Protein interactions are crucial components of all cellular processes. An in-depth knowledge of the full complement of protein interactions in a cell, therefore, provides insight into the structure, properties and functions of the cell and its components. An accurate and comprehensive protein interaction network is, thus, an invaluable framework to study protein regulation in disease. Although ...

Two methods of performing serological screening tests for syphilis are compared. One consisted of the Venereal Diseases Reference Laboratory (VDRL) slide test, the cardiolipin Wassermann reaction (CWR), and the Reiter protein complement fixation test (RPCFT) performed manually; the other was a fully automated system using two Technicon AutoAnalyzers (AAII), one for the automated reagin test (AR...

BACKGROUND Trypanosoma cruzi is a protozoan parasite and an etiological agent of Chagas disease. There is a wide variability in the clinical outcome of its infection, ranging from asymptomatic individuals to those with chronic fatal mega syndromes. Both parasite and host factors, as well as their interplay, are thought to be involved in the process. OBJECTIVES To evaluate the resistance to co...

The complement system, unlike the coagulation system, was largely characterized by in-vitro techniques which did not make use of genetically deficient plasmas. The existence of the genetically deficient plasmas. The existence of the genetically deficient subjects therefore has served largely to increase our knowledge of the in-vivo role of complement. At the present time its clearest role is in...

The complement system is a group of about 35 soluble and cell-surface proteins which interact to recognize, opsonize and clear or kill invading micro-organisms or altered host cells (e.g. apoptotic or necrotic cells). Complement is a major part of the innate immune system. Recognition proteins such as C1q, MBL (mannan-binding lectin) and ficolins bind to targets via charge or sugar arrays. Bind...

In the best articles, generally those dealing with basic Chromosome Puffs research, the combination of depth and accessibility is impressive. One on Hox genes introduces the notion of The Science Times Book of Genetics a conserved body plan among species, illustrating the Edited by Nicholas Wade point with the fauna of Star Trek, and continues with New York: The Lyons Press (1999). 256 pp. an e...

conclusions considering that neuronal function highly depends on environmental conditions, any adverse alteration may affect the function and morphology of neurons. in this regard, our results showed the adverse effects of protein malnutrition on the morphology of the purkinje cells of cerebellum. results the low-protein group did not gain weight as much as control group (p < 0.05). the diamete...

Loa loa is a filarial nematode that infects humans. The adults live in subcutaneous tissues and produce microfilariae that live for several weeks in the blood circulation in order to be transmitted to another person via blood meals of a dipterian vector. As microfilariae live in continuous contact with plasma, it is obvious that they evade the complement system. We studied markers of complement...

INTRODUCTION We previously identified tick salivary lectin pathway inhibitor (TSLPI) in Ixodes scapularis, a vector for Borrelia burgdorferi sensu stricto (s.s.) in North America. TSLPI is a salivary protein facilitating B. burgdorferi s.s. transmission and acquisition by inhibiting the host lectin complement pathway through interference with mannose binding lectin (MBL) activity. Since Ixodes ...

mumps is an acute contagious viral disease that usually manifests as inflam¬mation of the parotid glands. the disease may be associated with symptoms such as parotitis, orchitis and meningoencephalitis. 85% of cases occur in children under 15 years of age. the disease is rare below two years but increases with age, reaching a maximum at 5 to 9 years. some studies in iran showed that the highest...
