Abstract	Co-digestion implementation in wastewater treatment plants enhances biogas yield, so this research investigated the optimal ratio of biodegradable waste and sewage sludge. The increase in biogas production was investigated through batch tests using basic BMP equipment, while synergistic effects were evaluated by chemical oxygen demand (COD) balance. Analyses were performed in four volume basis ratios (3/1, 1/1, 1/3, 1/0) of primary sludge and food waste with added low food waste: 3.375%, 4.675%, and 5.35%, respectively. The best proportion was found to be 1/3 with the maximum biogas production (618.7 mL/g VS added) and the organic removal of 52.8% COD elimination. The highest enhancement rate was observed among co-digs 3/1 and 1/1 (105.72 mL/g VS). A positive correlation between biogas yield and COD removal is noticed while microbial flux required an optimal pH, value of 8 significantly decreased daily production rate. COD reductions further supported the synergistic impact; specifically, an additional 7.1%, 12.8%, and 17% of COD were converted into biogas during the co-digestions 1, 2, and 3, respectively. Three mathematical models were applied to estimate the kinetic parameters and check the accuracy of the experiment. The first-order model with a hydrolysis rate of 0.23-0.27 indicated rapidly biodegradable co-/substrates, modified Gompertz confirmed immediate commencement of co-digs through zero lag phase, while the Cone model had the best fit of over 99% for all trials. Finally, the study points out that the COD method based on linear dependence can be used for developing relatively accurate model for biogas potential estimation in anaerobic digestors.

Abstract	Objective: Risk factors for epilepsy in meningioma patients are not yet clearly defined, however, seizure freedom is a significant factor for quality of life after surgery. Methods: We performed a retrospective study of the 333 adult patients who received surgery for supratentorial meningioma at our center. Various clinical, radiological, and surgical variables were included in the multivariate regression, and the outcomes measured were the occurrence of seizure(s) preoperatively, during the hospitalization, and during the follow-up period. Results: A total of 89 (26.7%) patients experienced preoperative seizures, of whom 62.9% were seizure free after the surgery. Of 244 patients without epilepsy before surgery, 11.9% had at least one seizure postoperatively. In total, 63 of our patients (18.9%) experienced seizures after the surgery, of whom 20 had refractory epilepsy. Multivariate analysis identified the following predictors of preoperative seizures: the absence of headache (OR: 0.23, CI: 2.55-8.50), the presence of significant peritumoral edema (OR: 4.35, CI: 2.57-7.35), and younger age (OR: 0.97 per year increase, CI: 0.95-0.99). Factors associated with early postoperative seizures were: younger age (OR: 0.96 per year increase, CI: 0.93-0.99) and the presence of preoperative seizures (OR: 2.73, CI: 1.13-6.57), while the presence of preoperative seizures (OR: 4.73, CI: 2.05-10.92), tumor progression (OR: 5.38, CI: 2.25-12.89), and neurological worsening (OR: 5.21 CI: 1.72-15.81) were significant for late postoperative seizures. Significance: Our results from a single-center meningioma cohort confirm, in general, data from some previous studies regarding patients' characteristics for both preoperative and overall postoperative epilepsy. Besides previously described risk factors, younger age was important for preoperative and early postoperative seizures. Epilepsy is common in patients with recurrence of meningioma, but the variables of significance for refractory seizures in these patients require further examination.

Abstract	Every third patient with intracranial meningioma develops seizures of poorly understood etiology. Tumor and peritumoral edema may exert mechanical pressure on the cortex that may affect mechano-gated potassium channels - KCNK2 and KCNK4. These channels regulate neuron excitability and have been related to seizures in some other conditions. The objective of the present study was to explore a potential relation between the levels of these proteins in tumor tissue and adjacent cortex and seizures development. The study included 19 meningioma patients that presented one or more preoperative seizures and 24 patients with no seizures. Tissue samples were collected in the course of surgical removal of the meningioma. Postoperative seizure freedom was achieved in 11 out of 19 patients. The relative level of KCNK2 in the cortical tissue was lower in patients with preoperative seizures. On the other hand, cortical tissue level of KCNK4 was higher in patients that became seizure-free after the surgery. In addition, relative levels of KCNK4 in the cortical and tumor tissue appear to be lowered by the treatment with anti-seizure medication levetiracetam. These results imply that KCNK2 and KCNK4 may be involved in the development of meningioma-related seizures and may represent promising therapeutic targets.

Abstract	Coronavirus disease (COVID-19) in immunocompromised patients represents a major challenge for diagnostics, surveillance, and treatment. Some individuals remain SARS-CoV-2 PCR-positive for a prolonged period. The clinical and epidemiological significance of this phenomenon is not well understood. We report a case of a patient with a history of systemic lupus erythematosus (SLE) who has been persistently SARS-CoV-2 PCR positive for 9 months, with multiple thromboembolic complications, and development of nocardial brain abscess successfully treated with surgery and antibiotics.

