    Hospital waste is one of the urban wastes produced by hospitals, clinics, medical research centers, and pharmacies. The management of healthcare waste includes production, storage and collection, transportation, processing and disposal, and preventing the production of waste materials and care. After disposal and preliminary treatment, it is one of the characteristics of healthcare waste management, which has been emphasized in these management systems due to the hazardous nature of these materials. This is an important environmental challenge in most developing countries. Failure to properly identify, separate, store and disinfect hazardous hospital waste has caused health problems and environmental pollution. According to the World Health Organization standard, hospital hazardous waste is divided into nine groups, including infectious, pathological, chemical, genotoxic, sharp and sharp, pharmaceutical, heavy metal waste, pressurized and radioactive waste. Waste produced in healthcare centers includes infectious waste, non-infectious solid waste and many dangerous substances. Treatment and disposal of hospital waste is done with the aim of changing the biological characteristics of waste materials in order to eliminate or minimize their ability to cause harm. In the existing laws of the United States of America, 20-25% of infectious hospital waste is meant, and the Center for Disease Control in this country mentions the mentioned amount as 3-5%. In general, the amount of infectious and non-infectious waste in hospitals depends on various factors that need to be investigated on a case-by-case basis to know their exact amount.

    Cinnamon is applied for diabetes and insulin resistance as a plant medicine. In this study, DFT calculations to consider the pregnancy function role of cinnamon compounds was done by B3LYP/6-311G. Thermodynamics properties, molecular electronics, docking of cinnamon compounds with estrogen, testosterone and progesterone and drug parameters calculated the results obtained among sexual hormones; progesterone acts with the chemical component of Cinnamon.

    The disadvantages of conventionally utilized techniques for the synthesis of organic and inorganic compounds include costliness, non-eco-friendliness, less effectiveness, and unsuitability in large-scale procedures. Green procedures minimize injurious chemical compounds and equipment, are inexpensive, facile, produce no detrimental chemicals, and are highly efficient. Nano-scale significantly raises the potentiality of compounds and the green methods of synthesis in synthetic chemistry are superior alternates and effective relative to conventionally used techniques. Calcium oxide nanoparticles (CaO-NPs) are of value in adsorption, antimicrobial activities, catalysis, and adsorption. Green synthesis is the most preferable formulation technique because of using contamination-free chemical compounds and encouraging the application of non-toxic solvents, including water and plant extracts. This investigation aimed to propose the synthesis of CaO nanoparticles by an environmental-friendly green synthesis by P. atlantica leaf extract. The CaO-NPs were characterized in detail. In our investigation, the UV-Vis spectrums were determined in wavelengths ranging from 270 to 350 nm, suggesting

    The prevalence of oral squamous cell carcinoma (OSCC) has increased in the last 2 decades. For the treatment of this disease, various herbal anticancer agents have been introduced. In this study, for the first time, we analyzed the apoptotic and cytotoxic effects of herbal plants, including Anacyclus pyrethrum, Terminalia chebula, and Brassica nigra, in KB cancer cell lines. For analyzing the cytotoxic effects of ethanol extracts, MTT reduction assay was performed in the KB cells. Moreover, the apoptosis-inducing effect of plants on KB cells was assessed using TUNEL and DNA fragmentation assays. The results showed that Anacyclus pyrethrum and Terminalia chebula extracts significantly inhibited cell viability. TUNEL and DNA fragmentation assays showed that the main mechanism of cell death was apoptosis induction by Anacyclus pyrethrum and Terminalia chebula extracts. Our results suggest that these ethanol extracts may contain bioactive constituents, which can be helpful in OSCC treatment.

    Nanotechnology is a fascinating research area as a result of producing nanoparticles with different shapes, sizes, chemical composition, dispersity, and their several applications for the human being. Manipulation, creation, and using metallic nanoparticles is greatly important considering reduction of dimensions. Therefore, unique thermal, electronic, and optical characteristics are obtained. The biosynthesis approaches of nanoparticles are prioritized compared to physical and chemical processes as a result of the lower time costs and energy. Green synthesis of nanoparticles is an eco-friendly technique using natural solvents. The current work includes the eco-friendly, and green synthesis of CuNPs utilizing Cu(NO3)2.H2O solution and Peel of Pomegranate extract. Various bio-components exist in the Pomegranate Peel extract works as a reducing agent for this synthesis, . The diminant surface plasmon resonance (SPR) peak achieved at 350 nm in UV-Visible spectra confirmed the formed CuNPs. Based on SEM analysis, the spherical uniformly and morphology sized particles (36.99-55.17 nm) were obtained. The green synthesis of copper nanoparticles mediated by the Pomegranate Peel extract was clearly illustrated by FTIR spectrum. The structural characterization was performed utilizing XRD in line with reflections of the face-centered cubic (fcc) phase of the CuNPs (111, 200, 220, and 400). It was found that biologically synthesized copper nanoparticles effectively controlled the progression of human pathogens, namly Salmonella.

    Herein, magnetic metal-organic framework nanocomposite consisting of aminodibenzo-18-crown-6 magnetite nanoparticles and MIL-101(Cr) was synthesized. The nanoadsorbent was characterized with FT-IR, VSM, SEM and XRD. The nanoadsorbent was suitable for extractive preconcentration of Tl(I) and Tl(III) ions. The total amount of thalliumwas then determined by reducing Tl(III) to Tl(I) by hydroxylamine hydrochloride and also extracting it. .Experimental design was employed for optimizing the affective variables. Under the opted conditions, limit of detection and relative standard deviation (%) of the developed method was as low as 1.5 ng L−1, the quantification limit is 5.0 ng L−1, the linear range extends from 5 to 400 ng L−1, and is <12% (for n = 5 at levels of 5, 50 and 250 ng L−1), respectively. Maximum sorption capacity of the sorbent for Tl(I) and Tl(III) ions was 197 mg g−1. this method was utilized for analysis of a certified reference material (NIST SRM1643d water sample and to various real water samples.
