The mitochondrial DNA copy number (mtDNA-CN) is a surrogate measure of mitochondrial function and altered mtDNA-CN reflects the oxidant-induced cell damage. A previous study by our group demonstrated that a reduction in the renal mtDNA-CN is implicated in the pathogenesis of diabetic nephropathy (DN), a leading cause of end-stage renal disease in diabetic patients. In the present study, it was investigated whether the mtDNA-CN in the peripheral blood may be utilized as a biomarker for DN in type 2 diabetes (T2D) patients...

BACKGROUND: Microalbuminuria represents vascular and endothelial dysfunction. Thyroid hormones can influence urine albumin excretion (UAE) as it exerts crucial effects on the kidney and on the vascular system. This study explores the relationship between serum thyrotropin (TSH) and UAE in euthyroid patients with diabetes. METHODS: 433 patients with Type 1 or 2 diabetes were included in this retrospective cross-sectional study. Data included anthropometric measurements and biochemical parameters from diabetes clinic...

BACKGROUND: Iliac vein injury associated with pelvic fracture due to blunt trauma is an uncommon and difficult diagnosis but a life-threatening condition which often requires an emergent management. Although open repair has been traditionally used as the treatment of choice in unstable patients, it is controversial, given the difficulty injured vessel exposure in patients with significant retroperitoneal hematoma as well as tamponade effect loss associated to laparotomy. We present a challenging case of iliac vein laceration successfully treated by placement of a self-expanding covered stent...

In patients suspected to have myelodysplastic syndrome (MDS), especially in those patients without cytogenetic abnormalities or blast excess, accurate morphologic review by an expert hematopathologist and meticulous exclusion of other secondary causes of myelodysplasia are vital to establish the diagnosis. Errors in diagnosis can lead to dangerous consequences such as the administration of hypomethylating agents, lenalidomide, or even the use of intensive chemotherapy or allogeneic hematopoietic cell transplantation in patients who do not have an underlying MDS or even a malignant hematopoietic process...

Malignant pleural mesothelioma (MPM) is a rare neoplasm. It predominantly affects elderly individuals aged over 70 years presenting with a unilateral pleural tumor usually associated with previous asbestos exposure. The respiratory symptoms are associated with ipsilateral pleural involvement with concomitant pleural effusions. The diagnosis of MPM is established by the morphologic and immunohistochemical features of a cytologic specimen. MPM can present as three histologic subtypes: epithelioid, sarcomatoid, or biphasic...

We investigate the magnetism and the magnetization blocking of a series of [Fe2Dy2(OH)2(teaH)2(RC6H4COO)6] complexes, where teaH3 = triethanolamine and R = meta-CN (1), para-CN (2), meta-CH3 (3), para-NO2 (4) and para-CH3 (5), by combining ab initio calculations and EPR measurements. BS-DFT calculations show that in all compounds the Fe-Fe exchange interaction is antiferromagnetic and by far stronger than Fe-Dy and Dy-Dy ones. As a result, the lowest two exchange doublets probed by EPR mostly originate from the Ising interaction of Dy ions in all compounds...

PURPOSE: Circumferential speckle tracking carotid artery strain is a novel method of quantifying vessel wall stiffness. We hypothesized that carotid wall stiffness would be associated with carotid intimal medial thickening (a medial process associated with risk factors), but not coronary artery disease (an intimal process). METHODS: Bilateral carotid artery ultrasound was conducted on outpatients who had previously undergone elective coronary angiography. Mean carotid artery far wall circumferential strain (FWCS) was assessed for correlations with coronary angiographic stenosis, cardiac risk factors, carotid intima-media thickness (CIMT), and carotid plaque...

Background: A new paradigm is emerging in which mobility and cognitive impairments, previously studied, diagnosed, and managed separately in older adults, are in fact regulated by shared brain resources. Deterioration in these shared brain mechanisms by normal aging and neurodegeneration increases the risk of developing dementia, falls, and fractures. This new paradigm requires an integrated approach to measuring both domains. We aim to identify a complementary battery of existing tests of mobility and cognition in community-dwelling older adults that enable assessment of motor-cognitive interactions...

The mammalian ovary is a highly dynamic organ, in which proliferation and differentiation occur constantly during the entire life span, particularly in camels that are characterized by a follicular wave pattern and induced ovulation. Granulosa cells are the main cells of mature follicles. Two distinct cell types, namely, the mural and cumulus granulosa cells are distinguished on the basis of antral fluid increase. The multipotency of follicular fluid and the luteinizing cell were recently demonstrated. However, reports regarding the plasticity of cumulus cells are lacking...

BACKGROUND AND AIMS: Pancreatic ductal adenocarcinoma (PDAC) is a heterogeneous disease with variable presentations and natural histories of disease. We hypothesized that different morphologic characteristics of PDAC tumors on diagnostic computed tomography (CT) scans would reflect their underlying biology. METHODS: We developed a quantitative method to categorize the PDAC morphology on pre-therapy CT scans from multiple datasets of patients with resectable and metastatic disease, and correlated these patterns with clinical/pathologic measurements...

Formyl glycals are the versatile synthetic intermediates and can serves as precursor for the synthesis of various C and N-nucleosides. Due to the presence of electron donating and electron withdrawing character on formyl sugars which makes the molecule more susceptible to nucleophilic attack. Utilizing same strategy, we propose the synthesis of diversified C -nucleosides ( 3 - 14 ) by reaction with N , N dinucleophiles. These nucleoside analogs were than tested against viral, bacterial and fungal strains.
