On Remedying the Presence of Heteroscedasticity in a Multiple Linear Regression Modelling
Authors: U. O. Emmanuel , C. I. Victor
Published: June 2024

This study demonstrated the very essence of remedying the presence of heteroscedasticity, where it existed, in regression modelling. Two different hypothetical data, Data A (the Original) and Data B (the Original), were used in this study for the purpose of illustration. The normality, multicollinearity and autocorrelation assumptions were satisfied, but the Breusch-Pagan test and the White test established the existence of heteroscedasticity in the two datasets. The estimated multiple linear regression model for Data A (the Original) was statistically significant with an R-square value of 0.976, an AIC value of 332.5929, and an SBC value of 347.2533; and the one for Data B (the Original) was also statistically significant with an R-square value of 0.553, an AIC value of 69.89669, and an SBC value of 82.15499. The Log-transformation was applied on the variables in Data A (the Original) and Data B (the Original) to give rise to new sets of data, Data A (Now with Heteroscedasticity Remedied) and Data B (Now with Heteroscedasticity Remedied); which equally satisfied the normality, multicollinearity and autocorrelation assumptions, and also satisfied that there were no existences of heteroscedasticity in the two datasets. Now, the estimated multiple linear regression model for Data A (Now with Heteroscedasticity Remedied) was statistically significant with an R-square value of 0.986, an AIC value of -135.021, and an SBC value of -120.361; and the estimated model for Data B (Now with Heteroscedasticity Remedied) was statistically significant with an R-square value of 0.624, an AIC value of -32.0801, and an SBC value of -19.8218. From the points of view of the values of the R-square (0.986>0.976 and 0.624>0.553), AIC (-135.021<332.5929 and -32.0801<69.89669) and SBC (-120.361<347.2533 and -19.8218<82.15499), it was evident that the estimated regression models for Data A (Now with Heteroscedasticity Remedied) and Data B (Now with Heteroscedasticity Remedied) were, respectively, better models when compared to the regression models for Data A (the Original) and Data B (the Original).
Prosodic Analysis of Noun Class Markers in the Syntax of BÀTỌ̀NU Language
Authors: A. Isaiah , S. A. Tella
Published: June 2024

The grammatical derivation of languages varies, leading to language specificity. In particular, languages with noun classes have unique methods of realizing them through prefixing and sometimes suffixing, such as in the Bàtọ̀nu language. This study focuses on the interface between syntax and phonology in the grammatical realization of the noun class system in the Bàtọ̀nu language, spoken in the Baruteen Local Government Area of Kwara State in Nigeria. Interviews were conducted to gather data, supplemented by secondary sources. Theoretical principles from Government and Binding Theory (GB) and Autosegmental Phonology were used to represent sentence structure and the tonal analysis of the data. Previous research established that the language has seven noun class markers (NCM). We found that phonological features, such as labialization, nasalization, and tone, can influence and determine the grammatical functions of class markers in languages that attest to them. In the case of Bàtọ́nu NCM, the tone is the determining factor. We assume that the class markers are unmarked at the underlying representation (UR), and when a floating high tone (HT) is assigned to the NCM underlyingly, they function as class markers. When a floating mid-tone (MT) is assigned, they become relative clause marker variants, and when in contact with the HT focus morpheme -á in focus constructions in the language, they function as focus marker variants.

Bryophaenocladius adigensis sp. n., a new species from the Italian Alps (Chironomidae, Orthocladiinae)
Authors: Moubayed Joel , Lencioni Valeria
Published: June 2024

Bryophaenocladius adigensis sp. n., is diagnosed and described based on two male adults material collected in the Sardagna stream, near the city of Trento (Northern Italy). Although the male of B. adigensis sp. n. shows some morphological affinities with other Bryophaenocladius species (B. aestivus, B. flexidens, B. muscicola, B. subvernalis and B. thaleri), it exhibits a combination of unique characters that make it a different species: palpomere 3 with 3 typical sensilla coeloconica; absence of antepronotal setae; antennal ratio= 0.86; tergite IX and anal point without lateral expansion; aedeagal lobe typically sub-oval; virga consisting of 2 curved unequal spines; distal part of gonocoxite with a vertical row of setae; inferior volsella, long nose-like shaped, distal part spatulate with 2 characteristic pre-apical setae, median part bare. Currently, about 42 Bryophaenocladius species are reported from Europe, of which only 11 are known from Italy. Consequently, the description here of B. adigensis sp. n. increases the total number in the genus to 12 from this country. Based on type-locality features, we can consider B. adigensis sp. n. as typical of mountain streams fed mainly by groundwater.

