Abstract Objective: The objective of this study was to determine the level of methotrexate (MTX) toxicity in the intestines of mice and to evaluate the protective effect of probiotics composed of Streptococcus, Bifidobacterium, and Lactobacillus species on intestinal cells during MTX treatment. Methods: Mice were divided into three groups: control, MTX group (received MTX injections), and MTX + probiotics group (received MTX injections along with a diet containing probiotics). Morphological and histological changes, the level of mitochondrial DNA (mtDNA) damage, the level of lipid peroxidation products, and gene expression in the mice’s small intestine were assessed. Results: We… More > Graphic Abstract

Abstract Objective: In general, a mitochondrial disorder is diagnosed on the basis of symptom combinations and confirmed by genetic findings. However, patients carrying the m.3243A>G mutation in the mitochondrial tRNA leucine 1 (MT‐TL1) do not always meet all the proposed criteria for the most frequently encountered mitochondrial syndrome “MELAS,” an acronym for Mitochondrial Encephalomyopathy, Lactic Acidosis, and at least one Stroke‐like episode. We here present various phenotypic characteristics of the mitochondrial mutation m.3243A>G with particular focus on cardiac manifestations.
Methods and Results: We followed nine patients (1 month to 68 years old; median 42 years; four female and five male) from… More >

Abstract Six mitochondrial (mtDNA) markers, cox2, ccmFn, ccb256, cox3, Nad4L-orf25, and atp4, were combined to assess genetic relationships by using Maximum Likelihood (ML) and Maximum parsimony (MP). This was done among nine Chinese Curcuma herbal species, included two rare species which are difficult to distinguish from their morphological characters. The relationships are very close among the nine species, and the overall distance was 0.018. In this study, the backbone of such nine species was achieved firstly to date, and being divided into two groups with moderate to strong bootstrap support. Both the ML and MP tree were More >

Abstract Cell lines with high passage numbers exhibit alterations in cell morphology and functions. In the present work, C2C12 skeletal muscle cells with either low (<20) or high (>60) passage numbers (identified as lC2C12 or h-C2C12, respectively) were used to investigate the apoptotic response to H2 O2 as a function of culture age h-C2C12. We found that older cultures (h-C2C12 group) were depleted of mitochondrial DNA (mtDNA). When we analyzed the behavior of Bad, Bax, caspase-3 and mitochondrial transmembrane potential, we observed that cells in the h-C2C12 group were resistant to H2 O2 induction of More >
