PURPOSE: Release of the orbicularis retaining ligament (ORL) has been advocated as a technique to address tear trough deformities. This study sought to compare the effectiveness and morbidity of lower blepharoplasty with and without ORL release. METHODS: Retrospective chart review of 53 lower blepharoplasty patients. Twenty-six patients had ORL release and 27 patients did not. Three independent masked experienced cosmetic surgeons reviewed preoperative and postoperative photographs to assess degree of swelling, ecchymosis, change in steatoblepharon and tear trough deformity, and overall aesthetic result...

We developed an in-silico mathematical model of retinal cholesterol (Ch) dynamics (RCD) to quantify the physiological rate of Ch turnover in the rod outer segment (ROS), the lipoprotein transport mechanisms by which Ch enters and leaves the outer retina, and the rates of drusen growth and macrophage-mediated clearance in dry Age-Related Macular Degeneration (AMD). Based on existing experimental data and mechanistic hypotheses, we estimate the Ch turnover rate in the ROS to be 1-6 pg/mm2/min, dependent on the rate of Ch recycling in the outer retina, and find comparable rates for LDL receptor-mediated endocytosis of Ch by the retinal pigment epithelium (RPE), ABCA1-mediated Ch transport from the RPE to outer retina, ABCA1-mediated Ch efflux from the RPE to choroid, and the secretion of 70 nm ApoB-Ch particles from the RPE...

Cancer is one of the most important issues in modern medicine and the most common cause of death after cardiovascular diseases in many countries. Brain cancer is one of the most common causes of cancer death among men and women, ranking third. Chemotherapeutic drugs that aim to prevent uncontrolled proliferation of cells in tissues of the body and induce apoptosis of tumor cells are prominent candidates for development. Since cisplatin has an apoptosisinducing role, it is widely used as an anticancer agent...

MicroRNAs (miRNAs), are a type of small non-coding RNAs, that induce mRNA degradation or repress translation by binding to the 3′-untranslated region (UTR) of its target mRNA. Some specific miRNAs, e.g. miR-93, have been discovered to be involved in pathological procedures by targeting some oncogenes or tumor suppressors in glioma. In the present study, real-time RT-PCR data was indicated the expression pattern and prognostic value of miR-93 in patients with types of Glioma.MiR-93 expression was significantly decreased in tumor tissue compared with normal group brain tissues (P<0...

DNA repair is responsible for maintaining the integrity of the genome. Perturbations in the DNA repair pathways have been identified in several human cancers. Thus, compounds targeting DNA damage response (DDR) hold great promise in cancer therapy. A great deal of effort, in pursuit of new anticancer drugs, has been devoted to understanding the basic mechanisms and functions of the cellular DNA repair machinery. Melatonin, a widely-produced indoleamine in all organisms is associated with a reduced risk of cancer and has multiple regulatory roles on the different aspects of the DDR and DNA repair...

Only a single donor's tissue may save or improve lives of one hundred patients. Unfortunately, low governmental and media support of tissue procurement and transplantation programs is a worldwide problem. Loss of an effective tissue procurement program in many countries like Iran, may lead to loss of many thousands valuable tissues each year. To evaluate the rate of skin donation in Mashhad in comparison to other organs and tissues, we extracted the data related to tissue and organ procurement in Mashhad from 2001...

BACKGROUND: Periodontal diseases refer to inflammation of the gingiva, induction of apoptosis in human gingival fibroblast cells, destruction of the surrounding tissues, and early bone loss resulting in infections due to the pathogenic activity of the microorganisms and the host immune inflammatory responses. Recent investigations have suggested that antimicrobial photodynamic therapy (aPDT) can be an adjunct treatment therapy for periodontal infections. AIM: To prove the lack of side effects of PDT on periodontal tissues, we investigated the expression of BAX and BCL-2 genes that are involved in apoptosis after the PDT on human gingival fibroblast (HGF) cells...

In this paper, consensus problem is considered for second order multi-agent systems with unknown nonlinear dynamics under undirected graphs. A novel distributed control strategy is suggested for leaderless systems based on adaptive fuzzy wavelet networks. Adaptive fuzzy wavelet networks are employed to compensate for the effect of unknown nonlinear dynamics. Moreover, the proposed method is developed for leader following systems and leader following systems with state time delays. Lyapunov functions are applied to prove uniformly ultimately bounded stability of closed loop systems and to obtain adaptive laws...
