Development and evaluation of a bivalent vaccine based on recombinant newcastle disease virus expressing infectious bursal disease virus VP2L-CH3-CH4 in SPF chickens.

Newcastle disease (ND) and infectious bursal disease (IBD) are two viral infectious diseases that are extremely damaging to the poultry industry and are widespread throughout the world. It is necessary to develop a safe and effective vaccine against IBD and ND because vaccination is an effective preventive measure. It has been discovered that recombinant proteins expressed by an expression system in which a fragment of mammalian Immunoglobulin G (IgG) Fragment crystallizable (Fc) is linked to a segment of a gene have antibody-like properties that increase the exogenous protein's serum half-life.

Catalyst- and solvent-free approach to 2-arylated quinolines [5 + 1] annulation of 2-methylquinolines with diynones.

A novel route for the synthesis of 2-arylated quinolines through a [5 + 1] annulation directly from 2-methylquinolines and diynones under catalyst-free and solvent-free conditions was disclosed. This synthetic process was atom-economic, with good tolerance of a broad range of functional groups, and with great practical worth.

Fast determination of alkylphenol ethoxylates in leafy vegetables using a modified quick, easy, cheap, effective, rugged, and safe method and ultra-high performance supercritical fluid chromatography-tandem mass spectrometry.

In the present study, a quick and sensitive method was developed for simultaneous determination of nonylphenol ethoxylates (NPxEOs) and octylphenol ethoxylates (OPxEOs) (x=2-20) in three leafy vegetables, including cabbage, lettuce, and spinach using a modified "QuEChERS" method and ultra-high performance supercritical fluid chromatography-tandem mass spectrometry (UHPSFC-MS/MS) with scheduled multiple reaction monitoring (MRM). Under optimized conditions, the 38 target analytes were analyzed within a short period of time (5 min). The linearities of the matrix-matched standard calibrations were satisfactory with coefficients of determination (R)>0.

Ti-O-N/Ti composite coating on Ti-6Al-4V: surface characteristics, corrosion properties and cellular responses.

To enhance the corrosion resistance of Ti-6Al-4V and extend its lifetime in medical applications, Ti-O-N/Ti composite coating was synthesized on the surface via plasma immersion ion implantation and deposition (PIIID). Surface morphology and cross sectional morphology of the composite coating were characterized using atomic force microscopy and scanning electron microscopy, respectively. Although X-ray photoelectron spectroscopic analysis revealed that the Ti-O-N/Ti composite coating was composed of non-stoichiometric titanium oxide, titanium nitride and titanium oxynitride, no obvious characteristic peak corresponding to the crystalline phases of them was detected in the X-ray diffraction pattern.

[The value of ultrasound in diagnosis of IgG4-related sialadenitis].

Purpose: To study the ultrasonic manifestation of IgG4-related sialadenitis, and improve sonographers' understanding of this disease.

Methods: Based on the clinical serological test and histopathologic diagnosis, the features were evaluated by sonography in 25 cases of IgG4-related sialadenitis, including the shape and border of the gland, internal echo texture, presence and distribution of vascularity, duct dilatation, presence/absence of calculi and submandibular lymph nodes. The changes on ultrasonography in 14 patients with IgG4-related sialadenitis before and after steroid treatment were evaluated.

Sarcomatoid carcinoma involving the nasal cavity and paranasal sinus: a rare and highly progressive tumor.

Sarcomatoid carcinoma of nasal cavity and paranasal sinuses is an extremely rare malignant neoplasm. We report a case of sarcomatoid carcinoma arising in the left-side nasal cavity and paranasal sinuses in a 65-year-old man who was hospitalized for left-side nasal epistaxis, odor sensation. Histopathologic examination revealed the tumor was composed of pleomorphic spindle and round cells with frequent mitosis, and no carcinomatous component was recognized.

[Roles of microRNAs in allergic airway diseases].

The microRNAs (miRNAs/miRs) are a class of short non-coding RNAs regulating protein translation via mRNAs silencing. Studies have shown that microRNAs play critical roles in allergic diseases, tumors, and infections. The allergic airway diseases are characterized by inflammation and hyperresponsiveness of the respiratory tract.

[The value of age-adjusted D-dimer cut-off value in diagnosing deep vein thrombosis in elderly patients].

Objective: To validate the value of age-adjusted D-dimer combined with clinical probability to confirm or exclude deep vein thrombosis (DVT) in elderly patients.

Method: Elderly patients ( ≥ 65 years) suspected with DVT were evaluated by Wells score and D-dimer test. All patients underwent ultrasonography examination except for patients with Wells score < 2 and negative D-dimer test results.

Predicting early intrahepatic recurrence of hepatocellular carcinoma after microwave ablation using SELDI-TOF proteomic signature.

Background/aims: Despite great progress in the treatment of hepatocellular carcinoma (HCC) over the last-decade, intrahepatic recurrence is still the most frequent serious adverse event after all the treatments including microwave ablation. This study aimed to predict early recurrence of HCC after microwave ablation using serum proteomic signature.

Methods: After curative microwave ablation of HCC, 86 patients were followed-up for 1 year.

Synovial sarcoma of the neck masquerading as a malignant second branchial cleft cyst.

Synovial sarcoma is an uncommon, aggressive malignant tumor of the soft tissues primarily involving the extremities of young adults. Head and neck synovial sarcoma is rare, and its diagnosis and therapy are still challenging.We report a case of a young patient with synovial sarcoma, clinically masquerading as cystic mass of the neck and malignant second branchial cleft cyst.

HOGG1 Ser326Cys polymorphism and susceptibility to head and neck cancer: a meta-analysis.

Purpose: Several research groups have investigated the influence of the human 8-oxoguanine DNA glycosylase 1 (hOGG1) Ser326Cys polymorphism on head and neck cancer (HNC) susceptibility. However, the results remain inconclusive and controversial. We therefore conducted the present meta-analysis.

XPA A23G polymorphism and susceptibility to cancer: a meta-analysis.

Xeroderma pigmentosum group A (XPA) participates in modulating recognition of DNA damage during the DNA nucleotide excision repair process. The XPA A23G polymorphism has been investigated in case-control studies to evaluate the cancer risk attributed to the variant, but the results were conflicting. To clarify the effect of XPA A23G polymorphism in cancer risk, we conducted a meta-analysis that included 30 published case-control studies.

Expression of type IV collagen, metalloproteinase-2, metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in laryngeal squamous cell carcinomas.

Objective: To investigate the significance of type IV collagen, metalloproteinase-2 (MMP-2), metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) expression in laryngeal squamous cell carcinomas (LSCCs).

Methods: Expression was quantified in 44 LSCC and 22 adjacent non-cancer normal tissues using a streptavidin-peroxidase conjugated immunohistochemistry and associations between the levels of the four proteins and clinicopathological characteristics in LSCC were analyzed.

Results: Significantly different expression of all four proteins was observed in LSCC and adjacent non-cancer normal tissues (P<0.
