Low back pain is a common disease. A common cause of this problem is a herniated disc in the lumbar spine. Lumbar disc herniation represents the displacement of the disc (annular fibrosis or medullary nuclei). While most cases, the pain will disappear in a few days to a few weeks; however, it can last for three months or more. Detection and diagnosis are the two most important tasks in a computer-aided diagnostic system. In this article, we use images taken from the results of the MRI imaging of the patient. Through the use of image inversion to highlight the position of degenerative discs. This result wishes to provide a simple and inexpensive diagnostic image processing method to help doctors quickly determine the degree of disc herniation, the status of lumbar discs, they can give the appropriate treatment to the patient.

Applying laser technology to the growth of plants to limit the use of chemical fertilizers is an interesting topic in agriculture. The main idea is to preserve the environment, ensuring product quality while still achieving high productivity, we decided to carry out this research project, to investigate the effect of the low-level laser (the wavelengths 532nm, 850nm, and 940nm) on stems and leaf development. It is expected that with these research results, the implementation method will be widely disseminated in the high agricultural sector, coming closer to farmers. Moreover, the results of the analysis of the composition of bitter melon stems and leaves will be applied in medical treatment (such as diabetes, wound treatment, anti-oxidation, anti-bacteria ...)

This research aims to evaluate the effect of low-level laser therapy (LLLT) on the healing of the burn for the mouse. Four mouses are divided into 4 groups. Group 1, 2, 3 are irradiated by a wavelength of 532nm, 850nm, and 940nm. Group 4 is a control group that has a natural recovery. Low-level laser therapy makes the regenerative process, healing occurs faster, and rehabilitation of mouse activity during treatment.

This experimental study aimed to evaluate if the effect simultaneously wavelengths of 780 nm and 940 nm enhances bone regeneration of the broken bone. Experiments on pets: 14 dogs, were randomly divided into 2 groups: group I (low-level laser therapy) and group II (control). The results showed that dogs in group I had better bone regeneration and bone marrow formation than the control group. Then, we treated 25 patients with different fracture levels. They agreed to enjoy our method. After treatment, the fracture is no longer visible on X-ray film. The majority of patients after treatment only feel no pain or mild pain. This suggests that osteoblasts are positively affected when projected by low-level laser. It is very practical for the treatment of older patients because osteoblasts grow slowly than osteoclast.
