RESUMO
The facile oxidation of Sn2+ to Sn4+ poses an inherent challenge that limits the efficiency and stability of tin-lead mixed (Sn-Pb) perovskite solar cells (PSCs) and all-perovskite tandem devices. In this work, we discover the sustainable redox reactions enabling self-healing Sn-Pb perovskites, where their intractable oxidation degradation can be recovered to their original state under light soaking. Quantitative and operando spectroscopies are used to investigate the redox chemistry, revealing that metallic Pb0 from the photolysis of perovskite reacts with Sn4+ to regenerate Pb2+ and Sn2+ spontaneously. Given the sluggish redox reaction kinetics, V3+ /V2+ ionic pair is designed as an effective redox shuttle to accelerate the recovery of Sn-Pb perovskites from oxidation. The target Sn-Pb PSCs enabled by V3+ /V2+ ionic pair deliver an improved power conversion efficiency (PCE) of 21.22 % and excellent device lifespan, retaining nearly 90 % of its initial PCE after maximum power point tracking under light for 1,000â hours.
RESUMO
The traditional knowledge about the therapeutic and nutritional value of fish has been unanimously recognized among the population since ancient times. So, thanks to the therapeutic virtues of these marine animals, it was possible to develop therapies for certain pathologies as well as the use of bioactive compounds as adjunctive therapies incorporated into the treatment regimen of patients. In the present study, stingray liver oil from wild species collected from the Romanian coast of the Black Sea was isolated and analyzed. Fatty acid analysis was performed by gas chromatography. The analysis of the distribution of fatty acids in the composition of stingray liver oil indicates a ratio of 2.83 of omega 3 fatty acids to omega 6, a ratio of 1.33 of polyunsaturated fatty acids to monounsaturated fatty acids, an iodine index of 111.85, and a total percentage of 68.98% of unsaturated fatty acids. Stingray liver oil was used to evaluate the healing action after preparing a fatty ointment. According to the experimental data, a complete regeneration capacity of the wounds was noted in 12 days without visible signs. Four emulgels with stingray liver oil were formulated and analyzed from a rheological and structural point of view in order to select the optimal composition, after which the anti-inflammatory effect on inflammation caused in laboratory rats was studied and an anti-inflammatory effect was found significant (a maximum inhibitory effect of 66.47% on the edemas induced by the 10% kaolin suspension and 65.64% on the edemas induced by the 6% dextran solution).

Ischaemia and reperfusion (I/R)-induced gastrointestinal disorders are caused by free radicals, resulting in organ damage and functional disarrangement. This study aimed to investigate the healing effects of hydroalcoholic extracts from the leaves of Eugenia punicifolia (Kunth) DC. (HEEP) in male and female Wistar rats with I/R-induced peptic injuries, and the role of antioxidants in improving this response. After I/R-induced gastric and duodenal injuries, male and female [intact (INT) and ovariectomized (OVZ)] rats were orally treated with HEEP for 6 days. Biochemical analysis was used to determine the catalase (CAT), superoxide dismutase (SOD), and myeloperoxidase (MPO) activities, as well as malondialdehyde and reduced glutathione levels, to measure the gastric and duodenal healing process. Six days of HEEP treatment significantly decreased the I/R-induced gastric [male (73.68%), INT (52.83%), and OVZ (43.13%)] and duodenal damage [male (57.03%), INT (56.04%), and OVZ (54.83%)] in all groups. In OVZ rats, the healing effect of HEEP occurred because of the increased activity of SOD (2x) and CAT (1.16x) in the gastric mucosa. In the duodenal mucosa of INT rats, the extract reduced MPO (20.83%) activity. The 6-day HEEP treatment improved the healing of I/R-induced peptic ulcer injury, with the system acting differently in males and females. The antioxidant system is an important component of the HEEP activity during post-I/R mucosal recovery. This result revealed the importance of antioxidant compounds in minimizing the severity of I/R-related events.

