Coronavirus disease 2019 (COVID‑19) is currently the major public health problem worldwide. Neutral electrolyzed saline solution that contains reactive chlorine and oxygen species may be an effective therapeutic. In present study, treatment efficacy of intravenous and/or nebulized neutral combined with usual medical care vs. alone was evaluated in ambulatory patients COVID‑19. A prospective, 2‑arm, parallel‑group, randomized, open‑label, multi‑center, phase I‑II clinical trial including 214...

The severity of adenovirus infection or the success adenovirus-vectorized gene therapy largely depends on efficiency viral entry into cells. Various drugs can alter entry. This study evaluated effects dexamethasone, paracetamol, diclofenac, ibuprofen, and ketorolac cells in vitro vivo. SiHa cell cultures pretreated with ketorolac, no drug were exposed to Ad-BGal vector. percentage showing vector was quantified microscopically. In vivo, BALB-C mice for 7 days intravenously (IV) via oral (VO)....

Introduction: Due to the coronavirus pandemic, identifying infected individuals has become key limiting its spread. Virus nucleic acid real-time RT-PCR testing current standard diagnostic method but high demand could lead shortages. Therefore, we propose a detection strategy using one-step nested RT-PCR.
 Methodology: The nucleotide region in ORF1ab gene that greatest differences between human and bat was selected. Primers were designed after sequence. All primers are species-specific...

Rheumatoid arthritis is globally present in about 1% of the population. This autoinflammatory disease modifies connective tissue, causing pain and inflammation joints. Over time, it causes loss joint cartilage bone mass, decreasing patient's quality life. Treatment options now available either give symptomatic alleviation or alter process. Nonetheless, adherence to chronic treatment typically limited due adverse effects. As a result, new therapy approaches, such as systemic administration...

During phase 2 of the COVID-19 pandemic in a Mexican City, informal street vendors (cases) and formal employees (controls) were interviewed. A total 82.6% preferred to expose themselves coronavirus than stop working, compared with 18.4% (adjusted OR = 19.4, 95%CI: 4.6-81.7, p < 0.001).
