A Exon-52 Deleted Miniature Pig Model of Duchenne Muscular Dystrophy and Evaluation of Exon Skipping.

Duchenne muscular dystrophy (DMD) is a lethal X-linked recessive disorder caused by mutations in the gene and the subsequent lack of dystrophin protein. Recently, phosphorodiamidate morpholino oligomer (PMO)-antisense oligonucleotides (ASOs) targeting exon 51 or 53 to reestablish the reading frame have received regulatory approval as commercially available drugs. However, their applicability and efficacy remain limited to particular patients.

Corpus Callosotomy in 3 Cavalier King Charles Spaniel Dogs with Drug-Resistant Epilepsy.

Corpus callosotomy (CC) is an established palliative surgery for human patients with drug-resistant epilepsy (DRE), especially those with generalized seizures and multiple or unknown epileptogenic focus. However, there are no reports to describe CC in canine patients with epilepsy. Three client-owned Cavalier King Charles Spaniels with DRE are included in this case series.

Comparative morphological study of skeletal muscle weight among the red jungle fowl (Gallus gallus) and various fowl breeds (Gallus domesticus).

We examined the weight distribution of skeletal muscles of the red jungle fowl, then compared these values with those of domesticated populations to determine how muscle distribution has changed by selecting breeding. Sonia, Fayoumi, and Rhode Island Red were selected for comparison from livestock breeds, while Japanese Shamo and Thai fighting cocks were selected from cockfighting groups. Principal component analysis was applied using body size-free data.

Relationships between management factors in dairy production systems and mental health of farm managers in Japan.

To facilitate sustainable dairy farming, it is essential to assess and support the mental health of dairy farm workers, which is affected more than that of workers in other industries, as indicated by the relatively few studies to date. In addition, the limited investigations on mental health in dairy workers minimize the opportunities to suggest practical approaches of improvement of their mental health. Therefore, further data acquisition and analysis is required.

Application of integrative physiological approach to evaluate human physiological responses to the inhalation of essential oils of Japanese citrus fruits iyokan (Citrus iyo) and yuzu (Citrus junos).

This study investigated the effects of essential oil odors from Japanese citrus fruits, iyokan (Citrus iyo) and yuzu (Citrus junos), on human psychology and both the autonomic and central nervous systems. The inhalation of both essential oils significantly increased miosis rate and fingertip temperature and could induce parasympathetic dominance by suppressing sympathetic nerve activity. Oxyhemoglobin concentration in the prefrontal cortex increased after the inhalation of yuzu essential oil and decreased after the inhalation of iyokan essential oil.

Herein, we investigated the distribution and genome structures of mitomycin C-inducible temperate phages in AAB. Transmission electron microscopy analysis revealed phage-like particles in 15 out of a total 177 acetic acid bacterial strains, all of which showed morphology similar to myoviridae-type phage.

Zinc Inhibits Cadherin 1 Expression Induced by 1α,25-Dihydroxyvitamin D in Colon Cancer Cells.

Background: Zinc is a mineral that is essential for biological molecules, such as transcription factors, and is involved in the maintenance of intestinal homeostasis. Vitamin D signaling is mediated by vitamin D receptor (VDR) activated by 1α,25-dihydroxyvitamin D [1,25(OH)D] and is also important in intestinal functions, such as calcium absorption and epithelial barrier maintenance. However, the crosstalk between vitamin D signaling and zinc signaling in intestinal cells remains poorly understood.

Morphological and histochemical characterization of the secretory epithelium in the canine lacrimal gland.

In the present study, the expression of secretory components and vesicular transport proteins in the canine lacrimal gland was examined and morphometric analysis was performed. The secretory epithelium consists of two types of secretory cells with different morphological features. The secretory cells constituting acinar units (type A cells) exhibited higher levels of glycoconjugates, including β-GlcNAc, than the other cell type constituting tubular units (type T cells).

Development and evaluation of a multiplex qPCR assay for rapid diagnostics of emerging sporotrichosis.

Sporothrix schenckii and related species are the agents of human and animal sporotrichosis. Routine diagnoses using classical mycological approaches are unspecific due to overlapping phenotypes. As the frequency and prevalence of sporotrichosis increases worldwide, developing specific, sensitive and cost-effective diagnostic tools is essential to understand the distribution patterns, map-affected areas and promote specific public health strategies to mitigate future outbreaks.

Activation of canine neutrophils by platelet-activating factor.

Neutrophils are essential for innate immunity as the first line of defence. Neutrophils act as phagocytic white blood cells to kill bacteria and other microorganisms. A strong respiratory burst of neutrophils, dependent on reactive oxygen species, is produced during phagocytosis.

Changes in gaseous concentration of alkylpyrazine analogs affect mouse avoidance behavior.

We developed a rapid and accurate method for quantifying gaseous phase odorants using headspace solid-phase microextraction (HS-SPME) in conjunction with GC-MS and used our system to quantify alkylpyrazine analogs in the Y-maze. Rapid extraction of volatile compounds in the vapor phase achieved accurate quantitative analysis of gaseous alkylpyrazine analogs at several locations in the Y-maze. We also used a series of three SPME fibers to quantify changes in the concentration over time.

Caliciviruses induce mRNA of tumor necrosis factor α via their protease activity.

Calicivirus infection in patients and animals is associated with the production of multiple inflammatory cytokines, including tumor necrosis factor α (TNF-α). Here we studied the feline calicivirus (FCV) non-structural proteins and found that the FCV protease was a key factor for TNF-α gene expression in cultured cells. The expression of the TNF-α gene in cells expressing FCV, human norovirus, and rabbit hemorrhagic disease virus protease was compared, revealing that the induction of TNF-α could be a common phenomenon during the infection by the viruses in the Caliciviridae.

Odorant metabolism of the olfactory cleft mucus in idiopathic olfactory impairment patients and healthy volunteers.

Background: It remains unclear whether the metabolic activity of nasal mucus in the olfactory and respiratory areas is different. Moreover, age- and olfaction-related changes may affect metabolism.

Methods: Hexanal, octanal, and 2-methylbutanal were selected for in vitro metabolism analysis and compared between the olfactory cleft and respiratory mucus of participants < 50-year-old with normal olfaction using gas chromatography mass spectrometry.

Cdc42 activates paracellular transport in polarised submandibular gland cells.

Objective: The physiological expression of cell division cycle 42 (cdc42) in major salivary glands, and paracellular transport of fluorescein isothiocyanate-dextran (FITC-dextran) in SMIE cells, which regulate cdc42 expression, was investigated to clarify the involvement of cdc42 in salivary production.

Design: The physiological expression of cdc42 in the rat submandibular gland, parotid gland, sublingual gland, and SMIE cells was detected using SDS-PAGE and western blotting. The paracellular transport of FITC-dextran in transwells was compared in transfected SMIE cells, exhibiting up- or downregulated cdc42 expression.

A new duplex PCR assay for the rapid screening of mating-type idiomorphs of pathogenic Sporothrix species.

Sporothrix schenckii and allied species are thermodimorphic fungi widely distributed in nature which causes human and animal sporotrichosis, the most common subcutaneous mycosis globally. Sporotrichosis is acquired after a traumatic inoculation of soil or plant material contaminated with Sporothrix propagules or through bites and scratches from diseased cats. In Ascomycota, the master regulators of sex are MAT genes that lie in a single mating-type locus, in Sporothrix these are determined by two nonhomologous alleles, MAT1-1 and MAT1-2.
