Effect of high hydrostatic pressure freezing on the quality of organic poultry meat

Cilj ovog istraživanja bio je odrediti utjecaj zamrzavanja visokim hidrostatskim tlakom na kvalitetu mesa peradi iz ekološkog uzgoja. Svježi fileti pilećih prsa tretirani su visokim hidrostatskim tlakom (150 MPa/30 min i 250 MPa/60 min) pri -20 °C nakon čega su određeni gubitak na masi, sposobnost vezanja vode, prinos pri kuhanju, te boja i tekstura pilećeg mesa iz ekološkog uzgoja. Dobiveni rezultati pokazuju da tretman visokim hidrostatskim tlakom nije imao značajan utjecaj na gubitak na masi. Viši tlak uzrokuje manji gubitak na masi nego niži tlak, ali i konvencionalne metode zamrzavanja. Povećanjem tlaka smanjuje se sposobnost vezanja vode i prinos pri kuhanju. Porastom tlaka rastu L*, a* i b* vrijednosti. Porastom tlaka povećavaju se tvrdoća, elastičnost i rad potreban za žvakanje mesa.The aim of this study was to determine the effect of high hydrostatic pressure freezing on the quality of organic poultry meat. Fresh fillets of chicken breasts were treated with high hydrostatic pressure (150 MPa/30 min and 250 MPa/60 min) at -20 °C. Drip loss, moisture uptake, cooking yield and color and texture of organic chicken meat were determined. The results show that high pressure freezing treatment did not have a significant effect on drip loss. Higher pressure causes smaller drip loss than lower pressure or conventional freezing methods. By increasing pressure moisture uptake and cooking yield are reduced. Increasing pressure increases L*, a* and b* values. Increasing pressure increases hardness, elasticity and work for mastication of treated organic chicken meat

Pony breeding in Croatia

Od 2003. godine Hrvatski stočarski centar započeo je intenzivno umatičenje poni konja, čime se broj grla u Središnjem popisu konja značajno povećao. Populacija hrvatskog uzgoja ponija fenotipski je i genetski prilično razno-lika, a svojim vanjskim obilježjima najsličnija je grlima pasmine shetland poni. Manjim udjelom javljaju se značajke drugih pasmina ponija. Prema spolu, sve tjelesne izmjere bile su nesignifikantno većih vrijednosti u žen-skih grla, izuzev signifikantno većeg obujma cjevanice u pastuha (P < 0.05). Usporedbom tjelesnih indeksa prema spolu, utvrđena je samo signifikantno veća koščatost pastuha u odnosu na kobile (P < 0.05). Prema prosječnoj visini grebena (99,94 cm) populacija poni konja u Hrvatskoj može se svrstati u skupinu manjih ponija.In 2003 an intensive registration of ponies was started in the Croatian Livestock Center which resulted in a significant in¬crease of the number of ponies in the central register of the Rep¬ublic of Croatia. The population of the Croatian pony is phenotipically and genetically rather diverse and by the exterior charac¬teristics very similar to the Shetland pony. To a smaller degree there are characteristics of other pony breeds. By gender, all body measurements are insignificantly higher in females except for significantly bigger long bone circumference in stallions (P < 0.05). Comparing body indexes per gender only significantly higher boniness has been determined in stallions in relation to females (P < 0.05). By withers height (99.94 cm) pony population in the Republic of Croatia can be classified in the group of small ponies

Breeding systematization of autochthonous horse breed Croatia posavac

Hrvatski posavac je autohtona pasmina konja. Uzgojno područje je prostor Sisačko-moslavačke i dijelom Zagrebačke županije. U cilju dobivanja više podataka o uzgoju kako bi se uzgojni program što uspješnije provodio u 2004. godini započeta je sistematizacija uzgoja hrvatskog posavca. U formiranje rodova u obzir su uzeta isključivo umatičena (žigovana) ženska grla. Rezultat sistematizacije je formiranje 726 rodova kobila s velikom varijacijom u broju kobila prema rodu (2 do 37). Brojno najveći rod kobila s 37 grla je P97, dok je čak 265 rodova brojilo samo 2 kobile. Prosječna veličina progenih grupa umatičenih kobila prema pastuhu iznosila je 9,4 s rasponom varijacije od 1 do 61 kobile kćerke. Kao očevi umatičenih kobila pojavljuju se 484 pastuha, od kojih je 228 umatičenih (20%) a 256 pastuha očeva poznato je samo po imenu (22%). Bez poznatog porijekla po očevoj strani umatičeno je 655 kobila (58 %).Croatian posavac is autochthonous horse breed. Breeding area is the area of the Sisačko-moslavačka county and a part of Zagrebačka county. With a goal of getting more data about breeding so that the breeding program would be successfully conducted, in 2004 the breeding systematization of autochthonous horse breed Croatian posavac has begun. In the line forming, only registered females were taken into consideration. The result of systematization is forming of 726 female lines with great variation in the numbers of mares by the line (2 to 37). Numerously biggest mare line with 37 heads is P97, while even 265 lines counts only 2 mares. The average size of progeny groups of registrated mares by the stallion was 9,4 with variation range from 1 to 61 mare daughter. As the sires of registrated mares there were 484 stallions, from which 228 were registrated (20%) and 256 sires were known only by the name (22%). 655 mares (58%) were registrated wihtout known ancestry by father side

Usporedba stavova i znanja o cijepljenju protiv bolesti COVID-19 studenata Medicinskog fakulteta u Splitu i liječnika obiteljske medicine Splitsko-dalmatinske županije

