Soluble fms-like tyrosine kinase 1 and placental growth factor ratio for predicting preeclampsia in elderly gravida

Objective To determine the predictive value of plasma soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF) ratio for detection of preeclampsia in elderly gravida at 16–18 weeks of gestation and to identify whether abnormalities of this ratio are associated with any other pregnancy complications or not. Methods Blood samples of 300 cases were collected. Plasma sFlt-1 and PlGF levels were measured using an automated immunoassay. Results  Sensitivity and specificity for plasma sFlt-1/PlGF ratio above 9.8 for preeclampsia prediction were 85.7% and 61.2%, respectively. The sensitivity and specificity to predict early onset preeclampsia were 100% and 61.1%, respectively. Women with abnormal plasma sFlt-1/PlGF ratio were not associated with any other pregnancy complications. Conclusion  sFlt-1/PlGF ratio at 16–18 weeks of gestation in elderly gravida has a high sensitivity for predicting preeclampsia, especially early onset preeclampsia

Four new species of troglomorphic Coecobrya Yosii, 1956 (Collembola, Entomobryidae) from Thailand based on morphological and molecular evidence, with an updated key of Thai troglomorphic species

Four new species of troglomorphic Coecobrya Yosii, 1956 are described from caves located in the central and northeastern regions of Thailand. Coecobrya whitteni sp. nov. and C. troglobia sp. nov. are from Khon Kaen province, C. ellisi sp. nov. is from Phetchabun province and C. phitsanulokensis sp. nov. is from Phitsanulok province. They all exhibit remarkable troglobitic characters i.e. elongated antennae, legs and furca, slender claw complex and large body size. Coecobrya whitteni sp. nov. is similar to C. troglobia sp. nov. and they were found a distance of only 3.4 km from each other. However, they are mainly different in the number of An mac on dorsal head and number of chaetae of Th. II. Likewise, C. ellisi sp. nov. is similar to C. phitsanulokensis sp. nov.. However, they differ in the number of An mac on the dorsal head, the number of central mac on Abd. II, central mac on Abd. IV, lateral mac on Abd. IV and the number of inner teeth of the claw. Moreover, C. ellisi sp. nov. has orange pigment dots on the body, a unique character, considering that all other troglomorphic Coecobrya species in Thailand are devoid of pigmentation. The results of the molecular approach based on two partial mitochondrial markers (COI and 16S rDNA) and a nuclear gene fragment (28S rDNA) supported the results of morphological species discrimination in separating the four nominal populations as valid species. An updated dichotomous key of Thai troglomorphic Coecobrya species is also given

Systematics of Lepidocyrtinus boneti Denis, 1948 (Collembola, Seirinae) reveals a new position for the species within Seirinae

Seira boneti Denis, 1948, comb. nov. is examined and redescribed based on syntypes and by a newly discovered Chinese population. Lectotype and paralectotypes were designated, and the type locality of the species has been fixed to Câuda, near Nhatrang, Vietnam. The species was first described in the genus Lepidocyrtinus, but based on morphological and molecular evidence it is here transferred to Seira. For the phylogenetic placement of Seira boneti comb. nov., its mitogenome was included in a dataset comprising 19 species of Seirinae. Maximum Likelihood and Bayesian inferences clustered the species next to Seira sanloemensis Godeiro & Cipola, 2020 from Cambodia, forming a distinct Seira clade from the Old World, confirming the hypothesis of the existence of a different basal lineage of Seirinae in Southern Asia
