Swimming ability and flagellar motility of sperm packets of the volvocine green alga Pleodorina starrii.

Eukaryotic flagella collectively form metachronal waves that facilitate the ability to cause flow or swim. Among such flagellated and planktonic swimmers, large volvocine genera such as Eudorina, Pleodorina and Volvox form bundles of small male gametes (sperm) called "sperm packets" for sexual reproduction. Although these sperm packets reportedly have flagella and the ability to swim, previous studies on volvocine motility have focused on asexual forms and the swimming characteristics of sperm packets remain unknown.

Falls in oxygen saturations accompany electrographic seizures in term neonates: an observational study.

Background: Effective seizure detection is important however, clinical signs of seizure activity may be subtle in neonates. This study aimed to systematically investigate SpO and respiratory pattern changes associated with EEG seizures in term-born neonates.

Method: An observational study in term neonates at risk of seizures admitted to a single tertiary level neonatal intensive care unit.

A Microfluidic Diagnostic Device Capable of Autonomous Sample Mixing and Dispensing for the Simultaneous Genetic Detection of Multiple Plant Viruses.

As an efficient approach to risk management in agriculture, the elimination of losses due to plant diseases and insect pests is one of the most important and urgent technological challenges for improving the crop yield. Therefore, we have developed a polydimethylsiloxane (PDMS)-based microfluidic device for the multiplex genetic diagnosis of plant diseases and pests. It offers unique features, such as rapid detection, portability, simplicity, and the low-cost genetic diagnosis of a wide variety of plant viruses.

The shape effect of flagella is more important than bottom-heaviness on passive gravitactic orientation in .

The way the unicellular, biflagellated, green alga orients upward has long been discussed in terms of both mechanics and physiology. In this study, we focus on the mechanics, i.e.
