Abstract
3-nitropropionic acid (3-NP) is a potent mitochondrial inhibitor mycotoxin. Systemic administration of 3-NP can induce Huntington's disease (HD)-like symptoms in experimental animals. Safranal (Safr) that is found in saffron essential oil has antioxidant, anti-inflammatory and anti-apoptotic actions. Candesartan (Cands) is an angiotensin receptor blocker that has the potential to prevent cognitive deficits. The present study aims to investigate the potential neuroprotective efficacy of Safr or Cands in 3-NP-induced rat model of HD. The experiments continued for nine consecutive days. Rats were randomly assigned into seven groups. The first group (Safr-control) was daily intraperitoneally injected with paraffin oil. The second group (Cands- and 3-NP-control) daily received an oral dose of 0.5% carboxymethylcellulose followed by an intraperitoneal injection of 0.9% saline. The third and fourth groups received a single daily dose of 50 mg/kg Safr (intraperitoneal) and 1 mg/kg Cands (oral), respectively. The sixth group was daily treated with 50 mg Safr kg/day (intraperitoneal) and was intraperitoneally injected with 20 mg 3-NP/ kg, from the 3rd till the 9th day. The seventh group was daily treated with 1 mg Cands /kg/day (oral) and was intraperitoneally injected with 20 mg 3-NP/ kg, from the 3rd till the 9th day. The present results revealed that 3-NP injection induced a considerable body weight loss, impaired memory and locomotor activity, reduced striatal monoamine levels. Furthermore, 3-NP administration remarkably increased striatal malondialdehyde and nitric oxide levels, whereas markedly decreased the total antioxidant capacity. Moreover, 3-NP significantly upregulated the activities of inducible nitric oxide synthase and caspase-3 as well as the Fas ligand, in striatum. On the contrary, Safr and Cands remarkably alleviated the above-mentioned 3-NP-induced alterations. In conclusion, Safr and Cands may prevent or delay the progression of HD and its associated impairments through their antioxidant, anti-inflammatory, anti-apoptotic and neuromodulator effects.

Abstract
Colorectal cancer (CRC) is a major health concern with multifactorial pathophysiology representing intense therapeutic challenges. It is well known that deregulation of spatiotemporally-controlled signaling pathways and their metabolic reprogramming effects play a pivotal role in the development and progression of CRC. As such, the mitochondrial role in CRC initiation gained a lot of attention recently, as it is considered the powerhouse that regulates the bioenergetics in CRC. In addition, the crosstalk between microRNAs (miRNAs) and mitochondrial dysfunction has become a newfangled passion for deciphering CRC molecular mechanisms. This review sheds light on the relationship between different signaling pathways involved in metabolic reprogramming and their therapeutic targets, alterations in mitochondrial DNA content, mitochondrial biogenesis, and mitophagy, and the role of polymorphisms in mitochondrial genes as well as miRNAs regulating mitochondrial proteins in CRC initiation, progression, metastasis, and resistance to various therapies.

Abstract
The application of microRNAs (miRNAs) as potential biomarkers and therapy targets has been widely investigated in many kinds of cancers. Recent advantages of serum miRNAs open a new realm of possibilities for non-invasive diagnosis and prognosis of bladder cancer (BC). The aim of our study was to identify plasma miR-92a, miR-100 and miR-143 expression signatures in patients with BC to introduce new markers for establishing BC diagnosis and prognosis. Blood samples were collected from 70 BC patients and 62 controls. An expression of three target miRNAs (miR-92a, miR-100 and miR-143) was measured using quantitative real-time PCR method. Results were correlated with clinicopathological data and analysed. Plasma levels of miR-92a, miR-100 and miR-143 were significantly lower in BC patients than in control group. Receiver operator characteristic analysis revealed that the sensitivity and specificity values of miR-92a were 97·1% and 76·7%, respectively, with a cut-off value of 0·573. The sensitivity and specificity values of miR-100 were 90% and 66·7%, respectively, with a cut-off value of 0·644. The sensitivity and specificity values of miR-143 were 78·6% and 93·3%, respectively, with a cut-off value of 0·164. This study explores the existence of specific plasma miRNAs as early diagnostic biomarkers for BC in Egyptian patients; and these findings suggest that plasma miR-92a, miR-100 and miR-143 could be promising novel circulating biomarkers in clinical detection of BC.

Abstract
Diabetic peripheral neuropathy (DPN) is one of the most common diabetic chronic complications. There is an increased attention directed towards the role of angiogenic factors including vascular endothelial growth factor (VEGF) and anti-angiogenic factors including soluble endoglin (sEng) as contributors to diabetic microvascular complications including neuropathy. The purposes of this study were to determine the role of these angiogenesis regulators in the prognosis of DPN. The study group included 60 patients with type 2 diabetes mellitus (T2DM) and 20 clinically healthy individuals. The patients were divided into two groups. Group I included 20 T2DM patients without peripheral neuropathy, and Group II consisted of 40 T2DM patients with DPN. In all groups, plasma VEGF, sEng and endothelin-1 (ET-1), nitric oxide and ET-1 mRNA were estimated. Plasma levels of VEGF, sEng, ET-1 and nitric oxide were significantly elevated in diabetic patients (Groups I and II) compared with healthy control subjects, with a higher increase in their levels in patients with DPN compared with diabetic patients without peripheral neuropathy. Measurement of plasma levels of angiogenesis-related biomarkers in high-risk diabetic patients might identify who later develop DPN, thus providing opportunities for early detection and targets for novel treatments.

Abstract
Treatment of inflammatory bowel disease (IBD) by synthetic active ingredients leads to many side effects. The objective of this study was to manage IBD using natural products as curcumin and Ginkgo biloba. Rats were divided into four groups (control, IBD, curcumin treated, and ginkgo treated). Inflammation was assessed by determination of myeloperoxidase, matrix metalloproteinases, metalloproteinase-1 inhibitor, nitric oxide, hydroxyproline, tumor necrosis factor-alpha, ceruloplasmin, and histopathological scoring. IBD induction significantly increased all measured parameters. Treated groups had significantly lower levels when compared with the IBD group. In conclusion, curcumin and ginkgo were effective in prevention and treatment of IBD.

Abstract
BACKGROUND The incidence of cardiovascular disease in patients with type 2 diabetes mellitus is approximately twice as high as in the non-diabetic population. AIM To investigate the hypoglycemic and hypocholesterolemic effects of Daflon(®) 500 mg (DF) administration together with its tolerability and efficacy in reducing the cardiovascular metabolic risk factors in female patients with type 2 diabetes. METHODS In a well-adequate controlled single-blinded randomized parallel design the tolerability and the efficacy of Daflon(®) (500 mg) either alone or with oral hypoglycemic, twice daily for 45 days, was studied in 36 female patients with type 2 diabetes. RESULTS None of the patients in the studied groups were reported to have any adverse events throughout the treatment period (45 days), liver and kidney function tests were within normal limits and there was no significant difference between the pre-treatment (day 0) and post-treatment (day 45) values. Female patients receiving Daflon(®) either alone or with oral hypoglycemic showed significant decrease in serum glucose; fructosamine; total cholesterol; LDL-cholesterol; triglycerides; malondialdehydes (as index of lipid peroxidation) and C-reactive protein (CRB) levels along with increase in the levels of nitric oxide and blood glutathione. CONCLUSION This study has shown that Daflon(®) (500 mg, twice daily for 45 days) is helpful in reducing glucose level and the risk of cardiovascular disease in type 2 diabetic patients. RECOMMENDATION Further clinical trials are essential for strengthening the evidence base on the role of this drug in the cardiovascular risk in diabetic patients.
