Fine-scale topographic influence on the spatial distribution of tree species diameter in old-growth beech (Fagus orientalis Lipsky.) forests, northern Iran.

The Hyrcanian forest in northern Iran is threatened by human use and encroachment and has suffered degradation in some areas. The forest has been declared a World Heritage Site and management in the region is shifting from timber production to conservation. There is considerable interest in developing a greater understanding of these diverse forest communities to inform forest management and multiple use plans to maintain the diversity and resilience of these forests.

The 2018 European heatwave led to stem dehydration but not to consistent growth reductions in forests.

Heatwaves exert disproportionately strong and sometimes irreversible impacts on forest ecosystems. These impacts remain poorly understood at the tree and species level and across large spatial scales. Here, we investigate the effects of the record-breaking 2018 European heatwave on tree growth and tree water status using a collection of high-temporal resolution dendrometer data from 21 species across 53 sites.

A terahertz time-domain super-resolution imaging method using a local-pixel graph neural network for biological products.

The low image acquisition speed of terahertz (THz) time-domain imaging systems limits their application in biological products analysis. In the current study, a local pixel graph neural network was built for THz time-domain imaging super-resolution. The method could be applied to the analysis of any heterogeneous biological products as it only required a small number of sample images for training and particularly it focused on THz feature frequencies.

Challenges and opportunities for nutrition education and training in the health care professions: intraprofessional and interprofessional call to action.

Understanding and applying nutrition knowledge and skills to all aspects of health care are extremely important, and all health care professions need basic training to effectively assess dietary intake and provide appropriate guidance, counseling, and treatment to their patients. With obesity rates at an all-time high and the increasing prevalence of diabetes projected to cost the Federal government billions of dollars, the need for interprofessional nutrition education is paramount. Physicians, physician assistants, nurses, nurse practitioners, pharmacists, dentists, dental hygienists, occupational therapists, physical therapists, speech and language pathologists, and others can positively affect patient care by synchronizing and reinforcing the importance of nutrition across all specialty areas.

European consumer attitudes on the associated health benefits of neutraceutical-containing processed meats using Co-enzyme Q10 as a sample functional ingredient.

This study accumulated European consumer attitudes towards processed meats and their use as a functional food. A survey was set up using an online web-application to gather information on consumer perception of processed meats as well as neutraceutical-containing processed meats. 548 responses were obtained and statistical analysis was carried out using a statistical software package.

Effect of cooking and in vitro digestion on the stability of co-enzyme Q10 in processed meat products.

The use of CoQ10 fortification in the production of a functional food has been demonstrated in the past but primarily for dairy products. This study aimed to determine the bio-accessibility of CoQ10 in processed meat products, beef patties and pork breakfast sausages, fortified with CoQ10. Both the patties and sausages were fortified with a micellarized form of CoQ10 to enhance solubility to a concentration of 1mg/g of sample (NovaSolQ®).

Possible causes of the recent rapid increase in the radial increment of silver fir in the Western Carpathians.

Silver fir is one of the most productive and ecologically valuable native European tree species, however, it has been experiencing decline which has periodically occurred over its natural range. This paper aims to investigate the recent climate-growth relationships of silver fir (Abies alba Mill.) and its temporal change along the course of its life.

Cytokine secretion and latent herpes virus reactivation with 28 days of horizontal hypokinesia.

Introduction: Hypokinesia is associated with spaceflight and prolonged illnesses and may lead to secondary immune deficiency.

Methods: The distribution of immunocytes in whole blood, mitogen-induced cytokine secretion in vitro, Epstein-Barr virus (EBV) reactivation, and plasma cortisol levels were studied in 13 healthy volunteers subjected to a horizontal bed rest (BR) regime for 28 d. Samples were collected before the study, weekly during BR, and then 3-5 d after the regime ended.

Implementing a diabetes prevention program in a rural African-American church.

Objectives: The purpose of this study was to determine the feasibility of implementing a diabetes prevention program (DPP) in a rural African-American church.

