＂They Are Kind of Like Magic＂ Why U.S. Mothers Use Baby Videos With 12- to 24-Month-Olds

Although the American Academy of Pediatrics （AAP） recommends no ＂screen time＂ for children under age of two, parents in the US are ignoring this edict. Routinely, mothers are exposing their babies to media crafted specifically for this age group. This study seeks to ascertain the reason. What beliefs do mothers hold regarding the marketing of such media and the expected benefits to their young ones？ How does the use of videos such as Baby Einstein benefit the mother？ Although mothers reported that video creators want them to think the videos are educational, they are skeptical. However, they continue to let babies watch this ＂safe＂ content. Among the 28 mothers interviewed for this project, only four claimed to always watch with their child; the remainder used ＂video time＂ to do household chores. Overwhelmingly, mothers heard positive comments about videos from fellow parents, but rarely heard from their pediatricians about possible negative effects on the under-two＇ s.

Methionine Levels in the Diet for Pregnant Female Rabbits Affects Hair Follicles Development of Baby Rabbits

[ Objective] This experiment was conducted to study methionine level in diet for prepnant famale rabbits on the development of hair follicles of baby rabbits. [ Method] Fifty-four Angora female rabbits with similar body weight, parities and historicaly hair yield were randomly assigned to three groups with eighteen replicates in each group and one rabbit per replicate. Rabbits during pregnancy were fed diets with 0.5!%, 0.71% and 0.91% methionine, respectively. Hair follicle density and diameter in the back skin were determined at 18-day fetus. 26-day fetus, newborn and 2- month-old,and hair fiber diameter at 2-month-old was also determined. [ Result] The results showed as follows： （1） hair follicle density and diameter at each stage,coarse hair fiber diameter at 2-month. old showed a tendency of increasing with dietary methionine level（ P 〉0.05）, fine hair diameter in 0.91% group was significantly larger than that in 0.51% group at 2-month-old （ P 〈 0.05）. （2） With the development of baby rabbit,the ratio of secondary follicle and primary follicle increased gradually, at newborn of rabbits in group 0.51%, 0.71% and 0.91%were 5.84, 5.56 and 5.81, respectively, and at 2-month-old were 8.47, 7.97 and 8.03, respectively. （3） Baby rabbits in group 0.51%, 0.71% and 0.91% gained increases of primary follicle diameter by 0.58, 0.57 and 0.61pm/d from 26-day fetus to birth, and 0.11,0.11 and 0.12 prn/d from birth to 2-month-old, re- spectively; they also gained increases on secondary follicle diameter by 0.0018,0. 012 and 0. 011prn/d from birth to 2-months-old, respectively. [ Conclusion] These results indicate that increase of methionine level in diet for female rabbits during pregnancy is a stimulation factor for the development of hair follicle of baby rabbits, and can improve their hair fiber diameter.

A new peroral mother-baby endoscope system for biliary tract disorders

AIM: To investigate a new mother-baby system, consisting of a peroral cholangioscope and a duodenoscope in patients regarding its feasibility. METHODS: In the study period from January 2007 to February 2010, 76 consecutive patients(33 men, 43 women; mean age 63 years old) were included in this pilot series. Endoluminal images and biopsies were obtained from 55 patients with indeterminate strictures, while 21 patients had fixed filling defects. The diagnostic accuracy of peroral cholangioscopy(POCS) in the visualization of strictures and tissue sampling was evaluated, and therapeutic success was monitored. Followup was performed over at least 9 mo. RESULTS: A total of 55 patients had indeterminate strictures. Using the criteria "circular stenosis" and "irregular surface or margins", POCS correctly described 27 out of 28 malignant biliary strictures and 25 out of 27 benign lesions(sensitivity, 96.4%; specificity, 92.6%, diagnostic accuracy 94.5%). Visually targeted forceps biopsies were performed in 55 patients. Tissue sampling during POCS revealed malignancy in 18 of 28 cases(sensitivity: 64.3%). In 21 patients with fixed filling defects, 10 patients with bile duct stones were successfully treated with conventional stone removal. Nine patients with difficult stones(5 giant stones and 4 intrahepatic stones) were treated with visually guided laser lithotripsy. Two patients in the group with unclear fixed filling defects had bile duct adenoma or papillary tumors and were surgically treated. CONCLUSION: The new 95 cm POCS allows for accurate discrimination of strictures and fixed filling defects in the biliary tree, provides improved sensitivity of endoscopically guided biopsies and permits therapeutic approaches for difficult intrahepatic stones.

