Exosomes in infectious diseases: insights into leishmaniasis pathogenesis, immune modulation, and therapeutic potential.

Leishmaniasis continues to be a critical international health issue due to the scarcity of efficient treatment and the development of drug tolerance. New developments in the research of extracellular vesicles (EVs), especially exosomes, have revealed novel disease management approaches. Exosomes are small vesicles that transport lipids, nucleic acids, and proteins in cell signalling.

Medications and Orthodontic Tooth Movement: What Accelerates and Diminishes Tooth Movement?

The biological aspect of orthodontic tooth movement is influenced by the magnitude and duration of the applied force. This initiates signaling cascades essential for bone remodeling, which involve activating various cell signaling pathways that enhance the metabolism of the periodontal ligament, leading to localized bone resorption and deposition. This process facilitates tooth movement on the pressure side and promotes healing on the tension side.

Skin anti-aging potential of extract: Antioxidant and enzyme inhibition activities supported by ADMET and molecular docking studies.

Aging is a natural process that occurs in all living organisms. Particularly, the skin embodies aging since it serves as a barrier between the body and its surroundings. Previously, we reported the wound healing effect of and identified compounds therein.

Assessing the Application and Effectiveness of Human Amniotic Membrane in the Management of Venous and Diabetic Ulcers: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

This study aimed to assess the efficacy of human amniotic membranes (HAM) in treating venous and diabetic ulcers, which often pose challenges in healing. A systematic review and meta-analysis were conducted, evaluating 10 relevant studies involving 633 participants. Findings revealed that HAM treatment significantly accelerated ulcer closure, demonstrating over 90% complete healing compared to standard care.

Quantitative and qualitative 3D analysis of mandibular lingual concavities: Implications for dental implant planning in the posterior mandible.

Objective: The purpose of this study is to investigate the type of ridge (degree of angulation of the lingual concavity) and the buccolingual dimensions in the area of the first and second molars in both genders of different ages and how this will affect implant placement in the posterior mandible.

Materials And Methods: This retrospective cross-sectional study comprised cone beam computed tomography images of 150 dental patients (75 males and 71 aged ≥30). The following were measured/reported: type (morphology) of the ridge (convex [C], parallel [P], or undercut [U]), buccolingual width at the base and the crest of the ridge, and ridge height.

Pediatricians' Awareness of Pediatric Psoriasis in the Makkah Region, Saudi Arabia.

Background Psoriasis is an autoimmune disease characterized by the typical appearance of red, thickened, scaly patches on the skin (plaques). These plaques can vary in size and distribution from person to person. In some individuals, it may affect small areas of skin, while in others, large areas covering their body may be involved.

Cone-Beam Computed Tomography-Based Investigation of the Prevalence and Distribution of Pulp Stones and Their Relation to Local and Systemic Factors in the Makkah Population: A Cross-Sectional Study.

Objectives This study aimed to assess the prevalence and distribution of dental pulp stones and evaluated their possible associations with local and systemic factors in the Makkah population in Saudi Arabia. Materials and methods Archived cone-beam computed tomography (CBCT) images for 390 patients, from the electronic health records (EHR) in the Dental Teaching Hospital, Umm Al-Qura University, were used. Images were examined in all planes (coronal, sagittal, and axial) for a discrete radiopaque mass in the pulp of all teeth, in both arches.

Socio-Demographics of Initial Substance Use Exposure and Its Relation to Progression: A Cross-Sectional Study in Saudi Arabia.

Introduction: Empirical evidence on substance use in Saudi Arabia is lacking. This quantitative study is aimed at describing the socio-demographics of initial exposure to substance use and its relation to substance abuse progression.

Method: A questionnaire about socio-demographics during initial exposure to substance use was completed by 379 participants.

Impact of Asthma Education Program 2020-2021 on Asthma Control Among Bronchial Asthma Children in Madinah City, Saudi Arabia.

Background: Asthma control among asthmatic children still remains suboptimal. Saudi literature are scarce in this context, and there is a paucity of reports that compare asthma control level pre- and post-education program directed to asthmatic patients and their parents.

Objectives: The objective of this study was to assess the impact of asthma education and flu vaccination on asthma control in asthmatic children in Madinah region from 2020 to 2021, in terms of ED visits, hospitalization, pediatric intensive care unit (PICU) admission, and asthma control level.

The Antifungal Efficacy of Pure Garlic, Onion, and Lemon Extracts Against Candida albicans.

Introduction: The oral cavity is considered to be one of the most intricate environments in the human body. It is known to harbor commensal microorganisms that do not cause diseases, such as , a yeast fungus that has a carriage rate that tends to increase with age. It is worth noting that  can be readily identified within the flora of the gastrointestinal tract in 80% of healthy patients.

Hyaluronic Acid: A New Approach for the Treatment of Gingival Recession-A Systematic Review.

This systematic review aimed to investigate the effectiveness of hyaluronic acid (HA) on the clinical treatment outcomes of patients with gingival recession. A systematic search was performed in PubMed, Cochrane Central Register of Controlled Trials, Embase, Scopus, and Google Scholar for studies up to 15 August 2022. Two reviewers separately selected the papers for eligibility after conducting a thorough search.

Effect of Luting Cement Film Thickness on the Pull-Out Bond Strength of Endodontic Post Systems.

Optimal bond strength between the prefabricated post/dowel to the surrounding dentin is essential. The present study aimed to analyze and compare the effect of three different cement film thicknesses on the pull-out bond strength of three different prefabricated post systems. Extracted natural teeth (N = 90) with similar root dimensions were acquired.
