Genome-wide characterization of MATE gene family and expression profiles in response to abiotic stresses in rice (Oryza sativa).

Multidrug and toxic compound extrusion (MATE) proteins are involved in many physiological functions of plant growth and development. Although an increasing number of MATE proteins have been identified, the understanding of MATE proteins is still very limited in rice. In this study, 46 MATE proteins were identified from the rice (Oryza sativa) genome by homology searches and domain prediction.

qTGW12a, a naturally varying QTL, regulates grain weight in rice.

A stable QTL associated with rice grain type with a large effect value was found in multiple environments, and its candidate genes were verified by genetic transformation. Rice (Oryza sativa L.) grain size is critical to both yield and appearance quality.

Identification of Floral Scent Profiles in Bearded Irises.

Bearded irises are ornamental plants with distinctive floral fragrance grown worldwide. To identify the floral scent profiles, twenty-seven accessions derived from three bearded iris, including , and were used to investigate the composition and relative contents of floral scent components by headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). A total of 219 floral scent components were detected in blooming flowers.

[Clinical features of unexpected sudden death clustered in 7 families in Yunnan Province].

Objective: To investigate the clinical features of unexpected sudden death (SUD) clustered in families in Yunnan province.

Methods: This retrospective study analyzed the clinical features of SUD occurred between July to September 2005 in 7 families in Yunnan province.

Results: All 16 SUD patients shared common clinical features such as fatigue and repeated syncope and one group of SUD patients (n = 8 from 4 families) presented with the gastric intestinal tract manifestations including nausea, vomiting, abdominal pain and diarrhea with suspected dietary history and abnormal laboratory enzyme findings (GOT/GPT, CK/CKMB, LDH/LDH1 etc.

Age-related effects of estrogen on the expression of estrogen receptor alpha and beta mRNA in the ovariectomized monkey hypothalamus.

In the present study, we reported distribution of ER alpha and ER beta mRNAs in the hypothalamus of young and old ovariectomized (OVX) rhesus macaques. The ER alpha were detected in all six major vestiblular nuclei which included arcuate nucleus (ARC) , paraventricularis nucleus (PVN) , periventricular nucleus (PeriV) , supraoptic nucleus (SON) , medial prioptic nucleus (MPN) and lateral hypothalamus area (LHA). However, the ER beta mRNA can also detected in those nuclei excerpt SON, but the signals of ER beta mRNA were weaker than those of ER alpha mRNA.

The use of flow cytometry to evaluate temporal changes in inflammatory cells following focal cerebral ischemia in mice.

Recent studies indicate that inflammation following cerebral ischemia contributes to neuronal damage. The local activation of resident cells and efficient recruitment of leukocytes into the central nervous system are critical steps in this inflammatory process. Here we describe studies using flow cytometry to examine the temporal pattern of inflammatory cell activation and infiltration following transient middle cerebral artery occlusion (MCAO) in mice.
