Data Brief 2020; 29:105308. [PMID: 32154345 PMCID: PMC7056631 DOI: 10.1016/j.dib.2020.105308] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 02/07/2020] [Accepted: 02/13/2020] [Indexed: 11/17/2022] Open
Abstract
Watershed data, climate and stable data collected over a 16-year period from a network of 50 lakes in northeastern Alberta, are provided to allow for broader incorporation into regional assessments of environmental impacts, particularly hydrologic and geochemical processes under changing climate and land use development. Oxygen-18 and deuterium analyses of water samples are provided from late summer surveys of 50 lakes with varying land cover and permafrost conditions. Six sub-groups of lakes are represented, including Stony Mountains, West Fort McMurray, Northeast Fort McMurray, Birch Mountains, Caribou Mountains and Shield. This dataset includes 1582 isotopic analyses made on 791 water samples and 3164 isotope mass balance model outputs, as well as 800 lake/watershed parameters, 5600 climate parameters, and 800 modelled values for isotopic composition of precipitation used in the computations. Model data are provided to facilitate evaluation of transferability of the model for other applications, and to permit more sophisticated spatial analysis and intercomparison with geochemical and biological datasets. Details and further discussion on the isotope mass balance approach are provided in “Regional trends in water balance and runoff to fifty boreal lakes: a 16-year isotope mass balance assessment including evaluation of hydrologic drivers” [1]. Overall, the data are expected to be useful, in comparison with local and regional datasets, for water resource management and planning, including design of monitoring networks and environmental impact assessments for oil sands projects.

Abstract
We demonstrate a novel, to the best of our knowledge, refractive index (RI) sensor based on the Vernier effect in dual-microfiber coupler (MFC) structures. The sensor sensitivity was studied both theoretically and experimentally. The numerical results show that by tracing the wavelength shifts of the envelope formed by the Vernier effect, the sensitivity can be improved by several times compared to that obtained for normal coupler-based sensors. In this Letter, two MFCs with a width and free spectral range (FSR) of $\sim{3.5}\;{\unicode{x00B5} \rm m}$∼3.5µm and 6 nm, respectively, were fabricated. Based on the sensitivity of 5820 nm/RIU for a single coupler, we experimentally achieved an ultra-high sensitivity of 126,540 nm/RIU using dual MFCs by the Vernier effect in the RI range of 1.3350 to 1.3455, which shows good agreement with numerical simulations. The proposed all-fiber RI sensor has the advantages of high sensitivity and low cost and can find applications in chemical and biological detection as well as electronic/magnetic field measurement.

Abstract
Ectopic lymphatics form in bone and promote bone destruction in diseases such as Gorham-Stout disease, generalized lymphatic anomaly, and kaposiform lymphangiomatosis. However, the role lymphatics serve in normal bone development and repair is poorly understood. The objective of this study was to characterize bone development and fracture healing in mice that have a defect in the development of the lymphatic vasculature. We found that bones in wild-type adult mice and mouse embryos did not have lymphatics. We also found that bone development was normal in Vegfr3 (Chy/Chy) embryos. These mice do not have lymphatics and die shortly after birth. To determine whether lymphatics serve a role in postnatal bone development and fracture healing, we analyzed bones from Vegfr3 (wt/Chy) mice. These mice are viable and have fewer lymphatics than wild-type mice. We found that postnatal bone development and fracture healing was normal in Vegfr3 (wt/Chy) mice. Taken together, our results suggest that lymphatics do not play a major role in normal bone development or repair.

Abstract
We present cleared tissue Axially Swept Light-Sheet Microscopy (ctASLM), which enables isotropic, subcellular resolution, high optical sectioning capability, and large field of view imaging over a broad range of immersion media. ctASLM can image live, expanded, and both aqueous and organic chemically cleared tissue preparations. Depending on the optical configuration, ctASLM provides up to 260 nm axial resolution, an improvement over confocal and other reported cleared tissue light-sheet microscopes by a factor 3–10. We image millimeter-scale tissues with subcellular 3D resolution, which enabled us to automatically detect with computer vision multicellular tissue architectures, individual cells, synaptic spines, and rare cell-cell interactions.

