Study of Placental Insufficiencies in IUGR Babies in Term Pregnancies

In intrauterine growth restricted babies, at term, the placenta might hold the key to the etiology. This present study is aimed at comparison of data of gross and pathological study of placentae from normal weight (control) and IUGR groups and attempted to establish a relationship between placenta pathology and intrauterine growth retardation in term pregnancy.  1. To study placental factors associated with IUGR. 2. To study prevalence of placental factors in details.  A study of 100 patients, with more 37 and less 42 weeks of gestation wasconducted for 2yrs in a tertiary care hospital. A thorough general examinationaSystemic examination which included per abdominal examination including uterine height, abdominal girth, symphysio fundal height, estimated fetal weight, abdominal grips, fetal heart auscultation, and per vaginal examination. Routine and specific investigations will be sent for clinical correlation. Placenta obtained after delivery was send for macroscopic and microscopic examination to pathologist. The reports obtained will be used to study placental causes in IUGR and placenta in detail.  Average placental weight of term pregnancy is 400 gms and placental coefficient is 0.18. decidual surface area is 254 cm2 and its thickness is 2.72cm. Retroplacental haemorrhage is closely associated with PIH. Microscopic infarction is found with high frequency (p<0.005). Placenta of IUGR fetus, gross pathological changes like severe infarction with or without retroplacental haematoma can obviously be noted but they are not found to be statistically significant. Placental coefficient is increased in cases of anemia. Syncytial knot formation in excess and thickening of basement membrane is well correlated.

Leptogenesis via collisions: leaking lepton number to the hidden sector.

We propose a leptobaryogenesis mechanism in which the nonzero B-L of the Universe is produced in out-of-equilibrium, lepton number and CP-violating scattering processes that convert ordinary particles into particles of some hidden sector. In particular, we consider the processes l phi-->l(')phi('),l macro(')phi(') mediated by the heavy Majorana neutrinos N of the seesaw mechanism, where l and phi are ordinary lepton and Higgs doublets and l('), phi(') are their hidden counterparts. Such a leptogenesis mechanism is effective even if the reheat temperature is much smaller than the heavy neutrino masses. In particular, it can be as low as 10(9) GeV.

Practical Frameworks For h-Out-Of-n Oblivious Transfer With Security Against Covert and Malicious Adversaries

We present two practical frameworks for h-out-of-n oblivious transfer (OTn h ). The first one is secure against covert adversaries who are not always willing to cheat at any price. The security is proven under the ideal/real simulation paradigm (call such security fully simulatable security). The second one is secure against malicious adversaries who are always willing to cheat. It provides fully simulatable security and privacy respectively for the sender and the receiver (call such security one-sided simulatable security). The two frameworks can be implemented from the decisional Diffie-Hellman (DDH) assumption, the decisional N -th residuosity assumption, the decisional quadratic residuosity assumption and so on. The DDH-based instantiation of our first framework costs the minimum communication rounds and the minimum computational overhead, compared with existing practical protocols for oblivious transfer with fully simulatable security against covert adversaries or malicious adver-

On deoxidization theory in modern education and its criticism——Also on order law in modern education

Deoxidization theory is a kind of modern philosophy. It presumes that every thing is an aggregation or combination composed with some more simply or more radical thing. The whole movement of the world or the system is the summation which is composed with every part or element. Deoxidize theory is important methodology in modern education. All complicated education phenomena and activity are deoxidized as some simply matter facts. Human being is deoxidized as a set of society law. When modern education emphasizes to follow society law, it gives up to follow the intrinsic law of human, so that education loses its inherent obligation to cultivate good man and induct people to have a good life.

Cuba and the Missile Crisis

On 16 October 1962, President John F. Kennedy learned that the Soviet Union was building bases in Cuba for ballistic missiles that could destroy major US cities. In the days that followed, US officials focused nearly all their attention on strategies for removing the Soviet missiles, on Soviet motives, and on the Soviet Union's reaction to the naval quarantine. Cuba was the locus of this most dramatic superpower confrontation, but Cuban perceptions, motives, and reactions were largely ignored.

Formation and Decay of Chiral Condensates in Relativistic Heavy Ion Collisions

We discuss the various physics aspects of hypothetical, coherent excitations of the pion field caused by spontaneously generated local distortions of the chiral order parameter. Such distortions, which may occur in the expansion of a hot fireball created in relativistic nuclear collisions, may be influenced or even triggered by the interaction with strong electromagnetic fields through the axial anomaly. We suggest that semiperipheral collisions may provide the best environment for the formation of these disoriented chiral condensates.

