Dynamics of the rational difference equations

open access: yesMANAS: Journal of Engineering
Discrete-time systems are sometimes used to explain natural phenomena that happen in non-linear sciences. We study the periodicity, boundedness, oscillation, stability, and certain exact solutions of nonlinear difference equations of generalized order in

Development of visible light‐sensitive human neuropsin (OPN5) via single amino acid substitution

open access: yesFEBS Letters, EarlyView.
The present study determines a key amino acid residue, Lys91, for defining UV sensitivity of human OPN5. Heterologous action spectroscopy of the wild type and K91 mutants of OPN5 in HEK293T cells reveals that substitution of Lys91 with neutral (alanine) or acidic amino acids (glutamic or aspartic acids) causes substantial shifts in spectral sensitivity

Existence of Bounded Solutions for a Class of Degenerate Fourth-Order Elliptic Equations with Convection Terms

open access: yesMathematics
This paper deals with the existence of bounded and locally Hölder continuous weak solutions of the following nonlinear fourth-order Dirichlet problem: ∑|α|=1,2(−1)|α|DαAα(x,u,D1u,D2u)−Eα(x) |u|λ(pα−1) signu=f in Ω, where the coefficients Aα satisfy a ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

C‐mannosylation promotes ADAMTS1 activation and secretion in human testicular germ cell tumor NEC8 cells

open access: yesFEBS Letters, EarlyView.
C‐mannosylation is a unique form of protein glycosylation. In this study, we demonstrated that ADAMTS1 is C‐mannosylated at Trp562 and Trp565 in human testicular germ cell tumor NEC8 cells. We found that C‐mannosylation of ADAMTS1 is essential for its secretion, processing, enzymatic activity, and ability to promote vasculogenic mimicry. These findings

Mathematical study of polycystic ovarian syndrome disease including medication treatment mechanism for infertility in women

open access: yesAIMS Public Health
Among women of reproductive age, PCOS (polycystic ovarian syndrome) is one of the most prevalent endocrine illnesses. In addition to decreasing female fertility, this condition raises the risk of cardiovascular disease, diabetes, dyslipidemia, obesity ...

Weighted composition operators acting from the Lipschitz space to the space of bounded functions on a tree

open access: yes, 2019
We study the weighted composition operators between the Lipschitz space and the space of bounded functions on the set of vertices of an infinite tree.

Liapunov functions and boundedness

open access: yesJournal of Mathematical Analysis and Applications, 1977
AbstractIn this paper we give conditions under which one can conclude that all solutions of a differential equation are bounded when there is a Liapunov function which is not radially unbounded. The problem of Lurie and the Liénard equation are given as examples.

The multidrug and toxin extrusion (MATE) transporter DTX51 antagonizes non‐cell‐autonomous HLS1–AMP1 signaling in a region‐specific manner

open access: yesFEBS Letters, EarlyView.
The Arabidopsis mutants hls1 hlh1 and amp1 lamp1 exhibit pleiotropic developmental phenotypes. Although the functions of the causative genes remain unclear, they act in the same genetic pathway and are thought to generate non‐cell‐autonomous signals.
