1. Nicotine as a Catalyst for Chlorination Promoted by Hypochlorous Acid: Experimental and Theoretical Studies
There is robust evidence of the hypochlorous acid (HClO)-mediated damage in biomolecules, and nicotine boosts the chlorination potency of HClO. We present experimental and theoretical evidence of the mechanism by which nicotine catalyzes the chlorination of pyranine. The rate constants for chlorination of pyranine by HClO were measured in the presence (5.3 �

2. Is there a change in P300 evoked potential after 6 months in cochlear implant users?
Abstract Objective: There are few studies on long-latency auditory evoked potential (P300) in people with hearing loss who use a cochlear implant. Central auditory system evaluation with behavioral and electrophysiological tests is believed to help understand the neuroplasticity mechanisms involved in auditory functioning after cochlear implant surgery. Thi

3. 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

4. Evaluation of platelet indices and pro-inflammatory cytokines in type 2 diabetic patients with retinopathy
SUMMARY OBJECTIVE: The aim of this study was to investigate whether platelet parameters and pro-inflammatory cytokines associated with platelet activation could be surrogate markers of the diabetic retinopathy stages in type 2 diabetic patients. METHODS: This prospective case-control study included 108 type 2 diabetes mellitus patients and 48 healthy contr

5. Tuning the Photocatalytic Activity of Tin Oxide through Mechanical Surface Activation
Tin oxide (SnO2) nanoparticles were synthesized by the co-precipitation method and mechanically modified by high-energy ball milling. The experimental results demonstrate that the collision with zirconia balls produces slight changes in the crystalline, electronic, morphological, and surface properties of SnO2, which lead to an increase in the redox potentia

6. Molecular mechanism of benign biliary stricture inhibition by rosiglitazone-activated peroxisome proliferator-activated receptor gamma
SUMMARY OBJECTIVE: The aim of this study was to investigate whether rosiglitazone-activated peroxisome proliferator-activated receptor gamma can inhibit the occurrence of benign biliary stricture and further elucidate the relevant molecular signaling mechanism. METHODS: The primary cultured rat biliary fibroblasts following experiments were performed using

7. Chronic recalcitrant erythema nodosum leprosum: therapeutic dilemma and role of mycobacterium indicus pranii vaccine
Abstract Erythema nodosum leprosum is a severe immune reaction that complicates the usual course of multibacillary leprosy. There is increased activation of T-cells in erythema nodosum leprosum. Treatment modalities available to date for the management are systemic steroids, thalidomide, methotrexate, cyclophosphamide, azathioprine, minocycline, and apremila

8. Catalytic Effects of Ruthenocene Bimetallic Compounds Derived from Fused Aromatic Ring Ligands on the Main Oxidizing Agent for Solid Rocket Motor
We report the catalytic effect of three ruthenocene bimetallic compounds derived from fused aromatic rings of general formula [{Cp*Ru}2L], with Cp*: pentamethylcyclopentadiene and L = pentalene (1), 2,6-diethyl-4,8-dimethyl-s-indacene (2), and 2,7-diethyl-as-indacene (3), on the thermal decomposition of ammonium perchlorate (AP). The new compound 3 was chara

9. Evaluation of the use of blast furnace slag as an additive in mortars
Abstract Clinker is the raw material used in the manufacture of cement. However, this material is very harmful to the environment, since it is estimated that for every ton of clinker produced, about 1.0 ton of CO2 is released into the atmosphere. For this reason, alternatives were sought for the use of other materials that are less harmful to the environment

10. Update on the pathogenesis of vitiligo
Abstract Vitiligo is a complex disease whose pathogenesis results from the interaction of genetic components, metabolic factors linked to cellular oxidative stress, melanocyte adhesion to the epithelium, and immunity (innate and adaptive), which culminate in aggression against melanocytes. In vitiligo, melanocytes are more sensitive to oxidative damage, lead

11. Morphology Behavior of Copper Films Deposited after Wet Surface Treatment on Polished Alumina
In this paper, a pre-treatment process for electroless copper (Cu) deposition on the polished alumina (Al2O3) 99.9% and the behavior of Cu plating by electroless process after Al2O3 surface treatment were explored. Our work was carried out by changing the roughness of Al2O3 through micro-etching (coarsening), nucleation its surface by a two-step method (sens

12. Caryocar villosum attenuates inflammation by inhibiting CXCL1 activation and peripheral hyperalgesia through opioid pathway modulation
RESUMO O óleo de Caryocar villosum é usado na medicina popular amazônica para tratar dores e condições inflamatórias. Assim, avaliamos as propriedades antiinflamatórias e antinociceptivas do extrato etanólico obtido das cascas dos frutos desta espécie. Os testes de contorções induzidas por ácido acético, hiperalgesia mecânica induzida por carra
