St. Catherine is an important bird area (IBA) and declared a protectorate. In the present study, the bird community was surveyed across a gradient of different habitat types across the St. Catherine protectorate. A total of 3884 individuals belonging to 73 bird species (represented by 12 orders and 28 families) were recorded during the period from June 2017 to August 2018. The total resident bird species richness was 25 bird species with 3100 individuals in abundance belonging to 7 orders and 16 families. The most abundant resident bird species were Chukar partridge ( Alectoris chukar ), Rock Dove ( Columba livia ), Sinai Rose Finsh ( Carpodacus synoicus ), and Desert Lark ( Ammomanes deserti ). The crossing over Palearctic migratory species was higher than resident species, with a richness of 48 bird species related to 8 orders and 18 families. The top abundant migrants were White Pelican ( Pelecanus onocrotalus ), lesser whitethroat ( Sylvia curruca ), Chiffchaff ( Phylloscopus collybita ), and European honey buzzard ( Pernis apivorus ). This survey showed the importance of St. Katherine for both resident and migratory birds.

Apoptosis, along with impaired neurogenesis, has been linked to AD neurodegenerative cell death, likely due to overexpression of cyclooxygenase2 (COX-2). We investigated whether the concurrent administration of celecoxib, a selective COX-2 inhibitor, with rivastigmine, the standard anti-Alzheimer, would enhance rivastigmine anti-Alzheimer activity in the aluminum chloride (AlCl3) Alzheimer's rat model. Male rats were randomly assembled into control (Cont), AlCl3-treated (Al), rivastigmine-treated (RIVA), celecoxib-treated (Celeco), and combined rivastigmine and celecoxib-treated (RIVA+Celeco) groups. They were studied for memory, and cognitive skills, along with evaluating hippocampal acetylcholinesterase (AChE) activity. Hippocampal neuropathology, besides apoptosis, astroglial injury, and neurogenesis, were assessed through examining the expression of their related protein markers; activated caspase-3, glial fibrillary acidic protein (GFAP), and nestin. Celecoxib, rivastigmine, and their combination attenuated AlCl3induced intellectual impairment and the associated neurodegenerative changes. However, the combination therapy had no additional neuroprotective advantage over rivastigmine alone, except for the enhancement of neurogenesis and suppression of apoptosis in the AL-intoxicated rats. As compared to rivastigmine, the efficacy of celecoxib in combination with rivastigmine confers neuroprotection only at the cellular level, enhancement of neurogenesis, and suppression of apoptosis, without having a mitigating effect on Al-induced cognitive impairment.","PeriodicalId":406966,"journal":{"name":"Journal of Medical and Life Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122970637","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}

The PIK3R1 gene encodes the receptor for the p85α regulatory subunit of the phosphoinositide-3-kinase (PI3K), that involved in endothelial cell migration. The PlGF gene encodes for the placenta growth factor, a homolog of vascular endothelial growth factor (VEGFA) that is involved in angiogenesis. PIK3R1 and/or PlGF mutations may cause dysregulation of eNOS contributing to endothelial dysfunction in preeclampsia. This study aims to analyze the effect of mutation of the PIK3R1 and PlGF genes on the structure and function of PIK3R1 and PGF protein that may have an important role in pathogeneses of preeclampsia. Methodology: The data on human PIK3R1and PGF genes were retrieved from dbSNP/NCBI. Ten prediction algorithms; SIFT, PROVEAN, Polyphen, SNAP2, SNPs&GO, PANTHER PhD-SNP, I-Mutant, Mutpred, and Hope were used to analyzing the effect of nsSNPs on functions and structure of the PGF and PIK3R1 protein. STRING and KEGG databases were used for PGF and PIK3R1 protein-protein interaction. Results and Discussion:  As per the dbSNP database, the humanPIK3R1gene contained 365 missense mutations. A total 3nsSNPs (T239M, S229W, E47K) and 2 nsSNPs (H125Y, V59G) were predicted to have the most damaging effects on the structure and function of PIK3R1 and PGF respectively. STRING and KEGG revealed that PIK3R1and PGF had strong interactions with proteins involved in the VEGF signaling pathway and PI3K-Akt signaling pathway. PIK3R1 is confirmed to be linked to important diseases like preeclampsia and can affect its treatment response. Conclusion: Gene-gene interaction is an important factor in preeclampsia treatment, effect of mutation of the PIK3R1 and PlGF genes on the structure and function of PIK3R1 and PGF protein may have an important role in pathogeneses of preeclampsia. Also, these are linked to its treatment effect. This document gives formatting instructions for authors preparing papers for publication in the journal.

