Article Abstract

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.

Department of Medical Lab Technology, College of health and medical technology, Sulaimani Polytechnic University, Sulaimani, 46001, Kurdistan Region, Iraq.

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.

Aim        To compare the results of primary percutaneous coronary intervention (PCI) for non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in patients who recently recovered from COVID-19 with those not previously infected with SARS-CoV-2; to establish prognostic criteria for PCI complications, including stent thrombosis and restenosis (ST and SR) and progression of ischemic heart disease, and to determine ways to prevent them.Material and methods         In 2021, middle-aged patients admitted to the Baku Central Clinical Hospital with a diagnosis of acute coronary syndrome who underwent urgent myocardial revascularization using percutaneous balloon angioplasty of the occluded coronary artery (CA) with implantation of a second-generation intracoronary drug-eluting stent were divided into two observation groups: the main group of 123 patients who had COVID-19 in the previous 6 months, and the control group of 112 patients who were not previously infected with SARS-CoV-2. 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.
