The pretreatment of pulp with enzymes has been extensively studied in the laboratory. However, due to cost constraints, the application of enzymes in the pulp and paper industry is very limited. In this paper, an environment-friendly and efficient pulping method is proposed as an alternative to traditional pulping and papermaking methods. This new method overcomes the low efficiency and extreme pollution problems associated with traditional pulping methods. In addition, fitting equations for the new pulping method are constructed using data on enzyme treatments, which reflect the effect of enzymes and enable the realization of real-time control of the pulping process. The experimental results show that the efficiency of the pulping and papermaking process can be improved using biological enzymes, and the separation of cellulose can be facilitated using mixed enzymes, which have a better effect than single enzymes.

Introduction: Accurate diagnosis of pulpal health is crucial to identify the most effective therapeutic approach. However, differentiating pulpal conditions, which may require different treatment approaches, remains a challenge. This study aimed to address this gap by investigating the protein levels of 17 inflammatory biomarkers simultaneously in the dental pulp with different clinical diagnoses.

Introduction: Pulse oximetry exhibits great potential for use in endodontic diagnosis as an effective method to assess pulp vitality. Cell phone-integrated oximeters represent an emerging alternative that may offer greater accessibility. This study aimed to investigate the relation between pulp oxygenation rates (%SpO) and clinical diagnosis of healthy pulp (HP), reversible pulpitis (RP), symptomatic irreversible pulpitis (IP), or pulp necrosis (PN), comparing two pulse oximeters (conventional and mobile-connected).

Although platelet-rich plasma (PRP) has demonstrated considerable regenerative potential in regenerative endodontic treatment, its clinical efficacy may be limited by the rapid degradation of its bioactive components, leading to inconsistent outcomes. To overcome this challenge, the present study explores the use of nano-sized exosomes derived from PRP-a novel designated as PRP exosomes (PRP-Exo)-as a more stable and targeted biomolecular delivery system to promote odontogenic differentiation within the dentin-pulp complex. The primary objective is to investigate the expression of key odontogenic markers, transforming growth factor-β1 (TGF-β1) and Dentin Sialophosphoprotein (DSPP), in human dental pulp stem cells (hDPSCs) following PRP-Exo treatment.

Introduction: Rhinovirus (RV) is the leading cause of exacerbations of lung disease. A sensory neuronal model, derived from human dental pulp stem cells and differentiated into peripheral neuronal equivalents (PNEs), was used to examine RV's effects on airway sensory nerves. We investigated whether RV can directly infect and alter PNEs or whether it exerts effects indirectly via the release of mediators from infected epithelial cells.
