BACKGROUND Levonorgestrel-releasing intrauterine system (LNG-IUS), although inserted to reduce heavy menstruation, causes irregular early transient bleeding. The objective of the study was to document quantitative changes in endometrial vessels of short- (< or =3 months) and long-term (> or =12 months) LNG users. The area, density and maturation of endometrial vessels were quantified in 19 endo...

Abstract A sets of sand column experiments were conducted to investigate the transport and deposition of colloids in water-saturated porous media, and the mechanism of the permeability reduced by transport and deposition of colloids are discussed. The research results show that the breakthrough curves of colloid transport in water-bearing media presented as three stages: “not-yet-breakthrough”,...

Progestins provide safe, effective and cheap options for contraception as well as the treatment of a variety of gynaecological disorders. Episodes of irregular endometrial bleeding or breakthrough bleeding (BTB) are a major unwanted side effect of progestin treatment, such that BTB is the leading cause for discontinued use of an otherwise effective and popular medication. The cellular mechanism...

OBJECTIVE To study cycle control, compliance and safety of a transdermal contraceptive patch in Thai women. MATERIAL AND METHOD Sixty-nine healthy women were assigned to receive 3 cycles of contraceptive patch (ethinyl estradiol 20 microg and norelgestromin 150 miccrog/day). All participants aged 18-45 years were invited to participate at the family planning clinic at King Chulalongkorn Memor...

Currently, Contraceptive agents play a key role in family planning in India. Hormonal contraception is the marketed most common birth control option in women. An estimated 100 million women throughout the world use hormonal contraceptives for prevention of pregnancy. This article briefly describes the recent advances in hormonal contraceptive strategies that may minimize side effects while opti...

Endometriosis is characterised by the benign growth of endometrial glands and stroma on the surface of peritoneal tissues and other organs. It is generally regarded as an aberrant estrogen-dependent growth condition, which presents with symptoms of chronic pelvic pain, bleeding and infertility. Steroidal progestogens are already widely used in the treatment of the condition, dienogest (Visanne)...

Seizures are one of the commonest neurological symptoms seen in children. Recurrent seizures could ensue from epilepsy, febrile seizures, provoked seizures, drug inefficacy or with, or due to unknown or systemic illnesses [1]. A breakthrough seizure is an epileptic seizure that occurs, despite the use of anticonvulsants that have otherwise successfully prevented seizures in the patient. Breakth...

in this study, bimodal meso-porous silica (uvm-7) synthesized and fabricated amino silane modified supports were characterized by powder x-ray diffraction (xrd), n2 adsorption/desorption, transmission electron microscope (tem), elemental analysis and titration. capacity of co2 capture on modified bimodal pore structure silica at 70°c was calculated using breakthrough curves; and it was found th...

background: technetium-99m radioisotope is the backbone of any nuclear medicine institute. this radioisotope is acquired by the elution of molybdenum-99/technetium-99m generator which emits 141 kev gamma ray and having 6.04 hour half-life. occasionally the contents of molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. this...

Adverse effects of hormonal contraceptives usually diminish with continued use of the same method. Often, physi- cians only need to reassure patients that these symptoms will likely resolve within three to five months. Long-acting injectable depot medroxyprogesterone acetate is the only hormonal contraceptive that is consistently associated with weight gain; other hormonal methods are unlikely ...
