background: hypocalcemia is a well-recognized complication after total thyroidectomy. hypovitaminosis d may have additional effect in the development of hypocalcemia. this study aimed to determine the effect of total thyroidectomy on postoperative serum calcium in patients with and without hypovitaminosis d. methods: this prospective study was performed on patients who underwent total thyroidec...

In this paper, a two-surfaces sliding mode controller (TSSMC) is proposed for the voltage tracking control of a two input DC-DC converter in application of electric vehicles (EVs). The imperialist competitive algorithm (ICA) is used for tuning TSSMC parameters. The proposed controller significantly improves the transient response and disturbance rejection of the two input converters while p...

In this paper, transient solution of two dimensional asymmetric thermal and mechanical stresses for a hollow cylinder made of piezoelectric material is developed. Transient temperature distribution, as function of radial and circumferential directions and time with general thermal boundary-conditions, is analytically obtained, using the method of separation of variables and<br...

many experimental studies have reported behavioral improvement after transplantation of peripheral nerve tissue into the contused spinal cord, even in large animals. the safety of this treatment in human remains unknown. in this translational phase 1 study, safety of peripheral nerve grafting for chronic spinal cord injuries and possible outcomes are being reported. twelve complete motor spinal...

conclusions by employment of gene optimization strategies, use of viral-based vectors and suppression of plant-derived gene silencing effect, efficient transient expression of hcvcp in tobacco with proper antigenic properties could be possible. background hepatitis c virus (hcv) is major cause of liver cirrhosis in humans. hcv capsid (core) protein (hcvcp) is a highly demanded antigen for vario...

This investigation deals with transient analysis of cold standby system with n units . Chapman-Kolmogorov equations are developed for repair facility with two repairmen and solved by using matrix technique. Availability and reliability factors have been obtained with probability of the system. A particular case has also been discussed.

conclusions fap is an accurate, reliable, and noninvasive approach that can also be combined with other metabolic biomarkers to comprehensively detect and quantify hepatic steatosis. results the difference in fap was significant (p < 0.001) between chb-only patients and chb patients with hepatic steatosis. the cytokeratin 18 fragment (ck18-m65) level was significantly higher in chb patients wit...

normal 0 false false false en-us x-none ar-sa back ground: considering the high prevalence of congenital hypothyroidism (ch) in isfahan, the intelligence quotient (iq) of children with ch and the effect of diagnostic and treatment variables on it were investigated during the ch screening program. materials and methods: a total of 120 children in three studied groups were studied in this compara...
