Improvement in Survival in Patients With Advanced Non-small Cell Lung Cancer.

Background/aim: New treatment agents for advanced non-small cell lung carcinoma (NSCLC) have improved overall survival (OS) in the last 20 years. Nevertheless, treatment strategies for patients with NSCLC and pulmonary fibrosis have not yet been established. This study aimed to evaluate OS improvement in patients with stage IV NSCLC based on the underlying pulmonary diseases.

Probe Capture Enrichment Sequencing of amoA Genes Improves the Detection of Diverse Ammonia-Oxidising Archaeal and Bacterial Populations.

The ammonia monooxygenase subunit A (amoA) gene has been used to investigate the phylogenetic diversity, spatial distribution and activity of ammonia-oxidising archaeal (AOA) and bacterial (AOB), which contribute significantly to the nitrogen cycle in various ecosystems. Amplicon sequencing of amoA is a widely used method; however, it produces inaccurate results owing to the lack of a 'universal' primer set. Moreover, currently available primer sets suffer from amplification biases, which can lead to severe misinterpretation.

Phase II Trial of Pathology-based Tripartite Treatment Stratification for Patients with CNS Germ Cell Tumors: A Long-term Follow-up Study.

Background: A previous Phase II clinical trial, conducted from 1995 to 2003, evaluated CNS germ cell tumors (GCTs) using a three-group treatment stratification based on histopathology. The primary objective of the study was to assess the long-term efficacy of standardized treatment regimens, while the secondary objective focused on identifying associated long-term complications.

Methods: Total 228 patients were classified into three groups for treatment: germinoma (n=161), intermediate prognosis (n=38), and poor prognosis (n=28), excluding one mature teratoma case.

Generating Synthetic MR Spectroscopic Imaging Data with Generative Adversarial Networks to Train Machine Learning Models.

Purpose: To develop a new method to generate synthetic MR spectroscopic imaging (MRSI) data for training machine learning models.

Methods: This study targeted routine MRI examination protocols with single voxel spectroscopy (SVS). A novel model derived from pix2pix generative adversarial networks was proposed to generate synthetic MRSI data using MRI and SVS data as inputs.

Inhibition of BMP signaling pathway induced senescence and calcification in anaplastic meningioma.

Purpose: Meningiomas are the most common type of brain tumors and are generally benign, but malignant atypical meningiomas and anaplastic meningiomas frequently recur with poor prognosis. The metabolism of meningiomas is little known, so few effective treatment options other than surgery and radiation are available, and the targets for treatment of recurrence are not well defined. The Aim of this paper is to find the therapeutic target.

Split-based elevational localization of photoacoustic guidewire tip by 1D array probe using spatial impulse response.

. Photoacoustic emitters on the tip of a therapeutic device have been intensively studied for echo-guided intervention purposes. In this study, a novel method for localizing the guidewire tip emitter in the elevation direction using a 1D array probe is proposed to resolve the issue of the tip potentially deviating from the ultrasound-imaged plane.

Targeting cholesterol biosynthesis for AT/RT: comprehensive expression analysis and validation in newly established AT/RT cell line.

Atypical teratoid/rhabdoid (AT/RT) is a rare and highly malignant tumor of the central nervous system (CNS). It is most commonly found in children less than 5 years of age and is associated with inactivation of loss of function of SMARCB1/INI1. An experimental model for AT/RT is necessary to develop new and effective therapies.

Ca storage function is altered in the sarcoplasmic reticulum of skeletal muscle lacking mitsugumin 23.

Mitsugumin 23 (MG23) has been identified as a ball-shaped cation channel in the sarcoplasmic reticulum (SR) but its physiological role remains unclear. This study aimed to examine the contribution of MG23 to Ca storage function in skeletal muscle by using -knockout () mice. There was no difference in the isometric specific force of the extensor digitorum longus (EDL) and soleus (SOL) muscles between and wild-type (Wt) mice.

