Differences in the pathological, transcriptomic, and prognostic implications of lymphoid structures between primary and metastatic cutaneous melanomas.

Background: While the prognostic role of tertiary lymphoid structures (TLS) has been well studied in solid cancers, the prevalence and impact of immature precursor lymphoid structures known as lymphoid aggregates (LA) remain unresolved in relation to the disease process. In this study, we examined characteristics and the prognostic utility of LA and TLS status in histological samples from patients with melanoma.

Methods: We assessed The Cancer Genomic Atlas-skin cutaneous melanoma digital slides and melanoma specimens from the University of Pittsburgh for the presence of LA and TLS using H&E staining, multiplex immunofluorescence (mIF) and transcriptomic analyses.

Protective effect of mesenchymal stromal cells in diabetic nephropathy: the In vitro and In vivo role of the M-Sec-tunneling nanotubes.

Mitochondrial dysfunction plays an important role in the development of podocyte injury in diabetic nephropathy (DN). Tunnelling nanotubes (TNTs) are long channels that connect cells and allow organelle exchange. Mesenchymal stromal cells (MSCs) can transfer mitochondria to other cells through the M-Sec-TNTs system.

Early vascular aging in chronic kidney disease: focus on microvascular maintenance, senescence signature and potential therapeutics.

Chronic kidney disease (CKD) is a strong risk factor for cardiovascular mortality and morbidity. We hypothesized that a senescent phenotype instigated by uremic toxins could account for early vascular aging (EVA) and vascular dysfunctions of microvasculature in end stage kidney disease (ESKD) patients which ultimately lead to increased cardiovascular complication. To test this hypothesis, we utilized both in vivo, and ex vivo approaches to study endothelial and smooth muscle function and structure, and characterized markers related to EVA in 82 ESKD patients (eGFR <15 ml/min) and 70 non-CKD controls.

Mandatory role of endoplasmic reticulum in preserving NADPH regeneration in starved MDA-MB-231 breast cancer cells.

Cancer growth requires high amount of nicotinamide adenine dinucleotide phosphate (NADPH) to feed the anabolic reactions and preserve the redox balance. NADPH level is largely preserved by the oxidative arm of the pentose phosphate pathway (PPP). Here, we show that prolonged glucose deprivation of triple negative breast cancer MDA-MB-231 cells decreases proliferation rate, promotes hexose funneling to glycolysis hampering the PPP.

Chronotype and lifestyle in the transition to adulthood: Exploring the role of sleep health and circadian misalignment.

Objectives: The present study aimed at exploring the association between eveningness and lifestyle-related variables, that is, body mass index, alcohol, and cigarette consumption, in adults (18-40years), focusing on the possible moderator effect of age and the role of sleep disturbances and circadian misalignment (social jetlag).

Methods: A web-based survey was administered to 437 participants, covering demographics, lifestyle-related variables, chronotype, sleep quality, and daytime sleepiness. A subset of 206 participants wore a wrist actigraph for a week, allowing the creation of a sleep health index within the RU-SATED framework.

Optimizing Femoral Access in Emergency EVAR with a Decision-Making Algorithm.

Endovascular aneurysm repair (EVAR) has become the preferred approach over open repair for abdominal aortic aneurysms (AAAs) due to its minimally invasive nature. The common femoral artery (CFA) is the main access vessel for EVAR, with both surgical exposure and percutaneous access being utilized. However, in emergent cases, percutaneous access can be challenging and may result in complications such as bleeding or dissection thrombosis, leading to the need for surgical conversion.

Tracking Response and Resistance in Acute Myeloid Leukemia through Single-Cell DNA Sequencing Helps Uncover New Therapeutic Targets.

Acute myeloid leukemia (AML) is an aggressive hematologic neoplasia with a complex polyclonal architecture. Among driver lesions, those involving the gene represent the most frequent mutations identified at diagnosis. The development of tyrosine kinase inhibitors (TKIs) has improved the clinical outcomes of -mutated patients (Pt).

Mesenchymal Stromal Cell-Derived Extracellular Vesicles for Reversing Hepatic Fibrosis in 3D Liver Spheroids.

Hepatic fibrosis, arising from prolonged liver injury, entails the activation of hepatic stellate cells (HSCs) into myofibroblast-like cells expressing alpha-smooth muscle actin (α-SMA), thereby driving extracellular matrix deposition and fibrosis progression. Strategies targeting activated HSC reversal and hepatocyte regeneration show promise for fibrosis management. Previous studies suggest that extracellular vesicles (EVs) from mesenchymal stromal cells (MSCs) can suppress HSC activation, but ensuring EV purity is essential for clinical use.

Psychopathy and Impairments in Emotion Regulation: A systematic review and Meta-analysis.

Considering the sparse but rapidly growing literature concerning the relationship between psychopathy and emotion regulation, taking stock of accumulating knowledge in a systematic review and meta-analysis of the existing results is needed. We performed a systematic search (up to May 30, 2024) following PRISMA guidelines of five scientific databases (PsycINFO, PsycARTICLES, MEDLINE, PubMed, Scopus and Web of Science). Also, gray literature was searched.

Chemical Probes to Investigate Central Nervous System Disorders: Design, Synthesis and Mechanism of Action of a Potent Human Serine Racemase Inhibitor.

The intricate signaling network within the central nervous system (CNS) involving -methyl-d-aspartate receptors (NMDARs) has been recognized as a key player in severe neurodegenerative diseases. The indirect modulation of NMDAR-mediated neurotransmission through inhibition of serine racemase (SR)-the enzyme responsible for the synthesis of the NMDAR coagonist d-serine-has been suggested as a therapeutic strategy to treat these conditions. Despite the inherent challenges posed by SR conformational flexibility, a ligand-based drug design strategy has successfully produced a series of potent covalent inhibitors structurally related to amino acid analogues.

Chest Pain: Wellens Syndrome Due to Spontaneous Dissection of the Left Anterior Descending Coronary Artery - A Case Report and Literature Review.

Wellens syndrome is an abnormal electrocardiographic pattern characterized by biphasic (type A) or deeply inverted (type B) T waves in leads V2-V3. It is typically caused by temporary obstruction of the left anterior descending (LAD) coronary artery due to the rupture of an atherosclerotic plaque leading to occlusion. Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and even a rarer cause of Wellens Syndrome.

Extracellular Vesicles Derived from Human Liver Stem Cells Counteract Chronic Kidney Disease Development and Cardiac Dysfunction in Remnant Kidney Murine Model: The Possible Involvement of Proteases.

Fibrosis is a marker of chronic kidney disease (CKD) and consists of the accumulation of the extracellular matrix (ECM) components, causing the progressive deterioration of kidney function. Human liver stem cells (HLSCs) have anti-fibrotic activity, and HLSC-derived extracellular vesicles (EVs) mediate this effect. Herein, we evaluated the ability of HLSC-EVs to reverse renal and cardiac alterations in a murine model of partial nephrectomy (PNx) that mimics human CKD development.
