Not all viruses in nature are human enemies: a perspective on aquatic virus ecology in Brazil

Acta Limnologica Brasiliensia, 2020
: Viruses cause various diseases in humans through vector-borne (e.g., Zika and dengue fever), airborne (e.g., measles) and water-borne (e.g., hepatitis) transmission, as well as direct physical contact (e.g., AIDS and herpes).

Aquatic viral ecology

, 2021
Marine and freshwater viruses, from polar regions to tropical systems, are a huge reservoir of genetic diversity and are key players in regulating host population dynamics and subsequently carbon cycling in the microbial food web. This session will explore the ecology of aquatic viruses, ranging from their diversity to their role as agents of microbial

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Genomic diversity and global distribution of four new prasinoviruses from the tropical north Pacific

Microbiology Spectrum
Viruses that infect phytoplankton are an integral part of marine ecosystems, but the vast majority of viral diversity remains uncultivated. Here, we introduce four near-complete genomic assemblies of viruses that infect the widespread marine ...

Shotgun Metagenomic Profiling of the Gut Virome in Prodromal and Confirmed Parkinson's Disease

Annals of Neurology, EarlyView.
We conducted a nested case‐control study within the Nurses’ Health Study and the Health Professionals Follow‐up Study to examine the role of the gut virome (GV) in Parkinson's disease (PD). We applied a novel metagenomic virome profiling approach, Bioinformatic Application for Quantification and Labeling of Viral taxonomy (BAQLaVa), to prospectively ...

Reannotation of the Ribonucleotide Reductase in a Cyanophage Reveals Life History Strategies Within the Virioplankton

Frontiers in Microbiology, 2019
Ribonucleotide reductases (RNRs) are ancient enzymes that catalyze the reduction of ribonucleotides to deoxyribonucleotides. They are required for virtually all cellular life and are prominent within viral genomes.

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

Applications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Inferring phage–bacteria infection networks from time-series data [PDF]

Royal Society Open Science, 2016
In communities with bacterial viruses (phage) and bacteria, the phage–bacteria infection network establishes which virus types infect which host types. The structure of the infection network is a key element in understanding community dynamics. Yet, this

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Dietary Baicalin Supplementation Can Enhance the Growth Performance of Weaned Piglets and Maintain the Intestinal Barrier Integrity

Animal Research and One Health, EarlyView.
This research innovatively illustrates baicalin’s multifaceted mechanisms in enhancing piglets’ intestinal health: modulating bile acid metabolism via probiotics, reinforcing tight junction proteins (ZO‐1/claudin), suppressing TLR4/NF‐κB‐mediated inflammation, whereas promoting growth and reducing diarrhea.
