Materials in medicine, vol. 34, issue 6, pp. 27, 2023. Abstract

The present study aimed to evaluate osteogenic potential and biocompatibility of combining biphasic calcium phosphate with zirconia nanoparticles (4Zr TCP/HA) compared to biphasic calcium phosphate (TCP/HA) for reconstruction of induced mandibular defects in dog model. TCP/HA and 4Zr TCP/HA scaffolds were prepared. Morphological, physicochemical, antibacterial, cytocompatibility characterization were tested. In vivo application was performed in 12 dogs where three critical-sized mandibular defects were created in each dog. Bone defects were randomly allocated into: control, TCP/HA, and 4Zr TCP/HA groups. Bone density and bone area percentage were evaluated at 12 weeks using cone-beam computed tomographic, histopathologic, histomorphometric examination. Bone area density was statistically increased (p < 0.001) in TCP/HA and 4Zr TCP/HA groups compared to control group both in sagittal and coronal views. Comparing TCP/HA and 4Zr TCP/HA groups, the increase in bone area density was statistically significant in coronal view (p = 0.002) and sagittal view (p = 0.05). Histopathologic sections of TCP/HA group demonstrated incomplete filling of the defect with osteoid tissue. Doping with zirconia (4Zr TCP/HA group), resulted in statistically significant increase (p < 0.001) in bone formation (as indicated by bone area percentage) and maturation (as confirmed by Masson trichrome staining) compared to TCP/HA group. The newly formed bone was mature and organized with more trabecular thickness and less trabecular space in between. Physicochemical, morphological and bactericidal properties of combining zirconia and TCP/HA were improved. Combining zirconia and TCP/HA resulted in synergistic action with effective osteoinduction, osteoconduction and osteointegration suggesting its suitability to restore damaged bone in clinical practice.

There is a lack of reports describing ultrasonographic and histopathologic features of ocular diseases in donkeys. The present study aimed to document ultrasonographic and histopathologic changes associated with common ocular diseases in donkeys. The study included 45 donkeys (64 eyes) with ocular diseases that had reached the end of their working lives and requested to be used for educational and research purposes. Complete clinical, ophthalmic, ultrasonographic, gross pathologic and histopathologic examinations were included. Ocular abnormalities were documented, tabulated, and analyzed. Seventy-five ocular abnormalities were diagnosed with multiple involvements within the same eye including anterior uveitis (n = 13; 22.8%), cataract (n = 57; 76%), retinal detachment (n = 3; 4%), lens and phthisis bulbi (n = 2; 2.6%). Descriptive ultrasonographic findings of ocular abnormalities were included. Gross pathologic and histopathology findings confirmed the ultrasonography findings. Ultrasonography provided a clinically useful tool offering insight into detailed intraocular structures especially with opacification of the dioptric structures of the eye.

BACKGROUND: Camelids play an important role in the preservation of ecosystems, biodiversity, food security, economic growth, adaptation to climate change, and cultural and social aspects. Therefore, the United Nations has named 2024 the International Year of Camelids (IYC).

AIM: This study aimed to assess the recent progress in camel research and its citation effect as shown in the Scopus database in the IYC.

METHODS: On March 17, 2024, a literature search was done to discover papers indexed in Scopus using the search terms "camel", "camelids", and "". Automatic and manual screening processes were used.

RESULTS: Between 1850 and 2024, a total of 15,844 camelid-related papers were published. Approximately 30% of these documents were released within the previous 5 years (2019-2023). Camel research was included into 28 scientific topics. The top five topics were agricultural and biological sciences, medicine, veterinary science, biochemistry, genetics and molecular biology, immunology, and microbiology. The top five authors in camel research were Faye B, Wernery U, Muyldermans S, Kinne J, and Sahani MS. The top five camel research contributors among 159 academic institutions were from King Saud University, King Faisal University, ICAR-National Research Centre on Camel, Bikane, Cairo University, and United Arab Emirates University. Out of 152 nations active in camel research, the top five were the United States, Saudi Arabia, Egypt, Undefined, and India. The top five languages were English, French, Chinese, Russian, and German. The camel research was financed by 158 sponsors, with the top five being undefined, the National Natural Science Foundation of China, the Deanship of Scientific Research, King Saud University, the National Institutes of Health, and the National Science Foundation. Camel papers have been published under 161 source titles. The top five sources were: Journal of Camel Practice and Research, Tropical Animal Health and Production, Indian Journal of Animal Sciences, Veterinary Parasitology, and Emirates Journal of Food and Agriculture.

CONCLUSION: Although camelids are understudied in scientific studies, there has been a promising increase in camel research over the past 5 years. Furthermore, the IYC may give a unique opportunity to assist scientific research, particularly in low-income countries with large camelid populations.