The purpose of the study is to determine therapeutic effectiveness of the pulsed high intensity optical irradiation device "Zarya" exemplified by treatment of model wounds in laboratory animals and to compare with traditional methods of wound treatment. The prototype of "Zarya" device was used whose operating principle was based on pulsed irradiation of affected areas with high intensity optical radiation in continuous spectrum generated by pulsed xenon lamp. The therapeutic effect of the "Zarya" device was compared with effectiveness of the certified medical ultraviolet irradiator based on low-pressure mercury lamp and also with known wound-healing and antibacterial medication Levomekol ointment. The mature male rats of Wistar line were used in the study. The animals were distributed to 4 groups: group 1 was irradiated by "Zarya" device, group 2 was irradiated by low-pressure mercury lamp, group 3 was treated with Levomekol ointment and group 4 was exposed to no exposure. The linear wound was modeled according to the standard method under ether anesthesia. The therapeutic procedures were applied daily during 7 days. The bactericidal effect was studied on the basis of smears from wound onto flora on the 2nd, 5th and 7th day. On the 8th day the animals were subjected to euthanasia. It was established that "Zarya" device application permits to reduce considerably both duration of therapeutic procedures and therapy course in general and also to achieve more pronounced bactericidal effect. The obtained data is supposed to be used for development of program of clinical trials.

Damage-repair is particularly important for the maintenance of the water-storing abilities of succulent plants such as cacti. Comparative morphological, anatomical, and biomechanical analyses of self-repair were performed on artificially wounded branches of Opuntia ficus-indica and Cylindropuntia bigelovii. Macroscopic observations, contrast staining, and lignin-proof staining were used to investigate morphological and anatomical responses after wounding at various time intervals. Two-point bending tests were repeatedly performed on the same branches under unwounded, freshly wounded, and healed conditions by using customized 3D-printed clamping jaws. Morphologically, both species showed a rolling-in of the wound edges, but no mucilage discharge. Anatomically, ligno-suberized peridermal layers developed that covered the wound region, and new parenchyma cells formed, especially in O. ficus-indica. In all samples, the wounding effect directly after damage caused a decrease between 18% and 37% in all the tested mechanical parameters, whereas a positive healing effect after 21 days was only found for C. bigelovii. Based on our data, we hypothesize a high selection pressure on the restoration of structural integrity in the wound area, with a focus on the development of efficient water-retaining mechanisms, whereas the concept of "sufficient is good enough" seems to apply for the restoration of the mechanical properties.

BACKGROUND: Despite the achievements in modern medicine, there is no effective natural treatment of second-degree burns till now. Therefore, the purpose of this study was to assess the wound-healing efficiency of three extracted oils, from the prickly pear, pumpkin and linseed on partial-thickness burns induced by fractional CO2 laser (an innovative up-to-date technique) in rats. MATERIALS AND METHODS: Thirty rats completing partial-thickness burns by fractional CO2 laser were randomly divided into five groups. The burns were measured, photographed, and topically treated daily with saline solution, "CYTOL BASIC," pumpkin-, linseed-, and prickly pear-extracted oils (0.52 µL/mm(2) of oil) until day 7. The response to treatments was assessed by macroscopic, histologic, and biochemical parameters. RESULTS: Due to their chemical composition, the extracted oils showed significant improvements over the control and reference groups during the trial for both general wound appearance and crusting. On day 7, the prickly pear, linseed, and pumpkin oils showed a significant decrease in the healing time (0 cm(2), 0.15 cm(2), and 0.18 cm(2), respectively) when compared to the control and reference groups (1.49 cm(2) and 0.85 cm(2)). Histologic assessment of the prickly pear oil-treated group revealed good healing proprieties compared with the other groups. The collagen content in prickly pear oil-treated group was found to be significantly greater (270.67 ± 7.48) than that in all other groups. CONCLUSIONS: Our experiment has shown, for the first time, a scientific evidence of the efficiency of extracted oils of prickly pear, pumpkin, and linseed on partial-thickness burns.

The simple message of this paper is that it is the high time to reevaluate the strategies and optimize the efforts for investigation of thermal (spa) waters. Several articles trying to clear mode of action of medicinal waters have been published up to now. Almost all studies apply the unproven hypothesis, namely the inorganic ingredients are in close connection with healing effects of bathing. Change of paradigm would be highly necessary in this field taking into consideration the presence of several biologically active organic substances in these waters. A successful design for experimental mechanistic studies is approved.

