The objective of proteomics is the study of proteins (including their structure elucidation, the characterization of their role in biochemical process, the detection and identification of anomalous modifications in their structures and behavior, etc.) from both a qualitative and quantitative point of view. These studies have to face several difficulties as (a) the intrinsic complexity of protein molecules, (b) the low concentrations of the studied proteins, (c) the complexity of the biological samples (which could lead to interferences from the components of these matrixes), etc...

We describe the usage of hydrolytic enzymes for the innovative, green and simple microextraction of manganese in food samples. The ultrasound assisted-enzyme based hydrolytic microextraction method (UA-EH-ME) was applied for the separation and determination of manganese in food samples prior to its micro-sampling flame atomic absorption spectrometric determination (MS-FAAS). Analytical parameters influenced on the enzyme based hydrolytic microextraction method such as pH, type of enzyme, amount of enzyme, temperature and time of ultrasonic waves were fully evaluated and optimized by using mg level of NCS ZC73033 scallion certified reference material...

Obstructive sleep apnea (OSA) as a multifactorial disease is treated with continuous positive airway pressure (CPAP) as the gold standard. Yet, if patients suffer from CPAP incompliance, traditional OSA surgery only targets morphological changes of the upper airway while neglecting functional issues. With the advent of upper airway stimulation, and in particular hypoglossal nerve stimulation as a treatment option, a highly effective, clinically proven and functional therapy with good evidence is available. This article gives a comprehensive overview of current and upcoming hypoglossal nerve stimulation systems (Inspire, ImThera, and Nyxoah), the specific advantages of this approach, the selection criteria and screening process, relevant clinical data, and a description of the different implantation procedures...

Advanced practice providers (APPs) are increasingly being used in a variety of healthcare settings to provide care, treatment, and services to patients with cancer. They are also being deployed to acute oncologic settings to enhance patient care delivery and address the ever-evolving needs of patients in academic medicine. In response, the University of Texas MD Anderson Cancer Center developed a series of innovative clinical programs staffed by acute care APPs. These provide an opportunity to rapidly adapt to the acute care needs of patients with cancer while fostering the professional development of APPs within the full scope of their oncologic clinical practice...

After two decades of focused development and some recent clinical successes, cell and gene therapy (CGT) is emerging as a promising approach to personalized medicines. Genetically engineered cells as a medical modality are poised to stand alongside or in combination with small molecule and biopharmaceutical approaches to bring new therapies to patients globally. Big pharma can play a vital role in industrializing CGT by focusing on diseases with high un-met medical need and compelling genetic evidence. Pharma should invest in manufacturing and supply chain solutions that deliver reproducible, high quality therapies at a commercially viable cost...

REVIEW
Anna Watermann, Juergen Brieger
Even though cancer treatment has improved over the recent decades, still more specific and effective treatment concepts are mandatory. Surgical removal is not always possible, metastases are challenging and chemo- and radiotherapy can not only have severe side-effects but also resistances may occur. To cope with these challenges more efficient therapies with fewer side-effects are required. One promising approach is the use of drug delivery vehicles. Here, mesoporous silica nanoparticles (MSN) are discussed as biodegradable drug carrier to improve efficacy and reduce side-effects...

Carbon nanotubes-transition metal oxide systems are intensively studied due to their excellent properties for electrochemical applications. In this work, an innovative procedure is developed for the synthesis of vertically aligned multi-walled carbon nanotubes (VACNTs) coated with transition metal oxide nanostructures. VACNTs are grown by plasma enhanced chemical vapor deposition and coated with a manganese-based metal organic precursor (MOP) film based on manganese acetate solution. Subsequent UV pulsed laser irradiation induces the effective heating-decomposition of the MOP leading to the crystallization of manganese oxide nanostructures on the VACNT surface...

We investigated the evolution process of collaborative inter-organizational network of the research and development (R&D) on monoclonal antibody (mAb) over the past 30 years. The annual detection of the collaboration network provides dynamics on network structures and relationship changes among different organizations. Our research showed continuous growth of the network's scale and complexity due to the constant entry of new organizations and the forging of new partnering relationships. The evolving topological features reveal a core-periphery structure that became clearer over time and an increasing heterogeneity within the collaborative mAb R&D network...

Near infrared (NIR) light triggered phototherapy including photothermal therapy (PTT) and photodynamic therapy (PDT) affords superior outcome in cancer treatment. However, the reactive oxygen species (ROS) generated by NIR-excited upconversion nanostructure is limited by the feeble upconverted light which cannot activate PDT agents efficiently. Here, an IR-808 dye sensitized upconversion nanoparticle (UCNP) with a chlorin e6 (Ce6)-functionalized silica layer is developed for PDT agent. The two booster effectors (dye-sensitization and core-shell enhancement) synergistically amplify the upconversion efficiency, therefore achieving superbright visible emission under low 808 nm light excitation...

The number of computed tomography (CT) scans being done for children all over the world is on the rise ever since the advent of Multi-Detector CT (MDCT). However, CT is a potential source of harmful ionizing radiation, and children are more susceptible to its adverse effects. It is essential for the pediatrician as well as the radiologist to be aware of some important principles and guidelines, by following which, radiation exposure to the child can be minimized to the bare essential. It is important to have knowledge of the valid and justifiable indications of CT for the child, the correct technique of performing the scan, and the new technological innovations now available on modern scanners that help to minimize radiation dose...

Local dementia education initiatives exist in schools but it is unclear what the wider uptake of such programmes are. A self-created survey was sent to staff in a number of secondary schools (teaching ages 11-16) across Sussex, England. Sixty schools responded to the survey (response rate = 58%). While the majority of schools expressed an interest in including some form of dementia education within their school in the future, only nine schools (15%) currently had dementia education embedded within their curriculum...

Chemokines are key signals in the immune system and play an important role as proinflammatory mediators in the pathology of inflammatory bowel disease and colorectal cancer, making them an important target for therapy. Recombinant lactic acid bacteria (LAB) were engineered to bind CC and CXC chemokines by displaying chemokine-binding proteins evasin-1, evasin-3 and evasin-4 on their surface. Evasin genes were cloned into lactococcal surface display vector and overexpressed in L. lactis NZ9000 and NZ9000ΔhtrA in fusion with secretion signal and surface anchor...

Objective: Prosthetic sockets are custom made for each amputee, yet there are no quantitative tools to determine the appropriateness of socket fit. Ensuring a proper socket fit can have significant effects on the health of residual limb soft tissues and overall function and acceptance of the prosthetic limb. Previous work found that elevated vacuum pressure data can detect movement between the residual limb and the prosthetic socket; however, the correlation between the two was specific to each user. The overall objective of this work is to determine the relationship between elevated vacuum pressure deviations and prosthetic socket fit...

The notion of development blocks (Dahmén, 1950, 1991) suggests the co-evolution of technologies and industries through complementarities and the overcoming of imbalances. This study proposes and applies a methodology to analyse development blocks empirically. To assess the extent and character of innovational interdependencies between industries the study combines analysis of innovation biographies and statistical network analysis. This is made possible by using data from a newly constructed innovation output database for Sweden...
