Ultra-Low Power Analog Folded Neural Network for Cardiovascular Health Monitoring.

Wearable sensors are increasingly used for continuous health monitoring, but their small size limits battery capacity, affecting user experience and monitoring capabilities. To overcome this, we introduce an ultra-low power analog Folded Neural Network (FNN) for physiological signal processing in a batteryless fashion. Our proposed FNN, by serializing computation, provides several benefits over traditional analog implementations, such as lower space, lower power consumption, and lower peak-to-average power ratio.

Development and validation of a universal primer pair for the taxonomic and phylogenetic studies of vertebrates.

Background: Recent studies in the field of molecular identification have described 16S rRNA gene as a highly informative fragment of mitochondrial DNA for species discrimination. This study presents a newly developed universal primer pair yielding an approximately 350 bp fragment of mitochondrial 16S rRNA, variable enough to encompass and identify all vertebrate classes.

Methods And Results: The primers were designed by aligning and analyzing over 1500 16S rRNA sequences downloaded from the NCBI nucleotide database.

Molecular evolution, virology and spatial distribution of HCV genotypes in Pakistan: A meta-analysis.

Methods: To address this, a review was conducted to determine the prevalence of HCV genotypes across various provinces and as a whole in Pakistan.

Cryogenic vacuum valve with actuation times down to 50 ms.

We have conceived, built, and operated a cryogenic vacuum valve with opening and closing times as short as 50 ms that can be used in strong magnetic fields and across a broad range of duty cycles. It is used to seal a cryogenic Penning trap at liquid-helium temperature for long-term storage of highly charged ions in a vacuum better than 10-15 hPa from a room-temperature ion beamline at vacuum conditions around 10-9 hPa. It will significantly improve any experiment where a volume at the most extreme vacuum conditions must be temporarily connected to a less demanding vacuum during repeated experimental cycles.

Vaccine Adjuvants: Selection Criteria, Mechanism of Action Associated with Immune Responses and Future Directions.

The most effective method to minimize the prevalence of infectious diseases is vaccination. Vaccines enhance immunity and provide protection against different kinds of infections. Subunit vaccines are safe and less toxic, but due to their lower immunogenicity, they need adjuvants to boost the immune system.

modulates JAK/STAT pathway and protects flies against C virus infection.

Sterile alpha and HEAT/Armadillo motif-containing protein (SARM) is conserved in evolution and negatively regulates TRIF-dependent Toll signaling in mammals. The SARM protein from and its orthologue Ectoderm-expressed (Ect4) are also involved in immune defense against pathogen infection. However, the functional mechanism of the protective effect remains unclear.

Resistance Patterns of Frequently Applied Antimicrobials and Occurrence of Antibiotic Resistance Genes in Detected in Edwardsiellosis-Infected Tilapia Species of Fish Farms of Punjab in Pakistan.

is one of the most significant fish pathogens, causes edwardsiellosis in a variety of freshwater fish species, and its antibiotic resistance against multiple drugs has made it a health risk worldwide. In this study, we aimed to investigate the antibiotic resistance (ABR) genes of and establish its antibiotic susceptibility. Thus, 540 fish (299 , 138 , and 103 ) were collected randomly from twelve fish farms in three districts of Punjab in Pakistan.

Gold nanoparticles capped with L-glycine, L-cystine, and L-tyrosine: toxicity profiling and antioxidant potential.

Biomolecules-based surface modifications of nanomaterials may yield effective and biocompatible nanoconjugates. This study was designed to evaluate gold nanoconjugates (AuNCs) for their altered antioxidant potential. Gold nanoparticles (AuNPs) and their conjugates gave SPR peaks in the ranges of 512-525 nm, with red or blueshift for different conjugates.

Dual Role of Indoles Derived From Intestinal Microbiota on Human Health.

Endogenous indole and its derivatives (indoles), considered as promising N-substituted heterocyclic compounds, are tryptophan metabolites derived from intestinal microbiota and exhibit a range of biological activities. Recent studies indicate that indoles contribute to maintaining the biological barrier of the human intestine, which exert the anti-inflammatory activities mainly through activating AhR and PXR receptors to affect the immune system's function, significantly improving intestinal health (inflammatory bowel disease, hemorrhagic colitis, colorectal cancer) and further promote human health (diabetes mellitus, central system inflammation, and vascular regulation). However, the revealed toxic influences cannot be ignored.

A 6-point subdivision scheme and its applications for the solution of 2nd order nonlinear singularly perturbed boundary value problems.

In this paper, we first present a 6-point binary interpolating subdivision scheme (BISS) which produces a continuous curve and 4th order of approximation. Then as an application of the scheme, we develop an iterative algorithm for the solution of 2nd order nonlinear singularly per-turbed boundary value problems (NSPBVP). The convergence of an iterative algorithm has also been presented.

CRISPR-CAS Replacing Antiviral Drugs against HIV: An Update.

Various antiretroviral drugs do not kill or cure the human immunodeficiency virus (HIV) but do prevent the replication of the virus. The combination of antiretroviral drugs is known as highly active antiretroviral therapy (HAART). Current drug therapies effectively suppress HIV-1 replication but do not inactivate the provirus that persists in latent reservoirs.
