Abstract
Acute effects of music and relaxation have not been evaluated in hospitalized subjects with chronic obstructive pulmonary disease (COPD). This study aims to evaluate the acute effects of music and progressive muscle relaxation (PMR) in hospitalized COPD subjects after a recent episode of exacerbation. A Randomized controlled study was performed of pre-test post-test design after recruiting 82 COPD subjects from K.M.C hospitals. All patients were admitted for acute exacerbation and were medically stabilized. After being screened for the inclusion and exclusion criteria, 72 subjects were selected for the study. Demographic and baseline data was taken on the day subjects were screened. Music group listened to a self selected music of 60-80 beats per minute for 30 minutes. PMR group practiced relaxation through a pre-recorded audio of instructions of 16 muscle groups. Outcome variables were Spielberger’s state anxiety inventory (SSAI), Spielberger’s trait anxiety inventory (STAI), dyspnea, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (PR) and respiratory rate (RR). There was statistically significant main effect across the sessions for state anxiety (F = 62.621, p = 0.000), trait anxiety (F = 19.528, p = 0.000), dyspnea ( F = 122.227, p = 0.000), SBP ( F = 63.885, p = 0.000), PR ( F = 115.780, p = 0.000) and RR ( F = 202.977, p = 0.000). There was statistically significant interaction effect between the two groups for state anxiety ( F = 6.024, p = 0.003), trait anxiety ( F = 8.222, p = 0.000), dyspnea ( F = 10.659, p = 0.000), SBP ( F = 12.889, p = 0.000), PR ( F = 4.746, p = 0.008) and RR ( F = 12.078, p = 0.000). There were greater changes observed after the second session in both groups however, change in DBP was not significant in either group. Music and PMR are effective in reducing anxiety and dyspnoea along with physiologic measures such as SBP, PR and RR in two sessions in COPD patients hospitalized with exacerbation. However, reductions in the music group were greater compared to the PMR group.

Abstract
Prosthetic heart valve dysfunction due to thrombus or pannus formation can be a life-threatening complication. The present report describes a 47-year-old woman who developed valvular cardiomyopathy after chorda-sparing mitral valve replacement, and subsequently underwent heart transplantation for progressive heart failure. The explanted mitral valve prosthesis showed significant thrombus and pannus leading to reduced leaflet mobility and valvular stenosis. The present report illustrates the role of the subvalvular apparatus and pannus in prosthesis dysfunction.

Abstract
The role of alcohol in the causation of Fetal Alcohol Syndrome (FAS) has been firmly established. In most cases events leading to its occurrence have been set into motion prior to conception. Alcohol consumption during pregnancy, the sole causative agent of FAS, can therefore be prevented even prior to conception by implementation of preconception counseling (PCC). The present review examines the important issues involved in the implementation of PCC for the prevention of FAS which can be of immense help to the affected population.

Abstract
Piezoresistive micro-cantilevers are interesting bio-sensing tool whose base resistance value (R) changes by a few parts per million (DeltaR) in deflected conditions. Measuring such a small deviation is always being a challenge due to noise. An advanced and reliable DeltaR/R measurement scheme is presented in this paper which can sense resistance changes down to 6 parts per million. The measurement scheme includes the half-bridge connected micro-cantilevers with mismatch compensation, precision op-amp based filters and amplifiers, and a lock-in amplifier based detector. The input actuating sine wave is applied from a function generator and the output dc voltage is displayed on a digital multimeter. The calibration is performed and instrument sensitivity is calculated. An experimental set-up using a probe station is discussed that demonstrates a combined performance of the measurement system and SU8-polysilicon cantilevers. The deflection sensitivity of such polymeric cantilevers is calculated. The system will be highly useful to detect bio-markers such as myoglobin and troponin that are released in blood during or after heart attacks.

Abstract
Extracorporeal photochemotherapy (ECP) has been shown to induce apoptosis in lymphocytes. Until recently the prevailing opinion has been that the monocytes were mainly not affected by this treatment. This study has investigated the effect of ECP and gamma irradiation on monocytes and immature dendritic cells (DC) in vitro and followed the ability of the cells to differentiate and survive post treatment. ECP induced apoptosis in lymphocytes, monocytes and immature DC within 72 h following treatment, in contrast to 30 Gy gamma irradiation, which seemed mainly to affect lymphocytes. The minority of the surviving ECP-treated monocytes presented a reduced ability to differentiate into immature DC within this time frame. We also demonstrated that immature DC after ECP-treatment lost their normal ability to mature on stimulation with lipopolysaccharide. As monocytes and immature DC seem to have a reduced ability to differentiate after ECP-treatment, it is suggested that the therapeutic effect of ECP is caused by in vivo effects of reinfused apoptotic cells, rather than by infusion of monocytes induced to differentiate into immature DC.

