Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Genetically engineered human cortical spheroid models of tuberous sclerosis. [PDF]

open access: yes, 2018
Tuberous sclerosis complex (TSC) is a multisystem developmental disorder caused by mutations in the TSC1 or TSC2 genes, whose protein products are negative regulators of mechanistic target of rapamycin complex 1 signaling. Hallmark pathologies of TSC are

Potato tuber lenticels: development and structure

open access: yesAnnals of Applied Biology, 1975
SUMMARYStomata on growing potato tubers are changed to lenticels by about the third internode from the apical bud (A‐3). In wet soil lenticels proliferate, while in dry soil the filling cells become suberized by about the fifth internode (A‐5).Lenticels did not proliferate in the field after mid‐August, and laboratory experiments on freshly harvested ...

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

open access: yesThe Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.

The Effects of Water Deficiency on Plant and Tuber Growth of Kohlrabi (Brassica oleracea L. var gongylodes)

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2020
Kohlrabi, which has increased production in our country in recent years, is a vegetable with high water consumption. The aim of this study was to determine the effects of different irrigation levels on plant and tuber growth and determine the appropriate

Taro leaf and stylo forage as protein sources for pigs in Laos [PDF]

open access: yes, 2012
Existing forage plants may have applications as alternative protein resources for pigs in smallholder farming systems. This thesis examined the effect of harvesting/defoliation interval on the yield and chemical composition of taro leaves and stylo ...

The detection of airborne transmission of tuberculosis from HIV-infected patients, using an in vivo air sampling model [PDF]

open access: yes, 2007
Background. Nosocomial transmission of tuberculosis remains an important public health problem. We created an in vivo air sampling model to study airborne transmission of tuberculosis from patients coinfected with human immunodeficiency virus (HIV) and ...

The 3‐Hit Metabolic Signaling Model for Autism Spectrum Disorder: A Summary

open access: yesAutism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a highly heritable yet environmentally sensitive neurodevelopmental condition whose biological heterogeneity has resisted a unifying causal explanation for over 100 years. The 3‐hit metabolic signaling model proposes that ASD arises from abnormal persistence of an evolutionarily conserved stress‐response ...

Dynamic Field Assessment of Canopy Development and Periderm Maturation in Potato (Solanum tuberosum L.)

open access: yesPlants
Background: Periderm development in potato (Solanum tuberosum L.) is critical for protecting tubers from biotic and abiotic stress, yet the relationship between periderm maturation, canopy development, and tuber growth during the active growing season ...

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated
