The effect of cell disruption on the extraction of oil and protein from concentrated microalgae slurries.

Novel cell-disruption combinations (autolytic incubation and hypotonic osmotic shock combined with HPH or pH12) were used to investigate the fundamental mass transfer of lipids and proteins from Nannochloropsis slurries (140 mg biomass/g slurry). Since neutral lipids exist as cytosolic globules, their mass transfer was directly dependent on disintegration of cell walls. Complete recovery was obtained with complete physical disruption.

Analysis of the lipid extraction performance in a cascade process for Scenedesmus almeriensis biorefinery.

Background: Microalgae have attracted considerable interest due to their ability to produce a wide range of valuable compounds. Pulsed Electric Fields (PEF) has been demonstrated to effectively disrupt the microalgae cells and facilitate intracellular extraction. To increase the commercial viability of microalgae, the entire biomass should be exploited with different products extracted and valorized according to the biorefinery scheme.

Pulsed Electric Field Treatment Promotes Lipid Extraction on Fresh Oleaginous Yeast DSM 27192.

This study reports on the use of pulsed electric field (PEF) as a pre-treatment step to enhance lipid extraction yield using extraction with ethanol-hexane blend on fresh oleaginous yeast The yeasts were cultivated on nitrogen-depleted condition and had a lipid content of 26.4 ± 4.6% of dry weight.

Exploring perceptions, attitudes and beliefs of Thai patients with type 2 diabetes mellitus as they relate to medication adherence at an out-patient primary care clinic in Chiang Mai, Thailand.

Background: Within the sphere of diabetes self-management, much emphasis has been placed on medication adherence. There has been a shift in thinking about medication adherence, moving from "compliance" and historically paternalistic models of care, to seeking better ways of characterizing dynamic and complex relationships that determine medication adherence and diabetes control. This study sought to understand the relationship between patient's attitudes and medication adherence for oral anti-diabetics in Thailand.

Evaluation of Downstream Processing, Extraction, and Quantification Strategies for Single Cell Oil Produced by the Oleaginous Yeasts DSM 27192 and DSM 27194.

Single cell oil (SCO) produced by oleaginous yeasts is considered as a sustainable source for biodiesel and oleochemicals since its production does not compete with food or feed and high yields can be obtained from a wide variety of carbon sources, e.g., acetate or lignocellulose.

Effect of early palliative care for patients with glioblastoma (EPCOG): a randomised phase III clinical trial protocol.

​INTRODUCTION: Randomised controlled trials (RCTs) have shown a positive effect of early integration of palliative care (EIPC) in various advanced cancer entities regarding patients' quality of life (QoL), survival, mood, caregiver burden and reduction of aggressiveness of treatment near the end of life. However, RCTs investigating the positive effect of EIPC for patients suffering from glioblastoma multiforme (GBM) are lacking. After modelling work identifying the specific needs of GBM patients and their caregivers, the aim of this study is to investigate the impact of EIPC in this particular patient group.

Improving the prevention and diagnosis of melanoma on a national scale: A comparative study of performance in the United Kingdom and Australia.

We undertook this study in light of an uncontrolled rise of melanoma incidence and mortality rates in the United Kingdom (UK). We aim to assess the effectiveness of prevention and early melanoma diagnosis in the UK's National Health Service (NHS) in comparison to the Australian system that has limited the melanoma rise. We compare the prevention campaigns against skin cancer and the stage at which melanoma is diagnosed.

Incubation time after pulsed electric field treatment of microalgae enhances the efficiency of extraction processes and enables the reduction of specific treatment energy.

Pulsed Electric Field (PEF) pre-treatment, applied on fresh microalgae Auxenochlorella protothecoides, induces spontaneous release of a substantial water fraction and enables subsequent lipid extraction using ethanol-hexane blends. In this study, fresh microalgae suspensions were treated with PEF and incubated under inert conditions. Incubation promotes the release of ions and carbohydrates and increases the yields of subsequent lipid extraction thus enabling a considerable reduction of PEF-treatment energy.

