Herein, we detail how to grow one crystalline organic semiconductor on another epitaxially and thereby provide a method to tune the electronic nature of the p–n junction in organic photovoltaics (OPVs). While OPVs are attractive as materials for conversion of sunlight into electrical energy, higher conversion efficiencies are needed for OPVs to become a viable technology. Regardless of the type...

Objective: Fuzheng Huayu (FZHY) capsules exert anti-liver fibrosis and cirrhosis effects. This study aimed to determine the effect of FZHY on 6-month survival rate patients with overt hepatic encephalopathy (OHE) hepatitis B-related (HBC). Methods: A total 517 OHE HBC treated between January 2008 July 2018 were enrolled. Patients divided into (n = 129) control groups 388), rates compared two gr...

BACKGROUND Data regarding Hepatitis B and C viruses (HBV and HCV) prevalence among military personnel in Brazil are lacking, but the work-related risk of exposure can be high. The objective of this study was to estimate the seroprevalence of HBV and HCV and the risk factors associated to HBV exposure among Brazilian military personnel. METHODS A cross-sectional study was conducted and include...

BACKGROUND Haemoglobin S (HbS) and C (HbC) are variants of the HBB gene which both protect against malaria. It is not clear, however, how these two alleles have evolved in the West African countries where they co-exist at high frequencies. Here we use haplotypic signatures of selection to investigate the evolutionary history of the malaria-protective alleles HbS and HbC in the Kassena-Nankana D...

Hepatitis B Virus core (HBc) particles have been studied for their potential as drug delivery vehicles for cancer therapy. HBc particles are hollow nano-particles of 30-34 nm diameter and 7 nm thick envelopes, consisting of 180-240 units of 21 kDa core monomers. They have the capacity to assemble/dis-assemble in a controlled manner allowing encapsulation of various drugs and other biomolecules....

OBJECTIVES Hepatitis B virus (HBV) infection is an important worldwide public health problem and it has been cause of elevated morbidity and mortality rates. The objectives of this study were determine the HBV infection seroprevalence in psychiatric institutions and in individuals with Down's syndrome, detect viral DNA in HBsAg and anti-HBc total positive serum samples and determine the HBsAg s...

BACKGROUND Hepatitis D Virus (HDV) causes accelerated liver diseases in patients with Hepatitis B Virus (HBV) infection. There is lack of data about its prevalence, related risk factors and interaction with HBV carriers in our country. OBJECTIVES The aim of this study was to estimate the prevalence of hepatitis delta and associated risk factors among Hepatitis B surface antigen (HBsAg) and "i...

With a view to combining the desirable electronic and photochemical properties of hexabenzocoronene (HBC) and the C-C bond forming capabilities of thiophenes, 1-(3-thienyl)-2,3,4,5,6-penta(4-tert-butyl-phenyl)benzene (1) was oxidised using FeCl(3). The resulting products, superaromatic thiophene (2) and its 5,5'-dimer (3), are S-HBC systems and provide a new pair of spectral comparators.

Signal transduction via modulation of phosphorylation after selective inhibition of protein phosphatase (PP) 1 and/or PP2A appears to play a role in okadaic acid (OA)-mediated effects. Treatment of several estrogen receptor-negative human breast carcinoma (HBC) cells with 100 nM OA resulted in induction of c-fos, c-myc, and cyclin-dependent kinase inhibitor p21WAF1/CIP1 genes. Transfections of ...
