Trp8Arg polymorphism of the LH beta gene has decreased bioactivity in vivo and previous studies showed conflicting data on the effect of LH beta gene polymorphism on the IVF outcome. In this study, 591 IVF patients were recruited. Patients with the variant allele(s) were the carrier group. In GnRH antagonist cycles, the clinical pregnancy rate was significantly lower in the carrier group (18.9%) than in the noncarrier group (37.1%). In long GnRH agonist cycles, the clinical pregnancy rate was comparable between both groups. To clarify the effect of COH protocols, IVF outcomes in the GnRH antagonist and long GnRH agonist protocol groups in carriers were analysed. Among carriers, the clinical pregnancy rate was significantly lower in the GnRH antagonist protocol group (18.9%) than in the long GnRH agonist protocol group (45.2%). Single nucleotide polymorphism analysis may contribute to the individualisation of COH protocols for each patient in the future. Impact Statement What is already known on this subject? Trp8Arg polymorphism of the LH beta gene is known to have decreased bioactivity in vivo. Previous studies have demonstrated hypo-sensitivity in the patients with the variant LH beta protein, while other study showed similar carrier frequency between the poor and the normal response group. Whatthe results of this study add? The variant LH beta gene was associated with a lower clinical pregnancy rate in GnRH antagonist cycles but not in long GnRH agonist cycles. Whatthe implicationsareof these findings for clinical practice and/or further research? Single nucleotide polymorphism analysis may contribute to the individualisation of COH protocols for each patient in the future.
  The most common large-deletion RHD allele (RHD*01N.01) includes the entire coding sequence, intervening regions and untranslated regions. The rest of large-deletion RHD alleles reported to-date consist of single-exon deletions, such as RHD*01N.67 which includes exon 1.
 
  Samples from two donors with RhD-negative serology yielded unclear or inconclusive results when subject to confirmatory testing on RHD genotyping arrays. To determine their RHD genotypes, genomic DNA was analyzed with a combination of allele-specific PCR, long-range PCR, Sanger sequencing, and next-generation sequencing assays.
 
  Allele-specific PCR failed to detect products for RHD exons 1 to 3 in one sample and RHD exons 1 to 5 in the other.  https://www.selleckchem.com/products/cilofexor-gs-9674.html  A quantitative next-generation sequencing assay confirmed deletion of exons 1 to 3 and 1 to 5 respectively, and detected the absence of an RHD gene in trans in both samples. Long-range PCR and Sanger sequencing enabled identification of the breakpoints for both alleles. Both deletions start within the 5' Rhesus box (upstream of the identity region for the 1-to-3 deletion, downstream of it for the 1-to-5 deletion), and end within introns.
 
  Resolution of unclear or inconclusive results from targeted genotyping arrays often leads to the discovery of new alleles. The 5' Rhesus box may be a hot spot for genetic recombination events, such as the large deletions described in this report.

The emerging industry of edible arthropods is trying to change that. The best shopping spot to buy well-known edible arthropods is online today. Consumers can find numerous outlet options to buy edible arthropods from the Internet. With worldwide growing threats to food security, today, gastronomy, especially in western countries, is trying to develop a more positive view to arthropods' nutritional value. In this paper, non-crustacean arthropods (armor tail scorpion, black scorpion, black ant, flying termites, giant waterbug, June beetle, diving beetles, rhino beetles, silkworm pupae, sago worm, bamboo worm), bought from online edible insect market, were evaluated in terms of availability of some hazardous chemical. Energy Dispersive X-Ray Fluorescence (EDXRF) spectroscopy was used for determining the concentrations of heavy metals/metalloids in the total body of the arthropods. Concentration of the elements (Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Pb) were measured quantitatively in all samples. The results showed that the chemicals like Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, and Pb have highly been measured in the black scorpion, black ant, flying termites, giant waterbug, June beetle, sago worm, and bamboo worm.
  Honokiol and magnolol were considered as markers for the analysis of Cortex Magnoliae Officinalis, its related Chinese Patent Medicines and their metabolites. However, the determination of these two analytes in a water-soluble sample is difficult and therefore requires a more efficient method.
 
  To develop a sensitive method for the determination of honokiol and magnolol in a water-soluble sample for better quality control of Cortex Magnoliae Officinalis and its related Chinese Patent Medicines.
 
  In this work, a combination of dispersive micro-solid-phase extraction (DMSPE) and high-performance liquid chromatography (HPLC) has been developed for simultaneous preconcentration and determination of honokiol and magnolol in complex bio-samples. Several experimental factors affecting the extraction efficiency were optimized by single factor test.
 
  Under the optimized extraction conditions, the proposed method exhibited good linearity of not less than 0.9998, satisfactory precision with relative standard deviation of less than 1.3%, and acceptable mean recoveries of 97.3% and 101.5% for honokiol and magnolol, respectively. Furthermore, the method exhibits extremely high sensitivity with detection limits of 0.0097 and 0.0231 ng/mL, which is even more sensitive than those methods developed by MS.
 
  The method established in this study is fast, economic, accurate, easy to operate, and importantly well suited to the extraction and analysis of honokiol and magnolol in a real complex sample matrix.
