The Utility of C-Reactive Protein, Procalcitonin, and Leukocyte Values in Predicting the Prognosis of Patients with Pneumosepsis and Septic Shock.

The predictive value of changes in C-reactive protein (CRP), procalcitonin, and leukocyte levels, which are commonly used in the diagnosis of infection in sepsis and septic shock, remains a topic of debate. The aim of this study was to evaluate the effectiveness of changes in CRP, procalcitonin, and leukocyte counts on the prognosis of 230 patients admitted to the intensive care unit (ICU) with the diagnosis of sepsis and pneumonia-related septic shock between 1 April 2022 and 31 December 2023, and to investigate whether any of these markers have a superior predictive value over the others in forecasting prognosis. This single-center, retrospective, cross-sectional observational study included patients who developed sepsis and septic shock due to community-acquired pneumonia and were admitted to the ICU.

Surgical techniques for cardiac procurement, preparation and perfusion using the Organ Care System.

We provide an audio-visual step-by-step guide to the preparation of a donor heart for the application of normothermic, ex situ cardiac perfusion on the TransMedics Organ Care System using a heart donated after brain death. The use of the Organ Care System increases heart transplantation activity by enabling the utilization of hearts donated after circulatory death, the use of extended criteria grafts and the extension of out-of-body time, which can help overcome geographic or surgical barriers. Ex situ cardiac perfusion is a new technique and is therefore not yet routinely performed in many centres.

In patients with Marfan syndrome, we looked at long-term changes in right ventricular function, tricuspid valve regurgitation and freedom from tricuspid valve repair.

Molecular Identification and Pathogenicity of Species Associated with Wood Canker, Root and Basal Rot in Turkish Grapevine Nurseries.

species are agriculturally important fungi with a broad host range and can be found as endophytic, pathogenic, or opportunistic parasites in many crop plants. This study aimed to identify species in bare-rooted, dormant plants in Turkish grapevine nurseries using molecular identification methods and assess their pathogenicity. Asymptomatic dormant plants were sampled from grapevine nurseries (43) in different regions of the country, and fungi were isolated from plant roots and internal basal tissues.

Serum osmolarity does not predict mortality in patients with respiratory failure.

We aimed to determine the parameters that affect mortality in pulmonary intensive care units that are faster and inexpensive to determine than existing scoring systems. The relationship between serum osmolarity and prognosis was demonstrated for predialysis patients, in acute pulmonary embolism, heart failure, acute coronary syndrome, myocardial infarction, and acute spontaneous intracerebral hemorrhage in the literature. We hypothesized that serum osmolarity, which is routinely evaluated, may have prognostic significance in patients with respiratory failure.

Calculation of conductive polymer-based SO and SO gas sensor mechanisms by using the DFT method.

In this study, we carried out with the DTP (dithieno(3,2-b:2,3-d) pyrrole) molecule which is a member of the conductive polymer class that is one of the topics that have been studied prevalently in recent times, and the density functional theory's (DFT) calculation methods were used to shed light on the sensor mechanisms of its interactions with SOx (SO and SO) sulfur oxides. The changes in the geometric and electronic characteristics of a sensor mechanism designed with the DTP molecule when it encountered sulfur oxides were examined. With these changes, the usability of DTP as a sensor material was proven.

Prediction of compressibility parameters of the soils using artificial neural network.

The compression index and recompression index are one of the important compressibility parameters to determine the settlement calculation for fine-grained soil layers. These parameters can be determined by carrying out laboratory oedometer test on undisturbed samples; however, the test is quite time-consuming and expensive. Therefore, many empirical formulas based on regression analysis have been presented to estimate the compressibility parameters using soil index properties.
