The aim of the present work was to develop a simple and rapid method for determination of theophylline (THP) and guaifenesin (GU) in syrup without involving any preparation operations like separation or masking. A HPLC and two spectrophotometric methods based on the derivation of the main spectra are described for the determination of THP and GU in combined pharmaceutical syrup form. The first ...

background: discovery of short cell free fetal dna (cffdna) fragments in maternal plasma has created major changes in the field of prenatal diagnosis. the use of cffdna to set up noninvasive prenatal test is limited due to the low concentration of fetal dna in maternal plasma therefore, employing a high efficiency extraction method leads to more accurate results. the aim of this study was to ev...

Flavonoids have been shown to be effective in protecting against age-related cognitive and motor decline in both in vitro and in vivo models. Recently, a flavonoid-rich extract of Citrus bergamia juice (BJe) has been shown to display anti-oxidant and anti-inflammatory properties against LPS-induced activation of human THP-1 monocytes. In the light of these observations, we wondered whether BJe ...

PDLIM2 (Mystique/SLIM) is a postsynaptic density-95/discs large/zonula occludens-1-Lin-11, Isl-1, Mec-3 (PDZ-LIM) domain protein expressed in the nucleus of T lymphocytes, where it promotes degradation of the p65 subunit of NF-kappaB. It is also expressed at the cytoskeleton in epithelial cells, where it is essential for cell migration. It is not known whether PDLIM2 function at the nucleus and...

OBJECTIVE The objective of this study was to determine the effects and potential mechanisms of C-reactive protein (CRP) on cholesterol efflux from human macrophage foam cells, which may play a critical role in atherogenesis. METHODS AND RESULTS Human THP-1 monocytes and peripheral blood mononuclear cells (PBMCs) were preincubated with acetylated LDL and [3H]-cholesterol to form foam cells, wh...

The ubiquitin-proteasome pathway is the principal mechanism for the degradation of short-lived proteins in eukaryotic cells. We demonstrated that treatment of THP-1 human monocytic leukemia cells with Z-LLL-CHO, a reversible proteasome inhibitor, induced cell death through an apoptotic pathway. Apoptosis in THP-1 cells induced by Z-LLL-CHO involved a cytochrome c-dependent pathway, which includ...

Accumulating evidence suggest a reciprocal interaction between neurosteroids, especially 5alpha-pregnan-3alpha-ol,20-one (3alpha,5alpha-THP, allopregnanolone), and the serotonergic (5-HT) system. Both 5-HT and neurosteroids seem to play an important role in the pathophysiology of major depression. We have previously shown that a 7-d treatment with 3alpha,5alpha-THP drastically increases the spo...

Objective We retrospectively compared the clinical efficacy and toxicity of rituximab (R)-THP-COP (pirarubicin, cyclophosphamide, vincristine, and prednisolone) with that of R-CHOP (rituximab, adriamicin, cyclophosphamide, vincristine, and prednisolone) in previously untreated old patients with diffuse large B-cell lymphoma (DLBCL). Patients and Methods Patients admitted to our institution betw...
