After 3 days, the cells were split 110 and reseeded in the presence of inhibitors. On day 6, cell culture growth/viability was monitored by MTS sellckchem assay. Relative growth, compared to vehicle-treated controls, was used to calculate the fraction affected and the combination index for each experimental combination, using the CalcuSyn software. Western blotting The cells were harvested, washed with ice-cold PBS and resuspended in lysis buffer as described [19]. Total cell extracts were loaded on SDS-PAGE, transferred to a nitrocellulose membrane and probed with the indicated primary antibodies overnight at 4��C. Proteins were revealed by chemiluminescence after incubation with HRP-conjugated secondary antibodies (GE Healthcare, diluted 12500). Soft-agar colony assay Ten thousand cells were embedded in RPMI containing the indicated compounds and 0.

3% low-melting agarose type VII (Sigma-Aldrich) and seeded on top of a 0.5% agarose/RPMI support layer in 6-well plates. Fresh inhibitors were added every 7 days to the top agar layer. The colonies were counted after 20 days. Quantitative real-time PCR Cells were treated with vehicle or inhibitors for 24 or 72 hours and harvested. Total RNA was extracted with TRIzol reagent (Invitrogen) and retrotranscribed with random hexamers using a standard procedure. For the 96-well array gene set, forward and reverse primer mix (5 pmol each) was spotted in the corresponding well for each target gene and the plates were kept frozen at ?80��C until needed.

The reaction mix (2 ��l cDNA, 10 ��l Brilliant III Ultra-Fast SYBR? Green QPCR Master Mix and 7 ��l water, per well) was added to the pre-made plates and quantitative PCR was run on a Stratagene MX3000P detection system, under the following conditions: 95��C, 3 min (1 cycle); 95��C, 10 sec, 60��C, 20 sec (40 cycles). The confirmation run was performed in triplicate using the standard real time PCR protocol recommended by the manufacturer. The GAPDH housekeeping gene was always used as an internal reference. Primers for GAPDH were TGCACCACCAACTGCTTAGC (forward) and GGCATGGACTGTGGTCATGAG (reverse). The primers for all other genes are listed in the Table S2. Results PKF115-584 (figure 1A) and pyrvinium pamoate (figure 1B) have been shown to interfere with the ��-catenin-associated transcriptional complex through different mechanisms.

In order to verify the activity of the two drugs in CRC cells, we characterized their effects in the Ls174T cell line, carrying ��-catenin and KRAS activating Dacomitinib mutations [30], [33]. This cell line was initially chosen as a model because it was previously used to characterize the effects of siRNA-mediated gene silencing [19]. As reported in figure 1D�CE, both drugs inhibited cell growth in a dose-dependent manner. Similar growth inhibition was obtained in DLD-1 cells, which express a truncated APC allele (figure S1A�CB).

1b). These neutrophils frequently assembled into aggregate structures around hepatocytes with macrovesicular steatosis, resembling selleck chem Imatinib the crown-like macrophage structures found in adipose tissue of obese animals [21]. Thus, hepatic lipid accumulation triggered by a high-fat diet is associated with liver neutrophil infiltration, leading to increased hepatic MPO protein levels. Figure 1 Strong high-fat diet-induced induction of MPO in the liver. Reduced MPO Activity in LDLR?/?/MPO?/?tp Mice The accumulation of MPO in the liver upon high-fat feeding suggested that MPO might contribute to the pathogenesis of NASH. To further examine the role of MPO in NASH, we took advantage of the fact that MPO is exclusively expressed in the hematopoietic system [22], and performed bone marrow transplantation experiments that resulted in the generation of combined MPO-deficient, LDL-R-deficient mice (LDLR?/?/MPO?/?tp) mice.

LDLR?/?/MPO+/+tp controls and LDLR?/?/MPO?/?tp mice had a similar body weight, and diet-induced weight gain was comparable (LDLR?/?/MPO+/+tp from 19.9��0.4 to 21.8��0.3 g, LDLR?/?/MPO?/?tp: from 20.0��0.2 to 21.9��0.7 g). After high-fat feeding, MPO plasma levels in the LDLR?/?/MPO+/+tp mice were 324 ng/ml whereas plasma from LDLR?/?/MPO?/?tp animals contained only 22 ng/ml of MPO (p<0.01; Fig. 2a). Similar to plasma MPO, liver MPO was very significantly reduced in the LDLR?/?/MPO?/?tp group after high-fat feeding as shown by quantification of MPO-positive cell numbers, with levels well under those observed in chow-fed LDLR?/?/MPO+/+ mice(p<0.001; Fig. 2b).

