Exploring the Interplay between Fatty Acids, Inflammation, and Type 2 Diabetes.

Around 285 million people worldwide currently have type 2 diabetes and it is projected that this number will be surpassed by 2030. Therefore, it is of the utmost importance to enhance our comprehension of the disease's development. The regulation of diet, obesity, and inflammation in type 2 diabetes is believed to play a crucial role in enhancing insulin sensitivity and reducing the risk of onset diabetes.

Vital Dye Uptake of YO-PRO-1 and DASPEI Depends Upon Mechanoelectrical Transduction Function in Zebrafish Hair Cells.

Purpose: Vital dyes allow the visualization of cells in vivo without causing tissue damage, making them a useful tool for studying lateral line and inner ear hair cells in living zebrafish and other vertebrates. FM1-43, YO-PRO-1, and DASPEI are three vital dyes commonly used for hair cell visualization. While it has been established that FM1-43 enters hair cells of zebrafish and other organisms through the mechanoelectrical transduction (MET) channel, the mechanism of entry into hair cells for YO-PRO-1 and DASPEI has not been established despite widespread use.

Emissions from plastic incineration induce inflammation, oxidative stress, and impaired bioenergetics in primary human respiratory epithelial cells.

Inhalation exposure to plastic incineration emissions (PIEs) is a problem of increasing human relevance, as plastic production and waste creation have drastically increased since mainstream integration during the 20th century. We investigated the effects of PIEs on human nasal epithelial cells (HNECs) to understand if such exposures cause damage and dysfunction to respiratory epithelia. Primary HNECs from male and female donors were cultured at air-liquid interface (ALI), and 16HBE cells were cultured on coverslips.

A CTB-SARS-CoV-2-ACE-2 RBD Mucosal Vaccine Protects Against Coronavirus Infection.

Mucosal vaccines protect against respiratory virus infection by stimulating the production of IgA antibodies that protect against virus invasion of the mucosal epithelium. In this study, a novel protein subunit mucosal vaccine was constructed for protection against infection by the beta coronavirus SARS-CoV-2. The vaccine was assembled by linking a gene encoding the SARS-CoV-2 virus S1 angiotensin converting enzyme receptor binding domain (ACE-2-RBD) downstream from a DNA fragment encoding the cholera toxin B subunit (CTB), a mucosal adjuvant known to stimulate vaccine immunogenicity.

Racial disparities in satisfaction with maternal healthcare.

Objective: To determine if there is a racial disparity in satisfaction with maternal healthcare, and examine the quality of care mothers of color receive.

Methods: An online survey of women in the United States who had been pregnant at least once was conducted. The study received an exempt determination by our Institution's Review Board.

Reversible suppression of circadian-driven locomotor rhythms in mice using a gradual fragmentation of the day-night cycle.

Circadian rhythms are regulated by molecular clockwork and drive 24-h behaviors such as locomotor activity, which can be rendered non-functional through genetic knockouts of clock genes. Circadian rhythms are robust in constant darkness (DD) but are modulated to become exactly 24 h by the external day-night cycle. Whether ill-timed light and dark exposure can render circadian behaviors non-functional to the extent of genetic knockouts is less clear.

The involvement of CdhR in Porphyromonas gingivalis during nitric oxide stress.

Porphyromonas gingivalis, the causative agent of adult periodontitis, must gain resistance to frequent oxidative and nitric oxide (NO) stress attacks from immune cells in the periodontal pocket to survive. Previously, we found that, in the wild-type and under NO stress, the expression of PG1237 (CdhR), the gene encoding for a putative LuxR transcriptional regulator previously called community development and hemin regulator (CdhR), was upregulated 7.7-fold, and its adjacent gene PG1236 11.

Redox Reactions of Biologically Active Molecules upon Cold Atmospheric Pressure Plasma Treatment of Aqueous Solutions.

Cold atmospheric pressure plasma (CAPP) is widely used in medicine for the treatment of diseases and disinfection of bio-tissues due to its antibacterial, antiviral, and antifungal properties. In agriculture, CAPP accelerates the imbibition and germination of seeds and significantly increases plant productivity. Plasma is also used to fix molecular nitrogen.

Draft Genome Sequences of sp. Strains Isolated from Stranded Septic Bottlenose Dolphins in Alabama, USA.

We report the genome sequences of two isolates from fatal cases of sepsis in bottlenose dolphins (Tursiops truncatus). The genomes were found to be most closely related to Erysipelothrix rhusiopathiae and Erysipelothrix piscisicarius. This information expands our knowledge of the genetic characteristics of this pathogen, which can affect free-ranging marine mammals.

Fragmented day-night cycle induces reduced light avoidance, excessive weight gain during early development, and binge-like eating during adulthood in mice.

Fragmented day-night (FDN) cycles are environments in which multiple periods of light and dark alternate across a 24 h period. Exposure to FDN cycles disrupts circadian rhythms, resulting in period lengthening and alterations to mood in mice. A constant light environment, which also induces period lengthening, is linked to mood and metabolic disturbances and disruption to the development of the circadian clock.

Examining the relationship between self-reported lifetime cancer diagnosis and nativity: findings from the National Health and Nutrition Examination Survey (NHANES) 2011-2018.

Purpose: Cancer incidence in the USA remains higher among certain groups, regions, and communities, and there are variations based on nativity. Research has primarily focused on specific groups and types of cancer. This study expands on previous studies to explore the relationship between country of birth (nativity) and all cancer site incidences among USA and foreign-born residents using a nationally representative sample.

Resilience, Emotional Intelligence, and Occupational Performance in Family Members Who Are the Caretakers of Patients with Dementia in Spain: A Cross-Sectional, Analytical, and Descriptive Study.

