The combined effects of copper and zinc on Arabidopsis involve differential regulation of chlorophyll synthesis and photosystem function.

Copper (Cu) and zinc (Zn) are both oxidation-reducing metal elements that are necessary for plant growth, and their effect often depends on their concentration. However, there are few studies that have investigated how plants are stressed and affected when the two ions are present simultaneously, especially when one ion is beneficial due to a low concentration and the other is detrimental due to a high concentration. To address this question, we treated Arabidopsis plants with either high or/and low concentrations of the two ions and investigated their mutual effects and the underlying molecular mechanism, focusing on photosynthetic function.

A DFT approach to correlate the physical characteristics of novel chalcopyrites ASbN(A = Li, Na) for green technology.

Semiconductor chalcopyrite compounds have been a subject of research interest due to their diverse range of physical properties that have captured the attention of scientists. In this ongoing research, we have examined the physical characteristics of LiSbN and NaSbN chalcopyrites using DFT. The modified Becke-Johnson (mBJ) potential is utilized for the computation of electronic structures.

Auxin homeostasis in plant responses to heavy metal stress.

Expeditious industrialization and anthropogenic activities have resulted in large amounts of heavy metals (HMs) being released into the environment. These HMs affect crop yields and directly threaten global food security. Therefore, significant efforts have been made to control the toxic effects of HMs on crops.

ROS Homeostasis Involved in Dose-Dependent Responses of Seedlings to Copper Toxicity.

As an essential element in plant nutrition, copper (Cu) can promote or inhibit plant growth depending on its concentration. However, the dose-dependent effects of copper, particularly on DNA damage associated with reactive oxygen species (ROS) homeostasis, are much less understood. In this work, we analyzed the dual effect of Cu (5, 20, and 60 μM) on the reproductive performance of Arabidopsis plants.

DIgestive COmplications in DIabetes - the DICODI population study.

Background: Diabetes type 1 and type 2 may develop gastrointestinal complications e.g., gastroparesis and gastroenteropathy.

Effect of overexpression of inhibin alpha (1-32) fragment on bovine granulosa cell proliferation, apoptosis, steroidogenesis, and development of co-cultured oocytes.

The objective was to determine the effects of an inhibin alpha (1-32) fragment gene on proliferation, apoptosis, and steroidogenesis of bovine granulosa cells (GC) isolated from medium and small follicles (diameter >4-8 and 1-4mm, respectively), and the effect of GC, previously transfected with pEGISI, on oocyte maturation and in vitro embryo development. To enhance expression of the inhibin alpha (1-32) fragment, GC were transfected with pEGISI. Transfection inhibited (P<0.
