There have been several major advances in molecular microbiology in recent years and this review is aimed to describe a few advancements; predominantly focusing on the mitigating the environmental impact, molecular epidemiology of infectious diseases, bioremediation for environmental protection and conservation, pharmaceutical drug development, genome editing and gene therapy, and industrial biotechnology for sustainable food production. Apart from the conventional techniques; modern molecular biotechnology techniques such as transgenic DNA technology are successfully used in crop improvement. Genome editing is a powerful new tool for making precise alterations to the genetic material of an organism which has revolutionized in functional genomics and crop improvement. Molecular epidemiology has grown rapidly in the identification of infectious agents, transmission studies, distribution, responses, population dynamics of the pathogen, and the development of more effective vaccines based on modern advancements. Most of the pathogenic diseases have remained with none of the therapeutic drugs for a cure while the molecular microbiological and recombinant DNA technology approaches are promising methods in discovering new pharmaceutical drugs. Biotechnology has evolved into the best solution for the current food-yield problem; and genetically modified organisms play a key role in the food quality and quantity enhancement processes as a great achievement of biotechnology. Bioremediation is the modern developmental technology that can be applied as a promising approach to cater to the problems arising from polluted surroundings. Advanced molecular microbiological methods should be improvised out of the prevailing methods to get maximum potential despite the limitations.

1.IntroductionThe most common causative agents in CNS infections are bacteria, accounting for 36.70%-63.20% of cases[1], with S.aureus being the most common, and fungal brain abscesses being less common in brain abscesses. Fungal brain abscesses are relatively rare in brain abscesses, accounting for 1.05%-2.38% of cases. Candida is one of the four common fungal genera. Candida is common in Candida albicans, and Candida glabrata (C. glabrata) brain abscesses are very rare[2-3]. Due to its extremely low incidence and lack of specific clinical manifestations and imaging features, the diagnosis of C. glabrata brain abscess is very difficult, and the lack of comprehensive and in-depth clinical and imaging knowledge of it makes it easy to misdiagnose it during diagnosis and treatment as a bacterial brain abscess or other diseases or the failure to choose the appropriate antibiotics in treatment. Based on its cytologic features, it can be diagnosed by cerebrospinal fluid pathogenesis. To the best of our knowledge, few articles have reported diffuse multiple critical C. glabrata brain abscesses. Here, we report a case of multiple C. glabrata brain abscess with typical lesion features of C. glabrata brain abscess on cranial Magnetic Resonance Imaging(MRI) and cranial MR contrast enhancement, which was confirmed by lumbar puncture cerebrospinal fluid pathogenesis.

Rationale: The rapid emergence and structural diversity of new psychoactive substances (NPS) present significant challenges for forensic drug analysis. Existing targeted methods often fall short in accurately identifying novel compounds, increasing the risk of false positives or missed detections. This study aims to address this gap by developing a robust, non-targeted analytical approach capable of confidently screening, identifying, and confirming a broad range of NPS. Method: A method was developed using Ultra-Performance Liquid Chromatography coupled with Quadrupole Time-of-Flight Mass Spectrometry (UPLC-QTOF-MS) to analyze four selected NPS: Mephedrone (4-methylmethcathinone), Ephylone, 2C-B, and Methamphetamine. Analytical parameters such as retention time, mass accuracy (±5 ppm), diagnostic fragments, ion ratios, and isotope patterns were evaluated. The method was validated against critical criteria including precision, stability, and reproducibility. The limit of confirmation (LOC) for each analyte was established, and predictive metabolomics were performed to investigate metabolic transformations. Results: The UPLC-QTOF-MS method demonstrated excellent precision and reproducibility, with consistent retention times and diagnostic fragment ions within acceptable limits. Mass accuracy remained within ±5 ppm, confirming high analytical performance. The established LOC for all analytes was 50 ng/mL. The study also revealed significant metabolic transformations through predictive metabolomics. Compared to conventional tandem MS techniques, QTOF-MS offered enhanced non-targeted screening capabilities and the advantage of retrospective data analysis. Conclusion: The validated UPLC-QTOF-MS method provides a powerful, reliable tool for the rapid detection and confirmation of emerging NPS in forensic samples. Its high mass accuracy, ability to perform non-targeted analysis, and support for retrospective interrogation make it a superior alternative to traditional mass spectrometric methods. This approach enhances forensic laboratories’ ability to keep pace with evolving drug trends and strengthens the integrity of drug-related investigations.

