The alkaline earth nitridogermanate nitrides AE(7)[GeN(4)]N(2) (AE = Ca, Sr) have been synthesized using a Na flux technique in sealed Ta tubes. According to single-crystal X-ray diffraction the isotypic compounds crystallize in space group Pbcn (No. 60) with Z = 4, (Sr(7)[GeN(4)]N(2): a = 1152.6(2), b = 658.66(13), c = 1383.6(3) pm, V = 1050.5(4) x 10(6) pm(3), R1 = 0.049; Ca(7)[GeN(4)]N(2): a...

Di‑(2‑ethylhexyl) phthalate (DEHP) and genistein (GEN) are of the most common endocrine disrupting chemicals (EDCs) present in the environment or the diet. However, investigation of the effects of acute exposure to these two EDCs during prepuberty has been lacking. In this study, DEHP and GEN were administrated to prepubertal male Sprague‑Dawley rats by gavage from PND22 to PND35 with vehicle c...

Two new endemic genera and species of extinct group of Hyolitha, Skryjelites auritus gen. et sp. nov. and Quasimolites quasimodo gen. et sp. nov. are described and illustrated from the Buchava Formation of the Barrandian area (Czech Republic).

STUDY QUESTION What is the variability of anti-Müllerian hormone (AMH) concentration in repeat samples from the same individual when using the Gen II assay and how do values compare to Gen I [Diagnostic Systems Ltd (DSL)] assay results? SUMMARY ANSWER The Gen II AMH assay displayed appreciable variability, which can be explained by sample instability. WHAT IS KNOWN ALREADY AMH is the primar...

A split preorder is a preordering relation on the disjoint union of two sets, which function as source and target when one composes split preorders. The paper presents by generators and equations the category SplPre, whose arrows are the split preorders on the disjoint union of two finite ordinals. The same is done for the subcategory Gen of SplPre, whose arrows are equivalence relations, and f...

OBJECTIVES Genistein is known to influence reproductive system development through its binding affinity for estrogen receptors. The present study aimed to further explore the effect of Genistein on the development of the reproductive system of experimental rats. METHODS Eighteen post-weaning female Sprague Dawley rats were divided into the following groups: (i) a control group that received v...

Tissue biopsy is often not very accurate for the diagnosis of gastric epithelial neoplasia (GEN), and the results differ notably from endoscopic resection (ER) in terms of the pathological diagnosis. The aims of this study were to evaluate the diagnostic performances of biopsy, magnifying endoscopy with narrow-band imaging (ME-NBI), and biopsy plus ME-NBI for GEN.This study retrospectively anal...

Thirteen species of basal Brachycera (11 described as new) are reported, belonging to nine families and three infraorders. They are preserved in amber from the Early Cretaceous (Neocomian) of Lebanon, Albian of northern Spain, upper Albian to lower Cenomanian of northern Myanmar, and Late Cretaceous of New Jersey USA (Turonian) and Alberta, Canada (Campanian). Taxa are as follows, with signific...

DEFINITIONS Gaze-evoked Gaze-evoked nystagmus (GEN) is a jerk nystagmus, not present in primary position, elicited by attempted maintenance of eccentric eye position, GEN may have a linear or a decreasing-velocity exponential slow phase; the latter has sometimes been referred to as gaze-paretic nystagmus but, unless it is due to a muscle or nerve paresis, the GEN terminology is preferred. Disti...
