Abstract	Microvascular surgery, plastic and reconstructive hand surgery, and coronary artery bypass surgery call for a microanatomical study of the branching pattern of the superficial palmar arch (SPA). For the anatomical analysis, we used a group of 20 dissected human hands injected with 4% formaldehyde solution and a 10% mixture of melted gelatin and India ink. The morphometric study was performed on 40 human hands of adult persons injected with methyl-methacrylate fluid into the ulnar and radial arteries simultaneously and afterwards corroded in 40% KOH solution for the preparation of corrosion cast specimens. The mean diameter of the SPA, between the second and third common palmar digital arteries, was 1.86 ± 0.08 mm. We identified the persistent median artery (PMA) in 5% of hands. We distinguished the three main groups of the SPAs according to variations in morphology and branching of the arch: Type 1, the long SPA; Type 2, the middle length SPA; and Type 3, the short SPA found in 27.5% of specimens. The communicating branch (CB), a vessel interconnecting the SPA to the closest branch of the radial artery, is classified into two different morphological groups. The third type of incomplete short arterial arch is the most important of the three groups of SPAs. That short SPA is potentially inadequate for restoring circulation after occlusion or radial artery harvesting for coronary artery bypass.

Abstract	The aim of this study was the micromorphological analysis of the distribution of microvessels, mast cells and ganglionic neurons in two parts, proximal and distal of the human superior cervical sympathetic ganglions (SCSGs). Statistical analyses were applied to detect the possible metric regional differences in their densities. Five injected human SCSGs with colored India ink and gelatin were microdissected and examined. Second group of five human SCSGs was prepared and serially sliced for CD34 and mast cell tryptase immunostaining. The microscopic fields of two parts of the SCSGs were analyzed for the following quantifications: microvessel density (MVD), mast cell density (MCD), and ganglionic cell count and measurements. The mean number of CD34-positive microvessels in microscopic fields, the MVD, had a value of 83 for the upper parts, and 82.7 for the lower parts of SCSGs. The mean number of tryptase-positive mast cells in microscopic fields, the MCD, was 4.5 in the proximal parts, and 4.7 in the distal parts of SCSGs. The mean number of ganglionic neurons in microscopic fields was 19.5 in the proximal parts, and 19.8 in the distal parts of SCSGs. The density of CD34-positive microvessels, the density of tryptase-positive mast cells, and the density, mean diameters and mean areas of ganglionic neurons were not significantly different in two observed parts, upper and lower of the SCSGs. In conclusion, the distributions of microvessels, mast cells, and neurons in two parts of the SCSGs were uniform with no specific micromorphological variations, there is a homogenous vascular and cellular pattern within the SCSGs.

Abstract	Background: Peripheral facial nerve palsy is a relatively frequent, rather idiopathic, and isolated nonprogressive disorder with a tendency toward spontaneous recovery in children. It is primarily characterized by unilateral paresis or paralysis of the mimic musculature affecting verbal communication, social interactions, and quality of life. Objective: This study aimed to evaluate the clinical aspects and efficacy of different therapeutic modalities in the population of children and adolescents with acute peripheral facial nerve palsy, the quality and recovery rate in comparison to different therapy modalities and etiological factors as well as to determine parameters of recovery according to the age of patients. Methods: The retrospective study included children and adolescents (n=129) with an acute onset of peripheral facial nerve palsy, diagnosed and treated in the Clinic of Neurology and Psychiatry for Children and Youth in Belgrade (2000-2018). The mean age of the patients was 11.53 years (SD±4.41). Gender distribution: 56.6% female and 43.4% male patients. Results: There were 118 (91.5%) patients with partial and 11 (8.5%) patients with complete paralysis. Left-sided palsy occurred in 67 (51.9%) patients, right-sided in 58 (45.0%), while there were 4 (3.1%) bilateral paralyses. The most common etiological factor was idiopathic (Bell's palsy) - 74 (57.4%) patients followed by middle ear infections - 16 (12.4%). Regardless of etiology, age, and therapy protocols, there was a significant recovery in most of the patients (p<0.001), without significant differences in recovery rate. Comparison of inpatient and outpatient populations showed significant differences regarding the number of relapses, severity of clinical presentation, and recovery rate in relation to etiology. Conclusion: Bell's palsy is shown to be the most common cause of peripheral facial nerve palsy in children and adolescents, regardless of gender. It is followed by mid-ear infections, respiratory infections, and exposure to cold. Most children and adolescents recovered in three weeks after initial presentation, regardless of etiology, age, and therapy.

