Amin Talebi Bezmin Abadi was born in 1983 and raised in Sari, Mazandaran Province, Iran. He defended his MSc on Helicobacter pylori infection in 2009. Afterwards, he moved to the Netherlands to conduct research for his PhD thesis under the supervision of Dr. Johannes Kusters at the Utrecht University. Amin returned to Iran in 2013 and is now an Associate Professor in the Department of Bacteriology at Tarbiat Modares University in Tehran. Amin has been a member of the ethics committee at this university since 2014. He is interested in understanding the pathogenic mechanisms driven by Helicobacter pylori and its various virulence factors. Clostridium difficile and Fusobacterium nucleatum are his other research interests.
Un var?n de 29 a?os de edad, copiloto de helic?ptero m?dico, con gran n?mero de horas de vuelo en misiones de transporte a?reo de los pacientes de COVID-19, dio positivo en las pruebas r?pidas de PCR, debido a sospecha cl?nica. Diagnostic?ndose SARS-CoV-2, fue tratado sobre la base del protocolo nacional, permaneciendo en cuarentena domiciliaria durante dos semanas. Habiendo sido eximido de volar, padeci? n?useas, v?mitos, sudores fr?os y palidez facial, mareos y falta de equilibrio, que le abstuvieron de volar durante las primeras tres semanas. No hab?a tenido nunca un problema similar ni factores predisponentes durante su formaci?n como piloto, ni despu?s de esta. Tras un reconocimiento completo se descartaron todas las causas probables.
Twelve months after the realization that SARS-CoV-2 caused a respiratory syndrome in Wuhan, China, with the constantly worsening COVID-19 pandemic and economic crisis globally, and with international news of vaccine development, a new viral variant, referred to as “SARS-CoV-2 VUI-202012/01” or “B.1.1.7” has been reported in London and southeast England. The variant may have emerged in late September 2020 and carries some 17 mutations. Whether a single or a combination of different mutations would change the viral transmissibility, virulence, clinical and epidemiological presentations, or vaccine efficiency is unknown. Transmission by asymptomatic carriers of the new variant is also unknown. Mutation pressure by antiviral agents or v
Antibiotic resistance is now accepted as an inevitable factor in Helicobacter pylori treatment failure, so a survey on the antibiotic susceptibility profile of H.?pylori is welcomed. In addition, the main molecular mechanism of antibiotic resistance in H.?pylori is not fully determined, particularly for metronidazole. Our single-centre study was designed to evaluate the local antibiotic resistance profile of H. pylori strains recovered from individuals with dyspepsia. Gastric biopsy specimens from 200 individuals underwent bacterial culture for H.?pylori, and bacterial identification was confirmed by positive reports from biochemical and genotypic universal protocols. Antibiotic susceptibility tests were performed on the 73 isolates obtaine
IntroductionRecently, Fusobacterium nucleatum has been increasingly implicated as a causative agent of various diseases, e.g., inflammatory bowel disease. Moreover, the gastrointestinal tracts of patients with colorectal cancer (CRC) also have been shown to be colonized by this bacterium. Here, we aimed to determine the prevalence of F. nucleatum among the CRC and non-CRC Iranian patients and investigate potential associations between fadA-positive F. nucleatum and diagnosed CRC cases.MethodsEighty patients, who were admitted to two main hospitals in Tehran, Iran, were enrolled. The patients were aged between 20 and 75 years and were diagnosed by a gastroenterologist. All patients signed their informed consent forms before participating. A

Following the report by the Wuhan Municipal Health Commission about a pneumonia case of unknown cause observed in a patient on 12 December 2019, initial news foreboding a clinical crisis surfaced (The World Health Organization 2020d). The causative agent of the pneumonia was identified and reported some weeks later, confirming that the pneumonia cases were positive with the virus 2019-nCoV (Rothan and Byrareddy 2020). The 2019-nCoV or H-CoV-19 virus (now dubbed SARS-CoV-2) is a member of the betacoronaviruses and can cause acute severe respiratory symptoms or possibly mild, cold-like symptoms (Cheng and Shan 2020). The first PCR-based method for detection of SARS-CoV-2, which was developed in Germany on 17 January 2019, was approved by the
Physical/social distancing, handwashing, respiratory hygiene, and face-masking have been recommended as realistic counterstrategies to control the COVID-19 pandemic. These strategies have been critical in the fight against the present pandemic in many countries. Here, we detail the background to such countermeasures, present some examples in different settings, and finally emphasize that they should remain in place worldwide as a cultural and behavioral “new normal” until a vaccine or a decisive treatment for COVID-19 is developed and made available globally.The outbreak caused by the “severe acute respiratory syndrome coronavirus 2”(SARS-CoV-2) distressed the Wuhan residents in December 2019. Many suffering the resultant “unknown
In February 2020, WHO officially named the novel coronavirus disease as the Coronavirus disease 2019 (COVID-19), and on
PurposeRoles and incidence of some microorganisms that transiently or permanently colonize the human stomach are still unknown despite advances in gastroenterology. We aimed to examine the incidence of four microorganisms, Helicobacter pylori, Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis, in the antral biopsy specimens of patients with gastroduodenal conditions.
The recent pandemic caused by SARS-CoV-2 has now spread worldwide and caused more than 51,000 deaths, by April 2nd 2020. As predicted, there are several obstacles for medical and governmental authorities to efficiently manage this respiratory illness. In spite of appropriated supplies, most hospitals are suffering from a scarcity of free beds, protective masks, sanitizing liquids and even ECMO machines for patients with severe cases. Defeating this pandemic is impossible without united and coordinated international attempts shaped by all countries of the world. We believe that an international scaled-determination is required to diminish the complex impacts of pandemic. The most important priorities are supposed to be i) The development of
