Specificity protein (Sp) transcription factors (TFs) such as Sp1 are critical for early development but their expression decreases with age and there is evidence that transformation of normal cells to cancer cells is associated with upregulation of Sp1, Sp3 and Sp4 which are highly expressed in cancer cells and tumors. Sp1 is a negative prognostic factor for pancreatic, colon, glioma, gastric, breast, prostate, and lung cancer patients. Functional studies also demonstrate that Sp TFs regulate genes responsible for cancer cell growth, survival, migration/invasion, inflammation and drug resistance, and Sp1, Sp3 and Sp4 are also non-oncogene addiction (NOA) genes and important drug targets...

BACKGROUND: Deficits of inhibitory control in early childhood are linked to externalizing behaviors and attention problems. While environmental factors and physiological processes are associated with its etiology, few studies have examined how these factors jointly predict inhibitory control. This study examined whether respiratory sinus arrhythmia (RSA) functioned as a mediator or moderator of both cumulative sociodemographic risk and parenting behaviors on inhibitory control during early childhood...

The objective of this study was to identify genes regulated by methylation that were involved in spermatogenesis failure in non-obstructive azoospermia (NOA). Testis biopsies of patients with NOA and OA (with normal spermatogenesis) were evaluated by microarray analysis to examine DNA methylation and mRNA expression using our established integrative approach. Of the coordinately hypermethylated and down-regulated gene list, zinc-finger CCHC-type containing 13 ( ZCCHC13 ) was present within the nuclei of germ cells of testicular tissues according immunohistochemistry, and there was decreased protein expression in men with NOA compared with OA controls...

Nonobstructive azoospermia (NOA) patients present with high levels of serum FSH. At the protein level, the aetiology and pathways underlying different subtypes of NOA are unclear. The aim was to evaluate quantitatively differences in proteomic profiles of NOA patients presenting with normal serum FSH and normal testicular volume and high serum FSH and small testicular volume. The study comprised of 14 nonobstructive azoospermic men (N = 4; normal FSH and normal testicular volume and N = 10; high FSH and small testicular volume) and seven normozoospermic men...

BACKGROUND: Although many reports show that various kinds of stem cells have the ability to recover function in premature ovarian aging, few studies have looked at stem cell treatment of natural ovarian aging (NOA). We designed this experimental study to investigate whether human amniotic mesenchymal stem cells (hAMSCs) retain the ability to restore ovarian function, and how hAMSCs work in this process. METHODS: To build the NOA mouse model, the mice were fed for 12-14 months normally with young fertile female mice as the normal control group (3-5 months old)...

Existing approaches to describe social interactions consider emotional states or use ad-hoc descriptors for microanalysis of interactions. Such descriptors are different in each context thereby limiting comparisons, and can also mix facets of meaning such as emotional states, short term tactics and long-term goals. To develop a systematic set of concepts for second-by-second social interactions, we suggest a complementary approach based on practices employed in theater. Theater uses the concept of dramatic action, the effort that one makes to change the psychological state of another...

We have developed a new effective in-operando methodology for investigating oxygen reduction reactions (ORR) and their mechanisms in non-aqueous solutions, based on UV-Vis spectroscopy in conjunction with various electrochemi-cal techniques. We can follow in-situ the formation and presence of superoxide moieties during ORR as a function of the solvent, cations, anions and additives in solution. Thus, using in-operando UV-Vis spectroscopy, we found evidence for the formation of superoxide radical anions during oxygen reduction in LiTFSI/diglyme electrolyte solutions...

BACKGROUND As a safety and efficacy protocol, oocyte vitrification has been widely used in IVF treatment. The aim of this study was to evaluate the outcome of ICSI-ET utilizing vitrified oocytes with sperm obtained from non-obstructive azoospermia (NOA) patients via micro-TESE. MATERIAL AND METHODS A total of 150 NOA patients underwent micro-TESE. Ten patients were unable to ejaculate and refused to accept TESA at the time of oocyte retrieval; later, these patients underwent TESA. A total of 174 obstructive azoospermia (OA) patients underwent TESA...

BACKGROUND: Disordered eating behaviors (DEBs) may lead to full blown eating disorders. Both type 1 diabetes mellitus (T1DM) and celiac disease (CD) have been linked to DEBs. OBJECTIVE: To compare the presence of DEBs between adolescents and young adults with a dual diagnosis of T1DM and CD, and individuals with only one of the diagnoses. METHODS: Individuals with a dual diagnosis of T1DM and CD ("T1DM + CD group" n = 39), with a diagnosis of T1DM only ("T1DM group" n = 97) and with a diagnosis of CD only ("CD group" n = 267) filled the Eating Attitude Test-26 (EAT-26) questionnaire...

