PURPOSE Several studies have reported influence of the murine double minute 2 (MDM2) 309T>G polymorphism on head and neck squamous cell carcinoma (HNSCC) susceptibility. However, the results remain controversial and ambiguous. We therefore carried out a meta-analysis to explore more precisely the association between MDM2 309T>G variants and the risk of(More)
We report, for the first time, the identification of fatty acid particles in formulations containing the surfactant polysorbate 20. These fatty acid particles were observed in multiple mAb formulations during their expected shelf life under recommended storage conditions. The fatty acid particles were granular or sand-like in morphology and were several(More)
Prefilled glass syringes (PFSs) have become the most commonly used device for the delivery of recombinant protein therapeutics in parenteral formulations. In particular, auto-injectors preloaded with PFSs greatly facilitate the convenient and efficient self-administration of protein therapeutics by patients. Silicone oil is used as a lubricant in PFSs to(More)
Adsorption of proteins to primary containers can result in protein loss, protein denaturation, or aggregation. We report a simple and effective method to directly detect and visualize adsorption of proteins to container surfaces by staining adsorbed proteins with gold nanoparticles, which bind proteins nonspecifically. The gold nanoparticle staining method(More)
Particle identification is an important analytical procedure for quality control and assurance in the biopharmaceutical industry. Rapid and reliable identification of micro-particles helps in evaluating the nature of particle contamination and its consequences on the product quality regulated by internal and external standards. Raman microscopy is one of(More)
Interleukin-10 (IL-10) plays an important role in a host's defense against human papillomavirus (HPV) infection. IL-10 promoter variants may affect its expression level or functional efficiency and, subsequently, susceptibility to and survival of HPV16-associated squamous cell carcinoma of oropharynx (SCCOP). We determined tumor HPV16 DNA and genotyped(More)
The conformation and local environments of the side chains cysteines and aromatics of recombinant human interleukin-1 receptor antagonist (rh-IL-1ra) have been studied by visible Raman, Raman optical activity (ROA) and UVRR spectroscopy. The results reveal that the secondary structure of rh-IL-1ra is predominantly beta-sheet, which is consistent with(More)
BACKGROUND Non-communicable diseases (NCDs) are showing an increasing trend globally as well as in China. Elderly population are more prone to these NCDs. Situation in China is worse owing to the higher proportion of geriatric population. Burden of NCDs and the role of their socio-demographic and behavioral predictors among these elderly and more so among(More)
BACKGROUND With the gradual aging of the population, geriatric depression has become a major public health issue in China owing to its overall upward trend and associated negative socio-economic impact. Dearth of information regarding the burden and correlates of geriatric depression among Uyghur minority population in Xinjiang Autonomous Region, called for(More)
Simultaneous multiple malignancies of the larynx are rarely reported. In this study, we describe a case with simultaneous laryngeal, moderately differentiated squamous cell carcinoma (SCC) and primary malignant fibrous histiocytoma (MFH) in a patient presenting with progressive hoarseness and without cervical(More)
