Effects of Inorganic Mercury on Osteoclasts and Osteoblasts of the Goldfish Scales In Vitro

Abstract: Heavy metals such as mercury, cadmium and copper are known to be extremely toxic to organisms. Mercury has been recognized as an environmental contaminant since the Minamata disaster in the late 1950s. Minamata disease which was caused by the consumption of marine fishes severely polluted with mercury from local industrial discharge due to this Minamata disaster (Takeuchi et al., 1978; Takeuchi, 1982). This extremely adverse situation occurred because of mercury, a highly toxic compound, was severely bio–accumulated (in case of long– finned eels: approx. 1,000,000 times higher than environmental water) by fish (Redmayne et al., 2000). The effect of mercury on the central nervous system has widely studied and revealed that mercury is a neuro– toxic material, and its poisoning effect is characterized by the damage in discrete portions of the brain, such as the visual cortex and the granule layer of the cerebellum (Castoldi et al., 2001). As bio–accumulation of mercury in bone is lower than that in neural tissues (Boyer et al., 1978; Doyle, 1979; Berglund et al., 2000), much attention has not been given to bone in this area of research. Recently, Lake et al. (2006) reported that the correEffects of Inorganic Mercury on Osteoclasts and Osteoblasts of the Goldfish Scales In Vitro

Evolution of expansion-free spherically symmetric self-gravitating non-dissipative fluids and some analytical solutions

Abstract: We consider the distribution of spherically symmetric self-gravitating non-dissipative (but anisotropic) fluids under the expansion-free condition which requires the existence of vacuum cavity within the fluid distribution. The Darmois junction condition is investigated for matching the spherically symmetric metric to an internal vacuum cavity (Minkowski space-time). We have studied some analytical models, total of three family of solutions out of which two satisfy the junction conditions over both the hypersurfaces. The models are investigated under some known dynamical assumptions which further provide analytical solution in each family.

UN SDGs and Context of Holy-Heritage Cities in India: A Study of Ayodhya and Varanasi

Abstract: Following the UN SDGs (Sustainable Development Goals) Target 11.4, focussing on ‘Transforming our World: The 2030 Agenda for Sustainable Development’, cultural heritage and urban sustainability are now considered inseparable part of holistic development. Religion had played an important role for controlling power in Indian monarchy in the ancient past, and in contemporary India too it played a role in the formation of religious landscape and corporate identity of religious heritage, through commonly using processions, pilgrimage, religious assemblies, religious fairs (melā) and sacred places. Newly introduced concepts of pilgrimage tourism will help to revitalise these sacred cities. Situated in the Ganga river basin, Ayodhya and Banaras both have been primarily ancient tīrthas (riverfront sacredscapes) and salvific cities that record settlement continuity since at least ca 800BCE. Under the umbrella of holistic development, Government of India is promoting inclusive heritage sustainable development of heritage sites (cities), through active participation of stakeholders in the purview of SDGs and future development.

Multiwavelength Variability of the Blazars Mrk 421 and 3C 454.3 in the High-State

Abstract: We report the results of photometric observations of the blazars Mrk 421 and 3C 454.3 designed to search for intraday variability (IDV) and short-term variability (STV). Optical photometric observations were spread over eighteen nights for Mrk 421 and seven nights for 3C 454.3 during our observing run in 2009-2010 at the 1.04 m telescope at ARIES, India. Genuine IDV is found for the source 3C 454.3 but not for Mrk 421. Genuine STV is found for both sources. Mrk 421 was revealed by the MAXI X-ray detector on the International Space Station to be in an exceptionally high flux state in 2010 January - February. We performed a correlation between the X-ray and optical bands to search for time delays and found a weak correlation with higher frequencies leading the lower frequencies by about ten days. The blazar 3C 454.3 was found to be in high flux state in November-December 2009. We performed correlations in optical observations made at three telescopes, along with X-ray data from the MAXI satellite and public release gamma-ray data from the Fermi space telescope. We found strong correlations between the gamma-ray and optical bands at a time lag of about four days but the X-ray flux is not correlated with either. We briefly discuss the possible reasons for the time delays between these bands within the framework of existing models for X-ray and gamma-ray emission mechanisms.

Zinc(II) 5-(2′-hydroxyphenyl)-3-(4-X-phenyl)pyrazolinates and their adducts with N and P donor ligands: synthesis, spectral, biological, and anti-inflammatory investigations

Abstract: Synthesis, spectral, biological, and anti-inflammatory investigations of a series of complexes of zinc(II) with 5-(2′-hydroxyphenyl)-3-(4-X-phenyl)pyrazolines of the type (C15H12N2OX)2Zn (where X =–H,–Cl,–CH3,–OCH3) are presented. The complexes were synthesized by reaction of anhydrous zinc(II) chloride with sodium salts of pyrazoline in 1 : 2 molar ratio. Adducts with N and P donor ligands (2,2′-bipyridine, 1,10-phenanthroline and triphenylphosphine) were prepared in 1 : 1 molar ratio. The complexes were characterized by elemental analyses, molecular weight, conductivity, IR, electronic, 1H, 13C, 31P NMR, and FAB mass spectral studies. All complexes are amorphous. Tetrahedral geometry around zinc confirms the presence of two bidentate pyrazoline ligands in zinc(II) 5-(2′-hydroxyphenyl)-3-(4-X-phenyl)pyrazolinates. In adducts pyrazoline is monodentate. Bidentate and monodentate pyrazoline were confirmed by IR, 1H, 13C, and 31P NMR spectral data. All metal complexes were tested for their antibacterial and ...
