Autogenous lamellar corneal grafting in dogs
Authors: Brightman Alan H. , McLaughlin Susan A. , Brogdon J. Daniel
Published: February 2025

Lamellar, autogenous, corneal grafts were performed on 9 clinically normal dogs (1 eye in each of 2 dogs and both eyes in each of 7 dogs) and 7 dogs with corneal disease (1 eye in each dog). Nylon, polyglycolic acid, polyglactin 910, and polydioxanone suture materials were used in 8-0 to 10-0 sizes. The eyes of the normal dogs were examined weekly for up to 16 weeks; corneal endothelium was reestablished in all eyes by 6 weeks after surgery. The eyes of the dogs with corneal disease were reexamined periodically for up to 9 months.

Twenty-two of 23 (95.7%) grafts were considered successful in that they were translucent, and the dogs were able to see after surgery. The suture materials that caused the least tissue reaction were nylon and polyglactin 910.

This procedure is indicated for chronic descemetoceles and other perforating corneal disease. It has the advantage of rapidly resolving severe corneal disease, with a high degree of success.
Epidemiologic investigation and control of an epizootic of anaplasmosis in cattle in winter
Authors: Smith R. D. , Hungerford L. L. , Armstrong C. T.
Published: February 2025

An epizootic of anaplasmosis affecting 18 of 90 beef cows in winter on a western Illinois ranch was investigated to determine the probable source and mode of transmission. The cause of the epizootic was Anaplasma caudatum. Cows were classified as sick, convalescent, or carrier on the basis of blood smear, complement fixation, or modified rapid card agglutination test results. Patterns of movement did not suggest a common exposure prior to assembly of cattle at the affected ranch. The combination of clinical stages and temporal pattern of the epizootic was compatible with exposure on one or more occasions after arrival of cattle on the ranch, most likely during herd vaccination or ear tagging. A serologic testing and treatment program was initiated to rid the herd of infection. Seventeen surviving cows were treated 3 times with 20 mg of oxytetracycline/kg, im, at 5-day intervals. At the end of the 6-month follow-up period, 1 of 17 cows was still serologically positive and was treated with a second regimen of oxytetracycline. We believe that eradication of A caudatum was successful, because no clinical cases of anaplasmosis have been reported on the ranch during the last 3 vector seasons.

Published: February 2025

Cattle that had recovered from clinical oak bud toxicosis (as assessed by normal bun and serum creatinine values and good appetite) performed better than did clinically normal herdmates when weight gain and feed efficiency were compared. Both groups had a rate of weight gain (oak bud-exposed cattle, 1.76 kg/steer/d; control cattle, 1.57 kg/steer/d) that exceeded the feedlot mean value (approximately 1.4 kg/d) for cattle (of similar starting weight and diet) that had zeranol implants, and the difference was significant (P < 0.005) for both groups. The difference in weight gain performance of oak bud-exposed cattle, compared with control cattle, was not highly significant; however, the improved feed efficiency was significantly (P < 0.05) better than that in controls (2.57 kg of feed/kg of weight gain vs 3 kg of feed/kg of weight gain). On the basis of accepted criteria (increased rate of weight gain and efficiency of feed conversion), the group of oak bud-exposed cattle of this study had compensatory weight gain. Thus, cattle with good evidence of clinical recovery from oak bud toxicosis can be expected to perform in the feedlot at least as well as cattle not exposed to oak bud toxicosis, and may have compensatory weight gain.
Evaluation of practical dry dog foods suitable for all life stages
Authors: Czarnecki-Maulden Gail L. , Deming Judith G. , Izquierdo Julia V.
Published: February 2025

We evaluated the nutritional adequacy of 2 dry-type commercially prepared dog diets by use of a gestation/lactation/growth protocol outlined by the Association of American Feed Control Officials. Both diets were formulated to contain minimal concentrations of nutrients, compared with canine nutrient requirements listed in the 1974 or 1985 National Research Council publications. Although there were no significant differences in the performance of dogs fed either diet, only one of the diets (diet 2) passed the complete life-stage protocol test. The nutritional profile of diet 1 was only sufficient to support a claim of complete and balanced nutrition for adult maintenance. Any commercial dry dog food meeting the nutrient levels in diet 2, and of similar nutrient bioavailability, should also pass an Association of American Feed Control Officials complete life-stage protocol test.