A desvalorização, a exposição a longas jornadas de trabalho, recursos escassos e demandas psicológicas, são moduladores para a saúde, que impactam o indivíduo em sua dimensão biopsicossocial, suas relações interpessoais e o corpo social como um todo. Nesse sentido, o objetivo do estudo é descrever os fatores predisponentes que irão impactar na saúde mental de docentes universitários no contexto laboral e social. Trata-se de uma revisão sistemática da literatura, com levantamento bibliográfico por meio de buscas e seleções de publicações de artigos científicos e revistas eletrônicas, como a Biblioteca Virtual de Saúde (BVS) e National Library of Medicine (PubMed) no período de 2018 a 2022, nos idiomas inglês, espanhol e português. São eles: Saúde Mental (Mental Health), Professor Universitário (College Professor), Qualidade de vida (Quality of Life), Fatores Predisponentes (Predisposing Factors), todos foram combinados com o uso dos operadores booleanos “AND” e “OR”. Em um total de 26 artigos, apurou-se que a saúde docente tem natureza tripla, (biológica, psicológica e social), moldada pelo trabalho. Desta forma existem diversos fatores que podem interferir na qualidade de vida destes profissionais. Notou-se que não há programas específicos voltados para promoção de saúde desses trabalhadores, sendo essencial que as instituições promovam e mantenham um ambiente de trabalho saudável, quanto às estratégias pessoais, intervindo com maneiras de prevenção e promoção da saúde.
Avaliação química de couve-manteiga (Brassica oleracea) submetida à adição de revestimento à base de amido
Authors: Fernandes Ítala Maiara Vieira , Guimarães Claudinei Martins , Carvalho Vania Silva
Published: June 2024

A couve-manteiga (Brassica oleracea) é uma hortaliça importante para os agricultores brasileiros devido à sua resistência às oscilações de temperatura, o que permite sua disponibilidade durante todo o ano. Esta hortaliça é altamente consumida, pois contém propriedades nutracêuticas e baixo teor calórico, no entanto, possui vida útil limitada, resultando em perdas devido à falta de tratamentos, embalagens e armazenamento adequados. Estudos têm explorado o uso de biopolímeros à base de amido para aumentar a vida útil pós colheita de frutas. No entanto, ainda não há pesquisas sobre a utilização desses biopolímeros na preservação da couve-manteiga. Assim, a presente pesquisa teve como objetivo avaliar a qualidade pós-colheita da couve-manteiga in natura e minimamente processada, utilizando revestimento à base de amido. O experimento foi conduzido na Embrapa Hortaliças, em Brasília, DF, Brasil e no Instituto Federal Goiano, Campus Morrinhos, GO, Brasil. Utilizou-se o delineamento experimental em blocos casualizados, com 4 repetições. Os tratamentos foram compostos de amostras de folhas inteiras e minimamente processadas, submetidas ao revestimento de amido após sanitização e uma amostra, sem aplicação do revestimento, para fins de comparação (testemunha). As amostras foram armazenadas sob refrigeração e avaliadas quanto a umidade, cinzas, vitamina C, clorofila a, clorofila b, pH, compostos fenólicos e capacidade antioxidante, a cada três dias durante doze dias. Os dados foram submetidos à ANOVA e teste tukey, a 5% de probabilidade. Os resultados indicaram que não houve diferença significativa entre as amostras quanto ao pH e que o revestimento foi eficaz na manutenção das propriedades antioxidantes, nutracêuticas e físico-químicas das couves inteiras e minimamente processadas por até 6 dias de armazenamento. Assim, a aplicação do revestimento é eficiente na conservação da couve-manteiga, oferecendo uma alternativa viável para prolongar sua vida útil sem comprometer a qualidade.