Background: The concern in the scientific community for the study of people with dementia and their families is comprehensible, especially the importance of knowing the effects that caring for the patient has on their family dynamic, paying special attention to the main caregiver. The objective of this study was to analyze the relationship of resilience and emotional intelligence with functional performance in the main caregivers of people with dementia in Spain according to the phase of the disease.

Methods: A cross-sectional, descriptive, and analytical study was carried out.

The Sugars in Alcohol Cocktails Matter.

While sugar consumption and alcohol drinking have traditionally been studied by different basic science fields, most commercially available flavored alcoholic beverages are sweetened with some kind of sugar. The prevailing view is that these sugars potentiate drinking by making the alcohol taste better, particularly for adolescents, overlooking that some central nervous system circuits implicated in alcohol drinking are also sensitive to brain penetrant sugars like glucose. In this Viewpoint, we highlight the need for basic researchers to carefully consider how the sugars mixed with alcoholic beverages may impact the neurochemical and biological mechanisms influencing alcohol drinking and the development of alcohol use disorder.

The Relationship between Differentiation of Self and Psychological Adjustment to Separation.

Many individuals suffer negative mental health consequences such as anxiety and depression following separation from a romantic partner and/or co-parenting conflict due to divorce. Consequently, treating the psychological aftermath of divorce and partner separation remains a predominant concern for mental health practitioners. According to family systems theory, high interdependence and low differentiation of self are associated with a lessened capacity for managing anxiety or adapting to stressful events since intense emotions may inhibit the ability to cope.

What Racism Has to Do with It: Understanding and Reducing Sexually Transmitted Diseases in Youth of Color.

Sexually transmitted diseases (STDs) are high in populations of color compared to Whites. High-risk sexual behaviors are widely viewed as the key contributors to the levels of STDs, especially in adolescents and young adults. This article situates the sexual risk behaviors of Black, Indigenous, and other young people of color within the framework of racism.

A Systematic Review of the Effects of Skin-to-Skin Contact on Biomarkers of Stress in Preterm Infants and Parents.

Background: Premature infants and their parents experience significant stress related to separation and lifesaving procedures. While evidence suggests that skin-to-skin contact (SSC) is a stress-reducing intervention for both neonates and parents, the mechanisms that underlie its efficacy are not well understood.

Objective: Purpose of this systematic review is to summarize the current state of knowledge on changes in biomarkers (ie, oxytocin [OT], cortisol, hypoxanthine, xanthine, uric acid, and allantoin), associated with SSC in premature infants and parents, that may reflect physiologic responses to stress.

Cold atmospheric pressure He-plasma jet and plasma ball interactions with the Venus flytrap: Electrophysiology and side effects.

Cold atmospheric pressure radio frequency plasma (CAPP) can play an important role in agriculture, medicine, biophysical and bioelectrochemical applications, disinfection and sterilization, synthesis of different compounds, nitrogen fixation, and treatment of surfaces. Here we found that reactive oxygen and nitrogen species, UV-Vis photons, and high-frequency strong electromagnetic fields with an amplitude of a few kV produced by a cold plasma jet can interact with bio-tissue and damage it if the plasma treatment is long enough. The electrophysiological effects of CAPP treatment of bio-tissue and electrical signals transmission were measured in the Venus flytrap.

Falls Prevention and Quality of Life Improvement by Square Stepping Exercise in People with Parkinson's Disease: Project Report.

Parkinson's disease (PD) is a chronic neurodegenerative disorder that affects physical, psychological, and social quality of life. Square Stepping Exercise (SSE) is an effective balance training program to prevent falls and to stimulate cognitive function in the elderly; however, no study has analyzed the effect of SSE in people with PD. The main objective is to investigate whether the application of SSE is safe, applicable, and can improve balance, and is effective in preventing falls, improving cognitive and psychological aspects and thus maximize quality of life in people with PD.

Cyclic voltammetry of volatile memristors in the Venus flytrap: short-term memory.

Plants have sensory, short-term and long-term memory. Possible candidates for memory in plants are memristors; resistors with memory. Memristors have been found in seeds, plants, flowers and fruits.

Radio frequency plasma capacitor can increase rates of seeds imbibition, germination, and radicle growth.

Radio frequency capacitors can be used to accelerate seed imbibition, germination, increase the growth of plants seedlings, poration and corrugation of the bio-tissue surfaces without the side effects of RONS generated by cold plasma jets. Atomic force microscope data show that the plasma lamp produced morphological changes in the seed coat. Magnetic resonance imaging studies showed the acceleration of water uptake in seeds treated with radio frequency capacitors of plasma lamps.

Light Has Diverse Spatiotemporal Molecular Changes in the Mouse Suprachiasmatic Nucleus.

To be physiologically relevant, the period of the central circadian pacemaker, located in the suprachiasmatic nucleus (SCN), has to match the solar day in a process known as circadian photoentrainment. However, little is known about the spatiotemporal molecular changes that occur in the SCN in response to light. In this study, we sought to systematically characterize the circadian and light effects on activity-dependent markers of transcriptional (cFos), translational (pS6), and epigenetic (pH3) activities in the mouse SCN.

Underground electrotonic signal transmission between plants.

Plants can communicate with other plants using wireless pathways above and underground. Some examples of these underground communication pathways are: (1) mycorrhizal networks in the soil; (2) the plants' rhizosphere; (3) acoustic communication; (4) naturally grafting of roots of the same species; (5) signaling chemicals exchange between roots of plants; and (6) electrical signal transmission between plants through the soil. To avoid the possibility of communication between plants using mechanisms (1)-(5), soils in both pots with plants can be connected by Ag/AgCl or platinum wires.
