Aim: To assess the shape of the nasopalatine canal in the sagittal plane, coronal plane and axial plane. To assess the length of the nasopalatine canal in the sagittal plane and to assess the Influence of age and gender on these parameters of nasopalatine canal.
 Methodology: A sample of 90 subjects were taken. Shape of nasopalatine canal in sagittal plane is assessed in males and females and all the age groups and classified as cylindrical, funnel, hourglass and spindle shape. The shape of the NPC in the coronal plane is classified according to Bornstein as Single (type A), double (type B), Y shaped (type C). The shape of the NPC at the mid-level was assessed in the axial plane and classified as oval, round, heart and triangular shape. The length of the nasopalatine canal is measured in the sagittal plane.
 Results: The results showed cylindrical shape was most common in sagittal plane which showed statistical significance. Results showed males have significant longer canals than females. In coronal plane, Y shape was prevalent, but no significant results were observed. In the axial plane, in males and females was heart shape and round shape were prevalent respectively. In the axial plane, the most common shape of NPC was heart shape in group I and group III, round shape in group II. No statistically significant results observed.
 Conclusion: The present study concluded there were significant morphological variations of NPC in males and females in different age groups. These morphological variations may cause complications during different treatment procedures. Assessment of the NPC using CBCT helps in implant rehabilitation and surgical treatment planning.

Can memory color effects be explained by cognitive penetration?

ABSTRACT Orange heart shapes are commonly perceived as slightly reddish, which is an example of the memory color effect (MCE). Given that the MCE is a modulation of visual memories of typical colors of familiar objects, it can be considered to be a top-down effect. Whether cognitive penetration can explain MCEs has been actively debated since Macpherson argued that the belief that hearts are red alters orange perception. This paper aims to provide a credible explanation of the MCE that is consistent with scientific studies. I first prove that Macpherson’s theory is not properly supported by the psychological evidence that she provides. I also show that her model contradicts a report on the neural correlate of the MCE. Next, I examine color constancy, which enables the perception of colors as constant under various illuminations, as a possible noncognitive principle for the MCE. The relationship between them, however, is not well established. Using statistical analyses of scenes around us, Purves suggests that perception is determined by the most frequent percepts. I argue that Purves’ view better explains the noncognitive aspects of visual memory and is consistent with the finding of the neural correlate of the MCE.

String Sign and Heart Shape After 34-mm Evolut R Valve Implantation.

An 83-year-old gentleman underwent transcatheter aortic valve replacement using a 34-mm Evolut R valve. Considering the residual mean gradient (19 mmHg) and the presence of the string sign, post-dilatation was performed. The infolding persisted on fluoroscopy but the final mean gradient was 9 mmHg. At 30-day follow-up, transeosophageal echocardiography and CT scan showed a heart-shaped prosthesis inflow. Follow-up at 3 years did not show any sign of early structural valve deterioration.

Narrative Polyphony of Sting’s Album “Ten Summoner’s Tales” (1993)

The article analyses the specifications of narrative structures and types of narrators in the song lyrics from the album “Ten Summoner’s Tales” (1993), based on “Canterbury Tales” by Geoffrey Chaucer and traditionally claimed the Magnum Opus of Sting. Apparently, Chaucerian style in all the twelve verses composing the album emerges not merely as the interpretation of original “Canterbury Tales” plots or impartment of the new features to the initial characters, but predominantly as exploitation of the lyrical and ironic intonations within an image of a narrator for a certain poem. Since a song is the synthetic generic structure marked with profound internal experience, Sting’s album reveals the diverse types of a speaker in every verse. Primarily, it is the ‘I-narrator’ embodied in poetic masks of a historian, a warrior, a saint, a gambler or a philosopher; some texts like “Fields of Gold” or “Shape of My Heart” represent the alternation of speaker types, which method of storytelling creates the special generic and narrative polyphony for a song. Subsequently, the narrative structure would determine the genre of a separate work: a detective story, a pastoral, a historical reflection, a cumulative tale, a confession, and somehow a Dante-styled epic poem. Overall, the various types of narrators in Sting’s lyrics composing “Ten Summoner’s Tales” (determined as ‘reflexive,’ ‘actor,’ ‘pointillist’ and ‘medium’ with all possible combinations) bring the elements of the author’s own vital and creative experience into the song where they gain the generalized meanings as symbols of human life, being surrounded with verbal images and amplified with musical accompaniment.

