Time-restricted feeding reduces cardiovascular disease risk in obese mice.

Disrupted feeding and fasting cycles as well as chronic high fat diet (HFD)-induced obesity are associated with cardiovascular disease risk factors. We designed studies that determined whether two weeks of time-restricted feeding (TRF) intervention in mice fed a chronic HFD would reduce cardiovascular disease risk factors. Mice were fed a normal diet (ND; 10% fat) ad libitum or HFD (45% fat) for 18 weeks ad libitum to establish diet-induced obesity.

Aryl Hydrocarbon Receptor Activation Promotes Effector CD4+ T Cell Homeostasis and Restrains Salt-sensitive Hypertension.

Excess dietary salt and salt-sensitivity contribute to cardiovascular disease. Distinct T cell phenotypic responses to high salt and hypertension as well as influences from environmental cues are not well understood. The aryl hydrocarbon receptor (AhR) is activated by dietary ligands, promoting T cell and systemic homeostasis.

Skin and Soft Tissue Infection Complicated by Sepsis in an Immunocompromised Patient: A Rare Case Report.

Physicians should consider non-O1, non-O139 (NOVC) in the differential diagnosis of cellulitis complicated by sepsis, especially in immunocompromised patients when potential exposure exists. Due to the pathogen's potential for severe infections and rising incidence from environmental changes, we emphasize the need for increased awareness and appropriate treatment guidelines.

To do or not to do: Large-dose steroid treatment for severe vision loss secondary to compressive inflammatory optic neuropathy in the setting of invasive fungal sinusitis.

Purpose: Invasive fungal sinusitis (IFS) is associated with high rates of morbidity and mortality and often presents with orbital apex syndrome. Prompt diagnosis and management are crucial to prevent irreversible visual loss. We report a case of an immunosuppressed patient with rapidly progressive severe visual loss associated with frontal lobe cerebritis and leptomeningitis related to IFS, causing an adjacent compressive inflammatory optic neuropathy, which was treated successfully by large-dose corticosteroids.

Fat Embolism Does Not Alter Cardiac Structure or Induce Pathological Changes in a Rat Model.

Introduction: Fat embolism (FE) encompasses conditions in which fatty substance becomes embedded in a tissue/organ. Fat emboli most commonly affect the lungs in a trauma setting. This can lead to both significant pathology locally and systemically including changes in structure, inflammatory response, activation of the renin-angiotensin system, and subsequent hypoxia.

A Diagnostic Stewardship Intervention to Improve Utilization of 1,3 β-D-Glucan Testing at a Single Academic Center: Five-Year Experience.

Background: (1,3)- β-D-glucan (BDG) testing is one of the noninvasive tests to aid diagnosis of invasive fungal infections (IFIs). The study results have been heterogenous, and diagnostic performance varies depending on the risks for IFI. Thus, it is important to select appropriate patients for BDG testing to prevent false-positive results.

Ocular Dirofilariasis: A Clinicopathologic Case Series and Literature Review.

Purpose: Ocular dirofilariasis is an uncommon zoonotic infection that is usually associated with a carnivore host. In this case series and literature review, we investigate the clinical presentation, management, and histopathology of ocular dirofilariasis.

Methods: The database at the Florida Lions Ocular Pathology Laboratory was searched for surgical specimens at the Bascom Palmer Eye Institute under approval of the Institutional Review Board.

Permissive omicron breakthrough infections in individuals with binding or neutralizing antibodies to ancestral SARS-CoV-2.

Background: Breakthrough infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant (B.1.1.

Early life stress induces dysregulation of the heme pathway in adult mice.

Early life stress (ELS) is associated with cardiovascular disease (CVD) risk in adulthood, but the underlying vascular mechanisms are poorly understood. Increased hemoglobin and heme have recently been implicated to mediate endothelial dysfunction in several vascular diseases. Chronic physiological stress is associated with alterations in the heme pathway that have been well-described in the literature.

Early life stress in mice alters gut microbiota independent of maternal microbiota inheritance.

Exposure to early life stress (ELS) is associated with a greater risk of chronic disease development including depression and cardiovascular disease. Altered gut microbiota has been linked to both depression and cardiovascular disease in mice and humans. Rodent models of early life neglect are used to characterize the mechanistic links between early life stress (ELS) and the risk of disease later in life.

Timing of Food Intake Drives the Circadian Rhythm of Blood Pressure.

Timing of food intake has become a critical factor in determining overall cardiometabolic health. We hypothesized that timing of food intake entrains circadian rhythms of blood pressure (BP) and renal excretion in mice. Male C57BL/6J mice were fed ad libitum or reverse feeding (RF) where food was available at all times of day or only available during the 12-h lights-on period, respectively.

Fluid-electrolyte homeostasis requires histone deacetylase function.

Histone deacetylase (HDAC) enzymes regulate transcription through epigenetic modification of chromatin structure, but their specific functions in the kidney remain elusive. We discovered that the human kidney expresses class I HDACs. Kidney medulla-specific inhibition of class I HDACs in the rat during high-salt feeding results in hypertension, polyuria, hypokalemia, and nitric oxide deficiency.

Primary Intestinal Lymphangiectasia Causing Intussusception and Small Bowel Obstruction.

