    Full Text Available Fertility rate is an economically important trait in sheep, which is influenced by genetic and environment. So far, three genes have been identified that affects this trait, one of them would be the BMP family, the most famous one is BMP15. Different mutations in the BMP15 gene, increases reproductive performance and growth rate in sheep. The aim of this study was to investigate the genetic and phylogenetic of BMP15 gene sequence in Iranian Sangsari sheep. For this purpose, the blood samples from 20 animal of Damghan station were collected. After DNA extracting, a segment of 222 bp of exon 2 of BMP15 gene was amplified using polymerase chain reaction. Then, all of the PCR products were sequenced. The results showed existence of four haplotypes and three significant mutations of the gene that which one of them was seen for first. In order to determine the genetic distance of Sansari sheep with other animals especially sheep breeds about 103 sequences were taken from Genebank, Then, phylogenetic trees were drawn. Genetic distances and nucleotide differences were calculated. The results showed that goat, cattle and buffalo have minimum genetic distance and monkey, human and mouse have maximum distance with Sangsari sheep and native Hindi and Kashmiri sheep have not any differences with Iranian Sangsari sheep.

    Full text: Iranian livestock diversity is still largely unexplored, in spite of the interest in the populations historically reared in this country located near the Fertile Crescent, a major livestock domestication centre. In this investigation, the genetic diversity and differentiation of 10 Iranian indigenous fat-tailed sheep breeds were investigated using 18 microsatellite markers. Iranian breeds were found to host a high level of diversity. This conclusion is substantiated by the large number of alleles observed across loci (average 13.83, range 7–22) and by the high within-breed expected heterozygosity (average 0.75, range 0.72–0.76). Iranian sheep have a low level of genetic differentiation, as indicated by the analysis of molecular variance, which allocated a very small proportion (1.67%) of total variation to the between-population component, and by the small fixation index (FST = 0.02). Both Bayesian clustering and principal coordinates analysis revealed the absence of a detectable genetic structure. Also, no isolation by distance was observed through comparison of genetic and geographical distances. In spite of high within-breed variation, signatures of inbreeding were detected by the FIS indices, which were positive in all and statistically significant in three breeds. Possible factors explaining the patterns observed, such as considerable gene flow and inbreeding probably due to anthropogenic activities in the light of population management and conservation programmes are discussed.

    Full Text Available The Makuie sheep is a fat-tailed sheep breed which can be found in the Azerbaijan province of Iran. In 1986, a Makuie sheep breeding station was established in the city of Maku in order to breed, protect and purify this breed. The genetic parameters for birth weight, weaning weight (3 months, 6-month, 9-month and yearling weight, and average daily gain from birth to weaning traits were estimated based on 25 years of data using DFREML software. Six different models were applied and a likelihood ratio test (LRT was used to select the appropriate model. Bivariate analysis was used to define the genetic correlation between studied traits. Based on the LRT, model II was selected as an appropriate model for all studied traits. Direct heritability estimates of birth, weaning, 6-month, 9-month and yearling weights and average daily gain from birth to weaning were 0.36, 0.41, 0.48, 0.42, 0.36 and 0.37, respectively. Estimates of direct genetic correlation between birth and weaning weights, birth and 6-month weights, birth and 9-month weights, as well as between birth and yearling weights were 0.57, 0.49, 0.46 and 0.32, respectively. The results suggest there is a substantial additive genetic variability for studied traits in the Makuie sheep breed population, and the direct additive effect and maternal permanent environment variance are the main source of phenotypic variance.

    Full Text Available Background: Multiple births occur frequently in some Iranian sheep breeds, while infertilityscarcely occurs. Mutation detection in major fecundity genes has been explored in most of Iraniansheep flocks over the last decade. However, previously reported single nucleotide polymorphisms(SNPs for bone morphogenetic protein receptor-(BMPR-1B and growth differentiation factor GDF9( known to affect fertility have not been detected. This study was conducted to assess whetherany significant mutations in GDF9 were extracted from slaughtered ewe ovaries of Iranian Afsharisheep breed.Materials and Methods: Ovaries defined as poor, fair, and excellent quality based on externalvisual appearance of follicles were used for histology and RNA extraction processes. High qualityRNAs underwent reverse transcriptase-polymerase chain reaction (RT-PCR from GDF9 mRNA,and the products sequenced.Results: No streak ovaries, which are considered indicators of infertility due to homozygocity forsome mutations in GDF9 and BMP15, were found. Sequencing results from GDF9 cDNA showedthat G2 (C471T, G3 (G477A, and G4 (G721A mutations were observed from 1, 4, and 1 out of12 ewes, respectively. Though all 3 mutations were previously reported, this is the first report ontheir presence in Iranian breeds. The first and second mutations do not alter the amino acids, whileG4 is a non-conservative mutation leading to E241K in the prohormone.Conclusion: As the G4 mutation was observed only in ovaries defined superficially as top quality,it could be considered as one of reasons for higher ovulation rate in some sheep. Furthermore sincemultiple mutations were observed in some cases, it might be possible that combinations of minormutations in GDF9 and BMP15 interact to affect fecundity in some Iranian sheep breeds.

    Full Text Available Growth hormone (GH is a peptide hormone that stimulates growth and cell reproduction in humans and animals. It is a 191-amino acid, single chain polypeptide hormone which is synthesized, stored, and secreted by the somatotroph cells within the lateral wings of the anterior pituitary gland. The goal of this research was to clone and sequence sheep growth hormone of Lori Bakhtiary breed in Iran. For this purpose, RNA was extracted from the pituitary gland of freshly slaughtered sheep and cDNA of growth hormone produced. The T/A cloning technique was used to clone the cDNA of growth hormone and then the synthesized construct was transferred into E. coli as the host. Once the correct recombinants were further confirmed by colony PCR or restriction enzyme digestion, sequencing was done. The sequencing results showed that, the length of sheep growth hormone cDNA was 690 bp fragments. Comparison of sequence of growth hormone inside the synthesized construct with those recorded in Genebank (NCBI, Blast indicated high degrees of similarity between Iranian native sheep and other sheep breeds of the world.

    The objective of this study was to compare hoof anatomy, hoof growth pattern, and hoof weight-bearing surface of six different Iranian sheep breeds to identify possible differences in the hoof anatomical features that could help to minimize adverse effects of hoof trimming methods. Front and hind hooves of 2-year-old, previously untrimmed, pastured dairy ewes of six Iranian breeds (Afshari, Moghani, Kurdi, Makoui, Chaleshtori, and Lori-Bakhtiari; n = 180 ewes; 30 ewes per breed) were collected after slaughter. Medial and lateral claws were incised sagittally and anatomical measurements such as toe length, heel height, toe height, sole thickness, sole length, and toe angle were recorded in each claw. Data were analyzed using mixed model equations including breed, claw (lateral or medial), hoof (front or hind) and their interactions as fixed effects, and ewe as random effect. Breed differences were observed for all hoof measurements (P < 0.05). Chaleshtori sheep had higher measurements for most of the traits studied while Afshari and Makoui sheep had lower measurements. All measurements, except for toe length and toe height to solar surface to heel height ratio, were significantly greater in the front hooves than in the hind hooves (P < 0.05). Soles were longer in the medial claws compared to the lateral claws of the front hooves (P < 0.05). Results suggest the observed breed differences could interfere with establishing a standard, uniform hoof trimming method for sheep. For instance, it might be possible that while Afshari and Makoui sheep could require more conservative trimming, Chaleshtori sheep could require to be trimmed more. In consequence, hoof trimming methods might need to be adjusted to specific breed characteristics to avoid possible tissue damage.

    Full Text Available Introduction It has been estimated that PBP production based on fresh weight in Iran is over 400,000 MT annually. Pistachio by-products consist of 53.50% external hull (epicarp with the remaining composed of leaves, mesocarp and kernel. The results of few studies showed feeding of low levels of PBP had no effects on sheep, dairy cow and goat performance. Ensiled of PBP with PEG, NaOH and urea then treated by electron irradiation could be caused to better nutrition value via deactivation of tannins. The aim of this study was to survey the effect of diets containing pistachio by products treated by electron irradiation, NaOH, and PEG on nutrients digestibility and performance of finishing Zandi lambs. Materials and methods Twenty male Zandi lambs with the initial average body weight of 21±1.52 kg were housed in individual pens and were allocated to four dietary treatments in a completely randomized design for 70 days. The basal diet consisted of 220 g/kg DM PBP, 130 g/kg DM wheat straw and 650 g/kg DM barley based concentrate. The four dietary treatments included control diet (Treatment 1; basal diet containing 22% PB, ER-PBP (Treatment 2; containing 22% electron irradiated PBP, NaOH-PBP (Treatment 3; containing 22% NaOH treated PBP and PEG-PBP (Treatment 4; PEG added to basal diet as 15 g/kg of diets DM. Throughout the 70 d experiment, body weight was measured weekly. Feed intake and ort of lambs were recorded and sampled daily for determination of nutrient intake of DM, CP (N × 6.25, EE and NDF as describes before. Apparent total digestibility of nutrients was estimated by the marker ratio technique using acid insoluble ash (AIA as an internal marker. Blood samples (10 ml were taken from jugular vein of lambs before morning feeding on d 70 of experiment. The serum concentrations of total protein (TP, albumin, creatinine, glucose and urea were determined using commercial laboratory kits (Pars Azmun Laboratory, Tehran, Iran and an auto analyzer

    Full Text Available Abstract Background Transfer of pesticides from environment to animal products is inevitable, so the purpose of the present work was to evaluate phosalone consumption via feeding with or without sodium bentonite (SB on performance, blood metabolites and its transition to milk of Iranian Baluchi sheep. Methods Twenty Baluchi ewes were divided into four treatments (P1 as control, P2, P3, and P4 of five animals in which phosalone, an organophosphate pesticide, was given via diet (only for P2 and P3 at a dose of 280 mg/sheep/day for 63 consecutive days. The SB (32 g/sheep/day; for P3 and P4 was also evaluated for its ability to reduce deleterious effects of phosalone in the sheep diets. The control group (P1 did not receive any phosalone and SB during the experiment. Sampling was conducted in two periods of time including weeks 5 and 9. Results Phosalone residues were observed in the milk samples of P2 and P3 groups during two sampling periods. During period 1, the transfer rate of phosalone from feed to milk was 0.23 and 0.02%, respectively for the contaminated diets (P2 and P3, which is relatively similar to period 2 (0.22 and 0.02%. Only 0.34 (period 1 and 0.36% (period 2 of phosalone residue are excreted in the feces of P2 group following its daily consumption.

    Full Text Available Introduction The mating of related individuals produces an inbred offspring and leads to an increased homozygosity in the progeny, genetic variance decrease within families and increase between families. The ration of homozygosity for individuals was calculated by inbreeding coefficient. Inbred individuals may carry two alleles at a locus that are replicated from one gene in the previous generations, called identical by descent. The inbreeding coefficient should be monitored in a breeding program, since it plays an important role at decreasing of homeostasis, performance, reproduction and viability. The trend of inbreeding is an indicator for determining of inbreeding level in the herd. Inbreeding affects both phenotypic means of traits and genetic variances within population, thus it is an important factor for delimitations of genetic progress in a population. Reports showed an inbreeding increase led to decrease of phenotypic value in some of the productive and reproductive traits. Materials and Methods In the current study, the pedigree data of 14030 and 6215 records of Baluchi and Iranblack lambs that collected from 1984 to 2011 at the Abbasabad Sheep Breeding Station in Mashhad, Iran, 3588 records of Makoei lambs that collected from 1994 to 2011 at the Makoei sheep breeding station and 6140, records of Zandi lambs that collected from 1991 to 2011 at the Khejir Sheep Breeding Station in Tehran, Iran were used to estimating the inbreeding coefficient and its effects on lamb survival in these breeds. Lamb survival trait was scored as 1 and 0 for lamb surviving and not surviving at weaning weight, respectively. Inbreeding coefficient was estimated by relationship matrix algorithm (A=TDT' methodology using the CFC software program. Effects of inbreeding coefficient on lamb survival were estimated by restricted maximum likelihood (REML method under 12 different animal models using ASReml 3.0 computer programme.

    The aim of this study was to evaluate the fertility response of artificial insemination (AI) methods with fresh and frozen sperm in sheep. In experiment 1, one hundred and fifty fat tailed Zandi ewes were assigned into 3 equal groups and inseminated with three AI methods consisting of vaginal, laparoscopic and trans-cervical AI with fresh semen. In experiment 2, a factorial study (3 AI methods × 2 extenders) was used to analyze the effects of three AI methods and two freezing extenders containing soybean lecithin (SL) or Egg yolk (EY) on reproductive performance of 300 fat tailed Zandi ewes. Also, total motility, progressive motility, viability and lipid peroxidation of semen were evaluated after freeze-thawing in two extenders. In result, there was no significant difference among three AI methods when fresh semen was used. In experiment 2, the highest percentage of pregnancy rate, parturition rate and lambing rate were obtained in laparoscopic AI group (P semen, trans-cervical AI was more efficient than vaginal method when frozen-thawed semen was used, but its efficiency was not as high as laparoscopic method. Also, SL extender can be an efficient alternative extender to preserve ram sperm during cryopreservation procedure without adverse effects of EY. Copyright © 2016. Published by Elsevier Inc.

    Turning preferences among 309 white-faced ewes were individually evaluated in an enclosed, artificially lit T-maze, followed by each ewe choosing either a right or left return alley to return to peers. Data recorded included time in the start box, time in the T-maze, exit arm chosen to leave the T-maze, and return alley. Right and left arms of the T-maze were chosen 65.7% and 34.3% of the time, respectively, while right and left return alleys were chosen 32.4% and 67.6%, respectively. Exit arm and return alley were not independently chosen (p laterality was not related (α =.05) to time of day the test was administered, ewe's age or genetics, most recent liveweight, or most recent shorn fleece weight. The mean time spent in the start box (21 s) was not related to exit arm (p =.947) or return alley (p =.779). Mean time (15 s) spent in the T-maze was not related to exit arm (p =.086) or return alley (p =.952). More research will be required to understand sheep turning laterality and how it can impact working facilities and research equipment.

    This article proposes an overview of the Iranian nuclear issue. The author first recalls that Iran has launched a nuclear program during the 1970's with the objective of building several nuclear power stations for electricity production. He evokes contracts signed by the Shah and the consequences of the Islamic revolution after which Iranian governments thought it was absurd to leave these constructions unfinished. The author outlines the several mistakes made by Western countries in their relationship with Iran, and those made by Iran (development of hidden nuclear program for example), which altogether leaded to the present crisis. The author discusses some legal aspects, notably the fact that Iran signed very early the NPT (non proliferation Treaty) as other countries who posses nuclear weapons, did not. He outlines the political challenges at different scales, regional as well as international, and finally discusses the uncertain perspectives

    Full Text Available Although Iranian regional music, like Iranian traditional[*] music, is basically monophonic and follows the rules of heterophony, we occasionally run across polyphonic pieces, although most have been unwittingly formed as such. This study shows that these polyphonic pieces could be found in the following forms: 1. The meeting of two vocal parts, where the second singer starts singing before the melody is completed by the first. 2. Imitations, as a result of singing the same melody by a few singers who consecutively start singing with some delay between their parts. 3. Simultaneous playing of variants of the same melody by two players (variant heterophony. 4. Changing between the soloist and the chorus (in the responsorial form or between one chorus and another (in an antiphoner[**] where a chorus begins the next part of the lyrics before the soloist or the other chorus is finished with their own part. 5. Polyphony resulting from the playing of a melody by a few singers where each singer sings the melody based on their own voice register depending on their physiological features. 6. Accompanying the first singer using alternate changes to the drone note or following the up-going or down-going movement of the melody in playing the tamira (in Lorestan, the dotār (in Khorasan and tamderā (in Turkman leads to the conscious parallelism of two voices. The radif of traditional music and the Iranian regional music, like those of other Middle East countries, is monophonic and follows the forms of heterophony; that is, the same melody is played and changed by two or more players. The change of a specific melody by two players, or a player and a singer, sometimes leads to the simultaneous playing of two different notes. Such an interference or combination of two sounds is a matter of heterophony, and by no means of harmony or accord. Interference of notes or combinations of notes in heterophony are not predictable. Since the melody is played extempore

    Thirteen sheep from a milk producing farm in the Canton of Grisons that presented chronic coenurosis were examined and subjected to treatment trials at the veterinary hospital in Zurich. Symptoms were first observed around two months after the import of two dogs from Italy (Abruzza) of which one was infected with Taenia multiceps and Echinococcus granulosus. The most frequently observed clinical symptoms of the sheep were reduced general condition, circling, reduced menace reflex, apathy, unsteady gait and head tilt. Analyses of cerebrospinal fluid revealed an increased leucocyte count in 3 sheep and eosinophilia in 4 sheep. In 4 animals that underwent computertomography, one or more hypodense, definable lesions were found in the brain. In 2 sheep surgical treatment and in 10 animals medical treatment with either Praziquantel (n=8) or Oxfendazol (n=2) was attempted. Only one animal treated with Praziquantel needed not to be euthanized. At necropsy, one or two coenurus cysts could be found either in a side ventricle (n=2), in the cerebellum (n=3) or in the cerebrum (n=7). The locations corresponded with the clinical findings. Despite Praziquantel or Oxfendazol treatment, living protoscoleces could be found in the parasite cysts [de

    Full Text Available This paper examines the complexity of the Iranian foreign policy through the case of Iranian nuclear program. The paper aims to assess foreign policy orientations and compares actions of the last three Iranian presidents, Mohammad Khatami, Mahmoud Ahmadinejad and current Hassan Rouhani in dealing with the international community (IC in pursuing its nuclear program. This assessment would not be complete without reference to the Iranian supreme leader Ali Khamenei who is actual head of the state and the most powerful political authority. This paper also relates Iranian foreign policy expectation to competing theories of international relations to identify the most dominant or the most consistent policy orientation. Its aim is to strengthen realist and power-based explanations that have dominated the discourse on Middle Eastern in general and Iranian foreign policy in particular. In this context, a number of questions will be addressed here. To what extend was Iranian negotiation with the IC over its nuclear program consistent throughout these three presidencies? What has changed, if anything, from Iranian foreign policy perspective and why? Can Iranian foreign policy behavior on this specific topic and in this specific time be explained through any international relations theory? As there are many other questions, so there are many theories to examine and explain true Iranian intentions, those below the surface of declared goals (Hadzikadunic, 2014. The methods employed in answering these questions are largely structured around a chronological account and comparative approach. It is also based on the analysis of foreign policy discourse and the assessment of key decision makers.

    During 1979-1980 acute fibrinopurulent bronchopneumonia resulted in high mortality or total loss of herds of bighorn sheep (Ovis canadensis) in California and Washington. Contact with domestic sheep occurred shortly before the onset of disease in each case. Circumstantial evidence indicated that the apparently healthy domestic sheep transmitted pathogenic bacteria to the bighorns, resulting in mortality. Pasteurella multocida and Corynebacterium pyogenes were isolated from pulmonary tissue of dead bighorns. The presence of domestic sheep may have been an important stress which initiated or compounded the disease.

    Full Text Available INTRODUCTION Human temporal bones are difficult to procure now a days due to various ethical issues. Sheep temporal bone is a good alternative due to morphological similarities, easy to procure and less cost. Many middle ear exercises can be done easily and handling of instruments is done in the procedures like myringoplasty, tympanoplasty, stapedotomy, facial nerve dissection and some middle ear implants. This is useful for resident training programme.

    Gaucher disease, an autosomal recessive lysosomal storage disorder caused by mutations in the β-glucocerebrosidase gene, was recently discovered in sheep on a "Southdown" sheep stud in Victoria, Australia. Clinical signs include neuropathy, thickened leathery skin, and ichthyosis, with lambs unable to stand from birth. Affected lambs were found to be deficient in glucocerebrosidase activity, and mutational analysis found them to be homozygous for the missense mutations c.1142G>A (p.C381Y) and c.1400C>T (p.P467L). In addition, four silent mutations were detected (c.777C>A [p.Y259Y], c1203A>G [p.Q401Q], c.1335T>C [p.I445I], c.1464C>G [p.L488L]). The human equivalent [C342Y] to the C381Y mutation leads to an acute neuronopathic phenotype in patients. Identification of an acute neuronopathic form of Gaucher disease in sheep provides a large animal model that will enable studies of pathology and evaluation of therapies to treat this common lysosomal storage disorder.

    Six Rocky Mountain bighorn sheep were raised in captivity from birth (n = 5) or taken from the wild as a lamb (n = 1). After the bighorn sheep were in captivity for over a year, 6 clinically normal domestic sheep were placed on the 2 ha of pasture on which the bighorn sheep were kept. Nasal swab specimens were obtained from all sheep at the time the domestic sheep were introduced. Pasteurella haemolytica was isolated from swab specimens obtained from 4 of 6 domestic sheep, but not from specimens obtained from the bighorn sheep. All 6 bighorn sheep died of acute hemorrhagic pneumonia after exposure to domestic sheep. Death in the bighorn sheep occurred on days 4, 27, 27, 29, 36, or 71 after initial exposure to domestic sheep. Pasteurella haemolytica was isolated from respiratory tract tissue specimens of all bighorn sheep at the time of death. None of the domestic sheep were clinically ill during the study. At the end of the study, 3 of 6 domestic sheep were euthanatized, and at necropsy, P haemolytica was isolated from 2 of them. The most common serotypes in bighorn and domestic sheep were P haemolytica T-3 and A-2. Other serotypes isolated included P haemolytica A-1, A-9, and A-11 in bighorn sheep and A-1 in domestic sheep. On the basis of results of this study and of other reports, domestic sheep and bighorn sheep should not be managed in proximity to each other because of the potential fatal consequences in bighorn sheep.

    Full Text Available The sheep is an important economic livestock species, contributing greatly to the Indian economy, especially in arid, semi arid and mountain areas. The current population in world is 1110.78 millions, around 44.85 millions (1987 sheeps in India (ICAR., 2002. Sheeps are mostly reared for meat and wool. The average annual wool production per sheep is between 3.5 to 5.5 kg of fine quality wool in Australia, New Zealand and U.S.S.R., where as in India except Magra sheep which annually yield more than 2 kg wool having staple length 5.8 cm, the average of rest of the wool produced is less than 1.0 kg per sheep of inferior quality (Banerjee G.C., 1998. Therefore many farmers in southern India adapted sheep rearing for meat production than for wool production. For yielding more production from sheep farming one should have sound knowledge of general information related to the reproduction and different breeding practices. [Vet. World 2009; 2(1.000: 43-44

    1. Most of the field studies on bloat are conducted with cattle and most of the laboratory experiments seeking to explain the various parameters associated with bloat are done with sheep. 2. Based on grazing behaviour, it would be expected that sheep might bloat more severely than cattle because they selectively choose to eat leaves over stems and chew what they ingest more frequently than cattle. Furthermore, sheep appear to select legumes over grasses because the legumes can be eaten more rapidly. However, because they are selective, sheep eat more slowly than cattle. Despite a higher bloat expectation, bloating in sheep is reported to be less of a problem than in cattle. 3. Although frothing of rumen ingesta was described earlier in cattle as the cause of acute legume bloat, experiments with frothy bloat in sheep preceded those in cattle. 4. Anti-frothing agents were used in sheep before cattle to treat acute legume bloat. 5. Experiments devoted to the study of eructation in ruminants were carried out on sheep, then cattle. 6. Convincing evidence that rumen motility does not cease during acute legume bloat was gathered using sheep. 7. Although the transected tracheal technique for the determination of the volume of eructated gas was developed with cattle, the pathway of eructated gas was confirmed with sheep. 8. All the current evidence accumulated from experiments with sheep supports the hypothesis that death due to legume bloat is caused by acute neural, respiratory, and cardiovascular insult resulting from the effect of the distended rumen on thoracic viscera, diaphragm, intercostal muscles, and the abdominal vena cava. 9. Experiments with sheep and cattle being fed scabrous and nonscabrous diets similar in chemical composition show that sheep are more resistant than cattle to the increase in intrarumen pressure, decline in rumen contraction amplitude, and decrease in rumen contraction frequency caused by nonscabrous diets. 10.

    Full Text Available Middle Eastern Muslim men have been historically subjected to stereotypical representations in the West. Although these men are categorically hypervisible for Western audiences as a similar type, among them Iranian men in particular, have been subject to a specific kind of marginalization. Following the 1979 Islamic revolution and the American hostage crisis in Iran, Iranian men and masculinity have become hypervisible as violent and religiously fanatic. While Western discourses of representation contributed greatly to the construction and representation of this specific kind of masculinity which marginalized and stigmatized Iranian men, Iranians themselves, have played a significant role in reaffirming this view. Ironically, contributing most to the reinforcement of this discourse has been Iranian women’s narratives in English in the West, in the form of memoirs and fictional accounts. These popular accounts have played a significant part in marginalizing and emphasizing a hypervisible and stereotypical representation of Iranian men. This paper considers the representation of Iranian men and masculinity as presented through Iranian women’s narratives in the West in English. By drawing on specific narratives and accounts, it examines how socio-political and historical contexts both in the West and in Iran, have led to Iranian women’s representation of Iranian men hypervisibly. Then, through an examination of some narratives by Iranian men, this paper examines how such representations have led to emphasizing the discourse of exclusion and otherness of Iranian men in the West, hampering the actual smooth integration of diasporic Iranian men into their adopted homes.

    Considerable advances have been made in the knowledge of the mechanisms and control of synthesis and degradation of proteins in animal tissues during the last decade. Most of the work on the measurement of synthetic and degradative rates of the mixed protein fraction from tissues has been conducted in the rat. There have, unfortunately, been few publications describing results of protein turnover studies with ruminants. Consideration is given here to the techniques used to measure protein turnover, and some of the results obtained, particularly with sheep, are summarized. No attempt has been made to discuss directly the situation in parasitized animals; rather the aim is to provide background information which complements other work dealing with the effects of parasites on the nitrogen metabolism of ruminants.

    Full Text Available Teaching English in an Iranian and Islamic culture poses complex questions for both teachers and learners. In this paper, the authors intend to shed light on what it means to teach English as a foreign language (TEFL in an Islamic-Iranian context. Having reviewed the colonial and postmodern views of English language teaching, the authors took a look beyond the current state of TEFL in Iran, which is marked by its continuing global tendency, and into the future with an emphasis on the importance of including the local specificities of the Iranian culture and religion. The status of the TEFL in Iran and the direction it should take in the future are accompanied by offering some solutions to inherent problems. Iranian TEFL is introduced as the successful assertion of Iranian local culture against the cultural and ideological domination of the West, which can be an antidote to the harshness of all marginalizations Iranians have suffered for centuries.

    2011-07-01

    Full Text Available In order to discuss and analyze the available information concerning the seasonal breeding behavior of sheep in Mexico, this review was conducted. We analyzed the neuroendocrine basis that modulate the annual reproductive cycle in sheep and then discussed the degree of reproductive seasonality in Creole sheep wool, breeds originating in high latitudes and hair sheep, mainly in Pelibuey ewes. The Creole sheep wool show continuous annual reproductive activity and short seasonal anestrous. The females of northern origin, express seasonal reproductive activity, similar to that observed in individuals geographically located at latitudes above 35º. Pelibuey sheep show variable annual reproductive behavior with reduced anestrus or lack thereof.  It is suggested that the neuroendocrine mechanisms regulating seasonal anestrus in ewes, are active in the sheep of northern origin that live in Mexico, in a manner contrary is not activated in Creole and hair sheep.

    Several factors such as season, genetics, social interaction and metabolic status control or modulate the reproductive capacity of sheep. In addition to these well-studied factors in sheep, the influence of emotional reactivity on the reproductive success of sheep has started to be investigated over the last two decades. In this paper, after briefly reviewing the impact of classical factors affecting reproduction in sheep, we define emotional reactivity and the expression of its inter-individual variability, named temperament. Then, following a description of the protocol to measure temperament in sheep and discussion on the heritability of temperament traits, we illustrate how this selection affects the reproductive biology of sheep. We will be mainly using results obtained from a unique flock of sheep selected for low or high emotional reactivity. In conclusion, we propose that energy partitioning could be one of the mechanisms by which selection for temperament in sheep affects the different steps of the reproductive cycle.

    The civil nuclear constitutes an alibi for Iran which the real aim is the access to the military nuclear power. It was probably the initial goal, before and after the 1979 revolution. The provocative speech of Iranian rulers on Israel constitute a reason to enrich uranium at military ends. But it appears that's not the only reason for Iran to pursue its nuclear program. Will not be efficient to begin sincere negotiations with Iran and to engage a policy of denuclearization of the region? Moreover the international interferences on the Iranian matters could be detrimental. Indeed, democratic freedoms won't spread in Iran, if the great decisions that concern the country don't take into account the national willing

    Context: Insomnia is one of the most prevalent sleep disorders characterized by sleep difficulty that impairs daily functioning and reduces quality of life. The burden of medical, psychiatric, interpersonal, and societal consequences of insomnia expresses the importance of diagnosing and treatment of insomnia. The aim of study was to investigate causes of insomnia from the viewpoint of Iranian traditional medicine. Evidence Acquisition: In this review study, we searched insomnia in a few of the most famous ancient textbooks of Iranian traditional medicine from different centuries. This books includeThe Canon of Medicine by Avicenna (the first version of Beirut), Zakhire Kharazmshahi by Jurjani (the scanned version of Bonyade Farhang-e Iran), Malfaregh by Razes (the first version of Iran University of Medical Sciences), and Aqili’s cure by Aqili (the first version of Iran University of Medical Sciences). Results: This study found that in Iranian traditional medicine manuscripts, insomnia was called sahar and even though many factors induce insomnia, most of them act through causing brain dystemperament. Conclusions: The brain dystemperament is considered one of the main causes of insomnia and insomnia can be well managed with an organized line of treatment, by correcting the brain dystemperament through elimination of causes. This study helps to find new solutions to treat insomnia. PMID:24829786

    Menorrhagia is a common problem. Medical management for menorrhagia includes hormonal and nonhormonal treatments. These treatments have different side effects, which reduce quality of life. Complementary and traditional medicines have been used to handle menorrhagia for centuries in many cultures. There is a lot of information and data in Iranian traditional documents or books about medicinal herbs that are used by Iranian traditional medicine scientists for the treatment of menorrhagia. The aim of this study was to review the approaches to menorrhagia in Iranian traditional medicine texts. In this study, some main Iranian traditional medicine manuscripts including Canon of Medicine and Al-Havi of Rhazes were studied to extract important information about menorrhagia management. Iranian traditional medicine physicians have relied on an organized system of etiological theories and treatments for menorrhagia. Their methods for menorrhagia management may be able to convince the desire of many women to preserve their uterus and avoid hormonal therapy. © The Author(s) 2015.

    The aim of the present study is to determine the characteristics of genotype and phenotype of Echinococcus granulosus derived from wild sheep and to compare them with the strains of E. granulosus sensu stricto (sheep-dog) and E. granulosus camel strain (camel-dog) in Iran. In Khojir National Park, near Tehran, Iran, a fertile hydatid cyst was recently found in the liver of a dead wild sheep (Ovis orientalis). The number of protoscolices (n=6,000) proved enough for an experimental infection in a dog. The characteristics of large and small hooks of metacestode were statistically determined as the sensu stricto strain but not the camel strain (P=0.5). To determine E. granulosus genotype, 20 adult worms of this type were collected from the infected dog. The second internal transcribed spacer (ITS2) of the nuclear ribosomal DNA (rDNA) and cytochrome c oxidase 1 subunit (COX1) of the mitochondrial DNA were amplified from individual adult worm by PCR. Subsequently, the PCR product was sequenced by Sanger method. The lengths of ITS2 and COX1 sequences were 378 and 857 bp, respectively, for all the sequenced samples. The amplified DNA sequences from both ribosomal and mitochondrial genes were highly similar (99% and 98%, respectively) to that of the ovine strain in the GenBank database. The results of the present study indicate that the morpho-molecular features and characteristics of E. granulosus in the Iranian wild sheep are the same as those of the sheep-dog E. granulosus sensu stricto strain.

    In a series of three experiments, isolates of Pasteurella haemolytica biotype A, serotype 2, ribotype reference WSU-1, from healthy domestic sheep, were inoculated intratracheally into eight bighorn sheep (Ovis canadensis canadensis) and seven domestic sheep with doses of bacteria ranging from 5.3 x 10(8) to 8.6 x 10(11) colony forming units. Seven of eight inoculated bighorn sheep died from acute pneumonia within 48 hr of inoculation, whereas all seven domestic sheep inoculated with comparable or greater doses of bacteria remained healthy. One contact control bighorn sheep also died 6 days after its penmates received P. haemolytica. Three other noncontact control bighorn sheep remained healthy during the experiments. Pasteurella haemolytica biotype A, serotype 2, ribotype reference WSU-1 in the inocula was recovered from one or more tissues from all bighorns that died; whereas, it was not detected in any bighorn sheep before inoculation. Three different ribotypes of P. haemolytica A2 were recovered from bighorn sheep; however, only the ribotype reference WSU-1 in the domestic sheep-origin inoculum was recovered from all dead bighorn sheep, and was not recovered from bighorn sheep that survived the experiments. Thus, a relatively nonpathogenic and common isolate of P. haemolytica from healthy domestic sheep was lethal in bighorn sheep under experimental conditions.

