    Abstract In the aquatic environment, pollution with heavy metals is a major issue. Some of them are essential heavy metals because they play biological roles for aquatic organisms. Other heavy metals, however, are regarded as dangerous even at low concentrations. Heavy metal levels that are harmful may be caused by industrial, mining, and agricultural operations. Water contamination and changes to the physicochemical properties of the aquatic environment will result from this. The harmful toxic consequences of this pollution on fish raise questions about its possible impacts on human health. The most prevalent heavy metals are arsenic, cadmium, lead, and mercury, which are systemic toxicants and have an impact on human health. These metals are classified as carcinogens by the United States Environmental Protection Agency and the international agency for research on cancer because they cause organ damage even at low exposure levels. This review was created to contribute to the understanding of the environmental impact, toxicology, and consequences of heavy metals on fish.

    Abstract The growth of fraudulent pesticide trade has become a threat to farmers’ health, agrochemical businesses, and agricultural sustainability, as well as to the environment. However, assessment of the levels of farmers’ exposure to fraudulent pesticides in the literature is often limited. This paper conducted a quantitative study of farmers’ recognition and purchasing behaviors with regard to fraudulent pesticides in the Dakhalia governorate of Egypt. Using a structured questionnaire, data were collected by face-to-face interviews with 368 farmers in three districts of the governorate. The questionnaire included questions on socioeconomic characteristics, risk perception, recognition behavior, and purchasing behavior regarding fraudulent pesticides. The findings indicate that farmers perceived high risks to farmer health and crop yield (a score of 4 out of 5) and a moderate risk to the environment (3.5 out of 5) from fraudulent pesticides. Nonetheless, nearly three-fourths of the farmers had purchased fraudulent pesticides anyway. The statistical analysis suggests that farmers who resist purchasing fraudulent pesticides have higher education, longer experience in farming, and better recognition of fraudulent pesticides. To improve farmers’ ability to distinguish and avoid fraudulent pesticides, the paper recommends communication-related anti-counterfeiting measures such as awareness extension programs, as well as distribution measures in cooperation with other stakeholders.

    Abstract Meat products are essential sources of high quality animal protein, essential amino acids, and trace elements such as copper, zinc, and iron, and vitamins such as vitamin B group. However, meat products can be exposed to contamination with several xenobiotics including heavy metals. Several species of the heavy metal group have no physiological functions and their intake via contaminated food and water is associated with several adverse health effects that might reach to even death. In this review, we will throw the light on the occurrence of heavy metals and the sources of contamination of the meat products with these chemicals. Moreover, the potential adverse health effects associated with these chemicals will be reviewed.

    Abstract Minced meat is a popular meat product found mainly in most types of meat meals as a source of animal-origin food. So, it has high economic worth due to its nutritive value. Owing to the high moisture content and richness in nitrogenous composites, it is an ideal medium for bacterial growth and contamination. Synthetic preservatives are used for extending the shelf life and enhancing quality properties of meat, but consumers are only recently considering them because of worries about potential health risks. Thus, using safe natural preservatives becomes an urgent necessity. The objective of the current study aimed to determine whether cranberry essential oil (CBEO) could improve the sensory, chemical, and microbial properties of raw minced beef while also extending its shelf life.60 minced beef samples were divided into 0.0 (control), 0. 5, 1, and 1.5% CBEO treated groups. The control and treated samples were kept at 3±1ºC in the refrigerator for 12 days. Minced beef samples’ sensory, chemical, and microbial properties were evaluated every three days. The results showed that CBEO addition significantly delayed the proliferation of aerobic plate counts, psychotrophic, Staphylococcal and Enterobacteriaceae bacterial counts and extended the shelf-life of the minced beef up to 12 days compared to the control group that was completely putrefied at the 6th day of storage. This study suggested that CBEO could be used as a natural preservative for chilled minced meat.

    Abstract Objective To assess the efficacy of otoendoscopy in the surgical management of atelectatic ear to improve the clinical and the audiological outcomes. Patients and methods A total of 38 ears in 24 patients with middle ear atelectasis and intact ossicular chain were randomly assigned into two groups: group I (27 ears) underwent endoscopic T-tube insertion and group II (11 ears) underwent endoscopic cartilage tympanoplasty. Assessment of hearing was performed for all cases preoperatively and 3 months postoperatively. Results There is a significant postoperative improvement of air-bone gap averages reported in the two studied groups, with mean hearing gain of 21.67±7.97 dB in group I and 19.72±5.3 dB in group II. Conclusions At 3 months postoperatively, there was a significant statistical difference concerning different audiological parameters among the two groups.

    Abstract Vasculitis is a remarkable presentation of the extrahepatic manifestations of HCV. According to the presence or absence of cryoglobulins it is subdivided into two main types: cryoglobulinemic vasculitis and non cryoglobulinemic vasculitis based on the attribution of vasculitis to serum cryoglobulins as a pathogenic factor. The attribution of cryoglobulinemia to HCV represents a success story in the history of immunology, microbiology, and clinical medicine. HCV can bind to and invade lymphocytes, consequently triggering an immune response through different mechanisms. The epidemiology of the disease is well described and the clinical picture describes cutaneous, pulmonary, musculoskeletal, neurological, renal, endocrine, gastrointestinal, hepatic and cardiovascular manifestations. It may also be associated with sicca symptoms, an increased risk of lymphoma and serious catastrophic events. The pathology is well characterized. A classification criteria of the syndrome that was validated in 2014 is discussed. Management of CV is decided according to the presence and severity of its clinical presentation. It is divided into asymptomatic, mild, moderate, severe and life threatening disease. Recently introduced direct antiviral agents are proving safe and effective in the management of cryoglobulinemic vasculitis, and it is advocated that the two types of vasculitis be given prioritization in the Egyptian mass campaign to eradicate HCV.

