[Purpose] The objective of this study was to determine the effect of pulsed high intensity laser therapy on delayed caesarean section healing in diabetic women. [Subjects and Methods] This study was conducted on forty diabetic women with delayed caesarean wound healing, ranging in age from 28 to 38 years. They were randomly assigned into two groups; the group I (n=20) received pulsed high intensity laser therapy for 6-weeks, 3 times per week plus standard medical treatment for treatment of diabetes and caesarean wound patients, the group II (n=20) received sham laser treatment for 6 weeks, 3 times per week plus standard medical treatment for treatment of diabetes and caesarean wound patients. The wound size and appearance in all participants were measured by the tracing method and pressure sore status tool before and after the 6-week treatment. [Results] Pulsed high intensity laser therapy produced a significant difference in wound size and appearance in comparison to the sham laser treatment in diabetic women with delayed caesarean wound healing. [Conclusion] Pulsed high intensity laser therapy is effective in the treatment of delayed caesarean section healing in diabetic women.

A new two-dimensional graphical representation of protein sequences is introduced. Twenty concentric evenly spaced circles divided by n radial lines into equal divisions are selected to represent any protein sequence of length n. Each circle represents one of the different 20 amino acids, and each radial line represents a single amino acid of the protein sequence. An efficient numerical method based on the graph is proposed to measure the similarity between two protein sequences. To prove the accuracy of our approach, the method is applied to NADH dehydrogenase subunit 5 (ND5) proteins of nine different species and 24 transferrin sequences from vertebrates. High values of correlation coefficient between our results and the results of ClustalW are obtained (approximately perfect correlations). These values are higher than the values obtained in many other related works.

Aim: To assess the efficacy of 12 sessions with 905 nm the infra-red laser in patients with acne vulgaris. Materials and Methods: Study design was a randomized controlled study as forty patients with facial acne were randomly assigned into 2 equal groups; study and control groups. Study Group (A): includes 20 patients received infrared laser with 905nm wavelength and intensity of 6J/cm², while control Group (B): includes 20 patients received shame treatment. Before and after treatment, all patients were assessed by comparative acne severity scale. In addition, facial photographs were taken using a digital camera. Photographs were taken using the same manner at all measurement times. Results: There was a highly significant difference between pre and post-treatment phases within laser group (A) as the p-value = (0.0001), also there was a highly significant difference between both groups at post-treatment phase as the p-value = (0.0001).Conclusion: Twelve sessions with 905 nm infrared laser provide a satisfying improving effect on acne vulgaris patient.

Objectives: To investigate the effect of electrical stimulation of different anatomical variations of sacral surface on early recovery of urinary continence after radical prostatectomy. Methods: Twenty of 53 consecutive patients who underwent prostatectomy by a single surgeon were enrolled in this study. Ten patients were prospectively randomized to two groups; five patients in Sacral foramena stimulation group received postoperative surface electrical stimulation of sacral foramina area while five patients in control group did not received any electrical stimulation. Selection of remaining ten patients depended on sacral hiatus anatomical variations, assessed by plan X-rays. Of the ten patients, five patients with sacral hiatus subtotals were grouped under SHS1 while 5 patients with sacral hiatus totals were grouped as SHS2. Electrical stimulation for each group began 7 days after catheter removal, thrice a week for 8 weeks. Each of the 24 treatment sessions for each group composed of 20 minutes for sacral electrical stimulation. Continence was evaluated at baseline, 4 and 8 weeks using the 24-hour pad test and according to the incontinence section of the International Continence Society questionnaire. Results: After 2 weeks of treatment, the mean leakage weight was comparable between SFS group and SHS1 group while it was significantly lowered in SHS2 as compared to SFS and SHS1 groups. Comparing mean leakage weight at 8 weeks revealed further significant reduction in SHS2 group than in SFS and SHS1 groups. Moreover, percentage of continent patients was highest in SHS2 2group after 8 weeks of treatment followed by SHS1, SFS and control respectively. Conclusions: Electrical stimulation of sacral hiatus surface area may provide better stimulation for sacral nerve than sacral foramena surface area and appears to be effective treatment for early recovery of urinary continence after radical prostatectomy.
