Phenotypic and transcriptomic responses of diverse rice accessions to transient heat stress during early grain development.

Heat stress (HS) occurring during the grain-filling period has a detrimental effect on grain yield and quality in rice (). The development of heat-resilient cultivars could partly solve this issue if tolerant alleles can be identified and incorporated into the germplasm. In this study, we posit that some of the phenotypic variations for heat resilience during grain development could be due to variations in gene expression among accessions.

Natural variation in LONELY GUY-Like 1 regulates rice grain weight under warmer night conditions.

Global nighttime temperatures are rising at twice the rate of daytime temperatures and pose a challenge for rice (Oryza sativa) production. High nighttime temperature (HNT) stress affects rice yield by reducing grain weight, size, and fertility. Although the genes associated with these yield parameters have been identified and characterized under normal temperatures, the genetic basis of grain weight regulation under HNT stress remains less explored.

A snapshot of the transcriptome of Medicago truncatula (Fabales: Fabaceae) shoots and roots in response to an arbuscular mycorrhizal fungus and the pea aphid (Acyrthosiphon pisum) (Hemiptera: Aphididae).

Plants simultaneously interact with belowground symbionts such as arbuscular mycorrhizal (AM) fungi and aboveground antagonists such as aphids. Generally, plants gain access to valuable resources including nutrients and water through the AM symbiosis and are more resistant to pests. Nevertheless, aphids' performance improves on mycorrhizal plants, and it remains unclear whether a more nutritious food source and/or attenuated defenses are the contributing factors.

Neonates and Periparturient Mares: Tips and Tricks for Diagnosis and Management.

Colic is a common presenting complaint in foals. Unfortunately, evaluation of foals with colic can be difficult due to the common clinical presentation of acute abdominal pain attributable to a wide variety of disorders and a broad range of etiologies. Similar to foals, colic is one of the most common diseases of pregnant and periparturient mares.

Digital Health Solutions for Weight Loss and Obesity: A Narrative Review.

Personal exercise programmes have long been used and prescribed for weight loss and the improvement of quality of life in obese patients. While individualised programmes are usually the preferred option, they can be more costly and challenging to deliver in person. A move to digital programmes with a wider reach has commenced, and demand has increased due to the SARS-CoV-2 pandemic.

Rice regulates natural variation for grain quality under heat stress.

Heat stress occurring during rice () grain development reduces grain quality, which often manifests as increased grain chalkiness. Although the impact of heat stress on grain yield is well-studied, the genetic basis of rice grain quality under heat stress is less explored as quantifying grain quality is less tractable than grain yield. To address this, we used an image-based colorimetric assay (Red, R; and Green, G) for genome-wide association analysis to identify genetic loci underlying the phenotypic variation in rice grains exposed to heat stress.

Health disparities in the management of ACL injuries: How socioeconomic status, insurance, and race influence care.

Health care disparities and racial health inequities significantly influence health care delivery and patient outcomes, including for people with injuries of the anterior cruciate ligament (ACL). This narrative review explores factors that may influence the management of ACL injuries. Studies that have discussed potential social barriers to treatment such as socioeconomic status (SES), insurance status, educational level, and cost of treatment were identified by searching databases such as EBSCO Host, PubMed, and Galileo for the index years from 2008 to 2020.

The Healthy Hawai'i Strategic Plan 2030: A Roadmap for Preventing and Managing Chronic Disease and Envisioning a Healthy and Equitable Future.

In June 2021, over 200 stakeholders, advocates, and visionaries gathered to launch the Healthy Hawai'i Strategic Plan 2030 (HHSP), a 10-year strategic plan for improving the health of Hawai'i residents by preventing and reducing chronic disease and advancing health equity. The HHSP is a guide to enable coordination across common risk factors, program areas, interventions, and strategies for chronic disease prevention and control. Developed during the COVID-19 pandemic, which revealed major areas of susceptibility in our health system infrastructure and magnified existing disparities, the HHSP prioritizes health equity and strives to create sustainable change to transform communities, schools, health care and worksites to support the health of the people of Hawai'i.

Micropropagation of Rare Jacq. and Preliminary Studies on Antioxidant Capacity and Anti-Cancer Potential.

We report the development of in vitro propagation protocols through an adventitious shoot induction pathway for a rare and medicinal In vitro propagation studies using nodal explants showed MS medium supplemented with 10 µM 6-Benzylaminopurine induced the highest number of adventitious shoots in a time-dependent manner. A ten-day incubation was optimum for shoot bud induction as longer exposures resulted in hyperhydricity of the explants and shoots induced. We also report preliminary evidence of EHA105-mediated gene transfer transiently expressing the green fluorescent protein in this species.

Return-to-Play Considerations After COVID-19 Infection in Elite Athletes.

