A functional division of sweet taste neurons that is value-based and task-specific.

Proc Natl Acad Sci U S A 2022 Jan;119(3)

Department of Neurobiology, Duke University Medical School, Durham, NC 27710;

Sucrose is an attractive feeding substance and a positive reinforcer for But females have been shown to robustly reject a sucrose-containing option for egg-laying when given a choice between a plain and a sucrose-containing option in specific contexts. How the sweet taste system of promotes context-dependent devaluation of an egg-laying option that contains sucrose, an otherwise highly appetitive tastant, is unknown. Here, we report that devaluation of sweetness/sucrose for egg-laying is executed by a sensory pathway recruited specifically by the sweet neurons on the legs of First, silencing just the leg sweet neurons caused acceptance of the sucrose option in a sucrose versus plain decision, whereas expressing the channelrhodopsin in them caused rejection of a plain option that was "baited" with light over another that was not.

Strong pump rejection filter for polarization-diverse silicon platforms.

Opt Lett 2022 Jan;47(2):341-344

Integrated wavelength filters with high optical rejection are key components in several silicon photonics circuits, including quantum photon-pair sources and spectrometers. Non-coherent cascading of modal-engineered Bragg filters allows for remarkable optical rejections in structures that only support transverse-electric (TE) polarized modes such as uncladded 220-nm-thick silicon. However, the restriction to TE-only platforms limits the versatility of the non-coherent cascading approach. Read More

Cytosporone B (Csn-B), an NR4A1 agonist, attenuates acute cardiac allograft rejection by inducing differential apoptosis of CD4+T cells.

Int Immunopharmacol 2022 Jan 10;104:108521. Epub 2022 Jan 10.

Department of Cardiovascular Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. Electronic address:

CD4+T cell-mediated acute rejection remains a major factor that affects the early survival of transplanted organs post-transplantation. Here, we reveal that nuclear receptor subfamily 4 Group A member 1 (Nr4A1) was upregulated during cardiac allograft rejection and that the increased Nr4A1 was primarily localized in intragraft-infiltrating CD4+T cells. Nr4A1 acts as a transcription factor with an important role in CD4+T cell apoptosis, differentiation and T cell dysfunction, which indicates that Nr4A1 may play a critical role in transplant rejection.

J Colloid Interface Sci 2022 Jan 3;612:608-616. Epub 2022 Jan 3.

School of Chemistry and Chemical Engineering, Nanjing University, Jiangsu 210023, China; Shenzhen Research Institute of Nanjing University, Nanjing University, 581000 Shenzhen, China. Electronic address:

There is no doubt that the wide application of COFs depends on the diversity and complexity of their structure and composition, as well as the feasibility and convenience of use. Herein, large area defect-free continuous functional material layers have been fabricated by compounding sub-stoichiometric tetratopic-tritopic covalent organic frameworks (TT-COFs) on graphene oxide (GO) via simply hot pressing. The one-step synthesis of TT-COFs with built-in formyl groups endowed the robust material layers with extraordinary host-guest interactions, so they can specifically reject cations dyes according to adsorption effect, molecular sieving and Donnan effect.

Rejection sensitivity across sex, sexual orientation, and age: Measurement invariance and latent mean differences.

Psychol Assess 2022 Jan 13. Epub 2022 Jan 13.

Department of Social and Behavioral Sciences.

Intergroup differences in personality might be determined by systematic variation in social status and social experiences across groups. Because of its close association with social experiences, rejection sensitivity (RS)-a tendency toward anxious expectations of, and hypersensitivity to, interpersonal rejection-represents one such personality disposition that might differ across social groups, with implications for understanding mental health disparities. After first evaluating measurement invariance of the Adult Rejection Sensitivity Questionnaire (A-RSQ), the present research sought to assess whether latent mean differences in RS emerged across sex, sexual orientation, and age in a population-based sample of Swedish young adults (age 18-36; = 1,679).

Biological Variation of Donor-Derived Cell-Free DNA in Stable Lung Transplant Recipients.

J Appl Lab Med 2022 Jan 12. Epub 2022 Jan 12.

Laboratory of Applied Precision Omics (APO) and Genomic Research Alliance for Transplantation (GRAfT), National Institutes of Health, Bethesda, MD, USA.

Background: Prior studies demonstrate that donor-derived cell-free DNA (dd-cfDNA) in lung transplant recipients may serve as a marker of allograft injury for detecting allograft rejection and infection. Clinical interpretation of dd-cfDNA requires understanding its biological variation in stable lung transplant patients in order to identify abnormal results suggesting underlying allograft dysfunction. This study establishes the biological variation and reference change values (RCV) of dd-cfDNA in stable lung transplant recipients using an analytically validated assay with an established analytic coefficient of variation (CVA).

Conceptualizing aged reproduction: genetic connectedness, son preference and assisted reproduction in North India.

Reprod Biomed Soc Online 2022 Mar 14;14:182-191. Epub 2021 Dec 14.

Department of Liberal Arts, Indian Institute of Technology Hyderabad, Sangareddy, Telangana, India.

In this paper, I explore the narratives on the administration of assisted reproductive technology (ART) treatments amongst ageing men and women who are past their 'reproductive prime'. I use the phrase 'past their reproductive prime' with caution as ART has the capability to resurrect the desire, quest and conception of children amongst these ageing women and men. In rural agrarian Haryana in North India, ART panders to, and provides, potent narratives for perpetuation of the patrilineage for genetic continuity through the male line. Read More
