Combining Fresnel and block prisms to measure large angles of strabismic deviation.

Purpose: A method was developed to measure strabismic angles >50 by stacking commercially available Fresnel and block prisms in the same direction ("piggyback prisms").

Methods: With a laser pointer (wavelength of 532 nm) as the light source, the deviation of the laser spot produced by the stacked prisms was measured on a tangent screen placed 100 cm away from the prisms. To the obtained data with combinations of Fresnel prisms (5-40) and block prisms (10-50), a cubic surface function was fitted by polynomial regression.

Molecular phylogeny and taxonomy of (Asparagaceae) on Shikoku Island, Japan, including five new species, one new subspecies, and two new status assignments.

Japan has 16 native species of the genus Tratt. (Asparagaceae). A recent study on based on field surveys and molecular phylogenetic analyses resulted in the discovery of six unknown taxa in Kochi Prefecture, Shikoku Island, southwestern Japan.

Improving the Detection Sensitivity of a New Rapid Diagnostic Technology for Severe Acute Respiratory Syndrome Coronavirus 2 Using a Trace Amount of Saliva.

The early diagnosis and isolation of infected individuals with coronavirus disease 2019 (COVID-19) remain important. Although quantitative polymerase chain reaction (qPCR) testing is considered the most accurate test available for COVID-19 diagnosis, it has some limitations, such as the need for specialized laboratory technicians and a long turnaround time. Therefore, we have established and reported a rapid diagnostic method using a small amount of saliva as a sample using a lightweight mobile qPCR device.

Short ramus reconstruction for hemi-mandibulectomy defect: Case reports.

Reconstruction of the mandible following hemimandibulectomy is difficult and complex. The appropriate approach to condylar reconstruction remains controversial. In this report, the authors propose the concept of "short ramus reconstruction" after hemimandibulectomy.

Synthesis of many different types of organic small molecules using one automated process.

Small-molecule synthesis usually relies on procedures that are highly customized for each target. A broadly applicable automated process could greatly increase the accessibility of this class of compounds to enable investigations of their practical potential. Here we report the synthesis of 14 distinct classes of small molecules using the same fully automated process.

Mechanisms of G1 cell cycle arrest and apoptosis in myeloma cells induced by hybrid-compound histone deacetylase inhibitor.

Objectives: Histone deacetylase (HDAC) inhibitors are new therapeutic agents, used to treat various types of malignant cancers. In the present study, we investigated the effects of Ky-2, a hybrid-compound HDAC inhibitor, on the growth of mouse myeloma cells.

Materials And Methods: Myeloma cells, HS-72, P3U1, and mouse normal cells were used in this study.
