Impact of foliar potassium fertilization on biochemical composition and antioxidant activity of fig (Ficus carica L.)
The metabolic processes involved in fig production are influenced by macro- and micronutrients supply to the
trees during the growing season. Potassium is an essential plant nutrient that influences growth and fruit quality.
In this study, the effect of foliar potassium sulphate (K2SO4) application on biochemical composition and antioxidant
activity of fig was assessed in cv. Bouhouli, a commonly cultivated cultivar in Djebba (Northwest of
Tunisia). Foliar potassium sulphate supply at 2% on Bouhouli trees were applied twice during the fruit growth.
Results exhibited that potassium fertilization induces a significant change in total phenolic, flavonoid contents
and radical scavenging activity in total fruit and achenes compared to the control. A strong correlation was
observed between antioxidant activity and different phenolic compounds. The total fruit and achenes methanol
extracts possess, respectively, the highest values of polyphenol by 29.3 and 25.1 mg GAE/g DW compared to the
control. Similarly, the flavonoids content was increased in methanol extracts, respectively, by 36 and 48%. HPLC
analyses revealed the influence of potassium on concentrations of phenolic compounds in fig sprayed with
K2SO4. Among the polyphenols, the chlorogenic acid, cyanidin 3-rutinoside and cyanidin 3,5-diglucoside contents
increased from 0.87 to 1.70 mg/g DW under potassium spray, whereas those compounds were not detected
in fig achenes. The present study provides clear evidence that potassium sulphate can be used to manipulate total
phenolic concentrations in fig with strong antioxidant potential that could be benefits to human health. Thus,
potassium sulphate application at 2% could improve nutritional and qualitative attributes of fig

Olive Wastes as a High-Potential by-Product: Variability of Their Phenolic Profiles, Antioxidant and Phytotoxic Properties
The global world olive oil industry produces large amounts of wastes and wastewaters. However, the disposal of these polluting by-products is a significant environmental problem owing to their high polyphenolic compounds. In order to learn possible ways of exploiting this waste, we investigated the phytochemical profiles, the phytotoxicity and the antioxidant activities of olive wastes (leaves, mill wastewater (OMWW) and mill solid waste (OMSW)). Leaf extracts exhibited the highest phytotoxic and antioxidant effects, which are mainly due to its phenolic content. The chromatographic profiles depicted eleven phenolic compounds belonging to secoiridoids, phenyl alcohols, phenolic acids, phenylethanoid glycoside, and flavonoids. Hydroxytyrosol and oleuropein were the main components in leaf methanol and OMWW extracts, respectively, exhibiting an amount of 13.05 and 4.39 mg/g DW. These results will help to demonstrate the possibility of utilizing olive wastes, particularly the leaf, as an inexpensive natural product, in food and agricultural applications.

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

INTRAVITREAL RANIBIZUMAB FOR CHOROIDAL NEOVASCULARIZATION IN ANGIOID STREAKS Four-Year Follow-up
Purpose:To analyze retrospectively the efficacy of intravitreal ranibizumab injections for the management of choroidal neovascularization in patients with angioid streaks over a long term.Methods:In this nonrandomized, double-center, retrospective, interventional case series, a consecutive series of patients affected with choroidal neovascularization associated with angioid streaks were treated with intravitreal ranibizumab injections (0.5 mg/0.05 mL). Best-corrected visual acuity, fundus photography, optical coherence tomography, and fluorescein angiography were examined before and after treatment. The primary endpoint was the percentage of eyes with stable or improved visual acuity at the end of follow-up (loss of less than 3 Early Treatment Diabetic Retinopathy Study lines). Secondary endpoints were the percentage of eyes with stable or decreased macular thickness on optical coherence tomography (less than a 10% increase in macular thickness) and the percentage of eyes with persistent leakage on fluorescein angiography at the last observation carried forward.Results:Thirty-five eyes of 27 patients were treated with repeated intravitreal ranibizumab injections (mean of 9.9 7.2 injections, range 2-26) for a mean of 48.6 +/- 17.1 months (range 8-66). At the end of follow-up, best-corrected visual acuity was stabilized or improved in 22 of 35 eyes (62.9%). Macular thickness had stabilized or decreased in 16 of 35 eyes (45.7%). At the last follow-up examination, on fluorescein angiography, no further leakage was observed in 27 of 35 eyes (77.1%).Conclusion:In this large series of patients with choroidal neovascularization associated with angioid streaks followed for 4 years, ranibizumab injections allowed stabilization of best-corrected visual acuity in most eyes. Ranibizumab appear as an effective therapeutic option in CNV associated with angioid streaks over long time
The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
Answering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
