Abstract
In recent years, especially since the COVID-19 pandemic, the number of predatory journals has increased significantly. Predatory journals exploit the "open-access model" by engaging in deceptive practices such as charging high publication fees without providing the expected quality and performing insufficient or no peer review. Such behaviors undermine the integrity of scientific research and can result in researchers having trouble identifying reputable publication opportunities, particularly early-career researchers who struggle to understand and establish the correct criteria for publication in reputable journals. Publishing in journals that do not fully cover the criteria for scientific publication is also an ethical issue. This review aimed to describe the characteristics of predatory journals, differentiate between reliable and predatory journals, investigate the reasons that lead researchers to publish in predatory journals, evaluate the negative impact of predatory publications on the scientific community, and explore future perspectives. The authors also provide some considerations for researchers (particularly early-career researchers) when selecting journals for publication, explaining the role of metrics, databases, and artificial intelligence in manuscript preparation, with a specific focus on and relevance to publication in veterinary medicine.

Abstract
OBJECTIVES As an important public health concern, antimicrobial resistance (AMR) is related to lack of knowledge among healthcare professionals. Since the Global Action Plan on AMR highlights the importance of training all healthcare professionals, it is essential to focus our attention on the education related to judicious antimicrobial use. The current study was the first attempt in southeastern Europe to quantify the knowledge about antimicrobial usage and biosecurity measure among veterinary students. METHODS This questionnaire-based study was performed between April and May of 2019 on 213 veterinary students of the University of Novi Sad, Serbia and the University of Zagreb, Croatia. RESULTS Veterinary students appeared to be little aware of antimicrobial use in veterinary medicine contribution to overall AMR since only 56.8% have chosen strong contribution as the answer. Of the students surveyed, only 22.1%/35.7% of them strongly agreed/agreed that the amount of teaching time for pharmacology was about right. Students who denied having good knowledge of the pharmacology of antimicrobials showed higher knowledge about systemic use of antimicrobials in different clinical scenarios (p = 0.002). High importance of some antimicrobials for human medicine was not recognized by surveyed students. Only 8.5% of them identified gentamicin correctly, as first-line therapy. Students expected to graduate later were more likely to identify the importance of rating antimicrobials correctly than those who thought they would graduate earlier (p = 0.002). More than half of students gave correct answer at scenario regarding a dog with recurrent pyoderma by choosing culture and susceptibility (C & S) testing. Our students who think they will graduate sooner have higher knowledge level on C & S testing sample submission for range of clinical scenarios (p = 0.004). Moreover, appropriate use of PPE (personal protective equipment) procedure and biosecurity measure were reported for two thirds of our students in case of only for two clinical scenarios. CONCLUSION This study reveals that among veterinary students from Croatia and Serbia improved undergraduate education is needed on the AMR with emphasis on antimicrobial stewardship (AMS) and appropriate biosecurity.

Abstract
This paper addresses the measurement facilities for pre-selection of waste materials prior to measurement for repository acceptance or possible free release (segregation measurement system); and free release (free release measurement system), based on a single standardized concept characterized by unique, patented lead-free shielding. The key objective is to improve the throughput, accuracy, reliability, modularity and mobility of segregation and free-release measurement. This will result in a more reliable decision-making with regard to the safe release and disposal of radioactive wastes into the environment and, resulting in positive economic outcomes. The research was carried out within "Metrology for Decommissioning Nuclear Facilities" (MetroDecom) project.

