Investigation Of Touch-Sensitive Responses By Hyphae Of The Human Pathogenic Fungus Candida Albicans, N. A. R. Gow, T. H. S. Perera, J. Sherwood-Higham, G. W. Gooday, D. W. Gregory, D. Marshall

Scanning Microscopy

Candida albicans is a fungus that commonly infects the mucosal surface of humans. The hyphal growth form of this fungus may initiate the primary invasion of the host. Here we show that hyphae respond thigmotropically and morphologically to cues such as the presence of a surface, pores, grooves and ridges. Growth on some firm surfaces elicits a helical growth response. Hyphae follow grooves and ridges of inert substrates and penetrate pores of filtration membranes. Our in vitro experiments suggest that thigmotropism may enhance the ability of a hypha to invade epithelia of a host at sites of weakened integrity.

Biochemical And Histological Changes During Ovarian Development Of Cobia, Rachycentron Canadum, From The Northern Gulf Of Mexico, Patricia M. Biesiot, Robert E. Caylor, James S. Franks

Faculty Publications

Female cobia, Rachycentron canadum, were sampled on their spawning grounds in the Northern Gulf of Mexico to study changes in proximate analysis (protein, lipid, carbohydrate, and ash) of the ovaries during gonadal maturation. Four major stages of oocyte development were studied: stage 1, previtellogenesis; stage 2, vitellogenesis; stage 3, final maturation; and stage 4, postovulation. Cobia are multiple spawning fish; therefore, ovaries engaged in a sequential round of oogenesis were distinguished as stages 1' and 2'. Protein was the major constituent of cobia ovaries and its contribution of cobia ovaries and its contribution remained fairly constant (49-55% fo the …

The Effect Of Nitrogen Fertilization On The Phenology Of Roots In A Barrier Island Sand Dune Community, Everett P. Weber

Biological Sciences Theses & Dissertations

Little work has been done on the phenology of root growth and senescence largely due to methodological difficulties. The application of minirhizotron technology has enabled the tracking of individual roots through an entire growing season. As a result, direct measures of turnover, root growth, and an analysis of cohorts were made. Small plots on a 36 year old dune on Hog Island, a barrier island in the Virginia Coast Reserve Long Term Ecological Research Site, were fertilized with nitrogen. Minirhizotron tubes were installed in each fertilized and control plot. Each tube was sampled monthly for nine months, March through October …

Aboveground Biomass And Net Primary Production Along A Virginia Barrier Island Dune Chronosequence, John Joseph Dilustro

Biological Sciences Theses & Dissertations

Aboveground biomass was examined along a chronosequence of dune communities on Hog Island, a Virginia Coast Reserve LTER site. The dominant species were Ammophila breviligulata and Spartina patens. Aboveground biomass was harvested monthly from ten quadrats on dunes 6, 24, 36, and 120 years old. Sampling was conducted from April to November 1993. Biomass values were greater for younger dunes. Total aboveground biomass decreased with increasing site age and ranged from 152 g m^-2 on the 120 year old dune to 205 g m^-2 on the 6 year old dune in October 1993. Spartina patens biomass was …

Proceedings From The 31st Annual Italian And Specialty Cheese Seminar, Various Authors

Cheese Industry Conference

The impact of mixer temperature and mixer screw speeds on fat recovery, protein recovery, and yield of Mozzarella cheese was determined. In the first trial three different cheese temperatures were achieved: 130·F (54.C); 140•F (60.C); and 150.F (66·q. In the mixer temperature trial, a screw speed of 12 rpm (revolutions per minute) was used at all mixer temperatures. In the second trial, three different mixer screw speeds were used for stretching: 5 rpm, slow; 12 rpm, medium (ca. 50o/o of mixer full speed); 19 rpm, fast. Three vats of cheese were made per day. The two trials were conducted at …

Urinary Citrate, Bone Resorption And Intestinal Alkali Absorption In Stone Formers With Fasting Hypercalciuria, Piergiorgio Messa, Giuseppe Mioni, L. Paganin, A. Cruciatti, P. Lo Greco, D. Turrin

Scanning Microscopy

Reduced citrate in urine and increased fasting excretion of calcium are abnormalities frequently reported in stone forming (SF) patients. Increased dietary acid (or reduced alkali) introduction or absorption may be a potential cause of both these pathological findings. To test this hypothesis, we studied 64 SF patients {32 with fasting hypercalciuria (FH) and 32 without FH (NFH)}. After a basal evaluation for nephrolithiasis, while on a 500 mg calcium diet, they were evaluated for: (1) daily intestinal alkali absorption (IAA), by urinary electrolyte excretion; (2) basal concentrations of PTH, calcitonin (CT) and 1,25(OH)2-VitD; (3) oral calcium load for evaluation of …

What Science Can And Cannot Offer To A Religious Narrative, Ursula W. Goodenough

Biology Faculty Research

A molecular/cell biologist offers perspectives on the contributions that the scientific worldview might and might not make to religious though. It is argued that two essential features of institutionalized religions–their historical context and their supernatural orientation—are not addressed by the sciences, nor can the sciences contribute to the art and ritual that elicit states of faith and transcendence. The sciences have, however, important stories (myths) to offer, stories that have the potential to unify us, to tell us what is sacred, what has meaning, and how we might best proceed.

