Young mice fed diets deficient in pyridoxine or fed desoxypyridoxine after the inoculation of the pneumonia virus of mice were more resistant to infection than well nourished controls. The susceptibility of young mice to PVM increased with the duration of pyridoxine administration after inoculation. Dietary protein restriction when pyridoxine was provided did not affect the susceptibility of mi...

This paper describes some recent research on PVM (Parallel Virtual Machine). One of the new features added in PVM 3.0 is multiprocessor integration. This is the ability to run PVM applications on the nodes of several diierent distributed memory multiprocessors as though they constitute one large parallel computer. We describe how multiprocessor integration is accomplished in PVM 3.0 and illustr...

Meningeal (MM) and perivascular macrophages (PVM) constitute major populations of resident macrophages in the CNS that can be distinguished from microglial cells. So far, there is no direct evidence that demonstrates a possible role of MM and PVM in the CNS during normal or pathologic conditions. To elucidate the role of the MM and PVM during CNS inflammation, we have developed a strategy using...

This report describes the implementation of the Common Message Passing Layer (CML) for the SISCI PC cluster, as far as developed further from the previous report D.2.1.1, and presents the results achieved with this implementation. As CML functionality is integrated into an existing implementation of PVM, we will achieve immediate full functionality of the PVM system over SCI as soon as the amal...

Red blood cell (RBC) invasion and parasitophorous vacuole (PV) formation by Plasmodium falciparum are critical for the development and pathogenesis of malaria, a continuing global health problem. Expansion of the PV membrane (PVM) during growth is orchestrated by the parasite. This is particularly important in mature RBCs, which lack internal organelles and no longer actively synthesize membran...

The supercritical CO2-based technologies have been widely used in the formation of drug and/or polymer particles for biomedical applications. In this study, nanoparticles of poly-(methyl vinyl ether-co-maleic anhydride) (PVM/MA) were successfully fabricated by a process of solution-enhanced dispersion by supercritical CO2 (SEDS). A 2 factorial experiment was designed to investigate and identify...

Evaluating the in vivo accuracy of magnetic resonance phase velocity mapping (PVM) is not straightforward because of the absence of a validated clinical flow quantification technique. The aim of this study was to evaluate PVM by investigating its precision, both in vitro and in vivo, in a 1.5 Tesla scanner. In the former case, steady and pulsatile flow experiments were conducted using an aortic...

UNLABELLED Pneumonia virus of mice (PVM) is a natural rodent pathogen that replicates in bronchial epithelial cells and reproduces many clinical and pathological features of the more severe forms of disease associated with human respiratory syncytial virus. In order to track virus-target cell interactions during acute infection in vivo, we developed rK2-PVM, bacterial artificial chromosome-base...

This paper describes a portable message passing and process management platform for multithreaded applications. PT-PVM is based on the PVM system and provides message passing and process management facilities at the thread level for a cluster of workstations running the UNIX operating system without changing the PVM system. Moreover PT-PVM introduces advanced programming abstractions like gener...

Although PVM was developed to use a network of heterogeneous UNIX computers as a single large parallel computer, it has become an interface for portable programming even on MPP's. We present PVM performance results for a massively parallel transputer system with up to 512 processors. In comparison to an implementation of the same application in the native transputer operating system Parix, we r...
