Personalizing the management of neovascular age-related macular degeneration (nAMD) poses significant challenges for practicing retina specialists and their patients. This commentary addresses some of these complexities, particularly those that arise in the context of an expanding array of intravitreal agents targeting vascular endothelial growth factor (VEGF) and related retinal disease targets. Many of these newer agents approved by the Food and Drug Administration (FDA) for the treatment of nAMD have labeling that indicates that they can provide non-inferior visual outcomes when compared head-to-head with previously available treatments and can be used at significantly extended dosing intervals in some patients.

Background/objectives: This paper examines hunger over time to analyze how food insecurity is impacted by reduced income, including household funding from the government. Federal policies and community-based programs have the ability to prevent increases in food insecurity, particularly for populations that have risk factors, such as households with children; single-parent households; low-income households, especially those in rural areas; Black and Hispanic households; and, households experiencing economic hardships.
Methods: This study is bas ed on a cross-sectional survey that was administered in 2018 and 2019 to food pantry clients, an already food insecure population accessing resources, in Eastern Massachusetts.

One of the key factors that contribute to tumor progression and resistance is the immunosuppressive microenvironment of the tumor. CD200 is a recently identified cell surface glycoprotein recognized as an important molecule in breast cancer for its versatile modulation of the immune response via its receptor, CD200R. The interaction between CD200 and CD200R suppresses the immune activities against tumor cells and allows them to be undetected and, in doing so, to escape from the destructive capability of the immune cells.

Prime editing (PE) is a CRISPR-based tool for genome engineering that can be applied to generate human induced pluripotent stem cell (hiPSC)-based disease models. PE technology safely introduces point mutations, small insertions, and deletions (indels) into the genome. It uses a Cas9-nickase (nCas9) fused to a reverse transcriptase (RT) as an editor and a PE guide RNA (pegRNA), which introduces the desired edit with great precision without creating double-strand breaks (DSBs).

The rapidly growing glycoscience has boosted the research on the synthesis of glycans and their conjugates, which are centered on the stereoselective formation of glycosidic bonds. Compared to the mainstream acid-promoted glycosylation method that undergoes the S1 type mechanism, the basic/neutral conditions give better stereo control via the S2 mechanism. Anomeric hydroxyl group transformation, whether to form glycosidic bonds directly or to install a leaving group for later glycosylation, is key to carbohydrate synthesis, and the strategies in the stereo control of these reactions under basic/neutral conditions are summarized in this review.

Background: Genetic discontinuity represents abrupt breaks in genomic identity among species. Advances in genome sequencing have enhanced our ability to track and characterize genetic discontinuity in bacterial populations. However, exploring the degree to which bacterial diversity exists as a continuum or sorted into discrete and readily defined species remains a challenge in microbial ecology.

Purpose: PSMA-PET is a reference standard examination for patients with prostate cancer, but even using recently introduced digital PET detectors image acquisition with standard field-of-view scanners is still in the range of 20 min. This may cause limited access to examination slots because of the growing demand for PSMA-PET. Ultra-fast PSMA-PET may enhance throughput but comes at the cost of poor image quality.

Three monoclonal antibodies directed against specific forms of the amyloid-β (Aβ) peptide have been granted accelerated or traditional approval by the FDA as treatments for Alzheimer disease, representing the first step towards bringing disease-modifying treatments for this disease into clinical practice. Here, we review the detection, underlying pathophysiological mechanisms and clinical implications of amyloid-related imaging abnormalities (ARIA), the most impactful adverse effect of anti-Aβ immunotherapy. ARIA appears as regions of oedema or effusions (ARIA-E) in brain parenchyma or sulci or as haemorrhagic lesions (ARIA-H) in the form of cerebral microbleeds, convexity subarachnoid haemorrhage, cortical superficial siderosis or intracerebral haemorrhage.

Myeloid cells play a crucial dual role in cancer progression and response to therapy, promoting tumor growth, enabling immune suppression, and contributing to metastatic spread. The ability of these cells to modulate the immune system has made them attractive targets for therapeutic strategies aimed at shifting their function from tumor promotion to fostering antitumor immunity. Therapeutic approaches targeting myeloid cells focus on modifying their numbers, genetics, metabolism, and interactions within the tumor microenvironment.
