Abstract
1. This study investigated the effect of dietary calcium (Ca) levels on growth performance, bone development and Ca transporter gene expression levels in the small intestine of broiler chickens.2. On the day of hatch, 350, Ross 308 male broilers were randomly allotted to one of five treatments with five replicate pens each and 14 birds per pen. Dietary Ca levels in feed were 5.0, 7.0, 9.0, 11.0 and 13.0 g/kg, in which 9.0 g/kg was in the control diet. All diets contained 4.5 g/kg non-phytate phosphorus (NPP).3. The increase in dietary Ca levels from 5.0 to 13.0 g/kg did not affect the growth performance of 1- to 18-day-old broilers (P > 0.05).4. Increasing the Ca levels linearly increased the ash weight and the contents of ash, Ca and phosphorus (P) in the tibia of broilers at 18 days of age (P < 0.05). The contents of ash, Ca and P in broilers fed with 9.0 g/kg Ca were higher than those in birds fed with 5.0 g/kg Ca (P < 0.05).5. Increasing the Ca levels linearly decreased mRNA expression levels of the Ca-binding protein 28-kDa (CaBP-D28k), plasma membrane Ca-transporting ATPase 1b (PMCAlb), sodium (Na)/Ca exchanger 1 (NCX1), nuclear vitamin D receptor (nVDR) and membrane vitamin D receptor (mVDR) in the duodenum of broilers at 18 d of age (P < 0.05). Similar results were seen in the jejunum and ileum. Broilers fed 9.0-13.0 g/kg Ca in feed had lower mRNA expression levels of CaBP-D28k and PMCAlb in the small intestine than birds fed 5.0 g/kg Ca in feed (P < 0.05).6. The data indicated that low levels of dietary Ca stimulated its transporter gene transcription and promoted absorption, but high levels of Ca inhibited transporter gene expression and prevented excessive absorption in the small intestine of broiler chickens.

Abstract
First-principles calculation and Boltzmann transport theory have been combined to comparatively investigate the band structure, phonon spectrum, lattice thermal conductivity, electronic transport property, Seebeck coefficient, and figure of merit of square/octagon (s/o)-bismuth monolayer. Calculations reveal that the thermoelectric properties of s/o-bismuth monolayer are better than that of β-bismuth monolayer, which should be mainly due to the low lattice thermal conductivity and weakened coupling of electrons and phonons. It is also found that the phonon frequency and group velocity could play dominant roles in determining the magnitude of the lattice thermal conductivity of s/o-bismuth monolayer. Furthermore, the Seebeck coefficient and figure of merit of s/o-bismuth monolayer are higher than those of β-bismuth monolayer. The derived results are in good agreement with other theoretical results in the literature, and could provide a deep understanding of thermoelectric properties of the bismuth monolayer materials.

Abstract
Abstract
Background and objectives
Retrograde flow (RF) in the aortic isthmus is frequently observed in fetuses in various hemodynamic states including congenital heart defects (CHD). This study sought to: 1) establish the association between this observation and variables of CHD by fetal echocardiography (FE); and 2) to computer flow dynamic (CFD) model to probe the causes and mechanisms underlying this observation.
Methods
A total of 256 (gestational age (GA) 26.3±9.8 weeks) fetuses with CHD and 168 (GA: 25.8±10.3weeks) with normal FE were examined from January, 2011 to May, 2016. The study group was divided into: 1) no RF, 2) end systolic RF, end diastolic RF, systolic RF, diastolic RF, and systolic and diastolic RF sub-groups (Figure upper). GA, cerebroplacental ratio (CPR) of pulsatility index (PI) in middle cerebral and umbilical arteries, cardiothoracic area ratio (CTR), left and right atrial dimensions (LA/RA), left and right ventricular dimensions (LV/RV), aortic and pulmonary artery dimensions (AO/PA), and aortic isthmus and ductal arch dimensions (AI/DA), velocity ratio of aorta and pulmonary artery (AO/PAv), aortic isthmus and ductal arch in systolic (AI/DAvs) and diastolic (AI/DAvd). Using principal component analysis (PCA), the component score coefficient matrix and optional variance percent (OVP) was calculated by PCA and the RF pattern was simulated by CFD (Figure lower).
Results
RF modeling by CFD was feasible (Figure B). Component analysis by PCA showed that four types of variables were associated with RF: 1) Structural variables contribute 23.7% OVP, including LV/RV, LA/ RA, AO/PA, and IS/DA; 2) Resistance variables 16.8% OVP, i.e. CPR; 3) Growth variables 12.2% OVP, i,e, GA and CTR; and 4) Velocity variables 10.9% OVP, i.e. AO/PAv, AI/DAvd.
Retrograde flow by fetal echo and CFD
Conclusions
Retrograde flow in the aortic isthmus is associated with structural, resistance, growth, and velocity variables in fetal circulation in various CHD and normal 3rd trimester pregnancies. Simulation and modeling by CFD is feasible and may be useful to understand the causes and mechanisms of retrograde flow and its utility in diagnosis and prognosis in CHD.

