[Pancreatic Panniculitis in Patients with Chronic Pancreatitis: Case Report and Review of Literature].

Pancreatic panniculitis is a rare complication characterized by subcutaneous fat necrosis associated with pancreatic disease. It has been postulated that pancreatic panniculitis is caused by the systemic activity of pancreatic enzymes that lead to microcirculatory disturbances. We report a 41-year-old heavy alcoholic woman with pancreatic panniculitis that coexisted with acute and chronic pancreatitis.

First childbirth experience of international marriage migrant women in South Korea.

Problem And Background: Since the mid-1990s, a large number of foreign women have migrated from developing countries to South Korea by means of international marriages. These nulliparous foreign women may experience more difficulties in pregnancy and childbirth than native Koreans.

Aim: This study aimed to describe the meaning of the first childbirth experiences of international marriage migrant women marrying Korean men in South Korea.

Multiple Pyogenic Liver Abscesses Caused by Microperforation of an Idiopathic Cecal Ulcer.

Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain.

The cultural context of teaching and learning sexual health care examinations in Japan: a mixed methods case study assessing the use of standardized patient instructors among Japanese family physician trainees of the Shizuoka Family Medicine Program.

Background: In contrast to many western nations where family medicine is a cornerstone of the primary care workforce, in Japan the specialty is still developing. A number of services within the bailiwick of family medicine have yet to be fully incorporated into Japanese family medicine training programs, especially those associated with sexual health. This gap constitutes a lost opportunity for addressing sexual health-related conditions, including cancer prevention, diagnosis, and treatment.

[A Case of Paradoxical Reaction Development during Antituberculosis Therapy].

Paradoxical reaction during antituberculosis therapy is defined as aggravation of preexisting tuberculous lesions or the development of new lesions. A 24-year-old female college student diagnosed with abdominal and pulmonary tuberculosis presented with fever and abdominal pain after having been treated with antituberculosis agents for 4 months. Tuberculous mesenteric lymphadenitis was suspected on abdominal CT scan and enlarged necrotic abscess was also present.

Tissue inhibitor of metalloproteinase-1 is responsible for residual pleural thickening in pleural tuberculosis.

Residual pleural thickening (RPT) is the most frequent complication associated with pleural tuberculosis, and may occur even after successful anti-tuberculosis medications. Matrix metalloproteinases (MMPs) are zinc-dependent proteinases capable of degrading all components of the extracellular matrix. The proteolytic action of MMPs may be involved in the pathogenesis of tuberculosis.

Involvement of Notch1 inhibition in serum-stimulated glia and oligodendrocyte differentiation from human mesenchymal stem cells.

The use of in vitro oligodendrocyte differentiation for transplantation of stem cells to treat demyelinating diseases is an important consideration. In this study, we investigated the effects of serum on glia and oligodendrocyte differentiation from human mesenchymal stem cells (KP-hMSCs). We found that serum deprivation resulted in a reversible downregulation of glial- and oligodendrocyte-specific markers.

Reduced critical rotation for resistive-wall mode stabilization in a near-axisymmetric configuration.

Recent DIII-D experiments with reduced neutral beam torque and minimum nonaxisymmetric perturbations of the magnetic field show a significant reduction of the toroidal plasma rotation required for the stabilization of the resistive-wall mode (RWM) below the threshold values observed in experiments that apply nonaxisymmetric magnetic fields to slow the plasma rotation. A toroidal rotation frequency of less than 10 krad/s at the q=2 surface (measured with charge exchange recombination spectroscopy using C VI) corresponding to 0.3% of the inverse of the toroidal Alfvén time is sufficient to sustain the plasma pressure above the ideal MHD no-wall stability limit.

Lithium administration to preadolescent rats causes long-lasting increases in anxiety-like behavior and has molecular consequences.

