Phase I, Double-Blinded, Placebo-Controlled Dosage-Escalation Study of the Safety and Immunogenicity of EBA-175 RII-NG Malaria Vaccine Administered Intramuscularly

Malaria is an illness caused by a parasite (an animal or plant that lives in or on a host) that enters the human body through the bite of an infected mosquito. The purpose of this study is to find out about the safety of an experimental malaria vaccine and whether the vaccine causes humans to produce antibodies (proteins made by the body's immune system to help control or prevent infection). Four strengths of the vaccine will be tested. The lowest strength of the vaccine will be tested before the next higher strength is tested. Each dosage (shot) of vaccine will be given to 18 people in 4 dosage groups on Day 0, at 1 month and at 6 months. Two people in each dosage group will receive injections of a placebo (contains no medication). Participants will include 80 healthy adults between 18 and 40 years of age. Multiple blood draws will occur over the duration of the study. Participants will be involved in study related procedures for approximately 13 months.

A novel process for extraction of phosphorus from the incinerated sewage sludge ash by modification and leaching

作者: Wang, Jian-guo ; Lu, Zi-can ; Du, Chuan-ming ; Yang, Zhong-hua

Phosphorus (P)-rich incinerated sewage sludge ash (ISSA) presents significant potential for P recovery.However, the chem. and mineralogical complexity of ISSA makes P recovery challenging during leaching due to the dissolution of various impurity elements.To address this, a novel process involving CaO modification, selective leaching, and sequential precipitation was proposed to enable efficient and cost-effective P recovery from ISSA.Initially, ISSA was treated with CaO at high-temperature, which successfully converted all non-apatite phosphorus (Al/Fe-phosphates) into acid-soluble apatite phosphorus (Ca/Mg-phosphates).The selective leaching of P was then optimized by investigating key parameters.Under the optimal conditions (particle size of 0.04-0.05 mm, liquid-to-solid (L/S) ratio of 100:1, pH of 2.0, and temperature of 25 °C), a P dissolution efficiency of 85% was achieved in 40 min, with minimal dissolution of Al, Fe, and Si (less than 5%).To recover phosphate from the leachate, pH was adjusted using NaOH and Ca(OH)₂, resulting in the precipitation of phosphate ions.The co-precipitation of P and Ca was most effective within the pH range of 5.0-8.0, achieving a maximum total P recovery efficiency of 78.06%.The sequential precipitation process, which involved initial pH adjustment with NaOH followed by Ca(OH)₂, minimized alkali consumption and enhanced the purity of phosphate.The precipitate obtained at pH 8.0 was primarily composed of hydroxyapatite (HAP), with a P₂O₅ content of 34.71% and low contents of impurity elements.This study offered a sustainable and efficient pathway for P recovery from ISSA.

Phosphoric Acid Anodizing Effect on Morphology and Corrosion Resistance of Nanostructured Anodic Oxide Layers on 6061 Aluminum Alloy

作者: Lee, Sulki ; Cho, Yi Je

Abstract: Phosphoric acid anodizing (PAA) exhibits a weakness of low corrosion resistance of anodic oxide layers on aluminum, necessitating a systematic anal. to understand a relationship between the PAA process and corrosion behaviors.This study investigated PAA effects on the morphol. and corrosion resistance of nanostructured anodic oxide layers by varying electrolyte temperature, compared with sulfuric (SAA) and oxalic (OAA) acid anodizing, followed by NiF₂ sealing. 6061 aluminum alloy was anodized in 10 wt% phosphoric acid at 100 V for 30 min at 273, 293, and 313 K.The pore diameter, porosity, and oxide layer thickness increased with increasing the electrolyte temperatureThin and irregular layers appeared at 313 K due to accelerated dissolution, resulting in the lowest corrosion resistance.The PAA sample at 293 K showed a c.d. of - 0.75 V in potentiodynamic polarization, comparable to the sealed SAA and OAA samples, despite a thinner oxide layer.The barrier layer resistance of the PAA sample at 293 K was 1.60 x 10⁷Ω cm², similar to SAA (1.44 x 10⁷Ω cm²) and OAA (1.27 x 10⁷Ω cm²).The barrier layer thickness was estimated at 60.4 nm for the PAA sample at 293 K, while minimal thickness was found at 273 and 313 K.A uniform AlPO₄ formation in PAA provides an effective protective barrier to significantly improve corrosion resistance without a requirement of sealing.This first detailed study on PAA provides benchmark processes and data that can be utilized for the rapid production of corrosion-resistant aluminum-based engineering components.Graphic Abstract:

The preparation and performance analysis of high-entropy phosphate high-temperature resistant adhesives

作者: Hu, Zhanming ; Wei, Xuemin ; Xiao, Bo ; Li, Jingjing ; Qi, Chenchen ; Wang, Mingchao ; Ji, Xiaojian

In response to the weak bonding effect caused by the difference in thermal expansion between aluminum phosphate adhesive and alumina, a series of high-entropy phosphate adhesives (8.9 x10^-1 K^-1) with high thermal expansion matching to alumina (9 x10^-6 K^-1) were developed and analyzed.The adhesive could cure at room temperature and evolve into a stable high-entropy ceramic structure during heat treatment.Among them, (La_0.2Ce_0.2Sm_0.2Nd_0.2Eu_0.2)PO₄ adhesive showed the best bonding performance since the generation of high-entropy ceramic.Without adding other additives, it provided a bonding strength of 14.8 MPa for alumina, 74 times that of aluminum phosphate.The strength retention rate remained at 40% after 20 thermal cycles from room temperature to 1500 ° C.The adhesion mechanism relied on the combination of mech. interlocking, chem. bond adhesion and electrostatic interactions, and reinforced by the four core effects of high-entropy structure.High-entropy adhesives showed great prospects in aerospace, electronics, medical, and other fields.

春节吃多消化不良？为您送上节后消食用药指南以及药物院端销售分析

春节期间走亲访友，聚餐频繁，不少人开启了大吃大喝模式，一不小心就导致消化不良，市场上治疗消化不良的药物品种繁多，胃痛、胃胀、胃酸...该如何对症下药呢？在此为大家送上一份节后消食用药指南，为胃肠道减轻负担，更好的投入日常工作生活轨道吧！消化不良是指位于上腹部的胃部及十二指肠一种或一组症状，主要表现为上腹痛、上腹部灼感、餐后饱胀和早饱感或恶心、呕吐及嗳气等。按病因可分为器质性消化不良和功能性消化不良。如果是由某些疾病引起的器质性消化不良，会直接按原发病去诊治。因此，通常提及的“消化不良”为功能性消化不良(functional dyspepsia，FD)。根据《2022中国功能性消化不良诊治专家共识》，FD分为上腹痛综合征（EPS）和餐后不适综合征（PDS）。常用的治疗消化不良的药物可以分为以下几类：1. 抑酸药：这类药物主要用于治疗胃酸过多引起的消化不良，如胃炎、胃溃疡等。常见的抑酸药有质子泵抑制剂(如奥美拉唑、雷贝拉唑等)、H2受体阻滞剂(如雷尼替丁、法莫替丁等)。2. 保护胃黏膜药：这类药物主要用于保护胃黏膜，防止胃酸对胃黏膜的损伤。常见的保护胃黏膜药有铋剂(如胶体铋、枸橼酸铋钾等)、磷酸铝、硫糖铝等。3. 抗胃酸返流药物：减少胃酸返流到食道的药物，主要包括质子泵抑制剂、H2受体拮抗剂以及利福平等。4. 促胃肠动力药：这类药物主要用于增强胃肠蠕动，加快食物的消化和吸收。常见的促胃肠动力药有多潘立酮、莫沙必利等。5. 消化酶制剂：这类药物主要用于帮助食物的消化，尤其是对于消化酶缺乏引起的消化不良。常见的消化酶制剂有胰酶、糖酶、脂肪酶等。6. 益生菌和益生元：调节肠道菌群平衡，改善消化功能，常用的包括乳酸菌、双歧杆菌、菊粉等。7. 中药：中医认为消化不良与脾胃虚弱、湿热内阻等因素有关，因此常用的中药有健脾胃的药物(如六君子汤、香砂六君子汤等)、清热化湿的药物(如黄连温胆汤、三黄片等)等。《2022中国功能性消化不良诊治专家共识》中提到，抑酸药物质子泵抑制剂PPI和H2受体拮抗剂可作为上腹痛综合征（EPS）的首选治疗；胃肠促动药可作为餐后不适综合征（PDS）的首选治疗；中成药治疗对改善功能性消化不良症状有较好的疗效；消化酶可改善功能性消化不良患者的部分症状。此外，我国为上消化道恶性肿瘤高发国家，推荐初诊消化不良患者及时进行胃镜检查。了解了基本的药物分类，消化不良类药物在院端的销售表现如何呢?让我们一探究竟。以下数据来自中国医药工业信息中心的PDB药物综合数据库，欢迎扫描文末二维码试用。据PDB药物综合数据库统计，近3年来，治疗消化不良类药物在院端的销售趋势趋于平稳，2021年全国医院市场销售额为38.51亿元，2022年为37.68亿元，2023年Q1-Q3销售额达到30.27亿元。图1: 2021-2023治疗消化不良药销售额统计数据来源：PDB药物综合数据库-国内院端放大，中国医药工业信息中心按照ATC四级分类统计，中药类、止泻药中的止泻微生物类、酶抑制剂类助消化药稳居TOP3榜单。以2023年前三季度销售额为例统计，其中，中药类销售额达到12.3亿元，占比40.65%；止泻微生物销售额为9.77亿元，占比32.28%；酶抑制剂类助消化药销售额为5.44亿元，占比17.97%。图2: 2021-2023治疗消化不良药不同类别药物销售额数据来源：PDB药物综合数据库-国内院端放大，中国医药工业信息中心统计前三季度每季度的TOP 10销售产品发现，销售冠军来自杭州远大生物制药有限公司的双歧杆菌四联活菌片（商品名：思连康），每季度销售额均突破1亿元，销售额占比＞10%。该产品属于止泻微生物类，用于治疗与肠道菌群失调相关的腹泻、便秘、功能性消化不良，于2020年进入国家医保目录。此外，10款产品中近一半都属于中成药，神曲消食口服液、小儿消积止咳口服液、健胃消食口服液、枳术宽中胶囊均有亮眼的销售表现。图3: 2023 Q1-Q3治疗消化不良药销售额TOP 10产品数据来源：PDB药物综合数据库-国内院端放大，中国医药工业信息中心以上药物的使用需要根据患者的具体病情和医生的建议，不同的人可能需要不同的治疗方案。同时，药物治疗只是治疗消化不良的一部分，患者还需要调整饮食习惯，避免过度饮食，保持良好的生活习惯，多多运动。END如需获取更多数据洞察信息或公众号内容合作，请联系医药地理小助手微信号：pharmadl001

