Selection and adaptive introgression guided the complex evolutionary history of the European common bean.

Domesticated crops have been disseminated by humans over vast geographic areas. Common bean (Phaseolus vulgaris L.) was introduced in Europe after 1492.

Oral Intake of Enzymatically Decomposed AP Collagen Peptides Improves Skin Moisture and Ceramide and Natural Moisturizing Factor Contents in the Stratum Corneum.

The stratum corneum (SC) is the outermost layer of the epidermis and plays an important role in maintaining skin moisture and protecting the skin from the external environment. Ceramide and natural moisturizing factor (NMF) are the major SC components that maintain skin moisture. In this study, we investigated whether the oral intake of enzymatically decomposed AP collagen peptides (APCPs) can improve skin moisture and barrier function by assessing changes in the ceramide and NMF contents in the SC after APCP ingestion with the aim to develop a skin functional food.

Synergistic effects of using novel home-use 660- and 850-nm light-emitting diode mask in combination with hyaluronic acid ampoule on photoaged Asian skin: A prospective, controlled study.

Background: Recently, light-emitting diode (LED) devices are among those mostly preferred for esthetic application because they improve the appearance of photoaged skin characterized by wrinkles, sagginess, pigmented lesions, and others. In addition, the use of hyaluronic acid (HA) for skin rejuvenation is already well proven.

Aims: This study aims to evaluate the synergistic effects of using home-use LED mask device with HA ampoule.

The genome sequence of segmental allotetraploid peanut Arachis hypogaea.

Like many other crops, the cultivated peanut (Arachis hypogaea L.) is of hybrid origin and has a polyploid genome that contains essentially complete sets of chromosomes from two ancestral species. Here we report the genome sequence of peanut and show that after its polyploid origin, the genome has evolved through mobile-element activity, deletions and by the flow of genetic information between corresponding ancestral chromosomes (that is, homeologous recombination).

Integrating Registered Dietitian Nutritionists Into Primary Care Practices to Work With Children With Overweight.

Despite increased reimbursement for registered dietitian nutritionists (RDNs), few studies have assessed the potential of integrating them into primary care clinics to support pediatric weight management. To assess the feasibility and effectiveness of this approach, RDNs were introduced into 8 primary care practices in North Carolina. This mixed-methods study combined (1) interviews and focus groups with RDNs and clinic personnel, (2) comparison of change in body mass index (BMI) z-score in study practices to change in historical comparison groups, and (3) analysis of behavior and BMI change for RDN utilizers.

Transcriptomic Profiling of Soybean in Response to High-Intensity UV-B Irradiation Reveals Stress Defense Signaling.

The depletion of the ozone layer in the stratosphere has led to a dramatic spike in ultraviolet B (UV-B) intensity and increased UV-B light levels. The direct absorption of high-intensity UV-B induces complex abiotic stresses in plants, including excessive light exposure, heat, and dehydration. However, UV-B stress signaling mechanisms in plants including soybean ( [L.

The Relationship of Socioeconomic and Behavioral Risk Factors With Trends of Overweight in Korea.

Objectives: Previous studies have shown that overweight (including obesity) has increased significantly in Korea in recent decades. However, it remains unclear whether this change has been uniform among all Koreans and to what extent socioeconomic and behavioral factors have contributed to this increase.

Methods: Changes in overweight were estimated using data from the 1998, 2001, 2005, 2007-2009, and 2010-2012 Korea National Health and Nutrition Examination Survey (n=55 761).

Role of autophagy in the pathogenesis of amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a late-onset neurodegenerative disease characterized by the selective degeneration of upper and lower motor neurons associated with the abnormal aggregation of ubiquitinated proteins. The molecular mechanisms underlying the pathogenesis of ALS remain unclear, however. Autophagy is a major pathway for the elimination of protein aggregates and damaged organelles and therefore contributes to cellular homeostasis.

Iron accumulation promotes TACE-mediated TNF-α secretion and neurodegeneration in a mouse model of ALS.

