Ginger and the beetle: Evidence of primitive pollination system in a Himalayan endemic alpine ginger (Roscoea alpina, Zingiberaceae). [PDF]
The Himalayan endemic alpine genus Roscoea, like other members of ginger family, exhibits the combination of floral traits that would fit pollination by long distant foragers such as bees, birds or flies.

Herkogamy and its effects on mating patterns in Arabidopsis thaliana. [PDF]
The evolution of mating systems, which exhibit an extraordinary diversity in flowering plants, is of central interest in plant biology. Herkogamy, the spatial separation of sexual organs within flowers, is a widespread floral mechanism that is thought to

Selection favors loss of floral pigmentation in a highly selfing morning glory.
A common evolutionary trend in highly selfing plants is the evolution of the "selfing syndrome", in which traits associated with pollinator attraction are lost or greatly reduced.

Self‐concept in children with Down syndrome [PDF]
Self‐concept is a critical indicator of quality of life but few studies have examined this subject in children with Down syndrome (DS). In this study, we propose a novel methodology to assess the self‐concept of children with DS by analyzing their responses towards two dolls, one with a “typically developing” (TD) appearance and one with the phenotypic

Self‐correction prevents withdrawal syndrome [PDF]
The scientific research paper remains the primary mode for documenting scholarly achievement in a stable, citable manner, yet the toolkit that allows for changes and corrections to research papers limits the optimal dissemination of reliable research findings.

SECONDARY POLLEN PRESENTATION, PSYCHOPHILY AND ANEMOCHORY IN Lagascea mollis Cav. (ASTERACEAE)
Information on pollination ecology and seed dispersal aspects is essential to understand sexual reproduction in Lagascea mollis Cav. The study was aimed at providing details of pollen presentation system, pollination syndrome, pollinators and seed ...

Reproductive Evolution: Symptom of a Selfing Syndrome [PDF]
In the nematode Caenorhabditis elegans, a single gene (plg-1) encodes the dominant protein found in mating plugs - a means of inhibiting multiple matings. Naturally occurring loss of plg-1 function results in males that fail to deposit mating plugs - a manifestation of relaxed sexual selection since the evolution of self-fertilization in this species.

ABSTRACT Immune effector cell‐associated hemophagocytic lymphohistiocytosis‐like syndrome (IEC‐HS) is a life‐threatening hyperinflammatory toxicity distinct from cytokine release syndrome (CRS) and neurotoxicity following chimeric antigen receptor T‐cell (CAR‐T) therapy. In a single‐institution retrospective cohort of pediatric and young adult patients

ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We
