The powerful potential of amino acid menthyl esters for anti-inflammatory and anti-obesity therapies.

Our newly developed menthyl esters of valine and isoleucine exhibit anti-inflammatory properties beyond those of the well-known menthol in macrophages stimulated by lipopolysaccharide (LPS) and in a mouse model of colitis induced by sodium dextran sulfate. Unlike menthol, which acts primarily through the cold-sensitive TRPM8 channel, these menthyl esters displayed unique mechanisms that operate independently of this receptor. They readily penetrated target cells and efficiently suppressed LPS-stimulated tumour necrosis factor-alpha (Tnf) expression mediated by liver X receptor (LXR), a key nuclear receptor that regulates intracellular cholesterol and lipid balance.

Spin-State Control of Shallow Single NV Centers in Hydrogen-Terminated Diamond.

The ability to control the charge and spin states of nitrogen-vacancy (NV) centers near the diamond surface is of pivotal importance for quantum applications. Hydrogen-terminated diamond is promising for long spin coherence times and ease of controlling the charge states due to the low density of surface defects. However, it has so far been challenging to create negatively charged single NV centers with controllable spin states beneath a hydrogen-terminated surface because atmospheric adsorbates that act as acceptors induce surface holes.

Metabolic engineering of betacyanin in vegetables for anti-inflammatory therapy.

Betalains, which consist of the subgroups betaxanthins and betacyanins, are hydrophilic pigments that have classically been used for food colorants. Owing to their strong antioxidant property, their usefulness for application for therapeutic use is also expected. In addition, as betalains are mainly naturally available from plants of the order Caryophyllales, including beet (Beta vulgaris), metabolic engineering for betalain production in crops such as vegetables, fruits and cereals may provide new food resources useful for healthcare.

Stabilization of VEGF i-motif structure by CpG methylation.

The intercalated motif (i-motif) is a non-canonical nucleic acid structure formed by intercalated hemi-protonated cytosine base pairs (C-C) under acidic conditions. The i-motif structure formation is involved in biological processes such as transcription regulation. Therefore, the identification of factors controlling i-motif formation is important in elucidating the cellular functions it controls.

Electron tomography imaging methods with diffraction contrast for materials research.

Transmission electron microscopy (TEM) and scanning transmission electron microscopy (STEM) enable the visualization of three-dimensional (3D) microstructures ranging from atomic to micrometer scales using 3D reconstruction techniques based on computed tomography algorithms. This 3D microscopy method is called electron tomography (ET) and has been utilized in the fields of materials science and engineering for more than two decades. Although atomic resolution is one of the current topics in ET research, the development and deployment of intermediate-resolution (non-atomic-resolution) ET imaging methods have garnered considerable attention from researchers.

We herein report the first documented case of acute hypersensitivity pneumonitis in which Candida guilliermondii was the possible causative organism. A young Japanese woman presented to our hospital with relapsing respiratory symptoms accompanied by high fever. A detailed interview revealed that the onset of the symptoms occurred shortly after using a humidifier in her home.

The Clinical and Hormonal Characteristics of Primary Adrenal Lymphomas: The Necessity of Early Detection of Adrenal Insufficiency.

Objective To analyze the clinical and endocrine characteristics of patients with primary adrenal lymphoma. Patients We retrospectively reviewed the cases of five patients with primary adrenal lymphoma who were treated in our hospital between April 2004 and March 2015. We investigated the characteristics of the clinical and pathological findings, treatment, prognosis and complications of adrenal insufficiency.

Single-channel 3.84 Tbit/s, 64 QAM coherent Nyquist pulse transmission over 150 km with a spectral efficiency of 10.6 bit/s/Hz.

We report a polarization-multiplexed 320 Gbaud, 64 QAM coherent Nyquist pulse transmission with a frequency-stabilized mode-locked laser and a modified digital back-propagation method for pulse transmission. Using a combination consisting of a mode-locked laser and a pulse shaper, we obtained a Nyquist pulse with a high OSNR of 51 dB. We achieved error free operation under a back-to-back condition with the OSNR improvement.

