Rapid identification of viruses has important implications for medical healthcare. Current methods for identification and quantification of particular virus are time consuming and often expensive. Therefore, demand for sensitive and accurate viral biosensors with rapid detection systems is increasing. A hand held biosensing device would give fast, reliable results for identifying and quantitating the number of virus particles in a sample. Techniques currently being applied to achieve this aim include electrochemical biosensors, based on amperometric, potentiometric and impedance measurement, optical biosensors using surface plasmon resonance (SPR), optical fibers and piezoelectric biosensors based on microcantilevers. Future research also looks to the use of nanoparticles and novel nanomaterials as alternate recognition surfaces for use in a variety of sensor formats.

The ability to recognize invading viral pathogens and to distinguish their components from those of the host cell is critical to initiate the innate immune response. The efficiency of this detection i...
Infectious disease surveillance is hindered by several factors, including limited infrastructure and geographic isolation of many resource-poor regions. In addition, the complexities of sample acquisi...
Current antivirals effectively target diverse viruses at various stages of their life cycles. Nevertheless, curative therapy has remained elusive for important pathogens, such as human immunodeficienc...
Biosensors use biological elements to detect or quantify an analyte of interest. In bioprocessing, biosensors are employed to monitor key metabolites. There are two main types: fully biological system...
Human immunodeficiency virus type 1 (HIV-1), the causative agent of acquired immunodeficiency syndrome, encodes four accessory genes, one of which is viral protein U (Vpu). Recently, the study of Vpu ...
Severe acute respiratory syndrome (SARS) is a new emerging infectious disease. Its pathogen is a newly discovered coronavirus (SARS-CoV). The clinical course can be classified to 3 stages:...
Since the infectious aetiology of AECOPD has been suggested to vary according to geographical region, the primary purpose of this study (which will be conducted in several countries in Asi...
This protocol will enable IRB (institutional review board) review of proposed research using human samples and data collected under the terminated NIH studies 04-EI-0065 and 96-EI-0096. Da...
Human papillomavirus (HPV)-infection belongs to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men (MSM) are strongly associated with a higher pr...
The purpose of this study is to demonstrate that viral specific T-cells (a type of white blood cell) can be generated from an unrelated donor and given safely to patients with viral infect...
Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.
The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease.
Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.
Organizations representing designated geographic areas which have contracts under the PRO program to review the medical necessity, appropriateness, quality, and cost-effectiveness of care received by Medicare beneficiaries. Peer Review Improvement Act, PL 97-248, 1982.
INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).
Health care (or healthcare) is the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in humans. Health care is delivered by practitioners in medicine, chiropractic, dentistry, nursing, pharmacy, a...
