The Nuclear Factor-kB RelA Transcription Factor Is Constitutively Activated in Human Pancreatic Adenocarcinoma Cells

Pancreatic adenocarcinoma is a leading cause of adult cancer mortality in the United States. Recent studies have revealed that point mutation of the K-ras oncogene is a common event in pancreatic cancer, and oncogenesis mediated by Ras may also involve activation of Rel/nuclear factor (NF)-kB transcription factors. Furthermore, the c-rel member of Rel/NF-kB transcription factor family was first identified as a cellular homologue of the vrel oncogene, suggesting that other members of the Rel/NF-kB family are potentially oncogenes. We therefore investigated the possibility that Rel/NFkB transcription factors are activated in pancreatic cancer. Immunohistochemical analysis, Western blot and Northern blot analysis, electrophoretic mobility shift assays, and chloramphenicol acetyltransferase assays were performed to determine RelA activity in human pancreatic adenocarcinomas and normal tissues and nontumorigenic or tumorigenic cell lines. RelA, the p65 subunit of NF-kB, was constitutively activated in;67% (16 of 24) of pancreatic adenocarcinomas but not in normal pancreatic tissues. Constitutive RelA activity was also detected in 9 of 11 human pancreatic tumor cell lines but not in nontumorigenic Syrian golden hamster cell lines.IkBa, a previously identified NF-kB-inducible gene, was overexpressed in human pancreatic tumor tissues and cell lines, and RelA activation could be inhibited by curcumin and dominant-negative mutants of IkBa, raf, and MEKK1. This is the first report demonstrating constitutive activation of RelA in nonlymphoid human cancer. These data are consistent with the possibility that RelA is constitutively activated by the upstream signaling pathway involving Ras and mitogen-activated protein kinases in pancreatic tumor cells. Constitutive RelA activity may play a key role in pancreatic tumorigenesis through activation of its downstream target genes.
Light and Electron Microscopy of Bone Marrow Hemo- poiesis in Late Embryonal and Early Postnatal Mice: A Qualitative and Quantitative Study*

Using serial sections of the entire body of late embryonal and early postnatal mice, a morphologic analysis of the bone marrow in the whole skeleton was made qualitatively and quantitatively. Hemopoietic cells in the developing marrow were also examined at the light and electron microscopic levels. Before birth, the bone marrow is quite small in volume. During the first five postnatal days, the marrow shows an approximately 65-fold increase in total volume. At 0-3 days of age, hemopoiesis begins in the marrow throughout the body. Marrow hemopoiesis starts earlier in the rib, scapula, humerus and femur. The development of hemopoiesis proceeds through the following three stages: 1) formation of the marrow cavity, 2) accumulation of neutrophils in the cavity, and 3) appearance of hemopoietic cells. In the bone marrow prior to active hemopoiesis, a majority of cells first appearing are mature neutrophils, among which immature erythroblasts and dark small lymphocytes, although very small in number, are seen. The functional significance of the cells appearing early is discussed in relation to the sequent events involved in marrow hemopoiesis. In addition to the marrow, development of the other blood forming tissues and lymphatic organs is also examined quantitative-morphologically.

This study follows post positivism philosophy, a deductive approach and quantitative research method. A questionnaire was used to collect data from 393 restaurants customers. Path analysis is employed to test the research hypotheses using Smart PLS 0.3 . The results have confirmed that restaurant innovativeness is positively related to revisit intention.
Hand Washing: When Ritual Behavior Protects! Obsessive–Compulsive Symptoms in Young People during the COVID-19 Pandemic: A Narrative Review

The Coronavirus Disease 2019 (COVID-19) pandemic had a profound impact on the lifestyles and mental health of young people. It has been hypothesized that the focus on hygiene and the fear of contamination/infection during the pandemic may have exacerbated obsessive–compulsive (OC) symptoms in this population. OC symptoms are widespread in the general population, with varying degrees of intensity. At their most extreme, they manifest in obsessive–compulsive disorder (OCD), which is characterized by obsessive thoughts and compulsive behaviors. The present narrative review aimed at evaluating the relationship between the COVID-19 pandemic and OCD and OC symptoms in young people, especially children and adolescents with and without OCD, focusing on vulnerability and risk factors and the impact of lockdown measures. Of the six studies identified, four examined clinical samples diagnosed with OCD and two looked at community-based adolescent samples. Five of the six studies found that OC symptoms increased during the pandemic. Additionally, vulnerability to anxiety may constitute a risk condition and the lockdown measures and personal stressful life events can constitute potential triggers of OC symptoms, while ongoing treatment for OCD had a protective effect. The results suggest that, during the COVID-19 pandemic, obsessive and compulsive behavior (e.g., hand washing) in young people at the greatest risk should be monitored, and the intervention of mental health services should be maintained. More research is needed in this area.
Changes in Ovarian Expression Activator and Plasminogen Act Messenger Ribonucleic Acids d of Tissue-Type Plasminogen ivator Inhibitor Type-1 uring Ovulation in Rat

