The red blood cell fatty acid composition objectively reflects the long-term dietary intake of several fatty acids. In patients undergoing carotid endarterectomy, we explored whether red blood cell status of selected fatty acids related to symptomatic carotid artery disease.

We included patients with symptomatic (n=22) and asymptomatic (n=23) carotid artery disease. We determined all-C181 trans, linoleic acid (LA, C182n6), alpha-linolenic acid (C183n3), and the omega-3 index (sum of eicosapentaenoic [C205n3] and docosahexaenoic [C226n3] acids) in both red blood cells and carotid plaque phospholipids by gas-chromatography.

In a multivariate logistic regression analysis, we only observed a significant association for LA, whose red blood cell status was inversely related to symptomatic carotid artery disease (odds ratio, 0.116 [95% CI, 0.022-0.607],
=0.011, for each 1-SD increase). selleck A similar result was observed for LA in carotid plaque phospholipids.

Cell membrane enrichment in LA, which reflects its intake, was inversely related to symptomatic carotid disease. This increases evidence supporting a favorable role of dietary LA in vascular health.

Epidemiology of cerebral venous thrombosis (CVT) has been reported to be changing. Because long-term nationwide data are needed to confirm this, we studied CVT occurrence between 2005 and 2014 in Finland.

All acute CVT admissions were retrieved from a mandatory registry covering mainland Finland. Patients aged ≥18 years were included. One admission per patient was allowed.

We identified 563 patients with CVT (56.5% women). Overall incidence was 1.32/100 000 (95% CI, 1.21-1.43) per year with a 5.0% annual increase. In people <55 years of age, incidence was 0.92/100 000 (0.76-1.10) for men and 1.65/100 000 (1.43-1.89) for women, whereas for those 55 years or older incidence was 1.61 (1.34-1.91) for men and 1.17 (0.96-1.41) for women. In-hospital mortality was 2.1% with no sex difference. One-year mortality was 7.9%. Long-term mortality was higher in men (adjusted hazard ratio, 1.61 [1.09-2.38]) and in older patients (1.95 [1.69-2.24]; per 10-year increment).

Overall incidence of CVT in Finland was similar to that reported in the Netherlands and in Australia. There was a 5.0% yearly increase in the rate of admissions while in-hospital mortality was low. Sex-specific incidence rates differed markedly between younger and older people. Long-term mortality increased with age and was higher in men.

However, experimental detection of RBP binding sites is still time-intensive and expensive. Algorithms based on machine learning can speed up detection of RBP binding sites. In this article, we propose a new deep learning method, DeepA-RBPBS, which can use RNA sequences and structural features to predict RBP binding site. DeepA-RBPBS uses CNN and BiGRU to extract sequences and structural features without long-term dependence issues. It also utilizes an attention mechanism to enhance the contribution of key features. The comparison shows that the performance of DeepA-RBPBS is better than that of the state-of-the-art predictors. In the testing on 31 datasets of CLIP-seq experiments over 19 proteins, MCC (AUC) is 8% (5%) higher than those of the latest method based on deep learning, iDeepS. We also apply DeepA-RBPBS to the target RNA data of RBPs related to diabetes (LIN28, RBFOX2, FTO, IGF2BP2, CELF1 and HuR). The results show that DeepA-RBPBS correctly predicted 41,693 samples, where iDeepS predicted 31,381 samples. Communicated by Ramaswamy H.

In the current study a total of 54 samples of infant food (juice and purée) were collected on the Serbian market. Liquid chromatography-tandem mass spectrometry with electrospray ionization method detected 18 out of 69 analyzed pesticide active substances in 55.6% of the samples, most frequently carbendazim and acetamiprid. Domestic products as opposed to the imported ones showed a substantially higher proportion of positive (85% vs 38%) and noncompliant (10% vs 0%) samples, a number of pesticides detected (15 vs 8), the proportion of the samples with multiple residues (85% vs 15%), the maximum number of residues in an individual sample (7 vs 2). Risk assessment was performed for the present pesticide active substances, which was estimated to remain below the level of concern for both acute and chronic adverse health effects.Our work is composed of a python program for programmatic data mining of PubChem to collect data to implement a machine learning-based AutoQSAR algorithm to generate drug leads for the flaviviruses-Dengue and West Nile. The drug leads generated by the program are fed as programmatic inputs to AutoDock Vina package for automated in silico modelling of interaction between the compounds generated as drug leads by the program and the chosen Dengue and West Nile drug target methyltransferase, whose inhibition leads to the control of viral replication. The machine learning-based AutoQSAR algorithm involves feature selection, QSAR modelling, validation and prediction. The drug leads generated, each time the program is run, are reflective of the constantly growing PubChem database which is an important dynamic feature of the program which facilitates fast and dynamic drug lead generation against the West Nile and Dengue viruses. The program prints out the top drug leads after screening PubChem library which is over a billion compounds.
