Conjugation of Short-Chain Fatty Acids to Bicyclic-Amines for Analysis by Liquid Chromatography Tandem Mass Spectroscopy.

Conjugation of short-chain fatty acids (SDFAs) to amines containing ring structures allows for better measurement by liquid chromatography tandem mass spectroscopy (LC-MS/MS). However, collision-induced dissociation (CID) results in breaking the conjugate back to the original SCFA and amine. We therefore set out to find an amine that would remain on the SCFA after CID and create a unique daughter for selectivity of measurement.

Hydrogen-Bonded Di(hydroperoxy)alkane Adducts of the Type CyP=O·(HOO)CHR (R = Alkyl).

Five representatives of a novel type of di(hydroperoxy)alkane adducts of phosphine oxides have been synthesized and fully characterized, including their solubility in organic solvents. The phosphine oxide CyPO () has been used in combination with the corresponding aldehydes to create the adducts CyPO·(HOO)CHCH (), CyPO·(HOO)CHCHCH (), CyPO·(HOO)CH(CH)CH (), CyPO·(HOO)CH(CH)CH (), and CyPO·(HOO)CH(CH)CH (). All adducts crystallize easily and contain the peroxide and phosphine oxide hydrogen-bonded in 1:1 ratios.

Genetic Algorithm-Enhanced Direct Method in Protein Crystallography.

Direct methods based on iterative projection algorithms can determine protein crystal structures directly from X-ray diffraction data without prior structural information. However, traditional direct methods often converge to local minima during electron density iteration, leading to reconstruction failure. Here, we present an enhanced direct method incorporating genetic algorithms for electron density modification in real space.

Modeling, Design, and Laboratory Testing of a Passive Friction Seismic Metamaterial Base Isolator (PFSMBI).

This paper focuses on the theoretical and analytical modeling of a novel seismic isolator termed the Passive Friction Mechanical Metamaterial Seismic Isolator (PFSMBI) system, which is designed for seismic hazard mitigation in multi-story buildings. The PFSMBI system consists of a lattice structure composed of a series of identical small cells interconnected by layers made of viscoelastic materials. The main function of the lattice is to shift the fundamental natural frequency of the building away from the dominant frequency of earthquake excitations by creating low-frequency bandgaps (FBGs) below 20 Hz.

This study aims to analyze outcomes of hysterectomy as second-trimester active management (AM) versus cesarean hysterectomy as expectant management (EM) in cases of PAS with intraoperative and postoperative outcomes. This study is a retrospective case-control study of patients with a pathology-confirmed diagnosis of PAS managed at a single center over 16 years (2005-2020).

Research Progress and Clinical Translation Potential of Coronary Atherosclerosis Diagnostic Markers from a Genomic Perspective.

Coronary atherosclerosis (CAD) is characterized by arterial intima lipid deposition, chronic inflammation, and fibrous tissue proliferation, leading to arterial wall thickening and lumen narrowing. As the primary cause of coronary heart disease and acute coronary syndrome, CAD significantly impacts global health. Recent genetic studies have demonstrated CAD's polygenic and multifactorial nature, providing molecular insights for early diagnosis and risk assessment.

Management and Outcome of Invasive Clindamycin-Resistant MRSA Community-Associated Infections in Children.

Background: Clindamycin resistance among community-associated methicillin-resistant (CA-MRSA) complicates the management of a challenging infection. Little data exist to guide clinicians in the management of invasive clindamycin-resistant CA-MRSA infections in children and studies using oral regimens such as trimethoprim-sulfamethoxazole (TMP-SMX) and linezolid for treatment of these infections are limited. We sought to reevaluate antibiotic management among invasive CA-MRSA at a tertiary children's hospital.

Age-Related Changes in Gut Health and Behavioral Biomarkers in a Beagle Dog Population.

A Review of Neoadjuvant Therapy for Localized and Locally Advanced Renal Cell Carcinoma.

