DESIGN Prospective, randomized, controlled trial. SETTING Tertiary care University Hospital. PATIENT(S) Two hundred thirty-nine women who underwent laparoscopic excision of ovarian endometriomas. INTERVENTION(...

In this paper, we investigate domination number as well as signed domination numbers of Cay(G : S) for all cyclic group G of order n, where n in {p^m; pq} and S = { a^i : i in B(1; n)}. We also introduce some families of connected regular graphs gamma such that gamma_S(Gamma) in {2,3,4,5 }.

A cyclic sum S(x) ■ T.x¡/(xj+i + x, + 2) 's formed with the N components of a vector x, where xN+l « JCj, xN+2 =• x2, and where all denominators are positive and all numerators are nonnegative. It is known that there exist vectors x for which S(x) < N/2 if N > 14 and even, and if N > 25. It has been proved that the inequality S(\) > N/2 holds for N ^ 12. Although it has been conjectured repeate...

This paper presents a 14-bit cyclic-pipelined Analog to digital converter (ADC) running at 1 MS/s. The architecture is based on a 1.5-bit per stage structure utilizing digital correction for each stage. The ADC consists of two 1.5-bit stages, one shift register delay line, and digital error correction logic. Inside each 1.5-bit stage, there is one gain-boosting op-amp and two comparators. The A...

Continuous perfusion of rat hearts with concentrations of forskolin between 0.1 and 12 microM resulted in transient increases in tension after 45 s, followed by a return to the control value after 5 min. In contrast, the content of cyclic AMP increased linearly with time over this period, reaching values up to 35 times control after 5 min. Increases in contractile force, intracellular cyclic AM...

A new cyclic diarylheptanoid namely alnuheptanoid B (3), along with four known cyclic diarylheptanoids: myricanone (1), (+)-S-myricanol (2), myricanone 5-O--D-glucopyranoside (4), and (+)-S-myricanol 5-O--D-glucopyranoside (5) were isolated from the EtOAc fraction of Alnus japonica Steud (family: Betulaceae) stem bark. Their structures were established by different spectroscopic analyses, as ...
