Nine sesterterpenes 1-9 have been isolated from a Dictyoceratid sponge, Strepsichordaia lendenfeldi, collected on the Great Barrier Reef, Australia. Seven of these compounds are new, one [4] had been reported previously as a semisynthetic product, and one [5] had been isolated previously from Carteriospongia foliascens. Unambiguous 13C- and 1H-nmr assignments have been made for 1 based on extensive 1D and 2D high field nmr experiments, which enabled 13C-nmr assignments to be made for 2-9. Significant growth inhibitory effects with tested cancer cell lines are reported for compounds 1-8.

DFI scores did not provide independent information regarding fertilization, embryo quality, or pregnancy for infertile patients who received IVF or ICSI, but were consistent with semen analysis for infertile couples, regardless of IVF or ICSI outcome.

Home-based multi-sensor Internet of Things, as a typical application of Internet of Things, interconnects a variety of intelligent sensor devices and appliances to provide intelligent services to individuals in a ubiquitous way. As families become more and more intelligent, complex, and technology-dependent, there is less and less need for human intervention. Recently, many security attacks have shown that Internet home-based Internet of Things have become a vulnerable target, leading to personal privacy problems. For example, eavesdroppers can acquire the identity of specific devices or sensors through public channels, which is not secure, to infer individual public life in the home area network. Authentication is the essential portion of many secure systems processing of verifying and declaring identity. Before providing confidential information, home-based-Internet of Things service authenticates users and devices. The communication and processing capabilities of intelligent devices are limited. Therefore, in home-based Internet of Things, lightweight authentication and key agreement technology are very important to resist known attacks. This article proposes an anonymous authenticated key agreement protocol using pairing-based cryptography. The protocol proposed in this article provides lightweight computation and ensures the security of communication between home-based multi-sensor Internet of Things network and Internet network.
