Why Liquidity Matters: A Financial Planning and Investment Discussion for Plastic Surgeons.

Plastic surgeons should understand the importance of maintaining liquidity as part of a robust household financial planning and investment strategy. Although investors rightly focus on achieving solid long-term returns, our experience suggests that many plastic surgeons often pay too little attention to liquidity management in their outlook, and some may experience stress as a result. This article discusses why liquidity management matters both in terms of each surgeon's unique career and in the context of today's dynamic investment opportunities and risks.

Cryopreserved red blood cells maintain allosteric control of oxygen binding when utilizing trehalose as a cryoprotectant.

One of the most common life-saving medical procedures is a red blood cell (RBC) transfusion. Unfortunately, RBCs for transfusion have a limited shelf life after donation due to detrimental storage effects on their morphological and biochemical properties. Inspired by nature, a biomimetics approach was developed to preserve RBCs for long-term storage using compounds found in animals with a natural propensity to survive in a frozen or desiccated state for decades.

A Wealth and Investment Primer for Plastic Surgeons: The Two Pillar Framework.

Sound investing, analogous to maintaining good health, is a long-term process that must be continuously nurtured and strengthened. This article will describe how adhering to a simple, two-pillar framework can help plastic surgeons secure superior wealth generation. Our first pillar is anchored on developing a consistent savings plan geared to circumstances and lifestyle goals at each career stage.

LEAfing through literature: late embryogenesis abundant proteins coming of age-achievements and perspectives.

To deal with increasingly severe periods of dehydration related to global climate change, it becomes increasingly important to understand the complex strategies many organisms have developed to cope with dehydration and desiccation. While it is undisputed that late embryogenesis abundant (LEA) proteins play a key role in the tolerance of plants and many anhydrobiotic organisms to water limitation, the molecular mechanisms are not well understood. In this review, we summarize current knowledge of the physiological roles of LEA proteins and discuss their potential molecular functions.

Functional and Conformational Plasticity of an Animal Group 1 LEA Protein.

Group 1 (Dur-19, PF00477, LEA_5) Late Embryogenesis Abundant (LEA) proteins are present in organisms from all three domains of life, Archaea, Bacteria, and Eukarya. Surprisingly, is the only genus known to include animals that express group 1 LEA proteins in their desiccation-tolerant life-history stages. Bioinformatics analysis of circular dichroism data indicates that the group 1 LEA protein LEA1 is surprisingly ordered in the hydrated state and undergoes during desiccation one of the most pronounced disorder-to-order transitions described for LEA proteins from .

Sonoporation enables high-throughput loading of trehalose into red blood cells.

Despite recent advances in biostabilization, clinical blood supplies still experience shortages and storage limitations for red blood cells (RBCs) have not yet been sufficiently addressed. Storing RBCs in a frozen or dried state is an appealing solution to address storage limitations, but many promising cryoprotectants, including the non-reducing sugar trehalose, are impermeant to mammalian cell membranes and cannot be utilized effectively using currently available compound-loading methods. We found that transient pore formation induced by ultrasound and microbubbles (sonoporation) offers an effective means of loading trehalose into RBCs to facilitate long-term storage in a frozen or desiccated state.

Liquid-liquid phase separation promotes animal desiccation tolerance.

Proteinaceous liquid-liquid phase separation (LLPS) occurs when a polypeptide coalesces into a dense phase to form a liquid droplet (i.e., condensate) in aqueous solution.

Ultrasound-induced molecular delivery to erythrocytes using a microfluidic system.

Preservation of erythrocytes in a desiccated state for storage at ambient temperature could simplify blood transfusions in austere environments, such as rural clinics, far-forward military operations, and during space travel. Currently, storage of erythrocytes is limited by a short shelf-life of 42 days at 4 °C, and long-term preservation requires a complex process that involves the addition and removal of glycerol from erythrocytes before and after storage at -80 °C, respectively. Natural compounds, such as trehalose, can protect cells in a desiccated state if they are present at sufficient levels inside the cell, but mammalian cell membranes lack transporters for this compound.

Structural properties and cellular expression of AfrLEA6, a group 6 late embryogenesis abundant protein from embryos of Artemia franciscana.

Late embryogenesis abundant (LEA) proteins are intrinsically disordered proteins (IDPs) commonly found in anhydrobiotic organisms and are frequently correlated with desiccation tolerance. Herein we report new findings on AfrLEA6, a novel group 6 LEA protein from embryos of Artemia franciscana. Assessment of secondary structure in aqueous and dried states with circular dichroism (CD) reveals 89% random coil in the aqueous state, thus supporting classification of AfrLEA6 as an IDP.

Role of Intrinsic Disorder in Animal Desiccation Tolerance.

This review compares the molecular strategies employed by anhydrobiotic invertebrates to survive extreme water stress. Intrinsically disordered proteins (IDPs) play a central role in desiccation tolerance in all species investigated. Various hypotheses about the functions of anhydrobiosis-related intrinsically disordered (ARID) proteins, including late embryogenesis abundant (LEA) and tardigrade-specific intrinsically disordered proteins, are evaluated by broad sequence characterization.

Potential functions of LEA proteins from the brine shrimp Artemia franciscana - anhydrobiosis meets bioinformatics.

Late embryogenesis abundant (LEA) proteins are a large group of anhydrobiosis-associated intrinsically disordered proteins, which are commonly found in plants and some animals. The brine shrimp Artemia franciscana is the only known animal that expresses LEA proteins from three, and not only one, different groups in its anhydrobiotic life stage. The reason for the higher complexity in the A.
