Abstract
The bacterium Natranaerobius thermophilus is an extremely halophilic alkalithermophile that can thrive under conditions of high salinity (3.3-3.9 M Na+), alkaline pH (9.5), and elevated temperature (53°C). To understand the molecular mechanisms of salt adaptation in N. thermophilus, it is essential to investigate the protein, mRNA, and key metabolite levels on a molecular basis. Based on proteome profiling of N. thermophilus under 3.1, 3.7, and 4.3 M Na+ conditions compared to 2.5 M Na+ condition, we discovered that a hybrid strategy, combining the "compatible solute" and "salt-in" mechanisms, was utilized for osmotic adjustment dur ing the long-term salinity adaptation of N. thermophilus. The mRNA level of key proteins and the intracellular content of compatible solutes and K+ support this conclusion. Specifically, N. thermophilus employs the glycine betaine ABC transporters (Opu and ProU families), Na+/solute symporters (SSS family), and glutamate and proline synthesis pathways to adapt to high salinity. The intracellular content of compatible solutes, including glycine betaine, glutamate, and proline, increases with rising salinity levels in N. thermophilus. Additionally, the upregulation of Na+/ K+/ H+ transporters facilitates the maintenance of intracellular K+ concentration, ensuring cellular ion homeostasis under varying salinities. Furthermore, N. thermophilus exhibits cytoplasmic acidification in response to high Na+ concentrations. The median isoelectric points of the upregulated proteins decrease with increasing salinity. Amino acid metabolism, carbohydrate and energy metabolism, membrane transport, and bacterial chemotaxis activities contribute to the adaptability of N. thermophilus under high salt stress. This study provides new data that support further elucidating the complex adaptation mechanisms of N. thermophilus under multiple extremes.IMPORTANCEThis study represents the first report of simultaneous utilization of two salt adaptation mechanisms within the Clostridia class in response to long-term salinity stress.

Abstract
Breast cancer is the most common type of cancer in Egyptian females. Polymorphisms in the angiogenesis pathway have been implicated previously in cancer risk and prognosis. The aim of the current study was to determine whether certain polymorphisms in the genes of vascular endothelial growth factor A (VEGFA), vascular endothelial growth factor receptor 2 (VEGFR2), vascular endothelial growth inhibitor (VEGI), and hypoxia-inducible factor-1α (HIF1A) associated with breast cancer development. The study included 154 breast cancer patients and 132 apparently healthy age-matched females as a control group. VEGFA rs25648 genotyping was performed using (ARMS) PCR technique; while VEGFR2 rs2071559, VEGI rs6478106, and HIF-1α rs11549465 were genotyped by the PCR-RFLP method. Serum levels of VEGF, VEGFR2, VEGI, and HIF1A proteins in breast cancer patients and controls were measured by ELISA. There was a significant association between the VEGFA rs25648 C allele and breast cancer risk (OR 2.5, 95% CI 1.7-3.6, p < 0.001). VEGFA rs25648 C/C genotype was statistically significantly higher in breast cancer patients vs. control (p < 0.001). Participants with the T/T and T/C VEGFR2 rs2071559 genotypes had 5.46 and 5 higher odds, respectively, of having breast cancer than those with the C/C genotype. For the VEGI rs6478106 polymorphism, there was a higher proportion of C allele in breast cancer patients vs. control (p = 0.003). Moreover, the C/C genotype of VEGI rs6478106 was statistically significantly higher in breast cancer patients vs. control (p = 0.001). There was no significant difference in genotypes and allele frequencies of HIF1A rs11549465 polymorphism between breast cancer cases and control individuals (p > 0.05). Serum levels of VEGFA, VEGI, and HIF1A were considerably greater in women with breast cancer than in the control (p < 0.001). In conclusion, the genetic variants VEGFA rs25648, VEGFR2 rs2071559, and VEGI rs6478106 revealed a significant association with increased breast cancer risk in Egyptian patients.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is a chronic progressive disease due to insulin resistance. Oxidative stress complicates the etiology of T2DM. Saxagliptin is a selective dipeptidyl peptidase-4 (DPP-4) inhibitor, while Pioglitazone is a thiazolidinedione insulin sensitizer. This study aimed to assess the effect of Saxagliptin and Pioglitazone monotherapy and combination therapy on the biochemical and biological parameters in streptozotocin (STZ)-induced diabetic rats. METHODS The study included thirty-five male albino rats. Diabetes mellitus was induced by intraperitoneal STZ injection (35 mg/kg). For a 1-month duration, rats were divided into five groups. Glucose homeostasis traits, lipid profiles, kidney functions, liver enzymes, and oxidative stress markers were measured. Gene expression of miRNA-29a, phosphoenolpyruvate carboxykinase (PEPCK), phosphoinositide-3-kinase (PI3K), and interleukin 1 beta (IL-1β) was assessed using qRT-PCR. RESULTS At a 1-month treatment duration, combination therapy improves oxidative stress markers more than either drug alone. The combination therapy had significantly higher levels of SOD, catalase, and GSH and lower levels of MDA compared to the monotherapy. Additionally, the diabetic group showed a significant increase in the expression levels of miRNA-29a, PEPCK, and IL-1β and a significant decrease in PI3K compared to the normal control group. However, combination therapy of Saxagliptin and Pioglitazone was more effective than either Saxagliptin or Pioglitazone alone in reversing these results, especially for PEPCK and IL-1β. CONCLUSIONS Our findings revealed that combining Saxagliptin and Pioglitazone improves glycemic control and genetic and epigenetic expression profiles, which play an essential regulatory role in normal metabolism.