Figure 2 Reduced hepatic MPO and MPO-derived nitrated proteins in LDLR?/?/MPO?/?tp mice after 8 weeks of high-fat feeding. To investigate if the marked reduction of hepatic MPO in LDLR?/?/MPO?/?tp mice translated into diminished generation of MPO-mediated cytotoxic products, we studied hepatic levels of nitrotyrosine, a protein modification generated at sites of inflammation as a result of the activity of several enzymes among which MPO, which accumulates in NAFLD [5], [8], [23]. As expected, mice in the LDLR?/?/MPO?/?tp group displayed significantly reduced levels of nitrotyrosine in the liver, consistent with reduced MPO activity (Fig. 2c; p<0.05). Characterization of NASH Severity Histological examination of the livers after H/E-staining revealed diffuse microvesicular and macrovesicular steatosis in both groups (Fig.

3). Semi-quantitative evaluation of the extent of steatosis showed no statistically significant differences between LDLR?/?/MPO+/+tp and LDLR?/?/MPO?/?tp mice (2.4��0.3 Brefeldin_A vs. 2.1��0.2, p=0.43). Inflammatory cell foci were observed in both groups, but less frequently found in the LDLR?/?/MPO?/?tp group, although the difference was not statistically significant (0.75��0.31 vs. 0.50��0.27, p=0.12). Hepatocyte ballooning, a feature of progressive human NASH, was not observed in either group.

3A). Accordingly, USP18 protein was detectable from 16 hours on at all time points by Western blot and IHC analyses (Figure (Figure3,3, B and C). Presumably for technical reasons, we could not detect SOCS1 or SOCS3 proteins at any time point, despite testing several different antibodies. Romidepsin FDA Figure 3 The negative regulator USP18 is continuously upregulated during the entire week after pegIFN-��2b injection. We conclude that pegIFN-��2b induces transient activation of the Jak/STAT signaling pathway in hepatocytes because of the rapid induction of SOCS1, SOCS3, and USP18 and that the signaling pathway remains refractory to ongoing stimulation by circulating pegIFN-��2b because of the persistent induction of USP18. pegIFN-��2b�Cinduced genes fall into four robust classes with distinct temporal expression patterns.

We assessed pegIFN-��2b�Cregulated gene expression with transcriptome analysis using Affymetrix U133 Plus 2.0 arrays. Pairwise comparison of pretreatment and on-treatment biopsies revealed a greater than 2-fold induction in two-thirds of samples of hundreds of genes, with a peak at 16 hours (Figure (Figure4A4A and Supplemental Table 1; supplemental material available online with this article; doi: 10.1172/JCI70408DS1). Likewise, up to 200 genes were downregulated (Supplemental Table 2). To gain insight into the temporal expression patterns of ISGs induced by pegIFN-��2b in the human liver, we analyzed the transcriptome data using a Bayesian clustering algorithm.

The algorithm produced four robust clusters of upregulated genes, which were termed early (144 genes), intermediate (31 genes), late (299 genes), and very late ISGs (20 genes) (Figure (Figure4B4B and Supplemental Table 1). For over 95% of all upregulated genes, the peak mRNA levels occurred 4 or 16 hours after injection, followed by a steady decline over the remaining 128 hours of treatment (Figure (Figure4B).4B). Because of the limited amount of tissue obtained by percutaneous liver biopsies, we could not comprehensively analyze ISG protein expression. We therefore measured the protein expression of three exemplary ISGs. USP18 protein expression peaked at the 16-hour time point and then gradually declined, but remained induced up to the 144-hour time point. We found that USP18 mRNA expression peaked already at 4 hours, but was also persistently induced up to the 144-hour time point (Figure (Figure3).

3). STAT1 mRNA was induced up to the 96-hour time point, whereas STAT1 protein expression was still increased at 144 hours (Supplemental Figure 1). We found a very good correlation between IP10 mRNA expression in the liver and IP-10 Batimastat protein concentration in the serum (Supplemental Figure 1). Taken together, we found a reasonably good correlation between mRNA and protein expression of ISGs in this limited set of exemplary ISGs. Figure 4 pegIFN-��2b�Cinduced genes fall into four robust classes with distinct temporal expression patterns.