The conservative single-layered wound dressing system is decomposed when mixed in polyvinyl alcohol (PVA) solution, which means it cannot be used with a temperature-sensitive drug. The goal of this investigation was to make an amniotic membrane extract (AME)-loaded double-layered wound dressing with an improved healing result compared to the conservative single-layered wound dressing systems. The double-layered wound dressing was developed with PVA/sodium alginate using a freeze-melting technique; one layer was PVA layer and the other was the drug-loaded sodium alginate layer. Its gel properties were assessed compared to single-layered wound dressings. Moreover, in vivo wound-healing effects and histopathology were calculated compared to commercial products. The double-layered wound dressing gave a similar gel fraction and Young's module as single-layered wound bandages developed with only PVA, and a similar inflammation ability and WVTR as single-layered wound dressings developed with PVA and sodium alginate. Our data indicate that these double-layered wound bandages were just as swellable, but more elastic and stronger than single-layered wound dressings comprised of the same polymers and quantities, possibly giving an acceptable level of moisture and accumulation of exudates in the wound zone. Compared to the commercial product, the double-layered wound dressing comprising 6.7% PVA, 0.5% sodium alginate and 0.01% AME significantly enhanced the wound-healing effect in the wound-healing test. Histological investigations showed that superior full-thickness wound-healing effects compared to the commercial product. Therefore, the double-layered wound dressing would be an outstanding wound-dressing system with improved wound healing and good gel property.