Urban green areas play a crucial role in maintaining biodiversity and providing ecosystem services, but they are impacted by atmospheric pollutants and the deposition of heavy metals. Schinus terebinthifolia Raddi (Anacardiaceae) has been identified as a potential bioindicator, but its physiological and structural responses to pollution require further investigation. This study aimed to assess the ecophysiological and structural responses of S. terebinthifolia to heavy metal contamination in urban areas with different levels of industrial pollution. Leaf chemical composition, as well as morphological, anatomical, and ecophysiological traits, along with soil characteristics, were analyzed in three areas with varying degrees of industrial influence in a medium-sized municipality in southern Brazil. The results showed that plants in more polluted regions exhibited reduced leaf thickness, lower palisade and spongy parenchyma development, decreased stomatal density, and lower chlorophyll levels. Additionally, greater bioaccumulation of zinc and magnesium was detected in leaves from these areas, likely due to the proximity of industries with high emissions. These findings suggest that S. terebinthifolia responds to urban environmental stress by undergoing structural and physiological changes related to air pollution and metal accumulation, thereby reinforcing its potential as a bioindicator.

INTRODUCTIONThe human immunodeficiency virus (HIV) has infected more than 75 million people around the world over the years (Deeks et al. 2015). According to estimates published in 2024 by the World Health Organization (WHO), the total number of people living with HIV corresponds to 39.9 million people, with 38.6 million of those infected being adults and of these, 20.5 million infected people are women, which represents more than 50% of the total infected population. The WHO also describes that the number of people acquiring HIV each year is estimated at 1.3 million people, so it is necessary to establish preventive methods to reduce the acquisition of HIV (WHO, 2024).For the prevention of HIV, an effective mechanism is the pre-exposure prophylaxis (PrEP) in which through a daily dose of the medication called Truvada (tenofovir disoproxil fumarate/emtricitabine), can help to reduce the acquisition of HIV infection, when combined with safe sex practices, the drug was approved in 2012 by the U. S. Food and Drug Administration (FDA). The drug was approved in 2012 by the U.S. Food and Drug Administration (FDA) and is now one of the main tools for preventing HIV infection over the years, being released for use by all subpopulations at risk of infection (Kamitani et al. 2024; FDA, 2012).It is important to emphasize that even though protocols and guidelines have been in place for over 12 years, even with the intense use of oral medication and more recently with the use of injectable PrEP, there is still a lack of inclusion of some subgroups in a more effective way (CDC, 2024). It is currently known that the groups of men who have sex with men (MSM), sex workers and transgender people represent the subpopulations most at risk of HIV infection. However, analyzing the timeline, the data shows that women represent more than half of all those infected over the years and there is also the fact that there is not much research related to cisgender women, the use of PrEP and their adherence to the drug (Nozza et al. 2022).For cisgender women and their subgroups to adhere to PrEP, there are several known barriers and disadvantages, such as society’s stigma towards these women, the lack of effective communication between health professionals and patients, campaigns and advertisements that are not very effective, discrimination, among other problems that prevent women from achieving greater adherence to PrEP and, in turn, more research is required to understand all the factors that are linked to these barriers (Devlin et al. 2023). Given the lack of focus and specificity regarding cisgender women and the fact that adherence to PrEP is not widely known, this scoping review aims to understand PrEP adherence and its effective implementation in high-risk populations, specifically women.

