This research aims at determining the loading of contamination of some popular brands of extra-virgin olive oil (EVOO) in Port Harcourt, Nigeria, with genotoxic PAHs and Heavy Metals to ascertain its safety for consumption. The health risk associated with these heavy metals will be calculated and assessed. Extra virgin olive oil has experienced a surge in its consumption all around the world owing to its high nutritional content. Contamination with genotoxic PAHs and Heavy Metals can cause severe health defects if consumed regularly. PAHs and heavy metals are two distinct groups of ubiquitous contaminants with grave health consequences such as Tumorigenesis, carcinogenesis, organ failures etc. Samples of EVOO were analysed with Gas Chromatography/Mass Spectrophotometer and Flame Atomic Absorption Spectrophotometer (FAAS) for PAHs and heavy metals respectively. After extraction with Dichloromethane and digestion with aqua regia (HCl/HNO3; 3:1) respectively, the results showed the presence of few genotoxic PAHs such as benzo[a]pyrene, PAH4 and PAH8 with concentrations above regulatory limits of 0.002µg/g, 0.01µg/g and 0.01µg/g respectively. Among the heavy metals, Pb and Cd showed the most alarming levels of contamination of the heavy metals, above regulatory limits of 0.1µg/g and 0.05µg/g, however, analysis with Health Risk Index of consumption showed all samples were safe for consumption.

The comparison group consisted of 85 patients with ischemic stroke without COVID-19 in the history (46 men and 39 women), mean age 65.9±4.8 years. The control group included relatively healthy individuals (n=20; mean age 52.4±6.5 years). RESULTS. The vegetative index of blood circulation at admission in patients who died in the acute period (according to the Rankin scale of 6 points) was characterized by a clear predominance of sympathicotonia (1.86 cu.), which became even more predominant on day 7 (2.32 cu.), remaining somewhat less pronounced until death (1.45 cu.). A decrease in the vegetative index of blood circulation against the background of high NIYSS and Rankin scores indicates the depletion of the autonomic nervous system against the background of prolonged pronounced sympathicotonia. The vegetative index of blood circulation in patients with moderate ischemic stroke on the Rankin scale corresponded to moderate sympathicotonia (1.38 cu) and in dynamics, on the 7th and 14th days of hospital stay, decreased quantitatively – 1.27 and 1.13 cu, respectively. CONCLUSION. The obtained results showed that against the background of stabilization of vegetative homeostasis there was a positive neurological dynamic. In this category of patients, the average Kerdo index according to Charlson and CIRS scales was also recorded 6.2 and 5.6, respectively. In patients with a good outcome of ischaemic stroke according to the Rankin scale, the autonomic circulatory index (ICI) at hospital admission was characterized by moderate sympathicotonia (1.26 u.u.), on the 7th and 14th day of hospital treatment the ICI was 1.16 and 1.09 u.u., respectively. In this category of patients, the Charlson IR and CIRS scale scores were 3.1 and 3.9, respectively (with significant intergroup differences). KEYWORDS: stroke, COVID-19, autonomic nervous system

