“…Regarding the CC, unlike the two mentioned residues, it was only obtained after the shelving process; once the samples were partially dehydrated with a mass of approximately 2.0 Kg, they were again dried at a temperature of 60 • C until a constant mass was obtained. Once the samples were dry, this were triturated to a particle size of 180 µm, given that the literature references sizes range from 75 to 251 µm [16].…”

In the present investigation, results obtained from the process of the biosorption of Zn(II) in synthetic wastewaters are presented, using three agricultural wastes (coffee pulp, banana pseudo-stem, and corncob). Firstly, the percentage of lignin and cellulose for each material was determined. Then, using the free software XLSTAT, the waste with the highest removal for this metal was selected and, after this, the optimum pH, kinetics, adsorption isotherm, and point of zero charge (pHpzc) were found. Finally, a comparison with other lignocellulosic materials derived from banana, corn, and coffee crops was carried out. According to the results obtained, coffee pulp was the material that showed a high removal compared to the other two (63.58%), for which the optimum pH was 5.0 units. The kinetic model, which was adjusted to the process of biosorption, was the pseudo second order of Ho and McKay, which in turn presented an isotherm of Langmuir’s linearized model where the maximum adsorption capacity with that waste was 13.53 mg × g−1, obtained with a particle size of 180 µm, contact time of 90 min at 100 RPM, temperature of 25 °C, and pHpzc 3.95 units. Lastly, the authors state that this type of agricultural waste can be used as a green technology in the treatment of wastewater, particularly in the removal of the aforementioned pollutant, in order to fulfill goals 3.9 and 6.9 of the Sustainable Development Goals of the 2030 Agenda; to the level of challenge of the research, the authors propose for the future to carry out the implementation of this type of waste, without chemical modification, in the treatment of wastewater for the removal of the mentioned pollutant in a pilot study with different wastewaters and industries.

“…Adsorption can be categorized into two which are based on physical and chemical [73]. Physical adsorption occurs when the absorbent and adsorbate are attracted by the weak van der Waals forces, hydrogen bonding, and dipole-dipole interaction [86]. It electrostatically attracts the metal ions through the surface of materials.…”

Manganese is one of the most abundant heavy metals that has been detected in surface water lately. This has become an environmental concern as manganese pose negative impacts on the ecosystem and water supply. The current water treatment process faces challenges in the efficient treatment of manganese at a low cost. This paper reviews the sources, occurrences and negative impacts of manganese towards living organisms as well as the treatment using the adsorption process. The potential synthesizes of low cost and environmentally friendly agricultural waste adsorbent to remove manganese is elucidate in this paper. The outcomes have the potential to reduce manganese concentration in the surface water and minimize the cost of water treatment.

“…Platelets are also called blood chips, megakaryocyte cytoplasmic fragments that do not have a nucleus and are formed by bone marrow (Kosasih, 2008). The normal platelet level ranges between 150,000 -400,000 cells/μl of blood (Lefever Joyce, 2008).…”

Thrombocytopenia or platelet deficiency is a condition, in which platelet level in the blood circulation is below normal, which is less than 150,000 cells/µl. Thrombocytopenia is classified into some conditions, including decreased platelet production, increased need for platelets, and other thrombocytopenia. The need for increased platelets can be subdivided into primary immune thrombocytopenia, secondary immune thrombocytopenia, non-primary ITP, and thrombocytopenia that are not immune-mediated. Several cytokines play a role in the process of thrombocytopenia, one of which is Interleukin-17 (IL-17) that will be further discussed in this study. A previous study reported that IL-17 production increased in ITP and cITP patients. The objective of this study was to analyze the IL-17 levels and figure out the differences in IL-17 levels in the serums of patients with primary ITP and secondary ITP. The samples were taken from Wahidin Sudirohusodo Hospital and the specimens were examined in the Research Unit Laboratory of the Faculty of Medicine, Universitas Hasanuddin/Hospital of Universitas Hasanuddin. The comparative test resulted in p-value = 0.005, where p <α = 0.05; and therefore, there was a significant difference between IL 17 levels in ITP and non-primary ITP.
