Because ALEXIS is a spinning satellite, it is an ideal platform with which to study the time variability of the EUV cosmos. The main thrusts of this effort are to 1) detect EUV sources at known and unknown locations, 2) provide notification of transients in near real time to enable immediate follow-up from other observatories, and 3) create a time history of observed sources for comparison with previously published catalogs to aid in determining long duration variability from EUV sources.

Abstract Background:COVID-19, caused by SARS-CoV-2 has become the most threatening issue to all populations around the world. It is directly and indirectly affecting all of us and thus, is a emergence topic dealt in global health. In order to avoid the infection, various studies have been done and still ongoing. Now having over 141 million cases of COVID19 and causing over 3 million deaths around the world, the tendency of infection and degree severity of the disease shown in different groups of people came up as an issue. Here, we reviewed 21 papers on SNPs related to SARS-CoV-2 infection severity and analyzed the results of them.Methods:The PubMed databases were searched for papers discussing SNPs associated with SARS-CoV-2 infection severity. Clinical studies with human patients and statistically showing relevance of the SNP with virus infection were included. Quality Assessment of all papers were done with Newcastle Ottawa Scale.Results:In the analysis, 21 full-text literatures out of 2956 screened titles and abstracts, including 63496 cases, were included. All were human based clinical studies, some based on certain regions gathered patient data and some based on big databases obtained online. ACE2, TMPRSS2, IFITM3 are the genes mentioned most frequently that are related with SARS-CoV-2 infection. 20 out of 21 studies mentioned one of more of those genes. The relevant genes according to SNPs were also analyzed. rs12252-C, rs143936283, rs2285666, rs41303171, and rs35803318 are the SNPs that were mentioned at least twice in two different studies.Conclusions: We found that ACE2, TMPRSS2, IFITM3 are the major genes that are involved in SARS-CoV-2 infection. The mentioned SNPs were all related to one or more of the above mentioned genes. There were discussions on certain SNPs that increased the infection severity to certain ethinic groups more than the others. However, as there is limited follow up and data due to shortage of time history of the disease, studies may be limited.

Background: Epidemiology studies suggest that high magnesium intake may decrease the risk of stroke by reducing hypertension, endothelial dysfunction and carotid artery thickness, but the results are inconsistent. We therefore examined the association between magnesium intake and stroke type in a cohort with repeated measurement of diet, long duration of follow up, and a large sample size. Methods: We prospectively followed 86,149 women in the Nurses’ Health Study, aged 35 to 55 years, who were free of diagnosed cardiovascular disease and cancer at baseline in 1980. Data on dietary intake were collected with a semi-quantitative food frequency questionnaire at baseline in 1980, 1984, 1986 and then every 4 years, while data on stroke, stroke risk factors and potential confounders were collected at baseline and updated biennially. Strokes were classified according to the National Survey of Stroke criteria; and strokes for which medical records were not available were classified as probable/unknown. We calculated the hazard ratio (95% CI) of stroke by quintiles of magnesium intake, using multivariate Cox proportional hazard models, adjusting for potential confounders. Results: During 28 years of follow-up, 3237 total strokes (1664 ischemic, 544 hemorrhagic and 1029 probable/unknown) were documented. In multivariate analyses adjusting for age, total calories, smoking, body-mass index, parental history of heart disease, alcohol intake, physical activity, menopausal therapy, history of hypertension, hypercholesterolemia and diabetes at baseline, as well as use of multivitamin, aspirin, and thiazides, women in the highest quintile of magnesium intake had a relative risk (RR) of 0.85 (95% CI, 0.72 to 0.96; P for trend=0.03) for total stroke; 0.86 (95% CI, 0.72 to 1.01; P for trend=0.05) for ischemic stroke; and 0.85 (95% CI, 0.62 to 1.08; P for trend=0.37) for hemorrhagic stroke, compared with those in the lowest quintile. Further adjustment for potassium and calcium attenuated these associations; for total stroke the risk estimate was 0.90 (0.75 to 1.06; P for trend=0.38). Conclusions: Low magnesium intake may contribute to higher risk of stroke, but distinction from potential effects of potassium and calcium is difficult.

The number of elderly people worldwide is rigidly increasing due to decrease in birth rates and innovations implemented in medical field. Due to the increase in elderly people population diseases like dementia are also being increased year by year. Having done many kinds of research it is found that there is no permanent treatment for diseases like dementia, even if those patients come in public they look similar to normal people, however, people with dementia have abnormal behaviors like loss of patience, aggression, lack of thinking which in turn causes burden to family members and caretakers. In order to address this issues, this paper demonstrates a follow-up and rescue program for the elderly. The system includes a GPS receiver, a GSM module and a long-distance RF transmitter and receiver, real-time location. Families and care takers can obtain real-time information and history of patient location through GPS to avoid loss of elderly patients. With the help of this system, the number of losing patients will be decreased and the pressure on the caretakers and family people will be cut down to some extent.

