Adenovirus type 2 (Ad2) binds the coxsackie B virus Ad receptor and is endocytosed upon activation of the αv integrin coreceptors. Here, we demonstrate that expression of dominant negative clathrin hub, eps15, or K44A-dynamin (dyn) inhibited Ad2 uptake into epithelial cells, indicating clathrin-dependent viral endocytosis. Surprisingly, Ad strongly stimulated the endocytic uptake of fluid phase tracers, coincident with virus internalization but without affecting receptor-mediated transferrin uptake. A large amount of the stimulated endocytic activity was macropinocytosis. Macropinocytosis depended on αv integrins, PKC, F-actin, and the amiloride-sensitive Na+/H+ exchanger, which are all required for Ad escape from endosomes and infection. Macropinocytosis stimulation was not a consequence of viral escape, since it occurred in K44A-dyn–expressing cells. Surprisingly, 30–50% of the endosomal contents were released into the cytosol of control and also K44A-dyn–expressing cells, and the number of fluid phase–positive endosomes dropped below the levels of noninfected cells, indicating macropinosomal lysis. The release of macropinosomal contents was Ad dose dependent, but the presence of Ad particles on macropinosomal membranes was not sufficient for contents release. We conclude that Ad signaling from the cell surface controls the induction of macropinosome formation and leakage, and this correlates with viral exit to the cytosol and infection.

Research on the parameters of full blood count and differential white blood count is included in the program of all medical laboratories of primary, secondary and tertiary health care levels. Today, all haematological tests are exclusively performed on the haematology analyzers. Automation of haematology laboratories is a result of the huge requires for haematological test performing, timely issuing of the haematological findings, and possibility of the usage of modern techniques.This work is an evaluation of laser haematology analyzer Cell-Dyn 3700 SL. It investigates the reliability of test results throughout the following parameters: precision, accuracy, sensitivity and specificity of determination methods. It also explores the influence of sample transferring and correlation with haematology analyzer MAXM Retti. Haematology parameters that have been investigated are: white blood cell (WBC), neutrophils (NEU), lymphocytes (LXM), monocytes (MONO), eosinophils (EOS), basophils (BASO), red blood cells (RBC), haemoglobin (HGB), haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCHC) red cell distribution width (RDW), platelet (PLT), mean platelet volume (MPV), plateletocrit (PCT), and platelet distribution width (PDW).The results confirms that precision of analyzer fulfils the reproducibility of testing parameters: WBC, RBC, HGB, MCV, MCH, MCHC, and PLT. Correlation coefficient values (r) gained throughout the statistical analysis, that is linear regression results obtained throughout the comparison of two analyzers are adequate except for MCHC (r = 0.64), what is in accordance with literature data.Accuracy is tested by haematology analyzer method and microscopic differentiating method. Correlation coefficient results for granulocytes, lymphocytes and monocytes point the accuracy of methods. Sensitivity and specificity parameters fulfil the analytical criteria.It is confirmed that haematology analyzer Cell-Dyn 3700 SL is reliable for the determination of full blood count in everyday work. Analyzer and its program for differential white blood count can be used for the research and separation of normal and pathological blood counts with addition of microscopic methods confirming distribution or morphologic changes of leukocytes.

The objective of this study was to evaluate the influence of time of sample storage, method of analysis, and storage temperature on stability of HCT, HGB, and RBC in avian blood samples. Blood samples from mute swans were stored at 24°C or 4°C. Analyses of HCT, HGB, and RBC were carried out after 5 and 25 hours after collection of blood using both traditional and Cell-Dyn 3700 analyzer methods. Storage temperature had no significant influence on HCT, HGB, and RBC values of mute swan blood. However hematological parameters obtained by the traditional method were significantly lower than the results from the analyzer. Time of storage had a significant influence on values obtained traditionally for HCT, HGB, and RBC, but did not affect results that were obtained by the multi-parameter automated method. These results indicate that the mute swan blood can be stored at both room and refrigerator temperature. However, the analysis should be performed as soon as possible, especially in the case of traditional methods. Reference intervals for this species should always include information about the method used for hemogram determination and time elapsed since the blood collection.