It was not determined whether these were mechanical or biological transmissions, although the results suggested mechanical transmission. Sheep keds were manually transferred from a BTV-host sheep to 18 susceptible test sheep. Of these, 10 were positive (5 with mild reactions), 6 questionable, and 2 negative for BTV. Three of the mildly reacting sheep and 3 of the questionable sheep had highly intensified reactions on challenge inoculation. Five of the positive sheep were immune on challenge inoculation. Blood from 2 positive reactors was subpassaged into susceptible sheep, which reacted with typical disease signs.

    Full Text Available BACKGROUND: This study aimed to compare Iranian elderly with the youth and middle aged population in terms of the prevalence of metabolic syndrome and its components in Iranian elderly METHODS: This cross-sectional study was conducted using the information from the third phase of Isfahan Healthy Heart Program. Male and female residents of Isfahan who aged over 19 years were selected by multistage cluster random sampling. A questionnaire including demographic characteristics, health status, medical history, medications used, as well as waist circumference, weight, height and systolic and diastolic blood pressures was completed for all participants. Fasting blood samples were obtained from all subjects and examined for fasting blood sugar and lipid profile. RESULTS: The prevalence of metabolic syndrome in individuals aged over 60 years was significantly higher than those under 60 (49.5% vs. 17.5%, respectively; P < 0.001. It was also more prevalent among elderly females than in males (59.2% vs. 39.8%, respectively; P < 0.005. Some anthropometric measures such as height, body mass index, abdominal circumference, waist-hip ratio, and waist to height ratio were significantly different in men and women below 60 years in comparison with those over 60 years (P < 0.05. Moreover, there were significant differences in most studied parameters between the elderly and non-elderly women (P < 0.001. Based on the findings of this study, the risk factors for cardiovascular diseases were significantly more prevalent in men and women over 60 years. T-test and Mann-Whitney were used for quantitative data and the square-chi test is performed for qualitative data.    CONCLUSION: This study showed that metabolic syndrome has a relatively high prevalence in Iranian elderly people (especially in women. Therefore, early diagnosis and management of the complication are recommended among this high-risk group. Keywords: Metabolic Syndrome, Elderly, Iran

    Full Text Available Background and Aim: Massage training and how the body is influenced by massage are common issues which are seriously under study and discussion in Iranian traditional medicine. Iranian physicians considered motion and massage as major principles of health maintenance.In this study, we examined the available literature of traditional medicine to evaluate location, purpose and use of massage therapy in Iranian medicine in comparison with other popular conventional styles.The aim of Iranian massage is to regulate the core body temperature and aid to eliminate the waste products from the body. This type of massage is divided into five categories including solid, soft, moderate, great and aggressive, based on the intensity, speed, duration and techniques of massage.Iranian physicians proposed general body massage or massage of a particular area based on subjective complaints. They recommended specific massages in particular groups including children, pregnant women, the elderly and athletes. In some cases, the effects of these recommendations have been studied in clinical trials.Conclusion: It seems that the major difference between Iranian massage and other styles of massage is special attention of Iranian massage to the individual circumstances, and the cause of the problem rather than technique of the massage.

    Full Text Available This study investigates the level of Narcissism among 185 Iranian auditors groups and narcissism has been used to describe people behavior in people groups. The present study uses a questionnaire to measure Narcissism and to examine the hypotheses of the paper analysis of variance and T-test are used. The results of testing hypotheses show that the level of narcissism was significantly different in auditors groups in private sector. However, in public sector, the difference between narcissistic personality in auditors’ groups is not significant. Results of the study also indicated that, in private sector, narcissistic personality in young generation of auditors was higher than audit old generation. These results confirm previous studies on narcissism indicating that narcissistic behavior was high among young generation. We suggest the Iranian association of certified public accountants (IACPA to review the ethical training needs for auditors. In addition, audit firms can provide a system to increase interaction among old generations of auditors with young generation of auditors.

    Dall’s sheep in northwestern Alaska declined in the early 1990s following the severe 1989-90 and 1990-91 winters. In the Baird Mountains of Noatak National Preserve, estimates of adult sheep declined by 50% from 800 in 1989 to under 400 in 1991. Population counts remained low throughout 1991 to 1996, reaching a minimum of 244 adult sheep in 1996. Few lambs were observed during annual midsummer aerial surveys in 1991 to 1994. We suspect that these declines resulted from a combination of poorer nutritional condition and increased vulnerability of sheep to predation resulting from severe winter conditions.As a result of these declines, both subsistence and sport hunting seasons were closed by emergency order in 1991, resulting in substantial management controversy. The affected publics, although willing to accept the closures, questioned the validity of the sheep survey data and strongly emphasized their interest in restoring harvests as soon as populations increased sufficiently. In 1995 the Northwest Arctic Regional Advisory Council, the local advisory committee for the Federal Subsistence Board, passed a motion supporting efforts to initiate research on sheep populations in the region to better understand the factors limiting sheep populations and to evaluate sheep survey methodologies.Currently estimates of Dall’s sheep population size and composition in the western Brooks Range are based on intensive fixed-wing aerial surveys conducted annually since 1986 in areas including the Baird Mountains. The annual variation in recent Baird Mountains aerial counts cannot be explained with reasonable assumptions about reproduction and survival, suggesting that there is some variability in the proportion of the population observed each year or that a substantial number of sheep move during the survey. Prior to our research, no attempt had been made to estimate visibility bias or precision for these surveys.Our understanding of Dall’s sheep population biology comes

    The diversity of populations in domestic species offers great opportunities to study genome response to selection. The recently published Sheep HapMap dataset is a great example of characterization of the world wide genetic diversity in sheep. In this study, we re-analyzed the Sheep HapMap dataset to identify selection signatures in worldwide sheep populations. Compared to previous analyses, we made use of statistical methods that (i) take account of the hierarchical structure of sheep populations, (ii) make use of linkage disequilibrium information and (iii) focus specifically on either recent or older selection signatures. We show that this allows pinpointing several new selection signatures in the sheep genome and distinguishing those related to modern breeding objectives and to earlier post-domestication constraints. The newly identified regions, together with the ones previously identified, reveal the extensive genome response to selection on morphology, color and adaptation to new environments.

  1. ORGANIC PRODUCTION OF SHEEP MILK

    2014-04-01

    Full Text Available Organic production systems are based on natural processes, leveraging local resources and decreasing in soil degradation. Effectiveness of milk production of organic systems vs. conventional production systems is a subject open to debate. There are various studies in which there is a positive effect of organic systems in relation to the welfare and animal health, product quality and environmental impact. However, some authors report lower milk yields production and increased susceptibility to environmental conditions compared with those obtained in conventional systems. The lower milk yields in organic systems in Dairy sheep's production, are related to the limited nutritional value, low genetic potential, and the changing environmental conditions. These systems are mainly a production method for a specific market with premium quality products and high standards in their production processes. Thus, a company organic Dairy sheep production should be considered viable when present a positive global sustainability level, that is socially beneficial, economically viable and environmentally responsible.

    Scrapie is a small ruminant, transmissible spongiform encephalopathy (TSE). Although in the past scrapie has not been considered a zoonosis, the emergence of bovine spongiform encephalopathy, transmissible to humans and experimentally to sheep, indicates that risk exists for small ruminant TSEs in humans. To identify the risk factors for introducing scrapie into sheep flocks, a case-control study was conducted in France from 1999 to 2000. Ninety-four case and 350 control flocks were matched by location and main breed. Three main hypotheses were tested: direct contact between flocks, indirect environmental contact, and foodborne risk. Statistical analysis was performed by using adjusted generalized linear models with the complementary log-log link function, considering flock size as an offset. A notable effect of using proprietary concentrates and milk replacers was observed. The risk was heterogeneous among feed factories. Contacts between flocks were not shown to be a risk factor.

    The number of Iranian immigrants in Canada has been increasing since 1979. This study is the result of a review of 111 charts of Iranian patients who were referred for psychiatric treatment between 1985 and 1988. Ninety-eight percent of them arrived in Canada after the Iranian revolution, which started in 1979, and the Iran-Iraq war of 1980. Ten percent were experiencing trauma as a result of their involvement with the revolutionary government or the war. The symptoms were in accordance with the DSM-III-R criteria for post-traumatic stress disorder. Sixty percent met the criteria for adjustment disorder with depressed or anxious mood. Six percent had been subjected to physical and psychological torture and confinement. This is the first study that looks at the prevalence of psychiatric illness among Iranians and illustrates the effect of migration and displacement in the integrity of the psychic life of this population.

    Full Text Available Tehran as a symbol of Iranian modernity has been considered in many Iranian fiction films. Representation of Tehran in cinema can be the representation of Iranian modernity revolution. This study focuses on the representation of urban image in Iranian fiction films through critical theories such as Simmel or Benjamin opinions. In this article we discus about the mediator role of cinema for representing the Urban life Image and confliction of modernity in Iran.Meanwhile some megalopolis such as Paris, Berlin, Moscow, New York and sanpitersboorg est.…have had great opportunity for understanding confliction of modernity in their situation, Tehran has never have that chance. Regarding to this vacuum we want to explain the role of Iranian fiction films for understanding the entrance of modernity consequences in different eras. We believed that fiction films can represent confliction of city and village, represent of modern dualities, non cohesive rationality and many other gaps in Iranian modernity that we have to know.

    Full Text Available Brucellosis is one of the most important zoonotic diseases and is a significant cause of abortion in animals. Brucella melitensis strain Rev. 1 is recommended as the most effective vaccine for small ruminants but the application of full doses in adult animals is restricted. This study was conducted to determine a proper reduced dose of vaccine which confers protection but which is not abortifacient in Iranian fat-tailed sheep. A total of 51 non-vaccinated pregnant ewes were divided into three main groups and several subgroups. Ewes in different groups were vaccinated at different stages of pregnancy and various subgroups were subcutaneously immunised with different quantities of the micro-organism (7.5 × 106, 106, 5 × 105. Ewes again became pregnant a year later and were challenged with the wild-type strain to evaluate the protection conferred. Results revealed that the proportion of vaccination-induced abortions was significantly higher in ewes immunised with 7.5 × 106 Rev. 1 organisms than in those which received 106 or 5 × 105 bacteria. While 80% of non-vaccinated ewes aborted after challenge, none of the vaccinated ewes aborted post-challenge. This study indicated that a reduced dose of Rev. 1 vaccine containing 106 or 5 × 105 live cells could be safely used to induce protection in Iranian fat-tailed sheep at various stages of pregnancy.

    Full Text Available Introduction: Policies of the Fifth Five-year Socio Economic Development Plan on Iran emphasize on improving factors such as air quality and food security, reduction of the risks and infections that threatens health as well as to change dietary patterns by improving food composition and safety. To this end, the government required to support measures to increase production of animal protein obtained from livestock and poultry. The Iranian targeted subsidy plan started in 2010 which increased energy prices significantly. The increase in energy price after start of targeted subsidies included gasoline (3.6-6.2 times, Kerosene (5.4 times, gas oil (8.1-18.9 and fuel oil (18.8. In terms of supply of animal protein, meat has an important role in nutrition and a major share in family food expenditure so that the willingness to consume it has been obvious in the country's consumer culture. On the other hand, according to international standards, every individual needs 70 grams of protein a day (for average body weight of 70 kg. About one-quarter of this amount (about 25 g should be animal protein. With commence the second phase of a targeted subsidy plan, it is important to get familiar with the effects of this policy on the livestock and poultry industry. A change in livestock prices due to increased production and transport costs have increased the consumer price and have led to changes in the intake of animal protein and calories. With introduction of this plan and recognition of its need in the country, there has been a need to investigate the effects of increasing energy prices on the livestock and poultry industries and to quantify the effects of these policies. This study is trying to investigate the effects of the increase in energy prices for beef, sheep and poultry meat prices, including on a farm and retail prices under various scenarios, the amount of demand and supply and ultimately the effects on food security in Iran.

    Infectious disease was an important driver of historic declines and extirpations of bighorn sheep (Ovis canadensis) in North America and continues to impede population restoration and management. Domestic sheep have long been linked to pneumonia outbreaks in bighorn sheep and this association has now been confirmed in 13 captive commingling experiments. However, ecological and etiological complexities still hinder our understanding and control of the disease. We provide an overview of the current state of knowledge about the biology and management of respiratory disease in bighorn sheep and propose strategies for moving forward. Epizootic pneumonia in bighorn sheep is polymicrobial. Mycoplasma ovipneumoniae, a bacterium host-specific to Caprinae and commonly carried by healthy domestic sheep and goats appears to be a necessary primary agent. All-age epizootics following introduction of M. ovipneumoniae along with other pathogens into bighorn sheep populations are usually severe (median mortality 47%) but fatality rates vary widely, from 15 – 100%. Disease severity may be influenced by the strain of M. ovipneumoniae, by secondary bacterial and viral pathogens, and by factors affecting transmission and host immunity. Once introduced, M. ovipneumoniae can persist in bighorn sheep populations for decades. Carrier dams transmit the pathogen to their susceptible lambs, triggering fatal pneumonia outbreaks in nursery groups, which limits recruitment and slows or prevents population recovery. The result is that demographic costs of pathogen persistence often outweigh the impacts of the initial invasion and die-off. There is currently no effective vaccine or antibiotic for domestic or wild sheep and to date, no management actions have been successful in reducing morbidity, mortality, or disease spread once pathogen invasion has occurred. Molecular-based strain typing suggests that spillover of M. ovipneumoniae into bighorn sheep populations from domestic small ruminants

    The prevalence and phenotypic variability of Pasteurella and Mannheimia isolates from Sierra Nevada bighorn sheep (Ovis canadensis sierrae), White Mountain bighorn sheep (Ovis canadensis nelsoni), and domestic sheep (Ovis aries) from California, USA, were compared. The White Mountain bighorn sheep population had a recent history of pneumonia-associated mortality, whereas the Sierra Nevada bighorn sheep population had no recent history of pneumonia-associated mortality. The domestic sheep flocks were pastured in areas geographically near both populations but were not known to have direct contact with either bighorn sheep population. Oropharyngeal swab samples were collected from healthy domestic and bighorn sheep and cultured to characterize bacterial species, hemolysis, biogroups, and biovariants. Pasteurella trehalosi and Mannheimia haemolytica were detected in all of the study populations, but the relative proportion of each bacterial species differed among sheep populations. Pasteurella trehalosi was more common than M. haemolytica in the bighorn sheep populations, whereas the opposite was true in domestic sheep. Mannheimia haemolytica was separated into 11 biogroups, and P. trehalosi was characterized into two biogroups. Biogroup distributions for M. haemolytica and P. trehalosi differed among the three populations; however, no difference was detected for the distribution of P. trehalosi biogroups between the Sierra Nevada bighorn sheep and domestic sheep. The prevalence odds ratios (pOR) for the distribution of M. haemolytica biogroups suggested little difference between White Mountain bighorn sheep and domestic sheep compared with Sierra Nevada bighorn sheep and domestic sheep, although these comparisons had relatively large confidence intervals for the point estimates. Hemolytic activity of the isolates was not different among the sheep populations for M. haemolytica but was different for P. trehalosi. No clear evidence of association was found in the

    Abstract Respiratory disease and poor lamb recruitment have been identified as limiting factors for bighorn-sheep populations. Haemophilus somnus (recently reclassified as Histophilus somni) is associated with respiratory disease in American bison, domestic sheep, and cattle. It is also harbored in their reproductive tracts and has been associated with reproductive failure in domestic sheep and cattle. Therefore, reproductive tract and lung samples from bighorn sheep were evaluated for the presence of this organism. Organisms identified as H. somnus were isolated from 6 of 62 vaginal but none of 12 preputial swab samples. Antigen specific to H. somnus was detected by immunohistochemical study in 4 of 12 formalin-fixed lung tissue samples of bighorn sheep that died with evidence of pneumonia. Notably, H. somnus was found in alveolar debris in areas of inflammation. The 6 vaginal isolates and 2 H. somnus isolates previously cultured from pneumonic lungs of bighorn sheep were compared with 3 representative isolates from domestic sheep and 2 from cattle. The profiles of major outer membrane proteins and antigens for all of the isolates were predominantly similar, although differences that may be associated with the host–parasite relationship and virulence were detected. The DNA restriction fragment length profiles of the bighorn-sheep isolates had similarities not shared with the other isolates, suggesting distinct phylogenetic lines. All of the isolates had similar antimicrobial profiles, but the isolates from the bighorn sheep produced less pigment than those from the domestic livestock, and growth of the former was not enhanced by CO2. Wildlife biologists and diagnosticians should be aware of the potential of these organisms to cause disease in bighorn sheep and of growth characteristics that may hinder laboratory detection.

    Full Text Available Aims Heavy metals in the environment are toxic to plants, animals and human. This study aimed to investigate concentration of Arsenic, Lead and Cadmium in Iranian and non- Iranian rice which have been sold in Kashan City, Iran shops. Materials & Methods In this cross-sectional study, 126 samples from 42 trademarks (15 Iranian and 27 non-Iranian rice were collected from Kashan shopping centers. At first each sample was ashed, and then they have been dissolved with nitric acid. Heavy metal concentration was evaluated by inductively coupled plasma emission spectrophotometer. Data were analyzed by SPSS 16 software using One-sample and Independent T-tests. Findings Arsenic was not found in any of rice samples. There was a significant difference between Pb concentration in both Iranian and non-Iranian rice samples. There was not a significance difference between Cd concentration in Iranian (p=0.823 and non-Iranian (p=0.346 rice samples according to Iran national standards but there was a significant difference between Cd concentration in both Iranian (p=0.001 and non-Iranian (p=0.001 rice samples according to WHO and FAO standards. Conclusion Consumed rice pollution with Pb is considerable but with Cd is low. Arsenic concentration in Iranian and non-Iranian rice is less than Iran national and WHO/FAO standards.

    Intensive care units (ICUs) provides intensive treatment medicine to avoid complications such as malnutrition, infection and even death. As very little is currently known about the nutritional practices in Iranian ICUs, this study attempted to assess the various aspects of current nutrition support practices in Iranian ICUs. We conducted a cross-sectional study on 150 critically ill patients at 18 ICUs in 12 hospitals located in 2 provinces of Iran from February 2015 to March 2016. Data were collected through interview with supervisors of ICUs, medical record reviews and direct observation of patients during feeding. Our study showed that hospital-prepared enteral tube feeding formulas are the main formulas used in Iranian hospitals. None of the dietitians worked exclusively an ICU and only 30% of patients received diet counselling. Regular monitoring of nutritional status, daily energy and protein intake were not recorded in any of the participating ICUs. Patients were not monitored for anthropometric measurements such as mid-arm circumference (MAC) and electrolyte status. The nasogastric tube was not switched to percutaneous endoscopic gastrostomy or jejunostomy (PEG/PEGJ) in approximately 85% of patients receiving long-term enteral nutrition (EN) support. Our findings demonstrated that the quality of nutritional care was inappropriate in Iranian ICUs and improvement of nutritional care services within Iranian ICUs is necessary. PMID:29713622

    Survival records from 1,763 Kermani lambs born between 1996 and 2004 from 294 ewes and 81 rams were used to determine genetic and non-genetic factors affecting lamb survival. Traits included were lamb survival across five periods from birth to 7, 14, 56, 70, and 90 days of age. Traits were analyzed under Weibull proportional hazard sire models. Several binary analyses were also conducted using animal models. Statistical models included the fixed class effects of sex of lamb, month and year of birth, a covariate effect of birth weight, and random genetic effects of both sire (in survival analyses) and animal (in binary analyses). The average survival to 90 days of age was 94.8%. Hazard rates ranged from 1.00 (birth to 90 days of age) to 1.73 (birth to 7 days of age) between the two sexes indicating that male lambs were at higher risk of mortality than females (P lamb survival and lamb birth weight, suggesting that viability and birth weight could be considered simultaneously in the selection programs to obtain optimal birth weight in Kermani lambs. Estimates of heritabilities from survival analyses were medium and ranged from 0.23 to 0.29. In addition, heritability estimates obtained from binary analyses were low and varied from 0.04 to 0.09. The results of this study suggest that progress in survival traits could be possible through managerial strategies and genetic selection.

    With the coming shortage of fossil fuels it is important to develop energy efficient buildings to reduce both energy consumption and pollution at the same time. In Iran, traditional homes have been built in a sustainable manner to withstand the high climate diversity of the country. The aim of this paper is to present the different methods used in Iranian traditional architecture. Among the architectural principles is appropriate orientation of the building to allow the capture of solar energy and at the same time protect against the cold wind. In addition, indigenous materials were used in the constructions to provide the highest degree of comfort possible with minimal damage to the environment. Finally, Iranian traditional architecture took advantage of the soil's constant temperature by building a Shvadan which is an underground space beneath the house. This article highlighted the different Iranian traditional methods which can create a sustainable architecture.

    Transsexuality in Iran has gained much attention and media coverage in the past few years, particularly in its questionable depiction as a permitted loophole for homosexuality, which is prohibited under Iran's Islamic-inspired legal system. Of course, attention in the West is also encouraged by the “shock” that sex change is available in Iran, a country that Western media and society delights in portraying as monolithically repressive. As a result, Iranian filmmakers inevitably have their own agendas, which are unsurprisingly brought into the film making process—from a desire to sell a product that will appeal to the Western market, to films that endorse specific socio-political agendas. This paper is an attempt to situate sex change and representations of sex change in Iran within a wider theoretical framework than the frequently reiterated conflation with homosexuality, and to open and engage with a wider debate concerning transsexuality in Iran, as well as to specifically analyze the representation of transexuality, in view of its current prominent presence in media.

    Full Text Available Introduction: Head circumference (HC measurement is one of the important parameter for diagnosis of neurological, developmental disorders and dysmorphic syndromes. Recognition of different disorders requires an understanding of normal variation for HC size, in particular, in infancy period with most rapid growth of the brain. Because of international and interracial standard chart differences about anthropometric indices, some differences from local to local, generation to generation and changes in ethnic mix of population and socioeconomic factors, periodic revolution of HC size is suggested. The aims of our study were presenting local HC standard for an Iranian infant population and comparison with the American national center of health statistics (NCHS charts accepted by WHO. Methods: 1003 subjects aged from birth to 24 months apparently healthy normal children enrolled randomly in this cross sectional study. HC size were measured and recorded. Tables and graphs were depicted by Excel Microsoft Office 2007. We use two tailed t-student test for statistical analysis. Results: The mean of HC size in boys was larger than girls. The curves were followed a similar pattern to NCHS based on a visual comparison. Overall our subjects in both sexes at birth time had smaller HC size than NCHS. In other ages our children had larger HC size than those of NCHS. Conclusion: Because of international and interracial difference of HC size. We recommend in each area of the world, local anthropometric indices are constructed and used clinically. In addition more extensive and longitudinally design comprehensive studies is suggested.

    One of the main elements of economic sanctions against Iran due to its nuclear and military programs is crude oil exportation restrictions in addition to investment in Iranian energy related projects. Senders of such sanction are interested in understanding the impacts of such embargos on international oil prices. We apply unrestricted vector autoregressive (VAR) model, using impulse response functions (IRF) and variance decomposition analysis (VDA) tools with annual data from 1965 to 2012 to analyze the dynamic response of international oil prices to Iranian oil export sanction. Controlling for the supply of non-Iranian oil, the world GDP per capita, and post-Islamic revolution exogenous dummy variables, we show that international oil prices respond negatively and statistically significant to increasing shock in absolute negative changes of the Iranian oil exports – our proxy of Iran oil sanctions – following the first 2 years after shock. The main reason is the positive response of the non-Iranian oil supply to negative shocks in Iranian oil exports, filling the missing supply of Iranian oil in international markets. - Highlights: • We analyze the interconnections between Iranian oil supply and global oil prices. • We use VAR modeling and annual data from 1965 to 2012 for the case of Iran. • There are no inflationary effects of Iranian oil sanction on world oil prices. • Non-Iranian oil supply offsets the missing Iranian oil in the market

    Full Text Available ABSTRACT The aim of this work was to develop frozen yogurt formulations from powdered yogurt of sheep milk, through an experimental design of 2², with a triplicate at the central point. The variables studied were emulsifier/stabilizer (0.50%, 0.75%, and 1.00% and powder for cream (2.75%, 3.00% and 3.25%. The parameters evaluated were sensory characteristics, texture, and microbiological counts. The results showed that the formulations had counts of S. aureus and fecal coliforms at 45 °C, lactic acid bacteria and Salmonella sp within the limits established by legislation. Instrumental analysis of texture-related parameters (firmness, cohesiveness, adhesiveness, and consistency of the formulations with different concentrations of emulsifier/stabilizer and cream powder showed no significant differences (p > 0.05. In sensory analysis, Formulations 3 and 4 with lower concentrations of emulsifier/stabilizer scored the highest values, thus indicating good acceptability.

    2012-11-01

    Full Text Available It is well known that the susceptibility of sheep to scrapie is determined by the host’s prion protein gene (PRNP. PRNP polymorphisms at codons 136 (alanine, A/valine, V, 154 (histidine, H/arginine, R and 171 (glutamine, Q/histidine, H/arginine, R are the main determinants of sheep susceptibility/resistance to classical scrapie. There are four major variants of the wild-type ARQ allele: VRQ, AHQ, ARH and ARR. Breeding programs have been developed in the European Union and the USA to increase the frequency of the resistant ARR allele while decreasing the frequency of the susceptible VRQ allele in sheep populations. In Brazil, little PRNP genotyping data are available for sheep, and thus far, no controlled breeding scheme for scrapie has been implemented. This review will focus on important epidemiological aspects of scrapie and the use of genetic resistance as a tool in breeding programs to control the disease.

    1992-09-01

    Iranians express dysphoria through an undifferentiated term called narahati, meaning depressed, ill at ease, nervous, inconvenienced, or anxious. People try masking this emotion or express it in specific ways nonverbally, such as sulking or not eating. Two other dysphoric affects, sadness and anger, are not masked. Because of the social conception of persons being emotionally sensitive, the expression of narahati is guarded: expressing it not only could show that one is socially vulnerable, it could also make another sensitive empathic person narahat. The body is also sensitive, but to the physical world. Physical health is maintained by balancing a diet of "hot" and "cold" foods and avoiding exposure to cold and moisture. With the social and cultural problems brought on by revolution, war, immigration, and accommodation to a new society, Iranian refugees experience changes in family, role, status, finances, language, and other sociocultural ways of being that cause them to feel narahat and to express it verbally, nonverbally, or through somatization. Understanding Iranian conceptions of emotional and physical sensitivity will help clinicians in treating Iranian patients.

    Organizational Citizenship Behavior (OCB) is defined as "individual behavior that is discretionary, not directly or explicitly recognized by the formal reward system, and that in the aggregate, promotes the effective functioning of organization". OCB, enhance job satisfaction among nursing employees. According to several findings, nurses' OCB have a positive and significant influence on job satisfaction. This research is aimed to study OCB among Iranian nurses. A cross-sectional, descriptive and analytical study was conducted among 510 nurses working in 15 teaching hospitals in Tehran, Iran to be selected by stratified random sampling. The respondents were asked to complete Netemeyer's organizational citizenship behavior questionnaire that encompassed four dimensions of OCB including Sportsmanship, Civil Virtue, Conscientiousness, Altruism and selected each item of OCB dimensions and identified their attitudes about OCB items were observed in hospitals of Tehran. The data was analyzed by T-test, ANOVA and Pearson statistical methods. The results of this research showed that most of the nurses who studied in this study, had OCB behaviors. Also, we found that there was significant correlation between Iranian nurses' marriage status, qualifications and gender with sportsmanship, altruism and civic virtue. This research demonstrates the existence of OCB among Iranian nurses that are essential in developing patient - oriented behavior. The results can be used to develop further nursing management strategies for enhancement of OCB. Finally, the present study indicates new possibilities for future researches such as analysis and comparison of OCB between different hospitals and how nursing policy-makers can enhance these behaviors in Iranian hospitals.

    2011-01-01

    Full Text Available The livestock sector of Sudan provides livelihood for about 17% of the population. Sudanese livestock products meet the domestic demand for meat in addition to a substantial excess for export amounting to about 22% of total country exports. It contributes about 19% of GDP. Sheep marketing in Sudan is characterised by traditional operations and is informally organised, although, recently there are great efforts by the formal livestock authorities to organise some secondary and terminal livestock markets. These markets are deficient in basic infrastructures and systematic marketing research. The system as a whole is faced by various complex obstacles and constraints, which decrease the contribution of livestock in general, and sheep in particular, to the national economy, and suppress the optimum exploitation of this resource. These obstacles are represented in the lack of transportation networks that connect the production and consumption centres to break the seasonality of supply that creates shortages and high prices at the consumption centres. This paper employs the policy analysis matrix (PAM technique to examine the Sudanese live sheep and mutton competitiveness in the international market. The results indicated that the market price was greater than the border price implying a positive incentive as an implicit subsidy to the live sheep exporter. The mutton exporters were found subsidised as well. The international value added (IVA indicted a positive foreign exchange earnings or savings. Exported live sheep and mutton coefficient of competitiveness (CIC implied that sheep and mutton exports are profitable and internationally competitive.

    Full Text Available We studied fertility indices of Iranian and non-Iranian populations which were covered by 23 Rays health houses. This cross-sectional study aimed to prove the effect of increasing number of non-Iranian immigrants on health indices of the area covered by Tehran university of medical sciences and health services, consequently giving attention to specific health programs. The data collection method was census of permanent residents of the villages by means of vital horoscopes. 8494 of 27611 persons were non-Iranian. Dependency ratio and natural growth rate was 75%, 1.14% in Iranians and 98%, 1.74% in non-Iranians, respectively. Mortality in non-Iranians was 1.24 times more than Iranians. General fertility rate in Iranians was 60 and in non-Iranians was 110 live births in 1000 women of child bearing age. Total fertility rate in Iranians was 1.73 and in non-Iranians 3.27 neonates for each woman. Age-specific fertility rates were absolutely higher in non-Iranians.

    2011-12-01

    In order to assess and identify the determinants of sheep price and price variation across time, a time series data were collected from four selected markets in North Shewa, Northeastern Ethiopia on weekly market day basis for a period of 2 years. Data on animal characteristics and purpose of buying were collected on a weekly basis from randomly selected 15-25 animals, and a total of 7,976 transactions were recorded. A general linear model technique was used to identify factors influencing sheep price, and the results showed that sheep price (liveweight sheep price per kilogram taken as a dependent variable) is affected by animal characteristics such as weight, sex, age, condition, season, and color. Most of the markets' purpose for which the animal was purchased did not affect significantly the price per kilogram. This may be due to the similarity of the markets in terms of buyer's purpose. The results suggest that there will be benefit from coordinated fattening, breeding, and marketing programs to take the highest advantage from the preferred animals' characteristics and selected festival markets. Finally, the study recommends for a coordinated action to enhance the benefit generated for all participant actors in the sheep value chain through raising sheep productivity, improving the capacity of sheep producers and agribusiness entrepreneurs to access and use latest knowledge and technologies; and strengthening linkages among actors in the sheep value chain.

  8. Change in genetic size of small-closed populations: lessons from a domestic mammal population

    Farhad Ghafouri-Kesbi

    2010-01-01

    Full Text Available The aim of this study was to monitor changes in genetic size of a small-closed population of Iranian Zandi sheep, by using pedigree information from animals born between 1991 and 2005. The genetic size was assessed by using measures based on the probability of identity-by-descend of genes (coancestry, f, and effective population size, Ne, as well as measures based on probability of gene origin (effective number of founders, f e, effective number of founder genomes, f g, and effective number of non-founder genomes, f ne. Average coancestry, or the degree of genetic similarity of individuals, increased from 0.81% to 1.44% during the period 1993 to 2005, at the same time that Ne decreased from 263 to 93. The observed trend for f e was irregular throughout the experiment in a way that f e was 68, 87, 77, 92, and 80 in 1993, 1996, 1999, 2002, and 2005, respectively. Simultaneously, f g, the most informative effective number, decreased from 61 to 35. The index of genetic diversity (GD which was obtained from estimates of f g,decreased about 2% throughout the period studied. In addition, a noticeable reduction was observed in the estimates of f ne from 595 in 1993 to 61 in 2005. The higher than 1 ratio of f e to f g indicated the presence of bottlenecks and genetic drift in the development of this population of Zandi sheep. From 1993 to 1999, f ne was much higher than f e, thereby indicating that with respect to loss of genetic diversity, the unequal contribution of founders was more important than the random genetic drift in non-founder generations. Subsequently, random genetic drift in non-founder generations was the major reason for f e> f ne. The minimization of average coancestry in new reproductive individuals was recommended as a means of preserving the population against a further loss in genetic diversity.

