To evaluate the course of parasitemia and the associated lesions, mice were inoculated intraperitoneally with either WA1-infected, B. microti-infected, or uninfected hamster red blood cells. WA1-infected mice developed dyspnea and moderate parasitemias, after which death occurred. Babesia microti-infected mice experienced low parasitemias with no apparent morbidity or mortality. WA1-infected mice were thrombocytopenic but not anemic. Hemograms for B. microti-infected mice were similar to controls. Postmortem examination of WA1-infected mice revealed ...
TY - JOUR. T1 - Correlation of full-thickness corneal wound length with endothelial cell loss. AU - Kletzky, D. L.. AU - Parver, L. M.. AU - Mathers, W. D.. PY - 1992/1/1. Y1 - 1992/1/1. N2 - We studied 12 patients who had sustained penetrating corneal lacerations with corneal wound lengths ranging from 1 to 9 mm to determine whether wound size was directly proportional to endothelial cell loss 3 or more months after injury. Endothelial cell counts in the uninjured eye averaged 2973 ± 330 cells/mm2 (range, 2500 to 3700). In the injured eye, near the wound (, 2 mm from the wound), the cell counts averaged 1260 ± 590 cells/mm2 (range, 575 to 2500); away from the wound, where cells appeared healthiest, counts averaged 1619 ± 544 cells/mm2 (range, 850 to 2750). The average total cell loss near the wound was 1713 ± 622 cells/mm2 (range, 500 to 2575), vs 1354 ± 582 cells/mm2 (range, 250 to 2150) away from the wound, compared with the uninjured eye. Cell loss near the wound was not significantly ...
Purpose: To evaluate corneal endothelial cell loss after phaco with ExPress implant compared to phaco trabeculectomy. Methods: Forty eyes of forty patients affected by cataract and open angle glaucoma were randomized to Micro incision cataract surgery (MICS) phaco with Express P50 implant under scleral flap (group 1) or MICS safe-phacotrabeculectomy (group 2) after informed consent. All patients were operated by two-site surgery. There were no statistically significant differences in age, sex, anterior chamber depth and axial length. Non contact corneal specular microscopy (Tomey 3000 tm) was performed in all eyes before and 1st, 3rd , 6th months after surgery. Endothelial cell density (CCD), coefficient of variation in cell size (CV) and percentage of hexagram cells (HEX) between the two groups were considered before and after surgery. Mean endothelial cell count was measured in the central corneal area and in the superior area close to Express implant and close to trabeculectomy site. One-way ...

