A High-Throughput Microphysiological Liver Chip System to Model Drug-Induced Liver Injury Using Human Liver Organoids.

Background And Aims: Drug-induced liver injury (DILI) is a major failure mode in pharmaceutical development. This study aims to address the limitations of existing preclinical models by assessing a high-throughput, microfluidic liver-on-a-chip system, termed "Curio Barrier Liver Chips," and its capacity to recapitulate the effects of chronic hepatotoxic drug treatment through metabolic and phenotypic characterization.

Methods: Curio Barrier liver chips (Curiochips), fabricated in an 8 × 2 well configuration, were utilized to establish three dimensional liver organoid cultures.

Central Retinal Artery Occlusion Following Intralesional Triamcinolone Injection for IgG4-related Orbital Disease.

The risk of blindness associated with periocular and facial injections is well documented. Previous cases describing vision loss following a recent periocular or facial injection have emphasized the importance of facial "danger zones." To date, the literature suggests that nearly half of all cases of central retinal artery occlusion in the setting of a recent periocular or facial injection involve an injection in or around the nose.

Müller Muscle Conjunctival Resection: A Prospective Multicenter Comparison of Eyelid Height at the Immediate, 1-Week, and 3-Month Postoperative Time Points.

Purpose: The primary objective was to document change in postoperative marginal reflex distance-1 (MRD1) after Müller muscle conjunctival resection surgery. The secondary objective was to identify predictors of change in postoperative MRD1.

Methods: A multicenter prospective cohort study was performed on patients consecutively recruited for Müller muscle conjunctival resection.

Discovering type I cis-AT polyketides through computational mass spectrometry and genome mining with Seq2PKS.

Type 1 polyketides are a major class of natural products used as antiviral, antibiotic, antifungal, antiparasitic, immunosuppressive, and antitumor drugs. Analysis of public microbial genomes leads to the discovery of over sixty thousand type 1 polyketide gene clusters. However, the molecular products of only about a hundred of these clusters are characterized, leaving most metabolites unknown.

Transcutaneous Retrobulbar Amphotericin B Injection for Invasive Fungal Sinusitis with Orbital Involvement: A Systematic Review.

Background: Orbital involvement of invasive fungal sinusitis (IFS) is an ominous prognostic marker that should prompt rapid intervention. Transcutaneous retrobulbar administration of amphotericin B (TRAMB) is an off-label adjunctive treatment that can increase drug penetrance into diseased orbital tissue. To date, there is a lack of consensus regarding the use of TRAMB for treatment of IFS with orbital involvement.

Invasive Fungal Sinusitis in an Immunocompetent Patient After Sinus Surgery for Chronic Rhinosinusitis with Nasal Polyps and a Mycetoma.

Acute invasive fungal sinusitis (AIFS) classically presents as an aggressive fungal infection that can spread beyond its origin in the sinuses in immunocompromised patients. Although there have been reports of AIFS in immunocompetent, non-diabetic patients, it is extremely rare and the true mechanism behind it is unknown. A thirty-eight year old immunocompetent, non-diabetic woman underwent bilateral ESS for chronic rhinosinusitis with nasal polyps at a tertiary care center and post-operatively developed AIFS.

Laminin 511-E8, an autoantigen in IgG4-related cholangitis, contributes to cholangiocyte protection.

Background & Aims: IgG4-related cholangitis (IRC) is the hepatobiliary manifestation of IgG4-related disease. Anti-laminin 511-E8 autoantibodies have been identified in its pancreatic manifestation. Laminin 511-E8 promotes endothelial barrier function, lymphocyte recruitment, and cholangiocyte differentiation.

Plant peptides - redefining an area of ribosomally synthesized and post-translationally modified peptides.

Covering 1965 to February 2024Plants are prolific peptide chemists and are known to make thousands of different peptidic molecules. These peptides vary dramatically in their size, chemistry, and bioactivity. Despite their differences, all plant peptides to date are biosynthesized as ribosomally synthesized and post-translationally modified peptides (RiPPs).

