The Levonorgestrel intrauterine device (LNG-IUD) is a hormone-containing device licensed for treatment of menorrhagia and contraception. Though complications such as perforation have been reported similar to other non-hormonal intrauterine devices, the diagnosis of such complications is difficult with this device because the LNG-IUD has a different ultrasound appearance compared to copper devic...

Barriers to hormonal emergency contraceptive (EC) access in Canada and the United States led professional and lay groups to lobby for levonorgestrel (LNG) (PLAN B, Barr Pharmaceuticals, Pomona, New York) to be made available over-the-counter. In December 2000, British Columbia, Canada, granted EC prescriptive authority to pharmacists, followed by Quebec in December 2001 and Saskatchewan in Sept...

AIM To investigate if a levonorgestrel-impregnated intrauterine system (LNG-IUS) was more efficient compared to oral progestin in the clearance of the paired box 2 gene (PAX2) - and phosphatase and tensin homolog (PTEN)-null endometrial glands and assess the significance of PAX2- and PTEN-null glands as markers for therapy response in endometrial hyperplasia. PATIENTS AND METHODS Immunohistoc...

8 A comprehensive model for predicting the dynamics of spills from LNG and oil product tankers 9 is constructed from fluid mechanics principles and empirical properties of oil and LNG spills on 10 water. The analysis utilizes the significant tanker hold and discharge flow area dimensions to specify 11 the cargo liquid outflow history and the ensuing pool characteristics, including the establish...

P lanta de Regasificacion de Sagunto, S.A (Saggas) is constructing a new LNG receiving facility in Sagunto, 50 km north of Valencia (Spain), with a capacity of 3 million tpy of LNG, to be supplied from Egypt through a project initially promoted by Union Fenosa. Saggas is owned by three major electric companies in Spain: Union Fenosa (50%), Iberdrola (30%) and Endesa (20%). Saggas will be in cha...

During transportation, there will be vaporization of LNG producing boil-off gas (BOG) and its re-liquefaction is required considering that large volume of BOG to be vented out. A cryogenic refrigeration cycle is utilized in order to re-liquefy the BOG and returns it to the cargo tank. Kapitza and claude are the usually used LNG re-liquefaction cycles. The developments in the processes adopted f...

STUDY QUESTION What is the bleeding pattern during second consecutive levonorgestrel-releasing intrauterine system (LNG-IUS) use? SUMMARY ANSWER Consecutive use of LNG-IUS is associated with a predictable bleeding pattern, characterized by the absence of the initial period of irregular bleeding seen after interval insertion of an LNG-IUS and a non-bleeding pattern in the vast majority of wome...

STUDY QUESTION Is the pain associated with levonorgestrel-releasing intrauterine system (LNG-IUS) insertion reduced by intracervical anesthesia in women without previous vaginal birth? SUMMARY ANSWER Intracervical anesthesia was not associated with reduced pain in women without previous vaginal birth. WHAT IS KNOWN ALREADY The pain associated with the insertion of intrauterine contraceptive...

BACKGROUND The effects of oral contraceptives (OCs) on mental health are not clear, and no study has been focused on the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) on mental health. The aim of this study was to analyse the association between the use of OCs and the LNG-IUS and psychological well-being and psychopathology. METHODS The associations between the current...

Nowadays, most merchant vessels use Heavy Fuel Oils (HFOs) for the ship propulsion. These fuels are cost effective but they produce significant amounts of noxious emissions. To comply with IMO & MARPOL environmental regulations, Liquefied Natural Gas (LNG) is becoming an interesting option for the merchant ships. The purpose and scope of this paper is to describe the fact...
