leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. leptin and itsreceptor (ob-r) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. the goal of this study was determination of the presence of leptin receptor mrna in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...

background: the role of retinoblastoma (rb) protein in cell cycle regulation prompted us to take up this study with the aim of assessing its role in the progression of oral cancer and to correlate with various clinicopathological parameters, including habits such as smoking, paan chewing, and alcoholism. materials and methods: this observational study included surgical specimens from 10 apparen...

Prove that the θ scheme (I − θkD + D −)v n+1 j = (I + (1 − θ)kD + D −)v n j , j = 0, 1,. .. , N, 0 ≤ θ ≤ 1 (1) is unconditionally stable for θ ≥ 1 2. In order to find the necessary conditions for stability, we begin by making the ansatz v n j = 1 √ 2π e iωx j ˆ v n (ω), where the solution is composed of a single Fourier component. Substituting this expression into Equation 1, we obtain the foll...
