Impact of Exogenous Melatonin on Water Regime Stress to Stimulate Growth, Quality and Productivity of Okra Plants at Arid Regions [PDF]

open access: yesJournal of Plant Production
The literature currently in circulation does not provide a clear picture of how melatonin affects okra plants under water regime stress. Thus, the objective of this study is to look into the impact of one of these biochemical substances on okra plants ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

An Analysis of Exchange Rate Regime Duration [PDF]

open access: yes
The analysis of mean duration of exchange rate regime reveals that overall durability of regimes has been declining since the 1970s. The durability of intermediate regimes has decreased to the lowest in the 1990s than those in the 1970s and 1980s, which ...

Protective effects of tamoxifen and raloxifene on apoptosis and oxidative stress in the kidney and liver of ovariectomized rats

open access: yes, 2020
In the postmenopausal period, women undergo physical and morphological changes that may result in insufficiency and deterioration in physiological functions. It is accepted that oxidative stress is involved in the etiology of postmenopausal changes.

A materials testing 2.0 framework for identifying creep parameters from full-field strain measurements of a notched specimen

open access: yesMaterials & Design
The Materials Testing 2.0 (MT2.0) paradigm offers a promising alternative to conventional uniaxial testing by identifying constitutive parameters from a single heterogeneous test.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Choosing an Exchange Rate Regime [PDF]

open access: yes
Choosing an exchange rate regime is one of the most important decisions in macroeconomic policymaking. Some countries may peg their currency to gain credibility and control domestic inflation, while others may be more prone to float due to the larger ...

Physiological Trade-Offs Under Thermal Variability in the Giant Lion’s Paw Scallop (Nodipecten subnodosus): Metabolic Compensation and Oxidative Stress

open access: yesStresses
Understanding how thermal variability affects marine ectotherms is essential for predicting species resilience under climate change. We investigated the physiological responses of juvenile Nodipecten subnodosus (lion’s paw scallop), offspring of two ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

A two regime model of inflation and unemployment fluctuations [PDF]

open access: yes
In this paper we present a formal definition of the notions of economic regime and regime dynamics. Starting from these definitions, we discuss a multiple regime dynamic model generating an endogenous unemployment-price adjustment mechanism.
