Following a supramolecular synthon rationale, a dicarboxylic acid derivative having a naphthalenediimide (NDI) core, namely, bis-N-carboxymethyl naphthalenediimide (NDI-G), was reacted with n-alkyl amines with varying alkyl chain lengths to generate a new series of primary ammonium dicarboxylate (PAD) salts. The majority of the salts (≈85 %) were found to gel various polar solvents. The gels were characterized by dynamic rheology and high-resolution electron microscopy. Single-crystal and powder X-ray diffraction analyses were used to study the supramolecular synthon present in one of the gelator salts (i...

Pulmonary epithelioid hemangioendothelioma is an uncommon neoplastic disease of endothelial origin, with an incidence inferior to one in a million. It usually behaves as a low-grade malignancy; nevertheless, a few cases have been described in which this tumour manifests a highly aggressive behavior, spreading throughout the organism. We report the case of a 77-year-old woman who was diagnosed with metastatic pulmonary epithelioid hemangioendothelioma with severe symptoms, requiring urgent treatment to palliate them...

PURPOSE: Anaplastic large cell lymphoma (ALCL) is a rare aggresive non-Hodgkin lymphoma, of which over 50% of cases have an aberrant nucleophosmin (NPM)‒anaplastic lymphoma kinase (ALK) fusion protein. Both mechanistic target of rapamycin (mTOR) inhibitor everolimus and ALK inhibitor crizotinib have shown promising antitumor activity in ALK-positive cancer cell lines. However, their combined effect has not yet been investigated. MATERIALS AND METHODS: We evaluated the anti-proliferative effects of everolimus and/or crizotinib in ALK-positive ALCL cell lines, Karpas 299 and SU-DHL-1, and lung adenocarcinoma cell line, NCI-H2228...

BACKGROUND: Angiokeratoma of Fordyce (AF) represents dark red or blue-black papules with a scaly surface located on scrotum, labia majora, and penis. Though usually asymptomatic, bleeding after mechanical trauma and sexual intercourse may occur. AF should be differentiated from malignant melanoma, angiosarcoma, and other pigmented lesions. The treatment, usually asked from patients as the result of anxiety and social embarrassment, should be performed in a non-aggressive manner. OBJECTIVES: To determine the safety and effectiveness of 595-nm variable-pulse pulsed dye laser (VPPDL) with a Dynamic Cooling Device (DCD) in the treatment of AF...

SOX11 overexpression in mantle cell lymphoma (MCL) has been associated with more aggressive behavior and worse outcome. However, SOX11 oncogenic pathways driving MCL tumor progression are poorly understood. Here, we demonstrate that SOX11 binds to regulatory regions of 2 important genes for microenvironment signals in cancer: (C-X-C motif) chemokine receptor 4 ( CXCR4 ) and PTK2 (encoding for focal adhesion kinase [FAK]). Moreover, SOX11+ xenograft and human primary MCL tumors overexpress cell migration and stromal stimulation gene signatures compared with their SOX11- counterparts...

Tumor-associated endothelial cells (TECs) regulate tumor cell aggressiveness. However, the core mechanism by which TECs confer stem cell-like activity to indolent tumors is unknown. Here, we used in vivo murine and human tumor models to identify the tumor-suppressive checkpoint role of TEC-expressed insulin growth factor (IGF) binding protein-7 (IGFBP7/angiomodulin). During tumorigenesis, IGFBP7 blocks IGF1 and inhibits expansion and aggresiveness of tumor stem-like cells (TSCs) expressing IGF1 receptor (IGF1R)...

For the first time, spatially resolved quantitative metrics of light scattering recovered with sub-diffusive spatial frequency domain imaging (sd-SFDI) are shown to be sensitive to changes in intratumoral morphology and viability by direct comparison to histopathological analysis. Two freshly excised subcutaneous murine tumor cross-sections were measured with sd-SFDI, and recovered optical scatter parameter maps were co-registered to whole mount histology. Unique clustering of the optical scatter parameters μs' vs...

Rhabdomyosarcoma (RMS) is an aggressive soft tissue cancer characterized by disturbed myogenic differentiation. Here we report a role for the oxidative stress response factor HO-1 in progression of RMS. We found that HO-1 was elevated and its effector target miR-206 decreased in RMS cell lines and clinical primary tumors of the more aggressive alveolar phenotype (aRMS). In embryonal RMS (eRMS), HO-1 expression was induced by Pax3/7-FoxO1, an aRMS hallmark oncogene, followed by a drop in miR-206 levels. Inhibition of HO-1 by tin protoporphyrin (SnPP) or siRNA downregulated Pax3/7-FoxO1 target genes and induced a myogenic program in RMS...

Despite the recent findings concerning pathogenesis and novel therapeutic strategies, the mortality rate in patients with acute kidney injury (AKI) remains very high. Early detection of patients with impaired renal function may help to ensure more aggresive treatment and to improve clinical outcome. Serum creatinine is still gold standard of kidney injury, although it is well known as an insensitive and unreliable biomarker (for example, its concentration does not increase significantly until about half of the kidney function is lost)...

Merkel cell carcinoma (MCC) is a rare, agressive, neurocutaneous malignancy with a high potential to metastasize. We present a 59 year-old woman referred to general surgery department with a complaint of epigastric pain. The abdominal computed tomography (CT) performed and revealed amass of 3 cm in the head of the pancreas. The significant debate in the patient's medical history was that she had a MCC in size of 5 cm removed from the left gluteal region 7 months ago. Following preoperative preparation a pancreatic oduodenectomy with Whipple procedure was performed fort hepancreatic head mass...
