SUCCESSIVE SOLVENT EXTRACTION AND HPTLC OF STEM BARK OF ASOKA - SARACA ASOCA (ROXB.) DE WILDE

Asoka – Saraca asoca (Roxb.) de Wilde, is a medium sized evergreen tree growing in tropical regions. It has been used for various medicinal purposes from the time immemorial. Ample citations about its usage can be elicited from Veda’s, Puranas and Samhitas. Owing to extensive use, lack of cultivation and irrational collection practices it became an endangered drug. It’s one among the five endangered plants listed by NMPB. This scarcity of drug in the market eventually led to adulteration. It is one of the severely adulterated drug next to Bala – Sida species. Various pharmacognostical and phytochemical techniques are evolved from time to time to check the adulteration. Due to the sophisticated methodologies used by medicinal plant dealers, these methods fail to check adulteration. Pharmacognostical analysis of sample drug and its powder microscopy serves as an effective method to check adulteration. But it won’t serve fruitful when the drug gets adulterated with exhausted samples. In such cases, effective marker compounds of the drug need to be analysed. This can be achieved by analysing successive solvent extractives of test drug and by HPTLC analysis. Here an attempt has been done to analyse the successive solvent extraction and HPTLC of stem bark of Asoka – Saraca asoca (Roxb.) de Wilde. as an effective methodology to ensure the purity. The successive solvent extraction revealed 1.78%, 0.4%, 13.63% & 27.69% of extractives respectively in petroleum ether, cyclohexane, acetone and methyl alcohol. The qualitative analysis also showed significance difference in the steroids, alkaloids, phenols and flavonoids in each solvent. The results are promising and suggestive of considering these experiments as an effective method to ensure the quality and purity of drug sample

Effect of Ayurvedic Treatment Modalities on Recurrent Pregnancy Loss

Recurrent pregnancy Loss is defined as the sequence of 2 or more spontaneous abortions as documented by either sonography or on histopathology before 20 weeks. It is a relatively common event, occurring in 15%-25% of pregnancies, and increasing in prevalence with maternal age. The causes of recurrent abortion are complex & obscure. More than one factor may operate in a case. Identification and treatment of problems significantly increases the successful outcome in most cases. Recurrent pregnancy loss can be correlated with Puthraghni Yonivyapath and Garbhasravivandhya explained in Ayurvedic classics. Puthraghni is a clinical entity characterised by repeated pregnancy loss due to excessive intake of Rooksha Ahara and Vihara which results in repeated pregnancy losses. Ayurveda advises to do Shodhana Karma or purificatory therapies ending with Uttara Vasthi in recurrent losses. The study design was Prospective single arm interventional study conducted in the OPD and IPD of Govt. Ayurveda college hospital for Women and Children, Poojapura, Thiruvananthapuram with the study population of females of age group 20-38, diagnosed with RPL. IP management was done for 1 month followed by internal administration of Phala Sarpis as Vicharana Snehapana 10ml twice daily morning and evening ½ hour before food and Vilwadi Gulika 1 tab twice daily after food was also given for 2 months. After 15 months after the follow up period, Statistical analysis was done and Percentage of live births was assessed. Even though percentage of live births is 42.3, the success rate can be considered as 46.15% as the 1 patient to be delivered has completed 34 weeks of gestation and successfully continuing the pregnancy

P Deepa Shenoy and Venugopal KR,“PTMIB: Profiling Top Most Influential Blogger using Content Based Data Mining Approach,”

Users of Online Social Network (OSN) communicate with each other, exchange information and spread rapidly influencing others in the network for taking various decisions. Blog sites allow their users to create and publish thoughts on various topics of their interest in the form of blogs/blog documents, catching the attention and letting readers to perform various activities on them. Based on the content of the blog documents posted by the user, they become popular. In this work, a novel method to profile Top Most Influential Blogger (TMIB) is proposed based on content analysis. Content of blog documents of bloggers under consideration in the blog network are compared and analyzed. Term Frequency and Inverse Document Frequency (TF-IDF) of blog documents under consideration are obtained and their Cosine Similarity score is computed. Synonyms are substituted against those unmatched keywords if the Cosine Similarity score so computed is below the threshold and an improved Cosine Similarity score of those documents under consideration is obtained. Computing the Influence Score after Synonym substitution (ISaS) of those bloggers under conflict, the top most influential blogger is profiled. The simulation results demonstrate that the proposed Profiling Top Most Influential Blogger using Synonym Substitution (PTMIBSS) algorithm is adequately accurate in determining the top most influential blogger at any instant of time considered

IR, Raman and SERS spectra of 2-(methoxycarbonylmethylsulfanyl)-3,5-dinitrobenzene carboxylic acid

2-(Methoxycarbonylmethylsulfanyl)-3,5-dinitrobenzenecarboxylic acid was prepared by nucleophilic substitution. FT-IR and FT-Raman spectra of 2-(methoxycarbonylmethylsulfanyl)-3,5-dinitrobenzenecarboxylic acid were recorded and analyzed. Surface enhanced Raman scattering (SERS) spectrum was recorded on a silver colloid. The vibrational wavenumbers were computed by density functional theoretical (DFT) computations at the B3LYP/6-31G* level and they were found to be in good agreement with the experimental values. Significant metal-molecule interaction has been substantiated by the appearance of intense Ag-O mode in the SERS spectrum and this is indicative of the nearness of nitro and carbonyl group to the silver surface. SERS studies suggest a tilted orientation of the molecule at the metal surface

Genetic structure of Plasmodium falciparum field isolates in eastern and north-eastern India

