Fifty-nine female yearlings of local Awassi sheep were randomly divided into 2 groups. Animals in group T (treated) were fitted with intravaginal sponges containing 60 mg of medroxyprogesterone acetate for 14 days followed by 400 IU of pregnant mare's serum gonadotrophin (PMSG) at sponge withdrawal, whereas group C (control) received no treatment. Oestrus rate was 92.7% and 11.2% for groups T and C, respectively. Lambing rate was 78% and 5.6% for groups T and C, respectively. Twinning rate was 31.3% in group T compared to zero in group C. Average birth weight for single born lams (4.7 ± 0.6 kg) was significantly (P > 0.05) higher than twin born lams (3.0 ± 0.5 kg) in group T. The average concentration of blood progesterone collected between days 17-19 after mating was 19.30 nmol/1 and the accuracy of early pregnancy diagnosis was 100%. It was concluded that, it is possible to induce synchronized oestrus, and to increase the twinning rate in Syrian Awassi sheep yearlings outside the breeding season, using intravaginal sponges and PMSG. In addition, early pregnancy diagnosis could be successfully determined in female Awassi sheep yearlings between days 17-19 after-mating. (author)

Full Text Available Two experiments were conducted to evaluate the effect of replacing soybean meal with xylose-treated soybean meal (soypass meal; SPM on performance of nursing Awassi ewes and fattening lambs. In Experiment 1, lasting for eight weeks, 39 Awassi ewes and their lambs were randomly assigned to three diets. Diets were formulated by replacing soybean meal from the basal diet (CON-SBM; n=13 with 50% (50% SPM; n=13 and 100% (100% SPM; n=13 SPM. Initial and final weights of the ewes were not different (P>0.55 among diets. Total gain and average daily gain (ADG of lambs were similar (P=0.44 among diets. Ewes fed the CON-SBM diet tended (P0.38 in milk component percentages among diets were observed. In Experiment 2, lasting for 63 days, twenty weaned lambs were used to determine the effects of replacing soybean meal with SPM on growth performance. Diets were either soybean meal (SBM; n=10 or SPM (SPM; n=10. Nutrient intake and digestibility were not different between diets. However, rumen undegradable protein intake was greater (P0.05 between the diets. Results suggest that replacement of soybean meal with soypass meal is not likely to produce any production benefits in nursing Awassi ewes and fattening lambs except for the slight improvement of milk yield.

Full Text Available We investigated the reproductive responses of Awassi ewes under Cornell alternate month accelerated lambing (CAMAL system. Ewes were randomly allocated to two experimental groups. The first group (control group consists of 20 ewes exposed to rams in September under conventional management system while the second group (CAMAL were divided into four sub-flocks contain 20 head of ewes each one were exposed to rams to obtain three lambing in two years with different breeding and lambing months. In CAMAL ewes, oestrus was synchronized using intra-vaginal sponges with progesterone and PMSG administration. Results revealed that within CAMAL group, the percentage of animals in heat, onset of oestrus, litter size, birth weight and weaning weight were affected by mating months. September and November were the most appropriate months for oestrus ratio (97.5 % and litter size (1.18 and 0.98, respectively. Lambs of control group were heavier at birth and weaning than those of CAMAL group. On the other hand lamb yield was not affected statistically by the CAMAL administration.

An experiment on Syrian Awassi ewes and yearlings was conducted out-side the normal breeding season to study the possibility of inducing oestrus and increasing birth rate as an attempt to improve the reproductive efficiency, in addition to evaluating the possibility of early pregnancy diagnosis using progesterone radioimmunoassay kits. One-hundred-and fifty-five local female awassi sheep (96 ewes and 59 ewe lambs) were divided into 4 groups. Group T1 (n= 50 ewes) were fitted with itravaginal sponges containing 60 mg of medroxy progesterone acetate (MAP) for 14 days followd by 600 IU of pregnant mare's serum gonadotrophin (PMSG) at sponge withdrawal, whereas the control group C1 (n= 46 ewes) received no treatment. Group T2 (n= 41 yearlings) were fitted with itravaginal sponges containing 60 mg of MAP for 14 days followed by 400 IU PMSG at sponge withdrawal, whereas the control group C2 (n= 18 yearlings) received no treatment. The females in both T1 and T2 groups responded to the hormonal treatment, and showed oestrus behaviour within 36-48 h of sponge withdrawal. Total oestrus rate was 96% and 92.7% for groups T1 and T2, respectively. Lambing rates were 80%, 32.6%, 78.0% and 5.6% for groups T1, C1, T2 and C2, respectively. Twinning rates increased to 32.5% and 33.3% for groups T1 and T2, respectively, compared to 6.7% and 0% for groups C1 and C2, respectively. There were no significant differences in pregnancy duration between groups T1 (151.7 ± 1.7 days), and T2 (154.4 ± 1.5 days), and between single (154.4 ± 1.8 daus and 151.5 ± 1.6 days) and twin-born lambs (151.7 ± 1.5 days and 150.8 ± 1.3 days) for single and twin born lambs in groups T1 and T2, respectively. Hormonal treatment had no effect on the overall average lamb birth weight, which was 4.3 ± 1.0 Kg, 4.4 ± 0.7 Kg and 3.9 ± 1.0 Kg for groups T1, C1, and T2, respectively, and the birth weight for the only lamb born in group C2 was 4.0 kg. However, average birth weight for single born lambs was

A prospective cohort study was conducted using 32 randomly selected Awassi sheep flocks to identify factors hypothesized to be associated with the occurrence of pregnancy, twinning and fetal loss between August 2005 and May 2006 in the region of Al-Safawi (northeast of Jordan). Vitamins A and E and selenium concentrations were determined on 448 blood samples. Using the forward selection procedure of the logistic regression module, models with statistically significant risk factors (P loss. Serum vitamin A concentration levels were associated with pregnancy (OR = 2.26, 2.48), twinning (OR = 6.49, 17.74) and fetal loss (OR = 0.13, 0.19). Primiparous ewes were 48% less likely to become pregnant than fourth or higher parity ewes. The likelihood of twinning increased significantly in ewes up to the third parity. Ewes that were fed 700-900 g barley, 250-300 g wheat-bran per head per day and grazed on vegetables residues were 4.15 times more likely to have twins than ewes that were fed 600 g barley and 200 g wheat-bran per head per day. Fetal loss in first and second parity ewes was about 3 times more likely than that in third or higher-parity ewes. Ewes pregnant with twins were about 14 times more likely to have fetal loss than ewes carrying single fetus. Pregnant ewes of the stationary flocks were 37% less likely to have fetal loss than ewes of the semi-nomadic flocks. These results demonstrate that stationary Awassi sheep flocks had higher pregnancy and twinning rates and less pregnancy loss. Supplementation of vitamin A, providing sufficient quantity of dry feed and increasing ram: ewe ratio for primiparous ewes of semi-nomadic flocks is essential to improve Awassi sheep reproductive performance.

2007-01-01

Nutritional value of Kallar grass (Leptochloa fusca Linn) hay (whole plant), a salt-tolerant plant, was estimated by determinning its composition (ash, crude protein CP, crude fibre CF, ether extract EE, neutral-detergent fiber NDF, acid-detergent fiber ADF, acid-detergent lignin ADL); and the in vitro organic matter digestibility (IVOMD), metabolizable energy (ME), net energy of lactation (NEL) and gross energy (GE). Moreover, dry matter, energy and protein yields per hectar were also estimated. The effects of feeding Kallar grass hay to pregnant Awassi ewes on reproductive performance, serum progesterone changes using radioimmunoassay, and on birth and weaning weights of lambs born were also determined. Experimental ewes received daily 300 g of Kallar grass hay in addition to lentil straw and concentrates to cover their nutritional requirements. The results indicated that the nutritive components of Kallar grass were (g kg -1 dry matter): ash 96, CP 93, CF 290, EE 21, NDF 755, ADF 416 and ADL 94. IVOMD was 49.3%, and energy values (MJ kg -1 dry matter) were: GE 26.88, ME 6.41 and NEL 3.02. Dry matter and crude protein yields of Kallar grass hay were 7875 and 732 kg ha -1 , respectively, and the energy produced (MJ ha -1 ) was: GE 211680, ME 50479 and NEL 23783. Kallar grass had no effects on the reproductive performance of pregnant Awassi ewes duration, of pregnancy (150.1 ± 2.2 days), progesterone patterns, birth (4.7±1.0 kg) or on weaning weights (22.7 ± ≤ 5.5 kg) of lambs.

2004-01-01

Results showed that testosterone exists in the blood of ram lams as early as the first month of age with no significant difference between single and twin births. This level, however, increased gradually with advancing age of ram lambs, indicating that the gonads (testes) of these growing lambs were active in secreting testosterone hormone after birth, but the rate of secretion differed with age of the lambs. A sharp increase in testosterone level was recorded at age of 8 months in twin births (5.32 ± 20.99 nmol/l) and in single births (7.26 ± 3.29 nmol/l). Throughout the study period, mean testosterone serum level was 3.29 ± 2.73 and 2.54 ± 2.15 nmol/l for single and twin births, respectively, as compared with an overall mean of 3.00 ± 2.49 nmol/l. However, the monthly difference in testosterone level between single and twin births was not significant (P>0.05) throughout the study period (10 months). Results also indicated an increase in live weight of lambs with advancing age, and live weight in single births was higher, but not significantly, than in twin births throughout the study period. Results of the study showed a sharp increase in the mean live weight of single births at age of 8 months (48.5 ± 10.8 kg) as compared with an overall live weight of the lambs (35.8 ± 15.2 and 32.7 ± 15.4 kg for single and twin births, respectively). A positive and significant correlation (r= 0.95, P>0.0001) was found between serum testosterone level and lamb live weight during the first 10 months of their age. Finally and for the first time, normal serum testosterone levels in Syrian Awassi ram lambs were determined during early stages. It was concluded, based on both, testosterone level and lamb live weight, that puberty in Awassi ram lambs could be reached at 8 months of age with a mean live weight of around 47 kg. Type of birth, lamb birth weight or weaning weight had no significant effect on testosterone level. (author)

Fifty-three transitional-anestrus Awassi ewes, randomly assigned to three groups: fluorogestone acetate (FGA, n = 18), FGA-Prostaglandin (FGA-PGF, n = 18) and control (n = 17), were used to examine the effect of estrus synchronization protocols and steroid hormones concentrations on milk somatic cell count (SCC). Intravaginal FGA sponge was inserted for 13 days and 600 IU equine chorionic gonadotropin was administered for ewes of FGA and FGA-PGF groups at the time of sponge removal (day 0). In addition, 10 mg was administered to ewes of FGA-PGF group on day 0. Blood and milk samples were collected from all ewes on days -13, -6, 0, 1, 2, 7 and 14. Estradiol had significant positive correlation with the SCC during the periods of sponge insertion (P = 0.015, r = 0.235) and within two days (P = 0.063 r = 0.23) after sponge removal with no correlation with SCC of both udder halves during the luteal phase. Progesterone concentrations, on the other hand, had a significant positive correlation (P progesterone on days 7 and 14 to pre-synchronization values. In conclusion, sheep milk SCC is affected significantly with induction of estrus and steroid hormones concentrations. However, peak SCC recorded during estrus was far below the upper limit of the current standard for normal milk. With the current standards for SCC of 1,000,000/ml as legal limit for abnormal milk control programs in sheep, estrus synchronization programs and the estrus status should not be considered when bulk-tank milk SCC is being investigated, but should be considered during the process of setting new standards.

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.

The aim of this study was to evaluate an experimental Salmonella Enteritidis (SE) bacterin and an indirect ELISA system to assess quantitatively the acquired immunity in Awassi ewes to the vaccine and/or Echinacea purpurea (EP) dried roots. Four treatments of the ewes were included in the experimental design, with 6 ewes/treatment. The first treatment (T1) had the controls that were non-vaccinated and non-treated with EP. The T2 ewes were only treated with EP. The T3 and T4 ewes were vaccinated at D1 (initiation of trial) and D10, while the T4 ewes were additionally administered the EP dried roots. Blood was collected from the jugular vein of all ewes at D1, D10, D21 and D45. The construction of the vaccine and the ELISA are detailed within the manuscript. The ELISA was able to detect quantitatively the significant acquired primary and secondary immunity to the vaccine in T3 and T4 ewes, compared to their low level of background immunities at initiation of the experiment (p0.05) in T1 control ewes, and in the T2 ewes that were given only the (EP) (p>0.05). Moreover, the ELISA was able to uncover the significant seroconversion of secondary immune response in T4 ewes at D21 compared to that at D10 (pewes. This is the first work in literature that reports the need to supplement the vaccination by the experimental SE bacterin with daily oral intake of 250mg of EP-dried roots, effective the first vaccination day and up to 21 days, for obtaining a statistically significant seroconversion.

Fifty-six Awassi ram lambs, aged between 5.0-5.5 months, represented two types of birth (single and twin) and two production lines (milk and meat) were used. Blood samples were taken from the jugular vein once a week for a period of 2 months and then twice a month for the following 10 months. Plasma was prepared and stored frozen at -20 deg. C until analysed for testosterone using radioimmunoassay (RIA). The effect of weight and age of lambs, type of birth and production line on testosterone level were studied. Results showed that there was only a significant effect (P -1 . This level was higher in the lambs of the milk than those of meat line (5.6 ± 0.7 vs. 3.9 ± 0.7 nmol l -1 ), and in the single than in twin births (5.8 ± 0.9 vs. 4.2 ± 0.6 nmol l -1 ), and the first peak occurred at 9 months of age. It was concluded that the level of testosterone in Awassi ram lambs increased with age. It was also concluded that the attainment of puberty in Awassi ram lambs based on the level of testosterone in the blood was at the age of 9 months. (authors)

The aim of this study was to investigate the effects of using a commercially-available polyvalent mastitis vaccine on the bacteriological cure rate of existing subclinical mastitis in Awassi sheep. A total of 164 lactating ewes were divided into two main groups according to udder health and milk somatic cell count (SCC): Group 1=normal (N; n=80) and Group 2=subclinical mastitis (SC; n=84). Each group was then subdivided randomly into two treatment groups: N vaccinated (N vax ; n=38), N non-vaccinated (N nvax ; n=42), SC vaccinated (SC vax ; n=42), and SC non-vaccinated (SC nvax ; n=42). The vaccine was administered as per manufacturer's recommendations. Milk samples were collected aseptically from all ewes before vaccine administration (T0) and again on days 28 (T2) and 42 (T3) of the experiment. In the SC group, the bacteriological cure rates in vaccinated and non-vaccinated ewes were 76% and 69%, respectively. In N group, the new intramammary infection rates in vaccinated and non-vaccinated ewes were 48% and 50%, respectively. Vaccination of normal ewes resulted in a significant (pewes on days 28 and 42 was 19% and 20%, respectively. The prevalence of new intramammary infection rate in N nvax group on days 28 and 42 was 33% and 30%, respectively. In SC vax group, the bacterial growth rate on days 28 and 42 was 44% and 35%, respectively. In SC nvax group, the bacterial growth rate on days 28 and 42 was 27% and 32%, respectively. There was no statistically significant effect of vaccination on any of the studied milk composition parameters. This is a preliminary study that indicated a possible protective effect of vaccination against mastitis in sheep. Further, case-controlled studies are indicated to estimate the level of immunity this vaccine provides to vaccinated sheep.

The aims of this study were to evaluate the effects of intramammary infusion of sage ( Salvia officinalis ) essential oil (EO) on milk somatic cell count (SCC), milk composition parameters and selected hematology and serum biochemical parameters in 20 Awassi ewes affected with subclinical mastitis. The dried leaves of sage were used to extract the EO by hydrodistillation. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of sage EO against Staphylococcus aureus were determined by the broth dilution method. Ewes were divided randomly into three main groups and received one of the following treatments; Group 1 (n=5): Dimethyl sulfoxide (DMSO) alone (5 ml; 0.2 ml of DMSO in 4.8 ml of saline), Group 2 (n=5): Amoxicillin alone (3 ml), and Group 3 (n=10): Sage EO (5 ml of sage EO solution [0.2 ml DMSO+1 ml EO+3.8 ml sterile saline]). All treatments were administered by intramammary infusion into each teat twice per day for 3 consecutive days. Milk samples for SCC and milk components determination and whole blood samples for hematology and serum biochemical analyses were collected before treatment (T0) and at 24 (T24) and 48 (T48) h after the last treatment. The MIC and MBC of sage EO against S. aureus were 12.5% and 6.1%, respectively. SCC was decreased significantly (psage EO and amoxicillin treated groups. Milk fat and lactose were increased significantly (psage EO and amoxicillin treated ewes while no significant changes were observed in the percentages of solids-not-fat, protein and total solids. No significant effects of sage EO treatment on any of the hematology or serum biochemical parameters were observed. There were no local or systemic side effects observed in any of the treated ewes. However, further clinical trials are warranted to determine safety and possible withdrawal times in milk before its recommendation for use in organic operations.

The Syrian crisis is considered the 'world's single largest crisis for almost a quarter of a century that has the biggest refugee population from a single conflict in a generation' (UN High Commissioner for Refugees, 2016). The rapid adoption of Facebook among Syrians questions whether it helps in maintaining the social capital of a war-torn nation and a dispersed Syrian population worldwide. Data was collected by means of a Facebook survey from 964 Syrian users. Results indicated that Facebook enhanced social identity and social capital through facilitating communication, collaboration and resource sharing among dispersed Syrians inside and outside the country. However, the offline rift of the nation was extended to Facebook through promoting hate speech among opposed parties. Results of this study may advance the understanding of the role of Facebook on social capital in countries going through similar crisis situations.

The Awassi fat-tail sheep is desired in the Middle East and Sahara for its hardiness and resistance. In this region, the adaptability of Awassi rams to elevated heat stress is controversial. The objective of this study was to assess the effect of ambient or testicular 43 deg C heat on semen characteristics. 12 Awassi rams of 1.2 to 2 years were allowed an initial adaptation period (P0), followed by two experimental phases (P1 and P2), each including a period of heat stress (HS1 and HS2) followed by a period of recovery from heat stress (R1and R2). Heat stress conditions were considered when ambient temperature (Group 2) or testicular environment (Group 3) reached 42 to 44 deg C. Control animals (Group 1) were exposed to ambient environmental conditions. Temperature-humidity index (THI) as a relationship of ambient temperature, wet and dry humidity effect along with respiration and pulse rate, body temperature and live body weight (BW) were measured weekly as adaptation parameters. Reproductive parameters assessed included scrotum circumference and testicular volume measured twice per heat stress period, whereas semen volume density,concentration and motility were measured twice weekly. Data were analyzed using the mixed procedure of SAS under a time series analysis model, with treatment and time nested within period as main effects, and treatment by time within period as interaction terms. Treatment means were separated using Fisher protected LSD. Results showed a THI of 25.7 during therest periods (R1 and R2), 30 during HS1 and 28 during HS2. BW decreased with ambient stress, whereas respiration rate increased during heat stress periods (HS1 and HS2).

Full Text Available The purpose of this study was to increase fertility in sheep by applying modern biotechnology: induction and synchronization of estrous in non- breeding season. The ewes were divided into 3 equal batches. In all batches intravaginal sponge (Veramix/Intervet containing 60 mg of MPA was left in the vagina for 14 days. Immediately after removal of the sponge an injections of prostaglandin (Dinolytic/Pfizer at the dose of 12.5 mg (2,5ml/animal was administered in batch II. Batch III received two injections: PMSG hormone (Folligon/Intervet at the dose of 500 IU/animal and prostaglandin (Dinolytic/Pfizer at the dose of 12.5 mg (2,5 ml/animal. The research focused on several directions: assessment of estrous manifestation; occurrence of estrous interval after completion of hormonal therapy; duration of estrous; appreciation of gestation after the first and second estrous clinically manifested; percentage of fecundity. From the results obtained it follows that induction and synchronization of estrous in non-breeding season showed economic advantages by shortening the time needed for the installation of gestation, the possibility of lambing distribution, preparation and organization of mating.

Determine the impact of the Syrian crisis on the hospitalization of Syrians in a psychiatric setting. All Syrians admitted to a psychiatric hospital in Lebanon between the 1st of January 2009 and the 31st of December 2013 were included. Number of admissions, psychiatric disorders and demographic and clinical data relative to patients were compared between those admitted before and after the crisis. 44 patients were admitted before the crisis and 106 after it. The distribution of diagnosis varied significantly after the crisis (p = 0.056) with the majority of patients being admitted for schizophrenia (37.7 %). The prevalence of suicidal ideation was higher after the crisis (p = 0.03) but suicidal attempts, need for electroconvulsive therapy and length of hospitalization did not differ significantly between both groups. Clinicians should be aware of the possible burden of mental illness in Syrians after the beginning of the Syrian crisis.

This study aimed to estimate evolutionary distances and to reconstruct phylogeny trees between different Awassi sheep populations. Thirty-two sheep individuals from three different geographical areas of Jordan and the Kingdom of Saudi Arabia (KSA) were randomly sampled. DNA was extracted from the tissue samples and sequenced using the T7 promoter universal primer. Different phylogenetic trees were reconstructed from 0.64-kb DNA sequences using the MEGA software with the best general time reverse distance model. Three methods of distance estimation were then used. The maximum composite likelihood test was considered for reconstructing maximum likelihood, neighbor-joining and UPGMA trees. The maximum likelihood tree indicated three major clusters separated by cytosine (C) and thymine (T). The greatest distance was shown between the South sheep and North sheep. On the other hand, the KSA sheep as an outgroup showed shorter evolutionary distance to the North sheep population than to the others. The neighbor-joining and UPGMA trees showed quite reliable clusters of evolutionary differentiation of Jordan sheep populations from the Saudi population. The overall results support geographical information and ecological types of the sheep populations studied. Summing up, the resulting phylogeny trees may contribute to the limited information about the genetic relatedness and phylogeny of Awassi sheep in nearby Arab countries.

Full Text Available Synchronization of oestrus has been used to increase reproductive efficiency in most animals, including ewes. The aim of the present study was to compare the effect of the length of a progestagen treatment (12 d vs. 6 d on synchronization efficiency (oestrus response, time to onset of oestrus and duration of oestrus and fertility rate using fluorogestone acetate (FGA progestagen sponge treatment with pregnant mare serum gonadotropin (PMSG administration applied at different times of sponge removal. Ewes (n = 68 were divided into two groups; long term (LT, n = 33 and short term (ST, n = 35 groups treated with FGA progestagen sponges. At the end of intravaginal sponge treatment period the animals of each group were divided into the 3 subgroups in relation to time of PMSG (300 IU treatment. PMSG treatment was applied 24 h before sponge removal, at sponge removal and 24 h after sponge removal for LT1 and ST1, LT2 and ST2, and LT3 and ST3, respectively. Each ewe was inseminated intra-cervically twice with skim cow milk-diluted semen (1000 × 106 motile cells/ml 40 h and 60 h after sponge removal. Non-return rates (NRR-30 were monitored from 12 day after sponge removal to 30 day with the aid of teaser rams. Onsets of oestrus response and oestrus cessation were significantly different (P P P >.

Background Lebanon, a small Middle Eastern country facing constant political and national unity challenges with a population of approximately 300,000 Palestinian and Iraqi refugees, has welcomed more than 1.2 million Office of the United Nations Commissioner for Refugees (UNHCR)-registered Syrian refugees since 2012. The Government of Lebanon considers individuals who crossed Lebanese–Syrian borders since 2011 as “displaced”, emphasizing its long-standing position that Lebanon is not a state for refugees, refusing to establish camps, and adopting a policy paper to reduce their numbers in October 2014. Humanitarian response to the Syrian influx to Lebanon has been constantly assembling with the UNHCR as the main acting body and the Lebanon Crisis Response Plan as the latest plan for 2016. Methods Review of secondary data from gray literature and reports focusing on the influx of Syrian refugees to Lebanon by visiting databases covering humanitarian response in complex emergencies. Limitations include obtaining majority of the data from gray literature and changing statistics due to the instability of the situation. Results The influx of Syrian refugees to Lebanon, an already weak and vulnerable state, has negatively impacted life in Lebanon on different levels including increasing demographics, regressing economy, exhausting social services, complicating politics, and decreasing security as well as worsened the life of displaced Syrians themselves. Conclusion Displaced Syrians and Lebanese people share aggravating hardships of a mutual and precarious crisis resulting from the Syrian influx to Lebanon. Although a lot of response has been initiated, both populations still lack much of their basic needs due to lack of funding and nonsustainable program initiatives.

Full Text Available This article touches upon geopolitical dimension of the Syrian conflict. The authors consider in details regional subdivision of Syria and relations of Syrian regions with border countries. The authors of the article conclude that Arab nationalism as the Syrian state ideology and positioning of Syria as the center of Arab world were indispensable taking into account multiconfessional nature of Syria. Authors study the geostrategical doctrine of Hafez Asad (1970-2000 aimed to restore the territorial integrity of Syria (return of the Golan heights and creation of Great Syria, bring to light reasons of the alliances of Syria with Soviet Union and Iran. The authors discover reasons of hostility toward Syria from such actors as United States, Saudi Arabia, Turkey. The hostile attitude of the US political elites toward the Syrian state can be explained by American intention to undermine strategic partnership between Syria and Iran. Enmity of Saudi hostility toward the Syrian regime began with the assassination of the Lebanese Prime Minister Rafic Hariri (2005. This action destroyed the political balance in Lebanon and was considered by the Saudis as a threat to their interests. Article contains analysis of the Syrian role in the Saudi-Iranian rivalry. To opinion of the authors, Turkish involvement in the Syrian conflict began with the attempts of the regime’s change in this country and evolved to the defense of Turkish national interests from the Kurdish factor. The authors make some conclusions about the role of US, Iran, Saudi Arabia, Turkey in the Syrian conflicts. In the article it’s made some forecasts about the development of Syrian conflict. The authors especially predict possibility of disintegration of the Syrian state according to spheres of influence of the external actors involved to this conflict with Mediterranean coast, Homs and Damascus under the control of government, northern regions of the country under Kurdish control, Raqqa

Full Text Available While the Syrian refugees crisis has increasingly continued its effect in both Turkey and other neighboring countries and European countries for more than five years, refugees do not adapt themselves to society in country of asylum, and are exposed to social exclusion. The purpose of the study is to explore social representations of social media users toward Syrian refugees in Turkey with a qualitative approach; because social representations may indicate the problems in the integration process of Syrian refugees and Turkish society, and the reasons of social exclusion toward Syrian refugees. Accordingly 98 entries, which were taken from frequently used social dictionaries in Turkey, were evaluated by researchers and seven thematic units were formed. Thematic units reflect (i perceived negative features of Syrian refugees, (ii perceived threats in Turkey due to Syrian refugees, (iii criticisms toward Syrian refugees policy of Turkish government, (iv positive attitudes toward Syrian refugees, (v perceived political importance of Syrian refugees, (vi proposed solutions toward perceived Syrian refugees problem, and (vii other criticisms toward Syrian refugees issue. Findings provide useful information which can be used to enable the social adaptation of Syrian refugees into Turkish society

Imaging Ewing's sarcoma

1998-01-01

Ewing's sarcoma is a highly malignant neoplasm of the bone whose origin is still uncertain. A strong relationship exists between Ewing's sarcoma and tumors of neural origin (Ewing family of tumors). Ewing's sarcoma must be distinguished from other round-cell tumors like lymphoma and neuroblastoma and also must be differentiated from osteogenic sarcomas. On plain radiographs, Ewing's sarcoma appears as a lytic or mixed lytic-sclerotic, rarely as predominantly sclerotic lesion with margins Lodwick grade III. It is located primarily in the diaphyseal and metadiaphyseal regions of the long bones of the lower extremities. A large soft tissue tumor is usually present. Magnetic resonance imaging is the imaging modality of choice to evaluate the extent of the primary lesion, to monitor the response to neoadjuvant chemotherapy and to follow up non-resected Ewing's sarcomas. Bone scintigraphy is necessary to detect skeletal metastasis, and 201 thallium scanning has been shown to be sensitive in the monitoring of treatment response. Today, computed tomography is not longer used to image the tumor site; however, spiral CT of the lungs plays a central role as a staging and follow-up tool. (orig.) [de

Calm Merino ewes have a higher ovulation rate and more multiple pregnancies than nervous ewes.

2017-07-01

In 1990, two selection lines of Merino sheep were established for low and high behavioural reactivity (calm and nervous temperament) at the University of Western Australia. Breeding records consistently showed that calm ewes weaned 10% to 19% more lambs than the nervous ewes. We hypothesise that calm ewes could have a higher ovulation rate than nervous ewes and/or calm ewes could have a lower rate of embryo mortality than nervous ewes. We tested these hypotheses by comparing the ovulation rate and the rate of embryo mortality between the calm and nervous lines before and after synchronisation and artificial insemination. Merino ewes from the temperament selection lines (calm, n=100; nervous, n=100) were synchronised (early breeding season) for artificial insemination (day 0) (intravaginal sponges containing fluogestone acetate and eCG immediately after sponge withdrawal). On day-17 and 11 ovarian cyclicity and corpora lutea, and on days 30 and 74 pregnancies and embryos/foetuses were determined by ultrasound. Progesterone, insulin and leptin concentrations were determined in blood plasma samples from days 5, 12 and 17. Ovarian cyclicity before and after oestrus synchronisation did not differ between the lines, but ovulation rate did (day-17: calm 1.63; nervous 1.26; Pewes was higher than on day-17. Loss of embryos by day 30 was high (calm: 71/150; nervous: 68/130); but nervous ewes had a lower proportion (15/47) of multiple pregnancies compared with calm ewes (30/46; Pewes had higher insulin (32.0 pmol/l±1.17 SEM; P=0.013) and lower leptin (1.18 μg/l±0.04 SEM; P=0.002) concentrations than calm ewes (insulin: 27.8 pmol/l±1.17 SEM; leptin: 1.35 μg/l±0.04 SEM). The differences in reproductive outcomes between the calm and nervous ewes were mainly due to a higher ovulation rate in calm ewes. We suggest that reproduction in nervous ewes is compromised by factors leading up to ovulation and conception, or the uterine environment during early pregnancy, that reflect

The objectives of this study were 1) to compare the effects of a ME () or a NE () system for rationing ewes during late gestation on ewe and progeny performance and 2) to investigate incremental increases in NE allocation above 100% of recommendation during late gestation on ewe and progeny performance. Fifty-two twin-bearing ewes ( = 13 per treatment) were rationed to either 100% of recommended ME requirements (100% ME) or 100, 110, or 120% of recommended NE requirements (100% NE, 110% NE, and 120% NE) from d 112 of gestation to parturition. Mean energy intake, measured as ME and NE, from Day 112 of gestation to parturition was higher in all NE treatments compared with 100% ME ewes ( = 0.01). Ewes offered the 3 NE treatments had a higher live weight at parturition compared with 100% ME ewes ( = 0.02), with 100% NE and 120% NE ewes still being heavier than 100% ME ewes at 35 d postpartum ( = 0.02). Increasing NE allowance resulted in a linear decrease in the level of BCS loss prepartum ( = 0.01) and a linear increase in the level of BCS loss postpartum ( = 0.01). There was no difference observed between any of the treatments in total colostrum produced to 18 h postpartum ( = 0.29) or in total colostrum intake to 18 h postpartum ( = 0.27). Increasing maternal NE allowance led to a linear increase in lamb serum IgG concentration at 24 h postpartum ( = 0.03). The estimated milk production of 120% NE ewes tended to be higher than all other treatments at wk 6 of lactation ( = 0.08). Colostral SFA levels from 100% ME ewes was lower than that of all 3 NE treatments ( = 0.01), and unsaturated fatty acid (UFA) levels in colostrum of the 100% ME ewes were lower than those of the 100% NE ewes ( = 0.01). Cumulative levels of milk SFA, UFA, and MUFA did not differ between treatments ( = 0.19). Lamb growth rates during the first 5 wk postpartum were unaffected by treatment ( = 0.18) as were days to slaughter ( = 0.34). It can be concluded that both ME and NE systems used in this

2017-08-01

Although Arabian horses have been bred in strains for centuries and pedigrees have been recorded in studbooks, to date, little is known about the genetic diversity within and between these strains. In this study, we tested if the three main strains of Syrian Arabian horses descend from three founders as suggested by the studbook. We examined 48 horses representing Saglawi (n = 18), Kahlawi (n = 16) and Hamdani (n = 14) strains using the Equine SNP70K BeadChip. For comparison, an additional 24 Arabian horses from the USA and three Przewalski's horses as an out group were added. Observed heterozygosis (H o ) ranged between 0.30 and 0.32, expected heterozygosity (H e ) between 0.30 and 0.31 and inbreeding coefficients (F is ) between -0.02 and -0.05, indicating high genetic diversity within Syrian strains. Likewise, the genetic differentiation between the three Syrian strains was very low (F st  horses. Among Arabian horses, we found three clusters containing either horses from the USA or horses from Syria or horses from Syria and the USA together. Individuals from the same Syrian Arabian horse strain were spread across different sub-clusters. When analyzing Syrian Arabian horses alone, the best population differentiation was found with three distinct clusters. In contrast to expectations from the studbook, these clusters did not coincide with strain affiliation. Although this finding supports the hypothesis of three founders, the genetic information is not consistent with the currently used strain designation system. The information can be used to reconsider the current breeding practice. Beyond that, Syrian Arabian horses are an important reservoir for genetic diversity. © 2017 Stichting International Foundation for Animal Genetics.

Full Text Available The remaining small Jewish communities of Syria run the risk of disappearing completely due to the marginalization suffered as a consequence of the political situation since 1948. The Eli Cohen affair (1965, the Six-­Day War (1967, and the Yom Kippur War (1973 made the Baathist authorities of the country consider definitively the Syrian Jews as suspected Zionists or Zionist sympathizers. Nevertheless, in Syrian popular perceptions, the view of the Jews and Judaism did not always coincide with the ideology and propaganda emanating from the regime. In fact it is very interesting to note how good memories of times past, about an erstwhile coexistence with members of the Jewish community, still survive among many Syrians, both Muslims and Christians, belonging to the so-­called “urban middle class.” This paper evaluates some examples, in the forms of anecdotes, popular sayings and proverbs, dealing with the Jews, and popularized in Syrian colloquialisms, in order to reveal some of the popular views of Judaism and Jews within Syrian society.

Promiscuous partnerships in Ewing's sarcoma.

Science.gov (United States)

Sankar, Savita; Lessnick, Stephen L

2011-07-01

Ewing's sarcoma is a highly aggressive bone and soft tissue tumor of children and young adults. At the molecular genetic level Ewing's sarcoma is characterized by a balanced reciprocal translocation, t(11;22)(q24;q12), which encodes an oncogenic fusion protein and transcription factor EWS/FLI. This tumor-specific chimeric fusion retains the amino terminus of EWS, a member of the TET (TLS/EWS/TAF15) family of RNA-binding proteins, and the carboxy terminus of FLI, a member of the ETS family of transcription factors. In addition to EWS/FLI, variant translocation fusions belonging to the TET/ETS family have been identified in Ewing's sarcoma. These studies solidified the importance of TET/ETS fusions in the pathogenesis of Ewing's sarcoma and have since been used as diagnostic markers for the disease. EWS fusions with non-ETS transcription factor family members have been described in sarcomas that are clearly distinct from Ewing's sarcoma. However, in recent years there have been reports of rare fusions in "Ewing's-like tumors" that harbor the amino-terminus of EWS fused to the carboxy-terminal DNA or chromatin-interacting domains contributed by non-ETS proteins. This review aims to summarize the growing list of fusion oncogenes that characterize Ewing's sarcoma and Ewing's-like tumors and highlights important questions that need to be answered to further support the existing concept that Ewing's sarcoma is strictly a "TET/ETS" fusion-driven malignancy. Understanding the molecular mechanisms of action of the various different fusion oncogenes will provide better insights into the biology underlying this rare but important solid tumor.

Ewing sarcoma is the second most frequent primary bone cancer affecting children or young adults. Advances in molecular biology have revealed common chromosomal translocations such as EWS-FLI1 among Ewing sarcoma and related diseases such as primitive neuroectodermal tumor (PNET), so these are considered as Ewing sarcoma family tumor (ESFT). Although fewer than 10% of patients with ESFT survived before establishment of modern multiagent chemotherapy, the multimodal therapeutic regimens including combination chemotherapy, radiotherapy, and surgery can cure 60% of patients with localized disease, due to the collaborative research in European-American or the international trials. The standard chemotherapy for localized ESFT now comprises vincristine, actinomycin D, cyclophosphamide and doxorubicin (VACD) in Europe or vincristine, doxorubicin, cyclophosphamide, ifosfamide and etoposide (VDC-IE) in North America. Meanwhile, those with metastatic disease have a much worse outcome with an approximately 10-30% 5-year event-free survival rate. New American-European collaborative trials such as EURO-E.W.I.N.G. 99 are in progress for further improvement of the cure rate in localized and metastatic ESFT. In Japan, Japan Ewing Sarcoma Study Group (JESS) phase II clinical trial for localized ESFT, and some clinical trials including new drugs are ongoing and waiting for results. (author)

Review of current data from the Intergroup Ewing Sarcoma Study (IESS) shows that Ewing sarcoma is rare in bones of the hands and feet. The 12 patients from the IESS protocols with hand or foot Ewing sarcoma are comparable to those already reported in the literature. With the exception of lesions in the calcaneus, the prognosis for disease-free survival is excellent. The radiographic features of hand and foot Ewing sarcoma are generally those of classic Ewing sarcoma: permeation, soft-tissue mass, and often, associated sclerotic reaction. However, with the exception of sclerosis, features suggesting bone reaction and slow tumor growth in these patients were distinctly uncommon compared with Ewing sarcoma in general. Apparently location of the lesion is important, since in the reported cases in the literature and in this series, lesions of the calcaneus fared poorly. The importance of this set of patients therefore relates to awareness and early recognition of an unusual appearance and location of Ewing sarcoma

Using of activated carbon to remove organic matter from phosphoric acid in uranium and P 2 O 5 extraction units has high cost. A new study was conducted to establish a new material instead of activated carbon. Experiments were carried out on removing organic matter by adsorption on Syrian bentonite. The experiments of the removal of humic acid by Syrian bentonite gave good results and showed that the chemical and thermal activation of bentonite increased the adsorption efficiency. (Authors)

Full Text Available The wave of democracy the Arab Spring Caused got started in 18 December 2010, after a university graduate stallholder's stall has been taken hold of and his burning himself to protest government led to o range of event in Tunisia deeply affected Syria by causing populations to pay for this. The Syrian Civil War started in March 2011 and it was seen as a result of Arab Spring, that noteworthy affects this region. But, although it had been a few years the Arab Spring hasn't come to Syria yet. While Syrian people,neighbor countries and the people in the region were all waiting for the spring to come, the rising of the Civil Wars and the affects of military, political and the economics sports of the countries that Syrian Regime politically, economically and commercially aligned with, had been turned into a humanitarian tragedy. As a result of the civil attacks of the Regime of Syrian to his people, around 300.000 people did,around 6.5 million people have been displaced, the numbers of the people need help increased to 10 million and so the number of the Syrian refugees in the neighbor countries reached to 3.795.284. As a result of this civil war in Syria 1.679.963 Syrian Arab Republic citizens have come to our country as refuges since 2011. The number of Syrian refugees reached 326 333 in Gaziantep Province. In this study, distribution by province of Syrian refugees in Turkey, and reflections of refugees in Gaziantep province are analyzed

1996-01-01

A nationwide investigation of radon levels in Syrian houses was carried out during the period 1991-1993. Passive radon diffusion dosemeters using polycarbonate detectors were distributed in houses all over Syria. Detectors were subjected to electrochemical etching to reveal latent tracks of alpha particles. The mean radon concentration in Syrian houses was found to be 45 Bq m -3 with some values several times higher. This investigation indicated that there were a few houses in Syria that require remedial action. Most houses that have high levels of radon were found in the southern area, especially in the Damascus governorate. The study also indicated that radon concentrations were higher in old houses built from mud with no tiling. (author)

Introduction Many Syrians have left their country and migrated to other countries since March 2011, due to the civil war. As of March 2016, a total of 2,747,946 Syrian refugees had immigrated to Turkey. Some Syrian refugees have been living in camps, while 2,475,134 have been living in metropolitan areas, such as Ankara. Study Objective This study investigated Emergency Medical Service (EMS) utilization among Syrian refugees residing in Ankara. This study was a descriptive, cross-sectional database analysis using data obtained from the Department of EMS of the Ankara Provincial Health Directorate. Five stations in the Altındağ region of Ankara responded to 42% of all calls from Syrian refugees. Prehospital EMS in Ankara have been used mostly by Syrian refugees younger than 18-years-old. Study findings also suggest that medical staff in regions where Syrian refugees are likely to be treated should be supported and provided with the ability to overcome language barriers and cultural differences.

