CDSimple™ hCG Chemiluminescent ELISA Kit

A cationic Gemini surfactant with a benzene ring (abbreviated as C-14-CGB) was synthesized in 2 steps with aniline, epichlorohydrin, and N,N-dimethyltetradecylamine as starting materials. This product was characterized using mass spectroscopy and nuclear magnetic resonance (H-1 NMR). The critical micelle concentration (CMC) and surface tension ((cmc)) of C-14-CGB were measured from 298 to 313K and thermodynamic parameters of micellization were calculated. The results showed that the CMC and (cmc) were 1.269 x 10(-3) molL(-1) and 38.33mNm(-1) at 298K, respectively. Moreover, upon increasing the temperature, the CMC increases, (cmc) decreases, the maximum surface adsorption capacity ((max)) decreases, and the minimum molecular area (A(min)) increases. The emulsified asphalt test showed that C-14-CGB is a slow-breaking asphalt emulsifier exhibiting excellent emulsifying ability.

Objective To evaluate the clinical efficacy of two types of condom uterine balloon tamponade systems, namely Chhattisgarh condom balloon device "CG balloon (CGB)" having a central drainage channel as well as indigenous tying system to fasten condom to the catheter and conventional condom uterine balloon device (C-UBT) as a second-line intervention in post-partum haemorrhage (PPH). Materials and Methods The present non-randomised prospective case series was carried out from December 2014 to September 2016 and included 60 women having PPH which was refractory to first-line management and who were treated with either of the two condom balloon tamponade devices prepared on spot. Women with allergy to latex, retained placenta, uterine rupture, anomaly, genital infection and/or malignancy were excluded. Case report forms were filled for all participants and analysed. Primary outcome was arrest of haemorrhage, and one of the secondary outcomes was cost and consistency of the devices. Results CGB was used in 46 and C-UBT in 14 women. The overall success rate was 98.33%. The mean blood loss was 1417 mL. Women of C-UBT group had greater blood loss, higher inflation volume and delays due to technical issues (OR 7.6). CGB was cheaper and more consistent than C-UBT by omitting the use of suture material. Conclusion CGB and conventional condom balloon tamponade both are easy to use, feasible and efficacious for control of PPH, but CGB condom balloon device has the advantage of a central drainage lumen for real-time assessment of blood loss and therefore early corrective action.
