The Ultra-Orthodox (Haredi) Jewish Community in New York City suffered significantly during the COVID-19 pandemic. The community came under public scrutiny after some members staunchly advocated for reopening of certain resources central to community culture. This study utilizes qualitative techniques to examine the perspectives of medical providers that serve the Haredi community toward pandemic-related government sanctions, as well as the resultant effects the restrictions had on community receipt of healthcare.

The Pacific oyster Crassostrea gigas is rich in taurine, a conditionally essential amino acid functioning in anti-oxidation, anti-inflammation, anti-aging, osmoregulation, and neuromodulation. Breeding oyster varieties with enhanced taurine content is significant to meet people's demand for high-quality oysters. In the present study, polymorphisms in the oyster cysteamine dioxygenase (CgADO) gene that encodes the central enzyme of the cysteamine pathway for taurine synthesis were investigated, and their association with taurine content was assessed in the Changhai (CH) and Qinhuangdao (QHD) populations.

Community violence is a major cause of injury and death in the USA. Empirical studies have identified that some place-based interventions of urban private places, such as remediations of vacant lots and buildings, are associated with reductions in community violence in surrounding areas. The aim of this study was to examine whether routine maintenance and repair of urban public places (e.

Background: Flat epithelial atypia (FEA), a rare breast proliferative lesion, is often diagnosed following core biopsy (CB) of mammographic microcalcifications. In the prospective multi-institution TBCRC 034 trial, we investigate the upgrade rate to ductal carcinoma in situ (DCIS) or invasive cancer following excision for patients diagnosed with FEA on CB.

Patients And Methods: Patients with a breast imaging reporting and data system (BI-RADS) ≤ 4 imaging abnormality and a concordant CB diagnosis of FEA were identified for excision.

Histiocytic sarcoma (HS) is a rare yet lethal malignancy with no established standard of care therapies. A lack of pre-clinical models limits our understanding of HS pathogenesis and identification of therapeutic targets. Canine HS shares multiple clinical and genetic similarities with human HS, supporting its use as a unique translational model.

Background: Esophageal cancer (ESC) is an aggressive disease which often presents at an advanced stage. Despite trimodal therapy, 40-50% patients can develop metastatic disease by 18 months. Identification of patients at risk for metastatic spread is challenging with need for improved prognostication.

Burn wounds are challenging to treat due to considerable tissue damage and fluid loss. Creating wound dressings from natural and biological materials makes it possible to treat wounds and promote rapid epithelialization to speed healing and restore skin function. As a result, the ability of a collagen scaffold (Col) made from rainbow trout (Oncorhynchus mykiss) and putative bioactive phytochemical components from a Sargassum glaucescens (S.

Purpose: The study aimed to compare the diagnostic accuracy of Ga-DOTA-FAPI-04 (Ga-FAPI) and F-FDG PET/CT for peritoneal carcinomatosis (PC) in patients with various types of cancer.

Methods: The study enrolled 113 patients with suspected peritoneal malignancy, each of whom underwent Ga-FAPI and F-FDG PET/CT scans. Lesions in all patients were confirmed through pathology or radiological follow-up.

Objectives: To improve preoperative diagnostic accuracy of struma ovarii by retrospectively reviewing magnetic resonance (MR) findings. It is beneficial to choose the most appropriate surgical modality for the patient.

Methods: We retrospectively reviewed the clinical course and MR characteristics of 52 patients who were diagnosed postoperatively with struma ovarii, pathologically, from two institutions.

Background: Glial cells exhibit distinct transcriptional responses to β-amyloid pathology in Alzheimer's disease (AD). While sophisticated single-cell based methods have revealed heterogeneous glial subpopulations in the human AD brain, the histological localization of these multicellular responses to AD pathology has not been fully characterized due to the loss of spatial information. Here, we combined spatial transcriptomics (ST) with immunohistochemistry to explore the molecular mechanisms in the neuritic plaque niche.

Background: Numerous studies have highlighted the role of oxidative stress in Alzheimer's disease (AD) development. Yet, the alignment of systemic and central oxidative stress biomarkers is unclear across diverse populations in the AD continuum. This study aims to assess protein damage levels in plasma and cerebrospinal fluid (CSF) within the AD continuum.

Background: Heterogeneity in the progression of clinical dementia poses a significant challenge, impeding the effectiveness of current therapies for Alzheimer's disease (AD). To decipher the molecular mechanisms governing heterogeneity in AD progression that remains a critical knowledge gap precluding rational therapeutic design, we investigated the biochemical and biophysical properties of tau present in the inferior temporal gyrus (ITG) and prefrontal cortex (PFC) brain regions of AD patients who had varying disease progression rates. To explore gene expression changes in the ITG which are associated with tau pathology and cognitive decline, we used RNA sequencing for molecular characterization of patients displaying tau and clinical heterogeneity.

Background: The transfer of mitochondrial DNA into the nuclear genomes of eukaryotes (Numts) has been linked to lifespan in non-human species and recently demonstrated to occur in rare instances from one human generation to the next.

Method: Here we investigated numtogenesis dynamics in humans in two ways. First, we quantified Numts in 1,187 post-mortem brain and blood samples from different individuals.

Background: Clinicopathological studies of Alzheimer's disease (AD) have demonstrated that synaptic or neuronal loss and clinical cognitive decline do not reliably correlate with fibrillar amyloid burden. We created a transgenic mouse model overexpressing Dutch (E693Q) mutant human amyloid precursor protein (APP) driven by the pan-neuronal Thy1 promoter. Accumulation of APP carboxyl-terminal fragments was observed in the brains of these mice, which develop an impaired learning phenotype directly proportional to brain oAβ levels.

Background: How tauopathy disrupts direct entorhinal cortex (EC) inputs to CA1 and their plasticity is understudied, despite its critical role in memory. Moreover, dysfunction of lateral EC (LEC) input is less clear, despite its relevance to early Alzheimer's disease pathogenesis. Here we examined how tau impacts long-term potentiation (LTP) of LEC→CA1 input in a transgenic model of tauopathy.

Background: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by hallmark pathologies that affect many brain regions, including the cellular microenvironment with the hippocampus, ultimately leading to profound deficits in cognition. Surprising recent work has shown that factors in the systemic environment regulate the hippocampal cellular niche; age-associated blood-borne factors exacerbate brain aging phenotypes, whereas youth-associated blood-borne factors, including tissue inhibitor of metalloproteinases 2 (TIMP2), reverse or ameliorate features of brain aging. As aging serves as the major risk factor for AD, and recent work shows that systemic factors can regulate AD pathology, we sought to characterize mechanisms by which the systemic environment regulates CNS phenotypes relevant to AD pathology through changes in neuroinflammation.

Alzheimers Dement

December 2024

Weill Cornell Medicine, New York, NY, USA.

Background: The strongest genetic risk factors for AD include the e4 allele of APOE and the R47H point mutation in the TREM2 receptor. TREM2 is required for the induction of a disease-associated microglia (DAM) signature and microglial neurodegenerative phenotype (MGnD) in response to disease pathology, signatures which both include APOE upregulation. There is currently limited information regarding how the TREM2-APOE pathway ultimately contributes to AD risk, and downstream mechanisms of this pathway are unknown.

Humans perceive discrete events such as "restaurant visits" and "train rides" in their continuous experience. One important prerequisite for studying human event perception is the ability of researchers to quantify when one event ends and another begins. Typically, this information is derived by aggregating behavioral annotations from several observers.
