Survey of Calf Management and Hygiene Practices Adopted in Commercial Dairy Farms in Chittagong, Bangladesh

| A survey was conducted to characterize calf management and hygiene practices adopted by dairy farmers at Chittagong, in Bangladesh. A total of 210 dairy farms located in 3 geographically distinct regions in Chittagong division, namely coastal, hilly and plain area, were surveyed. Calf management and hygiene practice related data was collected through a standard questionnaire and all sampled farms were visited once by technical persons and administered the questionnaire by ‘face to face’ method during the period July, 2015 to May, 2016. Statistically significant variations were observed in distribution of different factors through different strata (herd size and region). Among larger farms (>50 cows), 10% had a poor hygiene score whereas 32% of the smaller farms (5-20 cows) belonged to this category. 97% of the large farms used tube well water as the source of drinking water for their calves; whereas 35% of the small farms used surface water. None of the large and medium farm owner said they never clean the calf pen; 47% small farm owners said yes to it. More than half of the smallholders (54%) were discovered with raising other domestic animals and birds within the same premises. Hygiene score and surrounding environment of the farms did not show any regional variation (p>0.05). Remarkably 65% farms of the hilly area used surface water for their calves to drink with. The relationship between management practices and calf mortality/morbidity is complex. Our study design did not allow us to draw conclusions about the management and hygiene practice responsible for calf mortality/morbidity, but knowing the management practices adopted on farms is valuable for bringing attention to herds with less optimal practices and for planning meaningful experiments to explore causal affects.
Age and Sex Related Changes in Corneal Thickness and Anterior Corneal Curvature in Korean Young Population with Orbscan II Topography System

This study investigated, using the Orbscan II topography system, the influence of age and sex related changes on the corneal thickness and anterior corneal curvature, more specifically the fine structure of the cornea, in a Korean young population. The Orbscan II topography system is a computer-assisted slit-beam scanning technology that can map the anterior section of the cornea. The mean central corneal thickness of all subjects was 547.532±44.529 µm. There was no statistical difference (p>0.5) in the mean central corneal thickness between males and females. Sex and age related changes in the mean central corneal thickness had no specific statistical difference (P>0.5). There was a negative correlation between the anterior corneal curvature and the central corneal thickness in all subjects, except for the twenty year olds. However, the thickness relationship between the mean central corneal and the eight paracentral corneal thicknesses had strong statistical differences in all subjects. Also age and sex related changes in the central corneal thickness and the anterior corneal curvature in all subjects had no statistically significant difference, except from 20-26 years old (p>0.05). This information could be a suitable reference basis for future studies in the young population of Asia and for the development of examination tools for corneal refractive surgery.
Ante-partum haemorrhage: An update

Summary Ante-partum haemorrhage is an important cause of maternal and fetal morbidity and mortality, despite modern improvement in obstetric practice and transfusion service. It is defined as any vaginal bleeding from the 20th week of gestation till delivery. The initial management of ante-partum haemorrhage should concentrate on resuscitation and accurate diagnosis. The most important causes are placenta praevia and abruption accounting for more than half the cases. The numbers of cases of placenta praevia and placenta accreta are increasing with the increasing caesarean section rate. In many cases, it is not possible to make a definite diagnosis, despite all the investigations. Development of ultrasound especially transvaginal scan has helped in the definitive diagnosis and management of placenta praevia. Every unit should have a clear protocol for the management of massive haemorrhage, which should be regularly updated and rehearsed.
Jitter measurements in magnetic recording

Transition jitter in magnetic storage can be caused by a variety of factors such as contributions by the medium, head, underlying magnetization, and drive electronics. Medium jitter is attributed to the magnetic microstructure. As the storage density increases, transition noise and medium jitter effects increase significantly and could be potential limiting factors for storage density in the disk drive design. A technique to study medium jitter measurements using in situ methods has been developed. This technique relies on high-resolution measurements developed for in situ imaging. The average positional jitter measurement down-track is repeatable. The measured jitter was about 3.2-6.5 nm on a track with write width about 0.375 /spl mu/m. The cross correlation between the positional jitter mappings from two different recording frequencies shows a strong peak, demonstrating that the jitter maps are independent of the recording frequency and dependent on the medium microstructure.
The role of extended weekends in sickness absenteeism

