Effectiveness of different instant hand sanitizers against normal flora and some selected pathogenic bacteria
Authors: Ahmed Tasnia
Published: August 2019

To maintain hygienic life it is important to follow the rules of sanitation. Hand sanitation is one of the most necessary parts of keeping personal hygiene. As hands are used directly for person to person contact, contact with animals, food preparation and so on, they can transmit microorganisms to and from all of these sources coming in contact. So if proper hand sanitation is maintained, the transfer of microorganisms will be decreased which can ultimately reduce the transmission of some pathogenic microorganisms to a susceptible host from own self directly or from the animals after handling them. Susceptible people getting harmful pathogenic bacteria can get sick if they find their appropriate routes of entry into them. During food preparation and taking meals, microorganisms can get entrance into the body from hands as well as microbes contaminating foods from the hands can proliferate in the foods causing spoilage and also release toxins causing food borne infection and food borne intoxication respectively. To reduce such risks people need to wash hands on routine basis especially on food processing zone it should be washed with water and soap which results in greater cleaning. People now use instant hand sanitizer after washing hands with water giving an extra protection. Sanitizers works best on hands with no visible sign of dirt. In the current study, five alcohol based hand sanitizers were selected to determine the ability of these sanitizers to decrease the loads of microorganisms from the hands of the five selected volunteers. During the study, it has been found that alcohol based instant hand sanitizer do decrease the loads of microbial flora from the hands but not in satisfactory level. Even they possessed very low effectivity against some pathogenic bacteria. These products can be used only where water is not available to decrease the loads of microbes from the hands.

The increasing trend of population and industrialization for economic growth has adversely been affecting fresh water resources that eventually leading to scarcity of available drinking water. Hence, controlling water pollution along with focusing on alternative water sources are important for ensuring access to safe drinking water. This study aimed to determine the biological water quality parameters of rainfall water in the water-scarce areas of Bangladesh. About sixty rainwater samples collected from seven different districts were collected for microbial analysis in particular Total Coliform (TC) and Fecal Coliform (FC) by using membrane filtration and direct counting method. The result found that 70 % of samples were free from total coliform, whereas only 5 % samples showed above 100 colonies. On the other hand, 83% samples were free from fecal coliform, whereas only 2% samples were within the range of 11-100 colonies. This study has also revealed that most of the samples collected from Rangamati and Khulna district were free from total coliform and fecal coliform. This study may also encourage people living in these water scarce areas to come forward for rainwater harvesting system as a prospective tool for achieving sustainable goal in drinking sector of Bangladesh.

The type of research used is research and development (R & D) with a 4D model. The subjects in this study were experts as validators, fifth grade students for trials and homeroom teachers in elementary schools. Data collection is done by giving a questionnaire to the validator. In this study the researchers concluded that the product of the developed linguistic intelligence assessment instrument was declared feasible to be used based on the results of validation of 86% with very feasible categories. The obstacle in developing the product of this instrument of linguistic intelligence assessment is the lack of knowledge of the school about the importance of linguistic intelligence for students in elementary schools.
Bendito tú eres entre todos los bandidos: el culto transfronterizo a Jesús Malverde (siglos XIX-XXI)
Authors: Rocha Carolina da Cunha
Published: August 2019

The purpose of this article is to analyze the religious aspect of the drug trafficking culture, in particular, the devotion to the popular saint Jesus Malverde in Mexico between the 19th and 21st centuries. The guiding hypothesis is that the worship of this saint has been resignified since the 1970s as a response to a stronger repressive apparatus against drugs due to the increase in drug use in the United States. The Malverdian cult was adopted by the drug trafficking culture in the most ostensive way, and it has crossed geographic and cultural borders.
Sedimantasyon & CRP - Geçmişten Geleceğe

