ABSTRACT
Monitoring of biodiversity is a critical component of effective conservation, enabling a greater understanding of the distribution and abundance of species and changes in faunal assemblages, while allowing the evaluation of land management actions. Here we report on the first systematic fauna surveys conducted on Edgbaston Reserve between 2018 and 2020. Data were analysed to understand mammal, reptile and amphibian species composition, richness, and abundance in relation to six habitat types (Mitchell Grass, Spinifex, Springs, Ironbark, Gidgee and Escarpment) and over five different survey periods (spanning October 2018 to October 2020). This study reports on a species assemblage typical of Northern Australia savanna environments, with some distinction between key habitats, namely grassland and woodlands. We recorded a total of 13 native and one introduced amphibian species, 12 native and three introduced mammal species, and 54 reptile species comprising 1384 records across 24 sites. Twelve species were only recorded once in all five surveys. The ten most frequently recorded species were Heteronotia binoei, Gehyra versicolor, Litoria caerulea, Ctenotus capricorni, Planigale tenuirostris, Oedura cincta, Gehyra catenata, Strophurus williamsi, Menetia greyii and Ctenotus pantherinus. In general, the faunal communities across the habitat types had a high degree of overlap due to the interconnectedness of the vegetation across the reserve. This short study demonstrated the significance of this small conservation reserve for the protection of a high diversity of terrestrial vertebrate fauna due to its location in a biogeographic transition zone from the wetter east coast of Australia, into the arid interior. These data are an important foundation for continued monitoring that can be used to investigate responses to management and environmental perturbation.

Published: February 2025

The surge in the prevalence of neurodevelopmental conditions including Autism Spectrum Disorder; a Disarray typically defined by a wide variety of conditions marked by difficulties in social skills, repetitive behaviors, disorganized speech, and challenges with nonverbal communication has increased the quest to elucidate its underlying mechanisms and create effective treatments by maximizing different animal models.
In recent decades, animal studies on autism spectrum disorder maximizing different animal models have increased. Despite the number of animal models in these findings, lasting alleviating measures have not been actualized, the known animal models are also associated with several limitations such as being too expensive, too unwieldy to handle, and characterized by a prolonged reproductive cycle, while in some areas of the world, they are becoming harder to acquire. In this regard, research is now focusing on the need to search for animal models unaffected by the stated limitations associated with the well-known animal models. Drosophila Melanogaster (fruit fly) as a model organism in neurodegenerative, and neurodevelopmental diseases have been used by a few studies. This review examines the significance of fruit flies as a more effective model for studying ASD.
Effect of Elicitation on Growth, Respiration, and Nutrient Uptake of Root and Cell Suspension Cultures of Hyoscyamusmuticus
Authors: Carvalho Edgard B. , Curtis Wayne R. 
Published: July 2002

AbstractThe elicitation of Hyoscyamus muticus root and cell suspension cultures by fungal elicitor from Rhizoctonia solani causes dramatic changes in respiration, nutrient yields, and growth. Cells and mature root tissues have similar specific oxygen uptake rates (SOUR) before and after the onset of the elicitation process. Cell suspension SOUR were 11 and 18 μmol O2/g FW·h for non‐elicited control and elicited cultures, respectively. Mature root SOUR were 11 and 24 μmol O2/g FW·h for control and elicited tissue, respectively. Tissue growth is significantly reduced upon the addition of elicitor to these cultures. Inorganic yield remains fairly constant, whereas yield on sugar is reduced from 0.532 to 0.352 g dry biomass per g sugar for roots and 0.614 to 0.440 g dry biomass per g sugar for cells. This reduction in yield results from increased energy requirements for the defense response. Growth reduction is reflected in a reduction in root meristem (tip) SOUR, which decreased from 189 to 70 μmol O2/g FW·h upon elicitation. Therefore, despite the increase in total respiration, the maximum local oxygen fluxes are reduced as a result of the reduction in metabolic activity at the meristem. This distribution of oxygen uptake throughout the mature tissue could reduce mass transfer requirements during elicited production. However, this was not found to be the case for sesquiterpene elicitation, where production of lubimin and solavetivone were found to increase linearly up to oxygen partial pressures of 40% O2 in air. SOUR is shown to similarly increase in both bubble column and tubular reactors despite severe mass transfer limitations, suggesting the possibility of metabolically induced increases in tissue convective transport during elicitation.
Human cytokine responses induced by Gram-positive cell walls of normal intestinal microbiota

