Effect Of Different Variables On The Formulation Of Sodium Alginate Beads

2024-04-08T06:14:00+00:00

This work examined the possibility of encapsulating prednisolone as drug modelling in Na-alginate polymeric beads. Our beads were formulated by ionotropic gelation method using Na-alginate as an anionic natural polysaccharide polymer and Cacl2 as a positive charge cross-linker. Eleven formulations were successfully created, and different variations were evaluated, including Na-alginate concentration ( 0.5, 2, 3) w/v %, Cacl2 concentration (1, 3, 5) w/v % stirring speed (100, 300, 400) rpm, the addition of tween-80 (0, 2.5, 5) ml, washing beads with alcohol, change curing time. The beads were assayed by bead size, morphology, drug loading, encapsulation efficiency, yield and FTIR. The results showed that the best formula was F2 which can be obtained when using a high concentration of Na-alginate (2 w/v %), Cacl2 (5 w/v %), the addition of tween-80 (5ml) with the lowest stirring speed (100 rpm) without increase curing time or washing with alcohol. Also, the FTIR result revealed a shifting of the carbonyl group and a low intensity of the hydroxyl group in the spectrogram of F2, indicating potential hydrogen bond interactions that might have resulted in the creation of beads.

Evaluation of C-Reactive Protein, Interleukin-6, and Neutrophil-Lymphocyte Ratio as Inflammatory Markers in Patients with Chronic Bronchitis Taking Oral Prednisolone in Maysan City Population

2024-04-08T06:13:52+00:00

Background: Clinically, chronic bronchitis is defined as a persistent cough lasting at least three months over the course of two years in a patient where all other causes have been excluded. It is almost invariably described as a feature of Chronic Obstructive Pulmonary Disease (COPD) secondary to smoking.

Patients and methods: Ninety-five Iraqi patients newly diagnosed with chronic bronchitis were selected to participate in this study. Sixty patients (40 male and 20 female) were enrolled in the current study their ages were ranged from (40-65 years).

The patients were divided into two groups, in the first group (responders’ group) the patients were responded to oral prednisolone therapy, and in the other group the patients were not responded to oral prednisolone therapy (non-responders’ group). The assessment of responsiveness to prednisolone will be according to ATS (American Thoracic Society) which define the responders as those with a response of >12% baseline and >200 ml of FEV1. This study is a prospective observational clinical trial was carried out in thoracic consultant clinic at Al- Sader teaching Hospital in Maysan city from March 2022 until March 2023. The prednisolone tablets given in a dose of 30mg /day for 14 days.

Aim of the study: The current study was aimed to identify the association of the inflammatory markers C-reactive protein, interleukin-6 and neutrophils-lymphocytes ratio with the response of chronic bronchitis patients to oral prednisolone therapy.

Results and Conclusions: CRP, IL-6, and NLR consider as good predictive markers (P value<0.001) to determine the responsivity of patients with chronic bronchitis taking oral prednisolone tablets for 14 days.

Molecular Modeling, Synthesis, and preliminary pharmacological evaluation of New Sulfonamide Derivatives as Selective Carbonic Anhydrase XII and IX inhibitors (Research)

2024-04-08T06:13:49+00:00

New benzene sulfonamide compounds 4–10 was modeled at the molecular level to reveal binding opportunities, bond length, angle, and energy scores in the CA II, CAXII, and CAIX active sites. To test their cytotoxic effect against the AMJ-13 Iraqi breast cancer cell line,

researchers synthesized the promising compounds from 4-(2-mercapto-4-oxoquinazolin-3(4H)-yl) benzene sulfonamide 3. Derivatives 4–10 have IC50 values between 0.10 and 6.47 M, indicating potent action against the AMJ-13 cell line. The most effective of these compounds were numbers 4, 7, and 10. The highest binding scores in the active site of CAXII and CAIX were seen for the most active drugs, which may explain their inhibitory profile.

The incidence of coxiella infection in Iraqi women with early pregnancy loss

2024-04-08T06:13:56+00:00

Query fever is a bacterial disease resulting from Coxiella burnetii (CB) infection in animals. It is well known that small ruminants who get Q fever lose their babies. People think pregnant women may also have lousy gestation results if they get the infection or the infection comes back to life during pregnancy.

This study looks at how serologic results of Q fever and early pregnancy loss (EPL) are linked. In Baghdad, including Madinat Al-Imamain Al-Kadhmain Teaching Hospital and Abu Ghraib Hospital, multicenter case-control research was conducted from September to December 2022. A total of 90 women were enrolled in this investigation. Sixty clinically suffered from early pregnancy loss by having a nonviable intrauterine pregnancy. The other 30 women were subjects of comparable age, the week of pregnancy, and the healthy subjects as controls. Using a commercial enzyme-linked immunosorbent assay (ELISA), serum samples were screened for antibodies against CB. Three (5%) cases tested positive for CB by ELISA. The study reveals no association between adverse gestation outcomes and positive Q fever serology. Age and abortion history were not significantly correlated with C. burnetii seropositivity, according to the findings of CB cases that tested positive results.

