The amino acid cysteine plays a major role in plant response to abiotic stress by being the donor of elemental sulfur for the sulfuration of the molybdenum cofactor, otherwise the last step of ABA biosynthesis, the oxidation of abscisic aldehyde, is inactivated. Additionally, cysteine serves as a precursor for the biosynthesis of glutathione, the reactive oxygen species scavenger essential for redox status homeostasis during stress. Cysteine is generated by the sulfate reductive pathway where sulfite oxidase (SO; EC 1...

AIM: This pilot study aimed to examine the difference in energy and protein intake of the midday meal in two different eating environments-the communal dining room and patient bedside-and to obtain feedback on patient preference at each location. METHODS: Elderly patients in two rehabilitation wards were observed consuming the midday meal on two consecutive days: day 1 in the dining room and day 2 at the bedside. The patients' intake was recorded by a visual 5-point assessment scale and analysed for protein and energy content using the hospital food services nutrient analysis of the menu...

The effects of β adrenergic receptors (β-ARs) and p38 mitogen-activated protein kinases (MAPK) pathways on cardiosphere-derived cells (CDCs) are largely unknown. This study aimed to investigate the roles of β-ARs and p38MAPK pathways on the proliferation, apoptosis and differentiation capacity of CDCs. The CDCs were treated with β1-AR blocker (Met group), β2-AR antagonist (ICI group) and p38MAPK inhibitor (SB group), nonselective β-AR blocker (PRO group), and β-AR agonist (ISO group). The viability, apoptotic rate and differentiation status of CDCs were determined by MST-1 assay, flow cytometery, and Western blot, respectively...

BACKGROUND: Whether surgical resection for recurrent biliary tract carcinoma (BTC) prolongs survival and the patients who are most likely to benefit from such treatment remain unclear. METHODS: Among 251 patients with recurrences after the initial resection of BTC, a total of 21 patients (8.4%) underwent surgical resection for the recurrence, with a zero mortality rate. The clinicopathological features of these patients were compared with those of patients who did not undergo surgery...

The interaction between the renal water channel aquaporin-2 (AQP2) and the lysosomal trafficking regulator-interacting protein LIP5 targets AQP2 to multivesicular bodies and facilitates lysosomal degradation. This interaction is part of a process which controls AQP2 apical membrane abundance in a vasopressin-dependent manner, allowing for urine volume adjustment. Vasopressin regulates phosphorylation at four sites within the AQP2 C-terminus (S256, S261, S264, T269), of which S256 is crucial and sufficient for AQP2 translocation from storage vesicles to the apical membrane...

Drum corps color guard experts spend years developing skills in spinning rifles, sabers, and flags. Their expertise provides a unique window into factors that govern sensitivity to the speed of rotational and radial motion. Prior neurophysiological research demonstrates that rotational and radial motion register in the Medial Superior Temporal (MST) region of the primate visual system. To the extent that shared neural events govern rotational and radial speed sensitivity, one would expect expertise on either task to transfer to the other...

Enhancement of the systemic distribution of a chemical control agent by exploiting the normal movement of a solute through a plant's vascular system will surely increase its efficacy, and thereby allows for a reduction in both the volume and frequency of their application. Foliar uptake and phloem transport of N-[3-cyano-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-[(trifluoromethyl)sulfinyl]-1H-pyrazol-5-yl]-1-(β-D-glucopyranosyl)-1H-1,2,3-triazole-4-methanamine (GTF), a glucose-fipronil conjugate, involved a carrier-mediated mechanism in Ricinus communis by utilizing castor bean monosaccharide transporters...

BACKGROUND AND OBJECTIVE: Postural muscle responses are often impaired after stroke. We aimed to identify the contribution of deficits in very early postural responses to poorer reactive balance capacity, with a particular focus on reactive stepping as a key strategy for avoiding falls. METHODS: A total of 34 chronic stroke survivors and 17 controls were subjected to translational balance perturbations in 4 directions. We identified the highest perturbation intensity that could be recovered without stepping (single stepping threshold [SST]) and with maximally 1 step (multiple stepping threshold [MST])...

BACKGROUND: For patients with melanoma metastases in the pelvic and groin regions, the median survival time (MST) was 8 mo with old treatments, whereas today is approximately 20 mo with new target therapy and novel immunotherapy. Unfortunately, approximately 30% of patients are nonresponsive to these new drugs. MATERIALS AND METHODS: Thirty-six patients, previously progressing after standard treatments, collectively received 146 melphalan (30 mg/m(2)) hypoxic pelvic perfusions with hemofiltration, in association with palliative excision in most cases...

