A combinatorial TIR1/AFB–Aux/IAA co-receptor system for differential sensing of auxin

The plant hormone auxin regulates virtually every aspect of plant growth and development. Auxin acts by binding the F-box protein transport inhibitor response 1 (TIR1) and promotes the degradation of the AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) transcriptional repressors. Here we show that efficient auxin binding requires assembly of an auxin co-receptor complex consisting of TIR1 and an Aux/IAA protein. Heterologous experiments in yeast and quantitative IAA binding assays using purified proteins showed that different combinations of TIR1 and Aux/IAA proteins form co-receptor complexes with a wide range of auxin-binding affinities. Auxin affinity seems to be largely determined by the Aux/IAA. As there are 6 TIR1/AUXIN SIGNALING F-BOX proteins (AFBs) and 29 Aux/IAA proteins in Arabidopsis thaliana, combinatorial interactions may result in many co-receptors with distinct auxin-sensing properties. We also demonstrate that the AFB5–Aux/IAA co-receptor selectively binds the auxinic herbicide picloram. This co-receptor system broadens the effective concentration range of the hormone and may contribute to the complexity of auxin response

Application of Onset Theory to Onset of Transverse Cracking in Fabric Composites

A paper presented at ICCM-19 included a methodology for application of Onset Theory to the prediction of microcracking in the transverse plies of orthogonal [0/90] fabric laminates. This paper applies the methodology to predict damage locations and laminate strains for failure of plain weave fabric specimens manufactured from two material systems – HTS40/RTM6 and T300/CYCOM970. The laminate strains are first dehomogenised to define local strains in the tow architecture of the fabric. This is achieved using meso-mechanical unit cell analysis in which the resin and tows are modelled as continua. For a selection of predefined critical locations in the tow bundles, the strains are further dehomogenised using an identical procedure as the one defined for the uni-directional specimens in the previous applications. The influence of matrix plasticity and temperature dependent mechanical and thermal properties of the RTM6 resin are applied in the dehomogenisation procedure. The Onset theory predictions for damage locations were compared to those obtained from microscopic surveys of partially failed plain weave fabric specimens

Mechanical homeostasis regulating adipose tissue volume

<p>Abstract</p> <p>Background</p> <p>The total body adipose tissue volume is regulated by hormonal, nutritional, paracrine, neuronal and genetic control signals, as well as components of cell-cell or cell-matrix interactions. There are no known locally acting homeostatic mechanisms by which growing adipose tissue might adapt its volume.</p> <p>Presentation of the hypothesis</p> <p>Mechanosensitivity has been demonstrated by mesenchymal cells in tissue culture. Adipocyte differentiation has been shown to be inhibited by stretching in vitro, and a pathway for the response has been elucidated. In humans, intermittent stretching of skin for reconstructional purposes leads to thinning of adipose tissue and thickening of epidermis – findings matching those observed in vitro in response to mechanical stimuli. Furthermore, protracted suspension of one leg increases the intermuscular adipose tissue volume of the limb. These findings may indicate a local homeostatic adipose tissue volume-regulating mechanism based on movement-induced reduction of adipocyte differentiation. This function might, during evolution, have been of importance in confined spaces, where overgrowth of adipose tissue could lead to functional disturbance, as for instance in the turtle. In humans, adipose tissue near muscle might in particular be affected, for instance intermuscularly, extraperitoneally and epicardially. Mechanical homeostasis might also contribute to protracted maintainment of soft tissue shape in the face and neck region.</p> <p>Testing of the hypothesis</p> <p>Assessment of messenger RNA-expression of human adipocytes following activity in adjacent muscle is planned, and study of biochemical and volumetric adipose tissue changes in man are proposed.</p> <p>Implications of the hypothesis</p> <p>The interpretation of metabolic disturbances by means of adipose tissue might be influenced. Possible applications in the head and neck were discussed.</p

Safety, Tolerability, and Efficacy of Insulin Aspart in People with Type 2 Diabetes, as Biphasic Insulin Aspart or with Basal Insulin: Findings from the Multinational, Non-Interventional A1chieve Study

