Short- and long-term growth responses to drought and climatic influences still remain poorly understood. In this study, we investigated the impact of climatic drivers (temperature, precipitation) and drought, using the Standardized Precipitation Index (SPI) calculated at different time scales (1-48 months), on earlywood (EW) and latewood (LW) widths in Pinus halepensis. Nine forests subjected to dry summer conditions were sampled in Mediterranean semi-arid areas from north-eastern Spain. In addition, we explored the seasonal dynamics of cambial activity and wood formation in relation to short-term climate variability. We found two peaks of tracheid cell production corresponding to EW (May-June) and LW (mid-July-August) growth phases, associated with a sharp decrease in enlarging cells in early July in response to low water availability. In the period of analysis (1970-2005), EW growth was positively correlated with precipitation in previous December and current January, April, May and June, while it was negatively correlated with temperature in June and July. LW was correlated positively with minimum temperatures in January. Probably this was an indirect relationship as a consequence of increased EW width at higher January temperatures. Drought affected more negatively EW than LW formation as evidenced the higher SPI-EW correlation (r = 0. 72) than the SPI-LW one (r = 0. 54). The strongest EW response to drought was observed in July, whereas the highest LW response to drought occurred in September; and this seasonal pattern matched the phases of lowest EW and LW tracheid production. Under a future reduction of winter and spring precipitation, the studied forests may show a decrease in tracheid cell production, causing a decline of radial growth, a reduction in hydraulic conductivity and, indirectly, a hampered carbon uptake in such semi-arid woodlands. © 2012 Springer-Verlag.

Isoform 2 of calsequestrin (CASQ2) is the main calcium-binding protein of sarcoplasmic reticulum (SR), expressed both in cardiac and in skeletal muscles. CASQ2 acts as an SR calcium (Ca2+) sensor and regulates SR Ca2+ release via interactions with triadin, junctin, and the ryanodine receptor. Various mutations of the csq2 gene lead to altered Ca2+ release and contractile dysfunction contributing to the development of arrhythmias and sudden cardiac death in young individuals affected by catecholaminergic polymorphic ventricular tachycardia (CPVT). Recently, a transgenic mouse carrying one of the identified CASQ2 point-mutations (R33Q) associated to CPVT was developed and a drastic reduction of the mutated protein was observed. Following a biomolecular approach, several analysis were performed using different antibody treatments in order to identify when the reduction of CASQ2 begins in skeletal muscles, unveil the mechanism involved in the reduction of CASQ2 in slow-twitch and fast twitch muscles and verify if other proteins are affected by the presence of the mutated protein. Mutated CASQ2 decreased soon after birth. Up-regulation of proteins associated to the unfolded protein response (UPR) was also observed. Important proteins in skeletal muscle triads formation were analyzed and increased protein levels were observed in adult knock-in CASQ2-R33Q/R33Q mice. Probably, R33Q mutation induced the decrease of CASQ2 by activation of the UPR and subsequently degradation through proteasome. © Acta Facultatis Medicae Naissensis 2015. Source

Protected areas (PAs) provide some important goods and services, thus making them an important contributor to social well-being. They are widely regarded as the cornerstones of biodiversity conservation strategies worlwide, providing the main foundation for in situ conservation of flora and fauna, being an important element of any sustainable development. The double impacts of climate change and biodiversity loss are major threats to achieving the Millennium Development Goals, especially those relating to environmental sustainability, poverty alleviation and food and water security. Protected undeveloped areas are an important tool for land conservation in developing nations. Efficient land allocation decisions and resource management requires knowledge of non-market benefits. The contingent valuation method is a stated preference method of non-market valuation where respondents are asked to state their preferences for an environmental good or service that is not bought and sold in traditional markets. This study used contingent valuation method (CVM) to derive estimates of economic value for recreational benefits use of Albanian part of Prespa Park (AL-Prespa), in southeastern Albania. The contingent valuation survey used a dichotomous choice (DC) format followed by an openended question asking for their maximum WTP for restoration. Park visitors were surveyed regarding their willingness-to-pay (WTP) for ecological restoration and recreational benefits of area. The WTP responses were analysed using a probit procedure. The results of the study indicated that visitors are willing to pay increased entrance fees to finance ecological restoration and recreational benefits of areas damaged by human activities. Consumer surplus for ecological restoration and recreational benefits of the AL-Prespa elicited through the close-ended DC exercise was found to be € 1.4 per person, and elicited through the open-ended exercise was found to be about € 1.6. The factors and personal characteristics of the visitors that affect respondent’s WTP for ecological restoration and recreational benefits damaged by human activities in AL-Prespa could be important inputs in order to ensure successful environment protection. The results of this study also should be helpful to assist the authority for the fee system and how much they can increase the new entrance fee charged to the visitors. © 2014 World Food Ltd. and WFL Publishers.

This paper emphasizes the vital importance of the agriculture sector to the food security for Albania and other neighboring post-communist countries. The aim of this study is to illustrate how investments in agricultural development and food security can protect these countries form future global crisis. Agriculture sector used to be a major contributor to the Albanian economy until the 90’s and its role decreased with the liberalization of the economy. Albanians are of the opinion that more investment opportunities within the agricultural sector are required to decrease poverty at the national level and to make sustainable development possible for Albania. To achieve this, agricultural development and food security must be at the focus of the Albanian economy. This paper recommends an increase in investment within the agricultural sector across the nation. The mixed research approach method was used to validate these claims. © 2013, Econjournals.

Calreticulin (CRT) is a low molecular weight protein present in vertebrates, invertebrates and higher plants. Its multiple functions have been demonstrated. It plays an important role as a chaperone and Ca2+ buffer inside sarcoplasmic/endoplasmic reticulum (SR/ER), and outside the ER in many physiological/pathological processes. Recently it has been observed that CRT over-expression or its absence is linked to various pathological conditions, such as malignant evolution and progression, and these facts really increased its study interests. Using an evolution approach CRT was further characterized. Several Bayesian phylogenetic analyses were performed using coding and amino acid sequences. CRT molecular evolution was investigated for the presence of negative or/and positive selection using HyPhy package. The results indicated that the purifying selection might have operated over the whole CRT primary structure. Although, an episodic diversifying selection was also found on the analyzed CRT sequences. © 2013 Institute of Molecular Biology, Slovak Academy of Sciences. Source