This paper, in slightly different form, was first presented before …

The Toxicity Of Cadmium To The Aquatic Amphibian, Xenopus Laevis, Sharon S. Millirons

Master's Theses

Cadmium toxicity is poorly understood but is a potentially serious environmental pollutant. This study was initiated to determine the effect of significant concentrations of cadmium on a readily available aquatic laboratory organism.

The lethal concentration (LC50) for 50 percent of I week old Xenopus laevis tadpoles was determined to be 0.1 ppm CdCI 2. For 5 week old animals, the average LC50 was determined to be 0.98 ppm. Thus, cadmium poses greater toxic threats to the early developmental stages. Moreover, these concentrations of cadmium exceed those commonly found in the nation's water supply. Histological examination suggested that the main site …

Circadian Clock Locus Frequency: Protein Encoded By A Single Open Reading Frame Defines Period Length And Temperature Compensation., Benjamin D. Aronson, Keith A. Johnson, Jay C. Dunlap

Dartmouth Scholarship

The frequency (frq) locus encodes a key component, a state variable, in a cellular oscillator generating circadian rhythmicity. Two transcripts have been mapped to this region, and data presented here are consistent with the existence of a third transcript. Analysis of cDNA clones and clock mutants from this region focuses attention on one transcript encoding a protein. FRQ, which is a central clock component: (i) mutations in all of the semidominant frq alleles are the result of single amino acid substitutions and map to the open reading frame (ORF) encoding FRQ; (ii) deletion of this ORF, or a frameshift mutation …

The Effect Of Insulin Mimetics On Enzymes Of Fatty Acid Biosynthesis, Eric A. Berg

Masters Theses

Fatty acid biosynthesis, an insulin regulated pathway, is the process of producing fatty acid chains from 2 and 3 carbon units. Two enzymes in this pathway that insulin affects are glucose-6-phosphate dehydrogenase (G6PDH) and fatty acid synthase (FAS). Sodium vanadate and sodium selenate have demonstrated insulin-like effects in several tissue and cell types. These mimetic effects include increasing glucose transport, regulating glycolytic enzymes, normalizing plasma glucose levels and activities of insulin regulated enzymes in diabetic rats. Our goal was to examine effects of sodium vanadate and sodium selenate on fatty acid biosynthesis in two insulin responsive systems: Isolated rat hepatocytes …

The Relationship Of Dietary And Lifestyle Factors To Bone Mineral Density Of Healthy Singaporean Chinese Women, Ampai Dana Aimsiri

Loma Linda University Electronic Theses, Dissertations & Projects

Few studies have examined the risk factors associated with reduced bone mass in Asians, but none specifically investigated Singaporean Chinese women. The subjects in this study were 16 premenopausal, 8 perimenopausal and 13 postmenopausal women who participated in a larger study which began in 1986. Bone density was measured in 1986 and 1992. Dietary and lifestyle data were collected for this study by personal interview. Association between dietary and lifestyle factors and bone density variables and change in bone density at the end of the 6 year period were assessed by univariate regression analyses.

Postmenopausal women had significantly lower baseline …

Effects Of Furosemide And Oleic Acid On Thyroxine Binding To Isolated Pairs Of Thyroxine Binding Serum Proteins, Deborah Hustead

Loma Linda University Electronic Theses, Dissertations & Projects

Dosage dependent binding inhibition and redistribution of thyroxine (T₄) between three pairs of thyroxine binding serum proteins, TBG-TTR, TBG-albumin and TTR-albumin, by furosemide (0.0 to 1.0 mol/L) and oleic acid (0.0 to 0.10 mol/L) were studied using equilibrium dialysis with purified binding proteins at concentrations 1/200 of levels in normal human sera, separated across the dialysis membrane and competing for T₄.

Furosemide (1.0 mol/L) reduced TBG bound T₄ in both the TBG-TTR system and TBG-albumin system (>90% decrease) and inhibited T₄ binding to TTR in the TTR-albumin system (68% decrease) and to albumin …

Living Mulches Suppress Aphids In Broccoli, Michael J. Costello, Miguel A. Altieri

Horticulture and Crop Science

A living mulch combines an annual crop with a cover crop to provide pest control and soil protection. Results of a study in the Salinas Valley show cabbage aphid infestation can be lowered on broccoli grown in living mulches compared to clean cultivation, possible because light reflectance patterns are less attractive to incoming aphids. Early and intense mowing of the cover crop and adequate irrigation maintained broccoli yield in living mulches relative to clean cultivation. Lack of specialized equipment is the main limitation to the commercial application of living mulches at this time.

Effect Of Baculovirus Penaei On Growth And Survival Of Experimentally Infected Postlarvae Of The Pacific White Shrimp, Penaeus Vannamei, Kenneth C. Stuck, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In a series of experiments conducted to investigate age and size-dependent effects of the baculovirus BP on postlarvae of the Pacific white shrimp, Penaeus vannamei, six groups of specific pathogen-free shrimp of different ages (mysis 2–3 through PL 25) were exposed to the virus and cultured for 15 to 21 days. All BP-exposed groups of early postlarvae (PL 9 or younger) became heavily infected within 2–5 days of initial exposure to the virus, and some of those groups experienced high mortalities compared to the noninfected controls. Postlarvae that survived the infection had highly variable and significantly reduced growth, as …