1.     Trophic cascades play a central role in shaping ecosystems, yet how the strength of a trophic cascade responds to warming remains unclear. Because species’ demographics and trophic interaction strengths are temperature sensitive, climate change is expected to alter cascade strengths, with potentially widespread ecological consequences.2.     We experimentally tested how temperature affects trophic cascade strength by manipulating the presence of the predator Hydra oligactis and tracking the abundances of its prey, Ceriodaphnia reticulata, and primary producer, Ankistrodesmus falcatus, across a temperature gradient.3.     To uncover the mechanisms driving these changes, we complemented the experiments with mathematical models fit to the population dynamics, providing novel insight into why trophic cascade strength changes with warming.4.     We predicted that warming would strengthen trophic cascades by increasing direct consumer–resource interaction strengths. Our results supported this prediction, but we also found that higher temperatures amplified population fluctuations, driven by the combined temperature dependence of nearly all the model parameters. 5.     Our findings show that climate warming can strengthen trophic cascades, destabilize population dynamics, and magnify the ecological impacts of predator loss through complex, temperature-dependent changes in species interactions and demographics.

The study by Caglayan et al. offers a significant advancement in our understanding of subclinical cardiac involvement in patients with limb-girdle muscular dystrophy R9 (LGMDR9). Utilizing speckle-tracking echocardiography (STE) and strain-rate imaging, the authors identify regional impairments in myocardial function—particularly in the apical segments—even in patients with preserved left ventricular ejection fraction. These findings underscore the importance of segmental myocardial analysis for early disease detection and risk stratification in neuromuscular cardiomyopathies. In this invited Commentary, we discuss the clinical and research implications of their work, highlight the diagnostic potential of strain-based imaging techniques, and advocate for broader implementation in the longitudinal management of patients with muscular dystrophies. We commend the authors for their methodologically sound approach and for drawing attention to the utility of advanced echocardiographic modalities in rare cardiomyopathies. Their contribution lays the groundwork for future research aimed at refining disease-specific imaging protocols and improving early intervention strategies.

We introduce a coherent theoretical framework that fully explains and links together all physical aspects of the universe making it a suitable candidate for one of the most cherished goals in physics, i.e., 'Theory of Everything'. Working completely within the domain of classical mechanics, we develop this framework by utilizing the tools of Geometric algebra (spacetime algebra). We demonstrate how various theories of quantum mechanics, along with Maxwell's equations, like Dirac equation, Schrödinger's equation, Matrix mechanics, etc., can be derived directly from this framework. We reinterpret special relativity theory and conclude that Galilean invariance is not a limiting case of Lorentz invariance. This framework, endowed with the concept of special theory of relativity, enables us to derive a modified energy-momentum relation, Lorentz force law and a general formula for redshift. We also demonstrate how gauge invariance is just another variation of special theory of relativity. Moreover, we show how gravity can be explained, within this framework, by a modified flat Minkowski metric and without resorting to the curvature of spacetime concept of Einstein. We present how cosmological phenomena like cosmological redshift can be explained by simply using this modified flat Minkowski metric and the general formula of redshift without employing other metrics like the FLRW metric. As a whole, our discussion, ranging from quantum mechanics to cosmology, demonstrates the utility and validity of the presented framework. Additionally, we construct a framework for thermodynamics to explain and provide a foundation to thermodynamic laws. Finally, we derive a modified Navier-Stokes equation with the help of the tools presented in this paper.

