Comprehensive Assessment of Serum Estradiol Impact on Selected Physiologic Markers Observed During in-Vitro Fertilization and Embryo Transfer Cycles

Objective: This investigation assessed the effect of serum estradiol levels on outcomes of in-vitro fertilization and embryo transfer (IVF) cycles. Materials and Method: This was a retrospective cohort study of 1123 IVF cycles comparing impact of estradiol (E 2) levels on follicular development, fertilization, embryo quality, implantation, pregnancy rate, miscarriage rate, and selected obstetric complications. Results: We found high serum E 2 levels to be significantly associated with increased number of mature follicles and mature oocytes retrieved (p&amp;lt;0.01, for both). E 2 levels were also associated with more viable and good-quality embryos (p&amp;lt;0.01). There was no significant impact of E 2 on oocyte maturation, fertilization rate, embryo quality, or overall pregnancy rates. Moreover, high E 2 levels were significantly associated with higher implantation rates and reduced incidence of miscarriage (p&amp;lt;0.05, for both). Conclusion: Within the safety range in clinical practice, our data demonstrate a generally positive effect of high serum E 2 on selected IVF parameters.

Union and tangle

Shibuya proved that any union of two nontrivial knots without local knots is a prime knot. In this note, we prove it in a general setting. As an application, for any nontrivial knot, we give a knot diagram such that a single unknotting operation on the diagram cannot yield a diagram of a trivial knot.

Spatio-temporal Receptivity of Boundary-Layers by Bromwich Contour Integral Method

Transition from laminar to turbulent flow occurs via inherent instability of the former caused by the omnipresent background disturbances. While the motivation behind the famous experiments of [5] was to relate the instability with the disturbance level, most theoretical analyses, studies transition as an eigenvalue problem- in either temporal or spatial framework. Significant progress made by this approach is recorded in [2], while many issues still remain unresolved. For example, plane Couette and Poisseuille flow are found stable by eigenvalue analysis for certain parameter combinations, while lab experiments reveal them to be unstable. Classical approaches in this field, involve identifying equilibrium states whose stability is studied by eigenvalue analysis, by linearizing the governing mass and momentum conservation equation and then expressing it in the spectral plane after making the parallel flow assumption, leading to the well-known Orr-Sommerfeld equation. The least stable mode, often display wave-like nature and is said to produce the Tollmien-Schlichting (TS) waves. In general fluid dynamic systems, it is not known a priori whether distrubances grow in space or in time or as spatio-temporal structures and this issue has not been resolved by instability studies. The alternative is to use receptivity studies where the response of the system is obtained with respect to impressed disturbances. For localized harmonic excitation, in [3] and [6] the assumption, that the response is at the frequency of the imposed excitation was made for the ease of the receptivity calculation and this is known as the signal problem. In [7] this assumption was removed and the complete spatio-temporal analysis was made using Bromwich contour integral method. For a zero pressure gradient boundary-layer, it was shown that this and the signal problem produces identical response field, for those cases where the system is spatially unstable. In a recent study [8], it has been shown that these two approaches do not produce identical results for spatially stable systems and indicates the necessity of performing spatio-temporal receptivity studies by the Bromwich control integral method. In the present study, we show the composite nature of the response field obtained by the Bromwich contour integral method. We identify the near- and far-field response of a stable system for the zero pressure gradient boundary layer, and finally explain the structure of the near-field analytically.

A history of the Asian monsoon and its interactions with solid Earth tectonics in Cenozoic South Asia

Abstract Although there is some evidence for an Eocene monsoon, the most important intensification of rainfall appears to start at c. 24 Ma in the Early Miocene. Many palaeoceanographical proxies for monsoon intensity are linked to wind and do not correlate well with humidity of the continental climate over tectonic timescales. Rainfall peaked in the middle Miocene ( c. 15 Ma) with strong drying after 8 Ma. This timing does not correlate well with either initial uplift of the Tibetan Plateau or with the retreat of shallow seas from central Asia. The c. 24 Ma onset of strengthening rainfall is associated with the initiation of rapid erosion and cooling of Himalayan metamorphic rocks. The progressive detachment of the subducting Indian lithosphere from the eastern and western syntaxes at c. 25 Ma to the east-central Himalaya at c. 13–11 Ma would have produced corresponding propagation of rising Himalayan topography following release of the weight of the detached slab. Rapid uplift of the Himalayan barrier, blocking moisture-laden winds, is considered the most likely trigger for a stronger summer monsoon in South Asia, which in turn allowed faster erosion and exhumation of the Greater Himalaya after 24 Ma.

Looted Archaeological Sites: Are They Worthy of Scientific Investigation?

