METHODS |
An animal model of acute pancreatitis was established, in which rats in the experimental group were given intraperitoneal (IP) injections of caerulein. Before the rats were sacrificed, 5-bromo-2'-deoxyuridine (BrdU) was administered by IP injection to label proliferating pancreatic cells. The localization and distribut... |
RESULTS |
(1) The nestin-positive cells first appeared in the pancreatic interlobar vessels, and then, were observed in the pancreatic acinar and islet tissues. (2) C-kit-positive cells were located only in the pancreatic islets. (3) BrdU-positive cells first appeared in the area surrounding the interlobular region, and then wer... |
CONCLUSIONS |
(1) The stem cells, participated in the repair of damaged pancreatic tissue, appear firstly in the pancreatic interlobar vessels, then migrate toward the pancreatic lobules by using the interlobar vessels as channels and penetrate through the vascular endothelium into the pancreatic acinar tissues. A portion of the ste... |
Despite an initially warm reception, over the past two centuries assessments of the literary character of Adam Smith’s The Wealth of Nations have gradually but unmistakably turned negative. This transformation in the public reception of Smith’s text began during his lifetime and culminated in Heilbroner’s assertion tha... |
Universities have critical role as sources of intellectual property and talent in regional development and high technology industries. We present a theoretical framework based on social capital and knowledge management literatures describing the knowledge generation and transfer processes for universities. Our research... |
Using a collective case study approach, this study explored a phenomenon called compulsory heterogenderism, a neologism created to explain the ways in which gender identities and sexualities are consistently understood in and through each other. Put another way, although participants’ sexualities (e.g., being gay, lesb... |
A possible benefit of creating smaller and more rigid active analogs of somatostatin is the discovery of compounds which selectively inhibit the secretion of insulin, glucagon or growth hormone. A series of cyclic tetrapeptide analogs related to somatostatin was synthesized, and one member of this series was found to c... |
Many inflammatory factors can affect cell behaviors and work as a form of inter‐regulatory networks through the inflammatory pathway. Inflammatory cytokines are critical for triggering bone regeneration after fracture or bone injury. Also, inflammatory cytokines play an important role in cartilage repair. The synergist... |
A microscopic set-up to observe fast moving solidifying particles during stir casting is described.

In Part 2 details about the knowledge of the particular methods revealed by the sources are discussed. As in Part 1, descriptions ... |
Bile acids act as signaling molecules that regulate immune homeostasis, including the differentiation of CD4+ T cells into distinct T cell subsets. The bile acid metabolite isoallolithocholic acid (isoalloLCA) enhances the differentiation of anti-inflammatory regulatory T cells (Treg cells) by facilitating the formatio... |
Since the latter part of the twentieth century, the subject of climate change has been on the agenda of governing bodies from supranational bodies such as the United Nations and the European Union to grassroots groups at the domestic and local levels worldwide, and in the United States. The issue is polarizing, and has... |
Two collected micro-orifice uniform deposit impactors (MOUDIs) and a filter-based sampler were used to measure the size distribution and chemical composition of atmospheric particulate matter at Bakersfield, CA, between January 14 and 23, 1999. The peak number concentration of airborne ultrafine particles measured was ... |
This article illustrates how multifrequency radar observations can refine the mass–size parameterization of frozen hydrometeors in scattering models and improve the correlation between the radar observations and in situ measurements of microphysical properties of ice and snow.

Infants born prematurely are particularly susceptible to respiratory illness due to underdeveloped lungs, which can often result in fatality. Preterm infants in acute stages of respiratory illness typically require mechanical ventilation assistance, and the efficacy of the type of mechanical ventilation and its deliver... |
The American textile industry has lost an estimated 400,000 jobs to offshore competitors since 1980. It is predicted they will lose an additional 600,000 jobs by the year 2002. These losses and their resulting economic threat to the U.S. textile industry can be attributed to the low operating costs of their offshore co... |

ABSTRACT Utilizing a European panel dataset, we contribute to the scant empirical literature on the lawyer-induced litigation hypothesis. To address endogeneity problems that arise when estimating the effect of the number of lawyers on civil litigation rates, we use two strategies. We first estimate our model by means ... |
Modern big and multi-modal datasets often contain corrupted entries or outliers. Standard methods for multi-way/tensor data analysis, relying on L2-norm formulations, are often very sensitive to such dataset corruptions. A new paradigm in data analysis suggests the use of robust L1-norm formulations instead. In this wo... |
Objective: Binocular rivalry refers to a situation where contradictory information is presented simultaneously to the same location of each eye. This leads to the alternation of images every few seconds. The rate of alternation between images has been shown to be slower in euthymic participants with bipolar disorder th... |
Propagation channel characteristics are substantially different in sub-6 GHz and millimeter-wave (mmWave) bands. A typical mmWave link experiences more than an order-of-magnitude larger path loss and is more susceptible to blockages than a traditional sub-6 GHz link. Therefore, extensive measurement campaigns with effi... |
A persistent cloaca, a rare congenital anomaly, is single channel made by confluence of rectum, vagina, urinary tract. Sonographic finding of cloaca including urinary tract malformation with secondary change such as hydronephrosis, hydroureter or dysplastic kidneys, dilated bowel, cystic pelvic mass is very difficult. ... |

Planar heterojunction organic photovoltaics made using a Cl6-SubPc acceptor deliver an exceptionally... |
The old lady cradles her bleeding finger and staggers, feinting almost falling, as Gary from number one sprints back to his garden to pick up a deckchair for her. Her dog, a tiny Yorkshire Terrier, is quivering in another neighbour’s arms, snapping at well-wishers who are trying to inspect the skin for any bite-marks. ... |
We performed both supine bicycle ergometer (BEx) and hand-grip (HGx) exercise tests to evaluate cardiac function in 13 asymptomatic children with leukemia who had completed a general treatment protocol. We calculated fractional shortening (FS), end-systolic stress-volume index (ESS/ESVI), left ventricular diastolic fil... |

The case study offers an insight into the practicalities involved in the use of larvae as ... |
This work presents a comparative study of two different control strategies for a flexible single-link robotic manipulator. The dynamic model of the flexible manipulator involves modeling the rotational base and the flexible link as rigid bodies using Lagrange's method. The resulting system has one rigid Degree-Of-Freed... |
Although the relationship between customer satisfaction and loyalty has been researched extensively, moderating variables on the satisfaction-loyalty link have only received marginal attention, especially in a business-to-business context. In this paper, we adopt the perspective of a two-dimensional model of loyalty. W... |
