Biosynthesis of silver nanoparticles using natural compounds derived from plant kingdom is currently used as safe and low-cost technique for nanoparticles synthesis with important abilities to inhibit multidrug resistant microorganisms (MDR). ESKAPE pathogens, especially MDR ones, are widely spread in hospital and intensive care units. In the present study, AgNPs using Ducrosia flabellifolia aqueous extract were synthesized using a reduction method. The green synthesized D. flabellifolia-AgNPs were characterized by UV-Vis spectrophotometer, Scanning electron microscopy (SEM), and X-ray diffraction assays...

Objective  In recent years, endovascular methods have been developed to treat intracranial aneurysms. To date, results of endovascular treatment (EVT) for anterior communicating aneurysms (ACoAs) have never been investigated in Iran. Thus, we sought to assess the mid-term angiographic and clinical outcomes of patients with ACoAs who underwent EVT in a tertiary center. Materials and Methods  Electronic health documents of patients with ACoAs who underwent EVT from March 2019 to July 2021 were retrospectively reviewed...

BACKGROUND: In recent years, special attention has been paid to minimally invasive and conservative methods in addition to conventional surgical methods to repair tendon damage. In this regard, the effect of fat injection and graft has been of great interest due to its potential in accelerating tissue repair. We aimed to assess the clinical efficacy of fat injection along with conventional approach in patients with flexor tendon injury. METHODS: In this randomized clinical trial, 64 patients were randomly scheduled for tendon repair using the usual modified Kessler four-strand method alone or tendon repair using four-strand method and fat injection on the proximal and distal sides of the repair site in the Hazrat Fatemeh Hospital, Tehran Province, Iran in 2022 (IRCT20221206056723N1)...

BACKGROUND:  Transforaminal endoscopic lumbar diskectomy (TELD) is considered an effective treatment for lumbar disk herniation (LDH). There is a paucity of studies comparing in detail the costs and long-term clinical outcomes of TELD and open microdiskectomy (MD), especially in developing countries. Thus, we sought to provide a multidimensional insight into this matter by comparing the direct costs and long-term outcomes of TELD with those of MD. METHODS:  The electronic health records of 434 patients with LDH who underwent either TELD or MD were collected from February 2011 to October 2014...

A revival interest has been given to natural products as sources of phytocompounds to be used as alternative treatment against infectious diseases. In this context, we aimed to investigate the antimicrobial potential of Ziziphus honey (ZH) against twelve clinical bacterial strains and several yeasts and molds using in vitro and computational approaches. The well-diffusion assay revealed that ZH was able to induce growth inhibition of most Gram-positive and Gram-negative bacteria. The high mean growth inhibition zone (mGIZ) was recorded in E...

In the present study, the chemical composition of the volatile oil and methanolic extract from Ducrosia flabellifolia Boiss. was investigated. The antimicrobial, antioxidant, and anticancer activities of the methanolic extract from D. flabellifolia aerial parts were screened using experimental and computational approaches. Results have reported the identification of decanal (28.31%) and dodecanal (16.93%) as major compounds in the essential oil obtained through hydrodistillation. Farnesyl pyrophosphate, Methyl 7-desoxypurpurogallin-7-carboxylate trimethyl ether, Dihydro-Obliquin, Gummiferol, 2-Phenylaminoadenosine, and 2,4,6,8,10-dodecapentaenal, on the other hand, were the dominant compounds in the methanolic extract...

Cancer is one of the major causes of death worldwide. The repercussions of conventional therapeutic approaches present a challenge in the delivery of new effective treatments. Thus, more attention is being awarded to natural products, mainly honey. Honey could be the basis for the development of new therapies for cancer patients. The aim of this study is to assess the phytochemical profiling, antioxidant, drug-likeness properties, and anticancer activity of Ziziphus honey (ZH) derived from the Hail region of Saudi Arabia...

In consideration of the emergence of novel drug-resistant microbial strains and the increase in the incidences of various cancers throughout the world, honey could be utilized as a great alternative source of potent bioactive compounds. In this context, this study pioneers in reporting the phytochemical profiling and the antimicrobial, antioxidant, and anticancer properties of Acacia honey (AH) from the Hail region of Saudi Arabia, assessed using in vitro and molecular docking approaches. The phytochemical profiling based on high-resolution liquid chromatography-mass spectrometry (HR-LCMS) revealed eight compounds and three small peptide-like proteins as the constituents...

The interest for green synthesis of metallic nanoparticles (NPs) has acquired particular attention due to its low toxicity and economic feasibility compared with chemical or physical process. Here we carried out an extracellular synthesis approach of silver nanoparticles (AgNPs) using dried orange peel extract. Characterization studies revealed the synthesis of 25-30 nm AgNPs with distinct morphology as observed in transmission electron microscopes. Dynamic light scattering spectroscopy and Fourier transform infrared spectroscopy analyses further characterized nanoparticles confirming their stability and the presence of functional groups...

One of the primary causes of morbidity and mortality in those with short bowel syndrome (SBS) is sepsis, caused by bacterial translocation (BT). Since synbiotics can cease gut-related bacterial overgrowth, they may serve as a supportive dietary supplement-based strategy after gastrointestinal surgery. This study was conducted to determine the effects of Lactobacillus acidophilus and pectin on BT and gut adaptation after extensive small bowel resection in the rat. Forty rats were distributed in four groups. Group A suffered laparotomy, group B suffered gut transection and reanastomosis, SBS rats (group C) suffered 75% small gut resection, and finally, Group D suffered gut resection and treated with a synbiotic cocktail from day 7 before the surgery to day 14 after it...

Multiple Sclerosis is an inflammatory disease of the central nervous system in which T cells experience a second phase of activation, which ultimately leads to axonal demyelination and neurological disability. The recent advances in stem cell therapies may serve as potential treatments for neurological disorders. There are broad types of stem cells such as neural, embryonic, mesenchymal and hematopoietic stem cells with unprecedented hope in treating many debilitating diseases. In this paper we will review the substantial literature regarding experimental and clinical use of these stem cells and possible mechanisms in the treatment of MS...

There are considerable efforts to identify naturally occurring substances as new drugs in cancer therapy. Many components of medicinal plants have been identified that possess substantial anticancerous properties. This prompted us to investigate the effect of Scrophularia striata (an Iranian species belonging to the Scrophulariace family) extract on the growth of astrocyte cancer cell line (1321). The 1321 cell line were seeded in 96-well culture plates in the presence and absence of various concentrations of either leaf and seed filtered and unfiltered extract of Scrophularia striata to determine their probable anticancer effects in comparison with etoposide (chemical anticancer reagent)...

The aim of the present study was to achieve the immobilization of dermatan sulfate (DS) on polyethylene terephthalate (PET) surfaces and to evaluate its biocompatibility. DS obtained from the skin of Scyliorhinus canicula shark was immobilized via carbodiimide on knitted PET fabrics, modified with carboxyl groups. PET-DS characterization was performed by SEM, ATR-FTIR and contact angle measurements. Biocompatibility was evaluated by investigating plasma protein adsorption and endothelial cell proliferation, as well as by subcutaneous implantations in rats...
