Do Probiotics Protect Against the Deleterious Effects of a High-Fat Diet?
High-fat diets and obesity have been linked to unfavorable changes in gut bacteria and increased leakage of bacterially-derived lipopolysaccharide (endotoxin) from the intestinal tract into circulation, which is associated with low-grade inflammation, metabolic dysregulation and degradation of …

The tensile performance of closed cell foam expansion joints: a study on the deleterious effects of compression set
… the bonded specimens had significant detrimental effects on the tensile performance of the foam, implying that improper installation is a more likely cause for limited tensile capacity of closed cell foams. Especially when dealing with the adhesives, diligence in proper installation techniques is …

Bioluminescence-Based High Precision Bacterial Growth Rate Measurements and Their Potential Application in Quantifying Deleterious Effects of High Mutation Rates
… that a majority of non-neutral mutations are deleterious, there is a long-term cost associated with high mutation rates. This thesis explores the idea that one form of the long-term cost involves the fixation of deleterious mutations when rare beneficial mutations sweep through large asexual …

Outcomes of "off-pump" coronary artery bypass grafting in a developing country : advantages over coronary artery bypass grafting on cardiopulmonary bypass
… grafting (OPCAB) was developed to avoid the deleterious effects of CPB. Current literature reveals some peri-operative advantages of OPCAB, with few studies detailing these in Africa. We review our institutional experience with both approaches in higher risk patients to determine …

BEHAVIORAL RESPONSE TO ALCOHOL IN BINGE DRINKERS
… behavior that is associated with a multitude of deleterious effects for the individual. Studies suggest that binge drinkers may be more likely than non-bingers to experience the immediate negative consequences of alcohol consumption. The present series of studies was designed to examine the …

Cardiovascular and Hematological Effects of Hetastarch and Hypertonic Saline Solutions During Experimental Endotoxemia in Horses
… the equine industry. Objective: To determine the effects of the combination of Hypertonic Saline Solution and Hetastarch in endotoxemic horses. Animals: Eighteen horses divided into three groups of six. Procedure: All horses received a total dose of intravenous E. coli endotoxin infused at 50 …

The control of turbulent flows around bluff bodies by means of spanwise sinusoidal profiles
… and structural fatigue. To obviate these deleterious effects passive flow control mechanisms can be incorporated into the design of bluff bodies. However, to ensure the designs are effective and safe it is essential to understand and anticipate the behavior of the turbulent flows around …

Investigation of the antioxidant activity of phenolic compounds in cell culture systems
… at low concentrations can prevent or reduce the deleterious effects caused by reactive oxygen species (ROS) induced by UVA exposure of the skin. This study focuses on developing methods required to measure the effects of these synthesized compounds in ultraviolet radiation-exposed cultured skin …

Signalling pathways involved in TNFα-induced cytoprotection : role of reactive oxygen species
… cytokine which has both beneficial and deleterious effects. It has previously been shown in our laboratory that TNFa can mimic ischemic preconditioning (IPC). However, the signalling pathways involved in this protection remain incompletely understood. One potential protective pathway …

Black women as monuments in Nella Larsen's Quicksand
… of the process of monumentalization and its deleterious effects on women, who, because they resemble such monuments, are subject to this process. As men construct physical monuments on the landscape in order to bolster their own masculine-centered power structures and ideologies, so do they …

Computational studies of the self-cleavage mechanism in the glmS ribozyme
… cofactor GlcN6P, as well as the beneficial and deleterious effects of metal ions. Computational approaches including classical molecular dynamics (MD), quantum mechanical/molecular mechanical (QM/MM) calculations, and free energy simulations were employed to study the cleavage mechanisms and …

An Investigation of Contact Electrification and Triboelectric Charging in Insulating Materials
… how charge can be transferred. Due to the often deleterious effects of triboelectricity, establishing a fundamental understanding is desired. In this research, we investigated two aspects of triboelectric charging of insulating materials: 1) the influence of material strain, and 2) the influence …

Investigation of different blood pressure regulating systems in kininogen-deficient BNK rats
… according to Langendorff technique. Acute effects of 30min global ischaemia with or without previous ischaemic preconditioning (IPC) were investigated. Myocardial damage was judged by the creatine kinase activity in the coronary effluent measured with a specific kit. BNK rats are …

Controlling harmonic distortion in power electronics using active power filters
… is being drawn. Harmonic distortion can have deleterious effects on the power system, degrading power quality, system performance, and efficiency. Active harmonic filters have gained attention due to the decreasing price and improved availability of power electronics.This thesis discusses some …

Morphological and Hematological Responses to Hypoxia During Development in the Japanese quail, Coturnix coturnix
… 15, and hatch. Hypoxia seemed to have the most deleterious effects on eggs in continuous hypoxia. Collectively, data indicate critical developmental windows for hypoxia susceptibility, especially during mid-embryonic development.

Effects of Exposure to Parental Divorce on the Sibling Relationship in Emerging Adults
Despite divorce's deleterious effects on child siblings and the importance of sibling support across the lifespan, little is known about how parental divorce affects sibling relationships in emerging adulthood. An Internet study investigated how emerging adults' sibling relationships are impacted …

The effects of early developmental stress and exercise intervention on neurodegeneration in a rat model of Parkinson's disease
… stress has been shown to produce numerous deleterious effects, e.g. the later development of affective disorders, and this has been related to chronic enhanced hypothalamic-pituitary-adrenal axis activity. Animal studies have shown that maternally separated rats exhibit increased anxiety- …

Micellar properties of spermicidal and microbicidal quaternary ammonium surfactants
… containing long hydrocarbon-chains can cause deleterious effects when administered to many types of microorganisms. Some compounds have potent activity against spermatozoa and the HIV virus. Consequently, quaternary ammonium lipids are key components in spermicidal and antiseptic formulations. …
