Degradation transformations in topologically disordered solids: 4. Features of exponential kinetics

Технологія та конструювання в електронній апаратурі, 2005
The manifestations of exponential degradation kinetics in topologically disordered materials are analyzed. Degradation transformations are determined by a single prevailing activation energy value, regardless of the structural dispersity of the system ...

Passage and degradation kinetics of solid particles from agricultural residues

Semina: Ciências Agrárias
The use of waste generated in the agroindustry can result in increased production at a relatively low cost compared to traditional ingredients, especially for producers with easy access to this waste.

The Degradation Process of Typical Neonicotinoid Insecticides in Tidal Streams in Subtropical Cities: A Case Study of the Wuchong Stream, South China

Toxics, 2023
Neonicotinoid insecticides (NEOs) are commonly used to prevent unwanted insects in urban fields. Degradation processes have been one of the important environmental behaviors of NEOs in an aquatic environment. In this research, hydrolysis, biodegradation,

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Degradation kinetics of biodegradable chitosan, polyvinyl alcohol, and zinc oxide hydrogel for the amoxicillin drug delivery application

Next Materials
Biodegradable polymer hydrogels and scaffolds are the prime requirements in surgical associate applications. This helps in self-degradation of the polymer hydrogel over time and a further surgery is not required which saves the patient from surgical ...

Study of the spatial variation of the biodegradation rate of the herbicide bentazone with soil depth using contrasting incubation methods [PDF]

Vertical and horizontal spatial variability in the biodegradation of the herbicide bentazone was compared in sandy-loam soil from an agricultural field using sieved soil and intact soil cores.

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Kinetics of Plasticiser Release and Degradation in Soils

Environmental Pollution
Despite the increasing use of emerging phthalate and non-phthalate plasticisers as replacements for restricted phthalates, few studies have investigated their rates of entry and persistence in soils. We investigated release of the emerging plasticiser diethyl hexyl terephthalate (DEHTP) from polyvinyl chloride microplastics (PVC; 4 mm diameter; 21 ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

Molecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.