İnflamasyon dokulara zarar veren herhangi
bir olaya karşı hasarı olabildiğince sınırlı tutmak ve nedeni ortadan kaldırmak
üzerine kurulu bir düzendir. Bu süreçte baş tehditleri içeriden metabolik,
romatizmal ve malign hastalıklar dışarıdan ise travma ve infeksiyon etkenleri
oluşturmaktadır. Pratik hekimlik hayatında inflamasyonu kantitatif olarak
değerlendirmek adına sıklıkla sedimantasyon ve C-reaktif protein (CRP) testleri kullanılmaktadır.
Sedimantasyon için normal değerin 50 yaş altı erkeklerde 15, kadınlarda 20
mm/saat; 50 yaş üzerinde ise erkeklerde 20 ve kadınlarda 30 mm/saat altında
olması beklenir. Sonucu çok çeşitli fizyolojik ya da prosedürel durumlar
etkilemektedir. İnflamatuar prosesin başlangıcında false negatif ya da sonunda
false pozitif sonuçlarla da karşılaşılabilmektedir. Sedimantasyon değeri
spesifik ve diagnostik olmamakla birlikte prognostik olabilmektedir. Ayrıca
hastalık varlığı, ciddiyeti ve aktivitesi hakkında fikir sunarak tekrarlanan
ölçümleriyle hastalık takiplerinde de yardımcı olabilmektedir. Yarılanma
ömrünün 4-6 gün kadar sürmesi nedeniyle takibinin genellikle haftalık sürelerle
yapılmasının uygun olacağı belirtilir. Bir çeşit akut faz proteini olan
C-reaktif proteinin sağlıklı bireylerdeki değeri ise ortalama 0,8 mg/L olup
toplumun çoğunluğunda 3 mg/L’nin altında seyretmektedir. Aterosklerozda intima tabakasında birikerek tüm
aşamalarda aktif rol oynadığının anlaşılmasıyla high sensitive C reaktif
protein (Hs-CRP) şeklindeki daha
düşük değerlerinin hassas bir şekilde ölçümü de devreye girmiştir. Burada 1,0 mg/L’den daha az değer kardiyovasküler olay açısından düşük riski, 3,0
mg/L üzerindeki sonuç yüksek riski ve aradaki değerler ise ortalama riski ifade
etmektedir. İkiye katlanma süresinin 8 saat sürmesi nedeniyle CRP yarı ömrünün 19 saat kadar olduğu belirtilmektedir.
Konsantrasyonları ile hastalığın ciddiyeti ve iki gün aralarla yapılan tedaviye
cevap kontrolleri arasında mükemmel korelasyon söz konusudur. Gerçek
inflamatuvar durumlarda her iki testin de birbirine paralel gitmesi beklenmekle
birlikte izole yüksekliklerde izlenebilmektedir. Bu makalede tarihsel

Published: August 2019

The present study was conducted to investigate the responsiveness expressions of ggTas2Rs against denatonium benzoate (DB) and genistein (GEN) in several organs of the Chinese Fast Yellow Chicken. A total of 300 one-day-old chicks that weighed an average of 32 g were randomly allocated into five groups with five replicates for 56 consecutive days. The dietary treatments consisted of basal diet, denatonium benzoate (5 mg/kg, 20 mg/kg, and 100 mg/kg), and genistein 25 mg/kg. The results of qRT-PCR indicated significantly (p < 0.05) high-level expressions in the heart, spleen, and lungs in the starter and grower stages except for in bursa Fabricius. The responsiveness expressions of ggTas2Rs against DB 100 mg/kg and GEN 25 mg/kg were highly dose-dependent in the heart, spleen, lungs, and kidneys in the starter and grower stages, but dose-independent in the bursa Fabricius in the finisher stage. The ggTas2Rs were highly expressed in lungs and the spleen, but lower in the bursa Fabricius among the organs. However, the organ growth performance significantly (p < 0.05) increased in the groups administered DB 5 mg/kg and GEN 25 mg/kg; meanwhile, the DB 20 mg/kg and DB 100 mg/kg treatments significantly reduced the growth of all the organs, respectively. These findings indicate that responsiveness expressions are dose-dependent, and bitterness sensitivity consequently decreases in aged chickens. Therefore, these findings may improve the production of new feedstuffs for chickens according to their growing stages.
Diagnosis of Feline Food Sensitivity and Intolerance Using Saliva: 1000 Cases
Authors: Dodds W. Jean
Published: August 2019

