Ocular tissues can serve as a reservoir for the SARS-CoV-2 virus which can not only cause conjunctivitis but also serve as a source of infection transmission to others. Additionally, the eye and its tear drainage apparatus can track the SARS-CoV-2 from the eye into the respiratory tract of the patient. The potential ocular presence of the SARS-CoV-2 in the eye of a patient can target ACE2 receptors in the endothelium of the co Read More

Background: As countries and industries continue to cope with the unparalleled challenges presented by the novel coronavirus (COVID-19), a specific area of concern has been the uncertainty surrounding the impact of the COVID-19 pandemic on the global and Indian supply chains of the pharmaceutical industry. The COVID-19 crisis has demonstrated the importance of establishing a risk management system that focuses Read More

Fever is a response of a human body, due to an increase in the temperature, against certain stimuli. It may be associated with several reasons and one of the major causes of fever is a mosquito bite. Fever due to dengue virus (DENV) infection is being paid most attention out of several other fever types because of a large number of deaths reported worldwide. Dengue virus is transmitted by biting of the mosquitoes, Aedes ae Read More

The pandemic spread of COVID 19 caused by the novel Coronavirus (SARS-CoV- 2) produced a tremendous effect on the life of humanity across the globe. The epidemiological studies revealed the drastic spectrum of SARS-CoV 2 infection ranging from mere flu-like symptoms to severe respiratory suppression within a short period. Initially, cases have been confined in the emerging point, Wuhan, China. But, within a few Read More

Background: Leishmaniasis is a public health problem and endemic in countries of the tropics and subtropics. An ongoing project with naked LACK (Leishmania homolog of receptors for activated C-kinase) demonstrated that this case of the gene is entirely susceptible to immune response and it does enter the cells effectively. This study aimed at developing a procedure to prepare a type of lipid nanoparticles overloaded with plas Read More

Background: Tobacco mosaic virus (TMV) is the most known virus in the plant mosaic virus family and is able to infect a wide range of crops, in particular, tobacco, causing a production loss. Objectives: Herein, and for the first time in Lebanon, we investigated the presence of TMV infection in crops by analyzing 88 samples of tobacco, tomato, cucumber and pepper collected from different regions in North Lebanon. Methods: Read More

Background: Since December 2019, a novel coronavirus, SARS-CoV-2, has caused global public health issues after being reported for the first time in Wuhan province of China. So far, there have been approximately 14.8 million confirmed cases and 0.614 million deaths due to the SARS-CoV-2 infection globally, and still, numbers are increasing. Although the virus has caused a global public health concern, no effective treatment Read More

Background: Methicillin-resistant Staphylococcus aureus (MRSA) can cause serious infections not only in hospitals but also in the community. The present study was aimed to characterize drug resistance and virulence determinants of community-associated (CA) MRSA isolate compared with healthcare-associated (HA) MRSA. Materials and Methods: A total of 44 patients with HA-MRSA and 11 patients with CA-MRSA infection ( Read More

Background: Drug- and multidrug-resistant Klebsiella pneumoniae isolates have been found worldwide. Treatment failures against carbapenems and extended-spectrum cephalosporins, the currently recommended drugs, contribute to consider K. pneumoniae infections as untreatable infections. The emergence and spread of oxacillinases (OXAs) with carbapenem-hydrolyzing properties are a major concern and seriousl Read More

Background: Increasing prevalence of multiple antibiotic resistance in Klebsiella pneumoniae strains confines the therapeutic options used to treat bacterial infections. Objective: We aimed in this study to investigate the role of AcrAB and qepA efflux pumps and AAC(6′)-Ib-cr enzyme in ciprofloxacin resistance and to detect the RAPD-PCR fingerprint of K. pneumoniae isolates. Methods: A total of , 117 K. pneumoniae isola Read More

Background: Globally, the recent outbreak of Zika virus (ZIKV) in Brazil, Asia Pacific, and other countries highlighted the unmet medical needs. Currently, there are neither effective vaccines nor therapeutics available to prevent or treat ZIKV infection. Objective: In this study, we aimed to design an epitope-based vaccine for ZIKV using an in silico approach to predict and analyze B- and T-cell epitopes. Methods: The predicti Read More

Background: Trichomoniasis is a sexually transmitted disease (STD) prevalent in different parts of the world. The present study was designed to evaluate the scientific output and collaboration of researchers worldwide on trichomoniasis. Methods: In the present scientometric research, all papers conducted on Trichomonas vaginalis (T. vaginalis) published in the time period of 1922 to 2018 were extracted from the Scopus d Read More

Background: Extended Spectrum Beta Lactamase (ESBL) production in gram negative bacteria confers multiple antibiotic resistance, adversely affecting antimicrobial therapy in infected individuals. ESBLs result from mutations in β-lactamases encoded mainly by the blaTEM,blaSHV and blaCTX-M genes. The prevalence of ESBL producing bacteria has been on the increase globally, especially its upsurge among isolates fro Read More

Introduction: Acute pyelonephritis is among the most common bacterial infections. Options for initial treatment of pyelonephritis include an extended-spectrum cephalosporin or a fluoroquinolone. This study aimed to compare the clinical outcomes of patients receiving ceftriaxone to those who received levofloxacin for the treatment of acute pyelonephritis. Methods: In this randomized, open-label trial, hospitalized ad Read More

Background: COVID-19 is a life-threatening novel corona viral infection to our civilization and spreading rapidly. Tremendousefforts have been made by the researchers to search for a drug to control SARS-CoV-2. Methods: Here, a series of arsenical derivatives were optimized and analyzed with in silico study to search the inhibitor of RNA dependent RNA polymerase (RdRp), the major replication factor of SARS-CoV-2. All the optimiz Read More

Introduction: Mycobacterium simiae is an emerging pathogen in Iran and little is known about drug susceptibility patterns of this pathogen. Materials and Methods: Twenty-five clinical isolates of M. simiae from 80 patients with confirmed NTM pulmonary disease were included in this study. For drug susceptibility testing (DST), proportional and broth microdilution methods were used according to the clinical and laborat Read More

Background and Aim: Colorectal Cancer (CRC) is one of the most frequent cancers diagnosed in both men and women worldwide. Fusobacterium nucleatum adhesin A (FadA) has an important potential factor in the development or progression of CRC. The aim of the present study was to evaluate the proliferative effect of recombinant FadA on SW480 colorectal cancer cell line. Materials and Methods: The recombinant pET Read More
