Additionally, cholesterol showed astoundingly opposite contribution to the partitioning of TAM into the LUVs, as its Kp value reduced in DPPC/Chol bilayer yet increased in DPPG/Chol liposomes. CONCLUSION Ionic strength and cholesterol play a noteworthy role in regulation of TAM partitioning into lipid membranes as they could obstruct or promote such action.PURPOSE To correlate choriocapillaris (CC) flow deficits (FD) in eyes with geographic atrophy (GA) at various distances from the border of the GA lesion with yearly enlargement rate (yER) of GA. METHODS In this retrospective study, spectral domain optical coherence tomography (SD-OCT) and SD optical coherence tomography angiography (OCTA) images were collected from patients with GA, who were imaged at Doheny Eye Centers between 2016 and 2018, using the Cirrus HD-OCT (Carl Zeiss Meditec, Dublin, CA). All enrolled patients had one baseline 6 × 6 mm OCTA scan and two 6 × 6 mm SD-OCT cubes, one at baseline and one at a follow-up visit at least 12 months later. The border of the GA was manually outlined on the en face OCT fundus image and the yER was calculated after square root transformation. A grid composed of 100-μm-wide successive concentric rings was created around the GA lesion on the OCTA CC slab using ImageJ and the FD% was calculated from the binarized image. FD% from each ring was correlated with the yER of GA. RESULTS Thirty eyes of 22 patients were included in the study. The mean yER was 0.2 ± 0.15 mm. The FD% in the first five rings (from 0 to 500 μm from the border of GA) was significantly correlated with the yER. However, there was no statistically significant correlation between the yER and CC FD% beyond 500 μm from the GA lesion. CONCLUSIONS Only the choriocapillaris FD% in the 500-μm region immediately surrounding GA lesions appears to predict the rate of enlargement of these lesions.PURPOSE To describe the surgical procedures, outcomes, and complications of a novel technique of subretinal injection of ranibizumab (SRR). METHODS Between September 2012 and September 2018, 37 eyes of 26 consecutive children with vascularly active total retinal detachments in 1 or both eyes treated with SRR as primary treatment were included in this retrospective study. All included eyes received subretinal injection of ranibizumab (0.25 mg/ 0.025 ml). Data included demographics, ocular examination, and anatomic outcomes, following treatment and complications of eyes after SRR were collected. RESULTS Eleven patients had bilateral SRR injections and 15 had monocular SRR injection. Thirteen patients were diagnosed as retinopathy of prematurity. Of all patients, the mean gestational age was 34.5 ± 5.1 weeks (range 29.6~40.7 weeks), and birth weight was 2328.1 ± 1083.9 g (range 940~3900 g). On 1-week postoperative follow-up, vascular activity decreased in all 37 eyes (100%). HL 362 cAMP activator On the 1-month postoperative follow-up, vascular activity decreased but remained in 24 eyes (24/35, 68.6%) of 16 patients and vanished in 11 eyes (11/35, 31.4%) of 9 patients. No eye needed a secondary anti-VEGF therapy. Local subconjunctival hemorrhage was noted in two eyes (2/37, 5.4%). Localized wound leakage of subretinal fluid was also noted in one eye (1/37, 2.7%). CONCLUSIONS In this very limited study, we showed that SRR in vascularly active advanced pediatric vasoproliferative disorders with total retinal detachments is effective and promising, although more extensive controlled trials will be needed to confirm its safety and efficacy.The Philippine tarsier (Tarsius syrichta) is a charismatic species that is threatened by illegal hunting and deforestation. Although they occur in forest and disturbed habitats, ecological information about them is still considerably lacking, which consequently hampers our ability to effectively protect tarsiers from further endangerment. Here, we characterized a 36-ha forest fragment in Mindanao Island where a population of tarsiers persist, and assessed the factors that could have influenced their distribution within the area. We sampled trees (> 1 cm DBH) within 10 × 10-m sampling plots (N = 54), which were established within 1-ha grids (N = 32) and locations where tarsiers were captured (N = 22). The habitat was characterized as a regenerating forest over limestone, with a generally homogeneous structure in terms of tree species richness, abundance, mean DBH, and height. In both sampling plots, we found an abundance of trees below 5 cm in DBH (> 50%) and between 2.6 and 5 m in height (> 40%), which, accordingly, the tarsiers appeared to prefer to use when foraging or sleeping. Lianas were among the most important features of the forest, possibly being a keystone structure in such habitats. Community assemblage, species richness, and mean height of trees, as well as distance to the forest edge, were found to be significant factors that influenced tarsier distribution in the fragment. Our study provides basic yet critical information on the habitat and ecology of Philippine tarsiers in Mindanao, and highlights the importance of forest fragments with rich flora diversity to the survival of the species.RATIONALE The regular consumption of very small doses of psychedelic drugs (known as microdosing) has been a source of growing media and community attention in recent years. However, there is currently limited clinical and social research evidence on the potential role of microdosing as therapies for mental and substance use disorders. OBJECTIVES This paper examined subjective experiences of microdosing psychedelics to improve mental health or to cease or reduce substance use, and examined sociodemographic and other covariates of perceived improvements in mental health that individuals attributed to microdosing. METHODS An international online survey was