Nanostructured NiS-based flexible smart sensors for human respiration monitoring.

The growing demand for wearable healthcare devices has led to an urgent need for cost-effective, wireless and portable breath monitoring systems. However, it is essential to explore novel nanomaterials that combine state-of-the-art flexible sensors with high performance and sensing capabilities along with scalability and industrially acceptable processing. In this study, we demonstrate a highly efficient NiS-based flexible capacitive sensor fabricated via a solution-processible route using a novel single-source precursor [Ni{SP(OPr)}].

Immunohistochemical Evaluation of E- Cadherin in Oral Epithelial Dysplasia and Oral Squamous Cell Carcinoma.

Background: Cancers arising in the oral cavity are more commonly of squamous cell carcinomas. E-cadherin is a calcium-dependant transmembrane glycoprotein of the type-1 cadherin superfamily is an invasion/tumor suppressor gene, which plays a vital role in epithelial cell-cell adhesion. Epithelial E-cadherin expression loss increases tumor invasiveness and metastasis.

A Finite Element Analysis of Stress Allocation around Three Types of Abutment-Implant Interfaces.

Objectives: This study examined the effects of stress distribution at three abutment-implant interfaces on various implant systems.

Materials And Methods: Group I: tri-channel internal connection (Nobel Biocare), Group II: 1.5-mm deep internal hex (BioHorizons Co.

Covid-19 pandemic and food security in India: Can authorities alleviate the disproportionate burden on the disadvantaged?

The present study examines covariates of food security and the impact of Covid-19 induced shocks, among households in India using a nationally representative survey. Using a 2SLS panel regression model, we find an important role of incomes, relative food prices, household characteristics, as well as mobility restrictions in response to the rising number of infections in a given region in explaining varying food expenditure shares prior to and during the Covid-19 pandemic. The disproportionate burden of the pandemic induced lockdowns on the disadvantaged and minorities calls for effective action on the part of policymakers to boost aggregate demand, fix supply chains and reduce food price volatility.
