Molecular Profiling of Sinonasal Adenoid Cystic Carcinoma: Canonical and Noncanonical Gene Fusions and Mutation.

Adenoid cystic carcinomas (AdCC) of salivary gland origin have long been categorized as fusion-defined carcinomas owing to the almost universal presence of the gene fusion MYB::NFIB, or less commonly MYBL1::NFIB. Sinonasal AdCC is an aggressive salivary gland malignancy with no effective systemic therapy. Therefore, it is urgent to search for potentially targetable genetic alterations associated with AdCC.

Rapidly spreading with OXA-48-like carbapenemases.

(mostly , ) with OXA-48-like carbapenemases (e.g., OXA-48, -181, -232, -244) are undermining the global efficiency of carbapenem therapy.

Biological activation of Fenton reaction in polymeric nanoreactors driven by ferrocene-containing membranes: a microenvironment dependent study.

Nanocatalytic medicine for treating cancer requires effective, versatile and novel tools and approaches to significantly improve the therapeutic efficiency for the interactions of (non-)enzymatic reactions. However, it is necessary to develop (non-)enzymatic nanotechnologies capable of selectively killing tumour cells without harming normal cells. Their therapeutic characteristics should be the adaption of tumours' extra- and intracellular environment to being specifically active.

Phase field simulations of thermal annealing for all-small molecule organic solar cells.

Interest in organic solar cells (OSCs) is constantly rising in the field of photovoltaic devices. The device performance relies on the bulk heterojunction (BHJ) nanomorphology, which develops during the drying process and additional post-treatment. This work investigates the effect of thermal annealing (TA) on the all-small molecule DRCN5T:PCBM blend with phase field simulations.

Cyclic Voltarefractometry of Single TiO Nanoparticles in Large Ensembles in Nonaqueous Electrolyte.

Single nanoparticle (NP) cyclic voltarefractometry (CVR), realized as wide-field surface plasmon resonance microscopy (SPRM) in combination with potential cycling, has been proposed and applied to the in situ study of TiO NPs. Electrochemical activity of TiO is mainly observed outside the electrochemical stability window of water. Therefore, the response of individual anatase (a-TiO) and rutile (r-TiO) NPs adsorbed on a gold layer was studied in 0.

Diverse reactivity of a cationic N-heterocyclic phosphenium complex towards anionic substrates - substitution reduction.

A cationic N-heterocyclic phosphenium (NHP) iron tetracarbonyl complex was synthesised from the free cation and its behaviour towards various anionic reactants studied. Reactions with fluoride, chloride, and hydride sources proceeded under attachment of the anion at phosphorus to yield Fe(CO)-complexes of neutral diazaphospholenes, while bromide and iodide reacted under addition of the anion at the metal and decarbonylation to yield NHP iron halides. Reactions with amides and organometallics were unselective.

Kinematics and directionality of body turning in water striders (Gerris argentatus) on the water surface.

Water striders inhabit the elastic surface tension film of water, sharing their environment with other aquatic organisms. Their survival relies heavily on swift maneuverability and navigation around floating obstacles, which aids in the exploration of their habitat and in escaping from potential threats. Their high agility is strongly based on the ability to execute precise turns, enabling effective directional control.

Silanediol-Bay-Bridge Rigidified Axially Chiral Perylene Bisimide.

Chiral organic molecules with a complementing π-structure are highly desired to obtain materials with good semiconducting properties and pronounced chirality effects in the visible region. Herein, we introduce a novel design strategy to achieve an axially chiral and rigid perylene bisimide (PBI) dye by attaching the chirality-inducing 2,2'-biphenoxy moiety at one side of the bay area and the rigidity-inducing di--butylsilanediol bridge on the other side. This yielded a new bay-functionalized PBI derivative carrying the combination of a highly rigid and, simultaneously, an axially chiral perylene core.

An untargeted metabolomics approach to evaluate enzymatically deconjugated steroids and intact steroid conjugates in urine as diagnostic biomarkers for adrenal tumors.

Objectives: Urinary steroid profiling after hydrolysis of conjugates is an emerging tool to differentiate aggressive adrenocortical carcinomas (ACC) from benign adrenocortical adenomas (ACA). However, the shortcomings of deconjugation are the lack of standardized and fully validated hydrolysis protocols and the loss of information about the originally conjugated form of the steroids. This study aimed to evaluate the quality of the deconjugation process and investigate novel diagnostic biomarkers in urine without enzymatic hydrolysis.

Serially quantifying TERT rearrangement breakpoints in circulating tumor DNA enables minimal residual disease monitoring in patients with neuroblastoma.

Telomerase is reactivated by genomic TERT rearrangements in ~30% of diagnosed high-risk neuroblastomas. Dismal patient prognosis results if the RAS/MAPK/ALK signaling transduction network also harbors mutations. We present a liquid biopsy-based monitoring strategy for this particularly vulnerable pediatric patient subgroup, for whom real-time molecular diagnostic tools are limited to date.

