Octreotide-mediated neurofunctional recovery in rats following traumatic brain injury. Role of H2S, Nrf2 and TNF-α

Acta cir. bras; 36 (12), 2021
ABSTRACT Purpose: To explore the role and mechanisms of octreotide in neurofunctional recovery in the traumatic brain injury (TBI) model. Methods: Rats were subjected to midline incision followed by TBI in the prefrontal cortex region. After 72 hours, the behavioural and neurological deficits tests wer...

Association of homocysteine with ankylosing spondylitis: a systematic review and meta-analysis

Adv Rheumatol; 61 (), 2021
Abstract Background: Hyperhomocysteinemia is associated with autoimmune diseases such as ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA). Current findings regarding plasma/serum homocysteine (HCY) levels in AS patients are inconsistent. This study aims to s...

Current management of fistulizing perianal Crohn's disease based on serum anti-tumor necrosis factor levels and magnetic resonance imaging monitoring

ABSTRACT Perianal fistulizing Crohn's disease (PFCD) is one of the most complex challenges in the colorectal surgery nowadays, because, even with combined clinical and surgical treatment, the rate of healing of the fistulas is approximately 50%. In this context, the monitoring of serum levels of anti-Tum...

Decreased levels of interleukin 27 in the serum of vitiligo patients

An. bras. dermatol; 95 (5), 2020
Abstract Background: Vitiligo is a common skin disorder in which melanocytes are destroyed by auto-reactive immune responses. The loss of melanocytes results in the appearance of depigmented areas in different parts of the body. Cytokines have remarkable roles in the pathogenesis of vitiligo, such as IL...

Evaluation of cell damage and modulation of cytokines TNF-α, IL-6 and IL-10 in macrophages exposed to PpIX-mediated photodynamic therapy

Braz. j. biol; 80 (3), 2020
Abstract Little is known regarding whether photodynamic therapy (PDT)-induced cell death can substantially compromise macrophages (MΦ), which are important cells in PDT-induced immune responses. Here, parameters of PDT-mediated MΦ cytotoxicity and cytokine production in response to protoporphyr...
