Thermo-acoustofluidics: composition-based separation of vesicles

Extracellular vesicles (EVs) are membrane-enclosed entities actively released from cells into almost all types of bodily fluids such as blood and urine. Exosomes, i.e. small EVs with 40-100 nm in diameter, are particularly important since they serve

How rising minority income does (or does not) lead to residential integration in the US

This paper examines how access to integrated neighborhoods changed for Asians, Hispanics, and African Americans from 1970 to 2010. Data come from the Decennial U.S. Census, with neighborhoods defined using census tracts, which are small geographic units

The evolutionarily conserved role of Sp1 in appendage morphogenesis

Despite millions of years of independent evolution, some aspects of vertebrate and arthropod development share striking similarities. For example the appendages of a mouse and of a fly, at the naked eye doesn’t seem to share too

Temporo-mandibular dysfunctions and injections

Temporo-mandibular joint (TMJ) dysfunction is a recurrent pathology and classical treatment only relieves some patients. Botulinum Toxin type A (BoNTA) injections, both intra-muscular and intra-articular, and intra-articular injections of sodium hyaluronate or hyaluronic acid (HA) are precious

The effect of motherhood and work on women’s time pressure

Deadlines, time pressure, stress, and hustle: Who has not experienced the mad rush of a hectic day? Time pressure ─ also referred to as time crunch, time squeeze, or time deprivation ─ is a widespread phenomenon in

Host factors, the “Simon Says” for microbial biofilms

Microbes change their behavior, i.e., phenotype, in response to environmental clues. Since microbes, e.g. normal flora and pathogens evolved with their respective hosts, being able to recognize host-derived chemical signals provides a distinctive advantage. This is particularly

Arabidopsis ACYL-COA-BINDING PROTEIN6: a lipid-binding protein in the phloem

Plants utilize long-distance transport systems via their vascular tissues. The xylem is used for water and mineral transport, while the phloem translocates various macromolecules. Although lipids have been detected in the phloem sap, their movement is not

Stolen innocence: the rapes of little girls during Jim Crow

During the period of legally sanctioned segregation in the U.S., known as the Jim Crow era(roughly 1865 to 1965), the public discussion of “rape” focused on assaults of white women. However, a much more common problem was

Design and build your own integrated microfluidic systems using magnetic interconnects

Microfluidic technology involves the miniaturization and integration of complex systems that enable low volumes (microliters, μL; 1 μL = 1×10-6 liter, L) of fluids to be manipulated and controlled in micron-sized (1 micron/micrometer, μm = 0.001 mm)

International consensus on definition and management of postoperative ileus

Postoperative ileus (POI) refers to a pathologic pattern of gastrointestinal motility occurring after any type of major surgery. It prevents sufficient food intake, causes abdominal discomfort and increases the length of stay. It also imposes a significant

New coordination between F-actin and microtubules

Cells maintain vesicles transportation, cell migration, cell polarity, mitosis, cell shape and even cell signaling through cytoskeleton, which is the most conservative and essential structures in diverse organism. F-actin and microtubule, two components of the cytoskeleton, have

Memory process in patients with ischemic left ventricular dysfunction

Heart failure is a complex syndrome characterized by hemodynamic and neuro-hormonal alterations. In recent literature a relationship between heart failure and the presence of cognitive disorders, in particular in the domain of the attentional-executive functions, was reported

Alkene synthesis – any way you want it

An alkene is a molecule containing two carbon atoms connected by a double bond, C=C (Fig. 1A). Alkenes are very common but their proper preparation requires careful attention to the placement of the four groups (Ri, i

Getting health allies from agriculture enemies

In recent years, research in nanotechnologies has demonstrated that nanometer-sized particles constructed using a wide array of materials (e.g. metals, lipids, polymers, proteins) can offer answers to unmet questions concerning drug/vaccine delivery. Ideally, these systems should prevent

Can environmental factors influence amphibian’s skin bacterial shield?

Amphibians are particularly vulnerable to environmental perturbations. Its ecology and life cycle potentiates its exposure to aquatic and terrestrial pressures and its naked skin provides free flow of water and other substances across it. However, amphibian’s skin

The mind and mouth of a predatory worm

Nematodes (roundworms) are some of the most abundant and successful animals on the planet and are found in nearly every environment capable of supporting life. In order to exploit these hugely diverse habitats, different nematode species have
