Authors: Prada Rodríguez Eduin Alexander , Guzmán Pacheco Juan Felipe , Barchelot Aceros Laura Juliana 
Published: February 2024

Introduction: Childhood traumatic brain injury is one of the primary causes of dysfunctions in the child’s development and neurocognitive processes; it generates lesions at the brain level and in synaptic networks that interfere with functional processes; its deficiencies are heterogeneous; depending on the severity, history and location of the lesion, they may occur temporarily or permanently, even with significant sequelae. Objective: Establish the dysfunctional correlates associated with attention, memory, executive function, language and learning in childhood TBI.
Method: Scoping review; 44 selected articles extracted from information search conducted in databases SCOPUS, WEB OF SCIENCE, PSICODOC, EBSCO; PUBMED; SCIELO and REDALYC. Results: According to the findings, we determine the post-traumatic functional processes that are affected in memory systems, attentional system, language, executive function and learning. Conclusions: reaffirms that there is no functional damage standard for the category Cranioencephalic Trauma, because the deficiencies generated by the TBI are differentiated and systemic, reason why the scope of dysfunctional processes in the neurocognitive and learning domains is wide, with greater involvement in moderate and severe SCD.

AbstractAimThe occlusion of the teeth is affected due to the appearance of micro-cracks resulting from maximum stresses in the contact zones between the wire and the bracket under normal and tangential loading. The objective of this study is to evaluate the surface and volume constraints in the presence of bonding and partial sliding zones on the contact surface between wires and supports. Knowledge of these stress fields will make it possible to better limit the surfaces where most of the micro-cracks occur. Indeed, the evaluation of the stress will facilitate the modelling or application of established micro crack models on this subject, because the initiation of micro-cracks often appears on the contact surface or just below it.Materials and methodsIn this study, the two most common situations of contact between the wire and the bracket were studied; the first corresponds to the situation where the wire is positioned in the center of the support (classic friction), and the second corresponds to the situation where the inclined wire touches the ends of the supports (critical contact angle).The MATHCAD software was used to simulate the damage zones for normal loading in the two cases studied (classic friction, critical contact angle). We proposed a Hertzian loading for the first case and a linear loading for the second case. Also, the effect of the additional load during wire tightening applied by the orthodontist was studied.ResultsThe charge concentration is located above the contact zone, of the order of 0.3P0 (pressure per unit of arbitrary normal length), according to Mathcad simulation results. The adhesion zone/micro-slip zone contact generates the largest tangential load, which is directed towards the side experiencing the most stress. We also observed that the stick area shifts towards the recessed side when the additional load is applied. Additionally, comparing the configurations, the critical contact angle resulted in a higher maximum shear stress.

Published: February 2024

AbstractThe advent of small-scale robots holds immense potential for revolutionizing various industries, particularly in the domains of surgery and operations within confined spaces that are currently inaccessible to conventional tools. However, their tethered nature and dependence on external power sources impede their progress. To surmount these challenges, the integration of batteries into these diminutive robots emerges as a promising solution. This article explores the integration of batteries in small-scale robots, focusing on “hard” and “soft” approaches. The challenges of integrating rigid batteries into microrobots are discussed. Various battery materials suitable for microfabrication are explored, along with creating three-dimensional structures to optimize performance within limited space. The “soft” integration emphasizes the need for flexible and deformable battery technologies that seamlessly integrate with soft robotic systems. Challenges related to flexibility, stretchability, and biocompatibility are addressed. The concept of distributed and mobile energy units, where smaller batteries assemble into a larger power bank, is proposed for scalability and adaptability. Extracting energy from the environment, inspired by fuel cells, reduces reliance on traditional batteries. This article offers valuable insights into battery integration for small-scale robots, propelling advancements in autonomous and versatile systems. By overcoming current limitations, integrated batteries will unlock the full potential of small-scale robots across various industries.Graphical abstract
Correlation between Strain Rate and Seismicity in Different Tectonic Settings
Authors: Chen Yuxuan , Liu Mian 
Published: February 2024

