Stable ^{205}Tl ions have the lowest known energy threshold for capturing electron neutrinos (ν_{e}) of E_{ν_{e}}≥50.6  keV. The Lorandite Experiment (LOREX), proposed in the 1980s, aims at obtaining the longtime averaged solar neutrino flux by utilizing natural deposits of Tl-bearing lorandite ores.

Article Synopsis
  • Radioactive nuclei that live for millions of years help us understand the Sun's formation and the nucleosynthesis happening when it was born, with lead (Pb) being a key example.
  • Recent measurements of the weak decay of ionized thallium (Tl) provided a more accurate half-life, which was found to be 4.7 times longer than previously thought, thus reducing uncertainty in our calculations.
  • Using these improved decay rates, researchers calculated lead yields in asymptotic giant branch (AGB) stars, confirmed isolation times for solar material, and validated the theory that the Sun formed in a long-lived molecular cloud.

The nuclear two-photon or double-gamma (2γ) decay is a second-order electromagnetic process whereby a nucleus in an excited state emits two gamma rays simultaneously. To be able to directly measure the 2γ decay rate in the low-energy regime below the electron-positron pair-creation threshold, we combined the isochronous mode of a storage ring with Schottky resonant cavities. The newly developed technique can be applied to isomers with excitation energies down to ∼100  keV and half-lives as short as ∼10  ms.

This commentary examines the resilience of primary health care in Ukraine amidst the ongoing war, drawing a few reflections relevant for other fragile and conflict-affected situations. Using personal observations and various published and unpublished reports, this article outlines five reflections on the strengths, challenges, and necessary adaptations of Primary Health Care (PHC) in Ukraine. It underscores the concerted efforts of the government to maintain public financing of PHC, thereby averting system collapse.

Today surgical site infections (SSIs) remain the second among hospital acquired infections in Europe and the USA. as a pathogen of nosocomial infections occur more frequently in surgical hospitals. The work was aimed to establish the effect of local anesthetics against planktonic forms and biofilm-formation of clinical strains and the relationship between the sensitivity of strains to local anesthetics and antiseptics .

Objective: The aim: Analyze the dynamics of indicators in platelet hemostasis in polytrauma and enlarged body mass index.

Patients And Methods: Materials and methods: A comprehensive study of hemostasis was performed in 224 sick with polytrauma and high body mass index within a month and on the 360th day.

Results: Results: In Group I, the aggregation time was shortened during stimulation of ristomycin by 25% from day 1 to day 3.

Background And Aim: VAP remains the second leading cause of death among the patients with nosocomial infections and its incidence varies significantly from 5% to 60% reaching on average 10 %. It is of crucial importance to develop novel treatment approaches and optimize the existing ones. Thus, the aim of this pilot study was to study the laboratory-microbiological effect of inhaled aminoglycosides in a complex treatment of patients with ventilator-associatedpneumonia(VAP).

BACKGROUND The conflict in Ukraine during the past year has resulted in increased deaths and injuries to soldiers and civilians from military weapons and large and small caliber firearms. Unlike clinicians in some Western countries, until recently, clinicians working in Ukraine hospitals had little experience managing patients with gunshot wounds. CASE REPORT A 16-year-old boy was admitted as an emergency following a gunshot wound to the back of the neck from a Makarov pistol.

Background: The aim of this study was to evaluate the hemodynamic protective effects of perioperative ventilation in pressure-controlled ventilation (PCV) and adaptive support ventilation (ASV) modes based on non-invasive hemodynamic monitoring indicators.

Methods: The study included 32 patients who were scheduled for planned open abdominal surgery. Depending on the chosen ventilation strategy, patients were included in two groups of PCV mode ventilation (n=14) and ASV mode ventilation (n=18).

Healthcare-associated infections (HCAIs) are among the most prominent medical problems worldwide. In the context of increasing antibiotic resistance globally, the use of antiseptics as the main active agent and potentiator of antibiotics for the treatment of purulent-inflammatory complications of traumatic wounds, burns, and surgical wounds can be considered to tackle opportunistic infections and their prevention during war. This study presents a comparative investigation of the antimicrobial efficacy of antiseptics used for surgical antisepsis and antiseptic treatment of skin, mucous membranes, and wounds against multidrug-resistant clinical isolates of as a wound pathogen of critical priority (according to the WHO).

Enhanced Recovery After Surgery (ERAS) protocols are increasingly used in the perioperative period around the world. The concept of goal-directed fluid therapy (GDT) is a key element of the ERAS protocols. Inadequate perioperative infusion therapy can lead to a number of complications, including the development of an infectious process, namely surgical site infections, pneumonia, urinary tract infections.

The ongoing conflict in Ukraine continues to generate many complex traumatic injuries and provides unique challenges to anaesthesiologists who provide medical care at various levels of medical evacuation. We report the successful use of an ultrasound-guided continuous erector spinae plane (ESP) block in a patient with severe posterolateral chest trauma. The acute perioperative outcome of the patient was improved with the ESP block, the main benefits being excellent analgesia and minimal postoperative morphine requirements without influencing the risk of bleeding and coagulopathy.

Introduction: The perioperative period of any surgery is accompanied by immune suppression. The level of Toll-like receptor 4 (TLR4) is known to increase in inflammation and after nerve injury and contributes to the development of neuropathic pain. The interaction of TLRs in response to the effect of opioids results in paradoxical hyperalgesia.

Objective: The aim: To review the available results for genetic influences on pain syndrome development.

Patients And Methods: Materials and methods: In the period from 2009 to 2020, a total of 45 research papers describing the key points of genetic influences on pain mechanisms in both adults and children were published in Ukrainian and English and they are now included in the PubMed, EMBASE, Cochrane, and Google Scholar research databases.

Conclusion: Conclusions: Pain is a comprehensive characteristic of a person; therefore, it is inevitable that several genes with little individual effect interact with each other and environmental factors, influencing pain susceptibility and chronic pain syndrome manifestation.
