Novas perspectivas sobre as fantasias inconscientes
Authors: Grotstein James S. 
Published: July 2023

O autor propõe novas perspectivas sobre as fantasias inconscientes. Procura demonstrar que os Sistemas Cs. e Ics. não funcionam em conflito, mas de modo complementar como oposições binárias. O Sistema Ics. tem dois maiores componentes, o Ics. não reprimido e o Ics. reprimido ou dinâmico, sendo o primeiro o Ics. platônico inato, e o último, o domínio das memórias reprimidas das experiências reais. O autor postula que o último é o depósito do processamento mental via sonhos e fantasias que se originam das atividades do primeiro. Os Sistemas Ics. e Cs. funcionam como braços opostos e cooperativos para interceptar “O” (a Verdade Absoluta sobre a Realidade Última). A formação da fantasia inconsciente, i.e., o funcionamento da função alfa, constitui o pensamento inconsciente. Os “atores” que desempenham as fantasias inconscientes são fantasmas ou demônios diversificados (ambos positivos e negativos) que representam um papel dramático esperando que, enquanto isso, alguém esteja lá para interpretar a sua pantomima, de modo que eles possam, como a esfinge em Oedipus Rex, ficar livres e retornar ao repertório. A interpretação psicanalítica da fantasia inconsciente os confirma e os completa, portanto, não desacreditando-os meramente. Sonhos e fantasias inconscientes são o nosso “serviço silencioso”.

Introduction: Malaria is a mosquito born infectious disease of human and other animals caused by parasitic protozoans belonging to the genus Plasmodium. Malaria parasite among school aged children is a disease that poses a great challenge to human health in Nigeria. Malaria contributes significantly to the burden of disease especially among children less than five years. Efforts aimed in controlling malaria, prevalence is still high.
Study Design: This study was designed to investigate the risk factor associated with malaria infection among school aged children in Jalingo and Sardauna LGAs of Taraba State, Nigeria.
Place and Duration of Study: Urban-Rural areas (Jalingo ans Sardauna LGA Taraba State Nigria), studied from July-December 2022.
Methodology: Structured questionnaire was used to obtain demographic information and Microscopy was also used to determine Parasitaemia level among the school aged children (2-15years). A total of 1000 children less than 15 years old from ten (10) selected communities of the study areas whose parent or guardian gives consent were selected.
Results: The results revealed that out of the 1000 subjects, 359(35.9%) were infected with malaria parasites. Ages between 2-5 year were found to have the highest prevalence of 212(21.2%) while age 11-15 group had least prevalence of 21(2.1%). The overall prevalence of malaria parasite was moderate among the study population. This is probably due to the seasonal variation in malaria parasite intensity and the good knowledge of caregivers on malaria infection and management.
Conclusion: There is therefore the need to sustain the current media and health facility-based campaigns on malaria prevention strategy and maintenance of clean environmental condition.

AbstractHybrid glasses derived from meltable metal‐organic frameworks (MOFs) have emerged as a new class of amorphous materials. Combining the porosity of MOFs with the processing ability of glasses, they are thought to enable a wholly new range of functional compounds. By way of example, it is demonstrated here how the intrinsic porosity of glasses obtained from zeolitic imidazolates (ZIFs) can be used to overcome the selectivity‐sensitivity trade‐off in electroactive gas sensing. For this, composites are fabricated in which metallophthalocyanines are embedded within a ZIF‐62 MOF glass matrix. Such a material enables the detection of gas species (or their absence) utilizing the pronounced electrochemical sensitivity of phthalocyanines. Thereby, the solid glass does not only stabilize and protect the active component, but also – through its retained, highly tunable porosity – ensures sensor selectivity by molecular sieving and targeted size exclusion of larger molecules. In addition, the hydrophobicity of the ZIF pore interior protects the active component from degradation caused by ambient humidity. Investigations of the structural, optical and electronic properties of the composite indicate that compoundation is purely physical, that is, chemical interactions between the compound partners are avoided and the individual properties of the hybrid glass matrix and the electroactive metallophthalocyanine are retained. Atmosphere‐controlled high‐temperature electrical impedance measurements reveal significant shifts in resistance in CO2 and Ar atmosphere as compared to airflow. These results provide a proof of concept for sensitive and selective gas sensors based on such composites.