Takotsubo cardiomyopathy – review of current literature

Takotsubo syndrome (TTS) also known as broken heart syndrome is acute cardiac disease, which is characterized by reversible ventricular motion abnormalities, in the absence of justifying coronary artery disease. The clinical entity was first described in Japan in 1991. The word “Takotsubo” is a container used by the Japanese to catch octopus, which has a narrow neck and a relatively wide base, which resembles the heart's shape in TTS. The cardiomiopathy predominantly affects postmenopausal women and is often preceded by emotional (death of close family member, domestic abuse) or physical (external injury, severe pain) stress. The exact pathophysiological mechanism has not yet been fully clarified. Inordinate amount of catecholamines released into bloodstream after stress attack plays a crucial role in the pathogenesis of TTS. Symptoms of Takotsubo cardiomyopathy such as chest pain and dyspnea are similar to acute myocardial infarction due to it TTS requires careful diagnosis. The main tools for making diagnosis are echocardiography, coronary angiography, ECG, cardiac biomarkers and cardiac magnetic resonance. The syndrome is usually reversible, nevertheless number of patients may develop complications such as cardiogenic shock, arrhythmias, heart failure. Treatment is mostly supportive including Angiotensin-converting enzyme (ACEi) inhibitors and angiotensin receptor blockers (ARBs), which may reduce the likelihood of recurrent episodes. Generally patients with TSS have favourable prognosis, although some deaths are reported. This article is a review of current medical knowledge about Takotsubo syndrome based on available publications in Pubmed and Google Scholar databases.

Image Servo Tracking of a Flexible Manipulator Prototype with Connected Continuum Kinematic Modules

This paper presents the design and implementation of a flexible manipulator formed of connected continuum kinematic modules (CKMs) to ease the fabrication of a continuum robot with multiple degrees of freedom. The CKM consists of five sequentially arranged circular plates, four universal joints intermediately connecting five circular plates, three individual actuated tension cables, and compression springs surrounding the tension cables. The base and movable circular plates are used to connect the robot platform or the neighboring CKM. All tension cables are controlled via linear actuators at a distal site. To demonstrate the function and feasibility of the proposed CKM, the kinematics of the continuum manipulator were verified through a kinematic simulation at different end velocities. The correctness of the manipulator posture was confirmed through the kinematic simulation. Then, a continuum robot formed with three CKMs is fabricated to perform Jacobian-based image servo tracking tasks. For the eye-to-hand (ETH) experiment, a heart shape trajectory was tracked to verify the precision of the kinematics, which achieved an endpoint error of 4.03 in Root Mean Square Error (RMSE). For the eye-in-hand (EIH) plugging-in/unplugging experiment, the accuracy of the image servo tracking system was demonstrated in extensive tolerance conditions, with processing times as low as 58±2.12 s and 83±6.87 s at the 90% confidence level in unplugging and plugging-in tasks, respectively. Finally, quantitative tracking error analyses are provided to evaluate the overall performance.

RoboHeart: A Bi-Directional Zipping Actuator

Widespread adoption of soft robotic technologies is held back by the limitations of existing soft robotic actuators. One cause of the limited performance of soft actuators is their uni-polar stroke, which means only part of the work-cycle is powered. In this work, we introduce RoboHeart, a bi-directional compliant smart actuator. RoboHeart consists of two spring-steel strips covered with PVC insulation, pre-bent into a heart shape and is driven by dielectrophoretic zipping. Here, we perform isotonic and isometric characterisation of RoboHeart performance, demonstrating work output of 17 mJ (expansion) and 18 mJ (contraction) and power of 1.5 mW (expansion) and 2 mW (contraction). We then confirm the practical application of RoboHeart by demonstrating a 10-RoboHeart ring configuration capable of gripping a range of objects as they are lifted. We also demonstrate bidirectional control of actuation using three separate control channels. We believe that RoboHeart represents a step towards high-performance soft actuators and technologies.

