Primary aortoduodenal fistula: As a first presentation of brucellosis; a case report.

Introduction: The etiologies of primary aortoenteric fistula include aneurysm (most common), foreign body, tumor, radiation therapy, and infection (e.g., tuberculosis, syphilis).

Effect of rare-earth oxide (EuO) on the physical, mechanical, acoustic and radiation shielding properties of the CaO-GdO-SiO-BO glasses.

In this study, we examined the effectiveness of europium-doped calcium gadolinium silicoborate glasses for determining their physical, mechanical, acoustic and radiation shielding properties with compositions of 25GdO-10CaO-10SiO-xEuO -(55-x) BO (where, x is 0.1, 0.2, 0.

A Review on Role of Inflammation in Coronavirus Disease.

The respiratory illness known as COVID-19 is caused by the novel coronavirus, SARS-CoV-2. While the precise pathogenic mechanism of COVID-19 remains unclear, the occurrence of a cytokine storm subsequent to viral infection plays a pivotal role in the initiation and advancement of the disease. The infection of SARS-CoV-2 induces a state of immune system hyperactivity, leading to an excessive production of inflammatory cytokines.

The Important Role of Interleukin-2 in COVID-19.

There is controversial literature about the effects of the interleukin-2 (IL-2) cytokine family in COVID-19 pathogenesis and immunity. So we aimed to identify the potential in the role of the IL-2 family in COVID-19. A narrative review search was done through online databases, including PubMed, Scopus, and Web of Science.

Sudden sensorineural hearing loss after receiving an inactivated viral vaccine, Sinopharm: Two-case report.

The prevalence of Coronavirus Disease 2019 is a global threat. Due to the high mortality rate caused by this disease, the vaccination is mandatory to protect patients against it and reduce the mortality. Rapid development and widespread use of vaccines have raised the possibility of adverse side effects over the course of administration and follow-up.

The use of metformin, sulfonylurea compounds and insulin and the risk of hip fractures in diabetic patients: a systematic review and meta-analysis of observational studies.

Background: Hip fracture is a major health problem that occurs more often in the elderly, especially in diabetic patients. Some studies have been conducted regarding the effect of anti- diabetic drugs on fractures. But so far, no meta-analysis study has been conducted to investigate the effect of diabetic drugs on hip fractures.

Primary isolated extraluminal hydatid cyst of left pulmonary artery.

Introduction And Importance: Hydatid cyst of the pulmonary artery is scarce. There were few reports of intramural involvement of pulmonary artery secondary to cardiac or lung hydatic cyst in the literature. To our knowledge, there was no report of a primary isolated extraluminal hydatid cyst of the left pulmonary artery.

Potentially fatal atrium perforation due to right jugular vein catheterization recognized by venography: A case report.

Central venous catheters are the prevalent path for dialysis. Our case was a 54-years-old male with a new case of end-stage renal disease with a complaint of right jugular hemodialysis catheter dysfunction. In our case, the early dysfunctional catheter should be evaluated with contrast studies to achieve accurate information.

Immune thrombocytopenic purpura secondary to COVID-19 vaccination: A systematic review.

Introduction: This systematic review aimed to retrieve patients diagnosed with de novo immune thrombocytopenic purpura (ITP) after COVID-19 immunization to determine their epidemiological characteristics, clinical course, therapeutic strategies, and outcome.

Materials And Methods: We conducted the review using four major databases, comprising PubMed, Scopus, Web of Science, and the Cochrane library, until April 2022. A systematic search was performed in duplicate to access eligible articles in English.

Immunogenicity of COVID-19 vaccines in patients with diabetes mellitus: A systematic review.

Purpose: To evaluate the immunogenicity of COVID-19 vaccines in patients with diabetes mellitus (DM) through a systematic approach.

Method: A comprehensive search was conducted in PubMed, Scopus, and Web of Science with no time restrictions. The search was based on the three main concepts: Covid-19, Vaccine immunogenicity and Diabetes Mellitus.

Genetic diversity and biochemical analysis of Capsicum annuum (Bell pepper) in response to root and basal rot disease, Phytophthora capsici.

This study analyzed the genetic variability and biochemical characteristics of edible and ornamental accessions of pepper, Capsicum annuum, in response to root and basal rot disease (RCR), caused by Phytophthora capsici, using resistance screening and genetic variability via Inter Simple Sequence Repeat marker (ISSR), bio-mass parameters, and enzymatic activity of Peroxidase or peroxide reductases (POX), Superoxide dismutase (SOD), Polyphenol oxidase (PPOs), Catalase (CAT), Phenylalanine ammonia-lyase (PAL), β-1,3-glucanase and phenolic content.