Abstract	Ixodid ticks are distributed across all countries of the Western Balkans, with a high diversity of species. Many of these species serve as vectors of pathogens of veterinary and medical importance. Given the scattered data from Western Balkan countries, we have conducted a comprehensive review of available literature, including some historical data, with the aim to compile information about all recorded tick species and associated zoonotic pathogens in this region. Based on the collected data, the tick fauna of the Western Balkans encompasses 32 tick species belonging to five genera: Ixodes, Haemaphysalis, Dermacentor, Rhipicephalus and Hyalomma. A range of pathogens responsible for human diseases has also been documented, including viruses, bacteria and parasites. In this review, we emphasize the necessity for integrated surveillance and reporting, urging authorities to foster research by providing financial support. Additionally, international and interdisciplinary collaborations should be encouraged that include the exchange of expertise, experiences and resources. The present collaborative effort can effectively address gaps in our knowledge of ticks and tick-borne diseases.

Abstract	Goldâpolyaniline (AuâPANI) nanocomposite was prepared using a simple interfacial polymerization method, performed in an immiscible water/toluene biphasic system using tetrachloroaurate, AuClââ as an oxidant. The formation of Au nanoparticles (AuNPs) or AuâPANI nanocomposite can be controlled to a certain degree by varying the ratio of initial Auâº and aniline concentrations. Under optimal condition (HAuClâ/aniline ratio is 1:2), green dispersion of AuâPANI nanocomposite is produced in aqueous phase, whose morphology, structure and physicochemical properties are investigated in details. The nanocomposite shows granular morphology with mostly rodlike AuNPs embedded in polymer. It was found that polyaniline in the composite is in the conducting emeraldine salt form, containing high amount of Au (28.85 wt %). Furthermore, the electrical conductivity of the nanocomposite was found to be four-fold higher than that of the polymer itself. In addition, the nanocomposite powder, isolated from the as-prepared aqueous dispersion, can later be easily redispersed in water and further used for various applications. Moreover, the obtained Au-PANI nanocomposite showed excellent electrocatalytic performance toward the electrochemical oxygen reduction reaction (ORR), with high ORR onset potential and good selectivity. This makes it a promising candidate for a new class of Pt-free ORR catalyst.

Abstract	This study explores different mechanisms of antimicrobial action by designing hybrid nanomaterials that provide a new approach in the fight against resistant microbes. Here, we present a cheap copperâpolyaniline (CuâPANI) nanocomposite material with enhanced antimicrobial properties, prepared by simple in situ polymerization method, when polymer and metal nanoparticles are produced simultaneously. The copper nanoparticles (CuNPs) are uniformly dispersed in the polymer and have a narrow size distribution (dâáµ¥ = 6 nm). We found that CuNPs and PANI act synergistically against three strains, Escherichia coli, Staphylococcus aureus, and Candida albicans, and resulting nanocomposite exhibits higher antimicrobial activity than any component acting alone. Before using the colony counting method to quantify its time and concentration antimicrobial activity, different techniques (UVâvisible spectroscopy, transmission electron microscopy, scanning electron microscope, field emission scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectrophotometry, and inductively coupled plasma optical emission spectrometry) were used to identify the optical, structural, and chemical aspects of the formed CuâPANI nanocomposite. The antimicrobial activity of this nanocomposite shows that the microbial growth has been fully inhibited; moreover, some of the tested microbes were killed. Atomic force microscopy revealed dramatic changes in morphology of tested cells due to disruption of their cell wall integrity after incubation with CuâPANI nanocomposite.

Abstract	Introduction: Surgery of tumors localized in the motor cortex is challenging because of the accompanying risk of de novo occurrence of motor deficits. Material and Methods: We report a series of 34 patients with slow-growing brain tumors localized in and around the motor areas of the brain, which were treated at the Institute of Neurosurgery, Clinical Center in Belgrade, from 2008 to 2012. Results: The average distance of the central sulcus in relation to the coronary suture verified ES is 18.38 ± 9.564 mm, and the strength of the current required to obtain motor responses was 9.26 ± 1.286 mA. If the distance from the coronary suture is higher, the current intensity required to cause the motor response is lower ( p < 0.01). The smaller amount of current is needed to identify the motor areas of tumors where the degree of surgical resection was subtotal to the level of reduction compared with radical surgery ( p < 0.05). Conclusion: Direct electrostimulation of the cortex is a reliable method for identification of motor areas of the brain, and it is necessary for additional prevention of iatrogenic neurological deficits. Keywords: motor cortex; anatomical orientation; electrical stimulation
