This study aims to clarify the mechanisms underlying transcriptional regulation and regulatory roles of lncRNAs in skeletal muscle cell differentiation.

We analysed the expression patterns of lncRNAs via time-course RNA-seq. Then, we further combined the ATAC-seq and ChIP-seq to investigate the governing mechanisms of transcriptional regulation of differentially expressed (DE) lncRNAs. Weighted correlation network analysis and GO analysis were conducted to identify the transcription factor (TF)-lncRNA pairs related to skeletal muscle cell differentiation.

We identified 385 DE lncRNAs during C2C12 differentiation, the transcription of which is determined by chromatin states around their transcriptional start sites. The TF-lncRNA correlation network showed substantially concordant changes in DE lncRNAs between C2C12 differentiation and satellite cell rapid growth stages. Moreover, the up-regulated lncRNAs showed a significant decrease following the differentiation capacity of satellite cells, which gradually declines during skeletal muscle development. Notably, inhibition of the lncRNA Atcayos and Trp53cor1 led to the delayed differentiation of satellite cells. Those lncRNAs were significantly up-regulated during the rapid growth stage of satellite cells (4-6weeks) and down-regulated with reduced differentiation capacity (8-12weeks). It confirms that these lncRNAs are positively associated with myogenic differentiation of satellite cells during skeletal muscle development.

This study extends the understanding of mechanisms governing transcriptional regulation of lncRNAs and provides a foundation for exploring their functions in skeletal muscle cell differentiation.

These states not only reduce quality of life of patients by increasing the appearance of psychiatric comorbidities, but also have an important impact on vulnerability to drug abuse, including alcohol. In fact, clinical, epidemiological but also preclinical studies have revealed that the presence of pain is closely related to alcohol use disorders (AUDs). All this evidence suggests that pain is a factor that increases the risk of suffering AUD, predicting heavy drinking behavior and relapse drinking in those patients with a previous history of AUD. The negative consequences of chronic pain and its impact on stress and AUD are likely mediated by alterations in the central nervous system, especially in the stress and reward systems. Therefore, pain and stress impact on dopaminergic mesolimbic pathway can lead to an increase in drug abuse liability. In this mini review we analyze the interaction between pain, stress, and alcohol addiction, and how dynamic changes in the kappa opioid system might play a crucial role in the development of compulsive alcohol drinking in chronic pain patients.

The aim of this study was to develop and assess the performance of supervised machine learning technique to classify magnetic resonance imaging (MRI) voxels as cancerous or noncancerous using noncontrast multiparametric MRI (mp-MRI), comprised of T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), and advanced diffusion tensor imaging (DTI) parameters.

In this work, 191 radiomic features were extracted from mp-MRI from prostate cancer patients. A comprehensive set of support vector machine (SVM) models for T2WI and mp-MRI (T2WI+DWI, T2WI+DTI, and T2WI+DWI+DTI) were developed based on novel Bayesian parameters optimization method and validated using leave-one-patient-out approach to eliminate any possible overfitting. The diagnostic performance of each model was evaluated using the area under the receiver operating characteristic curve (AUROC). The average sensitivity, specificity, and accuracy of the models were evaluated using the test data set and the corresponding binary maps generated. Finalramework of a supervised classification technique and Bayesian optimization method are able to differentiate cancer from noncancer voxels with high accuracy and without administration of contrast agent. Stem Cells agonist The addition of cancer probability maps provides additional functionality for image interpretation, lesion heterogeneity evaluation, and treatment management.Magnesium (Mg) based implants such as plates and screws are often preferred to treat bone defects because of the positive effects of magnesium in bone growth and healing. Their low corrosion resistance, however, leads to fast degradation and consequently failure before healing was completed. Previously, we developed Mg doped titanium nitrate (TiN) thin film coatings to address these limitations and demonstrated that less then 10 at% Mg doping led to enhanced mineralization in vitro. In the present study, in vivo performance of (Ti,Mg)N coated Ti6Al4V based plates and screws were studied in the rabbit model. Bone fractures were formed on femurs of 16 rabbits and then fixed with either (Ti,Mg)N coated (n = 8) or standard TiN coated (n = 8) plates and screws. X-ray imaging and μCT analyses showed enhanced bone regeneration on fracture sites fixed with (Ti,Mg)N coated plates in comparison with the Mg free ones. Bone mineral density, bone volume, and callus volume were also found to be 11.4, 23.4, and 42.8% higher, respectively, in accordance with μCT results. Furthermore, while TiN coatings promoted only primary bone regeneration, (Ti,Mg)N led to secondary bone regeneration in 6 weeks. These results indicated that Mg presence in the coatings accelerated bone regeneration in the fracture site. (Ti,Mg)N coating can be used as a practical method to increase the efficiency of existing bone fixation devices of varying geometry.

Several hematological indices including subtypes of leukocytes populations have been associated with cardiovascular outcome. Takotsubo syndrome (TTS) is a form of acute heart failure syndrome featured by several in-hospital complications (IHCs).

Hematological indices at admission may predict IHCs in TTS patients.

One hundred and sixty consecutive patients with TTS were enrolled in a multicenter prospective registry. Clinical data, admission hemogram, and IHCs were recorded.

Incidence of IHCs was 37%, including pulmonary edema 9%, cardiogenic shock 9%, need of invasive ventilation 10%, death 8%, stroke 2.5%, and left ventricular thrombi 6%. Patients with IHCs were older, more frequently male, with physical stressor-induced TTS, lower left ventricular ejection fraction at admission. Neutrophil/lymphocyte ratio (NLr) (12 ± 12 vs 7 ± 8, P = .002) and white blood cells/mean platelet volume ratio (1.2 ± 0.5 vs 1.0 ± 0.5, P = .03) at admission were significantly higher in patients with IHCs. NLr values were predictor of IHCs (Odds ratios [OR] 1.