Published: June 2024

Parkinson's disease (PD) is the most common neurodegenerative disease after Alzheimer's disease. PD causes degenerative changes in the cerebellum. It is known that the cerebellum does not have a symmetrical anatomy and some pathological disorders may cause asymmetric changes in the cerebellum. In this study, our aim is evaluate whether or not cases with PD show age and gender dependent cerebellar changes and cerebellar asymmetry comparing with healthy subjects. We also aimed to depict the probable cortical thickness differences in cases with PD by using a stereological technique. The study evaluated the volumetric assesment of each cortical cerebellar hemisphere and total cerebellum by applying a stereological technique on magnetic resonance images. The age and gender-matched study was composed of 47 adult cases with PD and 47 healthy subjets as control. In the PD group, right and left cerebellar hemisphere volume, total cerebellum volume, and cortical thickness of the right and left cerebellar hemispheres were significantly lower than the control group (p<0.01). Although there was significant cerebellar atrophy and asymmetry in PD cases with age between 40-71, the study showed no statistically significant cerebellar asymmetry in cases over 70 years of age. However, no significant difference was detected depending on gender. Our findings suggest that in PD, cerebellum’s cortical thickness and volume decreases. The decrease in the volume and cortical thickness of the cerebellum increases with age, regardless of gender, compared to healthy individuals. However, this difference begins to close with age.
Study on Interdisciplinary Thematic Learning of Senior High School English based on Core Literacy
Authors: Yang Lingyu
Published: June 2024

With core literacy gradually becoming an important topic in the field of education, English teachers are also trying to practice and infiltrate core literacy into the design of teaching activities. Interdisciplinary is an educational activity that breaks the boundaries of disciplines and integrates theories or methods of different disciplines, which is helpful to the integration of subject knowledge. Starting from the significance and connotation of interdisciplinary thematic learning, this paper explores the application of interdisciplinary thematic learning in English courses and its help in cultivating core literacy. At the same time, this paper tries to give some suggestions on how to improve students' core literacy through interdisciplinary thematic learning, aiming at promoting students' core literacy to be better improved.
Far-Field Dipole Noise Extracted From Time-Resolved PIV Over Separated Aerofoils
Authors: Carter D. W. , Ganapathisubramani B.
Published: June 2024

We demonstrate far-field dipole acoustics from time-resolved planar particle image velocimetry (PIV) data for turbulent separated flow over NACA 0012 and NACA 65-410 aerofoils at a chord-based Reynolds number Re_c ≈ 71000. The efficacy of the pressure reconstructions is demonstrated through a comparison with RANS simulationsand surface pressure power spectra. The pressure reconstructions are used in combination with Curle's analogy to determine the far-field noise generation. The noise directivity is found to be determined mostly by the geometry, with similar overall sound power level for both aerofoils. Through use of the data-driven spectral Linear Stochastic Estimation (sLSE) technique, the turbulent structures most correlated to the farfield noise are identified. In transient stall conditions, the location of correlated structures suggests shear layer flapping as the dominant mechanism. In deep stall, the correlated structures are concentrated further downstream in proximity to the trailing edge.
Volumetric Lagrangian Particle Velocity And Temperature Measurements In Large Aspect Ratio Rayleigh-Bénard Convection
Authors: Käufer T. , Cierpka C.
Published: June 2024

Rayleigh-Bénard convection (RBC) is a well-known model experiment for temperature-driven flows. Even though RBC has been studied for decades, many open questions remain. Temporally and spatially resolved temperature and velocity data are crucial for a better understanding of the underlying physics. This paper proposes a new approach that combines Lagrangian Particle Tracking (LPT) with Particle Image Thermometry (PIT). The combined measurement techniques should be utilized to investigate the flow inside a large aspect ratio RBC cell with a lateral size of w = 700 mm and a height h = 28 mm, which corresponds to an aspect ratio of 25. Due to the large aspect ratio, the cameras observe the flow through the transparent cooling plate. We show that LPT of thermal convection flows within the setup can be performed successfully. Subsequently, we describe the temperature measurement technique PIT based on Thermochromic Liquid Crystals (TLCs) and discuss and quantify the additional challenge arising from color imaging of small particles. Namely, the sparse color sampling of a color filter array (CFA) camera and chromatic dispersion resulting from the oblique viewing angle of the color camera. To circumvent the sparse sampling of the CFA camera, we use a three-chip camera that resolves each color (red, green, blue) at full sensor resolution. We quantify the influence of the chromatic dispersion by cross-correlating the color channels. We then apply the resulting disparity maps in a correcting step to reduce the disparities by shifting the red and blue towards the green channel. The visual comparison of the corrected and uncorrected images shows a reduction in the color dispersion. Beyond that, the remaining disparities between the colors of the corrected images are minimal. This indicates that the correction step is useful to increase the quality of the particle images for temperature estimation.