Abstract
AIM To test the hypothesis that delayed menarche is associated with an increased microvascular complication risk among women with Type 1 diabetes. METHODS We studied the female participants of an ongoing prospective study of childhood-onset Type 1 diabetes diagnosed during the period 1950-1980. Of 325 women, we included data from 315 who had reached menarche by the study baseline (1986-1988) and who self-reported their age at menarche. Both cross-sectional and prospective analyses over the 25-year follow-up were used to assess the relationship of age at menarche with the prevalence, incidence and cumulative incidence of microvascular complications, comprising overt nephropathy, proliferative retinopathy and confirmed distal symmetric polyneuropathy. RESULTS In cross-sectional analyses at baseline, the odds of overt nephropathy increased 1.24 times (P=0.02) with each annual increase in age at menarche, and 3.2 times (P=0.009) in those with delayed menarche compared with women with normal menarche onset, after adjustment. Similarly, the cumulative incidence of overt nephropathy increased 1.16 times (P=0.01) with each older year of menarche and women with delayed menarche were at twofold increased risk of overt nephropathy (hazard ratio 2.30, P=0.001) compared with women with normal menarche onset. However, age at menarche was not significantly associated with either proliferative retinopathy or confirmed distal symmetric polyneuropathy after adjusting for covariates. CONCLUSIONS Age at menarche was significantly associated with the prevalence and cumulative incidence of overt nephropathy, but not with proliferative retinopathy or confirmed distal symmetric polyneuropathy in Type 1 diabetes. Women with delayed menarche may therefore be targeted for early screening and timely interventions to prevent the development of nephropathy.

Abstract
Traditional two-dimensional histological sections and microcomputed tomography remain to be the major tools for studying craniofacial bones despite the complicated spatial organization of craniofacial organs. Recently, our laboratory developed the Poly(Ethylene Glycol) Associated Solvent System (PEGASOS) tissue clearing method, which can efficiently render hard tissues, including bones and teeth fully transparent without losing endogenous fluorescent signals. Complete tissue transparency enables us to acquire three-dimensional (3D) images of craniofacial bone vasculature, osteogenesis utilizing various labeling strategies, thus to investigate the spatial relationship among different tissues during postnatal craniofacial development. We found out that during the early stage of postnatal development, craniofacial osteogenesis occurs throughout the entire craniofacial bones, including the periosteum, dura, bone marrow, and suture. After 3-4 weeks, craniofacial osteogenesis is gradually restricted to the suture region and remaining bone marrow space. Similarly, craniofacial bone vasculature gradually restricts to the suture region. Osteogenesis is spatially associated with vasculature during the entire postnatal development. Importantly, we demonstrated that in adult calvarial bones, Gli1+ mesenchymal stem cells were also spatially associated with the vasculature. These findings indicate that craniofacial bones share similar osteogenesis mechanism as the long bone despite their distinct osteogenic mechanisms. In addition, the PEGASOS tissue clearing method-based 3D imaging technique is a useful new tool for craniofacial research.

Abstract
Objective: To estimate the health-related quality of life (HRQOL) and health-adjusted life expectancy (HALE) which were associated with chronic non-communicable diseases (NCDs) in people from Guangdong province of China. Methods: Data on both NCDs prevalence and EuroQol-5 Dimensions-3 Levels measured HRQOL were gathered from the Fifth National Health Survey in Guangdong province, 2013. Logistic regression model and multiple linear regression model were employed to explore the impact of NCDs on HRQOL. Life expectancy (LE) and HALE were used to evaluate the comprehensive impact of chronic diseases on population health. Results: A total of 68 550 inhabitants were included in the analysis. Graded logistic regression showed that the impact of chronic diseases on all dimensions of quality of life was statistically significant after adjusting for social demographic characteristics. The greatest health impact was on the pain/discomfort health dimension [OR=4.48 (95%CI:4.20-4.77)], followed by anxiety/depression[OR=3.95 (95%CI: 3.62- 4.31)], daily activities [OR=3.69 (95%CI: 3.37-4.04)], mobility [OR=3.63 (95%CI: 3.34-3.94)]and ability on self-care [OR=3.30 (95%CI: 2.98-3.66)]. Losses of LE and HALE caused by NCDs were 12.7 and 14.6 years respectively while the overall expected gain was 3.8 years in HALE, when NCDs were taken away. Conclusions: Our data showed that NCDs had shortened the healthy life span of patients through reducing the HRQOL and also causing heavy disease burden on both patients with NCDs and the communities. Health-care related policies on NCDs need to be developed, for the elderly, in particular.

