Recently, Eisenbrand, Pach, Rothvoß, and Sopher studied the function M(m, n), which is the largest cardinality of a convexly independent subset of the Minkowski sum of some planar point sets P and Q with |P | = m and |Q| = n. They proved that M(m, n) = O(m2/3n2/3+m+n), and asked whether a superlinear lower bound exists for M(n, n). In this note, we show that their upper bound is the best possib...

the role of zinc (zn) in enhancing defense capacity of several plants against salinity has been demonstrated but there is limited information on the impact of zn nutrition on alleviating salinity-induced oxidative damage in olive. one-year-old seedlings of two varieties of olive (olea europaea l. cvs. frontoio and conservolea) supplied with three zn levels (0, 1 and 5 mm in the form of znso4.7h...

Pd-catalyzed allylic relay Suzuki cross-coupling reactions of secondary alkyl tosylates, featuring a sterically-hindered oxidative addition and precise control of β-hydride elimination, are reported. The identification of a linear free energy relationship between the relative rates of substrate consumption and the electronic nature of the substrate alkene suggests that the oxidative addition re...

background: leptin and its receptor are present in spermatozoa; however, the role of leptin in sperm function is still controversial. our present study aimed at demonstrating the effect of cryopreservation on sperm dna fragmentation (dnaf) and investigating the possible effects of sperm capacitation techniques and leptin in vitro incubation on frozen-thawed sperm dnaf and oxidative stress. meth...

o bjective : increased levels of oxidative stress markers in periodontitis have been reported by recent studies. malondialdehyde (mda) and superoxide dismutase (sod) are both in- creased during oxidative stress. the aim of this study was to detect and measure the level of oxidative stress markers in peri-implant crevicular fluid (picf). their correlation with peri-implant clinical parameters wa...

PURPOSE To characterize the molecular basis of oxidative stress-induced death, a process that has been implicated in several chronic eye diseases, in RGC-5 cells, an immortalized retinal ganglion cell (RGC) line. METHODS The responses of RGC-5 cells to oxidative stress induced by three different treatments--glutathione depletion, tert-butyl peroxide addition, and hydrogen peroxide addition--w...
