#1
L A Pereira, A F B Abreu, I C Vieira Júnior, L P M Pires, M A P Ramalho
Common bean producers in Brazil tend to grow plants as upright as possible. Because the control of this trait involves a large number of genes, recurrent selection (RS) is the best approach for successful plant improvement. Because plant architecture (PA) is evaluated using scores and usually has high heritability, RS for PA is performed through visual selection in generation S0. The aim of the present study was to evaluate selection progress and investigate whether this progress varies with the number of selected progenies or the generation evaluated...

The Swedish health care system has successively moved toward increased market-orientation, which has raised concerns as to whether Sweden still offers health on equal terms. To explore this issue, this study aimed (i) to assess if the principles of horizontal equity (equal access for equal need regardless of socio-economic factors) are met in Northern Sweden 2006-14; and (ii) to explore the contribution of different factors to the inequalities in access along the same period. Data came from cross sectional surveys known in 2006, 2010 and 2014 targeting 16-84-year-old residents in the four northern-most counties in Sweden...

Background.: Early diagnosis of chronic kidney disease (CKD) facilitates best management in primary care. Testing coverage of those at risk and translation into subsequent diagnostic coding will impact on observed CKD prevalence. Using initial data from 915 general practitioner (GP) practices taking part in a UK national audit, we seek to apply appropriate methods to identify outlying practices in terms of CKD stages 3-5 prevalence and diagnostic coding. Methods.: We estimate expected numbers of CKD stages 3-5 cases in each practice, adjusted for key practice characteristics, and further inflate the control limits to account for overdispersion related to unobserved factors (including unobserved risk factors for CKD, and between-practice differences in coding and testing)...

Background.: Little is known about the quality of general practice care received by patients suffering from multimorbidity. Objectives.: To assess how patients with multimorbidity evaluate their General Practitioners (GPs') performance and to identify factors associated with high patient satisfaction levels. Methods.: Cross-sectional study in Germany using the EUROPEP questionnaire consisting of 23 items with a five-point Likert scale and covering two dimensions: clinical performance of the GP and organisation of care...

Aim.: Studies based on pharmacy medication records have shown suboptimal adherence and persistence of osteoporosis treatment with oral bone sparing drugs (OBSD). Little is known about adherence and persistence of OBSD treatment in primary care. We assessed adherence and persistence of OBSD use of patients in general practices and identified associated factors. Methods.: Using electronic medical records, adherence and persistence of newly prescribed treatment with OBSD in patients from 16 general practices was retrospectively assessed...

BACKGROUND: People diagnosed with cancer following emergency presentation have poorer short-term survival. To what extent this signifies a missed opportunity for earlier diagnosis in primary care remains unclear as little detailed data exist on the patient/general practitioner interaction beforehand. METHODS: Analysis of primary care and regional data for 1802 cancer patients from Northeast Scotland. Adjusted odds ratios (OR) and 95% confidence intervals (CIs) for patient and GP practice predictors of emergency presentation...

Anne Nolan, Richard Layte
The use of direct out-of-pocket payments to finance general practitioner (GP) care by the majority of the population in Ireland is unusual in a European context. Currently, approximately 40 per cent of the population have means-tested access to free GP care, while the remainder must pay the full out-of-pocket cost. In this paper, we use nationally representative data from the Growing up in Ireland (GUI) study to examine the impact of transitions in insurance coverage on GP utilisation among children. GUI surveys two cohorts of nearly 20,000 children (aged 9 months and 9 years at baseline); we use data from the first two waves of each cohort (which covers the period 2007-2012)...

BACKGROUND: Chemotherapy resistance has become a serious challenge in the treatment of breast cancer. Previous studies showed cells can transfer proteins, including those responsible for drug resistance to adjacent cells via exosomes. METHODS: The switches of drug resistance via exosomes transfer were assessed by CellTiter-Blue Viability assay, flow cytometry, and immunostaining analysis. Relative protein levels of Ubiquitin carboxyl terminal hydrolase-L1 (UCH-L1), P-glycoprotein (P-gp), extracellular-signal regulated protein kinase1/2 (ERK1/2), and phospho-extracellular-signal regulated protein kinase1/2 (p-ERK1/2) were measured by Western blot...

Since Ebola virus causes a severe hemorrhagic fever in humans with mortality rates as high as 90%, the rapid and accurate detection of the virus is essential both for controlling the infection and for preventing further transmission. Here, we introduce one-step real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) assays for the rapid and quantitative detection of an Ebola Zaire strain using GP, VP24 or VP40 gene as a target. Routine assay conditions for hydrolysis probe detection were established by the manufacturer's protocol used in the assays...