Authors: Sischo William M. , Ihrke Peter J. , Franti Charles E.
Published: February 2025

We investigated the regional distributions of the most commonly diagnosed shin diseases in dogs from 17 North American veterinary teaching hospitals. Between January 1983 and December 1983, 11,436 diagnoses of shin disease were made. The 10 most common diagnoses were fleabite allergic dermatitis, shin cancer, pyoderma, seborrhea, allergy, demodectic acariasis (demodicosis), sarcoptic acariasis, immune-mediated skin disease, endocrine related skin disease, and acral lick dermatitis. Regional differences in the frequency of skin diseases were apparent. The northeast region had high frequencies of fleabite allergic dermatitis, allergy, and immune-mediated disease, and a low frequency of seborrhea. The midwest had a high frequency of seborrhea, and low frequencies of demodectic acariasis and allergy. In the plains region, low frequencies of jleabite allergic dermatitis, pyoderma, seborrhea, allergy, and demodectic acariasis were detected. In the west, the frequencies of fleabite allergic dermatitis, skin cancer, pyoderma, seborrhea, and acral lick dermatitis were high, whereas few dogs had allergic disease and sarcoptic acariasis. The southwest had high frequencies of fleabite allergic dermatitis and demodectic and sarcoptic acariasis. Fleabite allergic dermatitis, pyoderma, and demodectic and sarcoptic acariasis were frequently diagnosed in the southeast, but the number of dogs with seborrhea was low.
Class-specific and polyvalent enzyme-linked immunosorbent assays for detection of antibodies to Borrelia burgdorferi in equids
Authors: Magnarelli Louis A. , Anderson John F.
Published: February 2025

Class-specific and polyvalent elisa were developed to detect IgM antibody or total immunoglobulins to Borrelia burgdorferi in equine sera. Analyses of 122 serum specimens, collected during 1985 from horses and ponies in tick-infested areas of Connecticut, revealed IgM antibody in 41 (34%) samples; titration end points ranged from 1:160 to 1:2,560. In polyvalent elisa, 73 (16%) of 454 serum specimens contained IgM and/or IgC antibody. Seropositivity was highest (32%) for blood samples collected during May. Both elisa procedures had comparable sensitivities.
Methods of stimulating acupuncture points for treatment of chronic back pain in horses
Authors: Klide Alan M. , Martin Benson B.
Published: February 2025

Horses with chronic back pain of 2 to 108 months' duration were treated using acupuncture (n = 15), laser acupuncture (n = 15), or injection acupuncture (n = 15). Horses were treated once a week for 8 treatments (mean) with needle acupuncture, 11 treatments with laser acupuncture, or 9 treatments with injection acupuncture. After treatment, 37 horses had alleviation of clinical signs of pain and could train and compete: 13 horses treated with needle acupuncture; 11 horses treated with laser acupuncture; and 13 horses treated with injection acupuncture. Seemingly, the 3 types of acupuncture were equally useful for treating horses with chronic bach pain.
Isolation and identification of Chlamydia psittaci from pet birds
Authors: Pearson J. E. , Gustafson G. A. , Senne D. A. , Peterson L. A.
Published: February 2025

Culturing of Chlamydia psittaci from pet birds requires the inoculation of a susceptible living host system with suspensions of various tissues from dead birds or with tracheal and/or cloacal swabs and fresh feces from live birds. Cell cultures have been used as the host system. The most commonly used cell cultures for isolation of C psittaci from pet birds are McCoy and mouse L cells. The sensitivity and specificity of cell culture equals or surpasses embryonating chicken eggs and mice, and results can be obtained in <7 days. To obtain satisfactory results, the inoculum must be centrifuged onto the cell cultures at 37 C, and the cells must be treated with a metabolic inhibitor such as colchicine or cycloheximide. Chlamydia psittaci can be detected in infected cells by use of fluorescent antibody, Giemsa, or Gimenez staining.

Published: February 2025

One hundred eighty-five dogs with histologically confirmed, measurable malignant tumors were used in a prospective study to determine the response to 2 doses of the anthracycline antitumor antibiotic, doxorubicin. Eighty-three dogs had been refractory to one or more previous treatment modalities (surgery, n = 54; chemotherapy, n = 22; radiation, n = 10; hyperthermia, n = 1; biological response modifier, n = 1). The extent of neoplastic disease was determined immediately prior to and 3 weeks after 2 doses of doxorubicin were administered (30 mg/m2 of body surface area, iv) 21 days apart.

