A breast pump is a mechanical device that lactating women use to extract milk from their breasts. They may be manual devices powered by hand or foot movements or automatic devices powered by electricity. Breast pumps come in several varieties to suit different needs of mothers.
Breastfeeding difficulties refers to problems that arise from breastfeeding, the feeding of an infant or young child with milk from a woman's breasts.Although babies have a sucking reflex that enables them to suck and swallow milk, and human breast milk is usually the best source of nourishment for human infants, [1] there are circumstances under which breastfeeding can be problematic, or even ...
Ruggeri et al. have recently developed off-resonance, low power and short pulse AFM-IR (ORS-nanoIR) to prove the acquisition of infrared absorption spectra and chemical maps at the single molecule level, in the case of macromolecular assemblies [17] [22] [21] and large protein molecules with a spatial resolution of ca. 10 nm.

Femtosecond up-conversion is a pump-probe technique that uses nonlinear optics to combine the fluorescence signal and probe signal to create a signal with a new frequency via photon upconversion, which is subsequently detected. The probe scans through delay times after the pump excites the sample, generating a plot of intensity over time. [16]
The near-infrared spectra of very young stars provide important information about their ages and masses, which is important for understanding star formation in general. Astronomical spectrographs have also been developed for the detection of exoplanets using the Doppler shift of the parent star due to the radial velocity of the planet around ...
Breast right after surgical intervention for breast abscess. A breast abscess is a collection of pus that develops in the breast with various causes. [14] During lactation, breast abscess develops only rarely, most sources cite about 0.4–0.5% of breastfeeding women. [8] Known risk factors are age over 30, primiparous (first birth) and late ...
Breast engorgement occurs in the mammary glands due to expansion and pressure exerted by the synthesis and storage of breast milk. It is also a main factor in altering the ability of the infant to latch-on. Engorgement changes the shape and curvature of the nipple region by making the breast inflexible, flat, hard, and swollen.
Nanophotonics has also been implicated in aiding the controlled and on-demand release of anti-cancer therapeutics like adriamycin from nanoporous optical antennas to target triple-negative breast cancer and mitigate exocytosis anti-cancer drug resistance mechanisms and therefore circumvent toxicity to normal systemic tissues and cells.
