We report the synthesis of multivalent oleanolic acid (OA) protein conjugates as nonglycosylated neomucin mimic for the capture and entry inhibition of influenza viruses. Oleanolic acid derivatives bearing an amine-terminated linker were synthesized by esterification of carboxylic acid and further grafted onto the human serum albumin (HSA) via diethyl squarate method. The binding of hemagglutinin (HA) on the virion surface to the synthetic neomucin was evaluated by hemagglutination inhibition assay. The influenza virus capture ability of the PEGylated OA-HSA conjugate was further investigated by Dynamic Light Scattering (DLS), virus capture assay and Isothermal Titration Calorimeter (ITC) techniques...

Personalized targeted therapy has emerged as a promising strategy in lung cancer treatment, with current attention focused on elucidation and detection of oncogenic drivers responsible for tumor initiation and maintenance and development of drug resistance. In lung cancer, several oncogenic drivers have been reported, triggering the application of tyrosine kinase inhibitors (TKIs) to target these dysfunctional genes. The anaplastic lymphoma kinase (ALK) rearrangement is responsible for about 4-7% of all non-small cell lung cancers (NSCLCs) and perhaps as high as a third in specific patient populations such as younger, male, non-smokers with advanced stage, epidermal growth factor receptor (EGFR) and Kirsten rat sarcoma viral oncogene (KRAS) wild type, and signet ring cell adenocarcinoma with abundant intracytoplasmic mucin...

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas has a high risk of progressing to invasive pancreatic ductal adenocarcinoma (PDA), but experimental models for IPMN are largely missing. New experimental systems for the molecular characterization of IPMN and for personalized prognosis and treatment options for IPMN are urgently needed. We analyzed the potential use of fertilized chicken eggs for the culture of freshly resected IPMN tissue. We transplanted 49 freshly resected IPMN tissues into eggs and compared the growth characteristics to IPMN tissues transplanted into mice; this was followed by an analysis of histology, morphology and marker expression...

BACKGROUND: Polycystic ovary syndrome (PCOS), and one if its distinguishing characteristics, oligomenorrhea, have both been associated with ovarian cancer risk in some but not all studies. However, these associations have been rarely been examined by ovarian cancer histotypes which may explain the lack of clear associations reported in previous studies. METHODS: We analyzed data from 14 case-control studies including 16,594 women with invasive ovarian cancer (n=13,719) or borderline ovarian disease (n=2,875) and 17,718 controls...

BACKGROUND: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS) which initiated and mediated by autoreactive T helper1 cells directed against myelin antigens. One of T cell surface receptors is T cell immunoglobulin and mucin domain (TIM) family which its importance in immunology is recently discovered. These molecules have important immunological function by regulation of T effector cells. METHODS: In the present study, we analyzed the frequency of +4259A>C polymorphism in TIM-3 and -1637C>T polymorphism in TIM-1 gene in MS patients and healthy controls using restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) method...

A healthy 50-year-old woman had a tattoo performed on the posterior aspect of her neck and another on the dorsum of her left foot. Several weeks later, she noted redness, tenderness, and intense pruritis at both tattoo sites. Treatment with cephalexin and hydrocortisone cream was instituted, without success. Within a few months, the red, but not black, pigment had disappeared from both tattoos and was replaced by pale areas of scarring. Persistently enlarged left supraclavicular and suboccipital lymph nodes were excised 7 and 10 months after receipt of the tattoos, respectively...

AIM: The potential of biomarkers in detecting early cholangiocarcinoma (CCA) is facilitated by examining CCA-associated proteins from primary studies. One such protein is mucin 5AC (MUC5AC) but inconsistency of reported associations between its expression/serum levels and CCA prompts a meta-analysis to obtain more precise estimates. METHODS: A literature search yielded 17 included articles where multiple data in some raised the number of studies to 22. We calculated pooled odds ratios (OR) and 95% confidence intervals from negative and positive readings of MUC5AC levels...

Ovarian cancer is a major gynaecological cancer with different subtypes and studies have suggested that estrogen receptor (ER) or progesterone receptor (PR) positivity are associated with better clinical outcomes. Furthermore, the clinical outcomes of ovarian cancer are better in Asian compared to Caucasian. To date, studies investigating the ER or PR positivity in all subtypes of ovarian cancer, including borderline epithelial, are limited. In this retrospective study we investigated ER and PR positivity in Chinese women with malignant epithelial ovarian cancer (n=577), sex cord-stromal tumor (n=26) and borderline epithelial ovarian cancer (n=98) taking into account menopausal status...

Programmed death-ligand 1 (PD-L1) plays an essential protein for immune evasion, contributing to tumor development and progression. Recent studies have reported MET as an upregulator for PD-L1 overexpression through an oncogenic pathway. However, an association between PD-L1 expression with MET has not been reported in gastric cancer.The prognostic significance of PD-L1 and its association with Epstein-Barr virus (EBV), microsatellite instability (MSI), and mucin phenotype remain controversial. We performed in situ hybridization for EBV-encoded RNA and immunohistochemistry in tissue microarrays for 394 gastric cancers...

Previous studies have shown that the prognosis of lung adenocarcinoma is associated with pathological characterization. In this study, we investigated whether pathology-based prognosis was further influenced by both tumor stage and oncogenic driver mutations. To this end, we recruited a cohort of 465 lung adenocarcinoma patients in China. These patients were classified into 6 pathology-defined subtypes i.e., lepidic-predominant adenocarcinoma (LPA), acinar-predominant adenocarcinoma (APA), papillary-predominant adenocarcinoma (PPA), micropapillary-predominant adenocarcinoma (MPA), solid-predominant adenocarcinoma (SPA), and invasive mucinous adenocarcinoma (IMA)...

Several studies have demonstrated the beneficial impact of dried peas and their components on glucose tolerance; however, the role of gut microbiota as a potential mediator is not fully examined. In this study, we investigated the effect of dietary supplementation with raw and cooked pea seed coats (PSC) on glucose tolerance, microbial composition of the gut, select markers of intestinal barrier function, and short chain fatty acid profile in glucose intolerant rats. Male Sprague Dawley rats were fed high fat diet (HFD) for six weeks to induce glucose intolerance, followed by four weeks of feeding PSC-supplemented diets...
