Therefore, the detection and treatment of CSCs are the most important factors in overcoming CRC. Materials & methods Herein, we developed a magnetite-based nanomedicine (superparamagnetic iron oxide@poly(sodium styrene sulfonate)/irinotecan/human serum albumin-anti-CD133 nanoparticle) using loco-regional hyperthermia combined with chemotherapy for CRC- and CSC-specific targeting treatment. Results The designed nanoparticles were highly biocompatible and exhibited a higher temperature increase rate under radiofrequency generator irradiation. The nanoparticles could be used as a T2-weighted magnetic resonance imaging contrast media, and also applied during hyperthermia and chemotherapy to display a synergistic anticancer effect. Conclusion Therefore, the superparamagnetic iron oxide@poly(sodium styrene sulfonate)/irinotecan/human serum albumin-anti-CD133 nanoparticles are a powerful candidate for future antitumor strategies.In recent years, nanogels have emerged as promising drug delivery vehicles; their ability in holding active molecules, macromolecules and drugs, together with the capability to respond to external stimuli, makes them a suitable tool for a wide range of applications. These features allow nanogels to be exploited against many challenges of nanomedicine associated with different kinds of pathologies which require the use of specific drug delivery systems. In this review our aim is to give the reader an overview of the diseases that can be treated with nanogels as drug delivery systems, such as cancer, CNS disorders, cardiovascular diseases, wound healing and other diseases of human body. For all of these pathologies, biological in vivo assays can be found in the literature and in this work. We focus on the peculiarities of these nanogels, highlighting their features and their advantages in respect to conventional treatments.Objective To optimize photobiomodulation therapy (PBMT) for spinal cord injury (SCI) by studying the effect(s) of irradiation parameters and position of PBMT on injury site using Monte Carlo simulation and a three-dimensional voxelated SCI rat phantom model. Background Several studies used a range of irradiation parameters and surface irradiances to calculate the fluence delivered to the SCI site. However, most have ignored factors such as the optical properties of tissues, irradiation parameters, and position. Therefore, although such studies present a broad range of treatment outcomes, a comparison of the treatment efficacy concerning the applied fluence using these studies presents certain challenges Methods In this study, an 810 nm top-hat beam was simulated for 5 numerical apertures (NAs; 0.0, 0.2, 0.4, 0.6, and 0.8), 10 beam radii (0.001, 0.01, 0.1, 0.25, 0.5, 1, 2.5, 5, 10, and 25 mm), and 17 different irradiation positions relative to the SCI site. Results The beam radius and position strongly affect the accumulated fluence within the injury site, whereas the NA appears to have a smaller effect on the accumulated fluence within the injury site. A large probe beam produces a uniform fluence distribution reaching the injury site, minimizing the effect of misplacing the probe at the center of the injury. Conclusions Our findings will be beneficial to understanding the effects of irradiation parameters on tissues and organs, which will help reduce variability in the fluence applied to injury sites and will help optimize PBMT outcomes.Vitamin B12, a water-soluble vitamin, plays a vital role in the formation of hematopoietic stem cells and has been associated with oral mucosal diseases, mainly recurrent aphthous stomatitis (RAS). The latter is a debilitating condition, and B12 was proposed as a potential treatment given its role in regenerating oral mucosal tissue. There is conflicting evidence that B12 deficiency causes RAS. Five of the seven randomized controlled trials reviewed used the inactive form of B12 (cyanocobalamin) as intervention, while the other two used the active form (methylcobalamin). Of the latter two, buccal discs (500 μg B12) showed significant improvement and reduced perceived pain in 77% of the subjects, and submucosal injections showed a significant difference in pain, starting from the second day. see more Moreover, three studies administered vitamin B12 sublingually with different dosages, which revealed that the higher dose (1000 μg) achieved a significant reduction in outbreaks, number, and duration of ulcers, especially after six months. Multivitamins showed no difference in new RAS episodes and duration. Injectable B12 was compared with the oral form, and nearly 50% of the injection group reported a desired response by the eighth week. An ointment form (500 μg) showed a significant reduction in pain levels after two days of treatment. Based on the available literature, we suggest that a daily dose of 1000 μg of vitamin B12 sublingually for six months can be used to treat RAS. Nevertheless, this conclusion should be considered tentative due to the lack of high quality, large scale studies.
This survey study evaluates current management strategies for venous ulceration and the impacts of the EVRA trial results.

An online survey was disseminated to approximately 15000 clinicians, through 12 vascular societies in 2018. Survey themes included referral times, treatment times and strategies, knowledge of the EVRA trial and service barriers to managing venous ulceration. Data analysis was performed using Microsoft Excel and SPSS.

664 responses were received from 78 countries. Respondents were predominantly European (55%) and North American (23%) vascular surgeons (74%). Responses varied between different countries. The median vascular clinic referral time was 6 weeks and time to be seen in clinic was 2 weeks. This was significantly higher in the UK (p ≤ 0.02). 77% of respondents performed surgical/endovenous interventions prior to ulcer healing, the median time to intervention was 4 weeks. 31% of participants changed their practice following EVRA. Frequently encountered barriers to implementing change were a lack of operating space/time (18%).
