INTRODUCTION: Worldwide, 10-15 % couples are infertile, and 50 % of the couples seeking assisted reproductive techniques do so because of defective sperm quality. The semen quality can be directly linked to oxidative stress (OS). Due to high metabolic rates and weak anti-oxidant systems, sperm cells are unable to defend against OS produced exogenously and endogenously. Vitamin C and/or vitamin E are ...

Breast cancer is the leading cause in cancer deaths among woman worldwide, and one in ten women will experience the disease during their lifetime. Breast cancer accounted for 23% of the total new cancer incidences and 14% of the total cancer deaths in Norway in 2008. One way to potentially improve long-term cancer survival statistics is earlier detection. That includes the discovery and characterization ...

Background: Clinical studies have reported overexpression of PDE5 and elevation of intracellular cyclic GMP in various types of cancer cells. ABCC5 transports intracellular cGMP out of the cells with high affinity, while PDE5 inhibitors prevent high affinity cGMP efflux by inhibiting ABCC5. Increasing intracellular cGMP levels through inhibition of PDE5 and PDE5 export activity is hypothesized ...

Chronic wounds are often colonized with biofilm-producing bacteria, such as Staphylococcus epidermidis, and these wounds often have high degree of complexity and are often challenging to treat. There is a high resistance to the traditional antimicrobial treatments and that is why these infections sometimes are persistent. Photodynamic therapy (PDT) is proposed as a potential solution to the problems ...

Due to inappropriate or excessive use of antibiotics, multi resistance has become a global problem which threatens the public health. Photodynamic therapy has emerged as a promising and important approach in many fields of drug therapy. In recent years, many studies on photodynamic therapy for infections have shown promising results. One of the advantages of using PDT in treatment of infections is ...

Abstract Background There is a need for a common way of documenting and planning pharmaceutical care within the electronic prescribing system used at Ayr hospital. Aims and objectives Conduct a contents analysis of care issues in a formal survey of the care plans in order to categorise the issues, and propose a starting point for an electronic care plan template. Methods Documentation ...

Background Pharmaceutical care as a health care service has already made its mark and been shown to make an important contribution to the health care system. However, there is still a demand from the NHS among others, that pharmacist to a greater extent must document their provision of pharmaceutical care. Tested out in this project, is the application of a Care Issue Categorisation System. ...

Vitamin D is vital for calcium homeostasis and skeletal health, has immunomodulatory effects and is involved in the regulation of differentiation and proliferation of many different cell types. Adipose tissue is an important metabolic organ and a major organ for vitamin D storage. Though, the role of vitamin D and its function in adipose tissue is not fully explored. This thesis applies a solvent ...

In this study, gel phase (DPPC) and liquid phase (soy PC) neutral liposomes were coated with hydrophobically modified hydroxyethyl cellulose (HM-HEC). The chain lengths of the hydrophobic moieties of HM-HEC were C8 and C16. The influence of the hydrophobic chain length of the polymer coating on the release of a fluorescence marker was studied at both 35 °C and 4 °C. I addition the size, zeta ...

The continuous increase in resistance development towards antimicrobial agents is a well-known problem, however, insecurities exist about how frequently the emergence of resistance in microbes, at the same time, leads to an increased sensitivity to other antimicrobial agents. This phenomenon is called “collateral sensitivity”. We evolved resistance in clinical E. coli strains towards three antimicrobial ...
