Objective: To compare recognition of facial expression (FE) vs recognition of facial identity (FI) in posterior cortical atrophy (PCA), with the hypothesis that FE recognition would be relatively preserved in PCA.

Methods: In this observational study, FI and expression recognition tasks were performed by 194 participants in 4 groups, including 39 with Alzheimer disease (AD) (non-PCA), 49 with behavioral variant frontotemporal dementia (bvFTD), 15 with PCA, and 91 healthy controls. Between-group differences in test scores were compared.

Results: Patients with PCA performed worse than healthy controls in FI and emotion recognition tasks ( < 0.001 for all). Patients with PCA also performed worse than AD and bvFTD groups in FI recognition, with no difference in FE recognition.

Conclusions: Patients with PCA have relatively preserved FE recognition compared to FI recognition, as seen in affective blindsight.

Actinic keratosis with severe dysplasia and Bowen disease represent distinct pathways of intraepidermal squamous neoplasia: an immunohistochemical study.

Intraepidermal squamous neoplasia is a precursor to invasive cutaneous squamous cell carcinoma. The most common type of intraepidermal squamous neoplasia is actinic keratosis (AK), although there is compelling clinicopathological evidence of a second distinct pattern of squamous dysplasia termed Bowen disease (BD). The distinction between these pathways of dysplasia has been inconsistently delineated in the literature.

Role of TRIM29 in disease: What is and is not known.

Electronic address:

Tripartite motif-containing proteins (TRIMs), comprising the greatest subfamily of E3 ubiquitin ligases with approximately 80 members of this family, are widely distributed in mammalian cells. TRIMs actively participate in ubiquitination of target proteins, a type of post-translational modification associated with protein degradation and other functions. Tripartite motif-containing protein 29 (TRIM29), a member of the TRIM family, differs from other members of this family in that it lacks the RING finger structural domain containing cysteine and histidine residues that mediates DNA binding, protein-protein interactions, and ubiquitin ligase, at its N-terminus.

Objective: The aim of this study was to investigate the role of ferroptosis in the occurrence of postoperative cognitive dysfunction (POCD) using a mouse model and to elucidate whether electroacupuncture (EA) can improve POCD by suppressing ferroptosis via the transferrin receptor 1 (TFR1)-divalent metal transporter 1 (DMT1)-ferroportin (FPN) pathway.

Methods: The experiment involved three groups: the control group, the POCD group and the POCD + EA group. The POCD animal model was established using sevoflurane anesthesia and tibial fracture.

Following recent advances in post-thrombectomy stroke care, the role of neuroinflammation and neuroprotective strategies in mitigating secondary injury has gained prominence. Yet, while neuroprotection and anti-inflammatory agents have re-emerged in clinical trials, their success has been limited. The neuroinflammatory response in cerebral ischemia is robust and multifactorial, complicating therapeutic approaches targeting single pathways.

Beneficial mutualistic fungus Suillus luteus provided excellent buffering insurance in Scots pine defense responses under pathogen challenge at transcriptome level.

Background: Mutualistic mycorrhiza fungi that live in symbiosis with plants facilitates nutrient and water acquisition, improving tree growth and performance. In this study, we evaluated the potential of mutualistic fungal inoculation to improve the growth and disease resistance of Scots pine (Pinus sylvestris L.) against the forest pathogen Heterobasidion annosum.
