The Use of Cytochrome b Gene as a Specific Marker of the Rat Meat (Rattus norvegicus) on Meat and Meat Products

open access: yesMedia Peternakan, 2012
Falsification of the origin of livestock meat and its processed with rat meat is a problem that must be overcome to ensure food safety. One way that is often used to detect forgeries by using cytochrome b gene as a marker.

Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]

open access: yes, 2015
Multi-heme cytochromes are employed by a range of microorganisms to transport electrons over distances of up to tens of nanometers. Perhaps the most spectacular utilization of these proteins is in the reduction of extracellular solid substrates ...

Phylogenetic Relationships of the Bumblebee Subgenus Pyrobombus (Hymenoptera: Apidae) Inferred from Mitochondrial Cytochrome B and Cytochrome Oxidase I Sequences [PDF]

open access: yes, 2017
Traditionally, the genus Bombus (Apidae: Apinae: Bombini) is divided into several subgenera. This study derives an approximation of the relationships between 10 species of the subgenus Pyrobombus (from both Europe and North America), B. lapidarius L. and

Mitochondria‐Targeted Nanomotor: H2S‐Driven Cascade Therapy for Hepatocellular Carcinoma

open access: yesAdvanced Materials, EarlyView.
A mitochondrial‐targeted nanomotor integrates photodynamic therapy, mild photothermal therapy, and enzyme dynamic therapy into a self‐amplifying cascade through H2S‐driven metabolic reprogramming. Abstract Despite advances in combination therapies for cancer treatment, most strategies rely on modular‐additive designs that lack dynamic molecular cues to

Mitochondria‐Specific Protein Delivery by Protease‐Triggered Release in Plants with Single‐Walled Carbon Nanotubes

open access: yesAdvanced Materials Technologies, EarlyView.
Polymer‐coated carbon nanotubes were engineered as protease‐responsive nanocarriers for protein delivery in intact plants. GFP cargo can be released by cytosolic phytaspase cleavage and subsequently targeted to mitochondria via an N‐terminal sequence, enabling controlled intracellular protein delivery without tissue damage and demonstrating stable ...

The association between faecal host DNA or faecal calprotectin and feed efficiency in pigs fed yeast-enriched protein concentrate

open access: yesAnimal, 2019
Gut cell losses contribute to overall feed efficiency due to the energy requirement for cell replenishment. Intestinal epithelial cells are sloughed into the intestinal lumen as digesta passes through the gastrointestinal tract, where cells are degraded ...
