ABSTRACTTwo experiments are described investigating the possibility of advancing puberty in Awassi ewe lambs kept under semi-arid conditions in mid Syria using 197 single ewe lambs in 1982 and 165 in 1984. In both years, the animals were allocated to three groups each given different levels of supplementation with a barley/chopped straw mixture to achieve different levels of pre-mating growth (high, medium and low). In 1984, the three groups were further subdivided into four subgroups each given continuous exposure to teaser rams from different ages. These were 175, 200 and 230 days of age and a control group not given continuous access to the ram. The results for the two experiments showed that a higher proportion of ewe lambs on the high and medium treatments showed oestrus in their first season (H = 88%, M = 72%, L = 41%; P < 0·01). The high level of nutrition also advanced the mean date of first oestrus in the high group by 22 and the age at conception by 16·5 days as compared with the low level.In the second experiment, no interaction between feeding level and presence of ram was observed and although there were no significant effects on occurrence of oestrus, continuous exposure to vasectomized rams from 175 days reduced mean age at first oestrus by 16 and age at conception by 19 days as compared with the unexposed controls.It is concluded that these practices have important implications for the efficient use of semi-arid range land by Awassi sheep on a semi-intensive system.

SummaryRectal, external auditory meatus and skin temperatures and panting rates were measured in native fat-tailed Awassi and imported German Mutton Merino (GMM) sheep. The Awassi evolved under desert conditions, have a localized fat deposit, coarse carpet wool, long pendulous ears and long, spiral horns (males). In contrast, the GMM evolved under temperate conditions, have well-distributed fat, medium fine wool, short, straight ears and are polled. The study was carried out during the summer in the northern part of the Negev desert.The mean daily rectal temperature fluctuation was higher (P < 0·01) in the GMM than in the Awassi (1·78 °C v. 1·08 °C). The external auditory meatus temperature was lower than the rectal temperature by 1·5 °C in the GMM and by 1·7 °C in the Awassi, indicating a cooler brain temperature. The maximum skin temperature was similar to the maximum rectal temperature in both breeds, thus sweating was of little importance. The panting rate of the GMM increased fivefold (40·6–199·4 pants/min) whilst the rate of the Awassi increased fourfold (35·3–135·0 pants/min). There was no between-breed difference in either the rectal temperature or panting rate until 25–30 °C ambient temperature and it is thought that the higher rectal temperature of the GMM at this ambient temperature might have triggered off the higher panting rate. It seems that the GMM use panting to a greater extent than the Awassi whereas the Awassi dissipate heat through the skin more efficiently than the GMM. It is concluded that both breeds are thermostable, much of the between-breed difference in rectal temperature can be attributed to their anatomical differences.

SUMMARYA study was made of the effects of different levels of nutrition between 3 and 6 months and between 6 and 12 months of age on subsequent growth to mature size, longevity and lifetime production of Scottish Blackface female sheep on a hill farm. Treatment differences between 3 and 6 months were small and resulted in only a 3 kg live-weight advantage for the animals receiving a high level of feeding. Treatment differences between 6 and 12 months were considerable and resulted in a mean 14 kg advantage for animals receiving a high level of feeding. Those animals remained significantly heavier until 42 months of age and significantly larger, as depicted by skeletal measurements, until 54 months of age.A high level of feeding between 3 and 6 months of age had no significant long-term effect on wool growth ewe survival or lifetime lamb production, whereas a high level of feeding between 6 and 12 months of age had a significant positive effect on the mean number of lambs born per ewe over five lamb crops. This effect was not maintained to weaning, due to an apparently greater lamb mortality. Treatment effects on ewe survival and on flock lifetime production, although considerable, were not statistically different.It is concluded that any advantages of improved feeding during rearing were largely lost through the inadequacy of the adult nutritional environment and only when the latter was not limiting would higher standards of rearing be justified.

