O traumatismo dentário é considerado um problema de saúde pública devido a sua alta prevalência, podendo acometer a boca, os tecidos de suporte e/ou tecidos duros do dente. Em algumas situações, esse dente traumatizado terá sua condição pulpar comprometida, levando a necessidade do tratamento endodôntico. O objetivo do presente estudo foi avaliar as implicações endodônticas de dentes com histórico de trauma dentário atendidos na Clínica Escola da Unidade de Ensino de Feira de Santana (UNEF). Trata-se de um estudo transversal quantitativo, onde foram as avaliados os prontuários dos pacientes que realizaram tratamento endodôntico na Clínica Escola entre 2019 e 2021, sendo selecionados para compor a pesquisa apenas os que realizaram o tratamento endodôntico como consequência do trauma na unidade. Esses pacientes foram avaliados clínica e radiograficamente. Dos 382 pacientes que realizaram o tratamento endodôntico na Clínica Escola, 21 sofreram trauma, desses 52% eram mulheres, entre 51-60 anos (29%) a principal causa foi a queda (33%), o dente mais acometido foi o incisivo central (57%), tendo como maiores consequências do traumatismo a fratura coronária (82%) e a necrose pulpar (52%). Com base nos resultados do presente estudo, é possível concluir que a necrose pulpar, associada a fratura dentária foram as principais implicações dos dentes tratados endodonticamente com histórico de trauma dentário atendidos na Clínica Escola da Unidade de Ensino Superior de Feira de Santana (UNEF), sendo imprescindível que esses pacientes permaneçam em acompanhamento clínico e radiográfico para avaliar as implicações tardias.

Published: June 2022

Background: Acute myocardial infarction (AMI) is often characterised pathologically as the death of cardiomyocytes as a consequence of persistent ischaemia result in an acute imbalance among oxygen supply and demand.
Coronary artery disease (CAD) is the leading cause of death worldwide. AMI mainly affects patients older than 40 years of age, however, young can suffer MI. In the developing countries, CAD is becoming an epidemic, where it occurs in younger persons at greater rates.
Clinical features and prognosis of young patients tend to vary from those of older individuals.
the outcomes of a MI may be especially severe at a young age because of its larger potential influence on the patient's psyche, capacity to work, and socioeconomic burden.
AMI is less prevalent in young people than in older persons, since only 2 to 6 % of the younger population suffers from the condition.
Primary PCI is the optimal therapy for STEMI if it can be done promptly, preferably within 90-120 minutes of provider contact.
Methods: The present research performed on 60 subjects who had AMI and treated with primary PCI. The cases were allocated into 2 groups, group 1 involved young subjects aged 40 years old or less (30 patients) and group 2 involved older patients aged more than 40 years (30 patients). All patients underwent complete history taking, cardiological clinical examination, investigations, coronary angiography and PCI.
Results: Concerning age there was statistically significant difference among two groups while there was no significant difference regarding to sex. regarding risk factors there was significant difference among both groups regarding to hypertension, DM, previous MI, cerebrovascular disease and drug abuse. Regarding to laboratory investigation, there was no significant difference regarding CK, CKMB, creatinine and random blood sugar. There was no significant difference regarding to culprit artery and TIMI flow after PCI while there was statistically significant difference regarding number of vessels involved. Regarding to outcome there was no significant variation among the two groups regarding to acute HF, cardiogenic shock, re-infarction, and death. As regarding to bleeding, it was significant higher in group II.
Conclusions: Prevalence of Acute ST Elevation Myocardial Infarction “STEMI” in young people is increasing due to sedentary and stressful lifestyle and bad habits as smoking and addiction. The most widespread and important risk factors in these patients are smoking, addiction, mental stress and hyperlipidemia with less prevalence of hypertension and diabetes mellitus. Young patients present most commonly with anterior then inferior STEMI.

