Commercial activated carbon (CAC) and biochar are useful adsorbents for removing heavy metals (HM) from water, but their production is costly. Biochar production from olive solid waste from two olive cultivars (Picual and Souri) and two oil production process (two- or three-phase) and two temperatures (350 and 450°C) was tested. The biochar yield was 24-35% of the biomass, with a surface area of 1.65-8.12m(2)g(-1), as compared to 1100m(2)g(-1) for CAC. Picual residue from the two-phase milling technique, pyrolysed at 350°C, had the best cumulative removal capacity for Cu(+2), Pb(+2), Cd(+2), Ni(+2) and Zn(+2) with more than 85% compared to other biochar types and CAC...

Persistent mating-induced endometritis (PMIE) results in decreased fertility in horses, thereby causing a significant impact in the horse market. Platelet-rich plasma (PRP), a modulator of the inflammatory response, has been largely used in veterinary medicine. Here, we investigated the effects of PRP on uterine inflammation, conception rate, endometrial polymorphonuclear neutrophil (PMN) migration, and COX-2 protein levels in the endometrial tissue. Thirteen PMIE-susceptible mares were used for artificial insemination (AI)...

OBJECTIVE: Surgical cytoreduction has been postulated to affect survival by increasing the efficacy of chemotherapy in ovarian cancer. We hypothesized that women with high-grade serous ovarian cancer, which usually responds to chemotherapy, would derive greater benefit from complete cytoreduction than those with histologic subtypes that are less responsive to chemotherapy, such as mucinous and clear cell carcinoma. METHODS: We conducted a retrospective cohort study of patients who underwent primary cytoreductive surgery and adjuvant chemotherapy for stage IIIC or IV epithelial ovarian cancer from 2011 to 2013 using data from the National Cancer Database...

Major depression represents among the most frequent psychiatric disorders in the general population with an estimated lifetime prevalence of 16-17%. It is characterized by high levels of comorbidities with other psychiatric conditions or somatic diseases as well as a recurrent or chronic course in 50 to 80% of the cases leading to negative repercussions on the daily functioning, with an impaired quality of life, and to severe direct/indirect costs. Large cohort studies have supported that failure of a first-line antidepressant treatment is observed in more than 60% of patients...

In this study, bamboo (Phyllostachys pubescens) was successfully deconstructed using an integrated process (autohydrolysis and subsequent delignification). Xylooligosaccharides, high-purity lignin, and digestible substrates for producing glucose can be consecutively collected during the integrated process. The structural change and fate of lignin during autohydrolysis process was deeply investigated. Additionally, the structural characteristics and active functional groups of the lignin fractions obtained by these delignification processes were thoroughly investigated by NMR (2D-HSQC and (31)P NMR) and GPC techniques...

Creatine (Cr), phosphocreatine (PCr), and creatine kinases (CK) comprise an energy shuttle linking ATP production in mitochondria with cellular consumption sites. Myocytes cannot synthesize Cr: these cells depend on uptake across the cell membrane by a specialized creatine transporter (CrT) to maintain intracellular Cr levels. Hypoxia interferes with energy metabolism, including the activity of the creatine energy shuttle, and therefore affects intracellular ATP and PCr levels. Here, we report that exposing cultured cardiomyocytes to low oxygen levels rapidly diminishes Cr transport by decreasing Vmax and Km Pharmacological activation of AMP-activated kinase (AMPK) abrogated the reduction in Cr transport caused by hypoxia...

Non-alcoholic fatty liver disease is the most commonly occurring chronic liver disease, and hepatic steatosis, a condition defined as extensive lipid accumulation in hepatocytes, is associated with liver dysfunction and metabolic diseases, such as, obesity and type II diabetes. Apelin is an adipokine that acts on a G protein-coupled receptor named APJ, and has been established to play pivotal roles in various physiological conditions. However, the function of apelin in hepatocytes has not been fully investigated...

The complexities, interdependencies, and ambiguity that face next generation emergency management meta-leaders in an ever-evolving global community heighten the expectation and need for competencies that far exceed those common in practice today and necessitate the ability to move seamlessly through the dimensions of meta-leadership (ie, the person, the situation, and connectivity) while utilizing scientific-based evidence, information, resources, processes, and tools. The objective of this effort was to examine the recently developed next generation emergency management competencies through a meta-leadership lens by juxtaposing the competencies and the meta-leadership model...

