Purpose: Emerging nuclear imaging technologies are advancing the field of spinal diagnostics for degenerative changes. This study aimed to describe the prevalence of spinal hot spots in an orthopedic population undergoing bone scintigraphy (BS) for reasons unrelated to the spine and to assess the correlation of these hot spots with the presence of corresponding spinal complaints.

Methods: A retrospective analysis of patients from the Department of Orthopedic Surgery and Traumatology who provided general consent for the use of their medical data.

A process monitoring microreactor assembly for real-time reaction analysis using inline near-infrared spectroscopy and chemometrics.

The occurrence of highly exothermic and potential runaway reactions represents a significant hazard to workers, facilities, and the surrounding ecosystem. Due to their high reaction velocity, these reactions often prove difficult to monitor. In many instances, the recorded data result from several single-quantity sensors, such as temperature and pressure sensors.

Lactic acid in the vaginal milieu modulates the -host interaction.

Vulvovaginal candidiasis (VVC) is one of the most common infections caused by . VVC is characterized by an inadequate hyperinflammatory response and clinical symptoms associated with colonization of the vaginal mucosa. Compared to other host niches in which can cause infection, the vaginal environment is extremely rich in lactic acid that is produced by the vaginal microbiota.

Shape-matching-based fracture reduction aid concept exemplified on the proximal humerus-a pilot study.

Purpose: Optimizing fracture reduction quality is key to achieve successful osteosynthesis, especially for epimetaphyseal regions such as the proximal humerus (PH), but can be challenging, partly due to the lack of a clear endpoint. We aimed to develop the prototype for a novel intraoperative C-arm-based aid to facilitate true anatomical reduction of fractures of the PH.

Methods: The proposed method designates the reduced endpoint position of fragments by superimposing the outer boundary of the premorbid bone shape on intraoperative C-arm images, taking the mirrored intact contralateral PH from the preoperative CT scan as a surrogate.

Monitoring of the Biotechnological Production of Dihydroxyacetone Using a Low-Field H NMR Spectrometer.

The concept of sustainable production necessitates the utilization of waste and by-products as raw materials, the implementation of biotechnological processes, and the introduction of automated real-time monitoring for efficient use of resources. One example is the biocatalyzed conversion of the reusable by-product glycerin by acetic acid bacteria to dihydroxyacetone (DHA), which is of great importance to the cosmetic industry. The application of compact spectrometers enables the rapid measurement of samples while simultaneously reducing the consumption of resources and energy.

Exploring the innate immune response in polycystic liver disease.

Rationale: The role of the innate immune system in polycystic liver disease (PLD) has been underexplored despite its potential importance in disease progression. This study explores the innate immune response in PLD patients by analyzing cytokine production of peripheral blood mononuclear cells (PBMCs) in response to various pathogens compared to healthy controls.

Methods: Samples were collected from patients with ADPLD or ADPKD and PLD.

Clavicle Shaft Non-Unions-Do We Even Need Bone Grafts?

The surgical treatment of bony non-unions is traditionally performed with additional bone grafts when atrophic and/or stronger implants when hypertrophic. In the case of the clavicle shaft, however, in our experience, a more controversial method where no additional bone graft is needed leads to equally good consolidation rates, independent of the non-union morphology. This method requires the meticulous anatomical reconstruction of the initial fracture and fixation according to the AO principle of relative stability.

Digoxin treatment does not reinduce radioiodine uptake in radioiodine refractory non-medullary thyroid carcinoma.

Objective: Patients with non-medullary thyroid carcinoma (NMTC) that are refractory to radioactive iodine (RAI) have a poor prognosis. Strategies for restoring the ability to take up iodine, so-called redifferentiation, are promising but not suitable for all patients. Preclinical studies, in human cell lines just as in a murine model, have shown that the cardiac glycoside digoxin restored RAI uptake.

Pesticide Identification Using Surface-Enhanced Raman Spectroscopy and Density Functional Theory Calculations: From Structural Insights to On-Site Detection.

Mechanistic study of the electrochemical oxidation of fluoroquinolones: Ciprofloxacin, danofloxacin, enoxacin, levofloxacin and lomefloxacin.

The fluoroquinolones ciprofloxacin, danofloxacin, enoxacin, levofloxacin and lomefloxacin, occur in water bodies worldwide and therefore pose a threat to the aquatic environment. Advanced purification procedures, such as electrochemical oxidation, may act as a remedy since they contribute to eliminating contaminants and prevent micropollutants from entering open water bodies. By electrochemical treatment in a micro-flow reactor equipped with a boron-doped diamond (BDD) electrode, the fluoroquinolones were efficiently degraded.

Alpha1-antitrypsin impacts innate host-pathogen interactions with by stimulating fungal filamentation.

Our immune system possesses sophisticated mechanisms to cope with invading microorganisms, while pathogens evolve strategies to deal with threats imposed by host immunity. Human plasma protein α1-antitrypsin (AAT) exhibits pleiotropic immune-modulating properties by both preventing immunopathology and improving antimicrobial host defence. Genetic associations suggested a role for AAT in candidemia, the most frequent fungal blood stream infection in intensive care units, yet little is known about how AAT influences interactions between and the immune system.

The interaction between the Candida albicans cell wall and pattern recognition receptors is crucial for the initiation of host immune responses, which, ultimately, contribute to the clearance of this pathogenic fungus. In the present study, we investigate the ability of C. albicans mannans to modulate immune response and induce innate immune memory (also termed trained immunity).

Choice of DNA extraction method affects stool microbiome recovery and subsequent phenotypic association analyses.

The lack of standardization in the methods of DNA extraction from fecal samples represents the major source of experimental variation in the microbiome research field. In this study, we aimed to compare the metagenomic profiles and microbiome-phenotype associations obtained by applying two commercially available DNA extraction kits: the AllPrep DNA/RNA Mini Kit (APK) and the QIAamp Fast DNA Stool Mini Kit (FSK). Using metagenomic sequencing data available from 745 paired fecal samples from two independent population cohorts, Lifelines-DEEP (LLD, n = 292) and the 500 Functional Genomics project (500FG, n = 453), we confirmed significant differences in DNA yield and the recovered microbial communities between protocols, with the APK method resulting in a higher DNA concentration and microbial diversity.
