The antifungal drugs of the echinocandin family show high efficacy against Aspergillus fumigatus. However, their paradoxical effect, which restores fungal growth at drug concentrations, and emergence resistant strains necessitate improvements. We identified 13 fluoroquinolone compounds from a chemical library containing 10,000 that potentiate activity caspofungin. Among them, NE-E07 significantly enhanced echinocandins A. fumigatus, including strains, without potentiating other families like...
Aims Programmed death‐ligand 1 (PD‐L1) expression is a predictive biomarker for adjuvant immunotherapy and has been linked to poor differentiation in lung adenocarcinoma. However, its prevalence prognostic role the context of novel histologic grade not evaluated. Methods We analysed cohort 1233 patients with resected adenocarcinoma where PD‐L1 immunohistochemistry (22C3 assay) was reflexively tested. Tumour correlated new standardized International Association Study Lung Cancer (IASLC)...
The prognostic role of EGFR mutations remains controversial. We aimed to evaluate the mutation in consideration IASLC histological grade patients with resected early-stage lung adenocarcinoma.A total 3297 stages I-IIA adenocarcinoma who had tests between January 2014 and December 2019 at Samsung Medical Center, Seoul, Korea were included. Recurrence-free survival (RFS) was compared by status (EGFR-M+ versus EGFR-WT) (G1, G2 G3). Cox proportional hazards models used estimate adjusted HRs...

TO THE EDITOR: Pneumocystis jiroveci is a potential cause of virulent pneumonia in patients with impaired immunity, especially cell-mediated immunity. Increasing emphasis on prophylaxis using trimethoprim-sulfamethoxazole (TMP-SMX) has resulted decreasing incidence (PJP) some diseases, such as human immunodeficiency virus (HIV) infection and lymphocytic leukemia. However, there are no standard guidelines for PJP other lymphoproliferative disorders. We report case that occurred after course...

A 55-year-old woman who had received an implantable left ventricular assist device 3 months earlier presented with dyspnea and a low-flow alarm of the device. Computed tomography log-file analysis system suggested inflow cannula obstruction. Since patient cardiogenic shock due to pump failure, venoarterial extracorporeal membrane oxygenation (ECMO) was initiated. With ECMO, surgical exchange considered. However, obstruction spontaneously resolved without intervention. It turned out that...

Abstract The antifungal drugs of the echinocandins family showed high activity against A. fumigatus . However, have a paradoxical effect and it is necessary to improve echinocandins. To develop new drug that improves echinocandins, we performed screening using chemical library consisting 8,000 unique chemicals with 0.5µg/ml caspofungin. From library, found fluoroquinolone compounds activate caspofungin no was detected. 50 from had synergistic on among them, 16 were derivative low when...

However, has difficulties in achieving successful results patients with persistent or long-standing Currently, the gold standard surgical (the Cox maze III procedure). because requires sternotomy and extracorporeal cardiopulmonary bypass been associated surgery-related complications, minimally invasive (totally thoracoscopic) epicardial-endocardial (hybrid) procedures have...
최근 관심이 높아지고 있는 공동체주택은 일반주택과는 다른 독특한 계획과정을 갖고 있다. 그러나 주택의 계획과정에 초점을 맞춘 연구는 부족한 실정이다. 따라서 본 연구에서는 추진 방식에 따른 비교하고 개선의 방향을 제시하였다. 대면 인터뷰를 통해 진행되었으며, 도면 자료 수집이 가능한 수도권 16가구를 사례로 선정하였다. 기획 과정을 개념 단계, 기본 세부 단계로 나누어 분석한 결과는 다음과 같다. 첫째, 기존 커뮤니티에서 추진하는 주택계획은 초기부터 구성원들의 충분한 논의를 거쳐 결정된다. 초기 컨셉 단계부터 전문가를 통한 기술 지원이 필요하다. 둘째, 민간기업이 구성원을 모집하는 개념계획은 사전에 기업에서 진행하고, 기본계획 단계에서는 입주자가 워크숍을 참여한다. 워크숍은 결속력을 기르는 데 도움이 되지만, 워크숍 비용이 집값을 상승시킨다는 문제가 셋째, 공공부문에서 주택은 구성원의 잦은 변경, 주민 니즈가 계획과정에서 제대로 반영되지 않는 등의 결과에 정책적 시사점은...
