BACKGROUND: Laparoscopic cholecystectomy (LC) for symptomatic gallstone disease is one of the most common surgical procedures. Concomitant common bile duct (CBD) stones are detected with an incidence of 4-20% and the ideal management is still controversial. The frequent practice is to perform endoscopic sphincterotomy pre-operatively (POES) followed by LC, to allow subsequent laparoscopic or open exploration if POES fails. However, POES has shown different drawbacks such as need for two hospital admissions, need of two anesthesia inductions, higher rate of pancreatitis, and longer hospital stay...

A new nickel(II) porphyrin complex, [NiII(porp)] (1) has been synthesized and characterized by 1H NMR, 13C NMR and mass spectrometry analysis. This NiII porphyrin complex 1 catalyzed quantitatively the epoxidation reaction of a wide range of olefins with meta-chloroperoxybenzoic acid (MCPBA) under mild conditions. Reactivity and Hammett studies, H218O-exchange experiments, and the use of PPAA (peroxyphenylacetic acid) as a mechanistic probe suggested that participation of multiple active oxidants NiII-OOC(O)R 2, NiIV-Oxo 3, and NiIII-Oxo 4 in olefin epoxidation reactions by nickel porphyrin complex is markedly affected by solvent polarity and concentration and type of substrate...

A copper-catalyzed regiocontrolled three-component reaction afforded diversified 4-aminoquinolines using nitriles, diaryliodoniums, and ynamides. The C7-substituted regioisomers were formed regioselectively when meta-substituted phenyliodonium salts were used. [1,3] N-to-C rearrangement of the products to quinolin-4-ylmethanesulfonamides and simultaneous deprotection of benzyl and sulfonamide group were newly developed. Finally, antimalarial CK-2-68 was successfully prepared.

Many high-resolution patterning techniques have been developed to realize nano- and microscale applications of electric devices, sensors, and transistors. However, conventional patterning methods based on photo or e-beam lithography are not employed to fabricate optical elements of high aspect ratio and a sub-100 nm scale due to the limit of resolution, high costs and low throughput. In this study, covalent bonding-assisted nanotransfer lithography (CBNL) was proposed to fabricate various structures of high resolution and high aspect ratio at low cost by a robust and fast chemical reaction...

The rapid influx of married immigrant women from low-income Asian countries is a concern in South Korea, Japan, and Taiwan. In South Korea, 1 in 10 couples includes a Korean man and a migrant woman, increasing the need for prenatal and postnatal care interventions. Studies published in English or Korean after 2000 were retrieved from 8 databases and reviewed via a systematic review and meta-analysis of the effectiveness of prenatal and postnatal psychosocial and educational interventions in Korea. Of 3583 records, 10 studies (1 randomized controlled trial [RCT] and 9 non-RCTs) involving 408 married immigrant women fulfilled the inclusion criteria...

Immune checkpoint inhibitors (ICIs) have emerged as a new treatment option for patients with advanced non-small-cell lung cancer (NSCLC). Some studies with ICIs in NSCLC suggested that smoking history was associated with improved survival outcomes. We conducted this meta-analysis to investigate if survival benefits of ICIs in patients with advanced NSCLC are different according to smoking status. Electronic databases were searched for eligible studies. We included randomized controlled trials with the data of survival outcomes and extracted progression-free survival (PFS) or overall survival (OS) stratified by smoking status...

A coding region polymorphism exists in the TP53 gene (Pro47Ser; rs1800371) in individuals of African descent, which reduces p53 tumor suppressor function in a mouse model. It has been unclear whether this functionally significant polymorphism alters cancer risk in humans. This analysis included 6907 women with breast cancer and 7644 controls from the AMBER, ROOT, and AABC consortia. We used multivariable logistic regression to estimate associations between the TP53 Pro47Ser allele and overall breast cancer risk...
