BACKGROUND: For patients unable to receive heparin anticoagulation during haemodialysis, saline flushes to reduce circuit clotting are often the norm. Regional citrate anticoagulation (RCA) although effective is not used by many centres including in Singapore. We wanted to demonstrate the superiority and safety of a simple regional citrate anticoagulation regime, compared to saline flushes, for heparin-free low flux haemodialysis. METHODS: This is a prospective, open label, cross over study on 25 sequential haemodialysis sessions for inpatients receiving heparin-free haemodialysis...

BACKGROUND Coronary artery calcifications (CACs) are associated with coronary atherosclerosis and cardiovascular (CV) events. In "non-cardiovascular" settings, CACs can be easily detected on chest multi-detector computed tomography (MDCT). Their evaluation may help to better stratify CV risk in the general population, especially for primary prevention. AIMS We retrospectively evaluated the relationship between CAC distribution and CV risk, determined by Framingham Risk Score (FRS), in a cohort of patients who underwent chest MDCT performed for several clinical indications...

Background: The ascomycete fungus Trichoderma reesei is the predominant source of enzymes for industrial conversion of lignocellulose. Its glycoside hydrolase family 7 cellobiohydrolase (GH7 CBH) TreCel7A constitutes nearly half of the enzyme cocktail by weight and is the major workhorse in the cellulose hydrolysis process. The orthologs from Trichoderma atroviride (TatCel7A) and Trichoderma harzianum (ThaCel7A) show high sequence identity with TreCel7A, ~ 80%, and represent naturally evolved combinations of cellulose-binding tunnel-enclosing loop motifs, which have been suggested to influence intrinsic cellobiohydrolase properties, such as endo-initiation, processivity, and off-rate...

BACKGROUND: Electrical phenomenon and remote myocardial ischemia are the main factors of ST segment depression in inferior leads in acute anterior myocardial infarction (AAMI). We investigated the prognostic value of the sum of ST segment depression amplitudes in inferior leads in patients with first AAMI treated with primary percutaneous coronary intervention. (PPCI). METHODS: In this prospective analysis, we evaluated the in-hospital prognostic impact of the sum of ST segment depression in inferior leads on 206 patients with first AAMI...

Background: Root cause analyses (RCA) are often completed in health care settings to determine causes of adverse events (AEs). RCAs result in action plans designed to mitigate future patient harm. National reviews of RCA reports have assessed the safety of numerous health care settings and suggested opportunities for improvement. However, few studies have assessed the safety of receiving care from physical therapists, occupational therapists, or speech and language pathology pathologists...

Performing intervention of a single coronary artery (SCA) is challenging and technically difficult since a severe complication may be catastrophic if occurred. It requires a proper selection of instruments and well experienced operator to perform the intervention. However, a definitive standardization treatment for those patients is difficult; each case should be treated individually, according to the anatomical variations. We present three rare cases of SCA in setting of acute coronary syndrome (ACS) and culprit lesion in right coronary artery (RCA), treated successfully with percutaneous coronary intervention...

Coronary artery ectasia (CAE) is an uncommon anomaly, usually found in 1.2-2% of patients undergoing coronary angiography, defined as a segment of the coronary artery that has a diameter of more than 1.5 times the normal adjacent segments. Atherosclerosis is considered as the cause of half of the CAE cases. We herein present a 65-year-old Asian male with past medical history of Kawasaki disease (KD) who developed recurrent episodes of inferior wall ST-elevation myocardial infarction (STEMI) despite treatment with dual antiplatelet therapy (DAPT)...

A 61-year-old man with a history of percutaneous coronary intervention (PCI) of the mid right coronary artery (RCA) with a drug eluting stent (DES), presented with non-ST segment elevation myocardial infarction. Coronary angiography demonstrated complex disease of the distal RCA as well as in-stent stenosis of the previously placed mid RCA stent. The patient underwent bifurcation PCI of the distal RCA followed by attempted intervention with a DES on the mid RCA lesion. The stent could not cross the lesion and eventually became dissociated from its delivery system...

