Within urbanized areas, the importance of neighborhood ponds should be assessed and investigated with its socio-spatial parameters (access and linkage, sociability, uses and activities, comfort and image etc) since such water bodies act as retention basin during floods, reservoir for lean period and responsive socializing agent to measure community interaction which are generally been neglected by city government, threatened by developers but taken care by neighborhood people in Old Dhaka. Most of the inner city small neighborhoods ponds have been encroached and filled up upon demand on land as the pond were not integrated in the city planning. The main objective of this research is to assess the significance of such water bodies and revive the spatial relationship of neighborhood ponds with its nearby residents. Therefore a socio-environmental survey (quantitative and qualitative) is held on neglected and threatened small neighborhood ponds of Old Dhaka with direct observation, in-depth interviews of the residents to compare the environmental, ecological and social contexts and explore the opportunities. An integrated assessment for enhancing sustainability and creating opportunities through community participation has been suggested to rejuvenate the ponds with attention for wetland preservation and to integrate into community development programs or planning.

Mast cells in the dura mater of the rat may play a role in cerebral pathologies including neurogenic inflammation (vasodilation; plasma extravasation) and headache pain . As has been suggested for other tissues, dural mast cells may exhibit a close spatial relationship to nerves. There has been no detailed ultrastructural description of mast cells in this tissue; therefore, the goals of this study were to provide this analysis and to determine the spatial relationship of mast cells to nerves and other components of the dura mater in the rat.Four adult anesthetized male Wistar rats (290-400 g) were fixed by perfusion through the heart with 2% glutaraldehyde and 2.8% paraformaldehyde in a potassium phosphate buffer (pH 7.4) for 30 min. The head of each rat was removed and stored in fixative for a minimum of 24 h at which time the dural coverings were removed and dissected into samples that included the middle meningeal vasculature. Samples were routinely processed and flat embedded in LX 112. Thick (1 um) sections from a minimum of 3 blocks per rat were stained with toluidine blue (0.5% aqueous).

This article discusses the struggles of urban social movements for a de-neoliberalisation of housing policies in Poulantzian terms as a “condensation of the relationship of forces”. Drawing on an empirical analysis of the “Berliner Mietenvolksentscheid” (Berlin rent referendum), which was partially successful in forcing the city government of Berlin to adopt a more progressive housing policy, the article argues that urban social movements have the capacity to challenge neoliberal housing regimes. However, the specific materiality of the state apparatus and its strategic selectivity both limit the scope of intervention for social movements aiming at empowerment and non-hierarchical decision-making.

This paper describes a methodological approach that is able to analyse socio-demographic and -economic data in large-scale spatial detail. Based on the two variables, population density and annual income, one investigates the spatial relationship of these variables to identify locations of imbalance or disparities assisted by bivariate choropleth maps. The aim is to gain a deeper insight into spatial components of socioeconomic nexuses, such as the relationships between the two variables, especially for high-resolution spatial units. The used methodology is able to assist political decision-making, target group advertising in the field of geo-marketing and for the site searches of new shop locations, as well as further socioeconomic research and urban planning. The developed methodology was tested in a national case study in Germany and is easily transferrable to other countries with comparable datasets. The analysis was carried out utilising data about population density and average annual income linked to spatially referenced polygons of postal codes. These were disaggregated initially via a readapted three-class dasymetric mapping approach and allocated to large-scale city block polygons. Univariate and bivariate choropleth maps generated from the resulting datasets were then used to identify and compare spatial economic disparities for a study area in North Rhine-Westphalia (NRW), Germany. Subsequently, based on these variables, a multivariate clustering approach was conducted for a demonstration area in Dortmund. In the result, it was obvious that the spatially disaggregated data allow more detailed insight into spatial patterns of socioeconomic attributes than the coarser data related to postal code polygons.

Abstract A 54-year-old man with a right hemiparesis was found to have an intrasellar intercarotid communicating artery associated with agenesis of the right internal carotid artery. Magnetic resonance imaging (MRI) studies demonstrated the spatial relationship of the anomalous artery to the surrounding structures, thus suggesting an embryonic enlargement of the capsular artery as a source of this anomalous artery.

In view of the inaccuracy of the traditional correlation analysis method, this paper proposes a correlation analysis method between the multifractal characteristics of regional landforms and the development of geological disasters. Firstly, the multifractal characteristics of regional landforms are described by using the basic fractal characteristics of self-similarity or scale invariance. Then the corresponding relation table is established according to the width of the fractal spectrum and the number of landslides and hidden dangers, and the spatial relationship of geological disaster development is analyzed. Combined with the above-mentioned spatial relationship of geological disaster development and the multifractal characteristic data of regional landforms, the correlation coefficient between the two is calculated to complete the correlation analysis between the multifractal characteristics of regional geomorphology and the development of geological disasters. The experimental results show that compared with the traditional correlation analysis method, the correlation analysis results of the multifractal characteristics of regional geomorphology and the development of geological disasters are more accurate.