Background: Eosinophilic chronic rhinosinusitis (ECRS) is characterized by intense eosinophil infiltration and excessive fibrin formation in the nasal polyps (NPs). The role of the complement system in the pathogenesis of ECRS is not well understood. Objective: This study aimed to evaluate the potential role of complement components in the pathogenesis of NPs. Methods: We measured the levels of thrombin/anti-thrombin complex (TATc), C3a, C5a, galectin-10, and IL-5 proteins in the sinonasal tissue using enzyme-linked immunosorbent assay (ELISA). The effects of the complement components on human eosinophils were evaluated in terms of cell death and regulation of the coagulation system in vitro. Results: TATc, C3a, C5a, galectin-10, and IL-5 levels in NPs were significantly higher in ECRS-NPs than in uncinate process tissue (UT) samples. The levels of C5a, galectin-10, and IL-5 were also significantly higher in ECRS-NPs than in non-ECRS-NPs. A significant correlation was observed between the levels of both C3a and C5a and those of TATc, galectin-10, or IL-5. Eosinophil extracellular trap-forming cell death (EETosis) was spatially co-localized with fibrin deposition in NP tissue. In vitro, co-stimulation with C5a and IL-5 induced EETosis, leading to the exposure of phosphatidylserine due to plasma membrane disruption. C5a and IL-5 also amplified tissue factor gene expression in eosinophils. Conclusions: Elevated levels of complement components in the nasal tissues of patients with ECRS may participate in eosinophil activation, which facilitates fibrin deposition in NPs.

Since the 1970s, the Midwestern USA has experienced an expansion of blacklegged ticks (Ixodes scapularis), the primary vector of Lyme disease caused by Borrelia burgdorferi, leading to increased Lyme disease incidence. Public health surveillance indicates that Northwestern Wisconsin has served as refugia for these ticks, seeding an expansion into neighboring states such as Michigan. However, the process of re-emergence and invasion remains unclear. To improve tick management, we examine whether environmental variables in the Midwestern (eastern North Central) region have constrained tick dispersal and whether connectivity corridors can be identified. By developing fine-scale spatial population genomic data, our analyses reveal genetically diverse populations in Wisconsin, with northern populations contributing to recent expansions within the state. We identify several east-west gene flow corridors facilitating tick dispersal in Wisconsin. An independent dispersal network exists along Wisconsin’s Mississippi River, extending southwards. In contrast, Michigan populations exhibit sharp genetic divergence from Wisconsin and Indiana populations, with low genetic diversity and high in-state gene flow. We also identified high landscape connectivity in the region connecting the Michigan Peninsulas and significant gene flow at the landmass near southern Lake Michigan. Geographical isolation, as well as landscapes with low soil humidity during summer and high human disturbance, were found to limit gene flow across the region, although these effects were minor. Management of blacklegged ticks in the region can be enhanced by recognizing that landscape connectivity has influenced the dispersal of distinct genetic populations, and targeted interventions in seemingly less tick-favorable landscapes may help mitigate the spread.

Visible light communication (VLC) offers a promising alternative to RF in interference-sensitive indoor settings. This study evaluates the luminance distribution performance of VLC systems in office environments, strictly following Malaysian Public Works Department (JKR) standards for 500 lux illumination. Using 120° beam MR16 LEDs, the analysis demonstrated a bit error rates (BER) of 3.43×10⁻⁵ and a data rates up to 1.25 bps at minimal link distances, with consistent performance regardless of room dimensions. The findings demonstrate that a JKR-compliant VLC deployment can simultaneously fulfil lighting requirements and maintain robust communication, paving the way for practical office scale implementations.

