Bromodomain and extra-terminal (BET) proteins are critical regulators of gene transcription, as they recognize acetylated lysine residues. The BD1 bromodomain of BRD4, a member of the BET family, has emerged as a promising therapeutic target for various diseases. This study aimed to develop and evaluate a novel C-11 labeled PET radiotracer, [C]YL10, for imaging the BD1 bromodomain of BRD4 in vivo.

Fructose consumption has increased considerably over the past five decades, largely due to the widespread use of high-fructose corn syrup as a sweetener. It has been proposed that fructose promotes the growth of some tumours directly by serving as a fuel. Here we show that fructose supplementation enhances tumour growth in animal models of melanoma, breast cancer and cervical cancer without causing weight gain or insulin resistance.

This investigation aims to develop an angular stiffness sensor intended for measuring dental implant stability in bone. The sensor hardware included a tiny eccentric motor and an accelerometer to measure a flex constant of an implant with its abutment. The sensor software included a mechanics-based model to convert the flex constant to angular stiffness at the implant/abutment junction to indicate the stability.

Objective: To investigate the neural mechanisms underlying working memory (WM) deficits in children with ADHD.

Method: WM was compared between thirty-four children with ADHD and thirty-four matched controls using neuropsychological tests, spatial and verbal versions of modified delayed matching-to-sample (DMTS) tasks, and the event-related potential technique.

Results: Children with ADHD demonstrated poor behavioral performance, delayed P3 latencies in high-load spatial modified DMTS tasks during encoding, and delayed P2 and N2 latencies during retrieval in spatial modified DMTS tasks.

Despite decades of antibody research, it remains challenging to predict the specificity of an antibody solely based on its sequence. Two major obstacles are the lack of appropriate models and the inaccessibility of datasets for model training. In this study, we curated >5,000 influenza hemagglutinin (HA) antibodies by mining research publications and patents, which revealed many distinct sequence features between antibodies to HA head and stem domains.

Context: Neuropathy and fracture are prevalent complications of type 1 diabetes (T1D). Although correlated in the clinical literature, it remains unknown whether neuropathy contributes to the initiation of bone loss at the earliest stages of disease.

Methods: We performed a single-center, cross-sectional study to quantify parameters of nerve and bone health in adolescent girls with T1D (n=21) and associated controls (n=12).

The receptor-binding site of influenza A virus hemagglutinin partially overlaps with major antigenic sites and constantly evolves. In this study, we observe that mutations G186D and D190N in the hemagglutinin receptor-binding site have coevolved in two recent human H3N2 clades. X-ray crystallography results show that these mutations coordinately drive the evolution of the hemagglutinin receptor binding mode.

Aims: Advanced chronic liver disease and advanced chronic liver disease-related ascites have a high mortality. The pharmacological treatment of ascites and fluid overload has changed little over time. Empagliflozin, a sodium-glucose cotransporter type 2 inhibitor is an untested potential novel treatment in cirrhosis, as it has survival benefits in heart failure, which has similar pathophysiological fluid overload mechanisms.

Article Synopsis
  • HLA-B27, a significant risk factor for spondyloarthritis (SpA), may involve impaired protein folding and subsequent inflammation pathways, particularly IL-23 induced by endoplasmic reticulum (ER) stress.
  • Researchers studied the effect of deleting the CHOP transcription factor, which influences ER stress-related IL-23 production, on gut inflammation in genetically modified rats (HLA-B27-Tg).
  • Findings revealed that removing CHOP did not reduce gut inflammation; instead, it increased other pro-inflammatory markers, suggesting that CHOP might actually help mitigate severe gut inflammation linked to HLA-B27.

Objective: To compare early pulmonary function tests (PFTs) in neonates with critical congenital heart disease (CHD) compared to a historical reference group.

Design: Infants ≥ 37 weeks gestation with critical CHD were studied within the first few days of life, prior to cardiac surgery, and compared to data from a published reference group of healthy term neonates without CHD, studied at the same institution. Passive respiratory resistance (Rrs) and compliance (Crs) were measured with the single breath occlusion technique following specific acceptance criteria.

Purpose: To investigate how well an implant stability quotient (ISQ) represents resonance frequency.

Materials And Methods: Benchtop experiments on standardized samples that replicated a mandibular premolar site were conducted to correlate an ISQ value and a resonance frequency to synthetic bone density and an incremental insertion torque; then, a frequency spectrum analysis was performed to check the validity of the resonance frequency analysis (RFA). Brånemark Mk III implants (4 × 11.

Objective: The ideal type of hospital to care for adult congenital heart disease (ACHD) patients is not well known. Hospital competitiveness, clinical volume and market structure can influence clinical outcomes. We sought to understand how hospital competitiveness affects clinical outcomes in ACHD patients in the era prior to the Adult Congenital Heart Association accreditation program.

Patients with diabetes have a high risk of developing skeletal diseases accompanied by diabetic peripheral neuropathy (DPN). In this study, we isolated the role of DPN in skeletal disease with global and conditional knockout models of sterile-α and TIR-motif-containing protein-1 (Sarm1). SARM1, an NADase highly expressed in the nervous system, regulates axon degeneration upon a range of insults, including DPN.

Neural radiance field (NeRF) has emerged as a versatile scene representation. However, it is still unintuitive to edit a pretrained NeRF because the network parameters and the scene appearance are often not explicitly associated. In this article, we introduce the first framework that enables users to retouch undesired regions in a pretrained NeRF scene without accessing any training data and category-specific data prior.

The ability of the human immune system to generate antibodies to any given antigen can be strongly influenced by immunoglobulin V-gene allelic polymorphisms. However, previous studies have provided only limited examples. Therefore, the prevalence of this phenomenon has been unclear.

Subsequently to the publication of the above paper, an interested reader drew to the authors' attention that a pair of the data panels showing the results of Transwell invasion assays (specifically, the 'C4‑2 / shCON' and the PC‑3 / CON panels) featured in Fig. 3F on p. 927 contained overlapping sections, such that data that were intended to show the results from differently performed experiments appeared to have been derived from the same original source.

Objective: Obesity and nutrient oversupply increase mammalian target of rapamycin (mTOR) signaling in multiple cell types and organs, contributing to the onset of insulin resistance and complications of metabolic disease. However, it remains unclear when and where mTOR activation mediates these effects, limiting options for therapeutic intervention. The objective of this study was to isolate the role of constitutive mTOR activation in Nav1.

Background: The Ross operation for aortic valve replacement continues to be a controversial option because of concerns related to late autograft dilation and progressive neo-aortic insufficiency. In 2005, the reinforced Ross procedure was described at our institution to address this problem. We aim to analyze the short and mid-term outcomes following this procedure.

Article Synopsis
  • The study investigates the effects of high temperatures on seven types of endodontic sealers to assess their surface features, chemical makeup, and thermal properties.
  • The research used advanced techniques like scanning calorimetry and thermogravimetric analysis, alongside microscopic methods, to analyze the sealers' responses to heat.
  • Results indicated that while AH Plus and GuttaFlow BioSeal remained stable under thermal stress, five other sealers showed significant degradation, implying that the first two may be preferable for thermal endodontic procedures.
