I wish to draw attention to the rising influence of short video content on social media and its potential negative impacts on adult health, particularly its contribution to conditions such as hypertension.

Introduction: Number of obese people is growing on a daily basis in Brazil, including morbid obese ones, but there is still a lack of studies with this subject. Due to this, the main goal of this study was to identify body profile, physiological variables behavior and oxygen consumption in grade III obese women, submitted to an ergospirometric test in arm ergometer. Method: Take part in this study, thirteen (13) female grade III obese patients between 20 and 40 years. They were submitted to an electric bioimpedance test for body composition measurement and an Ergospirometric test in arm ergometer for oxygen consumption, heart rate, and oxygen saturation, systolic and diastolic arterial pressure, resting and after exercises, analysis. Results: The patients revealed a BMI of 46.5±3.81 kg/m², 51.9±1.59% of body fat percentage. The patients reached 168.2±4.57bpm of heart rate, didn’t make any hypertensive response to the effort reaching an arterial pressure of 171.1±22.15mmHg x 87.5±4.18mmHg. Oxygen saturation was 98±0.71% and oxygen consumption peak was, also in average, 12.3±2.75ml.kg.min-1. Conclusion: It was verified that there was no oxygen saturation drop nor hypertensive response and all of the patients reached the maximum heart rate. 

Graphical abstract Biodegradation of implanted gold in human tissue. TEM images reveal markedly biodegradation of implanted gold and re-crystallization of dissolved gold as nanoparticle of different size, shape and crystallinity. Highly crystalline icosahedral Au nanoparticle and the corresponding power spectrum are shown on top. Background: Despite the importance of biodegradation for the durability of metal prosthesis and the widely use of gold implants, there exist a lack of knowledge regarding the stability of pure gold in tissue. Methods: We studied biodegradation of grids of pure gold, nickel, and copper as well as middle ear prosthesis of gold, platinum or titanium. Metals were implanted into rat skin and humans. Dissolution and re-crystallization process of the metals was analysed using SEM, TEM, power spectra as well as elemental analysis by EDX and EELS/ESI. Results: Biodegradation of gold was detected, presumably by solving and re-precipitation of gold around implants. Gold cluster, nanoparticles, and mesostructures were detected, formed by dissolution and re-crystallization process. This process results into a migration of gold into the farer off tissue. Cellular filaments as biomolecular templates facilitate the formation of mesostructures. Loss of function of middle ear prosthesis by biodegradation is caused by chronic inflammation and fibrosis. Indeed, similar processes were detected with platinum, but in a very lower level. Conclusion: Noble metal implants undergo biodegradation in oxidative environment in tissue. The dissolution – recrystallization process can be explained by enzyme catalysed redox processes comprising reactive oxygen species and reduction agents as ascorbic acid present in cells and body tissue. Enymes like myeloperoxidase inside lysosomes of inflammatory cells produce hypochloride ions and H2O2 which can dissolve the gold. General significance: The crucial role of the specific chemical environments of gold implants in tissue for their chemical stability and durability of function has been demonstrated. Due to widely use and importance of gold implants, this finding is of general interes.

Heftiness, a mind boggling interchange among ecological and hereditary factors and is related with critical horribleness and mortality. Utilization of herbs for the administration of heftiness in the ongoing occasions is pulling in consideration. A web and manual based writing overview was led to survey the measure of data accessible on the natural items for weight administration. Customary writing, PubMed, Scopus, Google researcher databases were screened up to February 2012. The pursuit words were “stoutness”, “home grown medication/items/separates”, “restorative plants”, “customary drug”, “Ayurvedic prescription” without narrowing/constraining looking words or components. Distributions just with edited compositions/full articles and books were inspected in the pursuit. In light of the accessible writing, for huge numbers of the natural and weight reduction items, there is minimal distributed data and there have been no clinical preliminaries or the level of proof is restricted. Our writing study additionally demonstrated that these home grown items fall under an adequate level of proof or with no scientific foundation by any stretch of the imagination, or they have a logical discerning however not to an acknowledgment level. Endeavors were made in the audit to characterize the highlights of conceivable natural weight reduction item. A perfect home grown enemy of stoutness item ought to diminish the weight by 10% over fake treatment of treatment by demonstrating a proof of change of bio markers like blood pres-beyond any doubt, lipids and glycemia with no reactions.