Background Cone beam computed tomography (CBCT) and magnetic resonance imaging (MRI) of the equine foot under standing sedation are increasingly available yet there is little published information to guide veterinarians on how both modalities compare to optimise horse management. Objective To describe dual modality CBCT and MRI findings in the equine foot of images acquired in the standing sedated horse on the same day for clinical purposes. Study design Retrospective descriptive study Methods Clinical records, CBCT and MRI DICOM images of patients that underwent advanced imaging with both modalities on the same day (April 2024-April 2025) were reviewed. Key imaging findings were categorised to allow comparison of CBCT and MRI findings. Results Imaging studies of 85 horses met the inclusion criteria resulting in imaging of 120 foot and 38 pastern regions. Twenty-four of 85 horses had a primary soft tissue injury that was detected on MRI but not visible on CBCT. Forty-four horses had increased STIR signal on MRI within the phalanges or navicular bone. CBCT identified small sequestration of the distal phalanx that was identified on MRI retrospectively subsequent to CBCT evaluation. CBCT allowed clearer evaluation of cortical bone specifically at the margins of the flexor cortex of the navicular bone and the articular surfaces of the phalanges. Main limitations Imaging findings were not verified by a gold standard and are subjective and descriptive. Categorical representation of primary diagnosis was difficult for some horses. The horses evaluated are limited to a mixed referral population of horses in Scotland. ConclusionsThe primary diagnosis was provided by MRI in more horses than CBCT due to the ability of MRI to identify soft tissue injury. Combined MRI and CBCT imaging of the foot can provide additional information in horses of solar penetration or where careful evaluation of cortical bone is needed.

Drought is common in the West, and producers need research-based irrigation strategies to stretch limited water supplies. Strategies such as regular maintenance of irrigation components and reducing irrigation rates may be helpful options, but these have not been tested with experimental rigor. This study aimed to identify an inexpensive and straightforward water management strategy to maintain crop yield while reducing water usage. An experiment was conducted at 12 alfalfa (Medicago sativa L.) sites in southcentral Utah in 2019-2020. Alfalfa was cut and harvested two to four times annually at each site. The existing sprinkler equipment (pressure regulators and sprinkler heads/nozzles) on these pivots ranged from 3 to over 20 years old. Three treatments (old equipment, new equipment, and new equipment with a 10% irrigation rate reduction) were applied to one span of the pivot at each site. Results showed that new irrigation equipment did not consistently improve alfalfa yield and quality at any of the sites in either year. In a wet year (2019), many farms were able to reduce irrigation by 10% without sacrificing alfalfa yield and quality. However, some farms experienced significant yield reductions. Over both years, growers could often lower irrigation rates by 10% without adversely impacting alfalfa production. Furthermore, worn sprinkler equipment may not cause as much yield loss as expected.

Plantar warts are a skin problem of great importance due to their prevalence and their negative effects on the patient’s quality of life. Of all the treatments used, the combination cantharidin-podophyllin-salicylic acid (CPS) has shown greater efficacy than the others, although its combination with nitric acid has not been studied. The objective was to analyze the efficacy and safety of the combination of CPS with nitric acid in the first session with respect to the individualized components for the treatment of plantar warts. We analyzed the number of visits and treatment sessions, side effects and evaluated the influence of sex, age range, comparing the combination of SCP and nitric acid in the first session versus the two treatments separately in 196 patients. There were no differences in sex, with a higher incidence in children under 15 years of age. The type of wart was single (86.6%) with a mean size of 6.13 ± 2.91 mm and metatarsal location in 49%. The first visit CPS-nitric acid combination resulted in a mean number of visits of 3.7±2.8, a mean of 2.5±2.9 applications and 45±23 days for lesion resolution, shorter time compared with individualized treatments. A complete resolution was observed in 96.4% of patients treated. The majority side effect was pain (65.5%) with low level on VAS scale (49.7%). In conclusion, the CPS-nitric acid combination was a very high effective treatment for plantar warts with a very fast and high rate for lesions resolution.

