Article Synopsis
  • This study looked at women with bladder cancer who had surgery to remove their bladder and other reproductive organs to see how many still had problems with their reproductive organs.
  • Out of 417 women, some had their uterus and vaginal wall saved, but about 9% showed signs of cancer in their reproductive areas.
  • The researchers concluded that doctors need to think carefully about whether to save these organs during surgery because there's a risk that cancer could still affect them.

Article Synopsis
  • - Patients with ALK-positive non-small cell lung cancer often benefit from ALK tyrosine kinase inhibitors, but resistance mutations commonly lead to cancer recurrence, highlighting the need for early detection methods.
  • - This study aimed to develop a highly sensitive and cost-effective technique using oligoribonucleotide interference-PCR (ORNi-PCR) combined with droplet digital PCR (ddPCR) to detect common ALK-TKI resistance mutations (G1202R and L1196M) in cell-free DNA from patients.
  • - The results showed that ORNi-PCR successfully identified as few as 1-10 copies of the resistance mutations in model samples and patient samples, outpacing conventional methods, which could enhance early detection of resistant NSCLC.*

A regulatory mechanism for SLC family transporters, critical transporters for sodium and glucose reabsorptions in renal tubule, is incompletely understood. Here, we report an important regulation of SLC family transporter by SETD2, a chromatin remodeling gene whose alterations have been found in a subset of kidney cancers. Kidney-specific inactivation of Setd2 resulted in hypovolemia with excessive urine excretion in mouse and interestingly, RNA-sequencing analysis of Setd2-deficient murine kidney exhibited decreased expressions of SLC family transporters, critical transporters for sodium and glucose reabsorptions in renal tubule.

Article Synopsis
  • The sympathetic nervous system reacts to psychological stress by raising blood pressure, a condition that can persist even after the stress is gone, potentially contributing to hypertension.
  • Researchers investigated how astrocytes, a type of brain cell, influence this ongoing rise in blood pressure using arundic acid, an inhibitor of astrocytes.
  • The study found that arundic acid reduced the blood pressure increase caused by stress in rats, indicating that both neurons and astrocytes are important in understanding stress-related hypertension.

Article Synopsis
  • Seed development is crucial for sexual reproductive plants, and specific alleles at certain loci are necessary for proper seed development.
  • The study focused on fine mapping of a gene related to seed development, narrowing it down to a 333kb region on chromosome 6 and indicating a shared common abortive allele among specific accessions.
  • Further linkage analysis identified a candidate gene on chromosome 4, revealing five potential protein-coding genes that could be linked to seed development, suggesting their orthologs may also play a role in related species.

Vacuum residue (VR) was copyrolysed with polyethylene (PE) or polystyrene (PS) in a batch reactor to investigate the corresponding synergistic pyrolytic interactions. The synergistic interactions between VR and plastic pyrolysates enhanced liquid and gas production while reducing coke formation, as compared with VR-only and plastic-only pyrolysis. The pyrolysis of 9:1 w/w VR: PE (PE with M = 3 MDa) and 9:1 w/w VR/PS (PS with M ≈ 350 kDa) mixtures produced oil in yields of 28.

Article Synopsis
  • SBRT (Stereotactic body radiation therapy) is shown to be less invasive and more cost-effective compared to surgery for treating operable stage I non-small cell lung cancer (NSCLC) in Japan.
  • In a study, SBRT resulted in lower treatment costs by about $4,444 and improved quality-adjusted life years (QALYs) by 0.131 compared to surgery, with an overall survival rate of 78.2% versus 74.8%.
  • The findings suggest SBRT is a preferred treatment option, but further large-scale studies are necessary to confirm these results.

December 2024

Department of Health and Nutritional Sciences, Faculty of Health and Medical Sciences, Aichi Shukutoku University, Nagakute-city, Aichi, Japan.

In Brief: Social and reproductive behaviors in mammals are regulated by pheromones. This study shows the possibility that male extraorbital lacrimal gland-derived pheromones are involved in reproductive efficiency in rats.

Abstract: In rodents, male-derived pheromones play fundamental roles in reproduction.

Article Synopsis
  • Researchers created and validated a risk model for high-risk metastatic hormone-sensitive prostate cancer (mHSPC) patients treated with abiraterone acetate (ABI) to better predict patient outcomes.
  • The study involved 233 patients from three academic centers and validated the model on a separate group of 282 patients, analyzing factors that influence progression-free survival (PFS2) and overall survival (OS).
  • Key findings showed that the model effectively categorized patients into risk groups, with poor-risk patients having significantly lower median PFS2 and OS compared to favorable and intermediate groups, aiding in treatment planning.

Introduction Short-term levodopa-carbidopa intestinal gel (LCIG) treatment using nasojejunal (NJ) tubes (NJ-LCIG test) is recommended for patients with advanced Parkinson's disease to ensure compatibility with this treatment system prior to permanent percutaneous endoscopic gastrojejunostomy. However, there have been no studies on NJ tube insertion by neurologists or on possible differences in treatment efficacy based on the NJ tube insertion method or tube tip position. We therefore investigated the effects of LCIG with NJ tube placement performed by a neurologist.

  • - Gastric cancer is prevalent in East Asia, and a study analyzed Japanese health insurance data from 2014 to 2021 to assess trends in surgeries for this condition.
  • - The study found that the total number of gastric resections peaked in 2015 but dropped during the COVID-19 pandemic, with a growing preference for endoscopic procedures over total gastrectomies.
  • - Notably, in 2021, most patients undergoing resections were older men, and there were significant regional differences in the types of surgeries performed, highlighting the need for standardized treatment approaches.

This study explores the challenge of differentiating autism spectrum (AS) from non-AS conditions in adolescents and adults, particularly considering the heterogeneity of AS and the limitations ofssss diagnostic tools like the ADOS-2. In response, we advocate a multidimensional approach and highlight lexicogrammatical analysis as a key component to improve diagnostic accuracy. From a corpus of spoken language we developed, interviews and story-recounting texts were extracted for 64 individuals diagnosed with AS and 71 non-AS individuals, all aged 14 and above.

Article Synopsis
  • Intracellular bacteria cause severe pneumonia in foals, and T-helper (Th) 1 cells are crucial for the immune response against this infection.
  • A study over four years categorized infected foals into surviving and non-surviving groups, analyzing their immune responses, particularly focusing on immunoglobulin G (IgG) subclasses.
  • Results showed that non-surviving foals had significantly higher IgGa, IgGb, and IgG(T) levels, indicating that an imbalance in these IgG subclasses may worsen the infection and relates to their immune status.

September 2024

Graduate School of Science and Technology, Hirosaki University, Hirosaki, Aomori, Japan.

In silico design of artificial riboswitches is a challenging and intriguing task. Since experimental approaches such as in vitro selection are time-consuming processes, computational tools that guide riboswitch design are desirable to accelerate the design process. In this chapter, we describe the usage of the MODENA web server to design ON riboswitches on the basis of a multi-objective genetic algorithm and RNA secondary structure prediction.
