Effects of Ox-LDL on Macrophages NAD(P)H Autofluorescence Changes by Two-photon Microscopy

Ox-LDL uptakes by macrophage play a critical role in the happening of atherosclerosis. Because of its low damage on observed cells and better signal-to- background ratio, two-photon excitation fluorescence microscopy is used to observe NAD(P)H autofluorescence of macrophage under difference cultured conditions- bare cover glass, coated with fibronectin or poly-D-lysine. The results show that the optimal condition is fibronectin coated surface, on which, macrophages profile can be clearly identified on NAD(P)H autofluorescence images collected by two-photon microscopy. Moreover, different morphology and intensities of autofluorescence under different conditions were observed as well. In the future, effects of ox-LDL on macrophages will be investigated by purposed system to research etiology of atherosclerosis.Comment: Submitted on behalf of TIMA Editions (http://irevues.inist.fr/tima-editions

A Pilot Study of the Short Term Effectiveness and Safety of Amniotic Fluid in Severe Dry Eye Disease

The aim of this study was to evaluate if amniotic fluid (AF) mixed with artificial tears or soaked with a soft contact lens (SCL) as a treatment for severe dry eye disease (DED) would improve its signs or symptoms. In this retrospective pilot study 22 consecutive eyes of 11 patients with level 3 DED classified by DEWS 1 (Dry Eye WorkShop 1 2007), were included in the study between June 1 and September 30 in 2017. The study was conducted before DEWS II (Dry Eye WorkShop II 2017), which was published in October 2017. Therefore, DEWS II was not adopted for this study. Soft Contact Lens Acuvue Oasys of Plano with 8.8 base curve and 14 mm diameters by Johnson and Johnson were used to soak in FloGraft, which is an AF, for 30 minutes before placing in 12 eyes in Group 1. The contact lenses were placed in the left eye for 1 week. In Group 2, 10 eyes used 6 mL of artificial tears mixed with 0.25 mL of AF, which were applied to the eye four times a day for 1 week. No other eye medications were used. The eyes that were included had diffuse punctate staining and fast tear breaking times of <5 seconds with severe ocular symptoms (DEWS 1 level 3-4). Photos of fluorescein stain corneas before the treatment and 1 week after the treatment were used to compare the distribution of punctate staining as the objective outcomes for signs. Several questions adopted from the Ocular Surface disease Index (OSDI) about subjective symptoms before and after the treatment were asked, and documented on the chart. Improvement either in symptoms or signs or both of DED after 1 week at follow-up examination was recorded. Group 1, with SCL 46% had improvement after 1 week and Group 2, with artificial tears 50% had improvement after 1 week. Improvement means either symptom relief or comparatively decreased distribution of punctate staining on the cornea or both. No cases had inflammation, infection, irritation or blurred vision. We concluded that FloGraft as an AF can safely improve the symptoms or the signs of severe DED either as a mix with artificial tears or soaked with SCL by about 50% in this case series without evidence of irritation, inflammation or blurred vision in the short term

The Waveform Fluctuation and the Clinical Factors of the Initial and Sustained Erythropoietic Response to Continuous Erythropoietin Receptor Activator in Hemodialysis Patients

Objectives. Erythropoiesis-stimulating agents (ESA) are the main treatment for anemia in hemodialysis (HD) patients. We evaluated factors determining the response after treatment of a new ESA (continuous erythropoietin erythropoietin receptor activator (CERA)). Methods. 61 HD patients were classified by their response at two different timings. First, patients whose hematocrit (Hct) increased 1.5% in the first week were defined as initial responders (IR, n = 16). We compared several parameters between IR and the rest of the study subjects (non-IR, n = 45). Second, patients whose Hct increased 2% in the 4th week were defined as sustained responders (SR, n = 12), and we did a similar comparison. Results. The Hct showed a waveform fluctuation. Compared with the rest, IR had significantly lower platelet counts and higher levels of ferritin, total protein, total bilirubin, and serum sodium, while SR had significantly lower levels of C-reactive protein and low-density lipoprotein (All P < 0.05). In comparison with the rest, higher Hct persisted for 10 weeks in SR but only for two separate weeks (the 1st and 7th week) in IR. Conclusions. The initial and sustained erythropoietic responses are independent from each other and are associated with different factors. Treatment focusing on these factors may improve the response

Can Email Be Evidence for Adultery in Criminal Law Cases? A Philosophical and Legal Explication of the Court’s Evaluation of Evidence through Inner Conviction

Adultery in Taiwan’s Criminal Law is defined as sexual intercourse between a married person and someone other than his/her spouse, however, a person cannot be accused of adultery unless substantial evidence of sexual intercourse is found. Until recently, electronically transmitted messages were not considered substantive proof of adultery, but new cases have acknowledged the validity of internet and MSN messages, representing a major change in the direction in Taiwan’s legal practice. The question we raise here is whether internet messages should be considered substantial evidence in current legal principle and practice. In an attempt to address this thorny question, we conduct an analysis of contemporary Taiwanese case law concerning adultery. This study is also aided by the application of probability theories of evidence in logical positivism to illustrate the legal status of internet evidence. Adopting this interdisciplinary approach, this paper aims to better illuminate the pressing problems of whether and how internet evidence can play a significant role in establishing adultery

