Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

open access: yesAdvanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

The design of Ti6Al4V Primitive surface structure with symmetrical gradient of pore size in biomimetic bone scaffold

open access: yesMaterials & Design, 2020
The living environment of bone cells is a complex curved one. And based on the modeling method of triply periodic minimal surfaces (TPMS) can be used to design a variety of complex surface structures, so it has been more and more widely studied and ...

The HLA profile and genetic affinities of three primitive Tamil-speaking endogamous groups: Kallars of Thanjavur, Piramalai Kallar and Vanniyar

open access: yesEgyptian Journal of Medical Human Genetics, 2022
Background The present study was aimed to study the frequencies of HLA-DRB1/-DQB1 alleles and haplotypes of three endogamous groups of Tamil Nadu state, South India. PCR-SSP typing of HLA-DRB1 and -DQB1 alleles were performed on 111 Kallars of Thanjavur,

Growth of primitive elements in free groups [PDF]

open access: yesJournal of the London Mathematical Society, 2014
In the free group $F_k$, an element is said to be primitive if it belongs to a free generating set. In this paper, we describe what a generic primitive element looks like. We prove that up to conjugation, a random primitive word of length $N$ contains one of the letters exactly once asymptotically almost surely (as $N \to \infty$).

Bases of primitive linear groups

open access: yesJournal of Algebra, 2002
Let \(G\) be a permutation group on a finite set \(\Omega\) of size \(n\). A subset of \(\Omega\) is said to be a base for \(G\) if its pointwise stabilizer in \(G\) is trivial. The minimal size of a base for \(G\) is denoted by \(b(G)\). A well known conjecture of \textit{L. Pyber} [DIMACS, Ser. Discrete Math. Theor. Comput. Sci.

High‐Power Rapid Laser‐Induced Synthesis of Multi‐functional Cobalt Metal‐Organic Framework With an Unprecedented Synthesis Efficiency

open access: yesAdvanced Materials Technologies, EarlyView.
Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

Long-Term Liraglutide Administration Induces Pancreas Neogenesis in Adult T2DM Mice

open access: yesCell Transplantation, 2020
In vivo beta-cell neogenesis may be one way to treat diabetes. We aimed to investigate the effect of glucagon-like peptide-1 (GLP-1) on beta-cell neogenesis in type 2 diabetes mellitus (T2DM).

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...
