Role of atmospheric rivers in shaping long term Arctic moisture variability.

Atmospheric rivers (ARs) reaching high-latitudes in summer contribute to the majority of climatological poleward water vapor transport into the Arctic. This transport has exhibited long term changes over the past decades, which cannot be entirely explained by anthropogenic forcing according to ensemble model responses. Here, through observational analyses and model experiments in which winds are adjusted to match observations, we demonstrate that low-frequency, large-scale circulation changes in the Arctic play a decisive role in regulating AR activity and thus inducing the recent upsurge of this activity in the region.

Atmospheric blocking and temperatures in the Antarctic Peninsula.

The Antarctic Peninsula (AP) has displayed a propensity for persistent blocking ridges and anticyclonic conditions, particularly during recent summertime extreme weather events. This study investigates atmospheric blocking patterns over the AP through historical (1981-2010) and future (2071-2100, SSP5-8.5) periods using ERA5 reanalysis and six CMIP6 models, including multi-member realizations from two models totaling ten simulations.

Large-scale and regional climatic influences on surface temperature and precipitation in the South Shetland Islands, northern Antarctic Peninsula.

Using data from SCAR observations, ERA5 reanalysis, and regional climate model simulations (RACMO), we examined the influence of large- and regional-scale climate forcing on temperature and precipitation variations in the South Shetland Islands (SSI). Specifically, we focused on understanding how regional climate indices influence the temporal variability of temperature and precipitation on the SSI. Our findings indicate that both large- and regional-scale climate indices significantly impact the interannual and seasonal temperature variability in the SSI.

Ertapenem plus meropenem combination treatment in carbapenem-resistant Klebsiella pneumoniae bacteremia: an analysis of 53 cases.

Herein, we aimed to describe the outcomes of patients with blood stream infections due to carbapenem-resistant Klebsiella pneumoniae (CR-Kp) who received ertapenem plus meropenem combination treatment (EMCT). A total of 53 patients with culture proven CR-Kp bacteremia treated with ertapenem + meropenem were included. The patients with secondary bacteremia due to urinary tract infection exhibited a significantly lower 1-month mortality (OMM), particularly in those with microbiological eradication and those with end-of-treatment success.

Volatile organic compounds measured by proton transfer reaction mass spectrometry over the complex terrain of Quintero Bay, Central Chile.

This research provides new evidence regarding the different kinds of air quality episodes, and their underlying mechanisms, that frequently impact the urban area of Quintero Bay in Central Chile, which is located along complex coastal terrain and is surrounded by industries. The monitoring campaign was carried out in January 2022 and encompassed two distinctive meteorological regimes. The first part of the month was dominated by a coastal low centered to the south of Quintero, which resulted in prevailing northerly flow (or weak southerlies) and a deep cloud-topped marine boundary layer.

[A Case of Plasmodium vivax Complicated with Reactive Hemophagocytic Syndrome].

Serum estradiol level predicts acute kidney injury in medical intensive care unit patients.

Previous studies have shown that serum estradiol (E2) levels can predict mortality in intensive care unit patients. Our study investigated the predictive role of admission estradiol level on patient mortality and development of acute kidney injury in medical intensive care unit patients with a wide range of diagnoses. We conducted a prospective cohort study using serum samples from hospitalized patients in medical, cardiac, and pulmonary intensive care units at the Ege University Hospital within 6 months.

Effect of surface treatment, ferrule height, and luting agent type on pull-out bond strength of monolithic zirconia endocrowns.

Purpose: To evaluate the effect of different surface treatments, ferrule heights, and luting agents on the pull-out bond strength (PBS) of computer-aided design/computer-aided manufacturing (CAD-CAM) monolithic endocrowns.

Methods: After endodontic treatment and preparation for two endocrown designs (ferrule height 0 mm or 2 mm), CAD-CAM monolithic zirconia endocrowns were fabricated for 80 mandibular molars. Each endocrown design group was then divided on the basis of surface treatment into two groups: half were air-abraded and half were air-abraded/laser-irradiated.

Central tropical Pacific convection drives extreme high temperatures and surface melt on the Larsen C Ice Shelf, Antarctic Peninsula.

Northern sections of the Larsen Ice Shelf, eastern Antarctic Peninsula (AP) have experienced dramatic break-up and collapse since the early 1990s due to strong summertime surface melt, linked to strengthened circumpolar westerly winds. Here we show that extreme summertime surface melt and record-high temperature events over the eastern AP and Larsen C Ice Shelf are triggered by deep convection in the central tropical Pacific (CPAC), which produces an elongated cyclonic anomaly across the South Pacific coupled with a strong high pressure anomaly over Drake Passage. Together these atmospheric circulation anomalies transport very warm and moist air to the southwest AP, often in the form of "atmospheric rivers", producing strong foehn warming and surface melt on the eastern AP and Larsen C Ice Shelf.

Evaluation of dentinal tubule penetration of Irritrol and chlorhexidine irrigating solutions activated using EDDY and photon-initiated photoacoustic streaming.

The aim of the study was to compare the penetration depth and percentage of Irritrol and chlorhexidine (CHX) solutions into dentinal tubules using conventional needle irrigation (CI), EDDY, and photon-induced photoacoustic streaming (PIPS). Sixty oval shaped mandibular premolar teeth were divided into two main groups according to the irrigating solutions as follows; Irritrol and CHX, which were later randomly divided into three subgroups according to the activation technique; CI, EDDY and PIPS (n = 10). Following the irrigation activation procedures, all roots were horizontally sectioned at 3 (apical), 8 (middle), and 13 (coronal) mm from the root apex and then examined with confocal laser scanning microscope (CLSM).

Projected increases in surface melt and ice loss for the Northern and Southern Patagonian Icefields.

The Northern Patagonian Icefield (NPI) and the Southern Patagonian Icefield (SPI) have increased their ice mass loss in recent decades. In view of the impacts of glacier shrinkage in Patagonia, an assessment of the potential future surface mass balance (SMB) of the icefields is critical. We seek to provide this assessment by modelling the SMB between 1976 and 2050 for both icefields, using regional climate model data (RegCM4.
