Determination of Some Essential Metals in Selected Medicinal Plants
Medicinal plants are sources of different essential metals that have different biological activities including those useful in the treatment of human diseases. Among the indigenous medicinal plants used as phytomedicines for the treatment of many diseases in Kano State are Annona squamosa, Psidium guajava, Anacardium occidentale, Ficussycomorus and Pomegranate. The aim of this study was to determine the levels of essential metals present in the herb tissues (leaf and stem) samples obtained from Kwarin Gogau garden, airport road, Kano State. The plant samples were collected, pretreated and digested by wet digestion method and analyzed using Micro Plasma Atomic Emission Spectrophotometer (MPAES). The results obtained in this study showed that extracts of the medicinal herbs investigated contained essential metals. The mean concentrations range for essential metals were: Zn (0.109-0.658mg/kg), Cu (0.026-0.079 mg/kg), K (1.846 -11.669 mg/kg), Mn (0.039-1.269 mg/kg), Fe (0.019-0.107mg/kg), Ni (0.054-0.144 mg/kg). Comparing the results obtained with the permissible limits set by WHO for consumed medicinal herbs, it was concluded that the essential metals present in the herbs were below permissible limits. Also, there was no statistically significant difference between the plant tissues samples analyzed for Zn, Cu, K, Mn, Fe, and Ni (P>0.05).
 
Effectiveness of aqueous leaf extract of Peperomia pellucida and Terminalia catappa in the management of cyst nematode (Heterodera sacchari) on selected rice varieties
Experiments were conducted
at the teaching and research farm of Faculty
of Agriculture, University of Ilorin, Nigeria
to determine the effect of aqueous extract of
Peperomia pelliucida and Terminalia
catappa on the management of cyst
nematode, Heterodera sacchari on some
selected rice varieties. A screenhouse
preliminary study was first carried out in
December, 2014 to assess the pathogenicity
of H. sacchari on ten varieties of rice from
which five varieties were selected for field
trials. The five selected rice varieties were
grown on soil inoculated with cysts of
H. sacchari. The field experiment was a 5x3
factorial type fitted into a randomized
complete block design (RCBD). Soil
nematode population, physiochemical soil
analysis and phytochemical screening of the
tests plants were carried out. Treatment
application of aqueous leaf extract were
conducted at the 2nd and 7th weeks after
transplanting. Data were collected on the
plant height, shoot, root weights, yield and
soil nematode population. All numerical
data were subjected to analysis of variance
(Anova) using GENSTAT statistical
package 12th edition and where significant
differences were observed, means were
separated using fisherâs protected LSD.
Results from the study revealed that
treatment combination of P. pellucida and
T. catappa singly with FARO 60, FARO 61,
and NERICA 8 performed significantly
higher (p>0.05) than the other rice varieties
for most of the growth and yield parameter
measured. Significant differences occurred
between shoot, root, and yield weight of
treated plants and their control counterparts.
There was no significant difference between
the two plant extracts used with respect to
parameters measured. Treated plants
performed significantly higher than the
control. Based on the results of the study,
paddy farmers experiencing H. sacchari
infestation are encouraged to treat the field
with P. pellucida and or T. catappa,
especially when planting FARO 60, FARO
61, and NERICA 8 as these combinations
promise to give higher yield
Evaluation of the nematicidal and antifungal activity of aqueous extracts of Moringa oleifera leaves and seed in cucumber field
This aim of the two-year
study was to evaluate the nematicidal and
antifungal activity of Moringa oleifera
extracts against Meloidogyne incognita
and fungi infestation in cucumber field.
The aqueous extracts of leaves and seeds
of M. oleifera were used to treat the
plants. The findings of the present study
revealed that the plant extracts were
active against the test pathogens. All
treated plants were significantly higher
than the control with respect to number of
leaves and branches, vine length, fruit
weight, and yield. Of the two varieties of
cucumber used, combination of cucumber
market with moringa aqueous leaf
extracts gave higher results. The phytochemical
screening revealed the presence
of alkaloids, flavonoids, glycosides,
saponins, and tannins. These possess
nematicidal and antifungal activities.
