Age Is a Risk Factor for Olaparib Dose Modification and Discontinuation in Patients With Ovarian Cancer.

Background/aim: Olaparib, a poly (ADP-ribose) polymerase inhibitor, is widely used as maintenance therapy for ovarian cancer. Dose modification, such as dose reduction and treatment interruption, are frequently performed to manage adverse events (AEs) of olaparib. By identifying patients at high risk for dose modification before administration, interventions related to appropriate control of AEs can be implemented.

Cervical lymphoepithelioma-like carcinoma with deficient mismatch repair and loss of SMARCA4/BRG1: a case report and five related cases.

Background: We encountered a cervical lymphoepithelial carcinoma (LEC) possessing a predominantly solid architecture with deficient mismatch repair (dMMR) and loss of expression of the SWI/SNF (SWItch/Sucrose Non-Fermentable) chromatin remodeling complex subunit. This is the first case report of LEC with dMMR and loss of SWI/SNF complex subunit.

Case Presentation: A 34-year-old woman presented at our hospital with menstrual irregularities and abnormal vaginal bleeding.

Androgens enhance the ability of intratumoral macrophages to promote breast cancer progression.

Androgens are produced locally in breast carcinoma tissues by androgen‑producing enzymes such as 5α‑reductase type 1 (5αRed1) and affect not only breast cancer cells but the tumor microenvironment as well. Tumor‑associated macrophages (TAMs) are primary components of the tumor microenvironment and contribute to tumor progression. Although previous studies suggest that androgen/androgen receptor (AR) signaling in macrophages has important roles in human diseases, androgen action on TAMs has remained largely unknown.

[Optical Erasure of the Synaptic Ensemble that Underlies Learning and Memory].

Dentritic spines are small membrane protrusions. Their regulation is thought to be important for memory storage, but the links between dentric spines and memory have been largely correlational because of a luck of techniques for manipulating individual spines. To overcome this problem, we have developed a novel synaptic optoprobe, AS-PaRac1, which is unique not only because it specifically labels recently potentiated spines, but also because it becomes possible to selectively shrink spines containing AS-PaRac1.

A BOLD-fMRI study of cerebral activation induced by injection of algesic chemical substances into the anesthetized rat forepaw.

This study was performed to examine whether the brain activities induced by noxious algesic chemical substances in anesthetized animals could be detected by blood oxygen-level-dependent functional magnetic resonance imaging (BOLD-fMRI). Multislice gradient echo images of the primary somatosensory cortex were obtained using a 7.05 T superconducting system and a one-turned surface coil centered over the primary somatosensory cortex of the 1.

Lipase-catalyzed biodiesel production from waste activated bleaching earth as raw material in a pilot plant.

The production of fatty acid methyl esters (FAMEs) from waste activated bleaching earth (ABE) discarded by the crude oil refining industry using lipase from Candida cylindracea was investigated in a 50-L pilot plant. Diesel oil or kerosene was used as an organic solvent for the transesterification of triglycerides embedded in the waste ABE. When 1% (w/w) lipase was added to waste ABE, the FAME content reached 97% (w/w) after reaction for 12 h at 25 degrees C with an agitation rate of 30 rpm.

Efficient production of fatty acid methyl ester from waste activated bleaching earth using diesel oil as organic solvent.

Fatty acid methyl ester (FAME) production from waste activated bleaching earth (ABE) discarded by the crude oil refining industry was investigated using fossil fuel as a solvent in the esterification of triglycerides. Lipase from Candida cylindracea showed the highest stability in diesel oil. Using diesel oil as a solvent, 3 h was sufficient to obtain a yield of approximately 100% of FAME in the presence of 10% lipase from waste ABE.
