Wilt caused by Verticillium dahliae significantly reduces cotton yields, as host resistance in commercially cultivated Gossypium species is lacking. Understanding the molecular bases of disease resistance in non-commercial Gossypium species could galvanize the development of Verticillium wilt resistance in the cultivated species. Nucleotide binding site-leucine-rich repeat (NBS-LRR) proteins play a central role in plant defense against pathogens. In this study, we focused on the relationship between a locus enriched with eight NBS-LRR genes and Verticillium wilt resistance in G...

The young leaves of virescent mutants are yellowish and gradually turn green as the plants reach maturity. Understanding the genetic basis of virescent mutants can aid research of the regulatory mechanisms underlying chloroplast development and chlorophyll biosynthesis, as well as contribute to the application of virescent traits in crop breeding. In this study, fine mapping was employed, and a recessive gene (v 1) from a virescent mutant of Upland cotton was narrowed to an 84.1-Kb region containing ten candidate genes...

BACKGROUND: Cholecystectomy is a common operation, increasingly performed, in the USA, for "functional gall bladder disorder" (FGBD). Outcomes of these surgeries are uncertain. In planning a study of FGBD, we needed to define the best outcome measures. METHODS: We sought the opinions of patients (52 with FGBD and 100 with stones for comparison) coming to cholecystectomy. They were asked to respond in four ways about the minimum benefit they would count as "success...

The research work presented herein was undertaken with a view to develop, characterize and highlight modified cotton fabrics that acquire durable antibacterial activity in concomitant with high metal sorption capacity. The development is based on reacting cotton cellulose previously oxidized by sodium periodate-with 4 amino-1,2,4 triazole in presence and absence of silver nano particles (AgNPs). The idea behind the periodate pretreatment is to convert (via oxidative cleavge) the 2,3-vicinal diol of the anhydroglucose units of cotton into aldehyde groups...

H Y Lin, R P Dai
Transthyretin (TTR)-related familial amyloid polyneuropathy (FAP), which is caused by mutant TTR, is a rare but fatal autosomal dominant disease. TTR is synthesized by the liver (95%) , the choroid plexus of the brain and the retinal pigment epithelium. FAP leads to peripheral neuropathy, and the main ocular manifestations are vitreous opacity (yellowish cotton-like), secondary glaucoma and keratoconjunctivitis sicca. Liver transplantation has proven to be the most effective treatment for TTR-FAP. Nowadays, tafamidis is the only drug approved for TTR-FAP (early stage)...

OBJECTIVE: Traumatic endotheliopathy (EoT) is associated with glycocalyx breakdown and capillary leak resulting in the extravasation of proteins. We hypothesized that lower serum albumin levels are associated with EoT, poor outcomes, and can be used for early EoT screening in trauma patients. METHODS: We enrolled severely injured trauma patients with serum albumin levels available on admission. Syndecan-1 and soluble thrombomodulin were quantified from plasma by ELISA...

Compared with controls, treatment of the cultivation substrate for Volvariella volvacea with 0.02% NaAc at the "spraying water" stage increased the number of fruiting body primordia by 280, the mushroom yield by 16.25%, the number of fruiting bodies by 35.57%, and the biological efficiency by 16.28%. The average single mushroom weight increased by 19.33%, but there was no significant difference between treatments and controls. A correlation analysis revealed a significant (p < 0.05) positive correlation between the total yield and the number of fruiting bodies...

Calcium (Ca2+) is necessary for fiber cell development in cotton (Gossypium hirsutum), both as a cell wall structural component and for environmental signaling responses. It is also known that potassium (K+) plays a critical role in cotton fiber cell elongation. However, it is unclear whether Ca2+ integrates its activities with K+ to regulate fiber elongation. Here, we report the novel discovery that Ca2+ deficiency, when integrated with K+ signaling, promotes fiber elongation. Using inductively coupled plasma-mass spectrometry (ICP-MS), we determined dynamic profiles of the ionome in ovules and fibers at different developmental stages, and found that a high accumulation of macro-elements, but not Ca2+, was associated with longer fibers...