Abdominal lymphangiectasia is a rare disease manifestation with a variety of anatomic locations and clinical presentations. The gastrointestinal tract may be affected, and lymphangiectasia originating in the wall of the intestine has rarely been described. We present a case of primary small bowel lymphangiectasia causing intussusception in a 30-year-old woman who presented with emesis and gastrointestinal bleeding.

Visualization of the Stimuli-responsive Surface Behavior of Functionalized Wood Material by Chemical Force Microscopy.

The hierarchical and porous wood structure provides a stable scaffold to design functionalized lignocellulosic materials with extended properties by chemical modification techniques. However, proper nanoscale characterization methods for these novel materials are needed to confirm the presence of the added functionality and to locate the introduced functional groups with high spatial resolution. Chemical force microscopy is a suitable characterization method to distinguish chemical surface characteristics by scanning the samples surface with a functionalized tip.

Structural change and economic growth in the British economy before the Industrial Revolution, 1500-1800.

Structural transformation is a key indicator of economic development. We present the first time series of male labour sectoral shares for England and Wales before 1800, using a large sample of probate and apprenticeship data to produce national and county-level estimates. England experienced a rapid decline in the share of workers in agriculture between the early seventeenth and the beginning of the eighteenth centuries, associated with rising agricultural and especially industrial productivity; Wales saw few changes.

Adhesion properties of regenerated lignocellulosic fibres towards poly(lactic acid) microspheres assessed by colloidal probe technique.

In the field of polymer reinforcement, it is important to understand the interactions involved between the polymer matrix and the reinforcing component. This paper is a contribution to the fundamental understanding of the adhesion mechanisms involved in natural fibre reinforced composites. We report on the use of the colloidal probe technique for the assessment of the adhesion behaviour between poly(lactic acid) microspheres and embedded cross-sections of regenerated lignocellulosic fibres.

Submicron hierarchy of cellulose nanofibril films with etherified hemicelluloses.

The lack of simple differentiation of all-polysaccharide-film components in nanoscale hinders unveiling their structure-property dependency. Submicron hierarchy of films of cellulose nanofibrils (CNFs) and carbohydrate-based additives was revealed via visualization of the components by their differentiating adhesion to an Atomic Force Microscope (AFM) tip. The differentiation of the film components revealed that distribution of hydroxypropylated hemicellulose in the CNF matrix could be tuned by addition of a plasticizer.

Pulp Fines-Characterization, Sheet Formation, and Comparison to Microfibrillated Cellulose.

In the pulp and paper industry different types of pulp or fiber fines are generated during the pulping (primary fines, mechanical fines), and/or the refining process (secondary fines). Besides fibers, these cellulosic microparticles are a further component of the paper network. Fines, which are defined as the fraction of pulp that is able to pass through a mesh screen or a perforated plate having a hole diameter of 76 μm, are known to influence the properties of the final paper product.

Nanopaper Properties and Adhesive Performance of Microfibrillated Cellulose from Different (Ligno-)Cellulosic Raw Materials.

The self-adhesive potential of nanocellulose from aqueous cellulosic suspensions is of interest with regard to a potential replacement of synthetic adhesives. In order to evaluate the performance of microfibrillated cellulose from different (ligno-)cellulosic raw materials for this purpose, softwood and hardwood powder were fibrillated and compared to sugar beet pulp as a representative non-wood cellulose resource, and conventional microfibrillated cellulose produced from bleached pulp. An alkali pre-treatment of woody and sugar beet raw materials enhanced the degree of fibrillation achieved, same as TEMPO-mediated oxidation of microfibrillated cellulose.

Medical Practice, Urban Politics and Patronage: The London 'Commonalty' of Physicians and Surgeons of the 1420s.

Medical practice in fifteenth-century England is often seen as suffering from the low status and unregulated practice of which Thomas Linacre later complained. Unlike in many European cities, the provision of physic was uncontrolled, and while urban guilds oversaw surgery as a manual art, no comprehensive system of medical organisation or regulation existed. However, in a remarkable episode of the 1420s, a group of university-trained physicians and elite surgeons associated with Humphrey, Duke of Gloucester, briefly established just such a system.

Chronic pain treatment with opioid analgesics: benefits versus harms of long-term therapy.

Chronic non-cancer pain (CNCP) is a disabling chronic condition with a high prevalence rate around the world. Opioids are routinely prescribed for treatment of chronic pain (CP). In the past two decades there has been a massive increase in the number of opioid prescriptions, prescribed daily opioid doses and overall opioid availability.

Rationally synthesized two-dimensional polymers.

Synthetic polymers exhibit diverse and useful properties and influence most aspects of modern life. Many polymerization methods provide linear or branched macromolecules, frequently with outstanding functional-group tolerance and molecular weight control. In contrast, extending polymerization strategies to two-dimensional periodic structures is in its infancy, and successful examples have emerged only recently through molecular framework, surface science and crystal engineering approaches.

An update of evaluation of intravenous sedation on diagnostic spinal injection procedures.

Background: Intravenous (IV) sedation analgesia is often employed in patients with chronic spinal pain undergoing diagnostic spinal injection procedures. The drugs used for intravenous sedation analgesia produce varying degrees of sedation, amnesia, anxiolysis, muscle relaxation, and analgesia. The very nature of these pharmacologic effects in altering the patient's level of consciousness, awareness, or response to a particular diagnostic stimulus invokes a sense of uncertainty about the results or response obtained from the diagnostic procedure.
