Abstract

Silver nanoparticles (AgNPs) are commonly used in consumer products for their antibacterial activity. Silver nanoparticles may adversely influence organisms when released into the environment. The present study investigated the effect of AgNPs on the growth, morphology, and physiology of the aquatic plant duckweed ( Spirodela polyrhiza). The toxicity of AgNPs and AgNO3 was also compared. The results showed that silver content in plant tissue increased significantly with higher concentrations of AgNPs and AgNO3. Silver nanoparticles and AgNO3 significantly decreased plant biomass, caused colonies of S. polyrhiza to disintegrate, and also resulted in root abscission. Physiological analysis showed that AgNPs and AgNO3 significantly decreased plant tissue nitrate-nitrogen content, chlorophyll a (Chl a) content, chlorophyll a/ b (Chl a/ b), and chlorophyll fluorescence (Fv/Fm). Changes in soluble carbohydrate and proline content were also detected after both AgNO3 and AgNPs treatment. However, after 192 h of recovery, total chlorophyll content increased, and Fv/Fm returned to control level. Median effective concentration (EC50) values for Chl a and phosphate content showed that AgNO3 was more toxic than AgNPs (EC50 values: 16.10 ± 0.75 vs 7.96 ± 0.81 and 17.33 ± 4.47 vs 9.14 ± 2.89 mg Ag L−1, respectively), whereas dry-weight EC50 values showed that AgNPs were more toxic than AgNO3 (13.39 ± 1.06 vs 17.67 ± 1.16 mg Ag L−1).

36. Systemic Apophysomyces elegans after Trauma: Case Report and Literature Review

Author

Wang, Jue, Harvey, Charles M., Calhoun, Jason H., Yin, Li-Yan, and Mader, Jon T.

Abstract

We present a case of systemic fungal infection caused by Apophysomyces elegans in a 50-year-old patient who developed a progressive skin lesion after a motor vehicle crash. Histopathological and mycological examination of the surgical sample showed non-septated hyphae characteristic of mucoraceous fungi. Despite extensive surgical debridement, and parenteral administration of amphotericin B, the patient died of multi-organ failure. Autopsy findings suggested systemic involvement. The fungi recovered from culture had non-apophyseal and globose sporangi, and branched sporaniophores and was identified as Apophyso-myces elegans.

Abstract

Curcuma wenyujin, as one of the eight Daodi-herbs in Zhejiang province, is widely used. It has the effects of eliminating stasis and dissipating mass, moving Qi and activating blood, and clearing heart and relieving depression. Modern studies have shown that it has anti-tumor, anti-inflammatory, anti-oxidation, anti-thrombus and liver-protecting effects and mainly contains sesquiterpenoids, monoterpenoids, diterpenoids, and curcumins. This paper reviews the research progress in the chemical constituents and pharmacological effects of C. wenyujin in the last decade, discusses the modern clinical applications combined with the traditional efficacy, and predicts its quality markers(Q-markers) from plant consanguinity, medicinal properties, efficacy, processing and measurability of chemical components based on the theory of Q-markers, so as to provide a reference for the establishment of a scientific quality evaluation system and the research and application of this herb in the future.
