BACKGROUND: Previous studies have shown that early life nutrition can modulate the development of white adipose tissue and thereby affect the risk on obesity and metabolic disease later in life. For instance, postnatal feeding with a concept infant milk formula with large, phospholipid coated lipid droplets (Concept, Nuturis®), resulted in reduced adiposity in adult mice. The present study investigated whether differences in cell energy metabolism, using markers of mitochondrial content and capacity, may contribute to the observed effects...

The purpose of this study was to evaluate various types of meniscus scaffolds that mimic the meniscus structure, and to establish a novel cell-free meniscus scaffold with polyglycolic acid or poly-l-lactic acid. Four types of scaffolds were implanted into Japanese white rabbits: poly-l-lactic acid sponge poly-l-lactic acid, PGA-coated PLLA sponge, PGA lamination, and film-coated PGA lamination. Samples were harvested at 8 and 12 weeks after implantation, and a compression stress test was performed. The meniscus size and Ishida scores were evaluated for regenerated tissue...

Arterial hypertension has a high prevalence and is a major risk factor for the development of cardiovascular diseases. It is a major contributor to worldwide morbidity and mortality and hence poses a huge socioeconomic burden. Despite great progress in perception, diagnosis and treatment of hypertension, blood pressure control is inadequate in less than half of the hypertensive patients (<140/90 mm Hg). The diagnosis of arterial hypertension starts in most patients with the conventional office blood pressure measurement...

BACKGROUND: Despite the fact that medical schools spend a considerable effort to rate clinical instructors, there is limited evidence regarding the effect of physical characteristics on instructor ratings. White coats have been shown to alter patients' perceptions of physicians although it has not been determined if preceptors who wear white coats are rated differently than their colleagues. METHODS: Second year medical students were administered a questionnaire with four clinical scenarios depicting medical errors accompanied by a picture of a physician of different sexes and ethnicities...

Sickle cell disease (SCD) is a life-threatening genetic condition. Patients suffer from chronic systemic and cerebral vascular disease that leads to early and cumulative neurological damage. Few studies have quantified the effects of this disease on brain morphometry and even fewer efforts have been devoted to older patients despite the progressive nature of the disease. This study quantifies global and regional brain volumes in adolescent and young adult patients with SCD and racially matched controls with the aim of distinguishing between age related changes associated with normal brain maturation and damage from sickle cell disease...

In medicine, it is critical that clinicians demonstrate both empathy (perceived as warmth) and competence. Perceptions of these qualities are often intuitive and are based on nonverbal behavior. Emphasizing both warmth and competence may prove problematic, however, because there is evidence that they are inversely related in other settings. We hypothesize that perceptions of physician competence will instead be positively correlated with perceptions of physician warmth and empathy, potentially due to changing conceptions of the physician's role...

Haze formation is a significant problem for the wine industry. A novel technology for the rapid, selective, magnetic removal of pathogenesis-related proteins from wine was developed. The pathogenesis-related proteins in nine different white wines were selectively captured and removed by acrylic acid plasma-coated magnetic nanoparticles. Treated white wines were analyzed for protein and phenolic content to assess the performance of the functionalized magnetic nanoparticles. The analysis showed that the acrylic acid coated magnetic nanoparticles effectively removed proteins and did not significantly change the phenolic composition of the wines...

BACKGROUND: Interarm differences (IADs) ≥10 mm Hg in systolic blood pressure (BP) are associated with greater incidence of cardiovascular disease. The effect of ethnicity and the white coat effect (WCE) on significant systolic IADs (ssIADs) are not well understood. METHODS: Differences in BP by ethnicity for different methods of BP measurement were examined in 770 people (300 White British, 241 South Asian, 229 African-Caribbean). Repeated clinic measurements were obtained simultaneously in the right and left arm using 2 BPTru monitors and comparisons made between the first reading, mean of second and third and mean of second to sixth readings for patients with, and without known hypertension...

REVIEW
Relu Cernes, Reuven Zimlichman
PURPOSE OF REVIEW: Hypertension remains to be a major contributor to global morbidity and mortality. Despite a plethora of pharmacological options available, an abundance of patients have uncontrolled blood pressure thus creating the need for additional strategies, including non-pharmacologic approaches. In this review, we discuss the antihypertensive effect of slow and deep respiration by increasing baroreflex sensitivity. RECENT FINDINGS: Asking patients to carry out paced breathing sessions unaccompanied by a personal coach or unaided by a device may be unfeasible...

BACKGROUND: Leukoencephalopathy with calcifications and cysts is a rare, autosomal recessive cerebral microangiopathy that causes progressive white matter disease, calcifications, and cysts within the brain. It is typically associated with slowly progressive psychomotor regression, seizures, and movement disorders. Although leukoencephalopathy with calcifications and cysts affects only the central nervous system, it demonstrates remarkable neuropathologic and radiologic overlap with Coats plus, a disorder of small vessels of the brain, eyes, gastrointestinal tract, and bone...

