Adipose tissue regulates metabolic balance, but aging disrupts it, shifting fat from insulin-sensitive subcutaneous to insulin-resistant visceral depots, impacting overall metabolic health. Adipose-derived stem cells (ASCs) are crucial for tissue regeneration, but aging diminishes their stemness and regeneration potential. Our findings reveal that aging is associated with a decrease in subcutaneous adipose tissue mass and an increase in the visceral fat depots mass.

Study Design: A Systematic Review OBJECTIVES: To determine the therapeutic efficacy of in vivo reprogramming of astrocytes into neuronal-like cells in animal models of spinal cord injury (SCI).

Methods: PRISMA 2020 guidelines were utilized, and search engines Medline, Web of Science, Scopus, and Embase until June 2023 were used. Studies that examined the effects of converting astrocytes into neuron-like cells with any vector in all animal models were included, while conversion from other cells except for spinal astrocytes, chemical mechanisms to provide SCI models, brain injury population, and conversion without in-vivo experience were excluded.

Background: Radiation therapy often leads to late radiation-induced skin fibrosis (RISF), causing movement impairment and discomfort. We conducted a comprehensive study to assess the effectiveness of metformin and adipose-derived stem cells (ASCs), whether autologous or allogeneic, individually or in combination therapy, in mitigating RISF.

Methods: Using a female C57BL/6J mouse model subjected to hind limb irradiation as a representative RISF model, we evaluated metformin, ASCs, or their combination in two contexts: prophylactic (started on day 1 post-irradiation) and therapeutic (initiated on day 14 post-irradiation, coinciding with fibrosis symptoms).

Despite being relatively rare, pediatric traumatic spinal cord injury (TSCI) is a debilitating event with high morbidity and long-term damage and dependency. This study aims to provide insight on the epidemiological characteristics of pediatric TSCI worldwide. The studies were included if they provided data for the pediatric population with the diagnosis of TSCI.

Article Synopsis
  • Burn injuries represent a serious global health issue that can lead to significant complications and require effective treatment options due to their potential for delayed healing and scarring.
  • Regenerative medicine, particularly the use of adipose-derived stem cells (ASCs), shows promise for improving burn wound healing and reducing scar formation, as demonstrated in various in vitro and preclinical studies.
  • Future applications of ASCs in clinical settings must overcome challenges such as variability in donor cells, and safety and efficacy concerns to ensure successful treatment outcomes.

Radiation therapy can lead to late radiation-induced skin fibrosis (RISF), causing movement restriction, pain, and organ dysfunction. This study evaluated adipose-derived extracellular matrix (Ad-ECM) as a mitigator of RISF. Female C57BL/6J mice that were irradiated developed fibrosis, which was mitigated by a single local Ad-ECM injection, improving limb movement and reducing epithelium thickness and collagen deposition.

Introduction: We aimed to evaluate the effectiveness and safety of radiofrequency ablation (RFA) for non-surgical treatment of locally recurrent thyroid cancers, in both well-differentiated and medullary thyroid carcinomas (DTC and MTC) that are not amenable to traditional treatments.

Methods: We conducted a retrospective review of 48 patients with 103 recurrent tumors (81 DTC, 22 MTC) who underwent ultrasound-guided RFA. Patients were followed for 12-37 months to observe the outcomes and complications.

Introduction: Zygomatic fractures are usually accompanied with neural complications, which are routinely treated by surgery or medication. However, photobiomodulation has been proven as a non-invasive method with better results in nerve's regeneration and repair. Therefore, in this study, we aimed to investigate the healing effect of photobiomodulation on neurosensory defect after facial trauma.

PEX11β ([OMIM] 614920) mutation causes an extremely rare subgroup of peroxisomal biogenesis disorders, with only six cases reported to date. In this article, we reported a patient with episodic migraine-like attacks, delirium, mood and behavior change, polyneuropathy, and history of congenital cataract. Whole exome sequencing showed novel c.

To determine levels of change in risk factors for cardiovascular disease among people with and without a previous diagnosis of diabetes from 2007 to 2016 in Iran. Data were obtained from five rounds of the World Health Organization STEPwise approach to Surveillance (STEPS) cross-sectional surveys. Participants were 7665 and 93,733 adults with and without known diabetes, respectively, aged 25-65 years.

Article Synopsis
  • Ghosal hematodiaphyseal dysplasia (GHDD) is a rare genetic disorder characterized by anemia that responds to steroids and skeletal abnormalities in the long bones.
  • A case study describes a 3-year-old Iranian girl with severe anemia, an enlarged spleen, and X-ray evidence of bone abnormalities.
  • The girl's diagnosis was confirmed through clinical evaluation and X-rays, and she showed significant improvement after treatment with oral prednisolone.

Article Synopsis
  • The study investigates the unclear cause of Bisphosphonate-related osteonecrosis of the jaw (BRONJ) by determining whether the oral mucosa or alveolar bone is the initial site for its development.
  • Sixty male Wistar rats were used, with half receiving the drug zoledronate and the other half receiving saline, and they were monitored for signs of bone exposure and necrosis after dental extractions.
  • Results showed that injuries to the alveolar bone significantly increased the frequency of bone exposure and necrosis compared to injuries to the oral mucosa, suggesting that alveolar bone damage is a stronger trigger for BRONJ.

Objective: Previously published animal investigations on bisphosphonate-related osteonecrosis of the jaws (BRONJ) showed a variety of methods for BRONJ induction and inconsistent findings. The aim of present study was to develop a reliable protocol for BRONJ induction in rat animal model.

Subjects And Methods: In a pilot study, 64 rats were randomly divided into 4 groups and 16 subgroups (each containing 2 experimental and 2 control rats) based on the timing of tooth extraction and euthanasia.

Introduction: Third molar development, in comparison to other teeth in the dentition, has the greatest variation in morphology, anatomical position, and time of development and eruption, and its reliability for chronological age estimation is controversial. The aim of the present study was to evaluate third molar development and its relation to chronological age using panoramic radiography.

Material And Methods: A total of 2536 digital panoramic radiographs of individuals aged between 5 and 26 years were selected.