Isotopic studies of the late Archean plutonic rocks of the Wind River Range, Wyoming

Isotopic studies of the Rb-Sr and U-Th-Pb systems in whole-rock samples and the U-Pb systematics for zircons document the existence of two late Arehean intrusive events in the Wind River Range. All of the systems examined indicate an age of ∼2,630 ± 20 m.y. for the Louis Lake batholith. Apparent ages for the Bears Ears pluton range from 2,504 ± 40 m.y. to 2,575 ± 50 m.y. The scatter in apparent ages for the Bears Ears pluton does not appear to be primarily the result of disturbance by postintrusive events, but it may be explained by an isotopically inhomogenous magma at the time of intrusion. Data for a few samples indicate that the Wind River Range was affected locally by a postmagmatic hydrothermal event that was approximately Tertiary in age. This event lowered δ 18 O values and disturbed parent-daughter relationships in most of the isotopic systems investigated, but it was recent enough that there is no demonstrable effect in the Pb-Pb system. The Bears Ears pluton has some chemical and petrologic features that are similar to those reported for the granites in the Granite Mountains to the east. These granites are spatially associated with low-temperature uranium deposits of Tertiary age and have been shown to have lost large amounts of uranium during the early to middle Tertiary. U-Pb systematics indicate, however, that the low to moderate uranium contents and highly variable Th/U values noted for the Bears Ears pluton are best interpreted as being primary features. If uranium was lost after magma generation, the loss most likely occurred at the time of intrusion. Such a loss could account for uraniferous Precambrian pegmatites southwest of the main part of the Range. The two intrusive units apparently were derived from different protoliths that were formed during early to middle Archean. Initial isotopic ratios and petrochemistry for the Louis Lake batholith are consistent with an early Archean trondhjemitic to tonalitic source. The protolith for the Bears Ears pluton must have been more evolved and somewhat younger. Inconsistencies as to the degree of evolution of this protolith, as inferred from isotopic and trace-element data, suggest that the protolith may have been subjected to high-grade meta-morphism that caused loss of Rb and U prior to generation of the magma.

Characterization of growing bacterial populations in McMurdo Dry Valley soils through stable isotope probing with (18) O-water.

Soil microbial communities of the McMurdo Dry Valleys, Antarctica (MDV) contain representatives from at least fourteen bacterial phyla. However, given low rates of microbial activity, it is unclear whether this richness represents functioning rather than dormant members of the community. We used stable isotope probing (SIP) with (18) O-water to determine if microbial populations grow in MDV soils. Changes in the microbial community were characterized in soils amended with H2 (18) O and H2 (18) O-organic matter. Sequencing the 16S rRNA genes of the heavy and light fractions of the bacterial community DNA shows that DNA of microbial populations was labeled with (18) O-water, indicating these micro-organisms grew in the MDV soils. Significant differences existed in the community composition of the heavy and light fractions of the H2 (18) O and H2 (18) O-organic matter amended samples (Anosim P < 0.05 of weighted Unifrac distance). Control samples and the light DNA fraction of the H2 (18) O amended samples were dominated by representatives of the phyla Deinococcus-Thermus, Proteobacteria, Planctomyces, Gemmatimonadetes, Actinobacteria and Acidobacteria, whereas Proteobacteria were more prevalent in the heavy DNA fractions from the H2 (18) O-water and the H2 (18) O-water-organic matter treatments. Our results indicate that SIP with H2 (18) O can be used to distinguish active bacterial populations even in this low organic matter environment.

Racism's effect on depressive symptoms: Examining perseverative cognition and Black Lives Matter activism as moderators.

Additional research is needed on the link between racial discrimination and depressive symptoms over time as well as the risk and resilience moderators that influence this link. One understudied factor that may exacerbate this link is perseverative cognition-chronic activation of stress-related cognitive representations. However, race-specific activism, like Black Lives Matter (BLM) activism, may attenuate this association. Given this, the current study investigated autoregressive and cross-lagged associations between racial discrimination and depressive symptoms across two time points over 6 months. We also tested if perseverative cognition and two domains of Black Lives Matter activism-support and behavior-moderated the cross-lagged associations between racial discrimination and depressive symptoms. Using data from 232 African Americans, findings revealed a significant cross-lagged effect of Time 1 racial discrimination on Time 2 depressive symptoms (but no cross-lagged effect of T1 depressive symptoms on T2 racial discrimination). This cross-lagged effect was moderated by both perseverative cognition and support for BLM activism such that the association between Time 1 racial discrimination was only associated with Time 2 depressive symptoms at lower levels of perseverative cognition and lower levels of BLM support.

