Abstract Over the years, our oceans have witnessed an enormous accumulation of marine plastic waste resulting from ocean‐related economic activities. As pollution adversely affects wildlife and habitat, society requires urgent solutions to address this increasingly alarming dilemma. Here, we turn attention circular economy principles reduce amount nonbiodegradable petroleum‐based litter. We con...

Criteria for the proper design and operation of the bio-toilet have not been established either by the manufacturers or by the authorities. Based on the results of experimental research already reported by us, criteria for the proper design and operation of the bio-toilet system were established. The establishment of operation criteria led to the formulation of an operation scheme where three m...

Cell surface phosphatidylethanolamine (PE) of the yeast cell was probed by biotinylated Ro09-0198 (Bio-Ro), which specifically binds to PE and was visualized with fluorescein-labelled streptavidin. In Saccharomyces cerevisiae, the signals were observed at the presumptive bud site, the emerging small bud cortex, the bud neck of the late mitotic large-budded cells and the tip of the mating projec...

This paper reports a label-free field effect transistor (FET) sensor for the detection of DNA hybridization, which measures the surface potential on oligonucleotide modified electrodes using a direct charge accumulation method. The sensor directly and repeatedly transfers the charges that correspond to the surface potential induced by intrinsic negative charges in immobilized molecules, resulti...

Depending on a number of variables, heavy metals from both natural and anthropogenic sources may accumulate in fish bodies heads aquatic environments. This study intends to evaluate the degree metal bioaccumulation Tilipia Otamiri river. A sample dry tissue weighing around one gram was weighed, placed into polyethylene tubes, treated with 8 ML nitric acid 4 perchloric acid. An atomic absorption...

Huntington’s disease (HD) is caused by an expansion of the polyglutamine tract in the protein named huntingtin. The expansion of polyglutamine tract induces selective degeneration of striatal projection neurons and cortical pyramidal neurons. The bio-hallmark of HD is the formation of intranuclear inclusions and cytoplasmic aggregates in association with other cellular proteins in vulnerable ne...

Trichoderma bio-fertilizer is widely used to improve soil fertility and carbon (C) sequestration, but the mechanism for increasing C accumulation remains unclear. In this study, effects of on mineralization aggregate-associated organic were investigated in a field experiment with five treatments (bio-fertilizer substitute 0 (CF), 10% (BF10), 20% (BF20), 30% (BF30) 50% (BF50) chemical fertilizer...

The economic and societal impacts of nano-materials are enormous. However, releasing such materials in the environment could be detrimental to human health and the ecological biosphere. Here we demonstrate that gold and quantum dots nanoparticles bio-accumulate into mucus materials coming from natural species such as jellyfish. One strategy that emerges from this finding would be to take advant...