An index to predict hospital length of stay after liver transplantation could address unmet clinical needs. Length of stay is an important surrogate for hospital costs and efforts to limit stays can preserve our healthcare resources. Here, we devised a scoring system that predicts hospital length of stay following liver transplantation. We used univariate and multivariate analyses on 73,635 adult liver transplant recipient data and identified independent recipient and donor risk factors for prolonged hospital stay (> 30 days)...

Herbivore-induced terpenes have been reported to function as ecological signals in plant-insect interactions. Here we showed that insect-induced cotton volatile blends contained 16 terpenoid compounds with a relatively high level of linalool. The high diversity of terpene production is derived from a large terpene synthase (TPS) gene family. The TPS gene family of Gossypium hirsutum and G. raimondii consist of 46 and 41 members, respectively. Twelve TPS genes (GhTPS4-15) could be isolated and protein expression in E...

BACKGROUND: The burden of hearing loss is on the increase, especially in low-income countries such as South Africa. The need for urgent action to prevent ear and hearing problems is a priority, especially as in many cases permanent hearing loss is preventable. In South Africa, as in other developing countries, there is a limited number of hearing health professionals and audiological resources. The lack of hearing health services may impact the general public's awareness of hearing and hearing health...

Paolo Zardi, Klaus Wurst, Giulia Licini, Cristiano Zonta
Enantiomeric excess determination is crucial in many aspects of science ranging from synthesis to materials. Within this subject, the use of molecular sensors coupled with chiroptical techniques is a straightforward approach to the stereochemical analysis of chiral molecules, especially in terms of process immediacy and labor. Ste-reodynamic probes typically consist of racemic mixtures of rapidly interconverting enantiomeric conformers able to recognize a chiral analyte and greatly amplify its chiroptical readout...

Colloidal suspensions of anisotropic nanoparticles can spontaneously self-organize in liquid-crystalline phases beyond some concentration threshold. These phases often respond to electric and magnetic fields. At lower concentrations, usual isotropic liquids are observed but they can display very strong Kerr and Cotton-Mouton effects (i.e., field-induced particle orientation). For many examples of these colloidal suspensions, the solvent is water, which hinders most electro-optic applications. Here, for goethite (α-FeOOH) nanorod dispersions, we show that water can be replaced by polar aprotic solvents, such as N-methyl-2-pyrrolidone (NMP) and dimethylsulfoxide (DMSO), without loss of colloidal stability...

Organic carbon cycling is a fundamental process that underpins energy transfer through the biosphere. However, little is known about the rates of particulate organic carbon processing in the hyporheic zone of intermittent streams, which is often the only wetted environment remaining when surface flows cease. We used leaf litter and cotton decomposition assays, as well as rates of microbial respiration, to quantify rates of organic carbon processing in surface and hyporheic environments of intermittent and perennial streams under a range of substrate saturation conditions...

The development of coronary heart disease can be divided into preocclusion and postocclusion steps. We previously showed that cell wall polysaccharides consisting of a high content of arabinose and/or xylose, such as apple pectin, protected against myocardial injury by inhibiting postocclusion steps. We hypothesized that xyloglucan, another apple cell wall polysaccharide that consists of a high content of xylose, might also show myocardial protection. To test the hypothesis, rats were supplemented with either tamarind xyloglucan (TXG) (1, 10, and 100 mg/kg per day) or cotton cellulose (CCL) (100mg/kg per day) for 3 days...

JASMONATE ZIM-domain (JAZ) family proteins are involved in regulating diverse biological processes in plants. However, their functions have not been well characterized in cotton (Gossypium spp.). In the present study, 13, 15, 25, and 30 JAZ genes were identified in Gossypium arboretum, Gossypium raimondii, Gossypium barbadense and Gossypium hirsutum respectively, based on gene homology. Selection and variation analyses showed that the SNP density of GhJAZ genes in wild species was much higher than that in domesticated species...
