PURPOSE OF REVIEW: This analysis discusses the comparative effectiveness and cost-effectiveness of vitreoretinal interventions, measured in quality-adjusted life years (QALYs) and percentage patient value (PPV gain, or improvement in quality of life and/or length of life). The material is relevant since the Patient Protection and Affordable Care Act enacted by Congress with the support of the President has emphasized the critical importance of patient-based preferences. RECENT FINDINGS: The majority of preference-based, comparative effectiveness and cost-effectiveness vitreoretinal interventions assessed in the US healthcare literature are Value-Based Medicine analyses, thus comparable...

BACKGROUND: Outpatient laparoscopic cholecystectomy (OPLC) developed in the United States and other developed countries as one of the fast-track surgeries performed in ambulatory centers. However, this practice has not been installed as a routine practice in the major general hospitals and medical centers in China. We designed this case-control study to evaluate the feasibility, benefits, and safety of OPLC. METHODS: Two hundred patients who had received laparoscopic cholecystectomy for various benign gallbladder pathologies from April 2007 to December 2008 at Jinling Hospital of Nanjing University School of Medicine were classified into two groups: OPLC group (100 patients), and control group (100), who were designated for inpatient laparoscopic cholecystectomy (IPLC)...

5'-Methylthioadenosine/S-adenosylhomocysteine nucleosidase (MTAN) is important in a number of cellular functions such as polyamine biosynthesis, methionine salvaging, biological methylation, and quorum sensing. The nucleosidase is found in many microbes but not in mammalian systems, thus making MTAN a broad-spectrum antimicrobial drug target. Substrate binding and catalytic residues were identified from the crystal structure of MTAN complexed with 5'-methylthiotubercidin [Lee, J. E., Cornell, K. A., Riscoe, M...

High DDT concentrations and o,p'-DDT/p,p'-DDT ratios observed in the air over Taihu Lake, a lake near Shanghai, China, led us to suggest that current use of dicofol in the area north of the lake was the main source of the measured DDTs. To examine this hypothesis, samples of commercially available formulated dicofol in China were collected in 2003 to measure the impurities of DDT related compounds (DDTs). The o,p'-DDT/p,p'-DDT ratio in the samples was 7.0, close to the observed value in the air over Taihu Lake...

Using broken-symmetry unrestricted density functional theory quantum mechanical (QM) methods in concert with mixed quantum mechanics/molecular mechanics (QM/MM) methods, the hydroxylation of methane and substituted methanes by intermediate Q in methane monooxygenase hydroxylase (MMOH) has been quantitatively modeled. This protocol allows the protein environment to be included throughout the calculations and its effects (electrostatic, van der Waals, strain) upon the reaction to be accurately evaluated. With the current results, recent kinetic data for CH3X (X = H, CH3, OH, CN, NO2) substrate hydroxylation in MMOH (Ambundo, E...
