CSF/serum albumin ratio in dementias : a cross-sectional study on 1861 patients

A connection between dementias and blood-brain barrier (BBB) dysfunction has been suggested, but previous studies have yielded conflicting results. We examined cerebrospinal fluid (CSF)/serum albumin ratio in a large cohort of patients diagnosed with Alzheimer's disease (AD, early onset [EAD, n = 130], late onset AD [LAD, n = 666]), vascular dementia (VaD, n = 255), mixed AD and VaD (MIX, n = 362)

Efficacy of the CDK inhibitor dinaciclib in vitro and in vivo in T-cell acute lymphoblastic leukemia

T-cell acute lymphoblastic leukemia (T-ALL) is a heterogeneous disease of the blood affecting children, adolescents and adults. Although current treatment protocols for T-ALL have improved overall survival, a portion of T-ALL patients still experiences treatment failure. Thus, the development of novel therapies is needed. In this study, we used several patient-derived T-ALL cell lines to screen fo

Neutron tomographic imaging of bone-implant interface : Comparison with X-ray tomography

Metal implants, in e.g. joint replacements, are generally considered to be a success. As mechanical stability is important for the longevity of a prosthesis, the biological reaction of the bone to the mechanical loading conditions after implantation and during remodelling determines its fate. The bone reaction at the implant interface can be studied using high-resolution imaging. However, commonly

Association of the oestrogen receptor beta with hormone status and prognosis in a cohort of female patients with colorectal cancer

Background The oestrogen receptor beta (ERβ) is the predominant oestrogen receptor in the normal colon mucosa and has been reported to exert anti-proliferative and pro-apoptotic effects. However, the role of ERβ in colorectal cancer (CRC) progression remains unclear. Aim To investigate the role of ERβ and its association with hormone status and lifestyle indicators in a female cohort of patients w

New Genes Causing Hereditary Parkinson’s Disease or Parkinsonism

Purpose of Review: This article reviews was to review genes where putative or confirmed pathogenic mutations causing Parkinson’s disease or Parkinsonism have been identified since 2012, and summarizes the clinical and pathological picture of the associated disease subtypes. Recent Findings: Newly reported genes for dominant Parkinson’s disease are DNAJC13, CHCHD2, and TMEM230. However, the evidenc

Strategic roadmap for an early diagnosis of Alzheimer's disease based on biomarkers

The diagnosis of Alzheimer's disease can be improved by the use of biological measures. Biomarkers of functional impairment, neuronal loss, and protein deposition that can be assessed by neuroimaging (ie, MRI and PET) or CSF analysis are increasingly being used to diagnose Alzheimer's disease in research studies and specialist clinical settings. However, the validation of the clinical usefulness o

Migraine associated with altitude : results from a population-based study in Nepal

Background and purpose: A 1988 pilot study in Peru suggested an association between migraine and chronic exposure to high altitude. This study provides epidemiological evidence corroborating this. Methods: In a cross-sectional nationwide population-based study, a representative sample of Nepali-speaking adults were recruited through stratified multistage cluster sampling. They were visited at home

Coagulopathy and haemorrhagic progression in traumatic brain injury : advances in mechanisms, diagnosis, and management

Normal haemostasis depends on an intricate balance between mechanisms of bleeding and mechanisms of thrombosis, and this balance can be altered after traumatic brain injury (TBI). Impaired haemostasis could exacerbate the primary insult with risk of initiation or aggravation of bleeding; anticoagulant use at the time of injury can also contribute to bleeding risk after TBI. Many patients with TBI

Online lurking and offline action: young people, social media, and (non-)participation

Research has described political participation as becoming ever more individualised (eg Bennett & Segerberg, 2013). This has been argued to be connected to the general individualisation of society, but also to affordances made possible by new media. One line of research explains political participation combining selective benefits (Olson, 1965), psychological factors (Klandermans & van Ste

Dementia with Lewy Body (DLB) Symptoms Hidden within the Diagnosis “Dementia Not Otherwise Specified” a Cross-Sectional Study in 40 Swedish Nursing Homes.

Background: Dementia with Lewy Body (DLB) is a neurocognitive disorder with core features, such as Parkinsonism, visual hallucinations, and fluctuating cognition/ excessive daytime sleepiness, and supportive features, such as rapid eye movement sleep behaviour disorder. DLB is often misdiagnosed and unrecognized in elderly individuals. A diagnosis of DLB is important because of the risk of hyperse

Novel risk genes for systemic lupus erythematosus predicted by random forest classification

Genome-wide association studies have identified risk loci for SLE, but a large proportion of the genetic contribution to SLE still remains unexplained. To detect novel risk genes, and to predict an individual's SLE risk we designed a random forest classifier using SNP genotype data generated on the "Immunochip" from 1,160 patients with SLE and 2,711 controls. Using gene importance scores defined b

Sensitivity of Sentinel-1 backscatter to characteristics of buildings

In this study, Sentinel-1 interferometric wide swath (IW) mode backscatter is analysed with respect to physical parameters of buildings in Tallinn, Estonia. Dependence on height, alignment, density, shape, and material is shown and discussed. Distribution of backscatter was estimated with respect to each of the parameters, and a correlation matrix of all physical parameters and backscatter values

A finite deformation continuum modelling framework for curvature effects in fibre-reinforced nanocomposites

Motivated by experimental findings on one-dimensional nano-materials, this contribution focusses on the elaboration of a fibre curvature based higher-order gradient contribution to the stored energy function in a finite deformation setting. The presented approach is based on the fundamental theoretical developments for fibre-reinforced composites presented by Spencer and Soldatos (2007), which tak

Bare and Effective Charge of Mesoporous Silica Particles

We develop and combine a novel numerical model, within the Poisson-Boltzmann framework, with classical experimental titration techniques for mesoporous silica particles to study the charging behavior as both pH and the amount of monovalent salt are varied. One key finding is that these particles can be considered to have an effectively or apparent electroneutral inner core with an effectively char

Monomeric and fibrillar α-synuclein exert opposite effects on the catalytic cycle that promotes the proliferation of Aβ42 aggregates

The coaggregation of the amyloid-β peptide (Aβ) and α-synuclein is commonly observed in a range of neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. The complex interplay between Aβ and α-synuclein has led to seemingly contradictory results on whether α-synuclein promotes or inhibits Aβ aggregation. Here, we show how these conflicts can be rationalized and resolved by de

Two dynamin-like proteins stabilize FtsZ rings during Streptomyces sporulation

During sporulation, the filamentous bacteria Streptomyces undergo a massive cell division event in which the synthesis of ladders of sporulation septa convert multigenomic hyphae into chains of unigenomic spores. This process requires cytokinetic Z-rings formed by the bacterial tubulin homolog FtsZ, and the stabilization of the newly formed Z-rings is crucial for completion of septum synthesis. He

Implementation of a multiplexed structured illumination method to achieve snapshot multispectral imaging

An instantaneous multispectral imaging setup based on frequency recognition algorithm for multiple exposures (FRAME) is presented and demonstrated experimentally. With this implementation of FRAME, each light source is uniquely encoded with a spatial modulation and the corresponding fluorescent responses pertaining to each maintain the same unique encoding. This allows the extraction of each sourc
