Foot tumors are a rare occurrence, which can make diagnosis and management difficult. Certain benign tumors can be locally aggressive, with a rapid progression resembling a malignancy. We present a case of bizarre parosteal chondromatous proliferative (BPOP) lesion, also known as Nora lesion, arising from the sesamoid. This is a benign lesion with overlapping clinical and radiological features of a malignant neoplasm. Highlighting classic BPOP characteristics is crucial in avoiding potentially incorrect management and resulting morbidity. Levels of evidence IV; Therapeutic studies; Case Report

The neuronal cell adhesion molecule contactin-4 (CNTN4) is genetically associated with autism spectrum disorder (ASD) and other psychiatric disorders. Cntn4-deficient mouse models have previously shown that CNTN4 plays important roles in axon guidance and synaptic plasticity in the hippocampus. However, the pathogenesis and functional role of CNTN4 in the cortex has not yet been investigated. Our study found a reduction in cortical thickness in the motor cortex of Cntn4 −/− mice, but cortical cell migration and differentiation were unaffected. Significant morphological changes were observed in neurons in the M1 region of the motor cortex, indicating that CNTN4 is also involved in the morphology and spine density of neurons in the motor cortex. Furthermore, mass spectrometry analysis identified an interaction partner for CNTN4, confirming an interaction between CNTN4 and amyloid-precursor protein (APP). Knockout human cells for CNTN4 and/or APP revealed a relationship between CNTN4 and APP. This study demonstrates that CNTN4 contributes to cortical development and that binding and interplay with APP controls neural elongation. This is an important finding for understanding the physiological function of APP, a key protein for Alzheimer’s disease. The binding between CNTN4 and APP, which is involved in neurodevelopment, is essential for healthy nerve outgrowth.

Introduction Cerebrovascular insult (CVI) in patients with psychiatric diseases is to a large extent more prevalent and is accompanied by a worse prognosis after a incident. Despite the higher mortality, these patients are less frequently subjected to CT angiography and interventional intervention on the blood vessels of the brain. Objectives To show the frequency of cerebrovascular insults in patients with schizophrenia (SCH), bipolar affective disorder (BP), and depression, depending on age, gender, socioeconomic characteristics, professional qualifications, and dietary habits. Methods A total of 1200 patients with SCH, BD and depression were treated over a period of five years. Results 11.1% SCH patients had CVI and 3,7% a cases of bipolar afective diseases. CVI was most often experienced by patients who were married, employed, or retired, and who lived in urban areas. Smoking, elevated blood pressure values, elevated BMI do not have a significant impact on the occurrence of CVI in all groups. Patients with elevated values of glucose, total cholesterol and LDL cholesterol and CRP had a higher incidence of cerebrovascular insult. Conclusions It is necessary to work on raising the awareness of people suffering from psychiatric diseases regarding lifestyle and eating habits, and to conduct periodic health examinations. It is important to recognize high-risk patients and educate them about preventive measures. Disclosure of Interest None Declared

Introduction The introduction of antipsychotics, especialy of newer generation, greatly a”ects the e”ectiveness of the psychiatric treatment of patients with schizophrenia (SCH) and bipolar disorder (BP). Patients su”ering from SCH and BP often have metabolic syndrome (MetSy), as a result of taking antipsychotic therapy, especially in patients with abdominal obesity, there is an atherogenic fat profile that carries a high risk for the development of dyslipidemia. Objectives To investigate frequency and di”erences of somatic diseases in patients with SCH and BD depending on the presence of MetSy. Methods This five-year prospective study was conducted in the Psychiatric Hospital of Canton Sarajevo. We followed 135 patients with SCH and 135 patients with BD, aged 30 to 69 years, who were treated with antipsychotics for five years. Results Dyslipidemia was significantly more common in SCH patients (73.3%), compared to BD (54.1%) and was dominantly presented in women (61.4%). The frequency of dyslipidemia increased with the age of the patient. Associated risk factors in patients with SCH diagnosed with dyslipidemia were 73.5% smokers, 78.7% hypertensive patients, 69.7% patients with elevated BMI and 83.0% with elevated blood glucose values, while slightly lower values were recorded patients with BP. 97.8% of patients with dyslipidemia had elevated CRP. Conclusions There are significant di”erences in dyslipidemia in patients su”ering from SCH and BP. Adequate knowledge of the antipsychotic drugs is required in order to provide adequate psychiatric treatment, regarding minimalising adverse e”ects of antipsychotics will be reduced to a minimum. It is important to recognize high-risk patients and educate them about preventive measures. Disclosure of Interest None Declared

