Effect of Swimming at Low Temperature on Uncoupling Protein Gene Expression in Skeletal Muscle of Wistar Rats

Int. j. morphol; 42 (3), 2024
SUMMARY: As the economy develops and living standards improve, overweight and obesity are increasingly prevalent. Currently, weight-loss medications are primarily administered orally or intravenously, which can result in poor targeting, low bioavailability, frequent administration, and high toxicity and ...

Cupiennius spiders (Trechaleidae) from southern Mexico: DNA barcoding, venomics, and biological effect

Background: Members of the genus Cupiennius Simon, 1891 are categorized as wandering spiders and are part of the family Trechaleidae. The genomics and proteomics of Cupiennius spiders from North America remain uncharacterized. The present study explores for the first time molecular data from the endemic...

A molecular and morphological study of Ascaris suum in a human-pig contact scenario in northeastern Brazil

The aim of the present study was to assess morphologic and genetic data on ascariasis in swine (Sus scrofa domesticus) and humans in low-resource rural and periurban communities in the state of Piauí, Brazil. Our cross-sectional survey included 100 fecal samples obtained from swine and 682 samples from ...

Taxonomia integrativa de espécies da série Shannoni de Psathyromyia (Psathyromyia) Barretto, 1962 (Diptera, Psychodidae, Phlebotominae) do estado de São Paulo

Os flebotomíneos são dípteros que habitam ambientes florestais e antrópicos e são encontrados comumente em cavernas. Com exceção da Antártica, habitam todos os demais continentes. Atualmente o grupo é composto por pouco mais de 1.000 espécies. As fêmeas são hematófagas e várias espécies ap...

DNA barcoding revels first records of three rare coleopteran genera in Northern lakes of Egypt

Braz. j. biol; 81 (4), 2021
Abstract One aquatic coleopteran species from family Dytiscidae and two aquatic coleopteran genera from family Hydrophilidae were recorded in the summer period and represent first records in the Egyptian lakes. Beetles were collected from two northern lakes, Lake Idku and Lake Burullus. They were identif...

Genetic variability of populations of the white-eared opossum, Didelphis albiventris Lund 1840 (Didelphimorphia; Didelphidae) in Brazil

Braz. j. biol; 79 (4), 2019
Abstract Didelphis albiventris are found throughout Northeast and Central Brazil to central-southern Uruguay and it was subject of few studies in a population level. Given this, the present study investigated the genetic variability of the species using the mitochondrial molecular marker cytochrome oxida...

Molecular phylogenetic analysis of Cysticercus ovis from Egypt based on MT-CO1 gene sequences

Abstract Cysticercus ovis or sheep measles is the larval stage of Taenia ovis, which is the intestinal tapeworm of dogs. It is found in the cardiac and skeletal muscles of sheep and can be the cause of partial or total condemnation of carcasses at abattoirs. The aim of the current work was to determine t...

Analysis of COI and ITS2 regions of DNA obtained from Paragonimus westermani eggs in ancient coprolites on Joseon dynasty mummies

Mem. Inst. Oswaldo Cruz; 114 (), 2019
The genetic information of ancient Paragonimus westermani, the oriental lung fluke infecting over 20 million people worldwide, has not been thoroughly investigated thus far. We analysed genetic markers (COI and ITS2) of P. westermani from coprolite specimens (n = 6) obtained from 15th to 18th century Kor...

Especies Crípticas Lutzomyia longipalpis (Diptera: Phlebotominae) y sus Implicaciones en la Transmisión de Leishmaniasis en Panamá

Rev. méd. Panamá; 39 (1), 2019
Lutzomyia longipalpis es el principal v ector de una importante enfermedad desatendida en América. La diversidad genética de este vector se estimó en la población colectada en dos áreas geográficas separadas por hasta 37 km. Analizamos la secuencia CB3­PDR / N1N­PDR de 22 individuos obte­ nie...
