Rural Employment Diversification in India: Trends, Determinants and Implications on Poverty
This paper has studied rural employment diversification in India and across major states using NSSO data at household level for the period 1983 and 2009-10. Factors affecting rural employment diversification towards non-farm sector have also been studied. Analysis has shown that the non-farm sector has consistently grown over time and employed nearly one-third of the rural workforce in 2009-10, as compared to merely one-fifth in 1983 at all-India level. The similar trend is seen across major states as well, though the pace and pattern varied widely. In providing employment to rural workforce, increasing dominance of crop production, followed by animal husbandry was observed across major states during 2009-10. The share of fishery and forestry was negligible in providing employment to the rural workforce. The study has revealed that the increasing rural non-farm employment has positive and significant effect on reducing rural poverty at all-India level. A positive link between income and employment has also been observed in diversifying towards horticultural activities. A well designed area-specific programme should be evolved to help improve skill of rural workforce, which in turn would benefit in getting employment in the non-farm sector.Rural employment, Employment diversification, Crop sector, Agricultural and Food Policy, J21, J23, O15, O18,

Methionyl-tRNA formyltransferase utilizes 10-formyldihydrofolate as an alternative substrate and impacts antifolate drug action
Methionyl-tRNA formyltransferase (Fmt)-mediated formylation of Met-tRNAfMet to fMet-tRNAfMet is crucial for efficient initiation of translation in bacteria and the eukaryotic organelles. Folate dehydrogenase-cyclohydrolase (FolD), a bifunctional enzyme, carries out conversion of 5,10-methylene tetrahydrofolate (5,10-CH2-THF) to 10-formyl-THF (10-CHO-THF), a metabolite utilized by Fmt as a formyl group donor. In this study, using in vivo and in vitro approaches, we show that 10-CHO-DHF may also be utilized by Fmt as an alternative substrate (formyl group donor) to formylate Met-tRNAfMet. Dihydrofolate (DHF) formed as a by-product in the in vitro assay was verified by LC-MS/MS analysis. FolD-deficient mutants and Fmt over-expressing strains were more sensitive to trimethoprim (TMP) than the ∆fmt strain, suggesting that the domino effect of TMP leads to inhibition of protein synthesis and strain growth. Antifolate treatment to
Escherichia coli
showed a decrease in the reduced folate species (THF, 5,10-CH2-THF, 5-CH3-THF, 5,10-CH+-THF and 5-CHO-THF) and increase in the oxidized folate species (folic acid and DHF). In cells, 10-CHO-DHF and 10-CHO-folic acid were enriched in the stationary phase. This suggests that 10-CHO-DHF is a bioactive metabolite in the folate pathway for generating other folate intermediates and fMet-tRNAfMet.</jats:p

Health Guard Measures of Ayurveda Against Climatic Variation- A Review
Human body has a compact systemic organisation of different tissues and organs which is managed by well specified metabolic and homeostatic mechanisms having sensitivity regarding it surroundings microscopically as well as macroscopically. It gets affected by the things around it either inside or outside. Hence while discussing its lives the environment or the climate where it lives comprises great aspect to mention so that appropriate measures regarding maintenance of health conditions can be analysed accordingly. As it has to be seen that the persons fallowing their health monitoring daily regimens also tends to attain several health discomfort or disorders while seen any change the climatic conditions where they live. So, the climatic variations measures to be great factor for human lives. That is why there are several rules and regimens regarding climatic variations are advised since very past time. In Ayurveda it is called as Ritucharya, the Charya or regimens mint for different Ritus or seasons. According to the Ayurveda there are total six seasons (Ritus) in one year and the body needs to adapt itself according to the seasonal variation to remain healthy. But whenever fails to adopt or fails to attain the compulsory consequence results in deformitie
Rural Employment Diversification in India: Trends, Determinants and Implications on Poverty
This paper has studied rural employment diversification in India and across major states using NSSO data
at household level for the period 1983 and 2009-10. Factors affecting rural employment diversification