Published: July 2002

SUMMARY
The normal microbiota plays an important role in the health of the host, but little is known of how the human immune system recognizes and responds to Gram-positive indigenous bacteria. We have investigated cytokine responses of peripheral blood mononuclear cells (PBMC) to Gram-positive cell walls (CW) derived from four common intestinal indigenous bacteria, Eubacterium aerofaciens (Eu.a.), Eubacterium limosum (Eu.l.), Lactobacillus casei (L.c.), and Lactobacillus fermentum (L.f.). Our results indicate that Gram-positive CW of the normal intestinal microbiota can induce cytokine responses of the human PBMC. The profile, level and kinetics of these responses are similar to those induced by lipopolysaccharide (LPS) or CW derived from a pathogen, Streptococcus pyogenes (S.p.). Bacterial CW are capable of inducing production of a proinflammatory cytokine, tumour necrosis factor-alpha (TNF-α), and an anti-inflammatory cytokine, IL-10, but not that of IL-4 or interferon-gamma (IFN-γ). Monocytes are the main cell population in PBMC to produce TNF-α and IL-10. Induction of cytokine secretion is serum-dependent; both CD14-dependent and -independent pathways are involved. These findings suggest that the human cytokine responses induced by Gram-positive CW of the normal intestinal microbiota are similar to those induced by LPS or Gram-positive CW of the pathogens.

SUMMARYTo characterize the T cell response to Porphyromonas gingivalis, we examined the expression of costimulatory molecules on T cells derived from adult periodontitis patients with high serum antibody titre to P. gingivalis. The expression of CD28, CTLA-4, CD40 ligand (CD40L) on CD4+ T cells was analysed by flow cytometry. IL-10 and transforming growth factor-beta (TGF-β) mRNA expression were determined by reverse transcription-polymerase chain reaction (RT-PCR) and subsequent image analysis. Peripheral blood mononuclear cells (PBMC) derived from periodontitis patients showed higher proliferative responses to P. gingivalis outer membrane (OM) than those from healthy controls (P &lt; 0.05). The percentage of CTLA-4+ cells within CD4+ T cells of patients was significantly higher than that of healthy controls after P. gingivalis OM stimulation (33.0% versus 11.9%, P &lt; 0.01). There was no significant difference in the percentages of CD28+ cells and CD40L+ cells, and the percentage of CD40L+ cells was low in both groups even after stimulation. Stimulation of PBMC with P. gingivalis OM induced significantly higher IL-10 mRNA expression in periodontitis patients than in healthy controls (P &lt; 0.05). The level of TGF-β mRNA expression of patients tended to be higher than that of healthy controls, but there was no significant difference. To elucidate the functional role of CTLA-4, we further investigated the secondary proliferative response to P. gingivalis OM. Interestingly, P. gingivalis OM stimulation did not enhance antigen-specific secondary response. Anti-CTLA-4 MoAb had no effect on proliferation in the presence of P. gingivalis OM. CTLA-4Ig suppressed the proliferative response significantly (P &lt; 0.01). These results suggest that T cell responses to P. gingivalis OM may be regulated by CTLA-4 that is expressed at the late phase of T cell activation, and, in part, immunosuppressive cytokines. Taken together, CTLA-4 may play a crucial role in the pathogenesis of chronic inflammatory periodontal disease.
An axially vascularized meatal‐based flap for the repair of hypospadias