Endothelial cell changes occurring upon chemotherapy exposure in mice can create an environment favorable for metastasis formation through expression of VEGFR-1.
Fuchs endothelial dystrophy is a non-inflammatory, sporadic or autosomal dominant, dystrophy involving the endothelial layer of the cornea. With Fuchs dystrophy the cornea begins to swell causing glare, halo, and reduced visual acuity. The damage to the cornea in Fuchs endothelial dystrophy can be so severe as to cause corneal blindness.
Cataract surgical techniques have significantly changed in recent years with the widespread adoption of smaller and smaller clear corneal incisions for phacoemulsification. Microincision surgery has many advantages, including reduced surgically induced astigmatism, faster visual recovery, and reduced intra and postoperative inflammation. In the recent times, microcoaxial phacoemulsification has gained popularity. The main advantage of this newer technique is that it uses the same methods as the conventional method but with smaller incisions. Curently, microcoaxial phacoemulsification is being performed through 1.8 as well as 2.2 mm incisions. However, there is still a debate as to which is the best absolute incision size for microcoaxial cataract surgery.. The aim of this study is to evaluate incision stability following microcoaxial phacoemulsification performed through 1.8 and 2.2 mm systems, as well as compare intraoperative performance and postoperative outcomes following microcoaxial ...
Laser eye surgery to correct vision problems does not appear to be associated with lasting changes to cells lining the inside of the cornea at nine years after the procedure, according to a report in the November issue of Archives of Ophthalmology, one of the JAMA/Archives journals.. Two types of laser surgeryphotorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK)are often used to correct refractive errors such as nearsightedness, according to background information in the article. Little is known about how these procedures affect the cornea, the transparent membrane covering the eye, on the cellular level over the long term.. Sanjay V. Patel, M.D., and William M. Bourne, M.D., of Mayo Clinic, Rochester, Minn., studied 29 eyes of 16 patients who had undergone LASIK or PRK. Photographs of the cells lining the cornea (endothelial cells) were taken and analyzed before and nine years after surgery. The annual rate of corneal endothelial cell loss in the eyes of patients who ...
In a clinical prospective, randomised study, 28 cataract eyes with a median age of 74.96 years were enrolled and devided into 4 groups: group 1 = 0.9 mm incision, group 2 = 1.8 mm incision, group 3 = 2.2 mm incision using the newly developed microincision forceps. The data was compared to the control group 4 eyes with a 2.2 mm incision using standard utrata forceps. Incision size was measured using a caliper intraoperativly and capsulorhexis shape was evaluated by analyzing surgical videos ...
Fuchs endothelial dystrophy is a progressive, bilateral disease of the corneal endothelium, which eventually leads to corneal decompensation. In the early stage, some patients develop visually significant cataract. During cataract surgery ultrasound (US) power is used to emulsify the lens, which leads to endothelial cell loss and tissue damage. The reduction of US power has become the primary surgical goal in cataract surgery, which is especially important in patients with Fuchs endothelial dystrophy to limit endothelial cell loss.. In 2006, Alcon Surgical introduced a torsional mode in its phacoemulsification system (Infiniti Vision System). It includes a handpiece that produces rotary oscillations of the phacoemulsification tip and is suggested to reduce the amount of US power required to remove the cataractous nucleus, because it does not produce repulsion and breaks up the cataract by shearing and not by the conventional jackhammer effect. This reduction in US power, could lead to less ...
Methods 19 human corneoscleral rims were divided into six groups, mounted on an anterior chamber maintainer and cut with a femtosecond laser programmed to the following patterns: zigzag (A), mushroom (B) and top hat (C) in both full (1) and partial (2) thicknesses. The pressure required to produce leakage from the corneal incision was then measured. Eight additional corneas were cut with the zigzag pattern: four full and four partial thickness, prepared and transported per standard eye bank protocol, and analysed for endothelial cell loss with trypan blue staining and digital image analysis.. ...
Despite the fact that the GWAS publication noted that genetic variations in TCF4 polymorphisms contribute to the development of FED, this correlation also needs to be verified by a case control study. Therefore, we performed this meta-analysis to provide the highest level of evidence for the association between TCF4 polymorphisms and the risk of FED. With a total of 5370 participants, this meta-analysis focused on the association between TCF4 variants and the risk of FED, thirteen studies addressing one or more SNPs in TCF4 (rs613872, rs17595731, rs9954153, and rs2286812) were included. The pooled results showed that a significant association was detected between FED risk and the rs17595731, rs613872, rs9954153, and rs2286812 SNPs. This s consistent with the findings presented in the GWAS publication [8]. For rs613872, in order to achieve robust and reliable results for the meta-analysis of the association between rs613872 and FED risk, we performed a series of analyses. These sensitivity ...
A widely known D cartridge is mostly used to inject hydrophobic acrylic IOLs with a wound assisted technique through 2.2-2.4 mm incisions. The wound stretch through these incision sizes has been shown to be limited and is widely accepted. The main innovative features of the new cartridge system are 1) dedicated depth guard behind the cartridge tip, ensuring a fixed and controlled entry of the tip into the corneal incision. 2) a single hand push injection mechanism which allows an uninterrupted IOL delivery ...

At the 10-year time point after Descemet stripping endothelial keratoplasty, the endothelial cell density is comparable to that after penetrating keratoplasty at the same time.
Functional impairment of the human corneal endothelium can lead to corneal blindness. In order to meet the high demand for transplants with an appropriate human corneal endothelial cell density as a prerequisite for corneal function, several tissue engineering techniques have been developed to generate transplantable endothelial cell sheets. These approaches range from the use of natural membranes, biological polymers and biosynthetic material compositions, to completely synthetic materials as matrices for corneal endothelial cell sheet generation. This review gives an overview about currently used materials for the generation of transplantable corneal endothelial cell sheets with a special focus on thermo-responsive polymer coatings.
Anterior corneal cellular and structural abnormalities begin early in the course of Fuchs dystrophy, before the onset of clinically evident edema. The chronicity of these changes can explain their incomplete resolution after endothelial keratoplasty, and understanding the onset of these may help to …

Yet another issue with any P-IOL is endothelium cell loss. A certain amount of endothelial cells need to remain healthy to keep the cornea nourished. We all lose endothelial cells as part of the aging process, but virtually all studies show that all P-IOLs induce endothelial cell loss and accelerate loss in the ensuing years. Our organization argued strongly for the FDA to recognize this issue and the currently FDA approved method is for the doctor to take a count of the endothelial cells in a square millimeter and compare this count to a sliding scale of anticipated loss and expected time the P-IOL will be implanted. If you dont have enough cells to start, the P-IOL is contraindicated. At some point in time the number of cells will be diminished to where safety is a concern and the P-IOL will need to be removed. What fries my eggs is that very few surgeons implanting the P-IOLs are doing the preoperative endothelial cell count and even fewer have requiring the patient return on a regular ...
Laparoscopic surgery provides excellent visualization of the abdominal cavity through a minimally invasive technique.

