The emergence of the oil welfare state: The case of Kuwait

Conclusion This essay provided an analytical account of the emergence and development of social welfare in the newly emerging oil-rich state of Kuwait, by delineating the particular historical conditions and socio-economic transformations which were responsible for giving this welfare state its particular structure.We relied on specific theoretical guidelines and concepts derived from the much honored holistic tradition in anthropology and political economy, as well as on formulations developed by scholars coming from the new tradition in the development approach in welfare studies.The analytical elucidation presented here indicates that a multiplicity of both internal and external factors and/or determinants have simultaneously influenced the development of the oil welfare state in Kuwait. The origins, nature, timing and interplay of all these factors appear to be specific and unique to the experience of Gulf societies, and have given rise to particular socio-political configurations and psychological effects. Thus the new soical welfare conditions which have emerged in modern Kuwait are different in many significant ways from those experienced in both the advanced industrial capitalist societies and Third World countries. Moreover, the economic, social, cultural and historical specificities of the oil-rich societies have made the overall development and the functions of the welfare state different from those found to be recurrent in advanced capitalist societies.It appears that, on one hand, the new oil welfare state has succeeded in modernizing life and bettering the human condition of its small population. Yet, on the other hand, this form of extensive oil-welfarism has in itself generated certain conditions which appear to have some-what weakened the capacities of these societies to achieve genuine development. In other words, it has failed to stimulate the development of productive social forces and other supportive infrastructural conditions from within society itself. A thorough analysis of these and other consequences which have become well embedded in the fabric of Kuwaiti society and culture requires and entirely separate paper.Sulayman Khalaf is Assistant Professor of Anthropology, Kuwait University.

Bacteria of public health significance in blackcurrant juice

A total of 192 samples of blackcurrant juice were investigated for hygienic quality and drug resistance. The average aerobic bacteria in 1 ml of the blackcurrant juice was 4.8 x 10(8) and the average MPN was 8.4 x 10(2) coliform/100 ml. The percentage of the samples contaminated with coliform bacteria was 23.4. The incidence of Escherichia coli, Klebsiella, Pseudomonas aeruginosa, Staphylococcus aureus and faecal streptococci were 19.8, 9.9, 29.2, 14.0 and 18.2%, respectively. Biochemical and serological studies showed that 10.5% of total Escherichia coli were enteropathogenic E. coli. Of sixty strains tested against six antibacterial drugs, 57% were resistant to one or more of the drugs. The incidence of resistance to ampicillin, chloramphenicol, sulphonamide, streptomycin, tetracyline and gentamycin was 40.0, 25.0, 43.3, 18.3, 20.0 and 8.3%, respectively.     

Twin studies demonstrate a host cell genetic effect on productive human immunodeficiency virus infection of human monocytes and macrophages in vitro.

Biological and genetic variability is a prominent feature of human immunodeficiency virus (HIV) strains, especially in tropism, syncytium formation, and replicative capacity. To determine whether there were variable host cell effects on HIV replication in monocytes, three different strains of low-passage-number monocytotropic blood isolates of HIV and the laboratory-adapted strain Ba-L were inoculated into panels of adherent monocytes drawn from 44 different donors, and peak extracellular HIV p24 antigen titers were compared. The clinical HIV strains showed patterns of either moderate or low-level replication in most donor monocytes (20 to 4,000 pg/ml). However, within this range there was marked variation in peak titers in most donors. HIV type 1 Ba-L replicated in all donor monocytes to much higher levels with less variability (30 to 40 ng/ml). Furthermore, replication of 21 clinical blood-derived strains of HIV in blood monocytes and monocyte-derived macrophages (MDM) from pairs of identical twins and age-matched unrelated donors (URD) of the same sex were compared. In all of the seven pairs of identical twins, the kinetics of replication (measured by extracellular HIV p24 antigen) of panels of four clinical HIV type 1 isolates in monocytes were similar within pairs. However, marked and significant differences in kinetics of HIV production occurred within 10 of the 12 unrelated donor pairs (P = 0.0007). The remaining two URD pairs showed similar kinetic patterns, but only one pair had the same HLA-DR genotype. Similar results were observed with monocytes/MDMs obtained from a second bleed of the same donor. Hence, discordant patterns of HIV replication kinetics between URD monocyte pairs contrasted with concordant patterns in identical twin monocytes. These data strongly suggest a host cell genetic effect on productive viral replication in monocytes and MDMs. So far, no consistent genetic linkage of HIV replication pattern with HLA-DR genotype has been observed.     

An insulin-stimulated kemptide kinase purified from rat liver is deactivated by phosphatase 2A.

Insulin action leads to the rapid stimulation of a cytosolic Kemptide (Leu-Arg-Arg-Ala-Ser-Leu-Gly) kinase (KIK) that has been recently purified to near homogeneity (Klarlund, J. K., Bradford, A. P., Milla, M. G., and Czech, M. P. (1990) J. Biol. Chem. 265, 227-234). To examine its activation mechanism, purified KIK was treated with purified protein phosphatases. The catalytic subunit of phosphatase 2A inhibited the activity of control KIK by about 50% and abolished the 5-fold elevation in KIK activity due to insulin action. The catalytic subunit of phosphatase 1 with equivalent activity based on dephosphorylation of 32P-labeled phosphorylase alpha had no effect on either control or insulin-stimulated KIK activity. The deactivation of insulin-stimulated KIK by phosphatase 2A was time- and concentration-dependent and was blocked by phosphatase inhibitors. The purified native complexes of phosphatase 2A, phosphatase 2A1, and phosphatase 2A2 similarly deactivated KIK. Analyis of control or insulin-stimulated KIK with two antiphosphotyrosine antibodies by immunoblotting and immunoprecipitation failed to detect the presence of phosphotyrosine in the kinase. These results indicate that KIK is activated by phosphorylation as part of a kinase cascade emanating from insulin receptor stimulation.

