The changing profiles of L-ornithine decarboxylase and S-adenosyl-L-methionine decarboxylase activities in testicular cell types during sexual maturation of male rats
L-ornithine decarboxylase S-adenosyl-L-methionine testicular cell types
2009/2/23
To understand the involvement of polyamines in testicular maturation and spermatogenesis, the activity of two enzymes involved in the polyamine synthetic pathway, L-ornithine decarboxylase (ODC) a...
Control of Rat Testicular Prostaglandin Dehydrogenase, 13-Prostaglandin Reductase, and Total Prostaglandin Dehydrogenase Activities
rat testicular prostaglandin dehydrogenase hypophysectomy luteinizing hormone follicle stimulating hormone
2009/2/19
The effects of hypophysectomy and various hormonal treatments on rat testicular prostaglandin dehydrogenase (PGDH), 13-PG reductase, and total PGDH activities were studied in vivo and in vitro. Al...
Motility potential of macaque epididymal sperm: the role of protein phosphatase and glycogen synthase kinase-3 activities
Monkey spermatozoa enzymes caput caudal
2009/2/18
Human and monkey ejaculated sperm contain protein phosphatase-1 (PP1), PP1 inhibitor 2 (12), and glycogen synthase kinase-3 (GSK-3). Inhibition of ejaculated human sperm protein phosphatase (PP) a...
Protein kinase CK2 activities in human prostatic and seminal-vesicle secretions and seminal plasma
Prostate vasectomy normozoospermia oligozoospermia
2009/2/18
Human prostatic secretion and seminal plasma contain certain protein kinase activities. Protein kinases play important roles in regulating a vast variety of cellular functions. The objective of this...
Lipid peroxidation and antioxidant enzyme activities in the rat testis after cigarette smoke inhalation or administration of polychlorinated biphenyls or polychlorinated naphthalenes
Reactive oxygen oxidative stress superoxide dismutase catalase cigarette smoking environmental chemicals
2009/2/12
Lipid peroxidation products and antioxidant enzyme activities were studied in the rat testis following exposures to cigarette smoke, polychlorinated biphenyls (PCBs), or polychlorinated naphthalen...
Acute immobilization stress disrupts testicular steroidogenesis in adult male rats by inhibiting the activities of 17 alpha-hydroxylase and 17,20-lyase without affecting the binding of LH/hCG receptors
Stress rats testosterone 17a-hydroxylase
2009/2/12
We have investigated the effect of acute immobilization (3 hours) stress on testicular steroidogenesis in the adult rat. Immobilization did not alter plasma luteizing hormone (LH) levels, but plas...
Differential effects of FSH on the activities of S-adenosyl-L-methionine decarboxylase and ornithine decarboxylase in Rat sertoli cells
Sertoli cells ODC AdoMetDC FSH
2009/2/6
Follicle stimulating hormone (FSH) modulates testicular function via Sertoli cells. The effect of FSH on S-adenosyl-L-methionine decarboxylase (AdoMetDC) activity was investigated in cultured Sert...
Enolase isoforms activities in spermatozoa from men with normospermia and abnormospermia
Human sperm glycolytic enzyme Percoll gradient enzyme marker sperm immaturity
2008/12/30
Total enolase as well as enolase-alphaalpha. (ENO-alphaalpha, ubiquitous) and enolase-S (ENO-S, sperm-specific) activities were measured in total and Percoll-selected sperm from 30 normospermic fert...
Dipeptidylpeptidase IV activities are elevated in prostate cancers and adjacent benign hyperplastic glands
Dipeptidylpeptidase IV activities prostate cancers hyperplastic glands
2008/12/25
Dipeptidylpeptidase IV (DPP IV) is a serine exopeptidase that has been implicated in cell-extracellular matrix interactions and bioactive peptide/cytokine/growth factor metabolism. The objective o...
Enolase isoforms activities in spermatozoa from men with normospermia and abnormospermia
Enolase isoforms activities spermatozoa men normospermia abnormospermia
2008/12/2
Total enolase as well as enolase-alphaalpha. (ENO-alphaalpha, ubiquitous) and enolase-S (ENO-S, sperm-specific) activities were measured in total and Percoll-selected sperm from 30 normospermic fert...
这个概念是指：在法律不禁止的范围内，个人具有按照自己的意愿来选择和决定自己在性方面的一切事务的权利。他人不得侵害或者破坏个人的这种权利。
性的自主权存在于性关系、性行为和性表现这三大方面之中。
性的自主权首先是指个人的自主选择权。在性关系方面，个人有权按照自己的独立意愿，不受他人干涉地建立、维持或者终止某个性关系，或者拒绝建立、维持或者终止某个性关系。在中国，这方面的个人自主权主要反映在...
性权利（rights in sexual activities）
性权利
2008/4/16
权利是指主体能够作出或者不作出一定行为，以及其要求他人相应做出或不作出一定行为的许可与保障。性权利就是指个人主体在性关系和性活动中所拥有的这种许可与保障。一般来说，性权利应该由法律确认和设定，并为法律所保护。当权利受到侵害时，国家应依法施用强制手段予以恢复，或使享有权利者得到相应补偿。离开法律确认和保护、无所谓性权利的存在。但是在目前的社会中，由于人们在思想和观念上还没有充分认识到性权利的重要性...
