Currently, there are no studies providing data on normal thyroid anatomy images on ultrasound to document thyroid imaging for doctors in the country in general and in the Mekong River Delta in particular. Therefore, it is necessary to determine the size of a normal adult human thyroid gland by ultrasound and contribute to providing reference data for the training of clinicians, especially determining the dose of drugs to treat some thyroid diseases related to the size of the gland.

Nowadays, there are many factors causing the decrease of male reproductive function such as diet, routine, chemical, ... But some of them have not been paid appropriate attention to, especially the use of paracetamol, which has a significant negative effect on the reproductive process. In this study, we will summarize the results of several studies on the harmful effects of prolonged high-dose use of paracetamol on sperm number, quality, portability and testicular morphology in experimental animals and humans.

This paper examines the Dirichlet problem for augmented k-Hessian equations in exterior domains. Building upon our previous results on the viscosity solutions to the Dirichlet problems for augmented k -Hessian equations in the bounded domain, and L. Dai, J. Bao's method to the k-Hessian equations in exterior domains, a sufficient condition for the existence and uniqueness of viscosity solutions to the Dirichlet problem for the augmented k-Hessian equations in exterior domains have been proven.