CD133, CD166, CD44, CD24, CD90, EpCAM, and ABCG5 were evaluated for both membrane and cytoplasmic staining; ALDH1 was exclusively evaluated in the cytoplasm of tumor buds. The number of CD166, CD44s, http://www.selleckchem.com/products/PF-2341066.html EpCAM, ALDH1, CD133, CD24, CD90, and ABCG5 positive tumor buds was then evaluated in the area of densest tumor budding as determined by CK22 staining. Statistical analysis Univariate survival analysis was carried out using the Kaplan-Meier method and log rank test. Two multivariable Cox regression analyses were performed. First, to test the independent prognostic value of tumor budding, the effects of pT stage, pN stage, tumor grade, and vascular invasion were adjusted for.

Subsequently, because of the small number of positive cases, only 2 variables could be entered into the multivariable Cox regression analysis along with positive expression of the protein in tumor buds, hence pT classification and pN classification were selected. The assumption of proportional hazards was verified prior to this analysis. Hazard ratios (HR) and 95% CI were obtained to determine the prognostic effect of positive cases adjusting for pT and pN. Kendall��s correlation coefficient (r) was obtained for correlation analysis of markers. P < 0.05 was considered statistically significant. RESULTS Prognostic value of tumor budding In order to confirm the prognostic value of tumor budding in our series, cases were divided into 3 groups based on the distribution of number of tumor buds: those with < 40 buds, between 41-60 buds, and finally those with > 60 buds per 20 �� field.

The greater the number of tumor buds the more unfavorable was the prognosis both in univariate (P < 0.001) and multivariable analysis with pT, pN, tumor grade, and vascular invasion (HR: 1.6, 95% CI: 1.2-2.1). Expression of putative stem cell markers within tumor buds CK22 staining was used to identify regions of densest tumor budding with epithelial cells exclusively immunoreactive for the protein. Staining for ABCG5, ALDH1, CD133, CD166, CD24, and CD44s could be observed in both tumor cells and inflammatory or stromal cells. EpCAM staining was predominantly limited to expression in tumor cells whereas CD90 was almost always expressed by stromal cells and only in 3 cases in the tumor itself. Marker expression was then evaluated in the area of densest budding. Representative immunostains for all markers are shown in Figure Figure2.

2. Only one case (1.03%) was positive for CD90, while 5 (5.1%) and 6 (6.1%) cases were positive for CD44s and CD133, respectively. On the other hand, a considerably larger number of positive cases was found to express ALDH1 (16/97, 16.5%), CD24 (16/99, 16.2%) and CD166 (34/100, 34%). Finally, ABCG5 and EpCAM staining Batimastat were frequent events with 39/97 (40.2%) and 69/100 (69%) positive cases, respectively (Figure (Figure33).

2A). Then we investigated whether STAT3 phosphorylation could be inhibited by sgp130Fc treatment using immunofluorescence staining. While the expression Alvespimycin of STAT3PY705 was highly up-regulated in the colon tissues of the 3% DSS-treated group, it was notably repressed in the group of mice treated with 3% DSS and a subsequent injection of sgp130Fc (Fig. 2B). Remarkably, a significant reduction in the expression of S100A9 mRNA (Fig. 2C) and protein (Fig. 2D) was observed in CECs from the 3% DSS + sgp130Fc group compared to mice receiving DSS alone, and was associated with STAT3PY705 expression (Fig. 2B). Figure 2 Effect of soluble gp130-Fc (sgp130Fc) injection on the expression of S100A9 in colonic epithelial cells (CECs) from mice with dextran sulfate sodium (DSS)-induced colitis.

Next, to provide direct evidence that the increased S100A9 expression by IL-6 was mediated through STAT3 activation, we introduced a delivery system of si-STAT3 using CH-NPs [44]. si-negative/CH-NPs or si-STAT3/CH-NPs were injected intravenously twice on days 2 and 3 into the 3% DSS-treated group. Then we also investigated whether STAT3 knockdown could affect disease development using si-STAT injection. Disease activities were significantly decreased on day 6 of DSS exposure in the STAT3 suppression group compared to the negative si-RNA-treated mice (Fig. 3A). The expression levels of S100A9 mRNA (Fig. 3B) were notably suppressed in the group of mice treated with si-STAT3/CH-NPs, resulting that STAT3 regulated the expression level of S100A9 in the CECs in DSS-induced colitis (Fig. 3C).

