The balance between free radicals and antioxidants is an important factor for maintaining health and slowing disease progression. The use of antioxidants, particularly natural antioxidants, has become an important strategy for dealing with this cause of widespread diseases. Natural antioxidants have been used as therapeutic tools against many diseases because they are safe, effective, and inexpensive and are among the most commonly used adjuvants in the treatment of several diseases. Camel whey protein (CWP) is considered a strong natural antioxidant because it decreases oxidative stress, enhances immune system function, and increases glutathione levels. The structure of CWP is very similar to that of other types of whey protein from different types of milk. CWP contains many components, such as lactoferrin (LF), lactalbumin, lactoglobulins, lactoperoxidase, and lysozyme, and is rich in immunoglobulins. However, in contrast to other WPs, CWP lacks β-lactoglobulin, the main cause of milk allergies in children. The components of CWP have many beneficial effects, including stimulation of both innate and adaptive immunity and anti-inflammatory, anticancer, antibacterial, and antiviral activities. Recently, it has been shown that CWP and its unique components can facilitate the treatment of impaired diabetic wound healing. However, the molecular mechanisms underlying the protective effects of CWP in human and other animal disorders are not fully understood. Therefore, the current review presents a concise summary of the scientific evidence of the beneficial effects of CWP to support its therapeutic use in disease treatment and nutritional intervention.

The goal of this study was to characterize diversity of fungal biota in soil, roots and green leaves of onion plant. Seventy- nine fungal species belonging to 32 genera were isolated from soil (29 genera and 72 species), rhizosphere (25 and 52), rhizoplane (24 and 38), phyllosphere (17 and 41) and phylloplane (17 and 35) on PDA medium at 19º and 28ºC. The number of fungal genera and species in soil was higher than those on roots and leaves, while those on the surface of roots (rhizosphere) or leaves (phyllosphere) were higher than those adhering to roots (rhizoplane) or leaves (phylloplane). Aspergillus (A. niger and A. terreus), followed by Penicillium (P. funiculosum and P. chrysogenum), Rhizopus (R. stolonifer) and Fusarium (F. oxysporum) were the most common fungi. A new record species is reported for the first time to Egypt namely, Zopfiella latipes (from phylloplane of onion).

Exposure to xenoestrogens like 4-nonylphenol (NP) is recognized by disrupting endocrine functions and causes reproductive dysfunction in male fish. The present study aimed at investigating the 4-nonylphenol propensity to induce oxidative stress and hormonal disturbances in male catfish and at studying the protective role of quince (Cydonia oblonga). To fulfill this aim, catfish Clarias gariepinus were exposed to pure 100 μg/L 4-NP and to quince the leaf extract added to 4-NP, both for 15 days. The 4-NP exposure induced a marked increase in 17ß-estradiol (E2), LH, and cortisol, while thyroid hormone (TSH, T3), testosterone (T), and FSH levels noticeably decreased; however, 4-NP had no effect on T4 level. Moreover, 4-NP exposure was accompanied by histological impairments in testes. Existence of 4-NP was associated with oxidative damage as evidenced by the significant increase (p 0.05) of the enzymes, superoxidase dismutase (SOD), catalase (CAT), acetylcholinesterase (AchE), glutathione s-transferase, total antioxidant capacity (TAC), and malondialdehyde (MDA). Adding quince was effective to neutralize hormonal levels and to repair the testicular histological alterations. In response to quince remedy, the enzymes AchE and MDA reduced significantly (p 0.05), while limited or no response was detected for other tested enzymes. Our results concluded that quince can antagonize 4-NP toxicity in catfish, confirming that quince leaf extract displayed antioxidant activities against the toxicity of hazardous chemicals.

The study of the DNA damage response in erythrocytes after g-irradiation may provide evidence for its effectiveness as a biomarkers for genotoxic environmental stress. We previously reported various malformations in erythrocytes of medaka irradiated with10 Gy, but not in their micronuclei. In this study, we optimized an assay method for g-H2AX and double strand breaks in erythrocytes of adult medaka fish after 15 Gy of g-irradiation. The highest level of apoptosis and nuclear abnormalities, including in micronuclei, were recorded 4 h after g-irradiation, as was the highest level of g-H2AX foci in erythrocytes. These results suggest that recognition and repair processes occur as a response to DNA damage in erythrocytes in medaka.
