Oculocardiac reflex induced by zygomatic arch fracture in a crossbreed dog

A 3-year-old crossbreed male dog was presented with a history of blunt facial trauma. Skull radiographs showed right zygomatic arch fracture. An electrocardiogram revealed bradycardia, first-degree atrioventricular block and QT prolongation. Standard biochemical profile including electrolytes was normal. Atropine response test (0.04 mg/kg intravenously) restored normal sinus rhythm at a rate of 140 bpm with normal QT and PR intervals. This observation is consistent with oculocardiac reflex secondary to zygomatic arch fracture.     

Survey of <Emphasis Type="Italic">Sarcocystis</Emphasis> infection in slaughtered cattle in Kerman,Iran

The parasite of genus Sarcocystis is one of the most commonly found parasite in domestic animals worldwide. Some species of Sarcocystis cause important economic loss when causing clinical and sub clinical disease. The aim of this study was to determine the prevalence of Sarcocystis in slaughtered Cattle in Kerman, Iran. The prevalence of Sarcocystis spp. infection was investigated in 480 cattle, slaughtered from May 2005 to February 2006 in the Kerman, Iran using naked eye examination for macroscopic Sarcocysts, and peptic digestion, muscle squash, squeezing methods for microscopic types. Muscles from heart, tongue, and esophagus, cervical and abdominal muscles of 480 slaughtered cattle were examined for Sarcocystis cysts. The prevalence of microscopic Sarcocystis cysts in cattle was detected in 100% and there was no macroscopic cyst in examined cattle.     

Kinetics of substrate oxidation and hydrogen peroxide production by Mycoplasma mycoides subsp. mycoides Large Colony (LC) type and Mycoplasma mycoides subsp. capri

Mycoplasma mycoides subsp. mycoides Large Colony (LC) type is a pathogen of goats causing contagious agalactia and respiratory disease, found on all continents where small ruminants are kept. It shares close genetic characteristics with M. mycoides subsp. capri. Substrate oxidation by 22 strains of M. mycoides subsp. mycoides LC from nine countries was compared with that of eight strains of M. mycoides subsp. capri from five countries. There was considerable similarity in the substrates used, but substrate saturation coefficients (K_s) varied for different substrates. Substrate utilization patterns and K_s values did not (1) significantly differentiate the LC strains from each other, (2) show any correlation with geographical origin, or (3) distinguish the LC strains from the capri strains. These results support previous studies justifying the reclassification of these subspecies as a single species.     

Serum lipid and lipoprotein parameters of Turkman horses

BACKGROUND: Lipid transport systems in animals have been evaluated both as experimental models for lipid and lipoprotein metabolism in humans and to gain insight into the lipid metabolism of specific breeds. The Turkman horse is a pure-blooded horse that lives on the margins of the Caspian Basin; information about serum lipids and lipoproteins in this breed is lacking. OBJECTIVE: The purpose of this study was to evaluate serum lipid and lipoprotein concentrations in clinically healthy Turkman horses. METHODS: Concentrations of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDL-C), and very low density lipoprotein cholesterol (VLDL-C), and lipoprotein electrophoretic patterns were determined in serum samples from 48 Turkman horses of both sexes and 0-12 years of age. Results were analyzed by 1-way ANOVA. RESULTS: In both sexes and all age groups, the relative percentages of LDL-C (44.2-64.3%) were higher than those of HDL-C (29.7-47.1%) and VLDL-C (5.9-9.0%). Serum concentrations of TG and TC were significantly higher in male (0.45 +/- 0.12 mmol/L; 2.70 +/- 0.45 mmol/L) than in female (0.34 +/- 0.1 mmol/L; 2.15 +/- 0.3 mmol/L) horses in most age groups. The relative percentages of alpha- and beta-lipoproteins in electrophoretic tracings were 62.77 +/- 5.05% and 36.67 +/- 4.29%, respectively. CONCLUSION: Serum lipid and lipoprotein values in Turkman horses differ from those of other equine breeds, and may be useful for evaluating metabolic diseases in this species.

Effect of Delayed Icing on the Microbiological,Chemical, and Sensory Properties of Caspian Sea Golden Grey Mullet (Liza aurata)

Research has shown that fresh fish is an extremely perishable food as compared to other food commodities. In this study, quality deterioration during storage of golden grey mullet (GGM) iced for 0, 6, and 12 h after landing was monitored. Microbiological indices (total viable count, TVC; psychrophilic counts, PTC; lactic acid bacteria, LAB; and Enterobacteriaceae counts, EBC), chemical parameters (pH; total volatile basic nitrogen, TVB-N; peroxide value, PV; thiobarbituric acid, TBA; and free fatty acids, FFA) values increased over the preicing duration. Delayed icing did not lead to significant increases (p > 0.05) in TVC, PTC, LAB, and EBC throughout the period of storage. All chemical indices increased during storage (p < 0.05). This study showed that sensorial analysis of GGM correlated well with microbiological analysis. Results of this study based on the microbiological and raw fish sensorial data indicated that the shelf life of GGM stored in ice immediately after catch was approximately 10–11 days, while the 6- and 12-h delays in icing shortened the shelf life to approximately 6–7 and 2–3 days, respectively.     