Abstract Background Crimean–Congo haemorrhagic fever (CCHF) is a widespread tick‐borne zoonosis with reported detection of virus and/or virus‐specific antibodies from over 57 countries across Africa, Asia, Europe and the Middle East and is endemic in the Balkans. Detection of Crimean–Congo Haemorrhagic Fever Virus (CCHFV) antibodies in domestic ruminants has been important in providing initial evidence of virus circulation and in localising CCHFV high‐risk spots for human infection. Objectives The present study investigated the possible exposure of sheep to CCHFV in Bosnia and Herzegovina (B&H). Methods To investigate the presence of anti‐CCHFV antibodies in sheep, all sera (n = 176) were tested using multi‐species double antigen enzyme‐linked immunosorbent assay (ELISA). Reactive sera were further complementary tested by adapted commercial indirect immunofluorescence assay (IFA) using FITC‐conjugated protein G instead of anti‐human immunoglobulins. Results CCHFV specific antibodies were detected in 17 (9.66%) animals using ELISA test. All negative sera were determined as negative by both tests, while 13 out of 17 ELISA‐positive reactors were also determined as unambiguously positive by IFA test. The age group with the highest proportion of seropositive rectors were the oldest animals. Conclusions This is the first report of anti‐CCHFV antibodies in sheep from B&H providing the evidence of CCHFV circulation in the country's sheep population. So far, these findings indicate the circulation of the virus in the westernmost region of the Balkans and point to the potential CCHFV spread further out of this endemic area.

Abstract Neurodevelopmental and neuropsychiatric disorders, such as autism spectrum disorders (ASD), anorexia nervosa (AN), Alzheimer’s disease (AD), and schizophrenia (SZ), are heterogeneous brain disorders with unknown etiology. Genome wide studies have revealed a wide variety of risk genes for these disorders, indicating a biological link between genetic signaling pathways and brain pathology. A unique risk gene is Contactin 4 (Cntn4), an Ig cell adhesion molecule (IgCAM) gene, which has been associated with several neuropsychiatric disorders including ASD, AN, AD, and SZ. Here, we investigated the Cntn4 gene knockout (KO) mouse model to determine whether memory dysfunction and altered brain plasticity, common neuropsychiatric symptoms, are affected by Cntn4 genetic disruption. For that purpose, we tested if Cntn4 genetic disruption affects CA1 synaptic transmission and the ability to induce LTP in hippocampal slices. Stimulation in CA1 striatum radiatum significantly decreased synaptic potentiation in slices of Cntn4 KO mice. Neuroanatomical analyses showed abnormal dendritic arborization and spines of hippocampal CA1 neurons. Short- and long-term recognition memory, spatial memory, and fear conditioning responses were also assessed. These behavioral studies showed increased contextual fear conditioning in heterozygous and homozygous KO mice, quantified by a gene-dose dependent increase in freezing response. In comparison to wild-type mice, Cntn4-deficient animals froze significantly longer and groomed more, indicative of increased stress responsiveness under these test conditions. Our electrophysiological, neuro-anatomical, and behavioral results in Cntn4 KO mice suggest that Cntn4 has important functions related to fear memory possibly in association with the neuronal morphological and synaptic plasticity changes in hippocampus CA1 neurons.

