Millions of people in the world are affected and one of the highest incidence occurred in Nigeria. The situation has been further worsened by the insufficient/ inappropriate genetic counseling and diagnosing procedure for the condition. C-reactive protein is one of the greatest indicators that can prevent patients with sickle cell disease from going into cardiac arrest if its level is determined early. This study aimed at improving knowledge on the significance of C-reactive protein as one of the indicators for a possible cardiac attack on sickle cell patients. 131 persons above 18 years of age were recruited, 95 of which were sicklecelled patients and 36 without sickle-cell used as control. Questionnaires were used to collect demographic information of the participants, while their blood samples were collected into Lithium Heparin bottle (3ml), spunned, and plasma was separated, aliquoted in 2 vials and stored at -80oC. Roche (COBAS 311) was used to analyse for C-reactive protein and data summarized in tables. Mean age was 35.4years ±SD=7.54years which ranges from 19 to 56years for sickle cell subjects, and 36.8years ±SD=9.11years which ranges from 19 to 58years for control. The male to female ratio was approximately 2:1 in control and 2.4:1 in sickle cell subjects. 2(2.1%) sickle cell patients had abnormal C-reactive protein, there is no significant difference in mean C-Reactive protein between Sickle cell patients and non-Sickle cell patients (p=.551) and there is no significant relationship between C-Reactive protein in HBSS and haematological parameters like white blood cell (p=0.622) and platelets (p=0.622). No significant disparity was determined between the sickle cell and non-sickle cell individuals. Hence, further studies are needed to confirm the factor behind the abnormal C-reative protein in the two groups.","PeriodicalId":72393,"journal":{"name":"Biomedical science and clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136100404","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 water samples were collected monthly during the monsoon and postmonsoon seasons from five sampling stations of both lakes. Comparative analysis revealed that mean pH was near the standard level in both lakes where DO concentration was much lower in Hatirjheel Lake than Dhanmondi Lake which could be due to the direct dumping of nearby residential and commercial waste, and domestic sewages from the city drainage system as well. The BOD concentration in Hairjheel Lake water exceeded the standard in both seasons and there was no significant change over seasons. In contrast, the Dhanmondi Lake water showed relatively lower BOD concentrations in both seasons where mean concentration slightly exceeded the standard in some stations. The EC and TDS contents showed positive relations but exceeded the standard limit throughout seasons in both lakes. The nutrient contents (NO3 -, NO2 - and NH4 +) of Hatirjheel Lake water highly exceeded the standard during the study that tends the lake water prone to eutrophication.

The purpose of this study was to evaluate the push-out bond strength of glass fiber posts cemented with different luting agents. The push-out bonding strength of glass fiber posts to the root canal was evaluated using resin-modified glass ionomer cement (RMGIC) and flowable composite (FC). Materials and Methods: Thirty single-rooted extracted human mandibular premolars were sectioned 2 mm coronal to the most incisal point of the cementoenamel junction. Root canals were instrumented and obturated with laterally condensed gutta-percha and root canal sealer (ADSEAL). Gutta-percha was removed from the canals to a depth of 11 mm and diameter post spaces with a 1.5 mm were prepared. The specimens were divided into the following 3 groups according to the luting agent used (n=10). The first group utilized FC (HARVARD, Germany) to coat the post, whereas the second group used RMGIC (Meron plus QM, VOCO, Germany). whereas the third group used Resin Cement (ITENA clinical, France) was used as the control. The specimens were cross-sectioned after 24 h. Specimens were cross-sectioned six millimeters thick into coronal using a sectioning machine. The strength of the bond between the luting cement and the posts was measured using push-out bond strength testing. We loaded the components at a cross speed of 0.5 mm/min on a universal testing machine until the bond failed. Results: The FC group had a 73.53N push-out bond strength, whereas the RMGIC group had a 133.55N, whereas the Resin Cement group had a 137.47N push-out bond strength. Conclusion: FC’s mean push-out bond strength score is lower than RMGIC’s and Resin Cement.","PeriodicalId":72393,"journal":{"name":"Biomedical science and clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135205417","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}

Treatment protocols varies. In our center, we have adopted the Children’s Oncology Group (COG) AHEP0731 protocol, in addition to some experimental regimens for relapsed solid tumors. Methods: We aimed to investigate the outcome of the current hepatoblastoma treatment protocol at our center. 15 patients were included between January 2008 and June 2023. A retrospective review was carried to review the clinical presentation, serum α-fetoprotein (AFP) level at diagnosis, histological subtype, treatment, and outcomes. Results: 12 patients (80%) were symptomatic at time of diagnosis, with abdominal mass being the most common presenting complaint. Nine patients (60%) presented in stage 3 PRETEXT staging system. Epithelial histopathological subtype was predominant subtype. Thirteen patients have received preoperative chemotherapy, followed by surgical resection; only one patient underwent upfront surgical resection followed by chemotherapy. Preoperative chemotherapy consists of 2 to 4 cycles of Cisplatin, Fluorouracil, Vincristine and Doxorubicin (C5VD), followed by surgical resection. Four of them underwent neoadjuvent experimental chemotherapy utilizing agents such as Pazopanib, Pembrolizumab and Sorafenib. During followup, six patients died of progressive disease. The median survival time was 42 months (95% confidence interval: 18–42%). Five-year overall survival was 44.09% (95% confidence interval: 18–42%). Conclusions: The combination of surgery and chemotherapy for hepatoblastoma is an effective approach. Utilization of new-targeted therapies and relapsed solid tumors regimens may prolong life in patients who did not respond to standard therapy. Further studies are required to validate its usage on patients with advanced hepatoblastoma.","PeriodicalId":72393,"journal":{"name":"Biomedical science and clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135746828","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 process and degree of overgrowth vary among patients, making it difficult to predict the length of the fractured femur at growth arrest. Materials and Methods 3 cases aged 4-7 years (2 boys and 1 girl) with femoral diaphyseal fractures were subjected. Observation period was 6-12 years. Leg length was assessed by taking a simple X-ray of the entire lower extremities in a standing position. Results 2 cases underwent anatomical reduction and external fixation. After the fracture had healed, there was overgrowth of the fractured femur, resulting in leg length discrepancy. Both cases were treated with an 8-plate temporal epiphysiodesis. 1 case was treated conservatively with skeletal traction, and fracture was healed with overriding of bone fragments. Overgrowth occurred and resulted in a fractured femur that became longer than opposite side. However, leg length discrepancy was gradually self-corrected and was eventually eliminated. Conclusions Overgrowth after femoral diaphyseal fracture was seen in all patients. Overgrowth tended to occur rapidly after the fracture and then slow down. Leg length discrepancy caused by overgrowth may be corrected during growth to some degree, and it should be decided whether patient need additional treatment.","PeriodicalId":72393,"journal":{"name":"Biomedical science and clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136383374","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}
