a family history, of pre-gestational diabetes mellitus (PGDM), preeclampsia, or hypertension are at high risk of carrying a fetus with cardiac hypertrophy. These inborn developmental defects might include various cardiac defects along with fetal cardiomyopathy. Symptoms of the disease vary from minor to major and may include chest pain, as well as dyspnea. It is diagnosed based on medical history, a physical exam and echocardiogram results. Protection and treatment of the unborn fetus with cardiac hypertrophy can be achieved via lifestyle adjustment, obesity avoidance, medications and sometimes procedures. The aim of the current research is to address the etiology, diagnosis, pathogenesis and protection from cardiac hypertrophy as a teratological disorder in embryo.

This study aimed to investigate the effect of replacing corn starch in the standard diet of diabetic hypercholesterolemic rats with 3, 6 and 9% levels of honeydew melon fruit powder, peeled honeydew melon fruit powder and honeydew melon peels powder (melon fractions) on the body weight gain, insulin, organs weight, blood glucose, total cholesterol, LDL, triglyceride, kidney functions, liver functions, catalase enzyme, glutathione S-transferase enzyme and malondialdehyde. Data showed diabetes and hypercholesterolemia caused a significant increase in body weight gain, organs weight, blood glucose, total cholesterol, LDL, triglyceride, kidney functions, liver functions and malondialdehyde as well as a significant decrease in insulin, catalase enzyme and glutathione S-transferase enzyme of rats. The feeding with any level of melon fractions restored the normal liver weight and AST level in diabetic hypercholesterolemic rats to the normal values in negative control rats. Also, feeding with 9% melon fractions restored the normal body weight gain, insulin, kidney weight, heart weight, urea, creatinine, ALT, catalase enzyme, glutathione S-transferase enzyme and malondialdehyde in diabetic hypercholesterolemic rats to the normal values in negative control rats. Although glucose, total cholesterol, LDL, triglyceride, and ALP in diabetic hypercholesterolemic rats were decreased by increasing the melon fraction levels but did not return to normal values in negative control rats.

Background : Male ageing has been previously associated with declining sperm parameters, disrupted hormone secretion and increased time to pregnancy. Aging is a natural ongoing process characterized by morphological and structural degeneration and like other organs. Glucose is essential for testicular function; the uptake of carbohydrate-derived glucose by cells is mediated by glucose transporters (GLUTs). MTOR is also involved in the maintenance and restructuring of the blood-testis barrier (BTB), a key event in the seminiferous epithelium cycle Aim of the work : In the present study, we aimed to investigate the relationship between aging and the expression of GLUT2 and MTOR in the testis, the quality of the spermatogenesis process as well as the testosterone level. Materials and methods: Eighteen rats were classified into the following experimental age groups, premature, mature and aged the rats were weighed and sacrificed by decapitation under a mild dose of anesthetic ether testicular tissue was existed for histological, histochemical, immunohistochemical and molecular techniques. Results: In the aged group, Hematoxylin and Eosin stain, showed a decreased number of sperms that were observed in the lumen of seminiferous tubules, weak PAS reaction in basement membranes moderate immunohistochemical reaction for GLUT2 and MTOR antibodies, also decreased level of testosterone hormone was observed. Conclusion : spermatogenesis process is affected badly by aging that was clear histologically in testicular tissue and the decreased level of testosterone hormone.

Background : This study investigates the contamination of Polycyclic Aromatic Hydrocarbon residues in the environmental media, Malapterurus electricus , and the parasite, Electrotaenia malopteruri , in the Epe axis of the Lekki Lagoon. The paper also investigates the role of the intestinal parasite in the host-gut PAH accumulation and the effect on the gut lipid profile, anti-oxidants and histological alterations. Grab samples of surface water, sediment, fish liver, intestines and intestinal parasites were collected and analyzed for PAH residues using gas chromatography. The intestines of infected and non-infested fish and the parasite were analyzed for pathological alterations, lipid profile and antioxidant enzymes. Results : The prevalence of the cestode parasite, Electrotaenia malopteruri was 37.21%, among these infected fishes, 14 (16.28%) were females while 18 (20.93%) were males. Among PAHs congeners with 2-3 and 4-6 aromatic cyclic rings, naphthalene had the highest bio-concentration in the fish organs from the environmental media. The fish intestine bioaccumulated naphthalene 181 times more than the surface water concentrations, and 48 times more than the sediment. Other congeners that bioaccumulated in the fish intestine were fluorine, pyrene, dibenz (a,h)anthracene, dibenzo(a,l)pyrene, and benzo(g,h,i)perylene. The parasite bioaccumulated benz (a)anthracene, chrysene, benzo(a)pyrene, and benzo (g,h, i)perylene 18, 23, 3 and 2 times more than the host intestine respectively. The cholesterone, triglycerides and low-density lipid levels in Electrotaenia malopteruri were higher than that in the intestines of the infected and non-infected individuals.