Published: June 2024

This study examined the support mechanisms that are available to enhance the post-retirement well-being of Lagos State Civil Service retirees. Using the descriptive survey research design and the purposive/snowball sampling technique, 671 retirees were selected as respondents for this study. Collected and collated data were analyzed using descriptive statistical techniques such as tables, frequencies, and bar charts.  Four research questions were stated and findings from research question one revealed that the challenges faced by Lagos State Civil Service retirees encompass financial insecurity, health deterioration, loss of routine, emotional adjustment, lack of purpose, and social isolation. Equally, research question two found that most retirees rely strongly on pensions for financial security. Research question three brought to the fore that 98.4% of the respondents observed that the existing support mechanisms during the transition to retirement are not adequate at all, and research question four indicated that retirees want assistance in financial planning, improved healthcare, lifelong learning opportunities, a centralized information portal, active feedback mechanisms, and housing assistance. Based on these findings, this study concludes that the current support mechanisms are grossly inadequate underscores a critical gap between provided services and the actual needs of the retired populace. Thus, the study recommends amongst others that the Lagos State Civil Service should implement a multi-faceted approach that addresses the diverse needs (i.e., financial education, healthcare accessibility, mental health and social reintegration services, lifelong learning, and volunteer programmes and centralized information portal) of its retirees.
Patients’ satisfaction with the quality healthcare services
Authors: Milosavljević Tamara , Stoičević Nina , Ivanović Dragan
Published: June 2024

The quality of health services has become a priority in the modern health system, defined as a service that meets professional and patient needs by efficiently using resources and minimizing risks. The quality of health care implies the best possible outcomes, timely service, rational use of resources and application of appropriate procedures. Quality measurement includes dimensions such as availability, safety, continuity, effectiveness and interpersonal relationships, key to patient trust and satisfaction.
This literature review analyzes instruments for measuring the quality of health services and their importance for improving the system. 
Satisfaction is not a sufficient indicator of quality, because patients are often unaware of their real needs and may demand inadequate treatments. Quality also includes economy and compliance with legal, ethical and contractual obligations of the healthcare institution. Major satisfaction factors include healthcare, communication, waiting time and patient education. Patient satisfaction should be measured regularly and used for continuous improvement of services.
The quality of health care is a continuous process that requires constant monitoring, evaluation and improvement to ensure the best possible outcome for patients.

Published: June 2024

Cervical laminoplasty was initially introduced as an effective alternative to laminectomy procedures but advances in surgical techniques and perioperative protocols have allowed its use to expand. As the utilization of ambulatory surgical centers continues to grow, so too will the transition of mandatory inpatient procedures such as cervical laminoplasty to the outpatient setting. Successful transition of such involved procedures requires a host of adjustments to facilitate this change. This article reviews the key aspects of our medical practice that have enabled us to find success in the outpatient setting and outlines the potential for successful transition of cervical laminoplasty.

Rethinking Under-represented Ethnicities in ELT Materials through a Critical Discourse Analysis-oriented Model
Authors:   Benemérita Escuela Normal Veracruzana, Durand Sergio
Published: June 2024

English Language Teaching (ELT) materials are not only pedagogical sources, but they also actively build a vision of reality, often reproducing, legitimizing and perpetuating certain hegemonic discourses. Even if injustice and inequalities are denounced in some materials, global issues are just mentioned rather than problematized and discriminated ethnicities are commonly represented as passive entities with no voice or agency on their own issues. In this article, a model and its operationalization are proposed in order to depict how language teachers can write materials to fight back passive constructions embedded in ELT textbooks and build, through activities based on critical discourse analysis techniques, strong and combative representations of discriminated minorities. The model seeks to critically engage learners in discussing social inequalities and encourage further analysis on how, through language, underrepresented minorities resist and debunk power. First, some examples are given of how weak representations of minorities are portrayed in ELT materials. Secondly, the model, based on Gee's (2011) three-level definition and Macgilchrist's (2016) generative perspective of discourse analysis, is explained. Finally, two examples of the model are presented in order to show how passive constructions could be dismantled by giving a voice to silenced ethnicities that are either challenging power or fighting for recognition through text or talk.
Evolution of the definition of energy security and local component (clusters) in the theoretical perspective
Authors: Bałamut Anna , Ruszel Mariusz
Published: June 2024

