The effect of substituting corn with sorghum grains with low tannin content (LTC) on broilers performances was investigated in a 6-week feeding trial. Seven hundred fifty 1-day old chicks and not sexed Coob 500 were used in this test. These animals were separated into five groups with three replicates of 50 birds for each one. A control diet with 50% of corn was used in the control group. Three other diets where corn was substituted by conventional sorghum in 1/3, 2/3 and 3/3 were given respectively to the G1/3, G2/3 and G3/3 groups. The GLTC groups received diets with total substitution of maize by sorghum with LTC. No significant difference was shown for the body weight between the control and the GLTC groups (respectively 1303 and 1418 g). But the use of conventional sorghum decreases significantly the broilers weight live (p>0.05) with the lower weight performances (1128 to 1225 g). Mortalities were similar for the different groups. It’s always results to climatic environment which was identical for the different group. No difference has been observed for the carcass dressing percentage (68 to 76%). For the nutrients digestibility, except the fat matter which was difference and higher (more than 92%), dry matter, ash and then metabolizable energy were similar (p>0.05) in the starting and growing diets.

Intra-articular (IA) corticosteroids (CS) have been used in the treatment of osteoarthritis for many years, although their effects on articular cartilage are not fully understood. To identify whether previous animal studies have provided enough evidence about the effects of CS, we undertook a systematic review that identified 35 relevant in vivo animal experimental studies between 1965 and 2014 assessing the effects of CS on either normal cartilage, or in either induced osteoarthritis (OA) or synovitis. The quality of the methodology was assessed. Deleterious effects, both structural and biochemical, have mainly been reported in rabbits and are associated with frequent administration of CS, sometimes at high dose and with systemic side effects. In dogs, four identified studies concluded that there were beneficial effects with methylprednisolone acetate (MPA) and triamcinolone hexacetonide therapy. In horses, MPA was mostly deleterious, while triamcinolone acetonide had positive effects in one study highly rated at quality assessment. However, many methodological weaknesses have been identified, such as the lack of pharmacokinetic and pharmocodynamics data and the large variation in doses between studies, the limited selection criteria at baseline, the absence of blinding, and the lack of statistics or appropriate controls for testing the effects of the vehicle of the drug. Those methodological weaknesses weaken the conclusions of numerous studies that assess beneficial or deleterious effects of CS on articular cartilage. Animal studies have not yet provided definitive data, and further research is required into the role of CS in articular pathobiology. [less ▲]

The effect of bovine colostrum, including its thermally labile compounds, on the survival and growth performance of local breed piglets reared by their mother, in Benin, was evaluated over a 49-day trial. Three groups of 16 piglets, stemming from two primiparous sows belonging to a unique traditional farm, were respectively fed for the first 48 h of life with either bovine colostrum heated to 85 °C for 30 min, or thawed bovine colostrum, or colostrum from the mother. Thereafter, the animals that received bovine colostrum turned back to their mother. At day 21, almost all piglets from the group that received heated colostrum died. The highest total weight gain was obtained in the group that received thawed bovine colostrum (P ˂ 0.01), followed by the group left with the mother. Corresponding average daily gains (ADGs) were 56, 34 and 2 g/day, respectively (P ˂ 0.05). At the end of the trial, the treatment effect was highly significant on the survival of piglets (100% in the thawed colostrum group vs. 00 and 50%, respectively, in the heated colostrum group and in the group left with the mother). At day 49, numerically higher weight and ADGs were obtained in the group that received thawed cow colostrum. Thawed bovine colostrum improved the growth performance and piglet survival in the local pig breed in Benin, probably owing to thermally labile components. Bovine colostrum may be used in our farms in order to reduce pre-weaning mortality, improve the profitability of livestock farmers, and ensure survival of traditional farms. The use of bovine colostrum on farms could be facilitated by collaboration between pig farmers and bovine farmers. It could also be facilitated by the creation of a colostrum bank. [less ▲]