Correlation between Cardiac Ultrasound Index and Cardiovascular Risk in Healthy Obese and Overweight Populations.

Objective To investigate the correlation of obesity and overweight with cardiac ultrasound parameters and future cardiovascular risk among healthy populations. Methods Basic clinical characteristics as well as cardiac ultrasound parameters were collected from healthy people. Firstly, all participants were divided into three groups: normal, overweight, and obese. Then the differences in cardiac ultrasound parameters between the three groups were calculated. Subsequently, those aged 35–60 years were screened to determine their cardiovascular risk according to the SCORE system. Finally, the correlation between cardiac ultrasound indices and cardiovascular risk was calculated. Results A total of 1328 healthy participants were included, of whom 504 were normal, 580 were overweight and 244 were obese. Obesity and overweight significantly increased the aorta, left atrium, right atrium, right ventricle, the end-diastolic diameter of the left ventricle, main pulmonary artery, right ventricular outflow tract, interventricular septum, left ventricular posterior wall, and triglycerides and decreased E/A values and high-density lipoprotein-cholesterol. Ejection fraction, fractional shortening, low-density lipoprotein-cholesterol, and total cholesterol did not change between the three groups. A total of 781 participants were screened for SCORE scores. Obesity and being overweight significantly increased the incidence of future cardiovascular events, and lower E/A values were also associated with cardiovascular risk. All cardiac parameters were strongly associated with cardiovascular risk. Conclusion Our research demonstrates that obesity and overweight can damage heart shape and function and raise the risk of future cardiovascular events in people that are healthy. Cardiovascular risk and cardiac structural and functional impairments are significantly positively correlated.

Synthesis and in vivo evaluation of new steviol derivatives that protect against cardiomyopathy by inhibiting ferroptosis

Cardiovascular diseases (CVDs) remain the leading cause of death globally. Inhibiting ferroptosis and thus preventing cardiac cell death is a promising and effective strategy for cardiomyopathy prevention and therapy. Steviol, an ent-kaurene diterpenoid, possesses broad-spectrum bioactivity. In the present study, with the aim to discover new agents for CVDs treatment, 30 derivatives of steviol, including 22 new ones, were synthesized, and evaluated their protective activity in vivo using the doxorubicin (DOX) induced zebrafish cardiomyopathy model. Our results firstly demonstrated that steviol has promising cardioprotective activity and further modification of steviol can greatly improve the activity. Among the new derivatives, 16d and 16e show the most potent activity. Both 16d (1 μM) and 16e (0.1 μM) effectively maintain the normal heart shape and prevent the cardiac dysfunction impaired by DOX in zebrafish. Their therapeutic efficacy is much superior to the parent natural product, steviol, and positive drug, levosimendan. Further study demonstrated that 16d and 16e inhibit DOX-induced ferroptosis and thus protect cardiomyopathy, by suppressing the glutathione depletion, iron accumulation, and lipid peroxidation, decreasing reactive oxygen species overaccumulation, and restoring the mitochondrial membrane potential. Consequently, due to their unique structure and significant cardioprotective activity with ferroptosis inhibition, new steviol derivatives 16d and 16e merit further research for the development of new cardioprotective drug candidates.

Protective effects of salvianolic acid A on clozapine-induced cardiotoxicity in zebrafish.

The clinical use of clozapine (CLZ), an atypical antipsychotic drug, was affected by side effects, such as cardiotoxicity. We selected normally developing zebrafish embryos to explore the antagonism of salvianolic acid A (SAA) against clozapine-induced cardiotoxicity. Embryos were treated with CLZ and SAA, and zebrafish phenotypes were observed at 24 h, 48 h, 72 h, and 96 h after treatment. The observed phenotypes included heart shape, heart rate, and venous sinus-arterial bulb (SV-BA) interval. Real-time quantitative PCR was used to detect changes in the expression of genes involved in heart inflammation, oxidative stress, and apoptosis. The results showed that SAA relieved pericardial edema, increased heart rate, and reduced the SV-BA interval. The PCR results also showed that when the zebrafish embryos were incubated with SAA and CLZ for 96 h, the expression of il-1b and nfkb2 were significantly downregulated, the expression of sod1 and cat were significantly upregulated, and the expressions of mcl1a and mcl1b were significantly downregulated. In summary, SAA can antagonize clozapine-induced cardiotoxicity.

