A polyclonal antibody (Ab) for the progestin levonorgestrel (LNG) was generated, and immunochemical assays for its detection, clean-up and concentration were developed. A highly specific microplate diagnostic assay for the detection of LNG was developed that used the enzyme linked immunosorbent assay (ELISA) method. The LNG ELISA developed was sensitive and reproducible; it exhibited I(50) and ...

BACKGROUND Glanzmann's Thrombasthenia (GT) is an inherited genetic disorder caused by defects in the platelet membrane glycoproteins IIb/IIIA, and is associated with heavy menstrual bleeding (HMB). HMB is a common complication in female patients, and many adolescent girls with this disease have issues with HMB beginning at menarche. The available treatment modalities including anti-fibrinolytic...

INTRODUCTION The search for an ideal contraceptive device most suited for women of developing countries with anemia poses a challenge. AIM This study was conducted to compare the effects of levonorgestrel releasing (LNG) and copper releasing (Cu T) intrauterine contraceptive devices (IUCD) on body iron stores and menstrual bleeding patterns. METHODS Hundred women desiring contraception were...

OBJECTIVE The study was conducted to identify predictors of oligoamenorrhea at 12 months in levonorgestrel-releasing intrauterine system (LNG-IUS) users. DESIGN A 12-month observational study. SETTING Gynecologic outpatient clinic in a large regional hospital in Flanders, Belgium. POPULATION OR SAMPLE A total of 150 women who had made an informed decision to use a LNG-IUS either as a meth...

OBJECTIVE To review the endometrial safety and patient acceptability of long-term use of continuous transdermal estrogen substitution combined with intrauterine release of levonorgestrel (LNG) in postmenopausal women. DESIGN One-hundred and fifty-three women who utilized the regimen for 2 IUD cycles were followed-up for a period of 10 years. Histology of the endometrium was evaluated at the e...

In a recent paper M. Lopez-Suarez, I. Neri, and L. Gammaitoni (LNG) present a concrete realization of the Boolean Or irreversible gate, but contrary to the standard Landauer principle, with an arbitrary small dissipation of energy. A Popperian good falsification! In this paper we discuss a theoretical description of the LNG gate which is indeed a 3in/3out self–reversible realization of the invo...

OBJECTIVE The contraceptive efficacy of intrauterine devices (IUD) is thought to relate to the position of the IUD in the uterine cavity. Several trials examined the number of copper IUD expulsions, but none evaluated the partial and complete expulsion rate of the levonorgestrel-releasing device (LNG-IUD). STUDY DESIGN This retrospective cohort study compares the dislocation rate of the Multi...

BACKGROUND The insertion of a levonorgestrel-releasing intrauterine system (LNG-IUS) requires experience and is associated with a low failure rate. OBJECTIVES To assess the reasons given by gynecologists why they failed to insert a LNG-IUS. METHODS We obtained data from the sole distributor in Israel that prospectively recorded these cases when contacted by gynecologists following an insert...

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

in this contribution, two approaches are followed to predict the saturated liquid density of liquefied natural gas (lng) mixtures. in one approach, 12 cubic equations of state (eoss), comprising the popular peng-robinson (pr) and redlich-kwong-soave (rks), are employed to predict the saturated liquid density of 20 lng mixtures. in the other approach, these eos are used in conjunction with a rec...
