Cellular senescence is a mechanism that virtually irreversibly suppresses the proliferative capacity of cells in response to various stress signals. This includes the expression of activated oncogenes, which causes Oncogene-Induced Senescence (OIS). A body of evidence points to the involvement in OIS of chromatin reorganization, including the formation of senescence-associated heterochromatic foci (SAHF). The nuclear lamina (NL) is an important contributor to genome organization and has been implicated in cellular senescence and organismal aging...

BACKGROUND: Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging has enabled the accurate assessment of myocardial infarction (MI). However, LGE CMR has not been performed successfully in the fetus, where it could be useful for animal studies of interventions to promote cardiac regeneration. We believe that LGE imaging could allow us to document the presence, extent and effect of MI in utero and would thereby expand our capacity for conducting fetal sheep MI research...

This study tested the hypothesis that extracorporeal shock wave (ECSW) treatment can improve ischemia-induced left ventricular (LV) dysfunction in mini-pig with co-existing chronic kidney disease (CKD). LV ischemia in mini-pigs was induced by applying an ameroid constrictor over mid-left anterior descending artery (LAD), while model of CKD was established by right nephrectomy with partial ligation of left renal arterioles 2 weeks before LAD constriction. Thirty mini-pigs were randomly divided into group 1 (sham-control), group 2 (LV-ischemia), group 3 (LV-ischemia + CKD), Group 4 [LV-ischemia + ECSW (applied 1200 shots at 0...

OBJECTIVE: To investigate the effects of circulating microvesicles derived from myocardial ischemia (I-MVs) on apoptosis in myocardial ischemia/reperfusion (I/R) injury in rats. METHODS: I-MVs from rats undergoing myocardial left anterior descending (LAD) coronary artery ligation were isolated by ultracentrifugation from circulating blood and characterized by flow cytometry. I-MVs were administered intravenously (4.8 mg/kg) at 5 min before reperfusion procedure in I/R injury model which was induced by 30-min of ischemia and 120-min of reperfusion of LAD in rats...

BACKGROUND: The association of obesity with atrial fibrillation (AF) and with ventricular arrhythmias is well documented. OBJECTIVE: The aim of this study was to investigate whether weight reduction by a laparoscopic sleeve gastrectomy has any effect on P wave dispersion (PWD), a predictor of AF, and corrected QT interval dispersion (CQTD), a marker of ventricular arrhythmias, in obese individuals. METHODS: In a prospective study, a total of 114 patients (79 females, 35 males) who underwent laparoscopic sleeve gastrectomy were examined...

BACKGROUND: Common clinical tests often fail to identify posterior cruciate ligament (PCL) ruptures, leading to undetected tears and potential degenerative changes in the knee. The lateral-anterior drawer (LAD) test has been proposed but not yet evaluated regarding its effectiveness for diagnosing PCL-ruptures. HYPOTHESIS: The LAD will show greater tibial translation values in lateral-anterior direction in a PCL-Cut condition compared to a PCL-Intact condition, thus serving as a useful test for clinical diagnosis of PCL integrity...

We aimed to compare the differences of the effects on chronic myocardial ischemia (MI) of acupuncture at PC6 and ST36. The chronic MI model of minipigs was created by implanting an Ameroid constrictor on the left anterior descending coronary artery (LAD) and then two weeks' acupuncture was stimulated at PC6 or ST36, respectively. The results showed that both acupoints' stimulation decreased the serous cardiac troponin T (cTnT) and ischemia modified albumin (IMA) significantly and improved the ischemic ECG changes...

Kluyveromyces marxianus, as unconventional yeast, attracts more and more attention in the biofuel fermentation. Although this sort of yeasts can ferment pentose sugars, the fermentation capacity differs largely. Xylose and arabinose fermentation by three K. marxianus strains (K. m 9009, K. m 1911 and K. m 1727) were compared at different temperatures. The results showed that the fermentation performance of the three strains had significant difference under different fermentation temperatures. Especially, the sugar consumption rate and alcohol yield of K...

BACKGROUND: Experimental studies suggest that angiotensin II-receptor blockers can influence atrial remodeling and may prevent atrial fibrillation (AF). Therefore, we hypothesized that irbesartan may prevent the recurrence of AF following either catheter ablation or electrical cardioversion of AF. METHODS: Study on the Effect of Irbesartan on Atrial Fibrillation Recurrence in Kumamoto (SILK study) is a prospective, multicenter, randomized, and open-label comparative evaluation of the effects of irbesartan and amlodipine on AF recurrence in hypertensive patients with AF who are scheduled to undergo catheter ablation or electrical cardioversion of AF...

BACKGROUND: The traditional herbal compound Danggui Buxue decoction (DBD), has long been used for the prevention and treatment of cardiovascular diseases, however, the underlying molecular mechanism for its effect remains still unknown. So this study would to investigate the effect of DBD on cardiac damage induced by myocardial infarction (MI) challenge. METHODS: SD Rats with ligation of left anterior descending (LAD) coronary artery were randomly divided into MI, MI plus Betaloc Zok, MI plus DBD high dose, and MI plus DBD low dose group, together with sham-operated group...