Numerous interpretations regarding the content, the form, and the rationale for CSR co-exist despite the publication of international codes of conduct such as the U.N. Global Compact. The variety in perceptions of CSR can be explained by a number of factors: individual characteristics such as gender, age, and personal values; organisational characteristics such as firm size and organisational culture; and environmental factors such as industry and national institutions. The latter factor lies at the core of this thesis, which attempts to evaluate the influence of culture, i.e. informal institution, on the perception of CSR by using Hofstede’s cultural values framework. Annual reports and CSR reports and corporate web pages of thirty large corporations issued from two industries and three countries are systematically reviewed. Besides an important industry effect, several relationships between culture and the perception of CSR can be observed, though their direction is sometimes contrary to expectations or unclear. Summing up, firms perceive they need a broader commitment to CSR to acquire their social license to operate in stronger uncertainty avoidance, less masculine and less individualistic countries. Lower individualism, lower masculinity, and higher uncertainty avoidance indexes are associated with a perception of CSR as a strategy resulting in net benefits. Overall, this thesis contributes to the argument against the universality of CSR in the academic debate and shows the necessity to consider culture and industry in analysing CSR. It also insists on the importance of industrial recipes and isomorphism in integrating CSR in businesses’ corporate strategy. [less ▲]

Stainless steel bipolar plates can be excellent alternative to graphite bipolar plates since they display better mechanical properties and the manufacturing procedure is easier and cheaper. However, they are chemically instable in the corrosive environment of PEMFCs, and a thin oxide layer is developed on the plate’s surface. This layer causes a significant increase in the interfacial contact resistance (ICR) between the plates and gas diffusion layers. In an effort to characterize various stainless steel samples, before and after their exposure to the corrosive environment of a PEMFC, the interfacial contact resistance (ICR) between the plates and a commercial gas diffusion layer (GDL) was studied as a function of the pressure applied on the assembly. The ICR was studied in the range of 0-500 N/cm2 of pressure applied to the assembly; the ICR value was determined by means of galvanostatic potentiometry, where a constant current is applied to the assembly and the average value of the potential over time is recorded. The ICR is then calculated, after appropriate simplifications, as: ICR = Rtot = Iapplied / Vmonitored (1) It was observed that, besides the expected exponential reduction of ICR versus pressure, the value of the current applied to the assembly impacted greatly the obtained values for the ICR, irrespective of the applied pressure. This indicates that the observed phenomenon is not caused by any morphological changes on the interface. A possible explanation is that, at higher currents, the temperature increases locally due to ohmic heating, inducing thus changes in the GDL’s resistivity. [less ▲]

Artemisinin is extracted from the Asian plant Artemisia annua L. It has been proven to be, with its derivatives, the molecules that have shown so far the most powerful activity on malaria, even in its complicated forms and resistance cases. To resolve the problem of low aqueous solubility of this molecule, the use of cyclodextrins (CDs) was envisaged and gave good results in this topic. However, the impact on its stability and in vitro dissolution, important parameters for drug formulation and evaluation, was not evaluated. In this study, stability in accelerated degradation conditions and in vitro dissolution analysis of artemisinin were performed in comparison with complexes of artemisinin and cyclodextrins. The finding of this work allowed us to suggest that CDs improve the stability of artemisinin, especially when it's in aqueous solution. We also demonstrated the beneficial impact of cyclodextrins on the in vitro dissolution of artmisinin from capsules prepared with rough extracts of A. annua. [less ▲]

PURPOSE: Ro 28-2653 (RO) is a synthetic inhibitor of matrix metalloproteinases (MMPs), which is potentially effective against bronchial remodeling. Given that this molecule has very poor aqueous solubility, different cyclodextrins (CDs) have been tested to increase its solubility. The aim of this study was to prepare and to characterize inclusion complexes between RO and CDs, in order to develop nebulizable solutions. METHODS: The complex formation was investigated by phase solubility studies. (1)H-NMR spectroscopy and molecular modeling studies were carried out to elucidate the structure of the inclusion complex between RO and dimethyl-beta-CD (DIMEB). Nebulizable solutions of RO were developed with CDs and a stability study was performed over 9 months. RESULTS: The phase solubility studies showed that beta-CD and its derivatives form a 1:2 complex with RO, whereas gamma-CD includes RO with a 1:1 stoichiometry and a weak stability constant. T-ROESY spectra showed that DIMEB is able to complex two RO substituents (nitrophenyl and biphenyl groups) with preferential orientations, while molecular modeling demonstrated that the configurations observed with (1)H-NMR are energetically favorable, especially owing to H-bond formation between RO and DIMEB. Two CDs were selected to develop nebulizable solutions of RO and the stability study demonstrated that RO degradation in solution is strongly dependent on the concentration of the 1:2 inclusion complex. CONCLUSIONS: CDs are able to include RO and to improve its aqueous solubility. The beta-CD derivatives can be used to formulate nebulizable solutions of RO, the stability of which depends on the concentration of the 1:2 complex. [less ▲]
