Selected osteointegration markers in different timeframes after dental implantation: findings and prognostic value.

The study aimed to determine the osteointegration markers after dental implantation and evaluate their predictive value. The study was performed on 60 practically healthy persons who needed teeth rehabilitation using dental implants. The conical-shaped implants (CI) and hexagonal implants (HI) were used. The content of Osteopontin (OPN), Osteocalcin (OC), Alkaline Phosphatase (ALP), Osteoprotegerin (OPG), and nitric oxide (NO) was determined in patients' gingival crevicular fluid (GCF) and peri-implant sulcular fluid (PISF), collected 1, 3, and 6 months after implantation. During the 3-6 months of observation level of OPN increased in patients with CIs (<50 years > 50 years) and HIs (<50 years) (CI: <50 years F = 36.457, p < 0.001; >50 years F = 30.104, p < 0.001; HI < 50 years F = 2.246, p < 0.001), ALP increased in patients with CIs (<50 years: F = 19.58, p < 0.001; >50 years: F = 12.01; p = 0.001) and HIs (<50 years) (F = 18.51, p < 0.001), OC increased in patients <50 years (CI: F = 33.72, p < 0.001; HI: F = 55.57, p < 0.001), but in patients >50 years - on the 3 days month (CI: F = 18.82, p < 0.001; HI: F = 26.26, p < 0.001), but sharply decreased at the end of sixth month. OPG increased during 1-3 months of the observation in patients <50 years (CI: F = 4.63, p = 0.037; HI: F = 2.8927, p = 0.046), but at the end of the sixth month returned to the initial level; NO content in PISF increased in patients with CI (>50 years) during 1-6 months of the observation (F = 27.657, p < 0.001). During the post-implantation period, age-related differences in osteointegration were observed. Patients <50 years old had relatively high levels of OPN, ALP, OC, and OPG in PISF, resulting in less alveolar bone destruction around dental implants and more intensive osteointegration. These indicators may be used as biological markers for monitoring implant healing. The process of osseointegration was more intense in CIs due to their comparatively high mechanical loading.

Possible Markers for Distinguishing benign and Malignant Thyroid Tumors and Predicting Malignancy in Patients with Genetic Predisposition to Cancer.

BACKGROUND: We hypothesized that mutations in several genes disrupt oxidative metabolism, increasing the risk of developing tumors and their malignancy in patients with a family predisposition to cancer. The purpose of our study was to assess the characteristics of oxidative metabolism in patients with malignant and benign tumor with and without a family history of cancer and identify the marker predicting the likelihood of malignancy. METHODS: We conducted a study on patients with thyroid pathology (thyrotoxicosis, benign tumor pathology of the thyroid gland, and thyroid cancer) who underwent treatment at LLC "Oncology Scientific Research Center" in Tbilisi, Georgia between 2020-2021.  In patients' blood the thyroid hormones content, the oxidative metabolism parameters (activity of nonenzymatic antioxidant system (TAA), malondialdehyde (MDA) content),  geometrical and rheological (deformability index (EDI), membrane proteins content) characteristics of erythrocytes were determined. RESULTS: in the patient's blood serum with benign tumor (47 patients) MDA exceeded (p<0.005) and TAA decreased (p<0.005) in comparison to the control level; in patients with thyroid cancer (35 patients), MDA also exceeded (p<0.005), while TAA increased (p<0.005) up to the control level. In patients with benign and malignant tumors, the size of erythrocytes increased compared to the control indicators (p<0.005); in patients with thyroid cancer and benign tumors with a family history of cancer (29 patients) EDI increased (p<0.005), content of GLUT1 in erythrocyte membranes decreased (p<0.005) compared to the control level. CONCLUSIONS: Alterations in redox metabolism play a crucial role in tumor formation; an imbalance between anti-/pro-oxidant systems may contribute to tumor formation and support its progression into a more malignant state. Thyroid cancer is characterized by a reduction in erythrocyte deformability, related to TSH levels. These alterations are less detectable in patients with benign thyroid tumors with a family history of cancer.

Effect of Bioactive Compounds from Pumpkin Powder on the Quality and Textural Properties of Shortbread Cookies.

