Purpose: To characterize the appearance of the far peripheral retina of normal eyes using ultra-widefield fluorescein angiography (UWFA).
Design: Cross-sectional study.
Methods: This study enrolled 101 eyes with best-corrected visual acuity ≥20/20, with refractive error <3.00 diopters, and without visible retinal pathologic changes under a slit lamp-based condensing lens. The far peripheral retina was detected by UWFA. Ciliary body thickness (CBT) at 3 mm (CBT1) and 2 mm (CBT2) posterior to the scleral spur was measured by ultrasound biomicroscopy.
Results: In the far peripheral retina, granular background fluorescence (GB) appeared in all eyes (100%), a mottled fluorescent band (MB) appeared in 44 eyes (43.6%), and retinal vascular leakage (VL) appeared in 20 eyes (19.8%). According to peripheral angiographic findings, the eyes were allocated into 3 groups: Group 1 (MB- and VL-), Group 2 (MB+ and VL-), and Group 3 (MB-/+ and VL+). Ultrasound biomicroscopy showed ciliary body edema and exudates in Group 3. The mean CBT1 (mm) and CBT2 (mm) of Group 3 were greater than those of Group 1 and Group 2 (0.315 ± 0.037 vs 0.240 ± 0.019 vs 0.251 ± 0.030; 0.571 ± 0.084 vs 0.375 ± 0.051 vs 0.410 ± 0.050, P < .001 for both CBT1 and CBT2). The mean CBT1 and CBT2 showed no difference between Group 1 and Group 2 (P = .575 for CBT1; P = .150 for CBT2).
Conclusions: Normal peripheral retinas generally show granular background fluorescence, with or without a mottled fluorescent band.

The ongoing COVID-19 pandemic has triggered extensive research, mainly focused on identifying effective therapeutic agents, specifically those targeting highly pathogenic SARS-CoV-2 variants. This study aimed to investigate the antiviral efficacy and anti-inflammatory activity of herbal extracts derived from and , using a Golden Syrian hamster model infected with Delta, a representative variant associated with severe COVID-19. Hamsters were intranasally inoculated with the SARS-CoV-2 Delta variant and orally administered either vehicle control, , or extract at a dosage of 1000 mg/kg/day.

The investigation of microRNAs (miRNAs) for the purpose of identifying biomarkers and new treatments for breast cancer has been gaining traction from scientists in recent years. Of all the miRNAs, miR-155 has been reportedly involved in breast cancer development as it regulates various cellular processes such as glucose uptake, proliferation, metastasis, and migration. Various efforts have been done towards researching miR-155 as a biomarker in breast cancer; however, the results were varied.

Background: Guillain-Barré syndrome (GBS) is a rapid-onset disease caused by the immune system damaging the peripheral nervous system. Since most standardized treatments for GBS focus on acute phase treatment, there are limitations to the rehabilitation and management of general conditions. In East Asian countries, herbal medicine has been used to treat GBS and aid rehabilitation.

People with Down Syndrome (DS) are at high risk of developing Alzheimer's disease dementia (AD) and cerebral amyloid angiopathy, which is a critical factor contributing to dementia in sporadic AD. Predicting and monitoring the decline and onset of dementia is a diagnostic challenge and of essence in daily care and support for people with DS. In this literature scoping review, we first summarize the different blood-based biomarkers for AD in DS.

Background: Coronavirus disease 2019 (COVID-19), resulting from the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), affects various bodily systems, including the heart, central nervous system, muscles, and bones, all of which harbor angiotensin-converting enzyme 2 (ACE-2) receptors similar to those in the respiratory system. However, research on the inflammatory response and its impact on systems such as the musculoskeletal one is relatively scarce. Our study aimed to investigate bone and muscle metrics as well as handgrip strength in individuals who recuperated from COVID-19 infection.