    2007-11-01

    Breeding objectives were developed for Targhee sheep under rangeland production conditions. Traits considered were those for which EPD were available from the US National Sheep Improvement Program and included direct and maternal effects on 120-d weaning weight (WW and MM, respectively); yearling weight (YW); yearling fleece weight, fiber diameter, and staple length; and percent lamb crop (PLC), measured as the number of lambs born per 100 ewes lambing. A bioeconomic model was used to predict the effects of a change of 1 additive SD in EPD for each trait, holding all other traits constant at their mean, on animal performance, feed requirements, feed costs, and economic returns. Resulting economic weightings were then used to derive selection indexes. Indexes were derived separately for 3 prolificacy levels (1.41, 1.55, and 1.70 lambs/ewe lambing), 2 triplet survival levels (50 and 67%), 2 lamb pricing policies (with or without discounting of prices for heavy feeder lambs), and 3 forage cost scenarios (renting pasture, purchasing hay, or reducing flock size to accommodate increased nutrient requirements for production). Increasing PLC generally had the largest impact on profitability, although an increase in WW was equally important, with low feed costs and no discounting of prices for heavy feeder lambs. Increases in PLC were recommended at all 3 prolificacy levels, but with low triplet survival the value of increasing PLC eventually declined as the mean litter size increased to approximately 2.15 lambs/ewe lambing and above. Increasing YW (independent of WW) increased ewe maintenance costs and reduced profitability. Predicted changes in breeding values for WW and YW under index selection varied with lamb pricing policy and feed costs. With low feed costs or no discounts for heavy lambs, YW increased at a modest rate in association with increasing WW, but with high feed costs or discounting of heavy lambs, genetic trends in WW were reduced by approximately 50% to

    We have determined the most suitable method for the automated analysis of the clotting parameters in sheep intestinal and prefemoral lymph as defined by the Activated Partial Thromboplastin Times (APTT; measure of intrinsic coagulation pathway) and the Prothrombin Times (PT; measure of extrinsic coagulation pathway). As opposed to optical density systems, the use of a Fibro-System Fibrometer was found to provide the most consistent assessment of coagulation with the endpoint being the time to fibrin strand formation. We measured APTT in sheep intestinal and prefemoral lymph of 59.78 +/- 7.69 seconds and 51.03 +/- 10.49 seconds respectively. These values were more prolonged than those obtained from sheep blood plasma but only in the case of intestinal lymph were the differences significant (p less than 0.025). Human blood APTT values were significantly less than both sheep blood (p less than 0.05) and sheep intestinal (p less than 0.001) and prefemoral lymph (p less than 0.01). PT values were found to be 21.56 +/- 1.14 seconds in intestinal and 22.00 +/- 1.88 seconds in prefemoral lymph. These values were also significantly greater than those obtained from sheep blood (both p less than 0.001). Human blood PTs were significantly less than both sheep blood (p less than 0.001) and intestinal and prefemoral lymph (both p less than 0.001). Measurement of APTT and PT values in intestinal lymph and PT determinations in prefemoral lymph were not affected by storage in the refrigerator or freezer. There was some indication that APTT values in prefemoral samples were susceptible to storage artifacts; however, the differences in coagulation times were not significant.

    Full Text Available The purposes of the present study were morphometric characterization of rostellar hooks of Taenia multiceps and to investigate the association of hook length variation and the variability within two mitochondrial genes of sheep isolates of the parasite.Up to 4500 sheep brains were examined for the presence of C. cerebralis. Biometric characters based on the larval rostellar hook size were measured for each individual isolate. Representative mitochondrial CO1 and 12S rRNA gene sequences for each of the isolates were obtained from NCBI GenBank. Morphometric and genetic data were analyzed using cluster analysis, Interclass Correlation Coefficient (ICC and random effects model.One hundred and fourteen sheep (2.5% were found infected with the coenuri. The minimum and maximum number of scoleces per cyst was 40 and 550 respectively. Each scolex contained 22-27 hooks arranged in two rows of large and small hooks. The average total length of the large and small hooks was 158.9 and 112.1 μm, respectively. Using ICC, statistically significant clusters of different hook sizes were identified within the isolates. The length of the large and small hooks was significantly associated with the variability in mitochondrial 12S rRNA gene.Taenia multiceps, is a relatively important zoonotic infection in Iranian sheep with the prevalence rate of 2.5%. Hook length analysis revealed statistically significant difference among individual isolates. Associations between the rostellar hook length and variability in the mitochondrial 12S rRNA was documented.

    Full Text Available The objective of this study was to establish the impact of crossing the indigenous Cres sheep with Awassi and, respectively, Awassi and East Friesian sheep on the milk yield and quality. For this purpose, through regular monthly milk yield recordings a total of 824individual milk samples from 139 sheep in the second lactation of the same flock were collected, of which: 46 purebred Cres sheep, CS; 33 crosses with 50 % Cres sheep and 50 % Awassi, CA; 60 crosses with 50 % Cres sheep, 25 % Awassi and 25 % East Friesian, CAEF. The obtained results show a significant (P<0.05; P<0.01 impact of the genotype and the lactation stage on the yield and chemical composition of milk, and the somatic cell count. The most milk was yielded by CAEF crosses (690 mL/ewe/day, i.e., 133.8 L per lactation and the least by CS (340 mL/ewe/day, i.e., 58.48 L per lactation. The content of total solids, fat and protein increased as lactation advanced, whereas the trend of the lactose content was opposite. The highest content of total solids, fat and protein were established in the milk of the indigenous Cres sheep. A positive correlation was established between the amount of yielded milk and the somatic cell count, whereas a negative correlation was established between the amount of milk and the content of solids, fat and proteins.

    Melophagus ovinus (sheep ked) is one of the most common ectoparasites that contributes to enormous economic losses in the productivity of sheep in many countries. The present study was conducted from January 2012 to July 2013 on M. ovinus collected from sheep at three sites in Ethiopia. Of the sheep studied, 65.7% (88/134) were infested with M. ovinus. The prevalence of M. ovinus was 76% (76/100), 47% (8/17) and 23.5% (4/17) at the Kimbibit, Chacha and Shano sites, respectively. An overall number of 229 M. ovinus specimens (138 females, 86 males and five pupae) and 554 M. ovinus specimens (272 females, 282 males) were collected from young and adult sheep, respectively. Bartonella DNA was detected in 89% (694/783) of M. ovinus using a quantitative Bartonella genus-specific PCR assay targeting the 16S/23S rRNA intergenic spacer region. The sequencing of the PCR products of fragments of the gltA and rpoB genes showed 99.6-100% and 100% homology, respectively, with B. melophagi. Statistically significant variation was not noted in the overall prevalence of Bartonella DNA between female and male M. ovinus. All of the sheep infested with M. ovinus 100% (88/88) harbored at least one M. ovinus specimen that contained Bartonella DNA. This study highlights that B. melophagi in M. ovinus from sheep in highlands in Ethiopia possibly has certain zoonotic importance. Copyright © 2013 Elsevier Ltd. All rights reserved.

In contrary to modern middle-class Iranian high density vertical development housing, this cultural principle plays a great role in shaping spatial organization of Iranian traditional housing. The aim of this study is to establish a framework to improve spatial organization of modern Iranian high density vertical development (HDVD housing through lessons learnt from traditional Iranian housing. In this regard, to reach the aim through qualitative approach and case study strategy, this value of the Iranian traditional housing was investigated. The data collection methods to collect data from middle-class traditional and modern high-density vertical development (HDVD housing, were multiple tactics as direct observation, open-ended expert interview, semi-structured and focus group interviewing, taking photo, and plan layout. As conclude, it was reached that privacy as a principle governing all aspects of life has had deep impacts on spatial organization of traditional Iranian housing. Thus through using the spatial concept of privacy learnt from traditional Iranian housing can formulate recommendations to betterment spatial organization of middle-class modern Iranian HDVD housing.

    To test the hypothesis that Mycoplasma ovipneumoniae is an important agent of the bighorn sheep (Ovis canadensis) pneumonia that has previously inevitably followed experimental commingling with domestic sheep (Ovis aries), we commingled M. ovipneumoniae-free domestic and bighorn sheep (n=4 each). One bighorn sheep died with acute pneumonia 90 days after commingling, but the other three remained healthy for >100 days. This unprecedented survival rate is significantly different (P=0.002) from that of previous bighorn-domestic sheep contact studies but similar to (P>0.05) bighorn sheep survival following commingling with other ungulates. The absence of epizootic respiratory disease in this experiment supports the hypothesized role of M. ovipneumoniae as a key pathogen of epizootic pneumonia in bighorn sheep commingled with domestic sheep.

    Full Text Available Background: A supportive needs assessment is an essential component of any care program. There is no research evidence regarding the supportive care needs of cancer patients in Iran or other Middle Eastern countries. Aims: The aim of this study was to determine the supportive care needs of Iranian cancer patients. Materials and Methods: This descriptive study was conducted in a referral medical center in the northwest of Iran. A total of 274 cancer patients completed the Supportive Care Needs Survey (SCNS-59. Descriptive statistics were used for data analysis. Results: In 18 items of the SCNS, more than 50% of the participants reported that their needs were unmet. Most frequently, unmet needs were related to the health system, information, physical, and daily living domains, and most met needs were related to sexuality, patient care, and support domains. Conclusions: Iranian cancer patients experience many unmet needs and there is an urgent need for establishing additional supportive care services in Iran.

    Consanguineous marriage--marriage between relatives--has received a great deal of attention as a potential risk factor for many adverse health outcomes. The present cross-sectional study was done in order to illustrate the prevalence and types of consanguineous marriages among Iranian Georgians living in Frydoonshahr (Isfahan province, central Iran). Data on consanguineous marriages were collected using a simple questionnaire. The total number of couples in this study was 646. Consanguineous marriage was classified by the degree of relationship between couples. First cousin marriages (14.2%) were the most common type of consanguineous marriages, followed by second cousin (7.0%), beyond second cousin (1.5%) and first cousin once removed (0.6%). The mean inbreeding coefficient (α) was calculated as 0.0104 for the population. The present study shows that the study population, as other Iranian populations, has a high level of consanguinity.

  10. Iranian Political Strategy: Ideology or Pragmatism

    International Nuclear Information System (INIS)

    2008-01-01

    Iranian political strategy wants to be presented as a political break, with a Pan-Islamic vocation. Brought about by Ayatollah Khomeyni, this political philosophy has produced the intended effects, as seen with the return of more moderate policies. Khomeyni's death confronted the Islamic Republic with a choice: Hachemi Rasfandjani put Iran back into the international scene by conciliating pragmatism with ideological values. In 2005, M. Ahmadinejad came to power. His declarations concerning the Hebrew State and his position on nuclear weapons pose the question as to whether or not Iran is reverting to an export policy of revolution. It is important to place these elements in the historical context of the Islamic Republic so as to see if Iranian foreign policy is again taking an ideological turn or if it is continuing down the lane of pragmatism

    Surrogacy is a popular form of assisted reproductive technology of which only gestational form is approved by most of the religious scholars in Iran. Little evidence exists about the Iranian infertile women's viewpoint regarding gestational surrogacy. To assess the viewpoint of Iranian infertile women toward gestational surrogacy. This descriptive study was conducted at the infertility clinic of Tabriz University of Medical Sciences, Iran. The study sample consisted of 238 infertile women who were selected using the eligible sampling method. Data were collected by using a researcher developed questionnaire that included 25 items based on a five-point Likert scale. Data analysis was conducted by SPSS statistical software using descriptive statistics. Viewpoint of 214 women (89.9%) was positive. 36 (15.1%) women considered gestational surrogacy against their religious beliefs; 170 women (71.4%) did not assume the commissioning couple as owners of the baby; 160 women (67.2%) said that children who were born through surrogacy would better not know about it; and 174 women (73.1%) believed that children born through surrogacy will face mental problems. Iranian infertile women have positive viewpoint regarding the surrogacy. However, to increase the acceptability of surrogacy among infertile women, further efforts are needed.

    Herbal distillates have been used as beverages, for flavoring, or as phytomedicines in many countries for a long time. Recently, the occurrence of blindness after drinking herbal distillates has created concerns in Iran. The aim of this study was to determine the concentrations of methanol in herbal distillates produced in Iran. Eighty-four most commonly used herbal distillates purchased from herbal distillate factories were analyzed for methanol contents by gas chromatography and flame ionization detection, with ethanol as internal standard. In 15 herbal distillates, the methanol concentration was below the limit of quantitation. The methanol concentrations in all samples ranged from 43 to 277 mg/L. Forty-five samples contained methanol in excess of the Iranian standard. The maximum concentration was found in an herbal distillate of Mentha piperita (factory E) (277±12), and the minimum in a distillate of Carum carvi (factory B) (42.6 ± 0.5). Since the 45 Iranian herbal distillates containing methanol levels were beyond the legal limits according to the Iranian standard, it seems necessary to monitor the amount of methanol and give a warning to watch out for the latent risk problem of methanol uptake, and establish a definitive relationship between the degree of intoxication observed and the accumulation of methanol in the blood.

    2008-03-01

    Although greater emphasis has been placed on leadership skills in nursing management in the last decade, the concepts are often confused or used erroneously by Iranian nurses. At the same time we have observed that wide variations in nurses' clinical practice appeared to be related to the presence or absence of leadership skills among senior nurses. To begin to identify the concepts used for expressing leadership in nursing within the Iranian cultural context. A qualitative approach was adopted using content analysis of semi-structured interviews carried out with 10 nurse managers from hospitals in Teheran. The data were analysed using the constant comparative method. Fifty-five primary codes were identified from the respondents' experiences and from these three main themes were abstracted for describing the leadership concept. These were 'personality traits', 'being a model', and 'being a spiritual guide for the nursing profession'. Implementing the culture of patient safety and dignity needs leadership. From Iranian nurse managers' perspectives a leader as a spiritual guide should empower nurses spiritually; it means he/she has a vision for nursing; has clear and explicit objectives; and has a commitment to nursing. Nurses who are confident about the underlying concepts of leadership in their culture can help to adapt nursing to an ever-changing healthcare environment.

    Autopsy studies of four Jacob sheep dying within their first 6-8 months of a progressive neurodegenerative disorder suggested the presence of a neuronal storage disease. Lysosomal enzyme studies of brain and liver from an affected animal revealed diminished activity of hexosaminidase A (Hex A) measured with an artificial substrate specific for this component of β-hexosaminidase. Absence of Hex A activity was confirmed by cellulose acetate electrophoresis. Brain lipid analyses demonstrated the presence of increased concentrations of G(M2)-ganglioside and asialo-G(M2)-ganglioside. The hexa cDNA of Jacob sheep was cloned and sequenced revealing an identical number of nucleotides and exons as in human HexA and 86% homology in nucleotide sequence. A missense mutation was found in the hexa cDNA of the affected sheep caused by a single nucleotide change at the end of exon 11 resulting in skipping of exon 11. Transfection of normal sheep hexa cDNA into COS1 cells and human Hex A-deficient cells led to expression of Hex S but no increase in Hex A indicating absence of cross-species dimerization of sheep Hex α-subunit with human Hex β-subunits. Using restriction site analysis, the heterozygote frequency of this mutation in Jacob sheep was determined in three geographically separate flocks to average 14%. This large naturally occurring animal model of Tay-Sachs disease is the first to offer promise as a means for trials of gene therapy applicable to human infants. Copyright © 2010 Elsevier Inc.

    Male sheep of reproductive age were distributed into three groups: GI, a sheep inoculated (oral) with 2.0×10(5) oocysts of the P strain of Toxoplasma gondii; GII, a sheep infected (subcutaneous) with 1.0×10(6) tachyzoites of the RH strain of T. gondii; and GIII, a sheep kept as a control (not infected). After the inoculation of the males, 12 breeding ewes, which were not pregnant and which were serologically negative for reproductive diseases (particularly toxoplasmosis), were distributed into three groups, synchronized, and subsequently exposed to natural mating with previously inoculated males. The distribution was as follows: five ewes that underwent natural mating with the GI male, five ewes that were exposed to natural mating with the GII male, and two ewes that were mated with the non-infected male (control). Serum samples of all the ewes were collected on days -30, -14, -7, -1, and 0 (days before natural mating) and on days 1, 3, 5, 7, 11, 14, and weekly until birth; the presence of serum antibodies against T. gondii was assessed by IFAT. Using a bioassay and PCR, T. gondii was isolated from the semen of the infected reproducing sheep before mating. Following natural mating, 5 of the 12 females displayed antibodies specific for T. gondii; of these animals, two of the ewes underwent natural mating with the male inoculated with oocysts (GI) and three with the male infected with tachyzoites (GII). One of the females that displayed antibodies specific to this coccidian and that underwent natural mating with the GII sheep had a macerated fetus on the 70th day following coverage. Using a bioassay after the birth, it was possible to isolate T. gondii from samples of the "pool" of tissues from the five females that seroconverted after natural mating and from their respective lambs. Using PCR, the DNA of T. gondii was isolated from the "pool" of tissues from one and two females exposed to natural mating with the reproductive males infected with the oocysts and

    Full Text Available ABSTRACT: The processing of Manihot esculenta (cassava tubers yield different by-products, including cassava wastewater, which is the liquid pressed out of the tuber after it has been mechanically crushed. Cyanide poisoning after ingestion of cassava wastewater has been reported in ruminants and pigs in Northeastern Brazil. With the aim of studying its toxicity, cassava wastewater was administered orally to six sheep at doses of 0.99, 0.75, 0.70, 0.63, and 0.5 mg of hydrocyanic acid kg-1 body weight, which corresponded to 14.2, 10.6, 9.8, 8.89, and 7.1 mL of wastewater kg-1. On the second day, the sheep received a volume of wastewater which corresponded to 0.46, 0.34, 0.31, 0.28, and 0.23 mg of HCN kg-1. A sheep used as control received 9.9 mL of water kg-1 BW. Sheep that received from 0.75 to 0.99 mg kg-1 of HCN on the first day exhibited severe clinical signs of poisoning, and the sheep that received 0.63 and 0.5 mg kg-1 exhibited mild clinical signs. All sheep were successfully treated with sodium thiosulfate. On the second day, only the sheep that received 0.46 mg kg-1 and 0.34 mg kg-1 exhibited mild clinical signs and recovered spontaneously. The concentration of HCN in the wastewater was 71.69±2.19 μg mL-1 immediately after production, 30.56±2.45 μg mL-1 after 24 hours, and 24.25±1.28 μg mL-1 after 48 hours. The picric acid paper test was strongly positive 5 minutes after production; moderately positive 24 hours after production, and negative 48 hours after production. We conclude that cassava wastewater is highly toxic to sheep if ingested immediately after production, but rapidly loses toxicity in 24-48 hours.

    Tomov, A

    1964-01-01

    In the period 1961-1962 chronic intoxication of sheep with copper was observed on 7 farms, the number of sheep totaling about 9000. In one of the flocks intoxication occurred after feeding the sheep for a long time with aftermath collected from orchards which had been sprinkled with copper compounds. The aftermath was proven to contain from 11 to 17 mg. per cent of copper. The other flocks were put to pasture in vineyards after the grapes had been gathered. Intoxication in these flocks was caused by vineleaves. No accumulation of copper through the soil was established in the investigated fresh grass found in the vineyards and which the sheep had also grazed. From 36 to 81 mg. per cent of copper was established in the livers of dead sheep. In order to protect the sheep from this intoxication, 100-200 mg. of ammonium or sodium molybdate and 5-10 g. of sodium sulfate were used in the case of each sheep daily for 2-3 weeks. The concentrated fodder of the sheep was moistened with an aqueous solution of these compounds. A very good prophylactic effect was obtained. At the same time oats, maize, oilcakes and others, which constitute a fodder rich in fats, were eliminated from the food rations of the sheep. The above substances, given at larger doses simultaneously with vitamin B/sub 12/ were also used for the treatment of diseased sheep, and of 10 ill sheep, 7 recovered.

    2013-01-01

    Full Text Available The 2009 Iranian Presidential Elections represented one of the most contentious displays of the evolving Iranian democracy since the 1979 Islamic Revolution that led to the removal of Mohammad Reza Shah Pahlavi – the nation’s last shah. This tumultuous political event not only exposed a growing rift between the political and religious ruling elite in that country; it also led to the emergence of an opposition movement that would later be known as the Green Revolution. Viewed through a Western political lens, this revolution represented yet another opportunity for the demise of the ruling Iranian Islamic Regime. Recently, some scholars have questioned whether this movement was ever intended to topple the government in the first place, and have argued instead that it represented the beginning of a long-term civil rights push. To better understand why the Green Movement emerged one must first understand what the original intent of the movement was, as well as the political factors that led to its rapid growth. In order to answer these questions, this article will compare and contrast identified similarities and differences between the 1979 Islamic Revolution and 2009 Green Movement in order to isolate the true intent behind this perceived Iranian political revolt.

    Full Text Available Sheep production is present on all continents and has been practiced in Brazil since the colonization. In this study, the multitemporal dynamics of sheep production in Brazil is examined using official government data (Brazilian Institute for Geography and Statistics-IBGE from 1976 to 2010. Maps of flock growth rates and growth acceleration maps by municipality were elaborated. The Southern states are seen to show a reduction in production mainly due to the wool crisis in the 1970s and 80s. The Northeast is seen to be important for meat production. More recently, centerwest and northern states have shown an increase in growth rates but this is still incipient. The maps of growth, acceleration and midpoint for sheep production showed a noticeable return to an increase in production in the South in recent years. The midpoint of production flow was in the northeast direction, which has stagnated. There was great dynamics in sheep production over the whole Brazilian territory, which affected supply chains due to the expansion of domestic and foreign markets. Areas with higher fluctuations in production are more vulnerable in terms of investment policies.

    2006-01-01

    Sheep are the moving banks of shepherds and their economic contribution in terms of meat, wool and skin/hide is immense. Various infectious diseases jeopardize the optimum productivity; among which sheep pox is more important as the disease restricts the export of sheep and their products besides other economic losses. Although, clinical signs are indicative of the disease but a laboratory confirmation is necessary for unequivocal diagnosis and studying epidemiology. The causative agent, sheep pox virus (SPV), is antigenically and genetically closely related to goat pox virus (GPV) and lumpy skin disease virus (LSDV), the other members of the genus capripox virus. In some countries, SPV and GPV are cross infective to small ruminants posing problem in diagnosis and epidemiology. However, recent studies have showed that the viruses are phylogenetically distinct and can be differentiated by molecular tools. Prophylaxis using attenuated vaccines is the choice of control measure as the immunity is long lasting. Detailed information on isolation, identification, pathology, epidemiology, diagnosis and prophylaxis would not only help in updating the knowledge of scientific fraternity but will be useful to the policy makers in order to formulate appropriate measures for control and eradication of the disease. This synthesis is to present an up-to-date review of the disease and its control to provide the reader with an overview of the problem.

    From 1986 to 1989, 5 desert bighorn sheep (3 Ovis canadensis mexicana and 2 O c nelsoni), ranging in age from 2 to 3 years, were exposed to a flock of exotic wild and domestic sheep to potentially achieve naturally acquired pneumonia. Pasteurella multocida was isolated from nasal samples from 4 of 6 sheep randomly sampled from the flock. Bighorn sheep were exposed individually and each exposure period was a trial. Treatment before and after exposure varied and included combinations of alpha interferon, antibiotics, anti-inflammatory drugs, and vaccines. Treatments were chosen on the basis of recommendations of others for treating pneumonia in desert bighorn sheep as well as our own experience in sheep and cattle. Regardless of treatment used, bighorn sheep in trials 1 to 4 developed signs of pneumonia within 10 to 14 days of exposure. Bighorn sheep in trials 1 to 3 died within 11 to 17 days of initial exposure. In trial 4, the bighorn sheep was isolated from the carrier sheep for treatment of pneumonia on day 14 and died on day 30. Pasteurella multocida was isolated from lung tissue in 3 of the 4 bighorn sheep. On the basis of results of trials 1 to 4, a more in depth clinical study was conducted in trial 5. Nasal and blood specimens were collected prior to and during trial 5 for bacteriologic culturing and serologic testing for bovine viral diarrhea virus, infectious bovine rhinotracheitis, parainfluenza-3 virus, and respiratory syncytial virus.(ABSTRACT TRUNCATED AT 250 WORDS)

  15. Radiocaesium variability in upland sheep flocks

    2002-07-01

    Following the 1986 Chernobyl accident large areas of uplands in the United Kingdom were contaminated by radiocaesium. Consequently, the level of radiocaesium in the tissues of some sheep exceeded 1000 Bq kg{sup -1} fresh weight This is the limit adopted within the UK above which meat cannot enter the food chain. In 1986, restrictions were placed on the movement and slaughter of sheep in areas of west Cumbria, north Wales and Scotland. Whilst the number of farms under restriction has reduced considerably, some still remain restricted in 2002. Although a number of workers had noted considerable variability between the radiocaesium activities of individuals within sheep flocks there had been no analyses of causal effects. The work described here, combined studies on three upland farms within west Cumbria with controlled feeding experiments, to systematically assess the parameters which may contribute to such variability. Results from all three farms demonstrate a temporally consistent ranking of the {sup 137}Cs activity concentration of individual sheep within the study flocks. As there was also a correlation between the {sup 137}Cs activity concentration of ewes and their pre-weaned lambs it is likely that the same ewes are producing lambs in excess of the intervention limit in subsequent years. It is difficult to generalise as to which factors will contribute to {sup 137}Cs variability within a given upland flock; factors contributing to variation were not consistent between the study farms. However, the location grazed and/or vegetation selected by animals was a causal factor to the observed variability at all three farms. The transfer of radiocaesium from the diet to muscle of sheep was found to be determined by live-weight change and dry matter intake. Subsequent studies have suggested that protein turnover may be a potential mechanism for the relationship between dry matter intake and radiocaesium transfer. This hypothesis is supported by current understanding

    The purpose of this study is to analyse Iranian scientific publications in the neuroscience subfields by librarians and neuroscientists, using Science Citation Index Expanded (SCIE) via Web of Science data over the period, 2002-2008. Data were retrieved from the SCIE. Data were collected from the 'subject area' of the database and classified by neuroscience experts into 14 subfields. To identify the citation patterns, we applied the 'impact factor' and the 'number of publication'. Data were also analysed using HISTCITE, Excel 2007 and SPSS. Seven hundred and thirty-four papers have been published by Iranian between 2002 and 2008. Findings showed a growing trend of neuroscience papers in the last 3 years with most papers (264) classified in the neuropharmacology subfield. There were fewer papers in neurohistory, psychopharmacology and artificial intelligence. International contributions of authors were mostly in the neurology subfield, and 'Collaboration Coefficient' for the neuroscience subfields in Iran was 0.686 which is acceptable. Most international collaboration between Iranians and developed countries was from USA. Eighty-seven percent of the published papers were in journals with the impact factor between 0 and 4; 25% of papers were published by the researchers affiliated to Tehran University of Medical Sciences. Progress of neuroscience in Iran is mostly seen in the neuropharmacology and the neurology subfields. Other subfields should also be considered as a research priority by health policymakers. As this study was carried out by the collaboration of librarians and neuroscientists, it has been proved valuable for both librarians and policymakers. This study may be encouraging for librarians from other developing countries. © 2012 The authors. Health Information and Libraries Journal © 2012 Health Libraries Group.

  18. Iranian gas will be an issue

    2008-01-01

    In this paper an interview with director of the Nabucco project, Reinhard Mitchek is published. There is extract from this interview: Iranian gas is a politically sensitive topic Europe cannot avoid I believe that it will become a topic in Europe in the medium to long term. Shouldn't Europe declare that it needs Iranian gas? Otherwise Russia or China may take over. I do not want to advise the European Commission via the media. Iranian gas would bring the Nabucco project closer to reality. A common European Union (EU) foreign policy and common foreign energy policy in particular will be of major importance. We of course need competition in the EU gas sector. But that is a business topic. The political issue is the competitiveness of Europe as an entity competing for energy sources with other regions. The European Union keeps repeating that the Nabucco project has high priority. But what steps has it undertaken to support it? The Commissioner for Energy, Andris Piebalgs, and the Commissioner for External Relations and European Neighbourhood Policy, Benita Ferrero-Waldner, visited Central Asia and supported the export of gas to Europe. That is exactly what Russia does and with more success. We will see. Naturally - these countries have a history of relationships with Russia. Turkmenistan and Kazakhstan have been exporting gas to Russia. But in the meantime these countries also want to extend their export portfolio. We think that through the Trans-Caspian pipeline and the existing gas pipeline connecting Azerbaijan with Turkey, gas from Azerbaijan and Turkmenistan will also get to Nabucco. (authors)

    Full text: The zeolite researches in Iran is a relatively new subject which has started about 10 years ago. The motivation for this scientific and interesting field was provided after discovery of significant deposits of natural zeolites in different regions of Iran as well as further developments of research institutions and the national concern to environmental protection especially the wastewater clean-up in point of view of recycling of such waste water to compensate some needs to water in other utilizations. This paper intends to review and describes scientific researches which have done on using zeolites in the field of nuclear waste treatment in Iran to introduce the potential resources to the world in more details. Zeolite tuffs are widely distributed in huge deposits in different regions of Iran. So far, the clinoptilolite tuffs are the most abundant natural zeolite which exist with zeolite content of 65%- 95%. Nowadays several different types of Iranian natural zeolites are characterized in point of view of chemical composition, type of structure, chemical, thermal, and radiation resistance using different instrumental and classical methods such as; X-ray diffraction (XRD), X-ray fluoresce (XRF), thermal methods of analysis (TA), scanning electron microscopy (SEM), analytical chemistry and radioanalytical methods as well as different ion-exchange techniques (e.g.3-7). The ability of Iranian natural clinoptilolite for removal of some fission products from nuclear wastewaters have been investigated. The selectivity of all investigated zeolites toward radiocesium and radiostrontium have been promising (e.g. 8-10). The successful synthesize of P zeolite from Iranian clinoptilolite-reach tuffs under different conditions were performed. The compatibility of zeolites with glass and cement matrices, for final disposal of radwaste, as well as their selectivity toward most dangerous heat generating radionuclides (e.g. 137 Cs and 90 Sr) is very important in using

    Full Text Available Itineraries have been an important source of knowing cultural and social characteristics of societies, but this has been involved with some limitations in understanding, knowledge and interpretation. In fact, travel diaries are a kind of narrative. This narrative is restricted by time, place, situation and events.This article studies itineraries written by foreigners about Iranians and their cultural – social characters. This narrative has a pathological aspect, being dominant aspect in foreign travel diaries. Certainly, they present a biased and presupposed picture of our history, but they could be very instructive.

  2. Iranians and Their Pride: Modalities of Political Sovereignty

    Moaddel, Mansoor

    In 2000, we asked a nationally representative sample of 2,532 Iranian adults "which of the following best describes you: I am an Iranian, above all; I am a Muslim, above all; I am an Arab, a Kurd, a Turk, a Baluch, etc., above all?" We also asked them how proud they are to be Iranian; (1) very proud, (2) proud, (3) not proud, and (4) not proud at all. In the 2005 survey of a nationally representative sample of 2,667 Iranian adults, we asked these questions again. The first question was intended to measure national identity and the second national pride. The results showed that between the two surveys the percent of Iranians who defined themselves as "Iranians, above all" went up significantly-from 35% in 2000 to 42% in 2005. Those who said that they were very proud to be Iranian, on the other hand, went down considerably-from 89% in 2000 to 64% in 2005. What is more, national identity and national pride displayed opposing relationships with the norms and values that were rigorously promoted by Iran's religious regime and these relationships grew stronger between 2000 and 2005. The feeling of national pride was positively linked to attitudes toward gender inequality, religiosity, and religious intolerance, but negatively to attitudes toward the West, while national identity had just the opposite relationships with these variables.

    Facial anthropometric measurement is considered an essential concern of surgeons, orthodontists, artists and forensic scientists. The aim of this study is to investigate facial anthropometric norms of the young Iranian population. The study participants consisted of 200 healthy Iranian students (100 males, 100 females) aged 18-25 years old. Twenty-three liner and four angular measurements were investigated twice by a dentist. Independent-samples t test was used to compare indices between males and females and also between countries. A p value less than 0.05 was considered statistically significant. It was found that the mean measurements of c'-sn' of both sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were statistically greater in Iranian males than in females ( p  < 0.05). Comparing Iranian anthropometric norms with North American Whites, Malays, Turkish and African American women demonstrated that there were statistically significant differences in most anthropometric measurements between Iranians and other populations ( p  < 0.05). In Iranians, mean measurements of c'-sn' of the right and left sides, nasolabial angle, trichion-gnathion, tragion-tragion and gnathion-gnathion were greater in men than in women. Comparing Iranian males and females with different ethnicities indicated several interracial differences, which should be taken into consideration when dealing with patients or also practitioners originated in this region.

    Scientific journals are the most credible and updated information resources for valid information in the various fields of science and technology. The present study investigates the status of Iranian scientific journals in disseminating medical information to the world of science. Total 163 Iranian medical journals accredited by national medical journals commission of Iranian ministry of health and medical education were evaluated through a cross-sectional study. The results were represented in descriptive statistics in the form of table and chart. The study showed that 89.6% of Iranian medical journals were covered by regional information databases. Web of Science database indexed 22 (13.5%) Iranian journals in the field of medical science. Only six (6.7%) journals were indexed by Medline. Fifty-eight (35.6%) journals were in English, 102 (62.6%) in Persian, and three (1.8%) were bilingual which published their articles both in Persian and English languages. The highest Impact factor belonged to Iranian Journal of Allergy Asthma and Immunology. Improving scientific credibility of Iranian scholarly journals and their influence in disseminating medical information calls for a precise scientific and executive administration in publishing standards and also in the quality of content.

    Among the 16 species of Eimeria from goats, Eimeria arloingi and Eimeria ninakohlyakimovae are regarded as the most pathogenic species in the world and cause clinical caprine coccidiosis. E. arloingi is known to be an important cause of coccidiosis in Iranian kids. Molecular analyses of two portions of nuclear ribosomal DNA (internal transcribed spacer1 (ITS1) and 18S rDNA) were used for the genetic characterization of the E. arloingi. Comparison of the sequencing data of E. arloingi obtained in the present study (ITS1: KC507793 and 18S rDNA: KC507792) with other Eimeria species in the GenBank database revealed a particularly close relationship between E. arloingi and Eimeria spp. from the cattle and sheep. The phylogram based on the ITS1 sequences shows that the E. arloingi, Eimeria bovis, and Eimeria zuernii formed a distinct group separate from the other remaining Eimeria spp. in cattle and poultry. In pairwise alignment, 18S rDNA sequence derived from E. arloingi showed 99% similarity to Eimeria ahsata with differences observed at only three nucleotides. This study showed that the ITS1 and 18S rDNA gene are useful genetic markers for the specific identification and differentiation of Eimeria spp. in ruminants.

