Incidence of post vitrectomy endophthalmitis in India - A multicentric study by VRSI study Group.

Introduction: The incidence of post vitrectomy endophthalmitis (PVE) is reported to be between 0.02 and 0.84%.

Frequency Rhythmic Electrical Modulation System (FREMS) to alleviate painful diabetic peripheral neuropathy: A pilot, randomised controlled trial (The FREMSTOP study).

Background: Frequency Rhythmic Electrical Modulated System (FREMS) is a non-invasive treatment for chronic pain conditions, but its place in the treatment algorithm for painful diabetic peripheral neuropathy (PDPN) is unknown.

Methods: A pilot, open-label, randomised controlled trial in individuals with PDPN inadequately controlled on at least dual neuropathic pain treatments recruited from primary and secondary care. Participants were randomised 1:1 to FREMS + usual care (n = 13) versus usual care (n = 12).

Isolation and phylogenetic characterization of haemagglutinin and neuraminidase genes of H9N2 low pathogenicity avian influenza virus isolated from commercial layers in India.

Avian influenza is a highly infectious and dynamically evolving disease of birds causing high morbidity and mortality. It is caused by avian influenza virus (AIV) that belongs to the family Orthomyxoviridae. Two types of AIV have been described based on their pathogenicity viz.

Molecular Epidemiology of Nontyphoidal Salmonella in Poultry and Poultry Products in India: Implications for Human Health.

Human infections with non-typhoidal Salmonella (NTS) serovars are increasingly becoming a threat to human health globally. While all motile Salmonellae have zoonotic potential, Salmonella Enteritidis and Salmonella Typhimurium are most commonly associated with human disease, for which poultry are a major source. Despite the increasing number of human NTS infections, the epidemiology of NTS in poultry in India has not been fully understood.

Genetic diversity and population genetic analysis of bovine MHC class II DRB3.2 locus in three Bos indicus cattle breeds of Southern India.

The present study was performed to evaluate the genetic polymorphism of BoLA-DRB3.2 locus in Malnad Gidda, Hallikar and Ongole South Indian Bos indicus cattle breeds, employing the PCR-RFLP technique. In Malnad Gidda population, 37 BoLA-DRB3.

Lambda cyhalothrin induced alterations in Clarias batrachus.

The present study was undertaken to find out the toxic effect of synthetic pyrethroid lambda cyhalothrin on the functioning of endocrine glands in freshwater catfish, Clarias batrachus. The fish were exposed to the pesticide for a period of 45 days at a sublethal concentration of 5.768 ppm.

Structural studies on recombinant T = 3 capsids of Sesbania mosaic virus coat protein mutants.

When expressed in Escherichia coli, the recombinant coat protein (rCP) of Sesbania mosaic virus (SeMV) was shown to self-assemble into T = 3 capsids encapsidating CP mRNA and 23S rRNA derived from the host. Expression of CP-P53A, in which a conserved proline at position 53 in the beta-annulus was substituted by alanine (CP-P53A), also produced similar capsids. Purified rCP and CP-P53A particles were crystallized and X-ray crystal structures of their mutant capsids were determined to resolutions of 3.

Role of metal ion-mediated interactions in the assembly and stability of Sesbania mosaic virus T=3 and T=1 capsids.

Sesbania mosaic virus (SeMV) capsids are stabilized by RNA-protein, protein-protein and calcium-mediated protein-protein interactions. The removal of calcium has been proposed to be a prerequisite for the disassembly of the virus. The crystal structure of native T=3 SeMV capsid revealed that residues D146 and D149 from one subunit and Y205, N267 and N268 of the neighboring subunit form the calcium-binding site (CBS).

T=1 capsid structures of Sesbania mosaic virus coat protein mutants: determinants of T=3 and T=1 capsid assembly.

Sesbania mosaic virus particles consist of 180 coat protein subunits of 29kDa organized on a T=3 icosahedral lattice. N-terminal deletion mutants of coat protein that lack 36 (CP-NDelta36) and 65 (CP-NDelta65) residues from the N terminus, when expressed in Escherichia coli, produced similar T=1 capsids of approximate diameter 20nm. In contrast to the wild-type particles, these contain only 60 copies of the truncated protein subunits (T=1).

Does higher cardiovascular response to ECT predict early antidepressant effect?

Background: Effects of diencephalic seizure generalization during ECT, e.g., cardiovascular response, may be relevant in indexing its therapeutic potency.
