Abstract
The exceptional antioxidant properties of beetroot (BR) and the cancer antiproliferative effects of chitosan nanoparticles (CS NP) have led to the synthesis of a BR@CS nanocomposite (NC) in this study. The novel BR@CS NC was applied to human epithelial colorectal adenocarcinoma (Caco-2), human epithelial ductal breast carcinoma (T-47D), and human epithelial lung carcinoma (A549) cells. SEM characterization of CS NP revealed a variety of particle shapes ranging from 20 to 58 nm in diameter. UV-VIS analysis confirmed the formation of the BR@CS NC, while FTIR analysis demonstrated strong hydrogen bonds between CS NP and BR. These bonds reduced the positive surface charge of CS NP, as indicated by zeta potential analysis. When applied to cancer cell lines at a concentration of 250 μg/mL, the BR@CS NC successfully eradicated 89 % of A549, 88 % of T-47D, and 83 % of Caco-2 cell lines. The cell death mode exhibited extensive, apoptotic, and massive necrotic changes in all cell lines treated with BR@CS NC. Caspase 3 (CasP3) and P53 levels were elevated in BR@CS NC-treated cells. This study merges BR's antioxidant and anti-inflammatory properties with the antiangiogenic mechanism and inhibition of tumors by CS NP, resulting in a unique and innovative strategy for cancer treatment.

Abstract
Viral infections of the central nervous system (CNS) are common worldwide and result in considerable morbidity and mortality associated with neurologic illness. Until now, there have been no epidemiologic data regarding viruses causing aseptic meningitis, encephalitis, and CNS infections in Egypt. We investigated 1735 archived cerebrospinal fluid samples collected from Egyptian patients between 2016 and 2019 and performed molecular characterization for infection for12 different viruses: herpes simplex viruses 1 and 2 (HSV-1 and HSV-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), human herpesviruses 6 and 7 (HHV-6 and HHV-7), human enteroviruses (HEVs), human parechovirus (HPeV), parvovirus B19 (B19V), adenovirus (AdV), and mumps virus (MuV). All included samples were negative for bacterial infection. Our results indicated a relatively high prevalence of viral infection, with HEVs being the most prevalent viruses, followed by HSV-1, EBV, and then HSV-2. The highest prevalence was among male patients, peaking during the summer. Data obtained from this study will contribute to improving the clinical management of viral infections of the CNS in Egypt.

Abstract
OBJECTIVES Curcumin has antioxidant and antiproliferative properties, and its therapeutic effect must be considered. Nanocurcumin capsules showed a potential increase against in vitro biological cancer. This study sought to determine how curcumin nanoparticles and nanocapsules affected the expression of p53, Bcl-2, Bax, and Bax in a liver cancer cell line (Hep-G2). Mechanisms of apoptosis were also examined in this cell line. METHODS This study used quantitative real-time polymerase chain reaction (qRT-PCR) to analyze the p53, Bcl-2, Bax, and Caspase-3 gene pathways and to evaluate the molecular mechanisms responsible for the efficacy of curcumin nanoparticles (CNPs) and curcumin nanocapsules (CNCs) against liver cell lines. Flow cytometry was used to check for signs of apoptosis and the cell cycle. RESULTS Curcumin nanocapsules produced by the ball milling process at 90 min significantly boosted the populations of apoptotic cells in a dose- and time-dependent manner. The mRNA expression analysis revealed that the proapoptotic Bax, Caspase-3, and the tumor suppressor gene p53 were upregulated throughout the process started by curcumin nanocapsules and decreased in the Bcl-2/Bax ratio. CONCLUSION This research provides a fresh understanding of the molecular mechanisms behind the liver cancer-fighting abilities of curcumin nanoparticles. Curcumin nanocapsules produced through a unique mechanical technique can be used as an anticancer agent.