Ra-223 dichloride is a first-in-class alpha-emitting radiopharmaceutical recently introduced into clinical practice for treatment of men with Castration-Resistant Prostate Cancer (CRPC) and symptomatic bone metastases. Due to the proven benefit on Overall Survival and the favorable toxicity profile, Ra-223 therapy is gaining widespread use in both US and Europe. In this article, we describe the routinary management of patients undergoing Ra-223 treatment in our Institution. Currently, Ra-223 therapy is indicated for 6 intravenous injections (55 kBq per kg of body weight) administered every 28 days. In comparison to other radiopharmaceuticals, Ra-223 handling and administration do not need any additional training for authorized users. Due to the minimal external dose rate emission, Ra-223 dichloride can be delivered in an outpatient setting. Moreover, no particular precautions other than standard hygiene measures must be taken by patients’ family members or caregivers. Ra-223 therapy is associated to a favorable hematologic toxicity profile, while non-hematologic adverse events are generally mild and easy to manage. Given the favorable toxicity profile of this treatment, clinical trials are currently ongoing to evaluate efficacy and safety of Ra-223 treatment in combination or sequence with recently approved drugs such as abiraterone acetate, enzalutamide and sipuleucel-T. In addition, the recent interest in Ra-223 bone lesion dosimetry could open the way to a dosimetric-based therapeutic approach with Ra-223. In this new scenario, results of these promising clinical trials may help clarifying the optimal sequencing of new therapeutic possibilities for metastatic CRPC and the appropriate eligibility criteria for Ra-223 treatment in oncologic patients.

The Uranium extraction and processing plant of INB (Brazilian Nuclear Industries) is in Caetité, a city located in a region hosting the largest Uranium reserve of the country. The degree of Uranium contamination in the Caetité population was investigated before using teeth as bioindicator, where a quite high Uranium concentration was measured in this region, about 160 times higher than the world-wide average. Radiobiological risks are here evaluated from Uranium burdens in organs as skeleton, kidneys, liver, tissues and blood, which were estimated from transfer coefficients and effective internal doses. This was accomplished by means of calculations with the use of the STATFLUX/ICRP approach, plus a set of Uranium transfer rate parameters as function of individual’s age assuming an uninterrupted exposure over a period of 60 years. It was found that U ingestion rates by residents of Caetité are three orders of magnitude higher than worldwide average, indicating that food and water would exhibit high levels of contamination. Calculated effective internal doses range from a minimum of one to a maximum of three orders of magnitude higher than background doses, for blood and bones respectively. The likelihood that this circumstance could lead to serious health problems as e.g. neoplasia is addressed. The methodology presented in this work offers subsidies for further studies on environmental pollution by radionuclides.

The forensic identification of nitrate ions in post-blast pit soil samples is crucial for investigating nitrate-based explosive incidents owing to environmental factors such as rainfall and monsoon conditions, which can significantly alter the concentration and distribution of nitrate residues at blast sites, as nitrate ions are completely soluble in water. This study investigated the influence of rainfall on the retention and detectability of nitrate ions in pit soil collected from spiked simulated explosive samples, replicating the topographical conditions of hilly regions frequently impacted by insurgent and terrorist activities. Ion Chromatography (IC), a highly sensitive and selective analytical technique, was employed to quantify nitrate ion concentrations within the soil matrix. This study aimed to elucidate the mobility, leaching behavior, and retention of nitrate ions in soils affected by blast under natural drizzling rainfall conditions.

Background: AngioJetTM rheolytic thrombectomy has been used in the treatment of deep vein thrombosis (DVT) to prevent post-thrombotic syndrome. Though not widely appreciated, it has the potential to cause intravascular haemolysis. Report: A 37 year old man with no previous medical history presented to his GP with a three week history of progressive right upper limb swelling. Doppler imaging confirmed right upper limb DVT and CT scan demonstrated thoracic outlet syndrome. The patient underwent AngioJetTM thrombectomy followed by IV heparin infusion. Successful revascularisation of the occluded vein was achieved. Overnight he developed haematuria, which was initially attributed to IV heparin. Urinalysis however revealed no red cells or casts. Apart from an Hb drop from 134 to 117 his blood profile and blood film showed no abnormality. He subsequently developed progressive oliguria with marked oedema and acute kidney injury (AKI). His creatinine peaked at 1070umol/l at 96 hours post procedure and he was started on intermittent dialysis. He remained dialysis dependent for 6 days. Ultrasound imaging excluded urinary obstruction. Autoimmune and vasculitic serology were negative. Intravascular haemolysis and haemoglobinuria was confirmed by raised LDH (1714u/L) and low haptoglobin (<0.1units). Direct Coomb’s test, Cold agglutinin test and paroxysmal nocturnal haemoglobinuria screen were negative. The patient’s renal function normalised over 3 months. Conclusions: The likely cause of this man’s AKI is heme pigment nephropathy from intra-vascular haemolysis. Increased awareness of this condition may allow early identification and intervention to reduce the risk of renal injury from AngioJetTM associated haemolysis.

In the beginning of 1973 in the USSR the study of possibility of LJE designing was conducted. The reflector, located in the tail of the rocket prototype, concentrated the obtained radiation in air and ensured micro-burst that the reactive thrust was created. The successful results of different models of the reflectors tests, which were at the same time the laser light receivers, had been obtained. One should note that all experiments pointed out above were conducted with the use of electric discharge CO2- lasers with power up to 10 kW, while for the injection into orbit of different highly and technologically effective equipment (global network connections, Internet, photo-monitoring of Earth surface, debris cleaning) the radiated power substantially higher is required. Thus, for example, for SC launching with the weight 1000 kg the laser with power not less than 15 MW is necessary [1,2].
