  1. 1. Constraints on up-regulation of drug efflux in the evolution of ciprofloxacin resistance

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa Praski Alzrigat; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ciprofloxacin; antibiotic resistance; drug efflux; bacterial fitness; marR; acrR; marA; experimental evolution; Mikrobiologi; Microbiology;

    Abstract : The crucial role of antibiotics in modern medicine, in curing infections and enabling advanced medical procedures, is being threatened by the increasing frequency of resistant bacteria. Better understanding of the forces selecting resistance mutations could help develop strategies to optimize the use of antibiotics and slow the spread of resistance. READ MORE

  2. 2. An Associative Memory Trace in the Cerebellar Cortex

    University dissertation from Department of Experimental Medical Science, Lund Univeristy

    Author : Dan-Anders Jirenhed; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; neuropsychology; Classical Conditioning; Cerebellum; Purkinje cell; Physiology; Fysiologi; Neurology;

    Abstract : Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the response.

  3. 3. Cerebellar Control of Classical Conditioning

    University dissertation from Department of Physiological Sciences, Lund University

    Author : Magnus Ivarsson; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Associative module; Bilateral; Orbicularis oculi muscle; Inferior olive; Purkinje cell; Eyeblink; Conditioned response; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology;

    Abstract : It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles.
