Tuberculosis (TB) manifests in various forms, including extrapulmonary tuberculosis (EPTB), which poses diagnostic dilemmas due to its wide-ranging clinical presentations. When TB affects the bones of the hands and feet, it can present a diagnostic labyrinth for clinicians. In such cases, the differential diagnosis may include Jungling's bone disease, adding complexity to the diagnostic process.

Objective: The objective of this study is to compare the effect of the location of recombinant human bone morphogenetic protein 2 (rhBMP-2) from the native bone and the periosteum for vertical alveolar bone augmentation.

Materials And Methods: Mandibular, chronic, standardized, bilateral, and vertical defects in 12 beagle dogs were evaluated using four modalities: a xenograft alone (XENO; n = 6); rhBMP-2 alone (BMP; n = 6); a technique with rhBMP-2 close to the host bone covered by xenograft (SAN; n = 6); and a technique with rhBMP-2 close to the flap on top of the xenograft (LAS; n = 6). After 8 weeks, a series of in vivo inspections, fluorescence microscopy, histologic and histomorphometric evaluations, and micro-CT analyses.

Department of Otolaryngology - Head and Neck Surgery, Brooke Army Medical Center, JBSA Fort Sam Houston, TX, USA; United States Army Institute of Surgical Research, JBSA Fort Sam Houston, TX, USA; Department of Otolaryngology - Head and Neck Surgery, University of Cincinnati, Cincinnati, OH, USA.

Article Synopsis
  • Oral commissure stenosis and lower eyelid ectropion from burns are difficult to treat due to a lack of preclinical models; this study describes a method for inducing controlled burns in swine to aid future research.
  • The experiment involved inducing burns of various durations (10 to 30 seconds) on swine and observing changes over time using techniques like laser speckle imaging for assessing tissue health and healing.
  • Results indicated that longer burn times led to more severe tissue damage and inflammation, but no significant functional impairments were noted, suggesting the need for further exploration of treatments with this new burn model.

Article Synopsis
  • - Human threadworm is a globally distributed parasite affecting over 600 million people, with serious implications for immunosuppressed individuals, yet its prevalence among Fijian migrants in the UK is largely unknown.
  • - A study involving 250 Fijian migrants in the UK revealed a significant rate of gastrointestinal parasites (GIPs), with 35.1% testing positive for threadworm and 6.8% for hookworms, based on comprehensive diagnostic methods.
  • - Findings emphasized the need for specialized parasitological testing, particularly multiplex real-time PCR (rtPCR), which proved more effective than traditional microscopy in diagnosing infections among chronic cases in this population.

Objectives: The effective control of dental plaque is crucial for oral health, given that pathogenic bacteria in plaque are the primary cause of dental caries. Current antimicrobial agents, although effective, disrupt the oral microbiome and lead to oral dysbiosis, hindering efforts to curb dental caries. Novel antimicrobial peptides offer a promising solution due to their selective bactericidal activity against cariogenic bacteria.

Article Synopsis
  • Travel to resource-limited areas can increase the risk of infections from multi-drug resistant bacteria like ESBL-PE and CRE, which lead to serious health issues.
  • A study examined the prevalence of these bacteria in British service personnel by analyzing 239 fecal samples and discovered a 16.7% presence of ESBL-PE, but no CRE cases were found.
  • While the rate of ESBL-PE in service personnel is similar to that in civilian populations in England, different genetic variations of the bacteria were observed, highlighting the need for ongoing monitoring to track infection risks.

Atomic vacancies of molybdenum disulfide nanoparticles stimulate mitochondrial biogenesis.

Nat Commun

September 2024

Department of Biomedical Engineering, College of Engineering, Texas A&M University, College Station, TX, USA.

Diminished mitochondrial function underlies many rare inborn errors of energy metabolism and contributes to more common age-associated metabolic and neurodegenerative disorders. Thus, boosting mitochondrial biogenesis has been proposed as a potential therapeutic approach for these diseases; however, currently we have a limited arsenal of compounds that can stimulate mitochondrial function. In this study, we designed molybdenum disulfide (MoS) nanoflowers with predefined atomic vacancies that are fabricated by self-assembly of individual two-dimensional MoS nanosheets.