Diabetic retinopathy is one of the leading causes of vision loss in industrialized countries. Despite recent advances, the biochemical basis for the development of this diabetic complication is uncertain. Although retinal circulation is unique in that it is readily observable noninvasively, retinal tissue is extremely difficult to study in humans because of the problems inherent in obtaining fresh, appropriate biopsy material. Moreover, because of the difficulties in working with animal models of diabetic retinopathy, such as the dog, many investigators have turned to cell-culture models, especially those using primary cultures of retinal capillary endothelial cells and pericytes. Diabetic retinopathy involves both morphological and functional changes in the retinal capillaries. Morphological changes include basement membrane thickening and pericyte disappearance; functional changes include one important early change-increased permeability-which may be attributable to endothelial cell changes ...
Coaxial microphacoemulsification performed through a 2.2 mm incision is a new technique available to cataract surgeons skilled in phacoemulsification. The technique affords patients the combined benefits of ultra-small incision surgery and conventional foldable IOLs, announced Robert H. Osher, MD, professor of ophthalmology, University of Cincinnati College of Medicine, and medical director emeritus, Cincinnati Eye Institute, Cincinnati, Ohio, USA.
Improvements in cataract surgery mean the procedure is faster and safer than ever before, allowing ophthalmologists to perform operations more quickly. The rise in productivity has led to increased incomes for surgeons, but has improved efficiency led to lower costs to the health system?. Over the past 30 years, cataract surgery has undergone huge advances. Dr. Guillermo Rocha, an ophthalmologist in Manitoba, recalls that his first surgery, in 1990, required a 10 mm incision to remove the cataract and replace the lens, followed by sutures. Now he makes an incision smaller than 2 mm, sometimes using a laser, destroys the cataract using ultrasound, inserts a folding lens, and allows the incision to heal on its own.. New technologies and techniques have transformed the operation from an inpatient procedure requiring months of recovery and follow-up to an outpatient one that allows patients to return to their normal lives within days. I have operated on surgeons that have then gone back to work the ...
Study design. The CCLM model in nude mice has been previously established (11). Washed colon-cancer cells, exceeding 95% cell viability by trypan blue dye exclusion were inoculated into nude mice. HT29 cells (1×106) were subcutaneously injected into the bilateral flanks. Once tumor growth reached 10 mm in diameter (in approximately 1-2 weeks), tumors were harvested and cut into small fragments. After anesthesia was administered, a 1 cm skin incision was made on the upper abdomen through the skin, fascia and peritoneum and the liver was exposed. A 5-mm incision was made in the left lobe of the liver, and a 3 mm tumor fragment was implanted into the liver. Fixation of the tumor was confirmed at 7 days post-implantation via midline laparotomy after the mouse was anesthetized (Figure 1).. Indocyanine green.

A horizontal ellipse is drawn on the skin using a skin marker, with the main axis aligned with the submental crease. Between 3.6 ml and 5.4 ml of local anaesthetic is infiltrated subcutaneously into the demarcated area. Next, using a scalpel, an incision is made in the demarcated area to eliminate the skin and subcutaneous tissue and reach the plane of the platysma muscle. After this, a skin marker is used to mark the muscular tissue of the platysma with two anterior-base triangles. A third posterior-base triangle is formed between the two that have already been described. This central triangle of the platysma muscle is resected and eliminated ( Fig. 2 ). Next, the central part of the area is dissected in search of the bone plane of the edge of the mandible. A 4-mm incision is made on the mentalis muscle above its lower insertion, leaving sufficient remaining muscle tissue so that they can be repositioned and sutured after having been detached.

Endoscopic spinal surgery is a highly effective new technique used to treat herniated discs, spinal stenosis, bone spurs, and slipped vertebrae. Developed by Dr. Sebastian Ruetten, a highly respected Germany physician and Head of the Department of Spine Surgery and Pain Therapy at St. Anna Hospital in Germany, the procedure involves an endoscope being inserted through a very small (7.9 mm) incision. A camera at the end of the endoscope allows the surgeon to identify and remove the affected nerves without causing any surgical trauma to the surrounding tissue. This technique reduces patient recovery time and reduces the risk of complications after surgery ...