We investigated the time course and localization of ovarian tissue-type plasminogen activator (tPA) and plasminogen activator inhibitor type-1(PAI-1) expression during the ovulatory period in rat by RNase protection assay and in situ hybridization. Immature female Wistar rats were injected with 25 IU pregnant mare serum gonadotropin (PMSG), followed 50 h later by 25 IU human chorionic gonadotropin (hCG). Levels of tPA mRNA were low before hormone treatment and after PMSG treatment. After hCG treatment, tPA mRNA levels increased rapidly, the first peak at 4 h after hCG treatment and reached a maximum just prior to ovulation, l2 h later, before declining again. PAI-1 mRNA was barely detectable before hormone treatment but was transiently induced by hCG treatment, reaching peak levels after 4 h. Subsequently, PAI-1 mRNA levels decreased until early luteinization. The expression of tPA mRNA 4 h after hCG treatment occurred mainly in the follicular thecal-interstitial cells, but was barely detectable in the granulosa cells, whereas 12 h after hCG treatment it was maximal in the granulosa cells of the large follicles destined to ovulate. PAI-1 mRNA was expressed mainly in ovarian stromal tissue and in the thecal external interstitial cells encapsulating the follicles at 4 h after hCG treatment. These results suggest that the temporal regulation of tPA biosynthesis after hCG induction depends on the cell types and size classes in the various ovarian compartments. PAI-1 may be produced by the stormal tissue and the thecal external interstitial cells and is perhaps implicated in structural changes during follicular growth, ovulation and luteinization.
Li 2 TiO 3 /Graphene and Li 2 TiO 3 /CNT Composites as Anodes for High Power Li-Ion Batteries

Three-dimensional composites Li2TiO3/graphene (LTO/Gr) and Li2TiO3/carbon nanotube (LTO/CNTs) were synthesized by solid-state reaction for application as anode materials for lithium-ion batteries. These composites are structurally characterized by X-ray diffraction, Raman spectroscopy and high-resolution transmission electron microscopy, while electrochemically tests are performed by cyclic voltammetry and chronopotentiometry. The synergetic effect of graphene and CNTs with LTO facilitate the network conduction leading to faster electron and Li ion transfer and improve cycling stability and rate capability of the anode. The LTO/Gr and LTO/CNTs composites exhibited an initial discharge capacity as high as 154 and 149 mAh g at 1C rate, respectively and retained excellent cycling stability of 98% and 96% after 30 charge–discharge cycles.
Moving across Borders: The Work Life Experiences of Czech Cross‐border Workers during the COVID‐19 Pandemic

Abstract The experiences of cross‐border workers (CBWs) and the difficulties they face during the ongoing COVID‐19 pandemic have been neglected in previous research. CBWs experience various stressors under normal circumstances, where they are often subjected to unequal working conditions and forced to transition between two different societies. The measures that were introduced in response to the COVID‐19 pandemic, including the implementation of physical borders, further worsened the situation for these individuals. Herein, we draw on qualitative interview data from 35 CBWs from the Czech Republic and Germany to explore their experiences of work, stress, support, and their positioning in society during the pandemic. We detail the dissatisfaction felt by CBWs regarding re‐bordering, the lack of coordination in the crisis management, and the lack of support from national governments and the EU. This study provides unique insights into the difficulties and experiences of CBWs in a time of crisis.
Comparative study of aerodynamic behaviour of three flow conditioners

Accuracy and precision of flow meters are the most important metrological parameters in most industries dealing with increasingly expensive fluids. The accuracy of these devices depends not only on their construction and method of operation but also of their position in the pipe network. Pipe fittings such valve, bends and other fixtures generate turbulence and swirl and distort the flow distribution in the pipe. The present paper is concerned with an experimental study of the decay process of highly swirling flow in a circular pipe and its effect on orifice flow meter reading. The efficiency of three flow conditioners (The Etoile and the Tube bundle straighteners described in the Standards ISO 5167 and the Laws perforated plate) to remove swirl and to reduce metering errors has been investigated using a two components Laser Doppler Anemometer. Highly swirling flow distortion was generated by a 90° out of planes double bend upstream the flow meter. Discharge coefficient shifts due to the flow distortion was determined for three orifice meters with a diameter ratio □=0.5, 0.62 and 0.70 at flow Reynolds number ranging from 0.79 to 3.21x10 5 . The results show that the disturbance causes important deviations in the meter's calibration coefficient. The effectiveness of the flow conditioning devices to remove the flow distortion and to reduce the resulting metering error was not evident for all the working conditions studied here.
Check the Report and Comments: The Veracity Assessment of Unfamiliar News on Social Media

