Perioperative Outcomes and Feasibility of Single-Stage Laparoscopic Common Bile Duct Exploration (LCBDE) and Cholecystectomy With Internal Endo-Biliary Drainage for Management of Concomitant Cholelithiasis With Choledocholithiasis: A Report From a Tertiary Care Hospital.

Introduction: Managing choledocholithiasis alongside cholelithiasis has seen significant evolution, presenting options such as single-stage cholecystectomy with common bile duct (CBD) exploration, or a two-stage procedure involving endoscopic retrograde cholangiopancreatography (ERCP) performed before or after cholecystectomy. Evidence from Western settings may not fully capture the unique disease burden and demographic characteristics prevalent in developing countries. Laparoscopic common bile duct exploration (LCBDE) is more commonly performed in the Indian subcontinent compared to Western centers due to limited access to advanced procedures and specialized instrumentation for complex ERCP cases.

Ancillary Ligand-Promoted Charge Transfer in Bis-indole Pyridine Ligand-Based Nickel Complexes.

There is growing demand for the utilization of first-row transition metal complexes in light-driven processes instead of their conventional noble metal counterparts due to the greater sustainability of first-row transition metal complexes. However, their major drawback is the ultrafast lifetime of the electronic excited states of these first-row transition metal complexes, particularly those of d square-planar systems such as Ni(II) complexes, wherein low-lying metal-centered (MC) states provide the deactivation pathway. To increase the excited-state lifetime and broaden their applications, it is important to develop sterically bulky, strong field ligands with low-lying π* orbitals and a highly σ-donating nature to augment the energy of MC states.

Catalyst-Free Diborylation and Silaboration of Azoarenes: A Simple Photoinduced Approach.

The diborylation of the N=N double bond of azoarenes has been achieved using a commercially available diboron reagent, Bcat [bis(catecholato)diboron].
