Assessment of the physiological and immunological status of fish is an urgent problem of modern aquaculture. One of the methods of such assessment is based on hematological and biochemical studies. Blood is the most sensitive and informative indicator of changes occurring in the body of fish. It reacts quickly and acutely to the effects of various adverse environmental factors and can serve as one of the early indicators of a violation of the functional state of fish. The study
of the effect of a probiotic drug on the enterosorbent “Florin forte” on hematological and biochemical blood parameters, in particular, on the level of hemoglobin, total serum protein, triglycerides, cholesterol, glucose, as well as on the distribution of shaped elements of peripheral blood of Bester (Huso huso × Acipenser ruthenus) was carried out on the basis of the Innovation Center “Bioaquapark – scientific andtechnical center of aquaculture” ASTU for 30 days. As a result of the conducted studies, it was noted that the use of the sorbed form of the probiotic drug has a positive effect on the physiological and immunological condition of the farmed fish. Thus, the blood of Bester's two-year-olds grown on compound feeds with the addition of probiotic enterosorbent was characterized by an increase in hemoglobin levels to 64.9 g/l, total whey protein to 23.6 g/l, as well as a decrease in cholesterol and glucose concentrations to 2.6 and 0.55 mmol/l, respectively. In the leukocyte formula of the studied fish, shifts in the quantitative ratios of leukocytes were found, confirming the body's reaction to the introduction of a probiotic drug on enterosorbent into the diet and considered as an adaptive mechanism that increases the protective function of the blood.

Published: December 2023

During the wintering period, sander from their natural habitat and grown in farm conditions undergo changes in morphophysiological and chemical status due to the expenditure of energy reserves of the body and the redistri-bution of nutrients in the muscles and liver. This is expressed in a significant decrease in the content of ab-dominal fat in the body of wild and factory individuals (by 45 and 16%, respectively), muscle fat content (by 26% in wild individuals) and liver (by 59% in wild and 16% in farm fish), vitamin C in muscles (by 56 and 23%, respectively). At the same time, the content of nitrogen–free extractives in the muscles and liver increases many times – by 47 and 31%, respectively, in wild individuals and by 31 and 29% in sander raised in cages. The proportion of monounsaturated fatty acids in the lipids of sander muscles in winter significantly increases and the proportion of polyunsaturated fatty acids (PUFA) decreases, especially eicosapentaenoic (EPA), docosahexaenoic (DHA) and arachidonic, against the background of an increase in the level of these acids in the liver. From the point of view of meat quality, estimated by the content of long-chain PUFA, during the wintering period there is a significant decrease in the nutritional value
of caught and raised fish, which is expressed in a 2-3-fold decrease in EPA + DHA in fillets. Such changes are the adaptation of fish to cold temperature conditions during prolonged wintering and are associated with puberty.

Abstract
Astaxanthin (ASTA) and zeaxanthin (ZEA) are xanthophyll carotenoids showing a wide spectrum of health-promoting properties. However, their utilization is limited, mostly due to poor water solubility, limited bioavailability, and a tendency to oxidate, as well as photo- and thermal instability. The aim of this work was to develop ASTA- and ZEA-loaded nano-structured lipid carriers (NLCs) that would protect them against degradation and improve their intestinal stability/permeability. Obtained NLCs were characterized by an effective diameter of 294 nm for ASTA-NLC and 280 nm for ZEA-NLC; polydispersity index (PDI) lower than 0.2; and zeta potential of –29.4 mV and –29.0 mV, respectively. Interestingly, despite similar physicochemical characteristics, our investigation revealed differences in the encapsulation efficiency of ASTA-NLC and ZEA-NLC (58.0 % vs. 75.5 %, respectively). Obtained NLCs were stable during a 21 day-storage period in the dark at room temperature or at 4 °C. Investigation of gastrointestinal stability showed no change in effective diameter and PDI under gastric conditions while both parameters significantly changed under intestinal conditions. Our results showed for the first time that both ASTA- and ZEA-NLCs intestinal absorption investigated in the in vitro model is significantly increased (in relation to pure compounds) and is affected by the presence of mucus. This study provides useful data about the advantages of using NLC as a delivery system for ASTA and ZEA that might facilitate their applications in the food and pharmaceutical industry.