OBJECTIVES Employees are thought to lengthen their weekends by voluntary absenteeism, but the magnitude of such potentially reversible behaviour is not known. METHODS A follow up study based on employers' registers on the dates of work contracts and absences in 27 541 permanent full time municipal employees in five towns during 1993–7. The absence rate on each weekday separately for all sick leaves and for 1 day sick leaves was determined. RESULTS 3.4% of the male employees and 5.0% of the female employees were on sick leave daily. The mean rate of sickness absence was lowest on Mondays, after which it increased towards Wednesday, and remained on the same level for the rest of the week. This pattern applied to both sexes, to each year of the follow up, and across towns, age groups, and income groups. For 1 day sick leaves, representing 4.5% of the total sickness absenteeism, the rates of sick leave for Mondays and Fridays were 1.4 and 1.9 times greater than those for other weekdays. However, these excess rates account for less than 1% of all days lost due to sickness absenteeism. Extended weekend absences were more common in men, in young employees, and in those in a low socioeconomic position, and they varied between towns. CONCLUSION Extended weekends seem to contribute only marginally to the days lost due to sickness absenteeism.
The shape of geography to come

In this commentary, I offer, from an anarchist–geographic perspective, a constructive critique of certain elements of Simon Springer’s article. I welcome his article for bringing to light some of the more politically problematic elements of (orthodox) Marxist thought. Springer raises important points about the practicalities of social change, but he does so in a rather binaristic manner. Accordingly, I address several elements of Springer’s characterization of both anarchism and Marxism – especially on political organization and praxis – in order to nuance some of his arguments and draw out broader lessons for radical geographical scholarship and the future of the radical/revolutionary left in general.
Urinary isoflavonoid excretion is similar after consuming soya milk and miso soup in Japanese-American women

Based on the hypothesis that isoflavones are absorbed more efficiently from fermented than from non-fermented soya foods, we compared the urinary isoflavonoid excretion (UIE) after intake of miso soup or soya milk. We recruited twenty-one women with Japanese ancestry who consumed standardized soya portions containing 48 mg isoflavones. On day 1, half the women consumed soya milk, the other half started with miso soup. On day 3, the subjects ate the other soya food and on day 5, they repeated the first food. Each participant collected a spot urine sample before and an overnight urine sample after soya food intake. All urine samples were analysed for daidzein, genistein and equol using LC–MS and were expressed as nmol/mg creatinine. We applied mixed models to evaluate the difference in UIE by food while including the baseline values and covariates. Relative to baseline, both groups experienced significantly higher UIE after consuming any of the soya foods. We observed no significant difference in UIE when soya milk was compared to miso soup (P = 0·87) among all women or in the seven equol producers (P = 0·88). Repeated intake of the same food on different days showed high reproducibility within subjects. These preliminary results indicate similar UIE after consuming a fermented soya food (miso) as compared to a non-fermented soya food (soya milk). Therefore, recommendations favouring fermented soya foods are not justified as long as the intestinal microflora is capable of hydrolysing the isoflavone glucosides from non-fermented soya foods.
Greater exercise sweating in obese women with polycystic ovary syndrome compared with obese controls.

