زمینه و هدف: پارگی زودرس پرده های جنینی (prom) به پارگی پرده های جنینی در هر زمان از بارداری قبل از شروع دردهای زایمانی اطلاق می شود که در 25-2% بارداریها رخ می دهد. با توجه به عوارضی مانند زایمان زودرس و مرگ های حول و حوش زایمان ناشی از پارگی پیش از موعد پرده های جنینی (prom) اهمیت تشخیص درست و به موقع آن و نیز نتایج مثبت و منفی کاذب بالای روش های تشخیصی موجود، این تحقیق با هدف مقایسه قدرت تشخ...
Aim. To analyse the levels of serum beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein A (PAPP-A) in pregnant women without fetal chromosomal abnormalities with trisomy 21 (Down syndrome) or 18 (Edwards syndrome). Materials Methods. We performed a retrospective analysis biochemical parameters 1214 who had previously undergone karyotyping as part prenatal postnatal...
Vertical-cavity surface-emitting lasers (VCSELs) have been widely used in consumer electronics, light detection and ranging, optical interconnects, atomic sensors, so on. In this paper, a VCSEL with the surface metastructure like one-dimensional high-contrast grating (HCG), based on HCG-DBR vertical cavity, was first designed fabricated. The polarization characteristic of HCG-VCSEL were experim...
BACKGROUND hCG is a wonder. Firstly, because hCG is such an extreme molecule. hCG is the most acidic glycoprotein containing the highest proportion of sugars. Secondly, hCG exists in 5 common forms. Finally, it has so many functions ranging from control of human pregnancy to human cancer. This review examines these molecules in detail. CONTENT These 5 molecules, hCG, sulfated hCG, hyperglycos...
Aim Outside of Japan, recombinant-human chorionic gonadotropin (r-hCG) is widely used for the induction of final follicular maturation and early luteinization in women undergoing ovulation induction; whereas in Japan, urine-derived hCG (u-hCG) is predominantly used. The primary objective of this study was to demonstrate the non-inferiority of r-hCG to u-hCG for ovulation induction, as assessed ...
Purpose Recombinant hCG (r-hCG) was approved in Japan in 2016. As a prerequisite for a Phase III study in Japan related to this approval, the pharmacokinetic (PK) profile of r-hCG was investigated. Methods An open-label, partly randomized, single-center, single-dose, group-comparison, Phase I PK-bridging study was done that compared a single 250 μg dose of r-hCG with a single 5000 IU dose of ...
Multiple hCG-related molecules are present in pregnancy serum and urine samples. These include non-nicked hCG (the hormone), nicked hCG, hyper- and hypoglycosylated hCG, hCG missing the C-terminal extension, free alpha-subunit, large free alpha-subunit, free beta-subunit, nicked free beta-subunit, and beta-core fragment. Over 100 immunoassays are sold for quantifying hCG-related molecules in se...
Previous investigations of patients with gestational trophoblastic neoplasia have shown that their urines often contain carboxyterminal peptide (CTP) fragments of the choriogonadotropin (hCG) beta-subunit as well as forms of hCG deficient in sialic acid. In order to determine whether beta-CTP fragments are among the urinary products of the peripheral degradation of desialylated hCG (as-hCG), us...
زمینه و هدف: امروزه ایمن‌ترین و دقیق‌ترین راه تعیین جنسیت سونوگرافی است. زودترین زمانی که سونوگرافی می‌تواند جنسیت را تشخیص دهد، ابتدای سه ماهه دوم بارداری است. چنانچه بتوان با روش‌های آزمایشگاهی نظیر بررسی تیتر بتا را خیلی زود و در مراحل ابتدایی بارداری و حتی قبل از سونوگرافی تشخیص داد، می‌توان اقدام به سقط قانونی و جلوگیری از تولد نوزاد بیمار نمود. هدف از این مطالعه ارتباط سطح گنادوتروپ...
