Cancer metastasis occurs through local invasion of circulating tumour cells (CTCs), intravasation, transportation to distant sites, and their extravasation followed by colonisation at secondary sites. Epithelial–mesenchymal transition (EMT) is a normal developmental phenomenon, but its aberrant activation confers tumour cells with enhanced cell motility, metastatic properties, resistant to therapies and cancer stem cell (CSC) phenotype in epithelium-derived carcinoma. Experimental studies from various research papers have been reviewed to determine the factors, which interlink cancer stemness and cellular plasticity with EMT. Although existence of CSCs has been linked with EMT, nevertheless, there are controversies with the involvement of type of tumour cells, including cells with E (epithelial) and M (mesenchymal) phenotype alone or hybrid E/M phenotype in different types of cancers. Studies on CTCs with hybrid E/M phenotypes during different stages of cancer metastasis reveal strong association with tumour -initiation potential, cellular plasticity and types of cancer cells. Cells with the hybrid E/M state are strictly controlled by phenotypic stability factors coupled to core EMT decision-making circuits, miR200/ZEB and miR-34/Snail. Understanding the regulatory functions of EMT program in cancer metastasis can help us to characterise the biomarkers of prognostic and therapeutic potential. These biomarkers when targeted may act as metastatic suppressors, inhibit cellular plasticity and stemness ability of tumour cells and can block metastatic growth.

A study focuses on providing information about the natural products of chromene, furochromenes, pyranochromenes, and benzochromene ring systems, along with the synthesis of various aromatized and partially reduced chromenes, benzo-, and naphtho-fused chromenes, thiochromenopyrans, and their applications in synthetic organic chemistry for the construction of numerous diverse compounds. It is demonstrated that the presence of nitro group at C-5 in XVIIa,b affects the chemical shifts of H-4 and H-6 protons, and they resonate downfield as compared to respective protons of XVIIc due to the presence of electron-withdrawing substituents. It has also been observed that various substituted 2H-chromenes isolated from the leaves of Orthosiphom aristatus have been used as traditional medicine for the treatment of hypertension and diabetes.

Atrophic rhinitis is a chronic nasal pathology characterised by the formation of thick dry crusts in a roomy nasal cavity, which has resulted from progressive atrophy of the nasal mucosa and underlying bone. The common symptoms may include foetor, ozaena, crusting/nasal obstruction, epistaxis, anosmia/cacosmia and secondary infection with maggot infestation. Its prevalence varies in different regions of the world and it is common in tropical countries. The condition is predominantly seen in young and middle-aged adults, especially females, with a racial preference amongst Asians, Hispanics and African-Americans. A wide variety of treatment modalities have been described in the literature, however the mainstay of treatment is conservative (for example, nasal irrigation and douches; nose drops (e.g. glucose-glycerine, liquid paraffin); antibiotics and antimicrobials; vasodilators and prostheses). Surgical treatment aims to decrease the size of the nasal cavities, promote regeneration of normal mucosa, increase lubrication of dry nasal mucosa and improve the vascularity of the nasal cavities. To assess the effectiveness of interventions for atrophic rhinitis. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the search was 28 March 2011. Randomised controlled trials (RCTs) studying any treatment or combination of treatments in patients with atrophic rhinitis. We excluded studies with follow-up of less than five months following treatment/intervention. Three review authors abstracted and assessed studies. We tabulated and then compared the responses of the review authors separately for the individual studies. No studies met the inclusion criteria for the review. We identified one RCT comparing oral rifampicin plus nasal wash versus nasal submucosal placentrex injection plus nasal wash versus a control group (nasal wash) but had to exclude this study due to inadequate length of follow-up. A further RCT comparing Young's operation with nasal lubrication for primary atropic rhinitis is underway. There is no evidence from randomised controlled trials concerning the long-term benefits or risks of different treatment modalities for atrophic rhinitis. Further high-quality research into this chronic disease, with a longer follow-up period, is therefore required to establish this conclusively.

