The components of clean fleece weight were examined in five experimental flocks of medium-wool Peppin Merinos. Four single-character selection groups – clean fleece weight plus, clean fleece weight minus, crimps per inch plus, and crimps per inch minus – were examined by measuring fleece production in 18-month-old ewe progeny. Measurements were also made on progeny from the "nucleus" flock, which was selected for clean fleece weight with subsidiary selection for crimps per inch and against fold score. Data were collected in 1952 and 1954. The 1954 figures were obtained from a nutrition experiment in which sheep mere grown from weaning to 18 months on a high and on a low plane of nutrition. The mean measurements of the components of clean fleece weight (W) were compared between flocks using the "percentage deviation" technique. Four comparisons were made: (1) Nucleus/Fleece minus; (2) Fleece plus/Fleece minus; (3) Crimps minus/Crimps plus; (4) high nutritional plane/low nutritional plane. In comparisons (1) , (2), and (3), difference in weight of wool per unit area of skin (w) accounted for nearly all the difference in W. Body weight (S) made a small contribution while difference in fold score (R) was negligible. Fibre density (N) accounted for +86 per cent., and fibre cross-sectional area (A) for –28 per cent., of the difference in W in comparison (1). In comparison (2) the figures were N +47 per cent., A +21 per cent., while the figures for comparison (3) were N –26 per cent., A +121 per cent. The increase in fleece weight was invariably accompanied by a decrease in crimps per inch. In all three comparisons primary density (P) was the major cause of change in N. Fibre length (L) made a uniform contribution of approximately +15 per cent. in the three comparisons.The relative importance of the components of fleece weight was similar at both high and low levels of nutrition.The effect of a high level of nutrition was to produce large increases in A, L, and S. The increase in S was compensated by an equal decrease in P. The increase in fibre diameter was not associated with any change in crimps per inch.

Cattle grow and shed fibre which assists them adapt to seasonal changes in the environment. In the absence of cattle fibre production data for southern Australia, Angus, Hereford, Simmental and Limousin cows and crosses between these breeds grazing perennial pastures at Hamilton, Victoria were sampled in late winter. The fibre-growing area on the sides of cattle was measured, fibre sampled at the mid-side site and the sampling area determined. Fibre was tested for fibre diameter distribution, clean washing yield and fibre length measured. Cows were 3–7 years of age, liveweights were 412–712 kg and the mean fibre-growing area was 2.2 m2. This produced an average 682 g of total fibre (range 346–1175 g). The mean fibre diameter of all fibres was 51.7 µm (range 43–62 µm) and 18% of fibres were <36 µm (range 6–39%). The clean washing yield was 92.4% (range 87.4–95.8%). Fibre length averaged 21 mm. Increasing the age, liveweight and condition score of cows and increasing weight of clean fibre were associated with significant increases in mean fibre diameter. Breed of cattle did not affect fibre production (P > 0.1) but did affect mean fibre diameter (P < 0.05). The quantity of fibre production indicates potential for low value textile production. The high level of total fibre production, twice that of an earlier report, and fibre shedding from cattle suggests that white fibre-producing animals such as Merino sheep, Angora and cashmere goats and alpaca should avoid using cattle-handling facilities, particularly in the month before shearing.

Background: Several studies have shown a relationship between depression and low levels of Vitamin D in the body. At the same time, somatisation is found to be a significant complaint in many patients of depression. Whether somatisation has any relationship with the low levels of Vitamin D, needs further research. Aims: To compare the prevalence of Vitamin D deficiency between depressed and non depressed subjects, and see if somatic presentation of depression has any correlate with Vitamin D deficiency. Design: Observational, cross-sectional, hospital- based study. Materials & Methods: The study was conducted in the Department of Psychiatry, in a Private Hospital. Diagnosed MDD patients consenting to participate in the study, & sex matched controls, comprising of close family members of patients were selected. Detailed assessment of depression symptomatology was done. Assessment of somatization was done using Bradford Somatic Inventory. Blood samples were collected for routine tests and Vitamin D (total) estimation. Results: In the group of MDD patients, the mean age of females is 52 years, & mean age of males is 50 years. In the MDD group, the mean Vitamin D level is 17.12; in the control group, the mean Vitamin D level is 22.19. The difference is statistically significant. Among MDD patients, 70% had deficiency of Vitamin D. In the Severe somatic symptom category, 68.3% had deficiency of Vitamin D; in the Mild somatic symptom category, 66.7% had deficiency of Vitamin D. The difference is not statistically significant. Conclusion: Depression patients have significantly higher proportion of Vitamin D deficiency cases. Depressed patients with higher number of somatic symptoms have lower vitamin D level, but the difference is not significant.

