Remote Heart Rate Prediction in Virtual Reality Head-Mounted Displays Using Machine Learning Techniques.

Head-mounted displays are virtual reality devices that may be equipped with sensors and cameras to measure a patient's heart rate through facial regions. Heart rate is an essential body signal that can be used to remotely monitor users in a variety of situations. There is currently no study that predicts heart rate using only highlighted facial regions; thus, an adaptation is required for beats per minute predictions.

Lost pigs of Angola: Whole genome sequencing reveals unique regions of selection with emphasis on metabolism and feed efficiency.

Angola, in the western coast of Africa, has been through dramatic social events that have led to the near-disappearance of native swine populations, and the recent introduction of European exotic breeds has also contributed to the erosion of this native swine repertoire. In an effort to investigate the genetic basis of native pigs in Angola (ANG) we have generated whole genomes from animals of a remote local pig population in Huambo province, which we have compared with 78 genomes of European and Asian pig breeds as well as European and Asian wild boars that are currently in public domain. Analyses of population structure showed that ANG pigs grouped within the European cluster and were clearly separated from Asian pig breeds.

Responsive Role of Nanomedicine in the Tumor Microenvironment and Cancer Drug Resistance.

Cancer remains a major worldwide health challenge. Current studies emphasize the tumor microenvironment that plays a vital role in tumor proliferation, invasion, metastasis, and drug resistance. The tumor microenvironment (TME) supports the cancer cell to evade conventional treatment such as surgery, radiotherapy, and chemotherapy.

ReNoteWeb - Web platform for the improvement of assembly result and annotation of prokaryotic genomes.

The reduction in the cost of DNA sequencing and the total time to perform this process has resulted in a significant increase in the deposit of biological information in public databases such as the NCBI (National Center for Biotechnology Information). The production of large volumes of data per run has culminated in the need to develop algorithms capable of handling data with this new feature and assisting in analyses such as the assembly and annotation of prokaryotic genomes. Over the years, several pipelines and computational tools have been developed to automate this task and consequently reduce the total time to know the genetic content of a given organism, especially non-model organisms, collaborating with the identification of possible targets with biotechnological applicability.

Transcriptomic analysis reveals the effects of maternal selenium deficiency on placental transport, hormone synthesis, and immune response in mice.

Selenium deficiency has been considered to increase the risk of gestational complications. Our previous work showed that maternal selenium deficiency suppressed proliferation, induced autophagy dysfunction, and apoptosis in the placenta of mice. However, other effects of maternal selenium deficiency on the placenta and the underlying mechanisms remain unclear.

Application of Therapeutic Nanoplatforms as a Potential Candidate for the Treatment of CNS Disorders: Challenges and Possibilities.

Drug delivery to central nervous system (CNS) diseases is one of the most challenging tasks. The innate blood-brain barrier (BBB) and the blood-cerebrospinal fluid (BCSF) barrier create an obstacle to effective systemic drug delivery to the CNS, by limiting the access of drugs to the brain. Nanotechnology-based drug delivery platform offers a potential therapeutic approach for the treatment of neurological disorders.

L.F. (Phyllanthaceae): Ethnopharmacology and Application of Computational Tools in the Annotation of Bioactive Molecules.

is a shrubby species widely distributed in Brazil from the Amazon to the Atlantic Rainforest. Its bark and fruit are used in the Peruvian Amazon for disinfecting abscesses and as a tonic in pregnancy, respectively, and its leaves are used to treat cancer symptoms. From analyses via UHPLC-MS/MS, we sought to determine the chemical profile of the ethanolic extract of leaves by means of putative analyses supported by computational tools and spectral libraries.

The ability to wear heeled footwear following first metatarsophalangeal joint fusion.

Introduction: Fusion remains the gold standard treatment for symptomatic first metatarsophalangeal joint (MTPJ) arthritis. Surgeons have traditionally advised female patients during the consenting process that they would have limitations or be unable to wear heeled footwear following first MTPJ fusion due to the loss of dorsiflexion at the first MTPJ. Anecdotally, surgeons have found that some patients were still able to continue wearing heeled footwear post fusion surgery.

Patients With Un-Displaced Or Displaced Intra Capsular Proximal Femur Fractures Do Not Represent A Different Patient Group And Have Similar Short And Long Term Mortality.

Background: Proximal femur fractures in geriatric patients are associated with substantial mortality. Management of intracapsular proximal femur fractures has been based on age, displacement, cognition, and pre-injury mobility. However, over the last decade, there has been a tendency to offer arthroplasty rather than internal fixation for these patients irrespective of displacement, to allow early mobilisation and negate the higher rate of reoperation due to failed internal fixation.