Abstract
Objective: To explore the value of the intraoperative transesophageal echocardiography during the aortic valve reconstruction. Methods: The echocardiographic features were retrospectively summarized in 19 patients (male: 15 cases; female: 4 cases; age ranged from 12 to 65 years, mean age: 37.7 years) with aortic valve reconstruction at Beijing Anzhen Hospital between October 2014 and October 2016. Results: The findings of the neo-aortic valve on the transesophageal echocardiography included the slightly thickened and hyperechogenicity of the commission, especially the central coaptation point of the neo-valve. Trace aortic regurgitation was noted in 9 cases after operation, mild aortic regurgitation in 1 case and no aortic regurgitation in 9 cases. The velocity of the aortic valve increased significantly in 2 cases. Compared with pre-operation, the diameter of ascending aorta[(32.7±6.1) mm vs (36.4±6.3) mm, P<0.001]and the inner diameter of left ventricle[(48.3±6.1) mm vs (59.1±7.3) mm, P<0.001]decreased significantly after operation, the coaptation length of aortic valve[(6.6±1.3) mm vs (2.2±0.7) mm, P<0.001]significantly increased than that of pre-operation. The mean immediate velocity after operation (175 cm/s) was slightly higher than that (165 cm/s) of 3-month follow-up after surgery, but with no significant difference (P=0.367). Severe aortic regurgitation was found 15 days after operation in 1 case and 12 months after operation in 2 cases. Conclusion: Intraoperative transesophageal echocardiography is a useful tool to evaluate the result of the aortic valve reconstruction.

Abstract
First-principles calculations and Boltzmann transport theory have been combined to comparatively investigate the band structure, phonon spectrum, lattice thermal conductivity, electronic transport properties, Seebeck coefficients, and figure of merit of the β-bismuth monolayer and bulk Bi. Calculation reveals that low dimensionality can bring about the semimetal-semiconductor transition, decrease the lattice thermal conductivity, and increase the Seebeck coefficient of Bi. The relaxation time of electrons and holes is calculated according to the deformation potential theory, and is found to be more accurate than those reported in the literature. It is also shown that compared with Bi bulk, the β-bismuth monolayer possesses much lower electrical conductivity and electric thermal conductivity, while its figure of merit seems much bigger. The derived results are in good agreement with experimental results in the literature, and could provide a deep understanding of various properties of the β-bismuth monolayer. First-principles calculations and Boltzmann transport theory have been combined to comparatively investigate the band structure, phonon spectrum, lattice thermal conductivity, and the transport properties of the β-bismuth monolayer and bulk Bi.![]()

Abstract
First principles calculation and Boltzmann transport theory have been used to reveal the effects of trigonal deformation on electronic structure and thermoelectric properties of bulk bismuth. It is found that the semimetal-semiconductor transition would happen at the critical c/a points of 2.41 and 2.51, and that such a transition should be ascribed to the opposite changes of band edges at T and L points during trigonal deformation. Calculations also reveal that trigonal deformation has an important effect on various temperature-dependent thermoelectric properties, and that carrier density plays a decisive role in determining the magnitude of Seebeck coefficient and figure of merit. The semimetal → semiconductor transition as a result of trigonal compression with the decrease of c/a fundamentally induces the best performance of the thermoelectric properties of bismuth at the c/a ratio of 2.45. The present results agree well with experimental observations in the literature, and provide a deep understanding of the intrinsic relationship between trigonal deformation, band structure, and thermoelectric properties of bismuth.

Abstract
This study was conducted to evaluate the relative biological value (RBV) of 1α-hydroxycholecalciferol (1α-OH-D3) to 25-hydroxycholecalciferol (25-OH-D3) in one- to 21-day-old broiler chickens fed calcium (Ca)- and phosphorus (P)-deficient diets. On the d of hatch, 450 male Ross 308 broiler chickens were weighed and randomly allotted to 9 treatments with 5 replicates of 10 birds per replicate. The basal diet contained 0.50% Ca and 0.25% non-phytate phosphorus (NPP) but was not supplemented with cholecalciferol (vitamin D3). The levels of Ca and NPP in basal diets were lower than those recommended by NRC (1994). 25-OH-D3 was fed at zero, 1.25, 2.5, 5.0, and 10.0 μg/kg, and 1α-OH-D3 was fed at 0.625, 1.25, 2.5, and 5.0 μg/kg. The RBV of 1α-OH-D3 to 25-OH-D3 based on vitamin D intake was determined by the slope ratio method. Results showed that 25-OH-D3 or 1α-OH-D3 improved the growth performance and decreased the mortality in one- to 21-day-old broilers. A linear relationship was observed between the level of 25-OH-D3 or 1α-OH-D3 and mineralization of the femur, tibia, or metatarsus. The RBV of 1α-OH-D3 to 25-OH-D3 were 234, 253, and 202% when the weight, ash weight, and Ca percentage of femur were used as criteria. The corresponding RBV of 1α-OH-D3 to 25-OH-D3 were 232 to 263% and 245 to 267%, respectively, when tibia and metatarsus mineralization were used as criteria. These data indicate that when directly feeding a hormonally active form of vitamin D as 1α-OH-D3 proportionally less is needed than when using the precursor (25-OH-D3) in diets deficient in Ca and P.

