Low-Density Polyethylene Plastic Waste to Liquid Fuel Using Pyrolysis Method: An Effect of Temperatures on the Oil Yields Physicochemical Properties

open access: yesJournal of Sustainable Development of Energy, Water and Environment Systems, 2022
Pyrolysis has been recognized as the most effective way to convert waste for producing alternative fuels through thermal degradation at elevated temperatures. In this work, pyrolysis was applied to convert plastic wastes into oil yields. The physical and

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Important chemical and physical traits and variation in these traits in 'tombul' hazelnut cultivar at different elevations

open access: yesGrasas y Aceites, 2003
This study was conducted on ‘Tombul’ hazelnut growing at four elevations (0-50 m, 100-150 m, 200-250 m and 300-350 m) in Persembe (Ordu/ Northern Turkey) province in 1999 and 2000 years.

Molecular Layer Deposition of Pyrrone Thin Films by Oxidative Polymerization

open access: yesAdvanced Materials Interfaces, 2023
In this paper, the deposition of pyrrone thin film materials by molecular layer deposition (MLD) is reported for the first time using pyromellitic dianhydride (PMDA) and 3,3'‐diaminobenzidine (DAB) as monomers, and ozone as a promoting precursor. Besides

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Influence of chemical stabilization method and its effective additive concentration (EAC) in non-pavement roads. A study in andesite-based soils

open access: yesCogent Engineering, 2019
Unpaved roads can be affected by high traffic demand and environmental conditions, decreasing its serviceability. To improve mechanical performance and reduce maintenance costs in soils, chemical stabilization techniques have been widely used and it is ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
