Kamishoyosan Alleviates Anxiety-like Behavior in a Premenstrual Syndrome Rat Model.

Kamishoyosan (KSS) is a traditional Japanese Kampo medicine that is prescribed for hormonal change-induced mood disorders including premenstrual syndrome (PMS). In clinical studies, KSS exhibited ameliorative effects on mood symptoms of PMS, such as anxiety and irritability. However, the mechanism underlying the beneficial effects of KSS is unclear.

Solid-state cross-coupling reactions of insoluble aryl halides under polymer-assisted grinding conditions.

In this study, polymer-assisted grinding (POLAG), a ball-milling technique based on the use of polymer additives, was applied to mechanochemical solid-state Suzuki-Miyaura cross-coupling reactions of insoluble aryl halides. We found that the efficiency of this challenging solid-state cross-coupling was improved by the addition of polytetrafluoroethylene (PTFE) as a POLAG additive under high-temperature ball-milling conditions. Our results suggest that POLAG is a promising approach for controlling the reactivity of insoluble substrates that are barely reactive under conventional solution-based conditions.

Clinical Outcomes of Inside Stents and Conventional Plastic Stents as Bridge-to-Surgery Options for Malignant Hilar Biliary Obstruction.

Background: The appropriate method of preoperative endoscopic biliary drainage (EBD) for cholangiocarcinoma with hilar biliary obstruction remains controversial. The inside-stent technique is a method of placing plastic stents entirely inside the bile duct. Several studies of patients with unresectable stage have reported longer stent patency compared with conventional endoscopic biliary stenting (EBS).

Utility of Fine-Gauge Balloon Catheter for EUS-Guided Hepaticogastrostomy.

Background And Purpose: During endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), tract dilation is one of the most important steps, and the placement of conventional metal stents with 8.5 Fr delivery devices is difficult due to the large outer shape of the device. Fine-gauge balloon catheters have become popular because of their stricture penetration ability and ease of dilation.

The Novel Gabapentinoid Mirogabalin Prevents Upregulation of α2δ-1 Subunit of Voltage-Gated Calcium Channels in Spinal Dorsal Horn in a Rat Model of Spinal Nerve Ligation.

Gabapentinoids are specific ligands for the αδ-1 subunit of voltage-gated calcium channels. This class of drugs, including gabapentin and pregabalin, exert various pharmacological effects and are widely used for the treatment of epilepsy, anxiety, and chronic pain. The mechanism of action of gabapentinoids involves both direct modulation of calcium channel kinetics and inhibition of channel trafficking and expression, which contribute to the above pharmacological effects.

Difference between morning and evening blood pressure at home and nocturnal hypoxia in the general practitioner-based J-HOP study.

The aim of this study was to determine the independent association of nocturnal hypoxia with morning minus evening home blood pressure (MEdif) in a cohort of outpatients with at least one cardiovascular risk. A total of 1053 participants underwent home blood pressure (BP) portable pulse oximetry measurements, and 147 (14%) had an MEdif ≥20 mmHg, where MEdif was defined as the difference between morning and evening home systolic BP. When participants were divided into quartiles according to the lowest oxygen saturation (SpO) during the nighttime, those in the lowest quartile (range, 54-79%) were significantly more likely to have MEdif ≥20 mmHg than those in the top quartile (range, 89-97%) (adjusted odds ratio, 1.

Macadamia nut-specific IgE levels for predicting anaphylaxis.

Background: Despite the high risk of anaphylaxis in patients with a macadamia nut allergy (MdA), little is known about the significance of macadamia nut-specific immunoglobulin E (Md-sIgE). Thus, this study aimed to investigate the utility of Md-sIgE for predicting anaphylaxis.

Methods: Children with suspected MdA who visited our hospital were included.

Quantitative high-throughput analysis of tumor infiltrating lymphocytes in breast cancer.

In breast cancer (BC), the development of cancer immunotherapy including immune checkpoint inhibitors has progressed. Tumor infiltrating lymphocytes (TILs) is one of the important factors for an immune response between tumor cells and immune cells in the tumor microenvironment, and the presence of TILs has been identified as predictors of response to chemotherapy. However, because complex mechanisms underlies the crosstalk between immune cells and cancer cells, the relationship between immune profiles in the tumor microenvironment and the efficacy of the immune checkpoint blocked has been unclear.

Right Kidney Position for Laparoscopic Liver Resection of Tumors Located in the Posterosuperior Region.

Background: Laparoscopic liver resection (LLR) for tumors located in posterosuperior (PS) region of the liver (segment 7 or 8) is extremely challenging. Several techniques have been proposed; however, no standard procedure has yet been established. The aim of this study was to present and discuss the usefulness of the right kidney position as a unique idea of surgical position in LLR for tumors located in the PS region.

Zinc chelator treatment in crush syndrome model mice attenuates ischemia-reperfusion-induced muscle injury due to suppressing of neutrophil infiltration.

In crush syndrome, massive muscle breakdown resulting from ischemia-reperfusion muscle injury can be a life-threatening condition that requires urgent treatment. Blood reperfusion into the ischemic muscle triggers an immediate inflammatory response, and neutrophils are the first to infiltrate and exacerbate the muscle damage. Since free zinc ion play a critical role in the immune system and the function of neutrophils is impaired by zinc depletion, we hypothesized that the administration of a zinc chelator would be effective for suppressing the inflammatory reaction at the site of ischemia-reperfusion injury and for improving of the pathology of crush syndrome.

Efficacy and safety of carboplatin with nab-paclitaxel versus docetaxel in older patients with squamous non-small-cell lung cancer (CAPITAL): a randomised, multicentre, open-label, phase 3 trial.

Background: In Japan, docetaxel, a cytotoxic monotherapy, is the standard drug administered to older patients with advanced non-small-cell lung cancer (NSCLC). Carboplatin plus nab-paclitaxel has shown a high objective response rate in patients with squamous histology and was suggested to improve overall survival in patients aged 70 years and older. The CAPITAL trial aimed to assess the safety and efficacy of carboplatin plus nab-paclitaxel versus docetaxel as first-line therapy for patients aged 70 years and older with advanced squamous NSCLC.

Black pleural effusion caused by a pancreaticopleural fistula associated with autoimmune pancreatitis: A case report.

Rationale: Black pleural effusion is a rare medical condition and a diagnostic marker. Pancreaticopleural fistula is one of the causes of black pleural effusion. Thus far, black pleural effusions caused by pancreaticopleural fistulae have mostly been reported in patients with alcohol-induced chronic pancreatitis.

Symbiosis between Patescibacteria and Archaea Discovered in Wastewater-Treating Bioreactors.

Each prokaryotic domain, Bacteria and Archaea, contains a large and diverse group of organisms characterized by their ultrasmall cell size and symbiotic lifestyles (potentially commensal, mutualistic, and parasitic relationships), namely, Patescibacteria (also known as the Candidate Phyla Radiation/CPR superphylum) and DPANN archaea, respectively. Cultivation-based approaches have revealed that . Patescibacteria and DPANN symbiotically interact with bacterial and archaeal partners and hosts, respectively, but that cross-domain symbiosis and parasitism have never been observed.