INTRODUCTION. A decrease in heart rate variability indicates a violation of the autonomic control of cardiac activity, which is one of the reasons for the poor prognosis in this category of patients. Until now, the problem of the effectiveness and safety of correction of high blood pressure during the acute period of ischemic stroke remains a subject of debate. AIM. To determine clinical, autonomic and hemodynamic changes at rest and during an active orthostatic test to assess the functional state and adaptive capabilities of the cardiovascular system and identify risk factors for the unfavorable course of arterial hypertension in patients with hypertension in the acute period of ischemic stroke. MATERIAL AND METHODS. 78 patients with hypertension who were treated in a therapeutic hospital were examined. The first group consisted of 40 people with hypertension complicated by ischemic stroke, the second group included 38 people with uncomplicated hypertension. The patient's condition was assessed using the NIHSS scale and the Rankin scale. data from electrocardiography, duplex scanning of blood vessels, computed tomography of the brain, transthoracic ECHO-CG, portable monitor VNS-Micro and Poly-Spectrum SM from Neurosoft. The study of heart rate variability was carried out in patients with stroke upon admission, on days 5-10 and before discharge from the hospital (days 15-21). With the Revermead mobility index, more than 7 patients underwent an active orthostatic test with parallel ECG recording, measurement of blood pressure and heart rate at rest and when moving to a vertical position. RESULTS AND DISCUSSION. Patients with insufficient recovery of neurological functions on days 5-7 of stroke demonstrate the development of hypotension during an orthostatic test. An active orthostatic test on days 15-21 of stroke is successfully performed by patients with increased tone of the sympathetic nervous system. Patients with good recovery of neurological functions at discharge have normal autonomic reactivity and an adequate response of the sympathetic division of the autonomic nervous system to standing. CONCLUSION. Young men with hypertension should be closely monitored by physicians and receive primary stroke prevention. To increase tolerance to physical activity in patients who did not complete an active orthotest on days 5-7 of a stroke, daily passive verticalization is necessary.

The primary aim of this study was to empirically examine the contribution of the Innovative Indigenous Product (IIP) approach in enhancing the marketing performance of MSMEs supported by P3UD in Deli Serdang District, North Sumatra. Through the distribution of questionnaires to 98 MSME participants and the application of Smart-PLS 3.0 for analysis, the results reveal that IIP significantly contributes to the relationship between market orientation and marketing performance, suggesting that market orientation indirectly influences marketing performance by fostering IIP. These findings highlight the importance for MSMEs to explore innovative products and services rooted in local culture, which not only boosts marketing performance but also fosters sustainable competitiveness. Additionally, the results suggest that government support plays a critical role in shaping the relationship between market orientation and marketing performance. Overall, the mediation and moderation effects underscore the significance of contingency factors as indispensable elements in efforts to enhance marketing performance.

The research aimed to know The impact of the Corona pandemic on the revenues and expenditures of the Jordanian general government and the gross domestic product
And reached the following results: The Corona Covid-19 pandemic is greater than being limited to a health crisis, it is a humanitarian disaster that led to changes and transformations that attacked the heart of societies and their economies, so it was imperative for countries to work on the continuity of economic activity and the preservation of the wheel of production in the country while limiting the spread of the disease. It led to a complete and total halt to any economic activity, which caused the cancellation of many capital expenditures scheduled in the context of strict measures, as the restrictions imposed on travel and trade resulted in a decrease in revenues and an increase in expenditures, and the Corona pandemic caused an increase in the deficit rate in the state's general budget, as a result of the large expenses incurred by the state, with a clear decrease in annual revenues, but the state was able in the years following the pandemic to reduce the deficit rate in the budget and cancel many capital expenditures and freeze the performance of some economic activities, which is considered a severe blow to the domestic product, considering that revenues and expenditures enable the state to play its role effectively, as the decrease in revenues and the increase in expenditures call for a review of the structure of government institutions and the duties assigned to them The services it provides, which calls for a mix of its services to ensure mitigation of the pandemic and any crisis that the country may be exposed to, which confirms the validity of the first hypothesis and in light of such crises, and practicing that pivotal role that links the actors in the economic sectors, which allows them to be stronger than before, which confirms the validity of the second hypothesis. They recommended the following: Establishing permanent centers for crisis and risk management at the state level and at the level of the various economic sectors, and activating coordination between them to deal with various crises and risks, and developing training programs for workers on how to deal with crises and how to deal with their effects, and appointing experts and specialists to monitor, analyze and prepare reports on the various crises that the various sectors are going through and building a comprehensive database to predict crises before they occur. 10- Strengthening relations between the various governmental, civil and economic sectors with the media institutions due to their importance in spreading awareness and participating in conferences and interviews that help spread knowledge, and the need to benefit from the experiences of other countries in how to overcome crises.