Abstract
AIM To counteract/reveal celecoxib-induced toxicity and NO system involvement.
METHODS Celecoxib (1 g/kg b.w. ip) was combined with therapy with stable gastric pentadecapeptide BPC 157 (known to inhibit these lesions, 10 μg/kg, 10 ng/kg, or 1 ng/kg ip) and L-arginine (100 mg/kg ip), as well as NOS blockade [N(G)-nitro-L-arginine methyl ester (L-NAME)] (5 mg/kg ip) given alone and/or combined immediately after celecoxib. Gastrointestinal, liver, and brain lesions and liver enzyme serum values in rats were assessed at 24 h and 48 h thereafter.
RESULTS This high-dose celecoxib administration, as a result of NO system dysfunction, led to gastric, liver, and brain lesions and increased liver enzyme serum values. The L-NAME-induced aggravation of the lesions was notable for gastric lesions, while in liver and brain lesions the beneficial effect of L-arginine was blunted. L-arginine counteracted gastric, liver and brain lesions. These findings support the NO system mechanism(s), both NO system agonization (L-arginine) and NO system antagonization (L-NAME), that on the whole are behind all of these COX phenomena. An even more complete antagonization was identified with BPC 157 (at both 24 h and 48 h). A beneficial effect was evident on all the increasingly negative effects of celecoxib and L-NAME application and in all the BPC 157 groups (L-arginine + BPC 157; L-NAME + BPC 157; L-NAME + L-arginine + BPC 157). Thus, these findings demonstrated that BPC 157 may equally counteract both COX-2 inhibition (counteracting the noxious effects of celecoxib on all lesions) and additional NOS blockade (equally counteracting the noxious effects of celecoxib + L-NAME).
CONCLUSION BPC 157 and L-arginine alleviate gastrointestinal, liver and brain lesions, redressing NSAIDs’ post-surgery application and NO system involvement.

Abstract
A new large-volume metal reference standard has been developed. The intended use is for calibration of free-release radioactivity measurement systems and is made up of cast iron tubes placed inside a box of the size of a Euro-pallet (80 × 120 cm). The tubes contain certified activity concentrations of (60)Co (0.290 ± 0.006 Bq g(-1)) and (110m)Ag (3.05 ± 0.09 Bq g(-1)) (reference date: 30 September 2013). They were produced using centrifugal casting from a smelt into which (60)Co was first added and then one piece of neutron irradiated silver wire was progressively diluted. The iron castings were machined to the desirable dimensions. The final material consists of 12 iron tubes of 20 cm outer diameter, 17.6 cm inner diameter, 40 cm length/height and 245.9 kg total mass. This paper describes the reference standard and the process of determining the reference activity values.

Abstract
AIM We hypothesized that certain effects of the general anaesthetic thiopental are dependent on NO-related mechanisms, which were consequently counteracted by stable gastric pentadecapeptide BPC 157. MAIN METHODS (1) All rats intraperitoneally received thiopental (20, 30, 40, and 50 mg/kg) while medication BPC 157 (10 μg/kg, 10 ng/kg, and 10 pg/kg) was given intraperitoneally at 5 min before thiopental. (2) To determine NO-related mechanisms, all rats received intraperitoneally thiopental 40 mg/kg while BPC 157 (10 μg/kg), L-NAME (10 mg/kg) and L-arginine (30 mg/kg) were applied alone and/or combined. BPC 157 was given at 25 min before thiopental while L-NAME, L-arginine, alone and/or combined, were applied at 20 min before thiopental. KEY FINDINGS (1) BPC 157 own effect on thiopental anaesthesia: BPC 157 (10 ng/kg and 10 μg/kg) caused a significant antagonism of general anaesthesia produced by thiopental with a parallel shift of the dose-response curve to the right. (2) L-NAME-L-arginine-BPC 157 interrelations: L-NAME: Thiopental-induced anaesthesia duration was tripled. L-arginine: Usual thiopental anaesthesia time was not influenced. Active only when given with L-NAME or BPC 157: potentiating effects of L-NAME were lessened, not abolished; shortening effect of BPC 157: abolished. BPC 157 and L-NAME: Potentiating effects of L-NAME were abolished. BPC 157 and L-NAME and L-arginine: BPC 157 +L-NAME +L-arginine rats exhibited values close to those in BPC 157 rats. SIGNIFICANCE Thiopental general anaesthesia is simultaneously manipulated in both ways with NO system activity modulation, L-NAME (prolongation) and BPC 157 (shortening/counteraction) and L-arginine (interference with L-NAME and BPC 157).