The present study is the first attempt to develop an annual (August-July) precipitation series back to AD 1330 using a tree ring data network of Himalayan cedar (Cedrus deodara (Roxb.) G. Don) from the Lahaul-Spiti region in the western Himalaya, India. The rainfall reconstruction reveals high magnitude multidecadal droughts during the 14th and 15th centuries and thenceforth a gradual increase in precipitation. Increasingly wet conditions during the 20th century are consistent with other long-term precipitation reconstructions from high Asia and reflect a large-scale intensification of the hydrological cycle, coincident with what is anticipated due to global warming. Significant relationships between reconstructed precipitation and precipitation records from central southwest Asia, east of the Caspian Sea, ENSO (NINO4-SST) variability and summer monsoon rainfall over central northeast India underscore the utility of our data in synoptic climatology.

Tree-ring-width data of Himalayan cedar [Cedrus deodara (Roxb.) G. Don] from 11 homogeneous moisture stressed sites in the monsoon shadow zone of the western Himalaya were used to develop a mean chronology extending back to ad 1353. The chronology developed using Regional Curve Standardization method is the first from the Himalayan region of India showing centennial-scale variations. The calibration of ring-width chronology with instrumental precipitation data available from stations close to the tree ring sampling sites showed strong, direct relationship with March-April-May-June (MAMJ) precipitation. This strong relationship was used to supplement the instrumental precipitation data back to ad 1410. The precipitation reconstruction showed extended period of drought in fifteenth and sixteenth centuries. Increasingly pluvial conditions were recorded since eighteenth century, with the highest precipitation in the early part of the nineteenth century. The decreasing trend in reconstructed precipitation in the last decade of the twentieth century, consistent with the instrumental records, is associated with the decreasing trend in frequency of western disturbances. MAMJ precipitation over the monsoon shadow zone in the western Himalaya is directly associated with the North Atlantic Oscillation (NAO) and NINO3-SST index of El Nino-Southern Oscillation (ENSO), the leading modes of climate variability influencing climate over large parts of the Northern Hemisphere. However, the relationship between ENSO and MAMJ precipitation collapsed completely during 1930-1960. The breakdown in this relationship is associated with the warm phase of Atlantic Multidecadal Oscillation (AMO). A spectral analysis of reconstructed MAMJ precipitation indicates frequencies in the range of the variability associated with modes of NAO, ENSO and AMO. © 2010 Springer-Verlag.

The paucity of available instrumental climate records in cold and arid regions of the western Himalaya, India, hampers our understanding of the long-term variability of regional droughts, which seriously affect the agrarian economy of the region. Using ring width chronologies of Cedrus deodara and Pinus gerardiana together from a network of moisture-stressed sites, Palmer Drought Severity Index values for October-May back to 1310 A.D. were developed. The twentieth century features dominant decadal-scale pluvial phases (1981-1995, 1952-1968, and 1918-1934) as compared to the severe droughts in the early seventeenth century (1617-1640) as well as late fifteenth to early sixteenth (1491-1526) centuries. The drought anomalies are positively (negatively) associated with central Pacific (Indo-Pacific Warm Pool) sea surface temperature anomalies. However, non-stationarity in such relationships appears to be the major riddle in the predictability of long-term droughts much needed for the sustainable development of the ecologically sensitive region of the Himalayas.

Expert Opinion on Therapeutic Targets | Year: 2015

Introduction: Epithelial-to-mesenchymal transition (EMT) is a pathological phenomenon of cancer that confers tumor cells with increased cell motility, invasive and metastatic abilities with the acquisition of 'cancer stem-like cell' (CSC) phenotype. EMT endows tumor cells with intrinsic/acquired resistant phenotype at achievable doses of anticancer drugs and leads to tumor recurrence and progression. Besides the complex network of signaling pathways, microRNAs (miRNAs) are being evolved as a new player in the induction and regulation of EMT. Areas covered: In this review article, the author has searched the PubMed and Google Scholar electronic databases for original research and review articles to gather current information on the association of EMT-induced CSCs with therapeutic resistance, tumor growth and metastasis, which are believed to be regulated by certain miRNAs. Expert opinion: This review outlines not only the perspective on selective targeting of EMT-induced CSCs through altered expression of novel miRNAs and/or the use of conventional drugs that affect the levels of critical miRNAs but also the strategies on overcoming the drug resistance by interfering with EMT and modulating its associated pathways in CSCs that can be considered as potential therapeutic approaches toward eradicating the tumor recurrence and metastasis. © 2015 Informa UK, Ltd.