PURPOSE We examined estradiol and testosterone effects on thermoregulation in women with and without Polycystic Ovary syndrome (PCOS). We hypothesized that core temperature (Tc) threshold for sweating during exercise is delayed in women with PCOS and that testosterone delays the Tc set point for sweating during exercise. METHODS For 16 d, we suppressed estrogens, progesterone, and testosterone with a gonadotropin-releasing hormone antagonist (GnRHant) in seven women with and seven women without PCOS (control); we added 17[beta]-estradiol (0.2 mg.d-1, two patches) on days 4-16 (E2) and testosterone (2.5 mg.d-1, orally) on days 13-16 (E2 + T). Under each hormone condition, subjects cycled in a temperature of 35 degrees C at 60% of age-predicted HRmax for 40 min. RESULTS Tc sweating threshold was lower in women in the PCOS group compared with those in the control during GnRHant (37.21 degrees C +/- 0.51 degrees C vs 37.70 degrees C +/- 0.12 degrees C, P < 0.05); neither E2 nor E2 + T influenced the thermoregulatory responses in PCOS. E2 decreased Tc sweating threshold in control (37.06 degrees C +/- 0.69 degrees C, P < 0.05), but E2 + T attenuated this response (37.53 degrees C +/- 0.19 degrees C). Peak sweating rate was greater in women in the PCOS group compared with those in the control group during GnRHant (1.06 +/- 0.47 vs 0.47 +/- 0.11 mg.cm-2.min-1) and E2 + T (0.85 +/- 0.41 vs 0.44 +/- 0.10 mg.cm-2.min-1, P < 0.05). Compared with the control group, total sweat losses were greater in the PCOS group during GnRHant (0.614 +/- 0.189 vs 0.419 +/- 0.098 L) and during E2 + T (0.696 +/- 0.281 vs 0.434 +/- 0.164 L, P < 0.05) but not during E2 (0.639 +/- 0.231 and 0.505 +/- 0.214 L for PCOS and control groups, respectively, P = 0.09). CONCLUSIONS Thermoregulation was adequate in women with PCOS; however, the women with PCOS achieved thermoregulation at the expense of producing higher sweat volumes.
Characterization of in vitro transcription and transcriptional products of measles virus

Ribonucleoprotein complexes isolated from measles virus-infected HeLa cells contained an RNA-dependent RNA polymerase activity that catalyzed the incorporation of ribonucleotides into ribonucleic acid. The ribonucleoprotein complexes were composed of measles virus nucleoprotein, phosphoprotein, and a large protein, as well as viral RNA. The kinetics of RNA synthesis at different temperatures, time intervals, and protein, ribonucleotide, and mono- and divalent cation concentrations were analyzed. Enzyme activity was maximum at 4 h at 25 degrees C in the presence of 100 mM Na+-2.5 mM Mg2+-1 mM ribonucleotides. Actinomycin D and alpha-amanitin had no effect on the enzyme activity. Addition of cytoplasmic extracts from uninfected HeLa cells to the reaction mixture did not increase the incorporation of ribonucleotides into RNA. The in vitro synthesized RNAs were characterize by slot blot analysis and quantitated by densitometer scanning. All mRNAs coding for the structural proteins of measles virus were synthesized. Nucleoprotein RNA was the most abundant species made, followed by phosphoprotein, hemagglutinin, fusion protein, matrix protein, and large-protein RNAs. The system described here resulted in the first efficient transcription of measles virus RNA and analysis of products.
Dyadic Coping of Parents After the Death of a Child

This article explores the grief process of parents following the death of a child due to a life-limiting illness, putting particular focus on dyadic coping. Participants included 46 married parents (23 couples). A mixed-methods design was used with in-depth interviews and standardized questionnaires. All parents were interviewed separately. Aspects of common dyadic coping (e.g., sharing emotions or maintaining bonds to the child) helped them work through their grief as a couple but also individually. The authors conclude that dyadic coping plays an important role in grief work and adjustment to bereavement.
Peroxynitrite mediates VEGF's angiogenic signal and function via a nitration‐independent mechanism in endothelial cells

The modulation of angiogenic signaling by reactive oxygen species (ROS) is an emerging area of interest in cellular and vascular biology research. We provide evidence here that peroxynitrite, the powerful oxidizing and nitrating free radical, is critically involved in transduction of the VEGF signal. We tested the hypothesis that VEGF induces peroxynitrite formation, which causes tyrosine phosphorylation and mediates endothelial cell migration and tube formation, by stud‐ ies of vascular endothelial cells in vitro and in a model of hypoxia‐induced neovascularization in vivo. The specific peroxynitrite decomposition catalyst FeTPPs blocked VEGF‐induced phosphorylation of VEGFR2 and c‐Src and inhibited endothelial cell migration and tube formation. Furthermore, exogenous peroxynitrite mimicked VEGF activity in causing phosphorylation of VEGFR2 and stimulating endothelial cell growth and tube formation in vitro and new blood vessel growth in vivo. The selective nitration inhibitor epicatechin en‐ hanced VEGF's angiogenic function in activating VEGFR2, c‐Src, and promoting endothelial cell growth, migration, and tube formation in vitro and retinal neovascularization in vivo. Decomposing peroxynitrite with FeTPPs or blocking oxidation using the thiol donor NAC blocked VEGF's angiogenic functions in vitro and in vivo. In conclusion, peroxynitrite is critically involved in transducing VEGF's angiogenic signal via nitration‐independent and oxidation‐mediated tyrosine phosphorylation. —El‐Remessy, A.

