This study aimed to investigate the effects of MSG consumption on receptor gene expression and quantification of hormones and receptors, as well as oxidative stress biomarkers and other lactogenic parameters in lactating animals. Twenty-four female Wistar rats, nine weeks of age, were randomly assigned to four groups, each containing six rats, at parturition. The rats in groups II, III, and IV were given varying doses of monosodium glutamate (MSG); while, group I was given distilled water and served as the control. The experimental period lasted two (2) weeks. The groups administered with MSG showed a significant decrease in mammary PRLR gene expression (p < 0.05), as well as a marked reduction (p < 0.05) in mammary PRLR, OXT receptor, AQP-3, brain antioxidant enzymes (SOD, GPx, and CAT), and pituitary SOD compared to the control group (p < 0.05). Furthermore, there was a significant increase (p < 0.05) in reactive oxygen species levels in the serum and mammary gland homogenates, erythrocyte osmotic fragility, and elevated (p < 0.05) brain and pituitary MDA levels in the MSG-administered groups compared to the control group. Daily milk yields were significantly decreased (p < 0.05) in the MSG-administered groups between days 10 and 14 of lactation. The findings of this study suggest that prolonged consumption of MSG could interfere with lactation-associated functions via increased ROS production, reduced antioxidants, decreased AQP-3, mammary prolactin and oxytocin receptors, and prolactin receptor mRNA in lactating Wistar rats.

The aim of this plan is to perfect the methods of the means of mosquito control for an effective fight against mosquitoes in this area, known for their strong nuisance (bites) and their ability to transmit several deadly diseases. Monitoring of mosquito species in the Smir marshes, especially those of public health interest, shows that they are distributed differently in the permanent and temporary environments. The establishment and analysis of their development cycles shows that their periods of activity in the different stations of the study area overlap in several cases, especially in the permanent stations. The study of the resistance of these species to the organophosphate insecticides commonly used for mosquito control in the region allowed to conclude the doses of insecticides (LC 90) that could be used for this mosquito control programme. The proposed mosquito control programme gives an estimate of the timing of larval treatments and the insecticides that may be used. This plan was concluded based on the results obtained from the study of life cycles, spatial and temporal distribution of mosquitoes in the Smir area and their resistance to the organophosphate insecticides most used by public health services.","PeriodicalId":22591,"journal":{"name":"The Journal of Basic and Applied Zoology","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139769916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, acrylamides and their derivatives cause convulsions and diffused damage to different sections of the nervous system of infected animals. Novel copper and zinc chelates originated from (E)-3-(4-bromophenyl)-2-cyanoacrylamide (L1), and (E)-2-cyano-3-(4-nitrophenyl)acrylamide (L2) were prepared, and their chemical skeletons were identified by infrared and mass spectra. The obtained compounds were screened in vitro against the brown garden snail, Eobania vermiculata using the contact method along 72 h. Stock solutions of tested compounds were prepared utilizing distilled water and DMSO mixture, and four concentrations of each compound were prepared (50, 150, 250 and 350 ppm). Eobania vermiculata snails were treated with LC50 concentrations of prepared compounds for 3 days, and live snails were used to estimate the level of some liver and mucous secretion enzymatic biomarkers: transaminases enzymes (Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST)), Total Protein content (TP), Acid Phosphatases (ACP) and Alkaline Phosphatase (ALP). The results demonstrated that the examined compounds have a relatively toxic effect toward the screened species. Zinc complexes displayed a higher toxicity than copper ones. The results authenticated considerable high effects of the synthesized compounds on investigated enzymes. The promising effects of Cu(II), Zn(II) complexes (1, 2) on stimulating the mucous secretion of tested snails are clear through the elevated levels of ALP and ACP enzymes of treated snails. The enhancement or reduction of AST, ALT level and TP content of treated snails demonstrated the effects of prepared compounds on liver functions of these species.","PeriodicalId":22591,"journal":{"name":"The Journal of Basic and Applied Zoology","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139689914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-eight rats were divided into the following regimen’s group (24 rats/regimen). Groups I, II, III, and IV served as prophylactic groups and divided as: group I is a vehicle control received 5% DMSO (vehicle). All the remaining groups received NaOx (70 mg/kg b.wt; i.p.). Group II is NaOx lithiatic group, groups III and IV received TAEE and cystone prophylactically at doses of 500 and 750 mg/kg b.wt, respectively, since 1st day to 7th day of lithiasis stimulation. Groups V, VI, VII, and VIII served as curative groups that divided as the prophylactic ones but TAEE and cystone administered from 7th day to 14th day of lithiasis stimulation. Lithiatic rats co-/post-treated with TAEE and cystone raised the urinary volume significantly. Also, TAEE showed modulatory effect in inhibiting and curative stone creation. Significant decreases were observed in the calcium and phosphate contents in urine or serum beside the increased magnesium value in lithiatic rats co-/post-treated with TAEE. TAEE significantly ameliorates the kidney function markers, which proposes its antilithiatic role. Moreover, lithiatic rats co-/post-treated with TAEE significantly diminished oxidative injury evoked by NaOx. TAEE has antilithiatic role that may be returned to its diuretic and antioxidant activity in addition to its bioactive components including ferulic acid and phytic acid that have the inhibitory properties on crystallization calcium oxalate by lowering the content of stone promotor constituents.","PeriodicalId":22591,"journal":{"name":"The Journal of Basic and Applied Zoology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138518996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, the control of mosquito larvae is one of the best ways to avoid health problems arising from diseases transmitted by these insects. There are various control mechanisms including mechanical, biological and chemical control. The latter, despite the presence of some obstacles associated with its use, is preferred because of its ability to supply rapid management results. Result A novel laboratory-synthesized chemical compound containing pyrazole and pyridine moieties (pyrazole–pyridine derivatives, PPD) was used to control and address the biological effects on Culex pipiens mosquito second larval instar. A sublethal concentration (LC30) of PPD inhibited larval growth by about 50%. Furthermore, the developmental time of larvae into pupae and the emergence of adults from the pupal stages were increased by about 20% and 17%, respectively. The ultrastructural studies on the midgut cells revealed that treated larvae suffered dramatic degeneration in the gastric caeca and the posterior midgut cells, while the anterior midgut epithelium appeared with an abundance of lysosomal activities. Additionally, treated larvae showed fluctuated activities in the levels of the detoxifying enzymes and increased levels in total antioxidants.

