Influence of cementless hip stems on femoral cortical strain pattern depending on their extent of porous coating [PDF]

, 2012
The extent of porous coating of cementless total hip stems is held responsible for radiological periprosthetic changes, the rate of thigh pain, and even its long-term success.

Nasal Mucosa‐Derived Extracellular Vesicles as a Systemic Antiaging Intervention

Advanced Science, EarlyView.
This study shows that nasal mucosa‐derived extracellular vesicles (nmEVs) exert systemic anti‐ageing effects in mice by restoring circadian rhythm, suppressing cellular senescence, and improving cognitive function. In aged human bone marrow mesenchymal stem cells, nmEVs reverse senescence‐associated phenotypes and reactivate core clock gene expression.

The first Neanderthal remains from an open-air Middle Palaeolithic site in the Levant [PDF]

, 2017
The late Middle Palaeolithic (MP) settlement patterns in the Levant included the repeated use of caves and open landscape sites. The fossil record shows that two types of hominins occupied the region during this period - Neandertals and Homo sapiens ...

Designer Solid Self‐Emulsifying Nanovaccines Enable Dual Modulation of Dendritic Cells and T Cells for Potent Antitumor Immunity

Advanced Science, EarlyView.
A solid self‐emulsifying (SSE) platform is loaded with peptide antigens and CpG to form the SSE vaccine. An ApoE‐enriched corona promotes dendritic cell internalization, enabling antigen presentation and T cell activation. Squalene from the SSE also sensitizes T cells by promoting lipid raft formation.

Non-alcoholic fatty liver disease connections with fat-free tissues: A focus on bone and skeletal muscle [PDF]

, 2017
The estimates of global incidence and prevalence of non-alcoholic fatty liver disease (NAFLD) are worrisome, due to the parallel burden of obesity and its metabolic complications. Indeed, excess adiposity and insulin resistance represent two of the major

Identification and Mechanisms of Osteocyte Subsets Involved in the Pathological Progression of Osteoporosis

Advanced Science, EarlyView.
Osteocyte heterogeneity in bone remains poorly understood. This study identifies six distinct osteocyte subsets in mice, revealing a key subpopulation (BHR‐Ocys) that drives bone loss in osteoporosis. BHR‐Ocys promote osteoclast‐mediated resorption via a novel Sema5a‐Plxna1 signaling axis.
