Malignant melanoma is one of the most common malignant diseases of the gastrointestinal tract. It has been reported that the malignant melanoma metastasizes not only to the small intestine due to the abundant blood supply, but also to the stomach, colon, and esophagus. Gastrointestinal metastasis is usually suspected depending on the clinical symptoms, as well as based on radiological or endoscopic findings. Imunohistochemical stains, such as Melan-A/Melanoma antigen recognized by T cell-1 or human melanoma black-45, are useful for confirming the diagnosis of malignant melanoma...

Periodontitis is a progressive inflammatory disease initiated by bacterial biofilm adhering to the tooth surface. If left untreated, periodontitis may lead to tooth loss and destruction of the alveolar bone. Regaining the lost alveolar bone is a clinical challenge because of the limited differentiation ability of osteoblasts in inflammatory environments. We have previously shown the anti-inflammatory and antiosteoclastogenic activities of parthenolide (PTL) in human periodontal ligament-derived cells by inhibiting nuclear factor kappa B (NF-κB) signaling, indicating its potential for periodontitis treatment...

Hemangiomas of the rib are extremely rare benign neoplasm. Here we present a case in a 47-year-old female, detected by chest X-ray and underwent a surgical resection. Histologically, the tumor was composed of a homogeneous conglomerate, irregular, thin walled and dilated blood vessels containing red blood cells, supported by fibrous stroma and intermingled to regular bone trabeculae. The postoperative courses were uneventful, and there was no recurrence during 64 months follow-up.

As already proven in solid tumors, increased angiogenesis leads to increased number of blood vessels, resulting in unfavorable outcomes and resistance to chemotherapy. It was previously thought that angiogenesis plays no role in the pathogenesis of acute myeloid leukemia (AML), due to the fact that AML is a liquid tumor. However, many studies have suggested that increased angiogenesis has important roles in patients with AML, including increased numbers of vessels in bone marrow and pro-angiogenic factors, as well as decreased anti-angiogenic factors...

Nontuberculous mycobacteria (NTM), including Mycobacterium avium complex (MAC), cause opportunistic chronic pulmonary infections. Notably, MAC susceptibility is regulated by various factors, including the host immune system. Persimmon (Ebenaceae Diospyros kaki Thunb.) tannin is a condensed tannin composed of a polymer of catechin groups. It is well known that condensed tannins have high antioxidant activity and bacteriostatic properties. However, it is hypothesized that condensed tannins might need to be digested and/or fermented into smaller molecules in vivo prior to being absorbed into the body to perform beneficial functions...

Background: Hibernoma is a rare benign tumor of adults that is composed of multivacuolated adipocytes resembling brown fat cells. Hibernoma typically occurs in soft tissue, and intraosseous examples are very rare. Intraosseous hibernomas can radiologically mimic metastatic carcinoma and other tumorous conditions. Materials and Methods: To collect the intraosseous hibernomas, we searched the pathologic database and reviewed the hematoxylin and eosin (H&E)‒stained slides of bone biopsy samples performed to differentiate radiologically abnormal bone lesions from 2006 to 2016...

Uterine fibroids are benign uterine smooth muscle tumors that are present in up to 8 out of 10 women by the age of 50. Many of these women experience symptoms such as heavy and irregular menstrual bleeding, early pregnancy loss, and infertility. Traditionally believed to be inert masses, fibroids are now known to influence endometrial function at the molecular level. We present a comprehensive review of published studies on the effect of uterine fibroids on endometrial function. Our goal was to explore the current knowledge about how uterine fibroids interact with the endometrium and how these interactions influence clinical symptoms...

PURPOSE: Solitary plasmacytoma (SP) is a rare plasma-cell neoplasm, which can develop both in skeletal and/or soft tissue and frequently progresses to multiple myeloma (MM). Our aim was to study the metabolic behavior of SP and the role of 18F-FDG-PET/CT in predicting progression to MM. MATERIALS AND METHODS: Sixty-two patients with SP who underwent 18F-FDG-PET/CT before any treatment were included. PET images were qualitatively and semiquantitatively analyzed by measuring the maximum standardized uptake value body weight (SUVbw), lean body mass (SUVlbm), body surface area (SUVbsa), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and compared with age, sex, site of primary disease, and tumor size...

