Assessment of Genetic Diversity in Moroccan Pomegranate (Punica granatum L.) Collection Using Physicochemical Approaches and Study of Effect of Age Trees
Get PDFAs with other fruit trees, the pomological and chemical characteristics of pomegranate (Punica granatum L.) can vary from year to year and depending on the age of the trees. Physicochemical screening of 19 pomegranate cultivars from a Moroccan ex situ collection, whose fruits were harvested from three different years, showed highly or very highly significant differences for most traits. Indeed, fruit weight, diameter and height were relatively higher in 2017, exceeding the values measured in 2018 by 22.8%, 13.5% and 4%, respectively. The weight and length of the aril, some chemical characteristics such as pH, Brix and maturity index also showed higher values in 2017, exceeding the 2018 values by 3%, 7%, 3%, 14% and 80% respectively. On average over the three harvest years, the 'Chelfi' cultivar had the lowest weight, while the 'Khikhou' variety had the highest value. The weight and yield of the aril varied between 266 mg ('OunH') and 670 mg ('Khik') and 50.65 ('Khik') and 73.34 ('Gord'), respectively. For the chemical parameters, the total soluble solids ranged from 14.52 (Grenade_Jaune) to 17.81 (Sefri 2) °Brix. The maximum value of titratable acidity was found for ‘Negro_Monsteriosa’ (2.87%) and the minimum value for ‘Grenade_Rouge’ (0.37%). The PCA analysis shows the distribution in groups according to the harvest year, which illustrates the annual variance of the characteristics. The hierarchical analysis shows the presence of gene pools with no obvious geographical structure. The results obtained thus provide a basis for the breeding programs of the species
Design, synthesis, and evaluation of a novel fluorescent probe for competitive fluorescence polarization assay to screen galectin-8 inhibitors
Get PDFIn the present work, we describe the design, synthesis, and evaluation of a galectin-8-binding fluorescent probe designed for a competitive fluorescence polarization (FP) assay for screening new galectin-8N inhibitors. The probe was characterized for its photophysical properties and its binding affinity for galectin-8N was determined by using FP. We evaluated the probe in a competitive FP assay with three known galectin-8N inhibitors and demonstrated its suitability for high-throughput screening
Strategies and processes for improving the horizontal mobility of students at the Faculty of Veterinary Medicine in Zagreb
No full textHorizontalna mobilnost omogućuje studentima da tijekom studiranja na matičnom fakultetu upisuju kolegije s drugih studijskih programa unutar Sveučilišta u Zagrebu koji nisu dostupni na njihovom studiju, uz priznavanje položenih ispita i ECTS bodova. Ova praksa obogaćuje iskustva, potiče razvoj kompetencija i fleksibilnost te je ključna za prilagodbu suvremenim društvenim izazovima. U ovom su radu detaljno objašnjeni koraci koje studenti Veterinarskog fakulteta Sveučilišta u Zagrebu trebaju poduzeti, nadležni kontakti, rokovi za podnošenje zahtjeva te uvjeti za priznavanje kolegija na matičnom fakultetu. Cilj je rada olakšati studentima snalaženje u sustavu horizontalne mobilnosti i pružiti Fakultetu alate za kontinuirano poboljšanje ovog obrazovnog procesa. Horizontalna mobilnost time postaje platforma za inovacije, suradnju i jačanje konkurentnosti studenata u obrazovnom i radnom okružju. Naglašena je potreba za transparentnošću procesa i usklađenošću svih sastavnica Sveučilišta s novim smjernicama kako bi se osiguralo učinkovito praćenje i unapređenje sustava horizontalne mobilnosti.Horizontal mobility enables students to enrol in courses from other study programmes within the University of Zagreb that are not available in their primary study programme, with recognition of completed exams and ECTS credits. This practice enriches their experience, fosters the development of competencies and flexibility, and is essential for adapting to modern societal challenges. The paper explains the steps that students of the University of Zagreb, Faculty of Veterinary Medicine, need to take, the relevant contacts, deadlines for submitting applications, and the conditions for course recognition at their home faculty. The paper aims to facilitate students’ navigation within the horizontal mobility system, and provide the Faculty with tools for continuous improvement of this educational process. Horizontal mobility thus becomes a platform for innovation, collaboration, and enhancing students’ competitiveness in academic and professional environments. Emphasis is placed on the need for transparency and alignment among all University components, along with the newly defined guidelines, to ensure effective monitoring and improvement of the horizontal mobility system
