The leaf area density (LAD) within a tree canopy is very important for the understanding and modeling of photosynthetic studies of the tree. Terrestrial light detection and ranging (LiDAR) has been applied to obtain the three-dimensional structural properties of vegetation and estimate the LAD. However, there is concern about the efficiency of available approaches. Thus, the objective of this s...

This study shows that L1-like adhesion (LAD-1), the sole Caenorhabditis elegans homologue of the L1 family of neuronal adhesion molecules, is required for proper development of the germline and the early embryo and embryonic and gonadal morphogenesis. In addition, the ubiquitously expressed LAD-1, which binds to ankyrin-G, colocalizes with the C. elegans ankyrin, UNC-44, in multiple tissues at ...

Advanced glycation end products (AGEs), known promoters of diabetic complications, form abundantly in heated foods and are ingested in bioreactive forms. To test whether dietary AGEs play a role in the progression of insulin resistance, C57/BL/KsJ db/db mice were randomly placed for 20 weeks on a diet with either a low AGE content (LAD) or a 3.4-fold higher content of AGE (high AGE diet [HAD]),...

Chemoresistance is one of the most significant obstacles in lung adenocarcinoma (LAD) treatment, and this process involves genetic and epigenetic dysregulation of chemoresistance-related genes. Previously, we have shown that restoration of microRNA (miR)-200b significantly reverses chemoresistance of human LAD cells by targeting E2F3. However, the molecular mechanisms involved in the silencing ...

OBJECTIVES In-stent restenosis (ISR) remains a major complication of percutaneous coronary intervention, even in the current era of drug-eluting stents (DESs). We reviewed the clinical and angiographic outcomes of coronary endarterectomy with stent removal using an off-pump technique in patients with ISR in the left anterior descending artery (LAD). METHODS Twelve patients with long-segment I...

We describe, in a 61 year old man, with coexistent aortic stenosis, the anomalous origin of posterior descending artery (PDA) from a stenotic left anterior descending (LAD) artery, as its continuation across the left ventricular apex, in the presence of a normally arising and atretic proximal right coronary artery. The patient underwent mechanical aortic valve replacement and triple coronary ar...

this study was conducted to determine whether precordial st segment depression in admission electrocardiogram (ecg) in patients with acute phase inferior myocardial infarction (mi) eligible for thrombolytic therapy and subsequent angiographic evaluation, influences the incidence of left anterior descending artery (lad) disease. 31 consecutively admitted patients were entered in our study. 20 pa...

background anomalous left coronary artery from the pulmonary artery (alcapa) is a rare congenital cardiovascular defect that occurs in approximately 1/300 000 live births or 0.5% of children with congenital heart disease. there are two types of alcapa syndrome: the infant type and the adult type. the most infants experience myocardial infarction and congestive heart failure, and approximately 9...
