Abstract :

A new type of pH-responsive multi-blocked polyurethane for drug delivery applications was prepared and characterized by GPC, 1H-NMR and FT-IR. Then, polyurethane micelles was prepared by dialysis method, and the critical micelle concentration was 2.5×10-3 g/L as measured by fluorescence technique. TEM and DLS analysises showed that the size of spherical micelles increased from 89.2nm at physiological pH 7.4 to 320 nm at an acidic environment, i.e. pH 5.5, the pH value of intracellular microenvironment of cancer cells. Finally, a hydrophobic anti-cancer drug methotrexate (MTX) was used as a model drug to study the drug release profiles of the drug loaded micelles at neutral and acid environment. The results showed that the drug release is much faster at pH 5.5 than that at pH 7.4. Therefore, the synthesized polyurethanes are promising to be used as pH-responsive drug carriers.

Abstract :

Post occupancy evaluation (POE) is defined as the process of evaluating building systematically and comprehensively after user occupied. What makes this process differs significantly from other conventional surveys is that it uses the direct, unmediated experiences of building users as the basis for evaluating how a building works for its intended use. Focusing mainly on building users and their needs, provides them with the opportunity to participate in the evaluation process, and this makes them take more ownership in the building. This paper reviews approaches used in carrying out post occupancy evaluation process in educational buildings. It focuses on evaluating the environmental aspects as the core interest of users. It develops a framework for user-centered post occupancy evaluation that correlates a combined set of environmental assessment aspects, to evaluation methods and techniques classified as either qualitative or analytical. Finally, another dimension is added to this framework by ranking the evaluation methods and techniques regarding the degree of user involvement.

Abstract :

Revision operations after joint implantation, as well as complications occurring with trauma patients, whose implants are made of metal are becoming more and more frequent economic and medical problem. The most frequent reason for revision operations is aseptic loosening of joints.As early as the 1970`s, there appeared the descriptions of cases, which suggested side reactions, which followed metal implantations. In most cases it is methalosis and fistula. Sometimes they assume a form of: eczema, erythema, pruritus and others in the side of implantation, which point to allergic reaction.The article presents the analysis of clinical operation complications after the treatment of long bones by mean of ostheosynthesis with the use of metal implants and endoprothesoplastic of hip joints.

Abstract :

Background: The aim of this study was to analyze the most appropriate surgical strategy in the management of patients with major inflammatory complications of colonic diverticular disease.

Materials and Methods: Out of 539 patients affect­ed by complicated diverticular disease of the colon, 125 consecutive patients (23.2%) who underwent urgent or emergency surgical intervention for diverticular per­foration during a 13 year period (2000-2013),  were ret­rospectively analyzed. According to the changes in the surgical approach over the time, the series was divid­ed into two groups: 2000-2005 Group A (n=59), 2006-2013 Group B (n=66). The clinical diagnosis was con­firmed by operative and pathologic findings.

Results: Out of 109 patients, 28 underwent derivative procedure and 81 resection. There were no significant differences among the two groups of patients accord­ing to sex ratio and mean age. The overall percentage of patients in group B who underwent resective proce­dure (91%) was significantly greater in comparison with that in group A (53%). Colostomy and drainage was employed only during the first period (30%), (Group A vs Group B, p<0.05) and the proportion of patients who underwent primary resection and anas­tomosis was significantly higher during the second period (41%), (Group B vs Group A, p<0.05).

Conclusions: It must be stressed that resection of the diseased segment at initial operation appears manda­tory; one-stage procedure is indicated when infection is confined to the mesentery, while resection and anas­tomosis with covering colostomy (two-stage procedure) is preferable whenever peritoneal contamination has occurred. According to the literature Hartmann’s operation may be the proce­dure of choice in the patients presenting known impaired immunity or fecal contamination.

Abstract :

A novel redox-sensitvie cross-linked micelles based on disulfide-linked polymer were prepared and characterized as potential carrier for drug delivery. In this experiment N,N-bis(acrylate) cystamine (BAC) served as cross-linker, poly(g-benzyl-L-glutamate) (PBLG) and polyethylene glycol (PEG) methyl ether methacrylate acted as comonomers. The molecular structure and characteristics of the cross-linked micelle was confirmed by 1H NMR and FT-IR. The copolymer was able to self-assembled into micelles, and the micellar nanostructure was investigated by DLS and TEM. The cross-linked micelles was designed to degraded into individual linear short chains in the presence of glutathione (GSH) by the cleavage of the disulfide linkages from the cross-linker BAC. All the results showed that the designed cross-linked polymeric micelles may be a promising carrier for drug delivery in intracellular reducing environment.

