PURPOSE We conducted a clinical study to evaluate the effects of neurotization, especially comparing the total contralateral C7 (CC7) root transfer to hemi-CC7 transfer, on total root avulsion brachial plexus injuries (BPI). METHODS Forty patients who received neurotization for BPI were enrolled in this prospective study. Group 1 (n = 20) received hemi-CC7 transfer for hand function, while gr...

The cardia bifida in amphibians has the bulboventricular loop of the two hemi-hearts convex towards the mid-line. In birds the two loops have been reported to be convex towards the outside because all the experimental methods of producing cardia bifida in birds, unlike amphibians, impede the closure of the foregut. The morphologic expression of each cardiac primordium was studied without alteri...

OBJECTIVE To evaluate cerebellar volume changes and the asymmetry of patients with benign paroxysmal positional vertigo (BPPV). METHODS The cerebellar hemispheres` volumetric symmetry were evaluated using a stereological method on MR images. The study included 15 patients with BPPV, and 14 age-, and gender-matched control subjects. The cases were admitted to the Departments of Otolaryngology,...

The 6.7 murine monoclonal antibody (mAb) recognizes the human CD18 antigen and is therefore of interest as an anti-inflammatory agent. The 6.7 heavy variable chain (VH) was humanized using the closest human germline sequence as the template on to which to graft the murine complementary determining regions (CDRs). Two versions were proposed, one in which the residue proline 45 of the murine form...

BACKGROUND Respiratory virus infections in children are a leading cause of morbidity and mortality worldwide. METHODS A total of 897 clinical specimens were collected from February 2007 to January 2008 and transported to the National Influenza Center. Two hundred and two samples belonged to children under the age of six from 897 specimens, described above, were selected. Then they were tested...

OBJECTIVE Aortic valve replacement has been approached by standard sternotomy. We described a technique of aortic valve replacement where the aortic valve is exposed through a hemi-sternotomy. Good exposure is obtained for aortic valve surgery with standard aortic and right atrial cannulation to establish cardiopulmonary bypass (CPB). METHODS From October 1996 to April 1997, 19 consecutive ao...

Saccharum officinarum bagasse (common name: sugarcane bagasse) and Pennisetum purpureum (also known as Napier grass) are among the most promising feedstocks for bioethanol production in Argentina and Brazil. In this study, both biomasses were assessed before and after acid pretreatment and following hydrolysis with Nasutitermes aquilinus and Cortaritermes fulviceps termite gut digestome. The ch...
