Heat stress (HS) causes morbidities and mortalities, in part by inducing organ-specific injury and dysfunction. Further, HS markedly reduces farm animal productivity, and this is especially true for lean tissue accretion. The purpose of this investigation was to determine the extent to which short-term HS caused muscle dysfunction in skeletal muscle. We have previously found increased free radical injury in skeletal muscle following 24 h of HS. Thus, we hypothesized that HS would lead to apoptosis, autophagy, and decreased mitochondrial content in skeletal muscle...

PD-1 and its ligands have been shown to play a significant role in evasion of malignant tumour cells from the immune system. Last year, the Unites States Food and Drug Administration (FDA) approved anti-PD-1 inhibitors for treatment of non-small cell lung carcinoma and recently expanded the use of immunotherapy for metastatic urothelial cell carcinoma and Hodgkin lymphoma. However, studies on expression of PD-1 and its ligand in malignant bone and soft tissue sarcoma are sparse. In this study, we evaluated PD-1 and PD-L1 expression on variants of liposarcomas and rhabdomyosarcomas, osteosarcomas and chondrosarcomas...

BACKGROUND: The inflammatory myopathies are a heterogeneous group of muscle diseases and comprise polymyositis, dermatomyositis (DM), myopathies associated with cancers, necrotising myositis and inclusion body myositis. DM occasionally exhibits few or no muscular signs: i.e. hypomyopathic/amyopathic DM. Anti-MDA5 dermatomyositis (DM) is a rare form of dermatomyositis that is frequently amyopathic; the prognosis is linked mainly to pulmonary involvement. PATIENTS AND METHODS: A 69-year-old woman treated for mucosa-associated lymphoid tissue (MALT) gastric lymphoma was referred for a bullous eruption...

Bcl-2 is a pro-survival member of Bcl-2 like superfamily, playing an important role in regulating the apoptotic process. In this study, the full-length Bcl-2 (EcBcl-2) was obtained, consisting of a 5'UTR of 290 bp, an ORF of 699 bp and a 3'UTR of 920 bp. EcBcl-2 gene encoded a polypeptide of 232 amino acids with an estimated molecular mass of 26.12 KDa and a predicted isoelectric point (pI) of 6.93. The deduced amino acid sequence analysis showed that EcBcl-2 consisted of the conserved residues and characteristic domains known to the critical functionality for Bcl-2...

Histochemical techniques used in examination of muscle biopsies typically require frozen sections. Given that most of the specimens submitted to a veterinary laboratory for diagnosis are formalin-fixed, the choice of staining methods is limited. We aimed to further advance the diagnostic capabilities of pathologists presented with formalin-fixed muscle samples and to describe the differences in immunohistopathologic findings between neurogenic and myogenic muscle disorders. Based on hematoxylin and eosin staining, we defined in dogs the histologic lesions in 4 neurogenic disorders (degenerative myelopathy and polyneuropathy) and 2 myogenic disorders (dystrophin-deficient muscular dystrophy)...

Smooth muscle myosin heavy chain (SMMHC) is a major structural component of the contractile apparatus in smooth muscle cells. Even though it is considered a relatively specific marker for terminal smooth muscle cell differentiation, expression in other cell types such as follicular dendritic cells (FDCs) has rarely been reported. To determine whether SMMHC represents an effective FDC marker in lymphoid tissues, we compared the immunohistochemical results for SMMHC with those of the traditional FDC markers podoplanin (D2-40) and CD21...

PURPOSE OF REVIEW: To review current knowledge regarding diagnosis of nonthyroid orbital disorders with extraocular muscle enlargement. RECENT FINDINGS: Recent publications have focused on immunoglobulin G4-related disease as a possible cause of enlarged extraocular muscles, on patterns of strabismus that raise a clinical suspicion of intramuscular lymphoma, and on surgical techniques to access the muscles for tissue biopsy. SUMMARY: With enlarged extraocular muscles, features to distinguish between competing diagnostic possibilities are based on imaging in the context of history and clinical signs...

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)...

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...

Curcumin is a natural polyphenol with powerful antioxidant and anti-inflammatory properties. The present study evaluated the protective effect of curcumin on myocardial injury in rats as well as the mechanisms underlying these effects, and examined the expression of nuclear factor-κB (NF-κB), peroxisome proliferator-activated receptor-γ (PPAR-γ) and B-cell leukemia/lymphoma-2 (Bcl-2) following myocardial infarction. A rat model of myocardial infarction was successfully established. Hematoxylin and eosin staining showed cellular atrophy and hyperchromatic cytoplasm in the myocardial infarction area...

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...
