Phosphate (P) resources are expected to be depleted within a century. Therefore, promoting balanced phosphorus fertilizer use and understanding phosphorus dynamics in soils containing iron (III), organic acids, and iron (III)-organic molecule particulates is crucial. This study investigated the sorption of citric acid onto humic acid-iron hydr(o)xide coprecipitate (HAFHCP) and the reciprocal effects of citric acid and P sorption on HAFHCP with different C/Fe ratios.

Precipitation of Fe-hydroxide (FH) critically influences the sequestration of PO and organic matter (OM). While coatings of pre-sorbed OM block FH surfaces and decrease the PO adsorption capacity, little is known about how OM/Fe coprecipitation influences the PO adsorption. We aimed to determine the PO adsorption behaviors on humic acid (HA)-Fe coprecipitates in relation to surface and structural characteristics as affected by HA types and C/(C + Fe) ratios using the Fe and P X-ray absorption spectroscopy.

Background/purpose: To investigate the M1/M2 polarity of macrophages in the endometrium among different menstrual cycles, normal and abnormal pregnancies, and unexplained recurrent spontaneous abortions (RSAs).

Methods: Endometrial tissue was obtained from 43 patients undergoing hysterectomy, either in the follicular phase (Group 1, n = 23) or in the luteal phase (Group 2, n = 20). In addition, decidual tissue was obtained from 53 pregnant women during the first trimester, either of normal pregnancies (Group 3, n = 12) or abnormal pregnancies (Group 4: spontaneous abortions, n = 20; Group 5: unexplained RSA, n = 21).
