    Abstract Allolobophora calignosa (Ac) is a folk medicine for millennia, as it possesses many biological activities. This study aimed to investigate the chemo-preventive activity of A.calignosa coelomic fluid (AcCF) and A.calignosa extract (AcE) on glucocorticoid-induced osteoporosis (GIOP) in mice. Characterization and in vitro biological activity of AcE and AcCF has been assessed. Male CD-1 mice were subcutaneously received dexamethasone (DEX) (1 mg/kg, 5 times/week) and concurrently intraperitoneally treated with either AcCF (20 mg/kg) or AcE (45 mg/kg) every other day for 28 days. Serum and bone homogenates were subjected for qPCR and biochemical analysis. AcE and AcCF treatment significantly increased bone mineral density (BMD), bone mineral content (BMC), calcium (Ca), phosphorus (P), and calcitonin levels, whereas activity of serum alkaline phosphatase (ALP), bone alkaline phosphatase (BALP), serum acidic phosphatase (ACP), bone acidic phosphatase (BACP) and parathyroid hormone (PTH) levels were significantly reduced compare with untreated GIOP mice. Treatment with AcE and AcCF modulates oxidative stress and downregulated Rank and Mmp9 expression, as well as increased glycosaminoglycan content in the organic bone matrix, resulting in osteoclastogenesis inhibition. Overall, AcCF and AcE show a chemo-preventive activity against GIOP by inhibiting oxidative stress and regulating expression and/or activity of osteoblast/osteoclast-related markers.

    Abstract Background: Colorectal cancer is one of the most serious gastrointestinal cancers in Africa and its prevention is a pronounced challenge in contemporary medicine worldwide.
    Objective: The present study aimed to develop nanoemulsion drug delivery system using pomegranate polysaccharides (PGPs) as an alternative cancer remedy, and then the evaluated its biological activities.
    Methods: The PGPs yield and chemical composition were evaluated, and then a PGPs nanoemulsion (PGPs-NE) was prepared using the self-emulsification technique with an oil phase. The physicochemical characterization of PGPs-NE was then analyzed. The in vitro antioxidant, anti-inflammatory activities, and antitumor potency of PGPs and PGPs-NE were also evaluated.
    Results: The PGPs yield was 10%. The total sugar and protein content of PGPs was 44.66 mg/dl and 19.83μg/ml, respectively. PGPs were mainly composed of five monosaccharides including fructose, glucose, galactose, rhamnose, and arabinose. Concerning physiochemical characterization, the formulated PGPs-NE had three optical absorption bands at 202, 204, and 207nm and a transmittance of 80%. Its average hydrodynamic particle size was 9.5nm, with a PDI of less than 0.2 and a negative zeta potential (-30.6 mV). The spherical shape of PGPs-NE was confirmed by a transmission electron microscope study, with an average size of less than 50 nm. Additionally, the method used to prepare the PGPs-NE formulation provided high entrapment efficiency (92.82%). The current study disclosed that PGPs-NE exhibited strong antioxidant, anti-inflammatory, and antitumor agent potency compared to that of free PGPs.
    Conclusion: These promising current findings provide evidence for the possible efficacy of novel PGPs-NE as an alternative treatment for CRC.

