Background And Aims: Rectal prolapse (RP) is a debilitating condition and can cause symptoms of fecal incontinence, obstructed defecation, incomplete evacuation of the rectum, and pain. In recent years, there has been increasing evidence that prolapse development is strongly associated with pelvic hiatus (GH) size (normal 4.5 +/- 0.

Colorectal operations are amongst the most frequently performed surgical procedures worldwide. Success of colorectal surgery is significantly influenced by occurrence of postoperative complications; Efforts are directed in detecting risk factors for these complications and trials to avoid risk factors to reduce complications rate. This study was conducted to assess the impact of mechanical bowel preparation in preventing post-operative anastomotic leakage in adult patients undergoing elective restorative colorectal surgery.

Type 1 diabetes mellitus (T1DM) refers to a metabolic condition where a lack of insulin impairs the usual homeostatic mechanisms to control blood glucose levels. Historically, participation in competitive sport has posed a challenge for those with T1DM, where the dynamic changes in blood glucose during exercise can result in dangerously high (hyperglycaemia) or low blood glucoses (hypoglycaemia) levels. Over the last decade, research and technological development has enhanced the methods of monitoring and managing blood glucose levels, thus reducing the chances of experiencing hyper- or hypoglycaemia during exercise.

Background: Sport-related concussion (SRC) remains an injury of concern in sport, including football(soccer). There has been little investigation into SRC knowledge and attitudes of support staff working in the professional setting.

Methods: An amended version of the Rosenbaum Concussion Knowledge and Attitudes Survey(RoCKAS) was distributed online to coaching staff, and medical and performance staff, working at clubs in the English Football Association Women's SuperLeague (WSL) and Championship.

Flurbiprofen (FP) is one of the non-steroidal anti-inflammatory drugs (NSAIDs) commonly used to treat arthritic conditions. FP has two enantiomers: S-FP and R-FP. S-FP has potent anti-inflammatory effects, while R-FP has nearly no such effects.

Hepatocellular carcinoma (HCC) is a growing health concern projected to cross over a million cases worldwide by 2025. HCC presents a significant burden of disease in Middle East and North African (MENA) countries due to a high prevalence of risk factors such as hepatitis C and B infections and rising incidence of non-alcoholic steatohepatitis and non-alcoholic fatty liver disease. In August 2022, an advisory meeting consisting of experts from 5 MENA countries was convened in an attempt to provide consensus recommendations on HCC screening, early diagnosis, current treatment modalities and unmet medical needs in the region.

Mesenchymal-epithelial transition exon 14 (METex14) skipping mutations occur in about 3%-4% of patients with non-small cell lung cancer (NSCLC). This is an aggressive subtype associated with poor prognosis. METex14 skipping is a potentially targetable mutation.

Purpose: We aimed to assess the clinical and radiological outcomes of a modified anatomical posterolateral corner (PLC) reconstruction technique using a single autograft.

Methods: This prospective case series included 19 patients with a posterolateral corner injury. The posterolateral corner was reconstructed using a modified anatomical technique that utilized adjustable suspensory fixation on the tibial side.

Background And Study Aims: Gastroparesis is a well-known consequence of long-standing diabetes that presents with gastric dysmotility in the absence of gastric outlet obstruction. This study aimed to evaluate the therapeutic effects of mosapride and levosulpiride on improving gastric emptying in type 2 diabetes mellitus (T2DM) while regulating glycemic levels.

Material And Methods: Rats were divided into the normal control, untreated diabetic, metformin-treated (100 mg/kg/day), mosapride-treated (3 mg/kg/day), levosulpiride-treated (5 mg/kg/day), metformin (100 mg/kg/day) + mosapride (3 mg/kg/day)-treated, and metformin (100 mg/kg/day) + levosulpiride (5 mg/kg/day)-treated diabetic groups.

RNA epigenetics has emerged as an active topic to study gene regulation mechanisms. In this regard, the MeRIP-seq technology allows profiling transcriptome-wide mRNA modifications, in particular mA. The primary goals for the analysis of MeRIP-seq data are the identification of mA-methylated regions under each condition and across different biological conditions.

Background: Sport-related concussions (SRC) are more common and more severe in women's football than men's yet the knowledge and attitudes of SRC in the women's game are not well understood. The objective of this study was to assess the SRC knowledge and attitude in elite female footballers.

Methods: An online questionnaire was sent to all registered players in the English Football Association Women's Super League (WSL) and Championship.

The mechanisms by which environmentally-induced epiphenotypes are transmitted transgenerationally in mammals are poorly understood. Here we show that exposure of pregnant mouse females to bisphenol A (BPA) results in obesity in the F2 progeny due to increased food intake. This epiphenotype can be transmitted up to the F6 generation.

Motivation: RNA epigenetics is an emerging field to study the post-transcriptional gene regulation. The dynamics of RNA epigenetic modification have been reported to associate with many human diseases. Recently developed high-throughput technology named Methylated RNA Immunoprecipitation Sequencing (MeRIP-seq) enables the transcriptome-wide profiling of N6-methyladenosine (m6A) modification and comparison of RNA epigenetic modifications.

Distinct cell types are generated at specific times during brain development and are regulated by epigenetic, transcriptional, and newly emerging epitranscriptomic mechanisms. RNA modifications are known to affect many aspects of RNA metabolism and have been implicated in the regulation of various biological processes and in disease. Recent studies imply that dysregulation of the epitranscriptome may be significantly associated with neuropsychiatric, neurodevelopmental, and neurodegenerative disorders.

Aims: Cardiac affection is common in diabetic patients. Although insulin exerts a cardioprotective role, it may not be enough to totally prevent this affection. The current study aimed to compare the cardioprotective effect of insulin alone or combined with sitagliptin in a rat model of type 1 diabetes mellitus.

In the present work, the acid dyes namely, eriochrome cyanine R (ECR) and 2-(4-Sulfo phenyl azo)-1,8 dihydroxy-3,6 naphthalene disulfonic acid, trisodium salt (SPADNS) were effectively adsorbed by Cu(II)-thiourea modified cotton fibers (Cu(II)/Tu-MC) complex. FTIR, SEM, XPS analysis, thermogravimetric analysis, and potentiometric titration were utilized for characterization. The impact of the fundamental adsorption parameters was systematically investigated.

RNA modifications affect many aspects of RNA metabolism and are involved in the regulation of many different biological processes. Mono-methylation of adenosine in the N1 position, N1-methyladensoine (m1A), is a reversible modification that is known to target rRNAs and tRNAs. m1A has been shown to increase tRNA structural stability and induce correct tRNA folding.

Mapping the position and quantifying the level of 5-methylcytosine (mC) as a modification in different types of cellular RNA is an important objective in the field of epitranscriptomics. Bisulfite conversion has long been the gold standard for the detection of mC in DNA, but it can also be applied to RNA. Here, we detail methods for bisulfite treatment of RNA, locus-specific PCR amplification, and detection of candidate sites by sequencing on the Illumina MiSeq platform.
