1599

Teoloģiski, filozofiski ētisks un vēsturisks traktāts, viens no apjomīgākajiem N. Molllīna iespieddarbiem. Izdots arī latīņu valodā (1588, 1599). Vācu valodas izdevums dāvāts Livonijas karavadonim dažādu valstu karadienestā Georgam Fārensbaham (1551-1602), Cēsu pirmajam vaivadam no 1598. gada līdz 1602. gadam, kad krita karā pret zviedriem aplencot Vīlandes pili. Grāmatas titullapu ietver ornamentāla aproce ar dažādām fantastiskām būtnēm, grifiem, jūras vāravām utml. Ievadā publicēta Dāvida Hilhena vēstule Georgam Cīgleram. Tad seko Dāniela Hermaņa sacerētais Georga Fārensbaha dzīves apraksts. Šis G. Cīglera darbs ir vienīgais Mollīna iespieddarbs, kas guvis plašāku ievērību ārpus Livonijas…

Phylogenetic position of two Macrobiotus species with a revisional note on Macrobiotus sottilei Pilato, Kiosya, Lisi & Sabella, 2012 (Tardigr…

2021

In a moss and lichen sample collected on the Polish coast, a new population of Macrobiotus sottilei was found. Given that the original description of M. sottilei was based solely on the morphology observed under light microscopy and measurements of a few individuals, we provide, by means of integrative taxonomy, a revisional note on this species. We present a comprehensive set of morphometric and morphological data from light and scanning electron microscopy analysis together with nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) DNA fragments. We also provide the same set of DNA sequences for Macrobiotus glebkai from a population recently found i…

Catching-up to foreign technology? Evidence on the “Veblen–Gerschenkron” effect of foreign investments

2006

Abstract The presence of foreign multinational enterprises may benefit local economies. In particular, highly productive foreign-owned firms may promote the technological catch-up of local firms. This channel of spillovers is defined as the “Veblen–Gerschenkron” effect of foreign direct investment and is analyzed in this article. Rather than the overall concentration of foreign-owned plants in a region or sector, it is their productivity advantage that determines the positive effect on domestic firms in geographical and technological proximity. We test this hypothesis using new firm-level data for German and Italian manufacturing firms during the 1990s. These two countries are particularly …

Treatment with soluble activin type IIB-receptor improves bone mass and strength in a mouse model of Duchenne muscular dystrophy.

2016

Background Inhibition of activin/myostatin pathway has emerged as a novel approach to increase muscle mass and bone strength. Duchenne muscular dystrophy (DMD) is a neuromuscular disorder that leads to progressive muscle degeneration and also high incidence of fractures. The aim of our study was to test whether inhibition of activin receptor IIB ligands with or without exercise could improve bone strength in the mdx mouse model for DMD. Methods Thirty-two mdx mice were divided to running and non-running groups and to receive either PBS control or soluble activin type IIB-receptor (ActRIIB-Fc) once weekly for 7 weeks. Results Treatment of mdx mice with ActRIIB-Fc resulted in significantly in…

Altered tachykinergic influence on gastric mechanical activity in mdx mice

2006

Abstract This study investigated whether alterationsin gastric activity in dystrophic mdx mouse can beattributed to dysfunctions of tachykinins. Endolumi-nal pressure was recorded and the expression ofneuronal nitric oxide synthase (nNOS), NK1 and NK2neurokinin receptors was investigated by immunoh-istochemistry. SR48968, NK2 receptor antagonist, butnot SR140333, NK1 receptor antagonist, decreased thetone only in mdx gastric preparations. In the presenceof N x -nitro- L -arginine methyl ester ( L -NAME), inhib-itor of NOS, SR48968 reduced the tone also in normalstomach. [Sar 9 , Met(O 2 ) 11 ]-SP, agonist of NK1 recep-tors, caused tetrodotoxin-sensitive relaxations, antag-onized by SR140333…

Exploration of lipid metabolism in relation with plasma membrane properties of Duchenne muscular dystrophy cells: influence of L-carnitine.

2012

Duchenne muscular dystrophy (DMD) arises as a consequence of mutations in the dystrophin gene. Dystrophin is a membrane-spanning protein that connects the cytoskeleton and the basal lamina. The most distinctive features of DMD are a progressive muscular dystrophy, a myofiber degeneration with fibrosis and metabolic alterations such as fatty infiltration, however, little is known on lipid metabolism changes arising in Duchenne patient cells. Our goal was to identify metabolic changes occurring in Duchenne patient cells especially in terms of L-carnitine homeostasis, fatty acid metabolism both at the mitochondrial and peroxisomal level and the consequences on the membrane structure and functi…

Absence of an aging-related increase in fiber type grouping in athletes and non-athletes

2020

The ageing-related loss of muscle mass is thought to be partly attributable to motor neuron loss and motor unit remodelling that result in fibre type grouping. We examined fibre type grouping in 19- to 85-year-old athletes and non-athletes and evaluated to which extent any observed grouping is explained by the fibre type composition of the muscle. Since regular physical activity may stimulate reinnervation, we hypothesised that fibre groups are larger in master athletes than in age-matched non-athletes. Fibre type grouping was assessed in m. vastus lateralis biopsies from 22 young (19-27 years) and 35 healthy older (66-82 years) non-athletes, and 14 young (20-29 years), 51 middle-aged (38%6…