Combination of variety 2, Market More
with Moringa leaves aqueous extract is
being recommended to farmers for
management of nematode and fungal
diseases. Organic amendments have the
advantage of controlling environmental
effluence
A Rare Case of Propofol-Induced Acute Liver Failure and Literature Review
The incidence of drug-induced acute liver failure is increasing. A number of drugs can inhibit mitochondrial functions, alter ÎČ-oxidation and cause accumulation of free fatty acids within the hepatocytes. This may result in hepatic steatosis, cell death and liver injury. In our case, propofol, an anesthetic drug commonly used in adults and children, is suspected to have induced disturbance of the mitochondrial respiratory chain, which in consequence led to insufficient energy supply and finally liver failure. We report the case of a 35-year-old Caucasian woman with acute liver failure after anesthesia for stripping of varicose veins. Liver histology, imaging and laboratory data indicate drug-induced acute liver failure, presumably due to propofol. Hepatocyte death and microvesicular fatty degeneration of 90% of the liver parenchyma were observed before treatment with steroids. Six months later, a second biopsy was performed, which revealed only minimal steatosis and minimal periportal hepatitis. We suggest that propofol led to impaired fatty acid oxidation possibly due to a genetic susceptibility. This caused free fatty acid accumulation within hepatocytes, which presented as hepatocellular fatty degeneration and cell death. Large scale hepatocyte death was followed by impaired liver function and, consecutively, progressed to acute liver failure
Study of ground and excited state decays in N approximate to Z Ag nuclei
4 pags., 4 figs. -- CGS15 â Capture Gamma-Ray Spectroscopy and Related TopicsA decay spectroscopy experiment was performed within the EURICA campaign at RIKEN in 2012. It aimed at the isomer and particle spectroscopy of excited states and ground states in the mass region below the doubly magic 100Sn. The N = Z nuclei 98In, 96Cd and 94Ag were of particular interest for the present study. Preliminary results on the neutron deficient nuclei 93Ag and 94Ag are presented. In 94Ag a more precise value for the half-life of the ground stateâs superallowed Fermi transition was deduced. In addition the energy spectra of the mentioned decay could be reproduced through precise Geant4 simulations of the used active stopper SIMBA. This will enable us to extract QÎČ values from the measured data. The decay of 93Ag is discussed based on the observed implantation-decay correlation events.This work was carried out at the RIBF operated by RIKEN

The role of core excitations in the structure and decay of the 16+ spin-gap isomer in 96Cd
The first evidence for ÎČ-delayed proton emission from the 16+ spin gap isomer in 96Cd is presented. The data were obtained from the Rare Isotope Beam Factory, at the RIKEN Nishina Center, using the BigRIPS spectrometer and the EURICA decay station. ÎČp branching ratios for the ground state and 16+ isomer have been extracted along with more precise lifetimes for these states and the lifetime for the ground state decay of 95Cd. Large scale shell model (LSSM) calculations have been performed and WKB estimates made for â=0,2,4 proton emission from three resonance-like states in 96Ag, that are populated by the ÎČ decay of the isomer, and the results compared to the new data. The calculations suggest that â=2 proton emission from the resonance states, which reside âŒ5 MeV above the proton separation energy, dominates the proton decay. The results highlight the importance of core-excited wavefunction components for the 16+ state
Galaxy Clusters Associated with Short GRBs. II. Predictions for the Rate of Short GRBs in Field and Cluster Early-Type Galaxies
We determine the relative rates of short GRBs in cluster and field early-type
galaxies as a function of the age probability distribution of their
progenitors, P(\tau) \propto \tau^n. This analysis takes advantage of the
difference in the growth of stellar mass in clusters and in the field, which
arises from the combined effects of the galaxy stellar mass function, the
early-type fraction, and the dependence of star formation history on mass and
environment. This approach complements the use of the early- to late-type host
galaxy ratio, with the added benefit that the star formation histories of
early-type galaxies are simpler than those of late-type galaxies, and any
systematic differences between progenitors in early- and late-type galaxies are
removed. We find that the ratio varies from R(cluster)/R(field) ~ 0.5 for n =
-2 to ~ 3 for n = 2. Current observations indicate a ratio of about 2,
corresponding to n ~ 0 - 1. This is similar to the value inferred from the
ratio of short GRBs in early- and late-type hosts, but it differs from the
value of n ~ -1 for NS binaries in the Milky Way. We stress that this general
approach can be easily modified with improved knowledge of the effects of
environment and mass on the build-up of stellar mass, as well as the effect of
globular clusters on the short GRB rate. It can also be used to assess the age
distribution of Type Ia supernova progenitors.Comment: ApJ accepted versio
Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.
