Adult respiratory distress syndrome (ARDS) due to omeprazole-induced drug reaction with eosinophilia and systemic symptoms (DRESS): Case report and review of the literature.

Eosinophilia in not an uncommon findings in the intensive care unit (ICU); however, DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) syndrome, which is characterized by a hypersensitivity reaction to drugs and manifests as eosinophilia, systemic involvement and maculopapular erythematous rash 2-6 weeks after exposure to the offending drug, is an exceptional occurrence. We present the first case described in the literature of DRESS syndrome with pulmonary involvement in the form of interstitial pneumonitis and persistent adult respiratory distress syndrome (ARDS) secondary to proton pump inhibitors (PPI). The patient made a good recovery after withdrawal of the offending drug and long-term treatment with systemic corticosteroids. We also present a systematic review of all cases of DRESS with pulmonary involvement in the form of interstitial pneumonitis and cases of PPI-induced DRESS published to date; none of these describe pulmonary involvement.

Complications of Synthetic Midurethral Slings: Is There a Relevant Discrepancy Between Observational Data and Clinical Trials?

CONTEXT: The complications of synthetic midurethral slings (MUSs) in women with stress urinary incontinence (SUI) have become a globally debated issue. OBJECTIVE: To systematically review the short- and long-term complications of mesh slings reported in observational data compared with clinical trial data, to determine whether the complication rates from clinical trials reflects "real-world" observational data. EVIDENCE ACQUISITION: PubMed and Cochrane Library were searched. Methods as detailed in Preferred Reporting Items for Systematic Reviews and Meta-analyses and Cochrane Handbook for Systematic Reviews of Interventions were followed. EVIDENCE SYNTHESIS: Thirty registries/databases including 709 335 MUS procedures (1-22 yr of follow-up) were identified. MUS procedures were associated with intraoperative bladder perforation in 0.86-3.6%, urethral perforation in 0-0.1%, vascular injury in 0.04-0.1%, voiding lower urinary tract symptoms (LUTS) in 1.47-3.5%, vaginal exposure in 0.2-1.9%, and reoperation in up to 9% of cases. Forty-three randomised clinical trials were identified, including 6284 women who underwent MUS procedures and 2177 women who underwent other interventions (1-10 yr of follow-up). MUS procedures were associated with urinary tract perforation in 2.58%, vaginal injury in 1.43%, de novo voiding LUTS in 4.37%, de novo storage LUTS in 5.41%, mesh extrusion/exposure (vaginal/urinary tract) in 2.54%, dyspareunia in 2.26%, pain (pelvic/suprapubic/perineal) in 2.83%, and reoperation for complications required in 1.82% of cases. Meta-analyses of the randomised controlled trials revealed that retropubic MUSs were associated with more events of urinary tract perforation (risk ratio [RR] 9.81, 95% confidence interval [CI] 5.05-19.04, high certainty of evidence [COE]) and voiding LUTS (RR 1.57, 95% CI 1.19-2.07, high COE) than transobturator MUSs. MUSs were associated with more events of pain than mini-slings (RR 1.72, 95% CI 1.04-2.87, moderate COE). CONCLUSIONS: Short- and long-term data on complications of polypropylene mesh used for female SUI are fairly comparable when using outcome data from well-designed clinical trials or from less structured prospective or retrospective registries. Comparisons have to be made with caution since the two systems of data collection are inherently incomparable. This knowledge should be incorporated in the discussion on how to implement polypropylene mesh for female stress incontinence. PATIENT SUMMARY: In order to know whether mesh tapes used for treating stress incontinence work well and are safe, high-quality information is important. It appears that well-designed clinical studies give similar results to large registration databases. These data should be interpreted with caution in view of the different ways the information was collected. These results will help physicians and patients understand the risks of mesh tapes.

ß-hydroxybutyrate is a metabolic regulator of proteostasis in the aged and Alzheimer disease brain.