Abstract
INTRODUCTION Chronic inflammation causes articular bone and cartilage degeneration in people with rheumatoid arthritis (RA). Despite recent advancements in the management of RA, adverse side effects and ineffective treatments remain a problem. Effective treatment is usually hampered by financial issues. As a result, less expensive medications that reduce both inflammation and bone resorption are required. Mesenchymal stem cells (MSCs) have recently been identified as a potential therapy for RA. AIM OF THE STUDY This study aimed to examine the anti-arthritic effect of rat bone marrow-derived mesenchymal stem cells (rBM-MSCs), oligosaccharides (Os), and human placental extract (HPE), individually and combined, on an RA model, using Complete Freund's adjuvant (CFA)-induced arthritis in rats. MATERIALS AND METHODS In female rats, RA was induced by injecting CFA in the paw of the hind limb. Rat bone marrow-MSCs, oligosaccharides, and human placental extract (HPE) were given individually and in combination via the intraperitoneal route. A complete blood count (CBC), erythrocyte sedimentation rate (ESR), serum cortisol, urea, uric acid, and other biochemical parameters were measured to determine the safety and efficacy of the different treatments. Histopathological analysis of bone sections was carried out. RESULTS Combining oligosaccharides and HPE therapy with the infusion of rat-bone marrow MSCs had beneficial antiarthritic and anti-inflammatory effects in CFA-induced arthritis in rats: overall such triple therapy significantly reduced serum levels of IL-6, IL-10, and TNF-alpha in comparison with all other combinations (all P > 0.05). Meanwhile, the triple therapy did not have negative effects on levels of CBC, serum cortisol, ESR, and liver enzymes (all NS) as well as on renal functions (NS). Also, the histopathological analysis showed significant improvements in the healing and remodelling of osteoporotic lesions in arthritic rats. As shown by counting apoptotic cells as a histopathological substitute for measuring apoptotic or regeneration markers, the lowest count was found in the group treated with a triple therapy of rat bone marrow-derived mesenchymal stem cells (rBM-MSCs), oligosaccharides, and HPE. CONCLUSION The combination of rat MSCs, oligosaccharides, and HPE has the potential to be an effective treatment for rheumatoid arthritis.

Abstract
The moderate halophilic bacterium Alkalicoccus halolimnae BZ-SZ-XJ29T exhibits optimum growth over a wide range of NaCl concentrations (8.3-12.3%, w/v; 1.42-2.1 mol L-1 ). However, its adaptive mechanisms to cope with high salt-induced osmotic stress remain unclear. Using TMT-based quantitative proteomics, the cellular proteome was assessed under low (4% NaCl, 0.68 mol L-1 NaCl, control (CK) group), moderate (8% NaCl, 1.37 mol L-1 NaCl), high (12% NaCl, 2.05 mol L-1 NaCl), and extremely high (16% NaCl, 2.74 mol L-1 NaCl) salinity conditions. Digital droplet PCR confirmed the transcription of candidate genes related to salinity. A. halolimnae utilized distinct adaptation strategies to cope with different salinity conditions. Mechanisms such as accumulating different amounts and types of compatible solutes (i.e., ectoine, glycine betaine, glutamate, and glutamine) and the uptake of glycine betaine and glutamate were employed to cope with osmotic stress. Ectoine synthesis and accumulation were critical to the salt adaptation of A. halolimnae. The expression of EctA, EctB, and EctC, as well as the intracellular accumulation of ectoine, significantly and consistently increased with increasing salinity. Glycine betaine and glutamate concentrations remained constant under the four NaCl concentrations. The total content of glutamine and glutamate maintained a dynamic balance and, when exposed to different salinities, may play a role in low salinity-induced osmoadaptation. Moreover, cellular metabolism was severely affected at high salt concentrations, but the synthesis of amino acids, carbohydrate metabolism, and membrane transport related to haloadptation was preserved to maintain cytoplasmic concentration at high salinity. These findings provide insights into the osmoadaptation mechanisms of moderate halophiles and can serve as a theoretical underpinning for industrial production and application of compatible solutes.

Abstract
BACKGROUND Colorectal cancer (CRC) is a common tumor worldwide. CRC is influenced by several types of miRNAs and long non-coding RNAs. This study aims to evaluate the correlation of lncRNA ZFAS1/ miR200b/ ZEB1 protein with presence of CRC. METHODS Quantitative real-time polymerase chain reaction was used to measure serum expression of lncRNA ZFAS1 and microRNA-200b in 60 CRC patients and 28 control subjects. ZEB1 protein in serum was measured by ELISA. RESULTS Lnc ZFAS1 and ZEB1 were up-regulated in CRC patients in compare to control subjects while miR-200b was down-regulated. There was a linear correlation between ZAFS1 expression and miR-200b and ZEB1 in CRC. CONCLUSION ZFAS1 is a key player of CRC progression and could be a potential therapeutic target by sponging miR-200b. In-addition the association between ZFAS1, miR-200b and ZEB1 highlights their potential value as a novel diagnostic biomarker in human CRC.

Abstract
Carpal tunnel syndrome (CTS) is a common entrapment neuropathy in which one of the body's peripheral nerves becomes pinched or crushed. Transforming growth factor beta 1 (TGF-β1) plays an important role in the pathogenesis of CTS. An association between TGF-β1 polymorphisms and the susceptibility or progression of a number of diseases has been reported. In this study, three TGF-β1 single nucleotide polymorphisms (SNPs), serum TGF-β1, and macrophage inflammatory protein 1 beta (MIP-1β) were investigated as potential diagnostic markers for the progression of CTS in Egyptian patients. One hundred CTS patients and 100 healthy controls were recruited for the study. TGF-β1 SNPs +915G/C, -509C/T and -800G/A were determined by TaqMan genotyping assay. Serum TGF-β1 and MIP-1β levels were measured by ELISA. Serum TGF-β1 and MIP-1β levels increased significantly and were strongly correlated with the occurrence of CTS. The C allele of +915G/C, the T allele of -509C/T, and the G allele of -800G/A occurred more frequently in patients from CTS than in controls. The serum levels of TGF-β1 and MIP-1β in the group of carriers of the genotypes +915G/C GC and CC, the genotype -509C/T TT and the genotype -800G/A GA and AA were significantly higher in CTS patients. TGF-β1 and its +915G/C, -509C/T, and -800G/A SNPs and MIP-1β could be useful prognostic markers for the occurrence of CTS.