conducted in 2018 and examined people's experiences of using psychedelics for self-reported therapeutic or enhancement purposes. This paper focuses on 1102 respondents who reported current or past experience of psychedelic microdosing. RESULTS Twenty-one percent of respondents reported primarily microdosing as a therapy for depression, 7% for anxiety, 9% for other mental disorders and 2% for substance use cessation or reduction. Forty-four percent of respondents perceived that their mental health was "much better" as a consequence of microdosing. In a multivariate analysis, perceived improvements in mental health from microdosing were associated with a range of variables including gender, education, microdosing duration and motivations, and recent use of larger psychedelic doses. link2 CONCLUSIONS Given the promising findings of clinical trials of standard psychedelic doses as mental health therapies, clinical microdosing research is needed to determine its potential role in psychiatric treatment, and ongoing social research to better understand the use of microdosing as self-managed mental health and substance use therapies.Multi-date remotely sensed images comprising Landsat TM images of 1984, 1993 and 2003 and, Landsat OLI images of 2013 were used to reconstruct long-term changes in land cover in the Swartkops River Estuary by mapping changes in vegetation distribution over a period of ~ 30 years between 1984 and 2013. These images were complemented by high-resolution near-anniversary aerial photographs that were used as ancillary sources of ground truth during supervised classification of the Landsat images. Results of our investigation point to human-induced loss of biodiversity due to persistent encroachment of different development activities on terrestrial vegetation, substantial expansion of the salt marsh due to climate change-driven relative sea level rise and persistent increase in keystone salt marsh vegetation species notably Zostera capensis and Spartina maritima due to the combined influence of human-induced nutrient loading into estuarine water and relative sea level rise. These observations argue for the immediate need to embrace appropriately informed management interventions in order to enhance the sustainability of salt marsh ecosystems for the benefit of present and future generations.Pericyte loss and deficient vascular platelet-derived growth factor receptor-β (PDGFRβ) signaling are prominent features of the blood-brain barrier breakdown described in Alzheimer's disease (AD) that can predict cognitive decline yet have never been studied in the retina. Recent reports using noninvasive retinal amyloid imaging, optical coherence tomography angiography, and histological examinations support the existence of vascular-structural abnormalities and vascular amyloid β-protein (Aβ) deposits in retinas of AD patients. link3 However, the cellular and molecular mechanisms of such retinal vascular pathology were not previously explored. Here, by modifying a method of enzymatically clearing non-vascular retinal tissue and fluorescent immunolabeling of the isolated blood vessel network, we identified substantial pericyte loss together with significant Aβ deposition in retinal microvasculature and pericytes in AD. Evaluation of postmortem retinas from a cohort of 56 human donors revealed an early and progressive decrease in vascular PDGFRβ in mild cognitive impairment (MCI) and AD compared to cognitively normal controls. Retinal PDGFRβ loss significantly associated with increased retinal vascular Aβ40 and Aβ42 burden. Decreased vascular LRP-1 and early apoptosis of pericytes in AD retina were also detected. Mapping of PDGFRβ and Aβ40 levels in pre-defined retinal subregions indicated that certain geometrical and cellular layers are more susceptible to AD pathology. Further, correlations were identified between retinal vascular abnormalities and cerebral Aβ burden, cerebral amyloid angiopathy (CAA), and clinical status. Overall, the identification of pericyte and PDGFRβ loss accompanying increased vascular amyloidosis in Alzheimer's retina implies compromised blood-retinal barrier integrity and provides new targets for AD diagnosis and therapy.BACKGROUND Although thoracoscopic esophagectomy in the prone position (TEPP) has become a standard procedure for esophageal cancer surgery, upper mediastinal lymph node dissection (UMLND) on the left side remains an issue. We have recently developed a new standardized approach to left UMLND in TEPP based on the microanatomy of the membranes and layers with the aim of achieving quick and safe surgery. The purpose of this study was to establish and evaluate our new standardized procedure in left UMLND. PATIENTS AND METHODS Patients were divided into 2 groups a pre-standardization group (n = 100) and a post-standardization group (n = 100). Eventually, 83 paired cases were matched using propensity score matching. In our new standardized procedure, left UMLND was performed while focusing on the visceral sheath, vascular sheath, and the fusion layer between them using a magnified view. RESULTS The thoracoscopic operative time was significantly shorter (P  less then  0.001) in the post-standardization group [n = 83; 209.0 (176.0-235.0) min] than in the pre-standardization group [n = 83; 235.5 (202.8-264.5) min]. No significant differences were found in the number of mediastinal lymph nodes dissected or intraoperative blood loss between the two groups. There was a tendency for the total postoperative morbidity to decrease in the post-standardization group. Furthermore, the left recurrent laryngeal nerve palsy rate was significantly lower in the post-standardization group (18.1% to 8.7%, P = 0.015). CONCLUSION Microanatomy-based standardization contributes to safe and efficient left UMLND.
