Chronic activation of β-adrenergic receptors leads to tissue water and electrolyte retention.

β-Adrenergic receptors (β-ARs) are expressed on the membranes of various cell types, and their activation affects body water balance by modulating renal sodium and water excretion, cardiovascular function, and metabolic processes. However, β-AR-associated body fluid imbalance has not been well characterized. In the present study, we hypothesized that chronic β-AR stimulation increases electrolyte and water content at the tissue level.

18-β-Glycyrrhetinic Acid Promotes Hair Growth by Stimulating the Proliferation of Dermal Papilla Cells and Outer Root Sheath Cells, and Extends the Anagen Phase by Inhibiting 5α-Reductase.

18-β-Glycyrrhetinic acid, a major component of licorice, stimulated the proliferation of both dermal papilla cells and outer root sheath cells isolated from human hair follicles. Thus, suggesting that this compound promotes hair growth. Furthermore, this compound inhibited the activity of testosterone 5α-reductase, an enzyme responsible for converting androgen to dihydroandrogen, with an IC of 137.

Ginsenosides in Panax ginseng Extract Promote Anagen Transition by Suppressing BMP4 Expression and Promote Human Hair Growth by Stimulating Follicle-Cell Proliferation.

Studies showing that Panax ginseng promotes hair growth have largely been conducted using mice; there are few reports on how P. ginseng affects human hair growth. In particular, little is known about its effect on the telogen to anagen transition.

Highly efficient Runx1 enhancer eR1-mediated genetic engineering for fetal, child and adult hematopoietic stem cells.

A cis-regulatory genetic element which targets gene expression to stem cells, termed stem cell enhancer, serves as a molecular handle for stem cell-specific genetic engineering. Here we show the generation and characterization of a tamoxifen-inducible CreER transgenic (Tg) mouse employing previously identified hematopoietic stem cell (HSC) enhancer for Runx1, eR1 (+24 m). Kinetic analysis of labeled cells after tamoxifen injection and transplantation assays revealed that eR1-driven CreER activity marks dormant adult HSCs which slowly but steadily contribute to unperturbed hematopoiesis.

Eosinophilic cystitis mimicking hemorrhagic cystitis in relapsed follicular lymphoma.

Eosinophilic cystitis (EC) is a rare and non-infectious inflammatory disorder characterized by transmural infiltration of eosinophils in the bladder wall. The diagnosis of EC is made only by the pathophysiological findings. Because the urinary symptoms of EC are quite similar to other urinary tract disorders including hemorrhagic cystitis (HC), it can be misdiagnosed or left undiagnosed.

Non-valvular Infective Endocarditis Caused by Sarocladium kiliense in an Immunocompromised Patient with Aplastic Anemia.

Sarocladium kiliense is ubiquitous in the human environment and is an emerging opportunistic pathogen, especially among immunocompromised hosts. A 77-year-old man diagnosed with aplastic anemia suffered from non-valvular endocarditis. After he passed away, fungal hyphae were observed in several lesions on a postmortem examination.

Resection of liver metastasis from submandibular gland carcinoma five years after the primary operation: A case.

Introduction: Liver metastasis of submandibular gland carcinoma is not uncommon, yet its optimal management is still unclear. We report a case of resection of liver metastasis from submandibular gland carcinoma five years after the primary operation.

Case Presentation: The patient was a 76-year-old male who had undergone resection of primary adenoid cystic carcinoma of the submandibular gland in 2012.

The segment IV approach: a useful method for achieving the critical view of safety during laparoscopic cholecystectomy in patients with anomalous bile duct.

Background: The critical view of safety (CVS) method can be achieved by avoiding vasculo-biliary injury resulting from misidentification during laparoscopic cholecystectomy (LC). Although achieving the CVS has become popular worldwide, there is no established standardized technique to achieve the CVS in patients with an anomalous bile duct (ABD). We recently reported our original approach for securing the CVS using a new landmark, the diagonal line of the segment IV of the liver (D-line).

Exploration of an odorous aldehydes and ketones produced by Uroglena americana using high resolution mass spectrometry, GC-Olfactometry, and multivariate analysis.

Off-flavor events in tap water have been reported from various regions of Japan. Fishy smell is the second most common off-flavor in Japan and Uroglena americana (U. americana) is known to be a major contributor to the smell.

Segment IV approach for difficult laparoscopic cholecystectomy.

Although achieving the critical view of safety (CVS) is useful for avoiding vasculobiliary injury during laparoscopic cholecystectomy (LC), the CVS cannot always be achieved in cases of severe cholecystitis because of technical difficulties. Herein, we focused on segment IV of the liver and its diagonal line (D-line) as a feasible landmark for carrying out difficult LC. The D-line connects the right dorsal and left ventral corners of segment IV and is used as the vectoral landmark, which is where the gallbladder is first dissected to achieve CVS without misidentification.

