Activation-induced deaminase (AID) initiates the secondary antibody diversification process in B lymphocytes. In mammalian B cells, this process includes somatic hypermutation (SHM) and class switch recombination (CSR), both of which require AID. AID induces U:G mismatch lesions in DNA that are subsequently converted into point mutations or DNA double stranded breaks during SHM/CSR. In a physiological context, AID targets immunoglobulin (Ig) loci to mediate SHM/CSR. However, recent studies reveal genome-wide access of AID to numerous non-Ig loci. Thus, AID poses a threat to the genome of B cells if AID-initiated DNA lesions cannot be properly repaired. In this review, we focus on the molecular mechanisms that regulate the specificity of AID targeting and the repair pathways responsible for processing AID-initiated DNA lesions.

Bile duct injury repair — earlier is not better

Bile duct injury is a common complication of cholecystectomy. The timing of bile duct injury repair remains controversial. A recent review conducted in France reported 39% complications and 64% failure after immediate repair in 194 patients compared with 14% complications and 8% failure after late repair in 133 patients. A national review of 139 consecutive early repairs conducted at five hepatopancreaticobiliary centers in Denmark reported 4% mortality, 36% morbidity, and 42 restrictures (30%) at a median follow-up of 102 months, and only 64 patients (46%) demonstrated uneventful short-term and long-term outcomes. Most patients with bile duct injury present with bile leak and sepsis; thus, early repair is not recommended. Percutaneous drainage of bile and endoscopic stenting are the mainstays of treatment of bile leak because they convert acute bile duct injury into a controlled external biliary fistula. The ensuing benign biliary stricture should be repaired by a biliary surgeon after a delay of 4–6 weeks once the external biliary fistula has closed.

In order to determine the effect of Natural Pozzolan (NP) content on the mechanical properties and durability characteristics on Engineered Cementitious Composites (ECC) as repair material. This study focused on the evaluation of the most factors influencing compatibility between the repair material and the base concrete including mechanicals properties such as, compressive and flexural strengths, elastic modulus, capillary absorption and drying shrinkage. The experimental results showed that natural pozzolan reduces the compressive strength and the flexural strength of ECC at all ages. The elastic modulus of ECC was remarkably lower than that of normal-strength concrete. This lower Young’s modulus is desirable for repair concrete, because it prevents the stresses induced by restrained shrinkage. In addition, the incorporation of high-volume natural pozzolan decreases significantly the coefficient of capillary absorption at long term and increases the drying shrinkage. Generally, based on the results obtained in the present experimental investigation, ECC can be used effectively as an overlay material over existing parent concrete.
