Ecologia Balkanica , 2012,
Abstract: The present research examines the potentials and limitations of tourism in the Alamut region, offering suggestions and strategies for the promotion of tourism in this region. Research methodology adopted in this study is based on analytical-descriptive approach. To formulate and establish a sound research theoretical framework as well as to review the research literature, a questionnaire tooling method was used and the results were analyzed using the SWOT technique. While introducing the tourist attraction in the province, the influential factors in the region categorized into the four headings of: strengths; weaknesses; opportunities and threats were included in our considerations and strategies or guidelines for a sustained tourism development in the region provided. The research findings, taking into consideration the present status of the Alamut region, indicate that despite the fact that the region houses a great number of ancient sites and monuments and enjoys a high level of bio-diversity resources, making it the ideal candidate to be transformed into an exemplary tourist attraction pole, it is faced with major obstacles to reach this goal. In order to remove some of the problems of the region, strategic factors were analyzed and priorities delineated. The findings indicated that a focused attention and description of the values of the region is alleviated through the holdings of seminars or meeting and conferences as well as paving the way to give cultural knowledge and understanding to prevent inflicting widespread damages to the environment; to establish hotels; to provide welfare facilities and introduce natural resources as well as historical sites and their ancient heritage.

Abstract:

Oxidative damage and redox metal homeostasis loss are two contributing factors in brain aging and widely distributed neurodegenerative diseases. Oxidative species in company with excessive amounts of intracellular free iron result in Fenton-type reaction with subsequent production of highly reactive hydroxyl radicals which initiate peroxidation of biomolecules and further formation of non-degradable toxic pigments called lipofuscin that amasses in long-lived postmitotic cells such as neurons. Dietary flavonoid baicalein can counteract the detrimental consequences through exertion of a multiplicity of protective actions within the brain including direct ROS scavenging activity and iron chelation. In this study, we evaluated the neuroprotective effects of baicalein in menadione (superoxide radical generator)-treated SK-N-MC neuroblastoma cell line. Our results showed that treatment of cells with menadione led to lipofuscin formation due to elevated intracellular iron contents and accumulation of oxidative products such as MDA and PCO. Also, menadione caused apoptotic cell death in SK-N-MC cells. However, pretreatment with baicalein (40 μM) reversed the harmful effects by chelating free iron and preventing biomolecules peroxidations. Moreover, baicalein prevented cell death through modulation of key molecules in apoptotic pathways including suppression of Bax and caspase-9 activities and induction of bcl2 expression. Key structural features such as presence of hydroxyl groups and iron-binding motifs in baicalein make it the appropriate candidate in antioxidant-based therapy in age-related neurodegenerative diseases.

The Application of Prebiotics in Poultry Production
H. Hajati,M. Rezaei
International Journal of Poultry Science , 2010,
Abstract: For several decades, antibiotics and chemotherapeutics in prophylactic doses have been used in poultry diet to improve their welfare and to obtain economic benefits in terms of improved animal performance and reduced medication costs. With increasing concerns about antibiotic resistance, there is increasing interest in finding alternatives to antibiotics for poultry production. Prebiotics are one of the alternatives that can improve poultry performance through altering gut microflora. Furthermore, high protein prices and environmental concerns have pressured the industry to search for methods for reducing dietary protein levels.

Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2010.e19
Abstract: The effect of energy and protein dilution during 16 to 20 d of age, on performance, carcass characteristics and blood parameters of broiler chickens was studied in a completely randomized design with 3 treatments and 3 replicates in each treatment. A total of 144 mixed-sex chickens (Cobb 500) were randomly allocated to 9 pens. In order to dilute the diets three levels (0, 20 and 40%) of rice hull was used. During the experiment feed intake, body weight gain, feed conversion ratio were measured weekly. The results indicated that dilution of diet from 16 to 20 d of age increased feed intake in this period, but adjusted feed intake (excluded rice hull) was decreased (P<0.05). Restricted bird consumed more feed in the whole period of the experiment (16 to 44 d). With increasing dilution rate during restriction period, body weight gain of chickens decreased in comparison to control group (P<0.05). Due to compensatory growth after restriction period, restricted chickens had higher body weight gain than control groups at 44 d of age. Feed dilution up to 20 percent had not significant effect on feed conversion ratio in the whole period of the experiment. Diet dilution had not significant effect on carcass, breast meat, legs, proventriculus, heart and feet weight proportion. Diet dilution significantly increased gizzard weight proportion, and decreased abdominal fat pad weight, carcass crude fat, and increased carcass crude protein proportion (P<0.05). Feed dilution up to 20% increased HDL and decreased LDL concentration in plasma at 21 d of age. Diet dilution up to 40% decreased the concentrations of cholesterol, triglyceride, plasma T3, and increased the concentrations of uric acid and plasma T4 at 21 d of age (P<0.05). Diet dilution up to 20 percent increased plasma glucose concentration at 42 d of age (P<0.05). The results of the present study indicated that feed dilution with 20% rice hull during 16 to 20 d of age had not adverse effect on broiler performance and it also reduced abdominal fat pad weight and carcass crude fat proportion.

