Abstract
1. The effect of soybean meal substitution by different concentrations of sunflower meal on egg quality traits of white and coloured dwarf dam lines was investigated. 2. A total of 144 dwarf hens (38 weeks of age) from the same hatch were randomly divided into 12 groups of 12 birds (4 dietary treatments x 3 replicates). 3. A 2 x 4 factorial design was used to study the effect of 2 lines (Factor A) and substitution of soybean meal (SBM) with 4 concentrations (0, 10, 15 and 20%) of sunflower meal (SFM) [Factor B] on egg quality traits of dwarf dam line hens. 4. All the diets were designed to be isocaloric (113 MJ ME/kg) and isonitrogenous (180 g/kg crude protein) The duration of the experiment was 12 weeks. 5. Analysis of variance indicated a highly significant line effect. There were non-significant effects of substitution of soybean meal with different concentrations of sunflower meal on egg quality traits except for Haugh unit. 6. White plumaged dwarf broiler breeder dam line produced significantly fewer, but larger, eggs than coloured dwarf dam line hens.

Abstract
INTRODUCTION We aimed to develop a rapid quantitative-fluorescence polymerase chain reaction (QF-PCR) to detect common foetal aneuploidies in the Singapore population within 48 hours of sample collection in order to alleviate parental anxiety. METHODS DNA from 1,000 foetal samples (978 amniotic fluids, 14 chorion villi and eight foetal blood samples) was analysed using a QF-PCR of 19 microsatellite markers located on chromosomes 13, 18, 21, X and Y. A total of 523 samples were archived before the QF-PCR analysis (archived), while QF-PCR was performed and the results obtained within 48 hours of sample collection in the remaining 477 samples (live). The results were confirmed with their respective karyotypes. RESULTS In total, 47 autosomal trisomies (T) were found: 30 among the archived (three T13, 12 T18, 15 T21) and 17 among the live (four T18, 13 T21) samples. The QF-PCR results were verified with their respective karyotypes. We achieved 100 percent sensitivity (lower 95 percent confidence interval [CI], 92.8 percent) and specificity (lower 95 percent CI, 99.5 percent), and the time taken from sample collection to the obtaining of results for the 477 live samples was less than 48 hours. CONCLUSION Prenatal diagnostic results of common chromosomal abnormalities can be released within 48 hours of sample collection using QF-PCR. Parental anxiety is alleviated and clinical management is enhanced with this short waiting time.

Abstract
Severe factor XIII (FXIII) deficiency is a rare autosomal recessive coagulation disorder affecting one in two million individuals. The aim of the present study was to screen for and analyse F13B gene defects in the German population. A total of 150 patients presenting with suspected FXIII deficiency and one patient with severe (homozygous) FXIII deficiency were screened for mutations in F13A and F13B genes. Twenty-five individuals presented with detectable heterozygous mutations, 12 of them in the F13A gene and 13 of them in the F13B gene. We report on the genotype-phenotype correlations of the individuals showing defects in the F13B gene. Direct sequencing revealed 12 unique mutations including seven missense mutations (Cys5Arg, Ile81Asn, Leu116Phe, Val217Ile, Cys316Phe, Val401Glu, Pro428Ser), two splice site mutations (IVS2-1G>C, IVS3-1G>C), two insertions (c.1155_1158dupACTT, c.1959insT) and one in-frame deletion (c.471-473delATT). Two of the missense mutations (Cys5Arg, Cys316Phe) eliminated disulphide bonds (Cys5-Cys56, Cys316-Cys358). Another three missense mutations, (Leu116Phe, Val401Glu, Pro428Ser) were located proximal to other cysteine disulphide bonds, therefore indicating that the region in and around these disulphide bonds is prone to functionally relevant mutations in the FXIII-B subunit. The present study reports on a fairly common prevalence of F13B gene defects in the German population. The regions in and around the cysteine disulphide bonds in the FXIII-B protein may be regions prone to frequent mutations.

Abstract
1. This experiment was to investigate the effects of increasing dietary vitamin E on physical and biochemical characteristics of semen in Indian reared Kadaknath (KN) cockerels. DL-alpha-Tocopherol acetate was used as the source of vitamin E. 2. A total of 135 one-day-old male KN chicks were randomly selected and divided into 9 groups with 15 chicks in each group (3 dietary treatments x 3 replicates). 3. The basal diet contained 15 IU (10 mg) vitamin E/kg and the two experimental diets were supplemented with 150 IU (100 mg) and 300 IU (200 mg) vitamin E/kg (diets T(2) and T(3), respectively). 4. Physical characteristics in terms of semen volume, sperm concentration, sperm motility and percentage live sperm did not differ significantly, whereas proportion of abnormal and dead spermatozoa were significantly lower and fertility higher in the T(2) group. 5. Biochemical characteristics in term of quantities of protein and nitric oxide (NO) did not differ significantly, whereas the quantity of glucose, acid phosphatase (ACP) and vitamin E were significantly higher in the T(2) group. 6. In contrast, the quantities of alkaline phosphatase (ALP), glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were significantly lower in T(2) group and higher in the T(1) (control) group. 7. From this study it can be concluded that moderate supplementation of dietary vitamin E may be beneficial for physical and biochemical characteristics of semen in Indian reared KN cock.

