MORPHOMETRIC AND MOLECULAR STUDIES OF THE CORRELATION BETWEEN CHRONIC MASTITIS AND INFERTILITY IN DAIRY CATTLE
No full textDairy cow fertility has declined over the past decades even within the recent developments in functional genomics and genetic selections. There is overwhelming evidence that increasing genetic merit for milk yield considerably reduces fertility and the strength of negative associations between yield and fertility is obviously towards a rising trend. The deterioration of resistance or increased susceptibility to mastitis as well as reduced fertility in today’s cow, are the examples of undesirable side-effects of the high emphasis on production traits in selection decision. Although, recent studies suggested an association between reproductive failure and mastitis in lactating dairy cows, our understanding of how mastitis affects reproduction is still limited. In this context, we investigated the effects of naturally occurring chronic mastitis on fertility particularly at the level of bovine ovarian stroma with matrix fibers, follicular growth factors, characteristic micro-architecture of stromal vasculature, as well as growth and development of follicles by macroscopic and microscopic morphological as well as immuno-detection based molecular analysis of the ovaries collected at slaughter. Ovaries and milk samples were collected from 74 cows at slaughter. Milk samples from each quarter, were analyzed following National Mastitis Council procedures. Following macroscopic assessment, ovaries of 63 animals were scored as healthy, intermediate and pathological. Based on the presence of major pathogens and somatic cell count results, animals were sorted in 9 groups but only the two extremes were considered for further analysis: uninfected (n = 8) and affected by chronic mastitis (n = 9). Primordial, primary and secondary follicles were counted and scored on similar surface area of ovary sections for each animal (mean ± SD= 5.65 ± 0.25 cm2). They were analyzed with Fisher’s exact test and the association between health status and follicle number was estimated by odds ratios ± confidence limits. Stromal cells with matrix collagen fibres were visualized with Masson trichrome staining. Vasculature area in the ovarian cortex of healthy and mastitic animals was identified using Bandeiraea simplicifolia-I (BSL-I) Lectin. Results were quantified with the dedicated software MacBiophotonics image J, NIH, USA and subsequently analyzed with t-test for statistical significance. Follicles were further characterized by immunostaining with a GDF-9 specific antibody. GDF positive follicular area was measured as well as using a relative scale its fluorescence was semi-quantified. Our results indicate no noticeable macroscopic alteration amongst various macroscopic parameters. Similarly, no (P>0.05) difference was observed between the numbers of primordial and primary follicles in healthy and affected animals. In contrast, the number of secondary follicles was significantly lower in sick animals (Odds ratio 10.50*; p<0.05), indicating a 10 times higher risk for a mastitis animal to have less than 2 secondary follicles per square centimeter. In the healthy and mastitic animals the stromal collagen were (1.61±0.90% vs. 6.046±1.85% P<0.001), indicating mastitis is linked with stromal alterations. Ovarian stromal vasculature represented the cortical area of 6.38±0.66 % in healthy vs. 4.24±0.37%; (P<0.001) in affected cows. Likewise, reduced GDF-9 expressed cortical area, healthy vs. sick (1.97±0.83% vs. 1.04±0.11%; P<0.05), with less immuno-fluorescence was observed in mastitic animals. Our results show that chronic mastitis is associated with considerable alterations in follicle growth and differentiation with a decreased ability of primary follicles to develop into the secondary state in affected animals. This is accompanied by a significant increase of stromal collagen with reduced vasculature and the down regulation of the follicle differentiation factor GDF-9. All together, these findings substantiate the hypothesis that mastitis can reduce fertility by exerting a negative effect on ovarian function

Political regime structures macroeconomic policy outcomes and instruments use in the Mena region
No full textThis study investigates the possible occurrences of patterns in macroeconomic
policy targeting and instruments use in some Middle East and North Africa(MENA)
countries where political regimes generally differ across countries and through time.
Some of these patterns are held to correspond to those stipulated by the Partisan Theory
and its Rational version for advanced democracies after due allowance is made for the
nature of government and modes of regime transfer. In particular, we trace the
differential evidence of partisan effects on output growth and inflation; and on rhythm
in the use of instruments of finance through seigniorage and inflation taxation. Patterns
on the mode of use of policy instruments through reliance on monetary policy surprises
are also investigated. Effects of various political structure attributes on the policy
outcome variables and instruments use are also considered in a latter part of the study.
Empirical results obtained generally point to the possible presence of eco-political
patterns similar in principle to those operable in the case of Developed Countries but
with some distinct differences in nature and rhythmEconomic Research Forum under research grant number ERF99-SA-4001. Department of Economics, King Saud University, RiyadhCorresponding Author:

Partisan theory and macroeconomic policy under unscheduled regime transfers, A case study of an LDC
No full textIn this paper we investigate the possible occurrences of patterns in macroeconomic policy
targeting and instruments use in some Less Developed Countries where unscheduled regime transfers
may occur. The patterns are held to correspond to those stipulated by Hibbs in his Partisan Theory for
advanced democracies after due allowance is made for the nature of government and modes of regime
transfer. The investigation is undertaken with special reference to the Sudan, a country which has
witnessed dramatic political changes that assumed the forms of eight alternating regimes in the shape
of civilian democracies and military dictatorships since its independence in 1956. In particular, we
trace the evidence on quasi-political business cycles in output growth and inflation; and on quasipolitical
budget cycles in deficits and instruments of finance. Patterns on the form of use of policy
instruments through reliance on monetary policy surprises are also investigated. Empirical results
obtained generally point to the possible presence of eco-political patterns similar in principle to those
operable in the case of Developed Countries but with some distinct differences in nature and rhythm.Corresponding Author:

Current concepts on oxidative/carbonyl stress, inflammation and epigenetics in pathogenesis of chronic obstructive pulmonary disease
No full textChronic obstructive pulmonary disease (COPD) is a global health problem. The current therapies for COPD are poorly effective and the mainstays of pharmacotherapy are bronchodilators. A better understanding of the pathobiology of COPD is critical for the development of novel therapies. In the present review, we have discussed the roles of oxidative/aldehyde stress, inflammation/immunity, and chromatin remodeling in the pathogenesis of COPD. An imbalance of oxidants/antioxidants caused by cigarette smoke and other pollutants/biomass fuels plays an important role in the pathogenesis of COPD by regulating redox-sensitive transcription factors (e.g., NF-κB), autophagy and unfolded protein response leading to chronic lung inflammatory response. Cigarette smoke also activates canonical/alternative NF-κB pathways and their upstream kinases leading to sustained inflammatory response in lungs. Recently, epigenetic regulation has been shown to be critical for the development of COPD because the expression/activity of enzymes that regulate these epigenetic modifications have been reported to be abnormal in airways of COPD patients. Hence, the significant advances made in understanding the pathophysiology of COPD as described herein will identify novel therapeutic targets for intervention in COPD
Balancing contractual and relational approaches for PPP success and sustainability
No full textUseful synergies are targeted by proposing a convergence of hitherto parallel international endeavours towards: (1) developing better and sustainable relationships for more productive construction project teams, in general; and (2) optimising the necessarily long term contractual arrangements of PPPs in particular. Examples are drawn from Africa and Latin America to reinforce reported PPP experiences from other regions, in building up a case for injecting ‘relational contracting approaches’ in order to develop more productive and sustainable PPPs. Strong and sustainable relationships are shown to be essential, and complementary to appropriate contractual incentives, that would together empower PPP project teams to focus on developing sustainable infrastructure and ultimately on overall sustainable development. These propositions are merged into a basic model that merits further investigation and development, in order to ensure that planned PPPs benefit the community at large, in respect of both present and future generations
Environmental toxicity, redox signaling and lung inflammation:the role of glutathione
No full textGlutathione (gamma-glutamyl-cysteinyl-glycine, GSH) is the most abundant intracellular antioxidant thiol and is central to redox defense during oxidative stress. GSH metabolism is tightly regulated and has been implicated in redox signaling and also in protection against environmental oxidant-mediated injury. Changes in the ratio of the reduced and disulfide form (GSH/GSSG) can affect signaling pathways that participate in a broad array of physiological responses from cell proliferation, autophagy and apoptosis to gene expression that involve H(2)O(2) as a second messenger. Oxidative stress due to oxidant/antioxidant imbalance and also due to environmental oxidants is an important component during inflammation and respiratory diseases such as chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, acute respiratory distress syndrome, and asthma. It is known to activate multiple stress kinase pathways and redox-sensitive transcription factors such as Nrf2, NF-kappaB and AP-1, which differentially regulate the genes for pro-inflammatory cytokines as well as the protective antioxidant genes. Understanding the regulatory mechanisms for the induction of antioxidants, such as GSH, versus pro-inflammatory mediators at sites of oxidant-directed injuries may allow for the development of novel therapies which will allow pharmacological manipulation of GSH synthesis during inflammation and oxidative injury. This article features the current knowledge about the role of GSH in redox signaling, GSH biosynthesis and particularly the regulation of transcription factor Nrf2 by GSH and downstream signaling during oxidative stress and inflammation in various pulmonary diseases. We also discussed the current therapeutic clinical trials using GSH and other thiol compounds, such as N-acetyl-l-cysteine, fudosteine, carbocysteine, erdosteine in environment-induced airways disease
Acute phase protein response in Alpine ibex with sarcoptic mange
No full textThe acute phase proteins (APP) are a group of serum proteins that change their concentration in animals following external or internal challenges, such as infection, inflammation or stress. The concentrations of four APPs, including serum amyloid A (SAA), haptoglobin (Hp), α1-acid glycoprotein (AGP) and ceruloplasmin (Cp) were determined in serum collected from healthy Alpine ibexes (Capra ibex) and ibexes with Sarcoptes scabiei mange. Primary structures of all four APPs were determined by cDNA sequencing. The concentrations of all four APPs were higher in serum of animals with clinical signs of sarcoptic mange when compared to healthy animals. Two of the APPs, including SAA and AGP, acted as major APPs, since their serum concentrations were increased more than 10-folds when compared to healthy animals (P < 0.001). The other two APPs, including Hp and Cp, acted as minor acute phase proteins, as their concentrations were increased from two to five folds (P < 0.001).
These findings provide a remarkable potential as diagnostic markers for the early detection of sarcoptic mange in free ranging animals
