The Effects of Pigs' Feet Consumption on Lactation

Pigs' feet are traditionally consumed by Korean women to increase milk production during lactation. In this study, we evaluated the perceived effectiveness and safety of consuming pigs' feet. Parous women were recruited to complete survey questionnaires in South Korea. Of the 516 respondents, 188 (36%) claimed they consumed pigs' feet. One-hundred twenty women (64%) who consumed pigs' feet reported experiencing an increase in breast milk production. Seventy-three (61%) women from this same group exclusively breastfed. In contrast, 16 (25%) of 65 respondents who did not embrace the same purported effect of pigs' feet indicated that they solely breastfed. Ninety-eight (82%) respondents who consumed pigs' feet and reported galactagoguic effects would recommend its use. Study findings reveal that the majority of women who consume pigs' feet believe in its milk-promoting effects. The results of this study suggest that further investigation of the galactagoguic effects of pigs' feet via conduction of an experimental study is warranted.
Comparison of fattening performance, carcass characteristics, and egg quality characteristics of Japanese quails with different feather colors

The objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old quail chicks with 4 different feather colors were used as animal material. Quails were fed ad libitum for 42 days to determine fattening performance and carcass traits. To determine egg traits, 48 hens from each group, in a total of 192, were selected and caged according to feather color. Eggs were collected for four consecutive weeks and egg quality characteristics were measured. Different feather colors had a significant effect on live weight, feed intake, feed conversion ratio, and carcass characteristics. Significant differences between the groups were detected for egg weight, specific gravity, shape index, shell weight, albumen weight, yolk weight, albumen index, and yolk index. Japanese quails with all four feather colors can be reared depending on the choice. However, due to lower feed conversion ratio, white-feathered quails may be preferred for meat production purposes. Color variations should be considered when selecting quails.
Beryllium inhibition of regeneration. I. Morphological effects of beryllium on amputated fore limbs of larval Amblystoma

The analysis of regeneration phenomena in the Amphibia has been greatly facilitated by the use of two general experimental methods : surgical operations performed on the regenerating structures, and coiitrolled applications of physical and chemical agents. The results derived by the former method in particular led to the elucidation of principles of broad significance, relating the causal factors operative in regeneration with those of embryonic development (see Weiss, '39; J. Needham, '42). In recent years the use of abnormal physical and chemical environments as analytical tools for the study of regenerating organs has resulted in the uncovering of important and unique causal relationships which had eluded analysis by the more widely used surgical methods. For example, the delicate balance between regression and differentiation phenomena in the early phases of regeneration in the urodele limb was first made clear with the aid of x-radiation (Butler, '31, '33; Butler and Puckett, '40). I t is surprising that in regeneration studies more use has not been made of chemical agents which have known effects in disengaging developmental processes in embryos, particularly since regenerating amphibian limb and tail tissues
Health-related quality of life in paediatric asthma: Children’s and parents’ perspectives

This study aimed to describe the quality of life of a group of Portuguese children with asthma, to explore the association between health-related quality of life (HRQL), asthma severity, child’s characteristics and parental psychopathology. Additionally, the concordance between the children’s HRQL self-report and the parents’ HRQL proxy was assessed. Fifty children with asthma (7–13 years) and their primary caregiver participated in the study by filling out the DISABKIDS-37 and other self-report questionnaires. Results for the DISABKIDS-37 supported a good internal consistency and associations between the facets and the global score, in the two versions of the questionnaire. Children and their caregivers scored the child’s HRQL positively. Parents of children with an asthma diagnosis for a longer period reported better HRQL. The distribution of the HRQL scores in the child’s version showed differences across categories of subjective severity rated by children and across categories of asthma control assessed by the physician. The group with uncontrolled asthma obtained lower HRQL scores than the other groups. There was a lack of convergence between self-report and parent’s report of HRQL, with the exception of the physical limitation facet. Asthma severity assessed by the child and parental psychopathology explained 28% of the variance in the children’s self-rated HRQL. Findings reinforce that children and caregivers’ reports are complementary to each other and support the recommendation to use both information sources.
Block periodization versus traditional periodization in trained cross-country skiers and biathletes

