Design and optimization of mRNAs encoding an Anti-TIGIT antibody with therapeutic potential for cancer in TIGIT-humanized BALB/c Mice

Published on: 7th April, 2023

mRNA drugs are synthesized using cell-free systems without complex and stringent manufacturing processes, which makes their preparation simple, efficient, and economical. Over the past few years, mRNAs encoding antibodies have been one of the research frontiers of antibody drug development. In cancer immunotherapy, mRNAs encoding immune checkpoint antibodies may be advantageous regarding antibody persistence and durability of the anti-tumor immune response of patients. In our previous study, a candidate antibody—AET2010—targeting the novel immune checkpoint TIGIT was reported. Its anti-tumor activity was also investigated using adoptive transfer of NK-92MI cells in a xenograft mouse model, but the limitations of the model did not facilitate precise evaluation. In the present study, we further investigated the therapeutic potential of AET2010 for cancer in TIGIT-humanized BALB/c mice. Next, we explored the design, synthesis, and optimization of mRNAs encoding AET2010 and ultimately obtained a candidate mRNA (mRNA-BU) with favorable in vitro and in vivo expression levels of active AET2010. Particularly, lipid-nanoparticle-encapsulated mRNA-BU delivered to mice produced AET2010 with significantly higher peak concentration and expression duration than an equivalent dose of original AET2010. This study provides a sound basis for developing novel drugs targeting TIGIT.

Evaluation of factors affecting the quality of luxury residential buildings using the fuzzy BWM method

Published on: 13th April, 2023

The construction sector consists of a collection of activities related to buildings and engineering constructions of all kinds. It is the close relationship between this sectors with other economic sectors, which distinguishes it. Therefore, it is an important indicator of the movement of the national economy, but this sector faces major risks, especially in the construction of luxury residential buildings, and these risks may affect the implementation of the project and may lead to increase costs, affect the quality and sometimes delay delivery. This study was carried out to evaluate the factors affecting the quality of luxury residential buildings in Iran using the fuzzy best-worst method (fuzzy BWM). The BWM method provides a consistent structural comparison of factors through best and worst criteria. And this method extended using a fuzzy set to address the ambiguity from the decision-maker’s judgment. The evaluation consists of five criteria: Strength and stability, physical comfort and mental peace, visual proportions and beauty, safety, security and environment, and welfare and health. To determine the fuzzy criteria’ weights, the nonlinearly constrained optimization problem was applied. The result indicated that the best and the worst criteria were Visual proportions and beauty and welfare and health.

Cytotoxic Effects of Aminotriles with Bioactive Potential: An Integrative Review

Published on: 9th May, 2023

Aminonitriles are pharmacological-interest bioactive due to their promising antimicrobial and antitumor activity. Since cytotoxicity tests are inherent to the new drug development process, this work aimed to verify reports in the scientific literature on the cytotoxic effects of aminonitriles. The method adopted was an integrative review of works published in the last 10 years in the PubMed, Embase, Web of Science, and Virtual Health Library (VHL) databases. Three articles that matched the selection and eligibility criteria were included in this review. A total of 33 aminonitriles were used in the cytotoxicity experiments, and of the nine molecules based on pyridine, two exerted moderate cytotoxic activity, of the twelve synthesized from benzimidazole, none showed cytotoxic activity, and of the twelve derived from renieramycins, all showed considerable cytotoxic activities. The studies used in this research evaluated the cytotoxic effects of aminonitriles with evident anticancer and antimicrobial activity. The importance of evaluating the cytotoxicity of aminonitriles is emphasized, as well as the need for investigative research that explores other evaluation methods in pre-clinical tests that may corroborate the existing findings, with a view to the development of therapies against emerging health problems.

