Behcet's disease in a tertiary eye hospital in Pakistan.

Behçet's disease is a kind of variable vessel vasculitis (VVV) and inflammatory systematic disease affecting various organs of the body. The cause of the disease is idiopathic but is most commonly genetic in origin. A positive skin prick test (dermatographia), genital sores, eye irritation, skin sores, and at least three episodes of mouth sores in a year confirm the diagnosis.

Therapeutic Potential of Crocin and Nobiletin in a Mouse Model of Dry Eye Disease: Modulation of the Inflammatory Response and Protection of the Ocular Surface.

Treatment strategies include the use of antimicrobial medications and providing supportive care. Spiramycin is commonly used to treat toxoplasmosis in pregnant women and to hinder the disease's transmission.

Role of Adenosine A1 Receptor in Sleep Deprivation-Induced Neuroinflammation: Insights on Rapid Eye Movement Sleep and Fear Extinction Memory Recall in Rats.

Introduction: Sleep deprivation (SD), stemming from a myriad of aetiologies, is a prevalent health condition frequently overlooked. It typically impairs memory consolidation and synaptic plasticity, potentially through neuroinflammatory mechanisms and adenosinergic signalling. It is still unclear whether the adenosine A1 receptor (A1R) modulates SD-induced neurological deficits in the hippocampus.

Intraocular Inflammation Following Intravitreal Faricimab Injection in Neovascular Age-Related Macular Degeneration.

We herein report intraocular inflammation (IOI) following intravitreal (IVT) faricimab injection in three patients. A 73-year-old male, a 68-year-old female, and an 82-year-old female, all diagnosed with neovascular age-related macular degeneration (AMD), had received multiple anti-vascular endothelial growth factor (anti-VEGF) injections for the same. They were injected with IVT faricimab due to non-response to other agents.

Eye metrics are a marker of visual conscious awareness and neural processing in cerebral blindness.

Damage to the primary visual pathway can cause vision loss. Some cerebrally blind people retain degraded vision or sensations and can perform visually guided behaviors. These cases motivate investigation and debate on blind field conscious awareness and linked residual neural processing.

Tissue-specific modulation of NADH consumption as an anti-aging intervention in Drosophila.

Aging is characterized by extensive metabolic dysregulation. Redox coenzyme nicotinamide adenine dinucleotide (NAD) can exist in oxidized (NAD) or reduced (NADH) states, which together form a key NADH/NAD redox pair. Total levels of NAD decline with age in a tissue-specific manner, thereby playing a significant role in the aging process.

LDHAα, a lactate dehydrogenase A isoform, promotes glycolysis and tumor progression.

Lactate dehydrogenase A (LDHA) is upregulated in multiple cancer types and contributes to the Warburg effect. Several studies have found that many tumor-related genes have subtypes and play important roles in promoting cancer development. Here, we identified a novel LDHA transcript, which produced a new protein 3 kDa larger than LDHA, which we named LDHAα.

Effects of sunflower cake in lamb diets on meat quality and its fatty acid profile.

Virtual Human Retina: Simulating Neural Signalling, Degeneration, and Responses to Electrical Stimulation.

Introduction: Current brain-based visual prostheses pose significant challenges impeding adoption such as the necessarily complex surgeries and occurrence of more substantial side effects due to the sensitivity of the brain. This has led to much effort toward vision restoration being focused on the more approachable part of the brain - the retina. Here we introduce a novel, parameterized simulation platform that enables study of human retinal degeneration and optimization of stimulation strategies.

Optimized PLGA Encapsulated SA-2 Nanosuspension Exhibits Sustained Intraocular Pressure Reduction in the Mouse Microbead Occlusion Model of Ocular Hypertension.

Elevated intraocular pressure (IOP) is implicated in the structural and functional damage to the retinal ganglion cells (RGCs) in primary open-angle glaucoma (POAG). Topical IOP lowering agents provide short-term relief, necessitating frequent dosing. Moreover, non-adherence to frequent eyedrops administration contributes significantly to visual field loss and worsens the disease outcome.

A multicenter Phase II randomized, placebo-controlled single-blind trial with the SV2A ligand seletracetam in photosensitive epilepsy patients.

The objective of this study was to evaluate the effect of seletracetam (SEL), a potent modulator of synaptic vesicle glycoprotein 2A (SV2A), in patients with photoparoxysmal EEG response (PPR) to intermittent photic stimulation (IPS) as proof-of-principle of efficacy in patients with epilepsy. In this multicenter, single-blind Phase II study, adults with photosensitive epilepsy, with/without concomitant antiseizure medication therapy, underwent IPS under 3 eye conditions (at eye closure, eyes closed and eyes open) after a single oral dose of placebo (day - 1) or SEL (day 1; 0.5, 1, 2, 4, 10, or 20 mg).

Biology-inspired dynamic microphysiological system approaches to revolutionize basic research, healthcare and animal welfare.

The regular workshops held by the Center for Alternatives to Animal Testing (CAAT) on biology-inspired microphysiological systems (MPS) taking place every four years, have become a reliable measure to assess fundamental scientific, industrial and regulatory trends for translational science in the MPS-field from a bird's eye view. The 2023 workshop participants at that time concluded that the technology as used within academia has matured significantly, underlined by the broad use of MPS and the steadily increasing number of high quality research publications - yet, broad industry adoption of MPS has been slow, despite strong interest. Academic research using MPS primarily aims to accurately recapitulate human biology in MPS-based organ models in areas where traditional models have been lacking key elements of human physiology, thereby enabling breakthrough discoveries for life sciences.
