Although it is well known that the morphology of Gram-negative rods changes on exposure to antibiotics, the morphology of antibiotic-resistant bacteria in the absence of antibiotics has not been widely investigated. Here, we studied the morphologies of 10 antibiotic-resistant strains of and used bioinformatics tools to classify the resistant cells under light microscopy in the absence of antibiotics. The antibiotic-resistant strains showed differences in morphology from the sensitive parental strain, and the differences were most prominent in the quinolone-and β-lactam-resistant bacteria.

Article Synopsis
  • PARP inhibitors have improved outcomes for ovarian cancer patients, but the best approach for those who relapse during maintenance therapy is unclear.
  • A study examined the effects of platinum-based chemotherapy following PARP-i treatment in recurrent ovarian cancer patients, finding that the addition of bevacizumab significantly improved progression-free survival (PFS).
  • Among 66 patients evaluated, the median PFS for chemotherapy alone was 3.1 months compared to 8.9 months when combined with bevacizumab, suggesting that this combination therapy could be more beneficial for patients.

Sol-gel transitions of polymers are pivotal phenomena in material science, yet the critical phenomenon of structure during gelation has remained unclear. Here, we investigated the sol-gel transition of a fluorous polymer, poly(vinylidene fluoride--hexafluoropropylene), in a blend of two ionic liquids. This system features a quite high amount of cross-linker and binding sites with ion-dipole interactions between the cation and C-F dipoles, thereby facilitating easy exchange of the cross-links.

Article Synopsis
  • The widespread use of antibiotics has led to the emergence of drug-resistant bacteria, requiring new detection methods beyond traditional growth-based approaches.
  • This study focuses on enoxacin-resistant bacteria, using transmission electron microscopy (TEM) images to identify morphological changes without antibiotics.
  • A convolutional neural network (CNN) achieved a high classification accuracy of 0.94, successfully distinguishing between enoxacin-sensitive and resistant strains while highlighting four key genes associated with resistance features.

Benign metastasizing leiomyoma (BML) is a rare disease that is characterized by well-differentiated smooth muscle tumors occurring extrauterine site in women with a history of uterine leiomyoma. The lung is the most common metastatic site for BML. A 48-year-old woman, who had histories of laparoscopic myomectomy and transabdominal total hysterectomy, visited an orthopedics complaining of a mass in her left thigh and difficulty in walking.

A 60-year-old man presented with upper gastrointestinal bleeding. We diagnosed double gastric cancer (adenocarcinoma and adenosquamous carcinoma) based on an endoscopic examination. Due to uncontrollable bleeding, total gastrectomy was performed after 4 courses of chemotherapy with S-1+cisplatin.

We report a case of a 35-year-old patient with acute pancreatitis after administration of ceftriaxone. She was given ceftriaxone (2g/day) for 9 days because of diverticulitis of the colon. She was admitted to our hospital again because of epigastralgia 12 days after the first administration of ceftriaxone.