Figure 3 Effect of small interfering STAT3 chitosan nanoparticle (si-STAT3/CH-NP) injection on the expression of S100A9 in colonic epithelial cells (CECs). IL-6/STAT3 Signaling Cascades Induce S100A9 Expression in Caco-2 Cells In Vitro To further confirm whether IL-6 directly triggers S100A9 expression through STAT3 activation, in vitro experiments were performed using a human IEC line (Caco-2). Sustained STAT3 activation was observed until 60 min (Fig. 4A) and S100A9 expression was significantly increased at mRNA levels after IL-6 stimulation for 3 or 6 h (Fig. 4B). S100A9 was released in the cell culture supernatant up to 24 h after stimulation of these cells with IL-6 (Fig. 4B). Thus, IL-6 can be postulated to mediate phosphorylated STAT3 and up-regulate S100A9 expression in Caco-2 cells.

Figure 4 The role of the interleukin-6 (IL-6)/STAT3 axis in the expression of S100A9 in the Caco-2 cell line. IL-6-mediated S100A9 expression was further investigated to determine whether it is dependent on STAT3 activation using various agents that inhibit STAT3 signaling cascades. S3I and the STAT3 inhibitor, which inhibit phosphorylation by targeting a tyrosine residue or by dimerizing STAT3, respectively were incubated for 3 Entinostat h prior to IL-6 stimulation. After 6 h, the expression of S100A9 at both mRNA and protein levels was measured.

4B, repeating the experiment using selleck chem Dasatinib the ADAM17/TACE-specific Innozyme TACE activity assay confirmed that the increase was due, at least in part, to KK-dependent activation of ADAM17. The KK effect was detectable within 5 min of exposure and persisted for at least 15 min. FIGURE 4. Plasma kallikrein causes PAR-dependent ADAM17 activation in vascular smooth muscle cells. A, serum-deprived R-VSMCs in 96-well plates were treated with varying concentrations of plasma KK for 4 h in the presence of the ADAM10/17-specific fluorogenic peptide … Because ADAM17 is regulated by multiple stimuli, including many G protein-coupled receptors (26, 27), we next tested whether there was a link between KK-dependent PAR activation and its activation of ADAM17 in R-VSMC.

For these experiments, R-VSMCs were preincubated in the presence of PAR1 or PAR2 antagonist peptides prior to exposing the cells to KK. As these peptides are related to the internal PAR1/2 ligand sequence, we first had to exclude the possibility that they would also behave as pseudosubstrate inhibitors of plasma KK. As shown in Fig. 4C, neither peptide had any effect upon KK activity when assayed in a cell-free system. Similarly, neither peptide interfered with the ability of recombinant ADAM17/TACE to cleave its fluorogenic substrate, KPLGL-Dpa-AR-NH2, in a cell-free assay (data not shown). However, as shown in Fig. 4D, the PAR1 and PAR2 antagonist peptides blocked KK-induced ADAM activation in R-VSMCs, suggesting that KK cleavage of PARs occurs upstream of ADAM activation.

The two inhibitors in combination were somewhat more effective that either alone; however, the difference was not statistically significant. Plasma Kallikrein Stimulates ADAM-dependent Amphiregulin Release and EGF Receptor Transactivation in Primary Aortic Vascular Smooth Muscle ADAMs are known to play a key role in the regulated shedding of at least six of the known EGF family ligands, transforming growth factor-��, EGF, HB-EGF, betacellulin, epiregulin, and AR (46). Of these, HB-EGF and AR have been implicated in the control of VSMC proliferation and development of vascular disease (28,�C30, 47,�C49). To determine whether the KK-induced increase in ADAM activity increased VSMC shedding of EGF family growth factors, we looked for the presence of AR and HB-EGF in the culture medium after KK exposure.

Because species-specific antibodies Drug_discovery recognizing rat AR and HB-EGF are not available, we employed primary H-VSMC for these experiments. As shown in Fig. 5A, KK exposure increased in AR shedding compared with vehicle-treated control cells. As shown in Fig. 5B, KK-stimulated AR release was ADAM-dependent, because it was sensitive to the broad spectrum MMP inhibitor GM6001. Although we were unable to detect HB-EGF shedding in response to plasma KK (data not shown), we did observe increased shedding of another ADAM17/TACE substrate, TNF-��, consistent with the results of our direct assay of ADAM17/TACE activity.

