AB  - Objective: Metabolic changes in insulin-dependent diabetes mellitus (IDDM) impair vasodilation, and this leads to tissue hypoxia and microvascular pathology. Hyperbaric oxygen therapy (HBOT) can significantly improve the outcome of ischemic conditions in IDDM patients and reduce vascular complications. The aim of our study was to assess the effects of HBOT on plasma fatty acid (FA) composition, and expression of insulin-like growth factor binding protein 1 (IGFBP-1) in IDDM patients. Methods: Our study included 24 adult IDDM patients diagnosed with peripheral vascular complications. The patients were exposed to 10 sessions of 100% oxygen inhalation at 2.4 atmosphere absolute for 1 hour. Blood samples were collected at admission and after HBOT for measurement of metabolic parameters, FA composition and IGFBP-1. Measurement of plasma FA composition was determined by gas chromatography. Expression of IGFBP-1 in the serum was estimated by Western blot analysis. Results: HBOT decreased blood levels of total cholesterol (p<0.05), triglycerides (p<0.05) and low-density lipoprotein (p<0.05). HBOT increased plasma levels of individual FAs: palmitic acid (p<0.05), palmitoleic acid (p<0.05), docosapentaenoic acid (p<0.05) and docosahexaenoic acid (p<0.01), and decreased levels of stearic acid (p<0.05), alpha linolenic acid (p<0.05) and linoleic acid (p<0.01). Expression of IGFBP-1 (p<0.01) was increased, whereas the level of insulin (p<0.001) was decreased in the serum after HBOT. Conclusions: Our results indicate that HBOT exerts beneficial effects in IDDM patients by improving the lipid profile and altering FA composition. © 2019 Canadian Diabetes Association

AB  - Hypothyroidism is a common endocrine disorder that predominantly occurs in females. It is associated with an increased risk of cardiovascular diseases (CVD), but the molecular mechanism is not known. Disturbance in lipid metabolism, the regulation of oxidative stress, and inflammation characterize the progression of subclinical hypothyroidism. The initiation and progression of endothelial dysfunction also exhibit these changes, which is the initial step in developing CVD. Animal and human studies highlight the critical role of nitric oxide (NO) as a reliable biomarker for cardiovascular risk in subclinical and clinical hypothyroidism. In this review, we summarize the recent literature findings associated with NO production by the thyroid hormones in both physiological and pathophysiological conditions. We also discuss the levothyroxine treatment effect on serum NO levels in hypothyroid patients. © 2020 The Authors

AB  - Primary hypothyroidism can affect lipid metabolism, cardiovascular (CV) function, and overall patients’ quality of life (QoL). Decrease in serum nitric oxide (NO) levels could promote the atherosclerosis acceleration in hypothyroid patients. Our hypothesis is that serum NO level is altered in hypothyroidism; more specifically, we hypothesize that the early vascular changes that can be observed in hypothyroidism could be due to these alterations and that serum NO levels are associated with lipid levels in female patients diagnosed with subclinical hypothyroidism (SCH) or clinical hypothyroidism (CH). Furthermore, since serum NO level is an early marker of atherosclerosis and related CV disorders, which are commonly present and follow hypothyreosis and greatly contribute to overall QoL, we further hypothesized that NO level would correlate with Thyroid Symptom Questionnaire (TSQ) and General Health Questionnaire 12 (GHQ12) scores in hypothyroid patients. A collaterally of our hypothesis was that levothyroxine (LT4) treatment would affect serum NO levels as well as TSQ and GHQ12 scores. Therefore, we have analyzed lipid profile, the level of NO and QoL scores in female patients diagnosed with SCH and CH in order to determine the correlation between NO and generic and thyroid disease symptoms in treatment naïve SCH and CH patients and after LT4 treatment and laboratory euthyroidism achievement. As a consequence of our hypothesis is that measurement of serum NO level in SCH and CH patients may be an innovative way to improve LT4 treatment efficacy. This assumption could have a practical significance for future investigations regarding the management of hypothyroidism treatment protocols in current guidelines. © 2019 Elsevier Ltd

