Depth, size of infiltrate, and the microbe - The trio that prognosticates the outcome of infective keratitis.

Purpose: To analyze the influence of infiltrate size, depth, and organism on the outcome of microbial keratitis.

Design: Retrospective comparative study.

Methods: Medical records of patients with infective keratitis, who reported from January 2015 to December 2019 to a tertiary eye care center, were analyzed.

Aqueous deficiency dry eye in post conjunctivitis cicatrization - Effect of deep thermal punctal cautery.

Purpose: To evaluate the effect of deep thermal punctal cautery in eyes with post-conjunctivitis cicatrization.

Methods: This retrospective study consisted of patients who underwent deep thermal punctal cautery for post-conjunctivitis dry eye (PCDE). The diagnosis was based on a history suggestive of viral conjunctivitis in past followed by the onset of present clinical features of aqueous deficiency dry eye (ATD).

Possible Synergistic Role of Cryo-Alcohol Therapy in Infectious Scleritis-Scope and Rationale for Expanding Indications and Review of the Literature.

Purpose: The purpose of this study was to highlight the use of topical ethanol as an adjunct to cryotherapy, termed cryo-alcohol therapy, in the management of fungal/acanthamoeba scleritis along with a review of the literature.

Method: Retrospective interventional case reports of fungal and acanthamoeba scleritis along with a review of the literature.

Results: The patient with circumferential necrotic fungal scleritis resolved in 6 weeks achieving a best-corrected visual acuity (BCVA) of 20/20, and the patient with acanthamoeba scleritis is awaiting optical keratoplasty after complete resolution in 8 weeks.

Genome Sequences of RIGVIR Oncolytic Virotherapy Virus and Five Other Echovirus 7 Isolates.

We report here the nearly complete Illumina-sequenced consensus genome sequences of six isolates of echovirus 7 (E7), including oncolytic virotherapy virus RIGVIR and the Wallace prototype. Amino acid identities within the coding region were highly conserved across all isolates, ranging from 95.31% to 99.

An appraisal of biological responses and network of environmental interactions in non-mining and mining impacted coastal waters.

The coastal waters of Goa and Ratnagiri lying on the West coast of India are influenced by terrestrial influx. However, Goa is influenced anthropogenically by iron-ore mining, while Ratnagiri is influenced by deposition of heavy minerals containing iron brought from the hinterlands. We hypothesize that there could be a shift in biological response along with changes in network of interactions between environmental and biological variables in these mining and non-mining impacted regions, lying 160 nmi apart.

Effect of TiO2 nanoparticles on the hydrogen sorption characteristics of magnesium hydride.

The present paper explores the enhancement in hydrogen sorption behavior of MgH2 with TiO2 nanoparticles. The catalytic effect of TiO2 nanoparticles with different sizes (7, 25, 50, 100 and 250 nm) were used for improving the sorption characteristics of MgH2. The MgH2 catalyzed with 50 nm of TiO2 exhibited the optimum catalytic effect for hydrogen sorption behavior.

Dysregulation of cytokine response in Canadian First Nations communities: is there an association with persistent organic pollutant levels?

In vitro and animal studies report that some persistent organic pollutants (POPs) trigger the secretion of proinflammatory cytokines. Whether POP exposure is associated with a dysregulation of cytokine response remains to be investigated in humans. We studied the strength of association between plasma POP levels and circulating cytokines as immune activation markers.

CpG protects human monocytic cells against HIV-Vpr-induced apoptosis by cellular inhibitor of apoptosis-2 through the calcium-activated JNK pathway in a TLR9-independent manner.

Monocytic cells survive HIV replication and consequent cytopathic effects because of their decreased sensitivity to HIV-induced apoptosis. However, the mechanism underlying this resistance to apoptosis remains poorly understood. Lymphocytic cells are exposed to microbial products because of their translocation from the gut in persons with chronic HIV infections or following coinfections.

Immunogenicity of Plasmodium vivax combination subunit vaccine formulated with human compatible adjuvants in mice.

An effective malaria vaccine will probably require the delivery of multiple antigens that induce several layers of immunity. Malaria antigens expressed on the surface and in apical organelles of blood-stage merozoites are potential vaccine candidates given their importance in the invasion of erythrocytes. The present study examined the kinetics of humoral response in BALB/c mice following immunization with combination of two blood-stage Plasmodium vivax invasion related molecules, the N-terminal, cysteine-rich region II of P.

Definition of structural elements in Plasmodium vivax and P. knowlesi Duffy-binding domains necessary for erythrocyte invasion.

Plasmodium vivax and P. knowlesi use the Duffy antigen as a receptor to invade human erythrocytes. Duffy-binding ligands belong to a family of erythrocyte-binding proteins that bind erythrocyte receptors to mediate invasion.
