The origin of Indonesian cattle and conservation genetics of the Bali cattle breed

Both Bos indicus (zebu) and Bos javanicus (banteng) contribute to the Indonesian indigenous livestock, which is supposedly of a mixed species origin, not by direct breeding but by secondary cross-breeding. Here, the analysis of mitochondrial, Y-chromosomal and microsatellite DNA showed banteng introgression of 10-16% in Indonesian zebu breeds with East-Javanese Madura and Galekan cattle having higher levels of autosomal banteng introgression (20-30%) and combine a zebu paternal lineage with a predominant (Madura) or even complete (Galekan) maternal banteng origin. Two Madura bulls carried taurine Y-chromosomal haplotypes, presumably of French Limousin origin. There was no evidence for zebu introgression in five populations of the Bali cattle, a domestic form of the banteng.

Women's health: explaining the trend in gender ratio in Iran over half a century (1956-2006)

OBJECTIVES

Changes in gender ratio generally reflect differences in mortality rates in men and women. Female mortality rates, on the other hand, can be used as an index of the trends in women's health. This study looks at the trend in the population gender ratio from 1956 to 2006, with a focus on analysing mortality rates and hence the overall health of Iranian women over the last 50 years.

STUDY DESIGN

Cohort-type analysis using data from the last five population censuses in Iran.

METHODS

Data were used to calculate gender ratios and analyse their trends over the 50-year period from 1956 to 2006.

RESULTS

According to the 1956 Census, there were 98 men for every 100 women in the 25-34 years age group (male:female ratio=0.98). In the next census, conducted 10 years later (1966), the gender ratio increased to 121 in the 39-44 years age group. The discrepancy increased in later censuses; this trend indicates that mortality in the 25-34 years age group was significantly higher in 1956-1966 compared with subsequent decades. The social and economic crises of the 1940s probably left women of reproductive age exceptionally vulnerable to a wide range of adverse health outcomes. The fact that the trend ceased in 1976 with no further increase in the gender ratio may be due to improving social conditions and greater effectiveness of healthcare programmes directed at women.

CONCLUSION

As life expectancy is calculated on the basis of the conditional probability of death over specific intervals, the apparent discrepancy between the current gender ratios and life expectancy data may be due to higher female death rates before 1976.

Nutritional quality of germinated cowpea flour (Vigna unguiculata) and its application in home prepared powdered weaning foods

Amino acid profiles, protein digestibility, corrected amino acid scores (PDCAAS), chemical scores, essential amino acid indexes, and calculated biological values of controlcowpea flour (CCF), germinated cowpea flour (GCF) prepared from cowpeas germinated at 25 degrees C for either 24 h or 48 h and weaning foods prepared from cowpea flours were determined. Locally available rice, cowpea flour, banana-pumpkin slurry, and skim milk powder and sucrose in the ratio 35:35:15:15:5 were used to formulate weaning food containing not less than 15% protein. The ingredients were cooked into a slurry and oven-dried to produce flakes. The nutritional and sensory qualities of the weaning products were evaluated. Germination had little effect on the amino acid profile of cowpeas. In vitro protein quality and starch digestibility were improved in germinated cowpea flour. The PDCAAS of 24 h germinated cowpea flour (GCF) weaning food was higher (55.49%) than CCF-weaning food (46.74%). Vitamin A activity in 24 h GCF weaning food was higher than in CCF-weaning food. In vitro starch digestibilities of 24 h GCF and 48 h GCF-weaning foods were higher than that of CCF weaning food. The 24 h GCF-weaning food which had a higher overall acceptability score by sensory panelist than 48 h GCF and CCF-weaning food is recommended for household consumption.

Cytotoxic 3,4-secoapotirucallanes from Aaglaia argentea bark

Nine 3,4-secoapotirucallanes, argentinic acids A-I, were isolated from the bark of Aglaia argentea and transformed to their methyl esters 1-9. The structures were determined by spectral and chemical means. Compounds 1-8 showed moderate cytotoxic activity against KB cells (IC50 1.0-3.5 microg/mL).

Argenteanones C-E and argenteanols B-E, cytotoxic cycloartanes from Aglaia argentea

Seven new cycloartanes, argenteanones C-E (4-6) and argenteanols B-E (7-10), have been isolated from Aglaia argentea leaves. All of these compounds possess significant cytotoxic activity against KB cells (IC50 values between 3.7 and 6.2 micrograms/mL). Structure elucidation was performed by 2D NMR spectroscopy, aided by molecular modeling in the case of the side chain of compound 7.

The socioemotional development of orphans in orphanages and traditional foster care in Iraqi Kurdistan

In order to investigate orphans' situation and development in Iraqi Kurdistan, samples from the two available orphan care systems, the traditional foster care and the modern orphanages, are examined at an index test and at 1-year follow-up regarding competency scores and behavioral problems at both test occasions, and post-traumatic stress reactions at a 1-year follow-up. Achenbach Child Behavior Check List (CBCL) and two instruments regarding post-traumatic stress disorder (PTSD) were used. While competency scores showed an improvement in both samples at the follow-up test, the problem scores increased in the orphanage sample and decreased among the foster care subjects. Moreover, the orphanage sample reported higher frequency of post-traumatic stress disorder (PTSD) than the foster care children. The results are discussed with regard to the value of the Kurdish society's own traditions in taking care of orphans.

Three-contrasts method hysteroscopy: the use of real-time ultrasonography for monitoring intrauterine operations

Thirty-four patients were operated on by the technique of three-contrasts method hysteroscopy in this article. In three-contrasts method hysteroscopy, sonography guidance was used instead of laparoscopy guide. The distending medium introduced into the uterus during hysteroscopy and injected normal saline into the bladder and abdomen (which flowed into the posterior cul-de-sac) created these three contrasts. As a result, the walls of the uterus were clearly seen at sonography. Advantages and disadvantages of this technique have been described in detail.

Adhesion formation after ovarian electrocauterization on patients with polycystic ovarian syndrome

The rate of adhesion formation after ovarian electrocauterization has been described in two selective and unselective groups of patients with PCOS. The rate of this complication in the selective group was 0 from 16 ovaries and in the unselective group (5/25). However, the rate of major adnexal adhesion in the unselective group was 1 from 25 ovaries.