The problem of food with functional ingredients, characterized by low energy intake and a variety of phytonutrients with biological activity, is one of the concerns of the population. The objectives of this study were to investigate the effect of pumpkin powder and its bioactive components on the quality, color and textural properties of shortbread cookies. In the drying process of pumpkin powder (Cucurbita moschata) at 60 ± 2 °C, the physicochemical parameters did not change significantly in relation to fresh pulp. The chromatic parameters L*, a* and b* showed that the pumpkin powder was brighter than the pulp, with a greater presence of yellow pigments. Pumpkin powder presented a rich source of bioactive compounds (polyphenols flavonoids, carotenoids) with an antioxidant potential of 161.52 mmol TE/100 g DW and 558.71 mg GAE/100 g DW. Antimicrobial activity against Gram-positive (Staphylococcus aureus, Bacillus cereus), Gram-negative (Escherichia coli, Salmonella Abony and Pseudomonas aeruginosa) bacteria and high antifungal activity against Candida albicans were attested. The sensory, physicochemical, texture parameters and color indicators of shortbread cookies with yellow pumpkin powder (YPP) added in a proportion of 5-20% were analyzed. The optimal score was given to the sample of 15% YPP. The use of 15-20% YPP contributed to improved consistency due to the formation of complexes between starch and protein.

Impact of the Angiotensin-Converting Enzyme (ACE) Inhibitors on the Course of the Acute Respiratory Distress Syndrome (ARDS) Developed During COVID-19 and Other Severe Respiratory Infections Under Hyperferritinemia Conditions: A Cohort Study.

Background: Angiotensin-converting enzyme 2 (ACE2) is not only the entry route of SARS-CoV-2 infection but also triggers a major mechanism of COVID-19 aggravation by promoting a hyperinflammatory state, leading to lung injury, hematological and immunological dysregulation. The impact of ACE2 inhibitors on the course of COVID-19 is still unclear. The effect of ACE2 inhibitors on the course of acute respiratory distress syndrome (ARDS) during COVID-19 and other severe respiratory infections in conditions of hyperferritinemia (HF) was investigated. Methods: A cohort study of critically ill patients with COVID-19 and other respiratory diseases (widespread infection, pneumonia) who underwent treatment in The Critical Care Unit of the First University Clinic (Tbilisi, Georgia) during the 2020-2021 years was conducted. The impact of the ACE2 inhibitors on the course of the ARDS developed during COVID-19 and other severe respiratory infections in conditions of different severity of HF was evaluated. Results: In COVID-19-infected (I) and uninfected (II) patients with ARDS, ACE2 inhibitors reduce the levels of Ang II, C reactive protein (CRP) and D-dimer (I: from 1508.07 ± 26.68 to 48.51 ± 24.35, from 233.92 ± 13.02 to 198.12 ± 11.88, from 7.88 ± 0.47 to 6.28 ± 0.43; II: from 1000.14 ± 149.49 to 46.23 ± 88.21, 226.48 ± 13.81 to 183.52 ± 17.32, from 6.39 ± 0.58 to 5.48 ± 0.69) at moderate HF and Ang II, CRP levels (I: from 1845.89 ± 89.37 to 49.64 ± 51.05, from 209.28 ± 14.41 to 175.37 ± 9.84; II: from 1753.29 ± 65.95 to 49.76 ± 55.74, 287.10 ± 20.50 to 214.71 ± 17.32) at severe HF, reduce interleukin-6 (IL-6) expression at moderate HF (I: from 1977.23 ± 354.66 to 899.36 ± 323.76) and cause reduction of pCO2 index at severe HF (I: from 69.80 ± 3.22 to 60.44 ± 2.20) in COVID-19-infected patients. Conclusion: Study results show that the ACE2 inhibitors play an important role in the regulation of inflammatory processes in both COVID-19-infected and uninfected patients with ARDS. ACE2 inhibitors decrease immunological disorders, inflammation, and lung alveoli dysfunction, especially in COVID-19-infected patients.

Study of blood rheological parameters and NO in coronary artery disease patients with and without collaterals.