A preliminary study on fetal cardiac morphology and systolic function of normal and anemic pregnant women by fetal heart quantification technology.

BackgroundMaternal anemia is a common nutritional problem during pregnancy. Fetal heart quantification (fetal HQ) technology is used to quantitatively evaluate the size, shape, and contractile function of the fetal heart, which can reflect the development of the fetus in the uterus.MethodsWe used fetal HQ technology to evaluate the basal-apical length (BAL), the transverse width (TW) and the area (A) of the four chamber view at end-diastole in 77 normal fetuses and 40 fetuses of women with anemia. We analyzed the changes of fetal heart size and measured the global sphericity index (GSI), the fraction area change (FAC), and the global longitudinal strain (GLS). The sphericity index (SI) and the fractional shortening (FS) of 24 segments were analyzed to identify any changes of fetal heart morphology and systolic function. The normal range of Z value was set at −2 to 2.ResultsFetal BAL, TW, A, and gestational age (GA) were positively linearly correlated, while GSI, GLS, and FAC had no significant correlation with GA. There was no significant difference in fetal BAL, TW, A, GLS, and FAC between the two groups (P>0.05). There was no significant difference in the FS of the 24 segments of the left and right ventricles between the two groups (P>0.05). There was no significant difference in the SI of the 1-24 segments of the right ventricle between the two groups (P>0.05). The difference in fetal GSI between the two groups was statistically significant (P<0.05). There was no significant difference in SI between the 1–22 segments of the left ventricle between the two groups (P>0.05), but there was a statistically significant difference between the 23–24 segments (P<0.05).ConclusionsThe fetal HQ analysis technology can quickly and simply quantitatively assess the size, shape, and contractility of the fetal heart. Anemia in pregnant women has no significant effect on fetal heart size and systolic function; it only affects the morphology of the heart, showing that the heart tends to be spherical as a whole and some segments of the apical segment of the left ventricle are abnormal.

Design and characterization of polarization reconfigurable heart shape monopole antenna for 2.4 GHz application

&lt;span&gt;This article represented a heart shape reconfigurable monopole antenna with polarization diversity. The proposed antenna is fed by a 50 Ω microstrip feed line that is printed on a flexible FR-4 (εr=4.4) substrate. The antenna comprises a ring-slot, a cross slot and four positive-intrinsic-negative (PIN) diodes that are soldered on ring slot. Four PIN diodes act as a switch and by controlling these PIN diodes effective current direction is changed hence four various states of polarization are achieved. Four states of polarization such as horizontal linear polarization (H-LP), vertical linear polarization (V-LP), right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) can be switched easily with the help of these PIN diodes and achieved an efficiency of more than 90%. Proposed antenna shows voltage standing wave ratio (VSWR)&amp;lt;2 at all working frequency and -10 dB reflection coefficients (RC) bandwidths (BW) (i.e., S11≤-10 dB) about 32.86% for linear polarization (LP) states while RHCP and LHCP states possess BW of about 31.61% and 31.67% respectively. It also shows axial ratio (AR) BW of 3.41% and 2.44% for RHCP and LHCP, respectively. Besides, the antenna has a well-suited omnidirectional pattern with a positive gain of all working frequency of interest where cross-polarization level is much lower than that of antenna gain.&lt;/span&gt;

Automatic 3D+t four-chamber CMR quantification of the UK biobank: integrating imaging and non-imaging data priors at scale.

