BACKGROUND Small-bowel obstruction (SBO) is a common dilemma faced by general surgeons. A timely and accurate diagnosis is crucial, based on history, physical examination, and radiographic studies. A computed tomography (CT) scan has become an increasingly common diagnostic modality. The aim of this study was to define a set of CT criteria that may help(More)
Small RNA research is a rapidly growing field. Apart from microRNAs, which are important regulators of gene expression, other types of functional small RNA molecules have been reported in animals and plants. MicroRNAs are important in host-microbe interactions and parasite microRNAs might modulate the innate immunity of the host. Furthermore, small RNAs can(More)
BACKGROUND Obtaining informed consent before performing invasive procedures and operations has become a standard practice at all medical institutions in the United States. All agree that patients should be both conscious of and in agreement with their medical care. Though patients routinely sign consent forms with numerous risks and complications detailed,(More)
INTRODUCTION A wandering spleen occurs when there is a laxity of the ligaments that fix the spleen in its normal anatomical position. CASE REPORT We present the case of a wandering spleen in a 20-year-old female who presented with recurrent pancreatitis and underwent a laparoscopic splenectomy. DISCUSSION The presentation of a wandering spleen varies(More)
BACKGROUND Surgical education has undergone radical changes in the past decade. The introductions of laparoscopic surgery and endovascular techniques have required program directors to alter surgical training. The 6 competencies are now in place. One issue that still needs to be addressed is the business aspect of surgical practice. Often residents complete(More)
Early global measures of genome complexity (power spectra, the analysis of fluctuations in DNA walks or compositional segmentation) uncovered a high degree of complexity in eukaryotic genome sequences. The main evolutionary mechanisms leading to increases in genome complexity (i.e. gene duplication and transposon proliferation) can all potentially produce(More)
High-throughput sequencing (HTS) data for small RNAs (noncoding RNA molecules that are 20-250 nucleotides in length) can now be routinely generated by minimally equipped wet laboratories; however, the bottleneck in HTS-based research has shifted now to the analysis of such huge amount of data. One of the reasons is that many analysis types require a Linux(More)
The 2017 update of NGSmethDB stores whole genome methylomes generated from short-read data sets obtained by bisulfite sequencing (WGBS) technology. To generate high-quality methylomes, stringent quality controls were integrated with third-part software, adding also a two-step mapping process to exploit the advantages of the new genome assembly models. The(More)
The analysis of whole genome DNA methylation patterns is an important first step towards the understanding on how DNA methylation is involved in the regulation of gene expression and genome stability. Previously, we published MethylExtract, a program for DNA methylation profiling and genotyping from the same sample. Over the last years we developed it(More)
