Anthelmintic resistance occurs worldwide in strongyles of ruminants but data from low-income countries are sparse and rarely apply most up to date methods, while effects of management practices in these countries are poorly documented. In Mozambique, benzimidazole resistance has been previously reported; the present study followed this up in detail, applying in vivo faecal egg count (FEC) reduction test (FECRT), in vitro egg hatch test (EHT) and molecular deep amplicon sequencing approaches targeting the internal transcribed spacer 2 (ITS-2, nemabiome) and the isotype 1 β-tubulin gene to determine the resistance status on farms and the strongyle species involved. Adult Landim goats (433) from six semi-intensive and ten extensive farms (22-30 animals/farm) from Maputo Province were visited April 2021 to February 2022.

The signaling pathways behind severe astrocytic lysis with Aquaporin4 auto-antibody (AQP4-IgG) seropositivity, and reactive astrocytosis with myelin oligodendrocyte glycoprotein auto-antibody (MOG-IgG) seropositivity, remain largely unexplored in Neuromyelitis optica spectrum disorder (NMOSD), while almost no molecular details being known about double-seronegative (DN) patients. Recent discovery of glial fibrillary acidic protein (GFAP) in DN NMOSD patients' cerebrospinal fluid, akin to AQP4-IgG + ve cases, suggests astrocytopathy. Here, we aim to study small non coding RNA (sncRNA) signature alterations in astrocytes exposed to AQP4-IgG + ve and MOG-IgG + ve patient sera, and their potential resemblance with DN-NMOSD.

Dysfunction of the centrosome, the major microtubule-organizing center of the cell, is implicated in microcephaly. Haploinsufficiency of mixed-lineage leukemia (MLL/KMT2A) protein causes Wiedemann-Steiner syndrome (WSS), a neurodevelopmental disorder associated with microcephaly. However, whether MLL has a function at the centrosome is not clear.

Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

Introduction: Contracting HIV, syphilis, hepatitis B virus (HBV), and malaria during pregnancy significantly affects the health of the woman, the pregnancy, and the unborn child. The World Health Organization (WHO) recommends testing pregnant women for these infections to achieve triple elimination of mother-to-child transmissions. However, this goal has not been fully realized in low- to medium-income countries, primarily due to segmented testing practices.

Protein engineering through directed evolution and (semi)rational design has become a powerful approach for optimizing and enhancing proteins with desired properties. The integration of artificial intelligence methods has further accelerated protein engineering process by enabling the development of predictive models based on data-driven strategies. However, the lack of interpretability and transparency in these models limits their trustworthiness and applicability in real-world scenarios.

Role of chemokines in aging and age-related diseases.

Mech Ageing Dev

February 2025

Molecular Biology Laboratory, School of Life Sciences, Jawaharlal Nehru University, New Delhi 110067, India. Electronic address:

Chemokines (chemotactic cytokines) play essential roles in developmental process, immune cell trafficking, inflammation, immunity, angiogenesis, cellular homeostasis, aging, neurodegeneration, and tumorigenesis. Chemokines also modulate response to immunotherapy, and consequently influence the therapeutic outcome. The mechanisms underlying these processes are accomplished by interaction of chemokines with their cognate cell surface G protein-coupled receptors (GPCRs) and subsequent cellular signaling pathways.

  • The study investigates the role of a master regulator gene in the development of excitatory neurons, specifically focusing on its function in cerebellar granule neuron progenitors (GNPs).
  • Researchers found that dysfunction of this gene in GNPs reduced their proliferation and led to various cerebellar abnormalities, including hypoplasia and imbalances in neuron ratios.
  • The findings suggest that deletion of this gene during early development can cause autism-like behaviors in mice and highlight uncharacterized gene variants associated with autism spectrum disorder in humans.

Introduction Maternal mortality remains a critical global health issue, with ongoing efforts to reduce its incidence as part of international health priorities. Kenya, a sub-Saharan country that has a disproportionate number of maternal mortality is likely to miss this target unless evidence-based interventions are deployed. The paucity of reliable maternal health data calls for the development of alternative predictive models to complement the impaired civil registration system and the aperiodic national surveys.

Microorganisms

November 2024

Laboratory of Biochemistry, Biomedical Department, Health Sciences Faculty, Centre for Biotechnology and Bioengineering (CeBiB), Universidad de Antofagasta, Antofagasta 1240000, Chile.

The Amuyo Ponds (APs) are a group of three brackish hydrothermal lagoons located at 3700 m above sea level in a pre-Andean setting in the Atacama Desert. Each pond shows a conspicuous green (GP), red (RP), or yellow (YP) coloration, and discharges water rich in arsenic and boron into the Caritaya River (Camarones Basin, northern Chile). Microorganisms are subjected to harsh environmental conditions in these ponds, and the microbial composition and diversity in the Amuyo Ponds' sediments are unknown.
