Asymmetric XMoGeY2 (X = S, Se, Te; Y = N, P, As) monolayers as potential flexible materials for nano piezoelectric devices and nanomedical sensors.

Highly efficient nano piezoelectric devices and nanomedical sensors are in great demand for high-performance piezoelectric materials. In this work, we propose new asymmetric XMoGeY2 (X = S, Se, Te; Y = N, P, As) monolayers with excellent piezoelectric properties, dynamic stability and flexible elastic properties. The piezoelectric coefficients (d11) of XMoGeY2 monolayers range from 2.92 to 8.19 pm V-1. Among them, TeMoGeAs2 exhibits the highest piezoelectric coefficient (d11 = 8.19 pm V-1), which is 2.2 times higher than that of common 2D piezoelectric materials such as 2H-MoS2 (d11 = 3.73 pm V-1). Furthermore, all XMoGeY2 monolayers demonstrate flexible elastic properties ranging from 96.23 to 253.70 N m-1. Notably, TeMoGeAs2 has a Young's modulus of 96.23 N m-1, which is only one-third of that of graphene (336 N m-1). The significant piezoelectric coefficients of XMoGeY2 monolayers can be attributed to their asymmetric structures and flexible elastic properties. This study provides valuable insights into the potential applications of XMoGeY2 monolayers in nano piezoelectric devices and nanomedical sensors.

Comparison of Lugano Criteria Versus RECIL and PERCIST as Prognostic Factors in Diffuse Large B-Cell Lymphoma.

OBJECTIVE: This study aimed to compare the criteria of the Lugano, RECIL, and PERCIST for prognosis in patients with diffuse large B-cell lymphoma. PATIENTS AND METHODS: We retrospectively evaluated 335 patients with diffuse large B-cell lymphoma. All patients underwent baseline 18 F-FDG PET/CT. Among them, 252 and 213 patients underwent interim PET/CT (I-PET/CT) and end-of-treatment PET/CT (EoT-PET/CT), respectively. Scans were interpreted by 2 nuclear medicine physicians using Lugano, RECIL, and PERCIST. RECIL and PERCIST were compared with Lugano for predicting progression-free survival (PFS) and overall survival (OS). RESULTS: All 3 response criteria could be used to predict PFS and OS. In I-PET/CT, the concordance index of Lugano in predicting PFS and OS was higher than that of RECIL (both P = 0.043) or PERCIST ( P = 0.008 and P = 0.034, respectively). In EoT-PET/CT, the concordance index of Lugano for predicting PFS and OS was similar to RECIL and not significantly different from PERCIST ( P = 0.597 and P = 0.231, respectively). CONCLUSIONS: For I-PET/CT, using the Lugano criteria is more accurate than RECIL or PERCIST in predicting PFS and OS. However, for EoT-PET/CT, the PERCIST criteria are minimally better.

Ultrasonographic measurement of the effect of physical training on ligament injuries / Medição ultrassonográfica do efeito do treinamento físico nas lesões ligamentares / Medición ecográfica del efecto del entrenamiento físico en las lesiones de ligamentos

ABSTRACT Introduction: The ankle joint is the most load-bearing joint of the human body. The health consciousness of people is increasing day by day, the probability of ankle sports injuries is also increasing. Objective: Analyze the applying sports medicine ultrasound value to rehabilitate anterior talofibular tendon injury. Methods: Seventy- two patients with anterior talofibular injury in a particular hospital were divided into control and observation groups to observe the effect of recovery, recovery time, and degree of ligament injury during rehabilitation treatment. Results: In the observation group, the complete recovery rate was 91.67%, incomplete recovery (8.33%), recovery time was (2.36±0.9) months. The complete recovery rate of the control group is (77.78%), the incomplete recovery (22.2%), the recovery time (3.58±0.42) months. Patients in the experimental group had a higher grade of ligament injury III than those in the control group during each rehabilitation period; the difference was statistically significant (P<0.05). Conclusions: Sports medical ultrasound can determine the degree of anterior talofibular ligament rupture after injury, providing a basis for the clinical formulation of the treatment plan.

RESUMO Introdução: A articulação do tornozelo é a articulação do corpo humano que mais suporta carga. A consciência da saúde das pessoas está aumentando de dia para dia, a probabilidade de lesões esportivas no tornozelo também está aumentando. Objetivo: Analisar o valor de aplicação do ultra-som de medicina esportiva para a reabilitação de lesão no tendão talofibular anterior. Métodos: Setenta e dois pacientes com lesão talofibular anterior em um determinado hospital foram divididos em grupos de controle e observação para observar o efeito da recuperação, o tempo de recuperação e o grau de lesão ligamentar durante o tratamento da reabilitação. Resultados: No grupo de observação, a taxa de recuperação completa foi de 91,67%, a recuperação incompleta (8,33%), o tempo de recuperação foi de (2,36±0,9) meses. A taxa de recuperação completa do grupo de controle é de (77,78%), a recuperação incompleta (22,2%), o tempo de recuperação (3,58±0,42) meses. Os pacientes do grupo experimental tiveram maior grau de lesão ligamentar III do que os do grupo controle durante cada período de reabilitação, a diferença foi estatisticamente significativa (P<0,05). Conclusões: A ultra-sonografia médica esportiva pode determinar o grau de ruptura do ligamento talofibular anterior após a lesão, fornecendo uma base para a formulação clínica do plano de tratamento.
