This study utilized cultivable methods and 16 S amplicon sequencing to compare taxonomic profiles and functional potential of gut bacteria in the scarab beetle, Anomola dimidiata, under cellulose-enriched conditions. Eight culturable cellulolytic gut bacteria were isolated from the midgut and hindgut of the scarab larvae, respectively. 16 S amplicon sequencing evinced that the most represented taxonomic profiles at phylum level in the fermentation chamber and midgut were Bacillota (71.

This study investigates gut microbiota diversity and enzymatic activities, aiming to utilize identified isolates for practical applications in sustainable crop residue management and soil health enhancement. This study sampled honey bees, analyzed gut bacterial diversity via 16S rRNA gene, and screened isolates for cellulolytic, hemicellulolytic, and pectinolytic activities, with subsequent assessment of enzymatic potential. The study reveals that cellulolytic and hemicellulolytic bacterial isolates, mainly from γ-Proteobacteria, Actinobacteria, and Firmicutes, have significant potential for crop residue management.

Purpose: To compare the discrimination performance of 6-year-old children for optotypes from six paediatric visual acuity tests and to fit Luce's Biased Choice Model to the data to estimate the relative similarities and bias for each optotype.

Methods: Full data sets were collected from 20 typically developing 6-year-olds who had passed a vision screening. They were presented with single optotypes labelled 6/12 at a distance of 9 m and were asked to identify the optotype using a matching task containing all optotypes from the relevant test.

Purpose: Center-surround contrast suppression-typically induced when a center pattern is surrounded by another pattern with similar spatial features-is considered a perceptual analogue of center-surround neurophysiology in the visual system. Surround suppression strength is altered in a range of brain conditions affecting young people (e.g.

Article Synopsis
  • Very early-onset inflammatory bowel disease (VEOIBD) occurs in children under six and can be treated with hematopoietic stem cell transplantation (HSCT).
  • A study between December 2012 and December 2020 included 25 children with various monogenic disorders who underwent HSCT, revealing an overall survival rate of 64% and highlighting the vital role of complete chimerism in preventing disease recurrence.
  • Findings showed that mixed chimerism led to a significantly higher mortality risk, emphasizing the importance of early diagnosis and comprehensive care for better outcomes in VEOIBD.

This work studies the dynamics of a three dimensional Hopfield neural network focusing on the impact of bias terms. In the presence of bias terms, the models displays an odd symmetry and experiences typical behaviors including period doubling, spontaneous symmetry breaking, merging crisis, bursting oscillation, coexisting attractors and coexisting period-doubling reversals as well. Multistability control is investigated by employing the linear augmentation feedback strategy.

We aimed to analyze infections in children undergoing hematopoietic stem cell transplantation (HSCT) until engraftment. The spectrum and risk factors associated will help plan interventions to reduce mortality. We performed a retrospective analysis on the infections, associated risk factors, and mortality until engraftment in children up to 18 years of age undergoing HSCT from January 2017 to August 2020.

Rabies is a major disease burden worldwide, especially in Asia. Approximately, 59,000 human deaths per year occurs in over 150 countries due to rabies, with Africa and Asia contributing 95% of cases. It is a fatal infection of central nervous system (CNS) caused by rabies RNA virus via transmission through bite of an infected animal, aerosols, open wound, or organ transplantation.

Certain chemicals/materials that are contaminants of emerging concern (CECs) have been widely detected in water bodies and terrestrial systems worldwide while other CECs occur at undetectable concentrations. The primary sources of CECs in farmlands are agricultural inputs, such as wastewater, biosolids, sewage sludge, and agricultural mulching films. The percent increase in cropland area during 1950-2016 was 30 and the rise in land use for food crops during 1960-2018 was 100-500%, implying that there could be a significant CEC burden in farmlands in the future.

Introduction: Malnutrition is a widely prevalent yet unrecognized problem of patients with end-stage liver disease (ESLD) awaiting liver transplant (LT). The aim of this study was to ascertain pre-LT nutritional status of adult Asian Indian patients with ESLD including functional deficit (frailty) and determine predictor/s of poor post-LT outcome (futility).

Methods: A prospective, longitudinal, single-center study which enrolled adults listed for LT between October 2014 and April 2018.

In this paper, bidirectional-coupled neurons through an asymmetric electrical synapse are investigated. These coupled neurons involve 2D Hindmarsh-Rose (HR) and 2D FitzHugh-Nagumo (FN) neurons. The equilibria of the coupled neurons model are investigated, and their stabilities have revealed that, for some values of the electrical synaptic weight, the model under consideration can display either self-excited or hidden firing patterns.

Soil pollution by the contaminants of emerging concern (CECs) or emerging contaminants deserves attention worldwide because of their toxic health effects and the need for developing regulatory guidelines. Though the global soil burden by certain CECs is in several metric tons, the source-tracking of these contaminants in soil environments is difficult due to heterogeneity of the medium and complexities associated with the interactive mechanisms. Most CECs have higher affinities towards solid matrices for adsorption.