Regular cervical screening is the best way to identify abnormal changes in the cells of the cervix at an early stage.. Women who are 25-49 years of age are invited for screening every three years. Women who are 50-64 years of age are invited every five years. For women who are 65 years of age or older, only those who havent been screened since they were 50, or those who have had recent abnormal tests, are offered screening.. Make sure that your GP surgery has your up-to-date contact details, so that you continue getting screening invitations.. Its important that you attend your cervical screening tests, even if youve been vaccinated for HPV, because the vaccine doesnt guarantee protection against cervical cancer.. If youve been treated for abnormal cervical cell changes, youll be invited for screening more frequently for several years after treatment. How regularly you need to go will depend on how severe the cell change is.. Although it can identify most abnormal cell changes in the ...

TY - JOUR. T1 - Corneal endothelial cell analysis using two non-contact specular microscopes in healthy subjects. AU - Garza-Leon, Manuel. PY - 2016/8/1. Y1 - 2016/8/1. N2 - To compare specular microscopy values obtained using the Perseus (CSO, Italy) and the Nidek CEM-530 (NIDEK Co., Ltd. Japan) specular microscopes. This prospective study used specular microscopy to examine sixty eyes from thirty healthy subjects (29.83 ± 9.41 years; range 18-79 years). This was done with both the Nidek CEM-530 and the Perseus on three occasions and results were evaluated by one independent observer. Measurement differences between instruments and agreement between devices were determined. The endothelial cell sample was larger with the Perseus than with the CEM-530 (235.92 ± 38.26 vs. 184.38 ± 43.88, respectively) with a statistically significant difference (P = 0.001). Mean endothelial cell density (ECD) with the Perseus and CEM-530 was 2692.75 ± 306.66 and 2556.47 ± 257.38 cells/mm 2 (P = 0.001), ...
Dysfunction of the corneal endothelium reduces the transparency of the cornea and can cause blindness. Because corneal endothelial cells have an extremely limited proliferative ability in vivo, treatment for corneal endothelial dysfunction involves the transplantation of donor corneal tissue. Corneal endothelium can also be restored via intraocular injection of endothelial cells in suspension after their expansion in vitro. Yet, because quality assessment during the expansion of the cells is a destructive process, a substantial number of the cultured cells are lost. Here, we show that the spring constant of the effective interaction potential between endothelial cells in a confluent monolayer serves as a biomarker of the quality of corneal endothelial cells in vitro and of the long-term prognosis of corneal restoration in patients treated with culture-expanded endothelial cells or with transplanted corneas. The biomarker can be measured from phase contrast imaging in vitro and from specular microscopy
Specular microscopy is a non-invasive photographic technique that allows you to visualize and analyse the corneal endothelium. This test is used to monitor the number, density, and quality of endothelial cells that line the back of the cornea. A microscope magnifies the cells thousands of times and the image is captured with a camera or video camera. The number of cells within one square millimeter are counted and recorded. The endothelium of a young, ten-year-old, healthy cornea has approximately 3,500 cells in each square millimeter. Normal aging causes the cells to gradually decrease over time. By age 60, most people have approximately 2,500 cells per square millimeter.. ...

Purpose: To evaluate the use of Pentacam densitometry maps in conjunction with a new laboratory protocol as a method to measure differences in UVA-RF crosslinking induced changes in whole globe porcine eyes.. Methods: 18 fresh whole globe porcine eyes were obtained ,24 hours postmortem in saline on ice from Sioux-Preme (Sioux City, IA). Epithelium was removed with a dull blade, and globes were soaked in Blood Bank Buffered Saline (Fisher Scientific, Agawam MA) for ,20 minutes at 37°C. Globes were mounted on a holder and an intraocular pressure of 30mmHg was applied to the globe through a cannula. Drops of 0.1% Riboflavin with 0.25%HPMC were applied to the corneas every 2 minutes for a total of 15 minutes at 37°C. The corneas were aligned to a Pentacam HR (Oculus Optikgeräte GmbH) outfitted with a 475nm (±25nm) notch filter to eliminate fluorescence saturation. Three pre-illumination images were acquired for each cornea. Avedros KXL-II (Avedro, Inc. Waltham MA) was used to illuminate a 4mm ...

An advantage to using a cell reference in the COUNTIF criteria is that the result will automatically update, if the value in the referenced cell changes. In the screenshot below, you can see that the passing score has been increased from 50 to 70. Because the Passed formula uses a reference to cell F5, the count is automatically updated. The Failed formula has the passing score of 50 typed into the criteria, so that value would have to be changed, before the result is updated.. ...