The effect of different planes of nutrition on the wool production of Corriedale wethers at pasture was studied between August 1959 and December 1960. The plane of nutrition was controlled by rate of stocking. The effect of previous nutritional treatment on wool production was slight. It affected wool weight and fibre length for 160 one month and fibre diameter for two months. The differences in current nutritional treatment were accompanied by large differences in wool production except during the spring months. On the highest plane of nutrition the wool production showed little seasonal variation, apart from an initial increase in production during the autumn. On the medium and low planes of nutrition wool growth declined substantially in autumn and winter and increased again in spring. The mean fibre diameter of the wool that was clipped frequently was greater than that of fleece wool obtained from the opposite midside at shearing. Further, in the groups on medium and low planes of nutrition estimates of fleece weight based on the combined weight of periodical clippings were greater than actual fleece weights. It is concluded that, in the dry Victorian summer, wool production is influenced by the plane of nutrition in the previous spring for a short period only, and that in autumn and winter it is dependant almost entirely on the feed immediately available.

Background: Widespread use of lead has caused extensive environmental contamination and health problems in many parts of the world. Children are particularly vulnerable and even relatively low levels of exposure can cause serious health conditions. Our objective was to determine the prevalence of blood lead level in children in industrial city of Nepal, Birgunj.Materials and Methods: The cross sectional study was done on 50 school going student in Birgunj city, Nepal from November 2016 to January 2017. Questionnaire was used to collect data. Capillary blood was drawn and Blood Lead Level was measured immediately. SPSS ver. 22 was used to analyze the data.Results: The mean age of children in study was 12.5 ± 1.11 years.Among 50 children, 54% were male and 46% were female. The mean blood lead level was 20.33±9.36 μg/dl (male 21.08±8.87μg/dl, female 19.46±10.92 μg/dl). All the children in the study have elevated blood lead level and 84% of them have >10 μg/dl. About 26% of children have blood lead level between 15-20 μg/dl, 12% have level 20-25 μg/dl and 4% of them have more than 35 μg/dl.Conclusion: The prevalence of blood lead level in children from the industrial city of Nepal is alarmingly high. Children exposed with chipped paints have high level of blood lead level. However, further study in large population is required to address the current situation regarding the lead exposure to children.

Previous work has shown that, within an Angora goat flock, clean fleece weight is proportional to fleece-free liveweight (FFLwt)2/3 and for goats of the same age and cohort, the mean mohair fibre diameter is proportional to FFLwt1/3. This indicates that fibre length might not be related to the size of animals. This study examines how mohair staple length (SL) is related to FFLwt of Angora goats of different genetic origins over their lifetime and how the relationship varies with other lifetime factors. Measurements were made over 11 shearing periods on a population of Angora goats representing the current range and diversity of genetic origins in Australia, including South African, Texan and interbred admixtures of these and Australian sources. Records of breed, sire, dam, date of birth, dam age, birthweight, birth parity, weaning weight, liveweight, fleece growth and fleece quality were taken for castrated males (wethers) (n = 94 animals). FFLwt were determined for each goat at shearing time by subtracting the greasy fleece weight from the liveweight recorded immediately before shearing. The average of the FFLwt at the start of the period and the FFLWt at the end of the period was calculated. Liveweight change (LwtCh) was the change in FFLwt over the period between shearings. A restricted maximum likelihood model was developed for SL, which allowed the observations of the same animal at different ages to be correlated in an unstructured manner. Average SL differed from ~12.0 to ~14.5 cm, depending on age. There were no consistent effects of season. At any age, an increase of 10 kg LwtCh between animals results in about a 0.34 (s.e. = 0.087) cm increase in SL. There was no evidence of an effect of FFLwt on SL. The results confirm our hypothesis that within a single age cohort of Angora goats, there is very little, if any, relationship between the liveweight and SL of individual animals. This implies that the biological determinants of size of fibres related to cross-sectional area are substantially different to the size determinants of fibre length.