Loss of proteostasis is a hallmark of aging and Alzheimer disease (AD). Here, we identify ß-hydroxybutyrate (ßHB), a ketone body, as a regulator of protein solubility in the aging brain. ßHB is a small molecule metabolite which primarily provides an oxidative substrate for ATP during hypoglycemic conditions, and also regulates other cellular processes through covalent and noncovalent protein interactions. We demonstrate ßHB-induced protein insolubility across in vitro, ex vivo, and in vivo mouse systems. This activity is shared by select structurally similar metabolites, is not dependent on covalent protein modification, pH, or solute load, and is observable in mouse brain in vivo after delivery of a ketone ester. Furthermore, this phenotype is selective for pathological proteins such as amyloid-ß, and exogenous ßHB ameliorates pathology in nematode models of amyloid-ß aggregation toxicity. We have generated a comprehensive atlas of the ßHB-induced protein insolublome ex vivo and in vivo using mass spectrometry proteomics, and have identified common protein domains within ßHB target sequences. Finally, we show enrichment of neurodegeneration-related proteins among ßHB targets and the clearance of these targets from mouse brain, likely via ßHB-induced autophagy. Overall, these data indicate a new metabolically regulated mechanism of proteostasis relevant to aging and AD.

Ketogenic diet enhances the effects of oxycodone in mice.

Opioids have been used to manage pain for thousands of years, but they have significant potential for abuse. Prescription opioids, like oxycodone, are associated with 32% of overdoses, that have reached a total of 75,673 deaths in 2021. A major challenge is maximizing their therapeutic potential while minimizing the negative side effects including opioid use disorder (OUD). The Ketogenic Diet (KD) has been reported to reduce pain and decrease the severity of alcohol use disorder, yet its effects on oxycodone responses remain unknown. KD mice displayed increased oxycodone-induced locomotor activity and enhanced antinociceptive effects of oxycodone, suggesting a dietary effect on opiate sensitivity. Male KD mice exposed to chronic oxycodone exhibited increased naloxone-induced jumps, suggesting a sex-specific effect of diet on opioid withdrawal. Consistent with this, male KD mice self-administered less oxycodone while female KD mice did not differ from controls. Finally, no effect of KD on motivation to obtain oxycodone was observed during a progressive ratio schedule. These data suggest sex-biased effects of KD on responses to opioids that should be considered and potentially leveraged in both clinical pain management and treatment of OUD.

Photoswitching/back-switching assessment of biobased cellulose acetate/azobenzene handleable films under visible-light LED irradiation.

The light-induced processes performed by photofunctional polymer films are crucial aspects of developing integrated energy storage devices properly. Herein, we report the preparation, characterization, and study of the optical properties of a series of biobased cellulose acetate/azobenzene (CA/Az1) handleable films at different compositions. The photoswitching/back-switching behavior of the samples was investigated using varied LED irradiation sources. Additionally, poly(ethylene glycol) (PEG) was deposited onto cellulose acetate/azobenzene films to study the back-switching process's effect and nature in the fabricated films. Interestingly, the melting enthalpies of PEG before and after being irradiated with blue LED light were 2.5 mJ and 0.8 mJ, respectively. Conveniently, FTIR and UV-visible spectroscopy, thermogravimetry (TGA), contact angle, differential scanning calorimetry (DSC), polarized light microscopy (PLM), and atomic force microscopy (AFM) were used for the characterization of the sample films. Complementarily, theoretical electronic calculations provided a consistent approach to the energetic change in the dihedral angles and non-covalent interaction for the trans and cis isomer in the presence of cellulose acetate monomer. The results of this study revealed that CA/Az1 films are viable photoactive materials displaying handleability attributes with potential uses in harvesting, converting, and storing light energy.

Carcinoma escamoso híbrido de la planta del pie / Squamous hybrid carcinoma of the sole of the foot

Resumen El carcinoma escamoso (CEC) es un tumor maligno de la epidermis y sus anexos. Es el segundo en frecuencia después del carcinoma basocelular y presenta distintas variantes clinicopatológicas. El subtipo carcinoma verrucoso (CV) es una variante poco frecuente de CEC con características histopatológicas y comportamiento específico. Ocasionalmente, se pueden observar componentes carcinomatosos de células escamosas convencionales en el CV, denominándose a esta entidad tumores "híbridos", los cuales representan el 20% de los casos observados. Reportamos el caso de un paciente varón de 72 años con una gran lesión exofítica que compromete 5to dedo y planta de pie derecho con diagnóstico de carcinoma escamoso híbrido. El objetivo de la presentación es mostrar una asociación infrecuente, haciendo énfasis en su seguimiento cercano ya que puede manifestar cambios en su comportamiento clínico diseminándose a los ganglios linfáticos regionales.