Since the late 1800s, looting of prehistoric and historic Bles has been recognized as a serious threat to archaeological resources throughout the world (Knoll 1991}. Looting destroys both recorded and unrecorded sites in the United states (Ahlstrom 1992, Honeycutt et al. 1985, stuart 1989). With such a great amount of looting taking place, this research paper asks a basic question: Why do archaeologists not investigate looted archaeological sites as they do nonlooted sites and features? This question will be answered by reviewing the literature about looting including the archaeological reaction to looting. Two looted features, potted privies, will be discussed to test the potential of looted sles. The results of this paper will imply the necessity and importance for archaeologists to study looted features.

Increased strengthening of austenitic alloys through dual aging

A study of the effect of solution treatment, single and duplex isothermal aging heat treatments on an Fe-Ni-Ti-Al austenitic alloy hardened by ..gamma..' precipitation is reported. Sequential heat treatments were performed and studied in order to develop a systematic process for achieving very high strength austenite through thermal processing alone. Room temperature tensile tests were carried out. Alloys receiving double aging treatments were found to achieve mechanical properties superior to those aged at a given temperature. An optimum level of yield strength (172 Ksi) along with good elongation (20%) was obtained from a two-step aging process. Structural examination indicated that overaging was retarded by secondary aging. The formation and growth of cellular precipitates were suppressed. Resistivity changes were measured on wire specimens to study the early stages of precipitation. Resistivity peaks were observed during secondary aging indicating evidence of secondary precipitation.

The Repercussions of COVID-19 Pandemic, its Socio-economic Changes, in the Jordanian Family and Ways to Prevent them (A Sociological Study)

The repercussions of COVID-19 pandemic, its Socio-economic changes, in the Jordanian family and ways to prevent them A sociological study Abstract The current study aimed to identify the Socio-economic changes caused by the COVID-19 pandemic in the Jordanian family from the point of view of university students and the role of the Jordanian family in preventing it. Social sample surveying approach and stratified random sampling were applied. The sample consisted of (215) male and female students. Descriptive approach (percentages, advanced statistical methods were used. The results revealed that there were significant changes caused by COVID-19 on Jordanian family, including social changes represented by lack of participation in social events motivated by mitigating the negative aspects of COVID-19 and the rise in social responsibility. The results showed a change in the rituals of mourning and marriage customs; also, an increase in media follow-up by family members. The results revealed educational burden on family regarding e-learning, and indicated that the COVID-19 affected, to a moderate degree, families in terms of social stigmatization. Regarding the economic changes, there were high level economic changes affecting the Jordanian family, such as the emergence of woman’s role in the family due to her increased production responsibilities, and new productive roles like producing bread and household products to reduce family members’ leaving house to preserve their health and reduce expenses. There were additional financial burdens shouldered by family which was satisfied with providing basic materials only.

Mild cognitive impairment and mood: a systematic review

Summary This systematic review, with meta-analyses conducted where data were available, aimed to investigate the prevalence of symptoms of depression and anxiety in mild cognitive impairment (MCI), and to establish how symptoms of depression and anxiety relate to the progression from no cognitive impairment to MCI, and from MCI to dementia. Sixty studies were included in the review. Meta-analyses indicated that symptoms of depression and anxiety were more prevalent in people with MCI than in people with normal cognitive function, and increased the risk of progression from no cognitive impairment to MCI. There were mixed results regarding the effect of such symptoms on progression from MCI to dementia. The findings highlight the need for more research in this area, which can inform attempts to slow or halt the progression of cognitive impairment in later life, with resulting benefits for quality of life.

New Insights Into the Mechanism of Action of Endothelin-1 on Cerebral Microcirculation

EVALUATION OF: Faraco G, Moraga A, Moore J, Anrather J, Pickel VM, Iadecola C. Circulating endothelin-1 alters critical mechanisms regulating cerebral microcirculation. Hypertension 62(4), 759–766 (2013). This article reviews a study by Faraco and colleagues that attempts to elucidate the mechanism of modulation of the cerebral blood flow by endothelin (ET) 1. ET1 is one of the most powerful vasoconstrictors and plays an important role in cerebrovascular disease and traumatic brain injury. However, the details of the mechanism of action of ET1 are still unknown. The study used a mouse model with a skull window through which the cortical cerebral blood flow was measured with a laser Doppler probe while various agents were applied. The role of reactive oxygen species and integrity of the blood–brain barrier were also assessed. In addition, the location of the ET receptor was determined by incubation of cortex samples with specific antibodies. ET1 increased mean arterial pressure and attenuated the cerebral blood flow increase stimulated by neuronal activity or the endothelium-dependent acethylcholine but not by A23187. ET1 suppresses the endothelial production of nitric oxide by modulating the endothelial nitric oxide synthase phosphorylation through Rho-associated protein kinase. This effect was mediated by an ETA receptor coupled to phospholipase C via GTP-binding protein and was not related to oxidative stress. The ETA receptor was found in the smooth muscle cells of the pial arterioles and cerebral endothelial cells. The resultant vascular dysfunction may increase the risk of brain ischemia by attenuating the cerebrovascular reserve. Improved understanding of the mechanism of action of ET1 on cerebral microcirculation is likely to stimulate the development of new and promising pharmacological targets.

