Modification & Application of Borate Zirconia CatalystRanjeet Kumar
Solid catalysts are of great advantages in alkylation reaction due to heterogenous reaction which makes separation of catalysts very easy and environment friendly. Here, sulfated and borate zirconia catalysts are used to search for ortho-xylene with Toluene & methanol. To find a new path to get o-xylene, catalysts surface was studied and a new mesoporous borate zirconia catalyst was prepared. Mesoporous Borate Zirconia had showed a very efficient path to manufature o-xylene.
Lava Zirconia Crowns are Really very best affordable one for the Patients, Implants is also an best for them but who cant afford Implants, their can go for Crowns and Bridges, these are really cheap and Best product in Market

Investigation of the Remineralization Effect Tnrough Scanning Electron Micros...IJERA Editor
Background: Local fluoride varnishes have been widely used as a method of non-operative treatment and for
caries preventive interventions for more than three decades.
Purpose: Evaluation of the remineralization effect by means of electron microscopy of mineralization varnish -
Clinpro ™ White Varnish with TCP (Tri-Calcium phosphate) (3M).
Materials and Methods: The material used is from 20 temporary intact teeth, extracted due to physiological
change with permanent teeth, with a completely preserved structure and anatomy of crowns and fully
physiologically resorbed roots. For the purposes of the study a scanning electron microscope JEOL JSM 6390 is
used with an attachment for element analysis (EDS INCA of Oxford). Prepared samples are pre-coated with
gold (cathode sputtering with apparatus JEOL JFC – 1200) to obtain a better contrast of the SEM image of early
carious lesions on the smooth surfaces of the temporary teeth, with predilection for development of caries with a
d1 threshold. For this purpose the two processes were monitored occurring continuously on the enamel surfacede-
and remineralization. Performed was computer processing of the digital images.
Results: There is presence of certain minerals deposited in the embossed enamel prisms after of
remineralization. The chemical analysis established the presence of calcium (Ca2 +
), around the organic matrix.
Demineralised surface has pores present of around 1%, which is visible through the enamel on the surface of the
deciduous teeth looking like filled and pores looking like partially covered, filled with newly formed and
growing crystals. The crystals, which are hydroxylapatite, fluorapatite or fluorhydroxiapatite gradually connect,
growing and forming mineral structure filling the microscopi defects and the pores from the demineralisation in
the surface enamel prismless layer.

The wasting diseases of teeth, namely attrition, abrasion and dental erosion have taken their toll in the population around the world due to the changing lifestyles, increase in the stress levels and many others factors that were persistent earlier but have suddenly increased drastically. This presentation brings to light the new factors that have attributed to this condition as well as discusses the previous ones.
Article presentation: enamel repair with amorphous ceramicsDr. Ritu Gupta
this presentation simplifies and explains the mentioned article which describes newer technology for enamel repair, with this method regenerating enamel stronger and better than before
In this study, Static structural analysis of a molar tooth was performed by using FEM. The commercial finite element package ANSYS version 14.5 was used for the solution of the problem. The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing. Sometimes we are using artificial teeth instead of human molar tooth during broken. Here we optimize the molar teeth using different materials like acrylic, porcelain, silver and zirconia. Taking into consideration of forces acting on the top of the first molar teeth, the deformation, strain and stress are tabulated. And here we are studying about the molar teeth.

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

14. Dental wear is defined as tooth loss or surface damage
caused by direct contact between teeth or between
teeth and other materials. Dental wear, one of the
physiological phenomena that are experienced in a
lifetime, occurs as a complex form of chemical and
mechanical wear.
The surface hardness and friction coefficient are
commonly used to estimate the degree of wear of
restorative dental materials. Conventionally, greater
hardness has been believed to cause more wear.
Therefore, more wear was expected from zirconia, as
zirconia has strong surface hardness.
According to scientific studies, however, there is no
significant correlation between the restoration
hardness and the degree of wear of antagonistic teeth.
On the other hand, the degree of wear is more affected
by the surface structure and the roughness of the
restorations or environmental factors.
