The ADP-ribosyl hydrolases PARG and ARH3 counteract PARP enzymatic activity by removing ADP-ribosylation. PARG and ARH3 activities have a synthetic lethal effect; however, the specific molecular mechanisms underlying this response remain unknown. Here, we show that the PARG and ARH3 synthetic lethality is enhanced further in the presence of DNA alkylating agents, suggesting that the inability to revert ADP-ribosylation primarily affects the repair of alkylated DNA bases.

The use of bioelectrical impedance analysis (BIA) is now well established in healthcare as an essential support tool for patient management in various clinical settings. Its use in sports is rapidly expanding due to the valuable insights it offers, helping to better structure athletes' diets and training programs, thereby optimizing their performance. In the context of sport, however, there is a consensus regarding the importance of proper interpretation of BIA-derived data, which cannot be limited to mere estimation of body composition.

The advent of immune checkpoint inhibitors (ICIs) has deeply reshaped the therapeutic algorithm of triple-negative breast cancer (TNBC). However, there is considerable scope for better engagement of the immune system in other BC subtypes. ICIs have paved the way for investigations into emerging immunotherapeutic strategies, such as immune cell engagers (ICEs) that work by promoting efficient tumor cell killing through the redirection of immune system against cancer cells.

In several physiopathological processes, phosphatidylserine (PS), normally sequestered to the inner leaflet of the plasma membrane, becomes exposed to the cell surface. In erythrocytes (RBC), PS externalization is a crucial event for the removal of aged/damaged cells but can also be associated with increased prothrombotic activity. Structurally related olive oil antioxidants, including hydroxytyrosol (HT), are able to significantly reduce the percentage of PS-exposing RBC, when cells are exposed to toxic compounds such as the heavy metal mercury (Hg).

Contrast associated acute kidney injury (CA-AKI) is a major complication of contrast media (CM) exposure following percutaneous coronary intervention (PCI), associated with high rates of morbidity and mortality in both early and late phases. During the past years, several CA-AKI prevention strategies based on CM sparing have been proposed, which differ significantly in terms of methodological features and efficacy. In this review, we propose a new classification of these techniques based on their dependency on operators' management.

Aims: Fibroblast growth factor 21 (FGF21) decreases hepatic lipogenesis in animal models, and FGF21 analogues decrease serum triglycerides (TG) in adults in phase-2 trials. On the other hand, serum FGF21 is associated with higher TG in observational studies of people with obesity, raising a sort of paradox. We tested the hypothesis that FGF21 is induced by TG in youth with obesity, as a compensatory mechanism.

Introduction: During mitosis, chromosome alignment at the mitotic spindle equator grants correct chromosome segregation and proper nuclei formation in daughter cells. The kinesin 8 family member Kif18A plays a crucial role for chromosome alignment by localizing at the kinetochore-microtubule (K-MT) plus ends to dampen MT dynamics and stabilize K-MT attachments. Kif18A action is directly antagonized by the master mitotic kinase cyclin B-dependent kinase 1 (Cdk1) and is promoted by protein phosphatase 1 (PP1).

Background: Pure autonomic failure (PAF) presents with progressive autonomic failure without other neurological features. Atypical presentations may lead to diagnostic uncertainty. We studied whether cutaneous phosphorylated-alpha-synuclein (p-syn) could distinguish between PAF, multiple system atrophy (MSA) and non-synucleinopathy-related autonomic failure, and examined its relationship with quantitative markers of cardiovascular autonomic failure.

Background: Predictors of response to neoadjuvant chemotherapy (NACT) and endocrine therapy (NET) in hormone receptor-positive (HoR+)/human epidermal growth factor receptor 2 (HER2)-negative breast cancer (BC) are required. Also, pathological and molecular changes induced by both strategies and their impact on patients' outcomes have not been reported so far.
Patients And Methods: In a cohort of 186 patients with early-stage HoR+/HER2-negative BC treated with NACT or NET, we assessed the association of baseline main clinicopathological features and PAM50 gene expression (GE), intrinsic subtypes (IS) and risk-of-relapse (ROR-P) score with pathological outcomes according to treatment strategy.

Peptidomimetics of Suppressors of cytokine signaling 1 (SOCS1) protein demonstrated valid therapeutic potentials as anti-inflammatory agents. Indeed, SOCS1 has a small kinase inhibitory region (KIR) primarily involved in the inhibition of the JAnus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) pathway Herein, on the basis of previous investigations on a potent mimetic of KIR-SOCS1, named PS5, we designed and evaluated the SAR (Structure Activity Relationship) features of two xylene-based macrocycles analogues of PS5. These novel compounds bear thiol-xylene linkages with mono- and bi-cyclic scaffolds: they were in vitro functionally investigated toward JAK2 catalytic domain, as ligands with microscale thermophoresis (MST) and as inhibitors through LC-MS analyses.

Purpose Of Review: We aim to explore the most recent insights into the pathogenesis of recurrent angioedema caused by different mechanisms and then focus on the management and treatment approaches available.
Recent Findings: The recently developed DANCE consensus classification identifies five types of angioedema: mast cell-mediated (AE-MC), bradykinin-mediated, because of intrinsic vascular endothelium dysfunction (AE-VE), drug-induced (AE-DI), and due to unknown mechanisms (AE-UNK). These subtypes require different management with treatment choices targeting the main pathogenetic pathways involved in each form.

Background: Several authors hypothesized that normative values of breast related quality of life in asymptomatic populations can be helpful to better understand changes induced by surgery. Breast related quality of life can be associated to breast anthropometry. This study was designed to explore this hypothesis, find relevant correlations and, using machine learning techniques, predict values of satisfaction with breast from easy body measurements.

In the personalized medicine era, affordable and portable devices for quicker cancer monitoring, even in remote areas, are crucial. To address this need, we have developed an enzyme-assisted electrochemical point-of-care (POC) test for application toward liquid biopsy. In particular, miR-200a-5p has been taken into account as the model target due to its correlation for triple negative breast cancer (TNBC) prognosis.

We performed a large-scale genome-wide analysis aiming to investigate the prevalence and strain-level diversity of Bifidobacteriaceae species in the human microbiome. We considered 9,528 publicly available human metagenomes and integrated them with 1,192 isolate genomes from different sources. The prevalence and abundance of Bifidobacteriaceae species in humans was linked to multiple host characteristics: they were reduced in older people and enriched in populations characterized by Westernized lifestyles with geography-specific patterns.

Previous research has highlighted the positive impact of parents on their adult children's fertility plans through childcare, but the association between parental health and fertility expectations remains unclear. Thus, this paper offers a novel perspective on the issue of family support by investigating how caregiving responsibilities toward elderly parents affect adult children's decision to have a child. Using a long panel dataset for Australia, we examine whether adult children changed their fertility expectations after becoming care providers to their parents.
