Double-stranded RNA targeting fungal ergosterol biosynthesis pathway controls Botrytis cinerea and postharvest grey mould.

Pathogenic fungi cause major postharvest losses. During storage and ripening, fruit becomes highly susceptible to fungi that cause postharvest disease. Fungicides are effective treatments to limit disease.

Pathways to defense metabolites and evading fruit bitterness in genus Solanum evolved through 2-oxoglutarate-dependent dioxygenases.

The genus Solanum comprises three food crops (potato, tomato, and eggplant), which are consumed on daily basis worldwide and also producers of notorious anti-nutritional steroidal glycoalkaloids (SGAs). Hydroxylated SGAs (i.e.

Plant serpin protease inhibitors: specificity and duality of function.

The serpins are a family of structurally conserved protease inhibitors found in all animal and plant kingdoms. After interaction with their cognate substrate(s), their native energetically stressed state is relaxed by hydrolysis, resulting in a semi-stable covalent bond that disables the protease. The inherent flexible serpin structure supports additional non-inhibitory functions.

[Stabilometric markers of biological age.].

The aim of this study was to find stabilometric parameters, the values of which correlate with chronological age. The results of the standard stabilometric test with open and closed eyes, which obtained during the examination of 87 people aged from 20 to 70 years, were considered. Basic, vector and frequency indicators of 618 tests (334 with open eyes and 284 with closed eyes) were analyzed.

Assessing fracture risk in early stage breast cancer patients treated with aromatase-inhibitors: An enhanced screening approach incorporating trabecular bone score.

Introduction: Aromatase-inhibitors (AIs) are commonly used for treatment of patients with hormone-receptor positive breast carcinoma, and are known to induce bone density loss and increase the risk of fractures. The current standard-of-care screening tool for fracture risk is bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA). The fracture risk assessment tool (FRAX®) may be used in conjunction with BMD to identify additional osteopenic patients at risk of fracture who may benefit from a bone-modifying agent (BMA).

Recurrent Kidney Stone Episodes Leading to a Diagnosis of Occult Acromegaly.

The association between nephrolithiasis and acromegaly has been previously described. Although the mechanism has been established, the urological literature sparsely discusses clinically suspecting that patients with recurrent nephrolithiasis could have acromegaly and subsequently referring them for accurate diagnosis and treatment. We present a case of occult acromegaly secondary to a pituitary tumor discovered 20 years after the patient's first stone episode.

Insights on accelerated skeletal repair in Cushing's disease.

Cushing's disease with prolonged exposure to high circulating levels of glucocorticoids is associated with deterioration of the structural integrity of bone, resulting in increased skeletal fragility and fractures. The mechanism of bone repair following successful surgical treatment is poorly understood. A 34-year-old man presented with a tibial fracture and severely low BMD, elevated AM serum cortisol, ACTH, and 24 h urinary free cortisol, which did not suppress with 2 days of high dose dexamethasone.

[Clinical significance of pointed medicamental and non-medicamental therapy in the staged combined treatment of radiculopathies].

We analysed the results of the treatment of 4205 patients with different forms of vertebrogenic radiculopathy. They suggest the efficacy of differential application of graduated medicamental therapy, reflexo- and physiotherapy depending on the period of clinical course of the disease.

Set-point control of RD21 protease activity by AtSerpin1 controls cell death in Arabidopsis.

Programmed cell death (PCD) in plants plays a key role in defense response and is promoted by the release of compartmentalized proteases to the cytoplasm. Yet the exact identity and control of these proteases is poorly understood. Serpins are an important group of proteins that uniquely curb the activity of proteases by irreversible inhibition; however, their role in plants remains obscure.

A novel approach for improved tractography and quantitative analysis of probabilistic fibre tracking curves.

This paper presents a novel approach for improved diffusion tensor fibre tractography, aiming to tackle a number of the limitations of current fibre tracking algorithms, and describes a quantitative analysis tool for probabilistic tracking algorithms. We consider the sampled random paths generated by a probabilistic tractography algorithm from a seed point as a set of curves, and develop a statistical framework for analysing the curve-set geometrically that finds the average curve and dispersion measures of the curve-set statistically. This study is motivated firstly by the goal of developing a robust fibre tracking algorithm, combining the power of both deterministic and probabilistic tracking methods using average curves.

A novel white matter fibre tracking algorithm using probabilistic tractography and average curves.

This paper presents a novel white matter fibre tractography approach using average curves of probabilistic fibre tracking measures. We compute "representative" curves from the original probabilistic curve-set using two different averaging methods. These typical curves overcome a number of the limitations of deterministic and probabilistic approaches.

[Spondylogenic visceropathies].

