Bistable forespore engulfment in Bacillus subtilis by a zipper mechanism in absence of the cell wall [PDF]
, 2014 To survive starvation, the bacterium Bacillus subtilis forms durable spores. The initial step of sporulation is asymmetric cell division, leading to a large mother-cell and a small forespore compartment. After division is completed and the dividing septum is thinned, the mother cell engulfs the forespore in a slow process based on cell-wall degradation

Animal Models and Experimental Medicine, EarlyView.The flowchart of this research. Abstract Background Dry eye disease (DED) predominantly results from elevated tear film osmolarity, which can not only cause ocular inconvenience but may lead to visual impairments, severely compromising patient well‐being and exerting substantial economic burdens as well.

Computed Flow and Fluorescence Over the Ocular Surface [PDF]
arXiv, 2016 Fluorescein is perhaps the most commonly used substance to visualize tear film thickness and dynamics; better understanding of this process aids understanding of dry eye syndrome which afflicts millions of people. We study a mathematical model for tear film flow, evaporation, solutal transport and fluorescence over the exposed ocular surface during the

Label‐Free Microscale Technologies for Isolation of Heterogeneous Circulating Tumor Cells
Advanced NanoBiomed Research, EarlyView.The isolation of circulating tumor cells (CTCs) from liquid biopsy samples is crucial for cancer treatment and monitoring. This review evaluates primary label‐free isolation methods for capturing heterogeneous CTCs and examines their potential to provide deeper insights into tumor heterogeneity and dynamics of cancer progression.

Concentration ratio for a circular trough with flat receiver [PDF]
arXiv, 2022 We present a simple analytical formula for the geometric concentration ratio of a circular trough optical concentrator coupled to a flat (planar) receiver. The receiver is sized to achieve full collection (no spillage) for any combination of acceptance and rim angle.

TURP Syndrome and Changes in Body Fluid Distribution [PDF]
, 2001 前立腺肥大症の経尿道的前立腺切除術では潅流液に3%のソルビトール液を用いるために,破綻した血管から吸収された潅流液により低ナトリウム性のTUR症候群を起こすことが知られている.潅流液の吸収による体液バランスの変化を61名の患者で測定した.吸収潅流液（V-abs),出血量（B-loss）,細胞内液増加量（ΔICF）,細胞外液増加量（ΔECF）を検査データから計算により求めた.TUR症候群を来した患者群（TURS）と無症状患者群（ASTM）に分けた.出血量はTURS（平均860 ml）がASTM ...

Complex-linear invariants of biochemical networks [PDF]
arXiv, 2012 The nonlinearities found in molecular networks usually prevent mathematical analysis of network behaviour, which has largely been studied by numerical simulation. This can lead to difficult problems of parameter determination. However, molecular networks give rise, through mass-action kinetics, to polynomial dynamical systems, whose steady states are ...

Conversion of the chemical concentration of odorous mixtures into odour concentration and odour intensity: a comparison of methods [PDF]
, 2015 Continuous odour measurements both of emissions as well as ambient concentrations are seldom realised, mainly because of their high costs. They are therefore often substituted by concentration measurements of odorous substances. Then a conversion of the chemical concentrations C (mg m-3) into odour concentrations COD (ouE m-3) and odour intensities OI ...
