Aging and overnutrition cause obesity in rodents and humans. It is well-known that obesity causes various diseases by producing insulin resistance (IR). Macrophages infiltrate the adipose tissue (AT) of obese individuals and cause chronic low-level inflammation associated with IR. Macrophage infiltration is regulated by the chemokines that are released from hypertrophied adipocytes and the immune cells in AT. Saturated fatty acids are recognized by toll-like receptor 4 (TLR4) and induce inflammatory responses in AT macrophages (ATMs)...

Herein, we present a case of a 76-year-old Caucasian man with a very large fungating, ulcerating mass, involving the right neck and parotid area, which developed while he was being treated for chronic lymphocytic leukemia/small lymphocytic lymphoma. Resection of the fungating right neck tumor, right modified radical neck dissection, and right superficial parotidectomy with flap reconstruction were performed. The final pathological diagnosis was high-grade leiomyosarcoma of the skin and the subcutaneous tissue, with invasion into the skeletal muscle, skin, and soft tissue...

Mucormycosis is a rare opportunistic fungal infection that can implicate cranial sinuses, brain, lungs, gastrointestinal tract and skin. Although it can occur in patients with competent and incompetent immunity such as patients with diabetes mellitus, lymphoma, leukemia and burns, but it has an aggressive, malignant and lethal course in patients with incompetent immunity. To enforce the importance of burn in patients with underlaying diseases such as diabetes, we are going to report a rare case of diabetic burnt patient complicated by right upper extremity myocutaneous mucormycosis...

Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...

The improvement of solubility and/or dissolution rate of poorly soluble natural compounds is an ideal strategy to make them optimal candidates as new potential drugs. Accordingly, the allyl sulfur compounds and omega-3 fatty acids are natural hydrophobic compounds that exhibit two important combined properties: cardiovascular protection and antitumor activity. Here, we have synthesized and characterized a novel formulation of diallyl disulfide (DADS) and α-linolenic acid (ALA) as protein-nanoemulsions (BAD-NEs), using ultrasounds...

A 17-year-old previously healthy female presented with a progressive soft tissue infiltrative process involving the neck and thorax. Extensive diagnostic evaluation including multiple imaging, laboratory, and biopsy studies was nondiagnostic. Due to an urgent need to establish a diagnosis and several previous nondiagnostic biopsies, she was referred to interventional radiology for MRI-guided wire localization immediately prior to open surgical biopsy. Under general anesthesia, wires were placed in the areas of increased T2 signal within the bilateral splenius capitis muscles using intermittent MRI-guidance followed by immediate surgical biopsy down to the wires...

Lymphoproliferative malignancies constitute a wide spectrum of haematological malignancies and their prevalence is widely increasing. Non-Hodgkin lymphomas and Hodgkin disease, frequently involve extranodal soft tissue structures in the head and neck, thorax and abdomen. These malignancies may involve virtually any type of soft tissues to any extent; hence many different imaging manifestations are possible which may mimic other disorders. The imaging characteristics of extranodal lymphomatous soft tissue involvement are described and classified here according to the site of involvement in 6 cases (primary diseases with orbital, muscle, extra testicular, scalp, sinonasal and pachymeningeal/dural involvement)...

Benign prostatic hyperplasia (BPH) is a chronic condition common in older men that can result in bothersome lower urinary tract symptoms. The molecular mechanisms and networks underlying the development and the progression of the disease are still far from being fully understood. BPH results from smooth muscle cell and epithelial cell proliferation, primarily within the transition zone of the prostate. Apoptosis and inflammation play important roles in the control of cell growth and in the maintenance of tissue homeostasis...

Rhabdomyosarcoma, the most common soft tissue malignancy of childhood, is a morphologically variable tumor defined by its phenotype of skeletal muscle differentiation. The diagnosis of rhabdomyosarcoma often relies in part on the identification of myogenic gene expression using immunohistochemical or molecular techniques. However, these techniques show imperfect sensitivity and specificity, particularly in scant tissue biopsies. Here, we expand the toolkit for rhabdomyosarcoma diagnosis by studying the expression of PAX7, a transcriptional regulator of mammalian muscle progenitor cells implicated in the pathogenesis of rhabdomyosarcoma...

Intranodal palisaded myofibroblastoma (IPM) is a benign mesenchymal neoplasm originating from smooth muscle cells and myofibroblasts. The inguinal region is the most common site of this rare tumor. As there are only about 89 such cases reported in the literature, the precise etiology and pathogenesis have yet to be explained adequately. It is characterized by spindle cells, amianthoid fibers, and by the proliferation of hemosiderin-containing histiocytes in the lymph node. A nodular lesion was excised from the inguinal region of a 47-year-old female patient with the clinical diagnosis of lymphoma and/or metastase...

Extranodal lymphoma (ENL) occurs in approximately 30%-40% of all patients with non-Hodgkin lymphoma and has been described in almost all organs and tissues. However, diffuse large B-cell lymphoma is the most common histological subtype of non-Hodgkin lymphoma, primarily arising in the retroperitoneal region. In this article, we report a rare case of an adult male diagnosed with primary diffuse large B-cell lymphoma of the gluteal and adductor muscles with aggressive bone involvement. All appropriate radiological and histopathological studies were done for diagnosis and staging...

Radiation-induced tissue damage is caused by ionizing radiation mainly affecting the skin, vascular, neuronal or muscle tissue. Early damages occur within weeks and months while late damages may occur months or even decades after radiation.Radiation-induced paresis of the spine or the trunk muscles with camptocormia or dropped-head syndrome are rare but have already been described as long-term sequelae after treatment of Hodgkin's lymphoma. The differential diagnosis includes limb-girdle muscular dystrophy, fascioscapulohumeral muscular dystrophy (FSHD) or lysosomal storage diseases (e...

Rhabdomyosarcoma (RMS) is the most frequent soft tissue tumor in childhood and arises from immature mesenchymal cells committed to skeletal muscle differentiation. Anaplastic Lymphoma Kinase (ALK) is a receptor tyrosine kinase aberrantly expressed in several cancers. Moreover, ALK full-length receptor protein has been observed in RMS, although its clinical and functional significance is yet controversial. The role of ALK and its clinical relevance were investigated in a selected cohort of 74 FFPE pediatric RMS and a panel of RMS cell lines, evaluating its gene and protein status, utilizing Fluorescent In Situ Hybridization (FISH), immunohistochemistry (IHC) and Western blot approaches...
