A myxozoan parasite belonging to the genus Thelohanellus Kudo, 1933 (Cnidaria, Myxosporea, Bivalvulida) was isolated from the fins of Labeo dero inhabiting Ranjit Sagar Wetland, Punjab, India. The plasmodium was 0.5-0.7 mm in diameter each containing 80- 100 number of myxospores. Myxospores were egg shaped to ovoidal in valvular view having bluntly pointed anterior and broad rounded posterior end measuring 8.36x 4.77 µm. Polar capsule was single, broadly pyriform in shape, measuring 4.77x3.98 µm in size containing a polar filament coiled perpendicular to the longitudinal axis of myxospore body making 7-9 turns...

Particulate matter with aerodynamic diameter ≤2.5 μm (PM2.5 ) is generally composed of carbon nuclei associated with various organic carbons, metals, ions and biological materials. Among these components, polyaromatic hydrocarbons (PAHs) such as benzo(a)pyrene (BaP) and quinones have detrimental effects on airway epithelial cells and immunodisrupting effects, which leads to the exacerbation of respiratory allergies. The effects of PAHs and the carbon nuclei, separately as well as in combination, remain to be established...

Since osteoblastic activities are believed to be coupled with osteoclasts, we have attempted to histologically verify which of the distinct cellular circumstances, the presence of osteoclasts themselves or bone resorption by osteoclasts, is essential for coupled osteoblastic activity, by examining c-fos(-/-) or c-src(-/-) mice. Osteopetrotic c-fos deficient (c-fos(-/-)) mice have no osteoclasts, while c-src deficient (c-src(-/-)) mice, another osteopetrotic model, develop dysfunctional osteoclasts due to a lack of ruffled borders...

Akt2 is an isoform of Akt, and an association between Akt2 and resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has been suggested in pancreatic cancer (PC) in vitro. In this study, we investigated the association between Akt2 expression as evaluated using immunohistochemistry and the outcome of patients with advanced PC who had received treatment with erlotinib (an EGFR-TKI). Although the difference was not significant, patients with high levels of Akt2 expression tended to have a poorer response and a shorter progression-free survival period after treatment with erlotinib plus gemcitabine than those with low expression levels (P=0...

Because of the rarity of hepatic vein tumor thrombus (HVTT), compared with portal vein tumor thrombus (PVTT), in patients with hepatocellular carcinoma (HCC), little is known about this disease entity. The aim of this study was to evaluate the prognosis of each treatment modality for HVTT through an analysis of data collected in a Japanese nationwide survey. We analyzed data for 1,021 Child-Pugh A HCC patients with HVTT without inferior vena cava invasion registered between 2000 and 2007. Of these patients, 540 patients who underwent liver resection (LR) and 481 patients who received other treatments were compared...

BACKGROUND: For patients with advanced hepatocellular carcinoma, sorafenib is the only approved drug worldwide, and outcomes remain poor. We aimed to assess the safety and efficacy of nivolumab, a programmed cell death protein-1 (PD-1) immune checkpoint inhibitor, in patients with advanced hepatocellular carcinoma with or without chronic viral hepatitis. METHODS: We did a phase 1/2, open-label, non-comparative, dose escalation and expansion trial (CheckMate 040) of nivolumab in adults (≥18 years) with histologically confirmed advanced hepatocellular carcinoma with or without hepatitis C or B (HCV or HBV) infection...

We assessed parameters of advanced diffusion weighted imaging (DWI) models for the prediction of the tumor growth rate in 55 head and neck squamous cell carcinoma (HNSCC) patients. The DWI acquisition used single-shot spin-echo echo-planar imaging with 12 b-values (0-2000). We calculated 14 DWI parameters using mono-exponential, bi-exponential, tri-exponential, stretched exponential and diffusion kurtosis imaging models. We directly measured the tumor growth rate from two sets of different-date imaging data...

