#1
Jaihwan Kim
Endoscopic retrograde cholangiopancreatography (ERCP) is a key endoscopy skill used to diagnose and treat pancreatobiliary diseases. However, its diagnostic use is decreasing in favor of other less invasive methods such as magnetic resonance cholangiopancreatography and endoscopic ultrasound. Alternatively, its use has become more important in the therapeutic area. ERCP trainees must know the anatomy and physiology of the pancreatobiliary system, several key basic skills, and complications of a successful procedure...

The metacercariae of Artyfechinostomum malayanum (Leiper, 1911) Mendheim, 1943 were discovered in Pila sp. snails purchased from a market in Phnom Penh, Cambodia. They were isolated from the snails using the artificial digestion technique and were orally fed to 2 hamsters, 1 rat, and 2 mice to obtain the adult flukes. The metacercariae were round, 145-165 μm in diameter, having a cyst wall of 6-10 μm in thickness, a head collar and collar spines, and characteristic features of excretory granules. Adult flukes were recovered in the small intestines of the animals at days 14 and 32 post infection and were morphologically observed using a light microscope and a scanning electron microscope...

Angiostrongylus cantonensis invades the central nervous system (CNS) of humans to induce eosinophilic meningitis and meningoencephalitis and leads to persistent headache, cognitive dysfunction, and ataxic gait. Infected mice (nonpermissive host), admittedly, suffer more serious pathological injuries than rats (permissive host). However, the pathological basis of these manifestations is incompletely elucidated. In this study, the behavioral test, histological and immunohistochemical techniques, and analysis of apoptotic gene expression, especially caspase-3, were conducted...

BACKGROUND: Autologous fat grafting is a common procedure for soft-tissue reconstruction but is associated with a graft resorption rate ranging from 20% to 80%. To improve the fat graft survival rate, a new technique, called cell-assisted lipotransfer (CAL), was developed. With CAL, fat is injected along with adipose-derived stromal cells (ASCs) that are assumed to improve fat survival rate. We conducted an evidence-based meta-analysis to evaluate the efficacy and safety of CAL as compared with conventional autologous fat grafting (non-CAL)...

AIM: To compare intra-amniotic versus fetal subcutaneous injections for selective fetal labeling in multifetal rat pregnancies. METHODS: A total of 14 pregnant rats were randomized to receive intra-amniotic injections of dyes (including Fluorescein, Indigo Carmine, or Evans Blue) or fetal subcutaneous injections (of commercial tattoo ink) both guided by ultrasound at 15-17 days of gestation. Survival, injection, and labeling success rates of both techniques were compared...

To cut the high mortality rate of malignant disease such as pancreatic cancer, development of newly diagnostic probes for early stage detection of tumor lesions is required. Multimodal imaging nanoprobes allowing targeted and real time functional/anatomical imaging of tumors meet the demands. For this purpose, a MRI/optical dual-modality probe based on biodegradable magnetic iron oxide nanoworms has been developed. The cross-linked surface of nanoworms were anchored to fluorescent dyes and to FITC.PTR86; a novel synthetic peptide with high affinity towards somatostatin receptors...

A method for fast determination of the activity in soil samples by measuring a fresh soil core sample from both ends with an HPGe-detector is proposed. The method was tested by simulations, as well as by measurements on spiked soil samples. Both simulations and measurements showed that the geometrical mean of the count rates when the sample is measured twice, with the bottom and the top end, respectively, facing the detector closely resembles the count rate from a measurement on a homogenized sample. Therefore, an efficiency calibration for homogenized samples could be used even if the activity is highly inhomogeneous in the soil core, as is the case with fresh fallout...

Ongoing research activities are targeted to explore high photocatalytic activity of TiO2-based photocatalysts for the degradation of environmental contaminants under UV and visible light irradiation. In this work, we devise a facile, cost-effective technique to in situ synthesize hierarchical SiO2@C-doped TiO2 (SCT) hollow spheres for the first time. This strategy mainly contains the preparation of monodisperse cationic polystyrene spheres (CPS), sequential deposition of inner SiO2, the preparation of the sandwich-like CPS@SiO2@CPS particles, and formation of outer TiO2...