Epidemiological Study of Metastatic Brain Tumors in Miyazaki Prefecture: A Regional 10-year Survey in Southern Japan.

Advances in cancer treatment have improved the survival of patients with cancer, with a concomitant increase in the proportion of patients with metastatic brain tumors (MBTs). In this study, we used cancer registries established in Japan after 2016 and available patient data by organ in order to conduct an accurate epidemiological study. To the best of our knowledge, this is the first study to report on the detailed epidemiological data on MBT at the prefectural level in Japan using the Miyazaki Brain Tumor Database and Miyazaki Cancer Registry.

Atypical cell death and insufficient matrix organization in long-bone growth plates from Tric-b-knockout mice.

TRIC-A and TRIC-B proteins form homotrimeric cation-permeable channels in the endoplasmic reticulum (ER) and nuclear membranes and are thought to contribute to counterionic flux coupled with store Ca release in various cell types. Serious mutations in the TRIC-B (also referred to as TMEM38B) locus cause autosomal recessive osteogenesis imperfecta (OI), which is characterized by insufficient bone mineralization. We have reported that Tric-b-knockout mice can be used as an OI model; Tric-b deficiency deranges ER Ca handling and thus reduces extracellular matrix (ECM) synthesis in osteoblasts, leading to poor mineralization.

Structure, Function, and Regulation of the Junctophilin Family.

In both excitable and nonexcitable cells, diverse physiological processes are linked to different calcium microdomains within nanoscale junctions that form between the plasma membrane and endo-sarcoplasmic reticula. It is now appreciated that the junctophilin protein family is responsible for establishing, maintaining, and modulating the structure and function of these junctions. We review foundational findings from more than two decades of research that have uncovered how junctophilin-organized ultrastructural domains regulate evolutionarily conserved biological processes.

Massive horizontal gene transfer and the evolution of nematomorph-driven behavioral manipulation of mantids.

To complete their life cycle, a wide range of parasites must manipulate the behavior of their hosts. This manipulation is a well-known example of the "extended phenotype," where genes in one organism have phenotypic effects on another organism. Recent studies have explored the parasite genes responsible for such manipulation of host behavior, including the potential molecular mechanisms.

Mouse methylation profiles for leukocyte cell types, and estimation of leukocyte fractions in inflamed gastrointestinal DNA samples.

Precise analysis of tissue DNA and RNA samples is often hampered by contaminating non-target cells whose amounts are highly variable. DNA methylation profiles are specific to cell types, and can be utilized for assessment of the fraction of such contaminating non-target cells. Here, we aimed 1) to identify methylation profiles specific to multiple types of mouse leukocytes, and 2) to estimate the fraction of leukocytes infiltrating inflamed tissues using DNA samples.

The biophysical properties of TRIC-A and TRIC-B and their interactions with RyR2.

Trimeric intracellular cation channels (TRIC-A and TRIC-B) are thought to provide counter-ion currents to enable charge equilibration across the sarco/endoplasmic reticulum (SR) and nuclear membranes. However, there is also evidence that TRIC-A may interact directly with ryanodine receptor type 1 (RyR1) and 2 (RyR2) to alter RyR channel gating. It is therefore possible that the reverse is also true, where the presence of RyR channels is necessary for fully functional TRIC channels.

Precancerous nature of intestinal metaplasia with increased chance of conversion and accelerated DNA methylation.

Objective: The presence of intestinal metaplasia (IM) is a risk factor for gastric cancer. However, it is still controversial whether IM itself is precancerous or paracancerous. Here, we aimed to explore the precancerous nature of IM by analysing epigenetic alterations.

Distinct patterns of copy number alterations may predict poor outcome in central nervous system germ cell tumors.

We have previously reported that 12p gain may predict the presence of malignant components and poor prognosis for CNS germ cell tumor (GCT). Recently, 3p25.3 gain was identified as an independent predictor of poor prognosis for testicular GCT.
