Abstract
OBJECTIVES Cardiac surgery for coronary artery disease was dramatically reduced during the first wave of the COVID-19 pandemic. Many patients with disease ordinarily treated with coronary artery bypass grafting (CABG) instead underwent percutaneous coronary intervention (PCI). We sought to describe 12-month outcomes following PCI in patients who would typically have undergone CABG. METHODS Between March 1 and July 31, 2020, patients who received revascularization with PCI when CABG would have been the primary choice of revascularization were enrolled in the prospective, multicenter UK-ReVasc Registry. We evaluated the following major adverse cardiovascular events at 12 months: all-cause mortality, myocardial infarction, repeat revascularization, stroke, major bleeding, and stent thrombosis. RESULTS A total of 215 patients were enrolled across 45 PCI centers in the United Kingdom. Twelve-month follow up data were obtained for 97% of the cases. There were 9 deaths (4.3%), 5 myocardial infarctions (2.4%), 12 repeat revascularizations (5.7%), 1 stroke (0.5%), 3 major bleeds (1.4%), and no cases of stent thrombosis. No difference in the primary endpoint was observed between patients who received complete vs incomplete revascularization (residual SYNTAX score £ 8 vs > 8) (P = .22). CONCLUSIONS In patients with patterns of coronary disease in whom CABG would have been the primary therapeutic choice outside of the pandemic, PCI was associated with acceptable outcomes at 12 months of follow-up. Contemporary randomized trials that compare PCI to CABG in such patient cohorts may be warranted.

Abstract
Background Thyroid pathologies are very common diseases. The most common thyroid pathologies are goiter and thyroid nodules. Thyroid ultrasonography is the most widely used examination method in the evaluation of thyroid pathologies. The aim of this field study is to determine the frequency of thyroid pathologies in the province of Tokat and to evaluate its relationship with some factors such as gender and dietary habits. Materials and Methods In this population-based prospective study, thyroid US examination was performed on a total of 822 patients. The examination procedure was carried out by one radiologist with at least 10 years of experience. During the examination, thyroid dimensions, parenchyma echo, presence of nodule, echo if any, number, size, and localization were evaluated. The relationships between thyroid pathologies and age, gender, body mass index (BMI), and chronic diseases in the participants were evaluated. Results Up to 45.2% (n = 372) of the participants were male and 54.8% (n = 417) were female. The ages of the participants ranged from 20 to 87 years. The mean age of the participants was 47.2. Up to 9.8% of the participants had an increase in thyroid size, defined as goiter. Parenchyma was homogeneous in 72.1% of the participants and heterogeneous in 27.9%. Thyroid nodules were present in the thyroid gland in 40.8% of the participants. There was a statistically significant relationship between thyroid pathologies and female gender, age, and obesity. Conclusion Thyroid diseases show regional differences. Older age, female gender, and obesity increase the frequency of thyroid pathologies.

Abstract
OBJECTIVES The purpose of this study was to investigate the effectiveness of Kinesio® tape application associated to exercise in patients with obstetric brachial plexus injury (OBPI). MATERIALS AND METHODS Ninety patients with Erb-Duchenne palsy secondary to OBPI participated in a 3-month study, in 2 groups; study group (n = 50) and control group (n = 40). Both followed the same physical therapy program, while the study group also received Kinesio® taping over the scapula and forearm. The patients were evaluated, pre- and post-treatment, using the Modified Mallet Classification (MMC), Active Movement Scale (AMS), and active range of motion (ROM) of the plegic side. RESULTS There were no statistically significant intergroup differences in age, gender, birth weight or plegic side (p > 0.05), or in pre-treatment MMC and AMS scores (p > 0.05). There were significant differences in favor of the study group for Mallet 2 (external rotation) (p = 0.012), Mallet 3 (hand on the back of the neck) (p < 0.001), Mallet 4 (hand on the back) (p = 0.001) and total Mallet score (p = 0.025), and for AMS shoulder flexion (p = 0.004) and elbow flexion (p < 0.001). ROM results before and after treatment (within groups) showed significant improvement in both groups (p < 0.001). CONCLUSION Since this a was a preliminary study, the results should be interpreted with caution in terms of clinical efficacy. The results suggest that associating Kinesio® taping to conventional treatment helps functional development in patients with OBPI.'

