BACKGROUND/AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is typically performed in prone position. In cases of difficulty in prone position, ERCP can be performed in left lateral position. We aimed to evaluate the efficacy and safety of left lateral position for ERCP compared with those of prone position. PATIENTS AND METHODS: Between August 2015 and March 2016, a total of 62 patients with native papilla who underwent ERCP were randomly assigned to undergo the procedure in left lateral position (n = 31) or prone position (n = 31)...

We measured the auditory sensitivity of the barn owl (Tyto alba), using a behavioural Go/NoGo paradigm in two different age groups, one younger than 2 years (n = 4) and another more than 13 years of age (n = 3). In addition, we obtained thresholds from one individual aged 23 years, three times during its lifetime. For computing audiograms, we presented test frequencies of between 0.5 and 12 kHz, covering the hearing range of the barn owl. Average thresholds in quiet were below 0 dB sound pressure level (SPL) for frequencies between 1 and 10 kHz...

We apply new perspectives on how organisms burrow by examining the association of in situ variation in sediment mechanical properties with burrowing ability and species distribution of two sympatric lugworms, Abarenicola pacifica and Abarenicola claparedi We quantified the sediment's resistance to penetration and its grain size distribution at sites inhabited by each species. Abarenicola pacifica individuals were found in significantly harder to penetrate, more heterogeneous sediments. We compared worm burrowing ability using reciprocal transplant experiments...

Teneurins are transmembrane proteins consisting of four paralogues (Ten-1-4), notably expressed in the central nervous system during development. All teneurins contain a bioactive peptide in their carboxyl terminal named teneurin C-terminal associated peptide (TCAP). The present study analyzed the detailed distribution of teneurin-2-like immunoreactive (Ten-2-LI) cells in developing and mature rat molar teeth, as well as in mature human dental pulps. Ten-2 and TCAP-2 genic expressions were also evaluated in rat and human dental pulps...

The canonical Wnt/β-catenin signaling pathway has been shown to play essential roles in tooth initiation and early tooth development. However, the role of Wnt/β-catenin signaling in cusp patterning and crown calcification in large mammals are largely unknown. In our previous study, miniature pigs were used as the animal model due to the similarity of tooth anatomy and replacement pattern between miniature pig and human. Dynamic gene expression of third deciduous molar (DM3) in miniature pig at early stages was profiled using microarray method and expression of Wnt genes was significantly correlate with odontogenesis...

The yellow fever mosquito, Aedes aegypti, has three genes that code for proteins with sequence similarity to vertebrate Na(+)-K(+)-Cl(-) cotransporters (NKCCs) of the solute-linked carrier 12 superfamily of cation-chloride cotransporters (CCCs). We hypothesized that these mosquito NKCC orthologues have diverged to perform distinct roles in salt secretion and absorption. In phylogenetic analyses, one protein (aeNKCC1) groups with a Drosophila melanogaster NKCC that mediates salt secretion whereas two others (aeCCC2 and aeCCC3) group with a Drosophila transporter that is not functionally characterized...

BACKGROUND: Wire-guided cannulation has been widely accepted as a useful technique for achieving selective biliary access because it has significantly increased the success rate of biliary cannulation compared with conventional contrast-assisted cannulation. Unlike conventional guidewires with a straight tip, a loop-tip guidewire (LGW) has a closed distal loop that may facilitate less traumatic access through the epithelial folds of the intra-duodenal biliary segments. The aim of this study was to compare the performance of a LGW with a straight-tip guidewire (SGW) in achieving successful selective biliary cannulation...

Dermal papilla cells (DPCs) are important components of hair follicles and play a critical role in hair follicle development. However, the mechanisms by which DPCs induce hair follicle development remain unclear. In the present study, we identified the mitotic arrest deficient protein MAD2B as a modifier of DPCs. Overexpression of MAD2B inhibited DPC aggregative growth and proliferation induced by the Wnt signaling activator T cell factor 4 (TCF4), and decreased TCF4-induced expression and the release of hair growth-related cytokines, including hepatocyte growth factor, insulin-like growth factor-1, and vascular endothelial growth factor in DPCs...

