A simple micro motion picture apparatus has been developed which is so inexpensive to construct and to operate that it can be used regularly for bacteriological research. With this equipment about 6000 feet of film representing 600 hours of photography have been made of B. shigae growing upon various solid media. These pictures illustrate the principal phenomena accompanying the development of ...

Galtier 1 and Pasteur 2 demonstrated the infectiousness of rabies. Negri ~ next described the characteristic inclusions in the ganglion cells, and Babes, 4 J. Koch, 5 Volpino, 6 Proescher, 7 and others found minute granular or pleomorphic particles in the central nervous system of animals infected with ra~bies. Remlinger, s Poor and St einhardt, 9 Bertarelli and Volpino ~° demonstrated the filt...

Conventional and modified membrane bioreactors (MBRs) are increasingly used in small-scale wastewater treatment. However, their widespread applications are hindered by their relatively high cost and operational complexity. In this study, we investigate a new concept of wastewater treatment using a nonwoven fabric filter bag (NFFB) as the membrane bioreactor. Activated sludge is charged in the n...

INTRODUCTION Hypertension is associated with microcirculatory disturbance, and erythrocyte deformability is a major determinant of the microcirculation. However, impairment of erythrocyte deformability in hypertensive patients in relation to antihypertensive treatment is unclear. The present study aimed to investigate this impairment in hypertensive patients under treatment using a highly sensi...

A perfluorochemical blood substitute emulsified with Pluronic F-68 has been shown to improve the filterability of deoxygenated sickle red cells. We questioned whether some of the effect was independent of oxygen loading and studied the influence of Fluosol DA (Green Cross, Osaka, Japan) and Pluronic on the rheology and adhesion of sickle red cells saturated with oxygen and carbon monoxide. A 5-...

The sexual blood stage of the human malaria parasite Plasmodium falciparum undergoes remarkable biophysical changes as it prepares for transmission to mosquitoes. During maturation, midstage gametocytes show low deformability and sequester in the bone marrow and spleen cords, thus avoiding clearance during passage through splenic sinuses. Mature gametocytes exhibit increased deformability and r...

Splenic filtration of infected red blood cells (RBCs) may contribute to innate immunity and variable outcomes of malaria infections. We show that filterability of individual RBCs is well predicted by the minimum cylindrical diameter (MCD) which is calculated from a RBC's surface area and volume. The MCD describes the smallest diameter tube or smallest pore that a cell may fit through without in...

Procaine hydrochloric acid, a cationic anesthetic, although unable to prevent the effect of calcium ionophore A231 87 on erythrocytes, inhibited the discocyteechinocyte transformation, increased viscosity, and decreased filterability of red cells undergoing AlP depletion. The effects were abolished by washing ATP-depleted, procaine HCI-treated red cells prior to these determinations. Procaine H...
