Chemical composition, in vitro digestibility and palatability of nine plant species for dromedary camels in the province of Semnan, Iran

This work studied the chemical composition of plants, and their digestibility and palatability to camels, selecting plants most eaten by camels from the Iranian desert of the province of Semnan. The results indicated that the order of usefulness, from the most useful, was: Salsola arbuscula, Seidlitzia rosmarinus, Suaeda fruticosa, Alhagi camelorum, Haloxylon ammodendron, Halostachys spp., Tamarix tetragyna, Tamarix stricta and Hammada salicornica. No correlation was detected between the organic matterdigestibility in dry matter and chemical composition, and there was no consistent relationship between either of these variables and palatability

Effect of plasmin and heparin on in vitro ovine spermoocyte interaction

This study was conducted to investigate the effect of plasmin and heparin on in vitro ovine spermoocyte interaction. Different concentrations of plasmin (0, 1, 10, 100 ng/ml) and heparin (0, 5, 10 IU/ml) were added alone or simultaneously into fertilization medium. After sperm and oocyte co-culture, binding and penetration of sperm to zona pellucida (ZP) were assayed. Treatment with 1 and 10 ng/ml plasmin resulted in higher sperm binding to ZP than those in control. The rates of sperm binding to ZP were increased with highest heparin concentrations (10 IU/ml). Heparin had no effect on penetration rate of sperm to ZP. Simultaneously effects of plasmin and heparin were not significant on penetration rate of sperm to ZP. But, 5 or 10 IU/ml heparin in the present of 1 ng/ml plasmin had higher effect on sperm binding to ZP than that in the other groups. These results suggest that plasmin and heparin (alone/simultaneously) might play a role in events related to fertilization in ovine

Influence of different levels of n-3 supplemented (fish oil) diet on performance, carcass quality and fat status in broilers

An experiment was conducted to evaluate fish oil as n-3 fatty acids source on some performance, carcass and serum parameters in broilers. One-day old Ross strain male broiler chickens (n = 120) were randomly arranged in four dietary treatments (0, 1.5, 3 and 4.5 percent fish oil), with three replicates for each treatment. Mean live weight and feed intake at the end of starting, growing and finishing periods in fourth treatment was lower than other treatments. All treatments containing fish oil significantlydecreased feed conversion ratio compared to control treatment. There were no significant differences on percent of carcass to live weight and abdominal fat percentage to carcass weight in T2, T3 and T4, but there were significant differences between control diet and the others. Serum triglycerides, cholesterol, LDL-c and VLDL-c concentrations were significantly reduced by fish oil treatments than the control diet, but serum HDL-c concentrations were significantly increased by using of diets containingfish oil. The results of this experiment indicated that dietary  supplementation of fish oil improved feed conversion ratio, carcass quality and HDL-c concentration in serum, but it decreased serum triglycerides, cholesterol, LDL-c and VLDL-c concentrations in serum of broiler chickens

The effectiveness of resilience training and stress management (SMART) on the quality of life in patients with thalassemia major

Background: Thalassemia is one of the most common genetic diseases in Iran with different physical and psychosocial consequences which affect these patients quality of life . Objectives: The purpose of this study was to investigate the effect of resilience training and stress management on the quality of life in patients with thalassemia major in Kerman-Iran. Methods: In this quasi-experimental study with pre-test and post-test design and a control group, 30 patients referred to Samen-al-Hojaj charity group, were selected by convenience sampling method and randomly divided into two experimental and control groups (each of 15 patients). After completing the pre-test, the experimental group received 10 sessions of training and stress management. Control group received no intervention. The data collection tool was the questionnaire of quality of life (SF-36). Data were analyzed by SPSS software using the covariance analysis. Results: The results of the covariance analysis in the studied variables indicate that the effect of the group (experimental intervention) on the post-test of physical function, general health, the role limitation for physical and emotional health were significant and respectively were (P=0.005 and F=11.22), (P=0.001 and F=16/02) and (P=0.049, F=4.3). However, the effect of the group on the post-test of role limitation for emotional reasons, physical pain, social function, and fatigue or vitality were not significant and respectively were (P=0.20 and F=1.741), (P=0.774 and F=0.085), (P=0.674 and F=0.183 ) and (P=0.288 and F=1.203). Conclusion: According to the results, based on the effectiveness of stress relief and management on some components of the quality of life in patients with thalassemia major, this study can be used to reach an effective solution to improve the quality of life and generally improve the mental status of patients

