SUMMARY The concentration of progesterone receptors in rat uterine cytosol and nuclei was measured during the oestrous cycle and pregnancy. The method used allowed the measurement of the total concentration of binding sites (unbound and hormone-bound). During the oestrous cycle, the concentration of receptors in the cytosol peaked at pro-oestrus, low concentrations were observed at oestrus and metoestrus, and an increase was seen at dioestrus. In the nuclei, maximum concentrations occurred at pro-oestrus and dioestrus. The number of receptors in the cytosol was very low during the first half of pregnancy, but the concentration increased progressively after day 15 to attain a very high level (about 26 000 binding sites/cell) on day 22. In the nuclei, the concentration of receptors was low at the beginning of pregnancy. On day 5 (day of implantation) there was a slight increase, which corresponded to a decrease in the number of cytosolic receptors and a small peak in the level of progesterone in the plasma. Maximum concentrations were attained during a 'plateau' period between days 9 and 15. Thereafter, there was a decrease in the concentration of nuclear receptors and on day 22, the mean value was very low; in some animals, probably on the verge of parturition, no receptors were detectable in the nuclei.

Background:The lipid paradox is termed the decreased cholesterol level in rheumatoid arthritis (RA). Nevertheless, the apolipoprotein levels are usually higher than a healthy person and are predictors of cardiovascular events.Objectives:We aimed to describe lipid abnormalities in RA patients and to look for predictor factors of these changes.Methods:The prospective study was carried out on patients with RA who met the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria. These patients were followed in the rheumatology department of the Kassab Institute.We collected the socio-demographic data, biological and immunological parameters.The lipid assessment included: a measurement of total cholesterol (TC), HDL, LDL, and triglycerides (TG). Lipoproteins APOA1 and APOB were measured. All data were collected after patient consent.Results:Of the 47 patients recruited, 78.7% were female. The mean age was 52.5 ±11.06 [32-76]. The average RA progressed from 86.25 ±63 months [5-288] and was erosive in 81.6% of cases. The rheumatoid factor (RF) was positive in 57.8% of patients, and citrullinated antipeptide antibodies (ACPA) were present in 62.2%. Eight patients had a previous CV history.Mean TC was 4.42 ±1.3 [1.2-7.58], mean HDL was 1.38 ±0.73 [0.18-4.10], mean LDL was 2.55 ±1.16 [0.24-5.54]. The mean TG value was 1.28 ±0.6 [0.24-5.54]. TC elevation was found in 9.1% of cases, HDL in 21.3% of cases, LDL in 5.5% of cases, and TG in 16.4% of cases. Mean APOB/APOA1 ratio was 0.67 ±0.18 [0,46-1,11]. LDL elevation was associated to a high DAS28 (p=0.06, r=0.512). APOA1 was associated to a low DAS28 (p=0.04, r=-0.642).The mean value of APO A1 was 1.36 ±0.21 [0.84-1.81], that of APOB was 0.90 ±0.22 [0.58-1.40]. APOA1 values were lower in patients with high-level LDL (p=0.767). The APOB value was associated with lipid disturbance without significant correlation (p=0.291).Conclusion:Lipid test abnormalities can be found in RA patients outside of any known CV risk factors. APOA1 seems to have a protective effect. Screening and treatment of these abnormalities can prevent CV risk.References:[1]Miguel Bernardes and al.

An ammonia loading rate of 4.1 kg N-NH4+/m3d was fully oxidized to nitrate using a nitrifying airlift without biomass carrier. The developed sludge, with a concentration of 12 gVSS/L and high density (100 gVSS/Lparticle), allowed particles to be retained with small diameter, having very low concentrations of solids in the effluent (5–10 mg VSS/L). The mean diameter of particles containing the majority of total biomass increased from 220 to 360 m during the operation time. The particle size analysis showed that the percentage of flocs with small diameter (1–3 m) is very high but the biomass content of these flocs is negligible with respect to the total biomass value. The oxygen transfer coefficient (KLa) was measured operating at different air flow rates, obtaining similar values during the overall operational period. The use of activated sludge without support gives high nitrifying rates with an easier fluidization and a lowercritical air flow rate than in a biofilm airlift reactor.