Abstract
While very rarely reported, duodenocutanenous fistula research might alter the duodenal ulcer disease background and therapy. Our research focused on rat duodenocutaneous fistulas, therapy, stable gastric pentadecapeptide BPC 157, an anti-ulcer peptide that healed other fistulas, nitric oxide synthase-substrate L-arginine, and nitric oxide synthase-inhibitor L-nitro-arginine methyl ester (L-NAME). The hypothesis was, duodenal ulcer-healing, like the skin ulcer, using the successful BPC 157, with nitric oxide-system involvement, the "wound healing-therapy", to heal the duodenal ulcer, the fistula-model that recently highlighted gastric and skin ulcer healing. Pressure in the lower esophageal and pyloric sphincters was simultaneously assessed. Duodenocutaneous fistula-rats received BPC 157 (10 μg/kg or 10 ng/kg, intraperitoneally or perorally (in drinking water)), L-NAME (5 mg/kg intraperitoneally), L-arginine (100 mg/kg intraperitoneally) alone and/or together, throughout 21 days. Duodenocutaneous fistula-rats maintained persistent defects, continuous fistula leakage, sphincter failure, mortality rate at 40% until the 4(th) day, all fully counteracted in all BPC 157-rats. The BPC 157-rats experienced rapidly improved complete presentation (maximal volume instilled already at 7(th) day). L-NAME further aggravated the duodenocutaneous fistula-course (mortality at 70% until the 4(th) day); L-arginine was beneficial (no mortality; however, maximal volume instilled not before 21(st) day). L-NAME-worsening was counteracted to the control level with the L-arginine effect, and vice versa, while BPC 157 annulled the L-NAME effects (L-NAME + L-arginine; L-NAME + BPC 157; L-NAME + L-arginine + BPC 157 brought below the level of the control). It is likely that duodenocutaneous fistulas, duodenal/skin defect simultaneous healing, reinstated sphincter function, are a new nitric oxide-system related phenomenon. In conclusion, resolving the duodenocutanenous fistulashealing, nitric oxide-system involvement, should illustrate further wound healing therapy to heal duodenal ulcers.

Abstract
BACKGROUND BPC 157 is a stable gastric pentadecapeptide recently implicated with a role in hemostasis. While NO is largely implicated in hemostatic mechanisms, in tail-amputation-models under heparin- and warfarin-administration, both the NO-synthase (NOS)-blocker, L-NAME (prothrombotic) and the NOS-substrate L-arginine (antithrombotic), were little investigated. Objective. To investigate the effect of L-NAME and L-arginine on hemostatic parameters, and to reveal the effects of BPC 157 on the L-NAME- and L-arginine-induced hemostatic actions under different pathological condition: tail amputation without or with anticoagulants, heparin or warfarin. METHODS Tail amputation, and/or i.v.-heparin (10 mg/kg), i.g.-warfarin (1.5 mg/kg/day for 3 days) were used in rats. Treatment includes BPC 157, L-NAME, L-arginine, per se and their combination. RESULTS After (tail) amputation, with or without i.v.-heparin or i.g.-warfarin, BPC 157 (10 μg/kg, 10 ng/kg, i.p., i.v. (heparin), 10 μg/kg i.g. (warfarin)) always reduced bleeding time and/or haemorrhage and counteracted thrombocytopenia. As for L-NAME and/or L-arginine, we noted: L-arginine (100 mg/kg i.p.)-rats: more bleeding, less/no thrombocytopenia; L-NAME (5 mg/kg i.p.)-rats: less bleeding (amputation only), but present thrombocytopenia; L-NAME+L-arginine-rats also exhibited thrombocytopenia: L-NAME counteracted L-arginine-increased bleeding, L-arginine did not counteract L-NAME-thrombocytopenia. All animals receiving BPC 157 in addition (BPC 157 μg+L-NAME; BPC 157 μg+L-arginine, BPC 157 μg+L-NAME+L-arginine), exhibited decreased haemorrhage and markedly counteracted thrombocytopenia. CONCLUSIONS L-NAME (thrombocytopenia), L-arginine (increased haemorrhage) counteraction and BPC 157 (decreased haemorrhage, counteracted thrombocytopenia) with rescue against two different anticoagulants, implicate a BPC 157 modulatory and balancing role with rescued NO-hemostatic mechanisms.

