The Lanata trichome mutation increases stomatal conductance and reduces leaf temperature in tomato.

J Plant Physiol 2021 Apr 6;260:153413. Epub 2021 Apr 6.

Departamento de Biologia Vegetal, Universidade Federal de Viçosa, CEP 36570-900, Viçosa, MG, Brazil. Electronic address:

Trichomes are epidermal structures with a large variety of ecological functions and economic applications. Glandular trichomes produce a rich repertoire of secondary metabolites, whereas non-glandular trichomes create a physical barrier on the epidermis: both operate in tandem against biotic and abiotic stressors. A deeper understanding of trichome development and function would enable the breeding of more resilient crops. Read More

Asparagine sustains cellular proliferation and c‑Myc expression in glutamine‑starved cancer cells.

Oncol Rep 2021 Jun 13;45(6). Epub 2021 Apr 13.

Institute of Molecular Genetics, Luigi Luca Cavalli‑Sforza, National Research Council, I-27100 Pavia, Italy.

During tumorigenesis, oncogene activation and metabolism rewiring are interconnected. Activated c‑ upregulates several genes involved in glutamine metabolism, making cancer cells dependent on high levels of this amino acid to survive and proliferate. After studying the response to glutamine deprivation in cancer cells, it was found that glutamine starvation not only blocked cellular proliferation, but also altered c‑Myc protein expression, leading to a reduction in the levels of the canonical c‑Myc isoform and an increase in the expression of c‑Myc 1, a c‑Myc isoform translated from an in‑frame 5' CUG codon.

Cardiac Afferent Signaling Partially Underlies Premature Ventricular Contraction-Induced Cardiomyopathy.

Heart Rhythm 2021 Apr 9. Epub 2021 Apr 9.

UCLA Cardiac Arrhythmia Center, UCLA Neurocardiology Research Program of Excellence, University of California, Los Angeles CA. Electronic address:

Background: The mechanisms underlying premature ventricular contraction (PVC)-induced cardiomyopathy remain unknown. Transient receptor potential vanilloid 1 (TRPV1) afferent fibers are implicated in the reflex processing of cardiac stress.

Objective: We aimed to determine whether cardiac TRPV1 afferent signaling promote PVC-induced cardiomyopathy. Read More

The influenza vaccine for nursing and care professionals at emergency services in Flanders.

Hum Vaccin Immunother 2021 Apr 12:1-4. Epub 2021 Apr 12.

University of Antwerp, Faculty of Medicine and Health Sciences, Master of Nursing and Midwifery, Campus Drie Eiken, Wilrijk, Belgium.

: The Belgian Superior Health Council recommends seasonal influenza vaccination for people working in the health care sector in order to reduce the risk of the influenza virus being transmitted to people at risk. The aim of this study is to provide more insight into the current vaccination rate in nurses and health care professionals in emergency services in Flanders. In addition, the influence of influenza vaccination on absenteeism will be investigated, as well as the motivation to get vaccinated or not. Read More

[Cartilage repair procedures for early osteoarthritis].

Orthopade 2021 Apr 12. Epub 2021 Apr 12.

Abteilung und Poliklinik für Sportorthopädie, Klinikum rechts der Isar, Technische Universität München, München, Deutschland.

Background: Commonly used cartilage repair procedures have been established for focal cartilage lesions; however, degenerative lesions with accompanying changes of other intraarticular structures are much more common in clinical practice. This stage, in which classic radiological signs of osteoarthritis are absent, is called early osteoarthritis and is characterized by impaired joint homeostasis with biomechanical and biochemical changes that can have a negative effect on regenerative cartilage therapy procedures.

Indication: Cartilage repair procedures are indicated for symptomatic focal early osteoarthritis, defined as cartilage degeneration ICRS grades I or II around a focal cartilage defect ICRS grades III or IV. Read More

Preoperative coronary artery calcifications in veterans predict higher all-cause mortality in early-stage lung cancer: a cohort study.

J Thorac Dis 2021 Mar;13(3):1427-1433

Department of Thoracic Surgery, Vanderbilt University Medical Center, Nashville, TN, USA.

