Objective: Pregnancy in cattle after embryo transfer (ET) is influenced by several factors, including embryo quality. Therefore, preparing high-quality embryos with the greatest developmental potential is essential for achieving a successful pregnancy after ET. Meanwhile, blastocysts produced by in vitro fertilization (IVF) procedure have different developmental speed during in vitro culture (IVC) and they exhibited different competence in the establishment of pregnancy.

The Warburg effect, which describes the fermentation of glucose to lactate even in the presence of oxygen, is ubiquitous in proliferative mammalian cells, including cancer cells, but poses challenges for biopharmaceutical production as lactate accumulation inhibits cell growth and protein production. Previous efforts to eliminate lactate production in cells for bioprocessing have failed as lactate dehydrogenase is essential for cell growth. Here, we effectively eliminate lactate production in Chinese hamster ovary and in the human embryonic kidney cell line HEK293 by simultaneous knockout of lactate dehydrogenases and pyruvate dehydrogenase kinases, thereby removing a negative feedback loop that typically inhibits pyruvate conversion to acetyl-CoA.

Previous studies showed no improvement in bacterial biomass for Puniceispirillum marinum IMCC1322 under light regimes. Nevertheless, in nutrient-replete cultures with higher inoculating cell densities, strain IMCC1322 exhibited proteorhodopsin photoheterotrophy. Increasing both inoculum size and the amino acid pool can eliminate quorum sensing and starvation responses in strain IMCC1322.

Process intensification and simplification in biopharmaceutical manufacturing have driven the exploration of advanced feeding strategies to improve culture performance and process consistency. Conventional media design strategies, however, are often constrained by the stability and solubility challenges of amino acids, particularly in large-scale applications. As a result, dipeptides have emerged as promising alternatives.

Disrupting the interaction between matrix metalloproteinase-7 (MMP-7) and syndecan-2 (SDC-2) can yield anticancer effects in colon cancer cells. Here, a single-chain variable fragment (scFv) targeting the pro-domain of MMP-7 was generated as a potential candidate anticancer agent. Among the generated scFvs, those designated 1B7 and 1C3 showed the strongest abilities to inhibit the ability of MMP-7 pro-domain to directly interact with SDC-2 in vitro and decrease the cancer activities of human HT29 colon adenocarcinoma cells.

Current in vitro models of 3D tumor spheroids within the microenvironment have emerged as promising tools for understanding tumor progression and potential drug responses. However, creating spheroids with functional vasculature remains challenging in a controlled and high-throughput manner. Herein, a novel open 3D-microarray platform is presented for a spheroid-endothelium interaction (ODSEI) chip, capable of arraying more than 1000 spheroids on top of the vasculature, compartmentalized for single spheroid-level analysis of drug resistance, and allows for the extraction of specific spheroids for further analysis.

We investigated the dynamics of communicative initiation in infant-caregiver interactions across ages and language abilities. Analyses of 228 Language ENvironment Analysis (LENA) recordings from 141 Korean adult-child dyads (60 girls; aged 7-30 months) replicated the initiator effect reported in North American populations. This effect, demonstrated by longer utterances, more frequent speech, and shorter response times in self-initiated interactions for both children and adults, suggests potential cross-cultural consistency in this conversational dynamic and remained consistent across ages in most conversational measures.

Skin-on-a-chip models provide physiologically relevant platforms for studying diseases and drug evaluation, replicating the native skin structures and functions more accurately than traditional 2D or simple 3D cultures. However, challenges remain in creating models suitable for microneedling applications and monitoring, as well as developing skin cancer models for analysis and targeted therapy. Here, we developed a human skin/skin cancer-on-a-chip platform within a microfluidic device using bioprinting/bioengineering techniques.

βPix is a guanine nucleotide exchange factor for the Rac1 and Cdc42 small GTPases, which play important roles in dendritic spine morphogenesis by modulating actin cytoskeleton organization. The formation and plasticity of the dendritic spines are essential for normal brain function. Among the alternatively spliced βPix isoforms, βPix-b and βPix-d are expressed specifically in neurons.

This study presents a novel in vitro bilayer 3D co-culture platform designed to obtain cancer-associated fibroblasts (CAFs)-like cells. The platform consists of a bilayer hydrogel structure with a collagen/polyethylene glycol (PEG) hydrogel for fibroblasts as the upper layer and an alginate hydrogel for tumor cells as the lower layer. The platform enabled paracrine interactions between fibroblasts and cancer cells, which allowed for selective retrieval of activated fibroblasts through collagenase treatment for further study.

Background: Among the people with diverse backgrounds and cultural customs living in Japan, two important groups, namely, war-displaced Japanese returning from China and South and North Korean nationals who are naturalized citizens residing in Japan, will experience population aging in the same way as the general Japanese population. In old age, physical function generally declines, multiple diseases are more likely to occur, and health issues that need to be addressed increase in number. The aim of this study was to identify the factors associated with the use of preventive health services in Japan by older Korean residents and war-displaced Japanese returning from China.

Bloodstream bacterial infections, a major health concern due to rising sepsis rates, require prompt, cost-effective diagnostics. Conventional methods, like CO-based transduction, face challenges such as volatile metabolites, delayed gas-phase signaling, and the need for additional instruments, whereas electrochemical sensors provide rapid, sensitive, and efficient real-time detection. In this study, we developed a bioreceptor-free Prussian blue (PB) sensor platform for real-time bacterial growth monitoring in blood culture.

3D bioprinting is an advanced manufacturing technique that involves the precise layer-by-layer deposition of biomaterials, such as cells, growth factors, and biomimetic scaffolds, to create three-dimensional living structures. It essentially combines the complexity of biology with the principles of 3D printing, making it possible to fabricate complex biological structures with extreme control and accuracy. This review discusses how 3D bioprinting is developing as an essential step in the creation of alternative food such as cultured meat and seafood.

Protocatechuate acid (PCA) is a phenolic acid naturally synthesized by various organisms. Protocatechuic acid is synthesized by plants for physiological, metabolic functions, and self-defense, but extraction from plants is less efficient compared to the microbial culture process. The microbial synthesis of protocatechuic acid is sustainable and, due to its high yield, can save energy consumption when producing the same amount.

Cultured meat (CM) is derived from the in vitro myogenesis of muscle satellite (stem) cells (MSCs) and offers a promising alternative protein source. However, the development of a cost-effective media formulation that promotes cell growth has yet to be achieved. In this study, laxogenin (LAX) and 5-alpha-hydroxy-laxogenin (5HLAX) were computationally screened against myostatin (MSTN), a negative regulator of muscle mass, because of their antioxidant properties and dual roles as MSTN inhibitors and enhancers of myogenesis regulatory factors.
