Effects of root and foliar treatments of carrot plants with lead and cadmium on the growth, uptake and the distribution of uptake of metals in treated plants

Abstract: Toxicity of cadmium and lead on the growth of carrot plants has been studied. Cadmium has been found to be more toxic than lead especially on the shoots of carrot plants. Foliar treatment has been compared with root‐treatment for the two elements on carrots and on their roots and shoots. Concentrations and total contents of lead and cadmium in whole plant in roots and in shoots have been determined for treated carrot plants and compared in root‐treatment with foliar‐treatment. Explanations have been suggested whenever possible to illucidate the results obtained. Percentages of the metals taken by plants from the whole amounts of metal added during treatment have been calculated and related to type of metal used, concentration of metal in solutions used for treatment and the way of treatment.

Reduction in unnecessary ventricular pacing fails to affect hard clinical outcomes in patients with preserved left ventricular function: a meta-analysis

Abstract: Aims: Several pacing modalities across multiple manufacturers have been introduced to minimize unnecessary right ventricular pacing We conducted a meta-analysis to assess whether ventricular pacing reduction modalities (VPRM) influence hard clinical outcomes in comparison to standard dual-chamber pacing (DDD) Methods and results: An electronic search was performed using Cochrane Central Register, PubMed, Embase, and Scopus Only randomized controlled trials (RCT) were included in this analysis Outcomes of interest included: frequency of ventricular pacing (VP), incident persistent/permanent atrial fibrillation (PerAF), all-cause hospitalization and all-cause mortality Odds ratios (OR) were reported for dichotomous variables Seven RCTs involving 4119 adult patients were identified Ventricular pacing reduction modalities were employed in 2069 patients: (MVP, Medtronic Inc) in 1423 and (SafeR, Sorin CRM, Clamart) in 646 patients Baseline demographics and clinical characteristics were similar between VPRM and DDD groups The mean follow-up period was 25 ± 09 years Ventricular pacing reduction modalities showed uniform reduction in VP in comparison to DDD groups among all individual studies The incidence of PerAF was similar between both groups {8 vs 10%, OR 084 [95% confidence interval (CI) 057; 124], P = 038} Ventricular pacing reduction modalities showed no significant differences in comparison to DDD for all-cause hospitalization or all-cause mortality [9 vs 11%, OR 082 (95% CI 065; 103), P= 009; 6 vs 6%, OR 097 (95% CI 074; 128), P = 084, respectively] Conclusion: Novel VPRM measures effectively reduce VP in comparison to standard DDD When actively programmed, VPRM did not improve clinical outcomes and were not superior to standard DDD programming in reducing incidence of PerAF, all-cause hospitalization, or all-cause mortality

Keratinophilic fungi on sheep hairs from the West Bank of Jordan.

Abstract: The mycoflora of the hair in 285 sheep from the West Bank of Jordan was analysed and the frequency of occurrence and the relative importance value for different fungal species found were calculated. Ninety six species which belong to 36 genera were isolated. Forty one of these species were either well-known agents of animal and human mycoses (Trichophyton verrucosum, T. mentagrophytes, Microsporum nanum, M. canis, and others), or have been isolated from human and animal lesions (Arthroderma cuniculi, A. curreyi, Chrysosporium tropicum, Acremonium kiliense, Aphanoascus fulvuscens, Aspergillus versicolor, Paecilomyces lilacinus, Scopulariopsis brevicaulis, and others). These pathogenic fungi comprised 75.4% of all fungi recovered from the hair of sheep. This animal seems to represent an adequate reservoir for several dermatophytes and several potentially pathogenic fungi.

Antidiabetic and protective effects of the aqueous extract of Arbutus unedo L. in streptozotocin-nicotinamide-induced diabetic mice.

Abstract: Abstract Background Diabetes mellitus (DM) is currently a major health problem and the most common chronic disease worldwide. Traditional medicinal plants remedies remain a potential adjunct therapy to maintain better glycemic control while also imparting few side-effects. Arbutus unedo L. has been traditionally used to manage several diseases including diabetes. This study was undertaken to contribute the validation of the traditional use of Arbutus unedoL. (Ericaceae) in the treatment of diabetes. Methods In-vitro antidiabetic effect of the A. unedo roots aqueous extract was conducted using α-glucosidase and α-amylase assays. While in-vivo antidiabetic activity was conducted using streptozotocin-nicotinamide (STZ-NA) induced diabetic mice. Diabetic animals were orally administered the aqueous extract in 500 mg/kg of body weight to assess the antidiabetic effect. The blood glucose level and body weight of the experimental animals were monitored for 4 weeks. In addition, the histopathological examination of the treated mice pancreas was also conducted to observe the changes of β-cells during the treatment process. Results The extract produced a significant decrease in blood glucose level in diabetic mice. This decrease was equivalent to that which observed in mice treated with a standard after 2–4 weeks. In addition, the plant extract exhibited a potent inhibitory effect on α-amylase and α-glucosidase activity with IC50 values of 730.15±0.25 μg/mL and 94.81±5.99 μg/mL, respectively. Moreover, the histopathologic examination of the pancreas showed a restoration of normal pancreatic islet cell architecture which observed in the diabetic mice treated with plant extract. Conclusions The aqueous A. unedo roots extract has a significant in vitro and in vivo antidiabetic effects and improves metabolic alterations. The revealed results justify its traditional medicinal use.