Abstract
Geodetic strain rate characterizes present-day crustal deformation and therefore may be used as a spatial predictor for earthquakes. However, the reported correlation between strain rates and seismicity varies significantly in different places. Here, we systematically study the correlation between strain rate, seismicity, and seismic moment in six regions representing typical plate boundary zones, diffuse plate boundary regions, and continental interiors. We quantify the strain rate–seismicity correlation using a method similar to the Molchan error diagram and area skill scores. We find that the correlation between strain rate and seismicity varies with different tectonic settings that can be characterized by the mean strain rates. Strong correlations are found in typical plate boundary zones where strain rates are high and concentrated at major fault zones, whereas poor or no correlations are found in stable continental interiors with low strain rates. The correlation between strain rate and seismicity is also time dependent: It is stronger in seismically active periods but weaker during periods of relative quiescence. These temporal variations can be useful for hazard assessment.

Onion skin waste (OSW), the primary non-edible byproduct from onion processing, offers a renewable source of bioactive compounds. This study aims to valorize OSW through subcritical water extraction (SWE), aligning with circular economy and biorefinery principles. SWE was carried out at 145 °C, 50 bar and 50 min in a discontinuous reactor, producing a phenolic-rich extract (32 ± 3 mg/g), dominated by protocatechuic acid (20 ± 3 mg/g), quercetin-4´-O-glucoside (7.5 ± 0.2 mg/g), and quercetin (3.2 ± 0.6 mg/g). Additionally, it contains sugars (207 ± 20 mg sucrose-Eq/g), proteins (22.8 ± 1.6 mg BSA-Eq/g) and free amino acids (20.4 ± 1.2 mg arginine-Eq/g). Its phenolic richness determines its scavenging activity against ●NO and O2●- radicals, and its α-glucosidase and aldose-reductase inhibition without affecting α-amylase. Notably, the extract demonstrates significant α-glucosidase inhibition (IC50 = 76 ± 4 µg/mL), surpassing acarbose (IC50 = 129.5 ± 1.0 µg/mL), in both pure enzyme and cell culture tests without showing cytotoxicity on AGS, HepG2 and Caco-2 human cell lines. The extract’s bioactivity and nutritional content make it suitable for developing antioxidant and antidiabetic nutraceutical/food components, highlighting the SWE potential for OSW valorization without using organic solvents.
Geochronological and Geochemical Constraints on the Magmatic Evolution of the Dun Mountain Ophiolite Belt, New Zealand
Authors: Patias Daniel , Zhou Renjie , C. Aitchison Jonathan 
Published: February 2024

Abstract
New whole-rock major and trace element geochemical, zircon U-Pb geochronological, and Hf isotopic data from gabbroic rocks in New Zealand’s mid-Permian Dun Mountain ophiolite belt (DMO) provide insight into the evolution of subduction systems and early stages of intraoceanic arc development. Fe-oxide-bearing gabbros yielded high εHf(t) values (+10.3 to +13) and zircon U-Pb ages of 271.6 ± 0.6 Ma. In contrast, Fe-Ti-oxide-bearing gabbros of 268.1 ± 0.6 Ma show more enriched geochemical characteristics, including a wide range of εHf(t) values (+15.5 to +6.8). New findings strengthen the evolutionary model for the DMO and place constraints on its youngest known magmatic episode. We infer that late magmatism fingerprinted by these gabbros, including consistent negative Nb-Ta anomalies, reflects early stages of arc development and formation of island arc tholeiites on the DMO. Our model is consistent with other existing regional geochronological and geochemical data, implying that the DMO had an early stage of normal-mid-ocean ridge basalt crustal accretion followed by an influx of slab-derived components and maturity of the subducting system between ca. 271.6 and 268 Ma. These results extend our understanding of the evolution of distinct intraoceanic systems.

