Abstract:

CONTEXT Systemic mastocytosis is defined as a clonal disorder of mast cells and their precursor cells and is currently classified as a myeloproliferative neoplasm. Its clinical course has a wide spectrum, ranging from indolent disease, with normal life expectancy, to highly aggressive disease, associated with multisystemic involvement and poor overall survival. The aim of this study was to report a case of indolent systemic mastocytosis, focusing on the diagnostic challenges, with a review of the literature.

Abstract:

Smoldering multiple myeloma is a heterogeneous asymptomatic precursor to multiple myeloma. Since its identification in 1980, risk stratification models have been developed using two main stratification methods: clinical measurement-based and genetics-based. Clinical measurement models can be subdivided in three types: baseline measurements (performed at diagnosis), evolving measurements (performed over time during follow-up appointments), and imaging (for example, magnetic resonance imaging). Genetic approaches include gene expression profiling, DNA/RNA sequencing, and cytogenetics. It is impo

Abstract:

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is an atypical pulmonary disorder with limited understanding. Given the rare nature of this disease, it is essential to obtain adequate tissue pathology to confirm the diagnosis. This disease is mainly diagnosed in middle-aged, nonsmoking females, and it is now accepted as a precursor lesion to pulmonary carcinoid tumors. DIPNECH presents with characteristic radiographic and histologic findings, but its diagnosis, management, and prognosis are often underrecognized and poorly understood.

Abstract:

Follicular lymphoma (FL), a generally indolent disease that derives from germinal center (GC) B cells, represents around 20–25% of all new lymphomas diagnosed in Western countries. The characteristic t(14;18)(q32;q21) translocation that places the BCL2 oncogene under control of the immunoglobulin heavy-chain enhancer occurs in pro- or pre-B cells. However, additional secondary alterations are required for the development of overt FL, which mainly affects genes involved in epigenetic and transcriptional regulation, signaling and B cell differentiation, the BCR/NF-κB pathway, and proliferation/a

Abstract:

Follicular lymphoma (FL) is the most common indolent B-cell lymphoma and originates from germinal center B-cells (centrocytes and centroblasts) of the lymphoid follicle. Tumorigenesis is believed to initiate early in precursor B-cells in the bone marrow (BM) that acquire the t(14;18)(q32;q21). These cells later migrate to lymph nodes to continue their maturation through the germinal center reaction, at which time they acquire additional genetic and epigeneticabnormalities that promote lymphomagenesis. FLs are heterogeneous in terms of their clinicopathologic features. Most FLs are indolent and

Sprouty proteins are important regulators of ERK/MAPK signaling and have been studied in various cancers.

Abstract Abstract 4798 Blinatumomab is a single-chain bispecific antibody construct with specificity for CD19 and CD3 belonging to the class of bispecific T cell engager (BiTE®). It has shown high response rates as single agent after treatment of patients with indolent and mantle cell lymphoma and B-precursor acute lymphocytic leukemia. We here report from an ongoing phase 1 trial in non-Hodgkin lymphoma patients on transient laboratory findings seen upon start of continuous i.v. infusion of blinatumomab. The vast majority of adverse events (AEs) during 4-8 weeks of infusion occurred within th

Abstract Several RNA binding proteins (RBPs) have been implicated in the progression of chronic myelogenous leukemia (CML) from the indolent chronic phase to the aggressively fatal blast crisis. In the latter phase, expression and function of specific RBPs are altered at transcriptional or post-translational levels by the increased constitutive kinase activity of the BCR/ABL oncoprotein, resulting in enhanced resistance to apoptotic stimuli, growth advantage and differentiation arrest of CD34+ CML blast crisis (CML-BC) progenitors. In the current study, we identified by RIP (RNA immunoprecipit

AbstractThe palladium-catalyzed synthesis of indole/benzofuran-containing diarylmethanes starting from indolylmethyl or benzofuranylmethyl acetates with boronic acids has been investigated. The success of the reaction is influenced by the choice of precatalyst: with indolylmethyl acetates the reaction works well with [Pd(η3-C3H5)Cl]2/XPhos while with benzofuranylmethyl acetates Pd2(dba)3/XPhos is more efficient. The good to high yields and the simplicity of the experimental procedure make this protocol a versatile synthetic tool for the preparation of 2- and 3-substituted indoles and 2-benzo[b

High serum levels of gut-derived uremic toxins, especially p-cresyl sulfate (pCS), indoxyl sulfate (IS) and indole acetic acid (IAA), have been linked to adverse outcomes in patients with chronic kidney disease (CKD).

The aim of the present study was to evaluate the adsorptive effect of sevelamer carbonate on different gut-derived protein-bound uremic toxins or their precursors in vitro, and its impact on the serum levels of pCS, IS and IAA in patients with CKD stage 3b/4.

Abstract Follicular lymphoma (FL) is the second most common non-Hodgkin lymphoma in the Western world, generally characterized by a disseminated disease at diagnosis, an indolent clinical course and recurrent, increasingly chemo-resistant relapses. Overt FL is preceded by an insidious phase of asymptomatic growth and might emerge from common precursor clones (CPCs), evolving over decades, and which might participate to subsequent relapses. Consequently, the cell of origin remains ambiguous. From the clinical standpoint, morphological, histological and molecular evidences all indicate that FL r

Abstract Cancer-associated microenvironment provides to malignant cells the right cocktail of signals to increase survival, reprogram their metabolism and escape the control of the immune system. Nicotinamide phosphoribosyltransferase (NAMPT) is the only human enzyme that metabolizes nicotinamide, the main NAD precursor, in a rate-limiting step in NAD biosynthesis. Beside this canonical activity, NAMPT can be secreted in the extracellular milieu (eNAMPT), where it exerts cytokine/adipokine-like actions in different tumor models, as well as in acute and chronic inflammatory-metabolic diseases.

The larvae of Chrysomelina leaf beetles produce allomones in gland reservoirs into which the required precursors and also the enzymes are secreted from attached gland cells. Hence, the reservoirs can be considered as closed bio-reactors for producing defensive secretions.
