BACKGROUND: It is reported that women in developing countries reach menopause earlier compared to developed countries. This seems to be due to underestimation of age at menopause as pre-menopause women who will reach menopause at older ages are commonly excluded in cross-sectional settings. In this study, we propose an estimation method which can deal with this bias. We also assessed major determinants of menopause. METHODS: The second national integrated micronutrient survey in Iran completed in 2015 is a population-based study with a nationally representative sample of 4,898 Iranian women aged 50 to 60 years...

BACKGROUND: Health-related quality of life (HRQOL) is associated with household food insecurity (HFI). However, the studies examining the relationship between HFI and HRQOL in patients with type 2 diabetes are scarce. Thus, this study was designed to examine the relationship between HFI and HRQOL in rural type 2 diabetic patients. METHODS: In this cross-sectional study, we included 1847 rural patients with type 2 diabetes in Neyshabur from April to July 2012. HRQOL and HFI were measured with 36-item HRQOL (SF-36) and 6-item version of Household Food Security questionnaires, respectively...

Epithelial ovarian cancer (EOC) is the most lethal gynaecological malignancy worldwide. Development of chemoresistance and peritoneal dissemination of EOC cells are the major reasons for low survival rate. Targeting signal transduction pathways which promote therapy resistance and metastatic dissemination is the key to successful treatment. Members of the ErbB family of receptors are over-expressed in EOC and play key roles in chemoresistance and invasiveness. Despite this, single-targeted ErbB inhibitors have demonstrated limited activity in chemoresistant EOC...

Neuronal network oscillations represent a main feature of the brain activity recorded in the EEG under normal and pathological conditions such as epilepsy. Specific oscillations occur between seizures in patients and in animal models of focal epilepsy, and thus they are termed interictal. According to their shape and intrinsic signal frequency, interictal oscillations are classified as spikes and high frequency oscillations (HFOs). Interictal spikes are recorded in the "wideband" EEG signal and consist of large-amplitude events that usually last less than 1 s; HFOs, in contrast, are extracted by amplifying the appropriately filtered EEG signal, and are usually categorized as ripples (80-200 Hz) and fast ripples (250-500 Hz)...

PURPOSE OF REVIEW: In this review we discuss how environmental exposures predominate the etiology of colorectal cancer (CRC). With CRC being a personalized disease influenced by genes and environment, our goal was to explore the role metabolomics can play in identifying exposures, assessing the interplay between co-exposures, and the development of personalized therapeutic interventions. RECENT FINDINGS: Approximately 10 % of CRC cases can be explained by germ-line mutations, whereas the prevailing majority are caused by an initiating exposure event occurring decades prior to diagnosis...

Immune control is associated with nigrostriatal neuroprotection for Parkinson's disease (PD); though its direct cause and effect relationships have not yet been realized and modulating the immune system for therapeutic gain has been openly discussed. While the pathobiology of PD remains in study, neuroinflammation is thought to speed nigrostriatal degeneration. The neuroinflammatory cascade associated with PD begins with aggregation of misfolded or post-translationally modified α-synuclein (α-syn). Such aggregation results in neuronal cell death and the presence of chronically activated glia (microglia and astroglia), leading to the production of proinflammatory cytokines like tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), IL-6, and enzymes such as nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and cyclooxygenase-2 (COX-2)...

Dual-targeted drug delivery system has established their reputation as potent vehicles for cancer chemotherapies. Herein, gemcitabine (Gem) was conjugated to human serum albumin (HSA) via dithiodipropionic anhydride (DTDPA) to fabricate Gem-HSA nanoparticles. It was hypothesized that this system can enhance the low stability of Gem and can improve its intracellular delivery. Furthermore, folate was applied as targeting agent on HSA nanoparticles for increasing the tumor selectivity of Gem. In order to evaluate the structural properties of synthesized products, (1) H NMR and FT-IR were performed...

Optical coherence tomography (OCT) delivers 3-dimensional images of tissue microstructures. Although OCT imaging offers a promising high-resolution method, OCT images experience some artifacts that lead to misapprehension of tissue structures. Speckle, intensity decay, and blurring are 3 major artifacts in OCT images. Speckle is due to the low coherent light source used in the configuration of OCT. Intensity decay is a deterioration of light with respect to depth, and blurring is the consequence of deficiencies of optical components...

Glioblastoma multiforme (GBM) is the most common primary malignant brain tumor and accounts for a significant proportion of all primary brain tumors. Median survival after treatment is around 15 months. Remodeling of N-glycans by the N-acetylglucosamine glycosyltransferase (MGAT5) regulates tumoral development. Here, perturbation of MGAT5 enzymatic activity by the small-molecule inhibitor 3-Hydroxy-4,5-bis-benzyloxy-6-benzyloxymethyl-2-phenyl2-oxo-2λ5-[1,2]oxaphosphinane (PST3.1a) restrains GBM growth. In cell based assays it is demonstrated that PST3...

In Persian nutrition culture, drinking aromatic waters (hydrosols, distillate) has a long history as functional beverages or therapeutic remedies. The co-distilled water with essential oils, which contains partial amounts of more water-soluble volatile compounds are diluted and used as beverages. Since the solubility of volatile components is different in water, the overall composition, and thus the biological activities of aromatic waters seem to be different from the essential oils they were co-distilled with...

Dissolution dynamic nuclear polarization (DNP) is one of the most successful techniques that resolves the insensitivity problem in liquid-state nuclear magnetic resonance (NMR) spectroscopy and imaging (MRI) by amplifying the signal by several thousand-fold. One way to further improve the DNP signal is the inclusion of trace amounts of lanthanides in DNP samples doped with trityl OX063 free radical as the polarizing agent. In practice, stable monomeric gadolinium complexes such as Gd-DOTA or Gd-HP-DO3A are used as beneficial additives in DNP samples, further boosting the DNP-enhanced solid-state 13C polarization by a factor of 2 or 3...
