Irisin, a novel peptide, was initially been shown to be expressed explicitly in the muscle tissues. We studied the presence of irisin immunoreactivity in porcupine adrenal glands and kidneys. Immunocytochemistry showed that irisin was localised both in the adrenal cortex and adrenal medulla. In organs, irisin immunoreactivity was found in the tubular and collecting system of the nephron. The functional role of irisin in the adrenal gland and kidney has not been precisely yet. However, irisin might have a paracrine and autocrine function as do other locally produced peptides. 相似文献

The aim of the present research was to investigate the fruit quality of twenty different local pear varieties (Pyrus communis L.), namely Ahlat, Ankara, Arpa, B?ld?rc?n, Çermai, Cinci, Gelin Bo?an, Hac? Hamza, Hah?r, Kabak, K?z?l, Kokulu, Mehrani, Menendi, Sulu, ?algam, Tokat Sultan?, Tur?u, Yaz, and Yaz Meyri?i, grown in Gumushane province in terms of pomological and morphological characteristics and chemical compositions. The fruit mass, fruit width and length, fruit stem thickness and length, fruit kernel width and length, hardness of pulp, number of seeds, leaf width and length, leaf stem length and thickness, and water soluble dry matter (WSDM) of the pear fruits have been determined as pomological and morphological characteristics. On the other hand, the chemical compositions of the pear varieties have been evaluated in terms of protein, ash, sucrose, fructose, glucose, total sugar, titratable acidity, moisture, and mineral element levels.Both pomological and morphological results demonstrated that the local pear varieties are important in terms of rehabilitation studies and detailed selection studies on these local varieties should be performed. The chemical analyses result of the pear varieties revealed that there is no component that may be harmful to human health when consumed, and also these varieties contains the necessary amount of mineral elements. 相似文献

This study was carried out in Arsin (Trabzon/Turkey) in 2011. The effects of different harvest time and altitudes on the quality of the nuts have been investigated. The study was performed on Fo?a hazelnut and the harvest process has been conducted at three terms, which are on normal harvest time and ten days before and after harvest time. The harvested nuts were dried in the shade on the concrete floor until their moisture content decreased to 5?%. Some properties of nuts including yield, fruit weight, internal weight, shell thickness, and protein, oleic, and linoleic acid amounts have been investigated. As evaluated all of the fruit properties it can be concluded that 11 August is the most suitable harvest date for coast zone. On the other hand, no significant differences were obtained in the point of protein, oleic, and linoleic acid amounts for different harvest time and altitudes. 相似文献

Thirty one pears genotypes from east blacksea region were evaluated for genetic relationships by using Randomly Amplified Polymorphic DNA (RAPD) and ISSR (Inter-Simple Sequence Repeats) markers from total 70 RAPD and ISSR primer investigated, 22 could amplify clearly and consistently. Cluster analysis of the pears genotypes was performed based on data from polymorphic bands RAPD and ISSR by using Jaccard’s similarity coefficient and the Unweighted pair-group method with arithmetic average (UPGMA) clustering method. The 31 pear genotypes were classified into two major groups. Cluster A was divided into 2 subclusters: Gumushane pears and Trabzon pears. Cluster B consisted of Artvin pears. The similarity matrix values ranged between 0.105 and 0.968. 相似文献