AB  - This study aimed at examining the early effects of hyperbaric oxygen therapy (HBOT) on inducible nitric oxide synthase (iNOS) activity/expression in lymphocytes of type 1 diabetes mellitus (T1DM) patients. A group of 19 patients (mean age: 63 ± 2.1) with T1DM and with the peripheral arterial disease were included in this study. Patients were exposed to 10 sessions of HBOT in the duration of 1 h to 100% oxygen inhalation at 2.4 ATA. Blood samples were collected for the plasma C-reactive protein (CRP), plasma free fatty acid (FFA), serum nitrite/nitrate, and serum arginase activity measurements. Expression of iNOS and phosphorylation of p65 subunit of nuclear factor- κ B (NF κ B-p65), extracellular-regulated kinases 1/2 (ERK1/2), and protein kinase B (Akt) were examined in lymphocyte lysates by Western blot. After exposure to HBOT, plasma CRP and FFA were significantly decreased ( p < 0.001 ). Protein expression of iNOS and serum nitrite/nitrate levels were decreased ( p < 0.01 ), while serum arginase activity was increased ( p < 0.05 ) versus before exposure to HBOT. Increased phosphorylation of NF κ B-p65 at Ser 536 ( p < 0.05 ) and decreased level of NF κ B-p65 protein ( p < 0.001 ) in lymphocytes of T1DM patients were observed after HBOT. Decreased phosphorylation of ERK1/2 ( p < 0.05 ) and Akt ( p < 0.05 ) was detected after HBOT. Our results indicate that exposure to HBO decreased iNOS activity/expression via decreasing phosphorylation of ERK1/2 and Akt followed by decreased activity of NF κ B.

AB  - Nitric oxide (NO) is a free radical which, in reactions with various molecules causes multiple biological effects. NO is exceptionally regulated and extends to almost every cell type and function within circulation. Generation and actions of NO are regulated by various hormones under physiological and pathophysiological conditions. Nitric oxide synthases (NOS) are the enzymes responsible for NO generation. In mammals, neuronal NOS (nNOS) and endothelial NOS (eNOS) are constitutively expressed, while inducible NOS (iNOS) mediate in immune defense. Altered NO level is associated with obesity, insulin resistance (IR), diabetes and cardiovascular diseases (CVD). Disturbances in eNOS and iNOS regulation accompany multiple changes in endothelial function and contribute to development of CVD. Furthermore, key step in initiation and progression of atherosclerosis is reduction in bioactivity of endothelial cell-derived NO. Here we shall focus on recent literature data related to the role of eNOS and iNOS in physiological and pathophysiological conditions. © 2018 Nova Science Publishers, Inc. All rights reserved.

AB  - Introduction. Chronic liver diseases (CLD) are an important cause of morbidity and mortality in general population. The aim of this study was to analyze potential differences between patients with CLD and healthy control group, and to estimate the severity of CLD by using simple questionnaires: general health questionnaire (GHQ-12) and chronic liver disease questionnaire (CLDQ). Methods. A cross-sectional pilot study was performed in Zemun Clinical Hospital during years 2014 and 2015. Sixty participants were divided into 4 groups (15 per group): chronic alcoholic hepatitis, other chronic hepatitis, liver cirrhosis, and healthy control group. Entire study population chose one of four offered answers of structured questionnaires GHQ-12 and CLDQ, based on which mean model of end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores were calculated. Results. Mean GHQ12 and CLDQ scores were 10.5 and 5.21 +/- 1.11 respectively. Regarding certain CLDQ domain scores, a significant difference between alcoholic and non-alcoholic hepatitis groups in the worry domain was observed. Mean MELD score was 7.42 +/- 2.89 and did not differ between chronic hepatitis groups, while mean CTP score was 5.73 +/- 0.88. A statistically significant correlation was observed between GHQ12 and CLDQ scores (rho = -0.404, p LT 0.01), but not between subjective and objective scores. Conclusions. Mean GHQ12 and CLDQ scores pointed out to general psychological no-distress condition of the studied participants, as well as scarcely expressed CLD-specific complaints. Mean MELD and CTP scores indicated stable chronic liver diseases, with low three-month mortality rates in the cases of chronic hepatitis, as well as determination to Child A group in the case of liver cirrhosis.