Abstract
Abstract
Background
Invasive coronary angiography and non-invasive viability testing are the cornerstones of diagnosing and managing ischemic left ventricular dysfunction. At present there is no single test which serves both needs but, if developed, could revolutionise investigation of this condition. Coronary wave intensity analysis (cWIA) interrogates both contractility and microvascular physiology of the subtended myocardium [1,2] and therefore has the potential to fulfil this goal.
Objectives
We hypothesized that cWIA measured during coronary angiography would predict functional recovery with a similar accuracy to late gadolinium enhanced cardiac magnetic resonance imaging (LGE-CMR).
Methods
Patients with a left ventricular ejection fraction ≤40% and extensive coronary disease were enrolled. cWIA, fractional flow reserve and microvascular resistance were assessed with a simultaneous coronary Doppler and pressure-sensing guidewire during cardiac catheterization at rest, during hyperaemia and during low-dose dobutamine stress. Viability was assessed using LGE-CMR. Regional left ventricular function was assessed at baseline and 6-month follow up after optimization of medical therapy +/− revascularization, using transthoracic echocardiography. The primary outcome was regional functional recovery.
Results
Forty participants underwent baseline physiology, LGE-CMR and thirty had echocardiography at baseline and 6 months; 21/42 territories demonstrated functional recovery. Resting backward compression wave energy was significantly greater in recovering than non-recovering territories (−5240±3772 vs. −1873±1605 W m–2 s–1, p=0.099, Figure 1), and had comparable diagnostic accuracy to CMR (area under the curve 0.812 vs. 0.757, p=0.649, Figure 2); a threshold of −2500 W mm–2 s–1 had 86% sensitivity and 76% specificity at predicting recovery. Backward expansion wave energy did not predict recovery. FFR was numerically higher in recovering territories (0.81±0.17 vs. 0.71±0.16, p=0.058), whilst hyperaemic microvascular resistance did not differentiate recovering from non-recovering territories (1.97±0.73 vs. 2.29±1.00, p=0.287). The likelihood of functional recovery was similar in revascularised and non-revascularised territories (15/29 vs. 6/13 respectively, p=0.739). Low-dose dobutamine stress increased the energy of all waves, but did not improve the accuracy of cWIA in predicting recovery. In a regression model, resting backward compression wave energy and optimization of medical therapy predicted functional recovery; fractional flow reserve and hyperemic microvascular resistance did not.
Conclusions
Backward compression wave energy has similar accuracy to LGE-CMR in the prediction of functional recovery. cWIA has the potential to revolutionise the management of ischaemic left ventricular dysfunction, in a manner analogous to the effect of fractional flow reserve on the management of stable angina.

Abstract
The COVID-19 pandemic severely impacted all facets of daily life, including and especially mobility within urban centres. As part of efforts to control the virus by encouraging citizens to stay at home, local governments imposed public health and social measures (PHSMs) restricting the availability and use of public transit. The result was an immediate, sharp decline in the use of public transit, and later as the pandemic was brought under control in certain geographies, a reluctance to return to using public transportation due to sustained fears of virus transmission. In Istanbul, Turkey, the use of public transportation decreased by over 90%, coupled with a significant rise in the use of private motorised transportation. To counter this trend, the Istanbul Metropolitan Municipality (IMM) joined cities around the world in implementing a two-pronged strategy to support safe and active mobility during the pandemic. IMM first launched a communication campaign to promote adherence to PHSMs, to rebuild trust in the safety of public transportation as restrictions eased, and to educate citizens on transportation alternatives. Billboards, social media and digital screens on public transportation promoted continued mask use, hand-washing and physical distancing and encouraged citizens wary of returning to public transit to consider walking or cycling as a safe and healthy alternative to private car use. IMM simultaneously enhanced their cycling infrastructure, creating new temporary and permanent bike lanes that closed connectivity gaps within the city. This talk will further elaborate on IMM's actions and the results and explore how they and other cities can sustain the focus on safe and active mobility as a longer-term strategy to reduce private car use and improve health outcomes.

