Based on well-known in vitro and in vivo models of cerebral Aβ amyloidosis, we examined the data on the effects of various natural polyphenols on the aggregation of amyloid-protein (Aβ). These polyphenols effectively prevent oligomerization and fibril formation of Aβ through differential binding patterns, lowering Aβ oligomer-induced synaptic and neuronal toxicity, according to in vitro investigations. Furthermore, in a transgenic mouse model fed orally with such polyphenolic compounds, soluble Aβ oligomers as well as insoluble Aβ deposits in the brain were significantly reduced. Natural polyphenols exhibit anti-amyloidogenic effects on Aβ, in addition to well-known anti-oxidative and anti-inflammatory activities, according to an updated assessment of the literature, implying their potential as therapeutic and/or preventive agents for AD treatment. To prove polyphenols' efficacy as disease-modifying agents, well-designed clinical trials or preventive treatments using various polyphenols are required.","PeriodicalId":433524,"journal":{"name":"Al-Rafidain Journal of Medical Sciences ( ISSN: 2789-3219 )","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125395603","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}

With an increased understanding of the pathophysiology of T2DM, various new therapeutic options have been developed and evaluated to bind different key targets in T2DM. The discovery of novel therapies through many approaches such as unprecedented drug combinations, modified drug molecules, and improved delivery systems can nullify some of the undesirable side effects of traditional agents, in addition to enhancing their effectiveness. Newer drug targets such as protein kinase B (Akt/PKB), AMP-activated protein kinase (AMPK), sirtuin (SIRT), and others are novel approaches that act via different mechanisms and possibly treating T2DMof distinct variations and etiologies. Other therapies such as end barrier, gene therapy, and stem cell technology utilize advanced techniques to treat T2DM, and the potential of these therapies is still not well explored. Molecular targets in T2DM are also extensively studied as they could target the defects at the molecular level. In this regard, antibody therapies and vaccinations are also developed against T2DM; however, the ongoing clinical trials are scanty, and the developmental progress is slower. There are many therapies designed to cure T2DM, each of them has its advantages and disadvantages. The preference for the treatment plan usually depends on the health status of the patient and the treatment goal. To consider an ideal treatment option, one should worry about many factors. These include patient compliance, drug efficacy and potency, bioavailability, and other pharmacological and non-pharmacological properties among others.","PeriodicalId":433524,"journal":{"name":"Al-Rafidain Journal of Medical Sciences ( ISSN: 2789-3219 )","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123333262","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}

Thrombocytopenia can lead to hemorrhage in vital organs, which is particularly a problematic specifically in solid cancer patients, and has a substantial negative effect on cancer patients’ quality of life (QOL). Thrombocytopenia ranges from mild bleeding from small blood vessels to severe bleeding from large blood vessels. Objectives: The present study aimed to describe the effect of chemotherapy regimens and doses on thrombocytopenia incidence and severity among solid cancer patients with thrombocytopenia. Materials and Methods: This retrospective observational study was conducted in Penang Hospital, a government hospital on Penang island, and included 341 cancer patients with thrombocytopenia who were admitted between 2003 and 2009. The main statistical tests used were the Chi-square test and logistic regression. The level of significance was set at P < 0.05. Results: Of the 341 patients included, 21 (6.2%) had thrombocytopenia before chemotherapy and the remaining 320 (93.8%) developed it after chemotherapy. The majority of patients had moderate thrombocytopenia (n=172; 53.8%), followed by mild (n=97; 30.3%), and severe thrombocytopenia (n=51; 15.9%). FEC, 5-FU+5-FU, Docetaxel and Cisplatin regimen had strong associations and correlation with thrombocytopenia incidence and severity, but the associations and correlations for thrombocytopenia severity were stronger than those for incidence. The dosage of 5-FU, cyclophosphamide, docetaxel and cisplatin plays a critical role in thrombocytopenia incidence and severity. Conclusion: Monitoring and determination of hemoglobin levels for cancer patients treated with FEC, 5-FU+5-FU, Docetaxel, and Cisplatin specifically with high doses must be emphasized and a focus of particular attention.","PeriodicalId":433524,"journal":{"name":"Al-Rafidain Journal of Medical Sciences ( ISSN: 2789-3219 )","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122240977","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}

Aims: The present study aims to investigate the impact of freezing and thawing on the glycemic response of Iraqi local white bread. Methods: In this prospective cross-over study, twelve healthy subjects (seven males, five females), aged 21–53 years, were recruited from Al-Rafidain University Campus and the local community. After overnight fasting, commercial Iraqi local white bread (200 g) was administered as fresh bread, following 1-week or 2-week freezing and thawing. Peak glucose response, 2 hr incremental area under the glucose response curve (AUC0-120) was evaluated as an outcome. Results: The different freezing and thawing conditions resulted in lower blood glucose AUC values compared to fresh white bread. In particular, compared to the fresh bread (AUC 14176±1134 mg min/dl), AUC was significantly lower when the bread was 1-week frozen and thawed (13205±660 mg min/dl, P<0.01), or 2-week frozen and thawed (12828±642 mg min/dl, P<0.01). Meanwhile, compared to the 1-week frozen bread, the 2-week freezing cycle did not produce a significantly lower AUC value.

Advanced glycation end products (AGEs) are chemical moieties produced during long-term hyperglycemia; they interact with the specific receptors for AGEs (RAGEs) and make a meaningful contribution to cellular metabolism and/or alteration of their functions. Searches in PubMed using the keywords \"advanced glycation end product \"RAGE\", \"sRAGE\", \"DM\", and \"complications” were made to reveal some of the clinical outcomes of DM in cellular metabolism and organ function through the AGE-RAGE signaling pathway. All published experimental and clinical studies were included in tables. The AGE-RAGE signaling is involved in diabetic complications such as nephropathy, neuropathy, retinopathy, and osteopathy. Some clinical results in diabetic patients could be potentially attributed to AGE-RAGE signaling consequences. However, the AGE-RAGE signaling pathway has some helpful roles in many tissues, including an increase in osteogenic function. Soluble RAGE (sRAGE), as a ligand decoy, may increase in either condition of RAGE production or destruction, and then it cannot always reflect the AGE-RAGE signaling. Although various medicines are capable to target the AGE-RAGE axis. They can also limit the associated damaging consequences. Recombinant sRAGE can block the AGE-RAGE signaling pathway; however, it is associated with some limitations such as accessibility to AGEs, increase in other RAGE ligands, and a long half-life (24 hours). It is associated with losing the beneficial effect of AGE/RAGE. As a result, sRAGE is not a helpful marker to assess the activity of the RAGE signaling pathway. The recombinant sRAGE cannot be translated into clinical practice due to its limitations.","PeriodicalId":433524,"journal":{"name":"Al-Rafidain Journal of Medical Sciences ( ISSN: 2789-3219 )","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127832408","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}