Volborthite and Its Composite with g-C3N4 for Oxytetracycline Removal: Their Adsorption and Photocatalysis Properties
Authors: Wee Wei Qing , Sim Lan Ching , Leong Kah Hon , Aziz Azrina Abdul 
Published: February 2024

Abstract
The photocatalytic-adsorption performance of the composites of volborthite (CuVA) and graphitic carbon nitride (g-C3N4) was studied in this work using oxytetracycline (OTC) as model pollutant under LED light irradiation. CuVA at different weight percentage (10, 30, 50), namely C10, C30 and C50 were loaded onto graphitic carbon nitride using wet chemical method. The physical, chemical and optical properties were evaluated via various analytical techniques. Through integrated adsorption-photocatalytic process, no significant photocatalytic reaction occurred in g-C3N4 and the composite even after 4 h of irradiation. The setup was modified such that each run was conducted in the presence and absence of light. Aside from photolysis and g-C3N4, all composites performed better under the presence of light in which CuVA improved the most from ~50% down to ~20% of initial concentration. CuVA performed almost identically (80% removal of OTC) under the presence of light irradiation at ambient temperature (22 °C) and in the dark at 32 °C, confirming that temperature was the contributing factor to the improvement instead of light. CuVA exhibited excellent adsorption capacity of 171 mg/g and adsorption rate of 90% towards the removal of highly concentrated OTC (100 mg/L) under optimized parameters of pH 5.0 and at 42 °C after 3 h of adsorption process. Life cycle assessment revealed that close to 50% of fresh 100 ppm OTC could be removed after 5 cycles without any desorption process.
Effect of Bio-Cellulose + Graphene Graft and Adipose Stem Cell on Axonal Regeneration in Experimental Sciatic Nerve Injury
Authors: Simsek Ismail , Cekic Efecan , Kirazli Ozlem , Unal Semra , Sahin Ali , Harman Ferhat 
Published: February 2024

Abstract
Background
Peripheral nervous system injuries cause catastrophic burdens due to the developing loss of function. The most limiting situation in the treatment of injuries is the low ability of the central nervous system to regenerate itself, and most of these damages are irreversible.
Aim
In this study; we aimed to elucidate the effect of in-vitro application of a scaffold of bio-cellulose and graphene oxide (BC + GO) mixture on the axonal healing potential after experimentally induced sciatic nerve injury in Wistar rats, alone or in combination with mesenchymal stem cells taken from rat viscera.
Materials and Methods
This experimental, prospective, randomized study was conducted on 27 male Wistar rats. They were evaluated into three groups, with nine in each group as Group 1 (autograft group), Group 2 (Graft group), and Group 3 (Graft + SC group). Sciatic nerve function index (SFI), EMG, and histo-pathology evaluation were performed at the end of the 8th week.
Results
There was no significant difference in SFI results within the three groups. In the case of EMG, there was a statistically significant difference among the first-month CMAP results of groups. First-month CMAP results of graft and graft + SC groups were significantly higher than the autograft group (p = 0.0046). During macroscopic observation, graft and graft + SC groups had abundant adhesions around the grafted site. On histo-morphology and immuno-histochemistry, regenerative findings were obtained in all three groups. The autograft group had no inflammatory response, while the graft group had the highest inflammation and degeneration. In the graft + SC group there were less inflammation than second one, which is a finding thought to be related with immunmodulatory effects of MSCs.
Conclusion
BS + GO graft might be useful in the first weeks of regeneration, but this wasn’t sustained in the long-term regenerative findings due to intense inflammatory response and loss of regenerated axonal structures.

Authors: Wang Hui , Lv Zhe , Cui Huanyong , Hou Rongguo , Liu Yuanjian 
Published: February 2024

Abstract
Abrasive waterjet peening is a favorable surface treatment method for improving the fatigue resistance of metal materials. An insight into the fatigue crack growth properties of AWJ peened specimens is meaningful for obtaining better strengthening performance. In present work, a numerical model of AWJ peening was established and experimentally validated for investigating the fatigue crack growth characteristics of Aluminum specimens. The effect of peening and loading conditions on the fatigue performance was also analyzed. The results indicated that the stress intensity factor at the peened region was enhanced and the crack propagation was significantly inhibited by the compressive residual stress. The influence of compressive residual stress on the effective stress factor range is greater under lower external load and higher loading ratio. The fatigue life for reaching the crack length of 40 mm is increased by 37%, 60% and 98% after peening by using the intensity of 0.6 mmA, 0.8 mmA and 1 mmA, respectively.
Half of the unprecedented global soybean production failure in 2012 is attributable to climate change.

