A metal-free 16-membered N4-donor [1 + 1] Schiff-base macrocycle was isolated as HL(Pr)·2acid, by 1 : 1 condensation of diphenylamine-2,2'-dicarboxaldehyde (1), dipropylene triamine and an excess of either acetic or formic acid, or as HL(Pr)·(tosylic acid) when just one equivalent of tosylic acid was employed. Interestingly, the acid-free synthesis employed for the 14-membered analogue HL(Et) f...

The importance of the progesterone receptor (PR) in female reproductive and mammary gland biology is well recognized; however, the coregulators selectively enlisted by PR have yet to be comprehensively defined in vivo. To evaluate the involvement of steroid receptor coactivator (SRC)/p160 family members in these physiological systems, a mouse model (PRCre/+SRC-2flox/flox) was generated in which...

Human progesterone receptor (PR) contains a motif that interacts with the SH3 domain of Src and mediates rapid activation of Src and downstream MAPK (Erk-1/-2) without relying on the transcriptional activity of the receptor. Here we investigated the role and intracellular location of this nontranscriptional activity of PR. Progestin activation of Src/MAPK occurred outside the nucleus with the B...

1 Progesterone receptors (PR) are critical mediators of mammary gland development and 2 contribute to breast cancer progression. Progestin-induced rapid activation of 3 cytoplasmic protein kinases leads to selective regulation of growth-promoting genes by 4 phospho-PR species. Herein, we show that phosphorylation of PR Ser81 is ck25 dependent and progestin-regulated in intact cells, but also oc...

This study was done to evaluate the frequency, intensity, and specificity of a positive pathergy reaction (PR) in Behcet's disease (BD) patients, to clarify an association between the PR and the clinical features or disease severity, and to assess whether patients with pustule formation at the venous puncture site (PFVPS) without positive PR could be regarded as a positive reaction. The PR was ...

Male breast cancer is a rare disease with an increasing trend. Due to limited information especially about the genetic basis of the disease in Iran and the lower age of its onset, the disease requires more attention. The aim of this study was to screen the male patients with breast cancer for BRCA mutations as well as tissue markers of estrogen receptor (ER), progesterone receptor (PR), human e...

We report on a Ag5 coordination polymer and discrete Ag8 and Ag10 dithiophosphate clusters. The cluster formation and structures were affected by the stoichiometric control of the M : L molar ratios used. The cluster [Ag5{S2P(O(i)Pr)2}4]n(PF6)n, , is a monomeric unit within a coordination polymer formed through the reaction between [Ag(CH3CN)4]PF6 and the dithiophosphate ligand, [S2P(O(i)Pr)2](...

Consider a set of r convex d-polytopes P1, P2, . . . , Pr, where d ≥ 3 and r ≥ 2, and let ni be the number of vertices of Pi, 1 ≤ i ≤ r. It has been shown by Fukuda and Weibel [4] that the number of k-faces of the Minkowski sum, P1 + P2 + · · · + Pr, is bounded from above by Φk+r(n1, n2, . . . , nr), where Φl(n1, n2, . . . , nr) = ∑ 1≤si≤ni s1+...+sr=l ∏ r i=1 ( ni si ) , l ≥ r.