Low pasture allowance during gestation affects ewes' BW at parturition, the bond with their lamb, lamb development, and thus also may affect their responses to weaning. The objectives were to determine if native pasture allowance from before conception until late pregnancy affects ewe-lamb behaviours at lambing, ewes' milk yield, lambs' BW, and the behavioural and physiological changes of ewes and lambs at weaning. From 23 days before conception until 122 days of pregnancy, 24 ewes grazed on two different native pasture allowances: high (10 to 12 kg of dry matter (DM)/100 kg of BW per day; HPA treatment; n=12) or low (5 to 8 kg of DM/100 kg of BW per day; LPA treatment; n=12). Thereafter, all ewes grazed on Festuca arundinacea and received rice bran and crude glycerine. Ewes' body condition score (BCS) and BW were recorded during pregnancy and postpartum periods. Milk yield was determined on days 32, 41 and 54 after lambing. Lambs' BW was recorded from birth until 72 days after lambing. Latency from parturition until the ewe licked her lamb, maternal behaviour score (a test that evaluates maternal attachment to the lamb) and latency for lamb to stand up and suckle were determined. The behaviour of the lambs and ewes was recorded before and after weaning (at 65 days). The ewes' serum total protein, albumin and globulin concentrations were measured before and after weaning. The HPA ewes presented greater BW (Pewes during pregnancy and postpartum (Pewes (Pewes' behavioural and physiological changes at weaning. HPA lambs paced and vocalized more than LPA lambs (Pewes' BW, BCS and milk production were affected by pasture allowance until late pregnancy, this did not affect the behaviours that lead to the establishment of the mother-young bond, nor the ewes' behavioural responses at weaning. Lambs reared by ewes that grazed on low pasture allowance during pregnancy presented fewer behavioural changes and a lower decrease of albumin concentration after weaning. Lambs' BW

2011-04-01

The aim of this study was to identify whether there was any difference in patient, tumour, treatment or outcome characteristics between patients with skeletal or extra-skeletal Ewing's sarcoma. We identified 300 patients with new primary Ewing's sarcoma diagnosed between 1980 and 2005 from the centres' local database. There were 253 (84%) with skeletal and 47 (16%) with extra-skeletal Ewing's sarcomas. Although patients with skeletal Ewing's were younger (mean age 16.8 years) than those with extra-skeletal Ewing's sarcoma (mean age 27.5 years), there was little difference between the groups in terms of tumour stage or treatment. Nearly all the patients were treated with chemotherapy and most had surgery. There was no difference in the overall survival of patients with skeletal (64%) and extra-skeletal Ewing's sarcoma (61%) (p = 0.85), and this was also the case when both groups were split by whether they had metastases or not. This large series has shown that the oncological outcomes of Ewing's sarcoma are related to tumour characteristics and patient age, and not determined by whether they arise in bone or soft tissue.

The objective of this study was to investigate the effects of partial replacement of wheat hay with sun-dried (SOC) or acid-treated SOC (ASOC) olive cake on nutrient intake and performance of Awassi lambs. An additional objective was to study the effects of acid treatment of olive cake (OC) on its chemical composition and nutritive value. On DM basis, sun-drying of OC did not dramatically affect its chemical composition. On the other hand, treating SOC with phosphoric acid decreased (pcomparison with the CTL diet, but not different from the ASOC diet. Additionally, lambs fed the SOC diet had greater (p = 0.03) hot and cold carcass weights than the ASOC diet, but not different from the CTL diet. However, feed conversion ratios and dressing percentages were similar among dietary treatments. In conclusion, replacing half of dietary wheat hay with SOC improved performance of Awassi lambs with no detrimental effects on nutrients intake or digestibility. No further improvements in the nutritive value of SOC and lambs performance were detected when SOC was treated with acid.

The increasing flow of Syrian refugees to Turkey, coupled with their extended stay, highlights the need for culturally competent health care, which includes nursing interventions. The purpose of this study was to describe the experiences of nurses who provide care for Syrian refugees in internal medicine clinics in a hospital located in Turkey. This descriptive study was based on qualitative content analysis using an inductive approach and involved discovery and description of the data. The study sample consisted of 10 nurses who work at the internal medicine clinic of a State Hospital in Turkey. Data were collected using semistructured interviews. Three themes with related subthemes were derived from the data. Nurses who participated in the study experienced: (a) Nurses found communicating with Syrian refugees and their families difficult in the clinic. (b) Nurses observed and experienced differences and similarities in caring for Turkish and Syrian patients. (c) Nurses expressed and displayed compassion toward Syrian refugees during the caring process. In order for nurses to provide the best care for Syrian refugee patients, it is important to identify cultural caring behaviors observed by nurses in the promotion of culturally congruent nursing and health care.

2015-01-01

Full Text Available Ewing's sarcoma or Ewing tumor is a rare primary bone tumor that affects mainly children and adolescents. It belongs to a group of cancers known collectively as Ewing sarcoma family tumors or Ewing family tumors. By the time, the patients present and diagnosis is made, the disease is usually advanced. We reviewed the case files of two patients managed in our hospital within one (2013. Fine-needle aspirations for cytology (FNAC and tissue biopsy were used for diagnosis in the two patients we had. The two patients, both males aged 20 years and 38 years presented late and FNAC and tissue biopsy revealed Ewing's sarcoma. They were referred for radio- and chemotherapy. However, due to poor socioeconomic status, they died of their primary disease. Unless diagnosed early, and in the absence of a multidisciplinary approach, Ewing's sarcoma is a fatal disease.

Procholecystokinin as marker of human Ewing sarcomas

PURPOSE: Ewing sarcoma is a rapidly growing mesenchymal tumor in young adults. Although it was shown previously to express the cholecystokinin (CCK) gene, it is unknown whether CCK gene expression is detectable at protein level in Ewing sarcoma tumor cell lines, in tumor tissue, and in plasma from...... Ewing sarcoma patients, and, if so, whether CCK peptides might play a role as tumor markers. EXPERIMENTAL DESIGN: CCK gene expression was evaluated with in situ hybridization or reverse transcription-PCR in tumor tissue. CCK precursors and bioactive CCK were measured with specific RIAs in tumor tissue......, in cell culture medium, and in plasma of Ewing sarcoma patients before and after chemotherapy as well as after tumor recurrence. RESULTS: CCK mRNA was identified in 12 Ewing sarcoma biopsies sampled in two series and in four Ewing sarcoma cell lines but not in unrelated neoplasia. Immunoreactive pro...

We retrospectively reviewed the medical records of all Syrian immigrants from the TurkishSyrian border who delivered the Zekai Tahir Burak Maternity and Teaching Hospital Neonatal Intensive Care Unit (NICU) in Ankara, Turkey. Between January 2013 and December 2014 a total of 36,346 women gave birth at this center. Of these, 457 women were Syrian immigrants, comprising 1.2 % (457/36,346) of all deliveries. The number of births among Syrian refugees in Turkey appears to be increasing. Further research is needed to understand the relative morbidity of babies born to Syrian refugees compared to the local population, as well as the economic impact on facilities treating these cases.

Ewing's sarcoma usually arises in the bones of children and adolescents. We herein report a 74-year-old man with Ewing's sarcoma in the adrenal gland. The diagnosis was confirmed by a genetic test, pathological studies, and several imaging studies. He already had multiple liver metastases when he was transferred to our hospital and died on the 37th day. The diagnosis was further confirmed by autopsy studies. Adrenal Ewing's sarcoma is very rare, and our patient was older than other reported cases. Ewing's sarcoma should be considered even in elderly patients with adrenal tumors.

Ewing's sarcoma of the patella.

Gorelik, Natalia; Dickson, Brendan C; Wunder, Jay S; Bleakney, Robert

2013-05-01

Ewing's sarcoma is a relatively rare malignancy, occurring mainly between 4 and 25 years of age. It usually arises from the pelvis, followed by the femur, tibia, and remainder of both the long bones of the extremities and flat bones of the axial skeleton. To the best of our knowledge, Ewing's sarcoma of the patella has never been reported previously. Patellar tumors occur infrequently and represent an uncommon etiology of anterior knee pain. We describe the rare case of a 41-year-old man who presented with a 3-4 month history of escalating right anterior knee pain and swelling. Imaging demonstrated an aggressive patellar tumor with an adjacent soft tissue mass. The diagnosis of Ewing's sarcoma was confirmed by pathology. Physicians should be aware of atypical locations for Ewing's sarcoma and, conversely, of rare tumors arising in the patella and accounting for anterior knee pain. Early recognition of such malignancies allows prompt initiation of treatment, hence improving prognosis.

We hypothesised that cocaine- and amphetamine-regulated transcript ( CARTPT ) would be differentially expressed in ewes with differing ovulation rates. Expression of mRNA for CARTPT , as well as LHCGR , FSHR , CYP19A1 and CYP17A1 was determined in antral follicles ≥1 mm in diameter collected during the follicular phase in ewes heterozygous for the Booroola and Inverdale genes (I+B+; average ovulation rate 4) and ++ contemporaries (++; average ovulation rate 1.8). In ++ ewes ( n  = 6), CARTPT was expressed in small follicles (1 to ewes. In I+B+ ewes, 5/6 ewes did not have any follicles that expressed CARTPT , and no CART peptide was detected in any follicle examined. Expression pattern of CYP19A1 differed between I+B+ and ++ ewes with an increased percentage of small and medium follicles (3 to ewes. Many of the large follicles from the I+B+ ewes appeared non-functional and expression of LHCGR , FSHR , CYP17A1 and CYP19A1 was less than that observed in ++ ewes. Expression of FSHR and CYP17A1 was not different between groups in small and medium follicles, but LHCGR expression was approximately double in I+B+ ewes compared to that in ++ ewes. Thus, ewes with high ovulation rates had a distinct pattern of expression of CARTPT mRNA and protein compared to ewes with normal ovulation rates, providing evidence for CART being important in the regulation of ovulation rate. © 2017 Society for Reproduction and Fertility.

Ewing's sarcoma of bone is a primary childhood malignancy of bone that is treated with X-radiation therapy in combination with surgical excision and chemotherapy. To better study Ewing's sarcoma of bone we developed a novel model of primary Ewing's sarcoma of bone and then treated animals with X-radiation therapy. We identified that uncontrolled tumor resulted in lytic bone destruction while X-radiation therapy decreased lytic bone destruction and increased limb-length asymmetry, a common, crippling complication of X-radiation therapy. Osteoclasts were indentified adjacent to the tumor, however, we were unable to detect RANK-ligand in the Ewing's tumor cells in vitro, which lead us to investigate alternate mechanisms for osteoclast formation. Ewing's sarcoma tumor cells and archival Ewing's sarcoma of bone tumor biopsy samples were shown to express MCSF, which could promote osteoclast formation. Increased monocyte numbers were detected in peripheral blood and spleen in animals with untreated Ewing's sarcoma tumor while monocyte number in animals treated with x-radiation had normal numbers of monocytes. Our data suggest that our Ewing's sarcoma of bone model will be useful in the study Ewing's sarcoma tumor progression in parallel with the effects of chemotherapy and X-radiation therapy.

Is There a Predisposition Gene for Ewing's Sarcoma?

Directory of Open Access Journals (Sweden)

R. L. Randall

2010-01-01

Full Text Available Ewing's sarcoma is a highly malignant tumor of children and young adults. The molecular mechanisms that underlie Ewing's Sarcoma development are beginning to be understood. For example, most cases of this disease harbor somatic chromosomal translocations that fuse the EWSR1 gene on chromosome 22 with members of the ETS family. While some cooperative genetic events have been identified, such as mutations in TP53 or deletions of the CDKN2A locus, these appear to be absent in the vast majority of cases. It is therefore uncertain whether EWS/ETS translocations are the only consistently present alteration in this tumor, or whether there are other recurrent abnormalities yet to be discovered. One method to discover such mutations is to identify familial cases of Ewing's sarcoma and to then map the susceptibility locus using traditional genetic mapping techniques. Although cases of sibling pairs with Ewing's sarcoma exist, familial cases of Ewing's sarcoma have not been reported. While Ewing's sarcoma has been reported as a 2nd malignancy after retinoblastoma, significant associations of Ewing's sarcoma with classic tumor susceptibility syndromes have not been identified. We will review the current evidence, or lack thereof, regarding the potential of a heritable condition predisposing to Ewing's sarcoma.

This research examines photojournalist’ perspectives of Syrian refugees in Europe, encoding, and dissemination processes. It employs a qualitative approach and functionalism perspective of mass media by sending questionnaires to voluntary respondents. The findings show sharing similar background and/or having experiences in the Middle Eastern countries highly influence the perspective of photojournalists on Syrian refugees. The encoding process covers through research of priority issues, target audience, trustworthiness of photos, and audience interpretation. The distribution method includes taking advantages of personal social media to promote the links of photos. As part of mass media industry, photojournalists play a crucial role to contribute to social integration, particularly, in creating a shared understanding between European community and Syrian refugees. The current research serves as a basis to future investigations on the perspective of European community towards Syrian refugees, whether or not their perspective is influenced by such photos.

Ewing Sarcoma: An Eponym Window to History

Full Text Available Ewing sarcoma was named after James R. Ewing, an eminent American pathologist at Cornell who described the first cases in 1921. Although he is best remembered for this singular achievement, Ewing's contributions to the study of cancer were far more profound and influential. He essentially launched oncology as a discipline with the publication of his seminal textbook and founded the major American cancer societies that exist today. His vision of comprehensive cancer centers still drives our research infrastructure. Since his initial report, these organizations have helped us achieve numerous milestones in understanding and treating patients with Ewing sarcoma.

To reveal these changing, the demographic and dermatological data of the Syrian refugees were retrospectively examined in faculty of medicine, department of dermatology of our city where a significant amount of Syrian refugees have been living. Materials and Methods: A total of 326 refugees immigrated to our city and have been living in tent cities, and applied to our department between September 2012-July 2014 were included to our study. Age, gender, dermatological and laboratory findings were retrospectively examined. Skin diseases were examined in 16 groups according to the their frequency. The patients were divided into 4 age groups as 0-20, 21-40, 41-60 and, 61 and over; three most common diseases for each age group were analyzed. Results: Of 326 patients, 126 (38.7% were males, 200 (61.3% were females and the difference was significant in term of gender. The age range of the patients was 0 to 77 years, and the mean age was 21.6±10.5. The majority of patients were in 0-20 age group. Dermatological infectious diseases were the most frequent diseases group and cutaneous leishmaniasis was the most diagnosed dermatological disease among patients. Conclusion: Preventive health care services should be performed to prevent dermatological infectious diseases which are commonly seen in Syrian refugees, especially cutaneous leishmaniasis which is already endemic in our country, and limitations to reach physicians of these patients should be amended.

Ewing sarcoma accounts for 10-15% of all childhood malignant bone tumours and is second in prevalence to osteosarcoma. The skull bones are an unusual site of origin of primary Ewing sarcoma in children. Previous reports concentrate on the neurosurgical aspects and relatively good outcome compared to other bone tumours of the calvarium. Reported cases mainly describe the imaging characteristics on CT. To describe the MRI and CT features of primary cranial Ewing sarcoma. The neuroimaging of three cases of primary cranial Ewing sarcoma are reviewed. Our three cases show an extra-axial mass that is high attenuation on CT and low signal on T2-weighted MRI. Haemorrhagic components, dural extension and contrast enhancement are also characteristic features. CT attenuation and magnetic resonance signal characteristics reflect sheets of densely packed cells seen in Ewing sarcoma. (orig.)

The effect of trade liberalisation on Syrian agriculture

Basel Abbas

2010-01-01

Full Text Available Syrian agricultural policy should be characterized by a high level of government intervention, including fixed prices, government monopoly in strategic crop marketing, government distribution of industrial fertilizers, significant barriers on food and agricultural commodities import and so on. Although there were certain changes and liberalization in this area during several last years, the Syrian agriculture remains as the most regulated sector of national economy in Near east and northern Africa.On the other hand, we may state the fact that Syrian governmental agriculture policy was successful considering so called strategic crops most of all in achieving self-sufficiency in wheat production, also an essential increase of cotton production volume which represents most important export crop of this near east country, took a part. Besides this progress there was restriction of disparity development in countryside and municipal household’s incomes, which is partial reason for slowing down of Syrian countryside poverty. These positive outcomes were reached at the expense of increasing go­vern­men­tal expenses and worsening of resources efficiency usage both in agriculture production and energy sectors. Considering forecasted spend of oil sources, the Syrian government will be ne­ce­s­sa­ri­ly forced to search for alternative resources of economic growth and government budget incomes in near future.The last five year country plan presumes consequental delimitation of grants and implication of value added tax. There is to be a quite large liberalisation in agriculture sector, which should lead to consequential down of wheat production, sugar beet and cotton and increase of barley, lentil and chickpea production.

Ewing's sarcoma is one of the most aggressive primary bone tumours. Ewing's sarcoma arising from the bones of the head and neck region is extremely rare; only 4–9% of all Ewing's sarcoma originate in this region. We report a case of Ewing's sarcoma localized in the mandible because of its unusual presentation.

Ewing's sarcoma (ES) or primitive neuro-ectodermal tumor (PNET) typically occurs in long or flat bones, the chest wall, extra-skeletal soft tissue, and rarely in solid organs. Incidence of adrenal Ewing's sarcoma is very rare. Here we report a case of Ewing's sarcoma of the right adrenal gland in an 8-year-old girl who presented with an abdominal mass. The huge tumor was managed by preoperative neo-adjuvant chemotherapy followed by surgical resection. She died due to metastasis after five months of surgery.

The aim of this study was to test if vitamin E supplementation during late gestation and early lactation would affect the weight of ewes under nutritional restriction and the performance of their lambs. Mature Rambouillet ewes (n = 37) were fed a diet that supplied 70 % of the energy and 80 % of recommended protein requirements and randomly assigned to either vitamin E (vit E, n = 20, 4 IU of α-tocopherol kg(-1) of live weight) or control (n = 17, without vitamin E supplementation). During the experimental period, the mean weight of ewes decreased from 74.6 ± 2.4 to 58.1 ± 2.2 kg. Weight loss of ewes was slightly less for the vit E than the control (-65 vs -124 g day(-1), SEM = 46; P = 0.07). Lambs born from vit E-supplemented ewes were heavier than lambs from the control and grew significantly faster (239 vs 195 g day(-1), SEM = 29.3, P ewes are not met, supplementation of vitamin E during late gestation and early lactation might be an effective strategy to minimise ewe weight loss as well as to increase lamb growth.

Ewing's sarcoma (or peripheral neuroectodermal tumour) is generally found in bone tissue, and a primary dermal site is extremely rare. We report a case of primary cutaneous Ewing's sarcoma in a 21-year-old woman. A 21-year-old woman presented with a scapular lesion that had been slowly developing for one year. The 1-cm lesion was removed and histological examination showed proliferation of small round cells in the dermis. Immunostaining revealed cytoplasmic membrane expression of CD99 and a negative immunoprofile for other small round-cell tumors. Ewing's sarcoma fusion gene transcripts were detected using fluorescence in situ hybridization (FISH). A staging examination revealed no other abnormalities. It was decided to treat the lesion as for osseous Ewing's sarcoma with wide resection followed by systemic adjuvant chemotherapy. Cutaneous Ewing's sarcoma raises concerns about diagnosis and treatment. Owing to the non-specificity of its clinical presentation, histology and immunoprofile, diagnosis of superficial Ewing's sarcoma is difficult and numerous differential diagnoses must be considered. When dealing with a surface tumour, the diagnosis of cutaneous Ewing's sarcoma must be considered. CD99 immunostaining and molecular testing for evidence of EWSR1 rearrangement are useful investigations to confirm the diagnosis. Furthermore, modalities of treatment must be carefully discussed. Cutaneous Ewing's sarcoma is currently treated in the same way as osseous Ewing's sarcoma (wide surgical excision, adjuvant radiotherapy when surgical margins are unsatisfactory, systemic adjuvant chemotherapy, and, in some cases, bone marrow transplant). However, some studies show a more favourable prognosis for cutaneous Ewing's sarcoma than for osseous Ewing's sarcoma. We may thus ask whether such aggressive multimodal treatment is needed.

Lebanon is the main hosting country for the Syrian crisis, with more than one million Syrian refugees. The objective of this study was to determine the prevalence of post-traumatic stress disorder (PTSD), and identify its possible predictors, in a sample of Syrian refugees living in camps in Lebanon. We conducted a household survey on Syrian refugees between 18 and 65years old in 6 camps of the Central Bekaa region, using the Mini International Neuropsychiatric Interview (M.I.N.I.) as a diagnostic tool. Among the 452 respondents, we found a lifetime prevalence of PTSD of 35.4%, and a point prevalence of 27.2%. The lifetime prevalence of SUD was 1.99% and the point prevalence 0.66%. Multivariate logistic regression could not identify any predictor of current PTSD among a list of demographic variables, but identified the Syrian hometown as a significant predictor of lifetime PTSD (p=.013), with refugees from Aleppo having significantly more PTSD than those coming from Homs (adjusted OR 2.14, 95% CI [1.28, 3.56], p=.004). PTSD was a real mental health issue in our sample of adult Syrian refugees in Central Bekaa camps, unlike SUD. Copyright © 2016 Elsevier Inc. All rights reserved.

Adversarial Framing: President Bashar al-Assad’s Depiction of the Armed Syrian Opposition

Full Text Available 'This paper evaluates how Syrian president Bashar al-Assad is framing his opponents in the context of the Syrian civil war. The question is addressed by conducting a qualitative thematic analysis of 13 interviews he gave to international television news networks and newspapers between March and November 2013. It is found that Al-Assad consequently labels the armed opposition as “terrorists” preponderantly composed of groups affiliated to Al-Qaeda. The “terrorists” are framed as posing a threat to the region as well as to international security on a global scale. Furthermore, Al-Assad denies the armed opposition its Syrian grassroots by portraying them as outside aggressors fighting for foreign interests. They are also depicted as “enemies of the Syrian people”, responsible for all the atrocities and human suffering committed during the Syrian civil war.' ' '

Normative data for plasma chemistry values in pregnant and non-pregnant reproductive age ewes are scant. Availability of data would aid monitoring of ewe health for both research and veterinary medicine. We determined specific plasma chemistry 95% confidence reference intervals (RIs) in non-pregnant and pregnant ewes. Mixed Western-breed ewes were grouped based on phase of ovarian cycle: luteal ( n = 15), follicular ( n = 17), or late-gestation pregnant ( n = 102). Plasma samples were collected for analysis on a commercial biochemical analyzer. For RIs, chemistry panels for the 3 groups of ewes included nutrients and metabolites (glucose, triglycerides, cholesterol, urea, creatinine, total protein, albumin, and bilirubin), enzymes (lactate dehydrogenase, aspartate transaminase, gamma-glutamyl transferase, alanine aminotransferase, and alkaline phosphatase [ALP]), and micronutrients (calcium, phosphorus, iron, sodium, potassium, and chloride). Sample chemistry values for glucose and total protein in pregnant ewes were lower than in follicular ewes; cholesterol was lower in pregnant and luteal ewes than in follicular ewes. In addition, total bilirubin in pregnant ewes differed from that in luteal ewes, and that in follicular ewes also differed from luteal ewes. ALP in pregnant ewes was higher than other groups; phosphorus in pregnant ewes was lower than in luteal ewes. Iron was higher in pregnant ewes than in luteal ewes, with iron in luteal ewes lower than in follicular ewes. These data provide clinical RIs comparing pregnant and non-pregnant ewes for use in monitoring ewe health in both human research and veterinary medicine.

To the best of our knowledge, the mental health status of physically injured Syrian refugees has not yet been investigated. The aim of this study was to examine the prevalence of psychiatric morbidity among physically injured Syrian refugees in Turkey receiving treatment at the main rehabilitation centre near the Syrian border. This is a cross sectional study. Information was collected from consenting injured Syrian refugees at Dar-el-Shefa'a Hospital in Reyhanlı (Turkey) during a one week period in December 2012 and another one week period in August 2013. A clinical psychiatric interview was conducted to determine a diagnosis according to the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM) IV-TR. A total of 40 refugees consented and completed a clinical psychiatric interview. All refugees in this study did not have a significant past psychiatric history. The most prevalent current diagnosis was major depressive disorder (22.5%), adjustment disorder (20%), and post-traumatic stress disorder (15%). Five (12.5%) patients had no evidence of a psychiatric disorder. The prevalence of psychiatric morbidity among injured Syrian refugees in our study was extremely high. This may help guide the treatment and management of this select population. This study had a low number of participants. The method of assessment was not standardized with a validated tool. This study may help guide the treatment and management of this select population, both in neighbouring countries and as resettled refugees in Western host countries. Copyright © 2017 Elsevier Inc.

Metastatic Ewing's sarcoma to the central nervous system is an uncommon condition and debate concerning the true origin of its metastases is still up to date. To the best of our knowledge, only two cases of dural metastatic Ewing's sarcoma have been published in the English medical literature. We present an additional case in a 24-year-old female and discuss the pathogenesis of these unusual tumors with review of the relevant literature concerning their treatment and outcome. A 24-year-old female with previous history of pelvis Ewing's sarcoma and recently discovered lung metastases, presented with moderate headache for the past 2 weeks and weakness in her left leg for the past 2 days. Computed tomography scan and magnetic resonance imaging revealed an extra-axial right frontoparietal mass invading the superior sagittal sinus but with clear delineation with brain parenchyma. Imaging features were suggestive of a meningioma as no abnormalities in the skull abutting to the tumor were noted. The patient underwent surgical removal of her tumor. Near total resection was achieved and histological examination showed evidence of metastatic Ewing's sarcoma. Postoperative adjuvant radiation and chemotherapy were administered. The patient improved well postoperatively with full recovery of her motor weakness. She is symptom free with no signs of progression, at most recent follow-up, 8 months after surgery. Despite its rarity, metastatic Ewing's sarcoma must be considered in the differential diagnosis of extra-axial dural masses particularly meningiomas.

1978-12-01

The effect of 2-bromo-..cap alpha..-ergocryptine (bromocriptine) on the induction and maintenance of milk secretion was studied in post-parturient ewes and in ovariectomized ewes artificially induced to lactate by treatment with oestrogen plus progesterone and then dexamethasone. Treatment with bromocriptine (about 0.4 mk/kg every 3 days) lowered and maintained the plasma concentration of prolactin at < 12 ng/ml. Ewes receiving bromocriptine concurrently with oestrogen plus progesterone during the priming phase had a significantly lower (P < 0.05) mean cumulative milk yield than control ewes, although the milk of the treated ewes contained normal amounts of fat, protein and lactose. Administration of bromocriptine during dexamethasone-induced lactogenesis had no significant effect on the mean cumulative milk yield but significantly (P < 0.05) increased the milk fat and protein content. In establishing lactation, bromocriptine markedly reduced the milk yield in both intact and ovariectomised ewes. The concentration of protein was not significantly affected although the milk fat content was higher in the bromocriptine-treated than in the control ewes. The effects of bromocriptine on milk yield and composition during galactopoiesis could be reversed by concurrent infusion of prolactin and the results suggest that prolactin is an important hormone during mammogenesis and galactopoiesis in sheep.

No study has investigated the availability and adherence of preventive oral care products on the Syrian market to evidence-based international recommendations. Data were collected in 2012, and updated in 2016, in terms of availability, characteristics and adherence to evidence-based international recommendations. Few preventive products adhered to the recommendations. Despite the large decrease in the number of oral care products on the Syrian market, due to the Syrian crisis, nonadherence of some of the available products is still present. A multisectorial approach at a policy level is needed to address such important limitations. The Syrian Ministry of Health should reform regulations for fluoride products to become subject to drug monitoring systems; the Syrian Arab Committee for Measurements and Standards needs to update its standards; and the Syrian General Dental Association should distribute a preventive booklet to dental practitioners.

This paper is based on a report commissioned by the United Nations High Commissioner for Refugees, which aims to provide information on cultural aspects of mental health and psychosocial wellbeing relevant to care and support for Syrians affected by the crisis. This paper aims to inform mental health and psychosocial support (MHPSS) staff of the mental health and psychosocial wellbeing issues facing Syrians who are internally displaced and Syrian refugees. We conducted a systematic literature search designed to capture clinical, social science and general literature examining the mental health of the Syrian population. The main medical, psychological and social sciences databases (e.g. Medline, PubMed, PsycInfo) were searched (until July 2015) in Arabic, English and French language sources. This search was supplemented with web-based searches in Arabic, English and French media, and in assessment reports and evaluations, by nongovernmental organisations, intergovernmental organisations and agencies of the United Nations. This search strategy should not be taken as a comprehensive review of all issues related to MHPSS of Syrians as some unpublished reports and evaluations were not reviewed. Conflict affected Syrians may experience a wide range of mental health problems including (1) exacerbations of pre-existing mental disorders; (2) new problems caused by conflict related violence, displacement and multiple losses; as well as (3) issues related to adaptation to the post-emergency context, for example living conditions in the countries of refuge. Some populations are particularly vulnerable such as men and women survivors of sexual or gender based violence, children who have experienced violence and exploitation and Syrians who are lesbian, gay, bisexual, transgender or intersex. Several factors influence access to MHPSS services including language barriers, stigma associated with seeking mental health care and the power dynamics of the helping relationship. Trust

2017-12-01

This study examined the coping strategies used by Syrian refugees in Jordan in relation to their demographics. A cross-sectional correlational study was conducted with a convenient sample of 550 Syrian refugees. Out of all the study participants, 88% reported seeking social support, 64.5% reported using avoidance, and 39.5% reported using problem solving. Participants who were male, single, and younger, and who had a higher education and a higher total income were satisfied with their income, were employed and free of chronic illnesses, and had higher problem-solving scores. Higher social support-seeking scores were associated with being female, older, and widowed; having a lower education and lower total income; being dissatisfied with their income; being nonemployed; and having chronic illnesses. A number of significant predictors were identified for each coping strategy. The results of this study could be used to formulate programs and develop services regarding the stressors encountered by Syrian refugees and their coping strategies.

Triplet-born lambs are less likely to survive to weaning than twin-born or single-born lambs. Appropriate ewe-lamb bonding behaviours and lamb vigour behaviours are necessary for survival of lambs. The aim of this experiment was to determine whether maternal nutrition during late pregnancy influenced behaviour of the ewe and her lambs soon after birth, and to determine whether mid-pregnancy body condition score (BCS) influenced any behavioural response. The experiments included ewes that were in BCS 2.0, 2.5 or 3.0 in mid-pregnancy and were fed either ad libitum or to pregnancy-maintenance requirements in late-pregnancy (day 115 until 136 in experiment one, and day 128 until 141 in experiment two). The time taken for lambs to stand, contact dam, suck from dam and follow dam was recorded three to 18 hours after birth. The number of high- and low-pitched bleats emitted by the ewe and lambs was recorded, along with maternal behaviour score (MBS) of the ewe. Lambs in experiment two underwent a maternal-recognition test at 12 or 24 h. There were significant effects of feeding treatment on bleating behaviour of ewes and lambs, but these were inconsistent among BCS groups and between experiments. Lamb vigour behaviours were not affected by feeding treatment. In experiment one, there was no effect of feeding treatment or BCS on MBS, but in experiment two, ewes in BCS3 in mid-pregnancy had greater MBS than ewes in BCS2 in mid-pregnancy (MBS 3.1/5 vs MBS 2.1/5; Pewes and lambs, ad libitum feeding rather than feeding for pregnancy-maintenance requirements can not be used to improve behaviours soon after birth of triplet-bearing ewes in BCS 2 - 3 and their lambs in extensive pastoral conditions.

Twenty pregnant Yankasa ewes were assigned to three groups to determine the effect of Trypanosoma evansi infection on pregnancy. Groups A and B comprising seven ewes each were infected with approximately 1.0 × 10(6) cells of T evansi per ewe through venepuncture at the second and third trimesters of pregnancy, respectively. Group C comprising six ewes served as uninfected control. There was slight pyrexia in the infected groups (groups A and B) but was absent in group C. The mean body weight, glucose concentration, and packed cell volume of ewes in group A were not significantly different from those in group C throughout the study. There was also no significant difference in mean glucose concentration between groups B and C. However, in group B, mean body weight was significantly (P ewes in group A was significantly (P ewes in group B decreased significantly (P ewes in the infected groups (groups A and B) compared with those in group C. However, there were significant (P ewes in group B compared with ewes in groups A and C. Mice inoculation with blood from infected ewes postpartum was parasitemic 18 to 25 days pi, for ewes in group B, whereas none of the mice in groups A and C were parasitemic. Lambs born from the infected groups (groups A and B) were also aparasitemic for 40 days postpartum. It was therefore concluded that the T evansi isolate used caused mild trypanosomosis when infected at third trimester, whereas ewes infected at second trimester were resistant.

Frantic Waiting: NGO Anti-Politics and "Timepass" for Young Syrian Refugees in Jordan

Directory of Open Access Journals (Sweden)

2017-12-01

Full Text Available Drawing on Sukarieh and Tannock's political economy of youth approach, this paper explores how Syrian refugee youth is constituted in protracted displacement in Jordan. It investigates a juvenile population often overlooked in Forced Migration Studies, disenfranchised rural Syrians, who fail to develop practices of youthfulness, yet in exile are subjected to alternative productions of youth by the aid sector. Depoliticized NGO youth programming overlooks Syrians' limited access to the labour market and higher education. While educational trainings aim to produce entrepreneurial and citizen refugees, they ultimately contribute to the creation of timepass and precarious lives. This research is grounded in fourteen months of ethnographic fieldwork with Syrian refugees in a border town in northern Jordan.

The aim of this study was to evaluate the demographic and clinical characteristics of Emergency Department (ED) visits made by Syrian refugees and to assess the cost of their healthcare. This retrospective study was conducted in adult Syrians who visited the ED of Adiyaman University Training and Research Hospital, Adiyaman Province, Turkey, between 01 January and 31 December 2015. We evaluated 10,529 Syrian refugees who visited the ED, of whom 9,842 were included in the study. The number of ED visits significantly increased in 2015 compared with 2010; the increase in the proportion of total ED visits was 8% (n = 11,275, dif: 8%, CI 95%: 7.9- 8.2, p refugees and the remaining 1.5% accounted for the visits made by other individuals. Upper respiratory tract infections (URTI) were the diseases most frequently presented (n = 4,656; 47.3%), and 68.5% of ED visits were inappropriate (n = 6,749). The median ED length of stay (LOS) of the Syrian refugees was significantly longer than that of the other individuals visiting the ED (p refugees who visited the ED was calculated as US$ 773,374.63. This study showed that Syrian refugees have increased the proportion of ED visits and the financial healthcare burden. The majority of ED visits made by Syrian refugees were inappropriate. In addition, their ED LOS was longer than that of other individuals making ED visits.

The Syrian conflict has displaced over 1.2 million Syrians into Lebanon. As a result of displacement, some Syrian families are turning to child marriage as a coping mechanism. The prevalence of early marriage has reportedly increased and the average age of marriage decreased during the crisis. The aim of the project was to understand the underlying factors contributing to child marriage among Syrian refugees in Lebanon using Cognitive Edge's SenseMaker®. This manuscript explores the process of implementing this novel research tool in a humanitarian setting. Twelve interviewers conducted SenseMaker® interviews with married and unmarried Syrian girls, Syrian parents, as well as married and unmarried men. Participants were asked to share a story about the lives of Syrian girls in Lebanon and to self-interpret the narratives by answering follow-up questions in relation to the story provided. Data collection occurred across three locations: Beirut, Beqaa, and Tripoli. In total 1422 narratives from 1346 unique participants were collected over 7 weeks. Data collection using SenseMaker® was efficient, capable of electronically capturing a large volume of quantitative and qualitative data. SenseMaker® limitations from a research perspective include lack of skip logic and inability to adjust font size on the iOS app. SenseMaker® was an efficient mixed methods data collection tool that was well received by participants in a refugee setting in Lebanon. The utility of SenseMaker® for research could be improved by adding skip logic and by being able to adjust font size on the iOS app.

Diagnosis and treatment of Ewing's sarcoma

International Nuclear Information System (INIS)

Iwamoto, Yukihide

2007-01-01

Ewing's sarcoma is a small round-cell tumor typically arising in the bones, rarely in soft tissues, of children and adolescents. Ewing's sarcoma has retained the most unfavorable prognosis of all primary musculoskeletal tumors. Prior to the use of multi-drug chemotherapy, long-term survival was less than 10%. The development of multi-disciplinary therapy with chemotherapy, irradiation, and surgery has increased current long-term survival rates in most clinical centers to greater than 50%. In addition, the preferred method of tumor resection has changed; limb salvage has nearly replaced amputation of the affected limb. Limb salvage procedures can be performed in place of amputation without compromising patient survival rates. Recent studies have revealed that the pathognomonic translocations involving the EWS gene on chromosome 22 and an ETS-type gene, which is most commonly the Fli1 gene on chromosome 11, are implicated in more than 95% of Ewing's sarcomas, primitive neuroectodermal tumors and Askin's tumors. Therefore, these lesions have become regarded as a single entity, dubbed the Ewing's family of tumors. Reverse transcription polymerase chain reaction (RT-PCR) to detect EWS-ETS gene arrangements is widely used to confirm the diagnosis of Ewing's family of tumors. Experimental results suggest that inhibition of the signaling pathway downstream of the EWS-ETS gene may lead to the development of molecularly targeted therapy in the future. (author)

2016-01-01

Since March 2011, an estimated 600,000 Syrian refugees crossed into Jordan, of which 52% were children. Demand for health care is overwhelming. The burden of heart disease in Syrian refugee children is not known. The aim of this study WAS to describe heart disease in Syrian refugee children in terms of diagnoses, presentation, outcome, and funding sources for treatment. From April 1, 2012 to April 30, 2014, data on Syrian refugee children who were referred to the Pediatric Cardiology Department at Jordan University Hospital and were found to have heart disease was recorded. In this study, we describe diagnoses, presentations, complications, and mortality. We discuss therapeutic procedures and their funding sources. Patients were followed until July 31, 2014. In all, 119 children, median age 2 years (6 days to 16 years), were diagnosed with heart disease. At presentation, 37% had failure to thrive, 13% had severe complications, and 32% of cyanotic patients had severe hypoxia with oxygen saturation of Syrian refugee children constitutes a major problem for both patients and health systems of host countries. Late presentation and diagnosis, high rate of complications, suboptimal living conditions, lack of funding, shortage of specialized centers and personnel, and high mortality rates are among the major challenges facing this patient population.

Full Text Available It is estimated by some authors that the administration of subcutaneous melatonin implants during a period of 30 days, in lactating or dry ewes, would improve the reproductive performance in some sheep breeds. This study was conducted in Giarmata Mare, Timis County, on 78 lactating ewes and 75 dry ewes, which were individually inserted with implants containing 18 mg melatonin on 31 August 2009. Control group consisted of 100 lactating and dry ewes in equal proportions. The results shown that the main reproduction indices as prolificacy, birth rate and the lamb number productivity index are significantly (p < 0.05 higher in ewes from the experimental group, compared with ewes from the control group, and that treated ewes shortened the period of mating and lambing to half-time comparing to the control group. There is a suggestion that the use of melatonin implants Melovin ® type near the normal breeding season increases the reproductive performance of ewes from Turcana breed.

Copy Number Alterations and Methylation in Ewing's Sarcoma

Jahromi, Mona S.; Jones, Kevin B.; Schiffman, Joshua D.

2011-01-01

Ewing's sarcoma is the second most common bone malignancy affecting children and young adults. The prognosis is especially poor in metastatic or relapsed disease. The cell of origin remains elusive, but the EWS-FLI1 fusion oncoprotein is present in the majority of cases. The understanding of the molecular basis of Ewing's sarcoma continues to progress slowly. EWS-FLI1 affects gene expression, but other factors must also be at work such as mutations, gene copy number alterations, and promoter methylation. This paper explores in depth two molecular aspects of Ewing's sarcoma: copy number alterations (CNAs) and methylation. While CNAs consistently have been reported in Ewing's sarcoma, their clinical significance has been variable, most likely due to small sample size and tumor heterogeneity. Methylation is thought to be important in oncogenesis and balanced karyotype cancers such as Ewing's, yet it has received only minimal attention in prior studies. Future CNA and methylation studies will help to understand the molecular basis of this disease. PMID:21437220

2017-07-25

The Syrian conflict has displaced five million individuals outside their country with Lebanon hosting the largest numbers per capita. Around 24% of Syrian refugees fleeing to Lebanon are women of reproductive age (15-49). Yet, a better understanding of the sexual and reproductive health needs of Syrian refugee women in Lebanon is required to improve provided services. Eleven focus group discussions were conducted in four regions of Lebanon with 108 Syrian refugee women of reproductive age. Thematic analysis was used to examine the data. Interviewed women were mainly adults. They believed that, in Lebanon, they were subjected to early marriage compared to the norm in Syria due to their financial situation and uncertainty. Cost was reported as the main barrier to use contraception in Lebanon but some Syrian refugee women were not aware of free services covering sexual and reproductive health. In general, marriage, pregnancy, and family planning behavior of Syrian refugee women in Lebanon slightly differed from those in Syria pre-conflict in terms of age of marriage, conception subsequent to marriage, and contraception method. Hence, interventions to increase awareness of subsidized sexual and reproductive health services, including free contraceptives at primary health care centers, and those targeting protection from early marriage of Syrian refugee women in Lebanon are strongly recommended.

The importance of prolactin for lactation in the ewe

Hooley, R.D.; Campbell, J.J.; Findlay, J.K.

1978-01-01

The effect of 2-bromo-α-ergocryptine (bromocriptine) on the induction and maintenance of milk secretion was studied in post-parturient ewes and in ovariectomized ewes artificially induced to lactate by treatment with oestrogen plus progesterone and then dexamethasone. Treatment with bromocriptine (about 0.4 mk/kg every 3 days) lowered and maintained the plasma concentration of prolactin at < 12 ng/ml. Ewes receiving bromocriptine concurrently with oestrogen plus progesterone during the priming phase had a significantly lower (P < 0.05) mean cumulative milk yield than control ewes, although the milk of the treated ewes contained normal amounts of fat, protein and lactose. Administration of bromocriptine during dexamethasone-induced lactogenesis had no significant effect on the mean cumulative milk yield but significantly (P < 0.05) increased the milk fat and protein content. In establishing lactation, bromocriptine markedly reduced the milk yield in both intact and ovariectomised ewes. The concentration of protein was not significantly affected although the milk fat content was higher in the bromocriptine-treated than in the control ewes. The effects of bromocriptine on milk yield and composition during galactopoiesis could be reversed by concurrent infusion of prolactin and the results suggest that prolactin is an important hormone during mammogenesis and galactopoiesis in sheep.