Human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced PSCs (iPSCs), represent potentially unlimited cell sources for clinical applications. Previous studies have suggested that hPSCs may benefit from immune privilege and limited immunogenicity, as reflected by the reduced expression of major histocompatibility complex class-related molecules. Here we investigated the global immune-related gene expression profiles of human ESCs, hiPSCs and somatic cells and identified candidate immune-related genes that may alter their immunogenicity...

While the myth of the tongue map has been consistently and repeatedly debunked in controlled studies, evidence for regional differences in suprathreshold intensity has been noted by multiple research groups. Given differences in physiology between the anterior and posterior tongue (fungiform versus foliate and circumvallate papillae) and differences in total area stimulated (anterior only versus whole tongue, pharynx, and epiglottis), small methodological changes (sip and spit versus sip and swallow) have the potential to substantially influence data...

Beyond sexual functions, androgens exert their action in skin physiology and pathophysiology. Skin cells are able to synthesize most of active androgens from gonadal or adrenal precursors and the enzymes involved in skin steroidogenesis are implicated both in normal or pathological processes. Even when the role of androgens and androgen receptor (AR) in skin pathologies has been studied for decades, their molecular mechanisms in skin disorders remain largely unknown. Here, we go over recent studies of androgens and AR roles in several skin-related disorders, focusing in the current understanding of its molecular mechanisms in androgenetic alopecia (AGA)...

Lichen amyloidosis (LA) is characterized by the deposition of amyloid that may respond to chronic scratching that may be secondary to atopic dermatitis, stasis dermatitis, or interface dermatitis. Despite the development of several therapeutic strategies, including topical steroids, oral antihistamines, cyclosporine, and retinoids, an effective treatment for LA has not been established. A 49-year-old woman who has been treated irregularly for atopic dermatitis for 7 years presented with localized brownish papules on the left forearm and right elbow...

The genus Oliveiriella (Chironomidae, Orthocladiinae) was erected by Wiedenbrug & Fittkau (1997). The adults have characteristic black spots on their wings and other characteristics similar to the genus Cricotopus. Pupal skins are very characteristic with strong short spines in the anal lobe instead of setae, while larvae are distinguishable by the long anal papillae and the intense blue color of their body. However, Andersen et al (2013) consider Oliveiriella as a subgenera of Cricotopus. In this paper, using the sequences of the cox1 gene, we conclude that Oliveiriella should be considered a subgenus within Cricotopus, confirming its status in Andersen et al (2013)...

BACKGROUND: The reclassification of noninvasive follicular variant of papillary thyroid carcinoma as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) has created diagnostic and management issues for thyroid fine-needle aspiration (FNA). In response to these challenges, the authors' laboratory adopted a NIFTP policy including 1) stringent criteria (requiring pseudo-inclusions, papillae, and/or psammoma bodies) for a malignant diagnosis of papillary carcinoma to limit false-positive results due to NIFTP and 2) the use of explanatory notes in cases with cytomorphologic features suggestive of possible NIFTP to encourage lobectomy over thyroidectomy...

Mesenchymal stem cells (MSCs) in teeth have been exploited as vital seed cells for stem cell-based dental medicine. To date, several mesenchymal stem cell populations originated from odontogenic tissue have been isolated and characterized by their expression of MSC surface markers and capacity of multi-lineage differentiation, including dental pulp stem cells (DPSCs), stem cells from human exfoliated deciduous teeth (SHED), stem cells from apical papilla (SCAP) and so on. However, their identity in vivo remains elusive, which hinders further understanding of their application in stem cell-based tooth regeneration...

Riley-Day syndrome is an autosomal recessive sensory and autonomic neuropathy. Patients present a lack of fungiform papilla, alacrima and usually feeding difficulties. It is present almost exclusively in Ashkenazi Jewish individuals and has a poor prognosis. We describe an unusual case of Riley-Day syndrome with pseudostrabismus in a non-Ashkenazi Jewish patient. A one-year-old female infant was referred for evaluation of strabismus, absence of fungiform papillae, feeding difficulty, gastroesophageal reflux and episodes of self-mutilation...
