Silicone Fiducial Markers Improve Precision in Uveal Melanoma Radiation Therapy.

: Accurate target definition, treatment planning and delivery increases local tumor control for radiotherapy by minimizing collateral damage. To achieve this goal for uveal melanoma (UM), tantalum fiducial markers (TFMs) were previously introduced in proton and photon beam radiotherapy. However, TFMs cause pronounced scattering effects in imaging that make the delineation of small tumors difficult.

Association of Corticosteroid Inhaler Type with Saliva Microbiome in Moderate-to-Severe Pediatric Asthma.

: Metered-dose inhalers (MDIs) and dry powder inhalers (DPIs) are common inhaled corticosteroid (ICS) inhaler devices. The difference in formulation and administration technique of these devices may influence oral cavity microbiota composition. We aimed to compare the saliva microbiome in children with moderate-to-severe asthma using ICS via MDIs versus DPIs.

Directed Evolution of AAV9 for Efficient Gene Expression in Cardiomyocytes and .

Adeno-associated viral (AAV) vectors are increasingly used for preclinical and clinical cardiac gene therapy approaches. However, gene transfer to cardiomyocytes poses a challenge due to differences between AAV serotypes in terms of expression efficiency and . For example, AAV9 vectors work well in rodent heart muscle cells but not in cultivated neonatal rat ventricular cardiomyocytes (NRVCMs), necessitating the use of AAV6 vectors for studies.

Williams-Beuren Syndrome and Epilepsy: A Retrospective Analysis of 589 Patients.

Although many reports have described the characteristics of Williams-Beuren syndrome, few specifically analyzed epilepsy in patients with Williams-Beuren syndrome. In this retrospective study, we map the prevalence, types, and prognosis of epileptic seizures in a large cohort of 589 patients with Williams-Beuren syndrome, as well as associations between deletions of the membrane-associated guanylate kinase inverted-2-gene (2 gene), which is associated with infantile spasms (IS), and epilepsy in patients with Williams-Beuren syndrome.Our findings indicate that the incidence of epilepsy in patients with Williams-Beuren syndrome is approximately 1.

Prevalence, antimicrobial susceptibility profiles and resistant gene identification of bovine subclinical mastitis pathogens in Bangladesh.

Subclinical mastitis (SCM), a silent threat in the dairy sector of Bangladesh poses a significant economic impact and serves as a potential source of infection for healthy cows, hindering efforts to achieve milk self-sufficiency. Despite the importance of this issue, limited research has been conducted on mastitis in Sylhet region of Bangladesh. This study aimed to investigate the molecular prevalence, antimicrobial susceptibility profile and resistant genes detection on pathogens ( and causing SCM.

Multi-environment field trials for wheat yield, stability and breeding progress in Germany.

Multi-environmental trials (MET) with temporal and spatial variance are crucial for understanding genotype-environment-management (GxExM) interactions in crops. Here, we present a MET dataset for winter wheat in Germany. The dataset encompasses MET spanning six years (2015-2020), six locations and nine crop management scenarios (consisting of combinations for three treatments, unbalanced in each location and year) comparing 228 cultivars released between 1963 and 2016, amounting to a total of 526,751 data points covering 24 traits.

Multiple Contrast Tests in the Presence of Partial Heteroskedasticity.

This paper proposes a general approach for handling multiple contrast tests for normally distributed data in the presence of partial heteroskedasticity. In contrast to the usual case of complete heteroskedasticity, the treatments belong to subgroups according to their variances. Treatments within these subgroups are homoskedastic, whereas treatments of different subgroups are heteroskedastic.

The North American Repository for Archaeological Isotopes.

Here, we present the North American Repository for Archaeological Isotopes (NARIA), the largest open-access compilation of previously reported isotopic measurements (n = 28,374) from bioarchaeological samples in North America (i.e., Canada, Greenland, Mexico, and the United States of America) covering a time-frame of more than 12,000 years.

Identification of Quantitative Trait Loci (QTLs) and candidate genes for trichome development in Brassica villosa using genetic, genomic, and transcriptomic approaches.

Brassica villosa is characterized by its dense hairiness and high resistance against the fungal pathogen Sclerotinia sclerotiorum. Information on the genetic and molecular mechanisms governing trichome development in B. villosa is rare.

Impact of coronary artery tortuosity on outcomes following stenting with newer-generation drug-eluting stents. An analysis of the randomized BIOFLOW trials.

Introduction And Objectives: Patients undergoing percutaneous coronary intervention in vessels with moderate-to-severe tortuosity are at higher risk of adverse outcomes, but data are scarce in the era of newer-generation stents. We compared outcomes following percutaneous coronary intervention in vessels with moderate-to-severe tortuosity using a bioresorbable-polymer sirolimus-eluting stent (BP-SES) vs a durable-polymer everolimus-eluting stent.