Abstract
Presence of heart failure is associated with a poor prognosis in patients with coronavirus disease 2019 (COVID-19). The aim of the present study was to examine whether first-phase ejection fraction (EF1), the ejection fraction measured in early systole up to the time of peak aortic velocity, a sensitive measure of preclinical heart failure, is associated with survival in patients hospitalized with COVID-19. A retrospective outcome study was performed in patients hospitalized with COVID-19 who underwent echocardiography (n=380) at the West Branch of the Union Hospital, Wuhan, China and in patients admitted to King's Health Partners in South London, United Kingdom. Association of EF1 with survival was performed using Cox proportional hazards regression. EF1 was compared in patients with COVID-19 and in historical controls with similar comorbidities (n=266) who had undergone echocardiography before the COVID-19 pandemic. In patients with COVID-19, EF1 was a strong predictor of survival in each patient group (Wuhan and London). In the combined group, EF1 was a stronger predictor of survival than other clinical, laboratory, and echocardiographic characteristics including age, comorbidities, and biochemical markers. A cutoff value of 25% for EF1 gave a hazard ratio of 5.23 ([95% CI, 2.85-9.60]; P<0.001) unadjusted and 4.83 ([95% CI, 2.35-9.95], P<0.001) when adjusted for demographics, comorbidities, hs-cTnI (high-sensitive cardiac troponin), and CRP (C-reactive protein). EF1 was similar in patients with and without COVID-19 (23.2±7.3 versus 22.0±7.6%, P=0.092, adjusted for prevalence of risk factors and comorbidities). Impaired EF1 is strongly associated with mortality in COVID-19 and probably reflects preexisting, preclinical heart failure.

Abstract
OBJECTIVE To evaluate the impact of left ventricular outflow tract calcification (LVOT-CA) localization and extension on permanent pacemaker implantation (PPI) rates after transcatheter aortic valve implantation (TAVI) with second-generation devices. METHODS This single-center retrospective study included all consecutive patients who underwent transfemoral TAVI with second-generation devices at San Raffaele Hospital in Milan, Italy from January 2014 to June 2017. The localization and extension of LVOT-CA were evaluated using computed tomography imaging; LVOT regions were categorized according to the overlying coronary cusps. RESULTS The study population consisted of 377 patients, of which LVOT-CA was present in 133 patients (35.3%). Patients with LVOT-CA had significantly a higher rate of post-TAVI PPI (32.0% vs 19.2% in patients with no LVOT-CA; P<.01). Multivariable analysis demonstrated LVOT-CA in the non-coronary cusp, as well as preprocedural right bundle-branch block, age, body mass index, and mechanically expanded prosthesis implantation, to be strong independent predictors of PPI. CONCLUSIONS LVOT-CA in the non-coronary cusp is a strong independent predictor of PPI after TAVI with second-generation devices. Further studies are needed to confirm these data in a larger, multicenter population.

Abstract
OBJECTIVES In this study, a systematic analysis was conducted of phasic intracoronary pressure and flow velocity in patients with severe aortic stenosis (AS) and coronary artery disease, undergoing transcatheter aortic valve replacement (TAVR), to determine how AS affects: 1) phasic coronary flow; 2) hyperemic coronary flow; and 3) the most common clinically used indices of coronary stenosis severity, instantaneous wave-free ratio and fractional flow reserve. BACKGROUND A significant proportion of patients with severe aortic stenosis (AS) have concomitant coronary artery disease. The effect of the valve on coronary pressure, flow, and the established invasive clinical indices of stenosis severity have not been studied. METHODS Twenty-eight patients (30 lesions, 50.0% men, mean age 82.1 ± 6.5 years) with severe AS and coronary artery disease were included. Intracoronary pressure and flow assessments were performed at rest and during hyperemia immediately before and after TAVR. RESULTS Flow during the wave-free period of diastole did not change post-TAVR (29.78 ± 14.9 cm/s vs. 30.81 ± 19.6 cm/s; p = 0.64). Whole-cycle hyperemic flow increased significantly post-TAVR (33.44 ± 13.4 cm/s pre-TAVR vs. 40.33 ± 17.4 cm/s post-TAVR; p = 0.006); this was secondary to significant increases in systolic hyperemic flow post-TAVR (27.67 ± 12.1 cm/s pre-TAVR vs. 34.15 ± 17.5 cm/s post-TAVR; p = 0.02). Instantaneous wave-free ratio values did not change post-TAVR (0.88 ± 0.09 pre-TAVR vs. 0.88 ± 0.09 post-TAVR; p = 0.73), whereas fractional flow reserve decreased significantly post-TAVR (0.87 ± 0.08 pre-TAVR vs. 0.85 ± 0.09 post-TAVR; p = 0.001). CONCLUSIONS Systolic and hyperemic coronary flow increased significantly post-TAVR; consequently, hyperemic indices that include systole underestimated coronary stenosis severity in patients with severe AS. Flow during the wave-free period of diastole did not change post-TAVR, suggesting that indices calculated during this period are not vulnerable to the confounding effect of the stenotic aortic valve.

