Ferroelectric polymorphic phenomena in the layered antiferromagnet Cu(OH)2.

Ferroic orders and their associated structural phase transitions are paramount in the understanding of a multitude of unconventional condensed matter phenomena. On this note, our investigation focuses on the polymorphic ferroelectric (FE) phase transitions of Copper(II) hydroxide, Cu(OH)2, considering an antiferromagnetic ground state. By employing the first-principles studies and group theory analysis, we have provided a systematic theoretical investigation of vibrational properties in the hypotheticalCmcmhigh-symmetry phase to unveil the symmetry-allowed ferroic phases. We identified a non-polar to polar (Cmc21) phase transition, in which the displacive transformation is primarily responsible for the phase change induced by twoB1u(i.e.Γ2-) phonon modes within the centrosymmetric phase. We also observed the existence of two polar structures with the same space group and different degrees of polarization (i.e.Ps= 3.06µC·cm-2andPs= 42.41µC·cm-2), emerging from the high symmetry non-polar structure. According to the structural analysis the FE order, of a geometric nature, is driven by theΓ2-mode in which the O- and H-sites displacements lead the polar distortion with a minor contribution from the Cu-sites. Interestingly, the 3d9:Cu2+Jahn-Teller distortion coupled with the orientational shifts of O-H atoms enhances the polarization.

Cultivo e uso racional de plantas medicinais e fitoterápicos / Cultivation and rational use of medicinal and herbal plants / Cultivo y uso racional de plantas medicinales y herbáceas

A utilização de plantas medicinais como alternativa terapêutica vem atingindo um público cada vez maior.

Ex vivo treatment with fucoidan of mononuclear cells from SARS-CoV-2 infected patients.

COVID-19 is a worldwide health emergency, therapy for this disease is based on antiviral drugs and immunomodulators, however, there is no treatment to effectively reduce the COVID-19 mortality rate. Fucoidan is a polysaccharide obtained from marine brown algae, with anti-inflammatory, antiviral, and immune-enhancing properties, thus, fucoidan may be used as an alternative treatment (complementary to prescribed medical therapy) for the recovery of COVID-19.  This work aimed to determine the effects of ex-vivo treatment with fucoidan on cytotoxicity, apoptosis, necrosis, and senescence, besides functional parameters of calcium flux and mitochondrial membrane potential (ΔΨm) on human peripheral blood mononuclear cells isolated from SARS-CoV-2 infected, recovered and healthy subjects. Data suggest that fucoidan does not exert cytotoxicity or senescence, however, it induces the increment of intracellular calcium flux. Additionally, fucoidan promotes recovery of ΔΨm in PBMCs from COVID-19 recovered females. Data suggest that fucoidan could ameliorate the immune response in COVID-19 patients.

Unusual winter Saharan dust intrusions at Northwest Spain: Air quality, radiative and health impacts.

Saharan air masses can transport high amounts of mineral dust particles and biological material to the Iberian Peninsula. During winter, this kind of events is not very frequent and usually does not reach the northwest of the Peninsula. However, between 21 and 22 February 2016 and between 22 and 23 February 2017, two exceptional events were registered in León (Spain), which severely affected air quality. An integrative approach including: i) typical synoptic conditions; ii) aerosol chemical composition; iii) particle size distributions; iv) pollen concentration; v) aerosol optical depth (AOD); vi) radiative forcing and vii) estimation of the impact of aerosols in the respiratory tract, was carried out. In the global characterization of these events, the exceedance of the PM10 daily limit value, an increase in the coarse mode and a rise in the iron concentration were observed. On the 2016 event, an AOD and extinction-related Ångström exponent clearly characteristic of desert aerosol (1.1 and 0.05, respectively) were registered. Furthermore, pollen grains not typical of flowering plants in this period were identified. The chemical analysis of the aerosol from the 2017 event allowed us to confirm the presence of the main elements associated with mineral sources (aluminum, calcium, and silica concentrations). An increase in the SO42-, NO3- and Cl- concentrations during the Saharan dust intrusion was also noted. However, in this event, there was no presence of atypical pollen types. The estimated dust radiative forcing traduced a cooling effect for surface and atmosphere during both events, corroborated by trends of radiative flux measurements. The estimated impact on the respiratory tract regions of the high levels of particulate matter during both Saharan dust intrusions showed high levels for the respirable fraction.

