Вивчення ядерцевих організаторів тварин дає можливість оцінити рівень функціональної активності рибосомальних генів 18S/28S, які беруть участь у біосинтезі білка. Метою роботи було дослідження ознак активності ядерець у інтерфазних клітинах крові кролів різних порід української селекції.
У експерименті використали самок кролів 4-місячного віку порід полтавське срібло (n=30), каліфорнійська (n=25) їх гібридів (n=21).Зони ядерця у інтактних лімфоцитах крові досліджували за методом Howellend Black (1980). Препарати фарбували розчином 50% AgNO3 з додаванням 1- % розчину мурашиної кислоти і інкубували у вологій камері за температури +60о С. Мікроскопування проводили за допомогою мікроскопа «ZEISS, Germany» (збільшення 10×100). У кожної тварини досліджували щонайменше 200 інтерфазних клітин. Активність ядерець оцінювали за параметрами:середня кількість ядерець у ядрі (nЯО), сумарна площа ядерець в ядрі (ΣSЯО, мкм2), частка площі ядерця у площі ядра лімфоцита (чΣSЯО, %). Статистичний аналіз здійснювали за стандартними програмами варіаційної статистики, що входить у пакет програм «STATISTICA» (2020).
Середнє число ядерець на клітину варіювалось від – 1,70±0,08 у кролів каліфорнійської породи до 5,90±0,29 у гібридних тварин. Виявлена статистично значуща різниця (р<0,05) між дослідними групами чистопородних і гібридних кролів. Коефіцієнт варіації показника середньої кількості ядерець на клітину знаходився на середньому рівні мінливості: 20,58%у кролів породи полтавське срібло,19,50%, у каліфорнійської породи і 16,49% у гібридних. Сумарна площая дерець у клітині у всіх дослідних тварин варіювала від 5 мкм2 у однієї з особин каліфорнійської породи до 12 мкм2 у особини гібридного походження. Частка площі ядерця від площі ядра у кролів породи полтавське срібло, каліфорнійська і гібридів склала 26,10±1,80%, 24,30±1,62 і 29,40±2,50 відповідно.
Кореляційний аналіз виявив статистично достовірний зв’язок між числом ядерець на клітину та сумарною площею ядерця в ядрі клітини (r=0,54, р<0,01) та між числом ядерець на клітину та часткою площі ядерця від площі ядра (r=0,28, р<0,05) у кролів породи полтавське срібло.
Встановлено поліморфізм за дослідженими параметрами активності ядерець у інтактних лімфоцитах периферійної крові кролів порід полтавське срібло, каліфорнійська і гібридів.
Доведено існування статистично значущої різниці між дослідними групами чистопородних і гібридних кролів за кількістю ядерець на клітину, сумарною площею ядерець на клітину і часткою ядерця від площі ядра лімфоцита.
Результати порівняльного аналізу досліджених параметрів активності ядерець у лімфоцитах периферійної крові кролів порід полтавське срібло, каліфорнійської і гібридів вказують на більш високу активність ядерець у тварин гібридного походження.

Abstract
We present star formation rates (SFRs), the mass–metallicity relation (MZR), and the SFR-dependent MZR across redshifts 4–10 using 81 star-forming galaxies observed by the JWST NIRSpec employing both low-resolution PRISM and medium-resolution gratings, including galaxies from the JWST Advanced Deep Extragalactic Survey (JADES) GOODS-N and GOODS-S fields, the JWST-PRIMAL Legacy Survey, and additional galaxies from the literature in the A2744, SMACS-0723, RXJ2129, BDF, COSMOS, and MACS1149 fields. These galaxies span a 3 dex stellar mass range of 107 < M

. Our findings align with previous observations up to z = 8 for the MZR and indicate no deviation from the local Universe fundamental metallicity relation (FMR) up to this redshift. Beyond z = 8, we observe a significant deviation (∼0.27 dex) in FMR, consistent with recent JWST findings. We also integrate Cosmic Evolution Early Release Science (135 galaxies) and JADES (47 galaxies) samples with our data to study the metallicity evolution with redshift in a combined sample of 263 galaxies, revealing a decreasing metallicity trend with a slope of 0.067 ± 0.013, consistent with IllustrisTNG and EAGLE but contradicting the FIRE simulations. We introduce an empirical mass–metallicity–redshift relation:

, which accurately reproduces the observed trends in metallicity with both redshift and stellar mass. This trend underscores the “Grand Challenge” in understanding the factors driving high-redshift galactic metallicity trends, such as inflow, outflow, and active galactic nucleus/stellar feedback—and emphasizes the need for further investigations with larger samples and enhanced simulations.