Abstract
Hepatitis B genotype D (HBV/D) is the most widespread genotype and exists as at least five subgenotypes (HBV/D1-D5). However, little is known about the association of virological characteristics with clinical differences among HBV/D subgenotypes. To investigate the virological characteristics of these subgenotypes and their clinical implications, we selected a cohort of 109 genotype D infected individuals from the state of West Bengal, India, including 68 HBsAg positive patients and 41 with occult HBV infection. Among the HBsAg positive subjects 28 had chronic hepatitis B virus infection, 40 were asymptomatic carriers based on clinical examination, liver function test and ultrasonograph results. Overall, HBV/D1 was found in 17%, HBV/D2 in 29%, HBV/D3 in 34% and HBV/D5 in 20% of the cases. HBV/D1 was significantly associated with chronic liver disease (P = 0.01), and in this subgenotype A1896 (PreC mutations) were most common. Although BCP mutations (A/C1753 and T1762/A1764) were found to be frequently associated with HBV/D2 (33% and 33%) and D5 (47% and 59%), no apparent clinical correlation was observed. On the other hand, occult HBV infection was significantly associated with HBV/D3 infection, along with low level of BCP and PreC mutations and several non-synonymous substitutions in the catalytic reverse transcriptase (RT) domain of polymerase gene. Similar nucleotide substitutions in the surface (S) gene region were observed from both northern and eastern Indian HBV/D3 isolates. In conclusion, HBV/D subgenotypes differ in their mutational patterns in the S, polymerase and the BCP/PreC regions that may influence their clinical outcomes.

Abstract
We present evidence of direct electron tunneling across intrinsic insulating regions in submicrometer wide bridges of the phase-separated ferromagnet (La,Pr,Ca)MnO3. Upon cooling below the Curie temperature, a predominantly ferromagnetic supercooled state persists where tunneling across the intrinsic tunnel barriers (ITBs) results in metastable, temperature-independent, high-resistance plateaus over a large range of temperatures. Upon application of a magnetic field, our data reveal that the ITBs are extinguished resulting in sharp, colossal, low-field resistance drops. Our results compare well to theoretical predictions of magnetic domain walls coinciding with the intrinsic insulating phase.

Abstract
In Nephrotic Syndrome the amount of protein excretion is a reflection of activity of disease. Quantitative measurement of proteinuria by a 24-hour urine collection has been the accepted method of evaluation. Recent studies have shown that calculation of protein/creatinine ratio in a spot urine sample correlates well with the 24-hour urine protein (24-HUP) excretion. A study was conducted to compare the accuracy of a spot urinary protein/creatinine ratio (P/C ratio) and urinary dipstick with the 24-hour urine protein. Fifty two samples from 26 patients of nephrotic syndrome were collected. This included a 24-hour urine sample followed by the next voided random spot sample. The protein/creatinine ratio was calculated and dipstick was performed on the spot sample. This was compared with the 24-hour urine protein excretion. The correlation between the three samples was statistically highly significant (p<0.001) for all levels of proteinuria. The normal value of protein/creatinine ratio in Indian children was also estimated on 50 normal children admitted in the ward without any renal diseases calculated to be 0.053 (SE of mean+/-0.003).

Abstract
This investigation of the outbreak of mass psychogenic illness during July 2007 at three schools in Burdwan was done to observe the description of the epidemic, identify its characteristics and to study any particular factor associated with the spread of illness. Relevant data were obtained from medical and school records. All concurrent factors were considered. All the incidents happened prior to the examinations. There have been differences in presentations and final diagnosis among the schools. Intense media coverage influenced the manifestations. Poor school performance was associated with recurrence of symptoms. So understanding the academic anxiety is important to prevent such outbreaks.

Abstract
INTRODUCTION This study aimed to refine the current quantitative fluorescent polymerase chain reaction (QF-PCR) screen to detect X chromosome anomalies for prenatal diagnosis in the major Southeast-Asian populations. METHODS 100 amniotic fluid samples from Chinese, Malay and Indian origins were subjected to QF-PCR using the X chromosome markers, HPRT, X22 and AMXY, along with the autosomal marker D21S1411. RESULTS Out of the 100 samples tested by markers X22 and HPRT, eight samples were homozygous for both markers, of which seven were resolved by comparison with the autosomal marker D21S1411. CONCLUSION 99 percent of samples could be tested for X chromosome copy numbers, increasing the stringency for detection of X chromosome anomalies by QF-PCR. All results were confirmed by cytogenetics.