BACKGROUND: In coronary artery disease (CAD), an alternative way of improvement of blood circulation in the ischemic area of the myocardium is coronary collateral circulation. Our study aimed to investigate the rheological parameters of blood and nitric oxide (NO) content in patients with various degrees of collateral development and the likelihood of the influence of blood fluidity on collateral angiogenesis. METHODS: We studied patients with stable CAD who underwent elective coronary angiography and a control group with the same mean age. We investigated patients with different degrees of developing collaterals and those without them. In studied patients, the blood plasma viscosity, aggregability, and deformability of erythrocytes, as the main indicators of blood rheology. We recorded content of stable metabolic end products of nitric oxide (NOx). RESULTS: Results of the studies showed that in the blood of studied patients with CAD erythrocyte aggregation was increased and NO content decreased compared to the control level; NO content was as lower, as less was the number of developed collaterals was recorded. CONCLUSION: In this work, the role of the aggregation ability of erythrocytes and the endothelial origin of NO in the direct and feedback regulatory mechanism of angiogenesis in patients with CAD are discussed.

Parallel study of the rheological status, vascular changes and intracardiac hemodynamics in heart failure in coronary artery disease.

BACKGROUND: Ischemic heart disease is a pathological chronic and acute condition, which is provoked by insufficient blood supply or its complete cessation. To reduce the number of patients, all approaches and studies that can positively affect the prevention and treatment of the disease are important. This is very important in monitoring and treating diseases of all systems and organs, especially in diseases of the cardiovascular system. The aim of our work was to elucidate the relationship between the rheological status of blood, vascular changes and intracardiac hemodynamics in heart failure in coronary artery disease patients with different functional classes. OBJECTIVES: The aim of our work was to elucidate the relationship between the rheological status of blood, vascular changes and intracardiac hemodynamics in heart failure in coronary artery disease patients with different functionalclasses. METHODS: We examined 76 men and women patients with coronary artery disease - I-IV functional class (by New York Heart Association Functional Classification NYHA)), mean age - 59.2±4 years. The control group consisted of 20 apparently healthy volunteers (Woman: Man -1:1), whose average age was 52±3 years. Representatives of the control group did not take any medication during the study period and were apparently healthy. The electrocardiogram of the subjects in the control group corresponded to the norm. All subjects underwent clinical and laboratory studies in a standard way: to describe the rheological status of blood, the erythrocyte aggregability index (EAI), erythrocyte deformability index (EDI), and plasma viscosity were determined; to assess vascular changes - resistance index of resistive arteries (RIRA); to study intracardiac hemodynamics, echocardiology was performed according to the recommendations proposed by the American Association of Physicians. RESULTS: Rheological changes are present from the very beginning of the disease and progress along with the severity of the disease. Therefore, it is possible to assess the severity of the disease based on rheological disorders, which can precede the onset of ischemic heart disease. The vascular status resistance index increases in the early stages of the disease, with I functional class - RIRA increased by 46%. The cardiac index, which determines the adequacy of the global perfusion pressure, is the main indicator of hemodynamics and is negatively related to the increase in erythrocyte aggregation, although this indicator turned out to be statistically unreliable. CONCLUSION: The interpretation of our data will allow us to better understand the pathogenesis of heart failure, as well as recommend a list of tests, and methods that were discussed in the article to assess the clinical condition of patients. Continuing research in the same direction, we believe that we will be able to make adjustments to research methods and to the algorithm for drug therapy.

Comprehensive study of the rheological status and intensity of oxidative stress during the progression of type 2 diabetes mellitus to prevent its complications.

BACKGROUND: Prevention of Type 2 diabetes mellitus (T2DM) requires a modifying effect on the pathological processes inducing the ß-cell dysfunction. OBJECTIVES: the comprehensive study of the violation of rheological parameters in patients with different stages of diabetes and identification of possible links between these alterations with the intensity of the oxidative stress in the patient's body. METHODS: 60 patients with IR, prediabetes, T2DM and healthy volunteers were included. Full range of the rheological parameters of the patients' blood - the indicators of erythrocytes aggregation index (EAI), the relative deformability of the erythrocytes membranes (ERDI), blood plasma viscosity (BPV), and oxidative stress intensity (OSI) were examined. RESULTS: In patients with insulin resistance (IR), prediabetes, and T2DM the ERDI was statistically significantly lower and BPV - higher compared to control; a significant increase in EAI was detected in the patient group with prediabetes and T2DM compared to the control. CONCLUSION: The level of rheological disorders in patients increases with the increase of the level of carbohydrate metabolism disorders and intensity of oxidative stress and reaches a maximum during manifested diabetes. Diagnosis of hemorheological disorders and OSI in T2DM can serve as an early marker of target organ damage possibility.

