OBJECTIVES: The pathways by which physical activity impacts on participants' health are still not fully understood. The purpose of the present study was to go beyond existing research by combining methods from survey-based and experimental stress research, and by examining whether the potential of vigorous physical activity (VPA) to attenuate physiological and psychological stress responses is moderated by participants' subjective stress perception. METHODS: The sample consisted of 42 undergraduate students (M=21...

Application of road salts in regions with colder climates is leading to ground and surface water contamination. However, we know little about how modern stormwater management practices affect the movement of road salt through urban watersheds. We investigated groundwater contamination and transport of road salts at two stormwater ponds in Baltimore County, Maryland. In association with the ponds, we documented a plume of contaminated groundwater that resulted in Cl- loadings to the adjacent stream of 6,574 to 40,008 kg Cl- per winter, depending on winter snowfall...

BACKGROUND: A fish spike injury can be sustained by anyone handling fish; during fishing, meal preparation or in retail. Case reports of fish spikes inoculating victims with virulent marine-specific pathogens and causing systemic illness led us to question whether empirical treatment of these injuries with amoxicillin and clavulanic acid is adequate. METHODS: This 2-year prospective observational study was conducted at Middlemore Hospital, Auckland, New Zealand...

REVIEW
Lakshman Samaranayake, Victor H Matsubara
The oral ecosystem comprises the oral flora, so-called oral microbiome, the different anatomic microniches of the oral cavity, and its bathing fluid, saliva. The oral microbiome comprises a group of organisms and includes bacteria, archaea, fungi, protozoa, and viruses. The oral microbiome exists suspended in saliva as planktonic phase organisms or attached to oral surfaces as a plaque biofilm. Homeostasis of the plaque biofilm and its symbiotic relationship with the host is critical for oral health. Disequilibrium or dysbiosis within the plaque biofilms is the initiating event that leads to major oral diseases, such as caries and periodontal disease...

Aim. Evaluation of the impact of gut microflora on the pathophysiology of MS. Results. The etiopathogenesis of MS is not fully known. Gut microbiota may be of a great importance in the pathogenesis of MS, since recent findings suggest that substitutions of certain microbial population in the gut can lead to proinflammatory state, which can lead to MS in humans. In contrast, other commensal bacteria and their antigenic products may protect against inflammation within the central nervous system. The type of intestinal flora is affected by antibiotics, stress, or diet...

Cassava brown streak disease (CBSD) is the most important virus disease of cassava and a major food security threat in Africa. Yearly economic losses of up to $100 million USD have been attributed to CBSD. The lack of information on plant-virus interactions has restricted progress in breeding for CBSD resistance. Virus quantification is becoming a major tool for the quick and reliable assessment of plant host resistance. Therefore, a protocol for specific absolute quantification of Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV) was developed...

Extended-spectrum β-lactamases (ESBLs) and plasmid mediated AmpC β-lactamases (pAmpC) are enzymes able to hydrolyze a large variety of β-lactam antibiotics, including 3(rd) generation cephalosporins and monobactams. Broilers and broiler meat products can be highly contaminated with ESBL and pAmpC-producing Escherichia coli, also known as extended-spectrum cephalosporins (ESC)-resistant E. coli, and can be a source for human infections. As few data are available on interventions to reduce ESC-resistant E...

Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in China and manifests as simple fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. Studies have shown that intestinal flora can affect the development and progression of NAFLD via the "gut-liver axis" . Probiotics are active microorganisms with beneficial effects on the host, and more and more studies have found that probiotics play a positive role in improving NAFLD. They are cheaper, less harmful, and safer compared with antibiotics and surgery, and therefore, it may become a new method for the prevention and treatment of NAFLD...

Purpose The major causes of mortality after allogeneic hematopoietic-cell transplantation (allo-HCT) are relapse, graft-versus-host disease (GVHD), and infection. We have reported previously that alterations in the intestinal flora are associated with GVHD, bacteremia, and reduced overall survival after allo-HCT. Because intestinal bacteria are potent modulators of systemic immune responses, including antitumor effects, we hypothesized that components of the intestinal flora could be associated with relapse after allo-HCT...

Human microbiota is a term conventionally used to define the normal flora of microbes living in all of us, most of which are resident in the gastrointestinal tract. Despite it having been known for some time that the vast majority of intestinal bacteria exert a strong influence on human life, recent technologic breakthroughs have made it possible to more accurately characterize the host microbial communities and explore their relationship with many human diseases. Notably, the evidence accumulated over the past 10 years suggests that a reasonable relationship can now be established between gut microbiota composition and the risk of cardiovascular disease...

Some scholars caution that long-term ad libitum feeding with probiotic fermented food poses potential health risks to baby animals. We conducted a feeding experiment to investigate the influence of ad libitum feeding of pre-and post-weaned piglets with a Bacillus subtilis fermented diet on the gut microbiome, gut metabolomic profiles, bile acid metabolism, proinflammatory cytokines and faecal consistency. Compared with piglets fed a Bacillus subtilis-supplemented pellet diet, piglets fed the Bacillus subtilis fermented liquid diet had lower intestinal bacterial diversity (P > 0...

INTRODUCTION: Psoriatic patients on tumor necrosis factor alpha inhibitors (TNFi) may be at increased risk for upper respiratory tract infections, including chronic rhino-sinusitis (CRS). Rarely, CRS can progress to orbital cellulitis (OC), an emergent ophthalmic complication wherein respiratory flora from paranasal sinus disease intrude the retro-orbital space. MATERIALS AND METHODS: Single case report. RESULTS: We report the first case, to our knowledge, of an invasive sinusitis that rapidly evolved into OC in a patient receiving adalimumab treatment for plaque psoriasis and psoriatic arthritis...

(-)-Epigallocatechin 3-O-(3-O-methyl) gallate (EGCG3″Me) has exhibited multiple beneficial effects on the prevention of obesity in oolong tea. However, its absorption is relatively low, and the potential to be fully utilized is not completely elucidated. Therefore, with human flora-associated (HFA) mice model, the effect of EGCG3″Me on high fat diet-induced obesity was investigated by high-throughput sequencing. The shifts in relative abundance of the dominant taxa at the phylum, family and genus levels showed the dramatically effects of EGCG3″Me...