This prospective study assessed the efficacy of a novel saliva-based immunoassay of IgA- and IgM-antibodies in predicting feline food sensitivities and intolerances. Clinical samples were obtained from 1000 cats proven or suspected to have food intolerances. Most were of domestic shorthair breed type, over 10 years of age, and weighed around 5 kg; they were equally distributed between spayed females and neutered males. Saliva was collected after at least an 8-h fast with a dental cotton rope, placed in a double-sleeved saliva collection tube, and sent to the laboratory. Salivary antibodies elicited by 24 common foods were measured with goat anti-canine IgA and IgM. Low reacting foods were lamb, cow milk, pork, turkey, wheat (lowest) and white-colored fish, whereas high reacting foods were millet, white potato, rice (highest) and salmon. Thus, the novel salivary-based food sensitivity and intolerance test, described previously for canines, also provided a reliable and clinically predictive alternative to food elimination trials, serum-based food allergy testing, and skin patch testing in cats. Manufacturers of commercial cat foods and treats, as well as those making homemade diets and treats for cats, should consider avoiding the more highly reactive foods as determined by the present study.

Published: August 2019

A low testosterone level contributes to the development of oxidative damages; however, the cardiovascular effects of exogenous hormone therapy are not well elucidated. The aim of our work is to study the association of the testosterone level, antioxidant/oxidant system, and anti-inflammatory status related to the heme oxygenase (HO) system. To determine the effects of testosterone, 10-week-old, and 24-month-old sham-operated and castrated male Wistar rats were used. One part of the castrated animals was daily treated with 2.5 mg/kg cyproterone acetate, while the hormone replacement therapy was performed via an i.m. injection of a dose of 8.0 mg testosterone undecanoate/kg/once a week. The plasma testosterone level, the activity of HO and myeloperoxidase (MPO) enzymes; the concentrations of the HO-1, tumor necrosis alpha (TNF-α), and cyclic guanosine monophosphate (cGMP), as well as the total level of glutathione (GSH + GSSG) were determined from the cardiac left ventricle. In accordance with the testosterone values, the aging process and castration resulted in a decrease in antioxidant HO activity, HO-1 and cGMP concentrations and in the level of GSH + GSSG, whereas the inflammatory TNF-α and MPO activity significantly increased. Testosterone therapy was able to restore the physiological values. Our results clearly show that testosterone replacement therapy increases the antioxidant status and mitigates the inflammatory parameters via the modulation of the HO system.
Anticancer Activity of Essential Oils and Other Extracts from Aromatic Plants Grown in Greece
Authors: Fitsiou Eleni , Pappa Aglaia
Published: August 2019

Aromatic plants have a long and significant history in the traditional medicine of many countries. Nowadays, there is an increasing interest in investigating the biological properties of aromatic plant extracts mainly due to their diversity, high availability, and low toxicity. Greece is abundant in aromatic plants, which can be attributed to the country’s geographical position, the morphology of its landscape, and its numerous mountainous and insular areas. In the past 15 years, a number of aromatic plant extracts of Greek origin have been studied for their bioactivities, including their antiproliferative potential against different types of cancer. Although the pharmacological activities of specific species of Greek origin have been reviewed before, no gathered information on explicitly Greek species exist. In this review, we summarize existing data on the antiproliferative activity of extracts isolated from Greek aromatic plants and discuss their molecular mode(s) of action, where available, in order to identify promising extracts for future research and link chemical constituents responsible for their activity. We conclude that essentials oils are the most frequently studied plant extracts exhibiting high diversity in their composition and anticancer potential, but also other extracts appear to be worthy of further investigation for cancer chemoprevention.
Temporal Label Walk for Community Detection and Tracking in Temporal Network

Published: August 2019

The problem of temporal community detection is discussed in this paper. Main existing methods are either structure-based or incremental analysis. The difficulty of the former is to select a suitable time window. The latter needs to know the initial structure of networks and the changing of networks should be stable. For most real data sets, these conditions hardly prevail. A streaming method called Temporal Label Walk (TLW) is proposed in this paper, where the aforementioned restrictions are eliminated. Modularity of the snapshots is used to evaluate our method. Experiments reveal the effectiveness of TLW on temporal community detection. Compared with other static methods in real data sets, our method keeps a higher modularity with the increase of window size.

