Abstract

Two new single-nucleotide polymorphisms (SNPs) (C1166T and G1190A) were discovered in the follicle-stimulating hormone receptor (FSHR) gene and two (G261A and T302C) in the zona pellucida glycoprotein (ZP3) gene. These SNPs were genotyped in three Chinese domestic purebred sow lines (42 Small Meishan, 46 Qingping and 41 Jinhua sows) and three European purebred sow lines (225 Duroc, 195 Large White and 65 Landrace sows) by using SNP chips. Phenotypic data including the functional teat number (i.e. milk-producing teats, TN) and number of piglets born alive per litter (NBA). These traits were tested for association with the genotypes of four SNPs. The association analysis revealed genotype of G261A in the ZP3 gene was significantly (P < 0.01) associated with overall NBA and NBA at later parities (NBA2+) but not with NBA at first parity (NBA1). There was a significant (P < 0.05) difference between sows with genotype GG (14.83 ± 0.18) and AA (14.26 ± 0.09) in TN at position 261 in the ZP3 gene. No significant associations were observed for the SNPs in the FSHR gene with NBA or TN in our populations. The results showed that the new SNPs in the ZP3 gene may be an effective potential marker to be used in conjunction with traditional selection methods.

Abstract

A massless particle beyond the Standard Model is searched for in the two-body decay Σ+→p+invisible using (1.0087±0.0044)×1010 J/ψ events collected at a center-of-mass energy of s=3.097GeV with the BESIII detector at the BEPCII collider. No significant signal is observed, and the upper limit on the branching fraction B(Σ+→p+invisible) is determined to be 3.2×10−5 at the 90% confidence level. This is the first search for a flavor-changing neutral current process with missing energy in hyperon decays which plays an important role in constraining new physics models.

Abstract

The spin and parity of the charmed mesons Ds⁎+, D⁎0 and D⁎+ are determined for the first time to be JP=1− with significances greater than 10σ over other hypotheses of 2+ and 3−, using an e+e− collision data sample with an integrated luminosity of 3.19 fb−1 collected by the BESIII detector at a center-of-mass energy of 4.178 GeV. Different spin-parity hypotheses are tested via a helicity amplitude analysis of the processes e+e−→Ds⁎+Ds−, D⁎0D0 and D⁎+D−, with Ds⁎+→Ds+γ, D⁎0→D0π0, and D⁎+→D+π0. The results confirm the quark model predictions.

Abstract

We search for the semi-leptonic decays Λc+→Λπ+π−e+νe and Λc+→pKS0π−e+νe in a sample of 4.5fb−1 of e+e− annihilation data collected in the center-of-mass energy region between 4.600GeV and 4.699GeV by the BESIII detector at the BEPCII. No significant signals are observed, and the upper limits on the decay branching fractions are set to be B(Λc+→Λπ+π−e+νe)

Abstract

We report a search for a dark photon using 14.9 fb−1 of e+e− annihilation data taken at center-of-mass energies from 4.13 to 4.60 GeV with the BESIII detector operated at the BEPCII storage ring. The dark photon is assumed to be produced in the radiative annihilation process of e+e− and to predominantly decay into light dark matter particles, which escape from the detector undetected. The mass range from 1.5 to 2.9 GeV is scanned for the dark photon candidate, and no significant signal is observed. The mass dependent upper limits at the 90% confidence level on the coupling strength parameter ϵ for a dark photon coupling with an ordinary photon vary between 1.6×10−3 and 5.7×10−3.

Abstract

We search for an axion-like particle (ALP) a through the process ψ(3686)→π+π−J/ψ, J/ψ→γa, a→γγ in a data sample of (2.71±0.01)×109 ψ(3686) events collected by the BESIII detector. No significant ALP signal is observed over the expected background, and the upper limits on the branching fraction of the decay J/ψ→γa and the ALP-photon coupling constant gaγγ are set at 95% confidence level in the mass range of 0.165≤ma≤2.84GeV/c2. The limits on B(J/ψ→γa) range from 8.3×10−8 to 1.8×10−6 over the search region, and the constraints on the ALP-photon coupling are the most stringent to date for 0.165≤ma≤1.468GeV/c2.

Abstract

Recent declines in male fertility, as evidenced by decreased sperm counts, in industrialized nations have been attributed partly to the exposure of men to environmental toxicants, such as cadmium, bisphenol A, and others. These environmental toxicants are found in drinking water, food, dairy products, and many utensils (e.g., plastics and glass bottles). It is of interest to note that while animal models clearly show effects of environmental toxicants on male reproductive function, linking specific environmental exposures in humans to adverse effects on the male reproductive system is very tenuous for the vast majority of environmental chemicals since human exposure is often orders of magnitude lower than dose levels used in animal studies. Nonetheless, environment toxicants have become an integrated part of our day-to-day routine and food/water intakes. This thus sparks interest in the field to assess if acute and chronic exposure of these toxicants to laboratory animals would cause reproductive damage, and whether such damage can be reversed and/or rescued. In this review, we summarize recent findings in the field regarding damage that are caused by these toxicants to the testis via their actions at the cell–cell interface, thereby inducing premature loss of germ cells from the seminiferous epithelium which leads to reduced sperm counts in semen. Some of these studies have identified specific signaling pathways that are used by these toxicants to induce disruption at the Sertoli–Sertoli and/or Sertoli–germ cell interface, perturbing the blood–testis barrier (BTB) function and germ cell adhesion. This information should be helpful in future studies to design compounds that can ‘reverse’ and/or ‘reduce’ toxicant toxicity to the testis.

