Social life cycle assessment of industrial gold mining in Mali.

Gold mining in Mali contributes significantly to the country's socio-economic growth, employing hundreds of people and generating considerable export revenues and income. At the same time, gold mining still has a bad reputation in public opinion due to the environmental and socio-economic challenges it poses. It is therefore important to integrate Mali's gold mining sector into a framework of social responsibility, using the Social Life Cycle Assessment (S-LCA) approach to identify and understand social opportunities and challenges.

Guanine-based spin valve with spin rectification effect for an artificial memory element.

Non-volatile electronic memory elements are very attractive for applications, not only for information storage but also in logic circuits, sensing devices and neuromorphic computing. Here, a ferroelectric film of guanine nucleobase is used in a resistive memory junction sandwiched between two different ferromagnetic films of Co and CoCr alloys. The magnetic films have an in-plane easy axis of magnetization and different coercive fields whereas the guanine film ensures a very long spin transport length, at 100 K.

Repurposing Nano Curcumin: Unveiling its Therapeutic Potential in Diabetic Nephropathy.

Currently, diabetic nephropathy (DN) stands as the predominant global cause of endstage renal disease. Many scientists believe that diabetes will eventually spread to pandemic levels due to the rising prevalence of the disease. While the primary factor leading to diabetic nephropathy is vascular dysfunction induced by hyperglycemia, several other pathological elements, such as fibrosis, inflammation, and oxidative stress, also contribute to the progression of the disease.

In this paper, three new species, Wang & Huang, , Wang & Huang, and Wang & Huang, , are described and illustrated, with notes on one species, Hopper & Woolley, new to China.

Pathogens spread by high-altitude windborne mosquitoes.

Recent studies have revealed that many mosquito species regularly engage in high-altitude windborne migration, but its epidemiological significance was debated. The hypothesis that high-altitude mosquitoes spread pathogens over large distances has not been directly tested. Here, we report for the first time that high-altitude windborne mosquitoes are commonly infected with arboviruses, protozoans, and helminths affecting vertebrates and humans, and provide the first description of this pathogen-vector aerial network.

Malian field isolates provide insight into Plasmodium malariae intra-erythrocytic development and invasion.

Plasmodium malariae is the third most prevalent human malaria parasite species and contributes significantly to morbidity. Nevertheless, our comprehension of this parasite's biology remains limited, primarily due to its frequent co-infections with other species and the lack of a continuous in vitro culture system. To effectively combat and eliminate this overlooked parasite, it is imperative to acquire a better understanding of this species.

Design, synthesis, in vitro, and in silico studies of 4-fluorocinnamaldehyde based thiosemicarbazones as urease inhibitors.

Clinically significant problems such as kidney stones and stomach ulcers are linked to the activation of the urease enzyme. At low pH, this enzyme gives an ideal environment to Helicobacter pylori in the stomach which is the cause of gastric ulcers and peptic ulcers. In recent work, we have developed a library of 4-fluorocinnamaldehyde base thiosemicarbazones and assessed them for their potential against urease enzyme.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.
