Completely unknown before the 90s and exceptional up to the 2000s, BK virus nephropathy (BKvN), usually known as polyomavirus-associated nephropathy, has emerged as a significant and severe viral complication in kidney transplantation (KT). More than twenty years after Gardner's discovery of BKv in 1971, Purighalla described, in 1995, the first case of BKvN. Four years later in 1999, Nickeleit et al. published a first series of five cases of BKvN and made very precious and pertinent contributions to understanding t [...]

Regenerating injured nerves is difficult because they have little spontaneous regeneration potential. Advances in tissue engineering and regenerative medicine have emphasized the possibility of biomaterial-based methods for nerve healing. Natural protein-based biomaterials have benefits over synthetic ones, such as biocompatibility, non-immunogenicity, and biodegradability. Silk fibroin, generated from mulberry and non-mulberry silkworms, is especially promising because of its abundance, simplicity of processing in [...]

This study evaluated the impact on student and staff well-being of a mindfulness-based cognitive-behavioral coping program, Be REAL (Resilient Attitudes & Living), delivered by campus staff using a task-sharing approach. The program was adapted for online delivery during COVID19. Study participants included 325 undergraduate students and 100 staff members at a large tri-campus university in the U.S. Participants completed surveys with self-report measures assessing mindfulness, perceptions of stress, emotion regula [...]

The research described the production and characterization of various materials, particularly alpha-alumina ceramic supports, zeolite SAPO-34, and zeolite membranes. Ceramic supports were manufactured through dry uniaxial compaction. Sintering of the supports was carried out at 1300°C for 2 h. SAPO-34 zeolites and zeolite membranes were synthesized through a hydrothermal process involving two steps: a first step at 38°C for 24 h and a second step at 200°C for 24 h. The research aimed to determine how different sili [...]

Celiac disease (CD) is a multisystem immune-mediated disorder resulting in enteropathy of the small intestine with the ingestion of gluten, in genetically susceptible individuals. This condition impact 1% of the population and can result in the development of other conditions such as chronic fatigue, anemia, osteoporosis, aphthous stomatitis, elevated liver enzymes, joint pain, infertility, peripheral neuropathy, and epilepsy. In this review, we outline the clinical presentation of CD, the physiological differences [...]

The current state-of-the-art quantum mechanics methodologies were applied to derive information on the bulk and surface properties of the P2-type layered oxide Na0.85Li0.17Ni0.21Mn0.64O2 (NLNMO), a cathode material. The special quasi-random structure (SQS) approach was employed to identify the arrangement of Li, Ni, and Mn ions in a supercell containing 115 atoms. Both the cell parameters and atomic positions were determined from DFT-PBE+U calculations to highlight specific distortions induced by the dopants (Ni an [...]

Cancer development and progression is strongly associated with somatic mutations. From oncogenic hits that initiate the primary tumor formation to metastasis, the tumor mutational burden (TMB) plays a prominent role in the disease progression for the vast majority of cancer types. Not only are heterogeneous mutational loads or genetic heterogeneity causal to transcriptomic and proteomic discrepancies and to phenotypic diversity between individuals, they are also between tumor cells. But in addition to mutations, a [...]

A series of novel Bi2MoO6/Ag/Ag2CrO4 heterostructure photocatalysts (denoted as BA-X, X = 1, 3, 5, 10) were synthesized using a coprecipitation method. These photocatalysts were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-vis spectroscopy, and X-ray photoelectron spectroscopy (XPS) and their photocatalytic properties were investigated. Compared with pure Bi2MoO6 or Ag2CrO4, BA-5 exhibited a higher photocatalytic property and broader light absorption. In addition, the surface pla [...]

Prenatal genetic aneuploidy screening approaches are designed to identify pregnant patients at increased risk of having a fetus affected. Conventional prenatal screening has consisted in providing women a risk estimate of having a pregnancy affected with trisomy 21 or trisomy 18 based on maternal age and analysis of serum markers and ultrasound nuchal translucency (NT) measurement. In 2011, the introduction of cell-free DNA (cfDNA) based screening into clinical practice has provided new options for aneuploidy scree [...]

The current article addresses the working memory constraints experienced by older people in caregiving training. Two different approaches aiming to free the older people’s working memory space were discussed. They include multi-modal visual processing and Gc activation. The emphasis was on the theoretical underpinnings of both approaches with empirical evidence from the research and literature to demonstrate their effectiveness in older people’s caregiving training. Further discussion was made with respect to the t [...]