Abstract Squamous carcinoma (SCC) is a malignant tumor of the epidermis and its appendages. It is the second most common after basal cell carcinoma and has different clinicopathological variants. The verrucous carcinoma (VC) subtype is a rare variant of SCC with histopathological characteristics and specific behavior. Occasionally, carcinomatous components of conventional squamous cells can be observed in the VC, this entity being called "hybridized" tumors, which represent 20% of cases.We report the case of a 72-year-old male with a large exophytic lesion involving the 5th right toe and foot with a diagnosis of squamous hybrid carcinoma. The objective of the presentation is to show an infrequent association, emphasizing its close follow-up as it can modify its clinical behavior by spreading to regional lymphnodes.

Indirect x-ray photodesorption of N215 and CO13 from mixed and layered ices.

X-ray photodesorption yields of N215 and CO13 are derived as a function of the incident photon energy near the N (∼400 eV) and O K-edge (∼500 eV) for pure N215 ice and mixed CO13:N215 ices. The photodesorption spectra from the mixed ices reveal an indirect desorption mechanism for which the desorption of N215 and CO13 is triggered by the photoabsorption of CO13 and N215, respectively. This mechanism is confirmed by the x-ray photodesorption of CO13 from a layered CO13/N215 ice irradiated at 401 eV on the N 1s → π* transition of N215. This latter experiment enables us to quantify the relevant depth involved in the indirect desorption process, which is found to be 30-40 monolayers in that case. This value is further related to the energy transport of Auger electrons emitted from the photoabsorbing N215 molecules that scatter toward the ice surface, inducing the desorption of CO13. The photodesorption yields corrected from the energy that can participate in the desorption process (expressed in molecules desorbed by eV deposited) do not depend on the photon energy; hence, they depend neither on the photoabsorbing molecule nor on its state after Auger decay. This demonstrates that x-ray induced electron stimulated desorption, mediated by Auger scattering, is the dominant process explaining the desorption of N215 and CO13 from the ices studied in this work.

Granuloma actínico: reporte de un caso / Actinic granuloma: a case report

Resumen El granuloma actínico es una dermatosis granulomatosa poco frecuente, que se observa en adultos de mediana edad con antecedentes de fotoexposición. Su patogénesis no es clara; siendo la teoría más aceptada la radiación solar como factor disparador. Se caracteriza por placas anulares con atrofia central y bordes eritematosos elevados que son similares a los observados en el granuloma anular. Se presenta el caso clínico de una paciente de 71 años, con placas anulares en antebrazos compatibles con granuloma actínico. Se comunica el caso por lo infrecuente de esta entidad y se realiza una revisión bibliográfica.

Abstract Actinic granuloma is a rare granulomatous dermatosis, seen in middle-aged adults with a history of photoexposure. Its pathogenesis is not clear; the most accepted theory being solar radiation as a triggering factor. It is characterized by annular plaques with central atrophy and raised erythematous borders that are similar to those seen in granuloma annulare. The clinical case of a 71-year-old patient with annular plaques on the forearms compatible with actinic granuloma is presented. The case is reported due to the infrequent nature of this entity and a bibliographical review is carried out.

Evaluación de los efectos de un dispositivo de entrenamiento de los músculos inspiratorios sobre la oxigenación muscular y la activación neuromuscular de los músculos respiratorios / [Evaluation of the effects of an inspiratory muscle training device on muscle oxygenation and neuromuscular activation of the respiratory muscles]

Objetivo: Comparar los cambios en la actividad electromiográfica y oxigenación muscular periférica de los músculos intercostales, en su condición de musculatura accesoria a la respiración, en pacientes con EPOC durante la realización de un test de marcha de 6 minutos (TM6M) con y sin el uso de un dispositivo FeelBreathe (FB).Material y métodos: Se seleccionaron a 20 sujetos diagnosticados de EPOC a los que se les realizaron dos TM6M separados al menos por 60 minutos. Aleatoriamente, cada uno de los pacientes realizó dos TM6M, uno usando el dispositivo FB y el otro sin FB (SFB) y se midieron durante la realización de ambos TM6M la actividad electromiográfica (EMG) obteniéndose la raíz de la media cuadrática (RMS), y por otro lado la oxigenación tisular de los músculos intercostales a través de la variable de oxihemoglobina (HbO2).Resultados: No hubo diferencias significativas en la distancia recorrida en ambos TM6M con FC a SFB. Tanto la RMS como la oxigenación tisular mostraron valores similares entre la condición FB vs. SFB al final de ambas pruebas (32,26 ± 101,94 μV vs 28,25 ± 87,02 μV; p = 0,16 y 70,63 ± 18,80 vs 70,74 ± 16,77; p = 0,975 respectivamente).Conclusiones: El estímulo de trabajo de la musculatura intercostal durante el TM6M con el dispositivo FB no compromete la aparición de la fatiga temprana por un exceso de activación o disminución de la oxigenación de dichos músculos al nivel de intensidad del TM6M. (AU)

