Abstract: The person of the therapist: Spanish validation of the Personal Style of the Therapist Questionnaire (PST-Q). The Personal Style of the Therapist Questionnaire (PST-Q) is an instrument with more than 20 years of theoretical and empirical developments at the international scenario, especially in Latin America. The main goal of the study was to provide preliminary evidence on its psychometric properties and factorial structure in a sample of Spanish licensed clinical psychologists (N = 350). 7 confirmatory factor analysis were performed to found a 20-item and 5-factor solution that had the best fit indices and internal consistency values. The original abbreviated model of the PST-Q was partially confirmed, since item 28 had to be eliminated because it had a factor weight less than .30. The alpha values were slightly lower than the original, but equivalent to those of the Portuguese validation. The implications of the findings for training and research in psychotherapy and clinical psychology are discussed.Keywords: Personal style of the therapist; PST-Q; practice-oriented research; clinical psychology; psychotherapy.

Rhopalosiphum rufiabdominale (Sasaki) dan Tetraneura nigriabdominalis (Sasaki) merupakan spesies kutudaun yang ditemukan hidup di akar tanaman padi. Informasi tentang kisaran inang dan biologi R. rufiabdominale relatif lebih banyak diketahui dibandingkan dengan T. nigriabdominalis. Penelitian ini bertujuan mengetahui biologi dan statistik demografi kutudaun R. rufiabdominalis dan T. nigriabdominalis yang hidup di akar tanaman padi. Kutudaun yang diperoleh dari akar padi sawah di Leuwiliang, Kabupaten Bogor dipelihara dan diperbanyak pada akar padi varietas Ciherang di laboratorium. Setiap nimfa instar satu kutudaun cohort yang sama diinfestasikan ke akar padi di dalam 60 wadah plastik untuk pengamatan biologi dan peubah statistik demografi. Peluang hidup (lx), keperidian harian (mx), dan rata-rata jumlah nimfa kutudaun yang dilahirkan oleh imago setiap harinya pada umur (x) digunakan untuk menghitung parameter statistik demografi. Hasil penelitian menunjukkan bahwa kedua spesies kutudaun tersebut masing-masing memiliki 4 stadia nimfa. Siklus hidup dan lama hidup R. rufiabdominale ialah 4,98 hari dan 15,94 hari dengan keperidian 67,44; Sedangkan siklus hidup dan lama hidup T. nigriabdominalis ialah 5,25 hari dan 18,11 hari dengan keperidian 11,11. Kutu daun R. rufiabdominale memiliki tingkat pertumbuhan intrinsik (r) 0,46 hari dan waktu berlipat ganda (DT) 1,50 hari; Sedangkan T. nigriabdominalis memiliki tingkat pertumbuhan intrinsik 0,14 hari dan waktu berlipat ganda 4,99 hari. Hasil penelitian ini menunjukkan bahwa meskipun lama siklus hidup kedua spesies kutudaun hampir sama, namun populasi R. rufiabdominale berkembang 3,5 kali lebih cepat dibandingkan dengan T. nigriabdominalis dan oleh karenanya berpotensi menjadi hama penting pada tanaman padi.

