The use of PCR-RFLP to genetically distinguish the morphologically close species: Ceriodaphnia dubia Richard, 1894 and Ceriodaphnia silvestrii Daday, 1902 (Crustacea Cladocera)

open access: yesBrazilian Journal of Biology
The cladocerans are important components of planktonic and benthic freshwater and good indicators of the trophic state of water bodies. The morphological taxonomy of many species of Cladocera is considered complex with minor differences separating some ...

Complete mitochondrial and rDNA complex sequences of important vector species of Biomphalaria, obligatory hosts of the human-infecting blood fluke, Schistosoma mansoni

open access: yesScientific Reports, 2018
Using high throughput Illumina sequencing technology, we determined complete sequences for the mitochondrial genome (mitogenome) and nuclear ribosomal DNA (rDNA) complex for three African freshwater snail taxa within the genus Biomphalaria, B. pfeifferi,

Outbreak investigation of food poisoning attributed to Omphalotus japonicus using polymerase chain reaction‐based sequencing

open access: yesHong Kong Journal of Emergency Medicine, Volume 31, Issue 6, Page 472-477, December 2024.
Abstract Objective This study aims to report and analyse an outbreak of Omphalotus japonicus poisoning following mushroom ingestion in Taiwan, and to employ PCR methods for accurate identification of the toxic mushrooms involved. Methods A descriptive observational study was conducted involving a family of four who ingested the mushrooms in the ...

A Multiplex-PCR approach to identification of the Brazilian intermediate hosts of Schistosoma mansoni

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
Due to difficulties concerning morphological identification of planorbid snails of the genus Biomphalaria, and given a high variation of characters and in the organs with muscular tissue, we designed specific polymerase chain reaction (PCR) primers for ...

Analyzing the role of ferroptosis in ribosome‐related bone marrow failure disorders: From pathophysiology to potential pharmacological exploitation

open access: yesIUBMB Life, Volume 76, Issue 12, Page 1011-1034, December 2024.
Abstract Within the last decade, the scientific community has witnessed the importance of ferroptosis as a novel cascade of molecular events leading to cellular decisions of death distinct from apoptosis and other known forms of cell death. Notably, such non‐ apoptotic and iron‐dependent regulated cell death has been found to be intricately linked to ...

Pterostilbene Targets Hallmarks of Aging in the Gene Expression Landscape in Blood of Healthy Rats

open access: yesMolecular Nutrition &Food Research, Volume 68, Issue 24, December 2024.
The study characterizes transcriptomic patterns in blood of healthy rats consuming diets supplemented with polyphenols. Supplementation with pterostilbene (PTS), a dietary bioactive compound from a group of phytoestrogens, resulted in gene expression changes that are functionally linked to hallmarks of aging.

Nucleolar actions in plant development and stress responses

open access: yesPlant, Cell &Environment, Volume 47, Issue 12, Page 5189-5204, December 2024.
Abstract The nucleolus is conventionally acknowledged for its role in ribosomal RNA (rRNA) synthesis and ribosome biogenesis. Recent research has revealed its multifaceted involvement in plant biology, encompassing regulation of the cell cycle, development, and responses to environmental stresses. This comprehensive review explores the diverse roles of

CoFold: thermodynamic RNA structure prediction with a kinetic twist [PDF]

open access: yesarXiv, 2012
Existing state-of-the-art methods that take a single RNA sequence and predict the corresponding RNA secondary-structure are thermodynamic methods. These predict the most stable RNA structure, but do not consider the process of structure formation. We have by now ample experimental and theoretical evidence, however, that sequences in vivo fold while ...

Species Diversity, Host Association, and Evolutionary History of Cronartium: An Important Global Fungal Pathogen to Trees

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
We determined that Cronartium probably occurred around 91.78 Ma during the Upper Cretaceous. Cronartium species may originated in Asia and North America and subsequently had several intercontinental dispersals via the North Atlantic Land Bridge, the De Geer Route, and the Bering Land Bridge. Additionally, we found that the diversification of Cronartium

Homortomyces gen. nov., a new dothidealean pycnidial fungus from the Cradle of Humankind

open access: yesIMA Fungus, 2012
Homortomyces is introduced as a new coelomycetous genus associated with leaf spots on Combretum erythrophyllum trees growing near and around the Sterkfontein caves, Maropeng, South Africa. Based on its transversely septate, brown conidia, the presence of