Background: Lung cancer patients often have comorbidities that may impact survival. This observational cohort study examines whether coronary artery calcifications (CAC) impact all-cause mortality in patients with resected stage I non-small cell lung cancer (NSCLC).

Methods: Veterans with stage I NSCLC who underwent resection at a single institution between 2005 and 2018 were selected from a prospectively collected database. Read More

Thermal Stress Interacts With Surgeonfish Feces to Increase Coral Susceptibility to Dysbiosis and Reduce Tissue Regeneration.

Front Microbiol 2021 25;12:620458. Epub 2021 Mar 25.

Department of Microbiology, Oregon State University, Corvallis, OR, United States.

Dysbiosis of coral microbiomes results from various biotic and environmental stressors, including interactions with important reef fishes which may act as vectors of opportunistic microbes via deposition of fecal material. Additionally, elevated sea surface temperatures have direct effects on coral microbiomes by promoting growth and virulence of opportunists and putative pathogens, thereby altering host immunity and health. However, interactions between these biotic and abiotic factors have yet to be evaluated. Read More

Primary Failure of Autogenous Arteriovenous Fistula: Critical Analysis.

Indian J Nephrol 2020 Nov-Dec;30(6):382-390. Epub 2020 Nov 11.

Department of Plastic Surgery, Command Hospital, Kolkata, West Bengal, India.

Introduction: Permanent vascular access is an essential intervention in patients with advanced chronic kidney disease (CKD) and its success depends on various non-modifiable and modifiable factors. Considering the element of unpredictability and failure, we attempted to analyze various factors responsible for primary arteriovenous fistula (AVF) failure in presumed high-risk groups.

Materials And Methods: We conducted an observational study of newly created AVFs at a tertiary referral government hospital in Eastern India between January 2014 and June 2015. Read More

The prediction of need of using ankle-foot orthoses in stroke patients based on findings of a transcranial magnetic stimulation study.

J Integr Neurosci 2021 Mar;20(1):119-123

Department of Physical Medicine and Rehabilitation, Yeungnam University College of Medicine, 41020 Daegu, Republic of Korea.

Ankle-foot orthoses (AFOs) are widely prescribed for stroke rehabilitation. We investigated the potential of transcranial magnetic stimulation (TMS) at an early stage, after stroke, to predict the need of using AFOs in stroke patients. We recruited 35 patients who could walk with intermittent support of one person or independently 3 months after onset of stroke. Read More

Corrective osteotomy for malunion of distal diaphyseal/metaphyseal radius or ulna fracture affecting stability of the distal radioulnar joint.

Injury 2021 Apr 1. Epub 2021 Apr 1.

Department of Orthopedic Surgery, Regional Rheumatoid and Degenerative Arthritis Center, Chungnam National University Hospital, Chungnam National University School of Medicine, Daejeon, Korea.

Background: We postulated that residual distal radioulnar joint (DRUJ) instability after distal diaphyseal or metaphyseal fracture in the radius or ulna may occur due to malaligned or malunited bony structures as well as primary or secondary soft issue stabiliser. Here, we report the outcomes of corrective osteotomy in a retrospective study.

Methods: Patients undergoing the osteotomy for DRUJ instability between March 2000 and February 2018 were included in the study. Read More

Limited Evidence for Accumulation of Latent Infections of Canker-Causing Pathogens in Shoots of Stone Fruit and Nut Crops in California.

Phytopathology 2021 Apr 8. Epub 2021 Apr 8.

University of California -Davis, Department of Plant Pathology/Kearney Agric. Res. & Ext. Center, 9240 South Riverbend Ave., Parlier, California, United States, 93648;

Prevalence of latent infections of the canker-causing fungi and species of , and in young shoots of almond, prune and walnut trees in California was studied to test the hypotheses that 1) latent infections accumulate from current-season shoots to 1-year-old shoots in the orchard and 2) there are distinct associations among pathogen taxa present as latent infections in the same shoot. Samples of newly-emerged and 1-year-old shoots were periodically collected in each almond, prune, and walnut orchard for two growing seasons. A real-time quantitative PCR assay was used to quantify latent infection with three parameters: incidence, molecular severity and latent infection index. Read More