Published: January 2020

Aim: The aim of this study is to evaluate the antioxidant properties and protective effects of aqueous anti-ulcer drug (AQAUD) against aspirin-induced gastric ulcer in albino rats.
Methods: In this study, 30 male albino rats were divided into 5 groups of 6 each. Rats in group I served as normal control and received food and water. Animals in group II received food and water in addition to aspirin (400 mg/kg.b.wt) orally on the 14th day. Rats in groups III, IV and V received “AQAUD” (250 mg/kg.b.wt), (500 mg/kg.b.wt) and Omeprazole (20 mg/kg.b.wt) respectively for 14 days and aspirin (400 mg/kg.b.wt) orally on the 14th day. In vitro antioxidant property of “AQAUD” was assessed by its nitric oxide and hydroxyl radicals scavenging properties. The ulcer protective effect of “AQAUD” was assessed by determining the free and total acidity, ulcer index and % protection in the stomach content. The antioxidant potential in animals was evaluated by determining the concentrations of malondialdehyde and reduced glutathione. Superoxide dismutase and catalase activities were assayed in the stomach homogenates to further assess antioxidant potential. Total phenolics and flavonoid compounds were quantified to know the antioxidant content. Histopathological assessment of the gastric mucosa was used to assess the protective potentials of “AQAUD”. Data were analyzed using Statistical Package for Social Science (SPSS) version 21.
Results: The results revealed that free acidity and ulcer indexes were significantly (p<0.05) reduced by “AQAUD”. There was a significant decrease in SOD activity of the stomach homogenates when compared to the aspirin group, with values for “AQAUD” 250 mg/kg.b.wt and “AQAUD” 500 mg/kg b.wt as 37.24±5.39ux10-2/mg protein and 23.64±2.91ux10-2/mg protein respectively. Result of acute toxicity testing showed that “AQAUD” is generally safe up to 5000 mg/kg b.wt.
Conclusion: The results revealed that treatment with aspirin caused loss of gland architecture with erosion of epithelial layer, but AQAUD treatment ameliorated the effect of aspirin administration. The study revealed that “AQAUD” has considerable antioxidant potentials and can effectively protect against gastric ulcers.

Masculinidades Negras no Livro Didático de Língua Portuguesa
Authors: Oliveira Fábio Araújo 
Published: January 2020

<p>Neste trabalho, analisamos o discurso sobre as masculinidades negras no livro didático de língua portuguesa do ensino fundamental no Brasil. Para isso, utilizamos a teoria da análise do discurso pecheutiana. Os livros selecionados para análise são dois: um do 5º e outro do 9º ano que estão entre os mais solicitados pelos professores da rede pública e comprados pelo Programa Nacional do Livro Didático (PNLD) em suas duas últimas edições. Como o livro didático é um importante instrumento para a educação escolar formal de crianças e adolescentes, considerando a sua utilização e o seu predomínio nesse processo de escolarização, bem como o seu potencial em “transmissão” de ideologia, entendemos que é de suma importância a sua análise em vários aspectos. No caso do livro didático de português, há uma especificidade: ele “veicula” ideologias muito diversas, que, inclusive, podem ser conflitantes, se considerarmos o fato de que é um instrumento que traz textos de todos os tipos, de todos os gêneros, de diversas áreas e de diversas épocas. No que diz respeito às masculinidades negras, a questão essencial que se coloca é se há representação dessas subjetividades e, caso haja, como ela é construída e quais sentidos “veiculam”. Consideramos essencial avaliar como o livro didático de português trata a questão das masculinidades negras, se ele reproduz ou questiona sentidos considerados tóxicos do masculino; se está aberto para uma diversidade das masculinidades, considerando possibilidades múltiplas de sexualidade, gênero e classe, por exemplo; e se reproduz, silencia ou traz à reflexão questões ligadas ao racismo.</p>

AbstractPurposeThis paper outlines the commissioning of the Varian (VMS, Varian Medical Systems, Palo Alto, CA) Universal Interstitial Cylinder (UIC) applicator set for Ir‐192 HDR brachytherapy. The UIC was commissioned for use with CT and MRI and a custom phantom was designed to avoid the introduction of water‐like materials into the needle guide tracks. Various marker strands were investigated to determine which allowed the most accurate reconstruction of source positions.MethodsPlanar kV and MV imaging, along with physical measurements and autoradiographs, were used to commission the physical dimensions of all components of the UIC applicator set. CT and MR imaging was used to further commission one configuration of the UIC with UCP and eight interstitial needles in a simulated clinical setup using a GYN phantom. Three different methods of channel identification were compared – no radio opaque markers, VMS numbered markers, or nylon coated stainless steel leader wires – to see which best aided in channel identification and image registration. An HDR MRI Lumen marker (C4 Imaging, LLC) was used to verify any applicator rotation on MR scans during image registration. Three types of GYN phantoms were investigated – wet towel, gelatin, and ground beef. Dimensions of all components were compared with vendor provided information, including the solid applicator models, which are based on the computer‐aided design model files of the specific applicators.ResultsThe dimensions of the applicators could be validated using physical measurements, kV and MV planar imaging, and CT scans. The ground beef based GYN phantom best eliminated the introduction of water into the needle guide tracks that was found when using a water or gel‐based phantom. CT scans using no radio opaque markers did not allow the plastic needles to be visualized well enough to digitize source positions. CT scans with VMS markers showed significant artifact. CT scans with the nylon coated stainless steel wires provided the best visibility of the needle locations to aid in digitizing source positions. The use of an MR marker allowed the channel to be identified on the MR scan and confirm rotation for image registration.ConclusionsThe UIC set and applicator configuration was commissioned for CT and MR based treatment planning. The plastic components of the UIC applicator set pose challenges to the commissioning process but the use of radio opaque markers seen on CT combined with MR image registration allow the source positions within the needles, as well as the location of the end of the needles, to be digitized appropriately. A ground beef phantom minimized the fluid introduced into the needle guide track, minimizing any unintended MR and CT signal in the needle guide tracks.
Harnessing the Potential of Spider Silk Proteins for Biomedical Applications: from Native Silk Fibers to Designed Bioactive Materials
Authors: Fang Shiyu , Li Yue , Kou Songzi , Sun Fei 
Published: December 2024

