Aim: Over the last 15 years, hyaluronic acid (HA) fillers have become the most popular injectable biomaterial for soft tissue correction. With the increasing number of available HA fillers and the multiplication of facial treatments all over the world, there has been a need from physicians to better understand the HA fillers science. There is especially a growing interest in the science-based evaluation of rheological characteristics which represents an essential tool to guide physicians in the selection of the most appropriate HA fillers, administration techniques and depths of injection for their clinical applications. Methods: Four key rheological parameters (viscosity η, elasticity G', normal force FN and elasticity E') are measured and discussed on five HA fillers. Results: These four key rheological parameters are demonstrated to play a pivotal role, in combination with the cohesivity, for better predicting the clinical behavior of HA fillers at different stages of their lifetime. Conclusion: This article discusses the importance of four key rheological parameters during the main steps of the clinical HA fillers' lifetime, from the product injection to the loss of clinical effects. A better knowledge of these HA fillers' rheological parameters can help the physicians to optimize their aesthetic outcomes, safety and patient satisfaction.

Cisplatin is one of the most broadly used chemotherapeutic agents. Several central nervous system toxicities have been attributed to this agent, among which is a rare clinicoradiological condition referred to as posterior reversible leukoen-cephalopathy syndrome (PRES) or reversible posterior leukoencephalopathy syndrome (RPLS). PRES is characterized by subacute onset of headache, visual disturbances, confusion, seizures and rarely, coma. This usually reversible syn-drome was associated in the past mainly with hypertension. Several reports have associated the syndrome with several immunosuppressive and chemotherapeutic agents suggesting a disruption of the blood brain barrier due to direct damage to the endothelium and vasogenic edema. This syndrome is readily diagnosed with Computed Tomography (CT) or Magnetic resonance imaging (MRI) studies and quick withdrawal of the causative agent in conjunction with supportive care including rapid hypertension control and reduction of elevated intracranial pressure when needed, usually reverse the neurological symptoms with minimal or even no sequela within several days. In this brief report and review of the literature we describe two cases of PRES in two female patients that occurred a few days after receiving Cisplatin-based chemotherapy. We discuss the clinical presentation, diagnosis and treatment of this syndrome by reviewing the literature. The escalating number of clinical reports of PRES merit further studies of the mechanism of toxicity, appropriate treatment and awareness of physicians to this life threatening

分别用前驱体分解法与剥层重堆法制备出二硫化钼纳米球(nano-MoS2)与聚甲醛/二硫化钼夹层化合物(MoS2-IC),再利用制备的nano-MoS2、MoS2-IC与微米二硫化钼(micro-MoS2)作为原料制备出POM/MoS2复合材料。在真空摩擦磨损试验机上考察了复合材料的摩擦学性能,结果表明,POM/nano-MoS2复合材料具有最好的摩擦学性能,POM/MoS2-IC复合材料次之,而POM/micro-MoS2复合材料性能与POM比没有改善;SEM分析显示,POM及其复合材料主要发生的是疲劳磨损,POM/nano-MoS2的疲劳磨损最轻,POM/MoS2-IC疲劳磨损最严重,POM与POM/micro-MoS2除了疲劳磨损外,还存在明显的粘着磨损。

Background: Post-partum haemorrhage is the leading cause of maternal death throughout the world, and anaemia is one of its indirect causes. Anaemia during labour increases the risk of PPH and may lead to maternal mortality even after moderate PPH. Undiagnosed PPH and post-partum anaemia increases the risk of late maternal death in the community. The aim of this study was to assess the prevalence of anaemia on admission for labour, the occult early post-partum haemorrhage and the magnitude of post-partum anaemia in a low resource setting. Methods: This was a longitudinal study. We included pregnant women in labour. Haemoglobin concentration was measured on admission (H0), then 24 hours (H24) and 48 (H48) hours later. The post-partum blood loss was estimated by delta haemoglobin, using the criteria of M. Driessen et al. Results: We recruited 245 pregnant women. The mean age was 27.0 ± 6.0 years. The mean hemoglobin concentration was 11.7 ± 1.9 g/dl, the frequency of anaemia was 30.6% and was related to ethnicity (P = 0.042) gestational age (p < 0.001) marital status (p = 0.014) and the inter pregnancy time space (p = 0.001). Twenty-two-point two percent had post-partum haemorrhage among which 40% were undiagnosed. The mean blood loss was 375 ml and post-partum anaemia rate was 44.5%. Conclusion: Anaemia on admission was related to socio-demographic characteristics. The frequencies of anaemia during labour, missed PPH and undiagnosed post-partum anaemia were high. Haemoglobin concentration on admission for labour and after delivery, reliable method to assess PPH should be mandatory, to better identify per and post-partum anemia, and the management of PPH, in low income environments.

This study was focused to assess major and trace elements in bauxitic duricrusts from Ngaoundal and its surroundings in order to establish their mining interest. To this end, fieldworks, mineralogical and geochemical analyses were carried out. Four facies of duricrust were identified and characterized from the summit to the top of the slope of the Ngaoundal mountain: scoriaceous, pisolitic, nodular and massive. Mineralogical and geochemical analyses performed on 16 samples, revealed a significant concentration of Al2O3 mainly in the scoriaceous facies (over 45% in grade), moderate in Fe2O3 (averaging 23.69%) and SiO2 (averaging 21.7%). Trace elements were generally low, excluding Cr (421 ppm on average), Zr (327 ppm on average and V (213 ppm on average). In addition, the limited quantities of alkalis (Na2O, K2O) and alkaline earths metals (MgO, CaO) coupled with the very high values of Chemical Index of Alteration (CIA) and Mineralogical Index of Alteration (MIA), (more than 99%) attest to the intense weathering of the studied materials. Allitization and monosiallitization constituted the crystallochemical phenomena that have led to the development of bauxitic minerals. More than 90% of gibbsite in scoriaceous facies, 52.21% - 76.01% of kaolinite in pisolitic facies and more than 40% of hematite in nodular facies were quantified. The relationships between the constitutive components indicated their interdependency during the bauxitization phenomenon. The mineralogical and geochemical properties highlighted the mining interest of the studied duricrusts to be valorized.
