Effect of π-Conjugated Spacer in N-Alkylphenoxazine-Based Sensitizers Containing Double Anchors for Dye-Sensitized Solar Cells.

A series of novel double-anchoring dyes for phenoxazine-based organic dyes with two 2-cyanoacetic acid acceptors/anchors, and the inclusion of a 2-ethylhexyl chain at the nitrogen atom of the phenoxazine that is connected with furan, thiophene, and 3-hexylthiophene as a linker, are used as sensitizers for dye-sensitized solar cells. The double-anchoring dye exhibits strong electronic coupling with TiO, provided that there is an efficient charge injection rate. The result showed that the power conversion efficiency of with thiophene linker-based cell reached 3.

Cross-country transport and isolation and identification of by use of alternate sources of blood supplemented media among laboratories in India.

Background: The isolation of S. pneumoniae (Sp) depends on specimen integrity / transport, media and expertise. The non-availability of sheep blood agar poses a challenge in identification of colonial morphology and identification in India.

Simple and economical method for identification and speciation of Staphylococcus epidermidis and other coagulase negative Staphylococci and its validation by molecular methods.

Coagulase-negative staphylococci (CoNS) have been increasingly recognized as a clinically important group of species that can cause several opportunistic nosocomial infections. There are at least 47 known species of Staphylococci and to differentiate all these species >40 biochemical tests need to be performed. The present study was able to refine the CoNS identification process by using only five tests to identify S.

Bacteriological Quality of Treated Water and Dialysate in Haemodialysis Unit of A Tertiary Care Hospital.

Introduction: Haemodialysis is one of the treatment modalities for patients suffering from end stage renal disease (ESRD). Dialysis patients are exposed to large volumes of water for production of dialysis fluids. Treated water and dialysate come in direct contact with the patient's bloodstream.

Diphtheria-like illness in a fully immunised child caused by Corynebacterium pseudodiphtheriticum.

Corynebacterium pseudodiphtheriticum is a common commensal flora of the upper respiratory tract in humans. Though the pathogenicity of C. pseudodiphtheriticum is not rare, its role as an opportunistic pathogen is mainly limited to the lower respiratory tract, particularly in patients with underlying systemic conditions or immune-compromisation.

Retinal vasculitis as an early indicator of systemic candidal abscesses in a premature infant.

We report a case of fungal retinal vasculitis in a 32 week gestational age, 1200 g premature infant detected during routine screening for retinopathy of prematurity at 78 days of age. The patient subsequently developed sepsis with perinephric abscess but responded rapidly to systemic therapy. Fortuitous detection of retinal vasculitis as the first evidence of a systemic fungal infection in an immunocompetent and asymptomatic infant has not, to our knowledge, been previously reported.

Disseminated nocardiosis in an elderly patient presenting with prolonged pyrexia: Diagnosis by thyroid abscess culture.

We report a case of nocardiosis in an immunosuppressed elderly patient who presented with prolonged pyrexia. Nocardia asteroides was isolated from the thyroid, with CT scan evidence of dissemination to the brain, abdomen and lungs. The patient succumbed to illness despite aggressive therapy.

Injection site abscess due to Mycobacterium fortuitum: a case report.

Injection abscess is an iatrogenic infection occurring as an isolated case or as cluster outbreak. These infections occur due to contaminated injectables or lapse in sterilisation protocol. While pathogens such as Pseudomonas, Klebsiella, E.

A case of injection abscess due to Salmonella typhi.

To the best of our knowledge, injection abscess due to Salmonella typhi has not been reported earlier. A patient with fever of unknown origin was diagnosed as suffering from typhoid fever, administered a course of ceftrioxone but patient developed an injection abscess due to S. typhi, abscess was drained and patient was started on ciprofloxacin to which he responded favourably.

Evaluation of ParaHITf strip test for diagnosis of malarial infection.

This study sought to determine whether dip stick strip test containing antibody for Plasmodium falciparum histidine rich protein-II (PfHRP-II) antigen could be used for identification of P. falciparum and P. vivax malaria in man.

A comparative study of pleurodesis using talc slurry and bleomycin in the management of malignant pleural effusions.

Objective: Differing success rates of various pleurodesis agents have been reported in the management of malignant pleural effusions. A randomized clinical trial was conducted to compare the efficacy of two commonly used agents, talc and bleomycin, for the pleurodesis of malignant pleural effusions.

Methodology: Inclusion in the study required proof of a malignant pleural effusion by fluid cytology or pleural biopsy.

The diagnostic yield of pleural fluid cytology in malignant pleural effusions.

Background: The development of a pleural effusion in a patient with a known malignancy often raises the possibility that the effusion is due to malignant involvement of the pleura. Accurate diagnosis of the cause of the pleural effusion in such a patient is essential as the treatment and prognosis may vary. Currently, thoracentesis and cytologic analysis of pleural fluid cytology is usually the initial diagnostic step.
