Using live feed as nutritious feed sources that can also contain natural pigments; is always recommended to strengthen skin pigment, improve growth performance and increase the general health of ornamental fish. This study was conducted to evaluate the effect of different levels of mealworms (Tenebrio molitor) larvae enriched with commercial probiotic, Protexin on some growth factors, survival rate, and skin color of Oscar (Astronotus ocellatus). First, the mealworms larvae were fed with 0 (control), 0.5, 1, 1.5 and 2% of a commercial Protexin probiotic along with wheat bran powder as the main feed resource for 14 days. Then, Oscar fish with an average weight of 3.0 ± 0.2 g and an initial length of 2.2 3 0.3 cm were randomly distributed into 15 glass aquariums with a density of 20 fish and were fed for 56 days with the enriched mealworms larvae with Protexin. Based on the results, weight gain (10.5 ± 0.23 g), body weight gain (7.54 ±0.31 g), daily growth rate (4.56 ± 0.34), specific growth rate (2.11 ±0.1), and longitudinal growth (3.5 ± 0.5 cm) in 2% treatment showed a significant difference compared to the control group and other treatments (P<0.05). The highest feed conversion ratio was obtained in control (1.25 ±0.17) and the lowest value was observed in 2% treatment (0.84 ±05). However, there was no significant difference in survival percentage between treatments receiving diets containing larvae enriched with probiotic, Protexin. The fish skin color according to L * and a * indices in the 2% treatment had a significant decrease compared to other treatments, especially the control treatment (P<0.05). The effect of different levels of mealworms larvae enriched with commercial probiotic, especially at the level of 2% feed on the growth indices and skin color of Oscar fish was evaluated as completely positive and significant.

 

Low back pain is one of the most common pains that about 80% of people experience in their lifetime. Millions of dollars are spent annually on the treatment of chronic low back pain, so proper and timely treatment is essential. This study aimed to determine the effect of McKenzie-based and Pneumatic Lumbar Unloading Orthosis on pain and disability in patients with chronic low back pain.

In this clinical trial, 27 patients with chronic low back pain who referred to the clinic of Shahid Adabian in Kermanshah in 2018 were included in the study by convenience sampling method and were randomly assigned to one of the study groups, which included the McKenzie-based group with Pneumatic Lumbar Unloading Orthosis, the McKenzie-based group, and the control group.

In both McKenzie-based and McKenzie-based groups with Pneumatic Lumbar Unloading Orthosis, pain and disability were significantly reduced. Although the intervention in the McKenzie-based group receiving Pneumatic Lumbar Unloading Orthosis resulted in a further reduction in pain and disability compared to the McKenzie-based group, the difference between the two groups in terms of pain relief was statistically significant (P< 0.05) but it was not significant in terms of the reduction of disability.

The Pneumatic Lumbar Unloading Orthosis with McKenzie-based reduced the pain and disability of people with chronic low back pain more effectively, so the simultaneous use of these therapeutic interventions in these people is recommended.

Knee orthosis is used in different cases and can be seen pistoning movement in all orthosis. The purpose of this study was to evaluate the effects of increasing mass knee brace and two kinds of silicon and polyethylene (PE) pad on pistoning movement during walking, on health subject.
Material and A total of 20 healthy volunteers, including 10 men and 10 women, with an average age of 24.65 years, participated in this study. Subjects used unloader knee brace with PE and silicon pad, with and without weights in four phases, and at each phase, they engaged in 10 minutes’ walk. Before and after each phase, using a video camera, the brace displacement on limb was measured with a marker. Finally, the pistoning movement of the orthosis on the knee was measured using the Kinovea software.
This study showed significant differences between the four tests (P The results showed that the use of silicone pads inside the brace construction, as well as lighter than knee brace, reduced migration, and increased comfort level. Moreover, compliance to knee braces was improved.