    Theilerioses and babesioses are important diseases in Iranian sheep. The present study was undertaken to identify and classify/specify Theileria spp. and Babesia spp. in sheep and vector ticks. Investigation was carried out from 2009 to 2011 in the Khorasan Razavi Province, Iran. In total, 302 sheep originating from 60 different flocks were clinically examined and their blood collected. In addition, from the same flocks, ixodid ticks were sampled. Stained blood smears were microscopically examined for the presence of Theileria and Babesia organisms, and a semi-nested PCR was used for subsequent molecular specification. From the ticks, salivary glands and uterus were isolated and subsequently analyzed by semi-nested PCR. Piroplasm organisms were observed in 29% of the blood smears with low parasitemia, whereas 65% of the blood samples yielded positive PCR findings. The presence of Theileria ovis (55.6%), Theileria lestoquardi, and mixed infection with Theileria spp. and Babesia ovis were detected by semi-nested PCR in 0.3%, 5.6%, and 0.99%, respectively. In total, 429 ixodid ticks were collected from different areas of the province. The most prevalent ticks were Rhipicephalus turanicus (n = 376; 87.6% of the total), followed by Hyalomma marginatum turanicum (n = 30; 7.0%), Dermacentor raskemensis (n = 12; 2.8%), Hyalomma anatolicum anatolicum (n = 7; 1.6%), Dermacentor marginatus (n = 2; 0.5%), Rhipicephalus bursa (n = 1; 0.2%), and Haemaphysalis sp. (n = 1; 0.2%). Of the positive R. turanicus samples, 5 (5.7%) were infected with T. ovis and 2 (2.9%) with T. lestoquardi. Neither Babesia ovis nor Babesia motasi infection was detected in salivary glands or uterine samples of the ticks. The results also suggest that R. turanicus could be the vector responsible for transmission of the 2 Theileria species.

    Full Text Available The purpose of this research was to study genetic diversity in Indonesian sheep population using microsatellite markers. A total of 18 microsatellite loci have been used for genotyping Indonesian sheep. Total sheep blood 200 samples were extracted from garut sheep of fighting and meat types, purbalingga sheep, batur sheep and jember sheep populations by using a salting out method. Microsatellite loci data were analyzed using POPGENE 3.2 software. Based on this study obtained 180 alleles from 17 microsatellite loci, while average number of alleles was 6.10 alleles (6 to 18 alleles from five Indonesian sheep populations (garut sheep of fighting type, garut sheep of meat type, purbalingga sheep, batur sheep and jember sheep population. The average of observed heterozygosity (Ho and expected heterozygosity (He values were 0.5749 and 0.6896, respectively, while the genetic differentiation for inbreeding among population (FIS, within population (FIT and average genetic differentiation (FST were 0.1006, 0.1647 and 0.0712, respectively. Genetic distance and genetic tree showed that Indonesian sheep population was distinct from garut sheep of fighting and meat types, purbalingga sheep, batur sheep and jember sheep population. Based on this results were needed a strategy for conservation and breeding programs in each Indonesian sheep population.

    Full Text Available Abstract In order to simultaneously integrate linkage and syntenic groups to the ovine chromosomal map, a sheep bacterial artificial chromosome (BAC library was screened with previously assigned microsatellites using a sheep-hamster hybrid panel and genetic linkage. Thirty-three BACs were obtained, fluorescently labelled and hybridised on sheep-goat hybrid metaphases (2n = 57. This study allowed us, (i, to anchor all linkage groups on sheep chromosomes, (ii, to give information on the probable position of the centromere on the linkage map for the centromeric chromosomes, (iii, to contradict the previous orientation of the ovine × linkage group by the mapping of BMS1008 on OARXq38. Concerning our somatic cell hybrid panel, this study resulted in the assignment of all the previously unassigned groups to ovine chromosomes and a complete characterisation of the hybrid panel. In addition, since hybridisations were performed on a sheep-goat hybrid, new marker/anchoring points were added to the caprine cytogenetic map.

  9. The Anglo-Iranian oil dispute

    Ferrier, R.W.

    1988-01-01

    This paper traces the history of the Anglo-Iranian oil dispute. It is short-sighted to consider the Anglo-Iranian oil dispute just as a contest between Musaddiq and the AIOC: it is of wider and greater significance. The dispute illustrates a transitional phase in the difficult process of the adjustment of relations between industrialized and less developed societies for the exploitation of raw materials. Oil was already becoming a political and economic factor at the end of the Qajar period and became important during the reign of Riza Shah with his emphasis on a national program of modernization. After more attention had been focused on it during the second world war it was inevitable that it would increase in influence. The issues of the oil dispute referred back to the concessional controversies of the late nineteenth century in tobacco, mining, communications, utilities, banking even gambling, with their political and social implications; and they referred forward to the issues of the sovereignty of national resources, the transfer of technology and economic growth in relation to the standard of living. These are aspects of the North-South debate, which have yet to be satisfactorily resolved

    For those who see the trend of progress and movement of the Iranian space endeavor from the outside, it can be difficult to understand what goes on behind the scenes. However, for one who observes these events firsthand, they take on a very different meaning. In this book, the author brings new and different profiles of Iran’s space endeavor to light. Iran claims to be the ninth leading country in the world capable of manufacturing satellites and launching them, plans to land an astronaut on the Moon within a decade, and says its own president plans to be the first Iranian astronaut to travel into space. The author explains in this book that not all of these claims are quite as they seem.  In addition to technical explanations, the book also includes historical, legal, social and cultural aspects of Iran’s space program as well. It is the author’s goal to create a tangible feeling of Iran’s space endeavor for the readers.

    Full Text Available As Iran is one of the richest pistachio germplasms a few studies have been conducted on different sexes of pistachio trees, in areas where this crop emerged. To this end, 40 male and female Iranian pistachio genotypes from Feizabad region, Khorasan, Iran; were evaluated using morphological characters and randomly amplified polymorphic DNA (RAPD markers. For morphological assessments, 54 variables were considered to investigate similarities between and among the studied genotypes. Morphological data indicated relative superiority in some female genotypes (such as Sefid 1, Sefid Sabuni 2, Garmesiah, and Ghermezdorosht Z regarding characters such as halfcrackedness, the percentages of protein and fat content. 115 polymorphic bands were recorded with 92.83% average polymorphism among all primers. The total resolving power (Rp of the primers was 74.54. The range of genetic similarity varied from about 0.31 to about 0.70. Genotypes were segregated into eight groups at the similarity limit of 0.41. Results of present investigation could be helpful for strategic decisions for maintaining Iranian pistachio genotypes.

    To investigate the level and determinants of posttraumatic growth in Iranian cancer patients. This descriptive-correlational design study was conducted within a university-affiliated oncology hospital in Iran. A convenience sample of 450 patients with a definitive diagnosis of cancer of any type completed a demographic questionnaire and a posttraumatic growth inventory. Some disease-related information was obtained from patients' medical records. The mean of posttraumatic growth reported by participants was 76.1. There was a statistically significant association between experience of posttraumatic growth and age (r = - 0.21, P=0.001), education at university level (F = 8.9, P=0.001) and history of treatment by radiotherapy (t = 2.1, P=0.03). The findings of this study suggest that Iranian cancer patients experience a moderate to high level of posttraumatic growth and confirm the hypothesis that the level of posttraumatic growth in non-Western cancer patients is more than that of Western cancer patients. Although, assessing the reasons for this difference needs more investigations.

    Full Text Available Abstract Background This paper identifies the views of Iranian clinical nurses regarding the utilization of nursing research in practice. There is a need to understand what restricts Iranian clinical nurses to use research findings. The aim of this study was to identify practicing nurses' view of aspects which they perceived constrain them from research utilization that summarizes and uses research findings to address a nursing practice problem. Methods Data were collected during 6 months by means of face-to face interviews follow by one focus group. Analysis was undertaken using a qualitative content analysis. Results Findings disclosed some key themes perceived by nurses to restrict them to use research findings: level of support require to be research active, to be research minded, the extent of nurses knowledge and skills about research and research utilization, level of educational preparation relating to using research, administration and executive challenges in clinical setting, and theory-practice gap. Conclusion This study identifies constraints that require to be overcome for clinical nurses to actively get involved in research utilization. In this study nurses were generally interested to use research findings. However they felt restricted because of lack of time, lack of peer and manager support and limited knowledge and skills of the research process. This study also confirms that research utilization and the change to research nursing practice are complex issues which require both organizational and educational efforts.

    Full Text Available The purpose of our research was to determine which groups and species of internal parasites endanger the health of sheep on the islands of Rab and Pag. The research was carried out in 10 flocks on both islands taking the fresh dung out of 30% of the total number of sheep in each flock. It was ascertained that the gastrointestinal parasites and protozoa of Eimeria genus are present in most flocks on both islands. The presence of the fluke Dicrocoelium dendriticum was ascertained in considerably larger number of flocks on the island of Rab than on the island of Pag. On the other hand, the presence of parasites of Moniezia and Nematodirus genus was ascertained in larger number of flocks on the island of Pag. In two flocks on Rab parasites of Protostrongylus genus were ascertained while on the island of Pag they were not found in any flock.

    Bone blood flow in sheep tibia has been estimated via the measurement of the perfusion limited clearance of 41 Ar from the bone mineral matrix following fast neutron activation of 44 Ca. Tibia blood flows were estimated for the intact sheep, and after the installation of an intramedullary pressure tap to elevate bone marrow pressure by saline infusion. The results indicate that normal blood flow in the tibia is in the range of 1.1 to 3.7 ml/100ml-min in the intact animal and at normal marrow pressure. With an elevated intramedullary pressure of approximately 100 mmHg, the bone blood flow measured varied around 0.5 to 1.1 ml/100ml-min. 12 refs., 5 figs., 1 tab

  17. Sheep models of polycystic ovary syndrome phenotype

    Veiga-Lopez, Almudena

    2012-01-01

    Polycystic ovary syndrome (PCOS) is a fertility disorder affecting 5–7% of reproductive-aged women. Women with PCOS manifest both reproductive and metabolic defects. Several animal models have evolved, which implicate excess steroid exposure during fetal life in the development of the PCOS phenotype. This review addresses the fetal and adult reproductive and metabolic consequences of prenatal steroid excess in sheep and the translational relevance of these findings to PCOS. By comparing findings in various breeds of sheep, the review targets the role of genetic susceptibility to fetal insults. Disruptions induced by prenatal testosterone excess are evident at both the reproductive and metabolic level with each influencing the other thus creating a self-perpetuating vicious cycle. The review highlights the need for identifying a common mediator of the dysfunctions at the reproductive and metabolic levels and developing prevention and treatment interventions targeting all sites of disruption in unison for achieving optimal success.

    Restraint of a mature Moufflon sheep resulted in severe fracture and luxation of a previously osteoarthritic tibiotarsal joint. Arthrodesis was accomplished by means of internal pin fixation and an external fiberglass cast. After 3 months of hospitalization, the ram was returned to the original flock. Competition for dominance within the flock resulted in physical trauma to the ram. Seven months after surgery, the ram sustained a fractured ulna and died from exposure.

    Full Text Available With a national flock of  10.07 million sheep, Romania currently occupies the 3rd place in the EU (after the UK and Spain in terms of the sheep numbers. However, only 0.85% (85.419 heads are being reared in organic production systems. The development of sheep breeding in organic systems is very heavily influenced by the economic factors, but also by the consumer demand for organic products. An empirical study on consumer behavior towards sheep meat produced in organic system was developed in 2016. The aim of the study was to assess the possibility of developing sheep breeding sector in the organic system, in the terms of the consumer’s behavior towards  sheep meat obtained in organic system in order to develop strategies that will lead to sustainable development of the sector. The finding shown that 85% of consumers consider that sheep meat produced in organic farming system is more expensive compared to that produced in the conventional systems. However, 74% of respondents believe that higher prices are justified. The availability of the respondents to pay an additional price for organic sheep product is high, hovering around 77%. Current research highlights the potential production and marketing of sheep from Romania in organic system, which could have a positive impact on overall farm income and on animal welfare.

    2000-10-01

    Cystic follicles are a significant cause of infertility in women, dairy cattle and sheep. Sheep were used as a model to identify factors that may elicit formation of cystic follicles. Insulin resistance and elevated LH activity were tested in overweight ewes because of associations among these factors and the formation of cystic follicles. Sheep were synchronized using a progesterone-releasing pessary and insulin resistance was induced during the synchronization period through administration of bovine somatotropin. Following removal of pessaries follicular growth was stimulated by treatment with eCG or eCG and hCG (PG-600). Follicular growth was monitored via daily transrectal ultrasonography and blood samples were collected for hormonal analyses. Six of 18 ewes had a subnormal or absent preovulatory gonadotropin surge and developed cystic follicles. Neither insulin resistance nor elevated LH activity were associated with formation of cystic follicles. Ewes that developed cystic follicles were heavier (93 +/- 4 kg) than ewes that ovulated (81 +/- 3 kg; P = 0.02). Furthermore, following pessary removal and initiation of daily ultrasonography, ewes that developed cystic follicles lost body weight (-3 +/- 1%), while ovulatory ewes continued to gain body weight (1 +/- 1%; P = 0.005). It is speculated that in heavy ewes metabolic factors associated with acute body weight loss inhibit the positive feedback of estradiol and thereby suppress the preovulatory gonadotropin surge leading to formation of cystic follicles.

    Talafha, Abdelsalam Q; Ababneh, Mohammed M

    2011-10-01

    Awassi is the local breed of sheep in Jordan and is the most important breed in the semi-arid regions of the near east countries. Awassi ram and ewe lambs reach puberty at around 8 and 9 months of age, respectively. The breeding season of Awassi ewes starts as early as April and lasts through September. After puberty, Awassi rams are sexually active throughout the year. The normal estrous cycle in Awassi ewes is 15-20 days (average 17 days). Estrus ranges from 16-59 h (average 29 h) during the breeding season. The reproductive performance of unimproved Awassi sheep has been low while improved Awassi has the highest fertility and milk production and are the heaviest among all Awassi populations. The gestation length varies from 149 to 155 days (average 152 days). Hormones that are commonly used for induction and synchronization of estrus in Awassi ewes include progestins, gonadotropins and PGF2α. An Awassi ewe produces 40-60 and 70-80 kg of milk per 150-day lactation period under traditional and improved production systems, respectively, in addition to the suckled milk left for lambs until weaning. The improved Awassi has the highest milk production among all Awassi populations and may reach 506 L over 214-day lactation period. The objective of this review is to summarize the reproductive pattern and milk production of Awassi sheep in the Middle East region.

  6. Live monitoring of cattle, reindeer and sheep

    After the Chernobyl accident the fallout differed considerably from area to area in Norway and specially were found from soil samples that the mountain pasture in Middle and South of Norway were heavily contaminated. These natural ecosystem is important in several nutrition pathways; notably sheep, goat, reindeer and cattle. In June 1986 the Health Directorate imposed action levels for the nuclides Cs-134 and Cs-137. The action levels were 370 Bq/kg for milk and baby food and 600 Bq/kg for all other types of food. In November 1986, the action level for reindeer meat were increased to 6000 Bq/kg, and in June 1987 the level was also increased to 6000 Bq/kg for wild freshwater fish. The most effected meat production were reindeer, sheep and cattle. Almost 20 to 35% of the sheep had activity levels above the action limits. This fact initiated a broad program to establish effective measure to increase the activity levels and to sort out the animals which could be slaughtered. Three main approaches have been utilized in Norway in order to achieve this and to limit the potential health risk: action aimed at reducing uptake from soil to vegetation (plowing, use of fertilizing etc.); action aimed at reducing uptake from fodder to animals (use of cesium binder, change of slaughter time), or reducing unacceptable activity levels in animals (downfeeding); action aimed at reducing intake to human (interdiction, dietary advice). Live monitoring were in several of these actions necessary for a successful result

    Full Text Available Healing of skin wound is a multi-factorial and complex process. Proper treatment of diabetic wounds is still a major clinical challenge. Although diabetes mellitus can occur in ruminants, healing of wounds in diabetic ruminants has not yet been investigated. The aim of this study was to evaluate healing of ovine excisional diabetic wound model. Eight 4-month-old Iranian Makoui wethers were equally divided to diabetic and nondiabetic groups. Alloxan monohydrate (60 mg kg-1, IV was used for diabetes induction. In each wether, an excisional wound was created on the dorsum of the animal. Photographs were taken in distinct times for planimetric evaluation. Wound samples were taken on day 21 post-wounding for histopathologic evaluations of epidermal thickness, number of fibroblasts and number of new blood vessels. The planimetric study showed slightly delay in wound closure of diabetic animals, however, it was not significantly different from nondiabetic wounds (p ≥ 0.05. Furthermore, epidermal thickness, number of fibroblasts and number of blood vessels were significantly lower in diabetic group (p < 0.05. We concluded that healing of excisional diabetic wounds in sheep may be compromised, as seen in other species. However, contraction rate of these wounds may not be delayed due to metabolic features of ruminants and these animals might go under surgeries without any serious concern. However, healing quality of these wounds may be lower than normal wounds.

  14. Epidemic pasteurellosis in a bighorn sheep population coinciding with the appearance of a domestic sheep.

    A pneumonia epidemic reduced bighorn sheep (Ovis canadensis) survival and recruitment during 1997-2000 in a population comprised of three interconnected wintering herds (Kenosha Mountains, Sugarloaf Mountain, Twin Eagles) that inhabited the Kenosha and Tarryall Mountain ranges in central Colorado, USA. The onset of this epidemic coincided temporally and spatially with the appearance of a single domestic sheep (Ovis aires) on the Sugarloaf Mountain herd's winter range in December 1997. Although only bighorns in the Sugarloaf Mountain herd were affected in 1997-98, cases also occurred during 1998-99 in the other two wintering herds, likely after the epidemic spread via established seasonal movements of male bighorns. In all, we located 86 bighorn carcasses during 1997-2000. Three species of Pasteurella were isolated in various combinations from affected lung tissues from 20 bighorn carcasses where tissues were available and suitable for diagnostic evaluation; with one exception, beta-hemolytic mannheimia (Pasteurella) haemolytica (primarily reported as biogroup 1(G) or 1(alphaG)) was isolated from lung tissues of cases evaluated during winter 1997-98. The epidemic dramatically lowered adult bighorn monthly survival in all three herds; a model that included an acute epidemic effect, differing between sexes and with vaccination status, that diminished linearly over the next 12 mo best represented field data. In addition to the direct mortality associated with epidemics in these three herds, lamb recruitment in years following the pneumonia epidemic also was depressed as compared to years prior to the epidemic. Based on observations presented here, pasteurellosis epidemics in free-ranging bighorn sheep can arise through incursion of domestic sheep onto native ranges, and thus minimizing contact between domestic and bighorn sheep appears to be a logical principle for bighorn sheep conservation.

    Studying the history of science could help develop an understanding of the contributions made by ancient nations towards scientific advances. Although Iranians had an important impact on the improvement of science, the history of Iranian medicine seems not to have been given enough attention by historians. The present study focused on the history of anesthesia and pain management in Iranian medical history. In this regard, related books such as Avesta and Shahnameh were studied in order to obtain the history of anesthesiology in Iranian pre Islamic era. This subject was also studied in the famous books of Rhazes, Haly Abbas, Avicenna, Jorjani, MomenTunekaboni and Aghili from different times of the Islamic era. Scientific data bases such as PubMed, Scopus and Google Scholar were searched using key words "Iranian", "Persian", "pain management" and "anesthesia". It was discovered that pain management and anesthesiology were well known to the Iranians. Rhazes and Avicenna had innovations in this regard. Fourteen Mokhader (anesthetic) herbs, which were included in the collection of the previous knowledge of the 18th century entitled Makhzan al-Advieyh and used as the Persian Materia Medica, were identified and listed. This study introduces the history of anesthesiology and pain management at different periods in the history of Iran.

    Full Text Available The major aim of this study was to determine the antimicrobial activity of the extracts of eight plant species which are endemic in Iran. The antimicrobial activities of the extracts of eight Iranian traditional plants, including Hypericum scabrum, Myrtus communis, Pistachia atlantica, Arnebia euchroma, Salvia hydrangea, Satureja bachtiarica, Thymus daenensis and Kelussia odoratissima, were investigated against Escherichia coli O157:H7, Bacillus cereus, Listeria monocytogenes and Candida albicans by agar disc diffusion and serial dilution assays. Most of the extracts showed a relatively high antimicrobial activity against all the tested bacteria and fungi. Of the plants studied, the most active extracts were those obtained from the essential oils of M. communis and T. daenensis. The MIC values for active extract and essential oil ranged between 0.039 and 10 mg/ml. It can be said that the extract and essential oil of some medicinal plants could be used as natural antimicrobial agents in food preservation. .

    Upgrading heavy crude oil to light crude oil is one of the most important refining processes. Familiarity with the kinetics and related kinetic models is one of the important aspects of developing expertise in this field. This joint study between the NIOC Institute of Research of the Petroleum Industry and Sharif University was undertaken to determine the most appropriate upgrading process for Iranian heavy feed stock and to predict the conversion and product distribution in commercial hydrocracking units. The study involved the evaluation of stoichiometry of the hydrocracking process, focusing on the catalytic hydrocracking of furfural extract (a by-product of the lubricating oil plant) of the Tehran refinery. A pilot plant reactor was used. Good correspondence between model predictions and theoretical values was obtained.

    Little is known of the parasitic fauna of terrestrial snakes in Iran. This study aimed to evaluate the parasitic infection rates of snakes in Iran. A total of 87 snakes belonging to eight different species, that were collected between May 2012 and September 2012 and died after the hold in captivity, under which they were kept for taking poisons, were examined for the presence of gastrointestinal and blood parasites. According to our study 12 different genera of endoparasites in 64 (73.56%) of 87 examined snakes were determined. Forty one snakes (47.12%) had gastrointestinal parasites. In prepared blood smears, it was found that in 23 (26.43%) of 87 examined snakes there are at least one hemoparasite. To our knowledge, these are the first data on the internal parasitic fauna of Iranian terrestrial snakes and our findings show a higher prevalence of these organisms among them.

    It seems that there is a relationship between consanguinity and profound hearing loss but there is little data about the association of consanguinity and hearing loss in Iran. The aim of this study is to demonstrate the causes of profound bilateral sensorineural hearing loss among Iranian samples who are candidates for cochlear implantation. This study was retrospective, analytical, and designed to collect information about profound hearing impaired cases referred to the Baqiyatallah Cochlear implantation center using enumeration. A total of 310 children with profound hearing impairments participated in this study. They were aged from 6 months to 4 years old. The study was done between January 2007 and April 2009. Chi-square tests were used to show whether there was any statistical difference between the incidence of marital consanguinity of their parents and the normal population. Sixty-five percent of those 310 children had parents who had married with their relatives. Of the 203 (65%) parents that had consanguineous marriages, 132 were first cousins, which includes the children of two brothers (37 [11.8%] patrilateral parallel cousins), the children of two sisters (38 [12.2%] multi-lateral parallel cousins), or the children of a brother and a sister (57 [18.3%] cross cousins). Fifty-four (17.4%) of the parents were second cousins and 17 (5.2%) were beyond second cousins. Also, hearing loss etiology was obvious in 237 (76.3%) of the patients with profound hearing loss but was unknown in 73 (23.7%). Hereditary was identified as the most common cause in 33% of the cases. Our data demonstrated a 65% occurrence of consanguineous marriage among the parents of deaf children, which is statistically different from the percentage of consanguineous marriage among Iranian population (38%). This indicates an obvious relationship between severe hearing loss and consanguineous marriage.

  8. Central Asia in the Iranian geopolitical imagination

    2017-02-01

    Full Text Available This article charts Iran’s relations with Central Asia following the break-up of the Soviet Union in 1991. This event gave Iran a new set of neighbours to the north, and this came at a time when Iran was undergoing changes in the direction of its foreign policy from radical idealistic goals, such as the export of the Islamic Revolution, to more pragmatic aims, including giving priority to its own national interests and pursuing good neighbourly relations. Since 1991, Iran has attempted to develop relations towards the Central Asian states, both bilaterally and through various regional fora. Iran’s actions have been based, in part, on a greater commitment to regionalism that has been evident in Iranian foreign policy since the early 1990s. This has focused on cultivating economic, infrastructural and cultural links with the region, rather than any form of ideological crusade, and has helped reduce Iran’s international isolation. Following a historical contextualisation and explanation of the place that the lands of Central Asia hold in the Iranian geopolitical imagination, the article explores the key concerns of Iran in the region. It will examine Iran’s position on what it perceives as being the key issues shaping its Central Asian diplomacy, namely regional economic cooperation, pipeline politics, the status of the Caspian Sea, security cooperation and cultural diplomacy. This provides a revealing case study of how Iran perceives itself as a vital player in the region, seeking to emphasise the benefits of its geostrategic location, relative stability, and increasing international role following the nuclear deal.

    Full Text Available Sumatera thin tail (STT sheep are highly adapted to the local environment, no seasonal reproductive activity, and highresistance to internal parasite, but they have small body size and low mature body weight. "On Fann research" to identify morphological characteristics of intoduced breed and STT sheep, as well as an altemative conservation pattem were conducted in two location, i.e. Pulahan village, Air Batu District, Asahan Regency as the potensial area for STT sheep and Pulo Gambar village, Galang District, Deli Serdang Regency as the development area of introduced breed of sheep. The approach of Agroecosystem analysis, quantitative and qualitative characteristics of STT and introduced breed of sheep as well as interview to the farmer that raised STT in order to get recommendation of conservation pattern were aplied. The study show that STT sheep were isolated from the other area, and the populations tend to decrease from year to year. Qualitative characteristics of STT indicated smaller linear body measurements than those of introducted breed of sheep at the same age. Qualitative characteristics indicated that STT possess dominance body color of light brown and white (50.93% vs 41.28%. The STT mostly have one body color pattern (61.75%. The dominance spotted pattem were 1-10% of the body (60.29%, while the dominance of the head color was light brown (48.40%. Conservation pattern of STT are through natural process, in which the farmers are directly conserved, therefore the farmers do not have opportunity to develop their sheep farming. Therefore the conservation pattern recomnendation for STT sheep are by defending the location as "in situ conservation" or "on farm conservation" and giving "compensation program" to fanner because STT sheep farming less benefit than those of introduced breed of sheep.

    Full Text Available Abstract Partly due to climate change, and partly due to changes of human habitat occupation, the impact of tick-borne viruses is increasing. Nairobi sheep disease virus (NSDV and Ganjam virus (GV are two names for the same virus, which causes disease in sheep and goats and is currently known to be circulating in India and East Africa. The virus is transmitted by ixodid ticks and causes a severe hemorrhagic disease. We have developed a real-time PCR assay for the virus genome and validated it in a pilot study of the pathogenicity induced by two different isolates of NSDV/GV. One isolate was highly adapted to tissue culture, grew in most cell lines tested, and was essentially apathogenic in sheep. The second isolate appeared to be poorly adapted to cell culture and retained pathogenicity in sheep. The real-time PCR assay for virus easily detected 4 copies or less of the viral genome, and allowed a quantitative measure of the virus in whole blood. Measurement of the changes in cytokine mRNAs showed similar changes to those observed in humans infected by the closely related virus Crimean Congo hemorrhagic fever virus.

    Full Text Available A total of 75 sheep and goats from apparently healthy and from clinically affected flocks were examined for Coenurus cerebralis cysts from different localities in Egypt. Of 25 animals examined from clinically diseased sheep and goats, 25 (100% revealed the presence of infestation with one to four coenuri in the brain. The sites of predilection were the left hemisphere (48%, followed by the right hemisphere (40% and the cerebellum (12%. There was no apparent effect of the age of sheep and goats on susceptibility to infestation with C. cerebralis. Another 50 animals from apparently healthy sheep and goat herds presented no C. cerebralis cysts. The cysts from infested sheep could infest newborn puppies experimentally, with a prepatent period of 60 days post infestation. A total of 15 immature worms that were recovered from one puppy did not reach patency until 105 days post infestation with C. cerebralis cyst scolices. Pathological changes in C. cerebralis-infested sheep brain revealed parasitic elements, demyelinated nerve tracts, hyperaemic blood vessels with round cell infiltration, encephalomalacia with round cell infiltration and palisading macrophages and giant cells, as well as focal replacement of the brain parenchyma with caseated and calcified materials. The morphological characteristics of both the larval stage from sheep and goats and adult worms of Taenia multiceps from experimentally infested dogs are described. The results conclude that C. cerebralis is one of the principal causes of nervous manifestations of coenurosis in clinically diseased sheep and goats in Egypt.

    The domestication of livestock represented a crucial step in human history. By using endogenous retroviruses as genetic markers, we found that sheep differentiated on the basis of their “retrotype” and morphological traits, dispersed across Eurasia and Africa via separate migratory episodes. Relicts of the first migrations include the Mouflon, as well as breeds previously recognized as “primitive” on the basis of their morphology, such as the Orkney, Soay and the Nordic short-tailed sheep now confined to the periphery of NW Europe. A later migratory episode, involving sheep with improved production traits, shaped the vast majority of present-day breeds. The ability to differentiate genetically primitive sheep from more modern breeds provides valuable insights into the history of sheep domestication. PMID:19390051

    The origins of domesticated sheep (Ovis sp.) in China remain unknown. Previous workers have speculated that sheep may have been present in China up to 7000 years ago, however many claims are based on associations with archaeological material rather than independent dates on sheep material. Here we present 7 radiocarbon dates on sheep bone from Inner Mongolia, Ningxia and Shaanxi provinces. DNA analysis on one of the bones confirms it is Ovis sp. The oldest ages are about 4700 to 4400 BCE and are thus the oldest objectively dated Ovis material in eastern Asia. The graphitisised bone collagen had δ13C values indicating some millet was represented in the diet. This probably indicates sheep were in a domestic setting where millet was grown. The younger samples had δ13C values indicating that even more millet was in the diet, and this was likely related to changes in foddering practices

    Qualitative and quantitative histological changes in the sexual apparatus of slovak merino ewes were studies in the anoestrous period after irradiation (2.5 Gy) and hormonal stimulation. Estrus synchronization of the sheep has been carried out by application of 20 mg chlorosuperlutine in impregnated vaginal Ageline sponges. The sheep were hormone stimulated by application of 1500 IU of Serum gonadotrophin. The animals were killed approximately 120 h after the application of the hormone. Samples from the sexual apparatus were processed by the common histological methods for examination under a light microscope and for examination under a scanning electron microscope (SEM). Despite higher number of ovulations in irradiated and hormonally stimulated sheep, the examination of viability of irradiated oocytes showed absence of pregnancy in all 20 sheep after mating. This indicated that the dose of 2.5 Gy was not harmless to the reproductive system of sheep. (authors)

    1987-01-01

    The control of phosphorus excretion in sheep has been examined by constructing a kinetic model that contains a mechanistic set of connections between blood and gastrointestinal tract. The model was developed using experimental data from chaff-fed sheep and gives an accurate description of the absorption and excretion of 32 P phosphorus in feces and urine of the ruminating sheep. These results indicated the main control site for phosphorus excretion in the ruminating sheep was the gastrointestinal tract, whereas for the non-ruminating sheep fed the liquid diet, control was exerted by the kidney. A critical factor in the induction of adaptation of phosphorus reabsorption by the kidney was the reduction in salivation, and since this response occurred independently of marked changes in the delivery of phosphorus to the kidney, a humoral factor may be involved in this communication between salivary gland and kidney

    Low lamb recruitment is a major challenge facing managers attempting to mitigate the decline of bighorn sheep (Ovis canadensis), and investigations into the underlying mechanisms are limited because of the inability to readily capture and monitor bighorn sheep lambs. We evaluated 4 capture techniques for bighorn sheep lambs: 1) hand-capture of lambs from radiocollared adult females fitted with vaginal implant transmitters (VITs), 2) hand-capture of lambs of intensively monitored radiocollared adult females, 3) helicopter net-gunning, and 4) hand-capture of lambs from helicopters. During 2010–2012, we successfully captured 90% of lambs from females that retained VITs to ≤1 day of parturition, although we noted differences in capture rates between an area of high road density in the Black Hills (92–100%) of South Dakota, USA, and less accessible areas of New Mexico (71%), USA. Retention of VITs was 78% with pre-partum expulsion the main cause of failure. We were less likely to capture lambs from females that expelled VITs ≥1 day of parturition (range = 80–83%) or females that were collared without VITs (range = 60–78%). We used helicopter net-gunning at several sites in 1999, 2001–2002, and 2011, and it proved a useful technique; however, at one site, attempts to capture lambs led to lamb predation by golden eagles (Aquila chrysaetos). We attempted helicopter hand-captures at one site in 1999, and they also were successful in certain circumstances and avoided risk of physical trauma from net-gunning; however, application was limited. In areas of low accessibility or if personnel lack the ability to monitor females and/or VITs for extended periods, helicopter capture may provide a viable option for lamb capture.