Abstract
1α-Hydroxycholecalciferol (1α-OH-D3) is a vitamin D derivative. The objective of this study was to evaluate the effects of 1α-OH-D3 on the growth and the mRNA expression of vitamin D receptor (VDR) in the small intestine and kidney of chickens. A total of 240 males of one-day-old Ross 308 broilers was randomly assigned to 4 treatments with 5 replicates of 12 birds per replicate. Three levels of 1α-OH-D3 (1.25, 2.5, and 5 μg/kg) were added to a basal diet containing 0.50% calcium (Ca), 0.25% non-phytate phosphorus (NPP), and without supplemental cholecalciferol (vitamin D3). The control diet contained 1.00% Ca, 0.45% NPP, and 25 μg/kg cholecalciferol. Dietary 1α-OH-D3 levels linearly improved the average daily feed intake (ADFI), average daily gain (ADG), femur and tibia mineralization, and plasma Ca concentration, and retained Ca and total phosphorus (tP) amounts in broilers from 1 to 21 d of age (P < 0.05). In addition, 1α-OH-D3 also linearly up-regulated the mRNA expression levels of VDR in the duodenum as well as those of VDR and sodium-phosphate cotransporter NaPi-IIa and NaPi-IIc in the kidney of broilers (P < 0.05). However, 1α-OH-D3 did not affect the mRNA levels of 25-hydroxylase in the liver or NaPi-IIb in the duodenum (P > 0.05). No differences were observed in the ADFI, ADG, bone length, plasma mineral concentration, retained tP amount, or the mRNA levels of the above genes (except for VDR in the kidney) between the birds fed the diet with 5 μg/kg 1α-OH-D3 and the birds fed the control diet (P > 0.05). By contrast, the weight, ash weight, ash percentage, and Ca percentage of the bone, retained Ca amount, and the mRNA level of VDR in the kidney were lower in the birds fed the diet with 5 μg/kg 1α-OH-D3 than in the birds fed the control diet (P < 0.05). These data indicate that 1α-OH-D3 up-regulates the gene expression of VDR in the small intestine and kidney at the transcriptional level, thereby improving the growth performance and bone mineralization of broiler chickens from 1 to 21 d of age.

Abstract
Objective: To compare the early clinical effect of septal myectomy and percutaneous transluminal septal myocardial ablation (PTMSA) on the left ventricular outflow obstruction and the rate of complication in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 204 patients with HOCM who received septal reduction treatment were recruited. These patients were divided into two groups, surgery group (n=135) (65 patients with modified Morrow procedure, 70 patients with non-Morrow myomectomy) and PTMSA group (n=69). The baseline characteristics, disease status, other history of surgery and echocardiography parameters before and after septal reduction were collected, as well as the complication within 1 week after operation. Results: The mean age in surgery group was (46±14) years old, with 76 males (56.3%); mean age was (47±11) years old and with 51 males (73.9%) in PTMSA group. There was no significant difference in age, gender, the time of symptom and diagnosis, syncope, family history and atrial fibrillation between the two groups (all P>0.05). The proportion of mitral valve prolapse in the surgery group was higher than that in PTMSA group (75.8% vs 44.2%, P<0.05). Baseline left ventricular outflow tract (LVOT) gradient was comparable (82.7 mmHg in surgery group vs 77.7 mmHg in PTMSA group, P>0.05). The mean resting LVOT gradient after septal reduction therapy was lower (16.55 mmHg in surgery group, 26.68mmHg in PTMSA group) than that before operation, with lower gradient in surgery group (P<0.05). Compared with PTMSA group, the duration of hospitalization was longer in surgery group (P<0.05). There was similar rate of operation related complications in the two groups. Conclusions: Both septal reduction therapies can improve the LVOT obstruction, more significant in surgery group, but with longer hospital stay. The rate of operation related complication is similar in both groups.

Abstract
Objective: To observe the clinical outcome of intramyocardial dissecting hematoma (IDH) after acute myocardial infarction (MI). Methods: The clinical characteristics and outcomes of nine patients with IDH after acute MI in Beijing Anzhen Hospital from 2010 to 2014 were retrospectively assessed, and all the patients were followed up. Results: The mean age of nine IDH patients (7 males, 2 females) was (61±5) years. One patient was diagnosed as right ventricular IDH and died before surgery because of deteriorated cardiac and renal failure. Eight patients were diagnosed as left ventricular IDH, among whom 1 patient died of perioperative bleeding. The other 7 patients survived, among whom 5 cases were treated medically and 2 cases accepted surgical treatment. After 2-6 years of follow-up, the survived patients had no other complications. Conclusion: IDH after acute MI was a rare clinical event with a high mortality, and improvement of recognition of this rare condition may reduce its mortality, especially the right ventricular IDH.