Objective: The objective of the study was to assess the behavioral attributes of primiparous and multiparous Friesland, Jersey, and Crossbred cows around calving time in a pasture-based dairy system. Material and methods: A total of 120 pregnant cows were used in the study, comprising of 40 cows per genotype in different parities [A-primiparous (n = 10), B-2 to 4 (n = 10), C-5 and 6 (n = 10), and D-7 and 8 (n = 10)] and kept in a maternity paddock. Five observers monitored cows from the onset of parturition until the calves were fully expelled, recording the frequency and duration of lying, standing, and walking bouts, calf licking, and suckling. Results: There were differences (p < 0.05) observed in the behavioral patterns around the time of calving. Jersey multiparous cows spent (p < 0.05) significantly most of their time (20.50 ± 3.10) in lying position as compared to the other genotypes. The Jersey cows also spent most (p < 0.05) of their time (48.00 ± 0.34) in a standing position during the calving period. Friesland cows spent (p < 0.05) most of their time (12.00 ± 1.19) exhibiting either stepping or walking attributes as compared to Jersey and Crossbred cows. The Jersey genotype spent significantly (p < 0.05) more time (123.00 ± 10.43) in expelling their calves compared to the other genotypes. There was a significant (p < 0.05) interaction between genotypes and parity on time spent by cows on licking their calves. There was a significant difference (p < 0.05) observed between the genotypes of the primiparous cow. Conclusion: The primiparous cows spent most of their time in standing and the least amount of time in other activities throughout the trial due to the lack of maternal experience. The current study revealed that behavioral activities differ according to genotype and parity. [J Adv Vet Anim Res 2020; 7(2.000): 290-298]

Transfer RNAs (tRNAs) are highly abundant species and, along their biosynthetic and functional path, they establish interactions with a plethora of proteins. The high number of nucleobase modifications in tRNAs renders conventional RNA quantification approaches unsuitable to study protein-tRNA interactions and their associated functional roles in the cell. We present an immunoprecipitation-based approach to quantify tRNA bound to its interacting protein partner(s). The tRNA-protein complexes are immunoprecipitated from cells or tissues and tRNAs are identified by northern blot and quantified by tRNA-specific fluorescent labeling. The tRNA interacting protein is quantified by an automated western blot and the tRNA amount is presented per unit of the interacting protein. We tested the approach to quantify tRNAGly associated with mutant glycyl-tRNA-synthetase implicated in Charcot-Marie-Tooth disease. This simple and versatile protocol can be easily adapted to any other tRNA binding proteins.Graphic abstract: Figure 1. Schematic of the tRNA-Immunoprecipitation approach.

Background: With exception of the desert biome, all of South Africa’s biomes occur in the Eastern Cape. The province is known to have high numbers of livestock that are mostly found in communal farming areas. Multi-drug resistance of gastrointestinal nematodes against major classes of conventional anthelmintics and the high cost of synthetic drugs calls for an urgent search for different control strategies of nematodes. Aim: A survey was conducted to identify and document plant species used to control gastrointestinal nematodes of livestock in Ciko, Goso and Upper Ngqumeya communities in the Eastern Cape Province. Setting: The study included filed observations and transect walks, as well as a standardized questionnaire given to 48 sheep farmers. Methodology: Forty-eight livestock farmers including men and women of mixed ages were interviewed. The information was obtained through the use of a structured questionnaire, field observations and transect walks. Data generated were analysed using descriptive statistics with frequency of citation (FC) and relative frequency of citation (RFC) as quantitative. Results: A total of 11 plant species from different genera were reportedly available and used to control gastrointestinal nematodes. Aloe ferox (0.67) and Zanthoxylum capense (0.44) had the highest values of RFC followed by Strychnos henningsii (0.23) and Elaphantorhhiza elephantine (0.21) and were widely known by the people of the study areas. The three most frequently used plant parts were leaves, roots and bark accounting for about 36.4%, 27.3% and 27.3%, respectively. The ethnoveterinary medicines were prepared in the form of decoctions and infusions. Oral administration of the concoctions was the only route of administration. The major constraints of sheep production as perceived by the farmers were prevalence of internal (36%) and external parasites (18.1%). All medicinal plants used were native and collected from the wild. The most dominant life forms were trees (45.4%), followed by herbs (36.4%) and shrubs (18.2%). Homestead expansion was ranked as the major threat (26%) to medicinal plants followed by firewood (21%). In-situ (protection through rangers) was the most frequently mentioned (67%) conservation practice used by farmers to protect the loss of medicinal plants followed by ex-situ (33%). Conclusion: In the light of data gathered on the surveyed plants, it appeared the plants play a role in the healthcare of sheep in rural communities. Further studies are required to analyse the plants for their chemical composition and biological properties.

