Effect of low temperature stress treatment in five selected clones of Camellia sinensis (T-17, TV-19, TV-25, TV-29, TV-30) was found to be significant. Guaiacol Peroxidase (GPX) decreased with decreasing temperature. PPO decreased with decreasing temperature showing highest activities at 20°C in all clones. CAT activit ies decreased in T-17, TV29, and TV-30 with decrease in temperature with exc...
Two human monocyte subsets from the peripheral blood of healthy donors have been isolated in greater than 90% purity by countercurrent centrifugal elutration and human serum albumin gradients and their functional capabilities have been assessed. We have demonstrated that one subset ("regular" monocytes, RM) showed intense cytoplasmic peroxidase staining and contained substantial peroxidase acti...
The great diversity of arthropod body plans, together with our detailed understanding of fruit fly development, makes arthropods a premier taxon for examining the evolutionary diversification of developmental patterns and hence the diversity of extant life. Crustaceans, in particular, show a remarkable range of morphologies and provide a useful outgroup to the insects. The amphipod crustacean P...
An enzyme immunoassay was developed for the detection of human immunoglobulin M (IgM) antibody to different flavivirus antigens. The IgM antibody of human sera was selectively bound to anti-IgM antibody-coated solid-phase plates. Flavivirus IgM antibodies were then detected by use of various enzyme-labeled antigens. The flavivirus antigens (dengue type 2 virus, West Nile virus, and tick-borne e...
Hashimoto's encephalopathy (HE) is a steroid-responsive relapsing neuropsychiatric disorder associated with high titers of antithyroid antibody with or without thyroid dysfunction. We report a case of HE in a 78 year old female who developed sudden onset behavioral abnormalities associated with choreiform movement of extremities. All causes of vascular, infective, metabolic, autoimmune, paraneo...
The attachment of mouse immunoglobulin G (IgG) and anti-mouse IgG antibodies onto carbon nanotubes (CNTs), using either non-covalent or covalent means was investigated. The resultant CNTs were characterised using a variety of techniques including enzymelinked and fluorescence-linked immunoassays, UV-visible-NIR and Raman spectroscopy, transmission electron microscopy and cyclic voltammetry. TEM...
We present a case of a false-positive anti-myeloperoxidase (MPO) antibody result on an ELISA in a patient with anti-thyroid microsomal antibody (TMA)-positive hypothyroidism. A 41-year-old woman presented with dyspnea on exertion. The initial evaluation revealed pericardial effusion associated with hypothyroidism. In addition, microscopic hematuria with normal renal function and positive cytopl...
One hundred and fifteen serum samples from healthy laboratory personnel and 50 consecutive samples from 19 patients with anamnestic clinical signs of toxoplasmosis were assayed by four laboratories for the presence of immunoglobulin M antibodies to Toxoplasma gondii by an indirect enzyme-linked immunosorbent assay (ELISA), an antibody capture assay with peroxidase-labeled toxoplasma antigen, an...
Expansion microscopy (ExM) is a methodology which increases the imaging resolution of sample through expansion prior to optical by crosslinking it hydrogel, digesting it, and swelling gel, thereby expanding sample. Though many variations ExM have been created, all these rely on labeling with fluorescent markers. Here we use enzyme-linked antibody markers generate chromogenic staining proteins i...