AbstractSpider silk has only been used anecdotally throughout human history, owing to limited supply from natural sources and recalcitrance toward biochemical functionalization. Recent advances in materials synthetic biology have ameliorated the challenges of mass‐producing spider silk and have thus paved the way for reengineering and redesigning these materials for real‐world applications. Here, an update is presented on the development of biomaterials comprising spider silk proteins within the past five years and the respective chemical and genetic approaches behind these developments. Potential applications are further highlighted in areas such as 3‐dimension (3D) cell culturing, drug delivery, theranostics, wound healing, tissue engineering, anti‐infection, and so on. By providing some glimpses into the latest innovations centered around spider silk proteins, as well as the challenges facing their biomedical applications, it is hoped that this will inspire more translational studies of these materials for real‐world impact.

Published: December 2024

AbstractImplantable medical electronic devices (IMEDs) have attracted great attention and shown versatility for solving clinical problems ranging from real‐time monitoring of physiological/ pathological states to electrical stimulation therapy and from monitoring brain cell activity to deep brain stimulation. The ongoing challenge is to select appropriate materials in target device configuration for biomedical applications. Currently, silk‐based biomaterials have been developed for the design of diagnostic and therapeutic electronic devices due to their excellent properties and abundant active sites in the structure. Herein, the aim is to summarize the structural characteristics, physicochemical properties, and bioactivities of natural silk biomaterials as well as their derived materials, with a particular focus on the silk‐based implantable biomedical electronic devices, such as implantable devices for invasive brain‐computer interfaces, neural recording, and in vivo electrostimulation. In addition, future opportunities and challenges are also envisioned, hoping to spark the interests of researchers in interdisciplinary fields such as biomaterials, clinical medicine, and electronics.

Published: December 2024

AbstractMitochondrial damage caused by external stimuli, such as high glucose levels and inflammation, results in excessive reactive oxygen species (ROS) production. Existing antioxidants can only scavenge ROS and cannot address the root cause of ROS production, namely, abnormal mitochondria. To overcome this limitation, the study develops a piezoelectric synergistic drug‐loaded nanosystem (BaTCG nanosystem) that targets mitochondria. The BaTCG nanosystem is delivered to mitochondria via triphenylphosphine modification, and generates current under the stimulation of ultrasound, thereby promoting mitochondrial autophagy and restoring mitochondrial homeostasis. In a model of diabetes‐related erectile dysfunction (ED), the BaTCG nanosystem, through the current induced by the piezoelectric effect, not only promoted mitophagy, thereby reducing ROS production, but also released long‐acting glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) to effectively reduce blood glucose levels and mitochondrial damage. Each component of this nanosystem functions individually as well as synergistically, thus facilitating corpus cavernosum repair and restoring erectile function. In conclusion, the findings offer a novel therapeutic strategy for diabetes‐related ED and a target for the treatment of diabetes‐related conditions with functionalized nanoparticles to regulate mitophagy.

