Study of Histamine Forming Bacteria in Commercial fish samples of Kalyan city
Histamine food poisoning is found to be associated with consumption of scombroid fish containing unusually high levels of histamine. Fish belonging to non-scombroid group may also cause histamine poisoning. In this study, histamine forming bacteria in the commercial fish samples of local markets of Kalyan region were investigated. Among 54 isolates 24 were found to be prominent histamine producers. A simple and rapid colorimetric method for the quantification of histamine in fish was used. Histamine level in fresh mackerel samples was found to be around 20 mg/100 g, which was much above the defect action level (5 mg/100 g) given by FDA indicating potential risk for histamine poisoning. The study suggest that practice of more hygienic and sanitary conditions during handling and processing of fish are required to minimize the contamination of such histamine producing bacteri
The common and uncommon cestodal infestation encountered in routine histopathological practice from a semi-urban population in south India and their public health importance.
Parasites are encountered uncommonly in routine histopathologic practice. Among them, cestodes form a major bulk. Cysticercosis heads the list forming the bulk of cases followed by Hydatidosis and Sparganosis. Microscopic identification of inflammation with surrounding reactions along with other morphological features forms the mainstay of diagnosis of parasitic diseases on histopathology. Identification of the parasites on histopathological examination would reduce the cost-diagnosis ratio avoiding expensive serological investigation

The leading sector can ascendant to economic structured change. The process of change in the economic structure characterized by, the decline in the share of the primary sector, the increase in the share of the secondary sector and the share of the tertiary sector. The purpose of the analyze is identify of the leading sector and the shift of economic structure change at Regency Kepulauan Meranti period 2008-2012. The analytical tool used is the shift fshare analysis (SS) and the method of location quotient (LQ). The data used are secondary data obtained from the Central Statistics Agency. Observational result that becomes to leading sector at Kepulauan Meranti regency with migas which is agricultural sector, processing industry, electricity, gas and fresh water, commerce, hotel and restaurant. Meanwhile without migas which is agricultural sector and commerce, hotel and restaurant. The economic structure in Kepulauan Meranti regency has shifted from the primary sector to the secondary sector, although the rate of shifts is still relatively small, characterized by the percentage contribution of the primary sector has declined, while the contribution of the secondary sector and the tertiary increased
Pendapatan dan Kesejahteraan Anggota Ksp Tani Makmur Kecamatan Natar Kabupaten Lampung Selatan
This research aimed to analyze cassava farming income received by members, the cooperative economic benefits received by members, revenue structure of farm household of KSP Tani Makmur members, and the level of welfare of members of KSP Tani Makmur. This research was conducted in KSP Tani Makmur, Natar Sub-district South Lampung District, in which total members were 32 cassava farmers. The data analysis was analysis of income, cooperative economic benefit analysis, analysis of household income, and analysis of the level of well-being according to BPS 2007. The result showed that the income of cassava farmers was on high level category with the highest contribution from cassava on farming. Based on average income per capita, the income of farmers was already above the poverty line. The economic advantages of indirect cooperative which was received by members still relatively low. While the direct economic advantage in form of fertilizers loans becoming an active member motivation in cooperative. The revenue structure of cassava farmer obtained from various sources. Those were cassava, yard, livestock, farm workers, trader, head of villagers, and cooperative. The level of farmers' welfare based on BPS method in 2007, we got the result that all the farmer members fit into the category of being wellfare
Comments on worldsheet theories dual to free large N gauge theories
We continue to investigate properties of the worldsheet conformal field
theories (CFTs) which are conjectured to be dual to free large N gauge
theories, using the mapping of Feynman diagrams to the worldsheet suggested in
hep-th/0504229. The modular invariance of these CFTs is shown to be built into
the formalism. We show that correlation functions in these CFTs which are