Esta pesquisa buscou identificar como a codificação civil contemporânea resguarda elementos presentes na teoria clássica da democracia, reiterando, assim, a concentricidade da teoria democrática ao ordenamento jurídico. A teoria concêntrica da democracia se faz presente desde o o textual constitutivo de uma nação entregando ao ordenamento civil a responsabilidade de continuidade da construção de valores democráticos por legislação complementar, pelo próprio ordenamento base ou súmulas decorrentes de interação civil homem-homem. A pesquisa discorreu-se por aprofundamento bibliográfico tradicional aos temas objeto e por método comparativo de ordenamentos ocidentais e orientais vigentes. Elementos singulares como participação, deliberação e liberdade sempre foram itens indissociáveis à teoria democrática, mas eleitos por vezes como teorias únicas de diversos autores da democracia. Existe uma associação inexorável desses elementos a seus respectivos teóricos e, assim, foi-se delineando a curva de demonstração da ocorrência e existência da democracia. A

Maintaining ecological stability is essential for sustaining ecosystem functions and the benefits they provide to society. Ecological theory predicts that plant diversity either stabilizes or destabilizes local populations, while empirical studies report variable effects. We hypothesize that this discrepancy arises to a meaningful extent from differences in the ecological processes captured by various diversity and stability metrics. Analyzing over 8,000 permanent vegetation plots across biomes on five continents, we found a negative (i.e., destabilizing) diversity–stability relationship when using abundance-weighted rather than unweighted measures of population stability, which are more influenced by dominant species. Similarly, cumulative richness—capturing total species occurrence over time and long-term turnover—reveals a stronger destabilizing effect compared to average annual richness. Our findings reveal that, when specific metrics of diversity and stability are considered, increased interspecific coexistence tends to destabilize populations across natural ecosystems worldwide—particularly those of dominant species.

Low mountain scrub in the Helan Mountains plays an critical role in stabilizing of desert ecosystems in arid and semi-arid region. The interactions and stabilization mechanisms between shrubs and herbs have been one of the core issues in ecological research. Among these interactions, the mycorrhizal network composed of Arbuscular mycorrhizal fungi (AMF) is an important pathway and key factor in nutrient transfer and distribution among plants, influencing the efficient nutrient uptake by aboveground plants. In this study, the dominant scrub community in the low mountainous area of Helan Mountain, the P. mongolica- S. breviflora community, was used as the research object. Two control treatments, sterilized and unsterilized, were established. High-throughput sequencing technology was employed to investigate the mechanism of nutrient partitioning and regulation by AMF on the three vegetation types (shrubs, grasses, and scrub) , and to reveal α-diversity of soil AMF communities and their influencing factors. The results showed that the rhizosphere soil nutrient and plant nutrient contents decreased to different degrees under sterilization compared with the unsterilized treatment. The P. mongolica-S. breviflora community was able to transfer and allocate nutrients by AMF. Nutrient accumulation, rhizosphere soil physicochemical properties, and α-diversity of the AMF community were higher in the P. mongolica-S. breviflora community than in Stipa breviflora and Prunus mongolica single vegetation, which aligns with the ”mutualism” effect of shrubs and grasses. Redundancy analysis (RDA) and structural equation modeling (SEM) showed that the diversity of the AMF community was positively correlated with soil water and nutrient content, which were the main driving factors affecting plant growth and development. High-throughput sequencing revealed that Glomus is the dominant genus in the Prunus mongolica scru b, with an average proportion of 99%. AMF community diversity was significantly correlated with soil organic matter, water content, available nitrogen (AN), total phosphorus (TP), available calcium (AK), and available phosphorus (AP). The structure of the AMF community significantly increased the soil AN, TP, AK, and AP contents. The AMF community structure and α-diversity of rhizosphere soils were also affected by rhizosphere soil nutrients and biological factors, with organic matter and nitrogen being the primary factors, followed by water, phosphorus, and available potassium.This study aims to provide theoretical references for the conservation and stabilization of ecosystem functions and vegetation restoration in the arid and semi-arid areas of the Helan Mountains.

