Abstract (sommario):

Without variation we cannot speak and write. Language is necessary to communicate with others. Language needs words and words are made up of letters. All these together frame a sentence. So, a sentence gets its life through differentiation. There are eight such differentiations. They are I, Odu, Ku, In, Athu, Kan and Vili. The ability to express the differentiation in the text is called ‘differentiate unconsciousness’. It is about the system that differs based on the eight-differentiation mentioned above and a series of systems that are not differentiated. The differentiation in the form of difference is changed into series of differences by differentiating the differences from the active object to the spatial object. In this case, all the words that refer to the nature of an object and its displacement are considered as verbs. Thus, it is separated and isolated and that is its differentiation. This article is based on the comparison of the text materials of Tholkappiyam written by the text editors

Abstract (sommario):

Background: Human mesenchymal stem cells (hMSCs) have shown their multipotential including differentiating towards endothelial and smooth muscle cell lineages, which triggers a new interest for using hMSCs as a putative source for cardiovascular regenerative medicine. Our recent publication has shown for the first time that purinergic 2 receptors are key players during hMSC differentiation towards adipocytes and osteoblasts. Purinergic 2 receptors play an important role in cardiovascular function when they bind to extracellular nucleotides. In this study, the possible functional role of purinergic 2 receptors during MSC endothelial and smooth muscle differentiation was investigated. Methods and Results: Human MSCs were isolated from liposuction materials. Then, endothelial and smooth muscle-like cells were differentiated and characterized by specific markers via Reverse Transcriptase-PCR (RT-PCR), Western blot and immunochemical stainings. Interestingly, some purinergic 2 receptor subtypes were found to be differently regulated during these specific lineage commitments: P2Y4 and P2Y14 were involved in the early stage commitment while P2Y1 was the key player in controlling MSC differentiation towards either endothelial or smooth muscle cells. The administration of natural and artificial purinergic 2 receptor agonists and antagonists had a direct influence on these differentiations. Moreover, a feedback loop via exogenous extracellular nucleotides on these particular differentiations was shown by apyrase digest. Conclusions: Purinergic 2 receptors play a crucial role during the differentiation towards endothelial and smooth muscle cell lineages. Some highly selective and potent artificial purinergic 2 ligands can control hMSC differentiation, which might improve the use of adult stem cells in cardiovascular tissue engineering in the future.

Abstract (sommario):

Controlling mobility and borders has become a central, defining feature of the state today. Using the Norwegian welfare state as a case study, I argue that the differentiation of rights depending on status categories is an important way in which the state deals with irregular migration. It is also an integral element of border construction and how mobility is managed. How is the Norwegian welfare state differentiating the rights to work, health care, and economic welfare benefits and through which argumentations does the state legitimate these differentiations? This article argues that the practice of differentiation contributes to establishing hierarchies of belonging and enforces the nexus of welfare rights–migration management. Further, the exclusion of certain categories of people from accessing basic welfare services and, consequently, creating precarious lives, is legitimized by the discourse of humanitarian exceptionalism, through which migrants gain some support outside the welfare state system. This facilitates policies and regulations that are “tough on migration”, and produces the irregular subject as apolitical, a victim, and unwanted. The differentiation of rights and the discourses that the state uses to legitimate these differentiations are keys in the negotiation of who should be entitled to which rights in the future.

Abstract (sommario):

Very little is known about early molecular events triggering epithelial cell differentiation. We have examined the possible role of tyrosine phosphorylation in this process, as observed in cultures of primary mouse keratinocytes after exposure to calcium or 12-O-tetradecanoylphorbol-13-acetate (TPA). Immunoblotting with phosphotyrosine-specific antibodies as well as direct phosphoamino acid analysis revealed that induction of tyrosine phosphorylation occurs as a very early and specific event in keratinocyte differentiation. Very little or no induction of tyrosine phosphorylation was observed in a keratinocyte cell line resistant to the differentiating effects of calcium. Treatment of cells with tyrosine kinase inhibitors prevented induction of tyrosine phosphorylation by calcium and TPA and interfered with the differentiative effects of these agents. These results suggest that specific activation of tyrosine kinase(s) may play an important regulatory role in keratinocyte differentiation.

Abstract (sommario):

Multilocus measures of differentiation taking into account gametic disequilibrium are developed. Even if coupling and repulsion heterozygotes cannot be separated at the multilocus level, a method is given to calculate a composite measure of differentiation (CFst) at the zygotic level, which accounts for allelic associations combining both gametic and nongametic effects. Mean and maximum differentiations may be relevant when multilocus measures are computed. Maximum differentiation is the highest eigenvalue of the Fst matrix, whereas mean differentiation corresponds to the mean value of all eigenvalues of the Fst matrix. Gametic disequilibrium has a stronger effect on maximum differentiation than on mean differentiation and takes into account the anisotropy that may exist between within- and between-population components of disequilibria. Multilocus mean and maximum differentiation are calculated for a set of 81 Quercus petraea (sessile oak) populations assessed with eight allozyme loci and two phenotypic traits (bud burst and height growth). The results indicate that maximum differentiation increases as more loci (traits) are considered whereas mean differentiation remains constant or decreases. Phenotypic traits exhibit higher population differentiation than allozymes. The applications and uses of mean and maximum differentiations are further discussed.

