1. Biomarker potential of hsa-miR-145-5p in peripheral whole blood of manic bipolar I patients
Objective: Bipolar I disorder (BD-I) is a type of bipolar spectrum disorder characterized by manic or mixed episodes. Detecting microRNA regulations as epigenetic actors in BD-I is important to elucidate the pathogenesis of the disease and reveal the potential of microRNAs (miRNAs) as biomarkers. Methods: We evaluated the expression profile of six candidate

3. Blood microRNA expressions in patients with mild to moderate psoriasis and the relationship between microRNAs and psoriasis activity,
Abstract Background: In recent studies, microRNAs (mi-RNAs) have been shown to play an important role in psoriasis pathogenesis. However, studies evaluating mi-RNAs in the blood of psoriasis patients including a large number of mi-RNA panels are scarce. Objective: The authors aimed to assess mi-RNA expressions in blood samples of psoriasis patients, as wel

4. Synthesis, Characterization, Spectroelectrochemical, Photophysical and HSA-Binding Properties of Novel and Versatile meso-Tetra(4-pyridylvinylphenyl)porphyrins Coordinated to Ruthenium(II)-Polypyridyl Derivatives
The free-base meso-tetra(4-pyridylvinylphenyl)porphyrin (1a) and its zinc(II) complex were synthesized and then functionalized with [Ru(bpy)2Cl]+ units (2a and 2b) via conventional methods and evaluated in terms of photophysical, electrochemical and biological aspects. All porphyrins present moderate singlet oxygen production and fluorescence quantum yield,

5. Antibacterial Activity of 2-Amino-1,4-naphthoquinone Derivatives against Gram-Positive and Gram-Negative Bacterial Strains and Their Interaction with Human Serum Albumin
A series of 2-amino-1,4-naphthoquinone derivatives (NQA-NQF) was synthesized by alternative methods (ultrasonication and microwave irradiation), with yields ranging from 40 to 71%, and without the need of further recrystallization. Each compound was evaluated against four Gram-positive (Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus and Baci

6. INTERAÇÕES COMPETITIVAS DE COMPLEXOS DE RUTÊNIO CONTENDO DIMETILSULFÓXIDO E LIGANTES N-HETEROCÍCLICOS COM ALBUMINA DE SORO HUMANO
Two ruthenium complexes of the type [RuCl(dmso)(L)2]Cl {L = 4,4’-dimethyl-2,2’-bipyridine (dmbpy); 4,4’-dinonyl-2,2’-bipyridine (dnbpy)} have been synthesized and characterized by elemental analysis, 1H NMR, FTIR, electronic spectra, and molar conductivity. The IR spectral studies revealed that the DMSO molecule is S-bound ( νSO= 1100 cm-1; 1079 cm-

7. Aneurysmal subarachnoid hemorrhage: current concepts and updates
RESUMO Hemorragia subaracnoidea aneurismática (aHSA) é uma condição com grande variação de incidência mundialmente. No Brasil, não dispomos de números epidemiológicos exatos. A apresentação clínica mais comum da HSA é a cefaleia, usualmente descrita como a pior da vida. A tomografia de crânio, quando feita nas primeiras 6 horas do ictus, tem u

8. Design, Synthesis, Trypanocidal Activity, and Studies on Human Album in Interaction of Novel S-Alkyl-1,2,4-triazoles
Chagas disease is a neglected tropical disease caused by the hemoflagellated parasite Trypanosoma cruzi (Kinetoplastida). The only available drug to treat chagasic patients in Brazil, the nitroheterocycle benznidazole, is effective solely during the acute phase of the infection. There is accordingly a need to develop new therapeutic tools for the treatment o

9. Human sapovirus GI.2 and GI.3 from children with acute gastroenteritis in northern Brazil
Human sapoviruses (HSaV) are considered important causative agents of acute gastroenteritis in humans worldwide. However, knowledge of the genetic characteristics of the whole genome of HSaV in Brazil is limited. Here we report the complete genome sequences of six HSaVs GI.2 and two GI.3 strains obtained from children with acute gastroenteritis in the Northe

10. ELUCIDAÇÃO DA QUIRALIDADE INDUZIDA NA MOLÉCULA DANSILGLICINA NA COMPLEXAÇÃO COM A PROTEÍNA ALBUMINA DO SORO HUMANO (HSA)
Human serum albumin (HSA) plays an important role in the transport of a wide variety of substances, including compounds with pharmacological properties. The dansylglycine (DanG) is a fluorescent amino acid derivative specific for the site II of HSA. This work aimed to elucidate the induction of chirality in the DanG due to its bonding to the HSA. Theoretical

11. Anti-ophidian activity of Bredemeyera floribunda Willd. (Polygalaceae) root extract on the local effects induced by Bothrops jararacussu venom
Bredemeyera floribunda roots are popularly used to treat snakebites in the semiarid region of Northeast Brazil, and previous studies indicate the anti-ophidian actions of triterpenoid saponins found in its roots. To assess B. floribunda root extract (BFRE) activity against the effects of Bothrops jararacussu venom (BjuV), antiphospholipasic, antiproteolytic,

12. Circular RNA hsa_circ_0000523 regulates the proliferation and apoptosis of colorectal cancer cells as miRNA sponge
Among the novel class of endogenous long non-coding RNAs, circular RNA (circRNA) is known as a key regulator in the development and progression of different cancers. Its function and mechanism in the tumorigenesis of colorectal cancer, however, has not been well studied. This study thus aimed to investigate potential regulation of colorectal cancer by circRN
