An important question in cell biology is whether cells are able to measure size, either whole cell size or organelle size. Perhaps cells have an internal chemical representation of size that can be used to precisely regulate growth, or perhaps size is just an accident that emerges due to constraint of nutrients. The eukaryotic flagellum is an ideal model for studying size sensing and control be...
The detection of IgM antibodies for Schistosoma mansoni using gut-associated antigens (IgM-IFT) was compared to the parasitological Kato-Katz method for study of the transmission of schistosomiasis in an urban area in Campinas. About 400 schoolchildren whose ages ranged from 6 to 18 years, were observed for a period of two years. Blood samples on filter paper and fecal samples were collected, a...
The present study examined the long-term treatment outcomes of family-centered program Intensive Family Treatment (IFT) for families with multiple problems. We also tested hypothesis that parental empowerment at end IFT constitutes a buffer between negative influences stress on their children’s behavioral problems afterwards. included 275 Information about and child was gathered start follow-up...
Information flow tracking (IFT) is a fundamental computer security technique used to understand how information moves through computing system. Hardware IFT techniques specifically target vulnerabilities related the design, verification, testing, manufacturing, and deployment of hardware circuits. can detect unintentional design flaws, malicious circuit modifications, timing side channels, acce...
Intraflagellar transport (IFT) is required for construction of most cilia and flagella. Here, we used electron microscopy, immunofluorescence and live video microscopy to show that IFT is absent or arrested in the mature flagellum of Trypanosoma brucei upon RNA interference (RNAi)-mediated knockdown of IFT88 and IFT140, respectively. Flagella assembled prior to RNAi did not shorten, showing tha...

Sensory organelle cilia have critical roles in mammalian embryonic development and tissue homeostasis. Intraflagellar transport (IFT) machinery is required for the assembly and maintenance of cilia. Yet, how this large complex passes through the size-dependent barrier at the ciliary base remains enigmatic. Here we report that FBF1, a highly conserved transition fibre protein, is required for th...
Bidirectional (anterograde and retrograde) motor-based intraflagellar transport (IFT) governs cargo transport and delivery processes that are essential for primary cilia growth and maintenance and for hedgehog signaling functions. The IFT dynein-2 motor complex that regulates ciliary retrograde protein transport contains a heavy chain dynein ATPase/motor subunit, DYNC2H1, along with other less ...
The assembly and function of cilia on Caenorhabditis elegans neurons depends on the action of two kinesin-2 motors, heterotrimeric kinesin-II and homodimeric OSM-3-kinesin, which cooperate to move the same intraflagellar transport (IFT) particles along microtubule (MT) doublets. Using competitive in vitro MT gliding assays, we show that purified kinesin-II and OSM-3 cooperate to generate moveme...
The atypical small G protein Rab-like 5 has been shown to traffic in sensory cilia of Caenorhabditis elegans, where it participates in signalling processes but not in cilia construction. In this report, we demonstrate that RABL5 colocalises with intraflagellar transport (IFT) proteins at the basal body and in the flagellum matrix of the protist Trypanosoma brucei. RABL5 fused to GFP exhibits an...