Lithium (Li) is frequently used in the treatment of bipolar disorder (BPD), a debilitating condition that is increasingly diagnosed in children and adolescents. Because the symptoms of BPD in children are different from the typical symptoms in adulthood and have significant overlap with other childhood psychiatric disorders, this disorder is notoriously difficult to diagnose. This raises the possibility that some children not affected by BPD are treated with Li during key periods of brain development.

Rotational stabilization of resistive wall modes by the shear alfvén resonance.

It is found that resistive wall modes with a toroidal number n = 1 in tokamaks can be stabilized by plasma rotation at a low Mach number, with the rotation frequency being lower than the ion bounce frequency but larger than the ion and electron precession drift frequencies. The stabilization is the result of the shear-Alfvén resonance, since the thermal resonance effect is negligible in this rotation frequency range. This indicates that tokamaks can operate at normalized pressure values beyond the no-wall stability limit even for low values of plasma rotation, such as those expected in fusion reactor scale devices.

Signalling pathway in the induction of neurite outgrowth in human mesenchymal stem cells.

Recent in vivo transplantation studies have shown that mesenchymal stem cells (MSCs) were able to differentiate into mesoderm-derived cell types as well as cells with neuroectodermal characteristics, suggesting that transdifferentiation occurs in the mammalian system. We have reported an immortalized line of human MSCs (hMSCs), KP-hMSCs, which expresses CD29, CD44, CD90, and CD105, and complies with the characteristics shared by mere hMSCs. In a current experiment, we further demonstrated that expanded KP-hMSCs exhibited markers of neuroepithelial or neural precursor cells, such as Nestin, Musashi-1, Vimentin, NCAM, Pax-6, and Sox-9.

Thermal insulation and SIDS-an investigation of selected 'Eastern' and 'Western' infant bedding combinations.

Background: Differences in the incidence of SIDS between 'Western' and 'Eastern' countries has been attributed to cultural practices, which may affect the infants care and thermal environment.

Aim: The purpose of this work was to estimate for selected 'commonly' used bedding, sleep positions and practices in Japan, Korea and New Zealand, the intrinsic 'dry' thermal resistance of bedding. Insulation levels are also discussed in the context of published information about the thermal environment in which the bedding is likely to be used.

Measurement of the resistive-wall-mode stability in a rotating plasma using active MHD spectroscopy.

The stability of the resistive-wall mode (RWM) in DIII-D plasmas above the conventional pressure limit, where toroidal plasma rotation in the order of a few percent of the Alfve n velocity is sufficient to stabilize the n=1 RWM, has been probed using the technique of active MHD spectroscopy at frequencies of a few Hertz. The measured frequency spectrum of the plasma response to externally applied rotating resonant magnetic fields is well described by a single-mode approach and provides an absolute measurement of the damping rate and the natural mode rotation frequency of the stable RWM.

[Effects of pituitary adenylate cyclase activating polypeptide (PACAP) on intracellular cAMP and Ca(2+) levels in common carp (Cyprinus carpio) pituitary cells in vitro].

In order to study signal transduction in PACAP-stimulated GH release, effects of ovine PACAPs (oPACAPs) on cAMP synthesis and intracellular free Ca(2+)([Ca(2+)](i)) levels in primarily cultured common carp (Cyprinus carpio) pituitary cells were investigated using radioimmunoassay (RIA) for cAMP and [Ca(2+)](i) Indo-1/AM loading techniques. The main results obtained could be briefly summarized as follows: parallel with their GH-releasing effects, oPACAP-38 (0.01 nmol/L to 1 micromol/L) and oPACAP-27 (0.

Internal kink instability during off-axis electron cyclotron current drive in the DIII-D tokamak.

Experimental evidence is reported of an internal kink instability driven by a new mechanism: barely trapped suprathermal electrons produced by off-axis electron cyclotron heating on the DIII-D tokamak. It occurs in plasmas with an evolving safety factor profile q(r) when q(min) approaches 1. This instability is most active when ECCD is applied on the high field side of the flux surface.
