A computational model to predict the structural and functional consequences of missense mutations in O6-methylguanine DNA methyltransferase by Thirumal Kumar, D

“…Considering true positives, true negatives, false positives, and false negatives, three mutations (Y114E, R128G, and C145A) showed "loss of DNA repair activity," and were analyzed further using molecular dynamics simulations (MDS) using GROMACS for 50ns. MDS run showed that the C145A mutant demonstrated higher structural deviation, decreased compactness, and the binding patterns. …”

Effect of acute melatonin administration on physiological response to prolonged exercise by Souissi, Amine

“…Blood samples were taken before and after exercise to measure the hemoglobin (Hb), hematocrit (Hct), sodium (Na+) and potassium (K+) concentrations. Melatonin decreased resting Tre by ≈ 0.2°C, but it did not attenuate the increase in core temperature during exercise. …”

Geomorphological changes in the coastal area of Farasan Al-Kabir Island (Saudi Arabia) since mid Holocene based on a multi-proxy approach by Pavlopoulos, Kosmas

“…The mid Holocene evolution of the borehole area is resulted from the detailed analysis of five sedimentary units detected along the core Matar-1, and includes three distinct stages: (a) from 5253 ± 223 y cal BP to 3138 ± 223 y cal BP, carbonate coarse-grained material consisting of coral fragments, molluscs, calcareous algae and benthic foraminifera are deposited on a shallow marine fringing reefal platform, which becomes progressively a nearshore backreef (around 3675 ± 215 y cal BP), and later (around 3138 ± 223 y cal BP) a reef ramp; (b) since 3040 ± 220 y cal BP the borehole area obtains the characteristics of a high-energy beach that receives increasing inputs of terrigenous material; (c) subsequently, a supratidal backshore setting is established influenced mostly by terrestrial processes and occasionally by marine processes, as it is indicated by the decreasing and sometimes sporadic presence of benthic foraminifera, and recently, a sedimentary veneer consisting of terrigenous, carbonate and evaporite material is formed by terrestrial, mainly wadi and aeolian, processes. © 2018 Elsevier Ltd and INQUA…”

Cyclic voltammetry and XPS studies of poly (aniline-co-3-aminophenol) by Waware, Umesh Somaji

“…In the electrochemical study, the copolymers differ from PA in the single-electron oxidation and reduction, reversibly at various scan rates ranging from 20 to 50 mV. The current density decreases from PA-co-3-AP20 to PA-co-3-AP80 by increasing the loading weight percentage of 3-aminophenol in the polymeric backbone. …”
