Fruit and Vegetable Intake and Mental Health in Adults
High total intake of fruits and vegetables, and some of their specific subgroups including berries, citrus, and green leafy vegetables, may promote higher levels of optimism and self-efficacy, as well as reduce the level of psychological distress, ambiguity, and cancer fatalism, and protect against depressive symptoms. The general recommendation to consume at least 5 portions of fruit and vegetables a day may be beneficial also for mental health.

ESKAPE Bacteria in the Dog
ESKAPE bacteria (i.e., Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) are a group of common opportunistic pathogens associated mainly with nosocomial infections.

NAD+ Biology in Kidney and Renal Disease
Nicotinamide Adenine Dinucleotide (NAD+) and its reduced form NADH, by regulating redox reactions and allowing the production of adenosine triphosphate (ATP), are crucial for energy metabolism and fatty acid β-oxidation (FAO) in proximal tubular epithelial cells (PTECs). In addition, by being the substrate of non-redox NAD+-consuming enzymes such as sirtuins and poly(ADP-ribose) polymerases (PARPs), NAD+ is also involved in several key molecular mechanisms for cellular homeostasis. NAD+ is present in the kidney at concentrations ranging from 0.3 to 1 mmol/kg of tissue, which is comparable to concentrations found in liver and muscle.

Curcumin as an Antibacterial Agent
The rapid spread of antibiotic resistance and lack of effective drugs for treating infections caused by multi-drug resistant bacteria in animal and human medicine have forced us to find new antibacterial strategies. Natural products have served as powerful therapeutics against bacterial infection and are still an important source for the discovery of novel antibacterial drugs. Curcumin, an important constituent of turmeric, is considered safe for oral consumption to treat bacterial infections. Many studies showed that curcumin exhibited antibacterial activities against Gram-negative and Gram-positive bacteria. The antibacterial action of curcumin involves the disruption of the bacterial membrane, inhibition of the production of bacterial virulence factors and biofilm formation, and the induction of oxidative stress. These characteristics also contribute to explain how curcumin acts a broad-spectrum antibacterial adjuvant, which was evidenced by the markedly additive or synergistical effects with various types of conventional antibiotics or non-antibiotic compounds.

Antihypertensives’ around the Clock
Although homeostasis is a commonly accepted concept, there is incontrovertible evidence that biological processes and functions are variable, and that variability occurs in cycles. So allostatic model has emerged as the first challenge to homeostasis. Circadian variation is the predominant variation in the body. As there is strong scientific and clinical evidence that blood pressure fluctuations undergo circadian rhythm, there is equally strong evidence that targeted time therapy for hypertension provides a better outcome of the disease. The research has gone even further by ensuring better patients' adherence throughout the development and approval process for the use of pulsatile drug release systems which can be considered as an option for an even more convenient dosage regimen of the medicines needed.

Corneal Infection Models: Bacterial Keratitis
Corneal infection models are tools which can be used to study host-pathogen interactions at the corneal surface. They are highly valuable in the study of bacterial keratitis, a potentially sight-threatening eye infection, localised to the cornea. During bacterial keratitis, bacteria colonise the cornea as biofilm populations which demonstrate an increased resistance to antibiotics and the host immune response. Therefore the presence or absence of biofilm is an important consideration in model development. Corneal infection models include: in vitro models (which use cell culture techniques to generate 3D corneal constructs), ex vivo models (which use whole, excised corneas) and in vivo models (which use live animals).

Biological Theories of Dyslexia
The primary symptoms of dyslexia were first identified by Oswald Berkhan in 1881. The term dyslexia was coined in 1887 by Rudolf Berlin, an ophthalmologist practicing in Stuttgart, Germany . Since then generations of researchers have been investigating what dyslexia is and trying to identify the biological causes. The theories of the etiology of dyslexia have and are evolving with each new generation of dyslexia researchers, and the more recent theories of dyslexia tend to enhance one or more of the older theories as understanding of the nature of dyslexia evolves. Theories should not be viewed as competing, but as attempting to explain the underlying causes of a similar set of symptoms from a variety of research perspectives and background.

Pyrimidine Biosynthetic Enzyme CAD
CAD (Carbamoyl-phosphate synthetase 2, Aspartate transcarbamoylase, and Dihydroorotase) is a multifunctional protein that participates in the initial three speed-limiting steps of pyrimidine nucleotide synthesis. Over the past two decades, extensive investigations have been conducted to unmask CAD as a central player for the synthesis of nucleic acids, active intermediates, and cell membranes. Meanwhile, the important role of CAD in various physiopathological processes has also been emphasized.

Metabolic Reprogramming in Cancer Cells
Cancer cells alter metabolic processes to sustain their characteristic uncontrolled growth and proliferation. Altered metabolic flux in cancer is controlled by tumor-host cell interactions, key oncogenes, tumor suppressors, and other regulatory molecules, including non-coding RNAs. Changes to metabolic pathways in cancer are dynamic, exhibit plasticity, and are often dependent on the type of tumor and the tumor microenvironment, leading in a shift of thought from the Warburg Effect and the “reverse Warburg Effect” to metabolic plasticity.