Role of ABO Blood Groups in Susceptibility and Severity of COVID-19 in the Georgian Population.

Aim and objective: The establishment of the potential role of the infected people's ABO blood type in the virus infectivity and aggressivity could clarify the aspects of the various susceptibility to virus and play a key role in assessing its spreading potential in the future. We studied the possible association of risk of coronavirus disease-2019 (COVID-19) infection and severe outcomes of disease with ABO blood groups and Rh factor in the Georgian population. Materials and methods: The effect of blood type on the severity of infection in COVID-19 positive patients admitted to the First University Clinic of Tbilisi State University (Tbilisi, Georgia) from December 2020 to September 2021 was analyzed retrospectively. The odds ratio (OR) criterion was used to determine the influence of the blood group on the risk of COVID-19 infection and of severe course of the disease. Results: The incidence of COVID-19 was 1.65-fold higher in the patients with blood group II(A), and average twice lower in patients with blood groups III(B) and IV(AB), compared with the ABO blood group distribution in healthy donors of the region. The percentage of patients transferring in ICU with I(O) and II(A) blood groups was enough high (42-40%), whereas in patients with III(B) and IV(AB) blood groups very low (12-6%). There were not revealed any statistically significant differences in the distribution of the patients with Rh+ and Rh- blood groups in healthy and COVID-19 infected individuals (including those transferred in the ICU). Conclusion: The link between patients' ABO blood groups and receptivity to COVID-19 infection, progression and severity of the disease, has been detected. These results are relevant in terms of elucidating the mechanisms and risk factors of infecting and severity course of COVID-19 disease.

Complex study of Cancer Morbidity and Inflammatory Markers, Presented in the Blood Serum of the Rural Population of Sachkhere District of Georgia.

AIM: The purpose of the study was to compare the morbidity from cancer (expressed as incidence) to the average levels of blood serum inflammatory markers in the population of the Sachkhere region (Georgia). METHODS: healthy residents of the Sachkhere district were examined. In the blood serum samples of patients, the cytokines (IL-1α, IL-10, TGF-ß, IL-12, IL-17, TNF-α, IL-6) and NOx content, as well as the total antioxidant activity of the non-enzymatic system (TAA) were determined; using light microscopy, buccal micronuclei (MnB) of epithelial cells of the oral mucosa, as indicators of chromosomal disorders, were studied. RESULTS: Study results show, that cancer incidence in Sareki was statistically significantly higher as in Chorvila and Sairkhe (p=0.002; p=0.004); in Sareki inhabitant's blood serum levels of the IL-6,  NO are increased (p=0.004, p=0.05), and IL-17,  TGFß, and IL-10 levels are decreased (p=0.010, p=0.001, p=0.033) in comparison to data in Chorvila; in Chorvila inhabitants' indicators of TAA  of blood serum and  MnB of epithelium cell levels were lower (p=0.001,p=0.045) then in Sairkhe and Sareki. CONCLUSION: The existence of statistically reliable associations between the levels of cancer incidence in the populations of the surveyed villages and the indicators of immune and oxidative status in their virtually healthy subpopulations, with a high degree of persuasiveness, allows us to assume a close causal link between them. Clarifying the reasons for the identified patterns and their significance requires more detailed studies.

The Alleviating Effect of Herniarin Against Ionizing Radiation-Induced Genotoxicity and Cytotoxicity in Human Peripheral Blood Lymphocytes.

BACKGROUND AND OBJECTIVE: Herniarin is a simple coumarin that is found naturally in some plant species. In this study, we aimed to evaluate the protective effect of herniarin against ionizing radiation-induced genotoxicity and cytotoxicity in human peripheral blood lymphocytes. METHODS: Herniarin was added to human lymphocytes before irradiation with a dose of 2 Gy of Xrays. The antagonistic potential of herniarin against radiation was measured by MTT [3-(4,5- dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide] assay, micronucleus assay, flow cytometry, and reactive oxygen species (ROS) level analysis. RESULTS: The maximum survival of lymphocytes against radiation was observed at a concentration of 50 µM of herniarin and a treatment time of 1 h. Pretreatment with 50 µM herniarin significantly decreased the micronuclei frequency, the percentage of apoptotic lymphocytes, and the ROS level in irradiated human lymphocytes. Moreover, 50 µM herniarin significantly increased the cytokinesis blocked proliferation index in irradiated lymphocytes. CONCLUSION: Herniarin could reduce radiation-induced cytotoxicity and genotoxicity in human lymphocytes. To complete the results of this study, it is suggested that in the future, more preclinical studies with larger samples or animal models be performed on herniarin.