The retracted article is: Han JC, Zhang YJ and Li XD (2015). Association between polymorphisms in the XRCC1 gene and the risk of non-small cell lung cancer. Genet. Mol. Res. 14: 12888-12893. The GMR editorial staff was alerted about this article (received on May 3, 2015; accepted on August 18, 2015) published on October 21, 2015 (DOI: 10.4238/2015.October.21.9) that was found to be substantially similar to the publication of "Association of XRCC1 gene polymorphisms with risk of non-small cell lung cancer" (received on January 25, 2015; accepted on March 23, 2015; e-published on April 1, 2015) by Kang et al., published in the International Journal of Clinical Experimental Pathology 8 (4): 4171-4176. The authors were aware of the Kang et al.'s paper, since they cite it several times in the manuscript published in GMR. Some of the language is similar between the two manuscripts, but what is the most concerning is that several of the tables in the papers are nearly identical. Tables 2 and 3 are exactly identical between the two articles, suggesting that the publication in GMR was plagiarized from the publication in the International Journal of Clinical Experimental Pathology. The Publisher and Editor decided to retract these articles in accordance with the recommendations of the Committee on Publication Ethics (COPE). After a thorough investigation, we have strong reason to believe that the peer review process was failure and, after review and contacting the authors, the editors of Genetics and Molecular Research decided to retract the article. The authors and their institutions were advised of this serious breach of ethics.

Abstract
In this study, we analyzed the association between serum leptin levels and non-small cell lung carcinoma (NSCLC). By examining English and Chinese databases, we identified potential relevant studies for statistical analysis. Human-associated case-control studies evaluating the association between serum leptin levels and NSCLC according to the random-effect model were retrieved and extracted data were statistically analyzed. We identified 7 case-control studies evaluating the correlation between serum leptin levels and NSCLC, which included 705 subjects (390 NSCLC patients and 315 healthy participants). Negative associations were investigated between serum leptin levels and NSCLC [standardized mean difference (SMD) = 0.96, 95% confidence interval (CI) = 0.13-1.79, P = 0.023). Ethnicity-stratified analysis revealed there was no elevated leptin serum levels in NSCLC development in both Asians (SMD = 0.34, 95%CI = -0.10-0.79, P = 0.132) and Caucasians (SMD = 1.42, 95%CI = -0.09-2.93, P = 0.064). Sample size-stratified analysis of the association between serum leptin levels and NSCLC were found in studies of small sample size (SMD = 0.73, 95%CI = 0.04-1.41, P = 0.038), but not in studies of large sample size (SMD = 1.24, 95%CI = -0.52-3.01, P = 0.166). In the method-stratified subgroup analysis, serum leptin level was not correlated with NSCLC using a immunoradiometric assay method (SMD = 0.82, 95%CI = -1.38-3.03, P = 0.465). Determining the levels of the blood-based marker leptin may provide predictive information for NSCLC diagnosis.

Abstract
This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0.50% Ca and 0.25% non-phytate phosphorus (NPP) and was not supplemented with vitamin D. Vitamin D3 was fed at 0, 2.5, 5.0, 10.0, and 20.0 μg/kg, and 25-OH-D3 was fed at 1.25, 2.5, 5.0, and 10.0 μg/kg. The RBV of 25-OH-D3 was determined using vitamin D3 as the standard source by the slope ratio method. Vitamin D3 and 25-OH-D3 intake was used as the independent variable for regression analysis. The linear relationships between the level of vitamin D3 or 25-OH-D3 and body weight gain (BWG) and the weight, length, ash weight, and the percentage of ash, Ca, and P in femur, tibia, and metatarsus of broiler chickens were observed. Using BWG as the criterion, the RBV value of 25-OH-D3 to vitamin D3 was 1.85. Using the mineralization of the femur, tibia, and metatarsus as criteria, the RBV of 25-OH-D3 to vitamin D3 ranged from 1.82 to 2.45, 1.86 to 2.52, and 1.65 to 2.05, respectively. These data indicate that 25-OH-D3 is approximately 2.03 times as active as vitamin D3 in promoting growth performance and bone mineralization in broiler chicken diets.

Abstract
Numerous studies have evaluated the association between estrogen receptor alpha (ESR1) gene PvuII polymorphism and fracture risk in postmenopausal women. However, the results have been inconsistent. We performed a meta-analysis to examine the association between the ESR1 gene PvuII polymorphism and fracture risk in postmenopausal women. Studies published from PubMed, Google Scholar, and China National Knowledge Infrastructure data were retrieved. Pooled odds ratios with 95% confidence intervals were calculated using fixed- or random-effects models. A total of 6 case-control studies containing 592 patients and 705 controls were included in this meta-analysis. We found no association between the PvuII polymorphism in the ESR1 gene and fracture in postmenopausal women. Taking into account the effect of ethnicity, further stratified analyses were performed. In the subgroup analysis, no significant association was found in Caucasians and in Asians. No publication bias was found in the present study (all P > 0.05). In conclusion, the ESR1 gene PvuII polymorphism may not be associated with fracture risk in postmenopausal women. Additional larger studies are needed to confirm this conclusion.

