05). Among the four quadrants, only the inferior nasal (IN) quadrant showed no difference in microvascular density between mild and moderate groups. Ridge regression indicated that microvascular density values in all three layers were more strongly correlated with axial length (AL) (scaled estimates -0.139, -0.103, -0.154; all p < 0.001) than with spherical equivalent (SE) (scaled estimates -0.052, -0.096, -0.057; all p < 0.05).

We characterized a stepwise and quadrant alteration of retinal microvascular density from mild to extreme myopia, which was more strongly affected by axial elongation, although both AL and SE were meaningful indicators.

A variety of treatment strategies have been proposed for macular holes that persist or recur after surgery, and the debate about the best re-treatment approach is ongoing. To allow for a comparison with alternative surgical therapies, we assessed the anatomical and functional outcome of atemporary tamponade with conventional silicone oil in persistent or recurrent full-thickness macular holes.

We retrospectively investigated consecutive patients with full-thickness macular holes that persisted or recurred following vitrectomy with internal limiting membrane peeling and gas tamponade. All patients received re-treatment by temporary tamponade of silicone oil and were allowed free postoperative positioning. Cell Cycle inhibitor Anatomical closure rate was assessed by optical coherence tomography, and change of best-corrected visual acuity (BCVA) was analyzed.

A total of 33 eyes of 33 consecutive patients were included. Macular hole closure following silicone oil tamponade was achieved in 30 of 33 eyes (90.9%). Median BCVA improved from 1.00 logMAR (interquartile range, 0.60-1.00) to 0.65 logMAR (0.49-1.00; p = 0.010) after silicone oil removal. In patients with macular hole closure, 61.3% exhibited functional improvement with median BCVA changing from 1.00 logMAR (0.70-1.00) to 0.60 logMAR (0.49-1.00; p = 0.0005). Mean minimal linear diameter of macular holes before primary surgery was 391.0 µm (±137.8; range 133-630), and 48.5% of macular holes were >400 µm in diameter.

Treatment of persistent or recurrent full-thickness macular holes by temporary conventional silicone oil tamponade without postoperative positioning results in a high closure rate and a significant mean improvement of visual acuity.

Numerous 2OGDDs are recurrently dysregulated in cancer. Moreover, cancer-specific metabolic changes, such as those that occur subsequent to mutations in the genes encoding succinate dehydrogenase, fumarate hydratase or isocitrate dehydrogenase, can dysregulate specific 2OGDDs. This latter observation suggests that the role of 2OGDDs in cancer extends beyond cancers that harbour mutations in the genes encoding members of the 2OGDD superfamily. Herein, we review the regulation of 2OGDDs in normal cells and how that regulation is corrupted in cancer.Blood pressure (BP) is influenced by various factors, and it is known that temperature and BP have a negative relationship. However, few reports have examined the relationship between BP and temperature throughout the day in the same participant over time. Therefore, this study aimed to investigate the relationship between BP and temperature in the morning and evening in the same participants during a time period of ~1 year. In total, 401 participants, who participated in a community-based health checkup survey in Tarumizu, Japan, were enrolled. Five participants were excluded due to missing data. All participants measured their BP and the room temperature at home using a blood pressure monitor (HEM-9700T, OMRON Healthcare, Kyoto, Japan). The mean systolic BP (SBP) and diastolic BP (DBP) in the morning were significantly higher than the mean of the measurements taken in the evening (SBP morning vs. evening 128 ± 15 mmHg vs. 122 ± 14 mmHg, P  less then  0.0001; DBP morning vs. evening 77 ± 10 mmHg vs. 72 ± 8 mmHg, P  less then  0.0001). Using a linear mixed model with participants as a random effect, SBP and DBP were significantly associated with temperature in both the morning and evening. In the morning, in almost every month except July, a significant association between SBP and temperature was observed. However, there was a significant relationship between evening BP and temperature in all months. In conclusion, BP was significantly related to temperature in both the morning and evening during the year-long study. Furthermore, BP and temperature were significantly associated in all months except morning measurements in July.Herpesviruses are ubiquitous, double-stranded DNA, enveloped viruses that establish lifelong infections and cause a range of diseases. Entry into host cells requires binding of the virus to specific receptors, followed by the coordinated action of multiple viral entry glycoproteins to trigger membrane fusion. Although the core fusion machinery is conserved for all herpesviruses, each species uses distinct receptors and receptor-binding glycoproteins. Structural studies of the prototypical herpesviruses herpes simplex virus 1 (HSV-1), HSV-2, human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) entry glycoproteins have defined the interaction sites for glycoprotein complexes and receptors, and have revealed conformational changes that occur on receptor binding. Recent crystallography and electron microscopy studies have refined our model of herpesvirus entry into cells, clarifying both the conserved features and the unique features. In this Review, we discuss recent insights into herpesvirus entry by analysing the structures of entry glycoproteins, including the diverse receptor-binding glycoproteins (HSV-1 glycoprotein D (gD), EBV glycoprotein 42 (gp42) and HCMV gH-gL-gO trimer and gH-gL-UL128-UL130-UL131A pentamer), as well gH-gL and the fusion protein gB, which are conserved in all herpesviruses.