Glavni cilj ovog istraživanja bio je ispitati razlikuju li se stavovi o cijepljenju protiv bolesti COVID-19 studenata medicine i liječnika obiteljske medicine u Splitsko-dalmatinskoj županiji. Provedeno je presječno istraživanje u kojem je sudjelovalo 176 studenata medicine, 47 studenata dentalne medicine, te 100 liječnika obiteljske medicine. Ispitanici su rješavali anketni upitnik putem Google forms internetske aplikacije tijekom lipnja 2021. Korištena je peterostupanjska Likertova skala koja je sadržavala 27 tvrdnji. Prikupljeni podaci obrađeni su u programima STATISTICA 14 i Python. Utvrđeno je da pozitivan stav o svim cjepivima protiv bolesti COVID-19 ima statistički značajno više liječnika u odnosu na studente (P=0,038). Zadovoljstvo organiziranošću cijepljenja protiv bolesti COVID-19 statistički je značajno veće u liječnika nego studenata (P=0,006). Iako u procijepljenosti između studenata i liječnika nema statistički značajne razlike, ona je pronađena između studenata pretkliničkih i kliničkih godina studija (P=0,005). Udio cijepljenih veći je u studenata kliničkih godina (67%). Također, utvrđeno je, sa statistički značajnom razlikom, da su ispitanici koji su cijepljeni protiv gripe spremniji i na cijepljenje protiv COVID-19 bolesti (P=0,001), te da se značajno više liječnika nego studenata odlučilo na cijepljenje protiv gripe ove ili prethodnih sezona (P<0,001). Studijom je dokazano da su opći stavovi studenata medicinskog fakulteta i liječnika obiteljske medicine o cijepljenju pozitivni. Naime, poznato je da se stavovi pojedinca prema primjeni cjepiva uvelike odražavaju na procijepljenost i incidenciju zaraznih bolesti u populaciji, te je jako važno da i studenti, koji će biti aktivni sudionici zdravstvenog sustava i liječnici obiteljske medicine, koji su najdostupniji sudionici zdravstvenog sustava, imaju jednake stavove o najučinkovitijoj metodi zaštite populacije od širenja zaraznih bolesti

IS THERE A DIFFERENCE IN ATTITUDES TOWARDS VACCINATION AGAINST COVID 19 BETWEEN MEDICAL STUDENTS AND FAMILY MEDICINE DOCTORS IN SPLIT-DALMATIA COUNTY?

Cilj istraživanja: Glavni cilj ovog istraživanja bilo je ispitati razlikuju li se stavovi o cijepljenju protiv COVID-19 bolesti između studenata medicine i liječnika obiteljske medicine u Splitsko-dalmatinskoj županiji. Ispitanici i postupci: Provedeno je presječno istraživanje u kojem je sudjelovalo 176 studenata medicine i 100 liječnika obiteljske medicine. Stavovi i ostale informacije od interesa prikupljeni su rješavanjem anketnog upitnika putem Google forms internetske aplikacije tijekom lipnja 2021. Korištena je peterostupanjska Likertova skala koja je sadržavala 27 tvrdnji. Prikupljeni podaci obrađeni su u programima STATISTICA 14 i Python. Rezultati: Statistički značajno više studenata misli da su na fakultetu dovoljno informirani o COVID-19 bolesti, u odnosu na liječnike (P=0,040), dok statistički značajno više liječnika misli da su na radnom mjestu dovoljno informirani o cjepivima protiv COVID-19 bolesti (P<0,001). Pozitivan stav o svim cjepivima protiv COVID-19 bolesti ima statistički značajno više liječnika u odnosu na studente (P=0,038). Liječnici su izrazili veću zabrinutost za vlastito zdravlje u tijeku pandemije (P<0,001). Zadovoljstvo organiziranošću cijepljenja protiv COVID-19 bolesti statistički je značajno veće u liječnika nego studenata (P=0,006). Iako u procijepljenosti između studenata i liječnika nema statistički značajne razlike, ona je pronađena između studenata pretkliničkih i kliničkih godina studija (P=0,005).

Zaključci: Studijom je pokazano da se stavovi između studenata i liječnika o cijepljenju općenito ne razlikuju, ali liječnici imaju pozitivniji stav prema cjepivima protiv COVID-19 bolesti. Osobe medicinske struke prvenstveno trebaju imati pozitivne stavove o cijepljenju protiv COVID-19 bolesti kako bi mogli biti primjer ostatku populacije.Objectives: The main aim of research was to find out are there any differences in attitudes towards vaccination against COVID-19. Subjects and Methods: Cross-sectional research was conducted in which participated 176 medical students and 100 family medicine doctors. Attitudes and other data of interest was obtained through a survey questionnaire using Google Forms application. The research was conducted through July of year 2021. Data analysis was performed in STATISTICA 14 and Python. Results: Significantly more students thought that they gained enough information about COVID-19, through school programs (P=0.040), while significantly more doctors thought that they gained enough information about COVID-19 vaccine in their work place (P <0.001). Positive attitude towards all COVID-19 vaccines had significantly (P=0.038) more doctors than students. The family medicine doctors are more worried about their health in the times of global pandemic (P<0.001). Significantly more doctors, than students, think that implemented organization of vaccination against COVID-19 was satisfactory (P=0.006). Although there is no statistically significant difference between students and doctors who have already gotten the COVID-19 vaccine, it was found between students of preclinical and clinical years of study (P=0.005). The proportion of vaccinated against COVID-19 is higher amongst students of clinical years of study (67%). Also, it was found, with a statistically significant difference that those who were vaccinated against flu are more willing to be vaccinated against COVID-19 (P=0.001) and that significantly more doctors, than students, decided to take flu vaccine this or previous seasons (P<0.001). Conclusions: This study showed that attitudes about vaccination in general did not differ between medical students and family medicine doctors, and those doctors have more positive attitude towards all COVID-19 vaccines. Medical professionals should primarily have positive attitudes about vaccination against COVID-19 in order to be an example to the rest of the populatio
