We have developed a direct mask modification method applicable in hole-mask nanostructure fabrication. It is demonstrated that by using this technique the size, material, relative location and ordering of individual subunits can be controlled and varied independently to generate hetero-assemblies of nanostructures including chiral structures over large areas.

In recent years, pelvic floor surgeons have increasingly repaired pelvic organ prolapse around an intact uterus. Uterine conservation and hysteropexy have been driven by patient preference, less risk of mesh erosion, shorter operative time, and decreased blood loss and postoperative pain. We present a case series of patients with cervical ...

Narcolepsy (NA) is a sleep disorder characterized by excessive daytime sleepiness and an increased propensity of rapid eye movement sleep. If left untreated, NA can lead to academic underachievement or job loss because of dozing off or mistakes caused by inattentiveness due to sleepiness. Although untreated narcolepsy patients may suffer ...

Proteins from higher fungi have attracted interest because of their exceptional characteristics. Macrocypins, cysteine protease inhibitors from the parasol mushroom Macrolepiota procera, were evaluated for their adverse effects and their mode of action on the major potato pest Colorado potato beetle (CPB, Leptinotarsa decemlineata Say). They were shown to reduce ...

When people are confronted with social dilemmas, their decision-making strategies tend to be associated with individual social preferences; prosocials have an intrinsic willingness to cooperate, while proselfs need extrinsic motivators signaling personal gain. In this study, the biological roots for the proselfs/prosocials concept are explored by investigating the neural correlates ...

Human oxoguanine glycosylase 1 (hOGG1) is an important part in the base excision repair (BER) pathway of DNA repair. Numerous epidemiological studies were published to assess the association between hOGG1 C8069G polymorphism and risk of colorectal cancer, but they reported contradictory results. A meta-analysis was performed to clarify the effect ...

Autophagy is a bulk degradation system induced by cellular stresses such as nutrient starvation. Its function relies on the formation of double-membrane vesicles called autophagosomes. Unlike other organelles that appear to stably exist in the cell, autophagosomes are formed on demand, and once their formation is initiated, it proceeds surprisingly ...
