Past foraminiferal acclimatization capacity is limited during future warming.

Climate change affects marine organisms, causing migrations, biomass reduction and extinctions. However, the abilities of marine species to adapt to these changes remain poorly constrained on both geological and anthropogenic timescales. Here we combine the fossil record and a global trait-based plankton model to study optimal temperatures of marine calcifying zooplankton (foraminifera, Rhizaria) through time.

Intestinal-Target and Glucose-Responsive Smart Hydrogel toward Oral Delivery System of Drug with Improved Insulin Utilization.

An intelligent insulin delivery system targeting intestinal absorption and glucose responsiveness can enhance the bioavailability through oral insulin therapy, offering promising diabetes treatment. In this paper, a glucose and pH dual-response polymer hydrogel using carboxymethyl agarose modified with 3-amino-phenylboronic acid and l-valine (CPL) was developed as an insulin delivery carrier, exhibiting excellent biocompatibility and effective insulin encapsulation. The insulin encapsulated in the hydrogel (Ins-CPL) was released in a controlled manner in response to the stimulation of blood glucose and pH levels with higher levels of intracellular uptake and utilization of insulin in the intestinal environment simultaneously.

Targeting the stimulator of interferon genes (STING) in breast cancer.

Breast cancer has a high occurrence rate globally and its treatment has demonstrated clinical efficacy with the use of systemic chemotherapy and immune checkpoint blockade. Insufficient cytotoxic T lymphocyte infiltration and the accumulation of immunosuppressive cells within tumours are the primary factors responsible for the inadequate clinical effectiveness of breast cancer treatment. The stimulator of interferon genes (STING) represents a pivotal protein in the innate immune response.

The biological carbon pump in CMIP6 models: 21st century trends and uncertainties.

The biological carbon pump (BCP) stores ∼1,700 Pg C from the atmosphere in the ocean interior, but the magnitude and direction of future changes in carbon sequestration by the BCP are uncertain. We quantify global trends in export production, sinking organic carbon fluxes, and sequestered carbon in the latest Coupled Model Intercomparison Project Phase 6 (CMIP6) future projections, finding a consistent 19 to 48 Pg C increase in carbon sequestration over the 21st century for the SSP3-7.0 scenario, equivalent to 5 to 17% of the total increase of carbon in the ocean by 2100.

Antimicrobial peptides/ciprofloxacin-loaded O-carboxymethyl chitosan/self-assembling peptides hydrogel dressing with sustained-release effect for enhanced anti-bacterial infection and wound healing.

Bacteria-induced wound infections and multifunctional hydrogels have received widespread attention in wound repair.

Bnip3L, also known as NIX, is a homolog of the E1B 19K/Bcl-2 binding and pro-apoptotic protein Bnip3 which can bind to Bcl-2 to elaborate that effect. In tumor cells, Bnip3L played a role in tumor growth inhibition, but some studies argued hypoxia-induced autophagy via Bnip3L was a survival mechanism that promoted tumor progression. In heart muscle, it related to decreased myocardial function.

The member of high temperature requirement family HtrA2 participates in neuronal apoptosis after intracerebral hemorrhage in adult rats.

The members of high-temperature requirement (HtrA) family are evolutionarily conserved serine proteases that combine a trypsin-like protease domain with at least one PDZ interaction domain. HtrA2, a special one, is mainly located in mitochondria and required for maintaining homeostasis. Once released into cytoplasm, HtrA2 contributes to apoptosis via caspase-dependent and -independent pathways.