Human parvovirus B19 nonstructural protein NS1 enhanced the expression of cleavage of 70 kDa U1-snRNP autoantigen

<p>Abstract</p> <p>Background</p> <p>Human parvovirus B19 (B19) is known to induce apoptosis that has been associated with a variety of autoimmune disorders. Although we have previously reported that B19 non-structural protein (NS1) induces mitochondrial-dependent apoptosis in COS-7 cells, the precise mechanism of B19-NS1 in developing autoimmunity is still obscure.</p> <p>Methods</p> <p>To further examine the effect of B19-NS1 in presence of autoantigens, COS-7 cells were transfected with pEGFP, pEGFP-B19-NS1 and pEGFP-NS1K334E, a mutant form of B19-NS1, and detected the expressions of autoantigens by various autoantibodies against Sm, U1 small nuclear ribonucleoprotein (U1-snRNP), SSA/Ro, SSB/La, Scl-70, Jo-1, Ku, and centromere protein (CENP) A/B by using Immunoblotting.</p> <p>Results</p> <p>Significantly increased apoptosis was detected in COS-7 cells transfected with pEGFP-B19-NS1 compared to those transfected with pEGFP. Meanwhile, the apoptotic 70 kDa U1-snRNP protein in COS-7 cells transfected with pEGFP-B19-NS1 is cleaved by caspase-3 and converted into a specific 40 kDa product, which were recognized by anti-U1-snRNP autoantibody. In contrast, significantly decreased apoptosis and cleaved 40 kDa product were observed in COS-7 cells transfected with pEGFP-NS1K334E compared to those transfected with pEGFP-B19-NS1.</p> <p>Conclusions</p> <p>These findings suggested crucial association of B19-NS1 in development of autoimmunity by inducing apoptosis and specific cleavage of 70 kDa U1-snRNP.</p

Platform Deformation Phase Correction for the AMiBA-13 Coplanar Interferometer

[[abstract]]We present a new way to solve the platform deformation problem of coplanar interferometers. The platform of a coplanar interferometer can be deformed due to driving forces and gravity. A deformed platform will induce extra components into the geometric delay of each baseline and change the phases of observed visibilities. The reconstructed images will also be diluted due to the errors of the phases. The platform deformations of The Yuan-Tseh Lee Array for Microwave Background Anisotropy (AMiBA) were modeled based on photogrammetry data with about 20 mount pointing positions. We then used the differential optical pointing error between two optical telescopes to fit the model parameters in the entire horizontal coordinate space. With the platform deformation model, we can predict the errors of the geometric phase delays due to platform deformation with a given azimuth and elevation of the targets and calibrators. After correcting the phases of the radio point sources in the AMiBA interferometric data, we recover 50%-70% flux loss due to phase errors. This allows us to restore more than 90% of a source flux. The method outlined in this work is not only applicable to the correction of deformation for other coplanar telescopes but also to single-dish telescopes with deformation problems. This work also forms the basis of the upcoming science results of AMiBA-13.[[notice]]補正完畢[[journaltype]]國外[[incitationindex]]SCI[[ispeerreviewed]]Y[[booktype]]電子版[[booktype]]紙本[[countrycodes]]US

A comparison of three different corneal marking methods used to determine cyclotorsion in the horizontal meridian

During toric intraocular lens (IOL) implantation, surgeons must take particular care to ensure that inaccurate preoperative measurement and intraoperative misalignment do not cause unexpected postoperative residual astigmatism. This retrospective, comparative case series study aimed to analyze the rotational deviation, or cyclotorsion, of three corneal marking methods: VERION digital marker (VDM; reference), horizontal slit beam marking (HSBM), and subjective direct visual marking (SDVM) on the table (using a bevel knife tip). Subjects included 81 eyes of 61 patients (mean age: 65.70±13.14 years; range: 32–91 years) undergoing scheduled cataract surgery. A preoperative reference image was taken of each eye. Subsequently, a slit lamp with the light beam turned to the horizontal meridian was used to align the seated patient’s head, and two reference marks were placed at the 3- and 9-o’clock positions of the corneal limbus using a 27-gauge needle and marking pen (HSBM). Upon transfer to the surgical table, the VDM was used to display a real-time dial scale on the patient’s eye, with the entrance of the temporal clear corneal incision (CCI) at 0° (horizontal meridian). Simultaneously, a bevel knife tip was used to create a marker based on the surgeon’s visual determination of the temporal 0° point (SDVM). We used the VDM to quantitatively evaluate the accuracy of axis alignment via deviation from the horizontal reference meridian. Compared with the reference meridian, the SDVM (−3.46°±7.32°, range: −18° to 13°) exhibited greater average relative cyclotorsion versus the HSBM (0.41°±4.92°, range: −10° to 10°). Furthermore, the mean average misalignment was significantly less in the HSBM group versus the SDVM group (t=4.179, P<0.001). The VDM is likely a reliable marking method, similar to the HSBM. In contrast, the SDVM is not entirely reliable. The VDM usage may prevent inaccurate preoperative manual marking during toric IOL implantation