Abstract
Droplet digital PCR (ddPCR) is being increasingly adopted for gene detection and quantification because of its higher sensitivity and specificity. According to previous observations and our laboratory data, it is essential to use endogenous reference genes (RGs) when investigating gene expression at the mRNA level under salt stress. This study aimed to select and validate suitable RGs for gene expression under salt stress using ddPCR. Six candidate RGs were selected based on the tandem mass tag (TMT)-labeled quantitative proteomics of Alkalicoccus halolimnae at four salinities. The expression stability of these candidate genes was evaluated using statistical algorithms (geNorm, NormFinder, BestKeeper and RefFinder). There was a small fluctuation in the cycle threshold (Ct) value and copy number of the pdp gene. Its expression stability was ranked in the vanguard of all algorithms and was the most suitable RG for quantification of expression by both qPCR and ddPCR of A. halolimnae under salt stress. Single RG pdp and RG combinations were used to normalize the expression of ectA, ectB, ectC and ectD under four salinities. The present study constitutes the first systematic analysis of endogenous RG selection for halophiles responding to salt stress. This work provides a valuable theory and an approach reference of internal control identification for ddPCR-based stress response models.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a joint destructive disorder. This study aimed to assess lncRNA MEG3 expression and its variant rs941576 in Egyptian patients with RA. SUBJECTS AND METHODS 100 RA patients and 100 healthy individuals were enrolled in the study. Quantitative PCR was used for expression analysis and allelic discrimination technology for genotyping. RESULTS LncRNA MEG3 was down-regulated in RA patients and negatively associated with RA clinical features and HIF-1α and VEGF serum levels. On the contrary, it was positively associated with BAX serum levels in RA patients. The major A allele of rs941576 variant was associated with RA patients (p = .0003). AA genotype showed a significant decrease in lncRNA MEG3 expression and BAX and increase in HIF-1α and VEGF. CONCLUSIONS Serum lncRNA MEG3 expression showed negative association with increased susceptibility to RA. MEG3 gene rs941576 (A/G) polymorphism was associated with increased severity of RA in the current population.

Abstract
CONTEXT ZNF804a and CDK1 genes code for proteins involved in inflammatory pathways. OBJECTIVE This study aimed to investigate the correlation of ZNF804a and CDK1 expression profiles in RA with the activity and the severity of the disease and to assess their association with inflammatory reactions in the Egyptian RA patients. METHODS ZNF804a and CDK1 expression profiles were assessed using quantitative PCR (qRT-PCR). Clinical and laboratory parameters were evaluated. RESULTS ZNF804a expression was down-regulated by 0.177-fold while CDK1 expression was up-regulated to 3.29-fold in RA patients compared with healthy controls (p < .001). ZNF804a down-regulation was negatively correlated with CRP, RF, disease activity score of 28 joints (DAS) using CRP (DAS-CRP) and TNF-α. CDK1 overexpression was correlated with IFN-1 and ACPA in RA patients. CONCLUSION ZNF804a and CDK1 genes are implicated in RA pathogenesis due to their influences on TNF-α and IFN-1 which contribute to inflammation in RA patients.

Abstract
AIMS The first-line treatment for advanced hepatocellular carcinoma (HCC) is the multikinase inhibitor sorafenib (SOR). Sofafenib resistance is linked to protein kinase B/ mammalian target of rapamycin (AKT/mTOR) and nuclear factor kappa B (NF-κB) activation, apoptosis inhibition and oxidative stress. This study investigated selenium nanoparticles (SeNps) to overcome SOR resistance in thioacetamide (TAA) induced HCC in rats. MATERIALS AND METHODS TAA (200 mg/kg/twice weekly, i.p.) was administered for 16 weeks to induce HCC.s. Rats were treated with oral SOR (10 mg/Kg daily), selenium, and SeNps (5 mg/kg three times/week) alone or in combination, for two weeks. Apoptosis, proliferation, angiogenesis, metastasis and drug resistance were assessed. Cleaved caspase 3 (C. CASP3), mTOR, and NF-κB were determined by western blotting. Expression of p53 gene and long-noncoding RNA-AF085935 was determined by qRT-PCR. Expression of B- Cell Leukemia/Lymphoma 2 (Bcl2), Bcl associated X protein (Bax)and glypican 3 (GPC3) was determined by enzyme-linked immunosorbent assay. Liver functions, antioxidant capacity, histopathology and CD34 immunohistochemistry were performed. KEY FINDINGS SOR/SeNps reversed TAA-induced HCC in rats, through reduction of oxidative stress, activation of p53, Bax and CASP3, and inhibition of Bcl2. SOR/SeNps ameliorated the HCC-induced effect on cell proliferation and drug resistance by targeting mTOR and NF-κB pathways. SOR/SeNps decreased CD34 immunostaining indicating a decrease in angiogenesis and metastasis. SOR/SeNps regulated HCC epigenetically through the lncRNA-AF085935/GPC3 axis. SIGNIFICANCE SOR/SeNps are a promising combination for tumor suppression and overcoming sorafenib resistance in HCC by modulating apoptosis, AKT/mTOR and NF-κB pathways, as well as CD34 and lncRNA-AF085935/GPC3 axis.

Abstract
Biocatalysis is crucial for a green, sustainable, biobased economy, and this has driven major advances in biotechnology and biocatalysis over the past 2 decades. There are numerous benefits to biocatalysis, including increased selectivity and specificity, reduced operating costs and lower toxicity, all of which result in lower environmental impact of industrial processes. Most enzymes available commercially are active and stable under a narrow range of conditions, and quickly lose activity at extremes of ion concentration, temperature, pH, pressure, and solvent concentrations. Extremophilic microorganisms thrive under extreme conditions and produce robust enzymes with higher activity and stability under unconventional circumstances. The number of extremophilic enzymes, or extremozymes, currently available are insufficient to meet growing industrial demand. This is in part due to difficulty in cultivation of extremophiles in a laboratory setting. This review will present an overview of extremozymes and their biotechnological applications. Culture-independent and genomic-based methods for study of extremozymes will be presented.

