Aim. Identifi cation of possible histological differences of the Quilty effect in acute rejection and its absence as well as studying the proliferation of blood and lymph vessels in the area of Quilty damage.Materials and methods. 883 endomyocardial biopsy materials from 352 patients were studied. Histological sections were stained with hematoxylin and eosin, Masson method; the endothelium of lymphatic vessels was stained with immunoperoxidase method using a marker D2-40.Results. The Quilty effect was observed both in acute rejection and inits absence. In the majority of cases the Quilty effect was of type «A» and it was combined with acute rejection. The Quilty effect of type «B» has been mostly in the G2R. Acute rejection is characterized by diffuse form of endocardium lymphoid infi ltration. Follicular form resembles lymphoid organ tissue. Different types and forms of the Quilty effect may be combined in the same biopsy. Proliferation of blood vessels presents in the area of the Quilty effect. Lymphatic vessels are missing in endocardium and in the area of the Quilty effect. They could be found only in the myocardium of endomiocardial biopsy.Conclusion. Diffuse lymphoid infi ltration of the endocardium is a characteristic feature of acute rejection of the transplanted heart. Follicular form of the Quilty effect is similar to lymphoid tissue whose role requires further study using immunohistochemical methods.

AbstractLense-Thirring QPO model is a promising model to explain QPO phenomena (Ingram et al. (2009)). In this model the QPO results from Lense-Thirring precession of a optical translucent inner hot flow in a truncated disc geometry. Now we check this model with different types QPO (see (Belloni et al. (2011)) for a recent review) of black hole transient (BHT) GX 339-4 2010 outburst and suggest type C QPOs are mainly coincident with this model prediction while type B QPOs are not.

This study was conducted to determine the contamination of E. coli and Salmonella for different types of foods in Chittagong city area. In case of laboratory examination, almost half (49.58%) of the samples were contaminated where 28.75% positive for E. coli. and 20.83% for Salmonella. The positive cases for type A sample was 20 out of 96 constituting 20.83% whereas the positive cases for type B sample was 49 out of 144 constituting 34.03% for E. coli. The positive cases of type A sample was 15 out of 96 making up 15.63% and for type B sample was 35 out of 144 making up 24.31% for Salmonella.A chi-square (?2) test was used to examine the equality of observed proportions for E. coli and Salmonella of each item of both types of food where significant difference among the observed proportion for E. coli (p-value<0.01) and Salmonella (p-value=0.032) for different items of A type and for E. coli (p-value<0.01) for different items of B type were observed and an odds ratio (OR) was measured for association between exposure and outcome where the probability of contaminated by E. coli of type B food is higher than contaminated of type A food (OR= 1.96 and CI:1.07-3.58). The probability of contaminated by Salmonella of type B food was higher than type A food (OR= 1.73 and CI: 0.89-3.39).The comparatively high bacteria in type B samples indicated contamination from water, practice of inadequate hygienic measures, mishandling, improper storage, inadequate cooking and above all unhygienic condition of the retail shops.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22034 J.

Early Cervical Cancer

The determination of factors associated with progression of cervical cancer is important, both for a recurrence risk assessment and for determining optimal treatment tactics. Previously, we showed the prognostic value of different types of tumor microvessels (MVs) in gastric and breast cancer. The object of this research was to study the morphology and clinical significance of different tumor microvessels in early cervical cancer. A total of 65 archived paraffin blocks of patients with I-IIA stages of squamous cervical cancer were investigated. Samples were stained with Mayer hematoxylin and immunohistochemically using antibodies to CD34, podoplanin, HIF-1a, and Snail. The eight types of tumor MVs differed in morphology were identified. It was established that only the dilated capillaries (DСs) with weak expression of CD34, the contact type DCs, the capillaries in tumor solid component, and the lymphatic vessels in the lymphoid and polymorphic cell infiltrates of tumor stroma are associated with clinical and pathological characteristics of early cervical cancer. Preliminary results also suggest that a combination of fragmentation in tumor solid component and the contact type DCs may predict a recurrence of early cervical cancer. Given the small number of cervical cancer recurrences, the predictive significance of the described markers requires a more thorough examination.

Bed Thickness

Archean pyroclastic rocks at Reneault and D'Alembert in the Noranda region are composed of crystals and lithic, vitric and pumiceous fragments. The pyroclastic rocks contain two types of beds, whose primary structure sequences and other characteristics show that the deposits accumulated from different types of density flows. The first bed-type (A) is characterized by greater bed-thickness, reverse grading and the coarsest fragments in the deposit. Closest to source, the primary structure sequence in Type A beds is indicative of deposition from debris flows, but in more distal sections it suggests deposition from turbulent suspensions. The second bed-type (B) is characterized by a smaller fragment size, thinner beds, normal grading and the presence of parallel and (or) oblique stratifications. The primary structure sequence in Type B beds is similar to that observed in turbidites, which suggests deposition from turbulent suspensions of low density.Lateral and vertical variations of grain size, bed thickness and structure sequences indicate that the vent was south of Reneault and that the volcanic activity increased with time. Pillowed flows both underlie and overlie the pyroclastic units which suggests accumulation under water, but there is evidence that some eruptions were subaerial.