Abstract
The structure and chemistry of the dusty interstellar medium (ISM) are shaped by complex processes that depend on the local radiation field, gas composition, and dust grain properties. Of particular importance are polycyclic aromatic hydrocarbons (PAHs), which emit strong vibrational bands in the mid-infrared, and play a key role in the ISM energy balance. We recently identified global correlations between PAH band and optical line ratios across three nearby galaxies, suggesting a connection between PAH heating and gas ionization throughout the ISM. In this work, we perform a census of the PAH heating–gas ionization connection using ∼700,000 independent pixels that probe scales of 40–150 pc in 19 nearby star-forming galaxies from the PHANGS survey. We find a universal relation between

log

PAH(11.3 μm/7.7 μm) and

log

([S ii]/Hα) with a slope of ∼0.2 and a scatter of ∼0.025 dex. The only exception is a group of anomalous pixels that show unusually high (11.3 μm/7.7 μm) PAH ratios in regions with old stellar populations and high starlight-to-dust emission ratios. Their mid-infrared spectra resemble those of elliptical galaxies. Active galactic nucleus hosts show modestly steeper slopes, with a ∼​​​​​​10% increase in PAH(11.3 μm/7.7 μm) in the diffuse gas on kiloparsec scales. This universal relation implies an emerging simplicity in the complex ISM, with a sequence that is driven by a single varying property: the spectral shape of the interstellar radiation field. This suggests that other properties, such as gas-phase abundances, gas ionization parameter, and grain charge distribution, are relatively uniform in all but specific cases.

Published: January 2025

Abstract
Mass (M) and luminosity (L) are fundamental parameters of stars but can only be measured indirectly. Typically, effective temperature (T
eff), surface gravity (

log

g

), and metallicity ([M/H]) are derived from stellar spectra, then M, L, and stellar age (t) can be obtained by interpolating in the grid of stellar evolutionary models. In this paper, we use random forest in combination with the evolutionary grid from PARSEC 1.2S to determine M, L, t, and initial mass (M
i) for early-type main-sequence stars (T
eff ≥ 7000 K) as identified from the LAMOST survey. The convex hull algorithm is employed to select the main-sequence stars. The results demonstrate that the prediction precision is 32% and 9% for L and M, respectively, which is comparable to that achieved by fitting evolutionary tracks. Furthermore, the predicted L also aligns with Gaia’s observations, with a relative difference of 36%. The prediction for t is relatively less accurate, indicating a difference of 0.44 Gyr for two components in wide binaries. This discrepancy is due to the inconsistent metallicity measurements. For the two sets of atmospheric parameters we used, the relative differences in L, M, t, and M
i are 29%, 7%, 36%, and 7%, respectively. The influence of metallicity on these parameters is analyzed, with the conclusion that metallicity has the greatest impact on t. Consequently, two catalogs are presented, which could be useful for studying stellar populations such as the luminosity function and initial mass function of early-type stars.

Abstract
We present a new photometric pipeline for the detection of pre-supernova (pre-SN) emission in the Young Supernova Experiment (YSE) sky survey. The method described is applied to SN 2020tlf, a type II SN with precursor emission in the last ~100 days before first light. We re-analyze the YSE griz-band light curves of SN 2020tlf and provide revised pre-explosion photometry that includes a robust list of confident detection and limiting magnitudes. Compared to the results of W. V. Jacobson-Galán et al., this new analysis yields fewer total r/i/z-band pre-SN detections at phases >−100 days. Furthermore, we discourage the use of the blackbody modeling of the pre-explosion spectral energy distribution, the pre-SN bolometric light curve and the blackbody model parameters presented in W. V. Jacobson-Galán et al. Nevertheless, binned photometry of SN 2020tlf confirms a consistent progenitor luminosity of ~1040 erg s−1 before explosion.

