Abstract

ABSTRACT: Paper currency and coins may be a public health risk when associated with the simultaneous handling of food and could lead to the spread of nosocomial infections. Banknotes recovered from hospitals may be highly contaminated by Staphylococcus aureus. Salmonella species, Escherichia coli and S. aureus are commonly isolated from banknotes from food outlets. Laboratory simulations revealed that methicillin-resistant S. aureus can easily survive on coins, whereas E. coli, Salmonella species and viruses, including human influenza virus, Norovirus, Rhinovirus, hepatitis A virus, and Rotavirus, can be transmitted through hand contact. Large-scale, 16S rRNA, metagenomic studies and culturomics have the capacity to dramatically expand the known diversity of bacteria and viruses on money and fomites. This review summarizes the latest research on the potential of paper currency and coins to serve as sources of pathogenic agents.

Abstract

Dental chair units (DCUs) use water to cool and irrigate DCU-supplied instruments and tooth surfaces, and provide rinsewater during dental treatment. A complex network of interconnected plastic dental unit waterlines (DUWLs) supply water to these instruments. DUWLs are universally prone to microbial biofilm contamination seeded predominantly from microorganisms in supply water. Consequently, DUWL output water invariably becomes contaminated by high densities of microorganisms, principally Gram-negative environmental bacteria including Pseudomonas aeruginosa and Legionella species, but sometimes contain human-derived pathogens such as Staphylococcus aureus. Patients and staff are exposed to microorganisms from DUWL output water and to contaminated aerosols generated by DCU instruments. A wide variety of approaches, many unsuccessful, have been proposed to control DUWL biofilm. More recently, advances in biofilm science, chemical DUWL biofilm treatment agents, DCU design, supply water treatment and development of automated DUWL biofilm control systems have provided effective long-term solutions to DUWL biofilm control.

5. The potential role of Akkermansia muciniphilain liver health

Author

Zhang, Min, Wang, Yang, and Gan, Yong

Abstract

ABSTRACTAkkermansia muciniphila(A. muciniphila) is a ‘star strain’ that has attracted much attention in recent years. A. muciniphilacan effectively regulate host metabolism, significantly affect host immune function, and play an important role in balancing host health and disease. As one of the organs most closely related to the gut (the two can communicate through the hepatic portal vein and bile duct system), liver is widely affected by intestinal microorganisms. A growing body of evidence suggests that A. muciniphilamay alleviate liver-related diseases by improving the intestinal barrier, energy metabolism and regulating inflammation through its protein components and metabolites. This paper systematically reviews the key roles of A. muciniphilaand its derivatives in maintaining liver health and improving liver disease.

Abstract

The article offers news briefs involving several pharmaceutical studies in the U.S. A study headed by Jagannath C. Lindsey reveals the significance of autophagy in enhancing the efficacy of BCG vaccine by increasing peptide presentation in mouse dendritic cells. A research headed by R. H. Groenwold determines the effect of influenza vaccination on mortality risk among elderly.

Abstract

The article offers news briefs related to medical research. A study reveals that an adenoviral vector vaccine with the heavy chain C fragment (HC50) of botulinum neurotoxin type C (BoNT/C) has been found effective in treating a mouse suffering from botulism. Another study was conducted which describes the structure of the Ebola virus C-terminal VP35 interferon (IFN) inhibitory domain solved to a resolution of 1.4-Å.

Abstract

The article reports on the two studies related to microbiology conducted by researchers in Great Britain. One study finds that the incorporation of a non-human glycan mediates human susceptibility to a bacterial toxin. Meanwhile, the other study explores on the stimulation of Ebola virus production from persistent infection through activation of the Ras/mitogen-activated protein kinase (MAPK) pathway.

Abstract

The article presents summary of two studies concerning (severe acute respiratory syndrome coronavirus ) SARS-CoV infections and methicillin-resistant Staphylococcus Aureus (MRSA). Accordingly, the first study shows that SARS-CoV strains cannot infect humans because of angiotensin-converting enzyme 2 (ACE-2) and two coronavirus residues. The second study determines the activity of BPR against Staphylococcus aureus, which showed that BPR is effective against all MRSA strains.

Abstract

The article discusses various studies related to microbiology. One study presents a novel real time polymerase chain reaction-based diagnostic assay for the detection of viable bacterial mRNA in human synovial fluid samples. The other study also discusses peptoids that mimic the structure, function, and mechanism of helical antimicrobial peptides.
