Abstract Serial homology, i.e., homology between repetitive structures in the same individual organism, is a debated concept evolutionary developmental biology. The central question interpretation of “sameness” context body. This essay provides synthetic analysis main issues involved debate, connecting conceptual problems with current experimental research. It argued that serial not all-or-noth...

Antibiotic-resistant strains of Escherichia coli and, to a lesser extent, Klebsiella-Enterobacter were common in serial samples of the normal intestinal flora of healthy young adults in Thailand, and the resistance often was to multiple drugs and was transferable. Antibiotic administration promoted dominance of the flora by drug-resistant organisms regardless of the drug regimen and the predrug...

Twenty-five serial passages of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus and 50 passages of methicillin-resistant Staphylococcus aureus resulted in no significant increase in NVC-422 MICs, while ciprofloxacin MICs increased 256-fold for E. coli and 32-fold for P. aeruginosa and S. aureus. Mupirocin, fusidic acid, and retapamulin MICs for MRSA increased 64-, 256-, and 1...

Here, we describe a case of an HIV-infected patient with right lower limb oedema that appeared after initiation of tenofovir and emtricitabine treatment. The patient was fully investigated by serial heart and vessel echo-Doppler examination. Oedema of the lower limb was attributed to a transient drug-induced fivefold increase in peripheral artery flow, which was induced by a reduction in periph...

The design of an interface unit is described, in which RS232 serial data is converted to latched parallel data on 22 independent lines. The data direction of each line is programmable through the serial port. Two picocontrollers are employed in a parallel processing mode to give the required number of I/O pins, and data on the shared serial line is coded to separate data streams to the individu...

The leading fungal pathogens causing systemic infections in humans are Candida spp., Aspergillus fumigatus , and Cryptococcus neoformans . major class of antifungals used to treat such the triazoles, which target cytochrome P450 lanosterol 14-α-demethylase, encoded by ERG11 (yeasts)/ cyp51A (molds) genes, catalyzing a key step ergosterol biosynthetic pathway. Triazole resistance clinical fungi ...