AbstractThe purpose of this study was to compare the effect of two different methods of organizing endurance training in trained male and female cross-country skiers and biathletes during a 5-week preparation period.MethodOne group of athletes performed block periodization (BP; n=10), wherein week 1 and 3 constituted of respectively five and three sessions of high intensity aerobic training (HIT), followed by respectively one and two weeks of one weekly HIT session. Another group performed a more traditional organization (TRAD; n=9), with four weeks of two HIT sessions and one week of three HIT sessions. The HIT was interspersed with low intensity training (LIT) so that similar total volumes of both HIT and LIT were performed in the two groups. The majority of the both HIT and LIT were performed on roller skis. All tests were conducted skating on roller ski treadmill.ResultsBP achieved an improvement in maximal oxygen consumption (VO2max), while TRAD did not improve (BP; 2.0 ± 2.5% (p = 0.05), TRAD; –0.1 ± 3.0% (p = 0.75). Also in maximal power output (Wmax) BP achieved an improvement, while TRAD did not improve (BP; 3.8 ± 4.3% (p = 0.016), TRAD; –2.5 ± 6.6% (p = 0.241). Mean effect size (ES) of the relative improvement in VO 2max (ES: 0.76) and Wmax (ES: 1.11) revealed moderate superior effects of BP compared to TRAD.ConclusionThe present study suggests that block periodization of endurance training have superior effects on VO 2max and Wmax compared to traditional organization.
Medium Term Follow up of the Biodynamic Neck Sparing Prosthesis

Hip resurfacing (HR) and neck sparing prostheses (NSP) have been advocated for the treatment of arthritis in younger patients. Some complications following HR have been documented in the recent literature, but NSP are not yet supported by clinical follow-up studies of sufficient duration. We present an assessment of the neck sparing “Biodynamic” prosthesis. 153 patients were evaluated in a longitudinal cohort prospective study, with survival analysis, clinical score and radiographic assessment of stability and osteointegration at 41.8 months average follow up. Survival and clinical outcome were similar to most traditional prostheses in the literature. On radiographic analysis we recorded good neck preservation and osteointegration. Only two stem failures were recorded. Poor clinical outcome was related to misalignment of prostheses implanted during the ‘learning curve’. The NSP system described may be a good alternative to HR for younger patients. The system is characterized by good survival and clinical and radiographic outcome combined with bone stock preservation.
A 200 MHz 7th-order equiripple continuous-time filter by design of nonlinearity suppression in 0.25 /spl mu/m CMOS process

7th order equiripple filter with cutoff frequency of 200 MHz is developed in a 0.25 /spl mu/m CMOS process. A new design method has been adopted to obtain enough accuracy and linearity in high frequency operation. Optimal device sizes are determined that maximize the accuracy. The most suitable filter configuration is determined that suppresses the nonlinearity of the transconductors. Experimental results satisfy group delay variation of /spl plusmn/5% and THD of less than 1% for a 400 mVpp differential input.
Switching Rule Design for Switched Dynamic Systems With Affine Vector Fields

In this paper, we propose a method for designing switching rules that drive the state of the switched dynamic system to a desired equilibrium point. The method deals with the class of switched systems where each mode of operation is represented by a dynamical system with an affine vector field. The results are given in terms of linear matrix inequalities and they guarantee global asymptotic stability of the tracking error dynamics. Switching rules based on complete and partial state measurements are proposed. The case of uncertain polytopic systems is also considered and a numerical example illustrates the approach.
Association of early caffeine administration and neonatal outcomes in very preterm neonates.

