Researchers are continuously exploring the potential use of microwave imaging in early detection breast cancer. The technique offers a promising alternative to mammography, standard clinical procedure today. contrast dielectric properties between normal and cancerous tissues makes viable for detecting Experimental results presented this paper that demonstrate cancer using microwaves operating a...

The extracellular matrix of stylar transmitting tissues of many angiosperms is enriched in secretory materials that are believed to be important for interactions with pollen tubes. We have previously characterized two related cDNAs (TTS-1 and TTS-2) for stylar transmitting tissue-specific proline-rich proteins (TTS proteins) from Nicotiana tabacum. We show here that TTS proteins are highly glyc...

Pollen tubes elongate directionally in the extracellular matrix of pistil tissues to transport the male gametes from the apically located stigma to the basally located ovary for fertilization. The molecular mechanisms underlying directional pollen tube growth in the pistil are poorly understood. We have purified a glycoprotein, TTS, from tobacco stylar transmitting tissue, which supports pollen...
