165 nm), possibly Syn oligomers. The Syn micellar-like aggregates formed at pH 7 solutions seem to be active species and to have a role in this protein aggregation mechanism.l-lactate dehydrogenases (LDHs) has been widely studied for their ability to reduce 2-keto acids for the production of 2-hydroxy acids, whereby 2-hydroxybutyric acids (2-HBA) is among the most important fundamental building blocks for synthesizing pharmaceuticals and biodegradable materials. However, LDHs usually show low activity towards 2-keto acids with longer side chain such as 2-oxobutyric acid (2-OBA). Here rational engineering of the Plasmodium falciparum LDH loop with residue involved in the catalytic proton transfer was initially studied. By combining homology alignment and structure-based design approach, we found that changing the charge characteristics or hydrogen bond network interactions of this loop could improve enzymatic catalytic activities and stabilities towards 2-OBA. UCL-TRO-1938 purchase UCL-TRO-1938 purchase Compared with wild type, variant N197Dldh showed 1.15 times higher activity and 2.73 times higher Kcat/Km. The half-life of variant N197Dldh at 40 °C increased to 77.9 h compared with 50.4 h of wild type. Furthermore, asymmetric synthesis of (S)-2-HBA with coenzyme regeneration revealed 95.8 g/L production titer within 12 h for variant N197Dldh, 2.05 times higher than using wild type. Our study indicated the importance of loop with residues involved in the catalytic proton transfer process, and the engineered LDH would be more suitable for (S)-2-HBA production.Studying the development of unique materials from sustainable and renewable resources has gained increasing concern due to the depletion of fossil resources. Chitosan and its derivatives have been considered as versatile candidates for preparing attractive materials. The fabrication of chitosan/calcium phosphate composite compounds has received much attention for the development of numerous promising products in different fields. In this short review, recent preparation strategies for chitosan/calcium phosphate composites such as freeze casting, vacuum-assisted filtration, and biomimetic mineralization were discussed. The review presented their advances for diverse applications such as bone tissue engineering implants, drug delivery, wound healing, dental caries, as well adsorption of organic and heavy metals from polluted water. link2 The challenges and future perspectives for the application of chitosan/calcium phosphate materials in biomedical and environmental applications were also involved in this review article.A novel and environmentally friendly lignin-based surfactant sodium lignosulfonate (SLS) modified layered double hydroxide (LDH) flame retardant (LDH-LS) was fabricated via co-precipitation method, and subsequently incorporated into polypropylene (PP) matrix to obtain the PP and LDH-LS composites (PP/LDH-LS) by melt blending method. The XRD, FT-IR and XPS results indicated that SLS had successfully modified LDH by adsorbing on the surface of the LDH nanosheet. The WCA and SEM results revealed that the hydrophobic property of LDH-LS had been evidently improved, and it displayed a more homogeneous dispersion than virgin LDH in the PP matrix. link2 Furthermore, cone calorimetry tests (CCT) illustrated that the peak heat release rate (PHRR), total heat release (THR), and total smoke release (TSR) of PP/LDH-LS composites exhibited declines of 62.9%, 25.1%, and 43.3% compared with those of Neat PP, respectively. Besides, the PP/LDH-LS achieved a LOI value of 29.4% and a UL-94 V-0 rating, whereas the PP/LDH showed only a LOI value of 25.2% and a UL-94 V-2 rating at 20 wt% loading. These improvements of flame retardant properties can be attributed to that the well-dispersed LDH-LS and synergistic flame retardancy between LDH and SLS.We isolated and purified a pectin from Portulaca oleracea L. (P. oleracea), and analysed its structure by high-performance size exclusion chromatography (HPSEC), high-performance liquid chromatography (HPLC), gas chromatograph-mass spectrometer (GC-MS), fourier transform infrared spectroscopy (FT-IR), and 1H, 13C nuclear magnetic resonance spectroscopy (NMR). The data indicated that this pectin (designated as POPW-HG) was a linear non-esterified homogalacturonan, which is unique in plants; its molecular weight was around 41.2 kDa. Meanwhile, POPW-HG as an adjuvant was evaluated in the mice immunized with OVA subcutaneously. UCL-TRO-1938 purchase OVA-specific antibody titres from the sera of immunized mice were tested by ELISA. It showed that POPW-HG significantly enhanced OVA-specific antibody titres (IgG, IgG1, and IgG2b) (p less then 0.05) in a dose-dependent manner in the OVA-immunized mice, preliminarily indicating POPW-HG could increase an antibody response, Th1 and Th2 immune response. In addition, the ratio of IgG1/IgG2b suggested POPW-HG induced a Th2-biased response in the OVA-immunized mice. The results demonstrated POPW-HG could be a potential adjuvant candidate in vaccines.Hematin has been used as an alternative enzyme catalyst to horseradish peroxidase (HRP) due to its iron-containing activity center. Although hematin and it derivatives have been widely used for polymerization of phenol/analine compounds, it has some drawbacks such as the limited solubility and reaction only at high pH condition. Herein, we report a nanosized biomimetic catalyst, hematin-decorated polyamidoamine dendrimer (G3.0-He) that can effectively catalyze the in situ hydrogelation of phenol-conjugated polymers under neutral pH condition. We demonstrate that G3.0-He particles are smaller than 100 nm and have excellent enzyme-mimetic