Abstract (sommario):

This study investigates product differentiation, both in vertical and horizontal dimensions, in the instant noodles industry. It first presents theoretical models that predict firms' product differentiation behaviour before testing the theories using the case of instant noodles industries in three Asian countries: Indonesia, India, and Japan. The vertical differentiation behaviour is examined using the ANOVA test followed by the Bonferroni correction to investigate which brands exhibit the most evident vertical differentiation behaviour. The horizontal differentiation strategy is explored using a descriptive analysis method. Using information on the selling prices and product variants of instant noodles leading brands in each country, the empirical findings confirm the models' predictions. The study claims that companies apply the principles of 'minimum differentiation' as their vertical differentiation strategy and 'maximum differentiation' when differentiating horizontally. These strategies are implemented by choosing prices close to each other and producing distinguishable variants from competitors. These findings bring the theories of product differentiation into a real-life application and provide insights into how firms in the food products industry behave in differentiating their products.

Abstract (sommario):

Abstract The human AML-193 cell line requires exogenous granulocyte-monocyte colony-stimulating factor (GM-CSF) or interleukin-3 (IL-3) for growth in liquid or semisolid medium. However, these CSFs do not stimulate the differentiation of the cell line. We show that addition of all-trans retinoic acid (RA) or 1,25 dihydroxyvitamin D3 (D3) induces AML-193 cells to differentiate into the granulocytic or monocytic lineage, respectively. On the other hand, addition of either G- or M-CSF alone exerts virtually no differentiative effect. Terminal granulocytic or monocytic differentiation was observed when AML-193 cells were treated with RA and G-CSF, or D3 and M-CSF, respectively, as evaluated by cell morphology, analysis of surface antigens, and phagocytic functions. These positive interactions indicate that the differentiating activity of G- and M-CSF on leukemic cells may be unmasked by preliminary treatment with RA and D3, respectively, ie, the physiologic inducers override the leukemic differentiation blockade and CFSs exert their differentiative activity on the unblocked leukemic cells. These preliminary observations on a single cell line may pave the way for the designing of clinical protocols combining physiologic inducer(s) and hematopoietic growth factor(s) in the treatment of acute leukemia.

Abstract (sommario):

When studying how companies differentiate from their competitors, corporate image can play a main role in this aspect. The aim of this study is to observe and analyse the perception by the consumers of the corporate image of two groceries companies.This perception can lead to a competitive position in the marketplace by outperforming competitors in all the areas of corporate image. Thus, it can be observed how both companies are differentiated in the mind of the consumers in a different way.

Abstract (sommario):

The term differentiation has been widely used within education. This study makes use of the author's professional experience and a literature review to present a model of differentiation in practice; it seeks to suggest ways in which teachers' skills can be enhanced. The study aims to give an understanding of how teachers differentiate; what that say they do; and what can be described as good practice. Together with the wide ranging review of the literature, it draws upon field research, interviews, questionnaires, an analysis of OfSTED inspection reports and the author's experiences of running staff development courses on differentiation. It also includes work published by the author. The study is an original presentation of a comprehensive review about differentiation from the perspectives of the literature and serving teachers and contributes to the debate upon the methodological approaches to the study of the development of teaching skills. Conclusions are offered based upon an analysis and a discussion of these sources.

Abstract (sommario):

The inability of a plant to run from danger or seek nutrients necessitates its capacity to change the environment of the surrounding soil for protection and sustenance. A unique plant process, the release of thousands of autonomous cells from the root cap, called root border cells, may play a role in the ability of the plant to regulate microbial populations and nutrient availability in the rhizosphere. In this study, evidence is presented showing that root border cells are a differentiated tissue, that the production of border cells is highly regulated and tied to cell turnover in the root cap and that products of border cells regulate cell division in the root cap meristem. In vivo labeling experiments demonstrate that 13% of the proteins that are abundant in preparations from border cells are undetectable in root tip cells. Differences between the two cell populations are apparent as soon as border cells separate from each other, even when they are still adhered to the root tip. Twenty-five percent of the proteins synthesized by border cells in a 1-hour period are rapidly excreted into the incubation medium. Border cells arise within the root cap meristem by cell division and their production is tightly regulated both developmentally and in response to border cell removal. Removal of border cells results in the induction of cell division in the transverse root cap meristem to 400% of the basal rate within 30 minutes. This elevated rate of mitosis is maintained for 1.5 h and falls to basal levels within 6 hours. During this time, mitosis in the root apical meristem remains constant. mRNA differential display analysis showed changes in gene expression in the root cap within 5 to 15 minutes of removal of border cells. Genes putatively involved in cell functions in three regions of the cap showed expected distribution patterns by in situ hybridization and RNA blot analysis revealed changes in their expression patterns were seen in response to border cell removal. The presence of border cells acts as an inhibitor to continued mitosis and border cell production in the root cap. Evidence from fractionation studies shows that a heat stable, protease insensitive molecule in the range of 25 to 80 kDa, produced by the border cells themselves, is responsible for this inhibition.