The present study aimed to determine the impact of ewe body condition score (BCS) (over a range of 2.0 to 3.0) and nutritional treatments (consisting of differing herbage masses) during very late pregnancy and lactation and their potential interaction on the performance of twin-bearing ewes and their lambs to weaning. On day 142 of pregnancy, twin-bearing ewes with a BCS of 2.0, 2.5, or 3.0 were allocated to a "Moderate' or 'Unrestricted' nutritional treatment until day 95 of lactation (weaning). The nutritional treatments aimed to achieve average herbage masses of 1,200 to 1,300 kg dry matter (DM)/ha (Moderate) and 1,500 to 1,800 kg DM/ha (Unrestricted). There were no three-way interactions between ewe BCS group, nutritional treatment and time for any ewe or lamb parameter. The nutritional treatments had no effect (p>0.05) on lamb birth or weaning weight. Lambs born to Moderate ewes had greater survival and total litter weight at weaning (pewes had greater body condition and back-fat depth at weaning than Moderate treatment ewes (pEwes of BCS 2.0 group reared lighter lambs to weaning (pewes. This study suggests farmers should aim to have all ewes with a BCS of 2.5 or 3 in late pregnancy for optimal lamb weaning performance. Furthermore, there is no benefit to lamb production of offering ewes pasture masses >1,200 kg DM/ha during very late pregnancy and lactation.

Space allowance recommendations for pregnant ewes vary considerably. The aim of this experiment was to investigate the effect of space allowance and floor type on activity, lying position, displacements, and aggressive interactions in pregnant ewes. A 3 × 2 factorial experiment was conducted with space allowance (0.75, 1.50, and 2.25 m/ewe) and type of flooring (straw bedding and expanded metal flooring) as the main factors. A total of 48 pregnant ewes were randomly assigned to 6 groups with 8 ewes in each group. All groups were exposed to each treatment for 7 d. The ewes were video recorded for 24 h at the end of each treatment period and general activity, lying position in the pen, and social lying position were scored every 15 min. Displacements and aggressive interactions were scored continuously from 1030 to 1430 h. Mean lying time ( flooring had no significant effect on general activity. Ewes in the straw bedding treatment spent more time lying in the middle of the pen than ewes on expanded metal ( flooring. Hence, recommended space allowance for pregnant ewes should not be lower than 1.50 m/ewe.

NORM waste management in the oil and gas industry. The Syrian experience

International Nuclear Information System (INIS)

Al-Masri, M.S.; Suman, H.

2003-01-01

Syrian experience with respect to naturally occurring radioactive materials (NORM) waste produced by the Syrian oil industry is described. Three main categories of NORM waste were identified. First, hard scales from decontamination of contaminated equipment and tubings which are considered to contain the highest levels of radium isotopes ( 226 Ra, 228 Ra, 224 Ra); this type of waste being currently stored in standard barrels in a controlled area. Second, sludge wastes containing low levels of radium isotopes were found in large amounts in each Syrian oilfield; plastic lined disposal pits were constructed in each area for temporary storage. However, disposal criteria for the above two categories of NORM waste are still under discussions. Third, soil contaminated with NORM as a result of uncontrolled disposal of production water was also considered as NORM waste. The Syrian criteria for disposal and clean up of this type of waste has been defined and approved by the Regulatory Office. (author)

Ideological Tensions in the Ranks of Syrian Officers: the Trigger of Military Circles Transformation in the Country?

Jana Kostrounova

2012-06-01

Full Text Available Despite the research by some authors on the Syrian Arab Republic and its stand in the Middle East Region, little is known about the perspective of the Syrian military, unofficially called the “elder statesman”, who rules this country. The overall image that emerges not only from the Arab media during the revolutionary year 2011 is ambivalent: lazy, corrupt, unpatriotic, apathetic soldiers with poor fighting spirits versus the Free Syrian Army newly formed in July 2011. This paper recovers some perspectives of the Syrian revolt and tries to answer, whether or whether not is the newly based military opposition in the country a real threat to the Assad regime. An analysis of historical background, Syrian veterans, relation between the official political doctrine and Islam brings new perspectives and own explanations that could even challenge some of the widely held assumptions about the Syrian military: 1 There is and won’t be any “civil war” in the Syrian Arab Republic at all; this conflict should be viewed as Islamic fitna and its roots come from the 1970’s. It is a regime strongly connected to rife corruption at the top ranks, hurting the morale of the lower, but stronger Islamic ranks; 2 Doctrinal relations between the Syrian army and official religious authorities in the Muslim world have been always tense; and 3 The Syrian army would have found the necessity of its own, inner transformation despite of the so-called “Arab Spring 2011”. This paper suggests that the character of the Syrian national revolt may be intended to reflect a deeper ideological antagonism between the Sunni and Shia Islam.

FOXM1 is an oncogenic mediator in Ewing Sarcoma.

Directory of Open Access Journals (Sweden)

Laura Christensen

Full Text Available Ewing Family Tumors (Ewing Sarcoma and peripheral Primitive Neuroectodermal Tumor are common bone and soft tissue malignancies of childhood, adolescence and young adulthood. Chromosomal translocation in these tumors produces fusion oncogenes of the EWS/ETS class, with EWS/FLI1 being by far the most common. EWS/ETS chimera are the only well established driver mutations in these tumors and they function as aberrant transcription factors. Understanding the downstream genes whose expression is modified has been a central approach to the study of these tumors. FOXM1 is a proliferation associated transcription factor which has increasingly been found to play a role in the pathogenesis of a wide range of human cancers. Here we demonstrate that FOXM1 is expressed in Ewing primary tumors and cell lines. Reduction in FOXM1 expression in Ewing cell lines results in diminished potential for anchorage independent growth. FOXM1 expression is enhanced by EWS/FLI1, though, unlike other tumor systems, it is not driven by expression of the EWS/FLI1 target GLI1. Thiostrepton is a compound known to inhibit FOXM1 by direct binding. We show that Thiostrepton diminishes FOXM1 expression in Ewing cell lines and this reduction reduces cell viability through an apoptotic mechanism. FOXM1 is involved in Ewing tumor pathogenesis and may prove to be a useful therapeutic target in Ewing tumors.

The Perspective of Trabzon Public on the Syrians in the Scope of Temporary Protection

2016-12-01

Full Text Available As a result of the crisis environment that started in Syria in March 2011 and the conflicts that have been going on until today, millions of Syrians have had to leave their countries in order to provide life and property security and to find better life opportunities. They have migrated towards foremost Turkey, Lebanon, Iraq, Jordan and European Union (EU countries. This movement of the Syrians towards other countries deeply affects many countries. Due to the fact that Turkey is a neighboring country, it is one of the countries most affected by this process. Besides its geographical proximity, the presence of religious, historical and cultural ties has also been instrumental in making this effect more noticeable. The aim of this study is to determine the issues about Syrians who fled from the ongoing civil war in Syria and took refuge in Turkey from the point of view of the public in Trabzon. For this purpose, firstly, Trabzon public opinion has been established on the basis of acceptance of the Syrians within the temporary protection to Turkey and the perspective on how to manage and what to do about the policies envisaged for the Syrians. Then the predictions about the permanence of the Syrians in Turkey were put forward and the view of the people of Trabzon on the long term was evaluated. However, in the case of Trabzon, it was tried to reveal the thoughts and expectatitions of the Syrian people under temporary protection of the Turkish society.

2013-01-01

To find and evaluate characteristic magnetic resonance imaging (MRI) patterns for the differentiation between Ewing sarcoma and osteomyelitis. We identified 28 consecutive patients referred to our department for MRI (1.5 T) of an unclear bone lesion with clinical symptoms suggestive of Ewing sarcoma or osteomyelitis. MRI scans were re-evaluated by two experienced radiologists, typical MR imaging features were documented and a diagnostic decision between Ewing sarcoma and osteomyelitis was made. Statistical significance of the association between MRI features and the biopsy-based diagnosis was assessed using Fisher's exact test. The most clear-cut pattern for determining the correct diagnosis was the presence of a sharp and defined margin of the bone lesion, which was found in all patients with Ewing sarcoma, but in none of the patients with osteomyelitis (P < 0.0001). Contrast enhancing soft tissue was present in all cases with Ewing sarcoma and absent in 4 patients with osteomyelitis (P = 0.0103). Cortical destruction was found in all patients with Ewing sarcoma, 4 patients with osteomyelitis did not present any cortical reaction (P = 0.0103). Cystic or necrotic areas were identified in 13 patients with Ewing sarcoma and in 1 patient with osteomyelitis (P = 0.004). Interobserver reliability was very good (kappa = 1) in Ewing sarcoma and moderate (kappa = 0.6) in patients with osteomyelitis. A sharp and defined margin, optimally visualized on T1-weighted images in comparison to short tau inversion recovery (STIR) images, is the most significant feature of Ewing sarcoma in differentiating from osteomyelitis.

Reproductive performance of ewes grazing lucerne during different periods around mating.

Science.gov (United States)

Robertson, S M; Clayton, E H; Friend, M A

2015-11-01

High intake of lucerne pastures or feeding of other high quality diets during early pregnancy may increase embryo mortality, negating any benefit of improved nutrition on ovulation rate in ewes. This study was conducted to determine whether grazing ewes on lucerne (Medicago sativa) pastures for 7 days prior to and throughout joining would result in greater foetal numbers than if ewes were removed 7 days after the commencement of joining, or if ewes grazed senescent pasture throughout the joining period. Merino ewes (300) were allocated to two replicates of three treatments, grazing pastures between Days -7 and 36 of an unsynchronised, natural autumn joining. Grazing lucerne to Day 7 of joining resulted in 30% more (Pewe than grazing senescent pasture (1.60±0.07 and 1.31±0.07, respectively), and 19% more lambs marked per ewe joined. Extending grazing of lucerne past Day 7 of joining did not result in additional foetuses per ewe (1.61±0.06) in comparison with only grazing lucerne to Day 7 of joining. Greater than 80% of ewes mated during the first 14 days of joining, and the proportions of ewes returning to oestrus and re-mating (0.18±0.022) and of non-pregnant (0.09±0.017) ewes were similar (P>0.05) among all treatment groups, suggesting no differences between treatments in embryo mortality. Grazing naturally cycling ewes on lucerne prior to and during joinings in autumn is recommended as a means to increase the number of lambs born, although additional gains may not be obtained by grazing past day seven of joining.

Husein, M Q; Haddad, S G

2006-06-01

The objective was to compare the effects of royal jelly (RJ) and eCG treatments on reproductive performance of ewes synchronized using intravaginal progesterone-releasing devices. Forty-two cycling Awassi ewes were treated intramuscularly (i.m.) with 15 mg PGF2alpha. On the following day, all ewes were administered with CIDR-G for 12 days and were randomly allocated to three (RJ, eCG and control) groups of 14 ewes each. Ewes in the RJ-treated group received daily i.m. treatments of 400mg RJ during the period of CIDR-treatment. Each ewe in the eCG-treated group received an i.m. treatment of 500 IU eCG at the time of CIDR-G removal (day 0) and no further treatment was given to ewes in the control group. Ewes were exposed to four fertile rams for 72 h, from the time of CIDR-G removal, and checked for breeding marks at 6-h intervals. Blood samples were collected from day -13 until day 0 and thereafter until day 19 for progesterone analysis. Royal jelly treatment resulted in a greater rate of decline and lower (Pprogesterone concentrations between days -10 and 0 than eCG-treated and control ewes. Expression of estrus was similar among the three groups and intervals to onset of estrus were shorter (P<0.01) in RJ-treated (31.3h) and eCG-treated (29.8h) than control (41.3h) ewes. First-cycle pregnancy and lambing rates were greater (P<0.05) in RJ-treated (71.4 and 71.4%) and eCG-treated (85.7 and 78.6%) than in control (42.9 and 35.7%) ewes, respectively. Results demonstrate that the treatments of RJ and eCG in conjunction with CIDR-G were similarly effective in induction of estrus and improvement of pregnancy and lambing rates.

Improvements in survival for Ewing sarcoma pediatric and adolescent patients have been modest over the past 20 years. Combinations of anticancer agents endure as an option to overcome resistance to single treatments caused by compensatory pathways. Moreover, combinations are thought to lessen any associated adverse side effects through reduced dosing, which is particularly important in childhood tumors. Using a parallel phenotypic combinatorial screening approach of cells derived from three pediatric tumor types, we identified Ewing sarcoma-specific interactions of a diverse set of targeted agents including approved drugs. We were able to retrieve highly synergistic drug combinations specific for Ewing sarcoma and identified signaling processes important for Ewing sarcoma cell proliferation determined by EWS-FLI1 We generated a molecular target profile of PKC412, a multikinase inhibitor with strong synergistic propensity in Ewing sarcoma, revealing its targets in critical Ewing sarcoma signaling routes. Using a multilevel experimental approach including quantitative phosphoproteomics, we analyzed the molecular rationale behind the disease-specific synergistic effect of simultaneous application of PKC412 and IGF1R inhibitors. The mechanism of the drug synergy between these inhibitors is different from the sum of the mechanisms of the single agents. The combination effectively inhibited pathway crosstalk and averted feedback loop repression, in EWS-FLI1-dependent manner.

A marked increase in the incidence of hypocalcemia of ewes 2 to 6 weeks before lambing was observed in the Western District of Victoria, following the break of the severe 1982/3 drought. A similar observation was made after the 1968 drought. In western Victoria, hypocalcemia is usually seen annually as sporadic cases or in sporadic outbreaks associated with some predisposing stress. After the drought broke in 1983, many farms reported cases of hypocalcemia in ewes. The incidence of hypocalcemia on the 9 farms the authors studied varied from 1 to 8% of all ewes, with some mobs having an incidence of over 10%. Detailed investigation of 9 farms that affected sheep were grazing pasture of unusually low calcium (Ca) content. Near record rains fell after the drought broke in late March 1983 resulting in luxuriant pasture growth with subterranean clover Trifolium subterraneum and capeweed Arctotheca calendula the dominant species. Cases of hypocalcemia commenced in May 1983 reaching a peak in June-July corresponding with flocks' lambing times, and continued into August. Most occurred spontaneously in mature ewes. A few farms experienced many cases during prelambing crutching.

In this study, we aimed to compare the Syrian refugees and resident Turkish pregnant population in terms of Toxoplasma seroprevalence. Data acquired from Kahramanmaraş Necip Fazıl City Hospital Department of Obstetrics and Gynecology between 2012 and 2013 were analyzed retrospectively. Results of 7201 Toxoplasma IgM tests and 4113 Toxoplasma IgG tests were evaluated. For 2012 and 2013 Toxoplasma IgM seropositivity was found in Syrian refugees 4.76% and 4.84% respectively in our study. In the same population Toxoplasma IgG seropositivity rates were 80% and 62.6%, respectively. Toxoplasma IgM seropositivity rates for the native peoples in Turkey in 2012 and 2013 was 1.96% and 2.34%, while in the same population Toxoplasma IgG seropositivity was detected 49.7% and 45.7% respectively. Toxoplasma IgM seropositivity was statistically higher in Syrian refugees for each year (p Syrian refugees was statistically higher (p Syrian refugees living in the region of Kahramanmaraş were statistically higher than the rates of local inhabitants, we consider that this condition should be taken into account in the follow-ups of Syrian pregnant refugees outnumbering in Kahramanmaraş and its vicinity.

This experiment studied congenital transmission in sheep experimentally infected with oocysts of Toxoplasma gondii and reinfected at one of three stages of pregnancy. Twenty ewes were experimentally infected with T. gondii strain ME49 (day 0). After the T. gondii infection became chronic (IFAT≤512), the ewes were allocated with rams for coverage. After the diagnosis of pregnancy, these ewes were allocated into four experimental groups (n = 5): I-reinfected with T. gondii on the 40th day of gestation (DG); II-reinfected on DG 80; III-reinfected on DG 120; and IV-saline solution on DG 120 (not reinfected). Five ewes (IFATewes produced lambs serologically positive for T. gondii. The results of the mouse bioassay, immunohistochemistry and PCR assays revealed the presence of T. gondii in all 20 sheep and their lambs. The congenital transmission of T. gondii was associated with fetal loss and abnormalities in persistently infected sheep and in ewes infected and subsequently reinfected by this protozoan. Therefore, congenital T. gondii infection was common when ewes were chronically infected prior to pregnancy, with or without reinfection during at various stages of gestation.

This study used focus group discussions to explore 29 Syrian women's experiences of being displaced refugees in Lebanon. Women reported intimate partner violence (IPV), harassment, and community violence. They experienced difficult living conditions characterized by crowding and lack of privacy, adult unemployment, and overall feelings of helplessness. Most frequently, they used negative coping strategies, including justification and acceptance of IPV and often physically harmed their own children due to heightened stress. Some sought support from other Syrian refugee women. Although the study did not address the root causes of IPV, the results shed light on women's experiences and indicate that training them in positive coping strategies and establishing support groups would help them face IPV that occurs in refugee settings.

Cell Cycle Deregulation in Ewing's Sarcoma Pathogenesis

Science.gov (United States)

Kowalewski, Ashley A.; Randall, R. Lor; Lessnick, Stephen L.

2011-01-01

Ewing's sarcoma is a highly aggressive pediatric tumor of bone that usually contains the characteristic chromosomal translocation t(11;22)(q24;q12). This translocation encodes the oncogenic fusion protein EWS/FLI, which acts as an aberrant transcription factor to deregulate target genes necessary for oncogenesis. One key feature of oncogenic transformation is dysregulation of cell cycle control. It is therefore likely that EWS/FLI and other cooperating mutations in Ewing's sarcoma modulate the cell cycle to facilitate tumorigenesis. This paper will summarize current published data associated with deregulation of the cell cycle in Ewing's sarcoma and highlight important questions that remain to be answered. PMID:21052502

After more than three years of violence in Syria, Lebanon hosts over one million Syrian refugees creating significant public health concerns. Antenatal care delivery to tens of thousands of pregnant Syrian refugee women is critical to preventing maternal and fetal mortality but is not well characterized given the multiple factors obtaining health data in a displaced population. This study describes antenatal care access, the scope of existing antenatal care, and antenatal and family planning behaviors and practice among pregnant Syrian refugees in various living conditions and multiple geographic areas of Lebanon. A field-based survey was conducted between July and October 2013 in 14 main geographic sites of refugee concentration. The assessment evaluated antenatal services among a non-randomized sample of 420 self-identified pregnant Syrian refugee women that included demographics, gestational age, living accommodation, antenatal care coverage, antenatal care content, antenatal health behaviors, antenatal health literacy, and family planning perception and practices. In total, 420 pregnant Syrian refugees living in Lebanon completed the survey. Of these, 82.9% (348) received some antenatal care. Of those with at least one antenatal visit, 222 (63.8%) received care attended by a skilled professional three or more times, 111 (31.9%) 1-2 times, and 15 (4.3%) had never received skilled antenatal care. We assessed antenatal care content defined by blood pressure measurement, and urine and blood sample analyses. Of those who had received any antenatal care, only 31.2% received all three interventions, 18.2% received two out of three, 32.1% received one out of three, and 18.5% received no interventions. Only (41.2%) had an adequate diet of vitamins, minerals, and folic acid. Access, content and health behaviors varied by gestational age, type of accommodation and location in Lebanon. Standards of antenatal care are not being met for pregnant Syrian refugee women in

The intrarenal distribution of 125I-albumin in the syrian hamster

Moeller, P.

1977-01-01

The intrarenal distribution of radioiodinated human serum albumin ( 125 RISA) after intravenous injection was studied in Syrian hamsters by scintillation counting and frozen section autoradiogrpahy. After 15, 30, and 60 min the virtual plasma albumin space in the renal cortex of the hamster represented 6.49, 7.13, and 8.06% respectively of the kidney tissue volume. From the cortex to the renal papilla the albumin space increased to about 30% of the tissue volume. In comparison to this the albumin space in the renal cortex of the rat was about 20%, and in the renal papilla about 33% (11). Frozen section autoradiography indicated that the distribution of radioalbumin in the renal cortex if the Syrian hamster is limited mainly to the kidney vessels, being especially noticeable in the glomerular capillaries. Toward the papilla increasingly greater (mainly extratubular) activity could be observed not only intravascularly but also interstitially. In the cortex of the rat kidney, on the other hand, radioactive albumin was accumulated (probably by filtration and reabsorption) predominantly in the proximal tubular epithelium. Within 30 min the kidneys of the rat excreted more than 10 times as much 125 I than the hamster kidneys. These results (substantially less cortical accumulation and urinary excretion of radioalbumin in the Syrian hamster) indicate that, in contrast to the rat, obviously much less albumin is filtered (and then accumulated by proximal reabsorption) by the Syrian hamster glomeruli. This suggests that the Syrian hamster kidney is more suitable than the rat kidney for determining the interstitial, cortical, albumin space. (orig./AJ) [de

Ewing's sarcoma is a malignant bone tumor that can occur anywhere in the body, but it is most commonly observed in the long bones of the arms and legs, the pelvis and in the chest. The predominant sites of metastasis include the lung (38%), bone (including the spine; 31%), and the bone marrow (11%). Metastasis of Ewing's sarcoma to the central nervous system (CNS) is relatively rare, and most of the previous reports have demonstrated involvement of the bony calvarium or brain parenchyma. We describe here the imaging findings of dural metastasis of Ewing's sarcoma, and these imaging findings have not been previously reported on in the medical literature. In conclusion, dural metastasis of Ewing's sarcoma is very rare and its imaging characteristics are similar to those of a primary tumor, which mimic the findings of a schwannoma or meningioma. Despite its rarity, secondary Ewing's sarcoma may be included in the differential diagnosis of extra-axial dural masses

Changes in progesterone secretion in intact ewes (7 or 9 per breed) and luteinizing hormone secretion in ovariectomized, estradiol-implanted ewes (9 or 10 per breed) were monitored for 12 mo in Suffolk, tropically adapted St. Croix, and OOS ewes. The OOS line is a composite population of 50% Dorset, 25% Rambouillet, and 25% Finnish Landrace breeding that was selected for 10 yr for ability to lamb in October and early November. Ewes were isolated from rams, and blood samples were collected twice weekly. Circulating prolactin concentrations were also determined from blood samples collected near the summer and winter solstice and vernal and autumnal equinox. Intact OOS ewes entered anestrus later, began the subsequent breeding season sooner, and had a shorter seasonal anestrus than Suffolk and St. Croix ewes (P ≤ 0.005). St. Croix ewes did not differ from Suffolk ewes in date of onset or cessation of breeding or duration of anestrus (P ≥ 0.06). Breed differences in duration of luteinizing hormone inhibition in ovariectomized ewes were essentially identical to those observed for duration of anestrous. Prolactin concentrations varied during the year: annual changes were larger in relatively seasonal Suffolk ewes than in tropically-derived St. Croix ewes (Psheep did not have a shorter seasonal anestrus than Suffolk sheep under temperate conditions and ram isolation.

Full Text Available Vaginoscopy allows for diagnostic evaluation and treatment of the vaginal vault. A laparoscopic surgical port device and rigid telescope were utilized for serial vaginoscopy in 8 healthy anesthetized ewes. Vaginoscopy examinations were performed in each ewe at days 1, 14, and 28. This technique was well-tolerated and facilitated carbon dioxide vaginal inflation, complete vaginal examination, identification of the cervix, and targeted biopsy collection. No complications were encountered during or following the vaginoscopy procedures. The laparoscopic port device was well-suited to the ewe vulvar size. This technique could be applied to clinical evaluation in ewes for the purposes of examination, biopsy, culture, foreign body removal, and minor surgical procedures.

The Politics of Syrian Refugees in Turkey: A Question of Inclusion and Exclusion through Citizenship

Directory of Open Access Journals (Sweden)

Sebnem Koser Akcapar

2018-03-01

Full Text Available Turkey began to receive refugees from Syria in 2011 and has since become the country hosting the highest number of refugees, with more than 3.5 million Syrians and half a million people of other nationalities, mainly from Afghanistan, Iraq and Iran. An important turning point regarding the legal status of Syrian refugees has come with recent amendments to the Turkish citizenship law. Based on ongoing academic debates on integration and citizenship, this article will explore these two concepts in the case of Syrian refugees in Turkey. We will argue that the shift in the Turkish citizenship law is a direct outcome of recent migration flows. We further argue that the citizenship option is used both as a reward for skilled migrants with economic and cultural capital and as a tool to integrate the rest of the Syrians. It also reflects other social, political and demographic concerns of the Turkish government. Using our recent ethnographic study with Syrians and local populations in two main refugee hosting cities in Turkey, Istanbul and Gaziantep, we will locate the successes and weaknesses of this strategy by exemplifying the views of Syrian refugees on gaining Turkish citizenship and the reactions of Turkish nationals.

We sought to investigate the clinicopathological significance and biological function of hepatoma-derived growth factor (HDGF) in Ewing's sarcoma. Our results showed that HDGF expression is up-regulated in Ewing's sarcoma. Nuclear HDGF expression is significantly associated with tumour volume (p Ewing's sarcoma cell growth, proliferation and enhances tumourigenesis, both in vitro and in vivo. Meanwhile, HDGF knock-down causes cell cycle arrest and enhanced sensitization to serum starvation-induced apoptosis. Furthermore, recombinant HDGF promotes proliferation and colony formation of Ewing's sarcoma cells. Ninety-eight candidate HDGF downstream genes were identified in Ewing's sarcoma cells using cDNA microarray analysis. In addition, we found that HDGF knock-down inhibited FLI1 expression in Ewing's sarcoma cells at the mRNA and protein levels. Our findings suggest that HDGF exhibits oncogenic properties and may be a novel prognostic factor in Ewing's sarcoma. Targeting HDGF might be a potential therapeutic strategy for Ewing's sarcoma.

Notter, D R; Burke, J M; Miller, J E; Morgan, J L M

2017-01-01

Selection for low fecal egg counts (FEC) can be used to genetically enhance resistance to gastrointestinal nematode parasites in growing lambs, thereby reducing the frequency of use of anthelmintics, facilitating marketing of organic lamb, and reducing the risk of development of anthelmintic resistance by the parasite. Recording of FEC in lambs has, therefore, been incorporated into several national sheep genetic evaluation programs. Ewes in late gestation and early lactation are also vulnerable to parasite infection and commonly experience a periparturient rise in FEC. This study was designed to assess factors associated with the periparturient rise in FEC in Katahdin ewes and associated changes in FEC in their lambs. Data came from 1,487 lambings by 931 Katahdin ewes from 11 farms in the Eastern United States. Fecal egg counts were measured in ewes at approximately 0, 30, and 60 d postpartum and in their lambs at approximately 60, 90, and 120 d of age. Approximately 1,400 lambs were evaluated at each measurement age. Data were analyzed separately for ewes and lambs and also initially analyzed separately for each measurement time. Repeated-measures analyses were then used to evaluate responses across measurement times. In ewes, FEC peaked at approximately 28 d postpartum, and we concluded that informative periparturient FEC could be obtained from 1 wk before until approximately 5 wk after lambing. Yearling ewes had higher FEC than adult ewes ( ewes that nursed twin or triplet lambs had higher FEC than ewes that nursed single lambs ( ewes and lambs nursed in larger litters were, like their dams, at greater risk of parasitism ( Ewes and lambs in these groups would benefit from enhanced monitoring of parasite loads at lambing and in early lactation. Correlations () between FEC in lambs at 90 d of age and FEC in ewes at 0, 30, and 60 d postpartum of 0.05 to 0.09 ( ≤ 0.05) support the presence of a genetic relationship between these 2 indicators of parasite

Objective was to study, in an experimental model, the possible role of gastrointestinal nematode infection in predisposing ewes to mastitis during the lactation period. Twenty-four ewes (A or B [n=12]), free from nematode and trematode helminths, were used. Group A animals received 5000 third-stage larvae of a trichostrongylid helminth cocktail and group B ewes were unparasitised controls. Animals in group A developed gastrointestinal trichostrongylosis confirmed by >500epg in faecal samples; mean epg of group B ewes were Ewes were challenged by deposition of Mannheimia haemolytica into the teat duct. In group A, 7 ewes developed clinical and 5 subclinical mastitis; no ewe in group B developed clinical mastitis, but only subclinical (12 ewes) (P=0.002).

Full Text Available Assessment of bone mineral density (BMD using dual energy X-ray absorptiometry (DXA technique is considered as a standard technique for diagnosing osteopenia and osteoporosis and evaluating the severity of such diseases. Numerous studies have demonstrated the necessity to establish an ethnic-specific reference data for Bone mineral density measurements. Such data are lacking for the Syrian population. The objectives of this study are (1 to establish BMD reference values in a group of healthy Syrian women using DXA technique, (2 to compare with values from other populations, (3 to study the prevalence of osteopenia and osteoporosis in Syrian women using the manufacturer reference values. A total of 951 healthy Syrian women aged 20-79 years participated in this study. Weight, height, and BMI have been determined. BMD measurements were performed using Lunar Prodigy Advance System (GE. The data were compared with those from other populations. The results have demonstrated the expected decline in BMD with age after peaking at 30-39 years old group. The peak values of the lumbar spine and femur neck were 1.16 (0.12, and 0.95 (0.13 g/cm2, respectively. The results of the Syrian women were compared with those from other populations and the differences were presented. Osteopenia was diagnosed in 35.80% and 60.31% and osteoporosis in 6.23% and 2.72% in lumbar spine and femur neck, respectively, of women 50-59 years of age. These ratios increased to 36.84%, 68.42% and 23.68%, 13.10%, respectively, in the age group more than 59 years. BMD values of the Syrian women were determined for the first time. The results demonstrate the importance of establishing population-specific reference range for BMD values for an accurate assessment of Osteoporosis. High prevalence of osteopenia and osteoporosis was demonstrated in Syrian using the manufacturer reference values.

Congenital extraskeletal Ewing's sarcoma or peripheral primitive neuroectodermal tumor is an extremely uncommon and invariably fatal tumor. We report a case of extraskeletal congenital Ewing's sarcoma in a female fetus delivered at 34 weeks of gestation who died immediately after birth. In English literature, majority of cases of Ewing's sarcoma in neonates reported were skeletal. To the best of our knowledge, very few cases of extra-skeletal Ewing's sarcoma in neonates are reported in the literature.

Hormonal levels after ovarian X-irradiation of ewes

International Nuclear Information System (INIS)

Driancourt, M.A.; Blanc, M.R.; Mariana, J.C.

1983-01-01

The effects of X-irradiation on ovulation rate, cyclicity and progesterone and FSH levels in Ile-de-France ewes (4 control and 16 irradiated) after they were treated during the breeding season were reported. The doses used (800 and 2400 R) destroyed 50% of all size classes of the follicular population. Ovulation occurred in 87% of the treated ewes (ovulation rate = 1) when they were irradiated 24 h after luteolysis; 78% of the corpora lutea resulting from these ovulations were normal as to length and progesterone production. FSH in treated ewes started to increase 20 h after treatment and remained higher than in the controls until ovulation time. Later, while these levels were similar between groups on the day of ovulation, high ovulatory levels persisted in irradiated ewes. In the next cycles, the length of the follicular phases, ovulation rate and progesterone and FSH levels were similar between groups

Use of tritiated water for estimating body composition in grazing ewes

International Nuclear Information System (INIS)

Russel, A.J.F.; Foot, J.Z.; McFarlane, D.M.

1982-01-01

Tritiated water was used to estimate total body water, body composition and water turnover of non-pregnant, pregnant, non-lactating and lactating grazing sheep. Body composition was estimated from equilibrated and extrapolated values of tritiated water space. These methods both overestimated the total body water measured directly. Body fat could be predicted satisfactorily from tritiated water space within the physiological states of ewes, i.e. lactating, pregnant, etc., although for lactating ewes the error of prediction is greater. It appears inadvisable at this stage to use equations derived from all classes of ewes to estimate body fat in ewes of any one physiological state. Water turnover varied, with the physiological state being highest for lactating ewes. (author)

Indoor experiments are described that compare the transfer of radiocesium to ewe and lamb tissues from different sources. Lactating ewes were fed either perennial ryegrass contaminated by Chernobyl fallout, or saltmarsh vegetation contaminated by marine discharges from the Sellafield reprocessing plant. The transfer to ewe tissues and milk was greater from the Chernobyl contaminated herbage than from saltmarsh vegetation. Lambs receiving a mixture of vegetation and milk were given radiocesium from one of the two vegetation sources or from milk obtained from the experimental ewes. Transfer to lamb tissues declined in the order milk greater than Chernobyl fallout greater than Sellafield discharge. The radiocesium transfer to lamb tissues exceeded that to ewe tissues. Transfer coefficients for 137Cs in the Chernobyl fallout were higher than most previously published figures at 0.12 d kg-1 for ewe muscle and 0.50 d kg-1 for lamb muscle. The transfer coefficient for 137Cs from ewe milk to lamb muscle was 1.20 d kg-1

Ewing's sarcoma in childhood is a disease from family of the peripheral primitive neuroectodermal tumours. For a period of 16 y (1984-2000), 34 children with Ewing's sarcoma were treated and followed in our department. Twenty-seven of these patients were without distant metastases. Complex treatment was applied to all these patients-chemotherapy VACA (vincristine, actinomycin D, cyclophosphamide, adriamycin), local radiotherapy to a total dose of 50-56 Gy +/- surgery. After, a local tumour control was achieved in 11 children with non-metastatic Ewing's sarcoma, elective whole lung irradiation to a total dose of 12-15 Gy was applied. Our experience in these 11 patients with non-metastatic Ewing's sarcoma, in whom elective lung irradiation was applied, showed significant reduction in the lung metastases, improved free of disease survival and overall survival. The achieved good treatment results necessitate extending this treatment approach through defining the risk groups of patients, suitable for elective lung radiotherapy combined with chemotherapy in non-metastatic Ewing's sarcoma. © The Author 2015.

Alqahtani, Ali; Amer, Roaa; Bakhsh, Eman

2017-01-01

Ewing's sarcoma is a primary bone cancer that mainly affects the long bones. This malignancy is particularly common in pediatric patients. Primary cranial involvement accounts for 1% of cases, with occipital involvement considered extremely rare. In this case study, primary occipital Ewing's sarcoma with a posterior fossa mass and subsequent relapse resulting in spinal seeding is reported. A 3-year-old patient presented with a 1-year history of left-sided headaches, localized over the occipital bone with progressive torticollis. Computed tomography (CT) imaging showed a mass in the left posterior fossa compressing the brainstem. The patient then underwent surgical excision followed by adjuvant chemoradiation therapy. Two years later, the patient presented with severe lower back pain and urinary incontinence. Whole-spine magnetic resonance imaging (MRI) showed cerebrospinal fluid (CSF) seeding from the L5 to the S4 vertebrae. Primary cranial Ewing's sarcoma is considered in the differential diagnosis of children with extra-axial posterior fossa mass associated with destructive permeative bone lesions. Although primary cranial Ewing's sarcoma typically has good prognosis, our patient developed metastasis in the lower spine. Therefore, with CNS Ewing's sarcoma, screening of the entire neural axis should be taken into consideration for early detection of CSF seeding metastasis in order to decrease the associated morbidity and mortality.

Full Text Available The media coverage of women migrations has played an important role in shaping public opinion and governmental policies. This article aims at exploring the media portrayals of Syrian Migrant Women in Turkey. For this purpose, the research data were collected from the three Turkish online newspaper websites, Hürriyet, Birgün and Sabah, each of which has different editorial policy in representing migration, during one year period. The findings of quantitative content analysis of the news stories regarding Syrian migrant women would provide an understanding of the gender dimension of migration in Turkey. It concludes that Syrian Migrant Women in Turkey generally are reported on crime news and are framed as victims or perpetrators. However, the newspapers rarely report their hard living conditions.

Adriano Santana Fonseca

2000-11-01

Full Text Available CONTEXT: Ewing's sarcoma is a rare neoplasm, which usually arises in long bones of the limbs and in flat bones of the pelvis, with the involvement of head and neck bones being very unusual. CASE REPORT: a case of Ewing's sarcoma occurring in the mandible of a 35-year-old female. Pain and swelling of the tumor were the main complaints. The early hypothesis was an undifferentiated malignant neoplasm, possibly a sarcoma. The CT scan depicted an expansive lesion, encapsulated, with septa and characteristics of soft tissue, involving the left side of the mandible and extending to the surrounding tissues. The patient underwent surgical excision of the lesion, the definitive diagnosis of Ewing's sarcoma was established, and the patient commenced on radiotherapy.

Multiparous Ewe as a Model for Teaching Vaginal Hysterectomy Techniques.

Kerbage, Yohan; Cosson, Michel; Hubert, Thomas; Giraudet, Géraldine

2017-12-01

Despite being linked to improving patient outcomes and limiting costs, the use of vaginal hysterectomy is on the wane. Although a combination of reasons might explain this trend, one cause is a lack of practical training. An appropriate teaching model must therefore be devised. Currently, only low-fidelity simulators exist. Ewes provide an appropriate model for pelvic anatomy and are well-suited for testing vaginal mesh properties. This article sets out a vaginal hysterectomy procedure for use as an education and training model. A multiparous ewe was the model. Surgery was performed under general anesthesia. The ewe was in a lithotomy position resembling that assumed by women on the operating table. Two vaginal hysterectomies were performed on two ewes, following every step precisely as if the model were human. Each surgical step of vaginal hysterectomy performed on the ewe and on a woman were compared side by side. We identified that all surgical steps were particularly similar. The main limitations of this model are costs ($500/procedure), logistic problems (housing large animals), and public opposition to animal training models. The ewe appears to be an appropriate model for teaching and training of vaginal hysterectomy.

The influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system. Changing lifestyles and aging populations are shifting the global disease burden towards increased non-infectious diseases including chronic conditions, co-morbidities, and injuries which are more complicated and costly to manage. The strain placed on health systems threatens the ability to ensure the health needs of both refugees and host country populations are adequately addressed. In light of the increasing challenges facing host governments and humanitarian actors to meet health needs of Syrian refugees and affected host communities, this study was undertaken to assess utilization of health services among Syrian refugees in non-camp settings. A survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households. Differences in household characteristics by geographic region, facility type, and sector utilized were examined using chi-square and t-test methods. Care-seeking was high with 86.1 % of households reporting an adult sought medical care the last time it was needed. Approximately half (51.5 %) of services were sought from public sector facilities, 38.7 % in private facilities, and 9.8 % in charity/NGO facilities. Among adult care seekers, 87.4 % were prescribed medication during the most recent visit, 89.8 % of which obtained the medication. Overall, 51.8 % of households reported out-of-pocket expenditures for the consultation or medications at the most recent visit (mean US$39.9, median US$4.2). Despite high levels of care-seeking, cost was an important barrier to health service access for Syrian refugees in Jordan. The cessation of free access to health care since the time of the survey is likely to have worsened

2009-01-01

Twenty adult ewes were exposed to natural mating by fertile ram labelled on the chest, and marked ewes were separated from the crew. Blood samples were withdrawn from the jugular vein at the intervals 1, 10, 20,112,119,126,133,140 and 147 days after mating. Pregnancy test had been made through determination of progesterone (P4) level by radioimmunoassay. Plasma glucose, cholesterol and total lipids were determined during the last five weeks of pregnancy. Ewes were weighed on mating day and monthly until parturition and the lambs were weighed at birth. Significant difference (P<0.01) in P4 concentration was observed between day of mating and each of 10 and 20 days post-mating. Plasma P4 levels were increased with significant differences between pregnant ewes with single lamb and those with twin lambs at days 10 (P<0.05) and 20 (P<0.01) of pregnancy. The higher P4 level was detected in ewes carrying twins. Plasma P4 levels were increased during late pregnancy followed by a significant decrease (P<0.01) during the last two weeks of pregnancy, in both single and twin bearing ewes. Plasma glucose levels were found to be higher in twin pregnant ewes than single pregnant ewes at week 4 (P<0.05) and week 2 (P<0.01) before parturition. Non-significant differences were observed in plasma cholesterol and total lipids levels between pregnant ewes carrying single and twin lambs during late pregnancy. Monthly body weights were higher in twin than single pregnant ewes. Correlation between ewe and lamb body weights was observed in twin ewes only.

The objective of the study was twofold: (i) to quantify the differences in daily milk yield (DMY) and total milk yield (TMY) between lame and non-lame dairy ewes and (ii) to determine the shape of lactation curves around the lameness incident. The overall study was a prospective study of lameness for the surveyed sheep population, with a nested study including the selection of matching controls for each lame ewe separately. Two intensively reared flocks of purebred Chios ewes and a total of 283 ewes were used. Data, including gait assessment and DMY records, were collected on a weekly basis during on-farm visits across the milking period. A general linear model was developed for the calculation of lactation curves of lame and non-lame ewes, whereas one-way ANOVA was used for the comparisons between lame ewes and their controls. Lameness incidence was 12.4 and 16.8% on Farms A and B, respectively. Average DMY in lame ewes was significantly lower (213.8 g, P ewes was observed during the week 16 of the milking period (P ewes, remained significant at P ewes (about 32.5%), which was maximised 1 week later (35.8%, P ≤ 0.001) and continued for several weeks after recovery, resulting in 19.3% lower TMY for lame ewes for the first 210 d of the milking period (P ewes, as calculated by the general linear model, was 318.9 and 268.0 kg, respectively. The results of this study demonstrate evidence of significant financial losses in dairy sheep due to lameness which, however, need to be accurately estimated in further, more detailed, analyses.

Predicting the duration of the Syrian insurgency

Directory of Open Access Journals (Sweden)

Ulrich Pilster

2014-08-01

Full Text Available While there were several relatively short uprisings in Northern Africa and the Middle East during the Arab Spring, the dispute between the rebels and government forces in Syria has evolved into a full-scale civil war. We try to predict the length of the Syrian insurgency with a three-stage technique. Using out-of-sample techniques, we first assess the predictive capacity of 69 explanatory variables for insurgency duration. After determining the model with the highest predictive power, we categorize Syria according to the variables in this final model. Based on in-sample approaches, we then predict the duration of the Syrian uprising for three different scenarios. The most realistic point prediction is 5.12 years from the insurgency’s start, which suggests an end date between the end of 2016 and early 2017.

