Optimizations of Placenta Extracellular Matrix-Loaded Silk Fibroin/Alginate 3D-Printed Scaffolds Structurally and Functionally for Bone Tissue Engineering.

Recent interest has been focused on extracellular matrix (ECM)-based scaffolds totreat critical-sized bone injuries. In this study, urea was used to decellularize and solubilize human placenta tissue. Then, different concentrations of ECM were composited with 8% alginate (Alg) and 12% silk fibroin (SF) for printing in order to produce a natural 3D construct that resembled bone tissue.

Unexpected multiple sclerosis-like symptoms in a rheumatoid arthritis patient treated with Etanercept: A case report.

Key Clinical Massage: Although tumor necrosis factor (TNF) inhibitors are used to prevent autoimmune disease, but they can cause adverse effects. Multiple sclerosis syndrome is one of the rare complications following treatment with TNF inhibitor. We reported a case of rheumatoid arthritis with unfavorable outcome post Etanerecept therapy.

Preliminary report of Iranian Registry of Alzheimer's disease in Tehran province: A cross-sectional study in Iran.

Background And Aims: Alzheimer's disease (AD) is the main cause of dementia and over the 55 million people live with dementia worldwide. We aimed to establish the first database called the Iranian Alzheimer's Disease Registry to create a powerful source for future research in the country. In this report, the design and early results of the Iranian Alzheimer's Disease Registry will be described.

Cerebral venous sinus thrombosis following intracerebral hemorrhage after COVID-19 AstraZeneca vaccination: A case report.

The patient was a 55-year-old female patient who presented with sudden onset of left hemiplegia, facial hemiparesis, and hypoesthesia. She has received her first dose of the AstraZeneca COVID-19 vaccine. This case indicates that vaccination may raise the hypercoagulable state even in a condition of post-ICH and anticoagulant prophylaxis.

IgG4-related disease associated with the primary manifestation of recurrent cerebral venous thrombosis: A rare case report.

Nervous system involvement in IgG4-related systemic disease (IgG4-RD) is rarely reported and manifests as hypertrophic pachymeningitis and hypophysitis. In this report, a 33-year-old woman with neurological manifestations was diagnosed with IgG4-RD by biopsy. The patient showed improvement in symptoms after treatment.

Acute polyneuropathy as the main manifestation of primary Sjogren's syndrome: A case report.

Sjogren's syndrome is an inflammatory disease affecting many systems. We report a Sjogren case with the presenting feature of an acute motor-predominant polyneuropathy resembling Guillain-Barre syndrome. Upon further investigation, it was found that the patient had sicca symptoms for months.
