Since the formation of the Research Group for the Study of Mining in Northwest Argentina (GEMINOA) a decade ago, we have been carrying out an interdisciplinary research that aims to address the mining activities developed in this region in the long-term. This paper synthesizes and expands our original depiction of colonial mining in the region, focusing on the jurisdictions of Jujuy, Salta, Catamarca, and La Rioja during the seventeenth and eighteenth centuries. With this aim in mind, it combines historical sources and archaeological data (from our own work or specialized literature). Moreover, it reflects on the concepts of hegemonic and non-hegemonic mining, considering the variables that defined them and their suitability for characterizing the colonial mining developed in the region.

Published: November 2023

Objectives
Dimethyl sulfoxide (DMSO), acetone, ethanol, and methanol are organic solvents commonly used for dissolving drugs in antimicrobial susceptibility testing. However, these solvents have certain antimicrobial activity. Currently, standardized criteria for the selection and dosage of drug solvents in drug susceptibility testing research are lacking. The study aims to provide experimental evidence for the selection and addition limit of drug solvents for the in vitro antifungal susceptibility test of Candida glabrata (C. glabrata).

Methods
According to the recommendation of the Clinical and Laboratory Standards Institute (CLSI) M27-A3, a 0.5 McFarland C. glabrata suspension was prepared and then diluted 1:1,000. Next, a gradient dilution method was used to prepare 20%, 10%, 5%, and 2.5% DMSO/acetone/ethanol/methanol. The mixture was plated onto a 96-well plate and incubated at a constant temperature of 35 °C for 48 h. The inhibitory effects of DMSO, acetone, ethanol, and methanol on C. glabrata growth and proliferation were analyzed by measuring optical density values at 600 nm (OD600 values).

Results
After 48 h incubation, the OD600 values of C. glabrata decreased to different extents in the presence of the four common organic solvents. The decrease in the OD600 values was greater with increasing concentrations within the experimental concentration range. When DMSO and acetone concentrations were higher than 2.5% (containing 2.5%) and methanol and ethanol concentrations were higher than 5.0% (containing 5.0%), the differences were statistically significant compared with the growth control wells without any organic solvent (P < 0.05).

Conclusion
All four organic solvents could inhibit C. glabrata growth and proliferation. When used as solvents for drug sensitivity testing in C. glabrata, the concentrations of DMSO, acetone, ethanol, and methanol should be below 2.5%, 2.5%, 5%, and 5%, respectively.

The recognition of insect-related damages to rice plants and the subsequent consequences for biodiversity have shown the relevance of insect communities in rice farms. This study documented the insect fauna of rice (Oryza sativa L. 1787) in two rice farms in Nnamdi Azikiwe University, Awka, Nigeria from September to November, 2022. The insects associated with the two sites were collected using handpicking, sweep net, water trap and pitfall trap methods. Data collected from the study were subjected to non-parametric t- test at 5% significant level. A total of 51,021 insects belonging to twelve insect orders were found associated with the two sites. Out of the aforementioned number, 15,120 (29.63%) were collected from site 1 while 35,901 (70.37%) were collected in site 2. There was significant difference (P <0.05) on insect abundance between site 1 and 2. Crematogaster peringueyi was found to be the most abundant (82.67%) insect in site 1, whereas Camponotus perrisi was found to be the most abundant (27.85%) in site 2. The result further showed that only Hobomok skipper had the least relative abundance (0.01%) in site 1, while Catantops quadratu, Anacatantops notatus, Dysdercus cingulatus, Crematogaster peringueyi, Dasyleurotettix infaustus and Apis mellifera had the least relative abundance (0.01%) in site 2. The diversity indices computed showed that Site 1 had a higher Simpson dominance index (0.6845), Shannon Weiner diversity index (1.07597) and Shannon Weiner evenness than site 2 (0.0019, 0.41248and 0.0393 respectively). The Margalef richness index (6.3879) of site 2 was greater than site 1 (4.9876).There is need for regular monitoring of insects in rice farms for sustainable management of the crop.

Published: November 2023

The purpose of the present investigation was to examine the relationships between seed yield and yield-attributing characters in sesame (Sesamum indicum L.) as well as evaluating their direct and indirect effects. Results indicated that number of capsules per plant (0.806) and 1000-seed weight (0.657) showed positive correlation with seed yield per plant . Path coefficient analysis indicated that number of capsules per plant (0.806) and 1000 seed weight (0.111) exhibited positive direct effect on seed yield. Positive indirect effect was observed through number of branches per plant via number of capsules per plant (0.657). Number of capsules per plant exhibited positive indirect effect via 1000 seed weight (0.111). Since, it showed strong correlation and direct effect on seed yield per plant, selecting for this trait may leads to improvement of seed yield per plant. Present study revealed that the traits viz., number of capsules per plant and 1000 seed weight association was highly desirable as the improvement in any of the yield components results into overall increase in seed yield. Selection among genotypes based on this analyses can be made for further improvement in seed yield per plant and its contributing characters.

