1. Como é feito o diagnóstico laboratorial da infecção pelo HIV?
De acordo com recomendações do Ministério da Saúde, as amostras de soro ou plasma devem inicialmente ser submetidas a um imunoensaio, denominado Elisa (“teste 1″ – capaz de identificar tanto anti-HIV-1 quanto anti-HIV-2), na etapa denominada triagem sorológica.
As amostras com resultados não-reagentes no “teste 1″ serão definidas co

2. Dexmedetomidine Leads to the Mitigation of Myocardial Ischemia/Reperfusion-Induced Acute Lung Injury in Diabetic Rats Via Modulation of Hypoxia-Inducible Factor-1α
ABSTRACT Introduction: The objective of this study is to investigate the protective mechanism of dexmedetomidine (Dex) in myocardial ischemia/reperfusion (MIR)-induced acute lung injury (ALI) of diabetic rats by inhibiting hypoxia-inducible factor-1α (HIF-1α). Methods: Initially, healthy male Sprague Dawley rats were treated with streptozocin to induce d

3. EFFECT OF MERCURY EXPOSURE ON U1-70 KDA PROTEIN EXPRESSION IN EMBRYOS OF BLACK BEAN (Phaseolus vulgaris L.)
Exposure to heavy metals has been documented to induce changes in the expression of plant proteins. Phaseolus vulgaris L., represents a great source of nutrition for millions of people, and is the second most important legume crop. The present study aimed to investigate the effects of Hg stress on germination rate and identify the gene expression profiling o

5. Changes in gap junction proteins Connexin30.2 and Connexin40 expression in the sinoatrial node of rats with dexmedetomidine-induced sinus bradycardia
Abstract Background Dexmedetomidine (Dex) is widely used, and its most common side effect is bradycardia. The complete mechanism through which Dex induces bradycardia has not been elucidated. This research investigates the expression of gap junction proteins Connexin30.2 (Cx30.2) and Connexin40 (Cx40) within the sinoatrial node of rats with Dex-induced sinu

6. Effect of crosstalk between Th17 and Th9 cells on the activation of dermal vascular smooth muscle cells in systemic scleroderma and regulation of tanshinone IIA
Abstract Background: To evaluate the effect of T-helper 17 (Th17) cells and Th9 cells on the activation of dermal vascular smooth muscle cells (DVSMCs) in systemic scleroderma (SSc) and regulation of tanshinone IIA. Methods: The expression of interleukin 17 receptor (IL-17R) and interleukin 9 receptor (IL-9R) in the skin of SSc patients was assessed by imm

7. Analgesia with 5' extracellular nucleotidase-mediated electroacupuncture for neuropathic pain
RESUMO Antecedentes: A acupuntura é um tratamento para a dor neuropática, mas seu mecanismo permanece obscuro. Estudos anteriores mostraram que a analgesia foi induzida em ratos com dor neuropática quando o conteúdo de adenosina da medula espinhal aumentou após a eletroacupuntura (EA); no entanto, o mecanismo por trás desse aumento induzido por eletro

8. MicroRNA-124a Protects the Myocardium Against Ischemia Reperfusion Injury Through Regulation of the Notch Signaling Pathway
Abstract Introduction: This study’s objective is to investigate the effect of downregulation of micro ribonucleic acid (miR)-124a on myocardial injury after ischemia reperfusion (I/R) in rats. Methods: Sprague Dawley (SD) rats (n=20) were divided into four groups - sham, I/R, I/R+miR-124a antagomir (I/R+ant-miR-124a), and I/R+ant-normal control (NC). The

12. Study on the mechanism and therapeutic effect of Antelope horn treatment on cerebral ischemia reperfusion injury of mouse
Abstract To the mechanism and therapeutic effect of Antelope horn treatment on cerebral ischemia reperfusion injuries under different levels of concentration. The process is as follows: (1) establish MCAO mouse model, test the modelling using traction and open field experiments, use TTC staining to detect the protective effect of Antelope horn treatment on c