During qualified sport selection special attention should be paid to those features and abilities that have a great influence on the effectiveness, and those, that are mainly under the influence of genetic factor. Such morphogenetic markers of sports selection include, firstly, the constitutional features of athletes, in particular the shape of the chest. The purpose of work is to determine the differences between the anthropometric dimensions of the chest between female volleyball players of high level of athletic skill and non-sportsmen, who belonged to different constitutional types. On the base of the Scientific-Research Center of the Vinnytsya National Pirogov Memorial Medical University an anthropo-somatotypological investigation of 113 female volleyball players of high level athletic skill (from 16 to 20 years old) was done. The control group included 204 practically healthy young women, who were not engaged in sports of the corresponding age. Anthropometric research was performed according to the V. V. Bunak (1941) method, somatotypological study was based on the estimated modification of the Heath-Carter method (1990). In young women, who were not engaged in sports, more than in half of the cases were indicated constitutional types, which were characterized by good development of fatty body composition. Between female volleyball players were dominated individuals with mesomorphic somatotype (26.66%), ectomorphic somatotype (23.01%), ecto-mesomorphic somatotype (23.89%), and representatives of the intermediate somatotype (23.01%) were almost uniformly represented in the sample. The analysis of the results was carried out in the licensing program "Statistica 5.5" using nonparametric methods of estimating the parameters. We have found that the female volleyball players of the ectomorphic somatotype have the smallest anthropometric dimensions of the chest, as compared with athletes of other constitutional groups. In the mesomorphs female volleyball players all transverse and the most of overall sizes of the chest were the largest. Parameters of the athletes with the ecto-mesomorphic somatotype were slightly small to the size of the somatometric parameters of the mesomorphs, but they had the highest values of the anterior-posterior size of the chest. Female volleyball players with intermediate somatotype had larger values of the chest size than volleyball players with ectomorphic somatotype, although no significant difference was found when comparing them. It was found, that the most of the overall, transverse, and anterior-posterior dimensions of the chest in female volleyball players are statistically significantly higher than that of girls, who were not engaged in sports, and belonged to the same constitutional type as athletes. We have made a conclusion that belonging to one of the constitutional type does not provide similarity of morphometric parameters of the chest in persons with different levels of physical activity.

<p>This paper aims to evaluate the influence of different levels of supplemental product-dehydrated cashew in the feed for crossbred Girolando cows on milk production and hemato-biochemical profile. The experiments were conducted using eight cows that were randomly distributed in a Latin square design (4×4), in which treatments consisted of four supplementation levels with product-dehydrated cashew (PDC) in animal diets, namely: 0% PDC (control diet), 1.0 kg of DCP, 1.5 kg of PDC and 2.0 kg of PDC in total dry matter . The milk and animals were weighed and the body condition of the animals were evaluated within seven days of milk collection during each experimental period. To determine the serum biochemistry and blood count of cows, three blood samples were taken in each period, at 7, 14 and 21 days before the daily supply of supplementation with samples collected from 5 ml of blood by puncturing the jugular vein. Supplementation with 2 kg of PDC reduced milk production and the levels of glucose and total plasma protein compared to the control group, due to the higher level of tannin in this group. Supplementation with PDC raised the total count of the erythrocytes, reduced the mean corpuscular volume (MCV) and non-changed number of leukocytes. Increased levels of phenolic compounds in the diet inhibited the absorption of dietary proteins, which decreased milk production.</p>

Abstract Background: Safety protocols are usually neglected among most of the TNT exposed population, therefore, rendering the community prone to various occupational hazards. The current study highlights ring shaped cataract and urinary metabolites of TNT among TNT exposed population (n=26) against a control group (n=20).Methods: An observational case-control study was carried out in two groups: 300 subjects exposed to TNT in Dir and Bajour Agency, Pakistan and a control group from the base hospital. We determined the presence of ring shaped cataract and urine metabolites of TNT using slit lamp biomicroscope and gas chromatography mass spectrometric analysis respectively.Results: Results substantiate a high level of urine metabolites for exposed subjects compared to the control group (p<0.001). Age had no significant effect on (p>0.05) on presence of ring shaped cataract and the level of urinary metabolites of TNT, while duration of exposure showed significant effect (p<0.001). Females showed high incidence of ring shaped cataract and urinary metabolites of TNT than men ( p<0.001). The mean age of the exposed subjects was 51±14.38 (Mean+SD) years. The mean year of exposure was 49±5 (Mean+SD) years,Conclusion: This study showed TNT as a risk factor for the presence of ring-shaped cataract among TNT exposed group in Pakistan. It is important to screen exposed community for the presence of ring-shaped cataract, and pre-clinical identification of TNT adducts to prevent systemic complications.

The study was conducted to determine the effects of packing on some haematological responses in the one-humped camel (Camelus dromedarius) during the harmattan season in the semi-arid zone of Nigeria. The study was conducted using 8 experimental camels which were packed with bags of grains of 200 kg, while 4 camels served as the control group only trekked but were not packed. Ambient temperature (AT) and relative humidity (RH) of the experimental site were recorded three days prior to the experiment and on the experimental day at 06.00 h, 12.00 h and 15.00 h. Some haematological parameters were determined in all the camels. The mean AT and RH values ranged between 22-36.50 ºC and 26-36 %, respectively. The erythrocyte count, TP and PCV values were significantly higher (P < 0.05) in experimental camels than control camels after the experiment. The changes recorded in some of the parameters demonstrated that compensatory mechanisms were adopted by the camels to reduce the adverse effects of stress of packing. It is therefore recommended that a potent antioxidant should be administered to camels before subjecting them to packing to ameliorate the effects of stress of packing.