Objective: To compare changes in electromyographic activity and peripheral muscle oxygenation of the intercostal muscles, in their condition as accessory muscles for respiration, in patients with COPD during a 6-minute walk test (6MWT) with and without the use of a FeelBreathe (FB) device.Material and methods: 20 subjects diagnosed with COPD who underwent two 6MTMs separated by at least 60 minutes were selected. Randomly, each of the patients underwent two 6MWT, one using the FB device and the other without FB (SFB) and electromyographic activity (EMG) was measured during the performance of both 6MWT, obtaining the root mean square (RMS), and on the other hand, tissue oxygenation of the intercostal muscles through the oxyhemoglobin (HbO2) variable.Results: There were no significant differences in the distance traveled in both 6MWT with HR to SFB. Both RMS and tissue oxygenation showed similar values between the FB condition vs. SFB at the end of both tests (32.26 ± 101.94 μV vs 28.25 ± 87.02 μV; p = 0.16 and 70.63 ± 18.80 vs 70.74 ± 16.77; p = 0.975 respectively).Conclusions: The work stimulus of the intercostal muscles during the 6MWT with the FB device does not compromise the appearance of early fatigue due to excessive activation or decreased oxygenation of these muscles at the intensity level of the 6MWT.

Clinical use of tissue plasminogen activator for systemic thrombolysis in dogs and cats.

INTRODUCTION: Systemic administration of tissue plasminogen activator (tPA) is seldomly reported in dogs and cats. ANIMALS: Client-owned animals receiving tPA (2010-2020). MATERIALS AND METHODS: Medical records of dogs and cats receiving tPA for distant known/suspected thrombus were reviewed. Fourteen dog visits (24 injections) and five cat visits (six injections) were included. RESULTS: Canine known/suspected thrombus included pulmonary thromboembolism (n=6), intracardiac thrombus (n=4), aortic thrombus (n=1), cranial vena cava thrombus (n=2), and femoral and iliac veins thrombus (n=1). Various canine primary diseases were represented, but open-heart surgery was the most common cause. Median time between diagnosis/suspicion of thrombus and tPA injection was 24.5 h (range, 3-150 h). Mean total tPA dose was 1.0±0.78 mg/kg. Clinical improvement occurred in 93% of dogs. Non-fatal complications were reported in 14% of dogs. Dogs' survival to discharge was 78.6% without identifiable non-survivor characteristics. Feline known/suspected thrombus included unilateral feline aortic thromboembolism (FATE) (n=2), bilateral FATE (n=2), and right renal artery thrombus. Feline primary diseases included cardiomyopathy (n=5). Median time between diagnosis/suspicion of thrombus and tPA injection was 4 h (range, 2-17 h) and median total tPA dose was 1.0 mg/kg (range, 0.6-1.4 mg/kg).Clinical improvement occurred during 40% of the visits. All cats (n=3) with acute kidney injury (AKI) at admission developed worsening AKI and reperfusion injury. Of the remaining two visits, one developed a non-fatal AKI. Cats' survival to discharge was 40%. CONCLUSIONS: Systemic thrombolysis with tPA seems to be effective and safe in dogs. More investigation is needed in cats.

Optimizing the Properties of Hybrids Based on Graphene Oxide for Carbon Dioxide Capture.

The reduction of CO2 emissions and its elimination from the atmosphere has become one of the major problems worldwide, since CO2 is the main cause of the greenhouse effect and climate change. In recent years, a great number of carbonaceous materials that can be used as CO2 adsorbents have been synthesized. The strategy is usually to synthesize the materials and determine their adsorption capacity without studying previously the factors that influence this capacity. In this work, different properties of the adsorbents are analyzed to study their influence on the CO2 adsorption capacity. For this purpose, 10 adsorbents have been synthesized using different strategies and characterized with X-ray photoelectron spectroscopy, X-ray diffraction, and micro-Raman spectroscopy. The percentage of sp2 carbons, the position of the D + D' peak of the second-order Raman spectrum, the micropore volume, and the grain size of the C sp2 domains have been related to the amount of CO2 adsorbed by the adsorbents. The results confirm a linear relationship between the volume of the micropores and the CO2 uptake and it proves that CO2 retention is favored in those materials that, in addition to having a high volume of micropores, also have low grain size of C.

n-3 polyunsaturated fatty acids in the regulation of adipose tissue browning and thermogenesis in obesity: Potential relationship with gut microbiota.

