Finite mesophyll conductance (g) reduces the rate of CO diffusion from the leaf intercellular space to the chloroplast and constitutes a major limitation of photosynthesis in trees. While it is well established that g is decreased by stressors such as drought and high temperature, few studies have investigated if the phytotoxic air pollutant ozone (O) affects g. We quantified the relative importance of three different types of limitations of photosynthesis in poplar trees exposed to elevated O: decreases in stomatal conductance, g and biochemical photosynthetic capacity.

All tissues are surrounded by a mixture of noncellular matrix components, that not only provide physical and mechanical support to cells, but also mediate biochemical signaling between cells. The extracellular matrix (ECM) of endothelial cells, also known as the perivascular matrix, forms an organ specific vascular niche that orchestrates mechano-, growth factor, and angiocrine signaling required for tissue homeostasis and organ repair. This concise review describes how this perivascular ECM functions as a signaling platform and how this knowledge can impact the field of regenerative medicine, for example, when designing artificial matrices or using decellularized scaffolds from organs.

To investigate immune profile consisting of stromal PD-L1 expression, inhibitory or non-T-cell inflamed tumor microenvironment that may predict response to anti-PD-L1/PD-1 immunotherapy in prostate cancer, we validated the specificity of a PD-L1 monoclonal antibody (E1L3N) and identified PD-L1 specific expression in prostatic stromal nerve cells. PD-L1 expression was analyzed in 73 primary prostate cancers and 7 castration-resistant prostate cancers (CRPC) by IHC and resulting data from primary prostate cancers were correlated with tumor-associated lymphocytes (TALs), clinicopathological characteristics and clinical outcome. PD-L1 was expressed in the tumor cells in only one primary prostate cancer case and none of the CRPC. Read More

Mechanical instability of bone implants stimulate osteoclast differentiation and peri-implant bone loss, leading to prosthetic loosening. It is unclear which cells at the periprosthetic interface transduce mechanical signals into a biochemical response, and subsequently facilitate bone loss. We hypothesized that mechanical overloading of hematopoietic bone marrow progenitor cells, which are located near to the inserted bone implants, stimulates the release of osteoclast-inducing soluble factors.

Tissue-engineered menisci hold promise as an alternative to allograft procedures but require a means of robust fixation to the native bone. The insertion of the meniscus into bone is critical for meniscal function and inclusion of a soft tissue-to-bone interface in a tissue engineered implant can aid in the fixation process. The native insertion is characterized by gradients in composition, tissue architecture, and cellular phenotype, which are all difficult to replicate. Read More

Extracellular vesicles (EVs) were isolated by ultracentrifugation of vaginal luminal fluid (VLF) from superovulated mice and identified for the first time using transmission electron microscopy. Characterized by size and biochemical markers (CD9 and HSC70), EVs were shown to be both microvesicular and exosomal and were dubbed as "Vaginosomes" (VGS). Vaginal cross-sections were analyzed to visualize EVs in situ: EVs were present in the lumen and also embedded between squamous epithelial and keratinized cells, consistent with their endogenous origin.

Characterization of single cell metabolism is imperative for understanding subcellular functional and biochemical changes associated with healthy tissue development and the progression of numerous diseases. However, single-cell analysis often requires the use of fluorescent tags and cell lysis followed by genomic profiling to identify the cellular heterogeneity. Identifying individual cells in a noninvasive and label-free manner is crucial for the detection of energy metabolism which will discriminate cell types and most importantly critical for maintaining cell viability for further analysis.

Efforts to limit global warming to below 2°C in relation to the pre-industrial level are under way, in accordance with the 2015 Paris Agreement.

Pheochromocytomas (PCC) and paragangliomas (PGL), collectively abbreviated PPGL are rare tumours originating from the chromaffin cells in the adrenal medulla (PCC) or the sympathetic or parasympathetic extra-adrenal paraganglia (PGL) (1, 2), Figure 1. The enlarged cell volume leads to increased levels of catecholamines (adrenaline, noraderenaline and/or dopamine) and their metabolites which can be measured in plasma or urine for biochemical diagnosis. Hormone-producing PPGL commonly originate from sympathetic paraganglia in the adrenal glands, abdomen or pelvis (3). Read More

Information in the brain is stored in a form of an altered synaptic strength between neurons. The long-term potentiation (LTP), a phenomenon when a short-term increase in neural activity is transformed into a long-lasting increase in strengths of synaptic connectivity, provides an experimental substrate of memory. Using reaction-diffusion equations, we established an LTP model, describing the dynamics of glutamate (Glu), calcium (Ca) and nitric oxide (NO) in response to the stimulus-a presynaptic action potential.

Mitochondrial permeabilization is a key event in the intrinsic pathway of apoptosis, and is mediated by either of the BCL-2 family members BAK or BAX. These two proteins generate pores in the mitochondrial outer membrane that release factors such as cytochrome c into the cytosol to trigger caspase activation and apoptotic cell death. To generate pores, BAK and BAX undergo major changes including BAX translocation to the outer membrane, and partial unfolding, dimerization, and oligomerization. Read More

Among the different models used to study the biochemical properties and function of proteins of the Bcl-2 family, their heterologous expression in the yeast Saccharomyces cerevisiae may look out of place. However, when grown under adequate conditions, yeast cells have mitochondria that have similar properties as those of mammalian cells, and are able to be targeted by mammalian Bcl-2 family members. Yeast thus provides a neutral cellular background to study how proteins of the Bcl-2 family interact with mitochondria, alone or as a couple (or a combination of more proteins). Read More

The blood-brain barrier (BBB) is a structural and functional barrier between the interstitial fluid of the brain and the blood; the barrier maintains the precisely controlled biochemical environment that is necessary for neural function. This constellation of endothelial cells, macrophages, pericytes, and astrocytes forms the neurovascular unit which is the structural and functional unit of the blood-brain barrier.

Primary mitochondrial disorders are highly variable in clinical presentation, biochemistry, and molecular etiology. Mitochondrial disorders can be caused by genetic defects in the mitochondrial, in nuclear genome, or in the interplay between the two genomes.

The use of treated organic products as fertilizers and soil amendments not only results in economic benefits for the small-scale farmer, but it also reduces pollution due to reduced nutrient run-off and N leaching. In this work, the feasibility of using composts as fertilizers and soil improvers has been evaluated at the field level, in barley and soft wheat crops (two successive cultivations of each crop). The applied treatments consisted of two commercial composts (compost manure and sewage sludge compost) added to the soil either alone (T1 and T3) or in combination with inorganic fertilizers (T2 and T4) and a conventional mineral fertilization (T5).

Metabolism is highly coordinated component of the cellular activity that involves sequential chemical transformations, within a so-called metabolic network. Through these coordinated actions, living organisms acquire energy and biosynthetic precursors to maintain cellular homeostasis and function. Metabolism relies on the breaking down of macromolecules to produce energy [catabolism] and/or intermediary metabolites that are then used to construct essential building blocks for macromolecule production [anabolism].
