Aptamer-antibody Dual Probes on Single-walled Carbon Nanotube Bridged Dielectrode: Comparative Analysis on Human Blood Clotting Factor.

Aptamer-antibody Dual Probes on Single-walled Carbon Nanotube Bridged Dielectrode: Comparative Analysis on Human Blood Clotting Factor. Int J Biol Macromol. 2019 Nov 16;: Authors: Yao J, Li S, Zhang L, Yang Y, Gopinath SCB, Lakshmipriya T, Zhou Y Abstract Haemophilia is a blood clotting disorder known as 'Christmas disease' caused when the blood has defect with the clotting factor(s). Bleeding leads various issues, such as chronic pain, arthritis and a serious complication during the surgery. Identifying this disease is mandatory to take the necessary treatment and maintains the normal clotting. It has been proved that the level of factor IX (FIX) is lesser with haemophilia patient and the attempt here is focused to quantify FIX level by interdigitated electrode (IDE) sensor. Single-walled carbon nanotube (SWCNT) was utilized to modify IDE sensing surface. On this surface, dual probing was evaluated with aptamer and antibody to bring the possible advantages. The detection limit with antibody was found to be 1 pM, while aptamer shows 100 fM. Further, a fine-tuning was attempted with sandwich pattern of aptamer-FIX-antibody and antibody-FIX-aptamer and compared. Specific elevation of detection with 10 folds was noticed and displayed the detection at 100 fM in both sandwich patterns. In addition, FIX was detected in the diluted human serum by aptamer-FIX-antibody sandwich, it was found that FIX detected from the dilution factor 1:640. A novel demonstration ...

A 25-year-old man living in Tehran (a non-endemic and very rare area for schistosoma) suffers from symptoms such as hematuria with suprapubic pain, dysuria, fever, nausea and vomiting. Urine analysis showed a lot of red blood cells, after using cystoscopy of the area and receiving a bladder biopsy, a definitive diagnos...

We report outcomes of our initial experience with LP in 38 children from 2 months of age. Materials and Methods From June 2015 to December 2017 38 children aged 2-60 months (mean age 1.7 years) underwent LP for correction of PUJ obstruction. The mean pre operative anteroposterior diameter of the renal pelvis (APD) was 43,5mm and all patients had hydronephrosis (APD 21.4-76 mm) and obstructed curve on diuretic renogram. Anderson-Hynes pyeloplasty was the performed technique. Results are reported. Results Mean operative time was 107 minutes (70-180) with no conversion to open procedure. Pain control was needed mainly in the ...
