Influence of CLA supplementation on the lipid quality of rabbit meat

Lately, animal science researchers are getting more and more interested in natural nutraceuticals in feeds because of their beneficial effect both to the animal and to the consumer. Conjugated Linoleic Acid (CLA) consists of a pool of geometrical and positional isomers, acknowledged as a potent anti-carcinogenic, anti-atherogenic, anti-obesity, anti-diabetes and immune stimulating factor (Parodi, 1999). Food products from ruminant animals,milk in particular, are naturally more or less rich in CLA, depending on feeding. CLA may be increased by dietary means. Aim of the present study was an attempt to upgrade the lipid quality of rabbit meat by supplementing the diet with CLA

New Directions in Understanding Atopic March Starting from Atopic Dermatitis

Recent evidence showed that the postulated linear progression of the atopic march, from atopic dermatitis to food and respiratory allergies, does not capture the heterogeneity of allergic phenotypes, which are influenced by complex interactions between environmental, genetic, and psychosocial factors. Indeed, multiple atopic trajectories are possible in addition to the classic atopic march. Nevertheless, atopic dermatitis is often the first manifestation of an atopic march. Improved understanding of atopic dermatitis pathogenesis is warranted as this could represent a turning point in the prevention of atopic march. In this review, we outline the recent findings on the pathogenetic mechanisms leading to atopic dermatitis that could be targeted by intervention strategies for the prevention of atopic march

Anlisis Technology Acceptance Model Pada Industri Perbankan

The first aim of this study was to determine the influence perception of the perceived benefits (PU) and perceived ease of use (PEU) of the attitude (ATU) in receiving information technology (ATI). This research is an explanatory research. Respondents are bank employees as much as 118 peoples. To test the effect of each variable used structural equation modeling analysis techniques (SEM). The results showed a variable perception ease of use (PEU) positive and significant impact on the attitude of using IT (ATU). Variable perception perceived benefits (PU) is positive but not significant effect on attitudes using IT (ATU). Variable perception easy to use (PEU) positive and significant impact on the perceived benefits perception variables (PU). Variable attitude of using IT (ATU) positive and significant impact on the acceptance of IT (ATI). There are research findings that do not support the results of previous studies, namely, perception perceived benefits (PU) but not significant positive effect on the attitude of using IT (ATU). This shows the attitude of the management agreed that the use of information technology is an important banking and its presence is felt very beneficial to the organization and operational staff, but not the key element in determining the attitude to use IT. The management should be able to realize the quality of skilled workers and professional service. The banking industry can standardize that can be used as a reference for the development of IT. IT use also should be able to grow the level of trust and a culture conducive to the customer as a party that directly or indirectly affect the use of IT

Human mesenchymal stromal cells inhibit tumor growth in orthotopic glioblastoma xenografts

Background: Mesenchymal stem/stromal cells (MSCs) represent an attractive tool for cell-based cancer therapy mainly because of their ability to migrate to tumors and to release bioactive molecules. However, the impact of MSCs on tumor growth has not been fully established. We previously demonstrated that murine MSCs show a strong tropism towards glioblastoma (GBM) brain xenografts and that these cells are able to uptake and release the chemotherapeutic drug paclitaxel (PTX), maintaining their tropism towards the tumor. Here, we address the therapy-relevant issue of using MSCs from human donors (hMSCs) for local or systemic administration in orthotopic GBM models, including xenografts of patient-derived glioma stem cells (GSCs). Methods: U87MG or GSC1 cells expressing the green fluorescent protein (GFP) were grafted onto the striatum of immunosuppressed rats. Adipose hMSCs (Ad-hMSCs), fluorescently labeled with the mCherry protein, were inoculated adjacent to or into the tumor. In rats bearing U87MG xenografts, systemic injections of Ad-hMSCs or bone marrow (BM)-hMSCs were done via the femoral vein or carotid artery. In each experiment, either PTX-loaded or unloaded hMSCs were used. To characterize the effects of hMSCs on tumor growth, we analyzed survival, tumor volume, tumor cell proliferation, and microvascular density. Results: Overall, the AD-hMSCs showed remarkable tropism towards the tumor. Intracerebral injection of Ad-hMSCs significantly improved the survival of rats with U87MG xenografts. This effect was associated with a reduction in tumor growth, tumor cell proliferation, and microvascular density. In GSC1 xenografts, intratumoral injection of Ad-hMSCs depleted the tumor cell population and induced migration of resident microglial cells. Overall, PTX loading did not significantly enhance the antitumor potential of hMSCs. Systemically injected Ad- and BM-hMSCs homed to tumor xenografts. The efficiency of hMSC homing ranged between 0.02 and 0.5% of the injected cells, depending both on the route of cell injection and on the source from which the hMSCs were derived. Importantly, systemically injected PTX-loaded hMSCs that homed to the xenograft induced cytotoxic damage to the surrounding tumor cells. Conclusions: hMSCs have a therapeutic potential in GBM brain xenografts which is also expressed against the GSC population. In this context, PTX loading of hMSCs seems to play a minor role