BACKGROUND: Obesity is a worldwide public health problem characterized by fat tissue accumulation, favouring adipose tissue and metabolic alterations. Increasing energy expenditure (EE) through brown adipose tissue activation and white adipose tissue (WAT) browning has gained relevance as a therapeutic approach. Different bioactive compounds, such as n-3 polyunsaturated fatty acids (PUFA), have been shown to induce those thermogenic effects. This process is regulated by the gut microbiota as well. Nevertheless, obesity is characterized by gut microbiota dysbiosis, which can be restored by weight loss and n-3 PUFA intake, among other factors. Knowledge gap: However, the role of the gut microbiota on the n-3 PUFA effect in inducing thermogenesis in obesity has not been fully elucidated. OBJECTIVE: This review aims to elucidate the potential implications of this interrelation on WAT browning adiposw sittue (BAT), BAT activity, and EE regulation in obesity models.

Inverse relationship between diffusion coefficient and mass for a free particle system: Approach by using maximum caliber principle and Monte Carlo simulations.

A derivation of the diffusion equation is presented using the maximum caliber principle and the continuity equation for a system composed of paths traveled by a free particle in a time interval. By identifying the diffusion coefficient in the obtained diffusion equation, it is shown that there is an inverse proportionality relationship concerning the particle's mass so that a higher mass is related to lower diffusion, and the lower mass is connected to the higher diffusion. This relationship is also shown using Monte Carlo simulations to sample the path space for a free particle system and then using the time slicing equation to obtain the probability of the particle position for each time showing the diffusion behavior for different masses.

Sea Level and Socioeconomic Uncertainty Drives High-End Coastal Adaptation Costs.

Sea-level rise and associated flood hazards pose severe risks to the millions of people globally living in coastal zones. Models representing coastal adaptation and impacts are important tools to inform the design of strategies to manage these risks. Representing the often deep uncertainties influencing these risks poses nontrivial challenges. A common uncertainty characterization approach is to use a few benchmark cases to represent the range and relative probabilities of the set of possible outcomes. This has been done in coastal adaptation studies, for example, by using low, moderate, and high percentiles of an input of interest, like sea-level changes. A key consideration is how this simplified characterization of uncertainty influences the distributions of estimated coastal impacts. Here, we show that using only a few benchmark percentiles to represent uncertainty in future sea-level change can lead to overconfident projections and underestimate high-end risks as compared to using full ensembles for sea-level change and socioeconomic parametric uncertainties. When uncertainty in future sea level is characterized by low, moderate, and high percentiles of global mean sea-level rise, estimates of high-end (95th percentile) damages are underestimated by between 18% (SSP1-2.6) and 46% (SSP5-8.5). Additionally, using the 5th and 95th percentiles of sea-level scenarios underestimates the 5%-95% width of the distribution of adaptation costs by a factor ranging from about two to four, depending on SSP-RCP pathway. The resulting underestimation of the uncertainty range in adaptation costs can bias adaptation and mitigation decision-making.

Cumplimiento de la dieta mediterránea en el personal sanitario de la provincia de Las Palmas / Adherence to the Mediterranean diet in health personnel from the province of Las Palmas

Antecedentes y objetivos Demostrado efecto protector de la dieta mediterránea, se evaluó su seguimiento y la influencia de distintos factores en el cumplimiento dietético. Material y métodos Se realizó un estudio transversal con encuestas anónimas para obtener datos sobre características demográficas, actividad laboral, antecedentes de factores de riesgo cardiovascular, consumo de alcohol y tabaco, actividad física y consumo de dieta mediterránea. Se evaluó el cumplimiento por medio del cuestionario 14-point Mediterranean Diet Adherence Score (MEDAS) y los factores estadísticamente relacionados con el mismo. Resultados y conclusiones De 922 personas encuestadas (664 mujeres) de edad media 42,61 años (rango: 20 a 69 años), un 61,2% mostró buen cumplimiento. De manera independiente, el consumo de la dieta mediterránea se asoció con la categoría profesional, siendo superior en el personal médico (OR = 1,92; IC 95%: 1,20 a 3,06; p = 0,01) y de enfermería (OR = 1,67; IC 95%: 1,08 a 2,57) comparado con los técnicos auxiliares en cuidados de enfermería. Además, se relacionó con realizar actividad física (OR = 1,78; IC 95%: 1,29 a 2,47; p < 0,001) y cocinar en casa (OR = 1,35; IC 95%: 1,00 a 1,80; p = 0,05). Sin embargo, no se asoció significativamente con la edad, el sexo ni con la presencia de comorbilidades, con las características de la jornada laboral, ni con el consumo de alcohol ni tabaco. Convendría cuantificar el conocimiento sobre la dieta e incrementar los programas educativos, fomentando el ejercicio y el hábito culinario (AU)