Published: August 2019

Refrigeration oil has a large effect on the performance of refrigeration systems. However, the physical and chemical indexes of fresh refrigeration oils often fail to reflect the actual operating characteristics, especially with respect to the degradation of refrigeration oils. In this paper, a bench evaluation test of refrigeration oils was carried out to investigate the degradation of synthetic refrigeration oils used with the refrigerant R134a, in a purpose-built, full-scale refrigeration system utilizing a screw compressor. To accelerate the degradation process of the refrigeration oil, the discharge temperature at the exit of the compressor was turned to a high level. Comparison tests of a mature refrigeration oil type A and a newly developed oil type B were performed under the same working conditions with 500 h of operating time. The performance of the screw compressor and refrigeration system was analyzed. The abrasion of the screw rotors and carbon deposition at the discharge port was investigated. Results showed that the bench evaluation test successfully predicted the degradation process of the refrigeration oils. The evolution analysis of the refrigeration oil viscosity and acid value during the bench evaluation test indicated that 15% of the physical and chemical indexes for refrigeration oil drain were too strict. Research work in this paper showed a more practical method to evaluate the performance of refrigeration oils through the bench evaluation test.
Simulation Study of Low-Velocity Impact on Polyvinyl Butyral Laminated Glass Based on the Combined TCK-JH2 Model
Authors: Wei Demin , Li Dong , Zhang Zongheng
Published: August 2019

In this paper, both experimental tests and numerical simulations of Polyvinyl Butyral (PVB) laminated glass pane under low-speed impact were carried out. In order to accurately predict the responses of annealed glass under low-speed impact, a constitutive model combined of the Taylor–Chen–Kuszmaul (TCK) model and the Johnson-Holmquist Ceramic (JH2) model is proposed. In order to describe the tensile damage characteristic of annealed glass, a rate-dependent TCK model is employed. The JH2 model is adopted when the glass material is under compression. The velocity and force of impactor, deflection of central point of glass pane, and the cracking pattern are studied to verify the combined TCK-JH2 model. Furthermore, the effects of the thickness of glass layer and PVB interlayer are investigated.
Preliminary Study on Greywater Treatment Using Nonwoven Textile Filters
Authors: Spychała Marcin , Nguyen Thanh Hung
Published: August 2019

The objective of the study was to evaluate the usefulness of novel nonwoven textile filter technology for greywater treatment. This technology had already been used on a lab scale for septic tank effluent treatment; however, this study is the first time it has been used for greywater treatment. The set-up period with septic tank effluent (STE) feeding was significantly shorter than that of greywater feeding. The average capacities of both filter types were practically the same: 1.0–1.4 cm d−1. The relatively high efficiencies of chemical oxygen demand (CODCr) and biochemical oxygen demand (BOD5) removal (58.8–71.6% and 56.7–79.8%, respectively) were obtained thanks to the relatively low filtration velocity and effective diffusion of atmospheric air into the greywater. The relatively high efficiency of total suspended solids (TSS) removal (67.0–88.4%) was obtained by reducing the effective pore size of the filtration layer due to high biomass concentration and accumulation of suspended solids. Thanks to hydrostatic pressure, the filters can work practically with very low energy consumption. The pollutants removal efficiencies were satisfactory in respect to simple construction and maintenance, low investment and operational costs.

Authors: Abdullah Nor Azliana , Abd Rahim Nasrudin , Gan Chin Kim , Nor Adzman Noriah
Published: August 2019

Solar power generation deals with uncertainty and intermittency issues that lead to some difficulties in controlling the whole grid system due to imbalanced power production and power demand. The forecasting of solar power is an effort in securing the integration of renewable energy into the grid. This work proposes a forecasting model called WT-ANFIS-HFPSO which combines the wavelet transform (WT), adaptive neuro-fuzzy inference system (ANFIS) and hybrid firefly and particle swarm optimization algorithm (HFPSO). In the proposed work, the WT model is used to eliminate the noise in the meteorological data and solar power data whereby the ANFIS is functioning as the forecasting model of the hourly solar power data. The HFPSO is the hybridization of the firefly (FF) and particle swarm optimization (PSO) algorithm, which is employed in optimizing the premise parameters of the ANFIS to increase the accuracy of the model. The results obtained from WT-ANFIS-HFPSO are then compared with several other forecasting strategies. From the comparative analysis, the WT-ANFIS-HFPSO showed superior performance in terms of statistical error analysis, confirming its reliability as an excellent forecaster of hourly solar power data.

