Preparation and characterization of pH-sensitive chitosan/starch/MoS nanocomposite for control release of curcumin macromolecules drug delivery; application in the breast cancer treatment.

In this work, chitosan (CS), Starch (S), and Molybdenum Disulfide (MoS) were combined to create a nanocarrier that was utilized to treat breast cancer using the MCF-7 cell line. To analyze the features of the nanocarrier, Fourier-transform infrared spectroscopy (FTIR) and X-Ray diffraction (XRD) tests were performed, respectively, to discover physical interactions and chemical bonding. Field emission scanning electron microscopy (FE-SEM), Dynamic light scattering (DLS), and zeta potential analyses were performed and reported to determine the structural characteristics and morphology of nanoparticles, size distribution, and surface charge of nanocarriers, respectively.

Surgical Treatment Options for Buerger's Disease (Experience with 315 Cases in Iran).

Buerger's disease (thromboangiitis obliterans) may be a rare peripheral vascular disease that sometimes affects young male smokers. This study presents surgical treatment options for 315 Buerger's patients during a period of 18 years from 2002 to 2020. In this cross-sectional study, 315 newly diagnosed Buerger patients in a period of 18 years (by Census sampling) were evaluated.

ESR, CRP, and failure of Arterio-Venous Fistula (AVF).

The survival of arteriovenous fistula (AVF) remains an important problem for hemodialysis patients, accounting for 20% of all hospitalizations related to AV access problems in western countries. We designed an observational prospective cohort study on 265 AVFs and evaluated their results after 4 months of fistula creation and its relation to laboratory tests as ESR and CRP levels. Wrist or antecubital AVFs were created for patients with End-Stage renal disease.

Surgical Repair Outcomes of Inflammatory and Degenerative Abdominal Aortic Aneurysms.

Inflammatory abdominal aortic aneurysm (IAAA) is characterised by thick aortic wall, with perianeurysmal fibrosis extending to adjacent organs. This study aimed to determine the early surgical outcomes of 10 IAAAs and compare the risk factors, perioperative complications, and 30-day mortality of these patients to 50 degenerative AAAs (dAAA), who underwent open repair in Sina Hospital, Tehran, Iran. The study was conducted from 2011 to 2019.

Endovascular treatment of penetrating vascular injuries.

Endovascular treatment of vascular injuries has resulted in reduced operating time, blood loss, hospital mortality and sepsis. The purpose of this study was to evaluate the success and complication rate of the endovascular management of penetrating peripheral vascular injuries during 5 years. In this observational study, the clinical records and imaging features of 22 penetrating trauma injuries of 276 penetrating vascular trauma patients (8%), which were repaired using endovascular stent-grafts or coil embolization, between April 2013 and August 2018, included in the study.

Behcet's disease and multiple arterial aneurysms: 4 case reports.

Behcet's disease (BD) is a vasculitis of unknown origin. BD is rare in Western countries and the southern hemisphere and is mainly seen in countries along the Silk Road such as the Middle East and Mediterranean regions including Iran. We report four interesting cases of BD with multiple aneurysms three of which had subclavian aneurysms.

Totally implanted chemotherapy port catheters: literature review and report of four cases.

Totally implantable catheters tend to be the most popular choice because once installed they allow permanent access to a deep vein, which is gained by puncturing the port rather than a vein. In this article, we explain four cases of chemotherapy port complications: superior vena cava (SVC) syndrome in a metastatic colorectal cancer patient who presented with bilateral mastitis, snare technique for removal of migrated catheter line, carotid artery placement of a port in a 5-year-old child that was referred to our hospital from a pediatric center and adhesive port tip in the heart that finally we left the port . In SVC syndrome, treatment should be guided by the severity of symptoms, etiology of the obstruction, prognosis of the patient and treatment goals.

Splenic artery aneurysm, case series of seven patients.

Splenic artery aneurysms (SAA) account for 46-60% of all visceral artery aneurysms. Small SAAs are usually asymptomatic, but giant aneurysms are more likely to cause symptoms and can result in life-threatening complications. Treatment of a splenic artery aneurysms includes laparotomy, laparoscopy or endovascular techniques.

Transcranial sonography in carriers of Gaucher disease.

Glucocerebrosidase (GBA) mutation is the most common genetic risk factor in Parkinson's disease (PD). Transcranial sonography (TCS) shows increased substantia nigra (SN) echogenicity in both idiopathic and genetic forms of PD. The goal of this study was to compare maximal area of SN hyperechogenicity (aSNmax) and diameter of third ventricle (DTV) between GBA mutation carriers and healthy controls.

Early-Onset Multiple Sclerosis: Reports of 300 Patients from Iran.

Background: The epidemiologic data on demographic features of early-onset multiple sclerosis (EOMS) are rare in the Middle East, and no previous study has explored it. We aim to perform a neuroepidemiologic analysis to emphasize on the demographic features of EOMS in Tehran, Iran, during 2005-2015.

Materials And Methods: Our study was performed in Tehran, Iran; the research included patients with EOMS who had experienced their first symptoms before the age of 18 years and those who were referred to Iranian Multiple Sclerosis Society in Tehran during 2005-2015.

Correlation between CRP and early failure of arteriovenous fistula (AVF).

Background: Arteriovenous Fistula (AVF) is the ideal method of vascular access for patients on maintenance hemodialysis (HD). Therefore it is an important part of treatment in HD. There are several observations that indicate the role of inflammation in failure of AVF.