Impaired arm swing is a common motor symptom of Parkinson's disease (PD), and correlates with other gait impairments and increased risk of falls. Studies suggest that arm swing is not merely a passive consequence of trunk rotation during walking, but an active component of gait. Thus, techniques to enhance arm swing may improve gait characteristics. There is currently no portable device to measure arm swing and deliver immediate cues for larger movement. Here we test report pilot testing of such a device, ArmSense (patented), using a crossover repeated-measures design...

BACKGROUND: There are various techniques and approaches for lumbar interbody fusion differing in access, cage type and type of supplemental posterior instrumentation. While a transforaminal access usually includes a hemifacetectomy, the facet joint can be preserved with a more lateral extraforaminal access. The supplemental posterior instrumentation required for both fusion techniques is still debated. The purpose of the present study was to compare primary stability of the two accesses for two different cage types with none, unilateral and bilateral supplemental posterior instrumentation...

Few surgical techniques have been described for reconstruction in massive osteochondral lesions of the talus, and there is limited evidence of techniques for accurately reproducing native talar anatomy with bone auto/allograft techniques. In this article, we present a novel technique, which is highly reproducible, using bone cement to restore the congruence and anatomy of the ankle joint. LEVELS OF EVIDENCE: Level V: Technical tip.

Eupatilin (5,7-dihydroxy-3,4,6-trimethoxyflavone) is one of the main compounds present in Artemisia species. Eupatilin has both antioxidative and anti-inflammatory properties and a relaxation effect on vascular contraction regardless of endothelial function. We evaluated the relaxant effects of eupatilin on the corpus cavernosum (CC) of rabbits and the underlying mechanisms of its activity in human corpus cavernosum smooth muscle (CCSM) cells. Isolated rabbit CC strips were mounted in an organ bath system. A conventional whole-cell patch clamp technique was used to measure activation of calcium-sensitive K(+) -channel currents in human CCSM cells...

Despite the sheer number of pediatric tonsillectomies performed in the United States annually, there is no clear consensus as to which surgical technique is superior. One way to compare surgical techniques is to study the morbidity associated with each. We report postoperative hemorrhage rates, one of the frequently encountered major adverse events, as part of a retrospective chart review across four different surgical techniques. These surgeries involved either (1) Coblation, (2) Co-blation with partial suture closure of the tonsillar fossa, (3) diathermy, or (4) partial intracapsular tonsillectomy (PIT)...

We conducted a prospective, randomized, double-blind, controlled clinical study to compare the efficacy and safety of the PlasmaBlade device and cold dissection for adult tonsillectomy. Our study group was made up of 20 patients-12 men and 8 women, aged 18 to 50 years (mean: 27.1)-who were undergoing a bilateral tonsillectomy. Each patient had one randomly chosen tonsil removed by the PlasmaBlade and the other by cold instrumentation. We compared the duration of surgery, the amount of intraoperative blood loss, the number of sutures required, the status of tonsillar fossa wound healing at 7 and 14 days postoperatively, the amount of postoperative pain, and postoperative complications...

BACKGROUND: Infections with Schistosoma mansoni and soil-transmitted helminthes (STHs) are major public health problems in Ethiopia. However, information was scarce on the current status of these infections to guide an intervention in the study area. Therefore, this study was conducted to assess the prevalence of infections with S. mansoni and STHs and associated factors among school children in southern Ethiopia. METHODS: This cross-sectional study investigated children who were attending the Finchawa and Tullo junior elementary schools and were residing along the shore of the lake Hawassa in January and February, 2015...

One of the fundamental patterns in macroecology is the increase in the number of observed taxa with size of sampled area. For microbes, the shape of this relationship remains less clear. The current study assessed the diversity of aquatic fungi, by the traditional approach based on conidial morphology (captures reproducing aquatic hyphomycetes) and next generation sequencing (NGS; captures other fungi as well), on graded sizes of alder leaves (0.6 to 13.6 cm2). Leaves were submerged in two streams in geographically distant locations: the Oliveira Stream in Portugal and the Boss Brook in Canada...