Abstract
Hepatocellular carcinoma (HCC) is the most common form of malignancy in the liver. Autophagy was found to have a significant effect in controlling HCC. Anthocyanins, which are naturally occurring pigments in a variety of fruits and vegetables, have been thoroughly documented to be involved in a variety of bioactive activities and are widely employed for their antioxidant capabilities. Cyanidin-3-glucoside (C3G) extracted from Morus alba L. has promising antioxidant and anti-tumour activities. The current study aims to examine the protective action of C3G against hepatocellular carcinoma through the investigation of the autophagy protein ATG16L1 expression along with its related RNA molecules (hsa_circ_0001345 and miRNA106b) in Wistar rats. In vivo precancerous lesions (PCL) were induced using diethylnitrosamine (DEN) and acetamidofluorene (2-AAF). Rats were treated with C3G (10, 15, and 20 mg/kg; 4 times weekly) for 112 days (16 weeks). Liver function tests, alfa fetoprotein, ATG16L1 expression, hsa_circ_0001345, and miRNA106b differential expression were examined. Liver sections were examined by histological and immunohistochemical approaches. The current study’s findings indicated that C3G administration protects against the negative effects of DEN-2-AAF on liver functions and liver histopathological sections, which nominated C3G as a potential prophylactic agent against HCC.

Abstract
BACKGROUND AND AIMS Currently, liver biopsy is the gold standard method for diagnosis of non-alcoholic fatty liver severity. It is critical to develop non-invasive diagnostic method to diagnose nonalcoholic fatty liver rather than invasive techniques. Our case-control study was to address the value of circulating miRNA-122 and serum pro-neurotensin as a potential non-invasive biomarker for the diagnosis of non-alcoholic fatty acid diseases. METHODS Clinical assessment, laboratory investigations, and anthropometric measurements were reported for 157 patients with proven NAFLD. Apparently, healthy participants (n=100) were enrolled as a control group. Serum samples were tested for micro-RNAs-122 and pro-neurotensin. RESULTS Compared with the control subjects, both mi-RNA-122 and serum proneurotensin levels were increased in NAFLD (p<0.001) and at a cut-off ≥6.83, mi-RNA-122 had 51.0% sensitivity, 70.0% specificity to differentiate NAFLD from healthy controls, while serum proneurotensin had 80.0% sensitivity and 80.0% specificity at a cutoff ≥108. CONCLUSION The circulating pro-neurotensin might be used as a novel biomarker for diagnosis of patients with NAFLD, wherefore the integration of a circulating mi-RNA-122 and serum pro-neurotensin could be beneficial to diagnose NAFLD cases. Large-scale studies are needed to investigate the possible role of mi-RNA-122 and pro-neurotensin in the development, progression, and prognosis of NAFLD and NASH.

Abstract
Some studies suggest that thyroid hormones and disorders can influence breast (BC) and ovarian (OC) cancers risks. However, studies regarding their effect on these tumors progression are limited. Thyroid-stimulating hormone (TSH), T4, free T4 (FT4), T3, and free T3 (FT3) were detected in patients with BC, OC, benign breast and ovary diseases, and healthy controls using highly sensitive chemiluminescence assay. In contrast to OC, hypothyroidism prevalence was associated with BC late stage (11/24 vs. 2/46), high grade (11/23 vs. 4/47), lymph node invasion (11/42 vs. 0/28), positive distant metastasis (11/25 vs. 1/45), and large tumor size (14/25 vs. 1/45) compared to tumor early stages, low grades, negative lymph node, and distant metastasis and small size, respectively. Patients with late stage, high grade, large tumor size, positive lymph nodes, or positive distant metastasis were significantly (P < 0.05) associated with elevated levels of TSH and decreased levels of T4, FT4, T3, and FT3. There were both significant positive correlation of serum TSH and significant inverse correlation of T4, FT4, T3, and FT3 with these tumor worse outcomes. In conclusion, our results identify hypothyroidism as potentially important prognostic factor in BC not in OC that is associated with poor outcomes of BC patients.

Abstract
Background:
Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality.
There is a need for a marker associated with HCC progression. A disintegrin and metalloprotease
(ADAMs) family proteins have a lot of functions in cell adhesion, migration, proteolysis and
signaling.
Aims:
The aim of the study was to investigate the relation between ADAM 10 gene single nucleotide
polymorphisms (SNPs) and HCC progression.
Methods:
This study involved 201 cases divided: Group I (67 HCC patients), Group II (67 cirrhotic
patients), Group III (67 control). Each group was subjected to laboratory investigations: (CBC,
blood sugar, kidney and liver function, viral markers, alpha fetoprotein), imaging: (abdominal ultrasonography,
and triphasic C.T) and ADAM 10 gene polymorphism (rs 653765, rs 383902) detection
by real – time PCR.
Results:
There was a statistically significant difference in the frequency and genotyping of
ADAM10 SNPs in HCC patients in comparison to cirrhotic and control groups [the frequency of rs
653765 genotypes (p=0.015) and model (p=0.013)]; likewise, the frequency of rs 383902 genotypes
(p<0.001) and model (p=0.001)). Also, there was a statistically significant association between
different SNP rs 383902 genotype with CLIP stages (p=0.02) and with VISUM stages
(p=0.035).
Conclusion:
ADAM-10 is overexpressed in HCC patients and involved in HCC progress. These
findings highlight that ADAM inhibitor may be used as therapeutic goals in the treatment of HCC.

