High-Throughput 96-Well Nanogroove-Enhanced Electrical Impedance Biosensor for Real-Time Label-Free Cancer Drug Screening.

This study advances bioelectronic platforms and cellular behavior analysis by enhancing the precision and scalability of nanopatterned membranes integrated with electrode arrays for real-time, high-throughput monitoring. By employing self-assembled monolayers (SAMs) and optimizing imprinting parameters, uniform large-area nanopatterns are successfully fabricated, overcoming challenges such as the "rabbit ears" effect and inconsistent pattern fidelity. The nanopatterned substrates, integrated within 96-well plates with electrode arrays, enable real-time impedance spectroscopy, providing a dynamic assessment of cellular behavior under chemotherapeutic drug exposure.

Regenerative Strategy of Gold Electrodes for Long-Term Reuse of Electrochemical Biosensors.

Gold is of considerable interest for electrochemical active surfaces because thiol-modified chemicals and biomolecules can be easily immobilized with a simple procedure. However, most gold surfaces are damaged with repetitive measurements, so they are difficult to reuse. Here we demonstrate a novel electrochemical cleaning method of gold surfaces to reuse electrodes with a simple protocol that is easy and nontoxic.

FERONIA Confers Resistance to Photooxidative Stress in Arabidopsis.

Plants absorb light energy required for photosynthesis, but excess light can damage plant cells. To protect themselves, plants have developed diverse signaling pathways which are activated under high-intensity light. Plant photoprotection mechanisms have been mainly investigated under conditions of extremely high amount of light; thus, it is largely unknown how plants manage photooxidative damage under moderate light intensities.

Endoplasmic Reticulum (ER) Stress Inhibitor or Antioxidant Treatments during Micromanipulation Can Inhibit Both ER and Oxidative Stresses in Porcine SCNT Embryos.

We investigated the effects of endoplasmic reticulum (ER) stress inhibitor and antioxidant treatments during the micromanipulation of somatic cell nuclear transfer (SCNT) on development of SCNT embryos. Tauroursodeoxycholic acid (TUDCA), an ER stress inhibitor and vitamin C (Vit. C), an antioxidant, were treated by alone or in combination, then, the level of X-box binding protein 1 () splicing and the expressions of ER stress-associated genes, oxidative stress-related genes, and apoptotic genes were confirmed in the 1-cell and blastocyst stages.

Reinforcement Learning for Energy Optimization with 5G Communications in Vehicular Social Networks.

Increased data traffic resulting from the increase in the deployment of connected vehicles has become relevant in vehicular social networks (VSNs). To provide efficient communication between connected vehicles, researchers have studied device-to-device (D2D) communication. D2D communication not only reduces the energy consumption and loads of the system but also increases the system capacity by reusing cellular resources.

The Influence of Tourists' Experience of Quality of Street Foods on Destination's Image, Life Satisfaction, and Word of Mouth: The Moderating Impact of Food Neophobia.

Due to growing food-related tourism, there is increasing interest about street foods worldwide, including South Korea. Many types of food-related experiences have been considered as one of the significant elements to develop positive perceptions about a destination, and street food has been recognized as a critical clue for encouraging tourists to a destination. Previous scholars mentioned street food as a public health risk element as well as a significant factor to attract tourists' attention.

Effects of Endoplasmic Reticulum Stress Inhibitor Treatment during the Micromanipulation of Somatic Cell Nuclear Transfer in Porcine Oocytes.

We examined the effects of endoplasmic reticulum (ER) stress inhibitor treatment during the micromanipulation of porcine somatic cell nuclear transfer (SCNT) on the development of SCNT embryos. ER stress inhibitors such as salubrinal (200 nM) and tauroursodeoxycholic acid (TUDCA; 100 μM) were added to the micromanipulation medium and holding medium. The expression of X-box binding protein 1 (), ER-stress-associated genes, and apoptotic genes in SCNT embryos was confirmed at the one-cell and blastocyst stages.

Effect of Endoplasmic Reticulum (ER) Stress Inhibitor Treatment during Parthenogenetic Activation on the Apoptosis and Development of Parthenogenetic Porcine Embryos.

We investigate the effect of endoplasmic reticulum (ER) stress inhibitor treatment during parthenogenetic activation of oocytes on the ER stress generation, apoptosis, and development of parthenogenetic porcine embryos. Porcine matured oocytes were activated by 1) electric stimulus (E) or 2) E+10 μM Ca-ionophore (A23187) treatment (EC). Oocytes were then treated by ER stress inhibitors such as salubrinal (200 nM) and tauroursodeoxychloic acid (TUDCA, 100 μM) for 3 h prior to culture.

Energy-Effective Power Control Algorithm with Mobility Prediction for 5G Heterogeneous Cloud Radio Access Network.

In 5G networks, heterogeneous cloud radio access network (H-CRAN) is considered a promising future architecture to minimize energy consumption and efficiently allocate resources. However, with the increase in the number of users, studies are performed to overcome the energy consumption problems. In this study, we propose a power control algorithm with mobility prediction to provide a high-energy efficiency for 5G H-CRAN.

Engineered Tumor-Targeted T Cells Mediate Enhanced Anti-Tumor Efficacy Both Directly and through Activation of the Endogenous Immune System.

Chimeric antigen receptor (CAR) T cell therapy has proven clinically beneficial against B cell acute lymphoblastic leukemia and non-Hodgkin's lymphoma. However, suboptimal clinical outcomes have been associated with decreased expansion and persistence of adoptively transferred CAR T cells, antigen-negative relapses, and impairment by an immunosuppressive tumor microenvironment. Improvements in CAR T cell design are required to enhance clinical efficacy, as well as broaden the applicability of this technology.

Effect of graphene on growth of neuroblastoma cells.

The unique properties of graphene have earned much interest in the fields of materials science and condensed-matter physics in recent years. However, the biological applications of graphene remain largely unexplored. In this study, we investigated the conditions and viability of a cell culture exposed to graphene onto glass and SiO2/Si, using a human nerve cell line, SH-SY5Y.
