Feto-maternal safety of intracervical sodium nitroprusside application in sheep

The feto-maternal safety of sodium nitroprusside (SNP) administration in the cervix of pregnant sheep is evaluated. Chronically catheterized pregnant sheep at approximately 0.9 gestation were divided into 2 groups that received 0.1 mg/kg maternal body weight of SNP gel (2%) or placebo into the internal cervical os. SNP or placebo gel was administered at 9 AM with both maternal and fetal blood gas/pH, and cardiovascular parameters were monitored for 6 hours. Except for a slight transient decrease of maternal oxygen and meta-hemoglobin content, and fetal oxygen content in the SNP group, no other significant changes were observed. However, such changes are minimal and unlikely to be of any clinical significance. Moreover, nitric oxide metabolites were unchanged in both maternal and fetal circulations.These data demonstrate few, if any, effects of intrauterine SNP administration on both cellular oxygenation and cardiovascular indexes. Thus, SNP treatment, once applied into the cervix, could be considered a safe procedure.     

Antiproliferative oleanane saponins from Meryta denhamii

Eight new oleanane saponins (1- 8) together with four know saponins (9-12) were isolated from the aerial parts of Meryta denhamii. Their structures were elucidated by 1D and 2D NMR experiments including 1D TOCSY, DQF-COSY, ROESY, HSQC, and HMBC spectroscopy, as well as ESIMS analysis. The antiproliferative activity of all compounds was evaluated using three murine and human cancer cell lines: J774.A1, HEK-293, and WEHI-164.     

Molecular analysis of the β-catenin gene in patients with the Mayer-Rokitansky-Küster-Hauser syndrome

Purpose

To study the β-catenin gene in a group of Mayer-Rokitansky-Küster-Hauser patients.

Methods

Twelve patients with the Mayer-Rokitansky-Küster-Hauser syndrome were included in this study. DNA was extracted from peripheral blood and the region codifying β-catenin GSK-3β phosphorylation sites on exon 3 was amplified. PCR products were purified and directly sequenced.

Results

No mutations were found in the GSK-3β phosphorylation sites on exon 3 of β-catenin gene in this group of patients with the MRKH syndrome.

Conclusions

β-catenin gene mutations are an unlikely cause of the MRKH syndrome.     

Nitric oxide levels in women with missed and threatened abortion: results of a pilot study

The aim of this study was to evaluate the systemic production of nitric oxide (NO) in missed and threatened abortion and in nonpregnant and regular pregnant controls with the purpose of defining its role in the mechanisms regulating the first-trimester pregnancy toward either positive or negative evolution. Patients with missed abortion showed serum NO levels clearly decreased compared with nonpregnant patients and patients with regular pregnancy and threatened abortion, supporting a direct functional role of the NO mediator in early embryonic development and confirming its importance in the uterus and cervix during abortion.

Very Low Alcohol Consumption Is Associated with Lower Prevalence of Cirrhosis and Hepatocellular Carcinoma in Patients with Non-Alcoholic Fatty Liver Disease

The role of moderate alcohol consumption in the evolution of NAFLD is still debated. The aim of this study is to evaluate the impact of current and lifelong alcohol consumption in patients with NAFLD. From 2015 to 2020, we enrolled 276 consecutive patients fulfilling criteria of NAFLD (alcohol consumption up to 140 g/week for women and 210 g/week for men). According to their current alcohol intake per week, patients were divided in: abstainers, very low consumers (C1: <70 g/week) and moderate consumers (C2). We created a new tool, called LACU (Lifetime Alcohol Consuming Unit) to estimate the alcohol exposure across lifetime: 1 LACU was defined as 7 alcohol units per week for 1 drinking year. Patients were divided into lifelong abstainers and consumers and the latter furtherly divided into quartiles: Q1-Q4. Stratification according to alcohol intake, both current and cumulative as estimated by LACU, showed that very low consumers (C1 and Q1-Q3) displayed lower frequency of cirrhosis and hepatocellular carcinoma compared to abstainers and moderate consumers (C2 and Q4). We can speculate that up to one glass of wine daily in the context of a Mediterranean diet may be a long-term useful approach in selected NAFLD patients.
