Unveiling the susceptibility of nanosecond pulsed electric field on intracellular function in breast cancerous and normal cells using fluorescence imaging.

Modulation in cellular function and cell death through electrostimulation of intracellular organelles with the application of 50 ns pulsed electric field (nsPEF) have been investigated in breast cancerous MCF7 and normal MCF10A cells by developing a three-dimensional microelectrode device integrated with a fluorescence microscope. The findings revealed that nsPEF induced distinct effects on intracellular functions and dynamics in MCF7 and MCF10A cells. MCF10A cells exhibited significantly higher survivability than MCF7 cells, with different modes of cell death observed between them.

Heat-Killed subsp. 557 Extracts Protect Chondrocytes from Osteoarthritis Damage by Reducing Inflammation: An In Vitro Study.

Background: Osteoarthritis (OA) is a chronic condition characterized by joint pain and disability, driven by excessive oxidative stress and inflammatory cytokine production in chondrocytes, resulting in cell death and cartilage matrix breakdown. Our previous study showed that in monosodium iodoacetate (MIA)-induced OA rats, oral administration of heat-killed subsp. 557 (LDL557) could significantly decrease OA progression.

Diabetic Nephropathy-Associated Impaired Aortic Function Is Not Mediated by Mean Arterial Pressure and Its Determinants.

The study aimed to assess the potential impacts of mean arterial pressure (MAP) and its determinants (cardiac output and systemic vascular resistance) on diabetic nephropathy (DNP)-associated impaired aortic function. This multi-ethnic study included 115 chronic kidney disease (CKD) patients (67 non-dialysis and 48 dialysis). Six aortic function measures were evaluated by SpygmoCor.

Intrinsic Repeated Self-Healing Textiles: Developing Electrospun Fabrics for Enhanced Durability and Stretchability.

The development of healable polymers represents a significant advancement in materials science, addressing the need for sustainable solutions that can reduce waste and prolong the lifespan of various products. For the development of healable polymer fabrics, however, there are still unsolved issues because of limited healing cycles and poor mechanical properties. In this work, we present intrinsically healable materials for the creation of stretchable, healable fabrics.

Feruloylacetone and Its Analog Demethoxyferuloylacetone Mitigate Obesity-Related Muscle Atrophy and Insulin Resistance in Mice.

Obesity-induced muscle alterations, such as inflammation, metabolic dysregulation, and myosteatosis, lead to a decline in muscle mass and function, often resulting in sarcopenic obesity. Currently, there are no definitive treatments for sarcopenic obesity beyond lifestyle changes and dietary supplementation. Feruloylacetone (FER), a thermal degradation product of curcumin, and its analog demethoxyferuloylacetone (DFER), derived from the thermal degradation of bisdemethoxycurcumin, have shown potential antiobesity effects in previous studies.
