Why did the European Union （EU） conclude an Association Agreement （A.A）, rather than a free-trade agreement with Central American （CA） countries in 2010？ A CA-EU AA content analysis within the broader EU policy approach towards Latin America suggests it to be （1） the only feasible option for each side at a time of increasing commercial flux; （2） mutually attractive against globalizing threats, thus converting an institutional innovation into a double-edged instrument; and （3） illustrative of the subtle but significant shift of farm-protection demands from endogenous dynamics to exogenous. They carry important implications：（1） empirically： weak CA-EU linkages further dilute West Europe＇s broader Latin ambitions; （2） theoretically： AA analyses better reflect trading realities than pure regional economic integration theories, suggesting the corrosive impact of globalizing forces on regional pursuits; and （3） historically： the continued role of the farm jinx in trade.

AIM: To investigate the effectiveness of combinationtherapy with transzonular triamcinolone-moxifloxacin andconventional perioperative drops in reducing postoperativecomplications of cataract surgery. METHODS: Electronic medical records of cataractsurgery patients (single surgeon) were reviewed fromJanuary 2018 to September 2021. The rate of postoperativecomplications including prolonged and/or recurrentpostoperative inflammation, endophthalmitis, cystoid macularedema (CME), and intraocular pressure (IOP) was comparedbetween the patients receiving combinative therapy andpatients receiving drops only. RESULTS: Totally 596 patients and 1057 eyes(Combinative-Therapy group 493 and Drop-Only group 564)were included in this study. Using combination therapyreduced the relative risk of postoperative inflammationby 26.9% (16.6% Combinative-Therapy vs 22.7% Drop-Only, P=0.013). The incidence of endophthalmitis was 0in Combinative-Therapy group vs 0.5% in Drop-Only group(relative risk reduction 100%), although not statisticallysignificant (P=0.10). The incidence of severe IOP spikeswas not significantly different between Combinative-Therapy (2.4%) and Drop-Only (1.6%) groups (P=0.33).The relative risk of postoperative CME was 51.4% less inthree months follow up visit in Combinative-Therapy group,although not statistically significant (P=0.07). The visualoutcome 1-month postop. (best corrected visual acuity) wassignificantly better in Combinative-Therapy (logMAR 0.10)compared to Drop-Only (logMAR 0.14) groups (P=0.02) whilethe baseline visual acuity was not significantly different. CONCLUSION: The combinative approach oftranszonular triamcinolone-moxifloxacin plus perioperativeeyedrops is an effective method to minimize postoperativeinflammation, with better visual outcomes. It couldpotentially reduce the risk of postoperative endophthalmitisand CME (near-significant P-values;larger studies couldanalyze better considering low incidence).

Desulphurization of model and real oil samples was investigated using performic acid as oxidant assisted by air as co-oxidant. The catalysts used were Mo-oxide supported on ZSM-5 zeolite, which was synthesized in the laboratory and characterized by FT-IR, XRD, SEM and SSA analysis. In case of model oil, the optimum condition determined for complete oxidation of all the model compounds including thiophene, DBT and 4,6-DMDBT were;60?C, 60 min, ambient pressure and air flow rate of 100 mL/min. The oxidation reactivity decreased from 4,6-DMDBT to DBT and thiophene, which was found to follow pseudo first order kinetics. The real oil sample used in the study included untreated naphtha (NP), light gas oil (LGO), heavy gas oil (HGO) and Athabasca bitumen (Bit.). In case of NP and LGO the sulfur removal of above 78% was attained whereas in case of HGO and Bit. samples about 60% of desulfurization was achieved.
