The aim of this study was to investigate the anatomy of the arterial supply and branches of the thoracic limb of the porcupine. With this aim, five (three male and two female) adult porcupines were used. The vascular tree of the thoracic limb was injected through the common carotid arteries with coloured latex. The a. thoracica externa arose from the a. axillaris at the level of the fourth rib. It divided into two branches and went to the m. cutaneus trunci and the m. pectoralis ascendens. The a. subscapularis came off the a. thoracodorsalis. Later, the a. circumflexa humeri caudalis et cranialis, the three muscular branches and the a. circumflexa scapulae arose from the a. subscapularis. The a. profunda brachii arose together with the a. bicipitalis from the same truncus. The a. collateralis ulnaris left from the a. brachialis independently. Rete carpi dorsale was formed by the a. radialis. the r. carpeus dorsalis of the a. collateralis ulnaris and the a. interossea caudalis. Arcus palmaris profundus was formed by the r. profundus of the a. interossea caudalis and the r. palmaris profundus of the a. radialis. In conclusion, despite a partial resemblance to that in the rat, the distribution of the thoracic limb arteries in the porcupine was found to be completely different from that of other mammals. These findings represent, to our knowledge, the first study on the distribution of thoracic limb arteries in the porcupine. 相似文献

The aim of this study was to determine models which will be used for the estimation of adult live weights based on some body measurements using multiple regression model in Karya sheep of different age groups. Animal material of the study consisted of a total of 215 Karya sheep. Least squares means for live weight, body length, rump height, withers height, back height, chest depth, chest girth, and chest width of Karya sheep in Adnan Menderes University Group Sheep Breeding Program elite flock and breeder flocks were found as 47.24 kg, 67.08, 68.29, 68.58, 66.97, 30.04, 93.24, and 18.29 cm, respectively. Karya ewes were put into five categories according to ages (2–6 years). High positive phenotypic correlation coefficients were observed between live weight and body measurements of animals in different age groups (2–6 years). Among the formed multiple regression models, the highest coefficients of determination (R 2) were obtained from the models formed for body length or body length and chest girth together (R 2?=?0.79, R 2?=?0.87). It is concluded that live weight of Karya sheep can be estimated with a high accuracy using some body measurements and statistical methods. 相似文献

In this study, p-tert-butylcalix[4]-aza-crown (CAC) immobilized sporopollenin (Sp) was used as a sorbent for the removal of Cu(II), Pb(II) and Zn(II) from aqueous media. Sporopollenin was firstly functionalized with 3-chloropropyltrimethoxysilane (CPTS) in order to obtain chloro-sporopollenin (Sp-Cl). The Sp-Cl was reacted subsequently with CAC yielding CAC-bonded sporopollenin (Sp-Cl-CAC). The new sorbent was characterized by infrared spectroscopy (FTIR), thermal analysis (TG/DTG) and scanning electron microscopy (SEM). The sorption properties of modified sorbent (Sp-Cl-CAC) are also investigated. The optimum pH values for the separation of metal ions from aqueous solution onto Sp-Cl-CAC were 5.0 for Pb(II) and Cu(II) and 5.5 for Zn(II). The maximum sorption capacities for Cu(II), Pb(II) and Zn(II) were 0.07 (4.44?mg?g?1), 0.07 (4.58?mg?g?1) and 0.14 (29.00?mg?g?1) mmol?g?1, respectively. Sorption thermodynamic parameters of such as free energy (?G o), enthalpy (?H o), and entropy (?S o) were evaluated. 相似文献

Tei index (myocardial performance) and cardiac biomarkers were evaluated in dogs with parvoviral enteritis (PVE). Tei index was calculated as isovolumic contraction time plus isovolumic relaxation time divided by ejection time. Myocardial and skeletal muscle damages were assessed by serum levels of cardiac troponin I (cTnI), creatine (phospho) kinase, lactate dehydrogenase and aspartate aminotransferase. Serum magnesium level was also determined. According to treatment response, dogs were divided into the survivor (n=20) and non-survivor groups (n=23). Seven healthy dogs served as controls. The mean value of the Tei index was higher in non-survivors, compared with survivors (p<0.02) and healthy controls (p<0.01). Serum level of cTnI in non-survivors was higher than that of survivors and controls (p<0.05). Tei index showed the highest sensitivity and specificity to predict mortality. The findings of an elevated Tei index and an increase in serum cTnI are factors associated with a poor prognosis in cases of canine parvovirosis. 相似文献

Oriental beech (Fagus orientalis) is one of the main tree species in Turkey. In this study, 3-year storage of oriental beechnuts from eight Turkish provenances
was researched. Beechnuts were stored at −6°C in sealed containers. The average germination percentages of over all provenances
were 91.67, 75.92, and 76.75%, prior to initial storage, after 1 year in storage, and after 3 years in storage, respectively.
There were significant decreases in the germination percentages of seven provenances while one provenance retained its high
initial germination ability over a 3-year storage period. The loss of viability initiated from the radicle and the plumula
in stored beechnuts. The average mean germination times were 10.43, 10.22, and 11.89 weeks prior to storage, after 1 year
in storage, and after 3 years in storage, respectively. The beechnuts stored for 3 years germinated significantly later than
both fresh beechnuts and beechnuts stored for 1 year in terms of average mean germination time. This study showed that oriental
beechnuts can be stored in a dormant state for at least 3 years at low temperature (−6°C) with a low moisture content (about
6–7%). 相似文献