[Long-term individual cognitive stimulation program in patients with mild neurocognitive disorder: a pilot study]. / Programa de estimulacion cognitiva individual de larga duracion para personas con trastorno neurocognitivo leve: estudio piloto.

INTRODUCTION: There is evidence to suggest that cognitive stimulation produces cognitive benefits in people with mild neurocognitive disorder. However, the effect has been previously demonstrated to be minimal to moderate and the effect of long-term individual interventions, namely on specific cognitive domains, is unknown. AIM: To assess the efficacy, feasibility and acceptability of a long-term individual cognitive stimulation intervention for patients with mild neurocognitive disorder. PATIENTS AND METHODS: Patients (n = 30) with mild neurocognitive disorder were assigned to a cognitive stimulation intervention group (n = 15) or to a control group (n = 15). The intervention consisted of 88 individual sessions, approximately 45 minutes long, with two sessions per week. External evaluators assessed the level of alteration in cognitive performance, depressive symptoms and the level of independence in the performance of basic activities of daily living. RESULTS: After the intervention, a significant improvement was found in the intervention group compared to the control group in overall cognitive performance (d = 0.83), specifically in the language domain (d until 1.50). There were also lower depressive symptoms in the intervention group compared to the control group (d = 0.93). Only 6.7% of the participants dropped out the study, with participants attending a mean of 83 ± 12.1 sessions. CONCLUSIONS: The results support the efficacy, feasibility and acceptability of the intervention for mild neurocognitive disorder and justify a randomized controlled trial of the program with a larger sample.

TITLE: Programa de estimulacion cognitiva individual de larga duracion para personas con trastorno neurocognitivo leve: estudio piloto.Introduccion. Existen evidencias que sugieren que la estimulacion cognitiva produce beneficios cognitivos en personas con trastorno neurocognitivo leve. Sin embargo, el tamaño del efecto encontrado es de pequeño a moderado, y se desconoce el efecto de las intervenciones individuales de larga duracion y, mas concretamente, sobre dominios cognitivos especificos. Objetivo. Evaluar la eficacia, viabilidad y aceptabilidad de una intervencion de estimulacion cognitiva individual de larga duracion para personas con trastorno neurocognitivo leve. Pacientes y metodos. Un total de 30 personas con trastorno neurocognitivo leve fueron asignadas a un grupo de intervencion de estimulacion cognitiva (n = 15) o a un grupo control (n = 15). La intervencion consistio en 88 sesiones individuales de unos 45 minutos, con una periodicidad de dos veces por semana. Evaluadores independientes valoraron el nivel de rendimiento cognitivo, los sintomas depresivos y el nivel de autonomia en la realizacion de actividades basicas de la vida diaria. Resultados. Tras la intervencion, se encontro una mejoria significativa en el grupo de intervencion en comparacion con el grupo control en el rendimiento cognitivo global (d = 0,83), concretamente en el dominio del lenguaje (d hasta 1,50), y una menor sintomatologia depresiva en el grupo de intervencion en comparacion con el control (d = 0,93). Solo un 6,7% de los participantes abandono el estudio, asistiendo a un promedio de 83 ± 12,1 sesiones. Conclusiones. Los resultados apoyan la eficacia, viabilidad y aceptabilidad de la intervencion, y justifican la realizacion de un ensayo controlado aleatorizado aplicado a una muestra mayor.

System Failure: Work Organization and Injury Outcomes among Latino Forest Workers.

