Nocturnal plant respiration is under strong non-temperature control.

Most biological rates depend on the rate of respiration. Temperature variation is typically considered the main driver of daily plant respiration rates, assuming a constant daily respiration rate at a set temperature. Here, we show empirical data from 31 species from temperate and tropical biomes to demonstrate that the rate of plant respiration at a constant temperature decreases monotonically with time through the night, on average by 25% after 8 h of darkness.

Analysis of COVID-19 pandemic in USA, using Topological Weighted Centroid.

The first case of COVID-19 in USA was reported on January 20, 2020. The number of COVID-19 confirmed cases and death has increased since the first reported case and the outbreak has appeared in all states. This paper analyzes disease outbreak using Topological Weighted Centroid (TWC), which is a data driven intelligent geographical dynamical system that models disease spread in space and time.

Patient Positioning Guidelines for Gastrointestinal Endoscopic Procedures.

Patient positioning during gastrointestinal endoscopic procedures has received minimal attention compared with surgical procedures performed in the surgical setting. However, prolonged endoscopic interventions on patients and the increasing requirement for general anesthesia have changed to need for patient positioning guidelines. The objective of this study was to test whether patient positioning guidelines for surgical procedures in surgical suites are suitable for gastrointestinal endoscopic procedures without negatively impacting safety and procedure duration.

Consensus statement: Safe Airway Society principles of airway management and tracheal intubation specific to the COVID-19 adult patient group.

Introduction: This statement was planned on 11 March 2020 to provide clinical guidance and aid staff preparation for the coronavirus disease 2019 (COVID-19) pandemic in Australia and New Zealand. It has been widely endorsed by relevant specialty colleges and societies.

Main Recommendations: Generic guidelines exist for the intubation of different patient groups, as do resources to facilitate airway rescue and transition to the "can't intubate, can't oxygenate" scenario.

Pathogen infection risk to recreational water users, associated with surface waters impacted by de facto and indirect potable reuse activities.

Water deficit, exacerbated by global population increases and climate change, necessitates the investigation of alternative non-traditional water sources to augment existing supplies. Indirect potable reuse (IPR) represents a promising alternative water source in water-stressed regions. Of high concern is the presence of pathogenic microorganisms in wastewater, such as enteric viruses, protozoa and bacteria.

Multinodular and vacuolating neuronal tumors in epilepsy: dysplasia or neoplasia?

Multinodular and vacuolating neuronal tumor (MVNT) is a new pattern of neuronal tumour included in the recently revised WHO 2016 classification of tumors of the CNS. There are 15 reports in the literature to date. They are typically associated with late onset epilepsy and a neoplastic vs.

Left-sided breast cancer irradiation using rotational and fixed-field radiotherapy.

The 3-dimensional conformal radiotherapy (3DCRT) technique is the standard for breast cancer radiotherapy. During treatment planning, not only the coverage of the planning target volume (PTV) but also the minimization of the dose to critical structures, such as the lung, heart, and contralateral breast tissue, need to be considered. Because of the complexity and variations of patient anatomy, more advanced radiotherapy techniques are sometimes desired to better meet the planning goals.

Resource need and use of multiethnic caregivers of elders in their homes.

Aims: The aim of this study was to predict South Florida family caregivers' need for and use of informal help or formal services, specifically, to explore the predictive power of variables suggested by the Caregiver Identity Theory and the literature and develop and test a structural model.

Background: In the USA, most of the care to older adults is given by family members. Caregivers make economic and social sacrifices that endanger their health.

CD4+ T cells provide intermolecular help to generate robust antibody responses in vaccinia virus-vaccinated humans.

Immunization with vaccinia virus elicits a protective Ab response that is almost completely CD4(+) T cell dependent. A recent study in a rodent model observed a deterministic linkage between Ab and CD4(+) T cell responses to particular vaccinia virus proteins suggesting that CD4(+) T cell help is preferentially provided to B cells with the same protein specificity (Sette et al. 2008.

Safety and immunogenicity of IMVAMUNE® smallpox vaccine using different strategies for a post event scenario.

Introduction: Reintroduction of Variola major as an agent of bioterrorism remains a concern. A shortened dosing schedule of Bavarian Nordic's (BN) IMVAMUNE(®) (modified vaccinia Ankara vaccine against smallpox) was compared to the currently recommended 0- and 28-day schedule for non-inferiority by evaluating the magnitude and kinetics of the immune responses.

Methods: Subjects were assigned to receive IMVAMUNE or placebo administered subcutaneously on Days 0 and 7, Days 0 and 28, or Day 0.

Patterns of caregiving of Cuban, other Hispanic, Caribbean Black, and White elders in South Florida.

Caregivers in Miami, Florida (185 Cubans, 108 other Hispanics, 229 non-Hispanic Whites, and 73 Caribbean Blacks) were described and compared along demographic and health variables, cultural attitudes, and caregiving behaviors. Participants were recruited at random through Home Health Services (61 %) and convenience sampling in the community (39 %), and interviewed at their home. Standardized instruments and measures constructed for this study were pretested.

Domestic abuse against elder women and perceived barriers to help-seeking.

