Purpose: To describe rapid loss of cone vision in an adult due to putative auto-immune rejection.
Methods: Clinical and electrophysiological examination, including full-field and multi-focal electroretinograms (ERGs), were used to assess retinal function. Serum was analyzed for antibodies to retinal antigens.
Results: The patient lost cone vision in the course of several months while rod vision remained unaffected. Initially short wavelength (S) cone function appeared more resistant to the degeneration. Cancer associated retinal antibodies were present in the sera of the patient but no cancer has been found.
Conclusion: Rapid loss of cone function can occur in an adult without a concomitant neoplasm although serum antibodies to retinal antigens suggest an autoimmune cause.

Black soldier fly larvae (BSFL) have several advantages, such as rapid growth and sustainable production. The electrospinning encapsulation shows promise for encapsulating oils, as it does not use high temperatures, preventing degradation. This study analyzed the incorporation of oil (15, 30, and 45 % w/w) from BSFL into fibers by electrospinning using zein (20 and 25 % w/v).

Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and progressive bulbar palsy, involve loss of muscle control resulting from death of motor neurons. Although the exact pathogenesis of these syndromes remains elusive, many are caused by genetically inherited mutations. Thus, it is valuable to identify additional genes that can impact motor neuron survival and function.

Uncontrollable haemorrhage and associated microbial contamination in the battlefield and civilian injuries pose a tremendous threat to healthcare professionals. Such traumatic wounds often necessitate an effective point-of-care solution to prevent the consequent morbidity owing to blood loss or haemorrhage. However, developing superior hemostatic materials with anti-infective properties remains a challenge.

Vasovagal syncope (VVS) in donors is a transient loss of consciousness due to short-term global cerebral hypoperfusion, which has a rapid onset and has complete spontaneous recovery. VVS may be triggered by pain, fear, anxiety, or emotional upset and loss of blood perse. It is an exaggeration of an adaptive response meant to assist in reducing the amount of bleeding/loss of blood.

CNS lymphoma is a rare form of non-Hodgkin lymphoma that primarily affects the brain, spinal cord, leptomeninges, or eyes, leading to severe neurological or ophthalmological complications. This case report details a 44-year-old male with human immunodeficiency virus and diffuse large B-cell lymphoma who experienced permanent vision loss due to optic perineuritis, a rare presenting symptom indicative of underlying CNS involvement. Despite previous remission, imaging revealed focal enhancements suggesting CNS lymphoma, highlighting diagnostic and management challenges in relapsed lymphoma, especially in immunocompromised patients.
