The unicellular green alga Chlamydomonas reinhardtii is a widely used model organism for studies of oxygenic photosynthesis in eukaryotes. Here we describe the development of a resource for functional genomics of photosynthesis using insertional mutagenesis of the Chlamydomonas nuclear genome. Chlamydomonas cells were transformed with either of two plasmids conferring zeocin resistance, and ins...

INTRODUCTION To preserve residual hearing the atraumaticity of the cochlea electrode insertion has become a focus of cochlear implant research. In addition to other factors, the speed of insertion is thought to be a contributing factor in the concept of atraumatic implantation. The aim of our study was to observe intracochlear fluid pressure changes due to different insertional speeds of an imp...

BACKGROUND Anterior nucleus (AN) deep brain stimulation (DBS) is a palliative treatment for medically refractory epilepsy. The long-term efficacy and the optimal target localization for AN DBS are not well understood. OBJECTIVE To analyze the long-term efficacy of AN DBS and its predictors. METHODS We performed a retrospective review of 16 patients who underwent AN DBS. We selected only pat...

background: acute lymphoblastic leukemia (all) is the most common subtype of childhood cancer. chromosomal ab­normality, specially the replacement of chromosomal material is one of the main reasons in generating leukemia, wherein the kind of translocation play a key role in managing the remedy. the goal of the present study was to develop a reliable, rapid, and cost effective method to detect t...

The pleckstrin homology (PH) domains of a number of proteins have been found to interact in vitro with inositol phospholipids; recent experiments show that these interactions may be important in directing protein translocation to specific parts of the cell following stimulus-induced lipid breakdown or synthesis.

uniparental disomy (upd) is a situation in which both members of a chromosome pair are inherited from one parent. this study has been conducted on a family with a five year-old healthy girl and a mentally retarded boy. the parents were first cousins and they both had robertsonian translocation between their long arm of chromosome 13 and 14 [45, xy t (13q14q)]. their affected son had a similar k...

a large number of simple or complex translocation involving the cml and aml chromosomal abnormalities has been described. this study was aimed to investigate the complex chromosome aberrations in the series of myeloid malignancies including cml and aml. the present report deals analyzed 187 consecutive with cml and aml patients, using methotrexate  cell synchronization and  un-stimulated cultur...

background: carriers of translocations may have an increased risk of an unbalanced progeny due to imbalances and delays in meiosis. case: a 24-year-old pregnant iranian female was referred to the genetic department of yazd clinical and research centre for infertility because of her pregnancy history. she had three previous pregnancies, two of which ended in abortion. the one live born infant wa...