SARS-CoV-2 Productively Infects Human Hepatocytes and Induces Cell Death.

SARS-CoV-2 infection is accompanied by elevated liver enzymes, and patients with pre-existing liver conditions experience more severe disease. While it was known that SARS-CoV-2 infects human hepatocytes, our study determines the mechanism of infection, demonstrates viral replication and spread, and highlights direct hepatocyte damage. Viral replication was readily detectable upon infection of primary human hepatocytes and hepatoma cells with the ancestral SARS-CoV-2, Delta, and Omicron variants.

Adrenal gland size in fetuses with congenital heart disease.

Objectives: The aim of this study was to compare the adrenal gland size of fetuses with congenital heart diseases (CHD) and normal fetuses.

Methods: In this cross-sectional prospective study we measured the fetal adrenal gland size (total width, cortex width, medulla width, adrenal gland ratio of total width divided by medulla width) in 62 fetuses with CHD and 62 gestational-age-matched controls between 20 + 0 and 39 + 3 weeks of gestation. First, we clustered three CHD subgroups: CHD group_1 with a normal outflow tract (n=7), CHD group_2 with an altered outflow tract and anterograde flow in the ascending aorta (n=39) and CHD group_3 with an altered outflow tract and retrograde flow in the ascending aorta (n=16).

Influence of nonequilibrium vibrational dynamics on spin selectivity in chiral molecular junctions.

We explore the role of molecular vibrations in the chirality-induced spin selectivity (CISS) effect in the context of charge transport through a molecular nanojunction. We employ a mixed quantum-classical approach that combines Ehrenfest dynamics for molecular vibrations with the hierarchical equations of motion method for the electronic degrees of freedom. This approach treats the molecular vibrations in a nonequilibrium manner, which is crucial for the dynamics of molecular nanojunctions.

Purpose: This study explores the potential interaction of brolucizumab with platelets and its effects on platelet activation and reactivity, crucial in retinal vasculitis and retinal vascular occlusion. Safety concerns remain of interest, although brolucizumab showed superior retinal efficacy and reduced injection frequency compared to other licensed anti-VEGF agents.

Methods: Resting and activated platelets of healthy volunteers were pretreated with brolucizumab at the following concentrations 0.

Expanding the immune-related targetome of miR-155-5p by integrating time-resolved RNA patterns into miRNA target prediction.

The lack of a sufficient number of validated miRNA targets severely hampers the understanding of their biological function. Even for the well-studied miR-155-5p, there are only 239 experimentally validated targets out of 42,554 predicted targets. For a more complete assessment of the immune-related miR-155 targetome, we used an inverse correlation of time-resolved mRNA profiles and miR-155-5p expression of early CD4+ T cell activation to predict immune-related target genes.

The development of versatile strategies for preparing functional carbon materials is essential for advancing a wide range of applications in materials science. Precursor design plays a pivotal role in governing the chemistry and structure of carbon materials for target applications. In this work, we report the synthesis of Meldrum's acid derivatives through Knoevenagel condensation with aromatic heterocycles such as pyrrole, furan, and thiophene, which serve as precursors for carbonaceous materials with tailored chemical and electronic properties.

Orthorhombic Covalent Organic Frameworks with fmj Topology as Photocatalyst for Hydrogen Evolution.

Three-dimensional covalent organic frameworks (3D COFs), a class of highly porous crystalline polymers, have exhibited great potentials in many applications. However, the reported topologies of 3D COFs have been limited to high-symmetry crystal systems, which significantly hindered the development of such functional materials. Herein, we demonstrate the first construction of four highly crystalline orthorhombic 3D COFs with an unprecedented fmj topology, based on judiciously choosing rotatable monomers.

Body Composition in Cholangiocarcinoma Affects Immune Cell Populations in the Tumor and Normal Liver Parenchyma.

Background: Due to malnutrition and tumor cachexia, body composition (BC) is frequently altered and known to adversely affect short- and long-term results in patients with cholangiocarcinoma (CCA). Here, we explored immune cell populations in the tumor and liver of CCA patients with respect to BC.

Methods: A cohort of 96 patients who underwent surgery for CCA was investigated by multiplexed immunofluorescence (MIF) techniques with computer-based analysis on whole-tissue slide scans to quantify and characterize immune cells in normal liver and tumor regions.

The uses of right heart catheterization in cardio-pulmonary disease: State-of-the-art.

The right heart catheterization (RHC) remains an important diagnostic tool for a spectrum of cardiovascular disease processes including pulmonary hypertension (PH), shock, valvular heart disease, and unexplained dyspnea. While it gained widespread utilization after its introduction, the role of the RHC has evolved to provide valuable information for the management of advanced therapies in heart failure (HF) and cardiogenic shock (CS) to name a few. In this review, we provide a comprehensive overview on the indications, utilization, complications, interpretation, and calculations associated with RHC.
