J Forensic Leg Med 2018 Dec 10;61:108-114. Epub 2018 Dec 10.

Department and Biotechnology Research Center, Semnan University of Medical Sciences, Semnan, Iran. Electronic address:

Introduction: Short Tandem Repeats (STRs) are defined as short lengths of 2-7 base pairs spreading through human genome which due to their highly diverse individually distribution are widely applied for identity detection and other forensic medicine purposes. Burdening considerable costs by the conventional methods such as capillary electrophoresis, we aimed to compare concomitant usage of multiplex PCR and denaturing high-performance liquid chromatography (DHPLC) as cheap, fast, highly accurate, and more accessible methods, with capillary electrophoresis (CE) to evaluate their potential for early screening of STRs.

Materials And Methods: The present study randomly included 20 blood samples from the subjects referred to forensic medicine of Semnan, Iran. Read More

Immune cells in the retina and choroid: Two different tissue environments that require different defenses and surveillance.

Prog Retin Eye Res 2018 Dec 12. Epub 2018 Dec 12.

Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia.

In the eye immune defenses must take place in a plethora of differing microenvironments ranging from the corneal and conjunctival epithelia facing the external environment to the pigmented connective tissue of the uveal tract containing smooth muscle, blood vessels and peripheral nerves to the innermost and highly protected neural retina. The extravascular environment of the neural retina, like the brain parenchyma, is stringently controlled to maintain conditions required for neural transmission. The unique physiological nature of the neural retina can be attributed to the blood retinal barriers (BRB) of the retinal vasculature and the retinal pigment epithelium, which both tightly regulate the transport of small molecules and restrict passage of cells and macromolecules from the circulation into the retina in a similar fashion to the blood brain barrier (BBB).

Non-covalent hitchhiking on endogenous carriers as a protraction mechanism for antiviral macromolecular prodrugs.

J Control Release 2018 Dec 12. Epub 2018 Dec 12.

Department of Chemistry, Aarhus University, 8000 Aarhus C, Denmark. Electronic address:

Albumin is a highly successful tool of drug delivery providing drastically extended body and blood residence time for the associated cargo, but it only traffics single drug copies at a time. In turn, macromolecular prodrugs (MP) are advantaged in carrying a high drug payload but offering only a modest extension of residence time to the conjugated drugs. In this work, we engineer MP to contain terminal groups that bind to albumin via non-covalent association and reveal that this facile measure affords a significant protraction for the associated polymers.

Bronchiolitis obliterans after allogeneic hematopoietic stem cell transplantation: the effect of NOD2/CARD15 mutations in a Tunisian population.

Hum Immunol 2018 Dec 12. Epub 2018 Dec 12.

Immunogenetic Applied to Cells Therapy Research Unit, Immuno-Haematology and HLA-Typing Department, National Blood Transfusion Centre of Tunis, Tunis, Tunisia.

Bronchiolitis obliterans (BO) is a serious lung complication that can develop after allogenic stem cell transplantation. It has been suggested that single nucleotide polymorphisms (SNPs) that affect the NOD2/CARD15 gene impair its function and result in an uncontrolled innate immune response in the recipient, thereby leading to BO. One hundred eighty-one donor-recipient pairs were analyzed for the association between NOD2 gene variants (SNP8 [Arg702Trp], SNP12 [Gly908Arg], and SNP13 [Leu1007fsinsC]) and the occurrence of BO.

We described two distinct cell types with interlaminar processes that have been referred to as ILA, that we termed pial ILA and supial ILA. Read More

Periventricular Microglial Cells Interact with Dividing Precursor Cells in the Nonhuman Primate and Rodent Prenatal Cerebral Cortex.

J Comp Neurol 2018 Dec 15. Epub 2018 Dec 15.

Department of Pediatrics, School of Medicine, UC Davis, Davis, CA.

Cortical proliferative zones have been studied for over 100 years, yet recent data has revealed that microglial cells constitute a sizeable proportion of ventricular zone cells during late stages of cortical neurogenesis. Microglia begin colonizing the forebrain after neural tube closure and during later stages of neurogenesis populate regions of the developing cortex that include the proliferative zones. We previously showed that microglia regulate the production of cortical cells by phagocytosing neural precursor cells (NPCs), but how microglia interact with NPCs remains poorly understood.