INTRODUCTION: The aim of the study was to investigate the clinical safety and effectiveness of starting insulin aspart (aspart) therapy in people with type 2 diabetes mellitus (T2DM) as a sub-analysis of the multinational, non-interventional A1chieve study. METHODS: Insulin-naïve and insulin-experienced people with T2DM in routine clinical care starting aspart alone at baseline and continuing aspart alone, changing to biphasic insulin aspart 30 (aspart premix) or adding a basal insulin by study end, were included. Safety, tolerability, and efficacy were evaluated over 24 weeks. RESULTS: Overall, 3,898 people started aspart at baseline. Of the 3,313 with 24-week data, 1,545 (46.6%) continued with aspart, 1,379 (41.6%) switched to aspart premix, and 214 (6.5%) added basal insulin, while the remainder switched to other regimens. No serious adverse drug reactions were reported. The proportion of participants reporting hypoglycemia decreased from baseline to week 24 in the aspart alone group (11.2% versus 4.1%, p < 0.001) and in the aspart + basal insulin group (13.1% versus 7.5%, p = 0.040), and was 3.7% at week 24 in the aspart premix group. The mean HbA1c decreased from baseline to week 24 (aspart: −2.1 ± 2.0% [−23 ± 22 mmol/mol], aspart premix: −2.3 ± 1.7% [−25 ± 19 mmol/mol], aspart + basal insulin: −2.0 ± 2.1% [−22 ± 23 mmol/mol]; p < 0.001). CONCLUSION: Insulin aspart therapy was well tolerated and was associated with improved glucose control over 24 weeks in people with T2DM.

‘G’ followed by ‘H’-gout follows homoeopathy

Currently in modern medicine, it is seen that taking a uric acid reducing drug during an attack of gout actually prolongs the pain and discomfort. So, the learning is that one need not worry about high uric acid levels during an acute flair of gout. What actually someone needs is an anti-inflammatory that reduces the inflammation caused by the crystals of uric acid that build up in the joints when someone has gout. This anti-inflammatory drug is ‘colchicine’. Homoeopathy has been using the drug ‘colchicum autumnale’ for last 233 years since its discovery in 1790 by Dr. Samuel Hahnemann (1755-1843). It also uses its active principle ‘colchicine’ for the last 233 years. It is quite striking to see that the modern medicine is realizing the importance of ‘colchicine’ currently. The same ‘colchicine’ was advised to be used as an anti-inflammatory to reduce the markers like C-reactive protein, LDH, D-dimer and homocysteine. During the COVID-19 peak, again the homoeopathic Colchicine came to the rescue. The current article examines the use of homoeopathy in gout and uric acid problems and again at a larger issue with the protein metabolism and the kidney heath. Integration of homoeopathy at large scale will help the nation to protect its members from protein metabolism disorders, kidney health and gout as well

Evaluation of zinc oxide nanocomposites and L-ascorbic acid on meat quality during transport induced stress in birds of Sonali breed

The study assessed the efficacy of phytofabricated zinc oxide nanoparticles (CF-ZnONPs) and L-ascorbic acid in alleviating pre-slaughter transport induced stress in birds of Sonali breed (Cross bred of Rhode Island Red cocks and Fayoumi hens). A total of 120 birds were divided into four groups: negative control (T1) which were loaded in vehicle but not transported, Positive control (T2) birds were transported without any prior supplementation, T3 and T4 birds were transported with prior supplementation (a day before transportation) of CF-ZnONPs @100 µg/ml and L-ascorbic acid @82 µg/ml in drinking water. Results obtained observed significant reduction in live weight, meat colour and pH but increased drip loss percentage in T2 group. Significantly elevated H/L ratio was recorded in all transported groups. Increased cortisol and TSH levels and decreased thyroid hormones, Triiodothyronine and thyroxin (T3 and T4) levels were recorded in T2 group. However, supplementation with CF-ZnONPs and L-ascorbic acid notably reversed these adverse effects, restoring meat quality and other metabolic profiles. Notably, ascorbic acid exhibited greater efficacy, suggesting its superior role in mitigating transportation-induced stress. Overall, these findings highlight the importance of antioxidant supplementation in alleviating transport induced stress in birds

Emerging roles of ATF2 and the dynamic AP1 network in cancer

Cooperation among transcription factors is central for their ability to execute specific transcriptional programmes. The AP1 complex exemplifies a network of transcription factors that function in unison under normal circumstances and during the course of tumour development and progression. This Perspective summarizes our current understanding of the changes in members of the AP1 complex and the role of ATF2 as part of this complex in tumorigenesis.Fil: Lopez Bergami, Pablo Roberto.