Published: July 2002

Objectives To report the initial experience of hypospadias repair using an axially vascularized meatal‐based skin flap.Patients and methodsTwenty‐six children aged 2–5.5 years with subcoronal hypospadias underwent the procedure; three were circumcised and three had recurrent hypospadias. The neourethra was constructed using a meatal‐based flap extending obliquely from the hypospadiac orifice towards the prepuce or its remnants. The flap was supplied axially by the ventrolateral branch of the superficial external pudendal artery. The vascular pedicle was dissected and mobilized to allow tensionless reflection of the flap ventrally to be sutured to the urethral plate.ResultsFunctional and cosmetic success was achieved in 25 of the patients (96%). Haematoma and disruption of the flap occurred in one patient, who underwent re‐operation, and slight and insignificant meatal retraction occurred in another child.ConclusionsThe procedure confirmed the technical feasibility of creating an axially vascularized meatal‐based flap. The oblique orientation of the flap permits it to be obtained from well‐developed skin. Continuity of the oblique flap with the urethral plate reduces the total length of suture lines and minimizes the possibility of fistula formation.
Prenatal ultrasound findings in a fetus with paternal uniparental disomy 14q12‐qter

Published: July 2002

AbstractWe present the prenatal ultrasound findings in a case of postnatally identified paternal uniparental isodisomy 14q12‐qter. Increased nuchal translucency and a large omphalocele were identified at 14 weeks' gestation. Karyotyping revealed a normal male, 46,XY. As gestation advanced, polyhydramnios developed, skeletal abnormalities involving the long bones and chest became evident, hand contractures developed, and the presumed large omphalocele was in part found to be a large ventral hernia, as echogenic adipose tissue could be seen in the abdominal wall near to the cord insertion. Prenatal findings were confirmed after delivery and central nervous system imaging revealed lissencephaly. The combination of an abdominal wall defect with either increased nuchal translucency or skeletal abnormalities should prompt an investigation for uniparental disomy 14 even if the karyotype is normal.

A magnetic, neutron diffraction, and Mössbauer spectral study of the Ce2Fe17−xAlx solid solutions

Published: July 2002

The magnetic properties of a series of Ce2Fe17−xAlx solid solutions with x equal to 0.00, 0.88, 2.06, 2.81, 3.98, 5.15, 6.08, 7.21, 8.20, 9.08, 9.84, and 10.62 have been studied by magnetic measurements, neutron diffraction, and Mössbauer spectroscopy. The compounds crystallize in the rhombohedral Th2Zn17-type structure. Magnetization studies indicate that the Curie temperature increases uniformly from 238 K for Ce2Fe17 to 384 K for Ce2Fe14Al3 and then decreases at higher aluminum content. Powder neutron diffraction results, obtained at 295 K, indicate that aluminum avoids the 9d site for all x values and preferentially occupies the 18h site at low aluminum content. Aluminum shows a marked preference for the 6c site for x≳6. The room-temperature iron magnetic moments increase from x=0 to 2 and then decrease for x≳2. The Mössbauer spectra have been fit with a binomial distribution of the near-neighbor environments in terms of a maximum hyperfine field, Hmax, for an iron with zero aluminum near neighbors, and a decremental field, ΔH, per aluminum near neighbor. The compositional dependence of the decremental field indicates the influence of aluminum on the long-range magnetic ordering in the compound.
The compositional dependence of the weighted average maximum hyperfine fields and the weighted average isomer shifts in Ce2Fe17−xAlx may be understood in terms of a mixing of the 3d conduction band electrons with the 3p valence band electrons of aluminum, a mixing which is more extensive than that associated with silicon in the Ce2Fe17−xSix solid solutions. We conclude that this mixing has a larger influence on the magnetic properties of these solid solutions than does the presence of a short iron–iron bond or the expansion or contraction of the lattice parameters and unit cell volume.
Confined geometry effects on reorientational dynamics of molecular liquids in porous silica glasses
Authors: Liu G. , Li Y. , Jonas J. 
Published: July 2002

