Establishment of a Live-Imaging Analysis for Polarized Growth of Conchocelis in the Multicellular Red Alga .

A wide range of tip-growing cells in plants display polarized cell growth, which is an essential cellular process for the form and function of individual cells. Understanding of the regulatory mechanisms underlying tip growth in terrestrial plants has improved. Cellular processes involved in tip growth have also been investigated in some algae species that form filamentous cells, but their regulatory mechanisms remain unclear.

Upper gastrointestinal pathophysiology due to mouse malaria ANKA infection.

Background: Epigastric pain, vomiting, and other gastrointestinal problems are among the most important symptoms of malaria infection as they suggest the possibility that the condition is serious. Pathophysiologies such as gastric mucosal changes and delayed gastric emptying have been reported in serious cases of malaria infection. However, it is unclear whether or not pathophysiological involvement of the upper gastrointestinal tract occurs in ANKA (PbA)-infected mice.

[Evaluation of the characteristics of tuberculosis patients in Ashikaga Red Cross Hospital, Tochigi Prefecture, Japan (2007-2011)].

Objective: To retrospectively evaluate the trends in tuberculosis characteristics among patients attending the Ashikaga Red Cross Hospital, Tochigi Prefecture, Japan, between January 2007 and December 2011, and to compare this trend with that observed globally.

Methods: In total, 273 newly reported tuberculosis patients attending the Ashikaga Red Cross Hospital were examined from January 2007 to December 2011 in terms of age, sex, mortality during tuberculosis treatment, race (Japanese or non-Japanese), nationality of non-Japanese patients, pulmonary (including sputum positivity and/or cavity formation in the lungs) or extrapulmonary tuberculosis, latent tuberculosis infection, residential areas of patients, and diseases coexisting with tuberculosis.

Results: Among the 255 Japanese tuberculosis patients, 202 patients were aged over 60 years, while the 18 non-Japanese patients were aged less than 50 years.

Schistosoma mekongi and Schistosoma japonicum: Differences in the distribution of eggs in the viscera of mice.

The difference in the distribution of Schistosoma eggs in the viscera has not been clearly elucidated in the two closely related species Schistosoma japonicum and Schistosoma mekongi. In this study, we quantitatively compared the distribution of eggs in mice infected with the two species. In S.

High susceptibility of Neotricula aperta gamma-strain from Krakor and Sdau in Cambodia to Schistosoma mekongi from Khong Island in Laos.

Neotricula aperta gamma-strain snails collected from Krakor and Sdau in Cambodia were found to have the same or higher susceptibility to Schistosoma mekongi as N. aperta originally isolated from Khong in Laos. Infection rates of N.
