Cytogenetic study and stripe rust response of the derivatives from a wheat - Thinopyrum intermedium - Psathyrostachys huashanica trigeneric hybrid.

To transfer multiple desirable alien genes into common wheat, we previously reported a new trigeneric hybrid synthesized by crossing a wheat - Thinopyrum intermedium partial amphiploid with wheat - Psathyrostachys huashanica amphiploid. Here, the meiotic behavior, chromosome constitution, and stripe rust resistance of F derivatives from the wheat - Th. intermedium - P.

Cytogenetic Behavior of Trigeneric Hybrid Progeny Involving Wheat, Rye and Psathyrostachys huashanica.

Trigeneric hybrids are commonly used as bridges to transfer genes from some wild species to cultivated wheat and to measure the genomic interaction between donor species. We previously reported that trigeneric germplasms were produced by crossing wheat-Psathyrostachys huashanica amphiploids (PHW-SA, 2n = 8x = 56, AABBDDNsNs) with hexaploid triticale (Zhongsi 828, 2n = 6x = 42, AABBRR). In the present study, chromosome pairing behavior and the genome constitution of the F4 progenies of wheat-rye-P.

[Review: plant polyphenols modulate lipid metabolism and related molecular mechanism].

Lipid metabolism disorder is an important risk factor to obesity, hyperlipidemia and type 2 diabetes as well as other chronic metabolic disease. It is also a key target in preventing metabolic syndrome, chronic disease prevention. Plant polyphenol plays an important role in maintaining or improving lipid profile in a variety of ways.

Characterization of wheat - Psathyrostachys huashanica small segment translocation line with enhanced kernels per spike and stripe rust resistance.

Psathyrostachys huashanica Keng (2n = 2x = 14, NsNs), a distant wild relative of common wheat, possesses rich potentially valuable traits, such as disease resistance and more spikelets and kernels per spike, that could be useful for wheat genetic improvement. Development of wheat - P. huashanica translocation lines will facilitate its practical utilization in wheat breeding.

[Effects of endoplasmic reticulum stress related proteins and their mediated apoptosis in the formation of deep tissue injury of pressure ulcer in rats].

Objective: To explore the effects of endoplasmic reticulum stress (ERS) related proteins and their mediated apoptosis in the formation of deep tissue injury of pressure ulcer in rats.

Methods: Forty male Sprague-Dawley rats were divided into normal control group and groups A, B, C, D according to the random number table, with 8 rats in each group. Rats in group A were loaded with 22.

[Expressions of vascular endothelial growth factor and basic fibroblast growth factor in the late stage of pressure ulcer].

Objective: To study the distribution and expressions of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in the III-IV stage of pressure ulcer wound, and to explore their correlation with ulceration.

Methods: Forty-one patients hospitalized in the two Affiliated Hospital of Wenzhou Medical College from June 2010 to March 2012 were recruited, including twenty-one patients with 23 pressure ulcer of stage III-IV, 14 acute injury patients, and 6 donors of normal skin. Samples harvested from the 41 patients through surgery were divided into four groups, including pressure ulcer centre group (n = 23), pressure ulcer margin group (n = 23), acute wound group (n = 14), and normal skin group (n = 6).

Ocular manifestations of intracranial germinomas: three cases report and literature review.

Intracranial germinomas are malignant neoplasms of gonadal origin, which have some features in terms of age, sex, and clinical manifestations. They mainly occur in children and adolescents. Patients with intracranial germinomas mainly manifest with hypothalamic pituitary axis dysfunction and/or compression syndromes.