OBJECTIVES: Forestry services is a hazardous industry with high job-related injury, illness, and fatality rates. The Northwest workforce is largely Spanish-speaking, Latino, and immigrant, working in poor conditions with insufficient attention paid to safety and health. Institutional racism fundamentally shapes the structural vulnerability of Latino immigrant workers. Given this context, we sought to understand how workplace organizational factors and safety climate affect job-related injuries in this industry. METHODS: We developed 23 case studies from personal interviews after selecting from an initial participant survey pool of 99 Latino forest workers in southern Oregon who had been injured at work in the previous 2 years. Workers were recruited through snowball sampling and door-to-door canvassing. Questions spanned work conditions, tasks, employer safety practices, injury experience, medical treatment, and workers' compensation benefits. RESULTS: Workers reported broken bones, chainsaw lacerations, back pain, heat and pesticide illnesses, and other occupational injuries. One-third of the cases fell into a Systems Functional category in which they reported their injuries to their supervisors and received medical treatment and workers' compensation benefits. The remaining two-thirds experienced System Failures with difficulties in receiving medical treatment and/or workers' compensation benefits, employer direction to not report, being fired, or seeking alternative home remedies. CONCLUSION: Workers employed by companies with more indicators of safety climate were more likely to obtain adequate treatment for their injuries and fully recover. Workers for whom interpretation at medical exams was provided by someone unaffiliated with their employers also reported better treatment and recovery outcomes.

Optimization and scale-up of an LED-illuminated microalgal photobioreactor for wastewater treatment.

The use of light-emitting diode (LED)-illuminated photobioreactors with microalgae has been extensively studied for wastewater treatment. Most studies have used isolated microalgae species; however, this practice does not match the reality of conditions in wastewater treatment plants. Operational conditions that promote greater growth of algal biomass and that remove pollutants most effectively are disputed in the literature. In this context, LED-illuminated photobioreactors with microalgae were evaluated using multivariate analysis in order to optimize removal of pollutants (nitrogen, phosphorus, and carbonaceous organic matter). Three variables were evaluated: operating time, LED wavelength, and luminous flux intensity. A microalgae consortium was used in the photobioreactor. In addition to the LED-illuminated photobioreactors, control photobioreactors illuminated by sunlight were also operated. Using the results obtained in the optimization, a scaled-up reactor approximately 8.5 times larger in volume was operated to evaluate if the behavior would be maintained. The best operational conditions for the removal of pollutants were observed in LED-illuminated photobioreactors operated under a light intensity of 700 µmol·m-2s-1 for 15 days. Under these conditions, it was possible to remove 89.97% of carbonaceous organic matter, 86.50% of nitrogen, and 30.64% of phosphorus. The scaled-up photobioreactor operated with similar performance.

ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies: an infectious diseases perspective (Cell surface receptors and associated signaling pathways).

BACKGROUND: The present review is part of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group for Infections in Compromised Hosts (ESGICH) consensus document on the safety of targeted and biologic therapies. AIMS: To review, from an infectious diseases perspective, the safety profile of therapies targeting cell surface receptors and associated signaling pathways among cancer patients and to suggest preventive recommendations. SOURCES: Computer-based Medline searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: Vascular endothelial growth factor (VEGF)-targeted agents (bevacizumab and aflibercept) are associated with a meaningful increase in the risk of infection, likely due to drug-induced neutropaenia, although no clear benefit is expected from the universal use of anti-infective prophylaxis. VEGF tyrosine kinase inhibitors (i.e. sorafenib or sunitinib) do not seem to significantly affect host's susceptibility to infection, and universal anti-infective prophylaxis is not recommended either. Anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (cetuximab or panitumumab) induce neutropaenia and secondary skin and soft tissue infection in cases of severe papulopustular rash. Systemic antibiotics (doxycycline or minocycline) should be administered to prevent the latter complication, whereas no recommendation can be established on the benefit from antiviral, antifungal or anti-Pneumocystis prophylaxis. A lower risk of infection is reported for anti-ErbB2/HER2 monoclonal antibodies (trastuzumab and pertuzumab) and ErbB receptor tyrosine kinase inhibitors (including dual-EGFR/ErbB2 inhibitors such as lapatinib or neratinib) compared to conventional chemotherapy, presumably as a result of the decreased occurrence of drug-induced neutropaenia. IMPLICATIONS: With the exception of VEGF-targeted agents, the overall risk of infection associated with the reviewed therapies seems to be low.