Authors: Liu Yue , Meng Guoying , Suo Shuangfu , Li Dong , Wang Aiming , Cheng Xiaohan , Yang Jie
Published: August 2019

Spring failure is one of the critical causes of the structural damage and low screening efficiency of mining vibrating screens. Therefore, spring failure diagnosis is necessary to prompt maintenance for the safety and reliability of mining vibrating screens. In this paper, a spring failure diagnosis approach is developed. A finite element model of mining vibrating screens is established. Simulations are carried out and the spring failure influence rules of spring failure on the dynamic characteristics of mining vibrating screens are obtained. These influence rules indicate that the amplitude variation coefficients (AVCs) of the four spring seats in the x, y, and z directions can reveal two kinds of single spring failure and four kinds of double spring failure, which are useful for diagnosing spring failure. Furthermore, experiments are conducted. Comparison analyses of the experimental results and simulation results indicate that the proposed approach is capable of revealing various kinds of spring failure. Therefore, this approach provides useful information for diagnosing spring failure and guiding technical staff to routinely maintain mining vibrating screens.

Published: August 2019

Personal control over various indoor environment parameters, especially in the last decades, appear to have a significant role on occupants’ comfort, health and productivity. To reveal this complex relationship, 7441 occupants of 167 recently built or retrofitted office buildings in eight European countries participated in an online survey about personal/health/work data as well as physical/psycho-social information. The relationship between the types of control available over indoor environments and the perceived personal control of the occupants was examined, as well as the combined effect of the control parameters on the perceived comfort using multilevel statistical models. The results indicated that most of the occupants have no or low control on noise. Half of the occupants declared no or low control on ventilation and temperature conditions. Almost one-third of them remarked that they do not have satisfactory levels of control for lighting and shading from sun conditions. The presence of operable windows was shown to influence occupants’ control perception over temperature, ventilation, light and noise. General building characteristics, such as floor number and floor area, office type, etc., helped occupants associate freedom positively with control perception. Combined controlling parameters seem to have a strong relation with overall comfort, as well as with perception regarding amount of privacy, office layout and decoration satisfaction. The results also indicated that occupants with more personal control may have less building-related symptoms. Noise control parameter had the highest impact on the occupants’ overall comfort.

The depth of water is of great significance to the safe navigation of unmanned surface vehicles (USV)in shallow waters, such as islands and reefs. How to consider the influence of depth on the safety of USV navigation and path planning is relatively rare. Under the condition of ocean disturbance, the hydrodynamic characteristics of unmanned surface vehicles will affect its draft and depth safety. In this paper, the hydrodynamic model of unmanned surface vehicles is analyzed, and a water depth risk level A* algorithm (WDRLA*) is proposed. According to the depth point of the electronic navigation chart (ENC), the gridding depth can be obtained by spline function interpolation. The WDRLA* algorithm is applied to plan the path, which takes hydrodynamic characteristics and navigation errors into account. It is compared with the traditional A* shortest path and safest path. The simulation results show that the WDRLA* algorithm can reduce the depth hazard of the shortest path and ensure the safety of navigation.

We present results of the studies of internal gravity waves based on altitude-time dependences of the temperature and the density of the neutral component and the velocity of the vertical plasma motion at altitudes of the lower ionosphere (60–130 km). The vertical plasma velocity, which in the specified altitude range is equal to the velocity of the neutral component, the temperature, and the density of the neutral atmosphere are determined by the method of the resonant scattering of radio waves by artificial periodic irregularities (APIs) of the ionosphere plasma. We have developed an API technique and now we are evolving it for studying the ionosphere and the neutral atmosphere using the Sura heating facility (56.1 N; 46.1 E), Nizhny Novgorod, Russia. An advantage of the API technique is the opportunity to determine the parameters of the undisturbed natural environment under a disturbance of the ionosphere by a field of powerful high frequency radio waves. Analysis of altitude-time variations of the neutral temperature, the density, and the vertical plasma velocity allows one to estimate periods of atmospheric waves propagation. Wavelike variations with a period from 5 min to 3 h and more are clearly determined.
Are Inositol Polyphosphates the Missing Link in Dynamic Cullin RING Ligase Regulation by the COP9 Signalosome?
Authors: Zhang Xiaozhe , Rao Feng
Published: August 2019

