With nearly 140 α-glycosidases in 14 different families, plants are well equipped with enzymes that can break the α-glucosidic bonds in a large diversity of molecules. Here, we introduce activity-based protein profiling (ABPP) of α-glycosidases in plants using α-configured cyclophellitol aziridine probes carrying various fluorophores or biotin. In Arabidopsis (Arabidopsis thaliana), these probes label members of the GH31 family of Glycosyl Hydrolases, including ER-resident α-glucosidase-II RSW3/PSL5 (Radial Swelling-3/Priority for Sweet Life-5) and Golgi-resident α-mannosidase-II HGL1, both of which trim N-glycans on glycoproteins...

The Xinjiang Uyghur Autonomous Region of China (XUARC) harbors 47 ethnic groups including the Manchu (MCH: 0.11%), Mongols (MGL: 0.81%), Kyrgyz (KGZ: 0.86%) and Uzbek (UZK: 0.066%). To establish DNA databases for these populations, allele frequency distributions for 15 autosomal short tandem repeat (STR) loci were determined using the AmpFlSTR Identifiler PCR amplification kit. There was no evidence of departures from Hardy-Weinberg equilibrium (HWE) in any of the four populations and minimal departure from linkage equilibrium (LE) for a very small number of pairwise combinations of loci...

Fusarium oxysporum, a ubiquitous soil-borne pathogen causes devastating vascular wilt in more than 100 plant species and ranks fifth among top ten fungal plant pathogens. It has emerged as a human pathogen too, causing infections in immune-compromised patients. It is, therefore, important to gain insight into the molecular processes involved in the pathogenesis of this trans-kingdom pathogen. A complex network comprising of interconnected and over lapping signal pathways; mitogen-activated protein kinase (MAPK) signaling pathways, Ras proteins, G-protein signaling components and their downstream pathways, components of the velvet (LaeA/VeA/VelB) complex and cAMP pathways, is involved in perceiving the host...

Bluetongue virus (BTV) infection is an emerging hazard in small ruminants having socio-economic impacts on animals and associated people. The current study was aimed to estimate the sero-prevalence and associated risk factors in sheep and goat from Khyber Pakhtunkhwa (KP) province of Pakistan. Three distinct zones (northern, central and southern) with four districts (Mansehra, Abbottabad, Swabi, and Kohat) with a higher population of small ruminants were selected. A total of n = 408 sera originating from sheep (n = 212) and goats (n = 196) were randomly collected for detection of BTV group specific antibodies through competitive ELISA (c-ELISA)...

PURPOSE: Creatinine is normally used to evaluate kidney function among elderly patients in clinical practice, which has been reported to be affected by socio-demographic factors like BMI and age. Cystatin C a newly introduced biomarker may be more efficient in identifying kidney function in obese and aged CKD patients. The aim of the current study was to assess the effect of BMI on endogenous biomarkers (cystatin C and creatinine) among elderly CKD patients in Malaysia, a first such study in the country...

TGF β is a potent regulator of several biological functions in many cell types, but its role in the differentiation of human bone marrow-derived skeletal stem cells (hMSCs) is currently poorly understood. In the present study, we demonstrate that a single dose of TGF β 1 prior to induction of osteogenic or adipogenic differentiation results in increased mineralized matrix or increased numbers of lipid-filled mature adipocytes, respectively. To identify the mechanisms underlying this TGF β -mediated enhancement of lineage commitment, we compared the gene expression profiles of TGF β 1-treated hMSC cultures using DNA microarrays...

Alzheimer's disease (AD) is recognized as progressive multifaceted and multi-factorial neurodegenerative disorder which causes dementia among elderly people. Although, researchers in this field have put considerable efforts for the investigation of novel and appropriate therapeutic measures towards the cure of AD, unfortunately, no effective prevention therapy for this disease is available till date. In fact, various aspects involved in the onset and progression of AD are still disputed or uncovered. However, to achieve definite and direct cure of AD, researcher's attention has been drawn towards exploration of new therapeutics targets...

Nanotechnology exploits materials and devices with a functional organization that has been engineered at the nanometre scale. The application of nanotechnology in neuroscience involves specific interactions with neurons and glial cells. This property is used for delivering drugs and other small molecules (such as genes, oligonucleotides and contrasting agents) across the blood brain barrier (BBB), an important requirement for delivering the drug successfully to the brain. Nanotechnology based approaches (NBA) favoured transcytosis-mediated delivery of nanoparticles to the brain by crossing the BBB...

BACKGROUND: Many older adults living with dementia have not been formally diagnosed. Even when clinicians document the diagnosis, patients and families may be unaware of the diagnosis. Knowledge of how individual characteristics affect detection and awareness of dementia is limited. OBJECTIVE: To identify characteristics associated with dementia diagnosis and awareness of diagnosis. DESIGN: Cross-sectional observational study. PARTICIPANTS: Five hundred eighty-five adults aged ≥ 65 in the National Health and Aging Trends Study who met assessment-based study criteria for probable dementia in 2011 and had 3 years of continuous, fee-for-service Medicare claims prior to 2011...

BACKGROUND: Some 20-40% of the periampullary carcinoma is irresectable at the time of diagnosis. Biliary stenting and surgical bypass are commonly used palliative procedure. There is no consensus favouring one procedure over the other. This study compares the both procedures. METHODS: This Randomized Controlled Trial included 47 patients who presented with diagnosis of obstructive jaundice due to periampullary carcinoma to the Department of Surgery, Federal General Hospital, Islamabad from July 2012 to December 2014...

PURPOSE: Cancer immunotherapy has shown promising clinical outcomes in many patients. However, some patients still fail to respond, and new strategies are needed to overcome resistance. The purpose of this study was to identify novel genes and understand the mechanisms that confer resistance to cancer immunotherapy. EXPERIMENTAL DESIGN: To identify genes mediating resistance to T cell killing, we performed an open reading frame (ORF) screen of a kinome library to study whether overexpression of a gene in patient-derived melanoma cells could inhibit their susceptibility to killing by autologous Tumor-Infiltrating Lymphocytes (TILs)...

CHARGE syndrome is a condition that can disturb numerous areas of human body. As an abbreviation CHARGE stands for: coloboma, heart defects, atresia choanae, and retardation of growth, genital, and ear abnormalities. The configuration of malformations differs among individuals with this disorder, and the various health issues can be life-threatening during infancy and childhood. Affected individuals typically have several main features or a combination of major and minor appearances. Here we are presenting a case report of a neonate with CHARGE syndrome who underwent successful repair of choanal atresia under general anaesthesia with invasive monitoring...
