Role of the axonal initial segment in psychiatric disorders : function, dysfunction, and intervention

The progress of developing effective interventions against psychiatric disorders has been limited due to a lack of understanding of the underlying cellular and functional mechanisms. Recent research findings focused on exploring novel causes of psychiatric disorders have highlighted the importance of the axonal initial segment (AIS), a highly specialized neuronal structure critical for spike initi

Glycomic and transcriptomic response of GSC11 glioblastoma stem cells to STAT3 phosphorylation inhibition and serum-induced differentiation

A glioblastoma stem cell (GSC) line, GSC11, grows as neurospheres in serum-free media supplemented with EGF (epidermal growth factor) and bFGF (basic fibroblast growth factor), and, if implanted in nude mice brains, will recapitulate high-grade glial tumors. Treatment with a STAT3 (signal transducer and activator of transcription 3) phosphorylation inhibitor (WP1193) or 10% FBS (fetal bovine serum

Comparative evaluation of four bacteria-specific primer pairs for 16S rRNA gene surveys

Bacterial taxonomic community analyses using PCR-amplification of the 16S rRNA gene and high-throughput sequencing has become a cornerstone in microbiology research. To reliably detect the members, or operational taxonomic units (OTUs), that make up bacterial communities, taxonomic surveys rely on the use of the most informative PCR primers to amplify the broad range of phylotypes present in up-to

The protagonist projection hypothesis

The protagonist projection hypothesis was formulated by Holton (1997) in order to account for cases where the speaker seems to utter contradictory statements. Holton argues that in these cases the speaker projects herself into the mind of someone else. Three different sentence-types have been classified as examples of protagonist projection: (i) sentences with factive verbs (tell+wh, know), (ii) s

On the complexity of screening detected abdominal aortic aneurysms : A retrospective observational multicenter cohort study

BACKGROUND: Ultrasound screening for abdominal aortic aneurysms (AAA) has been shown to decrease aneurysm related mortality. Likely by providing an opportunity to intervene while the aneurysm is still intact, but possibly also when and the anatomy still relatively uncomplicated which would provide a less complex procedure. Our aim was to retrospectively investigate the complexity of repair for scr

Germline heterozygous variants in genes associated with familial hemophagocytic lymphohistiocytosis as a cause of increased bleeding

Familial hemophagocytic lymphohistiocytosis (FHL) is caused by biallelic variants in genes regulating granule secretion in cytotoxic lymphocytes. In FHL3–5, the affected genes UNC13D, STX11 and STXBP2 have further been shown to regulate the secretion of platelet granules, giving rise to compromised platelet function. Therefore, we aimed to investigate platelet degranulation in patients heterozygou

Plant-pollinator networks in semi-natural grasslands are resistant to the loss of pollinators during blooming of mass-flowering crops

Mass-flowering crops lead to spatial redistributions of pollinators and to transient shortages within nearby semi-natural grasslands, but the impacts on plant-pollinator interactions remain largely unexplored. Here, we characterised which pollinator species are attracted by oilseed rape and how this affected the structure of plant-pollinator networks in nearby grasslands. We surveyed 177 networks

Diabetes is associated with increased hand pain in erosive hand osteoarthritis : data from a population-based study

OBJECTIVE: To explore factors related to hand pain in persons with radiographic hand osteoarthritis (OA).METHODS: Persons in the Musculoskeletal Pain in Ullensaker Study with radiographic hand OA (≥1 joint with Kellgren/Lawrence grade ≥2) were included (n = 530). We examined the cross-sectional association between possible explanatory variables and hand pain in the entire sample and in 2 hand OA p

Concentration of perfluorinated compounds and cotinine in human foetal organs, placenta, and maternal plasma

Background Perfluoroalkyl substances (PFASs) are bio-accumulative pollutants, and prenatal exposure to PFASs is believed to impact human foetal development and may have long-term adverse health effects later in life. Additionally, maternal cigarette smoking may be associated with PFAS levels. Foetal exposure has previously been estimated from umbilical cord plasma, but the actual concentration in

Retrograde signalling caused by heritable mitochondrial dysfunction is partially mediated by ANAC017 and improves plant performance

Mitochondria are crucial for plant viability and are able to communicate information on their functional status to the cellular nucleus via retrograde signalling, thereby affecting gene expression. It is currently unclear if retrograde signalling in response to constitutive mitochondrial biogenesis defects is mediated by the same pathways as those triggered during acute mitochondrial dysfunction.

Establishment and characterization of an orthotopic patient-derived Group 3 medulloblastoma model for preclinical drug evaluation

Medulloblastomas comprise a heterogeneous group of tumours and can be subdivided into four molecular subgroups (WNT, SHH, Group 3 and Group 4) with distinct prognosis, biological behaviour and implications for targeted therapies. Few experimental models exist of the aggressive and poorly characterized Group 3 tumours. In order to establish a reproducible transplantable Group 3 medulloblastoma mode

Combined emulsifying capacity of polysaccharide particles of different size and shape

The aim of this study is to understand mixed systems of two types of particles with different size and shape, quinoa starch granules (NQ) and cellulose nanocrystals (CNC), to stabilize oil-in-water (O/W) emulsions. This study considers the extent of Pickering stabilization with respect to which particle type dominates at droplet interfaces and how stability is affected by the addition of one parti

Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique

Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. During mining activities, sulfide minerals, which are commonly associated with coal, are exposed to oxygen and water, leading to the generation of acid m
