BACKGROUND Syphilitic chorioretinitis can produce severe vision loss. However, the clinical manifestations of syphilitic chorioretinitis are still unclear, particularly during different stages. Herein, we will present our diagnostic technique for syphilitic chorioretinitis. METHODS This retrospective study recruited 109 cases; we performed a clinical evaluation including case history, serolog...

We present calculations of the localisation length, 2 , for two interacting particles (TIP) in a one-dimensional random potential, presenting its dependence on disorder, interaction strength U and system size. 2 (U) is computed by a decimation method from the decay of the Green function along the diagonal of nite samples. Innnite sample size estimates 2 (U) are obtained by nite-size scaling. Fo...

Class III myosins are motor proteins that contain an N-terminal kinase domain and a C-terminal actin-binding domain. We show that myosin IIIa, which has been implicated in nonsyndromic progressive hearing loss, is localized at stereocilia tips. Myosin IIIa progressively accumulates during stereocilia maturation in a thimble-like pattern around the stereocilia tip, distinct from the cap-like loc...

Pollen tube elongation depends on the secretion of large amounts of membrane and cell wall materials at the pollen tube tip to sustain rapid growth. A large family of RAS-related small GTPases, Rabs or Ypts, is known to regulate both anterograde and retrograde trafficking of transport vesicles between different endomembrane compartments and the plasma membrane in mammalian and yeast cells. Stud...

We present calculations of the localisation length, λ2, for two interacting particles (TIP) in a one-dimensional random potential, presenting its dependence on disorder, interaction strength U and system size. λ2(U) is computed by a decimation method from the decay of the Green function along the diagonal of finite samples. Infinite sample size estimates ξ2(U) are obtained by finite-size scalin...

In vitro plantlet regeneration has been obtained from 20-25days old seedling shoot tip segments of Cucumis melo (L.). We were examined using various phyto hormones individually and in combination on Murashige and Skoog (MS) semi solid medium supplemented with BAP (1.0-3.0 mg/L) Kn (1.0-3.0 mg/L),IAA (0.5 mg/L)+ BAP (1.0-3.0 mg/L) and IAA (0.5 mg/L)+Kn (1.0-3.0 mg/L) for multiple shoots prolifer...

SPA2 encodes a yeast protein that is one of the first proteins to localize to sites of polarized growth, such as the shmoo tip and the incipient bud. The dynamics and requirements for Spa2p localization in living cells are examined using Spa2p green fluorescent protein fusions. Spa2p localizes to one edge of unbudded cells and subsequently is observable in the bud tip. Finally, during cytokines...

Mechanically gated "transduction" channels in inner ear hair cells are thought to be connected to tip links stretched between adjacent stereocilia. To locate active channels, calcium-green fluorescence in single stereocilia was measured with two-photon laser scanning microscopy. Bundle deflection increased fluorescence in many but not all stereocilia; the increase was blocked by depolarization....

We wanted to examine the cellular locations of four Neurospora crassa proteins that transport calcium. However, the structure and distribution of organelles in live hyphae of N. crassa have not been comprehensively described. Therefore, we made recombinant genes that generate translational fusions of putative organellar marker proteins with green or red fluorescent protein. We observed putative...

Experiments with inside-out patches excised from pancreatic B-cells have yielded evidence that mitochondria are often contained in the cytoplasmic plug protruding into the tip of patch pipette. When intact B-cells were loaded with the fluorescent mitochondrial stain, rhodamine 123, and membrane patches excised from these cells, a green fluorescence could be observed in the lumen at the tip of t...
