Whispering gallery mode resonances in liquid droplets and microspheres have attracted considerable attention due to their potential uses in a range of sensing and technological applications. We describe a whispering gallery mode sensor in which standard optical fibre is used as the whispering gallery mode resonator. The sensor is characterised in terms of the response of the whispering gallery ...

BACKGROUND Cholelithiasis is one of the most prevalent gastrointestinal disorders requiring hospitalization.  While different factors influence gallstone formation in patients, these factors are not the same in different societies or in different geographical locations. AIM To evaluate the epidemiology and risk factors associated with gallstone formation in a large population group, the prese...

Cloned Salmonella DNA, which has been immobilized irreversibly on plastic and agarose solid supports, can form hybrids in both single-layer and "sandwich" hybridization protocols. In single-layer hybridization, 3 micrograms of immobilized DNA bound at least 30 fmol of a specific 800-base DNA sequence (equivalent to 8.5 ng, or the amount of that sequence present in 4 X 10(10) organisms). In a 4-...

Shiga-like toxins (verotoxins) are responsible for the virulence associated with a variety of foodborne bacterial pathogens. Direct detection of toxins requires a specific and sensitive technique. In this study, we describe a mass spectrometry-based method of analyzing the tryptic decapeptides derived from the non-toxic B subunits. A gene encoding a single protein that yields a set of relevant ...

P140K-MGMT and G156A-MGMT genes encode two O-benzylguanine–resistant O-alkylguanine DNA alkyltransferase proteins that confer a high degree of Obenzylguanine and 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) or O-benzylguanine and temozolomide resistance to primary hematopoietic cells. In this study, we directly compared these and three other O-benzylguanine– resistant MGMT genes for their abilit...

Declaration This thesis is a presentation of my original research work. Wherever contributions of others are involved, every effort is made to indicate this clearly, with due reference to the literature, and acknowledgement of collaborative research and discussions. In my capacity as supervisor of the candidate's thesis, I certify that the above statements are true to the best of my knowledge. ...

Accelerator mass spectrometry (AMS) is the analytical technique of choice for the detection of long-lived radionuclides that cannot be practically analysed with decay counting or conventional mass spectrometry. AMS has been used for the analysis of C, Be, Cl and other cosmogenic radionuclides in archaeology, geology and environmental science. In addition, the ultrasensitivity of AMS is being ap...

To determine whether intracerebrally localized iodothyronines produce thyroid hormone-related functional effects, heart rate responses were compared in conscious hypothyroid rats given triiodothyronine (T3) by either the intrathecal or the intravenous route. A significant increase in heart rate occurred within 18 h after 1.5 amol T3/100 g body wt was delivered intrathecally through a cannula pr...