Envidor is a new product in Norway containing the active substance spirodiclofen. The product is applied for use as an insecticide and acaricide in fruit, berries and ornamentals (field, glasshouses and tunnels). The Norwegian Scientific Committee for Food Safety (VKM) was asked by the Norwegian Food Safety Authority to perform a risk assessment on human health, environmental fate and ecotoxicological effects of the active substance and the product. The risk assessment of the product was finalized at a meeting November 25, 2010, by VKM’s Scientific Panel on plant protection products (Panel 2). VKM Panel 2’s conclusion is as follows:
Both Envidor and the active substance spirodiclofen showed low acute oral -, dermal - and inhalation toxicities in animal studies, but showed skin sensitising properties. The estimated risk for operators is assessed as minimal provided adequate use of personal protective equipment.
Spirodiclofen may have endocrine disrupting effects, but the in vivo data are not sufficient to make a firm conclusion at this point. Adrenals and other organs of the endocrine system, including the reproductive system, are target organs for chronic toxicity of spriodiclofen. Males seem to be more sensitive than females for adverse reproductive effects of spirodiclofen. Decreased testes and epididymides sizes, testes atrophy and decreased number of sperm were seen both in the parental and subsequent generation of rats. No teratogenic effect of spirodiclofen was seen.
The disturbances in the endocrine system may account for the carcinogenic potential of spirodiclofen as evidenced by tumours in testicles, uterus and liver of animals. Spirodiclofen is not considered genotoxic. The Panel regards spirodiclofen to be carcinogenic and toxic to the reproduction in laboratory animals.
Both spirodiclofen and its metabolites are rapidly degraded in soil, but while spirodiclofen has a low mobility due to high soil sorption, its metabolites are highly mobile.
Use of Envidor with the proposed application regime implies a very high risk for adverse effects on bees and non-target arthropods due to exposure to the active substance spirodiclofen. The risk for adverse effects of spirodiclofen on other terrestrial organisms, and on aquatic organisms provided that a buffer zone of 30 m to surface water is applied, is considered to be minimal.

AbstractHighly volatile solid additives have attracted much attention recently because they enhance molecular packing order and possibly solve the problems of poor reproducibility and instability of polymer solar cells (PSCs) with solvent additives. The shortcoming is that existing solid additives require thermal annealing (TA) to remove them from the active layer, leading to an increase in the complexity of the device fabrication process and morphology rearrangement problems. This study introduces a commercially available, low‐cost, and highly volatile material, naphthalene (NA), as a solid additive used in PSCs based on PM6: Y6. NA is well mixed with a non‐fullerene acceptor and can restrict excessive aggregation of the donor and acceptor, producing efficiencies comparable to PSCs processed by 1‐chloronaphthalene (CN) solvent additive. As a result, a maximum power conversion efficiency (PCE) of 16.52% for NA‐processed PSC is achieved, higher than that of a PCE of 16.07% for CN‐processed PSC with TA. NA‐processed PSCs exhibit comparable efficiencies (PCE of 16.10%) without TA treatment and higher reproducibility/stability than CN‐processed PSCs. This study demonstrates a low‐cost and excellent volatile solid additive to improve the device performance and the potential for exploring new solid additives that can readily be made volatile without TA.

Published: June 2022

AbstractMultiplexing technology with increased information capacity plays a crucial role in the realm of acoustic communication. Different quantities of sound waves, including time, frequency, amplitude, phase, and orbital angular momentum (OAM), have been independently introduced as the physical multiplexing approach to allow for enhanced communication densities. An acoustic metasurface is decorated with carbon nanotube patches, which when electrically pumped and set to rotate, functions as a hybrid mode‐frequency‐division multiplexer with synthetic dimensions. Based on this spatiotemporal modulation, a superposition of vortex beams with orthogonal OAMs and symmetric harmonics are both numerically and experimentally demonstrated. Also, flexible combinations of OAM modes with diverse frequency shifts are obtained by transforming the azimuthal phase distributions, which inspires a mode‐frequency‐division multiplexing approach that significantly promotes the communication capacity.