Patients with de Winter syndrome, also termed anterior ST-segment elevation myocardial infarction (STEMI)-equivalent, represent 2% of all patients with acute anterior myocardial infarctions admitted to emergency departments (EDs). STEMI-equivalents do not present with classical electrocardiogram (ECG) changes but exhibit a critical stenosis of the left anterior descending (LAD) coronary artery. This is under-recognized by clinicians and is therefore associated with high morbidity and mortality. Here, we report a rare case of a novel, typical, STEMI-equivalent ECG pattern without obvious ST-segment elevation in a 34-year-old female who presented to our ED with substantial chest pain and a large, acute, transmural anterior myocardial infarction caused by acute occlusion of the LAD coronary artery...

Ions of high energy and high charge are accelerated from compact intense laser produced plasmas and are routinely analysed either by time of flight or Thomson parabola spectrometry. At the highest intensities where ion energies can be substantially large, both these techniques have limitations. Strong electromagnetic pulse noise jeopardises the arrival time measurement, and a bright central spot in the Thomson parabola spectrometer affects the signal to noise ratio of ion traces that approach close to the central spot...

Obstruction of left anterior descending artery (LAD) due to the thrombosis or atherosclerotic plaques is the leading cause of death worldwide. Targeted delivery of drugs through micro- and nanoparticles is a very promising approach for developing new strategies in clot-busting or treating restenosis. In this work, we modelled the blood flow characteristics in a patient-specific reconstructed LAD artery by the fluid-solid interaction method and based on physiological boundary conditions. Next, we provided a Lagrangian description of micro- and nanoparticles dynamics in the blood flow considering their Brownian motion and the particle-particle interactions...

To date, ocular antibody therapies for the treatment of retinal diseases rely on injection of the drug into the vitreous chamber of the eye. Given the burden for patients undergoing this procedure, less frequent dosing through the use of long-acting delivery (LAD) technologies is highly desirable. These technologies usually require a highly concentrated formulation and the antibody must be stable against extended exposure to physiological conditions. Here we have increased the potential of a therapeutic antibody antigen-binding fragment (Fab) for LAD by using protein engineering to enhance the chemical and physical stability of the molecule...

There is a considerable amount of data that using more than one arterial graft provides a survival advantage for patients undergoing coronary bypass operations. The Society of Thoracic Surgeons has a set of official guidelines for the use of arterial grafts which include the following recommendations:Internal mammary arteries (IMA's) should be used to bypass the left anterior descending (LAD) artery when bypass of the LAD is indicated.As an adjunct to left internal mammary artery (LIMA), a second arterial graft (right IMA or radial artery [RA]) should be considered in appropriate patients...

BACKGROUND: Mast cells are important modulators of the human immune system via their release of several inflammatory mediators and proteases. The release can be activated by different pathways: the classical immunoglobulin E-dependent pathway and by the non-immunological immunoglobulin E-independent pathway. MAS-related G protein-coupled receptor X2 (MRGPRX2) is expressed in mast cells and it is one of the endogenous receptor responsible for the IgE-independent activation of human mast cell...

A 45-year-old female was admitted for a transient anterior ST-segment elevation myocardial infarction (STEMI). Coronary angiogram showed a diffuse severe stenosis of the distal left anterior descending (LAD) coronary artery, which was managed medically. Three years later, a recurrent transient anterior STEMI led to a second coronary angiography showing a tubular stenosis of the mid-LAD with normal distal coronary bed. An optical coherence tomography (OCT) revealed a spontaneous coronary artery dissection (SCAD) with an extensive compressive mural hematoma without any intimal tear...

Transmembrane collagen XVII (COL17) is a hemidesmosomal component of basal keratinocytes that can be targeted by autoantibodies in autoimmune blistering disorders, including linear IgA dermatosis (LAD). The COL17 can be physiologically cleaved within the juxtamembranous extracellular NC16A domain, and LAD autoantibodies preferentially react with the processed ectodomains, indicating that the processing induces neoepitopes. However, the details of how neoepitopes develop have not been elucidated. In this study, we show that C-terminal processing of COL17 also plays a role in inducing neoepitopes for LAD autoantibodies...

PURPOSE: Fluid-attenuated inversion recovery vascular hyperintensity (FVH) is often observed in conjunction with acute ischemic stroke (AIS) of the carotid system. Despite its bearing on patient care outcomes, factors influencing FVH and its clinical significance in patients with transient ischemic attacks (TIAs) of the carotid arterial system have yet to be evaluated. METHODS: Consecutive inpatients (N = 154) diagnosed with TIAs of the carotid system in a 2-year period (2012-2014) were enrolled in our study...
