Hematological and performance adaptations to altitude training (2,320 m) in elite middle-distance and distance swimmers

Frontiers in Physiology
PurposeElite swimmers often schedule altitude training camps ahead of major events in an attempt to maximize performance. However, the relationships between altitude-induced hematological changes, markers of training adaptation, and performance changes ...

Blood–brain barrier opening in Alzheimer’s disease using MR-guided focused ultrasound

Nature Communications, 2018
Magnetic resonance-guided focused ultrasound in combination with intravenously injected microbubbles has been shown to transiently open the blood–brain barrier, and reduce beta-amyloid and tau pathology in animal models of Alzheimer’s disease.

Synthetic Vasopressin and Oxytocin Analogs and Their Potential Use in Hemorrhagic, Traumatic and Septic Shock: A Personal Perspective [PDF]

, 2017
As one of us has stated many years ago, “shock is a significant and sustained loss of effective circulating blood volume. It will eventuate in hypoperfusion of critical peripheral tissues, thus leading to a deficit in transcapillary exchange function in ...

Feasibility of a ctDNA multigenic panel for non‐small‐cell lung cancer early detection and disease surveillance

Molecular Oncology, EarlyView.
Plasma‐based detection of actionable mutations is a promising approach in lung cancer management. Analysis of ctDNA with a multigene NGS panel identified TP53, KRAS, and EGFR as the most frequently altered, with TP53 and KRAS in treatment‐naïve patients and TP53 and EGFR in previously treated patients.

Hematological Adaptations to Prolonged Heat Acclimation in Endurance-Trained Males

Frontiers in Physiology, 2019
Heat acclimation is associated with plasma volume (PV) expansion that occurs within the first week of exposure. However, prolonged effects on hemoglobin mass (Hbmass) are unclear as intervention periods in previous studies have not allowed sufficient ...

A pilot study evaluating concordance between blood-based and patient-matched tumor molecular testing within pancreatic cancer patients participating in the Know Your Tumor (KYT) initiative [PDF]

, 2016
Recent improvements in next-generation sequencing (NGS) technology have enabled detection of biomarkers in cell-free DNA in blood and may ultimately replace invasive tissue biopsies.

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Enhancing blood culture volume with ultrathin-wall cannula devices

Journal of Clinical Microbiology
Suboptimal blood volume collection negatively affects pathogen recovery and time to pathogen detection in clinical blood culture samples. This study evaluated the performance of the ultrathin-wall cannula device of the BD Vacutainer UltraTouch Push ...

Computer simulation of preflight blood volume reduction as a countermeasure to fluid shifts in space flight [PDF]

Fluid shifts in weightlessness may cause a central volume expansion, activating reflexes to reduce the blood volume. Computer simulation was used to test the hypothesis that preadaptation of the blood volume prior to exposure to weightlessness could ...