Perceptions of Adolescent Mothers on Feeding and Nutrition of their Children aged 0-3 Years in Rural Bangladesh

Published on: 16th June, 2023

Proper feeding practices at an early age are the key to improving a child’s overall health and achieving developmental milestones. In Bangladesh, a large portion of rural girls become mothers before the age of 18. Past records show that most interventions are designed to improve infant and young child feeding practices targeting older mothers. That is why, this study has been designed with an aim to explore the perceptions and practices of infant and young children feeding among rural Bangladeshi mothers aged <19 years old. Data was collected through in-depth interviews and group discussions with a total of 40 adolescent mothers who have children aged 0-3 years. Data has revealed that the majority of the mothers hold very limited knowledge of nutrition and child nutrition but those who are educationally a bit ahead hold a little better knowledge. Participants are aware of breastfeeding but they all misinterpret the term ‘exclusive breastfeeding’ with other liquid food. It has also emerged that most of the mothers know the ideal timing of starting complementary feeding but very few of them actually understand what to feed children. In spite of having misconceptions and superstation rural adolescent mothers practice responsive feeding instead of force-feeding. No gender discrimination has been found regarding child feeding. The findings of the study pinpointed that mothers are unable to practice proper infant and child feeding due to a lack of knowledge and limited affordability. Educating girls & young mothers and improving financial security could be an effective way to promote improved infant feeding practices.

Neonatal Mortality Rate among Twin and Singleton Births with the Gestational Age of 34-37 Weeks: A Population-Based Study

Published on: 28th June, 2023

Introduction: Twin pregnancy, compared to a singleton pregnancy, is associated with a higher risk of preterm birth and other neonatal complications. This study aimed to compare neonatal mortality rates and risk factors among births with the gestational age of 34 weeks - 37 weeks in twin and singleton pregnancies.Methods: The study design was cross-sectional and population-based. We extracted the data from the birth information registry in Iran. Mothers' and neonates' information was removed from the registry systems between 2018 and 2020. We used Statistical R software to compare neonatal mortality rate, demographic variables, and risk factors between two groups of twin and singleton neonates.Results: Out of 579,873 live births with a gestational age of 34 weeks - 37 weeks, 729 (1.4/1000) singleton and 54(0.77/1000) twins (one out of two) neonates died in the delivery room in the first hour of life. Of the neonates who left the delivery room alive, 3129 (4.9 per 1000) neonates had died (5.7/1000 singleton and 3.04/1000 twin). The neonatal mortality rate in hospitalized singleton neonates (1.85%) was higher than twin group (1.06%). After adjustment of other variables, the mortality rate in twin pregnancy was significantly lower than in singletons (p value < 1/1000), with an odds ratio of 0.47 (CI: 0.39 - 0.55). Antenatal corticosteroid treatment in the twin group was significantly higher than in singletons.Conclusion: Twin neonatal mortality rate was lower than singletons in the neonates with gestational age 34 weeks - 37 weeks. Clinicians could consider these results for delivery timing in uncomplicated twin pregnancies. Antenatal corticosteroid therapy can be considered to reduce the mortality rate of late preterm neonates in resource-limited countries.

Extracorporeal Membrane Oxygenation in Acute Aluminum Phosphide (AlP) Poisoning

Published on: 28th July, 2023

Introduction: Aluminum Phosphide (AlP) poisoning is a life-threatening condition that commonly occurs in developing countries, often resulting in cardiac, respiratory, and metabolic complications, leading to multi-organ failure and mortality. Extracorporeal Membrane Oxygenation (ECMO) has been proposed as a potential therapy for severe AlP poisoning cases refractory to conventional management, though its use remains controversial. Methodology: for this literature review, we conducted a comprehensive analysis of existing literature concerning the utilization of ECMO in patients with severe AlP poisoning. We meticulously examined available publications to explore the relationship between ECMO initiation and patient outcomes. Discussion: The review reveals that early ECMO initiation within 6 hours of presentation is associated with better outcomes and higher survival rates in severe AlP poisoning cases. However, uncertainties persist regarding the optimal timing and duration of ECMO support, and potential complications, including bleeding, acute renal injury, and ventilator-associated pneumonia, need careful consideration. Conclusion: Despite promising results in certain cases, the risks and benefits of ECMO in AlP poisoning require meticulous evaluation. Ethical considerations, encompassing resource allocation and implications for other patients, necessitate appropriate patient selection criteria.