Abstract Given growing concerns regarding the spread of medical misinformation, the current research set out to assess the message effects of social media news on reader veracity assessments. A 2 (news report with hedging vs. without hedging) by 3 (uncivil vs. civil vs. no comments) between-subject experiment on Facebook users was conducted (valid N = 824). Results reveal that news hedging was more predictive of perceived credibility, news sharing, and fact-checking tendencies than was comment incivility. Hedged reporting was also found to elevate perceived news credibility, which in turn predicted a greater likelihood of news sharing. Moreover, perceived credibility increased fact-checking tendency only when the news was reported with hedged messages. These findings indicate that when readers encounter an unfamiliar health news issue, the content of news played a more important role in veracity assessment than the style of reader comments.

To reveal the preconditions and factors like innovative management, service quality, digital marketing, and supply chain management that enable cultural tourism performance in Thailand's northeast, a survey was done utilizing a questionnaire and a simple random approach with key informants such as tourists. The findings imply that encouraging performance is dependent on innovative management, service quality, digital marketing, and supply chain management in cultural tourism.
Exploring Cultural Bias in Two Different Motor Competence Test Batteries When Used in African Children

Both the Movement Assessment Battery for Children second edition (M-ABC-2) and Bruininks-Oseretsky Test of Motor Proficiency second edition short form (BOT-2-SF) are frequently used in research and in the clinical practice to evaluate motor competence in children. Despite its widespread use in research, no studies have reported the results of case identification in African children. Comparing these two motor assessment tools for a different target group is important in order to select the most appropriate clinical and research tool. Methods. A total of 444 children performed MABC-2, 165 children also performed the BOT-2-SF and subsamples were tested on specific subtests of the BOT-2 (Running and Agility, Balance, and Strength). Tests were administered to randomly selected children between 6 and 10 years of age. Results: 36% for the children scored at or below the 16th percentile of the MABC-2, while this was 43%, 27%, and 23% for the component score in Manual Dexterity, Aiming and Catching, and Balance, respectively. Of the children 16% scored at or below the 17th percentile of the BOT-2-SF total score, while this was 3%, 9% and 22% for the subtest scores Running and agility, Balance, and Strength, respectively. A moderate correlation (r = 0.44) was found between total scores of the two tests. No significant correlations were found between the dynamic MABC-2 item (Jumping/Hopping) standard scores and any of the 9 balance items of the BOT-2. Conclusion: Far more children scored in the clinical “at risk” range (<16th percentile) when tested with the MABC-2 than with the BOT-2-SF. Overall, these children seemed not to be limited in motor performance measured by the BOT-2-SF, Running and Agility, and Balance. South African children did show lower levels of strength and explosive power. Children from different cultures will need tests for the specific motor skills that are representative for optimal functioning in their own setting. Thus, adapting reference norms and cut-off values may not be the optimal solution.
Open Reduction of the Dislocated, Fractured Condylar Process: Indications and Surgical Procedures

The subject of this paper is the evaluation of the results after surgical management of 29 dislocafed fractures of the condylar process. Only frac­ tures with total dislocation of the condyle out of the articulate fossa were surgically treated. The surgical procedure, making a broad exposure nec­ essary, is detailed. The low rate of complications as well as the satisfactory function of the joints in spite of severe dislocation seems to confirm the surgical treatment of this type of fractures.
The Critical Factors Impacting Artificial Intelligence Applications Adoption in Vietnam: A Structural Equation Modeling Analysis

