Incident light orientation lets C4 monocotyledonous leaves make light work differently [PDF]

open access: yes, 2008
Photosynthesis is an important driver of ecosystem sustainability in the face of climate change. Monocotyledonous crop species with C4 photosynthesis such as maize (Zea mays L; corn) and sugar cane are crucial for future food security and biofuel crop ...

Increasing leaf hydraulic conductance with transpiration rate minimizes the water potential drawdown from stem to leaf. [PDF]

open access: yes, 2014
Leaf hydraulic conductance (k leaf) is a central element in the regulation of leaf water balance but the properties of k leaf remain uncertain. Here, the evidence for the following two models for k leaf in well-hydrated plants is evaluated: (i) k leaf is

Enhancing Surgical Efficiency and Cost‐Effectiveness With TaTME‐Combined Robot‐Assisted Surgery for Lower Rectal Cancer

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Robot‐assisted rectal surgery (RAS) offers improved dexterity and visualization; however, the high cost of equipment and consumables remains a major challenge for hospital management. At our institution, we have adopted a combined approach using transanal total mesorectal excision (TaTME) for lower rectal cancers, aiming to shorten ...

Short Distal Resection Margin Does Not Increase Recurrence Risk After R0 Resection for Rectal Neuroendocrine Tumors: A Single‐Institution Retrospective Study of 208 Patients

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study evaluated the impact of distal resection margin (DRM) length on recurrence in 208 patients undergoing surgery for rectal neuroendocrine tumors (NETs). Our findings demonstrate that while oncological safety must unquestionably remain the top priority, a short pathological DRM (< 10 mm) does not increase recurrence risk when R0 resection is ...

Integrated morphometric and functional stomatal responses of urban tree species to chronic air pollution

open access: yesDiscover Plants
Urban air pollution poses a persistent threat to tree health, yet species-specific stomatal responses and adaptive strategies under chronic pollution stress remain poorly understood.

Stomatal dynamics in Alloteropsis semialata arise from the evolving interplay between photosynthetic physiology, stomatal size and biochemistry

open access: yesPlant, Cell & Environment
AbstractC4 plants are expected to have faster stomatal movements than C3 species because they tend to have smaller guard cells. However, little is known about how the evolution of C4 photosynthesis influences stomatal dynamics in relation to guard cell size and environmental factors.

Relationship between stomatal density, size and speed of opening in Sumatran rainforest species [PDF]

open access: yesTree Physiology, 2017
Recent studies have suggested that an association between size and speed of stomatal opening of stomata within taxa is likely to play a role in photosynthesis and transpiration. In this study we investigate whether this correlation applies for seedlings of 11 rainforest species from different taxa, and whether differences in stomatal and gas exchange ...

First Successful Regeneration of a Structurally Native‐Like Colon Using a Bioabsorbable Polymer Sheet

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study demonstrated that a bioabsorbable polymer sheet (BAPS) can regenerate approximately half the circumference of the colon with native‐like structure and function in an experimental setting. As the model involved immediate closure after perforation and did not reproduce peritonitis, caution is required when considering clinical applicability ...

Are Cytological and Morphological Analyses Sufficient in Ploidy Determination of Watermelon Haploid Plants?

open access: yesHorticulturae
Watermelon (Citrullus lanatus L. Thunb. Matsum. and Nakai) is a vegetable species with high water content that is rich in lycopene and refreshing; therefore, breeding studies are carried out intensively to develop new varieties.
