Th. stress-concentration effect of fiber-end geometries on th. propagating stress waves in composite models was investigated by th. dynamic ph.toelastic meth.d. Aluminum fibers with.rectangular, semicircular, V-and wedge-sh.pe ends simulating such.materials as reinforced concrete and fiber-bundle-reinforced composites were cast in epoxy resin to form th. models. Impact was applide by th. bullet of a rifle. Th. effects of th. reinforced rod or fiber-bundle ends on th. dynamic birefringent patterns were analyzed by comparing th. fringe patterns at th. same locations in a plain model of identical Contour under th. same loading conditions.

For a long time since th.ir discovery by Ch.istian de Duve in th. 1950s,lysosomes h.ve been referred to almost exclusively as passive garbage bags;th. endpoint in th. degradation of intra-and extracellular *** catabolic function of lysosomes is accomplish.d by an array of more th.n 60 acid h.drolases,wh.ch.togeth.r break down a wide variety of biological macromolecules,including proteins,lipids,carboh.drates,and nucleic acids,for reutilization in th. metabolic processes of th. *** th.ir optimal function,th.se enzymes require an acidic intraluminal ph.of~4.5,wh.ch.is maintained by th. joint action of a proton pump,th. vacuolar h.-ATPase,and several ion ch.nnels embedded in th. lysosomal limiting membrane.

Th. purpose of th.s study was to compare adipokines’ levels between women with.and with.ut preeclampsia based on maternal body mass index (BMI). Study design: Th.s was a cross-sectional study among th.rd-trimester pregnancies with.preeclampsia (pih) compared with.normotensive controls. Serum levels of adiponectin, leptin, and resistin were measured before delivery by radioimmunoassay or enzyme-linked immunosorbent assay (ELISA). Results: Th. study included 22 normotensive and 77 pih women. Leptin levels increased with.maternal BMI. In patients with.severe preeclampsia, overweigh., and obese women h.d increased leptin levels (33.4 ± 14.8 vs 23.0 ± 10.8 ng/mL respectively, P = .02), and decreased adiponectin levels (8.4 ± 5.3 vs 12.6 ± 6.0 ng/mL, P = .03) compared with.normal weigh. women. In women with.BMI h.preeclampsia compared with.controls (11.5 ± 5.6 vs 9.6 ± 4.6 and 7.0 ± 3.2 ng/mL, respectively, P = .005). Th.re was no association between resistin levels and preeclampsia or maternal BMI. Conclusion: Women with.severe preeclampsia and BMI ≥ 25 kg/m2 h.ve decreased adiponectin and increased leptin levels, wh.le normal weigh. women with.preeclampsia h.ve increased adiponectin levels.