Patient experience of centralized acute stroke care pathways.

Background: In 2010, Greater Manchester (GM) and London centralized acute stroke care services into a reduced number of hyperacute stroke units, with local stroke units providing on-going care nearer patients' homes.

Objective: To explore the impact of centralized acute stroke care pathways on the experiences of patients.

Design: Qualitative interview study.

Involving Caregivers of People With Dementia to Validate Booklets on Food-Related Activities: A Qualitative Think-Aloud Study.

This study is the first to explore informal dementia caregivers' perceptions and outlook on written materials about all food-related processes: shopping, food preparation, and eating. The aim of the study was to develop and evaluate the content, format, and usefulness of two separate booklets (one newly developed and one existing) on food-related processes. Twenty dementia caregivers were provided with one of the two booklets, and a Think-Aloud method was used to gather information about their views on the booklets.

Identifying the most important outcomes for systematic reviews of interventions for rhinosinusitis in adults: working with Patients, Public and Practitioners.

Introduction: Promoting the assessment of health interventions using outcomes that matter to patients and practitioners is a key principle of Cochrane. Cochrane UK therefore commissioned the OMIPP project: Outcomes that are Most Important for Patients, Public and Practitioners to identify the outcomes they felt most important and should be evaluated in Cochrane reviews of health interventions for Chronic Rhinosinusitis (CRS).

Methodology: Using direct emailing, social media and printed cards, an online survey was distributed to a wide range of people involved in the care of patients with CRS.

Dementia informal caregiver obtaining and engaging in food-related information and support services.

As dementia progresses, caregivers increasingly have to manage the decline of food-related abilities with little outside information or input from support services The provision of food coping skills and knowledge can lessen the burden on caregivers. However, there is little research on caregivers' perspectives on food-related services. This paper reports on a qualitative study to investigate informal caregivers' experiences of, and views on, food-related information and support services in dementia.

Impact of dementia progression on food-related processes: a qualitative study of caregivers' perspectives.

As dementia progresses, one area that can help maintain connection and memories with others is within the food domain. There is little research in this area particularly from the informal caregivers' perspectives. Therefore, a qualitative study was conducted to explore the impact of dementia progression on food-related processes from the perspectives of informal caregivers.

Prognostic impact of [18F]fluorothymidine and [18F]fluoro-D-glucose baseline uptakes in patients with lung cancer treated first-line with erlotinib.

Unlabelled: 3'-deoxy-3'-[(18)F]fluoro-L-thymidine (FLT) and 2'-deoxy-2'-[(18)F]fluoro-D-glucose (FDG) are used to visualize proliferative and metabolic activity of tumors. In this study we aimed at evaluating the prognostic value of FLT and FDG uptake measured by positron emission tomography (PET) in patients with metastatic non-small cell lung cancer (NSCLC) prior to systemic therapy with erlotinib. FLT and FDG maximum standardized uptake (SUVmax) values per patient were analyzed in 40 chemotherapy naive patients with advanced NSCLC (stage IV) before treatment with erlotinib.

Early prediction of nonprogression in advanced non-small-cell lung cancer treated with erlotinib by using [(18)F]fluorodeoxyglucose and [(18)F]fluorothymidine positron emission tomography.

Purpose: Positron emission tomography (PET) with both 2'-deoxy-2'-[(18)F]fluoro-D-glucose (FDG) and 3'-[(18)F]fluoro-3'-deoxy-L-thymidine (FLT) was evaluated with respect to the accuracy of early prediction of nonprogression following erlotinib therapy, independent from epidermal growth factor receptor (EGFR) mutational status, in patients with previously untreated advanced non-small-cell lung cancer (NSCLC).

Patients And Methods: Thirty-four patients with untreated stage IV NSCLC were evaluated in this phase II trial. Changes in FDG and FLT uptake after 1 (early) and 6 (late) weeks of erlotinib treatment were compared with nonprogression measured by computed tomography after 6 weeks of treatment, progression-free survival (PFS), and overall survival (OS).
