Pattern self-medication use of analgesics in Pune, Maharashtra, India

Background: Objective of current study was to find out self-medication pattern and to study awareness of ADRs to analgesics self-medication.Methods: II MBBS students collected the information of names of analgesics self-medication, dose, frequency of administration, health related problem for use of self-medication, source of information for the use of self-medication and information about ADRs. Students also educated the population about ADRs to analgesics with the help of ADR checklist.Results: Paracetamol was most commonly taken as self-medication and 39% persons reported ADRs with paracetamol.  Ibuprofen, diclofenac, paracetamol and aspirin were taken less than WHO DDD for joint pain. 79% study population was ignorant about ADRs to analgesics. Headache (37%) was common health related problem for self-medication of analgesics.   Conclusion: Information about problems with repeated use of analgesics like liver damage, analgesic nephropathy, gastric ulceration/bleeding should be provided by pharmacists either orally or with the help of leaflets or display board. Headache is common health related problem for the use of analgesics as self-medication. Pharmacists should take help of assistance tool to diagnosis headache like screener for migraine and guidelines for chronic headache for timely visit of self-medicating person to physician.

Characterization of a Drosophila Alzheimer's Disease Model: Pharmacological Rescue of Cognitive Defects

Transgenic models of Alzheimer's disease (AD) have made significant contributions to our understanding of AD pathogenesis, and are useful tools in the development of potential therapeutics. The fruit fly, Drosophila melanogaster, provides a genetically tractable, powerful system to study the biochemical, genetic, environmental, and behavioral aspects of complex human diseases, including AD. In an effort to model AD, we over-expressed human APP and BACE genes in the Drosophila central nervous system. Biochemical, neuroanatomical, and behavioral analyses indicate that these flies exhibit aspects of clinical AD neuropathology and symptomology. These include the generation of Aβ40 and Aβ42, the presence of amyloid aggregates, dramatic neuroanatomical changes, defects in motor reflex behavior, and defects in memory. In addition, these flies exhibit external morphological abnormalities. Treatment with a γ-secretase inhibitor suppressed these phenotypes. Further, all of these phenotypes are present within the first few days of adult fly life. Taken together these data demonstrate that this transgenic AD model can serve as a powerful tool for the identification of AD therapeutic interventions

Management Approaches

MM - P&DMThe purpose of this study is to analyse approaches of managers in development co-operation in facing challenges of complexity, change and the unknown. The research has been conducted as an explanatory case study on four German managers working in public development co-operation in Southern Africa. The analytical framework has been derived from management applications of the sciences of complexity. One of the main findings of the research is that on the surface development co-operation and development managers today have accepted development as being complex, non-linear and dynamic. However, the approaches used by managers rely on technical and strategic skills to respond to the pressure of accountability and achieving visible results. To achieve success and impact-orientation, governments, donor agencies and the managers involved have to accept development objectives as a political and personal challenge rather than a mere technical tas

Serotonin in pre-implantation mouse embryos is localized to the mitochondria and can modulate mitochondrial potential

Serotonin is reported to be present in early embryos of many species and plays an important role in early patterning. Since it is a fluorophore, it can be directly visualized using fluorescence microscopy. Here, we use three-photon microscopy to image serotonin in live pre-implantation mouse embryos. We find that it is present as puncta averaging 1.3 square microns and in concentrations as high as 442 mM. The observed serotonin puncta were found to co-localize with mitochondria. Live embryos pre-incubated with serotonin showed a higher mitochondrial potential, indicating that it can modulate mitochondrial potential. Pre-implantation mouse embryos were also examined at various developmental stages for the presence of transcripts of the peripheral and neuronal forms of tryptophan hydroxylase (Tph1 and Tph2 respectively) and the classical serotonin transporter (Slc6a4). Transcripts of Tph2 were seen in oocytes and in two-cell stages, whereas transcripts of Tph1 were not detected at any stage. Transcripts of the transporter, Slc6a4, were present in all pre-implantation stages investigated. These results suggest that serotonin in embryos can arise from a combination of synthesis and uptake from the surrounding milieu

Oncostatin-M Differentially Regulates Mesenchymal and Proneural Signature Genes in Gliomas via STAT3 Signaling

Glioblastoma (GBM), the most malignant of the brain tumors is classified on the basis of molecular signature genes using TCGA data into four subtypes- classical, mesenchymal, proneural and neural. The mesenchymal phenotype is associated with greater aggressiveness and low survival in contrast to GBMs enriched with proneural genes. The proinflammatory cytokines secreted in the microenvironment of gliomas play a key role in tumor progression. The study focused on the role of Oncostatin-M (OSM), an IL-6 family cytokine in inducing mesenchymal properties in GBM. Analysis of TCGA and REMBRANDT data revealed that expression of OSMR but not IL-6R or LIFR is upregulated in GBM and has negative correlation with survival. Amongst the GBM subtypes, OSMR level was in the order of mesenchymal > classical > neural > proneural. TCGA data and RT-PCR analysis in primary cultures of low and high grade gliomas showed a positive correlation between OSMR and mesenchymal signature genes-YKL40/CHI3L1, fibronectin and vimentin and a negative correlation with proneural signature genes-DLL3, Olig2 and BCAN. OSM enhanced transcript and protein level of fibronectin and YKL-40 and reduced the expression of Olig2 and DLL3 in GBM cells. OSM-regulated mesenchymal phenotype was associated with enhanced MMP-9 activity, increased cell migration and invasion. Importantly, OSM induced mesenchymal markers and reduced proneural genes even in primary cultures of grade-III glioma cells. We conclude that OSM-mediated signaling contributes to aggressive nature associated with mesenchymal features via STAT3 signaling in glioma cells. The data suggest that OSMR can be explored as potential target for therapeutic intervention