Pulse wave transit time (PWTT) has been widely used as an index in assessing arterial stiffness. Percutaneous coronary intervention (PCI) is usually applied to the treatment of coronary artery disease (CAD). Research on the changes in PWTT caused by PCI is helpful for understanding the impact of the PCI procedure. In addition, effects of stent sites and access sites on the changes in PWTT have not been explored. Consequently, this study aimed to provide this information. The results showed that PWTT significantly increased after PCI (p < 0...

Transcription factors (TFs) play central roles in the regulation of gene expression by binding with specific DNA sequences. As a potential diagnostic marker, sensitive detection of TFs is essential for pharmacological research development and clinical disease diagnosis. Here, a new fluorescent method based on target binding protection mediated rolling circle amplification (RCA) was developed for TFs detection. A hairpin probe with recognition site for target binding, cleavage site for Nt.BbvCI digestion and two hanging DNA strands with part of G-quadruplex complementary sequences for signal output was designed...

An ST segment elevation myocardial infarction (STEMI) that produces anterior ST segment elevation (STE) is typically caused by acute occlusion of the left anterior descending (LAD) artery. Anterior STE, however, may also be caused by acute occlusion of either the proximal right coronary artery (RCA) or the right ventricular marginal branch (RVB). It has been thought that, in contrast to occlusions of the LAD, proximal RCA/RVB occlusion rarely causes Q waves in the right precordial leads. We present a case where a proximal RCA occlusion produced not only anterior STE, but also anterior T wave inversions and anterior Q waves...

We proposed a terminal deoxynucleotidyl transferase (TdT)-assisted rolling circle amplification (RCA) strategy for the amplified detection of genome-containing biological targets. The synergetic signal amplification of DNase I-mediated genomic DNA fragmentation and subsequent RCA allow the sensing platform to have extraordinarily high sensitivity.

Intramural hematoma (IMH) of ascending aorta is a rare but potentially lethal form of acute aortic syndrome (AAS). It is characterized by a hematoma within the media layer of the aorta secondary to rupture of the vasa vasorum in the absence of an intimal tear. However, the theory of "micro-tear" which cannot be easily detected has been raised. It may stabilize, regress, or progress to rupture or dissection. Similar to Type A aortic dissection (AD), patients with IMH of ascending aorta, as well as patients with persistent pain, are treated urgent surgery...

BACKGROUND: Coronary artery anomalies (CAAs) are congenital variations of one or more of the coronary arteries and they are an uncommon but important cause of chest pain and, in some cases, sudden cardiac death. Anomalies of coronary arteries may be found incidentally in 0.3-1% of healthy individuals. The three types of coronary artery anomalies are anomalies of origin, anomalies of course and anomalies of termination. The purpose of our study was to estimate the frequency of CAAs in Canton Sarajevo, B&H, and to deteremine the prevalence of origin, course and termination anomalies of coronary arteries...

A comprehensive study on characterization and genetic diversity analysis was carried out in 16 'Ogura'-based 'CMS' lines of cabbage using 14 agro-morphological traits and 29 SSR markers. Agro-morphological characterization depicted considerable variations for different horticultural traits studied. The genotype, ZHA-2, performed better for most of the economically important quantitative traits. Further, gross head weight (0.76), head length (0.60) and head width (0.83) revealed significant positive correlation with net head weight...

The prevalence of the left circumflex coronary artery (LCx) as the culprit vessel in ST-segment-elevation myocardial infarction (STEMI) is reportedly lowest among that of the 3 main epicardial arteries, and has not been described for non-STEMI (NSTEMI) and stable angina pectoris. We sought to define the distribution of culprit arteries in these clinical presentations and suggest mechanisms for the differences. We reviewed 189 coronary angiograms of patients with STEMI, 203 with NSTEMI, and 548 with stable angina (n=940), and compared distributions of stenotic and culprit coronary arteries (lesions prompting intervention)...