Nimbolide prevents myocardial damage by regulating cardiac biomarkers,antioxidant level,and apoptosis signaling against doxorubicin‐induced cardiotoxicity in rats

The current work planned to assess the protecting properties of nimbolide against doxorubicin (DOX)‐treated myocardial damage. Myocardial damage was produced with 2.5 mg/kg of DOX given on alternative days (14 days). Thiobarbituric acid reactive substances (TBARS) levels of a lipid peroxidative marker were elevated, whereas reduced body weight, heart weight, blood pressure indices and reduced levels of antioxidants like glutathione‐S‐transferase, superoxide dismutase, catalase, glutathione peroxidase, glutathione, and glutathione reductase were observed in the heart tissue of DOX‐treated animals. DOX‐treated animals showed augmented levels of cardiac markers likes monocyte chemotactic protein‐1, interferon‐gamma, aspartate transferase, creatine kinase, lactate dehydrogenase, creatine kinase‐muscle/brain, heart‐type fatty acid‐binding protein, glycogen phosphorylase isoenzyme BB, transforming growth factor‐β, brain natriuretic peptide, myoglobin, and cTnI in serum. Histopathological assessment confirmed the DOX‐induced cardiotoxicity. Furthermore, DOX‐induced rats showed augmented inflammatory mediators (nuclear factor‐κB [NF‐kB], tumor necrosis factor‐α [TNF‐α], and interleukin‐1β [IL‐1β]) and increased PI3K/Akt signaling proteins (PI3K, p‐Bad/Bad, caspase‐3, and p‐Akt), whereas decreased oxidative markers (HO‐1 and NQO‐1) and p‐PTEN were observed. Nimbolide‐supplemented rats showed reduced activity/levels of cardiac markers and TBARS levels in serum and heart tissue. Levels of enzymatic and nonenzymatic antioxidants were augmented in the heart tissue of nimbolide‐supplemented rats. Nimbolide influence decreased apoptosis, inflammation, and enhanced antioxidant markers through the modulation of p‐Bad/Bad, caspase‐3, PI3K, p‐Akt, TNF‐α, NF‐kB, IL‐1β, HO‐1, NQO‐1, and p‐PTEN markers. The histopathological explanations were observed to be in line with biochemical analysis. Therefore, the finding of current work was that nimbolide has a defensive effect on the myocardium against DOX‐induced cardiac tissue damage.

Spatio-temporal analysis of Egyptian flower mantis Blepharopsis mendica (order: mantodea), with notes of its future status under climate change

Egyptian flower mantis Blepharopsis mendica (Order: Mantodea) is a widespread mantis species throughout the southwest Palearctic region. The ecological and geographical distribution of such interesting species is rarely known. So, through this work, habitat suitability models for its distribution through Egyptian territory were created using MaxEnt software from 90 occurrence records. One topographic (altitude) and eleven bioclimatic variables influencing the species distribution were selected to generate the models. The predicted distribution in Egypt was focused on the Delta, South Sinai, the north-eastern part of the country, and some areas in the west including Siwa Oasis. Temporal analysis between the two periods (1900–1961) and (1961–2017) show current reduction of this species distribution through Delta and its surrounding areas, may be due to urbanization. On the other hand, it increases in newly protected areas of South Sinai. Under the future climate change scenario, the MaxEnt model predicted the habitat gains for B. mendica in RCP 2.6 for 2070 and loss of habitat in RCP 8.5 for the same year. Our results can be used as a basis for conserving this species not only in Egypt, but also throughout the whole of its range, also, it show how the using of geo-information could help in studying animal ecology.     

Evolutionary profile of the family Calliphoridae,with notes on the origin of myiasis

The family Calliphoridae is a group of heterogenous calyptrate flies with a worldwide distribution including species of ecological, veterinary, medical, and forensic importance. Notorious for their parasitic habits, the larvae of many blowflies are characterised – like some other dipteran larvae – by their ability to develop in animal flesh. When parasitism affects a living host, it is termed “myiasis”. This has led the Calliphoridae to be considered as a pivotal family in its relationship with a man. Nevertheless, even after more than 50 years of research, the phylogenetic relationships among calliphorid subfamilies together with the evolutionary origin of myiasis remain unclear. In order to elucidate these problems, we constructed three phylogenetic trees by using nucleotide sequence data from cytochrome oxidase subunit one (COI), representing a mitochondrial conservative gene, and nuclear 28S subunit of ribosomal RNA gene (28S rRNA) in order to interpret the evolutionary profile of myiasis in the family Calliphoridae. The sequenced data represented species associated with ectoparasitic life-styles, either saprophagy or facultative and obligate parasitism. A total number of 50 accessions were collected for 28S rRNA, 56 for COI, and 38 for combined sequences phylogeny. Molecular Evolutionary Genetics Analysis (MEGA) software was used to align 2197 nucleotide positions of 28S rRNA and 1500 nucleotide positions of COI with a gap opening penalties and gap extension penalties equalling 20 and 0.1 respectively. The results reveal the non-monophyly of the family Calliphoridae despite the stable monophyletic status of the Chrysomyinae, Luciliinae, and Auchmeromyiinae. Also, our findings recommend ranking the Toxotarsinae as a separate family. Furthermore, comparative analysis of the phylogenetic trees shows that the habit of obligatory myiasis originated independently more than five times. This strengthens our hypothesis that the origin of eating fresh meat is a case of convergent evolution that has taken place after speciation events millions of years ago. Finally, estimating the divergence dates between lineages from molecular sequences provides a better chance of understanding their evolutionary biology.