Abstract
Objective. Sleep disturbance is common in the subacute recovery phase following brain injury. A previous study from the authors' group found 68% of patients with closed head injury (CHI) had disrupted sleep on a rehabilitation unit. In the present study, the authors investigated whether improvement in sleep efficiency correlates with duration of posttraumatic amnesia (PTA) after CHI. Methods. Fourteen CHI patients were enrolled and followed prospectively. Mechanism of injury included motor vehicle accident, fall, and blunt assault. An actigraph was placed on each subject's wrist within 72 hours of admission to the rehabilitation unit and recorded data for the duration of their stay. A minimum of 7 days of continuous actigraphy data was obtained on all subjects. PTA was measured daily using the Orientation Log (O-LOG). Results. Seventy-eight percent of subjects had mean week-1 sleep efficiency scores of ≤63%. Patients admitted having already cleared PTA had significantly better week-1 sleep efficiency scores than those with ongoing amnesia ( P = .032). For those patients admitted with ongoing PTA, each 10-unit increase in sleep efficiency score correlated with 1 unit increase in O-LOG score ( P = .056). Conclusions. Disrupted sleep is common in the postacute stage following CHI. Improved sleep efficiency correlates with resolution of PTA. Decreased sleep efficiency may negatively affect memory return after traumatic brain injury. Actigraphy is uniquely suited to study the sleep patterns of these patients.

Abstract
BACKGROUND AND PURPOSE MR imaging is an established method for diagnosis and surgical planning of carotid body tumors (CBTs). However no studies have elaborated preoperative objective criteria to predict the Shamblin (surgical) classification of CBTs, an important predictor of vascular morbidity. The purpose of this study was to establish criteria to accurately predict the Shamblin group on preoperative MR imaging for a uniform reporting system. MATERIALS AND METHODS MR images of 9 CBTs in 8 consecutive patients who underwent surgery between 2004 and 2007 were reviewed at a tertiary cancer hospital. The surgical records were blinded to the radiologists. A radiologic classification into 3 types (I, II, and III) based on the maximum degree of circumferential contact of the tumor with the internal carotid artery (ICA) was attempted and correlated with the Shamblin group in surgical records. RESULTS There were 5 type III, 3 type II, and 1 type I tumors. The type I tumor had an ICA maximum circumference of contact less than or equal to 180 degrees , type II tumors had more than 180 degrees and less than 270 degrees , and type III tumors had a maximum circumference of contact of 270 degrees of more. MR imaging accurately predicted the Shamblin group in 8 (100%) of 8 operated tumors. Tumor size and Shamblin group did not have a uniformly predictable relation. CONCLUSIONS Shamblin group can be predicted preoperatively on MR imaging, and the maximum degree of circumferential contact of the CBT with the ICA on axial images is the criterion to predict the Shamblin group.

Abstract
Three guanine-based antiviral drugs, entecavir, lobucavir, and acyclovir showed degradation in presence of sucrose in ready-to-use solutions held at 50 degrees C, with more degradation at pH 4 than at pH 6 or 7. LC/MS analysis of the solutions showed isomeric adducts of the drugs and reducing sugars. Sucrose, a disaccharide and a non-reducing sugar, was the source of monosaccharides, the reducing sugars. Sucrose showed pH-dependent hydrolysis at 50 degrees C into two monosaccharides, fructose and glucose, with more sucrose hydrolyzing at pH 4 than pH 6 or 7. Additionally, the three drugs showed pH-dependent degradation at 50 degrees C in fructose and glucose solutions with the following rank order: pH 7>pH 6>pH 4. This indicated that the increased degradation of the drugs in sucrose solutions at pH 4 was mainly due to more hydrolysis of sucrose into fructose and glucose compared to pH 6 or 7, and subsequent reactions of the fructose and glucose with the drugs. Based on structures of the major degradants, it is proposed that the main cause of the degradation was nucleophilic addition of the primary amine group of the drugs to the carbonyl group of the fructose and glucose. This reaction was facilitated as the solution pH increased from 4 to 7. All the drugs showed satisfactory stability regardless of the storage temperature or solution pH in maltitol, an alternate sweetener. The free aldehyde or ketone group in maltitol precursors is reduced to a hydroxyl group after the hydrogenation process making maltitol less susceptible to nucleophilic addition.