Abstract
BACKGROUND/OBJECTIVES The forkhead factor Foxa3 is involved in the early transcriptional events controlling adipocyte differentiation and plays a critical function in fat depot expansion in response to high-fat diet regimens and during aging in mice. No studies to date have assessed the potential associations of genetic variants in FOXA3 with human metabolic outcomes. SUBJECTS/METHODS In this study, we sequenced FOXA3 in 392 children, adolescents and young adults selected from several cohorts of subjects recruited at the National Institute of Child Health and Human Development of the National Institutes of Health based on the availability of dual-energy X-ray absorptiometry data, magnetic resonance imaging scans and DNA samples. We assessed the association between variants present in these subjects and metabolic traits and performed in vitro functional analysis of two novel FOXA3 missense mutations identified. RESULTS Our analysis identified 14 novel variants and showed that the common single-nucleotide polymorphism (SNP) rs28666870 is significantly associated with greater body mass index, lean body mass and appendicular lean mass (P values 0.009, 0.010 and 0.013 respectively). In vitro functional studies showed increased adipogenic function for the FOXA3 missense mutations c.185C>T (p.Ser62Leu) and c.731C>T (p.Ala244Val) compared with FOXA3-WT. CONCLUSIONS Our study identified novel FOXA3 variants and mutations, assessed the adipogenic capacity of two novel missense alterations in vitro and demonstrated for the first time the associations between FOXA3 SNP rs28666870 with metabolic phenotypes in humans.

Abstract
OBJECTIVE This work aims to investigate the application of high definition flow imaging (HD-flow) in fetal hemodynamics, and establish reference range of hemodynamic parameters in fetal with different gestational ages. MATERIALS AND METHODS A thousand of normal pregnant women were divided into five groups: 18-22, 23-27, 28-32, 33-37, and 38-40 gestational weeks. Color Doppler flow imaging (CDFI) and HD-flow were adopted to display the heart structure and measure the blood flow velocity. The pulmonary vein display results were scored. The results of HD-flow and CDFI were compared. RESULTS The catheter peak velocity of fetal mitral, tricuspid, aortic, pulmonary artery, aortic arch, ductal arch, the inferior vena cava, pulmonary vein, and venous catheter increased continuously with the increase of gestational age, showing a linear correlation. HD-flow was superior to CDFI on the display of pulmonary vein in 18-22, 23-27, and 28-32 weeks (p < 0.05), but was not in 33-37 and 38-40 weeks. HD-flow was an accurate positioning method for the pulmonary veins. CONCLUSION HD-flow can make accurate evaluation of fetal hemodynamics and the demonstration of low blood flow, such as pulmonary venous, is better than CDFI. Pulmonary veins can be accurately positioned with HD-flow. HD-flow can demonstrate the main blood vessels of the whole fetal circulation and can display the spatial relationship of the blood vessels. It is of important clinical significance in hemodynamic study.

Abstract
Background In rodents, hypothalamic brain-derived neurotrophic factor (BDNF) expression appears to be regulated by melanocortin-4 receptor (MC4R) activity. The impact of MC4R genetic variation on circulating BDNF in humans is unknown. Objective To compare BDNF concentrations of subjects with loss-of-function (LOF) and gain-of-function (GOF) MC4R variants to those of controls with common sequence MC4R. Methods Circulating BDNF was measured in two cohorts with known MC4R sequence: 148 subjects of Pima Indian heritage ([mean±SD]: age 15.7±6.5y, BMI-Z 1.63±1.03), and 69 subjects of Hispanic heritage (10.8±3.6y, BMI-Z 1.57±1.07). MC4R variants were characterized in vitro by cell surface expression, receptor binding, and cAMP response after agonist administration. BDNF single nucleotide polymorphisms (SNPs) rs12291186, rs6265, and rs7124442 were also genotyped. Results In the Pima cohort, no significant differences in serum BDNF was observed for 43 LOF-subjects versus 65 LOF-matched controls [age-, sex-, and BMI-matched] (P=0.29), or 20 GOF-subjects versus 20 GOF-matched controls (P=0.40). Serum BDNF was significantly associated with genotype for BDNF rs12291186 (P=0.006) and rs6265 (P=0.009), but not rs7124442 (P=0.99); BDNF SNPs did not interact with MC4R status to predict serum BDNF. In the Hispanic cohort, plasma BDNF was not significantly different among 21 LOF-subjects, 20 GOF-subjects, and 28 controls (P=0.79); plasma BDNF was not predicted by BDNF genotype or BDNF-x-MC4R genotype interaction. Conclusions Circulating BDNF concentrations were not significantly associated with MC4R functional status, suggesting that peripheral BDNF does not directly reflect hypothalamic BDNF secretion and/or that MC4R signaling is not a significant regulator of the bulk of BDNF expression in humans.

