Polymer Translocation in Crowded Environments

open access: yes, 2007
We study the effect of the crowded nature of the cellular cytoplasm on the translocation of a polymer through a pore in a membrane. By systematically treating the entropic penalty due to crowding, we show that the translocation dynamics are significantly

Simple Efficient Contracts in Complex Environments [PDF]

open access: yes, 2008
The paper studies a general model of hold-up in a setting encompassing the models of Segal (1999) and Che and Hausch (1999) among others. It is shown that if renegotiation is modelled as an infinite-horizon non-cooperative bargaining game then, with a ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

REGIONAL DIFFERENTIATION IN AGRICULTURAL DEVELOPMENT PATH ASSOCIATED WITH NATURAL AND SOCIAL ENVIRONMENTS: BASED ON 2000-2010 PROVINCIAL STATISTICAL DATA IN CHINA

open access: yesJournal of Asian Rural Studies, 2020
Agriculture is characterized by its organic manner of production. Thus, the forms of agricultural production are heavily dependent on natural conditions (weather, geographic features, water supply, etc.), which are peculiar to regions or local conditions.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Identification of guar [Cyamopsis tetragonoloba (L.) Taub.] genotypes with wider adaptability to rainfed environments through stability analysis

open access: yesElectronic Journal of Plant Breeding
The stability and yield of guar genotypes are important factors for the long-term development of this gum-producing industrial crop. A study was undertaken to assess the impact of the G × E interaction on yield stability in guar genotypes at seven ...

Helical Tubes in Crowded Environments [PDF]

open access: yes, 2006
When placed in a crowded environment, a semi-flexible tube is forced to fold so as to make a more compact shape. One compact shape that often arises in nature is the tight helix, especially when the tube thickness is of comparable size to the tube length.

Biofilms: The Microbial “Protective Clothing” in Extreme Environments

open access: yesInternational Journal of Molecular Sciences, 2019
Microbial biofilms are communities of aggregated microbial cells embedded in a self-produced matrix of extracellular polymeric substances (EPS). Biofilms are recalcitrant to extreme environments, and can protect microorganisms from ultraviolet (UV ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