towards non-farm sector have also been studied. Analysis has shown that the non-farm sector has
consistently grown over time and employed nearly one-third of the rural workforce in 2009-10, as compared
to merely one-fifth in 1983 at all-India level. The similar trend is seen across major states as well, though the
pace and pattern varied widely. In providing employment to rural workforce, increasing dominance of crop
production, followed by animal husbandry was observed across major states during 2009-10. The share of
fishery and forestry was negligible in providing employment to the rural workforce. The study has revealed
that the increasing rural non-farm employment has positive and significant effect on reducing rural poverty
at all-India level. A positive link between income and employment has also been observed in diversifying
towards horticultural activities. A well designed area-specific programme should be evolved to help improve
skill of rural workforce, which in turn would benefit in getting employment in the non-farm sector
Impact of Mutating the Key Residues of a Bifunctional 5,10-Methylenetetrahydrofolate Dehydrogenase-Cyclohydrolase from <i>Escherichia coli</i> on Its Activities
Methylenetetrahydrofolate dehydrogenase-cyclohydrolase
(FolD) catalyzes
interconversion of 5,10-methylene-tetrahydrofolate and 10-formyl-tetrahydrofolate
in the one-carbon metabolic pathway. In some organisms, the essential
requirement of 10-formyl-tetrahydrofolate may also be fulfilled by
formyltetrahydrofolate synthetase (Fhs). Recently, we developed an <i>Escherichia coli</i> strain in which the <i>folD</i> gene was deleted in the presence of <i>Clostridium perfringens
fhs</i> (<i>E. coli</i> Δ<i>folD</i>/p-<i>fhs</i>) and used it to purify FolD mutants (free
from the host-encoded FolD) and determine their biological activities.
Mutations in the key residues of <i>E. coli</i> FolD, as
identified from three-dimensional structures (D121A, Q98K, K54S, Y50S,
and R191E), and a genetic screen (G122D and C58Y) were generated,
and the mutant proteins were purified to determine their kinetic constants.
Except for the R191E and K54S mutants, others were highly compromised
in terms of both dehydrogenase and cyclohydrolase activities. While
the R191E mutant showed high cyclohydrolase activity, it retained
only a residual dehydrogenase activity. On the other hand, the K54S
mutant lacked the cyclohydrolase activity but possessed high dehydrogenase
activity. The D121A and G122D (in a loop between two helices) mutants
were highly compromised in terms of both dehydrogenase and cyclohydrolase
activities. <i>In vivo</i> and <i>in vitro</i> characterization of wild-type and mutant (R191E, G122D, D121A, Q98K,
C58Y, K54S, and Y50S) FolD together with three-dimensional modeling
has allowed us to develop a better understanding of the mechanism
for substrate binding and catalysis by <i>E. coli</i> FolD
A Genetic Analysis of the Functional Interactions within Mycobacterium tuberculosis Single-Stranded DNA Binding Protein
Single-stranded DNA binding proteins (SSBs) are vital in all organisms. SSBs of Escherichia coli (EcoSSB) and Mycobacterium tuberculosis (MtuSSB) are homotetrameric. The N-terminal domains (NTD) of these SSBs (responsible for their tetramerization and DNA binding) are structurally well defined. However, their C-terminal domains (CTD) possess undefined structures. EcoSSB NTD consists of beta 1-beta 1'-beta 2-beta 3-alpha-beta 4-beta 45(1)-beta 45(2)-beta 5 secondary structure elements. MtuSSB NTD includes an additional beta-strand (beta 6) forming a novel hook-like structure. Recently, we observed that MtuSSB complemented an E. coli Delta ssb strain. However, a chimeric SSB (m beta 4-beta 5), wherein only the terminal part of NTD (beta 4-beta 5 region possessing L-45 loop) of EcoSSB was substituted with that from MtuSSB, failed to function in E. coli in spite of its normal DNA binding and oligomerization properties. Here, we designed new chimeras by transplanting selected regions of MtuSSB into EcoSSB to understand the functional significance of the various secondary structure elements within SSB. All chimeric SSBs formed homotetramers and showed normal DNA binding. The m beta 4-beta 6 construct obtained by substitution of the region downstream of beta 5 in m beta 4-beta 5 SSB with the corresponding region (beta 6) of MtuSSB complemented the E. coli strain indicating a functional interaction between the L-45 loop and the beta 6 strand of MtuSSB
