Virtual reality teaching in chemotherapy administration: Randomised controlled trial.

Aims And Objectives: This study examined the effect of virtual reality (VR)-based documents (VRdocs) on knowledge and attitude towards chemotherapy administration in nursing students.

Background: Chemotherapeutic drugs in cancer patients are a complicated and dangerous process. However, despite the high toxicity of the chemotherapeutic drugs, the compulsory or internship courses in nursing schools do not include training in operational chemotherapeutics and its associated safety measures.

Red LED light treatment promotes cognitive learning through up-regulation of trpm4 in zebrafish.

Although light emitting diodes (LEDs) are widely used in our daily lives, there is little research regarding LED light's possible effects on biological functions. We used a zebrafish animal model to investigate the long-term effects of white, blue and red LED lights on cognitive learning and memory recall. Our data suggest that these treatments had not only an impact on learning but also surprisingly long-lasting effects, particularly with regard to individuals treated with red light.

Fabrication of Hydrophilic Surface on Rigid Gas Permeable Contact Lenses to Enhance the Wettability Using Ultraviolet Laser System.

The widely used rigid gas permeable (RGP) contact lenses provide higher oxygen permeability and tear exchange rate than do soft contact lenses. However, their wettability warrants improvement to enhance the wearing comfort. This study used UV laser (wavelength = 355 nm) to modify the surface properties of RGP contact lenses with materials of Boston XO (Bausch & Lomb Incorporated).

Developing a dermatological photodiagnosis system by optical image analyses and in vivo study.

Dermatological photodynamic therapy (DPDT) involves using systematic photosensitizers in combination with light irradiation treatment to eliminate cancer cells. Therefore, a noninvasive fluorescence photodiagnosis system is critical in DPDT for diagnosing target tissues and demarcating the margin of normal tissues. This study proposes a 375-nm ring LED light module in fluorescence imaging for DPDT applications.

Rapid ranging through evaluation of image distortion.

Distortion is an undesirable aberration found in optical imaging systems, necessitating numerical calibration. However, the fact that image distortion changes with observation distance can be used for ranging. This study developed a rapid, passive-ranging technique, which is simple, incurs low costs, results in minimal interference, and requires few parameters.

Optical imaging with spectrum aberration correction using a filtering macrolens.

A filtering macrolens was developed to simultaneously achieve macro-optical imaging and correct spectrum aberration. The macrolens was a doublet lens comprising a filtering lens and a close-up lens. The shape of the filtering lens was designed to eliminate the optical path differences between the light rays in the absorbing medium.