Combined Effects of Androgen and Growth Hormone on Osteoblast Marker Expression in Mouse C2C12 and MC3T3-E1 Cells Induced by Bone Morphogenetic Protein.

Osteoblasts undergo differentiation in response to various factors, including growth factors and steroids. Bone mass is diminished in androgen- and/or growth hormone (GH)-deficient patients. However the functional relationship between androgen and GH, and their combined effects on bone metabolism, remains unclear.

A Rare Case of Diffuse Large B-cell Lymphoma in a Patient with IgG4-Related Autoimmune Pancreatitis.

A 61-year-old Japanese man with IgG4-related autoimmune pancreatitis was referred to our hospital because of perspiration during food intake. Abdominal computed tomography (CT) with contrast media revealed multiple mesenteric lymphadenopathies. An open surgical abdominal biopsy and subsequent histopathological analysis revealed abnormally large lymphoid cells that were negative for CD3, CD5, and c-myc and positive for CD20 and bcl-2, leading to a diagnosis of diffuse large B-cell lymphoma.

Increased Serum KL-6 Levels Induced by Pulmonary Mycobacterium Avium Complex Infection in a Patient with RA-associated Lung Disease.

KL-6 is a glycoprotein found predominantly on type II pneumocytes and alveolar macrophages, and often shows increased serum levels in patients with interstitial pneumonia. We report a case of mycobacterium avium complex (MAC) infection whose disease activity was correlated with KL-6 levels in serum. During treatment of rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) with prednisolone, chest image findings improved in association with decreased KL-6 levels.

Endoscopic detection of the gastric lesions of peripheral T-cell lymphoma.

An 82-year-old Japanese man presented with a gastric involvement of peripheral T-cell lymphoma, not otherwise specified. Although gastrointestinal lesions were not detected on computed tomography, oesophagogastroduodenoscopy revealed a slight elevation of the gastric mucosa, with changes in mucosal colour and the presence of abnormal microvessels. This led to the prompt detection of gastric involvement in lymphoma.

Actinomyces turicensis Bacteremia Secondary to Pyometra.

We herein present a rare case of Actinomyces turicensis bacteremia that was caused by pyometra. The patient was successfully treated with transvaginal drainage and antibiotic therapy. A literature review in MEDLINE showed that there have been only 8 previously reported cases of A.

Complication of chronic eosinophilic pneumonia in an elderly patient with Sjögren syndrome.

An 81-year-old Japanese male with primary Sjögren syndrome (pSS) developed a low-grade fever and productive cough which were refractory to antibiotic therapy. Based on the high level of eosinophils observed in his bronchial alveolar lavage, he was diagnosed with chronic eosinophilic pneumonia (CEP) and successfully treated by oral prednisolone. Interstitial lung diseases associated with pSS (pSS-ILDs) usually present as nonspecific interstitial pneumonia or usual interstitial pneumonia; therefore, the present case is extremely unique in that the patient's condition was complicated with CEP.

A paraganglioma in a hypertensive patient with unilateral renal hypoplasia.

We report the case of a 46-year-old hypertensive Japanese female with renal insufficiency related to unilateral renal hypoplasia. The patient was found to have developed paraganglioma in the retroperitoneal space over a 5-year period. Catecholamine-producing tumors are not usually recognized as conditions associated with renal hypoplasia.

Myopathy and eosinophilic pneumonia coincidentally induced by treatment with daptomycin.

A 34-year-old man with 22q11.2 deletion syndrome (DiGeorge syndrome) concurrently suffered from myopathy and eosinophilic pneumonia shortly after receiving daptomycin (DAP) for right-sided infective endocarditis. The simultaneous occurrence of these phenomena in relation to DAP therapy has not been previously well described.

Fosfomycin for the treatment of prostate infection.

A 69-year-old man with diabetes mellitus was diagnosed with a prostate abscess.