Abstract

Using e+e− collision data at ten center-of-mass energies between 2.644 and 3.080 GeV collected with the BESIII detector at BEPCII and corresponding to an integrated luminosity of about 500 pb−1, we measure the cross sections and effective form factors for the process e+e−→Ξ0Ξ¯0 utilizing a single-tag method. A fit to the cross section of e+e−→Ξ0Ξ¯0 with a pQCD-driven power function is performed, from which no significant resonance or threshold enhancement is observed. In addition, the ratio of cross sections for the processes e+e−→Ξ−Ξ¯+ and Ξ0Ξ¯0 is calculated using recent BESIII measurement and is found to be compatible with expectation from isospin symmetry.

Abstract

Using 5.9 pb−1 of e+e− annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e+e−→KS0X (where X=anything). From a fit to these observed cross sections with the sum of continuum and ψ(3686) and J/ψ Breit-Wigner functions and considering initial state radiation and the BEPCII beam energy spread, we obtain for the first time the product of ψ(3686) leptonic width and inclusive decay branching fraction Γψ(3686)eeB(ψ(3686)→KS0X)=(373.8±6.7±20.0) eV, and assuming Γψ(3686)ee is (2.33±0.04) keV from PDG value, we measure B(ψ(3686)→KS0X)=(16.04±0.29±0.90)%, where the first uncertainty is statistical and the second is systematic.

Abstract

The electromagnetic process e+e−→pp¯ is studied with the initial-state-radiation technique using 7.5 fb−1 of data collected by the BESIII experiment at seven energy points from 3.773 to 4.600 GeV. The Born cross section and the effective form factor of the proton are measured from the production threshold to 3.0 GeV/c2 using the pp¯ invariant-mass spectrum. The ratio of electric and magnetic form factors of the proton is determined from the analysis of the proton-helicity angular distribution.

Abstract

Background: Short-term follow-up of COVID-19 patients reveals pulmonary dysfunction, myocardial damage and severe psychological distress. Little is known of the burden of these sequelae, and there are no clear recommendations for follow-up of COVID-19 patients.In this multi-disciplinary evaluation, cardiopulmonary function and psychological impairment after hospitalization for COVID-19 are mapped. Methods: We evaluated patients at our outpatient clinic 6 weeks after discharge. Cardiopulmonary function was measured by echocardiography, 24-hours ECG monitoring and pulmonary function testing. Psychological adjustment was measured using questionnaires and semi-structured clinical interviews. A comparison was made between patients admitted to the general ward and Intensive care unit (ICU), and between patients with a high versus low functional status. Findings: Eighty-one patients were included of whom 34 (41%) had been admitted to the ICU. New York Heart Association class II-III was present in 62% of the patients. Left ventricular function was normal in 78% of patients. ICU patients had a lower diffusion capacity (mean difference 12,5% P = 0.01), lower forced expiratory volume in one second and forced vital capacity (mean difference 14.9%; P

Abstract

In Ref. [1] the BESIII collaboration published a cross section measurement of the process e+e−→π+π− in the energy range between 600 and 900 MeV. In this corrigendum, we report a corrected evaluation of the statistical errors in terms of a fully propagated covariance matrix. The correction also yields a reduced statistical uncertainty for the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon, which now reads as aμππ,LO(600−900MeV)=(368.2±1.5stat±3.3syst)×10−10. The central values of the cross section measurement and of aμππ,LO, as well as the systematic uncertainties remain unchanged.

Abstract

A 45-year-old man with left renal mass underwent nephrectomy to reveal a 20-cm tumor diagnosed as sarcomatoid chromophobe renal cell carcinoma. Lymph node metastasis of chromophobe and sarcomatoid components, disseminated tumor in retroperitoneal fat, lymphatic vessels, and perirenal adipose tissue in lymphangitic carcinomatosis pattern were identified. Chromophobe epithelial cells were positive for epithelial membrane antigen, c-Kit, and cytokeratin 7; sarcomatoid cells were positive for CD10 and smooth muscle antigen with high proliferation index. Chromophobe epithelial cells had loss of heterozygosity in chromosomes 1p and 1q, whereas sarcomatoid cells had loss of heterozygosity in 3p, 1p, and 1q. In conclusion, sarcomatoid chromophobe renal cell carcinoma has aggressive biologic behavior and potential to metastasize in unusual patterns. Keywords: Renal cell carcinoma, Chromophobe, Sarcomatoid, Lymphangitic carcinomatosis, Lymph node metastasis