The 2 other cases were dense tumors and had volumes of 0.22cm3 and 0.41cm3. This selleck chemicals Volasertib fact was also described by Langer et al. who investigated the outcome of diffusion weighted MRI (DWI) and T2w-MRI in dependence of histological tumor composition [23]. Similar to RTE, DWI assesses tissue information due to cell density: the denser the cancer, the higher the diffusion restriction. All of their ��invisible�� tumors also had predominant Gleason pattern 3 and showed sparse architecture on histology, so that they did not significantly differ from healthy prostate tissue. The authors concluded that this may limit T2w-MRI and DWI in the detection and the assessment of tumor volume of some cancers.Figure 6Outlined sparse cancer lesion PZ base right on whole-mount step section (a), no suspicious changes on macroscopic specimen (b), elastogram (c), and grey-scale ultrasound (d).

Some cancer lesions may be negative on RTE, but positive on CE-TRUS [20]. Maybe this multiparametric way��adding tissue informations about contrast media dynamics to grey-scale ultrasound and RTE��could have detected some of our false negative findings. Brock et al. have shown the usefulness of this approach, whereas Nyg?rd et al. demonstrated the benefit of adding new biomarkers, like PCA-3, to RTE findings for the detection of significant disease [24, 25].Our study has several limitations. (1) We do not have data about intra- and interobserver variability. (2) We have used only one US system for RTE. The reproducibility of our results with other US systems needs to be evaluated in further studies.

(3) We focused this study on correlating tumor sizes; we did not correlate right negative results between RTE and histopathologic specimens. (4) We investigated the PZ only due to the above mentioned reasons. (5) We knew that every patient had PCa, which is a bias. (6) The planes of whole-mount step sections had an orientation of 90�� to the urethra, while an endfire transducer provides images in different angles. Therefore it could be difficult to be sure, whether the identical geographic areas were compared. An investigation with 3D/4D ultrasound would be desirable. 5. ConclusionRTE is capable of detecting significant PCa with high sensitivity, but can have problems when visualizing tumors with sparse architecture. Therefore, adding information about contrast media dynamics in a multiparametric way may decrease the number of false negative cases. In the detection of smaller cancer lesions, RTE is of limited value.Conflict of InterestsThe authors declare that they have no conflict Brefeldin_A of interests.Authors’ ContributionD.

Phenolics can be subdivided into phenolic acids, flavonoids, quinones, tannins, coumarins, and simple phenols [3]. These antimicrobial compounds from plants also have potential to inhibit bacteria through different mechanisms other than those presently used by antibiotics and this may have full article clinical value in treatment of resistant microbial strains [4].In this connection Listeria species is one such bacteria with increasing reports of its resistance to conventional antibiotics [5�C8]. Listeria species are Gram-positive bacteria that are widespread in nature and they have been recovered from raw vegetables, raw milk, fish, poultry, and meats, such that infection most likely begins following ingestion of the organism in contaminated food, and clinical manifestations of the invasive listeriosis are usually severe and may include abortion, sepsis, and meningoencephalitis [9].

Listeria crosses the mucosal barrier of the intestine and, once in the bloodstream, may disseminate hematogenously to any site although the liver is thought to be the first target organ, where active multiplication occurs until cell-mediated immune response gains control of the infection [9, 10]. In healthy individuals the continual exposure to listerial antigens may result in maintenance of antilisteria memory T cells; however in immune-compromised individuals this exposure may result in prolonged bacteremia and progress to overt listeriosis such that approximately 70% of nonperinatal Listerial infections occur in individuals with malignancies, AIDS, organ transplants, or in those receiving corticosteroid therapy [9].

The case-fatality rates of Listeria infection vary from country to country, but invariably the highest mortality is among newborns (25%�C50%) due to infection acquired from their mothers, whilst mortality among those over 60 years of age is also high ranging between 10%�C20% [11].Given the high mortality rates of Listeria infection against a background of antibiotic resistant strains it becomes imperative to explore for alternative forms of treatment, and having acknowledged Carfilzomib the medical importance of plant remedies and their potential in curbing antibiotic resistance this study therefore focuses on the antilisterial activities of the crude methanol extract of Garcinia kola seeds. Garcinia kola is a traditional medicinal plant which has been used since time immemorial for its medicinal purposes mainly in its indigenous origins of central and West Africa [12].

During years 2004 and 2006 the maps show that populations placed on the Northwest, at higher altitudes, contribute the most to the higher poaceae pollen concentration in the air (Figures (Figures66 and and8).8). On the contrary, during year 2005, populations placed on the south, at lower altitudes, contribute our website the most to the hightest poaceae pollen concentration in the air, recorded during the week from April 29th to May 05th (Figure 7). Nonetheless, populations placed in the north area seem to contribute to high concentrations registered during subsequent weeks, as well.Figure 6Phenological maps. Year 2004.Figure 7Phenological maps. Year 2005.Figure 8Phenological maps. Year 2006.4. DiscussionMost phenomena show, as an inherent feature, a high degree of spatial continuity Moral [21].