Evaluating for unrecognized deficits in perimetry associated with functional upper eyelid malposition.

Objective: To investigate whether functional upper eyelid malposition is associated with unrecognized deficits in automated perimetry among glaucoma patients by examining patients undergoing eyelid surgery who had not been identified as requiring eyelid taping during glaucoma field testing.

Methods: In this retrospective pre-post study, an automated database search followed by manual chart review was used to identify eligible patients from January 2012 to March 2020. Included patients had reliable visual field testing within two years before and after functional upper blepharoplasty or ptosis repair and no comorbid ocular diagnoses.

An intramolecular macrocyclase in plant ribosomal peptide biosynthesis.

The biosynthetic dogma of ribosomally synthesized and posttranslationally modified peptides (RiPP) involves enzymatic intermolecular modification of core peptide motifs in precursor peptides. The plant-specific BURP-domain protein family, named after their four founding members, includes autocatalytic peptide cyclases involved in the biosynthesis of side-chain-macrocyclic plant RiPPs. Here we show that AhyBURP, a representative of the founding Unknown Seed Protein-type BURP-domain subfamily, catalyzes intramolecular macrocyclizations of its core peptide during the sequential biosynthesis of monocyclic lyciumin I via glycine-tryptophan crosslinking and bicyclic legumenin via glutamine-tyrosine crosslinking.

Galectin-3 and prohibitin 1 are autoantigens in IgG4-related cholangitis without clear-cut protective effects against toxic bile acids.

Background And Aims: IgG4-related cholangitis (IRC) is the hepatobiliary manifestation of IgG4-related disease, a systemic B cell-driven fibro-inflammatory disorder. Four autoantigens have recently been described in IgG4-RD: annexin A11, galectin-3, laminin 511-E8, and prohibitin 1. We have previously reported a protective role of annexin A11 and laminin 511-E8 in human cholangiocytes against toxic bile acids.

Outcomes for expanded polytetrafluoroethylene strip in frontalis suspension surgery.

Purpose: This study evaluates surgical outcomes and complication rates of frontalis suspension with expanded polytetrafluoroethylene (ePTFE).

Methods: This retrospective cohort study reviewed all patients undergoing frontalis suspension surgery using ePTFE as the sling material from January 1 2012 to March 3 2020 by a single surgeon at a single academic center. Two different surgical techniques were evaluated in the placement of the sling material.

Human aggression in everyday life: An empirical test of the general aggression model.

With the general aggression model (GAM), Anderson and Bushman (2002) provided an integrative framework to explain the complex nature of aggression. Based on the GAM, we examined whether personological and situational factors (interactively) have an impact on the person's internal state (consisting of aggressive cognition, affect, and physiological arousal), which in turn is assumed to lead to aggressive behaviour. In a large-scale experience sampling study, 403 participants answered 7558 questionnaires over a period of 2 weeks.

Myomatrix arrays for high-definition muscle recording.

Neurons coordinate their activity to produce an astonishing variety of motor behaviors. Our present understanding of motor control has grown rapidly thanks to new methods for recording and analyzing populations of many individual neurons over time. In contrast, current methods for recording the nervous system's actual motor output - the activation of muscle fibers by motor neurons - typically cannot detect the individual electrical events produced by muscle fibers during natural behaviors and scale poorly across species and muscle groups.

Cutaneous Mucormycosis of the Eyelid Treated With Subcutaneous Liposomal Amphotericin B Injections.

Cutaneous mucormycosis is a rare, opportunistic fungal infection that typically affects immunocompromised hosts. Current treatment consists of systemic antifungal therapy, surgical debridement, and when applicable, restoration of immune function. Despite intervention, the morbidity and mortality of invasive fungal disease remains high.

12-Year clinical and radiological results of a double-blind randomized controlled trial comparing posterior cruciate-retaining versus posterior-stabilized total knee arthroplasty.
