A procedure for creating and imaging capillary bridges in slit-pore geometry is presented. The creation of capillary bridges relies on the formation of pillars to provide a directional physical and chemical heterogeneity to pin the fluid. Capillary bridges are formed and manipulated using microstages and visualized using a CCD camera.

Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA The simplest ophthalmoscopes consist of an aperture to look through, a diopter indicator, and a disc for selecting lenses. The ophthalmoscope is primarily used to examine the fundus, or the inner wall of the posterior eye, which consists of the choroid, retina, fovea, macula, optic disc, and retinal vessels (Figure 1). The spherical eyeball...

Diagnosis of Eimeria infection in chickens remains demanding. Parasite morphology- and host pathology-led approaches are commonly inconclusive, while molecular approaches based on PCR have proven demanding in cost and expertise. The aim of this protocol is to establish loop-mediated isothermal amplification (LAMP) as a straightforward molecular diagnostic for eimerian infection.

Source: Carmen Black, Matthew Goldenberg, and Jaideep Talwalkar; Yale School of Medicine The mental status exam is a clinical evaluation of emotional, perceptual, and cognitive functioning that spans both the fields of psychiatry and neurology. Developing skill in the psychiatric portions of the examination are important to describe salient aspects of the patient's mental state that may be observed during routine history and/or physical exam. Proficiency in the cognitive portions of this...

Source: Heather Collette and Jaideep Talwalkar; Yale School of Medicine The newborn exam is important in establishing a baby's baseline health status as they enter the world. Newborn providers have the unique opportunity to evaluate a patient for the very first time. They are also tasked with identifying congenital anomalies that require early intervention to promote a long and healthy life for the child. Many newborn anomalies, such as heart defects, are noted on prenatal ultrasound. However,...
FAQs
These adjustments change how the illuminated ocular tissue is presented to the examiner. A narrow or wider slit, different beam angle, and altered magnification allow the clinician to inspect structures under different viewing conditions rather than relying on one fixed image. This flexibility helps reveal subtle abnormalities and supports targeted assessment of specific eye regions.
The binocular microscope provides high magnification while allowing the examiner to view ocular structures through both optical channels. This makes small abnormalities easier to identify and supports detailed inspection of tissues that may not be adequately characterized at lower magnification. The resulting observations can contribute to clinical diagnosis, follow-up, and documentation.
A focused slit isolates a thin section of illuminated ocular tissue, helping the examiner examine localized regions rather than viewing the eye only as a broadly illuminated surface. This focused approach supports more precise inspection of structures such as the cornea, anterior chamber, iris, and lens, where subtle abnormalities may otherwise be difficult to distinguish.
Specialized lenses expand the examination beyond the structures directly assessed through the standard viewing setup. They can support evaluation of the retina and optic nerve, extending the method’s usefulness to additional parts of the eye. This broader reach allows clinicians to incorporate posterior ocular structures into a more comprehensive ophthalmic assessment.
The examiner views the eye through the binocular microscope while directing a focused slit of light onto ocular tissue. Beam width, illumination angle, and magnification are adjusted as different regions are assessed. The examination can proceed across the eyelids, conjunctiva, cornea, anterior chamber, iris, and lens, with specialized lenses used when the retina or optic nerve must be examined.
Clinicians use the findings to support diagnosis, monitor changes, and document ocular conditions. The examination is relevant when evaluating problems such as corneal injury, cataracts, glaucoma, or inflammation. Because it provides detailed observations across several eye structures, it can also help establish a record for comparing findings during ongoing care.
It can reveal detailed structural abnormalities across multiple ocular regions, including the external eye, cornea, anterior chamber, iris, and lens. With specialized lenses, assessment may also include the retina and optic nerve. These observations provide information that clinicians can use to identify disease-related changes, follow their progression, and document examination results.
