Abstract
Bendamustine has been retrospectively shown to be an effective and safe lymphodepletion regimen prior to the anti-CD19 chimeric antigen receptor T cell (CART) products tisagenlecleucel and axicabtagene ciloleucel, as well as the anti-BCMA CART products idecabtagene vicleucel and ciltacabtagene autoleucel. However, bendamustine as lymphodepletion prior to lisocabtagene maraleucel (liso-cel), a 4-1BB co-stimulated, fixed CD4:CD8 ratio anti-CD19 CART product, has not been described yet. Thus, we studied a cohort of sequentially-treated patients with large B-cell lymphomas who received bendamustine lymphodepletion before liso-cel at the University of Pennsylvania between 5/2021 and 12/2023 (n = 31). Patients were evaluated for toxicities and responses. Of note, 7 patients (22.6%) would have dnot met the inclusion criteria for the registrational liso-cel clinical trials, mostly due to older age. Overall and complete response rates were 76.9% and 73.1%, respectively. At a median follow-up of 6.3 months, the 6-month progression-free and overall survival were 59.9% and 91.1%, respectively. Rates of cytokine-release syndrome (CRS) and neurotoxicity (ICANS) of any grade were 9.7% and 9.7%, respectively, with no grade ≥ 3 events. No infections were reported during the first 30 days following liso-cel infusion. Neutropenia ≥ grade 3 was observed in 29.0% of patients; thrombocytopenia ≥ grade 3 occurred in 9.7%. In conclusion, bendamustine lymphodepletion before liso-cel appears to be a strategy that can drive tumor responses while ensuring a mild toxicity profile.

Abstract
ABSTRACT Lymphodepletion (LD) is an integral component of chimeric antigen receptor T-cell (CART) immunotherapies. In this study, we compared the safety and efficacy of bendamustine (Benda) to standard fludarabine/cyclophosphamide (Flu/Cy) LD before CD19-directed, CD28-costimulated CART axicabtagene ciloleucel (axi-cel) for patients with large B-cell lymphoma (LBCL) and follicular lymphoma (FL). We analyzed 59 patients diagnosed with LBCL (n = 48) and FL (n = 11) consecutively treated with axi-cel at the University of Pennsylvania. We also analyzed serum samples for cytokine levels and metabolomic changes before and after LD. Flu/Cy and Benda demonstrated similar efficacy, with complete remission rates of 51.4% and 50.0% (P = .981), respectively, and similar progression-free and overall survivals. Any-grade cytokine-release syndrome occurred in 91.9% of patients receiving Flu/Cy vs 72.7% of patients receiving Benda (P = .048); any-grade neurotoxicity after Flu/Cy occurred in 45.9% of patients and after Benda in 18.2% of patients (P = .031). In addition, Flu/Cy was associated with a higher incidence of grade ≥3 neutropenia (100% vs 54.5%; P < .001), infections (78.4% vs 27.3%; P < .001), and neutropenic fever (78.4% vs 13.6%; P < .001). These results were confirmed both in patients with LBCL and those with FL. Mechanistically, patients with Flu/Cy had a greater increase in inflammatory cytokines associated with neurotoxicity and reduced levels of metabolites critical for redox balance and biosynthesis. This study suggests that Benda LD may be a safe alternative to Flu/Cy for CD28-based CART CD19-directed immunotherapy with similar efficacy and reduced toxicities. Benda is associated with reduced levels of inflammatory cytokines and increased anabolic metabolites.

