Distinct Charge and Spin Recovery Dynamics in a Photoexcited Mott Insulator.

Pump-probe response of the spin-orbit coupled Mott insulator Sr_{2}IrO_{4} reveals a rapid creation of low-energy optical weight and suppression of three-dimensional magnetic order on laser pumping. Postpump there is a quick reduction of the optical weight but a very slow recovery of the magnetic order-the difference is attributed to weak interlayer exchange in Sr_{2}IrO_{4} delaying the recovery of three-dimensional magnetic order. We suggest that the effect has a very different and more fundamental origin.

The present investigation aims to develop a reactive oxygen species (ROS) and esterase-responsive biodegradable mannosylated polyurethane to effectively deliver the encapsulated antileishmanial drug amphotericin B (AmB) selectively to infected macrophage cells. Owing to suitable amphiphilic balance, the as-synthesized glycosylated polyurethane () with aryl boronic ester-based diol () moiety as ROS-trigger, water-soluble mannose pendants, and fluorescent 4,4-difluoro-4-bora-3a,4a-diaza--indacene (BODIPY) chain ends for bioimaging formed nanoaggregates in an aqueous medium as confirmed by H NMR spectroscopy, dynamic light scattering (DLS), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and critical aggregation concentration (CAC) measurements. Aided by two endogenous stimuli present in phagolysosome, ROS and esterase, AmB-encapsulated polymeric nanoaggregates as drug delivery vehicles achieved an efficient reduction of both and intracellular amastigote burden compared to the free AmB.

Technical and management coaching for government institutions: Lessons learned and health systems transformations across 8 countries in sub-Saharan Africa and India.

Traditional engagement with local governments often relies on financial and human resources from international or local partners, leading to direct implementation by organizations, which can hinder sustainability. While some organizations include sustainability indicators, few focus on transferring technical and financial ownership to governments. The Challenge Initiative (TCI) uses a phased coaching model-lead, assist, observe, and monitor-to build local government capacity for scaling family planning (FP) and adolescent and youth sexual and reproductive health (AYSRH) programs.

Chemical Basis of the Traditional Ayurvedic Detoxification Process of the Toxic Medicinal Plant .

Assessing the efficacy of synthetic compounds foliar sprays in alleviating terminal heat stress in late-sown wheat ().

Detrimental effects of terminal heat stress could be mitigated by exogenous application of synthetic compounds by preserving cell membrane integrity and protecting against oxidative damage. A field experiment was conducted to test the application of seven synthetic compounds on wheat growth traits: (1) thiourea (20 mM and 40mM); (2) potassium nitrate (1% and 2%); (3) sodium nitroprusside (400 μg mL-1 and 800μg mL-1 ); (4) dithiothreitol (25 ppm and 50ppm); (5) salicylic acid (100 ppm and 200ppm); (6) thioglycolic acid (200 ppm and 500ppm); and (7) putrescine (4 mM and 6mM). These compounds were applied at the anthesis and grain-filling stages to enhance physio-biochemical traits and yield attributes of wheat (Triticum aestivum ) cvs GW-11 and GW-496 under terminal heat stress.

Synthesis of -dA Damaged DNAs to Probe the Replication Ability of Human Translesion Polymerases.

The DNA adducts formed by the alkenylbenzene natural products, safrole (SF) and methyleugenol (MEG) are primarily attributed to their reported carcinogenic properties. Herein, we report a concise strategy to access -Ac-SF/MEG-dA phosphoramidites, which were selectively incorporated into DNA oligonucleotides by solid-phase DNA synthesis. The replication studies using human polymerases hpolκ and hpolη showed that both polymerases replicate these adducts error-free, which indicates that these polymerases do not contribute to the adduct-induced mutagenicity.

Aging in a weighted ensemble of excitable and self-oscillatory neurons: The role of pairwise and higher-order interactions.

We investigate the aging transition in networks of excitable and self-oscillatory units as the fraction of inherently excitable units increases. Two network topologies are considered: a scale-free network with weighted pairwise interactions and a two-dimensional simplicial complex with weighted scale-free pairwise and triadic interactions. Without triadic interactions, the aging transition from collective oscillations to oscillation death (inhomogeneous stationary states) can occur either suddenly or through an intermediate state of partial oscillation.
