Unravelling a new enzymatic activity of non-specific lipid transfer protein Cor a 8: A novel lipase from hazelnuts.

The high-fat content of hazelnuts, mainly triglycerides, makes them prone to lipid oxidation during storage, which has a big impact on their sensory and nutritional quality. The chemical pathways leading to hazelnut oxidative rancidity have been well characterized and are faster on free fatty acids. Lipase(s) enzymes are required in oilseeds to hydrolyse the ester bonds to free the single molecule of fatty acids.

Incidence, prevention and management of severe infections in patients undergoing therapy for chronic lymphocytic leukemia.

Introduction: Chronic Lymphocytic Leukemia (CLL) is a disease marked by high infectious risk due to a combination of patient, disease and treatment-related factors. As a new landscape in the therapeutic panorama is emerging with the introduction of novel agents, it is essential to understand their impact on the incidence of infectious events and consequently what prevention and management strategies should be introduced.

Areas Covered: We searched the PUBMED database considering peer-reviewed papers published between January 2013 and January 2025 that reported on at least 100 patients and provided detailed information on infectious complications.

A New Pulmonary Nodule in a Patient With a History of Lymphoma.

A 70-year-old woman who formerly used tobacco was referred for evaluation of a lung nodule incidentally discovered during hematologic follow-up. Her medical history was notable for a stage IV follicular lymphoma (G2/G3A stage IV, for pleural and perinephric involvement, FLIPI4) in September 2022, for which she received 6 courses of obinutuzumab plus bendamustine. After the second cycle of therapy, an increase in transaminases was detected; the subsequent diagnostic workup showed a positive real-time polymerase chain reaction blood test for human herpesvirus 6 DNA with more than 13,000 copies/mL.

Background: Mounting evidence underline the relevance of macromolecular complexes in cancer. Integrins frequently recruit ion channels and transporters within complexes which behave as signaling hubs. A complex composed by β1 integrin, hERG1 K channel, the neonatal form of the Na channel Na 1.

Predictors of Splenectomy Response in Immune Thrombocytopenia: A Multicentric Italian Study.

: Splenectomy leads to a high rate of remission in chronic primary immune thrombocytopenia (ITP), but its unpredictable long-term positive outcomes and that it is a irreversible surgical approach discourage clinicians and patients. The identification of predictors of response may redefine the timing of splenectomy. In this retrospective, multicentric study we aimed to investigate clinical-histological predictors of splenectomy response in ITP patients and provide an easy-to-use score to predict splenectomy response in ITP.

Decoupling Individual Host Response and Immune Cell Engager Cytotoxic Potency.

Immune cell engagers are molecular agents, usually antibody-based constructs, engineered to recruit immune cells against cancer cells and kill them. They are versatile and powerful tools for cancer immunotherapy. Despite the multiplication of engagers tested and accepted in the clinic, how molecular and cellular parameters influence their actions is poorly understood.

CD23 expression in lymphoplasmacytic lymphoma: Clinical-pathological and biological correlations.

Aims: The diagnosis of lymphoplasmacytic lymphoma (LPL) in the bone marrow (BM) is challenged by aberrant phenotypes and by overlapping histological features with marginal zone lymphoma (MZL). To address these issues, we (i) assessed LPL immunophenotype on a large series of BM samples, (ii) drew possible correlations between LPL phenotype and clinical/molecular data and (iii) investigated the role of new phenotypical markers in the differential diagnosis between LPL and MZL.

Materials And Methods: The study retrospectively considered 81 clinically annotated LPL diagnosed at Padua University Hospital (Padua, Italy) during a 5-year period.

Elucidating the unexpected cell adhesive properties of agarose substrates. The effect of mechanics, fetal bovine serum and specific peptide sequences.

2D agarose substrates have recently been surprisingly shown to be permissive for cell adhesion, depending on their mechanics and the use of the adhesive proteins of fetal bovine serum (FBS) in the cell culture medium. Here, we elucidate how the cells exhibit two anchoring mechanisms depending on the amount of FBS. Under low FBS conditions, the cells recognize the surface-coupled adhesive sequences of fibronectin via the binding of the heterodimer αβ integrin.

Baseline prognostic predictors in classical Hodgkin Lymphoma: a retrospective, single-center analysis on patients treated with PET/CT-guided ABVD.

Introduction: The identification of baseline prognostic factors in Classical Hodgkin Lymphoma could help in tailoring a risk-based approach as the therapeutic landscape expands. Currently, the International Prognostic Score (IPS) represents the most used prediction tool in clinical practice, but other potential baseline risk predictors have been identified.

Methods: We performed a retrospective analysis in a cohort of 274 patients treated with FDG-PET/CT-guided ABVD to assess the prognostic significance of the IPS risk factors, and to validate the impact of the peripheral blood lymphocyte to monocyte (LMR) and neutrophil to lymphocyte (NLR) ratios on prognosis definition.

Protein kinase CK2α is overexpressed in classical hodgkin lymphoma, regulates key signaling pathways, PD-L1 and may represent a new target for therapy.