Abstract
BACKGROUND AND AIMS Diagnosis of fish may represent an important challenge for the allergists. This study aimed to evaluate the diagnostic sensitivity of an in vitro multiplex assay using a comprehensive panel of fish allergens and the cross-reactivity patterns between different molecular components. METHODS 56 subjects with fish allergy were enrolled. All patients underwent specific IgE measurement using the Allergy Explorer-Alex 2™ multiplex assay (Macroarray Diagnostics, Vienna, Austria) RESULTS: The single ß-parvalbumins Clu h 1, Cyp c 1, Gad m 1, Sal s 1, Sco s 1, Thu a 1 and Xyp g 1 scored positive in 75.0%, 67.8%, 62.5%, 80.3%,80.3%, 78.8% and 73,2% patients, respectively. 14.3% scored positive for the α-parvalbumin (Raj c-parvalbumin), and 16.1% for the aldolase + enolase (Gad m 2 + 3) components. 92.8% reacted to at least one ß-parvalbumin and 96.4% to at least one of the allergens tested. Overall sensitivity was higher than that obtained using commercial extracts of cod, salmon and tuna for skin prick test (75.8%) and IgE detection (92.3%). CONCLUSIONS The Alex 2 showed high diagnostic sensitivity and it might be used as an additional assay to investigate the cross-reactivity patterns between different molecular components, looking for potentially safe fish species.

Abstract
Excimer Laser Coronary Atherectomy (ELCA) is a well-established therapy that emerged for the treatment of peripheral vascular atherosclerosis in the late 1980s, at a time when catheters and materials were rudimentary and associated with the most serious complications. Refinements in catheter technology and the introduction of improved laser techniques have led to their effective use for the treatment of a wide spectrum of complex coronary lesions, such as thrombotic lesions, severe calcific lesions, non-crossable or non-expandable lesions, chronic occlusions, and stent under-expansion. The gradual introduction of high-energy strategies combined with the contrast infusion technique has enabled us to treat an increasing number of complex cases with a low rate of periprocedural complications. Currently, the use of the ELCA has also been demonstrated to be effective in acute coronary syndrome (ACS), especially in the context of large thrombotic lesions.

Abstract
The treatment of hairy cell leukemia (HCL) has considerably changed over years. Purine analogues, namely cladribine, now represent the treatment of choice. One hundred and eighty-four patients were followed between 1986 and 2018 and treated according to era-specific guidelines. Responses were classified by combining Consensus Resolution criteria and marrow immunohistochemistry. Patients were grouped according to the number of treatment lines they received. Patients treated first line responded in 86% of cases, with complete response (CR) in 44% of cases. Response rates remained high throughout the first four lines (84%, 81%, 79% for the second line onward, with CR in 38%, 37%, 15% of cases respectively). One hundred and twenty-two patients received cladribine as first line treatment, with a response rate of 86% and a CR rate of 54%. Among the 66 CR patients, 45 (68%) have never received further therapy: 11 patients are in continuous CR between 5 and 10 years after treatment, 14 between 10 and 20 years and three patients at more than 20 years. Median time-to-next treatment (TTNT) for frontline cladribine-treated patients was 8.2 years: partial responders had a significantly shorter median TTNT than CR patients (5.3 years vs median not reached at 25.8 years, p < 0.001). Patients with HCL require subsequent lines of therapy in more than 50% of cases. Purine analogues allow significant response rates when applied first line and upon retreatment. Some patients may enjoy long lasting treatment-free intervals after one course of cladribine.

Abstract
INTRODUCTION Despite significant advances in treatment and prevention, graft-versus-host disease (GVHD) still represents the main cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Thus, considerable research efforts have been made to find and validate reliable biomarkers for diagnosis, prognosis, and risk stratification of GVHD. AREAS COVERED In this review the most recent evidences on different types of biomarkers studied for GVHD, such as genetic, plasmatic, cellular markers, and those associated with microbiome, were summarized. A comprehensive search of peer-review literature was performed in PubMed including meta-analysis, preclinical and clinical trials, using the terms: cellular and plasma biomarkers, graft-versus-host disease, cytokines, and allogeneic hematopoietic stem cell transplantation. EXPERT OPINION In the near future, several validated biomarkers will be available to help clinicians in the diagnosis of GVHD, the identification of patients at high risk of GVHD development and in patients' stratification according to its severity. Then, immunosuppressive treatment could be tailored to each patient's real needs. However, more efforts are needed to achieve this goal. Although most of the proposed biomarkers currently lack validation with large-scale clinical data, their study led to improved knowledge of the biological basis of GVHD, and ultimately to implementation of GHVD treatment.

