Shiatsu is one of only a few complementary therapies featured on the National Childbirth Trust’s DVD given to all pregnant women in the UK. The Shiatsu Society was one of only 13 organisations that sponsored the DVD. We produced a short advertisement which appears on the DVD in between the documentary-style footage about how parents can prepare for the birth of their baby. The film combines inf...
There is now a general trend towards a more baby friendly, family centred approach in the Neonatal Unit. Aspects of that approach-including positive touch and massage- are gaining in popularity. This has caused much debate due to the ambiguity surrounding the implementation and validity of the interventions. Here the impact of these complementary practices (not to be confused with complementary...
Background and Aim: The conventional procedure for removal of porcelain laminate veneers (PLVs) is time-consuming and inconvenient. The purpose of this study was to evaluate the efficacy of Er:YAG laser for debonding of PLVs. Materials and Methods: Forty-eight intact extracted human maxillary anterior teeth received discoid PLVs (24 feldspathic and 24 e-max ceramic). The PLVs had 0.7 mm thickn...
Laser bending is an advanced process in sheet metal forming in which a laser heat source is used to shape the metal sheet. In this paper, temperature distribution in a mild steel sheet metal is investigated numerically and experimentally. Laser heat source is applied through curved paths in square sheet metal parts. Finite element (FE) simulation is performed with the ABAQUS/CAE standard softwa...
Established ablative therapies for the treatment of primary and secondary liver tumours, including percutaneous ethanol injection, cryotherapy, and radiofrequency ablation, are discussed. Newer techniques such as magnetic resonance imaging guided laser interstitial thermal therapy of liver tumours has produced a median survival rate of 40.8 months after treatment. The merits of this newly emerg...
Background Recently, the clinical use of low power lasers has increased, and it is said that wound healing is accelerated by their irradiation. The aim of this study was evaluation of the effect of platelet-rich plasma on proliferation and differentiation of human dental pulp stem cells with or without Ga-Al-As laser. Methods: In this experimental study, human lower third molar dental pulp c...
هدف: این مطالعه به منظور بررسی میزان اثربخشی fractional co2 laser در جوان سازی پوست انجام شده است. روش مطالعه: این مطالعه به صورت یک clinical case series انجام شده است و حجم نمونه مورد بررسی شامل 59 خانم بود که بطور متوالی از بین بیماران مراجعه کننده به کلینیک های پوست و لیزر در سطح شهر تهران در سال 1388 انتخاب شدند. یافته ها: درصد بهبودی در نخستین فالوآپ به طور میانگین 03/85 درصد با انحراف م...
Diabetic macular edema is a main reason for visual loss in diabetic patients. Until recent years, macular laser photocoagulation was the only available therapy. The awareness that inflammation is an important factor in the pathogenetic process of DME gave reason for intravitreal treatment with corticosteroids. The introduction of anti-VEGF drugs brought a revolutionary change in the treatment o...
Primary tracheal tumors are rare neoplasms which often present with indolent and nonspecific symptoms. Despite a tendency for late presentation, more than half of patients with benign and malignant neoplasms will be candidates for curative resection upon diagnosis. This review describes the diagnostic and staging evaluation of tracheal neoplasms. Curative surgical procedures including laryngotr...
Objective: The aim of this study was to evaluate and compare the effect of dental surface treatment with Er:YAG , Nd:YAG ,CO2 lasers and sodium ascorbate to recently laser bleached enamel by scanning electron microscope (SEM). Methods: 15caries-free extracted human third molars were selected for this study. The samples were bleached by Heydent JW power activated by diode laser 810 nm. After 7 d...
