OBJECTIVE to determine the prevalence and epidemiological factors associated with hepatitis (HCV) coinfection in human immunodeficiency virus (HIV) patients from Curitiba and the metropolitan region. METHODS a study with 303 HIV+ patients, mean age 41.2 years (18-73); 50.5% men, followed at the Hospital de Clínicas, Universidade Federal do Paraná, between April 2008 and March 2009. Clinical a...

Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 10, No. 12, December 2004 2257 species can cause disease (symptomatic infection) and death. C. felis and C. meleagridis infections showed low oocyst shedding (all seven patients had low to moderate oocyst loads in samples). On the contrary, C. parvum produced similar clinical manifestations but showed higher oocyst shedding; 46% had high to ...

BACKGROUND Dengue fever/dengue haemorrhagic fever is prevalent in Thailand, where all serotypes are found and the dominant serotype has changed irregularly. Although almost all primary infections present with slight symptoms or are asymptomatic, little is known about the infectiousness of dengue fever. METHODOLOGY A mathematical model of the transmission for dengue virus was constructed cover...

In a single-hop network with multiple relays, selecting a single node to aid in the transmission between a source and a destination outperforms both traditional orthogonal transmissions and distributed space-time codes. The usage of multiple hops will further improve the wireless communication. This paper presents an energy efficient selection of cooperative nodes with respect to their geograph...

We present a detailed ns-2 [1] based simulation analysis on four of the prominent mobile ad hoc network routing protocols: Dynamic Source Routing (DSR) protocol [2], Associativity-Based Routing (ABR) protocol [3], FlowOriented Routing Protocol (FORP) [4] and the Routelifetime Assessment Based Routing (RABR) protocol [5]. The simulations were conducted with and without transmission power control...

Hepatitis B virus (HBV) is an important threat to global public health. Despite the availability of safe and effective prophylactic vaccines, the existence of a large reservoir of chronic carrier patients impedes the eradication of this virus; therefore, HBV-related diseases still rank ninth on the global ranking of causes of mortality (1). Moreover, HBV is considered the fifth most important i...

The emergence of diseases such as Zika and Ebola has highlighted the need to understand the role of sexual transmission in the spread of diseases with a primarily non-sexual transmission route. In this paper we develop a number of low-dimensional models which are appropriate for a range of assumptions for how a disease will spread if it has sexual transmission through a sexual contact network c...

copper sulfate was used as a precursor to prepare cuo nanoparticles in reverse micelles (o/w microemulsion).  this is a technique which allows the preparation of ultrafine metal oxide nanoparticles within the size ranging from 50 to 60 nm. the preparation of nano copper (ii) oxide studied was investigated in the inverse microemulsion system. therefore the nucleation of metal particles proceeds ...