Eighty-four percent (n = 157) of the dogs received 2 doses of doxorubicin and were evaluated. Of the 28 dogs ruled ineligible, 4 had serious side effects to the first dose of doxorubicin, and 24 others acquired complications resulting from their malignant tumors. A partial or complete remission was obtained in 41% (64/157) of all evaluable dogs: 26% (11/43) of the dogs with carcinoma, 67% (42/63) of the dogs with lymphoma, and 22% (11/51) of the dogs with sarcoma. Tumors in which there was at least a 50% volume reduction (partial or complete remission) included malignant lymphoma (42/63), fibrosarcoma (1/14), solid follicular thyroid carcinoma (3/13), mammary adenocarcinoma (2/8), hemangiosarcoma (2/8), osteosarcoma (1/6), circumanal carcinoma (3/5), synovial cell sarcoma (2/3), undifferentiated sarcoma (2/3), nasal adenocarcinoma (1/2), liposarcoma (1/2), Infiltrating lipoma (1/1), malignant melanoma (1/1), sclerosing mesothelioma (1/1), and neurofibrosarcoma (1/2).

Our results indicated that 2 doses of doxorubicin resulted in a measurable regression in the size of various malignant tumors in dogs.
Lack of evidence of transmission of bovine leukemia virus by rectal palpation of dairy cows
Authors: Lassauzet Marie-Liesse G. , Thurmond Mark C. , Walton Ralph W.
Published: February 2025

A study was undertaken in a California dairy to estimate the risk of transmission of bovine leukemia virus associated with rectal palpation of cows. The probability of seroconversion within 3 months after rectal palpation was examined as a function of the prevalence of infection in cows at the time of palpation. It was hypothesized that the probability of seroconversion within 3 months after palpation would be higher for cows in a group with high prevalence of infection than for cows in a group with low prevalence. The probability of seroconversion after rectal palpation was equal to 0.034, and results of logistic regression, using data from 1,116 noninjected and 1,047 injected cows, did not indicate any significant association between probability of seroconversion after rectal palpation and prevalence of injection (P = 0.189). Results of this study suggest that risk of bovine leukemia virus transmission by rectal palpation typically used in reproductive tract examination of cows either does not occur or is uncommon.
Using the Choquet integral for the determination of the anxiety degree
Authors: Chiţescu Ion , Manea Mădălina Giurgescu , Paraschiv Titi
Published: February 2025

One considers a group S of subjects and one uses the measured values of EEG waves and the levels of anxiety given by the psychologists for the members of S in order to construct a monotone measure µ. This measure µ is such that the levels of anxiety of the members of S are Choquet integrals with respect to µ. One infers that this is true for any other subject. This inference is validated by comparing the values obtained via the above mentioned method with the results given by the psychologists for another group of subjects S’. We think that this procedure is completely new for the computation of the anxiety degree.

The theta method is defined such that, in general case, it is implicit in both drift coefficient and neutral term. Sufficient conditions of the a.s. exponential stability of the θ-Euler-Maruyama method, including the linear growth condition on the drift coefficient of the equation, are revealed.

Published: February 2025

We introduce a connectedness in the digital space ℤ3 induced by a quaternary relation. Using this connectedness, we prove a digital 3D Jordan-Brouwer separation theorem for boundary surfaces of the digital polyhedra that may be face-to-face tiled with certain digital tetrahedra in ℤ3. An advantage of the digital Jordan surfaces obtained over those given by the Khalimsky topology is that the former may bend at the acute dihedral angle

Published: February 2025

Monastic education has a rich history rooted in discipline, community, intellectual pursuits and spirituality. Every year, parents all over South Africa are posed with the question of selecting a school for their children. This article aims to evaluate the role of monastic educational principles in shaping the educational experiences within monastic schools. In a modern context, these principles continue to play a significant role in the development of students within monastic schools nurturing well-rounded learners for life after school. This paper adopted a qualitative approach and included a total of 12 participants from four schools. The principals and two department heads from each school were chosen to provide a thorough evaluation of the role that monastic educational principles play in education in monastic schools. By examining and exploring the ways in which monastic educational principles are implemented, this article highlights the enduring influence of monastic traditions in education and underscores their relevance in preparing young men for a well-rounded and meaningful life. This article was authored to assist with the understanding of the value that these kinds of schools have in our educational system. It is evident from the findings and affirmations of the participants that there are both advantages and disadvantages when evaluating the role monastic educational principles play in education in monastic schools. The recommendations of the study include that there should be a strong emphasis by teachers, department heads and principals on the application of monastic principles as there is a direct link to strong academic performance.

