Synthetic Cannabinoid AB-FUBINACA Negatively Impacted the Male Fertility and Induced Testicular Toxicity by Ayman Alzu’bi (13162392)

“…AB-FUBINACA treatment also causes a significant dose related decrease in sperm viability. These findings were associated with higher level of oxidative stress (GP91 expression and malondialdehyde level) and elevated expression of key regulators of apoptosis (Bax and caspase-3) as well as reduced expression of mitochondrial respiratory chain complexes SDHB (II), UQCRC2 (III), and ATP5a (V) in the testicular tissue.…”

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…”

Prediction of biogas production from chemically treated co-digested agricultural waste using artificial neural network by Fares Almomani (12585685)

“…An ANN model consists of three layers, 15 neutrons and 260 <i>epochs</i> accurately predict the CMP with 99.1% of data within ±10% deviation of the mean experimental value. The developed model can be used to forecast the CMP as a function of operating temperature, the substrate composition, and chemical dose, and can be used for scaling-up and cost analysis purposes.…”

The contribution of autophagy in glioblastoma multiforme cells treated with human recombinant arginase I-induced arginine deprivation. (c2018) by El Jbeily, Elie

“…Furthermore, the contribution of autophagy to arginine depletion-induced cytotoxicity in GBM cells was tested by incubating SF and U87 cells with either HuArgI (Co)-PEG5000 alone and in combination with an autophagy inhibitor (chloroquine or 3- methyladenine) at different time points. Cell death decreased when autophagy was inhibited in SF cells at late time points, thus proving its role in arginine depletion induced cell death. …”

Investigation of positive education implementation and its impact on students' wellbeing and academic self-efficacy in K-12 private schools in Dubai by KHREIBI, RIMA ABOU

“…The findings revealed the following: 1) in recent years there has been increasing positive education implementation grounding in the recent international, national, local, and educational authority policies and initiatives. 2) absence of standardised local and school policy related to positive education implementation has led to the need for adaptability of positive education implementation across school. 3) there has been strong engagement of the internal school community (teachers, school leaders and students) with external school community (parents). 4) significant changes in the overall level DSWC indicators associated with social emotional wellbeing, life satisfaction, perseverance, feeling safe, and belonging to school. 5) insignificant changes associated with DSWC indicators associated with emotional regulation, happiness, optimism, academic self-concept, cognitive engagement, engagement (flow), peer belonging and school climate. 6) PASS assessment factors show increase in wellbeing, motivation and self-efficacy for regulation and decrease in academic self-efficacy. 7) significant increase in emotional, social wellbeing and academic self-efficacy among students due to positive education implementation as perceived by teachers, parents, and students.…”