Energy security is primarily associated with access to energy resources at an affordable price. Due to the increasing number of changes taking place in the environment, security should be perceived by states, entrepreneurs and local communities as a process that requires continuous cooperation of all its stakeholders in both the short and long term at the local, national and international level. It is therefore worth paying attention to energy clusters whose goal is to develop distributed energy, which serves to improve local energy security. In the face of the changing environment, local energy independence becomes more important. The initiative consists in generating, transmitting, storing and using energy locally. For this reason, the aim of the article is to answer the research questions: does today's view of energy security take into account the behavioral component? Do energy clusters, in terms of definition, take into account local actors, their interests, needs and opportunities? The article aims to verify the research hypothesis that energy clusters suggest the need to modify the definition of energy security taking into account the local component with its potential and social needs. The article can be a starting point for further analysis in the field of ensuring energy security at the local level. Key words: energy security, energy clusters, behavioral component, local component, Poland

The proposed development at Beaverbank Place, Canonmills, Edinburgh led to the excavation of the remains of the 19th-century Beaverbank Tannery. Accompanying historical research allowed the history of the ownership and tenancies of the buildings and various businesses to be traced from 1807 to 1959. This included the early 19th-century Clark’s Mill linen bleachers and the 1868 tannery built by the Johnston family and later leased by family firms of the Pringles and Walkers. A period of abandonment between 1913 and 1915 was followed by the repurposing of the building as a sawmill and cooperage. Part of the site changed again to become a motor garage in 1928.
The remains can be matched well with historic map evidence and appear to relate predominantly to the late 19th-century tannery structures. Remains were found of approximately 100 tanning pits set out in a grid pattern, with further features related to drainage, paving and other structures. Very little environmental or artefactual evidence was recovered to shed light on specific practices, materials used or materials produced.
There were also scant structural remains that could be related to the earlier linen bleachers and to the later motor garage.

Its potential to revolutionalise the chemical value chain, coupled with the associated supremely challenging scientific aspects, has ensured this topic’s high popularity over the preceeding decades. Herein, we report a non‐exhaustive account of the current developments within the field of oxidative methane upgrading and summarise the pertaining challenges that have yet to be solved.
Oceanobacillus indicireducens sp. nov., a facultative alkaliphile that reduces an indigo dye
Authors: Hirota Kikue , Aino Kenichi , Nodasaka Yoshinobu , Yumoto Isao
Published: July 2012

An indigo-reducing facultatively alkaliphilic and halophilic strain, designated strain A21T, was isolated from a fermented Polygonum indigo (Polygonum tinctorium Lour.) liquor sample aged for 4 days prepared in a laboratory. 16S rRNA gene sequence phylogeny suggested that strain A21T was a member of the genus

Oceanobacillus

with the closest relative being the type strain of

Oceanobacillus chironomi

(similarity: 96.0 %). The cells of the isolate stained Gram-positive and were facultatively anaerobic straight rods that were motile by peritrichous flagella. The strain grew between 18 and 48 °C with optimum growth at 39 °C. It grew in the pH range of 7–12. It hydrolysed casein, gelatin and Tween 20 but not Tweens 40, 60 and 80, starch or DNA. No isoprenoid quinone was detected and the DNA G+C content was 39.7 mol%. The whole-cell fatty acid profile mainly consisted of iso-C15 : 0, anteiso-C15 : 0 and C16 : 0. DNA–DNA hybridization experiments with

O. chironomi

revealed 13 % relatedness. Owing to the differences in phenotypic and chemotaxonomic characteristics, and phylogenetic analyses based on 16S rRNA gene sequences and DNA–DNA relatedness data from reported

Oceanobacillus

species, the isolate merits classification as a representative of a novel species, for which the name Oceanobacillus indicireducens sp. nov. is proposed. The type strain is A21T ( = JCM 17251T  = NCIMB 14685T). The description of the genus

Oceanobacillus

is also emended.