Background: It is imperative to possess a profound comprehension of the physiological and metabolic responses exhibited by equines when subjected to physical exertion. Objectives: To ascertain the correlation between the fatty acid profile and the activity of muscle enzymes in the blood serum of equines and analyse the impact of strenuous physical exertion on these parameters. Study design: Randomised, blinded cross-over in vivo experiments. Methods: The study was conducted on 15 pure-bred Arabian horses divided into groups: -experimental group (GE) (n=7) trained horses, participating in a 40-kilometre sport horse endurance event. -control group (GC) (n=8) neither competing nor trained. Peripheral blood were collected from the GE: three days prior to the commencement of the equestrian event (rest test), one hour and 24 hours after the conclusion of the event; from the GC: was administered rest test. The serum concentrations of CK, AST, LDH were assessed by the Roche Cobas Mira S clinical chemistry analyser. The composition of plasma fatty acids was determined using gas chromatography. Results: Higher AST and CK levels were noted in resting samples from horses undergoing regular training compared to horses that were not trained. Increases in AST and CK levels were also seen immediately after exercise.The demonstrated a positive correlation between regular training of the horses and increased levels of 14;1 and 18;1n-7 fatty acids, while decreased levels were observed for 14;0, 15;0, 16;0, 16;1n-7 and 16;1n-7 fatty acids. Intense exercise influenced the fatty acid profile by raising the proportion of 12;0, 14;0, 15;0, 16;0, 16;1n-7, 17;1, 18;1n-9 and 18;3n-3 fatty acids, and lowering 17;0, 18;2n-6, 18;3n-6 and 22;6n-3 fatty acids. The observed changes were found to be statistically significant or highly significant. Main limitations: Number of animals among groups. Conclusions: Horses used in endurance sports should receive feed supplements rich in omega 6 fatty acids.

Background: Colorectal cancer (CRC) remains a prevalent and lethal malignancy, ranking as the second leading cause of cancer-related deaths globally. Elucidating its molecular mechanisms and identifying diagnostic/prognostic biomarkers are critical for improving survival outcomes. Methods: Survival analysis was employed to unveil the prognostic value of the TIMP1 in CRC patients. Leveraging the TIMER2.0 and TISIDB databases, we systematically analyzed correlations between TIMP1 expression and immune cell infiltration, tumor-infiltrating lymphocytes (TILs), and immune checkpoint gene levels across multiple cancer types. The association between TIMP1 expression and the tumor immune microenvironment in CRC was evaluated using the ESTIMATE algorithm. Differentially expressed genes were identified via the Limma package, followed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses to elucidate TIMP1-mediated oncogenic mechanisms. Protein-protein interactions of TIMP1-binding partners were explored using the STRING database, and Venn diagram analysis combined with Spearman correlation analysis was performed to investigate relationships between TIMP1 expression and co-expressed genes. TIMP1 mRNA levels were validated by Quantitative Real-Time PCR (RT-qPCR). Results: Integrated bioinformatics and experimental data confirmed significantly elevated TIMP1 expression in CRC, which correlated with poor overall survival and disease-specific survival. Notable differences in immune cell infiltration (macrophages, neutrophils, B cells, CD8⁺ T cells, mast cells, monocytes, CD4⁺ T cells, and dendritic cells) were observed between TIMP1-high and TIMP1-low expression groups. TIMP1 expression was significantly associated with TILs, immune checkpoint genes, and immunomodulatory chemokines. Twelve TIMP1-interacting Differentially expressed genes (DEGs) were prioritized: FN1, COL5A1, PRG4, MMP1, MMP2, MMP3, MMP7, MMP8, MMP9, MMP11, MMP13, and MMP14. Conclusion: TIMP1 emerges as a prognostic biomarker and therapeutic target in CRC, with functional implications in modulating the tumor immune microenvironment.

A Markov switching multi-manipulator system composed of heterogeneous nodes with mixed-coupling, driven by a second-order process, and controlled by a multi-weight adaptive controller is proposed. The influence of each parameter on the synchronization properties of the system cluster is analyzed. Through the application of a multi-weight adaptive controller design combined with the Lyapunov method, sufficient conditions are derived to achieve cluster synchronization. Finally, a cylinder production line is given to verify the system.
