ANXIETY OF PATIENTS AT MAGNETIC RESONANCE IMAGING SCREENING

Introduction: Anxiety is a state of feeling helpless and insecure, a state of anticipation and concern that something bad will happen. Fear of pain and the unknown, as well as fear of screening results can increase anxiety. Severe anxiety during magnetic resonance imaging (MRI)can cause patient\u27s movement, leading to poorer imaging and reduction in the quality of the diagnostic test. To determine the anxiety of patients before and after magnetic resonance imaging and to investigate the relationship between the tested anxiety and the socio-demographic characteristics of the patients. Methods: The study was conducted at the Department of Radiology of the University Clinical Hospital Mostar in the period from February 1st 2020 to March 31st 2020. The study included 100 subjects who were prescribed an MRI screening at the time of the study. A socio-demographic questionnaire specifically designed for this study was used to obtain data on subjects such as gender, age, place of residence, smoking, drinking alcohol, economic status, religiosity. The Anxiety Questionnaire as a State-Trait Anxiety Inventory (STAI) was used to examine anxiety. Results: A statistically significantly higher degree of anxiety was determined after MRI screening (p<0.001). Male subjects achieved a statistically significantly higher degree of anxiety before (p=0.019) and after (p=0.034) MRI screening. There were no statistically significant correlations between the age of the subjects and the results achieved on the anxiety tests before and after the MRI screening. Conclusion: Subjects who were prescribed an MRI screening have a statistically significantly higher degree of anxiety after the screening. Male subjects had a statistically significantly higher degree of anxiety on MRI screening

Reproduktivno respiratorni sindrom svinja (PRRS)

Respiratory disease in pigs are major cause of morbidity, mortality, and major cause of economic losses. As results of this situation, it is necessary to carry out timely diagnoses, adequate therapy and on farms established prophylactic measures. Our intention was to show in this paper, production indicators, such as consequence presence of PRRS in pig farms industrial type. The biggest losses in pigs were the first three month of out break in the period from 3-12 month mortality gradually decreased. The costs of prevention and treatment of secondary infections during the 12 month after outbreak of the disease were on average about 40% higher in the period before in relation on period before appear disease. .Bolesti organa za disanje kod svinja su jedan od glavnih uzroka morbiditeta, mortaliteta i jedan od glavnih uzroka ekonomskih gubitaka. Kao rezultat takvog stanja, neophodno je blagovremeno sprovesti dijagnostiku, adekvatnu terapiju i na farmama uvoditi profilaktičke mere. Namera nam je bila da u ovom radu prikažemo proizvodne pokazatelje, kao posledicu prisustva PRRS na farmi svinja industrijskog tipa. Najveći gubici kod tovnih svinja bili su prva 3 meseca od izbijanja zaraze a u periodu od 3-12 meseci mortalitet se postepeno smanjivao. Troškovi prevencije i lečenja sekundarnih infekcija tokom 12 meseci posle izbijanja bolesti bili su u proseku oko 40 procenata veći u odnosu na period pre izbijanja bolesti.

Heritabilitet, fenotipske i genetske korelacije intenziteta porasta i mesnatosti svinja

The five year study included two genotypes of gilts of performance tested gilts, Swedish landrace and crosses F1 generation SLxLY. Of total number (n=3600), 1709 animals were genotype SL and 1891 animals were genotype SLxLY. Measuring of back fat thickness in the loin part (FT1), between 3rd and 4th lumbar vertebrae, 7cm laterally to the back line; back fat thickness (FT2) and depth of the musculus longissimus dorsi (MLD) between the 3rd and 4th rib from the rear, 7cm laterally to the back line. Assessment of meat yield was done using the ultrasonograph apparatus Piglog 105. In regard to meat yield indicators, medium heritability values were established for FT1 h2=0.461, and high values for FT2 h2=0.639, and for meat yield h2=0.633. Low heritability was established for depth of MLD (h2=0.105), life daily gain (h2=0.110) and age at the end of test (h2=0.103). Established phenotypic correlations between fat thickness FT1 and FT2 were strong (rp=0.638); between fat thickness and meat yield very strong (rp=-0.880 to -0.895), and between fat thickness and MLD very weak and negative (rg=-0.103 to -0.216). Genetic correlations were stronger than phenotypic, so between fat thickness FT1 and FT2 the correlation was complete/full (rg=0.930), also between fat thickness and meat yield (rg=-0.979 to -0.982), whereas the correlation between fat thickness and MLD was strong and negative (rg=-0.627 to -0.653). Heritability values for fat thickness and meat yield show that these traits have high level of heritability and are transfered to the progeny, whereas the level and strength of their dependance show that by decreasing the fat thickness positive influences is exhibited on meat yield, and that by increasing of depth of MLD also the meat yield is increased.Petogodišnjim istraživanjem su bila obuhvaćena dva genotipa nazimica švedski landras i melezi F1 generacije ŠLxVJ. Od ukupnog broja (n=3600) istraživanjem je obuhvaćeno 1709 grla genotipa ŠL i 1891 grla genotipa ŠLxVJ. Merenje debljine leđne slanine i dubine musculus longissimus dorsi (MLD) i procena mesnatosti je obavljeno ultrazvučnim aparatom Piglog 105. Za pokazatelje mesnatosti utvrđeni su srednji heritabiliteti za SL1 h2=0,461, a visoki za SL2 h2=0,639, i za mesnatost h2=0,633. Nizak heritabilitet utvrđen je za dubinu MLD-a (h2=0,105), životni dnevni prirast (h2=0,110) i za uzrast (h2=0,103). Utvrđene fenotipske korelacije između debljine slanine SL1 i SL2 su jake (rp=0,638); između debljine slanine i mesnatosti korelacije su vrlo jake (rp=-0,880 do -0,895), dok su između debljine slanine i MLD-a jako slabe i negativne (rg=-0,103 do -0,216). Genetske korelacije su jače od fenotipskih, tako da je između debljine slanine korelacija potpuna (rg=0,930), kao i između debljine slanine i mesnatosti (rg=-0,979 do -0,982), dok je korelacija jaka i negativna između debljine slanine i MLD-a (rg=-0,627 do -0,653).

