A multiphasic model for determination of mouse ascending thoracic aorta mass transport properties with and without aneurysm.

Thoracic aortic aneurysms (TAAs) are associated with aortic wall remodeling that affects transmural transport or the movement of fluid and solute across the wall. In previous work, we used a Fbln4 (MU) mouse model to investigate transmural transport changes as a function of aneurysm severity. We compared wild-type (WT), MU with no aneurysm (MU-NA), MU with aneurysm (MU-A), and MU with an additional genetic mutation that led to increased aneurysm penetrance (MU-XA).

Bile acid modulation by gut microbiota: a bridge to understanding cognitive health.

The gut microbiota plays an important role in regulating the body's physiological system, and more recently its impact on bile acid metabolism and cognitive function has been investigated by many studies. In addition to their conventional function in fat digestion and absorption, bile acids are now considered crucial signaling molecules that control several metabolic processes and immunological responses. For this purpose, the authors conducted comprehensive research using relevant terms in an attempt to understand more about the gut microbiota and its impact on bile acid metabolism and cognitive health.

Silico-Tuberculosis Mimicking Malignancy.

Silico-tuberculosis is the combination of silicosis and tuberculosis (TB). Symptoms of TB such as dyspnea, cough, and hemoptysis may precede the diagnosis of an endo-bronchial mass lesion on chest imaging. Among workers who were exposed to silica, TB was more common, and experiments indicated that silica inhibits alveolar macrophage activity and severe exposure induces apoptosis.

Stellate ganglion block & ventricular arrhythmias.

An electrical or ventricular storm is a life-threatening condition that must be treated as soon as possible. Here we have successfully saved a 32-year-old male patient with ventricular storm by going beyond the conventional treatment of ACLS. The ultrasound-guided stellate ganglion block terminates sympathetic over discharge thus terminates electrical storm.

Adverse events associated with chimeric antigen receptor T-cell therapy in ophthalmology: a narrative review.

Chimeric antigen receptors are synthetically produced receptors engineered to engage with target cells with high specificity. These cells are created by inserting an artificial T-cell receptor into an immunoglobulin's antigen-binding region, allowing the cells to combine and target specific antigens. The use of chimeric antigen receptor (CAR) T-cell therapy has been a remarkable achievement in the field of immunotherapy, particularly in the treatment of ophthalmic tumors like retinoblastoma and uveal melanoma.

Tumor Suppressor MicroRNAs in Clinical and Preclinical Trials for Neurological Disorders.

Cancers and neurological disorders are two major types of diseases in humans. We developed the concept called the "Aberrant Cell Cycle Disease (ACCD)" due to the accumulating evidence that shows that two different diseases share the common mechanism of aberrant cell cycle re-entry. The aberrant cell cycle re-entry is manifested as kinase/oncoprotein activation and tumor suppressor (TS) inactivation, which are associated with both tumor growth in cancers and neuronal death in neurological disorders.

Prognostic value of baseline and interim [F]FDG PET metabolic parameters in pediatric Hodgkin's lymphoma.

Background: Hodgkin lymphoma (HL) in pediatric populations has a high survival rate but poses risks for long-term morbidities. Although [F]fluoro‑2‑deoxy‑2‑d‑glucose positron emission tomography ([F]FDG PET) scans offer potential for improved risk stratification, the definitive prognostic value of quantitative [F]FDG PET parameters remains unclear for pediatric HL.

Methods: A single-center, retrospective study included pediatric patients diagnosed with HL between 2016 and 2023 treated according to EuroNet-PHL-C1 and DAL/GPOH-HD protocols.

Changes in vascular function and correlation with cardiotoxicity in women with newly diagnosed breast cancer undergoing HER2-directed therapy with and without anthracycline/cyclophosphamide.

Aims: The objective of this study was to assess the effect of HER2-directed therapy (HER2-Tx) on peripheral vasoreactivity and its correlation with cardiac function changes and the additive effects of anthracycline/cyclophosphamide (AC) therapy and baseline cardiovascular risk.

Methods And Results: Single-centre, prospective cohort study of women with newly diagnosed stage 1-3 HER2-positive breast cancer undergoing HER2-Tx +/- AC. All participants underwent baseline and 3-monthly evaluations with Endo-Peripheral Arterial Tonometry (Endo-PAT), vascular biomarkers [C-type natriuretic peptide (CNP) and neuregulin-1 beta (NRG-1β)], and echocardiography.

Study of chemical effects on L X-rays spectra of Pr compounds using high resolution WDXRF and EDXRF measurements.

Chemical effects on L X-rays spectra of PrF, PrCl, PrBr, PrO, PrO and Pr(SO) compounds have been investigated from measured IL/IL (i = l and β), IL/IL (j = η, γ and γ), IL/IL (k = γ and η) intensity ratios using high resolution poly-chromatic WDXRF, and monochromatic excitation by 6.49 keV in vacuum (10 Torr) and Ag K (22.581 keV) X-rays photons in EDXRF spectrometers.

Measurement of relative motion of the brain and skull in the mini-pig in-vivo.

The mechanical role of the skull-brain interface is critical to the pathology of concussion and traumatic brain injury (TBI) and may evolve with age. Here we characterize the skull-brain interface in juvenile, female Yucatan mini-pigs from 3 to 6 months old using techniques from magnetic resonance elastography (MRE). The displacements of the skull and brain were measured by a motion-sensitive MR imaging sequence during low-amplitude harmonic motion of the head.

Fabrication of thin Molybdenum backed target using rolling method.

A successful attempt was made to fabricate a thin foil of natural Mo target on a thick Au backing with Indium in between to improve adhesion between the foils. Rolling at elevated temperature was considered to fabricate Mo foil while gold foil was fabricated employing conventional rolling technique. The heating of Mo foil under natural environment lead to the oxidation or carbonization on foil surface which was confirmed through Energy Dispersive X-ray Spectroscopy (EDS) measurements.

Changes in transmural mass transport correlate with ascending thoracic aortic aneurysm diameter in a fibulin-4 E57K knockin mouse model.

Thoracic aortic aneurysm is characterized by dilation of the aortic diameter by greater than 50%, which can lead to dissection or rupture. Common histopathology includes extracellular matrix remodeling that may affect transmural mass transport, defined as the movement of fluids and solutes across the wall. We measured in vitro ascending thoracic aorta mass transport in a mouse model with partial aneurysm phenotype penetration due to a mutation in the extracellular matrix protein fibulin-4 [, referred to as MU-A (aneurysm) or MU-NA (no aneurysm)].
