To study the relationship between gastrointestinal dysfunction and motilin in patients with hypothyroidism. The plasma motilin
concentration was measured by radiommunoassay (RIA) in 30 patients with hypothyroidism and also in 30 controls. At the same
time, the electrogastroenterogram was also taken. Among the hypothyroidism patients, 56.6% had decreased gastric motility,
especially in gastric body and greater gastric curvature; 86.6% had decreased colonic motility, especially in the left half
of the colon. There were no significant differences of plasma motilin concentration between patients with hypothyroidism and
controls (P>0.05). There were also no differences between pre-treatment and post-treatment individuals, but significant differences were
observed in the electrogastroenterogram. We conclude that the plasma motilin concertration in hypothyroidism patients was
the same as that in normal patients, and that electrogastroenterogram studies in patients with gastrointestinal dysfunction
may be valuable. 相似文献

In this study, we produced tomato plants overexpressing an invertase inhibitor gene (Sly-INH) from tomato, using a simple and efficient transient transformation system. Compared with control plants, the expression of Sly-INH was highly upregulated in Sly-INH overexpressing plants, as indicated by real-time polymerase chain reaction (PCR). Physiological analysis revealed that Sly-INH inhibited the activity of cell wall invertase (CWIN), which increased sugar accumulation in tomato fruit. Furthermore, Sly-INH mediated sucrose metabolism by regulating CWIN activity. Our results suggest that invertase activity is potentially regulated by the Sly-INH inhibitor at the post-translational level, and they demonstrate that the transient transformation system is an effective method for determining the functions of genes in tomato. 相似文献

The implications of subclinical hypothyroidism (SCH) are many amongst which the most important is progression to overt hypothyroidism. Other debatable aspects are its association with cardiovascular risk, neuromuscular and psychiatric dysfunction, increased predisposition to developing metabolic syndrome and an underlying pro-inflammatory state. We aimed to study the lipid profile, lipoprotein(a) [Lp(a)] and hsCRP levels and insulin resistance in a group of patients with SCH in a referral hospital and see if any significant differences exist between them and euthyroids. This is a case–control study where the selection of controls and cases was based on the thyroid profile. Subjects were selected on their visit to clinical biochemistry lab for thyroid function tests. 33 euthyroids were taken as controls (Group I) and 38 patients comprising of subclinical hypothyroids were grouped as cases (Group II). Serum thyroid stimulating hormone (TSH) was in the range of 0.5–5.0 mIU/L for euthyroids and for subclinical hypothyroids the concentration of TSH was more than 5 mIU/L. The concentration of tri-iodothyronine (T3) and thyroxine (T4) were in normal reference range in both the groups. Individual lipid profile parameters failed to show a significant p value between cases and controls. The LDL/HDL ratio was highly significant (p value < 0.0001) and hsCRP was also statistically between the two groups (p value = 0.0054). Lp(a) and insulin resistance did not differ significantly. SCH is a common disorder that frequently progresses to overt hypothyroidism. This study underlines the importance of LDL/HDL ratio rather than measurement of individual lipid profile parameters in bringing to light the dyslipidemic state associated with SCH. Moreover the use of hsCRP to detect an underlying pro-inflammatory state in SCH can also be emphasized. 相似文献

Highly mobile students experience schools and learning in different ways than their more stable peers. Repeated transfers
result in discontinuity of instruction and relationships with teachers and peers. Interviews with transient urban students
in grades 9–12 reveal the issues they face upon their arrival and afterward. Mobile students give insight into perceptions
of teacher practice, peer-group induction, receptivity to classroom instruction, and classroom and administrative practices.
Findings include fear, loneliness, embarrassment, and anxiety in new settings or when faced with another school change. While
students expressed achievement concerns, peer social and emotional concerns were primary immediately following enrollment
in a new school. Students found themselves unable to focus on academic studies until they could secure a peer group with which
to interact. Implications for high-mobility schools include the need for structures providing transitional services and community-building
environments to counteract the negative academic and developmental effects of frequent mobility. 相似文献

Research on Self-Determination Theory has shown that teachers’ need-supportive behaviour is associated with student motivation and engagement. The purpose of this study is to examine the effectiveness of an intervention aimed at increasing the motivation of students with congenital and acquired deafblindness by enhancing teachers’ need-supportive behaviour. To assess the intervention effect, this study follows a multiple case-study design. Teacher questionnaires were administered and video observations of teacher–student interactions were made during pre-test, post-test and follow-up phases. The results showed that teachers provided involvement most, followed by structure and autonomy support. Teachers’ provision of structure and autonomy seems to improve most after the intervention. In general, teachers of students with congenital deafblindness showed larger intervention effects than teachers of students with acquired deafblindness. The results also provide indications that students’ levels of engagement improved after the intervention. 相似文献