Accurate 3D modelling of cardiac chambers is essential for clinical assessment of cardiac volume and function, including structural, and motion analysis. Furthermore, to study the correlation between cardiac morphology and other patient information within a large population, it is necessary to automatically generate cardiac mesh models of each subject within the population. In this study, we introduce MCSI-Net (Multi-Cue Shape Inference Network), where we embed a statistical shape model inside a convolutional neural network and leverage both phenotypic and demographic information from the cohort to infer subject-specific reconstructions of all four cardiac chambers in 3D. In this way, we leverage the ability of the network to learn the appearance of cardiac chambers in cine cardiac magnetic resonance (CMR) images, and generate plausible 3D cardiac shapes, by constraining the prediction using a shape prior, in the form of the statistical modes of shape variation learned a priori from a subset of the population. This, in turn, enables the network to generalise to samples across the entire population. To the best of our knowledge, this is the first work that uses such an approach for patient-specific cardiac shape generation. MCSI-Net is capable of producing accurate 3D shapes using just a fraction (about 23% to 46%) of the available image data, which is of significant importance to the community as it supports the acceleration of CMR scan acquisitions. Cardiac MR images from the UK Biobank were used to train and validate the proposed method. We also present the results from analysing 40,000 subjects of the UK Biobank at 50 time-frames, totalling two million image volumes. Our model can generate more globally consistent heart shape than that of manual annotations in the presence of inter-slice motion and shows strong agreement with the reference ranges for cardiac structure and function across cardiac ventricles and atria.

Cardiac Remodelling Following Cancer Therapy: A Review.

Cardiac remodelling is characterized by abnormal changes in the function and morphological properties such as diameter, mass, normal diameter of cavities, heart shape, fibrosis, thickening of vessels and heart layers, cardiomyopathy, infiltration of inflammatory cells, and some others. These damages are associated with damage to systolic and diastolic abnormalities, damage to ventricular function, and vascular remodelling, which may lead to heart failure and death. Exposure of the heart to radiation or anti-cancer drugs including chemotherapy drugs such as doxorubicin, receptor tyrosine kinase inhibitors (RTKIs) such as imatinib, and immune checkpoint inhibitors (ICIs) can induce several abnormal changes in the heart structure and function through the induction of inflammation and fibrosis, vascular remodelling, hypertrophy, and some others. This review aims to explain the basic mechanisms behind cardiac remodelling following cancer therapy by different anti-cancer modalities.

CFD-based approach to design the heart-shaped micromixer with obstacles

Abstract Microfluidic devices/systems, including Micro-Total-Analysis-System (µTAS), Point of Care Testing (POCT) and Lab-On-a-Chip (LOC) are used in many chemical and biological assays applications. Among the vital tasks that these microfluidic devices must achieve essentially include a high degree of mixing and accordingly, micromixers are being used for the same purpose. The design depends on the yield required in particular application. In the proposed study, the four kinds of heart-shaped micromixers with different obstacles have been studied through simulations. The influence of the shape and size of different obstacles viz., circular shape, diamond shape, teardrop shape, and heart shape obstacles on the performance characteristics has been studied. The performance characteristics namely, the mixing index and pressure drop have been used. In accordance with the study, a heart-shaped micromixer with heart shape obstacles (HSM-HSO) has come out to be the most efficient micromixer due to the significant chaotic convection effect. The heart-shaped micromixer with heart shape obstacles (HSM-HSO) of size 0.350 µm × 0.350 µm has shown better performance for a wider range of Reynolds number (Re), i.e., mixing index of Re &gt; 0.99, for Re of 0.1 and Re in the range of 15–45.

PKN2 deficiency leads both to prenatal 'congenital' cardiomyopathy and defective angiotensin II stress responses.