Green coffee seed residue: A sustainable source of antioxidant compounds.

Oil extraction from green coffee seeds generates residual mass that is discarded by agribusiness and has not been previously studied. Bioactive secondary metabolites in coffee include antioxidant phenolic compounds, such as chlorogenic acids. Coffee seeds also contain caffeine, a pharmaceutically important methylxanthine. Here, we report the chemical profile, antioxidant activity, and cytotoxicity of hydroethanolic extracts of green Coffea arabica L. seed residue. The extracts of the green seeds and the residue have similar chemical profiles, containing the phenolic compounds chlorogenic acid and caffeine. Five monoacyl and three diacyl esters of trans-cinnamic acids and quinic acid were identified by ultra-performance liquid chromatography/electrospray ionization-quadruple time of flight mass spectrometry. The residue extract showed antioxidant potential in DPPH, ABTS, and pyranine assays and low cytotoxicity. Thus, coffee oil residue has great potential for use as a raw material in dietary supplements, cosmetic and pharmaceutical products, or as a source of bioactive compounds.

Traqueobronquitis y neumonía asociada a ventilación mecánica por Chryseobacterium indologenes / Tracheo-bronchitis and pneumonia associated with mechanical ventilation by Chryseobacterium indologenes

El desarrollo de infecciones nosocomiales por gérmenes intrínsecamente resistentes a carbapenemes aumenta la mortalidad y provoca un aumento del gasto sanitario. El conocimiento y estudio de estas infecciones es importante a la hora de mejorar protocolos de actuación epidemiológicos y terapéuticos. Presentamos un estudio descriptivo, de 8 casos clínicos de pacientes con diagnóstico de traqueobronquitis y neumonía asociada a ventilación mecánica (NAVM) por Chryseobacterium indologenes (CBI), durante un periodo de 5 años. En esta serie de casos el aislamiento del CBI se produjo a los 11 días de media (rango 7-18) de permanecer los enfermos conectados a ventilación mecánica. La duración media de los pacientes en ventilación mecánica fue de 36 días (rango 10-140). La estancia media en UCI fue de 49 días (rango 14-180). Únicamente en un paciente no se aisló copatógeno concurrente a la traqueobronquitis o la NAVM por CBI. La mortalidad intrahospitalaria fue del 25%. La infección respiratoria nosocomial secundaria a CBI en pacientes con ventilación mecánica ha aumentado en los últimos años, por lo que se debería incluir en el diangóstico diferencial de la NAMV (AU)

The development of nosocomial infections by germs resistant to carbapenems inherently increases mortality, and causes an increase in health spending. The knowledge and study of these infections is important in improving epidemiological and therapeutic performance protocols. We present a descriptive study of eight patients diagnosed with tracheobronchitis (TAVM) and pneumonia (NAVM) associated with mechanical ventilation Chryseobacterium indologenes (CBI), over a period of five years. CBI isolation occurred at 11 days on average (rank 7-18) of remaining patients connected to mechanical ventilation. The average length of patients on mechanical ventilation was 36 days (range 10-140). The average ICU stay was 49 days (range 14-180). There was no death at 28 days, but the intra-hospital mortality was 2 cases (25%). Nosocomial respiratory infection secondary to CBI in mechanically ventilated patients has increased in recent years, so that should be included in the differential diagnostic of NAMV (AU)

Peripheral and central antinociceptive effects of the butanolic fraction of Byrsonima verbascifolia leaves on nociception-induced models in mice.