Prospective Coronavirus Liver Effects: Available Knowledge

Published on: 18th August, 2023

The global pandemic COVID-19, caused by SARS-CoV-2, affected millions of people. COVID-19 is known for its respiratory symptoms, but new research reveals it may also affect other organ systems, including the liver. This abstract reviews COVID-19 and liver function. The virus enters host cells through liver-expressed angiotensin-converting enzyme 2 (ACE2) receptors. Thus, viral infection and replication may target the liver. Virus-induced inflammation and cytokine production may also harm the liver. ALT and AST elevations are the most prevalent liver abnormalities in COVID-19 patients. Liver function test abnormalities frequently indicate serious illness and poor clinical outcomes. COVID-19 may worsen pre-existing liver diseases such as NAFLD and chronic viral hepatitis. Drug-induced liver damage (DILI) from COVID-19 therapies including antivirals and corticosteroids complicates liver complications care. Recent investigations have also shown that COVID-19 may cause long-term liver damage. In conclusion, COVID-19 infection, immune-mediated damage, and treatment problems may severely compromise liver function. Optimizing patient treatment and discovering targeted medicines requires understanding COVID-19's liver role. To reduce the effects of COVID-19 on liver function, further study is required to understand the mechanisms and long-term effects.

Potential Use of Essential Oils and Their Individual Components in Cosmeceuticals: A Review

Published on: 7th September, 2023

The cosmetic industry is searching for new active ingredients from renewable natural sources to make more environmentally friendly and safe products. Botanical extract is a nearly limitless source of these new actives due to the current consumer demands as well as international regulations. Due to both their fragrant nature for the creation of fragrances and perfumes and the numerous advantageous properties of their individual components (EOCs), such as anti-inflammatory, antimicrobial, and antioxidant properties, essential oils (EOs) emerge as a very common natural ingredient in cosmetics and toiletries. Additionally, nowadays, the cosmetic industry includes EOs or different mixtures of their individual components (EOCs), either as active ingredients or as preservatives, in various product ranges (e.g., moisturizers, lotions, and cleansers in skin care cosmetics; conditioners, masks or anti-dandruff products in hair care products; lipsticks, or fragrances in perfumery). However, because each essential oil’s distinct chemical profile is linked to a different set of advantages, it is challenging to generalize about how they might be used in cosmetics and toiletries. Formulators frequently spend time looking for appropriate combinations of EOs or EOCs to achieve particular advantages in the finished products. The literature on the most recent developments in the use of EOs and EOCs in the production of cosmetic products is updated in this work’s review of the literature. Additionally, certain particular issues pertaining to the security of EOs and EOCs in cosmetics will be covered. It is expected that the information contained in this comprehensive review can be exploited by formulators in the design and optimization of cosmetic formulations containing EOs.

Hydrogel-Based Formulations for Drug Delivery to the Posterior Segment of the Eye

Published on: 12th September, 2023

Hydrogel-based formulations hold significant promise for treating ocular diseases that impact the posterior segment of the eye. These formulations exhibit the ability to surmount ocular barriers and offer sustained drug release, rendering them efficacious drug delivery systems. This article addresses the challenges linked to treating disorders affecting the posterior eye segment and underscores the imperative for less invasive drug delivery methodologies. We further delve into diverse contemporary ocular dosage forms, encompassing gels, nanostructures, and implants, with a specific emphasis on hydrogels. Hydrogels offer several merits, including precise targeting, sustained release, enhanced bioavailability, and non-invasiveness. Moreover, they curtail the risk of adverse effects and foster patient adherence. An enthralling advancement is the amalgamation of hybrid drug delivery systems, integrating nanoparticles, liposomes, dendrimers, and stimuli-activated nano-systems, with hydrogels for posterior eye ailment treatment. These hybrid nano-systems exhibit promise in enhancing drug stability, prolonging drug release, and pinpointing specific tissues within the posterior segment. We also provide an overview of ongoing clinical trials and approved hydrogel-based drug delivery systems, like Retisert and Ozurdex. These systems have demonstrated efficacy in managing chronic non-infectious uveitis, Age-related Macular Degeneration (AMD), and diabetic macular edema. Nevertheless, challenges persist, including optimizing bioavailability, maintaining drug stability, and implementing personalized treatment approaches. The incessant evolution of gel-based drug delivery systems stands to substantially enhance patients’ quality of life and establish new benchmarks in treating posterior eye diseases. The future of ophthalmology brims with excitement, as gel-based drug delivery systems hold the potential to revolutionize ocular therapies, providing effective remedies for an array of vision-related afflictions.

