This is an investigation into the exact forms of images point charges in 2D conducting ellipses and 3D prolate spheroids. For ellipse with exterior source, we compare two previous expressions for analytic continuation inside down to focal line, location image charge. interior discover a sequence lying outside. source close surface spheroid, series solutions potential diverge region that encompa...

Purpose Axonal severing is critical to the irreversible disability that occurs over the course of multiple sclerosis (MS). Reactive oxygen species (ROS) are implicated in neurodegenerative aspects of MS: axonal spheroid formation, severing, and axoplasmic Ca elevation. However, the exact role of Ca in spheroid formation remains unclear. The mechanism of action of natural anti-oxidants such as l...

A Sessile Drop Method for 3D Cell Spheroid Culture In article number 2100972, Bangyong Sun, Gang Li, and co-workers demonstrate a sessile drop platform long-term spheroid culture. Benefitting from its open, upward, non-wettable features, the provides not only high mechanical stability easiness of medium exchange but also excellent antifouling ability oxygen availability, thus enabling robust cu...

An attractive option for tissue engineering is to use of multicellular spheroids as microtissues, particularly with stem cell spheroids. Conventional approaches of fabricating spheroids suffer from low throughput and polydispersity in size, and fail to supplement cues from extracellular matrix (ECM) for enhanced differentiation. In this study, we report the application of microfluidics-generate...

Balloon pumps are employed to assist cardiac function in cases of acute myocardial infarction, ventricular arrhythmias, cardiogenic shock, unstable angina, refractory failure, or surgery. Counterpulsation, through increasing the diastolic pressure and reducing systolic pressure, increases coronary perfusion assists heart pump more blood at each contraction. An expanding-contracting balloon, mod...

Isolated stromal cells from the ampullary and isthmic parts of bovine oviductal tissues were cultured in monolayer and spheroid (cell aggregate) systems. Prostaglandin F2α (PGF) plays a crucial role in oviductal contraction and is produced by oviductal epithelial cells in cattle. Since stromal cells of many organs produce PGF, PGF production by bovine oviductal stromal cells was investigated. A...

The electromagnetic fields scattered when a plane wave is incident on an oblate spheroid in the side-on orientation may be calculated using a generalization of Mie theory, and the results may be decomposed in a Debye series expansion. A number of optical caustics are observed in the computed scattered intensity for the one internal reflection portion of the Debye series for scattering angles in...

Redshift evolution of supermassive black hole mass functions (BHMFs) is investigated up to z ∼ 1. BHMFs at intermediate redshifts are calculated in two ways. One way is from early-type galaxy luminosity functions (LFs); we assume an MBH − Lsph correlation at a redshift by considering a passive evolution of Lsph in the local relationship. The resultant BHMFs (spheroid-BHMFs) from LFs of red sequ...

Using the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope, we have obtained deep optical images reaching stars well below the oldest main sequence turnoff in three fields of the Andromeda Galaxy: the spheroid, tidal stream, and outer disk. These observations allow a complete reconstruction of the star formation history in these fields. We analyze the color-magnitude diagrams of ...

OBJECTIVE Gastric cancer (GC) is widely associated with chronic inflammation. The pro inflammatory microenvironment provides conditions that disrupt stem/progenitor cell proliferation and differentiation. The signal transducer and activator of transcrip- tion-3 (STAT3) signaling pathway is involved in inflammation and also contributes to the maintenance of embryonic stem cell (ESCs) pluripotenc...