Heroic Woman Images Against Male Power in Tar Baby

Ecofeminism is a theory that combines women's unfair condition with nature's overuse by human.It "argues that a strong parallel exists between the oppression and subordination of women in families and society and the degradation of nature through the construction of differences into conceptual binaries and ideological hierarchies that allow a systematic justification of domination by subjects classed into higher-ranking categories over objects classed into lower-ranking categories" (Miao 184). Tar Baby is the fourth work of Tony Morrison which explores African-Americans' poor status, especially black women's. From ecofeminism's perspective, women and nature share same destiny. Being fed up with the bad condition, women has struggling against male world and tried to win their own happiness and identity, appealing to mutual respect and understanding.

Determination of Iron in Baby Weaning Food and Powder Milk

Infant formula provides the largest, if not sole, source of nutrition for an extended interval;the nutritional adequacy of the formula must be confirmed and the indications for its use were well understood. Both iron deficiency and iron excess during the fetal and neonatal period bode poorly for developing organ systems. Voltammetry is analytical method based on current potential measurements in electrochemical cells. In this study the concentration of iron in four brands of powder milk and baby food (based on rice and based on wheat) was analyzed with DPASV and voltammeter device. Total Means ± SE of Iron in baby foods and powder milk (n = 40) were 8.55 ± 1.18 mg/100g, 5.21 ± 0.66 respectively. Iron level in baby food type I and II was lower than labeled value (p p < 0.05).

Properties of Baby Food Developed from Orange-Fleshed Sweetpotato and Mangoes

Vitamin A Deficiency (VAD) is a major concern in the world today and is a risk for children in developing countries. Trends have shown that food based interventions are the preferred long-term solution in controlling VAD as opposed to supplements. The orange-fleshed sweetpotato and mangoes are rich in beta-carotene, yet they are not fully utilized. A processed product from these raw materials will make use of surplus produce, promote year round utilization, increase the economic value of the crops and provide variety and convenience of uses. The roots were obtained from the field station, University of Nairobi, while the mangoes were purchased from the local market. The roots were washed, peeled and sliced. They were boiled to softness and mashed. The mangoes were washed, peeled, sliced and pureed in a blender. The two raw materials were mixed using six different formulations. Each formula was pasteurized at 80°C for 5 min in a batch pasteurizer, packaged by hot filling, cooled immediately and stored. The cooking time for the sweetpotatoes was 19.5 min. Losses of beta-carotene and ascorbic acid ranged from 17% - 21% and 18% - 28% respectively after pasteurization. The total solids increased by 3% on average. Changes due to storage of the product at 25°C could be detected by sensory analysis only after six months of storage. After storage, beta-carotene and ascorbic acid decreased by 18% and by 45% respectively. The final stored product could provide 73.7% and 64.5% of retinol equivalent for infants and 1 - 10 year-olds respectively. It could also provide 48.9% of ascorbic acid for children 1 - 10 years old, when consumed in amounts of 100 g per day.

Foetal Position: Can It Be Used to Predict the Sex of Unborn Baby?

Sex is used to define the biological categorization of a human being as either a male or female. Globally, most of the pregnant women have expressed desire to know the sex of their babies prenatally. To determine sex of the baby before birth, both traditional and modern sex prediction methods have been used. The study aimed at answering the question;can foetal position and sex be related? If so, can it be used to predict the sex of the baby? Analytical perspective utilizing quantitative approach was conducted in a Referral County Hospital to collect data from a sample size of 340 women who were admitted in labour. Selection was done through convenience sampling method. Data were cross tabulated to determine variable frequencies and establish the association, while chi-square was used to test the study hypothesis. Overall results revealed statistically significant relationship between foetal position and sex of the baby (P = 0.001). Majority of female neonates (74.4%) had adopted right occipital anterior, while most of male neonates (57.4%) had adopted left occipital anterior. It follows then, that sex of the baby may be related to the foetal position. This knowledge may be used by the midwives to predict the foetal sex for the women who may not afford ultrasound scan. Further research may be necessary in a different setting.

