The past few years have been great for semiconductor quantum dot-sensitized solar cells (QDSSCs). For the first time, efficiency exceeding 15% has reported. This narrowed gap with other emerging cell technologies such as dye-sensitized and thin film cells. In this miniperspective, reason improvement is briefly reviewed. Few advancements identified that are responsible performance breakthrough i...
The clinical importance of preexisting HLA antibodies at the time of transplantation, identified by contemporary techniques, is not well understood. We conducted an observational study analyzing the association between preexisting donor-specific HLA antibodies (HLA-DSA) and incidence of acute antibody-mediated rejection (AMR) and survival of patients and grafts among 402 consecutive deceased-do...
Endocarditis is a rare but serious manifestation of Listeria monocytogenes (LM). However, the optimal treatment strategy for LM endocarditis has yet to be established. Current antibiotic strategies for listeriosis include penicillin G or ampicillin (AMP) monotherapy, or AMP + gentamicin combination therapy which is often favored for endocarditis. The primary objective of our investigation was t...
Interactions between poly-dispersed acid functionalized single walled carbon nanotubes (AF-SWCNTs) and primary lung epithelial (PLE) cells were studied. Peritoneal macrophages (PMs, known phagocytic cells) were used as positive controls in this study. Recovery of live cells from cultures of PLE cells and PMs was significantly reduced in the presence of AF-SWCNTs, in a time and dose dependent ma...
We extend the technique of fluorescence resonance energy transfer (FRET) by introducing a luminescent terbium chelate as a donor and an organic dye, tetramethylrhodamine, as an acceptor. The results are consistent with a Förster theory of energy transfer, provided the appropriate parameters are used. The use of lanthanide donors, in general, and this pair, in particular, has many advantages ove...
The dyes extracted from pomegranate and berry fruits were successfully used in the fabrication of natural dye sensitized solar cells (NDSSC). The morphology, porosity, surface roughness, thickness, absorption and emission characteristics of the pomegranate dye sensitized photo-anode were studied using various analytical techniques including FESEM, EDS, TEM, AFM, FTIR, Raman, Fluorescence and Ab...
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising candidate for cancer treatment, but some cancer cell types are resistant to TRAIL cytotoxicity. Therefore, overcoming this resistance is necessary for effective TRAIL therapy. Mitochondrial morphology is important for the maintenance of cell function and survival, and is regulated by the delicate balance between fiss...
ارزیابی تاثیر باکتری محرک رشد (pseudomonas fluorescence) و کود آلی (ورمی کمپوست و کمپوست تفاله شیرین بیان) بر ویژگی-های مورفوفیزیولوژیک گیاه به لیمو و بررسی امکان کاربرد آن به عنوان یک گیاه زینتی انجام شد.صفات مورد بررسی شامل صفات مورفولوژیک، کلروفیل کل، کلروفیل a و b، کارتنوئید کل، میزان و عملکرد اسانس، فعالیت آنتی اکسیدانی و میزان غلظت عناصر n، p و k موجود در گیاه بود.
BACKGROUND Late asthmatic response is observed following antigen challenge in actively, but not passively, sensitized guinea pigs. Although cough reflex sensitivity is increased after antigen challenge in actively sensitized guinea pigs, it is unknown whether the antigen-induced increase in cough reflex sensitivity develops in passively sensitized animals. The aim of this study was to compare t...
background: cuminum cyminum fruit essential oil (feo) dose-dependently can attenuate the expression of morphine tolerance and dependence in morphine-dependent mice. objective: in this study, the effects of cuminum cyminum feo on acquisition and expression of morphine-induced conditioned place preference (cpp) in morphine-sensitized mice were studied. methods: repeated subcutaneous (s.c.) admini...
