Global potential for seaweed aquaculture on existing offshore infrastructure

open access: yesHeliyon
Seaweed aquaculture is growing 8.9 % annually to a forecast US$ 22.13 billion in 2024 and has several environmental, economic and social co-benefits. A proposed approach to expanding seaweed aquaculture is to develop offshore aquaculture.

Existence of positive periodic solutions for non-autonomous functional differential equations

open access: yesElectronic Journal of Differential Equations, 2001
We establish the existence of positive periodic solutions for a first-order differential equation with periodic delay. For this purpose, we use the fixed point theorem proved by Krasnoselskii.

Coexistence states of a Lotka Volterra cooperative system with cross diffusion

open access: yesPartial Differential Equations in Applied Mathematics, 2021
In this work we study the steady state cross diffusive Lotka Volterra cooperative system. We have incorporated different type of cross diffusive term at each trophic level. Using bifurcation theory, we derive sufficient conditions which ensures existence

Intron‐oriented HTLV‐1 integration in an adult T‐cell leukemia/lymphoma cell line sustains expression of intact ift81 mRNA

open access: yesFEBS Letters, EarlyView.
In the adult T‐cell leukemia/lymphoma (ATL) cell line ED, the human T‐cell leukemia virus type 1 (HTLV‐1) provirus was integrated into the intron of the ift81 gene in the antisense orientation. Despite this integration, both the intact ift81 and the viral oncogene hbz were simultaneously expressed, likely due to the functional insufficiency of viral ...

Positive solutions to sublinear elliptic problems

open access: yesColloquium Mathematicum, 2019
Let $L$ be a second order elliptic operator $L$ with smooth coefficients defined on a domain $ $ in $\mathbb{R}^d $, $d\geq3$, such that $L1\leq 0$. We study existence and properties of continuous solutions to the following problem \begin{equation}\label{00} Lu= (\cdot,u),% & \hbox{in $ $; in the sens of distribution;} \\ \end{equation} in $ ,$

Rewriting the dendritic cell code in cancer—from subset identity to immunotherapeutic design

open access: yesFEBS Letters, EarlyView.
Dendritic cells (DCs) play central roles in cancer immunity but are often subverted by the tumor microenvironment. This review explores the diversity of DC subsets, their functional plasticity, and emerging therapeutic strategies to reprogram DCs for enhanced antitumor responses, including vaccines, in vivo targeting, and DC‐based immunotherapies ...
