A method for recovering CO2 respired by bacterioplankton for analysis of carbon isotopes was adapted for use with standard laboratory equipment without a technically demanding harvest line. The recovered CO2 was more depleted in (14)C than the dissolved organic carbon (DOC) source, which suggests a selective respiration of older carbon.

Background: Peripheral nerve injury commonly results in pain and long-term disability for patients. Recovery after in-continuity stretch or crush injury remains inherently unpredictable. However, surgical intervention yields the most favorable outcomes when performed shortly after injury.

Background: Sinusitis is a common respiratory infection increasingly associated with antibiotic-resistant Staphylococcus aureus, posing significant treatment challenges. The emergence of methicillin-resistant S. aureus (MRSA) in sinus infections necessitates comprehensive profiling of resistance patterns to guide effective therapy.

The immediate results of PCI were assessed according to the TIMI scale; complications were assessed both clinically, by the incidence of severe complications (major adverse cardiovascular events, MACE), and angiographically, by the incidence of early and late ST and SR, and de novo stenosis that developed during the two-year observation period.

Optical imaging offers high sensitivity and specificity for noninvasive cancer detection, but conventional techniques suffer from limited probe accumulation, tissue autofluorescence, and poor depth resolution. Afterglow luminescence overcomes autofluorescence by emitting persistent light after excitation, yet its utility in vivo remains hindered by weak tumor enrichment and two-dimensional readouts lacking spatial context. Here, we report luminescent-magnetic nanoparticles (LM-NPs) coencapsulating luminescent trianthracene (TA) molecules and iron oxide cores within the amphiphilic polymer pluronic-F127.

Background: Revision hip arthroplasty is associated with significant blood loss and a subsequent need for blood transfusion. Intraoperative cell salvage (ICS) is a method of recovering a patient's blood for autologous transfusion. This potentially reduces the need for allogenic blood transfusion (ABT), thus avoiding associated risk and expense.
