Low beta-arrestin expression correlates with the responsiveness to long-term somatostatin analog treatment in acromegalyEuropean Journal of Endocrinology - Tập 174 Số 5 - Trang 651-662 - 2016

AbstractObjectiveThe high expression of somatostatin receptor subtype 2 (SSTR2
also known as sst2) usually present in growth hormone (GH)-secreting adenomas is
the rationale for therapy with somatostatin analogs (SSAs) in acromegaly.
Although SSTR2 expression is a good predictor for biochemical response to SSA
treatment, we still face tumors resistant to SSAs despite high SSTR2 expression.

Quantitative analysis of somatostatin receptor subtype (SSTR1–5) gene expression levels in somatotropinomas and non-functioning pituitary adenomasEuropean Journal of Endocrinology - Tập 156 Số 1 - Trang 65-74 - 2007

Objective: It is believed that the variable effectiveness of somatostatin
analogs in post-surgical management of somatotropinomas and non-functioning
pituitary adenomas (NFPA) may be due in part to variable expression of
somatostatin receptor isoforms (SSTR1–5), within and between pituitary tumor
types. Design and methods: Quantitative real-time RT-PCR was used to compare
absolute mRNA copy number... hiện toàn bộ
STUDIES ON THE METABOLISM OF C-21 STEROIDS IN THE HUMAN FOETO-PLACENTAL UNITEuropean Journal of Endocrinology - Tập 52 Số 4 - Trang 598-606 - 1966
R. Palmera, G. Eriksson, N. Wiqvist, E. Diczfalusy
ABSTRACT Two midterm human placentas were perfused in situ with
pregnenolone-7α-3H sulphate and the unconjugated metabolites present in the
placentas and perfusates were analyzed. Eighty-five and 54% of the radioactive
material recovered from the placentas was in an unconjugated form, whereas only
1 and 3% of that found in the perfusates was unconjugated. Eighty-one and 76% of
the unconjugated mat... hiện toàn bộ
METABOLISM OF DEHYDROEPIANDROSTERONE AND DEHYDROEPIANDROSTERONE SULPHATE BY THE HUMAN FOETUS AT MIDPREGNANCYEuropean Journal of Endocrinology - Tập 52 Số 4 - Trang 583-597 - 1966
E. Bolté, N. Wiqvist, E. Diczfalusy
ABSTRACT Four previable foetuses (18th to 20th week of gestation) were perfused
with a combination of 14C-labelled dehydroepiandrosterone (DHA) and 3H-labelled
dehydroepiandrosterone sulphate (DHAS). Approximately 80% of the radioactive
material administered was recovered from the various foetal tissues and
perfusates. With the exception of the liver, which exhibited an approximately
equal concent... hiện toàn bộ
STUDIES ON THE AROMATISATION OF NEUTRAL STEROIDS IN PREGNANT WOMENEuropean Journal of Endocrinology - Tập 45 Số 4 - Trang 535-559 - 1964

ABSTRACT In 15 cases of therapeutic abortion by laparotomy the placenta was
disconnected from the foetus and perfused in situ with tracer amounts of
radioactive dehydroepiandrosterone (DHA), dehydroepiandrosterone sulphate
(DHAS), androst-4-ene-3,17-dione (A), testosterone (T) and 17β-oestradiol (OE2).
Analysis of the placentas, perfusates and urine samples revealed an extensive

ABSTRACT In situ perfusion of human midterm placentas with labelled pregnenolone
and 17α-hydroxypregnenolone was carried out. Following perfusion with
pregnenolone in two experiments, 80 and 90 per cent of the radioactive material
recovered from the placenta and 25 and 29 per cent of that recovered from the
perfusate was progesterone. These figures accounted for 17 and 13 per cent of
the perfused ... hiện toàn bộ

ABSTRACT In four cases of therapeutic abortion by laparotomy, tracer amounts of
oestrone-6,7-3H and 17β-oestradiol-16-14C were injected into the umbilical vein
20 minutes prior to the interruption of gestation, and the radioactive material
recovered from the placenta and various foetal tissues was analysed. More than

THE DEVELOPMENT OF THE MOUSE OVARY FROM BIRTH TO MATURITYEuropean Journal of Endocrinology - Tập 62 Số 1 - Trang 98-116 - 1969

ABSTRACT Changes occur in the infant ovary which develop the structurally simple
organ at birth to a highly complex one in the maturing animal. The ovary in the
immature mouse is not a dormant organ but one that is characterized by a
continuous growth and development and a concurrent continuous degeneration of
oocytes and follicles. The stroma cells which are present in the ovary at birth
are appa... hiện toàn bộ
EFFECT OF MUSCULAR EXERCISE ON THE PLASMA LEVEL OF CORTISOL IN MANEuropean Journal of Endocrinology - Tập 48 Số 1 - Trang 163-168 - 1965
A Cornil, A. De Coster, Georges Copinschi, J. R. M. Franckson
ABSTRACT Intense muscular exercise performed on a bicycle ergometer by untrained
normal men is accompanied by a significant fall in the plasma cortisol level.
This observation suggests an increased utilization or diffusion of cortisol
during exercise.
Heritability of pubertal timing: detailed evaluation of specific milestones in healthy boys and girlsEuropean Journal of Endocrinology - Tập 183 Số 1 - Trang 13-20 - 2020
Alexander S. Busch, Casper P. Hagen, Anders Juul
Objective Pubertal timing is highly heritable. Observational studies were
inconclusive concerning a potential sex-specific difference in the parental
contribution, while genome-wide association studies highlighted a heterogeneity
in the genetic architecture of pubertal timing between sexes. Our objectives
were to evaluate the association of timing of pubertal milestones in offspring
with parental ... hiện toàn bộ
