A nanoporous immunoisolative case/capsule that encases/encapsulates insulin-secreting cells vastly expands the source of therapeutic cells available for grafting in people with diabetes, including cells from animal sources, stem cells, and genetically engineered cells. These encapsulated cellular grafts potentially provide an endogenous, renewable, and long-term source of insulin without the ne...

Encapsulation of cells in hydrogel particles has been demonstrated as an effective approach to deliver therapeutic agents. The properties of hydrogel particles, such as the chemical composition, size, porosity, and number of cells per particle, affect cellular functions and consequently play important roles for the cell-based drug delivery. Microfluidics has shown unparalleled advantages for th...

Immunity and reproductive effort are both physiologically costly and often a trade-off between these functions has been shown. In studies with damselflies, parasite load has been associated with fitness costs, such as reductions in mating success, male condition, and survival. Although each individual may be simultaneously infected by various parasite species, most studies have concentrated on ...

Introduction: Medicinal herbs are one of the most valuable Iranian National assets. Herbal essential oils have valuable therapeutic properties. Oxidation and volatile of essential oils caused some limitations in its usage. Nanoliposomes are nonometric lipid-based vesicles. Drug delivery carrier to improve delivery of therapeutic agent is one of the most well-known application of liposomal vesic...

Diabetes is one of the most prevalent, costly, and debilitating diseases in the world. Although traditional insulin therapy has alleviated the short-term effects, long-term complications are ubiquitous and harmful. For these reasons, alternative treatment options are being developed. This review investigates one appealing area: cell replacement using encapsulated islets. Encapsulation materials...

The paper reports computations for Al@C82, Sc@C82, Y@C82 and La@C82 based on encapsulation into the IPR (isolated pentagon rule) C2υ C82 cage and also on Mg@C74, Ca@C74, Sr@C74 and Ba@C74 based on encapsulation into the only C74 IPR cage. Their structural and energetic characteristics are used for evaluations of the relative production yields, employing the encapsulation Gibbs-energy terms and ...

Cyclodextrins are used to improve stability of flavor and/or oil via encapsulation of certain specific ingredients that exist by nature in food materials. The method is called often as “molecular encapsulation”, because the ingredients are encapsulated in the molecular cavity of cyclodextrins. Cyclodextrins form inclusion complexes with a variety of molecules including flavors, fats and colors....

UNLABELLED Microfluidic encapsulation methods have been previously utilized to capture cells in picoliter-scale aqueous, monodisperse drops, providing confinement from a bulk fluid environment with applications in high throughput screening, cytometry, and mass spectrometry. We describe a method to not only encapsulate single cells, but to repeatedly capture a set number of cells (here we demons...

The encapsulation of metal clusters (Pt, Ru, Rh) within MFI was achieved by exchanging cationic metal precursors into a parent zeolite (BEA, FAU), reducing them with H2 to form metal clusters, and transforming these zeolites into daughter structures of higher framework density (MFI) under hydrothermal conditions. These transformations required MFI seeds or organic templates for FAU parent zeoli...

Insect immune defenses include encapsulation and the production of lysozymes and phenoloxidase. However, the highly mobile larvae of parasitoid Ormiine flies (Ormia ochracea) can evade initial encapsulation, and instead co-opt host immune responses to form a critical respiratory funnel connecting them to outside oxygen. Here we ask how field crickets (Teleogryllus oceanicus) respond immunologic...