Achieving sustainable development in the water–energy–food (WEF) nexus is gaining global attention. The coupling and coordination degrees are a way to measure sustainable development levels of a complex system. This study assessed the coupling and coordination degrees of the core WEF nexus and identified key factors that affect sustainable development. First, an index system for assessing coupling and coordination degrees of the core WEF nexus was built. Second, the development levels of three subsystems as well as the coupling and coordination degrees of the core WEF nexus in China were calculated. The results showed that from 2007 to 2016, the mean value of the coupling degree was 0.746 (range (0.01, 1)), which was a high level. This proved that the three resources were interdependent. Hence, it was necessary to study their relationship. However, the mean value of the coordination degree was 0.395 (range (0, 1)), which was a low level. This showed that the coordination development of the core WEF nexus in China was low. It is necessary to take some measures to improve the situation. According to the key factors that affect the development levels of water, energy, and food subsystems, the authors put forward some suggestions to improve the coordination development of the WEF system in China.

ABSTRACT Progesterone and human chorionic gonadotrophin (HCG) were measured in the sera of 25 patients with hydatidiform mole, 10 patients with choriocarcinoma and 200 normal pregnancies by a competitive protein-binding assay and a haemagglutination-inhibition assay respectively. Elution of the petroleum ether extract of mole serum on Sephadex LH-20 showed that the main fraction (92.8%) was progesterone, followed by a small peak of 20 α-hydroxyprogesterone. In 21 intact hydatidiform moles, the mean serum progesterone of 106.0 ng/ml (range 17.8–263 ng/ml) was higher than for normal pregnancy. Serum HCG (mean 833 IU/ml) was similarly elevated. Low concentrations of progesterone (0–17.3 ng/ml) and HCG (15–160 IU/ml) were present in 4 patients who had aborted. The mean serum progesterone was not further elevated in patients with theca lutein cysts of the ovary. There was no correlation between the serum progesterone and the uterine size, serum HCG or malignant sequelae. In 10 cases of choriocarcinoma, the serum progesterone ranged from 1.3–61 ng/ml (mean 16.9 ng/ml), the serum HCG from 0–960 IU/ml (mean 158 IU/ml) but there was no correlation between the two values. The evidence suggests a hyperactive steroidogenesis in hydatidiform mole and poor steroidogenesis in choriocarcinoma. An HCG secretion occurs in both cases.

We present 19 ray lengthenings in 14 patients done with a small external fixator. In six cases the thumb was lengthened and in the other 13 cases, other digital rays. The most frequent reason for lengthening was an amputation sustained in a work accident. All the lengthenings were done by an osteotomy and subsequent gradual distraction with a small external fixator. The mean lengthening achieved was 20 mm (range, 0–32). An iliac-crest graft was needed in nine cases, corrective osteotomy in five cases and a deepening of the web in the six cases of thumb lengthening. In five cases an additional technique was needed to achieve bony consolidation. We have analysed the functional results and the ability to perform activities of daily living and resume employment. Although most of the patients had multiples injuries, the results have been very favourable, achieving a very high level of patient satisfaction.

A reproducible radioimmunoassay procedure for the determination of anti-acetylcholine receptor antibodies in the sera of patients with myasthenia gravis is described and examined in detail. The assay combines features of a number of methods previously outlined and allows repeat determinations of antibody titre in a given myasthenic serum sample with coefficient of variation 6%. The mean ± standard deviation for normal human serum anti-acetylcholine receptor antibodies was found by this procedure to be 0·024 ± 0·033 nmol/l α-bungarotoxin binding sites whereas the range for myasthenic patients was 0–139·14 nmol/l with a mean value of 7·55 nmol/l α-bungarotoxin binding sites.