Abstract :

Background: Depression correlates positively with alexithymia. Less is known about the relationship between hostility and depression and even less about hostility and alexithymia. The aim of this study is to examine the relationship between alexithymia, hostility and depression.

Methods:  The study was carried out with 308 subjects: 102 patients suffering from somatic illnesses, 98 depressive patients and 108 healthy people. The mean age of the group was 40.26 years (sd=11.63); 184 of them were women and 124 were men. The participants were assessed with the Beck Depression Index (BDI-21), the 20-item Toronto Alexithymia Scale (TAS-20), the Hostility and Direction of Hostility Scale (HDHQ). Data regarding sociodemographic characteristics were also collected. Linear regression was performed to evaluate the relationship between the scores of the participants in each scale.

Results: Alexithymia scores correlate positively with depression scores (α= 41.73 and Β= 0.88, p= .000). Hostility scores correlate positively with depression scores (α= 15.66 and Β= 0.39, p= .000). Finally, alexithymia scores correlate positively with hostility scores (α= 31.05 and Β= 1.05, p= .000).

Conclusions: The more depressive somebody is, the more alexithymic and hostile he is likely to be; finally, the more hostile someone is, the more alexithymic he is likely to be.

Title : Application of Supercritical Carbon Dioxide for the Preservation of Fresh-Like Carrot Juice

Authors : Gabriele Di Giacomo, Francesca Scimia, Luca Taglieri

Abstract :

Supercritical carbon dioxide has been suggested and is under development for non-thermal pasteurization of food and perishable beverages by virtue of its effectiveness in microflora and enzyme inactivation.  In comparison to competitive technologies, it is particularly attractive at industrial scale since the liquids can be continuously processed with recirculating carbon dioxide. One of the most attracting application is the preservation of increasingly interesting fresh-like juices of fruits and vegetables, particularly the low acidic ones like carrot juice, for which the shelf life can be enhanced of about one order of magnitude (from two or three days to about three weeks or more) while maintaining the main characteristics of the fresh squeezed equivalent. Most of this exciting result is directly related to the unique reversible acidification action of this technology. In this study it has been found that Pectin methylesterase and Peroxidase are actually the solely responsible for cloud stability disappearance and off-flavor, browning and other enzymatic-related undesirable changes occurring during the storage of fresh-like carrot juice, under refrigerated conditions. In fact, the level of Polyphenol oxidase activity is very low and the level of fat in this juice is also very low, thereby nullifying the potential negative action of those enzymes that may cause adverse effects by acting on fats.  In this contest, it has been found, using a semi-continuous laboratory apparatus, that a micro-bubbled stream of supercritical carbon dioxide at 313 K, 25 MPa and juice/CO2 ratio (w/w) equal to 0.33, significantly inactivated the labile isoform fraction of PME (above 70%) and of POD (almost completely) in about one hour. The values of the stable isoform dimensionless activity of the above mentioned enzymes and of the inactivation constant were calculating by fitting experimental data with a plain, semi-empirical equation obtaining the following results: 0.0894 and 0.00345 min-1 for PME, and 0.1072 and 0.04035 min-1 for POD.

Abstract :

In frequency response methods, we vary the frequency of the input signal over a certain range and study the resulting response. Although the frequency response of the control system presents a qualitative picture of the transient response, correlation between frequency and transient response is indirect, except for the case of second order system in designing a closed loop system. We adjust the frequency response characteristic of the open loop transfer function by using several design criteria in order to obtain acceptable transient response characteristics for the system.