Purpose The influx of Syrian refugees into Jordan and Lebanon over the last 5 years presents an immense burden to national health systems. This study was undertaken to assess utilization of maternal health services among Syrian refugees in both countries. Description A cross-sectional survey of Syrian refugees living in urban and rural (non-camp) settings was conducted using a two-stage cluster survey design with probability proportional to size sampling in 2014-2015. Eighty-six percent of surveyed households in Lebanon and 88% of surveyed households in Jordan included women with a live birth in the last year. Information from women in this sub-set of households was analyzed to understand antenatal and intrapartum health service utilization. Assessment A majority of respondents reported seeking antenatal care, 82% and 89% in Jordan and Lebanon, respectively. Women had an average of at least six antenatal care visits. Nearly all births (98% in Jordan and 94% in Lebanon) took place in a health facility. Cesarean rates were similar in both countries; approximately one-third of all births were cesarean deliveries. A substantial proportion of women incurred costs for intrapartum care; 33% of Syrian women in Jordan and 94% of Syrian women in Lebanon reported paying out of pocket for their deliveries. The proportion of women incurring costs for intrapartum care was higher in Jordan both countries for women with cesarean deliveries compared to those with vaginal deliveries; however, this difference was not statistically significant in either country (Jordan p-value = 0.203; Lebanon p-value = 0.099). Conclusion Syrian refugees living in Jordan and Lebanon had similar levels of utilization of maternal health services, despite different health systems and humanitarian assistance provisions. As expected, a substantial proportion of households incurred out-of-pocket costs for essential maternal and newborn health services, making cost a major factor in care

The influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system, particularly in treating chronic health conditions. This study was undertaken to assess utilization of health services for chronic health conditions among Syrian refugees in non-camp settings. A survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care for hypertension, diabetes, cardiovascular diseases, chronic respiratory diseases, and arthritis. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households. Of 1363 cases with a chronic health condition diagnosis, 84.7% had received care in Jordan. Public facilities faced a heavy burden serving over half (53.9%) of care-seekers; the remainder received care in the private (29.6%) and NGO/charity (16.6%) sectors. Individuals with non-communicable diseases (NCDs) in the central region of Jordan and with arthritis had the lowest rates of care-seeking when compared to other regions and conditions. Overall, 31.6% of care-seekers had an out-of-pocket payment for the most recent care-seeking event which averaged 18.8 USD (median = 0 USD), excluding cost of medications. Forced displacement presents major challenges to those with NCDs, which have the potential to seriously impact both the quality of life and life expectancy amongst refugees. NCD patterns among Syrian refugees indicate the importance of continuing support to public sector services in Jordan to adequately meet expanding needs and ensure appropriate prevention and control of priority NCDs.

Syrian Refugees, Health and Migration Legislation in Turkey.

Science.gov (United States)

Ekmekci, Perihan Elif

2017-12-01

This paper discusses the crucial effects of Turkish health and migration laws on Syrian refugees' access to public health services and social determinants of health. Key aspects of current Turkish laws affect the health of both refugees and Turkish citizens in many ways. The huge influx of refugees is increasing communicable disease risks, overcrowding hospitals, and more generally straining financial and health resources. Turkey's United Nations membership and its candidacy for European Union (EU) have led to increased alignment of Turkey's refugee and migration policies with international law. Major differences remain, however, and Turkey's remaining noncompliance with international refugee laws is a major force driving Syrian refugee's flight to EU countries, as refugees desperately seek the right to better health and social services.

The qualitative histological alterations of ovaries and caryometric changes in the corpora lutea (CL) were studied in the ewes of the Slovak Merino breed after irradiation with X-rays. The experiments were conducted on 12 ewes divided into three groups of four animals. The first group included the control ewes, the second, experimental group was exposed to X-rays applied directly to the ovaries after laparotomy at a rate of 64.4 mC per kg (250 R), and the ewes in the third group were locally irradiated in the hypothalamo-hypophysial region at a rate of 516.5 mC per kg (2000 R). On the 10th day following the irradiation, the animals were killed, ovarian excisions were taken from the carcasses and processed. Changes in the blood vessels of the ovaries of the ewes in the second group were revealed by qualitative microscopic analysis. Pronounced subintimal changes, reminding of foamy cells described in available literature as a consequence of radiation damage to the blood vessels, were observed in the arteries and veins of the marrow and porta of the ovaries. A pronounced alteration of follicular structures was induced by single local irradiation of the ovaries which, at the same time, stimulated CL production. The irradiation of the hypothalamo-hypophysial region resulted in a multiplication of normal tertiary follicles and in an increase of the total number of follicles. No other histological changes were observed in the tissues of ovaries after irradiation of the hypothalamo-hypophysial region

A Content Analysis on the Representation of Syrian Asylum Seekers in the Turkish Press

Directory of Open Access Journals (Sweden)

Müzeyyen Pandır

2015-11-01

Full Text Available This article is a content analysis of the representation of Syrian asylum seekers in the Turkish press. The research sample includes news reports, columns and visuals published in 2014 in five national newspapers with the highest circulation figures (“Hürriyet”, “Sabah”, “Posta”, “Sözcü”, “Zaman”. The article is part of a larger research project, which is funded by TÜBİTAK, investigating the representation of Syrian asylum seekers between 2011 and 2015 in Turkish newspapers. Analysing news texts and columns is widely held in research projects. However, conducting a visual analysis on news photographs is usually overlooked. This study investigates news texts and news photographs together. The study shows that the coverage of Syrian asylum seekers has usually a positive or neutral content. However, the results also point out the ambivalence in the representations of asylum seekers. The representations of Syrian asylum seekers portray these individuals mostly as “poor” people “in need of help” as well as “threats” for social security. These frequently repeated representations and ambivalence show that the representation of Syrian asylum seekers in Turkish newspapers reproduces the stereotypical representation of asylum seekers as defined in international studies.

Ewing's sarcomas are aggressive musculoskeletal tumors occurring most frequently in the long and flat bones as a solitary lesion mostly during the teen-age years of life. With current treatments, significant number of patients relapse and survival is poor for those with metastatic disease. As part of novel target discovery in Ewing's sarcoma, we applied RNAi mediated phenotypic profiling to identify kinase targets involved in growth and survival of Ewing's sarcoma cells. Four Ewing's sarcoma cell lines TC-32, TC-71, SK-ES-1 and RD-ES were tested in high throughput-RNAi screens using a siRNA library targeting 572 kinases. Knockdown of 25 siRNAs reduced the growth of all four Ewing's sarcoma cell lines in replicate screens. Of these, 16 siRNA were specific and reduced proliferation of Ewing's sarcoma cells as compared to normal fibroblasts. Secondary validation and preliminary mechanistic studies highlighted the kinases STK10 and TNK2 as having important roles in growth and survival of Ewing's sarcoma cells. Furthermore, knockdown of STK10 and TNK2 by siRNA showed increased apoptosis. In summary, RNAi-based phenotypic profiling proved to be a powerful gene target discovery strategy, leading to successful identification and validation of STK10 and TNK2 as two novel potential therapeutic targets for Ewing's sarcoma.

In rodents, progesterone (P4) pretreatment increases anxiety and response to stressors. Social isolation is a stressor that generates physiological and behavioural stress responses in sheep. The aim of the study was to compare the stress response of anoestrous ewes previously treated or not with P4 to the social isolation test. Ten ewes received P4 treatment during 13 d (group P4-W) and another 10 remained untreated as controls (group Con). The ewes were individually isolated in a novel place during 10 min, 24 h after the end of P4 pretreatment and their behaviours were recorded. Cortisol and P4 concentrations as well as body surface temperature were recorded before and after the test. Ewes of the P4-W group presented higher cortisol levels 0, 10, 20 and 30 min after the social isolation and had greater area under the curve of cortisol compared to Con ewes (41,785%±4,156% vs. 25,682%±4,565% during 75 min). Progesterone and body surface temperature increased after social isolation, with no differences between P4-W and Con ewes. There were no differences in behavioural responses to social isolation. P4 pretreatment appears to augment the stress response to social isolation in anoestrous ewes.

Impact of the Syrian refugee crisis on land use and transboundary freshwater resources.

Since 2013, hundreds of thousands of refugees have migrated southward to Jordan to escape the Syrian civil war that began in mid-2011. Evaluating impacts of conflict and migration on land use and transboundary water resources in an active war zone remains a challenge. However, spatial and statistical analyses of satellite imagery for the recent period of Syrian refugee mass migration provide evidence of rapid changes in land use, water use, and water management in the Yarmouk-Jordan river watershed shared by Syria, Jordan, and Israel. Conflict and consequent migration caused ∼50% decreases in both irrigated agriculture in Syria and retention of winter rainfall in Syrian dams, which gave rise to unexpected additional stream flow to downstream Jordan during the refugee migration period. Comparing premigration and postmigration periods, Syrian abandonment of irrigated agriculture accounts for half of the stream flow increase, with the other half attributable to recovery from a severe drought. Despite this increase, the Yarmouk River flow into Jordan is still substantially below the volume that was expected by Jordan under the 1953, 1987, and 2001 bilateral agreements with Syria.

Cyclin D1 and Ewing's sarcoma/PNET: A microarray analysis.

Fagone, Paolo; Nicoletti, Ferdinando; Salvatorelli, Lucia; Musumeci, Giuseppe; Magro, Gaetano

2015-10-01

Recent immunohistochemical analyses have showed that cyclin D1 is expressed in soft tissue Ewing's sarcoma/peripheral neuroectodermal tumor (PNET) of childhood and adolescents, while it is undetectable in both embryonal and alveolar rhabdomyosarcoma. In the present paper, microarray analysis provided evidence of a significant upregulation of cyclin D1 in Ewing's sarcoma as compared to normal tissues. In addition, we confirmed our previous findings of a significant over-expression of cyclin D1 in Ewing sarcoma as compared to rhabdomyosarcoma. Bioinformatic analysis also allowed to identify some other genes, strongly correlated to cyclin D1, which, although not previously studied in pediatric tumors, could represent novel markers for the diagnosis and prognosis of Ewing's sarcoma/PNET. The data herein provided support not only the use of cyclin D1 as a diagnostic marker of Ewing sarcoma/PNET but also the possibility of using drugs targeting cyclin D1 as potential therapeutic strategies.

Background. Ewing's sarcoma of extraskeletal origin is uncommon and that is of primary renal origin in adults are rare. There is no consensus on the optimal management of Ewing's tumors of renal origin. Methods. A retrospective review of the clinical features, treatment, and outcome of adult patients with primary renal extra-skeletal Ewing's sarcoma who were treated at the Royal Marsden hospital from January 1993–December 2007 is reported. Results. Seven adult patients with primary renal Ewing's sarcoma were identified. All four patients with nonmetastatic disease had radical nephrectomy and received adjuvant chemotherapy +/− radiotherapy. Two developed metastatic disease while on adjuvant chemotherapy, and one patient relapsed after 55 months. The three patients with metastatic disease at presentation did not have nephrectomy and were treated with chemotherapy. All three patients had disease progression with a dismal outcome. Only one patient in the whole group is alive and disease free. The median overall survival was 62.8 months, and the median disease-free survival in patients with nonmetastatic disease after combined modality treatment was 30.3 months. Conclusion. Primary adult renal Ewing's sarcoma is an aggressive tumor with a propensity for early metastasis. Radical nephrectomy with adjuvant combination chemotherapy produced the best results but the outlook remained poor with only one patient experiencing long disease-free survival. PMID:19478963

This study was conducted with an ovine intrauterine growth restriction (IUGR) model to test the hypothesis that dietary -carbamylglutamate (NCG) and rumen-protected -Arg (RP-Arg) supplementation are effective in ameliorating fetal growth restriction in undernourished ewes. Beginning on d 35 of gestation, ewes were fed a diet providing 100% of NRC-recommended nutrient requirements, 50% of NRC recommendations (50% NRC), 50% of NRC recommendations supplemented with 20 g/d RP-Arg (providing 10 g/d of Arg), and 50% of NRC recommendations supplemented with 5 g/d NCG product (providing 2.5 g/d of NCG). On d 110, maternal, fetal, and placental tissues and fluids were collected and weighed. Ewe weights were lower ( ewes compared with adequately fed ewes. Maternal RP-Arg or NCG supplementation did not alter ( = 0.26) maternal BW in nutrient-restricted ewes. Weights of most fetal organs were increased ( ewes compared with 50% NRC-fed ewes. Supplementation of RP-Arg or NCG reduced ( ewes but had no effect on concentrations of lactate and GH. Maternal RP-Arg or NCG supplementation markedly improved ( ewes. These novel results indicate that dietary NCG and RP-Arg supplementation to underfed ewes ameliorated fetal growth restriction, at least in part, by increasing the availability of AA in the conceptus and provide support for its clinical use to ameliorate IUGR in humans and sheep industry production.

Ewing's sarcoma classically presents as a hot spot on bone scan as a result of increased vascularity of the tumor and new bone formation. Purpose We report and analyze an uncommon pattern of a 'cold' lesion in Ewing's sarcoma on bone scan and its pathophysiologic significance. Case report A 15-year-old boy complaining of thigh pain. CT scan evoked Ewing's sarcoma or osteitis. MRI evoked chronic osteitis. Scintigraphy showed a fairly intense and heterogeneous uptake on the femoral lesion and no abnormal uptake elsewhere. Biopsy showed none pathologic pattern. Three months later, a second biopsy concluded to Ewing's sarcoma. Bone scan showed a larger lesion with peripheral intense uptake centered by enlarged 'cold' area in the left femoral diaphysis and no evident bone metastasis. The patient underwent chemotherapy and surgery. Three months later, bone scan showed extensive skeletal metastasis. Conclusion Ewing's sarcoma appears usually as an intense lesion on bone scan. Nevertheless, decreased radiopharmaceutical uptake or 'cold' lesion may be seen in aggressive Ewing's sarcoma with lytic tumor, growth of which is very rapid and bony reaction is minimal. (authors)

The Syrian War has created a mass exodus of Syrian citizens to neighboring countries and exposed them to many atrocities. We explored factors affecting well-being and posttraumatic growth (PTG) of refugees residing in Jordan. Participants (N = 250) were surveyed via nongovernmental organizations (NGOs). Outcome criteria included a global well-being rating and the Posttraumatic Growth Inventory. Trauma exposure assessment included The Harvard Trauma Questionnaire (HTQ) and The War Events Questionnaire. Ordinary least squares regression examined associations between potential contributors to refugee well-being and PTG, including work, age, sex, income, education, posttraumatic stress disorder (PTSD) severity, physical pain, health, NGO assistance, psychotic/affective mental disorder, and length of residence in Jordan. Mean participant score on the PTSD-HTQ scale was 2.37 (SD = 0.63; range: 1 [no symptoms] to 3.88 [extremely severe symptoms]). Additionally, 74.6% of participants received NGO assistance and 92.7% experienced war events. Univariate and multivariate results indicated enhancement of well-being was associated with income, r = .34, β = .26, p Syrian refugees' mental health.

2017-06-01

Full Text Available As of March 2016, 4.8 million Syrian refugees were scattered in two dozen countries by the civil war. Refugee smuggling has been a major catalyst of human trafficking in the Middle East and Europe migrant crises. Data on the extent to which smuggling devolved into trafficking in this refugee wave is, however, scarce. This article investigates how Syrian refugees interact with smugglers, shedding light on how human smuggling and human trafficking interrelated on the Balkan Route. I rely on original evidence from in-depth interviews (n = 123 and surveys (n = 100 with Syrian refugees in Jordan, Turkey, Greece, Serbia, and Germany; as well as ethnographic observations in thirty-five refugee camps or other sites in these countries. I argue that most smugglers functioned as guides, informants, and allies in understudied ways—thus refugee perceptions diverge dramatically from government policy assumptions. I conclude with a recommendation for a targeted advice policy that would acknowledge the reality of migrant-smuggler relations, and more effectively curb trafficking instead of endangering refugees.

Hair sheep ewes (St. Croix White and Barbados Blackbelly) were used to evaluate 3 methods of estrus synchronization for use with transcervical artificial insemination (TAI). To synchronize estrus, ewes (n = 18) were treated with PGF2alpha (15 mg, im) 10 d apart, with controlled internal drug release (CIDR) devices containing 300 mg progesterone for 12 d (n = 18), or with intravaginal sponges containing 500 mg progesterone for 12 d (n = 18). On the day of the second PGF2alpha injection or at CIDR or sponge removal, sterile rams were placed with the ewes. Jugular blood samples were collected from the ewes at 6-h intervals until the time of ovulation, and daily for 16 d after estrus (Day 0). Plasma was harvested and stored at -20 degrees C until LH, and progesterone concentrations were determined by RIA. There was no difference (P>0.10) in time to estrus among the CIDR-, PGF2alpha- or sponge-treated ewes. All of the ewes in the CIDR group and 94.4% of the sponge treated ewes exhibited estrus by 36 h after ram introduction, while only 72.2% of PGF2alpha-treated ewes showed signs of estrus by this time (P0.10) among the CIDR-, PGF2alpha- or sponge-treated ewes. The time to the preovulatory LH surge was similar (P>0.10) among CIDR, PGF2alpha and sponge treated ewes. Progesterone levels through Day 16 after the synchronized estrus were not different (P>0.10) among treatment groups. Hair sheep ewes (n = 23) were synchronized using PGF2alpha and bred by TAI using frozen-thawed semen 48 h after the second injection. The conception rate to TAI was 2/23 (8.7%) and produced 3 ram lambs. In a subsequent trial, 17 ewes were synchronized with CIDR devices and bred by TAI using frozen-thawed semen 48 h after CIDR removal, resulting in a conception rate of 52.9% (9/17). It is possible to synchronize estrus in hair sheep using either CIDRs, sponges or PGF2alpha. Even though there were no significant differences in the timing of ovulation or the LH surge among the treatment groups, a

The first ovulation induced by male effect in sheep during seasonal anoestrus usually results in the development of a short cycle that can be avoided by progesterone priming before ram introduction. In elucidating the involvement of the hypothalamic-pituitary-gonadal axis in the occurrence of short cycles, the effects of progesterone and the time of anoestrus on the development of male-induced preovulatory follicles were investigated in anoestrous ewes using morphological, endocrine and molecular approaches. Ewes were primed with progesterone for 2 (CIDR2) or 12 days (CIDR12) and untreated ewes used as controls during early (April) and late (June) anoestrus. The duration of follicular growth and the lifespan of the male-induced preovulatory follicles were prolonged by ∼1.6 days in CIDR12 ewes compared with the controls. These changes were accompanied by a delay in the preovulatory LH and FSH surges and ovulation. Intra-follicular oestradiol concentration and mRNA levels of LHCGR and STAR in the granulosa and theca cells of the preovulatory follicles were higher in CIDR12 ewes than the control ewes. The expression of mRNA levels of CYP11A1 and CYP17A1 also increased in theca cells of CIDR12 ewes. CIDR2 ewes gave intermediate results. Moreover, ewes ovulated earlier in June than in April, without changes in the duration of follicular growth, but these effects were unrelated to the lifespan of corpus luteum. Our results give the first evidence supporting the positive effect of progesterone priming on the completion of growth and maturation of preovulatory follicles induced by male effect in seasonal anoestrous ewes, thereby preventing short cycles. © 2014 Society for Reproduction and Fertility.

Ewing's sarcoma is a highly aggressive malignant tumour most commonly affecting long bones in children and adolescents. It is part of the Ewing's sarcoma family of tumours (ESFTs) that also include peripheral primitive neuroectodermal tumour and Askin's tumours. ESFTs share common cytogenetic aberrations, antigenic profiles and proto-oncogene expression with an overall similar clinical course. In 99% of ESFTs, genetic translocation with molecular fusion involves the EWSR1 gene on 22q12. Approximately 30% of ESFTs are extraosseous, most commonly occurring in the soft tissues of extremities, pelvis, retroperitoneum and chest wall. Primary presentation in solid organs is very rare but has been described in multiple sites including the pancreas. Accurate diagnosis of a Ewing's sarcoma in a solid organ is critical in facilitating correct treatment. We report the case of a 17-year-old girl with cytogenetically confirmed primary pancreatic Ewing's sarcoma and provide a brief review of the published literature. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Full Text Available The influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system, particularly in treating chronic health conditions. This study was undertaken to assess utilization of health services for chronic health conditions among Syrian refugees in non-camp settings.A survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care for hypertension, diabetes, cardiovascular diseases, chronic respiratory diseases, and arthritis. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households.Of 1363 cases with a chronic health condition diagnosis, 84.7% had received care in Jordan. Public facilities faced a heavy burden serving over half (53.9% of care-seekers; the remainder received care in the private (29.6% and NGO/charity (16.6% sectors. Individuals with non-communicable diseases (NCDs in the central region of Jordan and with arthritis had the lowest rates of care-seeking when compared to other regions and conditions. Overall, 31.6% of care-seekers had an out-of-pocket payment for the most recent care-seeking event which averaged 18.8 USD (median = 0 USD, excluding cost of medications.Forced displacement presents major challenges to those with NCDs, which have the potential to seriously impact both the quality of life and life expectancy amongst refugees. NCD patterns among Syrian refugees indicate the importance of continuing support to public sector services in Jordan to adequately meet expanding needs and ensure appropriate prevention and control of priority NCDs.

Microsatellites with Macro-Influence in Ewing Sarcoma

Directory of Open Access Journals (Sweden)

Stephen L. Lessnick

2012-07-01

Full Text Available Numerous molecular abnormalities contribute to the genetic derangements involved in tumorigenesis. Chromosomal translocations are a frequent source of these derangements, producing unique fusion proteins with novel oncogenic properties. EWS/ETS fusions in Ewing sarcoma are a prime example of this, resulting in potent chimeric oncoproteins with novel biological properties and a unique transcriptional signature essential for oncogenesis. Recent evidence demonstrates that EWS/FLI, the most common EWS/ETS fusion in Ewing sarcoma, upregulates gene expression using a GGAA microsatellite response element dispersed throughout the human genome. These GGAA microsatellites function as enhancer elements, are sites of epigenetic regulation and are necessary for EWS/FLI DNA binding and upregulation of principal oncogenic targets. An increasing number of GGAA motifs appear to substantially enhance EWS/FLI-mediated gene expression, which has compelling biological implications as these GGAA microsatellites are highly polymorphic within and between ethnically distinct populations. Historically regarded as junk DNA, this emerging evidence clearly demonstrates that microsatellite DNA plays an instrumental role in EWS/FLI-mediated transcriptional regulation and oncogenesis in Ewing sarcoma. This unprecedented role of GGAA microsatellite DNA in Ewing sarcoma provides a unique opportunity to expand our mechanistic understanding of how EWS/ETS fusions influence cancer susceptibility, prognosis and transcriptional regulation.

Although fixed-time artificial insemination (FTAI) protocols are available for sheep, estrus resynchronization has not been previously reported. The objectives of this study were to evaluate the effect of estrus resynchronization with exogenous progestogen on endogenous progesterone levels and to compare pregnancy rates after two consecutive estrus synchronizations in ewes. In Experiment 1, ewes (n = 20) received an intravaginal device (IVD) containing 60 mg medroxyprogesterone acetate (MPA) for 10 days. At the IVD withdrawal (D0), ewes received 250 IU eCG and were allocated into two treatments: either no further treatment (Control; n = 10) or estrus resynchronization (Resynch; n = 10) from D12 to D19. Serum progesterone (P4) levels did not differ at D12 and D19 (P > 0.05), but were greater at D15 for the Control compared with the Resynch group (P ewes (n = 250) were submitted to a first synchronization protocol followed by estrus detection and either artificial insemination (AI) or natural mating (NM). Subsequently, ewes were divided into two groups: Control (n = 104): which received no further treatment and were bred by NM; and Resynch (n = 146): which were submitted to a second synchronization starting on D14 (first IVD withdrawal = D0) and to NM after second IVD withdrawal (D20). Cumulative pregnancy rates did not differ between the Control (67.3%, 70/104) and Resynch (62.3%, 91/146) groups. In a third experiment, ewes (n = 83) were bred by two consecutive FTAI within a 20-day interval. Pregnancy rates after the first (30.1%, 25/83) and the second FTAI (36.2%, 21/58) did not differ (P > 0.05). In conclusion, although exogenous progestogen supplementation reduced circulating levels of P4, pregnancy maintenance was unaffected. Estrus resynchronization in ewes is feasible, resulting in similar fertility after the first and the second services.

2013-01-01

The present study was aimed at investigating the effect of experimental infection by Trypanosoma vivax in different stages of pregnancy, determining the pathogenesis of reproductive failure, and confirming transplacental transmission. We used 12 pregnant ewes distributed into four experimental groups: G1, was formed by three ewes infected with T. vivax in the first third of pregnancy (30 days); G2 comprised three infected ewes in the final third of pregnancy (100 days); G3 and G4 were composed of three non-infected ewes with the same gestational period, respectively. Each ewe of G1 and G2 was inoculated with 1.25 × 105 tripomastigotes. Clinical examination, determination of parasitemia, serum biochemistry (albumin, total protein, glucose, cholesterol, and urea), packed cell volume (PCV), serum progesterone, and pathological examination were performed. Placenta, amniotic fluid, blood and tissues from the fetuses and stillbirths were submitted to PCR. Two ewes of G1 (Ewe 1 and 3) presented severe infection and died in the 34th and 35th days post-infection (dpi), respectively; but both fetuses were recovered during necropsy. In G2, Ewe 5 aborted two fetuses on the 130th day (30 dpi) of pregnancy; and Ewe 6 aborted one fetus in the 140th day (40 dpi) of gestation. Ewes 2 and 4 delivered two weak lambs that died five days after birth. Factors possibly involved with the reproductive failure included high parasitemia, fever, low PCV, body score, serum glucose, total protein, cholesterol, and progesterone. Hepatitis, pericarditis, and encephalitis were observed in the aborted fetuses. The presence of T. vivax DNA in the placenta, amniotic fluid, blood, and tissues from the fetuses confirms the transplacental transmission of the parasite. Histological lesion in the fetuses and placenta also suggest the involvement of the parasite in the etiopathogenesis of reproductive failure in ewes. PMID:23289625

The use of intravaginal sponges (IS) to synchronize estrous onset in ewes provokes vaginitis, an increase in the vaginal bacterial load, and growth of bacterial species that are not present during spontaneous estrous behavior. The objective of the study was to compare the functional sperm parameters after incubating it with mucus collected from the vagina of ewes during spontaneous estrus or estrous synchronized with IS. Pooled spermatozoa were co-incubated with: (1) vaginal mucus collected from ewes in spontaneous estrus; (2) vaginal mucus collected from ewes in estrus pretreated with progestogen-impregnated IS; (3) synthetic mucus; and (4) medium without mucus as a control group. Sperm samples were evaluated after incubating it for 30 and 90 minutes. The number of colony-forming units (CFUs/mL), pH, and osmolality were greater in the mucus collected from ewes treated with IS than from those untreated (P = 0.046; P ewes treated with IS than in the other three treatments both, 30 and 90 minutes after incubation (P = 0.0009 and P ewes treated with IS had a lower percentage of sperm with intact plasma membrane than all the other treatments (P ewes treated with IS than in the other three treatments (P ewes during their spontaneous estrus (P = 0.0005). The lowest percentages of sperm with acrosome damage were observed in sperm incubated with mucus collected from sheep in spontaneous estrus for 30 and 90 minutes (P ewes treated with IS than in the other three groups (P = 0.0005). The functionality and the viability of ram sperm is negatively affected by the cervical mucus of ewes pretreated with progestagen-impregnated IS used in estrous synchronization treatments. This may partially explain the decrease in conception rate obtained with treatments with IS. Copyright © 2016 Elsevier Inc. All rights reserved.

William B. Coley developed bacterial therapy of cancer more than 100 years ago and had clinical success. James Ewing, a very famous cancer pathologist for whom the Ewing sarcoma is named, was Coley's boss at Memorial Hospital in New York and terminated Coley's bacterial therapy of cancer. A tumor from a patient with soft-tissue Ewing's sarcoma, who failed doxorubicin (DOX) therapy, was previously implanted in nude mice to establish a patient-derived orthotopic xenograft (PDOX) model. In the present study, the Ewing's sarcoma PDOX was treated with tumor-targeting S. typhimurium A1-R expressing green fluorescent (GFP), alone and in combination with DOX. S. typhimurium A1-R-GFP was detected in the tumors after intratumor (i.t.) or intravenous (i.v.) injection. The combination of S. typhimurium A1-R and DOX significantly reduced tumor weight (37.8 ± 15.6 mg) compared to the untreated control (73.8 ± 10.1 mg, P Ewing's sarcoma had in the patient. S. typhimurium A1-R converted the Ewing's sarcoma from DOX resistant to sensitive. One can only wonder how bacterial therapy and immunotherapy of cancer would have developed over the past 80 years if Ewing did not stop Coley.

Full Text Available The conflict in Syria between the government of Bashar al-Assad and various other forces, which started in the spring of 2011, continues to cause displacement within the country and across the region. By the end of 2014, an estimated 7.6 million people were internally displaced and 3.7 million Syrians had fled the country since the conflict began (OCHA 2014; UNHCR 2015a. The refugee situation caused by the Syrian conflict is dire, and it has placed enormous strain on neighboring countries. Lebanon, Jordan, Iraq, Egypt, and Turkey host massive numbers of Syrian refugees, and Syrians have been seeking protection beyond these countries in increasing numbers since 2011.This paper looks at the burdens and costs of the Syrian refugee crisis and considers how they have, or have not, been shared by the international community at large, and in particular by Germany, Sweden, the United Kingdom, and the United States. It also considers to what degree Syrians have been able to find protection in states outside the region. Germany and Sweden, by the end of 2014, had provided protection to the largest number of Syrian refugees outside the region. Although Germany, Sweden, the United Kingdom, and the United States differ in the level of protection provided to Syrians, all four states have increased protection to Syrians via resettlement and asylum (and in the case of the US temporary protected status since 2012. Despite this, the degree of protection provided by the four states is modest in relation to that provided by neighboring countries to Syria, and far more could be done. This paper also argues that the international community as a whole has not sufficiently contributed toward alleviating the burden caused by the Syrian refugee influx, in terms of both financial assistance and refugee resettlement.The paper puts forward two general recommendations to reduce the strain on neighboring countries: increase the level of burden sharing by the international

Background and purpose: Radiotherapy constitutes an essential element in the multimodal therapy of Ewing's sarcoma. Compared to other sarcomas, Ewing tumors normally show a good response to radiotherapy. However, there are consistently tumors with a radioresistant phenotype, and the underlying mechanisms are not known in detail. Here we investigated the association between survivin protein expression and the radiosensitivity of Ewing's sarcoma in vitro. Material and methods: An siRNA-based knockdown approach was used to investigate the influence of survivin expression on cell proliferation, double-strand break (DSB) induction and repair, apoptosis and colony-forming ability in four Ewing's sarcoma cell lines with and without irradiation. Results: Survivin protein and mRNA were upregulated in all cell lines tested in a dose-dependent manner. As a result of survivin knockdown, STA-ET-1 cells showed reduced cell proliferation, an increased number of radiation-induced DSBs, and reduced repair. Apoptosis was increased by knockdown alone and increased further in combination with irradiation. Colony formation was significantly reduced by survivin knockdown in combination with irradiation. Conclusion: Survivin is a radiation-inducible protein in Ewing's sarcoma and its down-regulation sensitizes cells toward irradiation. Survivin knockdown in combination with radiation inhibits cell proliferation, repair, and colony formation significantly and increases apoptosis more than each single treatment alone. This might open new perspectives in the radiation treatment of Ewing's sarcoma. (orig.)

Full Text Available Considering the facts that Istrian sheep is Croatian indigenous breed with the highest milk production, and increasing interest of local farmers for machine milking implementation, the aim of this study was to determine the factors affecting udder morphology traits of Istrian ewes. Ninetythree purebred Istrian ewes with symmetrical udders and no signs of clinical mastitis, from second to fourth lactation, were used for this study. Average udder depth of Istrian ewes was 15.85 cm, udder width 13.05 cm, udder circumference 39.66 cm, cistern height 1.44 cm, teat position 2.85 (scored from 1 to 5, teat angle 47.32°, teat length 3.43 cm and teat width 2.03 cm. The traits related to udder size (depth, width, and circumference were significantly (P<0.01 affected by lactation milk yield. These traits were also in high and positive correlations (P<0.01 with daily milk yield. With the increase of parity, the morphological aptitude of udder to mechanical milking become worse, with an increase (P<0.01 of cistern height, teat angle and position. As lactation of Istrian ewes continued morphological traits defining udder aptitude for machine milking improved (decrease of cistern height, teat angle and position. Ewes with two and more lambs had larger udder (P<0.05 than ewes with a single lamb.

Since 2013, hundreds of thousands of refugees have migrated southward to Jordan to escape the Syrian civil war that began in mid-2011. Evaluating impacts of conflict and migration on land use and transboundary water resources in an active war zone remains a challenge. However, spatial and statistical analyses of satellite imagery for the recent period of Syrian refugee mass migration provide evidence of rapid changes in land use, water use, and water management in the Yarmouk–Jordan river watershed shared by Syria, Jordan, and Israel. Conflict and consequent migration caused ∼50% decreases in both irrigated agriculture in Syria and retention of winter rainfall in Syrian dams, which gave rise to unexpected additional stream flow to downstream Jordan during the refugee migration period. Comparing premigration and postmigration periods, Syrian abandonment of irrigated agriculture accounts for half of the stream flow increase, with the other half attributable to recovery from a severe drought. Despite this increase, the Yarmouk River flow into Jordan is still substantially below the volume that was expected by Jordan under the 1953, 1987, and 2001 bilateral agreements with Syria.

Challet, E; Kolker, D E; Turek, F W

Calorie restriction and other situations of reduced glucose availability in rodents alter the entraining effects of light on the circadian pacemaker located in the suprachiasmatic nuclei. Siberian and Syrian hamsters are photoperiodic species that are sexually active when exposed to long summer-like photoperiods, while both species show opposite changes in body mass when transferred from long to short or short to long days. Because metabolic cues may fine tune the photoperiodic responses via the suprachiasmatic nuclei, we tested whether timed calorie restriction can alter the photic synchronization of the light-entrainable pacemaker in these two hamster species exposed to long photoperiods. Siberian and Syrian hamsters were exposed to 16 h:8 h light:dark cycles and received daily hypocaloric (75% of daily food intake) or normocaloric diet (100% of daily food intake) 4 h after light onset. Four weeks later, hamsters were transferred to constant darkness and fed ad libitum. The onset of the nocturnal pattern of locomotor activity was phase advanced by 1.5 h in calorie-restricted Siberian hamsters, but not in Syrian hamsters. The lack of phase change in calorie-restricted Syrian hamsters was also observed in individuals exposed to 14 h:10 h dim light:dark cycles and fed with lower hypocaloric food (i.e. 60% of daily food intake) 2 h after light onset. Moreover, in hamsters housed in constant darkness and fed ad lib., light-induced phase shifts of the locomotor activity in Siberian hamsters, but not in Syrian hamsters were significantly reduced when glucose utilization was blocked by pretreatment with 500 mg/kg i.p. 2-deoxy-D-glucose. Taken together, these results show that the photic synchronization of the light-entrainable pacemaker can be modulated by metabolic cues in Siberian hamsters, but not in Syrian hamsters maintained on long days.

Extraskeletal Ewing's sarcoma is a rare malignant soft tissue tumor, classified within the Ewing's Sarcoma Family Tumors. While the classical Ewing's Sarcoma affects mainly the bone during youth, the Extraskeletal histotype differs for age incidence, primary location and prognosis. Peak incidence and typical location are during adolescence and in the extremities respectively. We report a 30 year old woman case with a positive outcome after ten years from first diagnosis of Extraskeletal Ewing's sarcoma. Treatment was achieved through surgical resection plus adjuvant chemoradiotherapy derived from EW93 and IRS III trials. Conclusion. Our report represents an unusual case due to age of presentation, neoplasm location and long survival reached. In last decades several trials results demonstrated that long survival could be achieved by combined surgery and adjuvant multi-drug treatment.

Mesenchymal Stem Cells and the Origin of Ewing's Sarcoma

Full Text Available The origin of Ewing's sarcoma is a subject of much debate. Once thought to be derived from primitive neuroectodermal cells, many now believe it to arise from a mesenchymal stem cell (MSC. Expression of the EWS-FLI1 fusion gene in MSCs changes cell morphology to resemble Ewing's sarcoma and induces expression of neuroectodermal markers. In murine cells, transformation to sarcomas can occur. In knockdown experiments, Ewing's sarcoma cells develop characteristics of MSCs and the ability to differentiate into mesodermal lineages. However, it cannot be concluded that MSCs are the cell of origin. The concept of an MSC still needs to be rigorously defined, and there may be different subpopulations of mesenchymal pluripotential cells. Furthermore, EWS-FLI1 by itself does not transform human cells, and cooperating mutations appear to be necessary. Therefore, while it is possible that Ewing's sarcoma may originate from a primitive mesenchymal cell, the idea needs to be refined further.

Ewing's sarcoma is a round cell neoplasm derived from neural crest cells that is part of the primitive neuroectodermal tumor (PNET) family. It is a rare, aggressive malignancy that affects young people, most commonly in the second decade of life. The treatment of localized disease has improved greatly over the past four decades, but the prognosis for metastatic disease remains poor. Cardiac metastases of Ewing's sarcoma are exceedingly rare, with only a few reported cases. This...

Humanitarian organisations supporting Syrian refugees in Jordan have conducted needs assessments to direct resources appropriately. To present a model of psychosocial concerns reported by Syrian refugees and a peer review of research practices. Academic and grey literature databases, the United Nations Syria Regional Response website, key humanitarian organisation websites and Google were searched for needs assessments with Syrian refugees in Jordan between February 2011 and June 2015. Information directly reporting the views of Syrian refugees regarding psychosocial needs was extracted and a qualitative synthesis was conducted. Respondents reported that psychological distress was exacerbated by both environmental (financial, housing, employment) and psychosocial outcomes (loss of role and social support, inactivity), which are themselves stressors. Need for improvement in research methodology, participatory engagement and ethical reporting was evident. Participatory engagement strategies might help to address identified psychosocial outcomes. More rigorous qualitative methods are required to ensure accuracy of findings. © The Royal College of Psychiatrists 2016.

Inventories and fluxes of 137Cs in the Syrian land

Cesium-137 inventories and atmospheric fluxes have been determined using radiocesium distributions in undistributed soil profiles, collected from 38 sites distributed all over the Syrian lands. Results have shown that 137 Cs inventories determination by Soil Layers Sum Method is more accurate than the Integration Method, where the best curve fitting of 137 Cs distribution with depth is difficult to establish. 137 Cs inventories ranged from 441 Bq.m - 2 and 13312 Bq.m - 2 using the Layers Sum Method with a mean value of 3679 Bq.m - 2; the highest values observed were in the coastal, middle and north east regions. This is due to the fact that most of Chernobyl accident atmospheric fall-out of cesium 137 had entered the Syrian land came from the west boarders (Mediterranean sea). While the lowest values were found to be in the samples collected from the east south region. In addition, 137 Cs flux ranged from 3.1 kBq m - 2y - 1 and 527.8 kBq m - 2 y - 1 with a mean value of 65.7 kBq m - 2y - 1. Moreover, there was a semi linear relationship found between 137 Cs flux and the height above sea level. While no linear relationship was found between 137 Cs flux and annual rainfall. On the other hand, the external radiation dose to Syrians that due to gamma-rays emitted from cesium 137 decay has been determined and reached a mean value of 166μ Sv.y - 1. This value is about 20% of the radiation dose received by the Syrian from naturally occurring radionuclides in soil. (Author)

As the civil war in Syria enters its fifth year, the Israeli government continues to provide humanitarian aid to Syrian civilians in Israeli hospitals. Many wounded Syrian children are treated at the Galilee Medical Center (GMC). Due to the patients' incomplete medical history and increasing infection rates in Syria, contact isolation and screening cultures for multi-drug resistant bacteria (MDR's) are conducted upon admission for all Syrian children. To describe the rate of MDR carriage in Syrian children and compare it to hospitalized Israeli children. Prospective collection of screening culture data of Syrian patients admitted to GMC between 6/2013-11/2014 and comparison with Israeli children admitted between 1-3/2014. Extended-spectrum beta- lactamase-producing Enterobateriaceae (ESBL), Vancomycin-resistant Enterococcus (VRE), Carbapenem-resistant Enterobacteriaceae (CRE), and Methicillin-resistant Staphylococcus aureus (MRSA) were considered MDR's. Of 47 pediatric Syrian patients, 41 were severely wounded. MDR's were found in 37 (79%) children; most of the isolates were ESBL+ Escherichia coli. Over half of the ESBL's were resistant to additional antibiotics such as sulfa and quinolones; no resistance to amikacin was found. In comparison, in 6 of 40 (15%) Israeli children, MDR's (all ESBL's) were found (p<0.001). In hospitalized Syrian children, contact isolation and screening cultures for MDR's have an important role in the prevention of nosocomial transmission and establishment of empiric antimicrobial protocols. In suspected infections in Syrian children, amikacin and carbapenems are the antimicrobials of choice. MDR's are carried to a lesser extent in Israeli children but due to their importance, further largescale research is needed.

Full Text Available A two years' old, white and brown Yankassa ewe, weighing 20 kg was presented with dystocia of about 48 h duration at Mabs Veterinary Centre Ltd, Lagos. On thorough physical and vaginal examination, there were evidences of feotal parts and foul smelling discharges per vagina. A systematic and calculated traction and retropulsion revealed schistosomus reflexus cojoined twins. There was a complete recovery of the ewe 3 days post operative management. Finally, this case reported a true schistosomus reflexus cojoined twins in Yankassa ewe which was successfully relieved through traction and retropulsion despite the supposedly small birth canal which precluded the procedure in ewes except for caesarian section or fetotomy

The plasma progesterone profile of six cycling and three pregnant Nellore ewes was estimated by radioimmunoassay. The progesterone level of cycling ewes started rising from undetectable level on the day of oestrus to a mean peak value of 0.41 ± 0.09ng/ml during post oestrus day 10 to 14 and then declined to undetectable levels 1 to 2 days before subsequent oestrus. But the progesterone levels of pregnant ewes exhibited further raise from the post oestrus day 14 to the day 40. However, no correlation between oestrous cycle length and the total progesterone produced during the oestrous cycle was observed. (author). 9 refs., 2 figs

Ewing's sarcoma is a highly malignant bone tumor found in children and adolescents, and the origin of this malignancy is not well understood. Here, we introduced a Ewing's sarcoma-associated genetic fusion of the genes encoding the RNA-binding protein EWS and the transcription factor ETS (EWS-ETS) into a fraction of cells enriched for osteochondrogenic progenitors derived from the embryonic superficial zone (eSZ) of long bones collected from late gestational murine embryos. EWS-ETS fusions efficiently induced Ewing's sarcoma-like small round cell sarcoma formation by these cells. Analysis of the eSZ revealed a fraction of a precursor cells that express growth/differentiation factor 5 (Gdf5), the transcription factor Erg, and parathyroid hormone-like hormone (Pthlh), and selection of the Pthlh-positive fraction alone further enhanced EWS-ETS-dependent tumor induction. Genes downstream of the EWS-ETS fusion protein were quite transcriptionally active in eSZ cells, especially in regions in which the chromatin structure of the ETS-responsive locus was open. Inhibition of β-catenin, poly (ADP-ribose) polymerase 1 (PARP1), or enhancer of zeste homolog 2 (EZH2) suppressed cell growth in a murine model of Ewing's sarcoma, suggesting the utility of the current system as a preclinical model. These results indicate that eSZ cells are highly enriched in precursors to Ewing's sarcoma and provide clues to the histogenesis of Ewing's sarcoma in bone.

