Nickel is a chemical element that occurs naturally in soil, water, air, plants, and therefore also in food and other living organisms. However, anthropogenic activities related to the production and processing of nickel can cause its increased concentration in the environment, which is a risk to wildlife and thus to human health. Nickel and its compounds are currently considered immunotoxic and carcinogenic agents that cause a number of health problems.

Antibiotics (Basel)

December 2024

Faculty of Medicine, Comenius University in Bratislava, 5th Department of Internal Medicine, University Hospital Bratislava, Ružinov, Špitálska 24, 813 72 Bratislava, Slovakia, and Ružinovská 4810/6, 821 01 Bratislava, Slovakia.

In healthcare environments with high microbial loads, effective infection control measures are critical for reducing airborne and surface contamination. One of the novel modalities in the achievement of these goals is the use of antimicrobial mists, such as droplets, in the form of dry fog. Although the usage of dry fog in the disinfection of contained healthcare microenvironments is well known, the effect of such a system in terms of a meaningful reduction in the microbial burden in an open inpatient ward is unclear.

Background: The left internal thoracic artery (LITA) has been widely accepted as the standard for revascularizing the left anterior descending artery during coronary artery bypass grafting (CABG) surgery. However, in 10-20% of cases, the LITA may lead to unsecured side branches to the chest wall, particularly the lateral costal artery (LCA), potentially resulting in postoperative chest angina.

Case Presentation: We report the case of a 58-year-old patient who experienced persistent angina eight months after having undergone coronary artery bypass grafting (CABG) due to the steal phenomenon caused by a thick lateral costal artery (LCA).

Article Synopsis
  • The study used a hybrid B3LYP version of Density Functional Theory to analyze the properties of mustard-type cancer drugs, melphalan and bendamustine, in water, focusing on their geometry, vibrational characteristics, and various electrical properties.
  • Findings showed that these drugs have low ionization energies, indicating significant antioxidant potential, with melphalan's zwitterionic form being more stable in water compared to bendamustine's.
  • Advanced calculations using the DLPNO-CCSD(T) method confirmed that the canonical form of bendamustine is more stable in water than its zwitterionic counterpart, along with noting particularly high dipole moments for some structures.

Neoplastic transformation of B cells of the post-germinative center can lead to oncohematological dyscrasias, which often results in an abnormal production of monoclonal immunoglobulin light chains. The non-physiological production of large amounts of IgG light chains leads to the formation of extracellular deposits called 'aggregomas' and rare conditions such as light chain crystal deposition disease. Kidney manifestations and heavy-chain deposition disease can also occur in plasma cell dyscrasias, emphasizing the role of IgG misfolding and aggregation.

In recent decades, global climate change and rapid urbanization have aggravated the urban heat island (UHI) effect, affecting the well-being of urban citizens. Although this significant phenomenon is more pronounced in larger metropolitan areas due to extensive impervious surfaces, small- and medium-sized cities also experience UHI effects, yet research on UHI in these cities is rare, emphasizing the importance of land surface temperature (LST) as a key parameter for studying UHI dynamics. Therefore, this paper focuses on the evaluation of LST and land cover (LC) changes in the city of Prešov, Slovakia, a typical medium-sized European city that has recently undergone significant LC changes.
