A genome-wide atlas of human cell morphology.

A key challenge of the modern genomics era is developing empirical data-driven representations of gene function. Here we present the first unbiased morphology-based genome-wide perturbation atlas in human cells, containing three genome-wide genotype-phenotype maps comprising CRISPR-Cas9-based knockouts of >20,000 genes in >30 million cells. Our optical pooled cell profiling platform (PERISCOPE) combines a destainable high-dimensional phenotyping panel (based on Cell Painting) with optical sequencing of molecular barcodes and a scalable open-source analysis pipeline to facilitate massively parallel screening of pooled perturbation libraries.

Discovery of (3-Phenylcarbamoyl-3,4-dihydro-2-pyrrol-2-yl)phosphonates as Imidazoline Receptor Ligands with Anti-Alzheimer and Analgesic Properties.

Imidazoline receptors (I-IRs) are altered in Alzheimer's disease (AD) patients and are associated with analgesia. I-IRs are not structurally described, and their pharmacological characterization relies on their modulation by highly affine ligands. Herein, we describe the synthesis of (3-phenylcarbamoyl-3,4-dihydro-2-pyrrol-2-yl)phosphonates endowed with relevant affinities for I-IRs in human brain tissues.

Engineering the Novel Extremophile Alga for High Lipid and High Starch Production as a Path to Developing Commercially Relevant Strains.

Microalgae offer a compelling platform for the production of commodity products, due to their superior photosynthetic efficiency, adaptability to nonarable lands and nonpotable water, and their capacity to produce a versatile array of bioproducts, including biofuels and biomaterials. However, the scalability of microalgae as a bioresource has been hindered by challenges such as costly biomass production related to vulnerability to pond crashes during large-scale cultivation. This study presents a pipeline for the genetic engineering and pilot-scale production of biodiesel and thermoplastic polyurethane precursors in the extremophile species .

Surgical management of an extensive nasal mass in an adolescent: insights from diagnostic imaging and histopathology.

A 17-year-old female presented with a mass in the right nasal fossa and eye protrusion. Imaging revealed a large osseous mass originating from the right turbinates, causing exophthalmos without tissue invasion. A partial resection via the Caldwell-Luc approach was performed, but hemodynamic instability halted the procedure, leaving a residual mass.

Venom composition, toxicity and cross-neutralization by PoliVal-ICP antivenom, of Mesoamerican jumping pitvipers genus Metlapilcoatlus (Viperidae: Crotalinae).

Background: The genus Metlapilcoatlus was recently erected to include six species of stout venomous snakes, known as the jumping pitvipers, which inhabit mountainous areas of Mesoamerica. This group maintains affinity with Atropoides picadoi, another jumping pitviper with restricted distribution in Costa Rica and Panama. Although the venom of A.