MicroRNA (miR)-122 functions as a tumor suppressor in various human cancers. However, its involvement in childhood acute myeloid leukemia (AML) remains unknown. In this study, quantitative real-time PCR assay demonstrated that miR-122 expression in bone marrow specimens from AML children were significantly lower than that in non-malignant controls (P<0.001). Statistically, AML children with low miR-122 expression more frequently had large white blood cell count (P=0.022), French-American-British classification subtype M7 (P<0...

Ferritin nanocages are of particular interest as a novel platform for drug and vaccine delivery, diagnosis, biomineralization scaffold and more, due to their perfect and complex symmetry, ideal physical properties, high biocompatibility, low toxicity profiles as well as easy manipulation by genetic or chemical strategies. However, a short half-life is still a hurdle for the translation of ferritin-based nanomedicines into the clinic. Here, we developed a series of rationally designed long circulating ferritin nanocages (LCFNs) with 'Intrinsically Disordered Proteins (IDP)' as a stealth layer for extending the half-life of ferritin nanocages...

Ribosomopathies comprise a heterogeneous group of hematologic and developmental disorders, often characterized by bone marrow failure, skeletal and other developmental abnormalities and cancer predisposition. They are associated with mutations and/or haplo-insufficiencies of ribosomal proteins (RPs) and inefficient ribosomal RNA (rRNA) processing. The resulting ribosomal stress induces the canonical p19ARF/Mdm2/p53 tumor suppressor pathway leading to proliferative arrest and/or apoptosis. It has been proposed that this pathway is then inactivated during subsequent neoplastic evolution...

Enumerating circulating tumor cells (CTCs) in blood and disseminated tumor cells (DTCs) in bone marrow has shown to be clinically useful, as elevated numbers of these cells predict poor clinical outcomes. Accurate detection and quantification is, however, difficult and technically challenging because CTCs and DTCs are extremely rare. We have developed a novel quantitative detection method for enumeration of CTCs and DTCs. Our approach consists of two steps: (1) EPCAM-based immunomagnetic enrichment followed by (2) flow cytometry (IE/FC)...

The purpose of this study is to investigate the effect of TSAHC [4'-(p-toluenesulfonylamido)-4-hydroxychalcone] in K/BxN serum transfer arthritis model and fibroblast-like synoviocytes of rheumatoid arthritis (RA-FLS). In in vivo experiments, TSAHC attenuated the incidence and severity of arthritis in comparison with the vehicle group. Histological findings showed that TSAHC decreased the inflammation, bone erosion, cartilage damage, and osteoclasts activity in the ankle. Furthermore, we confirmed by biochemical analysis that the observations were associated with the decreased expression of proinflammatory cytokines, matrix metalloproteinases (MMPs), and RANKL in serum and ankle...

INTRODUCTION: Hemangiomas are benign tumors characterized by proliferation of blood vessels. A few hemangiomas are aggressive, characterized by bone expansion and extraosseous extension. These benign tumors may be mistaken for metatasis resulting in unnecessary biopsies, which have a high risk of hemorrhage. These hemangiomas can spread not just into the paraspinal soft tissues but also into the epidural region of the spinal canal causing cord compression and paraparesis. These clinical symptoms can be relieved by surgical decompression of the posterior elements, embolization or radiotherapy...

Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. Clinically, this cancer is characterized by the presence of severe primary hyperparathyroidism. Diagnosis is based on histological examination but is not always easy. Surgery is the treatment of choice. We report the case of a 59-year old woman with a personal history of arterial hypertension and of recurrent renal lithiasis, presenting with diffuse bone pain associated with asthenia. Neck examination showed hard basi-cervical swelling with nonpalpable lower edge...
