Non-invasive imaging through scattering medium and around corners beyond 3D memory effect.

The three-dimensional (3D) memory effect (ME) has been shown to exist in a variety of scattering scenes. Limited by the scope of ME, speckle correlation technology only can be applied in a small imaging field of view (FOV) with a small depth of field (DOF). In this Letter, an untrained neural network is constructed and used as an optimization tool to restore the targets beyond the 3D ME range.

Association of gestational anemia with pregnancy conditions and outcomes: A nested case-control study.

Background: Gestational anemia is a serious public health problem that affects pregnant women worldwide. Pregnancy conditions and outcomes might be associated with the presence of gestational anemia. This study investigated the association of pregnancy characteristics with anemia, exploring the potential etiology of the disease.

Expression of transforming growth factor-β in mast cells in human chronic periapical diseases.

This study was undertaken to investigate the distribution of mast cells (MCs) and the expression of transforming growth factor-β (TGF-β) on tryptase positive MCs in different types of human periapical diseases. Periapical tissues of 78 participates were used in this study, including healthy control (n=28), periapical cyst (n=25), and periapical granuloma (n=25). The tissue samples were fixed in 10% formalin for at least 48 h, followed by staining with hematoxylin and eosin (HE) for histopathological examination.
