Anisotropic materials with abnormal Poisson's ratios and acoustic velocities.

Isotropic materials are required to adhere to various mechanical principles due to their limited thermal stability. For instance, it is essential for Poisson's ratio to be within the range of -1 to 0.5, and the longitudinal wave velocity must exceed the transverse wave velocity.

Clinical Effect of Vitamin E Combined with Recombinant Human Epidermal Growth Factor on the Recurrent Oral Ulcer and Effects of Serum Superoxide Dismutase, IL-10, and TNF-α.

Objective: To examine the therapeutic effects of vitamin E combined with recombinant human epidermal growth factor on recurrent oral ulcers as well as on the levels of serum superoxide dismutase (SOD), interleukin-10 (IL-10), and tumor necrosis factor- (TNF-α), to provide evidence to facilitate medical management.

Method: From June 2021 to May 2022, 84 patients with recurrent oral ulcers assessed and treated in our hospital were assigned to the control group and observation group with 42 cases in each group. Vitamin E was administered to the control group, while recombinant human epidermal growth factor and vitamin E were administered to the observation group.

Ophiopogonin B induces reactive oxygen species‑dependent apoptosis through the Hippo pathway in nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is a common malignant tumor in South China and is characterized by a high death rate. Ophiopogonin B (OP‑B) is a bioactive component of Radix , which is frequently used in traditional Chinese medicine to treat cancer. The present study aimed to examine the anti‑cancer properties of OP‑B on NPC cells.