The study aimed to determine the effect of water and feeding frequency on feed intake, weight gain, milk production, and composition of Azikheli buffalo in climate conditions of Northern Pakistan. Forty multiparous Azikheli buffaloes with similar live body weight, third lactation stage were selected and randomly divided into four groups with ten replicates in each group: GP-1 (water and feed once daily), GP-2 (water and feed twice daily), GP-3 (water-adlib + feed thrice daily), and GP-4 (water-adlib + adlib feed). The basic feed consisted of maize fodder, wild grass, wheat straw. The concentrate feed (2 kg) was supplemented to all groups. Individual access to watering and feed were provided for each animal. The feed samples were analyzed for their chemical composition, and digestibility. The data mean was calculated using repeated-measures ANOVA. Different water frequencies have a statistically significant effect on water intake, dry matter intake, milk production, and milk composition. The average daily water intake in GP1, GP2, GP3, and GP4 was 28.00, 44.00, 56.00 and 67.30 liters, respectively. The average intake of dry matter was 10.20, 11.15, 12.40 and 12.97 kg, respectively. Daily milk yield was 6.90, 7.44, 8.10 and 8.38 liters, respectively. Dry matter intake and milk production were significantly influenced by the frequency of water consumption and nutritional balance. A balanced diet and unrestricted access to water increased milk production by 1.90 liters per animal per day. It was determined that a balanced diet and ad libitum water consumption increased the feed intake and milk production in Azikheli buffaloes and could yield higher profitability of dairy farms.

Published: February 2025

This study investigated the impact of adding lead (Pb) and molybdenum disulfide (MoS2) to copper–graphite (Cu–Gr) composites used in electric motors. The composites were produced by mechanical alloying (MA). The mixture was then poured and compressed with varying amounts of Pb and MoS2. Differential thermal analysis was used to determine the sintering temperature of the samples. Further tests were conducted to assess the samples’ wear resistance, density, hardness, and porosity. The effects of the additives of these factors were examined, and the output current of the samples was measured. Scanning electron microscopy was also used to analyze the morphology of the Gr plates coated with Cu, Pb, and MoS2. The results indicated that adding Pb and MoS2 increased the density of the sintered samples and their Vickers hardness. Meanwhile, porosity decreased with increased concentrations of Pb and MoS2. Additionally, MoS2 was found to improve wear resistance via a pin-on-disk test.

Authors: Matahela Vhothusa Edward , Samie Nathma , van Rensburg Gisela Hildegard
Published: February 2025

Background: The escalating effects of climate change pose grave threats to ecosystems and human health worldwide, intensifying inequalities and underscoring the urgent need for effective healthcare solutions. Responses to climate change appear as organised, systematic and bureaucratic efforts. Nurse educators, pivotal in shaping future nursing professionals through the teaching-learning process, have a significant potential to influence climate change mitigation and adaptation. This article advances the case for individual nurse educator engagement, personal commitment and behaviours in successful climate adaptation and mitigation in nursing education through an argumentative literature review of 11 articles published between 2019 and 2024.
Methods: Argumentative literature review guided by McCullough’s framework.
Results: Nurse educators are influential figures in educational institutions and, through engagement in self-leadership practices, can become agents of change who cultivate environmentally aware students actively engaged in climate change mitigation and adaptation.
Conclusion: Nurse educators’ personal engagement, self-leadership, self-ownership for health, and deep connection to nature are essential for effectively teaching climate adaptation and mitigation in nursing education, influencing environmental sustainability. Support from institutional leaders enhances educators’ ability to foster climate-smart practices
Symmetrical drug-related intertriginous and flexural exanthem with itraconazole: The unusual reaction with a frequently used drug
Authors: Goyal Sheenu , Kumar Sumir , Brar Balvinder , Mehta Arnav
Published: February 2025