Abstract
Tricuspid valve regurgitation has a high prevalence and, when severe, is associated with poor outcomes. Nevertheless, surgical repair or replacement (isolated or as a part of a combined procedure) is rarely performed due to high surgical risk. Therefore, there is a significant unmet clinical need for percutaneous transcatheter-based treatments. Significant development in percutaneous therapies for both aortic and mitral valve disease has been accomplished over the last two decades, while transcatheter therapies for the tricuspid valve are still at an early stage. We are today at a cross-road of new transcatheter devices that are becoming available for the treatment of tricuspid regurgitation; the current review evaluates the challenges that current and future technologies have to face in order to become a safer, less invasive and equally effective alternative to surgery.

Abstract
Transcatheter aortic valve implantation (TAVI) is a worldwide accepted alternative for treating patients at intermediate or high risk for surgery. In recent years, the rate of complications has markedly decreased except for new-onset atrioventricular and intraventricular conduction block that remains the most common complication after TAVI. Although procedural, clinical, and electrocardiographic predisposing factors have been identified as predictors of conduction disturbances, new strategies are needed to avoid such complications, particularly in the current TAVI era that is moving quickly toward the percutaneous treatment of low-risk patients. In this article, we will review the incidence, predictive factors, and clinical implications of conduction disturbances after TAVI.

Abstract
Aims The efficacy of patent foramen ovale (PFO) closure for cryptogenic stroke has been controversial. We undertook a meta-analysis of randomized controlled trials (RCTs) comparing device closure with medical therapy to prevent recurrent stroke for patients with PFO. Methods and results We systematically identified all RCTs comparing device closure to medical therapy for cryptogenic stroke in patients with PFO. The primary efficacy endpoint was recurrent stroke, analysed on an intention-to-treat basis. The primary safety endpoint was new onset atrial fibrillation (AF). Five studies (3440 patients) were included. In all, 1829 patients were randomized to device closure and 1611 to medical therapy. Across all patients, PFO closure was superior to medical therapy for prevention of stroke [hazard ratio (HR) 0.32, 95% confidence interval (95% CI) 0.13-0.82; P = 0.018, I2 = 73.4%]. The risk of AF was significantly increased with device closure [risk ratio (RR) 4.68, 95% CI 2.19-10.00, P<0.001, heterogeneity I2 = 27.5%)]. In patients with large shunts, PFO closure was associated with a significant reduction in stroke (HR 0.33, 95% CI 0.16-0.72; P = 0.005), whilst there was no significant reduction in stroke in patients with a small shunt (HR 0.90, 95% CI 0.50-1.60; P = 0.712). There was no effect from the presence or absence of an atrial septal aneurysm on outcomes (P = 0.994). Conclusion In selected patients with cryptogenic stroke, PFO closure is superior to medical therapy for the prevention of further stroke: this is particularly true for patients with moderate-to-large shunts. Guidelines should be updated to reflect this.

