Pharmaceutical plant sites play a significant role in the dissemination of antibiotic resistance genes (ARGs) into the environment. It is imperative to comprehensively monitor of ARGs across various ...environmental media at these sites. This study focused on three pharmaceutical plants, two located in North China and one in South China. Through metagenomic approaches, we examined the composition, mobility potential, and bacterial hosts of ARGs in diverse media such as process water, groundwater, topsoil, soil cores, and pharmaceutical fermentation residues across diverse environmental matrices, including topsoil, soil cores, process water, groundwater, and pharmaceutical fermentation residues. We identified a wide array of ARGs, comprising 21 types and 740 subtypes, with process water exhibiting the highest abundance and diversity. Treatment processes varied in their efficacy in eliminating ARGs, and the clinically relevant ARGs should also be considered when evaluating wastewater treatment plant efficiency. Geographical distinctions in groundwater ARG distribution between northern and southern regions were observed. Soil samples from the three sites showed minimal impact from pharmaceutical activity, with vancomycin-resistance genes being the most prevalent. High levels of ARGs in pharmaceutical fermentation residues underscore the necessity for improved waste management practices. Metagenomic assembly revealed that plasmid-mediated ARGs were more abundant than chromosome-mediated ARGs. Metagenome-assembled genomes (MAGs) analysis identified 166 MAGs, with 62 harboring multiple ARGs. Certain bacteria tended to carry specific types of ARGs, revealing distinct host-resistance associations. This study enhances our understanding of ARG dissemination across different environmental media within pharmaceutical plants and underscores the importance of implementing strict regulations for effluent and residue discharge to control ARG spread.

Membrane fouling is the vulnerable point of polyamide (PA) reverse osmosis (RO) membranes in industrial wastewater treatment (especially pharmaceutical plant effluent). The deposition and adsorption of foulants on the PA layer greatly reduce the permeability selectivity of the membrane and increase maintenance costs. In this work, a simple irradiation strategy was used to graft hydrophilic polymers on the membrane surface without any catalysts and initiators, and an excellent hydrophilic and antifouling modified RO membrane was developed. The successful introduction of Poly(vinyl alcohol)(PVA) onto RO membrane surface was confirmed through systematic surface characterization (13C NMR, ATR-FTIR, XPS, SEM, and AFM). The membrane M−2 with a PVA modifier concentration of 1.0% hasremarkable hydrophilic properties (water contact angle of 24.93°) and excellent separation efficiency (salt rejection up to 99.4%). The antifouling property of the modified membrane is significantly enhanced due to the synergistic effect of the hydrophilic component and the roughness. In the bovine serum albumin (BSA) antifouling tests, the irreversible flux decline rate (DRir) of membrane M−2 was as low as1.7% and the flux recovery ratio (FRR) values increased from 87.6% to 98.3% compared to pristine membrane.Importantly, the membrane modified with PVA shows a high foulant removal efficiency (COD > 99.5%) in the actual pharmaceutical plant effluent treatment, and the performance is stable after continuous operation for 28 days. The proposed simple co-grafting strategy also opens up new possibilities for the optimization or modification of other membranes (e.g., nanofiltration and ultrafiltration). Simultaneously, the prepared modified membrane has stable performance, simple and efficient method, and can also be applied in desalination and other industrial wastewater treatment fields.
The effect of different levels of Scrophularia striata extract in normal and challenged conditions with E. coli on performance, carcass characteristics, cellular immune response, blood antioxidant ...status, intestinal histo-morphometry, and microbial population (E.coli and Lactobacillus) of Cobb 500 broilers were evaluated. The experiment was performed in a complete block design with a 2 × 4 factorial arrangement with five replications of 10 birds each for 35 days in two separated halls include challenge (C) and non-challenge (N) with similar experimental conditions. Experimental treatments in two breeding halls were: 1) basal diet or control (CONT), 2) basal diet + 0.1 g/kg of herbal extract (EXTR 1), 3) basal diet +0.2 g/kg of herbal extract (EXTR 2), 4) Basal diet +0.1 g/kg an antibiotic (Oxytetracycline) (ANTB). On the 16th and 24th days of the experiment, one dose of 1×107 CFU K99 E. Coli was gavaged to chickens in a challenged conditioned hall. The results showed that average body weight and daily weight gain in the whole period (days 35 and 1-35) in EXTR 2 was better than the control treatment (P < 0.05). The percentage of breast weight in the ANTB was significantly different from the control treatment (P < 0.05). Glutathione peroxidase (GPX) in EXTR 2 was better than the control treatment (P < 0.05). Malondialdehyde (MDA) in EXTR 1 was significantly lower than the control group (P < 0.05). The values of E. coli in the treatment ANTB were less than control treatment (P < 0.05). Lactobacillus value in treatment EXTR 2 was higher than control treatment (P < 0.05). The value of total immunoglobulin in 28 days in ANTB, EXTR 1, and EXTR 2 were significantly higher than that of control treatment (P < 0.05). The length of villi was affected by treatments (P < 0.05). In conclusion, dietary inclusion of 0.2 g/kg of Scrophularia striata extract may improve the health status of the birds during E. coli challenge.
