Integrating Immune Checkpoint Inhibitors With Total Neoadjuvant Therapy in Proficient Mismatch Repair Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
The key to unlocking ICI benefit in pMMR/MSS LARC is to convert “cold” tumors into “hot” ones through lymphocyte‐sparing SCRT and judicious chemotherapy, creating a milieu in which ICIs can act effectively. ABSTRACT The management of locally advanced rectal cancer (LARC) has evolved with the adoption of total neoadjuvant therapy (TNT), integrated ...

Salt intake and regulation in two passerine nectar drinkers: white-bellied sunbirds and New Holland honeyeaters [PDF]

, 2012
Avian nectarivores face the dilemma of having to conserve salts while consuming large volumes of a dilute, electrolyte-deficient diet. This study evaluates the responses to salt solutions and the regulation of salt intake in white-bellied sunbirds ...

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

American Journal of Botany, EarlyView.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

The potential for flower nectar to allow mosquito to mosquito transmission of Francisella tularensis. [PDF]

PLoS ONE, 2017
Francisella tularensis is disseminated in nature by biting arthropods such as mosquitoes. The relationship between mosquitoes and F. tularensis in nature is highly ambiguous, due in part to the fact that mosquitoes have caused significant tularemia ...

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

The Impact of Yeast Presence in Nectar on Bumble Bee Behavior and Fitness

Bulletin of the Ecological Society of America, 2019
The presence of yeasts in pollen and floral nectar is rather the norm than the exception. Due to the metabolic activities of yeasts, sugar and amino acid composition of nectar often drastically change and may negatively impact the nutritional value of ...

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Effects on herbicides on hedgerow biodiversity [PDF]

, 2008
Low dosages of herbicides may reduce the number of flowers on non-target plants. Effect of herbicides on flowering and on pollen and nectar production are relevant end-points for effect assessment on non-target species.

Nectar defense and hydrogen peroxide in floral nectar of Cucurbita pepo

Acta Agrobotanica, 2015
This study was carried out to investigate some similarities between the nectaries of <em>Nicotiana</em> sp. and <em>Cucurbita</em> pepo, such as starch accumulation in the nectary parenchyma, changes in nectary color during maturation, and the production of a large quantity of sucrose-dominant nectar.

Probabilistic assessment of nectar requirements for nectar-foraging honey bees [PDF]

Apidologie, 2019
AbstractRecent concerns regarding potential effects of pesticides on pollinators have prompted regulatory agencies to estimate dietary ingestion rates for honey bees (Apis mellifera). The task is difficult because of the complex caste and food storage systems in honey bee colonies.
