Exploring the Linkage Between Ruminal Microbial Communities on Postweaning and Finishing Diets and Their Relation to Residual Feed Intake in Beef Cattle.

Feed efficiency significantly impacts the economics of beef production and is influenced by biological and environmental factors. The rumen microbiota plays a crucial role in efficiency, with studies increasingly focused on its relationship with different rearing systems. This study analyzed 324 rumen samples from bulls and steers categorized as high and low efficiency based on residual feed intake.

Enrolment characteristics in age-related macular degeneration clinical trials: a cross-sectional study.

Background/objectives: To investigate demographic enrolment characteristics in age-related macular degeneration (AMD) trials.

Subjects/methods: Clinicaltrials.gov was searched with "age-related macular degeneration" to identify RCTs with double, triple, or quadruple masking.

Face Masking and Risk of Post-Intravitreal Injection Endophthalmitis: A Network Meta-Analysis of 2.6 Million Injections.

Topic: To compare face masking protocols for post-intravitreal injection endophthalmitis (PIE) prophylaxis.

Clinical Relevance: Though mask mandates are lifted, ophthalmologists may question whether continued investment into face masks will influence their PIE rate.

Methods/literature Reviewed: We included comparative studies of PIE incidence by masking policy (i.

Structural effects of intraretinal cysts on outer retinal layers in eyes with diabetic macular edema.

Background: Diabetic macular edema (DME) is the main cause of visual loss in individuals with diabetic retinopathy (DR). This study aims to investigate the effects of central macular intraretinal cysts on the underlying outer retinal layer (ORL) in patients with diabetic macular edema (DME).

Methods: In this retrospective and cross-sectional study, diabetic patients with or without DR were categorized into three groups: without DME (group 1), with DME but without any cyst featuring a plateau in the lower region (group 2), and patients with cyst featuring an inferior cyst plateau (group 3), defined as a flat conformation at its posterior aspect.

Single-Shot Ultra-Widefield Polarization-Diversity Optical Coherence Tomography for Assessing Retinal and Choroidal Pathologies.

: Optical coherence tomography (OCT) is a leading ocular imaging modality, known for delivering high-resolution volumetric morphological images. However, conventional OCT systems are limited by their narrow field-of-view (FOV) and their reliance on scattering contrast, lacking molecular specificity. : To address these limitations, we developed a custom-built 105 ultra-widefield polarization-diversity OCT (UWF PD-OCT) system for assessing various retinal and choroidal conditions, which is particularly advantageous for visualizing peripheral retinal abnormalities.
