Effects of pravastatin on cellular ultrastructure and hemorheology in rats after traumatic head injury

Pravastatin has neuroprotective effects against aging but its role in brain injury remains unclear. This study evaluated the effects of pravastatin on the ultrastructural changes and hemorheological parameters in rats after traumatic brain injury (TBI) of right parietal cortical contusion by a controlled weight-dropping method. There were three groups: (I) Sham operated group; (II) TBI + vehicle (

UBE2D3 is a positive prognostic factor and is negatively correlated with hTERT expression in esophageal cancer

Human telomerase reverse transcriptase (hTERT) is a critical factor in unlimited cell proliferation and immortalization, with numerous studies demonstrating that high expression of hTERT is a poor prognostic factor in various types of cancer. Ubiquitin-conjugating enzyme E2D 3 (UBE2D3) is a member of the E2 family, and participates in the ubiquitin proteasome pathway to regulate basic cellular act

Electrolyte disorders assessment in solid tumor patients treated with anti-EGFR monoclonal antibodies : a pooled analysis of 25 randomized clinical trials

The role of anti-epithelial growth factor receptor monoclonal antibodies (anti-EGFR MoAbs) in treatment-related electrolyte disorders is still controversial. Therefore, we conducted a meta-analysis of published randomized controlled trials (RCTs) to evaluate the incidences and overall risks of all-grade and grade 3/4 electrolyte disorder events. We searched relevant clinical trials from PubMed, EM

Behavioral and neural aspects of serial dependence in facial identity

Den visuella omvärlden kan vara dynamisk och föränderlig vilket skapar otydlighet i sensorisk information. Dessutom genererar hjärnans neurala aktivitet ”brus” som bidrar till denna otydlighet. Trots dessa svårigheter kan det visuella systemet i hjärnan bearbeta denna otydliga information och skapa en kontinuerlig och stabil visuell upplevelse, vilket låter oss navigera i omvärlden med trygghet. EThe visual environment can be dynamic and often changes from one moment to the next, causing sensory input to be noisy and uncertain. In addition, internal noise from neural activity in the brain contributes to this uncertainty. Despite these challenges, the brain’s visual system adeptly processes this noisy and uncertain information, creating a stable and continuous perceptual experience that all

Micro ct analysis of sellar floor in pituitary adenomas, especially in Cushing's disease

Context. The aim of this study was to explore the prognostic significance correlation between the endocrinopathy and the size of the pituitary adenoma with the sellar floor bone mineral density values using microfocus computerized tomography (μCT) analysis. Subjects and Methods. 16 consecutive patients with pituitary adenomas had full endocrinological and radiological work up prior to endoscopic t

Soft tissue response to the presence of polypropylene-g-poly(ethylene glycol) comb-type graft copolymers containing gold nanoparticles

The aim of this study is to evaluate the soft tissue response of the pure and Au-embedded PPg-PEG. PP-g-PEG2000, PP-g-PEG4000, Au-PP-g-PEG2000, and AuPP-g-PEG4000 were obtained via chlorination of polypropylene and polyethylene glycol in the presence of a base with a "grafting onto" technique. Solvent cast films of these four copolymers with PP as a control group were embedded into five different

Isolated paralysis of glossopharyngeal and vagus nerve associated with type II occipital condyle fracture : Case report

Introduction: Occipital condyle fractures (OCFs) can occasionally be complicated with lower cranial nerve palsies. Discussion: Isolated 9th and 10th cranial nerve palsies following OCF are very rare. To our knowledge, we report the first case of an early onset of 9th and 10th cranial nerve palsies with an early full recovery in short period of time and discuss the probable mechanism of isolated ne

Predictive value of excision repair cross-complementation group 1 expression for platinum-based chemotherapy and survival in gastric cancer : a meta-analysis

PURPOSE: The predictive value of excision repair cross-complementation group 1 (ERCC1) gene for survival and response to platinum-based chemotherapy in gastric cancer (GC) remains controversial. We performed a meta-analysis to clarify the precise estimation of the prognostic and predictive effect of ERCC1.METHODS: A systematic literature search was conducted using PubMed, ScienceDirect, Wiley and

The age-dependent association of risk factors with pancreatic cancer

BACKGROUND: Pancreatic cancer presents as advanced disease in >80% of patients; yet, appropriate ages to consider prevention and early detection strategies are poorly defined. We investigated age-specific associations and attributable risks of pancreatic cancer for established modifiable and non-modifiable risk factors.PATIENTS AND METHODS: We included 167 483 participants from two prospective US

Plasma 25-Hydroxyvitamin D Levels and Survival in Stage III Colon Cancer : Findings from CALGB/SWOG 80702 (Alliance)

PURPOSE: To assess whether higher plasma 25-hydroxyvitamin D [25(OH)D] is associated with improved outcomes in colon cancer and whether circulating inflammatory cytokines mediate such association.EXPERIMENTAL DESIGN: Plasma samples were collected from 1,437 patients with stage III colon cancer enrolled in a phase III randomized clinical trial (CALGB/SWOG 80702) from 2010 to 2015, who were followed

Treatment of acromegaly by endoscopic transsphenoidal surgery : Surgical experience in 214 cases and cure rates according to current consensus criteria - Clinical article

Object. Acromegaly is a disease that has significant morbidity and mortality related to high levels of growth hormone (GH) and insulin-like growth factor-I (IGF-I), and is usually caused by pituitary adenomas. The goal in this study was to investigate the role of endoscopic transsphenoidal surgery and surgical experience in the treatment of GH adenoma cases in relation to surgical results and horm

The efficacy of silver-embedded polypropylene-grafted polyethylene glycol-coated ventricular catheters on prevention of shunt catheter infection in rats

Purpose: Catheter-related infection is a major complication of ventriculoperitoneal shunt in children. The aim of this study is to determine inflammatory response and the efficacy of polypropylene-grafted polyethylene glycol (PP-g- PEG) copolymer and silver nanoparticle-embedded PP-g- PEG (Ag-PP-g-PEG) polymer-coated ventricular catheters on the prevention of catheter-related infections on a new e

Peripheral nerve

In order to understand peripheral nerve dysfunction, and to follow neuronal regeneration, basic sciences of the peripheral nerve should be understood completely. A surgeon who operates on "nerves" uses this knowledge, especially the organization of the peripheral nerve, in nerve reconstructions. When a nerve has been injured, the goal of surgical repair is generally to reapproximate the ends of th

Complications of endoscopic surgery of the pituitary adenomas : Analysis of 570 patients and review of the literature

Endoscopic transsphenoidal surgery is emerging as a minimally invasive and maximally effective procedure for pituitary adenomas. In this report we analyzed the complications in 624 procedures of endonasal transsphenoidal endoscopic surgery in the treatment of 570 patients with pituitary adenomas. The leading author (MB) operated pituitary adenomas via pure endoscopic endonasal transsphenoidal surg

Synthesis of microbial elastomers based on soybean oil. Autoxidation kinetics, thermal and mechanical properties

Microbial bioelastomers prepared by the autoxidation of the unsaturated medium-long chain length copoly- 3-hydroxyalkanoate's (mlcl-PHAs) based on soybean oily acids (Sy) have been reported. Pseudomonas oleovorans were grown on a series of the mixture of octanoic acid (OA) and Sy with the weight ratio of 20:80, 28:72 and 50:50 in order to obtain unsaturated mlcl-copolyesters coded PHO-Sy-2080, PHO
