Meloxicam(MLX) is an anti-inflammatory drug susceptible to variations and crystalline transitions. In compounding pharmacies, the complete crystallographic evaluation of the raw material is not a routine procedure. We performed a complete crystallographic characterization of aleatory raw MLX samples from compounding pharmacies. X-ray diffraction indicated the presence of two crystalline forms in one sample. DSC experiments suggested that crystallization, or a crystal transition, occurred differently between samples. The FTIR and ~1H NMR spectra showed characteristic assignments.^(13)C solid-state NMR spectroscopy indicated the presence of more than one phase in a sample from pharmacy B. The Hirshfeld surface analysis, with electrostatic potential projection, allowed complete assignment of the UV spectra in ethanol solution. The polymorph I of meloxicam was more active than polymorph III in an experimental model of acute inflammation in mice. Our results highlighted the need for complete crystallographic characterization and the separation of freely used raw materials in compounding pharmacies,as a routine procedure, to ensure the desired dose/effect.

Occurrence of Delirium and Length of Stay of Patients in the Intensive Care Unit

引用

Journal of Biosciences and Medicines 2021年第8期9卷 1-9页

作者： Aparecida Sátira da Silva Machado Mayara Rabello Teixeira Alves Daniella Nogueira Vieira Sara Ellias de Sousa felipe rodrigues Maia Daniel Almeida da Costa Leandro Raider The Medical School at the Center of Higher Education of Valenç a Unifaa Brazil

Introduction: The delirium has received little attention from professionals working in the intensive care unit, mainly due to the fact that this is, rarely, the primary reason for patient admission. Given the high prevalence of delirium in an intensive care environment, the current guidelines recommend the daily assessment of delirium and a multidisciplinary approach. Delirium is a frequent and severe form of acute brain dysfunction, as well as an important source of concern in critical care. Objective: To assess the occurrence of delirium and time of stay in the intensive care unit. Method: This is a quantitative, descriptive study, with a cross-sectional design, which was carried out in a university hospital located in the interior of the State of Rio de Janeiro. The sample consisted of 89 patients, of both sexes, aged between 24 and 92 years. The RASS and CAM-ICU scales were used to assess delirium. The data were collected every 12 hours, for 3 months, 7 days a week and in an uninterrupted manner. Results: Were evaluated 89 patients, of which 16 were excluded according to the scale criteria, leaving 73 patients. After evaluation, 22 patients were diagnosed with delirium and 51 patients without delirium. Of the patients who presented delirium, 13 deaths and 9 had high to the nursery. Of the patients who did not have delirium, 40 had high to the nursery and 11 deaths. Patients with delirium had an average hospital stay of 23.25 days and patients who did not have delirium had an average of 4.5 days hospitalization. Conclusion: We can infer that the longer the patient spends in the intensive care unit, the greater the chance of delirium occurring. Therefore, preventive and interventional measures are necessary to decrease the mortality rate in patients with delirium and early detection is an excellent tool to improve this outcome.

Background: Mesenchymal stromal cells (MSC) are being tested for the treatment of immune diseases. MSC are present in several adult tissues which milieu may influence MSC behavior particularly under inflammatory conditions. Additionally, culture conditions also can modify cell function or state of activation. Methods: To address the influence of the MSC source on its characteristics, we studied a xenofree, platelet lysate supplemented MSC from dental pulp, adipose tissue and bone marrow, co-cultured with isolated T cells and PBMC subset, and studied the effect of culture animal or human supplements immunomodulatory effect. Results: All three sources were efficient in inhibiting T cells. Among all MSC sources, as also described by others, adipose MSC was capable to significantly induce Treg phenotype and decrease T CD8+. Furthermore, comparing fetal bovine serum and platelet lysate, results demonstrate that platelet lysate alone is capable to induce immunomodulatory phenotype. Additional studies have to be made to elucidate the PL immunomodulatory effect.

3D printed millireactors for process intensification

引用

Chinese Journal of Chemical Engineering 2020年第1期28卷 180-190页

作者： Harrson S.Santana Alan C.rodrigues Mariana G.M.Lopes felipe N.Russo Joao L.Silva Jr Osvaldir P.Taranto School of Chemical Engineering University of CampinasBrazil Federal Institute of Education Science and Technology of South of Minas GeraisBrazil

The scope of the present research aims at demonstrating the 3D printing use in the manufacturing of microchannels for chemical process applications. A comparison among digital model processing applications for 3D print(slicers) and a print layer thickness analysis were performed. The 3D print fidelity was verified in several devices, including the microchannels’ printing with and without micromixer zones. In order to highlight the 3D print potential in Chemical Engineering, the biodiesel synthesis was also carried out in a millireactor manufactured by 3D printing. The millireactor operated under laminar flow regime with a total flow rate of 75.25 ml·min^-1(increment of about 130 times over traditional microdevices used for biodiesel production).The printed millireactor provided a maximum yield of Ethyl Esters of 73.51% at 40 ℃, ethanol:oil molar ratio of7 and catalyst concentration of 1.25 wt% and residence time about 10 s. As a result of flow rate increment attained in the millireactor, the number of required units for scaling-up the chemical processes is reduced. Using the approach described in the present research, anyone could produce their own millireactor for chemical process in a simple way with the aid of a 3D printer.