Abstract
We reviewed stable gastric pentadecapeptide BPC 157-NO-system-relation, its close participation in Moncada's (maintained vascular integrity, platelets control) homeostatic healing response of NO-system to injury. Namely, BPC 157's particular healing effect also affects all events after vascular integrity loss (dependent on circumstances, it reduces either thrombosis (abdominal aorta anastomosis) or bleeding/thrombocytopenia (amputation, heparin, warfarin, aspirin)) and in a series of different injurious models, acute and chronic, BPC 157 consistently advances healing after severe injuries in various tissues spontaneously unable to heal; stimulates egr-1 and naB2 genes; exhibits high safety (LD1 not achieved)). Hypothesis, that BPC 157 (since formed constitutively in the gastric mucosa, stable in human gastric juice, along with significance of NO-synthase and the basal formation of NO in stomach mucosa, greater than that seen in other tissues) exhibits a general, effective competing both with L-arginine analogues (i. e., L-NAME) and L-arginine, and that this has some physiologic importance (NO-generation), later, practically supports its beneficial effects illustrating BPC 157 and NOsystem mutual (with L-NAME/L-arginine; alone and together) relations in (i) gastric mucosa and mucosal protection, following alcohol lesions, in cytoprotection course, NO-generation, and blood pressure regulation; (ii) alcohol acute/chronic intoxication, and withdrawal; (iii) cardiovascular disturbances, chronic heart failure, pulmonary hypertension, and arrhythmias; (iv) disturbances after hypokalemia and hyperkalemia, and potassium-cell membrane dysfunction; and finally, in (v) complex healing failure, proved by the fistulas healing, colocutaneous and esophagocutaneous. However, how this advantage of modulating NO-system (i. e., particular effect on eNOS gene), may be practically translated into an enhanced clinical performance remains to be determined.

Abstract
Stable gastric pentadecapeptide BPC 157 was suggested to link inflammatory bowel disease and multiple sclerosis, and thereby, shown to equally counteract the models of both of those diseases. For colitis, cysteamine (400 mg/kg intrarectally (1 ml/rat)) and colon-colon anastomosis (sacrifice at day 3, 5, 7, and 14) were used. BPC 157 (10 μg/kg, 10 ng/kg) was applied either intraperitoneally once time daily (first application immediately after surgery, last at 24 hours before sacrifice) or per-orally in drinking water (0.16 μg/ml/12 ml/day till the sacrifice) while controls simultaneously received an equivolume of saline (5 ml/kg) intraperitoneally or drinking water only (12 ml/day). A multiple sclerosis suited toxic rat model, cuprizone (compared with standard, a several times higher regimen, 2.5% of diet regimen + 1 g/kg intragastrically/day) was combined with BPC 157 (in drinking water 0.16 μg or 0.16 ng/ml/12 ml/day/rat + 10 μg or 10 ng/kg intragastrically/day) till the sacrifice at day 4. In general, the controls could not heal cysteamine colitis and colon-colon anastomosis. BPC 157 induced an efficient healing of both at the same time. Likewise, cuprizone-controls clearly exhibited an exaggerated and accelerated damaging process; nerve damage appeared in various brain areas, with most prominent damage in corpus callosum, laterodorsal thalamus, nucleus reunions, anterior horn motor neurons. BPC 157-cuprizone rats had consistently less nerve damage in all damaged areas, especially in those areas that otherwise were most affected. Consistently, BPC 157 counteracted cerebellar ataxia and impaired forelimb function. Thereby, this experimental evidence advocates BPC 157 in both inflammatory bowel disease and multiple sclerosis therapy.

