Diagnostic yield of a novel tracer 68Ga-citrate in sarcoidosis patients.

Background: Sarcoidosis is a granulomatous disease of unknown origin. Conventional laboratory and imaging modalities may lead to equivocal conclusions for sarcoidosis diagnosis. 68Ga-citrate PET/CT has been utilized in the diagnosis of inflammatory and infectious diseases due to its beter  performance.

Diagnostic yield of the Kveim test in sarcoidosis patients.

Background And Aim: Sarcoidosis is a granulomatous disorder of unknown etiology characterized by the existence of non-caseating granulomatous inflammation. Diagnosis can be challenging due to the presence of comprehensive clinical, laboratory, and radiologic manifestations. We have evaluated the diagnostic yield of the Kveim test and compared this test with the other conventional laboratory modalities.

Assessment of the Role of Nuclear ENDOG Gene and mtDNA Variations on Paternal Mitochondrial Elimination (PME) in Infertile Men: An Experimental Study.

In humans and most animals, maternal inheritance of mitochondria and mitochondrial DNA (mtDNA) is considered as an universal assumption. Recently, several lines of evidence suggest that different species seem to employ distinct mechanisms to prevent the inheritance of paternal mtDNA. There are few studies in the literature on the molecular basis of sperm mtDNA elimination in mammals and paternal mtDNA transmission in humans.