Effects of task complexity and English proficiency on EFL learners’ task production in SCMC (Synchronous Computer-Mediated Communication).

This study investigates the effects of the cognitive complexity of tasks and pair proficiency on task production in Synchronous Computer Mediated Communication. In particular, this study explores whether task complexity and EFL learners’ proficiency have an effect on the accuracy, the fluency, and the use of strategy of task production in SCMC. 90 Korean high school EFL learners collaboratively completed the cognitively simple and complex tasks, using a browser-based chat program. Based on learners’ English proficiency, each dyad was composed of three different sets: High-High pair, High-Low pair, and Low-Low pair. The data were analyzed by a 2 X 4 analysis of variance (ANOVA). Error-free C-units, words per C-unit were served as dependent variables. Results show that the cognitive complexity of a direction-giving map task significantly affects task production. Pair composition also significantly affects the number of error-free C-units, words per C-unit and the use of strategy. This study confirms a previously reported increase in quantity of strategy used by students of the pairs with different English proficiency levels, compared to other pairs with similar English proficiency levels. The findings offer pedagogical implications for designing task-based synchronous interaction to facilitate Korean EFL learners’ accuracy, fluency and the use of strategy.

Evaluation of the effect of SmearOFF on Smear Layer Removal and Erosion of Root Canal Dentin An in Vitro Study

Background and Objectives: Root canal instrumentation produces a smear layer that covers the root canal walls and may have adverse effects on endodontic treatment. SmearOFF is a new endodontic irrigant, which proposes smear layer removal and microbial elimination in one step. The aim of the present study was to evaluate and compare the effect of SmearOFF with other final irrigants regarding smear layer removal and degree of erosion from the apical third of root canals. Methods: Forty mandibular premolar roots with single canals were selected. The teeth were randomly divided into 4 groups of 10 teeth each according to the type of final irrigants used during and after instrumentation: G1 6% NaOCl/ distilled water (control), G2 6% NaOCl/Qmix, G3 6% NaOCL/SmearOFF, G4 6% NaOCL/ 17% EDTA. All teeth were shaped by using ProTaper NEXT rotary system till X2. 6% NaOCl was applied with a 27-G side-vented syringe needle as an initial irrigant followed by the final irrigants. Endoultra ultrasonic device was used for irrigation activation. The samples were then submitted to scanning electron microscopy to evaluate the effectiveness of proposed treatments. Results: In smear layer variables score 2 was the most occurred value for G2 (QMIX) and G3 (SmearOFF), whereas in G1 (Distilled water) and G4 (17% EDTA) are 3 and 1 respectively. For erosion variable, erosion was most evident in G4 (6% NaOCL/ 17% EDTA). There were no significant differences between G2 and G3 and also between G3 and G4 in both smear layers and erosion. Conclusion: 17% EDTA, SmearOFF, and QMix using PUI can remove smear layer effectively from the apical third. In the future, SmearOFF may act as a promising chelating agent as well as an antimicrobial irrigant.

A novel semi-supervised feature extraction algorithm

Supervised feature extraction algorithms usually require lots of labeled samples to achieve good performance. However, labeling the samples is often time-consuming and even impractical. Therefore, in this paper, a semi-supervised manifold local Fisher discriminant analysis (SMLFDA) is proposed to take advantage of unlabeled samples as well as labeled samples. The proposed algorithm utilizes local scatter matrix and manifold structure to extract the information from labeled and unlabeled samples, respectively, which significantly improves the accuracy of successive classification application when labeled samples are insufficient. In addition, an exponential form weighting coefficient is proposed to further improve the classification performance. Experiments of hyperspectral classification demonstrate the effectiveness of the proposed semi-supervised feature extraction algorithm.

Numerical simulation of damage characteristics of jointed rock under blasting load

In nature, rock masses are often accompanied by joints and weak interlayers. Due to the existence of joints, rock masses are characterized by anisotropy. When the rock mass is excavated by the blasting method, the joints and situ stresses have a great influence on the propagation of the explosion stress wave and the propagation of cracks. In this paper, a two-dimensional finite element model is used to calculate the damage and cracking of jointed rocks under blasting load. Results have shown that the angle between borehole and joint can affect the development of rock crack, and the propagation of stress wave can be suppressed. In addition, it has been verified that initial stress field and its magnitudes of major principal stresses affect the development of the crack zone around the borehole.
