Abstract
Microbial biostimulants (MBs) promote plant growth and stress tolerance in a sustainable manner. However, precise field trials of MBs are required in natural setting with a range of crop varieties to harness the benefits of biostimulants on crop yield improvement. This study investigated the effects of two MBs, Trichoderma album and Bacillus megaterium, on an onion cultivar's growth, nutritional qualities, antioxidant properties, and yield potentials under field conditions for two successive years. Before transplantation, onion bulbs were gelatin-coated with 2.0 and 4.0 g L-1 of each of the MB. Results revealed that MBs-pretreated onion plants exhibited better growth indices, photosynthetic pigment contents, and yield-attributing features like bulb weight than control plants. Nutraceutical analysis demonstrated that T. album-pretreated (by 2.0 g L-1) onion cultivar enhanced the level of K+ (by 105.79%), Ca2+ (by 37.77%), proline (by 34.21%), and total free amino acids (by 144.58%) in bulb tissues over the control plants. Intriguingly, the pretreatment with both T. album and B. megaterium (by 2.0 g L-1) increased the levels of total soluble carbohydrates (by 19.10 and 84.02%), as well as antioxidant properties, including increased activities of superoxide dismutase (by 58.52 and 31.34%), catalase (by 164.71 and 232%), ascorbate peroxidase (by 175.35 and 212.69%), and glutathione-S-transferase (by 31.99 and 9.34%) and improved the contents of ascorbic acid (by 19.1 and 44.05%), glutathione (by 6.22 and 33.82%), and total flavonoids (by 171.98 and 56.24%, respectively) in the bulb tissues than control plants. Although both MBs promoted the growth and nutraceutical qualities of onion bulbs, T. album pretreatment showed better effects than that of B. megaterium in the field settings. Based on the morphophysiological attributes and biochemical properties, a low dose (2.0 g L-1) was more effective than a high dose (4.0 g L-1) of T. album in promoting onion growth. Overall, the current research findings imply that T. album might be a potential MB in improving growth and quality attributes, and hence the productivity of onion cultivars under field circumstances.

Abstract
The increasing culinary use of onion (Alium cepa) raises pressure on the current production rate, demanding sustainable approaches for increasing its productivity worldwide. Here, we aimed to investigate the beneficial effects of licorice (Glycyrrhiza glabra) root extract (LRE) in improving growth, yield, nutritional status, and antioxidant properties of two high-yielding onion cultivars, Shandaweel and Giza 20, growing under field conditions in two consecutive years. Our results revealed that pretreatments of both onion cultivars with LRE exhibited improved growth indices (plant height and number of leaves) and yield-related features (bulb length, bulb diameter, and bulb weight) in comparison with the corresponding LRE-devoid control plants. Pretreatments with LRE also improved the nutritional and antioxidant properties of bulbs of both cultivars, which was linked to improved mineral (e.g., K+ and Ca2+) acquisition, and heightened activities of enzymatic antioxidants (e.g., superoxide dismutase, catalase, ascorbate peroxidase, glutathione peroxidase, and glutathione S-transferase) and increased levels of non-enzymatic antioxidants (e.g., ascorbic acid, reduced glutathione, phenolics, and flavonoids). LRE also elevated the contents of proline, total free amino acids, total soluble carbohydrates, and water-soluble proteins in both onion bulbs. In general, both cultivars displayed positive responses to LRE pretreatments; however, the Shandaweel cultivar performed better than the Giza 20 cultivar in terms of yield and, to some extent, bulb quality. Collectively, our findings suggest that the application of LRE as biostimulant might be an effective strategy to enhance bulb quality and ultimately the productivity of onion cultivars under field conditions.

Abstract
AIMS The aim of this study was to isolate and characterize staphylococcal isolates from diabetic foot ulcers (DFU) in Jordanian patients. METHODS AND RESULTS Selected aerobic pathogens recovered from DFU specimens and patients' nares with a focus on staphylococci were investigated. Antimicrobial susceptibilities and the prevalence of methicillin-resistant staphylococci (MRS) were determined. SCCmec types and toxigenic characteristics were analysed and spa typing was performed for methicillin-resistant Staphylococcus aureus (MRSA) isolates. The relationship between toxigenic characteristics of MRSA and the Wagner ulcer grading system was statistically analysed. A total number of 87 DFU patients were recruited for the study. The DFU cultures were polymicrobial. Members of the genus Staphylococcus were the most common among DFU-associated isolates found in 48·3% (n = 42) of all patients enrolled. Coagulase-negative staphylococci (CoNS) comprised 63·3% of staphylococci isolated from DFUs predominated by Staphylococcus epidermidis in both DFU (7·6%) and nares (39·2%). Staphylococcus aureus was isolated from DFUs and nares in 14·2 and 9·8%, respectively, while 93 and 70% of these isolates were MRSA. Most of MRSA carried SCCmec type IV (76·2%) while SCCmec elements were non-typeable in most methicillin resistant coagulase negative staphylococci (MR-CoNS) (61·9%). The most frequent MRSA spa type was t386 (23·8%). Most MRSA and MR-CoNS exhibited resistance towards aminoglycosides, fluoroquinolones and macrolides and susceptibility towards vancomycin, mupirocin and linezolid. No association was found between the possession of pvl, tst, sea and hlg toxins and Wagner ulcer grading system (P value >0·05). CONCLUSIONS This analysis of Jordanian DFU culture demonstrated its polymicrobial nature with predominance of Staphylococcus sp. SIGNIFICANCE AND IMPACT OF THE STUDY This study is the first of its type to assess the microbiology of DFU among Jordanian patients. The results will help in the appropriate application of antimicrobial chemotherapy in the management of DFU.

