Article Abstract
(Objective) Although laparoscopic radical cystectomy (LRC) is becoming a standard care for invasive and high-risk non-invasive bladder cancer in Japan, the data about mid-and long-term oncological outcome is still lacking. We previously reported our initial experience of LRC compared to open radical cystectomy. In this study, we evaluated mid-term oncological outcome for LRC by updating our clinical data. In addition, we evaluated the effect of technical modifications for LRC. (Patients and methods) From March 2005 to September 2015, 60 patients underwent LRC at our institution. Treatment outcomes including surgical and oncological outcomes were analyzed. We also assessed the effect of technical modifications between first 30 cases and second 30 cases as to blood loss, operating time and complication rate. (Results) The overall complication rate was 47%, including 18% serious complications (Clavien score 3 or greater). The 5-year recurrence-free survival, cancer-specific survival, and overall survival were 56.2%, 74.4%, and 63.6%, respectively. The recurrence occurred in 19 (32%) cases, including distant metastasis in 12 (20%) cases, local recurrence in 6 (10%) cases, and both in 1 (2%) cases. As for the effect of technical modifications for LRC, the blood loss decreased and postoperative recovery was faster in second 30 cases. (Conclusion) These results indicate that LRC could be performed safely with acceptable oncological outcomes.

The sesquiterpene (+)-valencene, with its flavor and diverse biological functions, holds promise for applications in the food, fragrance, and pharmaceutical industries. However, the low concentration in nature and high cost of extraction limit its application. This study aimed to construct a microbial cell factory to efficiently produce (+)-valencene.

Molecular recognition mediated by s-hole interactions is enhanced as the electrostatic potential at the σ-hole becomes increasingly positive. Traditional methods to strengthen σ-hole donor ability of atoms such as halogens often involve covalent modifications, such as, introducing electron-withdrawing substituents (neutral or positively charged) or electrochemical oxidation. Metal coordination, a relatively underexplored approach, offers a promising alternative.

Unlabelled: Remote polar regions offer unique opportunities and significant challenges for antimicrobial resistance research in a near-pristine environment. While core microbiology techniques continue to have an important role in supporting environmental research, the severe cold climate presents considerable challenges to laboratory research. We explore adaptations required for core bacteriology investigations in polar regions on an unsupported remote expedition c.

Background: Results of the National Lung Screening Trial create the potential to reduce lung cancer mortality, but community translation of lung cancer screening (LCS) has been challenging. Subsequent policies have endorsed informed and shared decision-making and using decision support tools to support person-centered choices about screening to facilitate implementation. This study evaluated the feasibility and acceptability of LuCaS CHOICES, a web-based decision aid to support delivery of accurate information, facilitate communication skill development, and clarify personal preferences regarding LCS-a key component of high-quality LCS implementation.

Aims: To assess and compare the effectiveness of pharmacological and cognitive-behavioral modalities-behavioral methods (BM), nitrous oxide inhalation sedation (NOIS), and premedication with Diazepam-for alleviating anxiety during dental treatment, using completed treatment sessions and adverse outcomes as indicators.
Methods And Results: For 239 patients (515 dental records), 18-53 y/o, who underwent dental treatments under anxiety reduction measures, sessions under NOIS were categorized as "nitrous group" (456 sessions) versus premedication with Diazepam or behavioral strategies (control, 59 sessions). Outcomes were completed treatment sessions considering demographic and clinical parameters, and adverse outcomes during and between sessions.
