PEPITEM is an immune-modulatory peptide that effectively regulates inflammation and mitigates immune-mediated inflammatory diseases (IMIDs). Here, we identify two independently active tripeptide pharmacophores within PEPITEM and engineered peptidomimetics with enhanced pharmacodynamic properties. These peptidomimetics regulate T-cell trafficking in vitro and reduce T-cell, neutrophil and macrophage numbers in the inflamed peritoneal cavity in vivo.

Whole Blood DNA Methylation Analysis Reveals Epigenetic Changes Associated with ARSACS.

Cerebellum

January 2025

Molecular Medicine for Neurodegenerative and Neuromuscular Diseases Unit, IRCCS Stella Maris Foundation, Pisa, Italy.

Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a rare inherited condition described worldwide and characterized by a wide spectrum of heterogeneity in terms of genotype and phenotype. How sacsin loss leads to neurodegeneration is still unclear, and current knowledge indicates that sacsin is involved in multiple functional mechanisms. We hence hypothesized the existence of epigenetic factors, in particular alterations in methylation patterns, that could contribute to ARSACS pathogenesis and explain the pleiotropic effects of SACS further than pathogenic mutations.

Aflatoxin B1 (AFB1) and Ochratoxin A (OTA) are considered the most important mycotoxins in terms of food safety. The aim of this study was to evaluate the hepatotoxicity of AFB1 and OTA exposure in Wistar rats and to assess the beneficial effect of fermented whey (FW) and pumpkin (P) as functional ingredients through a proteomic approach. For the experimental procedures, rats were fed AFB1 and OTA individually or in combination, with the addition of FW or a FW-P mixture during 28 days.

Genomic integrity is critical for cellular homeostasis, preventing the accumulation of mutations that can drive diseases such as cancer. Among the mechanisms safeguarding genomic stability, the Base Excision Repair (BER) pathway plays a pivotal role in counteracting oxidative DNA damage caused by reactive oxygen species. Central to this pathway are enzymes like 8-oxoguanine glycosylase 1 (OGG1), which recognize and excise 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) lesions, thereby initiating a series of repair processes that restore DNA integrity.

Diabetes is a chronic condition, and traditional monitoring methods are invasive, significantly reducing the quality of life of the patients. This study proposes the design of an innovative system based on a microcontroller that performs real-time ECG acquisition and evaluates the presence of diabetes using an Edge-AI solution. A spectrogram-based preprocessing method is combined with a 1-Dimensional Convolutional Neural Network (1D-CNN) to analyze the ECG signals directly on the device.

β-Casomorphins (BCMs), food-associated peptides resulting from the proteolytic cleavage of β-casein (β-CN), have been widely investigated for their opioid-like activity. This research aimed to identify the presence of BCM7, BCM6, and BCM5 in different bovine milk-deriving blue cheese types and to describe the intricate mechanisms behind their formation, focusing on their origin from cheese with β-CN A1 and A2 variants. Using nanoLC-ESI-Q-Orbitrap-MS/MS and advanced computational tools, we explored the peptidomes of Bleu d'Auvergne, Gorgonzola, Stilton, and Bergader blue cheeses from milk containing both β-CN A1 and A2 variants.

Background: Although little is yet known about the long-term maintenance of very low-energy ketogenic therapy (VLEKT) effects on body composition, muscle strength and inflammation, it is plausible to assume that changes may occur, particularly during the steps following the ketogenic step, due to the loss of the protective effects of ketones and the concomitant reintroduction of carbohydrates. For this reason, the present study aimed to evaluate the effects of supplementation with 8 g per day of essential amino acids (EAAs) on these parameters.

Methods: A total of 68 women of reproductive age and with grade I obesity who had completed 45 days of the ketogenic phase with VLEKT (KeNuT protocol) and 40 days of non-ketogenic phase of KeNuT protocol with VLEKT (phase 3, fruit reintroduction) were included in the study.

Under low O, the heart of Carassius auratus (goldfish) shows an enhanced hemodynamics. This is observed in ex vivo cardiac preparations from animals acclimated to both normoxia and short-term (4 days) moderate hypoxia and perfused for 90 min with a hypoxic medium. Under short-term hypoxia, this is associated with a higher ventricular muscularity and an expanded mitochondrial compartment.

Challenges in treating patients with comorbid asthma and bronchiectasis.

Respir Med

January 2025

Department of Internal Medicine ASL Salerno, 'Santa Maria della Speranza', Hospital, Salerno, Italy; Postgraduate Program in Allergy and Clinical Immunology, University of Naples 'Federico II', Naples, Italy.

The management of patients with overlapping asthma and bronchiectasis requires a tailored approach, starting with a comprehensive assessment of the patient's clinical profile, including the severity of asthma and the extent of bronchiectasis. Inhaled corticosteroids (ICS) are often recommended, but their use should be carefully monitored because of the risk of increased infection. If the asthma is well controlled and the bronchiectasis remains stable, a gradual reduction in the dose of ICS may be considered.

Gut Microbiota-Bone Axis.

Ann Nutr Metab

January 2025

Department of Translational Medical Science, University of Naples Federico II, Napoli, Italy.

Background: Knowledge of the complex interplay between gut microbiota and human health is gradually increasing as it has just recently been a field of such great interest.

Summary: Recent studies have reported that communities of microorganisms inhabiting the gut influence the immune system through cellular responses and shape many physiological and pathophysiological aspects of the body, including muscle and bone metabolism (formation and resorption). Specifically, the gut microbiota affects skeletal homeostasis through changes in host metabolism, the immune system, hormone secretion, and the gut-brain axis.

Background And Objectives: Although multiple sclerosis (MS) can be conceptualized as a network disorder, brain network analyses typically require advanced MRI sequences not commonly acquired in clinical practice. Using conventional MRI, we assessed cross-sectional and longitudinal structural disconnection and morphometric similarity networks in people with MS (pwMS), along with their relationship with clinical disability.

Methods: In this longitudinal monocentric study, 3T structural MRI of pwMS and healthy controls (HC) was retrospectively analyzed.

Introduction: Palmoplantar psoriasis (PPp) has a profound negative impact on patients' quality of life, and it represents a therapeutic challenge, as palms and soles are difficult to treat area. Although the efficacy profile of tildrakizumab has been well evaluated in the literature, data on its use for PPp are still limited. The objective of the study was to evaluate the efficacy and safety of tildrakizumab on moderate-to-severe plaque psoriasis with involvement of the palmoplantar area.

Background: The impact of sodium-glucose cotransporter-2 (SGLT2) inhibitors on mortality following myocardial infarction (MI) remains uncertain. Additionally, the role of type 2 diabetes mellitus (T2DM) and heart failure (HF) in modulating the effectiveness of these drugs post-MI are not fully understood. This meta-analysis aimed to assess the association of SGLT2 inhibitors with all-cause mortality in post-MI patients and to explore key moderators influencing this benefit.
