Coronary artery disease mimicking Tako-tsubo cardiomyopathy: a case report

Tako-tsubo cardiomyopathy is a syndrome mostly observed in post-menopausal women, which mimics myocardial infarction with an ST elevation; and coronary angiography shows apical ballooning but a normal left anterior descending. Although coronary artery disease is considered as an exclusion criterion, for differential diagnosis of this type of cardiomyopathy, Tako-tsubo cardiomyopathy cases accompanied by coronary artery disease were also reported. In this report, we are presenting a patient who exhibits different findings than a classical Tako-tsubo cardiomyopathy case because of her young age, coexisting atherosclerotic lesion, smaller diameter of the apical systolic ballooning and absence of an increase in cardiac enzymes

Chemotaxis systems with singular sensitivity and logistic source: Boundedness, persistence, absorbing set, and entire solutions

This paper deals with the following parabolic-elliptic chemotaxis system with singular sensitivity and logistic source, \begin{equation} \begin{cases} u_t=\Delta u-\chi\nabla\cdot (\frac{u}{v} \nabla v)+u(a(t,x)-b(t,x) u), & x\in \Omega,\cr 0=\Delta v- \mu v+ \nu u, & x\in \Omega, \cr \frac{\partial u}{\partial n}=\frac{\partial v}{\partial n}=0, & x\in\partial\Omega, \end{cases} \end{equation} where $\Omega \subset \mathbb{R}^N$ is a smooth bounded domain, $a(t,x)$ and $b(t,x)$ are positive smooth functions, and $\chi$, $\mu$ and $\nu$ are positive constants. In the very recent paper [25], we proved that for given nonnegative initial function $0\not\equiv u_0\in C^0(\bar \Omega)$ and $s\in\mathbb{R}$, (0.1) has a unique globally defined classical solution $(u(t,x;s,u_0),v(t,x;s,u_0))$ with $u(s,x;s,u_0)=u_0(x)$, provided that $a_{\inf}=\inf_{t\in\mathbb{R},x\in\Omega}a(t,x)$ is large relative to $\chi$ and $u_0$ is not small. In this paper, we further investigate qualitative properties of globally defined positive solutions of (0.1) under the assumption that $a_{\inf}$ is large relative to $\chi$ and $u_0$ is not small. Among others, we provide some concrete estimates for $\int_\Omega u^{-p}$ and $\int_\Omega u^q$ for some $p>0$ and $q>\max\{2,N\}$ and prove that any globally defined positive solution is bounded above and below eventually by some positive constants independent of its initial functions. We prove the existence of a ``rectangular'' type bounded invariant set (in $L^q$) which eventually attracts all the globally defined positive solutions. We also prove that (0.1) has a positive entire classical solution $(u^*(t,x),v^*(t,x))$, which is periodic in $t$ if $a(t,x)$ and $b(t,x)$ are periodic in $t$ and is independent of $t$ if $a(t,x)$ and $b(t,x)$ are independent of $t$

Comparison of pupillometry measurements in myopic, emmetropic and hyperopic children

To compare spherical and cylindrical equivalent, and pupillometry measurements between non-amblyopic myopic, emmetropic, and hyperopic children. The study was conducted prospectively and cross-sectionally in a single-centered eye clinic. Three non-amblyopic groups were included in the study: myopic (Myopia Group), emmetropic (Emmetropia Group), and hyperopic (Hyperopia Group) children. The groups were compared in terms of best-corrected visual acuity (BCVA), intraocular pressure (IOP), spherical equivalent (SE), and pupillometry measurements, including minimum dynamic pupillometry, maximum dynamic pupillometry, mesopic pupillometry, and photopic pupillometry. The correlation analysis was also performed between the measurements. We noted significant differences in mean SE values between the three groups and between the paired groups (p0.05 for all). The hyperopia group had the lowest mean minimum dynamic pupillometry, maximum dynamic pupillometry, mesopic pupillometry, and photopic pupillometry values (1.97±0.57, 5.23±051, 4.96±0.41, and 3.30±0.54, respectively). We found significant differences in all pupillometry measurements between the three groups (p0.05 for all). We also did not observe any correlation between the pupil diameter and age or gender (p>0.05 for both). Our study might be unique regarding the comparison of pupillometry measurements in non-amblyopic children with refractive errors. Myopia in the pediatric population may have potential pupillometric effects when compared to emmetropia and hyperopia. This should be considered in terms of the clinical relevance of pediatric refractive examination under different illumination conditions

Resilience and limitations of MFC anodic community when exposed to antibacterial agents

This study evaluates the fate of certain bactericidal agents introduced into microbial fuel cell (MFC) cascades and the response of the microbial community. We tested the response of functioning urine fed MFC cascades using two very different bactericidal agents: a common antibiotic (Ampicillin, 5 g/L) and a disinfectant (Chloroxylenol 4.8 g/L) in concentrations of up to 100 times higher than the usual dose. Results of power generation showed that the established bacteria community was able to withstand high concentrations of ampicillin with good recovery after 24 h of minor decline. However, power generation was adversely affected by the introduction of chloroxylenol, resulting in a 99% loss of power generation. Ampicillin was completely degraded within the MFC cascade (>99.99%), while chloroxylenol remained largely unaffected. Analysis of the microbial community before the addition of the bactericidal agents showed a significant bacterial diversity with at least 35 genera detected within the cascade. Microbial community analysis after ampicillin treatment showed the loss of a small number of bacterial communities and proportional fluctuations of specific strains within the individual MFCs community. On the other hand, there was a significant shift in the bacterial community after chloroxylenol treatment coupled with the loss of at least 13 bacterial genera across the cascade

THE EFFECT OF HARVESTING TIMES ON OIL AND FATTY ACID COMPOSITION OF PEANUT VARIETIES GROWN IN MAIN CROPPED CONDITION IN CUKUROVA REGION (MEDITERRANEAN AREA) IN TURKEY

This study was conducted at the experimental area of the Department of Field Crops, Faculty of Agriculture, Cukurova University as a main crop in 2015. The objective of this study was to determinate the effect of harvesting dates on oil and fatty acid composition of peanut (Arachis hypogaea L.) varieties grown in main cropped condition in Cukurova region. The experimental design was a split plot with three replications. The Halisbey, Sultan, Arioglu-2003, Osmaniye-2005, NC-7, Batem-5025, Flower 22, Flower-32, Flower-36, Brantley and Wilson peanut varieties (Virginia market type) were used as a plant material in this research. The plants were harvested at 149, 156, 163 and 170 days after sowing (DAS). Oil and fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, behenic acid and lignoceric acid) content and Oleic acid to Linoleic acid ratio (O/L) of peanut varieties were investigated. As a result, the oil percentage of peanut varieties was increased from 47.8% to 50.3% when the harvesting delayed from 149 DAS to 170 DAS. While the palmitic and linoleic acid percentage was decreasing, the stearic and oleic acid percentage was increased when the harvesting delayed from 149 DAS to 170 DAS in peanut varieties. The others fatty acids were not affected by the harvesting time