A group of 830 patients with spondylogenic visceropathies was divided into three with clinical symptoms of bronchial (n = 80), cardiac (n = 530), and abdominal (n = 220) vertebral syndromes. Their clinical features, differential diagnosis and methods of treatment are described.

Arabidopsis AtSerpin1, crystal structure and in vivo interaction with its target protease RESPONSIVE TO DESICCATION-21 (RD21).

In animals, protease inhibitors of the serpin family are associated with many physiological processes, including blood coagulation and innate immunity. Serpins feature a reactive center loop (RCL), which displays a protease target sequence as a bait. RCL cleavage results in an irreversible, covalent serpin-protease complex.

Ammonium secretion by Colletotrichum coccodes activates host NADPH oxidase activity enhancing host cell death and fungal virulence in tomato fruits.

Colletotrichum pathogens of fruit and leaves are known ammonium secretors. Here, we show that Colletotrichum coccodes virulence, as measured by tomato (Solanum lycopersicum cv. Motelle) fruit tissue necrosis, correlates with the amount of ammonium secreted.

Functional-genomics-based identification of genes that regulate Arabidopsis responses to multiple abiotic stresses.

Abiotic stresses are a primary cause of crop loss worldwide. The convergence of stress signalling pathways to a common set of transcription factors suggests the existence of upstream regulatory genes that control plant responses to multiple abiotic stresses. To identify such genes, data from published Arabidopsis thaliana abiotic stress microarray analyses were combined with our presented global analysis of early heat stress-responsive gene expression, in a relational database.

[The main directions for improving the medical supply specialists training in conditions of pharmaceutical education system reformation in our country].

The beginning of Russian pharmaceutical education reform requires the new approaches to organization of medical supply specialists' training. The specialized training of medical supply managerial staff for the Armed Forces is conducted in the department of military medical supply and pharmaceutics in the Kirov Military Medical Academy. The completion of pre-graduation training of such specialists is conducted in the Tomsk military medical institute.

Sulfite oxidase protects plants against sulfur dioxide toxicity.

The gaseous pollutant SO(2) readily reacts with water to form sulfite that impacts deleteriously on animal and plant health. By modulating the level of sulfite oxidase (SO) that catalyzes the transformation of sulfites to the non-toxic sulfate, we show that Arabidopsis and tomato plants can be rendered resistant or susceptible to SO(2)/sulfite. Plants in which sulfite oxidase expression was abrogated by RNA interference (RNAi) accumulated relatively less sulfate after SO(2) application and showed enhanced induction of senescence and wounding-associated transcripts, leaf necrosis and chlorophyll bleaching.

[Some features of coronary artery disease combined with vertebrogenic thoracoalgias].

The subjects of the study were 4223 patients who were examined for heartache between 1998 and 2005. The patients were divided into three groups. Group I were 617 patients with isolated vertebrogenous cardiomyalgia; group II included 1238 patients with coronary heart disease; group III consisted of 2368 who suffered from both conditions.

Diverse subcellular locations of cryptogein-induced reactive oxygen species production in tobacco Bright Yellow-2 cells.

Reactive oxygen species (ROS) play a crucial role in many cellular responses and signaling pathways, including the oxidative burst defense response to pathogens. We have examined very early events in cryptogein-induced ROS production in tobacco (Nicotiana tabacum) Bright Yellow-2 suspension cells. Using Amplex Red and Amplex Ultra Red reagents, which report real-time H2O2 accumulation in cell populations, we show that the internal signal for H2O2 develops more rapidly than the external apoplastic signal.

The global nitrogen regulator, FNR1, regulates fungal nutrition-genes and fitness during Fusarium oxysporum pathogenesis.

SUMMARY Fusarium oxysporum is a soil-borne pathogen that infects plants through the roots and uses the vascular system for host ingress. Specialized for this route of infection, F. oxysporum is able to adapt to the scarce nutrient environment in the xylem vessels.

Rapid transcriptome changes induced by cytosolic Ca2+ transients reveal ABRE-related sequences as Ca2+-responsive cis elements in Arabidopsis.

The regulation of gene expression by cellular calcium is crucial for plant defense against biotic and abiotic stresses. However, the number of genes known to respond to specific transient calcium signals is limited, and as yet there is no definition of a calcium-responsive cis element in plants. Here, we generated specific cytosolic calcium transients in intact Arabidopsis thaliana seedlings and linked them to early transcriptome changes, followed by bioinformatic analysis of the responsive genes.

Nitrogen-responsive genes are differentially regulated in planta during Fusarium oxyspsorum f. sp. lycopersici infection.

SUMMARY Nitrogen is an essential growth component whose availability will limit microbial spread, and as such it serves as a key control point in dictating an organism's adaptation to various environments. Little is known about fungal nutrition in planta. To enhance our understanding of this process we examined the transcriptional adaptation of Fusarium oxysporum f.
