Members of the widespread rhomboid family of intramembrane proteases cleave transmembrane domain (TMD) proteins to regulate processes as diverse as EGF receptor signaling, mitochondrial dynamics, and invasion by apicomplexan parasites. However, lack of information about their substrates means that the biological role of most rhomboids remains obscure. Knowledge of how rhomboids recognize their ...
Background: The use of random flaps is one of the most common methods of reconstructive surgery because they are easy to use and quick to do. However, the absence of axial vessels especially in the distal areas can cause ischemia and loss of total or part of the flap. Different methods and systemic and topical medications have been recommended to prevent ischemia in random flaps. The aim of thi...
introduction: providing the material for penile reconstruction after release of chordee associated with hypospadias is challenging. we have used the preputial vascularized island flap for this purpose. we report the results of this prospective study. materials and methods: one hundred and twelve boys ranging from 13 months to 12 years of age were enrolled in this study. the location of meatus r...
Rothia mucilaginosa is a part of the normal oral microflora, which has been recognized as an endodontic pathogen and also emerging opportunistic in immune compromised hosts. In this study, we identified rhomboid protease R. candidate virulence factor. A database search two genes on genome with open reading frames 828 bp 822 bp, respectively. The are separated by 57 suggesting that they constitu...
Despite all modern surgical techniques, skin flap that is considered as the main method in most reconstructive surgeries puts the skin tissue at danger of necrosis and apoptosis derived from ischemia. Therefore, finding a treatment for decreasing the apoptosis derived from flap ischemia will be useful in clinic. In present study, we evaluated the effect of azelaic acid 20% and finasteride on ex...

Approximately 40% of the mitochondria in the sphincter muscle of the crayfish vas deferens have prismatic-type cristae. In cross section, the angular cristae have either triangular or rhomboid profiles which are surrounded by a hexagonal array of electron-dense dots. In longitudinal section, these mitochondria exhibit both thick and thin parallel lines, which represent cristae and filaments, r...
Rhomboids, evolutionarily conserved integral membrane proteases, participate in crucial signaling pathways. Presenilin-associated rhomboid-like (PARL) is an inner mitochondrial membrane rhomboid of unknown function, whose yeast ortholog is involved in mitochondrial fusion. Parl-/- mice display normal intrauterine development but from the fourth postnatal week undergo progressive multisystemic a...
Apicomplexan parasites secrete transmembrane (TM) adhesive proteins as part of the process leading to host cell attachment and invasion. These microneme proteins are cleaved in their TM domains by an unidentified protease termed microneme protein protease 1 (MPP1). The cleavage site sequence (IA downward arrowGG), mapped in the Toxoplasma gondii microneme proteins TgMIC2 and TgMIC6, is conserve...
Introduction: Reconstruction of the oral cavity witha flap design containing the buccal mucosa and buccinator muscle but excluding the facial artery and vein is the topic of these case reports. Case Reports: This article uses random pattern vertically oriented partial thickness buccinator myomucosal flap for intraoral reconstruction in two cases. The first was for lining the mandibular anterior...