The aim of this study was to analyze potential differences between patients with CLD and healthy control group, and to estimate the severity of CLD by using simple questionnaires: general health questionnaire (GHQ-12) and chronic liver disease questionnaire (CLDQ). Methods. A cross-sectional pilot study was performed in Zemun Clinical Hospital during years 2014 and 2015. Sixty participants were divided into 4 groups (15 per group): chronic alcoholic hepatitis, other chronic hepatitis, liver cirrhosis, and healthy control group. Entire study population chose one of four offered answers of structured questionnaires GHQ-12 and CLDQ, based on which mean model of end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores were calculated. Results. Mean GHQ12 and CLDQ scores were 10.5 and 5.21 +/- 1.11 respectively. Regarding certain CLDQ domain scores, a significant difference between alcoholic and non-alcoholic hepatitis groups in the worry domain was observed. Mean MELD score was 7.42 +/- 2.89 and did not differ between chronic hepatitis groups, while mean CTP score was 5.73 +/- 0.88. A statistically significant correlation was observed between GHQ12 and CLDQ scores (rho = -0.404, p LT 0.01), but not between subjective and objective scores. Conclusions. Mean GHQ12 and CLDQ scores pointed out to general psychological no-distress condition of the studied participants, as well as scarcely expressed CLD-specific complaints. Mean MELD and CTP scores indicated stable chronic liver diseases, with low three-month mortality rates in the cases of chronic hepatitis, as well as determination to Child A group in the case of liver cirrhosis.",

abstract = "Metabolic syndrome (MetS) is a leading public health and clinical challenge worldwide. MetS represents a group of interrelated risk factors that predict cardiovascular diseases (CVD) and diabetes mellitus (DM). Its prevalence ranges between 10 and 84%, depending on the geographic region, urban or rural environment, individual demographic characteristics of the population studied (sex, age, racial and ethnic origin), as well as the criteria used to define MetS. Persons with MetS have higher mortality rate when compared with people without MetS, primarily caused by progressive atherosclerosis, accelerated by pro-inflammatory and pro-coagulation components of MetS. Considering the high prevalence of metabolic disorders (glucose metabolism disorder, hypertension, dyslipidaemia, obesity etc.), preventive healthcare should focus on changing lifestyle in order to reduce obesity and increase physical activity. This narrative review considers the available evidence from clinical and experimental studies dealing with MetS, and current treatment options for patients with insulin resistance and MetS.",

AB  - Subclinical hypothyroidism (SH) is characterized by a mildly elevated concentration of thyroid stimulating hormone (TSH) despite free thyroxine (FT4) and triiodothyronine (FT3) levels within the reference range. Numerous studies revealed SH to be an independent risk factor for cardiovascular disease (CVD),including atherosclerosis, congestive heart failure, coronary heart disease, ischemic heart disease and the associated mortality. The relationship between SH and CVD is well documented, but the molecular mechanism underlying this correlation remain unknown. Endothelial dysfunction has been recognized as an initial step leading to CVD in patients with SH. Changes in lipid profile, inflammation and/or oxidative stress contribute to the endothelial dysfunction in SH. Moreover, the progression of SH is characterized by significantly decreased nitrite and nitrate levels. Recent animal and clinical studies discussed in this review suggest that nitric oxide (NO) levels could be a reliable biomarker for cardiovascular risk in SH. Understanding the regulation of NO production by thyroid hormone may provide novel and useful knowledge regarding how endothelial dysfunction in SH is linked with CVD and help us to uncover new treatments for SH. We suggest that serum NO level may be an indicator for the introduction and dosage of levothyroxine (LT4) replacement therapy in SH patients. Future studies should focus on understanding the molecular mechanisms underlying the effects of NO in physiological as well as in pathophysiological conditions such as hypothyroidism and their clinical relevance.