Abstract
AIM Nephrotoxicity is the major limiting factor for the clinical use of vancomycin (VCM) for treatment against multi-resistant Gram-positive bacteria. The present research aimed to investigate the ability of selenium nanoparticles (SeNPs) to protect against VCM-induced nephrotoxicity in rats. MAIN METHODS Experimental rats were divided into five groups; the first was the normal control, the second was treated with VCM (200 mg/kg twice/day, i.p.) for 7 days. The third, fourth, and fifth groups were treated orally with SeNPs (0.5, 1, and 2 mg/kg/day); respectively. SeNPs were administered for 12 days before VCM, 1 week simultaneously with VCM, and for another 1 week after its administration. KEY FINDINGS Levels of malondialdehyde (MDA), inducible nitric oxide synthase (iNOS), nitric oxide (NO), tumor necrosis factor-alpha (TNF-α), and kidney injury molecule-1 (KIM-1) were significantly increased in kidney tissue after VCM administration. Expression of adenosine 5'-monophosphate-activated protein kinase (AMPK), Bcl-2 associated X protein (Bax), caspase 3 and caspase 9 in kidney tissue was significantly increased, while the antioxidant enzymes, mitochondrial complexes, the ATP levels and B-cell lymphoma protein 2 (Bcl-2) were decreased in kidney in the VCM-treated rats compared to the normal control group. Treatment with SeNPs significantly decreased levels of MDA, iNOS, NO, TNF-α, and KIM-1 in the kidney tissue. Administration of SeNPs also downregulated the expression of the proapoptotic agents and enhanced the activities of the antioxidant enzymes and the mitochondrial enzyme complexes in the kidney. SIGNIFICANCE SeNPs alleviated VCM-induced nephrotoxicity through their anti-oxidant, anti-inflammatory, anti-apoptotic and mitochondrial protective effects.

Abstract
Background:MircoRNAs are endogenous, small non-coding RNA molecules that have been recognized as important modulators of gene expression. MicroRNA is considered one of the potential biomarkers of infection and inflammation. Our study aims to identify the potential role of miRNA-155, miRNA-146b, and Procalcitonin (PCT) in the early detection of spontaneous bacterial peritonitis in cirrhotic liver patients. miRNA-155 and 146b are molecular biomarkers , while procalcitonin is a serum marker in ascites patients complicated with Spontaneous Bacterial Peritonitis (SBP) .Methods:This study was conducted on 199 patients, 101 of them have ascites complicated with spontaneous bacterial peritonitis, and 98 patients without spontaneous bacterial peritonitis (control group). Ascitic fluid samples were collected from patients with SBP undergoing paracentesis at National Hepatology Institute in Egypt. MicroRNAs were determined in the serum using qPCR (quantitative polymerase chain reaction), while procalcitonin has been assessed in serum samples using ELISA (Enzyme-linked immune assay) technique.Results:Serum levels of miRNA-146b & miRNA-155 were significantly higher (p<0.001) in spontaneous bacterial peritonitis patients (79.2% and 97.0% respectively) than ascites patients (17.3% and 7.1%, respectively). Furthermore, the serum level of procalcitonin was significantly higher (p<0.001) in spontaneous bacterial peritonitis patients than that in ascites patients (68.3% and 27.6%, respectively).Conclusion:miRNA-155, miRNA-146b and procalcitonin can be used as early markers for the detection of SBP in hepatic patients with ascites.

Abstract
Metastasis in breast cancer is a leading cause of mortality among women in many countries. This study investigated the anti-cancer role of benzoimidazoquinazoline and benzimidazotriazin; two novel compounds that were designed, synthesized, structurally elucidated, and biologically evaluated as potent anti-angiogenic agents that act through inhibition of vascular endothelial growth factor receptor-2 (VEGFR2). Breast cancer was induced by inoculation of Ehrlich Ascites Carcinoma (EAC) cells. Seventy swiss albino mice were randomly divided into 7 groups, 10 animals each: (1) normal, (2) control EAC group, (3) cisplatin treated group, (4&5) benzoimidazoquinazoline treated (5 mg/kg and 10 mg/kg), (6&7) benzimidazotriazin treated (5 mg/kg and 10 mg/kg). The expression of miR-122 was assessed in the tumor tissue by quantitative PCR, and the VEGF level was determined in serum by ELISA. VEGFR2 and cluster of differentiation (CD)34 were assessed by immunohistochemistry. Serum ALT, AST, creatinine, and urea were measured. Treatment with benzoimidazoquinazoline and benzimidazotriazin decreased tumor weight and serum levels of VEGF, and down-regulated expression of VEGFR2 and CD34 in the tumor tissue. miR-122 was upregulated, particularly in the benzimidazotriazin (10 mg/kg) group. Relative to cisplatin, the novel compounds were less toxic to kidneys. Benzoimidazoquinazoline and benzimidazotriazin are promising anti-cancer agents that act through inhibition of angiogenesis and thus provide a new strategy for advancement of chemotherapy.

Abstract
This study aimed to investigate the impact of ginger extract (GE) loaded into chitosan nanoparticles (CNPs) in enhancing cytotoxicity and reducing cardiotoxicity of doxorubicin (DXN) in hepatocellular carcinoma (HCC) induced mice. DXN and GE were loaded into CNPs and cytotoxicity of loaded and unloaded drugs against HepG2 cells was evaluated. HCC was induced in male albino mice by injection of diethylnitrosamine (DINA). Mice were divided into eight groups (n = 15): (1) normal control, (2) DINA, (3) CNPs, (4) free DXN, (5) CNPs DXN, (6) free GE, (7) CNPs GE, and (8) CNPs DXN + CNPs GE. Both GE and DXN loaded into CNPs showed a greater decline in cell viability of HepG2 cells than the unloaded forms. GE CNPs displayed pronounced anticancer activity In Vivo through apoptosis, greater down-regulation of multidrug resistance 1, enhancement of anti-oxidant activity and depletion of vascular endothelial growth factor content in liver tissues. GE CNPs in combination with DXN CNPs showed nearly normal hepatic lobule architecture and the greatest increase in apoptotic cell count. Co-treatment group had decreased cardiac malondialdehyde, tumor necrosis factor-α and serum activity of creatine kinase and lactate dehydrogenase. Combination of GE CNPs and DXN CNPs might be a potentially effective therapeutic approach for HCC.