Abstract
Nanoparticles are considered viable options in the treatment of cancer. This study was conducted to investigate the effect of magnetite nanoparticles (MNPs) and magnetite folate core shell (MFCS) on leukemic and hepatocarcinoma cell cultures as well as their effect on the animal model of acute myelocytic leukemia (AML). Through current study nanoparticles were synthesized, characterized by various techniques, and their properties were studied to confirm their nanostructure. Invivo study, nanoparticles were evaluated to inspect their cytotoxic activity against SNU-182 (human hepatocellular carcinoma), K562 (human leukemia), and THLE2 (human normal epithelial liver) cells via MTT test. Apoptotic signaling proteins Bcl-2 and Caspase-3 expression were inspected through RT-PCR method. A cytotoxic effect of MNPs and MFCS was detected in previous cell cultures. Moreover, the apoptosis was identified through significant up-regulation of caspase-3, with Bcl-2 down-regulation. Invitro study, AML was induced in rats by N-methyl-N-nitrosourea followed by oral treatment with MNPS and MFCS. Biochemical indices such as aspartate and alanine amino transferases, and lactate dehydrogenase activities, uric acid, complete blood count, and Beta -2-microglubulin were assessed in serum. Immunophenotyping for CD34 and CD38 detection was performed. Liver, kidney, and bone marrow were microscopically examined. Bcl-2 promoter methylation, and mRNA levels were examined. Although, both MNPs and MFCS depict amelioration in biochemical parameters, MFCS alleviated them toward normal control. Anticancer activity of MNPs and MFCS was approved especially for AML. Whenever, administration of MFCS was more effective than MNPs. The present work is one of few studies used MFCS as anticancer agent.

Abstract
Using Nanoplatforms as a hauler for photosensitizers is a bespoke paradigm to improve its bioavailability and to boost the PDT efficacy. Herein, the photodynamic cytotoxicity of methylene blue (MB) loaded on hydroxyapatite nanoparticles (HA-NPs) was tested against human osteosarcoma-derived cells (Saos-2 cell line). HA-NPs and HA-NPs loaded with MB (HA-NPs-MB) were prepared by a chemical precipitation method and characterized by TEM, Zeta potential, FTIR, and XRD. TEM images revealed that HA-NPs have a rod shape with a diameter of 14-17 nm and length around 46-64 nm. FTIR and Zeta potential confirmed the adsorption of cationic MB on HA-NPs. XRD pattern was identical to the standard XRD pattern of HA-NPs. Incubation of Saos-2 cells (24 h) with HA-NPs-MB then irradiation of cells (5 min) with a diode laser (808 nm), causes a higher decrement of cell viability (determined by MTT assay) than that caused by free MB. The LC50 was 57.53 µg/mL and 86.99 µg/mL for HA-NPs-MB and free MB, respectively. Thus, the nanoformulation of MB greatly reduced the dose of MB required for effective PDT. This study also investigated the mode of cell death after incubation of cells with free MB or HA-NPs-MB composite then exposure to laser radiation. The results revealed that the majority of cells died by apoptosis while a minor fraction of cells died by necrosis, especially in the case of HA-NPs-MB. Levels of caspase-3 and death receptor-4 (DR-4) were more elevated in the case of HA-NPs-MB than free MB. The effect of the prepared nanocomposite and free MB on Raw murine macrophage (RAW 264.7) viability was also examined using the MTT assay. The results indicated that HA-NPs-MB in the presence of laser has a great cytotoxic effect on macrophage cells compared to other treatments. This may present an advantage through decreasing macrophage that promotes tumor growth. In conclusion, HA-NPs-MB nanocomposite surmounts free MB and HA-NPs in destroying macrophage cells and Saos-2 cells through apoptosis in the presence of laser irradiation. This study introduces a thorough and new insight on osteosarcoma (cancer cell line Saos-2) PDT using HA-NPs-MB exploiting the biosafety of HA-NPs.

