The Effect of Molecular Adsorbent Recirculating System in Patients With Liver Failure: A Case Series of 44 Patients.

Background: Liver failure is associated with a high mortality rate, with many patients requiring transplant for definitive treatment. The Molecular Adsorbent Recirculating System (MARS) is a nonbiologic system that provides extracorporeal support. Literature on MARS therapy is mixed: outcomes support MARS therapy for patients with isolated acute liver failure, but data on patients with chronic disease is varied.

"Novel Management of Depression Using Ketamine in the Intensive Care Unit".

Ketamine, a dissociative anesthetic, induces improvement in depressive symptoms by antagonizing glutaminergic NMDA receptors. Ketamine has been used previously in outpatient setting for treatment-resistant depression, but we showcase its utility in depression management at the Intensive Care Unit (ICU). Can ketamine be used for depression treatment in ICU patients? A retrospective chart review of ICU patients was done at a tertiary center from 2018 to 2021, to assess the ketamine usage.

Simulation Method for Testing Aerosol Mitigation Strategies: An Observational Study.

Background: Frontline health care workers who perform potentially aerosol-generating procedures, such as endotracheal intubations, in patients with coronavirus disease 2019 may be at an increased risk of exposure to severe acute respiratory syndrome coronavirus 2. To continue to care for patients with coronavirus disease 2019, minimizing exposure is paramount. Using simulation, we devised a testing method to evaluate devices that may mitigate the spread of aerosol and droplet-sized particles.

Novel repurposing of a Laerdal Airway trainer to simulate aerosolisation.

COVID-19 has claimed over 200 000 lives in the USA and put healthcare workers at risk. Healthcare workers have an increased exposure risk from aerosol-generating procedures such as endotracheal intubation. New barrier designs such as the acrylic box and horizontal plastic drape have emerged to reduce exposure to airborne particles.

Use of a simulation-based advanced resuscitation training curriculum: Impact on cardiopulmonary resuscitation quality and patient outcomes.

Background: Despite a continued focus on improved cardiopulmonary resuscitation quality, survival remains low from in-hospital cardiac arrest. Advanced Resuscitation Training has been shown to improve survival to hospital discharge and survival with good neurological outcome following in-hospital cardiac arrest at its home institution. We sought to determine if Advanced Resuscitation Training implementation would improve patient outcomes and cardiopulmonary resuscitation quality at our institution.

Acute pancreatitis-induced takotsubo cardiomyopathy and cardiogenic shock treated with a percutaneous left ventricular assist device.

A 63-year-old man was admitted for severe acute pancreatitis. On day 3 of hospitalisation, he developed shortness of breath and acute pulmonary oedema. Echocardiogram revealed global hypokinesis with a left ventricular ejection fraction of 20%, and he was diagnosed with takotsubo cardiomyopathy.

The effects of elevated temperatures and various time-temperature combinations on the development of Brachiola (Nosema) algerae N. Comb. in mammalian cell culture.

Nosema algerae Vávra and Undeen 1970, a microsporidian known to cause infection in mosquitoes, develops in mammalian cell cultures at 24-35 degrees C and in the tails and footpads of athymic mice. More recently it has been reported to grow at 38 degrees C in human cell culture. The present study is a two-part temperature/development examination.

Infrared observations of the jovian system from voyager 2.

Infrared spectra obtainedfrom Voyager 2 have provided additional data on the Jovian system, complementing those obtained from Voyager 1. The abundance ratio of ethane to acetylene in Jupiter's atmosphere appears to be about three times larger in the polar regions than at lower latitudes. A decidedly hemispherical asymmetry exists, with somewhat higher ratios prevailing in northern latitudes.

Infrared observations of the jovian system from voyager 1.

The infrared spectroscopy and radiometry investigation has obtained spectra of Jupiter and its satellites between approximately 180 and 2500 cm(-1) with a spectral resolution of 4.3 cm(-1). The Jupiter spectra show clear evidence of H(2), CH(4) C(2)H(2), C(2)H(6), CH(3)D, NH(3), PH(3), H(2)O, and GeH(4).

Apollo 16 Geochemical X-ray Fluorescence Experiment: Preliminary Report.

The lunar surface was mapped with respect to magnesium, aluminum, and silicon as aluminum/ silicon and magnesium/ silicon intensity ratios along the projected ground tracks swept out by the orbiting Apollo 16 spacecraft. The results confirm the observations made during the Apollo 15 flight and provide new data for a number of features not covered before. The data are consistent with the idea that the moon has a widespread differentiated crust (the highlands).

Apollo 15 Geochemical X-ray Fluorescence Experiment: Preliminary Report.

Although only part of the information from the x-ray fluorescence geochemical experiment has been analyzed, it is clear that the experiment was highly successful. Significant compositional differences among and possibly within the maria and highlands have been detected. When viewed in the light of analyzed lunar rocks and soil samples, and the data from other lunar orbital experiments (in particular, the Apollo 15 gamma-ray spectroscopy experiment), the results indicate the existence of a differential lunar highland crust, probably feldspathic.

Infrared spectroscopy experiment on the mariner 9 mission: preliminary results.

The Mariner 9 infrared spectroscopy experiment has provided goodquality spectra of many areas of Mars, predominantly in the southern hemisphere. Large portions of the thermal emission spectra are significantly affected by dust with a silicon oxide content approximately corresponding to that of an intermediate igneous rock, thus implying that Mars has undergone substantial geochemical differentiation. Derived temperature profiles indicate a warm daytime upper atmosphere with a strong warming over the south polar cap.

Electron microprobe analysis of lunar samples.

Plagioclase feldspar, clinopyroxene, and ilmenite in a polished thin section of a type A crystalline rock were analyzed. The clinopyroxene grains are compositionally variable, and both high Ca and low Ca phases are present. The plagioclase is compositionally homogeneous.

Lunar ring dikes from orbiter I.

Orbiter photographs of the wall of a large circular formation on the moon show that the wall is a convex body resembling a flow of viscous lava. The slopes are less than the angle of repose of dry rock; hence an explanation in terms of mass wastage is hard to support. The viscosity is approximately 10(13) centimeter-gram- second units, indicating an acid lava.

Gases in Tektite Bubbles.

Spectroscopic analysis of light produced by electrodeless discharge in a tektite bubble showed the main gases in the bubble to be neon, helium, and oxygen. The neon and helium have probably diffused in from the atmosphere, while the oxygen may be atmospheric gas incorporated in the tektite during its formation.