<p>Abstract</p> <p>Background</p> <p>Molecular techniques have facilitated the studies on genetic diversity of <it>Plasmodium </it>species particularly from field isolates collected directly from patients. The <it>msp-1 </it>and <it>msp-2 </it>are highly polymorphic markers and the large allelic polymorphism has been reported in the block 2 of the <it>msp-1 </it>gene and the central repetitive domain (block3) of the <it>msp-2 </it>gene. Families differing in nucleotide sequences and in number of repetitive sequences (length variation) were used for genotyping purposes. As limited reports are available on the genetic diversity existing among <it>Plasmodium falciparum </it>population of India, this report evaluates the extent of genetic diversity in the field isolates of <it>P. falciparum </it>in eastern and north-eastern regions of India.</p> <p>Methods</p> <p>A study was designed to assess the diversity of <it>msp-1 </it>and <it>msp-2 </it>among the field isolates from India using allele specific nested PCR assays and sequence analysis. Field isolates were collected from five sites distributed in three states namely, Assam, West Bengal and Orissa.</p> <p>Results</p> <p><it>P. falciparum </it>isolates of the study sites are highly diverse in respect of length as well as sequence motifs with prevalence of all the reported allelic families of <it>msp-1 </it>and <it>msp-2</it>. Prevalence of identical allelic composition as well as high level of sequence identity of alleles suggest a considerable amount of gene flow between the <it>P. falciparum </it>populations of different states. A comparatively higher proportion of multiclonal isolates as well as multiplicity of infection (MOI) was observed among isolates of highly malarious districts Karbi Anglong (Assam) and Sundergarh (Orissa). In all the five sites, R033 family of <it>msp-1 </it>was observed to be monomorphic with an allele size of 150/160 bp. The observed 80–90% sequence identity of Indian isolates with data of other regions suggests that Indian <it>P. falciparum </it>population is a mixture of different strains.</p> <p>Conclusion</p> <p>The present study shows that the field isolates of eastern and north-eastern regions of India are highly diverse in respect of <it>msp-1 </it>(block 2) and <it>msp-2 </it>(central repeat region, block 3). As expected Indian isolates present a picture of diversity closer to southeast Asia, Papua New Guinea and Latin American countries, regions with low to meso-endemicity of malaria in comparison to African regions of hyper- to holo-endemicity.</p

Countdown to 2030 : tracking progress towards universal coverage for reproductive, maternal, newborn, and child health

Building upon the successes of Countdown to 2015, Countdown to 2030 aims to support the monitoring and measurement of women's, children's, and adolescents' health in the 81 countries that account for 95% of maternal and 90% of all child deaths worldwide. To achieve the Sustainable Development Goals by 2030, the rate of decline in prevalence of maternal and child mortality, stillbirths, and stunting among children younger than 5 years of age needs to accelerate considerably compared with progress since 2000. Such accelerations are only possible with a rapid scale-up of effective interventions to all population groups within countries (particularly in countries with the highest mortality and in those affected by conflict), supported by improvements in underlying socioeconomic conditions, including women's empowerment. Three main conclusions emerge from our analysis of intervention coverage, equity, and drivers of reproductive, maternal, newborn, and child health (RMNCH) in the 81 Countdown countries. First, even though strong progress was made in the coverage of many essential RMNCH interventions during the past decade, many countries are still a long way from universal coverage for most essential interventions. Furthermore, a growing body of evidence suggests that available services in many countries are of poor quality, limiting the potential effect on RMNCH outcomes. Second, within-country inequalities in intervention coverage are reducing in most countries (and are now almost non-existent in a few countries), but the pace is too slow. Third, health-sector (eg, weak country health systems) and non-health-sector drivers (eg, conflict settings) are major impediments to delivering high-quality services to all populations. Although more data for RMNCH interventions are available now, major data gaps still preclude the use of evidence to drive decision making and accountability. Countdown to 2030 is investing in improvements in measurement in several areas, such as quality of care and effective coverage, nutrition programmes, adolescent health, early childhood development, and evidence for conflict settings, and is prioritising its regional networks to enhance local analytic capacity and evidence for RMNCH

The impact of immediate breast reconstruction on the time to delivery of adjuvant therapy: the iBRA-2 study

Background: Immediate breast reconstruction (IBR) is routinely offered to improve quality-of-life for women requiring mastectomy, but there are concerns that more complex surgery may delay adjuvant oncological treatments and compromise long-term outcomes. High-quality evidence is lacking. The iBRA-2 study aimed to investigate the impact of IBR on time to adjuvant therapy. Methods: Consecutive women undergoing mastectomy ± IBR for breast cancer July–December, 2016 were included. Patient demographics, operative, oncological and complication data were collected. Time from last definitive cancer surgery to first adjuvant treatment for patients undergoing mastectomy ± IBR were compared and risk factors associated with delays explored. Results: A total of 2540 patients were recruited from 76 centres; 1008 (39.7%) underwent IBR (implant-only [n = 675, 26.6%]; pedicled flaps [n = 105,4.1%] and free-flaps [n = 228, 8.9%]). Complications requiring re-admission or re-operation were significantly more common in patients undergoing IBR than those receiving mastectomy. Adjuvant chemotherapy or radiotherapy was required by 1235 (48.6%) patients. No clinically significant differences were seen in time to adjuvant therapy between patient groups but major complications irrespective of surgery received were significantly associated with treatment delays. Conclusions: IBR does not result in clinically significant delays to adjuvant therapy, but post-operative complications are associated with treatment delays. Strategies to minimise complications, including careful patient selection, are required to improve outcomes for patients

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK ‘Alert Level 4’ phase of the B-MaP-C study

Abstract: Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown
