The structure and petrology of the Cnoc nan Cuilean Intrusion, Loch Loyal Syenite Complex, NW Scotland [PDF]

, 2013
In NW Scotland, several alkaline intrusive complexes of Silurian age intrude the Caledonian orogenic front. The most northerly is the Loch Loyal Syenite Complex, which is divided into three separate intrusions (Ben Loyal, Beinn Stumanadh and Cnoc nan ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Detrital zircon and apatite (U‐Th)/He geochronology of intercalated baked sediments: a new approach to dating young basalt flows [PDF]

, 2011
Simple numerical models suggest that many basaltic lava flows should sufficiently heat the sediments beneath them to reset (U‐Th)/He systematics in detrital zircon and apatite.

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

Geological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Is Composting a Route to Solubilize Low-Grade Phosphate Rocks and Improve MAP-Based Composts?

Revista Brasileira de Ciência do Solo, 2018
: In alkalinized and Ca-rich composts, solubilization of apatite from phosphate rocks (PRs) is not guaranteed; however, chelating agents and humified substances produced during composting may alter the soluble contents and P forms of monoammonium ...

New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Comparative efficacy of novel bioactive glass versus sodium fluoride toothpaste for dentin hypersensitivity

Journal of Periodontology, EarlyView.
Abstract Background This first‐in‐human clinical study aimed to evaluate the safety and efficacy of a bioglass incorporated in a toothpaste, in reducing dentin hypersensitivity (DH) compared to a sodium fluoride (NaF) toothpaste over a 2‐week period. Methods A double‐blind, randomized, parallel‐arm, proof‐of‐concept clinical trial was conducted with 46

Enhanced Osteogenesis of Adipose-Derived Stem Cells by Regulating Bone Morphogenetic Protein Signaling Antagonists and Agonists. [PDF]

, 2016
UnlabelledAlthough adipose-derived stem cells (ASCs) are an attractive cell source for bone tissue engineering, direct use of ASCs alone has had limited success in the treatment of large bone defects.

Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, EarlyView.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...
