Para-Anastomotic Pseudoaneurysms as a Long-Term Complication After Surgical Treatment of Peripheral Artery Disease: Clinical Characteristics and Surgical Treatment.

Peripheral arterial disease (PAD) is becoming an increasingly prevalent clinical issue, leading to a growing number of patients requiring surgical interventions. Consequently, there is an increasing occurrence of para-anastomotic aneurysms as late complications following primary treatment for PAD. These aneurysms typically arise at the sites of graft implantation and necessitate individualized management strategies based on factors such as location, size, and the patient's overall condition.

Capillary electrophoretic analysis of ionic content in exhaled breath condensate and pH monitoring as a non-invasive method in gastroesophageal reflux disease diagnostics.

In this study, the ionic profile and pH of exhaled breath condensate (EBC) in a group of patients with acid and weakly acid reflux and no-reflux controls were compared. A portable sampler was used for non-invasive EBC collection from five exhalations. The ionic profile (anions, cations, organic acids) and pH of the collected EBC samples were measured by capillary electrophoresis with contactless conductivity detection and a pH microelectrode, respectively.

Optimization of background electrolyte composition for simultaneous contactless conductivity and fluorescence detection in capillary electrophoresis of biological samples.

In this article, optimization of BGE for simultaneous separation of inorganic ions, organic acids, and glutathione using dual C D-LIF detection in capillary electrophoresis is presented. The optimized BGE consisted of 30 mM 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid, 15 mM 2-amino-2-hydroxymethyl-propane-1,3-diol, and 2 mM 18-crown-6 at pH 7.2 and allowed simultaneous separation of ten inorganic anions and cations, three organic acids and glutathione in 20 min.

Evaluation of Important Analytical Parameters of the Peptest Immunoassay that Limit its Use in Diagnosing Gastroesophageal Reflux Disease.

Goal: To evaluate the analytical parameters of a lateral flow (LF) pepsin immunoassay (Peptest) and assess its suitability in the diagnostics of gastroesophageal reflux disease (GERD).

Background: Peptest is a noninvasive assay to analyze pepsin in saliva, intended for use in GERD diagnostics. Although commercialized, fundamental studies on its performance are missing.

Sensitive determination of malondialdehyde in exhaled breath condensate and biological fluids by capillary electrophoresis with laser induced fluorescence detection.

In this work, a sensitive capillary electrophoresis method with laser induced fluorescence detection for determination of malondialdehyde in various biological fluids was developed. Malondialdehyde reacts with thiobarbituric acid under optimized conditions of pH=2, reaction time of 60min and temperature of 90°C, yielding an adduct that can be separated in a 50mM sodium borate background electrolyte at pH 9. The separation of the formed adduct was accomplished in less than 6min with limit of detection of 1.

Capillary electrophoresis in the analysis of biologically important thiols.

In this review article, CE methods for analysis of biologically important thiols are overviewed. The article covers the period from the previously published comprehensive review in 2004 until mid-2016, with emphasis on various detection modes, novel approaches for sample preconcentration, and applications in clinical practice. The most commonly used detection methods, such as conductometry or absorbance detection, although universally applicable and available in most commercial instruments have low sensitivity and have only limited use in thiol analysis.
