Abstract

Cat domestication likely initiated as a symbiotic relationship between wildcats (Felis silvestris subspecies) and the peoples of developing agrarian societies in the Fertile Crescent. As humans transitioned from hunter-gatherers to farmers ~12,000 years ago, bold wildcats likely capitalized on increased prey density (i.e., rodents). Humans benefited from the cats' predation on these vermin. To refine the site(s) of cat domestication, over 1000 random-bred cats of primarily Eurasian descent were genotyped for single-nucleotide variants and short tandem repeats. The overall cat population structure suggested a single worldwide population with significant isolation by the distance of peripheral subpopulations. The cat population heterozygosity decreased as genetic distance from the proposed cat progenitor's (F.s. lybica) natural habitat increased. Domestic cat origins are focused in the eastern Mediterranean Basin, spreading to nearby islands, and southernly via the Levantine coast into the Nile Valley. Cat population diversity supports the migration patterns of humans and other symbiotic species.

Abstract

A study of the parasite fauna of feral cats in Dubai revealed the presence of two Joyeuxiella species, J. pasqualei (Diamare, 1893) and J. fuhrmanni (Baer, 1924). While the wide distribution of J. pasqualei includes countries of the Middle East, Africa, Asia and Europe, J. fuhrmanni was previously reported from felid hosts from southern Africa and has not been found in other cat parasite surveys in the Middle East, except from Dubai. The availability of historical references, however, raised doubts about the correctness of the allocation of the small Joyeuxiella sp. from Dubai cats to J. fuhrmanni and for this reason, a reexamination of stored material in the parasite collection of the Central Veterinary Research Laboratory in Dubai was carried out. A total of 40 specimens of the small Joyeuxiella sp. with a strobila length between 30 and 60 mm and consisting of 52 to 85 segments obtained from domestic cats and formerly allocated to J. fuhrmanni were studied. In complete specimens, 10 – 13 rows of rostellar hooks were counted. Mature segments were wider than long, round testes were concentrated posterior to coiled vasa deferentia and did not reach the anterior rim of the proglottids. Narrow cirri reached up to 520 μm in length. Gravid segments were longer than wide and egg capsules were restricted to the space between longitudinal excretory vessels. The examination revealed that the morphology of these cestodes matched the main characteristics of J. fuhrmanni. However, the little known cestode, J. gervaisi (Setti, 1895), that had been described from Genetta abyssinica imported from Eritrea 29 years earlier and was declared a species inquirenda met the same main morphological criteria. In this paper, the status of J. gervaisi as a valid species was resurrected and J. fuhrmanni was declared a junior synonym.

Abstract

We present results from the SPring-8 Angstrom Compact free electron LAser (SACLA) XFEL facility, using a high intensity ($\sim\!10^{20}\,$W/cm$^2$) X-ray pump X-ray probe scheme to observe changes in the ionic structure of silicon induced by X-ray heating of the electrons. By avoiding Laue spots in the scattering signal from a single crystalline sample, we observe a rapid rise in diffuse scattering, which we attribute to a loss of lattice order and a transition to a liquid state within 100 fs of irradiation, a timescale which agrees well with first principles simulations, but is faster than that predicted by purely inertial behavior. This method is capable of observing liquid scattering without masking or filtering of signal from the ambient solid, allowing the liquid structure to be measured throughout and beyond the phase change., Comment: 6 pages, 5 figures.

Abstract

Background/objectivesTo analyze the refractive predictability and outcomes of cataract surgery in the very elderly (≥85 years old).Subjects/methodsA retrospective case-series performed at the Shiley Eye Institute, University of California San Diego, USA. Electronically pulled data of 2444 surgeries revealed 147 surgeries on 133 very elderly patients. Chart review was conducted for all very elderly and corresponding control patients (75-84 years old). The first operated eyes of patients with final best-corrected visual acuity ≥20/40, axial length (AL) 22-26 mm, and implanted SN60WF IOL were included. Patients with ocular comorbidities and/or intra- or post-operative complications were excluded. Prediction errors of refractive outcome and percentage of eyes within ±0.50D and ±1.00D were compared between the groups for the Holladay 1 and Barrett Universal II (Barrett) formulas. Logistic regression analysis for achievement of ±1.00D was conducted.ResultsFinal analysis included 90 eyes (n = 44, very elderly, n = 46, control patients). Median absolute refractive error (MedAE) with Holladay 1, but not Barrett formula, was significantly higher in the older group (p = 0.02 and p = 0.07, respectively). The MedAE in the older group was lower using the Barrett compared to Holladay 1 (p = 0.02). Fewer older patients than younger patients achieved refraction within ±0.50D and ±1.00D from goal, using the Holladay 1 (p = 0.049 and p = 0.002 respectively). Logistic regression analysis supported the relationship between Holladay 1 predictive refractive error of >1.00D and patient's age (p = 0.046).ConclusionsVery elderly patients undergoing cataract surgery may be prone to reduced refractive precision, particularly with utilization of the Holladay 1 formula.