Serum Lactate Dehydrogenase Isoenzyme Pattern in non-Hodgkin's lymphomas

Serum lactate dehydrogenase (S-LDH) and its isoenzyme pattern were assayed in 63 non-Hodgkin's lymphoma (NHL) patients, 37 at diagnosis, 15 at relapse and 11 in complete remission (CR). S-LDH in NHL patients with active disease was higher than in normal subjects and CR patients (p<0.001). Among the isoenzymes, LDH-2 and LDH-5 showed no remarked differences; LDH-1 was reduced and LDH-3 and LDH-4 raised in comparison to the normal group (p<0.001). S-LDH levels and isoenzymes 1 and 4 were influenced by the stage, the histological subgroup and by the presence of general symptoms. In fact, cases in stage IV, with “high-grade malignancy” and with general symptoms, had higher S-LDH levels and more evident LDH-1 and LDH-4 changes than the other stages, the other histopathological subgroups and the cases classified as “A”. S-LDH was the same as in normal subjects in the “low-grade” and “intermediate-grade” malignancies as was LDH-1 in stage II and LDH-4 in stages II and III, in “low-grade” malignancy and in the A cases. In contrast, LDH-3 was always high, with no significant difference in relation to the variables considered. Thus, in NHL, LDH-3 seems to be a reliable marker of the presence of the disease in any case, whereas S-LDH is more related to the spread of the lymphoma.
Linking safety climate perception to types of behavior.

BACKGROUND Certain behavior types can drive the emergence of an unsafe act at the workplace which may be reflected by workers' perceptions toward safety climate. OBJECTIVE The purpose of this study was to explore the relationship between workers' safety climate perceptions (NOSACQ-50 questionnaire) and their behavior types (based on DISC personality traits: Dominance, Influence, Steadiness, and Conscientiousness). METHODS NOSACQ-50 and DISC assessment questionnaires were distributed on employees of four different companies (N = 755) working at hazardous workplaces in different occupational fields: fertilizer, coal mining, and oil & gas. RESULTS Four of the 48 correlation coefficients were statistically significant in which the strongest correlation was found between safety commitment and Influence (I) trait in public self (r = -0.119, p < 0.01). There were two groups of DISC's profile that have a lower perception toward safety climate. The first group was indicated by high scores on Influence (I) trait in public self (17.2% of respondents), and the latter was characterized by low scores on Dominance (D) trait and high scores on Conscientiousness (C) trait in private self (2.8% of respondents). CONCLUSIONS Lower perception toward safety climate was found to be correlated with two groups of DISC's profile. Workers characterized with these two profiles are considered to have priority needs for training or to be assigned to less a hazardous workplace.
Composition and antimicrobial activity of essential oils from aromatic plants used in Brazil

Essential oils from aerial parts of Mentha piperita, M. spicata, Thymus vulgaris, Origanum vulgare, O. applii, Aloysia triphylla, Ocimum gratissimum, O. basilicum were obtained by steam destillation using a Clevenger-type system. These oils were screened for antibacterial and anti-Candida albicans activity using bioautographic method. Subsequently, minimal inhibitory concentration from oils was determined by microdilution method. Most essential oil studied were effective against Enterococcus faecium and Salmonella cholerasuis. Aloysia triphylla and O. basilicum presented moderate inhibition against Staphylococcus aureus while only A. tryphila and M. piperita were able to control the yeast Candida albicans. The oils were analyzed by GC and GC-MS techniques in order to determine the majoritary compounds.
Correlation of scrotal temperature in twins.

