We used seedlings of the two subspecies originated from wild plants from the natural habitats in Sicily and cultivated in the Botanical Garden of Rome. Leaf morphological and physiological traits and growth dynamic were analyzed as well as the response to an imposed water stress experiment. The results underlined a higher relative growth rate in plant height (RGRH, cm·cm-1·d-1) in B. rupestris subsp. rupestris also attested by the highest plant height (H, cm), leaf area (LA, cm2), specific leaf area (SLA, cm·g-1), total leaf area per plant (TLA, cm2) and total plant dry mass (PDM, g plant-1). Moreover, the significantly highest net photosynthetic rates (A, μmol CO2 m-2·s-1) during the study period of this subspecies was related to the high Chlorophyll content (Chl, SPAD units). B. rupestris subsp. rupestris was also the most tolerant subspecies to imposed water stress showing the highest relative water content (RWC, %), A and water use efficiency (WUE, μmol·mmol-1).展开更多

Patients(n = 45) in the treatment group were provided the standard endocrine therapy along with oral Huikangling(0.4 g/tablet, 0.4 g × 3/time, 3 times/day, 12 weeks). Patients(n = 42) in the control group were only provided the standard therapy. After 4 and 12 weeks, CTCs in the blood were detected by flow cytometry.Results After 4 weeks of oral Huikangling treatment, CTCs were detected in 18(40%) and 29(69%) patients in the treatment and control groups, respectively; the difference was statistically significant(χ2 = 8.49, P < 0.05). After 12 weeks, CTCs were detected in 7(15.6%) and 17(44.7%) patients in the treatment and control groups, respectively; the difference was statistically significant(χ2 = 5.68, P < 0.05). Follow-up evaluation revealed two patients with lung metastasis and one patient with bone metastasis in the control group; one patient showed lateral neck lymph node metastasis without local recurrence in the treatment group.Conclusion Huikangling treatment reduces the number of CTC-positive DTC cases; however, further studies are needed to elucidate the underlying mechanisms.展开更多

This study evaluated the effects of ribavirin at different concentrations(15 and 25 μg mL^(–1);R15 and R25, respectively), thermotherapy(37°C;T), and the combination of ribavirin and thermotherapy(R15+T and R25+T) on eliminating viruses from grapevine plants in vitro. Both R15 and R25 had phytotoxic effects and weakened plant growth. Thermotherapy positively affected the growth of grapevine plants. Plant height was significantly greater in T, R15+T, and R25+T than in CK, R15 and R25. The proportion of dead plants after T, R15+T, and R25+T was 51.4, 11.4, and 8.6%, respectively. The survival rates of regenerated plants after all treatments were >68.0%. Ribavirin concentration and treatment time were related to the regeneration of shoot tips and elimination efficiencies of the two viruses. The survival rates of plants after R15+T for 30, 40, and 50 days were 97.3, 90.7, and 74.4%, respectively. The elimination rates of GRSPaV from plants in the three time quantum were 55.6, 84.6, and 93.8%, respectively. The elimination rate of GFkV was 23.9% higher in R25(35/44) than in R15(25/45), and that of GRSPaV was 7.0% higher in R25 than in R15. The combination of thermotherapy and chemotherapy was found to have a positive effect on the eradication of GFkV and GRSPaV, and R25+T for 50 days was able to completely eliminate the two viruses from in vitro grapevines.展开更多
