Aim: The aim of this study was to compare the effects dexmedetomidine, midazolam, propofol, and intralipid on lidocaine-induced cardiotoxicity neurotoxicity. Methods: Forty-eight male Sprague-Dawley rats were randomly divided into six groups (n = 8 per group): control (C), lidocaine (L), + dexmedetomidine (LD), midazolam (LM), propofol (LP), (LI). Dexmedetomidine (100 μg/kg), (4 mg/kg), (40 (10 mg/kg) administered intraperitoneally as pretreatment. Lidocaine (90 induce oxidative stress in...

BACKGROUND Ligamentum flavum (LF) hypertrophy is a key contributor to spinal pathologies such as lumbar and cervical disc herniations stenosis. Smoking, modifiable lifestyle factor, implicated in systemic inflammation oxidative stress, potentially exacerbating LF hypertrophy. This study aimed compare the expression of alpha-1 antitrypsin (AAT), interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) ligamentum from 27 smokers 31 non-smokers. MATERIAL AND...

<title>Abstract</title> Background Spontaneous subarachnoid hemorrhage (SAH) is a severe neurological condition with significant morbidity and mortality. Cerebral vasospasm, common complication of SAH, leading cause delayed ischemic injury. Oxidative stress inflammation are central to the pathophysiology vasospasm. Vitamin B12, water-soluble vitamin antioxidant anti-inflammatory properties, has shown potential neuroprotective effects in experimental models. Objectives This study aimed...

Abstract Intro : Thymoquinone(TQ), a compound derived from Nigella sativa , has been found to impede cancer progression, including proliferation, migration, and invasion. Previous research explored the potential benefits of augmenting TQ with functional groups enhance its activity, particularly when combined traditional drugs. The aim our study was investigate therapeutic effects Thymoquinone‐Oxime(TQ−Ox) on lung cell lines. Methods To determine structure novel TQ−Ox substance, we employed...

Abstract Multiple sclerosis (MS) is a demyelinating nervous system disease known for its lesions and manifests itself with attacks. According to some theories, inflammation oxidative stress play an important role in MS. With this study, we aimed examine the levels of stress, DNA damage MS patients get idea about course from these data. The research comprised diagnosed between ages 18 60. Photometric techniques were used determine serum native thiol (NT), total (TT), antioxidant status (TAS),...
