P2 Receptor Antagonists Rescue Defective Heme Content in an In Vitro SLC25A38-Associated Congenital Sideroblastic Anemia Cell Model.

Mutations in the SLC25A38 gene are responsible for the second most common form of congenital sideroblastic anemia (CSA), a severe condition for which no effective treatment exists. We developed and characterized a K562 erythroleukemia cell line with markedly reduced expression of the SLC25A38 protein (A38-low cells). This model successfully recapitulated the main features of CSA, including reduced heme content and mitochondrial respiration, increase in mitochondrial iron, ROS levels and sensitivity to oxidative stress.

First-line immune-based combinations or sunitinib in favorable-risk metastatic renal cell carcinoma: a real-world retrospective comparison from the ARON-1 study.

Introduction: Renal cell carcinoma (RCC) is one of the most common types of urogenital cancer. The introduction of immune-based combinations, including dual immune-checkpoint inhibitors (ICI) or ICI plus tyrosine kinase inhibitors (TKIs), has radically changed the treatment landscape for metastatic RCC, showing varying efficacy across different prognostic groups based on the International Metastatic RCC Database Consortium (IMDC) criteria.

Materials And Methods: This retrospective multicenter study, part of the ARON-1 project, aimed to evaluate the outcomes of favorable-risk metastatic RCC patients treated with immune-based combinations or sunitinib.

Discriminative stimulus properties of α-ethyltryptamine (α-ET) in rats: α-ET-like effects of MDMA, MDA and aryl-monomethoxy substituted derivatives of α-ET.

Rationale α-ET (α-ethyltryptamine), a homolog of the classical hallucinogen α-methyltryptamine, was once prescribed clinically as an antidepressant. Classical psychedelic drugs are currently of interest as potential pharmacotherapy for psychiatric disorders. Objectives Drug discrimination was used to (a) determine if α-ET-like stimulus effects could be engendered by the prototypical phenylalkylamines MDMA ("Ecstasy") or MDA ("Love Drug") and (b) evaluate the α-ET-like stimulus effects of four synthesized aryl-substituted monomethoxy analogs of α-ET (4-OMe-, 5-OMe-, 6-OMe- and 7-OMe-α-ET).

Variations of blood D-serine and D-aspartate homeostasis track psychosis stages.

Schizophrenia (SCZ) is a severe psychotic disorder characterized by a disruption in glutamatergic NMDA receptor (NMDAR)-mediated neurotransmission. Compelling evidence has revealed that NMDAR activation is not limited to L-glutamate, L-aspartate, and glycine since other free amino acids (AAs) in the atypical D-configuration, such as D-aspartate and D-serine, also modulate this class of glutamatergic receptors. Although dysregulation of AAs modulating NMDARs has been previously reported in SCZ, it remains unclear whether distinct variations of these biomolecules occur during illness progression from at-risk premorbid to clinically manifest stage.

Enhancing magnesium-based materials for biomedical applications using an innovative strategy of combined single point incremental forming and bioactive coating.

Background: Magnesium (Mg) and its alloys are promising candidates for biodegradable materials in next-generation bone implants due to their favourable mechanical properties and biodegradability. However, their rapid degradation and corrosion, potentially leading to toxic byproducts, pose significant challenges for widespread use.

Objectives: This study aimed to address the challenges associated with Mg-based materials by thoroughly evaluating the biocompatibility, genotoxicity, and mechanical properties of Mg-based devices manufactured via Single Point Incremental Forming (SPIF).

This pilot multimethod study aimed to preliminarily understand the relationship between motivations for enrolment and dropout among first-year undergraduate nursing students.

Methods: A two-step approach was conducted among first-year nursing students from five Italian universities involving: (a) a baseline quantitative online survey collecting their characteristics and motivations for enrolment; (b) a follow-up semi-structured interview qualitative data collection among students who dropped out.

Breath Analysis: Identification of Potential Volatile Biomarkers for Non-Invasive Diagnosis of Chronic Kidney Disease (CKD).

Recently, volatile organic compound (VOC) determination in exhaled breath has seen growing interest due to its promising potential in early diagnosis of several pathological conditions, including chronic kidney disease (CKD). Therefore, this study aimed to identify the breath VOC pattern providing an accurate, reproducible and fast CKD diagnosis at early stages of disease. A cross-sectional observational study was carried out, enrolling a total of 30 subjects matched for age and gender.

Rapid and random-start endometrial preparation before outpatient hysteroscopic polypectomy in patients of perimenopausal age.

Objective: This study aimed to assess the efficacy of randomly started oral dienogest/ethinylestradiol (DNG/EE) for swift endometrial preparation prior to outpatient hysteroscopic polypectomy in perimenopausal women.

Method: A multicenter, prospective, randomized controlled trial was conducted in university hospitals. Eighty perimenopausal women scheduled for outpatient hysteroscopic polypectomy between January 2023 and March 2024 were randomly assigned to either intervention ( = 40) or control ( = 40) groups.