AbstractNa3V2(PO4)3, based on multi‐electron reactions between V3+/V4+/V5+, is a promising cathode material for SIBs. However, its practical application is hampered by the inferior conductivity, large barrier of V4+/V5+, and stepwise phase transition. Herein, these issues are addressed by constructing a medium‐entropy material (Na3.2V1.1Ti0.2Al0.2Cr0.2Mn0.2Ni0.1(PO4)3, ME‐NVP) with strong ME─O bond and highly occupied Na2 sites. Benefiting from the medium‐entropy effect, ME‐NVP manifests a phase‐transition–free reaction mechanism, two reversible plateaus at 3.4 (V3+/V4+) and 4.0 V (V4+/V5+), and small volume change (2%) during Na+ insertion/extraction processes, as confirmed by comprehensive in/ex situ characterizations. Moreover, kinetics analysis illuminates the superior Na+ diffusion ability of ME‐NVP. Thus, the ME‐NVP cathode realizes remarkable rate capability of 67 mA h g−1 at 50C and a long‐term lifespan over 10 000 cycles (capacity retention of 81.3%). Theoretical calculations further illustrate that the weak binding of Na+ ion in the channel is responsible for the rapid Na+ diffusion, accounting for the superior reaction kinetics. Moreover, rigid MEO6 octahedral and feasible rearrangement of Na+ ions can suppress the phase transition, thus endowing an ultrastable ME‐NVP cathode. This work highlights the significant role of medium‐entropy engineering in advancing the output voltage, cycling stability, and rate capability of polyanionic cathodes.

Published: January 2025

AbstractIonic conductive hydrogels have emerged as an excellent option for constructing dielectric layers of interfacial iontronic sensors. Among these, gradient ionic hydrogels, due to the intrinsic gradient elastic modulus, can achieve a wide range of pressure responses. However, the fabrication of gradient hydrogels with optimal mechanical and sensing properties remains a challenge. In this study, it is discovered first that phytic acid (PA) interacts in remarkably distinct manners (i.e., plasticizing effects and phase separation) with different polymers (i.e., polyacrylamide and polyacrylic acid). This distinctive PA‐polymer interacting mechanism is innovatively utilized to construct a modulus gradient ionic hydrogel through a simple precursor solution infiltration approach. The gradient hydrogel‐based flexible pressure sensor not only achieves a high sensitivity (9.00 kPa−1, <15 kPa) and a broad sensing range (from ≈3.7 Pa to 1.2 MPa) simultaneously, but also exhibits superior low pressure sensing performance. It successfully recognizes the subtle pressure due to acoustic waves and airflow, as well as the moderate pressure due to speaking and finger pressing and the high magnitude of plantar pressure. In addition, the gradient hydrogel demonstrates remarkable antibacterial properties and biocompatibility. This functional hydrogel with excellent sensing performance and bioactivity exhibits exceptional potential for wearable sensing applications.

AbstractAn extensive examination of the nanoscale, crystallographic growth dynamics of the system, which is impacted by the thermal energy given to the GaN, is carried out to derive a deeper understanding of the growth kinetics, morphology and microstructure evolution, chemical bonding, and optical properties of Ga─O─N films. Thermal annealing of GaN films is performed in the temperature range of 900–1200 °C. Crystal structure, phase formation, chemical composition, surface morphology, and microstructure evolution of Ga─O─N films are investigated as a function of temperature. Increasing temperature induces surface oxidation, which results in the formation of stable β‐Ga2O3 phase in the GaN matrix, where the overall film composition evolves from nitride (GaN) to oxynitride (Ga─O─N). While GaN surfaces are smooth, planar, and featureless, oxidation induced granular‐to‐rod shaped morphology evolution is seen with increasing temperature to 1200 °C. The considerable texturing and stability of the nanocrystalline Ga─O─N on Si substrates can be attributed to the surface and interface driven modification because of thermal treatment. Corroborating with structure and chemical changes, Raman spectroscopic analyses also indicate that the chemical bonding evolution progresses from fully Ga─N bonds to Ga─O─N. While the GaN oxidation process starts with the formation of β‐Ga2O3 at an annealing temperature of 1000 °C, higher annealing temperatures induce structural distortion with the potential formation of Ga─O─N bonds. The structure‐phase‐chemical composition correlation, which will be useful for nanocrystalline materials for selective optoelectronic applications, is established in Ga─O─N films made by thermal treatment of GaN.

