Effect of kuratsuki Kocuria on sake's taste varies depending on the sake yeast strain used in sake brewing.

Although sake yeast mainly produces the taste of sake, sake brewery-inhabiting (kuratsuki) bacteria affect the taste of sake. Thus, kuratsuki bacteria may alter the metabolism of sake yeast through interactions between kuratsuki bacteria and sake yeast. This study aimed to confirm the effects of the combination of kuratsuki Kocuria TGY1127_2 and different sake yeast strains, AK25, K901, and K1801 on the taste of sake.

Effect of kuratsuki Kocuria on sake brewing in different koji conditions.

Materials And Methods: In this prospective observational study, we enrolled critically ill adult patients that were emergently admitted to an ICU. We assessed psychiatric symptoms and disability affecting ADL at three and twelve months after ICU discharge.

Sex Differences in Salivary Oxytocin and Cortisol Concentration Changes during Cooking in a Small Group.

Oxytocin (OT), a neuropeptide, has positive effects on social and emotional processes during group activities. Because cooking is an integrated process in the cognitive, physical, and socio-emotional areas, cooking in a group is reported to improve emotion and cognition. However, evidence for efficacy in group cooking has not been well established at the biological level.

Sensitive and fast optical imaging is needed for scientific instruments, machine vision, and biomedical diagnostics. Many of the fundamental challenges are addressed with time stretch imaging, which has been used for ultrafast continuous imaging for a diverse range of applications, such as biomarker-free cell classification, the monitoring of laser ablation, and the inspection of flat panel displays. With frame rates exceeding a million scans per second, the firehose of data generated by the time stretch camera requires optical data compression.

Discovery of WQ-3810: Design, synthesis, and evaluation of 7-(3-alkylaminoazetidin-1-yl)fluoro-quinolones as orally active antibacterial agents.

Novel 7-(3-alkylaminoazetidin-1-yl)fluoroquinolones were designed, synthesized, and evaluated for their antibacterial activities and oral absorption rates. Against Gram-negative bacteria, 10a-e, which have various alkyl groups containing different numbers of carbon atoms (C0-C3) at the C-7 alkylaminoazetidine position, showed potent and similar antibacterial activities, whereas the activity of 10f (C4, t-Bu) was significantly lower than those of 10a-e. Conversely, the oral absorption rates of 10a-e in rats increased depending on the number of carbon atoms in the alkyl groups; 10d (C3, n-Pr) and 10e (C3, i-Pr) had high oral absorption rates (>90% at 10 mg/kg).

Deletion of chromosome arm 15q in a case of minimally differentiated hypoplastic AML-M0.

Deletion of the long arm of chromosome 15 is known as a rare but recurrent chromosomal abnormality in myeloid malignancies. We report a novel case of minimally differentiated hypoplastic acute myeloid leukemia (AML M0) in a patient who initially had a normal karyotype, but clonal interstitial deletion of chromosome 15, del(15)(q11.2q22), coincided with increment of leukemic cells a year later.

Calyculin A retraction of mature megakaryocytes proplatelets from embryonic stem cells.

Platelets are produced by megakaryocytes (MKs) through proplatelet formation (PPF), or cytoplasmic extensions, in vitro. Through the use of video-enhanced light microscopy, as well as localization of cytoskeletal proteins by confocal microscopy, the reaction of fully mature MK proplatelets, derived from murine embryonic stem cells, to various agents was studied. Calyculin A (protein phosphatase 1/2A inhibitor) treatment induced proplatelet retraction.

Inhibition by Rho-kinase and protein kinase C of myosin phosphatase is involved in thrombin-induced shape change of megakaryocytic leukemia cell line UT-7/TPO.

Thrombin induced a shape change of UT-7/TPO, a thrombopoietin-dependent human megakaryocytic cell line. Expression of myosin light chain (MLC) kinase was negligible in UT-7/TPO cells, while Rho-kinase and protein kinase C (PKC) were detected. Thrombin stimulated both monophosphorylation at Ser19 and diphosphorylation at Thr18 and Ser19 of 20 kDa MLC, as well as phosphorylation of myosin-binding subunit (MBS) and PKC-potentiated inhibitory phosphoprotein of myosin phosphatase (CPI).

New findings on the structure-phototoxicity relationship and photostability of fluoroquinolones with various substituents at position 1.

The present study examined the phototoxicities of a series of 7-(3-aminopyrrolidinyl) quinolones containing various substituents at position 1 (in which the substituent at R8 is a hydrogen or a halogen) by use of a mouse model. For the 7-(3-aminopyrrolidinyl) quinolones with a halogen atom at position 8, well-known substituent groups such as a cyclopropyl, an ethyl, or a difluorophenyl at position 1 were found to be responsible for severe phototoxicity. However, when an aminodifluorophenyl or an isoxazolyl group was placed at position 1, even 8-halogeno quinolones were found to be mildly phototoxic.

Pharmacologic platelet anesthesia by glycoprotein IIb/IIIa complex antagonist and argatroban during in vitro extracorporeal circulation.

Objective: Contact between blood and the synthetic surfaces of a cardiopulmonary bypass circuit leads to platelet activation, and resultant platelet dysfunction contributes to postoperative bleeding. We compared the effects of various platelet inhibitors on preservation of platelet function during simulated cardiopulmonary bypass circulation.

Methods: Fresh human blood was recirculated in an in vitro cardiopulmonary bypass model circuit.

A novel antibacterial 8-chloroquinolone with a distorted orientation of the N1-(5-amino-2,4-difluorophenyl) group.

Fluoroquinolones represent a major class of antibacterial agents with great therapeutic potential. In this study, we designed m-aminophenyl groups as novel N-1 substituents of naphthyridones and quinolones. Among newly synthesized compounds, 7-(3-aminoazetidin-1-yl)-1-(5-amino-2,4-difluorophenyl)-8-chloro-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (4) has extremely potent antibacterial activities against Gram (+) as well as Gram (-) bacteria.

A 66-year-old man who suffered from diabetes mellitus and pancreatic carcinoma presented with aggressive progression of consciousness disturbance and high fever. The laboratory findings disclosed marked thrombocytopenia, hypercalcemia, and elevated serum PTH-related peptide.

[Analysis on deformity of disk associated with internal derangement of TMJ].

Internal derangement of temporomandibular joint has been studied mainly arthrographically about disk position, but it was reported that morphologic alterations and histo-chemical changes of disk were frequently observed in joints with internal derangement. The aim of this investigation was to study the relationship between deformity of disk and the kind of internal derangement of TMJ (anterior disk displacement with or without reduction). We analysed arthrographically the configuration of anterior displaced disk according to the criteria of Westesson.

Recurrence of 49-base decamers, nonomers, and octamers within mouse C mu gene of Ig heavy chain and its primordial building block.

Within the published 2,168-base-long mouse C mu gene of Ig heavy chain consisting of four coding and four noncoding segments, 2 base decamers, 8 nonomers, and 39 octamers recurred. Recurring base heptamers (about 100) and hexamers (about 350) were simply too numerous to merit individual identification. In spite of extensive overlaps between these recurring base decamers to hexamers, they occupied nearly the entire length of mouse Ig C mu gene.