Chewing betel nut is common in Taiwan. Although previous studies have shown that chewing betel nuts is associated with adverse health effects, findings about the impact on bone density have been inconsistent. Therefore, the aim of this study was to investigate the correlation between betel nut chewing and calcaneus ultrasound T-score in a longitudinal study of 118,856 participants from the Taiwan Biobank. Of these participants, 27,002 were followed up with for a median of 4 years. The T-score of the calcaneus was measured in the non-dominant foot using ultrasound. Multivariable analysis showed that a history of chewing betel nut (coefficient β = −0.232; p < 0.001) was significantly associated with low baseline T-score in all participants (n = 118,856). In addition, a long duration of betel nut chewing (per 1 year; coefficient β = −0.003; p = 0.022) was significantly associated with a low baseline T-score in the participants with a history of chewing betel nut (n = 7210). Further, a long duration of betel nut chewing (per 1 year; coefficient β = −0.004; p = 0.039) was significantly associated with a low ΔT-score in the participants with a history of chewing betel nut (n = 1778) after 4 years of follow-up. In conclusion, our results showed that betel nut chewing was associated with a decrease in calcaneus ultrasound T-score, and thus, it is important to stop chewing betel nut to help prevent an increased risk of osteoporosis in the Taiwanese population.

Abstract Background COVID-19, caused by SARS-CoV-2 has become the most threatening issue to all populations around the world. It is, directly and indirectly, affecting all of us and thus, is an emerging topic dealt in global health. To avoid the infection, various studies have been done and are still ongoing. COVID-19 cases are reported all over the globe, and among the millions of cases, genetic similarity may be seen. The genetical common features seen within confirmed cases may help outline the tendency of infection and degree severity of the disease. Here, we reviewed multiple papers on SNPs related to SARS-CoV-2 infection and analyzed their results. Methods The PubMed databases were searched for papers discussing SNPs associated with SARS-CoV-2 infection and severity. Clinical studies with human patients and statistically showing the relevance of the SNP with virus infection were included. Quality Assessment of all papers was done with Newcastle Ottawa Scale.

There were discussions on certain SNPs that increased the infection and severity to certain groups more than the others. However, as there is limited follow-up and data due to a shortage of time history of the disease, studies may be limited.

AbstractThe wind power industry is highly sensitive to weather, and there is a clear impact on turbine efficiency associated with icing, which can cause significant power losses and even result in the total shutdown of wind farms. Therefore, accurate analyses and forecasts of wind- and icing-related meteorological variables are of great importance. To this end, the Local Analysis and Prediction System (LAPS)–LOWICE system has been developed to produce real-time, hourly estimates of the presence, intensity, and impacts of icing on wind power production. As part of this development, it became clear that power losses did not correlate well with measured icing loads but correlated reasonably well with the time history of icing rate in combination with ice loss due to melting, sublimation, and shedding.

Background: Although foam sclerotherapy of varicose tributaries is common in daily practice, scientific evidence for the optimal sclerosant-concentration and session-frequency is still low. This study aimed to increase the knowledge on foam sclerotherapy of varicose tributaries and to evaluate the efficacy and safety of foam sclerotherapy with 0.5 % polidocanol in tributaries with 3-6 mm in diameter. Patients and methods: Analysis of 110 legs in 76 patients. Injections were given every second or third day. A maximum of 1 injection / leg and a volume of 2ml / injection were administered per session. Controls were performed approximately 6 months and 12 months after the start of therapy. Results: 110 legs (CEAP C2-C4) were followed up for a period of 14.2 ± 4.2 months. Reflux was eliminated after 3.4 ± 2.7 injections per leg. Insufficient tributaries were detected in 23.2 % after 6.2 ± 0.9 months and in 48.2 % after 14.2 ± 4.2 months, respectively. Only 30.9 % (34 / 110) of the legs required additional therapy. In 6.4 % vein surgery was performed, in 24.5 % similar sclerotherapy was repeated. Significantly fewer sclerotherapy-sessions were required compared to the initial treatment (mean: 2.3 ± 1.4, p = 0.0054). During the whole study period thrombophlebitis (8.2 %), hyperpigmentation (14.5 %), induration in the treated region (9.1 %), pain in the treated leg (7.3 %) and migraine (0.9 %) occurred. One patient with a history of thrombosis developed thrombosis of a muscle vein (0.9 %). After one year there were just hyperpigmentation (8.2 %) and induration (1.8 %) left. No severe adverse effect occurred. Conclusions: Foam sclerotherapy with injections of 0.5 % polidocanol every 2nd or 3rd day, is a safe procedure for varicose tributaries. The evaluation of efficacy is difficult, as it can hardly be said whether the detected tributaries in the controls are recurrent veins or have recently developed in the follow-up period. The low number of retreated legs indicates a high efficacy and satisfaction of the patients.
