PURPOSE To evaluate whether type and location of placenta previa affect risk of antepartum hemorrhage-related preterm delivery. METHODS We retrospectively studied 162 women with singleton pregnancies presenting placenta previa. Through observation using transvaginal ultrasound the women were categorized into complete or incomplete placenta previa, and then assigned to anterior and posterior g...

Intrauterine growth of fetus mainly depends on adequate function of placenta. Placenta is a fetal organ. It shares same stress and strain to which the fetus is exposed. Thus any disease which affects the mother has a great impact on placenta. Anatomical structure of placenta greatly influences its function. Thus study of placental morphology is considered essential. 136 Pregnancy complications ...

BACKGROUND: Microplastics are able to enter the human body through food chains, personal care products, contact (skin) from soil, water or inhalation of microplastics in air. AIM: This article aims identify presence that exposed humans. METHODS: Systematic review using four bibliographic databases (Google Scholar, Wiley Online Library, PubMed, and Science Direct). Literature search 2016 2021, f...

Retained placenta is a common complication of the third stage of labor. Most literature has focused on management of a trapped placenta or placenta accreta. The most common source of a trapped placenta is from a partial closure of the cervix and/or a contracted lower uterine segment. We present an unusual case of a retained placenta trapped in a septate uterus. The management included unsuccess...

Objective: To review the use of transvaginal ultrasound for the diagnosis of placenta previa and recommend management based on accurate placental localization. Options: Transvaginal sonography (TVS) versus transabdominal sonography for the diagnosis of placenta previa; route of delivery, based on placenta edge to internal cervical os distance; in-patient versus out-patient antenatal care; cercl...

the human placenta has long been the subject of scientific interest due to the important roles which it performs during pregnancy in sustaining the fetus and maintaining fetomaternal tolerance. more recently, however, researchers have begun to investigate the possibility that the placenta’s utility may extend beyond fetal development to act as a source of cells with clinically relevant properti...

When viewed from the top, Trichodina is circular; side views of the organism reveal a saucer or dome shape (Fig. 1). It has three rings of cilia (small, hair-like projections) encircling its body and oral cavity, which are used for locomotion and feeding. Its body is supported by a rigid ring of interconnected discs called a chitinoid or denticular ring (Fig. 2). Each disc has a thorn-like inne...

In this paper, we study the influence on the ring-like vortex structure in MVG controlled supersonic ramp flow by different inflow conditions. In front of the MVG, three turbulent inflow profiles with different boundary layer thickness are generated as the inflow. From the shape factors, we can see that these inflows in front of the MVG are fully developed turbulent. It is found that the inflow...

Using 300 nm nanosphere monolayer mask on COOH terminated silane surface as mask, we fabricate a chemical pattern which has polyethyleneglycol (PEG) terminated surface patterned with carboxylic terminated holes. Lysozyme selectively absorbs on the COOH terminated holes forming a hexagonal packed lysozyme monolayer array. The patterned protein islands cover the whole 1x1 cm wafer and have a ring...

Placenta previa can be difficult to diagnose with transabdominal sonography during the third trimester of pregnancy, because of difficulties in imaging the cervix late in pregnancy. Although transperineal sonography offers an additional view of the cervix, its value in the diagnosis of placenta previa has not been studied. Accordingly, we performed transperineal sonography on 164 patients who h...
