Generalized cell phenotyping for spatial proteomics with language-informed vision models.

We present a novel approach to cell phenotyping for spatial proteomics that addresses the challenge of generalization across diverse datasets with varying marker panels. Our approach utilizes a transformer with channel-wise attention to create a language-informed vision model; this model's semantic understanding of the underlying marker panel enables it to learn from and adapt to heterogeneous datasets. Leveraging a curated, diverse dataset with cell type labels spanning the literature and the NIH Human BioMolecular Atlas Program (HuBMAP) consortium, our model demonstrates robust performance across various cell types, tissues, and imaging modalities.

Clinical Characteristics of Proliferative Diabetic Retinopathy and Outcome of Pars Plana Vitrectomy in Proliferative Diabetic Retinopathy.

Background: Proliferative diabetic retinopathy is a leading cause of blindness among people with diabetes. The study aimed to assess the clinical characteristics of proliferative diabetic retinopathy and outcome of pars plana vitrectomy in Proliferative diabetic retinopathy.

Methods: A prospective study was conducted from September 2019 to December 2021 among consecutive cases of proliferative diabetic retinopathy who underwent pars plana vitrectomy at a tertiary eye care center.

Patterns of Macular Edema in Branch Retinal Vein Occlusion Diagnosed by Optical Coherence Tomography.

Introduction: Branch Retinal vein occlusion is the most common retinal vascular disease after diabetic retinopathy in elderly populations.

Objectives: To describe morphological patterns of macular edema in branch retinal vein occlusion using optical coherence tomography.

Materials And Methods: It is a hospital based; descriptive, cross-sectional study.

Stability and reactivity of alkylidene dihydropyridines.

Alkylidene dihydropyridines (ADHPs) are electron-rich nucleophilic intermediates that can be readily prepared by dearomatization of 4-alkylpyridines using chloroformate reagents and mild base. Their stability and reactivity can be tuned with the chloroformate reagent used as evidenced by NMR chemical shifts and oxidation potentials. ADHPs prepared with ethyl, allyl and trichloroethyl chloroformate undergo decomposition under an oxygen atmosphere at different rates (ethyl > allyl > trichloroethyl), predominantly to the corresponding 4-acylpyridine.

Adiabat-to-Diabat Angle in Seam Space: Renner-Teller-Type and Pseudo-Jahn-Teller-Type Problems.

In this study, we examine the adiabat-to-diabat (ATD) angles for trajectories in 2-dimensional vibrational subspace of the seam space of two degenerate states. In circulating around the tangential touching degeneracy center, the ATD angle is changed by or 0, similar to the Renner-Teller problem and the pseudo-Jahn-Teller problem, respectively. These ATD angle profiles may be indistinguishable from those of circulating multiple conical intersections or a pseudo-Jahn-Teller center.
