SENSORY ACCEPTANCE of JUICE FROM FCOJ PROCESSING STEPS

The acceptance of orange juice from the frozen concentrated orange juice (FCOJ) processing steps was evaluated by 101 consumers for color, overall impression, aroma, flavor and texture. The juice from the extraction, filtration, concentration, cooling and blend steps was collected at the beginning and the end of the 2009 harvest period. The juice from the extraction and filtration steps showed higher acceptance means for overall impression, aroma and flavor, while the juice from the concentration, cooling and blend steps had acceptance lower than the cutoff score. The internal preference mapping showed that color discriminated the juice from the collection periods while texture allowed discrimination between the steps of extraction and of filtration. The acceptance of the orange juice was driven by the aroma and flavor. The sensory acceptance was successfully applied to evaluate change during the process and the difference between the orange juice from different steps of the FCOJ processing.

Innovative winemaking: Consumer acceptance of red table wines

Purpose: This paper aims to evaluate the consumer acceptance of Bord�� and Isabel wines from innovative winemaking in order to increase red wine consumption by consumers to obtain nutritional benefits. Design/methodology/approach: All wines were produced by a standard procedure of vinification. Pre-drying treatment aimed at drying the grapes up to 22��Brix and static pomace wines presented the constant contact between the must and pomace. Sensory acceptance was carried out by 80 consumers who evaluated eight samples (six experimental wines and two commercial wines) concerning the attributes: appearance, aroma, body, flavor and overall acceptance. Findings: Experimental wines presented higher acceptance when compared to commercial wines and cluster analysis shows the splitting of consumer preferences, highlighting the higher acceptance of traditional Bord�� wine and static pomace samples in all sensory attributes. Pre-drying process enhances the concentration of coloured compounds, to highlight the appearance acceptance of these samples. Research limitations/implications: Although this paper has limited the consumer acceptance of red table wines, the innovative treatments will be applied in Vitis vinifera red wines. Practical implications: The wide acceptance of static pomace and pre-drying wines has promoted further information about innovative winemaking that can be applied in Brazilian and worldwide wineries. Social implications: The innovative treatments can change sensorial features of wines and therefore influence the choice of consumers as well as enhancing the nutritional benefits of red wines. Originality/value: The pre-drying and static pomace winemaking are the novelty of this study and the wide acceptance of the sensory attributes concerning these treatments indicates the potential for application in wineries. �� Emerald Group Publishing Limited.

Biological therapy for the prevention and treatment of postoperative endoscopic recurrence in Crohn's disease: time for acceptance?

In most patients, postoperative endoscopic recurrence (PER) occurs 1 year after abdominal resection for Crohn���s disease (CD). Preventing PER is essential for disease control, as most patients develop further clinical and surgical recurrences. Conventional therapy with nitroimidazoles, aminosalicylates, and immunomodulators have limited efficacy for preventing PER. Initial trials with biological therapy (infliximab and adalimumab) showed promising results in preventing PER, and the efficacy of these drugs seems higher than that with conventional therapy. The aim of this review is to outline the results of studies that used infliximab or adalimumab for preventing and treating PER in CD patients. Data with both agents are available, and a few, small prospective trials have shown the efficacy of these drugs in patients with a high risk for recurrence. We believe that, in 2013, biological agents will be better accepted for the prevention PER in CD patients, in addition to the already existing data. Larger trials are still underway, and their results will certainly determine the role of these agents in PER, which develops after bowel resection for CD.

Information Acceptance and ICT Resistance: Promoting the Role of Information in Rural Community Development

Rural community development is a major issue for developing countries. Much attention has been given Information and Communication Technology (ICT) projects to connect rural communities with the global network. However, ICT resistance is a deterring factor in addressing the digital divide in developing countries. It is postulated that reversing the resistance to to ICT can be strategizedthrough "information acceptance." ICT can be accepted by rural communities by creating demand for information. The paper calls for the refocusing on the role of information in rural community development and ICT as a tool for change agent. Initiatives for rural community development must emphasize the importance of information in rural communities.

Early IL-10 production is essential for syngeneic graft acceptance

We performed a comparative study and evaluated cellular infiltrates and anti-inflammatory cytokine production at different time-points after syngeneic or allogeneic skin transplantation. We observed an early IL-10 production in syngeneic grafts compared with allografts. This observation prompted us to investigate the role of IL-10 in isograft acceptance. For this, we used IL-10 KO and WT mice to perform syngeneic transplantation, where IL-10 was absent in the graft or in the recipient. The majority of syngeneic grafts derived from IL-10 KO donors did not engraft or was only partially accepted, whereas IL-10 KO mice transplanted with skin from WT donors accepted the graft. We evaluated IL-10 producers in the transplanted skin and observed that epithelial cells were the major source. Taken together, our data show that production of IL-10 by donor cells, but not by the recipient, is determinant for graft acceptance and strongly suggest that production of this cytokine by keratinocytes immediately upon transplantation is necessary for isograft survival.

Science and Society: The Case of Acceptance of Newtonian Optics in the Eighteenth Century

The present paper presents a historical study on the acceptance of Newton's corpuscular theory of light in the early eighteenth century. Isaac Newton first published his famous book Opticks in 1704. After its publication, it became quite popular and was an almost mandatory presence in cultural life of Enlightenment societies. However, Newton's optics did not become popular only via his own words and hands, but also via public lectures and short books with scientific contents devoted to general public (including women) that emerged in the period as a sort of entertainment business. Lectures and writers stressed the inductivist approach to the study of nature and presented Newton's ideas about optics as they were consensual among natural philosophers in the period. The historical case study presented in this paper illustrates relevant aspects of nature of science, which can be explored by students of physics on undergraduate level or in physics teacher training programs.

