Background: Low-density lipoprotein receptor-related protein-2 (LRP2), also called megalin, is a multi-ligand receptor of the LDL receptor gene family mediating reabsorption of ligands like Apo-A1. Type 2 diabetes mellitus (T2DM) may possibly disrupt megalin functions as it is found to be regulated by insulin. This might cause cardiovascular complications due to derangement in lipoprotein metabolism.

Although the precise pathophysiology of MIS-C is uncertain, it is thought to be due to immune dysregulation occurring after recovery from acute infection.
Purpose: Our study aimed to analyze the clinical spectrum, laboratory parameters, imaging characteristics, treatment strategies, and short-term outcomes of children with a diagnosis of MIS-C.
Transition metal chalcogenides (TMCs) are a large family of 2D materials that are currently attracting intense interest.

Case Series: Fourteen systemically healthy patients presenting with 35 RT1 recession defects were treated with A-PRF + CAF. Recession height (RH), recession width (RW), probing pocket depth (PPD), clinical attachment level (CAL), keratinized tissue height (KTH), and width of attached gingiva (WAG) were measured at baseline, 3, and 6 months.
Doping of materials beyond the dopant solubility limit remains a challenge, especially when spatially nonuniform doping is required. In 2D materials with a high surface-to-volume ratio, such as transition metal dichalcogenides, various post-synthesis approaches to doping have been demonstrated, but full control over spatial distribution of dopants remains a challenge. A post-growth doping of single layers of WSe is performed by adding transition metal (TM) atoms in a two-step process, which includes annealing followed by deposition of dopants together with Se or S.

By analyzing the structural stability of various MLi ( = 0-10) clusters, it is revealed that a tetrahedron-shaped MLi Zintl cluster is found to be highly stable. Our study on the interaction between the lithiated clusters and CNT illustrates that the charge transfer from the former to latter plays a pivotal role in stabilizing these nanocomposites.

However, it does not work for graphene or h-BN, as the dopant atoms prefer clustering on the surface of the material instead of getting integrated into the atomic network. Using extensive first-principles calculations, we show that counterintuitively most transition metal (TM) atoms can be embedded into the atomic network of the pristine molybdenum dichalcogenides (MoDCs) upon atom deposition at moderate temperatures either as interstitials or substitutional impurities, especially in MoTe, which has the largest spacing between the host atoms.

By employing first principles density functional calculations, we investigated an α-MnO compound with a tunnel framework, which provides an eminent platform to alter the intrinsic antiferromagnetic (AFM) to ferromagnetic (FM) ordering, through the introduction of chemical or mechanical tensile strain. Our calculations further showed that the strength of FM ordering increases until 10% triaxial tensile strain. Since long range FM ordering is induced, it is realized to be superior as compared to the experimentally observed short-range FM ordering in oxygen-deficient compound.

The pristine NW is found to be metallic and its local structure and physical properties can be tuned by doping of iodine atoms. This doping increases the number of Mo-Mo bonds in the NW, thus, Mo4 tetrahedra are initially fused to the Mo6 octahedron, and then, to the Mo8 dodecahedron.