This work investigates the relative role of the pure geometrical confinement and the strength of the surface effect on the dynamics of liquids in porous silica glasses prepared by the sol-gel process. The deuteron NMR spin-lattice relaxation times T1 of several molecular liquids in porous silica glasses are reported as function of pore size in the range from 18 to 143 Å over the temperature range from 260 to 310 K. Molecular liquids studied include strongly interacting polar liquids such as pyridine-d5, aniline-d5, and nitrobenzene-d5, whereas the saturated cyclic hydrocarbon liquids of cyclohexane-d12 and cis-decalin-d18 represent the weakly interacting liquids. In a first approximation, toluene-d1 and dioxane-d18 are chosen as examples of liquids with intermediate interactions with the silica surface. The experimental relaxation data are analyzed by using the two-state, fast-exchange model which is found to be valid for the strongly interacting liquids and liquids with intermediate interactions. In terms of this model, the viscosity of the surface layer for pyridine-d5 is about 30 times higher than that for bulk liquid pyridine.
The importance of the two-dimensional approach to describe motional dynamics of liquids confined to pores smaller than 30 Å is illustrated in the case of weakly interacting liquid of cyclohexane-d12. Additional information on the relative role of surface interactions and the pure topological effects on the dynamics of liquids in confined geometries was obtained by using surface-modified glasses in which the surface hydroxyl groups were replaced by OSi(CH3)2OC2H5 groups. Indeed, the effects of surface modifications on the 2H T−11 are most pronounced for strongly interacting liquids whereas they are absent for cyclohexane. In agreement with the concept of two-dimensional behavior of liquids in small pores, one finds that the low-frequency relaxation times, namely, the spin–spin relaxation time T2, and the spin-lattice relaxation time in the rotating coordinate frame, T1ρ, remain unchanged by surface modification. In fact, this is a consequence of logarithmic enhancement of the spectral density at low frequencies so that the effect of pure geometrical confinement on the T−12 and T−11ρ relaxation rates is much larger than any relaxation rate changes arising from surface modification. Several selected NMR T1 experiments on pyridine-d5 confined to anopore and zeolites are also presented.
State-to-state rotational energy-transfer measurements in the v2=1 state of ammonia by infrared–infrared double resonance
Authors: Abel Bernd , Coy Stephen L. , Klaassen Jody J. , Steinfeld Jeffrey I. 
Published: July 2002

An infrared double-resonance laser spectroscopic technique is used to study state-resolved rotational (R–R, R–T) energy transfer in ammonia (14NH3) (self-collisions and between ammonia and foreign gases). NH3 molecules are prepared in selected rovibrational states of the v2=1 level using coincidences between CO2 -laser lines and ν2 fundamental transitions. Measurements of both the total rate of depopulation by collisions, and the rates of transfer into specific final rovibrational states (v,J,K) have been carried out using time-resolved tunable diode laser absorption spectroscopy. For NH3–NH3 collisions, measurements of total depopulation rates of selected JK states in v2=1 and ground-state recovery rates are found to be three and eight times larger, respectively, than the Lennard-Jones collision rate, in accord with theoretical expectations for polar molecules.
A kinetic master-equation analysis of time-resolved level populations yields state-to-state rate constants and propensity rules for NH3–NH3 and NH3–Ar collisions. Individual rotational energy-transfer rates in v2=1 are slower than in the vibrational ground state, but still comparable to the Lennard-Jones collision frequency. Our experiments show that rotational energy transfer in v2=1 is not governed by simple ‘‘dipolelike’’ selection rules. They show fast rotational energy transfer, which can be related to long-range interaction potentials, but at the same time considerable amounts of ΔJ=2 and 3, ΔK=0, and ΔJ=1–4, ΔK=3, transitions, which may be attributed to higher-order terms in the multipole expansion of the intermolecular potential. No pronounced symmetry-state correlation and no preferred pathways were found except the preference for relaxation within a K stack and the expected separate relaxation of different nuclear-spin species, which can be labeled by their K-quantum number. Rates of collision-induced symmetry change (a↔s) in v2=1 are on the order of kas=4 μs−1 torr−1, smaller than kas in the ground state, but over an order of magnitude larger than that recently reported in the literature. Depopulation rates for other collision partners (Ar, H2, N2, and He) can be understood in terms of the intermolecular potentials. Comparisons are made between the relaxation rates measured in this work and infrared pressure-broadening coefficients reported in the literature.
