The purpose of this study was to examine the force-time differences between concentric-only half-squats (COHS) performed with ballistic (BAL) or non-ballistic (NBAL) intent across a range of loads. Eighteen resistance-trained men performed either BAL or NBAL COHS at 30%, 50%, 70%, and 90% of their one repetition maximum (1RM) COHS. Relative peak force (PF) and relative impulse from 0⁻50 ms (Imp50), 0⁻90 ms (Imp90), 0⁻200 ms (Imp200), and 0⁻250 ms (Imp250) were compared using a series of 2 × 4 (intent × load) repeated measures ANOVAs with Bonferroni post hoc tests...

BACKGROUND: Pregnancies following assisted reproductive technology (ART) may have elevated potential risk of pregnancy loss (PL) when compared to natural conception. However, rare studies comprehensively analyzed the IVF/ICSI cycle-dependent factors for loss of clinical pregnancy. Therefore, we aimed to determine the ART subgroup-specific risks of PL throughout pregnancy and explore different risk factors for early miscarriage and late miscarriage among pregnancies conceived through ART...

Controlled ovarian hyperstimulation (COH) impairs the synchronized development of endometrium and embryo, resulting in the failure of embryo implantation. Here, we investigated what effects electroacupuncture had on embryo implantation in COH rats. Female rats were randomly assigned to 4 groups: normal (group N), model (group M), electroacupuncture (group EA), and electroacupuncture pretreatment (group PEA). Rats in groups M, EA, PEA were injected with pregnant mare serum gonadotropin and human chorionic gonadotropin to establish the COH model...

Treatment of both [CoCl( tBu PNP)] and [NiCl( tBu PNP)] ( tBu PNP = anion of 2,5-bis((di- tert-butylphosphino)methyl)pyrrole) with one equivalent of benzoquinone affords the corresponding chloride complexes containing a dehydrogenated PNP ligand, tBu dPNP ( tBu dPNP = anion of 2,5-bis((di- tert-butylphosphino)methylene)-2,5-dihydropyrrole). Dehydrogenation of PNP to dPNP results in minimal change to steric profile of the ligand but has important consequences for the resulting redox potentials of the metal complexes, resulting in the ability to isolate both [CoH( tBu dPNP)] and [CoEt( tBu dPNP)], which are more challenging (hydride) or not possible (ethyl) to prepare with the parent PNP ligand...

Cardiovascular disease (CVD) is a leading cause of late morbidity and mortality in hematopoietic cell transplantation (HCT) survivors. HCT-specific CVD risk prediction models are needed to facilitate early screening and prevention. In the current study, patients who underwent HCT at City of Hope (COH) and survived 1-year free of clinically evident CVD (N = 1828) were observed for the development of heart failure (HF) or coronary artery disease (CAD) by 10-years from index date (1 year from HCT). CVD occurred in 135 individuals (92 HF, 43 CAD)...

Embedding methods have shown promising performance in multilabel prediction, as they are able to discover the label dependence. However, most methods ignore the correlations between the input and output, such that their learned embeddings are not well aligned, which leads to degradation in prediction performance. This paper presents a formulation for multilabel learning, from the perspective of cross-view learning, that explores the correlations between the input and the output. The proposed method, called Co-Embedding (CoE), jointly learns a semantic common subspace and view-specific mappings within one framework...

Vertical and adiabatic excitation energies and oscillator strengths for valence and Rydberg states of hydroxycarbene (HCOH) and methylhydroxycarbene (CH3 COH) are reported. The electronic properties were computed with equation-of-motion coupled-cluster methods with single and double substitution methods (EOM-CCSD) and the aug-cc-pVTZ basis set. The states' characters were analyzed by plotting natural transition orbitals (NTOs). The calculations demonstrate that the shape, size, and energy of each Rydberg orbital are affected to varying degrees by their interaction with the ion core...

The aim of the study was to evaluate the effects of early feed exposure (EFE) to different feedstuffs in dairy calves on feed preference once fed a free-choice diet and a total mixed ration later in life. Thirty (30) female Holstein calves were randomly assigned at birth to 1 of 3 EFE treatments-concentrate only (CON), hay only (HO), and concentrate and hay (COH)-from d 2 to 56. After that, all calves were offered both concentrate and hay in different buckets from d 57 to 70 to allow them free choice between the 2 feedstuffs...

Despite the advances in in vitro fertilization (IVF), the implantation success rate for infertile women remains approximately only 15%. In this study, we sought to determine whether implantation failure after repeated IVF treatments is influenced by the presence of common variants in estrogen α, progesterone and follicle stimulating hormone receptor genes. The study population included three groups of women: group 1 were 50 women who had the transfer of ≥3 high-quality embryos during the IVF procedure without ever having had a clinical pregnancy; group 2 were 50 women who achieved a clinical pregnancy after ≤3 high-quality embryos transfers and group 3 were 50 control subjects who achieved a clinical pregnancy without any fertility therapy that resulted in a one live-born infant...

The syntheses of [OC(COX)3][MF6] and [(COX)4][MF6]2∙2HF were carried out in superacidic media XF/MF5 (M = As, Sb; X = H, D). The degree of protonation is highly dependent on the stoichiometric ratio of the Lewis acid with regard to squaric acid. The salts of diprotonated squaric acid were characterized by Raman spectroscopy and in the case of [(COH)4][MF6]2∙2HF (M = As, Sb) by single crystal X-ray structure analyses. [(COH)4][AsF6] crystallizes in the monoclinic space group P21/n with two formula units per unit cell...

CoFe Prussian blue analogues (PBAs) are well-known for their magnetic bistability tuned by external stimuli. The photoswitching properties are due to the electron transfer from CoLS III -NC-FeLS II to CoHS II -NC-FeLS III linkage, accompanied by the spin change of the Co ions (HS stands for high spin and LS for low spin). In this work, we investigated 100 nm particles of the Rb2 Co4 [Fe(CN)6 ]3.3 ·11H2 O PBA (named RbCoFe). The photoexcited state of the PBA was reached by red laser excitation (λ = 635 nm) and observed by X-ray absorption spectroscopy and X-ray magnetic circular dichroism (XMCD) that are element-specific probes...

Sodium carbonate-soluble pectin fraction forms a self-organized network on mica and may have the potential ability to bind zinc ions. The aim of this research was to characterize the interaction of zinc ions with this fraction extracted from apples using rheological measurements and FT-IR study. The addition of zinc ions (10 and 20 mM of ZnSO4 ·7H2 O) to 5% pectin water solution caused a significant increase in viscosity, which may be connected with the formation of a pectin network. Moreover, the addition of zinc ions resulted in an almost 1...

PURPOSE OF REVIEW: Surgery has traditionally been the primary treatment option for endometriosis-related infertility of any phenotype. However, advances and refinements of assisted reproductive technologies (ART) permit a more conservative approach in many scenarios. This review summarizes the latest findings in the field of reproductive medicine, which have supported a paradigm shift towards more conservative management of ovarian endometrioma. RECENT FINDINGS: The presence of ovarian endometrioma per se is likely to impair ovarian reserve and alter ovarian functional anatomy...

The recorded phonocardiogram (PCG) signal is often contaminated by different types of noises that can be seen in the frequency band of the PCG signal, which may change the characteristics of this signal. Discrete wavelet transform (DWT) has become one of the most important and powerful tools of signal representation, but its effectiveness is influenced by the issue of the selected mother wavelet and decomposition level (DL). The selection of the DL and the mother wavelet are the main challenges. This work proposes a new approach for finding an optimal DL and optimal mother wavelet for PCG signal denoising...
