in endodontics, treatment of an open apex tooth with necrotic pulp is a problem. it seems that with promotion of remnants of hertwig’s epithelial sheath or rest of malassez accompany with a good irrigation of root canal we can expect root formation.
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
The expression pattern of the immunoglobulin DM-GRASP/BEN gene was studied in the mouse embryo using in situ hybridization. DM-GRASP/BEN is expressed in the spinal cord in a subset of motoneurons expressing Islet-1, and non homogeneously in the dorsal root ganglia (DRG). In contrast, it's expression is homogeneous in the vestibulo-cochlear and trigemminal ganglia. DM-GRASP/BEN is also expressed...
Introduction: Basal cell carcinoma (BCC) is the most common cutaneous malignancy that humans acquire in the course of a lifetime (1). It is a malignant skin tumor arising from basal cells of the surface epidermis or external root sheath of the hair follicle. Case Report: 80 year old female farmer by occupation presented with chief complaints of blackish patch over the left lateral side of nose ...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
single rooted primary mandibular first molar is a rare developmental anomaly. literatures reveal that failure of invagination of hertwig's epithelial root sheath leads to this unusual root form. thorough knowledge of root canal morphology and anatomical variations of primary teeth can help a pediatric dentist in successful root canal treatment. hereby, we describe two cases of primary mandibula...
The hair follicle consists of several distinctive epidermal cell layers. The hair root, which undergoes keratinization, is surrounded by two sheaths: the inner root sheath (IRS) and the outer root sheath (ORS). The ORS is continuous with the basal layer of the epidermis. Its cells do not keratinize in situ, unlike IRS. We have previously demonstrated that keratinization of the ORS was prevented...
We show that removing the Shh signal tranducer Smoothened from skin epithelium secondarily results in excess Shh levels in the mesenchyme. Moreover, the phenotypes we observe reflect decreased epithelial Shh signaling, yet increased mesenchymal Shh signaling. For example, the latter contributes to exuberant hair follicle (HF) induction, while the former depletes the resulting follicular stem ce...
this thesis examines the significances and implications of inflicted physical pain in waiting for the barbarians (1980) by john maxwell coetzee (1940 - ). the researcher tries to show how body becomes a site for exercising violence. in this way, the government’s representatives turn bodies of the barbarians into blank pages through torturing in order to create the truth of the empire. in this p...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