New Concept Air Conditioning System for the Operating Room to Minimize Patient Cooling and Surgeon Heating: A Historical Control Cohort Study.

Background: Intraoperative hypothermia is a common adverse event. For avoiding the complication due to hypothermia, many warming devices and methods have been used in perioperative period. It has been reported that more patients undergoing laparoscopic surgery tend to have hypothermia than with open surgery.

Clinical Significance of Tumor-Infiltrating T Cells and Programed Death Ligand-1 in Patients with Pancreatic Cancer.

The associations of the immunological status of the pancreatic ductal adenocarcinoma (PDA) microenvironment with prognosis were assessed. A high tumor-infiltrating lymphocyte (TIL) density was associated with a better prognosis. Importantly, even with a high density of TILs, the PDA cells with programed cell death-ligand 1 (PD-L1) expression showed a worse prognosis than the patients with negative PD-L1 expression.

Impact of Bile Exposure Time on Organ/space Surgical Site Infections After Pancreaticoduodenectomy.

Background/aim: Organ/space surgical site infections (SSIs) are critical complications of pancreaticoduodenectomy. We investigated the impact of the time between division of the common hepatic duct and completion of biliary reconstruction [bile exposure (BE) time] on the occurrence of post-pancreaticoduodenectomy organ/space SSI.

Patients And Methods: Sixty-one patients who underwent pancreaticoduodenectomy were retrospectively studied.

A new highly sensitive real-time quantitative-PCR method for detection of BCR-ABL1 to monitor minimal residual disease in chronic myeloid leukemia after discontinuation of imatinib.

Tyrosine kinase inhibitors (TKIs) targeting the BCR-ABL1 fusion protein, encoded by the Philadelphia chromosome, have drastically improved the outcomes for patients with chronic myeloid leukemia (CML). Although several real-time quantitative polymerase chain reaction (RQ-PCR) kits for the detection of BCR-ABL1 transcripts are commercially available, their accuracy and efficiency in laboratory practice require reevaluation. We have developed a new in-house RQ-PCR method to detect minimal residual disease (MRD) in CML cases.

Laparoscopic treatment of a solitary fibrous tumor originating in the cystic plate.

Background: Solitary fibrous tumor (SFT) is a rare mesenchymal tumor originating from the tissue underlying the mesothelial layer of the pleura or mediastinum. Other reported sites include the upper respiratory tract, orbit, thyroid, peritoneum, and central nervous system.

Case Presentation: We describe a case of a 7 cm SFT that originated in the cystic plate.

A case of portal vein thrombosis caused by blunt abdominal trauma in a patient with low protein C activity.

Portal vein thrombosis (PVT) is caused by several conditions including infection, malignancies, surgery, medications, and coagulation disorders. However, PVT caused by low-energy injury is very rare. A 51-year-old man visited a clinic with a 2-day history of abdominal pain following blunt abdominal trauma.

Guanylyl Cyclase A in Both Renal Proximal Tubular and Vascular Endothelial Cells Protects the Kidney against Acute Injury in Rodent Experimental Endotoxemia Models.

What We Already Know About This Topic: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Natriuretic peptides are used, based on empirical observations, in intensive care units as antioliguric treatments. We hypothesized that natriuretic peptides prevent lipopolysaccharide-induced oliguria by activating guanylyl cyclase A, a receptor for natriuretic peptides, in proximal tubules and endothelial cells.

Methods: Normal Sprague-Dawley rats and mice lacking guanylyl cyclase A in either endothelial cells or proximal tubular cells were challenged with lipopolysaccharide and assessed for oliguria and intratubular flow rate by intravital imaging with multiphoton microscopy.

Tying modified clinch knots during single-incision laparoscopic surgery.

Introduction: Recent advances in single-incision laparoscopic surgery (SILS) have caused increased difficulties when tying knots because of the limited working space. Although extracorporeal knot-tying techniques may be a practical alternative choice in SILS, it is not always appropriate. For example, sliding resistance may be encountered when tying knots for a Z-shaped suture, and it could damage the sutured tissue.

Successful Autologous Hematopoietic Stem Cell Transplantation Followed by Bortezomib Maintenance in a Patient with Relapsed CD138-low Multiple Solitary Plasmacytomas Harboring a 17p Deletion.

Solitary bone plasmacytoma (SBP) tends to progress to multiple myeloma (MM); however, progression to multiple solitary plasmacytomas (MSP) is rare. We report a case of CD138-low MSP with 17p deletion in a patient with relapsed SBP. 17p deletion is associated with a poor outcome in patients with MM, and the low expression of CD138 in myeloma cells is associated with drug resistance and a poor prognosis.
