Identification of a Novel hsa_circ_0058058/miR-324-5p Axis and Prognostic/Predictive Molecules for Acute Myeloid Leukemia Outcome by Bioinformatics-Based Analysis.

Acute myeloid leukemia (LAML) is one of the most prevalent hematological malignancies. In recent years, while targeted approaches have shown promise in the fight against cancer, the treatability and prognosis of patients remain inadequate due to the shortage of drugs. Noncoding RNAs, especially circular RNA (circRNA) and microRNA (miRNA), have been shown to play a unique role in tumor development.

MicroRNA networks linked with BRCA1/2, PTEN, and common genes for Alzheimer's disease and breast cancer share highly enriched pathways that may unravel targets for the AD/BC comorbidity treatment.

MicroRNAs (miRNAs) are involved in the regulation of various cellular processes including pathological conditions. MiRNA networks have been extensively researched in age-related degenerative diseases, such as cancer, Alzheimer's disease (AD), and heart failure. Thus, miRNA has been studied from different approaches, in vivo, in vitro, and in silico including miRNA networks.

The role of human milk nutrients in preventing necrotizing enterocolitis.

Necrotizing enterocolitis (NEC) is an intestinal disease that primarily impacts preterm infants. The pathophysiology of NEC involves a complex interplay of factors that result in a deleterious immune response, injury to the intestinal mucosa, and in its most severe form, irreversible intestinal necrosis. Treatments for NEC remain limited, but one of the most effective preventative strategies for NEC is the provision of breast milk feeds.

Fascicles split or merge every ∼560 microns within the human cervical vagus nerve.

Vagus nerve stimulation (VNS) is Food and Drug Administration-approved for epilepsy, depression, and obesity, and stroke rehabilitation; however, the morphological anatomy of the vagus nerve targeted by stimulatation is poorly understood. Here, we used microCT to quantify the fascicular structure and neuroanatomy of human cervical vagus nerves (cVNs).We collected eight mid-cVN specimens from five fixed cadavers (three left nerves, five right nerves).

Dual function miR-205 is positively associated with ER and negatively with five-year survival in breast cancer patients.

Background: Precise molecular characterization of breast cancer, especially triple negative (TNBC) as the most lethal subtype, is needed to stratify patients for the individual treatment approach. MicroRNA-205 (miR-205) has tumor-suppressive and oncogenic functions across different cancers. Therefore, miR-205 might have a different role in TNBC and estrogen receptor (ER) positive BC.

Inflammation, microbiome and colorectal cancer disparity in African-Americans: Are there bugs in the genetics?

Dysregulated interactions between host inflammation and gut microbiota over the course of life increase the risk of colorectal cancer (CRC). While environmental factors and socio-economic realities of race remain predominant contributors to CRC disparities in African-Americans (AAs), this review focuses on the biological mediators of CRC disparity, namely the under-appreciated influence of inherited ancestral genetic regulation on mucosal innate immunity and its interaction with the microbiome. There remains a poor understanding of mechanisms linking immune-related genetic polymorphisms and microbiome diversity that could influence chronic inflammation and exacerbate CRC disparities in AAs.

Prognostic impact of miR-34b/c DNA methylation, gene expression, and promoter polymorphism in HPV-negative oral squamous cell carcinomas.

Micro RNAs (miRNAs) have a key role in gene expression regulation in cancer. The aim of the current study is to evaluate the prognostic value of miR-34b/c promoter hypermethylation, gene expression, and polymorphism in HPV-negative oral squamous cell carcinomas (OSCC). MiR-34b/c promoter hypermethylation and pre-miR-34b/c polymorphism rs4938723 were evaluated in tumor tissues of 148 patients, and miR-34b expression in 123 HPV-negative OSCC.

Dual Biologic Therapy in an Adolescent With Camurati-Engelmann Disease and Crohn Disease.

Camurati-Engelmann disease (CED) is a rare disorder caused by activating mutations in the TGF-β1 gene and characterized by hyperostosis of long bones and bone dysplasia. We describe a case of an adolescent with CED and moderate-severe Crohn Disease (CD). Infliximab improved gastrointestinal symptoms but was associated with worsening CED-associated bone pain.

Gene Expression Profiles Reveal Extracellular Matrix and Inflammatory Signaling in Radiation-Induced Premature Differentiation of Human Fibroblast .

Purpose: Fibroblasts are considered to play a major role in the development of fibrotic reaction after radiotherapy and premature radiation-induced differentiation has been proposed as a cellular basis. The purpose was to relate gene expression profiles to radiation-induced phenotypic changes of human skin fibroblasts relevant for radiogenic fibrosis.

Materials And Methods: Exponentially growing or confluent human skin fibroblast strains were irradiated with 1-3 fractions of 4 Gy X-rays.

The correlation between vitamin D levels and demographics in patients with gastrointestinal disorders; a cross-sectional study.

Aim: The aim of the present study was to evaluate vitamin D levels, in correlation with age, body mass index (BMI), gender and ethnicity, in patients with gastrointestinal disorders (GID).

Background: Vitamin D deficiency (VDD) is a global health issue, affecting over 1 billion people. A great body of evidence has shown that it can lead to increased morbidity and mortality.

Citation classics in general medical journals: assessing the quality of evidence; a systematic review.

Aim: This review provides a comprehensive overview of more than 100 of the most cited studies in general medical journals and evaluates whether citations predict the quality of a scientific article.

Background: The number of citations is commonly used as a measure of the quality and impact of a scientific article. However, it is often criticised that the number of citations is in fact a poor indicator of the true quality, as it can be influenced by different factors such as current trends.

Serum Proteome Profiling to Identify Proteins Promoting Pathogenesis of Non-atopic Asthma.

Background: Asthma is the inflammatory disorder of airways highly prevalent in both, children and adults all over the world. The aim of this study was to investigate the serum proteome for the identification of proteins contributing to the pathogenesis of non-atopic asthma.

Methods: Protein expression profiling of sera from non-atopic asthmatic patients (n=73) and controls (n=99) was carried out using 1D SDS PAGE.

Gallbladder perforation into the greater omentum following sleeve gastrectomy: A case report study.

Introduction: Obesity is considered a major risk factor for gallstone formation and is important due to its increasing prevalence worldwide. Many studies have reported an increased incidence of gallstone formation following bariatric surgery. This report documents a rare case of a complicated cholecystitis following sleeve gastrectomy and describes our management of the case and the management options for gallbladder disease in bariatric patients.

TIMP-3 mRNA expression levels positively correlates with levels of miR-21 in in situ BC and negatively in PR positive invasive BC.

Background: Breast carcinomas (BC) belong to a heterogeneous group of malignant diseases. Correct categorization of BC based on molecular biomarkers has a very important role in deciding the proper course of therapy for each patient. It has been already shown that the decrease of TIMP metalloproteinase inhibitor 3 (TIMP-3) together with overexpression of microRNA-21 (miR-21) might be involved in the process of BC invasion.

The hundred most cited articles in bariatric surgery.

Background: Many studies quantitatively analyzing scientific papers have appeared in the last 2 years. Citation analysis is a commonly used bibliometric method. In spite of some limitations, it remains a good measure of the impact an article has on a specific field, specialty, or a journal.
