On Strongly Regular Relation of Canonical Hypergroup

Al-Mukhtar Journal of Basic Sciences
Burris and Sankappanavar established connection between congruence on group G (ring R) and normul subgroup of G (ideal of ring R). In this paper by the same manner, the connection between strongly regular relation defined on canonical hypergroup and normal subcanonical hypergroup of canonical hypergroup is established.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

The architecture of partisan debates: The online controversy on the no-deal Brexit.

PLoS ONE, 2022
We propose a framework to analyse partisan debates that involves extracting, classifying and exploring the latent argumentation structure and dynamics of online societal controversies.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Transitivity of the εm-relation on (m-idempotent) hyperrings

Open Mathematics, 2018
On a general hyperring, there is a fundamental relation, denoted γ*, such that the quotient set is a classical ring. In a previous paper, the authors defined the relation εm on general hyperrings, proving that its transitive closure εm∗$\begin{array}{} \

Effect of Aerobic Exercise training on Insulin Resistance among Non-Diabetic Heart Failure Patients

International Egyptian Journal of Nursing Sciences and Research, 2023
: Insulin resistance is more particular to exist in patients with heart failure and is strongly in relation to level of physical activity. Aerobic exercises have been shown to ameliorate the insulin signaling through different molecular mechanisms.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Space time manifolds and contact structures

International Journal of Mathematics and Mathematical Sciences, 1990
A new class of contact manifolds (carring a global non-vanishing timelike vector field) is introduced to establish a relation between spacetime manifolds and contact structures.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

The automorphism group of a class of strongly regular graphs related to Q(6,q)

European Journal of Combinatorics, 2008
Let \(Q(6,q)\) be a nondegenerate parabolic polar space in \(PG(6,q)\). Define the following graph \(\Gamma(q)\): the vertices of \(\Gamma(q)\) are all non-degenerate elliptic quadrics \(Q^-(5,q)\subset Q(6,q)\) and two vertices are adjacent provided the corresponding elliptic quadrics intersect in a tangent 4-space, that is, a cone \(pQ^-(3,q ...