Published: November 2023

Linagliptin (LIN) is a newly developed dipeptidyl peptidase 4 (DPP-4) inhibitor oral antidiabetic drug. LIN is considered a P-gp substrate, thus suffers from poor bioavailability (< 30%). The aim of this study was to develop and characterize LIN bioactive self-nanoemulsifying drug delivery system to circumvent its poor bioavailability and enhance its therapeutic efficacy.
Methodology: In this study, we developed solid supersaturated bioactive self-nanoemulsifying drug delivery system (Ss-bio-SNEDDS) of LIN, using clove oil as an oil phase, cremophor CO 40 as a surfactant, labrasol as a co-surfactant and Hydroxy-propyl-B-cyclodextrin (HPBCD) as a precipitation inhibitor (PI); all components are of established P-gp inhibition activity. Optimization was performed by means of triangular mixture design based on particle size, poly dispersity index (PDI) and percent transmittance. The two optimized formulations (F4 and F8) were designated and evaluated for stability and cloud point. Also, the effect of pH on particle size and PDI was assessed. Additionally, examination of particles’ surface morphology of the two optimized formulations was performed by transmission electron microscope (TEM). The prepared liquid supersaturated-SNEDDS (s-SNEDDS) were converted into solid supersaturated-SNEDDS (Ss-SNEDDS) via adsorption on microcrystalline cellulose (MCC). Further evaluations were carried out, including in vitro drug release, in vitro precipitation and in vivo studies.
Results: The optimized formulations F4 and F8 manifested promising characteristics concerning particle size (< 50 nm), PDI (< 0.3) and percent transmittance (> 99%). Stability study showed no phase separation or precipitation with rapid emulsification time. The two optimized formulations showed high cloud point temperature (above 70°C). TEM images of F4 and F8 showed spheroid like appearance with relatively smooth surface. Results of the in vivo study in rats revealed a significant increase in AUC of solid-F4, solid-F8 and solid supersaturated-F4 (S-F4, S-F8 and Ss-F4) by 2.32, 2.89 and 2.54 folds, respectively compared to LIN solution; with a noticeable reduction in blood glucose level at each point.
Conclusion: In a nutshell, Ss-bio-SNEDDS are considered as auspicious nano-carriers for LIN with the virtue of augmented bioavailability and possible dose reduction.

AbstractA gradient current collector (GCC) can encourage preferential Li metal deposition on the more lithiophilic/conductive bottom of 3D anodes, enhancing the reversibility of the battery. However, as the deposition proceeds, the reduction of lithophilicity/conductivity easily causes the disturbance of Li+ flux. Herein, a brand‐new bicomponent‐bidirectional gradient current collector (BGCC) is proposed. The BGCC constructs slow‐release additives with reverse gradient distribution (SA gradient) based on GCC, allowing it to build a position‐responsive solid electrolyte interface layer. Additionally, as the deposition amount increases, the slow‐release additives will release more and present a stronger ability to regulate Li+ flux, ensuring the anodereversibility under large deposition amounts conditions. Consequently, asymmetric cells can exhibit high reversibility with an average coulomb efficiency (CE) of 97.8% and sustain over 200 cycles using carbonate‐based electrolytes. The Li@BGCC||LiFePO4 full cells hold a capacity retention of 94.8% over 400 cycles with thin Li. Notably, even at low temperatures, the Li@BGCC anodes can exhibit a CE as high as 98.46% and excellent capacity retention of 97.8% after 100 cycles paired with NCM811 cathodes. This strategy opens up a new direction for the development of 3D current collectors.

Published: November 2023

AbstractAggregation‐induced emission (AIE) materials are considered promising photocatalyst candidates due to their robust light‐harvesting and efficient photoexcitation, if their photoexcited carriers can be separated effectively. Herein, by skillfully selecting multi‐alkynyl ligands instead of phenylacetylene to construct multi‐channel charge separation, copper‐phenylacetylide (CP‐1) with AIE properties is successfully transformed into efficient photocatalysts CP‐2P (copper‐1,4‐diethynylbenzene) and CP‐2M (copper‐1,3‐diethylnylbenzene). In these structures, the multi‐alkynyl ligands connects the copper‐ladder into multi‐dimensional metal‐organic frameworks with greatly reduced bandgap, enhances charge transfer and separation, and facilitated oxygen adsorption and activation. As a representative, CP‐2P has the best photocatalytic activity and stability for photocatalytic aerobic oxidation, such as thioanisole oxidation (conv. > 99%, methyl phenyl sulfoxide sel. ≧ 94%), benzyl alcohol oxidation (conv. > 99%, benzaldehyde sel. > 99%) and benzylamine oxidation (conv. > 99%, N‐benzylidene benzylamine sel. > 99%), which can be used for large‐scale sunlight‐driven organic photosynthesis. This work confirms the feasibility of controlled conversion of the conventional copper‐alkynyl from AIE material to efficient photocatalyst using charge separation strategy, which provides an important guidance for the rational design of new high‐efficiency photocatalyst.
