Prolidase in the Marine Sponge Suberites domuncula: Enzyme Activity, Molecular Cloning, and Phylogenetic Relationship

1999

: The enzyme prolidase hydrolyzes the peptide bond that involves the imino nitrogen of proline or hydroxyproline; hence, it catalyzes the final step in collagen degradation. From mammals it is known that this enzyme plays a major role in the recycling of proline for collagen synthesis and can be considered to be essential for the control of cell growth. The dominant organic exoskeleton in sponges, especially in Demospongiae, is collagen and the collagen-related spongin. Here we demonstrate that crude extracts of the demosponge Suberites domuncula contain prolidase or prolidase-like activity. The complementary DNA encoding the putative prolidase was cloned from a library of the same animal. …

Growth patterns of the topshell Phorcus lineatus (da Costa, 1778) in northern Iberia deduced from shell sclerochronology

2019

Combined shell growth pattern and oxygen isotope analysis has become a powerful approach in palaeoclimate and archaeological studies for reconstructing palaeoclimate conditions and littoral exploitation patterns, respectively. Recent investigations have shown that the gastropod Phorcus lineatus (da Costa, 1778) forms its shell in conditions of near equilibrium with the oxygen isotope signature of the seawater environment, demonstrating the utility of this species for reconstruction of sea surface temperature and determination of the season of harvest in archaeological studies. In contrast, the shell growth patterns of this species have received virtually no attention despite providing infor…

In-Between ‘Smart’ Urban Growth and ‘Sluggish’ Rural Development? Reframing Population Dynamics in Greece, 1940–2019

2020

Multifaceted demographic dynamics have shaped population growth in Mediterranean Europe, reflecting a metropolitan cycle from urbanization to re-urbanization. To assess the distinctive impact of economic downturns on population dynamics, the present study illustrates the results of an exploratory analysis that assesses urban expansion and rural decline at various temporal scales in Greece, a peripheral country in southeastern Europe. Statistical analysis based on multivariate exploratory techniques outlined the persistent increase of regional populations, evidencing the distinctive role of agglomeration/scale with urbanization and early suburbanization phases (1940&ndash

Carbohydrate metabolism of vegetative and reproductive sinks in the late-maturing peach cultivar ‘Encore’

1999

Activities of NAD(+)-dependent sorbitol dehydrogenase (SDH), sorbitol oxidase (SOX), sucrose synthase (SS), acid invertase (AI), and neutral invertase (NI) in 'Encore' peach (Prunus persica L.) fruits and developing shoot tips were assayed during the growing season to determine whether carbohydrate metabolizing enzymes could serve as indicators of sink strength. In fruit flesh, SS activity was detected during Stage I of growth, when cells were actively dividing, and SDH activity was detected during Stage III, when cells were actively enlarging. Acid invertase activity was detected during Stage I and showed a closer correlation with relative increase in fruit weight during the growing season…

Cryopreservation of white mulberry (Morus alba L.) by encapsulation-dehydration and vitrification

2011

Shoot apices of in vitro-grown plantlets of white mulberry, Morus alba L. cv Florio, were cryopreserved using either encapsulation-dehydration or vitrification. For encapsulation-dehydration, alginate beads containing apices were dehydrated for 1, 3, 5 or 7 days in a liquid medium containing various sucrose concentrations (0.5, 0.75, 1.0 or 1.25 M). Bead desiccation was performed using silica gel for either 0, 4, 6, 8, 9 or 14 h. For vitrification, apices were directly immersed for either 5, 15, 30 or 60 min in a vitrification solution (PVS2). Following encapsulation-dehydration, treatment of alginate beads with 0.75 M sucrose was more effective in promoting re-growth of explants after imme…

Noninvasive Flap Preconditioning by Foam-Mediated External Suction Improves the Survival of Fasciocutaneous Axial-Pattern Flaps in a Type 2 Diabetic …

2018

Background Advances in reconstructive surgery are leading to an increased number of flaps at risk for ischemic necrosis, because of either intrinsic (e.g., larger flap size) or extrinsic (e.g., diabetes) factors. Methods to preoperatively improve flap vascularity and limit postoperative ischemia are lacking. Noninvasive suction, using either a macrodeformational silicone cup interface (external volume expansion) or a microdeformational polyurethane foam interface (foam-mediated external volume expansion), has been shown to induce angiogenesis in tissues. The authors investigated whether the preoperative use of external volume expansion/foam-mediated external volume expansion improves flap s…

External Volume Expansion Increases Subcutaneous Thickness, Cell Proliferation, and Vascular Remodeling in a Murine Model

2012

Background Fat grafting is a powerful tool for soft-tissue reconstruction; however, the science behind recipient bed preparation has not been thoroughly explored. External volume expansion using suction before fat grafting has been used clinically to improve reliability and consistency of graft survival. The authors developed a murine model to investigate the underlying mechanism of external volume expansion. Methods The authors created an external volume expansion device using a soft-silicone dome connected to a vacuum source (25 mmHg) to treat the dorsum of mice, and the response was compared with treatment with an occlusive dressing. Treated areas were monitored with magnetic resonance i…

General Consideration of the Agricultural Holding in Arges County

2013

Abstract This paper aims to present the state farms and agricultural area used by those in the county of Arges and Sud-Muntenia region according to legal personality, based on the latest statistics. In this paper we address the size of agricultural holdings in terms of physical size, agricultural area (UAA) in number of hectares, by type of animal that you own and the number of farms.In the analyzed period shows that the agricultural sector in Romania individual continues to be the main component of Romanian private farming, which consists of individual farms and family associations without legal personality disorder. The data indicates that we are dealing with a decrease in average 5% from…

Kasvun tekijät : tutkimus Suomen teollistumisen ajan perustajayrittäjistä 1870-1990

2017

Company founders are important agents in business economics. I investigated entrepreneurs who founded successful, long-standing and high-growth companies. The data include 402 Finnish founder entrepreneurs who had founded a company and had been awarded the Finnish title of neuvos during the period 1917-2015 (i.e., since the beginning of Finnish independence). So far only few longitudinal studies have been presented on company founders in Finland. This study focuses on the era of industrialism in Finland and addresses the following research questions. First, what kind of entrepreneur groups are identified in different phases of industrialism when studying the backgrounds, education and work …