Selective Memory and the Persistence of Paradoxical Self-Esteem

Previous research suggests that paradoxical self-esteem (contrasting levels of self-liking and self-competence) is associated with selective memory for self-relevant information. The form and function of this bias was examined here. College students classified as paradoxical or nonparadoxical viewed a series of trait adjectives. Recognition memory for the words was later tested. Results revealed that heightened selectivity in paradoxicals was limited to words conveying low social worth. Those paradoxically low in self-liking showed distinctively good memory and those paradoxically high in self-liking showed distinctively bad memory for these words. The claim that memory bias contributes to the persistence of paradoxical self-esteem also was tested. As expected, the self-liking of paradoxicals with the strongest memory bias showed the least shift toward self-competence 4 months later.

Risk factors for renal function impairment in a series of 502 patients born with spinal dysraphisms.

To evaluate the risk of renal damage in a large series of patients affected by spinal dysraphism.



Renal function was studied in 502 spinal dysraphisms treated over the last 25 years in a single center: 283 meningomyelocele (MMC), 90 caudal regression syndrome (CRS) and 129 spinal lipoma (SL) cases. In patients with normal and impaired renal function, we compared congenital renal anomalies, vesicoureteric reflux, bladder voiding pattern and upper tract dilatation, analyzing the results with the Fisher test.



Neuropathic bladder was observed in 97% of MMC, 60% of CRS, and 39% of SL cases. There was some degree of renal function impairment in 19 MMC (6.7%), 11 CRS (12%, increased to 20% if considering only neuropathic bladder patients), and two SL (1.5%) cases. Renal agenesis was more frequent in CRS (13%), but was not associated with decreased renal function. Overall, vesicoureteric reflux and upper tract dilatation were more frequent in patients with renal damage. Insufficient bladder voiding was statistically associated with renal damage only in the CRS population. Intermittent catheterization did not represent a protective factor against renal damage in patients able to void without significant residual urine.



This study has increased our understanding of the prognostic risk factors for renal deterioration. More prospective studies are necessary to confirm these results and correlate treatment with renal outcome.

Recent Progress in Electrochemical HbA1c Sensors: A Review

This article reviews recent progress made in the development of electrochemical glycated hemoglobin (HbA1c) sensors for the diagnosis and management of diabetes mellitus. Electrochemical HbA1c sensors are divided into two categories based on the detection protocol of the sensors. The first type of sensor directly detects HbA1c by binding HbA1c on the surface of an electrode through bio-affinity of antibody and boronic acids, followed by an appropriate mode of signal transduction. In the second type of sensor, HbA1c is indirectly determined by detecting a digestion product of HbA1c, fructosyl valine (FV). Thus, the former sensors rely on the selective binding of HbA1c to the surface of the electrodes followed by electrochemical signaling in amperometric, voltammetric, impedometric, or potentiometric mode. Redox active markers, such as ferrocene derivatives and ferricyanide/ferrocyanide ions, are often used for electrochemical signaling. For the latter sensors, HbA1c must be digested in advance by proteolytic enzymes to produce the FV fragment. FV is electrochemically detected through catalytic oxidation by fructosyl amine oxidase or by selective binding to imprinted polymers. The performance characteristics of HbA1c sensors are discussed in relation to their use in the diagnosis and control of diabetic mellitus.

Predicting grain size in gravel-bedded rivers using digital elevation models: Application to three Maine watersheds

Riverbed grain size controls suitability of spawning habitat for threatened fish species. Motivated by this relationship, we developed a model that uses digital elevation models (DEMs) to predict bed grain size. We tested the accuracy of our model and two existing models with channel measurements from high-resolution airborne light detection and ranging (LiDAR) DEMs. All three models assume that bed grain size is a function of reach-average high-flow channel hydraulics (measured by shear stress or stream power). Our test data are field measurements of median grain size ( D 50 ) at 276 stations along four rivers in Maine. Pleistocene continental glaciation strongly influences the longitudinal profiles, which have alternating steep and gradual segments. We exploit the resulting variations in sediment supply to understand the controls on model success or failure in predicting bed grain size. Results show that all three models have ∼70% success in predicting D 50 within a factor of two overall, and better where the rivers are coarse gravel bedded (∼80% success where D 50 ≥ 16 mm). This similarity is unsurprising given that the models primarily rely on channel gradient (S) and drainage area as inputs. Measurements of S from LiDAR DEMs yield only a modest improvement in model success over those from topographic maps. We find that our model works best in sediment-starved steep reaches. Model failures fall into two broad categories: (1) relatively fine-grained ( D 50 D 50 . We argue that models based on airborne infrared LiDAR DEMs may reach a maximum around 80%–85% accuracy due to these sub-reach-scale factors, which cannot be easily measured from DEMs. The overall success of the models in predicting grain size indicates that the morphology of these channels has adjusted to the imposed S and sediment load during the ∼15 k.y. since deglaciation and through the period of anthropogenic channel change over the past three centuries.