Introduction and objectives Given the proven protective effect of the Mediterranean Diet, adherence to it by healthcare personnel and the influence of different factors on dietary compliance were evaluated. Methods A cross-sectional study was conducted on healthcare personnel, obtaining the data through anonymous surveys that collected demographic characteristics, professional activity, history of cardiovascular risk factors, alcohol, and tobacco consumption, physical activity, and adherence to the Mediterranean Diet, using the 14-point Mediterranean Diet Adherence Score (MEDAS). Adherence and related factors were measured. Results and conclusions Of a total of 922 respondents (664 women) mean aged 42.61 years (range 20 to 69), 61.2% showed a good adherence to the Mediterranean Diet. Adherence was significantly associated with the professional categories of physicians (OR = 1.92; 95% CI: 1.20-3.06; p = 0.01) and nurses (OR = 1.67; 95% CI: 1.08-2.57). Furthermore, it was associated with physical exercise (OR = 1.78; 95% CI: 1.29 – 2.47; p < 0.001) and cooking at home (OR = 1.35; 95% CI: 1.00 – 1.80; p = 0.05). However, adherence was not significantly associated with age or sex, comorbidities, working hours, alcohol, or tobacco consumption. Quantifying knowledge of the diet would be useful, as well as increasing educational programs, promoting physical exercise and cooking habits (AU)

Subduction zone fluids and arc magmas conducted by lithospheric deformed regions beneath the central Andes.

Dehydration of the oceanic subducting slab promotes the formation of magmatic arcs, intra-slab intermediate-depth seismicity, and hydration of the overlying mantle wedge. However, the complex permeability structure of the overriding plate controls the magma and fluid migration and their accumulation at shallower depths. In this regard, mapping the inner structure of the overriding crust and mantle is crucial to understand the magmatic and hydrological processes in subduction zones. We integrate 3-D P-wave, [Formula: see text], and electrical resistivity tomographic models of the northern Chilean subduction zone to map the magmatic and fluids derived from the subducting oceanic Nazca plate. Results show a continental crust relatively thick (50-65 km) characterized by a lower zone of high [Formula: see text] values (7.2-7.6 km/s), which is interpreted as the presence of plutonic rocks. The mantle lithospheric wedge is weakly hydrated ([Formula: see text] = 1.75-1.8) while the forearc continental crust is traversed by regions of reduced electrical resistivity values ([Formula: see text] [Formula: see text]) interpreted as zones of relatively high permeability/fracturing and fluid content. These regions spatially correlate with upper plate trans-lithospheric deformation zones. Ascending melts accumulate preferentially in the back-arc, whereas hydrothermal systems form trenchward of the volcanic arc. The results highlight the complex permeability structure of the upper South American plate.

A facile approach for tuning optical and surface properties of novel biobased Alginate/POTE handleable films via solvent vapor exposure.

Novel biobased films consisting of alginate blends with poly (octanoic acid 2-thiophen-3-yl-ethyl ester) (POTE), a conducting polymer, were prepared by solution casting, and their optical, morphological, thermal, and surface properties were studied. Using UV-visible spectroscopy, atomic force microscopy (AFM), and scanning electron microscopy (SEM), the effects of tetrahydrofuran solvent vapors on the optical properties and surface morphology of biobased films with different POTE contents were studied. Results indicate that morphological rearrangements of POTE take place during the process of solvent exposure. Specifically, the solvent vapor induced the formation of POTE small crystalline domains, which allows envisioning the potential of tuning UV-visible absorbance and wettability behavior of biobased films. Finally, theoretical electronic calculations (specifically frontier molecular orbitals analysis) provided consistent evidence on POTE's preferential orientation and selectivity toward the THF-vapor medium.