Qualitative Identification of Secondary Metabolites and Determination of the Toxicity of Extracts Obtained from the Flower of Kalanchoe Pinnata

Published on: 17th October, 2023

Kalanchoe pinnata, also known as air leaf or life leaf, is a plant used in traditional medicine in different world regions. In Mexico, it is included in the Atlas de la Medicina Tradicional Mexicana with a wide variety of applications, such as antimicrobial, anti-inflammatory, anticancer, and antihistamine, among others. However, neither a secondary metabolite profile of the flower has been reported nor information on its possible toxicity. The latter is the purpose of this work. A phytochemical profile of extracts with solvents of different polarity (aqueous, methanol, ethanol, and ether) was carried out. In this profile, the structural compounds could be qualitatively determined by chemical reactions, and some changes in coloring or precipitation were observed. The acute toxicity test of the extracts was performed with an aquatic organism, Artemia sp, and a terrestrial organism Eisenia foetida, as well as the evaluation of the antioxidant capacity of the extracts in the organism of Eisenia foetida. The ABTS radical method and TROLOX were applied as synthetic antioxidants for the evaluation of the inhibition percentage. Most important secondary metabolites were qualitatively identified in the extracts of K. pinnata flowers. Mainly in the alcoholic extracts (methanol and ethanol) tannins, alkaloids, and flavonols were found. As mentioned above, they are reported to have toxicological effects. The toxicity and antioxidant activity tests confirm the preliminary results obtained in the identification of secondary metabolites. It is therefore concluded that the flower of Kalanchoe pinnata contains secondary metabolites that may be of great therapeutic interest.

Mechanism of Action and Validation of the Traditional Medicinal use of Grewia Tenax Fruits in Sudan to Encounter Iron Deficiency Anemia

Published on: 27th December, 2023

Introduction: In Sudan, Grewia tenax fruits, are known commonly as Goddaim. The fruit’s pericarp is used traditionally for a long time as a juice or a porridge to treat iron deficiency anemia (IDA). Traditional Goddaim users have a very strong belief in its effectiveness. However, the pattern of hemoglobin improvement follows an initial fast increase followed by a decline upon continuing its use. Some previous studies have attributed its effect to high iron content, while the iron quantity was too small. This work attempts to find an explanation for its mechanism of action by screening the fruit extract and its respective fractions for secondary metabolites, minerals, vitamins, and fibre. Methods: Entailed three methodologies: Chemical analysis to identify quantified minerals, ascorbic acid and non-digestible fibers, Phytochemical Analysis to separate and identify secondary metabolites using high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS-MS technique), and estimation of radical scavenging activities of crude fruit extract and its respective chloroform and ethyl acetate fractions by inhibition of the 2,2-diphenylpicrylhydrazyl (DPPH).Results: Ascorbic acid and indigestible fibres were revealed in the aqueous extract. Secondary metabolites were flavonoids (e.g., quercetin, kaempferol), organic acids (e.g., ferulic acid, chlorogenic acid), β-carboline alkaloids (e.g., 3-hydroxy-tetrahydroharman) identified in the chloroform, and ethyl acetate fractions. The in vitro antioxidant activity of G. tenax fruit extract was confirmed spectrophotometrically. Conclusion: It can be concluded that the initial enhancement of iron absorption through ascorbic acid and fibres, followed by iron uptake inhibition, could be explained by iron chelation by the chelators in the fruits. This paradoxical effect may qualify G. tenax fruits as a safety gauge for improving haemoglobin levels without compromising iron excess once iron stores are filled by keeping the oxidative stress in check. This may present G. tenax fruits as a good and safe remedy that optimizes the treatment of IDA.