Published: July 2012

A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterial strain, designated WT-MW11T, was isolated from wood falls on the coast of Wando, an island of South Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain WT-MW11T grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2.0–3.0 % (w/v) NaCl. Bacteriochlorophyll a was not produced. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain WT-MW11T clustered with

Pseudorhodobacter ferrugineus

IAM 12616T and

Pseudorhodobacter aquimaris

HDW-19T, with which it exhibited 16S rRNA gene sequence similarity values of 97.9 and 95.5 %, respectively. Strain WT-MW11T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain WT-MW11T was similar to those of

P. ferrugineus

JCM 20687T and

P. aquimaris

HDW-19T. The DNA G+C content of strain WT-MW11T was 61.6 mol% and its mean DNA–DNA relatedness value with

P. ferrugineus

JCM 20687T was 12.3 %. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WT-MW11T was distinguishable from the two recognized species of the genus

Pseudorhodobacter

. On the basis of the data presented, strain WT-MW11T is considered to represent a novel species of the genus

Pseudorhodobacter

, for which the name Pseudorhodobacter wandonensis sp. nov. is proposed. The type strain is WT-MW11T ( = KCTC 23672T = CCUG 61506T). The description of the genus

Pseudorhodobacter

is emended.

Published: July 2012

1,2‐Dimethyl‐3‐(5‐methylisoxazol‐3‐yldiazenyl)‐1H‐indole was obtained by coupling 3‐amino‐5‐methylisoxazole with diazotised 1,2‐dimethylindole. It was characterised by proton and carbon nuclear magentic resonance, ultraviolet–visible, infrared and Raman spectra, and the X‐ray single crystal diffraction method. On the theoretical side, the molecular geometry, chemical shifts and the fundamental vibrational frequencies were evaluated using density functional theory. Time‐dependent density functional theory was used to evaluate the electronic excitation spectra. In addition, the scaled quantum mechanical approach was used to study the total energy distributions of the vibrational modes of the molecule. The results showed that the general agreement between experimental and calculated geometric parameters, chemical shifts and λmax values are good. Excellent agreement was found between the calculated and experimental vibrational frequencies.
ZipA Is Required for FtsZ-Dependent Preseptal Peptidoglycan Synthesis prior to Invagination during Cell Division
Authors: Potluri Lakshmi-Prasad , Kannan Suresh , Young Kevin D.
Published: July 2012

Rod-shaped bacteria grow by a repetitive cycle of elongation followed by division, and the mechanisms responsible for these two processes have been studied for decades. However, little is known about what happens during the transition between the two activities. At least one event occurs after elongation ends and before division commences, that being the insertion of new cell wall peptidoglycan into a narrowly circumscribed ribbon around midcell where septation is destined to take place. This insertion does not depend on the presence of the septation-specific protein PBP3 and is therefore known as
P
BP3-
i
ndependent
p
eptidoglycan
s
ynthesis (PIPS). Here we report that only FtsZ and ZipA are required to generate PIPS in wild-type
Escherichia coli
. PIPS does not require the participation of other members of the divisome, the MreB-directed cell wall elongation complex, alternate peptidoglycan synthases, the major peptidoglycan amidases, or any of the low-molecular-weight penicillin binding proteins. ZipA-directed PIPS may represent an intermediate stage that connects cell wall elongation to septal invagination and may be the reason ZipA is essential in the gammaproteobacteria.

Published: July 2012

Plants have been historically used for diabetes treatment and related anti-inflammatory activity throughout the world; few of them have been validated by scientific criteria. Recently, a large diversity of animal models has been developed for better understanding the pathogenesis of diabetes mellitus and its underlying inflammatory mechanism and new drugs have been introduced in the market to treat this disease. The aim of this work is to review the available animal models of diabetes and anti-inflammatory activity along with somein vitromodels which have been used as tools to investigate the mechanism of action of drugs with potential antidiabetic properties and related anti-inflammatory mechanism. At present, the rigorous procedures for evaluation of conventional antidiabetic medicines have rarely been applied to test raw plant materials used as traditional treatments for diabetes; and natural products, mainly derived from plants, have been tested in chemically induced diabetes model. This paper contributes to design new strategies for the development of novel antidiabetic drugs and its related inflammatory activity in order to treat this serious condition which represents a global public health problem.

