Published: May 2011

In this paper, we report the synthesis, characterization and Fe(3+)-sensing properties of a series of new artificial fluorescent molecular clips, and structure of clip 1 is confirmed by X-ray crystallography. All these molecular clips had the ability to bind and sense Fe(3+) selectively through decrease fluorescence responses in THF-MeOH-Water. Fluorimetric titration experiment indicated that the quenching of these compounds' fluorescence upon Fe(3+) probably arises from the electron/energy transfer between Fe(3+) and the excited chemosensors. The limit of detection, linear concentration range and selectivity of the fluorescent molecular clips were evaluated in this study as well.

Hidradenitis suppurativa is a chronic inflammatory disease characterised by painful, deep-seated nodules, abscesses, and draining tunnels in the skin of axillary, inguinal, genitoanal, or inframammary areas. In recent years, the body of knowledge in hidradenitis suppurativa has advanced greatly. This disorder typically starts in the second or third decade of life.

Background And Aims: Computer-aided detection software (CADe) has shown promising results in real-time polyp detection, but a limited head-to-head comparison of the available CADe systems has been performed. Moreover, such systems have not been compared to endoscopists using standardized videos. This study aims to compare the performance of three CADe systems in detecting polyps, employing a novel standardized methodology.

Cryo-electron tomography (cryo-ET) is confronted with the intricate task of unveiling novel structures. General class discovery (GCD) seeks to identify new classes by learning a model that can pseudo-label unannotated (novel) instances solely using supervision from labeled (base) classes. While 2D GCD for image data has made strides, its 3D counterpart remains unexplored.

Nose-clip use in semi-free ranging pigs reduces rooting without disrupting affiliative behaviour or causing prolonged stress.

Domestic pigs (Sus scrofa) raised under natural conditions can show their complete behavioural repertoire. However, rooting behaviour can have a great impact on the environment. In the context of the promotion of farm animal welfare and environmental concerns, this study investigated the potential of nose-clips as a less invasive alternative to nose-rings for the management of rooting behaviour of free-ranging pigs.