Abstract	Silver nanoparticles have numerous potential applications in engineering, industry, biology and medicine. Because of their unique chemical properties, they have become the focus of many research teams all over the world. Silver nanoparticles may exhibit significant antimicrobial and anticancer effects, and they may be a valuable part of various bioassays and biosensors. However, the research on biological and medical uses of AgNPs is related with numerous potential problems and challenges that need to be overcome in the years ahead. Possible toxic effects of silver nanoparticles on living organisms represent a great concern, both in clinical medicine and public health. Nevertheless, in the future, it may be expected that all metallic nanomaterials, including the ones made from silver will greatly benefit almost all natural scientific fields. In this short review, we focus on the recent research on silver nanoparticles in experimental physiology, as well as other areas of fundamental and clinical medicine.

Abstract	The aim of this study was to quantify the distribution of microvessels and mast cells in all three parts of the trigeminal ganglion (TG). Statistical analyses were applied to investigate possible micromorphological regional differences in their density. Five serially sectioned human TGs were prepared for CD34 and mast cell tryptase immunostaining. The following quantifications were performed in microscopic fields of three parts of the TG: microvessel density (MVD), mast cell density (MCD) and ganglionic cell count. The density of CD34-positive microvessels was not significantly different in any of the three observed parts of the TG. The distribution of neurons showed no significant statistical difference in three parts of the TG. There was no difference in the density of tryptase-positive mast cells within the TG, but there was an abundant presence of mast cells in the periganglionic dural and subdural tissues, a finding hitherto not reported. We can say that there is a homogenous vascular pattern within the TG which excludes local predominance in pathogenesis of trigeminal neuralgia. Second, and more important, the finding of peri-trigeminal mast cells indicates their important role in migraine pain and confirms their degranulation as the main therapeutic goal for this condition.

Abstract	Background/Aim. The optic nerve is anatomically observed in four segments: intrabulbar, orbital, canalicular, and cranial. According to the literature, the surface of the transversal cut of the nerve is different through it. The aim of this study was to evaluate the fascicular organisation of the optic nerve, throughout its three segments from the eye. Methods. Five pairs of optic nerves, obtained from the autopsies were examined. Using Heidenhain's (azan) staining, the cuts were prepared for microscopy. Morphometric analysis was performed using the stereological methods for morphometric cytology - the Weible’s testing system M42. The following measures were established: the surface of the transverse cut of the nerve, the entire surface of fasciculi, the entire surface of connective tissue and blood vessels, the number of fasciculi, the surface of a single fasciculus. Results. The surface of the transverse cut of the nerve was found to grow from the orbital to the cranial segment, as well as the entire surface of fasciculi. While their number is significantly lower in the cranial segment, the number of fasciculi varied slightly between the orbital and the canalicular segment. The surface of a single fasciculus grows from the bulb to the chiasma. There is probable a cause to believe that this may be due to fusion of the “small” fasciculi in the orbitocranial direction. Conclusion. There are significant differences among the examined parameters of the different parts of the optic nerve.

Abstract	In this study, the in vivo hypoglycemic effect of a donut-shaped polyanion salt (NH₄)₁₄[Na@P₅W₃₀O₁₁₀]·31H₂O {NaP₅W₃₀} and its Ag-containing derivative K₁₄[Ag@P₅W₃₀O₁₁₀]·22H₂O·6KCl {AgP₅W₃₀}, as well as their hepatotoxicity and nephrotoxicity, was evaluated. In the screening hypoglycemic study, Wistar albino rats with streptozotocin induced diabetes were treated intraperitoneally with three single doses (5, 10, and 20 mg per kg per b.w.) of both investigated polyoxotungstates. The blood glucose levels, measured before and after 2, 4 and 6 h polyoxotungstate application, showed that both studied compounds induced the most pronounced and time dependent glucose lowering effects at the doses of 20 mg kg⁻¹. Thus, daily doses of 20 mg kg⁻¹ were administered to Wistar albino rats orally for 14 days in further toxicity examinations. The serum glucose concentration and biochemical parameters of kidney and liver function, as well as a histopathological analysis of kidney and liver tissues were evaluated 14 days after the polyoxotungstate administration. Both investigated compounds did not induce statistically significant alterations of the serum glucose and uric acid concentrations, as well as some of the liver function markers (serum alanine and aspartate aminotransferases, and alkaline phosphatase activities). However, the significant decrease in serum total protein and albumin concentrations and the increase in biochemical parameters of renal function – serum urea (up to 63.1%) and creatinine concentrations (up to 23.3%) were observed for both polyoxotungstates. In addition, the detected biochemical changes were in accordance with kidney and liver histhopathological analysis. Accordingly, the hepatotoxic and nephrotoxic effects of these potential antidiabetic polyoxotungstates could be considered as mild.