Nutrient Accumulation in Faba Bean Varieties

Increasing the amount of nutrients in plant-based foods will help to improve the nutritional status of people in the World. Faba bean (Vicia faba L.) as a staple food in developing countries has the potential to provide many nutrients in human diets. The objective of this study was to characterize the nutrient concentrations in leaf, pod, and seed of faba bean varieties. A field study was conducted with six faba bean varieties. Variation in the elemental concentrations of nutrients and protein occurred among varieties and different parts of the plants. The highest concentrations of nitrogen, phosphorus, potassium, zinc, or copper and protein were in the seeds. However, the highest accumulation of calcium, magnesium, iron, or manganese was in the leaves. We recommend that faba bean can be considered as a valuable crop in the diet of nutrient-deficient consumers due to high concentration nutrients in edible parts of the plant.     

Different K:Ca ratios affected fruit color and quality of strawberry ‘Selva’ in soilless system

High quality fruit production is the cornerstone of marketability. Optimum plant performance depends on the balanced and timely availability of mineral nutrients. In addition to element concentrations, the ratio of nutrient elements in solution plays a determinative role in growth, productivity, quality, and nutrients uptake. In this experiment, the effects of different Potassium:Calcium (K:Ca) ratios (1.6, 1.4, 1.2, 1, 0.85, and 0.6) in nutrient solution were studied on quality attributes of strawberry ‘Selva’. The highest and lowest leaf number and leaf area were observed in K:Ca 1.4 and 1, respectively. The highest fruit pH, electrical conductivity, total soluble solids/titratable acidity ratio, vitamin C content, ellagic acid, and color were resulted in K:Ca (1.4) ratio. K:Ca (1.6) ratio produced the highest content of protein. Moreover, K:Ca (0.85) ratio was the most effective treatment on fruit firmness. The increased quality attributes were observed in high K:Ca ratios, hence low K:Ca ratio resulted in increased fruit firmness. In conclusion, nutrient solution containing K:Ca ratios between 1 and 1.6 were suitable for producing strawberry ‘Selva’. Taken together, K:Ca (1.4) was an appropriate ratio for producing strawberry ‘Selva’ in soilless culture with coconut fiber: perlite medium.     

Investigating Iranian Farmers' Satisfaction With Agricultural Extension Programs Using the American Customer Satisfaction Index

The aim of this article is to investigate and measure farmers' satisfaction regarding extension services to better understand why farmers do or do not participate in such programs in Iran. Our study sample consisted of 240 farmers selected through simple quota random sampling (160 male and 80 female) from a list of names from the extension organization. Data were gathered through a face-to-face survey of farmers. Structural equation modeling analysis revealed that perceived quality and perceived value significantly predicted farmers' overall satisfaction. Furthermore, farmer satisfaction can predict farmers' loyalty to extension program activities. From a practical point of view, the present study provides a justification for using perceived quality and perceived value in policy and decision making that seeks to encourage farmers to use agricultural extension programs (AEPs).     

Soil and nutrient losses due to root crops harvesting: a case study from southwestern Iran

Although root crops are widely cultivated in Iran, little is known about soil loss due to crop harvesting (SLCH). We assessed the annual exported soil, soil organic matter (SOM) and nutrients from 47 farms under root crops in southwestern Iran. Soil losses for garlic, potato, sugar beet, radish and beetroot were estimated as 6.27, 2.52, 2.26, 4.10 and 6.95, Mg ha^?1, respectively, which on average was of the order of soil losses by water erosion in the watershed basins of Iran. Total N, P₂O₅ and K₂O losses were estimated as 36.61, 1.10 and 31.50 kg ha^?1 and their costs as 18.24, 0.74 and 19.93 USAlthough root crops are widely cultivated in Iran, little is known about soil loss due to crop harvesting (SLCH).

For the whole country, total soil, N, P₂O₅, K₂O and SOM losses for garlic, potato and sugar beet were estimated as 731.7 × 10³, 836, 27, 476 and 14.5 × 10³ Mg, respectively (radish and beetroot were excluded due to no reliable data on their planted areas). Correlation analysis showed no significant relationship between soil properties and SLCH (except soil moisture content for radish and clay content for beetroot). The findings indicated that the exported soil, SOM and nutrients were at such levels that SLCH should be considered in soil erosion studies.