Abstract
The aim of this study was to compare the effects of dexmedetomidine and dexamethasone as adjuvants to preoperative epidural administration of local anesthetic (ropivacaine) in thoracic surgery on the postoperative level of pain, use of analgesics, inflammation, and oxidative stress. The study enrolled 42 patients who underwent elective thoracic surgery in a one-year period at the University Hospital Dubrava (Zagreb, Croatia). Based on a computer-generated randomization list the patients were assigned to the dexmedetomidine (n = 18) or dexamethasone (n = 24) group. Postoperatively, patients of dexmedetomidine group reported lower pain (VAS value 1 h post surgery, 3.4 ± 2.7 vs. 5.4 ± 1.8, dexmedetomidine vs. dexamethasone, p < 0.01) and had lower anal-gesic requirements in comparison with dexamethasone group. Thus, dexmedetomidine in comparison with dexamethasone was more efficient in lowering pain and analgesia requirements 24 h after the surgery. On the contrary, dexamethasone had better anti-inflammatory properties (CRP level 24 h post surgery, 131.9 ± 90.7 vs. 26.0 ± 55.2 mg L−1, dexmedetomidine vs. dexamethasone, p < 0.01). Both dexmedetomidine and dexamethasone exhibited antioxidant effects, however, their antioxidant properties should be further explored. The results of this study improve current knowledge of pain control in thoracic surgery.

Abstract
Solid-phase extraction (SPE) coupled with capillary electrophoresis (CE) for the determination of macrolide antibiotics (azithromycin, clarithromycin, roxithromycin, tylosin) and tiamulin in water samples was described in this article. These compounds were extracted with different types of sorbents ( Oasis HLB, C18, C8, SDB, and Strata-X) and different masses of sorbents (60 mg, 200 mg, and 500 mg) using different organic solvents (methanol, ethanol, and acetonitrile) and different pH values of water samples (pH 7.00, 8.00, and 9.00). It was found that the highest extraction efficiency of the studied compounds was obtained with 200 mg/3 mL C18 cartridges with methanol as eluent at pH 9.00 of the water sample. The developed SPE-CE method for macrolide antibiotics and tiamulin was validated for linearity, precision, repeatability, the limit of detection (LOD), the limit of quantification (LOQ), and recovery. Good linearity was obtained in the range of 0.3–30 mg L−1 depending on the drug, with correlation coefficients higher than 0.9958 in all cases except clarithromycin (0.9873). Expanded measurement uncertainties were calculated for each pharmaceutical, accounting for 20.31 % (azithromycin), 38.33 % (tiamulin), 28.95 % (clarithromycin), 26.99 % (roxithromycin), and 21.09 % (tiamulin). Uncertainties associated with precision and calibration curves contributed the most to the combined measurement uncertainty. The method was successfully applied to the analysis of production waste-water from the pharmaceutical industry.

Abstract
Treatment adherence is crucial for optimal outcomes in advanced breast cancer, but can be challenging due to various factors, i.e. patients’ attitudes and behavior upon diagnosis, and complex therapies with high adverse effect rates. Our aim was to explore the adherence to oral anticancer medications (OAM) in women with advanced breast cancer, focusing on cyclin-dependent kinase 4 and 6 inhibitors (CDKI), and identify factors associated with the adherence. We conducted a cross-sectional study at the University Hospital Centre Zagreb, Croatia, involving women with stage IV advanced breast cancer receiving OAM. Data collection included a questionnaire assessing socio-demographic and clinical information, Beck Depression Inventory-II for depressive symptoms, Medication Adherence Report Scale (MARS-5) for adherence to OAM, and Beliefs about Medicines Questionnaire. Plasma concentrations of CDKI were confirmed by LC-MS/MS in three randomly selected participants. A total of 89 women were included. The most prescribed OAMs were anti-estrogen (71.3 %) and CDKI (60.9 %). MARS-5 scores (mean: 24.1 ± 1.6) correlated with CDKI plasma concentrations. Forgetfulness was the primary reason for non-adherence (25.9 %). Women receiving CDKI (p = 0.018), without depressive symptomatology (p = 0.043), and with more positive beliefs about medicines were more adherent (p < 0.05). This study enhances understanding of medication adherence in advanced breast cancer and identifies influential factors.

Abstract
Olive leaves as a main byproduct of olive oil and fruit industry are a valuable source of phytochemicals such as polyphenols, with multiple biomedical effects. Apart from leaves, olive branches and stems make up a significant amount of olive waste. It is well known that the drying process and long-term storage affect the stability and concentration of polyphenols present in raw materials. For that matter, two different means of storing olive waste, at room temperature and +4 °C, were compared by determining the content of the polyphenol oleuropein (OLE) in olive leaf, branch, and stem extracts (LE, BE, and SE) by HPLC-DAD method. Total phenols (TPC), o-diphenols (o-DPC), and total flavonoids (TFC) content in extracts were assessed by UV-Vis measurements. LE prepared from leaves stored at +4 °C had the highest OLE content, 30.7 mg g−1 of dry extract (DE). SE from stems stored at +4 °C was the richest in TPC and TFC (193 mg GAE/g DE and 82.9 mg CE/g DE, respectively), due to the higher purity of the extract. The biological activity of extracts was determined on cervical cancer (HeLa), melanoma (A375), metastatic melanoma (A375M) tumor cell lines, and on spontaneously immortalized cell line of keratinocytes (HaCaT), using the MTT assay. The data show that all extracts had a similar dose-dependent effect on cell viability in HeLa cells, while the effect of LE on melanoma A375 and A375M, and HaCaT cells was cell-line dependent.