    Abstract Background: Coelomic fluid, a pharmacologically active compound in earthworms, exhibits a range of biological activities, including antioxidant, anti-inflammatory, and anticancer. However, the biological activities exerted by the coelomic fluid can be restrained by its low bioavailability and stability. Liposomes are progressively utilized as an entrapment system for natural bioactive compounds with poor bioavailability and stability, which could be appropriate for coelomic fluid. Thus, the present study was designed to fabricate, characterize, and evaluate the stability of liposomal formulation for Allolobophora caliginosa coelomic fluid (ACCF) as a natural antioxidant compound.
    Methods: The ACCF-liposomes were developed with a subsequent characterization of their physicochemical attributes. The physical stability, ACCF release behavior, and gastrointestinal stability were evaluated in vitro. The biological activities of ACCF and its liposomal formulation were also determined.
    Results: The liposomal formulation of ACCF had a steady characteristic absorption band at 201 nm and a transmittance of 99.20 ± 0.10%. Its average hydrodynamic particle size was 98 nm, with a PDI of 0.29 ± 0.04 and a negative zeta potential (-38.66 ± 0.33mV). TEM further confirmed the formation of vesicular, spherical nano-liposomes with unilamellar configuration. Additionally, a remarkable entrapment efficiency percent (77.58 ± 0.82%) with a permeability rate equal to 3.20 ± 0.31% and a high retention rate (54.16 ± 2.20%) for ACCF-liposomes were observed. The Fourier transform infrared spectroscopy (FTIR) result demonstrated that ACCF successfully entrapped inside liposomes. The ACCF-liposomes exhibited a slow and controlled ACCF release in vitro. Regarding stability studies, the liposomal formulation enhanced the stability of ACCF during storage and at different pH. Furthermore, ACCF-liposomes are highly stable in intestinal digestion conditions comparable to gastric digestion. The current study disclosed that liposomal formulation potentiates the biological activities of ACCF, especially antioxidant, anti-inflammatory, and thrombolytic activities.
    Conclusion: These promising results offer a novel approach to increasing the bioaccessibility of ACCF, which may be crucial for the development of pharmaceuticals and nutraceutical-enriched functional foods.

    Abstract Background: Holothuria arenicola is the most important and abundant sea cucumber species in the Mediterranean Sea on the Egyptian coast. The present study aims to assess the anti-oxidative and anticholestatic effects of the sea cucumber Holothuria arenicola extract (HaE) in a model of bile duct ligation in male albino rats.
    Methods: Fifty four male Wistar albino rats were assigned into two main groups, the Sham-operated control and bile duct ligated (BDL) group. After 14 days of surgery, the animals of the group I (Sham control) received distilled water only for 7, 14 and 28 days. Second group (BDL group) was divided into 2 subgroups, animals of these subgroups treated for 7, 14 and 28 consecutive days as follow: subgroup I (BDL), rats of this subgroup administered distilled water orally. Subgroup II (HaE), animals of this subgroup treated orally with HaE (200 mg/kg body weight).
    Results: The HaE revealed significant antifibrotic effect as evident by decreasing the levels of total conjugated and unconjugated bilirubin and the activities of serum aminotransferases (ASAT and ALAT) and alkaline phosphatase (ALP) as well as malondialdehyde (MDA) level, and increasing the serum albumin, glutathione reduced (GSH) levels. Treatment with HaE normalized the antioxidant enzyme, glutathione-S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) activities activities.
    Conclusion: The present prospective study correlated the antifibrotic effect of HaE to its direct antioxidant effect that can be related to its contents of phenolic compounds specially chlorogenic acid, pyrogallol, rutin and coumaric acid.

    Abstract Toxocara vitulorum is a common gastrointestinal nematode of buffaloes and cattle, primarily young calves. This parasitic infection is distributed worldwide, causing a huge economic loss due to reduced meat and milk production and animal mortality. Several studies have indicated that silver nanoparticles have an effective anthelmintic activity. Thus, this study aimed to evaluate the anthelmintic effects of different concentrations of silver nanoparticles on adult Toxocara vitulorum in vitro. Male and female adult worms were incubated for 48 h in 50, 100, and 200 mg/L silver nanoparticles synthesized using lemon juice. Oxidative stress markers, in addition to light and scanning electron microscopic studies of treated worms, were assessed following 48 h incubation in 200 mg/L silver nanoparticles. Light and scanning electron micrographs of treated worms revealed damage in the muscular layer, destruction of the cuticle, distortion in lips structure, and deformed excretory pore and sensory papillae. Also, oxidative stress markers recorded an increase in malondialdehyde and nitric oxide and decreased levels of glutathione reduced, glutathione S-transferase, and catalase after exposure to silver nanoparticles. In Conclusion, the current study demonstrated a substantial destructive effect of silver nanoparticles on adult Toxocara vitulorum, indicating its potential as an anthelmintic alternative to the more expensive drugs.