Methods: A total of 2350 patients from the BIOFLOW II, IV, and V randomized trials were stratified into 2 groups based on target-vessel tortuosity: none-to-mild and moderate-to-severe.

A structure-based analysis of the Kell blood group system.

Kell is one of the most complex blood group systems, with a highly polymorphic genetic background. Extensive allelic variations in the gene affect the encoded erythrocyte surface protein Kell. Genetic variants causing aberrant splicing, premature termination of protein translation, or specific amino acid exchanges lead to a variety of different phenotypes with altered Kell expression levels or changes in the antigenic properties of the Kell protein.

Quantitative flow ratio of the donor coronary artery supplying a chronic total occlusion territory.

Background: Coronary physiology to guide multi-vessel coronary intervention is associated with better outcome. In the presence of a coronary chronic total occlusion (CTO), hemodynamic evaluation of intermediate lesions in the donor coronary artery supplying a CTO territory still has limitations. We aim to evaluate implementing quantitative flow ratio (QFR) in assessing angiographically intermediate lesions of the main donor coronary artery supplying a CTO territory.

Evolution of sympatric host-specialized lineages of the fungal plant pathogen Zymoseptoria passerinii in natural ecosystems.

The barley disease Septoria Speckled Leaf Blotch, caused by the fungus Zymoseptoria passerinii, last appeared in North America in the early 2000s. Although rare in crops, field sampling of wild grasses in the Middle East revealed the disease persistence in wild barley. Identification of Z.

A Yeast-Based Assay for Inhibitors of l-Lactate Transport Utilizing Fluorescent Biosensors.

Inhibitors of ʟ-lactate transport are in development as a novel mode of action in antitumor therapy and malaria. Previously, we used radiolabeled ʟ-lactate to assay transport via the human monocarboxylate transporter 1, MCT1, and the structurally unrelated malaria parasite's transporter, PfFNT. We encountered a sensitivity limit at IC around 100 nM possibly resulting from the required high cell number per sample.

Gut microbiota diversity repeatedly diminishes over time following maintenance infliximab infusions in paediatric IBD patients.

Background: The gut microbiome plays a crucial role in the pathogenesis and progression of inflammatory bowel disease (IBD). Understanding the dynamics of the gut microbiome in relation to treatment can provide valuable insights into disease management and therapy strategies. The aim of this study is to investigate if diversity and composition of the gut microbiome correlate with time since treatment and disease activity during maintenance infliximab (IFX) therapy among children with IBD.

The role of allergen-specific regulatory T cells in the control of allergic disease.

Allergies result from an antigen-specific loss of tolerance against innocuous foreign substances. Allergen immunotherapy (AIT) aims to reverse the pathogenic response and to re-establish physiological tolerance. However, the tolerogenic mechanisms that prevent allergy in healthy and act during AIT are still obscure.

Tumor budding and lymphovascular invasion as prognostic factors in p16-positive oropharyngeal squamous cell carcinomas.

Background: We aimed to validate the prognostic significance of tumor budding (TB) in p16-positive oropharyngeal squamous cell carcinomas (OPSCC).

Methods: We analyzed digitized H&E-stained slides from a multicenter cohort of five large university centers consisting of n = 275 cases of p16-positive OPSCC. We evaluated TB along with other histological parameters (morphology, tumor-stroma-ratio, lymphovascular invasion (LVI), perineural invasion) and calculated survival outcomes using both univariate and multivariate analyses.

Similarities and Differences in Diurnal Salivary Adrenal Hormones in Monozygotic Twins with Discordant Birthweight.

Introduction: Dehydroepiandrosterone sulphate is increased in formerly small-for-gestational age singletons and in smaller twins compared to their normal-weight co-twin. Less is known concerning other adrenal hormones. We compared diurnal salivary profiles in monozygotic twins with intra-twin birthweight (bw) differences to analyse the long-term impact of bw and persistent intra-twin auxological differences on various adrenal hormones.

Gut microbiota diversity is prognostic and associated with benefit from chemo-immunotherapy in metastatic triple-negative breast cancer.

The gut microbiota influences multiple aspects of human health and disease. Several studies have indicated an association between the gut microbiota and response to immune checkpoint inhibitors in various cancers, but there is scarce data from breast cancer. The randomized ALICE trial demonstrated improved progression-free survival (PFS) from adding the programmed cell death 1 ligand 1 (PD-L1) inhibitor atezolizumab (atezo) to immunomodulating chemotherapy (chemo) in metastatic triple-negative breast cancer (mTNBC), even for PD-L1 disease.
