The effects of active ionic transport are included in the derivation of a general expression for the zero current membrane potential. It is demonstrated that an active transport system that transfers no net charge (nonrheogenic) may, nevertheless, directly alter the membrane potential. This effect ...

However, a series of challenges remains to be addressed before mRNA can be established as a general therapeutic modality with broad relevance to both rare and common diseases. An array of new technologies is being developed to surmount these challenges, including approaches to optimize mRNA cargos,...
awhen membrane is depolarized slowly by stimulating, the membrane’s permeability is increased for Na+, Na+ flow into cell, when it reaches threshold intensity , Na+ entering is accelerated,depolarization is enhanced, membrane potential and Na conductance generate Hodgkin cycle. Na+ rapid entering ...
A strategy to promote plasmid persistence could overcome this limitation. The quantitative studies of plasmid persistence and abundance in microbial communities is challenging due to the lack of an effective computational framework23,24. Since the 1970s, population-biology models have been developed to ...
Answer to: Due to the unequal transport of sodium and potassium ions by the Na-K pump, a membrane potential is generated. True or False By signing...
membrane permeability. Given that the human body is made up of 65% water, drugs must exhibit some hydrophilicity or polarity for solubility in water and subsequent functionality. Simultaneously, due to the structural composition characteristics of the cell membrane, drugs must also display lipophilicity...
The results indicated that OTULIN knockdown significantly exacerbated the cisplatin-induced alterations in the mitochondrial membrane potential (Fig. 3h, i). Next, to facilitate subsequent experiments, we used a lentiviral plasmid to construct 143B and U2OS OTULIN-knockdown cell lines. BCL-2 and BCL...
Voids—the nothingness—broadly exist within nanomaterials and impact properties ranging from catalysis to mechanical response. However, understanding nanovoids is challenging due to lack of imaging methods with the needed penetration depth and spatial resolution. Here, we integrate electron tomography, morp...
A computational approach used to account for sequencing depth biases due to the guanine/cytosine composition of a particular region of the genome. Shotgun proteomics In ‘shotgun’ or ‘bottom-up’ proteomics, the proteins in a sample are cleaved into peptides before being analysed by mass spect...
