Endometrial expression of the estrogen-sensitive genes MMP-26 and TIMP-4 is altered by a substitution protocol without down-regulation in IVF patients.

BACKGROUND: The aim of this study was to analyse the effects of an estradiol (E2)–progesterone substitution protocol on the endometrial expression of estrogen-sensitive genes during the peri-implantation period. METHODS: Peripheral blood and endometrial biopsies were obtained from 13 infertile women both in a natural cycle (NC), on days 5 and 7 after ovulation (NC5, NC7), and in an artificial (sub

Heparan/chondroitin/dermatan sulfate primer 2-(6-hydroxynaphthyl)-O-beta-D-xylopyranoside preferentially inhibits growth of transformed cells

Xylose forms the direct carbohydrate-protein link in extra- or pericellular proteoglycans (PGs) that are substituted with either chondroitin sulfate (CS)/dermatan sulfate (DS) and/or heparan sulfate (HS). Cell surface PGs carrying HS are important regulators of cell growth. Xylose coupled to an aromatic compound can enter cells and initiate either CS/DS synthesis or both HS and CS/DS synthesis, de

Array based characterization of a terminal deletion involving chromosome subband 15q26.2: an emerging syndrome associated with growth retardation, cardiac defects and developmental delay.

BACKGROUND: Subtelomeric regions are gene rich and deletions in these chromosomal segments have been demonstrated to account for approximately 2.5% of patients displaying mental retardation with or without association of dysmorphic features. However, cases that report de novo terminal deletions on chromosome arm 15q are rare. METHODS: In this study we present the first example of a detailed molecu

Harvesting the decay energy of 26 Al to drive lightning discharge in protoplanetary discs

Chondrules in primitive meteorites likely formed by recrystallisation of dust aggregates that were flash-heated to nearly complete melting. Chondrules may represent the building blocks of rocky planetesimals and protoplanets in the inner regions of protoplanetary discs, but the source of ubiquitous thermal processing of their dust aggregate precursors remains elusive. Here we demonstrate that esca

A Fully Integrated 26dBm Linearized RF Power Amplifier in 65nm CMOS Technology

In this paper, design and measurements of a fully integrated power amplifier (PA) are presented. The PA consists of two amplifying chains each having a driver and a power stage. A low loss on chip power combiner combines the outputs from two amplifying chains, and also performs impedance transformation and differential to single-ended conversion. To linearize the PA, the driver stage is biased in

Energy Storage & Conversion

Sustainable energy storage and conversion explores innovative methods to efficiently store and transform energy from various renewable sources. It focuses on technologies like advanced batteries, hydrogen production, fuel cells, and thermochemical systems as well as safety aspects of battery storage systems. Research aims to enhance energy density, reduce costs, and improve scalability, enabling r

Influence of the mannan binding module of beta-mannanase CfMan26A in the hydrolysis of mannan

Hemicellulose is next to cellulose the most abundant polysaccharide on earth and as such an important renewable resource. Mannans are the major hemicellulose in so:ftwodd and are found as storage polysaccharide in various plants. -mannanases are the main mannan degrading enzymes. In this work the -1,4-mannanase from the soilliving bacteria Cellulosamas Jimi was studied and special focus was put on

Safe Spaces in Unsafe Environments-Experiences from COP26 About Hosting Inclusive Spaces for Deep Encounters and Reflection

Transdisciplinary research (TDR) seeks to involve non-academic perspectives from the start, ensuring that research draws on diverse knowledge to better address “wicked” problems. Since TDR researchers have to engage with non-academic perspectives throughout the research process, this chapter focuses on the kind of communication practices that are appropriate and effective for engaging with people