Abstract :

Anomalous signals prior to large earthquakes might be detected based on superconducting gravimeters (SGs) and broadband seismometers (BSs) records. In this study, we selected 12 large earthquakes with their seismic magnitudes larger than 7.8, occurred between 2006 and 2010. Hilbert-Huang transform (HHT) technique, which is applicable for nonlinear and non-stationary processes, was applied to SG record and BS data sets sampled at one-second interval covering the time span 7 days prior to and 1 day after these earthquakes. Our study shows that anomalous signals are likely to occur in any one of the several days prior to large earthquakes. The results based on the SG record show that the anomalous signals with dominant frequency around 0.13 Hz occur 16 hours to 5 days prior to the large earthquake. Whereas records from 48 BS station suggest four obvious intrinsic frequency bands, namely around 0.06Hz, 0.33Hz, 0.43Hz and 0.46Hz, respectively. Concerning the BS records, the anomalous signals are characterized by total increase of the energy of signals and the anomalous peaks of the marginal spectra around 0.15-0.2 Hz and 0.33 Hz.

Abstract :

Introduction: Although 67Ga-citrate has been used in scintigraphic imaging for lymphoma, the long physical half-life of 67Ga and inferior resolution of SPECT scanner limited the wide-spread application of this agent. In contrast, the ideal physical half-life of 68Ga and superior resolution of PET scanner push us to test lymphoma imaging potential of 68Ga-citrate. Materials: Sodium citrate was added into newly eluted 68Ga and incubated at room temperature for 15min for 68Ga-citrate preparation. Three patients with abdominal lymphoma were retrospectively analyzed after 68Ga-citrate PET/CT imaging. Results: 68Ga-citrate was labeled with >99% yield and purity within 15 minutes. 68Ga-citrate PET/CT revealed rapid progression of bowel diffuse large B-cell lymphoma in one patient; 68Ga-citrate revealed more lesion than 18F-FDG in another diffuse large B-cell lymphoma patient; 68Ga-citrate imaging was negative in an enteropathy-associated T cell lymphoma patient. Conclusion: A simplified method to prepare 68Ga-citrate without nuclide pre-purification is available. 68Ga-citrate can be used for lymphoma imaging and further evaluation is warranted.

Abstract :

No reference salvage regimen has been established in elderly patients with refractory or relapsed acute myeloid leukemia (AML). In our study, six patients older than 60 diagnosed with refractory or relapsed AML received programmed infusions of granulocyte colony-stimulating factor (G-CSF)–mobilized HLA-mismatched donor peripheral-blood stem cells after the DCAG regimen of chemotherapy treatment. The complete remission (CR) rate was 33.33% after the first therapy cycle. The median recovery times of neutrophils and platelets were 12 days and 14.5 days, respectively. No acute graft-versus-host disease (GVHD) or chronic GVHD was observed in any of the patients. The median overall survival (OS) time was 6.2 months (range, 0.9-26.2), and one out of six patients (16.7%) achieved persistent CR. In Conclusion, DCAG regimenin in combination with microtransplantation was well tolerated and showed a promising clinic efficacy in elderly patients with refractory or relapsed AML.

Abstract :

Heat exchanger using nano fluid is a device in which the heat transfer takes place by using nano fluid. In this the working fluid is nano fluid. Nano fluid is made by the suspending nano particles in the fluid like water, ethylene glycol and oil, hydrocarbons, fluorocarbons etc. An analysis of forced convection heat transfer has been carried out in a semifluid tube heat exchanger equipped with spiral coiled inserts using CuO/water as a nano fluid and distills water as base fluid. Tests has been conducted for plain tube and for tube with inserts for the determination of heat transfer, friction factor and thermal performance factor in the Reynolds number range 4000 to 10000 and volume concentration from 0.01%, 0.015% and 0.02% of nano fluid at room temperature. The results achieved from the use of the CuO/water nano fluid and helical coiled inserts, are compared with plain tube with and without inserts. The experimental results reveal that at similar operating conditions, heat transfer, friction factor as well as thermal performance factor associated with the simultaneous application of CuO/water nano fluid and spiral coiled insert are higher than those associated with the individual techniques. Evidently, heat transfer rate increases with increasing CuO/water nano fluid volume concentration and decreasing pitch ratio. In addition, the copper oxide based nano fluid coupled with helical coiled insert in a copper tube in parallel arrangement offer higher heat transfer performances than plain tube. In this experimental study, the maximum thermal performance factor 1.23 is found with the use of CuO/water nano fluid at volume concentration of 0.02% in copper tube coupled with helical coiled inserts at pitch ratio (p/d=2) in parallel arrangement, for Reynolds number of 4713.93.
