Identification and characterization of the CRK gene family in the wheat genome and analysis of their expression profile in response to high temperature-induced male sterility.

Cysteine-rich receptor-like kinases (CRKs) play many important roles during plant development, including defense responses under both biotic and abiotic stress, reactive oxygen species (ROS) homeostasis, callose deposition and programmed cell death (PCD). However, there are few studies on the involvement of the CRK family in male sterility due to heat stress in wheat ( L.).

Down-Regulation of Mitochondrial Metabolism after Tendon Release Primes Lipid Accumulation in Rotator Cuff Muscle.

Atrophy and fat accumulation are debilitating aspects of muscle diseases and are rarely prevented. Using a vertical approach combining anatomic techniques with omics methodology in a tenotomy-induced sheep model of rotator cuff disease, we tested whether mitochondrial dysfunction is implicated in muscle wasting and perturbed lipid metabolism, speculating that both can be prevented by the stimulation of β-oxidation with l-carnitine. The infraspinatus muscle lost 22% of its volume over the first 6 weeks after tenotomy before the area-percentage of lipid increased from 8% to 18% at week 16.

Analysis of the equine "cumulome" reveals major metabolic aberrations after maturation in vitro.

Background: Maturation of oocytes under in vitro conditions (IVM) results in impaired developmental competence compared to oocytes matured in vivo. As oocytes are closely coupled to their cumulus complex, elucidating aberrations in cumulus metabolism in vitro is important to bridge the gap towards more physiological maturation conditions. The aim of this study was to analyze the equine "cumulome" in a novel combination of proteomic (nano-HPLC MS/MS) and metabolomic (UPLC-nanoESI-MS) profiling of single cumulus complexes of metaphase II oocytes matured either in vivo (n = 8) or in vitro (n = 7).

Malva Sylvestris Attenuates Cognitive Deficits in a Repetitive Mild Traumatic Brain Injury Rat Model by Reducing Neuronal Degeneration and Astrocytosis in the Hippocampus.

BACKGROUND The aim of our study was to evaluate the effect of Malva sylvestris (MS) on cognitive dysfunction in a repetitive mild traumatic brain injury (MTBI). MATERIAL AND METHODS MTBI was induced in all the study animals by hitting a metallic pendulum near the parietal-occipital area of the skull three times a day for ten days. Animals were treated with MS (250 mg/kg and 500 mg/kg) intragastrically per day for seven consecutive days.

Intestinal SIRT3 overexpression in mice improves whole body glucose homeostasis independent of body weight.

Objective: Intestinal metabolism might play a greater role in regulating whole body metabolism than previously believed. We aimed to enhance enterocyte metabolism in mice and investigate if it plays a role in diet-induced obesity (DIO) and its comorbidities.

Methods: Using the cre-loxP system, we overexpressed the mitochondrial NAD dependent protein deacetylase SIRT3 in enterocytes of mice (iSIRT3 mice).

Genomic and lipidomic actions of nandrolone on detached rotator cuff muscle in sheep.

Reversal of fatty infiltration of pennate rotator cuff muscle after tendon release is hitherto impossible. The administration of nandrolone starting at the time of tendon release prevents the increase in fat content, but does not revert established fatty infiltration. We hypothesised that tendon release and myotendinous retraction cause alterations in lipid related gene expression leading to fatty muscle infiltration, which can be suppressed by nandrolone through its genomic actions if applied immediately after tendon release.

Risk assessment of ischemic stroke associated pneumonia.

Background: Cerebral stroke is a disease with a high disability rate and a high fatality rate. This study was undertaken to assess the risk of stroke associated pneumonia (SAP) in patients with ischemic stroke using A2DS2 score.

Methods: Altogether 1 279 patients with ischemic stroke who were treated in our department from 2009 to 2011 were retrospectively analyzed with A2DS2 score.

Psychological resilience moderates the impact of social support on loneliness of "left-behind" children.

This study examined the moderator effect of psychological resilience on the relationship between social support and loneliness of the "left-behind" children. A total of 200 left-behind girls and 214 left-behind boys completed the measures of psychological resilience, social support, and loneliness. Hierarchical regression analysis showed that psychological resilience moderated the association between social support and loneliness.

Self-esteem mediates the effect of the parent-adolescent relationship on depression.

There is a trend of rapid growth in both the level and occurrence of depression when people reach adolescence. The present study aimed to investigate the impact of the parent-adolescent relationship on depression in adolescents, and mainly focused on the confirmation of the mediator role of self-esteem. A total of 364 senior middle school students accomplished the Parent-Adolescent Relationship Scale, Rosenberg Self-Esteem Scale, and Zung Self-Rating Depression Scale.

[Screening of key genes and inflammatory signalling pathway involved in the pathogenesis of HLA-B27-associated acute anterior uveitis by gene expression microarray].

Objective: To investigate the genes and signalling pathways located upstream of the inflammatory processes in human leukocyte antigen (HLA)-B27-associated acute anterior uveitis by gene expression microarray.

Methods: Experimental study. HLA-B27-positive and-negative monocytes isolated from human peripheral blood were stimulated with Vibrio cholera lipopolysaccharide (LPS).

Interaction of HIF and USF signaling pathways in human genes flanked by hypoxia-response elements and E-box palindromes.

Rampant activity of the hypoxia-inducible factor (HIF)-1 in cancer is frequently associated with the malignant progression into a harder-to-treat, increasingly aggressive phenotype. Clearly, anti-HIF strategies in cancer cells are of considerable clinical interest. One way to fine-tune, or inhibit, HIF's transcriptional outflow independently of hydroxylase activities could be through competing transcription factors.

Endogenous myoglobin in breast cancer is hypoxia-inducible by alternative transcription and functions to impair mitochondrial activity: a role in tumor suppression?

Recently, immunohistochemical analysis of myoglobin (MB) in human breast cancer specimens has revealed a surprisingly widespread expression of MB in this nonmuscle context. The positive correlation with hypoxia-inducible factor 2α (HIF-2α) and carbonic anhydrase IX suggested that oxygen regulates myoglobin expression in breast carcinomas. Here, we report that MB mRNA and protein levels are robustly induced by prolonged hypoxia in breast cancer cell lines, in part via HIF-1/2-dependent transactivation.

Enhancement of axonal regeneration of retinal ganglion cells in adult rats by etomidate: involvement of protein kinase C.

Purpose: To investigate the effect of etomidate (ET) on axonal regeneration of retinal ganglion cells (RGCs) in adult rats.

Methods: The optic nerve was transected intraorbitally at 1 mm from the optic disc, and an autologous peripheral nerve was transplanted onto the ocular ON stump in adult rats. Then the animals were treated with ET, Gö6976, ET combined with Gö6976, phorbol-12-myristate-13-acetate (PMA), or ET combined with PMA.

[Anatomy of the sphenoidal sinus in transsphenoidal approach through a single nostril].

Objective: To study the anatomy of the sphenoid sinus for safe pituitary adenoma resection via transsphenoidal approach through a single nostril.

Methods: Eight fresh adult cadavers and the magnetic resonance images (MRI) of the sphenoidal sinus of 5 adults were observed. In anteroposterior axes, the root of the nasal columella was defined as the point O, the inferior border of the sphenoidal sinus anterior wall as point B, the superior border of the spheniodal sinus anterior wall as point C, and the midpoint of the sellar floor as point D.
