Rosuvastatin Improves Cognitive Function of Chronic Hypertensive Rats by Attenuating White Matter Lesions and Beta-Amyloid Deposits
Hypertensive white matter lesion (WML) is one of common causes of vascular cognitive impairment. In this study, we aimed to investigate the effect of rosuvastatin on cognitive impairment and its underlying mechanisms in chronic hypertensive rats. From the 8th week after establishment of stroke-prone renovascular hypertensive rats (RHRSPs), rosuvastatin (10 mg/kg) or saline as a control was administrated once daily for consecutive 12 weeks by gastric gavage. Cognitive function was assessed with the...

A preliminary study of endothelial cell migration during angiogenesis using a meshless method approach
Abstract Angiogenesis, the development of new blood capillaries, is crucial for the wound healing process. This biological process allows the proper blood supply to the tissue, essential for cell proliferation and viability. Several biological factors modulate angiogenesis, however the vascular endothelial growth factor (VEGF) is the main one. Given the complexity of angiogenesis, in the last years, computational modelling aroused the interest of scientists since it allows to model this process...

A Parallel Non‐nested Two‐level Domain Decomposition Method for Simulating Blood Flows in Cerebral Artery of Stroke Patient
Abstract Numerical simulation of blood flows in patient‐specific arteries can be useful for the understanding of vascular diseases, as well as for surgery planning. In this paper, we simulate blood flows in the full cerebral artery of stroke patients. To accurately resolve the flow in this rather complex geometry with stenosis is challenging and it is also important to obtain the results in a short amount of computing time so that the simulation can be used in pre‐ and/or post‐surgery planning....

Smartwatch Tracks Levels of Medication in the Body for Personalized Dosing
Researchers at the UCLA Samueli School of Engineering and the Stanford School of Medicine have developed a smartwatch that uses electrochemical analysis to track levels of a drug in the body by analyzing a patient’s sweat. The system could help with finding the correct drug and dose for a given patient in order to maximize therapeutic potential and avoid side-effects. At present, most drugs are prescribed based on standard guidelines and can be tailored based on parameters such as...

Robotic Clinicians for Taking Nasal Swabs During Covid Pandemic
A cornerstone of the world’s response to Covid-19 has been mass testing of as many people as possible for the SARS-CoV-2 virus. The very act of taking a nasal swab can put a clinician performing it, or one nearby instructing the patient on how to do it, at risk. Now, a new robot has been unveiled by Brain Navi, a Taiwanese firm, that performs nasal swabs all on its own. It may make it possible to expand testing for the virus that causes Covid-19, while preventing its possible spread at the...

Prevalence of and risk factors associated with latent tuberculosis infection in a Latin American region
Tuberculosis (TB) represents a health problem in Colombia, and its control is focused on the search for contacts and treatment of TB cases underscoring the role of latent tuberculosis infection (LTBI) as a reservoir of Mycobacterium tuberculosis. The burden of LTBI in Colombia is unknown. We aimed to estimate the prevalence of LTBI and identify the associated risk factors. In this cross-sectional study, we recruited participants from four health care centers in Cali, Colombia. The participants were...

Perils and pitfalls of mixed-effects regression models in biology
Biological systems, at all scales of organisation from nucleic acids to ecosystems, are inherently complex and variable. Biologists therefore use statistical analyses to detect signal among this systemic noise. Statistical models infer trends, find functional relationships and detect differences that exist among groups or are caused by experimental manipulations. They also use statistical relationships to help predict uncertain futures. All branches of the biological sciences now embrace the possibilities...

Nectar robbing in the trainbearers (Lesbia, Trochilidae)
Many flower visitors engage in floral larceny, a suite of so-called ’illegitimate’ visits in which foragers take nectar without providing pollination services. The data on prevalence of illegitimate visits among hummingbirds, as well as the total proportion of foraging and diet that such visits comprise is broadly lacking. Here, we report the occurrence of nectar larceny in the two currently recognized species of trainbearers and analyze the proportion of plant visits categorized by mode of interaction...

A new balaenopterid species from the Southern North Sea Basin informs about phylogeny and taxonomy of Burtinopsis and Protororqualus (Cetacea, Mysticeti, Balaenopteridae)
Background An extensive radiation can be inferred among balaenopterid mysticetes in the last 10 million years based on a rich fossil record. Many extinct genera and species have been established in the past by the study of fossil rorquals from northern and southern hemispheres. In many cases, the new fossils are used to create new genera. However, in very recent times, new species of known genera have been described that help our understanding of the speciation processes and the biogeography of...

Evaluation of epidemiological lectures using peer instruction: focusing on the importance of ConcepTests
Background In clinical research, the ability to properly analyze data is a necessary skill that cannot be learned simply by listening to lectures. Interactive classes, such as Peer Instruction (PI), are required to help medical students understand the concept of epidemiology for future valid research. In PI lectures, ConcepTests are conducted to confirm and deepen students’ understanding of the lecture material. Although it is important to evaluate PI lectures, there have been no...

Effects of low temperature at stem elongation stage on the development, morphology, and physicochemical properties of wheat starch
The low temperature in spring is a meteorological problem in wheat production because it leads to yield reduction and alteration of wheat quality. In this study, an artificial low-temperature treatment (LTT) at the stem elongation stage was implemented to investigate the starch granule development and physical and chemical properties of wheat starch. Results showed that the agronomic traits of spike, such as spike length, spikelet number per spike, and grain number per spikelet, decreased after LTT....

Global expansion of COVID-19 pandemic is driven by population size and airport connections
The pandemic state of COVID-19 caused by the SARS CoV-2 put the world in quarantine, led to hundreds of thousands of deaths and is causing an unprecedented economic crisis. However, COVID-19 is spreading in different rates at different countries. Here, we tested the effect of three classes of predictors, i.e., socioeconomic, climatic and transport, on the rate of daily increase of COVID-19 on its exponential phase. We found that population size and global connections, represented by countries’ importance...

Larval longevity and competency patterns of Caribbean reef-building corals
The potential for long-distance larval dispersal depends on the longevity of planktonic, free-swimming larvae and their capacity to successfully recruit to reef habitat. We present multi-year laboratory observations of the persistence of planular larvae and settlement competency over time for cohorts derived from the same parental populations of the most important Caribbean reef building coral species, Orbicella faveolata and Acropora spp. Despite variability among years/cohorts, larvae of both species...
