Distribution, Source, and Contamination of Heavy Metals in Coastal Sediments of Jeddah, Red Sea, Saudi Arabia.

The study investigates heavy metal (HM) contamination in coastal sediments of Jeddah along Red Sea coast, analyzing spatial distribution and sources. 24 samples underwent (ICP-AES) for Fe, Al, Mn, Ni, Pb, Zn, Cu, Cr, Co, Sr, V, and As. HM averages followed Fe ˃ Al ˃ Sr ˃ Mn ˃ Zn ˃ V ˃ Cu ˃ Ni ˃ Cr ˃ As ˃ Co ˃ Pb.

Effectiveness of tranexamic acid in orthognathic surgery: A systematic review of systematic reviews.

Purpose: This study aimed to review the currently available evidence on the effectiveness of administering tranexamic acid (TXA) to patients undergoing orthognathic surgery.

Methods: A study protocol was developed in accordance with the Preferred Reporting Guideline for Overviews of Reviews (PRIOR) and registered on the International Prospective Register of Systematic Reviews (PROSPERO) under Registration No. CRD42021232931.

Cervical Spine Injuries and Maxillofacial Trauma: A Systematic Review.

Objectives: Identify specific maxillofacial trauma patterns associated with cervical spine injuries.

Methods: The protocol was developed according to (PRISMA-P) and was admitted to PROSPERO under accreditation code #CRD42020177816. Furthermore, the reporting of the present SR was conducted based on the PRISMA checklist.

The neurosensory deficit of inferior alveolar nerve following bilateral sagittal split osteotomy: a prospective study.

Objectives: Investigation in Saudi Arabia or the Arab Gulf States to assess the unfavorable impacts of the bilateral sagittal split osteotomy (BSSO) is non-existent, so questions have been raised about the success rate of this operation and the frequency of unwilling outcome. To address these worries, we directed a case series study to evaluate the hypoesthesia, a type of neurosensory deficit (NSD) of the inferior alveolar nerve (IAN) after BSSO, and if the hypoesthesia outcome will improve if the surgeries performed by a single surgeon.

Patients And Methods: This was a prospective case series study for the patient who underwent BSSO in a medical complex that is considered one of the largest in Saudi Arabia (Riyadh).

Indirect Somatic Embryogenesis from Mature Inflorescence Explants of Date Palm.

Due to the limitations associated with shoot tip explants in the micropropagation of date palm, inflorescence explants are an ideal alternative. This chapter focuses on the protocol for the induction of callus from inflorescence tissue, establishment for proliferation of somatic embryos, germination, elongation, rooting, and acclimatization. Female inflorescences, 30-40 cm in length, cv.
