Synthesis and characterization of dextran palmitate for extrusion 3D printing.

The fabrication of objects with complex shape and geometry has been greatly facilitated with the advancements in additive manufacturing. While synthetic polymers like ABS and PLA have found widespread use in extrusion 3D printing, other biobased thermoplastics that are both biodegradable and biocompatible could offer strategic advantages over traditional synthetic materials. In this work dextran of low (20 kDa) and medium (40 kDa) molecular weight (MW) was modified with palmitic acid to obtain meltable polymers for extrusion 3D printing/fused deposition modeling additive manufacturing.

Classification of non-TCGA cancer samples to TCGA molecular subtypes using compact feature sets.

Molecular subtypes, such as defined by The Cancer Genome Atlas (TCGA), delineate a cancer's underlying biology, bringing hope to inform a patient's prognosis and treatment plan. However, most approaches used in the discovery of subtypes are not suitable for assigning subtype labels to new cancer specimens from other studies or clinical trials. Here, we address this barrier by applying five different machine learning approaches to multi-omic data from 8,791 TCGA tumor samples comprising 106 subtypes from 26 different cancer cohorts to build models based upon small numbers of features that can classify new samples into previously defined TCGA molecular subtypes-a step toward molecular subtype application in the clinic.

Production of primary metabolites by Pseudomonas reptilivora B-6bs at the flask level using a full factorial experimental design.

The metabolites gluconic acid, 5-ketogluconic acid, proline, and glutamic acid, produced by Pseudomonas reptilivora B-6bs, are industrially important, particularly in food and pharmaceutical sectors. However, producing these metabolites involves biotin supplementation to enhance yields, which is an expensive additive, and reducing its use can significantly lower production costs. Thus, This study aimed to enhance the production of gluconic acid, 5-ketogluconic acid, proline, and glutamic acid without biotin supplementation.

Early Onset Active Inflammatory Bowel Disease Is Associated With Psychiatric Comorbidities: A Multi-Network Propensity-Matched Cohort Study.

Background: Psychiatric disease burden in patients with Inflammatory bowel disease (IBD) has risen substantially over the past few decades. However, there is limited data on the relationship between IBD disease activity and the incidence of psychiatric comorbidities. We sought to conduct a population-based study to investigate the impact of early onset disease activity in newly diagnosed IBD patients on psychiatric disease diagnoses and medication usage.

Education Research: The Neurohumanities in Training: Integrating a Humanities Curriculum Within Neurology Residency Programs.

Background And Objectives: Perhaps stemming from the central role of detailed examinations and a focus on the subjective sphere that grounds their clinical practice, neurologists have frequently opined on experiences traditionally a province of humanities. The increasingly technological focus on medical education and care can be seen to devalue the subjective aspects of medicine. As a counter to this, we report on the existence of neurohumanities curricula within neurology residency training.

A Lactobacillus consortium provides insights into the sleep-exercise-microbiome nexus in proof of concept studies of elite athletes and in the general population.

Background: The complex relationship among sleep, exercise, and the gut microbiome presents a unique opportunity to improve health and wellness. Here, we conducted the first large-scale investigation into the influence of a novel elite athlete-derived probiotic, consisting of a multi-strain Lactobacillus consortium, on sleep quality, exercise recovery, and gut microbiome composition in both elite athletes (n = 11) and the general population (n = 257).

Results: Our two-phase study design, which included an open-label study followed by a controlled longitudinal study in a professional soccer team, allowed us to identify key interactions between probiotics, the gut microbiome, and the host.

Orthogonal validation of PROTAC mediated degradation of the integral membrane proteins EGFR and c-MET.

Dysregulation of integral membrane proteins (IMPs) has been linked to a myriad of diseases, making these proteins an attractive target in drug research. Whilst PROTAC technology has had a significant impact in scientific research, its application to IMPs is still limited. Limitations of the traditional approach of immunoblotting in PROTAC research include the low throughput compared to other methods, as well as a lack of spatial information for the target.

Multimaterial cryogenic printing of three-dimensional soft hydrogel machines.

Hydrogel-based soft machines are promising in diverse applications, such as biomedical electronics and soft robotics. However, current fabrication techniques generally struggle to construct multimaterial three-dimensional hydrogel architectures for soft machines and robots, owing to the inherent hydrogel softness from the low-density polymer network nature. Herein, we present a multimaterial cryogenic printing (MCP) technique that can fabricate sophisticated soft hydrogel machines with accurate yet complex architectures and robust multimaterial interfaces.

Reactivation of hidden-latent infection after doxycycline and streptomycin treatment in mice.

Brucellosis has therapeutic challenges due to 3%-15% relapses/therapeutic failures (R/TF) after antibiotic treatment. Therefore, determining the antibiotic concentration in tissues, the physiopathological parameters, and the R/TF after treatment is relevant. After exploring different antibiotic quantities, we found that a combined dose of 100 µg/g of doxycycline (for 45 days) and 7.

Polymorphisms in the gene and neuroblastoma risk in Chinese children from Jiangsu province.

Neuroblastoma is the most prevalent extracranial solid tumor among children and exhibits remarkable heterogeneity. The methylation of cytosine to form 5-methylcytosine (m5C) is the primary type of modification found in DNA and RNA. The NOL1/NOP2/sun (NSUN) family, specifically NSUN1, is responsible for the methylation process and has been shown to play a key role in cell differentiation and cancer development.

Influence of the addition of gum arabic and xanthan gum in the preparation of sodium alginate microcapsules coated with chitosan hydrochloride on the survival of Lacticaseibacillus rhamnosus GG.

The microencapsulation of Lactocaseibacillus rhamnosus GG in a matrix of sodium alginate, xanthan gum, gum arabic and chitosan hydrochloride is a promising strategy for protecting this probiotic during passage through the gastrointestinal tract. This study evaluated the influence on the viability of Lactocaseibacillus rhamnosus GG encapsulated with these polymers by external ionic gelation with vibratory extrusion and the microcapsules that showed the best results of capsulation efficiency, viability, size and morphology were analyzed by Fourier transform infrared spectroscopy (FTIR), thermal analysis (TGA) and exposure to environmental stress conditions and gastrointestinal simulation. The result revealed encapsulation efficiency values above 95 % for all formulations and survival rate higher than 6 log CFU/mL for most analyzed groups.

Impact of DNA Ligase 1 Genotypes on Childhood Acute Lymphocytic Leukemia.

Activation of Caged Functional RNAs by An Oxidative Transformation.

RNA exhibits remarkable capacity as a functional polymer, with broader catalytic and ligand-binding capability than previously thought. Despite this, the low side chain diversity present in nucleic acids (two purines and two pyrimidines) relative to proteins (20+ side chains of varied charge, polarity, and chemical functionality) limits the capacity of functional RNAs to act as environmentally responsive polymers, as is possible for peptide-based receptors and catalysts. Here we show that incorporation of the modified nucleobase 2-thiouridine (2sU) into functional (aptamer and ribozyme) RNAs produces functionally inactivated polymers that can be activated by oxidative treatment.
