A431 human epidermoid carcinoma cells monophenotypically express the placenta! alkaline phosphatase (PLAP)-like enzyme shown by its catalytic and antigenic characteristics, properties which are shared by the Nagao isozyme. More specifically, it is L-leucine sensitive just as is the rare placenta! D-variant of PLAP and the testicular heat-stable enzyme. Collectively, these are all referred to as...

We have evaluated the capacity of dendritic cells to function as antigen-presenting cells (APCs) for influenza and have examined their mechanism of action. Virus-pulsed dendritic cells were 100 times more efficient than bulk spleen cells in stimulating cytotoxic T lymphocyte (CTL) formation. The induction of CTLs required neither exogenous lymphokines nor APCs in the responding T cell populatio...

Carbohydrates have been suggested to account for some IgE cross-reactions between various plant, insect, and mollusk extracts, while some IgG antibodies have been successfully raised against plant glycoproteins. A rat monoclonal antibody raised against elderberry abscission tissue (YZ1/2.23) and rabbit polyclonal antiserum against horseradish peroxidase were screened for reactivity in enzyme-li...

Bromelain belongs to a group of protein digesting enzymes obtained commercially from the fruit or stem of pineapple. Fruit bromelain and stem bromelainare prepared differently and they contain different enzymatic composition. "Bromelain" refers usually to the "stem bromelain." Bromelain is a mixture of different thiol endopeptidases and other components like phosphatase, glucosidase, peroxidase...

BACKGROUND Microglial cells act as the sentinel of the central nervous system .They are involved in neuroprotection but are highly implicated in neurodegeneration of the aging brain. When over-activated, microglia release pro-inflammatory factors, such as nitric oxide (NO) and cytokines, which are critical in eliciting neuroinflammatory responses associated with neurodegenerative diseases. This...

Background Bromelain is a collective name for proteolytic enzymes or proteases (natural proteolytic enzymatic complex) found in tissues including stems, fruit and leaves of the pineapple (Ananas comosus var. comosus) and of other plant species of the family Bromeliaceae [1]. Is a bioactive agent possessing remarkable therapeutic properties such as reversible inhibition of platelet aggregation, ...

In the present work an environmentally friendly recycling system to peel away the base coat from the X-ray film by using an enzyme was developed. Bromelain, a proteolytic enzyme extracted from the waste apex of pineapple was used for stripping the silver layer on the exposed film by hydrolysis of gelatin. The collected film can be reused for the manufacturing of X-ray film or other materials li...

PURPOSE We aim to evaluate the efficacy of pollen extract in association with vitamins in patients affected by chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and to evaluate the level of the pro-inflammatory mediators interleukin (IL)-6, IL-8, and IL-10. MATERIALS AND METHODS Patients diagnosed with CP/CPPS between January and December 2015 were enrolled in this study. Participant...

1. The purpose of this study was to evaluate the effects of protein source and enzyme supplementation on protein digestibility and chyme characteristics in broilers. 2. One hundred and twenty growing (13 d old) and 60 finishing (34 d old) Arbor Acre strain commercial male broilers were selected and placed into individual metabolic cages. 3. The experiment was a 5 x 2 factorial arrangement with ...

Methods Stem Br (Vital Nutrients lot # 2890; Middletown, CT), was tested for authenticity and purity. Female C57BL/6J mice, (Jackson Laboratory; Bar Harbor, ME) received one bolus, i.p. injection of Br (12mg/kg) in 0.5ml of physiological saline and plasma collected at baseline 3, 6, 12 and 24 hours. All procedures were approved by the Animal Care Committee at University of CT Health Center. Pos...