A series of ultrafiltration (UF) membranes based on mixed matrix of chromium-doped strontium titanate (SrTiO3–Cr) photocatalyst and polyvinylidene difluoride (PVDF) were systematically prepared by ...non-solvent induced phase inversion technique. Porous PVDF membrane and mixed matrix membranes (MMMs) incorporated with 3–10 wt% SrTiO3–Cr were produced in the UF range using polyethylene glycol as a porogen additive. The crystal morphology and electronic property of as-synthesized Cr-doped SrTiO3 nanoparticles were characterized by XRD and UV–Vis DRS. We found that the SrTiO3–Cr nanoparticles are cubic perovskite structure of approximately 30–40 nm in size with a low band gap energy of 2.05 eV. The morphology, surface roughness, hydrophilicity and textural properties of SrTiO3–Cr/PVDF MMMs were comprehensively characterized using field emission-scanning electron microscope with energy-dispersive X-ray spectroscopy, atomic force microscope, sessile drop technique, and capillary flow porometer. The SrTiO3–Cr was observed to be homogeneously dispersed in all the MMMs and provided additional anti-fouling properties from Bovine Serum Albumin (BSA) protein. The membrane UF property and tri-cycling performance were evaluated under three distinct protocols in (1) Dark, (2) constant UVA exposure, and (3) UVA during post-treatment clean only. By increasing the SrTiO3–Cr concentration, the MMMs displayed an improved homogeneity and macropore distribution with enhanced water permeability given by 51–110 LMH bar−1 pure water flux and 37 to 45 LMH bar−1 BSA water flux in the Dark. A consistently high BSA rejection of 95% and an improved anti-fouling property under constant UVA irradiation were achieved due to a combination of photo-induced hydrophilic and photocatalytic effect. Also, a significant improvement in UF performance in terms of membrane flux recovery was observed in the 3rd protocol signifying that the effect of protein fouling on membrane filtration was further reduced due to a lower degree of BSA fragment deposition in the membrane pores. The findings in this study dramatically lower the operational constraints (transmembrane pressure, membrane cleaning, use of UVA) in the protein filtration process and offer an innovative membrane material for the research of photo-induced, anti-fouling membranes for protein separation applications.

This study proposed a new optimization-based decision model for an enterprise resource planning and production scheduling of a pharmaceutical intermediates manufacturing plant. To do this work, we first define the inflow and outflow information as well as the model structure, and develop an optimization model to minimize the production time (i.e., makespan) using a mixed integer linear programing (MILP). The unique feature of the proposed model is that the optimal process scheduling is established based on real-time resource logistics information using a radio frequency identification (RFID) technology, thereby theoretically requiring no material inventories. essential information for process operation, such as the required amount of raw materials and estimated arrival timing to manufacturing plant, is used as logistics constraints in the optimization model to yield the optimal manufacturing scheduling to satisfy final production demands. We illustrated the capability of the proposed decision model by applying the optimization model to two scheduling problems in a real pharmaceutical intermediates manufacturing process. As a result, the optimal production schedule and raw materials order timing were identified to minimize the makespan while satisfying all the product demands.

