By employing molecular modeling of interaction simulation combined with a confirmatory yeast two-hybrid analysis, we identified the Raptor-binding region in an ABA receptor PYL1 protein of Arabidopsis. click here The region was a part of the C-terminal alpha-helix structure of the protein within which a phenylalanine and an aspartate in the sequence of FADTV are predicted to form critical interactions with the Raptor. Although the sequence deviates a little from the plant TOS consensus that we previously identified and defined (FSD [V/I]F) from AtS6Ks and its orthologues as well as AtATG13, the modeling data indicate that the sequence and its neighboring area are structurally capable of establishing the interaction with the Raptor in the same mode as those of other TOS motif-containing structures. This finding provides a new insight into the understanding of plant TOS motif, based upon which a putative Raptor-binding region in TAP46, another TOR substrate, is proposed.

Neuropathic pain (NPP) is a common clinical symptom, its pathological mechanism is complex, and there is currently no good treatment method. Therefore, exploring the treatment method of NPP is a critical issue that needs to be urgently solved.

Neural stem cells (NSC) and microencapsulated neural stem cells (MC-NSC) were transplanted into the site of sciatic nerve injury, and behavioral methods were used to detect changes in pain. Expression levels of P2X7R were detected in the dorsal root ganglion (DRG) by molecular biological methods.

After sciatic nerve injury, mechanical withdrawal thresholds (MWT) and thermal withdrawal latency (TWL) of rats were significantly reduced, the expression levels of P2X7R in the DRG were significantly increased. After transplantation of NSC and MC-NSC, it was found that expression levels of P2X7R were significantly reduced and pain was significantly suppressed. Importantly, compared with NSC transplantation, MC-NSC could better reduce the expression levels of P2X7R and inhibit pain.

MC-NSC can better decrease the expression levels of P2X7R and relieve NPP. Our results provide a novel method and data support for the treatment of NPP.

To determine whether body mass index (BMI) affects intrauterine insemination treatment success.

Retrospective cohort study.

Academic medical center.

A total of 3,217 intrauterine insemination treatment cycles in 1,306 patients.

None.

Primary outcome was live birth rate stratified by BMI. Secondary outcomes included rates of clinical pregnancy (defined as an intrauterine pregnancy with a heartbeat present on ultrasound), multiple gestation, biochemical pregnancy, missed abortion, ectopic, and spontaneous abortion.

Women with BMI 25 to 29.99 kg/m

or ≥30 kg/m

were equally likely to have a live birth as women of normal BMI. Women with BMI ≥30 kg/m

did have a higher likelihood of biochemical pregnancy than women with normal BMI.

A BMI between 25 and 29.99 kg/m

or ≥30 kg/m

does not appear to have a negative effect on live birth after intrauterine insemination. Obesity may be associated with a higher risk of biochemical pregnancy after intrauterine insemination.

To determine the expression and functional roles of a long noncoding RNA (lncRNA) X-inactive specific transcript (XIST) in leiomyoma.

Experimental study.

Academic research laboratory.

Women undergoing hysterectomy for leiomyoma.

Overexpression and underexpression of XIST; blockade of specific protein 1 (SP1).

Expression of XIST in leiomyoma and its effects on microRNA 29c (miR-29c), miR-200c, and their targets.

Leiomyoma expressed statistically significantly more XIST as compared with matched myometrium, independent of race/ethnicity and menstrual cycle phase. By use of a three-dimensional spheroid culture system, we found reduced XIST levels in leiomyoma smooth muscle cells (LSMC) after treatment with 17β-estradiol, progesterone, and their combination. The expression of XIST was down-regulated by treatment with the SP1-inhibitor mithramycin A and SP1 small interfering RNA. Knockdown of XIST resulted in inhibition of cell proliferation, up-regulation of miR-29c and miR-200c, and a concomitant inracellular matrix accumulation associated with fibroids.

To examine the association between plasma glycemia in women attempting to conceive and fecundability, as measured by time to pregnancy.

Prospective preconception population-based study.

Hospital.

Asian preconception women, 18-45 years old, attempting conception for ≤12 cycles at study entry.

None.

We ascertained time to pregnancy within a year of glycemic assessment in menstrual cycles. We estimated fecundability ratios (FRs) and 95% confidence intervals using discrete-time proportional hazards models, adjusting for age, ethnicity, education, body mass index, and cycle regularity and accounting for left truncation and right censoring.

We studied a population sample of 766 women from the Singapore Preconception Study of Long-Term Maternal and Child Outcomes prospective cohort. Compared with women with normoglycemia, women with dysglycemia (prediabetes and diabetes, defined by the American Diabetes Association) had a lower FR (0.56). Compared with the respective lowest quintiles, women in the highest quintile of fasting glucose (≥5.1 mmol/L) had an FR of 0.60, while women in the highest 2-hour postload glucose quintile (≥6.9 mmol/L) had an FR of 0.66. Overall, the FRs decreased generally across the range of fasting and 2-hour plasma glucose. Glycated hemoglobin was not associated with fecundability.

Increasing preconception plasma glucose is associated with reduced fecundability, even within the normal range of glucose concentrations.

To study the experiences, considerations, and motivations of patients with endometriosis in the decision-making process for deep endometriosis (DE) treatment options.

Qualitative study using semi-structured in-depth focus group methodology.

University medical center.

A total of 19 Dutch women diagnosed with DE between 27 and 47 years of age.

Not applicable.

Focus group topics were disease impact and motives for treatment, expectations of the treatment process, and important factors in the decision process.

Women reported that pain, fertility, and strong fear of complications are important decisive factors in the treatment process. The goal of conceiving a child is considered important, however, sometimes doctors emphasize this topic too much. It emerged that complication counseling is frequently about surgical complications, whereas side effects of hormonal treatments are neglected. Shared decision making and information about treatment options, complications, and side effects are not always optimal, making it difficult to make a well-considered choice.