localized on subspaces of the moduli space may be interpreted as delta-function
distributions, and that this can be consistent with a local worldsheet
description given some constraints on the operator product expansion
coefficients. We illustrate these features by a detailed analysis of a specific
four-point function diagram. To reliably compute this correlator we use a novel
perturbation scheme which involves an expansion in the large dimension of some
operators.Comment: 43 pages, 16 figures, JHEP format. v2: added reference
The Effective Particle-Hole Interaction and the Optical Response of Simple Metal Clusters
Following Sham and Rice [L. J. Sham, T. M. Rice, Phys. Rev. 144 (1966) 708]
the correlated motion of particle-hole pairs is studied, starting from the
general two-particle Greens function. In this way we derive a matrix equation
for eigenvalues and wave functions, respectively, of the general type of
collective excitation of a N-particle system. The interplay between excitons
and plasmons is fully described by this new set of equations. As a by-product
we obtain - at least a-posteriori - a justification for the use of the TDLDA
for simple-metal clusters.Comment: RevTeX, 15 pages, 5 figures in uufiles format, 1 figure avaible from

Geochemistry of reduced inorganic sulfur, reactive iron, and organic carbon in fluvial and marine surface sediment in the Laizhou Bay region, China
Understanding the geochemical cycling of sulfur in sediments is important because it can have implications for both modern environments (e.g., deterioration of water quality) and interpretation of the ancient past (e.g., sediment C/S ratios can be used as indicators of palaeodepositional environment). This study investigates the geochemical characteristics of sulfur, iron, and organic carbon in fluvial and coastal surface sediments of the Laizhou Bay region, China. A total of 63 sediment samples were taken across the whole Laizhou Bay marine region and the 14 major tidal rivers draining into it. Acid volatile sulfur, chromium (II)-reducible sulfur and elemental sulfur, total organic carbon, and total nitrogen were present in higher concentrations in the fluvial sediment than in the marine sediment of Laizhou Bay. The composition of reduced inorganic sulfur in surface sediments was dominated by acid volatile sulfur and chromium (II)-reducible sulfur. In fluvial sediments, sulfate reduction and formation of reduced inorganic sulfur were controlled by TOC and reactive iron synchronously. High C/S ratios in the marine sediments indicate that the diagenetic processes in Laizhou Bay have been affected by rapid deposition of sediment from the Yellow River in recent decades
Bi-allelic GAD1 variants cause a neonatal onset syndromic developmental and epileptic encephalopathy.
Developmental and epileptic encephalopathies are a heterogeneous group of early-onset epilepsy syndromes dramatically impairing neurodevelopment. Modern genomic technologies have revealed a number of monogenic origins and opened the door to therapeutic hopes. Here we describe a new syndromic developmental and epileptic encephalopathy caused by bi-allelic loss-of-function variants in GAD1, as presented by 11 patients from six independent consanguineous families. Seizure onset occurred in the first 2 months of life in all patients. All 10 patients, from whom early disease history was available, presented with seizure onset in the first month of life, mainly consisting of epileptic spasms or myoclonic seizures. Early EEG showed suppression-burst or pattern of burst attenuation or hypsarrhythmia if only recorded in the post-neonatal period. Eight patients had joint contractures and/or pes equinovarus. Seven patients presented a cleft palate and two also had an omphalocele, reproducing the phenotype of the knockout Gad1-/- mouse model. Four patients died before 4 years of age. GAD1 encodes the glutamate decarboxylase enzyme GAD67, a critical actor of the γ-aminobutyric acid (GABA) metabolism as it catalyses the decarboxylation of glutamic acid to form GABA. Our findings evoke a novel syndrome related to GAD67 deficiency, characterized by the unique association of developmental and epileptic encephalopathies, cleft palate, joint contractures and/or omphalocele
On the Corrections to Dashen's Theorem
The electromagnetic corrections to the masses of the pseudoscalar mesons
and are considered. We calculate in chiral perturbation theory the
contributions which arise from resonances within a photon loop at order . Within this approach we find rather moderate deviations to Dashen's
theorem.Comment: 14 pages, sligthly enlarged version; a numerical error is corrected
and the embedding of the figures is improved. The complete paper, including
