Isolation and Biological Evaluation of Triterpenes from Leaves.

is naturally found in the Atlantic Forest regions of Brazil. Despite the pharmacological potential of plants from the genus, phytochemical studies on this species have not been reported in literature. A new triterpene, 28-hydroxyfriedelane-3,15-dione (), and seven known compounds (friedelan-3-one (), friedelan-3β-ol (), friedelane-3,15-dione (), 15α-hydroxyfriedelan-3-one (), 28-hydroxyfriedelan-3-one (), 30-hydroxyfriedelan-3-one (), and 29-hydroxyfriedelan-3-one ()) were obtained from the hexane extract of leaves.

Brazilian portuguese validation of the patient-reported outcome measure for urethral stricture surgery (USS-PROM) questionnaire.

Introduction: Urethral stricture is a common, albeit complex, condition that predominantly affects men. The aim of this study was to translate, culturally adapt, and validate the Patient-Reported Outcome Measure questionnaire for patients undergoing urethroplasty (USS-PROM) into Brazilian Portuguese using validated psychometric criteria.

Materials And Methods: The process involved translating and culturally adapting the original USS-PROM into Brazilian Portuguese (USS-PROMbr), synthesizing, back-translating, cross-culturally adapting, and analyzing the pre-final version with experts from our committee.

Skeletal Muscle Discomfort and Lifestyle of Brazilian Military Police Officers of Administrative and Tactical Force.

Our aim was to evaluate musculoskeletal discomfort and the lifestyle of military police officers of administrative and tactical force departments. Military police officers were distributed into two groups: administrative (Adm, = 15) and tactical force (TF, = 16) departments. Their lifestyle was assessed using the Fantastic Lifestyle questionnaire.

Application of spatial environmental indicators in the assessment of degradation potential of water resources in water basins.

Changes in land use have been occurring in a continuous and disorderly way in recent decades due to rapid population growth and the growing demand for food. These constant changes result in a series of harmful effects to the environment, especially to water resources, significantly changing their availability and quality. This study aims to evaluate the degradation potential of watersheds through an evaluation of some environmental indicators using arithmetic means to construct an index called in this research "index of potential environmental degradation" (IPED).

Influence of the Dose and Frequency of Administration of Tramadol on Analgesia, Hematological, Biochemical Parameters, and Oxidative Status of Cats Undergoing Ovariohysterectomy.

This study aimed to evaluate the effects of the repeated administration of tramadol subcutaneously on postoperative analgesia, liver, kidneys, and oxidative status in the postoperative period of cats undergoing ovariohysterectomy. Thirty-seven cats were randomly assigned to 5 groups, according to the postoperative analgesic treatment: NaCl 0.9%, GC; tramadol at 2 mg/kg, T2B (q12h) and T2T (q8h); or 4 mg/kg, T4B (q12h) and T4T (q8h).

Effect of maternal true combined endodontic-periodontal lesion on insulin and inflammatory pathway in adult offspring.

Background: Maternal periodontal disease (PED) and apical periodontitis (AP) are associated insulin resistance (IR), increased tumor necrosis factor-α (TNF-α) levels, and alterations in insulin signaling (IS) in the gastrocnemius muscle (GM) of adult offspring. TNF-α stimulates I kappa B kinase (IKK) and c-Jun N-terminal protein kinase (JNK), resulting in IS attenuation. However, studies that investigated the maternal true endodontic-periodontal lesion (EPL) in offspring are scarce, and in this case, the impact could be even higher.

Kinetic, thermodynamic and physical-chemical study of the removal of copper from cachaça using coconut fibers.

The use of coconut fiber as a copper adsorbent in cachaça was optimised, and changes in the chemical quality of the beverage were observed by analytical techniques. The influence of the adsorbent mass and copper concentration parameters was investigated using the Central Composite Design, and the optimum condition was obtained through the use of Response Surface Methodology. The equilibrium of the adsorption reaction was obtained within 120 min.

Polycyclic aromatic hydrocarbons in cachaças packed in bottles of polyethylene terephthalate.

Cachaça is a beverage of great cultural and economic importance for Brazil. It is made up of several substances that are responsible for the flavor of the beverage. Countless substances of a toxic nature can also be present, such as polycyclic aromatic hydrocarbons (PAHs).

Bedside echocardiography to predict mortality of COVID-19 patients beyond clinical data: Data from the PROVAR-COVID study.

Introduction: Cardiac involvement seems to impact prognosis of COVID-19, being more frequent in critically ill patients. We aimed to assess the prognostic value of right ventricular (RV) and left ventricular (LV) dysfunction, evaluated by bedside echocardiography (echo), in patients hospitalized with COVID-19.

Methods: Patients admitted in 2 reference hospitals in Brazil from Jul to Sept/2020 with confirmed COVID-19 and moderate/severe presentations underwent clinical and laboratory evaluation, and focused bedside echo (GE Vivid-IQ), at the earliest convenience, with remote interpretation.

Nonlinear Models to Describe the Testicular Size Growth Curve of Mangalarga Marchador Stallions.

This study aimed to describe the testicular growth curve in Mangalarga Marchador stallions fitting nonlinear models to data of total scrotal width (TSW) and testicular volume (TV). A cross-sectional study was conducted with 120 stallions, aging from 1.75 to 21.

Comparative Study on Lead and Copper Biosorption Using Three Bioproducts from Edible Mushrooms Residues.

Agricultural waste products can be used as biosorbents for bioremediation once they are low-cost and high-efficient in pollutants removal. Thus, waste products from mushroom farming such as cutting and substrate of (popularly known as shiitake) and (also known as champignon) were evaluated as biosorbents for metallic contaminants copper (Cu) and lead (Pb). Shiitake and champignon stalks, and shiitake substrate (medium in which shiitake was cultivated) were dried, grounded, characterized and experimented to remove Cu and Pb from contaminated water.

Long-term objective and subjective outcomes following bilateral implantation of diffractive bifocal or trifocal intraocular lenses.

Objective: To evaluate and compare the objective and subjective outcomes after the bilateral implantation of a diffractive bifocal and trifocal intraocular lens.

Methods: This is a case-control, single-center observational study which included 27 patients; 16 patients were implanted bilaterally with the bifocal AcrySof IQ ReSTOR+3.0D and 11 patients with the trifocal AT LISA tri 839MP.

Clinical variability of the GJB4:c.35G > A gene variant: a study of a large Brazilian erythrokeratodermia pedigree.

Background: Erythrokeratodermas are a heterogeneous group of keratinization disorders. They are inherited in both autosomal dominant and autosomal recessive pattern. Erythrokeratoderma variabilis et progressive (EKVP) is a disorder caused by variations in genes that codify connexins (GJA1, GJB3, GJB4).

A rare case of multiple variants of porokeratosis in the same patient: The clue of dermoscopy for diagnosis and therapeutical update.

Porokeratosis (PK) consists of abnormal keratinization of the epidermis of uncertain etiology and was first described by Mibelli in 1893. Multiple clinical variants of porokeratosis are recognized. The following is a case of a young male who presented more than one form of PK simultaneously.