Abstract
Objective International guidelines recommend the use of dual antiplatelet therapy (DAPT) after transcatheter aortic valve implantation (TAVI). The recommended duration of DAPT varies between guidelines. In this two-part study, we (1) performed a structured survey of 45 TAVI centres from around the world to determine if there is consensus among clinicians regarding antiplatelet therapy after TAVI; and then (2) performed a systematic review of all suitable studies (randomised controlled trials (RCTs) and registries) to determine if aspirin monotherapy can be used instead of DAPT. Methods A structured electronic survey regarding antiplatelet use after TAVI was completed by 45 TAVI centres across Europe, Australasia and the USA. A systematic review of TAVI RCTs and registries was then performed comparing DAPT duration and incidence of stroke, bleeding and death. A variance weighted least squared metaregression was then performed to determine the relationship of antiplatelet therapy and adverse events. Results 82.2% of centres routinely used DAPT after TAVI. Median duration was 3 months. 13.3% based their practice on guidelines. 11 781 patients (26 studies) were eligible for the metaregression. There was no benefit of DAPT over aspirin monotherapy for stroke (P=0.49), death (P=0.72) or bleeding (P=0.91). Discussion Aspirin monotherapy appears to be as safe and effective as DAPT after TAVI.

Abstract
Various factors are involved in the aetiology of premature ejaculation (PE). Hyperthyroidism is one of the causes of acquired PE, but the exact mechanism by which it causes the disorder is not yet understood. The aim of this study was to evaluate the role of the dopaminergic system in hyperthyroidism-induced PE by the intracerebroventricular microinjection of the preferentially active dopamine receptor agonist 7-hydroxy-2-(di-N-propylamino) tetralin (7-OH-DPAT) in a rat model of this disorder. Wistar rats were randomly divided into hyperthyroid and control groups, and ejaculation was induced by the ICV administration of 7-OH-DPAT. To evaluate the emission and expulsion phases of ejaculation, measurements of seminal vesicle pressure (SVP) and electromyographic recordings of the bulbospongiosus muscle were taken. The interval between the 7-OH-DPAT administration and the first ejaculation was significantly less in the hyperthyroid group (p < .01) than in the control group, and the maximum amplitude of the SVP values revealed a statistically significant difference between the groups (p < .01). The intervals between contractions of the seminal vesicle and bulbospongiosus muscles were also significantly less in the hyperthyroid group (p = .0187) than in the control group. No other results differed significantly between the groups. This study determined that hyperthyroidism altered only the emission phase of ejaculation.

Abstract
The aim of this study was to describe our experience with treating Dupuytren's disease using needle aponeurotomy and non-centrifuged autologous fat grafting. The study included 17 patients (18 hands). Patients were treated with needle aponeurotomy and non-centrifuged autologous fat graft under general anesthesia. The fat grafts were injected into the surgical area so as to stay in contact with the operated site. An extension splint was used for 1 week postoperatively and the patients received hand therapy for 3 weeks. Before the treatment, the contracture in the proximal interphalangeal and metacarpophalangeal joints was a mean of 45.06 ± 13.44 degrees and 36.56 ± 13.09 degrees, respectively. It was 1.61 ± 1.65 and -0.56 ± 3.78 degrees at 3 months, respectively. The difference between these measurements was statistically significant. The mean follow-up period was 12 months. The results were satisfactory and no complications were observed during the follow-up period. Based on the results of the study, percutaneous aponeurotomy with non-centrifuged autologous fat grafting was found to have significantly beneficial effects in the treatment of Dupuytren's disease.

Abstract
INTRODUCTION The risk of kidney stone formation increases with urinary stasis, which is associated with decreased peristaltism. The relationship between nonobstructive kidney stone formation and ureteral jet dynamics, which can be measured with Doppler ultrasonography (US) and provide information about ureteral peristaltism, has been demonstrated in adults. OBJECTIVE To investigate the relationship between ureteral jet dynamics, which provide information about ureteral peristaltism, and stone formation in children. STUDY DESIGN Children admitted to Dokuz Eylul University Hospital with flank pain, and asymptomatic age-matched children for the control group, were prospectively enrolled and underwent Doppler US for diagnostic reasons and bilateral ureteral jet flow measurements. Children diagnosed with unilateral nonobstructive lower pole kidney stones formed Group 1, and the control group, without any evidence of stone disease, formed Group 2. Ureteral jet dynamics were compared between the affected renal units in Group 1, and healthy renal units in Group 1 and Group 2. RESULTS A total of 32 children were included for each group. The mean average jet flow-rate (JETave (cm/second)) in affected renal units in Group 1 was found to be significantly lower than in the healthy renal units in Group 1 and left and right healthy renal units in Group 2 (P < 0.05). The continuous JETpattern rate in affected renal units in Group 1 was found to be significantly higher compared with healthy renal units in Groups 1 and 2 (P = 0.012) (Table). The odds ratio for kidney stone formation was 5.6 for renal units with JETave <9.5 cm/s when compared with renal units with JETave ≥9.5 cm/s. DISCUSSION In a recent study, it was demonstrated in adults that low ureteral jet flow-rate and continuous JETpattern were significantly higher in affected renal units. The findings in children were also similar to adults: the mean JETave was significantly lower and determination rate of continuous flow pattern was significantly higher in affected renal units. CONCLUSIONS Children with low JETave and continuous JETpattern as a sign of decreased ureteral peristaltism are at an increased risk of kidney stone formation. However, it is vital that further studies are conducted to elaborate on this topic.

