Early COVID-19 presence and related deaths in Turkish cities can be explained by their international trade volume. Trade with China has a higher impact on the pandemic against total of cities. The ordering between imports, exports varies depending stage pandemic. As were sealed off many countries, continuing country increasing case numbers. Key Words: COVID-19, City-level Data Analysis, Interna...

The Ciona intestinalis voltage sensor-containing phosphatase (Ci-VSP) shares high homology with the phosphatidylinositol phosphatase enzyme known as PTEN (phosphatase and tensin homologue deleted on chromosome 10). We have taken advantage of the similarity between these proteins to inquire about the coupling between the voltage sensing and the phosphatase domains in Ci-VSP. Recently, it was sho...

Homogenates of the Aplysia nervous system contain protein kinase activities sensitive to cAMP, cGMP, and Ca2+/calmodulin. The cAMP- and cGMP-dependent activities are either soluble enzymes or are only loosely bound to membranes, since they can be detected only in crude but not in washed membrane fractions, and are present in 20,000 or 100,000 X g supernatants prepared from homogenates. In contr...

Dopamine's effect on calcium influx into the bursting neuron, R15, of Aplysia californica was tested by tail current measurements and by measurement of absorbance of intracellular Arsenazo III, a calcium-sensitive indicator. Slow outward tail currents were elicited by subthreshold depolarization in voltage clamp and were demonstrated to be dependent upon transient increases in intracellular cal...

PURPOSE To identify the correlation of the model for end-stage liver disease (MELD) scores with the assessment of the risk of hepatic function after hemihepatectomy in patients with hepatocellular carcinoma (HCC) related to hepatitis B virus (HBV). METHODS A case-control study was performed based on data for 141 consecutive patients who underwent curative right hepatic resection between Janua...

Two R factors, one (R15) conferring resistance to streptomycin and sulfonamide (SM(r)SU(r)) and the other (222/R3) to streptomycin, sulfonamide, and chloramphenicol (SM(r)SU(r)CM(r)), were transferred to a Proteus mirabilis strain, and deoxyribonucleic acid (DNA) extracted from these strains was subjected to density-gradient centrifugation. R15-DNA formed a single satellite band at a density of...

The impulse oscillation system (IOS) measures respiratory impedance (Zrs) in terms of resistance (Rrs) and reactance (Xrs) at multiples of 5 Hz. These measurements can be used clinically to help diagnose and monitor respiratory disorders, independent of effort. There is, as yet, no information on reference values for IOS in Iranian adolescents.The predictive equation for resistance and impedanc...

BACKGROUND Most patients with hepatocellular carcinoma (HCC) have underlying liver disease, therefore, precise preoperative evaluation of the patient's liver function is essential for surgical decision making. METHODS We developed a grading system incorporating only two variables, namely, the serum albumin level and the indocyanine green retention rate at 15 minutes (ICG R15), to assess the p...

Hepatocellular carcinoma (HCC) is the most common type of liver cancer. Hepatic resection has long been considered a main treatment option for HCC, but the high rate of recurrence after hepatic resection remains a problem that impacts the prognosis and survival of patients with HCC. Thus, clarifying the factors for survival and risk factors for tumor recurrence after hepatic resection is crucia...

OBJECTIVES This retrospective study was a comparative analysis of sensitivity of impulse oscillometry and spirometry techniques for use in a mixed chronic obstructive pulmonary disease group for assessing disease severity and inhalation therapy. METHODS A total of 30 patients with mild-to-moderate chronic obstructive pulmonary disease were monitored by impulse oscillometry, followed by spirom...