Abstract
An experiment was conducted to evaluate the effects of one alpha-hydroxycholecalciferol (1α-OH D3) on growth performance, tibia quality, and skin and meat color in broilers fed calcium (Ca)- and phosphorus (P)-deficient corn-soybean meal diets. A total of 288 male Ross broilers, at 21 days of age, were randomly assigned to three treatments with eight cages per treatment. Three levels of 1α-OH D3 (0, 5, and 10 μg/kg) were added to a basal diet (0.50% Ca, 0.13% non-phytate phosphorus (NPP), and 0.35% total phosphorus (tP)) without vitamin D3. As a result of this study, the addition of 1α-OH D3 increased body weight gain (p<0.001), feed intake (p = 0.007), feed efficiency (p<0.001), tibia weight (p = 0.002), length (p<0.001), breaking-strength (p = 0.012), ash (p<0.001), Ca (p<0.001), and P content (p = 0.004). Dietary 1α-OH D3 enhanced breast meat yellowness (p = 0.015) and the length and weight of the small intestine of the broilers. Moreover, 1α-OH D3 decreased serum Ca concentration (p = 0.074) and breast meat redness (p = 0.010). These results indicate that the 1α-OH D3 improves growth, tibia quality, and meat color in broilers fed Ca- and P-deficient corn-soybean meal diets.

Abstract
A dilemma presents itself to the otoneurologist and neurosurgeon when determining the least invasive surgical approach to giant cholesterol cysts (GCC) of the petrous apex of the temporal bone. These lesions can be diagnosed with a fair degree of certainty with imaging studies. Transmastoid and subcochlear approaches may be inadequate to access these lesions, and the transcochlear approach results in the sacrifice of hearing. A minimally invasive, combined microscopic and endoscopic sublabial transsphenoid approach to drain and marsupalize these lesions has been chosen by the authors in those cases that are anatomically possible. The purpose of this article is to establish the feasibility of exenterating anterior petrous apex cells by way of this approach, and to better conceptualize the anatomy of the Spheno-Petro-Clival Complex (SPC). Ten Fresh cadaveric "whole head" specimens were dissected with, endoscopic/microscopic control, through midline, sublabial, transseptal, and transsphenoidal routes to the petrous apex. The three-dimensional relationships of the sphenoid sinus, petrous apex, and the clivus were further demonstrated by dissections of the same specimens from the posterior fossa. Sagittal cut sections were also performed. After confirming the feasibility of this approach by dissections, the technique was adopted for performing drainage of GCC of the petrous apex in clinical cases.

Abstract
This paper focuses on turbine blade internal cooling. Internal cooling is achieved by passing the coolant through several rib-enhanced serpentine passages inside the blade and extracting the heat from the outside of the blades. Both jet impingement and pin-fin-cooling are also used as a method of internal cooling. In the past number of years there has been considerable progress in turbine blade internal cooling research and this paper is limited to reviewing a few selected publications to reflect recent developments in turbine blade internal cooling.

Abstract
Cholesteatoma is a destructive process involving an accumulation of desquamated keratin arising from squamous epithelium that pathologically has invaded the middle ear or mastoid process. The clinical hallmarks of cholesteatomas, namely invasion of healthy tissues, migration, unrestrained proliferation, aggressiveness, recidivism, and uncoordinated differentiation predict the existence of defects in the normal biology and biochemistry of the cellular constituents that compose a cholesteatoma, as well as in the cellular interactions between these cells, the surrounding normal tissue, and the host. In the current report, we analyzed 11 cholesteatomas and matched healthy tissue for altered expression in four different cell surface peptidases, aminopeptidase A, aminopeptidase N, dipeptidyl peptidase IV, and neutral endopeptidase. We suggest that peptidases may modulate cell growth and differentiation by inactivating stimulatory signals (or conversely, by activating inhibitory signals).

Abstract
We report our experience with a one-stage surgery for pediatric cholesteatoma in 216 ears. Our technique is based on three main principles: (1) the surgery is individualized; (2) the goal of surgery is to completely remove cholesteatoma and related disease in one operation; and (3) the reconstruction is performed to provide both good hearing and a dry, trouble-free ear. The incidence of recidivism was 10.2%, and the rate achieved was 13.3% at 5 years and 24% at 10 years. Canal wall down surgery was the predominant procedure used. The incidence of intraoperative neurosensory hearing loss, vertigo, and facial nerve injury was extremely low. The postoperative cavity problems encountered were minimal.

Abstract
The concentration of tris(2-carboxyethyl)phosphine (TCEP) can be conveniently determined by measuring the amount of 2-nitro-5-thiobenzoate (NTB) formed after reaction with 5,5'-dithiobis(2-nitrobenzoic acid) (DTNB). This method utilizes the fact that TCEP reduces DTNB rapidly and stoichiometrically to generate two equivalents of NTB which, in its anionic form, has a molar extinction coefficient of 14,150 M-1 cm-1 at 412 nm. This method is sensitive enough to detect the concentration of TCEP in the micromolar range and has proven useful in monitoring the stability or oxidation of TCEP under various conditions. TCEP is not only very stable in acidic solutions, but unlike dithiothreitol (DTT) which readily oxidizes above pH 7.5, it is also highly stable in basic solutions. The rates of reduction of DTNB by TCEP and DTT are compared in the pH range 6-9. Below pH 8, TCEP is significantly more effective than DTT in reducing this disulfide. The rates of reduction of 2,2'-dithiodipyridine (2,2'-DTDP) by TCEP and DTT are compared in the pH range 1.5-8.5. Unlike DTT which is totally inactive at pH 1.5, TCEP is still capable of reducing 2,2'-DTDP effectively at this pH. Thus, if TCEP and thiols are simultaneously present, the concentration of TCEP can be selectively determined by using 2,2'-DTDP at very low pH.