Tracheotomy in Severe Head Trauma: Early vs. Late

Published on: 19th January, 2024

Introduction: The evolution of a patient with severe traumatic brain injury may require the use of a tracheostomy as part of respiratory weaning. The central question revolves around the optimal timing to replace intubation with tracheostomy. The aim of this study is to evaluate the hypothesis that early tracheostomy reduces the incidence of ventilator-associated pneumonia (VAP), the duration of mechanical ventilation (MV), and the length of stay in the intensive care unit (ICU).Materials and methods: This was a retrospective study including all patients admitted to the department over a period of 08 months. Various historical, demographic, clinical, biological, and progression-related covariates were collected upon admission.Results: Among the 69 patients included in the study who underwent surgical tracheostomy, two groups were formed: those who underwent early tracheostomy (within the first 8 days of mechanical ventilation) and those with late tracheostomy (after 8 days). The early group showed a significant reduction in the duration of mechanical ventilation (16 ± 3 days) and length of stay in the intensive care unit (17 ± 3 days) compared to the late group (23 ± 6 days and 30 ± 11 days, respectively). No significant differences were observed regarding the incidence of ventilator-associated pneumonia (VAP) and mortality between the two groups.Conclusion: This study strengthens the existing literature by demonstrating that early tracheostomy is associated with a reduction in the duration of MV and length of stay in the ICU.

Isolation and Influence of Carbon Source on the Production of Extracellular Polymeric Substance by Bacteria for the Bioremediation of Heavy Metals in Santo Amaro City

Published on: 9th February, 2024

The city of Santo Amaro (Bahia, Brazil) gained visibility among the scientific community due to the contamination of the Subaé River by lead and cadmium from the PLUMBUM Mineração e Metalurgia Ltda industry, on the banks of the river in 1956, which produced lead ingots The present work aimed to investigate the adsorption capacity of heavy metals (Pb and Cd) of EPS produced by bacterial species from the Subaé River, for possible future application of these biopolymers in bioremediation processes in areas impacted by the aforementioned heavy metals. Subaé river water was collected for physical-chemical analysis and bacterial isolation. It was verified that all isolated bacteria produced an expressive amount of Exopolysaccharide (EPS). Thus, the optimization of this production in different sugars (sucrose, glucose, and mannitol) and in three different pHs: 5.5; 6.5, and 7.5. All bacteria produced EPS in large quantities and the best sugar was sucrose at pH 7.5. In order to use the EPS for the bioremediation area, the adsorption test of lead and cadmium was carried out by the isolated EPS. 0.5 g of the EPS was dissolved in 50 ml of deionized water, then the solutions of metals, lead acetate, and cadmium sulfate (procedure performed separately) were incubated at 28 °C for 16 h after that period, and were centrifuged. Samples were filtered to separate the insoluble EPS and the filtrates obtained were used in the quantification of the metals by atomic absorption (FAAS- Flame Atomic Absorption Spectrometry). Bacillus spp., Bacillus cereus, Staphylococcus spp., and Serratiamarcescens, all showed tolerance to the tested metals, due to the efficiency in the adsorption capacity of the EPS, and it was possible to distinguish seven genera, Klebsiella pneumonia, Pseudomonas aeruginosa, Lysinibacillus spp. to be used in the bioremediation of environments contaminated with heavy metals.

