Early and late place cells during postnatal development of the hippocampus.

A proportion of hippocampal CA1 neurons function as place cells from the onset of navigation, which are referred to as early place cells. It is not clear whether this subset of neurons is predisposed to become place cells during early stages, or if all neurons have this potential. Here, we longitudinally imaged the activity of CA1 neurons in developing male rats during navigation with both one-photon and two-photon microscopy.

Height prediction of individuals with osteogenesis imperfecta by machine learning.

Background: Osteogenesis imperfecta (OI) is a genetic disorder characterized by low bone mass, bone fragility and short stature. There is a significant gap in knowledge regarding the growth patterns across different types of OI, and the prediction of height in individuals with OI was not adequately addressed. In this study, we described the growth patterns and predicted the height of individuals with OI employing multiple machine learning (ML) models.

Bacillus phage phi18-2 is a novel temperate virus with an unintegrated genome present in the cytoplasm of lysogenic cells as a linear phage-plasmid.

Bacillus subtilis is a Gram-positive bacterium that is widely used in fermentation and in the pharmaceutical industry. Phage contamination occasionally occurs in various fermentation processes and causes significant economic loss. Here, we report the isolation and characterization of a temperate B.

Psychrophilic phage phiGM22-3 efficiently controls Pseudomonas fluorescens contamination in cold-stored milk.

Pseudomonas fluorescens is a common spoilage causing microbe found in milk. Antibiotic preservatives may cause emergence of multidrug resistance, posing food safety related risks to public health. Phage treatment may be used as an alternative to antibiotics in controlling P.

Alternating current stimulation promotes neurite outgrowth and plasticity in neurons through activation of the PI3K/AKT signaling pathway.

As a commonly used physical intervention, electrical stimulation (ES) has been demonstrated to be effective in the treatment of central nervous system disorders. Currently, researchers are studying the effects of electrical stimulation on individual neurons and neural networks, which are dependent on factors such as stimulation intensity, duration, location, and neuronal properties. However, the exact mechanism of action of electrical stimulation remains unclear.

The patient-related factors in revision procedures on tibia of patients with osteogenesis imperfecta treated with the Peter-Williams nail.

Objective: To investigate the patient-related factors that affect the revision rate for the tibia in patients with osteogenesis imperfecta treated with the Peter-Williams nail, and to explore the relationship between the risk factors and complications postsurgery.

Methods: We retrospectively analysed the data of 211 patients (93 females (44.08%) and 118 males (55.

Which is the best femoral implant in children with osteogenesis imperfecta? a retrospective cohort study of 783 procedures.

Background: Osteogenesis imperfecta (OI) is a hereditary genetic disorder characterized by bone fragility and extremity deformities. The surgical management for long-bone fractures and deformities in OI remains a challenge. We aimed to compare clinical outcomes after femoral surgery splinted with the telescopic rod, the plate and screws, the elastic nail and the non-elongating rod in setting of OI.

Variants of a putative baseplate wedge protein extend the host range of Pseudomonas phage K8.

Background: Narrow host range is a major limitation for phage applications, but phages can evolve expanded host range through adaptations in the receptor-binding proteins.

Results: Here, we report that Pseudomonas phage K8 can evolve broader host range and higher killing efficiency at the cost of virion stability. Phage K8 host range mutant K8-T239A carries a mutant version of the putative baseplate wedge protein GP075, termed GP075m.

Bacillus subtilis phage phi18: genomic analysis and receptor identification.

Bacillus subtilis strains play a pivotal role in the fermentation industry. B. subtilis phages can cause severe damage by infecting bacterial cells used in industrial fermentation processes.

Phage phiZ98: A novel tri-segmented dsRNA cystovirus for controlling Pseudomonas strains with defective lipopolysaccharides in foods.

Many Pseudomonas phages recognize lipopolysaccharides (LPS) as the receptor for infection. LPS defective mutants are often recovered from phage treatments, possibly causing the failure of phage applications. In this work, we isolated a lytic Pseudomonas phage, phiZ98, that can specifically lyse LPS defective strains of the genus Pseudomonas.

Escherichia coli phage phi2013: genomic analysis and receptor identification.

Escherichia coli is an important foodborne pathogen that can cause severe human disease. Here, we report the isolation and characterization of the lytic virus phi2013, which is specific for Escherichia coli laboratory strains. Transmission electron microscopy showed that phage phi2013 has an icosahedral head and a long, fragile, noncontractile tail, exhibiting the typical form of a siphovirus.

Sparse imaging and reconstruction tomography for high-speed high-resolution whole-brain imaging.

Understanding brain functions requires detailed knowledge of long-range connectivity through which different areas communicate. A key step toward illuminating the long-range structures is to image the whole brain at synaptic resolution to trace axonal arbors of individual neurons to their termini. However, high-resolution brain-wide imaging requires continuous imaging for many days to sample over 10 trillion voxels, even in the mouse brain.

Prolonged chronic social defeat stress promotes less resilience and higher uniformity in depression-like behaviors in adult male mice.

Chronic social defeat stress (CSDS) is widely applied to study of depression in rodents. 10-day CSDS was a most commonly employed paradigm but with high resilience ratio (∼30%), producing potential variation in depression-like behavioral symptoms. Whether prolonged period (21 days) of CSDS would promote less resilience and reduce behavioral variability remains unknown.

The Effect of Streptococcus salivarius K12 on Halitosis: a Double-Blind, Randomized, Placebo-Controlled Trial.

This study was to evaluate the effect of Streptococcus salivarius K12 on tongue coating-associated halitosis. Twenty-eight subjects having tongue coating-associated halitosis were randomly divided into either a test or control group. For each of the 30 days, the test subjects sucked S.

A putative LysR-type transcriptional regulator inhibits biofilm synthesis in .

Biofilm formation is an important virulence factor which is controlled by complex regulatory circuits in . In this work, a biofilm hyper-producing strain, P2-7, was selected from a collection of transposon insertion mutants in which the gene was disrupted. was predicted as a putative LysR-type regulator.

Regulatory protein SrpA controls phage infection and core cellular processes in Pseudomonas aeruginosa.

Our understanding of the molecular mechanisms behind bacteria-phage interactions remains limited. Here we report that a small protein, SrpA, controls core cellular processes in response to phage infection and environmental signals in Pseudomonas aeruginosa. We show that SrpA is essential for efficient genome replication of phage K5, and controls transcription by binding to a palindromic sequence upstream of the phage RNA polymerase gene.

[A molecular epidemiological study of KI polyomavirus and WU polyomavirus in children with acute respiratory infection in Tianjin, China].

Objective: To investigate the relationship of KI polyomavirus (KIPyV) and WU polyomavirus (WUPyV) with acute respiratory infection in children in Tianjin, China.

Methods: A total of 3 730 nasopharyngeal secretions were collected from hospitalized children with acute respiratory infection in Tianjin Children's Hospital from January 2011 to December 2013. Viral nucleic acid was extracted, and virus infection (KIPyV and WUPyV) was determined by PCR.