Introduction: In classical Hodgkin lymphoma (cHL), the survival of neoplastic cells is mediated by the activation of NF-κB, JAK/STAT and PI3K/Akt signaling pathways. CK2 is a highly conserved serine/threonine kinase, consisting of two catalytic (α) and two regulatory (β) subunits, which is involved in several cellular processes and both subunits were found overexpressed in solid tumors and hematologic malignancies.

Methods And Results: Biochemical analyses and assays showed an impaired expression of CK2 subunits in cHL, with CK2α being overexpressed and a decreased expression of CK2β compared to normal B lymphocytes.

Decoherence and Momentum Relaxation in Fermi-Polaron Rabi Dynamics: A Kinetic Equation Approach.

Despite the paradigmatic nature of the Fermi-polaron model, the theoretical description of its nonlinear dynamics poses challenges. Here, we apply a quantum kinetic theory of driven polarons to recent experiments with ultracold atoms, where Rabi oscillations between a Fermi-polaron state and a noninteracting level were reported. The resulting equations separate decoherence from momentum relaxation, with the corresponding rates showing a different dependence on microscopic scattering processes and quasiparticle properties.

Exploring the prognostic role of complex karyotype in chronic lymphocytic leukaemia patients treated with venetoclax-based regimens.

Although the unfavourable prognostic role of complex karyotype (CK) in chronic lymphocytic leukaemia (CLL) patients treated with chemoimmunotherapy has been clarified, its impact on the outcome of patients being treated with novel targeted agents, and especially with venetoclax-based regimens, remains to be resolved. In fact, only few studies, utilizing data derived from clinical trials (e.g.

Impact of the presence and number of chromosomal abnormalities on the clinical outcome in Waldenström Macroglobulinemia: a monocentric experience.

The prognostic and predictive role of specific gene mutations in Waldenström Macroglobulinemia (WM) is well-ascertained whereas the clinical impact of chromosome aberrations is far less known. Recent work has provided initial evidence for an adverse prognostic impact of some aberrations, such as del(6q), while other studies suggest a possible relationship between some clinical features (e.g.

When Waldenström macroglobulinemia hits the kidney: Description of a case series and management of a "rare in rare" scenario.

Background: Renal injury related to Waldenström macroglobulinemia (WM) occurs in approximately 3% of patients. Kidney biopsy is crucial to discriminate between distinct histopathological entities such as glomerular (amyloidotic and non-amyloidotic), tubulo-interstitial and non-paraprotein mediated renal damage. In this context, disease characterization, management, relationship between renal, and hematological response have been poorly explored.

Chronic Lymphocytic Leukemia (CLL) with Borderline Immunoglobulin Heavy Chain Mutational Status, a Rare Subgroup of CLL with Variable Disease Course.

Chronic lymphocytic leukemia (CLL) exhibits substantial variability in disease course. The mutational status of the B-cell receptor immunoglobulin heavy variable (IGHV) chain is a critical prognostic factor, categorizing patients into mutated (M-IGHV) and unmutated (U-IGHV) groups. Recently, a third subgroup with borderline mutational status (BL-IGHV) has been identified, comprising approximately 5% of CLL cases.

Ionic Strength Impacts the Physical Properties of Agarose Hydrogels.

Agarose is a natural polysaccharide known for its ability to form thermoreversible hydrogels. While the effects of curing temperature and polysaccharide concentration on mechanical properties have been discussed in the literature, the role of ionic strength has been less studied. In the present manuscript, we investigate the effects of supporting salt concentration and the role of cation (i.

CK2β Regulates Hematopoietic Stem Cell Biology and Erythropoiesis.

The Ser-Thr kinase CK2 plays important roles in sustaining cell survival and resistance to stress and these functions are exploited by different types of blood tumors. Yet, the physiological involvement of CK2 in normal blood cell development is poorly known. Here, we discovered that the β regulatory subunit of CK2 is critical for normal hematopoiesis in the mouse.

Refractory celiac disease and its mimickers: a review on pathogenesis, clinical-pathological features and therapeutic challenges.

Refractory celiac disease (RCD) and enteropathy-associated T-cell lymphoma (EATL) are rare, yet severe complications of celiac disease (CD). Over the last decades, several studies have addressed the biology and clinical-pathological features of such conditions, highlighting unique disease patterns and recurrent genetic events. Current classification proposals identify two forms of RCD, namely: (i) type 1 RCD (RCD-I), characterized by phenotypically normal intra-epithelial lymphocytes (IELs); and (ii) type 2 RCD (RCD-II), featuring phenotypically aberrant IELs.

Integrins regulate hERG1 dynamics by girdin-dependent Gαi3: signaling and modeling in cancer cells.

The hERG1 potassium channel is aberrantly over expressed in tumors and regulates the cancer cell response to integrin-dependent adhesion. We unravel a novel signaling pathway by which integrin engagement by the ECM protein fibronectin promotes hERG1 translocation to the plasma membrane and its association with β1 integrins, by activating girdin-dependent Gαi3 proteins and protein kinase B (Akt). By sequestering hERG1, β1 integrins make it avoid Rab5-mediated endocytosis, where unbound channels are degraded.