Abstract
This study aimed to investigate the potential role of co-treatment with doxorubicin (DOX) and verapamil (VRP) nanoparticles in experimentally induced hepatocellular carcinoma in mice and to investigate the possible mechanisms behind the potential favorable effect of the co-treatment. DOX and VRP were loaded into chitosan nanoparticles (CHNPs), and cytotoxicity of loaded and unloaded drugs against HepG2 cells was evaluated. Male albino mice were divided into eight groups (n = 15): (1) normal control, (2) diethylnitrosamine, (3) CHNPs, (4) free DOX, (5) CHNPs DOX, (6) free VRP, (7) CHNPs VRP, and (8) CHNPs DOX + CHNPs VRP. Either VRP or DOX loaded into CHNPs showed stronger growth inhibition of HepG2 cells than their free forms. DOX or VRP nanoparticles displayed pronounced anticancer activity in vivo through the decline of vascular endothelial growth factor and B cell lymphoma-2 contents in liver tissues, upregulation of antioxidant enzymes, and downregulation of multidrug resistance 1. Moreover, reduced cardiotoxicity was evident from decreased level of tumor necrosis factor-α and malondialdehyde in heart tissues coupled with decreased serum activity of creatine kinase-myocardial band and lactate dehydrogenase. Co-treatment with CHNPs DOX and CHNPs VRP showed superior results versus other treatments. Liver sections from the co-treatment group revealed the absence of necrosis, enhanced apoptosis, and nearly normal hepatic lobule architecture. Co-treatment with CHNPs DOX and CHNPs VRP revealed enhanced anticancer activity and decreased cardiotoxicity versus the corresponding free forms.

Abstract
Background Liver fibrosis is a major medical problem with high mortality and morbidity rates where the formation of regenerative nodules and cirrhosis leads to loss of liver function and may result in the development of hepatocellular carcinoma. bone marrow mesenchymal stem cells (BM-MSCs) have drawn attention as a novel approach for treatment of liver fibrosis. This study aimed to evaluate the therapeutic effect of BM-MSCs on the liver structure in carbon tetrachloride (CCl4) induced liver fibrosis in male rats relative to resveratrol and Silybum marianum as standard drugs derived from herbal plants. Methods Fifty adult male albino rats (Sprague Dawley strain; 180–220 g mean body weight) were purchased from the Laboratory Animal Unit in the Nile Center of Experimental Research, Mansoura, Egypt. Liver function were determined, isolation and preparation of BM- MSCs and detection of cell-surface markers by flow cytometry. Results Animals exposed to CCl4 developed liver injury characterized by significant increase of liver enzymes, malondialdehyde (MDA), tumor necrosis factor alpha (TNFα), and CYP450, inhibition of antioxidant enzymes, and decreased albumin. Treatment with stem cells enhanced liver state more effectively than resveratrol and S. marianum. It significantly decreased AST, ALT, ALP, MDA, TNF-α, and CYP450 and increased albumin, SOD, GSH, GST, and CAT. Histopathological study and atomic force microscope results confirmed the therapeutic effects of MSCs. Conclusions BM-MSCs could restore liver structure and function in CCL4 induced liver fibrosis rat model, ameliorating the toxicity of CCl4 and improving liver function tests.

Abstract
The genus
Natronolimnobius
, currently including four species, is a member of the order
Natrialbales
, class Halobacteria, and consists of obligately alkaliphilic and extremely halophilic members found exclusively in highly alkaline hypersaline soda lakes. The species were classified into this genus mostly based on phylogenetic analysis of the 16S rRNA gene. However, a more advanced phylogenomic reconstruction based on 122 conserved single-copy archaeal protein markers clearly indicates a polyphyletic origin of the species included into this genus, thus warranting its reclassification into three separate genera. We therefore propose to transfer Nlb. innermongolicus (type strain N-1311) to a new genus Natronolimnohabitans as Nlh. innermongolicus comb. nov. and to transfer Nlb. aegyptiacus (type strain JW/NM-HA 15) and Nlb. sulfurireducens (type strain AArc1) to a new genus Natrarchaeobaculum as Nbl. aegyptiacum comb. nov. and Nbl. sulfurireducens comb. nov. The phylogenomic differentiation of these four species is also supported by the ANI/AAI distances and unique phenotypes. The most important physiological differences includes a previously unreported ability for cellulose and xylan utilization in Nlb. baerhuensis, thermophily in Nbl. aegyptiacus and anaerobic sulfur respiration in Nbl. sulfurireducens. We further present an emended description of
Natronolimnobius baerhuensis

Abstract
BACKGROUND Long intergenic non-protein coding (lnc) RNA 00305 (LINC00305) is a pro-inflammatory atherosclerosis-associated lncRNA. We hypothesised that LINC00305 expression and its variant rs2850711 (A/T) are implicated in rheumatoid arthritis (RA) and linked with clinical and routine laboratory markers. METHODS 100 RA patients and 100 healthy controls were recruited. LINC00305 genotyping and expression were performed using allelic-discrimination PCR and quantitative real-time PCR. LINC00305 diagnostic power was evaluated using area under the receiver operating characteristic curve (AUC). Serum nuclear factor- κB (NF-κB) and matrix metalloproteinase-3 (MMP-3) levels were determined by ELISA, standard laboratory markers by routine methods. RESULTS LINC00305 expression was significantly increased in RA patients and positively correlated with DAS28, C-reactive protein, erythrocyte sedimentation rate, rheumatoid factor and anti-cyclic citrullinated peptide antibody. In multivariate analysis, NF-κB, MMP-3 and LINC00305 were significant predictors of RA (P< 0.0001). Individuals carrying AT and TT genotypes of rs2850711 polymorphism had significantly more likely to have RA than AA genotype carriers (P< 0.05). LINC00305 expression, DAS28 score and serum levels of NF-κB and MMP-3 were significantly increased in the patients carrying LINC00305 AT and TT genotypes as compared with AA genotype patients (P< 0.01). CONCLUSION Increased expression level of LINC00305 and its rs2850711 genetic variant may play a role in the diagnosis and management of RA, and its severity and activity.

