In this work, a multi-core–shell-structured LiFePO4@Na3V2(PO4)3@C (LFP@NVP@C) composite was successfully designed and prepared to address inferior low-temperature performance of LiFePO4 cathode for lithium-ion batteries. Transmission electron microscopy (TEM) confirms the inner NVP outer carbon layers co-existed on surface LFP particle. When evaluated at operation, LFP@NVP@C exhibits an evident...

BACKGROUND Single-dose nevirapine (NVP) is the simplest antiretroviral regimen for the prevention of mother-to-child HIV transmission (PMTCT) in resource-limited settings. We evaluated NVP coverage among HIV-infected delivering women in Côte d'Ivoire. METHODS A cross-sectional survey of mother-infant pairs was conducted between November 2007 and September 2008 in 10 randomly selected faciliti...

OBJECTIVE Nausea and vomiting during pregnancy (NVP) is very common, and may have great impact on a woman's life. The aim of this study was to explore thoughts and attitudes among Norwegian pregnant women and GPs on treatment of NVP and pregnancy care. DESIGN Focus-group study. SETTING AND SUBJECTS Separate focus-group discussions were conducted with pregnant women and GPs. RESULTS Two fo...

background & aim: nausea and vomiting during pregnancy (nvp) is among the most common problems in pregnant women. as explained in guidelines, combination of non-drug treatments, including nutritional modifications, lifestyle changes, and use of alternative medicine for the treatment of nvp has been less highlighted. the present study was performed with the aim of determining the effect of an ed...

Nausea with or without vomiting (NVP) is probably the most frequently reported medical complaint of pregnancy, but few studies have considered risk factors for its development. We used data from an ongoing epidemiological study of pregnancies in four regional centres. Mothers of infants with congenital malformations (n = 17,158) and a sample of normal infants (n = 5,329) were interviewed within...

Nausea and vomiting during pregnancy (NVP) is a condition that affects women around the world. Previous studies show NVP associated with dietary changes aversions towards certain kinds of food. It has been suggested these could have adaptive functions, such as protecting embryo from harmful teratogenic substances in foods. Here, we used food frequency questionnaire to record self-reported consu...

BACKGROUND Single-dose nevirapine (sdNVP)-which prevents mother-to-child transmission of HIV-selects non-nucleoside reverse-transcriptase inhibitor (NNRTI) resistance mutations in the majority of women and HIV-infected infants receiving it. This open-label, randomised trial examined the efficacy of short-course zidovudine (AZT) and lamivudine (3TC) with sdNVP in reducing NNRTI resistance in mot...

PURPOSE This study evaluates the effect of dual PI3K and mTOR inhibition using NVP-BEZ235 in preclinical models of ovarian cancer as a potential novel therapeutic strategy. EXPERIMENTAL DESIGN Inhibition of PI3K/Akt/mTOR signaling by NVP-BEZ235 was demonstrated by immunoblotting. The effect on cell proliferation was assessed in 18 ovarian cancer cell lines, including four pairs of syngeneic c...

BACKGROUND Phosphatidylinositol 3-kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway is a therapy target of cancer. We aimed to confirm the effect of dual PI3K/mTOR inhibitor NVP-BEZ235 on proliferation, apoptosis, and autophagy of chronic myelogenous leukemia (CML) cells and sensitivity of tyrosine kinase inhibitor in vitro. METHODS Two human CML cell lines, K562 and KBM7R (T31...

PURPOSE To examine the effect of hydrogel lens monomer constituents on protein sorption. METHODS A series of hydroxyethylmethacrylate (HEMA)-based hydrogels with various amounts of methacrylic acid (MAA) or N-vinyl pyrrolidone (NVP) were synthesized. A radiolabel tracer technique was used to measure the amount of protein adsorbed on or penetrating into the hydrogels. Penetration of fluorescen...
