This paper presents a novel search metaheuristic inspired from the physical interpretation of the optic flow of information in honeybees about the spatial surroundings that help them orient themselves and navigate through search space while foraging. The interpreted behavior combined with the minimal foraging is simulated by the artificial bee colony algorithm to develop a robust search technique that exhibits elevated performance in multidimensional objective space. Through detailed experimental study and rigorous analysis, we highlight the statistical superiority enjoyed by our algorithm over a wide variety of functions as compared to some highly competitive state-of-the-art methods.

A lateral flow assay (LFA) was developed for the simultaneous or separate detection of mercury ion and silver ion based on isothermal nucleic acid amplification. T-Hg-T and C-Ag-C were utilized in the isothermal nucleic acid amplification strategy to form specific complementary base pairs. Under the action of KF polymerase and endonuclease Nt.

We describe a patient with severe Arnold Chiari Malformation and syringomyelia who underwent gynecological laparoscopy in an emergency context; no brain imaging was available. We here report the successful use of optic nerve sheath diameter (ONSD) and middle cerebral artery (MCA) velocity measurements as surrogate monitoring for cerebral blood flow and intracranial pressure, respectively. MCA velocity was low when assessed after peritoneal insufflation and ONSD increased to 6.

Aim: To compare the macular and optic nerve perfusion and vascular architecture using optical coherence tomography angiography (OCTA) in normal eyes of Egyptian (Caucasians) and South Asian (Asians) volunteers.
Methods: Cross-sectional analytical OCTA study performed on 90 eyes of South Asian (=45) and Egyptians (=45) were analyzed. All participants underwent best-corrected visual acuity test, slit lamp, and fundus examination.

Glaucoma is a chronic optic neuropathy that causes characteristic visual field defects and is considered one of the leading causes of irreversible vision loss worldwide. Lowering intraocular pressure is the only proven treatment for glaucoma. Medical therapy is usually the first-line treatment for open-angle glaucoma and ocular hypertension.

Although these hormones cross the blood-retinal barrier and bind to intraocular receptors, their effects remain unclear. We present the first review to date on associations between posterior pole structures-specifically the macula, choroid, and optic disc-and both the menstrual cycle and post-menopausal period, utilising multimodal imaging techniques in healthy adult non-pregnant women.