AbstractLight interaction physical properties of MXenes are fundamentally important and promising for developing new broadband photodetection applications. In this work, the significant influence of intercalants on the photo‐electronic properties of MXenes is studied. It is found that the intercalated H2O‐induced inter‐flake resistance greatly restricts the photon excitation responsivity of Ti3C2Tx, resulting in a slow and irreversible resistance change under laser irradiation. After deintercalation of H2O by in situ laser writing, the resistance of Ti3C2Tx responds fast and reversibly to laser excitation and the variation range is proportional to laser power. By extending the findings to another MXene member, Mo2TiC2, the intercalant induced resistance is successfully developed for optoelectronic detection. By selectively deintercalating H2O in the as‐prepared Mo2TiC2 which is co‐intercalated by H2O and TMAOH, bare TMAOH intercalated Mo2TiC2 shows fast and reversible resistance changes with laser. Moreover, the resistance of bare TMAOH intercalated Mo2TiC2 shows a negative temperature coefficient behavior while the fully deintercalated Ti3C2Tx shows a positive temperature behavior. These findings elucidate the understanding of the optoelectronic properties of MXenes and provide insights into the engineering of interfacial chemistry of MXenes for performance enhancement toward various detectors/sensors beyond optoelectronic applications.

AbstractOrganic upconversion devices (OUCs) consist of an organic infrared photodetector and an organic visible light‐emitting diode (OLED), connected in series. OUCs convert photons from the infrared to the visible and are of use in applications such as process control or imaging. Many applications require a fast OUC response speed, namely the ability to accurately detect in the visible a rapidly changing infrared signal. Here, high image‐contrast, narrowband OUCs are reported that convert near‐infrared (NIR) light at 980 and 976 nm with a full‐width at half maximum of 130 nm into visible light. Transient photocurrent measurements show that the response speed decreases when lowering the NIR light intensity. This is contrary to conventional organic photodetectors that show the opposite speed‐versus‐light trend. It is further found that the response speed increases (when using a phosphorescent OLED) or decreases (for a fluorescent OLED) when increasing the driving voltage. To understand these surprising results, an analysis by numerical simulation is conducted. Results show that the response speed behavior is primarily determined by the electron mobility in the OLED. It is proposed that the low electron drift velocity in the emitter layer sets a fundamental limit to the response speed of OUCs.

Published: June 2022

AbstractLithium‐sulfur (Li–S) batteries are promising as next‐generation energy storage systems. Adsorbents for sulfide species are favorably applied to the cathode, but this substrate often results in a surface‐passivating lithium sulfide(Li2S) film with a strong adsorption of Li2S. Here, an amorphous titanium suboxide (a‐TiOx) is presented that strongly adsorbs lithium polysulfides (Li2Sx, x < 6) but relatively weakly adsorbs to Li2S. With these characteristics, the a‐TiOx achieves high conversion of Li2Sx and high sulfur utilization accompanying the growth of particulate Li2S. The DFT calculations present a mechanism for particulate growth driven by the promoted diffusion and favorable clustering of Li2S. The a‐TiOx‐coated carbon nanotube‐assembled film (CNTF) cathode substrate cell achieves a high discharge capacity equivalent to 90% sulfur utilization at 0.2 C. The cell also delivers a high capacity of 850 mAh g–1 even at the ultra‐high‐speed of 10 C and also exhibits high stability of capacity loss of 0.0226% per cycle up to 500 cycles. The a‐TiOx/CNTF is stacked to achieve a high loading of 7.5 mg S cm–2, achieving a practical areal capacity of 10.1 mAh cm–2.

AbstractWith rapid development of radar and infrared (IR) surveillance technologies, the need for microwave‐IR compatible camouflage is now more than ever. Here, a novel multispectral metadevice is proposed to simultaneously achieve microwave scattering reduction, dynamic IR camouflage, and low IR reflection. This metadevice is constructed by the coding thermoelectric elements with the properly designed phase arrangement, and the incident microwave energy can be redirected to the nonthreatening directions for specular reflection reduction. The dynamic IR camouflage with low IR reflection is realized by using the thermoelectric cooling and heating effect and high‐IR‐absorptivity surface. The above three functionalities are demonstrated by experimental measurement. The 10 dB scattering reduction can be realized at the microwave band of 10–16.1 GHz. In the IR region, the designed metadevice can not only dynamically modulate the surface temperature for matching different background temperatures, but also realize the pixel temperature control for adapting to a spatially varying thermal background. In addition, it reflects almost no surrounding thermal signals compared with the traditional low‐emissivity IR stealth material. This study paves an effective way to achieve microwave‐IR compatible camouflage, which may inspire the future researches and applications in multispectral camouflage and stealth fields.
