Using callus culture to study the drought tolerance of wheat genotypes [PDF]

open access: yesSelekcija i Semenarstvo, 2000
In this paper, we studied the drought tolerance under in vitro conditions of two winter wheat (T. aestivum L.) cultivars, Košuta and Renesansa. The tolerance was tested on a modified MS (Murashige and Skoog, 1962) nutrient medium to which polyethylene ...

Preimplantation embryo programming: transcription, epigenetics, and culture environment

open access: yes, 2008
International audiencePreimplantation development directs the formation of an implantation- or attachment-competent embryo so that metabolic interactions with the uterus can occur, pregnancy can be initiated, and fetal development can be sustained.

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

open access: yesAdvanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Investigation into the Effects of Oxidative Stress on Reproductive Development.

open access: yes, 2007
Nuclear transfer (NT), or cloning, which is the transfer of a donor nucleus to a recipient enucleated oocyte, has been successfully achieved to produce viable offspring in many species.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

open access: yesAdvanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Mechanoluminescent HOF Nanotransducers Enabled Sono‐Optogenetics in Parkinsonian Rats

open access: yesAdvanced Functional Materials, EarlyView.
We present a mechanoluminescent system utilizing porous hydrogen‐bonded organic frameworks (HOFs) as a toolkit for focused ultrasound‐triggered, non‐invasive light delivery to the deep brain in rats. This approach enables the specific activation of PV‐GPe neurons in dopamine‐depleted Parkinson's disease rat models, resulting in a comparable alleviation

Histology of embryoid development in oil palm (Elaeis guineensis Jacq.) cell suspension culture [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2001
Embryos of oil palm (Elaeis guineensis Jacq.) variety tenera were cultured on Eeuwens or Y3 (1976; 1978) medium supplemented with 2 mg/l 2,4-D. Calluses were initiated from these embryos.

Multifunctional Gold Nanocluster‐Based PROTAC System for Targeted Degradation of Phosphorylated Tau and Modulation of Neuroinflammation in Alzheimer's Disease

open access: yesAdvanced Functional Materials, EarlyView.
We present a novel proteolysis‐targeting chimera (PROTAC) system conjugated to lipoic acid gold nanoclusters (PLANC), designed to degrade pTau, regulate inflammatory signaling, and effectively traverse the blood‐brain barrier (BBB). PLANC degraded pTau at various phosphorylation sites, with mechanistic studies confirming proteasome‐mediated degradation

Tolerance of wheat genotypes to lead in in vitro culture [PDF]

open access: yesSelekcija i Semenarstvo, 2000
We studied the effects of five lead concentrations (10-7, 10-6, 10-5, 10-4 and 10-3 M) on callus growth and dry matter content in the callus tissue. Two winter wheat (Triticum aestivum L.) cultivars, Balkan and Proteinka, were used to isolate mature ...