    Full Text Available Abstract Background The progression of scrapie is known to be influenced by the amino acid polymorphisms of the host prion protein (PrP gene. There is no breeding programme for TSE resistance in sheep in Finland, but a scrapie control programme has been in place since 1995. In this study we have analysed PrP genotypes of total of 928 purebred and crossbred sheep together with the data of scrapie survey carried out in Finland during 2002–2008 in order to gain knowledge of the genotype distribution and scrapie prevalence in Finnish sheep. Results The ARQ/ARQ genotype was the most common genotype in all breeds studied. ARR allele frequency was less than 12% in purebred Finnish sheep and in most genotypes heterozygous for ARR, the second allele was ARQ. The VRQ allele was not detected in the Grey race sheep of Kainuu or in the Aland sheep, and it was present in less than 6% of the Finnish Landrace sheep. Leucine was the most prominent amino acid found in codon 141. In addition, one novel prion dimorphisms of Q220L was detected. During the scrapie survey of over 15 000 sheep in 2002–2008, no classical scrapie cases and only five atypical scrapie cases were detected. Conclusions The results indicate that the Finnish sheep populations have genetically little resistance to classical scrapie, but no classical scrapie was detected during an extensive survey in 2002–2008. However, five atypical scrapie cases emerged; thus, the disease is present in the Finnish sheep population at a low level.

    Blue sheep (Pseudois nayaur), a Central Asian ungulate with restricted geographic distribution, exhibits unclear variation in morphology and phylogeographic structure. The composition of species and subspecies in the genus Pseudois is controversial, particularly with respect to the taxonomic designation of geographically restricted populations. Here, 26 specimens including 5 dwarf blue sheep (Pseudois schaeferi), which were collected from a broad geographic region in China, were analyzed for 2 mitochondrial DNA fragments (cytochrome b and control region sequences). In a pattern consistent with geographically defined subspecies, we found three deeply divergent mitochondrial lineages restricted to different geographic regions. The currently designated two subspecies of blue sheep, Pseudois nayaur nayaur and Pseudois nayaur szechuanensis, were recognized in the phylogenetic trees. In addition, the Helan Mountain population showed distinct genetic characteristics from other geographic populations, and thus should be classified as a new subspecies. In contrast, dwarf blue sheep clustered closely with some blue sheep from Sichuan Province in the phylogenetic trees. Therefore, dwarf blue sheep appear to be a subset of Pseudois nayaur szechuanensis. After considering both population genetic information and molecular clock analysis, we obtained some relevant molecular phylogeographic information concerning the historical biogeography of blue sheep. These results also indicate that western Sichuan was a potential refugium for blue sheep during the Quaternary period.

    Full Text Available Serum samples from 600 sheep were collected from 5 different provinces randomly chosen in South Africa. Two sheep abattoirs (representing formal slaughter of sheep and 1 rural location (representing informal slaughter of sheep per province were also selected randomly. The serum samples were tested for anti-Toxoplasma gondii IgG antibodies using 2 different serological tests : an indirect fluorescent antibody (IFA test and an enzyme-linked immunosorbent assay (ELISA test available as a commercial kit. This study provides the first published data on seroprevalence of toxoplasmosis in sheep in South Africa, although positive titres have been found previously in wild felids, ferrets, chinchillas and a dog. Data on seroprevalence in sheep is considered important because consumption of mutton is universally considered to be a source of zoonotic transfer to humans. Seroprevalence in humans in South Africa was previously found to be 20% and it is postulated that this may be linked to the informal slaughter and consumption of mutton. During this study, the overall national seroprevalence per province in sheep was found to be 5.6 % (IFA and 4.3 % (ELISA, respectively. This is lower than in other countries, possibly because South Africa has an arid climate. Differences in seroprevalence in different areas studied suggested an association with the climate and a significant correlation (P > 0.05 was detected between the prevalence of T. gondii and the minimum average temperature. The seroprevalence was found to be significantly higher (P < 0.01 in sheep originating from commercial farms (7.9 % than in rural sheep in the informal sector (3.4 %. Also, sheep managed extensively had a seroprevalence of 1.8 %, which was significantly lower (P < 0.05 than the seroprevalence in sheep under semi-intensive or intensive management systems (5.3 %. An incidental finding of interest was the considerable movement of sheep to abattoirs and mutton after slaughter. The

    Full Text Available Sheep scab mites, Psoroptes ovis, collected from a Merino donor sheep, were used to infest Merino and Dorper sheep, and Angora and Boer goats. Mites were placed on the sheep on 1 or 2 occasions and on 5 occasions on the goats. All the animals were examined at regular intervals for the presence of scab lesions and living mites. Both sheep breeds developed lesions, but those on the Merino sheep were always larger than those on the Dorper sheep at the same intervals after infestation. None of the goats developed lesions or showed signs of irritation, or harboured any mites.

    The pathogenesis of bovine spongiform encephalopathy (BSE) in sheep was studied by immunohistochemical detection of scrapie-associated prion protein (PrP(Sc)) in the gastrointestinal, lymphoid and neural tissues following oral inoculation with BSE brain homogenate. First accumulation of PrP(Sc) was detected after 6 months in the tonsil and the ileal Peyer's patches. At 9 months postinfection, PrP(Sc) accumulation involved all gut-associated lymphoid tissues and lymph nodes as well as the spleen. At this time point, PrP(Sc) accumulation in the peripheral neural tissues was first seen in the enteric nervous system of the caudal jejunum and ileum and in the coeliac-mesenteric ganglion. In the central nervous system, PrP(Sc) was first detected in the dorsal motor nucleus of the nervus Vagus in the medulla oblongata and in the intermediolateral column in the spinal cord segments T7-L1. At subsequent time points, PrP(Sc) was seen to spread within the lymphoid system to also involve all non-gut-associated lymphoid tissues. In the enteric nervous system, further spread of PrP(Sc) involved the neural plexi along the entire gastrointestinal tract and in the CNS the complete neuraxis. These findings indicate a spread of the BSE agent in sheep from the enteric nervous system through parasympathetic and sympathetic nerves to the medulla oblongata and the spinal cord.

    Nairobi sheep disease virus (NSDV) is a tick-borne virus which causes a severe disease in sheep and goats, and has been responsible for several outbreaks of disease in East Africa. The virus is also found in the Indian subcontinent, where it is known as Ganjam virus. The virus only spreads through the feeding of competent infected ticks, and is therefore limited in its geographic distribution by the distribution of those ticks, Rhipicephalus appendiculata in Africa and Haemaphysalis intermedia in India. Animals bred in endemic areas do not normally develop disease, and the impact is therefore primarily on animals being moved for trade or breeding purposes. The disease caused by NSDV has similarities to several other ruminant diseases, and laboratory diagnosis is necessary for confirmation. There are published methods for diagnosis based on polymerase chain reaction, for virus growth in cell culture and for other simple diagnostic tests, though none has been commercialised. There is no established vaccine against NSDV, although cell-culture attenuated strains have been developed which show promise and could be put into field trials if it were deemed necessary. The virus is closely related to Crimean-Congo haemorrhagic fever virus, and studies on NSDV may therefore be useful in understanding this important human pathogen.

    Nursing is a stressful job that could create physical and psychological disorders. Many studies presented information on stress, effects of coping strategies, and job satisfaction of nurses within health setting. We aimed to identify and describe nursing stresses, coping strategies and job satisfaction of Iranian nurses who are working or worked in different wards. In this review, we studied peer-reviewed journal articles on the field of stress, coping strategies and job satisfaction in nursing practice, especially Iranian nurses, which were published between 2000 and 2013. In this regard, we searched databases of PubMed, Elsevier, Google, BMJ, PMC, and MEDLINE. The majority of the studies (60%) had analyzed the effect of coping strategies, experiences and perception of job-related stresses in Iranian nurses working in hospitals. In some of the reviewed studies (60%), the majority of the samples enrolled Iranian nurses. Forty percent of studies selected a maximum sample size of 565 (44%) participants in 2011. Nursing stress scale employed at 30% of the studies was the most commonly used strategy. This reviewed studies also revealed a combined measurement (60% of studies), based on categorical stress measurement, effects of coping strategies, and job satisfaction methods. Three studies explored the relationship between job stress and job satisfaction. For instance, the majority (74.4%) of nurses reported job satisfaction. Effect of coping strategies and job satisfaction on Iranian nurses is a well-accepted issue and has important positive outcomes on several areas of health discipline.

    Full Text Available Abstract Background We describe corneal endothelial cell density and morphology in normal Iranian eyes and compare endothelial cell characteristics in the Iranian population with data available in the literature for American and Indian populations. Methods Specular microscopy was performed in 525 eyes of normal Iranian people aged 20 to 85 years old. The studied parameters including mean endothelial cell density (MCD, mean cell area (MCA and coefficient of variation (CV in cell area were analyzed in all of the 525 eyes. Results MCD was 1961 ± 457 cell/mm2 and MCA was 537.0 ± 137.4 μm2. There was no statistically significant difference in MCD, MCA and CV between genders (Student t-test, P = 0.85, P = 0.97 and P = 0.15 respectively. There was a statistically significant decrease in MCD with age (P r = -0.64. The rate of cell loss was 0.6% per year. There was also a statistically significant increase in MCA (P r = 0.56 and CV (P r = 0.30 from 20 to 85 years of age. Conclusion The first normative data for the endothelium of Iranian eyes seems to confirm that there are no differences in MCD, MCA and CV between genders. Nevertheless, the values obtained in Iranian eyes seem to be different to those reported by the literature in Indian and American populations.

    Full Text Available A wide range of population, 4% to 30%, suffers from tinnitus that is defined as perception of sound without apparent acoustic stimulus. We conducted the present study to determine the prevalence of tinnitus in Iranian population; Tehran province. This cross-sectional study was conducted from January 2009 to December 2009, recruiting 3207 individuals (age range, 7-98 who were residing in Tehran province, Iran. Participants were asked to fill two questionnaires; the validated Persian version of Tinnitus Questionnaire (TQ and another one that was specifically designed for this study. Prevalence of tinnitus and its association factors were evaluated. 3207 participants enrolled into our study comprising 1429 (44.7% male and 1765 (55.3% female with mean age of 55.01±17.85. Of total of 3207 participants, 146 (4.6% had tinnitus consisting of 80 male (54.8% and 66 (45.2% female participants. It showed a rising trend with increasing age that was especially significant after the sixth decade of life (P=0.001. The analysis showed mean TQ global score of 35.96±25.52 that was significantly different between male and female participants (P=0.051 and had no significant correlation with increasing age (Spearman's r=0.1, P=0.10.

    The present study was aimed to evaluate E. granulosus genotypes isolated from goats using HRM analysis in Isfahan province. Cystic echincoccosis, so-called hydatidosis, is widespread infection caused by the larval stage of Echinococcus granulosus . This is an important zoonotic disease worldwide, especially in the developing countries such as Iran. To date, molecular studies mainly based on the mitochondrial DNA sequences have identified distinct genotypes termed G1-G10 which can differ in some characteristics such as the growth and infectivity to different intermediate hosts or the survival rate in the definitive hosts that are important for the development of control strategies. From August to December 2014, 1341 goats were investigated and hydatid cysts were collected from the liver and lungs of 43 infected goats in Isfahan province abattoirs, Isfahan, Iran. Total genomic DNA was extracted from each sample, amplified for the presence of polymorphism of mitochondrial gene coding for cytochrome c oxidase subunit 1 (CO1), using high resolution melting curve (HRM) method. the results of HRM analysis using the sequence of CO1 gene for 43 Echinococcus granulosus isolates from goats showed 31, 2 and 10 isolates were identified as G1, G2, and G3 genotypes, respectively. G1 is the predominant genotype in the isolated goat samples in Isfahan province, and the presence of G2 strain was reported for the first time in goat in Iran.

  15. ORIGIN, HISTORY AND CURRENT SITUATION OF PELIBUEY SHEEP IN MEXICO

    2017-12-01

    Full Text Available Domestic sheep (Ovis aries is descendant from Asian mouflon and was domesticated in the Near East. Later, sheep began its dissemination to West Africa, where it is believed that the ancestry of Pelibuey sheep came from. Pelibuey sheep were brought to America by the Spaniards to feed the crew of the boats. It is unclear whether these animals came directly from West Africa or from the Canary Islands. It is considered that Pelibuey sheep entered to Mexico between 1930 and 1940, although some authors think that this breed already existed in the country in the late nineteenth century. Since 1963, Pelibuey sheep has been the most studied breed in Mexico, due to its ability to produce in tropics, as well as its high adaptability to most agro-ecological zones of the country. A brief review about productive and reproductive traits in current Pelibuey herds, allowed to conclude that they are very similar to those of the first sheep studied almost 50 years ago. Currently, the breed has been subjected to  non-planned crosses with other breeds to increase productivity, which puts in risk this important genetic resource. Therefore, there is a need to realize the conservation of the breed.

    Bighornsheep ( Ovis canadensis ) are more susceptible to pneumonia caused by Mannheimia haemolytica than are domestic sheep ( Ovis aries ). Leukotoxin produced by M. haemolytica is the principal virulence factor involved in pneumonia pathogenesis. Although leukotoxin is cytolytic to all subsets of ruminant leukocytes, neutrophils are the most susceptible subset. Bighorn sheep neutrophils are four- to eightfold more susceptible to leukotoxin-induced cytolysis than are domestic sheep neutrophils. We hypothesized that the higher susceptibility of bighorn sheep neutrophils, in comparison to domestic sheep neutrophils, is due to higher expression of CD18, the receptor for leukotoxin on leukocytes. Our objective was to quantify CD18 expression on neutrophils of bighorn sheep and domestic sheep. Cell-surface CD18 expression on bighorn sheep and domestic sheep neutrophils was measured as antibody binding capacity of cells by flow cytometric analysis with two fluorochrome-conjugated anti-CD18 monoclonal antibodies (BAQ30A and HUH82A) and microspheres. Contrary to our expectations, CD18 expression was higher (Psheep neutrophils in comparison to bighorn sheep neutrophils. These findings suggest that the higher in vitro susceptibility to leukotoxin of bighorn sheep neutrophils compared to domestic sheep neutrophils is not due to higher expression of the leukotoxin receptor CD18 on bighorn sheep neutrophils.

    Trypanosoma (Megatrypanum) melophagium is a parasite of sheep transmitted by sheep keds, the sheep-restricted ectoparasite Melophagus ovinus (Diptera: Hippoboscidae). Sheep keds were 100% prevalent in sheep from five organic farms in Croatia, Southeastern Europe, whereas trypanosomes morphologically compatible with T. melophagium were 86% prevalent in the guts of the sheep keds. Multilocus phylogenetic analyses using sequences of small subunit rRNA, glycosomal glyceraldehyde-3-phosphate dehydrogenase, spliced leader, and internal transcribed spacer 1 of the rDNA distinguished T. melophagium from all allied trypanosomes from other ruminant species and placed the trypanosome in the subgenus Megatrypanum. Trypanosomes from sheep keds from Croatia and Scotland, the only available isolates for comparison, shared identical sequences. All biologic and phylogenetic inferences support the restriction of T. melophagium to sheep and, especially, to the sheep keds. The comparison of trypanosomes from sheep, cattle, and deer from the same country, which was never achieved before this work, strongly supported the host-restricted specificity of trypanosomes of the subgenus Megatrypanum. Our findings indicate that with the expansion of organic farms, both sheep keds and T. melophagium may re-emerge as parasitic infections of sheep. © 2011 The Author(s) Journal of Eukaryotic Microbiology © 2011 International Society of Protistologists.

    2012-12-01

    Full Text Available Afghanistan is still not a stable state with strong central government controlling the whole state territory even after eleven years since American intervention and following the pursuit of reconstruction by allied forces. One of the main causes of this situation consists in interferences of foreign powers, which have their own particular and often mutually incompatible interests in Afghanistan. One of the most important external powers in the country is Iran. Therefore, Iranian involvement in Afghanistan is the main topic of this text. The main goal of this article is to identify and interpret major methods of Iranian enforcement of its plans in Afghanistan and also the characterization of those plans. The important issue of this text is also an understanding of effects of Iranian activities in Afghanistan and whether those actions have positive or rather negative contribution.

    Full Text Available In this work, the volatile profiles of smoked and non-smoked Iranian rice were identified, and their relative abundance was calculated and compared. Headspace solid-phase microextraction together with gas chromatography-mass spectrometry (SPME-GC-MS were used to extract and identify the volatile compounds. The main groups of volatiles in Iranian rice were aldehydes, ketones, phenol derivatives, furans, linear hydrocarbons, esters and terpenes. The chemical family aldehydes was the most abundant one in the profile of non-smoked rice, while phenol derivatives and furans predominated in smoked samples. This study is the first one reporting comparative data of volatile compounds between smoked and non-smoked Iranian rice.

    Iran in recent decade faced several regional and international sanctions in foreign trade, financial and banking services. Iran national pharmaceutical industry has always played a major role in providing medicines to the Iranian patients. However, following the sanctions it has faced profound difficulties for importing of both finished products and pharmaceutical raw materials. Although medicines are exempted from sanctions, due to restriction on money transaction and proper insurance Iranian pharmaceutical companies have to pay cash in advance for imports of medicines and raw materials or to secure offshore funds at very high risks. Current situation in Iran pharmaceutical market confirms that the sanctions against Iran are affecting ordinary citizens and national health sector which resulted to reduction of availability of lifesaving medicines in the local market and has caused increasing pain and suffering for Iranian patients.

    The energy crisis and climate change give new importance to sustainable architecture which reduces the negative impacts that buildings can have on the environment. In ancient times, architects did not have access to modern equipment and had to use natural energies to provide pleasant indoor conditions. Iran has various climatic zones and Iranian traditional architecture relied on a variety of solutions to provide for human comfort. The aim of this study is to present those solutions used in traditional Iranian architecture. This paper presents the use of the energy of the earth depth and other methods such as Syzan, a cellar, Shvadan, pool house, Zmhryr in addition to the sunken garden, which taps geothermal energy by constructing a courtyard lower than street level. This document showed that traditional Iranian architectural strategies are efficient in providing sustainable buildings and could be applied in the design of new construction.

    The major difference between Iranian traditional medicine and allopathic medicine is in the application  of  evidence  and  documents.  In  this  study,  criteria  for  evidence-based  practice  in  Iranian traditional medicine and its rules of practice were studied. The experts' views were investigated through in- depth, semi-structured interviews and the results were categorized into four main categories including Designing clinical questions/clinical question-based search, critical appraisal, resource search criteria and clinical prescription appraisal. Although the application of evidence in Iranian traditional medicine follows Evidence Based Medicine (EBM) principles but it benefits from its own rules, regulations, and criteria that are compatible with EBM.

    2007-04-01

    Full Text Available The objective of this study was to investigate the antimicrobial activity of ethanol extract of Iranian propolis on some microorganisms using disc diffusion method. The chemical composition of the propolis was also investigated using thin layer chromatography and spectrophotometric methods. Ethanol extract of propolis showed activity only against Gram-positives and fungi, whereas no activity was observed against Gram-negatives. Thin layer chromatography screening revealed the presence of pinocembrine, caffeic acid, kaempferol, phenethyl caffeate, chrysin, and galangin in Iranian propolis. The total flavonoid and phenolic contents were 7.3% and 36%, respectively, which suggests that the strong antimicrobial activity of Iranian propolis may be due to high levels of phenolic and flavonoid compounds.

An 11-item questionnaire (α= .758 was used to measure autonomy perceptions of the participants. The results revealed that Turkish teachers’ autonomy perceptions were greater than that of Iranian teachers in the three teacher autonomy dimensions. Moreover, it was observed that male and master- holder teachers perceive less autonomy than female and bachelor-holder ones; whereas, no significant relationship were observed for the age and marital status variables with any teacher autonomy dimensions. Lastly, decision making dimension was the strongest predictor of teacher autonomy among both Iranian and Turkish teachers.

    While the role of some personality traits has been comprehensively explored, scientific study of others, such as patience has been neglected. Psychologists have paid scant attention to patience as a personality trait, character strength or virtue. The current study examined the relationship between patience and life satisfaction, mental health, and personality. A sample of 252 Iranian college students (129 females and 123 males) completed the 3-factor patience scale, satisfaction with life scale, general health questionnaire, anxiety and depression scales and mini international personality item pool-big five. The three types of patience (interpersonal, life hardship, and daily hassles) were associated with higher levels of life satisfaction and lower levels of depression, anxiety and psychological dysfunction. Patience also showed moderate relationship with the Big-Five factors of personality. After controlling the personality factors, patience managed to explain additional unique variance in life satisfaction and mental health indicators. Patience is a unique predictor of mental well-being. It is suggested that long-term patience is more important for depression and general health, whereas short-term patience is more beneficial for hedonic well-being.

    BACKGROUND: Surrogacy arrangements are multifaceted in nature, involving multiple controversial aspects and engaging ethical, moral, psychological and social issues. Successful treatment in reproductive medicine is strongly based on the mutual agreement of both partners, especially in Iran where men often make the final decision for health-related problems of this nature. AIM: The aim of the following study is to assess the attitudes of Iranian infertile couples toward surrogacy. SETTING AND DESIGN: This descriptive study was conducted at the infertility clinic of Hamadan university of medical sciences, Iran. MATERIALS AND METHODS: The study sample consisted of 150 infertile couples selected using a systematic randomized method. Data collection was based on responses to a questionnaire consisting of 22 questions. STATISTICAL ANALYSIS: P surrogacy, the overall attitudes toward surrogacy were positive (53.3% of women and 54.6% of men surveyed). CONCLUSION: Although, there was not a significant difference between the overall positive attitudes of infertile women and men toward surrogacy, the general attitude toward using this method is not strongly positive. Therefore, further efforts are required to increase the acceptability of surrogacy among infertile couples. PMID:24829531

    2004-10-01

    Full Text Available The biosurfactants are believed to be surface active components that are shed into the surrounding medium during the growth of the microorganisms. The oil degrading microorganism Acinetobacter calcoaceticus RAG-1 produces a poly-anionic biosurfactant, hetero-polysaccharide bioemulsifier termed as emulsan which forms and stabilizes oil-water emulsions with a variety of hydrophobic substrates. In the present paper results of the possibility of biosurfactant (Emulsan production by microorganisms isolated from Iranian oil reservoirs is presented. Fourthy three gram negative and gram positive, non fermentative, rod bacilli and coccobacilli shaped baceria were isolated from the oil wells of Bibi Hakimeh, Siri, Maroon, Ilam , East Paydar and West Paydar. Out of the isolated strains, 39 bacterial strains showed beta haemolytic activity, further screening revealed the emulsifying activity and surface tension. 11 out of 43 tested emulsifiers were identified as possible biosurfactant producers and two isolates produced large surface tension reduction, indicating the high probability of biosurfactant production. Further investigation revealed that, two gram negative, oxidase negative, aerobic and coccoid rods isolates were the best producers and hence designated as IL-1, PAY-4. Whole culture broth of isolates reduced surface tension from 68 mN /m to 30 and 29.1mN/m, respectively, and were stable during exposure to high salinity (10%NaCl and elevated temperatures(120C for 15 min .

    Full Text Available Comparative studies have demonstrated that the themes for corporate social responsibility (CSR initiatives are different among nations and geographic regions based on their cultural, political, legal, social, and economic contexts. In this research, which was conducted on 56 corporations from IMI100 (100 Iranian companies with highest annual sales, ranked by Industrial Management Institute or IMI, CSR themes in priority have been identified. Data collected from a semistructured questionnaire and some complementary interviews were analyzed against the results of a reference study over 100 companies from developed countries. The resulted themes, some of which may have several subthemes, were developed in three economic, environmental, and social categories. Beside these qualitative findings, two indices are constructed for indicating the “importance” of and “contribution” to each theme. The results and discussions are supposed to help business leaders, international companies inside Iran, governmental authorities, and researchers to improve CSR discussions and practices in the country where CSR undergoes a less structured platform.

    Full Text Available The Globalization accelerated the paradoxical processes of modernization by introducing the cultural homogenizations and heterogenizations: construction and deconstruction of local-communitarian identities. This is why we are facing on the one hand, the increasing of local identities and visions and on the other hand, the interference, sometimes in a conflicted way, of the latter forms with the national and global identities. In this context, the Iranian problematic is discussed by an urban anthropological theoretical approach. The main concern in this article is the everyday life styles as the most important means of the cultural identity formation and their self expressions. Social constructed space as Lefebvre put it, and Cultural Studies tradition of everyday life, have been the starting points of this paper aiming to analyze the cultural resistance phenomenon expressed in physical and bodily spaces as well as in social and intercultural relations in domains such as age, ethnics and gender. These identity schemes have been taken as minority situations when they express in a way or other, some sort of cultural or social resistance facing a dominant pattern and by this way the paper try to present some practical and applied solutions to decrease the social tensions.

    Full Text Available Patellofemoral pain syndrome (PFPS is the most common overuse syndrome in athletes. It is one of the causes of anterior knee pain in athletic population who come to the sports medicine clinic. Patellofemoral pain is more common among female athletes especially adolescents and young adults. Symptoms include: persistent pain behind the patella or peripatella. Pain increases on ascending and descending stairs and squatting and prolonged sitting. The aim of this study was to evaluate the prevalence of PFPS in Iranian female athletes. 418 female athletes aged 15-35 years were examined in five sports: Soccer (190, volleyball (103, running (42, fencing (45 and rock climbing (38. The athletes who had non- traumatic onset anterior knee pain of at least 3 months that increased in descending and ascending stairs and squatting, had no other causes of anterior knee pain such as ligament instability, bursitis, meniscal injury, tendonitis and arthritis and no history of knee surgery during the one past year were diagnosed as PFPS. 26/190 (13.68 % soccer players, 21/103(20.38 % volleyball players, 7/42 (16.66 % runners, 6/45(13.33 % fencers and 10/38 (26.31% rock climbers had patellofemoral pain. Among the 418 female athletes who were evaluated 70 had PFPS. Rock climbers were the most common athletes with PFPS followed by volleyball players and runners.

    Full Text Available Dengue fever, a mosquito-borne flavivirus infection, is endemic in Southeast Asia. Currently, incidences have been increasing among adults. There have been no published reports of dengue fever from Iran. Widespread connection between different countries may predispose them for acquisition of infection. The patient was a 58-year-old Iranian woman with acute unexplained high-grade fever for 4 days, associated with skin rash, after returning from Southeast Asia. CBC showed WBC = 1600/mm 3 and platelet count 99,000/mm 3 . The patient also had hematuria. ELISA immunoglobulin M (IgM antibodies to dengue and serum RT-PCR for dengue virus was positive. The patient managed with conservative treatment and due to good general condition and improvement specific antiviral treatment was not started. She became afebrile at the 3 rd day of hospitalization and discharged with good general condition on fourth day. She was afebrile after two weeks follow-up. Dengue fever has been increasing among adults. It should be suspected, when a patient presents with acute febrile illness and skin rashes returning from endemic region. Conservative treatment may be conducted in uncomplicated cases .

    Full Text Available Background: Surrogacy arrangements are multifaceted in nature, involving multiple controversial aspects and engaging ethical, moral, psychological and social issues. Successful treatment in reproductive medicine is strongly based on the mutual agreement of both partners, especially in Iran where men often make the final decision for health-related problems of this nature. AIM: The aim of the following study is to assess the attitudes of Iranian infertile couples toward surrogacy. Setting and Design: This descriptive study was conducted at the infertility clinic of Hamadan university of medical sciences, Iran. Materials and Methods: The study sample consisted of 150 infertile couples selected using a systematic randomized method. Data collection was based on responses to a questionnaire consisting of 22 questions. Statistical Analysis: P <0.05 were considered to be statistically significant. Results: While 33.3% of men and 43.3% of women surveyed insisted on not using surrogacy, the overall attitudes toward surrogacy were positive (53.3% of women and 54.6% of men surveyed. Conclusion: Although, there was not a significant difference between the overall positive attitudes of infertile women and men toward surrogacy, the general attitude toward using this method is not strongly positive. Therefore, further efforts are required to increase the acceptability of surrogacy among infertile couples.

    Full Text Available Since the appearance of “Audio-lingual Method”, the issue of foreign accent has been the focus of many researchers and many teachers attempted to sound as native like as possible to better teach native English accent. The present study attempted to uncover the Iranian EFL teachers’ perceptions on accent, the way they viewed their own accent, and how English accent can be improved. Totally 50 male and female teachers with different age range, qualifications, teaching and learning experiences participated in the study. The data of the study were collected using Teachers’ Perceptions of Accent Questionnaire developed by the researcher and semi-structured interviews. Based on the analysis performed on the data collected through questionnaires and interviews, it was found that teachers care about learning accent and they considered it valuable and important. They admitted that they have foreign accent to some degree and they did not seem to be happy with foreign accent and were more in favour of native like accent. Regarding the strategies to improve English accent, they mentioned techniques like listening to authentic language, understanding pronunciation rules, and comparing people’s accent with their own accent, watching English movies, noticing stress, and pronunciation patterns, imitating, speaking with native people, using books, and recording and monitoring their own speeches.

    Full Text Available The main drop - out reasons from the sport of roller skating amongst Iranian youth skaters has been examined. A questionnaire with 53 items (adopted from Enoksen, 2011 representing seven subscales namel y: training factors and facilities, executive factors and team, education and work obligations, motivational aspects, social - cultural environment, choice of other sport activities and interests and economic factors was especially developed for this researc h. Responses were measured on a Likert scale ranging from “strongly disagree” to “strongly agree” in relation to each statement. In all 11 2 skaters predominantly male (mean age 17.1, SD = 1.63 with a mean = 5.43 years of experience (SD = 2.92 that had di scontinued in the past two years completed the questionnaire. Results of one sample t - tests showed that all factors expect “social - cultural environment” are significant indicators for drop out from skating with “economical factors” scoring the highest rank ing. Correlational analysis showed that younger participants agree more strongly th at “executive factors and team” and “education and work obligations” were the best predictors of drop out. Those with fewer years of experience considered “training factors and facilities”, “motivational aspects and social and cultural environment” as more likely reasons for quitting. Implications of the findings are discussed.

    More than 18,000 patients need medical emergencies management in dental offices in Iran annually. The present study investigates medical emergencies management among Iranian dentists. From the list of the cell phone numbers of the dentists practicing in the city of Tehran, 210 dentists were selected randomly. A self-administered questionnaire was used as the data collection instrument. The questionnaire requested information on personal and professional characteristics of the dentists, as well as their knowledge and self-reported practice in the field of medical emergency management, and availability of required drugs and equipments to manage medical emergencies in their offices. Totally, 177 dentists (84%) completed the questionnaire. Less than 60% of the participants were knowledgeable about characteristics of hypoglycemic patient, chest pain with cardiac origin, and true cardiopulmonary resuscitation (CPR) practice. Regarding practice, less than one quarter of the respondents acquired acceptable scores. In regression models, higher practice scores were significantly associated with higher knowledge scores (p < 0.001). The results call for a need to further education on the subject for dentists. Continuing education and changing dental curriculum in the various forms seems to be useful in enhancement of the self-reported knowledge and practice of dentists. To successful control of medical emergencies in the dental office, dentists must be prepared to recognize and manage a variety of such conditions. In addition to dentist's knowledge and skill, availability of necessary equipments and trained staff is also of critical importance.

    This study explored Iranian patients' experiences of cancer disclosure, paying particular attention to the ways of disclosure. Twenty cancer patients were invited to participate in this qualitative inquiry by research staff in the clinical setting. In-depth, semistructured interview data were analyzed through content analysis. The rigor of the study was established by principles of credibility, transferability, dependability, and confirmability. Four themes emerged: the atmosphere of non-disclosure, eventual disclosure, distress in knowing, and the desire for information. Non-disclosure was the norm for participants, and all individuals involved made efforts to maintain an atmosphere of non-disclosure. While a select few were informed of their diagnosis by a physician or another patient, the majority eventually became aware of their diagnosis indirectly by different ways. All participants experienced distress after disclosure. The participants wanted basic information about their prognosis and treatments from their treating physicians, but did not receive this information, and encountered difficulty accessing information elsewhere. These challenges highlight the need for changes in current medical practice in Iran, as well as patient and healthcare provider education. © 2012 Blackwell Publishing Asia Pty Ltd.

    Full Text Available Abstract: Despite the importance of body satisfaction on one’s self image and well-being, little has been written about body image or how it affects people in Iran. The aim of this study is to assess body dissatisfaction and its risk factors in the general Iranian population. The sample size for this cross-sectional study included approximately 1,200 participants (both male and female and was conducted in 2011. Body dissatisfaction (based on the Figure Rating Scale, demographic characteristics, socioeconomic status, body mass index (BMI and use of the media were recorded. Nearly two thirds of the participants were included in the middle age group and roughly half of them had a university education. Approximately two thirds of the participants were satisfied with their body. The mean score of body dissatisfaction in women was greater than men (p < 0.0001. Age, gender, marital status and BMI had a significant relationship with body dissatisfaction. The finding of this study demonstrates that in Iran, body dissatisfaction and it consequences must be addressed. While the prevalence and pattern of body dissatisfaction in Iran is as high as other Asian countries, considering cultural variation within Asian countries is also important.

