During the excavations of the XIX century Meadowlark cemetery (Manhattan, Kansas, US), samples of sediments were taken from around five skeletons, and analyzed to detect intestinal parasites. No helminth eggs were found, but immunological ELISA tests for Entamoeba histolytica were positive in three samples. The immunological techniques have been successfully used in paleoparasitology to detect ...

Reported here are the assay results, using the anaesthetized rat preparation of Lai (1964), of plasma from patients known or suspected to have peptide-secreting adenomata and these are compared with assays carried out on plasma from patients whose clinical history excluded such pathology. It is suggested that these demonstrate that this technique is of diagnostic value in this condition and tha...

Clinical, pathological, and immunological analysis of 20 patients with ocular adnexal lymphoid disease has demonstrated several parameters which are useful for distinguishing malignant from benign lesions. Patients in the fourth or fifth decade of life presenting with an acute history of pain, oedema, epiphora, double vision, and ptosis, with a mass localised in the lacrimal gland area, are mor...

Generating tier 2 HIV-neutralizing antibody (nAb) responses by immunization remains a challenging problem, and the immunological barriers to induction of such responses with Env immunogens remain unclear. Here, some rhesus monkeys developed autologous tier 2 nAbs upon HIV Env trimer immunization (SOSIP.v5.2) whereas others did not. This was not because HIV Env trimers were immunologically silen...

The formation of immunological synapses between T cells and APCs, as well as the functions associated with this structure, like cytokine secretion and the lysis of infected cells, are critical processes in the immune response. The T cell cytoskeleton is involved in these activities and this has been the subject of numerous studies in recent years. Although the importance of the T cell actin net...

The mammalian immune system and the nervous system coevolved under the influence of infection and sterile injury. Knowledge of homeostatic mechanisms by which the nervous system controls organ function was originally applied to the cardiovascular, gastrointestinal, musculoskeletal, and other body systems. Development of advanced neurophysiological and immunological techniques recently enabled t...

Plasma exchange was used for many years as the method of extracorporeal removal of antibodies and/or immune complexes that may be involved in the pathogenesis of renal diseases. Recently low-density lipoprotein (LDL)-apheresis and immunoadsorption were also introduced into nephrological practice. LDL-apheresis, designed originally as a rescue treatment for refractory hyperlipidaemia, appeared a...

The objective of this study was to identify and characterize the immunological and molecular aspects of Human Enterovirus (HEV) associated with aseptic meningitis cases in São Paulo State, Brazil. Clinical samples (cerebrospinal fluid CSF, stool and sera) were analyzed from 21 viral meningitis suspected cases collected in the period from 1998 to 1999. The isolated virus were identified as belon...

Glycine N-methyltransferase activity has been examined in a number of fetal and adult organs, as well as in several rodent hepatomas, using both enzymatic and immunological techniques. In fetal rabbit liver, the activity first appears at a low level at about 20 days postfertilization and rises to high levels after birth, reaching maximum in the adult liver. In fast-growing hepatomas, the activi...