IMPORTANCE Advantages of caffeine for apnea of prematurity have prompted clinicians to use it prophylactically even before apnea. OBJECTIVE To determine the effect of early initiation of caffeine therapy on neonatal outcomes in very preterm infants born in Canada. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study was conducted. Patients included preterm neonates born at less than 31 weeks' gestation admitted to 29 participating Canadian Neonatal Network neonatal intensive care units between January 1, 2010, and December 31, 2012. EXPOSURES Neonates who received caffeine were divided into 2 groups based on the following timing of caffeine initiation: within the first 2 days after birth (early) and on or after the third day following birth (late). MAIN OUTCOME AND MEASURE A composite of death or bronchopulmonary dysplasia. RESULTS Of 5517 eligible neonates, 5101 (92.5%) received caffeine (early: 3806 [74.6%]; late: 1295 [25.4%]). There was no difference in weight or gestational age at birth between the groups. Neonates in the early group had decreased odds of a composite outcome of death or bronchopulmonary dysplasia (adjusted odds ratio [AOR], 0.81; 95% CI, 0.67-0.98) and patent ductus arteriosus (AOR, 0.74; 95% CI, 0.62-0.89). There was no difference between the groups in mortality (AOR, 0.98; 95% CI, 0.70-1.37), necrotizing enterocolitis (AOR, 0.88; 95% CI, 0.65-1.20), severe neurological injury (AOR, 0.80; 95% CI, 0.63-1.01), or severe retinopathy of prematurity (AOR, 0.78; 95% CI, 0.56-1.10). CONCLUSIONS AND RELEVANCE In very preterm neonates, early (prophylactic) caffeine use was associated with a reduction in the rates of death or bronchopulmonary dysplasia and patent ductus arteriosus. No adverse impact on any other outcomes was observed.
AIDS-related CNS cryptococcosis: radiologic-pathologic correlation.

PURPOSE This study evaluates the effectiveness of cranial CT and MR in detecting autopsy findings of AIDS-related CNS cryptococcosis. METHODS Final imaging studies compared with pathology were CT in eight patients (five with contrast) and MR in five patients (all with Gd-DTPA). RESULTS Neither modality effectively identified cryptococcal meningitis. Punctate hyperintensities were seen in all patients with MR and corresponded pathologically to both perivascular spaces dilated by cryptococcal infection and cryptococcomas. Pathologically, cryptococcomas were more common than dilated perivascular spaces. MR detected more cryptococcomas than did CT, but both modalities underestimated the number of lesions seen at autopsy. Contrast enhancement of cryptococcomas and cryptococcal meningitis was uncommon. CONCLUSIONS CNS cryptococcosis was more effectively demonstrated by MR than by CT, but both modalities underestimated the pathologic extent of the disease. Cryptococcal lesion contrast enhancement was unusual possibly because of the immunocompromised state of our patients and the unique characteristics of the organism itself.
Recruiting large online samples in the United States and India: Facebook, Mechanical Turk, and Qualtrics

Abstract This article examines online recruitment via Facebook, Mechanical Turk (MTurk), and Qualtrics panels in India and the United States. It compares over 7300 respondents—1000 or more from each source and country—to nationally representative benchmarks in terms of demographics, political attitudes and knowledge, cooperation, and experimental replication. In the United States, MTurk offers the cheapest and fastest recruitment, Qualtrics is most demographically and politically representative, and Facebook facilitates targeted sampling. The India samples look much less like the population, though Facebook offers broad geographical coverage. We find online convenience samples often provide valid inferences into how partisanship moderates treatment effects. Yet they are typically unrepresentative on such political variables, which has implications for the external validity of sample average treatment effects.
Plastic Phenotypic Response to Light of 16 Congeneric Shrubs From a Panamanian Rainforest

The comparative phenotypic plasticity of 16 species of tropical rainforest shrubs (genus Psychotria, Rubiaceae) was investigated by growing plants in three light environments on Barro Colorado Island (BCI, Panama). The three light environments gave daily photon flux densities (PPFD) similar to the natural light gradient from shaded forest understory to small and large canopy gaps. Six of the species are principally found in gaps or forest edge environments, whereas the other ten species are principally found in shaded understories. Interactions between light treatment and species resulted in unpredictable mean phenotypic expression across light treatments. Shoot relative growth rates (RGR) were similar for understory and gap species in the low light treatment. Gap species had significantly greater shoot RGR in the intermediate light treatment than in the high light treatment. Mean plasticity was significantly lower for morphological variables when com- pared to physiological variables, while variation in plasticity was significantly greater for structural variables. Significant differences between gap and understory species were found in the plasticity of six out of the seven variables. The mean phenotypic plasticity of the seven variables was significantly greater for gap than for understory species. The high plasticity of gap species was consistent with the hypothesis that specialization in a more favorable environment increases plasticity. The species exhibited a wide range of leaf longevities, from four to 29 months, with gap species having, on average, shorter leaf life- span than understory species. Mean phenotypic plasticity decreased with increasing leaf longevity. Selection for greater plasticity may be stronger in the gap species because gaps exhibit a relatively predictable decrease in PPFD for which plasticity could be adaptive. While we have found a significant correlation between phenotypic plasticity and habitat affiliation, phylogeny (subgenus ascription) was not correlated with plasticity or with plant performance in any given PPFD treatment, reinforcing the hypothesis that phenotypic plas- ticity has evolved through natural selection in this diverse genus.
Radio Frequency Self-Interference Cancellation With Analog Least Mean-Square Loop

