Research Abstract
Background
Lung cancer (LC) is one of the leading causes of death worldwide. Programmed cell death receptor 1 (PD-1) interacts with its ligand (PDL-1) on T cells inhibiting its functioning which may affect the patient's immunological response.
Aim
Investigate if there is a link between smoking and tissue expression of PDL-1 and vitamin D receptor (VDR) in lung cancer patients. In addition, the relation of vitamin D with smoking and these biochemical markers.
Methods
PDL-1 and VDR expressions were evaluated by real-time PCR in 54 lung cancer biopsy samples and 36 controls to prove this hypothesis. Vitamin D levels in the blood were measured using an ELISA.
Results
Expressions of PDL-1 were significantly upregulated in LC patients than in controls. The highest expression was in stage II and in squamous cell carcinoma followed by small cell carcinoma then adenocarcinoma. However, VDR expressions and …

An updated assessment of the molecular prevalence and risk factors of Babesia infection among crossbred cattle: a diagnostic cross-sectional study

Research Abstract

Abstract
Background Bovine babesiosis is a hemoprotozoal disease that poses a serious danger to cattle productivity in
tropical and subtropical areas. The goal of the current study is to update the data regarding Babesia spp. prevalence.
Assessing the risk variables linked to the illness in crossbred cattle from January to December 2025 in Assiut, Egypt.
Methods A total of 200 blood samples were obtained from crossbred cattle, including 84 apparently healthy and 116
showing clinical signs suggestive of babesiosis. Giemsa-stained blood smears were inspected microscopically, and
molecular analysis that targeted the Babesia 18 S rRNA gene verified the results.
Results The overall prevalence of Babesia spp. infection detected microscopically was 6% (12/200). The percentage
of animals with symptoms was 8.6% higher than in apparently healthy ones. Epidemiological analysis showed higher
infection rates in males (8.33%) compared to females (4.3%), and in cattle younger than one year (8.75%). There was
a discernible seasonal variation in infestation rates, which peaked at 7.7% during the hot season and dropped to
4.2% over the cold season, even though age, sex, and season were not statistically significant (P > 0.05). A significant
association was found between Babesia infection and hard tick infestation (OR = 21.64; 95% CI: 2.35–199.12; P = 0.001)
suggesting that ticks play a critical role in the spread of disease. The presence of B. bovis and B. bigemina in crossbred
cattle in Assiut Province was confirmed by molecular confirmation of a few heavily infected samples using PCR
targeting the Babesia 18 S rRNA gene.
Conclusions For the first time, this work uses combination microscopy and PCR to confirm the existence of two
Babesia species (B. bovis and B. bigemina) in Assiut province, upper Egypt. The data indicate that the parasite is actively
circulating, emphasizing the significance of good tick management and increased diagnostic surveillance in order to
prevent economic losses and maintain animal health.

Camel whey protein coated metal-organic frameworks (CWP/MOF) as a sustainable approach to treat environmental stress-induced liver toxicity by cobalt chloride in rats

Research Abstract
Background and aim
Environmental stressors, such as heavy metal pollution, can have devastating effects on biological organisms, leading to conditions like liver toxicity. This study explored the therapeutic potential of a novel iron-based metal-organic framework (Fe-MOF) in mitigating cobalt chloride-induced liver toxicity in rats.
Methods
Utilizing a solvothermal synthesis method, CWP/MOF was created and characterized using X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy. Adult male rats were divided into four groups, each consisting of six rats. The groups were treated as follows: Group 1 (Control): Received 0.5 ml/day of distilled water only. Group 2 (CoCl₂): Treated with cobalt chloride (100 mg/kg/day) dissolved in distilled water. Group 3 (CoCl₂ + Fe-MOFs): Treated with cobalt chloride (100 mg/kg/day) and Fe-MOFs dissolved in distilled water. Group 4 (CoCl₂ …

Protective effects of whey camel milk proteins conjugate with metal–organic frameworks (MOF) as antimicrobial and against cobalt-induced chloragogen cell toxicity in earthworms