The designed structures possessing thiazolidine-4-one heterocyclic moiety were evaluated for their in vitro antibacterial and antifungal activities and were found to exhibit antifungal and antibacterial properties. Molecular docking studies were conducted to examine the potential drug-protein interactions. Molecular characterization by spectral techniques (FT-IR, ¹³C NMR and ¹H NMR) was carried out to confirm the identity of the synthesized compounds.

In Silico Profiling of Histone Deacetylase 8 Inhibitory Activity: A Computational Analysis of Novel Dipeptide-Based Compounds Cross-Linked with Hydroxamic Acid

2024-04-08T06:27:23+00:00

This study involved the development of innovative compounds consisting of dipeptide cross-links combined with hydroxamic acid. Our objective was to assess their binding affinities with histone deacetylase 8 (HDAC8) by conducting a docking study, comparing the results with the reference ligand, suberoylanilide hydroxamic acid (SAHA).

Docking scores were measured in terms of ΔG (Kcal/mol), and the recorded scores for compounds 2A-D were found to be higher than that of SAHA, with values of 87.36, 80.46, 79.42, and 74.14, respectively. Notably, compound 2A, a dipeptide consisting of L-tryptophyl-L-tyrosine linked to a hydroxamic acid moiety, exhibited the highest docking score of 87.36. This finding suggests that compound 2A may possess the most potent HDAC8 inhibitory activity among the other designed compounds. Furthermore, we utilized the SwissADME server to predict the physicochemical properties and additional ADME parameters for the designed compounds. The analysis revealed that all investigated compounds exhibited a high potential for passive oral absorption and demonstrated no penetration into the blood-brain barrier. Compound 2A, 2B, and 2D exhibited one Lipinski's rule violation each, whereas Compound 2C demonstrated no such violations in all parameters. Additionally, compounds 2A and 2C exhibited potential as P-glycoprotein (P-gp) substrates. SAHA did not exhibit inhibition of any of the cytochrome P450 (CYP) enzymes used in this study, whereas compounds 2B, 2C and 2D displayed possible inhibitory activities. These compelling findings provide encouraging prospects for the future synthesis of the designed compounds and warrant further evaluation through in vitro and in vivo biological studies.

the Formulation and Characterization of Curcumin 12-Hydroxystearic Acid in Triacetin Organogel for Topical Administration

2024-04-08T06:28:30+00:00

Background: Curcumin (CUR) and its derivatives have shown a wide variety of biological activities, such as anti-oxidant, anti-inflammatory, anti-tumor, antimicrobial and antiparasitic effects as well as for the treatment of skin diseases. Due to its physico-chemical limitations such as low aqueous solubility and low bioavailability,

we developed curcumin organogel as a topical delivery system to overcome those limitations. The12-hydroxystearic acid (12-HSA) is well known as a low-molecular-weight organogelators (LMOGs) capable of gelling an organic liquid phase. Different concentrations of (12-HSA) in triacetin with 50 mg CUR were gelled and applied for various examinations: tabletop rheology, oil binding capacity, pH measurement, spreadability, in vitro drug release, antibacterial activity and oscillatory rheology studies. The results revealed that the organogels transition temperatures from solid to liquid were greater than the normal body temperature, this helped the organogels keep their shape; they had good spreadability,and the organogels pH levels were within the safe range for the skin . In vitro release data showed that 4% 12HSA+5%CUR +TA (4TA) gave us 100% release after 6 hours. The selected 4TA illustrated good viscoelastic properties in the amplitude sweep test and a frequency-independent as seen in the frequency sweep test. CUR has good antibacterial action against Staphylococcus aureus; Streptococcus pyrogen, Proteus mirabilis, and Escherichia coli, which prevail at the site of wound injury as this pointed out that 4TA organogel can be used for topical wound healing.

Evaluating Serum Calprotectin and Serum Oncostatin M Levels as Diagnostic Markers in Crohn's Disease and Ulcerative Colitis Iraqi Patients. Research

2024-04-08T06:26:13+00:00

Abstract

Introduction: Inflammatory bowel disease (IBD), comprising Crohn's disease (CD) and ulcerative colitis (UC), presents as chronic gastrointestinal inflammation. Timely diagnosis and effective monitoring are crucial for better outcomes. This study aims to explore serum calprotectin and oncostatin M as potential biomarkers for diagnosing and monitoring CD and UC. Calprotectin, released during inflammation, and oncostatin M, an immune-response cytokine, have shown promise, but their precise role in IBD remains unclear.

Methodology: Using a cross-sectional observational design, the study included 93 IBD patients on biological treatment (50 CD, 43 UC) at Baghdad Teaching Hospital. Demographic data and disease characteristics were collected via interviews, and blood samples were analyzed using specific ELISA kits for calprotectin and oncostatin M levels.

Results: The results demonstrated significantly elevated serum levels of both biomarkers in IBD patients, increasing with disease activity. Significant distinctions were observed among different disease statuses in UC and CD patients.

Conclusion: These findings suggest that serum calprotectin and oncostatin M have potential as practical and non-invasive biomarkers for diagnosing and monitoring IBD. However, further research is required to validate their clinical utility and optimize IBD management.
