Brain Tumor Characterization Using Multibiometric Evaluation of MRI

The aim was to evaluate volume, diffusion, and perfusion metrics for better presurgical differentiation between high-grade gliomas (HGG), low-grade gliomas (LGG), and metastases (MET). For this retrospective study, 43 patients with histologically verified intracranial HGG (n = 18), LGG (n = 10), and MET (n = 15) were chosen. Preoperative magnetic resonance data included pre- and post-gadolinium co

Improved calculation of the equilibrium magnetization of arterial blood in arterial spin labeling

PURPOSE: To propose and assess an improved method for calculating the equilibrium magnetization of arterial blood ( M0a), used for calibration of perfusion estimates in arterial spin labeling.METHODS: Whereas standard M0a calculation is based on dividing a proton density-weighted image by an average brain-blood partition coefficient, the proposed method exploits partial-volume data to adjust this

Accuracy of the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity score and the Nottingham risk score in hip fracture patients in Sweden — A prospective observational study

Background: Little is known about accuracy of common risk prediction scores in elderly patients suffering from hip fractures. The objective of this study was to investigate accuracy of the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) score, Portsmouth-POSSUM (P-POSSUM) score and the Nottingham Hip Fracture Score (NHFS) for prediction of mortali

Automation of building permission by integration of BIM and geospatial data

The building permission process is to a large extent an analogue process where much information is handled in paper format or as pdf files. With the ongoing digitalisation in society, there is a potential to automate this process by integrating Building Information Models (BIM) of planned buildings and geospatial data to check if a building conforms to the building permission regulations. In this

Risk of second primary cancer following myeloid neoplasia and risk of myeloid neoplasia as second primary cancer : a nationwide, observational follow up study in Sweden

Background: Although advances in the treatment of myeloid neoplasms have led to improved patient survival, this improvement has been accompanied by an increased risk of second primary cancer (ie, the risk of another cancer after myeloid neoplasia). We aimed to assess bi-directional associations between myeloid cancers and other cancers—ie, development of second primary cancer in patients who have

Degradation of human secretory immunoglobulin A by Blastocystis

Microbial immunoglobulin A (IgA) proteases cleave human secretory IgA, promoting the mucosal adhesion of pathogens. To investigate if the enteric protozoan Blastocystis degrades human secretory IgA, cell lysate and conditioned medium from two species were exposed to immunoglobulin A. Secretory IgA was cleaved by both cell lysate and conditioned medium with mainly cysteine proteinase activity in B.

Acceptability of electric vehicle aimed measures: Effects of norm activation, perceived justice and effectiveness

In this study a model was applied on consumer acceptance of commonly implemented EV focused measures. The model is based on a norm-activation process as defined in the Value-Belief-Norm theory and the Norm-Activation Model. The study was based on a questionnaire survey study on three groups of car owners; conventional fossil fuel vehicle owners (CV, n = 312, owners of vehicles run on alternative f

Combining smart card data with data from user-mediated mobile platform survey for longitudinal study of travel behaviour

Smart card data and survey data have different characteristics, which combined have the potential to enrich the total level of information as well as to reduce inherent biases in each dataset. This paper describes a fruitful procedure to use survey data from a smartphone application-based travel survey with prompted recall to validate data from smart card transactions in the same geographical area

Experiences of Screening for Postpartum Depression in Non-Native-Speaking Immigrant Mothers in the Swedish Child Health Services. Nurses’ and Mothers’ Perspectives.

Postpartum depression (PPD) är ett globalt folkhälsoproblem. Mödrar som migrerar till ett annat land har en ökad risk att drabbas av PPD. Före-komsten av PPD bland utlandsfödda mödrar beräknas vara så hög som 20 procent, vilket nästan är dubbelt så hög som bland inhemsk västerländsk befolkning. Asylsökande och flyktingar är särskilt sårbara grupper som löper en ännu högre risk att drabbas, speciel

The study based on the descriptive analytical methodology, using the tools of the modern narrative theories, to examine the Saudi short stories. The study shows that the dialogue performs diverse functions linked to narrative’s transformations in the text. Also some of the dialogues cover the text and other contained different partial narratives, or parallel stories to the central story. The study

Solitary Wave Solutions to a Class of Modified Green–Naghdi Systems

We provide the existence and asymptotic description of solitary wave solutions to a class of modified Green–Naghdi systems, modeling the propagation of long surface or internal waves. This class was recently proposed by Duchêne et al. (Stud Appl Math 137:356–415, 2016) in order to improve the frequency dispersion of the original Green–Naghdi system while maintaining the same precision. The solitar

Semaglutide induces weight loss in subjects with type 2 diabetes regardless of baseline BMI or gastrointestinal adverse events in the SUSTAIN 1 to 5 trials

Aims: To assess the effect of baseline body mass index (BMI) and the occurrence of nausea and/or vomiting on weight loss induced by semalgutide, a once-weekly glucagon-like peptide 1 analogue for the treatment of type 2 diabetes. Semaglutide demonstrated superior reductions in HbA1c and superior weight loss (by 2.3-6.3 kg) versus different comparators across the SUSTAIN 1 to 5 trials; the contribu

A fibrin biofilm covers blood clots and protects from microbial invasion

Hemostasis requires conversion of fibrinogen to fibrin fibers that generate a characteristic network, interact with blood cells, and initiate tissue repair. The fibrin network is porous and highly permeable, but the spatial arrangement of the external clot face is unknown. Here we show that fibrin transitioned to the blood-air interface through Langmuir film formation, producing a protective film

Nanostructure and biomolecule interactions : Characterizing the complex

Nanostructures are found everywhere in our environment, of either natural oranthropogenic origin. Volcanoes emit them, breakdown of plastic releases them, andthey are even produced in candlelight. Designed nanostructures are used in sunscreen,food products, electronics and many more readily available products. Still, there are alot of things we do not know about their behavior. To call them miniscThis thesis presents the results of studies done on various biomolecules and their interactions with nanomaterials. The biomolecule sources are everything from purified, single proteins to the complicated mixture of blood serum and cell culture media. Similarly, the nanomaterial sources vary from spherical titanium dioxide, gold, and polystyrene nanoparticles to novel nanowires of gallium arsenide

Dynamic evaluation of the immune infiltrate and immune function genes as predictive markers for neoadjuvant chemotherapy in hormone receptor positive, HER2 negative breast cancer

Gene expression (GE) signatures and Tumor Infiltrating Lymphocytes (TIL) enumeration are predictive for response to neoadjuvant chemotherapy in HR- and in HER2+ breast cancer, but data are conflicting in HR+/HER2- disease. This study aimed to explore their predictive value in this subset, measured both at baseline and after short exposure to chemotherapy. Specifically, the PROMIX phase 2 trial enr