    Full Text Available Introduction. Dental stones are widely used in dentistry and the success or failure of many dental treatments depend on the accuracy of these gypsums. The purpose of this study was the evaluation of Iranian dental stones and comparison between Iranian and foreign ones. In this investigation, consistency and setting time were compared between Pars Dendn, Almas and Hinrizit stones. The latter is accepted by ADA (American Dental Association. Consistency and setting time are 2 of 5 properties that are necessitated by both ADA specification No. 25 and Iranian Standard Organization specification No. 2569 for evaluation of dental stones. Methods. In this study, the number and preparation of specimens and test conditions were done according to the ADA specification No. 25 and all the measurements were done with vicat apparatus. Results. The results of this study showed that the standard consistency of Almas stone was obtained by 42ml water and 100gr powder and the setting time of this stone was 11±0.03 min. Which was with in the limits of ADA specification (12±4 min. The standard consistency of Pars Dandan stone was obrianed by 31ml water and 100 gr powder, but the setting time of this stone was 5± 0.16 min which was nt within the limits of ADA specification. Discussion: Comparison of Iranian and Hinrizit stones properties showed that two probable problems of Iranian stones are:1- Unhemogrnousity of Iranian stoned powder was caused by uncontrolled temperature, pressure and humidity in the production process of stone. 2- Impurities such as sodium chloride was responsible fo shortening of Pars Dendens setting time.

    Previous studies demonstrated that bighorn sheep (Ovis canadensis) died of pneumonia when commingled with domestic sheep (Ovis aries) but did not conclusively prove that the responsible pathogens were transmitted from domestic to bighorn sheep. The objective of this study was to determine, unambiguously, whether Mannheimia haemolytica can be transmitted from domestic to bighorn sheep when they commingle. Four isolates of M. haemolytica were obtained from the pharynx of two of four domestic sheep and tagged with a plasmid carrying the genes for green fluorescent protein (GFP) and ampicillin resistance (AP(R)). Four domestic sheep, colonized with the tagged bacteria, were kept about 10 m apart from four bighorn sheep for 1 mo with no clinical signs of pneumonia observed in the bighorn sheep during that period. The domestic and bighorn sheep were then allowed to have fence-line contact for 2 mo. During that period, three bighorn sheep acquired the tagged bacteria from the domestic sheep. At the end of the 2 mo of fence-line contact, the animals were allowed to commingle. All four bighorn sheep died 2 days to 9 days following commingling. The lungs from all four bighorn sheep showed gross and histopathologic lesions characteristic of M. haemolytica pneumonia. Tagged M. haemolytica were isolated from all four bighorn sheep, as confirmed by growth in ampicillin-containing culture medium, PCR-amplification of genes encoding GFP and Ap(R), and immunofluorescent staining of GFP. These results unequivocally demonstrate transmission of M. haemolytica from domestic to bighorn sheep, resulting in pneumonia and death of bighorn sheep.

    Full Text Available The authors review the physiological role and the daily requirement of fat-soluble vitamins (A, D, E and K, vitamin C  and water in dairy sheep. Regarding the vitamins, classical clinical symptoms and/or non-specific parameters, such as  lowered production and reproduction rates are associated with their deficiencies or excesses. Until the last decade,  these compounds were considered important only for the prevention of such alterations; currently, there is more  emphasis on their function as the vitamins can play a key role in optimising animal health. In this respect, of particu-  lar interest is the action of the antioxidant vitamins (especially vitamin C, vitamin E and beta-carotene in improving  the efficiency of the immune system.

    1983-01-01

    Neurosecretion, PAS-positive mucopolysaccharides and the Nissl substance were studied in the neurons of the rostral, medial and caudal hypothalamus of continuously irradiated ewes. The study was performed on 21 ewes of the Slovak Merino breed of a live weight of 34 kg. The animals were in the period of physiological anoestrus and their age was two to three years. The first group of six ewes was the control. The second group included 15 sheep irradiated with a total dose of 6.7 Gy (700 R) for seven days. Co 60 was used as the source of irradiation. The animals of this group were killed seven days following treatment. The ewes in the third group were left for the study of mortality. The brains were perfused with 2% buffered paraformaldehyde immediately after the bleeding of the sheep; then the brains were removed from the skulls and fixed in buffered picroformol. Paraffin slices were stained with haematoxylin-eosine, aldehyde-fuchsine and alcian blue for neurosecretion, by the PAS reaction for mucopolysaccharides and with cresyl violet for the Nissl substance. It was found that irradiation of the whole body inhibited the activity of neurosecretory cells in the rostral and medial hypothalamus, thus reducing neurosecretion. These regions also showed a reduced activity of the PAS reaction used for the demonstration of mucopolysaccharides. The observed changes also included damage of the endothelium of blood vessels with the occurrence of erythrocyte extravasates and with haemorrhages. In this way, the trophism of neurosecretory cells was affected, which is ascribed to the decrease in the amount of neurosecretory material. In the caudal hypothalamus, neurosecretion and PAS-positivity were slightly stimulated by irradiation. The Nissl substance disappeared as a result of irradiation. (author)

    In this study, we investigated recent sheep pox outbreaks that occurred in Ononsky and Borzunsky regions of Zabajkalskij kray of Russia. The outbreaks involved in 2756 animals of which 112 were infected and 3 were slaughtered. Samples of injured skin of infected sheep were analysed by electron microscopy and CaPV-specific P32 gene amplification. Following sequence analysis of entire P32 gene showed that both specimens were identical to the sequence of several sheep poxvirus isolates from China and India. The close location of China to the last decade's Russian outbreaks suggest that possible future outbreaks in Russia could occur along the border regions with countries where sheep and goat pox are not controlled. © 2013 Blackwell Verlag GmbH.

  16. The efficacy of showers for control of ectoparasites of sheep.

    Science.gov (United States)

    Kirkwood, A C; Quick, M P

    1978-01-21

    Ectoparasites of sheep in Britain include the tick Ixodes ricinus, the blowfly, Lucilia sericata, the ked, Melophagus ovinus and the lice, Damalinia ovis and Linognathus ovillus. The most important ectoparasite, however, is the mite Psoroptes communis ovis which causes sheep scab. This notifiable disease was eradicated from Britain in 1952 but was reported again in 1973. The control of ectoparasites depends largely on the efficient application of insecticide to the fleece and skin. Plunge dipping in a bath is generally regarded as the most efficient method and is compulsory for the control of sheep scab but it is not always the most convenient. After the eradication of sheep scab in 1952 plunge dipping was no longer compulsory and jetting, spraying and showering techniques were then employed for the other ectoparasites.

    Until recently, selection of dairy sheep breeds was focused almost exclusively on increasing the amount of milk produced and so today they produce several times more milk than breeds selected for meat and wool. However, due to the permanent striving for increasing sheep milk production udder weight becomes too great, and suspensory system can not withstand this overweight so it ruptures more often. That significantly shortens the duration of animal’s production life and adversely affects udde...

    Purpose: With respect to the specific characteristic of rete mirabile epidurale rostrale in sheep, the aim of this study was to investigate the use of time of flight (TOF) magnetic resonance angiography (MRA) to observe vascular anatomy and to validate MCA occlusion in a new model of experimental focal cerebral ischemia by permanent middle cerebral artery (MCA) occlusion in sheep (designed to study stroke therapy using autologous stem cells from umbilical cord blood). Furthermore, we wanted to assess the extent and natural time course of ischemic focal brain injury in sheep using functional and morphological magnetic resonance imaging (MRI). Materials and Method: 13 Merino sheep were examined. In 4 of the animals all, in 5 sheep 1 or 2 MCA branches were occluded and in 1 one case touched (sham operation). 4 controls did not undergo a surgical procedure. 23 MRI sessions were performed in 10 sheep. These sessions included T1, T2, T2 * sequences, diffusion-weighted imaging (DWI) and TOF MRA before and 2 - 46 days after the onset of stroke using a 1.5T clinical MR scanner. Corrosion casts of the cerebral arteries of 3 sheep were prepared and compared to MRA. Results: The MRA visualized the vessel anatomy or occlusion distal to the rete mirabile. Anatomical variants concerning the variant origin of the MCA and inconstant arteria choroidea rostralis and communicans rostralis were revealed. Sheep with occluded left MCA showed space occupying lesions with a drop in ADC values. Depending on the number of preserved MCA branches (0; 1; 2), highly significant (p < 0.001) differences in lesion size (21 ± 5.7; 13; 1.7 ± 1.3 ml) could be found. No indication of ischemia but minimal contusion damage was observed in the sham operated animal. (orig.)

  20. Five scenarios for the Iranian crisis

    Perkovich, G.

    2006-01-01

    Since August 2005, Iran's campaign to enrich uranium and acquire other technologies and practical experience that would enable it to produce nuclear weapons has gained momentum. President Mahmoud Ahmadinejad and militant elements in Iran's ruling circle pointedly continue to defy international demands to cease uranium enrichment while the International Atomic Energy Agency's doubts about the peacefulness of Iran's past nuclear activities remain unresolved - according to the IAEA, Iran has not provided adequate cooperation to help resolve these doubts. This obstinate stance, paired with an aggressive posture toward Israel, has heightened Ahmadinejad's popularity in the wider Arab world, including among Sunnis. The popularity of Iran's defiant position has, in turn, hardened Iran's resistance to international policy objectives to constrain the nuclear program. This essay explores five broad pathways by which Iran and the international community can try to resolve the nuclear standoff. It emphasizes that the Bush Administration after years of indecision has invested seriously in a diplomatic strategy to induce Iran to forego uranium enrichment and is prepared to pursue behavior change rather than regime change in Iran. However, Iranian resistance continues to raise the prospect that the international community will favor the competing approach of capitulation, which in turn would re-raise the prospects of military attack. 1. Capitulate to Iran and Welcome Limited Uranium Enrichment; 2. Offer Sanctions and Positive Incentives To Persuade Iran Not to Produce Nuclear Fuel (for an agreed substantial period of time); 3. Attack Iran's Nuclear Facilities and/or Military Assets; 4. Foster Regime Change in Iran; 5. Try Options 1 or 2, While Strengthening Deterrence and Containment. (author)

    To assess the potential for an epizootic of pneumonia to result from either natural immigration or translocation, we compared the seroprevalence to Mycoplasma ovipneumoniae in several populations of desert bighorn sheep in Arizona. We collected blood samples and nasal or oropharyngeal swabs from 124 desert bighorn sheep (Ovis canadensis nelsoni) from 6 populations in Arizona in 2009 and 2010. M. ovipneumoniae organisms were detected by PCR in 22%, whereas antibodies to M. ovipneumoniae were detected in 47% of tested bighorn sheep. Mycoplasma antibodies were not found in 2 of 6 populations, indicating some bighorn sheep populations in Arizona are naïve to this bacterium. In contrast, others had seroprevalence rates up to 80%. We were able to compare seroprevalence rates and titers over time in 9 individuals (7 individuals included in the 124 bighorn sheep sampled in 2009 and 2010, and 2 individuals originally captured in 2006). Antibody titers persisted for 12 months in individuals from the Kofa National Wildlife Refuge (n = 7) while antibody titers appeared to decline in the Kanab Creek population (n = 2). M. ovipneumoniae is present or has been present in several, but not all, populations of bighorn sheep in Arizona. The results demonstrate the importance of routine health testing for future translocation efforts to reduce disease risk for naive populations.

  3. Effect of chronic copper poisoning on the kidneys of sheep

    The effect of copper poisoning on kidneys was studied in 16 housed sheep given a daily drench of copper sulfate at the rate of 20 mg CuSO/sub 4/5H/sub 2/O per kg body weight. Seven similar sheep were kept as controls. All sheep were bled and weighed at weekly intervals, urine was collected via a catheter from groups of sheep at varying times and animals were killed in groups throughout the experiment. Nine sheep were allowed to develop the hemolytic crisis. Prior to hemolysis copper levels in the liver and copper and iron levels in the kidneys rose significantly, eosinophilic intracytoplasmic granules became numerous in the epithelium of the proximal convoluted tubules (PCT), but significant changes were not detected by the histochemical methods used nor was kidney function impaired. In the animals that developed hemolysis there was degeneration, necrosis and loss of enzyme activity from the cells of the PCT. The tubule cells contained large amounts of hemoglobin, copper and iron and much of this material seemed to be localized in intracytoplasmic granules that were probably lysosomes. There was marked functional impairment at this time and blood urea levels began to rise. These lesions, an interstitial fibroblastic and inflammatory cell response together with changes suggestive of tubular regeneration were seen in the posthemolytic group of sheep.

    Role of diet on colorectal cancer (CRC) has been considered in terms of single foods and nutrients, but less frequently in terms of dietary patterns in Iran. The objective of this study was to determine the association between Iranian dietary patterns and CRC. This case-control study was conducted in four hospitals in Tabriz City of Iran including 414 participants aged 35-75 years:207 cases with CRC confirmed by pathology and colonoscopy findings were selected and 207 controls free of neoplastic conditions and diet-related chronic diseases (from the same hospital at the same period for the cases). Dietary data were assessed using a 123-item semi-quantitative food frequency questionnaire. Two dietary patterns were found by using of Principal Component Analysis (PCA) method;"Healthy pattern"and "Iranian pattern". Multivariate logistic regression analysis was used to estimate adjusted odds ratios (OR) for relationship between dietary patterns and colorectal cancer. After adjusting for confounding factors, the Iranian dietary pattern was significantly associated with an increased odds of colorectal cancer (OR= 1.46; 95% Confidenec Interval (CI)=1.05-2.19) while a reduced odds of colorectal cancer was observed with the Healthy dietary pattern (OR=0.18; 95% CI= 0.091-0.47). Iranian dietary pattern (IDP) seems to increase the odds of colorectal cancer and protective effect of Healthy dietary pattern.

    2015-06-01

    Full Text Available In this article, we studied student dissertations in cultural studies departments and articles of two important journals (Iranian Journal of Cultural Research and Quarterly Journal of Iranian Association for Cultural Studies & Communication. Our main questions are how the condition of reception possibility is assumed in Iranian cultural studies? How we can classify our audiences? In particular, how and who is the audience in Iran? This analysis shows that most of the Iranian cultural studies oriented to urban middle class of Tehran, instead of lower middle class or labor class. The result demonstrates that, most of scholars consider audience as an active subject that resists against text massages. Hence, they overlook the role of ideology and power in construction of subject and audience. As if, a type of optimistic cultural studies was adapted in an authoritarian political context. This approach on resistance is called resistance ideology by the authors; a situation in which we believe resistance is a sort of relieving and appeasing drug for critical cultural scholars.

    Full Text Available Assistive technologies have always opened new horizons in human's life, posed solutions to problemsand brought relief and prosperity for human beings. Iranian judicial authorities have recently recognizedthe importance of medical technologies. Accordingly, Iranian legal system has recognized surrogacy anda surrogacy contract seems unavoidable for surrogacy to be legally valid, socially acceptable andreligiously legitimate. As a legal defense of including a typical surrogacy contract in contract law, thisreview studies the four building blocks of a valid contract: the intention and consent of parties, theirlegal capacity, the subject of the contract and its legitimacy. Discussing related Iranian Acts concerningcontracts and responsibilities of parties, the authors of the present article deal with main commitmentsand responsibilities of the parties to a typical surrogacy contract: infertile couples, surrogate, fertilityclinic or medical institute, and surrogate's husband. The authors conclude that a surrogacy contract isaccepted based on article 10 of Iranian Civil Act 1928, pose some suggestions to be included in such acontract, and emphasize that a specific Act concerning surrogacy should be approved to cover rights andlegal needs of all parties to a surrogacy contract.

    Full Text Available Different genres of underground music are important issues in Iranian youth culture. The purpose of this research was to study masculinity in Iranian- Persian rap music. Therefore, Persian rap music as a part of Iranian popular culture, between 2001 and 2011 was analyzed. We used qualitative research approach. The main method used in this study, was "Constructive Grounded Theory ". So instead of using existing theories as a theoretical framework, the researcher sought to generate local theory from research field. Thus, using theoretical sampling, data compiled from various sources. The multiple data collection techniques such as interviews, observation, online observation, collecting documents and texts were used. Then all the data was coded with using open, axial and selective coding methods. Finally, 62 concepts and 16 categories derived from data and "plural form of masculinity in Iranian-Persian rap music" was defined as the core category. Then according to paradigmatic model, "Substantive Theory" emerged from the data, was presented as "story" and "visual model". Finally seven questions of Strauss and Corbin about the experience in research has been assessed to evaluating research.

    2013-08-01

    Although the experience of sex guilt has been considered among a variety of ethnic groups, the area has not yet been empirically explored among Iranian American women. The present study investigated the relationship between sexual self-schema (i.e., beliefs about the sexual aspects of oneself), acculturation, and sex guilt, and it further examined the association between sex guilt and life satisfaction in Iranian American women. A total of 65 Iranian American women, with a mean age of 31.3 years (SD = 11.7), completed five self-administered questionnaires. Findings indicated a significant inverse correlation between sexual self-schema and sex guilt. More specifically, women who endorsed negative self-views regarding their sexual self reported higher levels sex guilt. Results revealed that acculturation was unrelated to sex guilt, when the effect of being Muslim or non-Muslim was controlled. Women with high sex guilt reported significantly lower levels of life satisfaction. Moreover, analyses for mediation effects supported sex guilt as a partially mediating variable between sexual self-schema and life satisfaction. Levels of sex guilt were higher among Muslim women when compared to women of other religious affiliations. Additionally, Muslim women appeared to be significantly less acculturated to Western ideals than other religious groups. The present findings suggest that mental health professionals who provide services to Iranian American women need to consider the negative effects of sex guilt, particularly among Muslim women.

    Fisher, M W; Gregory, N G; Muir, P D

    2012-05-01

    To assess current practices on sheep and beef farms that deprive sheep of feed prior to transport to facilitate effluent management and processing at slaughter. A national telephone survey of 122 sheep and 346 sheep and beef farmers was conducted in March and April 2010. They were asked how long sheep were held off green feed prior to transport and why, what environment the sheep were held in, and if that period ever varied. Of the 468 respondents, 303 (65%) removed their sheep from green feed 3-12 h before transport for slaughter, with longer periods reported in the South than North Island. The main reasons given were to reduce the volume of effluent for transport operators (n=174), to prevent wool staining during transport (n=173), and that sheep were better suited to load and travel empty (n=171). Water was provided during feed deprivation by 313 farmers. The period of food deprivation could be altered in response to requirements of transporters and processors, the weather, and by the class of stock involved, although 115/468 (25%) farmers stated that they never changed their normal protocol. Amongst survey respondents, common practices compared favourably with recommendations to reduce effluent during transportation. Previous studies have investigated the effects of fasting lambs whilst in lairage prior to slaughter and focussed on carcass quality such as carcass weight and tenderness. Changes in liveweight and gastrointestinal tract contents suggest feed deprivation reduces the risk of defaecation and urination contributing to the accumulation of effluent during transport and of carcass contamination during processing. However, the point at which that risk is acceptable to transport and processing is unclear. Fasting results in physiological changes indicative of altered metabolism but it is not clear when those changes are indicative of adaptation to food deprivation or metabolic depletion and compromised welfare. There may be opportunities to improve the

    The study aimed to evaluate the effects of two different sheep milk-based food matrices - fermented sheep milk and ice cream - with added probiotic bacteria (Lactobacillus casei 431) on dental enamel subjected to an in vitro highly cariogenic challenge. Sixty enamel blocks were selected and randomly allocated into five treatment groups (n=12): conventional fermented sheep milk (CFSM), probiotic fermented sheep milk (PFSM), conventional sheep milk ice cream (CSMIC), probiotic sheep milk ice cream (PSMIC) and control using deionized water. The blocks were subjected to highly cariogenic pH cycling and the products were applied (5min), in a blinded way, once a day to simulate a daily use for 8 consecutive days. A microhardness test was performed before and after the treatment to estimate the percentage of microhardness surface loss (% SML). Scanning electronic microscopy (SEM) was performed to confirm the mineral loss. All groups had lost microhardness after the experiment. However, CFSM and PFSM exhibited the most positive findings when compared to the control in both ice creams. Scanning electron microscopy showed less mineral loss in CFSM and PFSM compared with CSMIC, PSMIC and control after the cariogenic challenge. Overall, fermented milk decreased mineral loss from enamel subjected to a highly cariogenic challenge, regardless of the presence of probiotics in their composition, which had a higher efficacy compared to ice cream.

    Alzheimer disease (AD) is the most common cause of dementia. In regards to the world's aging population, control and treatment of AD will be one of the major concerns of global public health in the next century. Alzheimer disease was not mentioned with the same phrase or its equivalent in traditional medical texts. The main of present paper was to investigate symptoms and causes of alzheimer disease from the view point of Iranian traditional medicine. In this qualitative study, we searched reliable sources of Iranian traditional medicine such as Canon of Medicide by Avicenna (Al-Quanon fi- tibb), Aghili cure by Aghili's (Molajat-E-aghili), Tib-E-Akbari, Exire -E-Aazam and Sharh-E-Asbab and some reliable resources of neurology were probed base on keywords to find a disease that had the most overlap in terms of symptoms with alzheimer disease. By taking from the relevant materials, the extracted texts were compared and analyzed. Findings showed that alzheimer disease has the most overlap with Nesyan (fisad-e-zekr, fisad-e-fekr and fisad-e-takhayol) symptoms in Iranian traditional medicine. Although this is not a perfect overlap and there are causes, including coldness and dryness of the brain or coldness and wetness that could also lead to alzheimer disease according to Iranian traditional medicine. According to Iranian traditional medicine, The brain dystemperement is considered the main causes of alzheimer disease. By correcting the brain dystemperement, alzheimer can be well managed. This study helps to suggest a better strategy for preventing and treating alzheimer in the future.

    The presence of hair plays an important role in people's overall physical appearance and self-perception. As a result of increased life expectancy, the desire to look youthful plays a bigger role than ever.The use of medicinal plants is as old as mankind and the market will face many new products containing natural oils and herbs in coming years. In traditional Iranian medicine, many plants and herbal formulations are reported for hair growth as well as the improvement in hair quality. The aim of this article is to introduce effective medicinal plants in traditional Iranian medicine to prevent gray hair and advocate them as the new products. The present investigation is an overview study and has been codified by library search in the main sources of traditional Iranian medicine. In traditional Iranian medicine, three types of formulations are proposed to prevent gray hair, namely (i) treatment compounds, (ii) preventive compounds, and (iii) hair dyes to color gray hairs. Our search showed that the main parts of a plant that is used in the treatment and preventive compounds are seeds and fruits. These are primarily in the form of topical oil or oral compound (electuary). The majority of plant parts used in hair dyes is from the fruit and/or leaves. Natural products are highly popular and the use of plant extracts in formulations is on the rise. This is because synthetic based product may cause health hazards with several side effects. Considering the increased popularity of herbal drugs in hair care, it is worthwhile to conduct systemic investigation on the production and efficacy of these drugs. We trust that our investigation would encourage the use of traditional Iranian medicine in future hair care products.

    We evaluated susceptibility of Dall sheep (Ovis dalli dalli) to bacterial pneumonia induced by two strains of Pasteurella haemolytica of domestic sheep origin by evaluating the sensitivity of blood neutrophils of eight Dall sheep to lysis by cytotoxins of P. haemolytica, and by intratracheal inoculation of three Dall sheep, two bighorn sheep (Ovis canadensis), and two domestic sheep with 3.7 x 10(6) or 2.5 x 10(7) colony forming units of P. haemolytica. Neutrophils from the Dall sheep were more sensitive to lysis by cytotoxins from supernatants of a P. haemolytica, biotype A, serotype 2 (A2), of domestic sheep origin, than were neutrophils from six bighorn sheep. This cytotoxic bacterium was the same isolate that was used for intratracheal inoculation of two Dall sheep and two domestic sheep. Inoculation of this cytotoxic P. haemolytica A2 resulted in fatal fibrinopurulent pleuropneumonia in the first Dall sheep within 24 hr of inoculation, and pneumonic lesions in the second Dall sheep before it was euthanized 52 hr after inoculation. This strain of P. haemolytica A2 did not cause respiratory disease when inoculated into two domestic sheep. A noncytotoxic strain of P. haemolytica; biotype T, serotype 3,4,10 of domestic sheep origin did not result in pneumonia in the third Dall sheep or two bighorn sheep. Prior to inoculation, P. haemolytica, biotype T isolates were obtained from all three Dall sheep, but none of these isolates was cytotoxic. At necropsy, cytotoxic P. haemolytica A2 was isolated from lungs and other tissues of the two pneumonic Dall sheep. Based on these results, we conclude that Dall sheep appear to be at least as sensitive as bighorn sheep to pneumonia caused by P. haemolytica A2 of domestic sheep origin. Because in vitro and in vivo results appear closely correlated in this and other studies, we believe with additional evaluation and standardization, neutrophil cytotoxicity tests may serve as a substitute for live animal challenges in future

    At the modern age, to acquire knowledge and experience, the individuals with their own specific culture have to enter contexts with cultural diversity, adapt to different cultures and have social interactions to be able to have effective inter-cultural relationships.To have such intercultural associations and satisfy individual needs in the society, cultural intelligence and social adaptability are deemed as inevitable requirements, in particular for those who enter a quite different culture. Hence, the present study tries to compare the cultural intelligence and its aspects and social adaptability in Iranian and non-Iranian dormitory students of Isfahan University of Medical Sciences in 2012. The study was of descriptiveanalytical nature. The research population consisted of Iranian and non-Iranian students resided in the dormitories of Isfahan University of Medical Sciences which are 2500, totally. For Iranian students, two-stage sampling method was adopted. At the first stage, classified sampling and at the second stage, systematic random sampling was conducted. In this way, 441 students were selected. To form non-Iranian students' sample, consensus sampling method was applied and a sample of 37 students were obtained. The research data was collected by using Earley & Ang's Cultural Intelligence Questionnaire with the Cronbach's coefficient α of 76% and California Social Adaptability Standard Questionnaire with the Cronbach's coefficient α of over 70%. Then, the data were put into SPSS software to be analyzed. Finally, the results were presented by descriptive and inferential statistics methods. The study findings revealed that there was no statistically significant difference between cultural intelligence and cognitive aspect of cultural intelligence in Iranian and non-Iranian students (P≥0/05). However, Iranian and non-Iranian students statistically differed in terms of the following aspects of cultural intelligence: meta-cognitive aspect (61.8% for

    Full Text Available "nWe determined the frequency of clinical thyroid ophthalmopathy in Iranian patients. This cross-sectional study was performed at the Endocrinology Institute of Tehran University of Medical Sciences. All patients with documented thyroid disorders from September 2003 to July 2005 were recruited. Eye examinations included evaluation of soft tissue changes, measurement of proptosis, lid width, lagophthalmos, evaluation of eye muscle function, and determination of visual acuity. The activity of ophthalmopathy was scored according to the NOSPECS scale. Among 851 visited patients, 303 cases had thyroid eye disease (TED. The nature of the ophthalmopathy breaks down as follows: 53.4% were hypothyroid (9.3% Hashimoto disease, 5.5% euthyroid and 41.1% had Graves' disease. The prevalence of TED in males was 60% which was nearly 2 times the prevalence of TED in females. There was a significant relationship between presentation of TED and active smoking of the patients (P<0.0001 while no significant relationship with passive smoking was obtained (P=0.181. The most common clinical sign of TED in descending order respectively were proptosis with 63.4%, soft tissue involvement (40.9%, extraocular muscle involvement (22.1%, corneal involvement (12.9% and optic nerve dysfunction (6.3%. Myasthenia gravis occurred in only 2 patients. In the logistic regression, occurrence of TED was influenced by cardiovascular disease (OR=5.346, Graves' disease (OR=47.507, radioiodine therapy (OR=2.590, and anti-thyroid medications (OR=0.650. Thyroid ophtalmopathy (orbitopathy is a matter of important health concern among patients with thyroid disorder. Since TED occurred with a high prevalence in all thyroid states, a close collaboration between endocrinologists and ophthalmologists along with timely referrals of patients with any eye complaint is deemed necessary. Also smoking was the most important risk factor for developing TED. Therefore, it is advisable to raise

  6. Taenia ovis: an emerging threat to the Chinese sheep industry?

    Taenia ovis is a tapeworm that is mainly transmitted between dogs and sheep. Although T. ovis infection is not a public health issue, it causes a great financial loss due to condemnation of carcasses.  The first outbreak of T. ovis infection in China occurred in 2015. Reassessment of adverse effects of T. ovis infection on Chinese sheep industry in future is necessary. The first T. ovis outbreak in China suggests that the epidemic situation across the country is underestimated. For the transmission of T. ovis, many factors, including eggs, dogs and wild canids, human behaviours and sheep trade, should be seriously considered. In blocking the transmission chain, regular treatments of the infected dogs using anthelmintics play a crucial step, but at the moment it is difficult to be fully executed in China, largely due to the behaviours, customs and faith of local farmers. Moreover, combined with no clinical symptoms in the infected adult sheep and goats, the lack of pre-mortem diagnostic tools makes it harder to practice a national wide surveillance as well as inspection and quarantine in increasingly frequent free sheep trade activities in China, leading to an inability to restrict T. ovis infection into small areas. Furthermore, the ongoing campaigns against Echinococcus granulosus may have an adverse effect on control of T. ovis infection because of no consideration of a role of dogs in the transmission of the parasite. Lack of national epidemic data, pre-mortem diagnostic reagents and vaccines severely hampers the implementation of disease control campaigns and the restriction of T. ovis infection into small areas. Consequently, sheep and goats are at an increasing risk of T. ovis exposure and the possibility of large-scale outbreaks across China in future is possible, causing great adversity towards sheep industry.

    Objectives The present study was designed to gain information about the ultrasonographic features of livers with cystic echinococcosis, as well as to evaluate the use of ultrasonography for diagnosis of such disease in sheep. Design This was a retrospective study during the period April 2011 to March 2013. Participants A total of 22 Baladi sheep (aged three to six years) were included in this study. Based on clear hepatic ultrasonographic findings, all animals were classified into two groups: those with hepatic cysts (n=9) and without liver cysts (healthy liver, n=13). Results Biochemically, serum concentrations of γ-glutamyl transferase, aspartate aminotransferase, total bilirubin and globulins were significantly increased (P<0.01), while albumin was lowered (P<0.01) in sheep with cystic livers. Ultrasonographic findings of diseased sheep livers revealed the presence of rounded, anechoic and unilocular hydatid cysts with ellipse circumference ranged from 6–10 cm. The borders of cysts were mostly well defined. The interior of cysts contained echogenic particulate materials, septations, or fine echoes. At the 10th intercostal space, the ventral margin, size, thickness and angle of livers were higher (P<0.01), while the diameter of portal vein was lower (P<0.01) in sheep with liver cysts than control ones. Furthermore, at the 9th intercostal space, the circumference of the gall bladder was decreased in sheep with hepatic cysts (P<0.01). The sensitivity, specificity, and positive and negative predictive values of ultrasonography for diagnosis of hepatic hydatid cysts were 80 per cent and 100 per cent, and 100 per cent and 83 per cent, respectively. Conclusions Cystic echinococcosis is associated with a number of anatomical alterations in the liver tissues that can be easily recognised by ultrasound. Furthermore, ultrasonography alone or in combination with analysis of biochemical parameters reflecting liver function could be helpful for diagnosis of hepatic

    Selection of bighorn sheep (Ovis canadensis) for translocation historically has been motivated by preservation of subspecific purity rather than by adaptation of source stocks to similar environments. Our objective was to estimate cause‐specific, annual, and age‐specific mortality of introduced bighorn sheep that originated at low elevations in southern British Columbia, Canada (BC ecotype), or in the Missouri River Breaks region of central Montana, USA (MT ecotype). In North Dakota, USA, mortality was similar and typically low for adult female bighorn sheep from Montana (0.09 ± 0.029 [SE]) and British Columbia (0.08 ± 0.017) during 2000–2016. Median life expectancy was 11 years for females that reached adulthood (2 yrs old); however, mortality accelerated with age and reached 86% by age 16. Mortalities resulted primarily from low rates of predation, disease, accidents, and unknown natural causes (<0.04 [upper 90% CI]). Similar survival rates of female bighorn sheep from female bighorn sheep from British Columbia and Montana, coupled with greater recruitment of bighorn sheep from Montana, resulted in a greater projected rate of increase for the MT ecotype (λ = 1.21) than for the BC ecotype (1.02), and a more youthful age structure. These results support translocation of bighorn sheep from areas that are environmentally similar to areas that will be stocked. Potential benefits include more rapid population growth, greater resilience to and more rapid recovery from density‐independent losses, an increased possibility that rapidly growing populations will expand into adjacent habitat, increased hunter opportunity, increased connectivity among herds, and a more complete restoration of ecosystem processes.

  9. Executive decision-making in the domestic sheep.

    Full Text Available Two new large animal models of Huntington's disease (HD have been developed recently, an old world monkey (macaque and a sheep. Macaques, with their large brains and complex repertoire of behaviors are the 'gold-standard' laboratory animals for testing cognitive function, but there are many practical and ethical issues that must be resolved before HD macaques can be used for pre-clinical research. By contrast, despite their comparable brain size, sheep do not enjoy a reputation for intelligence, and are not used for pre-clinical cognitive testing. Given that cognitive decline is a major therapeutic target in HD, the feasibility of testing cognitive function in sheep must be explored if they are to be considered seriously as models of HD. Here we tested the ability of sheep to perform tests of executive function (discrimination learning, reversal learning and attentional set-shifting. Significantly, we found that not only could sheep perform discrimination learning and reversals, but they could also perform the intradimensional (ID and extradimensional (ED set-shifting tasks that are sensitive tests of cognitive dysfunction in humans. Their performance on the ID/ED shifts mirrored that seen in humans and macaques, with significantly more errors to reach criterion in the ED than the ID shift. Thus, sheep can perform 'executive' cognitive tasks that are an important part of the primate behavioral repertoire, but which have never been shown previously to exist in any other large animal. Sheep have great potential, not only for use as a large animal model of HD, but also for studying cognitive function and the evolution of complex behaviours in normal animals.

