Several studies have shown an imbalance between proinflammatory and anti-inflammatory cytokines in depression and anxiety disorders. However, less attention has been paid to the role of cytokines in psychological disorder in mothers who breastfeed. This study looks at whether concentration levels of TGF-β2 are altered in anxious and depressive breastfeeding mothers. This study checked the concentration level of TGF-B2 in relation with psychological symptoms on 110 breastfeeding mothers; based on random sampling method with using of Beck Depression Inventory (BDI), General Health Questionnaire (GHQ) and Spielberger Stress Scale (STAI) in 2015 also TGF-β2 was measured in breast milk using ELISA...

Since the sequential extraction of phosphorus (P) in sediment makes it possible to determine the P potentially available for release, in this paper, we evaluate the fractions of P in sediment profiles from Valle de Bravo reservoir, a eutrophic lake in central Mexico to determine the contributions of each fraction to the internal P load (IPL). The P fractionation scheme employs sequential extractions of sediment with O2-free water (MilliQ), bicarbonate-dithionite (BD), sodium hydroxide (NaOH), hydrochloric acid (HCl), and potassium persulfate (K2S2O8-) to obtain five P fractions...

Brain metastasis is a common complication in advanced systemic cancer, with an increasing incidence. The diagnosis of brain metastasis historically portended a dismal prognosis. The successful development of effective treatments for patients with brain metastasis is complicated by the differences among cancer subtypes, the limited understanding of the underlying pathophysiology of BM, the impact of the blood-brain barrier, and other factors. There is now renewed interest in treating this often devastating complication of cancer, and in understanding the underlying mechanisms of disease in this "sanctuary" site...

The muscle regulatory transcription factor MyoD is a master regulator of skeletal myoblast differentiation. We have previously reported that MyoD is also necessary for the elevated expression of the pro-apoptotic Bcl2 family member PUMA, and the ensuing apoptosis, that occurs in a subset of myoblasts induced to differentiate. Herein, we report the identification of a functional MyoD binding site within the extended PUMA promoter. In silico analysis of the murine PUMA extended promoter revealed three potential MyoD binding sites within 2 kb of the transcription start site...

PURPOSE: Quadriceps femoris (QF) strength deficits at return-to-sport (RTS) after ACL reconstruction (ACLR) contribute to decreased knee function at the same time point. However, the impact of QF strength at RTS on longitudinal function has not been examined. The purpose of this study was to test the hypothesis that young athletes after ACLR with QF strength asymmetry at RTS would demonstrate decreased knee-related function and lower proportions of functional recovery at 1 year post-RTS compared to young athletes following ACLR with nearly symmetric QF strength at RTS...