The concept of artificial intelligence (AI) is the transformation of inanimate objects into intelligent beings that can reason similarly to humans. Computer systems are capable of imitating a number of human intelligence functions, such as learning, reasoning, problem solving, speech recognition, and planning. In this regard, artificial intelligence applications have been developed to assist corporations and entrepreneurs in making business decisions. Hence, the aim of the study is to investigate the adoption of AI applications at the Vietnamese organizational level. Using the core structures of the technology–organization–environment (TOE), the theoretical model was constructed based on how technical and environmental elements influence companies’ technological innovation adoption decisions. Ten critical factors related to AI adoption are identified. To test the model, data were obtained from 193 senior managers who are directly in charge of information systems in both private and public companies in Vietnam. Subsequently, the Structural Equation Modeling (SEM) approach was used to analyze the data. The findings indicate that technical compatibility, relative advantage, technical complexity, technical capability, managerial capability, organizational readiness, government involvement, market uncertainty, and vendor partnership are significantly related to AI application adoption. Interestingly, the study results indicated that the relationship between organization size and AI adoption was not statistically significant. Therefore, the suggested adoption of the AI application could contribute to the existing research on the adoption of AI through the TOE. Finally, the significant government law implications and future research directions are further addressed.
Serum CXCL5 as a biomarker in multiple sclerosis and neuromyelitis optica spectrum disorder

OBJECTIVE Our aim was to determine whether serum C-X-C motif chemokine 5 (CXCL5) may serve as a diagnostic biomarker for relapsing-remitting multiple sclerosis (RRMS) as well as a marker that can be used to predict treatment response. METHODS CXCL5 levels were measured by ELISA in sera of 20 RRMS patients under fingolimod treatment, 10 neuromyelitis optica spectrum disorder (NMOSD) patients, 15 RRMS patients presenting predominantly with spinal cord and optic nerve attacks (MS-SCON), and 14 healthy controls. RESULTS Fingolimod treatment significantly reduced CXCL5 levels. CXCL5 levels were comparable among NMOSD and MS-SCON patients. CONCLUSION Fingolimod might regulate the innate immune system. Serum CXCL5 measurement does not differentiate between RRMS and NMOSD.
Exploring inequities in housing affordability through an analysis of walkability and house prices by neighbourhood socioeconomic disadvantage

ABSTRACT Cities are socio-spatially patterned, yet few researchers have explored the association between walkability and house prices by neighbourhood socioeconomic disadvantage, highlighting issues about housing affordability, equity, and liveability. We aimed to determine whether walkability and house prices differed by neighbourhood socioeconomic disadvantage. To test this, we used linear regression models of house prices stratified by quintiles of neighbourhood socioeconomic disadvantage at the suburb level in metropolitan Melbourne, Australia on walkability and its components (street connectivity, dwelling density, and destination access), and public transit access. Walkability was positively associated with house prices. In the stratified regressions, destination accessibility was associated with higher house prices whilst having poor access to transit was negatively associated with house prices. The association between walkability and house prices was weakest for the most disadvantaged areas, suggesting that houses in these areas were more affordable due, in part, to a lack of amenity. Future planning could redress the relationship between walkability and house prices by making new areas walkable. Increasing densities in outer suburban areas would improve destination and transit access, and in established areas, inclusionary zoning policies could help ensure accessibility to social and affordable housing in amenity-rich areas redressing built environment inequities.
The Burden of a Violent Past: Formative Experiences of Repression and Support for Secession in Catalonia

Abstract This letter studies the impact of past violence and repression on current territorial preferences in a contemporary democracy. Does a violent past lay the grounds for pro-secessionist preferences, or does it lead individuals to cling on to the territorial status quo? We study whether exposure to the events of the Spanish Civil War and its immediate aftermath made people more or less likely to support Catalan secession from Spain. Our analysis employs a dataset that combines a large N of individual-level survey data with historical data about repression and violence in each Catalan municipality. Findings indicate that current preferences for secession tend to diminish among the oldest Catalan generation that was exposed to higher levels of violence in their municipality. Most crucially, we show that exposure to violence created a sense of apathy towards politics among the oldest cohort, which eventually leads to a lower predisposition to support secession, a feeling that was not transmitted to subsequent generations. Our findings qualify some of the existing knowledge on the effects of past political violence on present political attitudes.
High-Tc Superconducting Microwave and Millimeter Devices and Circuits—An Overview

High temperature (high-Tc) superconductors (HTS) have found many applications in the last two decades. To microwave researchers and engineers, the ultra-low surface resistance of the thin-film HTS materials at microwave and millimeter frequencies and the highly non-linear Josephson junctions are of particular interest. The former can be exploited in the design and fabrication of passive microwave components and circuits with superior performance, and the latter can be exploited to create many novel active HTS devices. This paper provides an overview of the state-of-art development of HTS devices and circuits for microwave and mm-wave communication front-end receiver systems. The paper is particularly focused on the latest advancement of HTS Josephson junction based active devices, monolithic microwave integrated circuits (MMIC), and whole receiver systems integrated with cryocoolers.