Abstract
Magnetic fields are an unavoidable physical factor affecting living organisms. Lettuce seeds (Lactuca sativa var. cabitat L.) were subjected to various intensities of the static magnetic field (SMF) viz., MF0 (control), SMF1 (0.44 Tesla (T), SMF2 (0.77 T), and SMF3 (1 T) for three exposure times (1, 2, and 3 h). SMF-treated seedlings showed induction in growth parameters and metabolism comparing to control. All photosynthetic pigments were induced markedly under SMF, especially chlorophyll a. SMF at different intensities boosted osmolytes, non-enzymatic antioxidants, and the phenylalanine ammonia-lyase activity over non-magnetized seedlings. Oxidative damage criteria viz., hydrogen peroxide, superoxide radical, and lipid peroxidation, as well as polyphenol oxidase activity, were kept at low values under SMF-treated seeds relative to control, especially SMF2. Electron donors to antioxidant enzymes including nitrate reductase, nitric oxide, and hydrogen sulfide induced via SMF exposure and consequently the activities of superoxide dismutase, glutathione-S-transferases, catalase, and peroxidases family enzymes were also stimulated under SMF, whatever the intensity or the exposure period applied. All these regulations reflected on the enhancement of lettuce yield production which reached 50% over the control at SMF3. Our findings offered that SMF-seed priming is an innovative and low-cost strategy that can improve the growth, bioactive constituents, and yield of lettuce.

Abstract
Fluazinam is a widely used fungicide; most of the available information associated with its impact predominately on birds, invertebrates, mammals, and algae and scarce works studied its impact on crop plants. A two years-field experiments were conducted to study the response of pepper and eggplant to fluazinam at 0, 1, 2, and 3 times of the fluazinam-recommended dose (0, 0.5, 1, and 1.5 mL/L). The results revealed that fluazinam did not cause toxic effect on the tested plants except for temporary decline of shoot weights and lengths after 3 days of fluazinam application. However, fluazinam improved the physiological status of leaves via promoting metabolites, antioxidants, better membrane integrity, and adjustment of the redox status of fluazinam-sprayed plants. The ultrastructure changes of fluazinam-treated leaves associated with increment of chloroplasts' starch granules, giant nucleus, and elevated number of mitochondria. After 35 days of treatments, plant length of fungicide-treated plants was found to be higher than control and flowering time showed significant earliness. Furthermore, the yield traits were increased significantly in response to fluazinam. Our findings suggested that fluazinam-treated plants could initiate an early defense mechanism to mitigate the permanent growth retardation. This study could serve as a matrix for further studies to seek elucidation of plants' response to other doses of fluazinam. Graphical abstract .

Abstract
Due to limited knowledge of graphene nanosheets (GNS) on phyto-biological studies, GNS was sprayed to pepper and eggplants during the seasons 2016 and 2017 at doses 0.1, 0.2 and 0.3 GNS g L-1 to assess their biosafety on leaf ultrastructure and agro-physiological traits. GNS was localized on plastids, cell walls and intercellular spaces of both plants. GNS-sprayed peppers characterized by giant chloroplasts with large starch granules and increment of mitochondrial number adjacent to chloroplasts. Whilst, chloroplast ultrastructure of GNS-treated eggplants appeared to be ellipsoidal-shaped with few normal sized-starch granules compared to control. The localization of GNS inside chloroplast may be activated photosynthetic pigments; thereby stimulation of fructose, sucrose and starch was displayed. The rising of hydrogen peroxide of GNS-treated leaves had beneficial role on triggering the activity of catalase, ascorbate peroxidase, glutathione peroxidase and glutathione-S-transferase. Furthermore, the reduction of hydroxyl radical and superoxide anion reflected the involvement of GNS in induction of antioxidant molecules and superoxide dismutase for modulating cell oxidative status. Thus, the lipid peroxidation and electrolyte leakage of GNS-treated plants were kept below the baseline of water-sprayed plants. Moreover, the promotions of health-promoting secondary metabolites via GNS aerosol were in close association to exacerbation of phenylalanine ammonialyase actvity. This study conclusively demonstrated that GNS did not have cytotoxic properties in pepper and eggplant cells rather healthy growth and promoted yield in the terms of number of branches plant-1, number of fruits plant-1 and fruit yield (ton hectare-1) were the net result of GNS-induced metabolic regulation of the leaves physiological status.

Abstract
This study aimed to estimate the status of serum vitamin B12 level in patients attending Jordan University Hospital in Amman, and to examine the relationship with demographic data, chronic illness, dietary habits, haematological parameters and symptoms related to vitamin B12 levels. A total of 838 patients completed a questionnaire and gave blood samples; 44.6% were vitamin B12 deficient (< 180 pg/mL) and 34.2% had hypovitaminosis (180-300 pg/mL). Vitamin B12 deficiency was associated with memory impairment, low meat intake and strict vegetarian (vegan) diets. The high frequency of low vitamin B12 warrants the development of a strategy to correct this problem in Jordan.
