DNA identity is highly effective and efficient for distinguishing crop varieties regardless of their phenotypic similarities. To establish DNA identity in ramie, 21 simple sequence repeat primers were amplified in 108 accessions of domestic and exotic ramie germplasms. Sixty polymorphic bands were obtained, with an average of 2.9 bands per locus and 2-8 b.. Read More»

The glutathione S-transferase (GST) family consists of phase II detoxification enzymes that catalyze the conjugation of toxic substances, such as chemotherapeutic agents, to glutathione. We examined whether GSTT1/GSTT1“null”, GSTM1/GSTM1“null” and GSTP1Ile105Ile/GSTP1Ile105Val polymorphisms are associat.. Read More»

Orange-spotted grouper (Epinephelus coioides) is one of the most important marine fish and has a high market value. The insulin-like growth factor type 1 receptor (IGF1R) is a component of the insulin-like growth factor signaling system, and demonstrates important roles during growth. Based on information from livestock, we us.. Read More»

Growth hormone (GH) is a part of the somatotropic axis that controls metabolism, growth, development and aging in a wide range of animals. Mutations that reduce GH signaling have been associated with extended life spans and increased longevity in ways similar to what is observed in dietary restriction (DR) models. However, the..

This study investigated the correlation of plama levels of inflammatory biomarkers [soluble cluster of differentiation 40 ligand (sCD40L), alpha fetoprotein A (fetuin-A), and pregnancy-associated protein A (PAPP-A)] with carotid plaque in patients with acute ischemic stroke. After undergoing color Doppler ultrasonography of the bilateral carotid arteries,.. Read More»

A variety of anti-neuronal cell membrane antibodies such as voltage-gated potassium channel antibody, N-methyl-D-aspartate-2B-antibody, and glutamic acid decarboxylase antibody, are correlated with limbic encephalitis (LE). In this study on patients with LE, the clinical manifestations, psychology Wechsler Adult Intelligence Scale, cerebrospinal fluid, el.. Read More»

In a 17-kb genomic fragment of Trypanosoma cruzi chromosome XX, we identified three tandemly linked genes coding for CX2CX4HX4C zinc finger proteins. We also showed that similar genes are present in T. brucei and Leishmania major, sharing three monophyletic groups among these trypanosomatids. In T. cruzi, TcZFP8 corresponds to.. Read More»

Polymerase chain reaction of a pentanucleotide microsatellite in the U1 snRNA gene complex generated a multiple band pattern due to the priming of paralogous sequences. Denaturation and slow renaturation of polymerase chain reaction products allow the formation of heteroduplex DNA that can be detected by its differential mobil.. Read More»

A new species was synthesized artificially by chromosome doubling in a hybrid. The ensuing polyploid type exhibits an apomictic nature and maintains its morphological characteristics in the progeny. It showed a frequency of multiembryonic sacs of 29% in the ovules examined, whereas sacs were absent in the diploid type... Read More»

The stem structure of two cassava cultivars, UnB 99 and UnB 110, known for being adapted to humid conditions and tolerant to drought, respectively, and of a wild species, Manihot glaziovii, was examined anatomically. Free-hand sections of secondary stems were made, clarified with 50% sodium hypochlorite solution, stained with .. Read More»
