Cell volume primarily represents the amount of water in a cell. Osmotically active metabolites and mechanical forces can cause changes in cell volume, but cell volume is under feedback control around a characteristic set point. Traditionally, the analysis of cell volume regulation treats the cell as a semipermeable bag with osmotic pressure converted to hydrostatic pressure at the membrane. How...

Near-hanging injury is not an uncommon occurrence in children. Surprisingly, little discussion of this topic occurs in the pediatric literature. Previous reports note that children who present with an initial pH less than 7.2, apnea or agonal respiration, or who subsequently require mechanical ventilation, either die or survive with severe neurologic residua. We report a series of three pediatr...

BACKGROUND Hanging is the most frequently used method of suicide in the UK and has high case fatality (>70%). AIMS To explore factors influencing the decision to use hanging. METHOD Semi-structured qualitative interviews with 12 men and 10 women who had survived a near-fatal suicide attempt. Eight respondents had attempted hanging. Data were analysed thematically and with constant compariso...

Enrichment of zeolite and sponge as ethylene absorbent with potassium permanganate was theidea of this study to provide an efficient way to scavenge ethylene during storage period ofthree Rosa hybrida cv. ‘Shiraz’, ‘Avalanche’, and ‘After-party’ cut flowers. A preliminaryexperiment revealed that two mL of potassium permanganate solution (1 mM) was enough toenrich two gra...

Water is the dominant ingredient of cells and its dynamics are crucial to life. We and others have suggested a physical picture of the cell as a soft, fluid-infiltrated sponge, surrounded by a water-permeable barrier. To understand water movements in an animal cell, we imposed an external, inhomogeneous osmotic stress on cultured cancer cells. This forced water through the membrane on one side,...

Nearshore marine benthic algal communities along the western Antarctic Peninsula harbour extremely high densities of amphipods that probably play important roles in nutrient and energy flow. This study extends our evaluation of the importance of amphipods in the nearshore Antarctic Peninsular benthic communities and focuses on sponge associations. We found a mean density of 542 amphipods per li...

Hanging is violent asphyxial death. The objective of this study is to assess the data of hanging cases. A descriptive-retrospective study was conducted. We studied 244 hanging cases autopsied in Forensic Division, Department of Pathology, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand, between January 2001 and December 2013. The study included 197 men (80.7%) an...