Image analysis systems have been increasingly utilized for the assessment of plant growth and health for decades. We used in this study the software Mesurim Pro to evaluate the variation of the leaf reflectance at Red, Green and Blue and the variation of the senescence parameters. The analysis of variance revealed that the reflectance at different wavelengths (Red, Blue and Green) was highly significant genotypes effects (P 0.001); for this parameter the good genotypes are those we have the lowest values such as G19. In addition, the preferable genotypes were those which have low values for the mean senescence and senescence velocity; based on this raison the best genotype was the introduce genotype G12. The genotypes effect was significant for the grain yield and thousand-kernel weight, for the chlorophyll content and the analysis of variance showed a significant effect of genotypes, the highest values registered by the introduced genotype G5 this one was in the same homogenize group of G2, G4, G8 and G18. The ranking of genotypes based on all parameters suggested that the genotypes G11, G12, G5, G15 and G18, respectively (introduce genotypes) were the ideal genotypes under these conditions.

Abstract Recently, a JAK2V617F mutation has been described in the majority of patients with polycythemia vera (PV), and in a subset of patients with essential thromocythemia (ET) and idiopathic myelofibrosis (IMF). Similarly, PRV-1 has been found overexpressed in many of these patients. The aim of the study was to correlate PRV-1 and WT1 expression with the presence of JAK2 mutation in order to establish whether these markers identify the same subset of patients. Using a Real Time PCR we studied the expression level of PRV1 and WT1 in 330 patients including 26 IMF, 156 PV, 122 ET, 16 HES. 10 familiar forms of PV were included. In addition a control group of 50 healthy subject and 60 reactive conditions were studied All the patients were analyzed for the presence of JAK2 mutation using the ABI Prims 3100 genetic analyzer. We found that JAK2 mutation was present in 50 % of IMF, 93% of PV and 55% of ET and 6% of HES. PRV-1 was increased in 84% of IMF, 98% of PV and 90% of ET and it was not increased in HES. WT1 was increased in 99% of IMF, 45% of PV and 42% of ET and 100% of HES. No mutations of JAK2 were detected in normal subjects or in reactive conditions. Both WT1 and PRV1 were expressed at low levels in normal subject (for PRV1 the mean value of 2-Delta Delta Ct was 2,05; range 0,05–5,46; for WT1 mean value WT1 copies/104 ABL copies of 4; range 0–20). The mean value of WT1 copies/104 ABL copies in IMF was 306 (p=0,00004 compared to normal controls), in PV was 156 (p=0,0001), in ET was 202 (p=0,0002) and in HES was 161 (p=0,0004). PRV1 mean value in IMF was 144 expressed as 2−Delta Delta Ct, and it was 423 in PV and 290 in ET. Moreover the correlation between the three markers allowed to establish that both WT1 and PRV1 were higher in JAK2 mutated samples when compared to wild type JAK2 with a p value of 0,001 for WT1 and 0,004 for PRV1. In spite of these we were able to identify a subset of patients affected by IFM characterized by increased values of PRV1 and WT1 but not by JAK2 mutation (34%) and a small subset 15% characterized only by WT1 overexpression. Only 5% of PV and 35% of ET patients expressed only PRV-1 but not JAK2 mutation and WT1 expression. HES patients overexpressed WT1 but not PRV1 and only one patient presented the JAK2 mutation. Finally 10 patients affected by familiar form of PV were studied. All the subjects showed normal PRV-1 expression but high level of WT1 transcript and 9 out of 10 presented the JAK2 mutation. This study demonstrates that the combination of all these markers is probably useful for a correct diagnosis of these patients but further studies are required to stratify these patients and to better classify them according to the presence of molecular lesions.

Background and Objectives The 10-item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) is a recently developed questionnaire for assessing both nasal obstruction and nasal cosmetic satisfaction. It is widely used in rhinoplasty clinics based on its high level of reliability and efficacy in Western countries. In this study we evaluated the validity of the Korean version of the SCHNOS (K-SCHNOS).Subjects and Method The SCHNOS was translated into easily-understandable Korean following the guideline of the developers. Twenty-seven patients undergoing rhinoplasty and a control group of 29 non-rhinoplasty patients completed K-SCHNOS twice at intervals of 2 weeks regardless of pre- or postoperative state. The K-SCHNOS was evaluated for internal consistency, test-retest reliability, and validity.Results Of the 56 study participants, 39 (69.6%) were male and 17 (30.4%) were female, with the mean (standard deviation) age of 33.5 (12.9) years. Both obstructive domain and cosmetic domains showed high internal consistency with their respective Cronbach’α values being 0.92 and 0.91. The correlations in the test-retest analysis for each item were acceptable, ranging from 0.6-0.82. The association between the obstructive domain and cosmetic domain was 0.48 (95% confidence interval, 0.32-0.61), indicating a very weak correlation.Conclusion The K-SCHNOS has proven to be a reliable and valid questionnaire to be used by Korean-speaking patients undergoing functional or cosmetic rhinoplasty.
