Prediction of pore fouling by microparticles is still challenging and remains a difficult step to optimize membrane and filtration processes. The scientific issue consists in determining the relevant operation parameters controlling the capture of particles and the clogging of the filter. In this study, we have developed for a dead-end and cross-flow filtration a poly-dimethylsiloxane (PDMS) de...

OBJECTIVE To describe a new murine model of cigarette smoke-induced emphysema. METHODS Twenty-four male Wistar rats were divided into two groups: the cigarette smoke group, comprising 12 rats exposed to smoke from 12 commercial filter cigarettes three times a day (a total of 36 cigarettes per day) every day for 30 weeks; and the control group, comprising 12 rats exposed to room air three time...

Particle passage from the reticulorumen (RR) depends on particle density and size. Forage particle density and size are related and change over time in the RR. Particle density mainly influences sorting in the reticulum, whereas particle size influences particle retention in the fibre mat of stratified rumen contents ('filter-bed' effect). We investigated these effects independently, by inserti...

We have obtained 3.3–3.4-lm spectro-images of Jupiter including CH4 and H3 emission lines from both polar regions at the Gemini North telescope. We find that the peak of the 3-lm CH4 northern bright spot is located at 200 (SysIII) longitude, 20 west of the center of the 8-lm north-polar bright spot, and does not coincide with the 3-lm H3 bright spot. We derive high temperatures (500–850 K) from...

BACKGROUND & AIMS Lean mass (LM) is an important parameter in clinical outcomes, which highlights the necessity of reliable tools for its estimation. The adductor pollicis muscle thickness (APMT) is easily accessible and suffers minimal interference from the adjacent subcutaneous fat tissue. OBJECTIVE To assess the relationship between the APMT and LM in a sample of Southern Brazilian adults....

Concurrent meniscal repair with anterior cruciate ligament (ACL) reconstruction has shown good clinical outcomes, but it has a considerable risk of progressing to post-traumatic osteoarthritis of the knee. Here we investigated postoperative changes in the position of the lateral meniscus (LM) and assessed the short-term clinical results after concurrent LM repair with ACL reconstruction. Twenty...

The Oriens-lacunosum moleculare (O-LM) subtype of interneuron is a key component in the formation of the theta rhythm (8 12 Hz) in the hippocampus. It is known that the CA1 region of the hippocampus can produce theta rhythms in vitro with all ionotropic excitation blocked, but the mechanisms by which this rhythmicity happens were previously unknown. Here we present a model suggesting that indiv...

Regulation of M current (lM) by intracellular free calcium was studied in dissociated bullfrog sympathetic ganglion B cells using whole-cell recording, intracellular perfusion, and confocal calcium imaging. BAPTA (20 mM) and appropriate amounts of calcium were added to pipette solutions to clamp calcium at different levels. A high concentration of BAPTA itself mildly inhibited lM. Intracellular...