Abstract
OBJECTIVES This study investigated whether Dexpanthenol (DEX) improves diabetic cardiovascular function and cardiac performance by regulating total oxidant and antioxidant status. METHODS Diabetes was induced by a single intraperitoneal injection of Streptozocin (50 mg/kg in 1 ml of saline) and treatment groups received DEX (300 mg/kg/day) for 6 weeks. Endothelium (in)dependent relaxation responses were assessed in thoracic aortic rings and coronary vasculature together with alpha receptor and voltage dependant contractile responses of aorta. Myocardial contractility has been recorded by an intra ventricular latex balloon. Total oxidant and antioxidant status were measured from the serum samples. RESULTS Induction of diabetes resulted in an apparent body weight loss, high blood glucose, endothelial dysfunction and increased serum oxidant status. DEX supplementation restored the endothelial dysfunction, antioxidant status and body weight whereas decreasing blood glucose level. CONCLUSION Along with the standard therapy of diabetes, DEX can be used as a safe and economical way of adjuvant therapy to diminish the burden of the disease (Tab. 3, Fig. 3, Ref. 30).

Abstract
AIM Peripheral arterial disease (PAD) is a less known condition in the practice of internal medicine, mostly due to lack of specific symptoms and low rates of physician awareness. However, cardiovascular disease (CVD) incidence is not significantly different among patients with symptomatic or asymptomatic disease. Ankle brachial index (ABI) measurement is an easy and cost-effective tool for the diagnosis of PAD. In the present study, frequency of low ABI and associated factors were investigated in the setting of internal medicine practice. METHODS Patients over 70 years of age and patients between 50 and 69 years with CVD or at least one atherothrombosis risk factor were included in the study. ABI was determined with handheld Doppler. Measurements were determined for both lower extremities. Lower of the right or left ABIs was taken as the final value. Low ABI was defined as ≤0.9. RESULTS A total of 303 subjects between 50 and 83 years of age were enrolled (female/male: 186/117). Mean ABI was 1.14±0.15. A low ABI was detected in 15 cases (4.95%). Prevalence was 7% in females and 1.7% in males (P=0.039). Low ABI value was not associated with any of the demographic parameters, presence of major risk factors or basic laboratory values. A high ABI was found by 5.6%. CONCLUSION In the present study, frequency of PAD as determined by ABI was found lower than those reported previously in most European countries. Nonetheless, our results showed that PAD affects at least 1 in 20 outpatients in the practice of internal medicine.

Abstract
PURPOSE To observe the outcome of maximal transurethral resection of bladder tumor (TURBT) followed by induction chemotherapy and concurrent chemoradiotherapy in medically inoperable patients with bladder cancer. METHODS This study included 30 patients with stage T 2-4 bladder cancer. The patients were first treated with TURBT, and then received 2 cycles of induction chemotherapy with gemcitabine and cisplatin, followed by concurrent chemoradiotherapy with gemcitabine. RESULTS Median follow up was 28.9 months. Radiologically, complete and partial response rates were 60 and 36.7%, while cystoscopically they were 40 and 30%, respectively. Local progression (4 cases) and distant metastasis (11 cases) were noted. Median overall survival and progressionfree survival were 32 and 21 months, respectively. One -and 2-year overall survival and progression-free survival rates were 97.60% and 83.49%, respectively. CONCLUSION The multimodal treatment performed in this study was well tolerated and achieved a high rate of bladder preservation in selected patients with bladder cancer.

