BACKGROUND: This study evaluated the efficacy of a teaching method using simulated B-lines of hand ultrasound with a wet foam dressing material. METHODS: This prospective, randomized, noninferiority study was conducted on emergency medical technician students without any relevant training in ultrasound. Following a lecture including simulated (SG) or real video clips (RG) of B-lines, a posttest was conducted and a retention test was performed after 2 months. The test consisted of questions about B-lines in 40 randomly mixed video clips (20 simulated and 20 real videos) with 4 answer scores (R-1 [the correct answer score for the real video clips] vs S-1 [the correct answer score for the simulated video clips] in the posttest, R-2 [the correct answer score for the real video clips] vs S-2 [the correct answer score for the simulated video clips] in the retention test)...

Long-term submandibular duct obstruction is thought to cause irreversible atrophy and dysfunction of the submandibular gland. As an atrophic gland may be induced clinically by chronic or recurrent infection, it is generally removed surgically. However, the regenerative capacity of atrophic submandibular glands after long-term obstruction is not completely understood. We studied the regenerative capacity of the mouse submandibular duct using an aneurysm clip ligation model. We documented changes in the size, histologic structure and gene expression of the submandibular gland after 2 months of ligation, and 1 week, 1 month and 2 months after clip removal...

The over-the-scope-clip (OTSC) (Ovesco Endoscopy, Tübingen, Germany) is a revolutionary endoscopic tool for management of fistulas, perforations, and leaks [1]. Removal of an OTSC is rare and oftentimes challenging. We describe a simple and reproducible technique utilizing argon plasma coagulation (APC) to fracture the OTSC hinge to facilitate extraction.

Although the deleterious effects of sleep deprivation on memory consolidation are well documented, it is still unclear how the facilitating effect of emotions on memory consolidation processes could be modulated by the lack of sleep. In this study, we investigated the effects of sleep deprivation on episodic memory using emotional and non-emotional film stimuli. Forty-eight healthy subjects, divided into a sleep group (SG) and a sleep-deprived (SD) group, completed an Encoding and a Recall phase. Participants in the SD group were sleep deprived the night immediately following the Encoding phase, whereas the control group slept at home...

BACKGROUND: Omitting the placement of clips inside tumour bed during breast cancer surgery poses a challenge for delineation of lumpectomy cavity clinical target volume (CTVLC). We aimed to quantify inter-observer variation and accuracy for CT- and MRI-based segmentation of CTVLC in patients without clips. PATIENTS AND METHODS: CT- and MRI-simulator images of 12 breast cancer patients, treated by breast conserving surgery and radiotherapy, were included in this study...

Few studies have investigated the neural systems involved in decreasing behavioral reactivity to emotional stimuli as children age. It has been suggested that this process may interact with temperament-linked variations in neurodevelopment to better explain individual differences in the maturation of emotion regulation. In this investigation, children ages 4 to 12 (n = 30, mean age = 7.62 years, SD = 1.71 years) and adults (n = 21, mean age = 26.67 years) watched clips from popular children's films containing positive, negative, or neutral emotional content during functional magnetic resonance imaging...

The cross-linking of the IgA Fc receptor (FcαRI) by IgA induces release of the chemoattractant LTB4, thereby recruiting neutrophils in a positive feedback loop. IgA autoantibodies of patients with autoimmune blistering skin diseases therefore induce massive recruitment of neutrophils, resulting in severe tissue damage. To interfere with neutrophil mobilization and reduce disease morbidity, we developed a panel of specific peptides mimicking either IgA or FcαRI sequences. CLIPS technology was used to stabilize three-dimensional structures and to increase peptides' half-life...

Purpose: The filum terminale (FT) is a fibrous band that connects the conus medullaris to the posterior body of the coccyx. Considering the advances of ultrasonography (US) technology and improvements in the resolution of US images, we aimed to re-establish the US features of the normal FT in infants younger than 6 months of age. Methods: We retrospectively reviewed 30 spinal US scans, stored as video clips. The internal structure of the FT and the marginal echogenicity of the FT were assessed, and transverse and longitudinal US were compared...

Clip domain serine proteinases (ClipSPs) play an important role in the prophenoloxidase-activating (proPO) system. In the shrimp Penaeus monodon, the ClipSP PmClipSP2 has been previously shown to bind to microbial polysaccharides (LPS and β-1,3-glucan) and likely activates the proPO system. To reveal the binding site of the PmClipSP2 protein, the N-terminal clip domain (Clip-PmClipSP) and C-terminal SP domain (SP-PmClipSP2) were separately cloned. The recombinant proteins were then assayed for their binding properties and involvement in proPO activation...

