发育激素

Recently insulin like hormone 3 is a hotspot of concerning affecting gubernacular development and testicular descent.

胰岛素样激素3是近年来倍受关注的影响睾丸引带发育和睾丸下降的重要因素，本文就相关进展进行综述。

The cause of hindering the gynospore formation was short of boronin chestnut orchard,which led to the poor pollination and a decrease ofendogenous GA1/3, iPAs level and an increase of endogenous ABA level in ovary,which restrained the mother cell division of gynospore.The low level ofendogenous GA1/3,iPAs contents and the increase of endogenous ABA contentcaused a serious lack of reducing sugar,starch,protein and potassium in ovary,which led to a cease of young embryo development.

其中，大孢子形成过程的停滞是由于栗园B素缺乏，致使授粉不良和子房内源GA1/3、iPAS等含量下降，ABA含量上升，从而抑制大孢子母细胞分裂；幼胚发育停滞则是由于子房内源GA1/3、iPAS等生长类激素的上升启动受阻，继续处于低水平，ABA上升，使子房中还原糖、淀粉、蛋白质和K素积累受阻，造成营养严重缺乏。

Therefore,foliar spraying ofboron was the main measure during flowering period so as to stimulate thegermination and growth of pollen tube,regulate endogenous hormone balance ofovary and promote gynospore formation and,during the phase of young embryodevelopment,spraying of relevant plant growth regulators and potassiumsupplement were essential to stimulating the increasing of endogenous GA1/3 andiPAs,raising the key nutritious substance content in ovary and promoting youngembryo development.

因而花期调节以喷B为主，以便促进花粉管萌发生长，调节子房内源激素平衡，促进大孢子形成；幼胚发育期以植物生长调节剂喷布和K素补充为主，以便启动子房内源GA1/3、iPAS等上升，增加还原糖、淀粉、蛋白质积累和K素吸收，促进幼胚发育。

Covers cells and tissues of the immune system, lymphocyte development, the structure and function of antigen receptors, the cell biology of antigen processing and presentation including molecular structure and assembly of MHC molecules, the biology of cytokines, leukocyte-endothelial interactions, and the pathogenesis of immunologically mediated diseases.

课程涵盖免疫系统的细胞和组织，淋巴球的发育过程，抗原受体的结构和功能，抗原反应过程的细胞生物学以及抗原的呈现，其中包括MHC分子的结构与组合，细胞激素的生物学，白血球和内皮组织的互动关系，以及免疫相关疾病的致病机转。

The 1000-grain weight heterosis was mainly due to the grain fresh weight heterosis at 12 DPA and 22 DPA that the intervarietal hybrid had, and also due to its promotion of 2 kinds of hormone IAA and CTK 12 DPA, the IAA function extended to 22 DPA.

品种间杂种也具有一定的千粒重杂种优势，这与12天、22天籽粒的鲜重优势有关，籽粒发育早期（12天）2种促进型激素IAA和CTK促进籽粒生长，与其获得较大的鲜重优势有关，IAA的促进作用可延伸到22天。

Insect alkaline phosphatases are distributed in such insect organs and tissues as head, salivary gland, intestine, Malpighian tube cuticule, haemolymph, fat body, reproductive system and appendage. They may be involved in the process of insect development, nerve conduction, hormone synthesis, substance metabolism and diapause, and caste formation in social insects, etc.

碱性磷酸酶存在于昆虫的头、唾液腺、肠道、马氏管、表皮、血淋巴、脂肪体、生殖系统、附肢等部位，广泛参与了昆虫的发育、神经传导、激素合成、物质代谢、滞育、社会型昆虫亚种形成等过程。

Meanwhile to explore the influence of psychosocial stress factors on oocyte maturity, the number of retrieved oocytes and merogenesis, the plasma levels of A and NA and the follicular fluid levels of NA, estrogen and androgen were examined in pregnant and non-pregnant women.

并通过对妊娠与未妊娠妇女血浆中A、NA及卵泡液中NA、雌激素、雄激素水平测定，结合获卵数和卵裂数进行相关性研究探讨心理社会因素对卵泡发育成熟的影响。

Infant boys with idiopathic or isolated hypogonadotropic hypogonadism that is congenital (i.e., present at birth) often have micropenis and cryptorchidism.

先天具有自发的或单纯性促性腺激素分泌不足性腺机能减退的男婴常常有阴茎发育不良和隐睾病。

In addition, it also leads to the increase of T〓 and FT〓 content, the decrease of T〓 and FT〓 content, the increase of TSH content in the plasma, which seriously influences the whole body's growth and metabolism of nutrimental materials and is one of the mechnism of nutritional anemia that is caused by lack of matter of making blood.

首次揭示雏鸡硒缺乏不但对甲状腺造成损伤，而且还特异性地降低肝脏、肾脏等组织中ID-1活性，使血浆3-5-3'-5'-四碘甲状腺原氨酸、游离T〓含量升高，3-5-3'-三碘甲状腺原氨酸、游离T〓含量下降，促甲状腺激素含量升高，严重影响整个机体的生长发育及营养物质代谢，并是导致造血物质缺乏所致的营养性贫血的机理之一。

The levels of serum gonadal hormone were detected by radioimmunoassay. The effects of ZYJN on ovaries and ovarial follicular development were observed by light microscope. The expressed level of LIF was detected by using the immunohistochemical staining technique.

随机分为对照组、PCO模型组、PCO模型组＋助孕胶囊组、PCO模型组＋克罗米酚组，采用放免法测定血性激素水平的变化，光镜观察卵巢、卵泡发育的情况，免疫组化法检测卵巢组织LIF的表达水平。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