AB  - The aim of this study was to investigate the effect of levothyroxine (LT4) replacement therapy during three months on some parameters of metabolic syndrome and atherosclerosis in patients with increased thyroid-stimulating hormone (TSH) level. This study included a group of 30 female patients with TSH level GT 4mIU/L and 15 matched healthy controls. Intima media complex thickness (IMCT) and peak systolic flow velocity (PSFV) of superficial femoral artery were determined by Color Doppler scan. In hypothyroid subjects, BMI, SBP, DBP, and TSH were significantly increased versus controls and decreased after LT4 administration. FT4 was significantly lower in hypothyroid subjects compared with controls and significantly higher by treatment. TC, Tg, HDLC, and LDL-C were similar to controls at baseline but TC and LDL-C were significantly decreased by LH4 treatment. IMCT was significantly increased versus controls at baseline and significantly reduced by treatment. PSFV was similar to controls at baseline and significantly decreased on treatment. In this study, we have demonstrated the effects of LT4 replacement therapy during three months of treatment on correction of risk factors of metabolic syndrome and atherosclerosis.

Immunity has an essential role in the regulation of glucose and lipid metabolism in the liver. Inducible nitric oxide (NO) synthase (iNOS) has been proposed as an important factor that interplays between immunity and energy metabolism and also in the pathogenesis of obesity-linked insulin resistance. In the liver, locally produced NO plays a protective role during inflammation, and the balance of NO protective and cytotoxic effects is very important. This review is focused on understanding the molecular mechanisms of iNOS regulation in the state of altered hepatic lipid metabolism, which is critical for developing new strategies for treatment of hepatic disorders.",

AB  - Non-invasive ventilation performed through an oronasal mask is a standard in clinical and homecare mechanical ventilation. Besides all its advantages, inevitable leaks through the mask cause errors in the feedback information provided by the airflow sensor and, hence, patient-ventilator asynchrony with multiple negative consequences. Here we investigate a new way to provide a trigger to the ventilator. The method is based on the measurement of rib cage movement at the onset of inspiration and during breathing by fibre-optic sensors. In a series of simultaneous measurements by a long-period fibre grating sensor and pneumotachograph we provide the statistical evidence of the 200 ms lag of the pneumo with respect the fibre-optic signal. The lag is registered consistently across three independent delay metrics. Further, we discuss exceptions from this trend and identify the needed improvements to the proposed fibre-sensing scheme.

Thus, IR may promote atherosclerosis and vascular disease in CHC patients. HCV-associated IR may also cause hepatic steatosis and resistance to antiviral treatment. In addition, HCV may contribute a direct, proatherogenetic action on the vascular wall. This review considers the impact of IR on interferon-based therapy of HCV infection and the role of insulin-sensitizing agents on the response to antiviral treatment and prevention of IR complications, including CVD.",

abstract = "Vascular smooth muscle cells (VSMC) respond to arterial wall injury by intimal proliferation and play a key role in atherogenesis by proliferating and migrating excessively in response to repeated injury, such as hypertension and atherosclerosis. In contrast, fully differentiated, quiescent VSMC allow arterial vasodilatation and vasoconstriction. Exaggerated and uncontrolled VSMC proliferation appears therefore to be a common feature of both atherosclerosis and hypertension. Signal transduction pathways in eukaryotic cells integrate diverse extracellular signals, and regulate complex biological responses such as growth, differentiation and death. One group of proline-directed Ser/Thr protein kinases, the mitogen-activated protein kinases (MAPKs), plays a central role in these signalling pathways. Much attention has focused in recent years on subfamilies of MAPKs, the extracellular signal regulated kinases (ERKs). Here we overview the work on ERKs 1 to 2, emphasising when possible their biological activities in VSMC proliferation. It is clear from numerosus studies including our own, that ERK1/ERK2 pathway has an imoprtant role in VSMC proliferation induced by insulin (INS) and thrombin. Despite the physiological and pathophysiological importance of INS and thrombin, possible signal transduction pathways involved in INS and thrombin regulation of VSMCs proliferation remains poorly understood. Thus, this review examines recent findings in signalling mechanisms involved in INS and thrombin-triggered VSMCs proliferation with particular emphasis on ERK1/2 signalling pathways. Future investigations should now focus on the mechanisms of MAPK activation which might therefore represent a new mechanism involved in the antiproliferative effect revealed in this review.",