Abstract
Introduction Venous thromboembolism (VTE) requires urgent diagnosis and treatment to avoid related complications. Clinical presentations of VTE are nonspecific and require definitive confirmation by imaging techniques. A clinical pretest probability (PTP) score system helps predict VTE and reduces the need for costly imaging studies. d-dimer (DD) assay has been used to screen patients for VTE and has shown to be specific for VTE. The combined use of PTP and DD assay may improve exclusion of VTE and safely avoid imaging studies. Materials and methods We prospectively used the Wells PTP score and a DD test to evaluate 230 consecutive patients who presented with VTE symptoms. The receiver operating characteristic curve was used to identify a new DD cutoff value, which was applied to VTE diagnosis and compared with the upper limit of locally established reference range for prediction of thrombosis alone and in combination with the clinical PTP score. Results We evaluated 118 patients with VTE symptoms fulfilling the inclusion criteria, 64 (54.2%) with clinically suspected deep vein thrombosis (DVT) and 54 (45.8%) with symptoms of pulmonary embolism (PE). The PTP was low in 28 (43.8%) and moderate/high in 36 (56.25%) of the suspected DVT patients, and low in 29 (53.7%) and moderate/high in 25 (46.3%) of the suspected PE patients. Eighteen cases were confirmed by imaging studies: 9 DVT and 9 PE. The agreement between confirmed cases and PTP was significant with PE but not DVT. The negative predictive value for both DVT and PE with current DD cutoff value of <250 μg/L DDU was 100%, whereas with the calculated cutoff the NPV was 88%. Conclusions We confirm that PTP score is valuable tool for medical residents to improve the detection accuracy of VTE, especially for PE. The DD cutoff value of 250 μg/L FEU is ideal for excluding most cases of low PTP; however, the calculated cutoff was less specific for the exclusion of VTE.

Abstract
INTRODUCTION The aim of this study was to determine the clinical outcome of lower limb arterial angioplasty in a busy district general hospital practice. PATIENTS AND METHODS All angioplasties performed from January 1999 to December 2004 were identified and data collected included cardiovascular risk factors, indications for and complications of angioplasty, limb salvage and patient survival rates, and clinically significant re-stenoses. RESULTS 471 interventions were performed in 385 patients (231 men, 154 women). The median age was 67.9 years (range: 39-93 years). Indications for angioplasty were critical ischaemia (n=247, 52%) and lifestyle-limiting intermittent claudication (n=224, 48%). Stenotic lesions accounted for 378 (80%) cases and occlusion for 93 (20%). Radiological success was obtained in 417 (88.5%), improving to 93.6% if only those in whom access was achieved were included. Post-angioplasty complications were observed in 42/471 (9.1%) of interventions. The actual patient survival at 1, 2, and 3 years was 87.4%, 85.1% and 83.2% respectively. Indication for angioplasty and the number of lesions present were identified as risk factors for outcome on multivariate analysis. The cumulative post-angioplasty patency rates at 1, 2 and 3 years were 86.0%, 83.1% and 81.6% respectively. The only factor associated with patency was the mode of presentation. CONCLUSIONS Angioplasty for lower limb peripheral vascular disease can be performed safely and efficaciously with a high technical success rate and a low complication rate. The patient survival and post-angioplasty patency data reflect the progressive and multi-site nature of the underlying disease process.

Abstract
Postmenopausal osteoporosis and osteoporosis in elderly men are major health problems, with a significant medical and economic burden. Although osteopenia and osteoporosis are more common locally than in the West, fracture rates are generally less than in Western countries. Vitamin D deficiency is common in the region and contributes adversely to bone health. Vitamin D deficiency should be suspected and treated in all subjects with ostopenia or osteoporosis. The use of risk factors to determine fracture risk has been adopted by the World Health Organization and many international societies. Absolute fracture risk methodology improves the use of resources by targeting subjects at higher risk of fractures for screening and management. The King Faisal Specialist Hospital Osteoporosis Working Group recommends screening for women 65 years and older and for men 70 years and older. Younger subjects with clinical risk factors and persons with clinical evidence of osteoporosis or diseases leading to osteoporosis should also be screened. These guidelines provide recommendations for treatment for postmenopausal women and men older than 50 years presenting with osteoporotic fractures for persons having osteoporosis-after excluding secondary causes-or for persons having low bone mass and a high risk for fracture. The Working Group has suggested an algorithm to use at King Faisal Specialist Hospital that is based on the availability, cost, and level of evidence of various therapeutic modalities. Adequate calcium and vitamin D supplement are recommended for all. Weekly alendronate (in the absence of contraindications) is recommended as first-line therapy. Alternatives to alendronate are raloxifene or strontium ranelate. Second-line therapies are zoledronic acid intravenously once yearly, when oral therapy is not feasible or complicated by side effects, or teriparatide in established osteoporosis with fractures.

