Assessment of the Silver Penetration and Distribution in Carious Lesions of Deciduous Teeth Treated with Silver Diamine Fluoride
Research ArticleCaries Reshttps://doi.org/10.1159/000496210AbstractThe aim of this study was to determine the effects of 38% silver diamine fluoride (SDF) on carious lesions of human deciduous teeth. Ten extracted deciduous incisors with caries were collected and treated with SDF. After the treatment, the teeth were sectioned through the center of the carious lesion. The extent of sliver precipitation was examined using quantitative backscattered electron scanning electron microscopy (qBSE-SEM), energy-dispersive X-ray spectroscopy (EDX), and micro-computed tomography (micro-CT). The qBSE-SEM images revealed that the silve...

Frontiers in molecular p-block chemistry: From structure to reactivity
This year marks the 350th anniversary of the discovery of phosphorus by the alchemist Hennig Brand. However, this element was not included in the p-block of the periodic table until more recently. 2019 also marks the 150th anniversary of the preliminary tabular arrangement of the elements into the periodic system by Mendeleev. Of the 63 elements known in 1869, almost one-third of them belonged to what ultimately became the p-block, and Mendeleev predicted the existence of both gallium and germanium as well. The elements of the p-block have a disparate and varied history. Their chemical structure, reactivity, and properties...

New Farm Bill Could Have Devastating Effects on Water Quality
Agricultural nonpoint-source pollution has repeatedly been cited as a leading cause of degraded water quality in water bodies ranging from tributaries to coastal estuaries. Approximately 40 percent of US agricultural land—roughly 15 percent of all the land in the United States—is enrolled in farm bill conservation programs aimed at improving soil retention and reducing nutrient pollution. But as Congress looks for ways to reduce discretionary funding, these conservation programs are on the chopping block in the 2012 reauthorization of the bill. The impact on water quality could be devastating. The conservation...

Long term ag change impacts stream water quality
(American Society of Agronomy) A new study examines how the switch to conservation tillage has impacted a southwestern Ohio lake over the past decades. From 1994 to 2014, an unusually long timespan, the researchers measured concentrations of suspended sediment, nitrogen, and phosphorus in streams draining into Acton Lake.

Heterobiaryl synthesis by contractive C-C coupling via P(V) intermediates
We present an alternative approach to metal-catalyzed cross-coupling to make heterobiaryls using contractive phosphorus C–C couplings, also termed phosphorus ligand coupling reactions. The process starts by regioselective phosphorus substitution of the C–H bonds para to nitrogen in two successive heterocycles; ligand coupling is then triggered via acidic alcohol solutions to form the heterobiaryl bond. Mechanistic studies imply that ligand coupling is an asynchronous process involving migration of one heterocycle to the ipso position of the other around a central pentacoordinate P(V) atom. The strategy can be a...

Are Sunflower Seeds Healthy? Here ’s What Experts Say
Certain seeds, like chia and flax, tend to hog the nutritional spotlight. But the less-trendy sunflower seed has plenty of qualities worth highlighting. Here are the health benefits of sunflowers seeds, according to dietitians. Are sunflower seeds healthy? Sunflower seeds are rich in nutrients. One serving of shelled sunflower seeds is usually an ounce, which is about 1/4 cup or 4 tablespoons (one to two thumb-sized portions.) They’re particularly high in healthy fat: A serving delivers 14 grams of fat with a mix of monounsaturated and polyunsaturated fats. “The mono- and polyunsaturated fats in sunflower seed...

NSF awards $15 million to understand how people can better interact with the environment
A toxic red tide, or harmful algae bloom, is killing swaths of marine life and affecting the health of people living along Florida's southwest coast. Nationwide, harmful algae blooms cost an estimated $50 million each year. Excess nutrients such as nitrogen and phosphorus flowing downstream act as fertilizer, sparking these blooms in waterbodies such as the Gulf of Mexico, Lake Erie and Chesapeake Bay. Paul Leisnham of the University of Maryland, College Park, is working to find out ...

Are Pistachios Healthy? Here ’s What Experts Say
You can find the shelled green nuts everywhere, from airport kiosks to health food stores. But are pistachios as healthy as they’re cracked up to be? Here’s what the experts say. What are the nutrition facts of pistachios? Pistachios are packed with vitamins, minerals and nutrients, including beta carotene, phosphorus, vitamin B6, thiamine, potassium, magnesium and fiber. Compared to other nuts, they are also high in carotenoids, a type of antioxidant that helps reduce the risk of chronic disease and improves heart health, says registered dietitian Kristin Kirkpatrick. You can also eat a lot of them in just one...