    Abstract Introduction: Emergency medicine (EM) was formally recognized as a specialty in Egypt in 2002. Many institutions of higher education do not yet have an operational academic department of emergency medicine. This study attempts to quantify the awareness and attitude of Ain Shams University medical students towards emergency medicine as both a specialty and a career. Methods: A paper-based survey was delivered to undergraduate medical students at the Faculty of Medicine, Ain Shams University in Cairo, Egypt between December 2021 and April 2022. The survey was designed to assess awareness towards the scope of practice of emergency physicians as well as general attitude toward emergency medicine as a specialty and career choice. Results: A total of 391 students and interns/house officers participated in this study. 53.2% of participants were females and the mean age was 21.65 ± 2.25 years. Only 30 participants (7.7%) were classified as having “Excellent knowledge” of emergency medicine, 92 (23.5%) as “Good knowledge”, 158 “40.4%” as “Fair knowledge” and 111 (28.4%) as “Poor knowledge”. The difference in scores between academic years was not statistically significant (p = 0.239). 91.8% of respondents favored the creation of student interest groups in EM and 40% of respondents found it difficult to reach information regarding EM. Conclusion: Our study demonstrates a lack of awareness and knowledge towards emergency medicine as a specialty across all academic years at our institution. Formal recognition of EM as a specialty doesn't guarantee widespread knowledge among medical students, particularly at institutions without academic EM departments.

    Abstract From several stores and butchers in Mansoura city, Dakahlia Governorate, Egypt, 120 samples of sausage, beef burger, minced meat, luncheon, hot dog and canned meat were collected (20 each). The samples examined for detection of total mould count and identification if mould into genera and species in addition to quantification of aflatoxin B1, B2, G1 and G2. Mould detected in 100% of all examined raw meat products meanwhile, detected in 25%, 30% and 15% of examined luncheon, hotdog, and canned meat, respectively. Heat treated meat products significantly (P<0.05) contained lower mould count than raw meat products. Eight mould genera detected in all examined meat products with varying percentages in descending order Aspergillus > Penicillium > Cladosporium > Sporotricum > Alternaria > Mucor > Fusarium > Curvularia . The mean values of aflatoxin B1 were 0.78±0.21, 1.1±0. 55, 1.54±0.40, 0.052±0.032, 2.21±0.87 and 1.88±0.41 µg/kg in sausage, beef burger, minced meat, luncheon, hot dog and canned meat, respectively. Minced meat significantly lower than other examined meat products in level of aflatoxin B1(P< 0.05). Aflatoxin B2 and G2 not detected in all examined samples. The aflatoxin G1 detected in two samples of beef burger with a mean value 1.15±0.065 µg/kg and in one sample of canned meat 0.62 µg/kg. A food safety management system as hazard analysis and critical control points should be adopted by meat producers in order to protect human health.

    Abstract Meat contamination is a problem that must be addressed since it can affect consumers' health. Standard acceptable limits for heavy metals in meat and organs have been established by many international organizations. Livestock including sheep, cattle, camels, and goats side by side with other poultry species are the most significant sources of meat for protein. Heavy metal contamination in animal products may be harmful to people's health. The earth's crust naturally contains heavy metals, but uncontrolled human activity has significantly changed their geochemical cycles and biological equilibrium. This causes a buildup of metals in animal tissue that contain secondary metabolites, which gives rise to a specific pharmacological action. Humans can have negative health effects from prolonged exposure to heavy metals as lead, cadmium, arsenic, and mercury. This review showed that most of the studies conducted in different countries on heavy metals were mostly in red meat, and the research was few in the cases of domesticated birds and very rare in game birds, although it is considered a good example for investigating heavy metals in the environment

    Abstract Nanostructured ferritic (Fe (82−x) -Cr 18 -Si x , x = 0–3 wt %) and austenitic (Fe (73−x) -Cr 18 -Ni 9 -Six, x = 0–3 wt %) stainless steel (SS) alloys were developed by mechanical alloying (MA) and spark plasma sintering (SPS). The unit cell parameter estimated from X-ray diffraction spectra exhibited a decreasing trend with an increase in wt % of Si content in both alloy systems. The particle size of powders estimated using bright field transmission electron microscopy images for ferritic (3 wt % Si) and austenitic (3 wt % Si) SS powders was found to be 65 ± 5 nm and 18 ± 3 nm, respectively. In case of the ferritic system, 3 wt % Si exhibited the highest densification (~98%) and micro-hardness of about 350.6 ± 11.2 HV, respectively. Similarly, for the austenitic system (3 wt % Si), maximum densification and micro-hardness values were about 99% and 476.6 ± 15.2 HV, respectively. Comparative analysis of potentiodynamic polarization, linear polarization, and electrochemical impedance spectroscopy results indicates an increase in electrochemical performance of both alloy systems as the wt % Si was increased. The increase in electrochemical performance is directly related to the increase in densification owing to Si addition in these alloys.
