Initially studied and developed by students in universities, the very small pico satellites （with a mass lower than 1 kg） are more and more considered for science applications. In particular, there are plans to use them in constellations of small spacecraft for remote sensing of various regions of the magnetosphere. They require a payload with specific size, weight and power consumption. In order to respond to this demand, new instruments have to be developed. Those instruments should exhibit at least the same performances as those used in larger satellites while fulfilling the specific requirements imposed by the satellites size. For this reason, the authors currently develop a xylophone bar magnetometer （XBM） based on micro-electromechanical systems （MEMS） with integrated detector electronics. The principle of this magnetometer is based on a classical resonating xylophone bar. A sinnsoidal current oscillating at the fundamental bending resonant frequency of the bar is applied through the device, and when an external magnetic field is present, the resulting Lorentz force yields the bar to vibrate at its fundamental mode with a displacement directly proportional to the amplitude in one direction of the ambient magnetic field. When designing a MEMS XBM, the detection method is a crucial aspect. The measurement method largely influences the geometry of the magnetometer as well as the manufacturing technology. Due to the constraints in terms of size, weight and power consumption, the two most promising measurement methods are capacitive and piezoelectric ones. Several designs including these measurement techniques are presented and simulated under realistic conditions. First, designs including lateral electrodes for capacitive measurement are tackled based on Silicon-On-Insulator （SOI） process. For the piezoelectric detection, a new configuration based on Lead Zirconate Titanate （PZT）/Pt structure is introduced and leads to much better sensitivity than the traditional

AIM To investigate the independent effects of 6-mo of dietary energy restriction or exercise training on wholebody and hepatic fat oxidation of patients with nonalcoholic fatty liver disease(NAFLD).METHODS Participants were randomised into either circuit exercise training(EX;n = 13;3 h/wk without changes in dietary habits),or dietary energy restriction(ER) without changes in structured physical activity(ER;n = 8).Respiratory quotient(RQ) and whole-body fat oxidation rates(Fatox) were determined by indirect calorimetry under basal,insulin-stimulated and exercise *** of disease and steatosis was determined by liver histology;hepatic Fatox was estimated from plasma β-hydroxybutyrate ***;cardiorespiratory fitness was expressed as VO2 ***-case analysis was performed(EX:n = 10;ER:n = 6).RESULTS Hepatic steatosis and NAFLD activity score decreased with ER but not with EX.β-hydroxybutyrate concentrations increased significantly in response to ER(0.08 ± 0.02 mmol/L vs 0.12 ± 0.04 mmol/L,P = 0.03) but remained unchanged in response to EX(0.10 ± 0.03 mmol/L vs 0.11 ± 0.07 mmol/L,P = 0.39).Basal RQ decreased(P = 0.05) in *** EX,while this change was not significant after ER(P = 0.38).VO_(2peak)(P 0.05).The increase in β-hydroxybutyrate concentrations was correlated with the reduction in hepatic steatosis(r =-0.56,P = 0.04).CONCLUSION ER and EX lead to specific benefits on fat metabolism of patients with *** hepatic Fat_(ox) in response to ER could be one mechanism through which the ER group achieved reduction in steatosis.

Evolutionary diversity can be driven by the interaction of plants with different environments. Molecular bases involved in ecological adaptations to abiotic constraints can be explored using genomic tools. Legumes are major crops worldwide and soil salinity is a main stress affecting yield in these plants. We analyzed in the Medicago truncatula legume the root transcriptome of two genotypes having contrasting responses to salt stress： TN1.11, sampled in a salty Tunisian soil, and the reference Jemalong A17 genotype. TN1.11 plants show increased root growth under salt stress as well as a differential accumulation of sodium ions when compared to A17. Transcriptomic analysis revealed specific gene clusters preferentially regulated by salt in root apices of TN1.11, notably those related to the auxin pathway and to changes in histone variant isoforms. Many genes encoding transcription factors （TFs） were also differentially regulated between the two genotypes in response to salt. Among those selected for functional studies, overexpression in roots of the A17 ge- notype of the bHLH-type TF most differentially regulated between genotypes improved significantly root growth under salt stress. Despite the global complexity of the differential transcriptional responses, we propose that an increase in this bHLH TF expression may be linked to the adaptation of M. truncatula to saline soil environments.

Nutritional Quality of Meat from Cattle Breed in Livestock Production Area of Cameroon

Open Journal of Animal Sciences 2022年第3期12卷 467-483页

作者： Ronald Vougat Ngom Vincent de Paul Ndzana Dangwang Bohounbele veronique Houli Boubakary Oumara Andre Zoli Pagnah Department of Animal Production School of Veterinary Medicine and Sciences University of Ngaound&#233r&#233 Ngaound&#233r&#233 Cameroon Comité International de la Croix-Rouge Antenne de Maroua Maroua Cameroun Far North Regional Delegation of Livestock Fisheries and Animal Industries Maroua Cameroon Centre d’Appui à la recherche et au Pastoralisme Maroua Cameroun

In Cameroon, foods of animal origin are an important part of the population’s diet. To improve meat consumption and assure its safety, the Government plan a project for the industrialization of cattle and pig industries by building a slaughter chain, cold stores and acquiring of vehicles and trucks for the transport of meat from livestock production areas to other parts of the country. Maroua city in the Far North Region has been selected to host a modern mixed slaughterhouse with a slaughter capacity of 150 cattle/day. To assess the impact of this project, it is important to define a baseline in term of beef quality prior to the implementation of such a project. Therefore, this study aimed to evaluate the nutritional quality of beef in Maroua (as a reference for livestock production area in Cameroon) in relation to demographics of cattle (production system, type of production, age, breed, body condition score [BCS], and sex). In 2014, data on demographics of 202 cattle, randomly selected in the traditional slaughterhouses of Maroua were collected. At the end of the slaughter chain, approximately 250 g of thigh were sampled from each animal selected. However, 76 randomly selected thigh meat samples were suggested for chemical composition analysis by using standard methods. Results revealed that dry matter (26.30% - 29.88% of fresh matter), ash (0.92% - 1.09% of fresh matter), total fat (10.12 - 19.58 of fresh matter) and protein (8.60% - 27.59% of fresh matter) content of beef were between the acceptable ranges for table meats. The total protein content found was affected by the BCS, the age at slaughter, the breed and the sex of the animal. In addition, as expected, the total fat content increased with the BCS and varied with the age at slaughter and the type of production. Since the fat content decreased with age and varied with the type of production, it would be interesting for further study, to determine the fatty acids profile of meat from fattening cattle of