Exposure to Hg even in low doses can induce adverse effects on the structure and functions of the different body organs including gonads. Celery ( Apium graveolens ) leaves are rich with antioxidant compounds like apiin, apigenin, and quercetin, and vitamins like E and C. Aim: This work aimed to evaluate the possible modulatory role of celery leaves extract against gonadal toxicity induced by HgCl 2 in female rats and their pups during gestation and lactation periods. Material &methods: Twenty-four female Wistar rats (180-200g) were used in this experiment. They were mated with males. After confirmation of the gestation test, the pregnant rats were divided into four groups (six for each) as follows: control, celery extract (CE) supplement (200 mg/kg b.wt), HgCl 2 (2mg/kg b.wt) and HgCl 2 co-supplemented with CE groups. The experiment extended from the 4 th day of gestation till the end of the weaning period. At the end of weaning, the female rats and their pups were weighed and sacrificed to collect the blood and remove the gonads for estimation of biochemical and histopathological changes. Results: The obtained results revealed that exposure of female rats to HgCl 2 resulted in a significant decrease in the activities of antioxidant enzymes (SOD, CAT, and GPx) and sexual hormones (FSH, LH, estrogen, progesterone, and testosterone) in both mother rats and their pups if compared with control. Further, a light microscopic investigation revealed that exposure to HgCl2 during gestation and lactation periods induced deleterious histopathological changes in the ovaries of mothers as well as in the ovaries and testes of their offspring. Additionally, the ovarian sections from mothers and their offspring displayed weak to negative expression for calretinin antibody, however, the testicular sections from offspring appeared strongly stained with COX-2 antibody (inflammatory marker) and weakly stained with Ki67 antibody (proliferative marker). Further study by flow cytometric technique revealed a highly significant increase in the mean % value of apoptotic cells in both ovaries and testes. On the other hand, co-supplementation of CE to HgCl 2 treated group successfully alleviated the altered antioxidants and hormones as well as the histological changes near to the normal as control. Conclusion : Celery extract has a powerful ameliorative role against HgCl 2 -induced deleterious biochemical and histopathological changes in the gonads of female rats and their pups.","PeriodicalId":406966,"journal":{"name":"Journal of Medical and Life Science","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133786774","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}

This study aimed to examine the possible anti-inflammatory and antioxidant effect of AG against the damage induced by alloxan injection on renal tissue of adult male rats using histological and histochemical studies. The current experiment was carried out on 48 adult male Albino rats. Rats were randomly and equally categorized into four groups 12 rats in each group as follows: 1) Control group (C): rats have left without treatment; 2) Diabetic groups (D): rats were injected with 150 mg/kg body weight of alloxan and left for 21 days ; 3) Arabic gum groups (G): rats were orally administrated AG (25 mg/kg body weight/day) for 21 days and 4) D+G groups: rats were injected with alloxan and treated with 25 mg/kg body weight/day for 21 days. The experimental rats were sacrificed after 7 and 21 days post-treatment. Examination of renal tissue of rats seven and twenty-one days post-alloxan injection revealed many histological and histochemical changes. Highly increased collagen fibres were demonstrated after seven and twenty-one days post alloxan injection. Also, alloxan injection significantly decreased PAS-positive materials, total protein content, and total DNA content, but it significantly increased amyloid β –protein content relative to the control group. While treatment with AG post-alloxan injection showed a trend toward lowering the incidence of renal tissue histological and histochemical changes induced by alloxan injection. According to the results obtained in the current study using AG as a natural agent showed a strong cytoprotective effect against the histological and histochemical changes due to its antioxidant effect.","PeriodicalId":406966,"journal":{"name":"Journal of Medical and Life Science","volume":"16 s1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120858076","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}
