Anatomy of the reproductive system of a population of Amerotyphlops brongersmianus from southeastern Brazil (Serpentes: Scolecophidia)

The Anatomical Record, 2020
Amerotyphlops brongersmianus (Vanzolini, 1976) is distributed in Brazil from the Atlantic Rainforest to the Cerrado biome. Only few studies have focused on the gross anatomy, reproductive organs, and histological data of typhlopids.

Linking wood anatomy and xylogenesis allows pinpointing of climate and drought influences on growth of coexisting conifers in continental Mediterranean climate.

Tree Physiology, 2016
Forecasted warmer and drier conditions will probably lead to reduced growth rates and decreased carbon fixation in long-term woody pools in drought-prone areas.

Fire damage to cambium affects localized xylem anatomy and hydraulics: the case of Nothofagus pumilio in Patagonia.

American-Eurasian journal of botany, 2019
PREMISE Fire scars on trees are created by excessive heat from a fire that kills the vascular cambium. Although, fires are one of the most important forest disturbances in Patagonia, the effects of fire on tree physiology and wood anatomy are still ...

The links between leaf hydraulic vulnerability to drought and key aspects of leaf venation and xylem anatomy among 26 Australian woody angiosperms from contrasting climates

Annals of Botany, 2018
Background and Aims The structural properties of leaf venation and xylem anatomy strongly influence leaf hydraulics, including the ability of leaves to maintain hydraulic function during drought.

The states of water in Norway spruce (Picea abies (L.) Karst.) studied by low-field nuclear magnetic resonance (LFNMR) relaxometry: assignment of free-water populations based on quantitative wood anatomy

, 2016
Low-field nuclear magnetic resonance (LFNMR) relaxometry was applied to determine the spin-spin relaxation time (T2) of water-saturated Norway spruce (Picea abies (L.) Karst.) specimens cut from mature sapwood (sW) and mature and juvenile heartwood (hW),

Relevance of wood anatomy and size of Amazonian trees in the determination and allometry of sapwood area

Acta Amazonica, 2019
Hydrological processes in forest stands are mainly influenced by tree species composition and morpho-physiological characteristics. Few studies on anatomical patterns that govern plant hydraulics were conducted in tropical forest ecosystems.

Anatomy of Charcoal and Carbonization Effect under Eucalyptus Fibers’ Dimensions

, 2020
The anatomy of wood and charcoal was analyzed by scanning electron microscopy in three radial positions of E. urophylla and E. Grandis in different diameter classes at six years. The carbonization process was given in the muffle with an average rate of 0.

Endoscopic ultrasound-guided gallbladder drainage by transduodenal lumen-apposing metal stent in a patient with Roux-en-Y reconstruction

Annals of gastroenterology : quarterly publication of the Hellenic Society of Gastroenterology, 2019
Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is increasingly recognized as an effective and safe treatment option in patients with acute cholecystitis (AC) who are deemed unfit for cholecystectomy. Recent studies suggest that an endoscopic