Abstract Background The prime significance of species belonging to the genus Culicoides Latreille, 1809 (Diptera: Ceratopogonidae) is their ability to transmit viruses such as bluetongue virus (BTV) to wild and domestic ruminants. Prior to 1998, BTV was considered exotic in Europe, but according to recent history of its outbreaks, it has become endemic in southern and eastern European countries circulating beyond its expected historical limits, into the Balkan region. The wind-borne long-distance dispersal of Culicoides spp. over water bodies and local spreading between farms emphasize the necessity of filling in the information gaps regarding vector species distribution. In most Balkan countries, data on Culicoides fauna and species distribution are lacking, or information is old and scarce. Results During this study, 8586 specimens belonging to 41 species were collected. We present the first faunistic data on Culicoides species in the former Yugoslav Republic of Macedonia (FYROM), Kosovo, Montenegro and Serbia. For other countries (Bosnia and Herzegovina, Bulgaria and Croatia), all historical records were compiled for the first time and then expanded with our findings to various extents. In all countries, confirmed or suspected BTV vector species belonging to the subgenera Avaritia and Culicoides were collected. The total number of species sampled during our field collections was 20 in Bosnia and Herzegovina (15 new records), 10 in Bulgaria (2 new records), 10 in Croatia (5 new records), 13 in FYROM, 9 in Kosovo, 15 in Montenegro, and 28 in Serbia. Of these, 14 species were registered for the first time in this part of the Balkans. Conclusions This paper provides the first data about Culicoides fauna in FYROM, Kosovo, Montenegro and Serbia, as well as new records and an update on the checklists for Bosnia and Herzegovina, Bulgaria and Croatia. These findings provide preliminary insights into the routes of BTV introduction and spreading within the Balkans, and present a valuable contribution to further research related to Culicoides-borne diseases in Europe.

The difficulties of exporting require immense commitment on the part of owner-managers of SMEs. This article sought to investigate how the commitment of owner-managers to the export market influences the export capacity of SMEs in a developing country context such as South Africa. It found that export commitment influences export capacity indirectly by means of the SME’s export capabilities and confirms the importance of an experiential learning process in the case of SME exporters within developing countries. The article emphasises the importance of the SME owner-manager’s commitment to set upon the often difficult and energy sapping experiential learning process for developing export capacity. Up to now, much of the literature on SME internationalisation from developing countries addresses what factors contribute towards their internationalisation but not how they internationalise. We have integrated three concepts in the internationalisation literature - export commitment, export capability and export capacity - into a process model on how export capacity develops among SMEs.

Veliki američki jetreni metilj Fascioloides magna, predstavlja parazita iz klase Trematoda, koji ima veliki epizootiološki značaj kako za jelene tako i za domaće preživare. Parazit značajno utiče na zdravstveni status jelena, ali što je veoma bitno, jaja parazita jeleni šire na okolinu, te se infestacijom domaćih preživara (goveda, ovce, koze) stvaraju velike ekonomske štete i gubici. Pojava ove parazitoze u Evropi veže se za 19. stoljeće i uvoz invadiranih američkih jelena. Posljednjih decenija F. magna je evidentiran u mnogim evropskim zemljama, a posljednjih godina i u susjednoj Hrvatskoj (Baranja). S obzirom na postojanje populacije evropskog jelena (Cervus elaphus) u Bosni i Hercegovini, upravo uz granicu sa Hrvatskom, odnosno rijeku Savu od Kozare do Semberije, uočena su i sezonska migriranja jelena iz Hrvatske i nazad. Ove prirodne migracije mogu predstavljati veliki problem za epizootiološku situaciju vezanu za pojavu i širenje fascioloidoze u Bosni i Hercegovini. Pojavljivanje navedene bolesti nanijelo bi značajan problem za populacije ugroženih divljih populacija, ali i domaćeg stočarstva. Stoga bi prioritet naše države, ali i susjednih zemalja, trebao biti prekogranični monitoring jelenske divljači, te vršenje inventarizacije parazitofaune jelena, u cilju sprečavanja pojave i širenja fascioloidoze i drugih parazitoza i sprečavanja štete već osiromašenom stočarstvu u našoj zemlji.Ključne riječi: migracija, jeleni, Fascioloides magna, Bosna i Hercegovina