The Syrian conflict has resulted in over 2.3 million child refugees in the Middle East and the prevalence of early marriage has reportedly increased among displaced Syrian families. This study explores the underlying factors contributing to child marriage among Syrian refugees in Lebanon with the goal of informing community-based strategies to address the issue. In July-August 2016, trained interviewers collected self-interpreted stories in Lebanon using Cognitive Edge's SenseMaker, a mixed-method data collection tool. Participants included married and unmarried Syrian girls, Syrian parents as well as married and unmarried men. Each participant shared a story about the experiences of Syrian girls and then interpreted the story by plotting their perspectives on a variety of questions. Patterns in the responses were analysed in SPSS and the accompanying qualitative narratives were reviewed to facilitate interpretation of the quantitative results. 1422 self-interpreted stories from 1346 unique participants were collected with 40% of shared stories focused on (n=332) or mentioning (n=245) child marriage. Quantitative data summarised the different perspectives of female and male participants. Syrian girls and mothers were more likely to share stories about protection/security and/or education and were more likely to report that girls were overprotected. Male participants were more likely to share stories about financial security as well as sexual exploitation of girls and more often reported that girls were not protected enough. Despite these gendered perspectives, many of the shared narratives highlighted similar themes of financial hardship, lack of educational opportunities and safety concerns around sexual and gender-based violence (SGBV). A complex myriad of factors contribute to early marriage including poverty, lack of educational opportunities and concerns about SGBV. Sexual exploitation under the guise of marriage is a reality for some Syrian girls. Gender

Elevated intakes of protein and energy may increase embryo mortality, but it is not clear whether fresh lucerne (Medicago sativa) pasture poses a risk. A two-year pen study using oestrous synchronised and artificially inseminated Merino ewes (n=175 in 2013 and 215 in 2014) evaluated whether feeding freshly cut lucerne pasture (mean crude protein 19.7%, metabolisable energy 9.4MJ/kg DM) at maintenance or ad libitum during different periods around insemination altered reproductive performance in comparison with ewes fed a Control diet (mean crude protein 7.8%, metabolisable energy 9.0MJ/kg DM) of pelleted faba bean hulls and oat grain hulls at maintenance. The proportion of pregnant ewes carrying multiple fetuses was reduced (P=0.026) when ewes were fed lucerne ad libitum between days 0 and 17 after insemination compared with the Control diet (0.18 and 0.34, respectively), but not when ewes were fed lucerne ad libitum between days 0 and 7 after insemination (0.22). Reproductive performance, including the proportion of ewes pregnant and the proportion with multiple fetuses, was not different (P>0.05) when ewes were fed lucerne at maintenance between days 0 and 7 compared with the Control diet. While reproductive performance was similar when ewes were fed lucerne at maintenance between 0 and 17 days after artificial insemination compared with pellets at maintenance, fetal numbers per pregnant ewe were reduced by feeding lucerne ad libitum after insemination.

Full Text Available Thirty four Syrian isolates of Tomato spotted wilt virus (TSWV collected from tomato and pepper were tested against five specific monoclonal antibodies using TAS-ELISA. The isolates were in two serogroups. Fourteen tomato and sixteen pepper isolates were similar in their reaction with MAb-2, MAb-4, MAb-5 and MAb-6, but did not react with MAb-7 (Serogroup 1. Meanwhile, four isolates collected from pepper reacted with all the MAbs used (Serogroup 2. The expected 620 bp DNA fragment was obtained by RT-PCR from six samples using a specific primer pair designed to amplify the nucleocapsid protein (NP gene of TSWV. The PCR products were sequenced and a phylogenetic tree was constructed. Sequence analysis revealed that the Syrian TSWV isolates were very similar at the nucleotide (97.74 to 99.84% identity and amino acid (96.17 to 99.03% identity sequences levels. The phylogenetic tree showed high similarity of Syrian TSWV isolates with many other representative isolates from different countries.

Transarticular spread of tumor is rare; it has only been reported in the sacroiliac joint, intervertebral disk spaces, and facet joints. The anatomic and kinetic characteristics of the sacroiliac joint, as well as the changes the joint undergoes during a lifetime, make it particularly vulnerable to transarticular tumor invasion. Although extremely rare, Ewing sarcoma can extend through the sacroiliac joint and be virtually indistinguishable radiologically from septic arthritis. Furthermore, the clinical presentation of a child with Ewing sarcoma can be similar to that of a child with osteomyelitis. Laboratory values are quite nonspecific and are not always helpful in differentiating between the entities. Therefore, the possibility of sacroiliac joint transarticular Ewing sarcoma should be considered in a child presenting with hip pain, despite clinical, radiological and laboratory findings suggesting an infectious process.

2016-07-01

Ewing's sarcoma, the second most common type of malignant bone tumor, generally occurs in children and young adults. The current treatment of Ewing's sarcoma comprises systemic anti‑cancer chemotherapy with complete surgical resection. However, the majority of patients with Ewing's sarcoma develop resistance to chemotherapy. The present study revealed an oncogenic role of lactate dehydrogenase‑A (LDHA) in the resistance of Ewing's sarcoma to cetuximab. LDHA was shown to be upregulated at the protein and mRNA level in cetuximab‑resistant Ewing's sarcoma tissues and a cell line. In addition, a link between LDHA‑induced glycolysis and cetuximab resistance in Ewing's sarcoma cells was revealed. Of note, inhibition of LDHA by either small interfering RNA or LDHA inhibitor oxamate significantly re‑sensitized cetuximab‑resistant cells to cetuximab. Combined treatment with LDHA inhibitor and cetuximab synergistically reduced the viability of cetuximab-resistant cells through the suppression of LDHA. The present study revealed a novel mechanism of cetuximab resistance from the perspective of cancer‑cell metabolism and provided a sensitization approach, which may aid in the development of anti-chemoresistance strategies for the treatment of cetuximab-resistant Ewing's sarcoma.

Ewes develop pelvic organ prolapse (POP) and may be a suitable model for preclinical studies evaluating cell-based therapies for POP. The aim of this study was to establish a clinical score of vaginal weakness and to compare POP Quantification System (POP-Q) values in conscious nulliparous and parous ewes and determine whether ewes are a suitable POP model. Ewes (n = 114) were examined while conscious, without sedation, and standing in a V conveyer by adapting the human POP-Q measurement. Ovine POP was defined as descent to the introitus from POP-Q points Aa 3 cm above the introitus on the anterior wall, Ap 3 cm above the introitus on the posterior wall, or increased Ba anterior wall descent above the urethra (≥0). A test-retest showed good inter- and intrarater reliability. There was no evidence of tissue mobility at Aa, Ap, Ba (all -3 cm) in nulliparous ewes (n = 14). In contrast, multiparous ewes had a median of -1 and interquartile range (IQR) (-2 to 0) for Aa, [0 (-1 to 0)] for Ap and [0 (-2.75 to 0)] for Ba (n = 33; P ewes. Ovine vaginal displacement was seen in 50.9 % of parous ewes and was strongly associated with parity (P = 0.003). A modified POP-Q in conscious ewes was established showing that the vaginal wall of parous animals has similar regions of weakness as do women and may be similarly related to parity. Ewes appear to be a representative preclinical model of human vaginal prolapse.

Full Text Available The current globalization system interconnects conflicts, problems and social policies in such a way that they do not only concern their countries of origin, but all the nations in the world. This paper is a bibliographic review with two main lines. The first one is focused on the root causes of the Syrian War and, as a consequence, the thousands of Syrian refugees it created. They were forced to flee from their country, and had to face several difficulties and overcome all kind of obstacles, which has been the source of many tragedies. The contribution of resilience as a social intervention approach with Syrian refugees from the point of view of Social Work is the second line of this paper. This social intervention approach is aimed at strengthening and empowering people against adversity in order to cope with trauma. This objective and the purpose of Social Work are one and the same: to guarantee and promote Human Rights all over the world.

Refugees have had major challenges to meet their health care needs throughout history especially in war zones and natural disaster times. The health care needs of Syrian refugees have been becoming an increasingly important issue. We aimed to examine the prevalence of post-traumatic stress disorder (PTSD) and explore its relation with various socioeconomic variables among Syrian refugees, who sought asylum in Turkey. This cross-sectional study was conducted in a tent city. Sample size calculation yielded 352 and the participants of the study were determined randomly. Experienced and native Arabic speaking, psychiatrist evaluated the participants. The frequency of PTSD was 33.5%. Through the binary logistic regression analysis, we calculated that the probability of having PTSD among Syrian refugees in our sample was 71%, if they had the following features: with female gender; being diagnosed with psychiatric disorder in the past; having a family history of psychiatric disorder; and experiencing 2 or more traumas. The findings of our study suggest that PTSD among Syrian refugees in Turkey might be an important mental health issue in refugee camps especially among female refugees, who were exposed to 2 or more traumatic events and had a personal or family history of psychiatric disorder.

The corpus luteum (CL) is an ovarian structure which is critical for the maintenance of reproductive cyclicity and pregnancy support. Diet and/or diet components may affect some luteal functions. FSH is widely used to induce multiple follicle development and superovulation. We hypothesized that FSH would affect luteal function in ewes fed different nutritional planes. Therefore, the aim of this study was to determine if FSH-treatment affects (1) ovulation rate; (2) CL weight; (3) cell proliferation; (4) vascularity; (5) expression of endothelial nitric oxide (eNOS) and soluble guanylate cyclase (sGC) proteins; and (6) luteal and serum progesterone (P4) concentration in control (C), overfed (O), and underfed (U) ewes at the early- and mid-luteal phases. In addition, data generated from this study were compared to data obtained from nonsuperovulated sheep and described by Bass et al. Ewes were categorized by weight and randomly assigned into nutrition groups: C (2.14 Mcal/kg; n = 11), O (2xC; n = 12), and U (0.6xC; n = 11). Nutritional treatment was initiated 60 d prior to day 0 of the estrous cycle. Ewes were injected with FSH on day 13-15 of the first estrous cycle, and blood samples and ovaries were collected at early- and mid-luteal phases of the second estrous cycle. The number of CL/ewe was determined, and CL was dissected and weighed. CL was fixed for evaluation of expression of Ki67 (a proliferating cell marker), CD31 (an endothelial cell marker), and eNOS and sGC proteins using immunohistochemistry and image analysis. From day 0 until tissue collection, C maintained, O gained, and U lost body weight. The CL number was greater (P ewes; however, concentration of P4 in luteal tissues was similar in both groups. Thus, in superovulated ewes, luteal cell proliferation and vascularity, expression of eNOS, and serum P4 concentration depend on the stage of luteal development, but not diet. Comparison to control ewes demonstrated several differences and some

2016-08-01

Full Text Available A 14-month-old intact male Syrian hamster was admitted for lethargy and hematuria. A total body radiographic image and abdominal ultrasonography showed the presence of a vesical calculus. During cystotomy, a sterile urine sample was obtained and sent to the diagnostic laboratory along with the urolith for analysis. Urine culture was found negative for bacterial growth, and the urolith was identified as a calcium-oxalate stone. Diet supplementation with palmitoylethanolamide, glucosamine and hesperidin was adopted the day after discharge. One year follow up revealed no presence of vesical calculi. Although this is the report of a single clinical case, this outcome differs from the results reported in the literature characterized by recurrences after few months. Considering the positive outcome and the beneficial properties of palmitoylethanolamide, glucosamine, and hesperidin, these nutritional elements in Syrian hamsters, are recommended to reduce recurrence after surgical treatment of urolithiasis.

Extraskeletal ewing sarcoma is a rare malignant tumor found in children and young adults. It commonly occurs in deep soft tissue of the trunk, especially in the paravertebral region and extremities. We report two cases of extraskeletal ewing sarcoma occurring as a cervical epidural tumor in elderly patients. The MRI and CT findings showed that paravertebral epidural tumors had invaded the spinal canal through the intervertebral foramen. At T1-weighted MR imaging, the masses were isointense to muscle, and at T2* and T2-weighted images were hyperintense, and heterogeneous contrast enhancement was observed. Extraskeletal ewing sarcoma, though quite rare, should be borne in mind in the differential diagnosis of paraspinal epidural tumors.

Extraskeletal ewing sarcoma is a rare malignant tumor found in children and young adults. It commonly occurs in deep soft tissue of the trunk, especially in the paravertebral region and extremities. We report two cases of extraskeletal ewing sarcoma occurring as a cervical epidural tumor in elderly patients. The MRI and CT findings showed that paravertebral epidural tumors had invaded the spinal canal through the intervertebral foramen. At T1-weighted MR imaging, the masses were isointense to muscle, and at T2* and T2-weighted images were hyperintense, and heterogeneous contrast enhancement was observed.

The Delvotest method detection limits per manufacturer's instructions at a fixed reading time of 3 h for 24 antimicrobial agents were determined in ewe milk by photometric measurement. For each drug, eight concentrations were tested on 20 ewe milk samples from individual ewes. Detection limits, determined by means of logistic regression models, were (microg/kg): 3, amoxycillin; 2, ampicillin; 18, cloxacillin; 1, penicillin "G"; 34, cefadroxil; 430, cephalosporin "C"; 40, cephalexin; 20, cefoperazone; 33, Ceftiofur; 18, cefuroxime; 6100, streptomycin; 1200, gentamycin; 2600, neomycin; 830, erythromycin; 100, tylosin; 180, doxycycline; 320, oxytetracycline; 590, tetracycline; 88, sulfadiazine; 44, sulfamethoxazole; 140, sulfametoxypyridazine; 48, sulfaquinoxaline; 12,000, chloramphenicol; and 290, trimethoprim. Whereas the beta-lactam antibiotics, sulphonamides, and tylosin were detected by Delvotest method at levels equal to those of maximum residue limits, its sensitivity needs to be enhanced to detect aminoglycosides, tetracyclines, streptomycin, chloramphenicol, and trimethoprim residues in ewe milk or to develop an integrated residue detection system for ewe milk with different sensitive microorganisms for each group of antiinfectious agents.

Ewing's sarcoma is a malignant bone tumor that can occur anywhere in the body, but it is most commonly observed in the long bones of the arms and legs, the pelvis and in the chest. The predominant sites of metastasis include the lung (38%), bone (including the spine; 31%), and the bone marrow (11%). Metastasis of Ewing's sarcoma to the central nervous system (CNS) is relatively rare, and most of the previous reports have demonstrated involvement of the bony calvarium or brain parenchyma. We describe here the imaging findings of dural metastasis of Ewing's sarcoma, and these imaging findings have not been previously reported on in the medical literature. In conclusion, dural metastasis of Ewing's sarcoma is very rare and its imaging characteristics are similar to those of a primary tumor, which mimic the findings of a schwannoma or meningioma. Despite its rarity, secondary Ewing's sarcoma may be included in the differential diagnosis of extra-axial dural masses.

Primary Ewing's sarcoma originating in the pericranium is an extremely rare disease entity. A 9-year-old female patient was admitted to our department due to a left temporal subcutaneous mass. The mass was localized under the left temporal muscle and attached to the surface of the temporal bone. Head computed tomography revealed a mass with bony spicule formation on the temporal bone, however, it did not show bone destruction or intracranial invasion. F-18 fluorodeoxyglucose positron emission tomography showed no lesions other than the mass on the temporal bone. Magnetic resonance imaging showed that the mass was located between the temporal bone and the pericranium. The mass was completely resected with the underlying temporal bone and the overlying deep layer of temporal muscle, and was diagnosed as primary Ewing's sarcoma. Because the tumor was located in the subpericranium, we created a new classification, "pericranial Ewing's sarcoma," and diagnosed the present tumor as pericranial Ewing's sarcoma. We herein present an extremely rare case of primary pericranial Ewing's sarcoma that developed on the temporal bone.

Ewing's sarcoma in childhood is a disease from family of the peripheral primitive neuroectodermal tumours. For a period of 16 y (1984-2000), 34 children with Ewing's sarcoma were treated and followed in our department. Twenty-seven of these patients were without distant metastases. Complex treatment was applied to all these patients-chemotherapy VACA (vincristine, actinomycin D, cyclophosphamide, adriamycin), local radiotherapy to a total dose of 50-56 Gy ± surgery. After, a local tumour control was achieved in 11 children with non-metastatic Ewing's sarcoma, elective whole lung irradiation to a total dose of 12-15 Gy was applied. Our experience in these 11 patients with non-metastatic Ewing's sarcoma, in whom elective lung irradiation was applied, showed significant reduction in the lung metastases, improved free of disease survival and overall survival. The achieved good treatment results necessitate extending this treatment approach through defining the risk groups of patients, suitable for elective lung radiotherapy combined with chemotherapy in non-metastatic Ewing's sarcoma.

Nucleophosmin (NPM) is a novel prognostic biomarker for Ewing's sarcoma. To evaluate the prognostic utility of NPM, we conducted an interactomic approach to characterize the NPM protein complex in Ewing's sarcoma cells. A gene suppression assay revealed that NPM promoted cell proliferation and the invasive properties of Ewing's sarcoma cells. FLAG-tag-based affinity purification coupled with liquid chromatography-tandem mass spectrometry identified 106 proteins in the NPM protein complex. The functional classification suggested that the NPM complex participates in critical biological events, including ribosome biogenesis, regulation of transcription and translation, and protein folding, that are mediated by these proteins. In addition to JAK1, a candidate prognostic biomarker for Ewing's sarcoma, the NPM complex, includes 11 proteins known as prognostic biomarkers for other malignancies. Meta-analysis of gene expression profiles of 32 patients with Ewing's sarcoma revealed that 6 of 106 were significantly and independently associated with survival period. These observations suggest a functional role as well as prognostic value of these NPM complex proteins in Ewing's sarcoma. Further, our study suggests the potential applications of interactomics in conjunction with meta-analysis for biomarker discovery. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The Syrian Refugee Crisis: What Nurses Need to Know.

2017-04-01

The civil war in Syria that began in 2011 has displaced millions of Syrians of all ages. While the number that have arrived in the United States is small in comparison to many other countries, it is important that nurses and other healthcare workers here understand that many of them have faced considerable trauma and endured stresses. Most of them are Muslims. Muslims in the United States and elsewhere represent a heterogeneous group of people with a long intellectual and cultural history. Islamic cultural patterns do pose unique barriers to a primarily Anglo-Saxon medical system that medical practitioners need to consider in order to avoid misunderstanding and provide culturally sensitive care. The authors discuss the Syrian refugee crisis and the experience of being a Muslim or Arab American patient in U.S. healthcare settings.

The current study explores the perceived quality of life of Syrian refugees who have entered the Kurdistan Region of Iraq. Two hundred and seventy participants residing in refugee camps in the Erbil region in Kurdistan completed the WHOQOL-BREF, which measures Quality of Life (QOL) within four domains; physical, psychological, social relationships and environment. Syrian refugees in Kurdistan scored significantly lower for general population norms on physical health, psychological and environment QOL, and score significantly lower for physical health and psychological QOL for refugees in the Gaza strip. However, respondents in the current sample scored significantly higher on environment QOL compared to refugees in the Gaza strip, and significantly higher on all the QOL domains than those reported for refugees in West Africa. Finally, Syrian refugees in Kurdistan scored significantly higher than general population norms for social relationships QOL. The current findings provide the first report of QOL domain scores among Syrian refugees in the Kurdistan camps and suggest that social relationships and environmental QOL circumstances are relatively satisfactory, and that further investigation might be focused on physical and psychological QOL.

An increasing number of patients are raising their voices in online forums to exchange health-related information. Facebook is the leading social media platform with more than 1 billion international daily users recorded in the summer of 2015. Facebook has a dynamic audience and is utilized in a number of ways, discussing medical issues being one of them. Ewing sarcoma mainly affects teenagers and young adults. Additionally, many individuals within this age group are regular users of Facebook. However, little is known about the impact of this modern way of communication via Web-based platforms on patients with Ewing sarcoma and their social environment. The aim of this study was to analyze and compare Ewing sarcoma patients' and relatives' behavior on Facebook to draw conclusions regarding the impact of Facebook on Ewing sarcoma treatment. We examined a Facebook group named "Ewing Sarcoma Awareness" that is used to exchange information for both patients and relatives regarding Ewing sarcoma. A self-designed questionnaire was used to compare patients' and relatives' answers. Additionally, we analyzed all processes (posts, likes, threads, links) in the group for 6 consecutive months. A total of 65 members of the Facebook group (26 patients, 39 relatives) out of 2227 international group members participated in our study. More than 70% (46/65) of all participants reported that they use the group Ewing Sarcoma Awareness as a source of information about Ewing sarcoma. Of the participants, 89% (58/65) agreed on our scale from a little to a lot that being in contact with other affected people through the group makes it easier to handle the diagnosis. In this study, 20% (13/65) of all participants reported that the group affected their choice of treatment and 15% (10/65) of participants were influenced in the selection of their specialist. Regarding the recommendation of the Facebook group toward other people, significant differences (P=.003) were found comparing patients

A series of experiments was designed to assess the effect of a treatment protocol (U-synch) for inducing oestrus and ovulation out of the breeding season in adult ewes and ewe lambs. The protocol consisted of a 7-day treatment with an intravaginal progesterone-releasing device (IPRD), administration of GnRH at IPRD insertion on Day 0, and equine chorionic gonadotropin (eCG) and prostaglandin F2α at IPRD removal on Day 7. In Experiment 1, 50 or 100 μg GnRH were sufficient to induce ovulation at the beginning of the protocol in 3/9 and 4/9 ewes, respectively; while the resulting proportion of sheep ovulating after the treatment protocol was 88.9% and 77.8% in ewes initially treated with 50 or 100 μg GnRH, respectively. In Experiment 2, the proportion of Romney-cross ewe lambs ovulating was greater (P<0.0001) in the U-synch group (95.4%) than in the untreated Control group (3.2%). In Experiment 3, pregnancy rates of Dorset-cross sheep in the U-synch (60.7%) and Standard (12-day IPRD and eCG treatment; 56.5%) groups were greater (P=0.01) than in the untreated Control group (43.4%). The incidence of twin pregnancies was greater (P=0.005) in the U-synch group than in the Control group. A 7-day IPRD treatment including GnRH treatment at device insertion and eCG treatment at device removal induced oestrus and ovulation during the non-breeding season in a high proportion of mature ewes and ewe lambs. High pregnancy rates to natural mating, with a low rate of triplet pregnancies, were also observed. Copyright © 2015 Elsevier B.V. All rights reserved.

To compare obstetric and perinatal outcomes of Syrian refugee pregnants and Turkish counterparts who gave birth at a tertiary center in İstanbul. A retrospective study including the birth records of 704 Syrian refugees and 744 Turkish pregnant women between January 2016 and May 2017 were analyzed. Demographic data, obstetric and neonatal outcomes were compared. The primary aims of this study were to evaluate the pregnancy outcomes and cesarean rates between the groups. The secondary outcomes were the use of antenatal vitamin supplementation, hemoglobin-hematocrit values, and maternal complications. Our results showed that the use of folic acid and iron supplementation rates during pregnancy were similar between the groups (folic acid supplementation 8.1% vs 6.5%, p=0.264; iron supplementation 20.7% vs 19.6%, p=0.125; respectively for Turkish women and Syrian refugees). Cesarean rates were significantly higher for Turkish patients than in Syrian refugees (42.7% vs 32.7%; pyrian refugees (37.7±2.3 vs 36.4±2.3 weeks, pyrian refugees, respectively, p=0.105). Although obstetric complications were seen more often in Syrian refugees, it did not reach statistical difference (9.7% vs 8.1%, respectively, p=0.285). Syrian refugees use antenatal vitamin supplementations at similar rates to Turkish citizens and obstetric and perinatal outcomes are similar between the groups.

Introduction : Ewing's sarcoma is the second most common primary malignant tumor of bone found in children after Osteosarcoma. It accounts for 4-9% of primary malignant bone tumors and it affects bones of the skull or face in only 1-4% of cases. Hence it rarely affects the head and neck. Subject and Method : In this case report, we describe a case of primary Ewing's sarcoma occurring in the temporal bone. The tumor was surgically excised, and the patient underwent chemotherapy for ten months. Results : Neither recurrence nor distant metastasis was noted in these 10 months after surgery but about 18 months after surgery our patient was expired. Conclusion : Although the prognosis of Ewing's sarcoma is generally poor because of early metastasis to the lungs and to other bones, a review of the article suggested that Ewing's sarcoma occurring in the skull can often be successfully managed by intensive therapy with radical excision and chemotherapy. This result was supported by the case reported here.

Induction of cervical dilation for transcervical embryo transfer in ewes

Science.gov (United States)

2014-01-01

Background A major limitation in the application of assisted reproductive technologies in sheep arises from the inability to easily traverse the uterine cervix. The cervix of the non-pregnant ewe is a narrow and rigid structure, with 5–7 spiral folds and crypts that block its lumen. The first two folds closest to the vagina appear to be the greatest obstacle for the instrument insertion into the sheep cervix. Therefore, the dilation of the distal part of the cervix could provide the conformational change necessary to perform non-invasive transcervical procedures. The present study set out to assess the efficacy of Cervidil®, a patented dinoprostone (PgE2)-containing vaginal insert with a controlled-release mechanism, to safely induce sufficient cervical dilation for the purpose of transcervical embryo transfer (TCET) in cyclic ewes. Methods The transfer of frozen-thawed ovine embryos was attempted in 22 cross-bred Rideau Arcott x Polled Dorset ewes, with or without the pre-treatment with Cervidil® for 12 or 24 h prior to TCET. Results Cervical penetration rate was significantly improved after Cervidil® pre-treatment, with 55% (6/11) of treated versus 9% (1/11) of control animals successfully penetrated (χ2-test, p ewes that were penetrated, 67% (4/6) had been exposed to Cervidil(R) for 24 h and 33% (2/6) had had a 12-h exposure (p > 0.05). Variations in the age, weight, genotype, parity, lifetime lamb production (LLP) and post-partum interval (PPI) between penetrated and non-penetrated ewes were not significant (p > 0.05). The time taken to traverse the uterine cervix was negatively correlated (p ewes, but no fetuses were detected ultrasonographically 55 days post-TCET. Conclusions The present results indicate a significant benefit of using Cervidil® for inducing cervical dilation during the mid-luteal phase in ewes but the reason(s) for impaired fertility after the transfer of frozen-thawed ovine embryos remains to be elucidated.

Introduction The Syrian conflict has resulted in over 2.3 million child refugees in the Middle East and the prevalence of early marriage has reportedly increased among displaced Syrian families. This study explores the underlying factors contributing to child marriage among Syrian refugees in Lebanon with the goal of informing community-based strategies to address the issue. Methods In July–August 2016, trained interviewers collected self-interpreted stories in Lebanon using Cognitive Edge’s SenseMaker, a mixed-method data collection tool. Participants included married and unmarried Syrian girls, Syrian parents as well as married and unmarried men. Each participant shared a story about the experiences of Syrian girls and then interpreted the story by plotting their perspectives on a variety of questions. Patterns in the responses were analysed in SPSS and the accompanying qualitative narratives were reviewed to facilitate interpretation of the quantitative results. Results 1422 self-interpreted stories from 1346 unique participants were collected with 40% of shared stories focused on (n=332) or mentioning (n=245) child marriage. Quantitative data summarised the different perspectives of female and male participants. Syrian girls and mothers were more likely to share stories about protection/security and/or education and were more likely to report that girls were overprotected. Male participants were more likely to share stories about financial security as well as sexual exploitation of girls and more often reported that girls were not protected enough. Despite these gendered perspectives, many of the shared narratives highlighted similar themes of financial hardship, lack of educational opportunities and safety concerns around sexual and gender-based violence (SGBV). Conclusions A complex myriad of factors contribute to early marriage including poverty, lack of educational opportunities and concerns about SGBV. Sexual exploitation under the guise of marriage

The substitution of ewe milk with more economic cow milk is a common fraud. Here we present a capillary electrophoresis method for the quantification of ewe milk in ovine/bovine milk mixtures, which allows for the rapid and inexpensive recognition of ewe milk adulteration with cow milk. We utilized a routine CE method for human blood and urine proteins analysis, which fulfilled the separation of skimmed milk proteins in alkaline buffer. Under this condition, ovine and bovine milk exhibited a recognizable and distinct CE protein profiles, with a specific ewe peak showing a reproducible migration zone in ovine/bovine mixtures. Based on ewe specific CE peak, we developed a method for ewe milk quantification in ovine/bovine skimmed milk mixtures, which showed good linearity, precision and accuracy, and a minimum amount of detectable fraudulent cow milk equal to 5%.

The study investigated concomitant effect of gestation and high ambient temperature under a tropical environment on rectal temperature (RT), respiratory rate (RR) and heart rate (HR) responses in Yankasa ewes. Twenty Yankasa ewes, consisting of ten pregnant and ten non-pregnant ewes, were used for the study. Ewes were synchronised and bred, such that each gestation phase coincided with different periods of the dry-seasons, early-gestation (cold/harmattan), mid-gestation (peak hot-dry) and late-gestation (late hot-dry). The RT, RR and HR were recorded thrice, 2 days apart at middle of each gestation period at 06:00, 14:00 and 18:00 h, concurrently with dry- (DBT) and wet-bulb temperatures of the experimental pen. The DBT was positively correlated with RT, RR during the different gestation stages. The RT significantly (P ewes, with peak at 14:00 h. Values of RT and RR were higher (P ewes at mid- and late-gestation, respectively. Mean RT was lower (P ewes at early-gestation (cold-dry). The HR was (P ewes during the different gestation phases. In conclusion, ambient temperature and gestation concomitantly modulate diurnal thermoregulatory responses of the ewes to hot-dry season. Adequate measures should be adopted to mitigate adverse impact of prolonged high RR on the dam and the foetus during the peak of ambient temperature prevailing in the tropical Savannah environment.

The aim of this study was to compare the heart rate (HR) patterns in rams mated with estrous or nonestrous ewes and in mated estrous and nonestrous ewes () during courtship and mating. For this purpose, HR and behavior were recorded using a radio telemetry recording system and a closed-circuit television system with video recording, respectively. Rams were joined with either an estrous ( = 10) or a nonestrous ( = 10) ewe that was restrained in a stanchion by the neck. Data were continuously recorded until each ram performed 3 ejaculations. Eight days later, the HR of the 10 estrous and 10 nonestrous ewes was recorded during mating. Although the time between entrance into the yard and the first ejaculation was similar across rams, rams that mounted estrous ewes were faster at attaining their second (3min5s ± 17 s vs. 5min28s ± 18 s) and third (7min58s ± 45 s vs. 12 min ± 1min14s) ejaculations (all ewes. In all cases, HR reached maximum values immediately after each ejaculation and the HR pattern was similar across ejaculations (first, second, and third). Although HR was similar between estrous and nonestrous ewes before mating, nonestrous ewes had higher HR ( ewes displayed shorter interejaculation periods but HR did not differ between groups of rams during any ejaculation (first, second, or third), 2) HR for both groups of rams peaked shortly after each ejaculation, and 3) HR increased more in nonestrous than in estrous ewes while mating.

Sacral Ewing's Sarcoma and Challenges in it's Diagnosis on MRI

Full Text Available A 15-yr old boy presented with low backache for 4 months associated with weakness of left lower limb. MRI of lumbosacral spine showed a sacral lesion with intraspinal and presacral soft tissue extension with neural compression. A diagnosis of tuberculosis was considered in the view of high prevalence in this part of the world, however biopsy revealed Ewing's sarcoma. Ewing's tumor of sacrum is rare, but should be suspected in low backache in children. Differential diagnosis for a sacral lesion includes tuberculosis, pyogenic osteomyelitis, lymphoma, chordoma, osteosarcoma and Ewing's sarcoma. MRI is sensitive in detecting these lesions but is nonspecific requiring histopathological examination for confirmation.

Merino sheep in Australia experience periods of variable feed supply. Merino sheep can be bred to be more resilient to this variation by losing less BW when grazing poor quality pasture and gaining more BW when grazing good quality pasture. Therefore, selection on BW change might be economically attractive but correlations with other traits in the breeding objective need to be known. The genetic correlations (rg) between BW, BW change, and reproduction were estimated using records from approximately 7,350 fully pedigreed Merino ewes managed at Katanning in Western Australia. Number of lambs and total weight of lambs born and weaned were measured on approximately 5,300 2-yr-old ewes, approximately 4,900 3-yr-old ewes, and approximately 3,600 4-yr-old ewes. On a proportion of these ewes BW change was measured: approximately 1,950 2-yr-old ewes, approximately 1,500 3-yr-old ewes, and approximately 1,100 4-yr-old ewes. The BW measurements were for 3 periods. The first period was during mating period over 42 d on poor pasture. The second period was during pregnancy over 90 d for ewes that got pregnant on poor and medium quality pasture. The third period was during lactation over 130 d for ewes that weaned a lamb on good quality pasture. Genetic correlations between weight change and reproduction were estimated within age classes. Genetic correlations were tested to be significantly greater magnitude than 0 using likelihood ratio tests. Nearly all BW had significant positive genetic correlations with all reproduction traits. In 2-yr-old ewes, BW change during the mating period had a positive genetic correlation with number of lambs weaned (rg = 0.58); BW change during pregnancy had a positive genetic correlation with total weight of lambs born (rg = 0.33) and a negative genetic correlation with number of lambs weaned (rg = -0.49). All other genetic correlations were not significantly greater magnitude than 0 but estimates of genetic correlations for 3-yr-old ewes were

Group size (GS) and space allowance have major implications for the welfare of production species, however their effects are often confounded. In a previous study we investigated the impact of varying space allowance at constant GS. In the present work we report the consequences of varying GS on pregnant ewes while controlling space allowance. We housed ewes at 6 (GS6) or 12 ewes/enclosure (GS12), while controlling space allowance to 1.5 m2/ewe (3 enclosures/treatment), and necessarily varying enclosure size. Therefore, when indicating GS effects we implicitly reflect a confounding effect with that of enclosure size. Movement, use of space, behaviour, serum cortisol concentration and body condition score (BCS) were collected during the last 12 gestation weeks. Movement, use of space, and behaviour were collected every other week, during 2 days/week, using 10 minute continuous scan samplings. Blood was collected during weeks 10, 13, 17, and 21 of gestation, and BCS during weeks 15 and 21. Data were analysed using repeated measures, generalized linear mixed models, with GS, week, and their interaction as fixed effects, and enclosure as random effect. GS mainly affected movement and use of space. GS12 ewes walked longer distances using longer steps (Pewe is given during gestation, larger GS will result in larger effective space, and no major implications for the welfare of ewes should be expected as GS increases. Ewes will adapt their movement patterns and use of space to enclosure size, and no further behavioural, physiological and physical consequences should be expected. PMID:27893817

Extraskeletal Ewing's sarcoma is a rare tumor, and the management of airway compromise in case of cervical Ewing's sarcoma has not been established. This report describes the case of a patient with retrotracheal Ewing's sarcoma and discusses a successful approach to airway management. A 12-year-old male presented with a 2-week history of sore throat and sleep-disordered breathing and 48 hours of stridor. Imaging confirmed a retrotracheal soft tissue mass with airway compromise. A planned and controlled approach to his airway management resulted in a secure airway prior to definitive treatment.

Reproduction in tropical sheep is not affected by season, whereas the reproductive cycle of temperate-climate breeds such as Suffolk depends on the photoperiod. Close contact with tropical ewes during the anestrous period might induce Suffolk ewes to cycle, making the use of artificial light or hormonal treatments unnecessary. However, the integration of both breeds within the social group would be necessary to trigger this effect, and so the aim of the experiment was to determine the speed of integration of 2 groups of Saint Croix and Suffolk ewes into a single flock, according to space allowance and previous experience. For this, 6 groups of 10 ewes (half from each breed) from both breeds, housed at 2 or 4 m/ewe (3 groups/treatment) and with or without previous contact with the other breed, were monitored for 3 d. Each observation day, the behavior, movement, and use of space of ewes were collected during 10 min at 1-h intervals between 0900 and 1400 h. Generalized linear mixed models were used to test the effects of breed, space allowance, and previous experience on behavior, movement, and use of space. Net distances, interbreed farthest neighbor distance, mean interbreed distance, and walking frequencies were greater at 4 m/ewe ( ewe were greatest for Saint Croix ewes, whereas the opposite was found for lying down ( ewes showed larger intrabreed nearest neighbor distances, minimum convex polygons, and home range overlapping ( ewes at 4 m/ewe showed longest total distances and step lengths and greatest movement activity ( ewes walked longer total distances during Day 1 and 2 ( ewes kept longer interindividual distances during Day 1 ( ewes did not fully integrate into a cohesive flock, with each breed displaying specific behavioral patterns. Decreasing space allowance and previous experience resulted in limited benefits for the successful group cohesion. Longer cohabitation periods might result in complete integration, although practical implementation might be

By the summer of 2014, the Syrian crisis resulted in a regional humanitarian emergency with 2.9 million refugees, including 608,000 in Jordan. These refugees access United Nations High Commissioner for Refugees (UNHCR)-sponsored clinics or Jordan Ministry of Health clinics, including tuberculosis diagnosis and treatment. Tuberculosis care in Syria has deteriorated with destroyed health infrastructure and drug supply chain. Syrian refugees may have undiagnosed tuberculosis; therefore, the UNHCR, the International Organization for Migration (IOM), the National Tuberculosis Program (NTP), and the Centers for Disease Control and Prevention developed the Public Health Strategy for Tuberculosis among Syrian Refugees in Jordan. This case study presents that strategy, its impact, and recommendations for other neighboring countries. UNHCR determined that World Health Organization (WHO) criteria for implementing a tuberculosis program in an emergency were met for the Syrian refugees in Jordan. Jordan NTP assessed their tuberculosis program and found that access to Syrian refugees was the one component of their program missing. Therefore, a strategy for tuberculosis control among Syrian refugees was developed. Since that development through work with IOM, UNHCR, and NTP, tuberculosis case detection among Syrian refugees is almost 40 % greater (74 cases/12 months or 1.01/100,000 monthly through June 2014 vs. 56 cases/16 months or 0.73/100,000 monthly through June 2013) using estimated population figures; more than two fold the 2012 Jordan tuberculosis incidence. Additionally, the WHO objective of curing ≥85 % of newly identified infectious tuberculosis cases was met among Syrian refugees. Tuberculosis (TB) rates among displaced persons are high, but increased detection is possible. High TB rates were found among Syrian refugees through active screening and will probably persist as the Syrian crisis continues. Active screening can detect tuberculosis early and reduce risk

Safadi, Chafic

1986-01-01

The Syrian Arab territories are located in the warm moderate region, under arid and semi-arid conditions. In spite of the occurrence of main springs and permanent rivers, groundwater resources available are a limiting factor for socio-economic development in several Syrian regions. Investigation and development of these resources are facing serious problems, for which the application of isotope and nuclear techniques could be a significant process and a deterministic tool. So far, and on the light of current applications, the Syrian Arab Republic is already involved in the isotopic hydrology sector, and so it is needful to set up, in the near future, a relevant unit, on a centralized basis covering the concerned authorities demands, under co-ordinated and integrated conditions. The international co-operation would be of a concrete importance in this respect, to provide the mentioned unit with equipment, training of scientific and technical staff, and consultancy services during the period of establishment. 14 refs.

2007-09-01

Full Text Available Abstract Background Clinical mastitis is an important disease in sheep. The objective of this work was to identify causal bacteria and study certain epidemiological and clinical features of clinical mastitis in ewes kept for meat and wool production. Methods The study included 509 ewes with clinical mastitis from 353 flocks located in 14 of the 19 counties in Norway. Clinical examination and collection of udder secretions were carried out by veterinarians. Pulsed-field gel electrophoresis (PFGE was performed on 92 Staphylococcus aureus isolates from 64 ewes. Results and conclusion S. aureus was recovered from 65.3% of 547 clinically affected mammary glands, coagulase-negative staphylococci from 2.9%, enterobacteria, mainly Escherichia coli, from 7.3%, Streptococcus spp. from 4.6%, Mannheimia haemolytica from 1.8% and various other bacteria from 4.9%, while no bacteria were cultured from 13.2% of the samples. Forty percent of the ewes with unilateral clinical S. aureus mastitis also had a subclinical S. aureus infection in the other mammary gland. Twenty-four of 28 (86% pairs of S. aureus isolates obtained from clinically and subclinically affected mammary glands of the same ewe were indistinguishable by PFGE. The number of identical pairs was significantly greater than expected, based on the distribution of different S. aureus types within the flocks. One-third of the cases occurred during the first week after lambing, while a second peak was observed in the third week of lactation. Gangrene was present in 8.8% of the clinically affected glands; S. aureus was recovered from 72.9%, Clostridium perfringens from 6.3% and E. coli from 6.3% of the secretions from such glands. This study shows that S. aureus predominates as a cause of clinical ovine mastitis in Norway, also in very severe cases. Results also indicate that S. aureus is frequently spread between udder halves of infected ewes.