Insulin therapy is the mainstay of treatment in patients with type 1 diabetes, while diet and lifestyle changes, and if left untreated, insulin therapy are effective in treating type 2 diabetes. ...Research has shown that the oldest treatment for diabetes was the use of herbs. Thus, various medicinal plants were used to relieve many of the complications of diabetes. This study aimed to assess the effectiveness of various medicinal plants in the treatment of diabetes. The data on medicinal plants and diabetes were collected from related articles published from 2014 to 2021 in reputable databases such as Cochrane, PubMed, Scopus, ScienceDirect, Embase, and SID. Data analysis showed that medicinal plants such as Allium sativum, Cinnamomum verum, Trigonella graecum foenum, Silybum marianus, Citrullus colocynthis, Abelmoschus esculentus, Eryngium, Coriandrum sativum L, and Zingiber officinale were the most frequently used herbs in the treatment of diabetes. Medicinal plants can reduce blood sugar in patients due to having effective medicinal compounds and natural antioxidants and due to the least side effects but longer treatment period.Keywords: Diabetes; Medicinal plants; Remedy; Pharmaceutical Plant
The evaluation of faults in a multipurpose pharmaceutical pilot plant used for production of polymer particles was performed, integrating traditional Fault Tree Analyses (FTA) and Monte Carlo ...procedures and employing tools of the quality risk management methodology for production of medicines. The plant was divided into four basic processes: (i) receipt and sampling of materials; (ii) treatment of purified water; (iii) reaction; and (iv) lyophilization and purification. For each process, the most critical failure was selected, and the FTA was built. Selection of basic events considered the most important effects on the final quality of the medicine. Then, the FTA was reduced to basic events using Boolean algebra. The quantitative assessment was made by assigning failure rate values for each event. The reliability data of the failure rates were based on the literature that deals with similar processes. The frequencies for each fault were determined through Monte Carlo simulations, considering that fault probability distributions followed the exponential distribution. When failure rate (ʎ) data are available, the quality management can establish a prediction of plant behavior over a period. This scenario is consistent and coherent with practices of pharmaceutical sites, since occurrence of high rates of failure must be corrected immediately in order to preserve the safety of the operation.

Leptadenia reticulata, a member of Asclepiadaceae, is a pharmaceutically important plant and has a number of medicinal properties. We describe here first time an efficient in vitro regeneration protocol using leaf of mature plant as explant. Callus was induced from cut ends of leaf inoculated on MS medium containing 1.0mgl−1 each of 2,4-D and BAP+additives. MS medium having a concentration of 2,4-D (0.5mgl−1) and BAP (0.5mgl−1) was found optimum for callus proliferation. Shoot differentiation from proliferated callus was observed on MS medium containing BAP alone or in combination with IAA or NAA. The maximum number (30.70±1.70) of shoots with average length (8.62±0.32cm) was produced on MS medium having a combination of BAP (0.5mgl−1) and NAA (0.1mgl−1). The shoots (81.6%) were rooted in vitro on one-fourth strength MS medium supplemented with IBA (1.5mgl−1) and 100mgl−1 AC. For ex vitro rooting (85.0%), shoot bases were pretreated with auxin (IBA 200mgl−1) for 3min. Rooted plantlets by both methods were successfully acclimatized under the green house conditions with about 95% survival rate. The present protocol may be applicable for (i) large scale plant production (ii) germplasm conservation (iii) genetic transformation (iv) protoplast fusion and (v) superior somaclonal variants selection of this multipurpose medicinally important endangered plant.
Granulators play a key role in many pharmaceutical processes because they are involved in the production of tablets and capsule dosage forms. Considering the characteristics of the production ...processes in which a granulator is involved, proper maintenance of the latter is relevant for plant safety. During the operational phase, there is a high risk of explosion, pollution, and contamination. The nature of this process also requires an in-depth examination of the time-dependence of the process variables. This study proposes the application of canonical variate analysis (CVA) to perform fault detection in a granulation process that operates under time-varying conditions. Beyond this, a different approach to the management of process non-linearities is proposed. The novelty of the study is in the application of CVA in this kind of process, because it is possible to state that the actual literature on the theme shows some limitations of CVA in such processes. The aim was to increase the applicability of CVA in variable contexts, with simple management of non-linearities. The results, considering process data from a pharmaceutical granulator, showed that the proposed approach could detect faults and manage non-linearities, exhibiting future scenarios for more performing and automatic monitoring techniques of time-varying processes.
