The extent to which newly developed blood-based biomarkers could reduce screening costs in secondary prevention trials of Alzheimer's disease is mostly unexplored. We collected plasma amyloid-β42/40, apolipoprotein E ϵ4 status and amyloid PET at baseline in 181 cognitively unimpaired participants [the age of 72.9 (5.3) years; 61.9% female; education of 11.9 (3.4) years] from the Swedish BioFINDER-
This paper investigates the possibility of using empirical tool life models to predict tool life in a side milling application in a medium carbon steel, C 45E. To do this, an extensive dataset containing 46 data points with different machining parameters are produced. Four different empirical models: Taylor's equation, Colding's equation and Extended Taylor both using depth of cut and feed as well
Background: The apolipoprotein E (APOE) ε4 allele is associated with higher cholesterol levels, and an increased risk of developing Alzheimer’s disease (AD) and amyloid-related imaging abnormalities after initiation of amyloid-modifying therapies. A worse cognitive response to cholinesterase inhibitor (ChEI) treatment and longitudinal outcome in APOE ε4-carriers has been observed. Based on these c
Nontypeable Haemophilus influenzae (NTHi) causes otitis media and is commonly found in patients with chronic obstructive pulmonary disease (COPD). Adhesins are important for bacterial attachment and colonization. Protein E (PE) is a recently characterized ubiquitous 16 kDa adhesin with vitronectin-binding capacity that results in increased survival in serum. In addition to PE, NTHi utilizes Haemop
A new member of the human cystatin superfamily, called cystatin E, has been found by expressed sequence tag (EST) sequencing in amniotic cell and fetal skin epithelial cell cDNA libraries. The sequence of a full-length amniotic cell cDNA clone contained an open reading frame encoding a putative 28-residue signal peptide and a mature protein of 121 amino acids, including four cysteine residues and
Prostaglandin (PG) E(2) (PGE(2)) plays a predominant role in promoting colorectal carcinogenesis. The biosynthesis of PGE(2) is accomplished by conversion of the cyclooxygenase (COX) product PGH(2) by several terminal prostaglandin E synthases (PGES). Among the known PGES isoforms, microsomal PGES type 1 (mPGES-1) and type 2 (mPGES-2) were found to be overexpressed in colorectal cancer (CRC); howe
A set of 165 strains of different staphylococcal species, 67 Staphylococcus aureus, 71 novobiocin-sensitive coagulase-negative staphylococci (CNS) and 27 novobiocin-resistant CNS was used. The oxacillin and methicillin MICs were recorded after 24 and 42 h of incubation at 35 degrees C and at 30 degrees C. Significantly higher MICs were recorded at 30 degrees C compared with 35 degrees C. While a p
Haemophilus influenzae protein E (PE) is a 16 kDa adhesin that induces a pro-inflammatory immune response in lung epithelial cells. The active epithelial binding region comprising amino acids PE 84-108 also interferes with complement-mediated bacterial killing by capturing vitronectin (Vn) that prevents complement deposition and formation of the membrane attack complex (MAC). Here, the interaction
We identified apolipoprotein E (ApoE) as one of the proteins that are found in complex with complement component C4d in pooled synovial fluid of rheumatoid arthritis (RA) patients. Immobilized human ApoE activated both the classical and the alternative complement pathways. In contrast, ApoE in solution demonstrated an isoform-dependent inhibition of hemolysis and complement deposition at the level
Inappropriate surface expression of voltage-gated Ca(2+)channels (CaV) in pancreatic ß-cells may contribute to the development of type 2 diabetes. First, failure to increase intracellular Ca(2+) concentrations at the sites of exocytosis impedes insulin release. Furthermore, excessive Ca(2+) influx may trigger cytotoxic effects. The regulation of surface expression of CaV channels in the pancreatic
Cathepsin E (CTSE), an aspartic proteinase, is differentially expressed in the metaplasia-dysplasia-neoplasia sequence of gastric and colon cancer. We evaluated CTSE in Barrett's esophagus (BE) and cancer because increased CTSE levels are linked to improved survival in several cancers, and other cathepsins are up-regulated in BE and esophageal adenocarcinoma (EAC). A total of 273 pretreatment tiss
Shared electric scooters (e-scooters) are widely promoted as a low-carbon urban transport solution. However, their environmental impact depends on lifespan, operations, and modal shift. This study evaluates life cycle greenhouse gas emissions of shared e-scooters operating in Dubai, UAE. A cradle-to-grave life cycle assessment is conducted, considering manufacturing, transportation, use phase elec
Winner of the 1938 Littoriali della Cultura e dell’Arte, the project for a Hotel-Refuge in Valmalenco (2000 m altitude) by Gianni Albricci (1916-2001) and Marco Zanuso (1916-2001) was conceived by two young students from the Faculty of Architecture at the Politecnico di Milano. The skillful design combines traditional alpine materials with innovative solutions, reflecting the autarkic policies of
This paper analysis sexual scripts theory in relation to gay men courtship, love relationships, and casual sex. The aim is to understand how gay masculinity is evolving in the 21st Century. Previous research has reinforced the concept that gay men follow heterosexual masculinity and scripts in their relationships with other men. Here, analysing data from the most used gay dating app ‘Grindr’, we t
