Special Issue Information

Dear Colleagues,

Optical measuring methods are constantly attracting more interest in the life sciences, and recent advances have opened up new possibilities for measuring, sensing, and imaging with light. These have been successfully applied in many medical imaging laboratories, helping in the performance of various biomedical tests and diagnoses. This Special Issue of Applied Sciences titled “Optical Measuring Methods for Application in Biology and Medicine” aims to attract high-quality research papers related to these areas.

Original papers presenting recent research results and reviews summarizing the state-of-the-art are welcome for publication. Papers covering topics on fiber-optic sensors, spectroscopy, OCT, interferometry, microscopy, imaging, and other optical methods are just some of the topics of interest.

We encourage you to take part in this Special Issue and look forward to your valuable contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Previous studies have indicated that changes in oxygenated hemoglobin concentration (O2Hb) in the prefrontal cortex (PFC) are associated with changes in cognitive function. Therefore, the present study aimed to explore the effect of differences in O2Hb levels in the left and right PFC (L-PFC and R-PFC, respectively) on cognitive function after exercise. This study included 12 healthy male college students. The exercise regimen consisted of 4 min of warm-up and rest each, followed by 20 min of moderate-intensity exercise and 20 min of post-exercise rest. Participants underwent the 2-back cognitive test thrice (pre-exercise, post-exercise, and after the 20 min post-exercise rest period), and their reaction times were recorded. O2Hb levels in the PFC were monitored using functional near-infrared spectroscopy. We analyzed the correlations between changes in post-exercise reaction times and differences in peak O2Hb levels (L-PFC minus R-PFC), area under the curve for O2Hb changes, and increases in the O2Hb slope during exercise. Peak O2Hb, area under the curve (AUC) for O2Hb change, and increase in the slope of O2Hb were significantly correlated with changes in reaction time. These findings provide insight into the mechanism by which O2Hb differences between the L-PFC and R-PFC affect cognitive function. Full article

This report includes a case of a 65-year-old woman presenting with a spontaneous dural carotid-cavernous fistula. Biomicroscopic examination of the anterior segment showed significant conjunctival chemosis, dilatation of the episcleral vessels, narrow anterior chamber, and a proptosis of the right eye, whereas the fellow eye was unremarkable. Retinal examination revealed an impaired arteriovenous ratio (A/V) from 1–4 to 1–2 and two extensive cotton exudates. An ultrasound scan (US) demonstrated congestion of the upper ophthalmic vein. Selective brain angiography through right femoral catheterization revealed a dural fistula of the wall of the cavernous right sinus. The patient underwent surgery on the superior ophthalmic vein and insertion of a micro-catheter in the cavernous sinus under CT guidance. Furthermore, a trans-femoral catheter was placed in the carotid artery on the same side as the fistula to allow arteriographic controls after micro coil positioning and embolization. Angiographic follow-up immediately after positioning the coils showed the occluded fistula and a regular flow circulation between the internal and the external carotid arteries. After treatment, the patient presented a complete resolution of symptoms. Conservative management is effective and safe in treating patients with carotid-cavernous fistula and mild clinical features because of a good chance of spontaneous or secondary thrombosis after arteriographic occlusion.