    Full Text Available Objectives: The present study aims to investigate the international status and visibility of Iranian journals which have been indexed in Journal Citation Reports (JCR. Accordingly, the number of international papers, citations and editorial board members of each journal was studied. Moreover, various measures were utilized to compare the quality of Iranian journals with their international counterparts. Method: Current paper applied scientometric research method. A total of 16471 papers which published in 38 Iranian journals and indexed by the JCR 2013 were selected as the population of the study. Web of Science (WoS, JCR and journals’ website were used for data gathering. Results: Results of the study revealed that foreign researchers have published 34.8% of papers published in Iranian ISI journals. Moreover, only 30.6% of citations to Iranian ISI journals have been received from foreign papers or Iranian internationally collaborative papers. The results showed that Iranian researchers accounted for 66.4% of editorial board member of all studied journals, while foreign researchers only occupied 33.6% of the editorial board positions. Based on the findings, only two Iranian journals have impact factors above the median of the journals in the disciplinary category areas in which they are classified in JCR. Furthermore, only 8 Iranian journals have ever been placed in the 1st and 2nd quartile of journals of the same field in the JCR. Findings also showed that 36 out of the 38 Iranian journals have mostly cited by journals with higher median impact factors than cited journals. Conclusion: The findings indicate that the share of international papers, citations and editorial board memberships is low in Iranian ISI journals. Moreover, Iranian journals’ impact factor was below of those of the leading journals.

    2011-03-01

    An inherited skeletal disease with gross and microscopic features of rickets has been diagnosed in Corriedale sheep in New Zealand. The aim of this study was to quantify the changes present in tibia from sheep with inherited rickets using peripheral quantitative computed tomography. In affected sheep, scans in the proximal tibia, where metaphysis becomes diaphysis, showed significantly greater trabecular bone mineral content (BMC) and bone mineral density (BMD). The sheep with inherited rickets had significantly greater BMC and bone area in the mid-diaphysis of the proximal tibia compared to control sheep. However, BMD in the mid-diaphysis was significantly less in affected sheep than in controls, due to the greater cortical area and lower voxel density values in affected sheep. From this it was concluded that the increased strain on under-mineralised bone in sheep with inherited rickets led to increased bone mass in an attempt to improve bone strength.

    2007-08-01

    Full Text Available Abstract Background Active surveillance for transmissible spongiform encephalopathies in small ruminants has been an EU regulatory requirement since 2002. A number of European countries have subsequently reported cases of atypical scrapie, similar to previously published cases from Norway, which have pathological and molecular features distinct from classical scrapie. Most cases have occurred singly in flocks, associated with genotypes considered to be more resistant to classical disease. Experimental transmissibility of such isolates has been reported in certain ovinised transgenic mice, but has not previously been reported in the natural host. Information on the transmissibility of this agent is vital to ensuring that disease control measures are effective and proportionate. Results This report presents the successful experimental transmission, in 378 days, of atypical scrapie to a recipient sheep of homologous genotype with preservation of the pathological and molecular characteristics of the donor. This isolate also transmitted to ovinised transgenic mice (Tg338 with a murine phenotype indistinguishable from that of Nor 98. Conclusion This result strengthens the opinion that these cases result from a distinct strain of scrapie agent, which is potentially transmissible in the natural host under field conditions.

    Full Text Available The aim of this study was to detect the precise sites of the beginning of primary ossification centers of the mandible of sheep fetuses as well as their onset time, to achieve this goal, samples were taken weekly starting from the 7th week up to 20th week of intrauterine life. Sections of the samples were stained by the alizarin red and alcian blue technique. Primary centers appeared at the beginning of 7th week as big red spot on either sides of mesenchyme of first branchial arch (Meckel’s cartilage that developed by intramembranous ossification. The rostral part of the mandible, however, was developed by endochondral ossification. The successive bone development process (7–20 weeks, were moniterd by macerating the mandibles using either potassium hydroxide or fly larvae. Measuring tape and graph papers were employed for measurements and for localization of mandibular angle. The results revealed significant increase of these measurements during the successive weeks of intrauterine life.

    2012-07-01

    Full Text Available Abstract There is a dialogue between the developing conceptus (embryo-fetus and associated placental membranes and maternal uterus which must be established during the peri-implantation period for pregnancy recognition signaling, implantation, regulation of gene expression by uterine epithelial and stromal cells, placentation and exchange of nutrients and gases. The uterus provide a microenvironment in which molecules secreted by uterine epithelia or transported into the uterine lumen represent histotroph required for growth and development of the conceptus and receptivity of the uterus to implantation. Pregnancy recognition signaling mechanisms sustain the functional lifespan of the corpora lutea (CL which produce progesterone, the hormone of pregnancy essential for uterine functions that support implantation and placentation required for a successful outcome of pregnancy. It is within the peri-implantation period that most embryonic deaths occur due to deficiencies attributed to uterine functions or failure of the conceptus to develop appropriately, signal pregnancy recognition and/or undergo implantation and placentation. With proper placentation, the fetal fluids and fetal membranes each have unique functions to ensure hematotrophic and histotrophic nutrition in support of growth and development of the fetus. The endocrine status of the pregnant female and her nutritional status are critical for successful establishment and maintenance of pregnancy. This review addresses the complexity of key mechanisms that are characteristic of successful reproduction in sheep and pigs and gaps in knowledge that must be the subject of research in order to enhance fertility and reproductive health of livestock species.

  20. Lead poisoning in cattle and sheep

    Allcroft, R

    1951-09-15

    The danger of paint and other lead compounds to the bovine is well recognized and has been recorded and discussed fairly extensively from time to time. The literature indicates that the calf is extremely susceptible to lead poisoning, but relatively little has been reported regarding the levels of lead in tissues of animals which have died as a result of lead poisoning, and still less in animals suspected of suffering from sub-lethal doses of lead compounds. In order to provide sufficient data to enable interpretation of figures obtained from tissues in cases of suspected lead poisoning sent in from the field, and to provide information on the metabolic fate of lead in ruminants, investigations were made at Weybridge on the absorption, excretion, retention and general metabolic effects of lead in both cattle and sheep and the results have been published in a series of five papers. In this brief review it is intended to discuss points from these and subsequent investigations which are likely to be of interest to the veterinarian.

  1. Factors of welfare reduction in dairy sheep and goats

    Directory of Open Access Journals (Sweden)

    Antonio Pazzona

    2010-01-01

    Full Text Available Scientific research on factors causing the reduction of well-being in sheep and goats is rather recent, as are studies of strategies to minimize the adverse effects of environmental challenges and improper management practices on flock welfare. Sheep and goats, considered very rustic animals, are reared prevalently under extensive production systems and are widespread mainly in marginal areas. For these reasons, only few studies on the welfare of these species have been carried out in the past. More recently, the scenario has changed, due to a gradual diffusion of intensive and semi-intensive production systems, especially in dairy sheep and goat breeds, to the growing concern of consumers about the life conditions of farmed animals, and to the issuing of a number of rules and laws on the safety of animal products and well-being of farmed livestock. As a consequence, several research groups have turned their attention to the welfare of sheep and goats. Nevertheless, information on this topic is still scarce. This paper reviews major critical points regarding the endangerment of welfare in farmed sheep and goats. Climatic extremes and seasonal fluctuations in herbage amount and quality are discussed as important causes of the reduction of well-being in extensive production systems, which can impair production efficiency of grazing animals and dramatically affect the welfare and health status of sheep and goats. Space allowance and structures of sheep and goat houses are described as the main potential sources of discomfort for housed flocks, together with inadequate control of micro-environment, and inappropriate milking procedures and human-animal interactions. Recent studies on the impact of high ambient temperature, different ventilation regimes, high stocking densities, reduced airspace and poor litter management on behaviour, immune and endocrine response, and on performance of sheep and goats are discussed. The effects of inadequate milking

    The present study aimed at Investigating the knowledge and attitude of Nursing Students towards Iranian Traditional Medicine in universities of Tehran in 2012-2013. 300 students of nursing studying at different universities in Tehran participated in this descriptive, cross-sectional study. The data was collected through a standard questionnaire with an acceptable validity and reliability. The questionnaire was made of five sections including demographic, general knowledge of the Iranian traditional medicine, general attitude towards it, resources of the Iranian traditional medicine and the barriers to it. The results revealed that general knowledge of the students about Iranian traditional medicine and complementary medicine is low. The attitude of the students towards including Iranian traditional medicine and complementary medicine in their curriculum is positive. General attitude of students towards Iranian traditional medicine is positive too. The majority of the participants had not passed any course on Iranian traditional medicine. There was no relationship between participants’ attitude towards Iranian traditional medicine and the number of semesters they had passed. Considering the participants’ positive attitude and their low level of knowledge, it seems necessary for the university policy makers to provide nursing students with different training courses on Iranian traditional medicine and complementary medicine in order to increase their knowledge.

    Full Text Available Abstract Background Some techniques of transvaginal ovarian drilling have been previously described. Nevertheless a monopolar transvaginal ovarian cauterization, that use the expertise and safety of transvaginal puncture for oocyte captation seems to be an easier and feasible approach. The aim of this study was to develop a minimally invasive ovarian cauterization technique under transvaginal ultrasound control, and to evaluate the safety of the transvaginal ovarian monopolar cauterization, female sheep at reproductive age were used as an experimental model. Findings An experimental study was performed in a university research center. Seventeen female sheep (15 Corriedale e 2 Suffolk in reproductive age were submitted to transvaginal ovarian cauterization with a monopolar Valleylab Force 2 electrocautery. Macroscopic and microscopic lesions were assessed. Ovarian size were 1.31 cm2 ± 0,43 (Corriedale and 3.41 cm2 ± 0,64 (Suffolk. From 30 ovaries from Corriedale sheep punctured, only 3 were cauterized, presenting macroscopic and typical microscopic lesion. In the Suffolk sheep group, only one ovary was cauterized. No lesion could be found in the needle path. Conclusions This is the first experimental animal model described for ovarian cauterization needle guided by transvaginal ultrasound. The sheep does not seem to be the ideal animal model to study this technique. Another animal model, whose ovaries are better identified by transvaginal ultrasound should be sought for this technique, theoretically less invasive, before it could be offered safely to women with polycystic ovary syndrome.

    After the detection of arsenic (As) toxicity in sheep from Ebrahim-abad and Babanazar villages in Kurdistan province, the concentration of this element in drinking water, cultivated soil, alfalfa hay, wool, and blood samples was evaluated. Total As concentrations ranged from 119 to 310 μg/L in drinking water, 46.70-819.20 mg/kg in soil 1.90-6.90 mg/kg in vegetation 1.56-10.79 mg/kg in sheep's wool, and 86.30-656 μg/L in blood samples. These very high As contents, in all parts of the biogeochemical cycle, exceed the recommended normal range for this element compared with a control area. Results indicate that As has moved through all compartments of the biogeochemical cycle by way of direct or indirect pathways. The present investigation illustrated decreased packed cell volume and hemoglobin in sheep from the As-contaminated zone. It was concluded that sheep from the contaminated areas suffer from anemia. Chronic As exposure of the liver was determined by liver function tests. For this purpose, blood aspartate transaminase (AST) and alanine transaminase (ALT) were measured. The results show that serum ALT and AST activities are increased significantly (p < 0.01) in the sheep population exposed to As in the contaminated zone. Moreover, chronic As exposure causes injury to hepatocytes and damages the liver.

    Full Text Available Guizhou semi-fine wool sheep are affected by a disease, characterized by emaciation, lameness, stiffness in the gait, enlargement of the costochondral junctions, and abnormal curvature in the long bones. The objective of this study was to determine possible relationships between the disease and mineral deficiencies. Samples of tissue and blood were collected from affected and unaffected sheep. Samples of soil and forage were collected from affected and unaffected areas. The samples were used for biochemical analyses and mineral nutrient measurements. Results showed that phosphorus (P concentrations in forage samples from affected areas were significantly lower than those from unaffected areas (P < 0.01 and the mean ratio of calcium (Ca to P in the affected forage was 12:1. Meanwhile, P concentrations of blood, bone, tooth, and wool from the affected sheep were also significantly lower than those from the unaffected group (P < 0.01. Serum P levels of the affected animals were much lower than those of the unaffected ones, whereas serum alkaline phosphatase levels from the affected were significantly higher than those from the unaffected (P < 0.01. Inorganic P levels of the affected sheep were about half of those in the control group. Oral administration of disodium hydrogen phosphate prevented and cured the disease. The study clearly demonstrated that the disease of Guizhou semi-fine wool sheep was mainly caused by the P deficiency in forage, as a result of fenced pasture and animal habitat fragmentation.

  9. Developing an Ethically Acceptable Virtual Fencing System for Sheep

    2018-02-01

    Full Text Available To ensure animal welfare isn’t compromised when using virtual fencing, animals must be able to associate a benign conditioned stimulus with an aversive stimulus. This study used an associative learning test to train 30, four-year-old, Merino x Suffolk ewes, to associate an audio cue with an electric stimulus. Collars manually controlled by a GPS hand-held unit were used to deliver the audio and electric stimuli cues. For the associative learning, when sheep approached an attractant at a distance of three m from the trough, an audio cue was applied for one s. If the sheep stopped or changed direction, the audio cue ceased immediately and no electrical stimulus was applied. If the sheep did not respond to the audio cue it was followed by a low-level electrical stimulus. Approaches to the attractant significantly decreased from day one to day two. It took a mean of three pairings of the audio cue and electrical stimulus for a change in behaviour to occur, after which sheep that approached the attractant had a 52% probability of avoiding the electrical stimulus and responding to the audio cue alone. Further research is required to determine whether sheep can be trained to associate an audio cue with a negative stimulus for use in group grazing situations.

    Virtual fencing has the potential to greatly improve livestock movement, grazing efficiency, and land management by farmers; however, relatively little work has been done to test the potential of virtual fencing with sheep. Commercial dog training equipment, comprising of a collar and GPS hand-held unit were used to implement a virtual fence in a commercial setting. Six, 5-6 year-old Merino wethers, which were naïve to virtual fencing were GPS tracked for their use of a paddock (80 × 20 m) throughout the experiment. The virtual fence was effective at preventing a small group of sheep from entering the exclusion zone. The probability of a sheep receiving an electrical stimulus following an audio cue was low (19%), and declined over the testing period. It took an average of eight interactions with the fence for an association to be made between the audio and stimulus cue, with all of the animals responding to the audio alone by the third day. Following the removal of the virtual fence, sheep were willing to cross the previous location of the virtual fence after 30 min of being in the paddock. This is an important aspect in the implementation of virtual fencing as a grazing management tool and further enforces that the sheep in this study were able to associate the audio with the virtual fence and not the physical location itself.

    Full Text Available Kinetics of long-acting oxytetracycline (OTC injected intravenously (IV at a dose of 5 mg/kg was determined in each of eight camels, sheep and goats. The disposition of OTC was described by two-compartment open model. Two elimination half-lives were recorded for the camel (81 min and 46.1 h, whereas in sheep and goats these were 3.2 and 3.4 h, respectively. The peak plasma concentration was 10.2, 850 and 780 g/ml at 5 minutes in camel, sheep and goats, respectively. The values of volume of distribution were 1.4, 13.4 and 12.1 litre/kg for the camels, sheep and goats, respectively. In sheep and goats, values of t1/2, Vd and clearance were found similar but different from camel, indicating exclusive distribution and substantial storage which were consistent with oxytetracycline lipophilicity and the large fat content of camel body.

    Full Text Available Since poisoning by Senecio spp. is one of the main causes of cattle death in southern Brazil, control of these plants is a priority for the local livestock production. After the pasture has been mowed, grazing by 16 sheep was efficient for controlling Senecio brasiliensis and Senecio madagascariensis populations in a 5.5-hectare area that had long been severely infested with these species. A total of 28,629 plants among S. brasiliensis (flower-of-souls, 10,122 and S.madagascariensis (fireweed, 18,507 were almost completely eliminated in a two-year period. The number of sheep was kept at 3.0 stock units/ha, but a variable number of cattle were temporarily stocked according to pasture availability. The major sanitary practice applied to the sheep was anthelmintic administration. Liver biopsies taken from sheep and cattle before and after experimental period didn't reveal any change associable with seneciosis. The performance levels of the sheep were comparable to those observed in flocks managed under traditional extensive grazing systems in southern Brazil.

    Izmir is a somewhat privileged case, among the “cosmopolitan” port cities of the Ottoman Eastern Mediterranean, in terms of the number of studies devoted to it. However, although scholars dealing with Izmir’s history almost unanimously cite its cosmopolitan character, most of them examine the city from the perspective of individual ethnic and religious minorities. An obvious disadvantage of such an approach is that it ignores the relational dimension of group formation: minority communities c...

  18. Change in genetic size of small-closed populations: Lessons from a domestic mammal population.

    Ghafouri-Kesbi, Farhad

    2010-10-01

    The aim of this study was to monitor changes in genetic size of a small-closed population of Iranian Zandi sheep, by using pedigree information from animals born between 1991 and 2005. The genetic size was assessed by using measures based on the probability of identity-by-descend of genes (coancestry, f, and effective population size, N(e) ), as well as measures based on probability of gene origin (effective number of founders, f(e) , effective number of founder genomes, f(g) , and effective number of non-founder genomes, f(ne) ). Average coancestry, or the degree of genetic similarity of individuals, increased from 0.81% to 1.44% during the period 1993 to 2005, at the same time that N(e) decreased from 263 to 93. The observed trend for f(e) was irregular throughout the experiment in a way that f(e) was 68, 87, 77, 92, and 80 in 1993, 1996, 1999, 2002, and 2005, respectively. Simultaneously, f(g) , the most informative effective number, decreased from 61 to 35. The index of genetic diversity (GD) which was obtained from estimates of f(g) , decreased about 2% throughout the period studied. In addition, a noticeable reduction was observed in the estimates of f(ne) from 595 in 1993 to 61 in 2005. The higher than 1 ratio of f(e) to f(g) indicated the presence of bottlenecks and genetic drift in the development of this population of Zandi sheep. From 1993 to 1999, f(ne) was much higher than f(e) , thereby indicating that with respect to loss of genetic diversity, the unequal contribution of founders was more important than the random genetic drift in non-founder generations. Subsequently, random genetic drift in non-founder generations was the major reason for f(e) > f(ne) . The minimization of average coancestry in new reproductive individuals was recommended as a means of preserving the population against a further loss in genetic diversity.

    2011-10-01

    This paper discusses the historical development of fat-tailed sheep in Indonesia, the dynamics of production systems, production and reproduction performances under farmers' conditions, and roles of sheep in livelihoods. In the eighteenth and nineteenth century, fat-tailed sheep from southwest Asia and Africander sheep from South Africa were introduced. Crossing of fat-tailed sheep with the local thin-tailed sheep produced the Javanese fat-tailed sheep. Main motives for the gradual change-over to fat-tailed sheep have been their potential larger body size and the preference of consumers for their meat. Management systems are changing in response to the intensification of land use. The reproductive performances of fat-tailed sheep are good. Households keep four to six animals, housed close to the family quarters. This results in very high levels of faecal bacteria contamination of drinking water sources. Sheep provide a small income, manure, security and help to accumulate capital. Sheep also play a key role in religious festivities. Farmers hardly profit from the increased demand for the feast of sacrifice; animals are sold mainly when the owners have urgent cash needs. Systematic sheep fattening can contribute to higher economic results, if sufficient family labour and crop residues are available.

    Full Text Available Maintenance of appropriate levels of fecundity is critical for efficient sheep production. Opportunities to increase sheep litter size include identifying single gene mutations with major effects on ovulation rate and litter size. Whole-genome sequencing (WGS data of 89 Chinese domestic sheep from nine different geographical locations and ten Australian sheep were analyzed to detect new polymorphisms affecting litter size. Comparative genomic analysis of sheep with contrasting litter size detected a novel set of candidate genes. Two SNPs, g.71874104G>A and g.71833755T>C, were genotyped in 760 Small Tail Han sheep and analyzed for association with litter size. The two SNPs were significantly associated with litter size, being in strong linkage disequilibrium in the region 71.80–71.87 Mb. This haplotype block contains one gene that may affect litter size, Histone Cell Cycle Regulator (HIRA. HIRA mRNA levels in sheep with different lambing ability were significantly higher in ovaries of Small Tail Han sheep (high fecundity than in Sunite sheep (low fecundity. Moreover, the expression levels of HIRA in eight tissues of uniparous Small Tail Han sheep were significantly higher than in multiparous Small Tail Han sheep (p < 0.05. HIRA SNPs significantly affect litter size in sheep and are useful as genetic markers for litter size.

    Full Text Available Bluetongue (BT, peste des petits ruminants (PPR and sheep pox are the most economically important viral diseases of sheep in India. Serum samples obtained from sheep in five northern states of the country were screened for antibody against these agents to explore the extent of spread of these infections. A total of 516 serum samples were screened for the presence of antibodies against BT and PPR viruses. Of these, 155 samples were also tested for antibodies against sheep pox virus. BT antibodies were found in 293 (56.8% animals, PPR virus antibodies in 215 (41.7% and sheep pox virus antibodies in 106 (68.3%. Of the serum samples tested, 25.2% were positive for antibodies against all three viruses. These findings clearly demonstrated not only the enzootic nature of disease, but also the co-existence of antibodies to more than one of these viruses which would indicate that concurrent infections were common. Therefore, control measures should focus in combating all three diseases simultaneously by exploring the possibility of a trivalent vaccine or the use of multiple genes expressing vectored vaccine.

    2008-10-01

    Full Text Available Abstract Background Epidemiological studies have used farmer estimates of the prevalence of lameness in their flocks. This assumes that farmers can identify lame sheep. Eight movie clips of sheep with locomotion from sound to moderately lame were used to investigate the ability of farmers and sheep specialists to recognise lame sheep. Each participant was asked to complete a form and indicate, for each movie clip, whether they thought the sheep was lame and whether they would catch it if it was the only lame sheep or if 2 – 5, 6 – 10 or > 10 sheep were equally lame. The farmers' responses were compared with their estimates of flock lameness prevalence and the interval between observing a lame sheep and catching it. Results 178 farmers and 54 sheep specialists participated. Participants could identify even mildly lame sheep but made a separate decision on whether to catch them. This decision was dependent on the severity of lameness and the number of sheep lame in a group. Those who said they would catch the first lame sheep in a group were significantly more likely to catch mildly lame sheep (farmer-reported median prevalence of lameness 5% (IQR: 2%–6%. In contrast, farmers who waited for several sheep to be lame indicated that they would only catch more severely lame sheep (farmer reported median flock lameness 11% (IQR: 9%–15%. Approximately 15% of farmers did not catch individual lame sheep (farmer reported median flock lameness 15% (IQR: 10%–15%. The flock prevalence of lameness increased as time to treatment increased and time to treatment was positively correlated with only catching more severely lame sheep. Conclusion If movie-clips are similar to the flock situation, farmers and specialists can recognise even mildly lame sheep but vary in their management from prompt treatment of the first lame sheep in a group to no individual sheep treatments. The former practices would be appropriate to minimise transmission of footrot, a

    Systemic cladosporiosis is described in 25 merino sheep from a flock consisting 250 animals. The fungal pneumonia appeared after an intensive antibiotic treatment, because of a respiratory system disorder. The pen of the flock was humid and crowded, and animals had signs of respiratory distress, coughing, fever and anorexia. All of the ill animals died, and necropsy was performed on 10 sheep. The lesions were characterized by a multifocal pyogranulomatous pneumonia and an abomasitis. Severe hemorrhages were observed in the lungs. At the histopathological examination, severe vasculitis with thrombosis was observed in various organs, especially in the lungs and abomasums, suggestive for a hematogenous dissemination of the infection in these organs. Numerous PAS-positive fungal elements were seen in the pyogranulomatous foci. Dark green fungal colonies were seen in the blood agar and Sabouraud dextrose agar that were identified as Cladosporium cladosporioides. This report highlights that phaeohyphomycosis can cause a severe systemic and fatal disease in merino sheep under insufficient management conditions.

    Experiments were performed on 6 sheep from 8 months old to study effects of dietary phosphorus depletion on bone structure. Sheep were given a semisynthetic diet of chopped straw and pellets for 38 weeks. Mean daily P in the diet was 0.97 g and 3 sheep were given additional NaH2PO4.H2O, increasing daily P supply to 4.5 g (controls). Bone density was estimated photometrically within the laterodistal metaphysis of the foreleg and standardized by a copper step wedge. Metacarpal cortical thickness was also measured. Cortical thickness and bone density started to decrease about 4 weeks after start of P depletion. The trabecular structure of the distal radius was coarser and less dense with reduced cross-linking between trabeculae

    Grazing behaviours of Teddy goats and Thalli sheep were studied on rangelands of ThaI. Bite count method was used to determine the dietary composition of both animal species. The overall preference of Teddy goats was higher for Khabble grass (Cynodon dactylon), which was 40.57% of the total number of bite made on different plant species during the study period (March-July). Teddy goats utilized a wide range of browsing plant species like Wan (Salvadora oleoides), Phog (Calligonum polygonoides), Babil (Acacia jacquemontii), Jandi (Prosopis spicigera) etc. Browsing species were major component (>50%) of goat diets dur- ing March through June. Whereas Thalli sheep had been consistent in their heavy use of Khabble grass (overall 89.27%). Browsing plant species were not an important component of their diets. Teddy goats and Thalli sheep were competitive for Khabble grass particularly at its vegetative growth stage. (author)

    2009-06-01

    The purpose of this study was to explore the assertiveness process in Iranian nursing leaders. A qualitative design based on the grounded theory approach was used to collect and analyze the assertiveness experiences of 12 nurse managers working in four hospitals in Iran. Purposeful and theoretical sampling methods were employed for the data collection and selection of the participants, and semistructured interviews were held. During the data analysis, 17 categories emerged and these were categorized into three themes: "task generation", "assertiveness behavior", and "executive agents". From the participants' experiences, assertiveness theory emerged as being fundamental to the development of a schematic model describing nursing leadership behaviors. From another aspect, religious beliefs also played a fundamental role in Iranian nursing leadership assertiveness. It was concluded that bringing a change in the current support from top managers and improving self-learning are required in order to enhance the assertiveness of the nursing leaders in Iran.

    Full Text Available Handling stolen goods has been recognized as an independent offence in both Iranian and English law. Committing this offence, tacitly support those actions that are called theft. However, penal policy of Iran’s legislator does not provide effective fighting against the handlers of stolen goods. In others words, comparing the two Iranian and English legal system, make this issue clear that criminalization of stolen goods has some restrictions about physical element as well as the amount of relevant punishment that we can have more effective fighting against supporting factors of larceny with eliminating them and hereto, in the course of exercising appropriate reaction to the handlers, reducing the offence of theft. The article seeks to recommend some solutions for a better penal policy, such as increasing punishment of the offence and extending the scope of its physical behaviour, through comparative analysis of the offence of stolen goods; meanwhile different elements of the offence have been studied.

    Full Text Available Technology of somatic cell nuclear transfer (SCNT has been adapted worldwide to generate transgenic animals, although the traditional procedure relies largely on instrumental micromanipulation. In this study, we used the modified handmade cloning (HMC established in cattle and pig to produce transgenic sheep with elevated levels of omega-3 (n-3 fatty acids. Codon-optimized nematode mfat-1 was inserted into a eukaryotic expression vector and was transferred into the genome of primary ovine fibroblast cells from a male Chinese merino sheep. Reverse transcriptase PCR, gas chromatography, and chromosome analyses were performed to select nuclear donor cells capable of converting omega-6 (n-6 into n-3 fatty acids. Blastocysts developed after 7 days of in vitro culture were surgically transplanted into the uterus of female ovine recipients of a local sheep breed in Xinjiang. For the HMC, approximately 8.9% (n  =925 of reconstructed embryos developed to the blastocyst stage. Four recipients became pregnant after 53 blastocysts were transplanted into 29 naturally cycling females, and a total of 3 live transgenic lambs were produced. Detailed analyses on one of the transgenic lambs revealed a single integration of the modified nematode mfat-1 gene at sheep chromosome 5. The transgenic sheep expressed functional n-3 fatty acid desaturase, accompanied by more than 2-folds reduction of n-6/n-3 ratio in the muscle (p<0.01 and other major organs/tissues (p<0.05. To our knowledge, this is the first report of transgenic sheep produced by the HMC. Compared to the traditional SCNT method, HMC showed an equivalent efficiency but proved cheaper and easier in operation.

    During the past century extensive uranium mining took place in Portugal for radium and uranium production. Many uranium deposits were mined as open pits and after ore extraction and transportation to milling facilities, mining wastes were left on site. One uranium ore mining site, Boco Mine, was extracted in the 1960's and 70's and mining waste and open pits were left uncovered and non-remediated since closure of uranium mining activities. During the nineties a quarry for sand extraction was operated in the same site and water from a local stream was extensively used in sand sieving. Downstream the mine areas, agriculture soils along the water course are currently used for cattle grazing. Water from this stream, and water wells, soil, pasture and sheep meat were analyzed for radionuclides of the uranium series. The U- series radionuclide {sup 226}Ra was generally the highest in concentrations especially in soil, pasture, and in internal organs of sheep. Ra-226 concentrations averaged 1093±96 Bq/kg (dry weight) in soil, 43±3 Bq/kg (dw) in pasture, and 0.76±0.41 Bq/kg (dw) in muscle tissue of sheep grown there. Other sheep internal organs displayed much higher {sup 226}Ra concentrations, such as the brain and kidneys with 7.7±2.3 Bq/kg (dw) and 28±29 Bq/kg (dw), respectively. Results of tissue sample analysis for sheep grown in a comparison area were 2 to 11 times lower, depending on the tissue. Absorbed radiation doses for internal organs of sheep were computed and may exceed 20 mSv/y in the kidney. Although elevated, this absorbed radiation dose still is below the threshold for biological effects on mammals. Nevertheless, enhanced environmental radioactive contamination mainly due to radium was observed in the area of influence of this legacy uranium mine and there is potential food chain transfer for humans (authors)

    Mastitis is the most prevalent disease in dairy sheep with major economic, hygienic and welfare implications. The disease persists in all dairy sheep production systems despite the implementation of improved management practises. Selective breeding for enhanced mastitis resistance may provide the means to further control the disease. In the present study, we investigated the genetic architecture of four mastitis traits in dairy sheep. Individual animal records for clinical mastitis occurrence and three mastitis indicator traits (milk somatic cell count, total viable bacterial count in milk and the California mastitis test) were collected monthly throughout lactation for 609 ewes of the Greek Chios breed. All animals were genotyped with a custom-made 960-single nucleotide polymorphism (SNP) DNA array based on markers located in quantitative trait loci (QTL) regions for mastitis resistance previously detected in three other distinct dairy sheep populations. Heritable variation and strong positive genetic correlations were estimated for clinical mastitis occurrence and the three mastitis indicator traits. SNP markers significantly associated with these mastitis traits were confirmed on chromosomes 2, 3, 5, 16 and 19. We identified pathways, molecular interaction networks and functional gene clusters for mastitis resistance. Candidate genes within the detected regions were identified based upon analysis of an ovine transcriptional atlas and transcriptome data derived from milk somatic cells. Relevant candidate genes implicated in innate immunity included SOCS2, CTLA4, C6, C7, C9, PTGER4, DAB2, CARD6, OSMR, PLXNC1, IDH1, ICOS, FYB, and LYFR. The results confirmed the presence of animal genetic variability in mastitis resistance and identified genomic regions associated with specific mastitis traits in the Chios sheep. The conserved genetic architecture of mastitis resistance between distinct dairy sheep breeds suggests that across-breed selection programmes would be

    Full Text Available The purpose of the study was to determine microbial contamination of mutton carcass surface with regard to the number of the slaughtered animals. The total bacterial load and Enterobacteriaceae and enterococci counts were determined. Sampling for microbiological analysis as well as detection and enumeration of each microorganism group were performed according to the Polish Standards. No significant effect of the order of the slaughtering animals during the slaughter day on total bacterial count on mutton carcass surfaces was found. The overall bacterial contamination of mutton carcasses were between 1.0 × 103 cfu/cm2 (3.0 log - stage I and 2.5 × 103 cfu/cm2 (3.4 log - stage III. No significant difference among the slaughter cycles, as indicated by total microbial numbers was observed. The obtained daily mean log values ranged from 4.7 × 102 (2.67 log and 7.6 × 103 (3.88 log cfu/cm2. The daily log mean values were lower than the maximal bacteria count (M set out for hygiene standard of sheep slaughter process by the Commission Regulation 2073/2005. Bacteria belonging to the Enterobacteriaceae family were recovered from 21 (65.6% samples while enterococci were identified in 28 (87.5% samples. In most cases, significant differences in the level of contamination with bacteria isolated from the carcasses at each stage of a daily slaughter cycle, were not observed. At stage III, significantly higher levels of bacterial contamination (0.86 and 1.31 log cfu/cm2 respectively were established as compared to stage I (0.37 and 0.58 log cfu/cm2 respectively. There were no Salmonella-positive samples determined. Importantly, the number of slaughtered animals during a slaughter day did not influence bacterial contamination on carcass surface if the successful application of HACCP control system was combined with the implementation of optimal sanitary supervision.