AbstractExceptional point degeneracies, which are spectral singularities of non‐Hermitian systems, have been widely utilized for building optical, mechanical, or electrical sensing systems with much larger responses than those utilizing Hermitian degeneracies. However, such systems suffer from enhanced noise, which negates the enhanced response and thus does not provide any improvement in signal‐to‐noise ratio. Recently, the coherent perfect absorber (CPA)‐laser, which also utilizes non‐Hermitian singularity, has been used in sensing systems resulting in better noise robustness and enhanced responsivity. Nonetheless, CPA‐laser (CPAL) implementation requires all system parameters to be immutable, which hinders progress toward their practical use for sensing purposes. Here, a tunable electronic CPA‐laser is reported that overcomes these obstacles providing ultrahigh sensitivity as validated in the experiments for monitoring arterial pressure and respiration. This CPAL sensing scheme utilizes inductive coupling between gain and loss sub‐components and thereby the whole system can be decomposed into an active reader and a passive sensor, which enables better tunability and performance compared to previously reported CPAL systems. Moreover, the proposed CPAL system exhibits better performance compared to exceptional point‐based systems having a similar circuit structure. This research paves the way for exploring electronic CPAL for sensing applications and may have a profound impact on the next‐generation, ultrasensitive electromagnetic sensing system.

AbstractAimAdjuvant chemotherapy (AC) is the standard treatment for patients with advanced gastric cancer (GC), yet the optimal timing for its initiation remains unclear. Besides, no studies have definitively established when AC should begin in patients receiving preoperative chemotherapy (PC). This study aimed to determine the optimal timing for initiating AC in patients with GC who underwent curative gastrectomy, either with or without PC.MethodsA total of 446 patients who underwent curative gastrectomy were evaluated, including 140 who received AC: 72 without PC and 68 with PC. Patients were categorized into two groups based on when they began AC: the early initiation group (within 8 weeks post‐surgery), and the late initiation group (8 weeks or later post‐surgery).ResultsIn the non‐PC cohort, the 3‐year relapse‐free survival (RFS) rates were 71% in the early group versus 56% in the late group (p = 0.49), while the 3‐year overall survival (OS) rates were 94% versus 73% (p = 0.003). Similar trends were observed in the PC cohort; the 3‐year RFS rates were 59% versus 19% (p = 0.002), and the 3‐year OS rates were 69% versus 48% (p = 0.02). Multivariate analysis identified pretherapeutic distant metastasis (p < 0.001) and delayed AC initiation (≥8 weeks) (p = 0.001) as independent predictors of worse prognosis.ConclusionDelayed initiation of AC is associated with significantly poorer postoperative survival in patients with GC, irrespective of whether PC was administered. These findings emphasize the importance of timely AC initiation to improve long‐term outcomes in this patient population.

Published: January 2025

AbstractThe simple and efficient conversion of carboxylic acids into structurally diverse organic molecules is highly desirable in chemical synthesis. This review covers recent developments in photocatalytic methodology for late‐stage transformations of complex carboxylic acids and their derivatives enabled by radical decarboxylation and deoxygenation, highlighting some representative and significant contributions in this field. These advancements are categorized based on the reactivity patterns exhibited by the carboxylic acids. Several activation modes to generate alkyl or aryl radical intermediates during decarboxylation of carboxylic acids are presented, namely, single‐electron transfer (SET) oxidation, ligand‐to‐metal charge transfer (LMCT), SET reduction, and energy transfer (EnT) processes. On the other hand, direct activation of C−O bonds in carboxylic acids mediated by phosphoranyl radicals has been discussed and illustrates their potential synthetic application for the synthesis of complex aldehydes, ketones and amides.