The protein kinase PKN2 is required for embryonic development and PKN2 knockout mice die as a result of failure in the expansion of mesoderm, cardiac development and neural tube closure. In the adult, cardiomyocyte PKN2 and PKN1 (in combination) are required for cardiac adaptation to pressure-overload. The specific role of PKN2 in contractile cardiomyocytes during development and its role in the adult heart remain to be fully established. We used mice with cardiomyocyte-directed knockout of PKN2 or global PKN2 haploinsufficiency to assess cardiac development and function using high resolution episcopic microscopy, MRI, micro-CT and echocardiography. Biochemical and histological changes were also assessed. Cardiomyocyte-directed PKN2 knockout embryos displayed striking abnormalities in the compact myocardium, with frequent myocardial clefts and diverticula, ventricular septal defects and abnormal heart shape. The sub-Mendelian homozygous knockout survivors developed cardiac failure. RNASeq data showed up-regulation of PKN2 in patients with dilated cardiomyopathy, suggesting an involvement in adult heart disease. Given the rarity of homozygous survivors with cardiomyocyte-specific deletion of PKN2, the requirement for PKN2 in adult mice was explored using the constitutive heterozygous PKN2 knockout. Cardiac hypertrophy resulting from hypertension induced by angiotensin II was reduced in these haploinsufficient PKN2 mice relative to wild-type littermates, with suppression of cardiomyocyte hypertrophy and cardiac fibrosis. It is concluded that cardiomyocyte PKN2 is essential for heart development and the formation of compact myocardium and is also required for cardiac hypertrophy in hypertension. Thus, PKN signalling may offer therapeutic options for managing congenital and adult heart diseases.

CT-Based Analysis of Left Ventricular Hemodynamics Using Statistical Shape Modeling and Computational Fluid Dynamics.

BackgroundCardiac computed tomography (CCT) based computational fluid dynamics (CFD) allows to assess intracardiac flow features, which are hypothesized as an early predictor for heart diseases and may support treatment decisions. However, the understanding of intracardiac flow is challenging due to high variability in heart shapes and contractility. Using statistical shape modeling (SSM) in combination with CFD facilitates an intracardiac flow analysis. The aim of this study is to prove the usability of a new approach to describe various cohorts.Materials and MethodsCCT data of 125 patients (mean age: 60.6 ± 10.0 years, 16.8% woman) were used to generate SSMs representing aneurysmatic and non-aneurysmatic left ventricles (LVs). Using SSMs, seven group-averaged LV shapes and contraction fields were generated: four representing patients with and without aneurysms and with mild or severe mitral regurgitation (MR), and three distinguishing aneurysmatic patients with true, intermediate aneurysms, and globally hypokinetic LVs. End-diastolic LV volumes of the groups varied between 258 and 347 ml, whereas ejection fractions varied between 21 and 26%. MR degrees varied from 1.0 to 2.5. Prescribed motion CFD was used to simulate intracardiac flow, which was analyzed regarding large-scale flow features, kinetic energy, washout, and pressure gradients.ResultsSSMs of aneurysmatic and non-aneurysmatic LVs were generated. Differences in shapes and contractility were found in the first three shape modes. Ninety percent of the cumulative shape variance is described with approximately 30 modes. A comparison of hemodynamics between all groups found shape-, contractility- and MR-dependent differences. Disturbed blood washout in the apex region was found in the aneurysmatic cases. With increasing MR, the diastolic jet becomes less coherent, whereas energy dissipation increases by decreasing kinetic energy. The poorest blood washout was found for the globally hypokinetic group, whereas the weakest blood washout in the apex region was found for the true aneurysm group.ConclusionThe proposed CCT-based analysis of hemodynamics combining CFD with SSM seems promising to facilitate the analysis of intracardiac flow, thus increasing the value of CCT for diagnostic and treatment decisions. With further enhancement of the computational approach, the methodology has the potential to be embedded in clinical routine workflows and support clinicians.

Triangular Srr Based Triple Band Amc Backed Antenna for High Gain Sub6ghz Application

This article describes a triple band monopole antenna. t has been assumed that the WiMAX band application is objective. In order to attain the required band, various iterations of the proposed antenna design are carried out. The proposed antenna in the shape of broken hearts operates in the frequency range of 3.2GHz to 4.1GHz. In the final iteration, the heart-shaped double slotted ring resonator (SRR) with two different radii is seen to improve the bandwidth (900MHz) and gain (3dB). In this design, additional parameters like VSWR (approximately 2 at the WiMAX band), impedance (real and imaginary), and efficiency (approximately 89%) have been observed. As a result, the proposed monopole antenna in the shape of a broken heart that operates in the WiMAX band exhibits high efficiency, reduced size, and moderate gain. which play a crucial role in the WIMAX application band.