Employing adult rat cardiomyocytes (ARC), the effects of acute (15 min) stimulation with INS (10 mIU/ml) and prolonged (2 hours and 24 hours) stimulation with E(2) alone or in combination, were assessed with respect to protein levels of Akt. Exposure to INS for 15 minutes enhanced Akt Ser(473) phosphorylation. The combined treatment had a greater effect on Akt phosphorylation then the effect of INS alone. The results suggest that INS and E(2) may interact through Akt in regulating metabolic processes.

AB  - Causal relationship between sodium and hypertension has been proposed and various changes in Na+, K+-ATPase (sodium pump) activity have been described in established primary hypertension. A number of direct vascular effects of estradiol have been reported, including its impact on the regulation of sodium pump activity and vasomotor tone. The effects of estradiol involve the activation of multiple signaling cascades, including phosphatydil inositol-3 kinase (PI3K) and p42/44 mitogen-activated protein kinase (p42/44 MAPK). In addition, some of the effects of estradiol have been linked to activity of cytosolic phospholipase A(2) (cPLA(2)). One possible cardioprotective mechanism of estradiol involves of the interaction between estradiol and the rennin-angiotensin system (RAS). Elevated circulating and tissue levels of angiotensin II (Ang II) have been implicated in the development of hypertension and heart failure. The aim of our investigation was to elucidate the signaling mechanisms employed by estradiol and Ang II in mediating sodium pump, in vascular smooth muscle cells (VSMC). The aim of our investigation was to elucidate the signaling mechanisms employed by estradiol and Ang II in mediating sodium pump activity/expression in VSMC, with particular emphasis on PI3K/cPLA(2)/p42/44(MAPK) signaling pathways. Our primary hypothesis is that estradiol stimulates sodium. pump activity/expression in VSMC via PI3K/cPLA(2)/p42/44(MAPK) dependent mechanism and, that impaired estradiol-stimulated sodium pump activity/expression in hypertensive rodent models (i.e. SHR), Ang II-mediated vascular impairment of estradiol is related to a decrease ability of estradiol to stimulate the PI3K/cPLA(2)/p42/44(MAPK) signaling pathways. An important corollary to this hypothesis is that in hypertensive state (i.e. SHR rats) the decreasing in ACE enzyme activity and/or AT1 receptor expression caused by administration of estradiol is accompanying with abrogated ability of Ang 11 to decrease IRS-1/PI3K association, and consequent PI3K/cPLA(2)/p42/44(MAPK) activity and associated sodium pump activity/expression. A clear characterization of how Ang II attenuates estradiol signaling may lead to a better understanding of the molecular mechanism(s) underlying pathophysiological conditions such as hypertension and to understanding how certain pathophysiological situations affect sodium pump activity/expression in VSMC.

AB  - Objective This study examined the sensitivity of routine abdominal ultrasound scanning in the detection of colonic malignancy. Patients and Methods A case control prospective study included 101 patients hospitalized at the Department of Gastroenterology and Liver Diseases of Zemun Clinical Hospital over a four-year period. Since the complaints pointed to colonic malignancy, the patients underwent routine golden standard diagnostic procedures. These patients were referred to an experienced abdominal ultrasound operator who searched for some characteristic signs of colonic malignancy. All of the participants were surgically treated after the completion of relevant procedures for diagnosing colonic malignancy. SPSS for Windows 10.0 was used for data analysis. Results The sensitivity of an abdominal ultrasound scan in the detection and location of pathological changes pointed to colonic malignancy was different- 76% and 84% respectively. This method was very reliable in detecting right-sided colonic carcinoma (100%). Some specific ultrasonographic signs of colonic carcinoma were observed at the advanced stages of disease. Conclusions The routine abdominal ultrasonography can be used for the screening of colonic malignancy owing to its high sensitivity, particularly in advanced disease, but solely in conjunction with other methods. Finally, abdominal ultrasonography cannot be a definitive diagnostic tool for colonic carcinoma.
