IOT BASED REAL TIME TELE-HEALTHCARE SYSTEM

Tele-healthcare is need of the hour to bridge the vast healthcare gap in developing country like India. Being the second most populous country, quality healthcare facility is not easily accessible in the rural outskirts of India. In this research work the proposed system has acquired ECG, heart rate, SpO2 and body temperature data for better diagnosis and prognosis. The proposed system has been tested on the different patients belonging to different age groups and the result obtained on the health monitoring dashboard is found to be satisfactory. It also provides enhanced accessibility as multiple healthcare professionals can collaborate on the patient's data. This paper concludes with real time audio/ video connectivity, scope of interest of which is very effective and applicable in healthcare world.

Genetic diversity and population structure analysis of Asian and African aromatic rice (Oryza sativa L.) genotypes

Rice germplasms collected from different regions could be used as valuable resources for the future breeding programme. For the utilization of such collections, knowledge about the level and distribution of genetic diversity among these collections will facilitate the breeder. In this study, we report the phenotypic correlation, biochemical quality parameters and population genetic analysis of 35 rice accessions including 34 aromatic rice from different countries and a nonaromatic, Nagina 22, a well-known drought resistance variety. Further biochemical quality analysis, gel consistency test, molecular diversity analysis with 55 simple sequence repeat markers, population structure analysis and pair wise FST analysis were also conducted to assess the genetic diversity. The collected rice genotypes showed significant variability in different agronomic traits, i.e. spikelet per panicle, branches per panicle etc. Results obtained from the above tests demonstrated the importance of regional genetic studies for understanding the diversification of aromatic rice in Asian and African rice.

Problems associated with clinical trials of Ayurvedic medicines / Problemas associados com ensaios clínicos de medicamentos Ayurvédicos

Herbal drugs have been used since ancient times as medicines for the treatment of various diseases. Especially in countries like India many of herbal drugs and formulations are used in different practices of treatment like Ayurveda, Siddha and Unani. It is estimated that about 25 percent of all modern medicines are directly or indirectly derived from plants sources. The contribution of developing countries in global herbal business is very poor due to lack of quality control and standardization measures. There is lack of common standards and appropriate methods for evaluating Traditional Medicine to ensure the safety, efficacy and quality control. This indicates the importance and necessity to develop a standard operational procedure for the standardization of herbal drugs and formulations. Benchmarking the evaluation protocols including both quality control and quality assurance of herbal drugs would play a major role in providing highly reliable and effective herbals drugs and to attract international trade, thus generating revenue. The article highlights various problems being faced by developing countries and suggests a unique approach for the preparation of SOP/guidelines for the standardization of all herbal based formulations, also there is a need for systematic clinical trials of traditional plant based medicines to enhance global acceptance

Weill-Marchesani syndrome associated with retinitis pigmentosa.

Retinitis pigmentosa (RP) is associated with a wide variety of ocular and systemic disorders. The Weill-Marchesani syndrome is a multi-system disorder with microspherophakia as one of the common manifestations. A 14-year-old girl presented with short stature, short and stubby fingers, hypodontia and low-set ears. Slit-lamp examination revealed microspherophakia, with shallow anterior chambers with irido and phacodonesis. Ultrasonographic biomicroscopy confirmed the clinical findings and revealed hypoplastic ciliary body. Electroretinogram confirmed the diagnosis of RP. Though RP has been associated with ectopia lentis in earlier reports, this is, to the best of our knowledge, the first case report describing the association of RP and Weill-Marchesani syndrome.

Regulation of activity of the yeast TATA-binding protein through intra-molecular interactions.

Dimerization is proposed to be a regulatory mechanism for TATA-binding protein (TBP) activity both in vitro and in vivo. The reversible dimer-monomer transition of TBP is influenced by the buffer conditions in vitro. Using in vitro chemical cross-linking, we found yeast TBP (yTBP) to be largely monomeric in the presence of the divalent cation Mg2+, even at high salt concentrations. Apparent molecular mass of yTBP at high salt with Mg2+, run through a gel filtration column, was close to that of monomeric yTBP. Lowering the monovalent ionic concentration in the absence of Mg2+, resulted in dimerization of TBP. Effect of Mg2+ was seen at two different levels: at higher TBP concentrations, it suppressed the TBP dimerization and at lower TBP levels, it helped keep TBP monomers in active conformation (competent for binding TATA box), resulting in enhanced TBP-TATA complex formation in the presence of increasing Mg2+. At both the levels, activity of the full-length TBP in the presence of Mg2+ was like that reported for the truncated C-terminal domain of TBP from which the N-terminus is removed. Therefore for full-length TBP, intra-molecular interactions can regulate its activity via a similar mechanism.

The transcriptional activator GAL4-VP16 regulates the intra-molecular interactions of the TATA-binding protein.

Binding characteristics of yeast TATA-binding protein (yTBP) over five oligomers having different TATA variants and lacking a UASGAL, showed that TATA-binding protein (TBP)-TATA complex gets stabilized in the presence of the acidic activator GAL4-VP16. Activator also greatly suppressed the non-specific TBP-DNA complex formation. The effects were more pronounced over weaker TATA boxes. Activator also reduced the TBP dimer levels both in vitro and in vivo, suggesting the dimer may be a direct target of transcriptional activators. The transcriptional activator facilitated the dimer to monomer transition and activated monomers further to help TBP bind even the weaker TATA boxes stably. The overall stimulatory effect of the GAL4-VP16 on the TBP-TATA complex formation resembles the known effects of removal of the N-terminus of TBP on its activity, suggesting that the activator directly targets the N-terminus of TBP and facilitates its binding to the TATA box.

Cloning and sequencing of complete tau-crystallin cDNA from embryonic lens of Crocodylus palustris.

tau-Crystallin is a taxon-specific structural protein found in eye lenses. We present here the cloning and sequencing of complete tau-crystallin cDNA from the embryonic lens of Crocodylus palustris and establish it to be identical to the a-enolase gene from non-lenticular tissues. Quantitatively, the tau-crystallin was found to be the least abundant crystallin of the crocodilian embryonic lenses. Crocodile tau-crystallin cDNA was isolated by RT-PCR using primers designed from the only other reported sequence from duck and completed by 5'- and 3'-rapid amplification of cDNA ends (RACE) using crocodile gene specific primers designed in the study. The complete tau-crystallin cDNA of crocodile comprises 1305 bp long ORF and 92 and 409 bp long untranslated 5'- and 3'-ends respectively. Further, it was found to be identical to its putative counterpart enzyme a-enolase, from brain, heart and gonad, suggesting both to be the product of the same gene. The study thus provides the first report on cDNA sequence of tau-crystallin from a reptilian species and also re-confirms it to be an example of the phenomenon of gene sharing as was demonstrated earlier in the case of peking duck. Moreover, the gene lineage reconstruction analysis helps our understanding of the evolution of crocodilians and avian species.
