In the present work, we theoretically demonstrate that near-field radiative heat transfer (NFRHT) can be modulated and enhanced by a new energy transmission mode of evanescent wave, i.e. the nonrec...

Interrupted aortic arch (IAA) is a rare complex congenital heart disease characterized by interrupted continuity between ascending aorta and descending aorta. Prenatal diagnosis of IAA by echocardiography is not uncommonly reported despite its rarity. However, employing four-dimensional ultrasound HD-flow imaging and spatiotemporal image correlation (STIC) in diagnosis of this condition has seldom been reported. We report a case of fetal IAA prenatally diagnosed by two-dimensional echocardiography and HD-flow STIC.

Vascular ring and sling are congenital anomalies of the vascular structure in the thorax with a prevalence of 2.4/10,000 live births. Double aortic arch (DAA), right aortic arch with left ductus arteriosus and aberrant left subclavian artery (RAA-ALSA), and pulmonary artery sling (PAS) are the three common types of vascular ring and sling. These anomalies can be isolated or accompanied by intracardiac malformation. The presence of both vascular ring and PAS is extremely rare. Here, we report a fetus who was prenatally diagnosed with PAS and RAA-ALS, and developed symptoms due to esophageal and airway compression after birth.

We calculate the near-field radiative heat transfer (NFRHT) between two charged metallic plates with an external electric field oriented perpendicular to the plates. The near-field radiative heat flux is discussed in detail for gold, silver, and copper plates. The results show that the NFRHT between the copper plates is the largest. Due to the coupling between electrostatic interactions and surface fluctuations, the p-wave heat flux is amplified by several orders of magnitude by the perpendicular electric field. With increasing electric-field strength, the heat flux between the copper plates increases rapidly to a maximum value. Moreover, for a separation between the copper plates of 10–20 nm, the magnitude of the perpendicular electric field corresponding to the maximal heat flux increases exponentially with plate separation. We study how to use the external electric field to control the NFRHT between metal plates, which has a wide range of applications in thermal nano-devices.

Modulating the photonic transmission coefficient (PTC) is a critical factor in regulating the near-field radiative heat transfer (NFRHT) between two objects. Extending previous studies, we find that multiple body-vacuum interfaces can support various resonance modes and flexibly amplify the PTC. We show that black phosphorus (BP)/vacuum multilayers support coupled multiple anisotropic surface plasmon polaritons (MASPPs) and propose a theoretical model of a pattern-free noncontact thermal modulator based on the mechanical twist between two BP/vacuum multilayer structures. The various symmetric and antisymmetric branches of MASPPs strengthens the PTC, and with it the NFRHT. We also analyze the combined effects of the number of layers and twisted angle. Changing the integral twisted angle and inter-layer twisted angle modulates the positions and intensities of MASPPs. In addition to the twist between the emitter and receiver, the inter-layer twist gives the BP/vacuum multilayer heat transfer system another pathway to modulate the NFRHT. These results pave the way for using two-dimensional anisotropic materials to actively manipulate heat currents.

Persistent truncus arteriosus (PTA) is a relatively uncommon congenital heart disease, accounting for approximately 0.7-1.4% of all congenital cardiac abnormalities worldwide. PTA is usually accompanied by a single semilunar valve, with leaflets ranging from one to six in number. However, absent semilunar valve (ASV) is rarely seen in PTA. Here, we report a case of prenatally diagnosed PTA accompanied by ASV (PTA-ASV) confirmed by postmortem autopsy.

To evaluate the accuracy of oblique view extended imaging (OVEI) in locating the position of the fetal conus medullaris. One hundred and twenty-two normal fetuses and five counterparts with spinal bifida received prenatal ultrasound examination. The vertebral body at the terminal of the conus medullaris and the coronal section of over five vertebral bodies were reconstructed using OVEI. Development of the nervous system of normal fetuses was assessed at postnatal day 28. For spinal bifida cases, pathological examination was performed. Among 127 fetuses, the conus medullaris was accurately positioned in 120 (94.0%) cases according to OVEI. OVEI failed to locate the conus medullaris in three healthy fetuses due to obesity of the mother and four cases with spinal bifida due to abnormal fetal position. The conus medullaris was located at L3 or above in 115 healthy fetuses. The conus medullaris was positioned below L4 in five fetuses with spinal bifida, including L5 in two, S1 in two, and S3 in one, which was consistent with the findings of pathological examination. OVEI can display the 12th rib, T12, and conus medullaris simultaneously. OVEI is applicable to precisely locate the position of the conus medullaris and useful for prenatal evaluation of spinal bifida.

Pulmonary atresia with ventricular septal defect (PA-VSD) is a rare complex congenital heart defect. Major artery-pulmonary collateral arteries (MAPCAs) are characteristic of PA-VSD. Prenatal diagnosis can be achieved in most cases of PA-VSD with recent advances in echocardiography. However, it is extremely rare that all MAPCAs can be observed on the echocardiograph. Here, we report a case of prenatally diagnosed type C PA-VSD in which all the MAPCAs could be seen on the echocardiograph, with the diagnosis supported by autopsy evidence.

This study meta-analyzed the literature on possible association of polymorphisms -137 (rs187238) and -607 (rs1946518) in the interleukin-18 (IL-18) promoter with risk of hepatocellular carcinoma (HCC). The analysis included 8 case-control studies on the -137 polymorphism (1,318 cases, 2,254 controls) and 7 case-control studies on the -607 polymorphism (1,262 cases, 1,696 controls). None of the five genetic models suggested a significant association between the -137 polymorphism and HCC risk: allelic model, OR 0.99, 95% CI 0.74–1.34, P = 0.97; recessive model, OR 0.98, 95% CI 0.65–1.46, P = 0.91; dominant model, OR 1.35, 95% CI 0.73–2.52, P = 0.34; homozygous model, OR 0.99, 95% CI 0.65–1.49, P = 0.95; heterozygous model, OR 0.99, 95% CI 0.66–1.48, P = 0.94. Similar results were obtained in subgroup analyses of Asian patients, Chinese patients, or patients with hepatitis B virus (HBV)-related HCC. Similar results were also obtained for the -607 polymorphism across the entire study population as well as in the three subgroups. The available evidence suggests no significant association of the -137 or -607 polymorphisms with risk of HCC in general or specifically of HBV-related HCC. These conclusions should be verified in large, well-designed studies.
