Introduction: Antimicrobial treatment disrupts human microbiota. The effects of lascufloxacin (LSFX), a new fluoroquinolone, on human microbiota remains unknown. Therefore, in this study, we aimed to evaluate the effects of LSFX administration on the gut and salivary microbiota of healthy participants and those with pneumonia.

Methods: We retrospectively analyzed 373 patients undergoing RARC with ileal conduit at 11 institutions in Japan between April 2018 and December 2021. Propensity score weighting was performed to adjust for confounding factors such as age, sex, body mass index, performance status, American Society of Anesthesiologists score, previous abdominal surgery, neoadjuvant chemotherapy, and preoperative high T stage (≥ cT3) and high N stage (≥ cN1).
Objective: The employment outcomes of childhood-onset drug-resistant epilepsy (DRE) has not been studied enough. The aim of this retrospective cohort study is to investigate the employment outcomes of childhood-onset DRE in June 2022 and identify the risk factors associated with non-employment.
Materials And Methods: The sample consisted of 65 participants ≥18 years of age with a history of childhood-onset DRE.
Introduction: Children with infantile epileptic spasms syndrome (IESS) are likely to experience poor outcomes. Researchers have investigated the factors related to its long-term prognosis; however, none of them developed a predictive model.
Objective: This study aimed to clarify the factors that influence the long-term prognosis of seizures and their development and to create a prediction model for IESS.
Introduction: Infantile epileptic spasms syndrome (IESS) is characterized by epileptic spasms, regardless of hypsarrhythmia on electroencephalogram or neurodevelopmental delay. In Japan, pyridoxal 5'-phosphate (PLP) is often used as the first-line treatment for IESS because it is effective in a certain number of patients. Although several studies have reported serious adverse events following PLP treatment, no study has investigated the risk factors for such occurrences.

Recently, navigation procedures with indocyanine green (ICG) have been reported. Furthermore, we previously reported the possibility of detecting BLs with high sensitivity during hepatectomy by administering ICG into the bloodstream, which is quickly excreted in the bile.
View Article and Find Full Text PDFIn eukaryotes, CREB-binding protein (CBP), a coactivator of CREB, functions both as a platform for recruiting other components of the transcriptional machinery and as a histone acetyltransferase (HAT) that alters chromatin structure. We previously showed that the transcriptional activity of cAMP-responsive element binding protein (CREB) plays a crucial role in neuronal plasticity in the pond snail Lymnaea stagnalis. However, there is no information on the molecular structure and HAT activity of CBP in the Lymnaea central nervous system (CNS), hindering an investigation of its postulated role in long-term memory (LTM).

Distinguishing between true and paradoxical worsening of postoperative ophthalmic symptoms using a less-invasive modality is often difficult. Here, we report a case of true worsening of neuro-ophthalmic symptom by recurrent CSDAVF detected by venous-arterial spin labeling (ASL) on magnetic resonance imaging.

Current hormonal treatments and low-dose oral contraceptives (OCs) used as a first-choice drug for primary symptoms, however, have a high incidence of adverse events without improving patients' satisfaction. We evaluated the efficacy of TSS as additional treatment on the quality of life (QOL) of patients taking OCs with reduced therapeutic satisfaction.

However, the two-dimensional X-ray fluoroscopic images do not provide real-time guidance. The authors developed a new real-time three-dimensional (3D) navigation technique for FESS that entails the use of intraoperative cone beam computed tomography (CBCT) in a hybrid operating room (OR).

Methods: We retrospectively analyzed the demographics, complications, peri-operative and oncological outcomes of 253 consecutive patients with bladder cancer who underwent RARC at 34 institutions in Japan between April 2009 and March 2017. The patients were assigned to groups according to ages at surgery of < 70 (younger; n = 125) and ≥ 70 (older; n = 128) years.
Aims: Dydrogesterone is a retro-progesterone preparation widely used for over a half century. We sought to evaluate the efficacy and safety of dydrogesterone in Japanese women with dysmenorrhea.
Methods: This study was conducted as an open-label, single-arm, multicenter study.
Background: SR-16234 is a selective estrogen receptor modulator (SERM) structurally different from approved SERM and has been reported to have estrogen receptor (ER) α antagonistic activity and strong affinity with a weak partial agonistic activity to ERβ receptor. SR-16234 showed strong inhibitory effects on transplanted endometrial cysts in the endometriosis model of rat and mouse. In this clinical trial, efficacy and safety of SR-16234 have been evaluated in endometriosis patients.

In the present study, we examined whether there are interstrain differences in the ability to form LTM following these two types of conditioning. A strain of (TC1) collected in Alberta, Canada exhibits superior memory-forming ability following aerial respiratory operant conditioning compared to a laboratory-reared strain of from Netherlands known as the Dutch strain.

Here, we identified mRNAs expressed in central nervous system that encode two G-protein-coupled receptors ( CBr-like 1 and 2) that structurally resemble mammalian cannabinoid receptors (CBrs). We found that injection of a mammalian CBr agonist WIN 55,212-2 (WIN 55) into the snail before operant conditioning obstructed learning and memory formation.

The effects of environmentally relevant stressors, such as low environmental calcium and crowding, on learning and memory have previously been described in a laboratory-reared 'average' strain of (i.e.
View Article and Find Full Text PDFThe pond snail Lymnaea stagnalis can acquire conditioned taste aversion (CTA) as a long-term memory. CTA is caused by the temporal pairing of a stimulus, such as sucrose (the conditioned stimulus; CS), with another stimulus, such as electric shock (the unconditioned stimulus; US). Previous studies have demonstrated changes in both cellular and molecular properties in a pair of neurons known as the cerebral giant cells (CGCs), suggesting that these neurons play a key role in CTA.

Stress alters the ability to form and maintain memory, but whether the causal neuronal mechanisms underling memory formation in PTSD are similar to normal memory is not clear. Here, we use Lymnaea to study the effects of combinations of stressors on the quality of the formed memory state.

Lymnaea exposed to crayfish effluent (CE) gain an enhanced ability to form long-term memory (LTM). We test the hypothesis that a single CE exposure and operant conditioning training leads to long lasting changes in the capability of snails to form LTM when tested in pond water four weeks later. We trained both juvenile and adult snails with a single 0.

After successful training, feeding behavior is significantly suppressed in response to CS presentation.

Insulin is well known as a hormone regulating glucose homeostasis across phyla. Although there are insulin-independent mechanisms for glucose uptake in the mammalian brain, which had contributed to a perception of the brain as an insulin-insensitive organ for decades, the finding of insulin and its receptors in the brain revolutionized the concept of insulin signaling in the brain. However, insulin's role in brain functions, such as cognition, attention, and memory, remains unknown.

Pre-exposure of snails to the protein kinase C (PKC) α and ε activator bryostatin (Bryo) facilitated STM formation in that only 5 paired CS-US trials were required. Typically 20 paired presentations of the CS-US are required for formation of STM and LTM.