OBJECTIVES: Test if older people's memory assessment may be impacted by a medical environment and if memory self-efficacy (MSE) will moderate this effect. METHODS: We evaluated memory performance and MSE in 27 older adults in two different settings: a (control) university research environment, or a (proxy-medical) neuropsychological examination environment. RESULTS: The results showed a MSE × environment interaction effect on story-recall performance, with older people with low MSE performing less well in the proxy-medical situation than in the control situation and with elders with high MSE performing better in the proxy-medical situation than in the control situation...

A novel fibrous mesoporous silica nanoparticles (fSiO2) stationary phase grafted with polymer (Poly (2-(dimethylamino) ethyl methacrylate) (PDMAEMA) was developed for open tubular capillary electrochromatography (OT-CEC). The preparation procedure included synthesizing fSiO2 through biphase stratification approach, removing the surfactants, silanization and in situ graft polymerization with monomers via atom transfer radical polymerization (ATRP). Subsequently, PDMAEMA-modified mesoporous silica nanoparticles (P-fSiO2)/ethanol solution was immobilized onto the inner surface of the pretreated capillary and functionalized with octadecylsilane to fabricate the open-tubular column...

An iron-doped Y-cut lithium niobate (Fe:LN) slab was coated with indium-tin-oxide (ITO) thin films by magnetron sputtering. The electron confinement in a sub-nanometer region at ITO/LN interfaces is resulted from electric screening effect. Consequently, the local plasma frequency in the sub-nanometer metallic-like layer is shifted to the UV regime. This makes it possible to excite surface plasmon polaritons (SPPs) in the visible region with photorefractive phase gratings in the LN slab and to transport SPPs much energy-efficiently...

Here we report a previously undescribed coat color phenotype in Holstein cattle. Larson Blue Holsteins, located on a dairy in south Florida, exhibit a coloration pattern that is similar to that of black and white or red and white Holsteins except that, instead of being black or red, darker regions of the body vary in color from gray to taupe. The Larson Blue phenotype was readily apparent in young calves. The phenotype is not due to inheritance of known mutations causing coat color variation in cattle, including dominant red, Telstar, silver color dilutor, or Dun color...

A doctor's attire is vital for both a positive first impression and the overall healthcare experience of patients. We attempted to understand patients' and doctors' perceptions and preferences regarding six types of dress codes used by doctors in different situations and locations. A total of 87 patients and 46 doctors participated in the study. Separate sets of questionnaires, that included four demographic questions and 14 survey questions, were given to the patient and doctor groups. Most patients preferred doctors dressed formally in white coats irrespective of scenarios or locations whereas majority of doctors preferred formal attire without white coats...

Chronic hyperplastic candidiasis (CHC), earlier known as candidal leukoplakia, is a variant of oral candidiasis that classically presents as a white patch on the commissures of the oral mucosa and it is mostly caused by Candida albicans. Clinically, the lesions are usually asymptomatic and regress after appropriate antifungal therapy and correction of the underlying cause. If the lesions are untreated, a small portion may develop dysplasia and later progress into carcinoma. The purpose of this article is to report a case of CHC in a 57-year-old male patient with a significant smoking habit, who presented with a thick, nonscrapable, brownish-white coating on the dorsum of the tongue for 9 years...

Highly efficient blue-emitting CdSe-derived core/shell gradient alloy quantum dots (CSGA QDs) with photoluminescence quantum yield (PL QY) of ca. 90% have been synthesized through a facile "one-pot" approach. CdSe nuclei are initially formed as core and gradient alloy shells such as CdSexS1-x/ZnSeyS1-y simultaneously encapsulate the preformed CdSe core in an energy-gradient fashion eventually followed by coating with ZnS shells due to the faster precursor reaction kinetics of Cd and Se compared to analog of Zn and S...

There is arguably no less understood or more intriguing problem in hypertension that the "white coat" condition, the standard concept of which is significantly blood pressure reading obtained by medical personnel of authoritative standing than that obtained by more junior and less authoritative personnel and by the patients themselves. Using hospital-initiated ambulatory blood pressure monitoring, the while effect manifests as initial and ending pressure elevations, and, in treated patients, a low daytime profile...

This communication describes the inhibitory effect of Morin on the fibrillation of Hen Egg White Lysozyme (HEWL), a generic amyloid-forming model protein. This effect was dose-dependent and stronger than other small molecules we have tested previously. Spectrofluorometric and computational studies support a model suggesting that Morin inhibits amyloid fibril formation of HEWL by binding to the aggregation prone cleft region of the β-domain of HEWL, thereby stabilizing the molecule in its native-like state...
