Multiple lineage-specific surface molecules have recently been defined on human T lymphocytes. Although some of these appear during late intrathymic ontogeny and are maintained on all peripheral T cells (T3), others (T4, TS) arise earlier in differentiation and are selectively expressed on functional subpopulations of human T lymphocytes (1-3). In the case of the 20,000-mol wt T3 surface molecu...

‘‘Tunable’’ fluids such as magnetorheological ~MR! and electrorheological ~ER! fluids are comprised of paramagnetic or dielectric particles suspended in a low-viscosity liquid. Upon the application of a magnetic or electric field, these fluids display a dramatic, reversible, and rapid increase of the viscosity. This change in viscosity can, in fact, be tuned by varying the applied field, hence ...

A total of 48 neonatal pigs were used to determine whether intubation with colostrum or medium-chain triglyceride (MCT) would enhance glucose homeostasis and survival. Pigs were removed from the sow prior to nursing and alloted to three treatment groups. Fasted pigs received only water for 30 h, whereas those allotted to supplemented groups received either 30 ml of colostrum or 15 ml of MCT at ...

Intradermal injection of purified protein derivative produced typical delayed type hypersensitivity reactions in five healthy human subjects. The major subpopulations of lymphocytes and certain accessory cells were located in frozen sections of biopsies of the lesions with monoclonal antibodies and immunohistochemical staining. The densities (expressed as number/unit area for comparison) of the...

The effectiveness of conjugated linoleic acid (CLA) as a weight-loss nutraceutical continues to be debatable, suggesting that there may be value in exploring the physiological effects of the lesser-known isomers. The effects of the minor isomer, trans-8, cis-10 (t8, c10)-CLA, in the form of an equimolar mixture with the cis-9, trans-11 (c9, t11) isomer, on body weight and body composition, circ...

A previously healthy 42-year-old black woman had posterior midthoracic tenderness; a right-sided paraspinous soft-tissue mass; and progressive, bilateral leg weakness . On examination she was afebrile and had reduced strength in both lower extremities. Chocolatecolored pus was aspirated from the paraspinous soft-tissue mass. The results of a complete blood cell count and CSF analysis were norma...

Patients with T gamma lymphocytosis are a heterogeneous group, clearly distinguishable from other patients with chronic T lymphoproliferative disorders and usually without proven malignancy. We have attempted in vitro cloning of lymphocytes from three patients with an expansion of phenotypically and functionally different types of T gamma cells. One had T3+ B73.1+ T4 T8+ OKM1+ T gamma cells exe...

Four novel Epstein-Barr virus (EBV)-carrying T-cell lines, designated SIS, AIK-T8, AIK-T4, and SKN, were established from peripheral blood lymphocytes (PBL) of patients with severe chronic active EBV infection, in the presence of interleukin-2 and 4-deoxyphorbol ester. AIK-T8 and -T4 were derived from a single patient. Cell marker and genotype analyses showed that SIS, AIK-T8, and AIK-T4 had ma...
