Plants defend themselves against pathogens by activating an array of immune responses. Unfortunately, immunity programs may also cause unintended collateral damage to the plant itself. The quantitative disease resistance gene ACCELERATED CELL DEATH 6 (ACD6) serves to balance growth and pathogen resistance in natural populations of Arabidopsis thaliana. An autoimmune allele, ACD6-Est, which strongly reduces growth under specific laboratory conditions, is found in over 10% of wild strains. There is, however, extensive variation in the strength of the autoimmune phenotype expressed by strains with an ACD6-Est allele, indicative of genetic modifiers...

BACKGROUND: Contact dermatitis to hair dyes remains a health concern. Regulations in many countries require consumer self-testing for hair dyes, but no standardized procedure exists. OBJECTIVE: The aim of this study was to develop a self-test protocol for an allergy alert test (AAT) that can elicit a self-noticeable alert signal in p-phenylenediamine (PPD)-allergic consumers. METHODS: Simulating consumer use conditions (open application for 45 minutes after mixing with a developer), PPD-positive hair dye-allergic subjects and PPD-negative control subjects were tested on the forearm and behind the ear with experimental products containing 0...

Depression is one of the most common comorbid conditions in Internet Gaming Disorder (IGD). Although there have been many studies on the pathophysiology of IGD, the neurobiological basis underlying the close association between depression and IGD has not been fully clarified. Previous neuroimaging studies have demonstrated functional and structural abnormalities in the anterior cingulate cortex (ACC) in IGD patients. In this study, we explored functional connectivity (FC) abnormalities involving subregions of the ACC in IGD subjects with comorbid depression...

The Functional Movement Screen (FMS) is a popular movement screen used by rehabilitation, as well as strength and conditioning, professionals. The FMS, like other movement screens, identifies movement dysfunction in those at risk of, but not currently experiencing, signs or symptoms of a musculoskeletal injury. Seven movement patterns comprise the FMS, which was designed to screen fundamental movement requiring a balance between stability and mobility. The 7 movement patterns are summed to a composite FMS score...

INTRODUCTION: Men and women joining the military undergo the same training, often in mixed-sex platoons. Given the inherent physiological and physical performance differences between men and women, it is reasonable to question whether sex differences exist in the adaptation to military training and, therefore, whether sex-specific training should be employed to optimise training adaptations. OBJECTIVE: To systematically review the literature evaluating changes in the physical performance of men and women following military training...

PURPOSE OF REVIEW: Hip fractures have catastrophic consequences. The purpose of this article is to review recent developments in high-resolution magnetic resonance imaging (MRI)-guided finite element analysis (FEA) of the hip as a means to determine subject-specific bone strength. RECENT FINDINGS: Despite the ability of DXA to predict hip fracture, the majority of fractures occur in patients who do not have BMD T scores less than - 2.5. Therefore, without other detection methods, these individuals go undetected and untreated...

Uropathogenic Escherichia coli (UPEC) are the major causative agents of urinary tract infections, employing numerous molecular strategies to contribute to adhesion, colonization, and persistence in the bladder niche. Identifying strategies to prevent adhesion and colonization is a promising approach to inhibit bacterial pathogenesis and to help preserve the efficacy of available antibiotics. This approach requires an improved understanding of the molecular determinants of adhesion to the bladder urothelium...

Cardiovascular disease remains a leading cause of morbidity and mortality globally. Changing natural history of the disease due to improved care of acute conditions and ageing population necessitates new strategies to tackle conditions which have more chronic and indolent course. These include an increased deployment of safe screening methods, life-long surveillance, and monitoring of both disease activity and tailored-treatment, by way of increasingly personalized medical care. Cardiovascular magnetic resonance (CMR) is a non-invasive, ionising radiation-free method, which can support a significant number of clinically relevant measurements and offers new opportunities to advance the state of art of diagnosis, prognosis and treatment...

Open bone fractures are not only difficult to heal but also are at a high risk of infections. Annual cases of fractures which result from osteoporosis amount to approximately 9 million. Endogenously released nitric oxide (NO) has been shown to play a role in osteogenic differentiation in addition to eradicating infection against a wide variety of pathogens. In the current work, antimicrobial NO releasing 3D bone scaffolds were fabricated using S-nitroso-N-acetyl-penicillamine (SNAP) as the NO donor. During fabrication, nano-hydroxyapatite (nHA) was added to each of the scaffolds in the concentration range of 10-50 wt % in nHA-starch-alginate and nHA-starch-chitosan scaffolds...

It is now 100 years since deficiency of vitamin D was identified as the cause of rickets and osteomalacia (see Figure). Since then, enormous amounts of work have been undertaken elucidating the synthesis and catabolism of vitamin D, the regulation of these processes, and the mechanisms of action of vitamin D metabolites on calcium and bone metabolism. The findings of the early studies, mainly in children, that vitamin D promotes the growth and mineralisation of the skeleton have been generalised to other contexts, and vitamin D has become widely used in many conditions associated with decreases in skeletal strength, particularly in the prevention and treatment of osteoporosis...

A 17 β -estradiol (E2) degrading strain (designated as Wu-SP1) was isolated from the activated sludge collected from a wastewater treatment plant (WWTP) in Xi'an. The strain was identified as Fusarium sp. according to 18S rDNA sequence and phylogenetic analysis. The optimal pH and temperature for E2 degradation were 6 and 30℃, respectively. Under these conditions, the E2 biodegradation rate of 2 mg·L-1 E2 amounted to 92.5% within 48 h by this strain. The kinetics of E2 degradation by the strain KY123915 were in good accord with the first-order equation, with the concentration ranged from 10 to 500 mg·L-1 ...

BACKGROUND: Peri-articular injury may result in functional deficits and pain. In particular, post-traumatic elbow stiffness is a debilitating condition, precluding patients from performing activities of daily living. As such, clinicians and basic scientists alike, aim to develop novel therapeutic interventions to prevent and treat elbow stiffness; thereby reducing patient morbidity. Yet, there is a paucity of pre-clinical models of peri-articular stiffness, especially of the upper extremity, necessary to develop and test the efficacy of therapeutics...

BACKGROUND: Adults with sedentary lifestyles seem to face a higher risk of falling in their later years. Several causes, such as impairment of strength, coordination, and cognitive function, influence worsening health conditions, including balancing ability. Many modalities can be applied to improve the balance function and prevent falling. Several studies have also recorded the effects of balance training in elderly adults for fall prevention. Accordingly, the aim of this study is to define the effect of virtual reality-based balance training on motor learning and postural control abilities in healthy adults...

The recent discovery that myosin has two distinct states in relaxed muscle-disordered relaxed (DRX) and super-relaxed (SRX)-provides another factor to consider in our fundamental understanding of the aging mechanism in skeletal muscle, since myosin is thought to be a potential contributor to dynapenia (age-associated loss of muscle strength independent of atrophy). The primary goal of this study was to determine the effects of age on DRX and SRX states and to examine their sex specificity. We have used quantitative fluorescence microscopy of the fluorescent nucleotide analog 2'/3'-O-(N-methylanthraniloyl) ATP (mantATP) to measure single-nucleotide turnover kinetics of myosin in skinned skeletal muscle fibers under relaxing conditions...
