Objective: To report a new pest of Amomum villosum and its distribution, occurrence regularity and damage situation, in order to provide reference for its control.

Methods: Reared the pest larvae, observed the morphological characters, and made a preliminary investigation on its distribution, occurrence regularity and damage situation.

Results: Through macroscopic examination, the pest was identified as Anisodera rugulosa, which distributed in the main producing areas of Amomum villosum in Xishuangbanna, the pest larvae ate the inside of Amomum villosum fruit, which made the fruit formed holes, more seriously, it made the whole fruit rot black.

[Occurrence situation and control strategy of Dendrobium diseases in large-scale farming system].

Artificial cultivation medical Dendrobium flourished quickly and gradually developed in a streamlined production in large scale in Zhejiang, Yunnan, Anhui, Guizhou et al provinces in recent years. As the growing years being extended and area expanded, plant disease is a growing issue and became even worse. In the current review, we summarized the available studies and the investigation in those areas on disease kinds, regular patterns, area specificity, and prevention solutions and so on.

Functional SNPs in the SCGB3A2 promoter are associated with susceptibility to Graves' disease.

Graves' disease (GD) is one of the most common human autoimmune diseases, and recent data estimated a prevalence of clinical hyperthyroidism of 0.25-1.09% in the population.

Influence of visceral adiposity on ghrelin secretion and expression in rats during fasting.

Although circulating ghrelin levels correlate inversely with adiposity at baseline, little is known about the effect of percent visceral adipose tissue value (PVATV) on ghrelin expression and secretion in response to fasting. Our study demonstrated that ghrelin increased with 24-h fasting in rats with the lowest PVATV (less than 6%), after 3 days in rats with intermediate PVATV (6-9%) and 5 days in rats with the highest PVATV (greater than 9%). Ghrelin mRNA in the stomach was increased after 3 days in low-PVATV (5.

Effect of short-term and long-term fasting on transcriptional regulation of metabolic genes in rat tissues.

Ninety-eight genes/ESTs with differential expressions in epididymal adipose tissue of fed and 3-day fasting (F3) rats were identified by microarray analysis. Genes for lipogenesis, glycolysis, and glucose aerobic oxidation were decreased in response to starvation. Further study was performed to investigate the expression patterns of these genes in rat tissues after short- and long-term starvations.

The mimecan gene expressed in human pituitary and regulated by pituitary transcription factor-1 as a marker for diagnosing pituitary tumors.

Context: Mimecan, a secretory protein, belongs to a family of small leucine-rich proteoglycans (SLRPs). The physiological functions of mimecan have not been fully understood.

Objective: We hypothesize that the mimecan gene expressed in the human pituitary and regulated by pituitary transcription factor-1 (Pit-1) might act as a marker for diagnosing pituitary tumors.

Expression of feeding-related peptide receptors mRNA in GT1-7 cell line and roles of leptin and orexins in control of GnRH secretion.

Aim: To investigate the expression of feeding-related peptide receptors mRNA in GT1-7 cell line and roles of leptin and orexins in the control of GnRH secretion.

Methods: Receptors of bombesin3, cholecystokinin (CCK)-A, CCK-B, glucagon-like peptide (GLP)1, melanin-concentrating hormone (MCH)1, orexin1, orexin2, neuromedin-B, neuropeptide Y (NPY)1 and NPY5, neurotensin (NT)1, NT2, NT3, and leptin receptor long form mRNA in GT1-7 cells were detected by reversed transcriptase-polymerase chain reaction. GT1-7 cells were treated with leptin, orexin A and orexin B at a cohort of concentrations for different lengths of time, and GnRH in medium was determined by radioimmunoassay (RIA).

The gene expression profiling of human visceral adipose tissue and its secretory functions.

In order to fully understand the physiological functions of adipose tissue, especially its secretory functions, and to provide a basis for the identification of novel obesity related genes, the gene expression profiling of human visceral adipose tissue was established by using cDNA array. 33P-labelled cDNA, derived from visceral adipose tissue total RNA, was hybridized to a cDNA array containing over 16,000 expressed sequence-tagged clones which represent human singleton genes. The expressed sequence tag (EST) was considered to be expressed in visceral adipose tissue when the ratio of signal to noise was greater than or equal to 2.