In the central and western part of India, the Neoproterozoic deposits are identified in the Vindhyan and Marwar Basins. The Vindhyan Basin consists of two sub-basins; one in the eastern part and the other in the western part. The basic problem with the Vindhyan Basin is the correlation of the eastern part with the western part, as the two areas show different stratigraphic successions and the outcrops in the eastern part are not traceable in the western part. In this paper, an attempt is made to suggest intrabasinal correlation within the Vindhyan Basin on the basis of stromatolites, carbon isotope data, microbial mats, fossils and lithology. The Marwar Supergroup is developed in the western Rajasthan and unconformably overlies the Malani Igneous Suite, which has previously been dated as 779-681 Ma. On the basis of the available fossil records, the Jodhpur Group has been assigned an Ediacaran age and the Precambrian-Cambrian boundary is suggested within the Bilara Group. As both the Maihar Sandstone of the eastern part of the Vindhyan Basin and the Jodhpur Sandstone of the Marwar Supergroup have been assigned an Ediacaran age, these have been correlated. © The Geological Society of London 2012.

The viscosity (η) of formamide (FA) with 2-methoxyethanol (2-ME) and 2-ethoxyethanol (2-EE) has been measured at 303.15, 308.15, 313.15, 318.15 and 323.15 K over the entire composition range. From the experimental viscosity data, viscosity deviations (Δη) of binary mixtures were evaluated and fitted to the Redlich-Kister equation. The Δη values are positive over the entire range of composition for (formamide + 2-methoxyethanol) and (formamide + 2-ethoxyethanol) systems. The Grunberg-Nissan (d 12), Tamura-Kurata (T 12) and Hind (H 12) interaction parameters have been calculated. Furthermore, Gibbs free energy of activation (ΔG*), enthalpy of activation (ΔH*), entropy of activation (ΔS*) and excess Gibbs free energy of activation (ΔG* E) of viscous flow have also been evaluated by using Eyring viscosity equation. The results are discussed in terms of molecular interactions due to physical, chemical and structural effects between the unlike molecules. It is observed that the strength of intermolecular interaction between FA and 2-alkoxyethanol molecules is in order: FA + 2-EE > FA + 2-ME. © 2012 Elsevier B.V. All rights reserved.

The ultrasonic velocity (u) and density (ρ) of binary mixtures of formamide (FA) with 2-methoxyethanol (2-ME) and 2-ethoxyethanol (2-EE) have been measured over the entire composition range at temperatures (303.15, 313.15, and 323.15) K. The experimental values of ultrasonic velocities and densities have been used to determine the adiabatic compressibility (β S), intermolecular free length (L f), molar sound velocity (R), molar compressibility (B), and specific acoustic impedance (Z). The excess values of ultrasonic velocity (u E), adiabatic compressibility (β S E), acoustic impedance (Z E), and molar volume (V m E) were also calculated. The observed variations of these parameters, with composition and temperature, are discussed in terms of the molecular interactions due to physical, chemical, and structural effects between the unlike molecules of the binary mixtures. Further, the infrared spectra of both the systems, (FA + 2-ME) and (FA + 2-EE), have also been recorded at room temperature and found to be useful for understanding the presence of extensive hydrogen bonding between oxygen atom of C=O group of formamide and hydrogen atoms of the H-O group of 2-alkoxyethanol molecules in these binary liquid mixtures. © 2012 Elsevier Ltd.