Objective: To investigate the uptake and vaccination willingness of the COVID-19 vaccine among Chinese residents and analyze the difference and factors that impact vaccination. Methods: The snowball sampling method was used to distribute online questionnaires. Relevant sociodemographic data along with the circumstances of COVID-19 vaccination were collected from the respondents. The χ2 test, independent samples t test and binary logistic regression analysis were used to analyze the data. Results: Among 786 respondents, 84.22% had been vaccinated. Over 80% of the vaccinated population have completed all the injections because of supporting the national vaccination policies of China, while the unvaccinated population (23.91%) is mainly due to personal health status. Meanwhile, statistical analysis revealed that the main predictors of not being vaccinated were younger age (3 to 18 years old), personal health status, and lower vaccinated proportion of family members and close friends (p < 0.05). Conclusions: There was a high level of uptake of the COVID-19 vaccine in China, and people who have not been vaccinated generally had a low willingness to vaccinate in the future. Based on our results, it suggested the next work to expand the coverage of the COVID-19 vaccination should be concentrated on targeted publicity and education for people who have not been vaccinated.

Background: Hepatitis B is acute or chronic liver inflammation caused by hepatitis B viral and can progress to hepatic chirrosis or liver cancer. Chronic hepatitis B has a high risk for liver fibrosis. Chronic inflammation and liver fibrosis are interrelated processes. This study aimed to determine the differences in T-regulator cells, Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) between chronic hepatitis B patients with and without liver fibrosis.Method: This study used a cross-sectional method for patients diagnosed with chronic hepatitis B in the Inpatient and Outpatient Department of the Internal Medicine Department  DR. M. Djamil Padang and other hospitals in Padang city for 6 months. Samples were selected by consecutive sampling according to inclusion and exclusion criteria. Liver fibrosis is identified by fibroscan. Data were analyzed by SPSS 21.0.Results: thirty-two patients were diagnosed with chronic hepatitis B and 50% had liver fibrosis. The levels of T-regulator cells in chronic hepatitis B patients without liver fibrosis were 2.08% and liver fibrosis 2.25%, but this difference was not statistically significant (p 0.05). Mean ALT levels in the group without fibrosis were 19 IU/L (7IU/L-71IU/L) and liver fibrosis 61 IU / L (13IU/L-625IU/L). The mean AST level in the group without fibrosis were 15.5 IU/L (10IU/L-32IU/L) and liver fibrosis 35.5 IU/L (10IU/L-476IU/L). The difference between ALT and AST in the two groups was significant (p 0.05). Hepatitis B patients with liver fibrosis had higher ALT and AST levels than without fibrosis.Conclusion: There were differences levels of T-regulator cells in the two groups, but it was not statistically significant. ALT and AST levels were higher in the liver fibrosis group and statistically significant.

Abstract Objective This study sought to determine if there was a difference in the months of oral contraception prescribed by physicians living in U.S. states with a 12-month supply policy compared to physicians in states without a policy. Methods We conducted an exploratory descriptive study using a convenience sample of Obstetrics & Gynecology resident physicians (n=275) in the United States. Standard bivariate analyses were used to compare the difference between groups. Results Few physicians in both groups (3.8% with a policy and 1.4% without a policy) routinely prescribed a 12-month supply of contraception. The mean coverage prescribed by providers in states with and without a policy was 2.81 and 2.07 months (p<0.05). Conclusions The majority of physicians were unaware of 12-month contraceptive supply policies and unable to correctly write a prescription for 12-months of contraception, regardless of whether they lived in a state with a 12-month contraceptive supply policy. Physician education may be needed to effectively implement 12-month contraceptive supply policies.
