There has been much debate regarding levonorgestrel emergency contraception's (LNG-EC's) method of action since 1999 when the Food and Drug Administration first approved its use. Proponents of LNG-EC have argued that they have moral certitude that LNG-EC works via a non-abortifacient mechanism of action, and claim that all the major scientific and medical data consistently support this hypothes...

OBJECTIVE Levonorgestrel-releasing intrauterine system (LNG-IUS) has been shown to be an effective treatment for patients with abnormal uterine bleeding (AUB) in many Western studies. The purpose of study was to examine the effectiveness of LNG-IUS in the treatment of Indian women with AUB. METHODS We conducted a retrospective observational study of 70 women diagnosed with AUB and treated wit...

Liquefied natural gas (LNG) projects are regulated by host countries, but policy and regulation should depend on geography and meteorology. Without considering the role of geography and meteorology, sub-optimal design choices can result, leading to energy conversion efficiency and capital investment decisions that are less than ideal. A key step in LNG is regasification, which transforms LNG ba...

BACKGROUND The main objective was to investigate if occurrence of hyperplastic polyps was reduced by use of the levonorgestrel-impregnated intrauterine system (LNG-IUS, Mirena®; Bayer) and if the LNG-IUS was more effective compared to oral medroxyprogesterone acetate (MPA) or observation-only. PATIENTS AND METHODS Patients (N=59) with hyperplastic polyps were given LNG-IUS, 10 mg oral MPA tak...

â liquefied natural gas (lng) is the most economical way of transporting natural gas (ng) over long distances. liquefaction of ng by using vapor compression refrigeration system requires high operating and capital cost. due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...

CONTEXT Because menorrhagia is often a reason for seeking medical attention, it is important to consider outcomes and costs associated with alternative treatment modalities. Both the levonorgestrel-releasing intrauterine system (LNG-IUS) and hysterectomy have proven effective for treatment of menorrhagia but there are no long-term comparative studies measuring cost and quality of life. OBJECT...

OBJECTIVE The use of a levonorgestrel intrauterine system (LNG-IUS) is useful in preventing pregnancy and for the treatment of menstrual disturbances. A smooth or symptom-free transition to and through menopause is possible when LNG-IUS is combined with estrogen therapy. Unfortunately the majority of physicians are generally unaware of this usefulness combined hormonal therapy in the pre-, peri...

Considering the large amount of work that goes into the design of LNG processes, there is surprisingly little attention to their subsequent operation. This partly comes from the assumption that optimal design and optimal operation are the same, but this is not generally true. In this paper we study the optimal operation of a relatively simple LNG process, namely the PRICO process.

More rapid increases in the pH value and hardness during electromagnetic heating of a pan of water were observed than when the pan was heated by LNG or LPG. The water quality changed universally in several tap water samples across Japan. This quality change was closely correlated with the rate of temperature increase, irrespective of heating by electromagnetic induction, LNG or LPG.

STUDY QUESTION What is the risk of relapse for women with endometrial hyperplasia treated with levonorgestrel-releasing intrauterine system (LNG-IUS) or oral progestogens? SUMMARY ANSWER Relapse of complex endometrial hyperplasia after initial regression occurs often and it occurs less often in women treated with LNG-IUS than with oral progestogens. WHAT IS KNOWN ALREADY The LNG-IUS and ora...