Abstract
Endoscopic instruments have revolutionized surgical diagnosis and treatment. Recently, a high resolution microfiberoptic endoscope has been developed that has vast potential for otologic use. This microfiberoptic endoscope was used in cadaver and human studies to visualize the middle ear cavity. The technique used involved placing a 1.0-mm or smaller microfiberoptic scope into the middle ear via a tympanic membrane perforation, through a myringotomy tube or up the eustachian tube. Using the scope, the mesotympanum and hypotympanum can be well visualized. Similarly, the round window, oval window, ossicular chain, and related structures can be clearly demonstrated and recorded photographically. This technique has great potential to enhance diagnosis without open surgery.

Abstract
Cholesteatomas are histologically benign, though biologically invasive lesions that arise from the migration of squamous epithelium of the ear. Acquired cholesteatomas usually arise in an antigenically active environment, i.e., a chronically and/or recurrently inflamed middle ear. In contrast, congenital cholesteatomas occur in an uninflamed environment. The potential role of dendritic cells (DCs) in the evolution of this lesion has not been thoroughly studied. By staining for S-100 protein, the authors evaluated the presence and distribution of DCs in cholesteatomas. Sixteen cases of cholesteatomas diagnosed from 1987 to 1989 were selected for this study. The formalin-fixed, paraffin-embedded sections were processed by a standard avidin-biotin peroxidase-antiperoxidase method for S-100 protein and for leukocyte common antigen (LCA). The presence and distribution of S-100 protein-positive DCs was evaluated and compared to canal wall skin. DCs were present in all cases. Nine acquired cholesteatomas had 5 to 16 epithelial DCs per high-power field (HPF). Seven congenital cholesteatomas were examined. Four with isolated congenital pearl-like cholesteatomas had 1 to 3/HPF epithelial DCs. In contrast, the three inflamed congenital cholesteatomas had 6 to 12/HPF DCs. The control uninflamed canal wall skin had only 1 to 3/HPF DCs. All DCs were LCA negative, as expected.

Abstract
Cholesteatomas are invasive, locally destructive skin-like lesions that, after operative removal, have a significant recidivistic rate. These aggressive characteristics suggest a fundamental alteration in the biology of one or more of its constituents (i.e., keratinocytes, fibroblasts, and inflammatory cells). The cholesteatoma matrix was studied by subculturing it into its main cellular components. Short-term cell cultures of fibroblasts from cholesteatoma matrix and controls from ear canal and postauricular skin were established. These cultured fibroblasts were tested for invasiveness using the Boyden Chamber Assay of Albini. The cells were evaluated for their ability to migrate, attach to, and invade a basement membrane. Results of the motility and attachment of fibroblasts cultured from cholesteatoma, canal wall, and postauricular skin did not differ. However, fibroblasts from 12 of 12 cholesteatoma specimens were highly invasive, while those from postauricular and ear canal skin were either weakly invasive or not invasive. This represents the first report of an intrinsic defect in the biology of cholesteatoma. Invasive fibroblasts that demonstrate a loss of growth control, may provide a contact guidance mechanism that aggressively mobilizes the squamous keratinizing epithelium contributing to the invasive, aggressive behavior of cholesteatoma.

Abstract
The intent of this work was to examine the actions of allicin on 1) intraocular pressure (IOP) in normal and unilaterally sympathectomized (SX) rabbits; 2) cAMP accumulation in the rabbit iris-ciliary body (ICB) and cultured nonpigmented epithelial (NPE) ciliary body cells; and 3) 3H-norepinephrine (NE) release by calculating fractional tritium overflow in response to electrical field stimulation (EFS, 5 Hz, 12 V/cm) in isolated, perfused rabbit ICBs. Allicin, one of the active compounds produced by garlic, was evaluated on IOP and it was determined that allicin (1, 2.5, or 10 micrograms), topically, but not the precursor, alliin (10 micrograms), lowered the IOP unilaterally in normal rabbits. Allicin (10 micrograms) reduced the IOP by 6 +/- 1 mmHg (n = 4) in normal rabbits at 2 hrs (maximum response) whereas no change occurred in sympathectomized rabbit eyes. Moreover, allicin (0.01, 0.1, or 1 microM) caused 40, 40, or 52% inhibition, respectively, of 3H-NE overflow in response to EFS. Isoproterenol (ISO, 1 microM) stimulated cAMP accumulation by 3.6 and 9 fold in isolated rabbit ICB and cultured NPE cells, respectively. Allicin (1 microM) had no effect on basal cAMP level while it inhibited ISO-stimulated cAMP accumulation by 40% and 23% in ICB and NPE cells, respectively. This study suggests that allicin lowered IOP, in part, by dual actions at the neuroeffector junction.

