Molecular methods are powerful tools in characterizing and determining relationships between plants. The aim of this study was to study genetic divergence between 103 accessions of Mexican Opuntia. To accomplish this, polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis of three chloroplast intergenic spacers (atpB-rbcL, trnL-trnF, and psbA-trnH), one chloroplast gene (ycf1), two nuclear genes (ppc and PhyC), and one mitochondrial gene (cox3) was conducted.
The myosin heavy chain (MyHC) composition, glycolytic potential, mitochondrial content, and gene expression related to energy metabolism were analyzed in eight muscles from Tibetan pigs, to study how meat quality develops in different muscle tissues.
Mutations in mitochondrial DNA have been found to be associated with hypertension. Of these, mitochondrial transfer RNA (mt-tRNA) is a hot spot for these pathogenic mutations. It is generally believed that these mutations may result in the failure of mt-tRNA metabolism, thereby worsening mitochondrial dysfunction and resulting in hypertension. mt-tRNA is known for its high frequency of polymorphisms and mutations, and the number of reports regarding mt-tRNA mutations and hypertension is increasing significantly.
We aimed to evaluate the effect of melatonin on myocardial cell oncosis in the myocardial ischemia/reperfusion injury rat, and the role of the mitochondrial permeability transition pore (MPTP) therein. Sprague Dawley rats (N = 60) were randomly divided into five groups of 12 rats each: control, ischemia/reperfusion (I/R), melatonin treatment (MT), melatonin treatment + atractyloside (MT+ATR), and atractyloside (ATR). We prepared the myocardial ischemia/reperfusion model by reperfusion after the left anterior descending coronary artery was ligated for 30 min.
