Objectives: The aim of this study was to compare the levels of IL-6, IL-10, IL-17 and IL-33 in the peri-implantar crevicular fluid (PICF) and in parotid gland saliva (PGS) of healthy patients, and peri-implantitis and peri-implant mucositis patients.
Materials And Methods: The PICF was collected from 40 implants as follows: 10 peri-implant mucositis patients, 20 peri-implantitis patients and 10 healthy patients. The PICF and PGS samples collected from each patient were quantified for IL-6, IL-10, IL-17 and IL-33 by enzymatic immunosorbent assay (ELISA).
Results: IL-6, IL-17 and IL-33 levels on PIFC were significantly higher in peri-implantitis group when compared to healthy group. IL-17 and IL-33 levels in PIFC were significantly higher in peri-implant mucositis group than in healthy group. There was no significant difference when comparing IL-6, IL-10, IL-17 and IL-33 levels in PGS among healthy, peri-implant mucositis and peri-implantitis groups.
Conclusions: Therefore, as in patients with peri-implantitis there were significantly higher levels of IL-6, IL-17 and IL-33 in PICF, we believe that these cytokines were intensifying local inflammatory process, and contributing to clinical aspects such as increased marginal bleeding and probing depth found in patients with peri-implantitis. Furthermore, as IL-17 and IL-33 were increased in patients with peri-implant mucositis, hypothesized that these cytokines were also contributing to the inflammatory process observed in this disease.

Background: Birch pollen (BP) interacts with airway epithelial cells to cause allergic sensitization and allergy in predisposed individuals. However, the basic mechanisms underlying the clinical effects are poorly understood. Changes in gene expression and cytokine secretion in nasal mucosal cells upon BP exposure were determined in BP-allergic and non-allergic individuals.

Background: Circular RNAs (circRNAs) are a novel class of endogenous non-coding RNA molecules in eukaryotes, involved in many essential biological processes. However, their role in allergic rhinitis (AR) has not been extensively studied.
Methods: The expression levels of hsa_circRNA_100791 were measured using qRT-PCR in peripheral blood mononuclear cells (PBMCs) and nasal mucosa from AR patients.

Article Synopsis
- Patellar tendinopathy, or jumper's knee, is a painful condition affecting athletes, prompting a study to evaluate the effectiveness of platelet-rich plasma (PRP) treatments alone and combined with extracorporeal shockwave therapy (ESWT).
- The study involved 33 athletes randomly assigned to receive either PRP with sham treatment or PRP plus ESWT, with follow-ups over a year to assess pain reduction and functional improvements.
- Results indicated that combining PRP with ESWT led to quicker pain relief and improved outcomes without causing discomfort or injury, supporting its effectiveness for treating chronic patellar tendinopathy in athletes.

The role of innate receptors in initiating the early inflammatory response to helminth larval stages in affected tissues during their life cycle within the host remains poorly understood. Given its pivotal role in detecting microbial elements and eliciting immune responses, exploring the NOD1 receptor could offer crucial insights into immune responses to parasitic infections. By using the larval ascariasis model, the acute model for early Ascaris sp.

Objective: To investigate the effect of baijinpingchuan (, BJPC) on the asthma rat model and identify differential metabolites and disturbed metabolic pathways.
Methods: The rats were categorized into six groups: control, dexamethasone (DEX), ovalbumin (OVA), and low-, median-, and high-dose BJPC. The rats, except for the control group, were initially treated with OVA to develop the asthma model, which was then activated using DEX, OVA, and low-, median-, and high-dose BJPC.
