ZnSnO@SiO@5-FU Nanoparticles as an Additive for Maxillary Bone Defects.

This study investigates the synthesis of ZnSnO@SiO@5-FU nanoparticles as an additive for bone fillers in dental maxillofacial reconstruction. ZnSnO nanoparticles were synthesized and coated with a SiO shell, followed by the incorporation of 5-Fluorouracil (5-FU), aimed at enhancing the therapeutic properties of classical fillers. Structural analysis using X-ray diffraction confirmed that ZnSnO was the single crystalline phase present, with its crystallinity preserved after both SiO coating and 5-FU incorporation.

Development of three biofuel CRMs for the quality parameters in biodiesel and wood pellet via a joint research project.

Biomass is a key element in biofuels which can be defined as a fuel produced through contemporary biological processes, and its increased use can support the EU's aims of reducing greenhouse gas emissions.

The purpose of this study is to evaluate the MRI semiology of the endometrial carcinomas that mimic benign lesions, the main factors that may affect the correct diagnosis and the feasibility of magnetic resonance imaging to evaluate the depth of the myometrial invasion of endometrial cancer.

The Use and Potential Benefits of N-Acetylcysteine in Non-Acetaminophen Acute Liver Failure: An Etiology-Based Review.

Acute liver failure represents a life-threatening organ dysfunction with high mortality rates and an urgent need for liver transplantation. The etiology of the disease varies widely depending on various socio-economic factors and is represented mainly by paracetamol overdose and other drug-induced forms of liver dysfunction in the developed world and by viral hepatitis and mushroom poisoning in less developed countries. Current medical care constitutes either specific antidotes or supportive measures to ensure spontaneous recovery.

The responses of alfalfa sprouts to CH and NH may fluctuate, depending on tissue sensitivity and the phase of plant development.

Kinematics of the viscous filament during the droplet breakup in air.

The dripping regime in the vicinity of the fluid droplet breakup is analyzed using the correlation between experiments and numerics. The evolutions of filament's neck and its corresponding thinning velocity are described using the logistic functions. Three flow regions are observed as the relative time decreases: (1) a monotonous increase of the neck's thinning velocity, where inertia and capillarity are balanced, (2) a transition domain characterized by the equilibrium between inertia, capillarity, and viscous forces, where the thinning velocity varies non-monotonically with the relative time and (3) the final droplet pinch-off, where velocity decreases or oscillates around a constant value.

Lung neuroendocrine tumors: A systematic literature review (Review).

Neuroendocrine tumors (NETs) can have multiple localizations in the human body however, most often, it appears in the in thorax at tracheobronchial tree and the thymus. NETs are a group of tumors with heterogenous malignancy that evolve from neuroendocrine cells, with the lung being the second target organ after the gastrointestinal tract. These rare tumors are usually asymptomatic and non-functional with little information regarding incidence in the specialty literature.

Antimicrobial Activity and Degradation Ability Study on Nanoparticle-Enriched Formulations Specially Designed for the Neutralization of Real and Simulated Biological and Chemical Warfare Agents.

The present work reveals a comprehensive decontamination study on real and simulated biological and chemical warfare agents (BCWA). The emphasis was on evaluating the antimicrobial activity against real biological warfare agents, such as , and also the capacity of neutralizing real chemical warfare agents, such as mustard gas or soman, by employing three different types of organic solutions enriched with ZnO, TiO, and zeolite nanoparticles, specially designed for decontamination applications. The capacity of decontaminating BCWA was evaluated through specific investigation tools, including surface monitoring with the swabs method, minimum inhibitory (MIC) and minimum bactericidal concentration (MBC) evaluations, time-kill tests for microorganisms, and GC-MS for monitoring chemical agents on different types of surfaces (glass, painted metal, rubber, and cotton butyl rubber).

Reactive Organic Suspensions Comprising ZnO, TiO, and Zeolite Nanosized Adsorbents: Evaluation of Decontamination Efficiency on Soman and Sulfur Mustard.

This paper comprises an extensive study on the evaluation of decontamination efficiency of three types of reactive organic suspensions (based on nanosized adsorbents) on two real chemical warfare agents: soman (GD) and sulfur mustard (HD). Three types of nanoparticles (ZnO, TiO, and zeolite) were employed in the decontamination formulations, for enhancing the degradation of the toxic agents. The efficacy of each decontamination solution was investigated by means of GC-MS analysis, considering the initial concentration of toxic agent and the residual toxic concentration, measured at different time intervals, until the completion of the decontamination process.

Experimental Investigation on Water Adsorption Using Laser Photoacoustic Spectroscopy and Numerical Simulations.

In the present research we propose a model to assess the water vapors adsorption capacity of a SiO trap in the breathing circuit, aiming to reduce the loading of interfering compounds in human breath samples.

Indigenizing our research: indigenous community leadership in HIV epidemiology research.

The use of data intensive health research has allowed for greater understandings of population health. When conducting data intensive health research, engaging and involving the community is essential for conducting meaningful research that is responsive to the public's needs. Particularly, when engaging Indigenous communities in research, there is a need to understand historical and ongoing impacts of colonialism and recognize the strengths in Indigenous Peoples' knowledges and experiences while supporting Indigenous leadership and self-determination in research.
