Background: Diagnostic orbito-ocular ultrasonography is a safe, affordable, and cost-effective procedure that is especially suited for resource-poor developing countries. Periodic evaluation of its utility and effectiveness is important in the light of phenomenal advances in medical imaging.
Objectives: To assess the utility and effectiveness of B-scan orbito-ocular ultrasonography in a Nigerian ophthalmic patient population.
Methods: The Hansa Clinic's database was retrospectively reviewed, between January 2006 and December 2010, to obtain patients' relevant demographic and clinical data. Results . The subjects comprised 119 males and 81 females. The leading sonographic diagnoses were ocular (90.4%): retinal detachment-23.3%, cataract-14.0%, and vitreous haemorrhage-10.5%; orbital (8.3%): 'mass lesion'-4.8% and myopathies-0.8%. The agreement between clinical and sonographic diagnoses was complete in 35.5% eyes.
Conclusion: At Hansa Clinics, intraocular lesions are the main findings of diagnostic orbito-ocular sonography. There is poor agreement between clinical and sonographic diagnoses. Improved correlation of patients' clinic-pathologic data is suggested.

Electronic address:
In clinical optical molecular imaging, the need for real-time high frame rates and low excitation doses to ensure patient safety inherently increases susceptibility to detection noise. Faced with the challenge of image degradation caused by severe noise, image denoising is essential for mitigating the trade-off between acquisition cost and image quality. However, prevailing deep learning methods exhibit uncontrollable and suboptimal performance with limited interpretability, primarily due to neglecting underlying physical model and frequency information.

Background: Shared decision-making between clinicians and service users is crucial in mental health care. One significant barrier to achieving this goal is the lack of user-centered services. Integrating digital tools into mental health services holds promise for addressing some of these challenges.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN.
Background And Objectives: Chronic kidney disease (CKD) is known to be associated with increased plasma phosphorylated tau217 (p-tau217) concentrations, potentially confounding the utility of plasma p-tau217 measurements as a marker of amyloid pathology in individuals with suspected Alzheimer disease (AD). In this study, we quantitatively investigate the relationship of plasma p-tau217 concentrations vs estimated glomerular filtration rate (eGFR) in individuals with CKD with and without amyloid pathology.
Methods: This was a retrospective examination of data from 2 observational cohorts from either the Mayo Clinic Study of Aging or the Alzheimer's Disease Research Center cohorts.
BuDDI: Bulk Deconvolution with Domain Invariance to predict cell-type-specific perturbations from bulk.

While single-cell experiments provide deep cellular resolution within a single sample, some single-cell experiments are inherently more challenging than bulk experiments due to dissociation difficulties, cost, or limited tissue availability. This creates a situation where we have deep cellular profiles of one sample or condition, and bulk profiles across multiple samples and conditions. To bridge this gap, we propose BuDDI (BUlk Deconvolution with Domain Invariance).