Abstract
Coaching aims to unlock the human's potential, self-awareness and responsibility, improving the professional performances and the personal satisfaction. Its effectiveness is known to depend on the degree of bonding and mutual engagement of the coaching relationship. In this exploratory study we recorded synchronised EEG and SC data from both coach and coachee during 36 individual sessions, performed following 2 different coaching methods. Our principal aim was to investigate the temporal evolution of the bonding and the mutual engagement along the different steps of a session, by means of a "similarity" metric based on the DTW distance between signals (namely, S-TVM). We found significant differences between session phases for the EEG-related S-TVMs (BAR, BATR and AWI), with maximum values (defined as "tuning") all in the same phase, but differentiated between the two experiments. The results suggest a temporal concurrency of the engagement and emotional tunings, whose specific location seems to be a function of the coaching approach.

Abstract
Summary The clinical usefulness of two commercial peach extracts for SPT (by Lofarma SpA and ALK-Abellò, respectively) was compared in a multicenter study carried out in Italy. Peach allergic patients were tested with the two extracts in parallel and underwent the detection of IgE specific for all three peach allergens currently available (Pru p1, Pru p3, and Pru p4, respectively). The two extracts were almost identical in terms of sensitivity and specificity, being able to detect virtually all patients sensitized to stable peach allergens (lipid transfer protein (LTP) and, presumably, peamaclein) but scoring negative in patients exclusively sensitive to labile allergens (either PR-10 and/or profilin). Thus, the two extracts represent an excellent tool to carry out a preliminary component-resolved diagnosis of peach allergy at the first patient visit.

Abstract
Twelve adults with hepatocellular carcinoma (HCC) and 8 individuals with hystologically normal liver, were measured for serum selenium concentration and glutathione peroxidase (GSH-Px) of liver tissue. It was found a reduced serum selenium and liver GSH-Px in patients with HCC. Serum selenium concentration and the enzyme activity were positively correlated (p < 0.01). The increased risk of carcinoma in selenium deficiency may be partially due to a reduced activity of GSH-Px, one of the most important scavenger enzymes of oxygen toxic radicals.

Abstract
The effects of growing the Saos-2 human osteosarcoma cell line onto surfaces containing -CH(3), -OH, -COOH, -NH(2), and C6H5 groups obtained by silane modification were examined. These cells were used because of the great importance of bone cells in many aspects of biomaterials research. Silane-modified surfaces were characterized by contact angle measurements and, subsequently, surface energies were calculated. Cells grown on clean glass, as well as those grown on glass surfaces containing the functional groups cited above, were examined by light and scanning electron microscopy and assessed for their growth characteristics (i.e., determination of cell number and Ki67 antigen expression). The data presented seemed to indicate that if Saos-2 cells are grown on silane-modifed surfaces containing the methyl (CH(3)), hydroxyl (OH), and phenyl (C6H5) functional groups, their proliferation is slowed down while growth of these cells on glass surfaces modified with amino (NH(2)) and carboxyl (COOH) groups did not significantly affect growth. Once it was demonstrated that these three functional groups induce significant variations in proliferation, cells grown on these surfaces were also tested for apoptosis and expression of important markers of bone cell differentiation (i.e., osteonectin and osteopontin) by flow cytometry and eventual rearrangement of these markers by fluorescence microscopy. The data suggested that growth of Saos-2 cells on CH(3) induces the most evident morphological changes while growth of these cells on OH and C6H5 brings about the greater variations in osteonectin and osteopontin. We hypothesized that these changes are indicative of an increase in differentiation of Saos-2 cells when grown on the OH and C6H5 groups.