Thymoma in a dog
No full textTimus je organ sastavljen od epitelnog i limfoidnog tkiva. Neoplazme timusa mogu nastati iz obiju komponenti, a timomi se razvijaju iz epitelne komponente i obično su benigni. Najčešće sporo rastu, inkapsulirani su i rijetko metastaziraju. Klinički, životinje s timomom pokazuju znakove prisutnosti tvorbe koja zauzima prostor u prsnoj šupljini, poput respiratornog distresa i edema u ventralnom dijelu glave i vrata. Histološki su vrlo varijabilni, što otežava njihovu dijagnostiku i klasifikaciju. U ovom je radu opisan histopatološki nalaz timoma u kuje stare 10 godina. Tumor je dostavljen na histopatološku pretragu u Zavod za veterinarsku patologiju Veterinarskog fakulteta Sveučilišta u Zagrebu.The thymus is an organ composed of epithelial and lymphoid tissue. Thymic neoplasms can arise from both components, and thymomas develop from the epithelial component and are usually benign. They usually grow slowly, are encapsulated and rarely metastasize. Clinically, animals with thymoma have signs consistent with a space-occupying mass in the thoracic cavity, such as respiratory distress, and edema in the ventral part of the head and neck. Histologically, they are very variable, which makes their diagnosis
and classification difficult. This report presents the histopathological finding of a thymoma in a 10-year-old female dog. The tumor was submitted for histopathological examination to the Department of Veterinary

No full textDigital vs. Traditional: Selected Views on Creating Optimal Marketing Communication Mix
No full textPurpose – This study serves as the initial phase of a broader research project. Its aim is to examine age-specific consumer preferences as one of the fundamental starting points for understanding effective marketing communication—particularly from the perspective of the transition from traditional to digital media.
Design/Methodology/Approach – The analysis is based on the empirical research, in which the media preferences of Central European consumers were identified using the CAWI method through a questionnaire distributed to a sample of over 5,000 respondents. To better examine the selected context, graphical representations of differences based on cluster analysis using
the Pearson correlation coefficient were employed.
Findings and Implications – The results indicate that different age groups exhibit distinct preferences for traditional versus digital media. An effective communication mix should be based on a thorough understanding of the target market. The findings show that customers aged 55 and older tend to prefer traditional media, though they can still be effectively reached in the digital space through age-based targeting. Conversely, the data suggests that television is nearing the limits of its effectiveness for consumers under the age of 34. A combined use of communication channels is therefore highly recommended.
Limitations – The main limitation of the research is the local nature of the dataset. However, this does not significantly affect the quality or relevance of the findings.
Originality – By identifying distinct clusters, the study provides a foundation for better understanding the media market from the perspective of the target customer. As the media landscape continues to undergo digital transformation, thorough examination of this shift is essential
Čimbenici koji utječu na zdravo starenje u urbanim i ruralnim sredinama: pregled literature
No full textOvaj pregled literature predstavlja sveobuhvatnu kritičku analizu zdravog starenja u urbanim i ruralnim sredinama, ističući značajne razlike u pristupu zdravstvenoj skrbi, socijalnoj podršci, infrastrukturi, ekonomskim uvjetima te mentalnom zdravlju starijih osoba. Pregledom literature, ustanovljene su sljedeće ključne razlike između urbanih i ruralnih okruženja koje utječu na zdravo starenje: Ruralne sredine suočavaju se s ograničenim pristupom specijaliziranoj zdravstvenoj skrbi, što povećava ranjivost starijih osoba s kroničnim bolestima. Društvena podrška snažnija je u ruralnim zajednicama zbog veće društvene kohezije, dok urbane sredine pružaju bolje organizirane mreže podrške. Urbana područja nude bolju infrastrukturu i javne prostore za tjelesnu aktivnost, ali veća gustoća stanovništva može negativno utjecati na mentalno zdravlje starijih osoba. Starije osobe u ruralnim područjima suočavaju se s većim ekonomskim izazovima zbog nižih prihoda, što utječe na njihov pristup osnovnim potrebama i kvaliteti života. Viša razina depresije i anksioznosti primijećena je u urbanim sredinama, dok ruralna područja pružaju bolje uvjete za mentalnu dobrobit zbog manjeg stresa i većeg osjećaja zajedništva. Zdravo starenje može se postići u oba okruženja kroz ciljani pristup koji uključuje unaprjeđenje zdravstvene skrbi, drušvene podrške, infrastrukture i politika. Ulaganjem u ove ključne aspekte možemo stvoriti zajednice koje podržavaju aktivno, zdravo i dostojanstveno starenje za sve starije osobe