MicroRNA-122, an abundant and conserved liver-specific miRNA, regulates hepatic metabolism and functions as a tumor suppressor, yet systematic and direct biochemical elucidation of the miR-122 target network remains incomplete. To this end, we performed Argonaute crosslinking immunoprecipitation (Argonaute [Ago]-CLIP) sequencing in miR-122 knockout and control mouse livers, as well as in matched human hepatocellular carcinoma (HCC) and benign liver tissue to identify miRNA target sites transcriptome-wide in two species...

Cerebral aneurysms in complex anatomical locations and intraoperative rupture of aneurysms are challenging for neurosurgeons and anaesthetists alike. Mechanical and non-mechanical methods to reduce blood flow into aneurysms are well-recognised techniques to facilitate aneurysm exclusion from the circulation. Mechanical methods like temporary clipping of parent arteries, carotid artery ligation and endovascular balloon occlusion are commonly used in clinical practice. However, non-mechanical techniques such as rapid ventricular pacing and adenosine-induced cardiac standstill with hypotension are still emerging strategies...

Existing literature suggests that use of telemedicine during postoperative appointments can increase access to care and is valued by patients and providers alike. While research examining the clinical equivalency of telemedicine visits for postoperative care has been growing, few studies have reported on telemedicine follow-up after neurosurgery. This study examined if a videoconferencing visit could substitute for an in-person clinic visit for elective neurosurgical cases in the USA. This was a single-center prospective study of patients who underwent elective neurosurgical procedures (aneurysm clipping, resection of cavernous angiomas, resection of arterial venous malformation, microvascular decompression for trigeminal neuralgia and hemifacial spasm, and certain benign brain tumors) and were offered telemedicine follow-up care by an allied health professional during the first 90 days after neurosurgery...

BACKGROUND AND AIMS: Small bowel and colorectal muscle biopsies require a surgical approach. Advancing our understanding of the pathophysiology of motility disorders, such as functional bowel disorders, intestinal pseudo-obstruction and slow transit constipation, is hindered by our inability to non-invasively obtain muscularis propria (MP) for evaluation of multiple cell types, including myenteric neurons. The aims of this study were to determine (1) technical feasibility, reproducibility and safety of performing duodenal endoscopic muscle biopsy (dEMB) and rectal endoscopic muscle biopsy (rEMB) using a clip-assist technique; and (2) presence of myenteric neurons in tissue samples...

The present study is an attempt to investigate the effects of long-term (75days) exposure to environmental estrogens (EE) on the swimming behaviour of zebrafish (Danio rerio). Adult zebrafish were exposed semi-statically to media containing commonly detected estrogenic water contaminants (EE2, DES and BPA) at a concentration (5ng/L) much lower than environmentally recorded levels. Time spent in swimming, surface preference, patterns and path of swimming were recorded (6mins) for each fish using two video cameras on day 15, 30 60 and 75...

BACKGROUND: Endoscopic submucosal dissection (ESD) is technically one of the most complicated endoscopic procedures. Traction methods have been reported to be effective for ESD. A recent study revealed that the S-O clip allowed faster and safer colonic ESD. We assessed the efficacy and safety of gastric ESD with the S-O clip for gastric epithelial neoplasm. METHODS: We performed a retrospective cohort study of patients treated for gastric ESD using the S-O clip between September and November 2016 (SO group, n = 48)...

BACKGROUND: Endovascular coil embolization and craniotomy with clip ligation are the two most commonly used treatments for ruptured cerebral aneurysm. While coiling maintains the advantages of brevity and complete avoidance of brain retraction and manipulation, clipping offers the benefits of decompression of the injured brain and lower aneurysm recurrence rates. A combined, immediately sequential treatment strategy for acutely ruptured cerebral aneurysm that simultaneously maximizes the advantages of both techniques, while minimizing their respective disadvantages, may be a useful paradigm...

Plants employ highly variable chemical defenses against a broad community of herbivores, which vary in their susceptibilities to specific compounds. Variation in chemical defenses within the plant has been found in many species; the ecological and evolutionary influences on this variation, however, are less well-understood. One central theory describing the allocation of defenses in the plant is the Optimal Defense Hypothesis (ODH), which predicts that defenses will be concentrated in tissues that are of high fitness value to the plant...