The E3 ligase activity of Cullin RING Ligases (CRLs) is controlled by cycles of neddylation/deneddylation and intimately regulated by the deneddylase COP9 Signalosome (CSN), one of the proteasome lid-CSN-initiation factor 3 (PCI) domain-containing “Zomes” complex. Besides catalyzing the removal of stimulatory Cullin neddylation, CSN also provides a docking platform for other proteins that might play a role in regulating CRLs, notably protein kinases and deubiquitinases. During the CRL activity cycle, CRL–CSN complexes are dynamically assembled and disassembled. Mechanisms underlying complex dynamics remain incompletely understood. Recently, the inositol polyphosphate metabolites (IP6, IP7) and their metabolic enzymes (IP5K, IP6K) have been discovered to participate in CRL–CSN complex formation as well as stimulus-dependent dissociation. Here we discuss these mechanistic insights in light of recent advances in elucidating structural basis of CRL–CSN complexes.

This paper presents focusing of microparticles in multiple paths within the direction of the flow using dielectrophoresis. The focusing of microparticles is realized through partially perforated electrodes within the microchannel. A continuous electrode on the top surface of the microchannel is considered, while the bottom side is made of a circular meshed perforated electrode. For the mathematical model of this microfluidic channel, inertia, buoyancy, drag and dielectrophoretic forces are brought up in the motion equation of the microparticles. The dielectrophoretic force is accounted for through a finite element discretization taking into account the perforated 3D geometry within the microchannel. An ordinary differential equation is solved to track the trajectories of the microparticles. For the case of continuous electrodes using the same mathematical model, the numerical simulation shows a very good agreement with the experiments, and this confirms the validation of focusing of microparticles within the proposed perforated electrode microchannel. Microparticles of silicon dioxide and polystyrene are used for this analysis. Their initial positions and radius, the Reynolds number, and the radius of the pore in perforated electrodes mainly conduct microparticles trajectories. Moreover, the radius of the pore of perforated electrode is the dominant factor in the steady state levitation height.

The adrenal medulla is composed predominantly of chromaffin cells producing and secreting the catecholamines dopamine, norepinephrine, and epinephrine. Catecholamine biosynthesis and secretion is a complex and tightly controlled physiologic process. The pathways involved have been extensively studied, and various elements of the underlying molecular machinery have been identified. In this review, we provide a detailed description of the route from stimulus to secretion of catecholamines by the normal adrenal chromaffin cell compared to chromaffin tumor cells in pheochromocytomas. Pheochromocytomas are adrenomedullary tumors that are characterized by uncontrolled synthesis and secretion of catecholamines. This uncontrolled secretion can be partly explained by perturbations of the molecular catecholamine secretory machinery in pheochromocytoma cells. Chromaffin cell tumors also include sympathetic paragangliomas originating in sympathetic ganglia. Pheochromocytomas and paragangliomas are usually locally confined tumors, but about 15% do metastasize to distant locations. Histopathological examination currently poorly predicts future biologic behavior, thus long term postoperative follow-up is required. Therefore, there is an unmet need for prognostic biomarkers. Clearer understanding of the cellular mechanisms involved in the secretory characteristics of pheochromocytomas and sympathetic paragangliomas may offer one approach for the discovery of novel prognostic biomarkers for improved therapeutic targeting and monitoring of treatment or disease progression.

Inflammation, characterized by high numbers of infiltrating leukocytes and a high HLA Class I expression, is associated with a bad prognosis in uveal melanoma (UM). We wondered whether mutations in GNA11 or GNAQ differentially affect inflammation and HLA expression, and thereby progression of the disease. We analyzed data of 59 primarily enucleated UM eyes. The type of GNAQ/11 mutation was analyzed using dPCR; chromosome aberrations were determined by Fluorescence in Situ Hybridization (FISH), karyotyping, and single nucleotide polymorphism (SNP) analysis, and mRNA expression by Illumina PCR. Comparing tumors with a GNAQ mutation with those with a GNA11 mutation yielded no significant differences in histopathological characteristics, infiltrate, or HLA expression. When comparing the Q209L mutations with Q209P mutations in tumors with monosomy of chromosome 3, a higher mitotic count was found in the Q209P/M3 tumors (p = 0.007). The Kaplan-Meier (KM) curves between the patients of the different groups were not significantly different. We conclude that the type (Q209P/Q209L) or location of the mutation (GNA11/GNAQ) do not have a significant effect on the immunological characteristics of the tumors, such as infiltrate and HLA Class I expression. Chromosome 3 status was the main determinant in explaining the difference in infiltrate and HLA expression.
