– We derive excess carrier populations in quantum wells, embedded in the intrinsic region of p-i-n solar cells. In the process of the analysis, we (a) solve for photo-generated carriers in quantum wells and (b) determine explicit dependence on incident solar wavelength. We include in the computations the existence of optical gaps near 1eV or wavelengths in the near infrared, so that our complet...

OBJECTIVES In multiple myeloma, heparanase (HSPE) is involved in myeloma cell growth, angiogenesis, osteoclastogenesis and shedding of syndecan-1, a key player in myeloma pathophysiology. Different single nucleotide polymorphisms (SNPs) in the HSPE gene with effect on gene function have been described, and some are associated with haematological malignancies. METHODS In this study, we evaluat...

PURPOSE The purpose of this study is to investigate the role of fibroblast growth factor receptor 4 (FGFR4) polymorphism in esophageal cancer after chemoradiotherapy (CRT). MATERIALS AND METHODS Peripheral blood samples from 244 patients treated with CRT for esophageal squamous cell carcinoma were assessed for the role of FGFR4 genotype on treatment response and survival. RESULTS A total of...

Brain-derived neurotrophic factor (BDNF) is a neurotrophin which has been shown to regulate cell survival and proliferation, as well as synaptic growth and hippocampal long-term potentiation. A naturally occurring single nucleotide polymorphism in the human BDNF gene (val66met) has been associated with altered intercellular trafficking and regulated secretion of BDNF in met compared to val carr...

Background Apolipoprotein E4 (APOE4) has toxic effects on the cerebrovascular system, neuronal function, and functional connectivity of brain networks (e.g., default-mode, frontal-attention, salience networks). The thalamus, a vital structure that acts as relay station between many networks, become interest in AD research with studies showing atrophy among those early diminished cortical-thalam...

iran is one of the most energy-rich countries subsidizing energy carriers, especially in the agricultural sector, to the extent that the resulting growth is at the expense of the environment. this study tries to investigate the potential impacts of energy price reform on the agro-environment, based on the marginal abatement costs (macs) of emissions. firstly, the energy demand function of the a...

Significant relations were observed between select infant-care and weaning behaviors and growth in body weight in common marmoset monkeys (Callithrix jacchus). The patterns of these relations suggest that earlier occurrence of developmental milestones, such as cessation of transport (being off carriers) and weaning to solid food, were associated with slower growth during the subsequent period. ...

Background: The incidence of esophageal squamous cell carcinoma (ESCC) is increasing, causing catastrophic health burdens on communities. Curcumin has shown promise as a therapeutic agent in the treatment of colon, colorectal, pancreatic, and esophageal cancers but it has very poor bioavailability. The application of nano-carriers as drug delivery systems increases curcumin's bioavailability. C...
