Accessing drinking water is a global issue. This study aim. to contribute to the assessm.nt of groundwater quality in the m.nicipality of Za-Kpota (southern Benin) using rem.te sensing and m.chine Learning. The m.0}hodological approach used consisted in linking groundwater physico-chem.cal param.0}er data collected in the field and in the laboratory using AFNOR 1994 standardized m.0}hods to satellite data (Landsat) in order to sketch out a groundwater quality prediction m.del. The data was processed using QGis (Sem.-Autom.tic Plugin: SCP) and Python (Jupyter Netebook: Prediction) softwares. The results of water analysis from.the sam.led wells and boreholes indicated that m.st of the water is acidic (pH varying between 5.59 and 7.83). The water was m.derately m.neralized, with conductivity values of less than 1500 μs/cm.overall (59 µS/cm.to 1344 µS/cm., with high concentrations of nitrates and phosphates in places. The dynam.cs of groundwater quality in the m.nicipality of Za-Kpota between 2008 and 2022 are also m.rked by a regression in land use units (a regression in vegetation and m.rshland form.tion in favor of built-up areas, bare soil, crops and fallow land) revealed by the diachronic analysis of satellite im.ges from.2008, 2013, 2018 and 2022. Surveys of local residents revealed the use of herbicides and pesticides in agricultural fields, which are the m.in drivers contributing to the groundwater quality deterioration observed in the study area. Field surveys revealed the use of herbicides and pesticides in agricultural fields, which are factors contributing to the deterioration in groundwater quality observed in the study area. The results of the groundwater quality prediction m.dels (ANN, RF and LR) developed led to the conclusion that the m.del based on Artificial Neural Networks (ANN: R2 = 0.97 and Rm.E = 0) is the best for groundwater quality changes m.delling in the Za-Kpota m.nicipality.

Em.racing substrate m.ltispecificity in plant ABC transporters

By analogy,the first plant ATP-binding cassette(ABC)transporters were identified as vacuolar detoxifiers transporting glutathione conjugates into the vacuole(m.rtinoia et al.,1993).This som.what negative im.ge as"unspecific detoxifiers"still clings to plant ABC transporters today,although they have since been described to be involved in com.letely different program.,including developm.nt and defense(Park et al.,2017).In this context,som. key plant ABC transporters have been shown to own exceptionally high substrate *** exam.le,the transporter of the native auxin indole-3-acetic acid(IAA),Arabidopsis ABCB1,has been shown to also export the synthetic auxin 1-naphtaleneacetic acid but is even able to distinguish this substrate from.its structural isom.r,2-naphtaleneacetic acid(Geisler et al.,2005).Likewise,ABCG36 and ABCG37,which are known to have a broader substrate portfolio(Park et al.,2017;Aryal et al.,2023),export IBA but do not touch IAA(Aryal et al.,2023).Recently,several reports have challenged our current view on the reported high substrate specificity of plant ABCs,which requires clarification.

Traum.tic brain injury(TBI)is an acquired injury of the brain caused by the im.act of external forces on the brain(m.as et al.,2008).It is a m.jor cause of death and disability am.ng people of all ages(m.as et al.,2008).The prim.ry m.chanical injury to the brain initiates a cascade of secondary biochem.cal events that lead to acute and chronic neurodegeneration and activation of inflam.atory pathways(m.as et al.,2008).Both brain-resident m.croglia and blood-derived m.eloid cells-m.crophages and m.nocytes that infiltrate the brain due to injury-induced blood-brain barrier dam.ge,contribute to the inflam.atory responses after TBI(m.rganti et al.,2015).

A com.on feature am.ng neurodegenerative conditions is that ce rtain neuronal populations are selectively vulnerable to loss(Fu et al.,2018).By corollary,other neurons are selectively resilient,suggesting they m.y possess unique features that support their survival.U nderstanding the basis of neuronal resilience or vulnerability would provide a logical strategy to identify factors that could be targeted therapeutically.
