Case of Refractory Thrombocytopenia in Pregnancy Associated with May-Heglin Anomaly after Repeated Platelet Transfusions

引用

Open Journal of Obstetrics and Gynecology 2024年第7期14卷 1083-1090页

作者： Aalaa A. Wahab Marzooq Aseel Ahmed husain Aayat Jaaffar Naseeb Salmaniya Medical Complex Manama Bahrain

May-Heglin Anomaly is an autosomal dominant disorder characterized by macrothrombocytopenia with a platelet function that is usually preserved. Platelets play an essential role in hemostasis. During pregnancy, a woman is susceptible to complications, including postpartum hemorrhage. Monitoring patients’ hemostatic functions and observing the patient’s clinical picture to maintain patient safety is paramount, while avoiding unnecessary therapeutic measures. This case report presents a rare instance of May-Heglin Anomaly (MHA) in a 35-year-old pregnant patient, with refractory thrombocytopenia despite receiving multiple platelet transfusions. Initially referred to as gravida 5 para 4 with severe thrombocytopenia at 28 weeks gestation, throughout her pregnancy, she was closely monitored and received over 40 units of platelets, which failed to increase her platelet count significantly. She delivered a healthy baby via vaginal delivery at 38 weeks, with her platelet count still critically low. This report highlights the challenges of managing MHA in pregnancy, the inefficacy of standard thrombocytopenia treatments such as platelet transfusion in MHA patients, and the importance of tailored management strategies to ensure maternal and fetal safety.

Hydrocarbon Potential of the Triassic-Jurassic Sediments in Southeast Sulawesi, Indonesia, Based on Lithofacies and Geochemical Analysis

引用

Open Journal of Geology 2024年第8期14卷 723-745页

作者： Muhammad Sulhuzair Burhanuddin Shun Chiyonobu Takuto Ando Anggi Yusriani Ratna husain Suryawan Asfar Graduate School of International Resources Sciences Akita University Akita Japan Geological Department of Hasanuddin University Makassar Indonesia Geoservices Laboratory South Jakarta Indonesia Geological Department of Haluoleo University Kendari Indonesia

Triassic-Jurassic carbonates widely distributed in Eastern Indonesia are believed as oils source rock. The Mesozoic Tokala Formation exhibit source rock potential, as evidenced by high contents of organic matter. Recent exploration has been conducted in southeastern Sulawesi, targeting the Mesozoic intervals. Therefore, in this study, we attempted to determine source rock potential of Tokala Formation outcropped in southeastern Sulawesi area and its capability to generate hydrocarbon. Five distinct lithofacies were delineated, emphasizing lithological and mineralogical features: foraminifera wackestone (FW), lime mudstone (LM), massive bioturbated calcareous-argillaceous shale (MBCAS), weakly laminated argillaceous-calcareous shale (WLACS), and strongly laminated calcareous-argillaceous shale (SLCAS). Subsequent analyses showed that carbonate-rich samples (FW and LM facies, >50% CaO) had poor source rock potential. Conversely, shale facies with moderate carbonate content (WLACS, MBCAS, and SLCAS, 15% - 50% CaO) had good to excellent source rock characteristics, qualifying them as preferable source rock. In addition, levels of SiO2 and Al2O3 should not be neglected, as these constituents play important roles in clay mineral adsorption. Laminated shale facies with moderate CaO content tended to be more promising as source rock than bioturbated facies. The shale facies of Tokala Formation indicate prospective source rock horizon.

Development of innovative tripartite partnership for China’s engagement in global health: recommendations from China-Tanzania Cooperation Project on Malaria Control

引用

贫困所致传染病(英文) 2024年第2期13卷 1-3页

作者： Ma Xuejiao Lu Shenning Ding Wei Deng Shanying Wang Duoquan Xiao Ning Mlacha Yeromin husain Lewis Zhou Xiaonong National Institute of Parasitic Diseases Chinese Center for Disease Control and Prevention (Chinese Center for Tropical Diseases Research) NHC Key Laboratory of Parasite and Vector Biology WHO Collaborating Center for Tropical Diseases National Center for International Research On Tropical Diseases Shanghai China University of Hong Kong Hong Kong China School of Global Health Chinese Center for Tropical Diseases Research Shanghai Jiao Tong University School of Medicine Shanghai China Ifakara Health Institute Dar-es-Salaam Tanzania Institute of Development Studies Brighton UK

Tripartite partnership, compared with the bilateral model, is envisioned as an opportunity to foster stronger and more trusting partnerships [1]. However, China has historically been characterized as principally reliant on bilateral engagement in global health [2]. The China-Tanzania Cooperation Project on Malaria Control was conducted by National Institute of Parasitic Diseases at China CDC and Chinese Center for Tropical Diseases Research, Ifakara Health Institute in Tanzania and funding agencies from 2015 to 2022, with an aim to explore the applicability of Chinese experience on malaria control to reduce malaria disease burden in the local context of Tanzania. In the tripartite project funded by the former UK Department for International Development (DFID) and later the Bill & Melinda Gates Foundation (BMGF), China's partners were expected to share the extensively parallel practices achieved from the control and elimination of malaria for over 70 years, UK's partners were to deliver resources and design global health strategies, while Tanzanian local staff collaborated with triangular partners to ensure the project implementation [3]. In the project, the trilateral cooperation has transparent management mechanism to ensure the concrete management and implementation of the project [4] (Additional file 1: Figure S1). This Brief is to provide recommendations for China's engagement in global health by distilling the experience from the innovative tripartite partnership of the project.

Potential of plant polyphenol oxidases in the decolorization and removal of textile and non-textile dyes

引用

Journal of Environmental Sciences 2007年第4期19卷 396-402页

作者： AMJAD ALI Khan QAYYUM husain Department of Biochemistry Faculty of Life Science Aligarh Muslim UniversityAligarh-202 002India.

In this study an effort has been made to use plant polyphenol oxidases; potato （Solanum tuberosum） and brinjal （Solanum melongena）, for the treatment of various important dyes used in textile and other industries. The ammonium sulphate fractionated enzyme preparations were used to treat a number of dyes under various experimental conditions. Majority of the treated dyes were maximally decolorized at pH 3.0. Some of the dyes were quickly decolorized whereas others were marginally decolorized. The initial first hour was sufficient for the maximum decolorization of dyes. The rate of decolorization was quite slow on long treatment of dyes. Enhancement in the dye decolorization was noticed on increasing the concentration of enzymes. The complex mixtures of dyes were treated with both preparations of polyphenol oxidases in the buffers of varying pH values. Potato polyphenol oxidase was significantly more effective in decolorizing the dyes to higher extent as compared to the enzyme obtained from brinjal polyphenol oxidase. Decolorization of dyes and their mixtures, followed by the formation of an insoluble precipitate, which could be easily removed simply by centrifugation.
