Planting native flora is a popular conservation strategy for pollinators. When searching for native plants, consumers may encounter cultivars of native plants, which can have different phenotypic traits than plants found in wild populations ("wild-type native plants"). Previous research evaluating pollinator visitation to wild-type native plants and native cultivars has yielded mixed results, in terms of whether their visitation rates are similar or distinct.

There is growing consensus in the Alzheimer's community that combination therapy will be needed to maximize therapeutic benefits through the course of the disease. However, combination therapy raises complex questions and decisions for study sponsors, from preclinical research through clinical trial design to regulatory, statistical, and operational considerations. In January 2024, the Alzheimer's Drug Discovery Foundation convened an expert advisory board to discuss the key considerations in each of these areas.

Objective: Selective serotonin reuptake inhibitors (SSRIs) are the first choice in pharmacotherapy for children and adolescents with obsessive-compulsive disorder (OCD). SSRI-trials for pediatric OCD have never been investigated using individual participant data (IPD), which is crucial for detecting patient-level effect modifiers. Here, we performed an IPD meta-analysis on the efficacy of SSRIs compared to placebo, and a meta-regression on baseline patient characteristics which might modify efficacy.

Immune checkpoint inhibitors (ICIs) show limited success in treating pancreatic ductal adenocarcinoma (PDAC), largely due to immune evasion mechanisms, including downregulating expression of major histocompatibility complex class I (MHC-I). Our retrospective analysis demonstrated that smoking - a state of elevated CO exposure - is correlated with increased MHC I expression in pancreatic tumors. Here we tested our hypothesis that introducing exogenous CO augments the anti-cancer effects of immunotherapy.

Tumor heterogeneity remains a formidable obstacle in targeted cancer therapy, often leading to suboptimal treatment outcomes. This study presents an innovative approach that harnesses controlled inflammation to guide neutrophil-mediated drug delivery, effectively overcoming the limitations imposed by tumor heterogeneity. By inducing localized inflammation within tumors using lipopolysaccharide, it significantly amplify the recruitment of drug-laden neutrophils to tumor sites, irrespective of specific tumor markers.

Preliminary Evidence for Perturbation-Based tACS-EEG Biomarkers of Gamma Activity in Alzheimer's Disease.

Int J Geriatr Psychiatry

January 2025

Precision Neuroscience & Neuromodulation Program, Gordon Center for Medical Imaging, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Background: Alzheimer's disease (AD) is characterized by impaired inhibitory circuitry and GABAergic dysfunction, which is associated with reduced fast brain oscillations in the gamma band (γ, 30-90 Hz) in several animal models. Investigating such activity in human patients could lead to the identification of novel biomarkers of diagnostic and prognostic value. The current study aimed to test a multimodal "Perturbation-based" transcranial Alternating Current Stimulation-Electroencephalography (tACS)-EEG protocol to detect how responses to tACS in AD patients correlate with patients' clinical phenotype.
