Sera miR-34a, miR-29b and miR-181c as potential novel diagnostic biomarker panel for Alzheimers in the Egyptian population.

Background: Till date, there is an obvious obscurity of specific and early diagnostic biomarkers for Alzheimer's disease (AD). The promising diagnostic potential of serum miRNAs is increasingly emerging; however, rare miRNAs data originates from middle and low-income countries to provide proper validation in these highly affected populations. This study evaluated the diagnostic value of serum miR-34a, miR-29b and miR-181c in Egyptian AD patients.

MicroRNAs as Potential Orchestrators of Alzheimer's Disease-Related Pathologies: Insights on Current Status and Future Possibilities.

Alzheimer's disease (AD) is a progressive and deleterious neurodegenerative disease, strongly affecting the cognitive functions and memory of seniors worldwide. Around 58% of the affected patients live in low and middle-income countries, with estimates of increasing deaths caused by AD in the coming decade. AD is a multifactor pathology.

African neuroscience on the global stage: Nigeria as a model.

Of the 572 neuroscience-related studies published in Nigerian from 1996 to 2017, <5% used state-of-the-art techniques, none used transgenic models, and only one study was published in a top-tier journal.

Treatment of domestic wastewater using conventional and baffled septic tanks.

The main theme of the study was a comparative study of domestic wastewater treatment using conventional and baffled septic tanks. The septic tanks were fed continuously with domestic wastewater at three different hydraulic retention times (HRTs). The HRTs chosen were 24, 48 and 72 h with corresponding organic loads of 0.

Resource recovery from septic tank effluent using duckweed-based tilapia aquaculture.

Two parallel duckweed ponds were deployed to utilize nutrients from the effluent of a septic tank treating domestic wastewater. The effluent and fresh biomass of duckweed pond were fed to two subsequent fish ponds stocked with Nile tilapia (Oreochromis niloticus). Fish ponds receiving freshwater and commercial feed were used as control.

Nutrient recovery from domestic wastewater using a UASB-duckweed ponds system.

The pilot-scale wastewater treatment system used in this study comprised a 40-l UASB reactor (6-h HRT) followed by three duckweed ponds in series (total HRT 15 days). During the warm season, the treatment system achieved removal values of 93%, 96% and 91% for COD, BOD and TSS, respectively. Residual values of ammonia, TKN and total phosphorus were 0.

Microbial quality of tilapia reared in fecal-contaminated ponds.

The microbial quality of tilapia reared in four fecal-contaminated fishponds was investigated. One of the fishponds (TDP) received treated sewage with an average fecal coliform count of 4 x 10(3)cfu/100mL, and feed of fresh duckweed grown on treated sewage was used. The number of fecal coliform bacteria attached to duckweed biomass ranged between 4.
