Diffusion Of Information

We analyze the design of dynamic menus to sell experience goods. The quality of the product is initially unknown, and the total quantity sold in each period determines the amount of information in the market. We characterize the optimum menu as a function of consumers' beliefs, and the dynamic adjustments resulting from the diffusion of information. The firm faces a dynamic trade-off between gains from trade, information production, and information rents. It initially charges lower prices, sacrificing short-term revenue to increase sales. As more information is revealed, prices increase, and low-valuation buyers are excluded, even when the product's quality is high. (JEL D42, D82, D83, L12)

Contrast Information

Many factors (e.g., resolution of microscope, type of tissue, and preparation of sample) affect electron microscopical images and alter the amount of information that can be retrieved from a specimen. Of interest in this report are those factors associated with the evaluation of epoxy embedded tissues. In this context, informational retrieval is dependant, in part, on the ability to “see” sample detail (e.g., contrast) and, in part, on tue quality of sample preservation. Two aspects of this problem will be discussed: 1) epoxy resins and their effect on image contrast, information retrieval, and sample preservation; and 2) the interaction between some stains commonly used for enhancing contrast and information retrieval.

Summary: The cathartic effect of suicide is traditionally defined as the existence of a rapid, significant, and spontaneous decrease in the depressive symptoms of suicide attempters after the act. This study was designed to investigate short-term variations, following a suicide attempt by self-poisoning, of a number of other variables identified as suicidal risk factors: hopelessness, impulsivity, personality traits, and quality of life. Patients hospitalized less than 24 hours after a deliberate (moderate) overdose were presented with the Montgomery-Asberg Depression and Impulsivity Rating Scales, Hopelessness scale, MMPI and World Health Organization's Quality of Life questionnaire (abbreviated versions). They were also asked to complete the same scales and questionnaires 8 days after discharge. The study involved 39 patients, the average interval between initial and follow-up assessment being 13.5 days. All the scores improved significantly, with the exception of quality of life and three out of the eight personality traits. This finding emphasizes the fact that improvement is not limited to depressive symptoms and enables us to identify the relative importance of each studied variable as a risk factor for attempted suicide. The limitations of the study are discussed as well as in particular the nongeneralizability of the sample and setting.

In this essay, I reflect on my experience of part-time, fixed term, zero-hour, short-term, and unpaid contracts in academia. Precarious contracts are one of the biggest challenges facing our industry as neo-liberal values rule our institutions, impacting our teaching, research, and quality of life.

Hct 116

<P>Background: Despite new agent development and short-term benefits in patients with Colorectal Cancer (CRC), metastatic CRC cure rates have not improved due to high rates of oxaliplatin resistance and toxicity. There is an urgent need for effective tools to prevent and treat CRC and reduce morbidity and mortality of CRC patients. Exploring the effects of bioactive peptides on the antitumor to CRC was of vital importance to the clinical application. </P><P> Objective: This study aimed to investigate the therapeutic impact of Anticancer Bioactive Peptides (ACBP) on anticancer effect of oxaliplatin (LOHP) in human colorectal cancer xenografts models in nude mice. </P><P> Methods: HCT-116 cells were cultured in vitro via CCK-8 assays and the absorbance was measured at 450 nm. Apoptosis and cell cycle were assessed by Flow Cytometry (FCM) in vitro. HCT-116 human colorectal cancer cells inoculated subcutaneously in nude mice of treatment with PBS (GG), ACBP, LOHP, ACBP+LOHP (A+L) in vivo. The quality of life was assessed by dietary amount of nude mice, the weight of nude mice, inhibition rates, tumor weight and tumor volume. Immunohistochemistry and RT-qPCR method was conducted to determine the levels of apoptosisregulating proteins/genes in transplanted tumors. </P><P> Results: ACBP induced substantial reductions in viable cell numbers and apoptosis of HCT116 cells in combined with LOHP in vitro. Compared with the control GG group, ACBP combined low dose oxaliplatin (U) group demonstrated significantly different tumor volume, the rate of apoptosis, the expression levels of Cyt-C, caspase-3,8,9 proteins and corresponding RNAs (P<0.05). The expression of pro-apoptotic proteins in the cytoplasm around the nucleus was significantly enhanced by ACBP. Short term intermittent use of ACBP alone indicted a certain inhibitory effect on tumor growth, and improve the quality of life of tumor bearing nude mice. </P><P> Conclusion: ACBP significantly increased the anti-cancer responses of low dose oxaliplatin (L-LOHP), thus, significantly improving the quality of life of tumor-bearing nude mice.</P>

Bleeding Hemorrhoids

Background: Hemorrhoidal disease is very common in western countries and rectal bleeding is the main symptom complained by patients. Nowadays the ultimate goal of treatment is to block the bleeding with minimally-invasive techniques to minimize post-procedural pain. Objective: The aim of this study is to assess the preliminary results of the emborrhoid technique (embolization of the superior rectal arteries branches) as a new tool for the proctologist to treat severe bleeding hemorrhoids causing anemia. Many categories of patients might benefit from this treatment, such as patients not eligible for conventional surgery, patients not responding to conventional treatment and fit patients with severe bleeding who refused endorectal surgical therapy. Method: From May 2017 to November 2018 a total of 16 patients with chronic rectal bleeding due to hemorrhoids underwent super-selective embolization of the superior rectal arteries at the department of General Surgery in La Spezia, S. Andrea Hospital, Italy. Median age was 59 years. 14 patients were males (87.5 %). Results: No post-procedural and short-term complications were observed at maximum follow up (12 months). The reduction of rectal bleeding with improvement of the quality of life was obtained in 14 patients (87.5%). Conclusion: Our study, although small in number, demonstrates that embolization of superior rectal arteries with coils to treat severe bleeding due to hemorrhoids is safe and effective and does not lead to immediate complications.

Education And Care

The chapter first examines at a conceptual level the links between theories of social investment and childcare expansion. Although ‘the perfect match’ between the two is often taken for granted in the specialized literature as well as in policy papers, it is here argued that a more nuance approach that ‘unpacks’ this relationship is needed. The chapter will then look for elements of variation in early childhood education and care (ECEC) expansion. Despite an increase in spending over the last two decades in many European and Organisation for Economic Co-operation and Development (OECD) countries, wide variation still exists in the way in which ECEC develops. A trade-off is often observed between coverage and quality of provision. A crucial dividing line that determines, to a large extent, the quality of provision in ECEC is the increasing differentiation between preschool education for children aged 3 and above and childcare for younger children.