The study's (n = 447) purposes were to (1) describe relationships of abuser behavior to elder women's perception of barriers to help-seeking; (2) compare fit of model to participants' levels of abuse, race-ethnicity, age, and gender and relationship of identified close other; and (3) determine extent to which the model differentiated relationship of abuser to participant and level of abuse. Analyses identified six factors contributing to the overall barrier score, accounting for 84% of total variance (χ2/df = 1.527, CFI = .

Self-regulation and eudaimonic well-being across adulthood.

Unlabelled: BACKGROUND/STUDY CONTEXT: The authors developed and tested a model to examine the developmental self-regulatory pathways that lead to optimal eudaimonic well-being across adulthood.

Methods: Measures of goal adjustment, optimization, possible selves, and well-being were obtained from 590 adults ranging in age from 17 to 94. Structural equation modeling was used to determine the whether there were age-differential pathways among the developmental self-regulatory processes and well-being.

Analysis of variola and vaccinia virus neutralization assays for smallpox vaccines.

Possible smallpox reemergence drives research for third-generation vaccines that effectively neutralize variola virus. A comparison of neutralization assays using different substrates, variola and vaccinia (Dryvax and modified vaccinia Ankara [MVA]), showed significantly different 90% neutralization titers; Dryvax underestimated while MVA overestimated variola neutralization. Third-generation vaccines may rely upon neutralization as a correlate of protection.

Health and cultural determinants of voluntary HIV testing and counseling among middle-aged and older Latina women.

The rate of cases of HIV/AIDS in older people is increasing; indeed one out of every four people with HIV/AIDS is over age 50. This study describes the correlates of HIV Voluntary Counseling and Testing (VCT) using structural equation modeling techniques for a sample of 135 middle-aged and middle-aged and older Latinas in South Florida. Over 60% of participants had been tested for HIV.

Live and inactivated influenza vaccines induce similar humoral responses, but only live vaccines induce diverse T-cell responses in young children.

Background: Two doses of either trivalent live attenuated or inactivated influenza vaccines (LAIV and TIV, respectively) are approved for young children (≥ 24 months old for LAIV and ≥ 6 months old for TIV) and induce protective antibody responses. However, whether combinations of LAIV and TIV are safe and equally immunogenic is unknown. Furthermore, LAIV is more protective than TIV in children for unclear reasons.

Esophageal cancer patients undergoing external beam radiation after placement of self-expandable metal stents: is there a risk of radiation dose enhancement?

Background: Self-expandable metal stents (SEMSs) are used for palliation of malignant dysphagia. It is not known whether dose adjustments are required when there is a stent in the radiation field.

Objective: To measure the effects of esophageal stents of various designs and materials on radiation dose to the tissue adjacent to the stent in the radiation field to determine whether there should be any dose adjustment.

Respiration induced heart motion and indications of gated delivery for left-sided breast irradiation.

Purpose: To investigate respiration-induced heart motion for left-sided breast irradiation using a four-dimensional computed tomography (4DCT) technique and to determine novel indications to assess heart motion and identify breast patients who may benefit from a gated treatment.

Methods And Materials: Images of 4DCT acquired during free breathing for 20 left-sided breast cancer patients, who underwent whole breast irradiation with or without regional nodal irradiation, were analyzed retrospectively. Dose distributions were reconstructed in the phases of 0%, 20%, and 50%.

Cocaine reduces thymic endocrine function: another mechanism for accelerated HIV disease progression.

Thymulin is a thymic peptide important for the maturation and differentiation of immature thymocytes, which have been found to be depressed in patients with low-level CD4(+) cell recovery despite viral control. Substance use is associated with faster progression of HIV disease, which has been ascribed to poor adherence to antiretroviral medication. Recent findings of an association between cocaine use and decline in CD4(+) cell counts independent of antiretroviral adherence indicate alternative mechanisms for disease progression.

Improved survival in patients with early stage low-grade follicular lymphoma treated with radiation: a Surveillance, Epidemiology, and End Results database analysis.

Background: External beam radiation therapy (RT) is the standard treatment for stage I-II, grade 1-2 follicular lymphoma. Because of an indolent natural history, some advocate alternative management strategies, including watchful waiting for this disease. The relative improvement in outcomes for patients treated with and without RT has never been tested in randomized trials.

Food safety education using an interactive multimedia kiosk in a WIC setting: correlates of client satisfaction and practical issues.

Objective: To assess acceptability of food safety education delivered by interactive multimedia (IMM) in a Supplemental Nutrition Program for Women, Infants and Children Program (WIC) clinic.

Methods: Female clients or caregivers (n=176) completed the food-handling survey; then an IMM food safety education program on a computer kiosk. Satisfaction with program, participant demographics, and change in food-handling behavior were assessed by univariate analyses.

Age-associated decrease in TLR function in primary human dendritic cells predicts influenza vaccine response.

We evaluated TLR function in primary human dendritic cells (DCs) from 104 young (age 21-30 y) and older (> or =65 y) individuals. We used multicolor flow cytometry and intracellular cytokine staining of myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) and found substantial decreases in older compared with young individuals in TNF-alpha, IL-6, and/or IL-12 (p40) production in mDCs and in TNF-alpha and IFN-alpha production in pDCs in response to TLR1/2, TLR2/6, TLR3, TLR5, and TLR8 engagement in mDCs and TLR7 and TLR9 in pDCs. These differences were highly significant after adjustment for heterogeneity between young and older groups (e.
