The mobilization of storage reserves, with particular emphasis on storage proteins of Mucuna pruriens (L.) DC., cotyledons, and embryo was investigated from the ultrastructural and biochemical points of view. Proteins and starch were the two main storage substances in cotyledons, and proteins and lipids were the main ones in the embryo. Embryo protein bodies were smaller and fewer in number than those of cotyledons. Structural and ultrastructural data determined between 24 and 48 h after imbibition and between 48 and 72 h after imbibition, the end of significant embryo and cotyledon protein mobilization, respectively, indicating more precocious storage protein mobilization in the axis than cotyledons. Moreover, storage protein mobilization in embryo and cotyledons occurred before the end of germination. Water soluble proteins were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis, producing 29 bands with molecular weights from 14 to 90 KDa. Embryo extract contained more proteins than cotyledon extract, contained seven characteristic bands, and showed a higher variability of the optical density trend than cotyledon.

Fanconi anemia (FA) is a congenital multisystem disorder characterized by early-onset bone marrow failure (BMF) and cancer susceptibility. While gene addition and repair therapies are being considered as treatment options, depleted hematopoietic stem cell (HSC) pools, poor HSC mobilization, compromised survival during transduction, and increased sensitivity to conventional conditioning strategies limit eligibility for FA patients to receive gene therapies. As an alternative approach, we explored protein replacement by mRNA delivery via lipid nanoparticles (LNPs).

Background: Bok is a poorly characterized Bcl-2 protein family member with roles yet to be clearly defined. It is clear, however, that Bok binds strongly to inositol 1,4,5-trisphosphate (IP) receptors (IPRs), which govern the mobilization of Ca from the endoplasmic reticulum, a signaling pathway required for many cellular processes. Also known is that Bok has a highly conserved phosphorylation site for cAMP-dependent protein kinase at serine-8 (Ser-8).

Stay-green (SG) and stem reserve mobilization (SRM) are two significant mutually exclusive traits, which contributes to grain-filling during drought and heat stress in wheat. The current research was conducted in a genome-wide association study (GWAS) panel consisting of 278 wheat genotypes of advanced breeding lines to find the markers linked with SG and SRM traits and also to screen the superior genotypes. SG and SRM traits, viz.

In the pursuit of more sustainable diets, researchers have been studying ways to promote a transition from animal- to plant-based meals in foodservice contexts by influencing participants' conscious choices through names, labels, claims, and information. This critical review found that these interventions usually mobilize only those already engaged in reducing the consumption of animal products and often only during the intervention period, failing to influence those who eat most meat or to create long-lasting effects. Analyzing the choice for vegetarian meals against meals with meat in recently published studies conducted in foodservice contexts, we argue that the transition to more sustainable diets should rely less on consumers' willpower and more on public policies and institutional measures that change the availability, price, and visibility of plant-based meals.

Background: Haemorrhagic shock is the leading cause of preventable death among trauma patients. Early detection of severe haemorrhage is essential for initiating timely resuscitation and mobilizing resources for massive transfusion (MT) protocols and damage control procedures. This study aimed to assess the predictive value of prehospital haemoglobin (Hb) levels for the need for transfusion at admission, the presence of haemorrhagic shock (HS), and the necessity for MT or haemostatic surgery.
