Three-Dimensional Evaluation of Soft Tissue Malar Modifications after Zygomatic Valgization Osteotomy via Geometrical Descriptors.

J Pers Med 2021 Mar 13;11(3). Epub 2021 Mar 13.

Department of Surgical Sciences, Division of Maxillofacial Surgery, University of Turin, Città della Salute e della Scienza HOSPITAL, 10129 Turin, Italy.

Patients with severe facial deformities present serious dysfunctionalities along with an unsatisfactory aesthetic facial appearance. Several methods have been proposed to specifically plan the interventions on the patient's needs, but none of these seem to achieve a sufficient level of accuracy in predicting the resulting facial appearance. In this context, a deep knowledge of what occurs in the face after bony movements in specific surgeries would give the possibility to develop more reliable systems. Read More

College of Material Science and Engineering, Sichuan University of Science and Engineering; Material Corrosion and Protection Key Laboratory of Sichuan province, Zigong 643000, China.

Flexible and stretchable strain sensors are crucial components for wearable electronics that can detect and quantify the stimuli from the environment and thus realize the rapid feedback and control of smart devices. However, reconciliation of the conflict between resourceful design of conductive networks and large-scale production in the industry still faces a huge challenge. Herein, we present a new flow-manipulated strategy to prepare a wearable strain sensor featuring a helically intersected conductive network, which exhibited easy integration, multidimensional sensibility, and robust mechanical properties.

Department of Obstetrics and Gynecology, University ''Campus Bio-Medico'' of Rome, Via Alvaro del Portillo, 200-00128 Rome, Italy.

Even though 80% of patients with High-Grade Serous Ovarian Cancer respond to standard first-line chemotherapy, a majority of them could relapse in the following five years due to a resistance to platinum. Human Epididymis protein 4 (HE4) is one of the most promising markers in predicting platinum therapy response. This pilot study aims to evaluate the potential role of HE4 value in predicting chemotherapy response in mutated patients and in wild-type (non-mutated) ones. Read More

Umbilical cord lactate compared with pH as predictors of intrapartum asphyxia.

Exp Ther Med 2021 Jan 26;21(1):80. Epub 2020 Nov 26.

Department of Obstetrics and Gynecology, 'Carol Davila' University of Medicine and Pharmacy, 020021 Bucharest, Romania.

Despite advances in fetal monitoring during labor, one of the most critical causes of neonatal death and neurologic injuries remains intrapartum asphyxia. Umbilical cord gases can be used to detect acidosis and fetal distress. We conducted a retrospective, multicenter study to evaluate umbilical cord blood pH and lactate as a mean of evaluating the degree of intrapartum hypoxia and also to establish which of the two is more reliable in predicting morbidity in term neonates.

Entropy (Basel) 2020 May 7;22(5). Epub 2020 May 7.

Department of Biomedical Sciences for Health, Università degli Studi di Milano, 20133 Milan, Italy.

The surface electromyography (sEMG) records the electrical activity of muscle fibers during contraction: one of its uses is to assess changes taking place within muscles in the course of a fatiguing contraction to provide insights into our understanding of muscle fatigue in training protocols and rehabilitation medicine. Until recently, these myoelectric manifestations of muscle fatigue (MMF) have been assessed essentially by linear sEMG analyses. However, sEMG shows a complex behavior, due to many concurrent factors. Read More

Psychol Rep 2020 Oct 28:33294120965461. Epub 2020 Oct 28.

Leeds School of Social Sciences, Leeds Beckett University, Leeds, UK.

Interoception, the ability to detect internal bodily signals, is vital for an individual's well-being and is increasingly connected to mental health disorders. Research investigating relationships between individual differences in interoception and personality types is limited, and mixed results are reported across a variety of interoceptive tasks, measures, and conceptualisations. Guided by biological theories, this study contributed further to the understanding of the relationship between interoception and personality by utilising two interoceptive measures. Read More

Provincial Key Laboratory of Advanced Energy Materials, College of Chemistry, Northeast Normal University, Changchun, 130024, P. R. China.

A series of [email protected] composites were synthesized through in situ encapsulation of luminous rhodamine B (RhB) molecules into a blue-emissive zirconium-naphthalene-based metal-organic framework (Zr-MOF). The fabricated [email protected] composites exhibit tunable dual-emissive characteristics due to the process of resonant energy transfer from Zr-MOF to RhB. Notably, one of the [email protected] composites ([email protected]) exhibited a weak emission at 420 nm and a strong emission at 607 nm, for which the two emissions possess large distinctions in location and intensity and can be referenced with each other in sensing analytes.
