Bovine Serum Albumin Molecularly Imprinted Electrochemical Sensors Modified by Carboxylated Multi-Walled Carbon Nanotubes/CaAlg Hydrogels.

In this paper, sodium alginate (NaAlg) was used as functional monomers, bovine serum albumin (BSA) was used as template molecules, and calcium chloride (CaCl2) aqueous solution was used as a cross-linking agent to prepare BSA molecularly imprinted carboxylated multi-wall carbon nanotubes (CMWCNT)/CaAlg hydrogel films (MIPs) and non-imprinted hydrogel films (NIPs). The adsorption capacity of the MIP film for BSA was 27.23 mg/g and the imprinting efficiency was 2.73. The MIP and NIP hydrogel film were loaded on the surface of the printed electrode, and electrochemical performance tests were carried out by electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV) using the electrochemical workstation. The loaded MIP film and NIP film effectively improved the electrochemical signal of the bare carbon electrode. When the pH value of the Tris HCl elution solution was 7.4, the elution time was 15 min and the adsorption time was 15 min, and the peak currents of MIP-modified electrodes and NIP-modified electrodes reached their maximum values. There was a specific interaction between MIP-modified electrodes and BSA, exhibiting specific recognition for BSA. In addition, the MIP-modified electrodes had good anti-interference, reusability, stability, and reproducibility. The detection limit (LOD) was 5.6 × 10-6 mg mL-1.

Is a polymorphism in 10q25 associated with non-syndromic cleft lip with or without cleft palate? A meta-analysis based on limited evidence.

Non-syndromic cleft lip with or without cleft palate (NSCL/P) is one of the most common defects in the human facial structure. A polymorphism, rs7078160 in 10q25, has been reported to be involved in susceptibility to the condition but results remain conflicting. To address this we did a meta-analysis of 7 eligible studies. Two authors independently collected information from the papers, and fixed effects or random effects models were used to calculate the combined estimates of risk. The pooled results showed that rs7078160 on 10q25, the minor allele A, had a higher risk of NSCLP than the major allele G (OR: 1.32, 95% CI: 1.18 to 1.47). Overall, the results showed that the 10q25 rs7078160 polymorphism was associated with a risk of NSCL/P.

[Application of free anterolateral thigh flap for the treatment of burn scar carcinoma].

OBJECTIVE: To discuss the therapeutic effect of free anterolateral thigh flap for the treatment of burn scar carcinoma. METHODS: From Jun. 2005 to Feb. 2013, 10 cases with burn scar carcinoma at craniofacial area and extremities underwent radical excision and transposition of free anterolateral thigh flaps for the leaving wounds. RESULTS: The flaps in 10 cases survived completely and primarily without any complications. The operation time was 7 hours in average. The patients were followed up for 5 months to 2 years (1 year, in average) without no recurrence and no functional morbidity in donor sites. The cosmetic results were satisfactory in all the cases, even with hair growth in 6 cases. CONCLUSION: The free anterolateral thigh flap is suitable for the treatment of burn scar carcinoma.
