Model systems are critical in biomedical and preclinical research. Animal and in vitro models serve an important role in our current understanding of human physiology, disease pathophysiology, and therapy development. However, if the system is between cell culture and animal models, it may be able to overcome the knowledge gap that exists in the current system.

Enhancing the wound healing potential using earthworm clitellum factors and elucidating its molecular mechanism in an in-vitro and earthworm model.

Earthworm, Eudrilus eugeniae cannot survive and regenerate without clitellum segments. In regenerating worms, the clitellum's epithelial and circular muscular layers are reduced to one-third, and longitudinal cell layers to half. In C2C12 cells, Clitellum Factors (CF - 5, 25 and 50%) and Regenerative Clitellum Factors (RCF - 5, 25, 50, 75%) ameliorate the cell viability up to 20-28% and 30-38% respectively than the control.

Stereochemical Shape Morphing in Diels-Alder Polymer Networks.

The intrinsic reversibility of dynamic covalent bonding, such as the furan-maleimide Diels-Alder (DA) cycloaddition reactions, enables reprocessable, self-healing polymer materials that can be reconfigured via the mechanism of solid-state plasticity. In this work, the temperature-dependent exchange rates of stereochemically distinct endo and exo DA bonds are leveraged to achieve tunable, temperature- and stress-activated shape morphing in Diels-Alder polymer (DAP) networks. Through thermal annealing, ≈35% of endo DA isomers are converted in neat DAP networks to the thermodynamically favored exo form, achieving ≈97% exo after complete annealing at 60 °C.

Understanding the molecular mechanism of regeneration through apoptosis-induced compensatory proliferation studies - updates and future aspects.

AICP is a crucial process that maintaining tissue homeostasis and regeneration. In the past, cell death was perceived merely as a means to discard cells without functional consequences. However, during regeneration, effector caspases orchestrate apoptosis, releasing signals that activate stem cells, thereby compensating for tissue loss across various animal models.

Hybrid Polymer Salogels for Reversible Entrapment of Salt-Hydrate-Based Thermal Energy Storage Materials.

One of the challenges preventing wide use of inorganic salt hydrate phase change materials (PCMs) is their low viscosity above their melting point, leading to leakage, phase segregation, and separation from heat exchanger surfaces in thermal management applications. The development of a broad strategy for using polymers that provide tunable, temperature-reversible shape stabilization of a variety of salt hydrates by using the lowest possible polymer concentrations is hindered by differences in solubility and gelation behavior of polymers with change in the type of ion. This work addressed the challenge of creating robust, temperature-responsive shape-stabilizing polymer gels (i.

Warmer autumns and winters could reduce honey bee overwintering survival with potential risks for pollination services.

Honey bees and other pollinators are critical for food production and nutritional security but face multiple survival challenges. The effect of climate change on honey bee colony losses is only recently being explored. While correlations between higher winter temperatures and greater colony losses have been noted, the impacts of warmer autumn and winter temperatures on colony population dynamics and age structure as an underlying cause of reduced colony survival have not been examined.

The molecular mechanisms underlying the regeneration process in the earthworm, Perionyx excavatus exhibit indications of apoptosis-induced compensatory proliferation (AICP).

Regeneration is a multifaceted biological phenomenon that necessitates the intricate orchestration of apoptosis, stem cells, and immune responses, culminating in the regulation of apoptosis-induced compensatory proliferation (AICP). The AICP context of research is observed in many animal models like in Hydra, Xenopus, newt, Drosophila, and mouse but so far not reported in earthworm. The earthworm Perionyx excavatus is used in the present study to understand the relationship between AICP-related protein expression and regeneration success in different conditions (normal regeneration and abnormal multiple bud formation).

Analysis of Medicare Patients Treated with Pimavanserin versus Other Atypical Antipsychotics: A Cost-Offset Model Evaluating Skilled Nursing Facility Stays and Long-Term Care Admissions in Parkinson's Disease Psychosis.

Background: Patients with Parkinson's disease psychosis (PDP) treated with pimavanserin (PIM) versus other atypical antipsychotics (AAPs) including quetiapine (QUE) may have health-care cost savings due to fewer skilled nursing facility-stays (SNF-stays) and long-term care admissions (LTCA).

Methods: A decision analytic model was developed using the 2019 Medicare Patient Driven Payment Model (PDPM) to estimate SNF-stays and LTCA associated per-patient- per-year (PPPY) facility and rehabilitation costs among patients that initiated PIM vs QUE or vs other-AAPs (i.e, quetiapine, risperidone, olanzapine, aripiprazole).

Understanding the Multi-Functional Role of TCTP in the Regeneration Process of Earthworm, Perionyx excavatus.

Background: Regeneration is a highly complex process that requires the coordination of numerous molecular events, and identifying the key ruler that governs is important to investigate. While it has been shown that TCTP is a multi-functional protein that regulates cell proliferation, differentiation, apoptosis, anti-apoptosis, stem cell maintenance, and immune responses, but only a few studies associated to regeneration have been reported. To investigate the multi-functional role of TCTP in regeneration, the earthworm Perionyx excavatus was chosen.

High Quantum Yield Shortwave Infrared Luminescent Tracers for Improved Sorting of Plastic Waste.

More complete recycling of plastic waste is possible only if new technologies that go beyond state-of-the-art near-infrared (NIR) sorting are developed. For example, tracer-based sorting is a new technology that explores the upconversion or down-shift luminescence of special tracers based on inorganic materials codoped with lanthanide ions. Specifically, down-shift tracers emit in the shortwave infrared (SWIR) spectral range and can be detected using a SWIR camera preinstalled in a state-of-the-art sorting machine for NIR sorting.

To investigate real-world chimeric antigen receptor (CAR) T-cell therapy treatment patterns. Relapsed/refractory large B-cell lymphoma patients who received CAR T-cell therapy were identified. Patient characteristics, setting of CAR T-cell infusion, incidence of CAR T-cell therapy-associated adverse events and healthcare resource utilization were assessed.

Climate analogs can catalyze cross-regional dialogs for US specialty crop adaptation.

Communication theory suggests that interactive dialog rather than information transmission is necessary for climate change action, especially for complex systems like agriculture. Climate analogs-locations whose current climate is similar to a target location's future climate-have garnered recent interest as transmitting more relatable information; however, they have unexplored potential in facilitating meaningful dialogs, and whether the way the analogs are developed could make a difference. We developed climate context-specific analogs based on agriculturally-relevant climate metrics for US specialty crop production, and explored their potential for facilitating dialogs on climate adaptation options.