Formation of a Favorable Filtration Regime of Soils in Saline Areas of the Danube Delta Rice Irrigation Systems
Authors: Turcheniuk Vasil , Rokochinskiy Anatoliy , Kuzmych Lyudmyla , Volk Pavlo , Prykhodko Nataliia 
Published: December 2023

Abstract
The environmental state of rice irrigation systems (RIS) is determined by many factors, including natural ones (soil, topographical, hydrogeological, and climatic factors) and technological ones (irrigation norm, design, and parameters of irrigation and drainage networks, etc). The most significant influence on the ecological reclamation state of the RIS carries is effected by its drainage network (DN). The need to maintain a flushing water regime with specific filtration rates to prevent secondary salinization in the Danube Delta’s rice systems is a crucial aspect of managing these agricultural areas. In the saline areas of rice systems located in the Danube Delta, the DN must ensure the maintenance of the flushing water regime with the rates of filtration ranging between 10 to 12 mm/day. This is a prerequisite for preventing secondary salinization of irrigated lands of these rice systems. According to the results of studies, the filtration from the surface of the irrigation checks of the Danube Delta RIS has been established, and its values in the area of the rice check vary significantly. Different intensity of filtration in the area of rice checks causes the difference in mineralization of groundwater and in the content of salts in the soil. This leads to the fact that the same rice check created various natural reclamation conditions and different productivity of cultivated crops.
Prevalence and risk factors of intestinal parasitic infections among pregnant women in Taiz Governorate, Yemen: A hospital-based study
Authors: Alharazi T. 
Published: December 2023

Summary

Background
Intestinal parasitic infections in pregnant women have been associated with severe adverse outcomes such as anemia, low birth weight, and mother and fetus morbidity and mortality. This study aimed to determine the prevalence of intestinal parasitic infection and its associated risk factors among pregnant women in Taiz, Yemen.

Methods
A cross-sectional study was conducted between July 2022 and January 2023. Sociodemographic and other explanatory variables were obtained via face-to-face interviews using a structured questionnaire. The wet-mount and formol-ether concentration techniques were applied to identify the IPIs. Data were analyzed using SPSS, version 20, and p-values < 0.05 were considered statistically significant. An analysis of descriptive statistics and multivariate logistic regression was conducted. A p-value < 0.05 was deemed statistically significant. The study included a total of 393 pregnant women.

Results
Of the 393 pregnant women screened for intestinal parasites, 144 (36.6 %) had at least one parasite. The most common intestinal parasite was Giardia lamblia (12.2 %), followed by Ascaris lumbricoides (10.9 %), Entamoeba histolytica/dispar (7.4 %), Enterobius vermicularis (14.3 %), and Hymenolepis nana (1.8 %). Being a farmer (AOR = 2.7, 95% CI: 1.69–4.26, p = 0:003) and drinking from unsafe water wells, streams, rain, and dams (AOR = 2:6, 95% CI: 1.68–4.25, p ≤ 0:001) were significantly associated with IPIs.

Conclusion
Pregnant women in the study area still face a severe health burden due to intestinal parasitic infection. Therefore, it is recommended that health education should be improved, and safe tap water should be provided to pregnant women to reduce the incidence of IPIs.
Advancing biomedical engineering: Leveraging Hjorth features for electroencephalography signal analysis

Published: December 2023

Abstract
Biomedical engineering stands at the forefront of medical innovation, with electroencephalography (EEG) signal analysis providing critical insights into neural functions. This paper delves into the utilization of EEG signals within the MILimbEEG dataset to explore their potential for machine learning-based task recognition and diagnosis. Capturing the brain’s electrical activity through electrodes 1 to 16, the signals are recorded in the time-domain in microvolts. An advanced feature extraction methodology harnessing Hjorth Parameters—namely Activity, Mobility, and Complexity—is employed to analyze the acquired signals. Through correlation analysis and examination of clustering behaviors, the study presents a comprehensive discussion on the emergent patterns within the data. The findings underscore the potential of integrating these features into machine learning algorithms for enhanced diagnostic precision and task recognition in biomedical applications. This exploration paves the way for future research where such signal processing techniques could revolutionize the efficiency and accuracy of biomedical engineering diagnostics.
