Synthesis of habitat restoration impacts on young-of-the-year salmonids in boreal rivers

2019

River restoration offers the potential to enhance biological integrity, often measured as fish population changes. We used a meta-analytical approach to synthesize density responses to in-stream habitat restoration by young-of-the year (YOY) brown trout and Atlantic salmon in 28 rivers (overall 32 restoration projects) in Finland. We also examined which local and watershed-scale factors most influenced restoration success. Finally, we conducted an expert survey to obtain an independent estimate of a sufficient density enhancement for restoration to be considered successful. Despite strong context-dependency, habitat restoration had an overall positive effect on YOY salmonid density. When co…

Managing conservation values of protected sites: How to maintain deciduous trees in white-backed woodpecker territories

2020

Successional and other temporal habitat changes may also affect conservation areas and reduce their conservation value. Active management to promote vulnerable habitat features may be an effective, but controversial, solution. Old deciduous trees and deciduous dead wood in boreal forest reserves are examples of habitat features that may be lost during succession, yet several threatened species, including the white-backed woodpecker (Dendrocopos leucotos), are dependent on them. Encroaching spruce have been removed from white-backed woodpecker territories to promote the regeneration of deciduous trees and to preserve habitat quality, although the efficiency of this treatment is unclear. In t…

Análisis de la siniestralidad en ciclistas 2008-2013

2016

[ES] Los accidentes con víctimas ciclistas han sufrido un continuo ascenso en los últimos años. A fin de conocer cuáles son las características tanto del ciclista implicado en un accidente, como de las circunstancias en las que éste se ha producido, se ha realizado un estudio en el que se analiza la siniestralidad de los ciclistas registrada en España en el período comprendido entre 2008 a 2013. La investigación se ha realizado a partir de la base de datos de accidentes oficial de la Dirección General de Tráfico (base ARENA). En total se han analizado 25.439 accidentes con ciclistas implicados y 24.520 víctimas ciclistas. Los principales resultados de este estudio muestran que el número de …

“Pro-youthful” factors in the “labyrinth” of cardiac rejuvenation

2016

IF 3.350; International audience; The mechanisms of aging and senescence include various endogenous and exogenous factors. Among cardiovascular diseases, heart failure is a typical age-related disease. New strategies to restore cardiomyocyte cells have been reported: endogenous substances that can regenerate the heart's cardiomyocytes have been described: follistatin like 1 (FSTL1), growth-differentiation factor 11 (GDF11) and insulin-like growth factor 1 (IGF-I). Manipulation of the different anti and pro-pathways is essential to discover new approaches to regenerative therapies. (C) 2016 Elsevier Inc. All rights reserved.

Clinical Impact of Cystatin C/Cathepsin L and Follistatin/Activin A Systems in Breast Cancer Progression: A Preliminary Report.

2016

This study was directed to assess the clinical impact of the circulating cathepsin L, cystatin C, activin A, and follistatin in breast cancer patients. The serum concentrations of these molecules were determined by immunoenzymatic assays, and their association with some clinico-pathological parameters of breast cancer progression was evaluated. Our results identified cystatin C and activin A as predictive markers for the presence of breast cancer and bone metastasis, respectively. Therefore, these proteins may have a clinical role as circulating biomarkers in the diagnosis and therapeutic monitoring of breast cancer patients.

Ancient goat genomes reveal mosaic domestication in the Fertile Crescent

2018

How humans got their goatsLittle is known regarding the location and mode of the early domestication of animals such as goats for husbandry. To investigate the history of the goat, Dalyet al.sequenced mitochondrial and nuclear sequences from ancient specimens ranging from hundreds to thousands of years in age. Multiple wild populations contributed to the origin of modern goats during the Neolithic. Over time, one mitochondrial type spread and became dominant worldwide. However, at the whole-genome level, modern goat populations are a mix of goats from different sources and provide evidence for a multilocus process of domestication in the Near East. Furthermore, the patterns described suppor…

The grain market, short-term credit, and economic inequality in the Kingdom of Valencia. The towns of Cocentaina, and Castellón in the Fifteenth-Cent…

2018

Despite the predominance of small peasant farms in the Valencian countryside in the Late Middle Ages, large sections of the peasantry were forced to turn to the market to obtain cereals for consumption and sowing. Insufficient land and lack of liquidity caused by the seasonal cycle of crops made it necessary to use short-term credit, which was recorded in the court of local justice in the legal form of “obligacions”. The aim of this paper is to analyse the economic role of this credit market, identifying varieties of commercialised cereals, seasonality of purchases and payments, price trends and the socio-professional background of buyers (debtors) and sellers (creditors). Thus, we study ho…

Alongside in vivo models, a simpler and more mechanistic approach is required to study the effects of myostatin on skeletal muscle because myostatin is an important negative regulator of muscle size. In this study, myostatin was administered to murine (C2C12) and human (CHQ) myoblasts and myotubes. Canonical and noncanonical signaling downstream to myostatin, related ligands, and their receptor were analyzed. The effects of tumorkines were analyzed after coculture of C2C12 and colon cancer-C26 cells. The effects of myostatin on canonical and noncanonical signaling were strongly reduced in C2C12 cells after differentiation. This may be explained by increased follistatin, an endogenous blocke…

Children with Down syndrome in Finland and Italy: comparing adaptive behavior and services

2016

Objectives: The aim of this study was to compare a sample of Italian (n = 29) and Finnish children (n = 32) with Down syndrome for possible differences emerging from diverse educational surroundings. Besides the level of adaptive and challenging behaviors, some other issues were compared, including teacher satisfaction. Methods: We used the children’s teachers as informants. They were interviewed using standardized scales. Results: No differences in adaptive behavior or challenging behavior were observed between the samples. All children from the Italian sample were fully included in mainstream classes, while in the Finnish sample, 92% of all the school years were spent in self-contained sp…