Abstract
Studies performed on the interactions and reactions of compounds in the bidimensional state, essentially in monolayers and Langmuir-Blodgett multilayers, with substances in the aqueous subphase are reported. More precisely, the following is illustrated: (i) interactions between acid amphiphiles and prevalently bivalent ions placed in the aqueous support and between compounds capable of functioning like ion carriers in monolayers and ions in the subphase, in order to build mimetic membranes capable of selective ion transport; and the complexation of amphiphiles in monolayer with ions in the bulk liquid phase, in order to build chemical sensors to ions; (ii) the reactions of photoinduced electron transfer between a partner in mono- or multimolecular films and a partner in the subphase, which may determine the fundamental parameters and the differences with the same reactions in the bulk phase; and (iii) the reactions of enzymatic hydrolysis between the monolayer of a glyceride, which constitutes the reaction support, and the enzyme in the liquid bulk phase, which constitutes the subphase. The mechanism of the reactions and its inhibition are clarified. To conclude, possible future developments connected with the areas studied are examined.

Abstract
PURPOSE This prospective, non-randomized study was aimed at evaluating the incidence of Delayed Adverse Drug Reactions (DADRs) to iodinated contrast agents and to evaluate possible risk factors to the development of these reactions. DADRs are those reactions occurring one to 48 hours after contrast medium administration. Their symptoms and frequency are not well defined, but the majority of DADRs are mild in intensity and resolve spontaneously without sequelae. In the literature, DADRs are reported to occur in 1 to 15% of patients undergoing contrast-enhanced examinations. MATERIAL AND METHODS This prospective, non-randomized trial was carried out on 403 patients undergoing either dynamic CT or urography with iopamidol-300 (Iopamiro-300, Bracco SpA). Before the examination, data were collected regarding patients' anagraphical details, presence of risk factors, allergy, previous exposure and previous adverse reactions to iodinated contrast agent. After the examination, any adverse events occurring between 30 minutes and 48 hours post-dose were recorded, specifying time of onset and duration of symptoms. Studied variables were type of DADRs and risk factors to their development (sex, age, underlying disease, allergy, previous exposure to contrast agent, type of diagnostic examination). Two hundred and sixty-two patients were male (65%), and 141 were female (35%). Mean age was 61 years (+/- 11.8); 192 patients (48%) had underlying disease, and 115 (28%) were allergic. About half of the patients had previously undergone another contrast-enhanced examination. Two hundred and seventy-one patients underwent dynamic CT and 132 urography. RESULTS A total of 50 patients (12.4%) reported DADRs. Factors associated with a significantly higher incidence of DADRs were found to be allergy (p = 0.001), previous exposure to contrast agent (p = 0.001), female sex (p = 0.001), underlying disease (p = 0.030). The most frequently reported DADRs were nausea and vomiting, drowsiness, rash, itching and headache. All reported reactions were mild and resolved spontaneously without sequelae. DISCUSSION AND CONCLUSIONS In our experience, though limited and not on large numbers, DADRs to nonionic low osmolality contrast agents such as iopamidol have been few, mild, and not clinically significant. Although there are no absolute contraindications to the use of iodinated contrast agent, the risk/benefit ratio should always be evaluated, especially in patients with allergy, in those with severe renal, hepatic or cardiac insufficiency, and in diabetics.

