Summary: The use of polysaccharides with good film-forming properties in food packaging systems is a promising area of research. Xanthan gum (XG), an extracellular polysaccharide, has many industrial uses, but XG-based polymer films have some disadvantages, such as poor mechanical properties and high hydrophilic features. This study aimed to stabilize a XG matrix by cross-linking it with different compounds below the freezing point of the reaction mixture. XG-based cryogels with improved physicochemical properties were successfully prepared using the cryogelation technique.

Summary: Crosslinked chitosan hydrogels were synthesized through ionic and covalent interactions using tripolyphosphate (TPP) and formaldehyde (CH2O). An experimental design was used to predict physiochemical properties, revealing that chitosan concentration affects the point of zero charge, crosslinker concentration influences the swelling ratio, and contact time has the most significant effect on equilibrium water content.

Summary: In this study, a large molecular size bisphenol A ethoxylate diacrylate (BPA) was used to crosslink poly(ethylene glycol) methyl ether acrylate (PEGMEA) via UV polymerization for efficient CO2 capture. The microstructure of the membrane was tailored by adjusting the ratio of the two prepolymers, resulting in optimized microstructures with suitable mesh size and PEO sol content. The optimum membrane achieved a high CO2 permeability of 1711 Barrer and long-term stability under 15 atm, overcoming the tradeoff between gas permeability and high-pressure-resistance capacity.

Summary: Polyurethane hydrogels are widely used in various fields due to their durability, flexibility, and biocompatibility. In this study, polyurethane-based hydrogels were prepared using polyethylene glycol and a novel lactose monomer. It was found that the swelling of the hydrogels was driven by the hydrophilicity of the lactose units. Sulfation of the lactose rings resulted in high-swelling polyelectrolyte hydrogels. Furthermore, the effects of PEG molecular weight, degree of crosslinking, and sulfation on the swelling of the hydrogels were investigated.

Summary: The authors developed biocompatible nano-vesicles using graphene oxide (GO) for the targeted release of chlorambucil (CHL) drugs in cancer cells. GO sheets were functionalized with folic acid (FA) molecules to improve controlled release and loading efficiency of CHL. The drug was loaded onto the GO surface through pi-pi stacking and hydrophobic interactions. In vitro release studies showed a pH-dependent release, with faster release at lower pH.

Summary: This systematic review and meta-analysis found that the Attune knee system showed significant improvement in KSS scores and had favorable outcomes in terms of anterior knee pain and patellofemoral crepitus compared to the traditional PFC Sigma knee design. However, there were no significant differences in other outcome measures such as OKS and WOMAC scores, knee range of motion, patient satisfaction, and radiological outcomes.

Summary: The study aimed to compare and quantify the volume mismatch between the affected acetabulum and femoral head with the normal hip in patients with idiopathic developmental dysplasia of the hip (DDH). The results showed significant differences in acetabular index, acetabular volume, femoral head volume, and acetabular anterior sectoral angle between the affected and normal hips. The acetabulum was found to be significantly smaller on the affected side, and there was a negative correlation between the posterior acetabular sectoral angle and acetabular volume. These findings have important implications for the diagnosis and treatment of late-presenting DDH.

Summary: The study measured in-vivo thickness of available autograft options around the knee using MRI, finding moderate correlation between height and patellar thickness with semitendinosus tendon and patellar tendon thickness. Weak correlation was observed between other anthropometric variables and tendon thickness. MRI assessment of tendon sizes is a reliable method that can aid in preoperative planning and identifying patients at risk of having smaller tendons.
