Ultrasound visualization of the central nervous system during embryonic and fetal periods: Neurosonoembryology utilizing multiple three-dimensional transvaginal ultrasound technology.

Objective: To study the ultrasonographic features of the central nervous system (CNS) in normally developing embryos and fetuses with a crown-rump length (CRL) of 10-84 mm, utilizing a high-frequency transvaginal probe in conjunction with various three-dimensional (3D) imaging modes.

Methods: From January 2020 to February 2021, 210 normally developing embryos and fetuses in early pregnancy were enrolled and classified based on their gestational age. A high-frequency transvaginal transducer was used to perform 2D and 3D ultrasounds, and the 3D images were saved.

Restoration of bladder neck activity and levator hiatus dimensions in Asian primipara: a prospective study.

Pelvic floor muscle training (PFMT) reduces the symptoms in women with pelvic floor dysfunction (PFD); however, the optimal initial timing for secondary prevention of PFD by PFMT is not clear. To identify the optimal timing in Asian primiparas with vaginal delivery, bladder neck descent (BND), levator hiatus areas, and levator hiatus distensibility and contractility were assessed in 26 nulliparous women at 36 weeks of gestation and at 2, 4, 6, and 12 weeks postpartum. We found that BND increased significantly from 2 weeks onwards until 6 weeks postpartum ( 0.

Yolk sac tumor and dysgerminoma in the left gonad following gonadoblastoma in the right gonad in a 46,XY DSD with a novel SRY missense mutation: a case report.

Background: Approximately 10-15% of 46,XY disorders of sex development (DSDs) have an SRY mutation residing in the high mobility group (HMG) domain. Here, we present a case of 46,XY DSD caused by a novel missense mutation in the HMG region of SRY rapidly progressing to germ cell tumors (GCTs).

Case Presentation: An adolescent female (15 years old) exhibiting primary amenorrhea was later diagnosed as a 46,XY female with bilateral gonadal dysplasia on the basis of peripheral lymphocyte karyotype 46,XY and a novel missense mutation in SRY (c.

PLIN2 promotes HCC cells proliferation by inhibiting the degradation of HIF1α.

PLIN2 has been found to be dysregulated in several human malignancies, which influences cancer progression. However, the roles of PLIN2 in regulating hepatocellular carcinoma (HCC) progression are still unclear. Here, we revealed that PLIN2 was frequently upregulated in HCC cells and tissues, and increased PLIN2 expression was associated with poor prognosis outcomes in HCC.

Pharmacokinetics and pharmacodynamics of sildenafil in fetal lambs on extracorporeal support.

Background: Maternal transplacental administration of sildenafil is being considered for a variety of fetal conditions. Clinical translation also requires evaluation of fetal safety in a higher species, such as the fetal lamb. Experiments with the pregnant ewe are curtailed by minimal transplacental transfer as well as limited access to the fetus.

Multiple antiarrhythmic transplacental treatments for fetal supraventricular tachyarrhythmia: A protocol for systematic review and meta analysis.

Background: Fetal supraventricular tachyarrhythmia is a common reason for referral to fetal cardiology. Multiple antiarrhythmic transplacental medications can be used to treat these diseases. Debates remain regarding the standardized therapy.

Low HOXC10 expression in liver cancer regulates proliferation via a mechanism involving miR-221 and the MAPK signaling pathway.

Homeodomain-containing gene 10 (HOXC10) is associated with the progression of a variety of different types of human cancer; however, the role of HOXC10 in liver cancer is not completely understood. The present study aimed to investigate the mechanisms underlying the effects of HOXC10 on liver cancer tumorigenesis. Quantitative PCR and western blotting were used to detect the expression patterns of HOXC10 in cancer and adjacent healthy tissues.

Right aortic arch with mirror image branching accompanied by absent pulmonary valve syndrome and tricuspid stenosis: Prenatal echocardiographic diagnosis of an unusual congenital heart defect.

Right aortic arch (RAA) with mirror image branching (RAMI) accompanied by absent pulmonary valve syndrome (APVS), tricuspid stenosis, and hypoplastic right ventricle is an extremely rare combination of congenital heart anomalies. This combination might result in severe cardiac failure and respiratory compromise, indicating a poor prognosis. Here, we describe a detailed prenatal echocardiographic diagnosis of RAMI accompanied by APVS and tricuspid stenosis.

Nomograms for predicting overall survival and cancer-specific survival in patients with surgically resected intrahepatic cholangiocarcinoma.

Purpose: To develop and validate nomograms for predicting overall survival (OS) and cancer-specific survival (CSS) in patients with surgically resected intrahepatic cholangiocarcinoma (ICC).

Patients And Methods: The nomograms were developed using a development cohort of 947 ICC patients after surgery selected from Surveillance, Epidemiology, and End Results database, and externally validated using a training cohort of 159 patients admitted at our institution. Nomograms for OS and CSS were established based on the independent prognostic factors identified by COX regression models and Fine and Grey's models, respectively.

The binding characteristics of a cyclic nonapeptide, c(CGRRAGGSC), in LNCaP human prostate cancer cells.

Previous studies have demonstrated that interleukin-11 (IL-11) and the IL-11 receptor (IL-11R) are associated with the regulation of tumor progression and may play a significant role in bone metastases. The nonapeptide structure c(CGRRAGGSC) is a phage display-selected IL-11 mimic, which binds to IL-11R. The aim of this study is to investigate the binding characteristics of a cyclic nonapeptide c(CGRRAGGSC) in LNCaP human prostate cancer cells.

A radiolabeled nonapeptide probe targeting PC-3 cells and bone metastases of prostate cancer in mice.

Previous investigations showed that interleukin-11 (IL-11) and the IL-11 receptor (IL-11R) are correlated with regulation of tumor progression and may play significant roles in bone metastases. The nonapeptide structure c(CGRRAGGSC) is a phage-display-selected IL-11 mimic that binds to IL-11R. The aim of this study was to synthesize radiolabeled c(CGRRAGGSC) and to investigate the possible interaction between this radioactive probe and an IL-11R-positive bone metastasis model of PC-3 prostate cancer.

Safety evaluation of 32P-chromic phosphate-poly L lactic acid particles interstitially implanted into livers of Beagle dogs.

Aims: The aim of this study was to investigate the safety and toxicity of biodegradable (32)P-chromic phosphate-poly L lactic acid ((32)P-CP-PLLA) particles interstitially implanted into Beagle dog livers.

Methods: Eighteen healthy Beagle dogs were randomly divided into 6 groups (n=3), and were treated with drugs of different formulations or doses, as well as controls. At different time points after surgery, the experimental dogs were weighed.