Oxidative stress contributes to degeneration of motor neurons in patients with amyotrophic lateral sclerosis (ALS) as well as transgenic mice overexpressing ALS-associated human superoxide dismutase 1 (SOD1) mutants. However, the molecular mechanism by which the ALS-linked SOD1 mutants including SOD1(G93A) induce oxidative stress remains unclear. Here, we show that iron was accumulated in ventral motor neurons from SOD1(G93A)-transgenic mice even at 4 weeks of age, subsequently inducing oxidative stress.

Transcriptomic changes due to water deficit define a general soybean response and accession-specific pathways for drought avoidance.

Background: Among abiotic stresses, drought is the most common reducer of crop yields. The slow-wilting soybean genotype PI 416937 is somewhat robust to water deficit and has been used previously to map the trait in a bi-parental population. Since drought stress response is a complex biological process, whole genome transcriptome analysis was performed to obtain a deeper understanding of the drought response in soybean.

CIIA prevents SOD1(G93A)-induced cytotoxicity by blocking ASK1-mediated signaling.

Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease with higher selectivity in degeneration of motor neurons. However, the molecular mechanism by which the ALS-linked mutants of human superoxide dismutase 1 (SOD1) gene induce neurotoxicity remains obscure yet. Here, we show that depletion of CIIA expression by RNA interference (RNAi) promoted cytotoxicity caused by ALS-linked G93A mutant of the SOD1 gene.

Ischemic brain extract increases SDF-1 expression in astrocytes through the CXCR2/miR-223/miR-27b pathway.

Ischemic cerebral stroke is one of the leading global causes of mortality and morbidity. Ischemic preconditioning (IPC) refers to a sublethal ischemia and resulting in tolerance to subsequent severe ischemic injury. Although several pathways are reportedly involved in IPC-mediated neuroprotection, the functional role of astrocytes is not fully understood.

Cobalt chloride induces neuronal differentiation of human mesenchymal stem cells through upregulation of microRNA-124a.

Human mesenchymal stem cells (hMSCs) are known to have the capacity to differentiate into various cell types, including neurons. To examine our hypothesis that miRNA was involved in neuronal differentiation of hMSCs, CoCl2, a hypoxia-mimicking agent was used to induce neuronal differentiation, which was assessed by determining the expression of neuronal markers such as nestin and Tuj1. Treatment of hMSCs with CoCl2 led to increased expression of miR-124a, a neuron-specific miRNA.

Sequence-Dependent Radiosensitization of Histone Deacetylase Inhibitors Trichostatin A and SK-7041.

Purpose: This preclinical study is to determine whether the capacity of histone deacetylase (HDAC) inhibitors to enhance radiation response depends on temporal sequences of HDAC inhibition and irradiation.

Materials And Methods: The effects of HDAC inhibitors trichostatin A (TSA) and SK-7041 on radiosensitivity in human lung cancer cells were examined using a clonogenic assay, exposing cells to HDAC inhibitors in various sequences of HDAC inhibition and radiation. We performed Western blot of acetylated histone H3 and flow cytometry to analyze cell cycle phase distribution.

Transient anterior subcapsular vacuolar change of the crystalline lens in patients after posterior chamber phakic intraocular lens implantation.

Background: We present two cases of transient vacuolar changes in the anterior subcapsular space of the crystalline lens in patients after posterior chamber phakic intraocular lens implantation.

Case Presentation: Implantable collamer lenses (ICL) were implanted in healthy myopic patients. Vacuolar changes developed just after the irrigating procedure through the narrow space between the ICL and the crystalline lens.

MST1 functions as a key modulator of neurodegeneration in a mouse model of ALS.

Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disorder characterized by loss of motor neurons. Dominant mutations in the gene for superoxide dismutase 1 (SOD1) give rise to familial ALS by an unknown mechanism. Here we show that genetic deficiency of mammalian sterile 20-like kinase 1 (MST1) delays disease onset and extends survival in mice expressing the ALS-associated G93A mutant of human SOD1.