Chewing lice, ticks, mites, and other ectoparasites can infect migratory birds and transmit to resident birds. Ectoparasites cause allergic reactions, irritation, anorexia, decrease in economic income, and may transmit some pathogens between birds. Our current study examined and detected ectoparasites on migratory birds in the Eastern Desert and Gabel El Zeit area, Red Sea, Egypt. During this study, we examined eighty-two migratory birds to detect ectoparasites between March 2019 and May 2022. In this period, we collect 82 newly dead migratory birds belonging to 7 orders; 36 birds of Ciconiiformes, 35 birds of Accipitriformes, four birds of Coraciiformes, two birds of Falconiformes, two birds of Pterocliformes, two birds of Suliformes, and one bird of Columbiformes were examined for ectoparasites. The collected ectoparasites from the migratory birds were preserved freezing or in 70% ethanol until identified as species in the laboratory examination. A total of twenty-six ectoparasite species were collected, belonging to 16 lice, four ticks, four flies, and two mites on migratory birds. Concluded that more studies should be conducted aimed at studying ectoparasites on all species of soaring birds migrating through Egypt.

Tetranychidae), is one of the most serious polyphagous pests worldwide. During intercropping periods, TSSM transfers to available green plants either economic or weeds. The objective of the current study was to determine the host suitability of alternative host plants. The selected promotive host plant for TSSM growth received the phytoseiid predator Typhlodromips capsicum Mostafa to feed on TSSM based on biological features and reproductive potential for prey and predator. Leaves of cheeseweed, bindweed and mint were promotive for TSSM females' longevity which lasted for 16.9, 16.3 and 16.3 days, respectively. The highest significant deposited eggs per TSSM female was recorded on cheeseweed leaves (43.6 eggs, and 3.57eggs/day) with a sex ratio of 2.6: 1 (72.25 % females). Based on TSSM longevity and fecundity, slender amaranth, groundsel, fleabane, wild oat and Jimson weed were less suitable host plants as sorted in descending order. The longevity, prey consumption and fecundity of T. capsicum females were studied on the most suitable plants for TSSM comprising rocket, parsley, mint, bindweed and cheeseweed as sorted in ascending order. The longevity of T. capsicum females on TSSM preferred plants were closely related and the highest significant prey consumption (total 75 and daily 3.95 prey individuals) reared on cheeseweed leaves accompanied by the greatest number of deposited eggs per female (total 38 eggs, and 2.54 eggs/day). The alternative host plants may play a role as a reservoir plant for phytophagous mites also provide food and habitat required for predators conservation during absence periods of major crops to keep biodiversity and natural balance.

(ZnO-NPs) used in many industries such as the food industry as additives and are a group of high crystallinity-nano particles. It is a toxic substance, especially when inhaled due to Zn2+ ion that is probably the main toxic material in vivo. The present work was planned to study the protective effect of honey on pregnant rats' livers which received ZnO-NPs and their fetal livers. The pregnant rats were divided into six groups each was 6:8 pregnant rats. The first group served as a control group and received the distilled water. The 2 nd group was administered 10 ml/kg per day of honey from the 6 th to 15 th day of gestation. The 3 rd and 4 th groups were administrated two doses of ZnONPs (10 and 50 mg/kg/day) respectively from the 6 th to 15 th day of gestation. The 5 th and 6 th groups received 10 ml/kg per day of honey before administration of ZnONPs (10 and 50 mg/kg/day). Animals of all groups received the administrated materials orally then they were sacrificed on the 20 th day of gestation. The obtained results showed an increase in the pathological changes in the liver and an increase in the changes in the liver function with the two doses of ZnONPs as compared to the normal control group. Using natural honey reduces the histopathological changes caused by ZnONPs administration.
