We suggest that these ARG transcription factors and epigenetic marks may represent important targets for future therapeutic intervention strategies in various neurodegenerative disorders including PD.The purpose of the study was to examine whether the underlying mechanism of the alteration of cognitive ability and synaptic plasticity induced by the housing environment is associated with the balance of excitatory/inhibitory synaptic density. Enriched environment (EE) and social isolation (SI) are two different housing environment, and one is to give multiple sensory environments, the other is to give monotonous and lonely environment. Male 4-week-old C57 mice were divided into three groups CON, EE and SI. They were housed in the different cage until 3 months of age. Morris water maze and novel object recognition were performed. Long term potentiation (LTP), depotentiation (DEP) and local field potentials were recorded in the hippocampal perforant pathway and dentate gyrus (DG) region. read more The data showed that EE enhanced the ability of spatial learning, reversal learning and memory as well as LTP/DEP in the hippocampal DG region. Meanwhile, SI reduced those abilities and the level of LTP/DEP. Moreover, there were higher couplings of both phase-amplitude and phase-phase in the EE group, and lower couplings of them in the SI group compared to that in the CON group. Western blot and immunofluorescence analysis showed that EE significantly enhanced the level of PSD-95, NR2B and DCX; however, SI reduced them but increased GABAARα1 and decreased DCX levels. The data suggests that the cognitive functions, synaptic plasticity, neurogenesis and neuronal oscillatory patterns were significantly impacted by housing environment via possibly changing the balance of excitatory and inhibitory synaptic density.Injection therapy is a frequently used method for the treatment of subacute and chronic low back pain (LBP) despite scant evidence for its effectiveness. To date there are relatively few studies comparing this method with other treatments. Moreover, there are many possible side effects associated with injection therapies, some of which are potentially life threatening. We present the case of a 59-year-old woman admitted to the emergency department with confluent abscess formations of autochthonous back muscles and staphylococcal sepsis caused by injection therapy performed by a general practitioner for LBP. The findings of this case report emphasize a careful selection of patients for this type of treatment and a multidisciplinary approach to treatment of LBP.

Computational models of cardiovascular structures rely on their accurate mechanical characterization. A validated method able to infer the material properties of patient-specific large vessels is currently lacking. The aim of the present study is to present a technique starting from the flow-area (QA) method to retrieve basic material properties from magnetic resonance (MR) imaging.

The proposed method was developed and tested, first, in silico and then in vitro. In silico, fluid-structure interaction (FSI) simulations of flow within a deformable pipe were run with varying elastic modules (E) between 0.5 and 32 MPa. The proposed QA-based formulation was assessed and modified based on the FSI results to retrieve E values. In vitro, a compliant phantom connected to a mock circulatory system was tested within MR scanning. Images of the phantom were acquired and post-processed according to the modified formulation to infer E of the phantom. Results of in vitro imaging assessment were verified against standard tensile test.

In silico results from FSI simulations were used to derive the correction factor to the original formulation based on the geometrical and material characteristics. In vitro, the modified QA-based equation estimated an average E = 0.51 MPa, 2% different from the E derived from tensile tests (i.e. E = 0.50 MPa).

This study presented promising results of an indirect and non-invasive method to establish elastic properties from solely MR images data, suggesting a potential image-based mechanical characterization of large blood vessels.

However, although the social pressure is high to increase the number of BCAs in use within the EU, the European plant protection products (PPP) regulation (EC) N° 1107/2009 does not define clearly what BCAs are. Therefore, problems and drawbacks are observed throughout the whole authorisation process. Consequently, this situation impedes drastically the rapid implementation of botanical BCAs and their subsequent use in the field. Previous studies described in detail the fate of BCAs and the current administrative process that leads to their approval. Drawbacks are described for GMOs but surprisingly scarcely for pesticides. Therefore, the present study pinpoints the drawbacks of the approval process of botanical BCAs. To achieve this goal, a comparative study of 5 substances (4 of plant origin and 1 chemical) was performed. This study clearly reveals the present weaknesses and loopholes in the European PPP regulation process. The results of the present study may be useful to initiate and promote a major change in the evaluation and the regulation process of BCAs. This should allow designing a novel and innovative framework enabling the development of future plant protection products according to the sustainable use of pesticides, described in the corresponding (EC) Directive N° 128/2009 (SUD). This work targets farmers, policy makers, NGOs and scientists interested in issues related to this topic.Urban Heat Island (UHI) is related to the theory of higher atmosphere and surface temperature taking place in the city area as compared to the nearby rural areas. The study results explain the advantages of green spaces in urban areas. Landsat TM/OLI concept of 1998 and 2017 years was attained from USGS for this work. To find out the land-use and land cover pattern supervised classification, the maximum prospect process is adopted. A total of four classes were mapped for the study area which includes built-up, barren land, vegetation, and water bodies. Effective sensor brightness temperature has been acquired from spectral radiance by using Plank's reverse function. On the basis of surface emissivity, Normalize Difference Vegetation Index (NDVI) classes are used to find out the ultimate temperature of the land surface (LST). The maximum temperature was recorded in the built-up area and barren land of the city and minimum temperatures were noted in areas with a greater cover of vegetation. The presence of UHI temperature is obvious from the land surface temperature views.