The pursuit of sub-1-nm field-effect transistor (FET) channels within 3D semiconducting crystals faces challenges due to diminished gate electrostatics and increased charge carrier scattering. 2D semiconductors, exemplified by transition metal dichalcogenides, provide a promising alternative. However, the non-idealities, such as excess low-frequency noise (LFN) in 2D FETs, present substantial hurdles to their realization and commercialization. In this study, ideal LFN characteristics in monolayer MoS2 FETs are attained by engineering the metal-2D semiconductor contact and the subgap density of states (DOS). By probing non-ideal contact resistance effects using CuS and Au electrodes, it is uncovered that excess contact noise in the high drain current (ID) region can be substantially reduced by forming a van der Waals junction with CuS electrodes. Furthermore, thermal annealing effectively mitigates sulfur vacancy-induced subgap density of states (DOS), diminishing excess noise in the low ID region. Through meticulous optimization of metal-2D semiconductor contacts and subgap DOS, alignment of 1/f noise with the pure carrier number fluctuation model is achieved, ultimately achieving the sought-after ideal LFN behavior in monolayer MoS2 FETs. This study underscores the necessity of refining excess noise, heralding improved performance and reliability of 2D electronic devices.
RESUMO
Ultra-high temperature ceramics (UHTCs) have been widely applied in many fields. In order to enhance the comprehensive properties of TaB2-based UHTCs, the first collaborative use of fine TaC particles and dispersed multi-walled carbon nanotubes (MWCNTs) was employed via spark plasma sintering (SPS) at 1700 °C. The derived UHTCs exhibited an average grain size of 1.3 µm, a relative density of 98.6%, an elastic modulus of 386.3 GPa, and a nano hardness of 21.7 GPa, leading to a greatly improved oxidation resistance with a lower linear ablation rate at -3.3 × 10-2 µm/s, and a markedly reinforced ablation resistance with mass ablation rate of -1.3 × 10-3 mg/(s·cm2). The enhanced ablation resistance was attributable to the physical pinning effect, sealing effect and self-healing effect. Thus, this study provides a potential strategy for preparation of UHTCs with bettered ablation resistance and physical properties.
RESUMO
The objective of this study was to formulate dip coatings, incorporating casein, NaOH, and nanocrystalline hydroxyapatite (nanoHAp), with self-healing properties for application on ZnMg3.2 wt.% alloy in the field of biomedical applications. This study hypothesizes that the self-healing mechanism within the layer will impede substrate degradation by progressively filling defects where chlorides from simulated body fluids intervene. Furthermore, it aims to mitigate potential damage effects during the implantation process by the layer's self-healing capabilities. The research focused on the dip-coating process parameters and chemical composition of baths for producing casein coatings on Zn alloy surfaces. This study investigated the impact of casein and NaOH concentration, along with the immersion time of ZnMg3.2 wt.% samples in the coating bath, on the self-healing capability of the coating under simulated human body fluid conditions (Ringer's solution, temperature: 37 °C). Effective technology was developed by selecting specific chemical compositions and immersion times in the coating bath, enhancing the self-healing progress against coating damage in Ringer's solution at 37 °C. The most significant self-healing effect was observed when the ZnMg3.2 wt.% substrate underwent a 1 h immersion in a coating bath containing 2 g of casein, 4 g of NaOH, and 0.1 g of nanoHAp powder. Electrochemical tests were instrumental in determining the optimal casein concentration and immersion time of the Zn alloy in the coating bath.
RESUMO
Although the effectiveness of urban forest therapy has been studied and proven, most people are not well aware of the positive healing effects of urban forests that are easily accessible in daily life compared to the known healing effect of forests located outside urban areas. In addition, there has been a study on the analysis of urban forest healing program needs in the general population, but there is a lack of evidence on the expected values and needs of urban forest healing for people with diseases. Therefore, this pilot survey aimed to investigate the expected values, needs, and preferred components of urban forest healing programs in urban forest visitors with disease via an online user survey and see if there were any differences in the purpose of the urban forest visits and expected values of urban forest healing depending on the type of disease. The survey was conducted on 294 urban forest visitors with diseases. About 79% of respondents agreed with the healing effects of urban forest, however most respondents expected healing effects on mental health rather than on physical health ("mood change" was the highest with score of 4.43/5, followed by "reliving stress" (4.35/5) and "mental and physical stability" (4.31/5)). In addition, more than 82.0% of respondents agreed to participate in the program if a healing program for disease was developed. The results of the current pilot survey indicate that the purpose of the urban forest visits and expected values of urban forest healing were largely not different by the type of disease, and people with disease had a relatively lower awareness and lower expected values of urban forest healing effects on physical health, but high demand for the program. Urban forest therapy programs should be developed based on the specific clinical characteristics of the disease to maximize the effectiveness of the program. Additionally, policies should be implemented to promote the beneficial effects of urban forest healing not only for mental health but also for physical health.

From the perspective of emotional preference, studies have been conducted about landscape healing for subhealth people in the National High-Tech Zone (the study area). Combined with a preliminary practice investigation, Unity 2019 was used to make a digital roaming landscape, and 91 subjects with a history of mental subhealth diseases were randomly invited to participate in the immersive experimentation of the Human-Machine Environment Synchronisation (ErgoLAB) platform. After the experiment, the subjects were invited to fill in a Likert scale as the control group. The interest preference, emotion fluctuation, and healing effect of landscape colour were verified. The results show that: (1) The variation trend of interest reflected the concentration of interest in landscape, and the order of degree of interest, ranging from high to low, went Green > Yellow > Blue > Red > Orange > Purple > Cyan. (2) The subjects' interest in landscape colour was correlated with the arousal of positive emotions. The correlation between interest in landscape colour and positive emotions, from high to low, went Blue > Green > Yellow, while the correlation between red, cyan, orange, and purple was not significant. (3) The mean skin conductance (SC) fluctuation variance of subjects was 5.594%, which confirmed that the healing effect of digital roaming landscape scenes was significant under the state of low arousal. According to the Likert scale data, subjects' scores of the healing effect of landscapes, from high to low, went as follows: Green > Yellow > Red > Blue > Cyan > Orange > Purple. The results provide a new method for demonstrating the logical relationship between the digital landscape interest experience-emotional awakening-healing effect and providing a theoretical method and construction scheme for landscape colour configuration in the implementation of landscape healing projects.

