Two hundred four strains of Streptococcus pneumoniae isolated in Hong Kong from January 1993 to May 1995 were analyzed for their antibiotic susceptibilities and epidemiological patterns. The ages of the patients from whom the strains were isolated from 1 month to 93 years (median, 53 years); the male-to-female ratio was 2.8, with a predominance of males in(More)
Time-lapse or longitudinal fluorescence microscopy is broadly used in cell biology. However, current available time-lapse fluorescence microscopy systems are bulky and costly. The limited field-of-view (FOV) associated with the microscope objective necessitates mechanical scanning if a larger FOV is required. Here we demonstrate a wide FOV time-lapse(More)
We describe a case of delayed presentation of attempted suicide with a nail gun that penetrated both the right and left ventricle. Nearly invisible entry point of the nail did not reflect the gravity of the injury. A prompt and accurate history along with chest X-ray and bedside transthoracic echocardiography facilitated localization of the nails and helped(More)
We present here one of the first research efforts conducted at Jet Propulsion Laboratory (JPL) to implement on a single chip (Xilinx Zynq) all the functionality necessary to control a NASA instrument, namely a Fourier Transform Spectrometer (FTS) that is proposed for deployment on future missions to Jupiter's moon Europa. The system requires custom logic to(More)
BACKGROUND Adverse neurological sequelae are a major cause of morbidity and mortality after coronary artery bypass (CABG) surgery, due to manipulation of an atherosclerotic aorta. The purpose of this study is to measure the impact of intraoperative epi-aortic scanning in reducing neurologic sequelae after CABG, and the patient subgroups that are benefitted(More)
OBJECTIVES A portable suction drainage device for patients undergoing thoracic surgical procedures was introduced into our service in January 2010. Patients who met strict discharge criteria were allowed to continue their treatment at home with the device. They were monitored in a designated follow-up clinic. Data were collected to identify the impact of(More)
