Herein, we propose magnetic nanocomposites as a powerful new catalyst for organic pollutant reduction. Polypyrrole (PPy) was synthesized in situ within the semi-interpenetrating alginate (Alg)/gelatin (Ge) network in presence of α-FeO as encapsulating matrix and inorganic filler, respectively. The polymeric matrix can act as bifunctional agent such as a binder and stabilizer to improve nanocatalyst stability while preserving their catalytic/magnetic performances.

PqsE and RhlR, key regulators of the Pseudomonas aeruginosa quorum sensing (QS) system, form a hetero-tetrameric complex essential for controlling the expression of virulence factors such as pyocyanin. The interaction between the PqsE homodimer and the RhlR homodimer bound to C4-HSL, enables RhlR to bind low-affinity promoters, thereby influencing gene regulation. Recent studies suggest that RhlR transcriptional activity is modulated by temperature, exhibiting higher activity at environmental temperatures (25 °C) compared to mammalian body temperature (37 °C).

Int J Neonatal Screen

December 2024

Laboratory of Genomic, Epigenetics, Precision and Predictive Medicine, School of Medicine, Mohammed VI University of Sciences and Health, Casablanca 82403, Morocco.

Unlabelled: Newborn screening (NBS) represents an important public health measure for the early detection of specified disorders; such screening can prevent disability and death, not only from metabolic disorders but also from endocrine, hematologic, immune, and cardiac disorders. Screening for critical congenital conditions affecting newborns' health is a great challenge, especially in developing countries such as Morocco, where NBS program infrastructure is lacking. In addition, the consanguinity rate is high in Morocco.

Evans syndrome (ES) is a rare syndrome characterised by the association of autoimmune idiopathic hemolytic anemia (AIHA) with immune thrombocytopenia (ITP) and, less commonly, autoimmune neutropenia (AIN). ES may be primary or secondary to some aetiology, including, exceptionally, tuberculosis. We describe a case of association between pulmonary and medullary tuberculosis and Evans syndrome with an effective response to antitubercular treatment and corticosteroids.

Noncentrifugal sugar (NCS) is an unrefined, dark brown sugar containing minerals and plant secondary metabolites, unlike refined white sugar (WS). This study explored using NCS in confectionary jellies as an alternative sugar. We used different concentrations of NCS and WS to prepare low methoxyl pectin (LMP) confectionery gels characterized by their physical and rheological properties along with time-domain nuclear magnetic resonance (TD-NMR) relaxometry.

AneRBC dataset: a benchmark dataset for computer-aided anemia diagnosis using RBC images.

Database (Oxford)

December 2024

School of Computing and Mathematical Sciences, University of Leicester, University Road, Leicester LE1 7RH, UK.

Visual analysis of peripheral blood smear slides using medical image analysis is required to diagnose red blood cell (RBC) morphological deformities caused by anemia. The absence of a complete anaemic RBC dataset has hindered the training and testing of deep convolutional neural networks (CNNs) for computer-aided analysis of RBC morphology. We introduce a benchmark RBC image dataset named Anemic RBC (AneRBC) to overcome this problem.

This article studies the synthesis, as well as the structural, vibrational, and optical properties of Eu-doped ZnO quantum dots (QDs) and investigates the energy transfer mechanism from the ZnO host to Eu ions using Reisfeld's approximation. Eu-doped ZnO QDs at varying concentrations (0-7%) were successfully prepared using a wet chemical method. The successful doping of Eu ions into the ZnO host lattice, as well as the composition and valence states of the elements present in the sample, were confirmed through X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) analyses.

This study introduces a UiO-66-NH2/Tannic acid/Polyvinylidene fluoride (UTP) composite membrane for efficient oil-water separation. Pristine polyvinylidene fluoride (PVDF) membranes, due to their hydrophobic nature, tend to foul during oil-in-water emulsion separation. By incorporating the metal-organic framework (MOF) UiO-66-NH2 and stabilizing it with tannic acid (TA) and polyvinyl alcohol (PVA), the membrane's hydrophilicity and antifouling properties were significantly enhanced.

In Salmonella Typhimurium, efflux pump proteins, such as AcrD actively expel drugs and hazardous chemicals from bacterial cells, resulting in treatment failure and the emergence of antibiotic-resistant variants. Focusing on AcrD may lead to the development of novel antimicrobials against multidrug-resistant bacteria. However, challenges persist in achieving high selectivity, low toxicity, and effective bacterial penetration.

Advancement in medical report generation: current practices, challenges, and future directions.

Med Biol Eng Comput

December 2024

Department of Information and Communication Engineering, Yeungnam University, Gyeongsan, 38541, Republic of Korea.

The correct analysis of medical images requires the medical knowledge and expertise of radiologists to understand, clarify, and explain complex patterns and diagnose diseases. After analyzing, radiologists write detailed and well-structured reports that contribute to the precise and timely diagnosis of patients. However, manually writing reports is often expensive and time-consuming, and it is difficult for radiologists to analyze medical images, particularly images with multiple views and perceptions.

Article Synopsis
  • The text discusses the impact of pneumococcal conjugate vaccines (PCVs), specifically PCV10 and PCV13, on invasive pneumococcal disease (IPD) globally, highlighting how these vaccines have reduced the prevalence of disease caused by vaccine-type serotypes after extensive use.
  • It describes the methodology of data collection from various surveillance sites, which aimed to evaluate IPD cases that occurred five years after the vaccines were implemented, focusing on different age groups for analysis.
  • Findings indicate significant differences in serotype distribution between PCV10 and PCV13 sites; notably, certain serotypes, such as 19A and serotype 3, were prevalent in specific age groups, signaling ongoing challenges in controlling

Background: Pneumococcal conjugate vaccines (PCVs) that are ten-valent (PCV10) and 13-valent (PCV13) became available in 2010. We evaluated their global impact on invasive pneumococcal disease (IPD) incidence in all ages.

Methods: Serotype-specific IPD cases and population denominators were obtained directly from surveillance sites using PCV10 or PCV13 in their national immunisation programmes and with a primary series uptake of at least 50%.

Environ Monit Assess

December 2024

Faculty of Geography and Geology, University of Sciences, Hue University, Hue City, Vietnam.

Land surface temperature (LST) serves as a crucial indicator for evaluating the effects of different environmental factors on the ecosystem, including alterations in land use, climate variations, and emissions of greenhouse gases. This comprehensive study used remote sensing data to analyze changes and effects of land use/land cover (LULC) on LST in Tay Ninh province, Vietnam, from 1988-2023. Landsat satellite images in 1988, 2004, and 2023 were preprocessed and supervised classification on ArcGIS 10.

Background: The development of a robust and accurate point-of-care platform for the detection of tuberculosis (TB) biomarkers is important for disease control. In the current study, the detection principle relies on the shredding of PES-modified non-specific ssDNA (Poly T) in the presence of target DNA IS6110, a reliable biomarker for TB diagnosis by the CRISPR-Cas12a mechanism. Cas protein has great potential in the detection of nucleic acids.
