Full-Length Infectious Clones of Two New Isolates of Tomato Mosaic Virus Induce Distinct Symptoms Associated with Two Differential Amino Acid Residues in 128-kDa Protein.

In 2017, two new tomato mosaic virus (ToMV) isolates were collected from greenhouses in Buyeo, Chungcheongnam-do, South Korea. Full-length cDNAs of the new ToMV isolates were cloned into dual cauliflower mosaic virus 35S and T7 promoter-driven vectors, sequenced and their pathogenicities investigated. The nucleotide sequences of isolates GW1 (MH507165) and GW2 (MH507166) were 99% identical, resulting in only two amino acid differences in nonconserved region II and the helicase domain, Ile668Thr and Val834Ile.

Allopurinol Protects against Ischemia/Reperfusion-Induced Injury in Rat Urinary Bladders.

Bladder ischemia-reperfusion (I/R) injury results in the generation of reactive oxygen species (ROS) and markedly elevates the risk of lower urinary tract symptoms (LUTS). Allopurinol is an inhibitor of xanthine oxidase (XO) and thus can serve as an antioxidant that reduces oxidative stress. Here, a rat model was used to assess the ability of allopurinol treatment to ameliorate the deleterious effects of urinary bladder I/R injury.

Protective effect of N-acetylcysteine against ischemia/reperfusion injury in rat urinary bladders.

Ischemia/reperfusion (I/R) injury represents an important cause of bladder contractile dysfunction. One of the major causes leading to this dysfunction is thought to be reactive oxygen species formation. In this study, we investigated the potential benefit of N-acetylcysteine (NAC), a potent antioxidant that neutralizes free radicals, in a rat model of urinary bladder injury.

Neuregulin 1 up-regulates the expression of nicotinic acetylcholine receptors through the ErbB2/ErbB3-PI3K-MAPK signaling cascade in adult autonomic ganglion neurons.

We investigated effects of Neuregulin 1 (NRG1) on the expression of nicotinic acetylcholine receptor (nAChR) in major pelvic ganglion (MPG) from adult rat. MPG neurons were found to express transcripts for type I and III NRG1s as well as α and β-type epidermal growth factor (EGF)-like domains. Of the four ErbB receptor isoforms, ErbB1, ErbB2, and ErbB3 were expressed in MPG neurons.

Changes in Urinary Symptoms and Tolerance due to Long-term Ureteral Double-J Stenting.

Purpose: Most studies have reported the effects of short-term double-J ureteral stenting on patient symptoms. We reviewed the changes in symptoms and the factors associated with tolerance due to long-term stenting.

Materials And Methods: We investigated 20 patients (mean age±SD, 58.

Detrusor and blood pressure responses to dorsal penile nerve stimulation during hyperreflexic contraction of the bladder in patients with cervical cord injury.

Objective: To investigate the immediate effect of dorsal penile nerve (DPN) stimulation on detrusor pressure (P(det)) and blood pressure during hyperreflexic contractions of the bladder in patients with cervical spinal cord injury (SCI).

Design: Blood pressure and P(det) monitoring during cystometry with and without DPN stimulation.

Setting: Urodynamic laboratory in a university hospital in Korea.
