Diagnosis And Distribution Of Florida Sand Darter, Ammocrypta Bifascia (Teleostei; Percidae), In The Flint River, Georgia, Camm C. Swift, Gregory R. Moyer, Christine E. Fallon, Brett Albanese
Southeastern Fishes Council Proceedings
Abstract: In 2013, we observed the presence of an undocumented Ammocrypta species in the lower Flint River, Georgia. The occurrence represents the first record of the genus in Georgia. Subsequent surveys at 24 sites, using seining or snorkeling, documented additional specimens from mainstem sites (n = 3) between Albany and Bainbridge and from Ichawaynochaway Creek (n = 5 sites), a large tributary to the Flint River. We used morphological and genetic data to identify specimens to species. Morphological examination included 23 morphometric and 8 meristic characters from fifteen specimens that were compared to specimens from Williams (1975). For genetic analyses, …
The Deleterious F109s Mutation Disrupts Binding Of Sex-Determining Region Y With Dna, Mohammed Baqur S. Al-Shuhaib Mbsa
The Deleterious F109s Mutation Disrupts Binding Of Sex-Determining Region Y With Dna, Mohammed Baqur S. Al-Shuhaib Mbsa

Sex-determining region Y (SRY) protein is the master switch in the initiation of male sex differentiation. Mutation in SRY gene results in ambiguous genitalia and abnormalities in reproductive organs. Its function is mainly controlled by its high mobility group (HMG) box. Damage to the HMG box may cause dysfunction of the SRY protein, which may, in turn, lead to sex reversal. This study was conducted to prioritize the deleterious effects of the non-synonymous single nucleotide polymorphisms (nsSNPs) on SRY protein. A series of computational tools were applied to predict nsSNPs with the most harmful effects on protein structure, function, and …

The normal flora community plays a significant role in both healthy and patient individual’s bodies. It has improved its ability to change from beneficial to opportunistic organisms causing crucial infections in immunocompromised patients. This study was conducted to identify the community of yeast species, and to investigate potential virulence factors. Saliva samples were collected from healthy individuals, yeast species were isolated and identified using both traditional and advance molecular genetics technique. The results revealed that Candida albicans was the dominant isolate, while Meyerozyma caribbica was the least. The phylogenetic tree was constructed for 13 species using the Neighbour-Joining method, which …
Molecular Identification, Antioxidant Efficacy Of Phenolic Compounds, And Antimicrobial Activity Of Beta-Carotene Isolated From Fruiting Bodies Of Suillus Sp, Shimal Yonuis Abdulhadi, Raghad Nawaf Gergees, Ghazwan Qasim Hasan
Molecular Identification, Antioxidant Efficacy Of Phenolic Compounds, And Antimicrobial Activity Of Beta-Carotene Isolated From Fruiting Bodies Of Suillus Sp, Shimal Yonuis Abdulhadi, Raghad Nawaf Gergees, Ghazwan Qasim Hasan

Suillus species, in general, are edible mushrooms, and environmentally important that are associated mostly with pine trees in the tropics regions. These fungi considered a remarkable source of phenolic compounds that play a crucial role as antioxidants which may reduce the risk of most human chronic diseases such as cancer, diabetes, asthma, atherosclerosis, Alzheimer, and others. On the other hand, carotenoids (β carotene) are the most popular natural pigments which play an important role to protect the plants from photo-oxidative reactions. In human, these compounds prevent oxidative stress and expects to have antimicrobial activity. Here, the phenolic compounds were …

Although molecular approaches can identify members of microbial communities in the environment, genomic information does not necessarily correlate with environmental phenotype. Understanding functional roles can be done by cultivating representative species, yet the culturablility of bacteria from caves remains low, at 0.02%, limiting our understanding of microbial community interactions and processes. We have investigated several factors influencing culturability of bacteria from a single sample location in Maxwelton Sink Cave, WV, USA. Extended incubation of inoculated plates showed a significant increase in colony counts from two to four weeks, indicating that extended incubations increase culturability. There were no significant differences in …

Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell
Southeastern Fishes Council Proceedings
The topminnow species Fundulus notatus and F. olivaceus have broadly overlapping geographic distributions that extend throughout much of the central and southern United States. In the northern portion of their respective ranges, in Missouri, the regional distributions of the two species coincide largely with recognized ecoregions. In the unglaciated southern half of Missouri, F. olivaceus is distributed throughout Ozark upland habitats while F. notatus is abundant in marginal large river and prairie habitats along the Ozark borders. An exception to this partitioning is the historical report of abundant F. notatus in the Bourbeuse and upper Meramec River drainages within the …

Arthritis is a chronic inflammatory disease that causes severe joint pain. Interleukin 17F (IL17F) is considered as a candidate gene functionally; it mediates pro-inflammatory responses, depending on the type and site of inflammation. The present study examined the polymorphism of IL17F (rs763780 and rs2397084) among the families affected by arthritis. Demographic data and blood samples were collected from the families with at least one affected offspring with arthritis. Analysis of the IL17F gene polymorphism was performed by the digestion of DNA with NlaIII and AvaII. The results showed that IL17F rs763780 (AA, AG and GG genotypes) and rs2397084 (AA, AG …

Poisonous Plant Research (PPR)
Locoweeds are the most widespread poisonous plant problem in the world and have been reported in the Western United States since the 1800s, causing tremendous losses in livestock. Consumption of locoweeds by grazing animals stimulates the neurological disease, locoism, characterized by weight loss, ataxia, and lack of muscular coordination. The name locoweed is used for Astragalus and Oxytropis species known to contain swainsonine, the toxic principle produced by the plant endophytic fungus Undifilum. Astragalus includes 2,500-3,000 species and many varieties that have almost identical morphological characteristics that overlap among species, leading to improper identification. Therefore, the aim of this study …

A Nonhomologous End-Joining Mutant For Neurospora Sitophila Research, Nicholas A. Rhoades, Elise K. Webber, Thomas M. Hammond
Fungal Genetics Reports
Disruption of the nonhomologous end-joining (NHEJ) pathway has been shown to increase the efficiency of transgene integration into targeted genomic locations of Neurospora crassa and other fungi. Here, we report that a similar phenomenon occurs in a second Neurospora species: N. sitophila. Specifically, we show that deletion of N. sitophila mus-51 increases the efficiency of targeted-transgene integration, presumably by disrupting NHEJ. Researchers interested in obtaining the N. sitophila mus-51∆ strains described in this study can obtain them from the Fungal Genetics Stock Center (FGSC, Kansas State University, Manhattan, KS).
Gene Expression Pattern Analysis Of Anterior Hox Genes During Zebrafish (Danio Rerio) Embryonic Development Reveals Divergent Expression Patterns From Other Teleosts, Adam Davis
Georgia Journal of Science
The regional identity of organs and organ systems along the anterior-posterior axis during embryonic development is patterned, in part, by Hox genes, which encode transcription factor proteins that activate or repress the expression of downstream target genes. Divergent nested Hox gene expression patterns may have had a role in facilitating morphological divergence of structures, such as the pharyngeal jaw apparatus, among evolutionarily divergent teleost fishes. Recent studies from several evolutionarily divergent teleosts, such as the Japanese Medaka (Oryzias latipes) and the Nile Tilapia (Oreochromis niloticus), have shown the presence of divergent expression patterns of several Hox …
