Tadalafil for Treatment of Fetal Growth Restriction: A Review of Experimental and Clinical Studies.

Fetal growth restriction (FGR) is a major concern in perinatal care. Various medications have been proposed as potential treatments for this serious condition. Nonetheless, there is still no definitive treatment.

Intravenous lipid emulsion for local anaesthetic systemic toxicity in pregnant women: a scoping review.

Background: Local anaesthetic systemic toxicity (LAST) is a rare but life-threatening complication that can occur after local anaesthetic administration. Various clinical guidelines recommend an intravenous lipid emulsion as a treatment for local anaesthetic-induced cardiac arrest. However, its therapeutic application in pregnant patients has not yet been established.

Positive Ascites Cytology, Postoperative Chemotherapy and Prognosis of Stage I Ovarian Clear Cell Carcinoma.

Background/aim: Ovarian clear cell carcinoma (CCC) is associated with a poor prognosis and is resistant to chemotherapy. The aim of this study was to investigate the prognosis of CCC in Mie prefecture and to identify poor prognostic factors.

Patients And Methods: In this multi-center retrospective study, we analyzed the data of patients with CCC between February 2012 and December 2020.

Evaluation of control of additive concentration in gradient analysis of supercritical fluid chromatography-coupled to tandem mass spectrometry.

Mobile phase additives are used to improve retention behavior in chromatography. In supercritical fluid chromatography (SFC), for which supercritical fluid carbon dioxide (SF-CO) is used as the main mobile phase, additives can only be added into the modifier. For that reason, when gradient analysis is performed by changing the modifier ratio to SF-CO, the additive concentration in the mobile phase increases in parallel with the modifier ratio.

Fetal Biometric Assessment and Infant Developmental Prognosis of the Tadalafil Treatment for Fetal Growth Restriction.

Tadalafil is expected to treat fetal growth restriction (FGR), a risk factor for stillbirth and neonatal morbidity. This study aimed to evaluate the fetal biometric growth pattern of fetuses with FGR treated with tadalafil by ultrasonographic assessment. Materials and : This was a retrospective study.

Awareness of Infectious Disease Screening During Early Pregnancy and Knowledge About its Vertical Transmission in Japan: A Report from the Pregnant Women Health Initiative.

Objectives: We aimed to clarify the accuracy of pregnant women's knowledge and understanding regarding infectious disease screening in early pregnancy and clarify the roles that should be played by health care providers in promoting the health of pregnant women and their children.

Methods: A cross-sectional questionnaire survey was conducted in 25 hospitals across Japan from May 2018 to September 2019. We compared the agreement rates regarding screening results for hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis, human T-cell leukemia virus-1 (HTLV-1), and cervical cytology in the medical records and understanding of their results by pregnant women.

Maternal cardiopulmonary resuscitation.

The perinatal resuscitation history in Japan is short, with the earliest efforts in the field of neonatology. In contrast, the standardization and dissemination of maternal resuscitation is lagging. With the establishment of the Maternal Death Reporting Project and the Maternal Death Case Review and Evaluation Committee in 2010, with the aim of reducing maternal deaths, the true situation of maternal deaths came to light.

Tadalafil treatment for preeclampsia (medication in preeclampsia; MIE): a multicenter phase II clinical trial.

Purpose: To evaluate the effectiveness and safety of tadalafil treatment for hypertensive disorder of pregnancy (HDP).

Materials And Methods: In an open-label, randomized clinical trial, singleton pregnancies with HDP between 20 and 33 weeks of gestation were randomized to take 20 mg oral tadalafil every day (tadalafil treatment group) or no drug (conventional treatment group). The primary outcome was prolongation of pregnancy from randomization to delivery.

Safety Evaluation of Tadalafil Treatment for Fetuses with Early-Onset Growth Restriction (TADAFER): Results from the Phase II Trial.

