1. Natural and Semisynthetic Triterpenes from Combretum leprosum Mart. with Antiplasmodial Activity
Malaria is responsible for thousands of deaths each year. Currently, artemisinin combination therapy (ACT) is used as first-choice medication against the disease. However, the emergence of resistant strains prompts the search for alternative compounds. The present study aimed to investigate the antiplasmodial activities of natural triterpenes (compounds 1 an

2. Association of recurrent upper respiratory tract infections with low production of oxygen intermediates in children
Abstract Objectives: Upper respiratory tract infections in children generally have significant morbidity and mortality. There is little data available about functional immaturity of the immune system and the child’s susceptibility to infections at the beginning of their lives, thus, justifying a more specific immunological analysis. Method: Analysis of h

3. Anti-Zika Virus Effects, Placenta Protection and Chemical Composition of Passiflora edulis Seeds Ethanolic Extract
Various beneficial biological activities have been reported for passion fruit (Passiflora edulis), grown in tropical and subtropical regions. However, no study has yet demonstrated its action against the Zika virus (ZIKV) infection. The present study aimed to investigate the anti-ZIKV of the ethanolic passion fruit seed extract (PFSE), from which, liquid chr

4. The Role of the Immune System on the Cardiac Complications Observed in SARS-CoV-2
Abstract An acute respiratory syndrome caused by SARS-CoV2 was declared a pandemic by the World Health Organization. Current data in the world and in Brazil show that approximately 40% of patients who died have some type of cardiac comorbidity. There are also robust reports showing an increase in IL-6 / IL-1B / TNF-alpha and the presence of lymphopenia in pa

5. Effects of intravenous administration of allogeneic mesenchymal stromal cells, derived from adipose tissue, in five dogs with chronic kidney disease
ABSTRACT Este estudo teve como objetivo avaliar a segurança do tratamento com células estromais mesenquimais alogênicas derivadas do tecido adiposo (aASC) em cães com doença renal crônica (CKD) no momento das infusões e durante o acompanhamento de 120 dias após a última infusão. Cinco cães com CKD receberam três infusões intravenosas de aproxima

6. Maternal exposure to trace cadmium affects gonadal differentiation and development in male offspring rats though a star pathway
Abstract To investigate effect and mechanism of maternal exposure to trace cadmium on the differentiation and development in testis of male offspring rats. Thirty-two pregnant female SD rats were randomly divided into 4 groups: CdCl2 treated group (group A) was intraperitoneally injected with CdCl2 (1.5 mg/kg.d); DES group(group B) was subcutaneously injecte

7. Ricotta whey supplemented with gelatin and collagen for the encapsulation of probiotic lactic acid bacteria
Abstract The aim of the present study was to evaluate the viability of probiotic bacteria Lactobacillus acidophilus (LA-5)® and Bifidobacterium lactis (BB-12)® encapsulation using spray drying (SD) with ricotta whey supplemented with gelatin and hydrolyzed collagen as encapsulating material. Following previous experiments, these gelatin:collagen ratios wer

8. Agro-Industrial Waste Valorization: Transformation of Starch from Mango Kernel into Biocompatible, Thermoresponsive and High Swelling Nanogels
Mango industry processing disposes 40-60% of this fruit as residues, such as peels and kernels. The exploration of bioproducts from these industrial rejects can reduce environmental impact besides of producing high value-added materials. In this scenario, carboxymethyl starch nanoparticles were produced from mango (Mangifera indica L.) kernel starch. These n

9. Allyl Dibenzoylmethane Derivative: Antimelanoma Activity and Study of Its Molecular Mechanism of Interaction with DNA
In this study, we assessed the cytotoxic effect of 1,3-diphenyl-2-allyl-1,3-propanedione (DPAP) on B16F10 and Tm5 melanoma cells and investigated its interaction with DNA (deoxyribonucleic acid) using optical tweezers. The compound showed to be effective against B16F10 cells with selectivity index (SI) of 7.92 and interaction to the outer surface of the doub

10. COVID-19 and adult acute lymphoblastic leukemia: Presentation and management
ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common malignancy in children characterized by the overproduction and accumulation of immature lymphoid cells in the bone marrow and peripheral blood. The BMI-1 is an important component of the Polycomb Repressive Complex-1 (PRC1). It is an important molecule for the self-renewal of hematopo

12. A High Gain Super Wideband Metamaterial Based Antenna
Abstract The paper proposes a high gain, metamaterial based super wideband (SWB) antenna. The SWB antenna has two inverted U slots which are responsible for two notches at 3.5 GHz and 5.5 GHz frequencies. A flower-shaped slot is etched from the radiator to obtain the SWB characteristics. The super wideband antenna has dimensions of 30×35 ×1.5 mm3 with FR4