Research Abstract

Camel whey protein (CWP) is rich in potent antioxidant and antimicrobial compounds, while the iron-based metal–organic framework (MOF)-235 offers high biocompatibility for drug delivery. This study synthesised and characterised CWP/MOF-235 nano-conjugates to enhance CWP stability, bioavailability, and therapeutic efficacy. GC–MS analysis confirmed the presence of hepatoprotective and antimicrobial fatty acids in CWP, including oleic acid, palmitic acid methyl ester, and cis-vaccenic acid. Antimicrobial assays revealed that CWP/MOF-235 exhibited greater activity against Candida albicans than CWP or MOF-235, achieving a maximum inhibition zone of 36.3 mm. Using earthworm (Aporrectodea caliginosa), cobalt chloride-induced chloragogen cell toxicity was effectively ameliorated by CWP/MOF-235, restoring normal intestinal histoarchitecture and reducing cellular necrosis as confirmed by light …

APOE‐associated disease risk and sex‐specific effects in Egyptian Alzheimer's disease: an exploratory study

Research Abstract

INTRODUCTION

The apolipoprotein E (APOE) gene is the strongest known genetic risk factor for late-onset Alzheimer's disease (AD), particularly the ε4 allele. Evidence suggests that women carrying at least one APOE ε4 allele have a higher risk of developing AD compared to men. However, data addressing genetic risk and sex-specific effects in Middle Eastern and North African populations remain limited.

METHODS

To address this gap, we evaluated APOE allele frequencies, their association with AD risk, and their contribution to sex-specific variability in a cohort of 63 clinically diagnosed AD patients and 201 cognitively healthy controls recruited across Egypt.

RESULTS

The APOE ε3 allele was the most prevalent in both AD cases (83.3%) and controls (83.6%). The ε4 allele was more frequent among AD patients (12.7%) than controls (8.0%) (adjusted odds ratio [OR] = 1.09, 95% confidence interval [CI]: 0.46 to 2.49, p = 0.85), while the ε2 allele was less frequent in AD patients (4.0%) compared to controls (8.5%) (adjusted OR = 0.82, 95% CI: 0.24 to 2.36, p = 0.73). However, neither association reached statistical significance after Benjamini–Hochberg false discovery rate correction. Sex-stratified analyses revealed no significant sex-specific effects of APOE alleles.

CONCLUSION

This pilot study provides the first characterization of APOE genotype and allele frequencies in Egyptians with clinically confirmed AD. No statistically significant association was observed between APOE status and AD risk in either males or females. Larger, geographically representative studies are needed to further elucidate the role of APOE in AD susceptibility within the Egyptian population and to explore potential alternative genetic or environmental contributors.

Physical disability, cognition, and depression as determinants of quality of life in multiple sclerosis: a cross-sectional study

Research Abstract

Background:

Quality of life (QoL) in multiple sclerosis (MS) is multifactorial, reflecting the combined effects of physical disability, cognitive impairment, and depressive symptoms. While physical disability is a key determinant, the independent contributions of cognition and depression to QoL remain incompletely defined. This study aimed to assess the frequency of cognitive impairment and depressive symptoms in MS and examine their independent impact on QoL beyond physical disability.

 

Methods:

This cross-sectional study included 242 patients with clinically definite MS who were evaluated using standardized clinical and neuropsychological measures. Physical disability was assessed by the Expanded Disability Status Scale (EDSS), motor function by the Nine-Hole Peg Test (9-HPT) and 25-Foot Walk Test (25-FWT), cognition by the Symbol Digit Modalities Test (SDMT), California Verbal Learning Test (CVLT), and Brief Visuospatial Memory Test-Revised (BVMT-R), depression by the Hamilton Depression Rating Scale (HAM-D), and QoL by the MS Impact Scale (MSIS-29). Hierarchical multiple regression was performed to identify independent predictors of total QoL. In this study, cognitive impairment was defined as performance ≥1.5 standard deviations below normative means on at least one cognitive test, and depressive symptoms as HAM-D ≥ 8.

 

Results:

Cognitive impairment was present in 47.9% and depressive symptoms in 61.3% of the cohort. EDSS showed the strongest correlation with MSIS-29 total score (r = 0.698, p < 0.001), followed by HAM-D (r = 0.438, p < 0.001) and BVMT-R (r = −0.340, p < 0.001). In regression analysis, physical disability (β = 0.65, p < 0.001), depression (β = 0.23, p < 0.001), and processing speed (β = −0.12, p = 0.009) were independent predictors of QoL, explaining 64% of its variance.

 

Conclusion:

Although physical disability remains the dominant determinant of QoL in MS, depressive symptoms and cognitive slowing contribute independent and clinically meaningful effects. Routine screening and early intervention for mood and cognitive disturbances are essential to improve overall well-being in patients with MS.