Published: July 2012

In this study, we investigated the anti-angiogenic effect of the Chinese herbal decoction Danggui Buxue Tang (DBT;Radix AstragaliandRadix Angelicae sinensisin 5 : 1 ratio) in a rat model of liver fibrosis, in order to elucidate its mechanisms of action against liver fibrosis. Liver fibrosis was induced with CCl4and high-fat food for 6 weeks, and the rats were treated with oral doses of DBT (6 g raw herbs/kg/d) and N-Acetyl-L-cysteine (NAC; 0.1 g/kg/d). The results showed that both DBT and NAC attenuated liver fibrosis and neo-angiogenesis. Furthermore, DBT and NAC improved SOD activity but decreased MDA content and 8-OH-dG in fibrotic livers, with DBT being more effective than NAC. DBT decreased the expression of VEGF, Ang1 and TGF-β1 and their signaling mediators, whereas NAC had no effect on VEGF and VEGFR2 expression. Both DBT and NAC reduced HIF-1αgene and protein expression in fibrotic livers, with DBT being more effective. These data clearly demonstrate that the anti-fibrotic properties of DBT are related to its ability to inhibit angiogenesis and its anti-angiogenic mechanisms are associated with improving oxidative stress, regulating the expression and signaling of angiogenic factors, and especially modulating HIF-1αin fibrotic livers.

Authors: Archontogeorgis Kostas , Steiropoulos Paschalis , Tzouvelekis Argyris , Nena Evangelia , Bouros Demosthenes
Published: July 2012

Interstitial lung diseases (ILDs) represent a heterogeneous group of more than two hundred diseases of either known or unknown etiology with different pathogenesis and prognosis. Lung cancer, which is the major cause of cancer death in the developed countries, is mainly attributed to cigarette smoking and exposure to inhaled carcinogens. Different studies suggest a link between ILDs and lung cancer, through different pathogenetic mechanisms, such as inflammation, coagulation, dysregulated apoptosis, focal hypoxia, activation, and accumulation of myofibroblasts as well as extracellular matrix accumulation. This paper reviews current evidence on the association between lung cancer and interstitial lung diseases such as idiopathic pulmonary fibrosis, sarcoidosis, systemic sclerosis, dermatomyositis/polymyositis, rheumatoid arthritis, systemic lupus erythematosus, and pneumoconiosis.
Study of Tracer Diffusion Mechanism in Amorphous Metal
Authors: Kien P. H. , Hue H. V. , Hung P. K.
Published: July 2012

The statistical relaxation (SR) simulation has been conducted to study the behavior of simplexes and bubbles (BB) in amorphous Co metal containing 2×105 atoms. The simulation reveals that the fraction of 4-simplex increases and n-simplex (n>4) decreases depending upon relaxation degree. The simulation found that a large number of BB vary upon relaxation degree, which could play a role of diffusion vehicle for Co atoms in amorphous matrix. The idea of the diffusion mechanism in amorphous metal is described as follows: the elemental atomic movement includes a jump of neighboring atom into the BB and then a collective displacement of a large number of atoms around BB.

Published: July 2012

In patients with fibrotic idiopathic interstitial pneumonia (f-IIP), the diffusing capacity for carbon monoxide (DLCO) has been used to predict abnormal gas exchange in the lung. However, abnormal values for arterial blood gases during exercise are likely to be the most sensitive manifestations of lung disease. The aim of this study was to compare DLCO, resting PaO2, P(A-a)O2at cardiopulmonary exercise testing peak, and oxygen desaturation during a 6-min walk test (6MWT). Results were obtained in 121 patients with idiopathic pulmonary fibrosis (IPF,n=88) and fibrotic nonspecific interstitial pneumonias (NSIP,n=33). All but 3 patients (97.5%) had low DLCO values (<LLN) whereas only 66.6% had low KCO; 42 patients (65%) exhibited resting hypoxemia (<75 mmHg); 112 patients (92.5%) exhibited a high P[(A-a)O2], peak (>35 mmHg) and 100 (83%) demonstrated significant oxygen desaturation during 6MWT (>4%). Interestingly 27 patients had low DLCO and normal P(A-a)O2, peak and/or no desaturation during the 6MWT. The 3 patients with normal DLCO also had normal PaO2, normal P(A-a)O2, peak, and normal oxygen saturation during 6MWT. Our results demonstrate that in fibrotic IIP, DLCO better defines impairment of pulmonary gas exchange than resting PaO2, exercise P(A-a)O2, peak, or 6MWT SpO2.
