Effects of extracellular polymeric substances on silver nanoparticle bioaccumulation and toxicity to Triticum aestivum L.

The potential effects of extracellular polymeric substances (EPS) on the behavior and toxicity of silver nanoparticle (Ag-NPs) and silver sulfide nanoparticle (AgS-NPs) remains ambiguous. The interaction of EPS from Bacillus subtilis with AgS-NPs, metallic Ag-NPs, or ionic Ag, and the associated plant safety had been examined in this study. The biological impacts of Ag-NPs and AgS-NPs were Ag form-dependent and highly influenced by microbial EPS.

Bacterial contamination of medical uniforms: a cross-sectional study from Suzhou city, China.

Few studies have been conducted which evaluate the prevalence of contamination of medical uniforms in China. The present study was designed to explore the characteristics of uniform contamination and associated factors. A total of 120 participants were enrolled in the study and 122 uniforms were sampled.

Serum pleiotrophin could be an early indicator for diagnosis and prognosis of non-small cell lung cancer.

Aims: Pleiotrophin (PTN), an angiogenic factor, is associated with various types of cancer, including lung cancer. Our aim was to investigate the possibility of using serum PTN as an early indicator regarding disease diagnosis, classification and prognosis, for patients with non-small cell lung cancer (NSCLC).

Methods: Significant differences among PTN levels in patients with small cell lung cancer (SCLC, n=40), NSCLC (n=136), and control subjects with benign pulmonary lesions (n=21), as well as patients with different pathological subtypes of NSCLC were observed.