Abstract
One hundred twelve patients (116 ears) were treated for recurrent and residual cholesteatoma. A retrospective review revealed that 66% had undergone canal wall down mastoidectomy at the previous surgery. The surgical procedure at revision was selected on the basis of an intraoperative assessment of the extent of disease, and clinical prediction of eustachian tube function. The average period of follow-up was 3.4 years. Revision surgery was successful in providing the patient with a safe, dry ear in 105 (91%) of 116 cases. Surgical principles and hearing results are presented.

Abstract
The surgical management of labyrinthine fistulas caused by cholesteatoma remains controversial. Forty cases (41 ears) of labyrinthine fistulas were reviewed. This represented 10% of our total series of cholesteatomas in adults and children (426 ears). Clinical presentation, extent of disease, results of fistula testing and audiometric studies, and radiographic findings were analyzed. A canal wall-down procedure was performed in all but one patient. Generally an attempt was made to completely remove the cholesteatoma, to graft the fistulous area, and to reconstruct the middle ear mechanism in one stage. The matrix was preserved in patients with large fistulas where the involved ear was the only hearing one, when the matrix was adherent to the underlying optic duct, and in selected elderly persons. Long-term followup did not reveal a significant difference in hearing, degree of vertigo, or incidence of recidivism when those patients in whom the matrix was removed were compared with those in whom the matrix was preserved. The importance of recognizing the presence of a labyrinthine fistula preoperatively is stressed, along with the need to be prepared for an unexpected fistula. Operative management is described.

Abstract
During the past 10 years discrete middle ear congenital cholesteatomas have been detected with greater frequency in young children. The increased recognition of this condition is probably related to the pediatricians' greater awareness of this defect, their improved facility with pneumatic otoscopy, and effective audiometric and tympanometric screening procedures. This early detection while the lesions are small and localized facilitates their surgical removal. Clinically, it would appear that congenital cholesteatomas can be subdivided into two categories according to their anatomic locations. The anterior lesions present as an isolated pearl that arise from an area on the anterior surface of the malleus, are usually associated with normal hearing, and have pneumatized mastoids. The posterior lesions do not seem to originate from a clearly defined anatomic area, have a higher incidence of sclerotic mastoids, and erode the ossicular chain commonly producing a hearing loss. The anterior middle ear cholesteatoma probably arises from a persistent epidermoid formation, a structure that normally is present during fetal development of involutes by the 33rd week of gestation. The origin of cholesteatomas arising in the posterior middle ear space remains more controversial.

Abstract
Spectral analysis along with zero and standard-phase shift digital filtering were performed on evoked potentials recorded from 12 normal hearing subjects. The results indicated a progressive shifting of the mean spectral content of the ABR toward the low frequencies as the stimulus intensity was lowered. Despite this, the effects of zero-phase shift high-pass digital filtering at 100 Hz (36 dB/oct) did not significantly differ between waveforms elicited by a 75 dB nHL, 55 dB nHL, and 35 dB nHL stimulus. The major response frequency of the ABR is related to the distance between the peak (IV/V) and the following major trough (approximates one-half the response period). In waveforms where the major trough occurred before 10 msec, the use of 100 Hz, 36 dB/oct, zero-phase shift high-pass filters produced only a small reduction in response amplitude, even at low stimulus intensity levels. Waveforms which had a major trough (Na1) between 10 to 15 msec were reduced in amplitude by 100 Hz, 36 dB/oct, zero-phase shift high-pass filters (the longer period of the response energy in these waveforms corresponds to a lower energy frequency). However, this trough has a latency that prevents it from being recorded on a 10 msec time base or defined as an ABR. Based on these results, the use of zero-phase shift high-pass filters with a high-pass cutoff frequency that is equal to or less than the resolution of the time base (1/time base) appears to be a desirable method of reducing muscle artifact and other electrical contamination of the ABR.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The active ingredient in du Pont Krenite brush control agent is ammonium ethyl carbamoylphosphonate (fosamine ammonium salt, formerly known as DPX-1108). Residues in channel catfish exposed to 1.1 ppm 14C-carbonyl-labeled fosamine ammonium in water for 4 wk were found to plateau in 2-3 wk with an accumulation factor (ratio of residue in fish to residue in water) of less than 1. In a separate experiment channel catfish were placed for 4 wk in a tank containing [14C]fosamine ammonium-treated soil (15 ppm) that had been aged for 30 d prior to flooding and initiation of fish exposure. The residue levels in this latter group of catfish also plateaued in 2-3 wk with an accumulation factor of less than 1. In both experiments, after the 4-wk exposures, the fish were transferred to fresh water for 2-wk depuration periods, during which residue levels dropped 50--90%. No effects on the fish were observed during these experiments.
