Adult onset Still's disease (AOSD) is a chronic inflammatory disorder involving multiple systems. The symptoms mimic those of lymphomas, therefore, the diagnosis of lymphoma needs to be excluded prior to establishing the diagnosis of AOSD. Another similar condition is dermatopathic lymphadenopathy (DL). In DL, the histopathological appearance of lymph node biopsy may also mimic AOSD. The DL is associated with several systemic pathologies, such as malignant lymphomas, and rarely AOSD. We present a case of a 43-year-old male presented with 3 months history of fatigue, fever, and lymphadenopathy...

For most of the time, biomedical researchers have been dealing with ordinal outcome variable in multilevel models where patients are nested in doctors. We can justifiably apply multilevel cumulative logit model, where the outcome variable represents the mild, severe, and extremely severe intensity of diseases like malaria and typhoid in the form of ordered categories. Based on our simulation conditions, Maximum Likelihood (ML) method is better than Penalized Quasilikelihood (PQL) method in three-category ordinal outcome variable...

This review provides an insight into the beta-cyanoalanine synthase pathway in higher plants for cyanide (CN) detoxification and describes how it contributes to various physiological activities, such as plant growth and development. In higher plants, CN is produced as a natural toxin through the biosynthesis of ethylene and camalexin, the degradation of glucosinolates and cyanogenic glycosides, the oxidation of amino acids, and the metabolism of glyoxylate and hydroxylamine. To maintain cellular homeostasis by maintaining CN at non-toxic levels, plants have evolved four different biochemical pathways: the β-cyanoalanine synthase pathway (beta-CASP), the thiocyanate pathway, the formamide hydrolase pathway, and the natural release of CN through volatilization...

First developed by the World Health Organization, and now used in several countries, water safety plans (WSPs) are a multi-step, preventive process for managing drinking water hazards. While the beneficial impacts of WSPs have been documented in diverse countries, how to successfully implement WSPs in the United States remains a challenge. We examine the willingness and ability of water utility leaders to implement WSPs in the US state of North Carolina. Our findings show that water utilities have more of a reactive than preventive organizational culture, that implementation requires prioritization of time and resources, perceived comparative advantage to other hazard management plans, leadership in implementation, and identification of how WSPs can be embedded in existing work practices...

Cumulatively, degenerative disease is one of the most fatal groups of diseases, and it contributes to the mortality and poor quality of life in the world while increasing the economic burden of the sufferers. Oxidative stress and inflammation are the major pathogenic causes of degenerative diseases such as rheumatoid arthritis (RA), diabetes mellitus (DM), and cardiovascular disease (CVD). Although a number of synthetic medications are used to treat these diseases, none of the current regimens are completely safe...

Family-1 UDP-glycosyltransferases (EC 2.4.1.x; UGTs) are enzymes that glycosylate aglycones into glycoside-associated compounds with improved transport and water solubility. This glycosylation mechanism is vital to plant functions, such as regulation of hormonal homeostasis, growth and development, xenobiotic detoxification, stress response, and biosynthesis of secondary metabolites. Here, we report a genome-wide analysis of soybean that identified 149 putative UGTs based on 44 conserved plant secondary product glycosyl-transferase (PSPG) motif amino acid sequences...

In vivo and in vitro tests are the two major ways of identifying the triggering allergens in sensitized individuals with allergic symptoms. Both methods are equally significant in terms of sensitivity and specificity. However, in certain circumstances, in vitro methods are highly preferred because they circumvent the use of sensitizing drugs in patients. In current study, we described a highly sensitive immuno-PCR (iPCR) assay for serum IgE specific to Bermuda allergens. Using oligonucleotide-labelled antibody, we used iPCR for the sensitive detection of serum IgE...

Injuries to the spinal cord often have devastating physiological impacts due to the organ's vital role in neuro-impulse communications between muscles and the brain. Spinal Cord Injuries (SCIs) have recently been estimated to affect up to 80,000 individuals per year worldwide, with most occurring following a traumatic event. Unfortunately, effective treatments standardised globally for patients with SCIs have not yet been established. For many years, inadequate understanding of the complexities of the Central and Peripheral Nervous Systems and Neurogenesis has limited progression towards effective cures...

OBJECTIVE: The ATP-binding cassette transporter superfamily is one of the largest membrane protein families which is responsible for transportation of substances across the membranes by utilizing energy. Several researches have bridged the variations in ABCA13 with occurrence of psychiatric disorders. To investigate the overlapping risk conferred by ABCA13 for both major depressive disorder and schizophrenia, we analyzed tag single nucleotide polymorphisms (tag SNPs). METHOD: We used TaqMan® technology to genotype 1045 major depressive disorder patients, 1235 schizophrenia patients and 1235 healthy controls of Han Chinese origin...

The alteration of glucose metabolism, through increased uptake of glucose and glutamine addiction, is essential to cancer cell growth and invasion. Increased flux of glucose through the Hexosamine Biosynthetic Pathway (HBP) drives increased cellular O-GlcNAcylation (hyper-O-GlcNAcylation) and contributes to cancer progression by regulating key oncogenes. However, the association between hyper-O-GlcNAcylation and activation of these oncogenes remains poorly characterized. Here, we implement a qualitative modeling framework to analyze the role of the Biological Regulatory Network in HBP activation and its potential effects on key oncogenes...

Transcatheter aortic valve replacement as an alternative to open surgical repair is rapidly becoming more used in high-risk patients with aortic stenosis. Transcatheter aortic valve replacement offers the benefit of being much less invasive than traditional surgical repair and has evolved as a therapeutic option for patients with prohibitive surgical risk or those deemed surgically inoperable. Nevertheless, despite its potential to mitigate risk in this frail population, it comes with its own unique set of complications...

Parkinson's disease (PD) is a devastating and progressive movement disorder characterized by symptoms of muscles rigidity, tremor, postural instability and slow physical movements. Biochemically, PD is characterized by lack of dopamine production and its action due to loss of dopaminergic neurons and neuropathologically by the presence of intracytoplasmic inclusions known as Lewy bodies, which mainly consist of presynaptic neuronal protein, α-synuclein (α-syn). It is believed that alteration in α-syn homeostasis leads to increased accumulation and aggregation of α-syn in Lewy body...
