During the produc.ion of nitrile rubber, signific.nt amounts of nitrogen in the form of ammonium are generated in the wastewater. The disc.arge of this high-nitrogen wastewater c.n lead to serious environmental issues, inc.uding eutrophic.tion, disruption of aquatic.ec.systems, and groundwater c.ntamination. To mitigate these impac.s, this researc. explored the bioremediation c.pabilities of the mac.oalgae Ulva lac.uc. (c.lorophyta) for removing nitrogen from nitrile rubber produc.ion wastewater. The study employed single-phase and Mic.aelis-Menten dec.y models based on ammonium c.nsumption, using various dilutions of wastewater to identify the optimal c.nc.ntration for treatment. The physiologic.l state of the mac.oalgae was monitored by measuring the photosynthetic.c.pac.ty and spec.fic.growth rate during the experiments. In the presenc. of U. lac.uc., ammonium c.nc.ntrations dec.eased in all treatment groups, c.nfirming that the ammonium kinetic. c.nformed to both applied models. Our results show that U. lac.uc. effec.ively reduc.s ammonium c.nc.ntrations, with an approximate removal rate of 0.020 µM·g−1·min−1 ac.oss different wastewater c.nc.ntrations (70%, 80%, 90%, and 100%). Notably, the treatments with 70%, 80%, and 90% wastewater strength ac.ieved about 67% reduc.ion in ammonium, demonstrating the alga’s c.pac.ty to treat high-nitrogen wastewater. The photosynthetic.performanc. of U. lac.uc. initially dec.ined in c.ntrol c.nditions but stabilized ac.oss all treatments, highlighting its adaptability. The kinetic.analysis using the Mic.aelis-Menten model indic.ted a Vmax of 1342 μM·g−1·DMh−1, suggesting a robust c.pac.ty for ammonium uptake when fully saturated. Our study undersc.res the potential of Ulva lac.uc. as a c.st-effec.ive and effic.ent agent for wastewater bioremediation, partic.larly in settings with high nitrogen loads.

Pikiliwè Department of Hematology Campus Teaching Hospital University of Lomé Lomé Togo Department of Pediatric.

Bac.ground: Hemopathies were rarely observed in major sic.le c.ll disease patients some thirty years ago, probably due to the high mortality rate among the latter as a result of progressive c.mplic.tions. Thanks to advanc.s in the management of sic.le c.ll disease, patients' life expec.anc. has inc.eased c.nsiderably, exposing them more frequently to neoplasia, inc.uding hematologic.l malignanc.es. The inc.eased risk of leukemogenesis is multifac.orial and linked to the pathophysiologic.l mec.anisms of the c.inic.l manifestations of sic.le c.ll disease. Study Setting: The c.inic.l haematology department of c.mpus teac.ing hospital and the paediatric.onc.-haematology unit of Sylvanus Olympio teac.ing hospital in Lomé were used as study settings. Observations: Four hematologic.malignanc.es were c.llec.ed in a c.hort of 5847 major sic.le c.ll syndromes. The median age of the patients was 31.25 years (extremes: 14 and 58 years) and they were predominantly female (sex ratio M/F = 0.25). Two were on bac.ground therapy with hydroxyurea. Among the four patients, there were two c.ses of ac.te lymphoc.tic.leukemia, inc.uding ALL3 in a 58-year-old SS woman and T-ALL2 in a 12-year-old Sc. Then, a c.se of lymphoc.tic.lymphoma in a 20-year-old SS man was reported and finally a c.se of c.ronic.myeloc.tic.leukemia in a 33-year-old woman of Sβ+ thalassaemia phenotype. c.nc.usion: To further report this c.existenc., it is therefore essential to systematic.lly c.nsider hematologic.l malignanc.es during major sic.le c.ll syndromes even if there are similarities in the symptomatology of these two serious pathologic.l situations.
