RESUMO
In this study, we present a novel approach for the exfoliation of titanium nitride (TiN) powders utilizing a rapid, facile, and environmentally friendly non-thermal plasma method. This method involves the use of an electric arc and nitrogen as the ambient gas at room temperature to generate ionized particles. These ionized species interact with the ceramic crystal of TiN, resulting in a pronounced structural expansion. The exfoliated TiN products were comprehensively characterized using transmission electron microscopy, X-ray diffraction, and Raman spectroscopy. Remarkably, the cubic crystal structure of TiN was effectively retained, while the (200) crystal plane d-spacing increased from 2.08 to 3.09 Å, accompanied by a reduction in crystallite size and alterations in Raman vibrational modes. Collectively, these findings provide compelling evidence for the successful exfoliation of TiN structures using our innovative non-thermal plasma method, opening up exciting possibilities for advanced material applications.

RESUMO
PURPOSE: The objective of this systematic literature review was to investigate the effects of the clinical application of bone marrow aspirate (BMA) and/or bone marrow aspirate concentrate (BMAC) in tendon and cartilage injuries in the foot and ankle. METHODS: A search of the Embase, MEDLINE/PubMed, CINAHL, and Cochrane databases was performed in January 2021. The risk of bias of the studies was assessed using the tool "A Cochrane Risk of Bias Assessment Tool for Non-Randomized Studies." The outcomes analyzed included pain reduction and functional improvement with the use of BMA/BMAC in patients with tendon and cartilage injuries in the foot and ankle. RESULTS: Eleven studies met the inclusion criteria for analysis, involving a total of 527 subjects with osteochondral lesions (OCLs) of the talus, cartilage lesions of the talus, and acute Achilles tendon rupture. BMAC was applied alone in 4 studies, and in 7 studies, it was compared with other techniques such as matrix-induced autologous chondrocyte implantation, particulate juvenile articular cartilage, or microfracture. Interventions demonstrated improved function and reduced foot and ankle pain and showed no serious adverse effects. CONCLUSIONS: Evidence indicates that BMAC provides good clinical results, with improved function and reduced pain in adults with OCL and cartilage lesions of the talus and acute Achilles tendon rupture. LEVEL OF EVIDENCE: Level IV, systematic review of level II to IV studies.

BACKGROUND: At energy distribution companies, office and operational employees work in different occupational environments. Cardiovascular diseases (CVD) can develop due to occupational factors and can often lead to morbidity and disability. OBJECTIVE: To evaluate the risk of CVD in workers with different occupations in an energy distribution company, using cardiometabolic indices. METHODS: Workers (men), aged between 20 and 70 years, were divided into two groups: operational (nâ=â78) and office (nâ=â106) workers. Their metabolic profiles were analyzed using anthropometric and laboratory data to obtain the atherogenic plasma index (AIP) and insulin resistance index (TyG), and to identify the hypertriglyceridemic waist (HTGW) phenotype as cardiometabolic indicators. RESULTS: There was no difference in CVD risk between the two groups. However, 82% of the test subjects presented a high risk for the development of atherosclerosis based on the AIP, and 11.4% presented the HTGW phenotype, along with the presence of dyslipidemia, insulin resistance, and being overweight as risk factors for CVD. CONCLUSIONS: Although the identified risk factors are not related to the type of occupation at work, companies in the electricity sector can invest in the implementation of measures for health promotion to protect and prevent diseases and improve labor productivity and quality.