AbstractBackgroundBlood counters are primarily used to measure peripheral blood cells including platelets (PLTs). In routine quality control of platelet concentrates (PCs), counters are also used to analyze very high PLT counts. To meet the requirements of national and European guidelines for quality assurance, the accuracy of counting very high PLT counts has to be validated. The aim of the present study was to validate four blood counters (one of which has two detection methods) focusing on the PLT count.MethodsThe comparison was performed with PCs using the blood counter devices CELL-DYN Ruby (optical count) and CELL-DYN Emerald (impedance count), Sysmex K-4500 (impedance count), Sysmex XN-550 (impedance count) and Sysmex XN-550 (optical count). For precision performances, samples were measured serially 5 times and the coefficients of variation were calculated and compared with manufacturers’ requirements. Additionally, 50 peripheral blood samples were analyzed and standard hemogram parameters (red blood cells [RBC], white blood cells [WBC], hemoglobin [HGB], hematocrit [HCT], PLTs) were compared.ResultsThe comparison showed significant differences between the studied blood counter devices in measuring high PLT counts. The CELL-DYN-Emerald, the Sysmex K-4500 and Sysmex XN-500 with the optical counting method measured significantly higher PLT counts compared to the CELL-DYN-Ruby and the Sysmex XN-500 with the impedance counting technology (p<0.0001) independent of their principle of measurement. The manufacturers provide comparable coefficients of variation. We achieved similar results for all counters. All results of the peripheral blood count parameters were comparable.ConclusionsOur study showed the importance of blood counter validations focusing on PCs with high PLT counts before routine use. Not only the generally fundamental method, but also the manufacturers’ peculiarities seem to play an important role.

Complete blood count (CBC) is one of the laboratory tests most often influenced by doctors. The use of a hematology analyzer offers a wider range of probe parameters. The pre-analytic stage accounts for 70% of errors, one of which is the delay of the examination. Changes in report results were reported due to changes in blood cell morphology due to EDTA additives and room temperature. The aim of this research is the disturbance of stability of the results of examination of various CBC parameters in blood samples that are left at room temperature for 24 hours using a hematology analyzer. This experimental laboratory research was conducted at the Pramita Jemur Andayani Clinical Laboratory. Blood samples were obtained from volunteers, stored at room temperature and subjected to immediate examination (control) and after a delay of 6, 12 and 24 hours (treatment). A total of 30 respondents, consisting of 8 men and 22 women. The mean age of the respondents was 22 ± 1 year. There was no difference in the results of the examination (p-value > 0.05) in the RBC, Hct MCV, MCHC, PLT and PDW. The results of the examination (p-value < 0.05) were found on Hgb, MCH, RDW, WBC, NEU, IG, MONO, EO, BASO, LYM, PLT and PDW. Delayed CBC examinations using the CELL-DYN Ruby hematology analyzer directly gave different results on several parameters ranging from 6 hours delay of examination.

The article presents the design of a drum furnace, providing for the provision of differentiated heat flows through the use of an internal perforated pipe. The design of the presented horizontal drum dryer with a perforated tube having openings is designed to eliminate such technological risk factors as the ignition of the oil component of the processed material, and the metal dispersed material itself having pyrophoric properties. As a result of the numerical simulation using the LS–DYNA program, the temperature and heat fluxes in the quasi-boiling zone of the drained oil-containing dispersed material were determined. The calculations made it possible to establish the dependence of the temperature in the quasi-boiling zone on the number of holes of the perforated pipe. Analysis of the obtained graphs allows us to conclude that the gradient of temperature (heat) flows in fixed sections of the furnace of the quasi-boiling zone.

This master’s thesis deals with the design of equipment for testing differentials. The aim of the thesis is therefore the design of a special device that will be able to measure the steady and transient characteristics of differentials. Master’s thesis is divided into four chapters. The first chapter points out the disadvantages of fully open and closed differentials, the second deals with a basic overview of the structures and design of self-locking differentials. The third chapter deals with research of existing devices that test and measure the characteristics of differentials. The fourth chapter then discusses the possible drives of the tested unit. The fifth chapter focuses on the actual construction design of the test equipment. The subsequent sixth chapter then solves the strength calculations of the chosen structural elements of this device.
