OBJECTIVE: Gestational hypertension is a pregnancy complication that serious damages the maternal and child health. Early onset severe preeclampsia accounts for about 0.9% of the gestational hypertension disease. Conservative treatment is proposed in recent years to early onset severe preeclampsia through delay delivery. Therefore, it is particularly important to explore the pathogenesis of severe preeclampsia. Soluble endoglin (sEng) has been identified as a central factor to induce endothelium dysfunction of preeclampsia, while its specific mechanism is unclear...

Entamoeba histolytica is the protozoan parasite that causes human amoebiasis. It is one of the leading parasitic disease burdens in tropical regions and developing countries, with spread to developed countries through migrants from and travellers to endemic regions. Understanding E. histolytica's invasion mechanisms requires an understanding of how it interacts with external cell components and how it engulfs and kills cells (phagocytosis). Recent research suggests that optimal phagocytosis requires signalling events from the cell surface to the nucleus via the cytoplasm, and the induction of several factors that are transported to the plasma membrane...

BACKGROUND: HSP90 is necessary for the conformational maturation of proteins, proteins disaggregation, folding new synthesized peptides and the refolding of denatured proteins. The inhibition of HSP90 leads to proteasomal degradations of client proteins that finally kill cancer cells. METHODS: In this research, molecular docking and comparative molecular field analysis (CoMFA) were used to investigate the interactions of tetrahydropyrido[4,3-d]pyrimidine derivatives with the N-terminal domain binding site of the HSP90 and predicting their inhibitory activities Results: A CoMFA model with five components and q2 of 0...

BACKGROUND: Cosmetic outcomes and scar lengths remain important considerations in breast cancer surgery. Suturing techniques should decrease scar tissue formation and provide good cosmetic results. The use of an accordion suturing technique may result in decreased surgical wound lengths and better cosmetic outcomes. We compared the outcomes of the accordion suturing technique with the standard suturing technique in breast cancer surgeries. MATERIALS AND METHODS: Female patients undergoing wide local excision of breast cancers were randomised to undergo closure of their surgical wound by either the accordion or the non-accordion (standard) suturing techniques between the months of May and October 2015...

Foot-and-mouth disease (FMD) is a major threat to the livestock industry worldwide. Despite constant surveillance and effective vaccination, the perpetual mutations of the foot-and-mouth disease virus (FMDV) pose a huge challenge to FMD diagnosis. The immunodominant region of the FMDV VP1 protein (residues 131-170) displayed on phage T7 has been used to detect anti-FMDV in bovine sera. In the present study, the functional epitope was further delineated using amino acid sequence alignment, homology modelling and phage display...

The mammalian heart is the first organ to form and is critical for embryonic survival and development. With an occurrence of 1%, congenital heart defects (CHDs) are also the most common birth defects in humans, and major cause of childhood morbidity and mortality (Hoffman and Kaplan in J Am Coll Cardiol 39(12):1890-1900, 2002; Samanek in Cardiol Young 10(3):179-185, 2000). Understanding how the heart forms will not only help to determine the etiology and to design diagnostic and therapeutic approaches for CHDs, but may also provide insight into regenerative medicine to repair injured adult hearts...

Clinical isolates of Pseudomonas aeruginosa from patients with cystic fibrosis (CF) are known to differ from those associated with non-CF hosts by colony morphology, drug susceptibility patterns, and genomic hypermutability. Pseudomonas aeruginosa isolates from CF patients have long been recognized for their overall reduced rate of antimicrobial susceptibility, but their intraclonal MIC heterogeneity has long been overlooked. Using two distinct cohorts of clinical strains ( n = 224 from 56 CF patients, n = 130 from 68 non-CF patients) isolated in 2013, we demonstrated profound Etest MIC heterogeneity in CF P...

Fungi can use a wide variety of nitrogen sources. In the absence of preferred sources such as ammonium, glutamate, and glutamine, secondary sources, including most other amino acids, are used. Expression of the nitrogen utilization pathways is very strongly controlled at the transcriptional level. Here, we investigated the regulation of nitrogen utilization in the pathogenic yeast Candida parapsilosis . We found that the functions of many regulators are conserved with respect to Saccharomyces cerevisiae and other fungi...

The hand and wrist are rare sites for tuberculosis (TB) and account for < 1% of all skeletal TB. Though rare, TB of the wrist is a cause of major morbidity. A common feature in the available reports on wrist TB is a delay in diagnosis causing residual stiffness and pain after treatment. Although TB of the wrist has a varied presentation, the majority of lesions respond to conservative treatment. We report a 12-year-old girl who presented with wrist swelling, having intercarpal, carpometacarpal, and radiocarpal joint involvement which turned out to be tuberculous and it healed with residual deformity...

Cancer cells reprogram energy metabolism by boosting aerobic glycolysis as a main pathway for the provision of metabolic energy and of precursors for anabolic purposes. Accordingly, the relative expression of the catalytic subunit of the mitochondrial H+ -ATP synthase-the core hub of oxidative phosphorylation-is downregulated in human carcinomas when compared with its expression in normal tissues. Moreover, some prevalent carcinomas also upregulate the ATPase inhibitory factor 1 (IF1), which is the physiological inhibitor of the H+ -ATP synthase...

Patellofemoral pain syndrome (PFPS) is one of the most common causes of knee pain and is present in females disproportionately more relative to males. PFPS causes tend to be multifactorial in nature and are described in this review. From a review of the current literature, it is clear that there needs to be further research on PFPS in order to better understand the complex etiology of this disorder in both males and females. It is known that females with patellofemoral pain syndrome demonstrate a decrease in abduction, external rotation and extension strength of the affected side compared with healthy patients...