Symmetrical drug-related intertriginous and flexural exanthem (SDRIFE) is a rare, benign and self-limiting cutaneous adverse drug reaction. It presents as an erythematous rash distributed symmetrically on the gluteal and intertriginous areas with no systemic affection. SDRIFE is most commonly reported after exposure to antibiotics, particularly those in the penicillin group. Here, we present a case of SDRIFE associated with itraconazole. A 15-year-old boy presented with a dermatophytic infection for which itraconazole was prescribed. After 10 days of drug intake, he presented with diffuse erythema and scaling over the buttocks. The rash continued to progress to other intertriginous areas and was associated with itching and a burning sensation. On examination, an erythematous scaly macular rash symmetrically involving groins, thighs, neck, axilla, flexural aspect of arms, popliteal fossa and upper part of chest was noted. There was complete resolution of the lesions after 2 weeks of stopping itraconazole. The patient was, thus, diagnosed with SDRIFE due to itraconazole, based on the drug history and clinical profile. Although SDRIFE caused by itraconazole is exceedingly rare, increasing awareness among dermatologists can facilitate early identification and prompt discontinuation of the medication.

This study aims to evaluate the effectiveness of excimer laser vision correction in adult patients with partially accommodative strabismus. The study included 24 patients with horizontal strabismus: 14 with fully refractive accommodative esotropia and 10 with partially accommodative esotropia. Preoperative assessments included uncorrected visual acuity, best-corrected visual acuity, manifest and cycloplegic refraction, and the angle of strabismus measured using prism lenses. Patients underwent excimer laser vision correction using LASIK and FEMTO LASIK methods. One year postoperatively, all patients showed significant improvement in uncorrected visual acuity to 0.8–1.2, reduction in refractive anomalies, and a significant decrease in the angle of strabismus. In 75 % of cases, excimer laser correction eliminated the need for further strabismus surgery. Patients reported improved quality of life due to enhanced visual functions and cosmetic appearance. This study confirms the high efficacy of excimer laser correction for treating partially accommodative strabismus in adults. However, further research is needed to fully understand the long-term safety and effectiveness of this method.

Published: February 2025

Material and methods. The study was conducted of various aspects about the using of two FSL systems – LenSx (Alcon) and FEMTO LDV Z8 (Zimmer) in treatment of 100 patients (100 eyes) with immature ARC, including 35 men and 65 women aged from 61 to 76 (on average – 67.7 ± 5.2) years. Eight surgical and five non-surgical criteria of laser operation were studied.

Results. The analysis showed that 4 out of 5 non-surgical criteria and 3 out of 8 surgical criteria indicated a favorable advantage of using FEMTO LDV Z8 in ARC surgery.

Conclusions. 1. With most comparable surgical criteria for using of FSL in ARC surgery, the negative factor in the operation of LenSx is the high frequency of induced miosis. 2. The advantages of FEMTO LDV Z8 include its mobility, interface design features, and optimal patient logistics in the operating room.

Nowadays there is a large number of methods for surgical treatment of pterygium proposed by Russian and foreign authors. However, a high level of pterygium recurrence is observed even with the use of combined treatment methods. Repeatedly recurring pterygium has a more intensive growth and invasion into the corneal stroma, limiting ophthalmic surgeons in the choice of surgical intervention. In this regard, we have proposed a minimally invasive and pathogenetically substantiated method for treating repeatedly recurring pterygium. It consists in transplanting the limbal zone containing a pool of limbal epithelial stem cells (LESC) of the same eye — autolimbal transplantation. The autolimbal transplant is fixed with two-component autofibrin glue, which is widely used in the reconstruction of the ocular surface in the clinic of the V.V. Volkov Department of Ophthalmology. During a comparative analysis of the effectiveness of surgical treatment of repeatedly recurring pterygium using two-component autofibrin glue and sutures for fixation of the autolimbal transplant, we found the advantages of glue fixation. In the main group, the use of the adhesive composition statistically significantly reduces the time of surgical intervention, as well as the rehabilitation period of patients. In addition, in comparison with the suture method, two-component autofibrin glue reduces the risk of intraoperative tissue damage and allows for the formation of a transplant of the required thickness. This gives an opportunity for the active use of two-component autofibrin glue as a method of tissue fixation, including an autolimbal transplant, in the surgical treatment of repeatedly recurring pterygium.

