Sex Education through a Trauma-Informed Lens: Do Parents Who See Trauma as a Problem for Youth Support Trauma-Informed Sex Education?

Trauma-informed sex education is sensitive to students’ traumatic life experiences. Internet panel data for 600 Louisiana parents/caregivers of school-age youth were used to examine parental support for trauma-informed school-based sex education, and parental characteristics associated with supporting trauma-informed sex education. Nearly three-quarters (71%) of parents agreed that youth are exposed to high levels of trauma, and 86% reported interest in school-based sex education that supports emotional wellness. Of all parental characteristics, the perception that youth are exposed to high levels of trauma was most strongly associated with endorsement of trauma-informed sex education. Louisiana parents recognize the influence of emotional wellness on youth sexual health and support trauma-informed school-based sex education, which is becoming the new standard for youth sex education services.

A sex education programme for mothers in Iran: Does preschool children’s sex education influence mothers’ knowledge and attitudes?

Mothers have an important role to play in teaching their children about sexual issues and shaping children’s sexual knowledge, attitudes and behaviours. In many cases, however, mothers themselves need help and support. This study was conducted to examine the effects of a sex education programme on the knowledge and attitudes of the mothers of pre-school children. Eighty mothers of pre-school children were randomly divided into an experimental and a control group. The experimental group received an education and training programme delivered over two 2-h sessions. The control group received no such intervention. Researcher-constructed knowledge and attitude questionnaires were completed by both groups before and one month after the intervention. Findings showed no significant differences between the two groups in terms of knowledge and attitudes before the training. After the education and training intervention, however, there was a significant increase in the mean score for both knowledge and attitudes in the experimental group compared to the control group. Study findings suggest that the sex education programme for the mothers of pre-school children can improve their knowledge and attitudes.     

林克霉素发酵中生物氮素的替代应用

使用生物氮素替代林可霉素发酵培养基中黄豆饼粉。摇瓶结果显示,不同的替代比例对林可霉素发酵的影响大不相同。合适的替代比例可以改善发酵中后期的菌丝形态,大幅提高发酵水平。在50L发酵罐,使用生物氮素替代40％的黄豆饼粉,可以提高发酵效价9．79％。生物氮素质量稳定,且有一定的相对价格优势,在林可霉素发酵生产上有着不错的应用前景。

Expression of a fusion protein of human ciliary neurotrophic factor and soluble CNTF-Receptor and identification of its activity

Ciliary neurotrophic factor (CNTF) has pleiotropic actions on many neuronal populations as well as on glia. Signal transduction by CNTF requires that it bind first to CNTF-R, permitting the recruitment of gp130 and LIF-R, forming a tripartite receptor complex. Cells that only express gp130 and LIF-R, but not CNTF-R are refractory to stimulation by CNTF. On many target cells CNTF only acts in the presence of its specific agonistic soluble receptors. We engineered a soluble fusion protein by linking the COOH-terminus of sCNTF-R to the NH₂-terminus of CNTF. Recombinant CNTF/sCNTF-R fusion protein (Hyper-CNTF) was successfully expressed in COS-7 cells. The apparent molecular mass of the Hyper-CNTF protein was estimated from western blots to be 75 kDa. Proliferation assays of transfected BAF/3 cells in response to CNTF and Hyper-CNTF were used to verify the activity of the cytokines. The proliferative results confirmed that CNTF required homodimerization of the gp130, CNTF-R and LIF-R receptor subunit whereas Hyper-CNTF required heterodimerization of the gp130 and LIF-R receptor subunit. We concluded that the fusion protein Hyper-CNTF had superagonistic activity on target cells expressing gp130 and LIF-R, but lacking membrane-bound CNTF-R.
