This study was a parallel-group, double-blind, stratified, randomized controlled animal trial with 1:1 allocation ratio. Endometriosis was induced experimentally in 23 mature, nulligravid, female Sprague-Dawley rats, weighing approximately 200 g and aged 2 months. A checkpoint surgery was performed 6 weeks later. Then, the rats were randomly allocated into the thalidomide (22 mg/day p.o.) and control (0.5 mL saline 0.9%/day p.o.) groups of nine. After 6 weeks, they were killed. Before each laparotomy, blood for leukocyte and lymphocyte counts and during them, implants for histopathology and peritoneal fluid for interleukin (IL)-6, tumor necrosis factor-α and vascular endothelial growth factor (VEGF)-A concentrations (by enzyme-linked immunoassay) were collected. Allocation and stratified randomization were done using a computer, based on the obtained histopathology scores of the implants of the checkpoint surgery. The histopathology scores (the main outcome measure) were 2.00 ± 1.55 versus 0.44 ± 1.01 (P = 0.035). The comparisons of after-treatment counts of leukocytes, lymphocytes, VEGF-A and IL-6 between the two groups were statistically significant. The results of this study are in favor of therapeutic implication of thalidomide in experimental endometriosis in rats. This is the first time thalidomide has been evaluated on endometriosis in an animal model.

Research paper thumbnail of Micro-bending based optical band-pass filter and its application in S-band Thulium-doped fiber amplifier

The proposed filter leverages the bending loss of higher order modes at shorter wavelengths. At longer wavelengths, the filter increases fiber's bending loss as the fundamental mode 'tail' is leak out from the cladding. The combination of wavelength dependent loss at longer and shorter wavelength gives rise to the optical band-pass filter characteristic inside the fiber. The simulated spectral response of the filter is found to be in good agreement with the experimental results. Subsequently, the proposed optical band-pass filter is applied in Thulium-doped fiber amplifiers (TDFA) system for gain and noise figure enhancements. The filter functions to suppress both the amplified spontaneous emission (ASE) at 800 nm and 1800 nm wavelength regions and thus improves both gain and noise figure performances in Sband region. By bending of the gain medium, gain and noise figure of the TDFA are improved by about 2 dB and 0.5 dB respectively, within a wavelength region from 1440 and 1500 nm when the 1050 nm pump power is fixed at 250 mW.

Research paper thumbnail of Effect of clomiphene citrate on endometrium thickness and echogenic patterns

Method: In this experimental prospective study, CC was given to 31 women with unexplained infertility. Thickness and echo patterns of the endometrium, as well as estradiol (E2) and progesterone (P) levels, were compared in women taking CC and in control patients during both the late proliferative and midsecretory phases of the menstrual cycle. Results: Endometrial thickness was significantly thinner in women taking CC (P-0.03) than in controls during the late proliferative phase but there was no significant difference during the midsecretory phase. The endometrial echogenic patterns of women taking CC who had conceived revealed endometrial thicknesses of grade III and grade IV on midsecretory days, but these findings were not significantly different from those of women who had not conceived (Ps0.3). Serum E2 level was higher in women taking CC than in the controls on both late proliferative and midsecretory days (P-0.05). Conclusion: CC affects endometrium thickness on late proliferative days but not on midsecretory days, and does not alter the echogenic pattern of the endometrium.