The aim of this study is to evaluate the effects of hypercholesterolemia in thoracic aorta (TA), mesenteric artery (MA), renal artery (RA), and corpus cavernosum (CC) isolated from cholesterol-fed rabbits. For determination of the maximum detrimental effect, vasorelaxation and vasoconstriction results of arteries and CC have been compared. Animals were fed with a diet that contained 2% w/w cholesterol and 2% w/w high cholesterol plus resveratrol (4 mg kg(-1) per day) for 6-week duration. Total cholesterol levels in the plasma were measured. Vascular and endothelial functions in RA, TA, MA, and CC were assessed by isolated tissue bath with cumulative doses of acetylcholine and sodium nitroprusside. The statistical significance of differences of groups was analyzed by means of one-way ANOVA or Student's t-test. P-values <0.05 were considered significant. There have been no significant changes on plasma total cholesterol levels between cholesterol and cholesterol + resveratrol-treated groups. Vasorelaxation responses to acetylcholine in resveratrol-treated group showed significant changes when compared with hypercholesterolemic group. No statistically significant differences were seen between non-receptor-mediated vasorelaxation responses between the three groups. Resveratrol might be an effective treatment in the prevention of atherosclerotic changes in arteries and CC. The initial effects of hypercholesterolemia on erectile dysfunction and endothelial dysfunction may be precluded with resveratrol. This protective effect may also ensure the prevention of coronary arterial diseases and renovascular diseases in hypercholesterolemic patients.

Abstract
Various natural hazards such as landslides, avalanches, floods and debris flows can result in enormous property damages and human casualties in Eastern Black Sea region of Turkey. Mountainous topographic character and high frequency of heavy rain are the main factors for landslide occurrence in Ardesen, Rize. For this reason, the main target of the present study is to evaluate the landslide hazards using a sequence of historical aerial photographs in Ardesen (Rize), Turkey, by Photogrammetry and Geographical Information System (GIS). Landslide locations in the study area were identified by interpretation of aerial photographs dated in 1973 and 2002, and by field surveys. In the study, the selected factors conditioning landslides are lithology, slope gradient, slope aspect, vegetation cover, land class, climate, rainfall and proximity to roads. These factors were considered as effective on the occurrence of landslides. The areas under landslide threat were analyzed and mapped considering the landslide conditioning factors. Some of the conditioning factors were investigated and estimated by employing visual interpretation of aerial photos and topographic data. The results showed that the slope, lithology, terrain roughness, proximity to roads, and the cover type played important roles on landslide occurrence. The results also showed that degree of landslides was affected by the number of houses constructed in the region. As a consequence, the method employed in the study provides important benefits for landslide hazard mitigation efforts, because a combination of both photogrammetric techniques and GIS is presented.

Abstract
Coal workers’ pneumoconiosis (CWP) is an occupational pulmonary disease that occurs by chronic inhalation of coal dust. CWP is divided into two stages depending on the extent of the disease, as simple pneumoconiosis (SP) and progressive massive fibrosis (PMF). In the present study, serum and bronchoalveolar lavage (BAL) cytokine (interleukin-1β [IL-1β], IL-6, tumor necrosis factor-α [TNF-α], transforming growth factor-β [TGF-β]) and antioxidant enzymes levels, their relation with the disease severity, and whether they can be considered as biological markers were investigated. Serum and BAL levels of IL-1β, IL-6, and TNF-α were higher in SP and PMF patient groups compared with that in active and retired miner groups. Serum and BAL IL-1β, IL-6, and TNF-α levels were also found to be higher in patients with PMF compared with the SP group. BAL superoxide dismutase (SOD), glutathione peroxidase, and catalase levels and serum SOD level were increased in both patient groups compared with the control group. In addition, mean serum and BAL TGF-β levels were found to be increased in patients with SP compared with PMF group. Based on these results, BAL and serum cytokine and antioxidant enzymes levels were evaluated and discussed as potential biomarkers for different stages of CWP.