Introduction. The functional results after refractive surgery for astigmatism are influenced by the diameter and localization of the femtoflap, the expansion of the ablation zone, its correct centering, and the good functioning of the tracking system.

Purpose of the study were to modify the course of femtolasic surgery in patients with mixed astigmatism using the FemtoVisum and Microscan Visum.

Material and methods. A total of 32 people (50 eyes) with mixed astigmatism were examined. The average value of the cylindrical component was 3.87 ± 0.25 diopters (range 1.25 to 6.25 diopters). The mean thickness of the cornea in the center was 515 ± 5.12 μm (510 to 530 μm). All patients had a significant shift of the optical axis in relation to the center of the pupil and corneal thickness was lower than average. The first stage in the operation was the fixation of the visual axis and the launch of the tracking system on the MicroScanVizum, which gave a clear understanding in terms of further localization of the flap and ensuring the correct centering of ablation. After that, the stage of femtoflap formation was carried out with its positioning after aplanation on the cornea not in the center of the pupil, but taking into account the angle kappa.

Results and discussion. In 42 % of cases, after femtodissection, the presence of a small accumulation of gas was noted, which did not interfere with ablation and the tracking system worked non-stop. Fixation of the visual axis and initiation of the tracking system to the stage of femtodissection provided more accurate centering of ablation, despite the change in the transparency of the stroma. By 12 months after surgery, the result is stable, repeated operations were not performed due to high visual functions.

Conclusions. The results of mixed astigmatism correction on the Visum platforms according to the proposed algorithm are effective, safe, predictable and stable. The proposed operation option allows to personalize the positioning of the femtoflap and ensure the correct centering of the ablation, which reduces the risk of decentration and increases the functional results of the operation.

Purpose. To evaluate the clinical and functional results of implantation of a monofocal intraocular lens RPR-2 (Reper-NN, Russia) after ultrasound phacoemulsification of uncomplicated cataracts within 1 year after surgery.

Material and methods. 109 patients (134 eyes) with uncomplicated cataracts were included in the study. The average age of the patients was 70 years. Data from one IOLMaster 700 device (Zeiss, Germany), the theoretical online Kane formula and the optical A-constant recommended by the manufacturer (A = 119.1) were used to standardize IOL calculations. The observation period after cataract phacoemulsification with intraocular lens implantation (FEC+IOL) is 1 year.

Results. 1 year after FEC+IOL, uncorrected visual acuity on a decimal scale was 0.67 ± 0.03, best-corrected visual acuity was 0.87 ± 0.02, the average deviation of the spherical equivalent from the target refraction was 0.33 ± 0.09, the average deviation of the spherical equivalent from the planned refraction according to Kane is 0.40 ± 0.08. The predictability of the spherical equivalent of the planned target refraction within ± 0.5 D was 52.6 %, within ± 1.0 D — 32.6 %, more than ± 1.0 D — 14.7 %.

Conclusion. The RPR-2 IOL ensures stable refraction and predictable refractive results. Considering the slight hypermetropic shift due to a change in the effective position of the IOL 1 year after the operation, customization of the A-constant is recommended. Further studies with longer follow-up periods are needed.

SMP Negeri 03 Pontianak's traditional music extracurricular programme has achieved a great deal. The traditional music processed and prepared for the province level competition is performed by a Dayak instrument group. The success of the Festival Lomba Siswa Seni Nasional (FLS2N) number one achievement is inextricably linked to the learning methodologies used by educators. The purpose of this study is to present the learning technique for Dayak traditional music extracurricular activities at SMP Negeri 03 Pontianak. The research technique employed was descriptive, combining a case study and qualitative approach. Data were gathered by observation, in-depth interviews with two experts, and documentation. Data validity was achieved using source triangulation procedures and member checks in the last stage, which involved data analysis via condensation, distribution, verification, and conclusion drafting. The study found that four learning styles are used during the Dayak traditional music instruction process: expository, demonstration, problem-based, and collaborative. Furthermore, the teacher's function as a motivator is to encourage students' success in achieving their goals by providing excitement and arousing students' confidence in their ability to win. The implication of this research is that it can provide additional references for cultural arts teachers to have special strategies in order to obtain the desired goals and achievements.