Optical coherence tomographic findings of crystal deposits in the lens and cornea in Bietti crystalline corneoretinopathy associated with mutation in the CYP4V2 gene.

Background: We report the optical coherence tomography (OCT) findings of crystalline deposits in the cornea and lens of a patient with Bietti crystalline dystrophy (BCD), thus providing evidence for a better understanding of the pathophysiology of BCD.

Patient: A 49-year-old man showing typical chorioretinal degeneration with a CYP4V2 mutation was diagnosed with BCD.

Observations: The anterior segment OCT images clearly showed flat hyperreflective plaques just beneath the corneal epithelium and in the lens epithelium.

Clinical utility of phentermine/topiramate (Qsymia™) combination for the treatment of obesity.

Qsymia™ (Vivus Inc, Mountain View, CA, USA), a combination of phentermine and delayed-release topiramate, has been available in the US since September 2012 for the treatment of obesity. Phentermine is an anorexigenic agent, which is approved for the short-term treatment of obesity, while topiramate is approved for nonweight loss indications - seizure disorders and migraine prophylaxis. The amount of weight loss achieved with combination therapy is of a greater magnitude than what could be achieved with either agent alone.

The application of comorbidity indices to predict early postoperative outcomes after laparoscopic Roux-en-Y gastric bypass: a nationwide comparative analysis of over 70,000 cases.

Background: Patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) often have substantial comorbidities, which must be taken into account to appropriately assess expected postoperative outcomes. The Charlson/Deyo and Elixhauser indices are widely used comorbidity measures, both of which also have revised algorithms based on enhanced ICD-9-CM coding. It is currently unclear which of the existing comorbidity measures best predicts early postoperative outcomes following LRYGB.

Divergence of flowering genes in soybean.

Soybean genome sequences were blasted with Arabidopsis thaliana regulatory genes involved in photoperioddependent flowering. This approach enabled the identification of 118 genes involved in the flowering pathway. Two genome sequences of cultivated (Williams 82) and wild (IT182932) soybeans were employed to survey functional DNA variations in the flowering-related homologs.

High risks for adverse outcomes after gastric bypass surgery following failed gastric banding: a population-based trend analysis of the United States.

Objectives: The objectives of this investigation were to (1) compare short-term outcomes for patients undergoing primary gastric bypass surgery with those who had gastric bypass procedures performed as a rescue procedure after failed gastric banding and (2) study trends in the frequency of reoperations between 2005 and 2008 for patients who had prior gastric banding.

Background: The use of gastric banding to treat obesity has increased drastically in the United States. However, the frequency of reoperations related to gastric banding and associated short-term outcomes are unknown.

Concurrent blockade of free radical and microsomal prostaglandin E synthase-1-mediated PGE2 production improves safety and efficacy in a mouse model of amyotrophic lateral sclerosis.

While free radicals and inflammation constitute major routes of neuronal injury occurring in amyotrophic lateral sclerosis (ALS), neither antioxidants nor non-steroidal anti-inflammatory drugs have shown significant efficacy in human clinical trials. We examined the possibility that concurrent blockade of free radicals and prostaglandin E(2) (PGE(2))-mediated inflammation might constitute a safe and effective therapeutic approach to ALS. We have developed 2-hydroxy-5-[2-(4-trifluoromethylphenyl)-ethylaminobenzoic acid] (AAD-2004) as a derivative of aspirin.

Predictors of and health services utilization related to depressive symptoms among elderly Koreans.

While the prevalence, comorbidity, risk profile and health care utilization for late-life depression have been described for many Western countries, much less is known about the recent epidemiology of late-life depression in East Asian countries such as Korea. We investigated predictors for depressive symptoms and the association between depressive symptoms and the utilization of both medical care and preventive services in elderly Koreans. Data were obtained from a nationally representative sample of Koreans aged 60 and above (2226 men, 2911 women) who participated in the 2008 wave of the Korean Longitudinal Study of Ageing.