Abstract
Essential hypertension is a chronic medical condition affecting thousands of people worldwide. Hypertension results from interplay of genetic and environmental factors. MicroRNAs regulate gene expression and can be biomarkers for disease. MicroRNA let-7e and microRNA 296-5p have been linked to different cardiovascular diseases. This study aimed to determine association of serum miRNA let-7e and miRNA 296-5p with essential hypertension in Egyptian patients. MicroRNA let-7e and miRNA-296-5p expression was determined in sera of 25 hypertensive patients and 25 normotensive controls by quantitative real-time polymerase chain reaction. Hypertensive patients showed significantly higher expression of miRNA let-7e (3.23-fold increase, p = 0.036) in comparison with normotensive controls. In hypertensive patients, miRNA let-7e expression was positively correlated with increased systolic and diastolic blood pressure. Furthermore, miRNA 296-5p expression was negatively correlated with serum total cholesterol and low-density lipoprotein. Results from this study indicate that miRNA let-7e can potentially be a biomarker for essential hypertension.

Abstract
Obesity is a proven risk factor for neurodegenerative disease like Alzheimer's disease (AD). Accumulating evidences suggested that nutritional interventions provide potential for prevention and treatment of AD. The present study aimed to investigate the effect of dietary treatment of obese rats with natural Raspberry ketone (RK) and their relationship with neurodegeneration. Obesity was first induced in 40 male Wistar rats (140-160 g) by feeding high fat diet (HFD) for 16 weeks. Obese rats were then assigned into 4 groups (n = 10 each). (O-AD) is obese induced AD group maintained on HFD for another 6 weeks. OCR is obese group received calorie restricted diet for 6 weeks. OCRRK is obese group received calorie restricted diet and RK (44 mg/kg body weight, daily, orally) for 6 weeks and OCRD is obese group received calorie restricted diet and orlistate (10 mg/kg body weight, daily orally) for 6 weeks. Another 10 normal rats received normal diet were used as normal control group (NC). Body weight, visceral white adipose tissue weight (WAT), lipid profile, oxidative stress markers, adiponectin, cholinergic activity and amyloid extracellular plaques were examined. In addition to histological changes in brain tissues were evaluated.Raspberry ketone (RK) via its antioxidant properties attenuated oxidative damage and dyslipidemia in O-AD group. It inhibited acetylcholinesterase enzyme (AchE) and hence increased acetylcholine level (Ach) in brain tissues of O-AD rats. It is also impeded the upregulation of beta-secretase-1 (BACE-1) and the accumulation of amyloid beta (Aβ) plaques which crucially involved in AD. The combination of CR diet with RK was more effective than CR diet with orlistate (antiobese drug) in abrogating the neurodegenerative changes induced by obesity. Results from this study suggested that concomitant supplementation of RK with calorie restricted regimen effectively modulate the neurodegenerative changes induced by obesity and delay the progression of AD.

Abstract
OBJECTIVE This study aimed to assess the relation of locus 1p13 rs646776 (T/C) polymorphism with preeclampsia in Egyptian women. METHODS The study included 100 healthy pregnant female subjects and 100 preeclampsia patients. The genotypes of the polymorphisms were assessed. Endothelin-1 level was determined in plasma. RESULTS The major T allele of the 1p13.3 genomic region rs646776 polymorphism had a higher frequency in preeclampsia patients. Carriers of C allele had significantly lower endothelin-1 levels, lower systolic and diastolic blood pressure, decreased proteinuria, and increased HDL-C in the patients. CONCLUSION The rare C allele of rs646776 polymorphism in chromosomal locus 1p13.3 is associated with decreased risk of preeclampsia.

Abstract
BACKGROUND Intestinal fatty acid-binding protein 2 (FABP2) is expressed in enterocytes and binds saturated and unsaturated long-chain fatty acids. The FABP2 Ala54Thr polymorphism has been reported to effect lipid metabolism. The aim of the present study was to assess the relationship between this polymorphism and peripheral atherosclerosis combined with type 2 diabetes mellitus (T2DM) in an Egyptian population. METHODS The study was performed on 100 T2DM patients with peripheral atherosclerosis and 100 control subjects. The Ala54Thr polymorphism was analyzed by polymerase chain reaction-restriction fragment length polymorphism, whereas serum FABP2 levels were determined using ELISA. Fasting blood glucose, fasting serum insulin concentrations, HbA1c, lipid profile, body mass index (BMI) and systolic and diastolic blood pressure (SBP and DBP, respectively) were determined. RESULTS There was a higher frequency of the Thr54 allele among the patient group (P = 0.002). In Ala54/Thr54 heterozygotes and carriers of the rare Thr54/Thr54 genotype, there were significant increases in BMI and FABP2. Those with the Thr54/Thr54 genotype had significantly decreased high-density lipoprotein cholesterol (HDL-C) concentrations; in addition, those with the Thr54/Thr54 genotype had significantly higher SBP and DBP than subjects with the Ala54/Ala54 and Ala54/Thr54 genotypes. There was a positive correlation between FABP2 levels and BMI, SBP and DBP, and a negative correlation with HDL-C. CONCLUSIONS The Thr54 allele of the FABP2 Ala54Thr polymorphism was associated with an increased incidence of peripheral atherosclerosis combined with T2DM in the population studied.

Abstract
AIM The metabolic syndrome is a complex of interrelated risk factors for cardiovascular disease and diabetes. The adipokines, chemerin and vaspin, are known to have metabolic regulatory roles. This study aimed to assess the relation of chemerin rs17173608 and vaspin rs2236242 polymorphisms with metabolic syndrome and its related phenotypes in Egyptian women. SUBJECTS AND METHODS The study included 100 healthy female subjects and 100 metabolic syndrome patients. The component traits of metabolic syndrome were determined and the genotypes of the polymorphisms were assessed using the tetra amplification refractory mutation system polymerase chain reaction procedure. RESULTS The minor G allele of the chemerin rs17173608 polymorphism had a significantly higher frequency in metabolic syndrome patients (p = 0.0001). The component traits of metabolic syndrome were significantly increased in the carriers of the GG and TG genotypes. In contrast, the rare A allele of vaspin rs2236242 polymorphism was significantly higher in the control subjects (p = 0.005). The carriers of the TA and AA genotypes showed significant relation with lower values of the phenotypes of metabolic syndrome. CONCLUSION Metabolic syndrome in Egyptian females is associated with the minor allele of chemerin rs17173608 polymorphism, whereas the minor allele of vaspin rs2236242 polymorphism plays a protective role against metabolic syndrome.

