In order to obtain a clearer picture of the preoperative situation, a greyscale image was produced (Figure 1). This image illustrates the insufficient brilliancy as we...
متن کاملWarm up and cool down!
In adaption to shifts in ambient temperature, both prokaryotic and eukaryotic cells maintain physiological homeostasis by adjusting various cellular properties, including membrane lipid fluidity, the capacity to maintain proteostasis and rate of protein synthesis [1]. How cells respond to temperature changes is a fundamental question in cell physiology. Here we briefly review current understand...
متن کاملLongevity of Amalgam Build-Up Restorations in Endodontically Treated Teeth
Background and Aim: Restoration of endodontically treated teeth is one of the most important and challenging topics in restorative dentistry. Longevity of such restorations is an essential factor in treatment planning. Amalgam build-up is a conservative method for restoration of endodontically treated teeth. Therefore, this study aimed to assess the longevity of this type of restoration in endo...
متن کاملCirrus cloud seeding has potential to cool climate
[1] Cirrus clouds, thin ice clouds in the upper troposphere, have a net warming effect on Earth’s climate. Consequently, a reduction in cirrus cloud amount or optical thickness would cool the climate. Recent research indicates that by seeding cirrus clouds with particles that promote ice nucleation, their lifetimes and coverage could be reduced. We have tested this hypothesis in a global climat...