Abstract: The purpose of this paper is to examine the role of women in urban management and possibility of a more inclusionary approach to their active participation. Here, first the underlying concepts and principles of good urban governance and special needs of women in urban settings are discussed; next capabilities of Iranian women for active participation in good urban governance are examined. The study shows that women are in utter need to be empowered and to take more active role in their urban lives. Also it shows that Iranian women have used the means available to them to improve their capabilities. It also shows that there are needs for further research to better understand the socio-cultural obstacles to higher participation rate of women in governance. The paper is an original investigation of Iranian women's attempt to improve their lives through the available means to them within a paternalistic society. It shows their success and failures and draws future directions of their latent movement. Keywords: Urban governance, Empowerment, Women, Iran
Spectroscopy of Masses and Couplings during Inflation

Physics , 2013, DOI: 10.1088/1475-7516/2014/04/031
Abstract: In this work, we extend the idea of Quasi Single Field inflation to the case of multiple isocurvaton fields with masses of order of Hubble, which are coupled kinetically to the inflaton field and have some interactions among themselves. We consider the effects of these massive modes in both the size and the shape of the bispectrum. We show that the shape of the bispectrum in the squeezed limit is dominated by the lightest field and is the same as in Quasi Single Field inflation. This is a generic feature of multiple isocurvaton fields and is independent of the details of the interactions among the massive fields. When the isocurvaton fields have similar masses, we can potentially distinguish two different shapes in the squeezed limit so that the shape of the bispectrum can act as a particle detector. However, in the presence of hierarchy among the massive fields, the dominant effect is due to the lightest field.
Non-equilibrium steady state in the hydro regime

Physics , 2015,
Abstract: We study the existence and properties of the non-equilibrium steady state which arises by putting two copies of systems at different temperatures into a thermal contact. We solve the problem for the relativistic systems that are described by the energy-momentum of a perfect hydro with general equation of state (EOS). In particular, we examine several simple examples: a hydro with a linear EOS, a holographic CFT perturbed by a relevant operator and a barotropic fluid, i.e., P = P(E). Our studies suggest that the formation of steady state is a universal result of the hydro regime regardless of the kind of fluid.

Abstract: Lipofuscin-like pigments (LFPs) are highly oxidized cross-linked aggregates of oxidized protein and lipids which are formed under oxidative state conditions by free radicals produced. The present study aimed to evaluate the probable ameliorative effects of some of the Mn-salens namely EUKs 8, 134, 15, 115, 122 and 132 (compounds 1-6) and vitamin C against carbon tetrachloride (CCl4)-induced acute damage on rats’ livers and brains. Exposure to CCl4 is believed to induce oxidative stress and cause tissue damage due to the formation of trichloromethyl (·CCl3) and peroxy trichloromethyl (·OOCCl3) radicals. In this study, 54 rats were randomly divided into 9 groups of six each: normal group received only vehicle (olive oil; 2 ml/kg b.w.) for 6 consecutive days; CCl4- intoxicated group received the vehicle and CCl4 (50% solution of CCl4 in olive oil, 2 ml/kg b.w.) on the first and second days and the vehicle on the third to sixth days; test rats received Mn-salens or vitamin C (20 mg/kg b.w.) and CCl4 (2 ml/kg b.w.) on the first and second days and Mn-salens or vitamin C (20 mg/kg b.w.) on the third to sixth days. Mn-salens administration ameliorated the effects of CCl4 by decreasing the levels of ROS, lipid and protein oxidations and LFPs formation on liver and brain as well as cholesterol and triglycerides, aminotransferases and alkaline phosphatase contents in sera of rats whereas increased the activities of catalase, superoxide dismutase,glutathione reductase, glutathione peroxidase and reduced glutathione in liver and brain tissues. Histopathological studies confirmed the toxic effects of CCl4 and ameliorative action of Mn-salens on tissues. These results suggest that the evaluated EUKs were able to attenuate LFPs accumulation and morphological changes caused by CCl4 in rats and thus, confirming the ameliorative role of Mn-salens against CCl4-induced oxidative damage and age-related diseases.

Abstract:
Oxidative stress has been implicated to play a crucial role in the pathogenesis of Alzheimer’s disease (AD). Currently, it is known that numerous signaling pathways involved in neurodegenerative disorders are activated in response to oxidative stress. Recent directions on AD treatments have focused on the use of antioxidants including Curcumin, a hydrophobic polyphenol derived from the rhizome of the herb Curcuma longa, to augment the intracellular antioxidant defences. In the present study, hydrogen peroxide (H2O2) was used to evaluate the effects of oxidative stress on apoptotic SK-N-MC cells death with focus on changes in activity of Notch signaling pathway. The extent of lipid peroxidation, protein oxidation and intracellular ROS (Reactive Oxygen Species) levels was investigated as oxidative stress biomarkers. Here, we showed that H2O2 reduced GSH levels and activity of antioxidant enzymes and also influenced Notch signaling activation. The present data concluded that Curcumin protected cells against oxidative stress-induced apoptosis.