In ecological research, there are many instances where it is necessary to interpolate among spatially stratified samples which is the reason because in last years GISs and geostatistics are being applied to environmental studies such as entomology [9] plant distribution [13, 24], and general ecology [25] with excellent results.Traditionally plant flowering phenological studies have been focused on changes through time. Patterns across space remain largely unexplored. Only few works have developed models in terms of both space and time [26�C28]. In the present paper the working hypothesis that starting from several sampling points randomly distributed through the city and the Sierra Norte of C��rdoba we would be able to obtain valuable phenological information of V. geniculata was confirmed.

By using georeferenced data, phenological maps of a given area can be constructed. Kriged estimates were subsequently used to map phenological variations to visualize changes through the space. The present work indicates that V.geniculata phenology is highly associated to altitude and topographic situation.In recent years, there has been a surge of interest in phenology as an indicator AV-951 of global climate change effects, particularly during spring months [29, 30]. In this context, located plant phenology data and phenological maps provide real data as how the climate affects the phenology of plants and their possible adaptations to new climate scenarios [5, 31]. Systematic future measurement of floral phenology in located points could provide extended maps that would offer valuable information about the biological impacts of climate change on different species.In relation to the use of validated phenological maps constructed by interpolation we can conclude that the obtained maps are a valuable tool to interpret grass airborne pollen concentrations registered in Cordoba.

Results and selleck catalog DiscussionChemical composition of spices is given in Table 1. The results indicated that mustard, black cumin, and cress seeds had higher fat content of (38.45%), (31.95%), and (23.19%), respectively, as compared to clove (16.63%), black pepper (5.34%), and fenugreek (4.51%) seeds. It could be noticed that cress, mustard, black cumin, and black pepper had higher protein content that ranged from 20.61% to 25.45%, as compared to fenugreek (12.91%) and clove (6.9%). Crude fiber and ash contents ranged from 6.36 to 23.6% and from 3.57 to 7.1%, respectively. Table 1 shows the obtained results. Kochhar et al. [6] and El Nasri and El Tinay [7] reported that fat, protein, and fiber content of fenugreek seeds ranged from 6.53% to 7.1%, 24.4% to 25.8%, and 6.28% to 9.3%, respectively.

On the other hand, Ildik�� et al. [12] found that mustard seeds contain 28�C32% fat and 28�C36% proteins. Gokavi et al. [9], mentioned that cress seeds contain fat, protein and fiber of 27.5, 22.5, and 30%, respectively. It has also been reported that black cumin had 30�C40% fat, 20�C30% protein, 3.7�C4.7% ash, while the protein and fat contents of black pepper ranged from 11�C14 and 47�C53%, respectively, as reported by Jayashree et al. [19]. Moreover, clove contains 20% fat, 5.98% protein, 34.2% fiber, and 5.88% ash [10].Table 1Chemical composition (%) of cress, mustard, black cumin, fenugreek, black pepper, and clove seeds.The low percentage of moisture in cress and black cumin as compared to the others may increase the shelf life of these spices during packaging and storage.

They also limit fungal and contamination effects. Data presented in Table 2 shows the mineral contents of the different seeds under investigation. It could be noticed that all seeds contains higher levels of potassium (ranged from 383 to 823mg/100g) followed by calcium (ranged from 75 to 270mg/100g), magnesium (ranged from 42 to 102mg/100g), and iron (ranged from 20.5 to 65mg/100g). However, zinc, manganese, and copper metals were found at lower levels. These results differed mainly in the amount of potassium, magnesium, calcium and iron, as compared to previous results obtained by Nergiz and Otles [28], for black cumin and fenugreek seeds (El-Mahdy, and El-Sebaiy [29]). However, Gokavi et al. [9] found that cress seeds contain 1193mg/100g potassium.

While, clove seeds contain high levels of potassium (1102mg/100g) and magnesium (268mg/100g) as reported by Milind and Deepa [24]. The differences in the results obtained and that reported in previous studies may be due to environmental factors that prevail in production areas, cultivars used to produce seeds and Cilengitide also due to the different methods used to prepare these local spices.Table 2Mineral content (mg/100g) of cress, mustard black cumin, fenugreek, black pepper, and clove seeds.