Byrsonima verbascifolia (Malpighiaceae), commonly known as 'murici', is used in folk medicine, for example, in the treatment of inflammation. The anti-inflammatory activity of the butanolic fraction of B. verbascifolia leaves (BvBF) was previously reported by our group, and the present study was designed to evaluate their antinociceptive effects. BvBF (25, 50, and 100 mg/kg) administered intraperitoneally (i.p.) inhibited acetic acid induced abdominal writhing. In the formalin test, BvBF (10, 30 and 100 mg/kg, i.p.) caused a reduction in licking time in both the neurogenic and inflammatory phases. Moreover, we demonstrated that BvBF (30 and 100 mg/kg, i.p.) caused an increase in the latency to response in the hot-plate test. These results demonstrate that BvBF possesses marked peripheral and central antinociceptive activities. Pre-treatment with the non-selective receptor antagonist naloxone (5 mg/kg, i.p.) abolished the antinociceptive effects of BvBF (100 mg/kg, i.p.) in the neurogenic phase of the formalin and hot-plate tests. The anti-inflammatory activity of BvBF (previously reported) as well as the participation of the opioidergic system seems to be responsible, at least in part, for these antinociceptive effects. Finally, BvBF at the doses investigated (25, 50 and 100 mg/Kg) did not cause any toxicity signals, showing that the antinociceptive activity is devoid of sedative and hypomotility effects.

[Spanish adaptation of the 2016 European Guidelines on cardiovascular disease prevention in clinical practice]. / Adaptación española de las guías europeas de 2016 sobre prevención de la enfermedad cardiovascular en la práctica clínica.

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk. Diabetes mellitus confers a high risk, except for subjects with type 2 diabetes with less than <10 years of evolution, without other risk factors or complications, or type 1 diabetes of short evolution without complications. The decision to start pharmacological treatment of arterial hypertension will depend on the blood pressure level and the cardiovascular risk, taking into account the lesion of target organs. The guidelines don't recommend antiplatelet drugs in primary prevention because of the increased bleeding risk. The low adherence to the medication requires simplified therapeutic regimes and to identify and combat its causes. The guidelines highlight the responsibility of health professionals to take an active role in advocating evidence-based interventions at the population level, and propose effective interventions, at individual and population level, to promote a healthy diet, the practice of physical activity, the cessation of smoking and the protection against alcohol abuse.

Combined therapy with m-TOR-dependent and -independent autophagy inducers causes neurotoxicity in a mouse model of Machado-Joseph disease.

A major pathological hallmark in several neurodegenerative disorders, like polyglutamine disorders (polyQ), including Machado-Joseph disease (MJD), is the formation of protein aggregates. MJD is caused by a CAG repeat expansion in the ATXN3 gene, resulting in an abnormal protein, which is prone to misfolding and forms cytoplasmic and nuclear aggregates within neurons, ultimately inducing neurodegeneration. Treatment of proteinopathies with drugs that up-regulate autophagy has shown promising results in models of polyQ diseases. Temsirolimus (CCI-779) inhibits the mammalian target of rapamycin (m-TOR), while lithium chloride (LiCl) acts by inhibiting inositol monophosphatase, both being able to induce autophagy. We have previously shown that chronic treatment with LiCl (10.4 mg/kg) had limited effects in a transgenic MJD mouse model. Also, others have shown that CCI-779 had mild positive effects in a different mouse model of the disease. It has been suggested that the combination of mTOR-dependent and -independent autophagy inducers could be a more effective therapeutic approach. To further explore this avenue toward therapy, we treated CMVMJD135 transgenic mice with a conjugation of CCI-779 and LiCl, both at concentrations known to induce autophagy and not to be toxic. Surprisingly, this combined treatment proved to be deleterious to both wild-type (wt) and transgenic animals, failing to rescue their neurological symptoms and actually exerting neurotoxic effects. These results highlight the possible dangers of manipulating autophagy in the nervous system and suggest that a better understanding of the potential disruption in the autophagy pathway in MJD is required before successful long-term autophagy modulating therapies can be developed.

