Silica hydrogels as a carbon-free solid media for the culture of diverse organisms.

Bacteriological agar plates are commonly used to carry out experiments for the selective growth of microorganisms and the isolation of single-strain colonies. However, the presence of agar itself may be a confounding factor since it may serve as a source of carbon and energy. Moreover, there have been ongoing constraints on the production and sourcing of agar.

Study of the Anatomical Variations of Spinal Accessory Nerve Seen During Neck Dissection.

In our study, thirty one neck dissections in thirty patients were performed as a part of their treatment for head and neck cancers over a period of one year. In this study, we aimed to report anatomical variations of the spinal accessory nerve (SAN) encountered during neck dissection with respect to important reference points and structures in the neck and correlate them with the length of the neck and height of patient. We preserved SAN in all the neck dissections and studied its course and branching in relation to internal jugular vein (IJV), sternocleidomastoid (SCM) muscle, greater auricular point (GAP), mastoid process, clavicle, angle of mandible, length of the neck and height of the patient.

Images of the month 2: Pulmonary artery pseudoaneurysm formation within uterine leiomyosarcoma metastases.

We present a rare case of pulmonary artery pseudoaneurysm formation in leiomyosarcoma metastases with evidence of acute bleeding and subsequent interventional radiological management.

Surgical Management of Bilateral Abductor Palsy: Comparative Study Between Posterior Cordotomy and Partial Arytenoidectomy.

The aim of this study is to analyse outcome of patients with bilateral abductor palsy undergoing unilateral partial arytenoidectomy and unilateral posterior cordotomy in terms of respiration, phonation and risk of aspiration. Initially tracheostomy was only treatment available to relieve respiratory distress. Now various methods are described e.

Additive effect of photoactivated disinfection on the antibacterial activity of QMix 2in1 against 6-week biofilms: An study.

Background: Evaluation of the additive effect of photodynamic therapy (PDT) on the antibacterial activity of 2.5% sodium hypochlorite (NaOCl) and QMix against 6-week biofilms contaminated root canals.

Aims: To establish the most suitable irrigant for eradication of 6-week biofilms.

Methods: Thirty children with cochlear implants (chronological ages ranging between 4.

Comparison of fracture resistance of endodontically treated teeth restored with nanohybrid, silorane, and fiber reinforced composite: An in vitro study.

Background: The present study was undertaken to evaluate the most suitable restorative for badly mutilated endodontically treated teeth.

Aims: To evaluate and compare the fracture resistance of endodontically treated premolars restored with conventional nanohybrid, silorane composite with glass fibers and newer fiber-reinforced composite in mesio-occluso-distal (MOD) cavities.

Materials And Methods: Sixty extracted human maxillary premolars were selected.

One year comparative clinical evaluation of EQUIA with resin-modified glass ionomer and a nanohybrid composite in noncarious cervical lesions.

Aims: Comparative evaluation of EQUIA with a resin-modified glass ionomer cement (RMGIC; GC Gold Label glass ionomer light cured universal restorative cement) and a nanohybrid composite (Tetric N-Ceram) in noncarious cervical lesions (NCCLs).

Background: To establish the most suitable material for the restoration of NCCLs.

Settings And Design: In vivo study.
