HDG increased key tricarboxylic acid (TCA) cycle metabolites, and decreased phosphoenolpyruvate and acetoacetate (P less then 0.05) suggesting that elevated levels of GLP-1 promote glycolysis and suppress GNG and ketogenesis, which collectively increase glucose clearance. These GLP-1-mediated effects on cellular metabolism help to explain why plasma GLP-1 concentrations decrease naturally in fasting pups as an evolved mechanism to help conserve glucose during the late-fasting period.Recent evidence indicates a crucial role for G protein-coupled estrogen receptor 1 (GPER1) in the maintenance of cardiovascular and kidney health in females. The current study tested whether GPER1 activation ameliorates hypertension and kidney damage in female Dahl salt-sensitive (SS) rats fed a high-salt (HS) diet. Adult female rats were implanted with telemetry transmitters for monitoring blood pressure and osmotic minipumps releasing G1 (selective GPER1 agonist, 400 μg/kg/day ip) or vehicle. Two weeks after pump implantation, rats were shifted from a normal-salt (NS) diet (0.4% NaCl) to a matched HS diet (4.0% NaCl) for 2 wk. Twenty-four hour urine samples were collected during both diet periods and urinary markers of kidney injury were assessed. Histological assessment of kidney injury was conducted after the 2-wk HS diet period. Compared with values during the NS diet, 24-h mean arterial pressure markedly increased in response to HS, reaching similar values in vehicle-treated and G1-treated rats. HS also significantly increased urinary excretion of protein, albumin, nephrin (podocyte damage marker), and KIM-1 (proximal tubule injury marker) in vehicle-treated rats. Importantly, G1 treatment prevented the HS-induced proteinuria, albuminuria, and increase in KIM-1 excretion but not nephrinuria. Histological analysis revealed that HS-induced glomerular damage did not differ between groups. However, G1 treatment preserved proximal tubule brush-border integrity in HS-fed rats. Collectively, our data suggest that GPER1 activation protects against HS-induced proteinuria and albuminuria in female Dahl SS rats by preserving proximal tubule brush-border integrity in a blood pressure-independent manner.Most of the energy consumed worldwide comes from non-renewable sources, such as oil derivatives, making it necessary to search for renewable, clean energy sources, with emphasis on biomass from agricultural and industrial waste. Coconut shell pellets (CSPs) and cashew nut shell pellets (CNSPs) were manufactured and subsequently subjected to chemical, thermal and exhaust gas analyses of their combustion. Mean temperature results in the combustion area were 366.44 ± 84.79°C (CSPs) and 295.00 ± 89.47°C (CNSPs). The exhaust gas combustion values were 19.43 ± 0.57% (CSPs) and 18.75 ± 0.77% (CNSPs) of O2, 2348 ± 1241 ppm (CSPs) and 2901 ± 499 ppm (CNSPs) of CO, 14.92 ± 5.06 ppm (CSPs) and 39.83 ± 10.91 ppm (CNSPs) of NOx, and 441.25 ± 130.41 ppm (CSPs) and 2841.50 ± 765.26 ppm (CNSPs) of CH4. In conclusion, the combustion process of CSPs proved to be less polluting and more energy efficient when compared with CNSPs. The analyses of the exhaust gases from the combustion of these biomasses can serve as a basis for the creation of safety parameters and public policies to regulate the use of biomass for energy purposes.
In high-income countries, the management of stroke has changed substantially over the years with the advent of thrombolysis and endovascular treatment. However, in low-income countries, such interventions may not be available, or patients may come to the hospital outside the time window no longer qualified for this therapy. Most studies on stroke units were conducted in high-income countries. Unfortunately, there has been no local multicenter data with large patient numbers showing the effectiveness of stroke units in the Southeast Asian region.
To compare the outcomes of patients allocated to stroke units (based on accepted criteria) to those allocated to general neurology wards in the Philippines.
This is an open, prospective, parallel, observational comparative study of patients from 11 institutions in the Philippines. Patients were allocated either to the stroke unit or to the general neurology ward by the admitting physician based on the criteria suggested by the Stroke Trialist Collaboration Groupeneral neurology wards.