Some Aspects of Role of Nitric Oxide in the Mechanisms of Hypertension (Experimental Study).

BACKGROUND: Modulation of endothelial function is a therapeutic option to reduce some of the significant complications of hypertension. However, the relationship between endothelial dysfunction reduced nitric oxide (NO) production, and the development of hypertension is not fully understood. To establish a potential pathogenetic link between impaired NO synthesis and hypertension, we investigated the results of competitive interaction of the substrate of NO synthase, L-arginine, and its analog, an non-selective inhibitor of NO synthase, N-nitro-methyl ether-L-arginine (L-NAME), in experimental rats. METHODS: Arterial hypertension was induced in male Wistar rats by intraperitoneal administration of L-NAME (Sigma-Aldrich) for 4 - 7 weeks. During the last 3 weeks, to a separate group of animals simultaneously with L-NAME, L-arginine (Sigma-Aldrich) was administered. In animals monitored for systolic and diastolic pressure, the level of NO in blood samples was determined spectrophotometrically using a Griess reagent. RESULTS: Administration of L-NAME for 4 - 7 weeks induced an irreversible decrease of NO content in blood, a reversible increase of systolic pressure (SP) and diastolic pressure (DP), and an irreversible increase in pulse pressure (PP). In rats against the background of 7 weeks of intraperitoneal administration of L-NAME, during the last 3 weeks, they were injected with L-arginine, the SP and DP indices returned to their initial values, PP decreased and the NO content in arterial blood increased. CONCLUSIONS: The results of the study indicate the presence of residual endothelial dysfunction (characterized by insufficient NO) after the correction of hypertension. Therefore, in developing the new therapeutic approaches for the treatment of hypertension, it is necessary to include drugs that, in addition to correcting blood pressure, will support normalization, and potentiation of endothelial function and endogenous NO synthesis.

Constituents of French Marigold (Tagetes patula L.) Flowers Protect Jurkat T-Cells against Oxidative Stress.

The flowers of French marigold (Tagetes patula L.) are widely used in folk medicine, in particular for treating inflammation-related disorders. However, cellular mechanisms of this activity demand further investigation. In the present work, we studied the potential of T. patula compounds to alleviate the oxidative stress in hydrogen peroxide-challenged human lymphoblastoid Jurkat T-cells. Crude extracts of marigold flowers and purified fractions containing flavonoids patuletin, quercetagetin, and quercetin and their derivatives, as well as the carotenoid lutein, were brought in contact with Jurkat cells challenged with 25 or 50 µM H2O2. Hydrogen peroxide caused oxidative stress in the cells, manifested as generation of superoxide and peroxyl radicals, reduced viability, arrested cell cycle, and enhanced apoptosis. The stress was alleviated by marigold ingredients that demonstrated high radical-scavenging capacity and enhanced the activity of antioxidant enzymes involved in neutralization of reactive oxygen species. Flavonoid fraction rich in quercetin and quercetagetin showed the highest cytoprotective activity, while patuletin in high dose exerted a cytotoxic effect associated with its anticancer potential. T. patula compounds enhanced the production of anti-inflammatory and antioxidant interleukin-10 (IL-10) in Jurkat cells. Both direct radical-scavenging capacity and stimulation of protective cellular mechanisms can underlay the anti-inflammatory properties of marigold flowers.

Rosmarinic acid-rich extracts of summer savory (Satureja hortensis L.) protect Jurkat T cells against oxidative stress.

