[Ophthalmic safety profile of antiangiogenic therapy].

Vestn Oftalmol 2021 ;137(2):114-122

Novosibirsk State Region Hospital, Novosibirsk, Russia.

Antiangiogenic therapy with inhibitors of vascular endothelial growth factor (anti-VEGF) has not only fundamentally changed the treatment outcomes of vasoproliferative eye diseases, but also became the most common ophthalmic surgical manipulation. At the same time, in 36-48% of bilateral lesions there is a need to perform injections in both eyes, making relevant the issues of safety and prevention of severe complications that threaten irreversible loss of visual function. The article reviews the results of randomized clinical trials and real clinical practice, analyzes the incidence and causes of its most dangerous complication - endophthalmitis, characterizes the clinical course depending on the type of drug used, and considers the possibility of reducing the risk of this complication occurring.

Multilayered Human Skeletal Muscle Myoblast Sheets Promote the Healing Process After Colonic Anastomosis in Rats.

Cell Transplant 2021 Jan-Dec;30:9636897211009559

Cardiovascular Research Institute, 13155Yokohama City University, Yokohama, Kanagawa, Japan.

Colorectal anastomotic leakage is one of the most feared and fatal complications of colorectal surgery. To date, no external coating material that can prevent anastomotic leakage has been developed. As myoblasts possess anti-inflammatory capacity and improve wound healing, we developed a multilayered human skeletal muscle myoblast (HSMM) sheet by periodic exposure to supraphysiological hydrostatic pressure during repeated cell seeding.

Physiologists turned Geneticists: Identifying transcripts and genes for neuronal function in the Marbled Crayfish, .

J Undergrad Neurosci Educ 2020 31;19(1):A36-A51. Epub 2020 Dec 31.

School of Biological Science, Illinois State University, Normal, IL 61790.

The number of undergraduate researchers interested in pursuing neurophysiological research exceeds the research laboratory positions and hands-on course experiences available because these types of experiments often require extensive experience or expensive equipment. In contrast, genetic and molecular tools can more easily incorporate undergraduates with less time or training. With the explosion of newly sequenced genomes and transcriptomes, there is a large pool of untapped molecular and genetic information which would greatly inform neurophysiological processes.

Decision support for the quickest detection of critical COVID-19 phases.

Sci Rep 2021 Apr 20;11(1):8558. Epub 2021 Apr 20.

Department of Electrical and Computer Engineering, University of Connecticut, Storrs, 06269, USA.

During the course of an epidemic, one of the most challenging tasks for authorities is to decide what kind of restrictive measures to introduce and when these should be enforced. In order to take informed decisions in a fully rational manner, the onset of a critical regime, characterized by an exponential growth of the contagion, must be identified as quickly as possible. Providing rigorous quantitative tools to detect such an onset represents an important contribution from the scientific community to proactively support the political decision makers. Read More

A three-time point longitudinal investigation of the arcuate fasciculus throughout reading acquisition in children developing dyslexia.

Neuroimage 2021 Apr 17:118087. Epub 2021 Apr 17.

Parenting and Special Education Research Unit, Faculty of Psychology and Educational Sciences, KU Leuven, Belgium; Research Group ExpORL, Department of Neurosciences, KU Leuven, Belgium; Psychological Sciences Research Institute, Université Catholique de Louvain, Louvain-la-Neuve, Belgium; Institute of Neuroscience, Université Catholique de Louvain, 1348 Louvain-la-Neuve, Belgium. Electronic address:

Although the neural basis of dyslexia has intensively been investigated, results are still unclear about the existence of a white matter deficit in the arcuate fasciculus (AF) throughout development. To unravel this ambiguity, we examined the difference in fractional anisotropy (FA) of the AF between children developing dyslexia and children developing typical reading skills in a longitudinal sample with three MRI time points throughout reading development: the pre-reading stage (5-6 years old), the early reading stage (7-8 years old) and the advanced reading stage (9-10 years old). Applying along-the-tract analyses of white matter organization, our results confirmed that a white matter deficit existed in the left AF prior to the onset of formal reading instruction in children who developed dyslexia later on.

Comparative profile of refractory status epilepticus models following exposure of cholinergic agents pilocarpine, DFP, and soman.

Neuropharmacology 2021 Apr 17:108571. Epub 2021 Apr 17.

Department of Neuroscience and Experimental Therapeutics, Texas A&M University Health Science Center College of Medicine, Bryan, TX 77807.

Status epilepticus (SE) is a medical emergency with continuous seizure activity that causes profound neuronal damage, morbidity, or death. SE incidents can arise spontaneously, but mostly are elicited by seizurogenic triggers. Chemoconvulsants such as the muscarinic agonist pilocarpine and organophosphates (OP), such as the pesticide diisopropylfluorophosphate (DFP) and the nerve agent soman, can induce SE. Read More

Cases of Q fever detected in residents of the novosibirsk region hospitalized with suspection of infections transmitted by ticks.

Klin Lab Diagn 2021 Apr;66(4):229-236

Institute of Chemical Biology and Fundamental Medicine SB RAS.

Coxiella burnetii is the causative agent of Q fever (coxiellosis), which, in addition to acute manifestations, often occurs in a latent form, is prone to chronic course and, in the absence of antibiotic therapy, has a high risk of disability or death. As a result of the presence of a wide range of clinical manifestations specific to other infectious diseases, the use of laboratory test methods (LTM) is required to make a diagnosis. The presence of Q fever anthropurgic foci in the Novosibirsk region was described in the 90s of the last century, but due attention to its laboratory diagnostics is not paid in this region.