SNP calling has become increasingly popular in molecular genetic studies due to their abundance and precision in estimating and identifying an organism’s genetic makeup. SNPs are versatile in trait-specific breeding, which, in contrast to pedigree breeding, is affordable and speeds up genetic advancement by allowing animals to be used as parents sooner. Results Clustering analysis revealed a strong correlation between the experimental sample, Oreochromis niloticus, Oreochromis aureus and Betta splendens . Three other species indicated evolutionary independence. Comparative genomics identified similarities between fishes with common genetic and evolutionary ancestry, allowing for better adaptation to local environmental conditions. Some of the selected genes exhibiting substantial effect on immunity include: Prxs , MMR1 like , ZMYM4-like partial ; stress-reactive genes including: PALLD-like gene, LPLBAG6-like and growth-related genes including: NF1x like , PEDF and CL like . Experimental sample, O. niloticus, O. aureas and Danio rerio , can hybridize in their natural environments bringing about genetic admixture ancestry that hybridizes new genes which confer beneficial phenotypes. Conclusion Breeding for specific traits could be a useful addition to aquaculture to allow expansion of the ecological niche and genetic base for tilapia. Some of the beneficial genes that can be hybridized include Slc25a24 and Slc12member 10 , tandem duplicate 1 , for salinity tolerance and Abca1, bcl2a and mylk13 for hypoxia tolerance. Breeders should introduce beneficial traits into fish breeds to ensure they are climate ready and able to weather climate shocks.

However, some organisms, such as Galleria mellonella larvae, have shown a unique capability to consume and degrade plastic, offering potential solutions to plastic pollution. In this study, we investigated the response of G. mellonella larvae to different diets, including artificial diet (AD), polyethylene low density mixed with AD (PELD + AD), and PELD alone. Using various microscopy techniques, we examined the larvae's hemocyte hemogram and mid-gut characteristics to understand their immune response and digestive system when exposed to plastic. Results The results revealed that PELD-only feeding negatively impacted hemocyte immunity, resulting in a significant decrease in total hemocyte counts compared to AD and AD + PELD feeding. Moreover, plastic consumption induced differential hemocyte alterations, affecting specific cell types. The presence of phagosomes in larval hemocytes and mid-gut cells during PELD-only feeding suggested active involvement in plastic breakdown. Conclusions These findings highlight the potential of G. mellonella larvae as a model organism to study responses to pollutants, emphasizing the urgent need to address plastic pollution's global threat. Further investigation is warranted to explore larval deformities, weight loss, and appetite changes, potentially influencing mortality rates and enzyme biochemistry. Understanding the impacts of plastic ingestion on G. mellonella larvae is crucial to develop effective strategies for mitigating plastic pollution's ecological implications.","PeriodicalId":22591,"journal":{"name":"The Journal of Basic and Applied Zoology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134944149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, to establish a successful mass-rearing technique, it is crucial to determine the optimal diets for larvae, pupae, and adults in terms of fecundity, longevity, and ingredient ratios. The current study aims to learn more about the biology of ladybird beetle using both artificial and natural food components. Results This study tested six different ratios of natural and artificial diets, ranging from a natural aphid diet to a variety of artificial diets containing protein hydrolyzate, casein protein, honey, dry aphids, yeast, and agar. The results showed that the natural diet (D1) produced from aphids showed approximately 290.2 eggs, while artificial diets D2 and D4 produced 56.5 and 40.2 eggs, respectively. The effect of different diets on the longevity of different life stages was also tested. The minimum longevity of egg, larval, pupal, and adult stages were recorded for D1 and D4. Furthermore, the maximum percentage emergence of larval, pupal, and adult stages was observed for D1 and D2. D6 produced the longest adult duration, with a maximum of 84.60 days. However, there was no significant difference in sex ratio among the various diet components. Conclusions In conclusion, the results suggest that artificial diets are essential for sustaining C. septempunctata cultures in laboratories, especially during periods when natural prey is scarce. The most effective and efficient mass-rearing approach would be to provide both natural and artificial foods simultaneously. These findings may have significant implications for the development of biological control strategies for aphids in agriculture.","PeriodicalId":22591,"journal":{"name":"The Journal of Basic and Applied Zoology","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136060722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
