Our previous genetic analysis of a tetraploid wild wheat species, Aegilops peregrina, predicted that a single gene per haploid genome, Bgc-1, controls B-type starch granule content in the grain. To test whether bread wheat (Triticum aestivum L.) has orthologous Bgc-1 loci, we screened a population of γ-irradiated bread wheat cv. Paragon for deletions of the group 4 chromosomes spanning Bgc-1. Suitable deletions, each encompassing ~600-700 genes, were discovered for chromosomes 4A and 4D. These two deletions are predicted to have 240 homoeologous genes in common...

Quantification of the tissue and cellular structure of plant material is essential for the study of a variety of plant sciences applications. Currently, many methods for sectioning plant material are either low throughput or involve free-hand sectioning which requires a significant amount of practice. Here, we present an updated method to provide rapid and high-quality cross sections, primarily of root tissue but which can also be readily applied to other tissues such as leaves or stems. To increase the throughput of traditional agarose embedding and sectioning, custom designed 3D printed molds were utilized to embed 5-15 roots in a block for sectioning in a single cut...

Meningiomas represent the most common primary intracranial neoplasm treated by neurosurgeons. Although multimodal treatment of meningiomas includes surgery, radiation-based treatments, and occasionally medical therapy, surgery remains the mainstay of treatment for most symptomatic meningiomas. Because of the intricate relationship of the dura mater and arachnoid mater with the central nervous system and cranial nerves, meningiomas can arise anywhere along the skull base or convexities, and occasionally even within the ventricular system, thereby mandating a catalog of surgical approaches that neurosurgeons may employ to individualize treatment for patients...

BACKGROUND: The effect of photodamage on facial stratum corneum (SC) is still poorly understood. OBJECTIVE: To describe the SC proteome from tape strippings of Caucasian SC from photoexposed cheek and photoprotected post-auricular (PA) site, a global analysis of photodamage on the skin will be developed leading to a better understanding of keratinocyte signalling pathways and identification of new molecular targets for the treatment of photoaged skin. METHODS: Female Caucasian subjects had nine consecutive tape strippings taken from their cheeks and PA site...

In the latter part of the 20th century, drug development in cardiovascular diseases (CVDs) was a paragon of "modern" therapeutics, bringing about a substantial number of effective, well-tolerated agents targeting some of the most prevalent diseases of the Western world. These drugs were often examples of rational drug development targeting specific pathophysiologic pathways previously elucidated through basic research (e.g., targeting of the renin-angiotensin system or the cholesterol synthesis pathway). The widespread adoption of these ground-breaking medications in practice and into medical guidelines undoubtedly played a role in the fall of morbidity and mortality from CVD in the United States in recent decades...

Precision medicine requires clinical trials that are able to efficiently enroll subtypes of patients in whom targeted therapies can be tested. To reduce the large amount of time spent screening, identifying, and recruiting patients with specific subtypes of heterogeneous clinical syndromes (such as heart failure with preserved ejection fraction [HFpEF]), we need prescreening systems that are able to automate data extraction and decision-making tasks. However, a major obstacle is the vast amount of unstructured free-form text in medical records...

The development of the promising agent sacubitril/valsartan, known as an angiotensin receptor blocker-neprilysin inhibitor (ARNI), to improve heart failure (HF) management, may benefit morbidity, mortality, and readmission rates in patients with HF. The PARADIGM-HF trial demonstrated that the ARNI can reduce morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF), while ongoing PARAMOUNT and PARAGON-HF trials determined whether the ARNI has morbidity and mortality benefits in patients with heart failure with preserved ejection fraction (HFpEF)...

The technique of triggering the cremasteric reflex and its respective signaling pathway is not described uniformly throughout the literature. As this reflex is a useful sign in diagnosing testicular torsion, orchitis, varicocele, and undescended testis, it seems desirable to identify and define the correct mechanism. Our aim was to investigate how the cremasteric reflex and its signaling pathway are described in the current literature and how the variability of the innervation of the inguinal region could affect the frequency of this reflex...

Long considered a paragon among low- and middle-income countries in its provision of primary health care, Costa Rica reformed its primary health care system in 1994 using a model that, despite its success, has been generally understudied: basic integrated health care teams. This case study provides a detailed description of Costa Rica's innovative implementation of four critical service delivery reforms and explains how those reforms supported the provision of the four essential functions of primary health care: first-contact access, coordination, continuity, and comprehensiveness...

Understanding the genomic complexity of bread wheat (Triticum aestivum L.) is a cornerstone in the quest to unravel the processes of domestication and the following adaptation of domesticated wheat to a wide variety of environments across the globe. Additionally, it is of importance for future improvement of the crop, particularly in the light of climate change. Focusing on the adaptation after domestication, a nested association mapping (NAM) panel of 60 segregating biparental populations was developed, mainly involving landrace accessions from the core set of the Watkins hexaploid wheat collection optimized for genetic diversity...

Successive single day transfers of pot-grown wheat to high temperature (35/30°C day/night) replicated controlled environments, from the second node detectable to the milky-ripe growth stages, provides the strongest available evidence that the fertility of wheat can be highly vulnerable to heat stress during two discrete peak periods of susceptibility: early booting [decimal growth stage (GS) 41-45] and early anthesis (GS 61-65). A double Gaussian fitted simultaneously to grain number and weight data from two contrasting elite lines (Renesansa, listed in Serbia, Ppd-D1a, Rht8; Savannah, listed in UK, Ppd-D1b, Rht-D1b) identified peak periods of main stem susceptibility centered on 3 (s...

The first series of radical cystectomy with a definition of surgical landmarks was published in 1949 and was characterized by a high perioperative mortality and a 5-year survival rate around 50%. Decades later, nevertheless many surgical progresses were made and the perioperative mortality dropped to 2,5%, this had not lead to an improvement of long term survival rates, also because a standardization of the procedure is still missing. Areas covered: Radical cystectomy is performed with different surgical techniques obmitting a standardization...