Metode utvrđivanja stres sindroma junadi i njegov značaj za kvalitet mesa

Methods for determining stress syndrome in beef cattle is of great importance to identify the physiological state of young cattle before slaughter in order for such animals to be properly treated and restored to a normal physiological state. As a consequence of the state of stress prior to slaughter, meat is obtained which is different from normal. These are non-typical post-mortem changes in meat: 'PSE' (pale, soft, exudative) and 'DFD' (dark, firm, dry) meat, 'watery' meat, usually pork, and 'dark' mostly meat of young bulls. Tests were performed on bulls originating from a farm located 50 km from the slaughterhouse and another farm located 150 km from the slaughterhouse. Young bulls were kept in a free system and loading and unloading was done on unloading ramps and animals taken to the boxes using the lane corridor. Also, attention was paid to avoid mixing with unfamiliar animals during transport. The study included 20 males. The same vehicle was used to transport cattle from the farm to the slaughterhouse. The rectal temperature was taken from 20 young bulls, at the time of loading of cattle into a vehicle during transport and immediately before slaughter. The results of measurements of rectal temperature of investigated bulls suggest that prolonging of transport increases the rectal temperature which can serve as an indicator of stress syndrome in bulls. In addition to measuring of rectal temperature as an indicator of bulls' stress syndrome, other methods are still used, such as the measurement of cortisol in saliva and blood, or the latest methods of measuring cortisol in hair. This is the latest method of the 21st century, which can even determine the time of occurrence of stress. This method is the future that will determine whether the stress occurred few days, weeks or even months ago.Metode za utvrđivanje stres sindoma junadi imaju veliki značaj u identifikaciji fiziološkog stanja junadi pre klanja, kako bi se takva grla adekvatno tretirala i povratila u normalno fiziološko stanje. Kao posledica stresnog stanja pre klanja dobija se meso koje se razlikuje od normalnog mesa. Ovo obuhvata netipične postmortalne promene mesa kao što su 'BMV' meso (bledo, mekano i vodnjikavo meso) najčešće svinjsko i 'TTS' (tamno, tvrdo i suvo meso), najčešće juneće meso. Ispitivanja su vršena na junadima koja potiču sa farme udaljene 50 km od klanice i sa druge farme koja je udaljena 150 km od klanice. Junad su držana u slobodnom sistemu a utovar i istovar obavljani su na istovarnoj rampi pri čemu su životinje koridorom odvođene u boksove štala. Takodje se vodilo računa da ne dođe do mešanja nepoznatih životinja u toku transporta. Ukupno je ispitano 20 muških grla. Istim vozilom junad su transportovana od farme do klanice. Rektalna temperatura merena je kod 20 junadi, i to u momentu utovara u stočno vozilo, za vreme transporta i neposredno pre klanja. Rezultati merenja rektalne temperature ispitivane junadi ukazuju da prolongiranjem transporta raste i rektalna temperatura što može poslužiti kao pokazatelj stres sindroma junadi. Pored merenja rektalne temperature kao indikatora stres sindroma junadi danas se koriste i druge metode kao što su merenje kortizola u pljuvački i krvi ili najnovija metoda merenje kortizola iz dlake. Ovo je najnovija metoda 21. veka kojom se čak može odrediti vreme nastanka stresa. Ova metoda predstavlja budućnost kojom će se utvrditi da li je stres nastao pre nekoliko dana, nedelja pa čak i meseci.

Nikšić D., V. Pantelić, D. Ostojić Andrić D. Stanojević, N. Delić, A. Stanojković, M. Petričević (2021). The influence of genetic β-lactoglobulin polymorphism on the quantity and quality of milk of the Simmental breed in Serbia.-Genetika, Vol 53, No.1, 263-270. The study of the link between genes controlling protein polymorphism and milk performance traits of domestic animals has great economic importance from a selection point of view, as it reduces the generation interval, leading to increased productivity in livestock. The objective of this paper was to establish the influence of genetic β-lactoglobulin polymorphism on the quantity and quality of milk of the simmental breed in Serbiа. For the research blood samples were taken from a total of 157 Simmental cows. The genotypes of Simmental cows for β-lactoblobulin and their effect on quantitative milk performance traits were determined using the PCR-RFLP analysis. The variability of traits influenced by the genetic polymorphism of β-lactoblobulin was statistically very highly significant (p 0.05) for content of milk fat and protein. The AB genotype cows achieved a 121 kg and 338 kg increase in milk production compared to the BB genotype and AA genotype cows, respectively

Response of Sinapis nigra L. and Sinapis alba L. to the presence of NaCl and silicon in nutrient solution

Stress caused by salt is one of the most important abiotic stresses for plants. It is well known that silicon can alleviate this abiotic stress in some plant species. In this experiment we analyzed Sinapis nigra and Sinapis alba growing in the presence of 50 and 100 mM NaCl and influence of Si on tolerance of this two species to salinity. The results showed that salinity had significant effect on growth, concentration of photosynthetic pigments and free proline. The smallest effect of NaCl and NaCl combined with Si was on transpiration intensity
