A 59 year old male presented with a 4 month history of lower urinary tract symptoms. Exhaustive urological investigations revealed papillary tumors and carcinoma in situ extending from the prostatic urethra, throughout the bladder, up both ureters and into the renal pelves. Tumors were resected where possible and then bacillus Calmette-Guèrin (BCG) and mitomycin C (MMC) were infused sequentially through bilateral nephrostomy tubes for a total of six BCG and three MMC instillations. Follow up 1 month post treatment demonstrated a complete response which persisted for 2 years. Then there appeared a solitary papillomatous recurrence in the bladder which was successfully resected. Side effects were the occasional fever and BCG induced granulomatous prostatitis which slowly resolved. In conclusion, sequential BCG/MMC instillations were effective treatment for widespread panurothelial carcinomatosis.

Treatment options for recurrent high-risk non-muscle-invasive bladder cancer (HR NMIBC) and muscle-invasive bladder cancer (MIBC) are limited, highlighting a need for clinically effective, accessible, and better-tolerated alternatives. In this review we examine the clinical development program of TAR-200, a novel targeted releasing system designed to provide sustained intravesical delivery of gemcitabine to address the needs of patients with NMIBC and of those with MIBC. We describe the concept and design of TAR-200 and the clinical development of this gemcitabine intravesical system in the SunRISe portfolio of studies.

Background: Candida albicans is the primary cause of vulvovaginal candidiasis, a worldwide health concern for women. The use of supplemental methods, such as antimicrobial photodynamic therapy (aPDT) and probiotics, was promoted by the ineffectiveness of the existing antifungal drugs.
Methods: This study examines the combined effects of probiotics (Bacillus and Enterococcus isolated from the fermented pickles) and PDT (using red laser (655 nm, 18 J/cm) as a light source and methylene blue dye (30 mg/mL) as a photosensitizer) on the in vitro virulence activity of C.

Degumming, a process of removing gummy substances surrounding fiber, plays a crucial role in preparing plant fibers. This study clearly clarified that the multiple degumming enzymes by Bacillus subtilis XW-18 acted as a decisive factor for driving bio-degumming process of raw pineapple leaves. Firstly, PCR analysis verified that B.

Application of herbicide-degrading bacteria is an effective strategy to remove herbicide in soil. However, the ability of bacteria to degrade a herbicide is often severely limited in the presence of other pesticide. In this study, the atrazine-degrading strain Klebsiella varicola FH-1 and acetochlor-degrading strain Bacillus Aryabhatti LY-4 were used as parent strains to construct the recombinant RH-92 strain through protoplast fusion technology.

Bacterial blight of pomegranate caused by Xanthomonas axonopodis pv. punicae poses significant challenges to sustainable cultivation, necessitating eco-friendly management strategies, and this study explores the role of the phylloplane microbiome in disease suppression through metabarcoding, traditional microbiology, and antibacterial screening of microbial candidates. Here, we mapped the phylloplane microbiome of pomegranate cultivar 'Bhagwa' during bacterial blight development using metabarcoding sequencing (2443,834 reads), traditional microbiological methods (nutrient-rich and minimal media), and scanning electron microscopy.