Ethyl carbamate (EC) is a food and environmental toxicant and is a cause of concern for human exposure. Several studies indicated that EC-induced toxicity was associated with oxidative stress. Mulberry fruits are reported to have a wide range of bioactive compounds and pharmacological activities. The present study was therefore aimed to investigate the protective property of mulberry fruit extract (MFE) on EC-induced cytotoxicity and oxidative stress. Chemical composition analysis showed that total phenolic content and total flavonoid content in MFE were 502...

While polycrystalline lead oxide (poly-PbO) is known to be one of the most promising photoconductors for utilization in X-ray detectors, its major performance parameters such as charge yield and mobility-lifetime product (μτ) are still not well established and require further investigation. Combining the conventional X-ray induced photocurrent and pulse height spectroscopy techniques we examine the X-ray photogeneration and recombination processes in poly-PbO. The measurements indicate that the amount of energy required to release a single electron hole pair W ± (inverse of charge yield) strongly depends on applied electric field and at 10 V/μm reaches ~20 eV/ehp...

Adults with acute lymphoblastic leukemia (ALL) do worse than children. From 7/2008 to 12/2014, Nordic and Baltic centers treated 1509 consecutive patients 1-45 years with Philadelphia chromosome-negative ALL according to the NOPHO ALL2008 without cranial irradiation. 1022 patients were 1-9 years (A), 266 were 10-17 years (B), and 221 were 18-45 years (C). Sixteen patients (three adults) died during induction. All others achieved remission after induction or 1-3 intensive blocks. Subsequently, 45 patients (12 adults) died, 122 patients relapsed (32 adults) with a median time to relapse of 1...

Allogeneic hematopoietic cell transplant advances for sickle cell disease improve outcomes, but limited healthcare utilization analysis exists. We hypothesized that early transplant (age < 10 years) improves outcomes and decreases healthcare utilization compared to late. We performed a retrospective study of US children transplanted for sickle cell during 2000-2013 using two large databases. Univariate and Cox models estimated associations between demographics, sickle cell severity, and transplant-related variables on mortality and chronic graft versus-host-disease; while, Wilcoxon, Kruskal-Wallis, or linear trend tests estimated against healthcare utilization...

This study aimed to improve the biomethane potential of dairy waste activated sludge (WAS) by H2O2-acidic pH induced microwave disintegration (HAMW-D) pretreatment approach. The results of HAMW-D compared with the microwave disintegration (MW-D) alone for energy and economic factors. In the two phase disintegration process, the H2O2 concentration of about 0.5mg/g SS under acid pH of 5 was found to be optimum for effective dissociation of Extracellular Polymeric Substances (EPS) matrix. A higher liquefaction of about 46...

INTRODUCTION: Preterm neonates are particularly at risk of vitamin D (25-D) deficiency. To prevent rickets and osteopenia in this population, international guidelines vary between 800 and 1000IU per day of vitamin D in Europe and recommend 400IU per day in the USA. Target levels of circulating 25-D are not well identified, with the lower target level 50-75nmol/L and the upper target level probably 120nmol/L. METHODS: Between 2013 and 2015, 16 premature infants (born<35WG) were referred to pediatric nephrology clinics because of symptoms secondary to 25-D overdose during the neonatal period...

There has been a sustained effort in recent years to develop products with the potential to present less risk compared with continued smoking as an alternative for adult smokers who would otherwise continue to smoke cigarettes. During the non-clinical assessment phase of such products, the chemical composition and toxicity of their aerosols are frequently compared to the chemical composition and toxicity of the smoke from a standard research cigarette - the 3R4F reference cigarette. In the present study, it is demonstrated that results of these analytical comparisons are similar when considering commercially available cigarette products worldwide...

While a good number of studies have demonstrated that modern, man-made ambient electromagnetic fields can have both stimulatory and inhibitory effect on immune system function, the precise mechanisms have yet to be completely elucidated. It is hypothesized here that, depending on the parameters, one of the means by which long-term electromagnetic field exposure has the potential to eventually lead to immunosuppression is via downstream inhibition of the enzyme calcineurin - a protein phosphatase, which activates the T-cells of the immune system and can be blocked by pharmaceutical agents...

Health literacy, the degree to which individuals have the capacity to obtain, process, and understand health information and services needed to make health decisions, is an essential element for early adults (aged 18-44 years) to make informed decisions about cancer. Low health literacy is one of the social determinants of health associated with cancer-related disparities. Over the past several years, a nonprofit organization, a university, and a cancer center in a major urban environment have developed and implemented health literacy programs within healthcare systems and in the community...