    Context: Functional dyspepsia (FD) is a functional gastro-intestinal disorder with high prevalence. Among various treatment options, treatment by complementary and alternative medicines especially herbal remedies also practiced. Traditional Iranian medicine (TIM), a valuable resource of valid applied studies of ancient Iranian scholars, recommends numerous medicinal plants to treat dyspepsia symptoms. In this study, through investigation of TIM references, we aimed to identify medicinal plants for treatment of digestion insufficiency. Evidence Acquisition: In this qualitative study, dyspepsia symptoms including fullness, early satiety, bloating, nausea, and belching were checked under reliable sources of traditional medicine. Then medicinal plants recommended for the treatment of the symptoms were extracted from the books. Likewise, for investigating the pharmacological properties of medicinal plants used for the relieving of dyspepsia symptoms, electronic databases such as PubMed, Scopus, Google Scholar and some Iranian databases like SID and IranMedex were employed. Results: The study yielded 105 plants from 37 families which could treat various dyspepsia symptoms; fifty-seven plants, mainly from Apiaceae, Lamiaceae, Amaryllidaceae and Zingiberaceae had digestive effects. In this research, based on the information in TIM reference texts, we obtained 58 plants effective for bloating, 40 for nausea, 37 for appetite loss and 7 for belching. In human clinical trials conducted on medicinal plants effective for FD symptoms, 7 single plants were used. Conclusions: Finding the medicinal plants effective on digestion insufficiency based on TIM could suggest a better strategy for the relieving of dyspepsia symptoms. Traditional Iranian medicine prescribes medicinal plants based on each patient’s personal characteristics and practices multiple target therapies. PMID:26734483

    2016-03-01

    Full Text Available Background Melasma (called Kalaf in Iranian traditional medicine is a common acquired hypermelanosis that affects sun-exposed areas of skin. Several factors including exposure to sunlight, pregnancy, and endocrine diseases increase the risk for Melasma. In traditional medicine, antecedent philosophers and physicians have tried to understand the nature and mechanisms of different systems of the human body for the diagnosis and management of Melasma; they have offered different solutions for it. This study is important since Melasma is a disease causing mental side effects in patients, due to darkness and opacity of the skin; therefore, the treatment of Melasma in terms of its psychological complications is of particular importance. In addition, texts of Iranian traditional medicine contain a wealth of nutritional advice for patients with Melasma. These texts have, until now, not yet been reviewed. The present study has considered the most important references of Iranian traditional medicine texts. Objectives The objective of this study was to extract and categorize the nutritional advice of Iranian traditional medicine texts for the treatment of Melasma. Results Dietary recommendations, not only for treatment but also for prevention of diseases and staying healthy, are very efficient. Conclusions Based on the traditional medicine texts, it is helpful to avoid Soda-producing food as well as to identify appropriate food in order to eliminate the accumulation of Soda or black bile from the blood. This study offers a set of analytical and clinical research on food, which in traditional medicine is called Soda-producing as well as Soda reducing.

    Full Text Available Objectives: Emotion regulations refer to the ability of experiencing emotions as a basic human capacity and the experience of the basic emotions happiness, anger, sadness and fear are considered as reular characteristics among nations. In school-age children, problems in socioemotional development typically shows themselves as challenging, socially disruptive paterns of behavior. The purpose of the present study was to understand Emotion Regulation characteristics in Iranian primary school pupils and whether Iranian children enable to identify common emotions. Methods: Participants included 900 children, 9 to 10 years, from elementary schools from 21 provinces in Iran. In pilot work we presented 200 children with four hypothetical vignettes of the kind typically used in display rule research. In the main study children’s knowledge regarding hiding their emotions was assessed through a structured interview. The participants were presented with the interview questions after the vignettes. The answers were coded by two people and the interrater reliability was high. The children were assessed on the basis of four common emotions:Happiness, Anger,Fear,and, Sadness. Results: The analysis of the data indicated that: 1 all children were enabled to identify and differentiate all four emotions from each other, most of students hide their happiness, anger, fear and sadness, they hide their emotions in specific situation such as school and home, hide happiness and anger against peers and hide fear and sadness in front of adults. Discussion: The study indicates that Iranian children not only differ from other culture peers in the amount of display rule use in daily life, but also in the situations they report using it and their motives for doing so they suppress their overall emotions more frequently, especially in presence of family and for pro-social and self-protective reasons. These findings provides the basic knowledge about Iranian children

    On November 4, 1979, Iranian revolutionaries seized the American embassy in Tehran and took hostage 66 American diplomats and citizens. In the midst of the massive national celebration sparked by the eventual release of the hostages, commentators started to ask sobering questions: Why did the crisis become such an obsession with the American people? How did this public obsession affect policymakers? And was there really a cause for celebration? The subject of my thesis is the American pub...

    Full Text Available Derived from the emerging paradigm shift in English language teaching and assessment, there has been a renewal of interest in dynamic assessment (DA to be used as an alternative to the traditional static testing in language classrooms. However, to date, DA practice has been mostly limited to clinical treatments of children with learning disabilities, and it has not been widely incorporated into the EFL contexts. In order to find out the reasons behind the slow trend of DA practice, this research adopted a framework, based on the post method pedagogical principles and recommendations, to delve into the prospect of methodological realization of DA approaches in Iranian EFL classrooms. To this end, two instruments, a questionnaire and an interview were developed to explore the practicality of DA through seeking 51 Iranian EFL teachers' perception of DA practice in their classrooms. The results indicated that most of the teachers were negative about the practice of DA in their classrooms and believed that a full-fledged implementation of DA in Iranian EFL classrooms is too demanding. The feasibility of DA in Iranian EFL classrooms, where teachers are deprived of DA training, guideline, and technological resources, is questioned seriously due to the factors such as time-constrained nature of DA procedures, large number of students in EFL classrooms, the common practice of static tests as the mainstream, and overreliance on the teachers' teaching and assessment abilities. The paper suggests the framework of inquiry in this study, which was derived from the post method pedagogy, to be utilized as a blueprint for a critical appraisal of any alternative method or theory which is introduced into ELT contexts.

    Various practical methods have been used for pregnancy diagnosis in sheep: radiography, rectal abdominal palpation, assessment of progesterone, assessment of estrone sulphate, RIA assay of placental lactogen, assessment of pregnancy proteins or pregnancy-associated glycoproteins, A-mode ultrasound, Doppler ultrasound and real-time B-mode ultrasonography. Real-time, B-mode ultrasonography appears to be the most practical and accurate method for diagnosing pregnancy and determining fetal numbers in sheep. Transabdominal B-mode ultrasonography achieved high accuracy for pregnancy diagnosis (94-100 %) and the determination of fetal numbers (92-99 %) on d 29 to 106 of gestation

    2015-12-01

    Full Text Available New tests of animal affect and welfare require validation in subjects experiencing putatively different states. Pharmacological manipulations of affective state are advantageous because they can be administered in a standardised fashion, and the duration of their action can be established and tailored to suit the length of a particular test. To this end, the current study aimed to evaluate a pharmacological model of high and low anxiety in an important agricultural and laboratory species, the sheep. Thirty-five 8-month-old female sheep received either an intramuscular injection of the putatively anxiogenic drug 1-(m-chlorophenylpiperazine (mCPP; 1 mg/kg; n = 12, an intravenous injection of the putatively anxiolytic drug diazepam (0.1 mg/kg; n = 12, or acted as a control (saline intramuscular injection n = 11. Thirty minutes after the treatments, sheep were individually exposed to a variety of tests assessing their general movement, performance in a ‘runway task’ (moving down a raceway for a food reward, response to startle, and behaviour in isolation. A test to assess feeding motivation was performed 2 days later following administration of the drugs to the same animals in the same manner. The mCPP sheep had poorer performance in the two runway tasks (6.8 and 7.7 × slower respectively than control group; p < 0.001, a greater startle response (1.4 vs. 0.6; p = 0.02, a higher level of movement during isolation (9.1 steps vs. 5.4; p < 0.001, and a lower feeding motivation (1.8 × slower; p < 0.001 than the control group, all of which act as indicators of anxiety. These results show that mCPP is an effective pharmacological model of high anxiety in sheep. Comparatively, the sheep treated with diazepam did not display any differences compared to the control sheep. Thus we suggest that mCPP is an effective treatment to validate future tests aimed at assessing anxiety in sheep, and that future studies should include other subtle indicators of

    The sheep ked Melophagus ovinus is a member of the parasitic Dipteran family Hippoboscidae; it was a widespread ectoparasite of sheep that was of veterinary importance until the introduction of effective pesticides. Since then it has become of less concern and may have become a relatively uncommon species through much of its former range. Changes in agricultural practice, both greater intensification and development of more extensive systems (including organic farming and conservation grazing), may allow resurgence and a review of existing knowledge of M. ovinus may be timely. This paper reviews the biology, annual population cycles, natural causes of mortality, veterinary and economic significance and control of, and host resistance to, M. ovinus.

    Full Text Available There are a number of medicinal combinations in the Iranian traditional medicine which are commonly used as tonic for liver. In this review, we have introduced some medicinal plants that are used mainly for the treatment of liver disorders in Iranian folk medicine, with focus on their hepatoprotective effects particularly against CC14 agent. In this study, online databases including Web of Science, PubMed, Scopus, and Science Direct were searched for papers published from January 1970 to December 2013. Search terms consisted of medicinal plants, traditional medicine, folk medicine, hepatoprotective, Iran, liver, therapeutic uses, compounds, antioxidant, CC14, anti-inflammatory, and antihepatotoxic, hepatitis, alone or in combination. Allium hirtifolium Boiss., Apium graveolens L., Cynara scolymus, Berberis vulgaris L., Calendula officinalis, Nigella sativa L., Taraxacum officinale, Tragopogon porrifolius, Prangos ferulacea L., Allium sativum, Marrubium vulgare, Ammi majus L., Citrullus lanatus Thunb, Agrimonia eupatoria L. and Prunus armeniaca L. are some of the medicinal plants that have been used for the treatment of liver disorders in Iranian folk medicine. Out of several leads obtained from plants containing potential hepatoprotective agents, silymarin, β-sitosterol, betalain, neoandrographolide, phyllanthin, andrographolide, curcumin, picroside, hypophyllanthin, kutkoside, and glycyrrhizin have been demonstrated to have potent hepatoprotective properties. Despite encouraging data on possibility of new discoveries in the near future, the evidence on treating viral hepatitis or other chronic liver diseases by herbal medications is not adequate.

    Full Text Available Extensive studies in the fields of culture and parenting in recent years have shown that parent’s goals and values of parenting lead to differences in their parental behaviors. This study was designed to observe Iranian mothers’ interaction with their children in a playing situation. This study was a qualitative study in which 30 pairs of mothers and children (15 girls and 15 boys were selected purposely. To observe the parent-child interaction, a playing situation was designed and recorded by video camera. Observational data were analyzed based on qualitative analysis methods. Through coding and categorizing the observed data of the parent-child interaction, verbal (positive, negative and facilitator and nonverbal (positive, negative and communicative behavioral patterns were extracted and named by the investigator. Based on scoring the determined codes, facilitator verbal behaviors and negative nonverbal behaviors were the most frequent. The mothers’ behavior that facilitated child’s playing process and diminished child’s practical and mental activities were named facilitator behaviors, and were the most frequent among Iranian mothers. Based on the same previous research, Iranian mothers’ parenting behaviors are similar to those of Japanese, Chinese and Latin mothers rather than American, British and Australian mothers.

  12. Cyber meets nuclear - Stuxnet and the cyberattacks on Iranian centrifuges

    In 2010 the computer worm Stuxnet attacked the information hardware of the Iranian uranium enrichment program. Stuxnet spread by USB flash drives and attacked SCADA software installed on Windows systems via several zero-day exploits. SCADA configures programmable logic controllers which control in the case of the Iranian centrifuge cascades frequency converter drives to choose the frequency of centrifuge motors. Thus the attackers were able to either change the rotation frequency of the rotor and thereby the separative power of the centrifuge or even destroy the fast spinning centrifuges by stopping and restarting them. The designers of Stuxnet must have had intimate knowledge of the facility design as e.g. the cascade connection scheme was programmed into Stuxnet. Based on this information some calculations of the Iranian cascade regarding the potential to produce highly enriched uranium will be presented using cascade simulation tools. The use of such highly sophisticated computer attacks to sabotage a nuclear program shed a new light on the debate about cyber attacks and the use of information technology for kinetic attacks in general. The talk will address problems the weaponization of information technology poses for international security and will highlight some more recent developments.

    Full Text Available Ever since 2002 relations between the West and Israel on the one hand and Iran on the other have been deteriorating due to the contentious issue of Iranian nuclear programme. Israel and the US have been claiming that there has been a secret Iranian nuclear weapons program, on the grounds that Iran has persisted in its effort to acquire independent uranium enrichment capability and has since 2006 allowed only limited inspections by the International Atomic Energy Agency. Iran has been claiming that its nuclear program is entirely peaceful. Today, one certainly cannot exclude possibility of a military attack on Iranian nuclear facilities. However, one cannot properly understand the problem without taking into account the historical and structural dimensions. Namely, Iran's nuclear policy has been guided by country's determination that it will become independent and self-reliant in every possible field – a result of its very negative historical experience. Thus, Iran has been determined to fully exercise its right to peaceful nuclear development, to which it is entitled according to the Treaty on the Non-Proliferation of Nuclear Weapons. Iran has been striving to overcome the structural dependence of developing countries in the field of nuclear energy, as they have been denied the possibility of comprehensive nuclear development for peaceful purposes by countries possessing developed nuclear industries. The latter have prevented balanced implementation of the Treaty on the Non-Proliferation of Nuclear Weapons.

    Full Text Available In post-Soviet period Russia and Iran have experienced quite a few sharp turns in bilateral relations. Periods of active dialogue alternated with long pauses, signing of multibillion-dollar contracts was replaced by the prosecution of both parties in default of its obligations and commitments. Geopolitical interests in this case take precedence over economic ones. The article describes the role of the Iranian issue in Russian-US relations, both within the Gore-Chernomyrdin Commission and concerning Iranian nuclear program. The question of the legal status of the Caspian Sea also affects bilateral relations. However, there are a number of objective factors that bring together country. Among them is a need to combat ethnic separatism as well as shock economic reforms started almost simultaneously in Russia and Iran in the early 1990s and led to an increase in social tension. Both countries are interested in maintaining peace and stability in the former Soviet republics of Central Asia, Caucasus and Afghanistan. In July 2005, Iran received observer status at the Shanghai Cooperation Organization (SCO. With the return to the post of Russian president Vladimir Putin in 2012, there has been improvement in Russian-Iranian relations. There has been a number of positive trends in trade and economic relations, implementation of joint economic projects.

    Full Text Available Islamic Revolution and the consequent Islamic state in Iran have revived Iranian-Islamic civilization’s discourse in a modern form which is rooted in both Iranian and Islamic ancient civilizations. Post-revolutionary Iran, as an obviously determinant country in this civilizational field, which has developed the civilization in the modern era, necessarily has to think and act civilizationally in order to resist western Humanist and Materialist affects. Academy is the place within which knowledge, as clearly one of the most important foundations of civilization-building, is produced. Civilization-building is the horizon toward which Iranian Universities should orient themselves. Academy is the canon of science, knowledge, and culture, and therefore plays an affective role in the formation, development and flourishing of a civilization; and it could be said that University is the foundation on which civilization is built. In other words, University in the modern era is not only the site of education and research, but also as an epistemological basis, participates in the process of culture and civilization-building; the matter which this study attempts to elaborate. Thus, we attempt to explain and define the necessary tools and indicators in the process.

    Full Text Available Academicians are identified with their papers and expertise in writing scholarly articles, either for promotion or for satisfying their prestige. Iranian academic members are expected to win a justifiable stance by the quality and quantity of their publications and presentations. Regrettably through pervious studying about second language writing, any studies haven’t been dedicated to the style of writing articles, which are used by academic members. Former studies on second language writing indicate that style in academic paper writing is most likely ignored. The purpose of this study is to explore the role of mind translation strategy among Iranian academic members for expressing their own opinion through writing second language academic papers. The present paper has based its hypothesis on three levels of strategies, effective in writing academic papers, namely: 1-Do Iranian academicians follow specific strategies in writing their academic papers? 2-What role does translation play as a strategy in their writing academic papers? 3-Do they feel a need for a strategy shift in their academic paper writing? Data elicited based on survey and corpora analysis in form of CBDTS- on micro and macro levels, are put into matrices and their analyses are supportive of academicians’ reliance on different types of mental translation use and their shift toward authentic writing after receiving feedback from their reviewers.

    Full Text Available Iran together with Afghanistan is the third largest producer and exporter of cashmere in the world, after China and Mongolia. This paper assesses the status of cashmere marketing of Iran in order to evaluate sustainability, and to identify some constraints limiting the productivity and compa-tibility. In August to December 2011 structured questionnaires and interviews were used to compile information regarding market chains cashmere industry of Iran. Information compiled revealed that nearly all the cashmere was marketed by direct buying in Iran. The principle centers for the gathering and rough sorting raw cashmere in Iran were Baft, Sirjan, Mashad, and Birjand. The principle cashmere-importing countries of Iranian cashmere were China, England, Belgium and Italy. The price for Iranian cashmere has showed large fluctuations in the last forty years: it increased from 25 dollars in 1972 to 110 dollars in 1988 and decreased to 65 dollars in 2006 and again increased to 110 dollars in 2012. Given the present status of production and marketing there seems to be substantial scope to improve the value addition of Iranian cashmere.

    Bighorn sheep (BHS, Ovis canadensis) are much more susceptible than domestic sheep (DS, Ovis aries) to pneumonia caused by leukotoxin (Lkt)-producing members of the Family Pasteurellaceae, particularly Mannheimia haemolytica and Bibersteinia trehalosi. Leukotoxin is widely accepted as the critical virulence factor of these bacteria since Lkt-negative mutants do not cause death of BHS. Typically, DS carry Lkt-positive M. haemolytica and/or B. trehalosi as commensal bacteria in their nasopharynx. In contrast, most BHS do not carry Lkt-positive M. haemolytica or B. trehalosi, or carry Lkt-negative strains in their nasopharynx. In previous studies, we demonstrated that unimmunized DS resist M. haemolytica challenge while BHS succumb to it. We hypothesized that Lkt-neutralizing antibodies, induced by Lkt-positive M. haemolytica and/or B. trehalosi innately carried by DS in their nasopharynx, render them less susceptible to infection by these bacteria. In this study we developed BHS×DS F1 hybrids by artificial insemination of domestic ewes with BHS semen. F1 hybrids were fertile, and produced F2 hybrids and back-crosses. The F1, F2, and back-crosses were raised together with domestic ewes. All these animals acquired Lkt-positive M. haemolytica and/or B. trehalosi, and developed high titers of Lkt-neutralizing antibodies in the absence of vaccination. Furthermore, all of these animals resisted challenge with lethal dose of M. haemolytica. These results suggest that lack of previous exposure to Lkt is at least partially responsible for fatal pneumonia in BHS when they acquire Lkt-positive M. haemolytica and/or B. trehalosi from DS when the two species commingle.

    Full Text Available Burnout is one of the potential threats to teachers which can negatively influence their performance and bring about many side effects such as poor health conditions, depression, absenteeism, etc. It has, however, been found teachers who use effective coping strategies to deal with stressful job conditions can resist burnout. This qualitative design study aimed to investigate the coping strategies of 15 Iranian high school EFL teachers who did not show burnout on Maslach Burnout Inventory. The participants were interviewed and observed in classrooms and they were asked to keep journals for 8 sessions. The data were content analyzed and results show that establishment of rapport with students, discussing problems with principals and colleagues, class management, reflection, ongoing learning, adherence to moral principles and adopting a traditional teaching style are among the coping strategies these teachers used. The low frequency of these strategies, however, implies that EFL teachers, even those who resist burnout, need to be trained on different burnout coping strategies.

    Although sheep (Ovis aries) have been one of the most exploited domestic animals in Estonia since the Late Bronze Age, relatively little is known about their genetic history. Here, we explore temporal changes in Estonian sheep populations and their mitochondrial genetic diversity over the last 3000 years. We target a 558 base pair fragment of the mitochondrial hypervariable region in 115 ancient sheep from 71 sites in Estonia (c. 1200 BC–AD 1900s), 19 ancient samples from Latvia, Russia, Poland and Greece (6800 BC–AD 1700), as well as 44 samples of modern Kihnu native sheep breed. Our analyses revealed: (1) 49 mitochondrial haplotypes, associated with sheep haplogroups A and B; (2) high haplotype diversity in Estonian ancient sheep; (3) continuity in mtDNA haplotypes through time; (4) possible population expansion during the first centuries of the Middle Ages (associated with the establishment of the new power regime related to 13th century crusades); (5) significant difference in genetic diversity between ancient populations and modern native sheep, in agreement with the beginning of large-scale breeding in the 19th century and population decline in local sheep. Overall, our results suggest that in spite of the observed fluctuations in ancient sheep populations, and changes in the natural and historical conditions, the utilisation of local sheep has been constant in the territory of Estonia, displaying matrilineal continuity from the Middle Bronze Age through the Modern Period, and into modern native sheep.

    Full Text Available Erodium moschatum is an exotic weed in the southern and southwestern coastal areas of the Western Cape Province (WCP, South Africa. It has been suspected as the cause of photosensitivity in sheep. However, attempts to induce photosensitivity by dosing it to sheep have thus far been unsuccessful. During August 1999, 2 sheep suffering from severe photosensitivity were presented for clinical examination to the Western Cape Provincial Veterinary Laboratory (WCPVL. One sheep was sacrificed for autopsy. Except for skin lesions associated with photosensitivity, no icterus or other lesions were present. Histopathological examination of affected skin revealed epidermal necrosis while the liver had no microscopic lesions. It was therefore concluded that the sheep might have been suffering from primary photosensitivity. The farmfrom which the sheep came, situated in the Malmesbury district, WCP, was visited to determine the source of the photodynamic agent. The flock from which the sheep originated had been grazing in a camp where E. moschatum was growing abundantly and had been heavily grazed. Some remaining Erodium in the camp was collected, pulped and dosed over a period of 7 days to an adult sheep. Another sheep was dosed simultaneously with Erodium growing on the premises of the WCPVL. Both sheep developed mild photosensitivity, which was confirmed by histopathological examination of skin biopsies. It was concluded that E. moschatum can induce photosensitivity (probably the primary type in sheep if ingested in large quantities.

    Full Text Available AIM: To investigate whether single-dose intravitreal injections of bevacizumab and ranibizumab transfer into milk. METHODS: This study included lactating 12 sheep and a single 3-month old suckling lamb of each sheep. Two groups consisting of 6 sheep and their lambs were constituted; the ranibizumab group and the bevacizumab group before the administration of intravitreal injections, blood and milk samples were obtained from all sheep and, following the injections, blood and milk samples of all sheep and blood samples of all lambs were collected at regular time points. Serum and milk concentrations of bevacizumab and ranibizumab were measured using an enzyme-linked immunosorbent assay (ELISA kit. The limit of determination was 0.9 ng/mL for bevacizumab and 0.62 ng/mL for ranibizumab. RESULTS: At 6h after intravitreal injections, bevacizumab concentration was above the limit of determination in the blood of all sheep. At 3wk, when the study was terminated, bevacizumab concentrations were high in 4 sheep. Even though bevacizumab concentrations in milk showed fluctuations, the drug transferred into the milk of all sheep at detectable concentrations. Ranibizumab drug concentrations in the blood and milk of sheep and those in the blood of lambs were below the limit of determination by the ELISA kit. CONCLUSION: This sheep model study demonstrate that intravitreal injection of ranibizumab, which did not transfer into the milk of sheep and suckling lambs, is safer than bevacizumab during lactation period.

    Quoting an article in well-known textbooks is held as a credit for that paper. The numbers of Iranian publications mentioned in endodontic textbooks have increased during recent years. The aim of this investigation was to evaluate the number of Iranian articles quoted in eminent endodontic textbooks. Three known textbooks (Ingle's Endodontics, Seltzer and Bender's Dental Pulp and Cohen's Pathways of the Pulp) were chosen and all the editions of the textbooks since 2000 were investigated for quoted Iranian publications. Only Iranian authors with affiliations from a domestic university were chosen. All references at the end of each chapter were read by hand searching, and results were noted. The trend and percentage of Iranian publications in different editions of the textbooks were also calculated. The number of citations of these publications in Google Scholar and Scopus databases were also obtained. The number of Iranian publications in all well-known textbooks have notably increased since 2000. The number and percentage of Iranian publications in the latest edition of Cohen's Pathways of the Pulp was higher compared to other textbooks as well as the previous edition of the same text. Number and percentage of Iranian publications in the field of endodontics in all three textbooks have remarkably increased since 2000.

    1988-10-01

    Bighorn sheep were inoculated intratracheally with suspensions of nonhemolytic Pasteurella haemolytica biotype T (10(12) organisms) unique to wild bighorns, with beta-hemolytic P. haemolytica biotype T (10(12) organisms) isolated from clinically normal domestic sheep or intradermally with half a dose of a cattle vaccine containing P. haemolytica biotype A (10(5) organisms). The bighorn strain caused lobar necrotizing bronchopneumonia whereas both domestic livestock strains precipitated fatal septicemia and fibrinous bronchopneumonia. The serotypes given were T3, T4, T15 and A1 and these were recovered from lung lesions and other organs. In three trials, domestic sheep were inoculated intratracheally with suspensions of bighorn sheep pneumonic lungs, and two concentrations of the P. haemolytica bighorn strain (10(4) and 10(12) organisms). One of these sheep was inoculated intrabronchially. The domestic sheep experienced a transient fever and elevated white blood cell counts. After six days, none of the sheep had lung lesions and inoculated organisms could not be recovered. It is suggested that bighorn sheep are very susceptible to P. haemolytica from domestic livestock and should not be allowed in contact with sheep or cattle.

    2008-10-01

    This study examined the relationship between three mental health constructs and perceived cultural attitudes toward homosexuality among lesbian, gay, and bisexual individuals. Specifically, differences in perceived cultural attitudes and depression, self-esteem, and perceived stress between 49 Iranians and 47 Americans were compared. It was hypothesized that (a) perceived cultural attitudes toward homosexuality would be more negative among Iranians than Americans; (b) perceived cultural attitudes would be related to depression, self-esteem, and perceived stress; and (c) that Iranian participants' scores on the depression, self-esteem, and perceived stress measures would reflect poorer mental health than that of their American counterparts. Results indicated more negative perceptions of cultural attitudes toward homosexuality among Iranians. Contrary to prediction, however, no difference was found in levels of depression, self-esteem, and perceived stress among American and Iranian participants. Findings are discussed in terms of cultural and familial differences with regard to sexual orientation disclosure.

    Full Text Available Istrian dairy sheep is a local breed essential for the identity and development of the Northern- Adriatic karstic region through high-quality products, primarily the hard sheep artisanal cheese. Border changes fragmented the initial Istrian dairy sheep population in three genetically isolated sub-populations in Italy (1000 animals, Slovenia (1150 animals and Croatia (2500 animals. Due to the drastic reduction of their population sizes and fragmentation, the populations in Croatia and Slovenia are included in governmentally supported conservation programs. The initial subpopulation in Italy was restored after near extinction with stock from Slovenia, and is used today in meat production. The aim of this study was to provide an initial understanding of the current genetic structure and distribution of the genetic variability that exists in Istrian sheep by analysing individuals sampled in two regional groups of Istrian sheep from Croatia and Slovenia. Cres island sheep and Lika pramenka sheep were used as out-groups for comparison. Genetic differentiation was analysed using factorial correspondence analysis and structure clustering over 26 microsatellite loci for a total of 104 sheep belonging to three breeds from Croatia and Slovenia. Factorial correspondence analysis and clustering-based structure analysis both showed three distinct populations: Lika pramenka sheep, Cres island sheep and Istrian sheep. We did not find a marked genetic divergence of the regional groups of Istrian sheep. Istrian sheep regional group from Slovenia showed lower genetic variability compared to the one from Croatia. Variability and structure information obtained in this study considered alongside with socio-cultural-contexts and economic goals for the Istrian sheep reared in Croatia and Slovenia indicate that the cross-border exchange of genetic material of animals carrying private alleles among populations would maintain these alleles at low frequencies and minimize

    Full Text Available Sheep play an important role in national economy and social economy in rural areas in Iran. The main goal of this study was to investigate the fauna and frequency of parasitic helminth infections prevalent in native sheep in Hamedan, western Iran. From April 2010 to March 2011, the gastrointestinal and respiratory tracts of 100-sheep were examined using conventional parasitological methods. The overall infection rate was found as 69%. No infection was found in esophagus and rumens. Parabronema skerjabini (22% and Ostertagia circumcincta (1% were recorded as the maximum and minimum cases for the presence of nematode, respectively. On the other hand, the most dominant of trematode and cestode were Fasciola hepatica (13% and Monezia expansa (13%, respectively. The highest infection rate was reported in summer (84%. The prevalence of helminth infection was varied among gender, seasons and age groups. In conclusion, this is the first report of parasitic helminth infections in sheep in Hamedan province in western Iran. Our results provide baseline information for the future studies.

    Full Text Available Commercial sheep raised for mutton grow faster than traditional Chinese sheep breeds. Here, we aimed to evaluate genetic selection among three different types of sheep breed: two well-known commercial mutton breeds and one indigenous Chinese breed.We first combined locus-specific branch lengths and di statistical methods to detect candidate regions targeted by selection in the three different populations. The results showed that the genetic distances reached at least medium divergence for each pairwise combination. We found these two methods were highly correlated, and identified many growth-related candidate genes undergoing artificial selection. For production traits, APOBR and FTO are associated with body mass index. For meat traits, ALDOA, STK32B and FAM190A are related to marbling. For reproduction traits, CCNB2 and SLC8A3 affect oocyte development. We also found two well-known genes, GHR (which affects meat production and quality and EDAR (associated with hair thickness were associated with German mutton merino sheep. Furthermore, four genes (POL, RPL7, MSL1 and SHISA9 were associated with pre-weaning gain in our previous genome-wide association study.Our results indicated that combine locus-specific branch lengths and di statistical approaches can reduce the searching ranges for specific selection. And we got many credible candidate genes which not only confirm the results of previous reports, but also provide a suite of novel candidate genes in defined breeds to guide hybridization breeding.

    Full Text Available A study was conducted in order to evaluate the contamination by Brucella spp. of meat from animals slaughtered because they had resulted positive for brucellosis at some time during their life. After slaughter and before delivery to market outlets, swab samples were taken from 307 carcasses of infected animals: 40 cattle, 60 sheep and 207 goats. The swabs were subsequently analysed by means of polymerase chain reaction (PCR tests. In addition, bacteriological tests were carried out on the lymph nodes and internal organs of the same animals. Brucella spp. was detected by means of PCR in 25/307 carcasses (8%: 1 bovine (2.5%, 9 sheep (15% and 15 goats (7.2% and was isolated by means of a cultural method in 136/307 carcasses (44%. Moreover, additional analysis, performed on lymph nodes from the same carcasses that had proved positive by PCR, allowed highlighting type 3 Brucella abortus in the bovine carcass and type 3 Brucella melitensis in the sheep and goat carcasses. The study shows that cattle, sheep and goats meat of animals slaughtered because they had tested positive for brucellosis may be contaminated by Brucella spp. As this could constitute a real risk of transmission to both butchery personnel and consumers, the meat of animals infected by Brucella spp. should be analysed before being marketed. In this respect, PCR technique performed on swabs proved to be more useful, practical and faster than the traditional bacteriological method.

    Sheep hips have a natural non-spherical femoral head similar to a cam-type deformity in human beings. By performing an intertrochanteric varus osteotomy, cam-type femoro-acetabular impingement (FAI) during flexion can be created. We tested the hypotheses that macroscopic lesions of the articular cartilage and an increased Mankin score (MS) can be reproduced by an experimentally induced cam-type FAI in this ovine in vivo model. Furthermore, we hypothesized that the MS increases with longer ambulatory periods. Sixteen sheep underwent unilateral intertrochanteric varus osteotomy of the hip with the non-operated hip as a control. Four sheep were sacrificed after 14, 22, 30, and 38-weeks postoperatively. We evaluated macroscopic chondrolabral alterations, and recorded the MS, based on histochemical staining, for each ambulatory period. A significantly higher prevalence of macroscopic chondrolabral lesions was found in the impingement zone of the operated hips. The MS was significantly higher in the acetabular/femoral cartilage of the operated hips. Furthermore, these scores increased as the length of the ambulatory period increased. Cam-type FAI can be induced in an ovine in vivo model. Localized chondrolabral degeneration of the hip, similar to that seen in humans (Tannast et al., Clin Orthop Relat Res 2008; 466: 273-280; Beck et al., J Bone Joint Surg Br 2005; 87: 1012-1018), can be reproduced. This experimental sheep model can be used to study cam-type FAI. Copyright © 2012 Orthopaedic Research Society.

    Full Text Available AbstractThis survey was carried out to determine the infection rate of Coenurus cerebralis in Urmiaabattoir, West Azerbaijan, Iran. A total of 402 sheep heads were examined and the number ofC. cerebralis cysts per each head was recorded. Thirty three sheep heads were examined eachmonth during 12 months from 2006 to 2007. Of 402 heads, a number of 75 heads (18.65%were infected with C. cerebralis. The cysts located in the left and right hemispheres andcerebellum were 54.63%, 40.20% and 5.15%, respectively. The infected heads contained 1-4cysts. The highest and lowest prevalence were detected in sheep in March (42.42% and in July(2.94%, respectively. The infection rates according to age of sheep were 42.02% in 0.5 to 2years, 22.50% in 2 to 4 years and 8.92% in older than 4 years. The age specific infection ratesamong age groups were significantly differed (P 0.05.