Published: February 2024

Abstract
In 2012, soybean crops failed in the three largest producing regions due to spatially compound hot and dry weather across North and South America. Here, we present different impact storylines of the 2012 event by imposing the same seasonally evolving atmospheric circulation in a pre-industrial, present day (+1°C above pre-industrial), and future (+2°C above pre-industrial) climate. While the drought intensity is rather similar under different warming levels, our results show that anthropogenic warming strongly amplifies the impacts of such a large-scale circulation pattern on global soybean production, driven not only by warmer temperatures, but also by stronger heat-moisture interactions. We estimate that 51% (47-55%) of the global soybean production deficit in 2012 is attributable to climate change. Future warming (+2°C above pre-industrial) would further exacerbate production deficits by 58% (46-67%), compared to present-day 2012 conditions. This highlights the increasing intensity of global soybean production shocks with warming requiring urgent adaptation strategies.

Authors: Lu Xu , Zhao Yanzhong , Sun Shanhua , Li Hua , Ji Meng 
Published: February 2024

Abstract
Purpose: this work was to explore the diagnostic value and lesion evaluation value of magnetic resonance imaging (MRI) and X-ray in knee joint degenerative osteoarthropathy.
Methods: a total of 92 patients with knee degenerative osteoarthropathy who were admitted to our hospital from March 2021 to September 2022 were included in the study. They were randomly assigned into a control (Ctrl) group (n = 46) and an observation (Obs) group (n = 46) according to the random number table. X-ray films were taken in Ctrl group, and MRI images were taken in Obs group to compare their diagnostic accuracy and evaluation efficiency for arthropathy.
Results: in terms of osseous structural lesions, the detection rates of the two methods were not greatly different (P > 0.05). For meniscal cartilage and peripheral soft tissues, the detection rate of MRI was obviously superior to that of X-ray. The diagnostic sensitivity (95.55%) was obviously higher than that of X-ray (86.04%), and the diagnostic coincidence rate (93.47%) was obviously higher than that of X-ray (80.43%). For the first-stage joint lesions, the detection rates of MRI (55% and 11/20) were drastically superior to those of X-ray (35% and 7/20), while for the second-stage joint lesions, the detection rates of MRI (66.66% and 14/21) were higher than those of X-ray (45.4% and 10/21) (P< 0.05).
Conclusion: the diagnostic coincidence rate and detection rate of knee degenerative osteoarthropathy with MRI were superior to those with plain X-ray film, which is helpful for the early diagnosis of the disease and worthy of clinical promotion and adoption.
Rethinking hormonal contraception in breast cancer survivors

Published: February 2024

Abstract
Approximately 7% of women with breast cancer have less than 40 years at diagnosis. Despite of more aggressive characteristics of these tumors, earlier diagnosis and better treatments had increased the number of cancer survivors, and topics such as hormonal treatments, previously unimportant, have now to be discussed. As the concentration of the progestin in breast tissue of patients using Levonorgestrel intrauterine system is very low, there may be a safe alternative for this population. Here we show that low-dose Levonorgestrel did not increase proliferation of breast cells suggesting that, in well-defined situations, some exogenous hormones might be used in breast cancer survivors, thus improving their quality of life. We found in controlled in vitro assays that two mammary cell lines, MCF10A and MCF7, did not show cellular proliferation when exposed to the concentration of 0.01μM Levonorgestrel, even with positive controls of proliferation carried out with Estradiol showing significant difference in both strains. Our results demonstrate that this progestin alone does not seems to be the cause of breast cancer, and our assay may be a “restarting” point for more sophisticated in vitro models that can really explain what is safe, and what is not, for breast cancer survivors.