Full Text Available The current study explores the perceived quality of life of Syrian refugees who have entered the Kurdistan Region of Iraq. Two hundred and seventy participants residing in refugee camps in the Erbil region in Kurdistan completed the WHOQOL-BREF, which measures Quality of Life (QOL within four domains; physical, psychological, social relationships and environment. Syrian refugees in Kurdistan scored significantly lower for general population norms on physical health, psychological and environment QOL, and score significantly lower for physical health and psychological QOL for refugees in the Gaza strip. However, respondents in the current sample scored significantly higher on environment QOL compared to refugees in the Gaza strip, and significantly higher on all the QOL domains than those reported for refugees in West Africa. Finally, Syrian refugees in Kurdistan scored significantly higher than general population norms for social relationships QOL. The current findings provide the first report of QOL domain scores among Syrian refugees in the Kurdistan camps and suggest that social relationships and environmental QOL circumstances are relatively satisfactory, and that further investigation might be focused on physical and psychological QOL.

Ewing sarcoma is the second most common primary malignant bone cancer in children and adolescents. Clinical presentation is usually dominated by local pain and a palpable mass. These symptoms justify imaging investigations: the first one, when an osseous lesion is suspected, is usually a conventional radiograph in two planes. Ewing sarcoma appears as a poorly defined osteolytic lesion that may frequently be associated with cortical erosion or laminar periosteal response ("onion skin"). However, this aspect is not pathognomonic and the definitive diagnosis is made by biopsy. Absence of pain or an unusual localization can lead to misdiagnosis. We report the case of a 7-year-old boy with Ewing sarcoma located in the mandible with a clinical picture including progressive mandibular swelling but no pain. Copyright © 2015 Elsevier Masson SAS.

In this Research Communication we assessed factors affecting colostrum quality of dairy Lacaune ewes using the Brix-refractometer. Colostrum from 536 lambings from one commercial intensive dairy Lacaune farm were analysed for the following factors with potential influence in colostrum quality: (1) ewe parity (n = 84-132), (2) length of previous dry period (PDP) (n = 23-214), (3) age at first lambing (AFL) of primiparous ewes (n = 9-88), (4) lambing season (n = 192 or 344), and (5) year (2011-2013, n = 142-203). Parity significantly affected colostrum quality, with primiparous ewes showing the highest Brix refractometer values (22·6 ± 5·6%, P ewes. PDP length also significantly affected colostrum quality: ewes with the shortest PDP showed the worst quality (16·8 ± 4·2%, P ewes under intensive management conditions and they further show the usefulness of the Brix refractometer for providing a rough estimation of colostrum quality on-farm. However, further studies are needed to determine a validated cut-off Brix value for identifying good-quality colostra in ovine species.

Andreia Barros de Moraes

2016-08-01

Full Text Available Mortality of perinatal lambs and low weight at weaning cause huge liabilities to farmers. Current study describes maternal-filial behavior and evaluates the use of maternal behavior score (MBS to estimate the behavior of ewes and lambs soon after birth, and correlate it with lamb mortality and performance during lactation. Thirty-seven Corriedale ewes were used in a completely randomized design. MBS was assessed up to 24 hours after birth, taking into consideration the distance of the ewe from the lamb at the approach of a person. Maternal behavior, placental weight, weight gain of the lambs until weaning and their survival rate were also evaluated until two hours after lambing. More than 90% of the ewes had adequate maternal behavior, with parental care, even though ewes were very sensitive to the presence of people. There was no significant correlation between MBS and maternal behavior, lamb mortality rate and live weight gain. Under these conditions, MBS was not a useful tool to estimate maternal behavior and performance of lambs.

Ewing's sarcoma is a common malignant bone tumour presenting in children and young adults. Rarely extra- skeletal soft tissues and visceral organs can also be the site of origin of Ewing's sarcoma. Primary pulmonary Ewing's sarcoma is an extremely rare malignancy which occurs in the paediatric population. We report an unusual case of primary pulmonary Ewing's sarcoma in a nine year old girl who presented with features of superior vena cava syndrome in the emergency department. The diagnosis was confirmed pathologically both by light microscopy and immunohistochemistry. The patient was put on chemotherapy and surgery was planned but the patient expired within three days of starting chemotherapy.

Hemsworth, Paul; Doyle, Rebecca

2017-01-01

Simple Summary The aim of this study was to assess the reliability and practicality of 10 animal-based welfare measures for extensively managed ewes, which were derived from the scientific literature, previous welfare protocols and through consultation with veterinarians and animal welfare scientists. Measures were examined on 100 Merino ewes, which were individually identified and repeatedly examined at mid-pregnancy, mid-lactation and weaning. Body condition score, fleece condition, skin lesions, tail length, dag score and lameness are proposed for on-farm use in welfare assessments of extensive sheep production systems. These six welfare measures, which address the main welfare concerns for extensively managed ewes, can be reliably and feasibly measured in the field. Abstract The reliability and feasibility of 10 animal-based measures of ewe welfare were examined for use in extensive sheep production systems. Measures were: Body condition score (BCS), rumen fill, fleece cleanliness, fleece condition, skin lesions, tail length, dag score, foot-wall integrity, hoof overgrowth and lameness, and all were examined on 100 Merino ewes (aged 2–4 years) during mid-pregnancy, mid-lactation and weaning by a pool of nine trained observers. The measures of BCS, fleece condition, skin lesions, tail length, dag score and lameness were deemed to be reliable and feasible. All had good observer agreement, as determined by the percentage of agreement, Kendall’s coefficient of concordance (W) and Kappa (k) values. When combined, these nutritional and health measures provide a snapshot of the current welfare status of ewes, as well as evidencing previous or potential welfare issues. PMID:29295551

Many surveys have underlined the high levels of distress Syrian refugees have endured since the conflict aroused in their country, yet few have used reliable diagnostic tools for the clinical assessment of resulting mental disorders. The aim of our study is to assess for the onset of new depressive disorders following the Syrian war, and to investigate the correlation of religiosity with depression. Single individual interviews were used, in a sample of 310 Syrian forced migrants, retrospectively assessing for depressive disorders with onset at different timelines of the conflict outbreak. Religiosity was assessed in a cross-sectional design using a reliable, recently developed and tested tool. Bivariate analysis and logistic regression analysis were used with a level of significance at 0.05. The prevalence of current depression was 43.9% (95% Confidence Interval (CI): 38.5-49.4%) with no difference across all socio-demographic factors, including gender. The overall mean for religiosity for the current sample was moderate (mean=9.76; standard deviation SD=2.34). No substantial correlation was found with religiosity. The prevalence rate for pre-war depression was 6.5% (95% CI: 4.2-9.8%) following the global pattern of socio-demographic epidemiological characteristics. Prevalence for past depression was 27.1% (95% CI: 22.5-32.3%); for current dysthymia: 4.5% (95% CI: 2.7-7.4%); for prewar and past dysthymia: 1% (95% CI: 0.3-2.8%), all with no significant differences detected across all demographic variables. In this retrospective study on a sample of Syrian refugees who fled their country after the war, we found a substantial emergence of depressive disorders with no meaningful correlation with the level of religiosity.

In total 34 ewes of two breeds and crosbreeds Tsigai (14 heads and Improved Valachian (20 heads with Lacaune were tested. Two weeks after lamb weaning the ewes were milked in parallel milking parlour (1x16 stalls under shelter. On the last evening milking (first experimental milking, EB before relocation of flock to another parlour, and during next three continuous evening milkings (E0 - second, E1 - third and E2 - fourth milking of exp. after relocation the milk flow kinetics were measured using electronic collection jar. On day E0 after morning milking the flock was moved on a pasture and milked in other parlour (1x24-stalls. During E0 we recorded a significant decrease of total milk yield in comparison with EB (0.527 ±0.04 and 0.647 ±0.04 L. Significant differences were also recorded in machine milk yield, machine stripping, milking time and in maximum milk flow rate. During E0 there was a higher number of nonbimodal and lower numbers of bimodal flow types. The response of ewe to E0 depended on its response to EB. Ewes with bimodal flow at EB responded more negatively to E0 than ewes with nonbimodal or plateau flow. During E2 there were significantly increased protein content and solids not fat in milk. Thus the treatment significantly influenced the milkability of ewes in a negative way, but more clear response was found out in ewes with bimodal flow response to machine milking before treatment. We could assume that relocation to other milking conditions caused only short-term changes in milk flow kinetic and milk yield. Normal 0 21 false false false SK X-NONE X-NONE

Full Text Available The objective of this work was to evaluate the reproductive performance of Santa Inês ewes fed a diet supplemented with protected fat. Intervals from lambing to first clinical estrus and to conception, conception rate, prolificacy, live weight and body condition were determined. After lambing, 60 ewes and their offsprings were weighted and randomly assigned to three treatments, based on age, body weight and number of born lambs. Treatments consisted of: control diet, or control diet plus 30 g of protected fat, from lambing to day 25 of post-lambing (Sup25, or to day 60 of post-lambing (Sup60. Out of 60 evaluated ewes, 93.3% returned to estrus, and 74.5% got pregnant, with 73.53% lambing rate and 196.5 days lambing interval. The average periods from lambing to first estrus were 32.4, 27.2 and 35.5 days for ewes fed the control diet, Sup25, and Sup60, respectively. The intervals from lambing to conception were 45.2, 46.5 and 45.2 days, and the supplemented diets did not show differences in comparison to the control diet. Supplementation with protected fat to well-nourished Santa Inês ewes does not improve their reproductive performance.

We aimed to investigate single nucleotide polymorphisms (SNPs) in the EWS gene breaking region in order to analyze Ewing's sarcoma susceptibility. The SNPs were investigated in a healthy subject population and in Ewing's sarcoma patients from Southern Brazil. Genotyping was performed by TaqMan® assay for allelic discrimination using Real-Time PCR. The analysis of incidence of SNPs or different SNP-arrangements revealed a higher presence of homozygote TT-rs4820804 in Ewing's sarcoma patients (p=0.02; Chi Square Test). About 300 bp from the rs4820804 SNP lies a palindromic hexamer (5'-GCTAGC-3') and three nucleotides (GTC), which were previously identified to be in close vicinity of the breakpoint junction in both EWS and FLI1 genes. This DNA segment surrounding the rs4820804 SNP is likely to indicate a breakpoint region. If the T-rs4820804 allele predisposes a DNA fragment to breakage, homozygotes (TT-rs4820804) would have double the chance of having a chromosome break, increasing the chances for a translocation to occur. In conclusion, the TT-rs4820804 EWS genotype can be associated with Ewing's sarcoma and the SNP rs4820804 can be a candidate marker to understand Ewing's sarcoma susceptibility.

Full Text Available The objective of this study was to investigate the effects of partial replacement of wheat hay with sun-dried (SOC or acid-treated SOC (ASOC olive cake on nutrient intake and performance of Awassi lambs. An additional objective was to study the effects of acid treatment of olive cake (OC on its chemical composition and nutritive value. On DM basis, sun-drying of OC did not dramatically affect its chemical composition. On the other hand, treating SOC with phosphoric acid decreased (p<0.05 SOC contents of neutral detergent fiber. Twenty seven male lambs (17.6±0.75 kg body weight individually housed in shaded pens were randomly assigned to one of three dietary treatments (9 lambs/treatment. Dietary treatments were formulated to be isocaloric and isonitrogenous by replacing 50% of wheat hay in the control diet (CTL with SOC or ASOC and to meet all nutrient requirements. Dietary treatments had no effects on nutrient intake or digestibility except for ether extract. Lambs fed the SOC diet had (p = 0.05 faster growth rate, greater final body weight, and greater total body weight gain in comparison with the CTL diet, but not different from the ASOC diet. Additionally, lambs fed the SOC diet had greater (p = 0.03 hot and cold carcass weights than the ASOC diet, but not different from the CTL diet. However, feed conversion ratios and dressing percentages were similar among dietary treatments. In conclusion, replacing half of dietary wheat hay with SOC improved performance of Awassi lambs with no detrimental effects on nutrients intake or digestibility. No further improvements in the nutritive value of SOC and lambs performance were detected when SOC was treated with acid.

The number of 239 (137 in year 2009 and 102 in 2010) pregnant ewes with the same age and average live body weight were used in the present study. The experimental does reared under same conditions during May to September in 2009 and August to December in 2010, respectively. The available data for each animal were obtained from the recodes. The classified of breeds and total numbers used in this study were (Ossimi =49, Barki =47, Rahmani =60 and crossbred =83). Season of lambing started in October to November in 2009 and January and February in 2010. After parturition, the does were classified according to litter size into two groups. The ewes in the 1st and 2nd groups were labor single or twins lamb, respectively. The results showed that progressed pregnancy stages related with decreases in concentrations of immunity function (total proteins, albumin and globulin), cholesterol, glucose and calcium in serum of pregnant ewes. On the other hand, enzymes activities of liver functions (GOT, GPT and γGT), creatinine, triglycerides and phosphorus increased in serum of pregnant ewes with progressed pregnancy stages. Progesterone and parathormone concentrations showed opposite trends to those obtained levels with progressed pregnancy stages. Comparison between ewes conceived single or twins fetuses showed that most blood components values are related with survivability of lambs. In ewes conceived single fetus recorded higher values of total proteins, albumin, globulin, glucose and calcium than ewes conceived twins fetuses. On the other hand, GOT, GPT and γGT, cholesterol, triglycerides, creatinine, urea and phosphorus concentrations were lower in ewes conceived single fetus than in ewes conceived twins fetuses. On the opposite, progesterone and parathormone concentrations were lower in single than in twins fetuses

The aim of thus study is to investigate the risk of exposure to Uranium and its radioactive products in Syrian phosphate miners (Khneefees and Al-sharkia). Chromosomal aberrations have been estimated in peripheral blood lymphocytes of miners using whole blood cultures `in vitro` for 48 hrs. The control group has been the normal population in damascus 180 km far from khneefees and 210 km from Al-sharkia. Our results have shown a significant difference between the miners and our control group; however there was no significant difference between the two miners groups. These results show an accumulative biological effect induced by environmental contamination in the Syrian phosphate mines. 3 figs., 3 tabs.

Full Text Available Twenty-nine fetuses (11 fetuses from 9 non-superovulated ewes and 18 fetuses from 8 superovulated ewes were used to study the effect of superovulation of ewes prior to mating on fetal weight, fetal length, the length of the body and limbs, chest circumference, weights of the body, head, neck, limb, and viscera. Superovulated ewes, though with a higher litter size, had a greater fetal growth as was indicated by the greater fetal weight and length, the length and weight of the body and limb on day 49 of pregnancy. On day 105 of pregnancy, superovulated ewes with multiple fetuses (≥3 had similar fetal growth than nonsuperovulated ewes with single and twin fetuses. However, superovulated ewes with a single fetus had greater fetal growth as was shown by the greater fetal weight and length, the length of the body and limbs, chest circumference, and weight of the body, limb, and viscera when compared to those non-superovulated ewes with a single or twin fetuses. The results of the experiment suggested that superovulation of ewes prior to mating could be used to improve fetal prenatal growth during pregnancy

Full Text Available The aim of this study was to determine the effect of dietary selenium supplementation (organic, inorganic of high pregnant ewes on the production traits of lambs, the concentration of selenium in the blood of ewes and their lambs, indicators of antioxidant status in the blood of ewes and their lambs, the metabolic profile of ewes and their lambs and concentrations of thyroid hormones. Ewes were in the last third of pregnancy, the average age of four years, healthy and in good condition, divided into three groups of 10 animals. The research lasted 4 months respectively, 2 months with ewes during high pregnancy, 2 months with ewes during lactation and on their lambs during suckling period. Ewes ration from control group one was composed from 300 g/day/animal feed mixture without addition of selenium and 150 g/day/animal barley and alfalfa hay that they had ad libitum. Feed mixture from second group of ewes was supplemented with 0.3 mg/kg organic form of selenium (Sel-Plex®, and feed mixture from third group with the same amount inorganic form of selenium (sodium selenite. Selenium supplementation of ewes feed mixture did not significantly influence on the production traits of their lambs postpartum. Selenium supplementation of ewes and their lambs had influence on a significant (P<0.01; P<0.05 increase in the concentration of selenium, GSH-Px and SOD in whole blood compared to control group of ewes. Organic selenium supplement had a more significant impact on the increase in concentration of selenium and GSH-Px in the blood. In the ewes and lambs blood was determined decrease of MDA with increasing concentrations of selenium in the blood. Generally, the selenium supplementation led to an increase (P<0.05 in the number of WBC and lymphocytes in the blood of ewes and lambs. Also, the increase in the number of RBC, HGB content and MCV in lambs and MCH as well as MCHC in ewes that had a selenium supplement in feed mixture were determined

Recent reports have suggested that child marriage among Syrians may be increasing as a result of displacement and conflict. This study sought to gather qualitative data about the factors that promote child marriage practices among Syrian refugees in Al Marj area in the Bekaa valley, Lebanon, where the majority of Syrian refugees have settled in Lebanon. The second aim of this study was to generate recommendations on how to mitigate the drivers and consequences of child marriage practices based on the findings. Eight focus group discussions were conducted separately with married and unmarried young women and mothers and fathers of married and unmarried women. Furthermore, researchers conducted 11 key informant interviews with service providers and stakeholders to understand how conflict and displacement influenced marriage practices of Syrian refugees in Al Marj community. Although child marriage was a common practice in pre-conflict Syria, new factors seem to contribute to a higher risk of child marriage among Syrian refugees in Lebanon. Respondents cited conflict- and displacement-related safety issues and feeling of insecurity, the worsening of economic conditions, and disrupted education for adolescent women as driving factors. Service providers, young women, and parents also reported changes in some marriage practices, including a shorter engagement period, lower bride price, change in cousin marriage practices, and a reduced age at marriage. Recommendations for interventions to mitigate the drivers of child marriage and its negative consequences should be built on a clear understanding of the local refugee context and the drivers of child marriage in refugee settings. Interventions should involve multiple stakeholders, they should be adjusted to target each specific context, age group and marital status. For these interventions to be effective, they should be addressed concurrently, and they should be delivered in a culturally sensitive and practical manner.

Sexual activity in sheep is under photoperiodic control, which is the main environmental factor responsible for the seasonality of reproduction. However, other natural environmental factors such as presence of conspecifics can slightly influence the timing of onset and offset of the breeding season. In goats, we have found that the continuous presence of bucks that were rendered sexually active out of season by previous exposure to long days, prevented goats from displaying seasonal anestrus, which suggests that the relative contribution of photoperiod in controlling seasonal anestrus should be reevaluated in small ruminant species. The aim of this study was to assess whether the presence of sexually active rams that had been stimulated by artificial photoperiod and melatonin implants, reduces seasonal anestrus in sheep, by prolonging ovulatory activity in spring. Ewes were assigned to one of two groups (n = 16 and 15), which were housed in two separate barns, and kept in contact, either with the treated or the control rams between March and July. Vasectomized rams were either exposed to 2 months of long days followed by the insertion of three subcutaneous melatonin implants (treated rams, n = 8), or exposed to natural light conditions (control rams, n = 2). Estrus was monitored daily, and weekly plasma progesterone analyses indicated ovulatory activity. Ewes that were exposed to treated rams exhibited a higher proportion of monthly estrus than ewes exposed to the control rams (P ewes (one ewe was not considered because of the presence of persistent CL) exposed to stimulated rams exhibited estrous behavior in a cyclic manner. In contrast, all ewes exposed to control rams stopped estrous activity for a period of time during the study, such that this group exhibited a significantly longer anestrous season (mean ± standard error of the mean 89 ± 9 days) than did the ewes housed with treated rams (26 ± 10 days; P ewes housed with treated rams, 13 of

Background: Some former retrospective studies have suggested that patients with Ewing's sarcoma might have a very high risk for developing secondary sarcomas if treated with radiotherapy. We have evaluated the risk of second malignancies (SM) in patients treated in the German Cooperative Ewing's Sarcoma Studies CESS 81 and CESS 86. Materials and methods: From January 1981 through June 1991, a total number of 674 patients was registered in the two multicentric Ewing's sarcoma trials CESS 81 (1981 through 1985) and CESS 86 (1986 through June 1991). The systemic treatment consisted in both studies of a four-drug-chemotherapy (VACA= vincristine, actinomycin D, cyclophosphamide and adriamycin; or VAIA= vincristine, actinomycin D, ifosfamide and adriamycin) and a total number of four courses, each lasting nine weeks, was recommended by the protocol. Local therapy was either complete surgery or surgery plus postoperative radiotherapy with 36-46Gy or definitive radiotherapy with 46 to 60Gy. The median follow-up at the time of this analysis was 7 years, the maximum follow-up 16 years. Results: Eight patients developed a SM, 4 were acute myelogenic leucemias, three sarcomas and one benign neurinoma. One of the sarcomas was considered as radiation-induced because of its location in the former radiation field. The interval between diagnosis of Ewing's sarcoma and the diagnosis of the SM was 17 to 78 months for the four AMLs and 82 to 136 months for the three sarcomas. All solid second tumors occurred in irradiated patients. The cumulative risk of a SM is given in table 1. Three patients (all with AML) died of their SM, the other five were salvage by subsequent treatment and are in clinical remission with a median follow-up of 1 to 10 years. Conclusions: The risk of leukemia after treatment for Ewing's sarcoma is probably low in the range of 1-2% or less and accounts for about 1% of all deaths. There was no risk of solid tumors in surgically treated patients. Irradiated

Ewing's sarcoma belongs to a spectrum of neoplastic diseases known as Ewing's family of tumors. This family of tumors is usually seen in osseous sites. Ewing's sarcoma of the cervix is extremely rare, with only 18 cases reported in the English literature. The immunohistochemical profile of Ewing's sarcoma overlaps with other malignancies like small cell carcinoma. The rarity and complex pathologic picture of Ewing's sarcoma of the cervix creates the potential for misdiagnosis. Hence, we believe this case needs to be reported to add to the available literature. A 49-year-old white Caucasian woman presented with vaginal bleeding. A pelvic examination revealed a cystic lesion arising from her cervix. Examination of a biopsy specimen revealed a poorly differentiated neoplasm, with sheets of small hyperchromatic cells, staining weakly for neuroendocrine markers. She was diagnosed with small cell carcinoma and started on concurrent chemotherapy and radiation. However, additional positive immunostaining for CD99 was strongly suggestive of Ewing's sarcoma. Fluorescence in situ hybridization revealed ESWR1 gene rearrangement, confirming Ewing's sarcoma. Our patient underwent surgery, which confirmed stage IIB Ewing's sarcoma. She received adjuvant chemotherapy but died from progressive metastatic disease after four cycles. With early diagnosis and appropriate treatment, Ewing's sarcoma of the cervix can be a potentially curable disease. However, owing to overlapping clinical and histopathological features, the diagnosis poses a challenge to oncologists and pathologists. This article guides pathologists to consider Ewing's sarcoma in the differential diagnosis of small cell carcinoma with weak staining for neuroendocrine markers. This literature review will benefit oncologists encountering this rare entity.

Norm waste in oil and gas industry: The Syrian experience

International Nuclear Information System (INIS)

Al-Masri, M.S.; Suman, H.

2001-01-01

This paper describes the Syrian experience in respect to Naturally Occurring Radioactive Materials (NORM) waste in Syrian oil and gas industry. NORM can be concentrated and accumulated in tubing and surface equipment of oil and gas production lines in the form of scale and sludge. NORM waste (scale, sludge, production water) is therefore generated during cleaning, physical or chemical treatment of streams. Uncontrolled disposal of this type of waste could lead to environmental pollution, and thus eventually to exposure of members of the public. The presence of NORM in Syrian oil fields has been recognized since 1987 and AECS has initiated several studies, in cooperation with oil companies, to manage such type of waste. Three categories of NORM waste in Syrian oil fields were identified. Firstly, hard scales from either decontamination of contaminated equipment and tubular using high-pressure water systems or mechanical cleaning at site are considered to contain the highest levels of radium isotopes ( 226 Ra, 228 Ra, 224 Ra). Secondly, sludge wastes are generated with large amount but low levels of radium isotopes were found. Thirdly, contaminated soil with 226 Ra as a result of uncontrolled disposal of production water was also considered as NORM waste. The first waste type (scale) is stored in Standard storage barrels in a controlled area; the number of barrels is increasing with time. High levels of radium isotopes were found in these scales. The options for disposal of these wastes are still under investigations; one of the most predominant thinking is the re-injection into abundant wells. For sludge waste, plastic lined disposal pits were constructed in each area for temporary storage. Moreover, big gas power stations have been built and operated since the last ten years. Maintenance operations for these stations produce tens of tones of scales containing radon daughters, 210 Pb and 210 Po with relatively high concentrations. The common practice used to dispose

Selection for high levels of prolificacy has allowed substantial improvements in the production efficiency of New Zealand (NZ) sheep farms, but the consequences on ewe lifetime performance are mostly unknown. In this study, the relationship between the level of prolificacy early in ewes' productive lives and their probability to survive later (i.e. stayability) was evaluated in two contrasting NZ flock environments. Records were obtained from 6605 ewes from four ram breeder flocks representing either a moderate (n=2) or a highly variable (n=2) nutritional environment. All ewes lambed for the first time at 2 years of age and were mated the following year. The number of lambs born during the first 2 years of productive life (NLB2-3) was used as a measure of early prolificacy. Effects of NLB2-3 on stayability to 4, 5, 6, 7 and 8 years old were analysed using logistic regression. Curvilinear effects (logit-transformed) were detected (Pewe stayability was reduced when the proportion of the litter that survived from birth to weaning (i.e. ewe rearing ability) was submaximal during the early productive life. High prolific ewes had a low rearing ability whatever the environment whereas the rearing ability of lowly prolific ewes was apparently more sensitive to the nutritional environment. The poor maternal performance of ewes with low levels of NLB2-3 led to a premature culling by breeders whereas the high early reproductive effort associated with high levels of NLB2-3 seemed to be at the cost of ewes' survival, even in the moderate flock environment. In conclusion, the flock environment influenced the level of early prolificacy beyond which ewe longevity was reduced. It is suggested that further selection for high and early prolificacy in NZ flocks is likely to impair ewes' lifetime productivity.

More than one hundred different food stuffs (meat, vegetables cereals, seafood,..) have been collected during 1998, 1999 and 2000 and analyzed for radioactivity as part of the National Food Monitoring Program in Syria. Results have shown that most of the observed concentrations were within the range of the worldwide values with the exception of relatively high levels of 210 Po being observed in fish, vegetables, mushrooms, herbs and flowers. The daily intakes of the radionuclides studied have been evaluated. Relatively high values, in comparison with some countries, were found for 210 Po (1.9 Bq/day). This is due to high content of 210 Po in wheat (2.3 Bq/kg) consumed by Syrians, the daily consumption of wheat by Syrians is about 526 g. In addition, natural and artificial radionuclides in some manufactured food of Syrian infant and their intake rates have been determined. Seventeen manufactured food and eleven types of canned milk were collected from the local market and their radioactivity analyzed. 210 Po activity concentration varied between 0.38 and 2.89 Bq/kg dry wt. in canned milk while the highest concentration in infant food was found to be 1.69 Bq/kg dry wt. Other radionuclide concentrations were below the limit of detection of 3 Bq/kg dry wt. and 4 Bq/kg dry wt. for 22' 6Ra and 228 Ra, respectively, while uranium concentration varied between 2.2 and 10.5 μg/kg dry wt. in milk samples and 0.78-6.0 μg/kg dry wt. in other food samples.

The pharmacokinetics of lidocaine were studied in nonpregnant and pregnant ewes. The maternal femoral vessels were cannulated and, on the day of study, the urinary bladder was catheterized. Lidocaine HCl, 4-5 mg/kg, was administered by IV injection over 60 seconds. Serial samples of arterial blood and urine were collected over 4 hours, and drug concentrations were determined using a gas chromatographic technique. The volume of the central compartment was greater in pregnant than in nonpregnant ewes (1.51 +/- 0.20 vs. 0.96 +/- 0.16 L/kg) as was the volume of distribution at steady state (Vdss): 3.24 +/- 0.40 vs. 1.88 +/- 0.32 L/kg. The volume of distribution during the terminal exponential phase of drug elimination (Vd beta) and total clearance of lidocaine (Cl) were also higher in pregnant animals: 4.17 +/- 0.50 L/kg and 99.6 +/- 8.5 ml.min-1.kg-1, respectively; compared to 2.46 +/- 0.48 L/kg and 44.1 +/- 6.5 ml.min-1.kg-1, in nonpregnant ewes. However, the balance between these changes in Vd beta and Cl did not result in a significant difference in the elimination half-life of lidocaine (38.1 +/- 2.1 minutes in nonpregnant and 31.9 +/- 3.0 minutes in pregnant ewes). If these data are applicable to humans, the risk of drug accumulation after repeated administration of lidocaine is no greater in pregnant than in nonpregnant patients.

The Ewing's sarcoma comprises approximately less than 10 percent of malignant bone tumors and 5 percent of all bone tumors, occurs in almost all bones of the body, and presents a widely divergent roentgenographic manifestations. The tarsal bones are involved only 2 percent in the Ewing's sarcoma. Two cases experienced by authors and ten cases published in literatures of Ewing's sarcoma of the tarsal bone were analyzed retrospectively. The result were as follows: 1. Of the tarsal bones, the calcaneus was 7 cases, the talus 4 cases, cuneiform 1 case. 2. Female was affected more commonly than male, the ratio being 4 to 1 in the tarsal bones. 3. About sixty percent of total cases in the tarsal bones had evidence of diffuse sclerotic pattern. All the cases of the talus had evidence of diffuse sclerotic pattern. 4. The diseases to be considered in differential diagnosis are as follows: avascular necrosis, tuberculous osteomyelitis, osteosarcoma, and pyogenic osteomyelitis. 5. The diffuse sclerosis radiographically showed a close relation with dead bone resulting from avascular necrosis due to tumor infiltration histologically. Periosteal reactive new bone and osteoid deposition on the dead bone were also correlated with diffuse sclerosis. 6. Because it is difficult to differentiate sclerotic lesions in the tarsal bones by radiographic methods alone, all such lesions should be subject to biopsy as early as possible

The study was conducted to assess the health needs of urban refugees living in İstanbul. A mixed methods approach was adopted to interview Syrian women from households, doctors, decision makers and NGO representatives. The data were collected between June and October 2015. The main challenges were the cost of living in İstanbul, increased rent and language barrier. Almost half (49.6%) of the interviewed women did not know about free health care rights for Syrians. In the last 30 days preceding the interview, 58.6% of the participants sought health care primarily through state hospitals, primary health care centres and pharmacies. The participants had difficulty in accessing health care due to the language barrier and a lack of knowledge of the Turkish health care system. Waiting time at hospitals and negative attitudes of health care staff reduced satisfaction in these services. In relation to life in Turkey, the main issues for Syrian refugees were not directly related to health. They have been given the right to access health care, although had many difficulties in understanding and accessing services in a crowded city.

The Syrian public health and humanitarian crisis: A 'displacement' in global governance?

Science.gov (United States)

Akbarzada, Sumaira; Mackey, Tim K

2018-07-01

Ongoing failure by the international community to resolve the Syrian conflict has led to destruction of critical infrastructure. This includes the collapse of the Syrian health system, leaving millions of internally displaced persons (IDPs) in urgent need of healthcare services. As the conflict intensifies, IDP populations are suffering from infectious and non-communicable disease risks, poor maternal and child health outcomes, trauma, and mental health issues, while healthcare workers continually exit the country. Healthcare workers who remain face significant challenges, including systematic attacks on healthcare facilities and conditions that severely inhibit healthcare delivery and assistance. Within this conflict-driven public health crisis, the most susceptible population is arguably the IDP. Though the fundamental 'right to health' is a recognised international legal principle, its application is inadequate due to limited recognition by the UN Security Council and stymied global governance by the broader international community. These factors have also negatively impacted other vulnerable groups other than IDPs, such as refugees and ethnic minorities, who may or may not be displaced. Hence, this article reviews the current Syrian conflict, assesses challenges with local and global governance for IDPs, and explores potential governance solutions needed to address this health and humanitarian crisis.

The aim of this study was to determine whether arginine (Arg) supplementation of malnourished ewes affects the expression of key NO/PGC-1α signaling pathway genes in the ovary. On Day 6-15 of the estrous cycle, 24 multiparous Hu sheep (BW = 43.56 ± 1.53 kg) were randomly assigned to three groups: control group (CG; n = 6), restriction group (RG; n = 9) and l-arginine group (AG; n = 9), and administered Arg treatment (or vehicle) three times per day. The ewes were slaughtered at the end of treatment, and blood samples and ovaries were collected for analysis. The results of our analyses showed that both short-term feed-restriction and/or supplementation with L-Arg-HCl affected the number of different size follicles observed in the ovary, and the relative day of estrus behavior initiation of ewes. Specifically, the relative day of estrus behavior initiation was significantly advanced in AG compared with that in RG ewes (P ewes. RG ewes exhibited a higher proportion of ≤2 mm (P 5 mm follicles than did CG ewes (P ewes. Furthermore, the expression of eNOS, nNOS, iNOS, PDE5A, PDE9A, PRKG2, and PPARGC1A varied significantly among the treatment groups (P ewes (P ewes (P ewes (P ewes (P ewes (P ewes. In conclusion, the results of the present study indicate that feed-restriction negatively affects follicular development, and that Arg-supplementation may modulate the expression of key NO/PGC-1α signaling pathway genes in the ovary and thereby accelerate ovulatory processes and the estrous rate. Elucidation of mechanisms underlying these effects of Arg on gene expression in the ewe ovary requires further investigation. Copyright © 2017 Elsevier Inc. All rights reserved.

Alterations in DNA methylation patterns are a hallmark of malignancy. However, the majority of epigenetic studies of Ewing's sarcoma have focused on the analysis of only a few candidate genes. Comprehensive studies are thus lacking and are required. The aim of the present study was to identify novel methylation markers in Ewing's sarcoma using microarray analysis. The current study reports the microarray-based DNA methylation study of 1,505 CpG sites of 807 cancer-related genes from 69 Ewing's sarcoma samples. The Illumina GoldenGate Methylation Cancer Panel I microarray was used, and with the appropriate controls (n=14), a total of 92 hypermethylated genes were identified in the Ewing's sarcoma samples. The majority of the hypermethylated genes were associated with cell adhesion, cell regulation, development and signal transduction. The overall methylation mean values were compared between patients who survived and those that did not. The overall methylation mean was significantly higher in the patients who did not survive (0.25±0.03) than in those who did (0.22±0.05) (P=0.0322). However, the overall methylation mean was not found to significantly correlate with age, gender or tumor location. GDF10 , OSM , APC and HOXA11 were the most significant differentially-methylated genes, however, their methylation levels were not found to significantly correlate with the survival rate. The DNA methylation profile of Ewing's sarcoma was characterized and 92 genes that were significantly hypermethylated were detected. A trend towards a more aggressive behavior was identified in the methylated group. The results of this study indicated that methylation may be significant in the development of Ewing's sarcoma.

We aimed to compare the clinical characteristics and pregnancy outcomes in women who are Syrian refugees and Turkish women who are non-refugees at a maternity center in Istanbul, Turkey. A total of 600 singleton pregnancies who delivered at Sisli Hamidiye Etfal Training and Research Hospital were included in the study. Demographic data, obstetrical history, clinical findings, obstetrical and neonatal outcomes were compared between 300 Syrian refugees and 300 control patients. The Syrian refugee patients were significantly younger than Turkish patients. The percentage of adolescents aged 12-19 years were significantly higher in the Syrian patients (14.3 vs. 5.3 %, p refugee patients had no antenatal care. However, this ratio was only 7.7 % for the control group (p refugee control patients, refugee women in our study had poor antenatal care but no adverse perinatal outcomes were observed. Further larger multicenter studies may provide more convincing data about obstetric outcomes in the Syrian refugee population as well as adolescent pregnancies in this population.

2012-01-01

Ewing's sarcoma is a highly malignant tumor that metastasizes rapidly and is thus associated with a low survival rate. The intensification of chemotherapy has been shown to improve the overall survival of patients with Ewing's sarcoma. However, intensified chemotherapy can lead to increased toxicity or even the development of secondary malignancies. The stratification of patients with Ewing's sarcoma into "good" and "poor" responders may help guide the administration of progressively more intensified chemotherapy. Thus, an accurate assessment of the chemotherapeutic response, as well as the extent of chemotherapy-induced tumor necrosis, is critical for avoiding potential treatment-related complications in these patients. This paper reviews the methods currently used to evaluate chemotherapeutic response in Ewing's sarcoma, focusing specifically on histopathologic and imaging analyses, and discusses novel therapies and imaging methods that may help improve the overall survival of these patients.

The present study aims to elucidate the effect of palm and olive oil by-products adding to rations on production and reproductive performance of Rahmani and Osimi female sheep. After weaning, Rahmani and Osimi ewe lambs (24 for each) of similar birth type were identified to compare between two rations containing hard fatty acids (HFA) or olive cake (OC) on sexual puberty and fertility of two breeds. The lambs of both breed were randomly divided into three groups: the first group is considered control and received ration which contained concentrate feed mixture (CFM). The second group nourished (OC) consisted of CFM +HFA and the third group nourished (HFA) composed of CFM +OC. The CFM was offered as basal ration to all experimental lambs. Body weight, functions of the liver, kidney, thyroid and progesterone hormones at puberty, and the fertility traits were assayed in the two breeds of ewes. The average body weight of female lambs was higher (P<0.05) with OC than HFA. Female lambs supplied OC reached puberty faster and their thyroid and sexual hormones (progesterone) have been developed earlier than ewe lambs given HFA and those in the control group. Age at puberty and progesterone level in both Rahmani and Osimi ewe lambs were better in ewes fed on OC , than other two groups. The fertility (%) from total ewe lambs and birth weight in ewe lambs fed on OC were higher than ewes fed on HFA and the control. It may be concluded that feeding ewe lambs on diet containing HFA from weaning had positive effects on age at puberty, reproductive fertility and prolificacy

Primary Vaginal Extraosseous Ewing Sarcoma/Primitive Neuroectodermal Tumor with Cranial Metastasis

Full Text Available Extraosseous Ewing sarcoma is now regarded as a member of the Ewing sarcoma/primitive neuroectodermal tumor (PNET family. It typically involves the soft tissues of the chest wall, pelvis, paravertebral region, abdominal wall, retroperitoneal region and extremities of children, adolescents and young adults, but it seldom occurs in the female genital tract. We report an extremely rare case of retrospective diagnosis of vaginal extraosseous Ewing sarcoma/PNET which metastasized to the right frontoparietal scalp, skull, and dura. Surgical resection, followed by adjuvant radiotherapy and chemotherapy resulted in a favourable clinical outcome. Both the vaginal and head tumors had similar light microscopic features supporting the diagnosis.

Ewe efficiency has traditionally been defined as the ratio of litter weight to ewe weight; given the statistical properties of ratio traits, an alternative strategy is proposed in the present study. The concept of using the deviation in performance of an animal from the population norm has grown in popularity as a measure of animal-level efficiency. The objective of the present study was to define novel measures of efficiency for sheep which considers the combined weight of a litter of lambs relative to the weight of their dam, and vice versa. Two novel traits, representing the deviation in total litter weight at 40 d (DEV40L) or weaning (DEVweanL), was calculated from the residuals of a statistical model, with litter weight as the dependent variable and with the fixed effects of litter rearing size, contemporary group and ewe weight. The deviation in ewe weight at 40 d post lambing (DEV40E) or weaning (DEVweanE) was derived using a similar approach but with ewe weight and litter weight interchanged as the dependent variable. Variance components for each trait were estimated by first deriving the litter or ewe weight deviation phenotype and subsequently estimating the variance components. The phenotypic SD in DEV40L and DEVweanL was 8.46 kg and 15.37 kg, respectively; the mean litter weight at 40 d and weaning was 30.97 kg and 47.68 kg, respectively. The genetic SD and heritability for DEV40L was 2.65 kg and 0.12, respectively. For DEVweanL, the genetic SD and heritability was 4.94 kg and 0.13, respectively. The average ewe weight at 40 d post lambing and at weaning was 66.43 kg and 66.87 kg, respectively. The genetic SD and heritability for DEV40E was 4.33 kg and 0.24. The heritability estimated for DEVweanE was 0.31. The traits derived in the present study may be useful for phenotypic benchmarking of ewes within flock on performance but also for benchmarking flocks against each other; furthermore the extent of genetic variability in all traits, coupled with the

Ewe productivity (i.e., total number or weight of lambs weaned per breeding ewe) is a key indicator of lamb production efficiency. This study compared various measures of ewe productivity and ewe and lamb performance among ewes of 3 breed types mated to rams of 4 terminal-sire breed types in an extensive rangeland production system. Purebred Rambouillet ( = 212), purebred Polypay ( = 236), and crossbred Romanov-White Dorper × Rambouillet (RW-RA; = 231) ewes were produced from locally adapted Polypay and Rambouillet ewes and then annually mated to Columbia, Suffolk, Columbia × Suffolk, or Suffolk × Columbia sires for up to 4 yr, beginning at 1 yr of age. The cumulative number and weight of lambs weaned through 4 yr were greater for RW-RA (5.9 lambs and 153 kg, respectively) and Polypay ewes (4.9 lambs and 123 kg, respectively) than for Rambouillet ewes (2.9 lambs and 99 kg, respectively) and also were greater for RW-RA ewes than for Polypay ewes (all ewes, compared with Rambouillet ewes, was driven by greater lambing rates (ewes lambing per ewe exposed) as ewe lambs (87 and 77 vs. 31%, respectively; ewe lambs (1.3, 1.3, and 1.0, respectively) and adult ewes (2.1, 2.0, and 1.6, respectively). The RW-RA ewes also had greater longevity ( ewes. Lamb BW at birth and weaning in adult ewes favored less-prolific Rambouillet ewes ( ewe breed types were small and not significant ( = 0.08). Effects of sire breed type on measures of cumulative ewe productivity were not significant ( > 0.74), but Suffolk-sired lambs had the heaviest adjusted birth weights ( = 0.01) and Columbia-sired lambs tended to have the lightest adjusted weaning weights ( = 0.12). Combined effects of heterosis and additive breed effects were associated with greater lambing rates in ewe lambs, larger litters at all ages, and substantially greater number and weight of lambs weaned for Polypay and RW-RA ewes than for Rambouillet ewes.

