Haemodynamic effects of PAH-targeted therapies in pulmonary hypertension due to lung disease: A systematic review and meta-analysis.

Pulm Pharmacol Ther 2021 May 9:102036. Epub 2021 May 9.

Department of Cardiology, AHEPA University Hospital, Thessaloniki, Greece. Electronic address:

Background: Pulmonary hypertension (PH) is a negative predictor in patients with lung disease and/or hypoxia (group 3 PH). Current guidelines do not endorse the use of targeted therapies for pulmonary arterial hypertension (PAH) in patients with group 3 PH, due to lack of strong evidence. However, a variety of studies have examined the effect of PAH-targeted therapies in group 3 PH with mixed methods and conflicting results. Read More

A Global Vista of the Epigenomic State of the Mouse Submandibular Gland.

J Dent Res 2021 May 12:220345211012000. Epub 2021 May 12.

Department of Biochemistry, Jacobs School of Medicine and Biomedical Sciences, State University of New York at Buffalo, Buffalo, NY, USA.

The parotid, submandibular, and sublingual glands represent a trio of oral secretory glands whose primary function is to produce saliva, facilitate digestion of food, provide protection against microbes, and maintain oral health. While recent studies have begun to shed light on the global gene expression patterns and profiles of salivary glands, particularly those of mice, relatively little is known about the location and identity of transcriptional control elements. Here we have established the epigenomic landscape of the mouse submandibular salivary gland (SMG) by performing chromatin immunoprecipitation sequencing experiments for 4 key histone marks.

Dual contrast agents for fluorescence and photoacoustic imaging: evaluation in a murine model of prostate cancer.

Nanoscale 2021 May 12. Epub 2021 May 12.

Russell H. Morgan Department of Radiology and Radiological Science, Johns Hopkins University, Baltimore, MD 21218, USA.

Prostate-specific membrane antigen (PSMA) is a promising diagnostic and therapeutic target for prostate cancer (PC). Poly(amidoamine) [PAMAM] dendrimers serve as versatile scaffolds for imaging agents and drug delivery that can be tailored to different sizes and compositions depending upon the application. We have developed PSMA-targeted PAMAM dendrimers for real-time detection of PC using fluorescence (FL) and photoacoustic (PA) imaging. Read More

Limited brain metastases: a narrative review.

Ann Palliat Med 2021 Apr 26. Epub 2021 Apr 26.

Department of Radiation Oncology, University Hospitals Cleveland Medical Center, Cleveland, OH, USA; Case Western Reserve University School of Medicine, Cleveland, OH, USA.

Limited brain metastases refer to an oligometastatic state in the brain for which focal therapy with stereotactic radiosurgery (SRS) is appropriate. The definition of what is considered "limited" for brain metastases, however, is not well defined. Multiple recent randomized trials show that metastasis-directed therapy with surgery or stereotactic radiation can prolong survival for patients with 1-5 metastases from various primary tumors, but patients with untreated brain metastases were largely excluded from these trials.

A pilot study on exertional tasks with physiological measures designed for the assessment of military concussion.

Concussion 2021 Apr 9;6(1):CNC88. Epub 2021 Apr 9.

Department of Allied Health Sciences, Curriculum in Human Movement Science, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA.

Background: Guidelines for clinicians treating military concussion recommend exertional testing before return-to-duty, yet there is currently no standardized task or inclusion of an objective physiological measure like heart rate variability (HRV).

Methodology & Results: We pilot-tested two clinically feasible exertional tasks that include HRV measures and examined reliability of a commercially available heart rate monitor. Testing healthy participants confirmed that the 6-min step test and 2-min pushup test evoked the targeted physiological response, and the Polar H10 was reliable to the gold-standard electrocardiogram.

Combining radiomic phenotypes of non-small cell lung cancer with liquid biopsy data may improve prediction of response to EGFR inhibitors.

Sci Rep 2021 May 11;11(1):9984. Epub 2021 May 11.

Department of Radiology, University of Pennsylvania, Philadelphia, PA, 19104, USA.

Among non-small cell lung cancer (NSCLC) patients with therapeutically targetable tumor mutations in epidermal growth factor receptor (EGFR), not all patients respond to targeted therapy. Combining circulating-tumor DNA (ctDNA), clinical variables, and radiomic phenotypes may improve prediction of EGFR-targeted therapy outcomes for NSCLC. This single-center retrospective study included 40 EGFR-mutant advanced NSCLC patients treated with EGFR-targeted therapy. Read More

The liver metastatic niche: modelling the extracellular matrix in metastasis.

Dis Model Mech 2021 Apr 15;14(4). Epub 2021 Apr 15.

CRUK Beatson Institute, Switchback Road, Bearsden, Glasgow G61 1BD, UK.

Dissemination of malignant cells from primary tumours to metastatic sites is a key step in cancer progression. Disseminated tumour cells preferentially settle in specific target organs, and the success of such metastases depends on dynamic interactions between cancer cells and the microenvironments they encounter at secondary sites. Two emerging concepts concerning the biology of metastasis are that organ-specific microenvironments influence the fate of disseminated cancer cells, and that cancer cell-extracellular matrix interactions have important roles at all stages of the metastatic cascade.

oColonic delivery of metronidazole-loaded capsules for local treatment of bacterial infections: a clinical pharmacoscintigraphy study.

Eur J Pharm Biopharm 2021 May 7. Epub 2021 May 7.

Clinical Pharmacology & Toxicology, University Hospital Basel, Basel, Switzerland.

Drug delivery to the colon offers great promise for local treatment of colonic diseases as it allows bypassing systemic absorption in the small intestine, thereby increasing luminal drug concentrations in the colon. The primary objective of this in vivo pharmaco-scintigraphy study was to assess the colon drug targeting accuracy of a metronidazole benzoate colonic drug delivery system intended for local treatment of Clostridioides difficile infections. Additionally, it was assessed if the concept of mucoadhesion would increase colonic residence time and promote higher drug bioavailability. Read More

Blue Ridge Institute for Medical Research 3754 Brevard Road, Suite 116, Box 19 Horse Shoe, North Carolina 28742-8814, United States. Electronic address:

Dysregulation and mutations of protein kinases play causal roles in many diseases including cancer. The KLIFS (kinase-ligand interaction fingerprint and structure) catalog includes 85 ligand binding-site residues occurring in both the small and large protein kinase lobes. Except for allosteric inhibitors, all FDA-approved drug-target enzyme complexes display hydrophobic interactions involving catalytic spine residue-6 (KLIFS-77), catalytic spine residue-7 (KLIFS-11), and catalytic spine residue-8 (KLIFS-15) within the small lobe and residues within the hinge-linker region (KLIFS-46-52).

Lancet Gastroenterol Hepatol 2021 May 7. Epub 2021 May 7.

Department of Intervention, Fujian Cancer Hospital, Fuzhou, China.

Background: Inhibition of vascular endothelial growth factor receptor (VEGFR) has shown antitumour activity in advanced hepatocellular carcinoma, but few studies of VEGFR inhibitors have been done in populations with a high prevalence of hepatitis B virus infection.