The expression levels of miRNA-15a and miRNA-16-1 in circulating tumor cells of patients with diffuse large B-cell lymphoma.

Mol Biol Rep 2018 Dec 14. Epub 2018 Dec 14.

Department of Cancer Genetics, Istanbul Faculty of Medicine, Oncology Institute, Istanbul University, Istanbul, Turkey.

MicroRNAs (miRNAs) have major roles in nearly all cellular process including gene expression, and may behave as oncogene or tumor suppressor gene by binding to complementary sequences in the target mRNA. The circulating microRNA-15a (miRNA-15a) and microRNA-16-1 (miRNA-16-1) of 15 healthy adults and of 40 untreated patients diagnosed with diffuse large B-cell lymphoma (DLBC) were recruited to investigate the expression levels. The expression levels of miRNA-15a, and miRNA-16-1 genes of the untreated DLBCL patients, and healthy individuals with matched age, sex and ethnicity were examined. Read More

Pharmacokinetics of Prolonged-Release Once-Daily Formulations of Tacrolimus in De Novo Kidney Transplant Recipients: A Randomized, Parallel-Group, Open-Label, Multicenter Study.

Adv Ther 2018 Dec 14. Epub 2018 Dec 14.

Service de Néphrologie, Dialyse, Aphérèses et Transplantation, CHU Grenoble Alpes, Grenoble, France.

Introduction: Different prolonged-release formulations of tacrolimus are available. To date, the pharmacokinetic (PK) profile of LCP-tacrolimus (LCPT; Envarsus) has not been compared with PR-Tac (Advagraf) in de novo kidney transplant recipients. These profiles will guide clinical recommendations for the initiation and dose titration strategies of once-daily tacrolimus formulations. Read More

Tissue Plasminogen Activator Causes Brain Microvascular Endothelial Cell Injury After Oxygen Glucose Deprivation by Inhibiting Sonic Hedgehog Signaling.

Neurochem Res 2018 Dec 14. Epub 2018 Dec 14.

Department of Neurosurgery, Renmin Hospital of Wuhan University, No. 9 Zhangzhidong Road, Wuchang District, Wuhan, 430072, Hubei Province, China.

The thrombolytic activity of tissue plasminogen activator (tPA) has undisputed benefits. However, the documented neurotoxicity of tPA raises important issues. Currently, common treatments for stroke might not be optimum if exogenous tPA can pass through the blood-brain barrier and enter the brain, thus adding to the deleterious effects of tPA within the cerebral parenchyma.

No overlap between IgG4-related disease and microscopic polyangiitis and granulomatosis with polyangiitis despite elevated serum IgG4 at diagnosis: a retrospective monocentric study.

Clin Rheumatol 2018 Dec 14. Epub 2018 Dec 14.

Division of Rheumatology, Department of Internal Medicine, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea.

Objectives: We investigated whether elevated serum IgG4 at the time of diagnosis of microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) may be associated with concurrent IgG4-related disease (IgG4-RD) in immunosuppressive drug-naïve patients.

Methods: We retrospectively reviewed the medical records of 46 MPA and GPA patients with results on serum IgG4 and histology at diagnosis. Elevated serum IgG4 was defined as IgG4 > 135 mg/dL. Read More

Flow-Mediated Drug Transport from Drug-Eluting Stents is Negligible: Numerical and In-vitro Investigations.

Ann Biomed Eng 2018 Dec 14. Epub 2018 Dec 14.

UNSW Sydney, Sydney, NSW, Australia.

Prior numerical studies have shown that the blood flow patterns surrounding drug-eluting stents can enhance drug uptake in stented arteries. However, these studies employed steady-state simulations, wherein flow and drug transport parameters remained constant with respect to time. In the present study, numerical simulations and in-vitro experiments were performed to determine whether luminal blood flow patterns can truly enhance drug uptake in stented arteries. Read More