Most habitats in nature are heterogeneous, incorporating favorable and unfavorable microhabitats for different animals, based on their ecological niche. Unsuitable microhabitats have negative consequences for individual growth and survival. Animals, therefore, should fine-tune their location within the habitat by dispersing away from such microhabitats. We studied the suitability of different constant microhabitat conditions for wormlion larvae, a trap-building predator, tested in groups under laboratory conditions...

Pit-building antlions and wormlions are 2 distantly-related insect species, whose larvae construct pits in loose soil to trap small arthropod prey. This convergent evolution of natural histories has led to additional similarities in their natural history and ecology, and thus, these 2 species encounter similar abiotic stress (such as periodic starvation) in their natural habitat. Here, we measured the cold tolerance of the 2 species and examined whether recent feeding or food deprivation, as well as body composition (body mass and lipid content) and condition (quantified as mass-to-size residuals) affect their cold tolerance...

Human gut microbiome composition is shaped by multiple factors but the relative contribution of host genetics remains elusive. Here we examine genotype and microbiome data from 1,046 healthy individuals with several distinct ancestral origins who share a relatively common environment, and demonstrate that the gut microbiome is not significantly associated with genetic ancestry, and that host genetics have a minor role in determining microbiome composition. We show that, by contrast, there are significant similarities in the compositions of the microbiomes of genetically unrelated individuals who share a household, and that over 20% of the inter-person microbiome variability is associated with factors related to diet, drugs and anthropometric measurements...

PURPOSE: Despite its proven efficacy, low participation rates in cardiac prevention and rehabilitation programs (CPRPs) prevail worldwide, especially among ethnic minorities. This is strongly evident in Israel's Arab minority. Since psychological distress has been found to be associated with CPRP participation and minorities are subjected to higher levels of distress, it is plausible that distress may be an important barrier for CPRP participation among minority patients. The current prospective study assessed the contribution of depression and anxiety symptoms to participation in a CPRP after acute coronary syndrome, both in the enrollment phase and when considering adherence over time, among Jewish (majority) and Arab (minority) patients in Israel...

Schizophrenia is a debilitating psychiatric condition often associated with poor quality of life and decreased life expectancy. Lack of progress in improving treatment outcomes has been attributed to limited knowledge of the underlying biology, although large-scale genomic studies have begun to provide insights. We report a new genome-wide association study of schizophrenia (11,260 cases and 24,542 controls), and through meta-analysis with existing data we identify 50 novel associated loci and 145 loci in total...

Although there is emerging evidence that mast cells are involved in infertility, their exact role has not been elucidated clearly. Here we carried out a retrospective case-control study to find out whether there is a correlation between mast cell (MC) count and proliferation (Ki67 index) of the spermatogenic epithelium as well as of the Sertoli cells (vimentin-positive) in non-obstructive azoospermia (NOA). We assessed MCs, Ki67 and vimentin expression in Sertoli cells in testicular biopsies of germ cell aplasia (GCA, n = 14) and maturation arrest (MA, n = 14) vs...

Over-reliance on pesticides for pest control is inflicting serious damage to the environmental services that underpin agricultural productivity. The widespread use of systemic insecticides, neonicotinoids, and the phenylpyrazole fipronil in particular is assessed here in terms of their actual use in pest management, effects on crop yields, and the development of pest resistance to these compounds in many crops after two decades of usage. Resistance can only be overcome in the longterm by implementing methods that are not exclusively based on synthetic pesticides...

INTRODUCTION: Twin vaginal delivery presents a unique clinical challenge for obstetricians. The twin birth study demonstrated the safety of planned vaginal delivery regarding neonatal outcomes. However, that study lacked description of the risk factors associated with and the outcome of unplanned cesarean section. The aim of this study is to identify potential risk factors for cesarean section and delivery related neonatal morbidity and mortality in women with twin pregnancy attempting vaginal delivery...

Disrupted somatosensory processing characterized by over- or under- responsiveness to environmental stimuli plays an important, yet often overlooked, role in typical development and is aberrant in various neurodevelopmental disorders. These dysfunctional somatosensory processes have been conceptualized as an entity termed somatosensory dysregulation (SMD). Since Tourette syndrome (TS) is a prototypical example of developmental psychopathological disorder, we hypothesised that SMD would be a feature found in children suffering from the disorder...
