparation of 20 µl/100g/body-weight of SJ or a dose of 250 mg/kg metformin (by gavage). The control groups ST and HFHS received water gavage. Body composition and biochemical parameters were evaluated. The adipose genes for lipogenesis and thermogenesis were tested.
Results:
The mice treated with Syzygium jambolanum presented reduced weight gain (p< 0.02) and smaller adipose tissue weight, average difference from the mice treated with metformin, and both groups showed improved insulin sensitivity (p<0.04). The main results were associated with the modulation of the adipogenesis pathway (C/EPBα and PPARγ) and to the thermogenic gene Uncoupling Protein 1 (UCP1).
Conclusion:
Homeopathic administration of the Syzygium jambolanum preparation leads to lower body weight, blood glucose and total cholesterol and higher high-density lipoprotein (HDL), pointing its efficiency on treating diabetes and obesity.

Abstract
BACKGROUND Neutrophil extracellular traps (NETs) are a recently discovered neutrophil defense mechanism which modulates several inflammatory conditions contributing to metabolic profile alterations. Therefore, the present study aimed to evaluate the production of NETs in obese patients and mice, verifying the possible mechanisms associated with the release of NETs by the adipose tissue. METHODS AND RESULTS The present study investigated NETs production in human adipose tissue and also showing the neutrophils using intravital microscopy in mouse epididymal adipose tissue. Blood and white adipose tissues were obtained from eutrophic and obese individuals and from mice. Lipid, glycemic and leukocyte profiles were evaluated, as well as the levels of NETs and its markers. Bioinformatics and proteomics analyses were performed and the identified key proteins were measured. The main findings showed that the inflammatory markers interleukin-8 (IL-8), heat shock protein 90 (HSP90) and the E1 heat shock protein family (HSPE1) can be modulated by the NETs levels in obesity. Obesity has also been associated with increased cholesterol, glucose intolerance, ionic calcium and NETs. We also observed an increase in catalase and a decreased superoxide dismutase activity. Bioinformatics and proteomics analyses revealed that IL-8, HSP90 and HSPE1 were associated with obesity, inflammation and NETs release. CONCLUSIONS In conclusion, the present study shows an increase in NETs production during obesity associated with important inflammatory markers in adipose.

Abstract
The present article reviews the textiles effects in the wounds healing process, as well as these products availability in the market. A brief applications description is given based on the literature obtained from searches in scientific databases, besides the data obtained from secondary sources as books and congress proceedings. The historical context of the textiles uses in wounds, their general characteristics, particularities in the healing process, and incorporation of new technologies are discussed. It was evidenced that the textiles and associated technologies might influence directly or indirectly the stimulation of collagen, cell migration, angiogenesis, reduction of pro-inflammatory factors and fibroblasts. However, the mechanisms by which the textiles act in the healing process are not well established in the literature. The interaction among the textile engineering, biotechnology, medicine and pharmacology is essential for the improvement and development of new products with better efficiency and accessibility.

Abstract
Gomphrena virgata Mart. popularly known as 'Cangussu-branco', is used in Brazilian folk medicine to treat inflammations and infections. This work aimed to carry out phytochemical analysis and evaluate the anti-inflammatory potential of Gomphrena virgata. In the phytochemical investigation, in addition to the presence of two ecdysteroids, 20 R-dihydroxyecdysone and 20-hydroxyecdysone, identified by HPLC-PDA-MS and NMR, 22 compounds were identified by GC-MS. In the cytotoxicity study, the aqueous extract of the roots of this species did not show in vitro toxicity of PBMCs in the concentrations of 250, 500 and 1000 µg/mL when analyzed by the trypan blue exclusion method. Also, it was effective in reducing lymphocyte proliferation, stimulated with the mitogen PHA, by 26.02%, 48.57% and 50.49% when compared to dexamethasone, respectively. In this work we present information about the phytochemicals of G. virgata, showing that the species is promising in obtaining compounds with medicinal potential mainly anti-inflammatory potential.

Abstract
Visceral leishmaniasis (VL), also known as ‘calazar’, is a serious chronic disease caused by Leishmania species from Leishmania (Leishmania) donovani complex, which the disease is characterized by abdominal swelling (hepatosplenomegaly) and may evolve to death in extreme cases. In this sense, the aim of our study was to assess the epidemiological profile of the cases found in Montes Claros (Minas Gerais state). A retrospective or cross-sectional study was carried out using secondary data provided by Health Information System (SINAN/HM) of Brazil from January 2010 to February 2020. Our data has shown that VL is an endemic disease in Montes Claros region, with 413 VL cases reported, 62.00% (252) male, average age ± standard deviation (years), and 93.46% (386) lived in Montes Claros city. The presence of comorbidities was observed in 13.70% (54) of the patients and in 7.26% (30). As for the evolution of the disease, 246 (59.56%) were cured, 30 (7.26%) died due to VL. Between 2010 and 2015, Glucantime® stands out, in which 46 (11.13%) patients used the drug, followed by common Amphotericin B 24 (13.48%) and liposomal Amphotericin B 38 (21.34%). In the period between 2016 and 2020, the most prevalent drug was liposomal Amphotericin B, with 71 (29.83%) patients using it, followed by Glucantime® 45 (18.9%). The condition evolved to death. We conclude that Montes Claros is still an endemic area for VL with an increased number of cases over time and a noticeable shift in patient profile towards children and young people. Joint efforts from different areas of scientific knowledge and public health services are needed to improve the effectiveness of visceral leishmaniasis surveillance and control actions. The population can contribute to this process of disease prevention and control, through educational actions in health and the environment.

Abstract
Renin-Angiotensin System (RAS) is an important peptide cascade involved in physiological processes. RAS homeostasis disruption produces several cardiovascular and metabolic disorders, such as arterial hypertension, atherosclerosis, acute myocardial infarct, obesity, diabetes, metabolic syndrome and increases gastrointestinal tract (GIT) cell proliferation. Angiotensin (Ang)-(1-7) peptide is the main RAS counter-regulatory axis effector. It is formed from ACE2 enzyme and acts mainly through Mas receptor (MasR). In this context, the aim of the present study was to evaluate alterations in small intestine morphology and intestinal microbiota composition in MasR knockout C57BL/6 mice. We analyzed glucose tolerance; insulin sensitivity and blood collected for biochemical parameters as well as small intestine tissues samples for immunohistochemistry. mRNA and bacteria gDNA expression evaluation. mRNA expression was evaluated by qRT-PCR for TLR4, PI3K and AKT. The main results showed that Mas-R-knockout mice presented lower body weight. MasR-knockout mice also presented increased fasted blood glucose and total cholesterol with reduced HDL, lower glucose tolerance and impaired insulin sensitivity. Increased intestinal mucosa length, increased intestinal villi, reduced Lieberkühn crypt depth. The increased expression of cell proliferation markers Ki-67 and Cyclin D1 and increased TLR4, PI3K and AKT expressions were observed with augmented Bacteroidetes and decreased amount of Firmicutes. That results suggests that MasR deletion generated changes in intestinal microbiota, possibly due to a lower neutral amino acids absorption followed by a compensatory increase in intestinal villi length associated with disbiosis and LPS overproduction that ultimately lead to proliferation and cell inflammation.