Abstract
OBJECTIVES Dental implants are major treatment options for restoring teeth loss. Biological processes at the implant-tissue interface are critical for implant osseointegration. Superior mechanical properties of the implant constitute a major challenge for traditional histological techniques. It is imperative to develop new technique to investigate the implant-tissue interface. MATERIALS AND METHODS Our laboratory developed the polyethylene glycol (PEG)-associated solvent system (PEGASOS) tissue clearing method. By immersing samples into various chemical substances, bones and teeth could be turned to transparent with intact internal structures and endogenous fluorescence being preserved. We combined the PEGASOS tissue clearing method with transgenic mouse line and other labelling technique to investigate the angiogenesis and osteogenesis processes occurring at the implant-bone interface. RESULTS Clearing treatment turned tissue highly transparent and implant could be directly visualized without sectioning. Implant, soft/hard tissues and fluorescent labels were simultaneously imaged in decalcified or non-decalcified mouse mandible samples without disturbing their interfaces. Multi-channel 3-dimensional image stacks at high resolution were acquired and quantified. The processes of angiogenesis and osteogenesis surrounding titanium or stainless steel implants were investigated. CONCLUSIONS Both titanium and stainless steel implants support angiogenesis at comparable levels. Successful osseointegration and calcium precipitation occurred only surrounding titanium, but not stainless steel implants. PEGASOS tissue clearing method provides a novel approach for investigating the interface between implants and hard tissue.

Abstract
Opaqueness of animal tissue can be attributed mostly to light absorption and light scattering. In most noncleared tissue samples, confocal images can be acquired at no more than a 100-µm depth. Tissue-clearing techniques have emerged in recent years in the neuroscience field. Many tissue-clearing methods have been developed, and they all follow similar working principles. During the tissue-clearing process, chemical or physical treatments are applied to remove components blocking or scattering the light. Finally, samples are immersed in a designated clearing medium to achieve a uniform refractive index and to gain transparency. Once the transparency is reached, images can be acquired even at several millimeters of depth with high resolution. Tissue clearing has become an essential tool for neuroscientists to investigate the neural connectome or to analyze spatial information of various types of brain cells. Other than neural science research, tissue-clearing techniques also have applications for bone research. Several methods have been developed for clearing bones. Clearing treatment enables 3-dimensional imaging of bones without sectioning and provides important new insights that are difficult or impossible to acquire with conventional approaches. Application of tissue-clearing technique on dental research remains limited. This review will provide an overview of the recent literature related to the methods and application of various tissue-clearing methods. The following aspects will be covered: general principles for the tissue-clearing technique, current available methods for clearing bones and teeth, general principles of 3-dimensional imaging acquisition and data processing, applications of tissue clearing on studying biological processes within bones and teeth, and future directions for 3-dimensional imaging.

Abstract
A novel design of nested optical fiber based multiple knot resonators is presented. The design consists of three knot resonators, two of which share a significant fraction of their optical path. The relationship between the knots' diameter ratio and the transmission spectrum is investigated. The output spectrum is theoretically analyzed using transfer matrix analysis and the calculated results exhibit good agreement with experimental results. The free spectral range (FSR) is varied by simply fine-tuning the diameter of the small knot. The periodic spectrum of this optical microfiber based photonic device has a number of applications in the sensing and communications field, e.g., optical interleavers, frequency combs, filters, and fiber lasers. This Letter demonstrates that the variation of the output spectrum can be implemented simply by changing the knot sizes and coupling coefficients.

