This review examines microbial polysaccharides' properties relevant to their use in packaging and pharmaceutical applications. Microbial polysaccharides are produced by enzymes found in the cell walls of microbes. Xanthan gum, curdlan gum, pullulan, and bacterial cellulose are high-molecular-weight substances consisting of sugar residues linked by glycoside bonds.

BMP receptor 2 inhibition regulates mitochondrial bioenergetics to induce synergistic cell death with BCL-2 inhibitors in leukemia and NSLC cells.

Background: Bone morphogenetic protein (BMP) signaling cascade is a phylogenetically conserved stem cell regulator that is aberrantly expressed in non-small cell lung cancer (NSLC) and leukemias. BMP signaling negatively regulates mitochondrial bioenergetics in lung cancer cells. The impact of inhibiting BMP signaling on mitochondrial bioenergetics and the effect this has on the survival of NSLC and leukemia cells are not known.

Isoniazid urine spectrophotometry for prediction of serum pharmacokinetics in adults with TB.

Background: Isoniazid (INH) is an important drug in many TB regimens, and unfavorable treatment outcomes can be caused by suboptimal pharmacokinetics. Dose adjustment can be personalized by measuring peak serum concentrations; however, the process involves cold-chain preservation and laboratory techniques such as liquid chromatography (LC)/mass spectrometry (MS), which are unavailable in many high-burden settings. Urine spectrophotometry could provide a low-cost alternative with simple sampling and quantification methods.

Concomitant assessment of PD-1 and CD56 expression identifies subsets of resting cord blood Vδ2 T cells with disparate cytotoxic potential.

Vγ9Vδ2 T lymphocytes are programmed for broad antimicrobial responses with rapid production of Th1 cytokines even before birth, and thus thought to play key roles against pathogens in infants. The process regulating Vδ2 cell acquisition of cytotoxic potential shortly after birth remains understudied. We observed that perforin production in cord blood Vδ2 cells correlates with phenotypes defined by the concomitant assessment of PD-1 and CD56.

Geroscience: Aging and Oral Health Research.

Research in aging has significantly advanced; scientists are now able to identify interventions that slow the biologic aging processes (i.e., the "hallmarks of aging"), thus delaying the onset and progression of multiple diseases, including oral conditions.

Enhancing Self-care Among Oral Cancer Survivors: Protocol for the Empowered Survivor Trial.

Background: Survivors of oral cavity and oropharyngeal cancer frequently experience difficulties in swallowing; tasting; speaking; chewing; and maintaining comfortable movements of the head, neck, and shoulder. Engagement in regular self-care can reduce further loss of function and mitigate late effects. Despite the substantial self-care requirements, there are no empirically based interventions to enhance the skills and confidence of these survivors in managing their ongoing care.

Associations of maternal plasma and umbilical cord plasma metabolomics profiles with birth anthropometric measures.

Background: The metabolomics profiles of maternal plasma during pregnancy and cord plasma at birth might influence fetal growth and birth anthropometry. The objective was to examine how maternal plasma and umbilical cord plasma metabolites are associated with newborn anthropometric measures, a known predictor of future health outcomes.

Methods: Pregnant women between 24 and 28 weeks of gestation were recruited as part of a prospective cohort study.

PolyQ-Expanded Mutant Huntingtin Forms Inclusion Body Following Transient Cold Shock in a Two-Step Aggregation Mechanism.

Age-dependent formation of insoluble protein aggregates is a hallmark of many neurodegenerative diseases. We are interested in the cell chemistry that drives the aggregation of polyQ-expanded mutant Huntingtin (mHtt) protein into insoluble inclusion bodies (IBs). Using an inducible cell model of Huntington's disease, we show that a transient cold shock (CS) at 4 °C followed by recovery incubation at temperatures of 25-37 °C strongly and rapidly induces the compaction of diffuse polyQ-expanded Huntingtin-enhanced green fluorescent protein chimera protein (mHtt) into round, micron size, cytosolic IBs.

Tango of dual nanoparticles: Interplays between exosomes and nanomedicine.

Exosomes are lipid bilayer vesicles released from cells as a mechanism of intracellular communication. Containing information molecules of their parental cells and inclining to fuse with targeted cells, exosomes are valuable in disease diagnosis and drug delivery. The realization of their clinic applications still faces difficulties, such as lacking technologies for fast purification and functional reading.

Risk factors of long-term alopecia after pulsed-dye laser treatment for infantile scalp hemangiomas: A retrospective study.

