Engineering and physicochemical characterization of a novel, stable, symmetric bispecific antibody with dual target-binding using a common light chain.

Bispecific antibodies (BsAbs) have emerged as a major class of antibody therapeutics owing to their substantial potential in disease treatment. While several BsAbs have been successfully approved in recent years, ongoing development efforts continue to focus on optimizing various BsAbs tailored to particular antigens and action mechanisms, aiming to achieve favorable physicochemical properties. BsAbs generally encounter challenges due to their unfavorable physicochemical characteristics and poor manufacturing efficiencies, highlighting the need for optimization to achieve reliable productivity and developability.

Hereditary transthyretin amyloidosis with hydrocephalus at 27 years old: A case report.

Unlabelled: Hereditary transthyretin amyloidosis is autosomal dominant and results from mutations in the transthyretin gene. The Val30Met variant is the most common genetic mutation, although mutations vary within populations. More than 150 mutations in transthyretin have been reported; however, the Leu111Glu (p.

Controlled Release of Oxygen from Calcium Peroxide in a Weak Acidic Condition by Stabilized Amorphous Calcium Carbonate Nanocoating for Biomedical Applications.

Calcium peroxide (CaO) has recently attracted much attention as an oxygen-releasing biomaterial for tissue engineering. CaO has also been used in cancer therapies, such as photodynamic therapy. However, the uncontrollability of oxygen release after immersion in water is a challenge.

Ultra-Rapid and Specific Gelation of Collagen Molecules for Transparent and Tough Gels by Transition Metal Complexation.

Collagen is the most abundant protein in the human body and one of the main components of stromal tissues in tumors which have a high elastic modulus of over 50 kPa. Although collagen has been widely used as a cell culture scaffold for cancer cells, there have been limitations when attempting to fabricate a tough collagen gel with cells like a cancer stroma. Here, rapid gelation of a collagen solution within a few minutes by transition metal complexation is demonstrated.

Development of temperature dependent oxygen releasable nanofilm by modulating oxidation state of myoglobin.

Controlled release of oxygen from myoglobin was achieved by modulating autoxidation of oxymyoglobin using ascorbic acid as a reductant by temperature variation. Long-term storage, prompt release and re-storage of oxygen were also available with this system. Furthermore, 20 nm thick nanofilms composed of oxymyoglobin and type I collagen containing ascorbic acid could successfully show autoxidation of oxymyoglobin in response to environmental temperature.

Diverse phenotypic expression associated with the same genetic variant in female heterozygote patients of Anderson-Fabry disease: a case series.

Background: Anderson-Fabry disease (AFD) is an X-linked lysosomal storage disorder resulting from a mutation of alpha-galactosidase A gene (), causing deficiency in alpha-galactosidase activity. The enzyme deficit can lead to storage of globotriaosylceramide in various organs including heart. Studies suggest that vasospastic angina (VSA) is associated with AFD.

Peroxisome proliferator-activated receptors (PPARs) have multiple binding points that accommodate ligands in various conformations: phenylpropanoic acid-type PPAR ligands bind to PPAR in different conformations, depending on the subtype.

Human peroxisome proliferator-activated receptors (hPPARs) are ligand-dependent transcription factors that control various biological responses, and there are three subtypes: hPPARα, hPPARδ, and hPPARγ. We report here that α-substituted phenylpropanoic acid-type hPPAR agonists with similar structure bind to the hPPAR ligand binding domain (LBD) in different conformations, depending on the receptor subtype. These results might indicate that hPPAR ligand binding pockets have multiple binding points that can be utilized to accommodate structurally flexible hPPAR ligands.