The COVID-19 pandemic has created a unique challenge for sports medicine staffs as they attempt to safely transition elite athletes into sport participation after COVID-19 infections. Athletes must isolate for a period after testing positive for COVID-19 to prevent the spread of the virus in a community. After an isolation period, a battery of cardiac tests must be given to assess whether an athlete is ready to begin a reconditioning protocol.

Endoplasmic reticulum stress pathway mediates the early heat stress response of developing rice seeds.

A transient heat stress occurring during early seed development in rice (Oryza sativa) reduces seed size by altering endosperm development. However, the relationship between the timing of the stress and specific developmental stage on heat sensitivity is not well-understood. To address this, we imposed a series of non-overlapping heat stress treatments and found that young seeds are most sensitive during the first two days after flowering.

Optimization of Micropropagation and Genetic Transformation Protocols for Paulownia elongata : A Short Rotation Fast Growing Bioenergy Tree.

Various steps of micropropagation include selection of suitable explant, establishment of adventitious shoot induction cultures, proliferation, rooting, and acclimatization of the resulting plantlets. A systematic protocol is provided for the micropropagation and Agrobacterium tumefaciens-mediated genetic transformation of a fast growing, multipurpose tree, Paulownia elongata. Our studies show that optimum shoot induction is on half leaf with petiole explant on MS medium supplemented with 25 μM thidiazuron and 10 μM indole-3 acetic acid.

: An Open-Source GUI for Seed Image Analysis.

Accurate measurement of seed size parameters is essential for both breeding efforts aimed at enhancing yields and basic research focused on discovering genetic components that regulate seed size. To address this need, we have developed an open-source graphical user interface (GUI) software, that determines seed size and shape (including area, perimeter, length, width, circularity, and centroid), and seed color with capability to process a large number of images in a time-efficient manner. In this context, our application takes ∼2 s for analyzing an image, i.

Identifying best practices in adoption, implementation and enforcement of flavoured tobacco product restrictions and bans: lessons from experts.

Objective: To identify recommended components for adopting, implementing and enforcing bans or restrictions targeting flavoured tobacco products.

Methods: Between April and June 2019, semistructured interviews were conducted with 17 high-level experts across the USA and Canada with expertise in flavoured tobacco product policies. Participants included health department staff, researchers, legal professionals and local government officials.

Allelic variation in rice Fertilization Independent Endosperm 1 contributes to grain width under high night temperature stress.

A higher minimum (night-time) temperature is considered a greater limiting factor for reduced rice yield than a similar increase in maximum (daytime) temperature. While the physiological impact of high night temperature (HNT) has been studied, the genetic and molecular basis of HNT stress response remains unexplored. We examined the phenotypic variation for mature grain size (length and width) in a diverse set of rice accessions under HNT stress.

The Healthy Hawai'i Initiative: insights from two decades of building a culture of health in a multicultural state.

Background: The Healthy Hawai'i Initiative was created in 2000 with tobacco settlement funds as a theory-based statewide effort to promote health-supporting environments through systems and policy change. Still active today, it is imbedded explicitly in a multi-sectoral, social ecological approach, effectively striving to build a culture of health before this was the name for such an ambitious effort.

Methods: From interviews with key informants, we analyze two decades of the Healthy Hawai'i Initiative (HHI) in the context of the Robert Wood Johnson Foundation (RWJF) Culture of Health Action Framework (CHAF).

Divergent phenotypic response of rice accessions to transient heat stress during early seed development.

Increasing global surface temperatures is posing a major food security challenge. Part of the solution to address this problem is to improve crop heat resilience, especially during grain development, along with agronomic decisions such as shift in planting time and increasing crop diversification. Rice is a major food crop consumed by more than 3 billion people.

Insights in Public Health: Formative Factors for a Statewide Tobacco Control Advocacy Infrastructure: Insights from Hawai'i.

Hawai'i has comprehensive statewide tobacco control policies and was the first US state to raise the minimum age of sale, purchase, and possession of tobacco products to age 21 ("Tobacco 21") in a policy including not just cigarettes, but also electronic smoking devices and other tobacco products. This insights article provides strategic thinking about tobacco control advocacy planning. Specifically, we identify formative factors critical to building and sustaining our cross-sector, statewide advocacy infrastructure that has been able to address many ongoing challenges of tobacco-use prevention and control over time.

A Time to Live and a Time to Die: Heterotopian Spatialities and Temporalities in a Pediatric Palliative Care Team.

The death of a child creates especially poignant feelings and extreme stress, distress, and devastation for family members and healthcare providers. In addition, serious or long-term illness forces a reconstruction of our experiences with time and space. In this paper, we report on a long-term ethnographic study of a Pediatric Palliative Care Team (PPCT).
