    1. The relation between red blood cell distribution width and coronary atherosclerotic plaque vulnerability detected by intracoronary optical coherence tomography

      The relation between red blood cell distribution width and coronary atherosclerotic plaque vulnerability detected by intracoronary optical coherence tomography

      Background: A higher red blood cell distribution width (RDW) predicts major adverse cardiac events in patients with coronary artery disease (CAD). However, there are only few studies regarding the relationship between RDW and vulnerable plaques. Thus, the purpose of present study is to retrospectively explore the predictive value of the association between RDW and plaque vulnerability assessed by optical coherence tomography (OCT) in patients with cardiovascular (CV) diseases. Methods: This study included 35 patients with stable angina pectoris (SAP) and 70 patients with acute coronary syndrome (ACS). We documented clinical features as well as peripheral RDW. Plaque vulnerability was determined ...

    2. A Review of Spectroscopic and Non-Spectroscopic Techniques for Diagnosing Breast Cancer

      A Review of Spectroscopic and Non-Spectroscopic Techniques for Diagnosing Breast Cancer

      Malignancy is one of the consequent driving explanations behind death worldwide, and it is assessed at 9.6 million in 2018. Around 1 out of 6 deaths are the direct result of the malignancy. Clinicians state, that age and breast density are two natural elements resulting in the danger of cancer. The mortality rate brought about by malignant growth in low and focus pay countries is, for the most part, around 70%. Imaging techniques play a vital role in detection, staging, and help in guiding treatment decisions. This review paper presents a comprehensive survey involving a literature study about the ...

    3. Intraoperative optical coherence tomography guided 25G micro-amount trajectory vitrectomy for the treatment of penetrating ocular injury caused by a foreign body in the right eye: A case study

      Intraoperative optical coherence tomography guided 25G micro-amount trajectory vitrectomy for the treatment of penetrating ocular injury caused by a foreign body in the right eye: A case study

      Background Optical coherence tomography (OCT) is a real-time three-dimensional tomography optical imaging technology that uses near-infrared waves to take cross-section pictures of the retina and other tissues. A few studies reported the use of intraoperative OCT navigation for the removal of foreign bodies from the eyeball during surgery. The objective is to present a single case with a small foreign body (not embedded in the retina) treated with intraoperative OCT guided 25G micro-amount trajectory vitrectomy. Case Presentation: A 25-year-old man who suffered from right eye pain, and his examination suggested the following: The visual acuity was 20/250, the intraocular ...

    4. Choroidal changes in carotid stenosis patients after stenting detected by swept-source optical coherence tomography angiography

      Choroidal changes in carotid stenosis patients after stenting detected by swept-source optical coherence tomography angiography

      Background: Carotid artery stenosis (CAS) patients show reduced blood flow in the ophthalmic artery. This study aimed to assess the changes in the choriocapillaris and choroidal thickness in patients with unilateral carotid artery stenosis after carotid stenting using swept-source optical coherence tomography (SS-OCT)/swept-source optical coherence tomography angiography (SS-OCTA). Methods: Fifty-three mild to moderate CAS patients and 40 controls were enrolled in this study. All participants underwent digital subtraction angiography (DSA) and SS-OCT/SS-OCTAA imaging before and 4 days after carotid artery stenting. SS-OCTA was used to image and measure the perfusion of the choriocapillaris (mm2) while SS-OCT was used ...

    5. Application of Artificial Intelligence in Targeting Retinal Diseases

      Application of Artificial Intelligence in Targeting Retinal Diseases

      Retinal diseases affect an increasing number of patients worldwide because of the aging population. Request for diagnostic imaging in ophthalmology is ramping up, while the number of specialists keeps shrinking. Cutting-edge technology embedding artificial intelligence (AI) algorithms is thus advocated to help ophthalmologists perform their clinical tasks as well as a source for novel biomarkers. In particular, optical coherence tomography (OCT) evaluation of the retina can be augmented by algorithms based on machine learning and deep learning to early detect, qualitatively localize and quantitatively measure epi/intra/subretinal abnormalities or pathological features of macular or neural diseases. In this paper ...

    6. The Gold Nanorod-Biology Interface: From Proteins to Cells to Tissue

      The Gold Nanorod-Biology Interface: From Proteins to Cells to Tissue

      Gold nanorods absorb and scatter light strongly in the near-infrared portion of the electromagnetic spectrum, making them ideal tissue contrast agents for imaging techniques such as optical coherence tomography (OCT). Strong interactions occur at the nano-bio interface, such as proteins binding to gold nanorods forming a ‘corona.’ To fulfill the promise of nanorods for applications such as contrast agents, we must better understand the intrinsic interactions of these nanomaterials with biological systems at the molecular, cellular and tissue level. In this paper, we briefly review the nanorod-protein interface. We then present some new fast relaxation imaging (FReI) measurements of how ...