The Impact

In this contribution the influence of different types of recombination-active defects on the integral electrical properties of multicrystalline Si solar cells is investigated. Based on a previous classification scheme related to the luminescence behavior of crystal defects, Type-A and Type-B defects are locally distinguished. It is shown that Type-A defects, correlated to iron contaminations, are dominating the efficiency by more than 20% relative through their impact on the short circuit current ISC and open circuit voltage VOC in standard Si material (only limited by recombination active crystal defects). Contrarily, Type-B defects show low influence on the efficiency of 3% relative. The impact of the detrimental Type-A defects on the electrical parameters is studied as a function of the block height. A clear correlation between the area fraction of Type-A defects and both the global Isc and the prebreakdown behavior (reverse current) in voltage regime-2 (−11 V) is observed. An outlier having an increased full-area recombination activity is traced back to dense inter- and intragrain nucleation of Fe precipitates. Based on these results it is concluded that Type-A defects are the most detrimental defects in Si solar cells (having efficiencies > 15%) and have to be prevented by optimized Si material quality and solar cell process conditions.

The paper analyses the stylistic and compositional characteristics of borders in a manuscript consisting of the first two romances of the Lancelot-Graal Cycle (Estoire del saint Graal, Merlin with Suite Vulgate) and two non-Arthurian texts (Le Roman de sept sages, Pénitence Adam). Two different types of borders are present, and in the article they are named type A and type B. They were employed with regard to the position of the miniature in the page: where the miniature appears in the left column, type A was used, and where it appears in the right column, type B was employed. The borders of type A embrace the text from three sides: the vertical border runs along the left column, and both horizontal ones spread over the space of both textual columns. In the case of type B, the vertical border runs along the right side of the right column, that is between the two columns, but closer to the right one; on the top and bottom, horizontal borders spring from the centre to both sides (over both columns). Certain compositions make it possible to assume that the main illuminator or the planner of the overall appearance of the manuscript was actively present also as far as the borders are concerned. Other details – e.g. gold background when two figures form contact with their bodies, and the lack of such a background, when they do not touch or touch only with their weapons – may testify to a personal intervention of the practising artist, and this may be characterized as a stylistic trait revealing his mente propria.

Based on the fact that bauxite clinker has minor thermal conductivity and better skid resistance and wear-resisting property, it can be used in HFST (high friction surface treatment) or the abrasion layer of asphalt mixture to replace or partly replace the existing aggregate. Bauxite clinker is classified into mainly six types according to different chemical composition contents. The selection of bauxite clinker as aggregate is not only for the economic value, but also for improving the adhesion between aggregate and asphalt, which has a certain blindness This study evaluated the characteristics of different types of bauxite clinker. The adhesion of different types of bauxite clinker with asphalt was evaluated by means of agitating hydrostatic adsorption method and surface free energy theory. The effect of characteristic parameters of bauxite clinker on adhesion was evaluated by grey correlation entropy analysis. The results show that Type B and D bauxite clinker aggregates have the best adhesion to asphalt. The outcome of grey entropy correlation analysis shows that the parameters which characterize the structural indexes of bauxite clinker, such as porosity, water absorption and apparent density, have the greatest effect on the adhesion. The results of study can provide some reference for the selection of bauxite clinker, which is used in different types of highway construction, and a theoretical reference for the applicability research of bauxite clinker in asphalt mixture and the improvement of skid resistance and durability of pavement.

Abstract The early innate response after Mycobacterium bovis bacille Calmette-Guérin (BCG) vaccination is poorly characterized but probably decisive for subsequent protective immunity against tuberculosis. Therefore, we vaccinated mice with fluorescent BCG strains in the ear dorsum, as a surrogate of intradermal vaccination in humans. During the first 3 days, we tracked BCG host cells migrating out of the dermis to the auricular draining lymph nodes (ADLNs). Resident skin dendritic cells (DCs) or macrophages did not play a predominant role in early BCG capture and transport to ADLNs. The main BCG host cells rapidly recruited both in the dermis and ADLNs were neutrophils. Fluorescent green or red BCG strains injected into nonoverlapping sites were essentially sheltered by distinct neutrophils in the ADLN capsule, indicating that neutrophils had captured bacilli in peripheral tissue and transported them to the lymphoid organ. Strikingly, we observed BCG-infected neutrophils in the lumen of lymphatic vessels by confocal microscopy on ear dermis. Fluorescence-labeled neutrophils injected into the ears accumulated exclusively into the ipsilateral ADLN capsule after BCG vaccination. Thus, we provide in vivo evidence that neutrophils, like DCs or inflammatory monocytes, migrate via afferent lymphatics to lymphoid tissue and can shuttle live microorganisms.