The introduction of vascular endothelial growth factor receptor-tyrosine kinases (VEGFR-TKIs) and immune checkpoint inhibitors (IOs) have drastically altered the treatment landscape for kidney cancer, with doublet combination immunotherapy (IO/IO or IO/VEGFR-TKI) now set as the standard front-line treatment for advanced renal cell carcinoma (RCC). However, the roles of VEGFR-TKIs and IOs in the neoadjuvant setting for locoregional/locally advanced RCC remain undefined, where the goals may be primary tumor downsizing/downstaging and potentially eradicating micrometastatic disease. This review will examine VEGFR-TKI monotherapy, IO monotherapy, and VEGFR-TKI/IO combination regimens in a preoperative setting with a focus on the efficacy, toxicity, surgical, and long-term implications.

The Clinical Utility of a Next-Generation Sequencing-Based Approach to Detecting Circulating HPV DNA in Patients with Advanced Anal Cancer.

Background: To extend the practicality of liquid biopsy beyond the historical HPV circulating tumor DNA (ctDNA) assays, we evaluated the clinical relevance of a novel next-generation sequencing HPV ctDNA assay in patients with locally advanced and metastatic squamous cell cancer of the anal canal (mSCCA).

Methods: ctDNA isolated from the plasma of patients with mSCCA was sequenced using a 1.4 Mb hybrid-capture target-enrichment panel covering the whole genome sequences of all 193 HPV types.

Activation of Genes by Nuclear Receptor/Specificity Protein (Sp) Interactions in Cancer.

The human nuclear receptor (NR) superfamily consists of 48 genes that are ligand-activated transcription factors that play a key role in maintaining cellular homeostasis and in pathophysiology. NRs are important drug targets for both cancer and non-cancer endpoints as ligands for these receptors can act as agonists, antagonists or inverse agonists to modulate gene expression. With two exceptions, the classical mechanism of action of NRs involves their interactions as monomers, dimers or heterodimers with their cognate response elements (cis-elements) in target gene promoters.

DNA Methylation Profile in Buffy Coat Identifies Methylation Differences Between Cirrhosis with and Without Hepatocellular Carcinoma.

Background/objectives: Cirrhosis is the precursor to most cases of hepatocellular carcinoma (HCC). Understanding the mechanisms leading to the transition from cirrhosis to HCC and identifying key biomarkers is crucial to developing effective screening strategies and reducing HCC-related mortality. DNA methylation is associated with gene inactivation and plays an important role in physiological and pathological processes; however, its role in cirrhosis progression to HCC is unknown.

Spatial Distribution of Tumor Cells in Clear Cell Renal Cell Carcinoma Is Associated with Metastasis and a Matrisome Gene Expression Signature.

Predicting the behavior of clear cell renal cell carcinoma (ccRCC) is challenging using standard-of-care histopathologic examination. Indeed, pathologic RCC tumor grading, based on nuclear morphology, performs poorly in predicting outcomes of patients with International Society of Urological Pathology/World Health Organization grade 2 and 3 tumors, which account for most ccRCCs. We applied spatial point process modeling of H&E-stained images of patients with grade 2 and grade 3 ccRCCs ( = 72) to find optimum separation into two groups.

A Multidisciplinary Approach to Diagnosing Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN): Practical Recommendations and Insights from Countries of the Gulf Cooperation Council.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive orphan hematopoietic malignancy characterized by cutaneous and systemic hematologic involvement. BPDCN is frequently misidentified, but early, accurate diagnosis is critical to extending patient survival using tagraxofusp, a first-in-class CD123-targeted therapy, and increasing their chances of receiving a potentially curative stem cell transplantation. Cases of BPDCN in countries of the Gulf Cooperation Council are lower than the extrapolated incidence from other geographic locations due to lack of awareness of key diagnostic features, lack of consensus on the minimal phenotype for diagnosis, and lack of local immunohistochemistry testing facilities, contributing to underdiagnosis in this region.
