TREATMENTS FOR ACUTE LYMPHOBLASTIC LEUKEMIA: A COMPARISON BETWEEN TISAGENLECLEUCEL AND CLOFARABINE

Background: Acute lymphoblastic leukemia (ALL) is a heterogeneous hematological malignancy predominantly affecting individuals under 20 years of age. Traditional chemotherapy, such as clofarabine, has shown efficacy; however, novel immunotherapeutic strategies like tisagenlecleucel (Kymriah®) have significantly altered the treatment paradigm. Aim: This study aimed to perform a comparative analysis of tisagenlecleucel, a CAR-T cell therapy, and clofarabine, a second-generation purine nucleoside analog, evaluating their mechanisms of action, therapeutic benefits, limitations, and clinical applicability across diverse patient populations. Methods: A systematic comparative evaluation was conducted, encompassing pharmacological characteristics, mechanisms of action, treatment protocols, efficacy, safety profiles, and clinical indications of both agents. The analysis considered pharmacokinetic and pharmacodynamic data and included patient demographic variables. Results: Tisagenlecleucel demonstrated high efficacy in refractory B-cell ALL, with durable responses and a blood half-life of 128 days, but with notable immune-related adverse effects such as cytokine release syndrome. Clofarabine, effective across a broader patient population, acts via multiple antitumor mechanisms but carries significant toxicity risks, including infection and sepsis. Discussion: The therapies present distinct clinical profiles: tisagenlecleucel offers targeted immunotherapy with high specificity but requires specialized infrastructure and management of immune toxicities. Clofarabine is more widely accessible and applicable, but is associated with conventional chemotherapy-related side effects. Treatment accessibility and cost differ markedly between the two. Conclusions: Therapy selection should be personalized based on patient-specific factors and institutional resources. Tisagenlecleucel is ideal for pediatric and young adult patients with relapsed/refractory B-cell ALL in CAR-T-capable centers, while clofarabine remains a viable option for broader ALL populations, particularly when genetic therapies are not feasible. Further research is needed to optimize therapeutic strategies and improve access to advanced treatments.

RESEARCH LANDSCAPE OF REPURPOSED MEDICATIONS IN CANCER TREATMENT: A MULTI-DATABASE BIBLIOMETRIC ANALYSIS OF ELEVEN OFF-PATENT THERAPEUTICS

Background: Drug repurposing offers potential advantages for cancer therapy development, particularly when utilizing medications with established safety profiles and expired patents. While individual repurposed medications have been investigated for oncological applications, comprehensive comparative analyses of research distribution patterns across multiple therapeutic candidates appear limited in the literature. Understanding these patterns may provide insights into research priorities and potential knowledge gaps. Aim: This exploratory study was designed to quantify and compare the volume of scientific literature examining the anticancer potential of eleven selected off-patent medications across different pharmacological classes. Methods: Bibliometric searches were conducted across five databases (Google Scholar, BVS, PubMed, NIH, and Science.gov) using standardized search terms combining each medication name with "cancer" and "cancer treatment." The selected medications included ivermectin, fenbendazole, mebendazole, albendazole, metformin, propranolol, disulfiram, valproic acid, thalidomide, dexamethasone, and hydroxychloroquine. Basic statistical analyses were performed to examine the distribution patterns and correlations within the database. Results: The search yielded 3,226,066 total publications with considerable variation in distribution patterns. Dexamethasone accounted for the largest proportion (1,538,058 publications, 47.68%), followed by metformin (697,172 publications, 21.61%). Some medications with smaller overall publication volumes demonstrated higher proportions of treatment-specific research, such as fenbendazole (87.82%), disulfiram with copper (86.54%), and hydroxychloroquine with zinc (75.21%). The Herfindahl Index indicated a high concentration of research attention (0.2870). Discussion: The findings suggest substantial variation in research attention across the selected medications. While some medications dominate the literature, others with focused treatment-specific research may warrant further investigation. The inverse relationship observed between total publication volume and treatment specificity suggests that research patterns in this field may be more complex than absolute publication counts indicate. Conclusions: This preliminary bibliometric assessment reveals an uneven distribution of research attention among repurposed medications being investigated for cancer applications. These patterns may inform future research prioritization, though further qualitative analysis would be valuable to assess the clinical significance of these quantitative observations.

