REVIEW
Julian A Gingold, Ndeye-Aicha Gueye, Tommaso Falcone
Patients affected by the presence of leiomyomas may incur a substantial physical, emotional, social and financial toll as well as losses in their quality of life. Although many myomas are not amenable to medical therapy or hysteroscopic resection, many others are amenable to minimally invasive surgical approaches. In patients who prefer to retain their fertility, laparoscopic myomectomy should be considered the intervention of choice. In this review we expand on the surgical techniques of both conventional laparoscopic and robotic-assisted myomectomies...

BACKGROUND: Dual RV has been proposed as an alternative for patients with heart failure undergoing cardiac resynchronization therapy (CRT) with a failure to deliver a coronary sinus (CS) lead. Only short-term haemodynamic and echocardiographic results of Dual RV are available. We aimed to assess the long-term results of Dual-site right ventricular pacing (Dual RV) and its impact on survival. METHODS: Multicentre retrospective assessment of all CRT implants during a 12-year period...

Molecular nitrogen (N2) is cheap and widely available, but its unreactive nature is a challenge when attempting to functionalize it under mild conditions with other widely available substrates (such as carbon monoxide, CO) to produce value-added compounds. Biological N2 fixation can do this, but the industrial Haber-Bosch process for ammonia production operates under harsh conditions (450 degrees Celsius and 300 bar), even though both processes are thought to involve multimetallic catalytic sites. And although molecular complexes capable of binding and even reducing N2 under mild conditions are known, with co-operativity between metal centres considered crucial for the N2 reduction step, the multimetallic species involved are usually not well defined, and further transformation of N2-binding complexes to achieve N-H or N-C bond formation is rare...

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of motoneurons and paralysis. The mechanisms underlying neuronal degeneration in ALS are starting to be elucidated, highlighting disturbances in motoneuron proteostasis. Endoplasmic reticulum (ER) stress has emerged as an early pathogenic event underlying motoneuron vulnerability and denervation in ALS. Maintenance of ER proteostasis is controlled by a dynamic signaling network known as the unfolded protein response (UPR)...

Atrial fibrillation is associated with increased risk for cardioembolic stroke. The risk of cardioembolism is not adequately reduced with the administration of oral anticoagulants, since a number of patients continue to experience thromboembolic events despite receiving anti-thrombotic treatment. Several biomarkers have been proposed to predict cardioembolic stroke in patients with atrial fibrillation. Some of them are already used in the clinical practice, such as D-Dimers, Troponin and brain natriuretic peptide...

Bioinformatics tools are imperative for the in depth analysis of heterogeneous high-throughput data. Most of the software tools are developed by specific laboratories or groups or companies wherein they are designed to perform the required analysis for the group. However, such software tools may fail to capture "what the community needs in a tool". Here, we describe a novel community-driven approach to build a comprehensive functional enrichment analysis tool. Using the existing FunRich tool as a template, we invited researchers to request additional features and/or changes...

Most of the studies about conversion from Mild cognitive impairment (MCI) to dementia have focused on amnestic MCI (aMCI) which is considered a preclinical phase of Alzheimer's disease. The aim of the present study was to identify neuropsychological tools that would best predict conversion from aMCI to dementia. Fifty-five aMCI subjects on the Treviso Dementia Registry were investigated. They underwent a neuropsychological evaluation during their first assessment and again at follow-up. Cox proportional-hazard regression models were created to measure the association between the dependent variable (dementia diagnosis or MCI status maintenance) and the neuropsychological test scores at baseline...

BACKGROUND: The hypermethylated in cancer 1/sirtuin 1 (HIC1/SIRT1) axis plays an important role in regulating the nucleotide excision repair pathway, which is the main oxaliplatin-induced damage-repair system. On the basis of prior evidence that the variable number of tandem repeat (VNTR) sequence located near the promoter lesion of HIC1 is associated with HIC1 gene expression, the authors tested the hypothesis that this VNTR is associated with clinical outcome in patients with metastatic colorectal cancer who receive oxaliplatin-based chemotherapy...

INTRODUCTION: The role of adjuvant chemoradiotherapy in patients with pancreatic adenocarcinoma (PA) is controversial. In this study we aimed to assess the feasibility, disease-free survival (DFS) and overall survival (OS) of adjuvant chemoradiotherapy (gemcitabine based) in patients with resected PA and their correlation with prognostic factors. METHODS: 122 resected patients (stage ≥IIa) treated between February 1999 and December 2013 were analyzed. Two cycles of gemcitabine (1,000 mg/m2 on days 1, 8 and 15 every 28 days) were administered before concomitant radiotherapy (45 Gy/25 fractions) and chemotherapy (gemcitabine 300 mg/m2 weekly)...

REVIEW

Supercritical fluid technologies offer a propitious method for drug discovery from natural sources. Such methods require relatively short processing times, produce extracts with little or no organic co-solvent, and are able to extract bioactive molecules whilst minimising degradation. Supercritical fluid extraction (SFE) provides a range of benefits, as well as offering routes to overcome some of the limitations that exist with the conventional methods of extraction. Unfortunately, SFE-based methods are not without their own shortcomings; two major ones being: (1) the high establishment cost; and (2) the selective solvent nature of CO₂, i...

T helper 17 (TH17) cells are key players in multiple sclerosis (MS), and studies in animal models demonstrated that effector TH17 cells that trigger brain autoimmunity originate in the intestine. We validate in humans the crucial role of the intestinal environment in promoting TH17 cell expansion in MS patients. We found that increased frequency of TH17 cells correlates with high disease activity and with specific alterations of the gut mucosa-associated microbiota in MS patients. By using 16S ribosomal RNA sequencing, we analyzed the microbiota isolated from small intestinal tissues and found that MS patients with high disease activity and increased intestinal TH17 cell frequency showed a higher Firmicutes/Bacteroidetes ratio, increased relative abundance of Streptococcus, and decreased Prevotella strains compared to healthy controls and MS patients with no disease activity...

Preparative electrospray (ES) exploits the acceleration of reactions in charged microdroplets to perform a small scale chemical synthesis. In combination with on-line mass spectrometric (MS) analysis, it constitutes a rapid screening tool to select reagents to generate specific products. A successful reaction in preparative ES triggers a refined microfluidic reaction screening procedure which includes the optimization for stoichiometry, temperature and residence time. We apply this combined approach for refining a flow synthesis of atropine...

Biogenesis of lysosome-related organelles complex-1 (BLOC-1) is a protein complex involved in the formation of endosomal tubular structures that mediates the sorting of protein cargoes to specialised compartments. In this study, we present insights into the metabolic consequences caused by BLOC-1 deficiency in pallid mice, which carry a null mutation in the Bloc1s6 gene encoding an essential component of this complex. The metabolome of the hippocampus of pallid mice was analysed using an untargeted, liquid chromatography-coupled mass spectrometric approach...