The recommended chemotherapy regimens for pancreatic cancer include the combination of 5-fluorouracil/leucovorin, oxaliplatin and irinotecan (FOLFIRINOX), nab-paclitaxel (nab-PTX) plus gemcitabine (GEM), GEM alone and tegafur/gimeracil/oteracil potassium (S-1) alone. Although the cost-effectiveness of metastatic pancreatic cancer chemotherapies has been extensively investigated, to the best of our knowledge, no study has specifically compared the cost-effectiveness among FOLFIRINOX, nab-PTX + GEM, GEM and S-1 regimens to date...

Calum MacKellar
In the discussions leading up to the enactment of the UK Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015, it was repeatedly emphasised, by many commentators, that maternal spindle transfer (MST) and pronuclear transfer (PNT) did not give rise to children who could be considered as having three or more parents. This was because it was argued that only the genetic material found in the chromosomes should be considered as the determining factor for the formation of parent-child relationships and the resulting kinship identities...

OBJECTIVE: Therapist adherence is a quality indicator in routine clinical care when evaluating the success of the implementation of an intervention. The current study investigated whether therapist adherence mediates the association between therapist, team, and country-wide experience (i.e. number of years since implementation in the country) on the one hand, and treatment outcome on the other hand. We replicated and extended a study by Löfholm et al. (2014). METHOD: Data over a 10-year period were obtained from 4290 adolescents (12-17 years) with antisocial or delinquent problem behavior, who were treated with Multisystemic Therapy (MST) by 222 therapists, working in 27 different teams in the Netherlands...

Sexual trauma survivors are reluctant to disclose such a history due to stigma. This is likely the case when estimating the prevalence of sexual trauma experienced in the military. The Veterans Health Administration has a program by which all former US military service members (Veterans) are screened for military sexual trauma (MST) using a questionnaire. Administrative data on MST screens and a change of status from an initial negative answer to positive and natural language processing (NLP) on electronic medical notes to extract concepts related to MST were used to refine initial estimates of MST among a random sample of 20,000 Veterans...

The aim of the present study was to expound on the interactions between the mitogen-activated protein kinase (MAPK) and Hippo pathway members, and to further elucidate the molecular mechanisms of melanoma tumorigenesis. Four melanoma cell lines (C32, HS695T, SK-MEL-28 and A375) were used in the present study. Western blotting was used to assess the expression levels of the MAPK and Hippo pathway effector proteins: rapidly accelerated fibrosarcoma-1 proto-oncogene, serine/threonine kinase (RAF-1); serine/threonine kinase 3 (STK3; also known as MST-2); yes-associated protein (YAP); and tafazzin (TAZ)...

Using the Mnemonic Similarity Task (MST), we have demonstrated an age-related impairment in lure discrimination, or the ability to recognize an item as distinct from one that was similar, but not identical to one viewed earlier. A growing body of evidence links these behavioral changes to age-related alterations in the hippocampus. In this study, we sought to evaluate a novel version of this task, utilizing scenes that might emphasize the role of the hippocampus in contextual and spatial processing. In addition, we investigated whether, by utilizing two stimulus classes (scenes and objects), we could also interrogate the roles of the PRC and PHC in aging...

We report the use of microfluidic surface titrations (MSTs) for studying electroactive self-assembled monolayers (eSAMs) and other thin films. The technique of MST utilizes a microfluidic generation-collection dual channel electrode (DCE) configuration to quantify the charge associated with electroactive thin films that might or might not be in direct contact with an electrode surface. This technique allows for quantitative measurement of surface coverages, Γ, as low as 30 pmol cm(-2) for electrodeposited Cu thin films...

INTRODUCTION: This study aims to identify novel quantitative EEG measures associated with mindfulness meditation. As there is some evidence that meditation is associated with higher integration of brain networks, we focused on EEG measures of network integration. METHODS: Sixteen novice meditators and sixteen experienced meditators participated in the study. Novice meditators performed a basic meditation practice that supported effortless awareness, which is an important quality of experience related to mindfulness practices, while their EEG was recorded...

AIM: Sorafenib is the recommended standard of care for advanced hepatocellular carcinoma (HCC) patients. However, hepatic arterial infusion chemotherapy (HAIC) is a treatment option in Asia. We recently developed the 'assessment for continuous treatment with HAIC' (ACTH) score to guide decision-making for continuous HAIC treatment. The purpose of this study was to validate the utility of the ACTH score in a dedicated cohort. METHODS: One-hundred and thirty-one advanced HCC patients were enrolled in this study (90 in the training group and 41 in the validation group)...

High intensity (resistance exercise) training (HIT) defined as a "single set resistance exercise to muscular failure" is an efficient exercise method that allows people with low time budgets to realize an adequate training stimulus. Although there is an ongoing discussion, recent meta-analysis suggests the significant superiority of multiple set (MST) methods for body composition and strength parameters. The aim of this study is to determine whether additional protein supplementation may increase the effect of a HIT-protocol on body composition and strength to an equal MST-level...