#Challenge Accepted: Adolescents' Perception of Motivation Behind Social Media Challenges
No full textTehnološki napredak i sve veća važnost interneta učinili su
izazove na društvenim mrežama uobičajenom praksom
među adolescentima. Unatoč njihovoj raširenosti, rijetka su
istraživanja na ovu temu. Ovo istraživanje proučava kako
adolescenti doživljavaju motive svojih vršnjaka za
uključivanje u online izazove. Sudjelovala su 43 učenika u
šest fokusnih grupa. Rezultati ističu teme poput
(samo)poštovanja, potrebe za pripadanjem, motive vezane
za regulaciju emocija, traženja uzbuđenja i razvoj online
identiteta. Adolescenti kao ključne čimbenike izdvajaju
popularnost, zabavu i vršnjački pritisak. Od izvanredne je
važnosti podizanje svijesti učenika, roditelja i nastavnika o
učinku izazova na društvenim mrežama na svakodnevni
život mladih.Technological progress and the Internet's growing importance
have made social media challenges common among
adolescents. Despite their prevalence, research on this topic
remains scarce. This study explores how adolescents perceive
their peers' motivation for participating in social media
challenges. Forty-three students in six focus groups participated.
The results highlight themes such as the need for (self-)respect,
the need for love and belonging, motives related to emotion
regulation and sensation seeking, and the pursuit of online
identity development. Adolescents emphasise popularity, fun,
and peer pressure as key factors. Raising awareness about the
impact of social media challenges on young people's daily lives
among students, parents, and educators, is crucial
Some Aspects of Middle Childhood in Croatia and Well-Being of Children from a Parental Perspective
No full textCilj provedenoga kvalitativnog istraživanja jest ispitati percepciju
roditelja djece u srednjem djetinjstvu o važnosti te pozitivnim i
negativnim stranama upotrebe digitalne tehnologije, njegovanja
literarnog okruženja te bavljenja fizičkom aktivnošću za dobrobit
djece, kao i percepciju razlika u roditeljstvu nekada i danas. U
istraživanju je sudjelovalo 40 roditelja u 9 online fokus-grupa.
Rezultati tematske analize pokazuju kako se sudionici slažu da
sve tri vrste okoline imaju neke pozitivne utjecaje na dobrobit
djeteta. Kada je u pitanju digitalna tehnologija, sudionici navode
i određene negativne posljedice te određene poteškoće s kojima
se susreću kada nastoje djecu uključiti u organizirane sportske
aktivnosti. Kao razliku u roditeljstvu nekada i danas, ističu
znatno veći nadzor nad djecom, kao i uključenost u
organiziranje slobodnoga vremena. Dobiveni rezultati
omogućuju kreiranje daljnjih kvantitativnih istraživanja roditeljske
percepcije o važnosti okoline za dobrobit djeteta, kao i za
kreiranje intervencija kojima se olakšava izlaganje djece
pojedinoj okolini.This qualitative study aims to examine the perception of the
importance, and positive and negative aspects of digital
technology use, physical activity, and literacy environment for
the well-being of children in middle childhood, as well as
perceived differences in parenting between generations. The
study included 40 parents (25 mothers and 15 fathers) in 9
online focus groups. The results show that participants agree
on the positive influence of all three environments on child
well-being. They also recognise some negative aspects of
digital technology use and the difficulties they encounter in
trying to ensure their children's participation in organised
sports activities. As for differences in parenting between
generations, they mention more supervision displayed by
today's parents and greater involvement in leisure time
organisation. The results enable future quantitative studies on
the parental perception of environmental influences on
children's well-being and the creation of interventions aimed
at removing obstacles that prevent parents from engaging
their children in certain activities
