Occidentalism: Between Concept and Application
(University of Management and Technology, 2025-04-25) Israa Bassim Mohammed Abbas; Saif Mohammed Sattoori Ibrahim; Sarab Majeed Saleh Abdullah Al-Mohammadi
The current study is concerned with one of the most important matters that the Western world ought to examine scientifically and objectively. It is a counterpart to Orientalism in terms of importance. Its origins go back to the early Islamic eras, represented by the efforts of Muslim travelers and historians. The study adopts a historical, analytical, and descriptive approach which is based on a group of geographical and historical sources and references. It is believed that Occidentalism is an independent science that is concerned with studying the West objectively and is not merely a reaction to Orientalism. The confusion between Occidentalism and Westernization has led to a misunderstanding of this field, which requires correcting the terminology and re-distinguishing between the two concepts. The roots of Occidentalism go back to the early Islamic eras, and its motives are diverse. The study concludes that Occidentalism is a stand-alone science that deserves more careful studies to understand its origins, developments, and goals, away from confusion with Westernization. It also represents an effective means of confronting the Western distortion of Islamic culture and history, by studying it in an objective and precise scientific manner. The study recommends the need to strengthen academic studies on Occidentalism and open new horizons to explore its developments and effects on Islamic and global thought.
A Low-Fouling Electrochemical Immunosensor Based On Metal–Organic Framework and Ternary Metal Oxide Nanomaterials Using Dual Signal Amplification Strategy for Sensitive Detection of Prostate-Specific Antigen (PSA) in Patient Samples

A label-free electrochemical immunosensor based on the zeolitic imidazolate framework-8 (ZIF8)/bismuth ferrite (BFO)
nanocomposite was fabricated for the specific and sensitive quantification of prostate-specific antigen (PSA). The ZIF8-BFO
material not only increases the surface area effectively but also enhances the catalytic capability of the electrode through a dual
amplification strategy, leading to the improved sensitivity of the probe for PSA recognition. A thin layer of l-cysteine was used
for two reasons: providing a scaffold for the next functionalization and reducing the fouling of plasma ingredients on the surface
of the probe. The mechanical and spectroscopic properties of the produced nanomaterials were characterized using different
techniques such as field emission scanning electron microscopy (FESEM), x-ray diffraction (XRD), atomic force microscopy
(AFM), the Fourier transform infrared (FTIR), and dynamic light scattering (DLS)/Zeta analyzer. The electroanalytical properties
of the probe were studied using square-wave voltammetry (SWV) and cyclic voltammetry (CV). The signal of the probe decreased
proportionally with increasing PSA concentration in the 100.0 pg/mL–15.0 ng/mL range, with a limit of detection (LOD) of
85 pg/mL. The proposed platform has been successfully employed to measure PSA levels in human serum samples with acceptable
Histone Deacetylation in Alzheimer’s Diseases (AD); Hope or Hype

Abstract
Histone acetylation is the process by which histone acetyltransferases (HATs) add an acetyl group to the N-terminal lysine
residues of histones, resulting in a more open chromatin structure. Histone acetylation tends to increase gene expression
more than methylation does. In the central nervous system (CNS), histone acetylation is essential for controlling the
expression of genes linked to cognition and learning. Histone deacetylases (HDACs), “writing” enzymes (HATs), and
“reading” enzymes with bromodomains that identify and localize to acetylated lysine residues are responsible for
maintaining histone acetylation. By giving animals HDAC inhibitors (HDACis), it is possible to intentionally control the
ratios of “writer” and “eraser” activity, which will change the acetylation of histones. In addition to making the chromatin
more accessible, these histone acetylation alterations re-allocate the targeting of “readers,” including the transcriptional coactivators, cAMP response element-binding protein (CBP), and bromodomain-containing protein 4 (Brd4) in the CNS.
Conclusive evidence has shown that HDACs slow down the progression of Alzheimer’s disease (AD) by reducing the
amount of histone acetylation, decreasing the activity of genes linked to memory, supporting cognitive decline and Amyloid
beta (Aβ) protein accumulation, influencing aberrant tau phosphorylation, and promoting the emergence of neurofibrillary
tangles (NFTs). In this review, we have covered the therapeutic targets and functions of HDACs that might be useful in
Treating AD.
The Effect of Adding Waste Tire Rubber on Compressive Strength, Impact Resistance, and Damping Ratio of Fiber-Reinforced Foamed Concrete
(Dr D. Pylarinos, 2024-11-09) Oday Asaad Abd; Ameer A. Hilal; Tareq A. Khaleel
Research was conducted to investigate the effects of incorporating optimal proportions of Waste Tire
Rubber (WTR) on the compressive strength, impact resistance, and damping of fiber-reinforced Foamed
Concrete (FC) modified with a Super-Plasticizer (SP). In this study, four FC types with a density of 1100
kg/m3 were produced: conventional FC, modified FC with SP, polypropylene (PP) fiber-reinforced FC, and
fiber-reinforced rubberized FC (containing SP, PP, and WTR). To evaluate the effect of density on the FC
properties, two additional fiber-reinforced rubberized FC mixtures were produced with densities of 800
and 1400 kg/m3. The sand in the FC was partially replaced with WTR at optimum ratios of 50% for coarse
WTR (4.75–10 mm) and 34% for fine WTR (≤ 2.36 mm). Additionally, 53 kg/m3 of cement was substituted
with fly ash. The results indicated that the addition of SP enhanced the properties of the fresh and
hardened FC. For a given density of 1100 kg/m3, adding WTR led to decreased consistency and strength
while increased the impact and damping compared to the reference containing only SP and PP. However,
the fiber-reinforced rubberized FC mix with SP showed improvements of 79.5%, 3700%, and 21.45% in
compressive strength, impact resistance, and damping, respectively compared to conventional FC (without
SP and PP). With the exception of the damping ratio, the compressive strength and impact resistance
increased when the rubberized FC density was elevated.
Prevalence of Dermatophyte Infections in Cats in Ramadi and Fallujah Cities, Iraq
(15/4/2025, 2025-04-15) Khalid Ismael Oleiwi
Background: Dermatophytosis, which is characterized by superficial infection of keratinized 22 tissues, is the most frequent fungal disease in small animal veterinary medicine. Diagnosing 23 dermatophytosis purely according to clinical indications is problematic because dermatological 24 findings vary and various other skin diseases resemble the characteristic fungal lesion. 25
Aim: This study aimed to detect the prevalence of dermatophytes in pet cats with skin lesions who 26 presented to private veterinary clinics in Ramadi and Fallujah cities, Iraq.20
