Objective: To investigate the association of the mitochondrial DNA region np16181-16193 variations with type 2 diabetes mellitus (T2DM).
Methods: Blood samples of 199 unrelated T2DM patients and 205 normal controls were collected to detect the mitochondrial DNA region np16181-16193 variations by PCR and sequencing, and to analyze the association of the variations with the major clinical symptoms.
Results: The mitochondrial DNA np16181-16193 region is a hypervariable area, with several polymorphisms. Four types of np16181-16193 region variations were found only in T2DM. The 1-hour postprandial blood glucose (P1BG) in the T2DM individuals with np16181-16193 region variations was significantly higher than those without variations (P<0.05), while there was no significant difference in other biochemical parameters (P>0.05).
Conclusion: The mitochondrial DNA np16181-16193 variations could not be regarded as a risk factor for T2DM.

Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (CNS). The etiology of MS remains elusive, with a complex interplay of genetic and environmental factors contributing to its pathogenesis. Recent studies showed mitochondrial DNA (mtDNA) as a potential player in the development and progression of MS.

Background: The risk of mosquito-borne disease transmission is increasing in temperate climates with the colonization and proliferation of the Asian tiger mosquito vector Aedes albopictus and the rapid mass transport of passengers returning from tropical regions where viruses are endemic. The prevention of major Aedes-borne viruses heavily relies on the use of insecticides for vector control, mainly pyrethroids. In Europe, only deltamethrin is authorized.

Background: Mitochondrial transcription elongation factor (TEFM) is a recently discovered factor involved in mitochondrial DNA replication and transcription. Previous studies have reported that abnormal TEFM expression can disrupt the assembly of mitochondrial respiratory chain and thus mitochondrial function. However, the role of TEFM on Uterine corpus endometrial carcinoma (UCEC) progression remains unclear.

However, upon UV irradiation low-fidelity translesion polymerases: Polη, Polζ and Rev1, participate in an error-free replicative bypass of UV-induced lesions in mtDNA. We analysed how translesion polymerases could function in mitochondria.

The Anopheles maculipennis complex consists of several mosquito species, including some primary malaria vectors. Therefore, the presence of a species in a particular area significantly affects public health. In this study, 1252 mosquitoes were collected in northern Italy, representing four identified species of the Anopheles maculipennis complex (Anopheles daciae sp.