RESUMO
Las infecciones por Helicobacter pylori son muy comunes en nuestro entorno, en muchos casos se presentan como asintomáticas o con afecciones gastrointestinales, pero no se deben tomar a la ligera, es una infección que puede llevar a graves consecuencias, desde gastritis hasta cáncer gástrico. Su tratamiento se ha estado modificando por casos de resistencia a los medicamentos de primera línea en distintos países. Se realizó una recopilación de datos a través de PubMed, HINARI, SciELO, SCOPUS y Cochrane Library. Los probióticos se utilizan para incrementar el rango de erradicación de la bacteria, la disminución de la bacteria, pero esto acompañado de un tratamiento adecuado, mejora de dieta, sistema inmune del paciente. Debido a que reduce los efectos secundarios en pacientes, promueve un restablecimiento microbiota gastrointestinal, la cual es afectada ante agentes patógenos como el H. pylori.
Helicobacter pylori infections are very common in our environment, in many cases they present as asymptomatic or with gastrointestinal conditions, but they should not be taken lightly, it is an infection that can lead to serious consequences, from gastritis to gastric cancer. Its treatment has been changing due to cases of resistance to first-line drugs in different countries. Data collection was performed through PubMed, HINARI, SciELO, SCOPUS, and Cochrane Library. Probiotics are used to increase the range of eradication of the bacteria, as well as the reduction of the bacteria, but this is accompanied by adequate treatment, diet improvement, the patient's immune system, because it reduces side effects in patients. It is because it promotes a restoration of the gastrointestinal microbiota, which is affected by pathogens such as H. pylori.
RESUMO
The use of selective barriers as resorbable membranes has become a routine clinical procedure for guided bone regeneration. Therefore, the production of membranes with a low inflammatory potential during their resorption process has become the goal of a considerable number of researches. Aim: The purpose of the present study was to evaluate the biocompatibility of poly (L- lactic acid) (PLLA) and biocelulose membranes (BC) inserted in the subcutaneous tissue on the dorsum of rats. Methods: Fifteen animals underwent surgical procedures for the insertion of 4 types of membranes: COL (Collagen membrane) Control Group; BC (Biocellulose membrane); BCAg (Biocellulose membrane impregnated with Silver); PLLA (Poly (L-lactic acid) membrane). All membrane types were inserted into each animal. Animals were euthanized after 3, 7, and 15 days of the surgical procedure. Descriptive histological analyses were carried out to investigate host tissue reaction to membrane presence by assessing the anti-inflammatory process composition associated with the membrane resorption and the presence of foreign-body reaction or encapsulation. Results: The BC membranes showed a higher degree of inflammation and poor pattern of integration with the surrounding tissues than the PLLA and COL membranes. Conclusion: The PLLA and COL membranes present better biocompatibility than the BC membranes

Environmental contamination caused by inorganic compounds is a major problem affecting soils and surface water. Most remediation techniques are costly and generally lead to incomplete removal and production of secondary waste. Nanotechnology, in this scenario with the zero-valent iron nanoparticle, represents a new generation of environmental remediation technologies. It is non-toxic, abundant, cheap, easy to produce, and its production process is simple. However, in order to decrease the aggregation tendency, the zero-iron nanoparticle is frequently coated with chemical surfactants synthesized from petrochemical sources, which are persistent or partially biodegradable. Biosurfactants (rhamnolipids), extracellular compounds produced by microorganisms from hydrophilic and hydrophobic substrates can replace synthetic surfactants. This study investigated the efficiency of a rhamnolipid biosurfactant on the aggregation of nanoscale zer-valent iron (nZVI) and its efficiency in reducing nitrate in simulated groundwater at pH 4.0. Two methods were tested: 1) adding the rhamnolipid during chemical synthesis and 2) adding the rhamnolipid after chemical synthesis of nZVI. Scanning electron microscopy field emission, X-ray diffractometry, Fourier transform infrared spectroscopy, thermogravimetric analysis, Dynamic Light Scattering, and zeta potential measurements were used to characterize bare nZVI and rhamnolipid-coated nZVI. The effects of the type of nZVI and initial NO3 concentration were examined. Nanoscale zer-valent iron with the addition of the rhamnolipid after synthesis achieved the best removal rate of nitrate (about 78%), with an initial nitrate concentration of 25 mg L-1. The results suggest that nZVI functionalized with rhamnolipids is a promising strategy for the in situ remediations of groundwater contaminated by NO3, heavy metal, and inorganic carbon.
RESUMO
Obesity is the most common nutritional disorder in dogs and it is associated with many comorbidities. Some obesity risk factors have already been established, however, the evaluation of the effect of different individual variables on weight loss induced by calorie restriction, although very important, is still poorly explored. The weight loss protocol can be updated and improved by more precise and adjusted equations throughout the weight loss program in the clinical routine practice. Therefore, the objective of this study was to analyze weight loss program dynamics in groups according to reproductive status, age, body size, and breed, as well as to define more accurately the amount of calories per target metabolic weight throughout the program. Data of 1,053 cases, presented between 2012 and 2019 at the Veterinary Hospital of the School of Veterinary Medicine and Animal Science of the University of São Paulo (FMVZ-USP) were retrospectively analyzed. A total of 77 obese dogs (body condition scores 8/9 or 9/9) of different ages, breeds, sizes, and reproductive status were selected. These dogs did not have any concomitant illnesses and successfully completed the weight loss program. Statistical analysis was performed and values of p≤0.05 were considered significant. The proposed weight loss program was based on an energy restriction protocol where daily energy intake (in kcal) was estimated as 70 kcal × target weight0.75. The target weight (TW) was defined as 80% of the animal's current weight. The average calorie intake for weight loss (calories x target weight0.75) was lower for spayed females (62.36), differing from intact males (66.14) and neutered males (65.41), while intact females (63.66) showed intermediate values without differing between groups (p = 0.015). There were no differences between weight loss calories according to age (p = 0.473) or body size (p = 0.084), allowing the use of the same mathematical equation for intact and neutered dogs; for dogs older than 1 year and of different body sizes. Regarding the breed, the average calorie intake was lower (p = 0.002) in mixed breed dogs (61.54xTW0.75) when compared to obesity-prone purebred dogs (64.17xTW0.75) and other purebreds (65.27xTW0.75). It was concluded that spayed females and mixed breed dogs have greater difficulty in losing weight, that is, they need fewer calories per metabolic body weight for the weight loss program to succeed. A more accurate equation for energy requirement for weight loss can improve chances of success, therefore improving compliance and helping clinical management of obesity in dogs.

