Two new sesquiterpene glucosides, 1,6,9-trihydroxy-eudesm-4(15)-en-1,6---diglucopyranoside () and 1,6,9-trihydroxy-eudesm-3-en-1,6---diglucopyranoside () were obtained along with the 1α,6,9-trihydroxy-5,10-bis-epi-eudesm-3-en-6---D-glucopyranoside , chlorogenic acid , luteolin 7--rutinoside and luteolin 7-- glucoside from the whole plant parts of . Their structures were determined on the basis of 1 D, 2 D NMR and HRMS analyses. The cytotoxic activity of compounds against human lung cancer cells (A549) and normal human lung cells (BEAS-2B) was determined using the MTT colorimetric assay.

Background: H syndrome is a rare genodermatosis deriving from a mutation in the SLC29A3 gene and affecting numerous systems, particularly the skin. The syndrome exhibits different clinical characteristics involving several systems, most beginning with the letter "H." The most common clinical findings are cutaneous hyperpigmentation, flexion contracture in the fingers, hearing loss, short stature, insulin-dependent diabetes mellitus, heart anomalies, hepatosplenomegaly, and hypogonadism.

Objective: Nutrition and exposure to various chemicals, including environmental pollution, insecticides, and plant phytoestrogens (having oestrogen-like effects), are environmental factors that affect puberty onset. The aim of this study was to identify the effects of propolis, which has been reported to have oestrogenic effects, on precocious puberty and the reproductive system in prepubertal female rats (ovary, endometrium, breast).

Methods: Thirty-four 25-day-old, prepubertal, female Sprague-Dawley rats were included.

Objectives: Type 1 diabetes mellitus (T1DM), a chronic autoimmune disease characterized by insulin deficiency, is related to periodontal diseases in children and adolescents. Our aim was to profile salivary human beta-defensin (hBD)-2 and hBD-3 concentrations in relation to periodontal and T1DM status in children and adolescent populations.

Material And Methods: Unstimulated saliva samples were collected from 66 participants including periodontally healthy T1DM patients (T1DM + C; n = 18), T1DM patients with gingivitis (T1DM + G; n = 20), systemically and periodontally healthy individuals (SH + C: n = 15), and systemically healthy gingivitis patients (SH + G; n = 13).

Background: Positive end-expiratory pressure (PEEP) can overcome respiratory changes that occur during pneumoperitoneum application in laparoscopic procedures, but it can also increase intracranial pressure. We investigated PEEP vs. no PEEP application on ultrasound measurement of optic nerve sheath diameter (indirect measure of increased intracranial pressure) in laparoscopic cholecystectomy.

Article Synopsis
  • The study aimed to compare two techniques for inserting the i-gel, a supraglottic airway device, focusing on insertion time and first-attempt success rates.
  • Patients were divided into two groups: one used the standard placement method, while the other employed the triple airway maneuver (head tilt, jaw thrust, and open mouth).
  • Results showed that the triple maneuver resulted in significantly quicker insertion times (20 seconds vs. 32 seconds) and a slightly higher first-attempt success rate, suggesting it's a better option for i-gel insertion.
