Amniotic band syndrome is a rare disorder which is thought to be caused by early rupture of the amniotic membrane. The extent of the disease may vary from minor digital amputations to severe lethal anomalies. For many years in routine clinical practice, this syndrome has been diagnosed with two-dimensional ultrasonography. Evolving imaging techniques by means of three-dimensional ultrasonography gives the chance of early and accurate diagnosis of this devastating anomaly. By integrating three-dimensional ultrasonography to the suspected findings diagnosed in the two-dimensional ultrasonography allows us to predict possible outcomes and provides convenience in counselling. Herein we present a case of amniotic band syndrome diagnosed at 19 weeks of gestation with three-dimensional ultrasonography and pregnancy was terminated in the 20th week. Using three-dimensional ultrasonography in certain suspected foetal anomalies may provide the early diagnosis and more accurate knowledge about extent of the disease.

Objective: The study aimed to evaluate the application value of computed tomography (CT) three-dimensional (3D) reconstruction technology in identifying benign and malignant lung nodules and characterizing the distribution of the nodules.
Methods: CT 3D reconstruction was performed for lung nodules. Pathological results were used as the gold standard to compare the detection rates of various lung nodule signs between conventional chest CT scanning and CT 3D reconstruction techniques.

The development of efficient platforms for the evaluation of anti-angiogenic agents is critical in advancing cancer therapeutics. In this study, we exploited an ultrabright semiconducting polymer dots (Pdots) integrating with a three-dimensional (3D) near-infrared-II (NIR-II) fluorescence imaging system designed to assess the efficacy of potent anti-angiogenic agents PX-478 and BPR0C261 in an oral squamous cell carcinoma (OSCC) tumour model, which depends on angiogenesis for dissemination. PX-478, a hypoxia-inducible factor-1α (HIF-1α) inhibitor, and BPR0C261, a microtubule-disrupting agent, were administrated into tumour-bearing mice established using murine MTCQ1 tongue cancer cells through intraperitoneal injection and oral gavage, respectively.

In nature, various molecules possess spiral geometry. Such helical structures are even prevalent within the human body, represented classically by DNA and three-dimensional (secondary structure) protein folding. In this review, we chose helicenes and helicene-like structures -synthetically accessible carbon-rich molecules- as a compelling example of helically chiral scaffolds.

Background: The aim of this study was to evaluate the correlation of the volume and minimum axial area (MAA) measurements between different upper and lower boundaries used for oropharyngeal airway assessment.
Methods: Cone Beam Computed Tomography (CBCT) scans of 49 subjects taken for pre-orthognathic surgical planning were obtained retrospectively from the archives (n = 49; 32 females, 17 males; mean age = 20.9 ± 5.

Objective: To study the biomechanical changes induced by differences in perioral force in patients with missing anterior maxillary teeth at rest via finite element analysis (FEA).
Methods: Using conical beam CT (CBCT) images of a healthy person, models of the complete maxillary anterior dental region (Model A) and maxillary anterior dental region with a missing left maxillary central incisor (Model B) were constructed. The labial and palatine alveolar bone and tooth surface of the bilateral incisor and cusp regions were selected as the application sites, the resting perioral force was applied perpendicular to the tissue surface, and the changes in maxillary stress and displacement after the perioral force was simulated were analyzed.