Patients specifically admitted to stroke units in the Philippines based on established criteria have better outcomes than those admitted to general neurology wards.Osteogenesis imperfecta is characterised by low bone mineral density, bone fragility, fractures and deformity. We present five such children treated with intravenous pamidronate, which resulted in a decrease of fracture rate and increase in spinal bone mineral density.Feeding jejunostomy is a simple and common procedure done for providing enteral nutrition. Though generally safe, complications like dislodgement, clogging and leaking are commonly reported with an incidence as high as 44%. Intussusception is however a much rarer complication which may have catastrophic results and often needs urgent surgical intervention. We describe a case of a patient who underwent robot-assisted minimal invasive oesophagectomy but developed an intestinal obstruction in the follow-up period.Evidence-based decision-making is less common in low- and middle-income countries where the research capacity remains low. Nepal, a lower-middle-income country in Asia, is not an exception. We conducted a rapid review to identify the trend of health research in Nepal and found more than seven-fold increase in the number of published health-related articles between 2000 and 2018. The proportion of articles with Nepalese researchers as the first authors has also risen over the years, though they are still only in two-thirds of the articles in 2018.The SARS-CoV-2 pandemic has demonstrated both positive and negative effects on the environment. Major concerns over personal hygiene, mandated and ease in lockdown actions and slackening of some policy measures have led to a massive surge in the use of disposable personal protective equipment (PPE) and other single-use plastic items. This generated an enormous amount of plastic waste from both healthcare and household units, and will continue to do so for the foreseeable future. Apart from the healthcare workers, the general public have become accustomed to using PPE. These habits are threatening the land and marine environment with immense loads of plastic waste, due to improper disposal practices across the world, especially in developing nations. Contaminated PPE has already made its way to the oceans which will inevitably produce plastic particles alongside other pathogen-driven diseases. This study provided an estimation-based approach in quantifying the amount of contaminated plastic waste that can be expected daily from the massive usage of PPE (e.g. facemasks) because of the countrywide mandated regulations on PPE usage. The situation of Bangladesh has been analysed and projections revealed that a total of 3.4 billion pieces of single-use facemask, hand sanitizer bottles, hand gloves and disposable polyethylene bags will be produced monthly, which will give rise to 472.30 t of disposable plastic waste per day. The equations provided for the quantification of waste from used single-use plastic and PPE can be used for other countries for rough estimations. Then, the discussed recommendations will help concerned authorities and policy makers to design effective response plans. Sustainable plastic waste management for the current and post-pandemic period can be imagined and acted upon.As in many developing countries, municipal solid waste (MSW) management is one of the most significant challenges facing urban communities in Algeria. The effective management of solid waste involves the application of various treatment methods, and technologies to ensure the protection of public health and the environment. This research work aimed to examine potential production and utilization of refuse-derived fuel (RDF) from MSW to be used as a substitute fuel in cement kilns in Algeria. After receiving the input waste, sieves were used to categorize MSW according to size. The waste fractions >80 mm were subjected to a drying process in an open-air area and had been turned periodically in order to increase the dry matter (DM). A cost study was performed to evaluate the environmental and economic savings of RDF utilization in the cement industry. At the end of the drying process, as a consequence of the waste moisture reduction, the low heating value was found to be 16 MJ kg-1, and the DM 87%. Concerning heavy metal content, their concentrations were within the limits set by the European Committee for Standardization (CEN)/TC 343 standardization. The chlorine content was around 0.37% to 0.80%. The feasibility study of adding RDF as a substitute fuel in the cement industry showed that when 15% of RDF is used, the RDF consumption will be 4.7 metric tonnes (Mt) h-1, which will save 4347.2 Nm3 h-1 of natural gas and 0.3 Mt h-1 in carbon dioxide emissions, with a net gas cost saving of 65 USD h-1.The aims of this study were to analyze the results of inframalleolar bypass for chronic limb-threatening ischemia (CLTI) and to identify outcome-predicting factors. All consecutive patients undergoing inframalleolar bypass for CLTI between 2015 and 2018 were included in this retrospective, single-center study. TTNPB research buy Outflow artery was the most proximal patent vessel segment in continuity with inframalleolar arteries. Bypasses originating from the popliteal artery were defined as 'short bypasses'. Sixty patients underwent inframalleolar bypass, with four patients undergoing bilateral procedures, making a total of 64 limbs included. The mean age was 73 ± 14 and 52 (81%) were male. The great saphenous vein was the preferred conduit (n = 58, 91%), in a devalvulated fashion (n = 56, 88%). Superficial femoral artery was the most common inflow artery for 'long' grafts (n = 22, 34%), while popliteal artery was the inflow artery for all 'short' grafts (n = 25, 39%). Dorsalis pedis artery was chosen as an outflow artery in 41 patients (63%). Median follow-up was 21 months. Two-year primary and secondary patency, limb salvage, amputation-free survival, and overall survival rates were 67 ± 6%, 88 ± 4%, 84 ± 4%, 72 ± 6%, and 85 ± 4%, respectively. At multivariate analysis, dialysis was an independent predictor for poor primary patency (HR, 4.6; 95% CI, 1.62-13.05; p = 0.004), whereas a short bypass was independently associated with an increased primary patency (HR, 0.3; 95% CI, 0.10-0.89; p = 0.03). In conclusion, bypass grafting to the inframalleolar arteries resulted in good patency rates, limb salvage and overall survival. Dialysis patients had lower primary patency but still had good limb salvage and survival. Short bypass was a predictor of improved primary patency.The first case of COVID-19 was identified in Libya on 24/3/2020, and about 2 months later, the number of reported COVID-19 cases started to increase notably. The outbreak was first prominent in the southern region (Sabha) and then spread to the western and eastern parts of Libya. By 24/12/2020, the reported total number of deaths from COVID-19 reached 1415. There seems to be no published data on the size of the epidemic in Libya. Here, we estimated the number of Libyans exposed to COVID-19 by using a COVID-19 mortality adjusted mathematical model for the spread of infectious diseases. We estimated that 14-20% of the Libyan population have been exposed to the COVID-19 pandemic. Thus, the risk of spread of COVID-19 infections during the coming months is high, and a considerable number of Libyans, particularly the elderly and people with chronic diseases, should be protected against COVID-19 infection. This is particularly urgent in the light of unofficial reports that the relevant healthcare facilities are under extreme stress.