Determinants of Breast-Feeding Initiation Time among Newborns Delivered in a Tertiary Baby Friendly Health Facility in Enugu, Nigeria

Background: The importance of early breastfeeding initiation to both the mother and infant is enormous as it reduces the likelihood of neonatal mortality as well as maternal postpartum haemorrhage. The objectives of the study were to assess the prevalence and determinants of correct breastfeeding initiation time among newborns delivered at the University of Nigeria Teaching Hospital, Enugu. Methods: This was a cross sectional descriptive study. Relevant maternal and new-born birth characteristics were obtained using a pretested semi-structured questionnaire. Data were analyzed using SPSS version 20.0. Multivariate logistic regression was used to determine the factors that are significantly associated with correct breastfeeding initiation time with the level of significance set at p Results: A total of 321 mother-newborn pairs were studied. 86 (26.8%) of the respondents correctly initiated breastfeeding within 1 hour of delivery. Planned pregnancy, pre-pregnancy decision on infant feeding options, primiparity, vaginal delivery and breast milk as first food given to the neonate post-delivery were associated with increased likelihood of correct breastfeeding initiation time. Conclusion: Correct breastfeeding initiation time among respondents is low. Planned pregnancy, pre-pregnancy decision on infant feeding option before pregnancy, primiparity, vaginal delivery and breast milk as first food given to the neonate after delivery were associated with having correct breastfeeding initiation time among respondents. Efforts should be made to complement Baby Friendly Hospital Initiative with baby friendly community initiative in order to improve the rate of correct breastfeeding initiation time in our setting.

Effect of phenophase based irrigation schedules on growth, yield and quality of baby corn (Zea mays L.)

The field experiment was conduced at the Agronomy Field Unit, Main Research Station, University of Agricultural Sciences, Hebbal, Bangalore, India during 2002 and 2003 to study the effect of irrigation schedules on growth, yield and quality of baby corn. The soil of the experimental site was red sandy loam in texture with neutral reaction. The experiment was laid out in a randomized complete block design with three replications. There were seven treatments of irrigation schedules based on IW/CPE ratio of 0.6 and 1.0 during different phenophases of baby corn. The results of the experiment revealed that the baby corn dry matter was significantly higher (75.57 g.plant–1) with higher green fodder yield of 43.47 t.ha–1 due to irrigation scheduled at IW/CPE ratio of 1.0 followed by moisture stress at early stage (I3). Irrigations scheduled at IW/CPE ratio of 1.0 registered significantly higher baby corn yield of 6.60 t.ha–1 followed by the delayed irrigation at early stage of 10 - 25 DAS. Significantly higher crude protein, phosphorus, potassium and lower reducing sugars and ascorbic acid content of baby corn was recorded under IW/CPE ratio of 1.0. Delayed irrigation at 0.6 IW/CPE ratio through-out produced baby corn with higher taste and juiciness. The total crop water use ranged from 294.10 to 469.10 mm, respectively under continuously delayed irrigation at 0.6 IW/CPE ratio and frequent irrigation at IW/CPE ratio of 1.0 which also recorded higher water use efficiency.

Natural Formulations Addressing Skin Challenges in Baby Care

Addressing skin challenges in baby care formulations is quite a challenge itself, as the formulation not only needs to be active, but it should also meet specific requirements in terms of ingredients, agreability and rational of the formulation design. Object of this study was the realization of a few different cosmetic formulations blending soundly documented natural active ingredients in systems matching the most common requirements of the baby care products. Additionaly, compatibility evidences of the employed natural actives within the tested systems have also been observed. We are therefore presenting the formulation design of four different formulations for baby care: a baby wash, an immediate rash recovery, an after sun emulsion and a calming and soothing product, each one described for the rational of the actives it contains and provided with a detailed formulation design. Specific attention will be directed to those ingredients for which clinical data supporting the expected skin benefits are available.