AbstractHydrogen sulfide (H2S) plays crucial inflammatory modulating roles, representing a promising candidate for anti‐inflammatory therapies. However, current H2S delivery approaches lack sufficient specificity against inflammatory response. Herein, regarding the overexpressed aminopeptidase N (APN) at the inflammation sites, an APN‐activated self‐immolative carbonyl sulfide (COS)/H2S donor (AlaCOS) was developed for inflammatory response‐specific H2S delivery. The compound showed sustained H2S generation upon APN activation in the presence of carbonic anhydrase (CA), and the responsiveness could be well regulated by modulating the amino acid sequence. Due to the inflammatory response‐specific sustained H2S delivery, AlaCOS provided potent anti‐inflammatory capability, which was further validated by RNA sequencing. In vivo experiments on a full‐thickness cutaneous wound murine model also showed the strong promoting effect on wound healing, mainly due to the regulation of the inflammatory response by AlaCOS. By introducing a caged coumarin fluorophore to the molecular architecture, self‐reporting fluorescence could be generated accompanied with APN‐mediated COS/H2S release, which achieved the visualization of H2S delivery in vitro and in vivo. This work not only offers a useful tool for studying the bioactivity of H2S on inflammation, but also provides new insights for developing novel therapies to cope with inflammation‐associated diseases.

ABSTRACTPolymer materials, commonly used and susceptible to damage from external forces and environmental factors, now have a new intelligent self‐healing variant inspired by living organisms. This material self‐repairs via dynamic covalent bonds and noncovalent interactions, mitigating microdamage risks and enhancing longevity. The self‐healing polyurethane urea based on disulfide bonds was prepared by reacting a prepolymer synthesized from lipoic acid (TA), triethylenetramine (TETA), and polytetrahydrofuran (PTMEG) with isocyanate. Subsequently, nickel powder modified with amino groups on the surface was prepared by the hydrolysis of tetraethyl orthosilicate (TEOS) and modification with 3‐aminopropyltriethoxysilane (APTES), and it was used as a magnetic and conductive filler added to the polyurethane urea to create magnetic self‐healing polyurethane urea composites (MPUU‐MNi). The material self‐repaired at 40◦C for 12 h after damage, with a self‐healing efficiency of 73%. The initial ultimate stress of MPUU‐MNi‐10 was 8.08 MPa, and after repair, the ultimate stress of MPUU‐MNi‐10 recovered to 5.89 MPa. It possesses good magnetic properties, mechanical properties, self‐healing performance, and magnetic driving performance. Engineers can acquire knowledge about the most recent developments in electromagnetic shielding, which they can creatively integrate into their projects. Delving into cutting‐edge materials and production methods could result in significant product innovation, enhancing their company's market edge.

ABSTRACTSuperelastic porous foam materials can change from soft to hard when subjected to external impacts. At the same time, they can disperse and absorb energy and delay the impact time, possessing extremely strong impact protection ability. To study the energy absorption characteristics of superelastic foam materials and the strengthening mechanism under high strain rates, compression experiments under different strain rates were carried out using an INSTRON 5966 small universal material testing machine and a Φ16 mm split Hopkinson pressure bar (SHPB) experimental system. The energy absorption efficiency, strain rate sensitivity index, and fracture morphology were analyzed. The results show that under quasi‐static compression, the stress–strain response of superelastic foam has two‐stage characteristics of a slow stress growth region and a rapid stress growth region, and it has an obvious strain rate strengthening effect. Under quasi‐static loading, the material has a relatively high energy absorption efficiency, and the strain rate has little influence on the maximum energy absorption efficiency of the material. Under dynamic loading, the superelastic foam material exhibits strain hardening at high strain rates. As the strain rate increases, its yield strength increases from 7 to 9.9 MPa. The fracture strength increases from 9.97 to 15.65 MPa. Under tensile loading, due to the presence of voids inside the material, the material directly fractures at the end of the elastic stage without a plastic deformation stage.