Published: January 2025

Postoperative pseudomeningocele is a rare, but still existing, complication after spinal surgeries. It may be asymptomatic or presented with back pain, radicular pain or headaches. Many pseudomeningoceles resolve spontaneously, others require revision surgery with dural repair. We present a female patient who underwent duroplasty treatment for a massive postoperative lumbar pseudomeningocele measuring 22.57 cm in length after broad laminectomy. A 71-year-old female with previous thoracolumbar T10-L5 instrumentation surgery, underwent a L2-5 broad laminectomy due to severe canal stenosis at the L2-5 level. Intraoperatively, an accidental spotted durotomy occurred at the level of L4-5. Primary repair was not feasible, so artificial dura was placed. Postoperatively the patient presented with cerebrospinal fluid (CSF) leak, which was treated with external lumbar drain and bedrest. Three months later, our patient presented to our outpatient clinic with a large 15 cm long bulging mass at the surgical site without any neurological deficit. A lumbar CT scan was conducted and a gigantic lumbar pseudomeningocele of 22.57 cm length and 6.29 cm width from the level of T11 to S2 was observed. We performed a revision surgery with duroplasty and there was no recurrence of CSF leak or pseudomeningocele after 7 months follow-up.
Pseudomeningoceles are rare post-operative complications. Although treatment options are controversial, they should be recognized soon enough in order to avoid central nervous infections, neurological deficits and further comorbidities.

Here we describe the first detected VIM-2-producing representative of Pseudomonas putida group – Pseudomonas kurunegalensis from the largest Bulgarian hospital – St George University Hospital in Plovdiv.
A 59-year-old female patient with right-sided lung abscess was hospitalized in the Second Clinic of Thoracoabdominal Surgery. She was repeatedly treated for pulmonary infections. Punctate from the abscess cavity was taken for microbiological investigation. Identification process and antimicrobial susceptibility were performed by Vitek 2. The species group P. putida was confirmed with MALDI-TOF system and whole genome sequencing defined it as P. kurunegalensis. Antibiotic susceptibility testing revealed susceptibility only to tobramycin and colistin. All phenotypic tests for carbapenemase and metallo-beta-lactamase (MBL) production were positive. Multiplex PCR was performed to search for nine common carbapenemase encoding genes whereas the variable region of the integron was determined by DNA sequencing. Molecular assays confirmed the presence of blaVIM-2 located within a typical Class I integron including also an aacA29b aminoglycoside N(6’)-acetyltransferase casette.
Despite P. putida not being a common pathogen, it still could survive in hospital conditions causing difficult-to-treat infections and becoming a source of resistant genes, including MBL-encoding genes.
Evaluation of psychosocial work environment among healthcare professionals in cardiac care units
Authors: Raycheva Ralitsa , Pavlova Pavlina , Dimova Rositsa 
Published: January 2025

Introduction: Modern healthcare organizations and medical institutions depend on several factors, including the psychological environment as part of organizational culture. The psychological climate is multifaceted and difficult to quantify. The majority of scientific researchers agree that a good psychological climate supports teamwork, good communication, and a willingness to disclose errors and adverse events.
Aim: The objective of the study is to test a comprehensive and theory-based psychosocial work environment questionnaire and analyze the psychosocial climate among healthcare professionals in cardiac care units.
Material and methods: A survey-based cross-sectional study was done from November 2022 to March 2023 to analyze the psychological climate of cardiac ward professionals in South-Central Bulgarian hospitals. The study used the Bulgarian version of Koys and DeCotiis’ Inductive Measures of Psychological Climate (IMPC) questionnaire.
Results: The survey included 273 participants, 75.1% of whom were women (n=205). The respondents’ median age was 46, ranging from 35 to 54. They included 35.2% (n=96) with over 21 years of hospital experience. The highest proportion of in-hospital experience in a present hospital facility / present hospital unit was in the category 1 to 5 years – 27.5% (n=74) / 27.5% (n=74). The respondents were mostly registered nurses (40.3%, n=110). Specialist doctors were second at 23.8% (n=65), followed by paramedics at 14.7% (n=40), fellow doctors at 11.7% (n=32), and technical/medical personnel at 7.3% (n=20). Our study defines the psychological climate in cardiac units as having low pressure, moderate autonomy, recognition, and innovation, and high levels of trust, cohesion, support, and fairness.
Conclusion: The study focused on cardiac units, necessitating tailored approaches to address concerns across other wards. Establishing transparent and secure healthcare cultures, valuing employee input, and improving the psychological environment requires stakeholder collaboration.
