: Clinically inactive corneal scars have repeatedly been shown to exhibit histological inflammation. This study aimed to evaluate the degree of histological inflammation in clinically inactive corneal scars of different origins and its correlation with graft rejection and failure following penetrating keratoplasty. : The study included 205 primary corneal explants with clinically inactive central scars resulting from herpes simplex virus keratitis (HSV, = 55), keratoconus ( = 39), mechanical trauma ( = 27), scrophulosa ( = 22) or other/unknown causes ( = 62).

Background: Portal vein thrombosis (PVT) leads to portal hypertension (PH) with its sequelae. Computed tomography spleno-mesenterico-portography (CT-SMPG) combines sequential CT spleno-portography and CT mesenterico-portography. CT-SMPG comprehensively illustrates the venous hemodynamic changes due to PH.

Intravenously transplanted mesenchymal stromal cells (MSCs) have been shown to interact with endothelial cells and to migrate to tissues. However, intracellular signals regulating MSC migration are still incompletely understood. Here, we analyzed the role of Rap1 GTPase in the migration of human bone marrow-derived MSCs in vitro and in short-term homing in mice in vivo.

Recent genome-wide association studies (GWASs) of several individual sleep traits have identified hundreds of genetic loci, suggesting diverse mechanisms. Moreover, sleep traits are moderately correlated, so together may provide a more complete picture of sleep health, while illuminating distinct domains. Here we construct novel sleep health scores (SHSs) incorporating five core self-report measures: sleep duration, insomnia symptoms, chronotype, snoring, and daytime sleepiness, using additive (SHS-ADD) and five principal components-based (SHS-PCs) approaches.

Background: Physical activity supports weight regulation and metabolic health, but its timing in relation to obesity and diabetes remains unclear. We aimed to assess the diurnal timing of physical activity and its association with obesity and diabetes.
Methods: We cross-sectionally analyzed hip-worn accelerometry data from 61,116 participants aged 20-75 in the German National Cohort between 2015 and 2019.

Bacterial cell division and plant chloroplast division require selfassembling Filamentous temperature-sensitive Z (FtsZ) proteins. FtsZ proteins are GTPases sharing structural and biochemical similarities with eukaryotic tubulin. In the moss Physcomitrella, the morphology of the FtsZ polymer networks varies between the different FtsZ isoforms.

The accurate diagnosis of central serous chorioretinopathy (CSC) and its distinction from differential diagnoses is crucial for effective patient counseling and treatment. This is achieved through a targeted patient history and multimodal imaging, which distinguish CSC from other ocular diseases also characterized by subretinal fluid and changes in the retinal pigment epithelium. In this article we identify the key differential diagnoses of CSC and illustrate the characteristic differential diagnostic features of each disease.

SUMMARYThe development of multicellularity represents a key evolutionary transition that is crucial for the emergence of complex life forms. Although multicellularity has traditionally been studied in eukaryotes, it originates in prokaryotes. Coordinated aggregation of individual cells within the confines of a colony results in emerging, higher-level functions that benefit the population as a whole.

Non-A non-B aortic dissection remains a complex and controversial topic in cardiovascular management, eliciting varied approaches among cardiologists and surgeons. Due to the limited evidence surrounding this condition, existing guidelines are limited in the complexity of their recommendations. While most patients are initially managed medically, invasive treatment becomes necessary in a large proportion of patients.

Background/objectives: Based on previous data reporting the status of health professionals' training about sleep clinical psychophysiology, insomnia, and its treatment in the US and Canada, this paper aims at providing a snapshot of the Italian situation, considering health professionals qualified to offer cognitive behavioral therapy (CBT). Adding information on different countries is important, as national health systems differ significantly, and distinct evidence-based pathways for change may be proposed.
Methods: Two hundred and thirteen CBT professionals (180 females; 33 males) answered a 5 min survey about their training and experience in recognizing and treating behavioral sleep disorders in their practice.

Background: Conflicting data exist regarding sex-specific outcomes after cardiac arrest. This study investigates sex disparities in the provision of critical care and outcomes of in-hospital (IHCA) and out-of-hospital cardiac arrest (OHCA) patients.
Methods: Analysis of adult cardiac arrest patients admitted to certified Swiss intensive care units (ICUs) (01/2008-12/2022) using the nationwide prospective ICU registry.

Objective: Helicobacter pylori is known for colonizing the gastric mucosa and instigating severe upper gastrointestinal diseases such as gastritis, gastroduodenal ulcers, and gastric cancer. To date, there is no data available on the oral cavity as transmission site, whether H. pylori can survive in the oral cavity or in human saliva.

This experimental phantom study investigates current standard of care protocols in cone beam computed tomography (CBCT), energy-integrating-detector (EID) CT, and photon-counting-detector (PCD) CT regarding their potential in delineation of dental root canals. Artificial accessory canals (diameters: 1000, 600, 400, 300 and 200 μm) were drilled into three bovine teeth mounted on a bovine rib as a jaw substitute. The phantom was scanned in two dental CBCTs, two EID-CTs and a PCD-CT using standard clinical protocols.

Background: The internet is a key source of health information, but the quality of content from popular search engines varies, posing challenges for users-especially those with low health or digital health literacy. To address this, the "tala-med" search engine was developed in 2020 to provide access to high-quality, evidence-based content. It prioritizes German health websites based on trustworthiness, recency, user-friendliness, and comprehensibility, offering category-based filters while ensuring privacy by avoiding data collection and advertisements.

Background: Peripheral nerve sheath tumors (PNSTs) encompass entities with different cellular differentiation and degrees of malignancy. Spatial heterogeneity complicates diagnosis and grading of PNSTs in some cases. In malignant PNST (MPNST) for example, single cell sequencing data has shown dissimilar differentiation states of tumor cells.

Background/objectives: Photoimmunotherapy (PIT) is an innovative approach for the targeted therapy of cancer. In PIT, photosensitizer dyes are conjugated to tumor-specific antibodies for targeted delivery into cancer cells. Upon irradiation with visible light, the photosensitizer dye is activated and induces cancer-specific cell death.

Polyphosphate kinases (PPK) play crucial roles in various biological processes, including energy storage and stress responses, through their interaction with inorganic polyphosphate (polyP) and the intracellular nucleotide pool. Members of the PPK family 2 (PPK2s) catalyse polyP‑consuming phosphorylation of nucleotides. In this study, we characterised two PPK2 enzymes from Bacillus cereus (BcPPK2) and Lysinibacillus fusiformis (LfPPK2) to investigate their substrate specificity and potential for selective nucleotide synthesis.

Traumatic brain injury is one of the most common cerebral incidences worldwide. Repetitive mild traumatic brain injuries occurring, for example, in athletes or victims of abuse, can cause chronic neurodegeneration due to neuroinflammation, in which the crosstalk between reactive astrocytes and activated microglia is crucial for modulating neuronal damage. The inducible enzyme heme oxygenase-1 and its product carbon monoxide are known to be ascribed neuroprotective and anti-inflammatory properties.