[Effects of scoparone on hemodynamics in anesthetized rabbits].

The effects of scoparone (Sco), tetramethylpyrazine (TMP), and papaverine (Pap) on hemodynamics were compared in anesthetized rabbits. Three dosage levels (1.25, 2.5, 5 mg.kg-1, iv) were used for each agent. Sco lowered the blood pressure (BP), increased the cerebral blood flow (CBF) dose-dependently, but did not show significant influence on the femoral artery blood flow (FBF), the maximal decrease of BP, and the maximal increases of CBF being 15% and 20% of the control, respectively. In contrast, TMP raised the BP as well as increased the CBF and FBF simultaneously. Pap, however, lowered the BP, slightly increased the CBF and decreased the FBF only at large doses. The results suggested that Sco may cause a selective dilatation of cerebral blood vessels.

Can governments push providers to collaborate? A comparison of hospital network reforms in France and the United States.

France recently implemented a program to encourage greater collaboration among public hospitals, which represent about 65 percent of total capacity, by placing them into regional groupings known as Groupements Hospitalier Territoire (GHTs) and mandating that facilities within them share several core functions. The strategy echoes that of Accountable Care Organizations (ACOs) in the United States, which offer financial incentives to providers to form networks that foster collaboration. While the programs share an underlying strategy for improving care and reducing costs, the difference in approaches, mandatory versus voluntary, could significantly affect outcomes. We analyzed aspects of the programs that could lead to differences in their results. ACOs appear to have several advantages, as financial inducements have proven effective in shaping provider behavior in other contexts. GHTs may benefit from a more direct approach, but mandatory participation risks pushback. Regardless of whether the programs succeed in fostering effective care integration, they may accelerate provider consolidation, which could impair access in already underserved areas by concentrating resources in larger facilities and promoting the closure of smaller ones.

Vector-valued Hardy inequalities andB-convexity

AbstractInequalities of the form
$$\sum\nolimits_{k = 0}^\infty  {|\hat f(m_k )|/(k + 1) \leqslant C||f||_1 } $$
 for allf∈H1, where {mk} are special subsequences of natural numbers, are investigated in the vector-valued setting. It is proved that Hardy's inequality and the generalized Hardy inequality are equivalent for vector valued Hardy spaces defined in terms ff atoms and that they actually characterizeB-convexity. It is also shown that for 1<q<∞ and 0<α<∞ the spaceX=H(1,q,γa) consisting of analytic functions on the unit disc such that
$$\int_0^1 {(1 - r)^{q\alpha  - 1} M_1^q (f,r) dr<  \infty } $$

The membrane bioreactor with coenzyme recycling system.

Much attention has been paid to membrane bioreactors, especially to the newly developed charged membrane bioreactor (CMBR) for recycling the native form of the coenzyme NAD(P)H. Charged membranes with anionic groups effectively retained the free nicotinamide coenzyme due to the electrostatic repulsion between membrane and coenzyme. The capability of the CMBR was demonstrated by the continuous production of sorbitol using a multi-enzyme system of NADPH-dependent aldose reductase and glucose dehydrogenase. Several important features of the CMBR were elucidated by a theoretical model of coenzyme turnover.

IFN-γ and CIITA modulate IL-6 expression in skeletal muscle

Interleukin 6 (IL-6) is a secreted cytokine that is an important mediator of the immune response in numerous tissues, including skeletal muscle. IL-6 is considered a myokine as it can be secreted by muscle. IL-6 is secreted following exercise, where it exerts both pro-myogenic effects as well as anti-myogenic effects such as promoting atrophy and muscle wasting. The regulation of IL-6 in skeletal muscle is not well understood. The purpose of this study was to determine if IFN-γ and TNF-ɑ stimulate IL-6 in skeletal muscle. We found that both IFN-γ and TNF-α stimulate IL-6 in skeletal muscle, but the stimulation is not cooperative as seen in monocytes. We have previously shown that the IFN-γ stimulated class II major histocompatibility complex transactivator (CIITA) mediates many of the effects of IFN-γ in skeletal muscle and we show here that CIITA directly stimulates IL-6. The regulation of IL-6 by CIITA is clearly complex, as we found that CIITA both stimulates and restrains IL-6 expression. To show that these effects could be observed in a physiological setting, mice were treated with IFN-γ and we found that both CIITA and IL-6 were upregulated in skeletal muscle.