In differentiating 3T3-L1 cells, lipid spheres, the endoplasmic reticulum (ER), microperoxisomes, and mitochondria form "constellations" that may reflect the interplay of lipid metabolizing enzymes in these organelles. ER cisternae are also situated very close to "rosettes,"plasmalemmal specializations found in mature adipocytes in vivo. As in hepatocytes and absorptive cells of the intestine, this spatial relationship of ER and plasmalemma suggests a role for rosettes in the uptake of exogenous lipid precursors. The morphological differentiation of 3T3-L1 preadipocytes includes the loss of "stress fibers" and the appearance of microfilament like structures that encase, in a complex manner, the cytosolic lipid spheres that appear during differentiation. Other features described for the first time in 3T3-L1 preadipocytes include: (a) the presence of an extensive acid phosphatase (AcPase) positive GERL from which coated vesicles apparently arise (these coated vesicles display AcPase activity and are much smaller and far more numerous than the coated vesicles that seem to arise from the plasmalemmal coated pits); (b) the abundance of AcPase-positive autophagic vacuoles; and (c) a high level of alpha-naphthyl-acetate-esterase activity which, by light microscopy cytochemistry, appears to be localized in the cytosol.

Abstract BACKGROUND Rapid early progression (REP) of glioblastoma after surgery observed on pre-radiotherapy MRI scan is common. Subventricular zone (SVZ) and hippocampal regions are supposed to harbor astrocyte-like neural stem cells (NSC) with tumors arising from these transformed stem cells threatening of higher risk of REP. REP is defined as a new enhancing tumor or >25% increase in enhancement before radiotherapy. Lim′s classification of initial glioblastoma location related to these NSC regions predicts invasive and multifocal tumor phenotype. Glioblastomas are classified preoperatively into four groups by the spatial relationship of the contrast-enhancing lesion with the SVZ and cortex. The aim of this retrospective single-institutional study is to evaluate the relations of this Lim classification on REP in unselected cohort of glioblastoma patients. MATERIAL AND METHODS Patients receiving radiotherapy between 2014–2017 were analyzed, 95 were evaluable. 47 patients (30.5%) were treated with the Stupp regimen. Lim1 classification (contact with cortex as well as SVZ) was presented in 74(48%) patients, Lim2 (contact with SVZ only) in 22(14.3%), Lim3 (contact with cortex only) in 50(32.5%) and Lim4 in 8(5.2%) patients. A total of 52% of patients developed REP. RESULTS Significantly better overall survival was with Stupp regimen (23.3 vs. 8.6 months, p<0.001) and without REP (18.5 vs. 10.2 months, p=0.001). There was no significant impact of time to start of radiotherapy. No significant relation between REP and Lim classification was observed. CONCLUSION The initial location is not predictive for REP. Patients experiencing REP have significantly worse overall survival and modification of their management represents an urgent unmet clinical need. Molecular and clinical biomarkers indicating an increased risk of REP are needed.Presented will also be an already published analysis of clinical factors associated with REP in glioblastoma and the effect of REP and treatment on survival outcomes. Newly, we will introduce the investigator-initiated prospective academic clinical trial (GlioMET) focused on optimization of glioblastoma radiotherapy by 11C-Methionine PET scan in patients with REP.

Purpose Adults who stutter (AWS) have increased risk of comorbid social anxiety about speaking in social contexts. AWS also report experiencing embarrassment in different social situations; however, research has rarely been conducted on embarrassment and its relationship to social anxiety in AWS. Method AWS ( N = 200) reported their level of embarrassment on four 10-point Likert items when speaking in four situational contexts: at home, to an individual important to them, in social groups, and at work. Participants were also assessed for sociodemographic, stuttering, and anxiety variables. Construct validity for the four embarrassment items was examined, the extent of embarrassment established in the four contexts as a function of age and sex, and the relationship of embarrassment to social anxiety evaluated. Results Evidence of acceptable construct validity and reliability is presented for the four embarrassment Likert items. Sixty-five percent of the sample experienced high levels of embarrassment when speaking in groups or at work, while 35.5% experienced high levels when speaking at home or to an individual important to them. Participants were significantly more embarrassed ( p < .01) when speaking at work or when socializing in groups. Embarrassment was lowest when speaking in the home. Younger females were significantly more embarrassed when speaking at work or when socializing in groups. Those with high embarrassment scores on all four items were more likely to have elevated social anxiety scores ( p < .001). Conclusion These preliminary results suggest that the assessment of situational embarrassment could be an important clinical measure that may help improve stuttering treatment outcomes that also target social anxiety.