Pulsed-dye laser (PDL), as an effective and frequently-used treatment modality for infantile hemangiomas (IH), could render patients at risk of developing long-term alopecia. Data on alopecia caused by PDL treatment remain scant and the contributing factors are not clear. Our objective was to identify the risk factors associated with long-term alopecia resulting from PDL treatment for scalp IH.

Pediatric firearm injury trends in the United States: A national trauma data bank (NTDB) analysis.

Aim Of Study: Firearm injuries are the second leading cause of injury-related death in the USA in children less than 18. We compared overall and intent-specific firearm hospitalizations across age group and race to understand recent trends.

Methods: A retrospective cohort of 20,083 children from the national trauma data bank involved in incidences of firearm discharges from 2013 to 2017 was divided by race, discharge intent, gun type, and four age groups: infants (ages 0-2), toddlers (3-6), children (7-12), and adolescents (13-18).

Tumor suppressor p53 cross-talks with TRIM family proteins.

p53 is a key tumor suppressor. As a transcription factor, p53 accumulates in cells in response to various stress signals and selectively transcribes its target genes to regulate a wide variety of cellular stress responses to exert its function in tumor suppression. In addition to tumor suppression, p53 is also involved in many other physiological and pathological processes, e.

Interspecies Recombination Has Driven the Macroevolution of Cassava Mosaic Begomoviruses.

Begomoviruses (family , genus ) significantly hamper crop production and threaten food security around the world. The frequent emergence of new begomovirus genotypes is facilitated by high mutation frequencies and the propensity to recombine and reassort. Homologous recombination has been especially implicated in the emergence of novel cassava mosaic begomovirus (CMB) genotypes, which cause cassava mosaic disease (CMD).

Regional variation in gastroschisis: a nationwide database review of demographics and outcomes.

Extracellular vesicles in the context of Mycobacterium tuberculosis infection.

The production of extracellular vesicles (EVs) has emerged as an important process in bacterial biology and host-pathogen interactions. Like many other bacteria, mycobacteria, including Mycobacterium tuberculosis (Mtb), the causative agent of human tuberculosis (TB), produces EVs in vitro and in vivo. These membrane-enclosed nanoparticles enable Mtb to secrete hydrophobic molecules, proteins, lipids and glycolipids in a concentrated and protected manner and engage in remote interactions with the host.

The Interplay Between Tumor Suppressor p53 and Hypoxia Signaling Pathways in Cancer.

Hypoxia is a hallmark of solid tumors and plays a critical role in different steps of tumor progression, including proliferation, survival, angiogenesis, metastasis, metabolic reprogramming, and stemness of cancer cells. Activation of the hypoxia-inducible factor (HIF) signaling plays a critical role in regulating hypoxic responses in tumors. As a key tumor suppressor and transcription factor, p53 responds to a wide variety of stress signals, including hypoxia, and selectively transcribes its target genes to regulate various cellular responses to exert its function in tumor suppression.

Study of social disparities in pediatric laparoscopic appendectomy outcomes and cost.

Purpose: There is an increasing focus on racial and social disparities in health care. There have been several studies that have documented disparities in outcome between racial groups in the adult literature. Not much is known about disparities in outcomes after surgical procedures in children.

The age pattern of the male-to-female ratio in mortality from COVID-19 mirrors that of cardiovascular disease in the general population.

Males are at a higher risk of dying from COVID-19 than females. Older age and cardiovascular disease are also associated with COVID-19 mortality. To better understand how age and sex interact contributing to COVID-19 mortality, we stratified the male-to-female (sex) ratios in mortality by age group.

Pediatric Nonaccidental Trauma: Experience at a Level 1 Trauma Center.

Introduction: Pediatric nonaccidental trauma (NAT) is difficult to diagnose. Several isolated injuries in NAT could happen in the setting of accidental trauma (AT), and having a high index of suspicion is important to correctly identify abuse. NAT has a significant mortality rate if the sentinel event is not adequately diagnosed, and the infant is not separated from the perpetrator.

The emerging role of leukemia inhibitory factor in cancer and therapy.

Leukemia inhibitory factor (LIF) is a multi-functional cytokine of the interleukin-6 (IL-6) superfamily. Initially identified as a factor that inhibits the proliferation of murine myeloid leukemia cells, LIF displays a wide variety of important functions in a cell-, tissue- and context-dependent manner in many physiological and pathological processes, including regulating cell proliferation, pluripotent stem cell self-renewal, tissue/organ development and regeneration, neurogenesis and neural regeneration, maternal reproduction, inflammation, infection, immune response, and metabolism. Emerging evidence has shown that LIF plays an important but complex role in human cancers; while LIF displays a tumor suppressive function in some types of cancers, including leukemia, LIF is overexpressed and exerts an oncogenic function in many more types of cancers.