Phthalates such as di‐n‐butyl phthalate (DBP) and their esters are widely used plasticizers, their ubiquitous presence in daily life, inevitably leads to their restricted use due to important environmental pollution and health impacts and endocrine disruption potential. The aim of this study was to examine the effects of a sublethal concentration of 10 mg L?1 DBP on haematocrit (HCT) values, gills and liver histology, malondialdehyde (MDA, 2‐thiobarbituric acid‐TBA reactivity) and reduced glutathione (GSH) levels in gills and liver tissue as oxidative stress biomarkers in the aquaculture fish species Nile tilapia (Oreochromis niloticus) after 24 (DBP‐24) and 96 (DBP‐96) h exposure. No differences were found between per cent HCT values in the 24 h exposure groups (P > 0.05). Response of antioxidant defence systems in liver and gill tissues of the fish were dependent on exposure duration and changed to a higher extent during 96 h. MDA levels in liver tissue increased in DBP treated fish in comparison to the control fish. However, the differences between the exposure and control groups were not significant (P > 0.05). A statistically significant decrease (P > 0.05) was recorded in gill MDA levels in the DBP‐96 group when compared to the control and DBP‐24 groups. The liver GSH levels were unchanged in the DBP treated fish. However, GSH levels were significantly lower in the gill tissue of the DBP‐96 group. Exposure to DBP caused several degenerative changes in the histology of gill and liver tissue. Gills displayed hyperaemia, epithelial lifting, oedema, talengiectasia, epithelial hyperplasia and fusion of secondary lamellae, whereas in liver several circulatory anomalies (hyperaemia, blood congestion and sinosoid dilatation) and vacuolization of hepatocytes were observed. Histopathological results demonstrated that the gills were more affected than the liver perhaps due to their direct contact with DBP. 相似文献

A tire is a composite of rubber and reinforcing materials. Polymeric materials used as reinforcing components are usually
synthetic yarns. These synthetic yarns have high tenacity, they are made of continuous multifilaments. The yarns are converted
in the cord form to provide desired mechanical, thermal and adhesion properties by a series of conversion processes. Besides
of multifilament synthetic cords, there are some specific areas in which single ply monofilament cords have been utilized
as a reinforcing element. In this study, new cord structures have been developed by using monofilament yarns and by imitating
multifilament cords. New cord structures exhibited some very interesting cord properties compared to both single ply monofilament
cord and multifilament cords. Monofilament yarns having diameter between 0.23 and 0.50 mm have been twisted together from
3 to 6 plies based on mixed Taguchi model to form cords. Nylon 6.6 and Polyester monofilament yarns have been selected because
of common application of their multifilament counterpart yarns in tire carcass and capply. The twisted monofilament cords
have been adhesive treated to produce cords ready to adhere rubber. The mechanical properties, thermal stability, adhesion
with rubber, fatigue properties under dynamic conditions, retention of properties after curing and microscopic analysis of
the cords have been analyzed. The cords have been found to possess some benefits for tire carcass, breaker, belt and belt
protective layer applications with their superior fatigue performance, cut resistance, stiffness, ligth weigth etc. 相似文献

We studied with quantitative and microscopical methods the heart of rats divided into five age groups: embryos at the age of 11 days, fetuses at the age of 16 days and 20 days and also heart samples of 3-day-old pups and young adults (5 weeks of age) were used (n = 10 samples in each group). At the end of the study; heart samples were obtained from all animals. Stereological estimations were performed on heart volume, volume of heart lumen (ventricles and atria), volume of myocardium, numerical density of the myocyte nuclei and mean nuclear diameter of myocytes. Volumetric values and numerical data were estimated via Cavalieri method and physical dissector, respectively. In this study, histological examination was performed at light and electron microscopic levels. The numerical density of the myocyte nuclei increased from fetuses to young adults. Differences between embryos and fetuses, between fetuses and 3-day-old pups, and between 3-day-old pups and young adults were statistically significant. These results indicate that myogenesis continued in the rat myocardium during prenatal life and after birth. 相似文献

Total anthocyanins were extracted from eleven sweet cherry cultivars grown in Sakarya, Turkey. In vitro inhibition effects of extracted total anthocyanins on purified carbonic anhydrase I and II were investigated by using CO2 as a substrate. The results showed that all extracted total anthocyanins inhibited the hCA I and hCA II enzyme activities. Among all cultivars, ‘Merton Premier’ was found to be the most active one against both hCA I (IC50?=?0.83?µg/mL) and hCA II (IC50?=?1.16?µg/mL). Additionally, the DPPH activities of the extracts were investigated as antioxidant properties. The results exhibited that ‘Churchill’ and ‘Merton Premier’ have high antioxidant activity with 74.102% and 73.503% DPPH activity, respectively.
