The unicellular alga Chlamydomonas reinhardtii is surrounded by a cell wall composed entirely of hydroxyproline-rich glycoproteins (HRGPs). When the walls of vegetative cells are removed with the enzyme gamete autolysin (g-lysin), they regenerate a matrix within 3-4 hr. In vitro translation of mRNAs isolated from g-lysin-treated cells showed significant increases and decreases in abundance of s...

Paradoxical growth (PG) has been described for echinocandins and is characterized by cell growth at drug concentrations above the MIC. In this study, two isolates each of Candida albicans, C. tropicalis, C. orthopsilosis, and C. parapsilosis, all of which displaying PG in response to caspofungin, were subjected to MIC, minimal fungicidal concentration (MFC), and time-kill curve assays to evalua...

Initial contact between the opportunistic fungal pathogen Candida albicans and host tissue occurs at the cell surface. Biotin derivatives have been used to label the cell-surface proteins of yeasts, with labelled proteins subsequently detected by avidin-reporter conjugates. Previous work has indicated that avidin can bind to C. albicans proteins in the absence of biotin, suggesting a possible h...

Ryanodine receptor channels regulate contraction of striated muscle by gating the release of calcium ions from the sarcoplasmic reticulum. Ryanodine receptors are expressed in excitable and non-excitable cells of numerous species, including the nematode C. elegans. Unlike vertebrates, which have at least three ryanodine receptor genes, C. elegans has a single gene encoded by the unc-68 locus. W...

A new species of Cataractispora, C. receptaculorum, is described from freshwater habitats. This species is characterized by triseptate verruculose ascospores and polar appendages that unfurl in water. The ascospores lack polar chambers that enclose the appendages as in C. bipolaris and C. viscosa. An ultrastructural study of this species revealed that the ascus wall and apical ring of this spec...

Murine models of cardiac disease are becoming an important tool for studying pathophysiological processes. Development of methods to accurately assess ventricular function are therefore important. The purpose of this study was to evaluate the feasibility of echocardiographic assessment of segmental wall motion abnormalities in a murine model of myocardial infarction. Two-dimensional contrast (C...

traumatic abdominal wall hernias are a type of acquired hernia secondary to blunt trauma caused, by direct trauma from handlebar like objects. this rare hernia is named ‘handlebar hernia'. we report a case of such hernia without any significant intra-abdominal injury. the abdominal wall defect was repaired in layers by jones technique. postoperative course was uneventful. the authors recommend ...

Chlamydiae are obligate generally Gram-negative intracellular parasites with bacterial characteristics, including a cell wall, DNA, and RNA. They have a worldwide distribution in different animal species. Chlamydia felis (C. felis) is an important agent with zoonotic susceptibility often isolated from cats with chronic conjunctivitis. The aim of the present survey aimed ...
