Bollgard cotton is the trademark given to a number of varieties of cotton bio-engineered to produce an insecticidal protein from Bacillus thuringiensis (Bt). When produced by the modified cotton plants, this protein controls certain lepidopterous cotton insect pests. Commercially available since 1996, these cotton varieties are purchased under a license(More)
The objective of this study was to determine the efficiency of an argon laser in polymerizing a light-cured orthodontic adhesive. Metal brackets were bonded to 185 premolars, divided into 5 different protocol groups of 37 each as follows: light 40-second buccal, light 40-second lingual, laser 5-second lingual, laser 10-second lingual, and laser 15-second(More)
Recombinant human alpha-interferon is now under intensive investigation as therapy for chronic Type B hepatitis. Recent reports have suggested that prolonged alpha-interferon therapy may induce autoimmune reactions. We have evaluated the problem of autoimmunity related to alpha-interferon therapy by testing for 15 different antibodies in the sera of 31(More)
The natural killer (NK) cell activity of mice in the peritoneal cavity is very low or undetectable and testing peritoneal NK cells is a useful model for studying the influence of activating substances upon local injection. Injection of tumor necrosis factor (TNF) at doses of 10-200 ng caused a marked activation of NK cell activity which was maximal after 24(More)
Human PBMC from HIV-1-infected individuals produced ex vivo in response to vesicular stomatitis virus only low amounts of IFN-alpha. This impairment was significant as early as Walter Reed (WR) stage 2; at WR stage 4-5, the production was almost zero. At WR stage 2 of infection, IFN-alpha mRNA was exclusively found in association with polyribosomes,(More)
OBJECTIVES This study aims to validate the ability to perform depression screening with the patient health questionnaire (PHQ)-2 and PHQ-9 depression modules in a busy, outpatient practice, and to evaluate the prevalence of depression among lung cancer outpatients at our institution. METHODS In 2010, 64 patients in a thoracic malignancy clinic completed(More)
The present study investigates the potential capacity of the immunostimulant Corynebacterium parvum (C.p.) to induce tumor necrosis factor-alpha (TNF-alpha) in human peripheral blood mononuclear cells (PBMC) and blood monocytes (BMo) in vitro. Both at the mRNA and protein level, stimulation of PBMC and BMo upon C.p. induces TNF-alpha. Compared to the(More)
The production of interferon (IFN) from cultured peripheral blood mononuclear cells (PBMC) after virus or mitogen stimulation was evaluated in 141 patients positive for antibodies to human immunodeficiency virus type 1 (HIV-1). IFN-alpha production by PBMC of patients at Centers for Disease Control (CDC) stage II (Walter Reed [WR] 1) was comparable to that(More)
Sulphoevernan is a sulphated alpha-1----3, 1----4 polyglucan (Mr 20,000) with a helical structure. This compound effectively inhibits both human immunodeficiency virus type 1 (HIV-1) and type 2 infection of cells in vitro at concentrations around 0.5 micrograms/ml. Moreover, the compound completely inhibits HIV-1-induced syncytium formation at a(More)