Mast Cell Activation Disorders

Background and Objectives: Mast cell disorders comprise a wide spectrum of syndromes caused by mast cells’ degranulation with acute or chronic clinical manifestations. Materials and Methods: In this review article we reviewed the latest findings in scientific papers about mast cell disorders with a particular focus on mast cell activation syndrome and mastocytosis in pediatric age. Results: Patients with mast cell activation syndrome have a normal number of mast cells that are hyperreactive upon stimulation of various triggers. We tried to emphasize the diagnostic criteria, differential diagnosis, and therapeutic strategies. Another primary mast cell disorder is mastocytosis, a condition with a long-known disease, in which patients have an increased number of mast cells that accumulate in different regions of the body with different clinical evolution in pediatric age. Conclusions: Mast cell activation syndrome overlaps with different clinical entities. No consensus was found on biomarkers and no clearly resolutive treatment is available. Therefore, a more detailed knowledge of this syndrome is of fundamental importance for a correct diagnosis and effective therapy

Influence of Atopic Dermatitis on Cow’s Milk Allergy in Children

Background and Objectives: Cow’s milk protein allergy (CMA) is the most common allergy in children. The natural history of CMA is generally favorable and the majority of children reach tolerance during childhood, even if studies show variable results. Atopic dermatitis (AD) is a complex disease from an immunological point of view. It is characterized by an impaired skin barrier function and is often the first clinical manifestation of the so-called “atopic march”. The aim of our study is to evaluate, in a cohort of children with CMA, if the presence of AD in the first months of life can influence the atopic status of patients, the tolerance acquisition to cow’s milk, the level of specific IgE (sIgE), and the sensitization towards food and/or inhalant allergens. Materials and Methods: We enrolled 100 children with a diagnosis of CMA referred to our Pediatric Allergology Unit, aged 1–24 months at the time of the first visit. Results: 71 children had AD and 29 did not. The mean follow-up was 5.28 years. The CMA manifestations were mainly cutaneous, especially in children with AD (91.6% vs. 51.7%; P < 0.001). Patients with AD showed higher rates of polysensitization to foods and higher levels of both total IgE and sIgE for milk, casein, wheat, peanuts, and cat dander at different ages when compared to patients without AD. We analyzed the presence of IgE sensitization for the main foods and inhalants at various ages in the two groups of patients: a statistically significant difference emerged in the two groups of patients for milk, yolk and egg white, hazelnut, peanuts, soybean, grass pollen and cat dander. Meanwhile, we did not find significant differences in terms of tolerance acquisition toward cow’s milk, which was nonetheless reached around 5 years of age in 61% of patients. The level of cow’s milk sIgE at the age of 5 years was significantly higher in the group of patients who did not acquire tolerance (38.38 vs. 5.22 kU/L; P < 0.0001). Conclusions: An early barrier deficiency appears to promote the development of allergic sensitization, but does not seem to influence the acquisition of tolerance
