Relationship between DNA mismatch repair and CRISPR/Cas9-mediated knock-in in the bovine β-casein gene locus.

Anim Biosci 2021 Jun 24. Epub 2021 Jun 24.

Department of Animal Science, Chonnam National University, Gwangju 61186, Korea.

Objective: Efficient gene editing technology is critical for successful knock-in in domestic animals. RAD51 gene plays an important role in strand invasion during homologous recombination (HR) in mammals, and is regulated by CHK1 and CHK2 genes, which are upstream elements of RAD51. In addition, mismatch repair (MMR) system is inextricably linked to HR-related pathways and regulates HR via heteroduplex rejection. Read More

J Osteopath Med 2021 Jul 22. Epub 2021 Jul 22.

Division of Child & Adolescent Psychiatry, The Johns Hopkins Hospital, 1800 Orleans St, Baltimore, MD21287-0010, USA.

In 1998, a seminal study identified a strong connection between participants' exposures to adverse childhood experiences (ACEs) and the development of risk factors for serious health conditions later in life. More than two decades later, leaders in both policy and health care professions now appreciate the impact of social determinants of health, including the enormous societal costs incurred by deleterious experiences, and recognize that treating illness begins with prevention in early childhood. The trauma informed care (TIC) model offers a treatment approach that lends consideration to the traumatic experiences that impact a given patient and allows for more complete treatment by their physician.

Functional Outcomes and Return to Sport After Cartilage Restoration of the Knee in High-level Athletes.

J Am Acad Orthop Surg 2021 Jul 22. Epub 2021 Jul 22.

From the Department of Orthopaedic Surgery, Kaiser Permanente, Los Angeles, CA (Mehran), the Department of Orthopaedic Surgery, Harbor-UCLA Medical Center, Torrance, CA (Singla), the Department of Orthopaedic Surgery, Mayo Clinic, Rochester, MN (Okoroha), and the Orthopaedic Surgery and Sports Medicine, Gundersen Health System, Onalaska, WI (Mitchell).

Articular cartilage injuries of the knee are being observed with increasing frequency in athletes and have proven to be difficult to treat given the limited regenerative ability of cartilage and the potential for progressive joint degeneration. A wide range of surgical treatments such as microfracture, autologous chondrocyte implantation, and osteochondral autograft and allograft have demonstrated promising results in these high-demand individuals. These procedures permit healing of cartilage defects while decreasing pain and restoring function with patient-reported outcomes demonstrating significant improvement at short-, mid-, and long-term follow-up.

Complexities at the Au/ZrS(001) interface probed by X-ray photoemission spectroscopy.

J Phys Condens Matter 2021 Jul 22. Epub 2021 Jul 22.

Department of Physics and Astronomy and Center for Materials Research and Analysis, University of Nebraska- Lincoln, Jorgensen Hall, 855 North 16th Str., NE 68588-0299, Lincoln, 68588-0299, UNITED STATES.

Interaction between the Au adlayers and ZrS(001) has been examined via X-ray photoemission spectroscopy (XPS). The angle-resolved XPS (ARXPS) measurements reveal that ZrS(001) is disulfide (S) terminated and the Au thickness-dependent XPS indicates that the observed band bending, for low Au coverage, is consistent with formation of a Schottky barrier at the Au/ZrS(001) interface. This band bending, however, appears to be suppressed as the thickness of Au adlayer is increased, indicating varying interfacial interactions at the Au/ZrS(001) interface. Read More

Direct in vivo reprogramming with non-viral sequential targeting nanoparticles promotes cardiac regeneration.

Biomaterials 2021 Jul 15;276:121028. Epub 2021 Jul 15.

Department of Cardiology, Zhongshan Hospital, Fudan University. Shanghai Institute of Cardiovascular Diseases, Shanghai, 20032, China; Institute of Biomedical Sciences, Fudan University, Shanghai, 20032, China. Electronic address:

microRNA-mediated direct cardiac reprogramming, directly converts fibroblasts into induced cardiomyocyte-like cells (iCMs), which holds great promise in cardiac regeneration therapy. However, effective approaches to deliver therapeutic microRNA into cardiac fibroblasts (CFs) to induce in vivo cardiac reprogramming remain to be explored. Herein, a non-viral biomimetic system to directly reprogram CFs for cardiac regeneration after myocardial injury was developed by coating FH peptide-modified neutrophil-mimicking membranes on mesoporous silicon nanoparticles (MSNs) loaded with microRNA1, 133, 208, and 499 (miR Combo).

High salt seriously destroys the stable interactions among key functional species of activated sludge, which in turn limits the performance of high-salinity wastewater biological treatment. In this study, pelletized Aspergillus tubingensis (AT) was used as a protective backbone structure for activated sludge under high-salinity stress, and a superior salt-tolerant AT-based aerobic granular sludge (AT-AGS) was developed. Results showed that the COD and NH-N removal efficiencies of salt-domesticated AT-AGS were 11. Read More

Inconsistent idealizations and inferentialism about scientific representation.

Authors:
Peter Tan

Stud Hist Philos Sci 2021 Jul 19;89:11-18. Epub 2021 Jul 19.

Fordham University, Department of Philosophy, Lowenstein 916C, 113 W. 60th St, New York, NY 10023, USA. Electronic address:

Inferentialists about scientific representation hold that an apparatus's representing a target system consists in the apparatus allowing "surrogative inferences" about the target. I argue that a serious problem for inferentialism arises from the fact that many scientific theories and models contain internal inconsistencies. Inferentialism, left unamended, implies that inconsistent scientific models have unlimited representational power, since an inconsistency permits any conclusion to be inferred. Read More

Color discrimination in anomalous trichromacy: Experiment and theory.

Vision Res 2021 Jul 19;188:85-95. Epub 2021 Jul 19.

Department of Psychology, University of California, San Diego, CA, USA.

In anomalous trichromacy, the color signals available from comparing the activities of the two classes of cone sensitive in the medium and long wavelength parts of the spectrum are much reduced from those available in normal trichromacy, and color discrimination thresholds along the red-green axis are correspondingly elevated. Yet there is evidence that suprathreshold color perception is relatively preserved; this has led to the suggestion that anomalous trichromats post-receptorally amplify their impoverished red-green signals. To test this idea, we measured chromatic discrimination from white and from saturated red and green pedestals. Read More

Department of Molecular and Human Genetics, Institute of Science, Banaras Hindu University, Varanasi, 221005, India. Electronic address:

Synergistic interplay of immune endocrine interaction is prerequisite for an effective maternal fetal tolerance. Pre-term birth (PTB) may be a consequence of altered immune-endocrine crosstalk during third trimester resulting in early breakdown of this tolerance. Myeloid derived suppressor cells (MDSCs), a heterogenous population of immature immune cells are increased in pregnant women and healthy newborns, but their role in PTB still remains obscure.
