The objective of this review is to assess the current state of knowledge of pathogens, general faecal indicators and human-specific microbial source tracking markers in sewage. Most of the microbes present in sewage are from the microbiota of the human gut, including pathogens. Bacteria and viruses are the most abundant groups of microbes in the human gut microbiota. Most reports of this topic show that raw sewage microbiological profiles reflect the human gut microbiota. Human and animal faeces share many commensal microbes as well as pathogens...

In this chapter, a long-term drug delivery system for preclinical therapeutic research is introduced. By using a subcutaneously implanted ALZET® osmotic pump, continuous zero-order delivery of drugs under investigation that need repeated oral or intravenous dosing is realizable. Compared to traditional delivery systems, implanted osmotic pumps present several advantages such as that no external connections or researcher intervention is required during infusion and that it is possible to save time by eliminating the need for frequent animal handling and repetitive injection schedules...

Low-level laser therapy (LLLT) has been promoted for its beneficial effects on tissue healing and pain relief for skin and oral applications. However, there is no corresponding literature reporting on vocal fold wound healing. Our purpose was to assess the potential wound-healing effects of LLLT on primary human vocal fold epithelial cells (VFECs). In this study, normal vocal fold tissue was obtained from a 58-year-old male patient who was diagnosed with postcricoid carcinoma without involvement of the vocal folds and underwent total laryngectomy...

Shigella dysenteriae causing shigellosis is one of the diseases that threaten the health of human society in the developing countries. In Shigella, IpaD gene is one of the key pathogenic genes causing strong mucosal immune system reactions. Anthrax disease is caused by Bacillus anthracis. PA protective antigen is one of the subunits in anthrax toxin complex responsible for the transfer of other subunits into the cytosol of host cells. The 20 kDa subunit of PA (PA20) has the property of immunogenicity. CTxB or B subunit of Vibrio cholerae toxin (CT) is a non-toxic protein and has the function to transfer toxic subunit into cytosol of the host cells by binding to GM1 receptor...

Background Cystic fibrosis-related diabetes (CFRD) is a common comorbidity reported in patients with cystic fibrosis (CF). There is a dearth of data on glucose intolerance or CFRD in children with CF from developing countries. So, we planned to study the prevalence of abnormal glucose tolerance (AGT) in children with CF and its relation with the duration and severity of CF. Methods We performed an oral glucose tolerance test (OGTT) on children (2-18 years old) having CF for at least 6 months. Two-hour plasma glucose levels on OGTT were correlated with various disease-related factors...

Prevotella dentalis is a Gram-negative anaerobic rod involved in various human diseases, especially oral infections. We report a rare case of a pleural effusion due to this microorganism in an elderly patient. An 88-year-old man with chronic respiratory disease presented with a left pleural effusion for more than 1 month. Culture of drained pleural fluid resulted in isolation of P. dentalis. Resistance to penicillin and moxifloxacin was documented. Treatment with drainage and clindamycin was established, but the patient developed cognitive impairment and died after a worsening of his general condition...

DON, NX-3 and butenolide (BUT) are secondary metabolites formed by Fusarium graminearum. Evidence for formation of DON-glutathione adducts exists in plants, and also in human liver (HepG2) cells mass spectrometric evidence for GSH-adduct formation was reported. NX-3 is a DON derivative lacking structural features for Thiol-Michael addition, while BUT has the structural requirements (conjugated double bond and keto group). In the present study, we addressed whether these structural differences affect levels of intracellular reactive oxygen species in HepG2 cells, and if intracellular GSH levels influence toxic effects induced by DON; NX-3 and BUT...

Usage of the amorphous phase of compounds has become the method of choice to overcome oral bioavailability problems related to poor solubility. Due to the unstable nature of glasses, it is clear that the method preparation of the amorphous glass will have an impact on physical/chemical stability and in turn in vivo performance. The method of preparation can also have a profound impact on the mechanical properties of the amorphous phase. We have explored the impact of preparation method on the mechanical properties of an amorphous solid dispersion using a development compound, GDC-0810...

Tongue squamous cell carcinoma (TSCC) is the most common cancers of oral, owing to the high invasive and metastatic ability, patients with TSCC have poor prognosis, it's important to explore the regulatory mechanism of TSCC invasion and metastasis. Previous studies suggest OSR1 suppresses the progression of gastric cancer and renal cell carcinoma, but its role in TSCC hasn't been studied. Here, we found OSR1 was downregulated in TSCC cells and specimens, Transwell and 3D spheroid invasion assay suggested OSR1 overexpression inhibited TSCC cell migration and invasion, while its knockdown promoted TSCC cell migration and invasion...
