Residual Nitrite, Nitrate, and Volatile N-Nitrosamines in Organic and Conventional Ham and Salami Products.

Nitrite and nitrate in meat products may be perceived negatively by consumers. These compounds can react to form carcinogenic volatile N-nitrosamines. "Nitrite-free" (i.

Stiffness-tunable velvet worm-inspired soft adhesive robot.

Considering the characteristics and operating environment of remotely controlled miniature soft robots, achieving delicate adhesion control over various target surfaces is a substantial challenge. In particular, the ability to delicately grasp wrinkled and soft biological and nonbiological surfaces with low preload without causing damage is essential. The proposed adhesive robotic system, inspired by the secretions from a velvet worm, uses a structured magnetorheological material that exhibits precise adhesion control with stability and repeatability by the rapid stiffness change controlled by an external magnetic field.

An inducible model for medial calcification based on matrix Gla protein deficiency.

Calcific deposits in the arterial media have been associated with a number of metabolic and genetic disorders including diabetes, chronic kidney disease and generalized arterial calcification of infancy. The loss of matrix Gla protein (MGP) leads to medial elastic lamina calcification (elastocalcinosis) in both humans and animal models. While MGP-deficient (Mgp) mice have been used as a reliable model to study medial elastocalcinosis, these mice are difficult to maintain because of their fragility.

Thyroid ima artery (the artery of Neubauer) - how much do we know?

Blood supply of the thyroid gland was the subject of numerous original studies, case reports and meta-analysies. The number of surgical procedures carried out on the thyroid gland significantly increases during last few decades. The cadaveric report discusses the case of a thryoidea ima artery (TIA) which originated from the brachiocephalic artery before its terminal subdivision, giving off numerous branches to the infrahyoid muscles, trachea and thyroid gland.

Solvent Attenuation of London Dispersion in Polycyclic Aromatic Stacking.

Solvent competition for London dispersion attenuates its energetic significance in molecular recognition processes. By varying both the stacked contact area and the solvent, here we experimentally deconvolute solvent attenuation using molecular balances. Experimental stacking energies (phenyl to pyrene) correlated strongly with calculations only when dispersion was considered.
