Different proficiency in minimally invasive surgery has great impact on efficacy of minimally invasive surgery. Therefore, great importance should be attached to the standardization of minimally invasive surgery. Accurate preoperative staging plays a prerequisite role which emphasizes multiple diagnostic strategies. Precise intraoperative procedure plays an essential role which should be performed according to the evidence-based expert consensus and guideline. Standardized postoperative management plays a crucial role which includes ex vivo lymph node dissection, registry of complication and follow-up and establishment of medical database...

Large-scale, cooperative rearrangements underlie the functions of RNA in RNA-protein machines and gene regulation. To understand how such rearrangements are orchestrated, we used high-throughput chemical footprinting to dissect a seemingly concerted rearrangement in P5abc RNA, a paradigm of RNA folding studies. With mutations that systematically disrupt or restore putative structural elements, we found that this transition reflects local folding of structural modules, with modest and incremental cooperativity that results in concerted behavior...

The aesthetic outcome of a well-planned and executed vascularized composite tissue face allotransplant is unquestionable; however, complete functional restoration is necessary. The authors studied the possibility of restoring tear duct function in face transplant recipients. They also examined the technical specifics and feasibility of incorporating a lacrimal drainage apparatus into facial allografting. The authors performed a standardized face vascularized composite allograft on 4 hemi-faces (2 fresh cadavers)...

Anatomy knowledge is not only essential for surgeons but also has importance for anyone who performs an invasive procedure on a patient, and provides examination and diagnosis of patients and sharing of these findings to the patient and other medical professionals. It is accepted that most surgical procedures could facilitate anatomic perception in surgical internships. There is an educational tendency to explore innovative instructional tools and methods that can help support current education styles. This study investigates the effect of a green laser pointer on students' perceptions and educational effectiveness when neck dissection is performed in the operating room...

RATIONALE: Castleman disease is a rare lymphoproliferative disorder which etiology is unknown. It is divided into 2 subtypes: the plasma cell variant and the hyaline vascular variant. The most common site is the hilum of the lungs and mediastinum. Castleman disease is often ignored by clinicians because of not frequently encountering in clinical and the lower uptake of F-FDG. Here, we report a case of hepatocellular carcinoma accompanied by Castleman disease in the hilum of the liver, which was misdiagnosed as the lymph node metastasis in F-FDG PET/CT imaging...

In this review article, I will outline my way of thinking about biologically active small molecules. The structure of liposidomycin B from Streptomyces species resulted in my initial sense that a structure tells its function. A biologically active small molecule may save directly or indirectly a number of people. Even if the molecule has not been used as a therapeutic agent, it can be used as a useful chemical probe for dissecting a living cell into different biochemical pieces. Such biologically active small molecules derived from microorganisms have been primarily found in cultivable microorganisms that make up only 1% of total microbes in nature...

Granular cell tumors (GCTs) usually develop in patients aged 30-50 years in the skin, tongue, and mammary gland, with 5-9% of GCTs occurring on the esophagus, ascending colon, and cecum. We report a case of gastric GCT in a 16-year-old male who presented with nausea and abdominal discomfort. Esophagogastroduodenoscopy (EGD) revealed an elastic hard and yellowish submucosal tumor of the gastric cardia anterior wall. GCT was suspected upon biopsy ; after total endoscopic submucosal dissection, histology of the resected tumor confirmed the diagnosis...

Introduction Laparoscopic cholecystectomy (LC) is the most commonly done, minimally invasive surgical procedure. Routinely used electrocautery produces more smoke, which masks the operating field, thereby prolongs the surgery and posing an increased risk of gallbladder (GB) perforation. The titanium clips used for clipping the cystic artery and cystic duct have a risk of slippage, which may lead to bleeding, and an increased risk for bile leakage. In addition, it may act as a nidus for stone formation. Advanced energy sources, such as the harmonic scalpel, though expensive, may provide the advantage of shorter operating time by reducing smoke, bloodless dissection in the GB bed, lower risk of bleeding from the cystic artery due to secure vessel sealing, and avoiding the use of a larger number of titanium clips...

Zebrafish could be an interesting translational model to understand and improve the post-infarction trial and possible regeneration in humans. The adult zebrafish is able to regenerate efficiently after resecting nearly 20% of the ventricular apex. This process requires the concert activation of the epicardium and endocardium, as well as trans-differentiation of pre-existing cardiomyocytes that together replace the lost tissue. The molecular mechanisms involved in this activation process are not completely clarified...

Pathogenic conditions involving degeneration of spinal motor neurons (MNs), such as amyotrophic lateral sclerosis, sarcopenia, and spinal cord injury, mostly occur in individuals whose spinal MNs are fully mature. There is currently no effective treatment to prevent death or promote axonal regeneration of the spinal MNs affected in these patients. To increase our understanding and find a cure for such conditions, easily controllable and monitorable cell culture models allow for a better dissection of certain molecular and cellular events that cannot be teased apart in whole organism models...

Iatrogenic acute dissection of the ascending aorta is a serious but rare complication of cardiac catheterization and percutaneous coronary intervention (PCI). Although treatment of ascending aortic dissection may require surgical repair, stenting at the origin of the dissection area may be sufficient in aortocoronary dissection (AD) following PCI. Described is the case of a 64-year-old female patient who was treated with PCI for a critical lesion of the right coronary artery (RCA). Immediate stenting at the source of the dissection was sufficient to repair the RCA lesions and successfully seal the site of retrograde propagation of the dissection...
