Investigations into the Melitaea ornata species complex in the Levant: M. telona and the newly erected species Melitaea klili Benyamini, 2021 (Lepidoptera: Nymphalidae).

Melitaea klili Benyamini, 2021 was recently described from Israel as a species closely related to M. telona Fruhstorfer, 1908, but different in phenology, ecological preferences and with an allopatric distribution. Here, based on comparative examinations of mitochondrial DNA-barcodes, male genitalia and larval behaviour under laboratory conditions, we synonymize M.

Algorithms to guide ambulance clinicians in the management of emergencies in patients with implanted rotary left ventricular assist devices.

Advances in left ventricular assist device (LVAD) therapy have resulted in increasing numbers of adult LVAD recipients in the community. However, device failure, stroke, bleeding, LVAD thrombosis and systemic infection can be life-threatening emergencies. Currently, four LVAD systems are implanted in six UK transplant centres, each of which provides device-specific information to local emergency services.

Utstein-style audit of Protocol C: a non-standard resuscitation protocol for healthcare professionals.

Introduction: International guidelines for basic life support and defibrillation are identical for lay people and healthcare professionals. In 2002, a small meeting hosted by the Resuscitation Council (UK) debated recent advances in resuscitation science, along with the possibility of more demanding procedures for treating out of hospital cardiac arrest (OHCA) that could take advantage of the expertise available with professional use. The resulting algorithm known as Protocol C could not be tested in a randomized trial for reasons relating to consent, but was introduced by one ambulance service as an observational study.

Basics in advanced life support: a role for download audit and metronomes.

An intention in 2003 to undertake a multicentre trial in the United Kingdom of compressions before and after defibrillation could not be realized because of concerns at the time in relation to informed consent. Instead, the new protocol was introduced in one ambulance service, ahead of the 2005 Guidelines, with greater emphasis on compressions. The results were monitored by analysis of electronic ECG downloads.

A double-blind randomised comparison of ropivacaine 0.5%, bupivacaine 0.375% - lidocaine 1% and ropivacaine 0.5% - lidocaine 1% mixtures for cataract surgery.

This study evaluated the efficacy and side-effects of plain ropivacaine compared with ropivacaine-lidocaine and bupivacaine-lidocaine mixtures for peribulbar blocks in cataract surgery. Ninety patients were randomly allocated to three groups and received peribulbar blockade using one of the three solutions. Speed of onset and quality of blockade were assessed using akinesia, surgical satisfaction and patient satisfaction.

Citrobacter diversus ventriculitis and brain abscesses in an adult.

A case of Citrobacter diversus brain abscesses following urinary infection in an adult is described. The patient was treated with surgical drainage, netilmicin and cefotaxime. Citrobacter species CNS infection is discussed.

Antibody response and clinical reactions in children given measles vaccine with immunoglobulin.

Antibody responses and clinical reactions to three measles vaccines (Attenuvax, Mevilin, and Rimevax) injected into the opposite arm to immunoglobulin were assessed in 45 children with brain disorders making them susceptible to fits if given measles vaccine alone. In this small study no unacceptable reactions occurred and in only three cases was the antibody response minimal or absent. More children in this special category should be considered for vaccination against measles in this way.

Role of an immunisation advisory clinic.

An immunisation advisory clinic was set up in Redbridge in 1984 to try to allay the anxieties of parents and doctors about vaccination against whooping cough and measles. The parents agreed to vaccination for 54 out of 67 children against whooping cough and 54 out of 57 against measles. Most of the 117 children who were referred to the clinic probably would not have been vaccinated, although only two had valid contraindications.

Genomic clones of Aspergillus nidulans containing alcA, the structural gene for alcohol dehydrogenase and alcR, a regulatory gene for ethanol metabolism.

Our aim was to obtain from Aspergillus nidulans a genomic bank and then clone a region we expected from earlier genetic mapping to contain two closely linked genes, alcA, the structural gene for alcohol dehydrogenase (ADH) and alcR, a positive trans-acting regulatory gene for ethanol metabolism. The expression of alcA is repressed by carbon catabolites. A genomic restriction fragment characteristic of the alcA-alcR region was identified, cloned in pBR322, and used to select from a genomic bank in lambda EMBL3A three overlapping clones covering 24 kb of DNA.

Purification and preliminary characterization of alcohol dehydrogenase from Aspergillus nidulans.

Aspergillus alcohol dehydrogenase is produced in response to growth in the presence of a wide variety of inducers, of which the most effective are short-chain alcohols and ketones, e.g. butan-2-one and propan-2-ol.

A polyamine-sensitive mutant of Aspergillus nidulans.

A mutation designated spsA1 has been induced in the putrescine (puA2) auxotroph of Aspergillus nidulans which enables this mutant to grow on low concentrations of spermidine in place of putrescine. In addition, the spsA1 mutant, irrespective of putrescine requirement, is abnormally sensitive to high concentrations of spermidine, spermine or the polyamine analogue methylglyoxal bis(guanylhydrazone). When spsA1 strains are grown on medium containing spermidine, uptake of the polyamine continues at a high level for a longer period than in the wild-type and leads to a doubled intracellular spermidine pool.

Urea and thiourea transport in Aspergillus nidulans.

Wild-type Aspergillus nidulans has an active transport system specific for urea which concentrates urea at least 50-fold relative to the extracellular concentration. It is substrate concentration dependent, with an apparent Km of 3 x 10-(5) M for urea. Competition studies and the properties of mutants indicate that thiourea is taken up by the same system as urea.