Effect of supplementing a diet, in an attempt to enhance reproduction, with monensin sodium and Saccharomyces cerevisiae yeast on reproductive performance was investigated during the breeding season using 44 Ghezel ewes (body weight 56.97±7.47kg, age 2-5 years and body condition score (BCS) 2.5) which were allocated randomly in equal numbers to the four dietary treatments as follows: 1) Basal diet plus supplemental feed (450g/ewe/d) plus monensin sodium (30mg/ewe/d) (MS); 2) Basal diet plus supplemental feed (450 g/ewe/d) plus Saccharomyces cerevisiae yeast (4×10 9 CFU/ewe/d) (SC); 3) Basal diet plus supplemental feed (450g/ewe/d) (FG); 4) Basal diet (only grazing on pasture, Control; G). Estrous synchronization of all ewes was done using controlled internal drug release (CIDR) and all ewes were mated with purebred Ghezel rams after CIDR removal. The results indicated that MS and SC treatments with 15 lambs had greater number of lambs than ewes of the other two treatment groups. Ewes in MS group with 50% twining rate had the greatest value followed by the FG, SC and G treatment groups (Pewes in MS and SC groups were heavier in weight than those in FG and G treatments (Pewes in MS and SC groups had greater concentrations of 17β-estradiol (E2), progesterone (P4), blood urea nitrogen (Pewes of the other groups. These results indicated that using a diet for enhancing reproduction, including monensin sodium and Saccharomyces cerevisiae yeast in the breeding season could have beneficial effects on reproductive performance of Ghezel ewes.

The United Nations has declared the Syrian conflict, with more than 50% of Syria’s population currently displaced, as the worst humanitarian crisis of the twenty-first century. The Syrian conflict has led to a collapse of infrastructure, including access to critical and lifesaving healthcare services. Women and children account for approximately 75% of internally displaced Syrians and refugees. This population is also particularly vulnerable to poor health outcomes, a condition worsened by lack of access to maternal and child health services. In response to this crisis, a partnership of Saudi and Syrian physicians established a non-profit healthcare facility named the Brotherhood Medical Center (BMC) to serve women and children within a safe area near the Syrian–Turkish border. The project began in September 2014 and was implemented in three phases of establishment, phased construction and formal launch and operation. Currently, the BMC is working at about 70% of its capacity and is run in partnership with the Syrian Expatriate Medical Association. Although there was strong initial support from donors, the BMC continues to face many financial and operational challenges, including difficulties in transferring money to Syria, shortage of medical supplies, and lack of qualified medical personnel. Despite these challenges, the BMC represents a critical model and an important case study of the challenges of delivering healthcare services to underserved populations during an ongoing conflict. However, more robust support from the international community is needed to ensure it continues its important health and humanitarian mission. PMID:29721489

Targeting the p53 Pathway in Ewing Sarcoma

Neilsen, Paul M.; Pishas, Kathleen I.; Callen, David F.; Thomas, David M.

2011-01-01

The p53 tumour suppressor plays a pivotal role in the prevention of oncogenic transformation. Cancers frequently evade the potent antitumour surveillance mechanisms of p53 through mutation of the TP53 gene, with approximately 50% of all human malignancies expressing dysfunctional, mutated p53 proteins. Interestingly, genetic lesions in the TP53 gene are only observed in 10% of Ewing Sarcomas, with the majority of these sarcomas expressing a functional wild-type p53. In addition, the p53 downstream signaling pathways and DNA-damage cell cycle checkpoints remain functionally intact in these sarcomas. This paper summarizes recent insights into the functional capabilities and regulation of p53 in Ewing Sarcoma, with a particular focus on the cross-talk between p53 and the EWS-FLI1 gene rearrangement frequently associated with this disease. The development of several activators of p53 is discussed, with recent evidence demonstrating the potential of small molecule p53 activators as a promising systemic therapeutic approach for the treatment of Ewing Sarcomas with wild-type p53.

Full Text Available 66 Pampinta breed ewes were studied during milking to evaluate the infection and the effect of gastrointestinal nematode on milk production sheep system. Naturally infected ewes on pasture were randomly allocated to two groups: TG, suppressively treated group every four weeks with levamisole and UG, untreated group. Faecal nematode egg counts and larval differentiation were conducted monthly. Successive groups of worm free tracer lambs were grazed with ewes and then slaughtered for worm counts. Test-day milk yield of individual ewes was recorded and ewe machine-milking period length (MPL were estimated. Faecal egg counts and tracer nematode numbers increased towards midsummer and declined sharply toward the end of the study. TG (188.0 ± 60 liters produced more (p < 0.066 milk liters than UG (171.9 ± 52.2 and TG had significantly more extended (p < 0.041 MPL than those of UG. The present study showed that dairy sheep were negatively affected by worms, even when exposed to short periods of high acute nematode (mainly Haemonchus contortus infection.

2015-12-01

The underlying theme of this study involved the evaluation of the dilatory effects of prostaglandin E2 on the ovine cervix and thus the assessment of its potential applicability to transcervical artificial insemination (TCAI) in ewes. A novel method of prostaglandin E2 administration (controlled slow-release vaginal inserts) was examined, and the practical implications of this approach including cervical penetrability and posttreatment pregnancy rates were evaluated. The Guelph method of TCAI was performed during the seasonal anestrus (n = 40) and the breeding season (n = 40) on multiparous Rideau Arcott × Polled Dorset ewes, with or without the pretreatment with Cervidil (for a duration of 12 hours or 24 hours before TCAI). Cervical penetration rates averaged 82.5% (66 of 80), and they varied neither (P > 0.05) between the two seasons nor between Cervidil-treated ewes and their respective controls. Cervidil priming significantly reduced the total time required for TCAI during the breeding season in comparison with controls (54 vs. 98 seconds), especially after the 24-hour exposure (38 vs. 108 seconds). The time taken to traverse the uterine cervix was negatively correlated (P ewes. Four out of 36 (11%) successfully penetrated ewes in the breeding season (three ewes allocated to the 12-hour control group and one ewe that had received Cervidil for 12 hours) became pregnant and carried the lambs to term. Vaginal mucus impedance at TCAI was significantly and positively correlated with the total time required to complete the procedure in cyclic ewes, and the negative correlation between vaginal mucus impedance and total time values at the time of controlled intravaginal drug release device removal approached to significance in anestrous ewes. The present results indicate a moderate benefit of using Cervidil for inducing cervical dilation before TCAI in ewes, mainly in the breeding season.

A total number of 136 pregnant ewes with the same age and parity were used in the present study. The experimental ewes reared during Arabic months or lunar months, from the 1st Gomady to Zol-hega, 1432 AH. The available data for each animal were obtained from the records of Sheep Farm, Project of Experimental Farms. Lambing season started at months, Shawal to Zol-hega. After lambing, the ewes were divided into three groups according to moon phases. Ewes in the 1st group laboured in new moon phase period. The ewes in the 2nd and the 3rd groups laboured in full and old moon phases, respectively. The study was conducted to determine the changes in the body functions and reproductive of pregnant ewes due to the effect of lunar cycle which causes the increase of births by up to 72% in the full moon phase. The results showed that, a significant increase in feed and water consumption, the activity of liver enzymes, concentration of cholesterol, triglyceride, kidney functions and also the hormone thyroxine and triiodothyronine was recorded during full moon, on the contrary, there was a significant decrease in the concentration of total protein, albumin, glucose, calcium, phosphorus and cortisol in the blood of pregnant ewes was recorded during full moon phases followed by new and old moon. On the other hand, reproductive traits including litter size at birth and weaning and mortality rate were recorded during different moon phases.

Hypoxia regulates gene expression via the transcription factor HIF (Hypoxia-Inducible Factor). Little is known regarding HIF expression and function in primary bone sarcomas. We describe HIF expression and phenotypic effects of hypoxia, hypoglycaemia and HIF in Ewing's sarcoma and osteosarcoma. HIF-1alpha and HIF-2alpha immunohistochemistry was performed on a Ewing's tumour tissue array. Ewing's sarcoma and osteosarcoma cell lines were assessed for HIF pathway induction by Western blot, luciferase assay and ELISA. Effects of hypoxia, hypoglycaemia and isoform-specific HIF siRNA were assessed on proliferation, apoptosis and migration. 17/56 Ewing's tumours were HIF-1alpha-positive, 15 HIF-2alpha-positive and 10 positive for HIF-1alpha and HIF-2alpha. Expression of HIF-1alpha and cleaved caspase 3 localised to necrotic areas. Hypoxia induced HIF-1alpha and HIF-2alpha in Ewing's and osteosarcoma cell lines while hypoglycaemia specifically induced HIF-2alpha in Ewing's. Downstream transcription was HIF-1alpha-dependent in Ewing's sarcoma, but regulated by both isoforms in osteosarcoma. In both cell types hypoglycaemia reduced cellular proliferation by >or= 45%, hypoxia increased apoptosis and HIF siRNA modulated hypoxic proliferation and migration. Co-localisation of HIF-1alpha and necrosis in Ewing's sarcoma suggests a role for hypoxia and/or hypoglycaemia in in vivo induction of HIF. In vitro data implicates hypoxia as the primary HIF stimulus in both Ewing's and osteosarcoma, driving effects on proliferation and apoptosis. These results provide a foundation from which to advance understanding of HIF function in the pathobiology of primary bone sarcomas.

Teladorsagiosis is a major production-limiting disease in ruminants in temperate regions throughout the world and one of the key interventions in the management of the disease is the prevention of pasture contamination with Teladorsagia circumcincta eggs by ewes during the periparturient relaxation in immunity which occurs in the period around lambing. Here, we describe the immunisation of twin-bearing ewes with a T. circumcincta recombinant subunit vaccine and the impact that vaccination has on their immune responses and shedding of parasite eggs during a continuous T. circumcincta challenge period spanning late gestation and lactation. In ewes which displayed a clear periparturient relaxation in immunity, vaccination resulted in a 45% reduction in mean cumulative faecal egg count (cFEC, p=0.027) compared to control (immunised with adjuvant only) ewes. Recombinant antigen-specific IgG and IgA, which bound each of the vaccine antigens, were detected in the serum of vaccinated ewes following each immunisation and in colostrum taken from vaccinated ewes post-partum whereas low levels of antigen-specific IgG were detected in serum and colostrum from control ewes. Antigen-specific IgG and IgA levels in blood collected within 48h of birth from lambs largely reflected those in the colostrum of their ewes. Copyright © 2016 The Authors. Published by Elsevier B.V.

To further substantiate this, the present study compared seasonal variation in oestrus behaviour and ovulation in two Greek breeds (Chios and Serres) maintained in the same environment. In 27 adult ewes of each breed, oestrus behaviour, the occurrence of ovulation and ovulation rate were monitored during 2 successive years by daily inspection by rams, weekly progesterone assay in circulating blood plasma and monthly ovarian laparoscopy. The periods of anoestrus (109 +/- 8 (wk) vs 178 +/- 5 d) and anovulation (63 +/- 8 vs 149 +/- 6 d) were significantly shorter (P duration of oestrus was also longer in Chios ewes (1.8 +/- 0.05 vs 1.5 +/- 0.06 d; P = 0.002). There were significant correlations between the duration of anovulatory periods of the 2 successive years in Chios (r = 0.43) but not Serres ewes. Ovulation rate was positively related to the onset of the sexual season in Serres but not in Chios ewes. The present data suggest that: i) the efficiency of Serres but not in Chios ewes. The present data suggest that: i) the efficiency of spring mating in these breeds is suboptimal since it is a period when the percentage of ewes exhibiting oestrus and ovulation as well as ovulation rate are limited, ii) owing to the large variation in seasonality within Chios ewes and to the good between year correlation in features of seasonality, selection against seasonality in Chios ewes could be worthwhile.

A nutritional strategy for increasing ovulation rate in Merino ewes mated in late spring-early summer was evaluated on two commercial farms. The strategy used the 'ram effect' to induce oestrus in seasonally anoestrus ewes and supplementary feeding of lupin grain six days prior to oestrus to increase ovulation rate. Ewes that had been isolated from rams for 6 weeks were exposed to vasectomised rams for 2 weeks and then mated to fertile rams for 6 weeks. Feeding 500 g lupins/head/day for 14 days commencing 12 days after the introduction of vasectomised rams, increased the number of ovulations from 126 to 146 per 100 ewes exposed to rams (P < 0.05). This increase was reflected in an improvement in fecundity (lambs born per ewe lambing; P < 0.05) but not fertility (ewes lambing per ewe mated to rams). Net reproductive performance (the product of fertility, fecundity and lamb survival) was increased by 11 lambs weaned per 100 ewes exposed to rams due to lupin supplementation at mating.

The aim of this study is to investigate the exposure risk to Uranium and its radioactive products in Syrian phosphate miners (Khneefees and Al-Sharkia). Chromosomal aberrations have been estimated in peripheral blood lymphocytes of miners using whole blood cultures 'in vitro' for 48 hrs. The control group has been the normal population in Damascus 180 km far from Khneefees and 210 Km from Al-Sharkia. Our results have shown a significant difference between the miners and our control group. However there was no significant difference between the two miners groups. These results show an accumulative biological effect induced by environmental contamination in the Syrian phosphate mines. (author). 21 refs., 8 figs., 5 tabs

Full Text Available ABSTRACT Profitability of sheep production depends on the reproductive response of ewes and growth of their lambs, which can be improved through the ram genotype. The aim of this study was to evaluate the reproductive response of Blackbelly (Bb, Pelibuey (Pb, Katahdin (Kat and Dorper (Dor ewes crossed with Damara (Dam and Dor rams and the growth of their offspring. To measure percentage of single and multiple lambings (MLP, 234 Bb, Pb, Kat and Dor ewes were used. To measure lamb growth, the offspring of 86 Bb x Pb (BbPb ewes and 73 Kat x Dor (KatDOR ewes were used. Four Dor x BbPb, six Dam x BbPb and six Dam x KatDor lambs were slaughtered for carcass assessment. MLP was analyzed with the CATMOD procedure considering the factors age and breed. Lamb growth data were analyzed with the MIXED procedure, and those of carcass characteristics with the GLM procedure of SAS, using weight at slaughter as covariable. MLP was higher (P0.05 by effect of ram breed. It is concluded that Bb ewes are more prolific than Dor ewes; male lambs of Dam rams had post-weaning growth response and carcass yield similar to those of Dor rams, although the female lambs of Dor rams were heavier than those of Dam rams.

1985-01-01

Histological changes in primary follicles of ewes after a five-day protracted exposure to gamma rays were studied by qualitative and micrometric methods. The experiment was carried out in the anoestrous period with 21 ewes of the Slovak Merino breed, divided into three groups. The first control group (five ewes) was not irradiated. The second and third groups (each included eight ewes) were irradiated with 60 Co gamma rays for a period of five days to the total dose of 4.8 Gy. All ewes including the control ones were given Ampicillin Spofa 250 mg per head/day during the period of ten days after irradiation. The third group was administered apart from this a mixture of vitamins, Roboran H, at the dose of 10 g per head/day. The animals were slaughtered on the fifth day of irradiation and on the tenth day after the end of irradiation. The ovaries processed by a routine histological method were cut in 7 μm slices in a series of 70 μm and stained with hematoxylin-eosine. By qualitative histomorphological analysis of the oocytes of primary follicles, chromatin aggregation, pycnosis of nuclei, pronounced acidophilia of oocyte cytoplasm, their shrinking and disintegration were determined. In intact primary follicles, mitotic division of follicular cells stopped and the proportion of follicular cells with pycnotic nuclei increased after irradiation. The results show that the five-day protracted exposure to gamma rays to the total dose of 4.8 Gy caused pronounced degenerative changes in the anoestrous period. Administration of antibiotics or vitamins had no significant effect on the stated histomorphological changes. (author)

This study evaluated the influence of artificial insemination (AI) by cervical retraction (CRI) on serum levels of interferon gamma (IFNγ) and interleukin-10 (IL-10) in ewes. Synchronized pluriparous Santa Inês ewes were subjected to natural mating (NM, n = 8) and AI, which was performed for a fixed time (55 ± 1 hour) by CRI (n = 8) or laparoscopy (n = 8). Ewes were classified as pregnant, with return to estrus (RE) or with embryonic loss (EL). Blood samples were collected on Day 0, Day 3, Day 5, Day 12, and Day 17 (Day 0 = AI/NM) for progesterone dosage and cytokines were quantified from Day 0 to Day 12. Progesterone levels were constant, except for a decrease in ewes with RE at Day 17 (P ewes with EL had lower serum levels of IFNγ and IL-10 than pregnant ewes and ewes with RE, regardless of the reproductive method used, with averages of 769.1, 714.9, and 555.7 pg/mL for IFNγ and 713.8, 699.3, and 578.7 pg/mL for IL-10 in pregnant ewes, ewes with RE and EL, respectively (P ewes does not alter the profile of serum cytokines IFNγ and IL-10 and does not induce an inflammatory reaction that can compromise pregnancy.

Crude glycerin is a gluconeogenic substrate in ruminants and may help to decrease the occurrence of pregnancy toxemia. The objective in this trial was to determine the effects of feeding a diet containing crude glycerin on DMI, milk yield, milk composition, and blood metabolites in periparturient ewes and lamb performance. One hundred eighteen 90 (±1.1)-d pregnant Santa Inês ewes were used. After lambing, 32 ewes (62.8 ± 1.3 kg BW) were allotted in a randomized complete block design defined by prelambing diet, BW, BCS, lambing date, type of birth (single or twin), and sex of offspring. Diets were isonitrogenous (13.0 ± 0.3% CP, DM basis), composed of concentrate and raw sugarcane bagasse (70:30 ratio, DM basis), and fed ad libitum daily. Crude glycerin (83.6% glycerol) levels were 0 or 10% (DM basis), corresponding to the experimental diets G0 and G10, respectively. From 8 until 56 d of lactation, DMI was determined. In the same period, once a week at 1000 h, the ewes were separated from the lambs and mechanically milked after intravenous administration of 10 IU of synthetic oxytocin. Three hours after the first milking, ewes were milked again and milk yield and composition were determined. Glucose, NEFA, and β-hydroxybutyrate (BHBA) were determined at -14, -7, 0, 7, 14, 28, and 56 d relative to lambing and insulin was determined at -14, -7, 0, and 7 d. Crude glycerin did not affect DMI (2.2 kg/d for G0 vs. 2.2 kg/d for G10; = 0.93) or milk production (171 g/3 h for G0 vs. 164 g/3 h for G10; = 0.66). However, there was a decrease ( = 0.01) in milk fat percentage (8.1% for G0 vs. 7.0% for G10) for ewes fed glycerin. Ewes fed the G10 diet had decreased ( ewes fed the G10 diet (0.46 mmol/L for G0 vs. 0.61 mmol/L for G10). There was no effect of diets fed to ewes on lamb growth from birth to weaning. Crude glycerin improved energy balance of periparturient ewes, suggesting a reduced risk of developing clinical metabolic-related disorders. Crude glycerin can be

Full Text Available Abstract Background Hypoxia regulates gene expression via the transcription factor HIF (Hypoxia-Inducible Factor. Little is known regarding HIF expression and function in primary bone sarcomas. We describe HIF expression and phenotypic effects of hypoxia, hypoglycaemia and HIF in Ewing's sarcoma and osteosarcoma. Methods HIF-1α and HIF-2α immunohistochemistry was performed on a Ewing's tumour tissue array. Ewing's sarcoma and osteosarcoma cell lines were assessed for HIF pathway induction by Western blot, luciferase assay and ELISA. Effects of hypoxia, hypoglycaemia and isoform-specific HIF siRNA were assessed on proliferation, apoptosis and migration. Results 17/56 Ewing's tumours were HIF-1α-positive, 15 HIF-2α-positive and 10 positive for HIF-1α and HIF-2α. Expression of HIF-1α and cleaved caspase 3 localised to necrotic areas. Hypoxia induced HIF-1α and HIF-2α in Ewing's and osteosarcoma cell lines while hypoglycaemia specifically induced HIF-2α in Ewing's. Downstream transcription was HIF-1α-dependent in Ewing's sarcoma, but regulated by both isoforms in osteosarcoma. In both cell types hypoglycaemia reduced cellular proliferation by ≥ 45%, hypoxia increased apoptosis and HIF siRNA modulated hypoxic proliferation and migration. Conclusions Co-localisation of HIF-1α and necrosis in Ewing's sarcoma suggests a role for hypoxia and/or hypoglycaemia in in vivo induction of HIF. In vitro data implicates hypoxia as the primary HIF stimulus in both Ewing's and osteosarcoma, driving effects on proliferation and apoptosis. These results provide a foundation from which to advance understanding of HIF function in the pathobiology of primary bone sarcomas.

The importance of PET/CT in the evaluation of patients with Ewing tumors

Directory of Open Access Journals (Sweden)

Júlio Brandão Guimarães

2015-06-01

Full Text Available Abstract The effective evaluation for the treatment of patients with Ewing tumors depends on the accuracy in the determination of the primary tumor extent and the presence of metastatic disease. Currently, no universally accepted staging system is available to assess Ewing tumors. The present study aimed at discussing the use of PET/CT as a tool for staging, restaging and assessment of therapeutic response in patients with Ewing tumors. In spite of some limitations of PET/CT as compared with anatomical imaging methods, its relevance in the assessment of these patients is related to the capacity of the method to provide further physiological information, which often generates important clinical implications. Currently, the assessment of patients with Ewing tumor should comprise a study with PET/CT combined with other anatomical imaging modalities, such as radiography, computed tomography and magnetic resonance imaging.

Differential effects of mineralocorticoid blockade on the hypothalamo-pituitary-adrenal axis in pregnant and nonpregnant ewes

Lingis, Melissa; Richards, Elaine M.

2011-01-01

During pregnancy, plasma ACTH and cortisol are chronically increased; this appears to occur through a reset of hypothalamo-pituitary-adrenal (HPA) activity. We have hypothesized that differences in mineralocorticoid receptor activity in pregnancy may alter feedback inhibition of the HPA axis. We tested the effect of MR antagonism in pregnant and nonpregnant ewes infused for 4 h with saline or the MR antagonist canrenoate. Pregnancy significantly increased plasma ACTH, cortisol, angiotensin II, and aldosterone. Infusion of canrenoate increased plasma ACTH, cortisol, and aldosterone in both pregnant and nonpregnant ewes; however, the temporal pattern of these responses differed between these two reproductive states. In nonpregnant ewes, plasma ACTH and cortisol transiently increased at 1 h of infusion, whereas in pregnant ewes the levels gradually increased and were significantly elevated from 2 to 4 h of infusion. MR blockade increased plasma aldosterone from 2 to 4 h in the pregnant ewes but only at 4 h in the nonpregnant ewes. In both pregnant and nonpregnant ewes, the increase in plasma aldosterone was significantly related to the timing and magnitude of the increase in plasma potassium. The results indicate a differential effect of MR activity in pregnant and nonpregnant ewes and suggest that the slow changes in ACTH, cortisol, and aldosterone are likely to be related to blockade of MR effects in the kidney rather than to effects of MR blockade in hippocampus or hypothalamus.

Systemic violence against Syrian refugee women and the myth of effective intrapersonal interventions.

Science.gov (United States)

Yasmine, Rola; Moughalian, Catherine

2016-05-01

Since the uprising in Syria in March 2011, over 4.3 million Syrians have fled to neighboring countries. Over a million have sought refuge in Lebanon, constituting almost a quarter of the Lebanese population and becoming the largest refugee population per capita in the world. With inequitable health coverage being a longstanding problem in Lebanon, Syrian refugee women's health, and specifically their sexual and reproductive health, is disproportionately affected. An increase in gender-based violence and early marriage, a lack of access to emergency obstetric care, limited access to contraception, forced cesarean sections, and high cost of healthcare services, all contribute to poor sexual and reproductive health. In this commentary, we conceptualize violence against Syrian refugee women using the ecological model, exploring the intersections of discrimination based on ethnicity, gender, and socioeconomic status, while critiquing interventions that focus solely on the intrapersonal level and ignore the role of microsystemic, exosystemic, and macrosystemic factors of negative influence. These social determinants of health supersede the individual realm of health behavior, and hinder women in taking decisions about their sexual and reproductive health. Copyright © 2016 Elsevier Inc.

Sex division of labour in Syrian school textbooks

Science.gov (United States)

Alrabaa, Sami

1985-12-01

The sexist division of labour, particularly in the occupational sector, which is believed to be more eminent in developing countries than in the developed ones, is reinforced by school textbooks. This state of affairs is hampering sex-role equality on the way to emancipation. Various Syrian school textbooks have been scrutinized and proved to be malebiased in content and language. Despite quantitative growth of education, the emancipatory quality of the school textbooks leaves much to be desired. The government has had the chance since 1963 to produce textbooks conductive to its promise of sex-role equality in education. The textbooks portray males for a bustling world of decision making, while conditioning the females to seek fulfilment in the background where servitude and support are the only requirement. Females are derogated and victimized. These contents, which are internalized at school and reproduced in society, certainly do not serve development. The exclusion of one-half of the population from contributing to the tasks of development is a waste of human talent which no society can afford. Furthermore, the sexist portrayal of females in Syrian textbooks is a pale reflection of Arab women in Arab history and literature.

Radiation-induced anorexia in Syrian hamsters

Energy Technology Data Exchange (ETDEWEB)

Kindt, A.; Sattler, E.L.; Schraub, A.

1980-10-01

The recovery of Syrian hamsters after split dose application (interval 11 days) was studied on the basis of the weight response and of food uptake. Two periods of weight loss and anorexia can be distinguished, an early one immediately after irradiation and a secondary one 6-10 days later. The secondary response is a function of the radiation dose and allows to distinguish survivors from non-survivors, since it is much more pronounced and longerlasting in the latter than in the former. The first response appears not to be influenced by a previous conditioning irradiation.

2015-10-01

This study aimed to investigate if intravenous maternal Arg administration to well-fed twin-bearing ewes, from 100 to 140 d of gestation or birth, could enhance placental development and placental nutrient transport. Ewes received intravenous infusions of saline (control) or 345 μmol Arg HCl/kg of BW 3 times daily from d 100 of pregnancy (P100) to d 140 of pregnancy (P140; cohort 1) or from P100 to birth (cohort 2). At P140, ewes in cohort 1 were euthanized and individual placentae per fetus were dissected and placentomes were classed per type (A to D) and size (light to heavy). Placentome number and individual weight were recorded. As an indicator of placental nutrient transport, blood plasma was collected from the uterine ovarian vein (UOV), uterine artery (UA), and umbilical vein and artery at the time of euthanasia and analyzed for metabolites and free AA concentrations. The ewes in cohort 2 were allowed to lamb and lambs were weighed at birth. The expelled placenta was dissected and number of cotyledons and weights of total cotyledons, remaining fetal membranes, and total placenta were recorded. At P140, Arg-infused ewes had a 63% ( = 0.03) greater number of unoccupied caruncles than control ewes. No differences were observed for placental weight at P140. At birth, lambs from Arg-infused ewes tended to have 11% ( = 0.09) greater placental weight and 34% ( = 0.03) greater total cotyledon weight compared with control lambs. Arginine-infused ewes (Arg-infused) had increased concentrations of Arg ( = 0.0001) and ornithine (Orn; = 0.004) but decreased concentrations of Met ( = 0.01) and His ( = 0.02 and = 0.09, respectively) compared with control ewes in plasma UOV and UA. Fetuses from Arg-infused ewes had increased concentrations of Orn ( = 0.005) and decreased concentrations of His ( = 0.006), Met ( = 0.003), and Lys ( = 0.01) but no differences in Arg ( > 0.10) concentrations were found compared with control fetuses in umbilical artery and vein plasma.

The Ewing's sarcoma family is a group of small round cell tumors which accounts for 10-15% of all primary bone neoplasms. The aim of this study was to evaluate the survival of Ewing's sarcoma patients in our province and to determine of influencing factors. All patients with documented Ewing's sarcoma/ primitive neuroectodermal tumor(PNET) family pathology were enrolled in this study during a period of eight years. For all of them local and systemic therapy were carried out. Overall and event free survival and prognostic factors were evaluated. Thirty two patients were enrolled in the study. The median age was 17.5 years. Twenty (65.2%) were male and 9 (28.1%) were aged 14 years or less. Mean disease free survival was 26.8 (95%CI; 13.8-39.9) months and five year disease free survival was 26%. Mean overall survival was 38.7 months (95%CI; 25.9-50.6) and median overall survival was 24 months. Five year overall survival was 25%. From the variables evaluated , only presence of metastatic disease at presentation (p value=0. 028) and complete response (p value =0. 006) had significant relations to overall survival. Survival of Ewing's sarcoma in our province is disappointing. It seems to be mostly due to less effective treatment. Administration of adequate chemotherapy dosage, resection of tumor with negative margins and precise assessment of irradiation volume may prove helpful.

Evaluation of therapeutic results in Ewing's sarcoma

Johnson, R.E.; Pomeroy, T.C.

1975-01-01

The philosophy pervading the treatment approach to Ewing's sarcoma was to have therapy encompass all foci of disease, including sites of occult or potential involvement in addition to obvious clinical manifestations. The experience with integrated methods of treatment in 66 consecutive patients at the National Cancer Institute is reviewed. A median survival of 18 months (44 percent 2 year survival rate) for patients with recognizable metastases on admission bears impressive witness to the value of adjuvant therapy in Ewing's sarcoma. Even more encouraging, an uncorrected 5 year survival rate of 53 percent (42 percent continuously free of disease) for patients given ''pyrophylactic'', adjuvant therapy indicates the potential for permanent control of disease in a significant fraction of cases with clinically localized primary tumors.

Ewing's sarcoma is a primary malignancy of the bone affecting individuals in the second decade of life. Primary sarcomas of the spine are rare and the occurrence of Primary Ewing's sarcoma in the spine is very rare. Ewing's sarcoma occurring in the spine is divided into two types, Ewing's sarcoma of sacral spine which are very aggressive with poor prognosis and Ewing's sarcoma of the non sacral spine which is an extremely rare occurrence. Patient may present with neurological deficit when the tumour extends into the spinal canal causing spinal cord compression. Magnetic resonance imaging (MRI) is very sensitive in diagnosing the tumour and defining the extent of the tumour. Here we report an 18-year-old boy who presented with back pain and complete paraplegia of two months duration. The MRI gave a differential diagnosis of infective pathology due to the fluid collection in the paraspinal region, followed by primary malignancy as the second diagnosis. Patient underwent posterior spinal decompression and stabilization, and intaoperatively there was significant collection of pus whose culture showed no growth. The histopathology and immunohistochemistry studies confirmed the diagnosis of Ewing's sarcoma and patient was started on combination chemotherapy and radiotherapy.

Prions in milk from ewes incubating natural scrapie.

Directory of Open Access Journals (Sweden)

2008-12-01

Full Text Available Since prion infectivity had never been reported in milk, dairy products originating from transmissible spongiform encephalopathy (TSE-affected ruminant flocks currently enter unrestricted into the animal and human food chain. However, a recently published study brought the first evidence of the presence of prions in mammary secretions from scrapie-affected ewes. Here we report the detection of consistent levels of infectivity in colostrum and milk from sheep incubating natural scrapie, several months prior to clinical onset. Additionally, abnormal PrP was detected, by immunohistochemistry and PET blot, in lacteal ducts and mammary acini. This PrP(Sc accumulation was detected only in ewes harbouring mammary ectopic lymphoid follicles that developed consequent to Maedi lentivirus infection. However, bioassay revealed that prion infectivity was present in milk and colostrum, not only from ewes with such lympho-proliferative chronic mastitis, but also from those displaying lesion-free mammary glands. In milk and colostrum, infectivity could be recovered in the cellular, cream, and casein-whey fractions. In our samples, using a Tg 338 mouse model, the highest per ml infectious titre measured was found to be equivalent to that contained in 6 microg of a posterior brain stem from a terminally scrapie-affected ewe. These findings indicate that both colostrum and milk from small ruminants incubating TSE could contribute to the animal TSE transmission process, either directly or through the presence of milk-derived material in animal feedstuffs. It also raises some concern with regard to the risk to humans of TSE exposure associated with milk products from ovine and other TSE-susceptible dairy species.

The authoritarian castling of the Syrian regime: from popular uprising to civil war

Full Text Available Instead of hastening political change, the Syrian uprising has led to greater authoritarianism. At first, president Bashar al-Assad adopted various cosmetic reforms (a party law and constitutional referendum, which were designed more as a survival strategy than a genuine process of political liberalisation. In its first four years, the Syrian crisis has gone from being an anti-authoritarian popular uprising to a proxy war with the active presence of Saudi Arabia, Iran, Qatar and Turkey. Control of the state apparatus on the part of the Alawite minority has been instrumentalised by the Salafist and jihadist groups to intensify sectarianism and claim the establishment of an Islamic State.

In war areas a lot of children die as well as adults. According to UNICEF, almost 2 million children have died in the wars took place in the last 10 years. In this study, we aimed to evaluate demographical data and injury characteristics of Syrian children who were wounded in Syria Civil War and died while being treated in Turkey. Postmortem examination and autopsy reports of 985 forensic deaths from Hatay -a Syrian neighborhood city of Turkey-between January 2012 and August 2014 were analyzed retrospectively. Among 763 Syrian people who were wounded in the war and died while being treated in Turkey, 140 cases (18.3%) who were younger than 18 years of age were taken into the scope of this study. Among those cases 77.9% (n = 109) were male and 22.1% were female. Median ages of female cases are 14 (min-max: 2-18) and median age of female cases are 9 (min-max: 1-18). Frequency distribution is highest between 13 and 18 years of age (n: 71, 50.7%). In 70% (n: 98) of cases, cause of death is bombing and shrapnel injuries, 13.6% (19) of them were killed by gunshot wounds. According to injury sites most of the injuries were reported to be on multiple body parts (54.3%, n: 76) and only head and neck injuries (%30). Cause of death was intracranial bleeding and cerebral parenchymal injury in most of the cases (n: 66, %47.1) followed by vascular damage with external bleeding (n: 15, %10.7) and internal organ damage with internal bleeding (n: 15, %10.7). The cases had very high level Abbreviated Injury Scales and Injury Severity Sores. In conclusion, a lot of children have died in the Civil War of Syria. Their average abbreviated injury scale and injury severity score values reported very high. Children that we evaluated were mostly died of head and neck injuries predominantly caused by bombing attacks and Autopsies of them revealed fatal intracranial hemorrhages and parenchymal injuries.

To detect early changes in the metabolic profile of pregnant ewes subject to acute feed restriction at 130 days of gestation, and to establish indicators of risk for ovine pregnancy toxaemia (OPT) for diagnostic purposes. Twenty Corriedale ewes with known mating dates, carrying a single fetus, were used. Ewes were maintained on meadow grasslands and at 130 days of gestation were randomly divided in two groups of 10 ewes. The control group had ad libitum access to pasture. Ewes in the restricted group were subjected to an acute feed restriction for a maximum of 144 hours (6 days), with free access to water. From the start (0 hours) until the end of feed restriction, blood samples were collected from all ewes to monitor concentrations of cortisol, non-esterified fatty acids (NEFA), ß-hydroxybutyrate (BOHB) daily, and glucose in plasma every 6 hours; urinary pH was also measured. Every 6 hours the food restricted ewes were observed to detect clinical signs of OPT e.g. apathy, grinding teeth, empty chewing movements, head leaning against the wall, tachypnea and not drinking water. In food-restricted ewes, concentrations of glucose decreased and differed from control ewes from 54 to 90 hours (pewes after 48 to 144 hours (pewes showed clinical signs of OPT after 102-132 hours. Mean concentrations of glucose, BOHB and cortisol differed between control and restricted ewes prior to the onset of clinical signs of OPT, after 48-96 hours of feed restriction (p<0.01). Mean gestational length, and time from birth to placental expulsion was not affected by the feed restriction. Our results suggest that concentrations of glucose, BOHB and cortisol in plasma may provide a precocious diagnosis of subclinical OPT, using values of 1.59 (SD 0.24) mmol/L, 2.26 (SD 1.03) mmol/L and 15.09 (SD 7.75) nmol/L, respectively. The identification of a potentially harmful metabolic imbalance could lead to the improvement of treatment success.

An Unusual Cause of Urinary Incontinence: Ewing's Sarcoma

Full Text Available Urinary incontinence in children can be originated mostly from urinary tract infections, but constipation, neurologic disorders, obstruction and tumors can also be considered among other causes. Pelvic tumors may present with back pain, bladder or bowel dysfunction. Ewing's sarcoma is among the small round-cell tumors of the childhood and potentially can arise from any part of the body. Here, we report an 11-year-old male presented with urinary incontinence and diagnosed as Ewing's sarcoma after 6 weeks' delay. Clinicians should suspect from pelvic tumors in the presence of urinary incontinence especially associated with low back pain. [Cukurova Med J 2015; 40(Suppl 1: 94-96

This study evaluated four models based on the number of eggs per gram of faeces (EPG) to segregate Pelibuey or Katahdin ewes during the lactation period into resistant or susceptible to gastrointestinal nematodes (GIN) in tropical Mexico. Nine hundred and thirty EPG counts of Pelibuey ewes and 710 of Katahdin ewes were obtained during 10 weeks of lactation. Ewes were segregated into resistant, intermediate and susceptible, using their individual EPG every week. Then, data of every ewe was used to provide a reference classification, which included all the EPG values of each animal. Then, four models were evaluated against such reference. Model 1 was based on the 10-week mean EPG count ± 2 SE. Models 2, 3 and 4 were based on the mean EPG count of 10, 5 and 2 weeks of lactation. The cutoff points for the segregation of ewe in those three models were the quartiles ≤Q1 (low elimination) and ≥Q3 (high elimination). In all the models evaluated, the ewes classified as resistant had lower EPG than intermediates and susceptible (P ewes classified as susceptible had higher EPG than intermediate and resistant (P 70 %). Model 3 tended to show higher sensitivity and specificity with the reference data, but no difference was found with other models. The present study showed that the phenotypic marker EPG might serve to identify and segregate populations of adult ewes during the lactation period. All models used served to segregate Pelibuey and Katahdin ewes into resistant, intermediate and susceptible. The model 3 (mean of 5 weeks) could be used because it required less sampling effort without losing sensitivity or specificity in the segregation of animals. However, model 2 (mean of 2 weeks) was less labour-intensive.

2011-08-01

Ewing's sarcoma is a rare, malignant tumour predominantly affecting young adolescent males. We describe a unique case of an isolated extra-skeletal metastasis from a skeletal Ewing's sarcoma primary, arising in the right sinonasal cavity of a young man who presented with severe epistaxis and periorbital cellulitis. Histologically, the lesion comprised closely packed, slightly diffuse, atypical cells with round, hyperchromatic nuclei, scant cytoplasm and occasional mitotic figures, arranged in a sheet-like pattern. Immunohistochemical analysis showed positive staining only for cluster of differentiation 99 glycoprotein. Fluorescent in situ hybridisation identified the Ewing's sarcoma gene, confirming the diagnosis. Complete surgical resection was achieved via a minimally invasive endoscopic transnasal approach; post-operative radiotherapy. Ten months post-operatively, there were no endoscopic or radiological signs of disease. Metastatic Ewing's sarcoma within the head and neck is incredibly rare and can pose significant diagnostic and therapeutic challenges. An awareness of different clinical presentations and distinct histopathological features is important to enable early diagnosis. This case illustrates one potential management strategy, and reinforces the evolving role of endoscopic transnasal approaches in managing sinonasal cavity and anterior skull base tumours.

