Root exudation in a sloping Moso bamboo forest in relation to fine root biomass and traits.

Exudation by fine roots generally varies with their morphological traits, but the effect of belowground resource availability on the root exudation via root morphological traits and biomass remains unknown. We aimed to determine the effects of morphological and physiological traits on root exudation rates and to estimate stand-scale exudation (Estand) by measuring the mass, length, and surface area of fine roots in a Moso bamboo forest. We measured root exudation as well as morphological and physiological traits in upper and lower plots on a slope with different belowground resource availability.

Sensitivity-Based Calibration of the Soil and Water Assessment Tool for Hydrologic Cycle Simulation in the Cong Watershed, Vietnam.

For better water resources management in quality and quantity, an accurate model is needed for simulating the hydrologic cycle and water quality dynamics at a watershed scale. In this study, a semi-distributed hydrologic model, the Soil and Water Assessment Tool (SWAT), was applied for hydrologic cycle assessment in the Cong Watershed, Vietnam. After model-output and accuracy-based sensitivity analyses were conducted without and with observation data, respectively, model parameters were calibrated and validated using meteorological and runoff data observed between 1961 and 1975.

Impact of laparoscopic surgery on survival of patients with small bowel adenocarcinoma and peritoneal metastasis.

The feasibility of laparoscopic surgery for peritoneal metastasis is still controversial. A 42-year-old male presenting with bloody stool underwent small intestinal fiberscopic examination. The biopsied specimens pathologically demonstrated adenocarcinoma of the upper jejunum.

Long-term outcome of laparoscopic resection for stage IV colorectal cancer.

Laparoscopic surgery is recommended as an initial stage IV colorectal cancer therapy. A 57-year-old male with sigmoid colon cancer and two hepatic metastases underwent laparoscopic sigmoidectomy with lymph adenectomy. He was orally administered postoperative Tagafur/Uracil/leucovorin therapy for 10 months.

Pelvic peritonectomy without intraperitoneal chemotherapy for localized peritoneal carcinomatosis.

Aim: This study assessed the feasibility of pelvic peritonectomy for carcinomatosis localized in the pelvic cavity. The survival and clinical benefits were examined, especially in colorectal cancer.

Patients And Methods: Seventeen patients underwent pelvic peritoneal resection for peritoneal dissemination localized in the pelvis (10 colorectal, six ovarian, one cervical cancer).

Cerebral microbleeds in Binswanger's disease: a gradient-echo T2*-weighted magnetic resonance imaging study.

We investigated the incidence and the number of microbleeds (MBs) on T2*-weighted gradient-echo magnetic resonance imaging in 30 Binswanger's disease (BD) patients with diffuse white matter lesions and a varying degree of lacunar infarction, 51 multiple lacunar stroke (MLS) patients with multiple lacunar infarction and no or mild white matter lesions, and 59 elderly controls. MBs were found in 23 (77%) patients with BD, 26 (51%) patients with MLS, and 5 (8%) controls, and the incidence and the number of MBs were significantly greater in the BD group compared with MLS and control groups. Patients with BD had a more widespread location of MBs.
