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.     

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.

Problems concerning the operation of high productivity biomass fermentations using volatile liquid hydrocarbon feedstocks

The possibilities of using liquefied petroleum gas (LPG) heavy ends, predominantly volatile liquid n-alkanes (a location-specific hydrocarbon feedstock) for single-cell protein (SCP) production are examined against criteria established to define potentially attractive SCP production processes. The factors discussed include the use of the heat of vaporization for fermentor cooling, the efficiency of conversion of nalkane vapors, problems of maintaining constant composition substrates when feeding volatile liquid n-alkane vapors to laboratory fermentors, the possible solvent effect of liquid n-alkanes, and the possibilities of competitive inhibition. The study confirms that mixed volatile n-alkane feedstocks will introduce major physical and biological problems for both product and process research and development. Even when the technical problems are solved, the economic question of whether a direct production route using the feedstock as the fermentation substrate or an indirect route involving the conversion of the feedstock, by chemical means, into methanol, which can then be used as the fermentation substrate, needs careful examination.     

Fourfold paralogy regions on human HOX-bearing chromosomes: Role of ancient segmental duplications in the evolution of vertebrate genome

BackgroundSusumu Ohno’s idea that modern vertebrates are degenerate polyploids (concept referred as 2R hypothesis) has been the subject of intense debate for past four decades. It was proposed that intra-genomic synteny regions (paralogons) in human genome are remains of ancient polyploidization events that occurred early in the vertebrate history. The quadruplicated paralogon centered on human HOX clusters is taken as evidence that human HOX-bearing chromosomes were structured by two rounds of whole genome duplication (WGD) events.ResultsEvolutionary history of human HOX-bearing chromosomes (chromosomes 2/7/12/17) was evaluated by the phylogenetic analysis of multigene families with triplicated or quadruplicated distribution on these chromosomes. Topology comparison approach categorized the members of 44 families into four distinct co-duplicated groups. Distinct gene families belonging to a particular co-duplicated group, exhibit similar evolutionary history and hence have duplicated simultaneously, whereas genes of two distinct co-duplicated groups do not share their evolutionary history and have not duplicated in concert with each other.ConclusionThe recovery of co-duplicated groups suggests that “ancient segmental duplications and rearrangements” is the most rational model of evolutionary events that have generated the triplicated and quadruplicated paralogy regions seen on the human HOX-bearing chromosomes.     

A histological,immunohistochemical and biochemical study of the effects of pomegranate peel extracts on gibberellic acid induced oxidative stress in adult rat testes

ABSTRACT

Gibberellins are commonly used plant growth regulators that exhibit deleterious effects on various animal tissues. We investigated the histological, immunohistochemical and biochemical effects of gibberellic acid (GA3) on rat testes as well as the possible protective role of pomegranate peel extract (PPE). We used 28 adult male rats divided into control, PPE treated, GS3 treated and GA3 + PPE treated groups. Testis specimens were analyzed for superoxide dismutase (SOD) and catalase (CAT) activity, and examined histologically. We also investigated the androgen receptor using immunohistochemistry. The GA3 treated group exhibited significantly decreased SOD and CAT levels and area percent of androgen receptor. Seminiferous tubules (ST) were widely separated and the germinal epithelium was separated from the basement membrane in some tubules. Areas of vacuolation, degenerated germ cells with pyknotic nuclei and large multinucleated cells were observed. Ultrastructurally, primary spermatocytes exhibited vacuolated cytoplasm, degenerated mitochondria and hyperchromatic nuclei. Degenerated early spermatids with a ruptured or hyperchromatic nucleus were found. Spermatozoa exhibited abnormalities of the head and tail. The cytoplasm of Sertoli and Leydig cells exhibited dilated smooth endoplasmic reticulum. A significant improvement of the biochemical, histological and immunohistochemical alterations was observed in the GA3 + PPE treated group compared to the GA3 treated group.     

Guillain-Barré syndrome as a cause of acute flaccid paralysis in Iraqi children: a result of 15 years of nation-wide study

Background

Guillain-Barré syndrome (GBS) is the most common cause of acute flaccid paralysis (AFP) in the post-poliomyelitis eradication era. This is the first study done to identify the epidemiology, clinical features, and outcome of GBS in Iraqi children over 15 years.

Methods

The surveillance database about AFP cases?<?15 years reported during January 1997-December 2011 was used.

Results

GBS represented 52.5% of AFP cases, with an incidence of 1.33 case/100,000 population?<?15 years/year. There was a higher incidence in the Southern provinces, age group 1–4 years, males, and outside the capital city of province, with no significant seasonal variations (p?=?.22). Survival probability after the 1 year of onset for those with respiratory muscle involvement was .76 (95% CI: .60-.86), versus .97 (95% Cl: .96-.98) for those who did not develop it (p?<?.001); and .97 (95% CI: .96-.98) for those living inside the capital city, versus .94 (.93-.95) for those living outside (p?=?.001). Cumulative incidence of residual paralysis for patients living inside the capital city was .21 (95% CI: .18-.24), versus .27 (95% CI: .25-.29) for those living outside (p?<?.001).

Conclusions

The incidence, age and gender distribution, and seasonality of GBS among Iraqi children is similar to those reported from other previous studies. It is the most important cause of AFP, especially in those between the age of 1 to 4 years living in rural areas.

     

Improved Chiral SFC Screening for Analytical Method Development

In this study we describe the evaluation of a recently developed supercritical fluid chromatography (SFC) instrument for automated chiral SFC method development. The greatly improved gradient dwell volume and liquid flow control of the new instrument in combination with the use of shorter columns containing smaller stationary phase particles affords chiral SFC method development that is faster and more universal than previous systems.