Preclinical study of the antimyotonic efficacy of safinamide in the myotonic mouse model.

Mexiletine is the first choice drug in the treatment of non-dystrophic myotonias. However, 30% of patients experience little benefit from mexiletine due to poor tolerability, contraindications and limited efficacy likely based on pharmacogenetic profile. Safinamide inhibits neuronal voltage-gated sodium and calcium channels and shows anticonvulsant activity, in addition to a reversible monoamine oxidase-B inhibition.

Real-life effectiveness and safety of baricitinib in patients with severe alopecia areata: A 24-week Italian study.

Background: Alopecia areata is an autoimmune condition characterized by rapid hair loss in the scalp, eyebrows and eyelashes, for which treatments are limited. Baricitinib, an oral inhibitor of Janus kinases 1 and 2, has been recently approved to treat alopecia areata.

Materials And Methods: We conducted a retrospective study involving 23 medical centres across Italy, enrolling patients affected by severe alopecia areata (SALT >50), for more than 6 months.

Assessing a measure for Quality of Life in patients with severe Alopecia Areata: a multicentric Italian study.

Objective: The prevalence of anxiety and depression in patients diagnosed with Alopecia Areata (AA) is very high and this significant burden of psychological symptoms threatens the Health-Related Quality of Life (HRQoL) of affected patients. Indeed, AA often does not produce significant physical symptoms, but it nonetheless disrupts many areas of mental health. Clinical assessment of disease severity may not reliably predict patient's HRQoL, nor may it predict the patient's perception of illness.

Effect of Mitoquinone on sperm quality of cryopreserved stallion semen.

This study aimed to investigate the effect of mitochondria-targeted antioxidants (Mitoquinone, MitoQ) on the quality of frozen-thawed stallion semen. Semen samples collected from three fertile stallions aged 10 - 13 years, were filtered, centrifuged in a skimmed milk-based extender, and diluted to a final concentration of 50 × 106 sperm/mL in freezing medium. Diluted semen was divided into five experimental groups supplemented with MitoQ at concentrations of 0 (control), 25, 50, 100, and 200 nM and then subjected to freezing after cooling and equilibration.

Design, synthesis and biological evaluation of multitarget hybrid molecules containing NHC-Au(I) complexes and carbazole moieties.

N-heterocyclic carbenes (NHCs) represent suitable ligands for rapid and efficient drug design, because they offer the advantage of being easily chemically modified and can bind several substituents, including transition metals as, for instance, gold derivatives. Gold-NHC complexes possess various biological activities and were demonstrated good candidates as anticancer drugs. Besides, carbazole derivatives are characterized by various pharmacological properties, such as anticancer, antibacterial, anti-inflammatory, and anti-psychotropic.

Architectural approach to evaluate the design and management of almond cultivars suitable for super high-density orchards.

Introduction: The almond tree is a major global nut crop, and its production has surged dramatically in recent years. Super high-density (SHD) planting systems, designed to optimize resource efficiency and enhance precocity, have gained prominence in almond cultivation. A shift in cropping systems toward sustainable intensification (SI) pathways is imperative, and so maximizing branching density within the canopies of SHD trees is crucial to establish and maintain productive potential, especially for hedge-pruned trees.

Background: Neuroendocrine Carcinomas (NECs) prognosis is poor.No standard second-line therapy is currently recognized after failure of platinum-based first-line treatment. FOLFIRI and CAPTEM regimens have shown promising activity in preliminary studies.

The real-world observational prospective study of health outcomes with dulaglutide and liraglutide in type 2 diabetes patients (TROPHIES): resource use and costs of treatment in clinical practice in France, Germany, and Italy.

Aims: To describe healthcare resource utilization (HCRU) and associated costs after initiation of injectable glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy by adult patients with type 2 diabetes (T2D) in the prospective, observational, 24-month TROPHIES study in France, Germany, and Italy.

Materials And Methods: HCRU data for cost calculations were collected by treating physicians during patient interviews at baseline and follow-up visits approximately 6, 12, 18, and 24 months after GLP-1 RA initiation with once-weekly dulaglutide or once-daily liraglutide. Costs were evaluated from the national healthcare system (third-party payer) perspective and updated to 2018 prices.

Mass spectrometric characterization of aminophospholipids containing N-(2-hydroxyethyl)glycine in kombu algae extracts.

Rationale: 1,2-Diacyl-sn-glycero-3-phospho-O-[N-(2-hydroxyethyl)glycines] (PHEGs) are a class of rare aminophospholipids found specifically in brown algae, including kombu seaweed. Despite their potential importance in algal physiology, a comprehensive mass spectrometry (MS) characterization, useful to understand their biological behaviour, is still lacking.

Methods: To establish the structural regiochemical features of PHEGs, we employed hydrophilic interaction liquid chromatography (HILIC).
