The hybrid power system (HPS) is an emerging power generation scheme due to the plentiful availability of renewable energy sources. Renewable energy sources are characterized as highly intermittent in nature due to meteorological conditions, while the domestic load also behaves in a quite uncertain manner. In this scenario, to maintain the balance between generation and load, the development of an intelligent and adaptive control algorithm has preoccupied power engineers and researchers. This paper proposes a Hermite wavelet embedded NeuroFuzzy indirect adaptive MPPT (maximum power point tracking) control of photovoltaic (PV) systems to extract maximum power and a Hermite wavelet incorporated NeuroFuzzy indirect adaptive control of Solid Oxide Fuel Cells (SOFC) to obtain a swift response in a grid-connected hybrid power system...

Two key enzymes of the ribulose monophosphate (RuMP) cycle for formaldehyde fixation, 3-hexulose-6-phosphate synthase (HPS) and 6-phospho-3-hexulose isomerase (PHI), in the aerobic halotolerant methanotroph Methylomicrobium alcaliphilum 20Z are encoded by the genes hps and phi and the fused gene hps-phi. The recombinant enzymes HPS-His6, PHI-His6, and the two-domain protein HPS-PHI were obtained by heterologous expression in Escherichia coli and purified by affinity chromatography. PHI-His6, HPS-His6 (2 × 20 kDa), and the fused protein HPS-PHI (2 × 40 kDa) catalyzed formation of fructose 6-phosphate from formaldehyde and ribulose-5-phosphate with activities of 172 and 22 U/mg, respectively...

In normal colonic epithelium, the proliferative zone is limited to the lower half of the colonic crypt. Evaluating the changes in the colonic epithelial proliferation can be useful in understanding pathophysiology of various diseases. Our aim was to investigate the proliferative compartment of serrated polyps (SPs) using MCM2, a protein involved in DNA replication, and assess for changes along the SP spectrum. Immunohistochemistry was performed on serrated polyps (16 microvesicular-type hyperplastic polyps (HP), 58 sessile serrated adenomas (SSA), seven SSAs with dysplasia) and six sections of normal colon using anti-MCM2 antibody...

Hermansky-Pudlak syndrome (HPS) is a heterogeneous group of genetic disorders typically manifesting with tyrosinase-positive oculocutaneous albinism, bleeding diathesis, and pulmonary fibrosis, in some subtypes. Most HPS subtypes are associated with defects in Biogenesis of Lysosome-related Organelle Complexes (BLOCs), which are groups of proteins that function together in the formation and/or trafficking of lysosomal-related endosomal compartments. BLOC-2, for example, consists of the proteins HPS3, HPS5, and HPS6...

We describe a new finding, the "excessive bright echoes" sign, for the diagnosis of hypertrophic pyloric stenosis (HPS). Portal venous gas and gastric wall pneumatosis were noted in 4 vomiting infants proven to have HPS. Portal venous gas can be concerning for ischemic bowel. Gastric wall pneumatosis can be seen in association with necrotizing enterocolitis and has been associated with increased gastric pressure from severe, usually proximal, bowel obstruction. Our HPS cases had prominent bright punctate echoes on sonography of the liver, portal vein lumen, and gastric wall...

The European Society for Clinical Nutrition has published recommendations on the "definition and classification of intestinal failure (IF)". Two criteria must be present: a "decreased absorption of macronutrients and/or water and electrolytes due to a loss of gut function" and the "need for parenteral support". Home parenteral support (HPS) is the primary treatment for chronic IF but is associated with complications. Areas covered: The principal cause of chronic IF is short bowel syndrome (SBS). The aim of treatment is to maximize intestinal absorption and reduce or eliminate the need for HPS to achieve the best possible quality of life...

BACKGROUND: The relationship between bipolar disorder (BD) and creativity is well-known; however, relatively little is known about its potential mechanism. We investigated whether heightened behavioral activation system (BAS) sensitivity may mediate such relationship. METHODS: Korean young adults (N=543) completed self-report questionnaires that included the Hypomanic Personality Scale (HPS), the Behavioral Activation System(BAS) Scale, the Everyday Creativity Scale (ECS), the Positive Affect and Negative Affect Schedule (PANAS), and the Altman Self-Rating Mania Scale (ASRM)...

Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder causing oculocutaneous albinism, bleeding disorder and ceroid lipofuscinosis. Platelets from HPS patients are characterized by impaired secretion of dense (δ)-bodies (CD63). Meanwhile, there are ten known human HPS genes, each leading to a particular clinical HPS subtype (HPS1-HPS10). We report on two Turkish brothers showing typical HPS phenotype comprising oculocutaneous albinism and bleeding symptoms. Pathological bleeding time as well as platelet aggregometry analyses revealed impaired platelet function...

Serrated polyps have long been considered to lack malignant potential but accumulating data suggest that these lesions may cause up to one-third of all sporadic colorectal cancer. Serrated polyps are classified into three subtypes, including sessile serrated adenomas/polyps (SSA/Ps), traditional serrated adenomas (TSAs), and hyperplastic polyps (HPs). SSA/P and TSA harbour malignant potential but TSA represents only 1-2%, wheras SSA/P constitute up to 20% of all serrated lesions. HPs are most common (80%) of all serrated polyps but are considered to have a low potential of developing colorectal cancer...

BACKGROUND: Anti-malarial herbal preparations (HPs) continue to enjoy high patronage in Ghana despite reports that the artemisinin-based combination therapy (ACT), the recommended first choice for treatment of uncomplicated malaria in the country, remains efficacious. A major issue with the use of these preparations is inadequate or unreliable data on their efficacy and quality. An assessment of the potency and quality of the most popular commercial anti-malarial HPs in Ghana was, therefore, carried out...

BACKGROUND: Repeated measurements of hepatitis C virus (HCV) RNA levels during antiviral therapy are recommended to monitor treatment efficacy and adherence. Throughout most direct antiviral agent (DAA) approval studies, HCV RNA cutoffs and endpoints were established with the COBAS TaqMan assay for use with the High Pure System (HPS/CTM). Different assays used in clinical practice may yield different quantitative results and possibly impact treatment decisions. OBJECTIVES: The concordance of the fully-automated COBAS AmpliPrep/COBAS TaqMan assay (CAP/CTM) with HPS/CTM and its ability to predict response to DAA-treatment with ledipasvir/sofosbuvir was assessed in cirrhotic patients with HCV genotype-1-infection who had failed prior treatment with protease inhibitor-based regimens...

BACKGROUNDS AND AIMS: The Japan NBI Expert Team (JNET) classification is the first universal narrow-band imaging (NBI) magnifying endoscopic classification of colorectal tumors. Considering each type in this classification, the diagnostic ability of Type 2B is the weakest. Generally, clinical behavior is thought to be different in each gross type of colorectal tumor. We evaluated the differences in the diagnostic performance of JNET classification for each gross type (polypoid and superficial) and examined whether the diagnostic performance of Type 2B could improve by subtyping...

Evidence suggests that bipolar psychopathology is better characterized as a spectrum than by categorical diagnoses. The examination of symptoms and impairment associated with bipolar spectrum psychopathology is important and can be enhanced by methods that examine affect, thoughts, and behavior in daily life. The present study extended findings that provide validation of a continuum of bipolar psychopathology in daily life. Young adults (n=294) completed the Hypomanic Personality Scale (HPS) and experience sampling using smartphones...