1988-01-01

Elimination of [14C]heptachlor from body burdens of sheep was measured using mature ewes nursing single offspring, and the influence of exogenous ovine growth hormone (oGH) on elimination was studied. Six ewes (62 +/- 2.5 kg BW) were dosed (i.p.) once with [14C]heptachlor (2.04 mg/kg Bw; .88 microCi/mg heptachlor) and three were treated additionally with oGH (oGH; 5 mg/d) for 21 d. Three additional ewes served as controls. Excreta were collected each day for 21 d. Milk and blood were collected every 3rd d until ewes were euthanized at d 21. 14C activity was measured in excreta, milk, blood and tissues. Total cumulative activity of [14C]heptachlor and(or) metabolites in excreta (21 d) did not differ (P greater than .20) in ewes given oGH (25 +/- 2%) vs none (23 +/- 2%). Milk yield and protein content were unaffected (P greater than .10) by oGH. Ewes given oGH eliminated 2.2 +/- 2% of total 14C dosage into milk during 21 d, whereas ewes untreated with oGH eliminated 1.3 +/- .2% (P less than .10); total 14C activity eliminated into milk plus excreta was similar for ewes given oGH or none (P greater than .10). For all six ewes, half-times (T1/2) for distribution and elimination of 14C activity (heptachlor and metabolites) were 1.5 d and 11.7 d, respectively. Blood concentrations of 14C activity during 21 d yielded elimination half-time as 23 d. Unlike bovines, which eliminate heptachlor slowly (T1/2 approximately 70 to 80 d) and mainly into milk fat, lactating ovines eliminated heptachlor and(or) metabolites mainly into excreta and about sixfold faster than bovines

Purpose: In the Cooperative Ewing's Sarcoma Study 86 and the European Intergroup Cooperative Ewing's Sarcoma Study 92, hemithorax irradiation (RT) was performed in patients with Ewing tumors of the chest wall involving the pleura or contaminating the pleural cavity. In a retrospective analysis, the outcomes of these patients were evaluated and compared with those of patients with chest wall tumors who did not receive hemithorax RT. Methods and Materials: Between 1985 and 1996, 138 patients presented with nonmetastatic Ewing tumors of the chest wall. They were treated in a multimodal treatment regimen that included polychemotherapy and local therapy depending on the tumor characteristics. Hemithorax RT was performed at a dose of 15 Gy for patients <14 years old and 20 Gy for patients ≥14 years old. Forty-two patients received hemithorax RT (Group 1) and 86 patients did not (Group 2). The data were insufficient for the other 10 patients. Results: Comparing both groups, the initial pleural effusion, pleural infiltration, and intraoperative contamination of the pleural space were significantly more frequent in Group 1. The event-free survival rate after 7 years was 63% for patients in Group 1 and 46% for patients in Group 2 (not statistically significant). The 7-year local relapse rate (including combined local-systemic relapses) was 12% in Group 1 and 10% in Group 2; the corresponding systemic relapse rates were 22% and 39%. Conclusion: Patients with chest wall tumors who received hemithorax RT were negatively selected; yet the rate of event-free survival was better for patients who received hemithorax RT than for those who did not (although the difference was not statistically significant). This result was due to a reduction of metastases, mainly lung metastases. Local control was equivalent between the two groups. These favorable results have caused us to continue using hemithorax RT to treat high-risk patients with Ewing tumors of the chest wall

To determine if there was a benefit from treating ewes with a low body condition score (BCS) with long acting anthelmintic products pre-lambing and to compare the effects of two commonly used treatment options. The study was conducted on a single commercial hill country sheep and beef property in the central North Island of New Zealand. Mixed age twin-bearing ewes were preselected by the farmer as being in poor condition 4 weeks before the planned start of lambing, and were sequentially drafted into three equal groups identified with coloured ear tags. The negative control group (n=199) received no anthelmintic treatment; the other two groups received either a controlled release capsule (CRC) containing abamectin, albendazole, Se and Co (n=200) or a long-acting injection of moxidectin (n=200). All ewes were body condition scored (1-5 scale) and weighed at pre-lambing, docking (65 days after treatment) and at weaning (127 days after treatment). Faecal nematode egg counts (FEC) were carried out on 10 ewes from each group at these three times. Most lambs were matched to the ewe treatment groups at weaning, and weighed. At weaning the mean body weight of ewes treated with moxidectin was 3.2 (95% CI=2.3-4.3) kg heavier than controls, and of ewes treated with CRC was 3.6 (95% CI=2.5-4.5) kg heavier than control ewes (pewes had a BCS≥3. At weaning, more ewes treated with CRC (140/194; 72%) or moxidectin (122/187; 65%) had a BCS≥3 than control ewes (55/179 (31%); pewes from the treatment groups, the mean weight at weaning of lambs from ewes treated with moxidectin was 2.6 (95% CI=1.9-3.3) kg heavier, and from ewes treated with CRC was 2.6 (95% CI=1.9-3.4) kg heavier than lambs from control ewes (pewes with low BCS pre-lambing with long acting anthelmintic treatments (moxidectin long acting injection or CRC) resulted in an increase in mean body weight of the ewes and lambs at weaning. There were no significant differences between the two pre-lambing treatments used

Establishing capabilities for combating illicit trafficking: the Syrian experience

Since the late 80's, Syria has been taking steps towards combating illicit trafficking or inadvertent movement involving radioactive or nuclear material within the country or across its border. By applying the proper combination of technical and procedural measures, an acceptable level of performance has been achieved. The measures undertaken by AECS include anticipative measures, which aim at identifying potential loss of control over radioactive sources and potential illicit trafficking within the country, as well as defensive measures which aim at detection of and response to events of illicit trafficking. In addition, a tight follow up of radiation source along their entire lifetime in the Syrian territory, supported by proper data analysis is one of the most efficient tools for identifying potential loss of control over sources. AECS has established Border Monitoring Centers (BMC) in almost all border crossings. They work in close cooperation with the customs and other relevant authorities at the Syrian borders. AECS has been also providing the necessary training for the frontline officers. (author)

The conflict in Syria that began in 2011 has resulted in the exodus of over 5 million Syrian refugees to neighbouring countries, with more than one million refugees currently registered by UNHCR in Lebanon. While some are living in tented settlements, the majority are living in strained conditions in rented accommodation or collective shelters in the Bekaa Valley next to Syria. Adolescents are particularly vulnerable in any crisis. In 2013-4, the American University in Beirut in collaboration with the Women's Refugee Commission, Johns Hopkins and Save the Children, sought to understand the specific experiences of very young adolescents, those 10-14 years of age, in this protracted crisis context. The study was conducted in 2014 in Barelias and Qabelias - two urban areas located close to each other in the Beka'a valley that has a large concentration of Syrian refugees. Focus group discussions (FGDs), including community mapping and photo elicitation, were conducted with 10-12 and 13-14 year old Syrian refugee adolescents, in order to obtain information about their experiences and perspectives. FGDs were also implemented with 15-16 year old Syrian refugees and separately also with adult refugees, to consider their perspectives on the needs and risks of these adolescents. A total of 16 FGD (8 for each sex, with 6-9 participants in each) were conducted in Arabic across the two sites, with 59 female participants and 59 male participants. The experiences and risks faced by these adolescents were significantly impacted by economic strain and loss of educational opportunities during displacement, and only a minority of adolescents in the study reported attending school. Additionally, on-going protection risks for girls were felt to be higher due to the crisis and displacement. In Lebanon this has resulted in increased risks of child marriage and limitations in mobility for adolescent girls. Adolescents, themselves expressed tensions with their Lebanese counterparts and

Bone Tumor Environment as a Potential Therapeutic Target in Ewing Sarcoma.

Science.gov (United States)

Redini, Françoise; Heymann, Dominique

2015-01-01

Ewing sarcoma is the second most common pediatric bone tumor, with three cases per million worldwide. In clinical terms, Ewing sarcoma is an aggressive, rapidly fatal malignancy that mainly develops not only in osseous sites (85%) but also in extra-skeletal soft tissue. It spreads naturally to the lungs, bones, and bone marrow with poor prognosis in the two latter cases. Bone lesions from primary or secondary (metastases) tumors are characterized by extensive bone remodeling, more often due to osteolysis. Osteoclast activation and subsequent bone resorption are responsible for the clinical features of bone tumors, including pain, vertebral collapse, and spinal cord compression. Based on the "vicious cycle" concept of tumor cells and bone resorbing cells, drugs, which target osteoclasts, may be promising agents as adjuvant setting for treating bone tumors, including Ewing sarcoma. There is also increasing evidence that cellular and molecular protagonists present in the bone microenvironment play a part in establishing a favorable "niche" for tumor initiation and progression. The purpose of this review is to discuss the potential therapeutic value of drugs targeting the bone tumor microenvironment in Ewing sarcoma. The first part of the review will focus on targeting the bone resorbing function of osteoclasts by means of bisphosphonates or drugs blocking the pro-resorbing cytokine receptor activator of NF-kappa B ligand. Second, the role of this peculiar hypoxic microenvironment will be discussed in the context of resistance to chemotherapy, escape from the immune system, or neo-angiogenesis. Therapeutic interventions based on these specificities could be then proposed in the context of Ewing sarcoma.

Study of Blood Metabolites Changes of Purebred Ghezel and Crossbred Arkhar Merinos × Ghezel Ewes during Late Pregnancy

2016-11-01

Full Text Available Introduction As pregnancy progresses, nutrient requirements of fetus and thereby ewe increases and some changes in the levels of blood metabolites including glucose, cholesterol and total protein may occur. During gestation, maternal tissues contribute to supplying energy that required for fetus resulting in changes of ewe blood metabolites; however other factors such as breed, age, feeding type of ewes during gestation and season may influence them. The study of blood metabolic changes in different phases of reproductive cycle can be helpful in detecting abnormal situations of ewes and preventing of metabolic disorders such as pregnancy toxemia and fatty liver syndrome. There is little information about the effect of different genotypes on blood metabolites and the occurrence of metabolic disorders in late pregnancy. Therefore the aim of the present study was to determine changes in blood metabolites of purebred Ghezel and ArkharMerino× Ghezel crossbred ewes during late pregnancy and effect of crossbreeding of Iranian purebred sheep with Merino sheep on metabolite level changes in these two groups of sheep and study of susceptibility to metabolic disease in late pregnancy. Materials and Methods In the present study, fifty five pregnant Ghezel ewes (36 singles and 15 twins and 34 pregnant crossbred ewes (20 singles and 14 twins were used. Estrus synchronization of all ewes was done using CIDR. CIDR were removed 14 days later and all ewes were injected PMSG intramuscularly and then mated with rams. All of the ewes were grazing in the pasture during pregnancy, but in the last two months of pregnancy, feeding of ewes was manually. Blood samples were collected by vacuum tubes during four hours after feeding from the jugular vein of ewes on 15 days prior to mating period and on days 90, 120 and 140 of the pregnancy. Blood samples were centrifuged with 4000 rpm for 12 minutes to extract blood serum and then sera were frozen in -20oC until further

The radiographic features of Ewing's sarcoma of the bones of the hands and feet are reviewed utilizing cases obtained from the Mayo Clinic patient files and the consultation files of Drs. D.C. Dahlin and K.K. Unni. This series consists of a total of 43 cases of pathologically proven Ewing's sarcoma involving the small bones of the hands and feet. The classic radiographic features of Ewing's sarcoma in the long bones, including lytic, permeative destruction, aggressive periosteal reaction, cortical violation, and a soft tissue mass, are also seen in the bones of the hands and feet, with similar frequency. These classic features are most commonly present in lesions affecting the short tubular bones. Lesions affecting the tarsal bones more often demonstrate atypical radiographic features. These atypical radiographic appearances may play a role in the reported delay in diagnosis of Ewing's sarcoma within the tarsal bones. (orig.)

The Syrian Vulnerable Person Resettlement Programme: evaluation of Edinburgh's reception arrangements.

Weir, Katherine E A; Wilson, Sheila J; Gorman, Dermot R

2017-11-07

During 2015 and 2016 a group of Syrian refugees were resettled in Edinburgh, Scotland under the United Kingdom Government Syrian Vulnerable Person Resettlement Programme. We evaluate the strengths and weaknesses of the settling in arrangements for these refugees. Semi-structured interviews were conducted with five Arabic interpreters who had worked extensively with these refugees. Interviews sought their impressions about what went well or was not successful. Interviews were transcribed and key themes extracted and analysed. Six themes emerged: 'first impressions', language skills, different healthcare systems, health of the refugees, relationships between the interpreters and refugees and support for the interpreters. The welcoming arrangements went well and exceeded refugees' and interpreters' expectations. There was perhaps too much information given immediately and reinforcing details about various public services and facilities after a first few months would be worthwhile. The Syrians were unfamiliar with NHS structures and found lack of direct specialist access surprising. Problems were amplified by low English levels. A need for Arabic literacy classes was also identified. Interpreters were often used informally out-of-hours and a better system with first contact in Arabic should be established. Interpreters find this work particularly stressful and the provision of psychological support for them should be prioritized. © The Author 2017.

The ongoing Syrian war has resulted in many changes in the social and economic life of Syrians. To date, no study has documented the relationship between smoking behaviour and the war. To determine the prevalence of cigarette smoking among university students during the crisis in Damascus, Syrian Arab Republic, and the impact of the war on smoking behaviour. We conducted an anonymous online cross-sectional survey of 1027 undergraduate students from all years and colleges at Damascus University. The overall prevalence of tobacco smoking was 24.73% for cigarettes and 30.4% for waterpipe. Prevalence of cigarette smoking was significantly higher in men, non-health profession students, and in students living away from their families. There was no significant difference in prevalence of smoking cigarettes when comparing students according to their origin (urban vs rural), year of study, and change of residence due to war. War was associated with a significant increase in mean number of cigarettes smoked daily, and 53.1% of smokers reported that the number of cigarettes consumed per day had increased since the beginning of the war. Increased smoking is an additional health concern in areas of conflict and may require special consideration and efforts by public health authorities.

Full Text Available Productivity of F1 crossbred ewes between the prolific D’man and the local Queue fine de l’Ouest breeds (D’man x QFO mated with terminal sires of the Brune noire de Suisse (BNS breed was evaluated and compared to that of (i QFO and D’man ewes respectively mated to rams of the same breed in a research station (ESAK and of (ii QFO ewes mated to rams of the same breed in a commercial farm (El-Mabrouka. In ESAK station, data collected between 1995 and 2003, and related to 343, 168 and 323 lambings of QFO, D’man, and F1 crosses D’man x QFO ewes, respectively, were used. At birth, the mean litter size was 1.17 ± 0.37, 1.76 ± 0.71, and 1.40 ± 0.54 for ewes of the QFO, D’man, and crosses D’man x QFO genotypes, respectively, whereas at 90 days after lambing, the corresponding figures were 1.13 ± 0.40, 1.65 ± 0.70, and 1.31 ± 0.54. The year of lambing, genotype of the ewe as well as their interaction were significant sources of variation of all litter sizes. At 10 days after lambing, the weight productivity of QFO ewes was 7.3 ± 2.5 kg, and was thus significantly higher (p < 0.05 than that of D’man (6.6 ± 2.7 kg, and D’man x QFO (7.0 ± 2.3 kg ewes. This trend was reversed 90 days after lambing with weight productivity of D’man x QFO, and D’man ewes reaching 22.9 ± 7.7 and 22.5 ± 12.0 kg, respectively, and that of QFO sheep 19.5 ± 6.7 kg. With the exception of the age of the ewe, all other sources of variation highly influenced (p < 0.001 most weight productivity traits. In El-Mabrouka farm, the data used concerned 1048 and 529 lambings of QFO, and D’man x QFO breeds, respectively, that occurred during years 1999, 2000 and 2001. The year of lambing, genotype of the ewe as well as its age were highly significant sources of variation for the litter size at birth. Crossbred ewes produced on average 0.2 lamb more than QFOs (p < 0.05. Difference in productivity at 70 days after lambing was approximately 3 kg in favor of D�

Experiments were carried out in Yankasa sheep to study the efficacy of progesterone for oestrous synchronization and the effect of various gonadotrophin treatments (pregnant mare serum gonadotrophin (PMSG), human chorionic gonadotrophin (HCG) and gonadotrophin releasing hormone (GnRH)) on ovulation rates and litter size, and to elucidate responses by monitoring progesterone concentration. Preliminary studies showed normal progesterone profiles during the cycle, and a mean ovulation rate and litter size of 1.36 ± 0.34 and 1.23 respectively. Following synchronization with progesterone pessaries, PMSG dosage influenced ovulation rates. When 500 IU PMSG was given to ewes, HCG injection had an additive effect of increasing ovulation rate. Plasma progesterone concentrations showed significant treatment effects, being increased in relation to an increase in ovulation rates. Ovulation in Yankasa ewes occurred between 30-32 hours from onset of oestrus. In a fertility trial, mean ovulation rates and corresponding litter size were 2.1 versus 1.8 and 1.5 versus 1.2 for PMSG treated and untreated ewes respectively. 24 refs, 8 figs, 5 tabs

Neutrality investigations of markers with forensic use are important to see if a phenotypic trait is being expressed in relation to the alleles of the marker. MiniSTR marker D22S1045 (locus 22q12.3) is localized near the breakpoint region of the EWS gene (22q12.2), which leads to the development of Ewing's Sarcoma. Analyzing allele frequencies and linkage disequilibrium in Ewing's sarcoma patients and non-affected populations, we found that the marker mD22S1045 was neutral when related to Ewing's Sarcoma.

To evaluate the effects of pre- and post-conception undernutrition (UN) on fetal and placental development at mid-gestation, 28 Katahdin × Pelibuey multiparous ewes were blocked by weight and assigned to the following four dietary treatments (n = 7 each): ewes fed 100% (control) or 60% of their nutritional requirements 30 days before mating (UNPre), 50 days after mating (UNPost) or during both periods (UNB). Four twin-bearing ewes were selected per treatment at day 50 post-conception and then slaughtered at day 75 of gestation to analyze their fetuses. Control fetuses were heavier (P ewes than UNB ewes, but not relative to ewes of other treatments. The number of placentomes per ewe and placental efficiency were unaffected by UN treatments. Compared to control, only UNB ewes exhibited variations (P ewes than placentas of control ewes (P ewes carrying twins is mainly altered when nutritional restriction occurs simultaneously before conception and during the first third of pregnancy.

Full Text Available The use of shearing during pregnancy has been described as a tool for improving productivity in sheep and for minimizing perinatal mortality in lambs through the increase of fetal development. This study assessed the effect of shearing around 74 days of gestation on the productive performance of ewes and lambs during the first month of life. Forty Corriedale ewes were inseminated in autumn in Southern Brazil. All ewes were kept together at the same pasture under extensive husbandry conditions. The ewes were randomly separated into two treatment groups: twenty animals were completely sheared at 74 ± 6 days of pregnancy, and twenty were kept without sheared during pregnancy, composing the control group. Ewes and their lambs were evaluated at three different times during the experiment: at birth, between 15 and 21 days post-partum and between 22 and 45 days post-partum. Ewes had their body condition score, body weight, placental weight, milk production and serum concentrations of beta-hydroxybutyrate measured, while lambs had hematocrit, hemoglobin, and plasma lactate and glucose, as well as body weight at birth and until wean determined. Values of hematocrit and hemoglobin were lower and body weight at birth and at wean was higher in the group of lambs born from sheared ewes. Placenta weight was higher in sheared ewes. Body condition score and beta-hydroxybutyrate showed no differences between groups. Milk production of sheared ewes (1.26 L/day was higher than in control group (0.93 L/day. Shearing ewes at 74 days of pregnancy was efficient for the better development of lambs at post-birth, reducing perinatal mortality rates.

Gene Expression Music Algorithm-Based Characterization of the Ewing Sarcoma Stem Cell Signature

Full Text Available Gene Expression Music Algorithm (GEMusicA is a method for the transformation of DNA microarray data into melodies that can be used for the characterization of differentially expressed genes. Using this method we compared gene expression profiles from endothelial cells (EC, hematopoietic stem cells, neuronal stem cells, embryonic stem cells (ESC, and mesenchymal stem cells (MSC and defined a set of genes that can discriminate between the different stem cell types. We analyzed the behavior of public microarray data sets from Ewing sarcoma (“Ewing family tumors,” EFT cell lines and biopsies in GEMusicA after prefiltering DNA microarray data for the probe sets from the stem cell signature. Our results demonstrate that individual Ewing sarcoma cell lines have a high similarity to ESC or EC. Ewing sarcoma cell lines with inhibited Ewing sarcoma breakpoint region 1-Friend leukemia virus integration 1 (EWSR1-FLI1 oncogene retained the similarity to ESC and EC. However, correlation coefficients between GEMusicA-processed expression data between EFT and ESC decreased whereas correlation coefficients between EFT and EC as well as between EFT and MSC increased after knockdown of EWSR1-FLI1. Our data support the concept of EFT being derived from cells with features of embryonic and endothelial cells.

A number of studies have investigated the role of serum lactate dehydrogenase (LDH) levels in patients with Ewing's sarcoma, although these have yielded inconsistent and inconclusive results. Therefore, the present study aimed to systematically review the published studies and conduct a meta-analysis to assess its prognostic value more precisely. Cohort studies assessing the prognostic role of LDH levels in patients with Ewing's sarcoma were included. A pooled hazard ratio (HR) with 95% confidence intervals (CIs) of overall survival (OS) or 5-year disease-free survival (DFS) was used to assess the prognostic role of the levels of serum LDH. Nine studies published between 1980 and 2014, with a total of 1,412 patients with Ewing's sarcoma, were included. Six studies, with a total of 644 patients, used OS as the primary endpoint and four studies, with 795 patients, used 5-year DFS. Overall, the pooled HR evaluating high LDH levels was 2.90 (95% CI: 2.09-4.04) for OS and 2.40 (95% CI: 1.93-2.98) for 5-year DFS. This meta-analysis demonstrates that high levels of serum LDH are associated with lower OS and 5-year DFS rates in patients with Ewing's sarcoma. Therefore, serum LDH levels are an effective biomarker of Ewing's sarcoma prognosis.

With over one million Syrian refugee children in the region, we undertook this study to characterize care-seeking behaviors and health service utilization for child refugees with the aim of informing humanitarian programming for non-camp settings in Jordan. A survey of Syrian refugees living outside of camps in Jordan was conducted using a 125 × 12 cluster design with probability proportional to size sampling to obtain a representative sample. The questionnaire focused on access to health services, including a module on care seeking for children. Care seeking was high with 90.9% of households with a child less than 18 years seeking medical care the last time it was needed. Households most often sought care for children in the public sector (54.6%), followed by private (36.5%) and charity sectors (8.9%). Among child care seekers, 88.6% were prescribed medication during the most recent visit, 90.6% of which obtained the medication. Overall, 49.4% of households reported out-of-pocket expenditures for either the consultation or prescribed medications at the most recent visit (mean $US21.1 and median $US0). Syrian refugees had good access to care for their sick children at the time of the survey; however, this has likely deteriorated since the survey because of the withdrawal of free access for refugees. The number of refugees in Jordan and relative accessibility of care has resulted in a large burden on the health system; the Jordanian government will require additional support if current levels of health access are to be maintained for Syrian refugees. © 2016 The Authors.

The aim of this study was to investigate the effect of Syrian refugees on the pharmaceutical sector in Jordan. Based on a standardized methodology developed by the WHO, Level II Facility (2009) structured questionnaires (including: medicine access [availability, affordability and geographical accessibility], quality, and rational use of medicines) were used to investigate the effect of Syrian refugees influx on the pharmaceutical sector in Jordan. Lists of essential medicines (N = 50) were included in the survey forms. The results showed more progress in all indicators for the public sector compared with the previous results in the 2009 survey and in comparison to the private sector. For example, access to medicines improved in the public sector while it decreased (if it did not remain the same) in the private sector. Also, average stock out duration time decreased dramatically in both public and private sectors. As indicated by the median price ratio (MPR), brand prices increased much in the public health facilities while they decreased by 23%-30% in the private sector. In northern areas where most Syrian refugees stay, a significant decrease in availability was noticed, in addition to the dramatic decrease in days of average stock out and adequate inventory record percentage of those medicines. In conclusion, despite the international help received to support health care provision and medications procurement for the refugees, more support is needed immediately.

In sheep, embryonic and fetal death during pregnancy can account for 25% to 50% of the total number of corpora lutea (and thus potential embryos). The objective of this study was to determine the effects of injectable and oral Arg supplementation provided for 14 d postbreeding on the reproductive performance of naturally stimulated fall lambing ewes. Rambouillet ewes ( = 210) were exposed to rams equipped with marking harnesses to induce cyclicity in April 2012. Upon estrus detection (d 0) ewes were randomly assigned, in a completely random design, to 1 of 6 treatments for a 14-d treatment period: injectable saline (CON; = 25), injectable Ala (IVALA; = 20), injectable Arg (IVARG; = 23), oral rumen-protected Arg (RPARG; = 20), oral fish meal (FM; = 24), or oral soybean meal (SBM; = 23). Daily treatments, except CON, IVALA, and SBM, were formulated to provide supplemental Arg at 30 mg·kg BW·d and were provided at 0800 h daily. Ewes receiving injectable treatments were provided 454 g corn/d postinjection, whereas ewes receiving oral supplements were provided a ground ration of their respective treatments with corn individually at 0800 h daily. Plasma and serum samples were collected on d 0, 2, 4, 6, 8, 10, 12, and 14 from 12 ewes per treatment to evaluate plasma progesterone and serum AA concentrations. At lambing, birth weight, birth type, and sex were recorded. Weaning weights were recorded when the average age of lambs was 85 d. No differences ( ≥ 0.39) were detected for pregnancy, prolificacy, and lambing rates or lamb birth weights among treatments. However, litter weaning weight tended to be greater ( = 0.06) and weaning rates were greater ( = 0.05) in Arg-injected ewes (1.09, 0.95, 1.29, 0.72, 1.00, and 0.86, respectively). Plasma progesterone and serum Arg concentrations showed a treatment and day effect ( < 0.001), but no treatment × day interaction ( ≥ 0.99) was observed. In contrast to previous research, supplemental Arg during the first 14 d of

Genetic Characterization Of Syrian Erwinia Amylovora Strains By Amplified Fragment Length Polymorphism Technique

International Nuclear Information System (INIS)

Ammouneh, H.; Arabi, M.; Shoaib, A.

2011-01-01

Thirty Erwinia amylovora strains, collected from the main rosaceous crop-growing regions in Syria, were chosen as representatives of all major pathogenicity groups and were genetically studied by AFLP. Eight primer combinations were utilized and approximately 300 scorable bands in total were generated. Based on similarity coefficient, E. amylovora strains were placed into a main cluster containing two sub clusters, indicating very low genetic variations among the studied pathogen. The existence of two plasmids, pEA29 (present in nearly all E. amylovora isolates) and pEL60 (present mainly in Lebanese strains), was confirmed using multiplex PCR in all tested Syrian E. amylovora strains, indicating that Lebanese and Syrian isolates may share a common origin.(author)

Multiparous ewes received 100% (control, C, n=13) or 50% (nutrient restricted, NR, n=14) of NRC dietary requirements from d28-d78 of gestation. On d78, 5 C and 6 NR ewes were necropsied. The remaining 8 C and 8 NR ewes were fed to 100% of NRC from d78-d135 and necropsied. Maternal blood was collected at both necropsies and at weekly intervals for assay of glucose, insulin and leptin. Fetal blood was collected at d78 and d135 necropsies for assay of glucose and lipids. Cotyledonary (COT) tissue was evaluated for protein and mRNA expression [fatty acid transporter (FATP)1, FATP4, CD36, glucose transporter (GLUT)1 and GLUT3], mRNA expression only [placenta fatty acid binding protein (FABPpm) and lipoprotein lipase (LPL)], or expression of phosphorylated and total protein forms [AMP kinase (AMPK)α, acetyl-CoA carboxylase (ACC), extracellular signal-regulated kinase (Erk)1/2, mammalian target of rapamycin (mTOR) and protein kinase B (Akt)].

Micro-Environmental Stress Induces Src-Dependent Activation of Invadopodia and Cell Migration in Ewing Sarcoma

Directory of Open Access Journals (Sweden)

Kelly M. Bailey

2016-08-01

Full Text Available Metastatic Ewing sarcoma has a very poor prognosis and therefore new investigations into the biologic drivers of metastatic progression are key to finding new therapeutic approaches. The tumor microenvironment is highly dynamic, leading to exposure of different regions of a growing solid tumor to changes in oxygen and nutrient availability. Tumor cells must adapt to such stress in order to survive and propagate. In the current study, we investigate how Ewing sarcoma cells respond to the stress of growth factor deprivation and hypoxia. Our findings reveal that serum deprivation leads to a reversible change in Ewing cell cytoskeletal phenotypes. Using an array of migration and invasion techniques, including gelatin matrix degradation invadopodia assays, we show that exposure of Ewing sarcoma cells to serum deprivation and hypoxia triggers enhanced migration, invadopodia formation, matrix degradation and invasion. Further, these functional changes are accompanied by and dependent on activation of Src kinase. Activation of Src, and the associated invasive cell phenotype, were blocked by exposing hypoxia and serum-deprived cells to the Src inhibitor dasatinib. These results indicate that Ewing sarcoma cells demonstrate significant plasticity in response to rapidly changing micro-environmental stresses that can result from rapid tumor growth and from necrosis-causing therapies. In response to these stresses, Ewing cells transition to a more migratory and invasive state and our data show that Src is an important mediator of this stress response. Our data support exploration of clinically available Src inhibitors as adjuvant agents for metastasis prevention in Ewing sarcoma.

Using Longitudinal Assessment on Extensively Managed Ewes to Quantify Welfare Compromise and Risks

Barber, Stuart; Hemsworth, Paul; Doyle, Rebecca

2018-01-01

Simple Summary Sheep managed extensively can be exposed to several welfare challenges during the year, and the risk of some diseases can increase in warmer and wetter seasons. In this study, the welfare of Merino ewes was examined over a calendar year. The welfare of these animals, kept on a single farm with consistent management, varied substantially. Overall, the largest number of ewes experienced compromise and risk to welfare at weaning, indicating that this was the most vulnerable time. The main welfare issues identified were under and over feeding, ewe mortality, lameness, ecto-parasites (flystrike) and mastitis, all of which could be improved by modifying management practices, such as improved nutritional management and monitoring and better tail docking procedures. Future research must consider that significant variation in the on-farm welfare of ewes occurs during a calendar year, which needs to be accounted for when conducting on-farm assessments. Abstract This study examined variation in the welfare of extensively managed ewes and potential welfare risks. A total of 100 Merino ewes (aged 2–4 years) were individually identified and examined at three key stages: pregnancy, lactation and weaning. Eight animal-based welfare measures were used to assess welfare: flight distance, body condition score (BCS), fleece condition, skin lesions, tail length, dag score, lameness and mastitis. Data were analysed by ANOVA and McNemar’s statistics. Overall, the average BCS of the group was in agreement with industry recommendations. However, a number of animals were classified with inadequate condition (either too thin or too fat) across the three observation periods. The presence of heavy dags was greatest at mid-lactation (87%, P welfare issues identified were under and over feeding, ewe mortality, lameness, ecto-parasites (flystrike) and mastitis, all of which have the potential to be reduced with improved management practices.

Full Text Available There is no data on the prevalence of overweight and obesity in young Syrian boys. Therefore, the present study aimed to provide baseline and reference data on the prevalence of overweight and obesity among young Syrian boys using skin-fold thickness measurements and deuterium dilution (DD as a reference method. The sample of 2470 healthy Syrian 18- to 19-year-old boys were enrolled in this study. SFTs were measured at the biceps (B, triceps (T, subscapular (SI and suprailiac locations (SS were done and validated using the DD technique as a reference method. Receiver operating characteristics (ROC curve was drawn to determine appropriate cut-off points of the Σ2 limb SFT (T+B, Σ2 trunk SFT (SI+SS, Σ4 SFT (T+B+SI+SS and Log Σ4 SFT for defining overweight and obesity. The overall prevalence of overweight and obesity in young Syrian boys, based on biceps SFT, triceps SFT, subscapular SFT, suprailiac SFT, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT, logarithm Σ4 SFT, and DDT were 35.3%, 32%, 31.6%, 14.8%, 32.9%, 26.6%, 28.1%, 24.1%, 46.5%, respectively. Strongly positive correlation was found between SFT and total body fat in adolescents. For diagnosing overweight on the basis of Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT, we propose the following cut-off points: 17.25 mm, 23.50 mm, 39.25 mm and 1.60, respectively. To predict obesity, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT threshold were increased to 23.25 mm, 32.50 mm, 55.25 and 1.75, respectively. Basing on SFT clearly leads to underestimates of the prevalence of weight problems among young boys. SFT measurement screen missed 11.2 to 31.7% of overall overweight and obesity cases.

This study aimed to evaluate the effectiveness of hormonal treatments on ovarian activity and reproductive performance in Barki and Rahmani ewes during non-breeding season. Forty-eight multiparous ewes, 24 Barki and 24 Rahmani ewes were divided into two groups, 12 lactating and 12 dry ewes for each breed. Controlled internal drug release (CIDR) device was inserted in all ewes for 14 days in conjunction with intramuscular 500 IU equine chronic gonadotrophin (eCG) at day of CIDR removal. Data were analysed using PROC MIXED of SAS for repeated measures. Breed, physiological status and days were used as fixed effects and individual ewes as random effects. Barki ewes recorded higher (p ewes. Lactating ewes recorded higher (p ewes. Number and diameter of large follicles recorded the highest (p ewes recorded longer (p ewes. In conclusion, CIDR-eCG protocol was more potent in improving ovarian activity in Barki compared to Rahmani ewes, but this protocol seems to induce hormonal imbalance in Barki ewes that resulted in increasing conception failure compared to Rahmani ewes. © 2017 Blackwell Verlag GmbH.

Radiation-induced anorexia in Syrian hamsters

Kindt, A.; Sattler, E.L.; Schraub, A.

1980-01-01

The recovery of Syrian hamsters after split dose application (interval 11 days) was studied on the basis of the weight response and of food uptake. Two periods of weight loss and anorexia can be distinguished, an early one immediately after irradiation and a secondary one 6-10 days later. The secondary response is a function of the radiation dose and allows to distinguish survivors from non-survivors, since it is much more pronounced and longerlasting in the latter than in the former. The first response appears not to be influenced by a previous conditioning irradiation. (orig.) [de

The magnitude of ovulation rate (OR) after hormonal induction in sheep should be considered when prolific genotypes are used. We investigated for the first time the effect of the Vacaria allele and its combined effect with the Booroola prolificacy mutation on OR after hormonal treatment during breeding and anoestrous season. A hundred forty-nine Ile de France crossbred ewes, raised in natural pastures in South Brazil, were used to evaluate the OR after treatment with progestagen (MAP) followed or not by equine chorionic gonadotrophin (eCG) treatment (MAP + eCG). During the breeding season, 96% MAP-treated ewes ovulated in comparison to 97% of MAP + eCG-treated females. The double heterozygous carriers (BNVN) presented the higher OR, followed by the single Vacaria (NNVN) and Booroola (BNNN) heterozygous females and least the wild-type (NNNN) ewes. During anoestrus, 96% eCG-treated ewes ovulated, in contrast to 6% treated with MAP alone. The OR of the gonadotrophin-treated females was higher in BNVN and BNNN than NNVN and NNNN ewes. An additive effect in the OR of the two mutations was observed since OR in double heterozygous ewes was similar to the sum of the effects of the alleles of the single heterozygous carrier ewes.

Ewing's sarcoma is a malignant, round cell tumor arising from the bones and primarily affecting children and adolescent, accounting for 3 % of all childhood malignancies. Although the long bones and the trunk are typically affected, rare cases of it involving isolated bones throughout the body have been reported. Involvement of the skull bones is rare, constituting 1-6 % of the total Ewing's sarcoma cases but those affecting the cranial bones are rarer still, constituting only 1 %. We describe an 8 months old infant having Ewing sarcoma, of the petrous and mastoid parts of temporal bone along with the occipital bone, whose clinical presentation mimicked mastoiditis with facial nerve palsy. We discuss the clinical and therapeutic course of an extensive primary Ewing sarcoma of the temporal bone, which was treated without performing surgery and review this entity's literature in detail.

Modern multimodal treatment has significantly increased survival for patients affected by hematologic malignancies, especially in childhood. Following remission, however, the risk of developing a further malignancy is an important issue. The long-term estimated risk of developing a sarcoma as a secondary malignancy is increased severalfold in comparison to the general population. Ewing's sarcoma family encompasses a group of highly aggressive, undifferentiated, intra- and extraosseous, mesenchymal tumors, caused by several types of translocations usually involving the EWSR1 gene. Translocation associated sarcomas, such as Ewing sarcoma, are only rarely encountered as therapy associated secondary tumors. We describe the clinical course and management of three patients from a single institution with Ewing's sarcoma that followed successfully treated lymphoblastic T-cell leukemia or non-Hodgkin lymphoma. The literature on secondary Ewing's sarcoma is summarized and possible pathogenic mechanisms are critically discussed.

In this study, two successive field trials were conducted during the non-breeding season to investigate various factors affecting on fertility of Suffolk ewes after intrauterine insemination with frozen-thawed semen. In the first year (Experiment 1), three sperm numbers per insemination dose (0.25, 0.5 and 1 million sperm) and five sheep farms were used, and in the second year (Experiment 2), parity, age, body weight, body condition score (BCS) and postpartum days were investigated to compare pregnancy and lambing rates. High pregnancy and lambing rates (70.6 and 70.6%, respectively) were obtained with 0.25 million sperm per dose. There were no significant differences in the pregnancy and lambing rates among the five farms, but there was a tendency for one farm to have higher pregnancy (75.8%, P=0.065) and lambing (72.7%, P=0.077) rates than those (46.7-53.3% and 45.2-53.3% for the pregnancy and lambing rates, respectively) of the other farms. In Experiment 2, ewe age significantly affected both the pregnancy and lambing rates. Nulliparous ewes had a higher lambing rate (72.0%) than that (44.2%) of multiparous ewes, but a significant difference was not revealed. Regardless of body weight, BCS tended to be an important factor influencing on fertility of ewes. Body weight and the postpartum days did not affect the fertility of ewes. It was concluded from these results that the fertility of Suffolk ewes after intrauterine insemination with frozen semen was significantly influenced by sperm number per dose and ewe age. Nulliparous ewes at less than three years of age and with a BCS of more than 3.0 are expected to have higher fertility than other ewes.

A greenhouse pot experiment was conducted to evaluate the fertilizer use efficiency of three Syrian rock phosphates in comparison to Mussoorie rock phosphate from India for maize grown in a laterite (ultisol) and an alluvial (entisol) soil amended with sulphur, and using sup 3 sup 2 P-labelled triple superphosphate (TSP). Results showed that application of rock phosphates (RPs) to laterite soil significantly increased the dry matter yields of maize shoots, whereas, in alluvial soil, RPs were not found effective in increasing the yields. Data further indicated that all the three Syrian RPs were equally efficient in increasing dry matter yields in laterite soil and were superior to Mussoorie rock phosphate (MRP). Sulphur added in combination with RPs significantly enhanced the dry matter production as well as 'A' value of alluvial soil. Application of sulphur in conjunction with RPs significantly increased the 'A' value of laterite soil however, sulphur did not contribute to any significant increase in the yields. Syrian RPs were more reactive in soils than Mussoorie RP. (author). 7 refs., 6 tabs

Full Text Available The effect of the presence of a con-specific in the temporal organization of food hoarding was studied in two varieties of Syrian hamster (Mesocricetus auratus: golden and long-haired. Four male hamsters of each variety were used. Their foraging behavior was observed during four individual and four shared trials in which animals were not competing for the same food source or territory. During individual trials, long-haired hamsters consumed food items directly from the food source, transporting and hoarding only remaining pieces. During shared trials, the long-haired variety hoarded food items before consumption, and increased the duration of hoarding trips, food handling in the storage, and cache size. Golden hamsters maintained the same temporal organization of hoarding behavior (i.e., hoarding food items before consumption throughout both individual and shared trials. However, the golden variety increased handling time at the food source and decreased the duration of hoarding trips, the latency of hoarding and storing size throughout the shared trials. In Syrian hamsters, the presence of a con-specific may signal high probability of food source depletion suggesting that social pressures over food availability might facilitate hoarding behavior. Further studies are required to evaluate cost-benefit balance of food hoarding and the role of cache pilferage in this species.

Building upon social psychological work on social identity and mental health, this study among Syrian refugees in Turkey examined the importance of multiple group memberships and identity continuity for mental health and well-being. A survey study was conducted among the very difficult to reach population of Syrian refugees (N = 361). With path analysis in AMOS the associations were examined between multiple group memberships, social identity continuity and mental health and psychological well-being. Indicate that belonging to multiple groups before migration was related to a higher likelihood of having preserved group memberships after migration (i.e., sense of social identity continuity), which, in turn, predicted greater life satisfaction and lower levels of depression. Multiple group membership, however, was also directly related to higher depression. Findings are discussed in relation to the importance of multiple group membership and feelings of identity continuity for refugees.

A striking feature of Ewing sarcoma is the presence of blood lakes lined by tumor cells. The significance of these structures, if any, is unknown. Here, we report that the extent of blood lakes correlates with poor clinical outcomes, whereas variables of angiogenesis do not. We also show that Ewing

Full Text Available Ewes are polyoestrous seasonal animals, however in order to increase their fertility, progesterone derivatives are used by means of impregnated sponges with 20 mg of fluorogestone acetate (FGA. Nevertheless, the use of sponges with FGA generates vaginitis, erythema and interferes with fertility. This paper studies the effect of FGA and sponge over the microbiota vaginal in ewes anestrous. To obtain experimental samples, fifteen ewes anestrous were used. Five ewes were used as control group. Ten ewes anestrous were used and data were collected before, withdrawal and 56 h after withdrawal of sponges with and without FGA, in order to quantify, identify and evaluate changes in the vaginal bacterial microbiota. In the normal microbiota were found Escherichia and Klebsiella strains; however, after removal of the devices, were found enteropathogenic coliform bacterias and some opportunistic as Shigella, Enterobacter, Citrobacter, E. coli, Pseudomonas and Acinetobacter. Also found that the device without FGA, induces a change in the vaginal microbiota, thus, causes vaginitis. In vitro sensitivity tests were performed on the strains identified using twelve different antibiotics; the results showed a higher sensibility to enoxacin, then to the trimethoprim-sulfamethoxazole, ceftriaxone, chloramphenicol and ampicillin. Antibiotics use is necessary to prevent the vaginitis in ewes with dispositive. In conclusion, the intravaginal sponges promote of the vagina inflammation and produce coliform bacteria in vagina.

The objective of this study was to evaluate the effects of chitosan (CHI) supplementation on production performance and blood parameters in dairy ewes. Twenty-four multiparous Latxa dairy ewes at d 16 of lactation were divided into two groups of 12 ewes each. Ewes were fed one of two experimental concentrates (0.840 kg dry matter/d), control or supplemented with 1.2% CHI, on a dry matter basis. Ewes also had free access to tall fescue hay, water, and mineral salts. The experimental period lasted for 25 d, of which the first 14 d were for treatment adaptation and the last 11 d for measurements and samplings. Supplementation with CHI decreased total (p=0.043) and fescue (p=0.035) dry matter intake (DMI), but did not affect concentrate DMI. Supplementation with CHI, moreover, increased plasma glucose (p=0.013) and BUN concentrations (p=0.035), but did not affect those of non-esterified fatty acids. Dietary supplementation with CHI, however, did not affect milk yield, 6.5% FCM, milk composition, or BW, but it improved dietary apparent efficiency by increasing the milk yield-to-DMI (p=0.055) and 6.5% FCM-to-DMI (p=0.045) ratios. In conclusion, dietary supplementation of chitosan maintained ewe performance while reducing feed intake and improving dietary apparent efficiency. (Author)

Full Text Available Since the 1980s, Hizbollah has emerged as the guardian of Lebanon's Shi'a and a stalking horse for Iran. Syria, though allied with Tehran, seeks to manage Hizbollah's freedom of action in Lebanon and is eyed cautiously in Damascus. Hizbollah has managed to maintain independence from these Syrian efforts because of both Lebanese Shi'a religious élan and the protection given Hizbollah by its Shi'a allies in Iran.