Tadalafil is a phosphodiesterase 5 (PDE5) inhibitor with a long half-life, high selectivity, and rapid onset of action. Because the safety of using PDE5 inhibitors as therapeutic agents for fetal growth restriction (FGR) has been a problem worldwide, this paper primarily focuses on the safety assessments performed in the Tadalafil Treatment for Fetuses with Early-Onset Growth Restriction (TADAFER) II population. Neonatal and maternal adverse events were analyzed, in addition to fetal, neonatal, and infant death cases, six months after stopping the trial.

Tadalafil treatment in mice for preeclampsia with fetal growth restriction has neuro-benefic effects in offspring through modulating prenatal hypoxic conditions.

We have demonstrated that tadalafil facilitates fetal growth in mice with L-NG-nitroarginine methyl ester (L-NAME)-induced preeclampsia (PE) with fetal growth restriction (FGR). Tadalafil is a selective phosphodiesterase 5 inhibitor that dilates the maternal blood sinuses in the placenta, thereby facilitating the growth of the fetus. The purpose of this study was to investigate the effects of tadalafil treatment for PE and FGR on the developing brain in FGR offspring using an L-NAME-induced mouse model of PE with FGR.

Plasma citrulline is a sensitive safety biomarker for small intestinal injury in rats.

Plasma citrulline is decreased in cases of severe intestinal injury with apparent villus and cellular atrophy. However, the fluctuation of plasma citrulline in slight intestinal injury remains to be investigated. To clarify this, irinotecan at 30 mg/kg or 60 mg/kg was administered intravenously to rats.

Cardiac function and tadalafil used for treating fetal growth restriction in pregnant women without cardiovascular disease.

Background: The aim of the present study was to evaluate tadalafil for the treatment of fetal growth restriction (FGR) and the cardiac function in pregnant women without cardiovascular disease who used tadalafil for this reason.

Materials And Methods: We examined nine pregnant women without cardiovascular disease who were using tadalafil to treat FGR. Maternal heart rate, systolic blood pressure (BP), and echocardiographic findings were assessed before and after tadalafil use.

Pulmonary arterial enlargement predicts cardiopulmonary complications after pulmonary resection for lung cancer: a retrospective cohort study.

Background: The finding of pulmonary arterial enlargement on computed tomography has been reported to be associated with pulmonary hypertension. On the other hand, pulmonary hypertension is a known risk factor for thoracic surgery. We investigated whether pulmonary arterial enlargement predicts cardiopulmonary complications following pulmonary resection for lung cancer.

A validated quantitative liquid chromatography-tandem quadrupole mass spectrometry method for monitoring isotopologues to evaluate global modified cytosine ratios in genomic DNA.

5-Hydroxymethylcytosine (5hmC) and 5-methylcytosine (5mC) represent important epigenetic modifications to DNA, and a sensitive analytical method is required to determine the levels of 5hmC in the genomic DNA of tumor cells or cultured cell lines because 5hmC is present at particular low levels in these cells. We have developed a sensitive liquid chromatography-tandem quadrupole mass spectrometric method for quantifying 5-hydroxymethyldeoxycytidine (5hmdC), 5-methyldeoxycytidine (5mdC), and deoxyguanosine (dG) levels using stable isotope labeled internal standards, and used this method to estimate the global level of 2 modified cytosines in genomic DNA prepared from small number of cells. The quantification limits for 5hmdC, 5mdC and dG were 20pM, 2nM and 10nM, respectively.

IDH1 and IDH2 have critical roles in 2-hydroxyglutarate production in D-2-hydroxyglutarate dehydrogenase depleted cells.

D-2-hydroxyglutaric aciduria (D-2HGA) is a hereditary metabolic disorder characterized by the elevated levels of D-2-hydroxyglutaric acid (D-2HG) in urine, plasma and cerebrospinal fluid. About half of the patients have autosomal recessive mutations in D-2-hydroxyglutarate dehydrogenase (D2HGDH) gene. To analyze the origin of D-2HG in D2HGDH-depleted cells, we used small interfering RNA (siRNA) techniques.