Methods: A six-session DPP, modeled after the successful National Institutes of Health (NIH) DPP, was implemented in a rural African-American church. Adult members of the church identified as high risk for diabetes, based on results of a risk questionnaire, were screened with a fasting glucose.

Clonogenic analysis reveals reserve stem cells in postnatal mammals. II. Pluripotent epiblastic-like stem cells.

Undifferentiated cells have been identified in the prenatal blastocyst, inner cell mass, and gonadal ridges of rodents and primates, including humans. After isolation these cells express molecular and immunological markers for embryonic cells, capabilities for extended self-renewal, and telomerase activity. When allowed to differentiate, embryonic stem cells express phenotypic markers for tissues of ectodermal, mesodermal, and endodermal origin.

Adult reserve stem cells and their potential for tissue engineering.

Tissue restoration is the process whereby multiple damaged cell types are replaced to restore the histoarchitecture and function to the tissue. Several theories have been proposed to explain the phenomenon of tissue restoration in amphibians and in animals belonging to higher orders. These theories include dedifferentiation of damaged tissues, transdifferentiation of lineage-committed progenitor cells, and activation of reserve precursor cells.

Type 1 vs. type 2 cytokine secretion in vitro and its regulation by hydrocortisone in humans subjected to 120-day anti-orthostatic bed-rest regime.

Head-Down Bed-Rest (HDBR) mimics some of the physiological stress effects of microgravity. Six healthy volunteers were subjected to bed-rest for 120 days. Blood samples were collected one month before (PRE), on day 110 of HDBR (DAY 110), and on the 7th day after bed-rest regime ends (POST).

Longitudinal and horizontal integration of nutrition science into medical school curricula.

The overall goal of our Nutrition Academic Award (NAA) medical nutrition program at Mercer University School of Medicine is to develop, implement and evaluate a medical education curriculum in nutrition and other aspects of cardiovascular disease (CVD) prevention and patient management with emphasis on the training of primary care physicians for medically underserved populations. The curriculum is 1) vertically integrated throughout all 4 y of undergraduate medical education, including basic science, clinical skills, community science and clinical clerkships as well as residency training; 2) horizontally integrated to include allied healthcare training in dietetics, nursing, exercise physiology and public health; and 3) designed as transportable modules adaptable to the curricula of other medical schools. The specific aims of our program are 1) to enhance our existing basic science problem-based Biomedical Problems Program with respect to CVD prevention through development of additional curriculum in nutrition/diet/exercise and at-risk subpopulations; 2) to integrate into our Clinical Skills Program objectives for medical history taking, conducting patient exams, diet/lifestyle counseling and referrals to appropriate allied healthcare professionals that are specific to CVD prevention; 3) to enhance CVD components in the Community Science population-based medicine curriculum, stressing the health-field concept model, community needs assessment, evidence-based medicine and primary care issues in rural and medically underserved populations; 4) to enhance the CVD prevention and patient management component in existing 3rd- and 4th-y clinical clerkships with respect to nutrition/diet/exercise and socioeconomic issues, behavior modification and networking with allied health professionals; and 5) to integrate a nutrition/behavior change component into Graduate Residency Training in CVD prevention.

This article reviews some of the potential obstacles associated with performing research during space flight and offers brief descriptions of current and previous space research platforms and ground-based analogs, including those for human, animal, and cell-based research. This review is intended to highlight the main issues of space flight research analogs and leave the specifics for each physiologic system for the other papers in this section.

Insulin secretion and sensitivity in space flight: diabetogenic effects.

Nearly three decades of space flight research have suggested that there are subclinical diabetogenic changes that occur in microgravity. Alterations in insulin secretion, insulin sensitivity, glucose tolerance, and metabolism of protein and amino acids support the hypothesis that insulin plays an essential role in the maintenance of muscle mass in extended-duration space flight. Experiments in flight and after flight and ground-based bedrest studies have associated microgravity and its experimental paradigms with manifestations similar to those of diabetes, physical inactivity, and aging.