Maternal Vaccine Can Prevent Group B Strep in Young Infants

FRIDAY, July 21, 2023 -- A hexavalent capsular polysaccharide (CPS)-cross-reactive material 197 glycoconjugate vaccine (GBS6) can prevent invasive group B streptococcus in young infants, according to a study published in the July 20 issue of the New England Journal of Medicine . Shabir A. Madhi, M.D., Ph.D., from the South African Medical Research Council Vaccines and Infectious Diseases Analytics Research Unit in Johannesburg, and colleagues conducted an ongoing phase 2, placebo-controlled trial involving pregnant women to assess the safety and immunogenicity of a single dose of various GBS6 formulations and analyzed maternally transferred anti-CPS antibodies. In a parallel seroepidemiologic study, serotype-specific anti-CPS immunoglobulin G (IgG) concentrations that were associated with a reduced risk for invasive disease among newborns were assessed to define putative protective thresholds. The researchers found that among infants in the seroepidemiologic study, naturally acquired anti-CPS IgG concentrations were associated with a reduced risk for disease. IgG thresholds of 0.184 to 0.827 µg/mL were determined to be associated with 75 to 95 percent reductions in the risk for disease. There were no GBS6-associated safety signals among mothers or infants. Across the trial groups, the incidence rates of adverse events and serious adverse events were similar for mothers and infants; the groups that received GBS6 containing aluminum phosphate had more local reactions. GBS6 induced maternal antibody responses to all serotypes; depending on the dose, maternal-to-infant antibody ratios were approximately 0.4 to 1.3. "The potential protective concentrations that are reported herein are based on a single seroepidemiologic study," the authors write. "Future studies are needed to better define these immunologic relationships." The study was funded by Pfizer. Abstract/Full Text Editorial (subscription or payment may be required) Posted July 2023