Abstract
Objective:To investigate the experience of nasal Schwannoma in order to provide guidance for the diagnosis and treatment of the disease. Method:Clinicopathological data and follow-up results of nine patients, which histopathology proved nasal Schwannoma were collected and analyzed. Result:The patients were referred to our clinic due to the space-occupying symptoms or signs of tumour compression. There were no specific findings in imaging examination. The patients were treated by operation except a multiple Schwannoma patient.The recurrence after operation were rare. The main features of pathological diagnosis was a strong expression of S-100 protein. Conclusion:Nasal Schwannoma usually has no specific clinical manifestations. Imaging examination is valuable to the determination of surgical range and the diagnosis of benign and malignant diseases. The diagnosis depends on histologic examination. Surgery is the only effective treatment. The best surgical procedure selection hinges on the lesion location and the prognosis is excellent.

Abstract
BACKGROUND Several studies have examined sleep quality in the post renal transplant population of China, but few studies have actually confirmed the related psychosocial variables of sleep quality in renal transplant recipients with home care. OBJECTIVES This study investigates sleep quality and its related psychosocial variables among renal transplant patients. METHODS This is a cross-sectional study using a convenient sampling approach. Self-report questionnaires were applied to 485 renal transplant patients. All participants completed the General Data Questionnaire, the Pittsburgh Sleep Quality Index (PSQI), the Self-Rating Depression Scale, the Three-Dimensional Inventory of Character Strengths, and the Flourishing Scale. RESULTS A total of 438 valid questionnaires were included in the analysis. The global PSQI score was 5.86 (SD, 3.20), significantly lower than the norm; 128 (29.2%) recipients were classified as having poor sleep quality (global PSQI > 7). In the component score of PSQI, sleep onset latency was the highest; the others from high to low are sleep disturbance, daytime dysfunction, subjective sleep quality, sleep efficiency, sleep duration, and use of hypnotic medication. A total of 19.6% reported sleeping fewer than 6 hours a night, 64.8% reported that they had to get up to use the bathroom, and 50.0% woke up in the middle of the night or early morning at least 1 night per week in the past month. Significant differences in the PSQI scores were observed in renal transplant patients of different sex, age, residence, career, length of post-renal transplant period, comorbidity, kidney function, and depressive symptoms (P < .05). The PSQI scores were positively correlated with depression (Self-Rating Depression Scale) (P < .01) but negatively correlated with inquisitiveness (Three-Dimensional Inventory of Character Strengths-inquisitiveness) and psychological well-being (Flourishing Scale) (P < .01). CONCLUSION The sleep quality of renal transplant patients was lower than that of the general population. Character strengths and well-being can increase the level of sleep quality in renal transplant patients. Psychosocial intervention is necessary for improving the sleep quality of renal transplant recipients in China.

Abstract
Tissue clearing technique enables visualization of opaque organs and tissues in 3-dimensions (3-D) by turning tissue transparent. Current tissue clearing methods are restricted by limited types of tissues that can be cleared with each individual protocol, which inevitably led to the presence of blind-spots within whole body or body parts imaging. Hard tissues including bones and teeth are still the most difficult organs to be cleared. In addition, loss of endogenous fluorescence remains a major concern for solvent-based clearing methods. Here, we developed a polyethylene glycol (PEG)-associated solvent system (PEGASOS), which rendered nearly all types of tissues transparent and preserved endogenous fluorescence. Bones and teeth could be turned nearly invisible after clearing. The PEGASOS method turned the whole adult mouse body transparent and we were able to image an adult mouse head composed of bones, teeth, brain, muscles, and other tissues with no blind areas. Hard tissue transparency enabled us to reconstruct intact mandible, teeth, femur, or knee joint in 3-D. In addition, we managed to image intact mouse brain at sub-cellular resolution and to trace individual neurons and axons over a long distance. We also visualized dorsal root ganglions directly through vertebrae. Finally, we revealed the distribution pattern of neural network in 3-D within the marrow space of long bone. These results suggest that the PEGASOS method is a useful tool for general biomedical research.