Abstract
Nitric oxide (NO), a highly diffusible cellular mediator involved in a wide range of biological effects, has been indicated as one of the cytotoxic agents released by leukocytes to counteract malaria infection. On the other hand, NO has been implicated as a mediator of the neuropathological symptoms of cerebral malaria. In such circumstances NO production has been thought to be induced in host tissues by host-derived cytokines. Here we provide evidence for the first time that human red blood cells infected by Plasmodium falciparum (IRBC) synthesize NO. The synthesis of NO (measured as citrulline and nitrate production) appeared to be very high in comparison with human endothelial cells; no citrulline and nitrate production was detectable in noninfected red blood cells. The NO synthase (NOS) activity was very high in the lysate of IRBC (while not measurable in that of normal red blood cells) and was inhibited in a dose-dependent way by three different NOS inhibitors (L-canavanine, NG-amino-L-arginine, and NG-nitro-L-arginine). NOS activity in P. falciparum IRBC is Ca++ independent, and the enzyme shows an apparent molecular mass < 100 kD, suggesting that the parasite expresses an isoform different from those found in mammalian cells. IRBC release a soluble factor able to induce NOS in human endothelial cells. Such NOS-inducing activity is not tissue specific, is time and dose dependent, requires de novo protein synthesis, and is probably associated with a thermolabile protein having a molecular mass > 100 kD. Our data suggest that an increased NO synthesis in P. falciparum malaria can be directly elicited by soluble factor(s) by the blood stages of the parasite, without necessarily requiring the intervention of host cytokines.

Abstract
During cardiac angiography, hemodynamic alterations and surface electrocardiographic changes are common, predictable and dose-related adverse reactions to radiocontrast media. High osmolality, inadequate sodium content and local transient hypocalcemia are thought to be the main mechanisms responsible for these untoward cardiovascular effects. The purpose of this double-blind, parallel-group trial was to compare the hemodynamic and electrocardiographic responses to cardiac and selective coronary artery injection of iomeprol 400 (400 mgI/ml) and iopamidol 370 (370 mgI/ml). One-hundred consenting adult inpatients were randomised to receive iomeprol 400 (41 males, nine females; mean age, 56.6 years) or iopamidol 370 (46 males, four females; mean age, 57.6 years). Both agents produced minor and transient hemodynamic and electrophysiological effects. Following left ventriculography, iopamidol 370 produced a significantly greater increase in LVEDP than iomeprol 400 (mean increases after first and second left ventriculogram: 2.5 and 4.6 mmHg with iomeprol 400, 3.3 and 9.9 mmHg with iopamidol 370, P = 0.027). The QT-interval was more affected by iopamidol 370 than by iomeprol 400. However, post-contrast prolongation of the QT-interval was not significant with either agent, nor were there any significant T-wave, ST-segment or RR-interval changes associated with the injection of the test compounds. No serious adverse events occurred throughout the study. Mild pain was complained by only one patient, while most patients reported mild to moderate sensation of heat. Image quality of the vast majority of the procedures was rated as good or excellent in both patient groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Monolayers and planar or curved bilayers can be considered useful models of biologic membranes. With this in perspective we report on studies performed on monolayers and bilayers of polypeptides and lipids. The results obtained show that the study of monolayers allows either the deduction of the interphasal orientation in a one-component system or the reasons of mutual solubility when mixtures are considered. In the case of bilayers and particularly of BLM, LB films and vesicles, it is possible to gain information about stability and thickness of single component bilayers as well as about the influence of the addition of a second component on these properties. The comparison between the various systems taken into consideration allows us to draw a first conclusion: the condition to form BLM and vesicles is to start from monolayers in expanded phases while the condition to form plurilayers and LB films is to start from monolayers in condensed phases.

Abstract
A standardized Ginkgo biloba L. extract containing flavonol glycosides induces a concentration-dependent relaxation of guinea-pig trachea in vitro and antagonizes in vivo bronchoconstriction induced by various agonists. The action of the extract appears to be mediated partially by an interaction with the eicosanoid system particularly through specific stimulation of the PGE2 biosynthesis and partially by beta-adrenoceptor activation. The relaxation of guinea-pig trachea induced by the extract is in fact antagonized by indomethacin (2 x 10(-8)M), ETYA (3.4 x 10(-8)M) and sotalol (4 x 10(-6)M). The concentration-response curves obtained with tracheal preparation from reserpinized guinea-pig and those performed in the presence of a glutathione depletor (CDNB 1 x 10(-5)M) are modified in a similar manner confirming that the extract can act on both the systems: adrenergic as well as prostaglandinergic.