The search for an effective etiologic treatment to eliminate Trypanosoma cruzi, the causative agent of Chagas disease, has continued for decades and yielded controversial results. In the 1970s, nifurtimox and benznidazole were introduced for clinical assessment, but factors such as parasite resistance, high cellular toxicity, and efficacy in acute and chronic phases of the infection have been debated even today. This study proposes an innovative strategy to support the controlling of the T. cruzi using blue light phototherapy or blue light-emitting diode (LED) intervention. In in vitro assays, axenic cultures of Y and CL strains of T. cruzi were exposed to 460 nm and 40 µW/cm2 of blue light for 5 days (6 h/day), and parasite replication was evaluated daily. For in vivo experiments, C57BL6 mice were infected with the Y strain of T. cruzi and exposed to 460 nm and 7 µW/cm2 of blue light for 9 days (12 h/day). Parasite count in the blood and cardiac tissue was determined, and plasma interleukin (IL-6), tumoral necrosis factor (TNF), chemokine ligand 2 (CCL2), and IL-10 levels and the morphometry of the cardiac tissue were evaluated. Blue light induced a 50% reduction in T. cruzi (epimastigote forms) replication in vitro after 5 days of exposure. This blue light-mediated parasite control was also observed by the T. cruzi reduction in the blood (trypomastigote forms) and in the cardiac tissue (parasite DNA and amastigote nests) of infected mice. Phototherapy reduced plasma IL-6, TNF and IL-10, but not CCL2, levels in infected animals. This non-chemical therapy reduced the volume density of the heart stroma in the cardiac connective tissue but did not ameliorate the mouse myocarditis, maintaining a predominance of pericellular and perivascular mononuclear inflammatory infiltration with an increase in polymorphonuclear cells. Together, these data highlight, for the first time, the use of blue light therapy to control circulating and tissue forms of T. cruzi. Further investigation would demonstrate the application of this promising and potential complementary strategy for the treatment of Chagas disease.

Rhamnolipids are glycolipid biosurfactants that have remarkable physicochemical characteristics, such as the capacity for self-assembly, which makes these biomolecules a promising option for application in nanobiotechnology. Rhamnolipids produced from a low-cost carbon source (glycerol) were used to stabilize silver nanoparticles. Silver nanoparticles (AgNPs) have been the subject of studies due to their physical chemical as well as biological properties, which corroborate their catalytic and antimicrobial activity. We compared nanoparticles obtained with three different pH values during synthesis (5, 7 and 9) in the presence of rhamnolipids. Dynamic light scattering showed that larger particles were formed at pH 5 (78-190 nm) compared to pH 7 (6.5-43 nm) and 9 (5.6-28.1 nm). Moreover, nanoparticle stability (analyzed based on the zeta potential) was enhanced with the increase in pH from 5 to 9 (-29.86 ± 1.04, -37.83 ± 0.90 and -40.33 ± 0.57 mV, respectively). Field emission gun scanning electron microscopy confirmed the round morphology of the silver nanoparticles. The LSPR spectra of AgNP for the pHs studied are conserved. In conclusion, different pH values in the presence of rhamnolipids used in the synthesis of silver nanoparticles directly affect nanoparticle size and stability.

