Abstract Currently, the role of stress echocardiography primarily resides in diagnosing acquired coronary artery disease (CAD) in adults. Besides an increasing concern for traditional CAD in young patients due to obesity and other chronic pediatric diseases, there is also a growing population of adolescents and young adults with “at risk” coronary arteries due to: reimplanted coronaries in congenital heart disease, anomalous origin of the native coronary arteries, coronary abnormalities in Kawasaki’s disease, and posttransplant coronary vasculopathy. Stress echocardiography is well suited for routine screening and monitoring in these patients. Also, due to the ability of stress… More >

Abstract Objective: The aims of this study were to compare the level of posttraumatic stress disorder between adults with and without congenital heart disease, and to examine the correlates of posttraumatic stress disorder (e.g., sociodemographics).
Design: Cross-sectional.
Setting: Two university-affiliated heart hospitals in Tehran, Iran.
Patients: A sample of 347 adults with congenital heart disease aged 18–64 years (52% women), and 353 adults without congenital heart disease matched by sex and age (±2 years) was recruited. Outcome Measures: The PTSD Scale: Self-report version was used to assess the diagnosis and severity of posttraumatic stress disorder. Hierarchical multivariate logistic regression analyses… More >

Abstract Background: Stent implantation is the treatment of choice for adolescents and adults with aortic coarctation (CoAo). Despite excellent short-term results, 20%–40% of the patients develop arterial hypertension later in life, which was attributed to inappropriate response of the aortic baroreceptors to increased stiffness of the ascending aorta (ASAO), either congenital or induced by CoAo repair. In particular, it has been hypothesized that stent itself may cause or sustain hypertension. Therefore, we aimed to study the hemodynamic and structural impact following stent implantation in the normal aorta of a growing animal.
Methods: Eight female sheep completed the study… More >

Abstract The development of flax fiber reinforced polymer composites with improved properties has been increasingly studied by many researchers because of their sustainability. However, the effects of thermal residual stresses on the interfacial properties of flax composites have not been evaluated or very well understood. In this study, the thermal properties of flax, vinyl ester matrices and their composites were accessed by different techniques, including thermomechanical analyzer, dynamic mechanical analyzer, and X-ray diffraction combined with aluminum particles. The effects of thermal properties of flax fibers and vinyl ester resin systems on the mechanical properties of their More >

Abstract Understanding the genetic control of traits associated with yield helps breeders to utilize their germplasm in a more efficient and consistent manner and to make good choices in breeding programs. The current study was carried out to study the genetic control of some quantitative traits in bread wheat (Triticum aestivum L.) and to examine plant responses under full irrigation and drought stress conditions. For this purpose, six generations derived from a cross between two lines (Bezostaya as tolerant parent and 518 as a susceptible parent) were evaluated for grain yield (GY), plant height (PH), peduncle (PL)… More >

Abstract The mixed salt stress is common in nature. Salt stress always affects plant growth. Different plant species have different adaptive capacity to salty soils. Leymus chinensis is an herbaceous plant with different leaf colors. However, little research was conducted to explore the different tolerance mechanisms to salt stress among the three different leaf colour genotypes of Leymus chinensis (grey green, transitional color, yellow green). Pot experiments for Leymus chinensis in three leaf colors were conducted under mixed salt treatments in 2010. Malondialdehyde (MDA) and protein concentrations, and the activity of various antioxidant enzymes [i.e., superoxide dismutase (SOD), catalase… More >

Abstract Among the different types of abiotic stresses, water is the most damaging for crops. In the current research, the effect of water stress, induced with Polyethylene Glycol 8000 (PEG8000) and Sodium chloride (NaCl) solutions, was studied in maize genotypes. A randomized block design (RBD) with a factorial arrangement and four replications of 25 seeds each was used. The studied maize genotypes were RC₂C39, RC₂C51 (wild varieties of the State of Tabasco backcrossed with the endogamic line CML247 of the International Center for the Improvement of Maize and Wheat), wild Tamulte, VS536, and Asgrow 7573 hybrid, study… More >

Abstract It is documented that vermicompost increases germination and productivity of crops, but little is known of its effect on plant physiological responses under soil water deficit. The aim of this study was to analyze the effect of vermicompost and irrigation interruption on stomatal conductance, gas exchange, and yield of common bean cultivars (drought tolerant -cv. 92 and drought susceptible-cv. 122). Plants were cultivated in unamended soil or soil amended with 1.5 and 3% of vermicompost, with irrigation during the whole cycle but irrigation interruption at the flowering stage. Changes in soil moisture, stomatal conductance (g_s), transpiration… More >

Abstract Focal adhesion kinase (FAK) plays a vital role in mediating the adaptability of tumor cells under mechanical stimuli. Previous studies revealed that FAK can locate to different cell compartments, and its regulation is highly dependent on its subcellular localization. However, the local FAK activities and its regulation mechanism in different cell compartments of tumor cells in response to fluid shear stress are still unclear. In this study, 5 dyn/cm² and 20 dyn/cm² of shear stress was applied to HeLa cells for 30 min. The activities of FAK targeting different subcellular compartments (lipids rafts, non-rafts, focal adhesions… More >

Abstract Coronary tortuosity is a common angiographic finding, but the hemodynamic significance of coronary tortuosity is largely unknown. The impact of coronary tortuosity on coronary pressure and wall shear stress is still unclear. We addressed this issue in the present experimental study. A distorted tube model connected to heart pumping machine was established to simulate the coronary circulation. The pressure of each point was measured with a coronary pressure guidewire. Influence of tortuosity angle and tortuosity number on local pressure was measured. Wall shear stress was calculated accordingly to the pressure of each point. Pressure distribution… More >
