Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Instruction Tenapanor potentially affects fluid volume and blood pressure. This study explored its effects on these parameters in patients undergoing peritoneal dialysis (PD). Methods We conducted a single‐arm, prospective observational study that enrolled 10 patients on PD with hyperphosphatemia who were newly initiated on tenapanor.

Copulas Arisen from Degradation-Based Time-to-Failure Models
, 2022 There are a variety of degradation models in the literature, each with a certain effect of random variation around the mean degradation path on the time-to-failure of the device being degraded.

Efficient estimation of the mean time between failures in non-regenerative dependability models [PDF]
Proceedings of the 25th conference on Winter simulation - WSC '93, 1993 In this paper we discuss fast simulation techniques for estimating the steady-state mean time between failures (MTBF) in non-Markovian models of highly dependable systems. The key is to use a ratio representation of the MTBF, in which the denominator is closely related to the probability of a rare event and is therefore amenable to estimation using ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Impact of Electronic Components Thermal Resilience on the Reliability of Radio-Electronic Equipment
Vìsnik Nacìonalʹnogo Tehnìčnogo Unìversitetu Ukraïni Kììvsʹkij Polìtehnìčnij Ìnstitut: Serìâ Radìotehnìka, RadìoaparatobuduvannâThe article focuses on the impact of temperature on the reliability of electronic components, as in non-redundant radio-electronic equipment, the failure of any component typically leads to the failure of the entire device.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
