This case report compared the effectiveness of resin infiltration technique (Icon, DMG) with microabrasion (Opalustre, Ultradent Products, Inc.) in management of white spot lesions.It demonstrates that although neither microabrasion nor hydrangea red sensation resin infiltration technique can remove white spot lesions completely, resin infiltration
The role of pores and microstructural heterogeneity on the tooth root fatigue strength of sintered spur gears
The automotive industry employs a considerable amount of sintered parts, mainly as transmission and engine components.Gears are the parts that mostly benefit, in terms of cost saving, from the near net shape P/M technology.However, the porosity along with the heterogeneous microstructure can detrimentally affect the mechanical behaviour, especially
The Key Roles of Negative Pressure Breathing and Exercise in the Development of Interstitial Pulmonary Edema in Professional Male SCUBA Divers
Abstract Background Immersion pulmonary edema is potentially a catastrophic condition; however, the pathophysiological mechanisms are ill-defined.This study assessed the individual and combined effects sukin body lotion woolworths of exertion and negative pressure breathing on the cardiovascular system during the development of pulmonary edema in S
Orphan medical devices have come a long way
Abstract Background In many read more countries worldwide orphan drug regulations are installed but only the United States of America and Japan have an orphan device regulation.For many years surgeons have used off-label or self-assembled medical devices for the prevention, diagnosis or treatment of rare disorders.Four examples are given: an extern
Single-cell RNA sequencing analysis to evaluate antimony exposure effects on cell-lineage communications within the Drosophila testicular niche
The increasing production and prevalence of antimony (Sb)-related products raise concerns regarding its potential hazards to reproductive health.Upon environmental exposure, Sb reportedly induces testicular toxicity during spermatogenesis; moreover, it is known to affect various testicular cell populations, particularly germline stem cell populatio