Correlation of Inappropriate use of Ceftriaxone and Bacterial Resistance in the Hospital Environment: Integrative Review

Published on: 29th March, 2024

Introduction: Bacterial resistance is a threat to public health, as it is estimated that 37,000 people die due to hospital infections, most of them due to multidrug-resistant bacteria. In part, this resistance is due to the inappropriate use of antibiotics, with ceftriaxone being one of the most used. Therefore, this article aims to analyze the consequences of using ceftriaxone in the hospital environment. Methodology: This is an integrative qualitative review, following the PICO strategy, using the Embase, BVS, and Pubmed databases, with the guiding question being: “In patients admitted to a hospital environment (P), is ceftriaxone used appropriately (I) for the treatment of infections (CO)?” and the time frame from 2013 to 2023. Results: 272 articles were found in total, 46 obtained from the VHL, 62 from PubMed, and 164 from Embase. Of these, 66 were duplicates, leaving 206 works for title and summary reading. After reading, 79 were selected for full reading, with 7 articles ultimately being selected for the study. An average of 62.3% of inappropriate use was found, with the minimum value found being 19% and the maximum being 87.9%. The main reasons for this use were: indication, dose, frequency, and duration. Conclusion: From reading the articles, it is concluded that the inappropriate use of ceftriaxone is mainly due to: indication, dose, frequency, and duration of treatment. These elements must be monitored, as their inappropriate use increases the length of hospital stay and may be associated with the emergence of bacterial resistance.

Antibacterial Screening of Lippia origanoides Essential Oil on Gram-negative Bacteria

Published on: 8th April, 2024

Essential oils (EO) are extracted from different plant species and can be present in different plant organs. Rosemary-pepper EO is composed of around 50% to 70% thymol, a phenolic compound proven to be active against fungi and bacteria. The active components present in these compounds can affect the vital functionality of bacterial cells, leading to protein denaturation and cell lysis. Therefore, the present study aims to evaluate in vitro the antibacterial potential of Lippia origanoides EO against gram-negative bacteria. This is an exploratory study, with a technical-experimental procedure, with a quantitative approach, carried out at the Federal University of Campina Grande. The strains used were Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 25933, and Escherichia coli ATCC 25922, using concentrations of 1024, 512, 256, and 128 μg/ml using the disc diffusion method in triplicate. After the incubation period, the formation of halos of bacterial growth inhibition was not observed. There are possible causes for the lack of antibacterial activity of the EO concerning the strains of gram-negative bacteria used in the study, including the possibility of not containing components with antibacterial properties in concentrations sufficient for the expected activity at the concentrations tested. Based on the results obtained, the Rosemary-Pepper EO (Lippia organoids) did not demonstrate antimicrobial activity against the gram-negative bacteria used in the study. Therefore, the development of new research with Lippia origanoides essential oil with gram-positive bacteria is suggested.

Published on: 2nd April, 2024

Background: Cancer treatment frequently depends on the intricate and potent effects that are acknowledged for their potential to save lives. Chemotherapy can have adverse effects on both the central and peripheral nervous systems, posing significant challenges.Objective: •    To assess the causative agent, development, and timing of occurrence.•    To improve management of neurological complications.•    To discriminate the iatrogenic effects of cancer therapy and neurological progression.Method: A prospective observational study was conducted in a hospital setting, focusing on the neurotoxic effects of chemotherapy in cancer patients over a span of six months. The research involved participants from both the oncology in-patient and daycare departments. After obtaining informed consent, individuals in the study population were interviewed to gather information about any neurological symptoms they encountered following their chemotherapy sessions.Results and discussion: Within our study population, a predominant 67% comprised female patients, while male patients constituted 33%. Of the total participants, 66% reported experiencing neurological symptoms. Among these symptoms, the majority of patients encountered sensations such as tingling, numbness, and a burning sensation. Other reported symptoms included headaches, distal weakness, myalgia, seizures, and ataxia.Conclusion: In this current study, 66% of the study population encountered neurological side effects. Generally, the presence of comorbidities, vitamin deficiencies, and advanced age can significantly contribute to the development of peripheral neuropathy. Depending on the severity of neuropathy, recommendations for interventions include the prescription of vitamin supplements, calcium supplements, duloxetine, and pregabalin.