RESUMO
BACKGROUND: The knowledge of how owners view the body condition of their animals is an important factor for the success of the prevention/treatment of obesity and the engagement/adherence to nutritional interventions, which are fundamental to improve the animal prognosis. For this reason, the objective of this study was to evaluate the perception of the owners regarding the body condition score of their animals, compare the perception between cat vs. dog owners, and owners from the countryside vs. metropolitan region of São Paulo State in Brazil. RESULTS: 601 dogs and 110 cats were included in this study. There was no significant difference in body condition score assigned by owners by species. Owners of dogs and cats classified by the veterinarian as ideal, overweight, and obese who disagree with body condition score assigned by veterinarian mainly underestimate the body condition score of their animals, while lean dogs' owners overestimate it. Countryside dog owners had a higher rate of disagreement with the veterinarian and more often underestimate the body condition score than owners from the metropolitan region. The owners of lean cats have the same judgments with veterinarians. CONCLUSIONS: Owners of dogs and cats have difficulty assessing the body condition score, especially owners from countryside.

RESUMO
Objetivo: Analisar a prevalência de lesões em órgãos-alvo. Métodos: Foi realizado estudo transversal e retrospectivo utilizando dados do Sistema de Cadastramento e Acompanhamento de Hipertensos e Diabéticos considerando diabéticos tipo 2 do Estado de Minas Gerais, entre os anos de 2003 e 2012. Foram analisadas quatro lesões características da má evolução do diabetes mellitus tipo 2: infarto agudo do miocárdio, acidente vascular cerebral, pé diabético e doença renal crônica. Resultados: Foram encontrados 36.270 diabéticos tipo 2. O infarto agudo do miocárdio acometeu 2,9% dos pacientes, gerando 1.087 casos. A idade mais atingida foi acima de 40 anos. O acidente vascular cerebral acometeu 2,4% dos diabéticos, provocando 892 ocorrências. A idade de maior prevalência se situou entre 50 e 64 anos, sendo responsável por 41,4% dos casos. O sexo feminino apresentou superioridade, sendo responsável por 56% dos casos. O pé diabético foi registrado em 1.160 pacientes, somando 3,1% do total de diabéticos. A doença renal crônica foi a lesão secundária ao diabetes mellitus tipo 2 mais prevalente no estado, gerando 2.094 registros, o que representa 5,7% do total de diabéticos. O sexo feminino foi consideravelmente mais acometido (65,1% dos casos), sendo a faixa etária entre 45 e 64 anos a mais prevalente. Conclusão: Este estudo sobre a prevalência e os fatores de risco para o desenvolvimento de lesões secundárias em diabéticos tipo 2 de Minas Gerais permitiu identificar que se trata de complicações muito prevalentes no Estado, e que os aspectos clínicos analisados constituem importantes fatores de risco para a má evolução da doença.

Objective: To analyze the prevalence of target organ damage. Methods: A cross-sectional and retrospective study was performed using data from the Hypertensive and Diabetic Patients Registry and Monitoring System considering type 2 diabetes patients from the state of Minas Gerais, from 2003 to 2012. Four characteristic lesions due to poor evolution of type 2 diabetes mellitus were analyzed: acute myocardial infarction; Stroke; Diabetic foot; Chronic kidney disease. Results: A total of 36,270 type 2 diabetic patients was found. Acute myocardial infarction affected 2.9% of the patients, generating 1,087 cases. The most affected age was over 40 years. Stroke affected 2.4% of diabetics, causing 892 occurrences. The highest prevalence age was between 50 and 64 years, accounting for 41.4% of the cases. The female gender was prevalent, being responsible for 56% of the cases. The diabetic foot was recorded in 1,160 patients, accounting for 3.1% of the total number of diabetics. Chronic kidney disease was the most prevalent lesion secondary to diabetes mellitus in the state, generating 2,094 records, representing 5.7% of the total number of diabetics. The female gender was considerably more affected (65.1% of the cases), with the age group between 45 and 64 years being more prevalent. Conclusion: This study of the prevalence and risk factors for the development of secondary lesions in type 2 diabetics from Minas Gerais allowed us to identify that these are very prevalent complications in the state, and that the clinical aspects analyzed are important risk factors for poor outcome of the disease.

