Abdomen: Surgical Anatomy and General Consideration in Emergency Settings
The knowledge of anatomy and the basics of the clinical framework are essential to approach a surgical patient in an emergency. This chapter discusses the basics of abdominal wall anatomy and the first steps for a young abdominal surgeon
Sudden death due to Waterhouse-Friderichsen syndrome and purulent leptomeningitis caused by acinetobacter calcoaceticus (Mima polymorpha)
A case of Waterhouse-Friderichsen syndrome presenting with purulent leptomeningitis causing sudden death is described. The causative agent, Acinetobacter calcoaceticus (Mima polymorpha), was determined by post-mortem microbiological examination. © 1977 Springer-Verlag Berlin • Heidelberg
Rapid detection of Paenibacillus larvae from honey and hive samples with a novel nested PCR protocol.
Superoxide dismutase, catalase and cell dimorphism in Candida albicans cells exposed to methanol and different temperatures.
The combined effects of methanol and different temperatures on Candida albicans were studied. Growth curve, cell morphology, superoxide dismutase (SOD) and catalase activity levels have been determined. Cell growth in each medium was comparable to 28 degrees C and 37 degrees C. The growth rate was not affected by methanol, in the presence of glucose, while it was much lower in the absence of sugar. Cell dimorphism appeared after thermic stress and it was also dependent on the medium composition. In all media, both SOD and catalase levels were much higher at 37 degrees C. The presence of methanol per se did not affect the enzymatic levels, while the absence of glucose gave higher SOD levels
BIOCHEMICAL AND MORPHOLOGICAL-CHANGES IN ESCHERICHIA-COLI IRRADIATED BY COHERENT AND NONCOHERENT 632.8 NM LIGHT
Irradiation of Escherichia coli cells with either coherent or non-coherent 632.8 nm light (4 J cm-2) causes a transient acceleration of cell proliferation, which is maximal about 60 min after the end of the phototreatment. The stimulatory effect is dose dependent and is especially evident in the case of defective E. coli strains which are in the logarithmic phase of growth, while it becomes less important when cells are exposed to non-coherent 600-700 nm light. Stimulated cells exhibit biochemical and morphological changes, such as an intensified synthesis of cytoplasmic membrane proteins, increased cell volume and ribosomal content, which are suggestive of an enhanced cell metabolism
Hematoporphyrin-sensitized photoinactivation of yeast cells
We investigated the hemaporphyrin-binding and photosensitization of Candida albicans cells. Like bacterial cells, the cytoplasmic membrane is the earliest photodamaged site, but probably also the nuclear membrane is involved in photoprocess and photoinactivation
Non thermal pasteurization of foodstuff by dense gases: experimental data, sensorial analysis and inactivation mechanism
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
