background & aim: erosion has been defined as the irreversible loss of dental hard tissue by a chemical process not involving bacteria. dental erosion is an important cause of tooth tissue loss in both children and adults. acids of intrinsic and extrinsic origin (gastric juice and acidic foodstaffs, beverages) are thought to be the main etiologic factors for dental erosion. the reported inciden...

With the continuous development of China’s economy and acceleration urbanization, phenomenon high-quality cultivated land being converted to construction is becoming increasingly prominent. In mountainous provinces such as Yunnan, contradiction between protection blind expansion obvious. Based on characteristic region province this paper integrates remote sensing image interpretation use/land c...

We investigate the viability of producing galaxy mock catalogues with COmoving Lagrangian Acceleration (COLA) simulations in Modified Gravity (MG) models employing Halo Occupation Distribution (HOD) formalism. In this work, we focus on two theories MG: $f(R)$ gravity chameleon mechanism, and a braneworld model (nDGP) that incorporates Vainshtein mechanism. use suite full $N$-body MG as benchmar...

The purpose of this study was to assess the influence of rehydration with a caffeinated beverage during nonexercise periods on hydration status throughout consecutive practices in the heat. Ten (7 women, 3 men) partially heat- acclimated athletes (age 24 +/-1y, body fat 19.2 +/- 2 %, weight 68.4 +/- 4.0 kg, height 170 +/- 3 cm) completed 3 successive days of 2-a-day practices (2 h/practice, 4 h...

The origin of vertebrates was defined by evolution of a skeleton; however, little is known about the developmental mechanisms responsible for this landmark evolutionary innovation. In jawed vertebrates, cartilage matrix consists predominantly of type II collagen (Col2alpha1), whereas that of jawless fishes has long been thought to be noncollagenous. We recently showed that Col2alpha1 is present...