AIM: The most frequent recurrence site of papillary thyroid carcinoma (PTC) is the cervical lymph nodes. The introduction of an electric linear probe for use with ultrasonography in 1996 improved preoperative lateral neck evaluations. Before 2006, however, our hospital routinely performed prophylactic modified neck dissection (p-MND) for N0 or N1a PTCs >1 cm to prevent node recurrence. In 2006, we changed our policy and the indications for p-MND to PTCs >3 cm and/or with significant extrathyroid extension...

Ultrasonic atomization is used to produce fine liquid mists with diameter ranges below 100nm. We investigated the effect of the frequency on the size distribution of ultrasonic mist. A bimodal distribution was obtained for the mist generated by ultrasonic atomization with a wide-range particle spectrometer. The peak diameter decreased with increasing frequency, and the number concentration of the mist increased in the smaller range. We determined the relation between the size distribution of the mist and the ultrasonic frequency, and we proposed a generation mechanism for the ultrasonic nanosized mist based on the amount of water vapor around the liquid column...

BACKGROUND: Treatment of unresectable malignant hilar biliary stricture (UMHBS) is challenging, especially after failure of repeated transpapillary endoscopic stenting. Endoscopic ultrasonography-guided intrahepatic biliary drainage (EUS-IBD) is a recent technique for intrahepatic biliary decompression, but indications for its use for complex hilar strictures have not been well studied. The aim of this study was to assess the feasibility and safety of EUS-IBD for UMHBS after failed transpapillary re-intervention...

Fas-mediated apoptosis contributes to physiological and pathological cellular processes, such as differentiation and survival. In particular, the roles of Fas in immune cells are complex and critical for the maintenance of immune tolerance. The precise pathways and unique functions associated with Fas/FasL-mediated signaling in the immune system are known. The dual character of Fas/FasL-mediated immune regulation that induces beneficial or harmful effects is associated with the onset or development of immune disorders...

Clinical studies have shown that metabolic disorders such as type 2 diabetes and dyslipidemia are associated with increased risk of oral-related diseases, such as periodontitis and Sjögren's syndrome. Although changes in the immune system are critical in both of these metabolic disorders and oral-related diseases, the mechanism underlying the interaction between these diseases remains largely unknown. Obesity and type 2 diabetes are known to be associated with higher concentrations of free fatty acids in blood...

Approximately 10% of patients with T1 colorectal cancer have lymph node metastases (LNM), requiring node dissection along with surgical resection. Patient gender was recently reported to affect the occurrence of LNM. The aim of the present study was to assess whether patient gender was predictive of LNM in T1 colorectal cancer. Public databases, including PubMed, EMBASE and the Cochrane Central Register of Controlled Trials were searched, using key terms related to 'T1 colorectal cancer' and 'lymph node'. All relevant studies reporting the adjusted odds ratio or risk ratio of LNM in relation to patient gender were included...

IL-33 is one of the critical cytokines that activates group 2 innate lymphoid cells (ILC2s) and mediates allergic reactions. Accumulating evidence suggests that IL-33 is also involved in the pathogenesis of several chronic inflammatory diseases. Previously, we generated an IL-5 reporter mouse and revealed that lung IL-5-producing ILC2s played essential roles in regulating eosinophil biology. In this study, we evaluated the consequences of IL-33 administration over a long period, and we observed significant expansion of ILC2s and eosinophils surrounding pulmonary arteries...

The brain level of perfluorododecanoic acid (PFDoA) was compared with those of perfluorooctanoic acid (PFOA) and perfluorodecanoic acid (PFDA) in rats 9 days after a single oral dose (50 mg/kg). The PFDoA level in the brain was 44.0 ± 2.0 [mu]g/g, which was higher than that in the serum (24.4 ± 1.0 [mu]g/ml). By contrast, the concentrations of PFOA and PFDA in the brain were low (<0.8 and 4.7 ± 0.4 [mu]g/g, respectively), and less than one-tenth of those in the serum. Next, to investigate the effects on brain function, the cognitive function alterations of PFOA, PFDA, and PFDoA were estimated by the novel object recognition test 5-6 days after dosing...
