Phosphatidylserine liposomes induce a phagosome acidification-dependent and ROS-mediated intracellular killing of in human macrophages.

(Mab) is an opportunistic nontuberculous mycobacterium responsible of difficult-to-treat pulmonary infections in vulnerable patients, such as those suffering from Cystic Fibrosis (CF), where it represents a major cause of morbidity and mortality. Additionally, due to the intrinsic extensive antimicrobial resistance spectrum displayed by this species and the side effects reported for some available antibiotics, the therapeutic management of such infections remains extremely difficult. In the present study, we show that phosphatidylserine liposomes (PS-L) enhance intracellular mycobacterial killing of Mab infected human macrophages with functional or pharmacologically inhibited cystic fibrosis conductance regulator (CFTR), by a mechanism involving phagosome acidification and reactive oxygen species (ROS) production.

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.

Rearrangements in Leukemias: Molecular Aspects and Therapeutic Perspectives.

(alias: mixed-lineage leukemia []) gene mapping on chromosome 11q23 encodes the lysine-specific histone N-methyltransferase 2A and promotes transcription by inducing an open chromatin conformation. Numerous genomic breakpoints within the gene have been reported in young children and adults with hematologic disorders and are present in up to 10% of acute leukemias. These rearrangements describe distinct features and worse prognosis depending on the fusion partner, characterized by chemotherapy resistance and high rates of relapse, with a progression-free survival of 30-40% and overall survival below 25%.

New Insight for Axillary De-Escalation in Breast Cancer Surgery: "SoFT Study" Retrospective Analysis.

: The SOUND study demonstrated that an axillary de-escalation may be sufficient in locoregional and distant disease control in selected early breast cancer (EBC) patients. To establish any preoperative variables that may drive sentinel lymph node biopsy (SLNB) omission, a study named sentinel omission risk factor (SOFT) 1.23 was planned.

Self-care: An effective strategy to manage chronic diseases.

The increase in life expectancy and an aging demographic have led to a surge in chronic diseases, presenting substantial challenges to healthcare systems worldwide. Chronic conditions are characterized by their long-term nature, recurrence and incurability, necessitating effective management strategies. This paper aims to explore the concept of self-care as a pivotal element in chronic disease management, examining its evolution, components and the role of caregivers in facilitating self-care practices.

Head Nurse Leadership: Facilitators and Barriers to Adherence to Infection Prevention and Control Programs-A Qualitative Study Protocol.

Background: The effective management of Healthcare-Associated Infections (HAIs) relies on the implementation of good practice across the entire multidisciplinary team. The organizational context and the role of head nurses influence the team's performance and behavior. Understanding how decision-making processes influence healthcare professionals' behavior in the management of HAIs could help identify alternative interventions for reducing the risk of infection in healthcare organizations.

Pediatric-onset Multiple Sclerosis treatment: a multicentre observational study comparing natalizumab with fingolimod.

Background: Pediatric-onset Multiple Sclerosis (POMS) patients show more inflammatory disease compared with adult-onset MS. However, highly effective treatments are limited with only fingolimod being approved in Italy and natalizumab prescribed as off-label treatment.

Objectives: to compare the efficacy of natalizumab versus fingolimod in POMS.

Droplet dynamics in homogeneous isotropic turbulence with the immersed boundary-lattice Boltzmann method.

We develop a numerical method for simulating the dynamics of a droplet immersed in a generic time-dependent velocity gradient field. This approach is grounded on the hybrid coupling between the lattice Boltzmann (LB) method, employed for the flow simulation, and the immersed boundary (IB) method, utilized to couple the droplet with the surrounding fluid. We show how to enrich the numerical scheme with a mesh regularization technique, allowing droplets to sustain large deformations.

Integration of single-cell datasets depicts profiles of macrophages and fibro/adipogenic progenitors in dystrophic muscle.

Single-cell technologies have recently expanded the possibilities for researchers to gain, at an unprecedented resolution level, knowledge about tissue composition, cell complexity, and heterogeneity. Moreover, the integration of data coming from different technologies and sources also offers, for the first time, the possibility to draw a holistic portrait of how cells behave to sustain tissue physiology during the human lifespan and disease. Here, we interrogated and integrated publicly available single-cell RNAseq data to advance the understanding of how macrophages, fibro/adipogenic progenitors, and other cell types establish gene regulatory networks and communicate with each other in the muscle tissue.

The DNA repair protein DNA-PKcs modulates synaptic plasticity via PSD-95 phosphorylation and stability.
