001). In comparison with the control group, it remained on a higher level after the operation (p < 0.001) and the next day (p = 0.03). The patients with AKI had more postoperative bleeding and received more blood transfusion.
VitD pretreatment was unable to impose any changes in the incidence of AKI and the urinary level of renal biomarkers. However, high-dose administration of VitD may improve the anti-inflammatory state before and after the operation. Further studies are needed to assess the renoprotective effect of VitD on coronary surgery patients.

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) syndrome is a recently described chronic inflammatory disease of the central nervous system. There are few reports of CLIPPERS in the Chinese population to date. We summarized the clinical characteristics of 6 CLIPPERS patients to deepen the understanding of this disease.
The clinical manifestations and treatment of 6 CLIPPERS patients confirmed by pathology or clinical diagnosis in our hospital were retrospectively analyzed.
The common clinical manifestations included ataxia, dysarthria, diplopia, dysphagia, dizziness, cognitive impairment, facial paresthesia, and paralysis. Most of the lesions showed typical symmetric "pepper powder"-like dot and nodular enhancement centered in the pontine and cerebellum except 1 patient with unilateral nodular enhancement. The brain histopathological examination of the 5 biopsied patients indicated that, with the exception of patient 4 with no lymphocyte infiltratinal diagnosis of CLIPPERS. In addition, the lymphocytic infiltration in the lesions of CLIPPERS may be dominated by CD20+ B cells instead of CD3+ T cells.
To investigate longer-term functional and morphological outcomes and their predictors in diabetic macular edema (DME) following a treat and extend regimen (TER) without loading dose under ranibizumab.
Patient data were reviewed and analyzed retrospectively over a period of 24 months after initiation of TER. Best-corrected visual acuity (BCVA), treatment frequency as well as quantitative and qualitative Spectral-domain Optical Coherence Tomography parameters were assessed.
118 eyes of 87 patients were included. A mean of 9.742.13 injections in the first and 7.632.29 in the second year were applied. There were significant gains of BCVA and reductions in central retinal thickness from baseline to month 12 and 24 (all p<0.001). Percentage of eyes with an intact inner-/outer segment (IS/OS) junction increased from 15.3% at baseline to 42.1% at month 24 (p<0.001). An intact IS/OS junction at baseline increased the probability of having a dry retina after 12 months by 79.3% (p=0.017) and after 24 months by 88.1% (p=0.040). Less IS/OS disruption at baseline predicted longer maximum recurrence-free treatment intervals at 2 years (r=-0.345, p<0.001) and better BCVA at one year (r=-0.347, p<0.001). Baseline bigger intraretinal cysts were associated with more IS/OS disruption at 24 months (r=0.305, p=0.007). Younger age and lower BCVA at baseline were predictive for a higher BCVA gain at 24 months (p=0.046, p<0.001).
Ranibizumab applied in a TER without loading dose in DME significantly improves visual acuity and retinal anatomical structure throughout two years. The evaluated predictors might help to guide routine clinical treatment in DME.

To date, only 8 species have been karyotyped, showing high levels of diploid number variation, which allowed clustering species in chromosome number groups 2n = 24 (Aplastodiscus perviridis group), 2n = 22 (Aplastodiscus albofrenatus group), 2n = 20, and 2n = 18 (both within Aplastodiscus albosignatus group). This study aims to report karyotypic information on 4 species from the last 2 groups using classical and molecular cytogenetic techniques and hypothesize chromosomal evolutionary trends within the species groups. Aplastodiscus weygoldti showed 2n = 22; Ag-NOR and FISH 18S rDNA signals were located in the interstitial region of the short arms of chromosome pair 6. Aplastodiscus cavicola, Aplastodiscus sp. 4, and Aplastodiscus sp. 6 showed 2n = 18; Ag-NOR and FISH 18S rDNA bands were located in the terminal region of the long arm of chromosome pair 9. Our results support multiple and independent chromosome fusion events within Aplastodiscus, including a new chromosome fission event. Ag-NOR and FISH 18S rDNA patterns were restricted to the small chromosome pairs, similar to the other species within this genus, and confirm overall chromosome morphology conservation among the genera of Cophomantinae.
Diabetic retinopathy (DR) is a sight-threatening complication of diabetes mellitus (DM). Oxidative stress generated on account of hyperglycemic state may lead to retinal abnormalities including DR.
To evaluate the status of antioxidant enzymes -superoxide dismutase (SOD) and catalase (CAT); with different stages of DR severity in subjects with type 1 and type 2 DM.
The cross-sectional study enrolled 148 subjects with type 1 DM (n=17); type 2 DM (n=96) and non-diabetes controls (n=35). NSC 74859 purchase Subjects with DM were divided into two subgroups based on DR severity (mild-to-severe non-proliferative DR and proliferative DR [PDR]) and Serum glycated hemoglobin (HbA1c), lipid profile, SOD and CAT were estimated.
Both SOD and CAT levels were lower in diabetes subjects than non-diabetic controls. A significant positive correlation was found between HbA1C level and severity of DR (P<0.0001). Levels of SOD and CAT varied significantly with DR severity in both diabetic groups at p<0.05. Furthermore, levels of SOD and CAT was found to decrease significantly (P<0.