A multitap adaptive filter with analog least mean-square (ALMS) loop is proposed in this paper for effective and low complexity self-interference cancellation implemented as part of the radio frequency frontend in a full duplex transceiver. Comprehensive analyses of the ALMS loop’s behaviors at both micro and macroscales are presented for a wireless communication system with single carrier signaling. It is revealed that there is always an irreducible residual interference due to the cyclostationary property of the transmitted signal. The interference suppression ratio (ISR) lower bound is derived accordingly, which can be used as a design rule for determining the ALMS loop parameter. Stationary analysis shows that the convergence speed and achievable ISR of the ALMS loop are determined by the loop gain and the autocorrelation function of the transmitted signal. The interference channel modeling error with the adaptive filter also accounts for part of the residual interference power. These theoretical findings are verified by simulation and experimental results.
Utilizing Exposure , Relaxation , and Rescripting Therapy : Impact on Nightmares , Sleep Quality , and Psychological Distress

Experiencing a traumatic event may initiate or exacerbate the occurrence of nightmares. Nightmares may impact sleep quality and quantity, posttraumatic stress symptoms, and depression. Recently, imagery rehearsal has gained attention in the treatment of trauma-related nightmares and is reported to be promising in the reduction of nightmares. On the basis of the vast literature describing the therapeutic benefits of exposure techniques for anxiety-related problems, the treatment was modified to enhance the exposure component. This article presents a case series using this modified version of imagery rehearsal, Exposure, Relaxation, and Rescripting Therapy, with 1 male and 3 female participants. Overall, the participants treated reported a reduction in nightmare frequency and severity; 3 out of 4 participants also reported a reduction in posttraumatic stress and depression symptomotology and an increase in sleep quality and quantity. Clinical implications and future research directions are discussed.
The Politics of Judicial Economy at the World Trade Organization

Abstract International institutions often moderate the legal decisions they render. World Trade Organization (WTO) panels do this by exercising judicial economy. This practice, which is evident in 41 percent of all rulings, involves the decision not to rule on some of the litigants' arguments. The constraint is that it can be appealed. We argue that panels exercise judicial economy when the wider membership is ambivalent about the future consequences of a broader ruling. This is proxied by the “mixed” (that is, nonpartisan) third-party submissions, which are informative because they are costly, jeopardizing a more decisive legal victory that would benefit these governments too. We empirically test this hypothesis, and find that mixed third-party submissions increase the odds of judicial economy by upwards of 68 percent. This suggests that panels invoke judicial economy to politically appease the wider WTO membership, and not just to gain the litigants' compliance in the case at hand.
Interleukin 22 Receptor 1 Expression in Pancreas Islets

Objectives: Interleukin (IL) 22 is a recently identified T-cell-derived cytokine. IL-22 binds at the cell surface to a heterodimer receptor complex composed of IL-22 receptor (R) 1 and IL-10R2. In this study, we performed immunohistochemical analyses for IL-22R1 expression in human pancreatic tissue. Methods: Normal human pancreatic tissue (n = 8) was immunostained with antihuman IL-22R1 antibodies following standard immunohistochemical procedures. Results: In the normal human pancreas, IL-22R1 was expressed in the islets of Langerhans. IL-22R1 was not expressed by the acinar cells and ductal epithelium. Double-immunostaining experiments showed that the majority of insulin-expressing &bgr; cells and glucagon-expressing &agr; cells were immunopositive for IL-22R1. Conclusions: The islets of Langerhans are the local site for IL-22R1 expression in the human pancreas. It may be that the T-cell-mediated immune response modulates cell islet function through IL-22 signaling.
SEASONAL VARIATIONS OF PHOTOSYNTHETIC PIGMENTS, TOTAL C, N, AND P CONTENT, AND PHOTOSYNTHESIS IN PHYLLARIOPSIS PURPURASCENS: (PHAEOPHYTA) FROM THE STRAIT OF GIBRALTAR