BACKGROUND Scrotal temperature and semen quality have been found to be inversely correlated in several studies, and variation in scrotal temperature may contribute to the well known variation in semen quality. The reason for the variation in scrotal temperature is not well understood although determinants could be of a genetic nature. METHODS We monitored scrotal skin temperature for 24 h in a group of monozygotic and dizygotic twins and single-born brothers (n = 48 males). A thermistor was attached to the underwear and the temperature of the scrotal skin was recorded every 5 min using a small portable data logger. RESULTS A correlation in median scrotal temperature was found among monozygotic twins (r = 0.64, P = 0.01), but not in dizygotic twins and single-born brothers (r = 0.17, NS). Similar results were found for other percentiles of temperature. CONCLUSIONS The results suggest a genetic component to the variation in scrotal temperature. An hereditary element in male fecundity may be expressed through scrotal temperature, which constitutes a mechanism independent of those responsible for the development of the sperm producing epithelium.
Lead toxicosis in cattle in Saskatchewan.

The data were compiled from records of this diagnostic toxicology laboratory. The samples were primarily from Saskatchewan and during the period from July 1968 to June 1975, 90 case samples were submitted and confirmed as lead poisoning. Tissues from cases (130 cases) diagnosed as other than lead poisoning were analyzed for lead as well. Lead analysis was carried out by the method used by Cominco Laboratories1 and reported on a wet-weight basis.
Killing of human cytomegalovirus-infected fibroblasts by antiviral antibody and complement.

Complement-dependent cytolytic antibodies (CyAb) to cytomegalovirus (CMV)-infected fibroblasts were detectable in acute- and convalescent-phase sera from renal allograft recipients (n = 44) and nonimmunocompromised patients (n = 14) with symptomatic CMV infection but not in sera from control donors (n = 75; P less than .001 by Wilcoxon rank sum test). Renal allograft recipients with secondary CMV infection had the highest levels of CyAb activity. Activity closely correlated with the serum antibody titer to CMV membrane antigens (r = .9106 by linear regression analysis) and was present in both the IgM and IgG fractions of human sera. IgG F(ab)2 fragments were inactive, thus implicating the classical pathway of complement activation. Maximal CMV-specific lysis was obtained with target cells expressing CMV late membrane antigens (greater than or equal to 72 hr after inoculation) irrespective of the CMV strain used. Adsorption and cold target inhibition studies indicated that the target antigens for the CyAb response are specific for the plasma membrane of CMV-infected cells and may only partly be shared by the virion envelope.
Sphingosine 1‐phosphate in neural signalling and function

Complex sphingolipids are particularly enriched in the central nervous system. Although they were long considered to be structural components of membranes, in the last decades it has become apparent that they have other important functions. More recently, attention has been given to the sphingolipid metabolites ceramide, sphingosine and sphingosine 1‐phosphate (S1P), which have been implicated in the regulation of many aspects of neuronal proliferation, differentiation, survival and apoptosis. Dysregulation of the relative levels of these bioactive sphingolipid metabolites may have implications for a wide array of neurodegenerative disorders and neural malformations. In this paper, we will focus on studies from our laboratory over the past few years using cultured neurons to examine the roles of the sphingolipid metabolite S1P in neuronal survival and differentiation.
Training Spatial Skills: What works, for Whom, and for How Long?

Strong spatial skills predict achievement in STEM fields (e.g., Shea, Lubinski, & Benbow, 2001; Wai, Lubinski, & Benbow, 2009). Improving spatial skills is therefore of both theoretical and practical importance. To determine whether and to what extent training can improve these skills, we meta-analyzed 217 research studies, investigating the magnitude, moderators, durability and generalizability of training on spatial skills. The average effect size (Hedges’ g) for training relative to control was . 47 (SE = .04). Effect sizes were affected substantially by the presence of control groups. When treatment and control group improvements were considered separately, the mean effect size for trained groups was . 62 (SE = .04), while the effect size for control groups was only . 45 (SE = .04). Training effects were durable, and led to near and medium transfer. Considered together, the results suggest that spatially enriched education could pay substantial dividends in increasing participation in STEM disciplines.