In view of important neurobiological functions of the cell adhesion molecule contactin-6 (Cntn6) that have emerged from studies on null-mutant mice and autism spectrum disorders (ASD) patients, we set out to examine pathways underlying functions of Cntn6 using a proteomics approach. We identified the cell adhesion GPCR latrophilin-1 (Lphn1, a.k.a. CIRL1/CL, ADGRL1) as a binding partner for Cntn6 forming together a heteromeric cis-complex. Lphn1 expression in cultured neurons caused reduction in neurite outgrowth and increase in apoptosis, which was rescued by coexpression of Cntn6. In cultured neurons derived from Cntn6-/- mice, Lphn1 knockdown reduced apoptosis, suggesting that the observed apoptosis was Lphn1-dependent. In line with these data, the number of apoptotic cells was increased in the cortex of Cntn6-/- mice compared to wild-type littermate controls. These results show that Cntn6 can modulate the activity of Lphn1 by direct binding and suggests that Cntn6 may prevent apoptosis thereby impinging on neurodevelopment.

Background: The aim of this study was to evaluate the functional capacity of the liver based on the activity of specific enzymes and bilirubin in serum and also to investigate the influence of mechanical and toxic effects of Fasciola hepatica on the structures of the blood vessels and biliary tract in the sheep liver.Methods: Blood samples and liver of 63 indigenous sheep of Pramenka breed, slaughtered in the period from March to December 2009 were used. Based on parasitological findings in the liver, all animals were divided into two groups: control (n=34) and infected group (n=29). For investigation and description of pathological changes in sheep liver, naturally infected with F. hepatica, corrosion cast technique was used.Results: Biochemical analysis of tested parameters showed a significant elevation (P≤0.05) of serum gamma-glutamyl transferase (GGT), total bilirubin (TBIL) and direct bilirubin (DBIL) in infected sheep group comparing with the control group. No significant differences were observed for activity of aspartate aminotranferase (AST) between groups. Vascular and biliary systems of the liver were found to be affected.Conclusion: Results of biochemical analysis are consistent with pathological findings and measuring of tested parameters could be used in early diagnosis of sheep fasciolosis and to test the effectiveness of anthelmintic therapy. Corrosion cast technique is very useful for investigation of pathological changes and neoangiogenesis of vascular and biliary system in sheep liver, caused by mechanical and toxic effects of F. hepatica.

Research of systems for oxygen enrichment of the water on the fish farms was carried out at the salmon farm, providing information on the practical application of the devices for oxygen enrichment of the water (sprinkler) given the fact the salmon farm in question constantly faces the problem of reduced water inflow and consequent reduced concentration of oxygen (O2) in water. The aforementioned could result in lowered economic profitability of the production as well as serious health problems of fish on the farms. The role of the devices for efficient oxygen enrichment of water within the systems for intensive fish farming is to control and maintain optimal concentration of oxygen as a precondition for quality production, improvement of health and quality of fish, and to allow fish breeding in the fish farms during the drought season, lowered water levels in waterbeds and reduced inflow.

In controlled breeding, parasitic diseases represent one of the major problems of wildlife. Apart from having mechanical, toxic and allergic effects, parasites can transmit other pathogenic microorganisms. Together with poor nutrution, on winter conditions in particular, severe infestations result in worsening of the body condition, sickness and death. The paper presents previous investigations of parasitofauna of wild animals in the area of Bosnia and Herzegovina. Key words: wildlife, parasitofauna, Bosnia and Herzegovina

The aim of this study was to determine the changes in the functional capacity of the liver based on the activity of specific enzymes and bilirubin in serum, and then to explore the possibilities of using them in the early diagnosis and prognosis of sheep fasciolosis and dicrocoeliosis. The study included a total of 56 indigenous sheep of the Pramenka breed of both sexes aging between 1-3 years. Based on the parasitological examination of the liver, the tested animals were divided into three groups: control - healthy and uninfested sheep, the test group A - sheep infested with F. hepatica and the test group B - sheep infested with D. dendriticum. Values of AST, GGT, TBIL and DBIL were measured in the serum of the tested animals, and statistically significant differences (pThe obtained results of biochemical analysis showed significant liver disfunction in fasciolosis, compared with sheep dicrocoeliosis. The degree of these changes and liver disfunction is directly dependent on the intensity of infestation in a way the more parasites the more raised tested serum parameters. Measuring of AST, GGT, TBIL and DBIL in the serum of sheep can be used to prognose the outcome of the disease, while in the diagnosis of sheep fasciolosis and dicrocoeliosis can be used as an additional tool only, particularly in cases of severe and long-lasting infestations as well as suspected disease.
