Immunohistochemical colocalization of estrogen receptor-α and GABA in adult female rat hippocampus.

Background: Hippocampus is an important target for estrogen action. It is severely affected in patients of Alzheimer's disease. Much of the current research related to estrogen and brain function is focused in two directions.

Comparison of three different formulations of local anaesthetics for cervical epidural anaesthesia during thyroid surgery.

Background: To compare the efficacy and safety of local anaesthetics under cervical epidural anaesthesia (CEA) using lignocaine (1%), bupivacaine (0.25%) and ropivacaine (0.5%) for thyroid surgery.

Comparison of low doses of intrathecal bupivacaine in combined spinal epidural anaesthesia with epidural volume extension for caesarean delivery.

Aims And Objectives: This study aims to compare relative efficacy of three different doses of intrathecal bupivacaine in combined spinal epidural anaesthesia (CSEA) for caesarean delivery.

Materials And Methods: In a double blinded manner, 204 cases were randomized into three groups: I, II, and III to receive a dose of 4, 5.5, and 7 mg of hyperbaric bupivacaine with a fixed dose of 25 μg fentanyl intrathecally, and Dextran 40 w/v 10 mL given for epidural volume extension (EVE), in CSEA.

A modification in the tube guide to facilitate retrograde intubation: A prospective, randomised trial.

Background: The technique of anterograde over a retrograde guide is considered to be more reliable and preferable in comparison to only retrograde one, for improving the success rate of retrograde intubation. As the prior technique requires a lengthy guidewire to negotiate the whole channel of a tube guide, we designed a side eye at one end of tube guide, which obviated the above requirement while maintaining the integrity of the whole channel assembly. The efficacy of this modified technique was compared with the conventional one for retrograde intubation procedure.

Regenerative endodontics: a state of the art.

Scientific advances in the creation of restorative biomaterials, in vitro cell culture technology, tissue grafting, tissue engineering, molecular biology and the human genome project provide the basis for the introduction of new technologies into dentistry. Non-vital infected teeth have long been treated with root canal therapy (for mature root apex) and apexification (for immature root apex), or doomed to extraction. Although successful, current treatments fail to re-establish healthy pulp tissue in these teeth.
