Gentrification through Green Regeneration? Analyzing the Interaction between Inner-City Green Space Development and Neighborhood Change in the Context of Regrowth: The Case of Lene-Voigt-Park in Leipzig, Eastern Germany

Green regeneration has become a common strategy for improving quality of life in disadvantaged neighborhoods in shrinking cities. The role and function of new green spaces may change, however, when cities experience new growth. Set against this context, this paper analyzes a case study, the Lene-Voigt-Park in Leipzig, which was established on a former brownfield site. Using a combination of methods which include an analysis of housing advertisements and interviews, the paper explores the changing role of the park in the context of urban regeneration after the city’s turn from shrinkage towards new growth. It discusses whether the concept of green gentrification may help to explain this role. As a result of our analysis, we argue that Lene-Voigt-Park has indeed operated as a trigger for structural, social, and symbolic upgrades in the growing city of Leipzig, but only in combination with real estate market developments, which are the main drivers of change. The concept of green gentrification does help to better understand the role of different factors—first and foremost that of green space. We also discovered some specifics of our case that may enrich the green gentrification debate. Leipzig serves as an example for a number of regrowing cities across Europe where green gentrification might represent a challenge.DFG, 414044773, Open Access Publizieren 2019 - 2020 / Technische Universität Berli

Illuminating the dark side-vitamin D status in different localities of Karachi

Abstract This study was conducted to determine the association between place of residence (grouped into neighbourhoods), and 25-hydroxy D (25[OH]D) levels of individuals of Karachi. Addresses of 4788 individuals tested for 25[OH]D at the clinical laboratory of the Aga Khan University (AKU), Karachi, from January 2007 to June 2008 were reviewed. The neighbourhoods were categorized into ten, based on locality attributes. A high overall prevalence (74%) of vitamin D deficiency (VDD) was observed. There was a significant difference (p-value \u3c 0.01) between mean log 25[OH]D levels amongst neighbourhoods grouped according to distinct housing structure attributes and localities. A high frequency of VDD in all the studied localities of an urban city warrant dietary vitamin D supplementation and food fortification

The Protective Effect of Radish (Raphanus sativus) Seeds Against the Oxidative Stress Induced by Sodium Nitrite in Male Rabbits (Oryctolagus cuniculus)

The aim of this study is to investigate the protective effect of Radish (Raphanus sativus) seed alcoholic extract 70% against oxidative stress induced by sodium nitrite NaNO2 Twenty five adult male rabbits were devided into five groups of (five rabbits in each group) and treated daily for 30 days. Group T1: intubated orally 20 mg/kg NaNO2, Group T2: intubated orally 20 mg/kg NaNO2 + 50 mg/kg of alcoholic extract from Raphanus sativus seeds, Group T3: intubated orally 20 mg/kg NaNO2 + 100 mg/kg of alcoholic extract from Raphanus sativus seeds, Group T4: intubated orally 20 mg/kg NaNO2 + 200 mg/kg of alcoholic extract from Raphanus sativus seed as well as Group C: control intubated orally distilled water. In comparison with normal rabbits there were significantly increase in the level of Methemoglobin (MetHb%) , lipid peroxidation indicator malondialdehyde (MDA), and significantly decrease in the level of glutathione (GSH) in the rabbits intubated NaNO2. In rabbits intubated NaNO2 + 50,100,200 mg/kg of alcoholic extract it was found there were significant decreased in the level of MetHb%, MDA, and increase in the level of GSH. In conclusion according to results obtained from this study approved that alcoholic extract of Raphanus sativus seeds in dose (50,100,200 mg/kg) have protective effect against oxidative stress induced by sodium nitrite in male rabbits

Model Reduction for Kinetic Models of Biological Systems

High dimensionality continues to be a challenge in computational systems biology. The kinetic models of many phenomena of interest are high-dimensional and complex, resulting in large computational effort in the simulation. Model order reduction (MOR) is a mathematical technique that is used to reduce the computational complexity of high-dimensional systems by approximation with lower dimensional systems, while retaining the important information and properties of the full order system. Proper orthogonal decomposition (POD) is a method based on Galerkin projection that can be used for reducing the model order. POD is considered an optimal linear approach since it obtains the minimum squared distance between the original model and its reduced representation. However, POD may represent a restriction for nonlinear systems. By applying the POD method for nonlinear systems, the complexity to solve the nonlinear term still remains that of the full order model. To overcome the complexity for nonlinear terms in the dynamical system, an approach called the discrete empirical interpolation method (DEIM) can be used. In this paper, we discuss model reduction by POD and DEIM to reduce the order of kinetic models of biological systems and illustrate the approaches on some examples. Additional computational costs for setting up the reduced order system pay off for large-scale systems. In general, a reduced model should not be expected to yield good approximations if different initial conditions are used from that used to produce the reduced order model. We used the POD method of a kinetic model with different initial conditions to compute the reduced model. This reduced order model is able to predict the full order model for a variety of different initial conditions.TU Berlin, Open-Access-Mittel – 2020EC/H2020/765374/EU/Reduced Order Modelling, Simulation and Optimization of Coupled systems/ROMSO

Retrospective study of patients with hyperphenylalaninemia: Experience from a tertiary care center in Pakistan

Objective: To assess the clinical and biochemical features as well as outcome of perphenylalaninemia patients.Methods: The descriptive retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised data from January 2013 to February 2017 of plasma amino acid analysed at the Biochemical Genetic Laboratory of patients with phenylalanine levels \u3e120 umol/L. Medical charts of patients registered with the Metabolic Clinics were reviewed, while outside referrals were contacted by telephone to collect data on a pre-structured questionnaire. Data was analysed using SPSS 21. Results: Of the 18 patients, 13(72%) were males. Overall median age was 606 days (interquartile range: 761) and median phenylalanine levels were 1280 (interquartile range: 935) umol/L. Phenylalanine hydroxylase deficiency was present in 5(28%) patients while 3(16.6%) had defects in the metabolism or regeneration of tetrahydrobiopterin. The most common clinical features was intellectual deficit and seizures 14(78%) each, followed by lighter hair colour 10(55.5%) and hypotonia 11(61%). High treatment cost was the leading reason for cessation of therapy in 7(39%) followed by refusal by patient\u27s family 5(28%).Conclusion: Most hyperphenylalaninemia cases were diagnosed late when intellectual disability had already developed