Homozygosity of single nucleotide polymorphisms in the 3' region of the canine estrogen receptor 1 gene is greater in Toy Poodles than in Miniature Dachshunds and Chihuahuas.

Differences in the distribution of single nucleotide polymorphisms (SNPs) and haplotypes in the estrogen receptor α gene (ESR1) were examined in Miniature Dachshunds (n = 48), Chihuahuas (n = 20) and Toy Poodles (n = 18). Five DNA fragments located in the 40-kb region at the 3' end of ESR1 were amplified by polymerase chain reaction and were directly sequenced. We compared allele, genotype and estimated haplotype frequencies at each SNP in the 3' end of ESR1 for these three breeds of small dog.

Comparison of testosterone and insulin-like peptide 3 secretions in response to human chorionic gonadotropin in cultured interstitial cells from scrotal and retained testes in dogs.

Levels of testosterone and insulin-like peptide 3 (INSL3) secretions in response to different doses of human chorionic gonadotropin (hCG) in cultured interstitial cells were compared between retained and scrotal testes in dogs. Retained (n=10) and scrotal (n=9) testes were obtained from small-breed dogs. The testicular tissues were dispersed in Dulbecco's Modified Eagle Medium with Ham's nutrient mixture containing 2000 PU/ml dispase II and 10% fetal bovine serum.

Analysis of single nucleotide polymorphisms in the 3' region of the estrogen receptor 1 gene in normal and cryptorchid Miniature Dachshunds and Chihuahuas.

This study was performed to examine the distribution of single nucleotide polymorphisms (SNPs) and estimated haplotypes in the canine estrogen receptor (ER) alpha gene (ESR1) and the association of them with different phenotypes of cryptorchidism (CO) in Miniature Dachshunds and Chihuahuas. Forty CO and 68 normal dogs were used, and CO was classified into unilateral (UCO; n=33) and bilateral CO (BCO; n=5) or into abdominal (ACO; n=16) and inguinal CO (ICO; n=22). Thirteen DNA fragments located in the 70-kb region at the 3' end of ESR1 were amplified by PCR and sequenced to examine 13 SNPs (#1-#13) reported in a canine SNP database.

Enhancement of prostacyclin synthesis at the beginning of formation of caprine corpora lutea.

We examined changes in the levels of prostacyclin (PGI2) synthase mRNA and 6-keto-PGF1alpha, a stable metabolite of PGI2, in the caprine corpus luteum (CL) during its development and subsequent maintenance. We also looked at the effects of a potent GnRH antagonist (GA), which is known to suppress the release of luteinizing hormone (LH), on the PGI2 synthase mRNA level and the 6-keto-PGF1alpha content during CL development. Goats were divided into a control group (n=12) and a GA-treated group (n=6).

Changes of messenger RNAs encoding vascular endothelial growth factor and its receptors during the development and maintenance of caprine corpora lutea.

The present study was conducted to examine changes of mRNAs encoding vascular endothelial growth factor (VEGF) and its receptors (KDR/Flk-1 and Flt-1), and CD34, which is known to be a specific marker for endothelial cells, during the development and maintenance of the caprine corpora lutea (CL). Effects of a potent GnRH antagonist (GA), which was previously shown to suppress release of luteinizing hormone (LH), on expressions of those mRNAs during the CL development were also investigated. Goats were divided into control (n = 12) and GA-treated groups (n = 6).

Inhibition of luteinizing hormone receptor expression during the development of caprine corpora lutea by administration of gonadotropin-releasing hormone antagonist.

The present study was conducted to examine effects of a potent GnRH antagonist (GA), which suppresses release of luteinizing hormone (LH), on LH receptor expression during the development of the caprine corpus luteum (CL). Goats were divided into control and GA-treated groups. The goats were treated with saline or GA (50 microg/kg, s.
