In vitro studies on effects of plant growth regulators on callus and suspension culture biomass yield from Gymnema sylvestre R.Br

Callus cultures were initiated from nodal segments and leaf explants of Gymnema sylvestre on Murashige and Skoog (1962) medium containing basic salts and 30 g/l sucrose supplemented with different concentrations (0.10, 0.25, 0.5, 1.0, 2.0 and 5.0 mg/l) of 2,4-dichlorophenoxy acetic acid (2,4-D), -naphthalene acetic acid (NAA), indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), kinetin (KN) and 6-benzyladenine (BA). Callus induction was observed in 0.5 mg/l of 2, 4-D supplemented medium for both explants. At the initial stage, some parts of explants enlarged and gave raise to pale yellowish calli after 2-3 weeks of incubation. The harvested cell biomass was subjected to extraction of active principles. In this study, cell biomass extracts were compared with extracts from leaves of naturally growing gymnema plants. HPLC analysis of these extracts showed that the main components of the active principles namely gymnemic acids and gymnemagenin were present in sufficiently large amounts in the cultured undifferentiated cell

A 3 year retrospective study of pregnancies complicated with placenta previa in a tertiary care centre

Background: Placenta previa describes when a placenta is implanted partially or completely over the internal OS. About one third of the ante partum haemorrhage belongs to placenta previa. The incidence is increased beyond the age of 35 years, with high birth order pregnancies, prior caesarean deliveries and in multiple pregnancy. The aim of the study was to determine maternal and fetal outcome in pregnancies complicated with placenta previa.Methods: A 3 year retrospective study done in OBG department of A. J. Institute of Medical Sciences, Mangalore from January 2017- January 2020. All pregnant women who are diagnosed with placenta previa during regular antenatal care (ANC) follow up, at or after admission and during caesarean delivery are included in the study. Data were collected from the hospital records.Results: During the study period, there were 34 pregnant women with placenta previa. Maximum were in the age group of 31-35 years of age and 8.82 percentage were in the age group more than 35 years. Out of the study subjects,76.5 percentage were multigravidas and 50 percentage were giving history of prior one caesarean section. 29.4 percentage of study subjects had true placenta previa and 85.2 percentage underwent elective caesarean section. There were significantly higher number of babies required neonatal intensive care unit (NICU) admissions.Conclusions: An increase in the incidence of women with advanced maternal age, multiparity, prior caesarean deliveries contributes to a rise in the number of pregnancies complicated with placenta previa

Internet of Things: Usage of LiFi and Need for Flow Control Protocol

The Internet of Things (IoT) is the future of Internet. It is the network of physical objects accessed through Internet. The objects have embedded sensors that will capture potentially enormous amounts of data, A processing system inside the object processes the captured data and these processed data are to be transmitted as quickly as possible. Thus there is a requirement for high bandwidth network and appropriate data transfer protocols

Sphinx 4 Speech Recognition in ATC

Speech Recognition plays a very important role in day to day life. Speech Recognition is widely used and addicted by this world as it allows users to communicate with computers by recognizing their spoken language. Communication with Speech Recognition made our lives easy. There are many types of open source Speech Recognition Engine. Different types of application are built using Speech Recognition Engine. An Application is built for Air Traffic Controller. A new Software library with good grammar is proposed according to Air Traffic Controller commands. This Software library is used to build successful working application

La Vida e historia del rey Apolonio [¿Zaragoza, Juan Hurus, 1488?] y su trayectoria genérica*

En el artículo se analiza la diversa trayectoria genérica de la Vida e historia del rey Apolonio [¿Zaragoza, Juan Hurus, 1488?] desde una triple perspectiva. Por su origen, remonta a la Historia Apollonii regis Tyri, narración de origen clásico próxima a las novelas griegas. Su recepción hispánica se aleja de su género de creación, pues el texto es traducción de un capítulo de las Gesta romanorum, y se presentaría, impreso junto a los Siete sabios de Roma, como una historia ejemplar. Por último, la crítica moderna ha optado por insertarlo en la serie de los «romances de materia clásica» y en el género editorial de las «historias caballerescas breves»

Differentially localized survivin and STAT3 as markers of gastric cancer progression: Association with Helicobacter pylori

BackgroundLocalization and differential expression of STAT3 and survivin in cancer cells are often related to distinct cellular functions. The involvement of survivin and STAT3 in gastric cancer has been reported in separate studies but without clear understanding of their kinetics in cancer progression.MethodsWe examined intracellular distribution of STAT3 and survivin in gastric adenocarcinoma and compared it with normal and precancer tissues using immunoblotting and immunohistochemistry.ResultsAnalysis of a total of 156 gastric samples comprising 61 histologically normal, 30 precancerous tissues (comprising intestinal metaplasia and dysplasia), and 65 adenocarcinomas, collected as endoscopic biopsies from treatment naïve study participants, revealed a significant (P < .001) increase in overall protein levels. Survivin expression was detectable in both cytoplasmic (90.8%) and nuclear (87.7%) compartments in gastric adenocarcinomas lesions. Precancerous dysplastic gastric lesions exhibited a moderate survivin expression (56.7%) localized in cytoplasmic compartment. Similarly, STAT3 and pSTAT3 expression was detected at high level in gastric cancer lesions. The levels of compartmentalized expression of survivin and STAT3/pSTAT3 correlated in precancerous and adenocarcinoma lesions. Although overexpression of these proteins was found associated with the tobacco use and alcohol consumption, their expression invariably and strongly correlated with concurrent Helicobacter pylori infection. Receiver operating characteristic analysis of nuclear survivin, STAT3, and pSTAT3 in different study groups showed acceptable positive and negative predictive values with area under the curve above 0.8 (P < .001).ConclusionOverall, our results suggest that overall increase in survivin and STAT3 and their subcellular localization are key determinants of gastric cancer progression, which can be collectively used as potential disease biomarkers and therapeutic targets for gastric cancer.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/1/cnr21004-Supplementary_Methods_20180313.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/2/cnr21004-sup-0001-F1.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/3/cnr21004_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/4/cnr21004.pd
