... Show MoreThe growing emphasis on sustainable construction has prompted interest in repurposing agricultural by-products as alternatives to conventional aggregates in asphalt mixtures. While natural sand is widely available, its use can lead to less stable, more tender mixes, which can limit various specifications. This study explores the potential of palm date seed (PDS) powder as a partial and full replacement for natural sand in asphalt concrete. A series of laboratory tests was conducted to evaluate the effect of PDS incorporation on the mechanical and durability performance of asphalt mixtures, including Marshall properties, resilient modulus, fatigue resistance, moisture susceptibility, and permanent deformation. Additionally, microstructural a
... Show MoreTicagrelor (TCG) is an effective P2Y12 receptor antagonist used to prevent atherothrombotic cardiovascular events; however, its poor solubility and limited permeability (BCS Class IV) restrict its oral bioavailability. Spanlastic Nanovesicles (SNVs), composed of nonionic surfactants and edge activators, offer a promising strategy to enhance drug solubility and permeability. This study aimed to develop and optimize TCG-loaded SNVs using the ethanol injection method, validate a sensitive HPLC method for TCG quantification, and evaluate the pharmacokinetic and antiplatelet performance of the optimized formulation in rats.
A numerical investigation was performed on triangular solar air collectors by integrating unique layouts of triangular and alternating triangular copper metal foams with graded and non-graded pore densities. A three-dimensional CFD model was established to solve the governing equations of coupled systems for porous and non-porous domains. The two-energy-equations model was implemented to simulate heat transfer in porous media. The mathematical model was validated with numerical and experimental tests, with maximum mean absolute percentage error of 5% and 7%, respectively. To compromise heat transfer improvement with pressure losses, a partial metal foam insertion was adopted, covering 10% to 25% of the air duct volume. The findings indicate
... Show MoreDiphenhydramine hydrochloride was determined through a newly developed turbidimetric method on a home-designed continuous-flow injection analysis (CFIA) system. The principle of the method is based on the precipitation-induced signal enhancement, using potassium hexacyanoferrate (III) as a selective precipitating agent. The CFIA manifold uses a flow-through detection cell that consists of 12 white light-emitting diodes and three solar cells placed at 0, 90 and 180 degrees in order to track cumulative light scattering over a range of angles. The systematically optimized chemical and instrumental parameters were the reagent concentration, flow rate and sample volume to attain optimal
Abstract The condition known as gestational diabetes mellitus (GDM) describes as an intolerance to glucoseThat first occur or progresses during pregnancy is the most common metabolic illness, and impacts up to25% of pregnant women. It has been demonstrated that omentin-1, which originates from both human placental and adipose tissue can serve as an insulin resistance mediator. It was initially identified as a secretory factor specific to visceral fat and showed that recombinant omentin-1 administration increased insulin-stimulated glucose transport in vitro which may increase insulin sensitivity, both glucose and insulin can down regulate omentin-1 which reduces levels in overweight women with polycys
... Show MoreStrengthening with carbon fiber-reinforced polymers (CFRP) has become one of the most significant methods of enhancing the flexural strength of reinforced concrete members. Extensive research has shown that externally-bonded CFRP sheets tend to debond from the soffit of the concrete members at much lower strains, compared with CFRP rupture strain. Different types of anchorage system have been developed to prevent or delay the debonding type failure, which leads to a higher utilisation of the CFRP sheets before failure occurs. This paper summarises some of the most efficient types of anchorage systems that have shown significant enhancement in terms of increasing the flexural bending c
Purpose: To evaluate the usefulness of serum cyclin D1, CDK4, and CDK6 as biomarkers of treatment response and progression-free survival (PFS) in metastatic breast cancer (MBC). Methods: In a single-center prospective observational study, 74 women with hormone-receptor-positive (HR+)/ human epidermal growth receptor-2 (HER2)-negative metastatic breast cancer were recruited from the Oncology Hospital, Medical City in Baghdad, Iraq. The patients were treated with oral Palbociclib (125 mg) for 21 days, then continued with Letrozole (2.5 mg) for 7 days, and completed six treatment cycles. The candidates were divided into two groups based on therapeutic response: Group 1 responded to the palbociclib plus letrozole combination therapy, a

Massive efforts have been focused on designing of new anticancer medications. One of these approaches is inhibiting histone deacetylase (HDAC) which have a major role in regulation of cellular epigenetic processes. The non- selectivity of HDAC inhibitors is the major limitation for their use, therefore, recent researches have been oriented toward introducing of selective(HDAC) inhibitors through inhibition of HDAC2 and HDAC6 enzymes. A set of pyrazoline derivatives was designed and virtually studied by means of molecular docking, ADME, and molecular dynamics (MD) simulations. Compound 5 showed promising virtual binding affinity on the HDAC 2 and 6 inhibitors, and exhibited more in silico affinities to (4LXZ)& (5EEI) respectively than SAHA.