Despite significant advances in cancer treatment, several challenges persist in optimizing effective cargo delivery, including enhancing bioavailability, improving targeted delivery, and overcoming biological barriers for improved tumor tissue penetration. There is an urgent need for versatile carriers capable of dual or multi-functional targeting within a single system without compromising functionality. Here, we present a microcarrier employing a dual surface modification strategy to enhance therapeutic efficacy through controlled, site-specific drug release. This functionalized microcarrier (potential microrobotic platform) integrates two distinct pH-sensitive polymeric nanoreservoirs with different membrane permeability. One nanoreservoir is engineered to release the antitumor agent curcumin in response to the acidic tumor microenvironment, while the second is designed to degrade the tumor extracellular matrix via enzymatic activity, facilitating deeper penetration of therapeutic agents. This dual surface modification approach represents a significant advancement in the customizable integration of multifunctional nanoreservoirs. By leveraging dual compartmentalization, it prevents deactivation and cross-process interference, enabling precise nanoscale combination therapies for microrobotic cancer treatment. These surface-engineered microrobots hold promise for overcoming physiological barriers, ensuring stable cargo transport, and broadening the applicability of microrobotic platforms across diverse cancer types.

Variations in main and side chain lengths, along with the use of end groups of differing nature, are often identified as key parameters influencing phase transition temperatures (cloud point temperatures) in thermoresponsive polymers. Here, we systematically examine the phase transition behavior of thermoresponsive poly(oligo(ethylene glycol)acrylates) with respect to these three factors. Spin-probing EPR spectroscopy is employed to investigate the impact of these parameters below and at the macroscopically observable thermal transition, as well as to characterize the nanoscale inhomogeneities associated with the transition. Optical transmission measurements are conducted to provide a comprehensive understanding of both, macroscopic and nanoscopic, events. Conducting EPR enables the early detection of the onset of the transition temperature range, well before optical detetction. This combined approach enables us to establish the relative significance of these factors in determining the transition temperatures and the collapse processes. With our approach, we find that the (de)hydration behavior of the polymer chains is mainly determined by the length of ethylene glycol side chains but the individual single polymer end groups also have remarkable influence on the collapse behavior. The main chain length is identified as, relatively viewed, having the smallest effect on the thermal collapse on the molecular level.

To strategically realize the epitaxial growth of heterogeneous catalysts, it is necessary to use highly crystalline ceramic materials, which is a major disadvantage of catalyst materials in terms of surface area. Therefore, it is difficult to intentionally apply epitaxial growth in the design of catalyst materials. Against this background, this study reveals that a distorted PdO is epitaxially bonded to the ab surface of Sr3Ti2O7, which is a ceramic material synthesized by calcination at 1273 K, by loading a very small amount of a Pd species on it. Density functional theory calculations suggest that the charge-transfer from Sr3Ti2O7 to PdO induces an epitaxial junction to produce a structural fluctuation of PdO. Pd/Sr3Ti2O7 catalyst with a unique heterojunction exhibits an excellent catalytic activity for the purification of automotive exhaust gases. In addition, the Pd/Sr3Ti2O7 catalyst is more active than the benchmark Pd/Al2O3 catalyst despite its extremely small surface area. This study demonstrates that ceramic materials can be used as catalyst materials by precisely designing their heterojunctions.

This study demonstrates the successful fabrication of 3D-printed, photoactive reactor components utilizing a TiO2-polypropylene composite filament. The reactor components were employed in the photocatalytic reduction of nitrobenzene and the photocatalyzed synthesis of quinaldine. The reactor inserts were subjected to hydrodynamic and reactive characterization. Furthermore, the viability of employing a solid acid as an alternative to a homogeneous acid catalyst was demonstrated for the photocatalytic synthesis of quinaldine. It was determined that the immobilization of the solid acid not only affects the activity but also the selectivity of the reaction. The immobilization of catalysts obviates the necessity for downstream separation and allows for the modification of reactor designs to achieve optimal reaction performance. The selected rapid prototyping approach facilitated the acceleration of development cycles, and the use of multiple parts comprising different chemically active components enabled the tailoring of (photo)chemical reactors, ultimately paving the way for the development of multi-functional reactors for cascade reactions with high performance and selectivities.