A COMPARATIVE STUDY ON THE RESPONSES OF TWO LINES OF SUGAR BEET (Beta vulgaris L) TO SALINITY

Sugar beet is a crop able to resist high levels of soil salinity after emergence and establishment. Considering the significant difference in the effect of nitrogen forms on sugar beet performance under normal conditions, the form of nitrogen may affect the performance of sugar beet plants under abiotic stress, particularly salinity. Additionally, exploring the most appropriate type of nitrogen for sugar beet could mean optimizing sucrose content. Therefore, here using two lines, sugar beet was grown in pots (filled with 4 kg soil), salt-resistance (line 7233- p.29 x Mst), and salt-sensitive (line 3929-21939), the effect of two different forms of nitrate in the form of calcium nitrate (1 g per pot) and ammonium in the form of ammonium sulfate (1 g per pot) under normal and salt stress condition (40 Millimoles per liter sodium chloride) were evaluated. The result revealed the positive influence of nitrate over ammonium by indicating higher dry weight in both sensitive line: 19.2 and 13.6 g, and tolerance line: 20.4 and 13.6 g, respectively alone and in combination with salinity stress. Similarly, root yield levels positively influenced by nitrate treatment either alone or under salinity stress (sensitive line: 194.5 and 243.2 g and tolerance line: 207 and 249.5 g). The outcomes additionally showed the accumulation of proline aerial parts in both lines, and however, the proline accumulation of sensitive line was higher (3.9 mg/g dry weight). Moreover, induction of proline aggregation was considerably higher in nitrate nitrogen-treated sensitive line (9.3 mg/g dry weight). The absence of significant difference was obseved between nitrogen treatments in terms of extractable sucrose and root molasses sugar. Also, the root impurities increased in those treated with nitrate-nitrogen and salinity. It can be concluded that nitrate-nitrogen has improved the performance of both sugar beet lines against salinity stress, and its practical application is adviseable.

NATURAL EXTRACTS AS A PROMISING SOLUTION FOR GRAM-POSITIVE ANTIBIOTIC RESISTANCE: A COMPREHENSIVE REVIEW

Background: Antibiotic resistance is currently one of the biggest problems in public health. Infectious diseases are the second human death cause, and the emergence of antimicrobial-resistant bacteria increases mortality and morbidity rates. There is a growing clinical need for the development of new antibiotics. In this line, WHO issued an alert about 12 bacteria with an urgent need to develop new antibiotics. Aims: This review aims to analyze the current knowledge of their antibacterial activity against the gram-positive pathogens listed by WHO and their extraction techniques. Methods: We systematically reviewed the literature in PubMed, searching publications describing the use of natural extracts as antibiotics over bacteria. The exclusion criteria consisted of limiting papers on natural extracts tested over the bacteria culture related to eleven selected bacteria, according to an alert issued by WHO in 2017, and seven plant extracts. Results: All the gram-positive bacteria present in the WHO alert have been treated, with different degrees of advance, with some of the plant extracts and plant-based compounds reviewed. Currently, they are in the preclinical stage. Edible herbs are more often used, as well as artemisia and wine byproducts. Discussion: Natural products based on plants have shown to be efficient in inhibiting bacterial growth, even in antibiotic-resistant strains. The classical extraction methods are still in use and have been improved with the available technology to improve efficiency and yield. Conclusions: Ongoing evidence shows that plant extracts and plant-based compounds are effective as antibacterial, with minimal effects on the host cell, a promising antibiotic source. Furthermore, they are sustainable, environmentally friendly, and renewable.

MOLECULAR MODELING, REACTIVITY PARAMETERS, AND SPECTROCHEMIC STUDIES OF e-CAPROLACTAM AND o-PHENANTROLINE

Background: Recently, research has been carried out to improve the efficiency of electronic devices in general. With the commercial search for consolidated materials and the growth in demand with monitoring of costs, research has sought to minimize these effects with the replacement or functionalization of other substances, which may be applied at lower costs without compromising operating yields already achieved. Objective: This work aimed to obtain molecular modeling and reactivity parameters of -caprolactam and o-phenanthroline to evaluate the interaction capacity in the formation of molecular systems. Conductance measurements were taken to observe the electrolytic behavior. Infrared and UV-visible spectra were recorded to characterize vibrational transitions and evaluate spectrochemical properties. Methods: The WebLab program was used to obtain structural data and calculate reactivity parameters. Conductance was obtained in QUIMIS Q-405 equipment. IR spectra were recorded on PERKIN ELMER FRONTIER equipment. UV-vis spectra were recorded in a SHIMADZU equipment 200 – 1000 nm range to record the main transitions. Results and Discussions: Electron donor atoms are centered mainly on oxygen and nitrogen, respectively, which are sterically more favorable. The behavior was non-electrolyte. Groups with vibrational transitions sensitive to chemical interactions are comprised of C=N, C-N, and C=O bonds. The  parameter indicates transitions in the 190 – 300 nm region and the near-infrared, and the oscillator strength is typical of molecules used as dyes and sensitizers in optical light-emitting systems or light-to-electricity converters. Conclusions: We observed that these ligands have a donor capacity for the formation of complex systems that meet the need for electron transfer in optical pumping devices for the intensification of transitions or radiation converters, which can also be applied in radiation-to-electricity converter systems.
