Since little is known about Tc cells in the human immune response to intracellular parasites, we have studied the role of Tc cells in response to M. bovis Bacillus Calmette-Guerin (BCG). Donors whose PBMC responded to BCG, purified protein derivative (PPD), and the recombinant 65-kD heat shock protein (HSP) of BCG generated BCG/PPD-specific CD4+ effector T lymphocytes that lysed PPD as well as ...

Enzymatic removal of the methoxycarbonyl group of pheophorbide (Pheid) a in chlorophyll degradation was investigated in cotyledons of radish (Raphanus sativus). The enzyme pheophorbidase (PPD) catalyzes the conversion of Pheid a to a precursor of pyropheophorbide (PyroPheid), C-13(2)-carboxylPyroPheid a, by demethylation, and then the precursor is decarboxylated nonenzymatically to yield PyroPh...

BACKGROUND Up to 20% of women experience postpartum depression (PPD). PPD is associated with anxiety and poor health-related quality of life (HRQOL). Efficacious treatments are critical; many women with PPD prefer complementary therapies. Thus, the current study examined yoga as a complementary therapy for PPD. METHODS Fifty-seven postpartum women with scores ≥12 on the Hamilton Depression Ra...

Para-phenylene diamine ( PPD ) systemic intoxication in Saudi Arabia has been increased over the last decade. The aim of the this study was to provide more insight into PPD intoxication with reviewing possible underlying mechanisms. The topical treatment with PPD (2mg/kg) for 5 weeks and its subsequent withdrawal caused decreased in monoamines (noerepinephrine, dopamine, serotonin and histamine...

In a previous report, we demonstrated that ginsenoside Rc, one of major ginsenosides from Panax ginseng, enhances γ-aminobutyric acid (GABA) receptorA (GABAA)-mediated ion channel currents. However, little is known about the effects of ginsenoside metabolites on GABAA receptor channel activity. The present study investigated the effects of ginsenoside metabolites on human recombinant GABAA rece...

The core element of the PROFES improvement methodology is the concept of product-process dependency (PPD) models. The purpose of PPD models is to help focus process improvement activities to those development technologies and processes that are most effective with regards to achieving specific customer-defined product quality goals. This paper describes how system dynamics simulation models can...

ing from these five main categories, we found that “mothering is overwhelming” is the core experience of PPD symptoms for low-income women. The demands of parenting small children, along with mothers’ ambivalence, isolation, juggling, and real-life worries, converged to produce an understanding of PPD as feeling overwhelmed by both the material and emotional demands of mothering in the context ...

We examined the effectiveness and efficiency of 2 instructional arrangements using progressive prompt delay (PPD) with 3 young children with autism and 1 child with developmental delays. Specifically, we compared PPD with instructive feedback (IF) to PPD without IF in an adapted alternating treatment design. The results suggested that (a) children with autism and developmental delays can learn ...

The tuberculin skin test (TST) using purified protein derivative (PPD) of Mycobacterium tuberculosis is traditionally used to diagnose latent tuberculosis (TB) infection (LTBI). However, LTBI diagnosis by peripheral blood mononuclear cell (PBMC) interferon (IFN)-gamma responses to M. tuberculosis-specific antigens, early secreted antigenic target 6 kDa (ESAT-6) and culture filtrate protein (CFP...
