When squamous cell carcinoma necessitates mandibular resection, the resultant defect can be complex. An osteocutaneous fibula free flap is an effective reconstruction option, typically supplied by the peroneal artery for both the fibula and skin flap. In this case report, an anatomical variation was found: the skin paddle was supplied by soleus musculocutaneous perforators of the posterior tibial artery, whereas the fibula was supplied by the peroneal artery.

Introduction: Alzheimer's disease (AD) and other tauopathies are characterized by intracellular aggregates of microtubule-associated protein tau that are actively released and promote proteopathic spread. Microglia engulf pathological proteins, but how they endocytose tau is unknown.

Methods: We measured endocytosis of different tau species by microglia after pharmacological modulation of macropinocytosis or clathrin-mediated endocytosis (CME) or antagonism/genetic depletion of known tau receptors heparan-sulfate proteoglycans (HSPGs) and low-density lipoprotein receptor-related protein 1 (LRP1).

Aims/hypothesis: Insulin resistance and compensatory hyperinsulinaemia are core features leading to beta cell failure in youth-onset type 2 diabetes. Insulin clearance (IC) is also a key regulator of insulin concentrations, but few data exist on IC in youth-onset type 2 diabetes. In a secondary analysis of our Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) randomised clinical trial, we investigated potential sex-, race-, ethnicity- and treatment-related differences in IC in youth-onset type 2 diabetes and aimed to identify metabolic phenotypes associated with IC at baseline and in response to metformin, metformin plus a lifestyle intervention, and metformin plus rosiglitazone.

Article Synopsis
  • Diffuse large B-cell lymphoma (DLBCL) is a serious type of cancer where the current treatment, R-CHOP, cures only about 60% of patients, prompting the need for improved therapies.
  • Researchers investigated the combination of the FDA-approved PDE4 inhibitor roflumilast with R-CHOP in high-risk, treatment-naïve DLBCL patients, which showed safety and encouraging outcomes, with 70% of patients alive and disease-free at 44 months.
  • Initial results indicate that roflumilast could enhance cancer treatment by inhibiting certain cancer-related signals and may be especially effective for specific high-risk genetic subtypes of DLBCL, suggesting further testing is needed.

Structural covariance in brain anatomy is thought to reflect inter-regional sharing of developmental influences - although this hypothesis has proved hard to causally test. Here, we use neuroimaging in humans and mice to study sex-differences in anatomical covariance - asking if regions that have developed shared sex differences in volume across species also show shared sex difference in volume covariance. This study design illuminates both the biology of sex-differences and theoretical models for anatomical covariance - benefitting from tests of inter-species convergence.

Article Synopsis
  • Exposure to crystalline silica leads to silicosis, a condition characterized by progressive fibrosis, with fibroblasts playing a critical role in this process.
  • Research highlights that activated fibroblasts influence the conversion of group 2 innate lymphoid cells (ILC2) to group 1 (ILC1) during silicosis progression through the interleukin-18 (IL-18) signaling pathway.
  • The study reveals that inhibiting Notch3 signaling in fibroblasts can slow down the progression of pulmonary fibrosis, suggesting new immune-modulatory mechanisms and potential treatment targets for lung diseases linked to fibrosis.

Dynamic multilayered control of mA RNA demethylase activity.

Proc Natl Acad Sci U S A

November 2024

Division of Hematology and Medical Oncology, Mays Cancer Center, University of Texas Health Science Center San Antonio, San Antonio, TX 78229.

Article Synopsis
  • - RNA can be chemically modified through methylation, particularly at the N6-methyladenosine (mA) site on mRNA, which is regulated by the methyltransferase complex and removed by demethylases FTO and ALKBH5.
  • - The outcome of mA-marked mRNA can either lead to its degradation or stabilization/translation, influenced largely by its interaction with specific proteins known as YTH domain-containing proteins.
  • - New insights show that factors like metabolism and posttranslational modifications can affect the functioning and location of FTO and ALKBH5, indicating that mA methylation is a dynamic process that warrants further exploration in cancer and other health conditions.

Relationship between MRI brain-age heterogeneity, cognition, genetics and Alzheimer's disease neuropathology.

EBioMedicine

November 2024

AI(2)D, Center for AI and Data Science for Integrated Diagnostics, and Center for Biomedical Image Computing and Analytics, University of Pennsylvania, Philadelphia, PA, USA. Electronic address:

Background: Brain ageing is highly heterogeneous, as it is driven by a variety of normal and neuropathological processes. These processes may differentially affect structural and functional brain ageing across individuals, with more pronounced ageing (older brain age) during midlife being indicative of later development of dementia. Here, we examined whether brain-ageing heterogeneity in unimpaired older adults related to neurodegeneration, different cognitive trajectories, genetic and amyloid-beta (Aβ) profiles, and to predicted progression to Alzheimer's disease (AD).
