Zika virus (ZIKV) is mosquito-borne flavivirus that caused a significant public health concern in French Polynesia and South America. The two major complications that gained the most media attention during the ZIKV outbreak were Guillain-Barré syndrome (GBS) and microcephaly in newborn infants. The two modes of ZIKV transmission are the vector-borne and non-vector borne modes of transmission. Read More

Tissue Barriers 2022 Jun 21:2090792. Epub 2022 Jun 21.

Faculty of Medicine, Al-Balqa Applied University, Al-Salt, Jordan.

This paper shows how SARS-CoV-2 alters tight junctions (TJs) in human organs. The effect of SARS-CoV-2 on the ACE/Ang II/AT1R pathway and immune cells culminates in the release of numerous pro-inflammatory mediators, leading to the presence of certain symptoms in COVID-19, such as acute lung injury (ALI), pulmonary hypertension, and pulmonary fibrosis. Furthermore, the cytokines released alter different TJs components. Read More

Mini Rev Med Chem 2022 Jun 3. Epub 2022 Jun 3.

Departments of Biochemistry, University of Allahabad, Allahabad 211002, UP-India.

The corona virus disease 2019 (COVID-19), caused by severe acute respiratory syndrome corona virus type 2 (SARS-CoV-2), belongs to emerging and reemerging diseases, which was first identified and reported in Wuhan, China, during December 2019. The genetic sequence of SARS-CoV-2 was similar to SARS virus, a β-corona virus. The epidemiologicalstudies suggest that the transmission of SARS-CoV-2 mainly occurs from an infected person to others through close contact with the respiratory droplets or by having contact with SARS-CoV-2adhering toobjects and surfaces.

Ocular Surface Infection Mediated Molecular Stress Responses: A Review.

Int J Mol Sci 2022 Mar 14;23(6). Epub 2022 Mar 14.

GROW Research Laboratory, Narayana Nethralaya Foundation, Bangalore 560 099, India.

Infection mediated ocular surface stress responses are activated as early defense mechanisms in response to host cell damage. Integrated stress responses initiate the host response to different types of infections and modulate the transcription of key genes and translation of proteins. The crosstalk between host and pathogen results in profound alterations in cellular and molecular homeostasis triggering specific stress responses in the infected tissues. Read More

COVID-19 pandemic: Impact on the rate of viral conjunctivitis.

Arch Soc Esp Oftalmol (Engl Ed) 2022 Feb 31;97(2):63-69. Epub 2022 Jan 31.

Servicio de Oftalmología, Hospital Universitario La Paz, Instituto de Investigación Sanitaria del Hospital la Paz (IDIPAZ), Madrid, Spain.

Objective: The COVID-19 pandemic led Spain to order a state of alert with the cessation of non-essential activities on 14 March 2020, and to implement public health interventions (such as home confinement) and other health recommendations to prevent the spread of the SARS-CoV-2 virus (hand washing and the obligation to wear face-masks). These factors could have influenced the rate of viral conjunctivitis.

Method: In this retrospective, noninterventional, descriptive study, the incidence of viral conjunctivitis in an emergency department of a national hospital is compared over two distinct time periods: pre-COVID (13 March-30 September 2019, one year before the start of the pandemic) and COVID (13 March-30 September 2020).