Spatial analysis of colorectal cancer in Iran

Colorectal cancer is one of the most common cancers. Due to demographic changes, it is predicted that the incidence of this cancer will increase. Variations of its incidence rate among geographical areas are due to various contributing factors. Since there have been a lack of studies on this topic in our country, the present assessment of spatial patterns of colorectal cancer incidence in Iran was performed. In this ecological study, the new cases of colon cancer were extracted from Cancer Registry Center report of the Health Deputy of Iran in 2009. The reported incidences of the disease were standardized on the basis of the World Health Organization population and the direct method. Then the data were inserted into the GIS software, and finally, using the analysis of hot spots (Getis-Ord Gi) high-risk areas were drawn. Provinces that are higher or lower than the national average (1.9 SD) were considered hot spots or cold spots, significant at the level of 0.05. A total of 6,210 cases of colorectal cancer were registered in Iran in 2009, of which 3,727 were in men and 2,783 in women (age-standardized rates of 11.3 and 10.9 per 100,000 population, respectively). The results showed that in central and northern Iran including Isfahan, Qom, Tehran, Qazvin and Mazandaran significant hot spots in men were present (p < 0.05). In women also we have high incidence in northern and central states: Mazandaran province (p < 0.01) and the province of Tehran (p < 0.05) had higher incidences than the national average and were apparent as significant hot spots. Analysis of the spatial distribution of colorectal cancer showed significant differences between different areas pointing to the necessity for further epidemiological studies into the etiology and early detection. © 2016, Asian Pacific Journal of Cancer Prevention

Incidence and mortality of colorectal cancer and relationships with the human development index across the world

Background: This study aimed to investigate the standardized incidence and mortality rate of colorectal cancer and its relationship with the human development index (HDI) across the world in 2012. Materials and Methods: This ecologic study was conducted for assessment of the correlation between age-specific incidence rate (ASIR) and age-specific mortality rate (ASMR) with HDI and its components. Data for SIR and SMR for every country for the year 2012 were obtained from the global cancer project. We used a bivariate method for assessment of the correlation between SIR and SMR and HDI. Statistical significance was assumed at P < 0.05. Statistical analyses were performed using SPSS (Version 22.0, SPSS Inc.). Results: Countries with the highest SIR of colorectal cancer in the world in 2012, were Republic of Korea, Slovakia, Hungary and countries with the highest SMR were Hungary, Croatia and Slovakia. The correlation between SIR of colorectal cancer and the HDI was 0.712 (P�0.001), with life expectancy at birth 0.513 (P�0.001), with mean years of schooling 0.641 (P�0.001) and with level of income per each person of the population 0.514 (P�0.013). In addition, the correlation between SMR of colorectal cancer and the HDI was 0.628 (P�0.001), with life expectancy at birth 0.469 (P�0.001), with mean years of schooling 0.592 (P�0.001) and with level of income per each person of the population 0.378 (P�0.013). Conclusions: The highest SIR and SMR of colorectal cancer was in the WHO Europe region. There was a positive correlation between HDI and SIR and SMR of colorectal cancer

Development of a synthetic gene network to modulate gene expression by mechanical forces

The majority of (mammalian) cells in our body are sensitive to mechanical forces, but little work has been done to develop assays to monitor mechanosensor activity. Furthermore, it is currently impossible to use mechanosensor activity to drive gene expression. To address these needs, we developed the first mammalian mechanosensitive synthetic gene network to monitor endothelial cell shear stress levels and directly modulate expression of an atheroprotective transcription factor by shear stress. The technique is highly modular, easily scalable and allows graded control of gene expression by mechanical stimuli in hard-to-transfect mammalian cells. We call this new approach mechanosyngenetics. To insert the gene network into a high proportion of cells, a hybrid transfection procedure was developed that involves electroporation, plasmids replication in mammalian cells, mammalian antibiotic selection, a second electroporation and gene network activation. This procedure takes 1 week and yielded over 60% of cells with a functional gene network. To test gene network functionality, we developed a flow setup that exposes cells to linearly increasing shear stress along the length of the flow channel floor. Activation of the gene network varied logarithmically as a function of shear stress magnitude

Automatic Prediction of Facial Trait Judgments: Appearance vs. Structural Models

Evaluating other individuals with respect to personality characteristics plays a crucial role in human relations and it is the focus of attention for research in diverse fields such as psychology and interactive computer systems. In psychology, face perception has been recognized as a key component of this evaluation system. Multiple studies suggest that observers use face information to infer personality characteristics. Interactive computer systems are trying to take advantage of these findings and apply them to increase the natural aspect of interaction and to improve the performance of interactive computer systems. Here, we experimentally test whether the automatic prediction of facial trait judgments (e.g. dominance) can be made by using the full appearance information of the face and whether a reduced representation of its structure is sufficient. We evaluate two separate approaches: a holistic representation model using the facial appearance information and a structural model constructed from the relations among facial salient points. State of the art machine learning methods are applied to a) derive a facial trait judgment model from training data and b) predict a facial trait value for any face. Furthermore, we address the issue of whether there are specific structural relations among facial points that predict perception of facial traits. Experimental results over a set of labeled data (9 different trait evaluations) and classification rules (4 rules) suggest that a) prediction of perception of facial traits is learnable by both holistic and structural approaches; b) the most reliable prediction of facial trait judgments is obtained by certain type of holistic descriptions of the face appearance; and c) for some traits such as attractiveness and extroversion, there are relationships between specific structural features and social perceptions
