Thin slices of human ovarian cortex were evaluated following cryopreservation in 1,2-propanediol (PROH)/sucrose under various conditions. Following rapid thawing, 1 microm sections were assessed by light microscopy and oocyte abnormalities were further examined by electron microscopy. Follicles (n = 503) were predominantly primordial (91%), with no follicles larger than the proliferating primar...
The present study was purported to standardize the high-resolution respirometry technique for the analysis of oxidative phosphorylation (OXPHOS) in saponin-skinned cardiac fibers. Preparation of permeabilized myocardial fibers allows the assessment of respiratory function of the entire population of mitochondria in their normal intracellular position. Adult male rat ventricular bundles were per...
Genetic manipulation for "knockout" (KO) is a useful tool for characterizing a target gene. However, its shortcomings that need to be overcome hinder its easy and ready usage in ordinary laboratories. Here we describe a knockdown technique termed the RNA interference (RNAi)-induced gene silencing by local electroporation (RISLE). Small interfering RNA (siRNA) introduction by electroporation int...
Escherichia coli O26 is the most important serotype in non-O157 group, which plays a significant role in gastrointestinal illnesses. However, information regarding the prevalence and its characteristics are lacking in Thailand. As raw meat is frequently a source of diarrheagenic E. coli, a total of 1,279 E. coli colonies were obtained from 157 raw meat samples obtained from retail markets in Ha...
Behavioral and electrophysiological manifestations occurring under conditions of spatial discontiguity of CS and reinforcement (or response) are described. It is concluded that the conflict or learning difficulties which arise in such situations are the result of a competition between the signal directed conditioned orienting response and the goal directed approach response which require differ...
Neurobiological models propose an evolutionary, vertical-integrative perspective on emotion and behavior regulation, which postulates that regulatory functions are processed along three core brain systems: the brainstem, limbic, and cortical systems. To date, few developmental studies applied these models to research on prenatal and perinatal risk. We propose a conceptual model that incorporate...
This paper deals with the study of formation of extracardiac neural effects on cardiac activity of dogs and rats in the postnatal ontogenesis performed through vagotomy and administration of blocking agents in the intact and sympathectomized animals. Experiments on growing animals showed that the tonic effects of the vagus nerve on a pacemaker develop gradually as the sympathetic tone develops....
Alternative splicing (AS) is a major mechanism of increasing proteome diversity in complex organisms. Different AS transcript isoforms may be translated into peptide sequences of significantly different lengths and amino acid compositions. One important question, then, is how AS is constrained by protein structural requirements while peptide sequences may be significantly changed in AS events. ...
Sieve element (SE) protoplasts were liberated by exposing excised phloem strands of Vicia faba to cell wall-degrading enzyme mixtures. Two types of SE protoplasts were found: simple protoplasts with forisome inclusions and composite twin protoplasts-two protoplasts intermitted by a sieve plate-of which one protoplast often includes a forisome. Forisomes are giant protein inclusions of SEs in Fa...
Present study was designed to assess the effect of catalase on post-thaw semen quality parameters (SQPs), sperm kinematics, antioxidant and oxidative stress profiles cholesterol efflux in mithun (Bos frontalis). A total 25 ejaculates were selected based biophysical each sample split into four equal aliquots diluted (to get final concentration 60 million spermatozoa per mL) with TCG extender con...