La siguiente investigación aborda desde una perspectiva crítica los imaginarios de infancia criminalizada de terapeutas ocupacionales que trabajan con niños, niñas y adolescentes criminalizados/as en programas de prevención de riesgo psicosocial y programas con y sin sanción penal, con el objetivo de conocer las implicancias de estos imaginarios en la praxis de la profesión.MetodologíaSe realizaron entrevistas en profundidad a siete terapeutas ocupacionales. Posteriormente se elaboró un análisis categorial de contenidos.Resultados La etapa infanto adolescente es referida como exploratoria, compleja y fundamental para la constitución de la personalidad adulta. Los imaginarios se asocian a una serie de situaciones que pueden llevar al niño, niña o adolescente a vincularse con la actividad delictual (familismo, deserción escolar, escaso apoyo de instituciones públicas, sistema neoliberal, consumismo). Los centros de prevención realizan intervenciones en espacios cotidianos y promueven instancias de participación ocupacional, mientras que en centros cerrados con sanción penal, se realizan principalmente actividades para la reinserción sociolaboral.discusiónExisten diversidad de perspectivas en torno a las intervenciones, existiendo diferencias significativas entre los imaginarios de quienes trabajan en contextos de población sancionada y quienes no.Las limitaciones gubernamentales restringen de diversas maneras las expectativas y proyecciones de las intervenciones, confrontando a los imaginarios con lo propuesto en la declaración internacional de los derechos del niño y la niña.
The following research approaches from a critical perspective the criminalized childhood imaginary of occupational therapists who works in psychosocial prevention programs and closed treatment centers, whose users are criminalized children and adolescents with and without criminal sanction, in order to know the implications of this issue has in the praxis of the profession.MethodologyIn-depth were done to seven occupational therapists. Afterwards, a categorical content analysis was elaborated.ResultsThe childhood and teenage stage is referred to as exploratory, complex and fundamental for the constitution of the adult personality. The imaginaries are associated with a series of situations that can lead the child and adolescent to be linked to this activity (familism, school dropout, scant support from the public institutions, the neoliberal system, consumerism). The prevention centers carry out interventions in daily spaces and promote instances of occupational participation, meanwhile in closed centers are carried out mainly, activities focused on social and labor reintegration.discussionThere is a diversity of perspectives regarding to the interventions, existing significant differences between imaginaries of those occupational therapist who work in contexts of sanctioned population and those who do not. The government limitations greatly restrict the interventions, expectations and projections, confronting this imaginaries with the proposed in the international convention of The Right of the Child.

Molecularly imprinted polymers provide an excellent platform for the modification of selective electrodes for sensing applications. Herein, we present a novel modified carbon paste electrode (CPE) with a selective molecularly imprinted polymer (MIP) for recognition of sesquiterpene ß-caryophyllene, constituted of important plants oil-resins and extracts. The non-covalent MIP was synthesized using AA, EGDMA, and AIBN as a functional monomer, cross-linker and initiator agent, respectively. Structural and chemical characterization of the synthesized MIP was conducted through scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR) spectroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). It was possible to verify the functional features of the synthesized MIP related to the extraction process of the template molecule. The CPE modified with MIP for sesquiterpene ß-caryophyllene recognition was characterized by electrochemical techniques as cyclic voltammetry (CV) and square wave voltammetry (SWV). The highest selective recognition electrode enables to detect concentrations in the range between 1.5â¯×â¯10-7 and 7.5â¯×â¯10-7â¯M, showing great potential for applications in monitoring content of sesquiterpene ß-caryophyllene in technological processes and for predicting the quality of extracts, oils, and resins of plants.

BACKGROUND: Nipple pain is the second most common reason for early weaning, exceeded only by the insufficient milk supply. Nipple fissures can bring other problems, acting also as a portal for bacteria and leading to mastitis. This work proposes the breast protector composite development using materials with tissue repair and moisturizing properties, aligned with a low-cost procedure, aiming not only to relieve pain, but also to heal the nipple fissures caused by breastfeeding. MATERIALS AND METHODS: For the dressings, production was used Natural Latex extracted from the rubber tree and glycerol. The Samples were evaluated chemically and physically by the techniques of Scanning Electron Microscopy, Fourier transform infrared spectroscopy, mechanical traction, and contact angle. The samples were also biologically evaluated by the hemolytic and cytotoxic activity assays. RESULTS: From the physical-chemical assays, the matrix with glycerol has high pore density; the natural latex and glycerol do not covalently interact, indicating that the glycerol can be released; the glycerol addition makes the matrix more elastic but fragile, and increase the wettability. From the biological assays, both materials showed no hemolytic effects; and the cytotoxicity results showed that glycerol did not present cytotoxicity in the fibroblasts, but show a dose-dependent influence in the keratinocytes. CONCLUSION: The material developed for application in breast fissures has mechanical properties similar to those found for materials for dermal applications, present high wettability and pore density. Furthermore, the material showed no cytolytic activity and the tests with skin cell cultures demonstrated the biocompatibility.
