Despite being initially considered a benign disease, it is widely thought nowadays that endometriosis and especially ovarian endometriomas are neoplastic conditions with the potential to become malignant. This review was conducted to summarize, in a concise and systematic manner, the available scientific data relating endometriosis to ovarian cancer, published in the past five years. After reading abstracts and applying our predefined inclusion and exclusion criteria, a final list of 11 scientific papers was obtained and subjected to review...

RATIONALE: Thrombomodulin (TBM) is an anticoagulant and anti-inflammatory transmembrane protein expressed on endothelial cells. Donor-specific alloantibodies, particularly those against human leukocyte antigen (HLA) class II, are associated with microvascular endothelial damage in solid allografts. OBJECTIVE: Our aim was to characterize the effects of anti-HLA antibodies on endothelial expression of TBM, and in particular, the differential effects of anti-HLA class I compared with those of anti-HLA class II...

Grapes quality and yield can be impaired by bunch rot, caused by the necrotrophic fungus Botrytis cinerea. Infection often occurs at flowering and the pathogen stays quiescent until fruit maturity. Here, we report a molecular analysis of the early interaction between B. cinerea and Vitis vinifera flowers, using a controlled infection system, confocal microscopy and integrated transcriptomic and metabolic analysis of the host and the pathogen. Flowers from fruiting cuttings of the cv. Pinot Noir were infected with GFP-labeled B...

An 81-year-old female patient was admitted to our institute because of abnormal X-ray results. Chest computed tomography showed a 7.7 × 5.3 cm mass located in the left lower lobe and multiple swollen lymph nodes. 18F-fluorodeoxyglucose-positron emission tomography indicated high standard uptake values in the mass and swollen lymph nodes. The patient was diagnosed with stage cT3N2M0-IIIA squamous cell carcinoma. Although the patient had multiple lymph node metastases and severe obstructive pulmonary function, four cycles of platinum doublet chemotherapy were initially performed and no side effect greater than grade 3 was experienced...

Parkinson's disease is a debilitating neurodegenerative condition for which there is no cure. Converging evidence implicates gangliosides in the pathogenesis of several neurodegenerative diseases, suggesting a potential new class of therapeutic targets. We have shown that interventions that simultaneously increase the neuroprotective GM1 ganglioside and decrease the pro-apoptotic GD3 ganglioside-such as inhibition of GD3 synthase (GD3S) or administration of sialidase-are neuroprotective in vitro and in a number of preclinical models...

Synthesis of mini-size carbon nitride nanosheets (CNNSs) by using traditional ultrasonic method still remains a great challenge. Herein, Size-tunable and uniform mini-size CNNSs are synthesized by hydrothermal carbonization of the single polyethyleneimine (PEI) precursor.The as-obtained mini-size CNNSs possesses uniform size, good hydrophilicity, abundant nitrogen active sites, and not only exhibit double excitation- and pH-depending fluorescence behaviors, but two-photon exitation fluorescence. The resulting CNNSs display relatively low toxicity and can be efficiently delivered into live cells for two-photon fluorescence image, further confirm that the obtained CNNSs can potentially be used as fluorescence probes in biochemical applications...

The primary functions of adrenal medullary chromaffin cells are the synthesis and storage in their chromaffin vesicles of the catecholamines noradrenaline (NA) and adrenaline (AD), and their subsequent release into the bloodstream by Ca(2+) -dependent exocytosis under conditions of fear or stress (fight or flight response). Several monoamines, nucleotides and opiates, such as leucine-enkephalin (LENK) and methionine-enkephalin (MENK), are also co-stored and co-released with the catecholamines. However, other neurotransmitters have not been studied in depth...

BACKGROUND: Lung cancer remains the most common cause of cancer-related death, with high rates of recurrence and poor outcomes. An abnormally high expression of activating transcription factor 3 (ATF3) in various cancers suggests an oncogenic role; however, its function in lung cancer is largely unknown. METHODS: Sixty-four pairs of lung cancer tissues were collected for ATF3 expression analysis by quantitative real-time PCR, immunoblotting, and immunohistochemistry staining...

Siberian sturgeon herpesvirus (SbSHV) was isolated in Russia for the first time in 2006. Nine SbSHV isolates were recovered from different fish hatcheries producing the same cytopathic effect in cell cultures, the same clinical signs and mortality kinetics in virus-infected fish and the same virus neutralization pattern and shared identical nucleotide sequences. In 2011, a new isolate was recovered from juvenile sturgeon, which caused completely different cytopathic effect. That isolate was not readily neutralized by Siberian sturgeon hyperimmune antisera, and its DNA was not recognized by the routine PCR developed for SbSHV detection...

BACKGROUND: Cutaneous lymphomas are a heterogeneous group of tumors with various clinical manifestations, histological features, and prognoses. METHODS: Among 425 cases of cutaneous lymphoma, we describe eight cases of peripheral T-cell lymphoma, unspecified, presenting with generalized benign-looking dermatitis. RESULTS: Our case series included eight cases of secondary cutaneous peripheral T-cell lymphoma, unspecified. The observed clinical morphology features included drug eruption-like generalized morbilliform maculopatches in two cases, generalized folliculitis-like papules in two cases, and generalized eczematous dermatitis-like papules and patches in four cases...

I bought a robotic vacuum cleaner this summer and set it to work. Although my initial expectations were not high, my robot (christened Buddy) finished its cleaning cycle, and then insistently demanded that I empty its dust collection box. As I took the box out, my jaw dropped. I live in a modern house, we don't have pets, and I like to think that I keep it reasonably dust free. But, there was much dust in that box. And when I ran it again 2 days later, the same thing happened. And indeed, every 2 days, Buddy dutifully goes to work, and sucks up a similarly impressive quantity...

Burn injuries are known to compromise host immune defenses through disruption of mucocutaneous barriers and suppression of cell-mediated immune responses, which may render patients with burn injuries susceptible to viral infections in the days to years after an initial insult. We report a case of verrucae planae developing as a secondary condition confined to former xenograft sites in a child, appearing more than 3.5 years after initial second-degree burn injuries. Only a few reports have previously described the development of verrucae in former burn sites, with most reporting latency to onset of verrucae appearance of months rather than years...

BACKGROUND: Merkel cell polyomavirus (MCPyV), a newly described oncogenic virus, has been found in association with tumours other than Merkel cell carcinoma (MCC). As yet, little is known about the involvement or influence of MCPyV on the development of these tumours and its prevalence in various populations. AIM: To assess the prevalence of MCPyV DNA in cases of nonmelanoma skin cancer (NMSC). METHODS: The prevalence of MCPyV DNA was assessed in 96 cases of NMSC in a Brazilian population comprising 76 subjects, and these results were correlated with epidemiological and demographical data...

AIMS: Pharmacokinetic (PK) studies suggest that there is a room for improvement in clinical use of rituximab through more individualized treatment. The objective of this study was to characterize rituximab PK in 29 newly diagnosed patients with diffuse large B-cell lymphoma treated with rituximab in combination with cyclophosphamide, doxorubicin, vincristine and methylprednisolone every three weeks. We also evaluated the association of rituximab PK with clinical outcome. METHODS: Rituximab serum levels were determined by enzyme-linked immunosorbent assay and evaluated by a population PK analysis applying non-linear mixed effects modelling...