Assessment of antimicrobial activity in vitro of ethanolic extracts of Banisteriopsis anisandra (A. Juss. ) B. Gates (Malpighiaceae) / Avaliação da atividade antimicrobiana in vitro de extratos etanólicos de Banisteriopsis anisandra (A. Juss. ) B. Gates (Malpighiaceae)

The aim of this study was to evaluate the antimicrobial activity in vitro of ethanolic extracts of Banisteriopsis anisandra. Tests were performed using the extracts overlay method in the culture medium for phytopathogenic fungi Rhizoctonia solani and Fusarium oxysporum, and disk diffusion for the microorganisms Staphylococcus aureus and Candida albicans. Ethanolic extracts from leaves were prepared by maceration (extract I) and decoction (extract II) at 430.0, 215.0 and 107.5 mg/mL. The growth inhibition of R. solani and F. oxysporum was determined by calculating the mycelia growth speed rate (MGSR) and, in relation C. albicans and S. aureus, it was determined by measuring the inhibition halos. Extracts that caused significant inhibition were also tested at 86.0, 64.5, 43.0 and 21.5 mg/mL for C. albicans and S. aureus. Both extracts showed inhibitory activity on the microorganisms studied. Rizoctonia solani showed lower MGSR in the presence of extract II (107.5 mg/mL) and Fusarium oxysporum showed slight MGSR reduction in the presence of extract I (107.5 mg/mL) and II (107.5 and 215 mg/mL). Ethanolic extracts I and II inhibited the growth of C. albicans, with the highest rates of inhibition observed in the presence of extract II (215.0 mg/mL). For S. aureus, the highest inhibitory activity was observed in the presence of ethanolic extract II, prepared by decoction at 430.0 mg/mL. Results showed a promising antimicrobial activity of extracts of B. anisandra, which may contribute to further studies leading to a future development of medicines to treat human and plant diseases caused by these organisms.

O objetivo deste estudo foi avaliar a atividade antimicrobiana in vitro de extratos etanólicos de Banisteriopsis anisandra. Os testes foram realizados utilizando o método de sobreposição de extratos em meio de cultura para fungos fitopatogênicos Rhizoctonia solani e Fusarium oxysporum e de difusão em disco para os microrganismos Staphylococcus aureus e Candida albicans. Foram testados de extratos etanólicos de folhas preparados por maceração (extrato I) e decocção (extrato II), nas concentrações de 430,0; 215,0 e 107,5 mg/mL. A inibição do crescimento de R. solani e F. oxysporum foi determinada pelo cálculo do índice de velocidade de crescimento micelial (IVCM) e de C. albicans e S. aureus, por meio da medida da halos de inibição. Os extratos que causaram inibição significativa também foram testados nas concentrações de 86,0; 64,5; 43,0 e 21,5 mg/mL para C. albicans e S. aureus. Ambos os extratos mostraram atividade inibitória sobre os microrganismos estudados. Rizoctonia solani apresentou menor IVCM na presença do extrato II (107,5 mg/mL) e Fusarium oxysporum apresentou discreta redução no IVCM na presença do extrato I (107,5 mg/mL) e II (107,5 e 215 mg/mL). Extratos etanólicos I e II inibiram o crescimento de C. albicans, com as maiores taxas de inibição observadas na presença do extrato II (215,0 mg/mL). Para S. aureus a maior atividade inibitória foi observada na presença do extrato II, na concentração de 430 mg/mL. Os resultados mostraram promissora atividade antimicrobiana de extratos de B. anisandra, o que pode contribuir para estudos futuros visando o desenvolvimento de medicamentos para doenças humanas e de plantas causadas por estes microrganismos.
