Aligned pore structures present many advantages when conceiving biomaterial strategies for treatment of musculoskeletal disorders. Aligned ice templating (AIT) is one of the many different techniques capable of producing anisotropic porous scaffolds; its high versatility allows for the formation of structures with tunable pore sizes, as well as the use of many different materials. AIT has been found to yield improved compressive properties for bone tissue engineering (BTE), as well as higher tensile strength and optimized cellular alignment and proliferation in tendon and muscle repair applications. This review evaluates the work that has been done in the last decade toward the production of aligned pore structures by AIT with an outlook on the musculoskeletal system. This work describes the fundamentals of the AIT technique and focuses on the research carried out to optimize the biomechanical properties of scaffolds by modifying the pore structure, categorizing by material type and application. Related topics including growth factor incorporation into AIT scaffolds, drug delivery applications, and studies about immune system response will be discussed.

Heterogeneous ice nucleation is a widespread phenomenon in nature. Despite extensive research on ice nucleation near biological antifreeze proteins, a probe for ice nucleation and growth processes at the atomic level is still lacking. Herein, we present simulation evidence of the heterogeneous ice nucleation process on the ice-binding surface (IBS) of the antifreeze protein (TmAFP).

Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity, deliver essential ecosystem services and contribute to planetary stability. We present Antarctica's first comprehensive ecosystem classification and map of ice-free lands, which host most of the continent's biodiversity.

Vivian Campagna, DNP, RN-BC, CCM, ICE-CCP is the Chief Industry Relations Officer of the Commission for Case Manager Certification, the first and largest nationally accredited organization that certifies more than 50,000 professional case managers and disability management specialists. The Commission oversees the process of case manager certification with its CCM® credential and disability management specialist certification with its CDMS® credential. With more than 30 years of case management experience, Vivian spent much of her professional career in acute care case management, prior to joining the Commission.
Purpose: Interprofessional teams are increasingly being recognized as a best practice for enhancing cooperation among multiple disciplines in delivering person-centered care and improving outcomes. Unlike previous models, such as the multidisciplinary team in which each profession or discipline remained largely siloed, with interprofessional teams collaboration occurs across disciplines. For case managers, the interprofessional team concept aligns with the collaborative, professionally diverse nature of the field of practice.

The neuropeptide phoenixin (PNX) may be involved in regulating the hypothalamic-pituitary-gonadal (HPG) axis and inflammatory responses. This study aims to investigate the role of PNX in the regulation of HPG axis function in ice hockey players and its impact on body composition. This cross-sectional study included 65 male ice hockey players aged 18-22, divided into untrained, non-elite athlete, and elite athlete groups.

In various applications, the pore structure of a porous medium must be controlled to facilitate heat and mass transfer, which considerably influence the system performance. Freeze-casting is a versatile technique for creating aligned pores; However, because of the complexity of the associated equipment and the energy inefficiency of liquid-nitrogen-based cooling in a room-temperature environment, limits scalability for industrial applications. This study is aimed at establishing a novel freeze-casting strategy with a simple mold design combining heat-conductive and insulating materials for long-range pore alignment via directional ice growth under deep-freezing conditions, rendering it feasible for large-scale production.