Abstract
Stable gastric pentadecapeptide BPC 157 is an anti-ulcer peptidergic agent, proven in clinical trials to be both safe in inflammatory bowel disease (PL-10, PLD-116, PL 14736) and wound healing, stable in human gastric juice, with no toxicity being reported. Recently, we claim that BPC 157 may be used as an antidote against NSAIDs. We focused on BPC 157 beneficial effects on stomach, duodenum, intestine, liver and brain injuries, adjuvant arthritis, pain, hyper/hypothermia, obstructive thrombus formation and thrombolysis, blood vessel function, counteraction of prolonged bleeding and thrombocytopenia after application of various anticoagulants and antiplatelet agents and wound healing improvement. The arguments for BPC 157 antidote activity (i.e., the role of BPC 157 in cytoprotection, being a novel mediator of Robert's cytoprotection and BPC 157 beneficial effects on NSAIDs mediated lesions in the gastrointestinal tract, liver and brain and finally, counteraction of aspirin-induced prolonged bleeding and thrombocytopenia) obviously have a counteracting effect on several established side-effects of NSAIDs use. The mentioned variety of the beneficial effects portrayed by BPC 157 may well be a foundation for establishing BPC 157 as a NSAIDs antidote since no other single agent has portrayed a similar array of effects. Unlike NSAIDs, a very high safety (no reported toxicity (LD1 could be not achieved)) profile is reported for BPC 157. Also, unlike the different dosage levels of aspirin, as a NSAIDs prototype, which differ by a factor of about ten, all these beneficial and counteracting effects of BPC 157 were obtained using the equipotent dosage (μg, ng/kg) in parenteral or peroral regimens.

Abstract
Concentrations of lindane from adipose tissue i.e. omentum of sheep from homesteads of island Krk that were treated with lindane, were compared with the concentrations of lindane measured in adipose tissue of non treated sheep from husbandry cooperative on island Cres. Evaluation of food safety for this samples were estimated by comparing obtained results and maximum tolerance concentration (MTC) for lindane (2.0 and 0.2 mg/kg). In treated lambs from Krk measured concentrations of lindane were in range from 0.0038 to 1.8644 mg/kg, and in treated sheep from 0.0094 to 1.646 mg/kg. In control group of lambs and sheep concentration of lindane was < or = 0.0051 mg/kg. Estimation of food safety based on the results from this research are discussable, regarding the fact that MTC prescribed before year 2007 was 2.0 mg/kg. When the new law Regulations of MTC for residues of pesticides in food and animal feed (NN 119/07) came into the force prescribed MTC was 0.02 mg/kg. If food safety of sheep meat from Krk would be estimated based on latter, then 73.4% of samples of lamb meat and 80% of sheep meat could be proclaimed unsafe for human consumption. It is encouraging that after completion of using lindane in year 2005, levels of lindane in adipose tissue of lamb from Krk in year 2006 were under the concentration set by new legislate (< 0.02 mg/kg).

Abstract
Magnetic resonance imaging is used commonly to diagnose intervertebral disk herniation in dogs. It is common to locate areas of suspected compression on sagittal T2-weighted (T2-W) images and then obtain limited transverse images in these areas to reduce the acquisition time (a step-by-step approach). Our objective was to assess the frequency of correct localization of spinal cord compression due to disk herniation using only the sagittal images. The results from isolated readings of the sagittal T2-W images alone or combined with a single-shot fast spin echo (SSFSE) slab in 118 dogs were compared with a gold standard, based on a consensual reading of all images available, including complete transverse images across the entire spinal segments under study. The sites of compression were localized correctly from the sagittal images in 89.8% of dogs. If only the most significant lesions were accounted for, the percentage increased up to 95.2%. In 54.9% of the readings with incorrect localization, the actual compressive site was immediately adjacent to the one suspected from review of the sagittal images. The frequency of correct localization was higher in the cervical region, and was increased by examination of the SSFSE slab. The most common cause of disagreement was the presence of multiple degenerate bulging disks. Based on these results we recommend obtaining transverse images across the entire segment when multiple bulging disks are present. It is also recommended to obtain transverse images across the spaces immediately adjacent to the suspected site of herniation from review of the sagittal images.
