Generation of macrophages with altered viral sensitivity from genome-edited rhesus macaque iPSCs to model human disease.

Mol Ther Methods Clin Dev 2021 Jun 17;21:262-273. Epub 2021 Mar 17.

Shin Kaneko Laboratory, Department of Cell Growth and Development, Center for iPS Cell Research and Application (CiRA), Kyoto University, Kyoto, Japan.

Because of their close biological similarity to humans, non-human primate (NHP) models are very useful for the development of induced pluripotent stem cell (iPSC)-based cell and regenerative organ transplantation therapies. However, knowledge on the establishment, differentiation, and genetic modification of NHP-iPSCs, especially rhesus macaque iPSCs, is limited. We succeeded in establishing iPSCs from the peripheral blood of rhesus macaques (Rh-iPSCs) by combining the Yamanaka reprograming factors and two inhibitors (GSK-3 inhibitor [CHIR 99021] and MEK1/2 inhibitor [PD0325901]) and differentiated the cells into functional macrophages through hematopoietic progenitor cells.

"What did you do this weekend?" Relationships between weekend activities, recovery experiences, and changes in work-related well-being.

Appl Psychol Health Well Being 2021 Apr 17. Epub 2021 Apr 17.

Univ. Grenoble Alpes, SENS, Grenoble, France.

Recovery refers to the process of replenishing resources that occurs when employees distance themselves from their work, leading to improvements in work-related well-being indicators (WRWB), such as burnout and vigor. Research has shown that weekend activities are related to changes in WRWB and that recovery experiences could mediate these relationships. This study aimed to examine the indirect relationships of recovery activities on changes in burnout and vigor, through weekend recovery experiences. Read More

Perception and Belief on Cannabinoids: A Comparative Study of Rheumatology Patients and Primary Care Physicians on the Use of Cannabinoids for Pain Management.

Cureus 2021 Mar 7;13(3):e13756. Epub 2021 Mar 7.

Medicine, College of Life Sciences, Leicester Medical School, University of Leicester, Leicester, GBR.

Introduction With the recent increase in popularity of cannabinoids in the management of chronic pain, the inquisitiveness among our patients and health care professionals are probably now at its peak. Many treating health care professionals in their clinical practice come across patients who either use cannabinoids or are interested in their efficacy and side effects. As there is paucity of data and research about their use in rheumatology, patient's self-reported responses and experience of primary care physicians (General Practitioners [GPs]) can guide in expanding our knowledge.

Chlorpyrifos pesticide promotes oxidative stress and increases inflammatory states in BV-2 microglial cells: A role in neuroinflammation.

Chemosphere 2021 Mar 29;278:130417. Epub 2021 Mar 29.

Department of Morphology, Federal University of Santa Maria, Santa Maria, RS, Brazil. Electronic address:

The exposure to environmental stressors, such as organophosphate (OP) pesticides, has been associated with the development of neurodegenerative diseases. Chlorpyrifos (CPF) is the worldwide most used OP pesticide and one of the most hazardous pesticides as it can cross the blood-brain barrier. Since studies evaluating the effects of CPF on brain immune cells are scarce, this research investigated the oxidative and inflammatory responses of CPF exposure in murine microglial cells.

Tackling Diversity in Prostate Cancer Clinical Trials: A Report From the Diversity Working Group of the IRONMAN Registry.

JCO Glob Oncol 2021 Apr;7:495-505

Moffitt Cancer Center, Tampa, FL.

Prostate cancer disproportionately affects racial and ethnic minority populations. Reasons for disparate outcomes among minority patients are multifaceted and complex, involving factors at the patient, provider, and system levels. Although advancements in our understanding of disease biology have led to novel therapeutics for men with advanced prostate cancer, including the introduction of biomarker-driven therapeutics, pivotal translational studies and clinical trials are underrepresented by minority populations.

The History of Gene Hunting in Hereditary Spinocerebellar Degeneration: Lessons From the Past and Future Perspectives.

Front Genet 2021 23;12:638730. Epub 2021 Mar 23.

Institut du Cerveau, INSERM U1127, CNRS UMR7225, Sorbonne Université, Paris, France.

Hereditary spinocerebellar degeneration (SCD) encompasses an expanding list of rare diseases with a broad clinical and genetic heterogeneity, complicating their diagnosis and management in daily clinical practice. Correct diagnosis is a pillar for precision medicine, a branch of medicine that promises to flourish with the progressive improvements in studying the human genome. Discovering the genes causing novel Mendelian phenotypes contributes to precision medicine by diagnosing subsets of patients with previously undiagnosed conditions, guiding the management of these patients and their families, and enabling the discovery of more causes of Mendelian diseases.

Towards improving community pharmacy-based mental health services in Nigeria.

J Pharm Policy Pract 2021 Apr 7;14(1):34. Epub 2021 Apr 7.

Department of Public Health, Mount Kenya University Rwanda, Kigali, Rwanda.

In Nigeria, there is a prevalence of aversive life circumstances that frequently assail the mental health and well-being of the citizens, mitigating the impact of which necessitates the institution of psychotherapy and other mental health care methods. These responsibilities, however, appear to be much more for pharmacists in low-resource settings where they are the most accessible healthcare professional. Some of these responsibilities include patient confidentiality as well as counseling patients on medication use, lifestyle as well as other personal matters that may arise in relation to their health.

Data silos are undermining drug development and failing rare disease patients.

Orphanet J Rare Dis 2021 Apr 7;16(1):161. Epub 2021 Apr 7.

Department of Medicine, Orphan Disease Center, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, 19104, USA.

Data silos are proliferating while research and development activity explode following genetic and immunological advances for many clinically described disorders with previously unknown etiologies. The latter event has inspired optimism in the patient, clinical, and research communities that disease-specific treatments are on the way. However, we fear the tendency of various stakeholders to balkanize databases in proprietary formats, driven by current economic and academic incentives, will inevitably fragment the expanding knowledge base and undermine current and future research efforts to develop much-needed treatments.

BEExact: a Metataxonomic Database Tool for High-Resolution Inference of Bee-Associated Microbial Communities.

mSystems 2021 Apr 6;6(2). Epub 2021 Apr 6.

Department of Microbiology & Immunology, The University of Western Ontario, London, Ontario, Canada

High-throughput 16S rRNA gene sequencing technologies have robust potential to improve our understanding of bee (Hymenoptera: Apoidea)-associated microbial communities and their impact on hive health and disease. Despite recent computation algorithms now permitting exact inferencing of high-resolution exact amplicon sequence variants (ASVs), the taxonomic classification of these ASVs remains a challenge due to inadequate reference databases. To address this, we assemble a comprehensive data set of all publicly available bee-associated 16S rRNA gene sequences, systematically annotate poorly resolved identities via inclusion of 618 placeholder labels for uncultivated microbial dark matter, and correct for phylogenetic inconsistencies using a complementary set of distance-based and maximum likelihood correction strategies.
