Pharmacological Activities of Hovenia dulcis Extracts
Hovenia dulcis Thunberg is an herbal plant, belonging to the Rhamnaceae family, widespread in west Asia, USA, Australia and New Zealand, but still almost unknown in Western countries. H. dulcis has been described to possess several pharmacological properties, such as antidiabetic, anticancer, antioxidant, anti-inflammatory and hepatoprotective, especially in the hangover treatment, validating its use as an herbal remedy in the Chinese Traditional Medicine. The biological activities of H. dulcis crude extracts and secondary metabolites isolated from them highlighted promising pharmacological effects in vitro and in vivo.

Intra-Arterial Delivery of Therapeutics
Diseases of the kidney contribute a significant morbidity and mortality burden on society. Localized delivery of therapeutics directly into the kidney, via its arterial blood supply, has the potential to enhance their therapeutic efficacy while limiting side effects associated with conventional systemic delivery. Targeted delivery in humans is feasible given that we can access the renal arterial blood supply using minimally invasive endovascular techniques and imaging guidance. Techniques to reproduce or mimic this approach in a small animal model  will allow for further pre-clinical translational studies investigating therapies for the treatment of renal pathologies.

Challenges in Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) is an immune-mediated multi-systemic disease characterized by a wide variability of clinical manifestations and a course frequently subject to unpredictable flares. Despite significant advances in the understanding of the pathophysiology and optimization of medical care, patients with SLE still have significant mortality and carry a risk of progressive organ damage accrual and reduced health-related quality of life.

FAHFAs
Fatty Acid esters of Hydroxy Fatty Acids (FAHFAs) are ester derivatives of fatty acids (FAs) with hydroxy fatty acids (HFAs) carrying the hydroxyl group at different positions. This novel class of endogenously generated lipids, discovered in 2014, has attracted the interest, because such lipids have been found to exhibit anti-diabetic and anti-inflammatory effects. The great number of possible combinations of FAs with HFAs together with the great number of possible positional isomers makes the analysis of FAHFAs very challenging. FAHFAs have been detected and quantified in a variety of human and animal tissues, as well as in plant tissues and foods. Analytical methodologies, either targeted or untargeted, may highly contribute in studying FAHFA levels under various biomedical conditions, and in understanding their role in physiological and pathological conditions.

Fungal Enzymes Involved in Plastics Biodegradation
Plastic pollution is a growing environmental problem, in part due to the extremely stable and durable nature of this polymer. As recycling does not provide a complete solution, research has been focusing on alternative ways of degrading plastic. Fungi provide a wide array of enzymes specialized in the degradation of recalcitrant substances and are very promising candidates in the field of plastic degradation.

Pexophagy in Plants
Autophagy, or self-eating, is a conservative process that occurs in yeast, animal, and plant cells, and primarily involves the degradation of cytoplasmic fragments along with organelles, protein complexes, and other macromolecules. In plants, autophagy participates in the circulation of cell components and acts as a quality control mechanism.

Intracellular Signalling in Wound Healing
The cells response to injury is initiated by growth factors and cytokines that play a key role in wound restoration, and their biological action is achieved via signal transduction. Growth factors and cytokines play distinct roles through all phases of wound healing. In response to injury, they can trigger several strategic signalling transduction pathways that are mostly activated during embryonic skin development. Extracellular signal-regulated kinases (ERKs) and calcium (Ca2+) are the first intracellular signalling molecules for tissue repair response. These signalling molecules regulate several biological activities including cellular migration, proliferation, contractility, survival and many more related to different transcription factors that are usually induced by several other intracellular signalling pathways. This phenomenon makes it difficult to link a specific signalling response to injury.

Mechanisms of Snake Venom Induced Pain
Not all venoms contain the same constituents; not all sensory neurons or other components of the nervous system are vulnerable to the same peptide or enzyme; not all tissues and organs have the same innervation or vulnerability to venom constituents; and, lastly, snakes have incredibly diverse venom proteomes, a diversity driven by geographical and other environmental factors. Documentation of specific pain syndromes in greater detail in future epidemiological studies of snake bite is also critical.

Bifunctional Non-Canonical Amino Acids
Genetic code expansion is a powerful tool for the study of protein interactions, as it allows for the site-specific incorporation of a photoreactive group via non-canonical amino acids. Recently, several groups have published bifunctional amino acids that carry a handle for click chemistry in addition to the photo-crosslinker. This allows for the specific labeling of crosslinked proteins and therefore the pulldown of peptides for further analysis. This review describes the properties and advantages of different bifunctional amino acids, and gives an overview about current and future applications.

The Microbiome in Obesity
Obesity has become a global epidemic and a public health crisis in the Western World, experiencing a threefold increase in prevalence since 1975. High-caloric diets and sedentary lifestyles have been identified as significant contributors to this widespread issue, although the role of genetic, social, and environmental factors in obesity’s pathogenesis remain incompletely understood. In recent years, much attention has been drawn to the contribution of the gut microbiota in the development of obesity, driven by a body of evidence supporting its central role in regulation of host physiology. Indeed, research has shown that in contrast to their healthier counterparts the microbiomes of obese individuals are structurally and functionally distinct, strongly suggesting gut dysbiosis as a key factor underpinning an obese phenotype. The following entry  explores the myriad of mechanisms by which the microbiome may contribute to the etiology of obesity, including modulation of host energy balance, immune function and macronutrient metabolism.