Although many studies have suggested that nature-based activities have a healing effect on human beings, there is little research on the underlying mechanism. This study investigated the role of nature connectedness in the relationship between the perception of nature and individuals' physical and psychological health. We recruited essential workers who participated in disease prevention and control during the COVID-19 pandemic and their family members as the subjects for this study. The stress levels experienced by this group made them an ideal sample. The results of a survey-based study showed that nature-based activities had a positive effect on alleviating state anxiety levels. The results also showed that nature-based activities affected perceived restoration via the feeling of nature connectedness. This study examined the healing effect of nature-based activities that stimulate the five senses and nature connectedness and explored the potential of nature-based treatments for people experiencing high levels of stress.

Impacted by the COVID-19 epidemic, the human sub-health in national high-tech zones (hereinafter referred to as high-tech zones) has become more prominent. It is critical for the mental sub-health group in the high-tech zone to relieve the anxiety and tension caused by the pressure of life and work. This paper uses SketchUp virtual engine (Unity 2019) software, and 3D roaming technology to carry out the ecological landscape transformation design of the Baotzixi ecological corridor in the East Lake High-tech Zone, to construct a 3D roaming landscape scene and measure its therapeutic effect by inviting subjects to participate in an interactive experience experiment on the ErgoLAB platform. The results illustrate that: (1) the thermogram trend shows that the more attractive the 3D roaming landscape scene is, the stronger the subjects' interest is; (2) the participants have a positive emotional arousal state in the immersive experience of the 3D roaming landscape scene after the modification design; and (3) the mean skin conductance (SC) fluctuation variance of the subjects is 5.819%, indicating that the healing effect is significant in the state of positive emotional arousal. The research results show that there is a connection between the subjects and the 3D roaming landscape scene after the transformation design of "high interest, emotional arousal and significant healing".

The civil research community has been attracted to self-healing bacterial-based concrete as a potential solution in the economy 4.0 era. This concept provides more sustainable material with a longer lifetime due to the reduction of crack appearance and the need for anthropogenic impact. Regardless of the achievements in this field, the gap in the understanding of the importance of the bacterial role in self-healing concrete remains. Therefore, understanding the bacterial life cycle in the self-healing effect of cement-based materials and selecting the most important relationship between bacterial contribution, self-healing effect, and material characteristics through the process of microbiologically (bacterially) induced carbonate precipitation is just the initial phase for potential applications in real environmental conditions. The concept of this study offers the possibility to recognize the importance of the bacterial life cycle in terms of application in extreme conditions of cement-based materials and maintaining bacterial roles during the self-healing effect.
RESUMO
Studies have shown that 0.05 mL/kg of drug No. 1 as 1:15 dilution with sterile saline solution has anti-inflammatory, wound-healing, and angioprotective effects if instilled in both eyes of rabbits twice a day for 30 days after an alkaline burn. A stimulation of reparative processes in the cornea was observed with the test dose of drug No. 1. This was manifested by accelerating the recovery of defects in the anterior epithelium and stroma, reducing the frequency of formation of deep defects and the severity of inflammatory reaction and vascularization, and inhibiting the formation of turbidity of its lower intensity and area. A tendency to restore laminarity of the stroma was determined by the action of drug No. 1 throughout the observation period. This contributed to a decrease in the degree of vascularization and prevented ulceration and perforation of the cornea. By the end of experiment, a restoration of strong epithelial-stromal relationships in the experimental group, compared to the control group, was observed due to formation of normal architectonics of fibrous components of intercellular substance. A more pronounced proliferative activity, with an increase in the layering of limbal epithelial cells, was noted in the limbal zone of the cornea in the experimental group rabbits compared to the control group.

