Influence of Argan Kernel Roasting-time on Virgin Argan Oil Composition and Oxidative Stability     

Harhar H  Gharby S  Kartah B  El Monfalouti H  Guillaume D  Charrouf Z 《Plant foods for human nutrition (Dordrecht, Netherlands)》2011,66(2):163-168

Virgin argan oil, which is harvested from argan fruit kernels, constitutes an alimentary source of substances of nutraceutical value. Chemical composition and oxidative stability of argan oil prepared from argan kernels roasted for different times were evaluated and compared with those of beauty argan oil that is prepared from unroasted kernels. Prolonged roasting time induced colour development and increased phosphorous content whereas fatty acid composition and tocopherol levels did not change. Oxidative stability data indicate that kernel roasting for 15 to 30 min at 110 °C is optimum to preserve virgin argan oil nutritive properties.  相似文献   

Haematopoiesis in the head kidney of common carp (<Emphasis Type="Italic">Cyprinus carpio</Emphasis> L.): a morphological study     

Kondera E 《Fish physiology and biochemistry》2011,37(3):355-362

The morphogenesis of head kidney haematopoietic cells in common carp has been shown to be very similar to that of higher vertebrates. The erythropoietic series consisted of the erythroblasts (basophilic, polychromatic and orthochromic), young erythrocyte and erythrocyte. The morphological changes that occur during maturation process are reduction in size and further increase at mature stage, gradual chromatin condensation and the increase in haemoglobin content. Maturation stages of neutrophils and basophils encompassed the young progranulocyte, progranulocyte and metagranulocyte. The early blast cells, basophilic lineage and lymphocytes were regularly present in kidney. In the monocytoid series in kidneys, promonocytes and mature monocytes were observed. Precursor stages of the eosinophile and thrombocyte were not discernible (although mature cells were observed). Lymphoid cells were the most abundant, followed by granuloid, thrombocyte, erythroid, blast and monocytoid cells. The neutrophilic progranulocyte was the most frequent granuloid cell. The lymphocyte was the most frequent cell in the kidney and the most numerous of the lymphoid lineage.  相似文献   

Adapting a scenario tree model for freedom from disease as surveillance progresses: The Canadian notifiable avian influenza model     

Jette Christensen  Farouk El Allaki  André Vallières 《Preventive veterinary medicine》2014

Scenario tree models with temporal discounting have been applied in four continents to support claims of freedom from animal disease. Recently, a second (new) model was developed for the same population and disease. This is a natural development because surveillance is a dynamic process that needs to adapt to changing circumstances – the difficulty is the justification for, documentation of, presentation of and the acceptance of the changes.  相似文献   

Interrelationship between milk constituents,serum oestradiol and vaginal mucus indicators of oestrus in Egyptian buffaloes     

M. M. M. Kandiel  R. A. M. El‐Naggar  A. E. Abdel‐Ghaffar  G. A. M. Sosa  N. A. Abou El‐Roos 《Journal of animal physiology and animal nutrition》2014,98(1):197-200

The intensity of heat signs in buffaloes is generally low and the incidence of suboestrus varied from 15 to 73% (Buffalopedia). The objective of this study was to investigate the feasibility of monitoring the changes in some milk constituents, oestradiol levels and electrical conductivity of vaginal mucus during peri‐oestrous period in prediction of the timing of oestrus in buffaloes. Twenty‐one Egyptian buffaloes aged 3–9 year, 1st–6th lactations, were examined by oestrous detector and ultrasonographically for monitoring the ovarian and uterine activity for 7 days around the time of standing oestrus. Sodium, potassium, chloride and lactose were assayed in aqueous phase of milk; besides, oestradiol was estimated in serum. Current results declared highly significant acute changes in milk constituents at the time of oestrus characterized by peaking of chloride and sodium levels and lowering of potassium and lactose values. The alternation in milk composition when arranged in decreasing order of magnitude, sodium was the highest (77.78 ± 0.69%), followed by chloride (61.60 ± 1.52%) and potassium (?58.14 ± 10.89%). Concomitantly, milk lactose decreased by 26.07 ± 7.97% compared to baseline levels. Synchronously, vaginal electrical resistance (VER) showed a significant (p < 0.01) decrease, but serum oestradiol 17β levels surged (59.93 ± 7.29 pg/ml) on day of oestrus. Serum oestradiol level was negatively correlated with VER (r = ?0.577), potassium (r = ?0.661), positively correlated with chloride (r = 0.707) and sodium (r = 0.579) and not correlated with lactose levels. These results for the first time suggested that the changes in constituents of milk during peri‐oestrous period may be used as a practical non‐invasive indicator for oestrous detection and prediction of ovulation in Egyptian buffaloes.  相似文献   

Evaluation of the sedative,analgesic, clinicophysiological and haematological effects of intravenous detomidine,detomidine‐butorphanol,romifidine and romifidine‐butorphanol in standing donkeys     

M. H. El‐Kammar  S. B. Gad 《Equine Veterinary Education》2014,26(4):202-207

The aim of this investigation was to determine and evaluate the sedative, analgesic, clinicophysiological and haematological effects of intravenous (i.v.) injection of detomidine, detomidine‐butorphanol, romifidine and romifidine‐butorphanol. Six standing donkeys were used. Each donkey received 4 i.v. treatments and the order of treatment was randomised with a one‐week interval between each treatment. We found that i.v. injection of a combination of detomidine‐butorphanol or romifidine‐butorphanol produced potent neuroleptanalgesic effects thus providing better, safe and effective sedation with complete analgesia in standing donkeys compared with injection of detomidine or romifidine alone. The changes and reduction in pulse rate were within acceptable limits. The changes in clinicophysiological, haematological and biochemical values were mild and transient in these clinically healthy donkeys.  相似文献   

