There are scant studies of associations between the pubertal status at neutering and subsequent health outcomes of female dogs. This study examined health data for Labrador and Golden Retriever crossbreed bitches neutered by ovariohysterectomy either before (PrePN, = 155) or after (PostPN, = 151) puberty using a prospective study design. Data were extracted from an electronic database containing detailed health records for all bitches.

O-Fucosylation plays crucial roles in various essential biological events. Alongside the well-established O-fucosylation of epidermal growth factor-like repeats by protein O-fucosyltransferase 1 (POFUT1) and thrombospondin type 1 repeats by POFUT2, we recently identified a type of O-fucosylation on the elastin microfibril interface (EMI) domain of Multimerin-1 (MMRN1). Here, using AlphaFold2 screens, co-immunoprecipitation, enzymatic assays combined with mass spectrometric analysis and CRISPR-Cas9 knockouts, we demonstrate that FUT10 and FUT11, originally annotated in UniProt as α1,3-fucosyltransferases, are actually POFUTs responsible for modifying EMI domains; thus, we renamed them as POFUT3 and POFUT4, respectively.

Multi-drug-resistant Mycobacterium tuberculosis is an escalating global health problem, and a strong pipeline of novel compounds is needed to combat rising antimicrobial resistance. Ecumicin is a novel analogue of the natural antimycobacterial cyclic peptide ecumicin, with selective activity against Mycobacterium species. The activity of ecumicin∗ was compared to that of frontline tuberculosis therapies under in vitro conditions representative of niches where M.

Background: Minimally invasive parathyroidectomy (MIP) in patients with a parathyroid adenoma (PA) requires imaging modalities for precise localization. Parathyroid hormone assay on ultrasound-guided fine-needle aspiration washout, or PTH washout, can be used for this purpose. It is unclear whether PTH washout complements traditional PA localization techniques such as a sestamibi (MIBI) scan or diminishes its need.

Video consultations have seen increasing use in nephrology since the COVID-19 pandemic with an aim to address constraints in F2F outpatient capacity and also patients' concerns around risks of infection when attending healthcare facilities. Nephrologists have learned through experience to use video consultations for providing routine follow up and also for triage of unwell patients. Advantages of video consultations include convenience, cost savings through avoiding clinic overheads, and reducing the carbon footprint of care.

The rufomycins are a family of nonribosomal cyclic peptides isolated from the deep sea-dwelling Herein, we describe the total synthesis of six congeners in the rufomycin family. Synthesis was achieved through a modular solid-phase strategy, incorporating synthetic nonproteinogenic amino acids: l-2-amino-4-hexenoic acid, prenyl-l-tryptophan (and related ()-epoxide), and -methyl-δ-hydroxy-l-leucine. Following macrolactamization, these peptides were further diversified through late-stage oxidation and secondary cyclization to furnish a library of six synthetic natural products.

Article Synopsis
  • Neurosarcoidosis can be difficult to diagnose, especially when there are no other systemic symptoms of sarcoidosis, and it often shows varying clinical presentations.
  • Most cases involve issues like cranial neuropathies or meningitis, making isolated spinal cord involvement rare.
  • This case study discusses a 64-year-old woman with a unique form of neurosarcoidosis presenting as myelopathy due to extra-dural nodules, with pathology confirming the diagnosis and no other neurological or systemic symptoms.

Chemokines are small proteins involved in recruiting leukocytes to sites of inflammation via interactions with specific cell surface receptors. CCL22 is a chemokine known to play a critical role in inflammatory diseases such as atopic dermatitis and asthma; inhibition of this chemokine therefore represents an attractive therapeutic strategy. Herein, we describe the discovery of cyclic d-sulfopeptide inhibitors of CCL22 identified through mirror-image mRNA display with genetic reprogramming.

Article Synopsis
  • Patchy data on litter decomposition in wetlands limits understanding of carbon storage, prompting a global study involving over 180 wetlands across multiple countries and climates.
  • The study found that freshwater wetlands and tidal marshes had more organic matter remaining after decay, indicating better potential for carbon preservation in these areas.
  • Elevated temperatures positively affect the decomposition of resistant organic matter, with projections suggesting an increase in decay rates by 2050; however, the impact varies by ecosystem type and highlights the need to recognize both local and global factors influencing carbon storage.

Background: While ultrasound-guided fine-needle aspiration cell block (FNACB) is a cost-effective, expeditious, and reliable procedure used routinely in the initial evaluation of head and neck masses, it has limited efficacy in diagnosing lymphoproliferative disorders such as non-Hodgkin lymphoma (NHL). Flow cytometry performed on an fine-needle aspiration (FNA) sample [ultrasound-guided fine-needle aspirate flow cytometry or flow cytometry performed on an FNA sample (FNAFC)], has been shown to be a valuable adjunct to FNACB in the diagnosis of lymphoproliferative disorders of the spleen, kidney, and thyroid. The objective of this study was to appraise FNAFC's utility as an ancillary tool to detect NHL arising in the head and neck region in adult patients.

  • Molecular testing of thyroid nodules helps identify genetic changes that can indicate the risk of cancer aggressiveness and behavior.
  • The study looked at patients from 2017 to 2024, focusing on those with specific mutations and analyzing their association with aggressive thyroid cancer types.
  • Results showed that patients with both TEL mutations and concurrent alterations were more likely to have high-risk features and aggressive cancer forms, while TEL mutations alone showed a tendency for less aggressive behavior.

Background: Oncocytic thyroid carcinoma (OTC) was previously considered a variant of follicular thyroid carcinoma (FTC) but has recently been reclassified as a separate form of thyroid cancer. This study aimed to demonstrate that FTC and OTC are fundamentally distinct entities that can potentially be differentiated preoperatively through cytology and/or molecular testing.

Methods: A retrospective chart review of patients diagnosed with FTC and OTC operated upon at two university health centers from January 2016 to September 2023 (n = 3219) was conducted.

Background: Effects of neutering on bitch health have been reported, and are suggested to relate to bitch age at the time of neutering for some diseases. However, variation between published studies in terms of study populations and methodologies makes comparison and consolidation of the evidence difficult.

Objective: A scoping review was designed to systematically search the available literature to identify and chart the evidence on the effect of neutering timing in relation to puberty on five health outcomes: atopy, developmental orthopaedic disease (DOD), neoplasia, obesity and urogenital disease.

Background: The perinatal transition's impact on systemic right ventricle (SRV) cardiac hemodynamics is not fully understood. Standard clinical image analysis tools fall short of capturing comprehensive diastolic and systolic measures of these hemodynamics.

Objectives: Compare standard and novel hemodynamic echocardiogram (echo) parameters to quantify perinatal changes in SRV and healthy controls.

Introduction: This study investigates the intersection of ballistic injuries, geography, and Area Deprivation Index (ADI). We hypothesized that both ADI and geography are correlated with incidence of upper extremity ballistic injuries. Further, we characterize and compare 2 distinct upper extremity gunshot injury populations presenting to our institution: those sustaining violent ballistic injuries and those who suffer an accidental, self-inflicted injury.
