Mediators of Inflammation

There are many chemical mediators of inflammation. Although the exact function and the source of some chemical mediators are unclear, certain generalizations are, however, possible. It should also be noted that there could be some unidentified chemical mediators of inflammation. Some of the important mediators of inflammation include histamine, serotonin, lysosomal enzymes, PGs, LTs, PAFs, ROS, NO, HOCl, various cytokines, the kinin system, the coagulation fibrinolysis system, and the...

Conclusions and Future Directions

For the present time, it is my opinion that the cardiac troponins are destined to stay. Only time will tell whether a better successor will emerge when it does, numerous studies will have to validate its utility and provide the appropriate level of evidence-base. Several generations of research and assay refinements have validated the cardiac troponins as a diagnostic and prognostic marker for the ACS. For the future, it is anticipated that more sensitive assays will emerge that might be able...

Leptin and the Anorexia of the Elderly

Several cross-sectional and longitudinal studies have described a decline in food intake with aging in healthy elderly subjects 80-83 . This physiological decrease in food intake with age was defined as anorexia 80-83 . In the NHANES III an average decline in energy intake of about 1000 kcal day (men) and 500 kcal day (women) between the age of 20 and 75 years was described 84 . Aging was also associated with a decline in total energy expenditure that is accounted not only by a decline in...

Leptin and Bone Metabolism

Mice Leptin Level

Leptin has been proposed as mediating the protective effects of obesity on the skeleton similarly to traditional factors, such as mechanical loading and increased levels of estrogens and insulin 117 . Leptin shows both a peripheral and positive action on bone as well as a central and negative control of bone metabolism 118-122 . Considering the conflicting and sometimes contradictory data published in the literature, it remains difficult to draw a clear picture harmonizing these dual eVects of...

Human Prion Disease Surveillance

History of Prion Disease Transmission The first evidence that the infectious agent of the transmissible spongiform encephalopathy, commonly called prion disease, could be naturally transmitted through the ingestion of contaminated food stuff dramatically came from the observation that a neurodegenerative disease called kuru selectively aVected a tribe of New Guinea that practiced ritualistic endogenous cannibalism 51 . Tribe members were likely exposed to contaminated flesh from a subject...

Species as the analyte-specific antibodies in an attempt to mop up'' any HAs present in serum. In a recent opinion piece, Ismail highlighted the reports of serious consequences incurred due to interferences in immunoassays and has called for a radical approach to eliminate this interference using polyethylene-glycol (PEG) precipitation as a preanalytic step before analyses 208 . Rheumatoid factors (RF) are a group of heterogeneous immunoglobulins whose common property is the reaction with the...

Ayurvedic Tips Fot Controling Troponin

Not come into play giving the skeleton more weight bearing strength 120 . It may be concluded that there is a balance between these two pathways, with a predominance of peripheral and positive effects of leptin only in conditions of central leptin resistance, as in obesity, or when serum leptin levels rise above a threshold. This hypothesis appears supported by recent observations in hemodialysis patients in which bone mineral density (BMD) was positively associated with leptin only when...

Clinical Laboratory Tools to Diagnose Inflammation

It is evident from the preceding discussion that many biological molecules are involved in the pathobiology of inflammation. At bedside, it is relatively simple to diagnose acute inflammation generally characterized by rubor, tumor, calor, dolor, and functiolaesa (redness, swelling, heat, pain, and loss of function, respectively). Because these acute inflammatory events are visible and easily assessed, no specific laboratory tests may be required to measure the presence or absence of...

New Approaches for Detection of PSA

Identification of Novel PSA-Binding Ligands Immunoassays are very sensitive and specific facilitating accurate measurement of individual proteins in the presence of more than 1 million-fold excess of other proteins 159 . The use of monoclonal antibodies has made it possible to develop assays that differentiate between variants of the same protein, but apparently because antibodies recognize epitopes on the surface of proteins, recognition of differences in internal structures that are not...