It is a matter of taste: chemical signals mediate nuptial gift acceptance in a neotropical spider

Nuptial gift offering is a courtship trait found among several insect orders and some spider families. Recent studies indicate that this gift-giving behavior in spiders represents the male mating effort acting on female receptivity through a mechanism of foraging motivation. However, little attention has been given to the sensory channels that are influencing female acceptance. To understand the role of these sensory channels in female perception of a nuptial gift, we focused on the nuptial gift of the neotropical spider Paratrechalea ornata (Araneae, Trechaleidae). The nuptial gift of this species is composed of a prey item wrapped in silk, and previous works suggest that visual and/or chemical cues may be involved in inducing female grasping behavior. We isolated sensory channels using mimetic nuptial gifts (artificial items) or by manipulating real nuptial gifts. Isolated visual signals were not responsible for female acceptance, whereas chemical signals found within the nuptial gift silk layer induced female acceptance. Our findings clearly indicate that a chemical signal located in the silk of the nuptial gift is the main attractant channel, and we formulated 2 hypotheses to explain the mechanisms of action in the female sensory system. We also discuss the consequences of such signaling over female acceptance.

Acceptance Threshold Hypothesis is Supported by Chemical Similarity of Cuticular Hydrocarbons in a Stingless Bee, Melipona asilvai

The ability to discriminate nestmates from non-nestmates in insect societies is essential to protect colonies from conspecific invaders. The acceptance threshold hypothesis predicts that organisms whose recognition systems classify recipients without errors should optimize the balance between acceptance and rejection. In this process, cuticular hydrocarbons play an important role as cues of recognition in social insects. The aims of this study were to determine whether guards exhibit a restrictive level of rejection towards chemically distinct individuals, becoming more permissive during the encounters with either nestmate or non-nestmate individuals bearing chemically similar profiles. The study demonstrates that Melipona asilvai (Hymenoptera: Apidae: Meliponini) guards exhibit a flexible system of nestmate recognition according to the degree of chemical similarity between the incoming forager and its own cuticular hydrocarbons profile. Guards became less restrictive in their acceptance rates when they encounter non-nestmates with highly similar chemical profiles, which they probably mistake for nestmates, hence broadening their acceptance level.

Human leukocyte antigen-G 3 ' untranslated region polymorphisms are associated with better kidney allograft acceptance

Human leukocyte antigen-G (FILA-G) plays a well-recognized role in the modulation of the immune response, and HLA-G expression has been associated with increased graft survival and decreased rejection episodes. To investigate the role of the HLA-G 3' untranslated region (3'UTR) in renal transplantation, we evaluated several polymorphic sites (14-bp Del/Ins +3003T/C, +3010C/G, +3027C/A, +3035C/T, +3142G/C, and +3187A/G) in patients exhibiting or not exhibiting rejection episodes. A total of 104 patients (15 with acute and 48 with chronic rejection, and 41 with no rejection) and 142 healthy individuals were studied. HLA-G 3'UTR was typed by direct sequencing. The +3035C-C genotype was more frequent in patients exhibiting chronic rejection compared with healthy controls, and the +3035C-T genotype was less frequent in chronic rejection compared with patients without rejection (acute plus chronic) or compared with healthy controls. The +3187G-A genotype, in which the A allele is associated with increased mRNA degradation, showed increased frequency in the rejection group (acute plus chronic) when compared with healthy controls. The 14 base pair Deletion/Insertion genotype was marginally increased in patients with acute rejection. This is the first study to show associations among numerous polymorphic sites in the HLA-G 3'UTR in kidney allotransplantation, which may contribute to the understanding of HLA-G post-transcriptional mechanisms.

Technology Development and Consumer Acceptance of Innovation in Fruit Production

Precision Agriculture (PA) and the more specific branch of Precision Horticulture are two very promising sectors. They focus on the use of technologies in agriculture to optimize the use of inputs, so to reach a better efficiency, and minimize waste of resources. This important objective motivated many researchers and companies to search new technology solutions. Sometimes the effort proved to be a good seed, but sometimes an unfeasible idea. So that PA, from its birth more or less 25 years ago, is still a ���new��� management, interesting for the future, but an actual low adoption rate is still reported by experts and researchers. This work aims to give a contribution in finding the causes of this low adoption rate and proposing a methodological solution to this problem. The first step was to examine prior research about Precision Agriculture adoption, by ex ante and ex post approach. It was supposed as important to find connections between these two phases of a purchase experience. In fact, the ex ante studies dealt with potential consumer���s perceptions before a usage experience occurred, therefore before purchasing a technology, while the ex post studies described the drivers which made a farmer become an end-user of PA technology. Then, an example of consumer research is presented. This was an ex ante research focused on pre-prototype technology for fruit production. This kind of research could give precious information about consumer acceptance before reaching an advanced development phase of the technology, and so to have the possibility to change something with the least financial impact. The final step was to develop the pre-prototype technology that was the subject of the consumer acceptance research and test its technical characteristics.