Summer savory (Satureja hortensis L., Lamiaceae) is used in several regions of the world as a spice and folk medicine. Anti-inflammatory and cytoprotective effects of S. hortensis and of its rosmarinic acid-rich phenolic fraction have been demonstrated in animal trials. However, previous studies of rosmarinic acid in cell models have yielded controversial results. In this study, we investigated the effects of summer savory extracts on H2O2-challenged human lymphoblastoid Jurkat T cells. LC-MS analysis confirmed the presence of rosmarinic acid and flavonoids such as hesperidin and naringin in the phenolic fraction. Adding 25 or 50 µM of H2O2 to the cell culture caused oxidative stress, manifested as generation of superoxide and peroxyl radicals, reduced cell viability, G0/G1 arrest, and enhanced apoptosis. This stress was significantly alleviated by the ethanolic and aqueous extracts of S. hortensis and by the partially purified rosmarinic acid fraction. The application of an aqueous S. hortensis extract doubled the activity of catalase and superoxide dismutase in the cells. The production of IL-2 and IL-10 interleukins was stimulated by H2O2 and was further enhanced by the addition of the S. hortensis extract or rosmarinic acid fraction. The H2O2-challenged Jurkat cells may serve as a model for investigating cellular mechanisms of cytoprotective phytonutrient effects.

Neuroprotective treatment of cerebral infarction: an experimental study.

We investigated the effect of the amniotic-derived peptide Plaferon-LB on cerebral tissue damage during photochemical insults in rats. Plaferon-LB (US patent number: 20070123467 A1) was extracted from the amniochorionic membrane of a human placenta and showed a relatively strong antihypoxic effect compared to other interferon. Thrombotic infarction was induced by photochemical illumination after intravenous injection of Rose Bengal. The infarct volume, cerebral tissue oxygen tension, cerebral blood flow, and capillary damage were measured in the following groups: untreated control rats, Plaferon-LB-alone rats, insult-alone rats, and insult in Plaferon-LB pretreated rats. The technique of electron paramagnetic resonance (EPR) spectroscopy was used to study free-radical metabolites in the blood and brain tissue ex vivo. Plaferon-LB alone had no effect on systemic blood pressure, cerebral blood flow, and reactive metabolites in the brains of intact animals. In the insult-alone group, a focal hemorrhage was observed in the ischemic area. The cerebral blood flow and tissue oxygen pressure declined to zero within an hour and remained at this level throughout the insult. The treatment with Plaferon-LB 0.5 hr before illumination resulted in a significant reduction of the median infarct size in the insult-alone group. The total length and percentage ratio of thrombotic vessels were significantly diminished in the infarct area. The intensity of Fe2+, Mn2+ -, Mo5+ -xanthinoxidase-containing complexes, and nitric oxide EPR signals was decreased, and the electron transport in the mitochondria was normalized. The results indicate a significant beneficial effect of Plaferon-LB on cerebral infarct, which is likely due to its antioxidative properties.

Selected acute phase CSF factors in ischemic stroke: findings and prognostic value.

BACKGROUND: Study aimed at investigation of pathogenic role and prognostic value of several selected cerebrospinal fluid acute phase factors that can reflect the severity of ischemic brain damage. METHODS: Ninety five acute ischemic stroke patients were investigated. Ischemic region visualized at the twenty fourth hour by conventional Magnetic Resonance Imaging. Stroke severity evaluated by National Institute Health Stroke Scale. One month outcome of disease was assessed by Barthel Index. Cerebrospinal fluid was taken at the sixth hour of stroke onset. CSF pro- and anti-inflammatory cytokines were studied by Enzyme Linked Immunosorbent Assay. Nitric Oxide and Lipoperoxide radical were measured by Electron Paramagnetic Resonance. CSF Nitrate levels were detected using the Griess reagent. Statistics performed by SPSS-11.0. RESULTS: At the sixth hour of stroke onset, cerebrospinal fluid cytokine levels were elevated in patients against controls. Severe stroke patients had increased interleukin-6 content compared to less severe strokes (P < 0.05). Cerebrospinal fluid Electron Paramagnetic Resonance signal of nitric oxide was increased in patients against controls. Severe stroke group had an elevated Electron Paramagnetic Resonance signal of lipoperoxiradical compared to less severe stroke. Cerebrospinal fluid nitrate levels in less severe stroke patients were higher than those for severe stroke and control. Positive correlation was established between the initial interleukin-6 content and ischemic lesion size as well as with National Institute Health Stroke Scale score on the seventh day. Initial interleukin-6 and nitrate levels in cerebrospinal fluid found to be significant for functional outcome of stroke at one month. CONCLUSION: According to present study the cerebrospinal fluid contents of interleukin-6 and nitrates seem to be the most reliable prognostic factors in acute phase of ischemic stroke.