Photosynthetic pigments, C, N, and P tissue composition, and photosynthetic rate were measured from April to October in the brown alga Phyllariopsis purpurascens (C. Agardh) Henry et South (Laminariales, Phaeophyta) growing at a 30‐m depth in the Strait of Gibraltar. Ir‐radiance reaching the population ranged from 13.5 to 27.5 mol.m‐2.mo‐1. The available light for this species, expressed as a percentage of the irradiance above the water, was 1.8%. Dissolved inorganic nitrogen forms, NO3‐and NH4+, were constant from April to October, whereas phosphate was depleted in August. Chlorophyll a decreased from 520.0 ± 165.0 to 199.6 ± 159.9 μg. g‐1 dry weight; in contrast, chlorophyll c and carotenoids did not change until September but increased threefold in October. C:N and N:P ratios changed in the same way and in the same range. They were constant until July but increased from 15–17 up to 42 (C:N) and from 14 to 40 (N:P) in October, suggesting a severe P limitation of growth of this species. The dark respiration rate and the light compensation point were constant from April to October (0.5 ± 0.1 μmol O2. m‐2.s‐1 and 6.5 ± 0.2 μmol.m‐2. s‐1, respectively), whereas the maximum rate of apparent photosynthesis, light onset saturation parameter, and half saturation constant for light were maximum in April to May (3.7 μmol O2. m‐2.s‐1and 40 and 41.5 μmol.m‐2. s‐1, respectively) and October (3.6 μmol O2. m‐2.s‐1 and 50 and 53.7 μmol.m‐2. s‐1, respectively). They were minimum in August (1.2 μmol O2.m‐2.s‐1 and 11.3 and 12 μmol.m‐2.s‐1, respectively). These minimum figures yielded a negative carbon budget in August and 0 in September, whereas it was positive the rest of the year. Photosynthetic efficiency, estimated by the ratio between maximum apparent photosynthesis and light half saturation constant, showed a strong agreement with productivity measured by means of an independent method. These results indicate that lamina expansion in this species is controlled by photosynthetic efficiency.
Supplementation with vitamin E but not beta-carotene in vivo protects low density lipoprotein from lipid peroxidation in vitro. Effect of cigarette smoking.

Several lines of evidence suggest that oxidatively modified low density lipoprotein (LDL) is atherogenic and that antioxidants may protect LDL against oxidation. In addition, cigarette smoking is known to induce oxidant stress. We have examined the effect of ingestion of the antioxidants D,L-alpha-tocopherol (vitamin E) and beta-carotene and of smoking on the resistance of LDL against copper-mediated oxidation. Six healthy nonsmoking volunteers ingested 1,000 IU/day D,L-alpha-tocopherol acetate for 7 days. After vitamin E ingestion concentrations of alpha-tocopherol in plasma and LDL increased 3.0- and 2.4-fold, respectively. Simultaneously, the oxidation resistance of LDL was elevated significantly (+41%), and the rate of oxidation was decreased significantly (-19%). The increase in alpha-tocopherol content of LDL and the increase in resistance time were highly correlated (rs = 0.89, p = 0.014). Eight weeks after termination of the vitamin E intake, alpha-tocopherol concentrations in plasma and LDL and oxidation resistance of LDL had returned to baseline values. In smokers (n = 46), plasma levels of vitamin C (-26%) and concentrations of beta-carotene (-44%, -43%) and total carotenoids (-23%, -29%) in plasma and LDL, respectively, were significantly lower compared with nonsmokers (n = 23). No differences were found in alpha-tocopherol content of LDL and the susceptibility of LDL to lipid peroxidation in both groups. Supplementation of a group of smokers in a 14-week randomized, double-blind, placebo-controlled intervention trial with beta-carotene resulted in a 16.6- and 5.0-fold increase of LDL beta-carotene and total carotenoid content, respectively.
