Background: Fahr syndrome associates a set of neuropsychiatric manifestations with bilateral calcifications in the basal ganglia and phosphocalcic disorders. Neuromeningeal cryptococcosis can be present in its manifestations, neuropsychic disorders with or without meningeal signs. The objective was to describe a rare association between Fahr syndrome and neuromeningeal cryptococcosis which can be expressed by the same clinical symptomatology in the context of co-infection with the human immunodeficiency virus (HIV) and the hepatitis B virus (HBV). Presentation: A 37-year-old patient without pathological history, who presented behavioral disorders that led to a fight with those around her and a psychiatric consultation. Then, she was hospitalized in the infectious diseases Department upon discovery of her HIV status and viral hepatitis B. She was logorrheic with behavioral disturbances and subsequently presented with tonic-clonic convulsions. Laboratory tests and imaging have concomitantly discovered Fahr syndrome due to pseudohypoparathyroidism and neuromeningeal cryptococcosis. The correct management of these two pathologies enabled stabilization of the patient’s clinical condition with regular monitoring for HIV-HBV coinfection. Conclusion: Farh syndrome and neuromeningeal cryptococcosis are two different entities but sometimes similar symptoms and risk factors. Treatment of metabolic disorders combined with anticryptococcal therapy improved the prognosis.

Background: Acute intestinal invagination or intussusception is the most common abdominal surgical emergency in infants, but it can occur at any age. Performing an ultrasound scan at the slightest clinical suspicion contributes to early diagnosis and therapeutic management. Objective: To show the relevance of ultrasound in the therapeutic management of the child’s intussusception through a correlation between the ultrasound diagnosis and the clinical and/or per operative diagnosis. Patients and Methods: It was a retrospective study of 24 cases from July 2017 to September 2020 (30 months) in the Medical Imaging and Paediatric Surgery departments of Teaching Hospital of Bouaké. We included only patients from 0 to 15 years old who had digestive symptoms, an abdominal ultrasound scan. These patients were eligible for surgery. Data analysis was performed with Epi info 7 software. Results: Median age was 17.2 months [02 - 120]. Male gender predominated (83.3%). Clinico-biological data were dominated by abdominal pain (79.2%), vomiting (75%) and rectorragies (33.3%), with Ombredanne’s triad in 33.3% and hyperleukocytosis (70.8%). Ultrasonography showed invaginated coves (95.8%) sitting in the right angl iliac fossa, peri-umbilical and right flank in 73.9%. Cockade image coupled with the sandwich image accounted for 95.6%. Superficial adenopathies (45.8%) and peri-lesional fluid effusion (20.8%) were associated with it. An occlusive syndrome complicating intussusception was observed in 41.67% associated with intra-peritoneal effusion of fluid (25%). There was a significant diagnostic agreement between the clinic, ultrasound and surgery according to the Fisher’s exact test (p = 0.002). That between ultrasound and surgery was calculated at 95.4%. Conclusion: This study allowed us to show a good clinical-echo-surgical concordance. Ultrasound is therefore an undeniable diagnostic, prognostic an

阳离子无序正极材料是近年来新发现的一类具有极高比容量的锂离子电池正极材料[1]。其结构为立方岩盐相,4a位的金属阳离子占位随机混排。充电过程中该类材料除了发生常规的过渡金属氧化外,在充电后期还会发生阴离子氧化。目前对于锂电正极材料的阴离子氧化还原有两种主流理论:一是形成O2n-二聚体[2];二是氧的非键2p轨道上形成定域电子空穴[3]。理解阴离子氧化还原机理有助于提高此类材料的电化学性能。NMR谱学能够给出不同原子核的局域环境信息,十分适合于缺少长程有序结构的阳离子无序正极材料的研究。EPR谱学可给出未成对电子的信息,适合于研究各种阳/阴离子的氧化还原。

Introduction: The risk of transmission of pathogens such as hepatitis B virus threatens the safety of transfused patients especially in high endemic areas. The aim of this study was to determine the incidence and factors associated with hepatitis B virus surface antigen (HBsAg) seroconversion in blood donors at the Regional Blood Transfusion Centre of Ouagadougou. Methods: A retrospective cohort study of voluntary non-remunerated blood donors (VNRBD), was conducted from 2008 to 2017. Data on HBsAg seroconversion were collected. The Kaplan-Meier method and the Log-Rank test were used to estimate the survival curves. Cox’s regression identified the factors associated with this seroconversion. Results: Of 23,494 donors, 559 had HBsAg seroconversion. The number of donor years was 58,637.50 and the HBV incidence rate was 9.53 per 1000 donor years. The median seroconversion time was 75.73 months with extremes of 2.7 months and 107.12 months. The risk of seroconversion was 1.30 times higher among donors aged 21 to 24 years old (p = 0.007) and 2.49 times higher among those over 24 years old (p Conclusion: The incidence of HBsAg remains high among blood donors, which could have a negative impact on transfusion safety. The age of the blood donor was significantly associated to AgHBs seroconversion.

Fish is rich in essential nutrients but can remain a potential source of food poisoning. A study was, therefore, carried out with the general objective of highlighting the probable biological and chemical dangers associated with the consumption of fish and freshwater fruits from the Guéssabo river. The present study was conducted on 50 carp fish, 50 mackerel fish, 50 frogs and 50 mollusks caught in the Guéssabo River. Microorganisms were enumerated by conventional tests and heavy metals were investigated by Inductively Coupled Plasma Optical Emission Spectrometry. The enumeration showed high levels of thermotolerant Coliforms (2.5 × 104), Enterobacteriaceae (3.4 × 104), S. aureus (2.3 × 103) and Yeast/Molds (2.1 × 104), in all samples the standards were not in conformity with the required standards. High levels of Al (7230 μg/kg) and Cd (21.57 μg/kg) were observed in carp fish and these values are above the standard. In conclusion, the fish caught in the Guéssabo River could be a health risk factor for the consumer.

The Oak Ridge National Laboratory (ORNL) is the largest and most diverse energy, research, and development institution within the Department of Energy (DOE) system in the United States. As such, the site endures constant land development that creates rigorous growing conditions for urban vegetation. Natural resource managers at ORNL recognize that trees are an integral component of the landscape and are interested in characterizing the urban forest and their associated ecosystem services benefits. We evaluated the urban forest structure, quantified ecosystem services and benefits, and estimated economic value of resources using i-Tree Eco at ORNL. While this assessment captured over 1100 landscape trees, the ORNL Natural Resources Management for landscape vegetation can be expanded to include unmanaged landscapes, e.g. riparian areas, greenspace, and other vegetative attributes to increase ecosystem services benefits. Assigning a monetary value to urban forest benefits help to inform decisions about urban forest management, ideally on cost-benefit analysis.

SiC/SiO2复合涂层是显著改善先进高温气冷用石墨抗氧化性能的一个理想涂层体系，但目前其优化的化学气相沉积工艺还未见诸报道。本研究利用HSC-CHEMISTRY 4.1分析了化学气相沉积工艺对制备的SiC/SiO2复合涂层的影响。分析结果表明：载气中加入足够的氢气对制备不含杂质的SiC/SiO2复合涂层很有必要；合适的沉积温度为1100-1200℃；最佳反应物浓度为：SiCl4摩尔分数为1%-2%，沉积SiC涂层时CH4与SiCl4的摩尔比为1，沉积SiO2涂层时水蒸气与SiCl4摩尔比为2，通过逐渐改变CVD气氛中的水蒸气与CH4的比例来沉积SiC/SiO2梯度过渡层。