Abstract
OBJECTIVE To determine whether computer-predicted short RNA structural analogues could inhibit hepatitis C virus (HCV) genotype 2a, 3a and 4a replication in cultured cells. METHODS Short RNA sequences, X12, X12a and X12b, designed to be identical in secondary structure to the X region in the 3'-untranslated region (3'-UTR) of the HCV 1b genome, as well as shorter stem-loop components of X region, were inserted into a plasmid and transfected into separate Huh7.5 human hepatoma cells stably transfected with subgenomic replicons for genotypes 2a, 3a and 4a. All replicons included a firefly luciferase reporter gene. After 48 h of plasmid transfection, the inhibition of HCV replication was determined by HCV RNA isolation and quantification by real-time polymerase chain reaction and luciferase assays. RESULTS All the secondary structural analogues to genotype 1b X region cross-inhibited genotype 2a, 3a and 4a replicons. The maximum inhibition by genotype 1b X region structural analogues was obtained against genotype 2a cells in which X12, X12a and X12b inhibited replication by 30%, 63% and 72%, respectively (P < 0.05 for all), compared to an unrelated hepatitis B viral analogue. CONCLUSIONS Despite substantial sequence dissimilarity, HCV RNA genotype 1b X region analogues cross-inhibited the replication of HCV genotypes 2a, 3a and 4a. Particular conformations and not the sequence of the stem-loops of the X region are involved in HCV replication.

Abstract
Alteration in microRNA-146a (miRNA-146a) expression is an important event in the pathogenesis of many human diseases. MiRNA-146a rs2910164 is a functional polymorphism that showed association with several diseases. Metabolic syndrome is an aggregation of multiple risk factors including impaired glucose tolerance, increased highdensity lipoprotein, abdominal obesity, and high blood pressure. The aim of this study was to assess the relation of miRNA-146a rs2910164 with metabolic syndrome and its component traits in Egyptian women from the Suez Canal area. The study included 100 healthy female subjects and 100 metabolic syndrome patients. The component traits of metabolic syndrome were determined and the genotypes of the polymorphisms were assessed using the polymerase chain reaction-restriction fragment length polymorphism technique using the restriction enzyme Hpy188I. The rare C allele had a significantly higher frequency in metabolic syndrome patients (P = 0.013). The heterozygote GC and the rare CC genotypes showed a significant increase in body mass index, waist circumference, triglycerides, total cholesterol, low-density lipoprotein, systolic and diastolic blood pressure. The GC genotype was associated with higher fasting blood glucose, fasting serum insulin and insulin resistance. The carriers of CC genotype had significantly lower HDL compared with the GG genotype carriers. In conclusion, The C allele of miRNA-146a rs2910164 showed positive association with increased susceptibility to metabolic syndrome and its phenotypes in the study population.

Abstract
Extracellular gluco-amylo-pullulanase from Amphibacillus sp. NM-Ra2 was purified to homogeneity by ethanol precipitation, anion exchange chromatography and gel filtration chromatography. Molecular mass of the enzyme was 50kDa (SDS-PAGE). The enzyme showed maximal activity at 1.9 M NaCl, pH50°C 8.0 and 54°C and was active from 0 to 4.3 M NaCl and 37 to 65°C. The enzyme was inhibited by EDTA and was stable and active in the presence of PMSF, DTT, H2O2, Triton-X-100, Tween 20 and Tween 80. Ca2+ is inessential for activity. The amylase was stimulated with K+ and inhibited with Cu2+ and Mg2+. Hg2+, Zn2+ and Fe2+ had no effect on activity. Amylase was stable and active in the presence of ethanol, methanol and benzene (25%, v/v). The enzyme hydrolyzed linear and branched polysaccharides including pullulan, glycogen and amylopectin, and hydrolyzed raw wheat starch and raw corn starch (14.6% and 13.5% over 2 h). Amylase activity was inhibited by soluble starch concentrations greater than 0.3%. The major products of soluble starch hydrolysis were maltose and maltotriose. The amylase, being halophilic and alkali-thermostable, in addition to being resistant to surfactants, oxidizing agents and organic solvents, can find applications in the starch processing, pharmaceutical, food and paper/pulp industries.

Abstract
OBJECTIVE Metabolic syndrome is a risk factor for coronary heart diseases as well as diabetes, fatty liver and several cancers. The prevalence of metabolic syndrome in women appears to be increasing, particularly in women of childbearing age. In the present study, we assessed the association of estrogen receptor-alpha gene polymorphisms (XbaI and PvuII) with metabolic syndrome and its related phenotypes. MATERIALS/METHODS One hundred and fifty Egyptian female patients with metabolic syndrome (mean age 35.52±6.86) were compared with one hundred and fifty age matched healthy Egyptian women (controls). The component traits of metabolic syndrome were determined, and the XbaI and PvuII genotypes were assessed with the PCR-RFLP method. RESULTS Our data indicated a significant difference in the allele frequencies of XbaI, but not PvuII, between the metabolic syndrome and control groups (P=0.0003 and P=0.164). Carriers of the minor alleles of XbaI and PvuII gene polymorphisms, in either the homozygous or heterozygous form, were associated with high diastolic blood pressure, high total cholesterol and LDL-c levels, increased HOMA-IR values and decreased QUICKI values compared to carriers of the major allele. However, only the minor G allele of XbaI was associated with measures of adiposity, specifically, BMI and waist circumference. CONCLUSIONS The XbaI polymorphism of the estrogen receptor alpha gene is associated with metabolic syndrome. On the other hand, PvuII gene polymorphism is not associated with the occurrence of the disease in this sample of Egyptian women.