    Abstract The implementation of principles and guidelines that govern the various areas of research in an educational institution isone of the key factors in international recognition of its research integrity and value. The privilege of conducting research using animal subjects requires adherence to international regulations and standards governing the humane care and use of laboratory animals. The IACUC at our university deemed it critical to have an animal care and use training program to raise researchers' understanding and knowledge. Our IACUC recently designed a training program in the principles of laboratory animal science and the ethical issues involved in animal use. The present study aimed to measure the effect of such training on scientists' attitudes and practice. During 4 successive training courses, the participants (n = 100; 72% women and 28% men)were surveyed twice through self-administered questionnaire-before starting and after completing the course. Questions focused on ethical consideration for care and use of animals in research, ethical committees, international guidelines for humane care of animals, and 3Rs concepts and their interpretation. The results revealed that the scientists' knowledge and awareness increased effectively after the completion of the training courses. They understood the 3Rs concepts of replacement,reduction, and refinement; recognized the importance of standardization of animal handling on scientific results; and were able to distinguish between different ethical committees and their roles. Overall, training leads to standardization of animal care and use practices that are vital for the reproducibility of results fundamental to quality scientific research.

    Abstract The present study evaluates the prophylactic role of Ananas comosus ethanolic extract (ACEE) against sodium oxalate (NaOx) - induced nephrolithiasis. Forty two rats were allocated into the following set of groups (6 rats/set group). Normal rats divided to two groups, one of them received distilled water (Control group) and the other received ACEE (1000 mg/kg body weight, p.o) for 7 consecutive days. Urolithiatic rat groups which divided into five subgroups injected with sodium oxalate (70 mg NaOx /kg body weight, i.p) for 7 days; and concurrently received oral administration of distilled water (Urolithiatic group, Vehicle), ACEE and Cystone. Interestingly, ACEE showed a beneficial effect in preventing stone formation. Significant reductions were obtained in the urinary and serum calcium and phosphate excretion along with an increase in magnesium excretion in urolithiatic rats treated with ACEE. Urolithiatic rats treated with ACEE and cystone significantly increased the urinary volume. Administration of ACEE caused significant amelioration in renal function which suggests antilithiatic activity of ACEE. Moreover, urolithiatic rats treated with ACEE significantly attenuated oxidative damage induced by NaOx. In conclusion, ACEE has antilithiatic efficacy may be due to its diuretic activity, antioxidant activity, beside its bioactive constituents which affecting calcium oxalate crystallization.

    Abstract More research is needed to understand the interactions of nanoparticles (NPs) with aquatic organisms and their mechanism of toxic action. Zinc oxide nanoparticles (ZnONPs) are the most used engineered metal oxide NPs in consumer products. The present study was designed to evaluate the cytotoxicity, genotoxicity and digestive gland (DG) as well as gill histopathology of the freshwater molluscan bivalve Coelatura aegyptiaca following exposure to ZnONPs (2, 10 and 50 mg/L) for 6 consecutive days. Exposure to ZnONPs (10 and 50 mg/L) induced a significant increase in malondialdehyde, superoxide dismutase and nitric oxide with a concomitant decrease in reduced glutathione, glutathione-S-transferase and catalase levels in the haemolymph, DG and gills of the treated mussels. Following exposure to ZnONPs (50 mg/L), the DG exhibited gradual changes in glandular activity showing hypertrophy and hyperplasia in the glandular cells and irregularity of lamellae and swelling of filaments in the gills. The present investigation revealed that oxidative stress induction, genotoxicity in the haemocytes and histological alterations in the DG and gills of C. aegyptiaca could be the main mechanisms involved in ZnONPs toxicity in aquatic organisms. Thereby, it is suggested that ZnONPs should be applied with more precautions in relevant industries, and occupational health surveillance should be necessarily considered.
