Porous materials have many structural advantages for energy storage and conversion devices such as rechargeable batteries, supercapacitors, and fuel cells. When applied as a host material in lithium-sulfur batteries, porous silica materials with a pomegranate-like architecture can not only act as a buffer matrix for accommodating a large volume change of sulfur, but also suppress the polysulfide shuttle effect. The porous silica/sulfur composite cathodes exhibit excellent electrochemical performances including a high specific capacity of 1450 mA h g-1, a reversible capacity of 82...

FLOWERING LOCUS T (FT) and TERMINAL FLOWER1/CENTRORADIALIS (TFL1/CEN) are the key regulators of flowering time in plants with FT promoting flowering and TFL1 repressing flowering. TFL1 also controls floral meristem identity and its maintenance. In this study we have characterized two pomegranate (Punica granatum L.) TFL1/CEN-like genes designated as PgTFL1 and PgCENa. The expression of PgTFL1 and PgCENa fluctuated through alternate pruning and flowering cycles, being highly expressed during the vegetative phase (immediately after pruning) and decreasing gradually in the months thereafter such that their lowest levels, especially for PgCENa coincided with the flowering phase...

Leishmania species are parasites that multiply within phagocytes and cause several clinical diseases characterized by single or multiple ulcerations. One of the complications that can induce tissue damage and the resulting scars is caused by secondary bacterial infections. Studies to find new, effective, and safe oral drugs for treating leishmaniasis are being conducted since several decades, owing to the problems associated with the use of antimonials available. Previously, the antiparasitic and antioxidant properties of Punica granatum (pomegranate, P...

Punicalagin (PUN), a component derived from pomegranate, is well known for its anticancer activity. Our previous work revealed that PUN induces autophagic cell death in papillary thyroid carcinoma cells. We hypothesized that PUN triggers DNA damage associated with cell death because DNA damage was reported as an inducer of autophagy. Our results showed that PUN treatment caused DNA breaks as evidenced by the significant enhancement in the phosphorylation of H2A.X. However, reactive oxygen species and DNA conformational alteration, 2 common inducing factors in DNA damage, were not involved in PUN-induced DNA damage...
