This study aims forward to explain the effect of freight transportation on environmental pollution and to investigate the role played by the usage rates of road and railway transportation modes in this relationship. As an auxiliary problem of the research, it was tried to determine whether there is a threshold value for these types of transportation and what consequences will arise in terms of environmental pollution below and above this threshold. For this purpose, the data of OECD countries for the period 2000-2018 were analyzed with the PSTR method.

The objective of this study was to create and characterize an innovative granola, a popular choice in quick breakfasts. The granola samples were sweetened with agave syrup (A), honey (H), and stevia (S) and produced using conventional oven (1) and microwave (2) baking techniques at temperatures of 160°C and 300 W, respectively. Among the samples, H1 exhibited the highest total sugar content (26.

Article Synopsis
  • Orthohantaviruses are significant public health threats, causing various diseases like hemorrhagic fever and hantavirus pulmonary syndrome, so monitoring wild rodents for these viruses is crucial for outbreak preparedness.
  • Researchers conducted a study from 2015 to 2017 in Southern Anatolia but found no evidence of orthohantavirus infections among the trapped rodents.
  • The study suggests that orthohantavirus presence may be influenced by climatic conditions, particularly precipitation and temperature, and emphasizes the need for further research on rodent surveillance in different regions.

Background: To our knowledge, a possible predictive relationship of the multi-inflammatory index (MII) with new-onset atrial fibrillation (AF) after off-pump coronary artery bypass grafting (CABG) has not yet been studied in the literature.

Aims: We aimed to investigate whether the MII is a novel group of hematological markers for predicting postoperative new-onset AF in patients undergoing off-pump CABG.

Methods: A total of 427 patients undergoing isolated off-pump CABG between October 2021 and December 2023 were enrolled in this retrospective observational cohort study and allocated to two groups: the AF group (n = 108) and the non-AF group (n = 319).

  • The study explored how incorporating hydrogen-producing magnesium into minced beef affects its quality and safety over a 12-day storage period at 4 °C.
  • Results showed that samples with hydrogen (H) and hydrogen-producing magnesium (H2-P-Mg) had lower browning and reduced bacterial counts compared to other methods.
  • The use of H2-P-Mg helped in preserving the nutritional quality and safety of the minced beef by minimizing harmful compounds and volatile substances during cold storage.

  • - This study investigates the connection between apoptosis (the process of programmed cell death) and Degenerative Disc Disease (DDD), which affects a lot of people, especially looking at how Modic-type changes in the spine relate to this process.
  • - Ninety adult male patients with low back pain undergoing surgery for lumbar disc herniation were categorized based on magnetic resonance imaging results, and various apoptosis-related proteins were analyzed in their disc tissues.
  • - Results showed specific differences in certain proteins associated with apoptosis among the different Modic types, indicating these proteins may influence DDD's development and progression, and suggesting more research could help develop new treatments targeting these proteins.

We report complete coding sequences of Orthohantavirus dobravaense (Dobrava virus) Igneada strains and phylogenetic characterization of all available complete coding sequences. Our analyses suggested separation of host-dependent lineages, followed by geographic clustering. Surveillance of orthohantaviruses using complete genomes would be useful for assessing public health threats from Dobrava virus.

The effect of using hydrogen-rich water (HRW) in the preparation of rice milk on the nutritional and sensorial properties was evaluated. The physicochemical parameters (pH, Eh7, titratable acidity), sensory properties (color), and minerals (ICP-MS), as well as amino acid (UPLC-ESI-MS/MS), sugar (HPLC-RID), and aroma (SPME-GC/MS) profiles, of four varieties of rice and their milk and waste were examined using Principal Component Analysis (PCA). Results showed that the profile of minerals, sugars, amino acids, and aroma was affected by the use of HRW.

Background And Purpose: Family-centered care (FCC) is a crucial and dynamic philosophy within 21st-century pediatric nursing, offering numerous benefits for both children and their families. It is essential for pediatric nurses to be well-versed in the FCC approach and related practices. The aim of this study is to determine the effect of nurse training on nurses' attitudes towards FCC and on nurses' clinical practices related to FCC.

Objective: There is no study in the literature evaluating the dynamic thiol/disulfide homeostasis in patients with chronic venous insufficiency. Thus, we designed this study to evaluate the dynamic thiol/disulfide homeostasis as a novel indicator of oxidative stress in patients with chronic venous insufficiency.

Methods: This was a prospective case-control study performed at the department of cardiovascular surgery of a tertiary referral hospital in Turkey.

Objective: Breast cancer (BC) is the most common cancer type in women and may be inherited, mostly in an autosomal dominant pattern. The clinical diagnosis of BC relies on the published diagnostic criteria, and analysis of two genes, and , which are strongly associated with BC, are included in these criteria. The aim of this study was to compare BC index cases with non-BC individuals in terms of genotype and diagnostic features to investigate the genotype/demographic information association.

Objective: In this study, we aimed to determine whether plasma calcium level and C-reactive protein albumin ratio (CAR) as well as other demographic and hematological markers are related in predicting severe bleeding after coronary artery bypass grafting (CABG).

Methods: A total of 227 adult patients who underwent CABG at our hospital between December 2021 and June 2022 were prospectively studied. Total amount of chest tube drainage was evaluated within the first 24 hours postoperatively or until the patient was re-explored for bleeding.

Background: Pulmonary arterial hypertension (PAH) is characterized by maladaptation of pulmonary vasculature which is leading to right ventricular hypertrophy and heart failure. miRNAs play a crucial role in the regulation of many diseases such as viral infection, cancer, cardiovascular diseases, and pulmonary hypertension (PH). In this study, we aimed to investigate the expression pattern of eight human plasma miRNAs (hsa-miR-21-3p, hsa-miR-143- 3p, hsa-miR-138-5p, hsa-miR-145-3p, hsa-miR-190a, hsa-miR-204-3p, hsamiR-206, hsa-miR-210-3p) in mild-to-severe PH patients and healthy controls.

Classification of an object behind a random and unknown scattering medium sets a challenging task for computational imaging and machine vision fields. Recent deep learning-based approaches demonstrated the classification of objects using diffuser-distorted patterns collected by an image sensor. These methods demand relatively large-scale computing using deep neural networks running on digital computers.
