Firozeh Saberzadeh Sarvestani, Hossein Esmaeili, Bahman Ramavandi
In this paper, a new and facile approach for molybdate loading in the brown algae of Sargassum angustifolium is introduced. The molybdate ions were entered into the algae body during a short cultivation to produce algae-Mo as a novel adsorbent for eliminating phosphate ions from synthetic and real wastewaters. Results of the surface analysis showed that molybdate loading onto the algae was successfully performed. Herein, basic variables, such as initial solution pH, adsorbent dosage, contact time, phosphate concentration, and temperature, were investigated in detail to assess the phosphate adsorption performance of algae-Mo...

Xylitol production was compared in fed batch fermentation by Saccharomyces cerevisiae strains overexpressing xylose reductase (XR) genes from Candida tropicalis, Pichia stipitis, Neurospora crassa, and an endogenous gene GRE3. The gene encoding a xylose specific transporter (SUT1) from P. stipitis was cloned to improve xylose transport and fed batch fermentation was used with glucose as a cosubstrate to regenerate NADPH. Xylitol yield was near theoretical for all the strains in fed batch fermentation. The highest volumetric (0...

Aconitum heterophyllum is an important component for various herbal drug formulations due to the occurrence of non-toxic aconites including marker compound, atisine. Despite huge pharmacological potential, the reprogramming of aconites production is limited due to lack of understanding on their biosynthesis. To address this problem, we have proposed here the complete atisine biosynthetic pathway for the first time connecting glycolysis, MVA/MEP, serine biosynthesis and diterpene biosynthetic pathways. The transcript profiling revealed phosphorylated pathway as a major contributor towards serine production in addition to repertoire of genes in glycolysis (G6PI, PFK, ALD and ENO), serine biosynthesis (PGDH and PSAT) and diterpene biosynthesis (KO and KH) sharing a similar pattern of expression (2-4-folds) in roots compared to shoots vis-à-vis atisine content (0-0...

Fipronil is a widely used insecticide in agriculture and can cause potential health hazards to non-target soil invertebrates and nearby aquatic systems. In the present study, a fipronil degrading bacterium was isolated from fipronil contaminated soil, i.e. rhizospheric zone of Zea mays. Morphological, biochemical and molecular characterization of strain indicated that it clearly belongs to Stenotrophomonas acidaminiphila (accession no. KJ396942). A three-factor Box-Behnken experimental design combined with response surface modeling was employed to predict the optimum conditions for fipronil degradation...

BACKGROUND AND PURPOSE: Proximal large vessel occlusion (LVO) is present in up to 30% of minor strokes. There is no proven effectiveness of MT in the subgroup of minor stroke with LVO in the anterior circulation and data about mechanical thrombectomy (MT) in this subgroup of patients are sparse, with optimal management of these patients being yet not definitely addressed. The purpose of this case-control study was to evaluate MT in patients suffering from acute ischemic stroke (AIS) and LVO in the anterior circulation, presenting with minor to mild stroke symptoms (NIHSS<8)...

Background Hypercholesterolemia plays a causal role in the development of cardiovascular diseases. Patients are affected differently. There is a lack of epidemiological data about the frequence and characteristics of patients in Germany, especially about those who do not respond sufficiently to high intensity statins with or without other lipid modifying therapies. Methods From more than 2.6 million patient records of office based general practitioners, patients with hypercholestrolemia and high cardiovascular risk, who do not reach their individual LDL-C goal despite a best supplied twelve month maximum lipid lowering therapy (MPR ≥ 80 %), were extracted from the database...

Doxorubicin (DOX), one of the most commonly used anticancer medications, has been reported to affect fertility by damaging ovarian follicles; however, the dose-dependent toxicity of DOX on the dynamic follicle development and oocyte maturation has not been well-defined. Our objective is to determine the effects of human-relevant exposure levels of DOX on follicular functions across developmental time. In vitro cultured multilayered secondary mouse follicles were treated with DOX at 0, 2, 20, 100, and 200 nM for 24 hours, and follicle development, hormone secretion, and oocyte maturation were analyzed...

Similar to organophosphate (OP) nerve agents, diisopropylfluorophosphate (DFP) rapidly and irreversibly inhibits acetylcholinesterase, leading to convulsions that can progress to status epilepticus (SE). However, in contrast to the OP nerve agents, the long-term consequences of DFP-induced SE are not well known. Thus, we characterized the spatiotemporal profile of neuropathology during the first two months following acute DFP intoxication. Adult, male Sprague Dawley rats administered pyridostigmine bromide (0...

Environmental chemicals termed "obesogens" disrupt the endocrine system to promote adipogenesis and obesity. Tetrabromobisphenol-A (TBBPA) has been reported to increase adipogenesis, however, the mechanism(s) of action are unclear. Thy1 (CD90) is a glycophosphatidylinositol (GPI) -anchored membrane protein that serves as a marker for stem cells and also plays an important role in regulating adipogenesis and obesity. We investigated whether or not TBBPA promotes adipogenesis in human and mouse cells by reducing Thy1 levels...

BACKGROUND: College students perceive widespread availability of drugs and prescription medications for non-medical use on campus, but less is known about the relationship between opportunity to use, use, and use given opportunity of these drugs during and after college. The current study describes annual trends in (1) opportunity to use, (2) use, and (3) use given opportunity of eight drugs and three prescription medications used non-medically over seven years. METHODS: Data were derived from a longitudinal cohort study of 1253 first-year college students (52% female, 72% non-Hispanic white) at one large, public university...

A third of basal cell carcinoma (BCC) patients will develop metachronous BCCs, but information is limited on the frequency, timing and predictors of these subsequent BCCs. We aimed to develop a prediction model to assess the absolute risk of metachronous BCCs.We observed 14,628 participants of northwestern European ancestry from a prospective population- based cohort study (Rotterdam Study). BCCs were identified using a linkage with the Dutch Pathology Registry (PALGA). Predictors for subsequent BCCs included 14 patient, lifestyle, and tumor-specific characteristics...

Tobacco smoking is a strong risk factor for cancer, but associations with basal cell carcinomas (BCC) and squamous cell carcinomas (SCC) of the skin have been inconsistent. We prospectively investigated the associations between cigarette smoking and 3-year incidence of first primary BCC or SCC in the QSkin cohort (n=43765). Smoking history was self-reported at baseline; newly diagnosed and surgically treated BCCs and SCCs were ascertained through linkage to the national health insurance scheme and verified by histopathology reports...

Actinic keratoses (AK) are common, costly, and may evolve to keratinocyte carcinoma (KC): basal cell (BCC) and squamous cell carcinoma (SCC) of the skin. Time to malignant transformation is controversial. We used data from the placebo arm (n=166) of a randomized trial of veterans with multiple prior KCs. Study dermatologists examined participants' faces/ears at enrollment and semiannual visits. Clinically diagnosed AKs were marked, photographed, and treated with cryotherapy (starting at 6 months). Lesions suspicious for KC were marked, photographed, and biopsied...