Peptide profile of the sardine protein hydrolysate affects food utilization and intestinal microbiota of Nile tilapia     

Ha  Natalia  Cipriani  Luiz Augusto  de Oliveira  Nandara Soares  Uczay  Juliano  Pessatti  Marcos Luiz  Fabregat  Thiago El Hadi Perez 《Aquaculture International》2022,30(1):365-382

The present study evaluated effects of the degree of hydrolysis and peptide profile of sardine (Sardinella sp.) protein hydrolysates (SPH) from muscle tissue wastes on productive performance, body composition, hematological parameters, biochemical parameters of metabolism, antioxidant response, and intestinal microbiology tilapia (Oreochromis niloticus). Diets containing three SPH with different degrees of hydrolysis (low: 5.5%; intermediate: 27.9%, and high: 62.5%) were compared to a control diet with fish meal. The experimental design was completely randomized with four treatments and five repetitions. One hundred eighty tilapia juveniles (6.16?±?2.0 g) were distributed in 20 polyethylene tanks of 70 l of useful volume and were evaluated during 56 days. No direct relationship was observed between the degree of hydrolysis of SPH and fish productive performance. Feed consumption was reduced in all diets with SPH (means 53.03 g) compared to the control group (65.91 g), which impaired fish growth and metabolic reserves. Feed utilization was affected by the SPH peptide profile. SPH with a more diverse peptide profile (mean 1.40) had a feed efficiency similar to the control diet (1.22). Changes in biochemical and metabolic parameters in tissues, oxidative response, and microbial populations were observed but may be associated with the low consumption of diets containing SPH. Results suggest that it is necessary to properly characterize hydrolysates and understand their composition before applying fish feed.

Capillary flow responses in a soil–plant system for modified subsurface precision irrigation     

Mohamad Shukri Bin Zainal Abidin  Sakae Shibusawa  Motoyoshi Ohaba  Qichen Li  Marzuki Bin Khalid 《Precision Agriculture》2014,15(1):17-30

Water movement in a soil–plant system was evaluated based on capillary flow in a modified subsurface irrigation system that incorporates a plant-water measuring device. Water from a reservoir tank located underneath the plant pot was supplied to the root zone through a fibrous medium. Evapotranspiration was measured from the water uptake and evaluations were performed based on soil moisture distribution and mass balance. Potential evapotranspiration was used as a reference for the plant–water uptake. Data were obtained from a test plant provided with the modified subsurface irrigation system. The plant was grown in a phytotron under controlled air temperature and humidity, and a comparison was made for different levels of soil moisture condition. The experimental results confirmed the operational efficiency of the modified subsurface irrigation system for precision irrigation.  相似文献   

The induction of mutations in chrysanthemum using X- and gamma radiation     

G. J. Dowrick  A. El Bayoumi 《Euphytica》1966,15(2):204-210

Plants of the Chrysanthemum variety New Princess were irradiated with X- and gamma rays at dose rates varying between 500–2000r X-rays and 1–4 Krad gamma rays. Flower colour changes were induced by both types of radiation and these were accompanied by change in chromosome number and by chromosome fragmentation. Optimum doses were 1000r X-rays and 1 Krad gamma rays. Most of the changes resulted from loss of pigmentation but a number with deeper colours were found. The frequency of mutation was directly proportional to the dose. Other phenotypic changes were also observed. The mutants arise by the formation of chromosomal chimaeras or by the re-arrangement of pre-existing chimaeras.  相似文献   

Effect of high temperature on incompatibility in radish   总被引：1，自引：0，他引：1  

A. I. M. El Murabaa 《Euphytica》1957,6(3):268-270

Summary Clones of radish plants were cross-pollinated or selfed at 17 and 26 °C. In crosscompatible plants the fruit set; the average number of seeds per fruit and the total seed yield were decreased at 26 °C. In incompatible plants the fruit set and the total seed yield were increased when selfing was done at the higher temperature. It is concluded that while high temperature has an unfavourable effect on seed set of radish plants, it also weakens the incompatibility reaction between pollen and style, so that the result is a small increase in yield.  相似文献   

Phylogenetic analysis of partial sequences from Fig mosaic virus isolates in Turkey     

Eminur Elçi  Çiğdem Ulubaş Serçe  Kadriye Çağlayan 《Phytoparasitica》2013,41(3):263-270

Fig mosaic virus (FMV), which was described recently, is the only characterized causal agent of fig mosaic disease (FMD). It has six RNA segments and belongs to the Bunyaviridae family. In order to determine the genetic diversity of Turkish FMV isolates, the most common fig cultivars showing FMD symptoms were collected from different fig-growing provinces of Turkey. Nucleoprotein (Np) and Glycoprotein (Gp) gene-specific primers of FMV were used for RT-PCR analysis. According to RT-PCR results, 71 of 90 samples from 20 different cultivars and unknown fig seedlings were found to be infected by FMV. Among them, 41 isolates were sequenced and subjected to phylogenetic analyses based on the partial Gp and Np sequences at the amino acid level by the neighbor-joining method. The isolates showed more than 80% identity with reference FMV isolates (Acc. nos. FM991954.1 and FM864225.2). Based on phylogenetic analysis, the sequences clustered into two main groups for Np and Gp regions. Significant relationships between FMV isolates based on geographic origin and cultivars were not observed.  相似文献