Abstract
OBJECTIVE Colorectal cancer (CRC) is more common in developed countries and is the third most common cancer among both men and women. CRC provides an attractive model of tumour biology with normal mucosa to adenoma to carcinoma sequence. The TF-antigen (Thomsen-Friedenreich) can be identified by galactose oxidase-Schiff's (GOS) reaction either on tissues or on rectal mucus samples from patients with CRC. TF antigen is expressed in the neoplastic mucosa and not expressed in colonic mucosa of normal subjects. Apomucins play important role in cell signalling and their specific pattern of expression during the different steps of tumor progression toward adenocarcinoma suggests that they play significant roles in tumorigenesis. The family of secreted mucins including MUC2 is contributing in mucus formation to protect underlying epithelia against diverse injuries. The current study was investigated the expression of MUC2 and TF antigens in patients with adenoma and CRC. MATERIALS AND METHODS MUC2 and TF antigen expressions were detected immunohistochemically in CRC biopsies using specific monoclonal antibodies. Moreover, the TF antigen was invesigated using GOS reaction. RESULTS The results showed that in normal colonic specimens, MUC2 expression was detected in 20%, while TF antigen was completely negative in 100% of samples as detected by GOS and immunohistochemistry using anti-TF monoclone. Expressions of MUC2, and TF antigen as detected by GOS and anti-TF monoclone were positive in 96%, 80%, and 60% respectively in cases with adenoma. On the other hand, in cases with adenocarcinoma, the expression of MUC2 was seen in 92% of cases, while TF antigen was observed in 84% and 60% of cases as detected by GOS and immunohistochemically respectively. CONCLUSIONS Thus, it is concluded that the expression of MUC2 and TF antigens are altered during CRC carcinogenesis. Furthermore, MUC2 and TF antigens may have a diagnostic and or prognostic potential in CRC.

Abstract
Objective: To report a case of rosiglilazone-associated hepatotoxicity in a patient with Hodgkin's lymphoma. Case Summary: A 52-year-old man presented with low-grade fever and fatigue that had been present for 4 months. He had been receiving insulin for 5 years and rosiglitazone 4 mg/day for 11 months for control of type 2 diabetes; he was receiving no other drug therapy. During hospitalization, hepatotoxicity was shown, with abnormal liver function test results including alanine aminotransferase 488 U/L, aspartate aminotransferase 344 U/L, alkaline phosphatase B32 U/L, total bilirubin 4.61 mg/dL, and direct bilirubin 3.63 mg/dL. Rosiglitazone was discontinued after further elevation of bilirubin (total 14.67 mg/dL, direct 12.10 mg/dL) occurred. Other causes for hepatotoxicity were ruled out, Hodgkin's lymphoma was diagnosed during the workup; however, liver imaging and biopsy also excluded this as the direct cause of acute liver failure. Despite discontinuation of rosiglitazone, the bilirubin level continued to increase to 49.29 mg/dL (direct >20 mg/dL). The patient died 3 months after admission. Discussion: Rosiglitazone maleate is a thiazolidinedione approved for treatment of type 2 diabetes mellitus. The first member of this drug class, troglitazone, was withdrawn from the market due to reports of acute liver failure. Rosiglitazone has been shown to be much safer than troglitazone, despite some reported cases of early-onset nonfatal hepatotoxicity. Use of the Naranjo probability scale indicated that rosiglitazone was the probable cause of acute liver failure in our patient. Conclusions: We conclude that rosiglitazone may be associated with late-onset acute liver failure. Clinicians should be aware of such a complication and monitor liver function in patients receiving the drug.

Abstract
A 63-year-old male underwent emergency repair of a ruptured juxtarenal aortic aneurysm via a transabdominal approach using an aorto-bi-iliac Dacron graft. This became infected. A right axillobifemoral bypass was placed and the infected graft was removed with oversewing of the aorta. The patient was re-admitted 8 months later with an infected axillobifemoral prosthesis. We harvested both femoral veins (FV) and spliced them to perform a left thoracobifemoral bypass with simultaneous explantation of the infected graft. The patient remains well with a patent graft 20 months post-operatively.

Abstract
Most cases of splenic artery aneurysm are asymptomatic, being found incidentally at the time of investigations (e.g. ultrasound, computed tomography, angiography) or laparotomy for other conditions. Rupture of a splenic artery aneurysm with erosion into the stomach is a rare cause of massive upper gastrointestinal haemorrhage. This case report is, to our knowledge, only the second case of splenic artery aneurysm presenting with massive upper gastrointestinal haemorrhage due to erosion into the stomach in a nulliparous woman.