There are currently no approved therapeutics or vaccines to treat or protect against the severe hemorrhagic fever and death caused by Ebola virus (EBOV). Ebola virus-like particles (EBOV-VLPs) consisting of the matrix protein VP40, the glycoprotein (GP) and the nucleoprotein (NP) are highly immunogenic and protective in non-human primates against Ebola virus disease (EVD). We have constructed a modified vaccinia virus Ankara-Bavarian Nordic(®) (MVA-BN(®)) recombinant co-expressing VP40 and glycoprotein (GP) of EBOV Mayinga and the nucleoprotein (NP) of Taï Forest virus (TAFV) (MVA-BN-EBOV-VLP) to launch non-infectious EBOV-VLPs as a second vaccine modality in the MVA-BN-EBOV-VLP-vaccinated organism...

Ebola virus (EBOV) and Reston virus (RESTV) are members of the Ebolavirus genus which greatly differ in their pathogenicity. While EBOV causes a severe disease in humans characterized by a dysregulated inflammatory response and elevated cytokine and chemokine production, there are no reported disease-associated human cases of RESTV infection, suggesting that RESTV is non-pathogenic for humans. The underlying mechanisms determining the pathogenicity of different ebolavirus species are not yet known. In this study we dissect the host response to EBOV and RESTV infection in primary human monocyte-derived macrophages (MDMs)...

BACKGROUND: Web-based surveys have become a new and popular method for collecting data, but only a few studies have directly compared postal and Web-based surveys among physicians, and none to our knowledge among general practitioners (GPs). OBJECTIVE: Our aim is to compare two modes of survey delivery (postal and Web-based) in terms of participation rates, response times, and completeness of questionnaires in a study assessing GPs' preventive practices. METHODS: This randomized study was conducted in Western Switzerland (Geneva and Vaud) and in France (Alsace and Pays de la Loire) in 2015...

Repair of craniofacial bony defects remains a challenge for surgeons due to the delicate and complex anatomy of the craniofacial skeleton. Stromal cell-derived factor-1α (SDF-1α) is an important chemokine which plays a critical role in the homing of mesenchymal stem cells (MSC), while, the shortcomings including short half-life and easy degradation by enzymes made it in relatively low efficacy. In this work, SDF-1α/chitosan/carboxymeymethy-chitosan nanoparticles (SDF-1α/CS/CMCS NPs) were prepared and characterized for various parameters including morphology, particle size, zeta potential, loading efficiency and the release characteristics from thermosensitive chitosan/β-glycerol phosphate disodium salt (CS/GP) hydrogels...

BACKGROUND: Cigarette smoke (CS) is associated with lower numbers of circulating stem cells and might severely affect their mobilization, trafficking and homing. Our study was designed to demonstrate in an animal model of CS exposure whether CS affects the homing and functional capabilities of bone marrow-derived mesenchymal stem cells (BM-MSCs). METHODS: Guinea pigs (GP), exposed or sham-exposed to CS, were administered via tracheal instillation or by vascular administration with 2...

Repeated anaesthesia may be required in experimental protocols and in daily veterinary practice, but anaesthesia is known to alter physiological parameters in GPs (Cavia porcellus, GPs). This study investigated the effects of repeated anaesthesia with either medetomidine-midazolam-fentanyl (MMF) or isoflurane (Iso) on physiological parameters in the GP. Twelve GPs were repeatedly administered with MMF or Iso in two anaesthesia sets. One set consisted of six 40-min anaesthesias, performed over 3 weeks (2 per week); the anaesthetic used first was randomized...

Multifunctional theranostics have offered some interesting new opportunities for cancer therapy and diagnosis in the last decade. Herein, magnetic mesoporous silica nanoparticles (M-MSNs) were designed and synthesized, then the photosensitizer chlorin e6 (Ce6) and antitumor drug doxorubicin (Dox) were adsorbed onto the M-MSNs. Biocompatible alginate/chitosan polyelectrolyte multilayers (PEM) were assembled on the M-MSNs to achieve a pH-responsive drug delivery system and adsorb P-gp shRNA for reversing the multidrug resistance...

BACKGROUND: Detection of cancer in general practice is challenging because symptoms are diverse. Even so-called alarm symptoms have low positive predictive values of cancer. Nevertheless, appropriate referral is crucial. As 85% of cancer patients initiate their cancer diagnostic pathway in general practice, a Continuing Medical Education meeting (CME-M) in early cancer diagnosis was launched in Denmark in 2012. We aimed to investigate the effect of the CME-M on the primary care interval, patient contacts with general practice and use of urgent cancer referrals...

BACKGROUND: Chlamydia trachomatis (chlamydia) is the most commonly diagnosed sexually transmitted infection (STI) in England; approximately 70% of diagnoses are in sexually active young adults aged under 25. To facilitate opportunistic chlamydia screening in general practice, a complex intervention, based on a previously successful Chlamydia Intervention Randomised Trial (CIRT), was piloted in England. The modified intervention (3Cs and HIV) aimed to encourage general practice staff to routinely offer chlamydia testing to all 15-24 year olds regardless of the type of consultation...
