RNA-Seq of the Catharanthus roseus SRA database was done in order to detect putative universal stress proteins (USPs) and their possible controlling factors. Previous analysis indicated the existence and characterization of uspA-like genes. In silico analysis of RNA-Seq database in several plant tissues revealed the possible functions and regulations of some uspA-like transcripts whose transcription factors (TFs) that might drive their expression were detected. BLAST indicated the existence of TF superfamilies erf (ethylene-responsive TF), bHLH (basic helix-loop-helix) and WRKY that might regulate several uspA-like genes...

BACKGROUND: Climate change is predicted to be a serious threat to agriculture due to the need for crops to be able to tolerate increased heat stress. Desert plants have already adapted to high levels of heat stress so they make excellent systems for identifying genes involved in thermotolerance. Rhazya stricta is an evergreen shrub that is native to extremely hot regions across Western and South Asia, making it an excellent system for examining plant responses to heat stress. Transcriptomes of apical and mature leaves of R...

BACKGROUND: The ultimate goal of this work was to detect the role of transcription factors (TFs) concordantly expressed with genes related to programmed cell death (PCD) during PCD and salt stress. This work was based on the hypothesis that TFs and their driven genes likely co-express under different stimuli. The conserved superfamily ethylene responsive factor (AP2/ERF) draw attention of the present study as it participates in the response to biotic and abiotic stimuli as well as to program cell death (PCD)...

Cancer is a major health problem to human beings around the world. Many quinazoline derivatives were reported to have potent cytotoxic activity. Our aim in this work is the discovery of potent epidermal growth factor receptor (EGFR) inhibitors with anti-breast cancer activity containing 4-substituted quinazoline pharmacophore. Novel series of 4-substituted 6,8-dibromo-2-(4-chlorophenyl)-quinazoline derivatives have been designed and synthesized. New derivatives were tested against MCF-7 (human breast carcinoma cell line) and screened for their inhibition activity against epidermal growth factor receptor tyrosine kinase (EGFR-TK)...

Alternative splicing (AS) of precursor RNAs enhances transcriptome plasticity and proteome diversity in response to diverse growth and stress cues. Recent work showed that AS is pervasive across plant species, with more than 60% of intron-containing genes producing different isoforms. Mammalian cell-based assays have discovered various AS inhibitors. Here, we show that the macrolide Pladienolide B (PB) inhibits constitutive splicing and AS in plants. Also, our RNA-seq data revealed that PB mimics abiotic stress signals including salt, drought, and abscisic acid (ABA)...

BACKGROUND: Minimal hepatic encephalopathy (MHE) has a far-reaching impact on quality and function ability in daily life and may progress to overt hepatic encephalopathy. There is a synergistic effect between systemic oxidative stress and ammonia that is implicated in the pathogenesis of hepatic encephalopathy. The aim of this study is to investigate the effectiveness of oral supplementation of antioxidants and zinc gluconate on MHE versus lactulose. METHODS: Our study included 58 patients with cirrhosis diagnosed as having MHE by neuropsychometric tests, including number connection test part A (NCT-A), digit symbol test (DST) and block design tests (BDTs)...

Sexually transmitted infections (STIs) are major health threats affecting people globally; however, the burden of STIs is greatest in low-income countries. Since they are physiologically more vulnerable, women are mostly affected. The risk is increased dramatically during pregnancy leading to serious health complications that may affect the newborn. Underprivileged pregnant women attending antenatal clinics for routine checkups in displaced camps, a women's prison and several peripheral health centres were clinically and laboratory screened for trichomoniasis, chlamydial infections, gonorrhea and syphilis...

Atrial septal defects (ASDs) account for approximately 6%-10% of congenital heart defects. The well-known types of atrial septal communications are the ostium secundum, ostium primum, sinus venosus types, and coronary sinus defects. A 50-year-old female was referred for TEE for better assessment of MR severity and mechanism. 2D/3D-TEE showed a rare combination of different abnormalities; bi-leaflet mitral valve prolapse, cleft P2, cor triatriatum sinister, and a tunnel-shaped IAS communication. To the best of our knowledge, this is a very rare case with a rare form of atrial septal defect that was not described before...

Tomato is an important vegetable crop and its production is adversely affected by leaf curl disease caused by begomovirus. Leaf curl disease is a serious concern for tomato crops caused by begomovirus in Jeddah, Kingdom of Saudi Arabia. Tomato leaf curl disease has been shown to be mainly caused either by tomato leaf curl Sudan virus or tomato yellow leaf curl virus as well as tomato leaf curl Oman virus. Many tomato plants infected with monopartite begomoviruses were also found to harbor a symptom enhancing betasatellites...

Asthma is a heterogeneous disease, in which asthmatic patients present with different clinical phenotypes, variable endotypes, and different response to asthma medicines. Thus, we are faced with an asthma paradox; asthma is diagnosed subjectively by clinical history and treated with biologically active drugs. To solve this paradox, we need objective airway biomarkers to tailor the proper medications to the proper patient. Biomarkers should have one or more of the following characteristics:1) A biomarker that could differentiate poor symptoms perceivers from over perceivers, 2) A biomarker that could predict disease activity and hence disease outcome, 3) A biomarker that could clarify responders from non-responders asthma phenotypes, and finally 4) A biomarker that could characterize different clinical asthma phenotypes...
