Water stable colloidal PVP coated spin crossover nanoparticles.

Stable aqueous dispersions of spin-crossover (SCO) doped [Fe(Htrz)(trz)](BF) nanoparticles (NPs) were prepared by using water-soluble polyvinylpyrrolidone (PVP) as protecting polymer. The metal or ligand substitution percentage regulated the ultra-small size and morphology of the NPs. At the same time, the colloidal dispersions showed a complete conversion of the LS state to the HS state of the Fe ion.

Discovery of a new soft-bodied click-beetle genus from Namibia with a unique morphology leads to a modified diagnosis of Drilini (Coleoptera, Elateridae).

Drilini are soft-bodied predatory click beetles with incompletely metamorphosed females. Approximately 150 described species are distributed in the Afrotropical, Palaearctic and Oriental realms, with the highest diversity known from sub-Saharan Africa. In this study, we describe from Namibia which brings the total number of genera in Drilini to 16.

Strong anticancer activity of copper(ii) and zinc(ii) complexes containing naturally occurring lapachol: cellular effects in ovarian A2780 cells.

Copper(ii) and zinc(ii) complexes with lapachol (HLap) of the composition [M(Lap)(N-N)] and [Cu(Lap)(HO)(terpy)]NO (4), where M = Cu (1-3) or Zn (for 5-7), and N-N stands for bathophenanthroline (1 and 5), 5-methyl-1,10-phenanthroline (2 and 6), 2,2'-bipyridine (3), 2,2';6',2''-terpyridine (terpy, 4) and 1,10-phenanthroline (7), were synthesised and characterised. Complexes 1-5 revealed strong antiproliferative effects against A2780, A2780R, MCF-7, PC-3, A549 and HOS human cancer lines and MRC-5 normal cells, with IC values above 0.5 μM, and reasonable selectivity index (SI), with SI > 3.

Relative inhibitory activities of newly developed diazabicyclooctanes, boronic acid derivatives, and penicillin-based sulfone β-lactamase inhibitors against broad-spectrum AmpC β-lactamases.

The relative inhibitory activities of diazabicyclooctanes (avibactam, relebactam, zidebactam, nacubactam, durlobactam), boronic acid derivatives (vaborbactam, taniborbactam, xeruborbactam), and penicillin-based sulfone derivative enmetazobactam were evaluated against several intrinsic and acquired class C β-lactamases. By contrast to vaborbactam and enmetazobactam, taniborbactam, xeruborbactam, and all diazabicyclooctanes demonstrated effective activities against most AmpC enzymes. Notably, durlobactam exhibited the most pronounced inhibitory effect.

A Longitudinal Investigation on the Reciprocal Relationship of Problematic Smartphone Use with Bedtime Procrastination, Sleep Quality, and Mental Health Among University Students.

Background: Problematic smartphone use (PSU) is linked to various mental health issues, but the relationship between PSU, bedtime procrastination, and mental health symptoms is unclear. Sleep factors related to PSU and its mental health effects have been understudied. This study explores the longitudinal associations between PSU, bedtime procrastination, sleep quality, and mental health in university students.

Social mechanisms behind the poor health of marginalized Roma: Novel insights and implications from four ethnographic studies in Slovakia.

Roma represent one of the largest ethnic groups facing marginalization worldwide. However, significant knowledge gaps persist regarding: A) the social mechanisms supporting health-endangering practices among Roma; B) the social mechanisms adversely affecting their use of health services; and C) the social determinants underlying both above pathways. To fill these gaps, we conducted a series of four explorative ethnographic studies spanning over ten years.

Psychodermatology in Hungary: Awareness and practice patterns of dermatologists.

Background: Psychodermatology is an interdisciplinary branch of medicine between psychiatry /psychology and dermatology.

Objectives: This study aimed to assess Hungarian dermatologists' awareness, practice patterns and attitudes towards psychodermatology.

Methods: A questionnaire-based survey was sent from October 2020 to June 2021 to 100 dermatologists (including residents in dermatology) in Hungary with a response rate of 51%.

Sucrose-responsive osmoregulation of plant cell size by a long non-coding RNA.

In plants, sugars are the key source of energy and metabolic building blocks. The systemic transport of sugars is essential for plant growth and morphogenesis. Plants evolved intricate molecular networks to effectively distribute sugars.

Differential Sources of Resistance from Against Three Races of pathovar (Brown, 1918) Morinière et al. 2020 Causing Bacterial Leaf Spot of Lettuce.

Bacterial leaf spot (BLS) of lettuce ( L.) is caused by the bacterium pv. which is hypothesized to have at least three races of the pathogen present in North America as defined by their differential resistance phenotypes in lettuce cultivars/accessions.

Outcome of patients with diffuse large B-cell lymphoma and testicular involvement - real world data.

Patients with testicular lymphoma are at an increased risk of central nervous system (CNS) disease. Optimal strategy for CNS relapse prevention is unknown. We analyzed treatment strategies, cumulative incidence of CNS relapse and prognosis in 229 patients with diffuse large B-cell lymphoma (DLBCL) and testicular involvement: 157 primary testicular lymphomas (PTL) in clinical stages IE/IIE and 72 patients in advanced stages (T-DLBCL) IIIE/IV.

The role of Fetuin-A and Leucine-rich α-2-glycoprotein in the diagnosis of prostate cancer - a pilot study.

Background: Prostate cancer (PC) is one of the most frequently diagnosed non-skin solid cancers and is a leading cause of cancer-related death and the incidence increasing. Early diagnosis of the disease improves the outcomes. There is an urgent need for new biomarkers with greater discriminative precision for diagnosis, risk-stratification and treatment.

Primary ventriculitis caused by Streptococcus intermedius - a rare case and challenge with uncertain clinical outcome. Case report.

Aims: To present a case of primary ventriculitis in a 53-year-old patient caused by Streptococcus intermedius, emphasizing the rarity of the condition and the challenges in achieving clinical improvement despite targeted therapy.

Methods: The patient underwent clinical evaluation, including CT and MRI imaging, as well as CSF analysis. Empirical antibiotic therapy was initiated with cefotaxime and metronidazole, followed by targeted therapy based on CSF culture results.

Percutaneous transthoracic needle biopsy of lung lesions is a safe method associated with a very low risk of pleural recurrence.

Aim: Percutaneous transthoracic needle biopsy (PTNB), an alternative to bronchoscopic confirmation of lung lesions, is today being associated with a risk of pneumothorax and hemorrhage. Further, there are no data on the possible risk of malignant disease spreading to the pleura at the site of the PTNB. Previous studies have dealt with this risk in stage I non-small cell lung cancer only.
