Legg-Calvé-Perthes Disease (LCPD) is a condition marked by temporary blood flow disruption to the proximal femur, commonly afflicting children aged 15 and younger. The etiology of the disease is often idiopathic and involves the development of avascular necrosis of the femoral head, subsequently leading to bone weakening and deformity. Obesity exacerbates LCPD, correlating with delayed diagnosis, increased disease severity, and bilateral involvement.

Background: Neighborhood characteristics serve as risk factors for metabolic syndrome (MetS). However, the intermediary factors linking this relationship remain understudied. Thus, we investigated the sex-specific mediating role of C-reactive protein, physical activity (PA), and perceived stress in the associations of perceived neighborhood social environment (PNSE) with MetS severity among Black adults.

Bis-1,2,4-triazine ligands are amongst the most promising soft N-donor ligands for the partitioning of trivalent actinides from trivalent lanthanides; a key separation proposed in the future reprocessing of spent nuclear fuels. In an effort to improve the extraction properties of these benchmark ligands, we propose herein a general ligand design approach that is inspired by the field of drug discovery, and we apply it to a new class of ligands in which the bidentate 3-(2-pyridyl)-1,2,4-triazine unit of the benchmark ligands is replaced by a bidentate 1,2,4-triazine-3-carboxamide unit. A series of nine novel ligands were synthesized by reactions of readily available ethyl 1,2,4-triazine-3-carboxylate building blocks with different polyamine cores and evaluated for their ability to extract and separate Am(III) and Cm(III) from Eu(III).

We have shown that palladium-catalyzed cascade processes provide modular access to rigid quinoline-containing tetracyclic amines. This modular approach enables fine-tuning of the through-space charge transfer (TSCT) state formation between the lone pair localized on the nitrogen atom in the cage moiety and the quinoline moiety by variation of both the intramolecular -aryl distance and quinoline substitution. Decreasing this -aryl distance enhances the formation of the TSCT species, giving control over the emission color and photoluminescence quantum yield.

Article Synopsis
  • Many care management programs for chronic lung disease fail to effectively reduce hospitalizations because they don't address the specific mechanisms causing them.
  • The study examined the experiences of 22 patients with chronic lung disease who were hospitalized, focusing on common underlying issues that led to their acute exacerbations.
  • Key findings included factors like difficulty managing symptoms at home, barriers to accessing healthcare, ongoing functional limitations, and mental health issues, which often existed long before hospitalization.

The G haplotype is a group of co-inherited single nucleotide variants in the F5 gene that reduce venous thromboembolism (VTE) risk. Although 7% of the population is homozygous for the G haplotype (F5-G/G), the underlying mechanism of VTE protection is poorly understood. Using RNA sequencing data from 4651 blood donors in the INTERVAL study, we detected a rare excision event at the factor V (FV)-short splice sites in 5% of F5-G/Gs carriers as compared with 2.

As of 2024, SARS-CoV-2 continues to propagate and drift as an endemic virus, impacting healthcare for years. The largest sequencing initiative for any species was initiated to combat the virus, tracking changes over time at a full virus base-pair resolution. The SARS-CoV-2 sequencing represents a unique opportunity to understand selective pressures and viral evolution but requires cross-disciplinary approaches from epidemiology to functional protein biology.

A phenanthroline-type ligand containing an annealed 1,2,4-triazine ring was used to prepare novel Ir(III) complexes 3 and 4. The complexes are non-luminescent but show luminogenic behaviour following the inverse electron demand Diels-Alder (IEDDA) reaction with bicyclononyne (BCN) derivatives. It was observed that the complexes react with BCN-C10 faster than the corresponding free ligands.

Freshwater turtles exhibit temporary threshold shifts (TTS) when exposed to broadband sound, but whether frequency-restricted narrowband noise induces TTS was unknown. Underwater TTS was investigated in two freshwater turtle species (Emydidae) following exposures to 16-octave narrowband noise (155-172 dB re 1 μPa2 s). While shifts occurred in all turtles at the noise center frequency (400 Hz), there were more instances of TTS and greater shift magnitudes at 12 octave above the center frequency, despite considerably lower received levels.

Few prospective studies examine multilevel resilience resources and psychosocial factors in relation to cardiovascular health and disease. Recent research indicates that resilience resources are associated with a reduction in the incidence of cardiovascular disease-related events, but few studies have examined this relationship across different racial/ethnic populations or in large cohorts. Harmonization may address these limitations because it allows data from several cohorts to be analyzed together, potentially increasing sample size and in turn power overall and in minority populations.

Obesity and poverty disproportionally affect African American persons. Epigenetic mechanisms could partially explain the association between socioeconomic disadvantage and body mass index (BMI). We examined the extent to which epigenetic mechanisms mediate the effect of socioeconomic status (SES) on BMI.

Race play, the act of making explicit overtures to race, racial differences, or political racial dynamics within the context of a kink or BDSM (bondage dominance/submission, sadism/masochism) can be a contentious topic among scholars and members of alternative sexuality communities. In the current study, we explored how individuals' ideologies about race and sex are associated with their opinions of race play. Two-hundred thirty-four participants recruited through sex-positive and BDSM community spaces between January and June of 2021 completed measures of color-blind racial ideology and sexual comfort as assessments of critical consciousness and sex-positive values.

Unlabelled: Programmed cell death mechanisms are important for the regulation of tumor development and progression. Evasion of and resistance to apoptosis are significant factors in tumorigenesis and drug resistance. Bypassing apoptotic pathways and eliciting another form of regulated cell death, namely necroptosis, an immunogenic cell death (ICD), may override apoptotic resistance.