functions. Interestingly, the nanosized catalyst is not inactivated at high H2O2 concentration. Compared to pure hematin, G3.0-He has significantly higher dispersion in acidic and neutral media, and preserves the percentage of survival of fibroblasts over 90%. Notably, G3.0-He possesses an exquisite HRP-mimicking activity in gelation of gelatin derivative with phenolic hydroxyl (tyamine) moieties under mild physiological conditions. The in vitro study demonstrated that Gel-Tyr hydrogel by G3.0-He catalyzed reaction had excellent cytocompatibility and an excellent scaffold for adhesion to fibroblast cells. Therefore, the designed minimalistic G3.0-He catalyst could serve as an effective catalytic alternative for HRP enzyme in the preparation of biomedical hydrogels.This work aimed to evaluate the potential of chitosan/cellulose nanocrystals (CNC) films to be used as active pads for meat packages to prolong its shelf-life and preserve its properties over time. Several CNC concentrations (5, 10, 25, and 50 wt%) were tested and the films were produced by solvent casting. link2 The developed samples were characterized by ATR-FTIR, TGA, FESEM, and XRD. The transparency, antimicrobial, barrier and mechanical properties were also assessed. Finally, the films' ability to prolong food shelf-life was studied in real conditions using chicken meat. CNC incorporation improved the thermal stability and the oxygen barrier while the water vapor permeability was maintained. UCL-TRO-1938 purchase An enhancement of mechanical properties was also observed by the increase in tensile strength and Young's modulus in chitosan/CNC films. These films demonstrated bactericidal effect against Gram-positive and Gram-negative bacteria and fungicidal activity against Candida albicans. Lastly, chitosan-based films decreased the growth of Pseudomonas and Enterobacteriaceae bacteria in meat during the first days of storage compared to commercial membranes, while chitosan/CNC films reduced the total volatile basic nitrogen (TVB-N), indicating their efficiency in retarding meat's spoilage under refrigeration conditions. link3 This work highlights the great potential of natural-based films to act as green alternatives for food preservation.Entamoeba histolytica phosphoserine phosphatase (EhPSP), a regulatory enzyme in the serine biosynthetic pathway, is also a structural homolog of cofactor-dependent phosphoglycerate mutase (dPGM). However, despite sharing many of its catalytic residues with dPGM, EhPSP displays no significant mutase activity. In the current work, we determined a crystal structure of EhPSP in complex with 3-PGA to 2.5 Å resolution and observed striking differences between the orientation of 3-PGA bound to EhPSP and that to its other homologous structures. link2 We also performed computational modeling and simulations of the intermediate 2,3-bisphosphoglyceric acid into the active site of EhPSP to better understand its mechanistic details. Based on these results and those of a similar study with the dPGMs from E. coli and B. pseudomallei, the affinity of EhPSP for 2,3-BPG was concluded to be lower than those of the other proteins. Moreover, a different set of 2,3-BPG interacting residues was observed in EhPSP compared to dPGMs, with all of the crucial interacting residues of dPGMs either missing or substituted with weakly interacting residues. link3 This study has expanded our understanding, at the structural level, of the inability of EhPSP to catalyze the mutase reaction and has strengthened earlier conclusions indicating it to be a true phosphatase.The aim of this manuscript is to describe knowledge gaps in the literature, future directions, and emerging applications of gait and balance analysis in spine surgery with regard to functional outcomes measurement. Functional outcome measurement has been established as a useful clinical and research investigational tool in musculoskeletal disease. Evidence currently supports its use in the diagnosis, treatment, and outcome measurement of multiple musculoskeletal disease states, including spinal disease, and its usefulness continues to grow as literature develops. Gait and balance analysis has proven to be broadly applicable, but most clinicians remain unfamiliar and untrained in its usage. The logistical and communication barriers are also described with the potential solutions that are on the near horizon of research. This article describes our methodology for improving conveyance of functional outcome measures in spine surgery. link3 Additionally, we provide a case example of an adult patient with spinal deformity who is examined pre and post operatively using our methodology.Alcohol tolerance refers to a lower effect of alcohol with repeated exposure. link3 Although alcohol tolerance has been historically included in diagnostic manuals as one of the key criteria for a diagnosis of alcohol use disorder (AUD), understanding its neurobiological mechanisms has been neglected in preclinical studies. In this mini-review, we provide a theoretical framework for alcohol tolerance. We then briefly describe chronic tolerance, followed by a longer discussion of behavioral and neurobiological aspects that underlie rapid tolerance in rodent models. Glutamate/nitric oxide, γ-aminobutyric acid, opioids, serotonin, dopamine, adenosine, cannabinoids, norepinephrine, vasopressin, neuropeptide Y, neurosteroids, and protein kinase C all modulate rapid tolerance. Most studies have evaluated the ability of pharmacological manipulations to block the development of rapid tolerance, but only a few studies have assessed their ability to reverse already established tolerance. Notably, only a few studies analyzed sex differences.