Abstract (sommario):

Embryonic stem cells (ESCs) have the potential to differentiate into all somatic cell types and are uniquely capable of differentiating into functional cardiomyocytes; however, to effectively use ESCs for cell-based therapies to regenerate viable myocardial tissue, an improved understanding of mechanisms regulating differentiation is necessary. Currently, application of exogenous factors is commonly attempted to direct stem cell differentiation; however, progression towards controlling multiple environmental factors, including biochemical and mechanical stimuli, may result in increased differentiation efficiency for clinical applications. Additionally, current methods of ESC differentiation to cardiomyocytes are labor-intensive and produce relatively few cardiomyocytes based on initial ESC densities. Rotary suspension culture to produce embryoid bodies (EBs) has been shown to yield greater numbers of differentiating ESCs than static suspension cultures [1]. Thus, the objective of this study was to examine how the hydrodynamic mixing conditions imposed by rotary orbital culture modulate cardiomyocyte differentiation.

Abstract (sommario):

Mesenchymal stem cells (MSCs), derived from bone marrow stroma, are a promising source for tissue repair and regeneration, due to their excellent abilities for proliferation and multipotent differentiation. While accumulated evidences during the past decade have shown that MSCs are able to differentiate into osteoblasts, chondrocytes, myoblasts and adipocytes, more recent research suggest their potential in neuronal differentiation [1]. Chemical stimuli, including growth factors, hormones, and other regulatory molecules, are used traditionally to direct MSC differentiation. Our group has previously shown that the intracellular second messenger, cAMP, is able to initiate early phase neuron-like morphology changes and late phase neural differentiation in MSCs [2]. Studies using chemical stimuli alone, however, have shown limited success in differentiating MSCs to mature neurons, thereby suggesting other factors are necessary for this process. In recent years, interest has grown on the impact of mechanical stimulation, such as stiffness, surface topography, and mechanical stretching, on cell fate decision [3].

An optical tracking novelty filter that performs the process of optical image differentiation using an interferometric arrangement involving BaTiO3 has recently been demonstrated [1]. This device exploits differential optical phase changes and is therefore restricted to highlighting or tracking phase objects only. Other schemes for coherent optical image differentiation based on two beam coupling in BaTiO3 have also been demonstrated [2, 3]. These two devices rely on destructive interference between reference and signal beams under static conditions but require high optical quality for the BaTiO3 crystal so that the transmitted images do not suffer from any spatial distortion. In this paper we report a novel arrangement for optical differentiation of images in time that uses an optical processor based on the spatial frequency dependent response time of photorefractive Bi12SiO20 in a phase conjugate Michelson interferometric configuration. The device is capable of differentiating both amplitude and phase objects. To our knowledge this is the first time that BSO with its inherent fast response time, some two or three orders of magnitude faster than BaTiO3, has been used for such optical differentiation in time.

Abstract (sommario):

Recent evidence suggests that stem cell differentiation can be regulated by modulation of the cell’s biomechanics. The cytoskeletal structures and arrangements in stem cells undergoing differentiation are dramatically altered, and these alterations vary by lineage. The complexity of events associated with the transformation of these precursor cells leaves many questions unanswered about morphological, structural, proteomic, and functional changes in differentiating stem cells. A thorough understanding of stem cell behavior, both experimentally and computationally, would allow for the development of more effective approaches to the expansion of stem cells in vitro and for the regulation of their commitment to a specific phenotype.

Abstract (sommario):

Review question / Objective: To determine the utility of CEUS in the preoperative differentiation between pleomorphic adenomas (PAs) and Warthin’s tumors (WTs) of the parotid gland. Condition being studied: Recently, contrast-enhanced ultrasound (CEUS) has become a promising tool in distinguishing benign from malignant parotid gland tumors. However, its usefulness in differentiating various benign parotid tumors has not been determined so far. The preoperative differentiation of the most common parotid gland tumors (PAs and WTs) remains crucial to select an appropriate management strategy. Therefore, the purpose of the present study was to systematically review the literature to determine the utility of CEUS in the differentiation of PAs and WTs of the parotid gland.
