Body Composition in Late Midlife as a Predictor of Accelerated Age-associated Deficit-accumulation From Late Midlife into Old Age: A Longitudinal Bir…

2022

Abstract Background Body mass index (BMI) may not be an optimal predictor of frailty as its constituents, lean and fat mass, may have opposite associations with frailty. Methods A linear mixed model analysis was performed in the Helsinki Birth Cohort Study (n = 2 000) spanning from 57 to 84 years. A 39-item frailty index (FI) was calculated on three occasions over 17 years. Body composition in late midlife included BMI, percent body fat (%BF), waist-to-hip ratio (WHR), lean mass index (LMI), and fat mass index (FMI). Results Mean FI levels increased by 0.28%/year among men and by 0.34%/year among women. Among women, per each kg/m2 higher BMI and each unit higher %BF the increases in FI leve…

Alkoholinkäytön aiheuttama liikennekuoleman riski Suomessa

2023

Tässä tutkimuksessa analysoidaan juopumuksen asteen vaikutusta kuolemaan johtavan liikenneonnettomuuden riskiin moderneilla tilastollisilla menetelmillä. Tutkimuksen pääaineistona ovat vuosina 2005–2014 Suomessa tapahtuneet kuolemaan johtaneet moottoriajoneuvo-onnettomuudet, joissa oli mukana henkilöauto aiheuttajana tai muuna osallisena. Pääaineistoa täydennetään ratsiatutkimuksista julkaistuilla tilastoilla. Keskeisiä käytettyjä mittareita ovat riskisuhde sekä vakioitu riskisuhde, josta on poistettu sekoittavien muuttujien vaikutusta. Tutkimuksen ensimmäisenä tavoitteena on selvittää, miten pieni veren alkoholipitoisuus alkaa lisätä liikenneonnettomuuden riskiä, ja toisena tavoitteena on …

Nanomechanics of individual aerographite tetrapods

2017

Carbon-based three-dimensional aerographite networks, built from interconnected hollow tubular tetrapods of multilayer graphene, are ultra-lightweight materials recently discovered and ideal for advanced multifunctional applications. In order to predict the bulk mechanical behaviour of networks it is very important to understand the mechanics of their individual building blocks. Here we characterize the mechanical response of single aerographite tetrapods via in situ scanning electron and atomic force microscopy measurements. To understand the acquired results, which show that the overall behaviour of the tetrapod is governed by the buckling of the central joint, a mechanical nonlinear mode…

The emerging role of 3D printing in the fabrication of detection systems

2021

Abstract 3D printing is fast evolving as an additive manufacturing technique that has been adopted in (bio)analytical science because of the ample variety of materials and technologies currently available for highly affordable prototyping. This review focuses on the unique characteristics of 3D printing for manufacturing of optical and electrochemical detection systems, and sampling interfaces for analytical purposes using fused deposition modelling, vat polymerization (stereolithography and digital light processing) and photopolymer inkjet printing. The majority of works surveyed within the time span of mid-2018 to mid-2020 encompassed the fabrication of several components of the detection…

Teacher Training for Children with Autism Spectrum Disorders in Finland

2019

This chapter first provides a short description of the historical background and development of special education teacher training in Finland. The relationship between special education and teaching pupils with autism spectrum disorder (ASD) is covered by chronologically presenting the main events, turning points, publications, and people that have had a significant effect on the education of pupils with ASD in Finland. This is followed by a description of the organization of teacher training, in general, and the particular characteristics of teaching pupils with ASD. In the context of ASD, it is essential to examine questions concerning the link between learning as social practice and the …

Genomic structure and functional characterization of the human ADAM10 promoter

2005

The ADAM10 gene encodes a membrane-bound disintegrin-metalloproteinase, which, after overexpression in an Alzheimer disease (AD) mouse model, prevents amyloid pathology and improves long-term potentiation and memory. Because enhancing ADAM10 expression appears to be a reasonable approach for treatment of AD, we functionally analyzed the ADAM10 gene. Both human and mouse ADAM10 genes comprise approximately 160 kbp, are composed of 16 exons, and are evolutionarily highly conserved within 500 bp upstream of either translation initiation site. By using luciferase reporter assays, we demonstrate that nucleotides -2179 to -1 upstream of the human ADAM10 translation initiation site represent a fun…

Genomic organization and promoter characterization of the gene encoding a putative endoplasmic reticulum chaperone, ERp29

2002

Abstract ERp29 is a soluble protein localized in the endoplasmic reticulum (ER) of eukaryotic cells, which is conserved in all mammalian species. The N-terminal domain of ERp29 displays sequence and structural similarity to the protein disulfide isomerase despite the lack of the characteristic double cysteine motif. Although the exact function of ERp29 is not yet known, it was hypothesized that it may facilitate folding and/or export of secretory proteins in/from the ER. ERp29 is induced by ER stress, i.e. accumulation of unfolded proteins in the ER. To gain an insight into the mechanisms regulating ERp29 expression we have cloned and characterized the rat ERp29 gene and studied in details …

Sequence of a sea urchin hsp70 gene and its 5' flanking region.

1990

We report the nucleotide sequence of a 4470-bp fragment derived from a sea urchin genomic clone containing part of a heat-shock protein 70 (Hsp70)-encoding gene. This fragment, named hsp70 gene II, contains 1271 bp of the flanking region and 3299 bp of structural gene sequence interrupted by five introns and encoding the N-terminal 371 amino acids (aa) of the protein. The 5' flanking region contains a putative TATA element, two CCAAT boxes, four heat-shock consensus sequence elements (hse) and one consensus sequence for binding of Sp1. Remarkable homologies were observed for deduced aa sequence and intron-exon organization between hsp70 gene II and rat hsc73 gene.
