Prevalence of accessory mental foramen and lateral lingual foramen using cone beam computed tomography: A single-center cross-sectional study.

Purpose: This study aimed to assess the prevalence, dimensions, and positions of accessory mental foramen (AMF) and lateral lingual foramen (LLF) in an Iranian population using cone beam computed tomography (CBCT).

Methods And Materials: In this cross-sectional study, CBCT images of 2082 patients were retrospectively reviewed based on inclusion criteria, including images from the mandibular region taken in the past five years with accurate demographic data. Exclusion criteria included images with significant pathologies, fractures, or poor quality.

The mitochondrial calcium signaling, regulation, and cellular functions: A novel target for therapeutic medicine in neurological disorders.

Mitochondrial calcium (Ca ) dynamics play critical roles in regulating vital physiological conditions in the brain. Importantly, Mitochondria-associated endoplasmic reticulum (ER) membranes serve different cellular functions including Ca signaling, bioenergetics, phospholipid biosynthesis, cholesterol esterification, programmed cell death, and communication between the two organelles. Several Ca -transport systems specialize at the mitochondria, ER, and their contact sites that provide tight control of mitochondrial Ca signaling at the molecular level.

Fetal Hypothyroidism Impairs Aortic Vasorelaxation Responses in Adulthood: Involvement of Hydrogen Sulfide and Nitric Oxide Cross talk.

Thyroid hormones have a wide range of effects on growth, differentiation, evolution, metabolism, and physiological function of all tissues, including the vascular bed. In this study, the effect of fetal hypothyroidism on impairment of aortic vasorelaxation responses in adulthood was investigated with emphasis on possible involvement of hydrogen sulfide (H2S)/nitric oxide interaction. Two groups of female rats were selected.

The Effect of Immediate Versus Delayed Addition of the Nasal Stent to the Nasoalveolar Molding Plate on Nostrils Shape and Cleft Width in Infants With Unilateral Cleft Lip and Palate.

Objective: The main aim of this study was to evaluate the effect of immediate versus delayed addition of the nasal stent to the nasoalveolar molding plate on the nose shape and alveolar cleft area in unilateral cleft lip and palate infants.

Method: Twenty nonsyndromic newborn infants with unilateral cleft lip and palate were scanned 3 dimensionally using Proface software. In the experimental group, the nasal stent was added on the day the molding plate arrived, and in the control group when the alveolar gap reached 5 mm.