Reversible dynamic bonds are able to crack and recombine upon external stimuli, which endow polymers with exceptional self-healing, reprocessing, and reversible deformation ability. In this paper, we integrated the metal coordination bonds into shape memory poly(aryl ether ketone) (PAEK) to fabricate smart materials with multifunctionalities. Through tuning the metal ion content and species, the enhancement of shape memory behaviors was achieved, including the high recovery ratio (over 98%) and fixity ratio (over 98%), which was closely related to the synergic effect of the intrinsic motion ability of PAEK matrix and the cracking-recombination of coordination bonds. Besides, through the combination of the components with different Cu2+ contents, in addition to the components with Fe2+ coordination bonds, we fabricated the gradient shape memory structures with controllable shape memory and recovery behaviors. The manipulation of gradient coordination bonds resulted in different shape recovery speeds and directions. Furthermore, due to the dynamic cracking-recombination of coordination bonds, the metal-coordinated PAEK material exhibited the great self-healing and reprocessing performances, which were significant for largely extending its application range.
RESUMO
It was shown that in the model of dry eye syndrome (DES) in rabbits, if drug No. 5 was instilled in both eyes of animals at a dose of 0.05 mL/kg in 1:15 dilution with sterile saline solution twice a day for 30 days, then it had a strong anti-inflammatory, wound-healing, and angioprotective effects. This positively affected the course of reparative process in the conjunctiva and cornea complicated by nonclosing of the eyelids. It was also found that drug No. 5 in the tested dose promoted the stimulation of reparative processes in the conjunctiva and cornea, clinically manifesting itself in accelerating the recovery of defects in the anterior epithelium and corneal stroma, and in reducing both frequency of formation of deep corneal defects and severity of inflammatory response and vascularization. There was a slowdown in the formation of corneal opacities, a decrease in the amount and appearance of a more liquid mucous discharge of the conjunctiva compared to the control. It was also demonstrated in the stated model of DES that drug No. 5 in the test dose had a pronounced pharmacological effect, contributing to a faster recovery of damage to the superficial epithelium and stroma of the cornea, anterior and posterior chambers of the eye, the vascular membrane and retina as well as goblet cells of the conjunctiva.

BACKGROUND: Cerebral infarction patients need to be bedridden for long periods of time often resulting in pressure injuries, which may represent a serious threat to patients' life and health. An effective nursing program should be adopted for timely intervention in patients with pressure wounds. AIM: To explore the value of nursing services based on a multidisciplinary collaborative treatment team in patients with pressure injury wounds following cerebral infarction. METHODS: Patients with cerebral infarction pressure injury wounds in our hospital from December 2016 to January 2021 were selected and divided into one study group and one control group based on the simple random number table method. The control group was treated with conventional nursing care (CNC), and the study group was treated with care services based on multidisciplinary collaborative care (MDCC). The Pressure Ulcer Scale for Healing (PUSH), healing effect, Self-Perceived Burden Score (SPBS), and satisfaction with the intervention were calculated before and after 2 and 4 wk of intervention in both groups. RESULTS: Sixty-two patients were enrolled, and 31 patients were assigned to each group. The results of the interventions were as follows: (1) There was no significant difference between the PUSH scores of the MDCC group (11.19 ± 2.46) and CNC group (12.01 ± 2.79) before the intervention (P > 0.05), and the PUSH scores were lower after 2 and 4 wk of intervention in the MDCC group (6.63 ± 1.97 and 3.11 ± 1.04) than in the CNC group (8.78 ± 2.13 and 4.96 ± 1.35 points) (P < 0.05); (2) The rate of wound healing in the MDCC group (96.77%) was higher than that in the CNC group (80.65%) (P < 0.05); (3) There was no significant difference between the SPBS scores of emotional factors (21.15 ± 3.11), economic factors (9.88 ± 2.15), and physical factors (8.19 ± 2.23) in the two groups before the intervention. The scores of emotional factors (13.51 ± 1.88), economic factors (6.38 ± 1.44), and physical factors (5.37 ± 1.08) were lower in the MDCC group than in the CNC group (16.89 ± 2.05, 7.99 ± 1.68 and 7.06 ± 1.19) after 4 wk of intervention (P < 0.05); and (4) Satisfaction with the intervention was higher in the MDCC group (93.55%) than in the CNC group (74.19%) (P < 0.05). CONCLUSION: Interventions for patients with cerebral infarction pressure wounds based on an MDCC treatment team can effectively reduce patients' self-perceived burden, improve pressure wound conditions, facilitate wound healing, and increase patient satisfaction with the intervention.