Published: December 2024

ABSTRACTThe agricultural sector in Latin America plays a vital role in ensuring food security while impacting the environment. However, there remains a lack of analysis regarding the inputs responsible for pollution within its sub‐technologies. Hence, this article aims to assess agricultural green total factor productivity (TFP) through a novel decomposition of the Luenberger–Hicks–Moorsteen (LHM) indicator. Utilizing panel data from 23 Latin American countries covering the period from 2000 to 2019, our study reveals that green TFP has achieved a consistent annual growth rate of 0.71%. Specifically, technical efficiency change (TEC) accounts for 0.26% of the TFP, with the technical change component (TP) and scale efficiency change (SEC) contributing 0.74% and 0.30%, respectively. These findings suggest that Latin American countries have increasingly utilized agricultural inputs more efficiently over time. The results provide valuable insights for developing innovative measures and effective policy strategies to promote sustainability in the agricultural sector.

AbstractSingle‐atom catalysts (SACs) inherit the merit of both homogeneous and heterogeneous systems with atomically dispersed mononuclear metal centers on the solid supports. Herein, we developed an Ir‐SAC catalyst via the polymerization of an active homogeneous 2‐picolinylhydrazone ligand‐based iridium (Ir) metal complex. Such catalysts provide great stabilization against migration and agglomeration due to the strong covalent C−C bond linkage of active complexes and the polymer matrix. This Ir‐SAC catalyst shows excellent selectivity towards glycerol to lactic acid conversion with a remarkable recyclability to offer an unprecedentedly high TON of over 104 million under optimized conditions.

AbstractWährend Molybdän‐Distickstoffkomplexe eine wichtige Rolle als katalytische Modellsysteme der Nitrogenase gespielt haben, erwiesen sich die entsprechenden Wolframkomplexe in den meisten Fällen als katalytisch inaktiv. Hier stellen wir einen modifizierten pentadentaten tetrapodalen (pentaPod) Phosphinliganden vor, bei dem zwei Dimethylphosphinogruppen des pentaPodMe (P5Me)‐Liganden durch Phospholan (Pln) ersetzt wurden. Während der daraus abgeleitete Molybdänkomplex [Mo(N2)P5Pln] 22 Äquivalente NH3 erzeugt, generiert der analoge Wolframkomplexe [W(N2)P5Pln] 7 Äquivalente NH3 aus N2 in Gegenwart von 180 Äquivalenten SmI2(THF)2/H2O. Letzterer ist damit der erste Wolframkomplex, der N2 chemokatalytisch in NH3 umwandelt. Im Gegensatz dazu erzeugt der Wolframkomplex [W(N2)P5Me] geringfügig überstöchiometrisch Ammoniak aus N2. Die Gründe für diese Reaktivitätsunterschiede werden mit Hilfe von spektroskopischen und elektrochemischen Methoden untersucht.

AbstractFluormethyltriflat (Superfluormethyl, SFM, FCH2OSO2CF3) und Fluormethylfluorsulfonat (Magisches Fluormethyl, MFM, FCH2OSO2CF3) sind zwei leicht synthetisierbare, leistungsstarke und nicht ozonabbauende Fluormethylierungsreagenzien. Sie sind Analoga der bekannten und weit verbreiteten Methylierungsreagenzien H3COSO2CF3 und H3COSO2F. Sowohl SFM als auch MFM wurden vollständig mittels multinuklearer NMR‐Spektroskopie (1H, 13C, 17O, 19F, 33S) charakterisiert. Ihre Strukturen im festen Zustand wurden an in situ gezüchteten Kristallen durch Röntgenbeugung und in der Gasphase mittels Elektronenbeugung bestimmt. Die Fluormethylierungskraft von SFM und MFM wurde anhand der Reaktivität gegenüber Chalkogen‐Nukleophilen unterschiedlicher Nukleophilie nachgewiesen. Alle fluormethylierten Produkte wurden als reine Verbindungen isoliert und durch NMR‐ und Schwingungsspektroskopie sowie in einigen Fällen durch Einkristall‐Röntgenbeugung charakterisiert.
